Mechanical strength and millimeter-wave transmittance spectrum of stacked sapphire plates bonded by sodium silicate solution

Abstract. The polarization modulator unit for the low-frequency telescope in LiteBIRD employs an achromatic half-wave plate (AHWP). It consists of five layers of a-cut sapphire plate, which are stacked based on a Pancharatnam recipe. In this way, the retardance of the AHWP is a half-wave over a bandwidth of 34 to 161 GHz. The diameter of a single sapphire plate is about 500 mm and the thickness is 5 mm. When a large-diameter AHWP is used for a space mission, it is important for the AHWP to survive launch vibration. A preliminary study indicates that the five-layer stacked HWP has a risk of breakage at the launch unless the five layers are glued together and mechanically treated as one disk. We report our investigation using a sodium silicate solution that can bond the sapphire plates. This technique has been previously investigated as a candidate of cryogenic bonding for a mirror material, including sapphire, of the gravitational wave experiments: LIGO, VIRGO, and KAGRA. We experimentally studied the mechanical strength of the bonded interface for two different surface conditions: polished and unpolished. We demonstrated that the tensile and shear strength >20 MPa for samples with a polished surface. This satisfied the requirement of 5.5 MPa derived from the mechanical simulation assuming a launch load of 30 G. We identified that samples glued on a polished surface exhibit higher strength than unpolished ones by a factor of 2 for tensile and 18 for shear strength. We measured the millimeter-wave transmittance between 90 and 140 GHz using sapphire plates with a diameter of 50 mm before and after bonding. We did not find any optical effects caused by the bonded interface within 2% error in transmittance, which originates from the measurement system.

An Observational Study to Assess the Effectiveness of 4CMenB against Meningococcal Disease and Carriage and Gonorrhea in Adolescents in the Northern Territory, Australia—Study Protocol

Invasive meningococcal disease (IMD) causes significant morbidity and mortality worldwide with serogroup B being the predominant serogroup in Australia and other countries for the past few decades. The licensed 4CMenB vaccine is effective in preventing meningococcal B disease. Emerging evidence suggests that although 4CMenB impact on carriage is limited, it may be effective against gonorrhoea due to genetic similarities between Neisseria meningitidis and Neisseria gonorrhoeae. This study protocol describes an observational study that will assess the effect of the 4CMenB vaccine against meningococcal carriage, IMD and gonorrhoea among adolescents in the Northern Territory (NT). All 14–19-year-olds residing in the NT with no contraindication for 4CMenB vaccine will be eligible to participate in this cohort study. Following consent, two doses of 4CMenB vaccine will be administered two months apart. An oropharyngeal swab will be collected at baseline and 12 months to detect pharyngeal carriage of Neisseria meningitidis by PCR. The main methodological approaches to assess the effect of 4CMenB involve a nested case control analysis and screening method to assess vaccine effectiveness and an Interrupted Time Series regression analysis to assess vaccine impact. Research ethics approvals have been obtained from Menzies and Central Australian Human Research Ethics Committees and the Western Australian Aboriginal Health Ethics Committee. Results will be provided in culturally appropriate formats for NT remote and regional communities and published in international peer reviewed journals. ClinicalTrials.gov Identifier: NCT04398849.

Length of Stay Analysis of COVID-19 Hospitalizations Using a Count Regression Model and Quantile Regression: A Study in Bologna, Italy

This study aimed to identify and explore the hospital admission risk factors associated with the length of stay (LoS) by applying a relatively novel statistical method for count data using predictors among COVID-19 patients in Bologna, Italy. The second goal of this study was to model the LoS of COVID patients to understand which covariates significantly influenced it and identify the potential risk factors associated with LoS in Bolognese hospitals from 1 February 2020 to 10 May 2021. The clinical settings we focused on were the Intensive Care Unit (ICU) and ordinary hospitalization, including low-intensity stays. We used Poisson, negative binomial (NB), Hurdle–Poisson, and Hurdle–NB regression models to model the LoS. The fitted models were compared using the Akaike information criterion (AIC), Vuong’s test criteria, and Rootograms. We also used quantile regression to model the effects of covariates on the quantile values of the response variable (LoS) using a Poisson distribution, and to explore a range of conditional quantile functions, thereby exposing various forms of conditional heterogeneity and controlling for unobserved individual characteristics. Based on the chosen performance criteria, Hurdle–NB provided the best fit. As an output from the model, we found significant changes in average LoS for each predictor. Compared with ordinary hospitalization and low-intensity stays, the ICU setting increased the average LoS by 1.84-fold. Being hospitalized in long-term hospitals was another contributing factor for LoS, increasing the average LoS by 1.58 compared with regular hospitals. When compared with the age group [50, 60) chosen as the reference, the average LoS decreased in the age groups [0, 10), [30, 40), and [40, 50), and increased in the oldest age group [80, 102). Compared with the second wave, which was chosen as the reference, the third wave did not significantly affect the average LoS, whereas it increased by 1.11-fold during the first wave and decreased by 0.77-fold during out-wave periods. The results of the quantile regression showed that covariates related to the ICU setting, hospitals with longer hospitalization, the first wave, and the out-waves were statistically significant for all the modeled quantiles. The results obtained from our study can help us to focus on the risk factors that lead to an increased LoS among COVID-19 patients and benchmark different models that can be adopted for these analyses.
A Novel Vision Based Protocol for Controlling Flapping Wing Vehicles in Indoor Surveillance Mission

This paper presents a novel protocol for vision based flight control of flapping wing micro aerial vehicles (FWMAV). The crux of the work intends to use real time video signals from an on-board camera to control the FWMAVs without using any electronic sensor modules and manual remote control system. A unique control interface is framed for indoor surveillance tasks wherein the user will command the vehicle by providing set of vision information to activate certain flight movements. The control interface is programmed through MATLAB which offers user friendly graphical options to perform vision controlled tasks. Initial simulation is carried out to control the FWMAVs through interfacing MATLAB and Proteus software. The simulation test includes controlling the flapping frequency, directivity of the FWMAV and also validating the vision based systems. In addition, the real time experimentation is performed to control the FWMAV through color based signalling. The obtained results accentuate the usefulness of the developed protocol in controlling of FWMAVs with reprogrammable control interface and light-weight camera that with consequential positive impact on vehicle performance.
Application of Maqasid Al-Shariah into Supply Chain Management Practices for Sustainable Development

The study aimed to provide additional insights on how supply chain management practices are used to promote sustainable development in line with Maqasid Al-Shariah principles of Islam. A multiple case study approach involving two major automotive firms in Malaysia was used to address key research issues. The results show that these SCM practices, viz. resources, information, integration, and relationship practices support the promotion of Maslahah for all human beings which is consistent with the aims of Maqasid Al-Shariah principles for sustainable development. The findings provide some guidance to facilitate the achievement of SDGs especially among Muslim countries through their SCM practices. Studies which examined SCM practices for sustainable development from an Islamic perspective are limited. Therefore, the present study aims to provide additional insights on how SCM practices are used to promote sustainable development in line with Maqasid Al-Shariah principles. Some SCM practices are congruent with Maqasid al-Shariah particularly when the practices are examined through the Islamic lens that focuses on the goal of creating value to mankind.
Selection of Hyperspectral Vegetation Indices for Monitoring Yield and Physiological Response in Sweet Maize under Different Water and Nitrogen Availability

This study used hyperspectral reflectance data to evaluate the crop physiological parameters of sweet maize. Principal component analysis (PCA) was applied to identify the wavelengths that primarily contributed to each selected PC. Correlation analysis and multiple linear regression, with a stepwise algorithm, were used to select the best-performing vegetation indices (VIs) for monitoring the yield and physiological response of sweet maize grown under different water and nitrogen availability. The spectral reflectance measurements of crops were taken during the mid-season stage, for two consecutive growing seasons. The multivariate regression results showed that red-edge group indices, such as CARI (Chlorophyll Absorption Reflectance Index), DD (Double Difference Index), REIP (Red-Edge Inflection Point), and Clred-edge (Chlorophyll Red-Edge) indices were good predictors of yield and physiological parameters, confirming the crucial role of the red-edge spectral region that also emerged through PCA. Moreover, DD, REIP, and Clred-edge VIs were able to discriminate transient temporary stress at the mid-season stage, as well as to separate water and N stress levels. Therefore, hyperspectral reflectance VIs can provide valid information to growers, helping them identify and discriminate between different stress conditions.
Telerehabilitation for Managing Daily Participation among Breast Cancer Survivors during COVID-19: A Feasibility Study

We aimed to examine the feasibility and impact of a short-term occupation-based telerehabilitation intervention (Managing Participation with Breast Cancer (MaP-BC)) on daily participation, health-related quality-of-life, and breast-cancer-related symptoms and understand women’s perspectives regarding strategies to manage daily participation and symptoms during COVID-19 pandemic. A mixed-methods study (single-arm pre–post with a qualitative component) included 14 women after their primary medical treatment for breast cancer. Women received six weeks of occupation-based intervention using a video-communication. Sessions focused on identifying functional goals and training strategies to manage daily participation. The primary outcome was perceived performance and satisfaction with meaningful activities by the Canadian Occupational Performance Measure (COPM). Secondary outcomes were participation in the Activity Card Sort (ACS), upper-extremity functioning of Disability Arm Shoulder Hand, self-reported symptom severity, executive-functioning, health-related quality of life, and a question regarding strategies used to manage daily participation. Women significantly improved their daily participation in meaningful activities in the COPM, most ACS activity domains, self-reported executive functioning, and health-related-quality-of-life. Qualitative findings revealed three main themes: (1) daily life under the threats of breast cancer and COVID-19, (2) women’s own strategies to overcome challenges, and (3) contribution of the MaP-BC. Providing telerehabilitation during the COVID-19 pandemic is feasible and successful in improving women’s daily participation after breast cancer.
Interplay between Ca2+/Calmodulin-Mediated Signaling and AtSR1/CAMTA3 during Increased Temperature Resulting in Compromised Immune Response in Plants

Changing temperatures are known to affect plant–microbe interactions; however, the molecular mechanism involved in plant disease resistance is not well understood. Here, we report the effects of a moderate change in temperature on plant immune response through Ca2+/calmodulin-mediated signaling. At 30 °C, Pst DC3000 triggered significantly weak and relatively slow Ca2+ influx in plant cells, as compared to that at 18 °C. Increased temperature contributed to an enhanced disease susceptibility in plants; the enhanced disease susceptibility is the result of the compromised stomatal closure induced by pathogens at high temperature. A Ca2+ receptor, AtSR1, contributes to the decreased plant immunity at high temperatures and the calmodulin-binding domain (CaMBD) is required for its function. Furthermore, both salicylic acid biosynthesis (ICS) and salicylic acid receptor (NPR1) are involved in this process. In addition to stomatal control, AtSR1 is involved in high temperature-compromised apoplastic immune response through the salicylic acid signaling pathway. The qRT-PCR data revealed that AtSR1 contributed to increased temperatures-mediated susceptible immune response by regulating SA-related genes in atsr1, such as PR1, ICS1, NPR1, as well as EDS1. Our results indicate that Ca2+ signaling has broad effects on the molecular interplay between changing temperatures as well as plant defense during plant–pathogen interactions.
Generation of Intense and Temporally Clean Pulses—Contrast Issues of High-Brightness Excimer Systems

In high-brightness excimer systems, the direct amplification of short pulses allows temporal filters to be integral parts of the ultraviolet (UV) amplifier chain, where the only origin of the noise is the amplified spontaneous emission (ASE), generated by the amplifier(s) following the filter. The ASE, however, develops faster than the short main pulse; in this paper, the dynamic short- and long-pulse amplification properties of KrF, XeCl and XeF excimers are studied, with special emphasis on the temporal contrast. It was found that, beyond the saturation of amplification, the relaxation of the B state in KrF, together with the contribution of the absorption of the transiently populated X state in XeCl and XeF, are the main limitations for both the extraction efficiency and the contrast. For all excimers, the stimulated transition rates and the dependence of the achievable contrast on the level of saturation were derived. Local quantities were introduced to characterize the deterioration of the contrast for a unit gain length of KrF amplifiers. A KrF power amplifier of limited gain (G ≈ 3), following the newly introduced nonlinear Fourier filter, is capable of reaching contrast levels beyond the previously reported 1011–1012.
The Energetics and Topology of Grain Boundaries in Magnesium: An Ab Initio Study

First principles calculations were carried out on six different grain boundaries with complex, non-symmetrical, crystallography’s. Solute species (Gd and Zn) were placed in multiple locations to investigate their effect on the boundary energetics. The grain boundaries were found to have an intrinsic grain boundary energy, and this energy was not markedly affected by the solute concentration at the boundary. However, the work of separation (WSEP) was very sensitive to grain boundary chemistry. Boundaries of higher disorder were found to be more sensitive to boundary chemistry and showed higher values of WSEP and in the case of Gd, were more sensitive to solute concentration at the boundary. No correlation between the boundary behaviour and crystallography could be found, apart from the over-riding conclusion that all six boundaries showed markedly different behaviours, and the effect of solute on each were unique.
Resident-Owned Resilience: Can Cooperative Land Ownership Enable Transformative Climate Adaptation for Manufactured Housing Communities?

Abstract Residents of manufactured housing communities (MHCs) are disproportionately vulnerable to both hazards and displacement. The cooperative ownership model of resident-owned communities (ROCs) pioneered by ROC USA helps MHC residents resist displacement, but little research assesses how cooperative tenure impacts hazard vulnerability. To fill this gap, we conduct a spatial analysis of 234 ROC USA sites; analyze the co-op conversion process; and interview ROC USA staff, technical assistance providers, and resident co-op leaders. Although ROC USA communities, like other MHCs, face elevated exposure and sensitivity to hazards, we find that ROC USA’s model supports communities’ adaptive capacity by increasing access to financial resources, bridging formal and informal knowledge and skills, and improving social and institutional capacity. This networked cooperative model represents a scalable form of transformative adaptation by enabling low-income communities to address the underlying causes of uneven hazard vulnerabilities that are intensifying under climate change. We close with public policy and programmatic recommendations to enhance and expand this model.
ESG Risk Disclosure and the Risk of Green Washing

There have been growing calls from capital market participants, regulators and other stakeholders around the globe for transparent measurement and disclosure of information about financially material environmental, social and governance (ESG) Risks. Diverse approaches to and objectives of sustainability standards and frameworks pose the threat of increasing greenwashing, a term which encompasses a wide range of actions which exaggerate and misrepresent ‘green’ credentials . Traditional financial reporting is regulated, mandatory, and required to meet the qualitative characteristics; relevance, reliability, comparability, materiality and understand ability. However, ESG reporting is problematic due to reporting quality which does not meet the above criteria. Apart from that ESG reporting is not regulated in most part of the world. A global framework is needed to prevent fragmentation, provide greater comparability, transparency and reduce the complexity of ESG disclosure which could mitigate the risk of greenwashing as the ESG is increasingly considered to be a fundamental part of effective and sustainable business performance.
Numerical investigation of the flow-field characteristics around the suspended pipeline under oblique flows

The flow field distribution around the suspended pipeline is closely related to the mechanical characteristics and local scour characteristics of the underwater crossing pipelines. To fully investigate the velocity distribution and wake structure characteristics around the suspended pipeline under oblique flows, a flume model test and a numerical simulation based on the LES (Large Eddy Simulation) method were performed. The results showed that the velocity distribution near the suspended pipeline under oblique flows had obvious three-dimensional characteristics. The influence range of pipeline on velocity is 1 d before to 6 d behind the pipeline (d is pipeline diameter). The smaller the flow angle, the more disordered the velocity distribution is. The larger the flow angle, the greater the variation degree of the velocity at each section at the same section is, as well as the higher the velocity deficit value is. In addition, the larger the angle of pipe flow, the more violent the wake structure changes with the flow velocity, and the stronger the regularity of vortex street shedding. This research provides a theoretical reference for the scour prevention design and safe operation of crossing pipelines.

Museum lighting environment: Designing a perception zone map and emotional response models

This paper describes two experiments that were designed to investigate the museum lighting environment in terms of correlated colour temperature and illuminance. The results are reported as visual perceptions and perception zone maps. Experiment 1 was conducted to investigate the impact of the illumination conditions on visual perceptions in a light cabinet. Experiment 2 was the same as Experiment 1, except that it was performed in a museum. The rating scores were combined to establish the perception zone maps on a correlated colour temperature–illuminance plane. Furthermore, two emotional response models, named the visibility model and the warmth model, suitable for museum indoor lighting in small- and large-scale spaces were established. The analytical results indicated that the pleasant zone found in this study partially agrees with Kruithof's rule.
