description: We consider the production and decay of selectrons and charginos in $e^-e^-$ collisions. The advantage over usual $e^+e^-$ collisions is the very low level of standard model backgrounds which should make the discovery of selectrons or charginos relatively straightforward. The use of polarized beams provides an additional powerful tool to determine the supersymmetry parameters.

description: We consider the problem in regression analysis of identifying subpopulations that exhibit different patterns of response, where each subpopulation requires a different underlying model. Unlike statistical cohorts, these subpopulations are not known a priori; thus, we refer to them as cadres. When the cadres and their associated models are interpretable, modeling leads to insights about the subpopulations and their associations with the regression target. We introduce a discriminative model that simultaneously learns cadre assignment and target-prediction rules. Sparsity-inducing priors are placed on the model parameters, under which independent feature selection is performed for both the cadre assignment and target-prediction processes. We learn models using adaptive step size stochastic gradient descent, and we assess cadre quality with bootstrapped sample analysis. We present simulated results showing that, when the true clustering rule does not depend on the entire set of features, our method significantly outperforms methods that learn subpopulation-discovery and target-prediction rules separately. In a materials-by-design case study, our model provides state-of-the-art prediction of polymer glass transition temperature. Importantly, the method identifies cadres of polymers that respond differently to structural perturbations, thus providing design insight for targeting or avoiding specific transition temperature ranges. It identifies chemically meaningful cadres, each with interpretable models. Further experimental results show that cadre methods have generalization that is competitive with linear and nonlinear regression models and can identify robust subpopulations.

description: In the framework of the stochastic projected Gross-Pitaevskii equation we investigate finite-temperature dynamics of a bosonic Josephson junction (BJJ) formed by a Bose-Einstein condensate of atoms in a two-well trapping potential. We extract the characteristic properties of the BJJ from the stationary finite-temperature solutions and compare the dynamics of the system with the resistively shunted Josephson model. Analyzing the decay dynamics of the relative population imbalance we estimate the effective normal conductance of the junction induced by thermal atoms. The calculated normal conductance at various temperatures is then compared with predictions of the noise-less model and the model of ballistic transport of thermal atoms.

Subjects: subject: Differential Geometry (math.DG)

description: We introduce a class of almost homogeneous varieties contained in the class of spherical varieties and containing horospherical varieties as well as complete symmetric varieties. We develop K{ä}hler geometry on these varieties, with applications to canonical metrics in mind, as a generalization of the Guillemin-Abreu-Donaldson geometry of toric varieties. Namely we associate convex functions with hermitian metrics on line bundles, and express the curvature form in terms of this function, as well as the corresponding Monge-Amp{è}re volume form and scalar curvature. We then provide an expression for the Mabuchi functional and derive as an application a combinatorial sufficient condition of properness similar obtained by Li, Zhou and Zhu on group compactifications.

description: In this paper, we present an architecture and a formal framework to be used for systematic benchmarking of monitoring and diagnostic systems and for producing comparable performance assessments of different diagnostic technologies. The framework defines a number of standardized specifications, which include a fault catalog, a library of modular test scenarios, and a common protocol for gathering and processing diagnostic data. At the center of the framework are 13 benchmarking metric definitions. The calculation of metrics is illustrated on a probabilistic model-based diagnosis algorithms utilizing Bayesian reasoning techniques. The diagnosed system is a real-world electrical power system, namely the Advanced Diagnostics and Prognostics Testbed (ADAPT) developed and located at the NASA Ames Research Center. The proposed benchmarking approach shows how to generate realistic diagnostic data sets for large-scale, complex engineering systems, and how the generated experimental data can be used to enable "apples to apples" assessments of the effectiveness of different diagnostics and monitoring algorithms.
New algorithm in the variation after projection calculations for non-yrast nuclear states

description: We present a novel and simple algorithm in the variation after projection (VAP) approach for the non-yrast nuclear states. It is for the first time that the yrast state and non-yrast states can be varied on the same footing. The orthogonality among the calculated states is automatically fulfilled by solving the Hill-Wheeler equation. This avoids the complexity of the frequently used Gram-Schmidt orthogonalization, as adopted by the excited VAMPIR method. Thanks to the Cauchy's interlacing theorem in the matrix theory, the sum of the calculated lowest projected energies with the same quantum numbers can be safely minimized. Once such minimization is converged, all the calculated energies and the corresponding states can be obtained, simultaneously. The present VAP calculations are performed with time-odd Hartree-Fock Slater determinants. It is shown that the calculated VAP energies (both yrast and non-yrast) are very close to the corresponding ones from the full shell model calculations. It looks the present algorithm is not limited to the VAP, but should be universal, i.e., one can do the variation with different forms of the many-body wavefunctions to calculate the excited states in different quantum many-body systems.

description: This paper presents our design and development of a context-driven content adaptation planner, which dynamically transforms requested Web content into a proper format conforming to receiving contexts (e.g., access condition, network connection, and receiving device). Aiming to establish a semantic foundation for content adaptation, we apply description logics (DLs) to formally define context profiles and requirements and automate content adaptation decision. In addition, the computational overhead caused by content adaptation can be moderately decreased through the reduction of the size of adapted content
A single-shot measurement of the energy of product states in a translation invariant spin chain can replace any quantum computation

description: In measurement-based quantum computation, quantum algorithms are implemented via sequences of measurements. We describe a translationally invariant finite-range interaction on a one-dimensional qudit chain and prove that a single-shot measurement of the energy of an appropriate computational basis state with respect to this Hamiltonian provides the output of any quantum circuit. The required measurement accuracy scales inverse polynomially with the size of the simulated quantum circuit. This shows that the implementation of energy measurements on generic qudit chains is as hard as the realization of quantum computation. Here a ''measurement'' is any procedure that samples from the spectral measure induced by the observable and the state under consideration. As opposed to measurement-based quantum computation, the post-measurement state is irrelevant.

description: Threats from Africa undermine the security of Europe. The European Union and NATO have 22 member countries in common, namely most of EU member states. The fundamental role of the Atlantic Alliance is to safeguard the freedom and security of its member countries by political and military means. Since the fall of the Berlin Wall, non-state actors and hybrid threats emerged as the major challenges to international security. NATO is evolving in response to new strategic reality, and terrorism and weak states are among the most pressing challenges the Alliance faces. NATO is playing an increasingly important role in crisis management and peacekeeping. Since the African Union was established in 2001 as the successor to the Organization of African Unity,it faces difficulties in achieving the African ownership in peace and security. The chronic lack of funding and of appropriate military resources, makes the African Union depending on external aid –NATO provides military support, while the EU provides money. NATO cooperates with the AU since 2005, and all NATO-AU activities are coordinated with the EU. The NATO-EU partnership is complementar and mutual, and is based on common values and strategic interests, and should be strengthened to secure the European southern border, and to guarantee security in the Mediterranean region. Therefore, stronger and permanent NATO–EU partnership in Africa would be desirable. This brief paper investigates the ties between these three organizations, and suggests some recommendations to improve the 'trilateral' relationship to ensure security to their member states.

description: We consider the high-resolution imaging problem of 3D point source image recovery from 2D data using a method based on point spread function (PSF) engineering. The method involves a new technique, recently proposed by S.~Prasad, based on the use of a rotating PSF with a single lobe to obtain depth from defocus. The amount of rotation of the PSF encodes the depth position of the point source. Applications include high-resolution single molecule localization microscopy as well as the problem addressed in this paper on localization of space debris using a space-based telescope. The localization problem is discretized on a cubical lattice where the coordinates of nonzero entries represent the 3D locations and the values of these entries the fluxes of the point sources. Finding the locations and fluxes of the point sources is a large-scale sparse 3D inverse problem. A new nonconvex regularization method with a data-fitting term based on Kullback-Leibler (KL) divergence is proposed for 3D localization for the Poisson noise model. In addition, we propose a new scheme of estimation of the source fluxes from the KL data-fitting term. Numerical experiments illustrate the efficiency and stability of the algorithms that are trained on a random subset of image data before being applied to other images. Our 3D localization algorithms can be readily applied to other kinds of depth-encoding PSFs as well.

description: We study charge transport and fluctuations of the (3+1)-dimensional massive free Dirac theory. In particular, we focus on the steady state that emerges following a local quench whereby two independently thermalized halves of the system are connected and let to evolve unitarily for a long time. Based on the two-time von Neumann measurement statistics and exact computations, the scaled cumulant generating function associated with the charge transport is derived. We find that it can be written as a generalization of Levitov-Lesovik formula to the case in three spatial dimensions. In the massless case, we note that only the first four scaled cumulants are nonzero. Our results provide also a direct confirmation for the validity of the extended fluctuation relation in higher dimensions. An application of our approach to Lifshitz fermions is also briefly discussed.

description: VAPOR is an open-source, interactive 3D visualization and analysis platform developed by the NSF-National Center for Atmospheric Research. It was designed specifically to meet the advanced visualization needs of the geosciences community and operates primarily on 3D arrays of time-varying, gridded data arising from numerical simulations. It supports many of the commonly used file formats and computational meshes used in geosciences including layered curvilinear grids, layered unstructured grids, and Arakawa grids. It has advanced rendering capabilities such as Direct Volume Rendering and natively understands geo-referenced data with the ability to combine geo-referenced data from multiple datasets within the same scene [Li et al., 2019]. Since its initial release in 2007, VAPOR has had three significant updates and numerous minor releases expanding on the features driven primarily by the input from our user community. The recently released version 3.8 brings these advanced visualization capabilities to the Python ecosystem through the VAPOR python API. In this talk, we’ll provide an overview of VAPOR featuring the Python API and share how users can engage and contribute to the ongoing development efforts.

description: In minimal SUSY-GUT models with $M_{SUSY}\alt 1$ TeV, the renormalization group equations have a solution dominated by the infrared fixed point of the top Yukawa coupling. This fixed point predicts $m_t\simeq (200\; {\rm GeV})\sin β$; combined with the LEP results it excludes $m_t\alt 130$ GeV. For $m_t$ in the range 130--160 GeV, it predicts that the lightest scalar $h$ has mass 60--85 GeV (detectable at LEP\,II). At SSC/LHC, each of the five scalars $h$, $H$, $A$, $H^{\pm }$ may be detectable, but not all of them together; in one parameter region none would be detectable.

description: It has been conjectured that fermions minimally coupled to a Chern-Simons gauge field define a conformal field theory (CFT) that is level-rank dual to Chern-Simons gauged Wilson-Fisher Bosons. The CFTs in question admit relevant deformations parametrized by a real mass. When the mass deformation is positive, the duality of the two deformed theories has previously been checked in detail in the large $N$ limit by comparing explicit all orders results on both sides of the duality. In this paper we perform a similar check for the case of negative mass deformations. In this case the bosonic field condenses triggering the Higgs mechanism. The effective excitations in this phase are massive $W$ bosons. By summing all leading large $N$ graphs involving these $W$ bosons we find an all orders (in the 't Hooft coupling) result for the thermal free energy of the bosonic theory in the condensed phase. Our final answer perfectly matches the previously obtained fermionic free energy under the conjectured duality map.

description: Anthropomorphic framing of social robots is widely believed to facilitate human-robot interaction. In two subsequent studies, the impact of anthropomorphic framing was examined regarding the subjective perception of a robot and the willingness to donate money for this robot. In both experiments, participants received either an anthropomorphic or a functional description of a humanoid NAO robot prior to a cooperative task. Afterwards the perceived robot’s humanlike perception and the willingness to “save” the robot from malfunctioning were assessed (donation behavior). Surprisingly, the first study revealed a negative effect of anthropomorphic framing on the willingness to donate. This negative effect disappeared if the robot’s functional value for the task fulfillment was additionally made explicit (Study 2). In both studies, no effect of anthropomorphic framing on the humanlike perception of the robot was found. However, the behavioral results support the relevance of a functional awareness in social human-robot interaction.

description: We present a statistical-mechanical analysis of the positioning of nucleosomes along one of the chromosomes of yeast DNA as a function of the strength of the binding potential and of the chemical potential of the nucleosomes. We find a significant density of two-level nucleosome switching regions where, as a function of the chemical potential, the nucleosome distribution undergoes a "micro" first-order transition. The location of these nucleosome switches shows a strong correlation with the location of transcription-factor binding sites.

We find the $b \rightarrow s γ$ rate in ETC models with a GIM mechanism to be at most slightly larger than the standard model rate, whereas there is no significant extra model-independent contribution in other ETC scenarios. In the case of $B_s \rightarrow μ^+ μ^-$, ETC models with a GIM mechanism can yield a rate up to two orders of magnitude bigger than that of the standard model, whereas generic ETC scenarios are likely to give a rate which is about an order of magnitude bigger than that of the standard model.

description: The measurement of the triple Higgs coupling is a key benchmark for the LHC and future colliders. It directly probes the Higgs potential and its fundamental properties in connection to new physics beyond the Standard Model. There exist two phase space regions with an enhanced sensitivity to the Higgs self-coupling, the Higgs pair production threshold and an intermediate top pair threshold. We show how the invariant mass distribution of the Higgs pair offers a systematic way to extract the Higgs self-coupling, focusing on the leading channel $pp\to hh+X\to b\bar b\ γγ+X$. We utilize new features of the signal events at higher energies and estimate the potential of a high-energy upgrade of the LHC and a future hadron collider with realistic simulations. We find that the high-energy upgrade of the LHC to 27 TeV would reach a 5$σ$ observation with an integrated luminosity of 2.5 ab$^{-1}$. It would have the potential to reach 15% (30%) accuracy at the 68% (95%) confidence level to determine the SM Higgs boson self-coupling. A future 100 TeV collider could improve the self-coupling measurement to better than 5% (10%) at the 68% (95%) confidence level.

description: Although nanotoxicology studies have shown that respiratory exposure of titanium dioxide nanoparticles (TiO2 NPs) could induce adverse health effects, limited biomarkers associated with occupational exposure of TiO2 NPs were reported. The purpose of this study is to screen serum biomarkers among workers occupationally exposed to TiO2 NPs using metabolomics. Compared with the control group, a total of 296 serum metabolites were differentially expressed in the TiO2 NPs-exposed group, of which the relative expression of 265 metabolites increased, and the remaining 31 decreased. Three machine learning methods including random forest (RF), support vector machines (SVM), and boruta screened eight potential biomarkers and simultaneously selected a metabolite, Liquoric acid. Through multiple linear regression analysis to adjust the influence of confounding factors such as gender, age, BMI, smoking and drinking, occupational exposure to TiO2 NPs was significantly related to the relative expression of the eight potential biomarkers. Meanwhile, the receiver operating characteristic curves (ROCs) of these potential biomarkers had good sensitivity and specificity. These potential biomarkers were related to lipid peroxidation, and had biological basis for occupational exposure to TiO2 NPs. Therefore, it was demonstrated that the serum metabolites represented by Liquoric acid were good biomarkers of occupational exposure to TiO2 NPs.

description: La3Co4Sn13 is a superconducting material with transition temperature at Tc = 2.70 K, which presents a superlattice structural transition at T* ~ 150 K, a common feature for this class of compounds. However, for this material, it is not clear that at T* the lattice distortions arise from a charge density wave (CDW) or from a distinct microscopic origin. Interestingly, it has been suggested in isostructural non-magnetic intermetallic compounds that T* can be suppressed to zero temperature, by combining chemical and external pressure, and a quantum critical point is argued to be observed near these critical doping/pressure. Our study shows that application of pressure on single-crystalline La3Co4Sn13 enhances Tc and decreases T*. We observe thermal hysteresis loops for cooling/heating cycles around T* for P > 0.6 GPa, in electrical resistivity measurements, which are not seen in x-ray diffraction data. The hysteresis in electrical measurements may be due to the pinning of the CDW phase to impurities/defects, while the superlattice structural transition maintains its ambient pressure second-order transition nature under pressure. From our experiments we estimate that T* vanishes at around 5.5 GPa, though no quantum critical behavior is observed up to 2.53 GPa.

A Canonical Seed Assignment Model for Key Predistribution in Wireless Sensor Networks

description: A promising solution for trust establishment in wireless sensor networks is the assignment of cryptographic seeds (keys, secrets, etc.) to sensor nodes prior to network deployment, known as key predistribution. In this article, we propose a canonical seed assignment model for key predistribution characterizing seed assignment in terms of the probability distribution describing the number of nodes receiving each seed and the algorithm for seed assignment. In addition, we present a sampling framework for seed assignment algorithms in the canonical model. We propose a probabilistic k-connectivity model for randomly deployed secure networks using spatial statistics and geometric random graph theory.We analyze key predistribution schemes in the canonical model in terms of network connectivity and resilience to node capture. The analytical results can be used to determine the average or worst-case connectivity or resilience to node capture for a key predistribution scheme. Furthermore, we demonstrate the design of new key predistribution schemes and the inclusion of existing schemes in the canonical model. Finally, we present a general approach to analyze the addition of nodes to an existing secure network and derive results for a well-known scheme.
The impact of digital financial development on the green economy: An analysis based on a volatility perspective

description:
Without a doubt, green development is a consensus reached by most countries globally. However, detailed discussions on the impact of digital finance on green development remain scant among scholars. To address this gap, we first construct a Green Development Index for China. Utilizing provincial panel data from 2011 to 2019, we aim to evaluate the influence of digital finance on green development. Additionally, our research aimed to ascertain the ‘rebound’ effect of digital finance on green development, especially in terms of volatility. The results show that the development of digital finance has a positive impact on green development, but this impact is asymmetric, mainly exhibiting regional disparities and threshold effects. Moreover, digital finance can effectively suppress consumption volatility and the negative impact of green financial shocks on green development. Importantly, the smoothing effect of digital finance is particularly pronounced during downturn phases of the financial cycle. Further examination revealed the moderating roles of educational attainment, economic structure, R&D, and governmental intervention. Our findings underscore the pressing need for governmental authorities to prioritize economic transformation and R&D activities to amplify the synergistic benefits between digital finance and green growth. Concurrently, it's essential for governments to carefully evaluate their fiscal policies to ensure they do not inadvertently obstruct the path to sustainable green development.
Input-to-State Safety With Control Barrier Functions

Subjects: subject: Optimization and Control (math.OC)

description: This letter presents a new notion of input-to-state safe control barrier functions (ISSf-CBFs), which ensure safety of nonlinear dynamical systems under input disturbances. Similar to how safety conditions are specified in terms of forward invariance of a set, input-to-state safety (ISSf) conditions are specified in terms of forward invariance of a slightly larger set. In this context, invariance of the larger set implies that the states stay either inside or very close to the smaller safe set; and this closeness is bounded by the magnitude of the disturbances. The main contribution of the letter is the methodology used for obtaining a valid ISSf-CBF, given a control barrier function (CBF). The associated universal control law will also be provided. Towards the end, we will study unified quadratic programs (QPs) that combine control Lyapunov functions (CLFs) and ISSf-CBFs in order to obtain a single control law that ensures both safety and stability in systems with input disturbances.

description: The statistics of the field structure in the vortex core surrounding phase singularities in random wave fields are measured and calculated for diffusive and localized waves. Excellent agreement is found between experiment and theory. The variation of phase with geometric angle is deterministic, depending only upon the eccentricity of elliptical intensity contours, whose probability distribution is shown to be universal. The distribution of vorticity is shown to reflect both the vorticity distribution in the Gaussian limit and the mesoscopic distribution of total transmission.

description: Die Anfälligkeit der Nasennebenhöhlen für allergische und nicht-allergische Infektionen erschwert die Diagnose, da Symptome von Schleimhautverdickungen bis zu polypoiden Massen variieren. Bisherige manuelle Analysen sind ressourcenintensiv und führen zu Ermüdung der Kliniker. Ein computergestütztes Diagnoseverfahren (CAD) kann diesen Prozess optimieren. Während Deep Learning große Fortschritte in der medizinischen Bildanalyse gemacht hat, blieb die Erforschung paranasaler Anomalien bislang begrenzt. Diese Arbeit schlägt verschiedene Deep-Learning-Ansätze zur Klassifizierung von Kieferhöhlen-Opazitäten vor, darunter unüberwachtes Lernen, selbstüberwachtes Lernen und hybride Architekturen aus CNNs und Transformern.
description: The susceptibility of the paranasal sinuses to allergic and non-allergic infections complicates diagnosis as symptoms vary from mucosal thickening to polypoid masses. Previous manual analysis is resource intensive and leads to clinician fatigue. Computer-aided diagnosis (CAD) can optimize this process. While deep learning has made great strides in medical image analysis, the study of paranasal abnormalities has remained limited. This work proposes different deep learning approaches to classify maxillary sinus opacities, including unsupervised learning, self-supervised learning, and hybrid architectures of CNNs and transformers.

Levels of cerebrospinal fluid biomarkers total tau and phosphorylated tau do not predict survival time after diagnosis of Alzheimer’s disease – An 18-year follow-up

description: The current study aims to investigate whether pathological levels of total tau (T-tau) and/or phosphorylated tau (P-tau) can predict survival in Alzheimer's disease (AD).

Mortality in AD is complex and depends on many factors e.g., demographic and clinical. In this clinical-practice-based long-term study, almost half of the participants with AD had normal levels of tau. We found no clear results that the levels of T-tau and/or P-tau affect survival after diagnosis in AD. This observation does not support the theory that these patients have a more advanced disease. However, the individuals with pathological levels of tau had fewer years of education and worse cognitive status indicating a lower cognitive reserve capacity, which might influence life expectancy. These findings might be useful when considering new diagnostic criteria and when interpreting outcomes from future clinical trials of potentially disease-modifying AD therapies.

description: We consider the effective $1+1$-dimensional chiral theory describing fluctuations of the order parameter of the Disoriented Chiral Condensate (DCC) which can be formed in the central rapidity region in a relativistic nucleus-nucleus or nucleon-nucleon collisions at high energy. Using $1+1$-dimensional reduction of QCD at high energies and assuming spin polarization of DDC one can find the Wess-Zumino-Novikov-Witten (WZNW) model at level $k=3$ as the effective chiral theory for the one-dimensional DDC. Some possible phenomenological consequences are briefly discussed.
