Published: August 2022

Seismic noise suppression plays an important role in seismic data processing and interpretation. Aiming at remedying the problem of low quality of seismic data acquired by a seismometer, a novel denoising method based on wavelet maximum modulus and an adaptive threshold is designed. This adaptive wavelet maximum modulus (ATWMM) seismic signal noise reduction method is using the opposite polarity of the Lipschitz index with seismic signal and noise to extract the seismic signal of original data. Setting adaptive thresholding function related to wavelet decomposition scale to solve the problem of effective signal losing on a small decomposition scale. The experimental results show that the ATWMM method can extract more seismic signal from the noisy seismic data. Using RMSE and SNR evaluation, the synthetic Ricker seismic dataset experimental results show that the indexes are 0.0502 and 20.1617 dB. Compared with the wavelet modulus maximum (WMM) method, it has a 25.7% reduction and 14.6% increase. The real-field seismic data came from the JZW51 seismic monitoring station in China experimental results indicate that the proposed ATWMM method is effective in seismic signal denoising with SNR above 30.1855 dB of approximately 15.8% enhancement compared with the WMM method, that has improvement for quality of seismic data.

Authors: Guo Kaimeng , Gu Yinan
Published: August 2022

With the emergence of new tourism trends such as popularized and individualized tourism, the traditional development model can no longer meet the development requirements of the new era. Therefore, the construction of tourism informatization is imperative. This work aims to enhance the promotion of tourism resources in Zhejiang Province and explore the effective promotion forms and strategies of tourism resources in Zhejiang network media. The construction of smart tourism city (STC) is taken as the research object. First, the evaluation index system and evaluation model of the construction level of STC are constructed. Besides, an empirical evaluation is conducted with the pilot project of smart tourism city construction determined by the National Tourism Administration as a case. Then, the concept of strength, weakness, opportunity, and threat (SWOT) is used to analyze the advantages, disadvantages, opportunities, and threats of Zhoushan Town’s tourism development. Finally, the model proposed here is tested. The results show that the comprehensive level of STC in 18 cities is quite different. The current average level of STC in China is 0.2791. Except for the support level of smart tourism environment that is lower than Suzhou, the rest levels of Beijing are in the first place, and the comprehensive level of STC construction is in the first place. The comprehensive level of STC construction in Suzhou ranks second, with an average level of 0.1521. Nevertheless, there is a big gap between Suzhou with Beijing. The overall evaluation satisfaction of Zhoushan Town’s tourism is in a moderate state. The analysis results of the SWOT intelligent model demonstrate that Zhoushan Town tourism should choose a growth marketing strategy. The research reported here provides a particular reference for realizing the seamless connection between the intelligent cultural tourism industry and consumers.
[Retracted] NORAD Promotes the Viability, Migration, and Phenotypic Switch of Human Vascular Smooth Muscle Cells during Aortic Dissection via LIN28B‐Mediated TGF‐β Promotion and Subsequent Enhanced Glycolysis
Authors: Xia Shi-bo , Tian Zhuang-bo , Zhang Wenbo , Zhang Hao
Published: August 2022

Glucose metabolism reprogramming is an important reason for the functional remodeling, growth, and migration of vascular smooth muscle cells (VSMCs). It is also an important basis for the occurrence and development of aortic dissection (AD), but the specific regulatory factors are not clear. Noncoding RNA activated by DNA damage (NORAD) is dysfunctional in many diseases, but the role of NORAD in AD etiology is unclear. We first established a vascular remodeling cell model of AD, and the expression of NORAD in VSMCs was significantly increased. Functional experiments showed that inhibition of NORAD could downregulate the proliferation and migration of VSMCs. Meanwhile, silencing NORAD could also inhibit the flux of glycolysis, suggesting that NORAD may aggravate AD by promoting glycolysis. In addition, mechanism studies have shown that NORAD can exert VSMCs‐regulating function by recruiting LIN28B to bind to TGF‐β mRNA, which subsequently facilitates the expression of TGF‐β1 (transforming growth factor β1). The recovery experiment also showed that overexpression of TGF‐β could reverse the inhibitory effect of NORAD knockdown on VSMCs in terms of proliferation, migration, and glycolysis. Collectively, these results indicated that the NORAD/LIN28B/TGF‐β axis promoted cell proliferation and migration through regulating aerobic glycolysis in VSMCs. Therefore, NORAD may regulate the occurrence of AD by affecting the reprogramming of glucose metabolism, and NORAD can be recognized as a good target for VSMC phenotypic intervention and AD treatment.

Published: August 2022

Background. Since transcatheter aortic valve replacement (TAVR) first became approved for inoperable patients followed by high, intermediate-, and low-risk patients, referrals to TAVR centers have rapidly increased. The purpose of this study was to investigate referral patterns to a large academic TAVR center in the state of North Carolina and evaluate differences between externally and internally referred patients. Methods. Data for all patients who underwent TAVR at our institution between November 2014 and March 2020 were pulled from the Transcatheter Valve Therapy Registry. The electronic medical record was used to determine the referral source. The descriptive statistical analysis was performed using Excel (Microsoft, Redmond, Washington). Results. 491 patients underwent TAVR at our institution between November 2014 and March 2020. Half of the patients were referred by a cardiologist within the same health system (N = 250, 50.9%). Other referral sources included a cardiologist external to the health system (N = 210, N = 42.8%) and a surgeon or proceduralist (such as urologist, surgeon, or gastroenterologist) during the workup for another procedure (N = 26, 5.3%). Over time, there was a trend toward an increasing proportion of patients referred by a cardiologist external to our system, but this trend did not reach statistical significance (20.0% in 2014, 29.2% in 2015, 30.7% in 2016, 53.0% in 2017, 36% in 2018, 48.4% in 2019, and 56.8% in 2020,

using the Mann–Kendall trend test). Externally referred patients were less likely to have private insurance and were more likely to have a reduced ejection fraction and had a higher mean gradient across the valve. Postprocedure, externally referred patients were more likely to have the procedure under moderate sedation and less likely to be discharged home. Conclusions. This study presents the referral pattern to a large TAVR center in North Carolina. Over time, there was an increase in external referrals suggesting that TAVR is increasingly adopted as an important component of the management of aortic valve stenosis. Internally and externally referred patients have differences in baseline demographic and clinical characteristics which may have an impact on clinical outcomes.

Authors: Nireeksha Nireeksha , Hegde Mithra N. , Shetty Shilpa S. , Kumari Suchetha N.
Published: August 2022

The prevalence of dental caries in individuals who practice good oral hygiene increasingly indicates that other etiological factors, such as genetic factors, may be responsible for occurrence of caries, and its prevalence in younger individuals, such as adolescents, is an early manifestation of their genetic makeup. Therefore, there is a need to investigate the correlation of various genetic factors with the occurrence of dental caries in populations. Thus, this study assessed the relationship between single nucleotide polymorphism (rs2228570) in the vitamin D receptor gene and dental caries susceptibility. After obtaining ethical approval (NU/CEC/2020/0339), 377 adults, aged 18–40 years, were included in this study. Among the participants consenting to participate, salivary samples were collected, and an oral examination was conducted using the World Health Care Oral Health Survey Format 2013. The DMFT and PUFA index scores were recorded along with basic demographic details. The subjects were categorized as caries-free (controls, DMFT = 0) and caries-active (cases). The case group was further divided into the high-risk group (DMFT ≤ 10), moderate-risk group (DMFT = 4–9), and low-risk group (DMFT = 1–3). Saliva samples were used for vitamin D level analysis and DNA isolation. Polymerase chain reaction-based restriction fragment length polymorphism analysis using Fok1 digestion was performed on the isolated DNA. Salivary vitamin D levels were markedly higher in the caries-free group than in the caries-active group (

p

). The T allele of rs2228570 was significantly associated with having active caries, while the C allele was associated with being caries-free. Individuals with the rs2228570 TC genotype had 2.814-fold increased likelihood, and individuals with the TT genotype had 3.116- fold increased likelihood of being caries-active. This finding is important in terms of patient counselling, as well as possibly in terms of prevention and treatment of caries.

Authors: Peng Zhiqiang , Xiong Jianping , Dong Hanzhi
Published: August 2022

Objective. Alproic acid (VPA) is a clinic antiepileptic drug. Antitumor role of VPA has been studied. The aim of this study was to clarify the treatment effect and potential mechanism of VPA on peripheral T cell lymphomas (PTCLs). Materials and Methods. Hut 78 cells were obtained from the Shanghai Cell Bank, Chinese Academy of Sciences, and randomly divided into six groups: control, VPA (8 mM), empty vector (NC), miR-3196 mimics, miR-3196 inhibitor, and VPA + miR-3196 mimics groups. CCK-8 assay was performed to clarify the regulative role of VPA on cell proliferation. Flow cytometry was applied to determine the apoptotic rate and ROS levels. miR-3196 was tested by RT-qPCR. Western blot was used to test the level of p-PI3K and p-AKT. Biochemical experiments were used to detect changes in the content of ATP, lactate level, and glucose content. Electron microscopy was used to show the structure of mitochondria in Hut 78 cells. Results. VPA greatly promoted the expression of miR-3196 and inhibited cell proliferation in a dose-dependent manner. Compared with the NC group, the cell apoptosis rate, Bax and cleaved-caspase-3 expression, lactate level, ROS expression, and glucose content in the VPA group were significantly increased (

P
<
0.05

), and cell proliferation, ATP production, and the expression of Bcl-2, p-PI3K and p-AKT was decreased significantly (

P
<
0.05

). The role of mir-3196 mimics is similar to VPA. While, the miR-3196 inhibitor had the opposite effect to VPA and mimics. The combination of VPA and miR-3196 mimics has the most obvious effect. Conclusion. VPA can inhibit the proliferation of Hut 78 cells and promote cell apoptosis and the structure and dysfunction of mitochondria by regulating the activity of the PI3K/AKT pathway.

Finasteride is considered the drug of choice for androgenic alopecia and benign prostate hyperplasia. The aim of the study was to formulate nanodrug carriers of finasteride with enhanced retentive properties in the skin. The finasteride was formulated as solid lipid nanoparticles that were decorated with different concentrations of chitosan for improved retentive properties. Solid lipid nanoparticles (SLNs) were synthesized by “high‐speed homogenization technique” using stearic acid as a solid lipid while PEG‐6000 and Tween‐80 were used as surfactants. The SLNs were evaluated for particle size, polydispersity index (PDI), zeta potential, drug entrapment efficiency, and drug release behavior. The mean particle size of SLNs was in the range of 10.10 nm to 144.2 nm. The PDI ranged from 0.244 to 0.412 while zeta potential was in the range of 8.9 mV to 62.6 mV. The drug entrapment efficiency in chitosan undecorated formulations was 48.3% while an increase in drug entrapment was observed in chitosan‐decorated formulations (51.1% to 62%). The in vitro drug release studies of SLNs showed an extended drug release for 24 hours after 4 hours of initial burst release. The extended drug release was observed in chitosan‐coated SLNs in comparison with uncoated nanoparticles. The permeation and retention study revealed higher retention of drug in the skin and low permeation with chitosan‐decorated SLNs that ranged from 39.4 μg/cm2 to 13.2 μg/cm2. TEM images depicted spherical shape of SLNs. The stability study confirmed stable formulations in temperature range of 5°C and 40°C for three months. It is concluded from this study that the SLNs of finasteride were successfully formulated and chitosan decoration enhanced the drug retention in the skin layers. Therefore, these formulations could be used in androgenic alopecia and benign prostate hyperplasia to avoid the side effects, drug degradation, and prolonged use of drug with conventional oral therapy.

Published: August 2022

Autophagy plays a key role in ischemic stroke, but its mechanism remains to be elucidated. In order to explore the effect of autophagy on ischemic stroke, bibliometric analysis and view tools are used to identify the directions of the global research trends and construct full view of the autophagy in ischemic stroke from 2006 to 2022. The research hotspots of autophagy related to ischemic stroke are visually analyzed and generated various visual maps to display publications, authors, sources, countries, organizations, and keywords. By bibliometric analysis, it can be seen that the investigations of autophagy in ischemic stroke is focused on both brain injury and neuroprotection. The impact of a variety of inflammatory factors and signaling pathways on autophagy following an ischemic stroke is also studied. Autophagy plays an important role in all phases of ischemic stroke. It is of great significance to guide the development of treatment plans for ischemic stroke.
Light Gradient Boosting Machine-Based Link Quality Prediction for Wireless Sensor Networks
Authors: Liu Linlan , Niu Mingxiao , Zhang Chao , Shu Jian
Published: August 2022

Link quality prediction is a fundamental component of the wireless network protocols and is essential for routing protocols in wireless sensor networks (WSNs). Effective link quality prediction can select high-quality links for communication and improve the reliability of data transmission. In order to improve the accuracy of the link quality prediction model and reduce the model complexity, the link quality prediction model based on the light gradient boosting machine (LightGBM-LQP) is proposed in this paper. Specifically, agglomerative hierarchical clustering and manual division are combined to grade the link quality and obtain the labels of samples. Then, light gradient boosting machine (LightGBM) classification algorithm and Focal Loss are used to estimate the link quality grades. In order to reduce the impact of data imbalance, Borderline-SMOTE is employed to oversample the minority link quality samples. Finally, LightGBM-LQP predicts link quality grade at the next moment with historical link quality information. The experimental results on data collected from a real-world WSNs show that the proposed model has better prediction accuracy and shorter predicting time compared to related models.
GPBFT: A Practical Byzantine Fault-Tolerant Consensus Algorithm Based on Dual Administrator Short Group Signatures
Authors: Yu Xiaosheng , Qin Jie , Chen Peng
Published: August 2022

The practical Byzantine fault-tolerant consensus algorithm reduces the operational complexity of Byzantine protocols from an exponential level to a polynomial level, which makes it possible to apply Byzantine protocols in distributed systems. However, it still has some problems, such as high communication overhead, low security, poor scalability, and difficulty in tracking. In this article, we propose a Byzantine fault-tolerant consensus algorithm based on dual administrator short group signatures (GPBFT). Firstly, the certification authority chooses the master node and group administrators based on the credit value. The group administrators organize the nodes into a group, and the members generate the signatures by applying the short group signatures scheme, in which any group member can represent the group during the GroupSign phase. Additionally, the GPBFT algorithm adds the Trace phase. According to member and client authentication information, the group administrator can track the true identity of the malicious node, identify the malicious node, and revoke it. The experimental results show that compared with the PBFT algorithm, the GPBFT algorithm can reduce the network communication overhead, reduce the consensus delay, and greatly improve the security and stability of the system. The algorithm can effectively manage member nodes and enable the tracking of identified malicious nodes while maintaining anonymity in terms of node tracking.

Published: August 2022

Epidemiological studies have shown that exposure to beneficial microorganisms can reduce the risk of asthma, but the clinical use of live probiotics is controversial due to the risk of infection. As heat-killed probiotics can also exhibit immunomodulatory activity, this study is aimed at investigating whether heat-killed Clostridium butyricum (HKCB) CGMCC0313-1 could reduce allergic airway inflammation in an ovalbumin-induced mouse model. Mice received aerosol inhalation of HKCB, oral administration of HKCB, or oral administration of live Clostridium butyricum (CB) during sensitization. Bronchoalveolar lavage fluid cell number, histology, and levels of the cytokines interferon-gamma and IL-4, the autophagy-related proteins LC3B, Beclin1, and p62, and members of the nuclear factor kappa B (NF-κB)/NLRP3 inflammasome signaling pathway were examined. Our results demonstrated that aerosol inhalation of HKCB, oral HKCB administration, and oral live CB administration alleviated allergic airway inflammation and mucus secretion in allergic mice. Aerosol inhalation of HKCB was the most effective method; it restored the Th1/Th2 balance, ameliorated autophagy, and inhibited the NF-κB/NLRP3 inflammasome signaling pathway in the lungs of allergic mice. Thus, aerosol inhalation of HKCB could be a promising strategy for the prevention or treatment of asthma.

Published: August 2022

Background. Delayed onset of muscle soreness (DOMS) and its physiological consequences influenced an individual’s adherence to an exercise routine. Objective. This study aimed to evaluate the efficacy, safety, and tolerability of TurmXTRA® 60N (WDTE60N) on DOMS compared to placebo in recreationally active healthy subjects. Methods. This randomized, double-blind, placebo-controlled parallel-group study enrolled 30 healthy and recreationally active subjects (average age: 28.23 ± 4.20 years) and randomized them to receive WDTE60N (WDTE60N group; n = 15) or placebo (placebo group; n = 15). Study treatments were initiated 29 days before the eccentric exercise and were continued for 4 days after the exercise. The primary endpoint was the change in pain intensity measured by the visual analog scale (VAS) at the end of study treatment (at 96 hours after eccentric exercise) from baseline (measured immediately after exercise). Results. The VAS score indicated that subjects from the WDTE60N group reported significantly less pain after eccentric exercise compared to the placebo group (AUC0–96h: 286.8 ± 46.7 vs. 460 ± 40.5, respectively;

p

Aim. While a patient’s nutritional status is known to generally have a role in postoperative wound healing, there is little information on its role as therapy in the multifaceted problem of diabetic foot infections (DFIs). Methods. We assessed this issue by conducting a retrospective case-control cohort study using a multivariate Cox regression model. The nutrition status of the DFI patients was assessed by professional nutritionists, who also orchestrated the nutritional intervention (counselling, composition of the intrahospital food) during hospitalization. Results. Among 1,013 DFI episodes in 586 patients (median age 67 years; 882 with osteomyelitis), 191 (19%) received a professional assessment of their nutrition accompanied by between 1 and 6 nutritional interventions. DFI cases who had professional nutritionists’ interventions had a significantly shorter hospital stay, had shorter antibiotic therapies, and tended to fewer surgical debridements. By multivariate analysis, episodes with low Nutritional Risk Status- (NRS-) Scores 1-3 were associated with significantly lower failure rates after therapy for DFI (Cox regression analysis; hazard ratio 0.2, 95% confidence interval 0.1-0.7). Conclusions. In this retrospective cohort study, DFI episodes with low NRS-Score were associated with lower rates of clinical failure after DFI treatment, while nutritional interventions improved the outcome of DFI. We need prospective interventional trials for this treatment, and these are underway.

Authors: Feng Luoyin , Chen Xin
Published: August 2022

With the continuous development of Internet technology and technological innovation, image recognition technologies such as face unlocking and face brushing payment have gradually entered daily life. However, it can not be ignored that these technologies not only bring us great convenience but also face great risks. The biological characteristics of a face image are unique, and it will be difficult to modify once it is leaked. If the image information stored in the cloud is leaked because it cannot be properly kept, users have no privacy. The encryption and recognition of face image can effectively solve this problem. Aiming at this, high-dimensional chaos Henon Map and one-dimensional chaos Logistic Map are used to generate a key to complete the encryption of the image in the transformation domain, and the capacity and complexity of the key are further enhanced. Then, combined with BP neural network to achieve face image recognition. Finally, the robustness of the proposed algorithm is verified and analyzed by conventional attacks, geometric attacks, and occlusion attacks.
Towards Ethical AI: Empirically Investigating Dimensions of AI Ethics, Trust Repair, and Performance in Human-AI Teaming
Authors: Schelble Beau G. , Lopez Jeremy , Textor Claire , Zhang Rui , McNeese Nathan J. , Pak Richard , Freeman Guo
Published: August 2022

Objective

Determining the efficacy of two trust repair strategies (apology and denial) for trust violations of an ethical nature by an autonomous teammate.

Background

While ethics in human-AI interaction is extensively studied, little research has investigated how decisions with ethical implications impact trust and performance within human-AI teams and their subsequent repair.

Method

Forty teams of two participants and one autonomous teammate completed three team missions within a synthetic task environment. The autonomous teammate made an ethical or unethical action during each mission, followed by an apology or denial. Measures of individual team trust, autonomous teammate trust, human teammate trust, perceived autonomous teammate ethicality, and team performance were taken.

Results

Teams with unethical autonomous teammates had significantly lower trust in the team and trust in the autonomous teammate. Unethical autonomous teammates were also perceived as substantially more unethical. Neither trust repair strategy effectively restored trust after an ethical violation, and autonomous teammate ethicality was not related to the team score, but unethical autonomous teammates did have shorter times.

Conclusion

Ethical violations significantly harm trust in the overall team and autonomous teammate but do not negatively impact team score. However, current trust repair strategies like apologies and denials appear ineffective in restoring trust after this type of violation.

Application

This research highlights the need to develop trust repair strategies specific to human-AI teams and trust violations of an ethical nature.
Predictors of Knowledge, Attitudes, Practices and Barriers Regarding Sepsis and Sepsis Management Among Emergency Nurses and Physicians in Palestine: A Cross-Sectional Analysis
Authors: Salameh Basma , Aboamash Ali Eyad Mahmoud
Published: August 2022

Sepsis is a widespread problem that can create clinical and economic difficulties. This study aimed to determine the knowledge, attitudes, practices, and barriers related to the sepsis and sepsis management among emergency nurses and physicians. Data was collected using a self-questionnaire completed by the participating nurses and physicians (n = 243), with a 61% response rate. The study found that both emergency nurses and physicians had poor-to-moderate levels of sepsis knowledge, with emergency physicians having better attitudes regarding sepsis and sepsis management than emergency nurses. However, moderate knowledge levels of sepsis practice and management were shown among both nurses and physicians. It is evident that for emergency nurses and physicians, the biggest barrier to providing quality care to patients with sepsis is the lack of monitoring equipment. Both nurses and physicians need consistent sepsis management information provided by continual education programs. Development of an approved protocol can improve nurses’ knowledge, attitudes, and practices.
Changing Employers’ Implicit Attitudes About the Competence of People Who Are Blind
Authors: McDonnall Michele C. , Antonelli Karla
Published: August 2022

Introduction: Long-held societal beliefs about the incompetence and dependence of people who are blind are thought to contribute to their low employment rates. This experimental study examined the impact of a meeting between a vocational rehabilitation (VR) professional and a hiring manager on these beliefs, or implicit attitudes, about the competence of people who are blind. Method: Participants were 57 hiring managers working for a financial services company in the southern United States who participated in a one-hour meeting with a VR professional. Two VR professionals, one sighted and one blind, conducted the meetings, utilizing one of two approaches, resulting in a 4 (group) × 3 (time) experimental design. Implicit attitudes were measured with the Implicit Association Test-Blind & Visually Impaired (IAT-BVI) at pre-test, post-test, and a 4-month follow-up and data were analyzed using repeated-measures ANOVA. Results: IAT-BVI scores decreased significantly following the meeting, though the size of the change was small. Type of approach and the interaction between approach and the VR professional’s vision status were not significantly associated with IAT-BVI change. Although vision status was not significantly associated with IAT-BVI change, follow-up analyses documented that participants who met with the blind VR professional had a significant decrease in IAT-BVI scores. Discussion: Hiring managers’ implicit attitudes significantly improved following a meeting with a VR professional, providing evidence that a brief interaction can decrease employers’ implicit bias regarding the competence of blind people. In addition, hiring managers who met with the blind VR professional showed significant improvement in their implicit attitudes after the meeting, with a medium-to-large effect. Implications for Practice: VR professionals should communicate with employers as much as possible about the work capabilities of individuals who are blind to help improve their implicit attitudes, and be aware that incorporating exposure to a competent blind person may result in a greater impact.
The Mandate to Provide Expanded Core Curriculum Instruction
Authors: Chase Alan Anthony
Published: August 2022

Introduction: This study examined potential legal precedent set by holdings in administrative due process hearings where instruction in the expanded core curriculum (ECC) for school-age children was decided. Methods: This study used an analogical reasoning approach. This legal research method includes examining the rule of law, presenting cases for comparison, and applying the fact pattern to predict outcomes of current or future cases. Results: The results demonstrate that the inclusion of the ECC in an Individualized Education Program (IEP) varies from state to state. Only two states have passed legislation requiring instruction in the ECC. These statutes have been referenced in case holdings. Administrative hearings from four different jurisdictions in the United States have held that the ECC must be included in the IEP to some extent.

Discussion: The ECC is a critical component of the education of students with visual impairments and must be incorporated in some form within their IEPs. Depending upon the jurisdiction, the ECC may have to be explicitly stated in the IEP, while in other locales it may have to be embedded within the IEP. In some states, specific statutes governing instruction in the ECC form the rule of law. Implications for Practitioners: School administrators and teachers of students with visual impairments should be knowledgeable of the legislation governing the ECC in their state and the legal precedents that have been created in their state. School administrators and teachers of students with visual impairments should carefully consider how the principles of a legal precedent can be applied to situations within their own communities to understand their obligations and likelihood of prevailing in any legal dispute. Finally, parents and students with visual impairments should be aware of the legal precedent created for the ECC in their state and use the dispute resolution process to inform change in their own communities as the families did in these exemplar cases.

Published: August 2022

Background:

Emotional facial expression database, used in emotion regulation studies, is a special set of pictures with high social and biological relevance. We present the AIIMS Facial Toolbox for Emotion Recognition (AFTER) database. It consists of pictures of 15 adult professional artists displaying seven facial expressions—neutral, happiness, anger, sadness, disgust, fear, and surprise.

Methods:

This cross-sectional study enrolled 15 volunteer students from a professional drama college in India (six males and nine females; mean age = 26.2 ± 1.93 years). They were instructed to pose with different emotional expressions in high and low intensity. A total of 240 pictures were captured in a brightly lit room against a common, light background. Each picture was validated independently by 19 mental health professionals and two professional teachers of dramatic art. Apart from recognition of emotional quality, ratings were done for each emotion on a 5-point Likert scale with respect to three dimensions—intensity, clarity, and genuineness. Results are discussed in terms of mean scores on all four parameters.

Results:

The percentage hit rate for all the emotions, after exclusion of contempt, was 84.3%, with the mean kappa for emotional expression being 0.68. Mean scores on intensity, clarity, and genuineness of the emotions depicted in the pictures were high.

Conclusions:

The database would be useful in the Indian context for researching facial emotion recognition. It has been validated among a group of experts and was found to have high inter-rater reliability.
Anticipation and modal power: Opening up and closing down the momentum of sociotechnical systems
Authors: Urueña Sergio
Published: August 2022

Within STS, there are three approaches to the creation and mobilization of futures: descriptive, normative, and interventive. Visions, expectations, and imaginaries are currently seen as anticipatory artifacts that close down the momentum of sociotechnical systems and, as such, are objects of critical scrutiny. At the same time, interventive techniques engaging with future representations are considered to be useful anticipatory instruments for opening up ranges of envisaged alternatives. This article reviews STS advances concerning the performativity of both de facto and interventive anticipatory practices in shaping the momentum of sociotechnical systems in light of the phenomenon of modal power: the modulation dynamics of what actors deem to be (im)plausible and/or (un)desirable. The diverse attempts of STS scholars and practitioners to understand, critique, and engage with the politics of opening up and closing down the momentum of sociotechnical systems require engaging with the creation, mobilization, and execution of modal power. The heuristics presented here are intended to be useful in framing and recognizing the political-epistemic radicality that the creation and mobilization of sociotechnical futures holds in the constitution of our sociotechnical orders as well as the role that the attribution of (im)plausibility or (un)desirability plays in such processes.
The architecture of the hybrid lab: Spacing graphene research
Authors: Yaneva Albena
Published: August 2022

Building on and renewing a long line of STS research of lab materialities, this article sheds light on a type of architecture organized around the ‘heroic agency’ of a new nanomaterial, graphene. It examines how design responds to the dynamic and multi-applicational ambitions of contemporary science. An ethnographic study of the National Graphene Institute in Manchester allows us to see how the building’s design has epistemic and social effects, how different spatial arrangements facilitate the shaping of research habits and mediate various rhythms of lab work. Key features of this hybrid lab are: first, a shifting balance between public and private places, with a prevalence of collective activities; second, its capacity to reinforce epistemically and socially the conditions of visibility, by emphasizing the work of making research practice visible; third, its distinctive way to speed up research, often by slowing down the circulation of people and things. All these features make the hybrid lab a unique spatial articulation of a new cultural order of innovation.
Charging Infrastructure and Schedule Planning for a Public Transit Network with a Mixed Fleet of Electric and Diesel Buses

Promoting battery electric buses (BEBs) can reduce fuel consumption and air pollution from the transit system. A complete transition from the current diesel fleet to BEBs is costly and time-consuming. Thus, the intermediate solution is a combination of diesel, hybrid, and BEBs. Therefore, a planning framework is required that simultaneously tackles three contiguous aspects of transit electrification and their interconnections, namely charging infrastructure, fleet configuration, and scheduling. Accordingly, this study considers a mixed fleet of diesel and BEBs. It aims to concurrently find (i) the optimal location and capacity of charging infrastructure, considering micro-grid specifications, the impact of distributed energy resources, and time-of-use electricity rates and (ii) optimum operation and refueling strategies. Another objective of this study is to capture the impacts of adverse weather conditions on transit electrification. A mixed-integer problem is proposed and solved using a metaheuristic algorithm based on simulated annealing to minimize system costs, including infrastructure, fleet, and operation costs. A subnetwork of transit in Worcester, Massachusetts, is selected as a case study, including three routes, five candidate charging locations, and three bus types. Findings suggest that BEBs can operate and serve the passenger demand with sufficient charging infrastructure. Sensitivity analyses show that even though high-power chargers are more expensive per piece, they reduce the overall cost as fewer chargers are required. The cost rises for chargers with power of 350 kW or more. It is worth noting that the benefits of BEBs are more significant in smaller buses and are heavily affected by adverse weather conditions.
Writing Interventions for Students With Intellectual and Developmental Disabilities: A Meta-Analysis
Authors: Rodgers Derek B. , Loveall Susan J.
Published: August 2022

Students with intellectual and developmental disabilities (IDD) are likely to experience writing challenges that can negatively impact their overall academic, vocational, and social success. The goals of this study were to determine what writing interventions have been used with students with IDD, how their writing skills have been measured, the effects of those interventions, and study-level moderators via meta-analytic procedures. We identified 96 writing-related outcomes reported in 52 studies that included 424 students with IDD. A majority of studies used strategy instruction/self-regulated strategy development (SRSD), direct instruction, or response prompting to instruct writing skills, and the most common outcome measures were related to writing output, conventions, quality rubrics, elements, and spelling. Results indicated that writing interventions led to significant improvements in students’ writing skills. These effects were moderated by intervention type and study quality.
It is time for a national strategy on equitable access to assistive technology in Canada
Authors: Wang Rosalie H. , Wilson Michael G.
Published: August 2022

The time has come to develop and implement a Canadian strategy on equitable access to Assistive Technology (AT). AT use has significant health, social, and economic benefits for people with disabilities and older people, and benefits society by assisting to mitigate the most prominent health and social challenges of our time. Our research with citizens (with/without experiences of disabilities or AT use) and system leaders across Canada determined that access is variable and inequitable, with unmet needs, restricted funding, and inefficiencies. Collaboratively, we devised a blueprint, comprising a policy vision, three priority issues to address, principles to underpin policy actions, and short- and long-term priorities, from which to build a strategy. We hope the blueprint sparks action among citizens and health leaders, especially those working across governments, sectors, and communities to promote leadership and create a cross-jurisdictional coalition to elaborate on a national strategy and action plans for moving forward.
