description: BACKGROUND AND AIMS: Treatment with tumor necrosis factor α (TNFα) antagonists in IBD patients suffers from primary non-response rates of up to 40%. Biomarkers for early prediction of therapy success are missing. We investigated the dynamics of gene expression and DNA methylation in blood samples of IBD patients treated with the TNF antagonist infliximab and analyzed the predictive potential regarding therapy outcome. METHODS: We performed a longitudinal, blood-based multi-omics study in two prospective IBD patient cohorts receiving first-time infliximab therapy (discovery: 14 patients, replication: 23 patients). Samples were collected at up to 7 time points (from baseline to 14 weeks after therapy induction). RNA-sequencing and genome-wide DNA methylation data were analyzed and correlated with clinical remission at week 14 as a primary endpoint. RESULTS: We found no consistent ex ante predictive signature across the two cohorts. Longitudinally upregulated transcripts in the non-remitter group comprised TH2- and eosinophil-related genes including ALOX15, FCER1A, and OLIG2. Network construction identified transcript modules that were coherently expressed at baseline and in non-remitting patients but were disrupted at early time points in remitting patients. These modules reflected processes such as interferon signaling, erythropoiesis, and platelet aggregation. DNA methylation analysis identified remission-specific temporal changes, which partially overlapped with transcriptomic signals. Machine learning approaches identified features from differentially expressed genes cis-linked to DNA methylation changes at week 2 as a robust predictor of therapy outcome at week 14, which was validated in a publicly available dataset of 20 infliximab-treated CD patients. CONCLUSIONS: Integrative multi-omics analysis reveals early shifts of gene expression and DNA methylation as predictors for efficient response to anti-TNF treatment. Lack of such signatures might be used to identify patients with IBD unlikely to benefit from TNF antagonists at an early time point.

description: We construct numerically finite density domain-wall solutions which interpolate between two $AdS_4$ fixed points and exhibit an intermediate regime of hyperscaling violation, with or without Lifshitz scaling. Such RG flows can be realized in gravitational models containing a dilatonic scalar and a massive vector field with appropriate choices of the scalar potential and couplings. The infrared $AdS_4$ fixed point describes a new ground state for strongly coupled quantum systems realizing such scalings, thus avoiding the well-known extensive zero temperature entropy associated with $AdS_2 \times \mathbb{R}^2$. We also examine the zero temperature behavior of the optical conductivity in these backgrounds and identify two scaling regimes before the UV CFT scaling is reached. The scaling of the conductivity is controlled by the emergent IR conformal symmetry at very low frequencies, and by the intermediate scaling regime at higher frequencies.

description: In Saccharomyces cerevisiae, the transcriptional repressor Nrg1 (Negative Regulator of Glucose-repressed genes) and the β-Zip transcription factor Rtg3 (ReTroGrade regulation) mediate glucose repression and signalling from the mitochondria to the nucleus, respectively. Here, we show a novel function of these two proteins, in which alanine promotes the formation of a chimeric Nrg1/Rtg3 regulator that represses the ALT2 gene (encoding an alanine transaminase paralog of unknown function). An NRG1/NRG2 paralogous pair, resulting from a post-wide genome small-scale duplication event, is present in the Saccharomyces genus. Neo-functionalization of only one paralog resulted in the ability of Nrg1 to interact with Rtg3. Both nrg1Δ and rtg3Δ single mutant strains were unable to use ethanol and showed a typical petite (small) phenotype on glucose. Neither of the wild-type genes complemented the petite phenotype, suggesting irreversible mitochondrial DNA damage in these mutants. Neither nrg1Δ nor rtg3Δ mutant strains expressed genes encoded by any of the five polycistronic units transcribed from mitochondrial DNA in S. cerevisiae. This, and the direct measurement of the mitochondrial DNA gene complement, confirmed that irreversible damage of the mitochondrial DNA occurred in both mutant strains, which is consistent with the essential role of the chimeric Nrg1/Rtg3 regulator in mitochondrial DNA maintenance.

description: Motivated by recent pump-probe spectroscopies, we study the effect of phonon dissipation and potential cooling on the nonequilibrium distribution function in a Floquet topological state. To this end, we apply a Floquet kinetic equation approach to study two dimensional Dirac fermions irradiated by a circularly polarized laser, a system which is predicted to be in a laser induced quantum Hall state. We find that the initial electron distribution shows an anisotropy with momentum dependent spin textures whose properties are controlled by the switching-on protocol of the laser. The phonons then smoothen this out leading to a non-trivial isotropic nonequilibrium distribution which has no memory of the initial state and initial switch-on protocol, and yet is distinct from a thermal state. An analytical expression for the distribution at the Dirac point is obtained that is relevant for observing quantized transport.

description: Over the Texas-Louisiana Shelf in the Northern Gulf of Mexico, the eutrophic, fresh Mississippi/Atchafalaya river plume isolates saltier waters below, supporting the formation of bottom hypoxia in summer. The plume also generates strong density fronts, features of the circulation that are known pathways for the exchange of water between the ocean surface and the deep. Using high-resolution ocean observations and numerical simulations, we demonstrate how the summer land-sea breeze generates rapid vertical exchange at the plume fronts. We show that the interaction between the land-sea breeze and the fronts leads to convergence/divergence in the surface mixed layer, which further facilitates a slantwise circulation that subducts surface water along isopycnals into the interior and upwells bottom waters to the surface. This process causes significant vertical displacements of water parcels and creates a ventilation pathway for the bottom water in the northern Gulf. The ventilation of bottom water can bypass the stratification barrier associated with the Mississippi/Atchafalaya river plume and might impact the dynamics of the region's dead zone.

description: The phonon Hall effect has been observed in the paramagnetic insulator, Tb3Gd5O12. A magnetic field applied perpendicularly to a heat current induces a temperature gradient that is perpendicular to both the field and the current. We show that this effect is due to resonant skew scattering of phonons from the crystal field states of superstoichiometric Tb^3+ ions. This scattering originates from the coupling between the quadrupole moment of Tb^3+ ions and the lattice strain. The estimated magnitude of the effect is consistent with experimental observations at T=5 K, and can be significantly enhanced by increasing temperature.

description: Developmental language disorder (DLD) is a common neurodevelopmental disorder characterised by receptive or expressive language difficulties or both. While theoretical frameworks and empirical studies support the idea that there may be neural correlates of DLD in frontostriatal loops, findings are inconsistent across studies. Here, we use a novel semiquantitative imaging protocol - multi-parameter mapping (MPM) - to investigate microstructural neural differences in children with DLD. The MPM protocol allows us to reproducibly map specific indices of tissue microstructure. In 56 typically developing children and 33 children with DLD, we derived maps of (1) longitudinal relaxation rate R1 (1/T1), (2) transverse relaxation rate R2* (1/T2*), and (3) Magnetization Transfer saturation (MTsat). R1 and MTsat predominantly index myelin, while R2* is sensitive to iron content. Children with DLD showed reductions in MTsat values in the caudate nucleus bilaterally, as well as in the left ventral sensorimotor cortex and Heschl's gyrus. They also had globally lower R1 values. No group differences were noted in R2* maps. Differences in MTsat and R1 were coincident in the caudate nucleus bilaterally. These findings support our hypothesis of corticostriatal abnormalities in DLD and indicate abnormal levels of myelin in the dorsal striatum in children with DLD.

Ein kaum beachteter Stimmensatz aus den Beständen der Singakademie zu Berlin (Palestrina, 'Missa Ecce sacerdos magnus'; D-Bsak SA 424, geschrieben von Johann Christoph Altnickol und Bach) dokumentiert, dass Bach in den 1740er Jahren die Aufführungen mehrerer Palestrina-Messen andachte. Eine bisher unbekannte Partitur mit einzelnen Sätzen aus sechs Messen Palestrinas belegt, dass Bach sich nicht erst am Ende seines Lebens mit Palestrina auseinander setzte, sondern ihn bereits in seinen Weimarer Jahren studierte.

description: This paper presents an introduction to phase transitions and critical phenomena on the one hand, and nonequilibrium patterns on the other, using the Ginzburg-Landau theory as a unified language. In the first part, mean-field theory is presented, for both statics and dynamics, and its validity tested self-consistently. As is well known, the mean-field approximation breaks down below four spatial dimensions, where it can be replaced by a scaling phenomenology. The Ginzburg-Landau formalism can then be used to justify the phenomenological theory using the renormalization group, which elucidates the physical and mathematical mechanism for universality. In the second part of the paper it is shown how near pattern forming linear instabilities of dynamical systems, a formally similar Ginzburg-Landau theory can be derived for nonequilibrium macroscopic phenomena. The real and complex Ginzburg-Landau equations thus obtained yield nontrivial solutions of the original dynamical system, valid near the linear instability. Examples of such solutions are plane waves, defects such as dislocations or spirals, and states of temporal or spatiotemporal (extensive) chaos.

description: Diese Arbeit beschäftigt sich mit der Thematik wie bestimmte Kontexte die Handlungsfähigkeit von Individuen einschränken können. Die Zielgruppe war aus diesem Grund eine Gruppe die einen sehr polarisierenden Handlungsspielraum hat: Frauen mit Migrationshintergrund die sich haben in MINT ausbilden lassen. Dadurch das der aktuelle Arbeitsmarkt in Österreich vor allem im technischen Bereich einen enormen Mangel, vor allem an weiblichem Personal, aufzeigt und der berufliche Horizont allgemein mit einer alternden Gesellschaft konfrontiert ist müsste diese Gruppe sehr viel Handlungsmacht haben Aufgrund von der enormen Nachfrage, die besteht. Der Fokus lag auf der Selbstwahrnehmung der eigenen Agency welche mithilfe von problemzentrierten Interviews erhoben worden ist. Die Ergebnisse der Feinstruktur- und der sie komplementierenden Systemanalyse zeigen auf, dass obgleich der Arbeitsmarkt solch einen enormen Bedarf sowohl an Frauen als auch an Migrant*innen hat, genau diese strukturellen Gegebenheiten es sind die die betroffenen Personen in ihrer beruflichen Laufbahn am stärksten einschränken.
description: This thesis focuses on the point, that certain contexts limit the agency of individuals. The focus group was for that very reason one that has a very polarizing position on the autrian job market: Women with non-European citizenships that have a STEM-based education. Since currently the Austrian job market is lacking in technically skilled workers, especially females, and the general population is getting progressively older, this group should have enormous power and value. Therefore, the focal point was the self-perception of agency which was explored through problem-centered interviews. The result of the extensive analysis showcases, that even though there is such a need for women and migrants on the job market it is mostly these factors that limit them the most.

description: The spectrum of random ergodic Schrödinger-type operators is almost surely a deterministic subset of the real line. The random operator can be considered as a perturbation of a periodic one. As soon as the disorder is switched on via a global coupling constant, the spectrum expands. We estimate how much the spectrum expands at its bottom for operators on $\ell^2(\mathbb Z^d)$.

description: In the development of highly efficient photovoltaic cells, solid perovskite systems have demonstrated unprecedented promise, with the figure of merit exceeding nineteen percent of efficiency. In this paper, we investigate the optical and vibrational properties of organometallic cubic perovskite CH3NH3PbI3 using first-principles calculations. For accurate theoretical description, we go beyond conventional density functional theory (DFT), and calculated optical conductivity using relativist quasi-particle (GW) correction. Incorporating these many-body effects, we further solve Bethe-Salpeter equations (BSE) for excitons, and found enhanced optical conductivity near the gap edge. Due to the presence of organic methylammonium cations near the center of the perovskite cell, the system is sensitive to low energy vibrational modes. We estimate the phonon modes of CH3NH3PbI3 using small displacement approach, and further calculate the infrared absorption (IR) spectra. Qualitatively, our calculations of low-energy phonon frequencies are in good agreement with our terahertz measurements. Therefore, for both energy scales (around 2 eV and 0-20 meV), our calculations reveal the importance of many-body effects and their contributions to the desirable optical properties in the cubic organometallic perovskites system.

description: We present two different search methods for electromagnetic counterparts to gravitational-wave (GW) events from ground-based detectors using archival NASA high-energy data from the Fermi-GBM and RXTE-ASM instruments. To demonstrate the methods, we use a limited number of representative GW background noise events produced by a search for binary neutron star coalescence over the last two months of the LIGO-Virgo S6/VSR3 joint science run. Time and sky location provided by the GW data trigger a targeted search in the high-energy photon data. We use two custom pipelines: one to search for prompt gamma-ray counterparts in GBM, and the other to search for a variety of X-ray afterglow model signals in ASM. We measure the efficiency of the joint pipelines to weak gamma-ray burst counterparts, and a family of model X-ray afterglows. By requiring a detectable signal in either electromagnetic instrument coincident with a GW event, we are able to reject a large majority of GW candidates. This reduces the signal-to-noise of the loudest surviving GW background event by around 15-20%.

description: This paper is motivated by the need to improve the post-Newtonian (PN) amplitude accuracy of waveforms for gravitational waves generated by inspiralling compact binaries, both for use in data analysis and in the comparison between post-Newtonian approximations and numerical relativity computations. It presents: (i) the non-linear couplings between multipole moments of general post-Newtonian matter sources up to order 3.5PN, including all contributions from tails, tails-of-tails and the non-linear memory effect; and (ii) the source mass-type octupole moment of (non-spinning) compact binaries up to order 3PN, which permits to complete the expressions of the octupole modes (3,3) and (3,1) of the gravitational waveform to order 3.5PN. At this occasion we reconfirm by means of independent calculations our earlier results concerning the source mass-type quadrupole moment to order 3PN. Related discussions on factorized resummed waveforms and the occurence of logarithmic contributions to high order are also included.

description: Understanding the long-term impact that changes in a city's transportation infrastructure have on its spatial interactions remains a challenge. The difficulty arises from the fact that the real impact may not be revealed in static or aggregated mobility measures, as these are remarkably robust to perturbations. More generally, the lack of longitudinal, cross-sectional data demonstrating the evolution of spatial interactions at a meaningful urban scale also hinders us from evaluating the sensitivity of movement indicators, limiting our capacity to understand the evolution of urban mobility in depth. Using very large mobility records distributed over three years we quantify the impact of the completion of a metro line extension: the circle line (CCL) in Singapore. We find that the commonly used movement indicators are almost identical before and after the project was completed. However, in comparing the temporal community structure across years, we do observe significant differences in the spatial reorganization of the affected geographical areas. The completion of CCL enables travelers to re-identify their desired destinations collectively with lower transport cost, making the community structure more consistent. These changes in locality are dynamic, and characterized over short time-scales, offering us a different approach to identify and analyze the long-term impact of new infrastructures on cities and their evolution dynamics.

description: An understanding of density fluctuations in bulk water has made significant contributions to our understanding of the hydration and interactions of idealized, purely repulsive hydrophobic solutes. To similarly inform the hydration of realistic hydrophobic solutes that have dispersive interactions with water, here we characterize water density fluctuations in the presence of attractive fields that correspond to solute-water attractions. We find that when the attractive field acts only in the solute hydration shell, but not in the solute core, it does not significantly alter water density fluctuations in the solute core region. We further find that for a wide range of solute sizes and attraction strengths, the free energetics of turning on the attractive fields in bulk water are accurately captured by linear response theory. Our results also suggest strategies for more efficiently estimating hydration free energies of realistic solutes in bulk water and at interfaces.

title: Der Einfluss von Telearbeit auf die sozialen Interaktionen zwischen Arbeitnehmern und Vorgesetzten unter Berücksichtigung von Reziprozität
Creators: name: Döhring, Moritz Laurens
Year: 2021

description: In der Arbeitswelt kommt es aufgrund des technischen Fortschritts sowie den sich ändernden Bedürfnissen der ArbeitnehmerInnen zu kontinuierlichen Veränderungen. Telearbeit ist eine Arbeitsform, die sich dadurch in den letzten Jahrzehnten entwickelt und verbreitet hat. Obwohl Telearbeit bereits seit seiner Einführung erforscht wird, erhielten die privaten sozialen Interaktionen unter Berücksichtigung von Reziprozität kaum Aufmerksamkeit. Das Ziel dieser Arbeit ist es daher, der zentralen Frage nachzugehen, ob Telearbeit einen Einfluss auf die privaten sozialen Interaktionen zwischen ArbeitnehmerInnen und Vorgesetzten unter Berücksichtigung von Reziprozität ausübt. Zu diesem Zweck wurden im Rahmen einer quantitativen Online-Befragung Daten von 63 vollzeitbeschäftigten ArbeitnehmerInnen erhoben, die anteilig an ihrer wöchentlichen Arbeitszeit Telearbeit nachgehen. Die deskriptive Auswertung kommt zu dem Ergebnis, dass die Intensität von Telearbeit zu einer Reduktion der privaten sozialen Interaktionen führen kann. Die explorative Datenanalyse konnte belegen, dass die Intensität von Telearbeit einen negativen Einfluss auf die Häufigkeit der privaten sozialen Interaktionen an Bürotagen zwischen ArbeitnehmerInnen und Vorgesetzten hat. Der vermutete Moderationseffekt durch die wahrgenommene Reziprozität auf diesen negativen Zusammenhang konnte statistisch nicht belegt werden. Diese Arbeit zeigt, dass die informellen Interaktionen zwischen ArbeitnehmerInnen und Vorgesetzten im Arbeitsalltag von Telearbeit beeinträchtigt sind.

description: The properties of the system must be inferred from the remnants of the collision which reach detectors a few meters away from the collision region. The non-interacting pieces of the Au nuclei continue forward in the beam direction after the collision, but in the collision region energy is scattered perpendicular to the beam direction. In this present work we are interested in the particles which are the remains of inelastic parton and the nucleon scattering of the collision. We investigate jet-like azimuthal correlations between two particles where one or both is identified at intermediate pT. Two particle correlations provide additional information hence one can discriminate between particle production mechanisms than single particle observables.

description: A Maple code is presented for algebraic collective model (ACM) calculations. The ACM is an algebraic version of the Bohr model of the atomic nucleus, in which all required matrix elements are derived by exploiting the model's SU(1,1) x SO(5) dynamical group. This paper reviews the mathematical formulation of the ACM, and serves as a manual for the code. The code enables a wide range of model Hamiltonians to be analysed. This range includes essentially all Hamiltonians that are rational functions of the model's quadrupole moments $q_M$ and are at most quadratic in the corresponding conjugate momenta $π_N$ ($-2\le M,N\le 2$). The code makes use of expressions for matrix elements derived elsewhere and newly derived matrix elements of the operators $[π\otimes q \otimesπ]_0$ and $[π\otimesπ]_{LM}$. The code is made efficient by use of an analytical expression for the needed SO(5)-reduced matrix elements, and use of SO(5)$\,\supset\,$SO(3) Clebsch-Gordan coefficients obtained from precomputed data files provided with the code.

description: In this paper we construct numerical schemes to approximate linear transport equations with slab geometry by diffusion equations. We treat both the case of pure diffusive scaling and the case where kinetic and diffusive scalings coexist. The diffusion equations and their data are derived from asymptotic and layer analysis which allows general scattering kernels and general data. We apply the half-space solver in [20] to resolve the boundary layer equation and obtain the boundary data for the diffusion equation. The algorithms are validated by numerical experiments and also by error analysis for the pure diffusive scaling case.

description: Abstract 
The rapid growth of online communication through social media, websites, blogs and other platforms has increased consumer awareness of electronic word of mouth. Consumers' desire for social contact, financial rewards, caring about other consumers, and the potential value of endorsements have all been highlighted as major motivators that affect how they behave when using electronic word-of-mouth. The main objective of the present study is to investigate consumer perceptions regarding the attributes of electronic word of mouth in Cuddalore district. The primary data for the study was collected using a multistage sampling technique. Five of the seven taluks of Cuddalore district have been selected for the first stage. For the second stage, convenience sampling was used to select 90 respondents from each taluk. A survey method was used to carry out this empirical investigation. The primary data, which forms a crucial part of the study, was collected from 450 respondents using the schedule method. The objectives of the study were taken into consideration when a schedule was developed using the Likert scale technique. 25 consumers participated in a pre-test of the schedule to assess the relevance of the questions. Considering the results of the pre-test, necessary changes were made to the revised schedule. Theses, journals, periodicals and unpublished publications were the secondary data sources. The top five attributes of electronic word of mouth, according to consumers, are that reviews and comments are up to date, that people can rely on EWOM to determine the effectiveness of a product, EWOM information about a product is convincing, the opinions and comments shared by others online are convincing, and the reviews and opinions shared online are reasonable. The study made recommendations on how to make electronic word of mouth more effective.

description: We analyze the possible effects arising from Planck scale regime upon the interference pattern of two non-interacting Bose-Einstein condensates. We start with the analysis of the free expansion of a condensate, taken into account the effects produced by a deformed dispersion relation, suggested in several quantum-gravity models. The analysis of the condensate free expansion, in particular, the modified free velocity expansion, suggests in a natural way, a modified uncertainty principle that could leads to new phenomenological implications related to the quantum structure of space time. Finally, we analyze the corresponding separation between the interference fringes after the two condensates overlap, in order to explore the sensitivity of the system to possible signals caused by the Planck scale regime.

description: Abstract
The advancement of AI-based ALGO-TRADE technology has prompted enterprises worldwide to adapt their operational strategies. This novel technological advancement empowers investors to increase their chances of success and reduce their reliance on luck. In certain situations, traders use the buy-or-write approach when they have only one remaining commodity. The research methodology employed here is the "buy-and-sell maximization study design," which generates subjective evaluations. In this study, we developed ALGO-TRADE programs using Stoller Average Range Channels (S.A.R.). In finance, S.A.R. is a technical indicator visually representing a trading range's upper and lower boundaries. It constructs price-bounding envelopes by drawing lines one standard deviation above and below a simple moving average of prices. The standard deviation utilization determines the Band's magnitude, making it responsive to market fluctuations. Employing S.A.R. assists in determining whether the current price significantly deviates from the expected range. Many individuals commonly use both upper and lower bands in conjunction with a moving average. Furthermore, their design intended for these bands to complement each other, and using them independently may compromise their functionality. It is essential to incorporate supplementary indicators that exhibit strong compatibility and thoroughly verify their findings. The investigation also analyzed the financial gains and losses the commodity trading account incurred during the fiscal years 2021 and 2022. According to the results, an individual who trades with an initial investment of Rs 1,00,000 has the potential to generate a profit of Rs 60,000.

description: In recent papers it has been demonstrated that sampling a Gibbs distribution from an appropriate time-irreversible Langevin process is, from several points of view, advantageous when compared to sampling from a time-reversible one. Adding an appropriate irreversible drift to the overdamped Langevin equation results in a larger large deviations rate function for the empirical measure of the process, a smaller variance for the long time average of observables of the process, as well as a larger spectral gap. In this work, we concentrate on irreversible Langevin samplers with a drift of increasing intensity. The asymptotic variance is monotonically decreasing with respect to the growth of the drift and we characterize its limiting behavior. For a Gibbs measure whose potential has one or more critical points, adding a large irreversible drift results in a decomposition of the process in a slow and fast component with fast motion along the level sets of the potential and slow motion in the orthogonal direction. This result helps understanding the variance reduction, which can be explained at the process level by the induced fast motion of the process along the level sets of the potential. The limit of the asymptotic variance as the magnitude of the irreversible perturbation grows is the asymptotic variance associated to the limiting slow motion. The latter is a diffusion process on a graph.

description: We investigate the dynamics of $2$-generator semigroups of polynomials with bounded planar postcritical set and associated random dynamics on the Riemann sphere. Also, we investigate the space ${\cal B}$ of such semigroups. We show that for a parameter $h$ in the intersection of ${\cal B}$, the hyperbolicity locus ${\cal H}$ and the closure of the disconnectedness locus (the space of parameters for which the Julia set is disconnected), the corresponding semigroup satisfies either the open set condition (and the Bowen's formula) or that the Julia sets of the two generators coincide. Also, we show that for such a parameter $h$, if the Julia sets of the two generators do not coincide, then there exists a neighborhood $U$ of $h$ in the full parameter space ${\cal P}^{2}$ such that for each parameter in $U$, the Hausdorff dimension of the Julia set of the corresponding semigroup is strictly less than 2. Moreover, we show that the intersection of the connectedness locus and ${\cal B}\cap {\cal H}$ has dense interior. By using the results on the semigroups corresponding to these parameters, we investigate the associated functions which give the probability of tending to $\infty$ (complex analogues of the devil's staircase or Lebesgue's singular functions) and complex analogues of the Takagi function.

title: Generalized Autoregressive Gamma Processes

description: We introduce generalized autoregressive gamma (GARG) processes, a class of autoregressive
and moving-average processes that extends the class of existing autoregressive gamma (ARG)
processes in one important dimension: each conditional moment dynamic is driven by a
different and identifiable moving average of the variable of interest. The paper provides
ergodicity conditions for GARG processes and derives closed-form conditional and
unconditional moments. The paper also presents estimation and inference methods, illustrated
by an application to European option pricing where the daily realized variance follows a GARG
dynamic. Our results show that using GARG processes reduces pricing errors by substantially
more than using ARG processes does.
description: Nous présentons les processus gamma autorégressifs généralisés (GARG), une catégorie de
processus autorégressifs et moyennes mobiles qui est un prolongement de la catégorie
existante de processus gamma autorégressifs dans une dimension importante : la dynamique
de chacun des moments conditionnels est influencée par une différente moyenne mobile
identifiable de la variable d’intérêt. Nous fournissons les conditions d’ergodicité pour les
processus GARG et en établissons les moments conditionnels et inconditionnels de forme
fermée. Nous présentons aussi des méthodes d’estimation et d’inférence, puis les appliquons
à l’évaluation d’options européennes où la variance quotidienne réalisée suit la dynamique des
processus GARG. Nos résultats montrent que l’utilisation de ces processus réduit les erreurs
d’évaluation de façon nettement plus importante que les processus gamma autorégressifs.

description: Phosphorene, the single layer counterpart of black phosphorus, is a novel two-dimensional semiconductor with high carrier mobility and a large fundamental direct band gap, which has attracted tremendous interest recently. Its potential applications in nano-electronics and thermoelectrics call for a fundamental study of the phonon transport. Here, we calculate the intrinsic lattice thermal conductivity of phosphorene by solving the phonon Boltzmann transport equation (BTE) based on first-principles calculations. The thermal conductivity of phosphorene at $300\,\mathrm{K}$ is $30.15\,\mathrm{Wm^{-1}K^{-1}}$ (zigzag) and $13.65\,\mathrm{Wm^{-1}K^{-1}}$ (armchair), showing an obvious anisotropy along different directions. The calculated thermal conductivity fits perfectly to the inverse relation with temperature when the temperature is higher than Debye temperature ($Θ_D = 278.66\,\mathrm{K}$). In comparison to graphene, the minor contribution around $5\%$ of the ZA mode is responsible for the low thermal conductivity of phosphorene. In addition, the representative mean free path (MFP), a critical size for phonon transport, is also obtained.
