Replication package for article 'Parallel Program Analysis via Range Splitting'
Creators: name: Anonymous Author(S)
Publisher: name: Zenodo
Year: 2022

description: Abstract. Ranged symbolic execution was proposed to scale symbolic
 execution by splitting the task of path exploration onto several workers.
 The split is conducted along path ranges which – simply speaking –
 describe sets of paths. Workers can then explore path ranges in parallel.
 In this paper, we propose ranged analysis as the generalization of ranged
 symbolic execution to arbitrary program analyses. This allows us to not
 only parallelize a single analysis, but also run different analyses on dif-
 ferent ranges of a program. Besides this generalization, we also provide a
 novel range splitting strategy along loop bounds, complementing the ex-
 isting random strategy of the original proposal. We implemented ranged
 analysis within the tool CPAchecker and evaluated it on programs
 from the SV-COMP benchmark. The evaluation in particular shows the
 superiority of loop bounds splitting over random splitting and that com-
 positions of ranged analyses can solve analysis tasks which none of the
 constituent analysis alone can solve. The artifact contains a file REAME.HTML, that contains all the information needed.
The case of muddled units in temporal discounting

Subjects: subject: cognitive modelling

description: While parameters are crucial components of cognitive models, relatively little importance has been given to their units. We show that this has lead to some parameters to be contaminated, posing problems for their interpretation. This has lead to the the illegal comparison of parameters with different units of measurement – this may invalidate parameter comparisons across participants, conditions, groups, or studies. We demonstrate that this problem affects two related models: Stevens’ Power Law and Rachlin’s delay discounting model. We show that it may even affect models which superficially avoid the incompatible units problem, such as hyperbolic discounting. We present simulation results to demonstrate the extent of the issues caused by the muddled units problem. We offer solutions in order to avoid the problem in the future or to aid in re-interpreting existing datasets.

description: Polycyclic Aromatic Hydrocarbon (PAH) molecules have been long proposed to be a major carrier of 'Unidentified Infrared' (UIR) emission bands that have been observed ubiquitously in various astrophysical environments. These molecules can potentially be an efficient reservoir of deuterium. Once the infrared properties of the deuterium- containing PAHs are well understood both experimentally and theoretically, the interstellar UIR bands can be used as a valuable tool to infer the cause of the deuterium depletion in the ISM. Density Functional Theory (DFT) calculations have been carried out on deuterium-containing ovalene variants to study the infrared properties of these molecules. These include deuterated ovalene, cationic deuterated ovalene, deuteronated ovalene and deuterated-deuteronated ovalene. We present a D/H ratio calculated from our theoretical study to compare with the observationally proposed D/H ratio.

description: Die Notwendigkeit einer Untersuchung über Beziehungshaltigkeit und Vernetzungen im Mathematikunterricht ergibt sich einerseits aus den aktuellen bildungspolitischen Forderungen, andererseits aus den reichhaltigen bildungsphilosophischen Traditionen im deutschsprachigem Raum(KMK 2012, 11). Das Ziel der vorliegenden Arbeit besteht vor allem in der Reflexion von Beziehungshaltigkeit und Vernetzungen im Mathematikunterricht. Diese Reflexion ist durch drei Fragen bestimmt: Was kann man als Lehrer über Beziehungshaltigkeit wissen? Wie kann man als Lehrer handeln, so dass die Schüler Beziehungen zwischen mathematischen Inhalten erkennen bzw. selbständig herstellen? Um handeln zu können, muss man die Wirklichkeit oder die Praxis (bzw. Empirie) kennen, in der man handelt. In diesem Sinne ist die vorliegende Arbeit aufgebaut. Dabei wird ein Versuch unternommen, die klassische Aufteilung zwischen Theorie und Empirie bzw. Praxis des Mathematikunterrichts aufzubrechen, um eine Verzahnung zwischen diesen zu verstärken. Das Herzstück der Arbeit bilden zwei ausgearbeitete und in der schulischen Arbeit erprobte Aufgabennetze (Pythagorasbaum und Rund ums Sechseck), die den Rahmen zur Reflexion bieten.
description: The need for a study on relations sustainability and networks in mathematics stems, on the one hand, from current education policy requirements, and, on the other, from the rich philosophical traditions of education in the German-speaking countries (KMK 2012, 11). The goal of the present work consists, above all, in reflecting on relations sustainability and networks in mathematics lessons. This reflection is guided by three questions: What can one know, as a teacher, about relations sustainability? How can one act a teacher to ensure that students recognise relationships between mathematical content, or independently produce such relations? In order to act, one must know the reality or practice (e.g. empiricism) in which one acts. The project is focused on the development and testing of worked examples of concrete task networks ("Pythagoras’ tree" and "Around the hexagon").

Experimental data includes total cross-sections up to 13 TeV, as well as differential distributions, for both single top and pair production. We also include the top quark width, charge asymmetries, and polarisation information from top decay products. We present bounds on the coefficients of dimension six operators, and examine the interplay between inclusive and differential measurements, and Tevatron / LHC data. All results are currently in good agreement with the Standard Model.

Investigation of phosphorylation and ligand binding of the focal adhesion targeting domain of focal adhesion kinase
Creators: name: Cable, Jennifer L.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Focal adhesion kinase (FAK) is a nonreceptor tyrosine kinase that localizes to focal adhesions upon integrin activation. FAK plays a key role in cell migration, cell cycle progression, and apoptosis. Because of its role in these processes, it is not surprising that FAK is also involved in tumor progression and metastasis. Overexpression of FAK often correlates with increased metastasis. The C-terminal focal adhesion targeting (FAT) domain of FAK is required for proper localization and subsequent activation of FAK. Phosphorylation of the FAT domain at Y926 by Src kinase is believed to delocalize FAK from focal adhesions and promote cell migration, angiogenesis, and tumor metastasis. Because of its role in such important processes, phosphorylation at Y926 is likely to be tightly regulated. Because the inherent conformation of Y926 is not favorable for Src recognition, phosphorylation of Y926 is thought to be regulated by changes in the conformation or dynamics of the region surrounding Y926. However, what regulates these conformational changes is unknown. In this study, we provide evidence that Src-mediated phosphorylation of Y926 is sensitive to pH in vitro and reveal a second site of Src-mediated phosphorylation in the FAT domain: Y1008. NMR studies of the FAT domain reveal pH-dependent changes in backbone dynamics in regions shown to be important for phosphorylation. In addition to understanding how phosphorylation is regulated, we also were interested in investigating how phosphorylation itself affects the characteristics of the FAT domain. To address this issue, we characterized several Y926 mutants of the FAT domain and determined that perturbation of Y926 affects paxillin binding. Therefore, it is likely that phosphorylation is incompatible with paxillin binding, which supports the hypothesis that phosphorylation delocalizes FAK from focal adhesions. Finally, we have investigated a possible interaction between the FAT domain and the protein talin. This interaction has been proposed as a secondary mechanism by which the FAT domain localizes FAK to focal adhesions. However, we were unable to detect an interaction under our conditions.

description: A detailed analysis of the lowest two moments of the $ϕ$ meson spectral function in vacuum and nuclear matter is performed. The consistency is examined between the constraints derived from finite energy QCD sum rules and the spectra computed within an improved vector dominance model, incorporating the coupling of kanonic degrees of freedom with the bare $ϕ$ meson. In the vacuum, recent accurate measurements of the $e^+ e^- \to K^+ K^-$ cross section allow us to determine the spectral function with high precision. In nuclear matter, the modification of the spectral function can be described by the interactions of the kaons from $ϕ\rightarrow K\bar{K}$ with the surrounding nuclear medium. This leads primarily to a strong broadening and an asymmetric deformation of the $ϕ$ meson peak structure. We confirm that, both in vacuum and nuclear matter, the zeroth and first moments of the corresponding spectral functions satisfy the requirements of the finite energy sum rules to a remarkable degree of accuracy. Limits on the strangeness sigma term of the nucleon are examined in this context. Applying our results to the second moment of the spectrum, we furthermore discuss constraints on four-quark condensates and the validity of the commonly used ground state saturation approximation.

Exploring the possible moderators between persuasion and smoking-related outcomes
Creators: name: Li, Shuang
Publisher: name: Open Science Framework
Year: 2022

description: This study aims to develop and explain the findings we got from two former studies in this research line, of which Study 1 suggested that self-persuasion works better for interdependent people for increasing their risk perception and negative attitudes towards smoking; while direct persuasion works better for independent people. Study 2 which used another paradigm to induce ones’ self-persuasion and direct persuasion did not replicate the results from Study 1, while the main effect of persuasion on smoking risk perception was found. Given the inconsistent results of Study 1 and Study 2, the influence of self-construal (i.e., independence and interdependence) on persuasion needs to be clarified in future studies. Therefore Study 3 will be conducted. This study is twofold. First it combines the 4 conditions in Study 1 and Study 2, aiming to figure out whether the different results come from two different paradigms used in these two studies, that is, different task types. Furthermore, measurements of self-efficacy, psychological reactance, cognitive effort, task involvement and persuasiveness will be tested to possibly explain the underlying processes of why the tasks lead to different results. Second, for exploratory reason, we add Power Distance Scale in this study to check whether it works as a moderator between persuasion and smoking-related outcomes.

description: We present post-Newtonian $N$-body simulations on mergers of accreting stellar-mass black holes (BHs), where such general relativistic effects as the pericenter shift and gravitational wave (GW) emission are taken into consideration. The attention is concentrated on the effects of the dynamical friction and the Hoyle-Lyttleton mass accretion by ambient gas. We consider a system composed of ten BHs with initial mass of $30~M_\odot$. As a result, we show that mergers of accreting stellar-mass BHs are classified into four types: a gas drag-driven, an interplay-driven, a three body-driven, or an accretion-driven merger. We find that BH mergers proceed before significant mass accretion, even if the accretion rate is $\sim10$ Eddington accretion rate, and then all BHs can merge into one heavy BH. Using the simulation results for a wide range of parameters, we derive a critical accretion rate ($\dot{m}_{\rm c}$), below which the BH growth is promoted faster by mergers. Also, it is found that the effect of the recoil by the GW emission can reduce $\dot{m}_{\rm c}$ especially in gas number density higher than $10^8~{\rm cm}^{-3}$, and enhance the escape probability of merged BHs. Very recently, a gravitational wave event, GW150914, as a result of the merger of a $\sim 30~M_\odot$ BH binary has been detected (Abbott et al. 2016). Based on the present simulations, the BH merger in GW150914 is likely to be driven by three-body encounters accompanied by a few $M_\odot$ of gas accretion, in high-density environments like dense interstellar clouds or galactic nuclei.

description: We discuss various results on Hilbert schemes of lines and conics and automorphism groups of smooth Fano threefolds with Picard rank 1. Besides a general review of facts well known to experts, the paper contains some new results, for instance, we give a description of the Hilbert scheme of conics on any smooth Fano threefold of index 1 and genus 10. We also show that the action of the automorphism group of a Fano threefold $X$ of index 2 (respectively, 1) on an irreducible component of its Hilbert scheme of lines (respectively, conics) is faithful if the anticanonical class of $X$ is very ample with a possible exception of several explicit cases. We use these faithfulness results to prove finiteness of the automorphism groups of most Fano threefolds and classify explicitly all Fano threefolds with infinite automorphism group. We also discuss a derived category point of view on the Hilbert schemes of lines and conics, and use this approach to identify some of them.

Portraying predestined partners?: German-Japanese mutal press depictions, 1919-1933
Creators: name: Law, Ricky W.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Traditionally scholars tried to explain the formation of the Berlin-Tokyo Axis using structural factors derived from the totalitarian, Marxist and latecomer theories. While these frameworks pinpoint the similarities between Japan and Germany, they do not shed light on the timing of the alliance and downplayed potential obstacles such as Nazi racism against non-Aryans, Japanese nationalistic anti-Western rhetoric, and the two countries' conflicting economic interests. In view of the shortcomings of the previous approaches, this essay examines interwar Japanese and German newspapers to gauge how the two countries portrayed each other. Evidence strongly indicates that while Germany and Japan exhibited interests in the other's culture, society and economy, they did not depict each other as a predestined ally but merely saw it as one nation among many and even frequently attacked its policies. These findings suggest that contingent, not structural, causes led to Japanese-German rapprochement.
La escritura de la infancia: entre la nación y el discurso político
Creators: name: Caña Jiménez, María del Carmen
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Este estudio es el primero que propone de manera formal aproximaciones teóricas para el análisis de la escritura de la infancia como sistema de narración. Con el propósito de establecer unas fuertes bases formales de investigación para la escritura de la infancia, se explora el procedimiento narrativo que conforma la infancia narrada como espacio articulatorio que sirve como vehículo de discursos ideológicos y políticos de la nación. A partir del análisis de obras contemporáneas españolas y colombianas, identifico tres posibles aproximaciones discursivas inherentes a la escritura de la infancia: la que muestra el espacio dialógico conformado a partir de la confluencia discursiva de la fantasía y la realidad; la que incorpora las voces históricas sancionadas y no sancionadas y, finalmente, la que presenta la escritura de la infancia como espacio de intercambios dinámicos de naturaleza terapéutica donde se conectan un pasado que se resiste a desaparecer y un presente invadido por los recuerdos traumáticos del pasado. Aunque la primera etapa de este estudio tiene un componente eminentemente formal, sus consecuencias hermenéuticas sirven como base de las interpretaciones de matiz más ideológico o político desarrolladas en los estadios subsiguientes. Estas aproximaciones discursivas permiten mostrar una función narrativa a partir de la escritura de la infancia como nodo de tensión alegórica a posibles interpretaciones de la nación, del mismo modo que una función narrativa que vincula la escritura de la infancia a la epistemología de los discursos políticos en torno a la memoria.
Ergodic Theory of p-adic Transformations

description: For a fixed prime p, we examine the ergodic properties and orbit equivalence classes of transformations on the p-adic numbers. Approximations and constructions are given that aid in the understanding of the ergodic properties of the transformations. Transformation types are calculated to give examples of transformations on measure spaces in various orbit equivalence classes. Moreover, we study the behavior of orbit equivalence classes under iteration. Finally, we give some preliminary investigations into the Haar measure and Hausdorff dimension of p-adic Julia sets and possible representations of the Chacon map as a 3-adic transformation.

Visual Mediations of Mourning and Melancholia in France, 1790 - 1830

History

description: This dissertation investigates the ways artists and patrons in early-nineteenth-century France used portraits, gardens, prints, and material objects to mitigate and publicly express experiences of loss, deep sorrow, and remembrance. By interpreting art objects alongside a range of textual materials, including popular novels, medical treatises, memoires, and art theory, I uncover the ways images of mourning and melancholia were linked to the cult of the individual while also expressing Romantic sensibilities about the psyche, imagination, and death itself. I trace evolving perceptions about melancholia, mourning, and death from the decades immediately following the French Revolution until the exile and death of Napoleon Bonaparte through case studies of specific objects. I argue that melancholia, death, and mourning rituals reflect the centrality of the post-revolutionary self and constitute a critical aspect of the social and visual climate of nineteenth-century France. Scholarship on the Romantic Period typically has focused on England and Germany where landscape painting expressed national identity and the artist's subjective experience. I distinguish a particular strain of French Romanticism that expresses loss and melancholia through the relationship between figures and spaces, arguing that Romanticism, an arts movement that emphasized emotion over reason and captured subjective sentimental experiences, is particularly suited to conveying personal responses to the period's events in France. Scholarship on mourning and melancholia in the eighteenth and nineteenth centuries in France has centered on the increased secularization of ideas associated with death and mourning. My research shows the limitations of this approach by demonstrating the complex, varied, and nuanced ways mourning objects were linked not only to religious practices but also to political and social events, Romanticism, and concepts of selfhood.
Methods for the Sequential Parallel Comparison Design
Creators: name: Silverman, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Sequential parallel comparison design (SPCD) has been proposed to increase the likelihood of success of clinical trials, especially trials with a possibly high placebo effect. SPCD is conducted with two stages, and subjects are randomized into three groups: (1) placebo in both periods, (2) placebo in the first period and active therapy in the second period, and (3) active therapy in both periods. Efficacy analysis of the study data includes all data from stage 1 and all placebo non-responding subjects from stage 2. Each stage is analyzed separately then the data are pooled to yield a single p-value.
      We first describe methods to use in a trial where we combine SPCD with the group sequential approach. We examine how to increase the sample size and adjust the design parameters during an interim analysis to increase power; these design parameters include allocation proportion to placebo in stage 1 of SPCD and weight of stage 1 data in the overall efficacy test statistic.
      Next, we develop new methods for SPCD with binary and time-to-event outcomes. These methods allow us to analyze SPCD stage-wise using the model of interest with adjustment for covariates. We show that under certain conditions the covariance between the estimated treatment effects in the two periods of SPCD is 0 under both null and alternative hypotheses. We also show that the stage-wise test statistics are uncorrelated under the null hypothesis. As a result, we can omit covariance in the construction of the overall test statistic and the confidence interval for the weighted sum of treatment effects.
      We develop framework and implementation of SPCD using permutation tests and bootstrap hypothesis testing. This approach allows the flexibility to use SPCD with any outcome. We examine two variations of permutation tests and three variations of the bootstrap. We show that the overall permutation as well as the stage-wise permutation test preserve type I error.  Additionally, the bootstrap that maintains the original stage 1 group sample sizes and the stage-wise bootstrap also preserve type I error. The stage-wise permutation test and bootstrap make it easy to evaluate SPCD data with popular software.

Orthogonal Transform Domain Based Neural Network Layers
Creators: name: Pan, Hongyi
Publisher: name: University of Illinois at Chicago
Year: 2023

description: In this thesis, we present a family of orthogonal-transform-based neural network (OTNN) layers to improve the performance of neural networks. We explore the concept of using orthogonal transforms in DNN layers to create OTNN layers that can better capture the important features of the input data. The thesis describes the design and implementation of OTNN layers using various orthogonal transforms such as Discrete Cosine Transform (DCT), Hadamard Transform (HT), and Discrete Wavelet Transform (DWT). Convolutional filtering operations are performed in the transform domain using element-wise multiplications, taking advantage of well-known convolution theorems. Trainable soft-thresholding layers that remove noise in the transform domain bring nonlinearity to the transform domain layers. The proposed layers reduce the number of parameters and multiplications significantly while improving the accuracy results of regular ResNets on the ImageNet-1K classification task. For example, compared to the vanilla ResNet-50 model, the DCT-based revised ResNet-50 reaches 0.82\% higher center-crop top-1 accuracy on the ImageNet-1K dataset with 11.5\% fewer parameters and 11.5\% fewer MACs. Furthermore, the proposed layers can be inserted with a batch normalization layer before the global average pooling layer in the conventional ResNets as an additional layer to improve classification accuracy with a negligible increase in the number of parameters and computational cost. For instance, without changing the convolutional base, an extra DCT-based layer improves the center-crop top-1 accuracy of ResNet-18 0.74\% on the ImageNet-1K dataset with only 2.3\% extra parameters and 0.3\% extra MACs. Moreover, we propose a hybrid quantum-classical HT layer for quantum computers. Since computing the $2\times2$ quantum HT is $O(1)$ in quantum computers and the quantum gates can be computed in parallel, the computational complexity of the hybrid quantum-classical HT on a $N$-length vector is $O(N)$. On the other hand, the complexity of the classical fast HT is $O(N\log N)$. Therefore, the HT-based layer gains benefit from quantum computers in terms of computational efficiency. In practice, we extended the OTNN layers into other tasks such as ECG-derived respiration rate estimation and ember fire detection, and the OTNN layers improved the performance of the classical models in these tasks. In the end, we present a Fourier-analysis-based pruning method for MobileNet-V2 and present its application to video-based wildfire detection. Overall, the thesis provides a comprehensive exploration of the concept of using orthogonal transforms in DNN layers to create OTNN layers that can improve accuracy and reduce the computational cost of DNNs. The proposed OTNN layers have potential applications in various fields, including image classification, detection, and data reconstruction.
Activation of G protein Signaling by a Non-Receptor Exchange Factor
Creators: name: Lee, Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: G proteins are biological signaling switches, which typically exist in a multi-protein complex at the cell periphery. Included in these systems is a seven-transmembrane spanning G protein coupled receptor (GPCR), a guanine nucleotide binding protein G alpha subunit and the obligate dimer G beta-gamma. GPCRs bind extracellular ligands, and transmit signals to intracellular G proteins. Ligand binding causes the G? subunit to exchange GDP for GTP. GTP-bound G alpha no longer interacts with G beta-gamma, and both entities are free to interact with downstream effector proteins. G alpha regulates the duration of the signal because G alpha is a GTPase, an activity that can be accelerated by GTPase Accelerating Proteins (GAPs) such as RGS proteins. The standard G protein signaling model, in its basic tenets, has remained largely unchanged for decades. This paradigm, however, fails to take into account recent findings that G proteins are not restricted to the cell periphery. A number of reports suggest that G alpha subunits in particular exist at, and even signal at, intracellular locations. These findings open up the possibility that G alpha_subunits regulate novel signaling pathways, away from the cell periphery, and potentially independent of the traditional "G alpha-beta-gamma-GPCR" paradigm. One particular example comes from the yeast model system, where the G protein Gpa1 regulates a cell fusion process called mating. It was recently identified that Gpa1 regulates a G beta-gamma-mediated signal at the cell periphery, and PI3K-mediated signal from the cell interior. Studies presented in this thesis focus on: 1) the regulation of Gpa1 signaling by post-translational modifications such as palmitoylation and ubiquitination, and 2) the activation of Gpa1 by non-receptor activators. Specifically, we detail the discovery that Arr4 functions as an exchange factor for Gpa1, and may contribute to the activation of Gpa1 at the endosome. Also, we find that Gpa1 localization to the plasma membrane and endosome is regulated by multiple forms of ubiquitination and also by dynamic palmitoylation. Finally, we create a novel method to be used for the identification of proteins involved in palmitoylation. Collectively, these discoveries further the growing understanding that G proteins function at intracellular locations.

We also extend related theorems on Frobenius eigenvalues and traces to Artin stacks.

description: We searched for an optical counterpart to the first gravitational wave source discovered by LIGO (GW150914), using a combination of the Pan-STARRS1 wide-field telescope and the PESSTO spectroscopic follow-up programme. As the final LIGO sky maps changed during analysis, the total probability of the source being spatially coincident with our fields was finally only 4.2 per cent. Therefore we discuss our results primarily as a demonstration of the survey capability of Pan-STARRS and spectroscopic capability of PESSTO. We mapped out 442 square degrees of the northern sky region of the initial map. We discovered 56 astrophysical transients over a period of 41 days from the discovery of the source. Of these, 19 were spectroscopically classified and a further 13 have host galaxy redshifts. All transients appear to be fairly normal supernovae and AGN variability and none is obviously linked with GW150914. We illustrate the sensitivity of our survey by defining parameterised lightcurves with timescales of 4, 20 and 40 days and use the sensitivity of the Pan-STARRS1 images to set limits on the luminosities of possible sources. The Pan-STARRS1 images reach limiting magnitudes of i = 19.2, 20.0 and 20.8 respectively for the three timescales. For long timescale parameterised lightcurves (with FWHM=~40d) we set upper limits of M_i <= -17.2 -0.9/+1.4 if the distance to GW150914 is D = 400 +/- 200Mpc. The number of type Ia SN we find in the survey is similar to that expected from the cosmic SN rate, indicating a reasonably complete efficiency in recovering supernova like transients out to D = 400 +/- 200 Mpc.

Management of Comorbid Depression in Veterans with Diabetes
Creators: name: Joseph, Letha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Objective: Patients with diabetes have an increased risk of developing depression. Comorbid depression in patients with diabetes affects their health-related quality of life, diabetes self-management, and health care utilization. The purpose of this study was to examine the feasibility of screening for depression in patients with diabetes while they were hospitalized for medical illness. Methods: The electronic health records of 193 patients admitted to medical units at a local facility from July 2016 to December 2016 were assessed for the presence of diabetes. Twenty-one patients with type 2 diabetes and with glycated hemoglobin above 7% were consented and screened for depression using the Patient Health Questionnaire (PHQ-2). Seven patients with positive symptoms for depression were enrolled in the study. The researcher alerted the medical provider via the electronic medical record about the patients with depression symptoms and the provider discussed options for management of depression with the patient and initiated treatment. The patients answered the PHQ-9, the Veterans RAND-12 and the Stanford Diabetes Questionnaire at baseline and at eight weeks and 12 weeks after discharge from the hospital. Five patients completed the study. At the completion of the study, the hospitalist team providers and the patients answered survey questions about the process. Results: The process of screening for depression at admission, notifying the provider by way of electronic medical record that the patient screened positive for depression with suggestions for medication and psychiatric counseling was feasible and acceptable to providers. Patients also felt the program was acceptable and helped them get the assistance they needed for depression. Statistics are not reported due to the small sample size. Conclusion: The results suggest that screening for depressive symptoms while admitted with medical illness was feasible and acceptable to patients and providers. A randomized controlled pilot study will be conducted next to establish efficacy.

description: The reduced expressions for a given element $w$ of a Coxeter group $(W, S)$ can be regarded as the vertices of a directed graph $\mathcal{R}(w)$; its arcs correspond to the braid moves. Specifically, an arc goes from a reduced expression $a$ to a reduced expression $b$ when $b$ is obtained from $a$ by replacing a contiguous subword of the form $stst...$ (for some distinct $s, t$ in $S$) by $tsts...$ (where both subwords have length $m_{s, t}$, the order of $st$ in $W$). We prove a strong bipartiteness-type result for this graph $\mathcal{R}(w)$: Not only does every cycle of $\mathcal{R}(w)$ have even length; actually, the arcs of $\mathcal{R}(w)$ can be colored (with colors corresponding to the type of braid moves used), and to every color $c$ corresponds an "opposite" color $c^{\operatorname{op}}$ (corresponding to the reverses of the braid moves with color $c$), and for any color $c$, the number of arcs in any given cycle of $\mathcal{R}(w)$ having color in $\left\{c, c^{\operatorname{op}}\right\}$ is even. This is a generalization and strengthening of a 2014 result by Bergeron, Ceballos and Labbé. We state further conjectural extensions.

description: Hurwitz numbers count ramified genus $g$, degree $d$ coverings of the projective line with with fixed branch locus and fixed ramification data. Double Hurwitz numbers count such covers, where we fix two special profiles over $0$ and $\infty$ and only simple ramification else. These objects feature insteresting structural behaviour and connections to geometry. In this paper, we introduce the notion of pruned double Hurwitz numbers, generalizing the notion of pruned simple Hurwitz numbers in \cite{DN13}. We show that pruned double Hurwitz numbers, similar to usual double Hurwitz numbers, satisfy a cut-and-join recursion and are piecewise polynomial with respect to the entries of the two special ramification profiles. Furthermore double Hurwitz numbers can be computed from pruned double Hurwitz numbers. To sum up, it can be said that pruned double Hurwitz numbers count a relevant subset of covers, leading to considerably smaller numbers and computations, but still featuring the important properties we can observe for double Hurwitz numbers.

description: We analyze charged-current electron-neutrino cross sections on Carbon. We consider two different theoretical approaches, on one hand the Continuum Random Phase Approximation (CRPA) which allows a description of giant resonances and quasielastic excitations, on the other hand the RPA-based calculations which are able to describe multinucleon emission and coherent and incoherent pion production as well as quasielastic excitations. We compare the two approaches in the genuine quasielastic channel, and find a satisfactory agreement between them at large energies while at low energies the collective giant resonances show up only in the CRPA approach. We also compare electron-neutrino cross sections with the corresponding muon-neutrino ones in order to investigate the impact of the different charged-lepton masses. Finally, restricting to the RPA-based approach we compare the sum of quasielastic, multinucleon emission, coherent and incoherent one-pion production cross sections (folded with the electron-neutrino T2K flux) with the charged-current inclusive electron-neutrino differential cross sections on Carbon measured by T2K. We find a good agreement with the data. The multinucleon component is needed in order to reproduce the T2K electron-neutrino inclusive cross sections.

description: In animals, gas exchange between blood and tissues occurs in narrow vessels, whose diameter is comparable to that of a red blood cell. Red blood cells must deform to squeeze through these narrow vessels, transiently blocking or occluding the vessels they pass through. Although the dynamics of vessel occlusion have been studied extensively, it remains an open question why microvessels need to be so narrow. We study occlusive dynamics within a model microvascular network: the embryonic zebrafish trunk. We show that pressure feedbacks created when red blood cells enter the finest vessels of the trunk act together to uniformly partition red blood cells through the microvasculature. Using mathematical models as well as direct observation, we show that these occlusive feedbacks are tuned throughout the trunk network to prevent the vessels closest to the heart from short-circuiting the network. Thus occlusion is linked with another open question of microvascular function: how are red blood cells delivered at the same rate to each micro-vessel? Our analysis shows that tuning of occlusive feedbacks increase the total dissipation within the network by a factor of 11, showing that uniformity of flows rather than minimization of transport costs may be prioritized by the microvascular network.
