Support Points and Extreme Points for Mappings with A -Parametric Representation in C n

Let A ∈ L ( C n ) be a linear operator such that k + ( A ) < 2 m ( A ) , where k + ( A ) is the upper exponential index of A and m ( A ) = min {(cid:3)(cid:4) A ( z ), z (cid:5) : (cid:6) z (cid:6) = 1 } . In this paper we are concerned with variations of A -normalized univalent subordination chains on the Euclidean unit ball B n in C n . We also obtain growth results for the generating vector ﬁelds and the transition mappings associated with A -normalized univalent subordination chains f ( z , t ) that satisfy some regularity assumptions. Further, we give examples of normalized biholomorphic mappings on B n which are not extreme/support points for the compact family S 0 A ( B n ) of mappings with A -parametric representation on B n . Next, we consider the (normalized) time-log M -reachable family ˜ R log M ( id B n , N A ) generated by the Carathéodory mappings, where M ∈ ( 1 , ∞ ) and k + ( A ) < 2 m ( A ) . We prove a result related to the support points f of the family ˜ R log M ( id B n , N A ) and the associated A -univalent subordination chains f ( z , t ) such that f = f ( · , 0 ) . In particular, if f ∈ ˜ R log M ( id B n , N A ) ,
Automorphisms of C 2 with Parabolic Cylinders

A paraboliccylinderis an invariant, non-recurrent Fatou component (cid:2) of an automorphism F of C 2 satisfying: (1) The closure of the ω -limit set of F on (cid:2) contains an isolated ﬁxed point, (2) there exists a univalent map (cid:4) from (cid:2) into C 2 conjugating F to the translation ( z , w) (cid:2)→ ( z + 1 , w) , and (3) every limit map of { F ◦ n } on (cid:2) has one-dimensional image. In this paper, we prove the existence of parabolic cylinders for an explicit class of maps, and show that examples in this class can be constructed as compositions of shears and overshears.
THE NUMERICAL RANGE OF AN UNBOUNDED OPERATOR

The numerical range of an unbounded linear operator on a complex Banach space is the whole complex plane. Let X denote a Banach space over C, A" the dual space of X, S = (x G X: \\x\\ = 1}, and let T be an unbounded operator defined on the whole of X. Given x G S, let V(T,x) = {/(Fx):/ G A", ||/|| = f(x) = 1}. The numerical range V(T) is defined by
The selection of the order and identification of nonzero elements in the polynomial matrices of vector autoregressive processes

In this paper we show how the residual white noise autoregressive order selection procedure can be used not only to effectively identify the order of Vector Autoregressive (VAR) processes, but also with the use of a seemingly-unrelated-type of estimation method to identify nonzero elements in the polynomial matrices of VAR models. Results from extensive simulation studies as well as from economic data are presented to demonstrate the performance of the proposed method.
Techniques for Measuring Parallax and Proper Motion with VLBI

Astrometry at centimeter wavelengths using Very Long Baseline Interferometry is approaching accuracies of ∼1 μas for the angle between a target and a calibrator source separated by ≲1° on the sky. The BeSSeL Survey and the Japanese VERA project are using this to map the spiral structure of the Milky Way by measuring trigonometric parallaxes of hundreds of maser sources associated with massive, young stars. This paper outlines how μas astrometry is done, including details regarding the scheduling of observations, calibration of data, and measuring positions.
The structure of galaxy clusters in various cosmologies

We investigate the internal structure of clusters of galaxies in high-resolution N-body simulations of four different cosmologies. There is a higher proportion of disordered clusters in critical-density than in low-density universes, although the structure of relaxed clusters is very similar in each case. Crude measures of substructure, such as the shift in the position of the centre-of-mass as the density threshold is varied, can distinguish the two in a sample of just 20 or so clusters; it is harder to differentiate between clusters in open and flat models with the same density parameter. Most clusters are in a quasi-steady state within the virial radius and are well-described by the density profile of Navarro, Frenk & White.
Partitioned mixture distributions: a first order perturbation analysis

A perturbation analysis is used to linearise the theory of partitioned mixture distribution (PMD) encoder/decoder networks, which allows many connections to be made with previous results. For instance, the difference of Gaussians (DOG) filtering operation commonly used in image processing emerges very naturally, and the dependence of the wavelength of dominance stripes in a visual cortex network (VICON) may then be derived.
重型/极重型再生障碍性贫血患者免疫抑制治疗后早期死亡的临床特征及预测模型构建

目的 分析重型/极重型再生障碍性贫血（SAA/VSAA）采用抗胸腺细胞球蛋白（ATG）强化免疫抑制治疗后早期死亡（ED）患者的特征并构建ED的预测模型。 方法 收集2003年8月至2021年8月期间在北京协和医院接受ATG治疗的232例SAA/VSAA患者临床资料，回顾性分析ED（治疗后90 d内死亡）患者的临床特征、死亡原因，采用Cox比例风险模型筛选影响ED的危险因素并构建预测模型。 结果 232例SAA/VSAA患者接受ATG治疗，19例（8.2％）发生ED，中位发生时间为24（3～85）d。 ED主要原因是感染（84.2％），其次为脑出血（10.5％）。 多因素分析显示VSAA（HR＝15.359，95％ CI 1.935～121.899，P＝0.010）、采用泊沙康唑预防真菌感染（HR＝0.147，95％ CI 0.019～1.133，P＝0.066）、外周血淋巴细胞计数（LYM）≤0.5×109/L（HR＝3.386，95％CI 1.123～10.206，P＝0.030）、PLT≤5×109/L（HR＝8.939，95％ CI 1.948～41.019，P＝0.005）为ED的独立影响因素。 VSAA、采用泊沙康唑预防真菌感染、LYM≤0.5×109/L、PLT≤5×109/L分别赋3、−2、1、2分构建临床预测模型，该积分模型曲线下面积（AUC）为＝89.324（95％CI 80.859～97.789），积分≥3分患者发生ED的风险为<3分组的23. 1（95％CI 5.3～100.2）倍。 结论 感染和脑出血导致的ED是SAA/VSAA采用ATG治疗的重要挑战。 同时具有VSAA、LYM≤0.5×109/L、PLT≤5×109/L且未采用泊沙康唑预防真菌感染患者具有较高的ED发生风险。
Assessing the Validity of Health Messages Used by the Saudi Public in WhatsApp

Objective WhatsApp is the most frequently used social media platform in Saudi Arabia. Inaccurate information could negatively impact public health. The number of studies worldwide investigating health-related misinformation in social media increased steadily, with limited data from Arabic-speaking communities. This study aimed to estimate the validity and safety of Arabic-language health information messages circulated on WhatsApp and identify the different categories of these messages based on their credibility. Participants and Methods A descriptive, analytical cross-sectional study was conducted from February to April 2021. A total of 374 students were randomly selected from the common first preparatory year college at King Saud University in Riyadh, Saudi Arabia, and participated by sharing up to three health-related WhatsApp messages per student that they or their relatives had recently read. Four board-certified physicians reviewed and classified the messages based on their credibility and sources. Results 282 students provided 326 messages (1.2 messages per student). Most messages (86%) had either invalid or inaccurate content, and 83.7% came from unknown sources. Only 26 messages (8%) of the total were written by trusted scientific sources. Most of the messages from unknown sources or unqualified persons were either invalid or invalid, with potential health risks for the public, and the difference from trusted sources was statistically significant. Conclusion This study showed a high percentage of inaccurate and invalid health-related messages on WhatsApp. Invalid messages with potential health risks were authored mostly by unknown sources or unqualified persons. Most health messages written by trusted authorities and qualified persons were valid. Trusted scientific authorities should thus be more active in public education on social media platforms. They should advise their communities on how to discern the validity of such messages. More efforts are needed to guide patients from where to obtain accurate and valid health information.
Advancement of optical component control for an imaging Fabry-Perot interferometer

Risk mitigation activities associated with a prototype imaging Fabry-Perot Interferometer (FPI) system are continuing at the NASA Langley Research Center. The system concept and technology center about enabling and improving future space-based atmospheric composition missions, with a current focus on observing tropospheric ozone around 9.6 micron, while having applicability toward measurement in different spectral regions and other applications. Recent activities have focused on improving an optical element control subsystem to enable precise and accurate positioning and control of etalon plates; this is needed to provide high system spectral fidelity critical for enabling the required ability to spectrally-resolve atmospheric line structure. The latest results pertaining to methodology enhancements, system implementation, and laboratory characterization testing are discussed.
Group Eye Movement Desensitization Reprocessing (EMDR) Psychotherapy and Recurrent Interpersonal Traumatic Episodes: A Pilot Follow-Up Study

Objective To explore the acceptability and the effectiveness of an Eye Movement Desensitization Reprocessing Integrative Group Treatment Protocol (EMDR-IGTP) for patients with a history of recurrent traumatic episodes of interpersonal nature. Method Seven women were recruited from a Trauma Centre and were offered EMDR-IGTP, consisting of 10 semi-structured group sessions. Participants were assessed through a set of standardised clinical measures before the treatment, at the end of it, and after 1 and 3 months since its conclusion. Results EMDR-IGTP was well accepted by all participants. After the intervention and at 1 and 3 months follow-up, patients showed a significant reduction of dissociative symptoms, traumatic symptoms and improved emotional regulation. Conclusions This study suggests that GITM-EMDR therapy can be a helpful treatment for people who experienced traumatic episodes of interpersonal nature and supports more extensive research in this direction.
Nonsteady Effective Thermal Conductivity of Dense Fibrous Composites with Graded Interface

The multiple scattering of thermal waves by dense fibers with a functionally graded interface in composites is considered, and the analytical solution of the nonsteady effective thermal conductivity of composites is presented. The Fourier heat conduction law is applied to analyze the propagation of thermal waves in the fibrous composite. The scattering and refraction of thermal waves by cylindrical fibers with a nonhomogeneous interface layer in the matrix are expressed by using the wave function expansion method. The theory of quasi-crystalline approximation and the conditional probability density function are employed to treat the multiple scattering of thermal waves from the dense fibers. Through analysis, it is found that the nonsteady effective thermal conductivity under higher frequencies is quite different from the steady thermal conductivity. In different regions of wave frequency, the effects of the functional form of gradation and the properties and thickness of the functionally graded layers on the nonsteady effective thermal conductivity show great differences.
The main characteristic of the evolution project SuperVVER with spectrum shift regulation

Abstract The researches on the increase of achievable fuel burn-up in light water reactors (LWR) with so-called “spectrum shift” have been carried out in the world for a long time. The main idea of the “spectrum shift” is based on neutron spectrum shifting from the resonance energy region at the beginning of the cycle to the thermal region at the end of the cycle. There are many different ways of such regulation in the core – starting from coolant density variation during reactor cycle, to changing water-uranium ratio with some mechanical equipment. Spectrum shift regulation with depleted uranium or zirconium displacers is presented in this paper for uranium and mixed uranium and plutonium oxide (MOX) fuel loadings. New fuel assemblies with special guide tubes for displacers were developed for these purposes.
Feedback suppression of rotating external kink instabilities in the presence of noise

The authors report on the first experimental demonstration of active feedback suppression of rotating external kink modes near the ideal wall limit in a tokamak using Kalman filtering to discriminate the n=1 kink mode from background noise. The Kalman filter contains an internal model that captures the dynamics of a rotating, growing n=1 mode. Suppression of the external kink mode is demonstrated over a broad range of phase angles between the sensed mode and applied control field, and performance is robust at noise levels that render proportional gain feedback ineffective. Suppression of the kink mode is accomplished without excitation of higher frequencies as was observed in previous experiments using lead-lag loop compensation [A. J. Klein et al., Phys Plasmas 12, 040703 (2005)].
Measurement of bivariate attributes using a novel statistical model

Reducing process variability is essential to many organisations. According to the pertinent literature, a quality system that utilizes quality techniques to reduce process variability is necessary. Quality programs that respond to measurement precision are central to quality systems, and the most common method of assessing the precision of a measurement system is repeatability and reproducibility (R&R). Few studies have investigated R&R using attribute data. In modern manufacturing environments, automated manufacturing is becoming increasingly common; however, a measurement resolution problem exists in automatic inspection equipment, resulting in clusters and product defects. It is vital to monitor effectively these bivariate quality characteristics. This study presents a novel model for calculating R&R for bivariate attribute data. An alloy manufacturing case is utilized to illustrate the process and potential of the proposed model. Findings can be employed to evaluate and improve measurement systems with bivariate attribute data.
Proca field in a spacetime with curvature and torsion

The author considers a spin-1 (Proca) test particle in a spacetime with curvature and torsion. Within a WKB approximation, the author derives the equations of motion for the field amplitude, the current vector and the spin vector. In contrast to a spin-1/2 (Dirac) test particle, the Proca field is sensitive to all irreducible parts of the torsion tensor.
The Synthetic Dual-Doppler Analysis Technique

Abstract Synthetic dual-Doppler (SDD) is a single-Doppler analysis technique that combines measurements from two different times, provided the viewing angle changes significantly. In this study, the viability of the SDD technique is investigated through comparisons with dual-Doppler analyses. Three case studies are used for the comparisons: a mature gust front, a supercell thunderstorm, and a developing squall line. An attempt to internally establish the efficacy of SDD analyses is made by examining the temporal correlation of the single-Doppler reflectivity fields and by comparing wind fields derived from similar synthetic analyses. Results indicate that the SDD technique may be practical for the estimation of mean velocity fields of certain quasi-steady phenomena. The similarity of the SDD and conventional dual-Doppler results were found to be sensitive to the time between the two volume scans used in the SDD analyses, the angle subtended by the event, and the radii of influence of the Cressman weightin.
Reliability of Low Temperature Polycrystalline Silicon Thin-Film Transistors with Ultrathin Gate Oxide

We analyzed the reliability against the hot-carriers effect and Joule heating effects of low-temperature polycrystalline silicon (poly-Si) thin-film transistors (TFTs) with an ultrathin gate oxide film deposited by sputtering. For the hot-carrier effect, although the generation of hot-carriers was enhanced in TFT with a thin gate oxide film, no marked degradation due to direct constant voltage (DC) stress was observed in the electric characteristics even when the thickness of the gate oxide film was 9.5 nm. Regarding the effect of Joule heating on the reliability, the thickness of the oxide film markedly affected the TFT characteristics. A new degradation mode different from the conventional mode with a shift in threshold voltage owing to heat generation was observed when the oxide film was extremely thin in spite of small amount of heat generated during the application of DC stress. Regarding the reliability of the low-temperature poly-Si TFT with an ultrathin gate oxide film, the results revealed that a new degradation mode develops due to heat generation.
Acoustic driving effect on radiative decays of excitons in ZnSe/ZnS single quantum wells

We report that acoustic driving of ZnSe/ZnS quantum wells can yield ⩾30% shortening of the fast component (on the order of 102 ps) of exciton radiative decays and relatively enhanced tail emissions at greater instants. The shortening is attributed to the driving-induced relocalization of excitons to lower-energy states while the enhancement is indicative of the drift diffusion of mobile populations in the driving electric field. These results suggest that the radiative recombination predominantly occurs from localized excitons.
Internet of Things Ontology for Digital Twin in Cyber Physical Systems

The Digital Twin is one of the most important concepts in the Cyber Physical Systems (CPS) era. It can bring benefits such as simulation, monitoring or management once it joins the physical and the virtual through the Internet of Things. This concept is being adopted more and more in the academia and in the industry, but there is still a lack of methods to define and formalize the representation of the Digital Twin, as for example semantic models. Ontologies are a way of representing knowledge that can be shared between different entities, allowing a common understanding about a information. In this sense, this work proposes an ontology to represent Digital Twin in the context of CPS and embedded systems. These concepts are implemented through a proposed architecture. The proposed ideas are being evaluated with industrial case studies and some of the preliminary results are described in the paper.
A Supporting Tool for Learning to Improve Thinking Skill through Reading Activities

Thinking skill is an important skill required in most of person's activities, especially in academic level. This paper proposes a tool to support in learning thinking skills from learning by example of good published articles. The focused concept of the tool is to analyze content expression and relations of the contents as a representation of thinking process. The tool is designed to assist on assigning pre-defined content type-related tags and relation among the chosen types on each clause from the selected articles. From experiments, the results showed that the tool helps to increase learning performance. The average precision and recall scores from tagging of the participants using the tool were higher than the participant not using the tool for 0.15 and 0.22, respectively. Moreover, the participants showed significant growth in thinking skills in terms of more correct analysis and critical thinking after using the tool.
Vector‐borne protozoan and bacterial pathogen occurrence and diversity in ectoparasites of the Egyptian Rousette bat

Bats are known reservoir hosts for a wide variety of parasites and pathogens, including bacteria and protozoans. Some of these pathogens are vector‐borne, and although their role is poorly studied, ectoparasites may contribute significantly to their transmission. The aim of this study was to molecularly detect the presence of vector‐borne microorganisms in bat‐associated ectoparasites to explore their diversity and distribution in these insects. We tested the presence of Bartonella spp. , Polychromophilus spp. , and Trypanosoma spp. in bat flies and bat fleas collected from 56 Egyptian Rousette bats (Rousettus aegyptiacus), using conventional PCR. We found a high prevalence of 43.9% (47/107) of Bartonella spp. in bat flies, but a low prevalence of 6.6% (4/61) in bat fleas. Polychromophilus and Trypanosoma DNA were absent in both bat flies and bat fleas. Furthermore, we found novel gltA Bartonella sequences, as well as genotypes that are highly similar to recently described and potentially zoonotic ones. Our results show high diversity of Bartonella in bat flies, however, their role in pathogen transmission is still unknown and should be further explored.
Terminalia catappa attenuates phenylhydrazine-induced anaemia and hepato-renal toxicity in male Wistar rat by boosting blood cells, modulation of lipoproteins and up-regulation of in vivo antioxidant armouries

Abstract Aim This study investigated the haematinic, antihyperlipidaemic, hepato-renal protective effects of Terminalia catappa aqueous leaf extract on male Wistar rats exposed to phenylhydrazine toxicity. Methods Animals were exposed to phenylhydrazine (PHZ) 50 mg/kg intraperitoneal for two consecutive days thereafter, treated with T. catappa extract (100 mg/kg and 200 mg/kg) orally for 21 days. After the experimentation, animals were sedated with ketamine (70 mg/kg) and euthanized by cervical dislodgement. Blood and organs were collected for haematology and biochemical studies following standard laboratory methods. Results Our study showed that T. catappa significantly increased erythrocytes, haemoglobin, haematocrit and high density lipoprotein as well as down-regulating leukocytes, thrombocytes, ALP AST, ALT creatinine, urea, total cholesterol as well as low density lipoprotein. The liver, kidney and spleen antioxidant defence were also up-regulated against the adverse effect caused by phenylhydrazine exposure. Conclusion Terminalia catappa attenuated Phenylhydrazine-induced anaemia and hepato-renal toxicity in male Wistar rat by boosting blood cells, modulation of lipoproteins and up-regulation of in vivo antioxidant armouries.
The development of H I dissociation zones around new H II regions

We present the results of computations for a model of the time development of H I photodissociation zones in the molecular gas around O and early B main-sequence stars and their associated H II regions. The computations are for a grid of values of stellar effective temperatures (T eff ) from 20 to 45 kK (spectral types B2.5 V-O5 V) and of ambient gas particle densities from 30 to 3000 atoms cm −3 . We follow the conditions in the atomic gas in and behind the advancing dissociation front from an assumed stellar switch-on time until the ionization and associated shock front overtakes the zone of dissociation
Node Type Distribution and Its Impacts on Performance of Power Grids

The theory of complex networks has been studied extensively since its inception. However, until now, the impact of the node-type distributions is related to network topology and cannot be evaluated independently. In this paper, a network structure is modeled via an adjacency matrix (network topology) and a set of node type distribution vectors. Three specific issues that need to be considered for node type distributions in smart grid testing and planning are summarized in this paper. First, a set of metrics are proposed and defined to evaluate the impact of node-type distributions on network performance independently. Second, another metric named the generation distribution factor is proposed to evaluate the distribution of generation buses resulting from the specific function and purpose of power grids and by considering the distribution of load buses as given conditions. Third, another metric, i.e., the power supply redundancy metric based on entropy, is proposed to evaluate the inequality of load in power supply. Finally, a discrimination factor is defined to ensure the overall evaluation and comparison of different networks is made for this inequality. All proposed metrics can be applied to the IEEE-30, IEEE-118, IEEE-300 bus systems, as well as Italian power grid components. The simulation results indicate that the IEEE-118 system has the best node type distribution and minimum discrimination; the Italian system has the worst node-type distribution and most serious discrimination of load power supply.
