description: An analysis of experimental data, obtained at the Linear Accelerator of INR, is carried out with the aim of searching for supernarrow dibaryons in the reactions pd->p+X and pd->p+pX_1. Dibaryons with masses 1904\pm 2, 1926\pm 2, and 1942\pm 2 MeV have been observed in M_{X} missing mass spectra. In M_{X_1} missing mass spectra, the peaks have been found at M_{X_1}=966\pm 2, 986\pm 2, and 1003\pm 2 MeV. These values of M_{X_1} coincide with the ones obtained by a simulation of a decay of the dibaryons into γ+pn. The analysis of the data obtained leads to the conclusion that the observed dibaryons are supernarrow dibaryons, the decay of which into two nucleons is forbidden by the Pauli exclusion principle. A possible interpretation of exited nucleon states with small masses is suggested.

description: The energy dissipation mechanism in blazar jet is unknown. Blazar's flares could provide insights on this problem. Here we report statistical results of XMM-Newton X-ray flares of Mrk 421. We analyze all public XMM-Newton X-ray observations for Mrk 421, and construct the light curves. Through fitting light curves, we obtain the parameters of flare-profiles, such as peak flux ($F_{\rm p}$) and flaring time duration ($T_{\rm fl}$). It is found that both the distributions of $F_{\rm p}$ and $T_{\rm fl}$ obey a power-law form, with the same index of $α_{\rm F}=α_{\rm T}\approx1$. The statistical properties are consistent with the predictions by a self-organized criticality (SOC) system with energy dissipation in one-dimensional space. This is similar to solar flare, but with different space dimensions of the energy dissipation domain. This suggests that X-ray flaers of Mrk 421 are possibly driven by a magnetic reconnection mechanism. Moreover, in the analysis, we find that variability on timescale of $\sim1000\ $s frequently appears. Such rapid variability indicates a magnetic field of $\geq 2.1δ_{\rm D}^{-1/3}$ G ($δ_{\rm D}$ is the Doppler factor) in emission region.

SOME PROBLEMS ON THE ESTIMATION OF UNIMODAL DENSITIES
Creators: name: Fan, Jianqing
name: Bickel, Peter J
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: In this paper, we study, in some new ways, the estimation of unimodal densities. Several methods for estimating unimodal densities are proposed: plug-in MLE, pregrouping techniques, linear spline MLE. Based on the maximum likelihood method, an automatic procedure for estimating a unimodal density as well as its mode is proposed. We also give asymptotic theory for the proposed estimators. An important consequence of this study is that having to estimate the location of a mode does not affect the limiting behavior of the proposed unimodal density estimate. Simulation studies illustrate the proposed methods.
|Delta I|=3/2 Decays of the Omega^- in Chiral Perturbation Theory

description: We study the decays Omega^- -> Cascade+pion using heavy-baryon chiral perturbation theory to quantify the |Delta I|=1/2 rule in these decay modes. The ratio of |Delta I|=3/2 to |Delta I|=1/2 amplitudes is somewhat larger in these decays than it is in other hyperon decays. At leading order there are two operators responsible for the |Delta I|=3/2 parts of the Omega^- decays which also contribute at one loop to other hyperon decays. These one-loop contributions are sufficiently large to indicate (albeit not definitely) that the measured width ratio of Omega^-->Cascade^0+pion^- to Omega^-->Cascade^-+pion^0 = 2.7 may be too large.

description: Wavelet shrinkage methods are widely recognized as a useful tool for non-parametric regression and signal recovery, while Bayesian approaches to choosing the shrinkage method in wavelet smoothing are known to be effective. In this paper we extend the Bayesian methodology to include choice among wavelet bases (and the Fourier basis), and averaging of the regression function estimates over different bases. This results in improved function estimates.

description: Because of license restrictions, it often becomes impossible to strictly reproduce most research results on Twitter data already a few months after the creation of the corpus. This situation worsened gradually as time passes and tweets become inaccessible. This is a critical issue for reproducible and accountable research on social media. We partly solve this challenge by annotating a new Twitter-like corpus from an alternative large social medium with licenses that are compatible with reproducible experiments: Mastodon. We manually annotate both dialogues and sentiments on this corpus, and train a multi-task hierarchical recurrent network on joint sentiment and dialog act recognition. We experimentally demonstrate that transfer learning may be efficiently achieved between both tasks, and further analyze some specific correlations between sentiments and dialogues on social media. Both the annotated corpus and deep network are released with an open-source license.
Information-theoretic interpretation of quantum error-correcting codes

Year: 1997

description: Quantum error-correcting codes are analyzed from an information-theoretic perspective centered on quantum conditional and mutual entropies. This approach parallels the description of classical error correction in Shannon theory, while clarifying the differences between classical and quantum codes. More specifically, it is shown how quantum information theory accounts for the fact that "redundant" information can be distributed over quantum bits even though this does not violate the quantum "no-cloning" theorem. Such a remarkable feature, which has no counterpart for classical codes, is related to the property that the ternary mutual entropy vanishes for a tripartite system in a pure state. This information-theoretic description of quantum coding is used to derive the quantum analogue of the Singleton bound on the number of logical bits that can be preserved by a code of fixed length which can recover a given number of errors.

description: This paper introduces the Generalized Comprehensible Configurable Adaptive Cognitive Structure (G-CCACS), a conceptual vision framework aimed at advancing Trustworthy AI in high-stakes domains (e.g., healthcare, law, policy). G-CCACS is built on the core principles of Operationalized Humility (explicitly managing AI's inherent limitations in causality, context, and knowledge completeness) and Ethical Supremacy (architecturally enforcing normative constraints).Key integrated mechanisms support these principles through a defined processing pipeline (SENSE to OUTCOME layers) under governance oversight: the Graded Causal Validation Pipeline (GCVP) with Causal Fidelity Score (CFS) and Systemic Unfolding & Recomposition Drift (SURD) metrics manages causal uncertainty against context; intrinsic ethical governance via the NormKernel and multi-stage Ethical Escalation Protocol (EEP) enforces norms and handles ambiguity, culminating in a final Foundational Constraint Check (FCC) against verified safety principles before action deployment; an Audit-First design operationalized via detailed EpistemicState objects ensures verifiable traceability and accountability; the Formalization Debt Ratio (FDR) manages epistemic risk from unverified knowledge; and the mandated Formalized Calibration Justification Framework (FCJF) requires auditable, evidence-based validation for all critical configurations.The framework aims to foster demonstrably justifiable, robust, and ethically-aligned performance by structurally integrating its core mechanisms. Architecturally, G-CCACS focuses on internal cognitive and governance integrity, relying on validated external systems and dependency contracts for critical privacy-enhancing technologies and security infrastructure. G-CCACS is presented as a theoretical reference concept requiring significant implementation effort and empirical validation.

description: This paper presents an innovative use of human behavior models for detecting insider threats to information systems. While most work in information security concerns detecting and responding to intruders, violations of system security policy by authorized computer users present a major threat to information security. A promising approach to detection and response is to model behavior of normal users and threats, and apply sophisticated inference methods to detect patterns of behavior that deviate from normal behavior in ways suggesting a possible security threat. This paper presents an approach, based on multi-entity Bayesian networks, to modeling user queries and detecting situations in which users in sensitive positions may be accessing documents outside their assigned areas of responsibility. Such unusual access patterns might be characteristic of users attempting illegal activities such as disclosure of classified information. We present a scalable proof of concept behavior model, provide an experimental demonstration of its ability to detect unusual access patterns in simulated situations, and describe future plans to increase the realism and fidelity of the model.

CONJUGATE PRIORS FOR GENERALIZED LINEAR MODELS
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: We propose a novel class of conjugate priors for the family of generalized linear models. Properties of the priors are investigated in detail and elicitation issues are examined. We establish theorems characterizing the propriety and exis-tence of moments of the priors under various settings, examine asymptotic proper-ties of the priors, and investigate the relationship to normal priors. Our approach is based on the notion of specifying a prior prediction y0 for the response vector of the current study, and a scalar precision parameter a0 which quantifies one's prior belief in y0. Then (y0, a0), along with the covariate matrix X of the current study, are used to specify the conjugate prior for the regression coefficients β in a generalized linear model. We examine properties of the prior for a0 fixed and for a0 random, and study elicitation strategies for (y0, a0) in detail. We also study generalized linear models with an unknown dispersion parameter. An example is given to demonstrate the properties of the prior and the resulting posterior.
Conformal classical Yang-Baxter equation, $S$-equation and $\mathcal{O}$-operators

description: Conformal classical Yang-Baxter equation and $S$-equation naturally appear in the study of Lie conformal bialgebras and left-symmetric conformal bialgebras. In this paper, they are interpreted in terms of a kind of operators, namely, $\mathcal O$-operators in the conformal sense. Explicitly, the skew-symmetric part of a conformal linear map $T$ where $T_0=T_λ\mid_{λ=0}$ is an $\mathcal O$-operator in the conformal sense is a skew-symmetric solution of conformal classical Yang-Baxter equation, whereas the symmetric part is a symmetric solution of conformal $S$-equation. One byproduct is that a finite left-symmetric conformal algebra which is a free $\mathbb{C}[\partial]$-module gives a natural $\mathcal O$-operator and hence there is a construction of solutions of conformal classical Yang-Baxter equation and conformal $S$-equation from the former. Another byproduct is that the non-degenerate solutions of these two equations correspond to 2-cocycles of Lie conformal algebras and left-symmetric conformal algebras respectively. We also give a further study on a special class of $\mathcal{O}$-operators called Rota-Baxter operators on Lie conformal algebras and some explicit examples are presented.

description: Knowledge scouts are software agents that autonomously search for and synthesize user-oriented knowledge (target knowledge) in large local or distributed databases. A knowledge generation metalanguage, KGL, is used to creating scripts defining such knowledge scouts. Knowledge scouts operate in an inductive database, by which we mean a database system in which conventional data and knowledge management operators are integrated with a wide range of data mining and inductive inference operators. Discovered knowledge is represented in two forms: (1) attributional rules, which are rules in attributional calculus -- a logic-based language between propositional and predicate calculus, and (2) association graphs, which graphically and abstractly represent relations expressed by the rules. These graphs can depict multi-argument relationships among different concepts, with a visual indication of the relative strength of each dependency. Presented ideas are illustrated by two simple knowledge scouts, one that seeks relations among lifestyles, environmental conditions, symptoms and diseases in a large medical database, and another that searches for patterns of children's behavior in the National Youth Survey database. The preliminary results indicate a high potential utility of the presented methodology as a tool for deriving knowledge from databases.

description: We study the compatibility of a light bottom squark M_{\tilde b}< O(10 GeV) in the unconstrained MSSM. We consider the one-loop radiative corrections which are large for a heavy gluino (> O(150 GeV)). We then consider the renormalization group flow up to the Grand Unified scale. For most regions of the parameter space with a light sbottom we find colour and charge breaking minima. Only a small window in gluino mass and tan(beta) is consistent with all bounds. This is alleviated by a light gluino, which is however only marginally experimentally allowed.

These contributions are canceled completely in the total gauge-invariant amplitude as it confirmed by one-loop calculations. It explains, in particular, some results of the chiral pertubation theory in the order $p^4$ but this cancelation has no relation to chiral symmetry.

description: Theoretical progress in graphene physics has largely relied on the application of a simple nearest-neighbor tight-binding model capable of predicting many of the electronic properties of this material. However, important features that include electron-hole asymmetry and the detailed electronic bands of basic graphene nanostructures (e.g., nanoribbons with different edge terminations) are beyond the capability of such simple model. Here we show that a similarly simple plane-wave solution for the one-electron states of an atom-based two-dimensional potential landscape, defined by a single fitting parameter (the scattering potential), performs better than the standard tight-binding model, and levels to density-functional theory in correctly reproducing the detailed band structure of a variety of graphene nanostructures. In particular, our approach identifies the three hierarchies of nonmetallic armchair nanoribbons, as well as the doubly-degenerate flat bands of free-standing zigzag nanoribbons with their energy splitting produced by symmetry breaking. The present simple plane-wave approach holds great potential for gaining insight into the electronic states and the electro-optical properties of graphene nanostructures and other two-dimensional materials with intact or gapped Dirac-like dispersions.

description: Three family SU(3)_C x SU(2)_L x U(1)_Y string models in several constructions generically possess two features: (i) an extra local anomalous U(1)_A and (ii) numerous (often fractionally charged) exotic particles beyond those in the minimal supersymmetric model (MSSM). Recently, we demonstrated that the observable sector effective field theory of such a free fermionic string model can reduce to that of the MSSM, with the standard observable gauge group being just SU(3)_C x SU(2)_L x U(1)_Y and the SU(3)_C x SU(2)_L x U(1)_Y-charged spectrum of the observable sector consisting solely of the MSSM spectrum. An example of a model with this property was shown. We continue our investigation of this model by presenting a large set of different flat directions of the same model that all produce the MSSM spectrum. Our results suggest that even after imposing the conditions for the decoupling of exotic states, there may remain sufficient freedom to satisfy the remaining phenomenological constraints imposed by the observed data.

description: The correlation matrix is the key element in optimal portfolio allocation and risk management. In particular, the eigenvectors of the correlation matrix corresponding to large eigenvalues can be used to identify the market mode, sectors and style factors. We investigate how these eigenvalues depend on the time scale of securities returns in the U.S. market. For this purpose, one-minute returns of the largest 533 U.S. stocks are aggregated at different time scales and used to estimate the correlation matrix and its spectral properties. We propose a simple lead-lag factor model to capture and reproduce the observed time-scale dependence of eigenvalues. We reveal the emergence of several dominant eigenvalues as the time scale increases. This important finding evidences that the underlying economic and financial mechanisms determining the correlation structure of securities depend as well on time scales.

Using exact diagonalisation of small clusters, linear spin wave theory and Schwinger boson mean field theory, we show that the transition between the two types of order is first-order, and that it takes place inside the domain where magnetic long-range order is stable with respect to quantum fluctuations.

description: We consider (ν_μ--> ν_e) oscillations in long baseline experiments within a three flavor framework. A non-zero measurement of this oscillation probability implies that the (13) mixing angle `phi' is non-zero. We consider the effect of neutrino propagation through the matter of earth's crust and show that, given the constraints from solar neutrino and CHOOZ data, matter effects enhance the mixing for neutrinos rather than for anti-neutrinos. We need data from two different experiments with different baseline lengths (such as K2K and MINOS) to distinguish matter effects unambiguously.

Zertifizierung von Hochschulbildung

description: Der Bereich der Anerkennung und Zertifizierung von Hochschulbildung wird immer zentraler bei Fragen zur Organisation, Flexibilisierung und Durchlässigkeit des Übergangs zwischen Hochschulbildung und Arbeitsmarkt. Insbesondere im Kontext der Themen 21st century skills sowie Industrie 4.0 stellt sich die Frage, inwiefern neue Formen der Zertifizierung bzw. Ausstellung von Kompetenz-nachweisen notwendig sind. Die HFD Community Working Group Kompetenz-Badges wurde 2018 ins Leben gerufen, um die Chancen und Hindernisse bei der Umsetzung von digitalen Kompetenznachweisen auf Basis von Open Badges auszuloten. Die Arbeit der Gruppe orientierte sich an diesen sechs Leitfragen: 1. Welche Kenntnisse gibt es bereits in potentiellen Nutzerkreisen zu digitalen Kompetenz-nachweisen auf der Basis von Open Badges?
 2. Welche Akzeptanz wird diesem Instrument entgegengebracht und wie wird dessen Nützlichkeit als eine alternative Form der Zertifizierung bzw. Anerkennung eingeschätzt?
 3. Welche Probleme gibt es beim Übergang von der Hochschule in den Arbeitsmarkt?
 4. Können Hochschulen auch den Bedarf an Weiterbildung bei Beschäftigten decken? Welche Rolle hätten sie hier?
 5. Wie schätzen potentielle Nutzer*innen (u. a. Arbeitgeber) die Effektivität von formalen Abschlüssen und den Spielraum für die Berücksichtigung von alternativen oder ergänzenden Zertifikaten bzw. Kompetenzanerkennungsinstrumenten ein?
 6. Welche Rolle könnten Hochschulen bei der Implementierung und der Qualitätssicherung von alternativen oder ergänzenden digitalen Zertifikaten spielen?
 Um sich diesen Fragen konstruktiv und möglichst konkret anzunähern, wurden 2018 insgesamt fünf Gesprächsrunden mit ausgewählten Expert*innen und Stakeholdern im Inland und Ausland durchgeführt. Auf Basis der Ergebnisse wurden drei konkrete Szenarien zum Einsatz von digitalen Kompetenznachweisen auf Basis von Open Badges zur Stärkung von Übergängen von der Hochschulbildung in die Arbeitswelt entwickelt: ein Minimal-Szenario (MinS), ein Medium-Szenario (MedS) und ein Maximal-Szenario (MaxS). In diesem Bericht beschreiben wir die theoretischen Hintergründe (Kapitel 2), das methodische Vorgehen (Kapitel 3), die Zusammenfassung der Ergebnisse entlang der sechs Leitfragen (Kapitel 4), sowie die ausgearbeiteten Szenarien (Kapitel 5). Der Bericht endet mit einer Diskussion und Empfehlungen für weitere Schritte. Abschließend stellen wir eine Liste mit ausgewählten Good-Practice-Beispielen zum Einsatz von digitalen Kompetenznachweisen auf Basis von Open Badges zusammen.

description: This paper introduces G-CCACS (Generalized Comprehensible Configurable Adaptive Cognitive Structure), a novel conceptual reference architecture designed for researchers, policy makers, and practitioners tackling AI safety, ethics, explainability, and governance in high-stakes domains. G-CCACS provides a blueprint for building transparent, auditable, and ethically-grounded AI systems by deeply integrating causal reasoning, normative arbitration, and epistemic traceability.Key mechanisms include the Graded Causal Validation Pipeline (GCVP) with its Causal Fidelity Score (CFS) and Systemic Unfolding & Recomposition Drift (SURD) metric for context-aware validation, alongside an intrinsic ethical governance framework featuring the NormKernel and a multi-stage Ethical Escalation Protocol (EEP). Unlike conventional approaches, G-CCACS embeds ethical enforcement and rigorous causal validation into its core design, operationalizing accountability via an "Audit-First" principle and detailed EpistemicState tracking.This technical specification offers a comprehensive exploration of the G-CCACS layered structure, governance protocols, core metrics, and foundational principles, serving as a reference for advancing trustworthy AI research, policy, and practice.

title: Adolescent Aggression: An Indirect Link between Parenting and Aggression
Creators: name: Shear, Maximillian L.
Publisher: name: George Mason University

Subjects: subject: Bullying
subject: Victimization
subject: Aggression
subject: Parenting
subject: Adolescence

description: Research points to peer victimization as a considerable source of distress during adolescence. Much of the empirical attention placed on peer victimization focuses on risk factors for youth becoming the target of aggression. Included in these risk factors is the manner in which parents interact with their adolescent children. Although the association between parenting and peer victimization is an important one, the nature of the associations between teens’ interactions with their parents and the manner in which they are treated by peers has been largely unaddressed. Using age 15 data of the NICHD SECCYD study, the current study aimed to explore potential mechanisms that mediate the relationship between parenting and peer victimization in adolescence. Specifically, it was hypothesized that adolescents’ aggressive behavior would account for the association between parenting and teens’ experiences with peer victimization. Results indicate that adolescents’ relational aggression mediated the indirect relationship between maternal hostile parenting and higher levels of adolescent self-reports of peer victimization. This mediated effect was particularly strong among boys, for whom relationally aggressive behavior appears to be a particularly notable risk factor for peer victimization. Implications for future research and school and home interventions are discussed.
Asymptotic results for fitting semiparametric transformation models to failure time data from case-cohort studies

description: Semiparametric transformation models are considered for failure time data from case-cohort studies, where the covariates are assembled only for a ran-domly selected subcohort from the entire cohort and additional cases outside the subcohort. We present the estimating procedures for the regression parameters and survival probability. The asymptotic properties of the resulting estimators are developed based on asymptotic results for U-statistics, martingales, stochastic processes and finite population sampling.

Non-Equilibrium Quantum Transport of Chiral Fluids from Kinetic Theory

description: We introduce the quantum-field-theory (QFT) derivation of chiral kinetic theory (CKT) from the Wigner-function approach, which manifests side jumps and non-scalar distribution functions associated with Lorentz covariance and incorporates both background fields and collisions. The formalism is utilized to investigate second-order responses of chiral fluids near local equilibrium. Such non-equilibrium anomalous transport is dissipative and affected by interactions. Contributions from both quantum corrections in anomalous hydrodynamic equations (EOM) of motion and those from the CKT and Wigner functions (WF) are considered in a relaxation-time approximation (RTA). Anomalous charged Hall currents engendered by background electric fields and temperature/chemical-potential gradients are obtained. Furthermore, chiral magnetic/vortical effects (CME/CVE) receive viscous corrections as non-equilibrium modifications stemming from the interplay between side jumps, magnetic-moment coupling, and chiral anomaly.

description: Cloud computing change the Internet into a new computing platform, is a business model that achieve purchase on-demand and pay-per-use in network, has a broad development prospects. Virtualization technology is a core technology of cloud computing, the virtual machine is the basic unit of the cloud computing platforms, cloud providers providing services to clients by virtual machines must ensure the security and isolation. The capability to migrate applications with no perceivable effect to the end user enables service providers to develop new and improved methods for provisioning and maintaining data center infrastructure. Cloud computing providers can now perform hardware maintenance, consolidate CPU and memory resources, or migrate mission-critical applications from a data center when necessary without affecting the service-level agreements (SLAs) of the applications. A cumbersome issue is dealing with the network deployment context required to preserve end-to-end connectivity as VMs are migrated to new physical machines that are likely located on different networks. To the best of our knowledge, all proposed ideas rely on 'virtual networks' (i.e., overlay networks) to facilitate the interconnection of VMs. We take a radically different approach. The significant growth of Internet traffic and increase of routing tables require solutions to address Internet scalability and resiliency. The approach chosen is to move away from the flat legacy Internet routing to hierarchical routing, separating edge networks from transit networks. In the context of Cloud computing and Internet datacenter, Id/locator splitting provides a convenient method for establishing the network context for a VM that is migrated to a new physical machine. A protocol, the Location Identifier Separation Protocol (LISP) follows this paradigm, adding in particular a control-plane based on a mapping system, which separates the location function from the identification function of the IP address. OpenLISP is an open source implementation of the LISP proposal in the FreeBSD OS. OpenLISP provides complete Data Plane support for both encapsulation and decapsulation operations, for IPv4 and IPv6, as well as EID-to-RLOC mapping storage and efficient lookup. As part of the thesis research, control plane implementation of OpenLISP is done. Assuming transit/edge approach is widely deployed in the future Internet; our approach to live migration eliminates the need for non-standard and complex virtual networking schemes to interconnect the VM platforms. Our solution guarantees optimal routing between clients and the VM end-point that moved, regardless of its location. In addition, the solution does not require any change in the DNS infrastructure, which overall reduces operating expenses for the data center administrator.
Strangeness Production Incorporating Chiral Symmetry

description: Chiral symmetry is known to be decisive for an understanding of the low energy sector of strong interactions. It is thus important for a model of relativistic heavy ion collisions to incorporate the dynamical breaking and restoration of chiral symmetry. Thus we study an expansion scenario for a quark-meson plasma using the Nambu--Jona-Lasinio (NJL) model in its three flavor version. The equations of motion for light and strange quarks as well as for pions, kaons and etas are solved using a QMD type algorithm, which is based on a parametrization of the Wigner function. The scattering processes incorporated into this calculation are of the types qq qq, q\bar q q\bar q, q\bar q MM and M q\bar q.

description: Nanosecond laser ablation of p-type Si(111) wafer is presented under an ambient, a water and a glycerin conditions. Effects of pulse energy, number of pulses and type of environment are systematically analyzed with an Optical Profilometer, a Scanning Electron Microscope and an Atomic Force Microscope. Obtained results are compared with Zemax-EE simulations. Self-assembly nano-ripple formation has been observed in an ambient condition. However, these ripples and heat affected zone (HAZ) area disappeared in aqueous medium which enhances the quality of ablation. Moreover, no remarkable oxidation was obtained in ablation zone even in an ambient condition based on the SEM-EDX analysis. Ablation profiles and their depths for different environments are compared with false color technique. Although ablation diameters are comparable each other, their depths are small enough in aqueous medium to control depth profile of damaged area. According to our results, best ablation profiles (precise edges without HAZ) are achieved under an aqueous medium especially in glycerin conditions both in low and high pulse energy regime.
