High demand on as consume fish nor as decorative fish, causes an increasing production. But, an obstacle occurs on production, due to reproductive characteristic of Common Carp fish. Different time on sperm and eggs production from male and female fish cause difficulties in breeding. Hence, it needed sperm preservation so the breeding could be done in whole year. Natural extenders are the solution to preserve fish sperm without side effect. The purpose of this study was to determine the effect of different types of extenders and different doses on the percentage of sperm motility and viability of carp (Cyprinus carpio) after storage This research was conducted at the Faculty of Fisheries and Marine Sciences, Universitas Brawijaya and the Freshwater Cultivation Installation (IBAT Punten), Batu, East Java. The method in this study was Complete Random Design (CRD) with 6 treatments, K (100ml lactate ringer); A (1ml cider + 99ml lactate ringer); B (1ml coconut + 99ml lactate ringer); C (1ml date juice + 99ml lactate ringer); D (1ml honey + 99ml lactate ringer); E (1ml sugar cane + 99ml lactate ringer). The results showed that the highest motility was obtained in the treatment of using date extract extender with a motility percentage rate of 77.66%; highest viability was obtained in the honey extract with 80.71%; and the highest fertility rate was obtained in the honey extract treatment with 72.67 %.

Bali cattle have advantages in terms of adaptation and fertilization rates, but tend to have slow growth rate because the rearing system is still grazing so that livestock growth becomes uncontrollable. This study aims to determine the peak of mating and calving estimation of Bali cattle (Bos sondaicus) that did not experience reproductive disorders, aged 4-7 years, belonging to smallholder farmers. The cattle were reared in semi-arid area of Netemnanu village, South Amfoang district, Kupang regency, Nusa Tenggara Timur. The method used was interviews with farmers, diagnosis of pregnancy through rectal palpation and ultrasonography. The results showed that the pregnancy rate was 86.20% (50/58). Based on pregnancy data, it was known that the peak of mating would occur in December 2021 and estimated calving would reach its peak in September 2022.

The purpose of the study: to study the medical and social aspects of the activities of public institutions of the city of Yekaterinodar in the early twentieth century, as a reflection of global trends shaping the public health system. Materials and methods: historical-descriptive, comparative-historical, problem-chronological, biographical methods were used in the work. The article is based on published sources and archival materials available to the authors. Results. Currently, there is no doubt that the level of public health depends not only on the activities of medical institutions, the qualifications of doctors, medical staff, but also on the timely comprehensive solution of many social issues with the participation of public and state institutions. The article presents some examples of the formation of such interaction and original solutions to urgent medical and social problems in Yekaterinodar (now Krasnodar) at the end of the XIX – beginning of the XX century. The issues of financing medical institutions, medical salaries and pensions, the organization of measures to combat epidemics, the formation of sanitary services, the opening of new specialized hospital departments, and services for the poorest segments of the population were touched upon. The elements of educational work, ways to solve the problem of high infant mortality and the organization of the first Consultation for infants are shown. Many doctors actively participated in the work of local city government, being “public” of the City Duma and the City Council, thereby contributing to the solution of many social and medical issues, including problems of payment for treatment, different categories of the population and “hospital arrears”. Conclusion . Thus, without having a clear state concept and program for the development of healthcare, the city administration, together with the medical community, demonstrated the desire and possibility of jointly solving many medical and social problems of the city of Yekaterinodar. That is, during this period, the potential properties and understanding of the need for the development of the public health system and sphere were formed in the regional society.

Fracture Height Quantification from Vertical and Horizontal Section Fiber Measurements: A Comprehensive Study Using LF-DAS Measurements from HFTS-2 Data Set

Published: March 2024

Summary
Understanding fracture height growth is critical for optimizing hydraulic fracture treatments and field development. In recent years, low-frequency distributed acoustic sensing (LF-DAS) has become a popular tool for monitoring strain changes during hydraulic fracturing. While LF-DAS data from vertical monitoring wells (VMWs) can be used to determine fracture height, measurements from the vertical section of horizontal wells may have the potential to capture fracture height growth. The objectives of this study are (1) to apply three methods—(a) using the vertical section of horizontal fiber measurements, (b) using the vertical fiber measurements, and (c) using the horizontal section of horizontal fiber measurements—to determine the fracture height using the Hydraulic Fracturing Test Site 2 (HFTS-2) data set and (2) to demonstrate the reliability of using LF-DAS measurements from the vertical section of horizontal fibers for fracture height determination.
In an effort to determine the fracture height from the HFTS-2 data set using the three methods, we demonstrate the reliability of the height prediction using strain measurements in the vertical section of the horizontal monitoring well (VS-HMW). First, we analyze the measurements from the vertical section of the horizontal fiber (B3H) during the stimulation of the heel-most stages of the horizontal wells (B1H, B2H, and B4H). Second, we analyze the measurements from the VMW (B5PH) during the stimulations of B1H, B2H, and B4H. Third, we use a geomechanical inversion algorithm to obtain height estimates from the horizontal section of the LF-DAS measurements at B3H during B1H, B2H, and B4H stimulations.
The fracture height is determined based on the transition of the extension-compression zone in the LF-DAS measurements from the vertical sections. The height estimates obtained using the three methods are compared and found to be consistent in the six well pairs we analyzed. The LF-DAS measurements from the vertical well B5PH provide a complete height profile, while measurements from the vertical section capture fracture growth from the upper tip of the fracture to the landing depth of the horizontal well. The fracture height estimates obtained from our inversion algorithm represent the average height value of all fracture hits at the chosen stage. This study demonstrates the potential to determine fracture height growth using LF-DAS measurements in the vertical section of a horizontal well, thus avoiding the cost associated with drilling VMWs to obtain fracture heights.
Fifty shades of purple: a contribution to mega-disaster economics
Authors: Dulac Guillaume 
Published: March 2024

Abstract
The orthodox economic framework stumbles in the analysis of mega-disasters’ specific features. We impute this to a variety of theoretical and practical issues, notably an invariable recourse to the expected value metric and its decoupling from time discounting. After providing an account of these shortcomings (2), we develop a two-pronged quantitative approach to address them: first we introduce a family of discount models (Lomax based) bridging the gap between the exponential and the hyperbolic discount models (3). We then define a functional, the Δ-transform, that bonds the discount model with the underlying random variable for disaster losses. Key properties of the Δ-transform are displayed along with a comparison to the orthodox framework in the case of exponential and Pareto distributions as emblematic representatives of light and heavy tailed phenomena. We find that the Δ-transform entails original features and addresses the key challenges identified in the diagnosis (4). We proceed alike with the Γ-transform, a natural variation of the Δ-transform, less conservative (5). In most cases the transforms entail a closed formula, using a variety of special functions. Last, we discuss the extent to which our new framework challenges conventional wisdom on mainstream disaster economics and other situations featuring long-term horizons and high uncertainty (6).

Abstract

Streptococcus pyogenes causes mild human infections as well as life-threatening invasive diseases. Since the mutations known to enhance virulence to date account for only half of the severe invasive infections, additional mechanisms/mutations need to be identified. Here, we conducted a genome-wide association study of emm89 S. pyogenes strains to comprehensively identify pathology-related bacterial genetic factors (SNPs, indels, genes, or k-mers). Japanese (n=311) and global (n=666) cohort studies of strains isolated from invasive or non-invasive infections revealed 17 and 1,075 SNPs/indels and 2 and 169 genes, respectively, that displayed associations with invasiveness. We validated one of them, a non-invasiveness-related point mutation, fhuB T218C, by structure predictions and introducing it into a severe invasive strain and confirmed that the mutant showed slower growth in human blood. Thus, we report novel mechanisms that convert emm89 S. pyogenes to an invasive phenotype and a platform for establishing novel treatments and prevention strategies.
Applications of Representation Learning Methods in Professional Baseball
Authors: Heaton Connor , Mitra Prasenjit 
Published: March 2024

Abstract

In the realm of sports analytics, players, teams, and managers have primarily been evaluated through a set of summary counting statistics. Typically, these statistics describe the number of times various events occurred on the field of play, perhaps dividing one quantity by another and/or applying some statistical adjustment. Recent works have proposed viewing the game as a sequence of events towards identifying specific items of interest, such as the players being in a certain formation on the field. However, this sequential, contextual understanding of the game is abandoned once the item of interest is identified. We speculate performance can be gained by leveraging this sequential, contextual understanding of the game. In this work we demonstrate how a rich, event-by-event understanding of a sport, in this case professional baseball, can provide utility in the tasks of player performance projection and clustering. In the process of doing so, we also demonstrate how findings in the domain of sports can translate to state-of-the-art advances in more traditional disciplines of study - specifically, the natural language processing task of emotion recognition in conversation (ERC) and the computer vision task of long-tail partial-label-learning (LT-PLL).

Abstract

Improvements in high-resolution satellite remote sensing and computational advancements have sped up the development of global datasets that delineate urban land, crucial for understanding climate risks in our increasingly urbanizing world. Here, we analyze urban land cover patterns across spatiotemporal scales from several such current-generation products. While all the datasets show a rapidly urbanizing world, with global urban land nearly tripling between 1985 and 2015, there are substantial discrepancies in urban land area estimates among them influenced by scale, differing urban definitions, and methodologies. We discuss the implications of these discrepancies for several use cases, including for monitoring urban climate risks and for modeling urbanization-induced impacts on weather and climate from regional to global scales. Our results demonstrate the importance of choosing fit for purpose datasets for examining specific aspects of historical, present, and future urbanization with implications for sustainable development, resource allocation, and quantification of climate impacts.
Chrono-EEG dynamics influencing hand gesture decoding: a 10-hours study

Published: March 2024

Abstract

Long-term electroencephalography (EEG) recordings have primarily been used to study resting-state fluctuations. These recordings provide valuable insights into various phenomena such as sleep stages, cognitive processes, and neurological disorders. However, this study explores a new angle, focusing for the first time on the evolving nature of EEG dynamics over time within the context of movement. Twenty-two healthy individuals were measured six times from 2 p.m. to 12 a.m. with intervals of two hours while performing four right-hand gestures. Analysis of movement-related cortical potentials (MRCPs) revealed a reduction in amplitude for the motor and post-motor potential during later hours of the day. Evaluation in source space displayed an increase in the activity of M1 of the contralateral hemisphere and the SMA of both hemispheres until 8 p.m. followed by a decline until midnight. Furthermore, we investigated how changes over time in MRCP dynamics affect the ability to decode motor information. This was achieved by developing classification schemes to assess performance across different scenarios. The observed variations in classification accuracies over time strongly indicate the need for adaptive decoders. Such adaptive decoders would be instrumental in delivering robust results, essential for the practical application of BCIs during day and nighttime usage.

Abstract

MDCK cells are the preferred cell line for influenza vaccine production, and the tumorigenicity of this cell line is a major concern with respect to its safety for vaccine production. However, the effect of miRNAs on the tumorigenicity of MDCK cells is poorly understood. In this study, we performed high-throughput sequencing of miRNAs in four MDCK cell lines with different degrees of tumorigenicity. Thereafter, the functions of these differentially expressed miRNAs were explored by miRNA target gene prediction, and we identified miR-2779-x as a key miRNA that is involved in the tumorigenicity of MDCK cells. Overexpression of miR-2779-x could decreased the tumorigenicity of MDCK cells in vivo and vitro. Dual luciferase binding reporter assay and Western blotting showed that miR-2779-x targeted and inhibited Bak1 protein expression. The effect of miR-2779-x on the tumorigenicity of MDCK cells in vitro was evaluated by Cell Counting Kit-8, wound healing and transwell invasion assays. Overexpression of miR-2779-x decreased cell proliferation and migration but increased cell invasion. In conclusion, we obtained evidence for the involvement of miRNAs in the tumorigenic phenotype of MDCK cells and provided novel insight into the establishment of MDCK cell lines that lack tumorigenicity.

Abstract

Background
There are mixed findings in the literature regarding the association between HIV status and the risk of COVID-19 infection. Thus, we aimed to estimate the association between characteristics of HIV infection and the risk of COVID-19 Infection in a Chinese sample.
Methods
We conducted a cross-sectional survey of 1995 people living with HIV (PLWH) and 3503 HIV-negative adults in Ningbo, China. We compared the prevalence rates of the SARS-CoV-2 infection and the long nucleic acid conversion time (more than 2 weeks) among PLWH and HIV-negative participants, respectively. In addition, we explored the risk factors associated with SARS-CoV-2 infection and the long nucleic acid conversion time among the two groups.
Results
Overall, 1485/1995 (74.4%) PLWH and 2864/3503 (81.8%) HIV-negative people were infected with SARS-CoV-2. Among the SARS-CoV-2-infected participants, 437/1485 (29.4%) PLWH and 649/2864 (22.7%) HIV-negative people had the long nucleic acid conversion time. After controlling for the potential confounders, the rate of the SARS-CoV-2 infection was lower among the PLWH than the HIV-negative group (adjusted OR = 0.836, 95% CI = 0.706–0.990). However, PLWH had a significantly higher risk of the long nucleic acid conversion time after the SARS-CoV-2 infection (adjusted OR = 1.417, 95% CI = 1.176–1.707) than the HIV negative participants. Compared with those who did not receive ART, PLWH adults who received ART significantly had the increased risk of SARS-CoV-2 infection. Furthermore, HIV-negative participants receiving COVID-19 vaccines significantly displayed the decreased likelihood of the long nucleic acid conversion time after the SARS-CoV-2 infection.
Conclusions
Our study indicates that different HIV Infection status was significantly and differently associated with the SARS-CoV-2 infection and the long nucleic acid conversion time. However, the further studies are needed to confirm the effect of ART and COVID-19 vaccines on SARS-CoV-2 infection in PLWH.
