Skeleton-Based Human Action Recognition with Global Context-Aware Attention LSTM Networks

Human action recognition in 3D skeleton sequences has attracted a lot of research attention. Recently, Long Short-Term Memory (LSTM) networks have shown promising performance in this task due to their strengths in modeling the dependencies and dynamics in sequential data. As not all skeletal joints are informative for action recognition, and the irrelevant joints often bring noise which can degrade the performance, we need to pay more attention to the informative ones. However, the original LSTM network does not have explicit attention ability. In this paper, we propose a new class of LSTM network, Global Context-Aware Attention LSTM (GCA-LSTM), for skeleton based action recognition. This network is capable of selectively focusing on the informative joints in each frame of each skeleton sequence by using a global context memory cell. To further improve the attention capability of our network, we also introduce a recurrent attention mechanism, with which the attention performance of the network can be enhanced progressively. Moreover, we propose a stepwise training scheme in order to train our network effectively. Our approach achieves state-of-the-art performance on five challenging benchmark datasets for skeleton based action recognition

An integrated review program for the preparation for the United States medical license examination (USMLE)

The primary objective of the present educational research program is to improve upon existing commercially available USMLE review programs. With the clear shortage of both residency slots, the medical student's performance (score), on the USMLE assumes a new and critical importance. Furthermore, there is a global need for 4.3 million new doctors and nurses. This shortage is particularly evident in Central and Southeast Asia. Many of the needed new doctors will most probably be required to pass the USMLE

Epshteyn-Barr virusini IFA usulida tashxislashning ahamiyati

Tadqiqot maqsadi: Epshteyn-Barr virusiga qarshi Anti-EBV IgM va Anti-EBV IgG ni IFA usulida tekshirish va antigen tahlilini o’tkazish. Material va usullari: Toshkent shahar, Yunusobod tumanidagi InterMed xususiy klinikasi 2022-yildagi materiallaridan foydalanildi. Tekshirish uchun bemorlar bilak venasidan 5 ml qon olindi va IFA (BektoВЭБ-VCA-IgG-IGM, D-2176, D-2184, АО «Вектор-Бест», Новосибирск) usulida tekshirildi. Olingan natijalar statistik tahlil qilindi. Natijalar tahlili va muhokamasi: Bemorlar Anti immunoglobulinlar bo’yicha tekshiruvdan o’tkazildi. Epshteyn-Barr virusi Anti immunoglobulinlar bo’yicha musbat natijalar eng koʻp foizda (34%) 10 yoshgacha boʻlgan bolalar oʻrtasida uchradi. Natijalar jins boʻyicha tahlil qilinganda Epshteyn-Barr virusi koʻproq ayollarda (55%) uchradi. Anti EBV IgM boʻyicha 33% manfiy, 12% musbat natijalar kuzatildi. Anti EBV IgG bo’yicha 34% musbat, 66% manfiy natija qayd qilindi. Xulosa: EBV qarshi Anti EBV IgM va Anti EBV IgG musbat natijalar eng koʻp foizda (34,0%) 10 yoshgacha boʻlgan qiz bolalar oʻrtasida musbat - yuqori ko’rsatkichlarda (55,0%) uchradi. Anti EBV IgM boʻyicha12% musbat natijalar kasallik o’tkir kechayotganligidan, Anti EBV IgG bo’yicha esa 34,0% musbat natija kasallikning surunkali kechayotganligidan dalolat berdi

The Situation of Food Security in Kazakhstan

The research aims to explore the current the food security situation in the Republic of Kazakhstan. To accomplish this objective, the research examines some of the critical theoretical and practical aspects of food security in the nation. The findings reveal that when compared with other nations, in the period under analysis the food security level in Kazakhstan has increased reaching the world level. However, there remain many unresolved issues which are impeding progress. As part of the study, the authors conducted a survey by questionnaire designed to explore some of the key consumer motives and preferences underlying the choice of domestic or imported food products; assess the economic accessibility of food in a climate of rising prices and people’s declining purchasing power; to examinewhether, as a result of the economic crisis (2015-2016), most people in Kazakhstan have opted for running a private subsidiary plot or for stocking up on food. The authors propose a model of the organisational structure underlying the process of implementation of Kazakhstan’s strategy for boosting the competitiveness of the nation’s agriculture and ensuring its food security
