description: To elucidate the mechanisms of cellular mechanotransduction, it is necessary to employ biomaterials that effectively merge biofunctionality with appropriate mechanical characteristics. Agarose is a standard biopolymer used in cartilage mechanobiology but lacks necessary adhesion motifs for cell-matrix interactions to complete mechanostransduction studies. Collagen type I is a natural biomaterial used in cartilage mechanotransduction studies but creates an environment much softer than native cartilage tissue. In these studies, agarose was blended at two final concentrations (2% w/v and 4% w/v) with collagen type I (2 mg/mL). The overarching goal was to determine whether a composite hydrogel of agarose and collagen can create a mechanically and biologically suitable matrix for chondrocyte studies. First, hydrogels were characterized by rheologic and compressive properties, contraction, and structural homogeneity. Following baseline characterization, primary murine chondrocytes were embedded (1 × 106 cells/mL) within the hydrogels to assess the longer-term in vitro impact on matrix mechanics, cell proliferation, sulfated glycosaminoglycan (sGAG) content, and cellular morphology. To begin probing questions about physiologic loading conditions that chondrocytes experience in vivo, a custom compression loading system was validated using cell-laden hydrogels. Briefly, the 4% agarose – 2 mg/mL collagen I hydrogel composites were able to retain chondrocyte morphology over 21 days in culture, resulted in continual sGAG production, and had bulk mechanics similar to that of the stiffest hydrogel material tested, indicating this hydrogel class may be promising towards developing an effective hydrogel for chondrocyte mechanotransduction and mechanobiology studies, a critical step towards a fuller understanding of cell-matrix interactions.

description: Despite the importance of sparsity signal models and the increasing prevalence of high-dimensional streaming data, there are relatively few algorithms for dynamic filtering of time-varying sparse signals. Of the existing algorithms, fewer still provide strong performance guarantees. This paper examines two algorithms for dynamic filtering of sparse signals that are based on efficient l1 optimization methods. We first present an analysis for one simple algorithm (BPDN-DF) that works well when the system dynamics are known exactly. We then introduce a novel second algorithm (RWL1-DF) that is more computationally complex than BPDN-DF but performs better in practice, especially in the case where the system dynamics model is inaccurate. Robustness to model inaccuracy is achieved by using a hierarchical probabilistic data model and propagating higher-order statistics from the previous estimate (akin to Kalman filtering) in the sparse inference process. We demonstrate the properties of these algorithms on both simulated data as well as natural video sequences. Taken together, the algorithms presented in this paper represent the first strong performance analysis of dynamic filtering algorithms for time-varying sparse signals as well as state-of-the-art performance in this emerging application.

description: We report on the response of microchannel plates (MCPs) to single relativistic particles and to electromagnetic showers. Particle detection by means of secondary emission of electrons at the MCP surface has long been proposed and is used extensively in ion time-of-flight mass spectrometers. What has not been investigated in depth is their use to detect the ionizing component of showers. The time resolution of MCPs exceeds anything that has been previously used in calorimeters and, if exploited effectively, could aid in the event reconstruction at high luminosity colliders. Several prototypes of photodetectors with the amplification stage based on MCPs were exposed to cosmic rays and to 491 MeV electrons at the INFN-LNF Beam-Test Facility. The time resolution and the efficiency of the MCPs are measured as a function of the particle multiplicity, and the results used to model the response to high-energy showers.

description: Histone deacetylase inhibitors (HDACi) have proven to induce HIV-RNA and antigen expression in resting CD4 T cells of antiretroviral therapy (ART)-treated HIV-infected individuals. However, to achieve viral eradication, immune clearance must follow latency reversal, and thus it is essential to understand the impact of latency reversal agents on immune function.Design:Here we evaluate the impact of in-vivo administration of vorinostat (VOR) and panobinostat (PNB) during clinical trials on natural killer (NK) cell function and phenotype.Methods:Cryopreserved peripheral blood mononuclear cells from HIV-positive participants receiving VOR (NCT01319383) or PNB (NCT01680094) were selected to assess the impact of the drugs on cell composition, activation, NK cell phenotype (CD16, NKG2D, NKp30, NKp46 and DNAM-1), cytotoxic activity (CD107a), and interferon (IFN)-γ production.Results:No impairment of NK cell function was observed during treatment with either VOR or PNB. An increase in the frequency of CD3-CD56 NK cells was consistently observed. Interestingly, after VOR administration, NK cells increased expression of NKp46 and CD16, and showed improved degranulation and IFN-γ production capacity. Moreover, taking together VOR and PNB samples, HIV DNA levels in CD4 cells were negatively correlated with NK cell frequency and NK cell expression of CD16.Conclusions:In-vivo treatment with HDACi does not have measurable negative effects on NK cell function, with some evidence of improved function in vitro. These results have important implications for potential combinatorial approaches to target HIV reservoirs, suggesting that the use of HDACis as a latency reversal agent could be paired with interventions to enhance NK cell activity or recruitment.

description: The initial synthesis and characterization of a new family of amido-bis(amidate) early transition metal compounds has lead to the development of a new class of 1,1’-dicarbodiimidoferrocene proligands. These proligands and related 2,4-diimino-1,3-diazetidine compounds are useful precursors for 1,1’-bis(guanidinate)ferrocene early transition metal complexes exhibiting novel reactivity. Additionally, 1,1’-dicarbodiimidoferrocenes can be utilized, in the form of boramidinates, to study the reactivity of boramidinate frustrated Lewis pairs with boranes, CO, CO2 and other small molecules.

description: Current strategies aimed to cure HIV infection are based on combined efforts to reactivate the virus from latency and improve immune effector cell function to clear infected cells. These strategies are primarily focused on CD8+ T cells and approaches are challenging due to insufficient HIV antigen production from infected cells and poor HIV-specific CD8+ T cells. γδ T cells represent a unique subset of effector T cells that can traffic to tissues, and selectively target cancer or virally infected cells without requiring MHC presentation. We analyzed whether γδ T cells represent a complementary/alternative immunotherapeutic approach towards HIV cure strategies. γδ T cells from HIV-infected virologically suppressed donors were expanded with bisphosphonate pamidronate (PAM) and cells were used in autologous cellular systems ex vivo. These cells (a) are potent cytotoxic effectors able to efficiently inhibit HIV replication ex vivo, (b) degranulate in the presence of autologous infected CD4+ T cells, and (c) specifically clear latently infected cells after latency reversal with vorinostat. This is the first proof of concept to our knowledge showing that γδ T cells target and clear autologous HIV reservoirs upon latency reversal. Our results open potentially new insights into the immunotherapeutic use of γδ T cells for current interventions in HIV eradication strategies.

Coercive and catalytic strategies for promoting human rights : state violence and the composition of foreign aid

description: There is tremendous variation in whether and how donors respond to severe human rights violations using foreign aid. Donors that respond choose between two strategic options: coercion, which uses aid and the threat of withdrawal as material leverage to influence recipient leaders' behaviors, and catalysis, which uses aid for developing political systems in the recipient country to limit state violence from within. Once a donor decides to respond, what determines its strategic choices? I argue that three factors help to answer this question: (1) how exposed the donor's interests are to problems stemming from human rights violations, (2) how costly each strategy would be to the donor, and (3) whether the recipient is willing to pay the costs of pursuing outside options to obtain development finance. I use Tobit models to estimate how donor interests moderate the relationship between state violence and aid to economic and governance sectors from all OECD donors to all eligible recipients from 2003-2018. I find that donors typically prioritize catalytic strategies during this time period, but substitute coercive strategies when political liberalization would be difficult to achieve or undesirable from the donor's perspective. To estimate how donors respond to recipients' outside options for development finance, I use doubly robust difference-in-differences estimator with multiple treatments to investigate how recipients signing Belt and Road Initiative (BRI) agreements with China affect donors' strategy. I find that when recipients signal that they are willing and able to bypass OECD donors' coercive punishments, these donors further increase their reliance on catalytic strategies for promoting human rights. This has implications for understanding the relationship between human rights and foreign aid. Donors do not consistently rely on political conditionalities as leverage over leaders' policy decisions and typically attempt to strengthen and liberalize the domestic political environment for human rights in recipient states. When this is too costly for donors, they rely on coercive strategies. However, coercive strategy is under threat. Developing countries have access to a wider range of funding sources than in past decades, allowing them to access development finance without political conditionalities. Donors respond to these outside options by increasing their reliance on catalytic strategy, suggesting that donors are pursuing political liberalization in increasingly difficult environments.

description: This paper develops a method to learn optimal controls from data for bilinear systems without a priori knowledge of the system dynamics. Given an unknown bilinear system, we first characterize when the available data is suitable to solve the optimal control problem. This characterization leads us to propose an online control experiment design procedure that guarantees that any input/state trajectory can be represented as a linear combination of collected input/state data matrices. Leveraging this data-based representation, we transform the original optimal control problem into an equivalent data-based optimization problem with bilinear constraints. We solve the latter by iteratively employing a convex-concave procedure to convexify it and find a locally optimal control sequence. Simulations show that the performance of the proposed data-based approach is comparable with model-based methods.

description: Current efforts toward human immunodeficiency virus (HIV) eradication include approaches to augment immune recognition and elimination of persistently infected cells following latency reversal. Natural killer (NK) cells, the main effectors of the innate immune system, recognize and clear targets using different mechanisms than CD8+ T cells, offering an alternative or complementary approach for HIV clearance strategies. We assessed the impact of interleukin 15 (IL-15) treatment on NK cell function and the potential for stimulated NK cells to clear the HIV reservoir. We measured NK cell receptor expression, antibody-dependent cell-mediated cytotoxicity (ADCC), cytotoxicity, interferon gamma (IFN-γ) production, and antiviral activity in autologous HIV replication systems. All NK cell functions were uniformly improved by IL-15, and, more importantly, IL-15-treated NK cells were able to clear latently HIV-infected cells after exposure to vorinostat, a clinically relevant latency-reversing agent. We also demonstrate that NK cells from HIV-infected individuals aviremic on antiretroviral therapy can be efficiently stimulated with IL-15. Our work opens a promising line of investigation leading to future immunotherapies to clear persistent HIV infection using NK cells.

description: Tolerance is a diagnostic criterion for alcohol use disorder (AUD) and dependence and is often measured metabolically or behaviorally by comparing blood ethanol concentrations (BEC) or locomotor performance to an ethanol (EtOH) challenge before and after a drinking history, respectively. To explore another aspect of chronic behavioral tolerance in a family history positive (FH+) model of AUD, crossed High Alcohol Preferring (cHAP) mice were allowed to respond instrumentally for an EtOH reinforcer after either a five-week history of continuous home cage two-bottle choice (2BC) drinking or a concurrent five-week water-drinking period. Additionally, some of these animals were placed back into the operant box after home cage drinking histories to respond in extinction, allowing for the quantification of alcohol-motivated seeking alone in the absence of EtOH taking and its intoxicating effects. The results demonstrate that an alcohol history does not lead to a subsequent increase in active lever responding or inactive lever responding when compared to water-drinking controls. However, female cHAP mice with an EtOH-drinking history respond more on the inactive lever in extinction compared to water controls, suggesting that home cage EtOH history potentiates variation in responding in extinction. Overall, female mice responded more on the active lever and drank more alcohol in the reinforced condition, but again, there was not an effect of drinking history on this sex-specific effect. Together these results suggest that while female cHAPs, regardless of drinking history, are more motivated to work to drink EtOH, reinforced and non-reinforced instrumental responding are not reliable readouts for tolerance in cHAP mice compared to other endpoints such as drinking in the dark (DID) assays.

description: The interplay of the non-equivalent corners in the Brillouin zone of transition metal dichalcogenides have been investigated extensively. While experimental and theoretical works contributed to a detailed understanding of the relaxation of selective optical excitations and the related relaxation rates, only limited microscopic descriptions of stationary experiments are available so far. In this manuscript we present microscopic calculations for the non-equilibrium steady state properties of excitons during continuous wave pumping. We find sharp features in photoluminescence excitation spectra and degree of polarization which result from phonon assisted excitonic transitions dominating over exciton recombination and intervalley exchange coupling.

description: In computer vision, some attribution methods for explaining CNNs attempt to study how the intermediate features affect the network prediction. However, they usually ignore the feature hierarchies among the intermediate features. This paper introduces a hierarchical decomposition framework to explain CNN's decision-making process in a top-down manner. Specifically, we propose a gradient-based activation propagation (gAP) module that can decompose any intermediate CNN decision to its lower layers and find the supporting features. Then we utilize the gAP module to iteratively decompose the network decision to the supporting evidence from different CNN layers. The proposed framework can generate a deep hierarchy of strongly associated supporting evidence for the network decision, which provides insight into the decision-making process. Moreover, gAP is effort-free for understanding CNN-based models without network architecture modification and extra training process. Experiments show the effectiveness of the proposed method. The code and interactive demo website will be made publicly available.

description: Items shared through Social Media may affect more than one user's privacy --- e.g., photos that depict multiple users, comments that mention multiple users, events in which multiple users are invited, etc. The lack of multi-party privacy management support in current mainstream Social Media infrastructures makes users unable to appropriately control to whom these items are actually shared or not. Computational mechanisms that are able to merge the privacy preferences of multiple users into a single policy for an item can help solve this problem. However, merging multiple users' privacy preferences is not an easy task, because privacy preferences may conflict, so methods to resolve conflicts are needed. Moreover, these methods need to consider how users' would actually reach an agreement about a solution to the conflict in order to propose solutions that can be acceptable by all of the users affected by the item to be shared. Current approaches are either too demanding or only consider fixed ways of aggregating privacy preferences. In this paper, we propose the first computational mechanism to resolve conflicts for multi-party privacy management in Social Media that is able to adapt to different situations by modelling the concessions that users make to reach a solution to the conflicts. We also present results of a user study in which our proposed mechanism outperformed other existing approaches in terms of how many times each approach matched users' behaviour.

description: Recycling valuable cathode material from end-of-life (EOL) Li-ion batteries (LIBs) is essential to preserve raw material depletion and environmental sustainability. Direct recycling reclaims the cathode material without jeopardizing its original functional structures and maximizing return values from spent LIBs compared to other regeneration processes. This work employed two chemically delithiated lithium cobalt oxide (LCO) cathodes at different states of health (SOH), which are analogous to the spent cathodes but free of any impurities, to investigate the effectiveness of cathode regeneration. The material and electrochemical properties of both delithiated SOHs were systematically examined and compared to pristine LCO cathode. Further, those model materials were regenerated by a hydrothermal-based approach. The direct cathode regeneration of both low and high SOH cathode samples restored their reversible capacity and cycle performance comparable to pristine LCO cathode. However, the inferior performance observed in higher current density (2C) rate was not comparable to pristine LCO. In addition, the higher resistance of regenerated cathodes is attributed to lower high-rate performance, which was pointed out as the key challenge of the cathode recycling process. This study provides valuable knowledge about the effectiveness of cathode regeneration by investigating how the disordered, lithium-deficient cathode at different SOH from spent EOL batteries are rejuvenated without changing any material and electrochemical functional properties.

description: Chameleon plant (Houttuynia cordata Thunb.) is native to Southern and Southeastern Asia. It can reproduce sexually through seeds and asexually through rhizomes and is invasive in multiple countries including the U.S. There has been much research on H. cordata as a medicinal species, and its potential as an invasive species is well documented. However, its herbicidal resistance has not previously been quantified. The objective of this study is to assess H. cordata’s resistance to herbicides. This study consisted of two rounds of tests to examine the resistance of H. cordata plants to three commonly used herbicides: SpeedZone, Weed-B-Gon, and Roundup. Two concentrations of each herbicide were used during each trial in the study: the recommended concentration and twice the recommended concentration. Herbicide treatments were applied outside the greenhouse. Herbicides were sprayed uniformly on the plants until the herbicide was dripping off the leaves. The growth of the treated plants was then monitored in the greenhouse. The herbicides generally reduced growth of the plants temporarily. However, plant extermination was not achieved. Plant samples from all herbicidal treatments regrew from rhizomes after all herbicide treatments. Results from the study showed that H. cordata could not be controlled by the recommended concentrations of herbicides commercially available for horticultural uses in the U.S. Doubling the recommended herbicide concentration was also ineffective in exterminating H. cordata plants. This research clearly showed that H. cordata has the potential to become a highly invasive species with the potential to negatively affect the ecological integrity of many communities in the U.S.

description: Einer der Gründe zur Untersuchung interplanetarer Staubteilchen liegt darin, daß die Hauptmasse des jährlichen extraterrestrischen Eintrages auf die Erde in er Form kleiner Staubteilchen, eben dieses kosmischen Staubes, erfolgt. Ungefähr 40 000 bis 60 000 Tonnen von Staubteilchen in der Größe von 10 µm bis 1 mm gehen pro Jahr auf die Atmosphäre der Erde nieder. Dagegen ist der Eintrag von Meteoriten im Massenbereich von Kilogramm bis Tonnen zu vernachlässigen. Da die Staubteilchen im wesentlichen frei von Auswahleffekten von allen kleineren Körpern im Sonnensystem kommen können, nimmt man an, daß sie uns einen besseren Überblick über die Zusammensetzung von Asteoriden und Kometen geben können, im Vergleich zu den Meteoriten. Meteoriten stammen sehr wahrscheinlich nur von rel. wenigen Körpern die sich in bahndynamisch günstigen Positionen befinden um Bruchstücke auf die Erde zu sendne. Traditionell werden zwei Obergruppen kosmischen Staubes unterschieden: interplanetare Staubteilchen, von 5- 50 µm Größe, die mit Hilfe von Flugzeugen eingefangen werden, und Mikrometeoriten, von 50 - 500 µm Größe, die z.B. in der Antarktis und in Grönland aus dem Eis geborgen werden. Die größeren Teilchen werden beim Eintritt in die Erdatmosphäre stärker erhitzt und daher z.T. stärker umgewandelt im Vergleich zu den kleineren Stäuben, deshalb mach man sich die Mühe die 10 µm großen Partikel mit verschiedensten analytischen Methoden nacheinander zu untersuchen (SEM, INAA, SXRF, PIXE, SIMS, TOF-SIMS, TEM). Im Rahmen der vorliegenden Arbeit wurden Vertreter beider Größenklassen untersucht um Fragen zur Klassifizierung, zur Mineralogie, zur chemischen Zusammensetzung, zur Herkunft und zur thematischen Beeinflussung durch den Eintritt in die Erdatmosphäre zu klären.

description: AGS-004 consists of matured autologous dendritic cells co-electroporated with in vitro transcribed RNA encoding autologous HIV antigens. In an open-label, single arm sub-study of AGS-004-003, AGS-004 was administered monthly to suppressed participants who started antiretroviral therapy (ART) during acute HIV infection. HIV-1 specific T cell responses were measured by multicolor flow cytometry after 3-4 doses. The frequency of resting CD4+ T-cell infection (RCI) was measured by quantitative viral outgrowth assay. Participants demonstrating increased immune response postvaccination were eligible for analytic treatment interruption (ATI). AGS-004 induced a positive immune response defined as ≥2-fold increase from baseline in the number of multifunctional HIV-1 specific CD28+/CD45RA- CD8+ effector/memory cytoxic T-lymphocytes (CTLs) in all six participants. All participants underwent ATI with rebound viremia at a median of 29 days. Immune correlates between time to viral rebound and the induction of effector CTLs were determined. Baseline RCI was low in most participants (0.043-0.767 IUPM). One participant had a >2-fold decrease (0.179-0.067 infectious units per million [IUPM]) in RCI at week 10. One participant with the lowest RCI had the longest ATI. AGS-004 dendritic cell administration increased multifunctional HIV-specific CD28+/CD45RA- CD8+ memory T cell responses in all participants, but did not permit sustained ART interruption. However, greater expansion of CD28-/CCR7-/CD45RA- CD8+ effector T cell responses correlated with a longer time to viral rebound. AGS-004 may be a useful tool to augment immune responses in the setting of latency reversal and eradication strategies.

description: Die vorliegende Arbeit stellt die Ergebnisse der petrologischen und geochemischen Analyse von laténezeitlicher Verhüttungsschlacken, metallischen Verhüttungsprodukten, Teilen von Ofenwandungen, Sedimentgesteinsfragmenten und möglichen Zuschlagsstoffen vor. Diese fünf verschiedenen Probetypen wurden aufgrund ihrer äußeren Erscheinung und Ausbildungsform unterteilt. Die Proben stammen aus Pößneck, einer Kleinstadt im Saale-Orla-Kreis in Thüringen, und wurden 1999 bei einer archäologischen Grabung zusammen mit weiteren archäologischen Artefakten freigelegt. Um mehr Informationen über die Verhüttungsschlacken, die mögliche Herkunft ihrer Edukte und den Zusammenhang zu den anderen vier Probetypen zu erhalten, wurden die Fundstücke unter petrologischen und geochemischen Gesichtspunkten bearbeitet. Die Proben wurden zuerst makroskopisch auf ihre äußerlichen Merkmale und Besonderheiten hin beschrieben. Ein weiterer Schritt war die polarisationsmikroskopische Analyse und Beschreibung, durch die der Phasenbestand ermittelt wurde. Ebenfalls zur Phasenanalyse diente die Rasterelektronenmikroskopie (REM) und die Röntgendiffraktometrie (XRD). Mittels energiedispersiver Röntgenanalyse (EDX) und semiquantitativer Mikroanalytik wurden lichtoptisch schwer erkennbare oder von opaken Phasen verdeckte Minerale identifiziert. Zur Ermittlung der Gesamtchemie wurden die Probestücke mittels Röntgenfluoreszenzanalyse (RFA) semiquantitativ untersucht. Bei den Analysen stellte sich heraus, dass der für die Verhüttungsschlacken typische Phasenbestand überwiegend Fayalit (Fe2SiO), Magnetit (Fe3O4), Wüstit (FexO) und Leucit (KalSi2O6) beinhaltet. Die Ofenwandungen und Sedimentfragmente bestehen zumeist aus Quarz (SiO2), wobei die Sedimentfragmente zusätzlich einen größeren Anteil Kalzit (CaCO3) beinhalten. In den metallischen Verhüttungsprodukten konnten vorwiegend Kupfer und Kupfer-(Eisen-)Sulfide ermittelt werden. Der typische Phasenbestand der Zuschlagstoffe beschränkt sich auf Kalzit (CaCO3) und wenig Hämatit (Fe2O3). Weiterhin wurden deutliche geochemische Unterschiede zwischen den unterschiedlichen Probetypen ermittelt, besonders im FeO-, CaO- und SiO2-Gehalt. Es wurden darüber hinaus auch verhüttungstechnische Zusammenhänge zwischen den verschiedenen Probetypen erkennbar. So konnten die Ofenwandungen kontaminierende Eigenschaften in Bezug auf den SiO2- und Al2O3-Gehalt nachgewiesen werden. Hämatit, Kalzit und Baryt wurden als Zuschlagstoffe bestätigt. Darüber hinaus wurden unter Berücksichtigung der heutigen Lagerstättensituation in Thüringen und von Informationen zum laténezeitlichen Bergbau im Raum Thüringen Vermutungen in Bezug zur Herkunft des verhütteten Erzes getroffen. Der laténezeitliche Verhüttungsprozess konnte rekonstruiert werden.

description: We develop semantics and syntax for bicategorical type theory. Bicategorical type theory features contexts, types, terms, and directed reductions between terms. This type theory is naturally interpreted in a class of structured bicategories. We start by developing the semantics, in the form of comprehension bicategories. Examples of comprehension bicategories are plentiful; we study both specific examples as well as classes of examples constructed from other data. From the notion of comprehension bicategory, we extract the syntax of bicategorical type theory, that is, judgment forms and structural inference rules. We prove soundness of the rules by giving an interpretation in any comprehension bicategory. The semantic aspects of our work are fully checked in the Coq proof assistant, based on the UniMath library.

description: Knowledge bases (KB) are an important resource in a number of natural language processing (NLP) and information retrieval (IR) tasks, such as semantic search, automated question-answering etc. They are also useful for researchers trying to gain information from a text. Unfortunately, however, the state-of-the-art in Sanskrit NLP does not yet allow automated construction of knowledge bases due to unavailability or lack of sufficient accuracy of tools and methods. Thus, in this work, we describe our efforts on manual annotation of Sanskrit text for the purpose of knowledge graph (KG) creation. We choose the chapter Dhanyavarga from Bhavaprakashanighantu of the Ayurvedic text Bhavaprakasha for annotation. The constructed knowledge graph contains 410 entities and 764 relationships. Since Bhavaprakashanighantu is a technical glossary text that describes various properties of different substances, we develop an elaborate ontology to capture the semantics of the entity and relationship types present in the text. To query the knowledge graph, we design 31 query templates that cover most of the common question patterns. For both manual annotation and querying, we customize the Sangrahaka framework previously developed by us. The entire system including the dataset is available from https://sanskrit.iitk.ac.in/ayurveda/ . We hope that the knowledge graph that we have created through manual annotation and subsequent curation will help in development and testing of NLP tools in future as well as studying of the Bhavaprakasanighantu text.

description: We study the entanglement in tripartite quantum systems by using the principal basis matrix representations of density matrices. Using the Schmidt decomposition and local unitary transformation, we first convert the general states to simpler forms and then construct some special matrices from the correlation tensors of the simplified density matrices. Based on the different linear combinations of these matrices, necessary conditions are presented to detect entanglement of tripartite states. Detailed examples show that our method can detect more entangled states than previous ones.

description: Sterile neutrinos of keV masses are one of the most promising candidates for the warm dark matter, which could solve the small-scale problems encountered in the scenario of cold dark matter. We present a detailed study of the production of such sterile neutrinos in a supernova core, and derive stringent bounds on the active-sterile neutrino mixing angles and sterile neutrino masses based on the standard energy-loss argument.
