Fitted function to rotation curve

This paper develops carefully an original theory of dark matter, whose main hypothesis is that DM is generated by the own gravitational field. This work introduces the best version of the theory physical and mathematically, which has been developed and published since 2013. The hypothesis of DM by gravitation has two main consequences: the first one is that the law of DM generation has to be the same, in the halo region, for all the galaxies and the second one is that the haloes are unlimited so the total DM goes up without limit. Both properties are crucial for the success of this theory. This work has two newness: it is demonstrate that Direct mass comes from Bernoulli mass formula when it is considered an initial point belonging to the Buckingham halo curve, (ideal curve related to dynamical equilibrium), to calculate the parameter C. The second one is two astonishing calculus of masses in LG. This work begins studying the Rotation curves, from M31 and MW, published by Sofue,Y.2015 and 2020 . The regression curves at halo region are fitted with power regression functions whose exponents are the same for both galaxies.

Lipids in Health and Disease

Background: Lipoprotein-associated phospholipase A2 (Lp-PLA2) also known as serum platelet activating factor acetylhydrolase (PAF-AH) activity constitutes a novel risk marker for cardiovascular disease. Leukocytes constitute one main cellular source of circulating Lp-PLA2. The aim of the present study was to evaluate the association of both serum and leukocyte PAF-AH activities with fat distribution and lean tissue. One hundred healthy volunteers without cardiovascular disease history participated in this study (n = 52 men, 44 ± 13 years and n = 48 women, 43 ± 13 years). Body composition was assessed with dualenergy X-ray absorptiometry, while anthropometrical indices were also measured. The activity of Lp-PLA2 and levels of lipid and glycemic parameters were determined in fasting samples. Results: Mean Lp-PLA2 activity was 24.8 ± 4.5 and 19.6 ± 5.0 nmol/min/mL in men and women, respectively (P < 0.001). Mean activity of PAF-AH in leukocyte homogenates was 386 ± 127 pmol/min/mg and 292 ± 92 pmol/min/mg in men and women, correspondingly (P < 0.001). In multiple regression models upper and total adiposity measures were positively associated with Lp-PLA2 activity in men after adjusting for LDL-cholesterol, age, smoking, hs-CRP and physical activity, whereas no associations were found with PAF-AH leukocyte homogenates activity. Hierarchical analysis revealed that the variables with the highest explanatory ability of Lp-PLA2 activity in men, were DXA deriving L1–L4 region of interest and arms fat (increase in R2 = 0.136, P = 0.005 and increase in R2 = 0.118, P = 0.009, respectively), followed by trunk fat and total fat. In women, no association of body composition variables with Lp-PLA2 nor PAF-AH leukocyte homogenates activity was found. Conclusion: Lp-PLA2 activity is differentiated across levels of adiposity and topology of adipose tissue, whereas no association was found regarding PAF-AH leukocyte homogenates activity. Our findings suggest that Lp-PLA2 may compensate for the adiposity-associated increases in inflammatory and oxidative burden, in men.

Lipids in Health and Disease

Objective: In this work we evaluated the 5-year incidence of hypercholesterolemia, in a sample of cardiovascular disease free adult men and women from Greece. We also evaluated the association of several socio-demographic, dietary and lifestyle habits on the incidence of this disorder. Methods: 1514 men and 1528 women (>18 y) without any clinical evidence of cardiovascular disease, living in Attica area, Greece, were enrolled in the ATTICA study from May 2001 to December 2002. The sampling was random, multi-stage, and included information about various socio-demographic, lifestyle (diet, exercise, smoking etc), biological (lipids, and inflammatory markers), and clinical characteristics of the participants. In 2006, a group of experts performed the 5-year follow-up through telephone calls or personal visits (941 of the 3042 (31%) participants were lost to follow-up). Hypercholesterolemia, among people who had normal blood lipids at initial examination, was defined as fasting total cholesterol levels > 200 mg/dl or use of lipids lowering agents (NCEP ATPIII). Results: The 5-year incidence of hypercholesterolemia was 23.7% (n = 127) in men and 17.7% (n = 110) in women (p for gender differences < 0.001). Multi-adjusted logistic regression analysis which revealed that increased age (odds ratio = 1.05, p < 0.001), waist circumference (odds ratio = 1.02, p = 0.03), fasting blood glucose (odds ratio = 1.01, p = 0.08) and apolipoprotein B (odds ratio = 1.02, p = 0.001) levels, were the most significant baseline predictors of developing hypercholesterolemia within a 5-year period. Conclusion: Incidence of hypercholesterolemia was high in both genders, emphasizing the burden of this disorder at population level. Aging, increased waist circumference, fasting blood glucose and apolipoprotein B levels were the most significant baseline predictors of hypercholesterolemia.

A Comparative Study of Machine Learning and Deep Learning Algorithms for Speech Emotion Recognition

—Today’s world has been "Chatting" with machines for a long time . Speech signal processing has been a long-standing topic of discussion, and its applications in our lives have been evolving over time. One of these applications is speech emotion recognition. Which is the process of identifying the emotions expressed in a person's speech. This is a challenging task, as emotions are subjective and can be expressed differently by different people. Emotions are difficult to categorize because there is no single set of criteria or steps that everyone agrees on. This paper compares four methods used to recognize emotion from speech. The comparison is mainly done on the IEMOCAP dataset, which is a large and well-annotated emotional speech dataset.
Creating Binary Cu − Bi Compounds via High-Pressure Synthesis: A Combined Experimental and Theoretical Study

: Exploration beyond the known phase space of thermodynamically stable compounds into the realm of metastable materials is a frontier of materials chemistry. The application of high pressure in experiment and theory provides a powerful vector by which to explore this uncharted phase space, allowing discovery of complex new structures and bonding in the solid state. We harnessed this approach for the Cu − Bi system, where the realization of new phases o ﬀ ers potential for exotic properties such as superconductivity. This potential is due to the presence of bismuth, which, by virtue of its status as one of the heaviest stable elements, forms a critical component in emergent materials such as superconductors and topological insulators. To fully investigate and understand the Cu − Bi system, we welded theoretical predictions with experiment to probe the Cu − Bi system under high pressures. By employing the powerful approach of in situ X-ray di ﬀ raction in a laser-heated diamond anvil cell (LHDAC), we thoroughly explored the high-pressure and high-temperature (high-PT ) phase space to gain insight into the formation of intermetallic compounds at these conditions. We employed density functional theory (DFT) calculations to calculate a pressure versus temperature phase diagram, which correctly predicts that CuBi is stabilized at lower pressures than Cu 11 Bi 7 , and allows us to uncover the thermodynamic contributions responsible for the stability of each phase. Detailed comparisons between the NiAs structure type and the two high-pressure Cu − Bi phases, Cu 11 Bi 7 and CuBi, reveal the preference for elemental segregation within the Cu − Bi phases, and highlight the unique channels and layers formed by ordered Cu vacancies. The electron localization function from DFT calculations account for the presence of these “ voids ” as a manifestation of the lone pair orientation on the Bi atoms. Our study demonstrates the power of joint experimental − computational work in exploring the chemistry occurring at high-PT conditions. The existence of multiple high-pressure-stabilized phases in the Cu − Bi binary system, which can be readily identi ﬁ ed with in situ techniques, o ﬀ ers promise for other systems in which no ambient pressure phases are known to exist.

— A dream of humanoid robot researchers is to develop a complete “human-like” (whatever that means) artificial agent both in terms of body and brain. We now have seen an increasing number of humanoid robots (such as Honda’s ASIMO, Aldebaran’s Nao and many others). These, however, display only a limited number of cognitive skills in terms of perception, learning and decision-making. On the other hand, brain research has begun to produce computational models such as LIDA. In this paper, we propose an intermediate approach for body-brain integration in a form of a scenario-based distributed system. Busy hospital Emergency Departments (ED) are concerned with shortening the waiting times of patients, with relieving overburdened triage team physicians, nurses and medics, and with reducing the number of mistakes. Here we propose a system of cognitive robots and a supervisor, dubbed the TriageBot System that would gather both logistical and medical information, as well as take diagnostic measurements, from an incoming patient for later use by the triage team. TriageBot would also give tentative, possible diagnoses to the triage nurse, along with recommendations for non-physician care Some of the robots in the TriageBot System would be humanoid in form, but it is not necessary that all of them take this form. Advances in humanoid robotic design, in sensor technology, and in cognitive control architectures make such a system feasible, at least in principle.
A protocol for systematic review and meta-analysis

Background: In recent years, with the accelerated pace of life, diet, environmental problems occur frequently. External factors are easily to cause endocrine disorders and hormone sensitivity of breast tissue, which can lead to mammary hyperplasia. The incidence rate of hyperplasia of mammary glands is increasing year by year, and the age of onset is also getting lower and lower. If not treated in time, there is a crisis of breast cancer. Clinical studies have found that auricular point pressing therapy is widely used in clinical treatment of mammary hyperplasia recently, but the efficacy of massage in the treatment of mammary hyperplasia has not been systematically reviewed. The purpose of this study is to explore the efficacy, safety and effectiveness of auricular point pressing therapy in the treatment of hyperplasia of mammary glands. Methods:We will search PubMed, Web of Science, Cochrane Library, EMBASE, Wan fang Database, Chinese Scientific Journal Database, CNKI, VIP, and Chinese Biomedical Literature Database. The retrieval date was January 10, 2021. RevMan 5.3 software was used to evaluate the quality and risk of included studies. The efficacy, recurrence rate, and symptom score of breast hyperplasia were analyzed, and the results were observed and measured. Results: This study will be from the clinical efficiency, improvement rate, pain symptoms disappear rate, tumor size improvement rate, and other aspects of the existing evidence for a high quality synthesis, as well as auricular point pressing therapy adverse events. Conclusion: the conclusion of this review will provide the basis for judging whether auricular point pressing therapy is safe and effective in the treatment of hyperplasia of mammary glands. Ethics and dissemination: This systematic will evaluate the effectiveness and safety of auricular point pressing therapy in the treatment of hyperplasia of mammary glands. As all data used in this systematic review and meta-analysis have been published, ethical approval is not required for this review. Protocol registration number: INPLASY202110028. Abbreviation: RCT = randomized controlled trial.
Looking Back, Looking Forward

The purpose of the study was to understand faculty career values and how faculty values and priorities were affected by COVID-19. Using a mixed-method design, this study found there were differences among the relative value faculty placed on research, teaching, and service, and these differences were consistent with expectations for faculty employed in various tenure and non-tenure line positions. In some instances, faculty values remained the same. In others, the faculty statements indicated changed values in the domains of faculty self-direction and sense of security, the former associated with work-life balance and burnout and the latter with salary and retirement concerns. This study provided insight into faculty values and priorities and how those values and priorities may have changed because of the pandemic. These understandings of faculty values and experiences have implications for faculty recruitment, retention, and development.
The interaction of compliance and activation on the force-length operating range and force generating capacity of skeletal muscle

Muscle performance is influenced by where it operates on its force-length curve. Here we explore how activation and tendon compliance interact to influence muscle operating lengths and force-generating capacity. To study this, we built a musculoskeletal model of the lower limb of the guinea fowl and simulated the force-length operating range during fixed-end fixed-posture contractions for 39 actuators under thousands of combinations of activation and posture using three different muscle models: Muscles with non-compliant tendons, muscles with compliant tendons but no activation dependent shift in optimal fiber length (L0), and muscles with both compliant tendons and activation-dependent shifts in L0. We found that activation dependent effects altered muscle fiber lengths up to 40% and increased or decreased force capacity by up to 50% during fixed-end contractions. Typically, activation-compliance effects reduce muscle force and are dominated by the effects of tendon compliance at high activations. At low activation, however, activation-dependent shifts in L0 are equally important and can result in relative force changes for low compliance muscles of up to 60%. There are regions of the force-length curve in which muscles are most sensitive to compliance and there are troughs of influence where these factors have little effect. These regions are hard to predict, though, because the magnitude and location of these areas of high and low sensitivity shift with compliance level. Here we provide a map for when these effects will meaningfully influence force capacity and an example of their contributions to force production during a static task, namely standing.
Integrative Biology

Synopsis Pygopodids are elongate, functionally limbless geckos found throughout Australia. The clade presents low taxonomic diversity ( (cid:2) 45 spp. ), but a variety of cranial morphologies, habitat use, and locomotor abilities that vary between and within genera. In order to assess potential relationships between cranial morphology and ecology, computed tomography scans of 29 species were used for 3D geometric morphometric analysis. A combination of 24 static landmarks and 20 sliding semi-landmarks were subjected to Generalized Procrustes Alignment. Disparity in cranial shape was visualized through Principal Component Analysis, and a multivariate analysis of variance (MANOVA) was used to test for an association between shape, habitat, and diet. A subset of 27 species with well-resolved phylogenetic relationships was used to generate a phylomorphospace and conduct phylogeny-corrected MANOVA. Similar analyses were done solely on Aprasia taxa to explore species-level variation. Most of the variation across pygopodids was described by principal component (PC) 1(54%: cranial roof width, parabasisphenoid, and occipital length), PC2 (12%: snout elongation and braincase width), and PC3 (6%: elongation and shape of the palate and rostrum). Without phylogenetic correction, both habitat and diet were significant influencers of variation in cranial morphology. However, in the phylogeny-corrected MANOVA, habitat remained weakly significant, but not diet, which can be explained by generic-level differences in ecology rather than among species. Our results demonstrate that at higher levels, phylogeny has a strong effect on morphology, but that influence may be due to small sample size when comparing genera. However, because some closely related taxa occupy distant regions of morphospace, diverging diets, and use of fossorial habitats may contribute to variation seen in these geckos.
Satellite measurements of the global mesospheric sodium layer

Optimal estimation theory is used to retrieve the absolute Na density profiles in the mesosphere/lower thermosphere from limb-scanning measurements of the Na radiance at 589 nm in the dayglow. Two years of observations (2003 and 2004), recorded by the OSIRIS spectrometer on the Odin satellite, have been analysed to yield the seasonal and latitudinal variation of the Na layer column abundance, peak height, and peak width. The layer shows little seasonal variation at low latitudes, but the winter/summer ratio increases from a factor of ~3 at mid-latitudes to ~10 in the polar regions. Comparison of the measurements made at about 06:00 and 18:00 LT shows little diurnal variation in the layer, apart from the equatorial region where, during the equinoxes, there is a two-fold increase in Na density below 94 km between morning and evening. This is most likely caused by the strong downward wind produced by the diurnal tide between ~02:00 and 10:00 LT. The dramatic removal of Na below 85 km at latitudes above 50° during summer is explained by the uptake of sodium species on the ice surfaces of polar mesospheric clouds, which were simultaneously observed by the Odin satellite.
Intermittent supplementation with fisetin improves arterial function in old mice by decreasing cellular senescence

Abstract Cellular senescence and the senescence‐associated secretory phenotype (SASP) contribute to age‐related arterial dysfunction, in part, by promoting oxidative stress and inflammation, which reduce the bioavailability of the vasodilatory molecule nitric oxide (NO). In the present study, we assessed the efficacy of fisetin, a natural compound, as a senolytic to reduce vascular cell senescence and SASP factors and improve arterial function in old mice. We found that fisetin decreased cellular senescence in human endothelial cell culture. In old mice, vascular cell senescence and SASP‐related inflammation were lower 1 week after the final dose of oral intermittent (1 week on—2 weeks off—1 weeks on dosing) fisetin supplementation. Old fisetin‐supplemented mice had higher endothelial function. Leveraging old p16‐3MR mice, a transgenic model allowing genetic clearance of p16INK4A‐positive senescent cells, we found that ex vivo removal of senescent cells from arteries isolated from vehicle‐ but not fisetin‐treated mice increased endothelium‐dependent dilation, demonstrating that fisetin improved endothelial function through senolysis. Enhanced endothelial function with fisetin was mediated by increased NO bioavailability and reduced cellular‐ and mitochondrial‐related oxidative stress. Arterial stiffness was lower in fisetin‐treated mice. Ex vivo genetic senolysis in aorta rings from p16‐3MR mice did not further reduce mechanical wall stiffness in fisetin‐treated mice, demonstrating lower arterial stiffness after fisetin was due to senolysis. Lower arterial stiffness with fisetin was accompanied by favorable arterial wall remodeling. The findings from this study identify fisetin as promising therapy for clinical translation to target excess cell senescence to treat age‐related arterial dysfunction.
Individual effects of GSTM1 and GSTT1 polymorphisms on the risk of polycystic ovarian syndrome: A systematic review and meta-analysis

This study aimed to understand the relationship between two specific genetic variations (GSTT1 and GSTM1 polymorphisms) and the risk of developing polycystic ovarian syndrome (PCOS). PCOS is a common endocrinologic disorder that affects women. Oxidative stress may play a significant role in the development of PCOS. Certain enzymes, such as glutathione S-transferases, help protect cells against oxidative stress. However, previous research on the correlation between these specific genetic variations and PCOS risk has produced inconsistent findings. To address this, a meta-analysis was conducted to examine the potential impact of these genetic variations on PCOS. We conducted a thorough search of the Embase, PubMed, Scopus, Web of Science, and Google Scholar databases to find studies that met our criteria. We used fixed-effects or random-effects models to determine the pooled odds ratios (ORs) and 95% confidence intervals (CIs) of the GSTT1 and GSTM1 polymorphisms related to PCOS. We also performed subgroup analyses based on ethnicity, mean age of participants, and PCOS diagnostic protocols. After screening, we found five studies with 1.607 participants (872 in the PCOS group and 735 in the control group) to be suitable for our meta-analysis. Our analysis showed that GSTM1 and GSTT1 null genotypes were not linked to an increased risk of PCOS (OR: 0.925, 95% CI: 0.755-1.134; OR: 1.175, 95% CI: 0.614-2.247 respectively). Additionally, both Begg’s and Egger’s tests revealed no publishing bias. This meta-analysis confirmed that there is no association between GSTM1 and GSTT1 polymorphisms and an increased risk of PCOS. However, further studies are required to validate this conclusion.
