I was happy to read Joe Coffey’s article in Sunday’s paper (“The birth of news in Linn County”) about the history of newspapers in Linn County. But I was disappointed that Mr. Coffey did not include mention of the Metro Libraries’ historical newspaper databases. All of the papers mentioned and pictured in his article (and many more!) are available in scanned, full-text, searchable versions, through the websites of the Cedar Rapids and Marion Public Libraries. There is no charge to browse or search these delightful old editions, and in fact, you don’t even need a library card.

I encourage anyone with an interest in local history, or just with a little time on your hands, to look at some of these old newspapers. It’s a delightful adventure to read about lives in other times.

Chet Culver really should have known better.

Iowa’s former Democratic governor wrote a letter to current Republican Gov. Kim Reynolds decrying her administration’s declaration that workers who refuse to return to jobs amid COVID-19 fears would be denied unemployment benefits. He was among many who questioned whether Reynolds’ policy is even lawful, considering that unemployment rules allow Iowans to claim benefits for unsafe, intolerable or detrimental working conditions.

“Any such ill-conceived scheme that deprives them of choice and forces those hardworking, yet vulnerable, employees to report to unsafe workplace environments, while the positive incidences of COVID-19 infection are on the rise, is not merely penny-wise and pound-foolish — it is just plain wrong,” Culver argued.

But Culver should have known any overture for the rights of workers during the pandemic would fall on deaf ears. We learned Tuesday that more than 1,600 workers at four meatpacking plants tested positive for the virus. Reynolds continues insisting companies such as Tyson, with more than 1,300 cases at three facilities, are doing all they can to protect workers. In one Tyson facility at Perry, 58 percent of its employees contracted the virus.

Culver lost in 2010 to the Branstad-Reynolds ticket, a team that would go on to gut collective bargaining for public employees and make it far more difficult for injured workers to get compensation, among other greatest hits composed by its big business allies.

And Culver was bounced from office after issuing bonded debt to help Iowa communities, including Cedar Rapids, recover from natural disasters of 2008. Republicans dubbed him “Big Debt Chet” and decried his mismanagement of a crisis.

Strong management, apparently, is Reynolds’ decision to partially reopen 77 counties even as COVID-19 case numbers grow and deaths mount, and before ramped up testing and modeling provide critical information on the scope of the virus.

On Monday Reynolds received a lofty “A” grade from FreedomWorks and the Committee to Unleash Prosperity. Reynolds appeared on a conference call sponsored by the groups to talk about her strategy for reopening Iowa.

FreedomWorks and the Committee to Unleash Prosperity are conservative groups playing a key role in organizing “liberation” protests in Wisconsin, Oklahoma and elsewhere. FreedomWorks, with roots in the Tea Party movement, has been mobilizing local protesters and organizing events, according to The New York Times. It’s also conducting tracking polls in swing congressional districts and sharing data with presidential advisers and congressional staff.

“This isn’t political, and it shouldn’t be for anybody,” Reynolds told reporters this week when asked about her virus response.

FreedomWorks is among 24 groups who sent a letter to the president in April urging him to waive the Renewable Fuel Standard for the rest of the year due to pandemic concerns, potentially freeing Iowa farmers from more of their already scarce income.

So step aside Big Debt Chet. We’re unleashing prosperity. Even if workers get trampled.

Iowa State University graduates who celebrated commencement Friday saw lots of caps and gowns, red-and-gold confetti and arenas packed with friends and family.

But none of those images were from this year — which now is defined by the novel coronavirus that has forced education online and put an end to large gatherings like graduation ceremonies.

Appearing in front of a red ISU screen Friday, College of Agriculture and Life Sciences Dean Daniel J. Robison addressed graduates like he usually would at commencement — but this time in a recorded message acknowledging the unprecedented circumstances keeping them apart.

“This year, because of the COVID crisis, we are unfortunately not all together for this happy occasion,” he said, pushing forward in a motivational tone by quoting famed ISU alumnus George Washington Carver.

“When you can do the common things in life in an uncommon way, you will command the attention of the world,” Robison said, citing Carver.

About 12,000 graduates across Iowa’s public universities this month are doing exactly that — capping their collegiate careers with never-before-attempted online-only commencement ceremonies, with each campus and their respective colleges attempting a variety of virtual celebration methods.

ISU and the University of Iowa are attempting some form of socially-distanced livestreamed convocation with countdown clocks and virtual confetti. All three campuses including the University of Northern Iowa have posted online recorded messages, videos and slides acknowledging individual graduates.

Some slides include photos, thank-yous, quotes and student plans for after graduation.

UNI, which didn’t try any form of a live virtual ceremony, instead created a graduation website that went live Thursday. That site hosts an array of recorded video messages — including one from UNI President Mark Nook who, standing alone behind a podium on campus clad in traditional academic regalia, recognized his campus’ 1,500-some spring graduates and their unusual challenges.

“We know the loss you feel in not being able to be on campus to celebrate this time with your friends, faculty and staff,” Nook said. “To walk around campus in your robe and to take those pictures with friends and family members … The loss is felt by many of us as well.”

He reminded those listening that this spring’s UNI graduates — like those at the UI and ISU — can participate in an upcoming in-person commencement ceremony.

And although students were allowed to return caps and gowns they ordered for their canceled walks across the stage, some kept them as keepsakes. The campuses offered other tokens of remembrance as well, including “CYlebration” gift packages ISU sent to graduates in April stuffed with a souvenir tassel, diploma cover, and streamer tube — to make up for the confetti that won’t be falling on graduation caps from the Hilton Coliseum rafters.

In addition to the recorded messages from 17 UI leaders — including President Bruce Harreld — the campus solicited parent messages, which will be included in the live virtual ceremonies.

To date, about 3,100 of the more than 5,400 UI graduates have RSVP’d to participate in the ceremony, which spokeswoman Anne Bassett said is a required affirmation from the students to have their names read.

“Students do not have to sign up to watch,” she said. “So there’s no way at this time to predict how many will do so.”

Despite the historic nature of the first online-only commencement ceremonies — forever bonding distanced graduates through the shared experience — UI graduate Omar Khodor, 22, said it’s a club he would have liked to avoid.

“I’d definitely prefer not to be part of that group,” the environmental science major said, sharing disappointment over the education, experiences and celebrations he lost to the pandemic.

“A lot of students like myself, we’re upset, but we’re not really allowed to be upset given the circumstances,” Khodor said. “You have this sense that something is unfair, that something has been taken from you. But you can’t be mad about it at all.”

Life is too short to dwell on what could have been or what should have been — which sort of captures graduate Dawn Hales’ motivation to get an ISU degree.

The 63-year-old Ames grandmother calls herself the “oldest BSN Iowa State grad ever.”

“It’s the truth, because we’re only the second cohort to graduate,” Hales said. “I’ll probably be the oldest for a while.”

ISU began offering a Bachelor of Science in nursing degree in fall 2018 for registered nurses hoping to advance their careers — like Hales, who spent years in nursing before becoming director of nursing at Accura Healthcare, a skilled nursing and rehabilitation center in Ames.

In addition to wanting more education, Hales said, she felt like the “odd man out” in her red-and-gold family — with her husband, three sons and their wives all earning ISU degrees. She earned an associate degree and became a registered nurse with community college training.

“I was director of nursing at different facilities, but I did not have a four-year degree,” she said. “I always wanted to get my BSN.”

So in January 2019, she started full-time toward her three-semester pursuit of a BSN — even as she continued working. And her education took a relevant and important turn when COVID-19 arrived.

“My capstone project was infection control,” she said, noting her focus later sharpened to “infection control and crisis management” — perfect timing to fight the coronavirus, which has hit long-term care facilities particularly hard.

“We were hyper vigilant,” Hales said of her facility, which has yet to report a case of COVID-19. “I think we were probably one of the first facilities that pretty much shut down and started assessing our staff when they would come in.”

Hales said she was eager to walk in her first university graduation and was planning antics for it with her 10-year-old granddaughter.

“We were trying to think, should I dance across the stage?” Hales said. “Or would I grab a walker and act like an old lady going across the stage?

“She was trying to teach me to do this ‘dab’ move,” Hales said. “I said, ‘Honey, I cannot figure that out.’”

In the end, Hales watched the celebration online instead. She did, however, get a personalized license plate that reads, “RN2BSN.”

Coming from a family-run dairy farm in Jerome, Idaho, EllieMae Millenkamp, 22, is the first in her family to graduate college.

Although music is her passion, Millenkamp long expected to study at an agriculture school — but Colorado State was her original choice.

Then, while visiting family in Iowa during a cousin’s visit to ISU, she fell in love with the Ames campus and recalibrated her academic path.

While at ISU, the musical Millenkamp began writing more songs and performing more online, which led to in-person shows and a local band.

And then, during her junior year, a talent scout reached out to invite her to participate in an audition for NBC’s “The Voice.” That went well and Millenkamp, in the summer before her senior year, moved to Los Angeles and made it onto the show.

She achieved second-round status before being bumped, but the experience offered her lifelong friendships and connections and invigorated her musical pursuits — which have been slowed by COVID-19. Shows have been canceled in now idled bars.

Millenkamp went back to Idaho to be with her family, like thousands of her peers also did with their families, when the ISU campus shut down.

After graduation she plans on returning and working the family farm again until her musical career has the chance to regain momentum.

But she recently returned to Ames for finals. And she and some friends, also in town, plan to celebrate graduation, even if not with an official cap and gown.

“We’ll probably have a bonfire and all hang out,” she said. “We’ll celebrate in our own way.”

Most college seniors nearing graduation get to spend their academic hours focusing on their major and interests, wrapping their four or sometimes five years with passion projects and capstone experiences.

That was Omar Khodor’s plan — with lab-based DNA sequencing on tap, along with a geology trip and policy proposal he planned to present to the Iowa Legislature. But all that got canceled — and even some requirements were waived since COVID-19 made them impossible.

“There were still a lot of a lot of things to wrap up,” he said. “A lot of things I was looking forward to.”

He’s ending the year with just three classes to finish and “absolutely” would have preferred to have a fuller plate.

But Khodor’s academic career isn’t over. He’s planning to attend law school in the fall at the University of Pennsylvania, where he’ll pursue environmental law. But this spring has diminished his enthusiasm, with the question lingering of whether in-person courses will return to campus soon.

If they don’t, he’s still leaning toward enrolling — in part — because of all the work that goes into applying and getting accepted, which he’s already done.

“But online classes are definitely less fulfilling, less motivating. You feel like you learn less,” he said. “So it will kind of be a tossup. There’ll be some trade-offs involved in what I would gain versus what I would be paying for such an expensive endeavor like law school.”

As for missing a traditional college commencement, Khodor said he will, even though he plans to participate in the virtual alternative.

“Before it got canceled, I didn’t think that I was looking forward to it as much as I actually was,” he said.

Not so much for the pomp and circumstance, but for the closure, which none of the seniors got this year. When the universities announced no one would return to campus this semester, students were away on spring break.

They had already experienced their last in-person class, their last after-class drink, their last cram session, their last study group, their last lecture, their last Iowa Memorial Union lunch — and they didn’t even know it.

“So many of us, we won’t have closure, and that can kind of be a difficult thing,” he said.

It has been a month since we launched our first online workshop and, to be honest, we really didn’t know whether people would enjoy them — or if we would enjoy running them. It was an experiment, but one we are so glad we jumped into! I spoke about the experience of taking my workshop online on a recent episode of the Smashing podcast. As a speaker, I had expected it to feel very much like I was presenting into the empty air, with no immediate feedback and expressions to work from.

In these strange times when everything is connected, it’s too easy to feel lonely and detached. Yes, everybody is just one message away, but there is always something in the way — deadlines to meet, Slack messages to reply, or urgent PRs to review. Connections need time and space to grow, just like learning, and conferences are a great way to find that time and that space. In fact, with SmashingConfs, we’ve always been trying to create such friendly and inclusive spaces.

One proves the existence and uniqueness of a generalized (mild) solution for the nonlinear Fokker--Planck equation (FPE) egin{align*} &u_t-Delta (eta(u))+{mathrm{ div}}(D(x)b(u)u)=0, quad tgeq0, xinmathbb{R}^d, d e2, \ &u(0,cdot)=u_0,mbox{in }mathbb{R}^d, end{align*} where $u_0in L^1(mathbb{R}^d)$, $etain C^2(mathbb{R})$ is a nondecreasing function, $bin C^1$, bounded, $bgeq 0$, $Din(L^2cap L^infty)(mathbb{R}^d;mathbb{R}^d)$ with ${ m div}, Din L^infty(mathbb{R}^d)$, and ${ m div},Dgeq0$, $eta$ strictly increasing, if $b$ is not constant. Moreover, $t o u(t,u_0)$ is a semigroup of contractions in $L^1(mathbb{R}^d)$, which leaves invariant the set of probability density functions in $mathbb{R}^d$. If ${ m div},Dgeq0$, $eta'(r)geq a|r|^{alpha-1}$, and $|eta(r)|leq C r^alpha$, $alphageq1,$ $alpha>frac{d-2}d$, $dgeq3$, then $|u(t)|_{L^infty}le Ct^{-frac d{d+(alpha-1)d}} |u_0|^{frac2{2+(m-1)d}},$ $t>0$, and the existence extends to initial data $u_0$ in the space $mathcal{M}_b$ of bounded measures in $mathbb{R}^d$. The solution map $mumapsto S(t)mu$, $tgeq0$, is a Lipschitz contractions on $mathcal{M}_b$ and weakly continuous in $tin[0,infty)$. As a consequence for arbitrary initial laws, we obtain weak solutions to a class of McKean-Vlasov SDEs with coefficients which have singular dependence on the time marginal laws.

We consider a nonlinear Dirichlet problem driven by a nonhomogeneous differential operator plus an indefinite potential. In the reaction we have the competing effects of a singular term and of concave and convex nonlinearities. In this paper the concave term is parametric. We prove a bifurcation-type theorem describing the changes in the set of positive solutions as the positive parameter $lambda$ varies. This work continues our research published in arXiv:2004.12583, where $xi equiv 0 $ and in the reaction the parametric term is the singular one.

In this paper, we mainly establish the existence and uniqueness theorem for solutions of the exterior Dirichlet problem for a class of fully nonlinear second-order elliptic equations related to the eigenvalues of the Hessian, with prescribed generalized symmetric asymptotic behavior at infinity. Moreover, we give some new results for the Hessian equations, Hessian quotient equations and the special Lagrangian equations, which have been studied previously.

This paper deals with an optimal control problem associated to the Kuramoto model describing the dynamical behavior of a network of coupled oscillators. Our aim is to design a suitable control function allowing us to steer the system to a synchronized configuration in which all the oscillators are aligned on the same phase. This control is computed via the minimization of a given cost functional associated with the dynamics considered. For this minimization, we propose a novel approach based on the combination of a standard Gradient Descent (GD) methodology with the recently-developed Random Batch Method (RBM) for the efficient numerical approximation of collective dynamics. Our simulations show that the employment of RBM improves the performances of the GD algorithm, reducing the computational complexity of the minimization process and allowing for a more efficient control calculation.

This paper is devoted to the study of the singularity phenomenon of timelike extremal hypersurfaces in Minkowski spacetime $mathbb{R}^{1+3}$. We find that there are two explicit lightlike self-similar solutions to a graph representation of timelike extremal hypersurfaces in Minkowski spacetime $mathbb{R}^{1+3}$, the geometry of them are two spheres. The linear mode unstable of those lightlike self-similar solutions for the radially symmetric membranes equation is given. After that, we show those self-similar solutions of the radially symmetric membranes equation are nonlinearly stable inside a strictly proper subset of the backward lightcone. This means that the dynamical behavior of those two spheres is as attractors. Meanwhile, we overcome the double roots case (the theorem of Poincar'{e} can't be used) in solving the difference equation by construction of a Newton's polygon when we carry out the analysis of spectrum for the linear operator.

We study a class of fourth order nonlinear parabolic equations which include the thin-film equation and the quantum drift-diffusion model as special cases. We investigate these equations by first developing functional inequalities of the type $ int_Omega u^{2gamma-alpha-eta}Delta u^alphaDelta u^eta dx geq cint_Omega|Delta u^gamma |^2dx $, which seem to be of interest on their own right.

A reaction-diffusion model was developed describing the spread of the COVID-19 virus considering the mean daily movement of susceptible, exposed and asymptomatic individuals. The model was calibrated using data on the confirmed infection and death from France as well as their initial spatial distribution. First, the system of partial differential equations is studied, then the basic reproduction number, R0 is derived. Second, numerical simulations, based on a combination of level-set and finite differences, shown the spatial spread of COVID-19 from March 16 to June 16. Finally, scenarios of unlockdown are compared according to variation of distancing, or partially spatial lockdown.

We consider two special cases of the connection problem for the second Painlev'e equation (PII) using the method of uniform asymptotics proposed by Bassom et al.. We give a classification of the real solutions of PII on the negative (positive) real axis with respect to their initial data. By product, a rigorous proof of a property associate with the nonlinear eigenvalue problem of PII on the real axis, recently revealed by Bender and Komijani, is given by deriving the asymptotic behavior of the Stokes multipliers.

The main goal of this paper is to achieve a parametrization of the solution set of the truncated matricial Hausdorff moment problem in the non-degenerate and degenerate situation. We treat the even and the odd cases simultaneously. Our approach is based on Schur analysis methods. More precisely, we use two interrelated versions of Schur-type algorithms, namely an algebraic one and a function-theoretic one. The algebraic version, worked out in our former paper arXiv:1908.05115, is an algorithm which is applied to finite or infinite sequences of complex matrices. The construction and discussion of the function-theoretic version is a central theme of this paper. This leads us to a complete description via Stieltjes transform of the solution set of the moment problem under consideration. Furthermore, we discuss special solutions in detail.

The main aim of this paper is to detect dynamical properties of the Gy"orgyi-Field model of the Belousov-Zhabotinsky chemical reaction. The corresponding three-variable model given as a set of nonlinear ordinary differential equations depends on one parameter, the flow rate. As certain values of this parameter can give rise to chaos, the analysis was performed in order to identify different dynamics regimes. Dynamical properties were qualified and quantified using classical and also new techniques. Namely, phase portraits, bifurcation diagrams, the Fourier spectra analysis, the 0-1 test for chaos, and approximate entropy. The correlation between approximate entropy and the 0-1 test for chaos was observed and described in detail. Moreover, the three-stage system of nested subintervals of flow rates, for which in every level the 0-1 test for chaos and approximate entropy was computed, is showing the same pattern. The study leads to an open problem whether the set of flow rate parameters has Cantor like structure.

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.

Recent single image unsupervised representation learning techniques show remarkable success on a variety of tasks. The basic principle in these works is instance discrimination: learning to differentiate between two augmented versions of the same image and a large batch of unrelated images. Networks learn to ignore the augmentation noise and extract semantically meaningful representations. Prior work uses artificial data augmentation techniques such as cropping, and color jitter which can only affect the image in superficial ways and are not aligned with how objects actually change e.g. occlusion, deformation, viewpoint change. In this paper, we argue that videos offer this natural augmentation for free. Videos can provide entirely new views of objects, show deformation, and even connect semantically similar but visually distinct concepts. We propose Video Noise Contrastive Estimation, a method for using unlabeled video to learn strong, transferable single image representations. We demonstrate improvements over recent unsupervised single image techniques, as well as over fully supervised ImageNet pretraining, across a variety of temporal and non-temporal tasks.

The scheduling model is motivated by manufacturing processes of individualized medicaments, which are used in modern medicine to treat some serious illnesses. We provide two different online algorithms, proving also lower bounds for the offline problem to compute their competitive ratios. The first algorithm is an easy-to-implement, general local scheduling heuristic. It is 2-competitive for PFFBs with an arbitrary number of stages and for several natural scheduling objectives. We also show that for total/average flow time, no deterministic algorithm with better competitive ratio exists. For the special case with two stages and the makespan or total completion time objective, we describe an improved algorithm that achieves the best possible competitive ratio $varphi=frac{1+sqrt{5}}{2}$, the golden ratio. All our results also hold for proportionate (non-flexible) flow shops of batching machines (PFB) for which this is also the first paper to study online algorithms.

This paper considers a convex optimization problem with cost and constraints that evolve over time. The function to be minimized is strongly convex and possibly non-differentiable, and variables are coupled through linear constraints.In this setting, the paper proposes an online algorithm based on the alternating direction method of multipliers(ADMM), to track the optimal solution trajectory of the time-varying problem; in particular, the proposed algorithm consists of a primal proximal gradient descent step and an appropriately perturbed dual ascent step. The paper derives tracking results, asymptotic bounds, and linear convergence results. The proposed algorithm is then specialized to a multi-area power grid optimization problem, and our numerical results verify the desired properties.

We establish versions of Conley's (i) fundamental theorem and (ii) decomposition theorem for a broad class of hybrid dynamical systems. The hybrid version of (i) asserts that a globally-defined "hybrid complete Lyapunov function" exists for every hybrid system in this class. Motivated by mechanics and control settings where physical or engineered events cause abrupt changes in a system's governing dynamics, our results apply to a large class of Lagrangian hybrid systems (with impacts) studied extensively in the robotics literature. Viewed formally, these results generalize those of Conley and Franks for continuous-time and discrete-time dynamical systems, respectively, on metric spaces. However, we furnish specific examples illustrating how our statement of sufficient conditions represents merely an early step in the longer project of establishing what formal assumptions can and cannot endow hybrid systems models with the topologically well characterized partitions of limit behavior that make Conley's theory so valuable in those classical settings.
