Optimal trajectory tracking control for a class of nonlinear nonaffine systems via generalized N‐step value gradient learning
Authors: Zhao Mingming , Wang Ding , Qiao Junfei , Hu Lingzhi 
Published: December 2022

SummaryIn this paper, the tracking control problem of unknown nonlinear systems is solved by using the generalized N‐step value gradient learning algorithm with parameter [GNSVGL()]. The GNSVGL() algorithm can provide optimal tracking decisions faster than traditional ones. Initialized by different positive semi‐definite functions, the monotonicity and convergence properties of the proposed algorithm are proven. Under some conditions, the stability analysis of the value‐iteration‐based algorithm is provided. The one‐return and ‐return critic neural networks are constructed to approximate the gradient of the one‐return and ‐return cost functions. The action neural network is employed to approximate the control law of the error system. It is emphasized that one‐return and ‐return critic networks are combined to train the action neural network. Finally, via conducting simulation studies and comparisons, the excellent tracking performance of the proposed algorithm is confirmed.

Published: December 2022

AbstractClassification of natural flow regimes of non‐perennial rivers and streams (NPRS) is an incipient field of research. NPRS represent approximately 70% of the total Mediterranean rivers and are expected to increase in the next decades as a result of climate change. Due to the ecological importance of NPRS and the need to improve national ecological assessment methods within the scope of the Water Framework Directive (WFD), this paper aims to classify the hydrological regime of 69 non‐regulated streams, testing several hydrological indices related to the magnitude, frequency, duration, timing, and rate of change in periods of flow cessation. Using daily flow records, a total of 315 indices were calculated and their relationships were examined with Principal Component Analysis (PCA) for different thresholds used to define zero‐flow condition (0, 1, 2, and 5 L/s). Redundancy analysis identified five indices that better describe the patterns of hydrological variability in Mediterranean NPRS: number of days per year without flow, annual percentage of months without flow, mean daily annual flow, coefficient of variation of Julian date of the annual start of zero‐flow and annual rise rate. Using these indices, a self‐organizing map (SOM) was trained in order to categorize the NPRS into three groups with similar hydrological features. The results of this study provide a statistically‐based hydrological classification of NPRS in Mediterranean environments. We expect that this classification will provide useful insights to water authorities to improve the assessments of the ecological status in this type of water bodies.

Authors: Oke Ayodeji Emmanuel , Kineber Ahmed Farouk , Elseknidy Mohamed , Kayode Fakunle Samuel 
Published: December 2022

AbstractSustainability concepts are adopted via new technologies to achieve the highest gains without compromising the projects' objectives. One of these technologies is radio frequency identification (RFID). This research investigated the influence of various drivers and benefits of RFID implementation on the achievement of sustainable construction projects. A close‐ended questionnaire detailing the necessary variables were administered to relevant construction professionals in the study area. Results of exploratory factor analysis of the data revealed that the drivers of RFID could be grouped into three primary constructs: technology, industry, and culture. However, the benefits of implementing RFID have two primary constructs: resources and environment. This study employed a partial least square structural equation modeling to further evaluate the connections among drivers and the application of RFID in the building industry. Results indicated that implementing RFID in the building industry will aid the sustainability of construction projects. The findings of this study will assist policy makers concerned with the performance and sustainability of construction projects through the adoption of available technologies including RFID.
Salary transparency and gender pay inequality: Evidence from Canadian universities
Authors: Lyons Elizabeth , Zhang Laurina 
Published: December 2022

AbstractResearch AbstractWe examine whether salary transparency influences gender pays inequality in the context of Canadian universities by exploiting a policy change enacted in one Canadian province that required salary disclosure through a publicly searchable database, thus lowering the cost of monitoring the gender pay gap. We find that, on average, salary disclosure improves gender pay equality but institutions respond in different ways. Despite little media attention around gender equality at the time of the policy, institutions most likely to anticipate higher scrutiny, such as top ranked institutions, respond more aggressively to improve gender pay equality—both in terms of the magnitude and type of response. Combined, our findings suggest that the extent of change from salary transparency depends on the reduction in monitoring costs and organizational characteristics.Managerial AbstractSalary transparency has been implemented in various ways around the world as a strategy by firms and policy makers to reduce the gender pay gap. However, whether and how it can achieve this in practice is unclear. We examine a salary transparency policy that mandated disclosure to the public through an online database in one Canadian province by comparing the change in gender pay inequality in that province relative to the change in the gender pay gap in provinces without disclosure. We find that salary transparency improves average gender pay equality primarily within the most visible organizations that likely anticipate high levels of public scrutiny. Our findings imply that facilitating low‐cost public monitoring of gender inequalities can motivate organizations to enact change.
Freezing biological organisms for biomedical applications

Published: December 2022

AbstractBiological organisms play important roles in human health, either in a commensal or pathogenic manner. Harnessing inactivated organisms or living organisms is a promising way to treat diseases. As two types of freezing, cryoablation makes it simple to inactivate organisms that must be in a non‐pathogenic state when needed, while cryopreservation is a facile way to address the problem of long‐term storage challenged by living organism‐based therapy. In this review, we present the latest studies of freezing biological organisms for biomedical applications. To begin with, the freezing strategies of cryoablation and cryopreservation, as well as their corresponding technical essentials, are illustrated. Besides, biomedical applications of freezing biological organisms are presented, including transplantation, tissue regeneration, anti‐infection therapy, and anti‐tumor therapy. The challenges and prospects of freezing living organisms for biomedical applications are well discussed. We believe that the freezing method will provide a potential direction for the standardization and commercialization of inactivated or living organism‐based therapeutic systems, and promote the clinical application of organism‐based therapy.

Authors: Anbazhaghan N , Lakshmanan T , Jayaprabakar J , Prabhu A 
Published: December 2022

AbstractThe present study aims on onsite production of hydrogen using electrolysis process in series and using temporary storage to store the gas and induce it at the required flow rate through the inlet manifold in a dual‐fueled engine along with injecting sapodilla oil through the fuel injector. Sapodilla oil biodiesel is prepared via conventional transesterification with standard operating conditions (65°C) reaction temperature, 3 h reaction time, 1.5% by wt. catalyst and 6:1 molar ratio). Diesel, B100 (100% biodiesel), B100 with two sets of hydrogen induction have been tested for its performance and emissions. Through this analysis it was found that the gas emission such as CO, HC, CO2 was greatly reduced compared to the diesel and sapodilla oil when hydrogen was induced but resulted in increase in NOx emission. There was improvement in parameters with increase in hydrogen induction.
Bulk locality and gauge invariance for boundary-bilocal cubic correlators in higher-spin gravity
Authors: Lysov Vyacheslav , Neiman Yasha 
Published: December 2022

Abstract
We consider type-A higher-spin gravity in 4 dimensions, holographically dual to a free O(N) vector model. In this theory, the cubic correlators of higher-spin boundary currents are reproduced in the bulk by the Sleight-Taronna cubic vertex. We extend these cubic correlators from local boundary currents to bilocal boundary operators, which contain the tower of local currents in their Taylor expansion. In the bulk, these boundary bilocals are represented by linearized Didenko-Vasiliev (DV) “black holes”. We argue that the cubic correlators are still described by local bulk structures, which include a new vertex coupling two higher-spin fields to the “worldline” of a DV solution. As an illustration of the general argument, we analyze numerically the correlator of two local scalars and one bilocal. We also prove a gauge-invariance property of the Sleight-Taronna vertex outside its original range of applicability: in the absence of sources, it is invariant not just within transverse-traceless gauge, but rather in general traceless gauge, which in particular includes the DV solution away from its “worldline”.

is known to describe gravity in terms of both the graviton and the dual graviton. We extend this analysis at the linearised level to find the equations of motion for the first higher dual description of gravity that it contains. We also give a systematic method for finding the additional fields beyond those in the non-linear realisation that are required to construct actions for all of the possible dual descriptions of gravity in the non-linear realisation. We show that these additional fields are closely correlated with the second fundamental representation of $$ {A}_1^{+++} $$

Black hole chemistry, the cosmological constant and the embedding tensor
Authors: Meessen Patrick , Mitsios Dimitrios , Ortín Tomás 
Published: December 2022

Abstract
We study black-hole thermodynamics in theories that contain dimensionful constants such as the cosmological constant or coupling constants in Wald’s formalism. The most natural way to deal with these constants is to promote them to scalar fields introducing a (d − 1)-form Lagrange multiplier that forces them to be constant on-shell. These (d − 1)-form potentials provide a dual description of them and, in the context of superstring/supergravity theories, a higher-dimensional origin/explanation. In the context of gauged supergravity theories, all these constants can be collected in the embedding tensor. We show in an explicit 4-dimensional example that the embedding tensor can also be understood as a thermodynamical variable that occurs in the Smarr formula in a duality-invariant fashion. This establishes an interesting link between black-hole thermodynamics, gaugings and compactifications in the context of superstring/supergravity theories.
Boolean Complexes of Involutions

Published: December 2022

AbstractLet (W, S) be a Coxeter system. We introduce the boolean complex of involutions of W which is an analogue of the boolean complex of W studied by Ragnarsson and Tenner. By applying discrete Morse theory, we determine the homotopy type of the boolean complex of involutions for a large class of (W, S), including all finite Coxeter groups, finding that the homotopy type is that of a wedge of spheres of dimension $$\vert S\vert -1$$

‘C’mon, let’s talk: a pilot study of mental health literacy program for Filipino migrant domestic workers in the United Kingdom
Authors: Martinez Andrea B. , Lau Jennifer Y. F. , Morillo Hannah Misha , Brown June S. L. 
Published: December 2022

Abstract
Purpose
This pilot study of a culturally adapted online mental health literacy (MHL) program called ‘Tara, Usap Tayo!’ (C’mon, Let’s Talk) aims to assess the acceptability, appropriateness, feasibility, and potential effectiveness in improving the help-seeking behavior of Filipino migrant domestic workers in the United Kingdom (UK).

Methods
Using mixed methods, we conducted a non-randomized single-group study of the online MHL program with 21 participants. The development of this intervention was guided by the Medical Research Council Framework for developing complex interventions and utilized Heim & Kohrt’s (2019) framework for cultural adaptation. Content materials from the WHO Mental Health Gap Action Program (mhGAP), WHO Problem Management Plus (PM +) and Adult Improving Access to Psychological Therapies (IAPT) were modified and translated into the Filipino language. The MHL program was delivered online in three sessions for two hours each session. Data were collected at three time points: (T1) pretest; (T2) posttest; and (3) follow-up test. Quantitative data on participants’ attitudes towards help-seeking and level of mental health literacy as outcome measures of potential intervention effectiveness were collected at T1, T2 and T3, while focus group discussions (FGDs) to assess participants’ feedback on the acceptability, feasibility, and appropriateness of the online MHL program were conducted immediately at T2. Data analysis was done using a thematic approach for qualitative data from the FGDs and descriptive statistics and repeated-measures ANOVA were used to assess the difference in the T1, T2, and T3 tests. Both quantitative and qualitative results were then integrated and triangulated to answer the research questions.

Results
The online MHL program is generally acceptable, appropriate, and feasible for use among Filipino migrant domestic workers. Preliminary findings lend support for its possible effectiveness in improving mental health literacy and help-seeking propensity. The cultural adaptation made in the content, form, and delivery methods of the intervention was acceptable and feasible for this target subcultural group.

Conclusion
By improving their mental health literacy and help-seeking propensity, this online MHL program has the potential to provide support to the mental health and well-being of Filipino migrant domestic workers in the UK. Further feasibility study or large-scale randomized controlled trial is needed to confirm the preliminary findings of this study.
Secondary immune-mediated thrombotic thrombocytopenic purpura in idiopathic inflammatory myopathy: a case-based review
Authors: Ruffer Nikolas , Holzer Marie-Therese , Bal Lukas Can , Melderis Simon , Krusche Martin , Huber Tobias B. , Kötter Ina 
Published: December 2022

AbstractImmune-mediated thrombotic thrombocytopenic purpura (iTTP) is a potentially fatal acquired thrombotic microangiopathy syndrome that frequently develops in the context of infectious diseases or systemic autoimmune conditions including connective tissue diseases. We report the case of a 42-year-old female suffering from severe iTTP associated with anti-Jo-1 positive antisynthetase syndrome, which was successfully treated with combination therapy of intravenous immune globulin, rituximab and plasma exchange. Based on a systematic review of the literature, two additional cases of idiopathic inflammatory myopathy-associated iTTP (secondary iTTP) were identified. In conclusion, iTTP may be a rare complication of IIM that clinicians should consider in cases of marked thrombocytopenia. Further work-up of this finding should include a peripheral blood smear (schistocyte count) and ADAMTS13 activity. The concomitant manifestation of these autoimmune conditions may require intensive immunosuppressive therapy.

Published: December 2022

Abstract
Objectives
Upright computed tomography (CT) can detect slight changes particularly in the superior vena cava (SVC) volume in healthy volunteers under the influence of gravity. This study aimed to evaluate whether upright CT-based measurements of the SVC area are useful for assessing mean right atrial pressure (mRAP) in patients with heart failure.

Methods
We performed CT in both standing and supine positions to evaluate the SVC (directly below the junction of the bilateral brachiocephalic veins) and inferior vena cava (IVC; at the height of the diaphragm) areas and analyzed their relationship with mRAP, measured by right heart catheterization in 23 patients with heart failure.

Results
The median age of enrolled patients was 60 (51−72) years, and 69.6% were male. The median mRAP was 3 (1−7) mmHg. The correlations between the standing position SVC and IVC areas and mRAP were stronger than those in the supine position (SVC, ρ = 0.68, p < 0.001 and ρ = 0.43, p = 0.040; IVC, ρ = 0.57, p = 0.005 and ρ = 0.46, p = 0.026; respectively). Furthermore, the SVC area in the standing position was most accurate in identifying patients with higher mRAP (> 5 mmHg) (SVC standing, area under the receiver operating characteristic curve [AUC] = 0.91, 95% confidence interval [CI], 0.77–1.00; SVC supine, AUC = 0.78, 95% CI, 0.59–0.98; IVC standing, AUC = 0.77, 95% CI, 0.55–0.98; IVC supine, AUC = 0.72, 95% CI, 0.49–0.94). The inter- and intraobserver agreements (evaluated by intraclass correlation coefficients) for all CT measurements were 0.962–0.991.

Conclusions
Upright CT-based measurement of the SVC area can be useful for non-invasive estimation of mRAP under the influence of gravity in patients with heart failure.

Key Points
• This study showed that the superior vena cava (SVC) area in the standing position was most accurate in identifying patients with heart failure with higher mean right atrial pressure.
• Upright computed tomography-based measurements of the SVC area can be a promising non-invasive method for estimating mean right atrial pressure under the influence of gravity in patients with heart failure.
• Clinical management of patients with heart failure based on this non-invasive modality may lead to early assessment of conditional changes and reduced hospitalization for exacerbation of heart failure.

Published: December 2022

Abstract
Purpose
The primary aim of this study was to assess patient-centeredness of endometriosis care in a national sample of Swedish women with endometriosis. The secondary aims were to assess the importance of different dimensions of endometriosis care and to analyze demographic and clinical determinants associated with the experience of patient-centeredness.

Methods
This cross-sectional study included 476 women with confirmed endometriosis. An invitation to participate was sent to 1000 randomly selected women aged ≥ 18 years having any endometriosis diagnosis and who had visited a gynecological clinic due to endometriosis problems any time during the past five years. Participants were recruited from ten different-sized gynecology clinics all over Sweden. The invitation letter had a link to the digital survey, which consisted of demographic and clinical questions, and the ENDOCARE questionnaire (ECQ). ECQ measures experiences, importance and patient-centeredness of ten dimensions of endometriosis care. Univariate and multiple regression analyses were used to analyze which patient-specific demographic and clinical determinants were associated with the experience of patient-centeredness.

Results
The response rate was 48%. The results indicate that Swedish women with endometriosis experience low patient-centeredness and rate relational aspects with healthcare professionals as the most important aspects of care. Having a gynecologist with patient responsibility was an independent predictor for high patient-centeredness.

Conclusion
Women with endometriosis in Sweden experience low patient-centeredness, reflecting the urgent need for improvement. More effort should be given to develop the relational aspects of care. Women with endometriosis should have a responsible gynecologist to care for treatment and follow-up.
Dosimetric evaluation study of IMRT and VMAT techniques for prostate cancer based on different multileaf collimator designs

Published: December 2022

AbstractThe hypofractionated radiotherapy modality was established to reduce treatment durations and enhance therapeutic efficiency, as compared to conventional fractionation treatment. However, this modality is challenging because of rigid dosimetric constraints. This study aimed to assess the impact of multi-leaf collimator (MLC) widths (10 mm and 5 mm) on plan quality during the treatment of prostate cancer. Additionally, this study aimed to investigate the impact of the MLC mode of energy on the Agility flattening filter (FF), MLC Agility-free flattening filter (FFF), and MLCi2 for patients receiving hypofractionated radiotherapy. Two radiotherapy techniques; Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Radiotherapy (VMAT), were used in this research. In the present study, computed tomography simulations of ten patients (six plans per patient) with localized prostate adenocarcinoma were analyzed. Various dosimetric parameters were assessed, including monitor units, treatment delivery times, conformity, and homogeneity indices. To evaluate the plan quality, dose-volume histograms (DVHs) were estimated for each technique. The results demonstrated that the determined dosimetric parameters of planning target volume (PTV)p (such as D mean, conformity, and homogeneity index) showed greater improvement with MLC Agility FF and MLC Agility FFF than with MLCi2. Additionally, the treatment delivery time was reduced in the MLC Agility FF (by 31%) and MLC Agility FFF (by 10.8%) groups compared to the MLCi2 group. It is concluded that for both the VMAT and IMRT techniques, the smaller width (5 mm) MLCs revealed better planning target volume coverage, improved the dosimetric parameters for PTV, reduced the treatment time, and met the constraints for OARs. It is therefore recommended to use 5 mm MLCs for hypofractionated prostate cancer treatment due to better target coverage and better protection of OARs.
