description: Electronic screening renormalizes the linear bands of graphene and in the vicinity of the Dirac point, creates a diamond shaped structure in the quasiparticle spectral density. This is a result of electron-plasmon scattering processes which produce a finite momentum feature referred to as the `plasmaron ring'. In this work we explore the effects of uniaxial strain on these spectral features with the aim of understanding how strain modifies correlations. We derive and calculate the spectral density to the G$_0$W-RPA level which allows us to identify the dispersive behaviour of the diamond geometry, and thus electron-plasmon scattering, for variation in electron-electron coupling strength and magnitude of applied strain. We find that the application of strain changes the geometry (in momentum) of the electron-plasmon scattering and that renormalizations beyond simple geometrical scalings further enhance this effect. These results suggest that the properties of the plasmaron ring can be tuned through the application of uniaxial strain, effectively producing a larger fine structure constant without the need to change the sample substrate.

description: As the use of biometrics becomes more wide-spread, the privacy concerns that stem from the use of biometrics are becoming more apparent. As the usage of mobile devices grows, so does the desire to implement biometric identification into such devices. A large majority of mobile devices being used are mobile phones. While work is being done to implement different types of biometrics into mobile phones, such as photo based biometrics, voice is a more natural choice. The idea of voice as a biometric identifier has been around a long time. One of the major concerns with using voice as an identifier is the instability of voice. We have developed a protocol that addresses those instabilities and preserves privacy. This paper describes a novel protocol that allows a user to authenticate using voice on a mobile/remote device without compromising their privacy. We first discuss the \vv protocol, which has recently been introduced in research literature, and then describe its limitations. We then introduce a novel adaptation and extension of the vaulted verification protocol to voice, dubbed $V^3$. Following that we show a performance evaluation and then conclude with a discussion of security and future work.

description: In 2022, Venezuela’s deep political and governance crisis continued without a suitable constitutional and political solution. The situation worsened in some respects, given Maduro’s de facto consolidation of power and his ability to maintain control of the state apparatus. Consequently, there is a complex humanitarian emergency driving more than seven million Venezuelan migrants and refugees to seek refuge abroad. Currently, the Venezuelan migrant crisis is the second worst migrant crisis in the world, behind the Syrian migrant crisis. Moreover, despite a decrease in inflation and reports of slightly rising economic growth, the country remains mired in a deep state of corruption, without a reasonable economic plan backed by legal guarantees or a system based on the rule of law. The Maduro Government still faces international economic sanctions, refusing to engage in meaningful efforts to facilitate the return to a democratic constitutional government and continuing to disregard the 1999 Constitutional order. Not surprisingly, in 2022, Venezuela ranked 177/180 in the Corruption Perception Index and obtained the lowest world rank 140/140 in the Global Rule of Law Index.
On the surplus management of funds with assets and liabilities in presence of solvency requirements

description: In this paper we consider a company whose assets and liabilities evolve according to a correlated bivariate geometric Brownian motion, such as in Gerber and Shiu (2003). We determine what dividend strategy maximises the expected present value of dividends until ruin in two cases: (i) when shareholders won't cover surplus shortfalls and a solvency constraint (as in Paulsen, 2003) is consequently imposed, and (ii) when shareholders are always to fund any capital deficiency with capital (asset) injections. In the latter case, ruin will never occur and the objective is to maximise the difference between dividends and capital injections. Developing and using appropriate verification lemmas, we show that the optimal dividend strategy is, in both cases, of barrier type. Both value functions are derived in closed form. Furthermore, the barrier is defined on the ratio of assets to liabilities, which mimics some of the dividend strategies that can be observed in practice by insurance companies. Existence and uniqueness of the optimal strategies are shown. Results are illustrated.
Studying cosmic ray sources using intergalactic electromagnetic cascades

description: In this paper intergalatic electromagnetic cascades are used as a probe of cosmic ray sources. This is achieved as follows. In extragalactic space cosmic rays initiate electromagnetic cascades in which gamma-ray and neutrino emission arises. We used the joint analysis of cosmic ray data, along with extragalactic gamma-ray and neutrino emission, to study particle acceleration in the vicinity of supermassive black holes. Particle injection spectra depend on processes of particle acceleration, and here we discuss models with various injection spectra. The computation of the propagation of cosmic rays in space were performed using the publicly avaliable TransportCR code. It was found that a new subclass of sources might exist that does not contribute to the particle flux on Earth, instead to gamma-ray and neutrino emissions arising in electromagnetic cascades. In addition, the upper limit of the relative number of 'exotic' supermassive black holes surrounded by a superstrong magnetic field is derived.

description: Reinforcement learning (RL) agents learn to perform a task through trial-and-error interactions with an initially unknown environment. Despite the recent progress in deep RL, it remains a challenge to train intelligent agents that can efficiently explore a large state space and quickly solve a wide variety of tasks. One of the biggest obstacles is the high cost of human supervision for RL: it is difficult to design reward functions that provide enough learning signal yet still induce the correct behavior at convergence. To reduce the amount of human supervision required, there has been recent progress on self-supervised RL approaches, where the agent learns on its own by interacting with the environment without an extrinsic reward function. However, without any prior knowledge about the task, these methods can be sample-inefficient and suffer from poor exploration. Towards solving these challenges, this thesis focuses on how we can balance self-supervised RL with scalable forms of human supervision to efficiently train an agent for solving various high-dimensional robotic tasks. Being mindful about the cost of human labor required, we consider alternative modalities of supervision that can be more scalable and easier to provide from the human user. We show that such supervision can drastically improve the agent’s learning efficiency, enabling the agent to do directed exploration and learning within a large search space of states.

description: The large variability in experimentally measured mechanical properties of brain tissue is due to many factors including heterogeneity, anisotropy, age dependence and post-mortem time. Moreover, differences in test protocols also influence these measured properties. This paper shows that the temperature at which porcine brain tissue is stored or preserved prior to testing has a significant effect on the mechanical properties of brain tissue, even when tests are conducted at the same temperatures. Three groups of brain tissue were stored separately for at least one hour at three different preservation temperatures, i.e., ice cold, room temperature (22C) and body temperature (37C), prior to them all being tested at room temperature (approx. 22C). Significant differences in the corresponding initial elastic shear modulus mu (Pa) (at various amounts of shear, K, i.e., 0-0.2) were observed. The initial elastic moduli were 1043 +/- 271 Pa, 714 +/- 210 Pa and 497 +/- 156 Pa (mean +/- SD) at preservation temperatures of ice cold, 22C and 37C, respectively. Based on this investigation, it is strongly recommended that brain tissue samples must be preserved at an ice-cold temperature prior to testing in order to minimize the difference between the measured in vitro test results and the in vivo properties. A by-product of the study is that simple shear tests allow for large, almost perfectly homogeneous deformation of brain matter.

description: We study the cosmological effect of the simple scalar-torsion ($0^+$) mode in Poincaré gauge theory of gravity. We find that for the non-constant (affine) curvature case, the early evolution of the torsion density $ρ_T$ has a radiation-like asymptotic behavior of $a^{-4}$ with $a$ representing the scale factor, along with the stable point of the torsion pressure ($P_T$) and density ratio $P_T/ρ_T\rightarrow 1/3$ in the high redshift regime $(z \gg 0)$, which is different from the previous result in the literature. We use the Laurent expansion to resolve the solution. We also illustrate our result by the execution of numerical computations.

description: We report the measurement of first (\textit {n} = 1) and higher order(\textit{n} = 2-5) harmonic coefficients ($v_{n}$) of the azimuthal anisotropy in the distribution of the particles produced in U+U collisions at $\sqrt{s_{NN}}$ =193 GeV, recorded with the STAR detector at RHIC. The differential measurement of $(v_{n})$ is presented as a function of transverse momentum ($p_{T}$) and centrality. We also present $v_{n}$ measurement in the ultra-central collisions. These data may provide strong constraints on the theoretical models of the initial condition in heavy ion collisions and the transport properties of the produced medium.

Eruption of a plasma blob, associated M-class flare, and large-scale EUV wave observed by SDO

description: We present a multiwavelength study of the formation and ejection of a plasma blob and associated EUV waves in AR NOAA 11176, observed by SDO/AIA and STEREO on 25 March 2011. SDO/AIA images clearly show the formation and ejection of a plasma blob from the lower solar atmosphere at ~9 min prior to the onset of the M1.0 flare. This onset of the M-class flare happened at the site of the blob formation, while the blob was rising in a parabolic path with an average speed of ~300 km/s. The blob also showed twisting and de-twisting motion in the lower corona, and the blob speed varied from ~10-540 km/s. The faster and slower EUV wavefronts were observed in front of the plasma blob during its impulsive acceleration phase. The faster EUV wave propagated with a speed of ~785 to 1020 km/s, whereas the slower wavefront speed varied in between ~245 and 465 km/s. The timing and speed of the faster wave match the shock speed estimated from the drift rate of the associated type II radio burst. The faster wave experiences a reflection by the nearby AR NOAA 11177. In addition, secondary waves were observed (only in the 171 Åchannel), when the primary fast wave and plasma blob impacted the funnel-shaped coronal loops. The HMI magnetograms revealed the continuous emergence of new magnetic flux along with shear flows at the site of the blob formation. It is inferred that the emergence of twisted magnetic fields in the form of arch-filaments/"anemone-type" loops is the likely cause for the plasma blob formation and associated eruption along with the triggering of M-class flare. Furthermore, the faster EUV wave formed ahead of the blob shows the signature of fast-mode MHD wave, whereas the slower wave seems to be generated by the field line compression by the plasma blob. The secondary wave trains originated from the funnel-shaped loops are probably the fast magnetoacoustic waves.

description: Intensity fluctuations in supercontinuum generation are studied in polarization-maintaining (PM) and non-PM all-normal dispersion tellurite photonic crystal fibers. Dispersive Fourier transformation is used to resolve the shot-to-shot spectra generated using 225 fs pump pulses at 1.55 μm, with experimental results well reproduced by vector and scalar numerical simulations. By comparing the relative intensity noise for the PM and non-PM cases, supported by simulations, we demonstrate the advantage of the polarization-maintaining property of the PM fibers in preserving low-noise dynamics. We associate the low-noise in the PM case with the suppression of polarization modulation instability.

description: Several major innovations in artificial intelligence (AI) (e.g. convolutional neural networks, experience replay) are based on findings about the brain. However, the underlying brain findings took many years to first consolidate and many more to transfer to AI. Moreover, these findings were made using invasive methods in non human species. For brain functions that are uniquely human, such as understanding complex language, there is no suitable animal that can serve as a model organism and thus a mechanistic understanding is that much farther away. In this dissertation, we present a data-driven framework that circumvents these limitations by establishing a direct connection between brain recordings of people comprehending language and natural language processing (NLP) computer systems. We present evidence that this connection can be beneficial for both neurolinguistics and NLP. Specifically, we show that this framework can utilize recent successes in neural networks for NLP to enable scientific discovery about context- and task-dependent meaning composition in the brain, and we present the first evidence that brain activity measurements of people reading can be used to improve the generalization performance of a popular deep neural network language model. These investigations also contribute advances in cognitive modeling that may be useful beyond the study of language. In short, this dissertation involves multidisciplinary investigations and makes contributions to cognitive neuroscience, neurolinguistics, and natural language processing.

description: In this paper we introduce the `redshift fluctuation' as a gauge-invariant cosmological observable and give its fully relativistic expression at first order in cosmological perturbation theory. We show that this corresponds effectively to number counts with a radial window function with vanishing mean which therefore resolve smaller scale radial modes than standard number counts. In a detailed analysis of the angular power spectrum of this new variable, we study the relevance of different relativistic contributions, and how it differs from the conventional observable galaxy number count fluctuations. In order to investigate its utility for future spectroscopic surveys, we perform Fisher forecasts for a Euclid-like and an SKAII-like configuration, as examples. Particular focus is placed on the dependence of the results on the size of the redshift bins and on the cutoff in $\ell$ adopted in the analysis.

description: An incidence of a graph $G$ is a pair $(v,e)$ where $v$ is a vertex of $G$ and $e$ an edge incident to $v$. Two incidences $(v,e)$ and $(w,f)$ are adjacent whenever $v = w$, or $e = f$, or $vw = e$ or $f$. The incidence coloring game [S.D. Andres, The incidence game chromatic number, Discrete Appl. Math. 157 (2009), 1980-1987] is a variation of the ordinary coloring game where the two players, Alice and Bob, alternately color the incidences of a graph, using a given number of colors, in such a way that adjacent incidences get distinct colors. If the whole graph is colored then Alice wins the game otherwise Bob wins the game. The incidence game chromatic number $i_g(G)$ of a graph $G$ is the minimum number of colors for which Alice has a winning strategy when playing the incidence coloring game on $G$. Andres proved that %$\lceil 3/2 Δ(G)\rceil \le $i_g(G) \le 2Δ(G) + 4k - 2$ for every $k$-degenerate graph $G$. %The arboricity $a(G)$ of a graph $G$ is the minimum number of forests into which its set of edges can be partitioned. %If $G$ is $k$-degenerate, then $a(G) \le k \le 2a(G) - 1$. We show in this paper that $i_g(G) \le \lfloor\frac{3Δ(G) - a(G)}{2}\rfloor + 8a(G) - 2$ for every graph $G$, where $a(G)$ stands for the arboricity of $G$, thus improving the bound given by Andres since $a(G) \le k$ for every $k$-degenerate graph $G$. Since there exists graphs with $i_g(G) \ge \lceil\frac{3Δ(G)}{2}\rceil$, the multiplicative constant of our bound is best possible.

description: Hydrogen is a low carbon technology that can be utilized recently for gas fired power plants with a potential capacity of about 14.3 GW but has a very low energy density and hard and expensive to store and move around Some technical issues for Gas Turbine performance, not all existing gas fired power plants are ready for H2 co-firing. However, a ratio of 20% H2 co-firing for the most recent gas fired power plants are feasible without significant modification Today, making H2 from Renewables is expensive. To be financially feasible its price should be less than the gas price ($ 6/MMBTU) or the H2 production cost has to be below $ 0.68/kg and ammonia $ 0.11/kg Renewable Energy supply for producing H2 is limited. PLN, join with some international agencies, has issued REC of some RE resources for its both residential and industrial customers. The Government of Indonesia will add some new RE up to 10.64 GW until 2025. Green H2 prices are set to fall, it is expected to break-even by 2030 globally, but high Gas prices might bring parity earlier. In Indonesia the competitiveness of H2 can be achieved in 2038 within the Carbon tax policy

description: It has been generally believed that the multiple-input multiple-output (MIMO) channel capacity grows linearly with the size of antenna arrays. In terms of degrees of freedom, linear transmit and receive arrays of length $L$ in a scattering environment of total angular spread $|Ω|$ asymptotically have $|Ω| L$ degrees of freedom. In this paper, it is claimed that the linear increase in degrees of freedom may not be attained when scattered electromagnetic fields in the underlying scattering environment are statistically correlated. After introducing a model of correlated scattering, which is referred to as the colored scattering model, we derive the number of degrees of freedom. Unlike the uncorrelated case, the number of degrees of freedom in the colored scattering channel is asymptotically limited by $|Ω| \cdot \min \{L, 1/Γ}$, where $Γ$ is a parameter determining the extent of correlation. In other words, for very large arrays in the colored scattering environment, degrees of freedom can get saturated to an intrinsic limit rather than increasing linearly with the array size.

description: Type 2 diabetes mellitus (T2DM) and impaired kidney function are associated with a higher risk of poor outcomes of coronavirus disease 2019 (COVID-19). We conducted a retrospective study in hospitalized T2DM patients with COVID-19 to assess the association between in-hospital mortality and admission values of different hematological/biochemical parameters, including estimated glomerular filtration rate (eGFR), plasma glucose and C-peptide (the latter serving as a marker of beta-cell function). The study included T2DM patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection who were consecutively admitted to our Institution between 1 October 2020 and 1 April 2021. Patients (n = 74) were categorized into survivors (n = 55) and non-survivors (n = 19). Non-survivors exhibited significantly higher median white blood cell (WBC) count, D-dimer, neutrophil-to-lymphocyte ratio, high-sensitivity C-reactive protein (hsCRP), and procalcitonin levels, as well as significantly lower median serum 25-hydroxyvitamin D [25(OH)D] levels compared to survivors. Non-survivors exhibited significantly higher median admission plasma glucose (APG) values compared to survivors (210 vs. 166 mg/dL; p = .026). There was no statistically significant difference in median values of (random) plasma C-peptide between non-survivors and survivors (3.55 vs. 3.24 ng/mL; p = .906). A significantly higher percentage of patients with an eGFR < 60 mL/min/1.73 m2 was observed in the non-survivor group as compared to the survivor group (57.9% vs. 23.6%; p = .006). A multivariate analysis performed by a logistic regression model after adjusting for major confounders (age, sex, body mass index, major comorbidities) showed a significant inverse association between admission eGFR values and risk of in-hospital mortality (OR, 0.956; 95% CI, 0.931-0.983; p = .001). We also found a significant positive association between admission WBC count and risk of in-hospital mortality (OR, 1.210; 95% CI, 1.043–1.404; p = .011). Admission eGFR and WBC count predict in-hospital COVID-19 mortality among T2DM patients, independently of traditional risk factors, APG and random plasma C-peptide. Hospitalized patients with COVID-19 and comorbid T2DM associated with impaired kidney function at admission should be considered at high risk for adverse outcomes and death.

description: Andreev-Bashkin drag plays a very important role in multiple areas like superfluid mixtures, superconductors and dense nuclear matter. Here, we point out that the drag phenomenon can be also important in physics of solitons, ubiquitous objects arising in a wide array of fields ranging from tsunami waves and fiber-optic communication to biological systems. So far, fruitful studies were conducted in ultracold atomic systems where nontrivial soliton dynamics occurred due to inter-component density-density interaction. In this work we show that current-current coupling between components (Andreev-Bashkin drag) can lead to a substantially different kind of effects, unsupported by density-density interactions, such as a drag-induced dark soliton generation. This also points out that soliton dynamics can be used as a tool to experimentally study the dissipationless drag effect.

description: This study examines the relationships between changes in antipsychotic medication (AP) use and acute clinical events (identified with administrative claims data) for patients with FDA-approved indications for APs following transition from the community (e.g. home) to a nursing home (NH) in a Medicare population. A retrospective analysis was conducted using 100% Medicare fee-for-service (FFS) research identifiable files (RIF) claims data (2016–2018). Medicare beneficiaries with a condition for which APs are approved by the FDA were examined using logistic regression models to determine whether changes in AP use following transition from community to NHs were correlated with the likelihood of experiencing acute clinical events. We identified 38,448 Medicare FFS beneficiaries meeting our study criteria. A change in AP use after transition to a NH did not have a statistically significant association with acute skeletal events, coronary artery events, or cerebrovascular events (p = .55, p = .69, and p = .59, respectively). Between 2016 and 2018, Medicare FFS patients with approved-use indications for APs had lower average AP use following transition to a NH. Changes in the use of other medications of interest largely followed a similar pattern, indicating that these medications did not tend to be used as substitutions for APs. No clear relationship exists between increases or decreases in AP use and adverse events among NH residents who used APs and had FDA-approved conditions in the community setting.

description: Memory system is often the main bottleneck in chipmultiprocessor (CMP) systems in terms of latency, bandwidth and efficiency, and recently additionally facing capacity and power problems in an era of big data. A lot of research works have been done to address part of these problems, such as photonics technology for bandwidth, 3D stacking for capacity, and NVM for power as well as many micro-architecture level innovations. Many of them need a modification of current memory architecture, since the decades-old synchronous memory architecture (SDRAM) has become an obstacle to adopt those advances. However, to the best of our knowledge, none of them is able to provide a universal memory interface that is scalable enough to cover all these problems. In this paper, we argue that a message-based interface should be adopted to replace the traditional bus-based interface in memory system. A novel message interface based memory system (MIMS) is proposed. The key innovation of MIMS is that processor and memory system communicate through a universal and flexible message interface. Each message packet could contain multiple memory requests or commands along with various semantic information. The memory system is more intelligent and active by equipping with a local buffer scheduler, which is responsible to process packet, schedule memory requests, and execute specific commands with the help of semantic information. The experimental results by simulator show that, with accurate granularity message, the MIMS would improve performance by 53.21%, while reducing energy delay product (EDP) by 55.90%, the effective bandwidth utilization is improving by 62.42%. Furthermore, combining multiple requests in a packet would reduce link overhead and provide opportunity for address compression.

description: Two-dimensional (2D) semiconductor of MoS2 has great potential for advanced electronics technologies beyond silicon1-9. So far, high-quality monolayer MoS2 wafers10-12 are already available and various demonstrations from individual transistors to integrated circuits have also been shown13-15. In addition to the monolayer, multilayers have narrower band gaps but improved carrier mobilities and current capacities over the monolayer5,16-18. However, achieving high-quality multilayer MoS2 wafers remains a challenge. Here we report the growth of high quality multilayer MoS2 4-inch wafers via the layer-by-layer epitaxy process. The epitaxy leads to well-defined stacking orders between adjacent epitaxial layers and offers a delicate control of layer numbers up to 6. Systematic evaluations on the atomic structures and electronic properties were carried out for achieved wafers with different layer numbers. Significant improvements on device performances were found in thicker-layer field effect transistors (FETs), as expected. For example, the average field-effect mobility (μFE) at room temperature (RT) can increase from ~80 cm2V-1s-1 for monolayer to ~110/145 cm2V-1s-1 for bilayer/trilayer devices. The highest RT μFE=234.7 cm2V-1s-1 and a record-high on-current densities of 1.704 mAμm-1 at Vds=2 V were also achieved in trilayer MoS2 FETs with a high on/off ratio exceeding 107. Our work hence moves a step closer to practical applications of 2D MoS2 in electronics.

description: The red ghost crab (Ocypode macrocera) is considered a bioturbator, an environmental architect, a geochemical engineer, a biological engineer, a physical engineer and a climate engineer. Lalkakrar Char (Shoal of red crab) is the paradise habitat of red ghost crabs in Bangladesh. In the near past, thousands of crabs came out of the holes and the shoal turned into the red island of scenic beauty during low tide. It is reported that the abundance of red crabs is declining in this area. The study aims to identify the threats to conservation and find out solutions. It was found that motorcycles and mechanized vans for carrying tourists destroy the residing hole of the little mermaid. Consequently, the red crabs are often found injured or dead on the beach. Resultantly, the oxygenation, organic matter decomposition and bioturbation on the beach soil are highly affected. The exotic high water-consuming trees cause scarcity of groundwater, which in turn, leads to the dryness of the shoal gradually. Incremental pollution accelerates eutrophication, turbidity, and hypoxia. As a result, the abundance of dead jellyfish shows an uptrend. The escalated trend of trash and plastic bottles chokes the penetration of the crab community. The study advocated some conservation activities.
