Efficiency Enhanced Super Resolution Generative Adversarial Network via Advanced Knowledge Distillati

Hussain,신정훈,Syed Asif Raza Shah,조금원 한국멀티미디어학회 2023 멀티미디어학회논문지 Vol.26 No.12

Super-resolution (SR) stands as a prominent challenge in computer vision with diverse applications. Generative adversarial networks (GANs) yield impressive SR outcomes by restoring high-quality images from low-resolution input. However, GAN-based SR (particularly generators) have high memory demands, leading to performance degradation and energy consumption, making them unsuitable for resource-limited devices. Addressing this concern, our paper introduces a novel and efficient SR-GAN (generator) model architecture by strategically leveraging knowledge distillation, which results in reducing storage demands by 58% while enhancing performance. Our approach involves extracting feature maps from a resourceintensive model to design a lightweight model with minimal computational and memory requirements. Experiments across several benchmarks demonstrate that the proposed compressed model outperforms existing knowledge distillation-based techniques, particularly in regard to SSIM, PSNR, and overall image quality in x4 super-resolution tasks. In the future, this compressed model will be implemented and benchmarked with existing models in resource-limited devices such as tablet and wearing devices.

Background: The current study was designed to investigate the effect of supplementation of Flaxseed (Linumusitatisimum) oil on libido and semen quality of Nilli-Ravi buffalo bulls. Methods: In this study, 12 adult healthy bulls kept at the Semen Production Unit, Qadirabad district Sahiwal, were used. These bulls were divided into three equal groups, A, B and C. Group A was kept as control, while in groups B and C supplementation of feed was provided by using flaxseed oil @125 ml/day and 250 ml/day,respectively for 12 weeks. Two ejaculates per animal were collected at 0 day then 5th, 6th, 7th, 8th, 9th, 10th, 11th and 12th week of treatment. In this way a total 216 samples were taken, and each semen sample was evaluated for color, volume, mass activity, percent motility, sperm cell concentration per ml, percentage of live sperm, and plasma membrane integrity. Libido of bulls was also evaluated before every collection. Results: Analysis of data revealed that these parameters were significantly (P < 0.01) increased in flax oil treated animals as compared to control. Conclusion: It was concluded from the present study that flax seed oil has beneficial effects on reproductive health of buffalo bull.

Shah Hussain,Nhan Thi Nguyen,Xuan Canh Nguyen,임채오,정우식 한국식물생명공학회 2018 JOURNAL OF PLANT BIOTECHNOLOGY Vol.45 No.4

Post-translational modification of proteins regulates signaling cascades in eukaryotic system, including plants. Among these modifications, phosphorylation plays an important role in modulating the functional properties of proteins. Plants perceive environmental cues that directly affect the phosphorylation status of many target proteins. To determine the effect of environmentally induced phosphorylation in plants, in vivo methods must be developed. Various in vitro methods are available but, unlike in animals, there is no optimized methodology for detecting protein phosphorylation in planta. Therefore, in this study, a robust, and easy to handle Phos-Tag Mobility Shift Assay (PTMSA) is developed for the in vivo detection of protein phosphorylation in plants by empirical optimization of methods previously developed for animals. Initially, the detection of the phosphorylation status of target proteins using protocols directly adapted from animals failed. Therefore, we optimized the steps in the protocol, from protein migration to the transfer of proteins to PVDF membrane. Supplementing the electrophoresis running buffer with 5 mM NaHSO3 solved most of the problems in protein migration and transfer. The optimization of a fast and robust protocol that efficiently detects the phosphorylation status of plant proteins was successful. This protocol will be a valuable tool for plant scientists interested in the study of protein phosphorylation.

Pharmaceutical residues: New emerging contaminants and their mitigation by nano-photocatalysis

Shah, Aarif Hussain,Rather, Mushtaq Ahmad Techno-Press 2021 Advances in nano research Vol.10 No.4

The steady growth in population has led to an enhanced water demand and immense pressure on water resources. Pharmaceutical residues (PRs) are unused or non-assimilated medicines found in water supplies that originate from the human and animal consumption of antibiotics, antipyretics, analgesics etc. These have been detected recently in sewage effluents, surface water, ground water and even in drinking water. Due to their toxicity and potential hazard to the environment, humans and aquatic life, PRs are now categorized as the emerging contaminants (ECs). India figures in the top five manufacturers of medicines in the world and every third pill consumed in the world is produced in India. Present day conventional wastewater treatment methods are ineffective and don't eliminate them completely. The use of nanotechnology via advanced oxidation processes (AOP) is one of the most effective methods for the removal of these PRs. Present study is aimed at reviewing the presence of various PRs in water supplies and also to describe the process of AOP to overcome their threat. This study is also very important in view of World Health Organization report confirming more than 30 million cases of COVID-19 worldwide. This will lead to an alleviated use of antibiotics, antipyretics etc. and their subsequent occurrence in water bodies. Need of the hour is to devise a proper treatment strategy and a decision thereof by the policymakers to overcome the possible threat to the environment and health of humans and aquatic life.

Genome-wide identification and comparative analysis of MATE gene family in Cucurbitaceae species and their regulatory role in melon (Cucumis melo) under salt stress

Shah Iftikhar Hussain,Manzoor Muhammad Aamir,Sabir Irfan Ali,Ashraf Muhammad,Haq Fazal,Arif Samiah,Abdullah Muhammad,Niu Qingliang,Zhang Yidong 한국원예학회 2022 Horticulture, Environment, and Biotechnology Vol.63 No.4

The multidrug and toxic compound extrusion (MATE) protein family includes a primeval gene family of secondary transporters that export toxins, extrude metabolites, and participate in plant defense mechanisms. However, lack of information regarding the MATE gene family in Cucurbitaceae, a comprehensive genome-wide analysis of the MATE family was carried out in four Cucurbitaceae species (Cucumis melo, Cucumis sativus, Cucurbita pepo, and Lagenaria siceraria), and 174 MATE genes were identified. Phylogenetic and structural analysis revealed that the Cucurbitaceae MATE transporters family could be further classified into seven subgroups (A–G). GO annotation-based subcellular localization analysis predicted that most of the MATE gene family members localized on the plasma membrane. Moreover, conserved motifs and gene structure (intron/exon) analysis revealed the functional divergence between clades. Transposed duplication events have played a key role in the expansion and evolution of the MATE gene family in Cucumis melo. Cis-acting elements analysis of MATE family genes revealed that these could be targeted by a diverse set of trans-acting factors involving the MATE gene family to manage diverse stress conditions. The Chromosomal localization and molecular characteristics (weight, length, and pI) were performed using numerous bioinformatics tools. Intraspecies microsynteny analysis demonstrated that maximum orthologous genes were found between A. thaliana, C. pepo, C. lanatus, and L. siceraria. Further, functional analysis of microRNAs demonstrated miRNAs are involved in the growth and regulation of MATE genes. Finally, eleven candidates MATE genes were selected randomly, and their expression analysis was carried out via qRT-PCR at 0 h and after 24 h of salt stress. Furthermore, transient CmMATE expression in Arabidopsis thaliana protoplasts showed that protein localized on the plasma membrane. This study provides insights into the functional analysis of the MATE gene family in Cucurbitaceae species and laid down the basic knowledge to explore the role and mechanism of the MATE gene family to cope with severe salt stress conditions.
