Corporate governance mechanism and profitability: A special assessment on the board of commissioners and audit committee

This study aims to examine the effect of corporate governance mechanisms on the percentage of profits in manufacturing companies. The population in this study is manufacturing companies in the industrial & chemical sector, which are listed on the Indonesia Stock Exchange (IDX) during the 2017-2019 period. The samples were selected using purposive sampling method and resulted in 34 manufacturing companies in the industrial and chemical sectors. Data were taken from the Indonesia Stock Exchange for the 2017-2019 period. The independent variable in this study is corporate governance with a focus on the board of commissioners and the audit committee, while the dependent variable is the effect of profit percentage on manufacturing companies. This study used simple linear regression analysis. From the regression analysis in this study, the two corporate governance proxies which include the board of commissioners and the audit committee have a significant positive effect on company profits. These results provide evidence that the existence of a board of commissioners and an audit committee in manufacturing companies in Indonesia has been effectively associated with the company’s profit percentage gain. © 2022 by the authors.

Center of Milky Way Galaxy

In 2013, World-Universe Model (WUM) made one of the most important predictions: “Macroobjects of the World have cores made up of the discussed DM (Dark Matter) particles. Other particles, including DM and baryonic matter, form shells surrounding the cores” [1]. Prof. R. Genzel and A. Ghez confirmed this prediction: “The Discovery of a Supermassive Compact Object at the Centre of Our Galaxy” (Nobel Prize in Physics 2020). On May 12, 2022, astronomers, using the Event Horizon Telescope, released the first image of the accretion disk around the Sagittarius A*(Sgr A*) produced using a world-wide network of radio observatories made in April 2017. These observations were obtained by a global array of millimeter wavelength telescopes and analyzed by an international research team that now numbers over 300 people, which claimed that Sgr A* is a Supermassive Black Hole (SBH). In the present paper we analyze these results in frames of WUM. Based on the totality of all accumulated experimental results for the Center of the Milky Way Galaxy we conclude that Sgr A* is the DM Core of our Galaxy.
A Novel Bit Rate Adaptation using Buffer Size Optimization for Video Streaming

Video streaming application such as YouTube is one of the most popular mobile applications. To adjust the quality of video for available network bandwidth, a streaming server provides multiple representations of video of which bit rate has different bandwidth requirements. A streaming client utilizes an adaptive bit rate scheme to select a proper video representation that the network can support. The download behavior of video streaming client player is governed by several parameters such as maximum buffer size. Especially, the size of the maximum playback buffer in the client player can greatly affect the user experience. To tackle this problem, in this paper, we propose the maximum buffer size optimization according to available network bandwidth and buffer status. Our simulation study shows that our proposed buffer size optimization scheme successfully mitigates playback stalls while preserving the similar quality of streaming video compared to existing ABR schemes.
Somatosensory Profiles Differentiate Pain and Psychophysiological Symptoms Among Young Adults With Irritable Bowel Syndrome

Objective: The aim of this study was to investigate if somatosensory profiles can differentiate pain and psychophysiological symptoms among young adults with irritable bowel syndrome (IBS). Methods: We performed a cluster analysis of data collected from a randomized clinical trial of 80 IBS patients and 21 age-matched healthy controls (HCs) to stratify pain and symptoms among young adults with IBS by their peripheral sensory profiles. Data of quantitative sensory testing and IBS-related pain and symptoms were collected at baseline and 6-week and 12-week follow-ups. Results: Using the K-means method, IBS patients were classified into 2 clusters, the “IBS normal threshold” (IBS-NT) and the “IBS increased threshold” (IBS-IT). The IBS-NT cluster had a similar pain threshold as the HCs, and the IBS-IT cluster had an increased threshold of somatic pain perception (lower cold pain threshold, higher heat pain threshold, and higher pressure pain threshold, all P<0.001) than HCs. Compared with the IBS-NT cluster, the IBS-IT cluster reported higher levels of IBS-related pain intensity, anxiety, fatigue, and sleep disturbance over the 3 visits (all P<0.05). Discussion: Young adults with IBS fell into 2 clusters, one with a similar sensory threshold as the HCs and another with an increased pain threshold, who reported higher pain intensity and more severe symptoms. Somatic sensory profiles should be integrated into further personalized self-management intervention among patients with IBS.
LECTURE NOTES ON HIGHER CATEGORIES

These are lecture notes for a course on higher categories in Spring 2020 at École Polytechnique Fédérale de Lausanne. The goal is to focus on certain aspects that are usually undercovered in the ∞-category world. In particular, the fact that an ∞-category is a concrete object: a simplicial set, a simplicial space, a simplicial category, . and there are various ways to move between these notion.
Quantifying the potential market for new contraceptive technologies : global projections of 2040 contraceptive needs and preferences

There has been a growing recognition in the UK that the statutory storage limit for frozen eggs, which currently stands at 10 years, requires a review. The UK regulator, the Human Fertilization and Embryology Authority (HFEA), has recognized the problem and the Equality and Human Rights Commission is also sympathetic with the demand to change the current legislation. There is also strong desire on the part of assisted reproductive technology (ART) professionals and patients to change the current guidelines. For many women, the available alternatives of transporting their eggs to an overseas destination or having them fertilized with donor sperm and then stored as embryos is objectionable.
Retail Investors ’ Contrarian Behavior Around Earnings , Attention , and the Momentum Effect *

Using a large panel of U.S. accounts trades and positions, we show that retail investors trade as contrarians after large earnings surprises, especially for loser stocks, and such contrarian trading contributes to post earnings announcement drift (PEAD) and momentum. Indeed, when we double-sort by momentum portfolios and retail trading flows, PEAD and momentum are only present in the top two quintiles of retail trading intensity. Finer sorts confirm the results, as do sorts by firm size and institutional ownership level. We show that the investors in our sample are representative of the universe of U.S. retail traders, and that the magnitude of the phenomena we describe indicate a quantitively substantial role of retail investors in generating momentum. The results on the timing of the flows and the magnitude of the return differences across momentum portfolios by retail trading intensity and size and sign of the earnings surprise, are confirmed at a longer two-year horizon. Alternative hypotheses, such as the disposition effect and stale limit orders, do not explain the phenomenon. We find that younger investors and day traders are more likely to be contrarians, while gender and number of trades are not correlated with our contrarian score, once other characteristics are controlled for. The pattern of web-clicks and the time spent analyzing each stock on the brokerage platform suggest an important role of attention in contrarian trading. * Farallon Capital Management ** Federal Reserve Bank of Chicago + Harvard Business School, Finance Unit * We thank Terry Odean, seminar participants at Harvard Business School, the Swedish House of Finance, HKUST, the City University of Hong Kong, UBC Winter Finance Conference, the CEPR Household Finance Seminar Series, Georgetown Fintech Seminar Series, and the Boulder Summer Conference on Consumer Decision Making for helpful comments and suggestions.

Marrow Niche Mice: A Novel Function of Foxn1 in the Bone Enhancing T Lineage Production in Aged

Foxn1 is essential for thymic organogenesis and T lymphopoiesis. Whereas reduced Foxn1 expression results in a decline in T lymphopoiesis, overexpression of Foxn1 in the thymus of a transgenic mouse model (Foxn1Tg) attenuates the age-associated decline in T lymphopoiesis. T lymphopoiesis begins with early T cell progenitors (ETP), derived from multipotent progenitors (MPP) in the bone marrow (BM). A decline in MPP and ETP numbers with age is thought to contribute to reduced T lympho-poiesis. Previously, we showed that reduced ETP number with age is attenuated in Foxn1 transgenic (Tg); whether the effect is initiated in the BM with MPP is not known. In this study, we report that Foxn1 is expressed in wild-type BM and overexpressed in Foxn1Tg. With age, the number of MPP in Foxn1Tg was not reduced, and Foxn1Tg also have a larger pool of hematopoietic stem cells. Furthermore, the Foxn1Tg BM is more efficient in generating MPP. In contrast to MPP, common lymphoid progenitors and B lineage cell numbers were significantly lower in both young and aged Foxn1Tg compared with wild type. We identified a novel population of lineage neg/low , CD45 pos EpCAM pos , SCA1 pos , CD117 neg , CD138 neg , MHCII neg cells as Foxn1-expressing BM cells that also express Delta-like 4. Thus, Foxn1 affects both T lymphopoiesis and hematopoiesis, and the Foxn1 BM niche may function in skewing MPP development toward T lineage progenitors. T he gene encoding the forkhead box n1 (Foxn1) transcription factor is the essential single gene responsible for thymic organogenesis and consequently T lymphopoiesis (1). Foxn1 was discovered in nude mice carrying a spontaneous mutation that results in the athymic and hairless phenotypes (2). Previously, we demonstrated that the decline of Foxn1 expression in the thymic stroma with age correlates with the decline in thy-mocyte number, suggesting a role for Foxn1 in thymic involution (3). Others found that deletion of Foxn1 in the postnatal thymus results in premature thymic involution (4, 5). Naive T cells develop from early T cell progenitors (ETP) in the thymus (6, 7). The decline in the frequency and number of ETP with age contributes to decreased T lymphopoiesis (8). ETP are nonself-renewing, and therefore the thymus relies on the bone marrow (BM) for a continuous supply of progenitors to maintain T lymphopoiesis (9, 10). The multipotent progenitor (MPP) population in the BM is thought to contain the precursor to thymic ETP …

The single biggest problem in communication is the illusion that it has taken place . –

Using a large-scale survey of U.S. households during the COVID-19 pandemic, we study how new information about fiscal and monetary policy responses to the crisis affects households’ expectations. We provide random subsets of participants in the Nielsen Homescan panel with different combinations of information about the severity of the pandemic, recent actions by the Federal Reserve, stimulus measures, as well as recommendations from health officials. This experiment allows us to assess to what extent these policy announcements alter the beliefs and spending plans of households. In short, they do not, contrary to the powerful effects they have in standard macroeconomic models.
An Overview of Zinc and its Intralesional Role in Treatment of Multiple Recalcitrant Warts: Review Article

Background: Human papilloma virus (HPV) causes viral warts, which affect around 10% of the population. HPV types 1, 2, and 57 are frequently implicated as etiological factors in the majority of cases. It's more difficult to diagnose and cure HPV 4 and 7 because of their rarity. It is possible to combine several treatments for viral warts because treatment might be time-consuming in some circumstances, even when various options are accessible. In spite of reports of successful systemic acitretin therapy for viral warts resistant to previous treatments, oral acitretin therapy has only been used in a limited number of cases. Objective: Assessment of role of intralesional zinc sulphate 2% in the treatment of multiple recalcitrant warts. Methods: Warts, Zinc sulphate, Recalcitrant warts, and the Human Papillomavirus were all looked for in PubMed, Google scholar, and Science direct. References from relevant literature were also evaluated by the authors, but only the most recent or complete study from January 2000 to January 2022 was included. Due to the lack of sources for translation, documents in languages other than English have been ruled out. Papers that did not fall under the purview of major scientific investigations, such as unpublished manuscripts, oral presentations, conference abstracts, and dissertations, were omitted. Conclusion: Warts can also be cleared with intralesional 2 percent zinc sulphate. Children may benefit from using topical or oral zinc as an alternative to harsh manual treatments for warts.
Precise and robust sideslip angle estimation based on INS/GNSS integration using invariant extended Kalman filter

Sideslip angle estimation is vital to the safety and active control of autonomous vehicles. In this paper, an innovative vehicle kinematic-based sideslip angle estimation method is proposed. The method is built on multi-sensor fusion, which fuses the information of inertial measurement unit, global navigation satellite system (GNSS), and onboard sensors to continuously estimate the attitude and velocity of the vehicle and thus obtain the sideslip angle. The invariant extended Kalman filter framework is adopted and the left-invariant form is derived to implement the GNSS measurement update. In order to solve the unobservability problem when only a single GNSS receiver is equipped, the vehicle motion constraint is introduced into the filter to improve the accuracy of heading angle estimation. The method is validated by field test and the results show that the method is robust in terms of converge efficiency. Furthermore, the sideslip angle estimation accuracy is satisfactory with the average absolute error less than 0.25°, which meets the active safety control requirements for autonomous driving.
Uterine Packing with Gauze Versus Bakri Balloon for Arresting Atonic Postpartum Hemorrhage after Cesarean Delivery

Background: There is no adequately sufficient evidence to determine the effectiveness and safety of mechanical and surgical interventions for treating primary postpartum hemorrhage (PPH). Objective: To assess the safety, efficacy and acceptability of uterine packing with gauze compared to Bakri balloon tamponade for treatment of atonic PPH after cesarean section. Patients and Methods: A prospective observational study. A total of 176 patients with atonic PPH after cesarean section were treated either with uterine packing with gauze (n=84) or Bakri balloon tamponade (n=92). The success rate together with early and late complications were recorded and statistically analyzed. Results: 90.4 percent of individuals with uterine packing were able to cease their active bleeding compared to 75 percent of those with the Bakri balloons (p<0.05). The uterine packing group's surgery took longer time, and the Bakri Balloon group's requirement for further vascular ligation was much higher, indicating a significant difference in procedure duration and need for further intervention (p<0.05). There were no significant differences in other operational and postoperative statistics between the two groups of patients. Uterine packing patients were more likely to be accepted by the patients (p<0.05), more satisfied with the surgery (p<0.001), and more likely to recommend it to others (p<0.001). Conclusion: Although uterine packing with gauze may require longer time to insert with similar safety to Bakri balloon, yet it is more effective and more acceptable, less costly and readily available.
Dynamic mechanical behaviour of graphene, hexagonal boron nitride reinforced carbon-kevlar, hybrid fabric-based epoxy nanocomposites

An emphasis on the development of lightweight structures in multitudes of engineering applications has broadened the scope for the continual development of fiber-reinforced composites due to their lightweight and superior strength. The current work is aimed to investigate the influence of fillers graphene and hexagonal boron nitride (h-BN) on carbon, Kevlar, and hybrid fabric when they form fiber-reinforced composites. In particular, the properties such as storage modulus, loss modulus, damping factor, and glass transition temperature were determined for various composites to understand the influence of fillers, fabric combinations, and their interaction in synergy. The unique contribution of this work also lies in the inter-correlation of Full width-half Maximum (FWHM) of loss modulus (E”) plots to understand the phenomena of abrasive wear. An inhomogeneity factor based on the Cole-Cole plots termed as circularity index was also calculated by using Full Maximum (F.M.) and the FWHM. Carbon, Kevlar, and hybrid fabric mat reinforced epoxy composites, with 0.1, 0.3 & 0.5 wt% loadings of graphene and h-BN were prepared using the hand layup technique. The Dynamic mechanical analysis (DMA) was performed under temperature sweep (30–200°C). The results were analysed to understand the choice of h-BN with Kevlar fabric for applications needing high damping while graphene with carbon fabric for applications needing high tenacity. A hybrid fabric mat offers a balance of damping and tenacity. It was observed that the GC2 composite showed a 49% increment in storage modulus (E’), and GK2 composites showed a 38% increment in loss modulus (E”) compared to GC0 and GK0 composites.
Approximate Aggregate Utility Maximization Using Greedy Maximal Scheduling

In this paper, we study the problem of aggregate utility maximization in multihop wireless networks. Following standard approaches, we consider the dual of a convex optimization problem that can be decomposed into two sub-problems. One of the sub-problem is a scheduling problem that requires enumeration of all maximal independent sets in the network—a well-known NP-hard problem. To overcome this computational complexity, we resort to polynomial-time sub-optimal Greedy Maximal Scheduling (GMS). The majority of this paper is dedicated towards quantifying the sub-optimality that arises in the aggregate utility maximization problem due to GMS. We also provide some insights into factors affecting aggregate utility maximization by providing bounds on the maximum achievable aggregate utility.
Knowledge and Self-Care Management Practice Among Asthmatic Children (6-12 Years): An Educational Intervention Study

Background: Asthma is a highly prevalent chronic respiratory disease which has been increasing worldwide. Education to support self-management is an integral part of asthma care that improves disease control, reduces exacerbations and admissions, and improves quality of life of asthmatic children and their caregivers. Objective: The aim of the current work was to assess factors affecting knowledge and self-care management practice of asthmatics and their care givers and to evaluate the effect of implementing an asthma educational intervention. Patients and Method: An interventional study (pre and post comparison study design) was conducted that compared the change in knowledge and self-care practices among participants before and after implementing a health educational program. Results: Asthma educational intervention significantly increased asthma symptoms control and pediatric asthma quality of life among studied asthmatic children, asthma knowledge and pediatric asthma caregivers quality of life among caregivers of the studied asthmatic children after the application of the educational program (P<0.001). Conclusions: It is postulated that children with asthma who receive an interactive, comprehensive educational program would improve their quality of life, asthma management and asthma control compared with children receiving usual care.
Association between Perceived Social Support, Attitude and Depression among Menopausal Women

Aging is an important fact to consider from the woman’s health perspective. One of the most significant stages of aging is menopause, in which involves physical, psychological, and social changes in life. Aim of the study: explore the association between perceived social support, depression and attitudes among menopausal women. Setting: the study was conducted in gynecologic outpatient clinic affiliated to National Medical Institute in Damanhour City, ElBeheira Governorate. Subjects: A convenience sample of 250 menopausal women was recruited in the study. Tools: four tools were used to collect the data: Basic Data, Structured Interview Schedule, Multidimensional Scale of Perceived Social Support, The Beck Depression Inventory, and Attitudes towards Menopause Scale (ATMS). Findings : the study revealed that, statistical significant positive relationship was found between perceived social support and attitude toward menopause (P=0.005). While, statistical significant negative relationship was found between perceived social support and depression (P= 0.002). Conclusion: social support plays a significant role in alleviating feeling of depression and improving women's attitude toward menopausal changes. Recommendations: the nurses should be assess attitude and levels of depression among menopausal women periodically. Educational programs should be carried out for women's families to provide them with information regarding the importance of social support for women during menopause.
