description: In this article we give an in depth overview of the recent advances in the field of equilibrium networks. After outlining this topic, we provide a novel way of defining equilibrium graph (network) ensembles. We illustrate this concept on the classical random graph model and then survey a large variety of recently studied network models. Next, we analyze the structural properties of the graphs in these ensembles in terms of both local and global characteristics, such as degrees, degree-degree correlations, component sizes, and spectral properties. We conclude with topological phase transitions and show examples for both continuous and discontinuous transitions.

EEG-guided adaptive neurostimulation
normalization of the functional state.

description: The methodology of digital psychophysiological mapping was used in a group of 18 stroke patients and a matched group of healthy controls to reveal possible markers of acute cerebrovascular accident. The patients were found to have a number of indicators that were significantly different from the norm and could claim the role of stroke biomarkers. Among them there are lowered values of the power and peak frequency of the EEG alpha rhythm, significantly lowered HRV indices, as well as a significantly higher levels of emotional disadaptation. Stroke patients participated in a treatment session, in which they were exposed to EEG-based bimodal (light-musical) adaptive neurostimulation, in which some EEG characteristics (EEG oscillators) control sound (musical) stimulation, and other EEG characteristics (native EEG) simultaneously control light stimulation. As a result of the treatment, patients demonstrated a normalization of all the described indicators of the functional state: the values of a power and frequency of the EEG alpha rhythm significantly increased and approached the norm, as well as the parameters of the cardiovascular system and the cognitive-emotional sphere of stroke patients. The method of EEG-guided adaptive neurostimulation used in this work demonstrates the possibility of effective cognitive rehabilitation of stroke patients even with a single application.

description: Currently, we continue to actively develop a high-tech rehabilitation method of microwave therapy using suband millimeter-wave radiation sources. However, the question of the feasibility of its use in the rehabilitation of patients with burn injuries is not sufficiently studied. In this connection, the works analyzing the effectiveness of the influence of different micro-wave ranges on the nature and degree of development of adaptive metabolic and vascular reactions in the early period of trauma, which affect the outcome of the burn, become particularly relevant. The study was carried out on male rats of the Wistar line under conditions of experimental contact thermal burn of the IIIА degree on an area of 20% of the dorsal surface of the body. A 7-day course of point non-contact exposure to broadband microwave emitters of various ranges with a radiation power of 10 µW on the occipital protuberance area was started after the rats were released from anesthesia when the contact burn was applied. The vascular status, the state of oxidative stress and energy homeostasis were assessed by the intensity of oxidative processes, antioxidant protection, and the total microcirculation index with a wavelet analysis. The obtained data reliably revealed a more pronounced favorable effect on the level of adaptive reactions in the range of 150,179-150.664 GHz, which contains the frequencies of radiation and absorption of nitric oxide. This should be taken into account when choosing frequency-energy parameters and developing a potential method of rehabilitation in the acute period of burn injury.

description: CONTEXT. Many O-type stars have nearby companions whose presence hamper their characterization through spectroscopy. AIMS. We want to obtain spatially resolved spectroscopy of close O-type visual binaries to derive their spectral types. METHODS. We use the Space Telescope Imaging Spectrograph (STIS) of the Hubble Space Telescope (HST) to obtain long-slit blue-violet spectroscopy of eight Galactic O-type stars with nearby visual companions and use spatial-profile fitting to extract the separate spectra. We also use the ground-based Galactic O-Star Spectroscopic Survey (GOSSS) to study more distant visual components. RESULTS. We spatially resolve seven of the eight systems, present spectra for their components, and obtain their spectral types. Those seven multiple systems are iota Ori Aa,Ab,B, 15 Mon Aa,Ab,C, tau CMa Aa,Ab,B,C,D,E, HD 206 267 Aa,Ab,C,D, HD 193 443 A,B, HD 16 429 Aa,Ab, and IU Aur A,B. This is the first time that spatially resolved spectroscopy of the close visual binaries of those systems is obtained. We establish the applicability of the technique as a function of the separation and magnitude difference of the binary.

description: The aim of the work was to study the effects of photobiomodulation (PBM) in the red spectrum (640 nm) with fluences from 3 mJ/cm2 to 2 J/cm2 in combination with ionizing radiation (IR) at doses of 2-6 Gy against human BJ-5ta-hTERT postnatal fibroblasts. The cells were exposed to low-intensity red light before or after their exposure to IR, the viability of the cells was determined by MTT 24 hours after the last exposure. It is shown that the effects of PBM depend on the fluence of PBM, the dose of IR and the sequence of the actions of these physical factors on cells. The adaptive effect of PBM was observed only for high fluences-1 and 2 J/cm2 when exposed to PBM and subsequent (after 1 hour) irradiation of IR. At the same time, the stimulating effect of PBM was observed only for low fluences from 3 to 300 mJ/cm2 under IR irradiation and subsequent (after 1 hour) exposure to PBM. These data should be taken into account when using PBM for the correction of adverse events of radiation therapy in an oncological clinic.

description: We study the mechanics of Hayward's trapping horizons, taking isolated horizons as equilibrium states. Zeroth and second laws of dynamic horizon mechanics come from the isolated and trapping horizon formalisms respectively. We derive a dynamical first law by introducing a new perturbative formulation for dynamic horizons in which "slowly evolving" trapping horizons may be viewed as perturbatively non-isolated.

description: © 2020, The Author(s). Background: Meaningful variations in physician performance are not always discernible from the medical record. Objective: We used unannounced standardized patients to measure and provide feedback on care quality and fidelity of documentation, and examined downstream effects on reimbursement claims. Design: Static group pre-post comparison study conducted between 2017 and 2019. Setting: Fourteen New Jersey primary care practice groups (22 practices) enrolled in Horizon BCBS’s value-based program received the intervention. For claims analyses, we identified 14 additional comparison practice groups matched on county, practice size, and claims activity. Participants: Fifty-nine of 64 providers volunteered to participate. Intervention: Unannounced standardized patients (USPs) made 217 visits portraying patients with 1–2 focal conditions (diabetes, depression, back pain, smoking, or preventive cancer screening). After two baseline visits to a provider, we delivered feedback and conducted two follow-up visits. Measurements: USP-completed checklists of guideline-based provider care behaviors, visit audio recordings, and provider notes were used to measure behaviors performed and documentation errors pre- and post-feedback. We also compared changes in 3-month office-based claims by actual patients between the intervention and comparison practice groups before and after feedback. Results: Expected clinical behaviors increased from 46% to 56% (OR = 1.53, 95% CI 1.29–1.83, p < 0.0001), with significant improvements in smoking cessation, back pain, and depression screening. Providers were less likely to document unperformed tasks after (16%) than before feedback (18%; OR = 0.74, 95% CI 0.62 to 0.90, p = 0.002). Actual claim costs increased significantly less in the study than comparison group for diabetes and depression but significantly more for smoking cessation, cancer screening, and low back pain. Limitations: Self-selection of participating practices and lack of access to prescription claims. Conclusion: Direct observation of care identifies hidden deficits in practice and documentation, and with feedback can improve both, with concomitant effects on costs.
EQUILIBRIUM SEDIMENTATION OF MONODISPERSE SOLUTES

Publisher: name: American University

description: Two procedures have been proposed to compute the z-average molecular weight, M$\sb{\rm z},$ of a solute from its equilibrium concentration curve in a solution sample in a controlled centrifugal field. The first proposed procedure operates on data from equilibrium sedimentation at a single rotor speed. Graphical differentiation is applied to the concentration curve to obtain a polynomial expression for the concentration gradient function of radial solution depth. The resulting polynomial expression is evaluated at the radial boundaries of the solution sample to obtain the concentration gradients required to compute M$\sb{\rm z}.$ The objective of this procedure is to obtain the concentration gradients at the boundaries as boundary intercepts rather than as boundary slopes. The proposed computation procedure was tested by its application to data from equilibrium sedimentation of the monodisperse solutes, sucrose and sucrose octaacetate. The proposed computation procedure, by graphical differentiation, was compared with the established computation procedure in which the required concentration gradients at the solution boundaries are obtained by numerical differentiation of a polynomial expression for the concentration curve. The M$\sb{\rm z}$ values from both procedures were equally higher than the known molecular weight of these two solutes. The ratios of M$\sb{\rm z}$ to the weight average molecular weight, M$\sb{\rm z}$/M$\sb{\rm w},$ were also computed by each procedure. The two sets of M$\sb{\rm z}/$M$\sb{\rm w}$ values were not significantly different. The proposed procedure to compute M$\sb{\rm z}$ by graphical differentiation of the concentration curve was also demonstrated by its application to data from equilibrium sedimentation of a polystyrene known to have a broad molecular weight distribution. The second proposed computation procedure operates on data from equilibrium sedimentation at a series of rotor speeds. The equation for this computation procedure,(UNFORMATTED TABLE OR EQUATION FOLLOWS)$${\rm M\sb{z} = {(dc/d\xi)\sb{b} - (dc/d\xi)\sb{m}\over\lambda(c\sb{b} - c\sb{m})},}$$(TABLE/EQUATION ENDS)is derived. This computation procedure is demonstrated by its application to polystyrene solution samples equilibrated in a wide range of centrifugal fields. In this procedure M$\sb{\rm z}$ is equal to the slope of a plot of the numerator versus the denominator in a multispeed experiment. The denominator provides the advantage of normalizing the data from multiple samples of the same solution in a series of centrifugal fields.

description: The actuality of the problem of thermal trauma is determined by its high prevalence. Severe disorders of central, regional and peripheral hemodynamics are developing with a predominant violation of microcirculation and metabolic processes in the body during burn disease. Promising NO donors suitable for biomedical use are dinitrosyl iron complexes (DNIC). The aim of the study was to evaluate the effect of DNIC on the state of microcirculation in normal conditions and on the model of combined thermal trauma (CTT). The experiments were carried out on white male rats of the Wistar line. CTT (contact burn on the area of 20% of the body surface and thermal inhalation exposure to hot air and combustion products for 20-30 seconds) was applied under anesthesia. Animals with CTT were treated daily with intraperitoneal injections of a 10% DNIC solution (1 ml; 0.3 micromol/l). Laser Doppler flowmetry was used to assess the dynamics of the microcirculation state. The physiological and biochemical mechanisms of microcirculation disorders in CTT are revealed in the work. There was an increase in the endothelial, neurogenic and respiratory components of microcirculation, microhemodynamics of the border area of the burn, and the index of the microcirculation bypass. It was shown that when using 0.3 micromol/l of DNIC in rats under normal conditions, there is a decrease in the neurogenic and respiratory components, an increase in perfusion and the myogenic component of the microcirculatory channel. The role of 0.3 micromol/l of DNIC in the normalization of microcirculation in CTT was established.

We comment on resulting peculiar self-couplings for the gauge sector, as well as on background contribution for gaugino masses. Furthermore, a non-polynomial generalization is presented.

description: IGR J17591-2342 is a recently INTEGRAL discovered accreting millisecond X-ray pulsar that went into outburst around July 21, 2018. To better understand the physics acting in these systems during the outburst episode we performed detailed temporal-, timing- and spectral analyses across the 0.3-300 keV band using data from NICER, XMM-Newton, NuSTAR and INTEGRAL. The hard X-ray 20-60 keV outburst profile is composed of four flares. During the maximum of the last flare we discovered a type-I thermonuclear burst in INTEGRAL JEM-X data. We derived a distance of 7.6+/-0.7 kpc, adopting Eddington luminosity limited photospheric radius expansion burst emission and assuming anisotropic emission. In the timing analysis using all NICER 1-10 keV monitoring data we observed a rather complex behaviour starting with a spin-up period, followed by a frequency drop, a episode of constant frequency and concluding with irregular behaviour till the end of the outburst. The 1-50 keV phase distributions of the pulsed emission, detected up to $\sim$ 120 keV using INTEGRAL ISGRI data, was decomposed in three Fourier harmonics showing that the pulsed fraction of the fundamental increases from ~10% to ~17% going from ~1.5 to ~4 keV, while the harder photons arrive earlier than the soft photons for energies <10 keV. The total emission spectrum of IGR J17591-2342 across the 0.3-150 keV band could adequately be fitted in terms of an absorbed compPS model yielding as best fit parameters a column density of N_H=(2.09+/-0.05) x 10^{22} /cm2, a blackbody seed photon temperature kT_bb,seed of 0.64+/- 0.02 keV, electron temperature kT_e=38.8+/-1.2 keV and Thomson optical depth Tau_T=1.59+/-0.04. The fit normalisation results in an emission area radius of 11.3+/-0.5 km adopting a distance of 7.6 kpc. Finally, the results are discussed within the framework of accretion physics- and X-ray thermonuclear burst theory.

description: We devise a method to certify nonclassical features via correlations of phase-space distributions by unifying the notions of quasiprobabilities and matrices of correlation functions. Our approach complements and extends recent results that were based on Chebyshev's inequality [Phys. Rev. Lett. 124, 133601 (2020)]. The method developed here correlates arbitrary phase-space functions at arbitrary points in phase space, including multimode scenarios and higher-order correlations. Furthermore, our approach provides necessary and sufficient nonclassicality criteria, applies to phase-space functions beyond $s$-parametrized ones, and is accessible in experiments. To demonstrate the power of our technique, the quantum characteristics of discrete- and continuous-variable, single- and multimode, as well as pure and mixed states are certified only employing second-order correlations and Husimi functions, which always resemble a classical probability distribution. Moreover, nonlinear generalizations of our approach are studied. Therefore, a versatile and broadly applicable framework is devised to uncover quantum properties in terms of matrices of phase-space distributions.

rs10927875 polymorphism of the ZBTB17 gene.

description: Increase in the life expectancy of the population is associated with a tendency of aging in patients with chronic heart failure (CHF). Gender, age and genetic differences of the individual risk factors are still discussed in the aspect of influence on the heart failure clinical phenotype. The study aimed to identify the gender and age differences of chronic heart failure clinical characteristics in terms of the ZBTB17 gene (rs10927875) polymorphism. Materials and methods. A total of 351 patients with CHF of ischemic etiology of both genders were examined. The average age of men was 65.3±9.9, women ̶ 69.7±9.61 years. Results and conclusions: CHF of ischemic etiology in the absence of differences in the burdened family history, previous myocardial infarction (MI) observed mainly in middle-aged and elderly men and elderly and senile women. Significant gender differences in comorbidities were revealed: in 40% of men, CHF was associated with chronic obstructive pulmonary disease (COPD), in 47.3% of women ‒ with chronic kidney disease (CKD) and in 32.2% with diabetes mellitus (DM). The distribution of rs10927875 polymorphism ZBTB17 genotypes were corresponded to the Hardy-Weinberg equilibrium (χ2 = 0.272, p = 0.873). CC genotype in men was associated with reduced left ventricular ejection fraction (LVEF). CT genotype in women associated with CHF FC III and IV due to the frequent indications in the past on myocardial infarction, concomitant DM, obesity and hypercholesterolemia. The CT genotype rs10927875 was characterized by a frequent combination of CHF with COPD in men and CKD and DM in women.

description: Objectives: to evaluate the efficacy and safety of circular radiofrequency ablation of the pulmonary trunk and main pulmonary arteries in patients with severe pulmonary hypertension using a histological study. Materials and methods: for the analysis of autopsy material from non-operated patients, three study groups were identified. Experimental ­– with chronic pulmonary hypertension with mitral disease and radiofrequency ablation. Comparisons – with severe pulmonary hypertension and without radiofrequency ablation. Control – without pulmonary hypertension and radiofrequency ablation, who died from causes not associated with cardiovascular diseases. Hematoxylin and eosin staining according to Van Gieson was used to visualize the damage to the tissue samples of the vascular wall. The technique of impregnation with silver staining was used to determine the damage to the nerve plexuses and endings. Results: analysis of the results of optical density and the relative average area of argentophilic fibers revealed a decrease in these parameters in the ablation group. In patients of the comparison group, where a high level of pulmonary hypertension was also observed, there was a significant accumulation of argentophilic fibers. Conclusion: histological examination showed an increase in the formation of sympathetic nerves in the adventitia of the pulmonary arteries in severe pulmonary hypertension. The same pulmonary arteries denervation procedure is an effective and safe way of denervation of the sympathetic plexuses located in the adventitia layer of the pulmonary arteries, which is confirmed by histological studies.

description: The work aimed to study the protein spectrum, morpho-functional state of erythrocyte membranes under stress and correction by low-intensity laser radiation. The experiments were carried out in vitro. Low-intensity laser radiation with a wavelength of 830 nm and a power of 90 mw was used for irradiation. Laser therapy was performed using an autonomous laser shower "MarsIK" (NPO "Petrolaser", St. Petersburg). The protein fractions of red blood cells were analyzed by electrophoresis, the morphology of red blood cells by laser interference microscopy, the еletrophoretic mobility of erythrocytes was measured by microelectrophoresis in our modification and the concentration of malondialdehyde in red blood cells by reaction with thiobarbituric acid spectrophotometrically. It is proved that the change of protein fractions in the erythrocyte membrane under stress, a decrease in the amount of spectrin, band 3 protein, glycophorin and ankirin. The stress is characterized by an increase in the number of echinocytes, stomatocytes and degenerative-altered red blood cells. Exposure to LLLT on blood samples determined the recovery of the studied parameters to the control group values (physiological norm). The role of the discovered metabolic changes in RBC in stress and their correction by LLLT is under discussion.

description: Inclusive $J/ψ$ productions in $e^+ e^-$ annihilation is studied in the framework of NRQCD. We first review the leading-order calculations of the cross sections for $e^+ e^- \to J/ψc \bar{c}$ and $e^+ e^- \to J/ψg g$ and find that their ratio is about 1:1.5 at $\sqrt{s}\simeq 10$\gev. This result is in conflict with the current measurements by the Belle Collaboration, which finds that the process $e^+e^- \to J/ψc\bar{c}$ accounts for about 2/3 of all the prompt $J/ψ$'s. We show that the discrepancy in the total rate as well as in the $J/ψ$ momentum distributions can be resolved by considering a large renormalization $K$ factor ($K\simeq 4$) for the $J/ψc \bar {c}$ cross section and by taking into account collinear suppression in the end-point energy region of $J/ψg g$ production. Detailed studies of the model predictions in terms of the density matrix are performed and various momentum and angular distributions are presented as functions of the $K$ factors. These distributions can be used to determine the normalizations of each subprocess provided that the production and decay angular distributions do not alter much by higher order corrections.

LOCUS-OF-CONTROL, GENDER AND TYPE OF MAJOR AS CORRELATES TO STATISTICS ANXIETY IN COLLEGE STUDENTS
Creators: name: DeMaria Mitton, Paula Ann
Publisher: name: American University
Year: 2023

description: This study proposed: (1) to determine the relationship of locus of control, gender, and type of major to statistics anxiety in students taking an introductory statistics course at the college level, and (2) to draw implications from these findings regarding the need for instructional attention to these constructs as a means of enhancing statistics competence at the college level. The Revised Mathematics Anxiety Rating Scale, Rotter's Internal-External Scale, and the Personal Data Form were used respectively to assess statistics anxiety, locus-of-control orientation (internal or external) and personal characteristics (age, prior statistics experience, gender, type of major, and enrollment status). These instruments were completed by 702 college student volunteers from The American University (249 students from nine classes), George Washington University (257 students from seven classes) and York College (196 students from seven classes), during the beginning of their first introductory level statistics course in the Fall of 1986. These schools are all private, four-year, liberal arts, post-secondary institutions. Findings were that female study subjects starting an introductory level statistics course had more statistics anxiety than their male counterparts. Using the t test, statistics anxiety was found to be significantly related to gender at the p $<$.05 level. Age was also found to be significantly related to statistics anxiety at the p $<$.05 level. Of the study subjects taking an introductory statistics course, those "19 and younger" were found to have significantly less statistics anxiety than those "20 and older". The investigator recommended that programs be developed from the elementary school through college level, to counter sex-role stereotypes which depict females as having poor math aptitude. It was also recommended that statistics-anxiety-reducing strategies be developed and incorporated in introductory statistics courses. These strategies should target women and students "20 and older".

title: Dynamic Bayesian smooth transition autoregressive (DBSTAR) models for non-stationary nonlinear time series
Creators: name: dos Santos, Alexandre Jose
Publisher: name: The Open University
Year: 2014

description: In this thesis, Dynamic Bayesian Smooth Transition Autoregressive (DBSTAR) models are proposed for nonlinear time series, as an alternative to both the classical Smooth Transition Autoregressive (STAR) models and Computational Bayesian STAR (CBSTAR) models. DBSTAR models are autoregressive formulations of dynamic linear models based on polynomial approximations of transition functions of STAR models. Unlike classical STAR and CBSTAR models, their parameters vary in time, being suitable for modelling both global and local non-stationary processes. Since DBSTAR models are Bayesian, the models do not require extensive historical data for parametric estimation and allow expert intervention via prior distribution assessment of model parameters. Because they are analytical and sequential, DBSTAR models, respectively, avoid potential computational problems associated with CBSTAR models, such as convergence issues, and allow fast estimation of dynamic parameters sequentially in time, being thus suitable for real time applications. Proposed DBSTAR models have been applied to two data sets: the much used Canadian Lynx data set, in which the aim is to validate DBSTAR models by comparing their fitting performances with existing approaches in the literature, and a Brazilian electricity load data set, for which existing models are not suitable.

description: The article focuses on identifying specific eye movement parameters during reading unfamiliar words to study the formation of epistemic evaluation. The sample consisted of 40 students. 240 eye-tracking records were registered while the participants were reading 6 texts in Russian. The study revealed that the speed of saccades decreased, and the duration of fixations increased while reading an unknown word. Eye movements at first encounter of a new term may be an indicator of epistemic evaluation formation.
Collective dynamics and expansion of a Bose-Einstein condensate in a random potential

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: We investigate the dynamics of a Bose-Einstein condensate in the presence of a random potential created by optical speckles. We first consider the effect of a weak disorder on the dipole and quadrupole collective oscillations, finding uncorrelated frequency shifts of the two modes with respect to the pure harmonic case. This behaviour, predicted by a sum rules approach, is confirmed by the numerical solution of the Gross-Pitaevskii equation. Then we analyze the role of disorder on the one-dimensional expansion in an optical guide, discussing possible localization effects. Our theoretical analysis provides a useful insight into the recent experiments performed at LENS [J. Lye et al., Phys. Rev. Lett. 95, 070401 (2005); C. Fort et al., cond-mat/0507144].

description: SELENOM is a highly conserved protein, presented in different species and classes of animals, belongs to the family of thioredoxin–like folding proteins. It is known that SELENOM is more expressed in the brain and is very sensitive to selenium deficiency in this organ; it is involved in the regulation of calcium signaling, redox homeostasis, and apoptosis in brain cells. This study showed that SELENOM–knockdown in human glioblastoma cells (A–172 cell line) contributed to a decrease in the number of apoptotic A–172 cells after 24 or 48 h treatment with the known apoptosis inducer staurosporine, as well as a significant decrease in the number of necrotic cells after 48 h treatment with this inductor. A decrease in SELENOM ​​activity also led to a decrease in the Ca2+ ER–buffer capacity and influenced the level of mRNA expression of key ER–stress markers in glioblastoma cells.

description: Pulp diseases treatment may lead to complications, such as the development of apical periodontitis registered with the help of X-ray examination. At the same time, a dentist might provide endodontic treatment associated with apical periodontitis in case there are relevant X-ray changes. In both cases, the periapical status follow-up is required for causality assessment. CBCT data of 2915 endodontically treated teeth were studied assessing the distance from the X-ray root apex to the root filling, as well as assessing the periapical status and tracing the relation between those. It is least probable to detect periapical changes if the length of the root canal filling is 0-1 mm from the X-ray apex, more probable within the length of 1-2 mm, and most probable within the level of over 1 mm and 2 mm, correspondingly. An individual approach excludes the strategy of ‘indication — contra-indication’ related to the length of the root canal filling showing no ground to assess it as a success criterion for endodontic treatment or as an indication for retreatment regardless of the clinical case. In many situations, if there are no clinical signs of unsuccessful endodontic treatment, the periapical tissues follow-up strategy is well-grounded.
