Impressed with Franken’s experience, openness

We invited Admiral Mike Franken to a gathering of voters to explain why he was qualified to run for the U.S. Senate. We were impressed with his friendliness, his openness, and especially his range of experience as a leader. One of those in attendance at our home was a woman who had served under his command on the U.S.S. Barry; it was a happy reunion for the sailor and the admiral. She had no hesitation in endorsing him and supporting him in his campaign. Admiral Franken also visited our son’s home in another city. Again, those gathered were impressed with Admiral Franken’s experiences and priorities But the person most impressed was our eight-year-old grandson. When Charlie walked into the room, Admiral Franken interrupted himself, introduced himself to Charlie and engaged him in genuine conversation. Charlie’s summation of politicians. “I like him. He was talking about boring stuff, but he was nice to me. People shouldn’t talk about boring stuff; they should just be nice to everyone.”

Mike doesn’t talk about boring stuff — to us, anyway. He talks about the actions we want our United States Senate to take: pass legislation to address climate change, health care and the economy.

Because Mike has experience as a leader and as a staff member on Capitol Hill, he has an advantage over newcomers to Washington.

We, one Democrat and one Republican, encourage you to vote for Admiral Mike Franken to be our Senator.

Uptown Marion Market opening with caveats

MARION — While the Uptown Marion Market will continue to sell fresh produce, it will look a little different this year.

The market will continue operating on the second Saturday of June, July and August with some adjustments.

But the city of Marion has canceled community events until at least early July because of the coronavirus pandemic.

The Uptown market will run along Sixth Avenue instead of being held in City Square Park. It will be fenced and no more than 50 people will be let in at an time.

Jill Ackerman, president of the Marion Chamber of Commerce, said there are usually between 50 and 60 vendors at each market, but she expects only 15 to 25 at this summer’s markets.

“The main thing here is safety,” Ackerman said. “We want to make sure people have opportunities to buy fresh produce from our local growers, but we’re going to ask patrons to only spend 30 minutes inside the market.”

Vendors will sell produce and some plants, but artisan items will not be available.

While there will be summer events through the Chamber of Commerce, Ackerman said, they will be fewer and look a little different than they usually do.

Free community concerts and movie nights are canceled until July by the city, according to a news release.

The Marion Farmers Market, held at Taube Park, is expected to resume May 16.

Officials hope to have smaller-scale events throughout the summer like performances in the Uptown Artway, Messy Art Days and the Tiny Fair series as restrictions ease.

Sunrise Yoga at the Klopfenstein Amphitheater at Lowe Park is expected to take place every Saturday from June to August.

“Unfortunately, given our current reality, we know that 2020 will be far from normal,” said Marion Mayor Nicolas AbouAssaly. “After careful consideration and consultation with event organizers and sponsors, we have made the collective decision to cancel the free community concerts, events and movie nights originally planned for our outdoor public venues through early-July.”

Ahead of VP Pence’s Iowa visit, Joe Biden’s campaign calls out ‘consequential failure’ of Trump coronavirus response

Vice President Mike Pence owes Iowans more than a photo-op when he visits Des Moines today, according to Joe Biden’s campaign.

“Iowans are seeing up close the most consequential failure of government in modern American history,” said Kate Bedingfeld, spokeswoman for the former vice president and presumptive Democratic presidential nominee.

“With nearly 300,000 Iowans filing for unemployment, rural hospitals on life support, Latino communities disproportionately suffering and workers on the job without sufficient protection, Mike Pence owes Iowans more than a photo-op — he owes them answers,” she said.

Pence, head of the White House coronavirus task force, is scheduled to meet with Iowa Gov. Kim Reynolds and U.S. Sens. Chuck Grassley and Joni Ernst, all Republicans, as well as with faith, farm and food production leaders.

Pence will talk to faith leaders about how they are using federal and state guidelines to open their houses of worship in a safe and responsible manner.

Later, he will go to Hy-Vee’s headquarters in West Des Moines for a roundtable discussion with agriculture and food supply leaders to discuss steps being taken to ensure the food supply remains secure.

Pence has called Iowa a “success story” in its response to the COVID-19, but Bedingfeld said the Trump administration failed to protect Iowa families from the virus that has claimed the lives of 231 Iowans.

“From devastating losses across the state, at meatpacking plants to rural communities, one thing is clear — it’s Iowans and the American people who are paying the price for the Trump administration’s denials and delays in response to this pandemic,” she said.

“Instead of listening to our own intelligence agencies and public health experts, Donald Trump was fed dangerous propaganda from the Chinese Communist Party — and he bought it,” she said. “Iowans deserve better — they deserve Joe Biden.”

For his part, Grassley said he welcomes the discussion with Pence.

“There’s much work to be done, and the pandemic is disrupting all of our communities,” Grassley said. “It’s important to hear directly from those who help feed the nation and the world.”

Ernst also is looking forward to the discussion of how Iowa is working to protect the health and safety of Iowa’s families and communities while reopening the state’s economy.

“We continue to take an all-hands-on-deck approach to tackling this pandemic,” she said. “Together, we will get through this.”

Ready to reopen? Four Cedar Rapids business leaders offer advice

On Wednesday, Gov. Kim Reynolds removed some restrictions on businesses in the 22 counties that have been seeing higher numbers of Iowans affected by COVID-19, including Linn and Johnson counties.

Now those organizations have to make decisions — on bringing back employees, services to provide and how much access to allow for customers.

And as those businesses reopen — some after more than two months — crucial steps likely will include ongoing communication with employees and customers and a well-thought-out restart plan.

The Gazette spoke with business leaders about the challenges faced by business owners as they consider how and when to open their doors.

• David Drewelow of ActionCoach Heartland in Cedar Rapids is a consultant with 19 years of business coaching experience.

• David Hensley, director of the University of Iowa’s John Pappajohn Entrepreneurial Center, has expertise in small business management during a crisis.

• Josh Seamans is vice president of Cushman and Wakefield, a global commercial real estate adviser that operates offices in more than 60 countries including China.

• Steve Shriver is a Cedar Rapids entrepreneur who operates and/or helped found four diverse enterprises, including Eco Lips and Brewhemia.

Their responses here have been condensed from lengthy individual interviews.

How important is communication and having a well-prepared plan for resumption of business?

Shriver: The one thing that has been imperative throughout this whole process is communication with employees, customers and the public. I also would recommend writing as detailed a business resumption plan as possible.

One of the main reasons is to fully understand what you are doing as this is a brand-new challenge that none of us has faced.

Drewelow: You really need to be communicating now, more than ever, with your employees, customers, vendors and suppliers. What does your plan for the next 20 to 30 days look like? What are things that you can be doing right now to get ready?

Hensley: I think it is critically important to have a reopening plan because most businesses are not going to be at full strength right away. What might their revenue forecasts look like? How can they keep their costs down as their business starts to rebound before it gets back to full capacity?

Seamans: Your plan should include a checklist of reopening steps appropriate to your type of business. Retail will have different items than distribution or industrial businesses.

You need to communicate your plan to employees, customers, landlords and lenders.

How much will fear play a role in the resumption of business?

Shriver: Everyone has a different idea of the risks involved, such as using a handle to open a door or interacting with a person — the little things that we are used to doing.

When you look at the risk versus reward of doing that, some people will be willing to go into a store and others will stay home. Some employees don’t want to come back to work yet and some people are itching to get back. You have everything in between.

Drewelow: The fear factor is huge. For the small business owner, we try to channel that fear into a focus on being highly aware of all the possibilities to mitigate concerns.

If you own a restaurant, can you post the menu online or use disposable menus? That way, a customer doesn’t have to touch something that might have been handled by someone else.

Appropriate spacing of customers within a restaurant also will help alleviate some of the fear.

Hensley: You need to communicate what steps you are taking to protect the health and safety of your employees and your customers. If you will be requiring the use of personal protective equipment like face masks, are you going to make them available?

Will limiting the number of people entering a business be difficult?

Shriver: There are not a lot of people who want to gather in masses right now. It seems like as businesses start to reopen, it will be more like a trickle.

It will be just like turning on a water spigot, with the flow of customers gradually increasing.

Hensley: I think we will see a lot more customers buying, rather than just shopping. They are going to buy the items they came for and then leave.

If businesses have more vulnerable customers, I would recommend establishing separate early morning times like many of the grocery stores have done to provide a safer environment.

Many companies have adopted using digital conferencing platforms for meetings. Will we see that trend continue?

Seamans: I think Zoom will be used for more internal meetings, so there is no need for someone to fly from, say, San Francisco to New York. But in terms of sales, it does not replicate that face-to-face interaction.

We have done work with clients that live several hours away and we have to come in for a city council meeting for a project that we are working on. That’s a three-hour drive in for a one- or two-hour council meeting and another three-hour drive back — basically an eight-hour day. If we can Zoom in and answer any questions, that’s a lot more efficient at less cost.

What should a small-business owner consider when determining how many employees to recall?

Shriver: We will be able to bring some people back to work and generate some revenue, but not in a huge way. Anybody who can work from home should continue working from home for as long as they possibly can.

We should not be rushing to get those people back. There is no incentive.

Hensley: Owners are going to be making hard decisions. Do I bring back half of my team at full time or do I bring everyone back at reduced hours? What are those implications going to be?

In some cases, other industries have been hiring and some may be making more money. Businesses may have to pay more to attract that talent back.

Restaurants have been forced to change their business model from on-premise dining to carryout and delivery. Should all owners take this opportunity to examine and update their business model?

Shriver: We took two businesses — SOKO Outfitters, a retail store, and Brewhemia, a restaurant — and put them rapidly online within a month. When we come out of this, I think we will be stronger because we will have that infrastructure in place in addition to the old school face to face traffic that we used to have.

Hensley: I think this is definitely the time to look at your business model to determine what is appropriate given the economic situation that we have. That is not just going to be critical for reopening, but over the next six months to a year as long as we are dealing with the virus.

Some business owners will see that their customers have lost their jobs or seen their income drop dramatically. They are going to be changing their patterns of consumption based on necessities.

Drewelow: Some of my clients believe that are looking their competitors and realize that some may not reopen. They are looking at whether they can merge with them or somehow salvage parts of that business.

Some business owners have realized that the way they deliver products or services will have to change. Many of my older clients have been dragged into using modern technology.

Campgrounds reopen in Iowa Friday, see takers despite some health limitations

Some Eastern Iowans are ready to go camping.

With Gov. Kim Reynolds allowing campgrounds across the state to open Friday, some people wasted little time in heading outdoors.

“They’re already starting to fill up,” said Ryan Schlader of Linn County Conservation. “By about 7 this morning, we had a dozen at Squaw Creek Park. People were coming in bright and early to camp. We’re not surprised.”

Schlader said Linn County Conservation tried to have the campgrounds open at the county’s Squaw Creek, Morgan Creek and Pinicon Ridge parks at 5 a.m. Friday. He expected all of them would be busy.

“I think people were ready to go,” he said.

Lake Macbride State Park in Johnson County didn’t see quite as much of a rush for campsites, park manager Ron Puettmann reported Friday morning, saying he’d had six walk-ins for the park’s 42 campsites.

Camping this weekend will be done on a first-come, first-served basis. Sites won’t be available for reservations until next week, though online reservations can be made now, Puettmann said.

“I’m quite sure people were waiting anxiously to get on,” he said.

While Reynolds’ campground announcement came Wednesday, Schlader and Puettmann said they had no issues having the campgrounds ready for Friday.

Schlader said county staff have been in touch with the Iowa Department of Natural Resources and other county conservation boards to discuss protocols for reopening to ensure a safe experience for campers and employers.

“We anticipated at some point the order would be lifted,” Schlader said. “We were anticipating maybe May 15. The campgrounds were in good shape and ready to go.”

For now, camping comes with some limitations:

• Campers can camp only in a self-contained unit with a functioning restroom, such as a recreational vehicle.

• Shower houses with restrooms will remain closed for the time being.

• Campsites are limited to six people unless they are from the same household.

• No visitors are allowed at the campsites.

Puettmann said staffers and a DNR officer will be on hand to make sure guidelines are followed, but he didn’t anticipate enforcement would be an issue.

“For the most part, we’re going to allow people to police themselves,” he said.

It’s hard to gauge demand, Schlader said.

The weather isn’t yet deal for camping, and some people might not be ready to camp, given the continuing coronavirus.

“There is a lot of uncertainty,” he said. “Do people feel like they need to get out and enjoy a camping experience within their own campsite, or do people still feel under the weather and think it’s not a good idea for my family to go right now? ... We just want this to be an option for people.”

Pence’s Iowa visit underscores coronavirus worry

DES MOINES — In traveling to Iowa to call attention to the burdens COVID-19 brought to religious services and the food supply, Vice President Mike Pence unwittingly called attention to another issue: whether the White House itself is safe from the disease.

So far this week, two White House aides — President Donald Trump’s valet on Thursday, and Pence’s press secretary on Friday — have tested positive for the virus.

On Friday morning, Pence’s departure to Des Moines was delayed an hour as Air Force Two idled on a tarmac near Washington. Though Pence’s press secretary was not on the plane, White House physicians through contact tracing identified six other aides who had been near her who were aboard, and pulled them from the flight. The White House later said the six had tested negative.

Trump, who identified the Pence aide as press secretary Katie Miller, said he was “not worried” about the virus in the White House.

Nonetheless, officials said they were stepping up safety protocols and were considering a mandatory mask policy for those in close contact with Trump and Pence.

The vice president and 10 members of his staff are given rapid coronavirus tests daily, and the president is also tested regularly.

Miller, who is married to Trump adviser Stephen Miller, had been in recent contact with Pence but not with the president. Pence is leader of the White House coronavirus task force and Katie Miller has handled the group’s communications.

After landing in Des Moines, Pence spoke to a group of faith leaders about the importance of resuming religious services, saying cancellations in the name of slowing the spread of the virus have “been a burden” for congregants.

His visit coincided with the state announcing 12 more deaths from the virus, a total of 243 in less than two months.

Pence spoke with the religious leaders and Republican officials during a brief visit. He also spoke later with agricultural and food company executives.

“It’s been a source of heartache for people across the country,” Pence told about a dozen people at the Church of the Way Presbyterian church in Urbandale.

Pence told the group that continued efforts to hold services online and in other ways “made incalculable difference in our nation seeing our way through these troubled times.”

Iowa is among many states where restrictions on in-person services are starting to ease. GOP Gov. Kim Reynolds, who joined both of the state’s Republican senators at the event, has instituted new rules that allow services to resume with restrictions.

At Friday’s event, some religious leaders expressed hesitation at resuming large gatherings, while others said they would begin holding services soon,

“We are pretty much in a position of uniformly believing that it’s too early to return to personal worship. It’s inadvisable at the moment particularly with rising case counts in communities where we are across the state,” said David Kaufman, rabbi of Temple B’nai Jeshurun in Des Moines.

The Rev. Terry Amann, of Church of the Way, said his church will resume services May 17 with chairs arranged so families can sit together but avoid the temptation to shake hands or offer hugs. He said hand sanitizer will be available.

A new poll by The University of Chicago Divinity School and the Associated Press-NORC Center for Public Affairs Research shows just 9 percent of Americans think in-person services should be allowed without restrictions, while 42 percent think they should be allowed with restrictions and 48 percent think they shouldn’t be allowed at all.

Pence later met with agriculture and food industry leaders. Iowa tops the nation in egg production and pork processing and is a top grower of corn and soybeans.

Meatpacking is among the state’s biggest employers, and companies have been working to restart operations after closing them because hundreds of their workers became infected.

As Pence touted the Trump administration’s announcement of the reopening of 14 meatpacking plants including two of the worst hit by coronavirus infections in Perry and Waterloo, the union representing workers called for safer work conditions.

“Iowa’s meatpacking workers are not sacrificial lambs. They have been working tirelessly during the coronavirus pandemic to ensure families here and across the country have access to the food they need,” said the United Food and Commercial Workers Union in a statement.

The Associated Press and the McClatchy Washington Bureau contributed to this report.

Triangles in graphs without bipartite suspensions. (arXiv:2004.11930v2 [math.CO] UPDATED)

Given graphs $T$ and $H$, the generalized Tur'an number ex$(n,T,H)$ is the maximum number of copies of $T$ in an $n$-vertex graph with no copies of $H$. Alon and Shikhelman, using a result of ErdH os, determined the asymptotics of ex$(n,K_3,H)$ when the chromatic number of $H$ is greater than 3 and proved several results when $H$ is bipartite. We consider this problem when $H$ has chromatic number 3. Even this special case for the following relatively simple 3-chromatic graphs appears to be challenging.

The suspension $widehat H$ of a graph $H$ is the graph obtained from $H$ by adding a new vertex adjacent to all vertices of $H$. We give new upper and lower bounds on ex$(n,K_3,widehat{H})$ when $H$ is a path, even cycle, or complete bipartite graph. One of the main tools we use is the triangle removal lemma, but it is unclear if much stronger statements can be proved without using the removal lemma.

Three-point Functions in $mathcal{N}=4$ SYM at Finite $N_c$ and Background Independence. (arXiv:2002.07216v2 [hep-th] UPDATED)

We compute non-extremal three-point functions of scalar operators in $mathcal{N}=4$ super Yang-Mills at tree-level in $g_{YM}$ and at finite $N_c$, using the operator basis of the restricted Schur characters. We make use of the diagrammatic methods called quiver calculus to simplify the three-point functions. The results involve an invariant product of the generalized Racah-Wigner tensors ($6j$ symbols). Assuming that the invariant product is written by the Littlewood-Richardson coefficients, we show that the non-extremal three-point functions satisfy the large $N_c$ background independence; correspondence between the string excitations on $AdS_5 imes S^5$ and those in the LLM geometry.

Linear independence of generalized Poincar'{e} series for anti-de Sitter $3$-manifolds. (arXiv:2005.03308v1 [math.SP])

Let $Gamma$ be a discrete group acting properly discontinuously and isometrically on the three-dimensional anti-de Sitter space $mathrm{AdS}^{3}$, and $square$ the Laplacian which is a second-order hyperbolic differential operator. We study linear independence of a family of generalized Poincar'{e} series introduced by Kassel-Kobayashi [Adv. Math. 2016], which are defined by the $Gamma$-average of certain eigenfunctions on $mathrm{AdS}^{3}$. We prove that the multiplicities of $L^{2}$-eigenvalues of the hyperbolic Laplacian $square$ on $Gammaackslashmathrm{AdS}^{3}$ are unbounded when $Gamma$ is finitely generated. Moreover, we prove that the multiplicities of extit{stable $L^{2}$-eigenvalues} for compact anti-de Sitter $3$-manifolds are unbounded.

Improved RawNet with Feature Map Scaling for Text-independent Speaker Verification using Raw Waveforms. (arXiv:2004.00526v2 [eess.AS] UPDATED)

Recent advances in deep learning have facilitated the design of speaker verification systems that directly input raw waveforms. For example, RawNet extracts speaker embeddings from raw waveforms, which simplifies the process pipeline and demonstrates competitive performance. In this study, we improve RawNet by scaling feature maps using various methods. The proposed mechanism utilizes a scale vector that adopts a sigmoid non-linear function. It refers to a vector with dimensionality equal to the number of filters in a given feature map. Using a scale vector, we propose to scale the feature map multiplicatively, additively, or both. In addition, we investigate replacing the first convolution layer with the sinc-convolution layer of SincNet. Experiments performed on the VoxCeleb1 evaluation dataset demonstrate the effectiveness of the proposed methods, and the best performing system reduces the equal error rate by half compared to the original RawNet. Expanded evaluation results obtained using the VoxCeleb1-E and VoxCeleb-H protocols marginally outperform existing state-of-the-art systems.

Games Where You Can Play Optimally with Arena-Independent Finite Memory. (arXiv:2001.03894v2 [cs.GT] UPDATED)

For decades, two-player (antagonistic) games on graphs have been a framework of choice for many important problems in theoretical computer science. A notorious one is controller synthesis, which can be rephrased through the game-theoretic metaphor as the quest for a winning strategy of the system in a game against its antagonistic environment. Depending on the specification, optimal strategies might be simple or quite complex, for example having to use (possibly infinite) memory. Hence, research strives to understand which settings allow for simple strategies.

In 2005, Gimbert and Zielonka provided a complete characterization of preference relations (a formal framework to model specifications and game objectives) that admit memoryless optimal strategies for both players. In the last fifteen years however, practical applications have driven the community toward games with complex or multiple objectives, where memory -- finite or infinite -- is almost always required. Despite much effort, the exact frontiers of the class of preference relations that admit finite-memory optimal strategies still elude us.

In this work, we establish a complete characterization of preference relations that admit optimal strategies using arena-independent finite memory, generalizing the work of Gimbert and Zielonka to the finite-memory case. We also prove an equivalent to their celebrated corollary of great practical interest: if both players have optimal (arena-independent-)finite-memory strategies in all one-player games, then it is also the case in all two-player games. Finally, we pinpoint the boundaries of our results with regard to the literature: our work completely covers the case of arena-independent memory (e.g., multiple parity objectives, lower- and upper-bounded energy objectives), and paves the way to the arena-dependent case (e.g., multiple lower-bounded energy objectives).

Digital Twin: Enabling Technologies, Challenges and Open Research. (arXiv:1911.01276v3 [cs.CY] UPDATED)

Digital Twin technology is an emerging concept that has become the centre of attention for industry and, in more recent years, academia. The advancements in industry 4.0 concepts have facilitated its growth, particularly in the manufacturing industry. The Digital Twin is defined extensively but is best described as the effortless integration of data between a physical and virtual machine in either direction. The challenges, applications, and enabling technologies for Artificial Intelligence, Internet of Things (IoT) and Digital Twins are presented. A review of publications relating to Digital Twins is performed, producing a categorical review of recent papers. The review has categorised them by research areas: manufacturing, healthcare and smart cities, discussing a range of papers that reflect these areas and the current state of research. The paper provides an assessment of the enabling technologies, challenges and open research for Digital Twins.

Weighted Moore-Penrose inverses of arbitrary-order tensors. (arXiv:1812.03052v3 [math.NA] UPDATED)

Within the field of multilinear algebra, inverses and generalized inverses of tensors based on the Einstein product have been investigated over the past few years. In this paper, we explore the singular value decomposition and full-rank decomposition of arbitrary-order tensors using {it reshape} operation. Applying range and null space of tensors along with the reshape operation; we further study the Moore-Penrose inverse of tensors and their cancellation properties via the Einstein product. Then we discuss weighted Moore-Penrose inverses of arbitrary-order tensors using such product. Following a specific algebraic approach, a few characterizations and representations of these inverses are explored. In addition to this, we obtain a few necessary and sufficient conditions for the reverse-order law to hold for weighted Moore-Penrose inverses of arbitrary-order tensors.

ZebraLancer: Decentralized Crowdsourcing of Human Knowledge atop Open Blockchain. (arXiv:1803.01256v5 [cs.HC] UPDATED)

We design and implement the first private and anonymous decentralized crowdsourcing system ZebraLancer, and overcome two fundamental challenges of decentralizing crowdsourcing, i.e., data leakage and identity breach.

First, our outsource-then-prove methodology resolves the tension between the blockchain transparency and the data confidentiality to guarantee the basic utilities/fairness requirements of data crowdsourcing, thus ensuring: (i) a requester will not pay more than what data deserve, according to a policy announced when her task is published via the blockchain; (ii) each worker indeed gets a payment based on the policy, if he submits data to the blockchain; (iii) the above properties are realized not only without a central arbiter, but also without leaking the data to the open blockchain. Second, the transparency of blockchain allows one to infer private information about workers and requesters through their participation history. Simply enabling anonymity is seemingly attempting but will allow malicious workers to submit multiple times to reap rewards. ZebraLancer also overcomes this problem by allowing anonymous requests/submissions without sacrificing accountability. The idea behind is a subtle linkability: if a worker submits twice to a task, anyone can link the submissions, or else he stays anonymous and unlinkable across tasks. To realize this delicate linkability, we put forward a novel cryptographic concept, i.e., the common-prefix-linkable anonymous authentication. We remark the new anonymous authentication scheme might be of independent interest. Finally, we implement our protocol for a common image annotation task and deploy it in a test net of Ethereum. The experiment results show the applicability of our protocol atop the existing real-world blockchain.

Two Efficient Device Independent Quantum Dialogue Protocols. (arXiv:2005.03518v1 [quant-ph])

Quantum dialogue is a process of two way secure and simultaneous communication using a single channel. Recently, a Measurement Device Independent Quantum Dialogue (MDI-QD) protocol has been proposed (Quantum Information Processing 16.12 (2017): 305). To make the protocol secure against information leakage, the authors have discarded almost half of the qubits remaining after the error estimation phase. In this paper, we propose two modified versions of the MDI-QD protocol such that the number of discarded qubits is reduced to almost one-fourth of the remaining qubits after the error estimation phase. We use almost half of their discarded qubits along with their used qubits to make our protocol more efficient in qubits count. We show that both of our protocols are secure under the same adversarial model given in MDI-QD protocol.

Global Distribution of Google Scholar Citations: A Size-independent Institution-based Analysis. (arXiv:2005.03324v1 [cs.DL])

Most currently available schemes for performance based ranking of Universities or Research organizations, such as, Quacarelli Symonds (QS), Times Higher Education (THE), Shanghai University based All Research of World Universities (ARWU) use a variety of criteria that include productivity, citations, awards, reputation, etc., while Leiden and Scimago use only bibliometric indicators. The research performance evaluation in the aforesaid cases is based on bibliometric data from Web of Science or Scopus, which are commercially available priced databases. The coverage includes peer reviewed journals and conference proceedings. Google Scholar (GS) on the other hand, provides a free and open alternative to obtaining citations of papers available on the net, (though it is not clear exactly which journals are covered.) Citations are collected automatically from the net and also added to self created individual author profiles under Google Scholar Citations (GSC). This data was used by Webometrics Lab, Spain to create a ranked list of 4000+ institutions in 2016, based on citations from only the top 10 individual GSC profiles in each organization. (GSC excludes the top paper for reasons explained in the text; the simple selection procedure makes the ranked list size-independent as claimed by the Cybermetrics Lab). Using this data (Transparent Ranking TR, 2016), we find the regional and country wise distribution of GS-TR Citations. The size independent ranked list is subdivided into deciles of 400 institutions each and the number of institutions and citations of each country obtained for each decile. We test for correlation between institutional ranks between GS TR and the other ranking schemes for the top 20 institutions.

Specification and Automated Analysis of Inter-Parameter Dependencies in Web APIs. (arXiv:2005.03320v1 [cs.SE])

Web services often impose inter-parameter dependencies that restrict the way in which two or more input parameters can be combined to form valid calls to the service. Unfortunately, current specification languages for web services like the OpenAPI Specification (OAS) provide no support for the formal description of such dependencies, which makes it hardly possible to automatically discover and interact with services without human intervention. In this article, we present an approach for the specification and automated analysis of inter-parameter dependencies in web APIs. We first present a domain-specific language, called Inter-parameter Dependency Language (IDL), for the specification of dependencies among input parameters in web services. Then, we propose a mapping to translate an IDL document into a constraint satisfaction problem (CSP), enabling the automated analysis of IDL specifications using standard CSP-based reasoning operations. Specifically, we present a catalogue of nine analysis operations on IDL documents allowing to compute, for example, whether a given request satisfies all the dependencies of the service. Finally, we present a tool suite including an editor, a parser, an OAS extension, a constraint programming-aided library, and a test suite supporting IDL specifications and their analyses. Together, these contributions pave the way for a new range of specification-driven applications in areas such as code generation and testing.

CovidCTNet: An Open-Source Deep Learning Approach to Identify Covid-19 Using CT Image. (arXiv:2005.03059v1 [eess.IV])

Coronavirus disease 2019 (Covid-19) is highly contagious with limited treatment options. Early and accurate diagnosis of Covid-19 is crucial in reducing the spread of the disease and its accompanied mortality. Currently, detection by reverse transcriptase polymerase chain reaction (RT-PCR) is the gold standard of outpatient and inpatient detection of Covid-19. RT-PCR is a rapid method, however, its accuracy in detection is only ~70-75%. Another approved strategy is computed tomography (CT) imaging. CT imaging has a much higher sensitivity of ~80-98%, but similar accuracy of 70%. To enhance the accuracy of CT imaging detection, we developed an open-source set of algorithms called CovidCTNet that successfully differentiates Covid-19 from community-acquired pneumonia (CAP) and other lung diseases. CovidCTNet increases the accuracy of CT imaging detection to 90% compared to radiologists (70%). The model is designed to work with heterogeneous and small sample sizes independent of the CT imaging hardware. In order to facilitate the detection of Covid-19 globally and assist radiologists and physicians in the screening process, we are releasing all algorithms and parametric details in an open-source format. Open-source sharing of our CovidCTNet enables developers to rapidly improve and optimize services, while preserving user privacy and data ownership.

Extracting Headless MWEs from Dependency Parse Trees: Parsing, Tagging, and Joint Modeling Approaches. (arXiv:2005.03035v1 [cs.CL])

An interesting and frequent type of multi-word expression (MWE) is the headless MWE, for which there are no true internal syntactic dominance relations; examples include many named entities ("Wells Fargo") and dates ("July 5, 2020") as well as certain productive constructions ("blow for blow", "day after day"). Despite their special status and prevalence, current dependency-annotation schemes require treating such flat structures as if they had internal syntactic heads, and most current parsers handle them in the same fashion as headed constructions. Meanwhile, outside the context of parsing, taggers are typically used for identifying MWEs, but taggers might benefit from structural information. We empirically compare these two common strategies--parsing and tagging--for predicting flat MWEs. Additionally, we propose an efficient joint decoding algorithm that combines scores from both strategies. Experimental results on the MWE-Aware English Dependency Corpus and on six non-English dependency treebanks with frequent flat structures show that: (1) tagging is more accurate than parsing for identifying flat-structure MWEs, (2) our joint decoder reconciles the two different views and, for non-BERT features, leads to higher accuracies, and (3) most of the gains result from feature sharing between the parsers and taggers.
