Climate change affects the agricultural sector, which has an impact on droughts or floods. Ecological agriculture is expected to be an adaptation method for reducing losses due to climate change. This study aims to describe the characteristics of farmers, ecological rice cultivation practices, and the relationship between the two parameters. The research in Kendayakan Village, Terisi District, Indramayu Regency, involved 60 farmers surveyed using accidental sampling techniques in February 2022. The data collected include farmer characteristics (age, education, land area, land ownership status), length of farming, sources of farming knowledge, participation in groups, and rice cultivation practices. Data on the application level of ecological agricultural practices were analyzed descriptively and tested usin the Spearman Rank correlation between farmer characteristic variables and rice cultivation practices. The results showed that farmers were of productive age, with a low level of formal education but experienced and active in local organizations. The level of application of farmers' ecological agriculture is moderate. The return of straw, tillage, and control of plant pests are the components of cultivation that are least following the principles of ecological agriculture. Internal factors of farmers that correlate with the components of ecological rice cultivation are age, education, length of farming, source of farming knowledge, and land ownership status.

Genetic improvement through intensive selection in broilers for economically important traits such as body weight, growth rate, feed efficiency, and carcass quality plays a role in increasing the productivity and efficiency of the broiler industry. Good maintenance management is needed by paying attention to the quantity and quality of feed as well as comfortable and controlled environmental conditions. The environmental factor that is often the focus of attention is the temperature of milieu. During the brooding period aged 0‒21 days, the Day Old Chick cannot regulate its body temperature perfectly and still influenced by ambient temperature. Therefore, it is necessary to study the effect of brooding temperature on the performance of broiler at PT New Hope Indonesia's customers, to find the problems in regulating brooding temperatures along with solutions, evaluations, and improvement plans. Observations were made for 21 days in a semi-closed house with a population of 22,000 Cobb strain broiler. The research method used is data recording observation. The primary data were average brooding temperature for 21 days, depletion rate, feed consumption, body weight, feed conversion ratio (FCR), and production index. There was a deviation in body weight and FCR at the age of 11‒14 days due to the restriction of the heater until the age of 14 days and the wind speed at night which was more than 0.3 ms-1. With the corrective action of wind speed regulation, an effective temperature close to the thermoneutral zone and optimal production performance was obtained until the end of the brooding period.

Published: September 2023

Traditional nata de coco fermentation often results in inconsistent nata thickness. From the producer's perspective, thin nata sheets are detrimental because most fermentation media will be wasted. The main cause of this condition may be that the microbial population in the starter culture is different in each batch. It is necessary to observe the cultured microbial community on various qualities of available thick and thin nata to design a better nata de coco starter culture. This study showed thick nata had more Komagataeibacter intermedius bacteria (pellicle forming) than thin nata. In traditional nata fermentation, K. intermedius always coexists with other microbes from the bacteria and yeast groups. Random Amplified Polymorphic DNA (RAPD) analysis indicated that the genetic diversity of bacteria was higher than that of the yeast group.

Published: September 2023

This study aims to investigate the influence of financial distress on accrual earnings management and real earnings management before and during the COVID-19 pandemic. Using a purposive sampling method, the study analyzed the sectors most impacted by the pandemic lockdown, including energy, transportation, and logistics companies, between 2018 and 2021. The total sample of 236 firm-year observation data points was analyzed in this study using regression analysis. The study finds that financially distressed firms tend to engage less in real earnings management before and during the COVID-19 pandemic. However, the study did not find a similar significant difference for accrual earnings management. This research contributes to the discussion of financial distress and earnings management by looking more closely to the company most affected by the pandemic. Real earnings management is more costly than accrual earnings management, and companies with financial distress may not have enough resources, especially during the pandemic, to maneuver their real business operations.

Abstract

Perceptual updating has been proposed to rely upon evolving activity within a recurrent, distributed thalamocortical network whose interconnections are modulated by bursts of ascending neuromodulatory neurotransmitters, such as noradrenaline. To test this hypothesis mechanistically, we leveraged a combination of pupillometry, fMRI and recurrent neural network modelling of an ambiguous figures task. Qualitative shifts in the perceptual interpretation of an ambiguous image were associated with peaks in pupil diameter, an indirect readout of phasic bursts in neuromodulatory tone. We hypothesized that increases in neuromodulatory tone led to neural gain alteration so as to causally mediate perceptual switches. To test this hypothesis, we trained a recurrent neural network to perform an analogous perceptual categorisation task, and then manipulated the gain of the RNN to mimic the effect of neuromodulatory tone. As predicted, we observed an earlier perceptual shift as a function of heightened gain. Leveraging a low-dimensional readout of the RNN dynamics, we developed two novel predictions: perceptual switches should co-occur with peaks in low-dimensional brain state velocity and with flattened energy landscape dynamics. We used dimensionality-reduced summaries of whole-brain fMRI dynamics to independently confirm each of these predictions. These results support the role of the neuromodulatory system in the large-scale network reconfigurations that mediate abrupt changes in perception.

Abstract
Purpose:
This abstract examines stigma and attitudes towards mental illnesses among undergraduate students at Johannian universities. The study aims to evaluate the extent of stigmatization and associated factors.
Methods:
Three online questionnaires assessed depression, generalized anxiety disorder (GAD), and schizophrenia. Demographic data were collected via a Google Form from undergraduate students. Measures included age, gender, social status, personal and perceived stigma scales, social distance preferences, sources of information about mental illness, interventions, and supporting data.
Results:
A total of 1161 responses were collected, with 384 responses for the depression survey, 382 for the schizophrenia survey, and 395 for the GAD survey. Among the respondents, 57.7% were female, 29% were first-year college students, and 57% were medical students. Notably, 40% of participants had a history of mental illness, but only 0.04% had received psychological treatment. Websites and books were the most frequently mentioned sources of knowledge about mental health (79.4% and 73.7%, respectively). Statistically significant correlations between gender and population stigma were found in the surveys on depression and GAD, as well as depression and schizophrenia. Moreover, variations in personal opinions were observed based on gender in surveys on schizophrenia and depression, and between medical and non-medical students in surveys on depression and GAD.
Conclusions:
The study reveals a significant stigma among undergraduate students at Johannian universities towards individuals with mental illnesses, leading to a desire for social distance. To mitigate this stigma, anti-stigma programs should be implemented that promote societal acceptance and provide scientific information about mental illness.
Training high-functioning children with ASD in solving conceptual analogies with a neurofeedback-based protocol
Authors: Passig David , Naim Israel 
Published: September 2023

AbstractPurpose This study examined whether solving abstract analogies based on a neurofeedback procedure usingBrain-Computer-Interface(BCI) can improve the capability of abstract analogical reasoning in high-functioning children with ASD. Method 57 higher-functioning children with ASD, aged 6–9, participated in the study. They were familiar with basic abstract analogies. We randomly divided them into three groups: 18 practiced analogies using a BCI protocol we developed, 19 studied analogies with a tablet or a laptop (multimedia interfaces), and 20 others served as the control group and did not practice analogies. Results We found that practicing conceptual analogies using multimedia and BCI improved children’s achievements in learning conceptual analogies. The group that used the BCI showed the most significant improvement in their “spoken language ability” category and specifically in the sub-domains named ‘difference,’ ‘categories,’ and ‘descriptions.’ The group that practiced analogies with multimedia interfaces showed the most significant improvement in their “spoken language ability” in a sub-domain named ‘similarity.’ Conclusion This study may draw implications for learning conceptual analogies through BCI and MI. As the research indicates, practicing using these means improves the achievements of children with ASD in their ability to reason conceptual analogies and their ability to improve speech/spoken language.

Abstract
The acquisition of multi-dimensional optical information, including light intensity, spectrum, polarization, and phase, is a crucial aspect in the advancement of next-generation infrared photodetectors. However, the acquisition of multi-dimensional optical information on a single photodetector presents a significant challenge. Here, we present a multi-dimensional infrared optical information photodetector based on van der Waals heterojunction. It can obtain dual-band information (2.5–4.2 µm and 4.3–4.9 µm) and the polarization state of the target by adjusting the bias polarity. The device employs two anisotropic narrow bandgap semiconductors (black phosphorus and black arsenic phosphorus) and a wide bandgap semiconductor (molybdenum disulfide) to form a PNP-type van der Waals heterojunction. By controlling the thickness and stacking angle of the two anisotropic materials, selective absorption of incident light of different wavelengths and different polarization states is achieved. As a result, our device exhibits a dual-band response by changing the polarity of applied bias, allowing for polarization detection in both spectral ranges. The blackbody detection sensitivity of the device in the mid-wave infrared region is over 1×1010 cmHz1/2W-1 at room temperature. Its polarization extinction ratio reaches 24.7 under forward bias and 11.8 under reverse bias. This work shows promise in the development of next-generation of infrared photodetectors capable of acquiring multi-dimensional information.
Export unit value across markets: dampened by export subsidies
Authors: Nakhoda Aadil 
Published: September 2023

Abstract
The export unit value is influenced by the characteristics of the export market destination. However, this influence is dampened when export subsidies are provided by the government on specific products to incentivize the exporters. We use firm-level data on Pakistani exporters merged with product-level data on the provision of export subsidies in this study. We find that the provision of export subsidies on the products exported dampens this relationship as some of the export market characteristics that otherwise influence export unit value become insignificant. We split the sample of firms according to the product classification of the products exported, such as differentiated industrial products and homogenous non-industrial products, and the size of total export sales to determine whether the provision of export subsidies dampens the impact of export market characteristics on export unit value across the different product classifications as well as across larger and smaller exporters. We believe that the results have implications for policymakers providing incentives to the exporters.

Abstract
The palm Euterpe edulis Martius is native to the Atlantic Forest. The nutritional composition and antioxidant potential of its fruits are superior to those of Euterpe oleracea and Euterpe precatoria. The present study aimed to analyze the antioxidant defenses associated with in vitro germination of E. edulis and the quality of its seedlings. Seeds were harvested at 29 maturation stages (94–290 days after anthesis, DAA), and characterized in terms of budding, vigor, seedling formation, antioxidant defenses (superoxide dismutase, catalase, ascorbate peroxidase, and anthocyanins), hydrogen peroxide, lipid peroxidation, and hormonal composition. Fruit dry mass and volume did not differ from 241 DAA; whereas seed dry mass peaked 255 DAA, decreasing after this period. Seed moisture decreased throughout maturation. Seedling-related variables achieved the highest average values 227 DAA. The seeds showed maximum germination, vigor, percentage of normal seedlings, concentration of ZEA and ABA at 164 DAA. From 269 DAA, a decrease in dry mass suggested increased reserve consumption (respiration), inhibition of nutrient translocation to seeds, and reduction in water content (desiccation). The resulting greater sensitivity to environmental variations coincided with increased oxidative stress, but was counteracted by antioxidant defenses.

Published: September 2023

Abstract
Rotate vector (RV) reducers are typical deceleration elements with the outstanding characteristics of small size, compact structure, strong load-bearing capacity, and low transmission error, which are widely applied in fields of industrial robots, aerospace, and measurement instruments. The cycloidal gear, as the core component of the second-stage drive in RV reducer, its tooth profile directly determines the general performance of RV reducer such as meshing precision, load-bearing capacity, and riding stability. Therefore, it is necessary to explore and propose feasible methods and parameters for modification of cycloidal tooth profile. In this paper, taking the CRV-20E reducer as an object, firstly, a theoretical model for maximum contact stress and load distribution coefficient on meshing surfaces was established. Based on genetic algorithm, a multi-objective optimization for cycloidal profile was proposed with maximum contact stress and load distribution coefficient as objective functions, and the optimal combination of modification parameters was obtained. Secondly, with the idea of piecewise and the spline interpolation method, the cycloidal profile was separated into three segments of dedendum, working, and addendum. It ensured the conjugated meshing between cycloidal and pin tooth profile during working segment, besides, it remained various clearances in dedendum and addendum according to specific requirements. Finally, finite element simulation analysis was conducted on cycloid-pin gear drive mechanism, which containing for both two types of modified tooth profile, respectively. The simulation results verified the correctness of theoretical model and the feasibility of the proposed two modification methods.

Published: September 2023

Abstract
Etravirine (ERVN) is a potential NNRTI (non-nucleoside reverse transcriptase inhibitor) in treating HIV infection. It possesses extremely low oral bioavailability. The present research aims to optimize the formulation and characterization of TPGS-enriched ERVN-loaded lipid-based nanocarriers (LNCs) for HIV-infected patients. The formulation, ERVN-TPGS-LNCs, was optimized by CCRD using a modified-solvent evaporation process. Various characterization parameters of LNCs were evaluated, including globule size of 121.56 ± 2.174 nm, PDI of 0.172 ± 0.042, the zeta potential of -7.32 ± 0.021 mV, %EE of 94.42 ± 8.65% of ETR and %DL was 8.94 ± 0.759% of ERVN and spherical shape was revealed by TEM. PXRD was also performed to identify the crystallinity of the sample. In-vitro drug release showed % a cumulative drug release of 79.77 ± 8.35% at pH 1.2 and 83.23 ± 9.11% at pH 6.8, respectively, at the end of 48h compared to pure drug suspension (ERVN-S). Further, the intestinal permeation study and confocal microscope showed approximately ~3-fold and ~2-fold increased permeation in ERVN-TPGS-LNCs and ERVN-LNCs across the gut sac compared to ERVN-S. Hemolysis compatibility and lipolysis studies were performed to predict the in-vivo fate of the formulation. The pharmacokinetic study revealed a 3.13-fold increment in the relative bioavailability, which agrees with the ex-vivo studies, and lymphatic uptake was validated by using cycloheximide (CYHD) along with designed formulation, which leads to lowering AUC of ERVN-TPGS-LNCs. Thus, this study ensures that ERVN-TPGS-LNCs take lymphatic uptake to minimize the first-pass metabolism followed by improved oral bioavailability of EVN. Thus, the enhanced bioavailability of ERVN can reduce the high dose of ERVN to minimize the adverse effects related to dose-related burden.
