Authors: Bhave Anushka , Van Delden Josephine , Gloor Peter A. , Renold Fritz R
Published: July 2023

This paper presents preliminary research that investigates the relationship between the flow of a group of jazz musicians, quantified through multi-person pose synchronization, and their collective emotions. Building upon previous studies that measured the physical synchronicity of team members by tracking their body movements and measuring the difference in arm, leg, and head movements, we introduce a novel metric termed "team entanglement". We employ facial expression recognition to evaluate the musicians’ collective emotions. Through correlation and regression analysis, we establish that higher levels of synchronized body and head movements correspond to lower levels of disgust, anger, sadness and higher levels of joy among the musicians. Furthermore, we utilize a Convolutional Neural Network (CNN) based deep learning model to predict the collective emotions of the musicians. This model leverages 17 body synchrony keypoint vectors as features, resulting in a training accuracy of 61.47% and a test accuracy of 66.17%.

Published: July 2023

A nanocomposite rod-shaped structure with single-walled carbon nanotube (SWCNT) embedded in polypyrrole (PPy) doped with nonafluorobutanesulfonic acid (C4F), SWCNT/C4F-PPy, was synthesized using emulsion polymerization. The hybrid ink was then directly coated on a polyimide film interdigitated with the Cu/Ni/Au electrodes via a screen-printing technique to create a flexible film sensor. The sensor film showed a response of 1.72% at 25 °C/atmospheric pressure when acetone gas of 5 ppm was injected, which corresponds to almost 95% compared to the Si wafer-based array interdigitated with the Au electrode. Additionally, C4F was used as a hydrophobic dopant of PPy to improve the stability of humidity and to produce a highly sensitive film-type gas sensor that provides stable detection even in humid conditions.

This article discusses the results of fluid inclusions study in barite collected at the Jan Mayen vent field area (Troll Wall and Perle & Bruce) and Loki’s Castle vent field of the Mohns Ridge segment of the Arctic Mid-Ocean Ridge. Three mafic-hosted volcanogenic massive sulfide deposits were examined within the active vent fields that adequately correspond to geological settings of ultraslow-spreading ridges and PT-conditions. Hydrothermal sediments were investigated to determine the temperature and salinity of the fluids responsible for barite precipitation. The hydrothermal origin of the barite was confirmed by its morphology. Fluid inclusions are two-phase and homogenized into the liquid phase on heating at temperatures below 287ºC. The salt concentration in fluids trapped in inclusions is 2.6–4.4 wt.% NaCl eq. The crystallization temperatures varied from 276ºС to 119ºС and from 307ºС to 223ºС for the Jan Mayen and Loki’s Castle vent fields, respectively. The data obtained allowed us to confirm evidence of fluid phase separation in the hydrothermal systems and to expand our knowledge of the temperature and salinity of mineral fluids previously known from recent direct measurements during the cruises within the G.O. Sars research vessel. The fluid inclusions data obtained from barites emphasize the fluid features characteristic of volcanogenic massive sulfide deposits, the similarities and differences for the studied hydrothermal sites, and allow comparisons with similar products from other active hydrothermal systems.

Introduction: This study aims to characterize changes in biogenic amines patterns in glioblasto-ma patients undergoing surgery and concurrent chemoradiation to illustrate how this class of metabolites changes during different stages of standard care treatment protocol.
Methods: We examined 138 plasma specimens (before surgery, 2 days after surgical resection, before starting concurrent chemoradiation, immediately after chemoradiation, and after adju-vant chemotherapy treatment) from 36 patients with isocitrate dehydrogenase (IDH) wildtype glioblastoma. Untargeted GC-TOF mass spectrometry-based metabolomics of biogenic amines was used given its superiority for identifying and quantitating small metabolites; this yielded 340 structurally identified metabolites.
Results: Comparing post-surgery to pre-surgery showed increased level of 12 metabolites: Gly-codeoxycholic acid (P=7.79E-05), Betonicine (P=9.23E-05), Glycocholic acid (P=3.18E-03), 3-Cysteinylaectaminophen (P=4.95E-03), S-Methyl-3-thioacetaminophen (P=5.77E-03), Tau-rocholic acid (P=9.97E-03), N-glycine (P=0.0013), p-acetamidophenyl.beta.-D-glucuronide (P=0.0048), 2-Hydroxy-5-sulfopyridine-3-carboxylic acid (P=0.0074), Acetaminophen sulfate (P=0.0095), 2-Amino-3-methoxybenzoic acid (P=0.02), and Dehydrofelodipine (P=0.024). There were 11 compounds that were downregulated, which included Mannitol (P=1.96E-19), Sorbitol (P=2.75E-019), Linoleic acid (P=1.51E-10), 1-Methylnicotinamide (P=1.78E-09), Nudifloramide (P=2.81E-08), Hexadecanedioic acid (P=5.49E-05), 3-Hydroxybutyric acid (P=0.0002), Riluzole (0.0036), Bupivacaine (P=0.0041), Lactitol (P=0.008), and 1-hydroxymidazolam.beta.-D-glucuronide (P=0.0414). After chemoradiation, significant de-crease was uncovered in Famotidine (P=0.0074), N-Isovalerylglycine (P=0.012), and 3-Methylcrotonylglycine (P=0.0131). While significant increase was detected in N-Methylisoleucine (P=0.0011), 4-Methyl-5-thiazoleethanol (P=0.042), and 6-Hydroxycaproic acid (P=0.049). Ensemble learning models, specifically random forest (RF) and AdaBoost (AB), accurately classified treatment phases with high accuracy (RF: 0.81 ± 0.04, AB: 0.78 ± 0.05). One significant insight gleamed from these models were that the metabolites Sorbitol and N-methylisoleucine were identified as important predictive features and confirmed by SHAP analysis.
Conclusion: To our knowledge, this is the first study to describe plasma biogenic amines signa-tures during different treatment phases in patients with glioblastoma. A larger study is needed to confirm the results and the potential application of this algorithm for classification of treatment responses.
Meta-Analysis of the Mechanisms Underlying COVID-19 Modulation of Parkinson’s Disease
Authors: Zhang Jonathan , Bishir Muhammed , Barbhuiya Sharman , Chang Sulie L
Published: July 2023

Coronavirus Disease-19 (COVID-19) is caused by the infection of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). The virus enters host cells through receptor-mediated endocytosis of angiotensin-converting enzyme-2 (ACE2), leading to systemic inflammation, also known as a “cytokine storm,” and neuroinflammation. COVID-19’s upstream regulator, interferon-gamma (IFNG), is downregulated upon the infection of SARS-CoV-2, which leads to the downregulation of ACE2. The neuroinflammation signaling pathway (NISP) can lead to neurodegenerative diseases, such as Parkinson's disease (PD), which is characterized by the formation of Lewy Bodies made of α-Synuclein protein encoded by synuclein alpha (SNCA). This study presents the pathways involved in the downregulation of ACE2 following SARS-CoV-2 infection and its effect on PD progression. Through QIAGEN’s Ingenuity Pathway Analysis, the study identifies the NISP as a top-five canonical pathway/signaling pathway and SNCA as a top-five upstream regulator. Core Analysis was also conducted on the associated molecules between COVID-19 and SNCA to construct a network connectivity map. The Molecule Activity Predictor tool was used to simulate the infection of SARS-CoV-2 by downregulating IFNG, which leads to the predicted activation of SNCA, and subsequently PD, through a dataset of intermediary molecules. Downstream Effect analysis was further used to quantify the downregulation of ACE2 on SNCA activation.
Minor and Major Deformations. Equations of Equilibrium of a Planar Domain with an Angular Cutout of the Boundary
Authors: Frishter Lyudmila
Published: July 2023

Large values and gradients of stresses and deformations, triggering concentrations of stresses and deformations, arise in the corner areas of a structure. The action of forced deformations, leading to the finite rupture of the contact between the elements of a structure, also triggers the concentration of stresses, while the rupture reaches an irregular point, a line on the area boundary. The theoretical analysis of the stress-strain state (SSS) of areas with angular cutouts in the boundary under the action of discontinuous forced deformations is reduced to the study of singular solutions to the homogeneous problem of the elasticity theory that has power-related features. The calculation of stress concentration coefficients in the domain of a singular solution to the elastic problem makes no sense. It is experimentally proven that the zone, that is close to the vertex of the angular cutout in the area boundary, has substantial deformations, rotations, and it corresponds to rising values of the first and second derivatives of displacements along the radius in cases of sufficiently small radii in the neighbourhood of the irregular point of the boundary. For such areas, it is necessary to consider the plane problem of the elasticity theory, taking into account the geometric nonlinearity under the action of forced deformations. This will allow analyzing the effect of relations between orders of values of deformations, rotations, and forced deformations on the form of the equation of equilibrium. The purpose of this work is to analyze the effect of relations of deformation orders, rotations, forced deformations on the form of the equilibrium equation in the polar coordinate system for a V-shaped area under the action of forced temperature-induced deformations with regard for the geometrical non-linearity and physical linearity.
Photoswitchable Molecular Units with Tunable Non-Linear Optical Activity: A Theoretical Investigation

Published: July 2023

A series of derivatives, involving two dithienylethene (DTE), groups, connected by several molecular linkers (bis(ethylene-1,2-dithiolato)Ni- (NiBDT), naphthalene, quasilinear oligothiophene chains) are investigated with the aid of computational quantum chemistry methods. This involves the computation of the second- and third-order nonlinear optical properties, i.e. molecular hyperpolarizabilities of the designed/selected derivatives. These properties can be efficiently controlled by DTE switches, in connection with light of appropriate frequency. We found that NiBDT, as a linker, is associated with a greater contrast, in comparison to naphthalene, between the first and second hyperpolarizabilities of the “open-open” and the “closed-closed” isomers. This is explained by invoking the low lying excited states of NiBDT. It has been found that the second hyperpolarizability can be used as an index, which follows the structural changes induced by photochromism. The two-photon absorption, which is related to the imaginary part of second hyperpolarizability, has also been investigated for the S0S1 transition. Furthermore, the intramolecular excited-state energy transfer (EET) is studied as well as the overlap between the absorption and emission spectra of the donor and acceptor groups of the molecules. The electronic coupling, VDA, between the donor and acceptor fragments, as well as the emission spectrum of the donor and the absorption spectrum of the acceptor have been computed, assuming a Förster type transfer mechanism. EET is a critical factor governing the photochromism. Two methods were used to compute VDA, one based on linear response and one based on the distributed multipole analysis (DMA); both techniques give very similar results for the dominating Coulomb contribution. For NiBDT as the linker a low VDA value has been computed. We found that VDA is affected by the molecular geometry. Our results clearly show that the linker strongly influences the communication between the open-closed DTE groups and thus, photochromism. The present computations show that full photochromism is attained in derivatives where two DTE groups are linked by a tetrathiophene chain, in agreement with experiment. The sensitivity of molecular linear and nonlinear optical properties upon photochromism can assist with the identification of the molecular isomers.
Cyclophilin D in Mitochondrial Dysfunction: a Key Player in Neurodegeneration?
Authors: Coluccino Gabriele , Muraca Valentina Pia , Corazza Alessandra , Lippe Giovanna
Published: July 2023

Mitochondrial dysfunction plays a pivotal role in numerous complex diseases. Understanding the molecular mechanisms by which the “powerhouse of the cell” turns into the “factory of death” is an exciting yet challenging task that can unveil new therapeutic targets. The mitochondrial matrix protein CyPD is a peptidylprolyl cis-trans isomerase involved in the regulation of the permeability transition pore (mPTP). The mPTP is a multi-conductance channel in the inner mitochondrial membrane whose dysregulated opening can ultimately lead to cell death and whose involvement in pathology has been extensively documented over the past few decades. Moreover, several mPTP-independent CyPD interactions have been identified, indicating that CyPD could be involved in the fine regulation of several biochemical pathways. To further enrich the picture, CyPD undergoes several post-translational modifications that regulate both its activity and interaction to its clients. Here, we will dissect what is currently known about CyPD and critically review the most recent literature about its involvement in neurodegenerative disorders, focusing on Alzheimer’s Disease and Parkinson’s Disease, supporting the notion that CyPD could serve as a promising therapeutic target for the treatment of such conditions. Notably, significant efforts have been made to develop CyPD-specific inhibitors, which hold promise for the treatment of such complex disorders.

Published: July 2023

Plasma-activated water (PAW) is an emerging and promising green technology in the agriculture sector during recent years. The aim of this study was to examine the influence of the spraying of PAW and amino acid fertilizer concentrations on the physiological, biochemical and phytochemical characteristics of German chamomile varieties under field conditions. Method: The experiment was performed during 2020–2021 as a factorial using a randomized complete block design with three replications, in an arid and warm region. The factors contained five fertilizer levels (0 (control), 1, 2, 3 ml·L−1 amino acid and PAW) and three German chamomile cultivars Bona, Bodegold, Lianka). Physiological, biochemical and phytochemical traits such as plant height, fresh and dried flower weight, chlorophyll a, b, carotenoids, CHN elements, C:N ratio, total protein, amino acid profile, essential oil yield, apigenin content and major secondary metabolites were examined. Results: The ANOVA indicated that the impact of the cultivar and fertilizer was significant on all physiological, biochemical and phytochemical studied parameters. The amino acid fertilizer and PAW enhanced physiological features, hydrogen, C:N ratio, essential oil yield, apigenin content and main phytochemical compositions like chamazulene and α-bisabolol, but it had no incremental effect on the carbon, nitrogen, and total protein percentage. Conclusion: Findings revealed that the application of foliar amino acid fertilizer and PAW treatments improves physiological, biochemical and phytochemical parameters in German chamomile cultivars under field conditions.
Developing Circular Business Model for Machinery Lifecycle Extension by Exploiting Tools for Digitalization
Authors: Cappelletti Federica , Menato Silvia
Published: July 2023

Digitalization technologies have been identified as enablers for the adoption of Circular Economy practices. The machinery value chain, addressed in this study, is affected by the introduction of digital technologies that enable real-time monitoring data on product condition and control optimization deploying predictive analytics techniques, as well as the offerings of circular-based services. Machinery lifetime extension can be digitally enabled on both old and new machines. The research objectives were to investigate how digital technologies enable the adoption of circular economy-based business models in manufacturing companies and provide an answer about i) what Life Cycle Extension Strategy is suitable for digital circular business model adoption and ii) how digitalization of machines enables manufacturing companies to innovate their business model. The correlation matrix is the tool developed from the proposed approach; it aims at supporting manufacturers in the very first contact with circular business models. In the context of the European RECLAIM project, two manufacturers apply the approach, proving its validity and wide applicability. The next steps are expected to introduce quantitative indicators to define thresholds for the steps toward circularity, without replacing the qualitative approach, as it guarantees the wide applicability of the approach in context that never considered circularity yet.

Published: July 2023

Adolescents’ eating disorders and disordered eating behaviours appear to be a growing public health concern. The aetiology of these conditions is complex, as many different factors interact for their development. Among them, family factors such as parenting styles and comments regarding weight from family members are considered critical and are extensively researched. However, the impact of parental dieting has received less attention. A literature review was conducted in order to examine the relationship between parental engagement in weight-reduction dieting and their adolescent offspring’s disordered eating behaviours. The review was conducted in three databases (PubMed, Scopus and Google Scholar). A number of studies indicated that adolescents whose parents were engaged in dieting in order to lose weight are more likely to showcase disordered eating behaviours. However, research about this relationship is very scarce. More studies on the link between parental eating and dieting habits and the risk of disordered eating in adolescents are needed. Moreover, parents should be informed regarding the possible risks when they choose to follow weight-loss diets and the importance of adopting healthy eating and weight-control habits for the whole family.

Published: July 2023

Background:

Total knee arthroplasty (TKA) is a highly successful surgical procedure that decreases pain and improves function. Many patients who undergo TKA may require surgical intervention on both extremities because of bilateral osteoarthritis. The purpose of this study was to evaluate the safety of simultaneous bilateral TKA compared with that of unilateral TKA.

Methods:

Patients who underwent unilateral or simultaneous bilateral primary, elective TKA from 2015 to 2020 were identified using the Premier Healthcare Database. Subsequently, the simultaneous bilateral TKA cohort was matched to the unilateral TKA cohort in a 1:6 ratio by age, sex, race, and presence of pertinent comorbidities. Patient characteristics, hospital factors, and comorbidities were compared between the cohorts. The 90-day risks of postoperative complications, readmission, and in-hospital death were assessed. Differences were assessed using univariable regression, and multivariable regression analyses were performed to account for potential confounders.

Results:

Overall, 21,044 patients who underwent simultaneous bilateral TKA and 126,264 matched patients who underwent unilateral TKA were included. After accounting for confounding factors, patients who underwent simultaneous bilateral TKA demonstrated a significantly increased risk of postoperative complications, including pulmonary embolism (adjusted odds ratio [OR], 2.13 [95% confidence interval (CI), 1.57 to 2.89]; p < 0.001), stroke (adjusted OR, 2.21 [95% CI, 1.42 to 3.42]; p < 0.001), acute blood loss anemia (adjusted OR, 2.06 [95% CI, 1.99 to 2.13]; p < 0.001), and transfusion (adjusted OR, 7.84 [95% CI, 7.16 to 8.59]; p < 0.001). Patients who underwent simultaneous bilateral TKA were at increased risk of 90-day readmission (adjusted OR, 1.35 [95% CI, 1.24 to 1.48]; p < 0.001).

Conclusions:

Simultaneous bilateral TKA was associated with increased rates of complications including pulmonary embolism, stroke, and transfusion. Orthopaedic surgeons and patients should consider these potential complications when contemplating simultaneous bilateral TKA. When simultaneous bilateral TKA is pursued, patient counseling and thorough medical optimization should be performed.

Published: July 2023

Case:

An adolescent female dancer with excessive femoral anteversion presented with posterior and anterior hip pain aggravated by poses that required extension and external rotation. Imaging revealed an atypical cam deformity of the posterior head-neck junction. During surgery, the posterior head-neck junction was observed to impinge on the posterior acetabulum with anterior subluxation of the hip. After a derotational femoral osteotomy, the patient experienced resolution of her symptoms.

Conclusion:

Excessive femoral anteversion can lead to reactive cam deformity, posterior intra-articular impingement, and anterior hip instability in patients who require repetitive hip extension and external rotation, such as ballet dancers.

This research stems from one of the judges' decisions at the Religious Court of Kediri Regency which decided ex-officio civil cases, namely deciding cases that were not in the petitum. This started because one of the litigants has limited information and knowledge of legal rights. This study aims to analyze the actions of judges in implementing ex-officio authority in terms of civil procedural law and the ex aequo et bono principle. The research method used is a qualitative method of literature with a juridical-normative approach. Data collection techniques using documentation and interview. From the data analysis, concluded that first, in terms of civil procedural law, the judge's actions in ex-officio decisions do not violate one of the principles of civil procedural law, namely the ultra petita principle. Second, in terms of the ex aequo et bono principle, the action of the panel of judges to decide ex-officio in this case, is in accordance with what is stated in the ex aequo et bono principle that judges can get out of rigid legal provisions as long as this is done for the protection of somebody rights, in this case to protect the rights of the wife and children after divorce.

Penelitian ini membahas tentang salah satu putusan hakim di Pengadilan Agama Kabupaten Kediri yang memutus perkara perdata secara ex-officio yaitu memutus perkara yang tidak ada dalam petitum atau tuntutan. Sebab salah satu pihak yang berperkara memiliki keterbatasan informasi dan pengetahuan mengenai hak-hak hukum. Penelitian ini bertujuan untuk menganalisis tindakan hakim dalam menerapkan kewenangan ex-officio ditinjau dari hukum acara perdata dan asas ex aequo et bono. Metode penelitian yang digunakan adalah metode penelitian kualitatif  dengan pendekatan yuridis-normatif. Teknik pengumpulan data menggunakan teknik dokumentasi.

: Marriage raises the rights and obligations of husband and wife, but there is a perception of the obligation for the wife to work to provide for the family. The uniqueness is that a wife who doesn't work for a living will get stereotyped by society. The point of the problem is what is the perspective of Imam Shafi'i and liberal feminism regarding the rights and obligations of women as breadwinner wives in the Panjen Complex, Petung Hamlet, Tempuran Village, Sawoo District, Ponorogo Regency. This research is a field research with a qualitative approach. The results of the study concluded: first, according to Imam Shafi'i, the rights of a wife are appropriate, including material maintenance, dowry, and part of spiritual maintenance. The wife's obligations according to Imam Shafi'i, the wife informants had carried out their obligations as wives, namely obeying their husbands and providing services to their husbands. Still, there were discrepancies related to domestic obligations. Second, rights according to liberal feminism, the wife, as a rational being who prioritizes rights over goodness, does not get her right to choose her role (housewife) because she obeys the prestige (compulsion) of the stereotypes that come to her.

Pernikahan menimbulkan hak dan kewajiban suami istri, namun terdapat persepsi kewajiban bagi istri untuk wajib bekerja mencari nafkah keluarga. Keunikannya adalah di mana istri yang tidak ikut mencari nafkah dia akan mendapatkan stereotip oleh masyarakat. Titik permasalahannya yakni bagaimana perspektif Imam Shāfi’ī dan feminisme liberal tentang hak dan kewajiban perempuan sebagai istri pencari nafkah di Komplek Panjen Dusun Petung Desa Tempuran Kecamatan Sawoo Kabupaten Ponorogo. Penelitian ini merupakan penelitian lapangan (field research) dengan pendekatan kualitatif. Hasil penelitian menyimpulkan: pertama, hak istri menurut Imam Shāfi’ī sudah sesuai, meliputi nafkah kebendaan, mahar, dan sebagian nafkah batin. Kewajiban istri menurut Imam Shāfi’i, para informan istri telah melaksanakan kewajibannya sebagai istri yakni taat pada suami, dan memberi pelayanan kepada suami, namun terdapat ketidaksesuaian yakni terkait kewajiban domestik. Kedua, hak menurut feminisme liberal, istri sebagai makhluk yang rasional yang memprioritaskan hak dari pada kebaikan tidak mendapatkan haknya untuk memilih perannya (ibu rumah tangga) disebabkan menuruti gengsi (keterpaksaan) akan stereotip yang datang padanya.

Published: July 2023

Natural gas hydrate (NGH) is an important alternative energy resource to achieve carbon neutral. The developmental trend and competitive landscape of NGH exploitation and production play a crucial role for policymakers in government, managers of enterprises, and science researchers. This paper proposes a new framework to carry out in-depth analysis of NGH by combining patentometrics, technologies evolution and correlation relationships to monitor developmental tends and competitive landscape using patent analysis. The results show that China, the US, and Japan hold a clear advantage using patents analysis. The current technological development in NGH field is more oriented towards extraction technologies, equipment, and processing systems. The co-opetition analysis among countries reveals that the largest international cooperation network is mainly in Europe and the United States, while national partnerships in Asia are mainly in China and Japan. The cooperation among institutions is still low and occurs mainly within universities in China, whereas both the US and Japan have cooperation between enterprises. The competitive landscapes of NGH-related key technologies among countries and institutions are also discussed. This study not only contributes to monitoring the developmental trend and competitive landscape in NGH but also provides policy recommendations for the government and enterprises on strategic management and collaborative innovation.
Transition to agroecology promotes mutualistic and reduces antagonistic fungi in lettuce roots

Published: July 2023

Efficient and sustainable food production constitutes a significant challenge. Conventional agriculture involves the regular application of pesticides and fertilizers, with a wide range of negative externalities including the compromise of ecosystems stability, pernicious effects on human health, and social problems. These practices may negatively affect soil microorganisms including two groups of widely distributed plant root mutualists: arbuscular mycorrhizal fungi (AMF) and dark septate endophytic fungi (DSEF). These fungi improve host plant nutrition and growth, and protect them against stress. Agroecology has emerged as a demand for a paradigm shift in productive systems and involve the reduced or null inputs of agrochemicals that are replaced by ecological services provided by biodiversity and biotic interactions. Notwithstanding, the knowledge on how agroecological practices affect crops interactions with belowground mutualists and antagonists is limited. In this study, we evaluated through direct observation and molecular methods, the abundance and diversity of mutualistic -AMF and DSEF- and the abundance of antagonistic fungi Olpidiaster brassicae (ex Olpidium) in lettuce roots cultivated in transition to agroecology (TA) and conventional horticulture (CH) fields located in central Argentina. We found that TA, mainly through avoiding agrochemical applications, increased root colonization levels of AMF and DSEF, molecular sequences abundance of AMF, and diversity of both mutualists while decreased percentage of colonization of the pathogen O. brassicae in lettuce. Therefore, through their effects on soil fungi, agroecological managements could benefit plant growth and health.

Published: July 2023

Background: Knee osteoarthritis engenders a profound societal and economic burden while significantly compromising the well-being of patients. Present clinical guidelines advocate for non-pharmacological conservative approaches encompassing exercise, health education, and weight reduction as pivotal therapeutic modalities. Notably, mind-body exercises such as Taichi and Yoga are highly recommended due to their substantial efficacy in alleviating knee osteoarthritis (KOA). However, the comparative evaluation of these exercises remains insufficient. Consequently, the objective of this study is to assess the efficacy and safety of Taichi and Yoga while exploring the level of acceptance among patients.
Methods: This pilot trial adopts a randomized, controlled, and blinded design, both for the assessor and statistician. A total of 72 participants will be recruited and randomly assigned to either the Taichi group (n = 36) or the Yoga group (n = 36). The Taichi group will undergo an 8-week intervention involving Modified Eight-Stage Taichi therapy, followed by a 16-week follow-up period. On the other hand, the Yoga group will receive an 8-week intervention employing Hatha Yoga therapy, followed by a 16-week follow-up period.

Objectives: The aim of this study was to evaluate the outcomes of pulpotomies performed using a newly-developed, premixed, injectable calcium silicate cement with flowable consistency, compared to mineral trioxide aggregate (MTA) in mature permanent teeth with reversible pulpitis.
Materials and methods:Mature permanent teeth that met the inclusion criteria were randomly divided into two groups according to pulpotomy material (ProRoot MTA group, Endocem MTA Premixed group).
After pulp exposure, the superficial pulp was either removed to a depth of 2 mm (partial pulpotomy) or completely amputated to the level of the root canal orifice (full pulpotomy). A 3-mm layer of either material was randomly placed over the pulp wound, followed by the application of a thin layer of a light-cured glass ionomer composite liner. The restoration procedure was then carried out during the same visit.
Results: Out of the total 87 teeth enrolled, 71 teeth (37 in the ProRoot MTA group and 34 in the Endocem MTA Premixed group) were clinically and radiographically evaluated at one year. The overall pulpotomy success rate was 94.4% (67/71); 93.9% in the ProRoot MTA and 97.1% in Endocem MTA Premixed with no significant difference between the groups. Calcific bridge formation occurred in 6 (24.0%) cases in the ProRoot MTA group and 10 (40.0%) cases in the Endocem MTA Premixed group.
Conclusions: Endocem MTA Premixed is a viable alternative to ProRoot MTA for single-visit pulpotomies of permanent molars.
Clinical Relevance:Premixed injectable calcium silicate cement with flowable consistency can be considered as a potential alternative to MTA cement for single-visit pulpotomies.

A robust optimal scheduling method driven by multi-objects is proposed for the collaborative optimization problem between dynamic scheduling, preventive maintenance of equipment, and robustness of scheduling schemes in a complex manufacturing system. Firstly, the equipment maintenance task is mapped to the process level, and composite dispatching rules with weight parameters are designed, which flexibly consider equipment maintenance and system processing status. Secondly, the performance-driven ideology is analyzed through two models based on the IWOA-MLP algorithm. Thirdly, the feedback mechanism ideology facilitates adaptive closed-loop optimizations. Finally, a series of experiments were carried out on the simulation platform of a semiconductor manufacturing enterprise in Shanghai. The experimental results show that the proposed robust optimal scheduling system can effectively deal with mixed uncertainty, improve production performances, and maintain highly robust measures.

Indonesia is known as the fourth biggest coffee producing countries in the world. There are over 124 species within the Coffea family, however, only arabica (C. arabica L.) and robusta (C. canephora) have played an immense economic role. The region of Aceh; especially the Gayo highlands [800- 2,200 m. above sea level (a.s.l.)] is known as the largest arabica coffee plantation across the nation, and an average production of 700 up to 800 kg
ha-1, and produce almost 25% of the total arabica coffee at the national level. This is the first publication about the genetic diversity of coffee arabica (Coffea arabica L.) cultivated on the Gayo Highlands, although it was already existed almost two centuries. Based on history, the Dutch initially introduced coffee to Aceh in the early of 18th century. There were up to 52 accessions of coffee arabica and their genetic diversities were measured via their (i) morphological characteristics (n= 33 traits); (ii) their simplification bi-plot diagram via Principle Component Analyses (PCA); (iii) molecular variation via Simple Sequence Repeat (SSR) marker (n= 8). Our result showed that high morphological diversities was existed, although, low to moderate genetic diversity was confirmed among those commercial accessions based on these parameters: the PCA biplot diagram, and dendrogram, Polymorphic Information Content (PIC) that showed a range of 0.00-0.84, and 0.157-0.610, respectively. By conducting genetic diversity study intended for local germplasm conservation, a sustainable coffee production in Middle Aceh, and their economic benefits could be still maintained for a long term.

For the problem of space dynamic target tracking with occlusion, this paper proposes an online tracking method based on the combination between the five-frame difference and Deepsort (Simple Online and Realtime Tracking with a Deep Association Metric) to achieve the identification first and then tracking of the dynamic target. First of all, with the basis of the three-frame difference, the five-frame difference is designed, and through the integration with the background subtraction of ViBe-based (Visual Background Extraction), the accuracy and anti-interference ability are enhanced; Secondly, the YOLOv5s (You Look Only Once) is improved using preprocessing of DWT (Discrete Wavelet Transformation) and injecting Global Attention Module (GAM), which is considered as the detector for Deepsort, and while solving the loss for target easy to in occlusion situations, the real-time and accuracy can be strengthened; Lastly, in contrast with other methods and cross-validation experiments of datasets, the improved method in this paper is verified for effectiveness and superiority. Simulation results show that the proposed space dynamic target tracking can keep stable to track all dynamic targets under the occlusion, and the tracking precision is improved to 93.88%, accuracy of 71%. Finally, there is a combination with the physical depth camera D435i, experiments on target dynamics and occlusion show the effectiveness and superiority of the proposed recognition and tracking algorithm in the face of dynamic and occlusion.
Early Modulated Proton Therapy (EMPT) at FLASH Dose Rates: Proton Bursts Optimization, Stochastic Cooling, Spatial Intensity and Energy Modulations
Authors: Wang Kelin
Published: July 2023

FLASH radiotherapy requires extremely high dose rate (DR > 40Gy/s) hence challenges prevalent external-beam technologies. To achieve FLASH DRs, proton accelerators are potentially the best candidates due to high kinetic energies for individual protons. However, as the major drawback of prevalent IMPT, the lengthy pencil-beam modulation is the key difficulty against FLASH DR. To resolve this, we relinquished pencil-beam modulation at treatment end, and proposed early modulation proton therapy (EMPT) for renovated proton synchrotrons. The EMPT procedures could be divided into 4 steps. First, proton beam (differentiated into bursts of certain sizes) for the entire radiotherapy treatment is injected into the synchrotron and accelerated. This pre-load design allows delivery time in microseconds, meeting the FLASH DR. Second, general stochastic cooling for primitive beam-bursts inside SSR using feedback loops. Third, spatial intensity modulation for each beam-burst inside SSR, the tumor-specific fine-tuned of step second. Fourth, energy modulations at exit pipelines, either by altering the magnetic field or implementing a voltage pulse gap. Early modulated proton bursts could stay in the SSR for 10-20min or longer without damping, thus EMPT fluences can be pre-loaded/generated and stored in SSR during patient setup. For each treatment plan, the TPS provides information on optimized burst size (minimal dose unit for EIMPT), burst numbers (calculated by prescription, tumor size), primitive energy, length of spread-out Bragg Peak etc. hence the early-modulation procedures could be performed inside SSR. Relinquishing pencil-beam in IMPT is fundamental to achieve FLASH DR. Implementing advancement of technologies in modern particle physics experiments, for the first time, EMPT was proposed, allowing pre-loaded, early modulated proton beams to satisfy FALSH Radiotherapy.
Behavior-related visual activations in the auditory cortex of nonhuman primates
Authors: Huang Ying , Brosch Michael
Published: July 2023

While it is well established that sensory cortical regions traditionally thought to be unimodal can be activated by stimuli from modalities other than the dominant one, functions of such foreign-modal activations are still not clear. Here we show that visual activations in early auditory cortex can be related to whether or not the monkeys engaged in audio-visual tasks, to the time when the monkeys reacted to the visual component of such tasks, and to the correctness of the monkeys’ response to the auditory component of such tasks. These relationships between visual activations and behavior suggest that auditory cortex can be recruited for visually-guided behavior and that visual activations can prime auditory cortex such that it is prepared for processing future sounds. Our study thus provides evidence that foreign-modal activations in sensory cortex can contribute to a subject’s ability to perform tasks on stimuli from foreign and dominant modalities.

Published: July 2023

Ultrasonic atomization technology has been widely used in industry in recent years due to its higher atomization efficiency. This paper proposes a method of electrostatic-assisted ultrasonic atomization spraying and designs a special ultrasonic power supply that can directly introduce high-voltage static electricity onto the surface of the ultrasonic atomization so that the liquid can contact the charge and enhance the charging effect. This paper conducts numerical simulation analysis on the atomization process and statistically analyzes the numerical simulation atomization particle size through image processing. In addition, this paper designs experiments from two aspects of atomization particle size and film-forming effect. The results show that the experimental results are consistent with the numerical simulation results, verifying the accuracy of the numerical simulation results. It shows that in the process of sub-droplet formation, the introduction of static electricity will increase the number of capillary waves, promote two mechanisms of the capillary pinch-off mechanism and the Rayleigh-Plain instability, reduce atomization particle size, and increase atomization efficiency. Compared with the traditional airflow beam method, the film-forming surface quality of the electric field beam method is higher and the surface roughness is lower. It solves the problem that airflow affects film-forming quality in traditional ultrasonic spraying with the airflow beam method. It provides a theoretical basis and scientific guidance for the application of electrostatic-assisted ultrasonic atomization technology in the atomization and film preparation industry.
