Centralized Cooperative Spectrum Sensing With Mimo In The Reporting Network Over Κ − Μ Fading Channel

Field: Computer Science (Physical Sciences)

The IEEE 802.22 working group aims to drive the
Digital Video Broadcasting-Terrestrial (DVB-T) bands for data
communication to the rural area without interfering the TV broadcast.
In this paper, we arrive at a closed-form expression for average
detection probability of Fusion center (FC) with multiple antenna
over the κ − μ fading channel model. We consider a centralized
cooperative multiple antenna network for reporting. The DVB-T
samples forwarded by the secondary user (SU) were combined using
Maximum ratio combiner at FC, an energy detection is performed
to make the decision. The fading effects of the channel degrades
the detection probability of the FC, a generalized independent and
identically distributed (IID) κ − μ and an additive white Gaussian
noise (AWGN) channel is considered for reporting and sensing
respectively. The proposed system performance is verified through
simulation results.

Professional Life Stress and Coping Strategies Used by House-Job Doctors

Field: Health Professions (Health Sciences)

The current research investigates the relationship between coping strategies and professional life stress reported by house-job doctors. A purposive sample of 200 male and female house-job doctors was drawn from different hospitals in Lahore, Pakistan (Ganga Ram Hospital, Jinnah Hospital, Mayo Hospital, Fatima Memorial Hospital and General Hospital). Coping Orientation to Problem Experienced (COPE) and Professional Life Stress Scale (PLSS) were used to determine the coping strategies and professional life stress, respectively. The findings from the Pearson Product Moment Correlation indicated a significant relationship between; problem-focused coping and stress ( r= -.33, p< .01), emotion-focused coping and stress ( r= .28, p< .01), and avoidance coping and stress ( r= .21, p< .01). The findings from this research have implications for promoting the understanding of the concept of coping strategies and their relationship with professional life stress so that a faculty development program can be introduced for house-job doctors in Pakistan
Garland's method with Banach coefficients

Field: Mathematics (Physical Sciences)

We prove a Banach version of Garland's method of proving vanishing of cohomology for groups acting on simplicial complexes. The novelty of this new version is that our new condition applies to every reflexive Banach space. This new version of Garland's method allows us to deduce several criteria for vanishing of group cohomology with coefficients in several classes of Banach spaces (uniformly curved spaces, Hilbertian spaces and $L^p$ spaces). Using these new criteria, we improve recent results regarding Banach fixed point theorems for random groups in the triangular model and give a sharp lower bound for the conformal dimension of the boundary of such groups. Also, we derive new criteria for group stability with respect to p-Schatten norms.
How To Generate As Many Somos-Like Miracles as You Wish

Field: Mathematics (Physical Sciences)

Jacobi said "man muss immer umkehren". And indeed it takes a genius like Michael Somos to take a specific non-linear recurrence, like a(n)=(a(n-1)a(n-3)+a(n-2)^2)/a(n-4), subject to a(1)=1, a(2)=1, a(3)=1, a(4)=1, and observe that surprise, surprise, they always generate integers. Then it takes other geniuses to actually prove this fact (and the more general so-called Laurent phenomenon). But let's follow Jacobi's advise and go backwards. Rather than try to shoot a target fifty meters away, and most probably miss it, let's shoot first, and then draw the bull'e eye. Then we are guaranteed to be champion target-shooters. So let's take a sequence of integers that manifestly and obviously only consists of integers, and ask our beloved computers to find non-linear recurrences satisfied by the sequence itself, or by well-defined subsequences.
Combined localization and data transmission in energy-constrained wireless sensor networks

Field: Computer Science (Physical Sciences)

Many applications demand simultaneous localization and aggregation in wireless sensor networks. For such an application, e.g. wildlife monitoring, a signaling scheme for a combined localization and communication using a common set of subcarriers is proposed. The concept is based on binary offset carrier signals. But, in contrast to Global Navigation Satellite Systems the presented approach makes use of pure subcarrier localization, and thus enables data transmission in short burst signals. The ranging performance is assessed utilizing the Cramér-Rao Lower Bound depending on the amount of data transferred and considering bit errors.

Yield, varietal zoning of spring barley in Tyumen region and assessment of ecological plasticity and stability of its varieties

Field: Agricultural and Biological Sciences (Life Sciences)

The purpose of the study is to assess the yield of spring barley in the production and state variety testing of the Tyumen region for 2017-2022, its varietal zoning, as well as the yield and adaptability of varieties for 2021-2023 in the conditions of the subtaiga. There was a significant excess of yield in state variety testing compared to production, which averaged 15.0 c/ha in 2017-2022. The originators of most of the varieties approved for use are the Federal Research Centers of the Urals and Western Siberia. The variety Kudesnik (44.8 c/ha) was the best in terms of average yield, and Chelyabinsky 99 (69.2%) – in terms of the realization of its potential. Stress resistance is low in all varieties, which ranged from -31.2 (Orda) to -49.0 (Nord 18/2613). All varieties had significant yield variability, ranging from 42.7% (Orda) to 69.4% (Nord 18/2613). Strong responsiveness to changes in conditions was detected in the varieties KVS Jessy (b i = 1.10) and Nord 18/2613 (b i = 1.34), which are classified as intensive. The varieties Acha, Despina, Kudesnik, Divny and Abba, with a regression coefficient equal to or close to one, were characterized as plastic, and the varieties Orda, Chelyabinsky 99 and Abalak were poorly responsive to changes in conditions (b i < 1). Yield stability is low in all varieties, from St 2 = 0.52 (Nord 18/2613) to St 2 = 0.82 (Abalak, Orda). The variety Kudesnik (E i.. =4.8) was characterized the greatest indicator of the genotypic effect, and the variety Abalak (143.5%) – the indicator of the yield and stability of the variety. The varieties Abalak (sum of ranks 32) and Kudesnik (sum of ranks 35) were recognized as the best by the sum of the ranks of the indicators of yield and adaptability of spring barley for 2021-2023 in the subtype of the Tyumen region.
Does social thermal regulation constrain individual thermal tolerance in an ant species?

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract In ants, social thermal regulation is the collective maintenance of a nest temperature that is optimal for individual colony members. In the thermophilic ant Aphaenogaster iberica , two key behaviours regulate nest temperature: seasonal nest relocation and variable nest depth. Outside the nest, foragers must adapt their activity to avoid temperatures that exceed their thermal limits. It has been suggested that social thermal regulation constrains physiological and morphological thermal adaptations at the individual level. We tested this hypothesis by examining the foraging rhythms of six populations of A. iberica , which were found at different elevations (from 100 to 2,000 m) in the Sierra Nevada mountain range of southern Spain. We tested the thermal resistance of individuals from these populations under controlled conditions. Janzen's climatic variability hypothesis (CVH) states that greater climatic variability should select for organisms with broader temperature tolerances. We found that the A . iberica population at 1,300 m experienced the most extreme temperatures and that ants from this population had the highest heat tolerance (LT50 = 57.55°C). These results support CVH's validity at microclimatic scales, such as the one represented by the elevational gradient in this study. Aphaenogaster iberica maintains colony food intake levels across different elevations and mean daily temperatures by shifting its rhythm of activity. This efficient colony‐level thermal regulation and the significant differences in individual heat tolerance that we observed among the populations suggest that behaviourally controlled thermal regulation does not constrain individual physiological adaptations for coping with extreme temperatures.

The soluble aluminum compounds and nanocomposite materials based on them. Part I.

Field: Chemistry (Physical Sciences)

Simple aluminum compounds are precursors for all processes for the production of nanocomposite materials based on aluminum oxides. The present work analyzes the state of Al3+ aluminum ions in aqueous solutions. The state of Al3+ ions in aqueous solutions determines the mechanism and structure of the produced nanocomposites. The analysis of phase transformations in systems of aluminum salts, hydrated oxides and oxides is carried out. The main conditions to obtain final materials are determined on the basis on these data. An analysis of various methods used to prepare colloidal solutions of hydrated aluminum oxides has been performed. Such solutions are the main precursors in the production of nanocomposite materials based on aluminum oxides. The processes of obtaining alumina-sol by precipitation-peptization method which is one of the main methods were investigated. For the synthesis of alumina-sol, the possibilities of using ion exchange methods and controlled hydrolysis of aluminum compounds have also been considered. Analysis of the silica-sol and alumina-sol interaction processes was conducted to obtain a mixed oxide material in the system SiO2–Al2O3. The possibility of applying homogeneous precipitation of hydrated alumina to prepare nanocomposites based on aluminum oxide has been studied.

Juggling Between Paperwork and Patient Care: How Residents View Their Time Division in Clinical Training?

Field: Health Professions (Health Sciences)

Objective: The objective of this study was to explore residents’ perception of time they spend on clinical data and patient care. Methods: A cross-sectional study, utilizing a validated questionnaire was conducted in July 2019 at the King Fahad Armed Forces Hospital, Jeddah after gaining ethical approval. Link to the online survey designed on Google forms was shared through Facebook, WhatsApp, and Email. The questionnaire consisted of 21 items to assess different variables like direct patient care, documentation requirements, and complete patient interaction. Results: Out of 150 participants, the response rate was 111 (74%). Of 111 participants, regarding clinical documentation, 105 (95%) felt that it has become excessive, and 93 (84%) agreed that it compromises patient time. In addition, 87 (78%) residents felt rushed all the time and 82 (74%) said that they are frustrated with data entry. On the educational value of clinical documentation, 90 (81%) of residents agreed that it has little or no influence. Furthermore, 92 (83%) agreed that it negatively impacts the time available for teaching other junior residents. Conclusion: We conclude that: although residents wish to provide quality care to their patients, many of them felt that data entry has become excessive and it is negatively affecting their clinical training.
Genetic Characteristics and Clonal Dissemination of β-Lactamase-Negative Ampicillin-ResistantHaemophilus influenzaeStrains Isolated from the Upper Respiratory Tract of Patients in Japan

Field: Medicine (Health Sciences)

ABSTRACT We evaluated the recent prevalence of antimicrobial-resistant Haemophilus influenzae isolated from the upper respiratory tracts (URT) of patients in Japan. Mutations in the ftsI gene, which encodes penicillin binding protein 3 (PBP3), and the clonal dissemination of the resistant strains were also investigated. A total of 264 H. influenzae isolates were collected from patients with URT infections. According to the criteria of the Clinical and Laboratory Standards Institute for the susceptibility of H. influenzae to ampicillin (AMP), the isolates were distributed as follows: 161 (61.0%) susceptible strains (MIC ≤ 1 μg/ml), 37 (14.0%) intermediately resistant strains (MIC = 2 μg/ml), and 66 (25.0%) resistant strains (MIC ≥ 4 μg/ml). According to PCR-based genotyping, 172 (65.1%) of the isolates had mutations in the ftsI gene and were negative for the β-lactamase ( bla ) gene. These 172 isolates were thus defined as genetically β-lactamase-negative ampicillin-resistant (gBLNAR) strains. The ftsI mutant group included 98 (37.1%) strains with group I/II mutations in the variable mutated region (group I/II gBLNAR) and 74 (28.0%) strains with group III mutations in the highly mutated region (group III gBLNAR). Eighty-seven (33.0%) of the isolates were genetically β-lactamase-negative ampicillin-susceptible (gBLNAS) strains. The group III gBLNAR strains showed resistance to β-lactams. Only five strains (1.9%) were positive for a bla gene encoding TEM-type β-lactamase. The three clusters consisting of 16 strains found among the 61 BLNAR strains (MIC ≥ 4 μg/ml and without the bla gene) showed identical or closely related DNA restriction fragment patterns. Those isolates were frequently identified among strains with a MIC to AMP of 16 μg/ml. The current study demonstrates the apparent dissemination and spread of a resistant clone of H. influenzae among medical centers in Japan. The gBLNAR strains show a remarkable prevalence among H. influenzae isolates, with the prevalence increasing with time. This fact should be taken into account when treating URT infections.

Semitopological modules

Field: Mathematics (Physical Sciences)

Given a topological ring $R$, we study semitopological $R$-modules, construct their completions, Bohr and borno modifications. For every topological space $X$, we construct the free (semi)topological $R$-module over $X$ and prove that for a $k$-space $X$ its free semitopological $R$-module is a topological $R$-module. Also we construct a Tychonoff space $X$ whose free semitopological $R$-module is not a topological $R$-module.
Hybridization with <i>Fagopyrum cymosum</i> Meisn. as a way to make cultivated Tartary buckwheat (<i>F. tataricum</i> Gaertn.) with grain characteristics typical for common buckwheat (<i>F. esculentum</i> Moench.)

Field: Agricultural and Biological Sciences (Life Sciences)

Compared to common buckwheat (F. esculentum), Tartary buckwheat (F. tataricum) is very polymorphic in the type of seeds, but a seed type which is typical for F. esculentum, i.e. triangular seeds with flat sides and clear ribs, has been not found among the polymorphism. However, such seed type is typical for wild species F. cymosum which produces fertile hybrids in crosses with F. tataricum. Embryo rescue based interspecific cross F. esculentum × F. cymosum allowed reveal functional allelism of the genes determining the similar morphs of these species' seeds, i.e. the seed type resulted from mutation(s) at same gene. The gene can be assigned as TAN (triangular). Variation for the seed shell thickness among recessives for the TAN carrying about 12% of F. tataricum genome, together with the shell thickness of a seed from the F1 hybrid F. esculentum × F. cymosum compared to ones of the parents, suggests there are some genes influencing seed shell thickness. Also, it was supported by analyses of seeds characteristics of Tartary-based forms with some share of F. cymosum genetic material. In addition, cross F. tataricum × F. cymosum looks like an effective tool to increase 1000-seed weight of Tartary buckwheat-based breeding material.
Insufficient physical activity and high sedentary behaviour are associated with loneliness in adolescents with overweight/obesity: Evidence from 23 low‐ and middle‐income countries

Field: Medicine (Health Sciences)

Summary Background/Objectives Overweight and obesity among young people is a major concern with implications for social wellbeing. We aimed to evaluate the associations of physical activity (PA) and sedentary behaviour (SB) with loneliness among adolescents with overweight/obesity. Methods Data were used from the Global School‐based Student Health Surveys, collected from 23 low‐and‐middle‐income countries. Results Of the 12,133 participants aged 12–17 years with overweight/obesity (48.4% girls), 12% were lonely, with a wide variation across countries ranging from 4% in Laos to 32% in Afghanistan. Overall, 31% had high SB (≥3 hours/day) and 86% were not sufficiently active (<7 days/week of ≥ 60 mins/day). High SB and insufficient PA were positively associated with loneliness (aOR 1.22, 95% CI 1.08–1.38, aOR 1.37, 95% CI 1.18–1.59, respectively). Conclusions Future research could examine the direction of these relationships and evaluate strategies to optimise these indicators of social wellbeing among adolescents with overweight/obesity.
