DOUBLE STAR INITIAL RESULTS OF MAGNETOTAIL CURRENT SHEET

Abstract. The newly launched DSP (Double Star Program), the first Chinese space science mission, in complement with the highly successful Cluster mission, have improved our current knowledge about the key processes of the energy release and transfer in the Sun-Earth system. In this paper, we present some initial results of magnetotail current sheet observed by DSP in conjunction with Cluster. 1. Introduction The Double Star Program (DSP) is the first Chinese space science mission. The mission, in cooperation with ESA, consists of two spacecraft with carefully designed orbits to coordinate with the CLUSTER mission for important conjunctions (Liu et al, 2005). The first Double Star satellite, known as TC-1 which comes from Chinese abbreviation of “Explorer 1”, was launched on December 29, 2003 into a nearly equatorial orbit with an apogee just about 13 R E and a perigee altitude of 570 km. The second satellite, TC-2 was launched six months later on July 24, 2004 into a polar orbit with an apogee of 7 R
Comparison of the vascular floral anatomy of Xerophyllum asphodeloides (L.) Nutt. and X. tenax (Pursh) Nutt. (Liliaceae-Melanthioideae)

The patterns of floral vascularization in Xerophyllum tenax and X. asphodeloides (Liliaceae-Melanthioideae) are presented and compared. Both species share a threebundled (lower), a six-bundled (middle), and a 12-bundled (upper) pedicel vascular configuration. The upper configuration consists of six outer, smaller bundles which alternate with six inner, larger bundles. The six smaller bundles are fusion products formed at lower pedicel levels and directly supply the two whorls of tepals. Each tepal-supplying bundle divides to form a median and two laterals. There is further subdivision of the laterals within the freed tepals. The six larger remaining bundles undergo repeated radial divisions and fusions to form the two whorls'-of stamen traces. The outer stamen traces are formed in a similar manner as the inner stamen traces. Both are fusion products and their formation closes the gaps left by the departing tepal supply bundles. Axial continuations of these six larger bundles undergo one final radial division to form the fusion dorsals and the free ventrals. The ventrals have a reversed arrangement of their conducting elements. Septal axials, dorsal laterals, and ventral laterals do not occur in either species. Xerophyllum asphodeloides has two basal ovules and two associated funicular traces per locule, whereas X. tenax has four ovules and four funicular traces arranged in two tiers per locule. The vascularization of the former represents a simplified version of the latter. The gynoecium in both species is tricarpellate and unilocular with three free styles. Dorsal notches are present, as well as deep septal indentations. Rhaphides occur in both species, but their abundance increases with maturity. The capsule fruit in both species dehisces loculicidally. Xerophyllum. tenax has a papilloid carpellary epidermis which X. asphodeloides does not. Both species have an internal stigmatoidal support system for pollen tube growth which lines the inner styles and the axial faces of the inner septal wing margins.

Flame stability limits of premixed low-swirl combustion

The objective of this study is to gain a fundamental understanding of the flow-field and flame behaviors associated with a low-swirl burner. A vane-type low-swirl burner with different swirl numbers has been developed. The velocity field measurements are carried out with particle image velocimetry. The basic flame structures are characterized using OH radicals measured by planar laser-induced fluorescence. Three combustion regimes of low-swirl flames are identified depending on the operating conditions. For the same low-swirl injector under atmospheric conditions, attached flame is first observed when the incoming velocity is too low to generate vortex breakdown. Then, W-shaped flame is formed above the burner at moderate incoming velocity. Bowl-shaped flame structure is formed as the mixture velocity increases until it extinct. Local extinction and relight zones are observed in the low-swirl flame. Flow-field features and flame stability limits are obtained for the present burner.
Analysis of Infrastructural Challenges, Cybercrime, and the Cashless Policy in Nigeria

Abstract This study makes an analysis of infrastructural challenges and the cashless policy in Kaduna state, Nigeria. A survey was conducted to collect the primary data through a structured questionnaire and interviews with bank customers, bank officials, and security personnel to obtain information on infrastructural challenges since the introduction of the Cashless policy by the Central Bank of Nigeria in 2012. Frequency distribution and simple percentage methods are used to analyze the data. Findings show that infrastructural challenges include network failure and infrastructural deficiency, debiting by Automated Teller Machine (ATM) without disbursing cash to beneficiaries, problems not rectified quickly by the banks, and charging by banks for using electronic banking methods. This leads to fraud, cybercrimes, and reduced confidence in the banking system. It is recommended that banks should be made to provide the minimum infrastructure required for cashless policy to succeed. In addition, there should be adequate cyber security measures implemented by banks and the government.
“Don’t Get Your Meat Where You Get Your Bread”: Beliefs and Advice about Workplace Romance

This investigation identified contemporary beliefs about workplace romance and compared how those beliefs have changed since 1986. Different kinds of advice about workplace romance, and how that advice was related to extant beliefs, were also evaluated. A nationwide sample (N = 259) of organizational members with a variety of professional experiences responded to an anonymous online survey. Results indicated that there were three fundamental underlying beliefs about workplace romance: workplace romance is valuable, the right to demand privacy about workplace romance, and anti-workplace romance. Different types of advice—encouraging, warning, gender concern, and silence—were related to these existing beliefs. The substantial associations between beliefs and advice provide evidence for an implicit theory of workplace romance. Personal experience with such relationships was strongly related to the belief that workplace romance is valuable and the right to demand privacy about workplace romance. Additionally, personal experience was also associated with providing advice promoting workplace romance and advocating that employees should remain silent about engaging in such relationships. These results are discussed within the theoretical lens of boundary blending between the work sphere and the private sphere of social life.
A Predictive Model Based on Inflammatory and Coagulation Indicators for Sepsis-Induced Acute Kidney Injury

Background Sepsis-induced acute kidney injury (S-AKI) is associated with systemic inflammatory responses and coagulation system dysfunction, and it is associated with an increased risk of mortality. However, there was no study to explore the predictive value of inflammatory and coagulation indicators for S-AKI. Methods In this retrospective study, 1051 sepsis patients were identified and divided into a training cohort (75%, n = 787) and a validation cohort (25%, n = 264) in chronological order according to the date they were admitted. Univariate analyses and multivariate logistic regression analyses were performed to identify the independent predictors of S-AKI. The logistic regression analyses (enter methods) were used to conducted the prediction models. The ROC curves were used to determine the predictive value of the constructed models on S-AKI. To test whether the increase in the AUC is significant, we used a two-sided test for ROC curves available online (http://vassarstats.net/roc_comp.html). The secondary outcome was different AKI stages and major adverse kidney events within 30 days (MAKE30). Stage 3B of S-AKI was defined as both meeting the stage 3 criteria [increase of Cr level by > 300% (≥ 4.0 mg/dL with an acute increase of ≥ 0.5 mg/dL) and/or UO < 0.3 mL/kg/h for > 24 h or anuria for > 12 h and/or acute kidney replacement therapy] and having cystatin C positive. MAKE30 were a composite of death, new renal replacement therapy (RRT), or persistent renal dysfunction (PRD). Results We discovered that cardiovascular disease, white blood cell (WBC), mean arterial pressure (MAP), platelet (PLT), serum procalcitonin (PCT), prothrombin time activity (PTA), and thrombin time (TT) were independent predictors for S-AKI. The predictive value (AUC = 0.855) of the simplest model 3 (constructed with PLT, PCT, and PTA), with a sensitivity of 77.6% and a specificity of 82.4%, had a similar predictive value comparing with the model 1 (AUC = 0.872) and the model 2 (AUC = 0.864) in the training cohort (P > 0.05). Compared with the model 1 (AUC = 0.888) and the model 2 (AUC = 0.887), the model 3 (AUC = 0.887) had a similar predictive value in the validation cohort. Moreover, model 3 had the best predictive power for predicting S-AKI in the stage 3 (AUC = 0.777), especially in stage 3B (AUC = 0.771). Finally, the model 3 (AUC = 0.843) had perfect predictive power for predicting MAKE30 in sepsis patients. Conclusion Within 24 hours after admission, the simplest model 3 (constructed with PLT, PCT, and PTA) might be a robust predictor of the S-AKI in sepsis patients, providing information for timely and efficient intervention.
Decentralized User Scheduling and Beamforming in Multi-cell MIMO Networks

We study the problem of distributed user scheduling and beamforming in multi-user, multi-cell, multiple-input multiple-output (MIMO) networks to maximize the weighted sum-rate. While previous work has focused on optimizing the signal-to-leakage-plus noise ratio (SLNR) or the signal-to-interference-plus-noise ratio (SINR), we propose a new signal-to-leakage-plus-interference-plus-noise ratio (SLINR) metric which hybridizes the SINR and SLNR by incorporating the intra-cell interference and inter-cell leakage. Using fractional programming and the Hungarian algorithm, we construct an iterative resource allocator that performs user scheduling and beamforming while accounting for channel estimation errors. Furthermore, we show different approaches for calculating the leakage which vary in terms of practicality and scalability. These approaches decrease the complexity compared to the standard method of leakage calculation, while providing comparable performance. Our results show that resource allocation based on the SLINR metric is a promising solution for decentralized implementation.
Characterization of Transposon-Derived Accessible Chromatin Regions in Rice (Oryza Sativa)

Growing evidence indicates that transposons or transposable elements (TEs)-derived accessible chromatin regions (ACRs) play essential roles in multiple biological processes by interacting with trans-acting factors. However, the function of TE-derived ACRs in the regulation of gene expression in the rice genome has not been well characterized. In this study, we examined the chromatin dynamics in six types of rice tissues and found that ~8% of ACRs were derived from TEs and exhibited distinct levels of accessibility and conservation as compared to those without TEs. TEs exhibited a TE subtype-dependent impact on ACR formation, which can be mediated by changes in the underlying DNA methylation levels. Moreover, we found that tissue-specific TE-derived ACRs might function in the tissue development through the modulation of nearby gene expression. Interestingly, many genes in domestication sweeps were found to overlap with TE-derived ACRs, suggesting their potential functions in the rice domestication. In addition, we found that the expression divergence of 1070 duplicate gene pairs were associated with TE-derived ACRs and had distinct distributions of TEs and ACRs around the transcription start sites (TSSs), which may experience different selection pressures. Thus, our study provides some insights into the biological implications of TE-derived ACRs in the rice genome. Our results imply that these ACRs are likely involved in the regulation of tissue development, rice domestication and functional divergence of duplicated genes.
Conexão e conectividade dos acadêmicos do ensino superior público em Roraima

No século XXI a internet tem se tornado uma tecnologia decisiva na vida das pessoas, principalmente com o advento da comunicação sem fio, gerando o que se pode chamar de “sociedade em rede”. Porém, existe um descompasso entre as pessoas que possuem acesso às tecnologias digitais e à internet, e aquelas que estão na condição de exclusão digital. Com a pandemia causada pelo novo Coronavírus e, consequentemente, com a obrigatoriedade do distanciamento social, o acesso às tecnologias digitais e à internet tornou-se ainda mais necessário. Neste sentido, a partir das definições de conexão e conectividade, este estudo apresenta os resultados de pesquisa realizada com acadêmicos de uma universidade pública do estado de Roraima/Brasil, que verificou a possibilidade e/ou viabilidade da substituição das disciplinas teóricas presenciais por aulas que utilizem meios e tecnologias de informação e comunicação. A pesquisa, de caráter descritivo, com abordagem qualitativa, foi realizada por meio de coleta de dados online, tendo como objetivo conhecer o perfil tecnológico, do ponto de vista de acesso às tecnologias digitais e de conexão e conectividade com a internet dos alunos de graduação e pós-graduação. Os resultados apontam que os acadêmicos entrevistados, de forma geral, possuem acesso aos dispositivos para conexão com a internet, porém, não possuem pacote de dados móveis suficientes para acompanhar aulas por meio de videoconferências. No entanto, a maioria dos acadêmicos entendem que as aulas por meio das tecnologias de comunicação e informação se fazem necessárias, confirmando seu interesse continuar o semestre letivo de forma remota.
Retinal ganglion cell desensitization is mitigated by varying parameter constant excitation pulse trains

Retinal prostheses partially restore vision in patients blinded by retinitis pigmentosa (RP) and age-related macular degeneration (AMD). One issue that limits the effectiveness of retinal stimulation is the desensitization of the retina response to repeated pulses. Rapid fading of percepts is reported in clinical studies. We studied the retinal output evoked by fixed pulse trains vs. pulse trains that have variable parameters pulse-to-pulse. We used the current clamp to record RGC spiking in the isolated mouse retina. Trains of biphasic current pulses at different frequencies and amplitudes were applied. The main results we report are: (1) RGC desensitization was induced by increasing stimulus frequency, but was unrelated to stimulus amplitude. Desensitization persisted when the 20 Hz stimulation pulses were applied to the retinal ganglion cells at 65 μA, 85 μA, and 105 μA. Subsequent pulses in the train evoked fewer spikes. There was no obvious desensitization when 2 Hz stimulation pulse trains were applied. (2) Blocking inhibitory GABAA receptor increased spontaneous activity but did not reduce desensitization. (3) Pulse trains with constant charge or excitation (based on strength-duration curves) but varying pulse width, amplitude, and shape increased the number of evoked spikes/pulse throughout the pulse train. This suggests that retinal desensitization can be partially overcome by introducing variability into each pulse.
Socio-Economic Background of Households and the implication for Housing Choices in Urban Ghana

This study examines the linkages between the socio-economic background of households and their housingchoices in the urban enclaves of Ghana. Multi-stage sampling technique was used to select 900 participantsfrom the study areas. Questionnaire was used to glean data from the participants. Pearson correlation andmultinomial logistic regression were used to estimate the level of association between socio-economiccharacteristics of households and their housing choices. The study found that the choice of housing type wassignificantly associated with sex (χ2=56.004, p<0.001), education level (χ2=238.895, p<0.001), marital status(χ2=28.871, p<0.001), occupation (χ2=202.110, p<0.001), monthly income (χ2=275.682, p<0.001), locationof household (χ2=46.112, p<0.001) but not household size (χ2=18.642, p=0.42), age (χ2=10.229, p=0.113)and religion (χ2=10.361, p=0.110) of the household head. The multinomial logistic regression estimates thathousehold heads with no formal education compared to household heads with master degree are . 055(p<.001) times less likely to live in a detached/semi-detached house compared to compound house. The studyreiterates the importance of having an informed policy on neighbourhood design and development,particularly when designing houses for people of particular socio-economic and cultural backgrounds.
Managing Transference and Countertransference in Cognitive Behavioral Supervision: Theoretical Framework and Clinical Application

Abstract Dysfunctional patterns, beliefs, and assumptions that affect a patient’s perception of other people often affect their perceptions and behaviours towards the therapist. This tendency has been traditionally called transference for its psychoanalytical roots and presents an important factor to monitor and process. In supervision, it is important to put the patient’s transference in the context of the conceptualization of the case. Countertransference occurs when the therapist responds complementary to the patient’s transference based on their own dysfunctional beliefs or assumptions. Transference and countertransference provide useful insights into the inner world of the patient, therapist, and supervisor. Guided discovery is one of the most common approaches used by a supervisor and a supervisee to map all types and directions of transference and countertransference. Other options to map transference and countertransference are imagery and role-playing techniques.
Near-Far Problem based-Game Theory in Device-to-Device Communications

Long Term Evolution (LTE) standardization within the 3GPP has reached a mature state. Device-to-Device communication is a new technology that offer many advantages for the LTE-advanced network such as wireless peer-to-peer services and higher spectral efficiency. In fact, the D2D technologies aim to support the local discovery, identification and to enhance the network capacity and coverage. Near-far problem is one of the major issues that hurts mobile communications inadequately in 6G. This paper proposes a new green power control approach in 6G for a near far system, by modeling it as a non-cooperative game with pure strategies. A non-cooperative game, based on green communications, with statistical strategies is defined, which seek to balance between near and far players (users) belonging to the same Base Station, in terms of allocated power. Two cases are investigated for the proposed game: discrete and continuous, in order to reach both existence and uniqueness of the Nash Equilibrium. Finally, simulations are presented to compare the found results of the proposed games with the classic ones.

Low Rate of Clinically Evident Extravascular Hemolysis in Patients with Paroxysmal Nocturnal Hemoglobinuria Treated with a Complement C5 Inhibitor: Results from a Large, Multicenter, US Real-World Study

Purpose Most patients with paroxysmal nocturnal hemoglobinuria (PNH) treated with a complement protein 5 (C5) inhibitor achieve full control of terminal complement activity and intravascular hemolysis. The minority remains anemic and transfusion dependent despite this control. Etiology for ongoing anemia is multifactorial and includes bone marrow failure, breakthrough hemolysis, extravascular hemolysis (EVH) and nutritional deficiencies. Patients and Methods To evaluate the potential etiologies of hemoglobin levels <10 g/dL despite receiving C5 inhibitor therapy, we performed a retrospective US chart review of adult patients with PNH and treated for at least 12 months with eculizumab (n=53), ravulizumab (n=32), or eculizumab followed by ravulizumab (n=15). Clinically evident EVH was defined as at least one transfusion, reticulocyte count ≥120×109/L and hemoglobin level ≤9.5 g/dL. Safety data were not collected. Mean treatment duration was 26.5±17.2 months. Results Treatment with C5 inhibitors significantly improved hemoglobin, lactate dehydrogenase, and number of transfusions versus baseline. Among the patients with hemoglobin <10 g/dL during the last 6 months of treatment (n=38), one patient (eculizumab) had clinically evident EVH, and 10 patients had active concomitant bone marrow failure. Bone marrow failure was a major contributor to hemoglobin <10 g/dL and transfusion dependence; clinically evident EVH was uncommon. Conclusion A range of hematologic causes need to be considered when evaluating anemia in the presence of treatment with a C5 inhibitor.
Evaluation of the Behavioral and Psychological Symptoms in Patients with Vitiligo in China

Background Vitiligo is a common, acquired depigmenting disorder. The pathogenesis is not clear, neuropsychological factors may be involved. Vitiligo will affect the individual’s physical and psychological health, leading to different levels of psychological behavior problems. However, there are few research on psychological symptoms in patients with vitiligo in China. Methods Adult patients with vitiligo were selected in convenient sampling method from March 2019 to November 2019 from the dermatology clinic. They were evaluated by the DLQI (Dermatology Life Quality Index), SCL-90 (Symptom Checklist-90), SADS (Social Avoidance and Distress Scale) and MCMQ (Medical Coping Modes Questionnaire). Results The DLQI score was 7.56 ± 6.11, which was in the third level. The SCL-90 score of patients with vitiligo was 136.44 ± 39.19, significantly higher than the Chinese norms (P < 0.05), and it mainly manifested as interpersonal sensitivity, depression, anxiety and phobia, which may be affected by the patient’s gender, marital status, severity of disease, stage and location of skin lesions. The total score of SADS in patients was 10.30 ± 6.38. The total score and scores in all dimensions of SADS were significantly higher than the Chinese norms (all P < 0.05), which were related with the patient’s gender, educational attainment, severity, type and stage of skin lesions. For MCMQ, the facing score was significantly lower than the Chinese norms (P < 0.05), and the avoiding and yielding scores were significantly higher than the Chinese norms (all P < 0.05). Conclusion In China, vitiligo affects the patient’s quality of life to varying degrees, resulting in a series of psychological and behavioral problems. We should actively concern and improve the psychological health status and behavior of patients, and multidisciplinary treatment strategies and education about vitiligo should be given to the patients.
