Prognosis of adrenalectomy guided by computed tomography versus adrenal vein sampling in patients with primary aldosteronism: A systematic review and meta‐analysis
Authors: Yan Yi , Sun Hui‐Wen , Qi Yue
Published: January 2022

Adrenal vein sampling (AVS) is recommended to be the gold standard for patients with unilateral subtypes of primary aldosteronism to clinical diagnosis and surgery therapy. However, it is uncertain whether AVS is better for prognosis than computed tomography (CT), which is the most widely used. Pubmed, Embase, and Cochrane Library were searched for articles with no start date restriction. The last search was conducted on Jun 15, 2021. Eligible studies compared the distinct subtypes of primary aldosteronism by AVS with CT (as a control group) and reported the prognosis at follow‐up. Evaluation of cohort studies referred to Newcastle ‐ Ottawa Quality Assessment Scale, and randomized controlled trials referred to Updated Cochrane Collaboration tool. A random‐effect model or fixed‐effect model was chosen according to the heterogeneity test. All processes were performed following the PRISMA 2020 statement. Eleven studies were identified, including 1325 patients based on AVS and 907 patients based on CT. Compared with patients guided by CT, patients who underwent AVS had an increased possibility of complete biochemical success (odds ratio [OR] 2.78, 95% CI 1.88–4.12) and a decreased chance of absent biochemical success (OR 0.23, 95% CI 0.13–0.40) at follow‐up. Nevertheless, the rate of complete clinical success (OR 1.09, 95% CI 0.89–1.35) and absent clinical success (OR 0.96, 95% CI 0.68–1.33) had no significant difference. Therefore, distinguishing subtypes by AVS for early treatment may be crucial since it can promote biochemical improvement.

Published: January 2022

Abnormally expressed long non‐coding RNAs (lncRNAs) have been recognized as potential diagnostic biomarkers or therapeutic targets in non‐small cell lung cancer (NSCLC). The role of the novel lnc‐CYB561‐5 in NSCLC and its specific biological activity remain unknown. In this study, lncRNAs highly expressed in NSCLC tissue samples compared with paired adjacent normal tissue samples and atypical adenomatous hyperplasia were identified by RNA‐seq analysis. Lnc‐CYB561‐5 is highly expressed in human NSCLC and is associated with a poor prognosis in lung adenocarcinoma. In vivo, downregulation of lnc‐CYB561‐5 significantly decreases tumour growth and metastasis. In vitro, lnc‐CYB561‐5 knockdown treatment inhibits cell migration, invasion and proliferation ability, as well as glycolysis rates. In addition, RNA pulldown and RNA immunoprecipitation (RIP) assays show that basigin (Bsg) protein interacts with lnc‐CYB561‐5. Overall, this study demonstrates that lnc‐CYB561‐5 is an oncogene in NSCLC, which is involved in the regulation of cell proliferation and metastasis. Lnc‐CYB561‐5 interacts with Bsg to promote the expression of Hk2 and Pfk1 and further lead to metabolic reprogramming of NSCLC cells.

Published: January 2022

Background and Aim

Serum glycans are known to be good markers for the early diagnosis and prognostic prediction in many cancers. The aims of this study were to reveal the serum glycan changes comprehensively during the process of carcinogenesis from colorectal adenoma (CRA) to colorectal cancer (CRC) and to evaluate the usefulness of the glycan profiles as clinical markers for CRC.

Methods

Serum samples were obtained from 80 histologically proven CRC and 36 CRA cases. The levels of glycans in the serum were examined with a comprehensive, quantitative, high‐throughput unique glycome analysis, and their diagnostic and prognostic abilities were evaluated.

Results

Among 34 stably detected glycans, nine were differentially expressed between CRC and CRA. Serum levels of hybrid type glycans were increased in patients with CRC compared with those with CRA (P < 0.001), and both hybrid‐type and multi‐antennary glycans were significantly increased in advanced cancer cases. The glycan, m/z 1914, showed the highest diagnostic value among the decreased glycans, whereas m/z 1708 showed the highest among the increased glycans. The glycan ratio m/z 1708/1914 showed a higher area under the receiver operating characteristic curve (0.889) than any other single glycan or conventional tumor marker, such as carcinoembryonic antigen (0.766, P = 0.040) and carbohydrate antigen 19‐9 (0.615, P < 0.001). High m/z 1708/1914 was also correlated with an advanced cancer stage and short overall survival.

Conclusion

Serum glycans, especially the m/z 1708/1914 ratio, were useful for the diagnosis, staging, and prognosis prediction of CRC.
Preventing, mitigating, and managing future pandemics for people with an intellectual and developmental disability ‐ Learnings from COVID‐19: A scoping review
Authors: Taggart Laurence , Mulhall Peter , Kelly Rosie , Trip Henrietta , Sullivan Bill , Wallén Eva Flygare
Published: January 2022

Many people with an intellectual and developmental disability (IDD) are biologically, socially, and economically/politically vulnerable to developing SARS‐COV‐2 (COVID‐19) compared to the general population. Most governments have developed public‐health policies and strategies to address the challenges that COVID‐19 has presented. These policies and strategies have been based upon the general population and in fact could be detrimental to the health and well‐being of people with IDD. This paper provides a review of the key learning points emerging from the COVID‐19 literature, together with guidance for the provision of services and government interventions for people with an IDD for future pandemics. Using guidance from the Joanna Briggs Institute, a scoping review was used to explore the current literature (scientific and grey) on IDD and COVID‐19. Three core themes emerged from the review. Prevention/protection: User‐friendly accurate accessible information, handwashing and social distancing, Personal Protective Equipment, shielding, track and trace, testing, vaccine compliance/hesitancy, and training. Mitigation: Making reasonable adjustments both to where people live, and to community healthcare/clinical practice; and the use of technology as a pandemic‐response strategy. Treatment/Management: Access to acute hospitals and lifesaving equipment, using a suitable clinical fatality assessment instrument, stopping Do Not Resuscitate notices, individualised care plans and hospital passports, family/paid carers to support people in hospitals; and use of telehealth in clinical care. This is the first international scoping review that provides a narrative synthesis of emerging themes related to the COVID‐19 pandemic and people with an IDD. This paper highlights themes related to preventing, mitigating, and treating/managing the care of this population during the COVID‐19 pandemic, which can inform future public‐health policies. This paper also exposes the negative impacts of public‐health interventions in both High‐Income Countries and Low‐Middle Income Countries for this population including lapses in upholding human rights. These data provide a basis for learning from the COVID‐19 pandemic in planning for future pandemics.

Published: January 2022

The origin of sweetpotato, a hexaploid species, is poorly understood, partly because the identity of its tetraploid progenitor remains unknown. In this study, we identify, describe and characterize a new species of Ipomoea that is sweetpotato’s closest tetraploid relative known to date and probably a direct descendant of its tetraploid progenitor.

We integrate morphological, phylogenetic, and genomic analyses of herbarium and germplasm accessions of the hexaploid sweetpotato, its closest known diploid relative Ipomoea trifida, and various tetraploid plants closely related to them from across the American continent.

We identify wild autotetraploid plants from Ecuador that are morphologically distinct from Ipomoea batatas and I. trifida, but monophyletic and sister to I. batatas in phylogenetic analysis of nuclear data.

We describe this new species as Ipomoea aequatoriensis T. Wells & P. Muñoz sp. nov., distinguish it from hybrid tetraploid material collected in Mexico; and show that it likely played a direct role in the origin of sweetpotato’s hexaploid genome. This discovery transforms our understanding of sweetpotato’s origin.

Authors: Polonowita Ajith , Guan Guangzhao , Thomson W. Murray , Martin‐Hendrie Reuben
Published: January 2022

Aim

To investigate patient and clinician feedback on remote telehealth consultations to determine their feasibility for use as an adjunct service.

Methods

A cross‐sectional investigation of satisfaction with telehealth consultations. In total, one oral medicine specialist, four dentists and 88 patients were surveyed.

Results

A total of 88 video consultations were completed with patients in Christchurch and Wellington hospitals. There was always a dentist present with the patient during the consultation. Overall, 95.5% of patients found the experience to be comfortable, with no systematic differences by sex, age, ethnicity or reason for the visit. Most patients were satisfied with the treatment received during the video consultations. Fewer patients who presented with pain were satisfied with the treatment received than were those who presented with oral mucosal disorders or other issues (61.8%, 75.0% and 76.9%, respectively). Both the oral medicine specialist and clinicians involved found the process comfortable and did not find diagnostic capabilities to be compromised.

Conclusion

Video telehealth might be a valid alternative or adjunct to face‐to‐face consultations. This may open the way for remote video consultations to improve the availability of oral medicine services in rural areas.

Published: January 2022

Background

A questionnaire survey was conducted to clarify whether surgical treatments performed by a pediatric surgeon improve the quality of life (QOL) of caregivers (medical doctors, nurses, physical therapists, and nursery teachers) supporting neurologically impaired (NI) patients who work at specialized institutions.

Methods

The questionnaire survey was conducted with caregivers who cared for NI patients who underwent an operation at the Department of Pediatric Surgery, Kurume University Hospital. Quality‐of‐life related responses concerning the change of care after surgical procedures in NI patients were collected in addition to the background data related to caregivers and the surgical procedures performed for them. Degrees of difficulty in caring for NI patients and of the caregivers’ own QOL postoperatively were also compared.

Results

There were 192 valid responses. The majority of responses were from females and nurses aged in their 40s and 50s. The surgical procedure performed most often in the NI patients was gastrostomy. Of the respondents, 77% answered that the postoperative care became easier. The degrees of difficulty in caring for NI patients and the caregivers’ own QOL were significantly higher and lower, respectively, among physical therapists compared with caregivers in other occupations. Moreover, the QOL in respondents with factors related to a longstanding relationship with NI patients was significantly higher compared with the respondents without them.

Conclusion

This survey indicated that surgical procedures for NI patients might contribute to improved QOL for the caregiver by reducing the difficulty of caring for NI patients.

Published: January 2022

Soybean target spot, caused by the fungus Corynespora cassiicola, is an important disease in northwestern Argentina (NWA). A cultural, morphological, and virulence characterization of 24 C. cassiicola isolates from different geographic localities in NWA was performed. The isolates were classified into five different cultural phenotypes, one of which has not been previously described. The ribosomal DNA internal transcribed spacer region sequence from five representative isolates (587 bp) exhibited 100% identity with C. cassiicola. A high variability of conidial morphology was observed among isolates, but no correlation with cultural phenotype was observed. When the soybean cultivar A 8000 RG was challenged with the 24 isolates, different degrees of virulence were observed, ranging from highly virulent to nonvirulent. No association of virulence with cultural or morphological characters was observed, but a relationship with geographical origin was demonstrated. Histopathological studies were performed on a nonvirulent and a highly virulent isolate. Microscopic observations of infected tissues of the former showed low mycelium development restricted to the upper epidermis, a thickening of the cuticle and primary wall of subepidermal cells, and accumulation of callose in phloematic vessels. In tissue infected with the latter, there was abundant mycelium development accompanied by cellular disorganization in mesophyll cells. Pathological challenges of isolates on nine different cultivars indicated that the degree of virulence of isolates depends on the plant genotype, demonstrating that the C. cassiicola–soybean interaction is highly specific. Understanding the genetic basis of this interaction will provide new information for better disease management and breeding strategies.
The dentist as the gatekeeper of systemic health: A case report
Authors: Teicher Ross , Henschel Marc
Published: January 2022

Many in the dental field often practice with blinders—they focus on the decay in front of them, the crown that must be prepared, the canal that must be shaped. The series of events that led to that existing issue, the underlying habit, disease, etc. is often overlooked. Many in our profession have gotten into the habit of becoming “tooth mechanics,” fixing several issues and ensuring that our patients leave with adequate oral health, rather than addressing the larger, often systemic issues that resulted in the state of their oral health. Although the steps within this large diagnostic process often require the formation of a multidisciplinary healthcare team comprised of different fields in healthcare unique to each patient, this idea is often overlooked. Our case report examines unique and surprising oral health findings that prompted the formation of such a team. Our role as a valued member of the healthcare team should be of paramount importance to our practice, and this case discusses a patient whose health required such. The conversation between physician and dentist is of continued importance and in this case one will be able to identify how systemic health is ultimately preserved and improved in this conversation.

Published: January 2022

After allogeneic hematopoietic stem‐cell transplantation (alloHSCT), the chimerism assay is used to monitor cell engraftment and quantify the respective proportions of donor/recipient cells in blood or bone‐marrow samples. Here, we aimed to better assess the utility of determining CD3+ cell chimerism within the first 6 months post alloHSCT. One hundred and thirty five patients diagnosed with acute myeloid leukemia were enrolled in this study. We observed significantly lower overall survival and relapse free survival for patients without full donor chimerism (<95%, <98%, <99%) in whole blood at Day 30, as well as at Day 90 after alloHSCT, than for patients with full donor chimerism. This outcome was not observed when assessing selected CD3+ cells. However, at Day 90, patients with discordant whole blood versus selected CD3+ cell chimerism showed both significantly lower overall survival and relapse free survival, giving an interest to assess selected cells chimerism.
Spatialising happiness economics: Global metrics, urban politics, and embodied technologies
Authors: Pykett Jessica
Published: January 2022

Happiness has become a high‐profile goal for national governments, city authorities, and technology developers finding new ways to map and measure emotions through happiness economics, urban management, and digital emotion‐sensing. This paper advances critical geographical analysis of the neglected rationales, mechanisms, and implications of promoting the emotion of happiness. Researchers, policy‐makers, and publics alike are intrigued and troubled by how a growing concern with mapping and monitoring human happiness can co‐occur with increasing levels of social inequality, human suffering, anxiety, and sadness. The paper outlines the intersection between three key trajectories (economisation, spatialisation, and technologisation) in order to demonstrate how particular assumptions about space, time, scale, and subjectivity are implied in the framing of happiness as an objective scientific construct to be measured, and as a problem of government. These trajectories combine to create what I term a new spatial science of emotions, which is yet to be defined, empirically documented, and critically analysed. It considers what kind of economic futures and contested knowledge practices are laid out by this new spatial science of emotions. By bringing together insights from critical economic geographies of neuroscientific and behavioural forms of governance, geographies of well‐being, and social theories of embodied technologies, the paper challenges researchers to shift attention from subjective well‐being to public well‐being.
Barriers and Facilitators to Help-Seeking for Mental Health Difficulties Among Professional Jockeys in Ireland
Authors: King Lewis , Cullen SarahJane , McArdle Jean , McGoldrick Adrian , Pugh Jennifer , Warrington Giles , Losty Ciara
Published: January 2022

A large proportion of jockeys report symptoms associated with mental health difficulties (MHDs), yet most do not seek help from professional mental health support services. Due to the paucity of literature in this field, this study sought to explore jockeys’ barriers to, and facilitators of, help-seeking for MHDs. Twelve jockeys participated in semistructured interviews, subsequently analyzed via reflexive thematic analysis. Barriers to help-seeking included the negative perceptions of others (stigma and career implications), cultural norms (masculinity and self-reliance), and low mental health literacy (not knowing where to seek help, minimization of MHDs, negative perceptions of treatment, and recognizing symptoms). Facilitators to help-seeking included education (exposure to psychological support at a younger age), social support (from professionals, jockeys, family, and friends), and media campaigns (high-profile disclosures from jockeys). Findings are consistent with barrier and facilitator studies among general and athletic populations. Applied recommendations and future research considerations are presented throughout the manuscript.
Extending spin market models to realistic scenarios
Authors: Borrasca Neto R. , Becker B. J. , Da Cunha C. R.
Published: January 2022

We study an extension of the Bornholdt spin-market model using configurable network topology. The distribution of returns was studied using the probability plot correlation coefficient and indicates three different behaviors for the tails of the distribution of returns. The price volatility was studied by fitting the magnetization with a Wiener process and a power-law behavior was found for the volatility as a function of the levels of randomness and connectivity of the network. Both parameters have opposing effects on the risk as inferred from the Shannon entropy of the magnetization. Also, we show that trading can spatially auto-organize depending on the conditions of the control space. Finally, we show that there is a range of values of the control space that renders a model that reproduces real-market data.

Hamiltonian analysis of ModMax nonlinear electrodynamics in the first-order formalism
Authors: Escobar C. A. , Linares Román , Tlatelpa-Mascote B.
Published: January 2022

In this work, we study the so-called ModMax nonlinear electrodynamics, which is a novel model designed to preserve duality rotations and conformal transformations, such as the Maxwell’s equations do. This model allows to study diverse gravitational phenomena when it is coupled to General Relativity, in particular charged black holes and gravitational waves. In this work, we focus in the dynamics and Hamiltonian analysis of the model. Specifically, we analyze the propagation of the discontinuities of the field and obtain the corresponding dispersion relations. To perform the Hamiltonian analysis we adopt the first-order formalism develop by Plebański and follow the Dirac method for theories with constraints. We derive the effective Hamiltonian, classify all the constraints and identify the degrees of freedom. We prove that the effective Hamiltonian is strictly bounded from below and investigate the existence of nontrivial minima.

Authors: Alhaidari A. D. , Assi I. A. , Mebirouk A.
Published: January 2022

We use the “tridiagonal representation approach” to solve the time-independent Schrödinger equation for the bound states of generalized versions of the trigono-metric and hyperbolic Pöschl–Teller potentials. These new solvable potentials do not belong to the conventional class of exactly solvable problems. The solutions are finite series of square integrable functions written in terms of the Jacobi polynomial.

Published: January 2022

Rare decays of hyperons involving di-neutrinos in the final state [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] in the Standard Model and beyond are studied. It is claimed that the branching ratios (Brs) calculated in this work are larger than the previously calculated values. For the search of NP the nonstandard neutrino interactions (NSI) are explored and constrains on NSI free parameters [Formula: see text] are found. Stringent bounds on [Formula: see text] of [Formula: see text] are obtained. It is shown that Brs could be closed to BES-III, if the constraints are [Formula: see text]. We predict that these reactions with the current value of parameter of [Formula: see text] will be in sensitivity of BES-III. To check the validity of our approach we also calculate Brs of these reactions by using 331 model and finding them consistent with previously available values of the same model.
THE IMPACT OF SOCIAL CAPITAL ON OPEN INNOVATION: THE TUNISIAN SMEs CASE
Authors: OUECHTATI SANA , MASMOUDI KAOUTHER KORBI , SLIM CHOKRI
Published: January 2022

Given that few studies have focused on the relationship between social capital, open innovation and firm performance, particularly in small- and medium-sized enterprises (SMEs), we decided to extend this line of research. Thus, we tried to focus on social capital as a key element of informal cultural norms and to study its impact on open innovation in these firms and consequently on their performance. Through a review of the literature, we were able to develop the existing relationships between these three concepts and design our theoretical model. In accordance with a positivist posture, we adopted a hypothetical-deductive approach and a quantitative empirical validation method. In order to test our conceptual model and to analyse the results of the study carried out with 67 Tunisian SMEs of the mechanical and metallurgical industries, we used the Structural Equations Method and the Neural Networks Method. The results of this research indicate that social capital significantly influences open innovation which in turn positively influences the performance of SMEs. Specifically, this study contributes to resource theory and social capital theory by first confirming that intangible resources and capabilities, associated with social capital and open innovation are valuable to SME performance. In addition to the theoretical implications, the results of this study also provide important guidance to practitioners regarding strategic direction, in that SMEs should deliberately use their limited administrative capabilities and intangible resources to support business performance. As SMEs play an important role in building, maintaining, and evolving innovation ecosystems and contribute significantly to a country’s economic growth, our research can offer significant policy implications for Tunisian SMEs to improve their innovation performance through OI strategies.

Published: January 2022

At these times, internet of things (IoT) technologies have become ubiquitous in the healthcare sector. Because of the increasing needs of IoT, massive quantity of patient data is being gathered and is utilized for diagnostic purposes. The recent developments of artificial intelligence (AI) and deep learning (DL) models are commonly employed to accurately identify the diseases in real-time scenarios. Despite the benefits, security, energy constraining, insufficient training data are the major issues which need to be resolved in the IoT enabled medical field. To accomplish the security, blockchain technology is recently developed which is a decentralized architecture that is widely utilized. With this motivation, this paper introduces a new blockchain with DL enabled secure medical data transmission and diagnosis (BDL-SMDTD) model. The goal of the BDL-SMDTD model is to securely transmit the medical images and diagnose the disease with maximum detection rate. The BDL-SMDTD model incorporates different stages of operations such as image acquisition, encryption, blockchain, and diagnostic process. Primarily, moth flame optimization (MFO) with elliptic curve cryptography (ECC), called MFO-ECC technique is used for the image encryption process where the optimal keys of ECC are generated using MFO algorithm. Besides, blockchain technology is utilized to store the encrypted images. Then, the diagnostic process involves histogram-based segmentation, Inception with ResNet-v2-based feature extraction, and support vector machine (SVM)-based classification. The experimental performance of the presented BDL-SMDTD technique has been validated using benchmark medical images and the resultant values highlighted the improved performance of the BDL-SMDTD technique. The proposed BDL-SMDTD model accomplished maximum classification performance with sensitivity of 96.94%, specificity of 98.36%, and accuracy of 95.29%, whereas the feature extraction is performed based on ResNet-v2

The global standards in the field of industrial automation are maintained in industries by completely digitizing their manufacturing process with industry 4.0 standard. Internet of Things (IoT) enables the conservation of cultural heritage with proper assistance on data management on the data collected from the sensors. However, energy efficient conservation is required to monitor the IoT sensors in order to deal with building a better infrastructure. In this paper, we develop a bio-inspired algorithm which can automate the entire furnace monitoring and controlling system in order to eliminate the human intervention involved in the physical process. The algorithm is blended as a web-based remote application for the better control of the tasks involved, energy utilized, and its subsequent log-report maintenance. The entire system employs Wi-Fi communication for data transfer from device to cloud where the stored data including temperature log, forth coming schedule, and process graphic are maintained by the proposed algorithm to predict the machine failure at an earlier stage. The real-time prototype system is supported by a heat treatment process that is completely automated using IoT to monitor and maintain the temperature during the production of metal casting process.
Ecological Security Evaluation for Marine Ranching Based on the PLTS/ANP Method: A Case Study of Rongcheng
Authors: Du Yuan-Wei , Song Qiong
Published: January 2022

The evaluation index system of ecological security of marine ranching (MRES) is based on the assumption that there is independence among evaluation indexes in the existing studies, which ignores the complex interactive paths of marine ranching as an artificial ecosystem. In this study, the MRES evaluation network model that includes interdependent relationships is established based on the Driver‐Pressure‐State‐Impact‐Response model and the analytic network process method. Then, the probabilistic linguistic term sets and analytic network process methods are used to calculate the weights of the evaluation indexes of MRES. The overall evaluation value and the contribution rate of clusters are consequently defined and analyzed to reflect the performance of MRES. Finally, a case study is carried out for evaluating the MRES of marine ranches in Rongcheng by means of the proposed method. The conclusions are summarized as follows: (1) The weights of clusters are ranked as Responses > Impact > Driver > State > Pressure, and “scientific management of fishery resources” is the most important index; (2) the MRES performance of marine ranches in the city of Rongcheng is at the medium security grade on the whole, and all 11 samples are driven by the response.

Published: January 2022

We report a heterojunction photocatalyst by coupling CdS with Bi12O17Cl2 via a facile thermal annealing process. Such heterostructure can promote the charge separation between CdS and Bi12O17Cl2, thereby leading to a considerable improvement on the performance for CO2 reduction into valuable CH4 and phenol conversion under visible light exposure. The CdS/Bi12O17Cl2 heterojunction with mass ratio of 1 : 1 (50% CdS/Bi12O17Cl2) shows the highest CH4 production rate (1.28 μmol·h-1·g-1), which is as 9.8 and 5.8 times as the CH4 generation rate of pure Bi12O17Cl2 and CdS (0.13 and 0.22 μmol·h-1·g-1), respectively. Also, the 50% CdS/Bi12O17Cl2 sample shows the highest activity of phenol conversion with a conversion ratio of 92%, which is as 2.2 times and 1.9 times as the conversion ratio of pristine Bi12O17Cl2 (41%) and CdS (48%), respectively. The present study demonstrates the great potential of the CdS/Bi12O17Cl2 heterojunction for efficient charge separation towards increased photocatalytic CH4 production and phenol conversion.

Nowadays, energy storage system is utilized in many countries for energy planning in the future. The changes in solar radiation lead to the overproduction of electricity in a solar photovoltaic generator. A hybrid energy storage system would play an important role in enhancing the reliability of power generation using the solar system. The microgrid is the indispensable infrastructure of the smart grid in photovoltaic systems. In this paper, the energy storage system within the microgrid of the PV system is analysed. The storage system configuration and topologies of the microgrid are analysed with power electronic interference, control scheme, and optimization of the renewable source and energy storage system. A general sizing technique for HESS in a PV system based on pinch analysis and design space. The size of HESS scales that connect generator ratings to storage capacity is created by utilizing the pinch analysis on load and resource data. The design space is a feasible combination of a short-, long-, and medium-sized energy storage system in a PV generator.

With the rapid development of network technology and the rapid growth of all kinds of online information resources, a large number of Chinese language and literature resources have emerged on the Internet. Online Chinese language and literature resources are becoming more and more important sources for people to obtain important information. However, existing search engines tend to provide a lot of irrelevant content when searching for information. Therefore, how to quickly and effectively obtain useful resource information and classify Chinese language and literature resources from a large number of information resources is the focus of this paper. This article mainly aims at the current development situation, by consulting a large amount of data, understanding the research status of improved SVM algorithm at home and abroad, showing the idea and advantages of SVM through the algorithm and experimental process, and further improving the SVM algorithm. The improved SVM proposed in this paper greatly improves the efficiency of classification and facilitates the rapid search of information with high matching degree among various online resources of Chinese language and literature.
Step-by-Step Penalized Blind Kriging Methods for Surrogate Modeling
Authors: Feng Ziheng , Li Min , Wang Xiao , Zhao Jianxin , Li Xinmin
Published: January 2022

When building a surrogate model, it is important to identify a proper mean function for the kriging model. The commonly used variable selection method is the penalized blind kriging (PBK) method. But this method could lead to a low time efficiency, which is not suitable for experiments with time-sensitive data. In this paper, we propose three step-by-step approaches for constructing an appropriate mean function to improve the prediction accuracy and time efficiency of the PBK method. Several functions and two engineering examples are used to prove the effectiveness of the proposed methods. From simulation results, we can see that Method 1 (M1) and Method 2 (M2) have been significantly improved in both the prediction accuracy and the time efficiency compared with PBK. Especially, in the Test function, compared with the traditional PBK method, the prediction accuracy of M2 is improved by

Background and Objective. Knee osteoarthritis is a serious epidemiological problem that causes severe pain and impairs abilities. We investigated the effects of adductor canal blockade (ACB) on chronic osteoarthritis knee pain, motor function, and mobility. Methods. Seventy‐seven patients with chronic knee osteoarthritis pain received ultrasound‐guided ACB with 14 ml 0.25% levobupivacaine and 100 mcg clonidine. At baseline and 1 month after the blockade, we assessed maximal and minimal pain intensity in the knee using a numeric rating scale (NRS) and the Knee Injury and Osteoarthritis Outcome Score (KOOS). The range of motion in extension and flexion (ROMext and ROMflex) and quadriceps muscle strength of both knees (QS), Timed Up and Go Test (TUG), and 30‐Second Chair Stand Test (30CST) results were determined at baseline, 1 hour, 1 week, and 1 month after the blockade. Results. ACB with levobupivacaine and clonidine appeared to decrease pain severity (NRSmax 8.13 to 4.2, p < 0.001 and NRSmin 3.32 to 1.40, p < 0.001). Similarly, knee ROMext decreased from 3.90 preintervention to 2.89 postintervention at 1 month, p < 0.001; ROMflex decreased from 5.70 to 3.29, p < 0.001; TUG time decreased from 3.22 to 2.93, <0.001; QS increased from 18.43 to 22.77, p < 0.001; CST increased from 8.23 to 10.74, p < 0.001. The KOOS for pain (36.40 to 58.34), symptoms (52.55 to 64.32), activities of daily living functions (ADLs, 36.36 to 60.77), and quality of life (QoL, 17.87 to 30.97) also increased, all p < 0.001. Conclusion. ACB appeared to decrease pain and increase ambulation. If our preliminary results are reproducible in a planned randomized controlled trial, ACB could be a useful adjunctive pain therapy in patients with disabling pain due to knee OA.

A simple hydrothermal method is developed for the synthesis of high‐quality type II core‐shell CdSe/CdTe quantum dots (QDs). The XRD results reveal the formation of mixed phases of CdSe and CdTe with a grain size of 12.6 nm. SEM morphology confirms the uniformly distributed nanoscale CdSe/CdTe with no agglomeration. EDX confirms the elemental presence of Cd, Se, and Te in the compound. TEM results suggest that the size of spherical CdSe/CdTe core‐shell QDs is in the range of 8~10 nm. Significant results of the SAED pattern confirm the core and shell components as CdSe and CdTe, respectively. The correlation between the synthesis procedures and the corresponding structures of the core‐shell CdSe/CdTe QDs is discussed. The demonstrated monodispersed lattice structure of core‐shell CdSe/CdTe QDs has excellent PL emission properties at λemi ~ 585 nm which is suitable for photovoltaic applications. The UV‐Vis absorption bands at 455 nm and 560 nm confirm exciton emission due to the type II matrix of CdSe/CdTe QDs.

The ever-increasing water stress and availability of fresh drinking water are becoming a major challenge in rural and urban communities. The current high-end and large-scale technologies are becoming way more expensive and not friendly to the environment. In this regard, solar still is becoming a prominent and promising future technology due to its environment-friendly nature, less maintenance and operational costs, and simple design. The technological challenge regarding solar still is its low distillate yield. In this study, an attempt has been made to investigate the effect of tin oxide (SnO2) on the absorption surface of solar still towards improvement in sunlight absorption, which would lead to high distillate production rates. Various concentrations of SnO2, i.e., 0.5wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt%, 10 wt%, 15 wt%, and 20 wt%, have been mixed in black and applied on the absorber plate to further optimize the suitable concentration. The experiments have been performed in both indoor (simulated) and outdoor conditions. An increase in surface temperature of absorber plate has been observed with increasing concentration of SnO2 under both the indoor and outdoor conditions, which is due to high solar spectrum absorption properties of SnO2 in the ultraviolet (UV) and near to far-infrared (IR) regions. The highest surface temperature of 101.61°C has been observed for specimens containing 15 wt% SnO2 in black paint under indoor conditions at 1000W/m2 irradiation levels, which is 53.67% higher compared to bare aluminum plate and 16.91% higher compared to only black paint coated aluminum plate. On the other hand, the maximum temperature of 74.96°C has been recorded for the identical specimens containing 15 wt% SnO2 under uncontrolled outdoor conditions. The recorded temperature is 47.96% higher than the bare aluminum plate and 14.88% higher than the black paint-coated aluminum plate. The difference of maximum temperatures under indoor and outdoor conditions is due to uncontrolled outdoor conditions and convective losses.
Fractional Sobolev Space on Time Scales and Its Application to a Fractional Boundary Value Problem on Time Scales
Authors: Hu Xing , Li Yongkun
Published: January 2022

By the concept of fractional derivative of Riemann-Liouville on time scales, we first introduce fractional Sobolev spaces, characterize them, define weak fractional derivatives, and show that they coincide with the Riemann-Liouville ones on time scales. Then, we prove equivalence of some norms in the introduced spaces and derive their completeness, reflexivity, separability, and some imbeddings. Finally, as an application, by constructing an appropriate variational setting, using fibering mapping and Nehari manifolds, the existence of weak solutions for a class of fractional boundary value problems on time scales is studied, and a result of the existence of weak solutions for this problem is obtained.
A New Method for Predicting Residual Strength of Rock in Water Diversion Tunnel Using Drilling Process Monitoring
Authors: Gao Wanfei
Published: January 2022

The peak and residual strengths of rock materials are important parameters for the stability evaluation of rock engineering, especially water diversion tunnels. A friction-strengthening model based on Hoek–Brown model is proposed to determine peak and residual strength of rock. The proposed model parameter, contact friction coefficient of rock, controls the nonlinearity of the peak strength and residual strength. With a great amount of data from publications examined, the relationship between the friction coefficient and the parameters in the Hoek–Brown model is studied. A new field method using drilling process monitoring was proposed to predict the peak strength and residual strength. The results show that the predicted strength for four types of rock is in good agreement with those of the standard tests in laboratory. Their errors are within the error range of 15% compared to the results from the tested results in laboratory. Although the proposed model is empirical, the parameters in the proposed model have clear physical meaning, and it can successfully predict the peak strength and residual strength of hard rock, medium rock, and weak rock using drilling process monitoring in the field. This practical method should have a great potential for field application in rock engineering.
The Role of Oxidative Stress in the Pathogenesis of Vitiligo: A Culprit for Melanocyte Death
Authors: Xuan Yijie , Yang Yiwen , Xiang Leihong , Zhang Chengfeng
Published: January 2022

Vitiligo is a common chronic acquired pigmentation disorder characterized by loss of pigmentation. Among various hypotheses proposed for the pathogenesis of vitiligo, oxidative stress-induced immune response that ultimately leads to melanocyte death remains most widely accepted. Oxidative stress which causes elevated levels of reactive oxygen species (ROS) can lead to dysfunction of molecules and organelles, triggering further immune response, and ultimately melanocyte death. In recent years, a variety of cell death modes have been studied, including apoptosis, autophagy and autophagic cell death, ferroptosis, and other novel modes of death, which will be discussed in this review in detail. Oxidative stress is also strongly linked to these modes of death. Under oxidative stress, ROS could induce autophagy by activating the Nrf2 antioxidant pathway of melanocytes. However, persistent stimulation of ROS might eventually lead to excessive activation of Nrf2 antioxidant pathway, which in turn will inactivate autophagy. Moreover, ferroptosis may be triggered by oxidative-related transcriptional production, including ARE, the positive feedback loop related to p62, and the reduced activity and expression of GPX4. Therefore, it is reasonable to infer that these modes of death are involved in the oxidative stress response, and that oxidative stress also acts as an initiator for various modes of death through some complex mechanisms. In this study, we aim to summarize the role of oxidative stress in vitiligo and discuss the corresponding mechanisms of interaction between various modes of cell death and oxidative stress. These findings may provide new ideas for exploring the pathogenesis and potential therapeutic targets of vitiligo.
