TIPTON
Ann E. Hinkhouse, 74, died Tuesday May 5, 2020. Henderson-Barker Funeral Home, West Liberty.

ANN E. HINKHOUSE
Tipton

Ann E. Hinkhouse, 74, passed away Tuesday May 5, 2020, at the University of Iowa Hospitals and Clinics in Iowa City.
Graveside services will be held 11 a.m. Monday, May 11, at the Sharon Cemetery in rural Wilton. Visitation will be held from
9 to 10 a.m. Monday at the Henderson-Barker Funeral Home in West Liberty. Memorials may be made to Cedar County Friends of the Animals and Iowa City Hospice.
Ann Elaine Hinkhouse was born Sept. 25, 1945, in Iowa City, Iowa, the daughter of Nevin and Belle (Walton) Hinkhouse. She was a graduated from Lutheran Hospital Nursing School, received her B.A. from Cornell College and M.B.A. from St. Ambrose University. She was active in nursing all her life, working at Genesis Hospital in Davenport, University of Iowa, Crestview Care Center in West Branch, Cedar Manor Nursing Home in Tipton, Simpson Memorial Home in West Liberty and, most recently, at the Wilton Care Center. She enjoyed the family farm where she spent most of her life up until the sale in 2017, moving to Tipton. Ann worked as parish nurse for Zion Lutheran Church in Wilton for many years. She enjoyed raising sheep, gardening and embroidery work. She was a member of St. Paul's Lutheran Chapel in Iowa City, Tipton Rotary Club and Cedar County Historical Society Board.
Ann is survived by many cousins.
She was preceded in death by her parents; and brother, Steve, in 2017.

The upcoming primary election is a pivotal moment for Iowa City. For the past several months, I have talked to people throughout the district who are ready for change. They believe their Democratic representative should show up for people throughout the community, especially those in need. They expect a legislator from Iowa’s bluest district to be a leader in the party, raising money to support Democratic candidates up and down the ticket and making the strongest possible case for progressive legislation. They are ready to start now in building the future of the Democratic Party and state government in Iowa. And I am honored that they are putting their trust in me.

There is a lot at stake in this election. The coronavirus has laid bare and magnified preexisting inequities — inequities brought about by the Legislature’s disinvestment in education, health care, and worker rights and safety. Small businesses are now struggling to survive, when for years the state has been giving large corporations hundreds of millions of dollars in tax credits. Water quality, climate change and gun violence still need our attention, even as we continue to invest in keeping people safe from COVID-19. We have never needed strong leadership more than we do now.

I will be a champion for progressive values because I have lived them. I know how hard it can be for people to get by even when they work hard. I grew up in a trailer in rural Florida. Neither of my parents graduated high school. My dad was a construction worker who suffered for years with emphysema. When his health insurance was canceled, my family had to choose between paying for his medicine and everything else. Fortunately, public education gave me the opportunity for a better life. My teachers taught me well and helped me to apply to college. Public university tuition was affordable then, and I was able to work my way through engineering school and law school.

Today, I am a law professor, an environmental engineer and a mother. I believe I have the skills, energy and passion that Iowa City needs at this critical point in time. I will show up for every member of our community and fight for a better future for all of Iowa.

It’s time for change in Iowa City. Please vote for me in House District 85 and help to build the future that Iowa deserves.

Christina Bohannan is a candidate in the Democratic primary for Iowa House District 85.

Please join me in voting for Christina Bohannan for Iowa House of Representatives District 85. Christina is an energetic and passionate leader. She has broad experience as a law professor, an environmental engineer, and an advocate for diversity, equity and inclusion. These experiences give her a unique perspective and the ability to comprehend legislative issues from many different points of view. She sees the big picture and knows that she can support economic growth and small business while also advocating for basic human rights and fairness.

Christina shows up for people all over the community and is an advocate for people of color, immigrants, and others from disadvantaged or marginalized backgrounds.

An Iowa judge has ruled unconstitutional a state law that would have blocked Planned Parenthood of the Heartland from receiving federal money to provide sex education programs to Iowa youth.

Fifth Judicial District Judge Paul Scott on Wednesday ruled the law “has no valid, ‘realistically conceivable’ purpose that serves a legitimate government interest as it is both irrationally overinclusive and under-inclusive.”

“The act violates (Planned Parenthood of the Heartland’s) right to equal protection under the law and is therefore unconstitutional,” Scott ruled in issuing a permanent injunction to prevent the law’s implementation.

House File 766, passed in 2019 by the Republican-controlled Iowa House and Senate, excluded any Iowa organization that “provides or promotes abortion” from receiving federal dollars that support sex education and related services to Iowa youth.

Planned Parenthood of the Heartland and ACLU of Iowa challenged the law, filing a lawsuit shortly after Gov. Kim Reynolds signed the bill into law.

Polk County District Court issued a temporary injunction blocking the law, which was to go into effect July 1, allowing Planned Parenthood to continue providing sex education programming throughout the past year.

The governor’s office did not immediately respond to requests for comment on the ruling.

In its lawsuit, Planned Parenthood and ACLU argued that by blocking the abortion provider from the two federal grants — the Personal Responsibility Education Program (PREP) and the Community Adolescent Pregnancy Prevention (CAPP) — the law violated protections of free speech, due process and equal protection.

“The decision recognizes that the law blocking Planned Parenthood from receiving grants to provide this programming violated the constitutional requirement of equal protection,” ACLU of Iowa Legal Director Rita Bettis Austen said in a statement Thursday.

Though Planned Parenthood would be excluded, the law did allow “nonprofit health care delivery systems” to remain eligible for the federal funding, even if they are contracted with or are affiliated with an entity that performs abortions or maintains a facility where abortions are performed.

By doing so, the law effectively singles out Planned Parenthood, but allows other possible grant recipients to provide an array of abortion-related services, according to the court documents.

“The carved-out exception for the ‘nonprofit health care delivery system’ facilities undermines any rationale the State produces of not wanting to be affiliated with or provide funds to organizations that partake in any abortion-related activity,” Scott ruled. .

In fiscal year 2019, Planned Parenthood received about $265,000 through the federal grants, including $85,000 to offer PREP curriculum in Polk, Pottawattamie and Woodbury counties.

It was awarded $182,000 this year to offer CAPP curriculum in Linn County, as well as in Dallas, Des Moines, Jasper, Lee, Polk, Plymouth and Woodbury counties.

The grants are administered by the Iowa Department of Human Services and the Iowa Department of Public Health.

Planned Parenthood has provided sex education to students in 31 schools and 12 community-based youth organizations in Iowa using state-approved curriculum since 2005, according to a new release.

The focus has remained “on areas with the highest rates of unintended pregnancies and sexually-transmitted infections,” the news release said.

“Today’s decision ensures that teens and young adults across Iowa will continue to have access to medically accurate sex education programs, despite the narrow and reckless policies of anti-abortion lawmakers,” said Erin Davison-Rippey, executive director of Planned Parenthood North Central States.

A 10th wedding anniversary traditionally is celebrated with a gift of aluminum or tin.

For Sondy Daggett, her 10th year of marriage to Liz Hoskins was marked with a gift of Champagne and chocolate-covered strawberries shared through a window.

Employees at Bickford of Marion, the assisted living and memory care center where Hoskins is a resident, surprised the couple with the anniversary gift on May 1. Despite the current coronavirus-related mitigation practices, the staff had created a special moment for the couple, who have been partners for 24 years.

Daggett burst into tears as employees played their wedding song — Billy Joel’s “The Longest Time.”

“It just touched my soul,” Daggett said.

Across the state, moments like this are relegated through windows or over a phone call. As the novel coronavirus pandemic sweeps through the country, long-term care facilities have locked down in an effort to keep residents healthy, which means their families are no longer able to hug their loved ones, or sit with them in their rooms.

For many families, the feelings at such times this time are conflicted. Typical Mother’s Day celebrations have been placed on hold, and recent milestones have been missed by those living in long-term care facilities. Simple visits through windows feel distant.

“Those are the moments you remember and you miss,” said Daggett, recalling memories of visits to Bickford of Marion from Hoskins’s grandchildren and family gatherings during the holidays.

Hoskins, who has dementia, has been a resident at Bickford since August 2019.

“The pandemic has taken this away,” Daggett said.

But beyond this new dynamic with which family members are left to grapple, they also have the constant worry that their loved one could fall ill.

So far, Bickford of Marion has not seen any cases.

“Every time you read about another outbreak — whether it’s close to home or anywhere in the country — it brings home how fortunate we are so far,” said Matt Hoskins, Liz Hoskin’s son. “I can’t imagine the anxiety the residents and staff are having once it breaks through the wall.”

As of Friday, 29 long-term care facilities across the state, which includes skilled nursing facilities and senior living centers, among others — have reported outbreaks of COVID-19 among hundreds of their staff and residents.

As a result, for some Iowans, that fear has become a reality.

Ruth Brackett’s son Jamie Degner, a 38-year-old resident at Harmony House Health Care Center in Waterloo, tested positive for COVID-19 this past week.

Degner, who has severe autism and intellectual disabilities, has been a resident there since he was 15 years old.

More than 60 residents and staff have tested positive for COVID-19 at Harmony House, an intermediate care facility. It’s one of two long-term care facilities in Black Hawk County reporting an outbreak, defined as three or more positive tests among residents.

Degner received his test results on Tuesday. He’s had lower-than-normal oxygen levels, but otherwise has recorded his usual vital signs and has not experienced symptoms.

Brackett said it is “unbelievably difficult to not be able to go be with him through this.”

As with many facilities across the state, Harmony House closed its doors to visitors in early March, when the first cases of COVID-19 began being reported across Iowa and the nation. Brackett said her son’s cognitive abilities make it impossible for him to understand that she is unable to visit because she might make him sick, so the staff instead tell Degner his mom is “at work.”

While she’s optimistic he’ll improve, Brackett worries whether Degner’s virus would take a turn for the worse.

“It’s tough because I have to trust” the staff, Brackett said. “There’s nothing I can do, so I can’t spend a lot of time dwelling on what I might do differently.”

The families that spoke to The Gazette believe the leadership at long-term care facilities are doing what they can to keep its residents safe and healthy.

At Bickford of Marion, officials have taken the unique step of promising public transparency of possible COVID-19 cases in its facility. On the website of every Bickford location is a feature recording the number of residents who have tested positive for COVID-19.

“Whether it’s COVID-19 or not, we want to be transparent with families about their loved ones’ care,” Bickford of Marion Executive Director Jacobi Feckers said. “I don’t know why other nursing homes haven’t taken that step because I haven’t spoken to other facilities, but I’m thankful that’s the route we’ve taken.”

It’s not just families who are placing their trust in management. Ron Moore is an independent living resident at Cottage Grove Place, one of the largest senior living centers in Cedar Rapids that has reported an outbreak of COVID-19 this past week.

According to the latest data from public health officials, five residents and staff there have tested positive.

The outbreak originated in the skilled nursing unit, and officials said they are working to ensure the virus doesn’t spread to the assisted-living and independent-living portions of the facility. They restricted movement between the facilities and conduct frequent temperature checks of staff.

So far, the general feeling among residents at Cottage Grove Place’s independent-living housing is that management has “done a good job” of controlling exposure.

“The feelings of the residents here are positive,” Moore said. “They appreciate what management has done to protect us.”

Still, life looks much differently at Cottage Grove Place. Moore said his schedule typically is packed with weekly book clubs and coffees with friends. Now he and his wife take walks, or try to connect with friends over email.

“I’ve found (residents) are not depressed at this time,” he said. “But in the future, if this goes on for many months? My prediction is yes, depression will be a serious thing.”

Local senior living centers have come up with unique ways to allow visitors to see their loved ones. Gina Hausknecht, a 55-year-old Iowa City resident, was able to see her mother in person for the first time in weeks after her assisted-living home, Oaknoll Retirement Community in Iowa City, created a “drive up” visit option this past weekend.

While Hausknecht sat in the car, she was able to speak with her mother, 93-year-old Ellen Hausknecht, for an hour outside the facility. Before this, it had been emotionally difficult for Hausknecht not to see her mom weekly as she usually does

“It sunk in that I don’t know when I’m going to see my mom again, and that felt really terrible,” Hausknecht previously told The Gazette.

Hausknecht said she hopes to take this year’s Mother’s Day as an opportunity to do something special, particularly given the difficult past few weeks.

“Our family isn’t super-big on these kinds of holidays but we do like to acknowledge them, and this year it feels important to take hold of any opportunity to celebrate,” she said.

Other facilities, including Bickford of Marion, also have eased restrictions on sending food and gifts to residents in time for Mother’s Day. Matt Hoskins, Liz’s Hoskins’ son, said the family’s usual Mother’s Day plans are impossible this year, so they hope to send Liz’s Hoskins artwork from her grandchildren along with other gifts.

Brackett, who will be apart from her son Degner this year, said she hadn’t planned anything for the holiday. She looks forward to her first in-person visit with him after the pandemic, when she will bring his favorite meal from McDonald’s and a new deck of Phase 10 cards.

Despite the feelings of being separated, their wedding anniversary on May 1 likely is something Daggett will cherish, she said. With Daggett acting as Hoskins caregiver since her dementia diagnosis in 2016, their wedding anniversary has been something the couple hasn’t celebrated in a significant way in some time, she said.

But that worry still creeps in the back of her mind. Daggett said she’s trying to remain “as confident as anyone can at this point.”

“I learned a long time ago you can’t worry about what you can’t control,” Daggett said. “But does that mean I still wake up at 2 in the morning worried about it? Of course I do.”

The two-dimensional directed spanning forest (DSF) introduced by Baccelli and Bordenave is a planar directed forest whose vertex set is given by a homogeneous Poisson point process $mathcal{N}$ on $mathbb{R}^2$. If the DSF has direction $-e_y$, the ancestor $h(u)$ of a vertex $u in mathcal{N}$ is the nearest Poisson point (in the $L_2$ distance) having strictly larger $y$-coordinate. This construction induces complex geometrical dependencies. In this paper we show that the collection of DSF paths, properly scaled, converges in distribution to the Brownian web (BW). This verifies a conjecture made by Baccelli and Bordenave in 2007.

We use Ricci flow to obtain a local bi-Holder correspondence between Ricci limit spaces in three dimensions and smooth manifolds. This is more than a complete resolution of the three-dimensional case of the conjecture of Anderson-Cheeger-Colding-Tian, describing how Ricci limit spaces in three dimensions must be homeomorphic to manifolds, and we obtain this in the most general, locally non-collapsed case. The proofs build on results and ideas from recent papers of Hochard and the current authors.

The paper proves the Riemann Hypothesis.

The Baumslag Solitar group $BS(2,3)$, is a so-called non-Hopfian group, meaning that it has an epimorphism $phi$ onto itself, that is not injective. In particular this is equivalent to saying that $BS(2,3)$ has a quotient that is isomorphic to itself. As a consequence the Cayley graph of $BS(2,3)$ has a quotient that is isomorphic to itself up to change of generators. We describe this quotient on the graph-level and take a closer look at the most common epimorphism $phi$. We show its kernel is a free group of infinite rank with an explicit set of generators.

In this work, the generalized $N$-component Fokas-Lenells(FL) equations, which have been studied by Guo and Ling (2012 J. Math. Phys. 53 (7) 073506) for $N=2$, are first investigated via Riemann-Hilbert(RH) approach. The main purpose of this is to study the soliton solutions of the coupled Fokas-Lenells(FL) equations for any positive integer $N$, which have more complex linear relationship than the analogues reported before. We first analyze the spectral analysis of the Lax pair associated with a $(N+1) imes (N+1)$ matrix spectral problem for the $N$-component FL equations. Then, a kind of RH problem is successfully formulated. By introducing the special conditions of irregularity and reflectionless case, the $N$-soliton solution formula of the equations are derived through solving the corresponding RH problem. Furthermore, take $N=2,3$ and $4$ for examples, the localized structures and dynamic propagation behavior of their soliton solutions and their interactions are discussed by some graphical analysis.

In this paper, we characterize a mixed graph $F$ which contains $k$ edge and arc disjoint spanning mixed arborescences $F_{1}, ldots, F_{k}$, such that for each $v in V(F)$, the cardinality of ${i in [k]: v ext{ is the root of } F_{i}}$ lies in some prescribed interval. This generalizes both Nash-Williams and Tutte's theorem on spanning tree packing for undirected graphs and the previous characterization on digraphs which was given by Cai [in: Arc-disjoint arborescences of digraphs, J. Graph Theory 7(2) (1983), 235-240] and Frank [in: On disjoint trees and arborescences, Algebraic Methods in Graph Theory, Colloquia Mathematica Soc. J. Bolyai, Vol. 25 (North-Holland, Amsterdam) (1978), 159-169].

Input transformation based defense strategies fall short in defending against strong adversarial attacks. Some successful defenses adopt approaches that either increase the randomness within the applied transformations, or make the defense computationally intensive, making it substantially more challenging for the attacker. However, it limits the applicability of such defenses as a pre-processing step, similar to computationally heavy approaches that use retraining and network modifications to achieve robustness to perturbations. In this work, we propose a defense strategy that applies random image corruptions to the input image alone, constructs a self-correlation based subspace followed by a projection operation to suppress the adversarial perturbation. Due to its simplicity, the proposed defense is computationally efficient as compared to the state-of-the-art, and yet can withstand huge perturbations. Further, we develop proximity relationships between the projection operator of a clean image and of its adversarially perturbed version, via bounds relating geodesic distance on the Grassmannian to matrix Frobenius norms. We empirically show that our strategy is complementary to other weak defenses like JPEG compression and can be seamlessly integrated with them to create a stronger defense. We present extensive experiments on the ImageNet dataset across four different models namely InceptionV3, ResNet50, VGG16 and MobileNet models with perturbation magnitude set to {epsilon} = 16. Unlike state-of-the-art approaches, even without any retraining, the proposed strategy achieves an absolute improvement of ~ 4.5% in defense accuracy on ImageNet.

Robots operating in household environments must find objects on shelves, under tables, and in cupboards. Previous work often formulate the object search problem as a POMDP (Partially Observable Markov Decision Process), yet constrain the search space in 2D. We propose a new approach that enables the robot to efficiently search for objects in 3D, taking occlusions into account. We model the problem as an object-oriented POMDP, where the robot receives a volumetric observation from a viewing frustum and must produce a policy to efficiently search for objects. To address the challenge of large state and observation spaces, we first propose a per-voxel observation model which drastically reduces the observation size necessary for planning. Then, we present a novel octree-based belief representation which captures beliefs at different resolutions and supports efficient exact belief update. Finally, we design an online multi-resolution planning algorithm that leverages the resolution layers in the octree structure as levels of abstractions to the original POMDP problem. Our evaluation in a simulated 3D domain shows that, as the problem scales, our approach significantly outperforms baselines without resolution hierarchy by 25%-35% in cumulative reward. We demonstrate the practicality of our approach on a torso-actuated mobile robot searching for objects in areas of a cluttered lab environment where objects appear on surfaces at different heights.

With the increase in use of Unmanned Aerial Vehicles (UAVs)/drones, it is important to detect and identify causes of failure in real time for proper recovery from a potential crash-like scenario or post incident forensics analysis. The cause of crash could be either a fault in the sensor/actuator system, a physical damage/attack, or a cyber attack on the drone's software. In this paper, we propose novel architectures based on deep Convolutional and Long Short-Term Memory Neural Networks (CNNs and LSTMs) to detect (via Autoencoder) and classify drone mis-operations based on sensor data. The proposed architectures are able to learn high-level features automatically from the raw sensor data and learn the spatial and temporal dynamics in the sensor data. We validate the proposed deep-learning architectures via simulations and experiments on a real drone. Empirical results show that our solution is able to detect with over 90% accuracy and classify various types of drone mis-operations (with about 99% accuracy (simulation data) and upto 88% accuracy (experimental data)).

We consider a fair division setting where indivisible items are allocated to agents. Each agent in the setting has strictly negative, zero or strictly positive utility for each item. We, thus, make a distinction between items that are good for some agents and bad for other agents (i.e. mixed), good for everyone (i.e. goods) or bad for everyone (i.e. bads). For this model, we study axiomatic concepts of allocations such as jealousy-freeness up to one item, envy-freeness up to one item and Pareto-optimality. We obtain many new possibility and impossibility results in regard to combinations of these properties. We also investigate new computational tasks related to such combinations. Thus, we advance the state-of-the-art in fair division of mixed manna.

Uncertain dynamic obstacles, such as pedestrians or vehicles, pose a major challenge for optimal robot navigation with safety guarantees. Previous work on motion planning has followed two main strategies to provide a safe bound on an obstacle's space: a polyhedron, such as a cuboid, or a nonlinear differentiable surface, such as an ellipsoid. The former approach relies on disjunctive programming, which has a relatively high computational cost that grows exponentially with the number of obstacles. The latter approach needs to be linearized locally to find a tractable evaluation of the chance constraints, which dramatically reduces the remaining free space and leads to over-conservative trajectories or even unfeasibility. In this work, we present a hybrid approach that eludes the pitfalls of both strategies while maintaining the original safety guarantees. The key idea consists in obtaining a safe differentiable approximation for the disjunctive chance constraints bounding the obstacles. The resulting nonlinear optimization problem is free of chance constraint linearization and disjunctive programming, and therefore, it can be efficiently solved to meet fast real-time requirements with multiple obstacles. We validate our approach through mathematical proof, simulation and real experiments with an aerial robot using nonlinear model predictive control to avoid pedestrians.

High-resolution remote sensing images (HRRSIs) contain substantial ground object information, such as texture, shape, and spatial location. Semantic segmentation, which is an important task for element extraction, has been widely used in processing mass HRRSIs. However, HRRSIs often exhibit large intraclass variance and small interclass variance due to the diversity and complexity of ground objects, thereby bringing great challenges to a semantic segmentation task. In this paper, we propose a new end-to-end semantic segmentation network, which integrates lightweight spatial and channel attention modules that can refine features adaptively. We compare our method with several classic methods on the ISPRS Vaihingen and Potsdam datasets. Experimental results show that our method can achieve better semantic segmentation results. The source codes are available at https://github.com/lehaifeng/SCAttNet.

Recent works imply that the channel pruning can be regarded as searching optimal sub-structure from unpruned networks.

However, existing works based on this observation require training and evaluating a large number of structures, which limits their application.

In this paper, we propose a novel differentiable method for channel pruning, named Differentiable Markov Channel Pruning (DMCP), to efficiently search the optimal sub-structure.

Our method is differentiable and can be directly optimized by gradient descent with respect to standard task loss and budget regularization (e.g. FLOPs constraint).

In DMCP, we model the channel pruning as a Markov process, in which each state represents for retaining the corresponding channel during pruning, and transitions between states denote the pruning process.

In the end, our method is able to implicitly select the proper number of channels in each layer by the Markov process with optimized transitions. To validate the effectiveness of our method, we perform extensive experiments on Imagenet with ResNet and MobilenetV2.

Results show our method can achieve consistent improvement than state-of-the-art pruning methods in various FLOPs settings. The code is available at https://github.com/zx55/dmcp

The paper develops a robotic manipulation system to treat the pressing needs for handling a large number of test tubes in clinical examination and replace or reduce human labor. It presents the technical details of the system, which separates and arranges test tubes in racks with the help of 3D vision and artificial intelligence (AI) reasoning/planning. The developed system only requires a person to put a rack with mixed and non-arranged tubes in front of a robot. The robot autonomously performs recognition, reasoning, planning, manipulation, etc., and returns a rack with separated and arranged tubes. The system is simple-to-use, and there are no requests for expert knowledge in robotics. We expect such a system to play an important role in helping managing public health and hope similar systems could be extended to other clinical manipulation like handling mixers and pipettes in the future.

We analyze the computational complexity of motion planning through local "input/output" gadgets with separate entrances and exits, and a subset of allowed traversals from entrances to exits, each of which changes the state of the gadget and thereby the allowed traversals. We study such gadgets in the 0-, 1-, and 2-player settings, in particular extending past motion-planning-through-gadgets work to 0-player games for the first time, by considering "branchless" connections between gadgets that route every gadget's exit to a unique gadget's entrance. Our complexity results include containment in L, NL, P, NP, and PSPACE; as well as hardness for NL, P, NP, and PSPACE. We apply these results to show PSPACE-completeness for certain mechanics in Factorio, [the Sequence], and a restricted version of Trainyard, improving prior results. This work strengthens prior results on switching graphs and reachability switching games.

Embodiments of the disclosure include a method for partitioning a deterministic finite automaton (DFA) into a plurality of groups. The method includes selecting, with a processing device, a subset of the plurality of states and mapping each state of the subset onto a group of the plurality of groups by assigning one or more transition rules associated with each state to a rule line of the group, wherein each rule line is assigned at most two transition rules and an extended address associated with one of the at most two transition rules. The method also includes iteratively processing each state of the subset mapped onto the group by removing the extended address from each rule line in the group with transition rules referring to a current state if the transition rules in the rule line branch within the group.

Embodiments of the present disclosure describe device, methods, computer-readable media and system configurations for decoding codewords using a side channel. In various embodiments, a memory controller may be configured to determine that m of n die of non-volatile memory (“NVM”) have failed iterative decoding. In various embodiments, the memory controller may be further configured to generate a side channel from n-m non-failed die and the m failed die other than a first failed die. In various embodiments, the memory controller may be further configured to reconstruct, using iterative decoding, a codeword stored on the first failed die of the m failed die based on the generated side channel and on soft input to an attempt to iteratively decode data stored on the first failed die. In various embodiments, the iterative decoding may include low-density parity-check decoding. Other embodiments may be described and/or claimed.

Various embodiments of the present invention provide systems and methods for data processing. As an example, a data processing circuit is disclosed that includes a data detector circuit. The data detector circuit includes an anti-causal noise predictive filter circuit and a data detection circuit. In some cases, the anti-causal noise predictive filter circuit is operable to apply noise predictive filtering to a detector input to yield a filtered output, and the data detection circuit is operable to apply a data detection algorithm to the filtered output derived from the anti-causal noise predictive filter circuit.

Certain embodiments of the present disclosure are directed to a baseboard management controller (BMC) that includes a PCI express (PCIe) interface controller configured to provide access to a PCIe channel over a PCIe link, and firmware. The firmware includes a PCIe module being configured to access the PCIe channel through the PCIe interface controller and registered as a PCIe function. A software stack of the BMC communicates, through the PCIe module, with a PCIe device over the PCIe channel.

A navigation system having a central device which uses a link shape compression unit to compress information of altitude changes of a road link obtained from a three-dimensional road map, and calculates a geometry parameter based on variation of energy of a vehicle travelling on the road link. An on-board terminal device estimates the vehicle's average travelling pattern by using a travel-pattern-estimation unit based on the geometry parameter calculated by the central device, a link-travelling time estimated from statistically-stored traffic information, and a link length. The on-board terminal device further calculates fuel consumption of the vehicle travelling on each road link based on the estimated travelling pattern and parameters of the vehicle by using a fuel-consumption calculation unit, and then, searches a fuel-efficient route by using the fuel consumption as a link cost. The on-board terminal device has a vehicle-type selector for selecting a type of the vehicle.
