Authors: Lima Douglas Mateus , Júnior Humberto Correia Lima , Medeiros Iálysson Silva
Published: January 2023

Same Bamboos species have mechanical properties compatible with construction material. Despite this, their low shear strength, the presence of nodes in their culms and their circular geometry inhibit the expansion of the use of this material as construction material. One technique that can solve this problem is Glued Laminated Bamboo (GLB). Based on these findings, this paper aims to evaluate the physical and mechanical properties of Glued Laminated Bamboo of the species Dendrocalamus giganteus. Two glues were analyzed: resorcinol-formaldehyde (CASCOPHEN, commercial name) and polyvinyl acetate (CASCOREZ, commercial name). The following physical and mechanical characterization tests were performed on Glued Laminated Bamboo: water absorption, density, compression parallel to the fiber, tension parallel to the fiber, shear parallel to the glue layer, shear parallel to the bamboo fibers and bending. The results, analyzed using statistical models, showed that the Glued Laminated Bamboo has physical and mechanical properties comparable to those of hardwoods.

Background:
To assess the potential clinical utility of cell-free DNA (cfDNA)-based biomarkers for identifying gastric cancer (GC) patients who benefit from nivolumab.
Methods:
From 31 GC patients treated with nivolumab monotherapy (240mg/body, Bi-weekly) in 3rd or later line setting, we prospectively collected blood samples at baseline and before the 3rd dose. We compared cfDNA-based molecular findings, including microsatellite instability (MSI) status, to tissue-based biomarkers. We assessed the clinical value of blood tumor mutation burden (bTMB) and copy number alterations (CNA) as well as the cfDNA dynamics.
Results:
The concordance between deficient-MMR and cfDNA-based MSI-high was 100% (3/3). Patients with bTMB≥6 mut/Mb had significantly better progression-free survival (PFS) and overall survival (OS); however, such significance disappeared when excluding MSI-High cases. The combination of bTMB and CNA positivity identified patients with survival benefit regardless of MSI status (both PFS and OS, P<0.001), with the best survival in those with bTMB≥6mut/Mb and CNAnegative. Moreover, patients with decreased bTMB during treatment had a better disease control rate (P=0.04) and longer PFS (P=0.04).
Conclusions:
Our results suggest that a combination of bTMB and CNA may predict nivolumab efficacy for GC patients regardless of MSI status. bTMB dynamics have a potential utility as an on-treatment biomarker.

Published: January 2023

Amyotrophic lateral sclerosis (ALS) is a severe neurodegenerative disease with selective degeneration of motor neurons. It has been reported that an increase in the levels of inflammatory cytokines and glial cells such as reactive astrocytes is closely involved in the pathological progression of ALS. Recently, the levels of neuropathic cytotoxic (A1) astrocytes among reactive astrocytes have reportedly increased in the central nervous system of ALS mice, which induce motor neuron degeneration through the production of inflammatory cytokines and secretion of neuropathic factors. Hence, elucidating the induction mechanism of A1 astrocytes in ALS is important to understand the mechanism of disease progression in ALS. In this study, we observed that the expression of peroxiredoxin 6 (PRDX6), a member of the peroxiredoxin family, was markedly upregulated in astrocytes of the lumbar spinal cord of SOD1G93A mice model for ALS. Additionally, when PRDX6 was transiently transfected into the mouse astrocyte cell line C8-D1A and human astrocytoma cell line U-251 MG, the mRNA expression of complement C3 (a marker for A1 astrocyte phenotype) and inflammatory cytokines was increased. Furthermore, the mRNA expression of C3 and inflammatory cytokine was increased in C8-D1A and U-251 MG cells stably expressing PRDX6, and the increased mRNA expression was significantly suppressed by MJ33 (lithium[1-hexadecoxy-3-(2,2,2-trifluoroethoxy) propan-2-yl] methyl phosphate), an inhibitor of the phospholipase A2 activity of PRDX6. Our results suggest that the expression of PRDX6 in astrocytes plays an important role in the induction of A1 astrocytes and expression of inflammatory cytokines in the ALS mice model.
Inference in conditioned dynamics through causality restoration
Authors: Braunstein Alfredo , Catania Giovanni , Dall'Asta Luca , Mariani Matteo , Muntoni Anna Paola
Published: January 2023

Estimating observables from conditioned dynamics is typically computationally hard. While obtaining independent samples efficiently from unconditioned dynamics is usually feasible, most of them do not satisfy the imposed conditions and must be discarded.On the other hand, conditioning breaks the causal properties of the dynamics, which ultimately renders the sampling of the conditioned dynamics non-trivial and inefficient. In this work, a Causal Variational Approach is proposed, as an approximate method to generate independent samples from a conditioned distribution. The procedure relies on learning the parameters of a generalized dynamical model that optimally describes the conditioned distribution in a variational sense. The outcome is an effective and unconditioned dynamical model from which one can trivially obtain independent samples, effectively restoring the causality of the conditioned dynamics. The consequences are twofold: the method allows one to efficiently compute observables from the conditioned dynamics by averaging over independent samples; moreover, it provides an effective unconditioned distribution that is easy to interpret. This approximation can be applied virtually to any dynamics. The application of the method to epidemic inference is discussed in detail. The results of direct comparison with state-of-the-art inference methods, including the soft-margin approach and mean-field methods, are promising.
A Study of Abraham’s Effective Hydrogen Bond Acidity and Polarity/Polarizability Parameters, A and S, using Computationally Derived Molecular Properties
Authors: Waghorne Earle
Published: January 2023

Abraham’s hydrogen bond donor and polarity/polarizability parameters, A and S, respectively, are correlated with molecular properties derived from computational chemistry.
The analyses show that A, like Kamlet and Taaft’s α, correlates only with the charge on the most positive hydrogen atom of the molecule but that there are marked steric effects.
In contrast, S correlates with the molecular dipole moment, the partial charge on the most negative atom in the molecule and with the polarizability of single ring aromatic compounds but not those of aliphatic compounds.
These results are compared with those for corresponding Kamlet and Taft parameters, α and π* and Reichardt’s ET(30) and discussed in terms of the experimental methods used to determine the parameters.
Engagement over telehealth: Comparing attendance and drop-out between Dialectical Behaviour Therapy delivered face-to-face and via telehealth for programs in Australia and New Zealand during the Covid-19 pandemic
Authors: Walton Carla , Gonzalez Sharleen , Cooney Emily B. , Leigh Lucy , Szwec Stuart
Published: January 2023

Background
While the COVID-19 crisis has had numerous global negative impacts, it has also presented an imperative for mental health care systems to make digital mental health interventions a part of routine care. Accordingly, through necessity, many Dialectical Behaviour Therapy (DBT) programs transitioned to telehealth, despite little information on clinical outcomes compared with face-to-face treatment delivery. This study examined differences in client engagement (i.e. attendance and drop-out rates) of DBT: delivered face-to-face prior to the first COVID-19 lockdown in Australia and New Zealand; delivered via telehealth during the lockdown; and delivered post-lockdown. Our primary outcomes were to compare: (1) client attendance rates of DBT individual therapy delivered face-to-face with delivery via telehealth, and (2) client attendance rates of DBT skills training delivered face-to-face compared with delivery via telehealth.
Methods
DBT programs across Australia and New Zealand provided de-identified data for a total of 143 individuals who received DBT treatment provided via telehealth and face-to-face over a six-month period in 2020. Data included attendance rates of DBT individual therapy sessions; attendance rates of DBT skills training sessions as well as drop-out rates and First Nations status of clients.
Results
A mixed effects logistic regression model revealed no significant differences between attendance rates for clients attending face-to-face sessions or telehealth sessions for either group therapy or individual therapy. This result was found for clients who identified as First Nations persons and those who didn’t identify as First Nations persons.
Conclusions
Clients were as likely to attend their DBT sessions over telehealth as they were face-to-face during the first year of the Covid-19 pandemic. These findings provide preliminary evidence that providing DBT over telehealth may be a viable option to increase access for clients, particularly in areas where face-to-face treatment is not available. Further, based on the data collected in this study, we can be less concerned that offering telehealth treatment will compromise attendance rates compared to face-to-face treatment. Further research is needed comparing clinical outcomes between treatments delivered face-to-face compared delivery via telehealth.

Authors: Syed Murtaza Hussain , Syed Ali Hassan
Published: January 2023

Face recognition is becoming a popular field in the evolution of computer applications in the last several years due to the vast range of software. Face identification is arduous because of the enormous variety of faces. Facial recognition is related to image processing, pattern recognition, and computer vision. The development of face recognition algorithms necessitates constantly creating new methods to face authentication technology. A review of human face recognition is mentioned in this paper. The Application and Principles of face recognition are discussed along with the face databases used to determine the efficiency of these face recognition algorithms and their flaws. Two basic techniques for feature extractions are analyzed to identify a face. Model-based methods, appearance-based and hybrid systems are described. The features of suitable face identification, distance measurements, face databases, classification, and an overview of necessary person recognition studies are also discussed with the implementation of the own created dataset. Finally, proposed techniques and challenges with future trends are highlighted.

Published: January 2023

The application of radiology as an aid for paleoanthropological analyses is seeing a widespread increase. The aim of this study is to examine a number of radiological dental aspects related to hereditary haemoglobinopathies, such as b-thalassemia, on the human remains of a past community by way of micro-CT. A sample from the early medieval (10th-11th century) archaeological site of Vetricella (Scarlino, Grosseto), located in an area historically affected by malaria and part of the nEU-Med Advanced ERC project, was selected. Macroscopic paleopathological analysis revealed features typical of b-thalassemia. As a result, the skeletal remains underwent CT and micro-CT examination. CT analysis of the ribs, as demonstrated in previous studies, confirmed the initial hypothesis of the presence of b-thalassemia in the group. The dental micro-CT carried out on a sample of 7 deciduous incisors belonging to 7 sub-adult individuals allowed observing for the first time a direct relationship between the degrees of b-thalassemia recorded on the skeletons and dentinogenesis defects, identifying also a new radiological evidence which will be termed as «iris-like» appearance. A sample of three individuals from a coeval, non-thalassemic community was used for comparative purposes. These observations constitute a new approach to the diagnosis of b-thalassemia in archaeological contexts, providing an additional tool for differential diagnoses while also furthering our knowledge of the natural history of this disease.

Authors: Hong Liang , Liu Feng , Zhan Rulin , Hu Jianfang
Published: January 2023

Mangos are an important tropical fruit with an abundance of species resources. SSR molecular markers have been widely used to identify and distinguish the genetic relationship of mango cultivars. The statistical results of SSR loci information in mango simplified genome sequencing show the number of dinucleotide repeat elements to be the largest, which accounts for 40% of the total SSR loci. The repetition times for each nucleotide element were mainly six. The nucleotide types of AT/AT and A/T are 17.8% and 21.2%, respectively, which accounts for 39% of total SSR. The length of SSR loci concentrated in 15bp, with 2,931 loci, which accounts for 20.12%. At the same time, the genetic diversity and phylogenetic relationship of 71 mango cultivars are analyzed. The MISA is used for searching SSR loci, designing and screening SSR primers with good polymorphism, and 20 pairs of primers are chosen following the screening of 200 pairs of primers by gel electrophoresis. The genetic diversity of mango germplasm from two different distribution areas is analyzed, and the genetic similarity coefficients are clustered by unweighted group average method (UPGMA). Genetic distance cluster analysis shows that 71 mango germplasm are divided into seven categories when the genetic similarity coefficient is 0.89, and the similarity coefficient range is 0.55 to 1, polymorphism information content (PIC) values ranging from 0.2334 to 0.7997. In summary, our findings could be used for genetic diversity analysis and the marker-assisted breeding of mango germplasm.

Authors: Chib S. , Dalil-Essakali L. , Belafhal A.
Published: January 2023

In this paper, we introduce a global power spectrum model to describe the fluctuations of the refractive index both in turbulent biological tissue and in a turbulent marine environment. Based on the extended Huygens-Fresnel diffraction integral, the propagation of partially coherent Generalized Flattened Hermite Cosh-Gaussian (GFHChG) beam in turbulent biological tissue is investigated using the proposed power spectrum. Numerical examples are illustrated with various source parameters to describe the evolution of the laser beam in biological tissue. The GFHChG beam exhibits different beam profiles upon propagation in turbulent biological tissue, reaching a Gaussian shape, as the incident beam parameters are smaller. A comparison of the beam comportment in two biological tissues is also given. The obtained results can be useful for the development of technologies used in the biological tissue.

Published: January 2023

Cu2AlSnS4 (CATS) was generated through directly fusing of extremely pure elements. Powder show a tetragonal crystal system belongs to the space group Fd3m and the CATS film displays narrow and weak diffraction peaks corresponding to the CZTS structure of pure kesterite without secondary phase. The surface appearance and chemical content films exposed their homogenous character. The optical analysis displayed good visible-range optical absorption and optical direct band gap of 1.30–1.65 eV with excellent transmission. CATS showed high photocatalytic efficacy to degrade methylene blue (MB) completely under UV-light irradiation. These results will open the opportunity for using this new material as talented candidate in solar cells and removing organic pollutants from aqueous solutions.

Published: January 2023

Purpose
Lower gastrointestinal bleeding (LGIB) can be fatal; therefore, several scoring systems have been developed to predict its prognosis. We aimed to compare the mortality predictions and evaluate the usefulness of various scoring systems.
Methods
The medical records of 3,794 patients who visited the emergency department with hematochezia between January 2016 and December 2021 were retrospectively reviewed. We calculated the areas under the receiver operating characteristic curves (AUROCs) for 30-day mortality and prolonged hospital stay (≥ 10 days), based on the age, blood tests, and comorbidities (ABC); AIMS65; Glasgow Blatchford; Oakland; Rockall (pre-endoscopy); and SHA2PE scores. We compared the predictive accuracy of each score.
Results
Data for 963 patients (median age, 69 years; males, 54.5%; median hospital stay, 6 days) with colonoscopy-confirmed LGIB were analyzed. The 30-day mortality rate was 3.5%. The most common causes of LGIB were ischemic colitis and diverticulum hemorrhage in 19.3% and 19.2% of the cases, respectively. The AIMS65 (AUROC, 0.845) and ABC (AUROC, 0.835) scores were superior in predicting 30-day mortality (both p < 0.001). The SHA2PE score was the most accurate predictor of prolonged hospital stay (AUROC, 0.728; p < 0.001). Through multivariate regression analysis, 30-day mortality was correlated with albumin level ≤ 3.0 g/dL, international normalized ratio > 1.5, blood urea nitrogen level ≥ 30 mg/dL, and systolic blood pressure (SBP) < 100 mmHg. Prolonged hospital stay was correlated with liver cirrhosis, hemoglobin ≤ 10 g/dL, albumin level ≤ 3.0 g/dL, and SBP < 100 mmHg.
Conclusion
The recently developed scoring systems accurately predict LGIB prognosis, and their usefulness in clinical decision-making was confirmed.
Thermal conductivity calculation model for refrigerant mixtures in the vapor phase
Authors: Raschektaeva E. P. , Stankus S. V.
Published: January 2023

Thermal conductivity measurements of ten refrigerant mixtures (R-404A, R-406A, R-407C, R-409A, R-410A, R-415A, R-507A, R-227ea/R-134a 61.5/38.5, R-227ea/R-134a 88.8/11.2, R-227ea/R-134a 45/55) in the gas phase are analysed. The thermal conductivity was studied with the same experimental setup, which improved the reliability of the results, excluding thereby systematic errors caused by using different methods to measure thermal conductivity. The reported experimental data have 1.5–2.5 % uncertainty. Equations for calculating thermal conductivity depending on temperature and pressure are given for each mixture. The equations for thermal conductivity on the dew line and in the ideal gas state are obtained. A model for predicting thermal conductivity on a wide range of state parameters is proposed based on obtained experimental data and the theory of thermodynamic similarity. A comparison of the experimental data with the calculation model gives the standard deviation at 0.4–2.1 %, which does not exceed the measurement error.
Stabilizing the Propagation of the Weighted Finite-Difference LSRTM Riemannian Wavefield Extrapolator
Authors: Muhammed Hussein
Published: January 2023

Earth’s subsurface illuminating is a great problem of interest. Least-squares reverse-time migration is considered as a cutting-edge technique due to its advance structural irradiating which can be seen from the corresponding mathematics and optimization. Its procedure consumes a lot of time and occupies huge memory amounts thus wavefield extrapolation has been juxtaposed in a Riemannian coordinate system to transform the vertical axis to overcome the above-mentioned issues and oversampling/aliasing for modelling deeper parts of the seismic section. The problem of stabilizing this Riemannian wavefield arises from the introduction of the mapping velocity and the vertical axis operator that converts the finite difference solution partially from time into frequency domains. For every point in the Cartesian space, there is a corresponding vertical-time point with the coordinates hence we can interpolate the reconstructed source wavefield by drawing a Cartesian-to-Riemannian mapping function. Our stability and convergence analysis suggests that the spatial derivatives of Riemannian axis can be approximated by a Fourier pseudo-spectral methods as well as fast-Fourier transform using a special Gaussian-like impulse function to generate the vector-matrix of the source term within the finite-difference operator, in addition to the mapping velocity, which is a differential form of the initial input velocity model, manifestly controls the CFL conditions of the associated Riemannian-finite difference operator. Numerical and synthetic examples indicate that this approach is more stable and efficient in extrapolating a smooth Riemannian wavefield while maintaining Claerbout’s principle for locating subsurface reflectors also choosing an appropriate sampling rate for the new vertical axis is related inversely by the maximum frequency of the impulse wavelet and directly with minimum velocity value in the given model.
Analysis, Attribution, and Authentication of Drawings with Convolutional Neural Networks
Authors: Frank Steven J. , Frank Andrea M.
Published: January 2023

We propose an innovative framework for assessing the probability that a subject drawing is the work of a particular artist. While numerous efforts have applied neural networks to classify two-dimensional works of art by style and author, these efforts — with few exceptions — have been limited to paintings. Drawings, which can involve multiple media with very different visual characteristics and greater susceptibility to damage than paint, present a more formidable challenge. Our technique is robust to the age and wear of a drawing as well as the possibility that it contains marks made with multiple drawing media. We obtained classification accuracies exceeding 90% using a five-layer convolutional neural network (CNN), which we trained on a curated set of drawing images attributed to Raffaello Sanzio da Urbino (1483–1520), known as Raphael, as well as drawings by his admirers, imitators, and forgers.

Authors: Fu Jiantao , Ma Zewen , Wang Lanying , Zhang Yunfei , Luo Yanping
Published: January 2023

The red imported fire ant (RIFA), Solenopsis Invicta Buren (Hymenoptera: Formicidae), is an invasive species that is considered to be among the 100 most dangerous species to human health and the environment. RIFA is currently controlled primarily by chemical pesticides. Human health concerns and environmental problems require environmentally friendly, green control technology. In this study, the HS-SPME–GC/MS method was used to determine the volatile components of six essential oils, namely I. verum, B. balsamifera, C. lemon, A. tatarinowii, M. chinensis and C. cassia, as well as the fumigation activity of RIFA. There was an identification of D-Limonene as a core volatile. Except for C. limon essential oil, all other five plant essential oils exhibit excellent fumigation activity under the treatment of a high dose (10 µL) within 24 h. All plant essential oils are capable of causing the death of all red fire ants, while C. limon essential oil exhibits the lowest fumigation activity at 63.25%. Significant reductions in RIFA aggregation, aggressiveness, and gripping abilities were observed with all plant essential oils, and antenna sensilla appeared to bend or break. Moreover, after treating red ant fire ants with essential oil for 24 h, three protective enzymes were assessed. All six plant essential oils were shown to have enhanced enzyme activities for superoxide dismutase (SOD), glutathione S-transferase (GST), and catalase (CAT). It has been shown that plant essential oils have the capability of reducing the viability of red fire ants via physiological, receptor, and behavioral factors, ultimately causing them to die off. In this study, plant oils were demonstrated to be negatively affecting RIFA and providing a green and environmentally sustainable control method.
Three-non Quantum Communication
Authors: Xu Qifeng
Published: January 2023

In the 40 years since the BB84 protocol was proposed, the practical progress of quantum communication has been relatively slow, because many key technologies have not yet made breakthroughs. This paper proposes a model that can be supported by existing technologies, that is, three-non quantum communication which has no quantum key distribution, no teleportation, and no information transmission. Its working principle is that Alice uses fiber channel or free space to send polarized entangled photon streams to Bob and has the controllable decoherence of entangled photons with the industrial-grade optoelectronic devices, and her control role is equivalent to information coding to realize communication functions. It also has other characteristics such as no requirement for code rate, single-photon detection, quantum base operations and classical channel, etc. It has a low requirement for light sources and transmission channels and is easy to implement.

Authors: Zhang Song , Zhang Song , Ma Zhaolei
Published: January 2023

Objective
To compare the prognostic effects of two different anesthesia methods on endovascular treatment (EVT) of acute anterior circulation ischemic stroke.
Methods
We collected 90 cases of patients with acute anterior circulation ischemic stroke who received endovascular treatment, and these patients were randomly divided into general anesthesia (GA) group and conscious sedation (CS) group before operation. We recorded the related parameters of EVT under the two anesthesia methods for comparative study. The main outcome index of this study was a good neurological prognosis after 90 days of EVT.
Results
In this study, a total of 174 patients with acute ischemic stroke were screened, 90 cases met the inclusion criteria. The 90 cases were randomly divided into GA group and CS group before receiving EVT. Of the 90 cases, 88 cases achieved different degrees of vascular recanalization, and all cases were followed up. There was no significant difference in baseline data, mortality, vascular recanalization, incidence of pneumonia, hospitalization time in ICU, postoperative intracranial hemorrhage, improvement of MRS and NIHSS scores between patients in the two groups. Arterial dissection occurred in 6 cases in CS group and 1 case in GA group, with significant difference. The mean arterial pressure at 10, 20, 30, 60min after anesthesia were different. The time of arterial puncture was different in the two groups, but there was no difference in the time of vascular recanalization. There was no significant difference in neurological function prognosis between patients in the two groups at 90 days. However, there are differences in terms of lung infection, mortality and ICU hospitalization time of elderly patients between the two groups.
Conclusion
There was no significant difference in neurological prognosis between the two anesthesia methods for 90 days after endovascular treatment of acute anterior circulation ischemic stroke. Conscious sedation was superior to general anesthesia for elderly patients.

Published: January 2023

Exploring the effect of tuck loops on fabric properties of some knitted structures was aimed in this study. Samples were produced on a Stoll V-bed knitting loom with 100% acrylic yarn. Five types of knit structures (1x1 rib, half cardigan, double half cardigan, cardigan and double cardigan) were knitted with identical machine settings. Test results revealed that double cardigan fabric has the highest fabric thickness, thermal resistance and coefficient of friction. Double half cardigan provides the highest air permeability, whereas 1x1 rib structure has the highest relative water vapor permeability, mass per unit area and loop length. Half cardigan has the highest bending rigidity. Half cardigan and double half cardigan both have the best pilling results. It was observed that test results of half cardigan-double half cardigan and cardigan-double cardigan are generally similar as pairs. However, dimensional, mechanical and comfort characteristics of 1x1 rib fabric seem quite different.

Authors: Amin Sausan Nafis
Published: January 2023

This study aims to identify students' motivation in learning English through the Duolingo application, its effects, and what makes it different from conventional learning. The Duolingo application is free language acquisition and education for the world. The term acquisition itself is interpreted differently by language researchers. Some researchers distinguish between obtaining and learning. On the other hand, other researchers consider the term to be the same. In this study, researchers refer to the idea that they are the same. In conducting this research, researchers used case studies to analyze data. The researchers were selected five students of second-grade SMK Ngunut 1 Tulungagung who play of Duolingo application to get their second language motivation. Data was collected by direct observation and in-depth interviews with subjects who had two learning language experiences such as books and learning applications. The reason why choosing games as a factor in improving English learning in this study is because games have become one of the results of the development of popular technology in the community.

Published: January 2023

Yppk Assisi Sentani High School is one of the senior high schools located in Sentani City, Jayapura Regency. The registration system used for prospective newstudents is still manual until now. Where when registering, prospective new students are still required to come to the school directly. On the other hand, Jayapura district already has an internet connection that is quite good for accessing websites, especially in the city of Sentani, where Yppk Assisi Sentani High School is located. Based on the problems encountered, I as the author tried to help the process of accepting new students by creating a registration dashboard interface for SMA Yppk Assisi Sentani using the User Centered Design (UCD) method. In addition, testing will be carried out using the Usability Testing and System Usability Scale (SUS) methods. The satisfaction test that has been carried out on users using SUS shows an average percentage of 80 for admins andteachers while for students the average obtained is 73. Therefore, it can be concluded that the registration dashboard of Yppk Assisi Sentani High School is well received. The registration dashboard interface for SMA Yppk Assisi Sentani is expected to be useful for prospective students who will register, because newprospective students can register from anywhere without having to come to school so that it will save time and be more efficient.

Published: January 2023

The statistical combination of disjoint signal regions in
reinterpretation studies uses more of the data of an analysis and gives
more robust results than the single signal region approach. We present
the implementation and usage of signal region combination in MadAnalysis
5 through two methods: an interface to the Pyhf package making use of
statistical models in JSON-serialised format provided by the ATLAS
collaboration, and a simplified likelihood calculation making use of
covariance matrices provided by the CMS collaboration. The gain in
physics reach is demonstrated 1.) by comparison with official mass
limits for 4 ATLAS and 5 CMS analyses from the Public Analysis Database
of MadAnalysis 5 for which signal region combination is currently
available, and 2.) by a case study for an MSSM scenario in which both
stops and sbottoms can be produced and have a variety of decays into

To comprehensively consider and study the seismic performance of the self-center mortise-tenon segmental pier, its vulnerability under earthquake is evaluated. The reliability of the model is verified by comparing the cyclic pseudo-static test results with the finite element models. The model is used as the basis for vulnerability analysis. Taking the maximum displacement of the pier top as a damage index. Different damage states are described. The damage index limits μcy1, μcy, μc2, and μcmax of different damage levels are determined. The time history analysis of cast-in-place pier and mortise-tenon segmental piers under different earthquake actions is carried out by using finite element software. The probabilistic seismic demand model is established through IDA curves. And the seismic vulnerability analysis is carried out. The influence of various parameters on the seismic vulnerability of mortise-tenon segmental pier is studied by changing the longitudinal reinforcement ratio, axial compression ratio, and aspect ratio. The results show that the seismic vulnerability of the two types of piers designed according to the principle of equivalence is similar under different damage states. It can be considered that it has better seismic performance. The longitudinal reinforcement ratio, axial compression ratio, and aspect ratio have a great impact on the vulnerability of piers.
Dynamic analysis of gear pairs with the effects of stick-slip
Authors: Xun Chao , Dai He , Wang Yunlong
Published: January 2023

The instantaneous dynamic contact state analysis is carried out to reveal the process of scuffing failure of the gear tooth pair. A stick-slip dynamic model of a two-gear set is proposed and the coupling effects of time-varying mesh stiffness, tooth separations, friction between the gear teeth surfaces, and potential stick-slip are considered. Dynamic analysis shows that stick contact is an important source of tooth scuffing failure. Additionally, stick contact dramatically increases the vibration amplitudes and causes chaos. Parametric studies show that heavy load and rough tooth surfaces increase the probability of sticking and increase the time of stick state over a single mesh period. This study provides a design guard for avoiding scuffing failure and improving the reliability of gear transmission.

The olive (Olea europaea L.) is one of the most important plants grown in many Mediterranean countries that has a high economic value. Olives, which are specific to each region, have different bioactive components. In this study, we investigated the phenolic/flavonoid contents, as well as antioxidant, antimicrobial, and antithrombotic activities of the fruit, leaf, and seed extracts obtained from the Halhalı olive grown in Arsuz district of Hatay, Turkey.

Antioxidant activities of the phenolic compounds found in the olive fruit, seed, and leaf extracts were determined by employing established in vitro systems. Total phenolics were determined as gallic acid equivalents, while total flavonoids were determined as quercetin equivalents. Also, we evaluated a possible interaction between oleuropein and aggregation-related glycoproteins of the platelet surface via docking studies.

The extracts showed effective antioxidant activity. The seed extract had the highest phenolic content of 317.24 μg GAE, while the fruit extract had the highest flavonoid content of 4.43 μg. The highest potential for metal chelating activity was found in the leaf extract, with an IC50 value of 13.33 mg/mL. Also, the leaf extract showed higher levels of antioxidant, antithrombotic, and antimicrobial activity, compared to the fruit and seed extracts. The docking scores of oleuropein against the target molecules GPVI, α2β1, and GPIbα were calculated as –3.798, –4.315, and –6.464 kcal/mol, respectively.

The olive fruit, leaf, and seed extracts used as experimental material in our study have remarkable antioxidant, antimicrobial, and antithrombotic potential.

Kashk is a perishable fermented dairy product. Since chemical preservatives are harmful for human health, we aimed to study lemongrass (Cymbopogon citratus L.) as a natural preservative.

First, we assessed the phytochemical properties of lemongrass extract. Then, we added lemongrass extract and microencapsulated lemongrass extract to kashk samples. Finally, we analyzed their physicochemical and sensorial properties during 60 days of storage.

Catechin (419.04 ± 0.07 mg/L), gallic acid (319.67 ± 0.03 mg/L), and chloregenic acid (4.190 ± 0.002 mg/L) were found to be the predominant phenolic constituents in lemongrass. Total phenolics, total flavonoids, and antioxidant activity (IC50) values of the lemongrass extract were 26.73 mg GA/g, 8.06 mg Quercetin/g, and 2751.331 mg/L, respectively. The beads were spherical in shape with a 35.03-nm average particle diameter and 47.81% microencapsulation efficiency. The pH of the supplemented kashks decreased during the storage time. They showed lower acid degree values than the control at the end of storage. The peroxide, p-anisidine, and thiobarbituric acid values of the sample fortified with microencapsulated lemongrass extract were 6.15, 4.76, and 44.12%, respectively, being the lowest among the samples. This kashk sample had the highest hardness (570.62 ± 21.87 g), adhesiveness (18.10 ± 4.36 mJ), and cohesiveness (0.56 ± 0.25) but the lowest chewiness (72.66 ± 3.08 mJ) among the samples. It also had a better sensory profile than the control samples.

Our results indicated that microencapsulated lemongrass extract could be incorporated into kashk to ensure suitable sensorial and textural properties. Furthermore, it may delay fat oxidation and lipolysis during storage.
The Advent of Upgrading Schemes in Urbanizing Traditional Settlements of Botswana: Case of Kanye Village
Authors: Minyoi Mutakela
Published: January 2023

Botswana is a country with one of the fastest urbanizing population in sub-Saharan Africa with over 60% of its population living in cities, towns and urban villages. Botswana consists of several urbanizing traditional settlements within its settlement system, which have over the years transformed in terms of size, morphology and economic structures. The policy intervention processes and the resultant physical configuration within these urbanizing traditional settlements is testimony to the political economy of Botswana’s history. Contemporary planning as a key policy intervention process, in these urbanizing traditional settlements, however, provides the space for contest between formal planning based on ‘northern-derived theory’ and indigenous planning practices. Thus, the advent of Upgrading Schemes, as part of this contemporary planning, brings to the fore this contestation. This paper traces the case of an Upgrading Scheme for Kanye village, articulating its relevance, shortcomings and limitations to effect change, and so proposes a policy framework within which the upgrading schemes could be formulated and undertaken in Botswana.

(Ré)écriture de l’histoire de la colonisation et engagement littéraire dans quelques romans marocains contemporains
Authors: Elqadery Abderrahman
Published: January 2023

The writing of history of the colonial period in the contemporary Moroccan historical novel is performative and highlights the literary commitment of Moroccan writers of the new generation. Even if it is expressed tacitly, the committed part of the texts studied is highlighted by the questioningof an incomplete official historiography. The revisit of the colonial period brings out the voices of the authors in the narrative framework and involves the reader in the reflection on History. The literary commitment of our writers is manifest in the expression of anti-colonialism. This process of colonization is maintained throughout the corpus to such an extent that it becomes a leitmotif that runs through the stories studied and displays the ideological discourses of the writers and consequently theirliterary commitment.
Voix/es de la poésie. Valérie Rouzeau entre lectures publiques, chanson et théâtre
Authors: Pollicino Simona
Published: January 2023

The French poet Valérie Rouzeau’s work can be considered an example of writing beyond the text thanks to its “extensive”speech and its versatile rhythm, whether sung, played or danced. Both collective and interactive, Rouzeau’spoetry sinks into experience and goes off the beaten paths. This article aims not to separate what engages the body and the language for some remarks and analyses as close as possible to the linguistic, artistic and social practices by which Rouzeau’s living poems are promoted.
