AdaStereo: An Efficient Domain-Adaptive Stereo Matching Approach

Recently, records on stereo matching benchmarks are constantly broken by end-to-end disparity networks. However, the domain adaptation ability of these deep models is quite limited. Addressing such problem, we present a novel domain-adaptive approach called AdaStereo that aims to align multi-level representations for deep stereo matching networks. Compared to previous methods, our AdaStereo realizes a more standard, complete and effective domain adaptation pipeline. Firstly, we propose a non-adversarial progressive color transfer algorithm for input image-level alignment. Secondly, we design an efficient parameter-free cost normalization layer for internal feature-level alignment. Lastly, a highly related auxiliary task, self-supervised occlusion-aware reconstruction is presented to narrow the gaps in output space. We perform intensive ablation studies and break-down comparisons to validate the effectiveness of each proposed module. With no extra inference overhead and only a slight increase in training complexity, our AdaStereo models achieve state-of-the-art cross-domain performance on multiple benchmarks, including KITTI, Middlebury, ETH3D and DrivingStereo, even outperforming some state-of-the-art disparity networks finetuned with target-domain ground-truths. Moreover, based on two additional evaluation metrics, the superiority of our domain-adaptive stereo matching pipeline is further uncovered from more perspectives. Finally, we demonstrate that our method is robust to various domain adaptation settings, and can be easily integrated into quick adaptation application scenarios and real-world deployments.

Effects of Personal Ability and Social Welfare on the Health of Rural-to-Urban Elderly Migrants: An Empirical Analysis from Jiangsu Province, China

This study aims to discuss the relationship between personal endowment and social welfare on the health status of the rural-to-urban elderly migrants. It constructed the theoretical framework of the health vulnerability of rural-to-urban elderly migrants. The health status of rural-to-urban elderly migrants was divided into three dimensions: physical health, mental health, and social adaptation. A total of 658 rural-to-urban elderly migrants in 12 cities of Jiangsu province were selected as samples for empirical test and analyzed the influence of individual endowments and social welfare on the health status of rural-to-urban elderly migrants and their differences. The result shows that personal ability affects the social adaptation ability of rural-to-urban elderly migrants, and social welfare has a significant influence on the physical and mental health of rural-to-urban elderly migrants. Lacking the learning ability of rural-to-urban elderly migrants in sample areas is the main factor that leads to their low social adaptation ability and the unequal social welfare and public services restricting the physiological and mental health status of rural-to-urban elderly migrants.

Building climate change adaptation indicator set for Moc Hoa district, Long An province

To date, work in the field of climate change adaptation has resulted in many strategies for adaptation. In Vietnam, there have been many climate change adaptation activities implemented but has not been evaluated fully on effectiveness so that we can modify or make a replica of them systematically. In order to evaluate the effectiveness of carried out climate change adaptation activities, it is necessary to assess the current status of climate change adaptation for each local. In this paper, a set of CCA status evaluation indicators was developed and appreciated for Moc Hoa district, Long An province, to support a comprehensive assessment of the adaptation ability of this study area, the validity of investment resources allocation, and vulnerability to expose suitable policies. This set includes three indicators which are natural environment resilience, climate change vulnerability and climate change risk mitigation. The results showed that the environmental resilience indicators and the risk mitigation indicators were arranged at the medium level, while the climate change vulnerability indicators were high.

Relationship between Attitude and Anxiety Related to Online Learning

Background: Online learning is not newest but recently fresh used mode in educational sector where it was difficult for every student to adopt it. Initially students were having a different attitude towards online learning and they were anxious about there academic curriculum. The study was conducted to assess their attitude and anxiety towards online classes and to see the correlation between attitude and anxiety of online learning. We know mid school student has good adaptation ability but then also it’s a very new for them where students were facing lots of problem and faced lots of challenges due to COVID-19 pandemic specially the student who belong to poor family, but in this difficult time, everyone is doing their best to acquire new skills, and it's getting easier to enroll in online classes and finish their academic sessions. Objective: 1. To assess the attitude and anxiety of online learning among students. 2. To correlate the attitude and anxiety of online learning among students. Methods: This study was based on a Quantitative research approach. Convenient sampling technique was used. The population was all mid-school students from selected school area consisted of 200 samples. And there was structured attitude and general anxiety scale were used. Results: The mid study shows positive attitude and mild anxiety where the correlation between the attitude and anxiety is negative as per analysis.

The Influence of Cooperative Learning Through Authentic Assessment-Based Jigsaw on Social Development of Early Childhood

The early childhood education system nowadays requires the use of authentic assessment in schools. Authentic assessment is an integrative method of assessing the learning process, reflective to the real-world situations, using varieties methods and holistic criteria to assess the cognitive, affective, and skills in early childhood. Social development occurs dominantly after physical, cognitive, and language developments. Based on the minimal developmental standard, many early-childhood children show substandard development in environment adaptation ability, self-managing ability, responsibility, ability to follow rules, sharing, respecting others, cooperation, toleration, and emotional expression. This study aims to identify the influence of cooperative learning through authentic assessment-based jigsaw in the social development of early childhood. This study uses a pre-test post-test design on 50 subjects aged 5-6 years old. The experiment was carried out in 4 stage with 4 learning sub-themes. Data collected with a 1-4 scale observation instrument to get quantitative data and analyzed using t-Test. Results from data analysis concluded that cooperative learning through authentic assessment-based jigsaw has a positive influence on social development in early childhood. We recommend the implementation of this method to optimize social development in early childhood.

Bioactive Metabolites Produced by Cyanobacteria for Growth Adaptation and their Pharmacological Properties

Cyanobacteria are the most abundant oxygenic photosynthetic organisms inhabiting various ecosystems on earth. As with all other photosynthetic organisms, cyanobacteria release oxygen as a byproduct during photosynthesis. In fact, some cyanobacterial species are involved in the global nitrogen cycles by fixing atmospheric nitrogen. Environmental factors influence the dynamic, physiological characteristics, and metabolic profiles of cyanobacteria, which results in their great adaptation ability to survive in diverse ecosystems. The evolution of these primitive bacteria resulted from the unique settings of photosynthetic machineries and the production of bioactive compounds. Specifically, bioactive compounds play roles as regulators to provide protection against extrinsic factors and act as intracellular signaling molecules to promote colonization. In addition to the roles of bioactive metabolites as indole alkaloids, terpenoids, mycosporine-like amino acids, non-ribosomal peptides, polyketides, ribosomal peptides, phenolic acid, flavonoids, vitamins, and antimetabolites for cyanobacterial survival in numerous habitats, which is the focus of this review, the bioactivities of these compounds for the treatment of various diseases are also discussed.

Survival rate, adaptation ability and carbon production and sequestration of 21 green oak (Quercusrotundifolia Lam.) provenances at Mounts of Saida (western Algeria)

Due to recent global changes, a substantial degradation of natural ecosystems in North Africa and difficulties of species regeneration have been observed. A comparison of 21 green oak (Quercus rotundifolia Lam.) provenances in different bioclimatic zones was carried out at two ecologically different stations in western Algeria. The main objectives of the study were to (a) assess the survival rate and development in the natural environment of young individuals who derive from it, (b) gain an understanding of the level of morphological variability and (c) explore the possibilities of adapting the different provenances of green oak in the west Algerian ecological regions. The field trial was established in 2008 at two sites. The average survival rate ten years after the establishment of the field trial was 38.50%, with a total height average of 122.95 cm, a dry epigeous biomass production of 0.0630 t/ha and a sequestered amount of atmospheric carbon (CO2) of 0.0859 t/ha. The green oak provenance (origin) of Zaccar from the Tellian Atlas group is distinguished by a higher survival rate and dryer epigeous than other origins. The variability of large regions of the country means that there are four areas in which varieties can show superiority in survival and biomass: those representing the Northern part of the Saharan Atlas, those of the high inner plains, those of the southern facade of the Tellian Atlas and finally those of the Saharan Atlas.

The arrival and spread of the European firebug Pyrrhocoris apterus in Australia as documented by citizen scientists

We present evidence of the recent introduction and quick spread of the European firebug Pyrrhocoris apterus in Australia, as documented on the citizen science platform iNaturalist. The first public record of the species was reported in December 2018 in the City of Brimbank (Melbourne, Victoria). Since then, the species distribution has quickly expanded into 15 local government areas surrounding this first observation, including areas in both Metropolitan Melbourne and regional Victoria. The number of records of the European firebug in Victoria has also seen a substantial increase, with a current tally of almost 100 observations in iNaturalist as of July 31st, 2021. The case of the European firebug in Australia adds to the list of examples of citizen scientists playing a key role in not only early detection of newly introduced species but in documenting their expansion across their non-native range. Citizen science presents an exciting opportunity to complement biosecurity efforts carried out by government agencies, which often lack resources to sufficiently fund detection and monitoring programs given the overwhelming number of current and potential invasive species. Recognising and supporting the invaluable contribution of citizen scientists to science and society can help reduce this gap by: (1) increasing the number of introduced species that are quickly detected; (2) gathering evidence of the species’ early expansion stage; and (3) prompting adequate monitoring and rapid management plans for potentially harmful species.Given the range expansion patterns of the European firebug worldwide, their adaptation ability, and future climate scenarios, we suspect this species will continue expanding beyond Victoria, including other parts of Australia, New Zealand, and the South Pacific. We firmly believe that most of the knowledge about how this expansion process continues to happen will be provided by citizen scientists.

The influence of physical exercise on college students’ mental health and social adaptability from the cognitive perspective

BACKGROUND: the relationship between physical exercise (PE) and mental health (MH) had been an important research topic in exercise psychology. With the development of society, the increasingly fierce social competition had put forward higher and higher requirements for college students’ social adaptability (SA). As members of the new era, college students were expected to not only have innovative knowledge concept, solid knowledge foundation, and healthy psychology, but also have the ability to adapt to the changes in the environment, know how to get along with others, and deal with problems alone. OBJECTIVE: this study aimed to evaluate the PE, MH, and SA of college students, and to analyze the internal relationships among PE, MH, and SA. METHODS: based on questionnaire survey, college students were randomly selected for investigation and the data were statistically processed. RESULTS: there were significant differences in the MH of students of different genders, majors, grades, and origins. There was a significant difference between the amount of exercise and the MH of college students. The amount of exercise was positively correlated with the MH level of college students, and there was also a positive correlation between PE and MH. The SA of the physical exercisers was average, but the SA of the non-physical exercisers was poor. There was a significant difference between the SA of the physical exercisers and the non-physical exercisers. There were significant differences in the SA between physical exercisers and non-physical exercisers of different genders, majors, grades, and origins. Physical exercisers who participated in team sports were more socially adaptable. There was no significant difference in the SA of physical exercisers of different genders, majors, and origins, and the SA of senior students was stronger. CONCLUSIONS: PE had a positive effect on college students’ MH and social adaptation ability. Colleges and universities could improve their MH and social adaptation ability by arranging appropriate PE.
