Abstract
In this work, we synthesized colloidal silica nanospheres with an average size of 400 nm through the modified Stöber method and successfully fabricated an ordered close-packed silica nanosphere monolayer onto ITO-coated glass substrates using a three-step spin-coating method. ITO films showed resistivity comparable to that of commercial ITO and the silica nanosphere monolayer-coated ITO/glass substrate exhibited good optical transmittance in the visible (550 nm) and near-infrared (900 nm) regions of 62% and 82%, respectively. The results suggest that this monolayer can be used in optoelectronic devices to enhance efficiency in photovoltaic cells.

Abstract
Near-field radiative heat transfer (NFRHT) governed by evanescent waves, provides a platform to thoroughly understand the transport behavior of nonradiative photons, and also has great potential in high-efficiency energy harvesting and thermal management at the nanoscale. It is more usual in nature that objects participate in heat transfer process in many-body form rather than the frequently-considered two-body scenarios, and the inborn mutual interactions among objects are important to be understood and utilized for practical applications. The last decade has witnessed considerable achievements on many-body NFRHT, ranging from the establishment of different calculation methods to various unprecedented heat transport phenomena that are distinct from two-body systems. In this invited review, we introduce concisely the basic physics of NFRHT, lay out various theoretical methods to deal with many-body NFRHT, and highlight unique functionalities realized in many-body systems and the resulting applications. At last, the key challenges and opportunities of many-body NFRHT in terms of fundamental physics, experimental validations, and potential applications are outlined and discussed.

Published: February 2021

Abstract
Copper-stabilized second generation high-temperature superconductor (HTS) coated conductors were modified to enhance their normal zone propagation velocity (NZPV). Experimental results, supported by numerical simulations, indicate that adding copper on the substrate side instead of adding it on the HTS side increases the NZPV by a factor of 2–3. Furthermore, a novel tape architecture, called hybrid-current flow diverter (CFD), was investigated. This hybrid-CFD tape was designed with the goal of having a very long current transfer length, which is the key to enhance the NZPV. Results show that it is possible to fabricate an HTS tape with double stabilizer thickness in comparison to a bare tape, while accelerating the NZPV by a factor of three. With the same approach, a ten-fold increase of the NZPV can be expected for a tape with a 40 µm thick copper-stabilizer.
Comparison between SOLPS-4.3 and the Lengyel Model for ITER baseline neon-seeded plasmas
Authors: Moulton D. , Stangeby P.C. , Bonnin X. , Pitts R.A. 
Published: February 2021

Abstract
If correct, the Lengyel model offers a simple and powerful tool to predict the conditions required for detachment onset in future fusion reactors. We assess its validity against a comprehensive SOLPS-4.3 simulation database of ITER baseline (Q = 10) neon-seeded plasmas (Pacher et al 2015 J. Nucl. Mater. 463 591). In absolute terms, the Lengyel Model is found to significantly overpredict the simulated impurity concentration required in the ITER outer divertor for outer target ion flux rollover (by a factor ∼4.3 in this particular case). Importantly though, at detachment onset, and even beyond onset, the Lengyel model does give a remarkably accurate prediction of the scaling interdependencies between the electron density at the outer divertor entrance, the parallel energy flux density at the outer divertor entrance, and the impurity concentration in the outer divertor. However, the generalisation of these two key results to other machines, and in the presence of additional physics not included in these simulations, requires further studies. The analysis techniques described here provide a framework for such studies. Regarding the factor ∼4.3 overprediction of the simulated outer divertor impurity concentration, the main contributors to the disagreement are found to be other energy loss mechanisms besides impurity cooling (primarily neutral losses and radial transport) combined with convective energy fluxes near the target, as well as non-constant electron static pressure due to poloidally variable T
i/T
e. None of these are included in the Lengyel model. By themselves, these do not strongly influence the scaling interdependencies of the main Lengyel parameters over the explored parameter range. The impurity residence time τ is observed to increase with density, which tends to flatten out the impurity concentration scaling at low density, relative to the Lengyel model (which usually assumes constant τ). In these simulations, however, this flattening out was cancelled by an accumulation of other effects, so that the scaling prediction of the Lengyel model was still well met. A simple physics model is derived for n
e
τ that matches the simulation data well. Neon is found to migrate from the inner divertor to the outer divertor with increased puffing, thereby increasing the outer divertor neon enrichment. At outer target ion flux rollover, though, the enrichment is approximately independent of the upstream concentration, so that the Lengyel model predicts well the scaling dependency between the upstream impurity concentration and the upstream electron density, both key quantities dictating the operational range of a tokamak.

Published: February 2021

Abstract
The ability of a muon telescope to detect high dense metal elements was experimentally determined in previous works. Recently, the muon absorption has become one of the most important data in the tomography technique. In the present study, the absorption coefficients of muon at ground level for heavy alloys, namely brass, steel and stainless steel have been successfully recorded. The experiment was performed in Bangi, Malaysia with coordinates of 101.78º E, 2.92º N and elevation of 30 m above sea level. Muon examination was made by muon telescopes contained of two Geiger-Muller detectors. The muon count rate graphs showed an initial increase, followed by a transition depth and then a decrease with the continuous increase of the alloys thickness. The transition points observed were reliable and consistent with the properties of the alloys. The absorption coefficient of brass was higher than the other alloys; therefore, brass could be detected by cosmic ray muons easily. The results confirmed that the larger the mass density of the alloy absorber, the higher the ability to absorb the muon. The attenuation stated by this experiment would be valuable for coming work on muon revealing procedures.

AbstractWe analyzed solar burst type III occurred on 15th of May 2017 and compare with optical and X-ray region using the high time resolution hard-X-ray data from space weather and 10 MHz-120 MHz dynamic spectra from CALLISTO network. The eruption mechanism of solar flares and type III has been observed intermittently in the last a few hours since 10:00 UT. The burst consequences from the ejection of plasma oscillations localized disturbance due to excited in the plasma frequency incoherent radiations such as gyro synchrotron and free–free emissions. Significant results of the flaring becoming more intense at 10:05 UT. During this event, the electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 73 sfu. Solar wind speed reached a peak of 375 km/s at 14/2246Z. Total IMF reached 6 nT at 14/2123Z. It was found that radiation from the flare created waves of ionization in the upper atmosphere over Asia and Australia and possibly HF radio blackouts at high latitudes. We believed these data represent the first direct evidence of high-speed flows will be exploded on 20th April 2017 due to this pattern of eruption.

Published: February 2021

Abstract
Magnetic Data Acquisition System (MAGDAS) is a system of a real-time magnetometer data logger deployed by Kyushu Sangyo University of Fukuoka, Japan as part of Japan’s leading contribution to International Heliophysical year of the United Nations. This paper proposed a cloud-based MAGDAS for the YU-8T magnetometer. MAGDAS is the system that measures and monitors the earth’s magnetic field or geomagnetic field. Converting the old system to the new system will provide the capability to monitor the magnetic field changes continuously due to the solar activities which are harmful to the electrical appliances. To verify the workability of the system, the data from the MAGDAS Langkawi and solar event was gathered to be compared with the developed system. The location where the measurement takes place is at Pusat Sukan UiTM Shah Alam, Selangor, Malaysia (geographic latitude and longitude: 3.00N, 101.00E, and geomagnetic latitude and longitude: 6.37S, 173.65E. This project consists of the YU-8T magnetometer system, hardware, software, and cloud-based web-server. YU-8T magnetometer measures the voltage of Earth’s magnetic field in the form of H, D and Z parameters to be stored in the data logger. The stored data was transferred to the cloud-based web-server through the Internet of Thing (IoT) for real-time monitoring.

Published: February 2021

Abstract
Fatigue life is one of the most important characteristics of materials. Predicting fatigue life in magnetorheological elastomer (MRE) under combined and repetitive loads is an unavoidable step to increase the safety coefficient of MREs. In this study, high-temperature vulcanization silicon rubber (HTVSR) based MREs were fabricated by incorporating the different soft carbonyl iron particles (CIP) that samples with 10%, 20%, and 30% of CIP volume were made. Fatigue behavior of MRE under the combination of compression-tension and torsion loading in the presence and absence of magnetic fields was studied by using the multiaxial fatigue testing machine. The relationship between maximum energy density function (W
max) and fatigue life (N) was achieved that it can predict fatigue life in MREs. The results showed that the dissipation energy was smaller in the presence of a magnetic field at the same CIP volume percentage and increased as the CIP volume percentages grew, because the agglomeration in the samples became more. And also with a magnetic field, at the same CIP volume percentages, the strength of the MRE increased that led to the fatigue life of MRE increasing.

Published: February 2021

Abstract
Molecular exchange processes in organic heterostructures are often detrimental to the performance of nano-optoelectronic devices. Bilayers of vacuum sublimed organic semiconductors on inorganic substrates can serve as reductionist model for organic–organic interfaces and the coupling strength of the template layer on the substrate is a decisive factor for possible molecular exchange. We use density-functional theory modelling and x-ray photoelectron spectroscopy to show that the coupling of the pentacene oxo-derivatives 6,13-pentacenequinone (P2O) and 5,7,12,14-pentacenetetrone (P4O) with Au(111) is weak. Consequently, as shown by ultraviolet photoelectron spectroscopy, subsequently deposited copper-phthalocyanine (CuPc) diffuses through the template layers to the Au(111) substrate.

Abstract
There are few if any reports regarding the role of lifetime waterpipe smoking in the etiology of multiple sclerosis (MS). In a population-based incident case-control study conducted in Tehran, Iran, we investigated the association between waterpipe smoking and MS, adjusted for confounders. Cases (n = 547) were patients aged 15–50 years identified from the Iranian Multiple Sclerosis Society between 2013 and 2015. Population-based controls (n = 1,057) were persons aged 15–50 years recruited through random digit telephone dialing. A doubly robust estimation method, the targeted maximum likelihood estimator (TMLE), was used to estimate the marginal risk ratio and odds ratio for the association between waterpipe smoking and MS. The estimated risk ratio and odds ratio were both 1.70 (95% confidence interval: 1.34, 2.17). The population attributable fraction was 21.4% (95% confidence interval: 4.0, 38.8). Subject to the limitations of case-control studies in interpreting associations causally, these results suggest that waterpipe use, or strongly related but undetermined factors, increases the risk of MS. Further epidemiologic studies, including nested case-control studies, are needed to confirm these findings.

AbstractSuicide remains the leading cause of death among homeless youth. We assessed differences in health-care utilization between homeless and nonhomeless youth presenting to the emergency department or hospital after a suicide attempt. New York Statewide Inpatient and Emergency Department Databases (2009–2014) were used to identify homeless and nonhomeless youth aged 10–17 who utilized health-care services following a suicide attempt. To evaluate associations with homelessness, we used logistic regression models for use of violent means, intensive care unit utilization, log-transformed linear regression models for hospitalization cost, and negative binomial regression models for length of stay. All models adjusted for individual characteristics with a hospital random effect and year fixed effect. We identified 18,026 suicide attempts with health-care utilization rates of 347.2 (95% confidence interval (CI): 317.5, 377.0) and 67.3 (95% CI: 66.3, 68.3) per 100,000 person-years for homeless and nonhomeless youth, respectively. Length of stay for homeless youth was statistically longer than that for nonhomeless youth (incidence rate ratio = 1.53, 95% CI: 1.32, 1.77). All homeless youth who visited the emergency department after a suicide attempt were subsequently hospitalized. This could suggest a higher acuity upon presentation among homeless youth compared with nonhomeless youth. Interventions tailored to homeless youth should be developed.
Five-Year Safety and Satisfaction With the Lightweight Breast Implant
Authors: Orel Govrin-Yehudain , Noam Calderon , Jacky Govrin-Yehudain 
Published: February 2021

Abstract

Background
The B-Lite lightweight breast implant (LWBI) weighs approximately 30% less than traditional silicone implants while maintaining an equivalent size, form, and function. The LWBI thus places less stress on breast tissues and preserves tissue stability and integrity over time, reducing weight-related complications and reoperation rates.

Objectives
The authors sought to assess the long-term (&gt;5 years) safety and performance of the LWBI in primary and revision augmentation procedures.

Methods
A retrospective, single-center, single surgeon analysis of prospectively collected data was performed on 827 consecutive primary and revision augmentation patients operated between December 2013 and January 2019. A total 1653 implants (250-835 cc, mostly round, textured, extra high-profile) were implanted employing standard surgical techniques. Direct physician-to-patient follow-up ranged from 6 to 67 months. Chart data on reoperations and overall complications as well as patient and surgeon satisfaction were analyzed.

Results
The 5-year per patient Kaplan–Meier reoperation free rate was very high (97.1%). Only 2 of 5 total cases of capsular contracture (CC) grade III required reoperation (Kaplan–Meier rate = 0.2%, CI = 0.1–1.0). No cases of rupture or breast implant-associated anaplastic large cell lymphoma were recorded. A total 94.9% of patients rated the aesthetic outcome, and 95.5% of patients rated the natural look and feel of their breasts at 4 to 5 (satisfied-very satisfied). Similarly, the surgeon rated 4 to 5 on 95.4% of the patients’ aesthetic outcomes.

Conclusions
The favorable safety profile, high patient and surgeon satisfaction, and inherent benefits of reduced weight should make the LWBI a strongly considered strategic alternative to traditional implants.

Published: February 2021

AbstractThis article reports on a quantitative study of how Canadian social work educators engage in social policy practice. The first part of the article contextualises social policy in Canada, explains how social policy has been incorporated into Canadian social work education and concludes by posing the research question. The second part presents the study’s findings of how and to what extent Canadian social work academics engage with social policy including its development, analysis and implementation. Thirty-one educators representing seventeen of Canada’s forty schools of social work responded to a standard questionnaire used in a collection of cross-national studies. The Canadian responses were analysed to determine (1) the level and type of engagement in policy including the perceived impact on social policy and (2) the institutional and individual factors associated with their engagement. Some comparisons are made with other countries studies. The third part of the article provides overall concluding comments linking the first part with the findings of the second, speculates on the reasons for some of the findings and poses some ideas for future research. Finally, it laments the increased focus of Canadian social work on individual pathology.

AbstractA close interaction between gut immune responses and distant organ-specific autoimmunity including the CNS in multiple sclerosis has been established in recent years. This so-called gut–CNS axis can be shaped by dietary factors, either directly or via indirect modulation of the gut microbiome and its metabolites. Here, we report that dietary supplementation with conjugated linoleic acid, a mixture of linoleic acid isomers, ameliorates CNS autoimmunity in a spontaneous mouse model of multiple sclerosis, accompanied by an attenuation of intestinal barrier dysfunction and inflammation as well as an increase in intestinal myeloid-derived suppressor-like cells. Protective effects of dietary supplementation with conjugated linoleic acid were not abrogated upon microbiota eradication, indicating that the microbiome is dispensable for these conjugated linoleic acid-mediated effects. Instead, we observed a range of direct anti-inflammatory effects of conjugated linoleic acid on murine myeloid cells including an enhanced IL10 production and the capacity to suppress T-cell proliferation. Finally, in a human pilot study in patients with multiple sclerosis (n = 15, under first-line disease-modifying treatment), dietary conjugated linoleic acid-supplementation for 6 months significantly enhanced the anti-inflammatory profiles as well as functional signatures of circulating myeloid cells. Together, our results identify conjugated linoleic acid as a potent modulator of the gut–CNS axis by targeting myeloid cells in the intestine, which in turn control encephalitogenic T-cell responses.
