description: We establish tight results for rapid mixing of Gibbs samplers for the Ferromagnetic Ising model on general graphs. We show that if \[(d-1)\tanhβ<1,\] then there exists a constant C such that the discrete time mixing time of Gibbs samplers for the ferromagnetic Ising model on any graph of n vertices and maximal degree d, where all interactions are bounded by $β$, and arbitrary external fields are bounded by $Cn\log n$. Moreover, the spectral gap is uniformly bounded away from 0 for all such graphs, as well as for infinite graphs of maximal degree d. We further show that when $d\tanhβ<1$, with high probability over the Erdos-Renyi random graph $G(n,d/n)$, it holds that the mixing time of Gibbs samplers is \[n^{1+Θ({1}/{\log\log n})}.\] Both results are tight, as it is known that the mixing time for random regular and Erdos-Renyi random graphs is, with high probability, exponential in n when $(d-1)\tanhβ>1$, and $d\tanhβ>1$, respectively. To our knowledge our results give the first tight sufficient conditions for rapid mixing of spin systems on general graphs. Moreover, our results are the first rigorous results establishing exact thresholds for dynamics on random graphs in terms of spatial thresholds on trees.

description: We use the evolution operator method to find the Schwinger pair-production rate at finite temperature in scalar and spinor QED by counting the vacuum production, the induced production and the stimulated annihilation from the initial ensemble. It is shown that the pair-production rate for each state is factorized into the mean number at zero temperature and the initial thermal distribution for bosons and fermions.

Factors of merit for radiation detectors
Creators: name: Unwin, Alexander Matthew
Publisher: name: University of British Columbia
Year: 2012

description: A discussion is given of the many uses of photo-conductive cells, especially of those of the lead sulphide type. A Factor of Merit for radiation detectors as proposed by Clark Jones is presented, which is intended to cover all types of detectors, and which is applied to the lead sulphide cells studied. Other Factors of Merit are also mentioned. From information obtained the Factors of Merit are evaluated for the cells. These Factors of Merit are found to vary with the temperature of the cell layer. It is found that limiting noise is not due to Johnson noise, but rather to radiation fluctuations; and that the ultimate sensitivity has been reached in some cells. The cells are assumed to be type II detectors according to Clark Jones's classification. It is found that the engineering limit proposed by R. J. Havens does not apply here. Particularly good agreement between various expressions for the Factor of Merit is shown, assuming a type II detector. A description of the apparatus is given in some detail. A black body radiator and associated temperature control, a 900 cycles per second tuned amplifier, a wide band preamplifier and a multi vibrator used in measuring time constants of such cells are described. The methods of measurement of responsivity to noise ratio, of noise, of time constants, frequency response curves and spectral response of a detector are outlined. It is found that the black body is optically aligned; tests show that the response of a cell is directly proportional to the intensity of the illumination.

A Bayesian Networks Approach to Operational Risk

description: A system for Operational Risk management based on the computational paradigm of Bayesian Networks is presented. The algorithm allows the construction of a Bayesian Network targeted for each bank using only internal loss data, and takes into account in a simple and realistic way the correlations among different processes of the bank. The internal losses are averaged over a variable time horizon, so that the correlations at different times are removed, while the correlations at the same time are kept: the averaged losses are thus suitable to perform the learning of the network topology and parameters. The algorithm has been validated on synthetic time series. It should be stressed that the practical implementation of the proposed algorithm has a small impact on the organizational structure of a bank and requires an investment in human resources limited to the computational area.
Discrete Dirac Operators, Critical Embeddings and Ihara-Selberg Functions

description: The aim of the paper is to formulate a discrete analogue of the claim made by Alvarez-Gaume et al., realizing the partition function of the free fermion on a closed Riemann surface of genus g as a linear combination of 2^{2g} Pfaffians of Dirac operators. Let G=(V,E) be a finite graph embedded in a closed Riemann surface X of genus g, x_e the collection of independent variables associated with each edge e of G (collected in one vector variable x) and S the set of all 2^{2g} Spin-structures on X. We introduce 2^{2g} rotations rot_s and (2|E| times 2|E|) matrices D(s)(x), s in S, of the transitions between the oriented edges of G determined by rotations rot_s. We show that the generating function for the even subsets of edges of G, i.e., the Ising partition function, is a linear combination of the square roots of 2^{2g} Ihara-Selberg functions I(D(s)(x)) also called Feynman functions. By a result of Foata--Zeilberger holds I(D(s)(x))= det(I-D'(s)(x)), where D'(s)(x) is obtained from D(s)(x) by replacing some entries by 0. Thus each Feynman function is computable in polynomial time. We suggest that in the case of critical embedding of a bipartite graph G, the Feynman functions provide suitable discrete analogues for the Pfaffians of discrete Dirac operators.

description: STFM (Spill, Transport and Fate Model) is a computational model for oil spill’s simulation, its objective is to provide a technical and scientific tool adapted to the needs of decision makers and Brazilian researchers. The algorithms were developed based on physicochemical formulations proposed in the literature, testing the propositions of several authors and selecting the equations that presented the best results to integrate the set of weathering that compose the STFM. The results showed that the STFM presented performance consistent with the recent evolutions in this field of science, the model uses a “Randon Flight” equation for the Lagrangean elements scattering and the Lynch and Fingas combination equations for the weathering of the spilled oil. The STFM simulates all the main processes acting on offshore oil slicks including: advection, turbulent diffusion, surface scattering, evaporation, dissolution, emulsification, sedimentation and the oil slick's interaction with the shoreline. The validation of the model was performed by comparing the results with other consolidated models in the literature.

description: This study focuses on the transition from horse-powered to automotive transit in Washington, DC and explores how the city’s cultural landscape was adapted to fit this new means of transportation. Three main sources are used to establish an inventory of horse- and automotive-related structures: Sanborn Fire Insurance Maps, Baist’s Real Estate Atlas of Surveys, and Boyd’s City Directories of the District of Columbia. Inventoried structures are documented in their form and function between 1888 and 1935 to further understand the transitional period between transportation methods and changes to the city’s infrastructure and livelihood. Documented changes are analyzed further in the context of the increasing prominence of the automobile in the 20th century. Trends in car manufacturing, specifically the Ford company, are included to support trends found in the analysis. Additionally, an inventory of extant structures is conducted to better understand the fate of these structures and their contemporary uses, if any.

description: Nano- and microplastic particles (NMP) are strong environmental contaminants affecting marine ecosystems and human health. The negligible use of biodegradable plastics and the lack of knowledge about plastic uptake, accumulation, and functional consequences led us to investigate the short- and long-term effects in freshly isolated skin cells from mice. Using fluorescent NMP of several sizes (200 nm to 6 µm), efficient cellular uptake was observed, causing, however, only minor acute toxicity as metabolic activity and apoptosis data suggested, albeit changes in intracellular reactive species and thiol levels were observed. The internalized NMP induced an altered expression of various targets of the nuclear factor-2-related transcription factor 2 pathway and were accompanied by changed antioxidant and oxidative stress signaling responses, as suggested by altered heme oxygenase 1 and glutathione peroxide 2 levels. A highly increased beta-catenin expression under acute but not chronic NMP exposure was concomitant with a strong translocation from membrane to the nucleus and subsequent transcription activation of Wnt signaling target genes after both single-dose and chronic long-term NMP exposure. Moreover, fibroblast-to-myofibroblast transdifferentiation accompanied by an increase of α smooth muscle actin and collagen expression was observed. Together with several NMP-induced changes in junctional and adherence protein expression, our study for the first time elucidates the acute and chronic effects of NMP of different sizes in primary skin cells' signaling and functional biology, contributing to a better understanding of nano- and microplastic to health risks in higher vertebrates.
On Radiation Pressure in Static, Dusty HII Regions
Creators: name: Draine, B. T.

Year: 2010
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Radiation pressure acting on gas and dust causes HII regions to have central densities that are lower than the density near the ionized boundary. HII regions in static equilibrium comprise a family of similarity solutions, parametrized by 3 parameters: beta, gamma, and the product (Q_0 n_rms); beta characterizes the stellar spectrum, gamma characterizes the dust/gas ratio, Q_0 is the ionizing output from the star (photons/s), and n_rms is the rms density within the ionized region. Adopting standard values for beta and gamma, varying (Q_0 n_rms) generates a one-parameter family of density profiles, ranging from nearly uniform density (small Q_0 n_rms), to hollow-sphere HII regions (large Q_0 n_rms). When (Q_0 n_rms) exceeds 10^{52} cm^{-3} s^{-1}, dusty HII regions have conspicuous central cavities, even if no stellar wind is present. For given beta, gamma and (Q_0 n_rms), a fourth quantity, which can be Q_0, determines the overall size and density of the HII region. Examples of density and emissivity profiles are given. We show how quantities of interest -- such as the peak-to-center emissivity ratio, the rms-to-mean density ratio, the edge-to-rms density ratio, and the fraction of the ionizing photons absorbed by the gas -- depend on the 3 parameters beta, gamma, and (Q_0 n_rms). For dusty HII regions, compression of the gas and dust into an ionized shell results in a substantial increase in the fraction of the >13.6 eV photons that actually ionize H (relative to a uniform density HII region with the same dust/gas ratio and density n=n_rms). We discuss the extent to which radial drift of dust grains in HII regions can alter the dust-to-gas ratio. The applicability of these solutions to real HII regions is discussed.

description: This is an English translation of a
      story for children entitled "Gongitsune" written by the
      Japanese writer Niimi Nankichi. It speaks of an orphaned fox
      who develops sympathy for a peasant whose mother dies,
      leaving him alone in the world. However, the peasant fails to
      understand the kindnesses of the little fox and the story
      takes a tragic end. In Japanese folk tradition and literature
      the fox (kitsune) is often an ambiguous creature who can take
      on human characteristics in a provisional manner (hence
      gon-), often teasingly. Here the tricks of the little fox are
      overlaid by his compassionate actions. The present document
      file is entitled Gongitsuné A (translation). An explanatory
      postscript to this story is in preparation and will be
      published in the same place in due course under the document
      title Gongitsuné B (postscript).

description: Abstract: The aim of this study was to identify the psychological pain among Jerusalem’s elderly over the age of 65. The sample of the study consisted of 80 elderly people. To achieve the study’s goals, the descriptive approach and psychological pain scale were used. The findings revealed a moderate level of psychological pain among Jerusalem’s elderly. Furthermore, there were statistically significant differences due to academic qualification in favor of university and higher degree. The findings also revealed differences attributable to the gender variable in favor of males, whereas there were no statistically significant differences due to the number of children variable. This means that the pandemic caused additional psychological pain in the lives of the elderly.

description: We report on terahertz (THz) quantum-cascade lasers (QCLs) based on GaAs/AlAs heterostructures, which exhibit single-mode emission at 3.360, 3.921, and 4.745 THz. These frequencies are in close correspondence to fine-structure transitions of Al atoms, N+ ions, and O atoms, respectively. Due to the low electrical pump power of these THz QCLs, they can be operated in a mechanical cryocooler in continuous-wave mode, while a sufficient intrinsic tuning range of more than 5 GHz is maintained. The single-mode operation and the intrinsic tuning range of these THz QCLs allow for the application of these lasers as radiation sources for high-resolution absorption spectroscopy to determine the absolute densities of Al atoms, N+ ions, and O atoms in plasmas.

description: We present quantitative analysis of various (syntactic and behavioral) properties of random λ-terms. Our main results are that asymptotically all the terms are strongly normalizing and that any fixed closed term almost never appears in a random term. Surprisingly, in combinatory logic (the translation of the λ-calculus into combinators), the result is exactly opposite. We show that almost all terms are not strongly normalizing. This is due to the fact that any fixed combinator almost always appears in a random combinator.

description: A single crystal sodium iodide spectrometer has been developed for the investigation of gamma-ray spectra. The spectrometer was tested with the gamma-rays from the sources Eu¹⁵⁵,RaD, Na²², Zn⁶⁵, Co⁶⁰, and RdTh. The spectra from these sources have been obtained by analyzing the pulse height distribution from the scintillation counter with a single channel differential discriminator. A crystal mounting technique is described in which the crystals are mounted dry with a layer of magnesium oxide powder surrounding them to provide diffuse reflecting surfaces. With mountings of this type, 7% energy resolution has been achieved for gamma-ray energies of approximately 1 MeV. The expected pulse height distributions have been calculated and compared with the experimental distributions. The effect of multiple scattering events on the shape of the distributions is discussed,2and the effect of crystal dimensions on the resolution has been studied. It has been found that for the energy region 0.5 to 2.5 MeV the best resolution is obtained with small crystals. A search has been made for the presence of low energy gamma-rays in the decay of tritium, and it was found that within the accuracy of the experiment no gamma-rays were present. A preliminary report is presented on the investigation of possible scintillation produced in air by alpha particles. The effect has been shown to exist but no systematic study has been made.

description: Gas plasma is a medical technology with antimicrobial properties. Its main mode of action is oxidative damage via reactive species production. The clinical efficacy of gas plasma-reduced bacterial burden has been shown to be hampered in some cases. Since the reactive species profile produced by gas plasma jets, such as the kINPen used in this study, are thought to determine antimicrobial efficacy, we screened an array of feed gas settings in different types of bacteria. Antimicrobial analysis was performed by single-cell analysis using flow cytometry. We identified humidified feed gas to mediate significantly greater toxicity compared to dry argon and many other gas plasma conditions. The results were confirmed by inhibition zone analysis on gas-plasma-treated microbial lawns grown on agar plates. Our results may have vital implications for clinical wound management and potentially enhance antimicrobial efficacy of medical gas plasma therapy in patient treatment.

description: Polystyrene nano- and micro-sized plastic particles (NMP) are one of the common plastic materials produced that dramatically pollute the environment, water, and oceanic habitats worldwide. NMP are continuously absorbed by the body through a number of routes, especially via intestinal ingestion, dermal uptake, and inhalation into the lung. Several studies provided evidence of NMP provoking oxidative stress and affecting cellular responses. Yet, the NMP effects on primary lung cells have not been studied. To this end, we isolated and cultured murine lung cells and exposed them short-term or long-term to polystyrene 0.2–6.0 µm-sized NMP. We studied cellular consequences regarding oxidative stress, morphology, and secretion profiling. Visualization, distribution, and expression analyses confirmed lung cells accumulating NMP and showed several significant correlations with particle size. Moreover, we found substantial evidence of biological consequences of small-scale NMP uptake in lung cells. Besides alterations of cytokine secretion profiles resulting in inflammatory responses, indicators of oxidative stress were identified that were accompanied by Nrf2 and β-catenin signaling changes. Our results serve as an important basis to point out the potential hazards of plastic contaminations and uptake in lung cells.

description: Over the past 15 years, investigating the efficacy of non-invasive physical plasma (NIPP) in cancer treatment as a safe oxidative stress inducer has become an active area of research. So far, most studies focused on the NIPP-induced apoptotic death of tumor cells. However, whether NIPP plays a role in the anti-tumor immune responses need to be deciphered in detail. In this review, we summarized the current knowledge of the potential effects of NIPP on immune cells, tumor–immune interactions, and the immunosuppressive tumor microenvironment. In general, relying on their inherent anti-oxidative defense systems, immune cells show a more resistant character than cancer cells in the NIPP-induced apoptosis, which is an important reason why NIPP is considered promising in cancer management. Moreover, NIPP treatment induces immunogenic cell death of cancer cells, leading to maturation of dendritic cells and activation of cytotoxic CD8+ T cells to further eliminate the cancer cells. Some studies also suggest that NIPP treatment may promote anti-tumor immune responses via other mechanisms such as inhibiting tumor angiogenesis and the desmoplasia of tumor stroma. Though more evidence is required, we expect a bright future for applying NIPP in clinical cancer management.

description: It is well-known that the partition function of the unitary ensembles of random matrices is given by a tau-function of the Toda lattice hierarchy and those of the orthogonal and symplectic ensembles are tau-functions of the Pfaff lattice hierarchy. In these cases the asymptotic expansions of the free energies given by the logarithm of the partition functions lead to the dispersionless (i.e. continuous) limits for the Toda and Pfaff lattice hierarchies. There is a universality between all three ensembles of random matrices, one consequence of which is that the leading orders of the free energy for large matrices agree. In this paper, this universality, in the case of Gaussian ensembles, is explicitly demonstrated by computing the leading orders of the free energies in the expansions. We also show that the free energy as the solution of the dispersionless Toda lattice hierarchy gives a solution of the dispersionless Pfaff lattice hierarchy, which implies that this universality holds in general for the leading orders of the unitary, orthogonal, and symplectic ensembles. We also find an explicit formula for the two point function $F_{nm}$ which represents the number of connected ribbon graphs with two vertices of degrees n and m on a sphere. The derivation is based on the Faber polynomials defined on the spectral curve of the dispersionless Toda lattice hierarchy, and $\frac{1}{nm} F_{nm}$ are the Grunsky coefficients of the Faber polynomials.

description: Medical gas plasma is an experimental technology for anticancer therapy. Here, partial gas ionization yielded reactive oxygen and nitrogen species, placing the technique at the heart of applied redox biomedicine. Especially with the gas plasma jet kINPen, anti-tumor efficacy was demonstrated. This study aimed to examine the potential of using passive flow shaping to enhance the medical benefits of atmospheric plasma jets (APPJ). We used an in-house developed, proprietary Modular Nozzle System (MoNoS; patent-pending) to modify the flow properties of a kINPen. MoNoS increased the nominal plasma jet-derived reactive species deposition area and stabilized the air-plasma ratio within the active plasma zone while shielding it from external flow disturbances or gas impurities. At modest flow rates, dynamic pressure reduction (DPR) adapters did not augment reactive species deposition in liquids or tumor cell killing. However, MoNoS operated at kINPen standard argon fluxes significantly improved cancer organoid growth reduction and increased tumor immunogenicity, as seen by elevated calreticulin and heat-shock protein expression, along with a significantly spurred cytokine secretion profile. Moreover, the safe application of MoNoS gas plasma jet adapters was confirmed by their similar-to-superior safety profiles assessed in the hen’s egg chorioallantoic membrane (HET-CAM) coagulation and scar formation irritation assay.
