Rumour detection on social media through Ensemble deep learning model
Authors: rani neetu
Published: May 2023

The widespread dissemination of several rumours and fake news has extremely affected many business organizations. Rumours or fake news spread and go viral on social websites causing significant social, business and political problem around the world. Fake news distorts public belief, affects companies reputation, disturbs community, reduces government integrity, makes business vulnerable and creates an enormous danger to the social constancy. This paper proposes a novel algorithm to detect rumour spread through tweeter. Various advanced machine learning techniques: Random Forest, Gradient Boosting, Adaboost and Hard Voting classifier are applied to detect the rumours from online social media through tweeter and Facebook. The proposed model is based upon the CNN-BiLSTM-BiGRU approach which efficiently classifies tweets among rumours and non-rumours category. The proposed model provides 99% accuracy and outperforms other baseline models like Random Forest, AdaBoost, Gradient Boosting, and Hard Voting. This hybrid recommender framework can be a more beneficial system to detect rumours at earlier stages from online platforms.

The automated correction of errors in the Handwritten Text Recognition (HTR) output can be challenging and is far from solved. To address this challenge, we set up a shared task on AIcrowd that received 271 submissions, of which very few succeed. This paper presents the datasets, the best methods, and experimental analysis in error-correcting HTRed manuscripts and papyri in Byzantine Greek, the language that followed Classical and preceded Modern Greek. By using recognised and transcribed data from seven centuries, the two best-performing methods are compared, one based on a neural encoded-decoder architecture and the other based on linguistic knowledge. We show that the recognition error rate can be reduced by both, up to 2.5 points at the level of characters and up to 15 at the level of words, also highlighting the weak and strong points of each.
Diversity and evolution of the vertebrate chemoreceptor gene repertoire
Authors: Policarpo Maxime , Baldwin Maude , Casane Didier , Salzburger Walter
Published: May 2023

Chemoreception – the ability to smell and taste – is an essential sensory modality of most animals. The number and type of chemical stimuli that animals can perceive depends primarily on the diversity of chemoreceptors they possess and express. In vertebrates, six families of G protein-coupled receptors form the core of their chemosensory system, the olfactory/pheromone receptor gene families OR, TAAR, V1R and V2R, and the taste receptors T1R and T2R. Here, we provide the most comprehensive study to date of the vertebrate chemoreceptor gene repertoire and its evolutionary history. Through the examination of 2,210 vertebrate genomes, we uncover substantial differences in the number and composition of chemoreceptors across vertebrates. We show that the chemoreceptor gene families are co-evolving, highly dynamic, and characterized by lineage-specific expansions (for example, OR in tetrapods; TAAR, T1R in teleosts; V1R in mammals; V2R, T2R in amphibians) and losses. Overall, amphibians, followed by mammals, are the vertebrate clades with the largest chemoreceptor repertoires. While marine tetrapods feature a convergent reduction of chemoreceptor numbers, the number of OR genes correlates with habitat in mammals and birds and with migratory behavior in birds, and the taste receptor repertoire correlates with diet in mammals and with aquatic environment in fish.

Published: May 2023

INTRODUCTION
The comparative assessment of different types of palatal rugae and lip prints with malocclusion could give us early evidence about the type of developing malocclusion. An early intervention could help achieve better orofacial structure.
AIM
To establish a correlation between different types of malocclusion with palatal rugae patterns and lip print patterns in children aged 6–12 years old.
MATERIALS AND METHOD
A total of 288 co-operative patients were selected and observed for patterns of palatal rugae using the Thomas and Kotze classification. Lip prints were recorded using the lipstick-cellophane technique and visualized using the Suzuki and Tsuchihashi classification. Malocclusion was compared with lip print and palatal rugae patterns.
RESULTS
The wavy type of palatal rugae pattern was predominant in Class I and II, while the curved type was most commonly seen in the Class III permanent molar relationship. The wavy type of palatal rugae pattern was predominant in Class I, and the curved type was seen more in Class II. Type II lip print pattern was observed in Class I, whereas Type IV lip print pattern was predominant in Class II, and Type V lip print pattern in Class III permanent molar relationship. The Type IV lip print pattern was seen in Class II, and Type II in Class I primary canine relationship.
CONCLUSION
No statistically significant correlation was found between dental malocclusion and palatal rugae pattern. A definite interpretation exists that lip print patterns offer many distinct advantages as a screening tool for malocclusion than palatal rugae patterns.

Published: May 2023

The Road traffic crashes particularly in West Hararghe Zone along Metehara- Dengego road segment on main asphalt has not been studied. Hence, in this study road traffic data of three years (2018–2021) were obtained from five (Gumbi Bordode, Mieso, Chiro, Tulo and Doba) towns of traffic police department and West Hararghe Zone transport Authority in Oromia Regional State. The crash severity index developed by the Roads and Traffic Authority of New South Wales was utilized for ranking and prioritizing of hotspot areas based on accident information. The latest instrument, Global Positioning System was used to collect X, Y, Z coordinates of hot spot areas based the Crash Severity Index (CSI) value. The point data obtained using Global Positioning System and crash severity index value were added to road network data using ArcGIS. The results of finding indicates a total of 263 Road traffic crashes were occurred in the five towns from which about 120 fatal occurred on people, 74 injuries and 69 damaged properties. Based on the value of Crash Severity Index and Crash Frequency (CF) of RTCs top nine hot spot areas were identified and ranked which requires high attention to protect road user and property from damage and loss life. Thus, the government and other concerned stakeholders should provide public education, installing road infrastructure, road marking, traffic signs, improving sight distance and awareness creation to reduce threat of fatalities, injuries and property damage due to RTCs along towns in which the main roads passes in West Hararghe Zone.
Loop current fluctuations and quantum critical transport
Authors: Shi Zhengyan Darius , Else Dominic V. , Goldman Hart , Senthil Todadri
Published: May 2023

We study electrical transport at quantum critical points (QCPs)
associated with loop current ordering in a metal, focusing specifically
on models of the “Hertz-Millis” type. At the infrared (IR) fixed point
and in the absence of disorder, the simplest such models have infinite
DC conductivity and zero incoherent conductivity at nonzero frequencies.
However, we find that a particular deformation, involving
NN
species of bosons and fermions with random couplings in flavor space,
admits a finite incoherent, frequency-dependent conductivity at the IR
fixed point, \sigma(\omega>0)\sim\omega^{-2/z}σ(ω>0)∼ω−2/z,
where zz
is the boson dynamical exponent. Leveraging the non-perturbative
structure of quantum anomalies, we develop a powerful calculational
method for transport. The resulting "anomaly-assisted large
NN
expansion" allows us to extract the conductivity systematically.
Although our results imply that such random-flavor models are
problematic as a description of the physical
N = 1N=1
system, they serve to illustrate some general conditions for quantum
critical transport as well as the anomaly-assisted calculational
methods. In addition, we revisit an old
result that irrelevant operators generate a frequency-dependent
conductivity, \sigma(\omega>0) \sim \omega^{-2(z-2)/z}σ(ω>0)∼ω−2(z−2)/z,
in problems of this kind. We show explicitly, within the scope of the
original calculation, that this result does not hold for any order
parameter.
Rice Nutraceuticals and Bioactive Compounds: Extraction, Characterization
and Antioxidant Activity: A Review
Authors: Zubair Muhammad , Anwar Farooq , Arshad Insha , Malik Shanza , Zafar Muhammad Nadeem
Published: May 2023

Rice (Oryza sativa L.), a cereal grass, belongs to the genus Oryza from the family Poaceae,
which encompasses twenty-five species cultured in many countries of Asia, and partly in the
rest of the world. From these species, two viz. Oryza sativa (O. sativa) Asian rice and Oryza glaberrima
(O. glaberrima) African rice are commonly found and the most widely consumed staple
food by a large part of the human population in the world, especially in Asia due to their nutritional
and nutraceutical prospects. Rice, a popular source of carbohydrates, also contains a good amount
of dietary fiber, minerals (Ca, Zn, Se, P, K, Mg, Fe, and Mn), protein and vitamin B along with
several other medicinally important bioactives such as tocols (α-tocopherols and α-tocotrienols) (ßsitosterol)
phenolic acids, flavonoids (apiginine), and oryzanol (24-Methylenecylcoartanyl transferulate).
Rice bran is a byproduct of the rice polishing industry and is valuable in terms of containing
15-20% high-value oil. Because of the natural antioxidants present in rice, several medicinal
benefits and biological properties can be attributed to rice consumption. The nutrient profile of rice
varies based on several factors, such as grains (white, brown, red, and black/purple), the extent of
polishing, and the preparation method. Considering the importance of rice as a traditional diet rich
in high-value bioactives, together with the existing gap of related information, it is worthwhile to
assemble a comprehensive review that focuses on the detailed profile of valuable nutrients and
high-value phytochemicals and biological activities of rice to explore its functional food and
nutraceutical applications. This review attempts to provide collective information on the essential
rice cereal for its nutritional and antioxidant potential.

Skin diseases such as atopic dermatitis affect babies, children, and adults and are characterized
by red skin/spots, severe itching that appears on the face, head, legs, neck, and hands, and various
causes of illness caused by various external and internal factors. AD is a type IIgE-mediated hypersensitivity
reaction. Herbal preparations treat various dermatological diseases like dry skin, melasma, acne,
and eczema. Cosmeceuticals are the connection between cosmetics and medicine, one of the world's
most used forms of medicine. Cosmeceuticals products are beneficial in treating AD. Herbal cosmetics
play a major role in curing various skin diseases. Today, various herbs used in cosmeceuticals have
anti-inflammatory, antioxidant, antibacterial, and antiseptic effects. Compared to synthetic preparations,
herbal preparations have fewer side effects. This review paper introduces Atopic dermatitis, cosmeceutical,
and various phytoconstituents like gallic acid, ferulic acid, boswellic acid, quercetin, and
naringenin tetra hydroxyl flavanol glycoside, glycyrrhizic acid, epigallocatechin gallate, etc., used in

Research Progress on Activity and Biosynthesis of Diketopiperazines
Authors: Liu Bing , Lu Ruiyang , Chen Ning , Yuan Hongliang , Zhao Jintong , Zhao Yuechen
Published: May 2023

Diketopiperazines (DKPs) are mainly produced by microorganisms. In recent years, active
natural products with DKPs structure have been isolated from marine bacteria, actinomycetes and
fungi. The stable six-membered ring framework makes DKPs a vital pharmacophore in medicinal
chemistry. Several recent studies have demonstrated that it has antibacterial, antifungal, antiviral, antitumor,
immunosuppressive, neuroprotective, anti-malaria, anti-prion, and anti-hyperglycemia properties.
Some DKPs are signaling molecules for intercellular communication, which can activate or
inhibit bacterial Lux R-mediated quorum sensing. They are considered potential new anti-infective
drugs that could control biofilm formation by interfering with information communication between
microbes. DKPs possess excellent biological activities and have received extensive attention from
medicinal chemistry workers. Bioactivity studies of DKPs have revealed that many highly active lead
compounds exist in antibacterial, antitumor, and antiviral fields and in treating neurological disorders.
This paper reviews the research progress of diketopiperazines in the past ten years.

Background:

In the last few decades, it has been largely perceived that the factors affecting the immune system and its varying pathways lead to the pathological progression of inflammation and inflammatory conditions. Chronic inflammation also contributes to common diseases, such as diabetes mellitus, ischemic heart disease, cancer, chronic renal inflammatory disease, non-alcoholic fatty hepat-ic disease, autoimmune diseases and neurodegenerative diseases.

Objective:

Interestingly, plant sources and secondary metabolites from plants have been increasingly employed in managing acute and chronic inflammatory diseases for centuries. Boswellic acids are pentacyclic triterpenoidal moieties obtained from the oleo gum resin of different Boswellia species.

Methods:

Detailed data was collected revealing the anti-inflammatory potential of Boswellic acids through various databases.

Results:

These are pharmacologically active agents that possess promising anti-inflammatory, anti-arthritic, antirheumatic, anti-diarrheal, anti-hyperlipidemic, anti-asthmatic, anti-cancer, and anti-microbial effects.

Conclusion:

Boswellic acids have been in use since ancient times primarily to treat acute and chronic inflammatory diseases. This review discusses the various mechanisms underlying the inflammatory process and the necessity of such natural products as a medication to treat inflammatory diseases. In addition, a discussion has also been extended to understand the primary targets involved in inflamma-tion. The review further explores the therapeutic potential of boswellic acids in

Spin fluctuation spectroscopy (SNS) is a conceptually new version of magnetic resonance spectroscopy, experimentally demonstrated in 1981 and strongly developed in the last two decades. Atomic systems and semiconductors served as main objects of the SNS. It became possible to apply SNS to crystals with rare-earth impurities - classical objects of EPR spectroscopy and the subject of constant interest of P.P. Feofilov, only in recent years, due to specific combination of spectroscopic properties of rare-earth ions with characteristics of the stochastic signal formation in SNS. In this article, we consider the specific characteristics of application of SNS to crystals with rare-earth ions and briefly describe the results of experimental studies, which made it possible to significantly expand the scope of possibilities of this method.

Authors: Mayasari Iin , Haryanto Handrix Chris , Hutagaol Olivia Deliani , Ramadhan Adam Rizky , Amir Iwan
Published: May 2023

Purpose: Local fashion brands are an important issue for millennial consumers. To create their love of local fashion brands, social media marketing is necessary.  The study also examines brand love's effects on local fashion brands' centrality. This study also investigates brand love and centrality’s impact on the repurchase intention. Design/ Methodology/Approach: The data were taken using survey methods with questionnaires developed by previous researchers. A partial least squares regression was used to test the hypotheses. Findings: This study shows that social media marketing can create conditions for consumers to develop brand love, but brand love still needs to be able to develop brand centrality. This study also shows that although brand love has yet to create brand centrality, the concept of brand love can influence the repurchase intention. At the same time, brand centrality also affects the repurchase intention. Originality/value: This is the first study analyzing millennials’ brand love toward fashion clothing brands and the analysis of the influence of social media marketing on brand love and its impact on brand centrality.

Abstract: The application of clustering algorithms in tourism data analysis has become an important research area in recent years. The objective of this study is to provide an overview of the different clustering algorithms used in tourism data analysis and their applications. Clustering algorithms are used to group data into clusters based on similarities and differences between the data points. In tourism, clustering algorithms are used to identify different segments of tourists based on their preferences, behaviors, and characteristics. These segments can be used to target specific marketing strategies and improve tourism experiences. The study presents a comprehensive review of the different clustering algorithms, including hierarchical clustering, k-means clustering, density-based clustering, and model-based clustering. The advantages and disadvantages of each algorithm are discussed in detail. In addition, the study highlights the different applications of clustering algorithms in tourism data analysis, such as destination profiling, market segmentation, customer behavior analysis, and recommendation systems. Overall, the study shows that clustering algorithms have a significant impact on tourism data analysis and decision-making processes. They provide valuable insights into the behavior and preferences of tourists, which can be used to improve tourism products and services. However, the selection of the appropriate clustering algorithm depends on the nature of the data and the research objectives.

Periodic nonuniform sinc-Gauss sampling
Authors: Asharabi Rashad
Published: May 2023

The periodic nonuniform sampling has attracted considerable attention both in mathematics and engineering although its convergence rate is slow. To improve the convergence rate, some authors incorporated a regularized multiplier into the truncated series. Recently, the authors of [18] have incorporated a Gaussian multiplier into the classical truncated series. This formula is valid for bandlimited functions and the error bound decays exponentially, i.e. ? Ne??N, where ? is a positive number. The bound was established based on Fourier-analytic approach, so the condition that f belongs to L2(R) cannot be considerably relaxed. In this paper, we modify this formula based on localization truncated and with the help of complex-analytic approach. This formula is extended for wider classes of functions, the class of entire functions includes unbounded functions on R and the class of analytic functions in an infinite horizontal strip. The convergence rate is slightly better, of order e??N/? N. Some numerical experiments are presented to confirm the theoretical analysis.

Investigating inhibition characteristics of Butea monosperma leaf extracts to retard stainless steel biocorrosion in the presence of sulfate-reducing bacteria
Authors: Manu Shiv , Selvam Noyel , Ramachandran Manivannan
Published: May 2023

The influence of sulfate-reducing bacteria Desulfovibrio desulfuricans on stainless steel SS 202 corrosion in neutral media was studied in detail using weight loss and electrochemical routes. The bacterial activity resulted in material loss with an average rate of 0.015 mm/year. The scanning electron microscopy (SEM) analysis showed a significant increase in the sessile bacterial population with the immersion period. Use of 500 ppm palash (Butea monosperma) leaf extract (PLE) reduced the average corrosion rate to 0.002 mm/year. SEM analysis showed a very thin external film formation in the presence of the inhibitor. The X-ray photoelectron spectroscopy studies confirmed the presence of corrosion products such as Fe2O3 and FeS. The gas chromatography?mass spectrometry studies showed the dominant percentage of various terpenoids along with vitamin E as the main components of the PLE. Electrochemical analysis showed the existence of a diffusion barrier. The resistance offered by the diffusion barrier is high in the inhibited sample when compared to uninhibited samples.

Dewasa ini, pemerataan infrastruktur menjadi pusat perhatian bagi pemerintah. Pemerintah saat ini tengah gencar mensosialisasikan pembangunan infrastruktur Indonesia sentris. Pembangunan yang bersifat menyeluruh dan menyentuh setiap pelosok negeri. Pembangunan yang diharapkan dapat membuka potensi lokal menuju kemandirian daerah sekaligus turut mendukung kemajuan perekonomian nasional. Daerah Sumatera Selatan juga menjadi salah satu sasaran pembangunan infrastruktur. Jalan Tol Trans Sumatera adalah jaringan jalan tol sepanjang 2.818km di Indonesia yang direncanakan menghubungkan kota-kota di pulau Sumatera, dari Lampung hingga Aceh. Pembangunan jalan bebas hambatan kemudian berlanjut pada pembangunan proyek Jalan Tol Ruas Kayu Agung-Palembang Betung Paket I seksi 1A. Ruas Jalan Tol Ruas Kayu Agung-Palembang Betung Paket I seksi 1A memiliki panjang ±13,4km. Kondisi area proyek tol Kayu Agung – Palembang– Betung yang merupakan mayoritas adalah rawa yang menjadikan infrastruktur jalan dibangun pada tanah area lunak, sehingga masalah penurunan berlebihan menjadi faktor yang penting dan harus dicari solusinya. Pada lokasi tanah yang bersifat lunak, sebelum dilakukan pembangunan infrastruktur umumnya perbaikan tanah harus dilakukan lebih dulu guna menjamin stabilitas jangka pendek maupun jangka panjangnya. Seperti halnya pada bangunan infrstruktur jalan area proyek tol Kayu Agung – Palembang– Betung untuk rentang penanganan awal antara Sta 5+000- 5+360. Di antara rentang tersebut, hasil sondir yang dilakukan terdapat tanah lunak dengan kedalaman yang bervariasi. Dengan adanya kedalaman tanah lunak tersebut, maka penurunan yang terjadi cukup besar. Untuk menangani penurunan yang terjadi tersebut, salah satu solusinya dengan mempercepat penurunan konsolidasi. Percepatan konsolidasi yang dimaksud adalah dengan menambahkan material Prefabricated Vertical Drain (PVD). Vertical drain ini sendiri dibedakan menjadi dua metode, yaitu metode PVD Preload dan metode PVD Vacuum. Penurunan yang terjadi terhadap tanah dasar akan menyebabkan pemampatan serta kuat geser akan meningkat, sehingga kapasitas daya dukung tanah dasar juga akan meningkat.
