Relativistic bias in neutrino cosmologies

description: Halos and galaxies are tracers of the underlying dark matter structures. While their bias is well understood in the case of a simple Universe composed dominantly of dark matter, the relation becomes more complex in the presence of massive neutrinos. Indeed massive neutrinos introduce rich dynamics in the process of structure formation leading to scale-dependent bias. We study this process from the perspective of general relativity employing a simple spherical collapse model. We find a characteristic signature at the neutrino free-streaming scale in addition to a large-scale feature from general relativity. The scale-dependent halo bias opposes the suppression in the matter distribution due to neutrino free-streaming and leads to corrections of a few percent in the halo power spectrum. It is not only sensitive to the sum of the neutrino-masses, but respond to the individual masses. Accurate models for the neutrino bias are a crucial ingredient for the future data analysis and play an important role in constraining the neutrino masses.

description: Imbalance in production and clearance of amyloid beta (Aβ) is the primary reason for its deposition in Alzheimer disease. Macroautophagy/autophagy is one of the important mechanisms for clearance of both intracellular and extracellular Aβ. Here, through screening, we identified alborixin, an ionophore, as a potent inducer of autophagy. We found that autophagy induced by alborixin substantially cleared Aβ in microglia and primary neuronal cells. Induction of autophagy was accompanied by up regulation of autophagy proteins BECN1/Beclin 1, ATG5, ATG7 and increased lysosomal activities. Autophagy induced by alborixin was associated with inhibition of the phosphoinositide 3-kinase (PI3K)-AKT pathway. A knock down of PTEN and consistent, constitutive activation of AKT inhibited alborixin-induced autophagy and consequent clearance of Aβ. Furthermore, clearance of Aβ by alborixin led to significant reduction of Aβ-mediated cytotoxicity in primary neurons and differentiated N2a cells. Thus, our findings put forward alborixin as a potential anti-Alzheimer therapeutic lead.
Generating Adaptive and Robust Filter Sets Using an Unsupervised Learning Framework

description: In this paper, we introduce an adaptive unsupervised learning framework, which utilizes natural images to train filter sets. The applicability of these filter sets is demonstrated by evaluating their performance in two contrasting applications - image quality assessment and texture retrieval. While assessing image quality, the filters need to capture perceptual differences based on dissimilarities between a reference image and its distorted version. In texture retrieval, the filters need to assess similarity between texture images to retrieve closest matching textures. Based on experiments, we show that the filter responses span a set in which a monotonicity-based metric can measure both the perceptual dissimilarity of natural images and the similarity of texture images. In addition, we corrupt the images in the test set and demonstrate that the proposed method leads to robust and reliable retrieval performance compared to existing methods.

 Comments. This species was originally described under Forrestopius. However, it shows many features that disagree with the generic diagnosis, such as the palpal formula 4:3 (vs. 5: 4 in Forrestopius); similar palpal formula can be also found in Leurus xalifer Gauld & Sithole, 2002. Leurus larryi has the protibial spur antero-dorsally with comb and postero-dorsally with velum (vs. protibial spur antero-dorsally without comb and without velum and postero-dorsally with comb in Forrestopius). Additionally, the Forrestopius species that have two mandibular teeth have 14–20 flagellomeres and the species with three teeth have between 26–30 flagellomeres, while L. larryi has two mandibular teeth and 30–32 flagellomeres.

description: Both optical wireless communications (OWC) and Terahertz (THz) communication systems are regarded as enablers for the 6th-generation (6G) networks. Facing the 6G requirements of ultra-dense and high-rate networks, vertical-cavity surface-emitting laser (VCSEL)-based OWC is considered as a strong contender for providing high data rates with ultra-small cells. Hence, this work quantitatively compares VCSEL-based OWC and THz communication in terms of energy efficiency. We derive the energy efficiency model for realistic systems by including non-linearity power conversion of VCSEL and area-bandwidth tradeoff of the photodiode (PD) for OWC, and gain and power loss in cascaded THz systems, respectively. Then, we formulate the similarity of embedding optical lenses into VCSEL-based system and high-directivity antenna into THz system to achieve high channel gain, i.e., leading to a gain-coverage tradeoff for both systems. Taking account of this performance tradeoff in analyzing two systems' energy efficiency, we show numerically the superiority of the VCSEL-based system, while the THz system is more robust in long-range scenarios due to a more relaxed relationship between pointing error and transmission distances. This study provides design guidelines for selecting appropriate technologies tailored to various 6G application scenarios from an energy efficiency perspective.

Digitale Teilhabe durch Stärkung von digitalen Kompetenzen: Ansätze für die Soziokulturelle Animation im Kontext der Quartierarbeit
Creators: name: Köppel, Amrei
Publisher: name: Hochschule Luzern – Soziale Arbeit
Year: 2024

description: In der vorliegenden Literaturarbeit von Amrei Köppel mit dem Titel «Digitale Teilhabe durch Stärkung von digitalen Kompetenzen - Ansätze für die Soziokulturelle Animation im Kontext der Quartierarbeit» wird untersucht, wie digitale Teilhabe durch die Vermittlung von digitalen Kompetenzen im Arbeitsfeld der Quartierarbeit gestärkt werden kann und welche Folgerungen sich daraus für die soziokulturelle Praxis ergeben. Es zeigt sich, dass Teilhabe digitalen (Grund-)Kompetenzen voraussetzt und Teilhabechancen nicht für alle Menschen gleich verteilt sind. In der Schweiz existiert deshalb ein gesetzlicher Auftrag, um Grundkompetenzen zu stärken. Dieser führte zur Entstehung von nonformalen Bildungsangeboten wie dem Projekt «Lernstube». Die Autorin hat die Haltung und Arbeitsweise der Lernstube aus soziokultureller Perspektive untersucht und festgestellt, dass das Projekt viele Parallelen zu den soziokulturellen Arbeitsprinzipen aufweist. Jedoch besteht noch Verbesserungspotenzial bei den Partizipationsmöglichkeiten. Die daraus resultierenden Erkenntnisse wurden genutzt, um Handlungsmöglichkeiten für die Quartierarbeit vorzuschlagen. Diese bestehen in den Bereichen der offenen Zielgruppendefinierung, der Kooperation und Netzwerkstärkung, der Nutzung von bestehenden Strukturen und Angeboten sowie der Schaffung neuer Angebote. Für die soziokulturelle Profession konnte geschlussfolgert werden, dass die Vermittlung von digitalen Kompetenzen als Handlungsfeld vermehrt in den Fokus genommen werden muss und digitalen Kompetenzen innerhalb der Profession selbst, gestärkt werden sollten.

Transport properties of the hierarchical model for stretched polymers

description: We prove that the hierarchical fractal model recently proposed for describing the stretched polymers [A. N. Samukhin et al, Phys. Rev. Lett.{\bf 78}, 326(1997)] is equivalent to a one-dimensional chain with hierarchical aperiodic structure. By use of the transfer matrix technique we calculate the electronic transmission and the dc conductance. We find that there exist sharp-edged transmission subbands and gaps, but the transmission subbands are rich in substructures which show self-similarity. The temperature dependence of conductance $g (T)$ is sensitive to the variation of the Fermi level and to the structure parameters $m$ and $n$ of the original fractal structure. The relationship of the obtained results to the experimental data and other theoretical works is discussed.

Dust evolution in the circumstellar disc of the unclassified B[e] star HD 50138

description: We studied the disc of the unclassified B[e] star HD 50138, in order to explore its structure, and to find indications for the evolutionary status of this system, whether it is a young Herbig Be or a post-main-sequence star. Using high spatial resolution interferometric measurements from MIDI instrument (N-band) on the Very Large Telescope Interferometer, we analysed the disc size, the time-variability of the disc's thermal emission, and the spectral shape of the $10~μ$m silicate feature. By fitting simple disc models, we determined the inclination and the mid-infrared size of the disc, confirming earlier results based on a lower number of observations. We searched for mid-infrared temporal variability of different regions of the disc, and concluded that its morphology is not experiencing significant changes over the observed epochs. We characterized the mid-infrared silicate feature by determining the feature amplitude and the $11.3/9.8~μ$m flux ratio. The latter parameter is a good indicator of the grain size. The shape of the feature suggests the presence of crystalline silicate grains in the disc. The interferometric data revealed a strong radial trend in the mineralogy: while the disc's innermost region seems to be dominated by forsterite grains, at intermediate radii both forsterite and enstatite may be present. The outer disc may predominantly contain amorphous silicate particles. A comparison of the observed spectral shape with that of a sample of intermediate-mass stars (supergiants, Herbig Ae/Be stars, unclassified B[e] stars) implied that the evolutionary state of HD 50138 cannot be unambiguously decided from mid-IR spectroscopy.

CYBERSECURITY THREATS, VULNERABILITIES AND ATTACKS: A COMPREHENSIVE APPROACH
Creators: name: Samarov, Xusnutdin

Publisher: name: Zenodo
Year: 2025

description: As the digital environment has become increasingly influential in our lives, crimes are also increasingly using the digital environment. Technologies such as social networks, cryptocurrencies, and cloud computing, which are important components of the digital environment, are surrounded by a number of security problems. Over the past few years, cybercriminals have automated attacks, making them a regular job for themselves, and providing a number of services. The use of traditional security systems such as next-generation firewalls, antivirus/antimalware programs, IDS/IPS systems, and access control is no longer enough to reduce the attack load. It is worth noting that today, the development of new innovative solutions to prevent cyberattacks is becoming a pressing issue. This article studies and analyzes cybersecurity problems. In this analysis, the terms threat, vulnerability, and attack are defined as cybersecurity security problems, and their types are presented. This article proposes several solutions for detecting cyberattacks, from which the use of machine learning methods, deep learning, is proposed as an effective solution to prevent a number of possible future attacks. However, it should be noted that these methods are not resistant to evasion and circumvention of cyberattacks.

description: This is a review of rare and forbidden decays of the $τ$ lepton. For the rare decays, this includes new results on the chiral anomaly decay $\taupietapio$, new upper limits on the second-class-current decay $\taupieta$, and the observations of the Cabibbo-suppressed decay $\tauketa$ and the internal conversion decay $\taueee$. For the forbidden decays, there are new upper limits on the radiative decays $\tauegamma$ and $\taumugamma$. Some forbidden decays which have not been previously searched for are also suggested.
Solvation effects on kinetics of methylene chloride reactions in sub- and supercritical water: theory, experiment, and ab initio calculations

description: The nature of the CH2Cl2 neutral/acidic hydrolysis reaction from ambient to supercritical conditions (25 C to 600 C at 246 bar) is explored. Of primary interest is the effect of the changing dielectric behavior of the water solvent over this temperature range on this reaction. Experiments reveal that significant CH2Cl2 hydrolysis occurs under subcritical temperatures, while relatively little hydrolysis occurs under supercritical conditions. These trends cannot be explain by simple Arrhenius behavior. A combination of Kirkwood theory and ab initio modeling provides a means of successfully accounting for this behavior both qualitatively and quantitatively. The results show that increases in the activation energy and a changing reaction profile with a decreasing dielectric constant provide a mechanism for a slowing of the reaction at higher temperatures by as much as three orders of magnitude. These solvent effects are captured quantitatively in a correction factor to the Arrenius form of the rate constant, which is incorporated into a global rate expression proposed for CH2Cl2 hydrolysis that provides good predictions of the experimental data.

description: Combining equilibrium and non-equilibrium molecular dynamics simulations with accurate carbon potentials, we determine the thermal conductivity $λ$ of carbon nanotubes and its dependence on temperature. Our results suggest an unusually high value $λ{\approx}6,600$~W/m$\cdot$K for an isolated (10,10) nanotube at room temperature, comparable to the thermal conductivity of a hypothetical isolated graphene monolayer or diamond. Our results suggest that these high values of $λ$ are associated with the large phonon mean free paths in these systems; substantially lower values are predicted and observed for the basal plane of bulk graphite.

Enhanced ponderomotive force in graphene due to interband resonance

Year: 2019
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We analyze intrinsic nonlinearities in two-dimensional polaritonic materials interacting with an optical wave. Focusing on the case of graphene, we show that the second-order nonlinear optical conductivity due to carrier density fluctuations associated with the excitation of a plasmon polariton is closely related to the ponderomotive force due to the oscillating optical field. This relation is first established through an elegant thermodynamic approach for a Drude-like plasma, in the frequency range where intraband scattering is the dominant contribution to conductivity. Subsequently, we extend our analysis to the interband regime, and show that for energies approximately half the Fermi energy, the intraband contribution to the ponderomotive force diverges. In practice, thermal broadening regularizes this divergence as one would expect, but even at room temperature typically leaves a strong ponderomotive enhancement. Finally, we study the impact of nonlocal corrections and find that nonlocality does not lead to further broadening (as one would expect in the case of Landau damping), but rather to a splitting of the ponderomotive interband resonance. Our analysis should prove useful to the open quest for exploiting nonlinearities in graphene and other two-dimensional polaritonic materials, through effects such as second harmonic generation and photon drag.

Maximal Stability Regions for Superconducting Ground States of Generalized Hubbard Models

description: For a class of generalized Hubbard models, we determine the maximal stability region for the superconducting eta-pairing ground state. We exploit the Optimized Ground State (OGS) approach and the Lanczos diagonalization procedure to derive a sequence of improved bounds. We show that some pieces of the stability boundary are asymptotic, namely independent on the OGS cluster size. In this way, necessary and sufficient conditions are obtained to realize superconductivity in terms of an eta-pairing ground state. The phenomenon is explained by studying the properties of certain exact eigenstates of the OGS hamiltonians.

Solar cycle variation in meteor rates
Creators: name: Campbell-Brown, Margaret D.
Publisher: name: arXiv
Year: 2019
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Sixteen years of meteor radar data from the Canadian Meteor Orbit Radar (CMOR) were used to investigate the link between observed meteor rates and both solar and geomagnetic activity. Meteor rates were corrected for transmitter power and receiver noise, and seasonal effects were removed. A strong negative correlation is seen between solar activity, as measured with the 10.7 cm flux, and observed meteor rates. This lends support to the idea that heating in the atmosphere at times of elevated solar activity changes the scale height and therefore the length and maximum brightness of meteors; a larger scale height near solar maximum leads to longer, fainter meteors and therefore lower rates. A weaker negative correlation was observed with geomagnetic activity as measured with the $K$ index; this correlation was still present when solar activity effects were removed. Meteor activity at solar maximum is as much as 30\% lower than at solar minimum, strictly due to observing biases; geomagnetic activity usually affects meteor rates by less than 10 percent.

description: In verschiedenen Systemen zeigen sich heutzutage herausfordernde Verhaltensweisen mit erheblichen Auswirkungen, insbesondere an Schulen. Der Umgang damit ist anspruchsvoll und erfordert nicht nur ein tieferes Verständnis der Ursachen, sondern auch innovative Ansätze, um einer Überforderung der Fachpersonen entgegenzuwirken. Gleichzeitig sollen Stigmatisierung und Exklusion der betroffenen Kinder vermieden werden, um ihre erfolgreiche Integration sicherzustellen.

Diese qualitative Forschungsarbeit konzentriert sich auf die Untersuchung eines Praxisinstrumentes in Form eines Bilderbuches mit dem Titel Immer wieder Ron. Ziel der Arbeit ist dessen Optimierung, um einen konstruktiven Umgang mit herausfordernden Verhaltensweisen im Schulzimmer zu ermöglichen.

Für die Ausarbeitung der Optimierungsvorschläge für das Praxisinstrument wurden neben der Auseinandersetzung mit Entstehungs- und Erklärungstheorien auch die Perspektiven und Erfahrungen der betroffenen Fachpersonen und Kindern anhand von Gruppendiskussionen ermittelt. Die Auswertung der Diskussionen erfolgte mittels des sechsstufigen Auswertungsverfahrens nach Mühlfeld et al.

Die Ergebnisse zeigen, dass das Praxisinstrument relevant und geeignet ist, jedoch Optimierungen in Bezug auf die inhaltliche Relevanz, die Praxistauglichkeit sowie der Sensibilisierung der Thematik im Allgemeinen erforderlich sind. Konkrete Umsetzungspunkte für die Optimierungen wurden identifiziert. Nicht zuletzt wird durch die Arbeit deutlich, dass die interdisziplinäre Zusammenarbeit zwischen Schulen und der Sozialen Arbeit von grosser Bedeutung ist und als vielversprechende Möglichkeit für künftige Entwicklungen betrachtet werden soll.

description: Many controversies in statistics are due primarily or solely to poor quality control in journals, bad statistical textbooks, bad teaching, unclear writing, and lack of knowledge of the historical literature. One way to improve the practice of statistics and resolve these issues is to do what initiators of the 2016 ASA statement did: take one issue at a time, have extensive discussions about the issue among statisticians of diverse backgrounds and perspectives and eventually develop and publish a broadly supported consensus on that issue. Upon completion of this task, we then move on to deal with another core issue in the same way. We propose as the next project a process that might lead quickly to a strong consensus that the term “statistically significant” and all its cognates and symbolic adjuncts be disallowed in the scientific literature except where focus is on the history of statistics and its philosophies and methodologies. Calculation and presentation of accurate p-values will often remain highly desirable though not obligatory. Supplementary materials for this article are available online in the form of an appendix listing the names and institutions of 48 other statisticians and scientists who endorse the principal propositions put forward here.

description: I will review the current status of exotic hadrons in the meson sector. There is currently strong evidence that a scalar glueball mixed into the normal scalar mesons has been found. There is also an interesting candidate for the tensor glueball state. Finally, I will discuss hybrid mesons with explicitly exotic quantum numbers.

description: We study the spin transport theoretically in heterostructures consisting of a ferromagnetic metallic thin film sandwiched between heavy-metal and oxide layers. The spin current in the heavy metal layer is generated via the spin Hall effect, while the oxide layer induces at the interface with the ferromagnetic layer a spin-orbital coupling of the Rashba type. Impact of the spin Hall effect and Rashba spin-orbit coupling on the spin Seebeck current is explored with a particular emphasis on nonlinear effects. Technically, we employ the Fokker-Planck approach and contrast the analytical expressions with full numerical micromagnetic simulations. We show that when an external magnetic field is aligned parallel (antiparallel) to the Rashba field, the spin-orbit coupling enhances (reduces) the spin pumping current. In turn, the spin Hall effect and the Dzyaloshinskii-Moriya interaction are shown to increase the spin pumping current.

description: The zero temperature effective equation of motion is derived for a scalar field interacting with other fields. For a broad range of cases, involving interaction with as few as one or two fields, dissipative regimes are found for the scalar field system. The zero temperature limit constitutes a baseline effect that will be prevalent in any general statistical state. Thus, the results found here provide strong evidence that dissipation is the norm not exception for an interacting scalar field system. For application to inflationary cosmology, this provides convincing evidence that warm inflation could be a natural dynamics once proper treatment of interactions is done. The results found here also may have applicability to entropy production during the chiral phase transition in heavy ion collision.

description: The interband polarizations induced by two phase-locked pulses in a semiconductor show strong interference effects depending on the time tau_1 separating the pulses. The four-wave mixing signal diffracted from a third pulse delayed by tau is coherently controlled by tuning tau_1. The four-wave mixing response is evaluated exactly for a two-level system coupled to a single LO phonon. In the weak coupling regime it shows oscillations with the phonon frequency which turn into sharp peaks at multiples of the phonon period for a larger coupling strength. Destructive interferences between the two phase-locked pulses produce a splitting of the phonon peaks into a doublet. For fixed tau but varying tau_1 the signal shows rapid oscillations at the interband-transition frequency, whose amplitude exhibits bursts at multiples of the phonon period.

description: This paper discusses the potential of ICT to support reflective learning for professionals. We aggregated data collected in 20 field studies with 12 different applications, involving a total of 321 participants. The applications addressed individual reflection as well as collaborative reflection. Such a systematic analysis with different applications used across industry sectors and companies is unique in the current literature on computer-supported reflective learning in the workplace. Primarily, we assessed the reaction to reflection applications and their effectiveness regarding learning, behaviour change, and organisational impact. In addition, we investigated differences with respect to work experience. Results show that users had a positive reaction to the apps and perceived their use to be beneficial for their work by using them. In collaborative reflection an inexperienced employee can benefit from the experiences and perspectives of more experienced (co-)workers. In contrast, individual reflection was more profitable for more experienced workers. Notwithstanding the overall positive results, the actual implementation of reflection applications requires careful adaptation to the specific organisational and situational context, as well as introductory and accompanying measures to assure efficient and beneficial usage of the tools.

description: We analyse liquid-crystalline ordering in vertically vibrated monolayers of cylinders confined in a circular cavity. Short cylinders form tetratic arrangements with C$_4$ symmetry. This symmetry, which is incompatible with the geometry of the cavity, is restored by the presence of four point defects with total topological charge $+4$. Equilibrium Monte Carlo simulations predict the same structure. A new method to measure the elastic properties of the tetratic medium is developed which exploits the clear similarities between the vibrated dissipative system and the thermal equilibrium system. Our observations open up a new avenue to investigate the formation of defects in response to boundary conditions, an issue which is very difficult to realize in colloidal or molecular systems.

description: We study the transport properties of a three dimensional atomic-scale contact in the ballistic regime. The results for the conductance and related transmission eigenvalues show how the properties of the ideal semi-infinite leads (i.e. measuring device) as well as the coupling between the leads and the conductor influence the transport in a two-probe geometry. We observe the evolution from conductance quantization to resonant tunneling conductance peaks upon changing the hopping parameter in the disorder-free tight-binding Hamiltonian which describes the leads and the coupling to the sample.
