description: September 4, 2020 Student Election Group Episode 2 Friday's 4:30-5:30 General As our mission statement says, “The Salem Center for Policy is dedicated to helping students and business leaders better understand the costs, benefits and consequences of policy decisions.” The weeks before a presidential election are when many Americans think most about policy, and discussions of the upcoming election often throw off more heat than light, so our mission requires us to try to help make sense of the choice facing America. Towards that end, we’ve put together a group of students and faculty to articulate and evaluate the beliefs and values behind our votes. Our discussion will take place every Friday at 4:30 PM CT leading up to the election. Join the seminar via Zoom. Thank you to all of our students who participated in the second discussion. Please continue to follow this page, our YouTube Channel, and our other social media accounts to view the next sessions. It takes work for human beings to know reality and to form and achieve values within it. Understanding this work enables us to take greater control of our minds and our lives. Human beings—many of us, at least—aspire to be objective in our thinking and our decision-making. We aspire to conform our thinking to the facts, rather than allowing our opinions to be determined accidental features of our psychologies and environments. We aspire to achieve things that are genuinely valuable, rather than things that merely seem appealing to some person or group. In our professional lives we aspire to profit by providing our customers (or clients or employers) with goods or services that are genuinely valuable to them. In our civic lives, we seek to preserve or create the sort of government that protects and makes possible all of the activities described above. The Objectivity Program seeks to help us realize these aspirations by illuminating their philosophical foundations, and the ways in which different perspectives on these fundamental issues lead to different approaches to life, business, and governmental policy.

description: Time variable delays due to radio wave propagation in the ionized interstellar medium are a substantial source of error in pulsar timing array efforts. We describe the physical origin of these effects, discussing dispersive and scattering effects separately. Where possible, we give estimates of the magnitude of timing errors produced by these effects and their scaling with radio frequency. Although there is general understanding of the interstellar medium propagation errors to be expected with pulsar timing array observations, detailed comparison between theory and practice is still in its infancy, particularly with regard to scattering effects.

description: MAUP (modifiable areal unit problem) is a fundamental problem for spatial data management and analysis. As an instantiation of MAUP in online transportation platforms, region generation (i.e., specifying the areal unit for service operations) is the first and vital step for supporting spatiotemporal transportation services such as ride-sharing and freight transport. Most existing region generation methods are manually specified (e.g., fixed-size grids), suffering from poor spatial semantic meaning and inflexibility to meet service operation requirements. In this paper, we propose RegionGen, a data-driven region generation framework that can specify regions with key characteristics (e.g., good spatial semantic meaning and predictability) by modeling region generation as a multi-objective optimization problem. First, to obtain good spatial semantic meaning, RegionGen segments the whole city into atomic spatial elements based on road networks and obstacles (e.g., rivers). Then, it clusters the atomic spatial elements into regions by maximizing various operation characteristics, which is formulated as a multi-objective optimization problem. For this optimization problem, we propose a multi-objective co-optimization algorithm. Extensive experiments verify that RegionGen can generate more suitable regions than traditional methods for spatiotemporal service management.

description: An efficient green synthesis of diethyl((substituted phenyl)((4-(N-(5-methyl-4,5-dihydroisoxazol-3-yl)sulfamoyl)phenyl) amino)methyl)phosphonates was accomplished by the condensation of 4-amino-N-(5-methyl-4,5-dihydroisoxazol-3yl) benzenesulfonamide with various aldehydes and diethyl phosphite using mesoporous titania-ceria mixed oxide (MTCMO) as a nanocatalyst under microwave irradiation and solvent-free conditions. Antimicrobial activity was performed for the synthesized compounds and the compounds 4a, 4c, 4d, 4e and 4f exhibited highest inhibitory activity against Escherichia coli using Penicillin and Tetracycline as standards. In addition, molecular docking studies were also carried out against Cox-2 with Celocoxib as the standard.

description: The functional renormalization group (fRG) approach has the property that, in general, the flow equation for the two-particle vertex generates $\mathcal{O}(N^4)$ independent variables, where $N$ is the number of interacting states (e.g. sites of a real-space discretization). In order to include the flow equation for the two-particle vertex one needs to make further approximations if $N$ becomes too large. We present such an approximation scheme, called the coupled-ladder approximation, for the special case of onsite interaction. Like the generic third-order-truncated fRG, the coupled-ladder approximation is exact to second order and is closely related to a simultaneous treatment of the random phase approximation in all channels, i.e. summing up parquet-type diagrams. The scheme is applied to a one-dimensional model describing a quantum point contact.

BLOC: A Game-Theoretic Approach to Orchestrate CPS with Check Blocks against Cyber Attacks

description: Cyber-Physical Systems (CPS) will be core to most emerging computing systems. A myriad of activities in our lives will rely on the correct operation of these systems, from transportation and energy domains, to manufacturing and healthcare. Securing CPS against cyber-attacks, however, is challenging due to the wide range of possible attacks — from stealthy ones that seek to manipulate control and measurement signals to malware that infects host machines that control the physical process. This has prompted the research community to develop targeted methods that protect and check the run-time operation of the CPS. Since protecting signals and checking for errors result in performance penalties, they must be performed within the delay bounds dictated by the control loop. Due to the large number of potential checks that can be performed, coupled with various degrees of their effectiveness to detect a wide range of attacks, strategic assignment of these checks in the control loop is a critical endeavor. In this talk, I will present a coherent runtime framework — which we coin BLOC — for orchestrating the CPS with check blocks to secure them against cyber-attacks. BLOC capitalizes on game theoretical techniques to enable the defender to find an optimal randomized use of check blocks to secure the CPS while abiding to the control-loop delay constraints. In the first part of the talk, I will present a Stackelberg game model for stateless blocks and a Markov game model for stateful ones and derive optimal policies that minimize the worst-case damage from rational adversaries. In the second part of the talk, I will present a Deep Reinforcement Learning framework that solves for optimal/sub-optimal assignments of check blocks against the explosion in the size of the state/action spaces. I will present results obtained from extensive simulations as well as real instantiations of CPS. By first understanding the behavioral consequences of policy changes in cyberspace, we are better able to defend and understand the increasingly connected world in which we live. One of the greatest drivers of human progress in the last couple of decades is the ability to access technology and the internet, but how we enforce cybersecurity is a pressing problem.

description: Extending previous work on generalised geometry, we explicitly construct an E7-valued vielbein in eleven dimensions that encompasses the scalar bosonic degrees of freedom of D=11 supergravity, by identifying new "generalised vielbeine" in eleven dimensions associated with the dual 6-form potential and the dual graviton. By maintaining full on-shell equivalence with the original theory at every step, our construction altogether avoids the constraints usually encountered in other approaches to generalised geometry and, as a side product, also furnishes the non-linear ansatz for the dual (magnetic) 7-form flux for any non-trivial compactification of D=11 supergravity, complementing the known non-linear ansaetze for the metric and the 4-form flux. A preliminary analysis of the generalised vielbein postulate for the new vielbein components reveals tantalising hints of new structures beyond D=11 supergravity and ordinary space-time covariance, and also points to the possible D=11 origins of the embedding tensor. We discuss the extension of these results to E8.

description: The strong structure-property coupling in rare-earth nickelates has spurred the realization of new quantum phases in rapid succession. Recently, topotactic transformations have provided a new platform for the controlled creation of oxygen vacancies and, therewith, for the exploitation of such coupling in nickelates. Here, we report the emergence of oxygen vacancy ordering in Pr$_{0.92}$Ca$_{0.08}$NiO$_{2.75}$ single crystals obtained via a topotactic reduction of the perovskite phase Pr$_{0.92}$Ca$_{0.08}$NiO$_{3}$, using CaH$_2$ as the reducing agent. We unveil a brownmillerite-like ordering pattern of the vacancies by high-resolution scanning transmission electron microscopy, with Ni ions in alternating square-pyramidal and octahedral coordination along the pseudocubic [100] direction. Furthermore, we find that the crystal structure acquires a high level of internal strain, where wavelike modulations of polyhedral tilts and rotations accommodate the large distortions around the vacancy sites. Our results suggest that atomic-resolution electron microscopy is a powerful method to locally resolve unconventional crystal structures that result from the topotactic transformation of complex oxide materials.

Detailed measurements are performed with point and extended geometry sources to obtain a complete response of the detector. An effective model of the detector has been made with GEANT4 based Monte Carlo simulations which agrees with experimental data within 5%. This setup will be used for qualification and selection of radio-pure materials to be used in a cryogenic bolometer for the study of Neutrinoless Double Beta Decay in $^{124}$Sn as well as for other rare event studies. Using this setup, radio-impurities in the rock sample from India-based Neutrino Observatory (INO) site have been estimated.

description: Measurements of a well-characterised standard sample can verify the performance of an instrument. Typically, small-angle neutron scattering instruments are used to investigate a wide range of samples and may often be used in a number of configurations. Appropriate standard samples are useful to test different aspects of the performance of hardware as well as that of the data reduction and analysis software. Measurements on a number of instruments with different intrinsic characteristics and designs in a round robin can not only better characterise the performance for a wider range of conditions but also, perhaps more importantly, reveal the limits of the current state of the art of small-angle scattering. The exercise, followed by detailed analysis, tests the limits of current understanding as well as uncovers often forgotten assumptions, simplifications and approximations that underpin the current practice of the technique. This paper describes measurements of polystyrene latex, radius 72 nm with a number of instruments. Scattering from monodisperse, uniform spherical particles is simple to calculate and displays sharp minima. Such data test the calibrations of intensity, wavelength and resolution as well as the detector response. Smoothing due to resolution, multiple scattering and polydispersity has been determined. Sources of uncertainty are often related to systematic deviations and calibrations rather than random counting errors. The study has prompted development of software to treat modest multiple scattering and to better model the instrument resolution. These measurements also allow checks of data reduction algorithms and have identified how they can be improved. The reproducibility and the reliability of instruments and the accuracy of parameters derived from the data are described.

We study observables based on measuring ratios of color-singlet currents via Higgs boson and Drell-Yan production, which may be accessed also at large pile-up, and used for an experimental program on QCD physics of gluon fusion processes in the LHC high-luminosity runs. We present results of Monte Carlo calculations for a few specific examples.

description: The statistical and dynamical properties of ions in the selectivity filter of the KcsA ion channel are considered on the basis of molecular dynamics (MD) simulations of the KcsA protein embedded in a lipid membrane surrounded by an ionic solution. A new approach to the derivation of a Brownian dynamics (BD) model of ion permeation through the filter is discussed, based on unbiased MD simulations. It is shown that depending on additional assumptions, ion's dynamics can be described either by under-damped Langevin equation with constant damping and white noise or by Langevin equation with a fractional memory kernel. A comparison of the potential of the mean force derived from unbiased MD simulations with the potential produced by the umbrella sampling method demonstrates significant differences in these potentials. The origin of these differences is an open question that requires further clarifications.

description: Background: Seasonal influenza is a significant cause of mortality and morbidity worldwide. Despite annual recommendations, influenza vaccination uptake rates are disproportionately lower among nurses compared to other health care professionals, especially when compared to physicians. Nurses have an additional risk of exposure to influenza infection due to the nature of their work. Aim: To determine the effectiveness of interventions in increasing seasonal influenza vaccination uptake among nurses. Methods: Evidence on the effectiveness of interventions to improve seasonal influenza vaccination uptake among nurses was systematically reviewed. A comprehensive search of six electronic databases and grey literature was undertaken. A minimum of two reviewers completed study selection, data extraction and risk of bias assessment independently. Results: One hundred and thirty-four studies were identified of which one cluster randomised trial met the inclusion criteria. The results of the included study found the implementation of an intervention with multiple components increased nurses’ seasonal influenza vaccination rates during a single influenza season in geriatric healthcare settings in France. As the evidence in this review was very limited, it was not possible to make recommendations regarding which interventions were effective at increasing the seasonal influenza vaccination rate for nurses. Conclusion: This systematic review highlights a lack of high-quality studies that assessed interventions to improve the seasonal influenza vaccination of nurses. In view of the likelihood of influenza and the coronavirus (COVID-19) pandemic occurring together, it is imperative to have evidence on effective interventions for the nursing workforce and for policy decision makers.

Few specimens exist to substantiate the specific taxonomy and distribution of the genus. Revised by Hershkovitz (1962), who acknowledged several nominal species but indicated their probable synonymy under E. chinchilloides, as Mann (1978) so formalized for Chilean populations. Yanez et al. (1987) summarized extant specimen data for Euneomys and concluded that one species is represented. Others have recognized two or more (e.g., Osgood, 1943; Pearson and Christie, 1991; Pine et al., 1979). The latter arrangement is more nearly correct but must be sustained within the context of rigorous revisions. Holotype of Reithrodon fossor Thomas, 1899, type species of Chelemyscus Thomas, 1925, is a composite, the designated type skull referrable to Euneomys (Osgood, 1943: 164; Pearson, 1984:231).

description: The sparse Mixture-of-Experts (Sparse-MoE) framework efficiently scales up model capacity in various domains, such as natural language processing and vision. Sparse-MoEs select a subset of the "experts" (thus, only a portion of the overall network) for each input sample using a sparse, trainable gate. Existing sparse gates are prone to convergence and performance issues when training with first-order optimization methods. In this paper, we introduce two improvements to current MoE approaches. First, we propose a new sparse gate: COMET, which relies on a novel tree-based mechanism. COMET is differentiable, can exploit sparsity to speed up computation, and outperforms state-of-the-art gates. Second, due to the challenging combinatorial nature of sparse expert selection, first-order methods are typically prone to low-quality solutions. To deal with this challenge, we propose a novel, permutation-based local search method that can complement first-order methods in training any sparse gate, e.g., Hash routing, Top-k, DSelect-k, and COMET. We show that local search can help networks escape bad initializations or solutions. We performed large-scale experiments on various domains, including recommender systems, vision, and natural language processing. On standard vision and recommender systems benchmarks, COMET+ (COMET with local search) achieves up to 13% improvement in ROC AUC over popular gates, e.g., Hash routing and Top-k, and up to 9% over prior differentiable gates e.g., DSelect-k. When Top-k and Hash gates are combined with local search, we see up to $100\times$ reduction in the budget needed for hyperparameter tuning. Moreover, for language modeling, our approach improves over the state-of-the-art MoEBERT model for distilling BERT on 5/7 GLUE benchmarks as well as SQuAD dataset.

description: We design, characterize, and couple Boolean phase oscillators that include state-dependent feedback delay. The state-dependent delay allows us to realize an adjustable coupling strength, even though only Boolean signals are exchanged. Specifically, increasing the coupling strength via the range of state-dependent delay leads to larger locking ranges in uni- and bi-directional coupling of oscillators in both experiment and numerical simulation with a piecewise switching model. In the unidirectional coupling scheme, we unveil asymmetric triangular-shaped locking regions (Arnold tongues) that appear at multiples of the natural frequency of the oscillators. This extends observations of a single locking region reported in previous studies. In the bidirectional coupling scheme, we map out a symmetric locking region in the parameter space of frequency detuning and coupling strength. Because of large scalability of our setup, our observations constitute a first step towards realizing large-scale networks of coupled oscillators to address fundamental questions on the dynamical properties of networks in a new experimental setting.

DMP du projet "Rôles de la régulation hydrique et thermique dans les réponses écologiques au changement climatique"
Creators: name: Le Galliard, Jean-François
Publisher: name: Zenodo

description: Le changement climatique modifie les conditions thermiques et la disponibilité de l'eau dans le temps et
 l'espace. La sensibilité et la résilience des animaux ectothermes face à ce changement sont déterminés par
 leurs capacités et tolérances physiologiques et comportementales. Les réponses individuelles aux
 changements des conditions thermiques et de la disponibilité de l'eau in situ dépendent spécifiquement de la
 thermorégulation (c'est-à-dire la régulation physiologique et comportementale de la température corporelle)
 et de l'hydrorégulation (c'est-à-dire la régulation physiologique et comportementale du budget hydrique).
 Comment les interactions entre la thermorégulation et l'hydrorégulation influencent la vulnérabilité au
 changement climatique demeure cependant pratiquement inconnu. Ici, nous utiliserons l'écophysiologie et
 l'écologie comportementale pour améliorer notre compréhension de ce problème critique chez les
 ectothermes terrestres. En se concentrant sur les reptiles squamates (lézards et serpents), nous combinerons
 des modèles biophysiques mécanistes, des études empiriques de traits physiologiques et comportementaux
 aux niveaux individuel et populationnel chez deux espèces modèles dans deux massifs montagneux en
 France, des simulations de niches climatiques et des analyses comparatives. Nous serons ainsi en mesure
 de décrire et de comprendre pour la première fois les patrons de covariation entre la thermorégulation et
 l'hydrorégulation afin d'améliorer notre capacité à prédire les effets écologiques de deux facteurs du
 changement climatique

description: Статья посвящена изучению шерстяных лент, обнаруженных на усадьбе «Б» Пятницкого раскопа в Старой Руссе. Было исследовано 19 лент из слоёв конца 1240-х — 1420-х гг. Проведен морфологический и технологический анализ. Установлено, что для изготовления лент использовали нити низкого качества. Все исследованные находки можно разделить на две группы: тканые на бёрдо и тканые на дощечках, при этом первые более распространены. В слоях второй половины XIII в. обнаружен фрагмент третьей кромки ткани, изготовленной на вертикальном ткацком станке. Два фрагмента лент выполнены в технике двухличной саржи. Изучены три ленты со следами закрепления нити в готовом изделии (пояса). Из них наибольший интерес представляет образец, в котором конец изделия заплетён в узел, а выходящие из него нити свиты в бахрому.

COMMENTS: Hershkovitz (1962) had suggested that other nominal species would prove to be synonyms of E. chinchilloides. This taxonomy has been followed (Mann, 1978; Yanez et al., 1987) but misrepresents species diversity in the genus (see Pearson and Christie, 1991).

Introduction to Khovanov Homologies. III. A new and simple tensor-algebra construction of Khovanov-Rozansky invariants

description: We continue to develop the tensor-algebra approach to knot polynomials with the goal to present the story in elementary and comprehensible form. The previously reviewed description of Khovanov cohomologies for the gauge group of rank N-1=1 was based on the cut-and-join calculus of the planar cycles, which are involved rather artificially. We substitute them by alternative and natural set of cycles, not obligatory planar. Then the whole construction is straightforwardly lifted from SL(2) to SL(N) and reproduces Khovanov-Rozansky (KR) polynomials, simultaneously for all values of N. No matrix factorization and related tedious calculations are needed in such approach, which can therefore become not only conceptually, but also practically useful.

On The {\it Fermi} -Lat Surplus of the Diffuse Galactic Gamma-Ray Emission

description: Recent observations of the diffuse Galactic \gr emission (DGE) by the {\it Fermi} Large Area Telescope ({\it Fermi}-LAT) have shown significant deviations, above a few GeV until about 100 GeV, from DGE models that use the GALPROP code for the propagation of cosmic ray (CR) particles outside their sources in the Galaxy and their interaction with the target distributions of the interstellar gas and radiation fields. The surplus of radiation observed is most pronounced in the inner Galaxy, where the concentration of CR sources is strongest. The present study investigates this "{\it Fermi}-LAT Galactic Plane Surplus" by estimating the \gr emission from the sources themselves, which is disregarded in the above DGE models. It is shown that indeed the expected hard spectrum of CRs, still confined in their sources (SCRs), can explain this surplus. The method is based on earlier studies regarding the so-called EGRET GeV excess which by now is generally interpreted as an instrumental effect. The contribution from SCRs is predicted to increasingly exceed the DGE models also above 100 GeV, up to \gr energies of about ten TeV, where the corresponding surplus exceeds the hadronic part of the DGE by about one order of magnitude. Above such energies the emission surplus should decrease again with energy due to the finite life-time of the assumed supernova remnant sources. Observations of the DGE in the inner Galaxy at 15 TeV with the Milagro \gr detector and, at TeV energies, with the ARGO-YBJ detector are interpreted to provide confirmation of a significant SCR contribution to the DGE.

description: The passive management approach offers conservative investors a way to reduce risk concerning the market. This investment strategy aims at replicating a specific index, such as the NASDAQ Composite or the FTSE100 index. The problem is that buying all the index's assets incurs high rebalancing costs, and this harms future returns. The index tracking problem concerns building a portfolio that follows a specific benchmark with fewer transaction costs. Since a subset of assets is required to solve the index problem this class of problems is NP-hard, and in the past years, researchers have been studying solution approaches to obtain tracking portfolios more practically. This work brings an analysis, spanning the last decade, of the advances in mathematical approaches for index tracking. The systematic literature review covered important issues, such as the most relevant research areas, solution methods, and model structures. Special attention was given to the exploration and analysis of metaheuristics applied to the index tracking problem.

On the finite amplitudes for open graphs in Abelian dynamical colored Boulatov-Ooguri models

description: In the work [Int. J. Theor. Phys. 50, 2819 (2011)], it has been proved that the radiative corrections of the 2-point function in the SU(2) Boulatov tensor model generates a relevant (in the Renormalization Group sense) contribution of the form of a Laplacian. Such a term which was missing in the initial Boulatov model action should be added in that action before discussing the renormalization analysis of this model. In this work, by linearizing the group manifold, we prove that the amplitudes associated with Feynman graphs with external legs of the colored Boulatov model over U(1)^3 endowed with a Laplacian dynamics are all convergent. We conjecture that the same feature happens for the corresponding Boulatov model over SU(2). Higher rank models are also discussed.

description: We derive a family of risk-sensitive reinforcement learning methods for agents, who face sequential decision-making tasks in uncertain environments. By applying a utility function to the temporal difference (TD) error, nonlinear transformations are effectively applied not only to the received rewards but also to the true transition probabilities of the underlying Markov decision process. When appropriate utility functions are chosen, the agents' behaviors express key features of human behavior as predicted by prospect theory (Kahneman and Tversky, 1979), for example different risk-preferences for gains and losses as well as the shape of subjective probability curves. We derive a risk-sensitive Q-learning algorithm, which is necessary for modeling human behavior when transition probabilities are unknown, and prove its convergence. As a proof of principle for the applicability of the new framework we apply it to quantify human behavior in a sequential investment task. We find, that the risk-sensitive variant provides a significantly better fit to the behavioral data and that it leads to an interpretation of the subject's responses which is indeed consistent with prospect theory. The analysis of simultaneously measured fMRI signals show a significant correlation of the risk-sensitive TD error with BOLD signal change in the ventral striatum. In addition we find a significant correlation of the risk-sensitive Q-values with neural activity in the striatum, cingulate cortex and insula, which is not present if standard Q-values are used.

description: We show that tri-layer structures combining epsilon-negative and magneto-optical material layers can exhibit unidirectional resonant photon tunneling phenomena that can discriminate between circularly-polarized (CP) waves of given handedness impinging from opposite directions, or between CP waves with different handedness impinging from the same direction. This physical principle, which can also be interpreted in terms of a Fabry-Perot-type resonance, may be utilized to design compact optical isolators for CP waves. Within this framework, we derive simple analytical conditions and design formulae, and quantitatively assess the isolation performance, also taking into account the unavoidable imperfections and nonidealities.
