Throughout Joseph Weizenbaum's life, he liked to tell this story about a computer program he’d created back in the 1960s as a professor at MIT. It was a simple chatbot named ELIZA that could interact with users in a typed conversation. As he enlisted people to try it out, Weizenbaum saw similar reactions again and again -- people were entranced by the program. They would reveal very intimate details about their lives. It was as if they’d just been waiting for someone (or something) to ask. ELIZA was one of the first computer programs that could convincingly simulate human conversation, which Weizenbaum found frankly a bit disturbing.

Cofiring wood and coal at Fairbanks, Alaska, area electrical generation facilities represents an opportunity to use woody biomass from clearings within the borough's wildland-urban interface and from other sources, such as sawmill residues and woody material intended for landfills. Potential benefits of cofiring include air quality improvements, reduced greenhouse gas emissions, market and employment development opportunities, and reduction of municipal wood residues at area landfills. Important issues that must be addressed to enable cofiring include wood chip uniformity and quality, fuel mixing procedures, transportation and wood chip processing costs, infrastructure requirements, and long-term biomass supply. Additional steps in implementing successful cofiring programs could include test burns, an assessment of area biomass supply and treatment needs, and a detailed economic and technical feasibility study. Although Fairbanks North Star Borough is well positioned to use biomass for cofiring at coal burning facilities, long-term cofiring operations would require expansion of biomass sources beyond defensible-space-related clearings alone. Long-term sources could potentially include a range of woody materials including forest harvesting residues, sawmill residues, and municipal wastes.

A study of commercial timber harvesting activities in Oregon and Washington was conducted from 2011 through 2015 to characterize current tree utilization, logging operations, and assist with estimating the amount of woody biomass left onsite after harvesting.

A 4-year-old Douglas-fir plantation in the western Washington Cascades was monitored for 8 years after fertilization with potassium (K), nitrogen (N), and K+N to determine fertilizer effects on rates of mortality from laminated root rot (LRR) and other causes relative to a nonfertilized control.

We examine the use of woody residues, primarily from forest harvesting or wood products manufacturing operations (and to a limited degree from urban wood wastes), as a feedstock for direct-combustion bioenergy systems for electrical or thermal power applications. We examine opportunities for utilizing biomass for energy at several different scales, with an emphasis on larger scale electrical power generation at stand-alone facilities, and on smaller scale facilities (thermal heating only) such as governmental, educational, or other institutional facilities. We then identify west-wide barriers that tend to inhibit bioenergy applications, including accessibility, terrain, harvesting costs, and capital costs. Finally, we evaluate the role of government as a catalyst in stimulating new technologies and new uses of biomass material.

This book is intended to help people better understand how wood energy is helping to revitalize rural Alaskan communities by reducing energy costs, creating jobs, and helping to educate the next generation.

ELIZABETH "BETTY" A. ZOBAC
Cedar Rapids


Betty A. Zobac, passed away unexpectedly on Tuesday, May 5, 2020, at the Dennis & Donna Oldorf Hospice House of Mercy. She was 92.
Betty was born in Cedar Rapids, Iowa, on Oct. 29,
1927. She was the beloved
and only child to Francis
and Mary (Cahill) Sullivan. Betty attended grade school
at Immaculate Conception Catholic School in Cedar Rapids. Then carried on her education at St. Patrick's High School where she graduated in 1946.
It wasn't long after when Betty married the love of her life; Frank Zobac, in August 1947, at the Immaculate Catholic Church in Cedar Rapids. To this union four children were born. Betty and Frank were married for 69 years. Frank passed away on Dec. 15, 2016.
Betty was very proud of her ancestry and Irish heritage. Betty and Frank actually got engaged on St. Patrick's Day 1947. She loved celebrating her culture every year on St. Patrick's Day by cooking corned beef and cabbage for her entire family.
Betty and Frank were a well-liked and social couple. They developed many friendships throughout their years and were always ready to have fun. The two loved to go out on the town dancing. They would often take a weekend trip to Chicago at the Allerton Hotel on Michigan Avenue. While there they would enjoy Broadway style shows, concerts or even a Cubs game. Later in life Betty and Frank would have season tickets to Iowa Hawkeyes football games. They rarely missed a bowl game during the Hayden Fry era. Neither did they miss a Friday night card group, any bingo game in town or an evening of Frank singing karaoke to Betty.
After having four young children, Betty worked the night shift in the pediatric department of Mercy Hospital for three years. Her endless energy and work ethic were remarkable. Betty also was a true fashionista and carried that passion over into her next career. From Killian's to Armstrong's then Coach House Fashions; she worked in retail women's clothing for over 15 years. While still maintaining her voguish taste, Betty's greatest accomplishment of her career began in 1961. As the backbone of the family business; Betty successfully ran the company as general manager of Frank Zobac Construction Co. Frank Zobac Construction Co. was in business for over 60 years.
Betty was the matriarch of her family. Betty loved to cook for and with her family. Like her taste for fashion, she was ahead of her time when it came to preparing meals for her family. Betty's culinary creativity led to many delicious and sometimes interesting meals. Rarely following a recipe; she inspired many. Her children, grandchildren and great-grandchildren have carried on her passion for cooking to this day. What Betty started in her little kitchen back in 1947 will be passed down throughout her family for generations. Betty also had an extraordinary love for dachshunds. Whether on the couch or in Hy-Vee, it was rare to see Betty not carrying one of her many spoiled dachshunds.
Betty's memory will continue to live on through her four children, Susan (Dennis) Draker of Marion, Mark (Connie) Zobac of Vinton, Kathy (Doug) Klinger of Marion and Debra Zobac of Marion; eight grandchildren, Amy (Clint) Houdek, Jeff (Diana) Draker, Barrett (Kiley) Scorpil, James (Christina) Zobac, Christopher Goodrow, Staci (John) Willems, Traci (Jeff) Chisholm and Michelle Ramirez; and her 16 great-grandchildren.
A memorial service will be held at a date to be determined. In lieu of flowers, donations may be made to Dennis and Donna Oldorf Hospice House in memoriam of Frank and Betty Zobac. Please mail to: Susan Draker 2845 Hunters Ridge Rd. Marion, IA 52302.
Please leave a message or tribute to Betty's family on our web page, www.cedarmemorial.com, under Obituaries.

For the second consecutive day the number of Iowa patients hospitalized with COVID-19 has dropped.

The Iowa Department of Public Health reported Saturday that 402 people were hospitalized with the coronavirus, down five from the previous day, and down 15 from its current peak of 417 on Thursday.

Saturday’s totals mark the first time back-to-back COVID-19 hospitalization decreases since figures had begun being tracked.

Nine deaths in Iowa were recorded Saturday, according to the Department of Public Health, bringing the total to 252. But it snapped a streak of four consecutive days in which 10 or more deaths were recorded in Iowa.

Four of the deaths were in Polk County, bringing Polk’s total to 58 — matching Linn County’s as most in the state.

Saturday was the first time since Monday that no deaths in Linn County were reported.

Two deaths were in Jasper County, one each in Johnson, Muscatine and Tama counties.

Four of those who died were 81 years of age and older, three were 61 to 80 and two were aged 41 to 60.

Saturday’s report also showed there now have been a total of 29 outbreaks recorded in long-term care facilities statewide.

Including Saturday’s latest figures from the Department of Public Health — with 214 positive cases, for a total of 11,671 — these are the top 10 Iowa counties in terms of total cases:

• Polk — 2,194

• Woodbury — 1,554

• Black Hawk — 1,477

• Linn — 819

• Marshall — 702

• Dallas — 660

• Johnson — 549

• Muscatine — 471

• Tama — 327

• Louisa — 282.

More than 71,000 Iowans — one of 43 — have been tested, and 16.3 percent of those tested have been positive cases, according to the state.

Forty-six percent of Iowa deaths have been those age 81 and older, while 87 percent are 61 and older. Fifty-one percent have been male.

Beginning this past Friday, Gov. Kim Reynolds permitted more businesses to partially reopen.

“I’m proud to say that Iowans do what they always do and they responded,” she said at her Thursday news conference, her most recent. “So since we’ve kind of really accomplished what we were trying to do, ... now we have shifted our focus from mitigation and resources to managing and containing virus activity as we begin to open Iowa back up.”

Reynolds met with President Donald Trump on Wednesday at the White House to discuss the pandemic and mitigation strategies in the state.

Vice President Mike Pence visited Iowa Friday, when he met with faith leaders and agricultural and food company executives.

We prove a continuity result for the shearlet transform when restricted to the space of smooth and rapidly decreasing functions with all vanishing moments. We define the dual shearlet transform, called here the shearlet synthesis operator, and we prove its continuity on the space of smooth and rapidly decreasing functions over $mathbb{R}^2 imesmathbb{R} imesmathbb{R}^ imes$. Then, we use these continuity results to extend the shearlet transform to the space of Lizorkin distributions, and we prove its consistency with the classical definition for test functions.

In a multitype branching process, it is assumed that immigrants arrive according to a nonhomogeneous Poisson or a generalized Polya process (both processes are formulated as a nonhomogeneous birth process with an appropriate choice of transition intensities). We show that the renormalized numbers of objects of the various types alive at time $t$ for supercritical, critical, and subcritical cases jointly converge in distribution under those two different arrival processes. Furthermore, some transient moment analysis when there are only two types of particles is provided. AMS 2000 subject classifications: Primary 60J80, 60J85; secondary 60K10, 60K25, 90B15.

We introduce primal and dual stochastic gradient oracle methods for decentralized convex optimization problems. Both for primal and dual oracles the proposed methods are optimal in terms of the number of communication steps. However, for all classes of the objective, the optimality in terms of the number of oracle calls per node in the class of methods with optimal number of communication steps takes place only up to a logarithmic factor and the notion of smoothness. By using mini-batching technique we show that all proposed methods with stochastic oracle can be additionally parallelized at each node.

The article is devoted to the expansion of iterated Stratonovich stochastic integrals of arbitrary multiplicity $k$ $(kinmathbb{N})$ based on the generalized iterated Fourier series. The case of Fourier-Legendre series as well as the case of trigonotemric Fourier series are considered in details. The obtained expansion provides a possibility to represent the iterated Stratonovich stochastic integral in the form of iterated series of products of standard Gaussian random variables. Convergence in the mean of degree $2n$ $(nin mathbb{N})$ of the expansion is proved. Some modifications of the mentioned expansion were derived for the case $k=2$. One of them is based of multiple trigonomentric Fourier series converging almost everywhere in the square $[t, T]^2$. The results of the article can be applied to the numerical solution of Ito stochastic differential equations.

We develop a distributional framework for the shearlet transform $mathcal{S}_{psi}colonmathcal{S}_0(mathbb{R}^2) omathcal{S}(mathbb{S})$ and the shearlet synthesis operator $mathcal{S}^t_{psi}colonmathcal{S}(mathbb{S}) omathcal{S}_0(mathbb{R}^2)$, where $mathcal{S}_0(mathbb{R}^2)$ is the Lizorkin test function space and $mathcal{S}(mathbb{S})$ is the space of highly localized test functions on the standard shearlet group $mathbb{S}$. These spaces and their duals $mathcal{S}_0^prime (mathbb R^2),, mathcal{S}^prime (mathbb{S})$ are called Lizorkin type spaces of test functions and distributions. We analyze the continuity properties of these transforms when the admissible vector $psi$ belongs to $mathcal{S}_0(mathbb{R}^2)$. Then, we define the shearlet transform and the shearlet synthesis operator of Lizorkin type distributions as transpose mappings of the shearlet synthesis operator and the shearlet transform, respectively. They yield continuous mappings from $mathcal{S}_0^prime (mathbb R^2)$ to $mathcal{S}^prime (mathbb{S})$ and from $mathcal{S}^prime (mathbb S)$ to $mathcal{S}_0^prime (mathbb{R}^2)$. Furthermore, we show the consistency of our definition with the shearlet transform defined by direct evaluation of a distribution on the shearlets. The same can be done for the shearlet synthesis operator. Finally, we give a reconstruction formula for Lizorkin type distributions, from which follows that the action of such generalized functions can be written as an absolutely convergent integral over the standard shearlet group.

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.

In information theory, the so-called log-sum inequality is fundamental and a kind of generalization of the non-nagativity for the relative entropy. In this paper, we show the generalized log-sum inequality for two functions defined for scalars. We also give a new result for commutative matrices. In addition, we demonstrate further results for general non-commutative positive semi-definite matrices.

The aim of this paper is to obtain a generalized CK-extension theorem in superspace for the bi-axial Dirac operator. In the classical commuting case, this result can be written as a power series of Bessel type of certain differential operators acting on a single initial function. In the superspace setting, novel structures appear in the cases of negative even superdimensions. In these cases, the CK-extension depends on two initial functions on which two power series of differential operators act. These series are not only of Bessel type but they give rise to an additional structure in terms of Appell polynomials. This pattern also is present in the structure of the Pizzetti formula, which describes integration over the supersphere in terms of differential operators. We make this relation explicit by studying the decomposition of the generalized CK-extension into plane waves integrated over the supersphere. Moreover, these results are applied to obtain a decomposition of the Cauchy kernel in superspace into monogenic plane waves, which shall be useful for inverting the super Radon transform.

We introduce natural deformation classes of generalized K"ahler structures using the Courant symmetry group. We show that these yield natural extensions of the notions of K"ahler class and K"ahler cone to generalized K"ahler geometry. Lastly we show that the generalized K"ahler-Ricci flow preserves this generalized K"ahler cone, and the underlying real Poisson tensor.

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.

Deep learning-based models, such as convolutional neural networks, have advanced various segments of computer vision. However, this technology is rarely applied to seismic shot gather noise localization problem. This letter presents an investigation on the effectiveness of a multi-scale feature-fusion-based network for seismic shot-gather noise localization. Herein, we describe the following: (1) the construction of a real-world dataset of seismic noise localization based on 6,500 seismograms; (2) a multi-scale feature-fusion-based detector that uses the MobileNet combined with the Feature Pyramid Net as the backbone; and (3) the Single Shot multi-box detector for box classification/regression. Additionally, we propose the use of the Focal Loss function that improves the detector's prediction accuracy. The proposed detector achieves an AP@0.5 of 78.67\% in our empirical evaluation.

In this paper, we present three distributed algorithms to solve a class of generalized Nash equilibrium (GNE) seeking problems in strongly monotone games. The first one (SD-GENO) is based on synchronous updates of the agents, while the second and the third (AD-GEED and AD-GENO) represent asynchronous solutions that are robust to communication delays. AD-GENO can be seen as a refinement of AD-GEED, since it only requires node auxiliary variables, enhancing the scalability of the algorithm. Our main contribution is to prove converge to a variational GNE of the game via an operator-theoretic approach. Finally, we apply the algorithms to network Cournot games and show how different activation sequences and delays affect convergence. We also compare the proposed algorithms to the only other in the literature (ADAGNES), and observe that AD-GENO outperforms the alternative.

Sparse models require less memory for storage and enable a faster inference by reducing the necessary number of FLOPs. This is relevant both for time-critical and on-device computations using neural networks. The stabilized lottery ticket hypothesis states that networks can be pruned after none or few training iterations, using a mask computed based on the unpruned converged model. On the transformer architecture and the WMT 2014 English-to-German and English-to-French tasks, we show that stabilized lottery ticket pruning performs similar to magnitude pruning for sparsity levels of up to 85%, and propose a new combination of pruning techniques that outperforms all other techniques for even higher levels of sparsity. Furthermore, we confirm that the parameter's initial sign and not its specific value is the primary factor for successful training, and show that magnitude pruning cannot be used to find winning lottery tickets.

Visual localization is a useful alternative to standard localization techniques. It works by utilizing cameras. In a typical scenario, features are extracted from captured images and compared with geo-referenced databases. Location information is then inferred from the matching results. Conventional schemes mainly use low-level visual features. These approaches offer good accuracy but suffer from scalability issues. In order to assist localization in large urban areas, this work explores a different path by utilizing high-level semantic information. It is found that object information in a street view can facilitate localization. A novel descriptor scheme called "semantic signature" is proposed to summarize this information. A semantic signature consists of type and angle information of visible objects at a spatial location. Several metrics and protocols are proposed for signature comparison and retrieval. They illustrate different trade-offs between accuracy and complexity. Extensive simulation results confirm the potential of the proposed scheme in large-scale applications. This paper is an extended version of a conference paper in CBMI'18. A more efficient retrieval protocol is presented with additional experiment results.

This paper proposes a fully automated atlas-based pancreas segmentation method from CT volumes utilizing atlas localization by regression forest and atlas generation using blood vessel information. Previous probabilistic atlas-based pancreas segmentation methods cannot deal with spatial variations that are commonly found in the pancreas well. Also, shape variations are not represented by an averaged atlas. We propose a fully automated pancreas segmentation method that deals with two types of variations mentioned above. The position and size of the pancreas is estimated using a regression forest technique. After localization, a patient-specific probabilistic atlas is generated based on a new image similarity that reflects the blood vessel position and direction information around the pancreas. We segment it using the EM algorithm with the atlas as prior followed by the graph-cut. In evaluation results using 147 CT volumes, the Jaccard index and the Dice overlap of the proposed method were 62.1% and 75.1%, respectively. Although we automated all of the segmentation processes, segmentation results were superior to the other state-of-the-art methods in the Dice overlap.

In this paper, some useful necessary and sufficient conditions for the unique solution of the generalized absolute value equation (GAVE) $Ax-B|x|=b$ with $A, Bin mathbb{R}^{n imes n}$ from the optimization field are first presented, which cover the fundamental theorem for the unique solution of the linear system $Ax=b$ with $Ain mathbb{R}^{n imes n}$. Not only that, some new sufficient conditions for the unique solution of the GAVE are obtained, which are weaker than the previous published works.

In recent years, all-neural end-to-end approaches have obtained state-of-the-art results on several challenging automatic speech recognition (ASR) tasks. However, most existing works focus on building ASR models where train and test data are drawn from the same domain. This results in poor generalization characteristics on mismatched-domains: e.g., end-to-end models trained on short segments perform poorly when evaluated on longer utterances. In this work, we analyze the generalization properties of streaming and non-streaming recurrent neural network transducer (RNN-T) based end-to-end models in order to identify model components that negatively affect generalization performance. We propose two solutions: combining multiple regularization techniques during training, and using dynamic overlapping inference. On a long-form YouTube test set, when the non-streaming RNN-T model is trained with shorter segments of data, the proposed combination improves word error rate (WER) from 22.3% to 14.8%; when the streaming RNN-T model trained on short Search queries, the proposed techniques improve WER on the YouTube set from 67.0% to 25.3%. Finally, when trained on Librispeech, we find that dynamic overlapping inference improves WER on YouTube from 99.8% to 33.0%.
