Human Milk and Brain Development in Infants

Human milk is considered the most advantageous source of nourishment for infants. Even though there is no ideal composition of human milk, it still contains a unique combination of components that contribute to brain development. The aim of this review is to provide an overview on the possible correlation of human milk with the neurodevelopment of infants, with a special emphasis on myelination and epigenetic modifications. Research in human milk is a rapidly expanding field and cutting-edge technologies might contribute to identify specific mechanisms underlying the beneficial effects on human milk on neurodevelopment.
Stress Reversals near Hydraulically Fractured Wells Explained with Linear Superposition Method (LSM)

Prior studies have noted that the principal stress orientations near the hydraulic fractures of well systems used for energy extraction may wander over time. Typically, the minimum and maximum principal stresses—in the horizontal map view—swap their respective initial directions, due to (1) fracture treatment interventions, and (2) pressure depletion resulting from production. The present analysis shows with stress trajectory visualizations, using a recently developed linear superposition method (LSM), that at least two generations of stress reversals around hydraulic fractures occur. The first generation occurs during the fracture treatment; the second occurs immediately after the onset of so-called flow-back. During each of these stress swaps in the vicinity of the hydraulic fractures, reservoir directions that were previously in compression subsequently exhibit extension, and directions previously stretching subsequently exhibit shortening. The pressure change in the hydraulic fractures—from over-pressured to under-pressured (only held open by proppant packs)—caused the neutral points that separate domains with different stress states to migrate from locations transverse to the fracture to locations beyond the fracture tips. Understanding such detailed geo-mechanical dynamics, related to the pressure evolution in energy reservoirs, is extremely important for improving both the fracture treatment and the well operation, as future hydrocarbon and geothermal energy extraction projects emerge.
Linking Public Finances’ Performance to Renewable-Energy Consumption in Emerging Economies of the European Union

Implementing public policies linked to sustainable development is a global challenge for most countries that focused their efforts on identifying and improving the factors that led to environment degradation. The current paper analyzes the influence of primary indicators of public finances (public debt and budget deficit) on renewable-energy consumption (REN), for the emerging economies within the European Union. The main objective of this research is to understand the implications of fiscal measures on the sustainable development of a country and thus provide directions for stimulating renewable-energy consumption. The research starts with cross-sectional dependence analysis by using the Breusch–Pagan Lagrange multiplier (LM) test that is followed by cointegration relationships among variables by applying two appropriate panel-cointegration tests (Pedroni and Johansen). The research methodology is based on the fully modified ordinary-least-squares (FMOLS) method in order to test the long-run relationships, and on the pairwise Granger causality test in order to identify the direction of causality among variables. Results show unilateral influences from public debt and budget deficit on the analyzed variables, especially on renewable-energy consumption, and a bidirectional causality relationship between budget deficit and trade openness.
SALDR: Joint Self-Attention Learning and Dense Refine for Massive MIMO CSI Feedback With Multiple Compression Ratio

The advantages of massive multiple-input multiple-output (MIMO) techniques depend heavily on the accuracy of channel state information (CSI). In frequency division duplexing (FDD) massive MIMO systems, the user equipment (UE) needs to feed downlink CSI back to the base station (BS) through the feedback link. The excessive feedback overheads and low reconstruction accuracy are the main obstacles for actual deployment of FDD massive MIMO systems. In recent years, deep learning (DL) has been widely used to address the above problems. In this letter, we propose a neural network by utilizing the self-attention learning and dense refine (SALDR), which improves the accuracy of CSI feedback. Furthermore, a unified decoder named SALDR-U is designed to realize different compression ratios for CSI feedback without changing any parameter. Simulation results show that the proposed SALDR and SALDR-U outperform the state-of-the-art network in terms of accuracy and overhead of CSI feedback. The source code for all the experiments is available at GitHub.The code of this letter can be downloaded from GitHub link: https://github.com/XS96/SALDR.
Effects of Different Preservatives on Cut Flower of Luculia pinceana: A Novel Fragrant Ornamental Species

Luculia pinceana is a potential cut flower because of its long-term blooming inflorescences and charming fragrance. However, its narrow distribution area and unexplored wild status severely restrict its applications, thus leading to the scientific research of cut L. pinceana flowers. To our knowledge, there is no available published information about the postharvest fresh-keeping of L. pinceana. During this study, the cut flowers of L. pinceana were tested using nine preservatives with different concentrations of sucrose and 8-hydroxyquinoline (8-HQ) to evaluate the fresh-keeping effects. Through the investigation and analysis of vase life, bud opening and abortion rate, water balance, malonaldehyde (MDA) content, and peroxidase (POD) activity, we selected and identified the best vase solution for cut L. pinceana flowers. The results suggested that the preservative of 1% sucrose and 100 mg/L 8-HQ could significantly prolong the vase life of cut L. pinceana flower up to 9 days compared with water control. This solution positively affects flower bud blooming, delays flower senescence, improves the water balance, inhibits the MDA accumulation, and increases POD activity. Therefore, this preservative is suitable for the fresh-keeping of cut L. pinceana flowers. Our study is the first to report the effects of preservatives on cut L. pinceana flower. The results showed that the low-sugar-containing (1% sugar) preservatives can effectively improve the ornamental quality of fresh flowers and demonstrated that the postharvest fresh-keeping of L. pinceana requires low sugar and is insensitive to microorganisms.
Low-Wage Women’s Experiences of Workplace Incivilities

Workplace incivility, also called bullying, mobbing, and harassment, is pervasive and takes a high toll on employees. This study draws on 18 in-depth interviews with women in the precarious, low-wage, service sector in jobs such as customer service representative, retail sales, food service, pharmacy technician, and bank teller. Women service workers are a particularly vulnerable group, and yet most research on workplace problems of this type focus on professional women’s experience. We find that in this sample, most incivilities came from supervisors, followed by customers and then coworkers. Among supervisors, women were the most common perpetrators, while customer and coworker perpetrators were largely men. The type of incivility varied depending on role: Disparagement was common on the part of supervisors and customers, while coworkers were far more likely to engage in sexual harassment, which was virtually nonexistent among supervisors. Consequences for targets of these incivilities included anxiety, which most had experienced, and income loss. We offer suggestions for future research and policy.
Marginal Lives and the Microsociology of Overhearing in the Jamuna Chars

ABSTRACT In the past decade, Bangladesh has made a shift to becoming an authoritarian state. What happens to everyday speech within the context of state repression and censorship? I take up this question by exploring the nature and fate of ‘overhearing’ as a mode of speaking, most often prefaced by, ‘I heard that,’ or ‘this is heard speech,’ among the underprivileged denizens of the chars in the Jamuna River during the 2014 National Elections. The interest in drawing attention to overhearing, as opposed to eavesdropping or rumouring to which overhearing bears a resemblance, is to highlight a mode of speaking that stands to fall victim to the disciplining of speech currently underway in Bangladesh. In disciplining overhearing we stand to loose a practice, which, despite being intermittent and ephemeral, espouses an aesthetic sensibility and extends socio-religious judgments into the realm of nature, increasing the scope for political critique.
Intraoperative frozen section performance for thyroid cancer diagnosis

ABSTRACT Objective: A primary medical relevance of thyroid nodules consists of excluding thyroid cancer, present in approximately 5% of all thyroid nodules. Fine-needle aspiration biopsy (FNAB) has a paramount role in distinguishing benign from malignant thyroid nodules due to its availability and diagnostic performance. Nevertheless, intraoperative frozen section (iFS) is still advocated as a valuable tool for surgery planning, especially for indeterminate nodules. Subjects and methods: To compare the FNAB and iFS performances in thyroid cancer diagnosis among nodules in Bethesda Categories (BC) I to VI. The performance of FNAB and iFS tests were calculated using final histopathology results as the gold standard. Results: In total, 316 patients were included in the analysis. Both FNAB and iFS data were available for 272 patients (86.1%). The overall malignancy rate was 30.4%% (n = 96). The FNAB sensitivity, specificity, and accuracy for benign (BC II) and malignant (BC V and VI) were 89.5%, 97.1%, and 94.1%, respectively. For all nodules evaluated, the iFS sensitivity, specificity, and accuracy were 80.9%, 100%, and 94.9%, respectively. For indeterminate nodules and follicular lesions (BC III and IV), the iFS sensitivity, specificity, and accuracy were 25%, 100%, and 88.7%, respectively. For BC I nodules, iFS had 95.2% of accuracy. Conclusion: Our results do not support routine iFS for indeterminate nodules or follicular neoplasms (BC III and IV) due to its low sensitivity. In these categories, iFS is not sufficiently accurate to guide the intraoperative management of thyroidectomies. iFS for BC I nodules could be an option and should be specifically investigated
“It’s Not Particularly P.C., You Know . . .”: Women Coaches’ Performing Gender in Strength and Conditioning

Strength and conditioning (S&C) has become a chief part of athletes’ physiological preparation. Despite S&C’s growing presence across sports, women coaches have been generally marginalized and underrepresented. This study explores female S&C coaches’ experiences and coping mechanisms in a male-dominated industry. Semi-structured interviews with 15 female S&C coaches were conducted. The main themes identified from interview data are organizational politics, impression management, and humor. The findings suggest that women S&C coaches are often in subservient positions and have to adopt some traditional, male-generated subcultural practices to fit in. They carefully manage their coaching front stage to generate an impression that is expected and accepted in the given milieu. In their efforts to fit in, women often find themselves in a multiplicity of power matrices that involve a continuous negotiation of gender identity, internal politics, and sexist banter.
Winning by Learning? Effect of Knowledge Sharing in Crowdsourcing Contests

Crowdsourcing is a new way for online crowds to get involved in a company’s research and development process. Businesses can host public contests on online platforms (such as Kaggle, Topcoder, and Tongal) to seek new product ideas and technological solutions. In the contest communities, members usually have a “coopetitive” relationship: they compete against each other for the contest prize, while at the same time also cooperate with each other by sharing information and knowledge. This work investigates the effect of knowledge sharing in such crowdsourcing contests. Surprisingly, we find that the knowledge sharing process may not always help improve crowdsourcing contestants’ performance. The effectiveness of knowledge sharing is influenced by the volume, quality, and generativity of shared knowledge. Shared knowledge is only beneficial when it is of high quality or when it has high potential of being further developed collectively by the community. Meanwhile, the development process has to be diverging; narrowing the development process in one direction can restrict the community creativity and negatively influence crowdsourcing performance. Our work informs the crowdsourcing practitioners to be more cautious when they enable collaboration such as knowledge sharing for the contest community.
Climate Change Perceptions by Smallholder Coffee Farmers in the Northern and Southern Highlands of Tanzania

Smallholder farmers are among the most vulnerable groups to climate change. Efforts to enhance farmers’ adaptation to climate change are hindered by lack of information on how they are experiencing and responding to climate change. Therefore, this paper examines smallholder farmers’ perceptions of climate change, factors influencing their perceptions, and the impacts and adaptation strategies adopted over the past three to four decades. A list of farmers was obtained from the Agricultural Marketing Cooperative Society (AMCOS) and filtered on the basis of age and farming experience. In order to explore factors influencing household perceptions of climate change, a structured questionnaire was administered to the randomly selected household heads. Data on rainfall and temperature were acquired from Lyamungo and Burka Coffee estate (Northern Highlands zone) and Mbimba and Mbinga (Southern Highlands zone) offices of the Tanzania Meteorological Agency (TMA) with the exception of data from Burka Coffee estate, which were acquired from a private operator. Descriptive statistics and logistic regression models were used to analyze the data. Farmers’ perceptions were consistent with meteorological data both pointing to significant decline in rainfall and increase in temperature since 1979. Factors such as level of education, farming experience, and access to climate information influenced farmers’ perception on climate change aspects. Based on these results, it is recommended to enhance timely and accurate weather information delivery along with developing institutions responsible for education and extension services provision. The focus of education or training should be on attenuating the impacts of climate change through relevant adaptation measures in each coffee-growing region.
Dynamic Functional Principal Components for Testing Causality

In this paper, we investigate the causality in the sense of Granger for functional time series. The concept of causality for functional time series is defined, and a statistical procedure of testing the hypothesis of non-causality is proposed. The procedure is based on projections on dynamic functional principal components and the use of a multivariate Granger test. A comparative study with existing procedures shows the good results of our test. An illustration on a real dataset is provided to attest the performance of the proposed procedure.
A Biomechanical and Microstructural Analysis of Bovine and Porcine Pericardium for Use in Bioprosthetic Heart Valves

ABSTRACT Background Animal-derived pericardium is a key material that enables the successful clinical use of bioprosthetic heart valves. Recently, transcatheter heart valves have placed more emphasis on the enhancement of this tissue, especially in terms of producing a uniform, thin, durable tissue. In this study, we provide a new method to achieve thinner tissue and new insights into how to achieve a more consistent tissue, which potentially may lead to more durable heart valves. Methods We compared four groups of tissue: porcine pericardium, bovine pericardium; delaminated serous bovine pericardium, and delaminated fibrous bovine pericardium. The properties we compared were: surface characteristics, collagen fiber alignment, collagen fiber alignment patterns, and tensile mechanical properties. Results We produced thinner tissue that had statistically significantly reduced surface roughness and was not mechanically inferior. Furthermore, we demonstrated that porcine tissue has more distinct collagen fiber directions between the fibrous and serous sides. The maximum observed difference in average fiber angles between the different sides of porcine tissue was 52.3° (±25.9°) and 33.4° (±27.1°) for bovine tissue, this was statistically significantly different. Conclusion The results indicate that screening heart valve leaflet pericardial tissue to identify optimally aligned collagen fiber directions is not viable. We propose an alternative approach: utilizing tissue with eccentricity values below a threshold value of 0.65 and discarding tissue with eccentricity values above 0.65. If screening procedures are not available, our results suggest that non-screened porcine pericardial tissue would produce more consistent mechanical properties, as areas with aligned collagen fibers are not consistently present in porcine tissue.
SOCIAL SATIRE ON HIGHER EDUCATION: A COMPARATIVE STRUCTURAL SEMIOTIC STUDY OF THE MOVIES ALANGKAH LUCUNYA (NEGERI INI) AND PARASITE

It is commonly believed that obtaining a higher education is one way to elevate people's social class. Two movies, the Indonesian film Alangkah Lucunya (Negeri Ini) ALNI (2010) and the Korean Parasite (PR) (2019), challenge this common belief. The two movies criticize higher education by conveying the message in satire. To unveil the meaning of the two movies' social satires, this study used Roland Barthes's structural semiotic analysis on five primary codes to explore the codes that regulate the structure of the narrative of the text (film) to find similarities and differences of their focus of criticism regarding higher education. The use of satiric form to contrast and juxtapose the rich and the poor, and the educated and uneducated shows that both Alangkah Lucunya (Negeri Ini) and Parasite uncover the influence of neoliberalism in the formal educational system that gives an impact to both lower and higher class, either in developed countries or developing countries. The satire content is intended to attract attention and to inspire people to move to change the situation.
Short-term Adaptation Strategy Improved Xylitol Production by Candida guilliermondii on Sugarcane Bagasse Hemicellulosic Hydrolysate

In this work, we proposed a short-term adaptation strategy to improve xylitol production on sugarcane bagasse hemicellulosic hydrolysate through the maximization of Candida guilliermondii FTI 20037 tolerance to inhibitors. Hemicellulosic hydrolysate obtained by diluted acid hydrolysis (1.0% (wv −1 ) H 2 SO 4 , 1:10 solid/liquid ratio, 121 °C, 10 min) was concentrated up to fivefold to obtain hydrolysates with different concentration factors. Yeast was cultivated in each hydrolysate for 24-h and consecutively transferred to the subsequent more concentrated hydrolysate to obtain different adaptation degrees. Adapted cells were used as inoculum in fermentations with the same hydrolysate in which they were adapted. The performance of adapted and non-adapted yeast was compared to validate the adaptation strategy employed. The beneficial effects of adaptation were more pronounced in the hydrolysates with higher inhibitor concentration (twofold concentrated and non-treated, H2N; and fivefold concentrated and treated, H5). It improved xylose assimilation and xylitol production as well as xylitol yield and xylitol volumetric productivity in both hydrolysates. A 62.5% increase in productivity (0.24 to 0.39 gL −1 h −1 ) and a 15.7% increase in yield (0.51 to 0.59 gg −1 ) were observed for H5 hydrolysate, while for H2N hydrolysate these increases were 54.5 and 29.6%, respectively. Yeast adaptation also improved arabinose consumption and reduced glycerol production. The reduction in glycerol production indicates a greater tolerance of adapted cells to the inhibitors present in hydrolysates. Short-term adaptation proved to be an efficient strategy to improve yeast tolerance as well as its fermentative performance on sugarcane bagasse hemicellulosic hydrolysate.
Transition from transesophageal echocardiography to cardiac computed tomography for the evaluation of left atrial appendage thrombus prior to atrial fibrillation ablation and incidence of cerebrovascular events during the COVID‐19 pandemic

Transesophageal echocardiography (TEE) is variably performed before atrial fibrillation (AF) ablation to evaluate left atrial appendage (LAA) thrombus. We describe our experience with transitioning to the pre‐ablation cardiac computed tomography (CT) approach for the assessment of LAA thrombus during the COVID‐19 pandemic.
The Healing Effect of Lactobacillus plantarum Isolated from Iranian Traditional Cheese on Acetic Acid Induced Gastric Ulcer in Rats

Background : Probiotics are defined as “living organisms which upon ingestion in certain numbers, exert health benefits beyond inherent basic nutrition". One of the most significant groups of probiotic organisms are the lactic acid bacteria, commonly used in fermented dairy products. The actions of lactic acid bacteria are species and strain specific and depend on sufficient numbers of bacteria being available in the intestine. The difficulty in identifying and classifying strains has complicated researches, since benefits may only pertain to particular strains. The aim of the present study is to investigate the effect of a probiotic strain Lactobacillus plantarum isolated from Iranian traditional cheese on gastric ulcer healing. Methods : In this experimental study 22 strains of lactic acid bacteria isolated from Iranian traditional cheese were investigated for Exopolysaccharide (EPS) production by phenol-sulfuric acid method which had been approved earlier for the ability of survival and growth in digestive system. To determine the effect of this probiotic strain, male wistar rats were divided into 3 groups; experimental, control and negative control. Rats were deprived of food but not water for 24 hours and gastric ulcers were induced by luminal application of 0.12 ml acetic acid solution (60% v/v). One day after ulcer induction, the experimental groups received sterilized milk with Lactobacillus plantarum at concentration of 1×10 10 cfu/day, the control groups received sterilized milk and the negative control groups received normal saline through oral gavage for few consecutive days. Rats were sacrificed on days 5 and 14 after ulcer induction and the ulcer sizes (mm 2 ) were summed. After histological study the effect of this probiotic on gastric ulcer healing was determined in each stomach. Data were analyzed with One way ANOVA test and all results were reported as Mean ± SEM. Results: Lactobacillus plantarum significantly decreased gastric ulcer area compared to control and negative control groups and increased ulcer healing. Histological study on day 5 after ulcer induction showed significant reduction in number of neutrophils and significant increases in macrophages and fibroblasts (p<0.001). Also significant reduction in the number of neutrophils, macrophages and fibroblasts was observed on day 14 after ulcer induction (p<0.001). Conclusion: Lactobacillus plantarum showed significant effects on gastric ulcer healing induced by acetic acid in rats.
