title: What Effects Do Large Language Models Have on Cybersecurity
Creators: name: Marshall, Josiah
Publisher: name: Old Dominion University Libraries
Year: 2023

description: Large Language Models (LLMs) are artificial intelligence (AI) tools that can process, summarize, and translate texts and predict future words in a sentence, letting the LLM generate sentences similar to how humans talk and write. One concern that needs to be flagged is that, often, the content generated by different LLMs is inaccurate. LLMs are trained on code that can be used to detect data breaches, detect ransomware, and even pinpoint organizational vulnerabilities in advance of a cyberattack. LLMs are new but have unbelievable potential with their ability to generate code that brings awareness to cyber analysts and IT professionals. That is why cybersecurity professionals must raise awareness of the threats these LLMs present and what are the best ways to minimize these threats.

description: Introducing the plasma texturization into industrial solar cell fabrication process is one option to increase the efficiency of solar cells and to reduce the costs for cell fabrication, the main topics in photovoltaics.  The plasma texturization process itself must be applicable for mass production and should have a lower consumption of chemicals and thus a lower impact on environmental pollution compared to existing wet texturization processes.
The implementation of single side plasma texturization into standard solar cell fabrication was tested successfully in the Roth & Rau pilot line. Due to the lower weighted reflectivity achieved by plasma texturization (compared to wet texturization) with the new MAiATEX tool (Roth & Rau MAiA® 2nd generation platform) an increased cell efficiency could be shown.  This real single side process can be applied for all Si wafer surfaces (i.e. mono-, quasimono-, multicrystalline, string ribbon, …) independent from wafering process (SiC or diamond wire sawing, epitaxy, cleaving, …) and is suitable for very thin wafers. The surface topology size realized by plasma texturization is in sub µm scale and surface damage could not be observed. It was shown, using this technology, that approximately 5% more light is coupled into the solar cell leading to an increased cell efficiency (up to 0.5 % absolute). Further industrial benefit is to combine inline plasma texture with other inline plasma processes (PECVD of doping or antireflection and passivation layers).

description: We present a combined experimental and theoretical study of the evolution of the low-temperature Fermi surface of lead telluride, PbTe, when holes are introduced through sodium substitution on the lead site. Our Shubnikov-de-Haas measurements for samples with carrier concentrations up to $9.4\times10^{19}$cm$^{-3}$ (0.62 Na atomic $\%$) show the qualitative features of the Fermi surface evolution (topology and effective mass) predicted by our density functional (DFT) calculations within the generalized gradient approximation (GGA): we obtain perfect ellipsoidal L-pockets at low and intermediate carrier concentrations, evolution away from ideal ellipsoidicity for the highest doping studied, and cyclotron effective masses increasing monotonically with doping level, implying deviations from perfect parabolicity throughout the whole band. Our measurements show, however, that standard DFT calculations underestimate the energy difference between the L-point and $Σ$-line valence band maxima, since our data are consistent with occupation of a single Fermi surface pocket over the entire doping range studied, whereas the calculations predict an occupation of the $Σ$-pockets at higher doping. Our results for low and intermediate compositions are consistent with a non-parabolic Kane-model dispersion, in which the L-pockets are ellipsoids of fixed anisotropy throughout the band, but the effective masses depend strongly on Fermi energy.

description: Si3N4-nanolayers were prepared by non-reactive magnetron sputtering in an Ar atmosphere. A
previously synthesized silicon nitride was used as a solid-state target. The deposition was carried out on a cold
substrate of p-Si (100) with a resistivity of 2 Ohmcm. The film thicknesses were up to 20 nm with the height of the
structural units of about 1-2 nm. Vibrations at frequencies of 288, 307 and 347 cm-1 in the spectrum of Raman
scattering were detected, which correspond to the cubic modification of silicon nitride. The shape of the spectrum is
characteristic for the nanocrystalline state. A heterostructure was obtained by the deposition of a Si3N4 nanolayer on
the surface of p-Si wafer and a p-Si/n-Si3N4 nanolayer photovoltaic cell was fabricated. The barrier height at the
Si/Si3N4 interface is 0.9-1.0 eV. The investigation of the electrical and photoelectric properties of such devices shows
that the Si/Si3N4 interface has a metal-insulator-semiconductor surface barrier structure with an inversion layer
formed in silicon. The spectral dependence of the Si/Si3N4 solar cells photosensitivity entirely corresponds to the
respective characteristic of the Si solar cell. Load I-V characteristics of the elaborated photovoltaic devices
demonstrate conversion efficiencies of 6.38%.

description: Contacting boron emitter by screen printing metallization is one of the most challenging criteria for the industrialization of high
efficiency n-type silicon bifacial solar cells. However due to its easy handling and mass production proven capabilities, screen printing is still the
most suited low-cost method to contact p+ surfaces. In this study, we determined the different losses coming from metallization on this solar
cells concept. We then suggest the related guidelines to trend to the most suited low cost screen printed metallization by finding the optimum
between current collection and recombination losses.
The binding energy produced within the framework of the accretion of millisecond pulsars

description: The role and implication of binding energy through the accretion-induced collapse (AIC) of accreting white dwarfs (WDs) for the production of millisecond pulsars (MSPs) are investigated. I examine the binding energy model due to the dynamical process in close binary systems and investigating the possible mass of the companion sufficient to induce their orbital parameters. The deterministic nature of this interaction has a strong sensitivity to the equation of state of the binary systems (where the compactness of a neutron star is proportional to the amount of binding energy) associated with their initial conditions. This behavior will mimic the commonly assumed mass and amount of accreted matter under the instantaneous mass loss ($ΔM \sim 0.18M_{\odot}$). As a result, this will indicate an increase in the MSP's gravitational mass due to angular momentum losses. The outcome of such a system will then be a circular binary MSP in which the companion is a low-mass WD, thus distinguishing the binary formation scenarios. In addition, the results of this work could provide constraints on the expected mass and binding energy of a neutron star based on the accretion rate

description: A simplified fabrication process for >20.5% efficient, ion implanted, double side contacted boron rear
emitter solar cells is presented. The fully implanted rear emitter on n-type (nFIRE) solar cells can achieve high
efficiency while utilizing a screen printing based low-cost and mature metallization process. The junction formation
and passivation process is greatly simplified by ion implantation. nFIRE process can be easily integrated into existing
process flows for Al-BSF or pPERC cells and is also extendible to higher efficiently IBC cells due to similarities in
cell precursors. Device parameters that are crucial to realize high efficiency for rear junction devices are identified
through modeling and a path to 21.5% efficient cells is demonstrated. In this paper we present >20.5% efficient boron
rear emitter solar cells with SiO2/SiNx passivation and low-cost, low-Ag usage, screen printed metallization process
on 239 cm2, solar grade n-type Cz material.

I show that the method works exceedingly well at two and three loops where exact results are already known. I then present a calculation of the massive cusp anomalous dimension using its asymptotics at four loops, and I provide a detailed study of the results for different values of the number of flavors and for separate color structures. The method can be further extended and applied to higher numbers of loops.

description: In p-type c-Si solar cells, selective emitter structures generated by emitter etch-back (EEB) have been
introduced in recent years in order to minimize electrical losses in the phosphorous emitter being one of the dominant
factors limiting the performance of standard screen-printed p-type c-Si solar cells. In this work, a homogeneously or
selectively etched-back boron emitter is demonstrated to provide additional benefits yielding an enhanced conversion
efficiency in n-type Si solar cells.
By means of subsequent B-EEB, contacting and recombination properties of B emitters dependent on their sheet
resistance, surface concentration, and profile depth are studied indicating the latter to be the crucial parameter. Based
on this, the characteristics of the optimal B emitter regarding low saturation current density and low specific contact
resistivity are determined for the cases of homogeneous and selective etch-back.
By employing the selectively etched-back B emitter in initial solar cells, a VOC gain of 5 mV and a significant
shunting reduction compared with homogeneously doped devices is achieved.

description: Bistability in magnetism has been extensively used, in particular to store information. Here we propose an alternative route by using tetrastable magnetic domains. Using numerical and analytical calculations we show that a spin chain with a canting angle of π/4 possesses four energy-equivalent states. We discuss the static properties of such chain such as the profile and the energy of the domain walls as they govern the relaxation of the magnetization. The realisation of such spin chain could enable the encoding of the information on four bits which is a potential alternative toward the increase of storage density.

description: We use archival ALMA observations of the HCN and CO $J=1-0$ transitions, in addition to the radio continuum at 93 GHz, to assess the relationship between dense gas, star formation, and gas dynamics in ten, nearby (U)LIRGs and late-type galaxy centers. We frame our results in the context of turbulent and gravoturbulent models of star formation to assess if the HCN/CO ratio tracks the gravitationally-bound, star-forming gas in molecular clouds ($f_\mathrm{grav}$) at sub-kpc scales in nearby galaxies. We confirm that the HCN/CO ratio is a tracer of gas above $n_\mathrm{SF}\approx10^{4.5}$ cm$^{-3}$, but the sub-kpc variations in HCN/CO do not universally track $f_\mathrm{grav}$. We find strong evidence for the use of varying star formation density threshold models, which are able to reproduce trends observed in $t_\mathrm{dep}$ and $ε_\mathrm{ff}$ that fixed threshold models cannot. Composite lognormal and powerlaw models outperform pure lognormal models in reproducing the observed trends, even when using a fixed powerlaw slope. The ability of the composite models to better reproduce star formation properties of the gas provides additional indirect evidence that the star formation efficiency per free-fall time is proportional to the fraction of gravitationally-bound gas.

description: High efficiency back-junction back-contact silicon solar cells using 6” n-type Cz material and an industrial feasible process flow based on hybrid junction formations and all screen printed metallization are presented. The boron emitter and FSF/BSF were formed by diffusion technique with BCl3 precursor and PH3 ion-implantation respectively. The interdigitated pattern was formed by single dielectric masking and opening for ion-implantation. Both of front and rear sides were passivated by silicon oxide and nitride stack. Excellent current collection was achieved due to an optimized FSF and reduced electrical shading effect. Also, the FF had been improved by the study of the metal contact ratio and pitch effect. The large area cell efficiency up to 21.6% was realized and zero LID had been proved.

description: The aim of this note is to generalize the notion of Fredholm operator to an arbitrary $C^*$-algebra. Namely, we define "finite type" elements in an axiomatic way, and also we define Fredholm type element $a$ as such element of a given $C^*$-algebra for which there are finite type elements $p$ and $q$ such that $(1-q)a(1-p)$ is "invertible". We derive index theorem for such operators. In applications we show that classical Fredholm operators on a Hilbert space, Fredholm operators in the sense of Breuer, Atiyah and Singer on a properly infinite von Neumann algebra, and Fredholm operators on Hilbert $C^*$-modules over an unital $C^*$-algebra in the sense of Mishchenko and Fomenko are special cases of our theory.

description: We describe new functionality in the GYRE stellar oscillation code for modeling tides in binary systems. Using a multipolar expansion in space and a Fourier-series expansion in time, we decompose the tidal potential into a superposition of partial tidal potentials. The equations governing the small-amplitude response of a spherical star to an individual partial potential are the linear, non-radial, non-adiabatic oscillation equations with an extra inhomogeneous forcing term. We introduce a new executable, gyre_tides, that directly solves these equations within the GYRE numerical framework. Applying this to selected problems, we find general agreement with results in the published literature but also uncover some differences between our direct solution methodology and the modal decomposition approach adopted by many authors. In its present form gyre_tides can model equilibrium and dynamical tides of aligned binaries in which radiative diffusion dominates the tidal dissipation (typically, intermediate and high-mass stars on the main sequence). Milestones for future development include incorporation of other dissipation processes, spin-orbit misalignment, and the Coriolis force arising from rotation.
description: 15 pages, 8 figures, accepted for publication in ApJ; This new functionality, along with GYRE version 7.0, will be release in a few days from today (Jan 16th, 2023)

description: Solar cell concepts like the IBC concept based on locally doped areas promise a high efficiency of
more than 24%. This, however, imposes two major challenges: the capability to create these locally doped regions
and – which is often forgotten – the capability to check the actual electronic quality of these sometimes microscopic
regions (doping level etc.). In order to keep manufacturing costs small, the approach of local doping by ink jetting
boron-containing inks is chosen for this contribution. Though liquid deposited doping sources exhibit inhomogeneous
properties by itself, the spatial resolved quality control is of utmost importance. Therefore, Kelvin probe force
microscopy (KPFM) is applied to map the surface potential and thus the local doping level. Using this technique,
some special features of ink jetted boron-containing inks and driven-in emitters like edge sharpness, dopant
distribution among other topics are discussed.

In this paper, a numerical invariant of the graph $Θ$ that determines the dimension of $A_Θ$ is found. Namely, we prove that the Gelfand-Kirillov dimension of $A_Θ$ is the sum of the number of cyclic subgraphs of $Θ$ and the number of oriented paths of a special type in the graph, each counted certain specific number of times.

description: Traditional taxi systems in metropolitan areas often suffer from inefficiencies due to uncoordinated actions as system capacity and customer demand change. With the pervasive deployment of networked sensors in modern vehicles, large amounts of information regarding customer demand and system status can be collected in real time. This information provides opportunities to perform various types of control and coordination for large-scale intelligent transportation systems. In this paper, we present a receding horizon control (RHC) framework to dispatch taxis, which incorporates highly spatiotemporally correlated demand/supply models and real-time GPS location and occupancy information. The objectives include matching spatiotemporal ratio between demand and supply for service quality with minimum current and anticipated future taxi idle driving distance. Extensive trace-driven analysis with a data set containing taxi operational records in San Francisco shows that our solution reduces the average total idle distance by 52%, and reduces the supply demand ratio error across the city during one experimental time slot by 45%. Moreover, our RHC framework is compatible with a wide variety of predictive models and optimization problem formulations. This compatibility property allows us to solve robust optimization problems with corresponding demand uncertainty models that provide disruptive event information.

Finite-size prethermalization at the chaos-to-integrable crossover

Year: 2023
Subjects: subject: 530 Physik

description: We investigate the infinite-temperature dynamics of the complex Sachdev-Ye-Kitaev model (SYK4) complemented with a single-particle hopping term (SYK2), leading to the chaos-to-integrable crossover of the many-body eigenstates. Due to the presence of the all-to-all connected SYK2 term, a nonequilibrium prethermal state emerges for a finite time window t_th∝2^(a/λ^2/5) that scales with the relative interaction strength λ, between the SYK terms before eventually exhibiting thermalization for all λ. The scaling of the plateau with λ is consistent with the many-body Fock-space structure of the time-evolved wave function. In the integrable limit, the wave function in the Fock space has a stretched exponential dependence on distance. On the contrary, in the SYK4 limit, it is distributed equally over the Fock-space points characterizing the ergodic phase at long times.

emitter has been optimized by PC2D simulation. The result shows that the variation of the metal coverage ratio
(MCR) would affect both the surface passivation and electrode-contact properties for p-type emitter in IBC solar cells.
We found that when Rc was ranging from 0.08 to 0.16 Ω•cm2, the MCR was optimized with a value of 25 % and 33%,
resulted in a highest energy-conversion efficiency. The dependence of both Voc-MCR and FF-MCR has been
simulated in order to explore the mechanism of the IBC solar cells.

description: Context. The classical "planetesimal" accretion scenario for the formation of planets has recently evolved with the idea that "pebbles", centimeter- to meter-sized icy grains migrating in protoplanetary disks, can control planetesimal and/or planetary growth. Aims. We investigate how pebble accretion depends on disk properties and affects the formation of planetary systems Methods. We construct analytical models of pebble accretion onto planetary embryos that consistently account for the mass and orbital evolution of the pebble flow and reflect disk structure. Results. We derive simple formulas for pebble accretion rates in the so-called "settling" regime for planetary embryos with more than 100 km in size. For relatively smaller embryos or in outer disk regions, the accretion mode is 3D, meaning that the thickness of the pebble flow must be taken into account, and resulting in an accretion rate that is independent of the embryo mass. For larger embryos or in inner regions, the accretion is in a 2D mode, i.e., the pebble disk may be considered to be infinitely thin. We show that the radial dependence of the pebble accretion rata is different (even the sign of the power-law exponent changes) for different disk conditions such as the disk heating source (viscous heating or stellar irradiation), the drag law (Stokes or Epstein, and weak or strong coupling), and in the 2D or 3D accretion modes. We also discuss the effect of the sublimation/destruction of icy pebbles inside the snow line. Conclusions. Pebble accretion easily produces a large diversity of planetary systems. In other words, to correctly infer the results of planet formation through pebble accretion, detailed prescriptions of disk evolution and pebble growth, sublimation/destruction and migration are required.

description: Filaments are an important part of star-forming interstellar clouds. Theie properties hold clues to their formation mechanisms and role in the star-formation process. We compare the properties of filaments in the Orion Molecular Cloud 3 (OMC-3), as seen in mid-infrared (MIR) absorption and far-infrared (FIR) dust emission. We calculated optical depth maps of the OMC-3 filaments based on the MIR absorption seen in Spitzer data and FIR dust emission observed with Herschel and the ArTéMiS instrument. The widths of the selected OMC-3 filament segments are in the range 0.03-0.1 pc, with similar average values seen in both MIR and FIR analyses. Compared to the widths, the individual parameters of the fitted Plummer functions are much more uncertain. The asymptotic power-law index has typically values p~3 but with a large scatter. Modelling shows that the FIR observations can systematically overestimate the filament widths. The effect is potentially tens of per cent at column densities above N(H$_2$) ~ $10^{22}$ cm$^{-2}$ but is reduced in more intense radiation fields, such as the Orion region. Spatial variations in dust properties could cause errors of similar magnitude. In the MIR analysis, dust scattering should generally not be a significant factor, unless there are high-mass stars nearby or the dust MIR scattering efficiency is higher than in the tested dust models. Thermal MIR dust emission can be a more significant source of error, especially close to embedded sources. The analysis of interstellar filaments can be affected by several sources of systematic error, but mainly at high column densities and, in the case of FIR observations, in weak radiation fields. The widths of the OMC-3 filaments were consistent between the MIR and FIR analyses and did not reveal systematic dependence on the angular resolution of the observations.

description: Aims. Our aim is to derive a fast and accurate method for computing the gravitational potential of astrophysical objects with high contrasts in density, for which nested or adaptive meshes are required. Methods. We present an extension of the convolution method for computing the gravitational potential to the nested Cartesian grids. The method makes use of the convolution theorem to compute the gravitational potential using its integral form. Results. A comparison of our method with the iterative outside-in conjugate gradient and generalized minimal residual methods for solving the Poisson equation using nonspherically symmetric density configurations has shown a comparable performance in terms of the errors relative to the analytic solutions. However, the convolution method is characterized by several advantages and outperforms the considered iterative methods by factors 10--200 in terms of the runtime, especially when graphics processor units are utilized. The convolution method also shows an overall second-order convergence, except for the errors at the grid interfaces where the convergence is linear. Conclusions. High computational speed and ease in implementation can make the convolution method a preferred choice when using a large number of nested grids. The convolution method, however, becomes more computationally costly if the dipole moments of tightly spaced gravitating objects are to be considered at coarser grids.

description: Pulsar timing arrays (PTAs) are Galactic-scale gravitational wave (GW) detectors consisting of precisely-timed pulsars distributed across the sky. Within the decade, PTAs are expected to detect the nanohertz GWs emitted by close-separation supermassive black hole binaries (SMBHBs), thereby opening up the low frequency end of the GW spectrum for science. Individual SMBHBs which power active galactic nuclei are also promising multi-messenger sources; they may be identified via theoretically predicted electromagnetic (EM) signatures and be followed up by PTAs for GW observations. In this work, we study the detection and parameter estimation prospects of a PTA which targets EM-selected SMBHBs. Adopting a simulated Galactic millisecond pulsar population, we envisage three different pulsar timing campaigns which observe three mock sources at different sky locations. We find that an all-sky PTA which times the best pulsars is an optimal and feasible approach to observe EM-selected SMBHBs and measure their source parameters to high precision (i.e., comparable to or better than conventional EM measurements). We discuss the implications of our findings in the context of the future PTA experiment with the planned Deep Synoptic Array-2000 and the multi-messenger studies of SMBHBs such as the well-known binary candidate OJ 287.

description: Gravity-driven thick granular flows are relevant to many industrial and geophysical processes. In particular, it is important to know and understand the particle velocity distributions as we get deeper into the flow from the free surface. In this paper, we use dimensional analysis as a tool to reproduce the velocity profile experimentally reported for granular flows down a confined heap for the so-called flowing layer and the creep layer underneath: the grains velocity first decrease linearly from the free surface, and then exponentially.

description: We establish the connection between the Magellanic Clouds (MCs) and the dwarf galaxy candidates discovered in the Dark Energy Survey (DES) by building a dynamical model of the MC satellite populations, based on an extensive suite of tailor-made numerical simulations. Our model takes into account the response of the Galaxy to the MCs infall, the dynamical friction experienced by the MCs and the disruption of the MC satellites by their hosts. The simulation suite samples over the uncertainties in the MC's proper motions, the masses of the MW and the Clouds themselves and allows for flexibility in the intrinsic volume density distribution of the MC satellites. As a result, we can accurately reproduce the DES satellites' observed positions and kinematics. Assuming that Milky Way (MW) dwarfs follow the distribution of subhaloes in $Λ$CDM, we further demonstrate that, of 14 observed satellites, the MW halo contributes fewer than 4 (8) of these with 68% (95%) confidence and that 7 (12) DES dwarfs have probabilities greater than 0.7 (0.5) of belonging to the LMC. Marginalising over the entire suite, we constrain the total number of the Magellanic satellites at ~70, the mass of the LMC around $10^{11}M_\odot$ and show that the Clouds have likely endured only one Galactic pericentric passage so far. Finally, we give predictions for the line-of-sight velocities and the proper motions of the satellites discovered in the vicinity of the LMC.

description: Often the filters learned by Convolutional Neural Networks (CNNs) from different datasets appear similar. This is prominent in the first few layers. This similarity of filters is being exploited for the purposes of transfer learning and some studies have been made to analyse such transferability of features. This is also being used as an initialization technique for different tasks in the same dataset or for the same task in similar datasets. Off-the-shelf CNN features have capitalized on this idea to promote their networks as best transferable and most general and are used in a cavalier manner in day-to-day computer vision tasks. It is curious that while the filters learned by these CNNs are related to the atomic structures of the images from which they are learnt, all datasets learn similar looking low-level filters. With the understanding that a dataset that contains many such atomic structures learn general filters and are therefore useful to initialize other networks with, we propose a way to analyse and quantify generality among datasets from their accuracies on transferred filters. We applied this metric on several popular character recognition, natural image and a medical image dataset, and arrived at some interesting conclusions. On further experimentation we also discovered that particular classes in a dataset themselves are more general than others.

description: Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and covers a total area of 50 square degrees distributed over two fields. It primarily aims at investigating the large-scale structures of the Universe using the distribution of galaxy clusters and active galactic nuclei as tracers of the matter distribution. Aims. This article presents the XXL bright cluster sample, a subsample of 100 galaxy clusters selected from the full XXL catalogue by setting a lower limit of $3\times 10^{-14}\,\mathrm{erg \,s^{-1}cm^{-2}}$ on the source flux within a 1$^{\prime}$ aperture. Methods. The selection function was estimated using a mixture of Monte Carlo simulations and analytical recipes that closely reproduce the source selection process. An extensive spectroscopic follow-up provided redshifts for 97 of the 100 clusters. We derived accurate X-ray parameters for all the sources. Scaling relations were self-consistently derived from the same sample in other publications of the series. On this basis, we study the number density, luminosity function, and spatial distribution of the sample. Results. The bright cluster sample consists of systems with masses between $M_{500}=7\times 10^{13}$ and $3\times 10^{14} M_\odot$, mostly located between $z=0.1$ and 0.5. The observed sky density of clusters is slightly below the predictions from the WMAP9 model, and significantly below the predictions from the Planck 2015 cosmology. In general, within the current uncertainties of the cluster mass calibration, models with higher values of $σ_8$ and/or $Ω_m$ appear more difficult to accommodate. We provide tight constraints on the cluster differential luminosity function and find no hint of evolution out to $z\sim1$. We also find strong evidence for the presence of large-scale structures in the XXL bright cluster sample and identify five new superclusters.
