description: NP-hard problems such as the maximum clique or minimum vertex cover problems, two of Karp's 21 NP-hard problems, have several applications in computational chemistry, biochemistry and computer network security. Adiabatic quantum annealers can search for the optimum value of such NP-hard optimization problems, given the problem can be embedded on their hardware. However, this is often not possible due to certain limitations of the hardware connectivity structure of the annealer. This paper studies a general framework for a decomposition algorithm for NP-hard graph problems aiming to identify an optimal set of vertices. Our generic algorithm allows us to recursively divide an instance until the generated subproblems can be embedded on the quantum annealer hardware and subsequently solved. The framework is applied to the maximum clique and minimum vertex cover problems, and we propose several pruning and reduction techniques to speed up the recursive decomposition. The performance of both algorithms is assessed in a detailed simulation study.

description: The anomalous conducting phase that has been shown to exist in zero field in dilute two-dimensional electron systems in silicon MOSFETs is driven into a strongly insulating state by a magnetic field of about 20 kOe applied parallel to the plane. The data suggest that in the limit of T -> 0 the conducting phase is suppressed by an arbitrarily weak magnetic field. We call attention to striking similarities to magnetic field-induced superconductor-insulator transitions.

description: Finding a robust security mechanism for audit trail logging has long been a poorly satisfied goal. There are many reasons for this. The most significant of these is that the audit trail is a highly sought after goal of attackers to ensure that they do not get caught. Thus they have an incredibly strong incentive to prevent companies from succeeding in this worthy aim. Regulation, such as the European Union General Data Protection Regulation, has brought a strong incentive for companies to achieve success in this area due to the punitive level of fines that can now be levied in the event of a successful breach by an attacker. We seek to resolve this issue through the use of an encrypted audit trail process that saves encrypted records to a true immutable database, which can ensure audit trail records are permanently retained in encrypted form, with no possibility of the records being compromised. This ensures compliance with the General Data Protection Regulation can be achieved.

description: Introduction: Chronic graft-versus-host disease (chronic GVHD) is a leading cause of late death and contributes significantly to morbidity following hematopoietic stem cell transplantation. This study aims to provide a systematic literature review on incidence, mortality, and relapse of chronic GVHD patients. Areas covered: The authors searched for English-language articles published between 2007 and 2017 using PubMed. Studies that applied the 2005 or 2015 NIH Consensus Criteria for the diagnosis and staging of chronic GVHD, and had a cohort size of at least 100 patients were included. Expert opinion: The authors found a wide variation of incidence rates, which can be explained by heterogeneity in the characteristics of study samples and applied transplantation protocols. Chronic GVHD was associated with higher non-relapse mortality (NRM), superior overall survival (OS) and lower risk of relapse. Studies indicated an increased risk for NRM and worse OS in the presence of more severe disease. Future therapies should focus to reach a delicate balance between controlling disease severity among patients diagnosed with chronic GVHD and preserving the graft versus tumor effect which goes along with chronic GVHD and results in improved OS and decreased relapse rate. Nonetheless, factors predicting disease severity still need to be further understood.

description: Under the assumption that the Milky Way's dark halo consists of primordial black hole MACHOs (PBHMACHOs), the mass density of the halo can be measured by the low frequency gravitational waves ($10^{-3} Hz \siml ν_{gw} \siml 10^{-1}$ Hz) from PBHMACHO binaries whose fraction is $\sim 10^{-6}$. We find that ten years observation by LISA will detect $\sim 700$ PBHMACHO binaries and enable us to determine the power index of the density profile within 10% (20%) and the core radius within 25% (50%) in about 90% (99%) confidence level, respectively. The axial ratios of the halo may also be determined within $\sim 10%$. LISA and OMEGA may give us an unique observational method to determine the density profile and the shape of the dark halo to open a new field of observational astronomy.

description: In recent years, Cloud Computing has transformed local businesses and created new business models on the Internet- and Cloud services are still flourishing. But after the emphatic hype in the early years, a more realistic perception of Cloud services has emerged. One reason for this surely is that today, Cloud Computing is considered as an established and well-accepted technology and no longer as a technical novelty. But the second reason for this assessment might also be numerous security issues that Cloud Computing in general or specific Cloud services have experienced since then. In this paper, we revisit attacks on Cloud services and Cloud-related attack vectors that have been published in recent years. We then consider successful or proposed solutions to cope with these challenges. Based on these findings, we apply a security metric in order to rank all these Cloud-related security challenges concerning their severity. This should assist security professionals to prioritize their efforts toward addressing these issues.

description: In this paper, we study the problem of massive connections over limited radio spectrum for the cellular Internet-of-Things (IoT) in the fifth-generation (5G) wireless network. To address the challenging issues associated with channel state information (CSI) acquisition and beam design in the context of massive connections, we propose a new non-orthogonal beamspace multiple access framework. In particular, the user equipments (UEs) are non-orthogonal not only in the temporal-frequency domain, but also in the beam domain. We analyze the performance of the proposed non-orthogonal beamspace multiple access scheme, and derive an upper bound on the weighted sum rate in terms of channel conditions and system parameters. For further improving the performance, we propose three non-orthogonal transmit beam construction algorithms with different beamspace resolutions. Finally, extensive simulation results show that substantial performance gain can be obtained by the proposed non-orthogonal beamspace multiple access scheme over the baseline ones.

Scope of Early Sanskrit Usage : A Wider Approach
Creators: name: Deshpande, Madhav M.
Publisher: name: The University of British Columbia
Year: 2019

description: Sheldon Pollock’s stimulating book Language of The Gods In The World Of Men has offered numerous new ideas on the nature and the place of Sanskrit in ancient India. While I agree with many of his views, I want to offer a different view on the antiquity of the non-ritual Sanskrit usage, and in doing so I will offer a critique of some of Pollock’s ideas. To state it briefly, Pollock advocates a view that Sanskrit usage in Vedic times was pretty much restricted to the domain of ritual, and that only in later or post-Vedic times, and under patronage by certain dynasties, the usage of Sanskrit extended to non-ritual domains and eventually it became a language of the cosmopolis. However, I want to claim that the availability of literature blinds us to a most likely reality of early language use that probably extended more widely beyond the domain of ritual. How does one deduce that conclusion? Towards this aim, I shall offer some methodological solutions. They include the following considerations: 1. Vedic texts present us a ritual, literary and a poetic register. Can such a high register exist in the absence of other registers of usage? 2. One needs to take a close look at Sanskrit vocabulary that is not found in the known Vedic texts, and is recorded by Pāṇini and found in later literature, that has Indo-European cognates. 3. Detecting traces of rare dialects, such as women’s usages, in the Vedic texts. 4. Reviewing Pāṇini’s description of Sanskrit for non-ritual and yet living areas of Sanskrit usage. With such approaches, I shall argue that one can detect the existence of wider domains of the usage of Sanskrit beyond ritual during and after the Vedic period.

description: We develop and calibrate a new method for estimating the gravitational radiation emitted by complex motions of matter sources in the vicinity of black holes. We compute numerically the linearized curvature perturbations induced by matter fields evolving in fixed black hole backgrounds, whose evolution we obtain using the equations of relativistic hydrodynamics. The current implementation of the proposal concerns non-rotating holes and axisymmetric hydrodynamical motions. As first applications we study i) dust shells falling onto the black hole isotropically from finite distance, ii) initially spherical layers of material falling onto a moving black hole, and iii) anisotropic collapse of shells. We focus on the dependence of the total gravitational wave energy emission on the flow parameters, in particular shell thickness, velocity and degree of anisotropy. The gradual excitation of the black hole quasi-normal mode frequency by sufficiently compact shells is demonstrated and discussed. A new prescription for generating physically reasonable initial data is discussed, along with a range of technical issues relevant to numerical relativity.

description: $\nabla$-algebra is a natural generalization of Heyting algebra, unifying many algebraic structures including bounded lattices, Heyting algebras, temporal Heyting algebras and the algebraic presentation of the dynamic topological systems. In a series of two papers, we will systematically study the algebro-topological properties of different varieties of $\nabla$-algebras. In the present paper, we start with investigating the structure of these varieties by characterizing their subdirectly irreducible and simple elements. Then, we prove the closure of these varieties under the Dedekind-MacNeille completion and provide the canonical construction and the Kripke representation for $\nabla$-algebras by which we establish the amalgamation property for some varieties of $\nabla$-algebras. In the sequel of the present paper, we will complete the study by covering the logics of these varieties and their corresponding Priestley-Esakia and spectral duality theories.

description: While classification of arbitrary structures in high dimensions may require complete quantitative information, for simple geometrical structures, low-dimensional qualitative information about the boundaries defining the structures can suffice. Rather than using dense, multi-dimensional data, we propose a deep neural network (DNN) classification framework that utilizes a minimal collection of one-dimensional representations, called \emph{rays}, to construct the "fingerprint" of the structure(s) based on substantially reduced information. We empirically study this framework using a synthetic dataset of double and triple quantum dot devices and apply it to the classification problem of identifying the device state. We show that the performance of the ray-based classifier is already on par with traditional 2D images for low dimensional systems, while significantly cutting down the data acquisition cost.

Deviations from unitarity are characterized by rank $M\le N$ and a set of eigenvalues $0>M,n$ the correlation functions acquire the universal form found earlier for weakly non-Hermitian random matrices.

Philander opossum

description: Philander opossum (Linnaeus, 1758)
TYPE MATERIAL AND TYPE LOCALITY: RMNH 25421a, the lectotype (designated by Hershkovitz, 1976), is a fluid-preserved adult female with pouch young collected in Surinam.
 SYNONYMS: frenatus Olfers, 1818; superciliaris Olfers, 1818.
 DISTRIBUTION: As currently recognized (see Remarks), Philander opossum occurs in eastern Amazonia, including the Guianas and northern Brazil; in Brazil, this species occurs in Amapá, Amazonas (north of the Amazon and east of the Rio Negro), Pará, and Roraima. No published range map accurately shows the range of this species as restricted by recent revisionary research.
 REMARKS: Patton and da Silva’s (2008) concept of Philander opossum included several taxa herein recognized as distinct species, including P. canus, P. melanurus, and P. vossi (formerly P. pallidus; see below). In fact, none of these taxa are closely related to P. opossum, which appears, instead, to belong to a monophyletic group that includes P. andersoni and P. mcilhennyi (see Voss et al., 2018). The identity of frenatus as a subjective synonym of P. opossum was discussed by Voss and Angermann (2018; in Voss et al., 2018). The identity of superciliaris as a subjective synonym was fixed by neotype selection (Voss et al., 2018).

description: In this paper we present novel $ADE$ correspondences by combining an earlier induction theorem of ours with one of Arnold's observations concerning Trinities, and the McKay correspondence. We first extend Arnold's indirect link between the Trinity of symmetries of the Platonic solids $(A_3, B_3, H_3)$ and the Trinity of exceptional 4D root systems $(D_4, F_4, H_4)$ to an explicit Clifford algebraic construction linking the two ADE sets of root systems $(I_2(n), A_1\times I_2(n), A_3, B_3, H_3)$ and $(I_2(n), I_2(n)\times I_2(n), D_4, F_4, H_4)$. The latter are connected through the McKay correspondence with the ADE Lie algebras $(A_n, D_n, E_6, E_7, E_8)$. We show that there are also novel indirect as well as direct connections between these ADE root systems and the new ADE set of root systems $(I_2(n), A_1\times I_2(n), A_3, B_3, H_3)$, resulting in a web of three-way ADE correspondences between three ADE sets of root systems.

description: This article explores a novel interdisciplinary approach to the philosophy of history by integrating concepts from dimensional theory and topology. Challenging the traditional linear view of historical chronology, the author proposes a multidimensional model where historical events are situated within a volumetric field of interactions. Using topological analysis, the study reconceptualizes causality, continuity, and historical memory, offering a dynamic framework for understanding the complexity of historical processes. The paper invites historians, philosophers, and complexity theorists to consider history not as a fixed narrative, but as a living structure shaped by relational forces and observational perspective.м

Furthermore the reflections propose some research questions which should be answered to understand fully which factors drive the spatial spread of COVID-19. For example why was so France so much suffering from COVID-19 with a high over mortality, and why Germany after all seems to get of cheaply from COVID-19 in spring 2020?

description: We develop a novel data-driven approach to the inverse problem of classical statistical mechanics: given experimental data on the collective motion of a classical many-body system, how does one characterise the free energy landscape of that system? By combining non-parametric Bayesian inference with physically-motivated constraints, we develop an efficient learning algorithm which automates the construction of approximate free energy functionals. In contrast to optimisation-based machine learning approaches, which seek to minimise a cost function, the central idea of the proposed Bayesian inference is to propagate a set of prior assumptions through the model, derived from physical principles. The experimental data is used to probabilistically weigh the possible model predictions. This naturally leads to humanly interpretable algorithms with full uncertainty quantification of predictions. In our case, the output of the learning algorithm is a probability distribution over a family of free energy functionals, consistent with the observed particle data. We find that surprisingly small data samples contain sufficient information for inferring highly accurate analytic expressions of the underlying free energy functionals, making our algorithm highly data efficient. We consider excluded volume particle interactions, which are ubiquitous in nature, whilst being highly challenging for modelling in terms of free energy. To validate our approach we consider the paradigmatic case of one-dimensional fluid and develop inference algorithms for the canonical and grand-canonical statistical-mechanical ensembles. Extensions to higher-dimensional systems are conceptually straightforward, whilst standard coarse-graining techniques allow one to easily incorporate attractive interactions.

description: Optimization of mutual synchronization between a pair of limit-cycle oscillators with weak symmetric coupling is considered in the framework of the phase reduction theory. By generalizing a previous study on the optimization of cross-diffusion coupling matrices between the oscillators, we consider optimization of mutual coupling signals to maximize the linear stability of the synchronized state, which are functionals of the past time sequences of the oscillator states. For the case of linear coupling, optimization of the delay time and linear filitering of coupling signals are considered. For the case of nonlinear coupling, general drive-response coupling is considered, and the optimal response and driving functions are derived. The theoretical results are exemplified by numerical simulations.

description: We consider the geometrical aspects of the Krichever map in the context of Jacobian Super KP hierarchy. We use the representation of the hierarchy based on the Faa` di bruno recursion relations, considered as the cocycle condition for the natural double complex associated with the deformations of super Krichever data. Our approach is based on the construction of the universal super divisor (of degree g), and a local universal family of geometric data which give the map into the Super Grassmannian.

description: Inelastic neutron scattering has been used to obtain a comprehensive description of the absolute dynamical spin susceptibility $χ'' (q,ω)$ of the underdoped superconducting cuprate YBa_2 Cu_3 O_{6.5} ($T_c = 52 K$) over a wide range of energies and temperatures ($2 meV \leq \hbar ω\leq 120 meV$ and $5K \leq T \leq 200K$). Spin excitations of two different symmetries (even and odd under exchange of two adjacent CuO_2 layers) are observed which, surprisingly, are characterized by different temperature dependences. The excitations show dispersive behavior at high energies.

description: The exploration of the universe is experiencing a huge development thanks to the success and possibilities of today's major space telescope missions which can generate measurements and images with a resolution 100 times higher than their precedents. This big ecosystem of observations, aimed at expanding the limits of known science, can be analyzed using personal computers thanks to the implementation of interoperable Virtual Observatory (VO) technologies and massive portals of stellar catalogs and databases. In this context of global analysis of astronomical big data, sonification has the potential of adding a complementary dimension to visualization, enhancing the accessibility of the archives, and offering an alternative strategy to be used when overlapping issues and masking effects are found in purely graphical representations. This article presents a collection of sonification and musification prototypes that explore the case studies of the MILES and STELIB stellar libraries from the Spanish Virtual Observatory (SVO), and the Kepler Objects of Interest light curve database from the Space Telescope Science Institute archive (STScI). The work makes use of automation, machine learning, and deep learning algorithms to offer a palette of resources that could be used in future developments oriented towards an auditory virtual observatory proposal. It includes a user study that provides qualitative and quantitative feedback from specialized and non-specialized users in the fields of Music and Astronomy.

description: Habitat restoration offers a unique opportunity to recover biodiversity and study ecological processes in new habitats, such as successional changes in communities. In new habitats, an increase in species richness over time and a decrease in beta-diversity between consecutive samplings are expected, and several ecological mechanisms can drive these temporal variations. An approach using functional traits can reveal how communities are assembled through time. Therefore, we aimed to assess temporal patterns in both taxonomic and functional (trait-based) composition and diversity of zooplankton in a newly created permanent pond, exploring the succession patterns and the underlying ecological mechanisms over four hydrological years. For this, zooplankton samples were bimonthly taken over the first four years after an interdunal pond was created. We estimated a set of taxonomic and functional indices, including Hill numbers, functional richness, dispersion, specialization and redundancy, and taxonomic and functional beta diversity. Their trends over time were analyzed, as well as the relationship with environmental variables and the correlation among them. The results showed an increasing trend in taxonomic diversity along the four-year succession. Regarding beta diversity between samplings, a decreasing trend was observed for taxonomic and functional values. Measured local environmental conditions played a minor role driving variations in both community and traits assembly, but the role of unmeasured variables, biotic interactions and regional processes cannot be discarded. Functional indices provided complementary information to the taxonomic ones: the positive correlation between taxonomic and functional richness indicates that arriving species are adding novel combinations of traits to the communities.

description: Motivated by the ``universe as a brane'' idea, we investigate the motion of a $(D-2)$-brane (or domain wall) that couples to bulk matter. Usually one would expect the spacetime outside such a wall to be time dependent however we show that in certain cases it can be static, with consistency of the Israel equations yielding relationships between the bulk metric and matter that can be used as ansätze to solve the Einstein equations. As a concrete model we study a domain wall coupled to a bulk dilaton with Liouville potentials for the dilaton both in the bulk and on the wall. The bulk solutions we find are all singular but some have black hole or cosmological horizons, beyond which our solutions describe domain walls moving in time dependent bulks. A significant period of world volume inflation occurs if the potential on the wall is not too steep; in some cases the bulk also inflates (with the wall comoving) while in others the wall moves relative to a non-inflating bulk. We apply our method to obtain cosmological solutions of Hořava-Witten theory compactified on a Calabi-Yau space. tive to a non-inflating bulk.

David Gale's subset take-away game

Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: Subset take-away is a two-player game involving a fixed finite set A. Players alternate choosing a proper, non-empty subset of A, with the condition that one may not name a set containing a set that was named earlier. A player unable to move loses. It was conjectured by David Gale that this game is always a second player win, and this was known to hold if A has no more than 5 elements. In this paper, we describe a technique called "binary star reduction" that often allows one to dramatically reduce the complexity of a position. Using this tool and some computer search we show that Gale's conjecture holds when A has six elements. We also show how this game can be interpreted geometrically.

description: Philander pebas Voss et al., 2018
TYPE MATERIAL AND TYPE LOCALITY: MVZ 190343, the holotype by original designation, consists of the skin, skull, and frozen tissues of an adult male collected at Igarapé Nova Empresa (6.80° S, 70.73° W) on the left bank of the Rio Juruá, Amazonas, Brazil.
SYNONYMS: None.
 DISTRIBUTION: As currently documented by examined specimens, Philander pebas occurs in eastern Ecuador (Orellana), eastern Peru (Loreto, Madre de Dios, Ucayali), and western Brazil (Acre, Amazonas), but Voss et al. (2018) speculated that the species might range throughout the várzea landscapes (seasonally inundated by white-water rivers) of western Amazonia, including those in southeastern Colombia, where it is still unknown.
REMARKS: A morphological description, illustrations, comparisons with congeneric species, summary statistics for external and craniodental measurements, and analyses of mtDNA sequence data were provided by Voss et al. (2018).

Quantum field and uniformly accelerated oscillator

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We present an exact treatment of the influences on a quantum scalar field in its Minkowski vacuum state induced by coupling of the field to a uniformly accelerated harmonic oscillator. We show that there are no radiation from the oscillator in the point of view of a uniformly accelerating observer. On the other hand, there are radiations in the point of view of an inertial observer. It is shown that Einstein-Podolsky-Rosen (EPR) like correlations of Rindler particles in Minkowski vacuum states are modified by a phase factor in front of the momentum-symmetric Rindler operators. The exact quantization of a time-dependent oscillator coupled to a massless scalar field was given.

title: Western Tigray: The Unresolved Challenge and a Test for Ethiopia
Creators: name: Gebrehiwot Berhe, Mulugeta

Subjects: subject: Ethiopia

description: Contests over administrative boundaries and identity-based demands have become a major source of conflict in contemporary Ethiopia, with virtually no regional state unaffected. This paper examines the case of Western Tigray to explore the nature of these disputes, concluding that they are symptoms of a broader national political crisis rather than isolated issues. Ethiopia’s multinational federation, while recognising national identities, risks fuelling reactionary and exclusionary nationalism, exacerbated by rent-seeking political elites. The study argues that constitutional mechanisms, including referenda, cannot resolve these deep-rooted problems. Instead, it proposes an incremental, transformative three-stage process: securing a temporary political settlement and nationwide cessation of hostilities; restoring the constitutional status quo as a foundation for credible, inclusive dialogue; and conducting multi-level national dialogues to address fundamental political challenges. Only through such a comprehensive and collaborative approach can sustainable peace be achieved.
Velocity and density profiles of granular flow in channels using lattice gas automaton

description: We have performed two-dimensional lattice-gas-automaton simulations of granular flow between two parallel planes. We find that the velocity profiles have non-parabolic distributions while simultaneously the density profiles are non-uniform. Under non-slip boundary conditions, deviation of velocity profiles from the parabolic form of newtonian fluids is found to be characterized solely by ratio of maximal velocity at the center to the average velocity, though the ratio depends on the model parameters in a complex manner. We also find that the maximal velocity ($u_{max}$) at the center is a linear function of the driving force (g) as $u_{max} = αg - δ$ with non-zero $δ$ in contrast with newtonian fluids. Regarding density profiles, we observe that densities near the boundaries are higher than those in the center. The width of higher densities (above the average density) relative to the channel width is a decreasing function of a variable which scales with the driving force (g), energy dissipation parameter ($ε$) and the width of the system (L) as $g^μ L^ν/ε$ with exponents $μ= 1.4 \pm 0.1$ and $ν= 0.5 \pm 0.1$. A phenomenological theory based on a scaling argument is presented to interpret these findings.
