Abstract
The radiation damage in optical materials mostly manifests itself as the loss of optical transmittance. The optical materials recover from radiation damage to some extent when the radiation exposure is stopped. The recovery is at a faster rate in the presence of stimulating light. On the other hand, a systematic study of the dynamics of the recovery as a function of the stimulating light parameters such as its wavelength, intensity and exposure duration and method has not been performed in detail yet.

We established an LED recovery station which provides pulsed and continuous light at various wavelengths at custom geometries. We irradiated soda lime glass samples at a rate of 87.5 Gy/min to a total dose of 3.5 kGy and 7.0 kGy. The optical transmittance of the samples were then measured in 200 nm–1500 nm range for an extended period of time. The recovery from radiation damage is improved, both in terms of timing and quantity, as the wavelength of the stimulating light decreases. Around 50% improvement was measured both in recovery rate and the permanent damage when UV LED with a wavelength of 396 nm was used for stimulation. The trend is such that wavelengths deeper in the UV range would result in faster and more effective recovery from radiation damage. The LED stimulated recovery technique from radiation damage is a feasible implementation for the optical active media of radiation and particle detectors which operate in high radiation environments.

Abstract
In this study, an artificial compound eye lens (ACEL) was fabricated using a laser cutting machine and polyvinyl alcohol (PVA) solution. A laser cutter was used to punch micro-sized holes (500 μm diameter—the smallest possible diameter) into an acrylic plate; this punched plate was then placed on the aqueous PVA solution, and the water was evaporated. The plate was used as the mold to obtain a polydimethylsiloxane (PDMS) micro lens array film, which was fixed to a dome-shaped three-dimensional-printed mold for further PDMS curing, and a hemispherical compound eye lens was obtained. Using a gallium nitride (GaN) photodetector, a light detection experiment was performed with the ACEL, bare lens, and no lens by irradiating light at various angles under low temperatures. The photodetector with the ACEL generated a high photocurrent under several conditions. In particular, when the light was irradiated at 0° and below −20 °C, the photocurrent of the GaN sensor with the ACEL increased by 61% and 81% compared with the photocurrent of the GaN sensor with the bare lens and without a lens, respectively. In this study, a sensor for detecting light with ACEL was demonstrated in low-temperature environments, such as indoor refrigerated storages and external conditions in Antarctica and Arctic.

Abstract
Poly-caprolactone is one of the most promising biocompatible polymers on the market, in particular for temporary devices that are not subjected to high physiological loads. Even if completely resorbable in various biological environments, poly-caprolactione does not play any specific biological role in supporting tissue regeneration and for this reason has a limited range of possible applications. In this preliminary work, for the first time l-dopa and fibroin have been combined with electrospun poly-caprolactone fibers in order to induce bioactive effects and, in particular, stimulate the proliferation, adhesion and osteoconduction of the polymeric fibers. Results showed that addition of low-molecular weight fibroin reduces the mechanical strength of the fibers while promoting the formation of mineralized deposits, when tested in vitro with KUSA-A1 mesenchymal cells. l-dopa, on the other hand, improved the mechanical properties and stimulated the formation of agglomerates of mineralized deposits containing calcium and phosphorous with high specific volume. The combination of the two substances resulted in good mechanical properties and higher amounts of mineralized deposits formed in vitro.

Abstract
Hot extremes, ultraviolet (UV) radiation, and surface ozone all have prominent effects on human health and ecosystems. Here we show evidence that both hot extremes and high surface UV radiation at noon time occur concurrently in summer over the Yangtze Plain. Composite analysis suggests that hot extremes in summer are primarily caused by the westward extension of the Western Pacific Subtropical High, which leads to less clouds and consequently more downward solar radiation on the surface over the Yangtze Plain. It is found that surface UV radiation may be dominated by cloud variations, instead of stratospheric ozone during the hot extremes. Further analysis indicates that the hot extremes and high UV radiation, which play important roles in photochemistry in the troposphere, may result in more surface ozone. The concurrent hot extremes, strong UV radiation, and severe ozone pollutions over the Yangtze Plain in summer are likely to have dramatical influences on human health, which should be paid more attention.

Abstract
Nowadays, the consumption of probiotic yogurt has been a significant increase. Mostly people prefer to consume probiotic yoghurt because of its taste and high nutrients. However, in the manufacturing process of probiotic yogurt, a thermal process causes some nutritional losses, e.g., β-carotene. Therefore, to replace the loss of β-carotene during this thermal process, then added an extract of Podang Urang mango (Mangifera indica L.). Podang Urang Mango is one of the famous fruits favored by consumers in Kediri, East Java. This fruit is available in a significant amount in Kediri, so the sustainability of the probiotic yogurt with the addition of Podang mango will be acceptable. This research objective was to determine the quality properties and β-carotene of the probiotic yogurt supplemented with Podang Urang mango extract. The probiotic yogurt was made by adding 3% (v/v) of starter culture (Lactobacillus delbrueckii subsp bulgaricus RRAM-01 and Streptococcus salivarius subsp thermophilus RRAM-01) and Podang Urang Mango extract at 0%, 2%, 4%, 6%, 8%, and 10% (v/v) divided in four replications. pH, titratable acid, viscosity, and β- carotene content included as the observed variables. The results showed that Podang Urang mango extract had a significant effect on the quality properties, which could significantly lower the pH, increase the titratable acid, and increase the viscosity of probiotic yogurt. The thermal process of making probiotic yoghurt at 85-90°C for 35 minutes had lowered the amount of β-carotene. However, the supplementation of Podang Urang mango extract showed significantly increase the yogurt β-carotene. The increase of β-carotene could be influenced by the use of Podang Urang mango extract in yoghurt. The more Podang Urang mango extract added, the greater the β-carotene content found in yoghurt.

AbstractFermentation technology has been used for decades for dairy and meat products. Several studies have shown an increase in the nutritional value of fermented meat and can increase its safety and shelf life. Bekamal is a traditional fermented meat product found in Banyuwangi Regency. Lactic acid bacteria is one of the natural microbiota of meat that is widely used as a fermentation agent to maintain quality and improve the product’s hygiene and sensory properties. This study aimed to indetify lactic acid bacteria (LAB) from traditional fermented meat products, namely bekamal. Bekamal tested is meat that has undergone a fermentation process for 7, 14 and 21 days, and each fermentation time consists of one sample to be isolated and identified the presence of lactic acid bacteria in it. The results showed that in bekamal, some lactic acid bacteria were indicated by Gram staining results, namely gram-positive and catalase-positive, and the results of the CO2 production test were classified as heterofermentative bacteria. This research concluded that in bekamal, lactic acid bacteria were indicated from Lactobacillus, Streptococcus and Leuconostoc genus.

Abstract
Metal sulfides play a major role in determining the friction and wear performance of the brake friction composites. The usage of the combinations of metal sulfides improves tribological performance compared to its individual metal sulfides in the formulation of friction material. In this work, the effect of the Bismuth III sulfide and Iron disulfide combination was evaluated against the tribological performance in the formulation of the friction materials. Six brake friction pads were developed by properly balancing the weight percentage of Bismuth III sulfide and Iron disulfide in the formulation. The tribological performance of the friction liners was studied using a chase tribo-meter following the IS2742 test protocol. The worn surfaces of the brake pad samples were examined for its surface morphology and elemental behaviour using a Scanning electron microscope and an Energy-dispersive x-ray spectroscope. It was observed that the partial replacement of the Bismuth III sulfide with Iron sulfide improves the friction and fade performance. The abrasive nature of the Iron sulfide in the friction pad increases the coefficient of friction and causes the high wear loss beyond the ratio of 4:6 of the mixed sulfides. A statistical approach named preference selection Index was employed to rank the brake friction materials based on the multiple performance criteria.

Abstract
In the wide world of 2D materials, hexagonal boron nitride (hBN) holds a special place due to its excellent characteristics. In addition to its thermal, chemical and mechanical stability, hBN demonstrates high thermal conductivity, low compressibility, and wide band gap around 6 eV, making it a promising candidate for many groundbreaking applications and more specifically in van der Waals heterostructures. Millimeters scale hBN crystals are obtained through a disruptive dual method (polymer derived ceramics (PDC)/pressure-controlled sintering (PCS)) consisting in a complementary coupling of the PDC route and a PCS process. In addition to their excellent chemical and crystalline quality, these crystals exhibit a free exciton lifetime of 0.43 ns, as determined by time-resolved cathodoluminescence measurements, confirming their interesting optical properties. To go further in applicative fields, hBN crystals are then exfoliated, and resulting boron nitride nanosheets (BNNSs) are used to encapsulate transition metal dichalcogenides (TMDs). Such van der Waals heterostructures are tested by optical spectroscopy. BNNSs do not luminesce in the emission spectral range of TMDs and the photoluminescence width of the exciton at 4 K is in the range 2–3 meV. All these results demonstrate that these BNNSs are of high quality and relevant for future opto-electronic applications.

Abstract
The catalyst particles were removed from fluid catalytic cracking (FCC) slurry oil by two-step separation processing. FCC slurry oil was mixed with water and surfactant to make the lower viscosity emulsion. The catalyst particles were removed from the emulsion using the modified hydrophobic ceramic membrane (0.1 μm) and then the water was filtered out from oil/water emulsion using an unmodified hydrophilic ceramic membrane (0.05 μm) at room temperature. The separation efficiency of catalyst particles and emulsion reached 99.9% and the oil/water separation efficiency also reached 99.9%. FCC slurry oil was effectively purified at room temperature by a two-step treatment.
Aesthetic Experience and Intellectual Pursuits
Authors: Schellekens Elisabeth 
Published: May 2022

AbstractThe main aim of this paper is to examine the practice of describing intellectual pursuits in aesthetic terms, and to investigate whether this practice can be accounted for in the framework of a standard conception of aesthetic experience. Following a discussion of some historical approaches, the paper proposes a way of conceiving of aesthetic experience as both epistemically motivating and epistemically inventive. It is argued that the aesthetics of intellectual pursuits should be considered as central rather than marginal to our philosophical accounts of aesthetic experience, and that our views about the relation between the aesthetic and cognitive domains should be reconfigured accordingly.
Linearized maximum rank correlation estimation
Authors: Shen Guohao , Chen Kani , Huang Jian , Lin Yuanyuan 
Published: May 2022

Summary
We propose a linearized maximum rank correlation estimator for the single-index model. Unlike the existing maximum rank correlation and other rank-based methods, the proposed estimator has a closed-form expression, making it appealing in theory and computation. The proposed estimator is robust to outliers in the response and its construction does not need knowledge of the unknown link function or the error distribution. Under mild conditions, it is shown to be consistent and asymptotically normal when the predictors satisfy the linearity of the expectation assumption. A more general class of estimators is also studied. Inference procedures based on the plug-in rule or random weighting resampling are employed for variance estimation. The proposed method can be easily modified to accommodate censored data. It can also be extended to deal with high-dimensional data combined with a penalty function. Extensive simulation studies provide strong evidence that the proposed method works well in various practical situations. Its application is illustrated with the Beijing PM 2.5 dataset.
The Political Economy of Crime: Did Universal Credit Increase Crime Rates?
Authors: Tiratelli Matteo , Bradford Ben , Yesberg Julia 
Published: May 2022

AbstractInterest in the political economy of crime goes back to sociology’s founding fathers, but the nature of the relationship between restrictive social security systems and crime remains contested. This paper exploits exogenous variation in the introduction of Universal Credit (UC) to local areas across England and Wales to address this question. We first use fixed effects models, with a range of controls, to show that as UC enrolments increase in a given area, so does the crime rate. We then use interrupted time series analysis to show that, despite UC being rolled out at different times in different places, its introduction in each local area coincides with a positive shift in the trend in crime. These findings hold for total crime, property crime and violent crime. Borrowing from Strain Theory and Routine Activities Theory, we suggest that changes to the pool of motivated offenders may help to explain these correlations.

Authors: Le Victoria , Pascopella Lisa , Westenhouse Janice , Barry Pennan 
Published: May 2022

Abstract

Background
Recognizing pulmonary involvement in tuberculosis (TB) patients is necessary to prevent TB transmission. We describe frequency and characteristics of patients with extrapulmonary TB (EPTB), normal chest radiographs, and positive sputum culture.

Methods
We analyzed data of patients ≥15 years of age with EPTB reported to the California TB registry during 2011–2017 with cultured sputum and normal chest radiographs using generalized linear modeling to estimate prevalence ratios associated with positive sputum culture. Demographic, behavioral, clinical characteristics, and testing were compared for patients with positive and negative sputum culture.

Results
Of 1635 patients with EPTB and normal chest radiographs, 937 (57%) had sputum culture performed, and 127 (13%) patients had positive results for Mycobacterium tuberculosis complex. Patients with positive results were more likely to: be male, experience homelessness, use substances, have HIV, and have &gt;1 disease site. Among 85 patients with HIV co-infection, 54% had positive culture results compared with 9.5% among 852 patients without HIV co-infection. Patients with EPTB in more than 1 site were also more likely to have a positive sputum culture.

Conclusions
Culturing sputum from patients with EPTB identified pulmonary cases not detected by chest radiograph, particularly among patients with HIV or &gt;1 disease site.
New aspects in cardiorenal syndrome and HFpEF
Authors: Méndez Ana Belén , Azancot Maria Antonieta , Olivella Aleix , Soler María José 
Published: May 2022

ABSTRACT
Cardiorenal syndrome (CRS) is a complex disease in which the heart and kidneys are simultaneously affected, and subsequently, the malfunction of one organ promotes the deterioration of the other. Heart failure (HF) with preserved ejection fraction (HFpEF) is the most common form of HF. The pathophysiology of CRS is not well known and several mechanisms have been proposed. An elevation of central venous pressure seems to be one of the key points to consider, among others such as an increase in intraabdominal pressure. Several diagnostic tools have been identified to establish the diagnosis of CRS in patients with HFpEF. Currently, the availability of biomarkers of renal and cardiac injury, the use of pulmonary ultrasound, the monitoring of the size of the inferior vena cava and the study of the renal venous pattern offer a new dimension in accurately diagnosing and quantifying organ damage in CRS. Beyond the symptomatic treatment of congestion, until recently specific therapeutic tools for patients with CRS and HFpEF were not available. Interestingly, the development of new drugs such as the angiotensin/neprilysin inhibitors and sodium-glucose cotransporter-2 (SGLT-2) inhibitors offer new therapeutic strategies with potential benefits in reduction of cardiorenal adverse outcomes in this population. Randomized clinical trials that focus on patients with HFpEF are currently ongoing to delineate optimal new treatments that may be able to modify their prognosis. In addition, multidisciplinary teamwork (nephrologist, cardiologist and nurse) is expected to decrease the number of visits and the rate of hospitalizations, with a subsequent patient benefit.
School Social Work Practice in Charter Schools: Current Trends and Future Considerations
Authors: Badillo-Diaz Marina Angela 
Published: May 2022

AbstractSince the establishment of the first charter school in 1991, over 7,000 charter schools have opened across the United States. Charter schools are publicly funded schools that are exempt from some of the local or state regulation and serve as alternatives to the more traditional public and private schools for many children and families. As charter schools proliferate across the United States, so does the number of school social workers employed by them. Even though school social work practice can vary widely across location, type of school setting, state educational policies, and contractual mandates, there is minimal research and limited information about school social work practices in charter schools. This article examines social work practice in the context of charter schools to provide charter school social workers with insight and information tailored to their unique school settings. The article will also review the history of the charter school movement and the impact of current charter school policies on social worker roles and interventions. Suggestions for future research are also discussed.
