Complexes++: Efficient and versatile coarse-grained simulations of protein complexes and their dense solutions
Authors: Linke Max , Quoika Patrick , Bramas Berenger , Köfinger Jürgen , Hummer Gerhard
Published: July 2022

The interiors of living cells are densely filled with proteins and their complexes, which perform multitudes of biological functions. We use coarse-grained simulations to reach the system sizes and time scales needed to study protein complexes and their dense solutions, and to interpret experiments. To take full advantage of coarse-graining, the models have to be implemented efficiently in simulation engines that are easy to use, modify, and extend. Here, we introduce the Complexes++ simulation software to simulate a residue-level coarse-grained model for proteins and their complexes [Kim and Hummer, J. Mol. Biol. (2008)], applying a Markov chain Monte Carlo engine to sample configurations. We designed a parallelization scheme for the energy evaluation capable of simulating both dilute and dense systems efficiently. Additionally, we designed the software toolbox pycomplexes to easily set up complex topologies of multi-protein complexes and their solutions, different thermodynamic ensembles, and replica-exchange simulations, to grow flexible polypep- tide structures connecting ordered protein domains, and to automatically visualize structural ensembles. Complexes++ simulations can be easily modified and they can be used for efficient explorations of differ- ent simulation systems and settings. Thus, the Complexes++ software is well suited for the integration of experimental data and for method development.

Adoption of cashless transactions in SHGS: a case study in konaseema region, andhra pradesh
Authors: Sridevi V. , Yoginder Singh
Published: July 2022

Cashless transactions are common in business sectors and in cities to a large extent. But after the announcement of the demonetization of all Rs. 500 and Rs. 1,000 banknotes on November 8, 2016 by the Government of India, all the sectors to the maximum extent adopted cashless transactions. SHGs too have adopted this culture by installing mobile apps on their smart phones. During 2015-16, NABARD, through its project Eshakti digitisation of SHGs, has made an attempt to update the SHG bookkeeping on a real time basis to bring transparency and credibility. The project EShakti had the advantage of addressing the problem of book keeping through available technology, knowing the credit history of SHG members, generating grades for SHGs based on their financial and non-financial records and making them available to all important stakeholders. The stakeholders, namely bankers can now take informed decisions on extending credit linkages on the basis of reports generated through EShakti. In this paper, an attempt is made to study the adoption of cashless transactions in SHGs in the Konaseema region.

The Test of English as a Foreign Language (TOEFL) is a type of language test of which results are often used as a reference for new student admission in Universities. However, this test is not included in the English language learning curriculum at the secondary level so high school students are not familiar with it. Therefore, this community service activity aims at introducing the test to middle-level students so that they have knowledge and are familiar with the types of questions tested in this test. To determine the progress of students' knowledge and abilities, pre and post-tests were conducted, and the result was the improvement of the scores indicating that the learning approach chosen in this activity is in accordance with the objective of the training. In addition, a simple information system for test assessment was created using Microsoft Excel. This information system helps record student grades and makes it easier to convert TOEFL scores.

Dynamics of a Discrete-Time Chaotic Lü System
Authors: Rana Sarker Md. Sohel , Uddin Md. Jasim
Published: July 2022

A discrete-time chaotic Lü system is investigated. Firstly, we give the conditions of local stability of this system around feasible fixed points. Then, we show analytically that discretized Lü system undergoes a flip-Neimark Sacker (NS) bifurcation when one of the system parameter varies near its critical value. We confirm the existence of flip-NS bifurcation via explicit Flip-NS bifurcation criterion and determine the direction of both bifurcations with the help of center manifold theory and bifurcation theory. We carry out numerical simulations to affirm our analytical findings. Furthermore, we present Maximum Lyapunov exponents (MLEs) and Fractal dimension (FD) numerically in order to justify whether chaos exists in the system or not. At the end, we apply hybrid control strategy to eliminate chaotic trajectories of the system.
Slenderness in Steel Fibre Reinforced Concrete Long Beams
Authors: Kaur Ravpreet , Singh Harvinder
Published: July 2022

Slenderness influences in steel fibre reinforced concrete (SFRC) long beams are not adequately addressed in current concrete design regulations. The present guidelines are confined to semi-empirical formulations for limiting slenderness ratio, but largely restricted to RC beams. Many scholars have already examined RC long beams and successfully presented the slenderness ratio formula for RC long beams. This article proposes a novel term for limiting the slenderness ratio for SFRC long rectangular beams based on the fundamental principle of mechanics and taking into account the slenderness impact of RC long beams as well as the flexural moment capacity of SFRC beams. The suggested formulation for limiting slenderness ratio agrees closely with experimental data and may reliably forecast the mode of collapse. The proposed limiting slenderness ratio formulation takes into consideration beam end circumstances, loading conditions, concrete strengths, steel, tension and compression reinforcement ratios, and transverse reinforcement ratios, among other factors. It is revealed that a wide variety of slenderness limits may be achieved for varied sets of design parameters. The researchers' predictions and the suggested equation are compared to the test results of 9 SFRC beams. The suggested equation fits well with the results of the tests that have been done so far. Doi: 10.28991/CEJ-2022-08-06-011 Full Text: PDF
Impact of Climate Change on Crops Productivity Using MODIS-NDVI Time Series

Published: July 2022

Climate change is the single biggest threat facing the global food system. Irrefutable impacts of climate change on the food systems are recently acknowledged. Therefore, extensive scientific efforts around the globe are dedicated to investigating and evaluating the short and long-term effects of climate change on the development of global food systems. In this study, an integrated approach of two methodologies, including Moderate Resolution Imaging Spectroradiometer (MODIS) Data and Normalized Difference Vegetation Index (NDVI), was employed to extrapolate the long-term changes in agronomic areas from 2000 to 2020 in the Dukan Dam Watershed (DDW), Northern Iraq. The link between agricultural areas and the primary production of essential crops (Wheat, Barley, Rice, Maize, and Sunflower) is proposed to be altered due to the impact of climate change. According to the Intergovernmental Panel on Climate Change (IPCC) report, Iraq is one of the semi-arid regions in the world that has recently been characterized by water scarcity and limited agronomic areas. Three independent variables (rainfall, temperature, and agriculture area) were used in the multiple regression analysis to understand the impact of the main drivers affecting the production of crops in DDW. Obtained results showed an increasing trend in crop production as a result of the frequent use of groundwater and surface water sources along with the implementation of greenhouse cultivation. Correlation analysis shows that the crop production was significantly related to the annual precipitation with a 59–63% in winter crops like wheat and barley, but was less sensitive to the temperature with a 20–40% in summer crops like rice, maize, and sunflower. Doi: 10.28991/CEJ-2022-08-06-04 Full Text: PDF

Published: July 2022

The issue of ensuring the economic security of Russia has always been the most acute, but in the new realities of 2022 it has become the most relevant. The "Dutch disease" of the Russian economy, the disruption of supply chains, import substitution under sanctions pressure are the main problems in the context of Western European pressure on Russian business. The ability to maneuver and quickly adapt industries, industries and the entire complex of the manufacturing industry is the basis of national economic security in the context of international sanctions, regardless of how justified they are.
