We investigate structural and transport properties of highly Ru-deficient SrRu0.7O3 thin films prepared by molecular beam epitaxy on (001) SrTiO3 substrates. To distinguish the influence of the two types of disorders in the films—Ru vacancies within lattices and disorders near the interface—SrRu0.7O3 thin films with various thicknesses (t = 1–60 nm) were prepared. It was found that the influence of the former dominates the electrical and magnetic properties when t ≥ 5–10 nm while that of the latter does when t ≤ 5–10 nm. Structural characterizations revealed that the crystallinity, in terms of the Sr and O sublattices, of SrRu0.7O3 thin films is as high as that of the ultrahigh-quality SrRuO3 ones. The Curie temperature (TC) analysis elucidated that SrRu0.7O3 (TC ≈ 140 K) is a material distinct from SrRuO3 (TC ≈ 150 K). Despite the large Ru deficiency (∼30%), the SrRu0.7O3 films showed metallic conduction when t ≥ 5 nm. In high-field magnetoresistance measurements, the fascinating phenomenon of Weyl fermion transport was not observed for the SrRu0.7O3 thin films irrespective of thickness, which is in contrast to the stoichiometric SrRuO3 films. The (magneto)transport properties suggest that a picture of carrier scattering due to the Ru vacancies is appropriate for SrRu0.7O3 and also that proper stoichiometry control is a prerequisite to utilizing the full potential of SrRuO3 as a magnetic Weyl semimetal and two-dimensional spin-polarized system. Nevertheless, the large tolerance in Ru composition (∼30%) to metallic conduction is advantageous for some practical applications where SrRu1−xO3 is used as an epitaxial conducting layer.

Significance
Aggregation and cell-to-cell spread of TDP-43 are thought to underlie many cases of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). Additionally, the aging process and environmental toxins stimulate excessive generation of reactive oxygen and nitrogen species (ROS/RNS), thus contributing to the pathological processes of these neurodegenerative diseases. Here, we show that nitric oxide (NO)-related species promote TDP-43 proteinopathy in cell-based and animal models of FTD/ALS via S-nitrosylation of TDP-43 at critical cysteine residues that facilitate disulfide bond formation and abnormal aggregation of the protein. In contrast, expression of nonnitrosylatable mutant TDP-43 ameliorates TDP-43 aggregation, RNA binding, and cell toxicity. Thus, our study provides mechanistic insight into the ROS/RNS-induced TDP-43 proteinopathy and neurotoxicity observed in FTD/ALS patients.

Abstract

Objectives
Alcohol intake and smoking are modifiable lifestyle-related risk factors for osteonecrosis of the femoral head (ONFH). We investigated geographic differences in ONFH incidence in Japan and the correlation with alcohol intake and smoking to develop prevention strategies for ONFH in Japan.

Methods
This ecological study was conducted in Japan primarily using the following data sources: nationwide epidemiological survey and national survey. We estimated the annual ONFH incidence and the prevalence of alcohol drinking and smoking in each prefecture. Prefectural incidence and prevalence were calculated by sex and age-standardization.

Results
The mean annual ONFH incidence per 100,000 population was 3.08 in men and 1.63 in women, respectively. There was no significant correlation between ONFH incidence and the prevalence of any levels of alcohol intake, while smoking ≥20 cigarettes/day showed a significant and moderate correlation in men (r = 0.47, p = .01). This correlation remained significant after adjustment for the prevalence of any levels of alcohol intake (standardized partial regression coefficient = 0.47–0.49, p = .009–.01).

Conclusion
ONFH incidence is geographically variable in Japan, and this may be partly explained by the distribution of smoking prevalence. Smoking cessation may contribute to an effective decline in the overall ONFH incidence in Japan.
RG-2 flow and black hole entanglement entropy
Authors: Andino Oscar Lasso 
Published: March 2021

Abstract
We study the evolution of a Euclidean two-dimensional black hole metric under the second loop renormalization group flow, the RG-2 flow. Since the black hole metric is non-compact (we consider it asymptotically flat) we adapt some proofs for the compact case to the asymptotically flat case. We found that the appearance of horizons during the evolution is related to the parabolicity condition of the flow. We also show that the entanglement entropy of the two-dimensional Euclidean Schwarzschild black hole is monotonic under the RG-2 flow. We generalize the results obtained for the first loop approximation and discuss the implications for higher order loops

Abstract
A dual-pass differential Fabry–Perot interferometer (DPDFPI) is one candidate of the interferometer configurations utilized in future Fabry–Perot type space gravitational wave antennas, such as Deci-hertz Interferometer Gravitational wave Observatory. In this paper, the working principle of the DPDFPI has been investigated and necessity to adjust the absolute length of the cavity for the operation of the DPDFPI has been found. In addition, using the 55 cm-long prototype, the operation of the DPDFPI has been demonstrated for the first time and it has been confirmed that the adjustment of the absolute arm length reduces the cavity detuning as expected. This work provides the proof of concept of the DPDFPI for application to the future Fabry–Perot type space gravitational wave antennas.

Abstract
In this study, comparisons of spatiotemporal resolved images, optical emission spectroscopy technology, and electrical characteristics diagnosis were used to investigate the conversion and optimization of the discharge modes in a packed bed reactor (PBR) in which dielectric materials with different dielectric constants were employed under different peak voltages. The effects of the peak voltages and dielectric materials on the production of reactive species, such as

, were also studied for plasma applications. The results show that, when a polytetrafluoroethylene (PTFE) column is employed, with an increase in the peak voltages, the form and modes of the discharge both change. First, the discharge channel becomes ‘wider’ and the discharge volume becomes larger, which results in more reactive species. Second, the discharge mode changes from surface discharge to diffuse discharge during the falling edge of the voltage pulse. When the dielectric constant of the dielectric material is increased, the intensity of the surface streamer decreases during its shorter propagation path because of more electron collision losses. Moreover, a different discharge mode, called ‘local discharge’, was observed at the contact point. Under the same experimental conditions, the numbers of nitrogen molecules distributed at different vibrational levels and the reactive species produced in the alumina PBR were fewer than those in the PTFE PBR.

Published: March 2021

AbstractHerein, we fabricated CdSe-based thin-film transistors (TFTs) employing two different hybrid dielectric gates, SiO2–poly(vinylphenol) and Al2O3–3-glycidoxypropyltrimethoxysilane–polymethylmethacrylate. These organic–inorganic hybrid dielectric layers were processed by the sol-gel method at low temperatures (<200 °C), and the CdSe semiconductor layer was deposited by R.F sputtering at room temperature. The chemical and physical properties of the hybrid thin films were thoroughly evaluated by Fourier transform infrared spectroscopy, field emission scanning electron microscope, atomic force microscopy and surface energy analysis. The results have shown an adequate interaction between both organic and inorganic phases in the hybrid material and the obtained hybrid thin films are very homogeneous with low surface roughness. Further, the dielectric properties of these hybrid thin films showed salient features with similar leakage currents for both dielectrics of the order of 10−6A cm−2, and dielectric constants of 7 and 11 at 1 kHz for the silica and alumina based dielectrics, respectively. The higher dielectric constant of the alumina hybrid dielectric is associated to excessive oxygen defects such as hydroxyl groups (OH) and oxygen vacancies (Vo), which produce high dielectric loss through hopping relaxation. To investigate the feasibility of these two hybrids as dielectric gate layers we constructed TFTs with CdSe as active channel layer. Among these, TFTs fabricated with silica hybrid dielectric showed the best performance with a current off/on ratio of 104, threshold voltage of 1.1 V and mobility of 22.2 cm2V−1s−1. Meanwhile, the TFT device with alumina hybrid as dielectric gate layer exhibited a diminished electrical performance in terms of lower mobilities, which is mostly related to the defects at the dielectric/semiconductor interface. These defects manifested as well in the capacitance measurements of the alumina hybrid dielectric and have a strong influence on the device mobility since the charge carriers traps restrict the electrical transport in the semiconductor channel.

Abstract
The development of safe and efficient nanocomposites remains a huge challenge in targeted therapy of glioma. Nanostructured lipid carriers (NLCs), which facilitate specific site drug delivery, have been widely used in glioma treatment. Herein, we aimed to investigate the underlying mechanisms and therapeutic impact of paclitaxel (PTX) and doxorubicin (DOX) loaded NLC (PTX-DOX-NLC) on glioma stem cells (GSCs). To this end, we used a melt-emulsification technique to generate PTX loaded NLC (PTX-NLC), DOX loaded NLC (DOX-NLC), and NLC loaded with both drugs (PTX-DOX-NLC). We firstly confirmed the stability of PTX-DOX-NLC and their ability to gradually release PTX and DOX. Next, we evaluated the effects of PTX-DOX-NLC on apoptosis and proliferation of GSCs by flow cytometry and CellTiter-Glo assay. Besides, the expression of relevant mRNA and proteins was determined by RT-qPCR and Western blot analysis, respectively. Mechanism of action of PTX-DOX-NLC was determined though bioinformatic analysis based on RNA-seq data performed in GSCs derived from different NLC-treated groups. In addition, a mouse xenograft model of glioma was established to evaluate the anti-tumor effects of PTX-DOX-NLC in vivo. Results indicated thar PTX-DOX-NLC showed greater inhibitory effects on proliferation and promotive effects on apoptosis of GSCs compared with PTX-NLC, DOX-NLC, free PTX, and free DOX treatment. Mechanistic investigations evidenced that PTX-DOX-NLC inhibited tumor progression by suppressing the PI3K/AKT/mTOR signaling in vitro and in vivo. Taken together, PTX-DOX-NLC played an inhibitory role in GSC growth, highlighting a potential therapeutic option against glioma.
A cooperative game solution approach for intensity modulated radiation therapy design: Nash Social Welfare optimization
Authors: Saghand Payman Ghasemi , Charkhgard Hadi 
Published: March 2021

Abstract
We study the fluency map optimization problem in Intensity Modulated Radiation Therapy from a cooperative game theory point of view. We consider the cancerous and healthy organs in a patient’s body as players of a game, where cancerous organs seek to eliminate the cancerous cells and healthy organs seek to receive no harm. The goal is to balance the trade-offs between the utility of players by forming a grand coalition between them. We do so by proposing a methodology that solves a few convex optimization problems in order to transform the fluency map optimization problem into a bargaining game. To solve the bargaining game, we employ the concept of Nash Social Welfare (NSW) optimization due to the desirable efficiency and fairness properties of its outcomes. The proposed NSW optimization is convex and can be solved by powerful commercial solvers such as CPLEX. An additional advantage of the proposed approach is that it has a new control lever for the fluency map optimization, the so-called negotiation powers, which enables practitioners to put more emphasis on an organ by changing its negotiation power. To show the efficacy of our proposed methodology, we apply it to the TG-119 case and a liver case. We compare our proposed approach with a state-of-the-art approach through creating Dose Volume Histograms.
A short review of loop quantum gravity
Authors: Ashtekar Abhay , Bianchi Eugenio 
Published: March 2021

AbstractAn outstanding open issue in our quest for physics beyond Einstein is the unification of general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading approach toward this goal. At its heart is the central lesson of GR: gravity is a manifestation of spacetime geometry. Thus, the approach emphasizes the quantum nature of geometry and focuses on its implications in extreme regimes—near the big bang and inside black holes—where Einstein’s smooth continuum breaks down. We present a brief overview of the main ideas underlying LQG and highlight a few recent advances. This report is addressed to non-experts.
Very thin (111) NiO epitaxial films grown on c-sapphire substrates by pulsed laser deposition technique
Authors: Yadav Santosh Kumar , Dhar Subhabrata 
Published: March 2021

Abstract
(111) NiO epitaxial layers are grown on c-sapphire substrates by pulsed laser deposition technique. Structural and morphological properties of the films are studied using in-plane as well as out-of-plane high resolution x-ray diffraction and atomic force microscopy techniques as functions of growth temperature, oxygen pressure and the pulses count of the laser. The study shows that continuous epitaxial films of thickness as low as 3 nm with high crystalline quality, smooth surface and interface morphology can be grown by this technique. The study also reveals the co-existence of 60°-rotated (111) triangular domains of NiO in the film. The study also evidences the presence of a very low density of 60° dislocations in these films. Density of screw and edge dislocations are also estimated to be quite low. It has been found that growth-temperature, oxygen partial pressure and the film thickness can influence differently the density of various dislocation types. These parameters are also found to affect significantly the strain developed in the films.

Published: March 2021

Abstract
In the present report, silica capped ZnS quantum dots (QDs) have been synthesized using one-step Stober process. The bare Mn doped ZnS samples have been prepared by the co-precipitation method. The samples have then been coated by a SiO2 layer. X ray diffraction have been used to confirm the presence of desired phases and the absence of any impurity phase. The particle size and morphology have been studied through high resolution transmission electron microscopy (HRTEM). The absorption and the emission properties of the bare and the capped samples have been studied through UV-visible and photoluminescence spectroscopy respectively. Fourier-transform infrared (FTIR) spectroscopy was employed to study the band resonances of the samples.

We investigate the gravitational wave production induced by
the primordial magnetic fields in a parity-violating magnetogenesis
model. It is shown that the gravitational waves detectable by LISA,
DECIGO or BBO and the magnetic fields strong enough to explain the
blazar observation can be simultaneously produced. The magnetic
fields and the gravitational waves have the same chirality and their
amplitudes are related, which may also be tested by future
observations.

Published: March 2021

Abstract
The accurate assessment of tritium breeding parameters within fusion blankets is crucial for future magnet-confined fusion machines to realize fuel self-sufficiency. Such an assessment can be conducted using the simulation approach with nuclear data of high-fidelity and, most importantly, validated against experimental data. In this paper, we report neutronics experiment studies carried out on a mock-up of the water-cooled ceramic breeder blanket of the China fusion engineering test reactor (CFETR), irradiated at a deuterium–tritium (D–T) neutron source. The mock-up’s nuclear responses to 14 MeV neutrons, including tritium production rates (TPR) and neutron-induced reaction rates, are simulated and validated by experimental results. Redundant measurement techniques are used, including Li2TiO3 pellets for offline TPR measurements and the developed lithium glass detector with a significantly reduced size for online TPR measurements. The validation of the TPR value is complemented by the experimental evaluation of the neutron-induced reaction rates for Au and Zr foils. All experimental results are analyzed using the MCNP-4C code and FENDL-3.0 nuclear data library. The source term for the Monte Carlo simulation is built using a newly-developed method based upon the modeling of the depth profiling of tritium in the tritiated target. The experiments are in good agreement with the simulations; ratios of the calculation to experimental results (C/E) on TPR are found to be 0.97–1.08. The influence of the first wall tungsten armor on the mock-up nuclear responses is also studied.

Authors: Li Cai , Xiaoling Zhu 
Published: March 2021

Abstract
In practical engineering application, the response of mechanical structure may be the superposition effect of vibration source interaction, while the traditional detection method only considers the main vibration source, ignoring other vibration sources will cause analysis error. Therefore, it is of practical engineering significance to study the detection method of compound excitation in mechanical testing. This paper aims to present an extraction method of composite modulation signal under multi-source excitation by wavelet transform. The modulated signal is analyzed by short-time Fourier transform and wavelet transform. The time-frequency analysis results show that the resolution of wavelet can be automatically adjusted at high frequency, and the effect of wavelet is better at high frequency. The key contribution is to establish a method for extracting multi-source excitation signals and to provide certain technical support for the modulated signal under multi-source excitation.

Abstract
This paper presents a design method of airborne radar attitude test system based on servo drive, which can realize the closed-loop test of servo system, the separate test of antenna drive module, the separate test of scanner base and the attitude test. The system adopts the attitude angle measurement method based on fiber laser gyroscope as the core, which can realize scanning angle: azimuth ±0.2° and pitch. By decoupling the disturbance and the measured, the small angle attitude algorithm is designed and corrected.
