description: The rich multifractal properties of fluid turbulence illustrated by the work of Parisi and Frisch are related explicitly to Leray's weak solutions of the three-dimensional Navier-Stokes equations. Directly from this correspondence it is found that the set on which energy dissipates, $\mathbb{F}_{m}$, has a range of dimensions $\Dim=3/m$ ($1 \leq m \leq \infty$), and a corresponding range of sub-Kolmogorov dissipation inverse length scales $Lη_{m}^{-1} \leq Re^{3/(1+\Dim)}$ spanning $Re^{3/4}$ to $Re^{3}$. Correspondingly, the multifractal model scaling parameter $h$, must obey $h \geq h_{min}$ with $-\twothirds \leq h_{min} \leq \third$.

description: In this paper we present several examples of solving algorithmic problems from the Google Code Jam programming contest with Picat programming language using declarative techniques: constraint logic programming and tabled logic programming. In some cases the use of Picat simplifies the implementation compared to conventional imperative programming languages, while in others it allows to directly convert the problem statement into an efficiently solvable declarative problem specification without inventing an imperative algorithm.

description: This paper explores the effect of the LMC on the mass estimates obtained from the timing argument. We show that accounting for the presence of the LMC systematically lowers the Local Group mass ($M_{\rm LG}$) derived from the relative motion of the Milky Way--Andromeda pair. Motivated by this result we apply a Bayesian technique devised by Peñarrubia et al. (2014) to simultaneously fit (i) distances and velocities of galaxies within 3~Mpc and (ii) the relative motion between the Milky Way and Andromeda derived from HST observations, with the LMC mass ($M_{\rm LMC}$) as a free parameter. Our analysis returns a Local Group mass $M_{\rm LG}=2.64^{+0.42}_{-0.38}\times 10^{12}M_\odot$ at a 68\% confidence level. The masses of the Milky Way, $M_{\rm MW}=1.04_{-0.23}^{+0.26}\times 10^{12}M_\odot$, and Andromeda, $M_{\rm M31}=1.33_{-0.33}^{+0.39}\times 10^{12}M_\odot$, are consistent with previous estimates that neglect the impact of the LMC on the observed Hubble flow. We find a (total) LMC mass $M_{\rm LMC}=0.25_{-0.08}^{+0.09}\times 10^{12}M_\odot$, which is indicative of an extended dark matter halo and supports the scenario where this galaxy is just past its first pericentric approach. Consequently, these results suggest that the LMC may induce significant perturbations on the Galactic potential.

Do Automatic Comment Generation Techniques Fall Short? Exploring the Influence of Method Dependencies on Code Understanding
Creators: name: Annonymous
Publisher: name: Zenodo
Year: 2025

description: Method-level comments are essential for improving code comprehension and facilitating software maintenance. With advancements in large language models (LLMs), automated comment generation has become a key focus in software development research. However, current approaches often overlook method dependencies where one method relies on or calls other methods, which impacts comment quality and code understandability. This study investigates the prevalence and characteristics of dependent methods in software projects and introduces a dependency-aware approach for generating method-level comments. Using a dataset of 10 popular GitHub projects written in Java, we found that dependent methods, which comprise 69.25% of all methods, show higher engagement and frequency of change than independent ones. Using an analysis of over 448K dependent methods and 199K independent methods, we observed that state-of-the-art finetuned models, such as CodeT5+ and CodeBERT, face challenges in generating comprehensive method-level comments for dependent methods compared to independent ones. Similarly, LLM-based comment generation models, including ASAP and CodeLlama, demonstrated comparable performance trends when evaluated on a substantial sample. To address this, we propose HelpCOM, a novel dependency-aware comment generation model that incorporates helper method information to improve comment clarity, comprehensiveness, and relevance. Experimental results show that HelpCOM outperforms state-of-the-art models by 5.6% to 50.4% across syntactic (e.g., BLEU), semantic (e.g., SentenceBERT), and LLM-based evaluation metrics. Additionally, a survey of 156 software professionals confirms that HelpCOM significantly improves the comprehensibility of code involving dependent methods. These findings highlight its potential to enhance documentation practices, code maintainability, and developer productivity in large-scale systems.

description: A large number of food policy councils (FPCs) exist in the United States, Canada, and Tribal Nations (N = 278), yet there are no tools designed to measure their members' perceptions of organizational capacity, social capital, and council effectiveness. Without such tools, it is challenging to determine best practices for FPCs and to measure change within and across councils over time. This study describes the development, testing, and findings from the Food Policy Council Self-Assessment Tool (FPC-SAT). The assessment measures council practices and council members' perceptions of the following concepts: leadership, breadth of active membership, council climate, formality of council structure, knowledge sharing, relationships, member empowerment, community context, synergy, and impacts on the food system. All 278 FPCs listed on the Food Policy Network's Online Directory were recruited to complete the FPC-SAT. Internal reliability (Cronbach's α) and inter-rater reliability (AD, rWG(J), ICC [intraclass correlations][1], ICC[2]) were calculated, and exploratory and a confirmatory factor analyses were conducted. Responses from 354 FPC members from 94 councils were used to test the assessment. Cronbach's α ranged from 0.79 to 0.93 for the scales. FPC members reported the lowest mean scores on the breadth of active membership scale (2.49; standard deviation [SD], 0.62), indicating room for improvement, and highest on the leadership scale (3.45; SD, 0.45). The valid FPC-SAT can be used to identify FPC strengths and areas for improvement, measure differences across FPCs, and measure change in FPCs over time.

description: Eine Wurzelkanalbehandlung ist eine dringende Maßnahme bei einer irreversiblen Pulpitis. Der Kanal wird dabei aufbereitet, mit Spüllösungen gereinigt, desinfiziert und anschließend mit einem Sealer und einem Guttaperchastift abgedichtet, sodass keine Flüssigkeiten oder Bakterien mehr in den Kanal eindringen können. Zudem werden durch den Sealer kleine Unebenheiten in der Kanalwand ausgeglichen und Seitenkanäle verschlossen. Er dient außerdem als Verbindungselement zwischen Gutta- perchastift und dem Wurzeldentin. Der Sealer Apexit Plus der Firma Ivoclar Vivadent auf Calciumsalicylatbasis eignet sich laut Hersteller auch für Techniken mit erwärmtem Guttaperchastift (vgl. Quelle: Apexit Plus Gebrauchsinformation). Die Heißfülltechnik hat den Vorteil, dass das erwärmte Guttapercha besser Irregularitäten im Kanal benetzen und ausgleichen kann als bei der verbreiteteren Kaltfülltechnik. Falls sich die Materialeigenschaften von Apexit Plus bei bestimmten Temperaturen wider Erwarten negativ verändern sollten, hätte das möglicherweise eine Undichtigkeit der Füllung zur Folge und könnte eine erneute Pulpitis hervorrufen. Im Rahmen dieser Arbeit wurde daher das Verhalten des Calciumsalicylat- Sealers Apexit Plus bei verschieden hohen Temperaturen, wie sie bei der Warmfülltechnik auftreten, mit dem Ziel geprüft, die Auswirkungen auf den Haftverbund zu ermitteln. Aus diesen Ergebnissen zeigte sich, dass die Materialeigenschaften von Apexit Plus nicht negativ durch den Temperaturanstieg beeinflusst werden. Somit kann davon ausgegangen werden, dass der Sealer auch für Warmfülltechniken geeignet ist.

description: The stability of $ν=1/3$ Fractional Chern Insulator (FCI) phase is analysed on the example of checkerboard lattice undergoing a transition into Lieb lattice. The transition is performed by the addition of a second sublattice, whose coupling to the checkerboard sites is controlled by sublattice staggered potential. We investigate the influence of these sites on the many body energy gap between three lowest energy states and the fourth state. We consider cases with different complex phases acquired in hopping and a model with a flattened topologically nontrivial band. We find that an interaction with the additional sites either open the single-particle gap or enlarge the existing one, which translates into similar effect on the many-particle gap. Evidences of FCI phase for a region in a parameter space with larger energy gap are shown by looking at momenta of the three-fold degenerate ground state, spectral flow, and quasihole excitation spectrum.

description: Es gibt viele Diagnosen im Fachbereich der Gynäkologie, welche die Lebensqualität der Patientinnen stark beeinflussen können und die das Risiko erhöhen, eine Depression zu entwickeln. Das Ziel dieser Studie war es, zu untersuchen, welche gynäkologischen Diagnosen mit Depressionen assoziiert sind. Diese retrospektive Fall-Kontroll-Studie basiert auf Daten aus der Disease Analyzer Datenbank (IQVIA). In die Studie eingeschlossen wurden 5.893 Frauen im Alter von 18 Jahren oder älter mit Depressionen und 5.893 im Alter angeglichene Kontrollen ohne Depressionen, die im Jahr 2019 (Indexdatum) in einer von 256 gynäkologischen Praxen in Deutschland untersucht wurden. Es wurde ein multivariates logistisches Regressionsmodell angewandt, um die Assoziation zwischen den 33 vordefinierten Diagnosen, die innerhalb von fünf Jahren vor dem Indexdatum dokumentiert wurden, und Depressionen zu untersuchen. Insgesamt waren 9 Krankheiten signifikant mit der Diagnose einer Depression assoziiert. Die stärkste Assoziation wurde für Brustkrebs ermittelt (OR=2,11 (95% Konfidenzintervall (CI)=1,76-2,52)), gefolgt von Infertilität (OR=1,91 (95% CI=1,48- 2,47)), Krebs der weiblichen Genitalorgane exklusive der Brust (OR=1,87 (95% CI=1,32-2,66)), und sexuelle Dysfunktion (OR=1,63 (95% CI=1,27-2,09)). Weitere Krankheiten, die eine signifikante Assoziation mit Depressionen hatten, waren Endometriose, Mastodynie, Kandidose, Infektionen, die vorwiegend durch Geschlechtsverkehr übertragen werden, und Harninkontinenz. Außerdem wiesen Patientinnen, die an mehreren Krankheiten gleichzeitig litten, eine höhere Wahrscheinlichkeit dafür auf, mit Depressionen diagnostiziert zu werden (OR=1,40 für zwei Krankheiten bis zu OR=2,38 für >6 Krankheiten im Vergleich zu keinen Krankheiten). Eine große Bandbreite von Krankheiten, die in gynäkologischen Praxen diagnostiziert wurden, waren mit der Diagnose einer Depression assoziiert. Diese Zusammenhänge zu kennen und zu verstehen, kann Gynäkologen dabei helfen Depressionen bei ihren Patientinnen zu erkennen und sie direkt an Psychologen oder Psychiater zu verweisen und so dazu beizutragen, dass Depressionen in unserer Gesellschaft besser bewältigt werden.

description: Ovarian cancer (OC) is one of the deadliest gynecological malignancies due to its early and wide-spread peritoneal dissemination, with the omentum being the preferred site of metastasis. The underlying molecular mechanisms are not yet fully understood. Basal cell adhesion molecule (BCAM) is a laminin α5 (LAMA5) binding protein. BCAM is expressed in multiple forms in OC, including the full-length protein (BCAM1), a splicing variant lacking the cytoplasmic domain (BCAM2) and soluble BCAM (sBCAM). Although BCAM is associated with a poor survival of OC, its contribution to peritoneal metastasis remains elusive. In this study, we identified ADAM10 as a major BCAM sheddase produced by OC cells and determined the proteolytic cleavage sites. All BCAM forms interfered with the interaction of LAMA5 with integrin β1 to inhibit the adhesion and migration of tumor cells on a LAMA5-containing matrix, indicating the functionality of both membranebound and soluble BCAM. It is, however, unlikely that this effect of BCAM on adherent tumor cells significantly affects peritoneal dissemination of OC cells, as suggested by several lines of evidence: (i) the known essential function of collagen I (COL1) rather than laminins in the adhesion of OC cells to peritoneal organs; (ii) our observation that BCAM had no detectable effect on COL1-dependent OC cell adhesion; and (iii) the known pivotal role of tumor cell spheroids rather than single cells in metastatic dissemination. We discovered, however, that all forms of BCAM negatively regulate the compactness of LAMA5-rich tumor cell spheroids, thereby promoting their dispersion in a threedimensional collagen matrix, which in turn facilitates the clearance of mesothelial cells and promotes their trans-mesothelial invasion into the omentum. Importantly, we also observed a significant association between BCAM expression and a poor clinical outcome in OC, highlighting the potential translational relevance of these findings. In summary, our study provides new mechanistic insights into the role of BCAM in ovarian cancer progression and highlights its potential as a therapeutic target for peritoneal metastasis.

description: To quantify the prevalence of 10 quit methods commonly used by adult cigarette smokers, we used data from a nationally representative longitudinal (2014-2016) online survey of US adult cigarette smokers (n = 15,943). Overall, 74.7% of adult current cigarette smokers used multiple quit methods during their most recent quit attempt. Giving up cigarettes all at once (65.3%) and reducing the number of cigarettes smoked (62.0%) were the most prevalent methods. Substituting some cigarettes with e-cigarettes was used by a greater percentage of smokers than the nicotine patch, nicotine gum, or other cessation aids approved by the US Food and Drug Administration. Further research into the effectiveness of e-cigarettes as a cessation aid is warranted.

description: Neural Style Transfer (NST) refers to a class of algorithms able to manipulate an element, most often images, to adopt the appearance or style of another one. Each element is defined as a combination of Content and Style: the Content can be conceptually defined as the what and the Style as the how of said element. In this context, we propose a custom NST framework for transferring a set of styles to the motion of a robotic manipulator, e.g., the same robotic task can be carried out in an angry, happy, calm, or sad way. An autoencoder architecture extracts and defines the Content and the Style of the target robot motions. A Twin Delayed Deep Deterministic Policy Gradient (TD3) network generates the robot control policy using the loss defined by the autoencoder. The proposed Neural Policy Style Transfer TD3 (NPST3) alters the robot motion by introducing the trained style. Such an approach can be implemented either offline, for carrying out autonomous robot motions in dynamic environments, or online, for adapting at runtime the style of a teleoperated robot. The considered styles can be learned online from human demonstrations. We carried out an evaluation with human subjects enrolling 73 volunteers, asking them to recognize the style behind some representative robotic motions. Results show a good recognition rate, proving that it is possible to convey different styles to a robot using this approach.

description: We proceed to generalize the Yang-Baxter (YB) deformation of Wess-Zumino-Witten (WZW) model to the Lie supergroups case. This generalization enables us to utilize various kinds of solutions of the (modified) graded classical Yang-Baxter equation ((m)GCYBE) to classify the YB deformations of WZW models based on the Lie supergroups. We obtain the inequivalent solutions (classical r-matrices) of the (m)GCYBE for the $gl(1|1)$ and $({\cal C}^3 +{\cal A})$ Lie superalgebras in the non-standard basis, in such a way that the corresponding automorphism transformations are employed. Then, the YB deformations of the WZW models based on the $GL(1|1)$ and $(C^3 + A)$ Lie supergroups are specified by skew-supersymmetric classical r-matrices satisfying (m)GCYBE. In some cases for both families of deformed models, the metrics remain invariant under the deformation, while the components of $B$-fields are changed. After checking the conformal invariance of the models up to one-loop order, it is concluded that the $GL(1|1)$ and $(C^3 + A)$ WZW models are conformal theories within the classes of the YB deformations preserving the conformal invariance. However, our results are interesting in themselves, but at a constructive level, may prompt many new insights into (generalized) supergravity solutions.

Predicting PTSD as a result of perpetration

Publisher: name: No Publisher Supplied

description: A wealth of research has confirmed the psychological stress individuals experience as victims of violence (Ayalon, 1993; Figley 1985 & 1986), with far less exploration into the stress linked to perpetrating serious violence. Only in recent years have researchers considered the psychological stress of perpetrating serious violence and atrocities (Nichter et al., 2021; Maguen & Pietrzak, 2021; MacNair, 2002). In response to poor community reintegration and postwar adjustment among veterans, Congress enacted the 1983 Veterans’ Health Care Amendments, mandating two comprehensive investigations into the effects of war, the National Vietnam Veterans Readjustment Study (NVVRS, 1988) and the National Vietnam Veterans Longitudinal Study (NVVLS, 2012). The NVVRS estimated the prevalence of PTSD at 15% of males and 9% of females more than a decade after service and the NVVLS estimated the prevalence at 11% of males, 7% of females, and 20% of the sample struggling with chronic symptoms and depression, nearly 40 years after service (Corry et al., 2016).The proposed study utilizes data collected from 1,450 participants of both studies: 16% Black, 18% Hispanic, 66% White and 67% males. Thirty-eight percent of respondents endorsed experiences with direct killing, 37% endorsed responsibility for the death of women, children, or the elderly, and 40% endorsed responsibility for the death of a civilian. Utilizing hierarchical regression models, we hypothesize that perpetrating violence (i.e. killing) significantly predicts PTSD, controlling for various wartime experiences including PTSD at time 1 in the prediction for PTSD at time 2, nearly 40 years postwar.

description: Infectious diseases continue to pose a global threat, particularly in low-resource settings where timely diagnosis and treatment are often unavailable. The emergence of smart diagnostic systems powered by artificial intelligence (AI), machine learning, and advanced biosensors offers new solutions for the rapid detection, identification, and monitoring of infectious pathogens. These systems enhance diagnostic precision, reduce the burden on healthcare professionals, and enable real-time surveillance that can help contain outbreaks before they escalate. This paper delves into the technological foundation of smart diagnostic systems, explores their various applications in detecting infectious diseases, and discusses the implications of integrating AI into laboratory and point-of-care diagnostics. It also addresses the challenges of scalability, cost, data privacy, and integration with existing healthcare frameworks while highlighting the future directions of smart diagnostics in shaping global health security.

description: Wormholes (WH) require negative energy, and therefore an exotic matter source. Since Casimir energy is negative, it has been speculated as a good candidate to source that objects a long time ago. However only very recently a full solution for $D = 4$ has been found by Garattini, thus the Casimir energy can be a source of traversable WHs. In the manuscript published by the authors, we show that this solution is possible for all space-time of dimension $D > 3$. Recently, Garattini sought to analyze the effects of Yukawa-type terms on shape functions and obtained promising results. However, it assumes reasonably questionable premises when establishing a non-homogeneity in the Equation of State, when assuming a fixation between the constants that is only observed in the usual model and when considering the Zero Tidal Condition, not observed in Casimir's wormholes. In this work, we study the effects generated by Yukawa-type corrective factors on traversable wormhole solutions generated by Casimir energy without assuming such premises. We observe that, in addition to being possible to build traversable wormholes that satisfy all the necessary conditions, it is possible to obtain an adequate fixation of the constants in order to recover the standard case without a double limit. It was observed that, in the global and constant cases, it is possible to set a value in the shielding parameter that makes the wormhole generate a repulsive gravitational force. Finally, we observed that in the constant case there was a limitation for the shielding factor, something not observed in the original article.

description: BACKGROUND: Food access interventions are promising strategies for improving dietary intake, which is associated with better health. However, studies examining the relationship between food access and intake are limited to observational designs, indicating a need for more rigorous approaches. The Veggie Van (VV) program was a cluster-randomized intervention designed to address the gap between food access and intake. In this article, we aim to describe the approaches involved in recruiting community partners to participate in VV.

COMMUNITY CONTEXT: The VV mobile market aimed to improve access to fresh fruits and vegetables by providing subsidized, high-quality, local produce in low-resource communities in North Carolina. This study describes the strategies and considerations involved in recruiting community partners and individual participants for participation in the VV program and evaluation.

METHODS: To recruit partners, we used various strategies, including a site screener to identify potential partners, interest forms to gauge future VV use and prioritize enrollment of a high-need population, marketing materials to promote VV, site liaisons to coordinate community outreach, and a memorandum of understanding between all invested parties.

OUTCOME: A total of 53 community organizations and 725 participants were approached for recruitment. Ultimately, 12 sites and 201 participants were enrolled. Enrollment took 38 months, but our approaches helped successfully recruit a low-income, low-access population. The process took longer than anticipated, and funding constraints prevented certain strategies from being implemented.

INTERPRETATION: Recruiting community partners and members for participation in a multi-level, community-based intervention was challenging. Strategies and lessons learned can inform future studies.

description: Though Fourier Transforms (FTs) are a common technique for finding correlation functions, they are not typically used in computations of the anisotropy of the two-point correlation function (2PCF) about the line of sight in wide-angle surveys because the line-of-sight direction is not constant on the Cartesian grid. Here we show how FTs can be used to compute the multipole moments of the anisotropic 2PCF. We also show how FTs can be used to accelerate the 3PCF algorithm of Slepian & Eisenstein (2015). In both cases, these FT methods allow one to avoid the computational cost of pair counting, which scales as the square of the number density of objects in the survey. With the upcoming large datasets of DESI, Euclid, and LSST, FT techniques will therefore offer an important complement to simple pair or triplet counts.

description: Based on the here developed functional analytic machinery we extend the theory of operator sampling and identification to apply to operators with stochastic spreading functions. We prove that identification with a delta train signal is possible for a large class of stochastic operators that have the property that the autocorrelation of the spreading function is supported on a set of 4D volume less than one and this support set does not have a defective structure. In fact, unlike in the case of deterministic operator identification, the geometry of the support set has a significant impact on the identifiability of the considered operator class. Also, we prove that, analogous to the deterministic case, the restriction of the 4D volume of a support set to be less or equal to one is necessary for identifiability of a stochastic operator class.

description: Die Inzidenz von Hirnmetastasen nimmt stetig zu und stellt eine ernste Komplikation von soliden Karzinomen dar. Unbehandelt ist die Prognose mit etwa einem Monat nahezu infaust. In diesem meist palliativen Krankheitsstadium ist die Intensität der eventuell nebenwirkungsreichen Therapie zur Verlängerung des Überlebens gegenüber der Lebensqualität abzuwägen. Mit einer verlässlichen Schätzung der Überlebenszeit könnte die Entscheidungsfindung in der täglichen Praxis erleichtert werden. Hierzu entwickelten Sperduto et al. 2012 den diagnosespezifischen Graded prognostic assesement Score (DS-GPA). Gegenstand dieser Arbeit ist die Etablierung der Registerstudie „prospektive Evaluation des DS-GPA“ (PEGPA), welcher auf retrospektiven Daten basiert. Es wurde ein Studienprotokoll entwickelt sowie eine Matrix zur Dokumentation und Auswertung angefertigt. Ein statistischer Test zur Beurteilung der Prognoseschätzung wurde gestaltet. Die Durchführung und Anwendung soll anhand einer Zwischenerhebung der ersten 30 Patienten demonstriert werden. Die Datenerhebung und -dokumentation zur Ermittlung des korrekten DS-GPA Index verlief problemlos. Mittels des oben genannten Tests wurde die Prognoseschätzung nur bei 5 von 28 Patienten als zuverlässig bewertet. Die Ergebnisse dieser Arbeit können als Grundlage für die Fortführung der Registerstudie angesehen werden. Das Register kann aufgrund der zuverlässigen Datendokumentation als Qualitätssicherungsinstrument dienen. Die Ergebnisse der Zwischenauswertung können die Relevanz der Prognoseschätzung mittels DS-GPA in der täglichen Praxis nicht stützen. Obwohl eindeutig mehr Daten mithilfe des PEGPA-Registers gesammelt werden müssen, scheinen die Ergebnisse darauf hinzuweisen, dass die Fortschritte in der systemischen Tumortherapie, wie zielgerichtete und Immuntherapien, ebenso wie die stereotaktische Strahlentherapie dazu beitragen die Anwendbarkeit des DS-GPA als Prognosescore für hirnmetastasierte Patienten einzuschränken.

description: By observing 1026 samples of MSMEs in Indonesia, this study tries to answer whether factors related to assistance policies of the government in the case of Indonesia affect the sustainability performance and recovery of MSMEs during the pandemic crisis. This research also highlighted the mediating role of perceived policy effectiveness amid the relationship between policy-related factors and sustainability performance. Data analysis was carried out using the PLS-SEM technique with a CFA approach through SMARTPLS 3.3.0, which was collected by purposive sampling. The results show that capital support from the government affects both direct and indirect sustainability performance via the mediating role of perceived policy effectiveness. Meanwhile, preferential policies of the bank and the part of professional associations only affect sustainability performance via mediating role of policy effectiveness. In contrast, the tax-supporting policy has no significant effect on sustainability performance either directly or indirectly. Finally, sustainable competitive performance significantly positively affected the survival-recovery of MSMEs

description: Exciton-polaritons are hybrid light-matter quasiparticles formed by strongly interacting photons and excitons (electron-hole pairs) in semiconductor microcavities. They have emerged as a robust solid-state platform for next-generation optoelectronic applications as well as fundamental studies of quantum many-body physics. Importantly, exciton-polaritons are a profoundly open (i.e., non-Hermitian) quantum system: it requires constant pumping of energy and continuously decays releasing coherent radiation. Thus, the exciton-polaritons always exist in a balanced potential landscape of gain and loss. However, the inherent non-Hermitian nature of this potential has so far been largely ignored in exciton-polariton physics. Here we demonstrate that non-Hermiticity dramatically modifies the structure of modes and spectral degeneracies in exciton-polariton systems, and, therefore, will affect their quantum transport, localisation, and dynamical properties. Using a spatially-structured optical pump, we create a chaotic exciton-polariton billiard. Eigenmodes of this billiard exhibit multiple non-Hermitian spectral degeneracies -- exceptional points. These are known to cause remarkable wave phenomena, such as unidirectional transport, anomalous lasing/absorption, and chiral modes. By varying parameters of the billiard, we observe crossing and anti-crossing of energy levels and reveal the nontrivial topological modal structure exclusive to non-Hermitian systems. We also observe the mode switching and topological Berry phase for a parameter loop encircling the exceptional point. Our findings pave the way for studies of non-Hermitian quantum dynamics of exciton-polaritons, which can lead to novel functionalities of polariton-based devices.

description: INTRODUCTION: Practice facilitation involves trained individuals working with practice staff to conduct quality improvement activities and support delivery of evidence-based clinical services. We examined the feasibility of using practice facilitation to assist federally qualified health centers (FQHCs) to increase colorectal cancer screening rates in North Carolina.

METHODS: The intervention consisted of 12 months of facilitation in 3 FQHCs. We conducted chart audits to obtain data on changes in documented recommendation for colorectal cancer screening and completed screening. Key informant interviews provided qualitative data on barriers to and facilitators of implementing office systems.

RESULTS: Overall, the percentage of eligible patients with a documented colorectal cancer screening recommendation increased from 15% to 29% (P < .001). The percentage of patients up to date with colorectal cancer screening rose from 23% to 34% (P = .03). Key informants in all 3 clinics said the implementation support from the practice facilitator was critical for initiating or improving office systems and that modifying the electronic medical record was the biggest challenge and most time-consuming aspect of implementing office systems changes. Other barriers were staff turnover and reluctance on the part of local gastroenterology practices to perform free or low-cost diagnostic colonoscopies for uninsured or underinsured patients.

CONCLUSION: Practice facilitation is a feasible, acceptable, and promising approach for supporting universal colorectal cancer screening in FQHCs. A larger-scale study is warranted.

description: We present an algorithm that computes the multipole coefficients of the galaxy three-point correlation function (3PCF) without explicitly considering triplets of galaxies. Rather, centering on each galaxy in the survey, it expands the radially-binned density field in spherical harmonics and combines these to form the multipoles without ever requiring the relative angle between a pair about the central. This approach scales with number and number density in the same way as the two-point correlation function, allowing runtimes that are comparable, and 500 times faster than a naive triplet count. It is exact in angle and easily handles edge correction. We demonstrate the algorithm on the LasDamas SDSS-DR7 mock catalogs, computing an edge corrected 3PCF out to $90\;{\rm Mpc}/h$ in under an hour on modest computing resources. We expect this algorithm will render it possible to obtain the large-scale 3PCF for upcoming surveys such as Euclid, LSST, and DESI.

description: Let $X$ be a smooth complete curve, $G$ be a reductive group and $P\subset G$ a parabolic. Following Drinfeld, one defines a compactification $\widetilde{\on{Bun}}_P$ of the moduli stack of $P$-bundles on $X$. The present paper is concerned with the explicit description of the Intersection Cohomology sheaf of $\widetilde{\on{Bun}}_P$. The description is given in terms of the combinatorics of the Langlands dual Lie algebra $\check{\mathfrak g}$.

description: We construct an involution on set partitions which keeps track of the numbers of crossings, nestings and alignments of two edges. We derive then the symmetric distribution of the numbers of crossings and nestings in partitions, which generalizes Klazar's recent result in perfect matchings. By factorizing our involution through bijections between set partitions and some path diagrams we obtain the continued fraction expansions of the corresponding ordinary generating functions.
