A STATISTICAL ANALYSIS OF THE LATE-TYPE STELLAR CONTENT IN THE ANDROMEDA HALO

We present a statistical characterization of the carbon-star to M-giant (C/M) ratio in the halo of M31. Based on the application of pseudo-filter bandpasses to our Keck/DEIMOS spectra, we measure the 81 − 77 color index of 1288 stars in the giant stellar stream and in halo fields out to large distances. From this well-established narrow-band system, supplemented by V − I colors, we find only a low number (five in total) of C-star candidates. The resulting low C/M ratio of 10% is consistent with the values in the M31 disk and inner halo from the literature. Although our analysis is challenged by small number statistics and our sample selection, there is an indication that the oxygen-rich M-giants occur in similar number throughout the entire halo. We also find no difference in the C-star population of the halo fields compared to the giant stream. The very low C/M ratio is at odds with the observed low metallicities and the presence of intermediate-age stars at large radii. Our observed absence of a substantial carbon-star population in these regions indicates that the (outer) M31 halo cannot be dominated by the debris of disk-like or Small-Magellanic-Cloud-type galaxies, but rather resemble the dwarf elliptical NGC 147.
Enhancement of curcumin level and hepatoprotective effect in rats through antioxidant activity following modification into nanosized particles

Background and Aim: Developing curcumin into nanosized particles is one of the approaches to overcome the limited use of curcumin. This study aimed to prepare curcumin into nanosized particles to increase the curcumin level in the rat’s liver and hepatoprotective effect in rats. Materials and Methods: Curcumin into nanosized particles formulated using ionic gelation method. Rats were divided into four groups (n = 6): Normal, negative, curcumin, and curcumin modified into nanosized particles were treated with 100 mg/kg body weight orally for 14 days. Hepatic curcumin level was investigated using liquid chromatography with tandem mass spectrometry, antioxidant activity by malondialdehyde (MDA), and hepatoprotective effect by aspartate transaminase (AST), alanine transaminase (ALT), and histopathology. Results: The curcumin level in the rat’s liver in the curcumin group was 12.19 ng/mL, and that in those receiving modified into nanosized curcumin was 209.36 ng/mL. The MDA levels in the normal, negative, curcumin, and curcumin modified into nanosized particles groups were 1.88, 4.87, 3.38, and 1.04 nmol/L, respectively. The AST levels in these groups were 57.12, 130.00, 102.13, and 74.28 IU/L, and the ALT levels were 21.63, 61.97, 39.38, and 28.55 IU/L. The liver histopathology scoring showed that curcumin in nanosized particles was better than curcumin in degeneration of fat, lymphocyte infiltration, and necrosis. Conclusion: There was a 17 times increase in curcumin level in the liver of rats treated with curcumin modified into nanosized particles. Curcumin modified into nanosized particles showed more significant improvement as antioxidant and hepatoprotector than curcumin.
Therapeutic potentials associated with biological properties of Juniper berry oil (Juniperus communis L.) and its therapeutic use in several diseases – A Review

Juniperus communis L. is a plant that belongs to the Cupressaceae family. It grows as either a shrub or small tree and is widely distributed across the Northern Hemisphere, including northern Europe, Asia, and America. The berries are an efficient source of several bioactive structures. This review article will focus on the current status of the therapeutic use of juniper berry essential oil, which is presently indicated as a herbal medicinal treatment for dyspepsia. Interest in plant-based medicinal products is growing, and therefore it is important that accessible, up-to-date research is available to patients. Many plants are a natural source of therapeutic structures and can therefore often provide an alternative to synthetic pharmacology. A main constituent of juniper berry oil is α-pinene, a highly active structure which has been shown in in vitro and in vivo studies to possess several biological activities. This review sums up the available reports and indications which describe the function and value of juniper berry essential oil and especially, the constituent α-pinene as a potential candidate in several disorders and inflammatory conditions.Keywords: Juniperus communis, dyspepsia, juniper berry oil, Antioxidant activity, Antibacterial activity, Anti-inflammatory activity
Low-Temperature Quasi-Equilibrium States in the Hydrogen Atom

The dynamics of the approach to equilibrium of the hydrogen atom is investigated numerically through a Monte Carlo procedure. We show that, before approaching ionization, the hydrogen atom may live in a quasi-equilibrium state, characterized by aging, whose duration increases exponentially as the temperatures decreases. By analyzing the quasi-equilibrium state, we compute averages of physical quantities for the hydrogen atom. We have introduced an analytic approach that fits satisfactorily the numerical estimates for low temperatures. Although the present analysis is expected to hold for energies typically up to 6% of the ionization energy, it works well for temperatures as high as 10^{4} K.
Unicorns on the Digital Range: Bisexual Persons’ Experiences of Geo-Social Networking Application Use

Abstract Geo-social networking applications (GSNAs) like Tinder and Grindr are popular tools for connecting with people for romance, sex, and other purposes, particularly among sexual minorities. This paper draws on narrative interviews with 13 bisexual persons (5 cisgender men, 6 cisgender women, 2 trans/nonbinary persons) to explore their GSNA use, including motives and gratifications, relational dynamics, and implications for individual identities and cultural understandings of bisexuality. Participants presented complex and ambivalent accounts of their GSNA use, revealing a variety of relational aspirations and experiences. Whatever users’ goals, cultural meanings associated with bisexuality shaped online interactions in ways that impeded their fulfillment, with binegativity routinely preventing relationship formation in the first instance or precipitating relationship dissolution. Despite these challenges, bisexual persons regularly have successful digitally-mediated encounters which can reshape private and collective understandings of bisexuality. GSNAs expose users to new experiences and discourses that help them make sense of their erotic predilections, including partner sex/gender sexuality. They may also play a role in the broader sea change in attitudes toward bisexuality by facilitating the formation of mixed orientation relationships wherein stereotypes are gradually replaced by direct personal experience.
The factors affecting sexual satisfaction and sexual myths in married women: A prospective study

Aim: The cultural differences and taboos of the society affect women’s sexual life and sexual relationship qualities and their belief in sexual myths. In addition, women’s demographic characteristics and living conditions are also effective on sexual myths. Our aim in this study is to analyze the frequency of believing in sexual myths in married women and to examine the factors affecting sexual life and sexual relationship qualities. Material and Method: Married women between the ages of 18-55 in the tertiary gynecology and obstetrics clinic were included in the study, prospectively. Demographic characteristics of women such as age, marital status, marriage and employment status, monthly income, family structure and number of children, sexual life and sexual relationship qualities and sexual myths were compared. The Golombok-Rust Inventory of Sexual Satisfaction (GRISS) Scale, which is used to evaluate the quality of sexual intercourse and sexual dysfunctions, and The Sexual Myth Scale to determine the status of having sexual myths were used. Results: Overall 171 married women were included in the study. The median age was 35 years (IQR 29-43) and 60.8% (n=104) were university graduates and 20.5% (n=35) were graduate/doctoral graduates. The rate of believing in sexual myths among married women was 21.4%. As the age of the women increased, the frequency of sexual intercourse decreased (p
Roles of free radicals in reproduction and immune modulations in goats: A review

In the body physiology, gonads (i.e. testes and ovaries) and lymphoid organs are most important tissues in terms of metabolism and dynamicity as functional activities of lymphoid organ and gonad are multistep and energy consuming processes they are always performing a number of biochemical reactions. As a causative effect of the same generation of free radicals are quite obvious. Thus, enormous production of free radicals can limit the proper functional management of lymphoid organ and gonad. We noted significantly high levels of SOD, Catalase, GPx activities and ABTS levels in lymphoid organs and gonads of goats during monsoon and significantly low during winter particularly in lymphoid organs. However, all the parameters were significantly high in gonads during winter only. Malonaldihyde; MDA a marker for lipid peroxidation presented a reverse pattern of activity level than SOD being significantly high during summer but the level was significantly low during monsoon and winter. The glucocorticoid receptor expression was significantly high in spleen and thymus of males during monsoon but the level was significantly high only during monsoon in lymphoid organs of males. All the free radical parameters cumulatively suggest that, monsoon and winter are the seasons of stress for both the sexes of goats as suggested by elevated level of glucocorticoid receptor and thus to counteract the elevated stress level melatonin acted as a “coupler” which not only increased the free radical scavenging enzymes but also scavenged free radicals as an amphipatic free molecules particularly during winter. Winter is the most challenging season for female goats due to “cold stress” as well as “gestational stress” along with energy demanding mega two major events i.e. Maintenance of immunity and gestation is occurring simultaneously.
Unsupervised Domain Adaptation for Crime Risk Prediction Across Cities

Crime risk prediction is crucial for city safety and residents’ life quality. However, without labeled data, it is challenging to predict crime risk in cities. Due to municipal regulations and maintenance costs, it is not trivial for many cities to collect high-quality labeled crime data. In particular, some cities have lots of labeled data while others may have few. It has been possible to develop a crime prediction model for a city without labeled crime data by learning knowledge from a city with abundant data. Nevertheless, the inconsistency of relevant context data between cities exacerbates the difficulty of this prediction task. To this end, this article proposes an effective unsupervised domain adaptation model (UDAC) for crime risk prediction across cities while addressing the contexts’ inconsistency issue. More specifically, we first identify several similar source city grids for each target city grid. Based on these source city grids, we then construct auxiliary contexts for the target city, to make contexts consistent between the two cities. A dense convolutional network with unsupervised domain adaptation is designed to learn high-level representations for accurate crime risk prediction and simultaneously learn domain-invariant features for domain adaptation. The effectiveness of our model is verified through extensive experiments using three real-world datasets.
Statistical Topics Concerning Radiometer Theory

We present a derivation of the radiometer equation based on the original references and fundamental statistical concepts. We then perform numerical simulations of white noise to illustrate the radiometer equation in action. Finally, we generate 1/f and 1/f^2 noise, demonstrate that it is non-stationary, and use it to simulate the effect of gain fluctuations on radiometer performance.
An Update on Non-invasive Approaches for Genetic Testing of the Preimplantation Embryo

Preimplantation Genetic Testing (PGT) aims to reduce the chance of an affected pregnancy or improve success in an assisted reproduction cycle. Since the first established pregnancies in 1990, methodological approaches have greatly evolved, combined with significant advances in the embryological laboratory. The application of preimplantation testing has expanded, while the accuracy and reliability of monogenic and chromosomal analysis have improved. The procedure traditionally employs an invasive approach to assess the nucleic acid content of embryos. All biopsy procedures require high technical skill, and costly equipment, and may impact both the accuracy of genetic testing and embryo viability. To overcome these limitations, many researchers have focused on the analysis of cell-free DNA (cfDNA) at the preimplantation stage, sampled either from the blastocoel or embryo culture media, to determine the genetic status of the embryo non-invasively. Studies have assessed the origin of cfDNA and its application in non-invasive testing for monogenic disease and chromosomal aneuploidies. Herein, we discuss the state-of-the-art for modern non-invasive embryonic genetic material assessment in the context of PGT. The results are difficult to integrate due to numerous methodological differences between the studies, while further work is required to assess the suitability of cfDNA analysis for clinical application.
Identifying Cost-Effective Low-Impact Development (LID) under Climate Change: A Multi-Objective Optimization Approach

Low-impact development (LID) is increasingly used to reduce stormwater’s quality and quantity impacts associated with climate change and increased urbanization. However, due to the significant variations in their efficiencies and site-specific requirements, an optimal combination of different LIDs is required to benefit from their full potential. In this article, the multi-objective genetic algorithm (MOGA) was coupled with the stormwater management model (SWMM) to identify both hydrological and cost-effective LIDs combinations within a large urban watershed. MOGA iteratively optimizes the types, sizes, and locations of different LIDs using a combined cost- and runoff-related objective function under both past and future stormwater conditions. The infiltration trench (IT), rain barrel (RB), rain gardens (RG), bioretention (BR), and permeable pavement were used as potential LIDs since they are common in our study area—the city of Renton, WA, USA. The city is currently adapting different LIDs to mitigate the recent increase in stormwater system failures and flooding. The results from our study showed that the optimum combination of LIDs in the city could reduce the peak flow and total runoff volume by up to 62.25% and 80% for past storms and by13% and 29% for future storms, respectively. The findings and methodologies presented in this study are expected to contribute to the ongoing efforts to improve the performance of large-scale implementations of LIDs.
Simulación microclimática de una tormenta urbana utilizando el modelo ENVI-met

El conocimiento de la geografía y de la planificación espacial es un elemento esencial para el desarrollo organizado de las ciudades y la consiguiente mitigación de problemas urbanos, como las islas de calor. En Lisboa (Portugal), los fuertes vientos otoñales que se dirigen hacia el sur o suroeste suelen causar daños, como la caída de árboles, que corresponde al 50% del total de 1.673 caídas registradas entre 1990 y 2008 por los bomberos. Una herramienta disponible para dicha planificación es el software ENVI-met, capaz de realizar simulaciones microclimáticas de la interacción superficie - planta - aire. El objetivo de esta investigación fue analizar el efecto de un viento fuerte en la caída de árboles en un barrio residencial de Lisboa (Portugal), a través del modelado computacional de la localización y caracterización de los diferentes tipos de edificios, vegetación y suelos. Para el procesamiento de datos, se requerían dos archivos: el primero, extensión . in (modelado de área), y el segundo, extensión . cf (archivo de configuración, que contiene variables climáticas). El fenómeno estudiado ocurrió el 24 de noviembre de 2006, con vientos de 13 m/s, según la Estación Meteorológica Gago Coutinho (Estación número 085790), y derribó al menos 66 árboles en la ciudad, según el Departamento de Bomberos. Con la simulación, zonas de aceleración del viento han sido mapeadas, donde el diseño del área demostró tener una gran influencia, ya que los cañones urbanos pueden facilitar las caídas al canalizar altas velocidades de viento. En estos lugares más vulnerables, es importante prestar especial atención al uso y ocupación de la tierra, con árboles con mayor resistencia biomecánica y raíces más profundas, para garantizar su sustento. El modelo ENVI-met se puede utilizar para predecir escenarios futuros de fenómenos naturales, ayudando a la gestión urbana actual.
Assessing the Development Level of Logistics for Sustainable Cities in Urban Agglomeration Based on a Multi-Layer Complex Network

Evaluating the development level of urban logistics can significantly inform policies for the sustainable development of each city in an urban agglomeration. This study analyzed the logistics development of 11 cities in the Guanzhong Plain urban agglomeration (GPUA) of China. Compared to traditional urban logistics evaluation methods considering individual attributes, this study constructed a multi-layer complex logistics network of urban agglomerations (MCLNUA) based on complex network theory, which takes into account the multiple connections between cities. The development levels of logistics in these cities were evaluated from a multi-dimensional perspective of “point–line–surface”, (the “point” represents the node characteristic index of the city, the “line” represents the strength and direction of urban logistics connections between cities, and the “surface” represents the cohesive subgroup of cities). An urban spatial hierarchy and corresponding spatial development plan for urban logistics were also developed. The results show that there are significant differences in logistics levels between different cities. The spatial structure of the overall network connections shows the pattern of being strong in the south and weak in the north, and strong in the east and weak in the west. There are differences in the strength of connections between cohesive subgroups. The research provides a reference for the sustainable development of regional logistics in other urban agglomerations.
Association between Pediatric Adenovirus Infection and Type 1 Diabetes

Background: Viruses are among the inducers of type 1 diabetes (T1D) as they are implicated in the initiation of β-cell destruction. This study aimed to explore the link between adenoviruses’ infection, inflammatory biomarkers, and the development of T1D. Methods: The study population included 80 children with T1D and 40 healthy controls (2–16 years old). The T1D group was further clustered into two groups according to time of T1D diagnosis: a group of children who were diagnosed during the first year of life and a second group who were diagnosed after the first year of life. Adenovirus DNA, anti-adenovirus IgG, cytokines, and lipid profiles were screened in the different groups. The results were statistically assessed using one-way analysis of variance (ANOVA) and LSD t-test. Results: Positive adenovirus PCR was detected in 2.5% and 20% of normal and T1D children, respectively. Moreover, the positive PCR results for adenovirus were found significantly higher in the T1D group, who were diagnosed during the first year of life (33.4%), in comparison to those diagnosed after the first year of life (12%). Anti-adenoviruses IgG was found in 12.5% and 40% of healthy controls and diabetic children, respectively. Seropositive results were found to be higher in newly diagnosed children (46.7%) in comparison to those previously diagnosed with T1D (36%). Body mass index (BMI), IFN-γ, IL-15, adiponectin, lipid profile, and microalbuminuria were significantly increased in T1D adenoviruses-positive children compared to children who were negative for adenoviruses. Conclusions: Adenovirus infection could be among the contributing risk factors and may play a role in the induction of T1D in children.
Trajectories with suppressed tensor-to-scalar ratio in Aligned Natural Inflation

In Aligned Natural Inflation, an alignment between different potential terms produces an inflaton excursion greater than the axion scales in the potential. We show that, starting from a general potential of two axions with two aligned potential terms, the effective theory for the resulting light direction is characterized by four parameters: an effective potential scale, an effective axion constant, and two extra parameters (related to ratios of the axion scales and the potential scales in the 2−field theory). For all choices of these extra parameters, the model can support inflation along valleys (in the 2−field space) that end in minima of the potential. This leads to a phenomenology similar to that of single field Natural Inflation. For a significant range of the extra two parameters, the model possesses also higher altitude inflationary trajectories passing through saddle points of the 2−field potential, and disconnected from any minimum. These plateaus end when the heavier direction becomes unstable, and therefore all of inflation takes place close to the saddle point, where—due to the higher altitude—the potential is flatter (smaller ϵ parameter). As a consequence, a tensor-to-scalar ratio r = O ( 10−4 − 10−2 ) can be easily achieved in the allowed ns region, well within the latest 1 σ CMB contours.
