description: We investigate the extrinsic spin Hall effect in the electron gas model due to magnetic impurities, by focusing on Ce- and Yb-impurities. In the dilute limit, the skew scattering term dominates the side jump term. For Ce-impurities, the spin Hall angle $α_{\rm SH}$ due to skew scattering is given by $-8π\sinδ_2/7$, where $δ_2 (\ll 1)$ is the phase shift for$d (l=2)$ partial wave. Since $α_{\rm SH}$ reaches $O(10^{-1})$ if $δ_2 \simge 0.03$, the spin Hall effect is anticipated to be considerable in metals with rare-earth impurities. The giant extrinsic SHE originates from the large orbital angular momentum, which is also significant for the intrinsic SHE.

description: Image annotation and large annotated datasets are crucial parts within the Computer Vision and Artificial Intelligence fields.At the same time, it is well-known and acknowledged by the research community that the image annotation process is challenging, time-consuming and hard to scale. Therefore, the researchers and practitioners are always seeking ways to perform the annotations easier, faster, and at higher quality. Even though several widely used tools exist and the tools' landscape evolved considerably, most of the tools still require intricate technical setups and high levels of technical savviness from its operators and crowdsource contributors. In order to address such challenges, we develop and present BRIMA -- a flexible and open-source browser extension that allows BRowser-only IMage Annotation at considerably lower overheads. Once added to the browser, it instantly allows the user to annotate images easily and efficiently directly from the browser without any installation or setup on the client-side. It also features cross-browser and cross-platform functionality thus presenting itself as a neat tool for researchers within the Computer Vision, Artificial Intelligence, and privacy-related fields.
Collisional processes and size distribution in spatially extended debris discs

description: We present a new multi-annulus code for the study of collisionally evolving extended debris discs. We first aim to confirm results obtained for a single-annulus system, namely that the size distribution in "real" debris discs always departs from the theoretical collisional equilibrium $dN\proptoR^{-3.5}dR$ power law, especially in the crucial size range of observable particles (<1cm), where it displays a characteristic wavy pattern. We also aim at studying how debris discs density distributions, scattered light luminosity profiles, and SEDs are affected by the coupled effect of collisions and radial mixing due to radiation pressure affected small grains. The size distribution evolution is modeled from micron-sized grains to 50km-sized bodies. The model takes into account the crucial influence of radiation pressure-affected small grains. We consider the collisional evolution of a fiducial a=120AU radius disc with an initial surface density in $Σ(a)\propto a^α$. We show that the system's radial extension plays a crucial role: in most regions the collisional and size evolution of the dust is imposed by small particles on eccentric or unbound orbits produced further inside the disc. The spatial distribution of small grains strongly departs from the initial profile, while the bigger objects, containing most of the system's mass, still follow the initial distribution. This has consequences on the scattered--light radial profiles which get significantly flatter, and we propose an empirical law to trace back the distribution of large unseen parent bodies from the observed profiles. We finally provide empirical formula for the collisional size distribution and collision timescale that can be used for future debris disc modeling.

Predictive protocol of flocks with small-world connection pattern

description: By introducing a predictive mechanism with small-world connections, we propose a new motion protocol for self-driven flocks. The small-world connections are implemented by randomly adding long-range interactions from the leader to a few distant agents, namely pseudo-leaders. The leader can directly affect the pseudo-leaders, thereby influencing all the other agents through them efficiently. Moreover, these pseudo-leaders are able to predict the leader's motion several steps ahead and use this information in decision making towards coherent flocking with more stable formation. It is shown that drastic improvement can be achieved in terms of both the consensus performance and the communication cost. From the industrial engineering point of view, the current protocol allows for a significant improvement in the cohesion and rigidity of the formation at a fairly low cost of adding a few long-range links embedded with predictive capabilities. Significantly, this work uncovers an important feature of flocks that predictive capability and long-range links can compensate for the insufficiency of each other. These conclusions are valid for both the attractive/repulsive swarm model and the Vicsek model.

description: LUXE (Laser Und XFEL Experiment) is a new experiment in planning at DESY Hamburg using the electron beam of the European XFEL. LUXE is intended to study collisions between a high-intensity optical laser and 16.5 GeV electrons from the XFEL electron beam, as well as collisions between the optical laser and high-energy secondary photons. The physics objective of LUXE are processes of quantum electrodynamics (QED) at the strong-field frontier, where the electromagnetic field of the laser is above the Schwinger limit. In this regime, QED is non-perturbative. This manifests itself in the creation of physical electron-positron pairs from the QED vacuum, similar to Hawking radiation from black holes. LUXE intends to measure the positron production rate in an unprecedented laser intensity regime. An overview of the LUXE experimental setup and its challenges will be given, followed by a discussion of the expected physics reach in the context of testing QED in the non-perturbative regime.

description: Using a current-current correlation function (CF), the photon polarization tensor is calculated for a rotating hot and dense QCD medium. The spectral function (SF) and the dilepton rate (DR) are estimated therefrom. Numerical results show that both SF and DR are enhanced in a rotating medium, especially in a low invariant mass region. SF and DR are also explored in the consequences of the interplay among the angular velocity, temperature and chemical potential. We also estimated the electromagnetic screening by calculating the Debye mass and it shows a suppression for a rotating QCD medium. The most interesting observation is the azimuthal anisotropy of the dilepton production, i.e, the elliptic flow $v_{2}$ of the lepton pair induced by the rotation as an external field. The competition between the centrifugal effect and the spin polarization effect due to rotation results in a convex down behaviour of the elliptic flow as a function of the transverse momentum in a relatively large magnitude of angular velocity. It is noticed that quark spin polarization induces a negative $v_2$ in the case of large angular velocity.

Comstock.” Beutenmüller (1897: 17) noted “last summer Mr. Doll raised a single specimen [of elda] from a larva found on Long Island, N.Y. It is, without doubt, nothing more than a gray variety of C. relicta. Mr. Palm already called attention to this fact (Journ. N. Y. Entomological Soc., I, p. 21.).” Barnes and McDunnough stated (1918: 20) that elda was “at best a mere geographical race found on the Pacific Coast from British Columbia to Oregon … it is apparently best defined on Vancouver Island, B.C., for specimens before us from the interior of Washington State can scarcely be separated from phrynia.” Since we have also seen specimens referable to elda from other eastern North American localities, we place C. elda as a synonym of C. relicta Walker, [1858].

Geometría dinámica del tiempo: hacia una teoría unificada sin fuerzas clásicas

description: Este trabajo presenta una nueva interpretación de la física basada en un principio radicalmente simple: el tiempo no es una variable externa, sino una propiedad emergente creada por el movimiento y la masa. A partir de este principio, se reconstruyen las nociones de masa, carga, repulsión, atracción y confinamiento, sin necesidad de fuerzas clásicas ni partículas fundamentales.

El modelo propuesto se basa en la deformación local del campo de tiempo inducida por la presencia de materia y movimiento. Mediante simulaciones numéricas y visualizaciones tridimensionales, se demuestra que es posible reproducir interacciones emergentes, trayectorias orbitales, e incluso la formación de estructuras estables como el átomo, sin recurrir a campos electromagnéticos ni gravitatorios explícitos.

Esta publicación, está centrada en la dinámica del átomo sin usar cargas únicamente a través de la geometría inducida por el tiempo emergente.

El enfoque aquí presentado busca simplificar y unificar la física desde un marco geométrico-temporal profundo, accesible y conceptualmente elegante.

description: With event-driven algorithms, especially the spiking neural networks (SNNs), achieving continuous improvement in neuromorphic vision processing, a more challenging event-stream-dataset is urgently needed. However, it is well known that creating an ES-dataset is a time-consuming and costly task with neuromorphic cameras like dynamic vision sensors (DVS). In this work, we propose a fast and effective algorithm termed Omnidirectional Discrete Gradient (ODG) to convert the popular computer vision dataset ILSVRC2012 into its event-stream (ES) version, generating about 1,300,000 frame-based images into ES-samples in 1000 categories. In this way, we propose an ES-dataset called ES-ImageNet, which is dozens of times larger than other neuromorphic classification datasets at present and completely generated by the software. The ODG algorithm implements an image motion to generate local value changes with discrete gradient information in different directions, providing a low-cost and high-speed way for converting frame-based images into event streams, along with Edge-Integral to reconstruct the high-quality images from event streams. Furthermore, we analyze the statistics of the ES-ImageNet in multiple ways, and a performance benchmark of the dataset is also provided using both famous deep neural network algorithms and spiking neural network algorithms. We believe that this work shall provide a new large-scale benchmark dataset for SNNs and neuromorphic vision.

description: Dwarf nova outbursts result from enhanced mass transport through the accretion disc of a cataclysmic variable system. We assess the question of whether these outbursts are caused by an enhanced mass transfer from the late-type main sequence star onto the white dwarf (so-called mass transfer instability model, MTI) or by a thermal instability in the accretion disc (disc instability model, DIM). We compute non-LTE models and spectra of accretion discs in quiescence and outburst and construct spectral time sequences for discs over a complete outburst cycle. We then compare our spectra to published optical spectroscopy of the dwarf nova SS Cygni. In particular, we investigate the hydrogen and helium line profiles that are turning from emission into absorption during the rise to outburst. The evolution of the hydrogen and helium line profiles during the rise to outburst and decline clearly favour the disc-instability model. Our spectral model sequences allow us to distinguish inside-out and outside-in moving heating waves in the disc of SS Cygni, which can be related to symmetric and asymmetric outburst light curves, respectively.

description: The MOST (Microvariability and Oscillations of Stars) satellite has discovered SPBe (Slowly Pulsating Be) oscillations in the stars HD 127756 (B1/B2 Vne) and HD 217543 (B3 Vpe). For HD 127756, 30 significant frequencies are identified from 31 days of nearly continuous photometry; for HD 217543, up to 40 significant frequencies from 26 days of data. In both cases, the oscillations fall into three distinct frequency ranges, consistent with models of the stars. The variations are caused by nonradial g-modes (and possibly r-modes) distorted by rapid rotation and excited by the opacity mechanism near the iron opacity bump. A comparison of pulsation models and observed frequency groups yields a rotation frequency for each star, independently of vsini. The rotation rates of these stars, as well as those of the SPBe stars previously discovered by MOST, HD 163868 and $β$ CMi, are all close to their critical values.

description: Magnetic fields in the early universe can significantly alter the thermal evolution and the ionization history during the dark ages. This is reflected in the 21 cm line of atomic hydrogen, which is coupled to the gas temperature through collisions at high redshifts, and through the Wouthuysen-Field effect at low redshifts. We present a semi-analytic model for star formation and the build-up of a Lyman alpha background in the presence of magnetic fields, and calculate the evolution of the mean 21 cm brightness temperature and its frequency gradient as a function of redshift. We further discuss the evolution of linear fluctuations in temperature and ionization in the presence of magnetic fields and calculate the effect on the 21 cm power spectrum. At high redshifts, the signal is increased compared to the non-magnetic case due to the additional heat input into the IGM from ambipolar diffusion and the decay of MHD turbulence. At lower redshifts, the formation of luminous objects and the build-up of a Lyman alpha background can be delayed by a redshift interval of 10 due to the strong increase of the filtering mass scale in the presence of magnetic fields. This tends to decrease the 21 cm signal compared to the zero-field case. In summary, we find that 21 cm observations may become a promising tool to constrain primordial magnetic fields.

description: Sterile neutrinos with masses $\sim 0.1$ eV or higher would play an important role in astrophysics and cosmology. We explore possible signatures of such sterile neutrinos at long baseline experiments. We determine the neutrino conversion probabilities analytically in a 4-neutrino framework, including matter effects, treating the sterile mixing angles $θ_{14}, θ_{24}, θ_{34}$, the deviation of $θ_{23}$ from maximality,as well as $θ_{13}$ and the ratio $Δm^2_\odot/Δm^2_{atm}$ as small parameters for a perturbative expansion. This gives rise to analytically tractable expressions for flavor conversion probabilities from which effects of these parameters can be clearly understood. We numerically calculate the signals at a neutrino factory with near and far detectors that can identify the lepton charge, and point out observables that can discern the sterile mixing signals. We find that clean identification of sterile mixing would be possible for $θ_{24}θ_{34} \gsim 0.005$ and $θ_{14} \gsim 0.06$ rad with the current bound of $θ_{13} < 0.2$ rad; a better $θ_{13}$ bound would allow probing smaller values of sterile mixing. We also generalize the formalism for any number of sterile neutrinos, and demonstrate that only certain combinations of sterile mixing parameters are relevant irrespective of the number of sterile neutrinos. This also leads to a stringent test of the scenario with multiple sterile neutrinos that currently is able to describe all the data from the short baseline experiments, including LSND and MiniBOONE.

description: We report on the fabrication of micro-axicons made of glass by laser-assisted wet etching (LAE) and laser polishing. The employed technique, relying on an efficient direct-writing process by femtosecond laser, allows revealing high fidelity profiles while etched in a heated potassium hydroxide (KOH) solution. The remaining surface roughness is then smoothened by carbon dioxide (CO2) laser polishing. Such polishing is limited to the skin of the component so that the tip is only slightly rounded, with a radius of curvature of nearly 200 μm. It is then shown with 500 μm-diameter axicons that the quasi-Bessel beam is generated closely after the tip, and features a 5.3 μm diameter maintained over a propagation distance of almost 3.5 mm.

description: Recently it was discovered that altering the shape of the meta stable and unstable branches of an equation of state (EOS) can greatly improve the numerical accuracy of liquid and gas densities in the pseudopotential method. Inspired by this approach we develop an improved approach that is benchmarked for both equilibrium and non-equilibrium situations. We show here that the original approach reduces the method stability in non-equilibrium situations. Here we propose a new procedure to replace the metastable and unstable regions of these EOS by alternative functions. Our approach does not affects the coexistence densities or the speed of sound of the liquid phase while maintaining continuity of the sound speed in the pressure-density curve. Using this approach we were able to reduce the relative error of the planar interface vapor density compared to the thermodynamic consistent value by increasing the vapor phase sound speed. To allow for the benchmarking of dynamic results we also developed a finite difference method (FD) that solves the same macroscopic conservation equation as the pseudopotential lattice Boltzmann method (LBM). With this FD scheme we are able to perform mesh refinement and obtain reference solutions for the dynamic tests. We observed excellent agreement between the FD solutions and our proposed scheme. We also performed a detailed study of the stability of the methods using simulations of a droplet impacting on a liquid film for reduced temperatures down to 0.35 with Reynolds number of 300. Our approach remains stable for a density ratio up to $3.38\cdot10^{4}$.

Brower’s (1976: 37) brief diagnosis stated that C. erichi was “well separated from francisca Hy. Edwards, and from the more northern complex of mariana, Hy. Edwards, edwardsi Kuznesov and eldoradensis Beutenmüller. Larvae of erichi (named for the chief collector), two broods, lost in the last instar the dark brown patch on the abdominal hump, while larvae of francisca kept their patch.” Our rearing work and comparison of types indicate that C. francisca H. Edwards, 1880 is conspecific with C. hermia H. Edwards, 1880, not C. californica Edwards, 1864; and that C. erichi is an infrapopulational form of C. californica. Specimens referable to C. erichi occur sporadically throughout the geographic range of C. californica, but are most prevalent in the mountains of southern California.

description: As modern technologies are becoming more and more sophisticated, the modern business environment is becoming increasingly competitive. Businesses nowadays have access to an extensive scale of data, and they can make more informed decisions than ever before. This has made the modern business environment excruciatingly competitive and businesses that operate in the traditional way can no longer survive, particularly in industries such as Foreign Exchange (Forex). This is because the companies in the Forex industry utilise cutting edge technologies in their business processes and achieving cross-department strategic alignment is critical to the success of a Forex firm. A wide number of existing studies investigated the factors of strategic alignment in the context of big companies, however, an extensive review of the literature indicated that no empirical research previously investigated Forex SMEs to explore the factors of strategic alignment as well as the challenges SMEs face whilst achieving strategic alignment. This research, therefore, seeks to fill the existing knowledge gap by exploring the critical success factors that are essential for achieving harmonious strategic alignment between business strategy and IT strategy by investigating a UK-based Forex SME as a case. This research adopted the interpretivist research philosophy and utilised a qualitative research design by interviewing 16 participants that are currently working in various departments of the case organisation. In order to analyse the research data, thematic analysis was conducted whilst utilising NVivo 12 pro. This research revealed that factors such as Communication maturity, Competency maturity, IT governance maturity, Scope and architecture of the IT maturity, Partnership maturity, Skills maturity, and Web systems maturity play critical roles in terms of achieving strategic alignment in Forex SMEs. Besides, this research also revealed numerous challenges Forex SMEs face whilst achieving strategic alignment. They include lack of senior management commitment, lack of coordination between departments, resistance to change culture, and slow decisionmaking. The findings of this research make significant contributions to the literature by reconceptualising the existing Luftman’s strategic alignment maturity model in the context of Forex SMEs. The findings also make contributions to the literature by adding new insights and filling the existing knowledge gap.

description: The vast majority of proteins are intrinsically fluorescent in the ultraviolet, thanks to the emission from their tryptophan and tyrosine amino-acid constituents. However, the protein autofluorescence quantum yields are generally very low due to the prevailing quenching mechanisms by other amino acids inside the protein. This motivates the interest to enhance the radiative emission rate of proteins using nanophotonic structures. Although there have been numerous reports of Purcell effect and local density of optical states (LDOS) control in the visible range using single dipole quantum emitters, the question remains open to apply these concepts in the UV on real proteins containing several tryptophan and tyrosine amino acids arranged in a highly complex manner. Here, we report the first complete characterization of the Purcell effect and radiative rate enhancement for the UV intrinsic fluorescence of label-free \b{eta}-galactosidase and streptavidin proteins in plasmonic aluminum nanoapertures. We find an excellent agreement with a calibration performed using a high quantum yield UV fluorescent dye. Demonstrating and intensifying the Purcell effect is essential for the applications of UV plasmonics and the label-free detection of single proteins.

Investigating key factors investigating effective cybersecurity governance: a study of Pakistan's private commercial banks
Creators: name: Faryal
Publisher: name: Zenodo

description: In the contemporary digital landscape, the effective governance of e-banking information systems poses a global challenge. Similarly, despite the financial soundness of the banking industry in Pakistan, its vulnerability to cyber threats remains a significant concern. This study aims to identify key factors influencing cybersecurity governance in Private Commercial Banks of Pakistan (PCBP, Lahore), exploring internal and external challenges, and providing practical recommendations. The theoretical framework of this thesis draws on the institutional logics perspective to highlight how stakeholders' actions reshape the social institutions governing cybersecurity in the banking sector. The study also incorporates the Technology Acceptance Model (TAM) and motivation concepts alongside the three lines of defence model. This comprehensive approach emphasizes institutional actions for robust cybersecurity governance in banks. Empirically, findings based on 21 semi-structured interviews across 13 PCBP highlight an increasing threat of social engineering linked to customer awareness. In particular, digital literacy was proven more effective than formal degrees in combating cyberthreats. The study advocates immediate nationwide awareness programs by the government to instil a culture of cybersecurity, acting as a deterrent against cybercriminals. Moreover, hurdles such as insufficient legislation, the capabilities of law enforcement agents, and corrupt agents were found to impede effective cybercrime prevention. The findings of the study indicate that the State Bank of Pakistan (SBP) faces challenges due to a lack of cybersecurity experts and experienced audit teams, enabling banks to manipulate performance superficially. Furthermore, inadequate cybersecurity training for directors contributes to governance issues, fostering cyberthreats like social engineering, ATM skimming, malware, and DDoS attacks. The study also highlights the potential threat of deepfake technology in the context of low cybersecurity awareness in Pakistan's banking sector. In summary, this thesis advocates a holistic approach involving collaboration between PCBP, SBP, and the government to enhance cybersecurity governance. Leveraging institutional logics, the proposed framework holds potential applicability to developing countries grappling with similar cybersecurity challenges.

description: The Weather4cast 2021 competition gave the participants a task of predicting the time evolution of two-dimensional fields of satellite-based meteorological data. This paper describes the author's efforts, after initial success in the first stage of the competition, to improve the model further in the second stage. The improvements consisted of a shallower model variant that is competitive against the deeper version, adoption of the AdaBelief optimizer, improved handling of one of the predicted variables where the training set was found not to represent the validation set well, and ensembling multiple models to improve the results further. The largest quantitative improvements to the competition metrics can be attributed to the increased amount of training data available in the second stage of the competition, followed by the effects of model ensembling. Qualitative results show that the model can predict the time evolution of the fields, including the motion of the fields over time, starting with sharp predictions for the immediate future and blurring of the outputs in later frames to account for the increased uncertainty.

description: The work focuses on software development based on the TRICK B2B multiservice marketplace platform architecture and specification (D4.1) in the scope of the TRICK project. The inputs of this task are the requirements collected in WP1, the specification guidelines defined in D2.1, the API definitions of the Security Broker (T2.4) and the Ecosystem Data Manager (T2.3). The outcome of this task is the TRICK B2B multiservice marketplace platform. It is a composition of microservices that provide the functionality of a B2B Marketplace for digital services as a whole.TRICK B2B multiservice marketplace platform represents a B2B marketplace that contains loosely coupled TRICK business services. From the user perspective, the core function is to consume and publish TRICK business services. For that purpose, user interfaces and back-end services have been implemented. In doing so, consuming a service is supported by a keyword and a faceted search. For each service, a summary, a detail page and ratings are provided. The second core function is the publication of TRICK business services. For that purpose, a publishing process has been implemented using a wizard. In addition, a second web application is in place that supports the review process of committed TRICK business services to establish quality assurance for the services.

description: Additional file 10: Figure S3. Distribution of alternative splicing prevalence and level (ASP/L) against cell type number (CTN) and mean intron size across all 37 species used in this study. (A) The red points represent three outlier species that have higher ASP but lower CTN. ASP was calculated using all RNA-Seq data for each species, LeafCutter software, and the Bin 500 method. Spearman’s ρ = 0.63, P = 1.27e-05. (B) The scatter plots depict the correlation between mean intron size and two species-level complexity proxies, organism complexity (CTN; the blue points and the y-axis on the left) and alternative splicing level (ASL; the red points and the y-axis on the right). ASL was calculated using the LeafCutter tool and a Bin500 gene number. Spearman’s ρ between mean intron size and CTN is 0.36 (P = 0.02), and between mean intron size and ASL is 0.46 (P = 0.0026).

description: The difference in density profiles of the contributions from different density peaks to dark matter halos results in certain expectations about the Milky Way's stellar halo. We cut our simulated halo stars into two populations: those forming before/during the last major merger, and those accreted after the last major merger. The former population are more centrally located at z=0, while stars forming in low mass late forming proto-galaxies are spread through the halo. A difference in observed binding energy distinguishes these two populations. We look at possible chemical abundance signatures of the two populations. We also show that galaxies forming in isolated low sigma peaks will form from primordial material. Thus, even though the oldest stars are centrally concentrated as they originated in the early collapsing, densest regions, primordial stars would be found distributed throughout the halo. Thus, the lack of observed metal free stars can be taken as directly constraining the Population III IMF, and the lowest metallicity observed stars can be interpreted as holding clues to the chemical yields of Pop III stars.

description: Strategies that utilise the interference effects within $B^{\pm} \to DK^{\pm}$ decays hold great potential for improving our sensitivity to the CKM angle $γ$. However, in order to exploit fully this potential, detailed knowledge of the D meson decay structure is required. This essential information can be obtained from the quantum correlated $ψ(3770)$ datasets at CLEO-c. Results of such analyses involving the decay mode $D \to Kπππ$, and their importance in the context of LHCb, will be presented.
