Published: June 2023

Abstract

Background: Wilson Disease (WD) is a rare metabolic disorder of impaired copper transport manifesting in hepatic, neurological, and psychiatric symptoms. To evaluate the clinical symptoms of WD in clinical trials, a group of clinicians created the Unified Wilson Disease Rating Scale (UWDRS). Content validity of this scale has not been established. The aim of this study was to evaluate the content validity of the UWDRS Part II from the patient perspective. This study utilized multiple qualitative research methods including concept elicitation interviews, concept/instrument mapping, and cognitive debriefing interviews.
Results: Concept elicitation interviews with a sample of WD patients with one or more neurological signs/symptoms identified several signs, symptoms, and impacts related to neurological dysfunction, strengthening our understanding of the importance of the neurological aspects of the WD patient experience. Mapping neurological concepts to Part II and III items of the UWDRS showed complete coverage of all salient neurological concepts and near complete coverage of all neurological concepts reported by patients in concept elicitation interviews. Item debriefing of Part II of the UWDRS revealed that patients generally found the items clear and personally relevant to their experience with WD.
Conclusions: Overall, the findings from this study provides evidence for the content validity of the UWDRS Part II and supportive evidence for the content validity of Part III. The UWDRS should be used in conjunction with additional clinical outcomes assessments, specifically those evaluating the hepatic and psychiatric signs/symptoms of WD, to provide a comprehensive evaluation of the WD patient experience.

Published: June 2023

Abstract
For an ideal $I$ of a commutative ring $R$, we classify the set of all $3$-zero divisor elements of $R$ with respect to $I$. We prove that if $\bigcap_{i=1}^n P_i$ is a minimal prime decomposition of $\sqrt{I}$, then all elements of \begin{center} $\displaystyle{\bigcup_{i=1}^n P_i-\Big( \bigcup_{j=1}^n \Big\{x\in\bigcap_{i\in \{1,2,\ldots,n\}-\{j\}} P_i\backslash P_j: P_j\subseteq I:_Rx \Big\} \cup \sqrt{I}\Big)}$ \end{center} are $3$-zero divisor elements of $R$ with respect to $I$. Moreover, we determine $3$-zero divisors elements of $R$ with respect to $I$, when either $\sqrt{I}=I$ or $I$ is a primary ideal. Afterwards, we introduce quasi $3$-zero divisor element of $R$ with respect to $I$ and by using the minimal prime ideals of $R$ containing $I$ we characterize these elements. Moreover, we define quasi 3-zero divisor hypergraph of $R$ with respect to $I$ and we determine some properties of this hypergraph with the algebraic properties of $R$.

Published: June 2023

Abstract
In urban water supply systems, pump stations are the hubs for making the complete systems operate regularly as well as the main energy-consuming units. In order to address the current problems of water supply systems, such as high energy consumption and low efficiency of the pump station operation, large fluctuations of liquid levels of the clean water reservoirs, and poor response and adaptability to disturbance events, a digital twin (DT)-based full-process dynamic pump station scheduling method for energy-saving optimization in water purification plants was proposed in this study. To be specific, the DT technology was introduced to monitor production disturbance in real time, trigger the rescheduling process in time, and make a fast response to disturbance events during production, so as to provide technical and methodological support for unattended pump stations. The results of experiments revealed that an average energy-saving rate of 9.78% could be achieved by using the proposed method on the premise of ensuring the full-process dynamic water balance. In addition, the method could maintain high efficiency during the operation of the pumps, and guarantee the safety and stability of the pump stations.
A PSO optimized novel PID Neural Network model for Temperature Control of Jacketed CSTR: Design, Simulation, and a Comparative Study
Authors: Chaturvedi Snigdha , Kumar Narendra , Kumar Rajesh 
Published: June 2023

Abstract
This paper proposes a Particle Swarm Optimization (PSO) tuned novel Proportional Integral Derivative (PID) like neural network (PID-NN). The structure of proposed PID-NN is very simple having only 3 neurons in the hidden layer and a single output neuron. The proportional, integral, and derivative gains of the PID controller are represented by the three weights in the neural network's output layer, respectively. The suggested approach uses the PSO method to optimize the output layer weights, which correspond to PID gains. The non-linear Continuous Stirred Tank Reactor (CSTR) plant, one of the most popular chemical industry processes, is utilized to test the suggested approach. A jacketed CSTR's temperature is controlled via a Particle Swarm Optimization tuned PID like neural network (PSO-NN-PID) controller. In terms of time domain specifications, the performance of the PSO-based NN-PID controller, the back propagation-based NN-PID controller (BP-NN-PID), and the conventionally tuned PID controller are compared. Mean square error is the objective function used in PSO-NN-PID and BP-NN-PID to optimize PID settings. The results show that the overshoot decreases from 44.13% in case of Zeigler- Nichols tuned PID controller to 26.33% in case of BPNN-PID controller, and further reduces to 23.13% in case of proposed PSO-based NN-PID controller. The decrease in rise time is observed from 0.2727 seconds in case of BPNN tuned PID to 0.1283 seconds in case of proposed PSO-NN-PID controller.
Effects of vibrating compaction time on fiber and aggregate distribution and strength of ultra-high performance concrete

Published: June 2023

Abstract
In this study, we investigated the settling velocity and distribution between steel fiber and aggregate during vibrating compaction of ultra-high performance concrete (UHPC) mixtures. In addition, we explored the effect of fiber distribution characteristics on the UHPC strength. Based on Stokes’ theorem and considering the vibration effect, a method for calculating the settling velocity of steel fiber and aggregate in UHPC mixtures during vibrating compaction was proposed. The fiber/aggregate dispersion coefficient based on the proposed method decreased gradually with time. The experimentally obtained fiber dispersion coefficient first increased and then decreased, with the maximum value appearing at 5 s. In contrast, the fiber orientation coefficient gradually increased with time. Moreover, following vibration excitations at different times, the fiber dispersion coefficient increased and the fiber orientation coefficient decreased as the yield stress and plastic viscosity of the UHPC mixtures increased. In the vibration range of 0–15 s, the compressive and flexural strength of UHPC first increased and then decreased, with the maximum values appearing at 5 and 10 s, respectively. The compressive strength was affected by the fiber dispersion coefficient, whereas the flexural strength was affected by the fiber dispersion and orientation coefficients. Furthermore, the relational expression between compressive/flexural strengths of UHPC and fiber dispersion and orientation coefficients were presented.

Published: June 2023

Abstract
In this work, (rGO)/TiO2/NiFe2O4 or GTN nanocomposites were prepared as novel photocatalysts and strong antibacterial agents using a facile, cheap, and scalable hydrothermal method. To prepare the nanocomposites, different mass ratios of rGO:TiO2:NiFe2O4 were chosen as 1:1:1, 2:1:1, 3:1:1, and 4:1:1, and they called as GTN111, GTN211, GTN311, and GTN411, respectively. The photocatalytic results showed that 0.1 mg.mL− 1 of composite degrades 95% and 89% of 20 ppm methylene blue (MB) under UV and visible light irradiation, respectively. Under visible exposure, the first-order rate constant was calculated as 90×10− 3 min− 1 for GTN211 nanocomposite. It was found that the holes and OH radical species play the main role in degradation of MB. The antibacterial activity of the best photocatalyst, i.e., GTN211, against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) was also investigated. The minimum inhibitory concentration of GTN211 was measured as 1 mg.mL− 1 for E. coli and S. aureus. The value of minimum bactericidal concentration of GTN211 was meaured as 0.8 and 1 mg.mL− 1 for E. coli and S. aureus, respectively.

Published: June 2023

Abstract
Seas, marine ecosystems, and coastal regions are crucial components of our environment. To boost fisheries and aquaculture productivity, numerous scientific strategies have been used. A fuzzy-logic-based model is created in the current effort to produce fisheries in India, which ranks fourth in the world for fisheries production. Five input variables, such as fish seed, export, post harvesting, released fund, and temperature, are considered as inputs, and the production of fisheries is taken as the output variable. A Mamdani-type fuzzy inference system with trapezoidal membership functions is prepared with 243 rules in the IF-THEN format. This mathematical model investigates the impacts of input parameters on the production of Indian fisheries. From the system, we observed that fish seed, export, released fund, and post-harvesting facilities positively impact fisheries production. However, a very high temperature is not suitable for high production, even if all other parameters lie at their desired level. Lastly, we have fitted the model with real-world data.

Published: June 2023

Abstract
Background
Previous researches in Sjogren’s syndrome (SS) have showed that acupuncture has effectiveness in alleviating xerostomia and clinical symptoms. While other studies held different viewpoints and results. Therefore, a systematic review and meta-analysis should be conducted to evaluate its efficacy on xerostomia in SS patients.
Methods and analysis:
8 databases will be retrieved from inception to February 20, 2023. They are China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP database, Chinese Biomedical Literature Database (CBM/SinoMed), Embase, PubMed, Cochrane Library and Web of Science. The languages are restricted to Chinese and English. Only randomized controlled trials (RCT) of acupuncture on SS patients will be included. The data screening, extraction and assessment of risk of bias (ROB) will be conducted by 2 researchers individually. The GRADE assessment will be used to evaluate the quality of evidence. The RevMan V.5.3 software will help with pairwise meta-analysis and ADDIS software with network meta-analysis. Moreover, meta-regression and subgroup analysis will be performed to discuss the possible underlying causes of heterogeneity. The primary outcome is the change of xerostomia symptoms. The secondary outcomes include changes in salivary flow, quality of life, oral health, ESSPRI index, ESSDAI index, inflammation severeness and adverse effects.
Results
This systematic review and network meta-analysis will demonstrate how well acupuncture treats xerostomia in SS patients compared with placebo or other interventions.
Ethics and dissemination:
Ethical approval is not applicable and the results will be peer-reviewed and published in a journal.

Periostin facilitates ovarian cancer recurrence by enhancing cancer stemness
Authors: Huang Zhiqing , Byrd Olivia , Tan Sarah , Knight Bailey , Lo Gaomong , Taylor Lila , Berchuck Andrew , Murphy Susan K. 
Published: June 2023

Abstract
The high lethality of Ovarian cancer (OC) is due to high recurrence and development of chemo-resistance, which requires synergy between cancer cells and tumor microenvironment (TME). Analysis of gene microarray from paired primary and recurrent OC tissues revealed significantly elevated expression of the gene encoding periostin (POSTN) in recurrent OC compared to matched primary tumors (p = 0.014). OC cells cultured with conditioned media with high levels of POSTN (CMPOSTNhigh) exhibited faster migration, more invasiveness (p = 0.006), and more chemoresistance (p < 0.05) compared to OC cells cultured with control medium (CMCTL). Furthermore, CMPOSTNhigh-cultured HEYA8 cells demonstrated increased resistance to paxlitaxel-induced apoptosis. OC cell lines cultured with CMPOSTNhigh showed increases in stem cell side population relative to CMCTL-cultured cells. POSTN-transfected 3T3-L1 cells exhibited more intracellular and extracellular lipids and was linked to increased cancer cell expression of the oncogene fatty acid synthetase. Additionally, POSTN functions in the TME were linked to AKT pathway activities. In a xenograft mouse model of OC, the mean tumor volume in mice injected with CMPOSTNhigh-grown OC cells was larger than that in mice injected with CMCTL-grown OC cells (p = 0.0023). Our results bolster the need for further study of POSTN as a potential therapeutic target and potential prevention of recurrent OC.
