Journal's Global Impact Factor Records
The journal's Global Impact Factor (GIF) is calculated according to the standard formula published by Clarivate Analytics (previously ISI). The following is an example for calculation of 2022 GIF for regular issue.

A = 32 citations (number of times regular articles published in 2021 and 2020, cited in 2022).
B = 39 articles (total number of regular articles published in 2021 and 2020).
A/B = 0.821 (GIF of regular issue for 2022).

GIF for previous years were calculated using similar method and the value is announced in July of the relevant year. The journal was established in 2014.

NOTE: Raw data used in this calculation can be accessed from the journal’s citation records by Google Scholar for verifications by third parties.

GIF for 2021
A = 55 citations
B = 76 articles
GIF for 2021 = 0.724
H-Index = 13
= 23
GIF for 2020
A = 43 citations
B = 81 articles
GIF for 2019 = 0.531
H-Index = 10
= 15
GIF for 2019
A = 47 citations
B = 99 articles
GIF for 2018 = 0.475
H-Index = 7
= 3
GIF for 2018
A = 64 citations
B = 141 articles
GIF for 2017 = 0.454
H-Index = 6
= 1
GIF for 2017
A = 36 citations
B = 90 articles
GIF for 2017 = 0.400
H-Index = 4
= 0
IF for 2016
A = 6 citations
B = 20 articles
GIF for 2016 = 0.300
H-Index = 2
= 0

In silico analysis and structure modelling of heat shock protein HSP70 from Glaciozyma antarctica PI12 as a model system to understand adaptation strategies of Antarctic organisms amid adverse climates

Abstract The 70-kDa heat-shock proteins (HSP70) are integral components of the cell’s folding catalysts. Glaciozyma antarctica PI12 is an obligate psychrophilic yeast that possesses six HSP70 genes in its genome. The functions of these HSP70s in G. antarctica in terms of similarities and differences are yet to be discovered. The purpose of this study is to determine the structure and function of HSP70 from G. antarctica, which will lead to understanding this organism's adaptation strategies through structural and functional annotation. In this study, we utilize the HSP70 genes derived from genome data of Glaciozyma antarctica PI12 isolated from the Casey Research Station to characterize and compare structural characteristics which may contribute to their adaptation strategies during global warming. Computational tools such as Expasy’s ProtParam, MEGA 11, SWISS-MODEL, AlphaFold2, and SAVES were used to analyze all the genes via physicochemical analysis, phylogenetic study, homology modelling and structure validation, and superimposition of models. Results showed that reliable 3D models of HSP70 were successfully generated via the homology modelling approach using SWISS-MODEL and AlphaFold2 programs. The proposed model was evaluated as reliable with high confidence based on the structural stereochemical property, verification of protein patterns of non-bonded atomic interactions, compatibility of a 3D model with its amino acid sequence and determination of the protein's native fold. Among the new findings are the molecular signatures such as ionic, aromatic-aromatic, aromatic-sulphur and cation-pi interactions that are lesser in the buried residues when compared to their homologs. These interactions are important for maintaining structure stability, flexibility and packing in proteins. This may reflect the yeast response and adaptation strategies during the adverse climate. By studying the structural adaptations of HSP70 proteins in psychrophilic yeast, researchers can gain insights into how these proteins maintain their functionality in changing temperature conditions. This knowledge can inform the development of strategies to mitigate the impact of global warming on cold-adapted organisms and potentially guide the design of novel enzymes with improved thermal stability for biotechnological applications. In conclusion, this comprehensive study provides an in-depth understanding of the structural adaptation and evolution of HSP70 about their thermal resistance to global warming.

Herbs recognition based on chemical properties using machine learning algorithm
Nur Fadzilah Mohamad Radzi; Azura Che Soh; Asnor Juraiza Ishak; Mohd Khair Hassan. 2023. Transactions on Science and Technology, - in press.
Abstract For decades, the headspace Gas Chromatography Mass Spectrometry (GCMS) technique has been employed to analyse Volatile Organic Compounds (VOCs), extracting chromatographic signals and identifying chemical components. In practical scenarios, identifying major chemical compounds has been a useful approach for herb experts to recognize and differentiate species. However, this process has been manual and lacked an automated herb recognition system that incorporates GCMS technology. To address this gap, a GCMS herb recognition system has been proposed, integrating the GCMS system with a pattern recognition approach. Innovatively, a new feature extraction method using the Weighted Histogram Analysis Method (WHAM) has been introduced. This method employs a reweighting technique that utilizes the peak area and peak height of VOCs to generate a unique pattern for each herb species. A comparison of classification performance between systems with WHAM shows that the Support Vector Machine (SVM) method achieves a higher percentage of accuracy, ranging from 92.32% to 95.67%, compared to without WHAM, which achieves an accuracy ranging from 57.43% to 62.11%. This method has demonstrated promising results in identifying herb species, and the classification method based on machine learning algorithms has proven successful in recognizing and distinguishing herb species.
