Performance comparison of fixed and single axis tracker photovoltaic system in large scale solar power plants in Malaysia
Authors: Mahmoud Dawoud Baraa , Chun Lim Siow 
Published: January 2021

<span>Malaysia is rapidly expanding the generation capacity of solar power through large scale solar (LSS) projects with the aim to achieve 20% renewable energy mix by 2025. This has motivated many solar industry players to explore the usage of solar PV with single axis tracker (SAT) system. However, many are still hesitant due to the lack of understanding on the comparative performance between fixed mounted solar PV with solar PV with SAT system. This paper aims to provide a comparative analysis on the performance of both systems. Simulation using PVSyst 6.83 was performed in five potential LSS sites spread across Peninsular Malaysia in Perlis, Kelantan, Pahang, Selangor and Johor with the same installed capacity of 10.32MWp. The energy yield and capacity factor for 21 years were simulated. On the average, it was found that SAT outperforms fixed mounted solar PV system by 15.08% based on their performance on their first year operation. </span>
Probing signals with ZACZ for GPRonboard of unmanned aerial vehicle

Published: January 2021

<p><span>Modern ground penetrating radars (</span><span>GPR</span><span>), designed to determine the thickness of ice or search for the occurrence of aquifers in arid regions of the Earth, are installed either on helicopters or on the earth's surface. The use of a helicopter is economically expensive, and the installation of GPRs on the earth's surface is of a local nature. Modern GPRs mainly use video pulse probing signals and probing signals with linear frequency modulation. These signals have correlation noise, which makes it difficult to obtain a high-quality radar image. In this work, we propose to use a signal with a zero autocorrelation zone (ZACZ) as a probing signal for GPR installed on an unmanned aerial vehicle. In work, a polyphase probing signal with a ZACZ is synthesized and a comparative analysis of the correlation characteristics of the synthesized signal with the optimal phase-code shift keyed signal is carried out. </span></p>
Compressed domain based robust digital video watermarking scheme to protect the copyright

Published: January 2021

<p><span>Digital video watermarking is an effective way to protect the ownership of the multimedia contents. A novel compressed domain based digital video watermarking algorithm scheme is proposed by exploiting MPEG-2 structure. Watermark bits are embedded in DC and AC coefficients both of only smooth discrete cosine transform (DCT) blocks from selected I-frames in the original digital video. The algorithms never exploited entire frames but explore only three location from the subset of DCT blocks from the subgroup of I-frames only. This process maintains the perceptibility of the watermarked video. Two parameters, normalized correlation (NC) and bit error rate (BER) are used to evaluate the degree of similarity and dissimilarity respectively to check the robustness against image processing and video specific intentional and non-intentional attacks. The security of embedded watermark is enhanced by applying three cryptographic keys. The experimental results demonstrated that the better robustness and perceptibility achieved by comparing the results with the state of art. </span></p>

Published: January 2021

<span>This paper presents the FPGA-based implementation of compact montgomery modular multiplier (MMM). MMM serves as a building block commonly required in security protocols relying on public key encryption. The proposed design is intended for hardware applications of lightweight cryptographic modules that is utilized for the system on chip (SoC) and internet of things (IoT) devices. The proposed design is a modification in the structure of MMM without any multiplication or subtraction processes. The main target of the new modification is enhancing the performance and reducing the area of the MMM hardware module. The operands and internal variables of the proposed hardware circuit is optimized to be bounded to the smallest efficient size to minimize the area and the critical path delay. The proposed design was coded in VHDL, implemented in the Virtex-6 FPGA, and its performance was analyzed utilizing XILINX ISE tools. Our design occupies the smallest area comparing with other implementations on the same FPGA type. The proposed design saves in a range between 60.0 and 99.0% of the resources compared with other relevant designs.</span>

apport de l’épistémologie de René Thom à la sémiotique
Authors: Wildgen Wolfgang 
Published: January 2021

La pensée épistémologique de René Thom montre deux facettes qui correspondent grossièrement à deux périodes de sa recherche scientifique : (a) un platonisme mathématique qui recherche le corrélat des structures topologiques dans la réalité des phénomènes (la période de 1965 à 1977), et (b) la critique du paradigme galiléen en physique expérimentale et la pertinence d’une philosophie de la nature appliquée à la biologie et à la sémiotique (la période de 1978 à 1990). Les deux positions peuvent être analysées d’une part en partant du livre Stabilité structurelle et morphogenèse de 1972 et de son programme d’une analyse qualitative basée sur la théorie des catastrophes (ensemble avec Christopher Zeeman), d’autre part basé sur le livre de 1988 avec la vision d’une sémiophysique et un programme qui se met à la recherche des forces qui sélectionnent et canalisent la morphogenèse du sens (et qui permettent de constituer une sémantique en linguistique et une sémiotique dynamique). L’épistémologie de Thom peut être interprétée dans le contexte de la tradition philosophique de Leibniz à Kant et Husserl. Jean Petitot explique les rapports tout en considérant la sémiotique de Greimas et les recherches cognitives en linguistique et en neuropsychologie. Ces aspects historiques sont discutés brièvement. Cet article essaie de clarifier et d’évaluer la portée épistémologique des travaux de Thom pour la sémiotique et la linguistique. Il poursuit le but non seulement de faire comprendre cette contribution au débat épistémologique, mais aussi de circonscrire le potentiel épistémologique de la pensée morphodynamique de René Thom pour la sémiotique et la linguistique.
Naturalité de la catégorisation sémiotique: de la genèse perceptuelle à la déférence sémantique à l’égard du référent
Authors: Leclercq Bruno 
Published: January 2021

En revenant « aux sources (naturelles) du sens », les Principia Semiotica du Groupe µ jettent un solide pavé dans la mare de toute une tradition sémiologique qui, partant des textes linguistiques (puis visuels), avait plutôt insisté sur la grande inventivité et la grande diversité culturelle des systèmes de signes. En soulignant la dimension résolument naturelle et motivée de la sémiose, le Groupe µ s’en prend frontalement à un certain « axiome de conventionalité » dominant dans la sémiologie contemporaine, notamment dans son paradigme structuraliste. Par le même geste, le Groupe µ s’en prend aussi en droite ligne à une épistémologie d’« idéalisme linguistique (ou plus généralement symbolique) », qui s’est imposée dans la seconde moitié du XXème siècle sous l’influence d’un certain « tournant linguistique » et qui a vu, dans les catégorisations conventionnelles, la source de toute sémiose mais aussi de toute production de connaissance. Par son attention aux sources perceptuelles de la sémiose la plus originaire, le Groupe µ réhabilite tout à la fois une certaine épistémologie réaliste, qui estime que le monde est déjà organisé avant sa structuration dans telle ou telle langue et qu’il motive même cette structuration, et une certaine épistémologie empiriste, qui voit dans l’expérience sensible le lieu de cette motivation et dès lors la source première de la sémiose et de la connaissance. En insistant sur la continuité des processus cognitifs naturels qui régissent cette sémiose avec d’autres dispositifs matériels présents dans le monde animal ou même vivant, la sémiogénétique s’avère aussi solidaire d’une épistémologie plus naturaliste et matérialiste que culturaliste et « glossocentriste ». Reste toutefois que les étapes ultérieures de la sémiose (avec la fonction de renvoi propre à la sémiose indirecte ou l’interprétation propre à la sémiose consciente) rendent, pour le Groupe µ, toute sa place à une sémiose intersubjective plus arbitraire et culturellement dépendante. À partir de nos propres travaux sur la déférence sémantique, nous montrons cependant que la division du travail linguistique, qui garantit cette intersubjectivité du sens, n’implique pas forcément la conventionalité qu’on lui associe généralement, mais qu’elle peut elle aussi, pour certains signes au moins, être liée à une épistémologie réaliste qui s’attache à la motivation naturelle plutôt qu’à l’arbitraire conventionnel de la sémiose.
The Relationship between Three Short Indigenous Chinese Buddhist Scriptures and the Textual Practices Found in their Dunhuang Manuscript Colophons
Authors: Chen Ruifeng 
Published: January 2021

Abstract
This article studies the relationship between colophons for, and the content of, Dunhuang manuscripts of three indigenous Chinese Buddhist scriptures: the Jiu zhuzhongsheng kunan jing, the Xin pusa jing, and the Quanshan jing. I find that the aspirations for copying these scriptures and the ways of using them are mostly consistent with their content. The patrons or users of these scriptures seem to have largely understood their content. Also, the similarities in the content, and the length of the Jiu zhuzhongsheng kunan jing and the Xin pusa jing should be two factors that account for why these scriptures were frequently copied as one set. Concerns for one’s own family and the relevant instructions in the texts may have led patrons to prefer to copy the Xin pusa jing twice, but the other two scriptures only once as a single scribal act.

Published: January 2021

Abstract
Background
Ovarian cancer is one of the deadliest gynecological malignancies. While the overall survival of ovarian cancer patients has slightly improved in recent years in the developed world, it remains clinically challenging due to its frequent late diagnosis and the lack of reliable diagnostic and/or prognostic markers. The aim of this study was to identify potential new molecular target proteins (NMTPs) responsible for the poor outcomes. When nanoparticles (NP) are exposed to biological fluids, a protein coat, termed the protein corona (PC), forms around the NP, and the PC represents a tool to identify NMTPs. This study investigates the influence of pre-processing conditions, such as lysis conditions and serum/plasma treatment, on the PC composition and the resulting identification of NMTPs.

Results
Using gel electrophoresis, pre-processing conditions, including cell-lysis techniques and enrichment of low-abundance proteins (LAPs) by immunocentrifugation of serum/plasma, were shown to alter the relative amounts and compositions of proteins. PCs formed when 20 nm gold-NPs (GNPs) were incubated with lysate proteins from either RIPA- or urea lysis. Proteomic analysis of these PCs showed 2–22-fold enrichment of NMTPs in PCs from urea lysates as compared to RIPA lysates. Enriched NMTPs were then classified as cellular components, biological and molecular functions-associated proteins. The impact of enriched LAPs (eLAPs) on both PC composition and NMTP identification was shown by comparative proteomic analysis of original plasma, eLAPs, and PCs derived from eLAPs; eLAPs-PCs enhanced the abundance of NMTPs approximately 13%. Several NMTPs, including gasdermin-B, dermcidin, and kallistatin, were identified by this method demonstrating the potential use of this PC approach for molecular target discovery.

Conclusion
The current study showed that the pre-processing conditions modulate PC composition and can be used to enhance identification of NMTPs.
What a weight loss programme should contain if people with obesity were asked - a qualitative analysis within the DO:IT study
Authors: Jessen-Winge Christina , Ilvig Pia Maria , Fritz Heather , Brandt Carl J. , Lee Kim , Christensen Jeanette Reffstrup 
Published: January 2021

AbstractBackgroundCurrently 1.9 billion adults worldwide are estimated to be overweight or obese. In Denmark the municipalities hold the responsibility to deliver weight loss programmes to overweight and obese citizens. There is a tendency to assume that weight loss programmes that show positive effects in specialized hospital settings are directly transferrable to municipal settings. However, municipality-based weight loss programmes have not produced clinically significant reductions in body weight. One reason for this may be that much research evidence regarding obesity programming neglects the perspectives of people with obesity. The first step in developing a weight loss programme designed for municipal settings is to understand what people with obesity want and need from a programme. The aim of this study was to examine what people with obesity find important in a weight loss programme for weight loss and weight maintenance.MethodsWe used a qualitative, explorative, descriptive design with individual interviews. We included men and women age 17 and older with a BMI ≥ 25 kg/m2. Participants were recruited from the wait lists of 13 municipality programmes and through Facebook posts. Data were analyzed using content analysis.ResultsThirty-four participants with overweight or obesity were individually interviewed (ages between 19 and 74). Findings suggest that weight loss programmes should; a) support participants in structuring days; b) consider the use of replacement activities to reduce cognitive and emotional burden; c) aide individuals to increase self-efficacy and; d) include family and friends as well as health professionals and peers in the weight loss process. Diet and exercise, while important, should be balanced with other meaningful activities in everyday life.ConclusionParticipants in this study wished to balance weight loss related activities with overall everyday life as well as finding the believe in their ability to lose weight in social relations.
Efficacy and safety of Si-Jun-Zi-Tang-based therapies for functional (non-ulcer) dyspepsia: a meta-analysis of randomized controlled trials
Authors: Wang Yaping , Liu Bin , Fu Xiuqiong , Tong Tiejun , Yu Zhiling 
Published: January 2021

Abstract
Background
The traditional Chinese medicine formula Si-Jun-Zi-Tang (SJZT) has a long history of application in the treatment of functional dyspepsia (non-ulcer dyspepsia, FD)-like symptoms. SJZT-based therapies have been claimed to be beneficial in managing FD. This study aimed to assess the efficacy and safety of SJZT-based therapies in treating FD by meta-analysis.

Methods
Systematic searches for RCTs were conducted in seven databases (up to February 2019) without language restrictions. Data were analyzed using Cochrane RevMan software version 5.3.0 and Stata software version 13.1, and reported as relative risk (RR) or odds ratio (OR) with 95% confidence intervals (CIs). The primary outcome was response rate and the secondary outcomes were gastric emptying, quality of life, adverse effects and relapse rate. The quality of evidence was evaluated according to criteria from the Cochrane risk of bias.

Results
A total of 341 potentially relevant publications were identified, and 12 RCTs were eligible for inclusion. For the response rate, there was a statically significant benefit in favor of SJZT-based therapies (RR = 1.23; 95% CI 1.17 to 1.30). However, the benefit was limited to modified SJZT (MSJZT). The relapse rate of FD patients received SJZT-based therapies was lower than that of patients who received conventional medicines (OR = 0.23; 95% CI 0.10 to 0.51). No SJZT-based therapies-related adverse effect was reported.

Conclusion
SJZT-based prescriptions may be effective in treating FD and no serious side-effects were identified, but the effect on response rate appeared to be limited to MSJZT. The results should be interpreted with caution as all the included studies were considered at a high risk of bias. Standardized, large-scale and strictly designed RCTs are needed to further validate the benefits of SJZT-based therapies for FD management.

A standardized polyherbal preparation POL-6 diminishes alcohol withdrawal anxiety by regulating Gabra1, Gabra2, Gabra3, Gabra4, Gabra5 gene expression of GABAA receptor signaling pathway in rats
Authors: Sharma Lalit , Sharma Aditi , Dash Ashutosh Kumar , Bisht Gopal Singh , Gupta Girdhari Lal 
Published: January 2021

Abstract
Background
Alcohol abuse is a major problem worldwide and it affects people’s health and economy. There is a relapse in alcohol intake due to alcohol withdrawal. Alcohol withdrawal anxiety-like behavior is a symptom that appears 6–24 h after the last alcohol ingestion.

Methods
The present study was designed to explore the protective effect of a standardized polyherbal preparation POL-6 in ethanol withdrawal anxiety in Wistar rats. POL-6 was prepared by mixing the dried extracts of six plants Bacopa monnieri, Hypericum perforatum, Centella asiatica, Withania somnifera, Camellia sinesis, and Ocimum sanctum in the proportion 2:1:2:2:1:2 respectively. POL-6 was subjected to phytochemical profiling through LC-MS, HPLC, and HPTLC. The effect of POL-6 on alcohol withdrawal anxiety was tested using a two-bottle choice drinking paradigm model giving animals’ free choice between alcohol and water for 15 days. Alcohol was withdrawn on the 16th day and POL-6 (20, 50, and 100 mg/kg, oral), diazepam (2 mg/kg) treatment was given on the withdrawal days. Behavioral parameters were tested using EPM and LDT. On the 18th day blood was collected from the retro-orbital sinus of the rats and alcohol markers ALT, AST, ALP, and GGT were studied. At end of the study, animals were sacrificed and the brain was isolated for exploring the influences of POL-6 on the mRNA expression of GABAA receptor subunits in the amygdala and hippocampus.

Results
Phytochemical profiling showed that POL-6 contains major phytoconstituents like withaferin A, quercetin, catechin, rutin, caeffic acid, and β-sitosterol. In-vivo studies showed that POL-6 possesses an antianxiety effect in alcohol withdrawal. Gene expression studies on the isolated brain tissues showed that POL-6 normalizes the GABAergic transmission in the amygdala and hippocampus of the rats.

Conclusion
The study concludes that POL-6 may have therapeutic potential for treating ethanol-type dependence.

Published: January 2021

AbstractBackgroundFleas frequently infest small mammals and play important vectoring roles in the epidemiology of (re)emerging zoonotic disease. Rodent outbreaks in intensified agro-ecosystems of North-West Spain have been recently linked to periodic zoonotic diseases spillover to local human populations. Obtaining qualitative and quantitative information about the composition and structure of the whole flea and small mammal host coexisting communities is paramount to understand disease transmission cycles and to elucidate the disease-vectoring role of flea species. The aims of this research were to: (i) characterise and quantify the flea community parasiting a small mammal guild in intensive farmlands in North-West Spain; (ii) determine and evaluate patterns of co-infection and the variables that may influence parasitological parameters.MethodsWe conducted a large-scale survey stratified by season and habitat of fleas parasitizing the small mammal host guild. We report on the prevalence, mean intensity, and mean abundance of flea species parasitizingMicrotus arvalis,Apodemus sylvaticus,Mus spretusandCrocidura russula. We also report on aggregation patterns (variance-to-mean ratio and discrepancy index) and co-infection of hosts by different flea species (Fager index) and used generalized linear mixed models to study flea parameter variation according to season, habitat and host sex.ResultsThree flea species dominated the system:Ctenophthalmus apertus gilcolladoi, Leptopsylla taschenbergiandNosopsyllus fasciatus. Results showed a high aggregation pattern of fleas in all hosts. All host species in the guild sharedC. a. gilcolladoiandN. fasciatus, butL. taschenbergimainly parasitized mice (M. spretusandA. sylvaticus). We found significant male-biased infestation patterns in mice, seasonal variations in flea abundances for all rodent hosts (M. arvalis, M. spretusandA. sylvaticus), and relatively lower infestation values for voles inhabiting alfalfas. Simultaneous co-infections occurred in a third of all hosts, andN. fasciatuswas the most common flea co-infecting small mammal hosts.ConclusionsThe generalistN. fasciatusandC. a. gilcolladoidominated the flea community, and a high percentage of co-infections with both species occurred within the small mammal guild.Nosopsyllus fasciatusmay show higher competence of inter-specific transmission, and future research should unravel its role in the circulation of rodent-borne zoonoses.Graphical Abstract
