Authors: Sun Yifei , Zhang Yan , Xu Zhao , Gou Wenshan , Han Xuguang , Liu Mengmeng , Li Chang Ming 
Published: September 2022

AbstractA hybrid electrolyte based on low‐concentration sodium nitrate with glycerol as an additive was proposed for aqueous sodium‐ion batteries (ASIBs) towards low‐temperature performance. Based on this dilute hybrid electrolyte and configured by bimetallic Prussian blue analogue (Ni2ZnHCF) cathode and 3,4,9,10‐perylenetetracarboxylic diimide (PTCDI) anode, the full cell demonstrated surprising cycle performance with a specific capacity of 60 mAh g−1 (>800 cycles) and achieved prominent performance at low temperature. Glycerol effectively expanded the electrochemical stability window of the hybrid electrolyte to 2.7 V from formation of strong hydrogen bonds with water molecules and realized the operation of the cell at low temperature, delivering a stable reversible capacity of 40 mAh g−1 at −10 °C. The hybrid electrolyte of glycerol‐water provides a new alternative in development of low‐cost, long‐lifespan, and low‐temperature ASIBs and other aqueous battery systems.

Authors: Chen Sanxia , Xue Wenxuan , Tang Conghui 
Published: September 2022

AbstractAn easily prepared core‐shell heterogeneous nanocobalt catalyst was reported, which could achieve selective reduction of N‐heteroarenes with ammonia borane under mild conditions and ambient atmosphere. Various quinoline, quinoxaline, naphthyridine, isoquinoline, acridine, and phenanthroline derivatives were hydrogenated with high selectivity and efficiency. Notably, substrates bearing sensitive functional groups under molecular hydrogen reduction conditions, such as cyano, ester, and halogens were well tolerated by the catalytic system. Moreover, with our novel method several bioactive molecules were prepared. Also, this catalyst could be applied in the liquid organic hydrogen storage system by reversible hydrogenation and dehydrogenation of heteroarene in high efficiencies.
Finding ‘pockets of possibility’ for anti‐racism in a curriculum for student teachers: From absence to action
Authors: Smith Heather , Lander Vini 
Published: September 2022

AbstractMany institutions have found the strength to name racism and seek space for curriculum and other systemic changes. We argue this is happening against a backdrop of curriculum, regulatory and policy changes in education, and particularly initial teacher education and training (ITE/T), which are de‐racialised. We propose that a ‘pocket of possibility’ lies within such divergences, and present research leading to the creation of an anti‐racism framework for ITE/T to support action against this emergent landscape. The paper documents each aspect of the research and snapshots of the findings of a global literature review of anti‐racism in initial teacher education, which demonstrated the need for an embedded approach to anti‐racism, informed by critical understandings of whiteness and racism. We share some of the complexities, obstacles, and effective anti‐racism practices revealed in the review. The findings of the review led to the creation and analysis of a survey for ITE/T providers in England, which provided encouraging evidence of useful practice alongside needs of the profession. We conclude with a statement of intent and hope to maximise of the minimum entitlement of the Core Content Framework (CCF) by a purposeful undoing of the perpetual de‐racialisation of education.

Authors: Kim Yoonjung , Han Man‐Hoon , Kim Shin‐Woo , Won Dong Il 
Published: September 2022

AbstractBackgroundThe interferon‐γ(IFN‐γ) release assay (IGRA) is widely used to diagnose tuberculosis (TB) caused byMycobacterium tuberculosis(Mtb). However, indeterminate IGRA results due to “high Nil” or “low PHA” responses limit its clinical utility. We developed a novel assay using CD69 flow cytometry (FC) to complement IGRA.MethodsCD69 FC measures the surface CD69 expression on T cells prior to centrifugation to harvest the plasma for IGRA. T cell responses against Mtb antigen 1 (Ag1) or Ag2 were measured using three‐color FC (CD3, CD4, and CD69) in TB (n = 140) and non‐TB groups (n = 117). The cutoff values of Δ%CD69brightcells (stimulated minus unstimulated) for CD4+and CD4−T cells were established based on healthy individuals (n = 63). The assay performances of CD69 FC and IGRA were compared.ResultsIn subjects with determinate IGRA results (“positive” or “negative”; n = 216), the diagnostic accuracies of CD69 FC (90.3%) and IGRA (87.0%) were not significantly different (p = 0.31). For indeterminate IGRA results (n = 40), CD69 FC attained a diagnostic accuracy of 92.5%. The CD4+/CD4−ratio within CD69brightT cells measured by CD69 FC was significantly higher (p < 0.05) in the active TB group (6.39 ± 132.05; n = 72) than in other CD69 FC‐positive subjects (2.84 ± 15.36; n = 63) (p < 0.05), whereas CD8 responses expected by IGRA (difference of IFN‐γlevels between Mtb Ag tubes) did not differ significantly (0.00 ± 9.18 and 0.00 ± 4.25, respectively, IU/ml;p = 0.58).ConclusionsWe demonstrated the potential of CD69 FC as a simple, rapid assay for clarifying indeterminate IGRA results and identifying active TB. With further improvements, CD69 FC may complement the IGRA to enhance TB risk stratification in the routine diagnostic workup.
Dibenziodolium Salts as Halogen Bond Donor Catalysts for the Reduction of Quinolines, One‐Pot Reductive Amination, and Addition Reaction with Indoles
Authors: Nandy Anuradha , Sekar Govindasamy 
Published: September 2022

AbstractThe efficiency of dibenziodolium salts as halogen bond donor catalysts was investigated by studying various organic transformations. Diverse reactions were carried out with low catalytic loading and under mild conditions. The catalyst was found to be efficient for carrying out the reduction of quinolines, one‐pot reductive amination, Michael addition reaction of indoles with chalcones, and Friedel‐Crafts reaction of indoles with isatin with a low catalytic loading of 3 mol %. A wide substrate scope was attempted for all the transformations. Several control experiments were carried to rule out the possibility of hidden Brønsted acid catalysis. NMR studies and preliminary DFT calculations suggest the presence of halogen bond between the catalyst and the substrate.

Authors: Dhiman Abhishek , Sachdeva Gulshan 
Published: September 2022

AbstractIn the present research article, an indirect type solar cooking system has been developed for indoor cooking. In the proposed cooking system, a cooking pot has been placed at a distance of 5 m from the parabolic dish collector, and the heat has been transmitted from the collector to the cooking pot by means of heat transfer fluid. A gear pump of 40 W and insulated pipes have been used to circulate the fluid. A number of experiments have been performed to analyze the performance of the cooking system. During the investigation, the system achieved the temperature of the heat transfer fluid up to 175°C. The time taken for cooking the rice and the black grams has been observed 21 and 68min, respectively. The average thermal efficiency of the proposed system for the entire day has been achieved at 13.11%.

Published: September 2022

AbstractA special investigation on the heat transfer by applying viscous dissipation and considering the Newtonian heating condition in magnetohydrodynamic Powell–Eyring fluid has been attempted. It is regarded as the flow in an axisymmetrical direction over a radially stretching surface. The converted governing system of equations is solved to obtain a closed‐form solution using the Keller‐box technique. The skin‐friction coefficient's influence fully developed local Nusselt number is then presented graphically, and temperature profiles are sorted out for the pertinent parameters. The fluid overshoot towards the plate surface with rising magnetic field strength, hence, both the fluid velocity and the hydrodynamic border line layer thickness will fall, though, the skin‐friction coefficient will increase. Various relevant results of the energy indulgence have been discussed from heating and in view of viscous dissipation phenomena. The decision with minimal cases from previous studies in the literature received confirmation of the findings.
Environmental regulations and firm‐level FDI: Evidence from China's 11th 5‐year plan
Authors: Tan Yong , Shi Qing , Xuan Siyuan , Yang Guang 
Published: September 2022

AbstractThis paper investigates the influence of environmental regulations on outward foreign direct investment (OFDI). We first develop a simple model to show that an increase in emission tax in the domestic market induces firm‐level foreign direct investment (FDI) activities. We next take advantage of China's 11th Five‐Year Plan as a quasi‐natural experiment, which imposed different pollution reduction targets across provinces, and examine its impact on firm‐level FDI activities. Our results indicate that more stringent environmental regulations encourage firm‐level FDI participation. Furthermore, (1) firms are more likely to carry out FDI in developing countries instead of developed ones; (2) Compared with distribution‐oriented FDI, firms are more likely to engage in production‐oriented FDI. All results remain robust after controlling for possible policy endogeneity, missing variables, and expectation effect issues, which provides positive support for the pollution haven hypothesis.
The impact of China's Differential Electricity Pricing policy on fossil fuel consumption
Authors: Zhao Lin 
Published: September 2022

AbstractChina, the world's largest energy consumer, has been increasingly relying on pricing policies to improve energy efficiency in recent years. This paper estimates the impact of Differential Electricity Pricing (DEP) policy, which covers the most energy‐intensive industries in China. Under the DEP policy, electricity surcharges are imposed on enterprises using “eliminated” and “restricted” production technologies, of which the “eliminated” enterprises are more backward in technology level and are charged much higher electricity tariffs. We exploit a differences‐in‐differences approach to assess the effect of the DEP policy on fossil fuel consumption. The results indicate that the DEP policy led to a reduction in coal consumption intensity (CCI) of “eliminated” enterprises, which can be explained by the obsoleting of backward equipment in these enterprises. As for the “restricted” enterprises, it was economically optimal to continue to use “restricted” equipment; consequently, the DEP policy had no significant impact on CCI.

Published: September 2022

AbstractIt is well known that hyperglycemia leads to the progression and expansion of various micro and macrovascular disease such as diabetic nephropathy (DN). Lycoperoside H (LH) alkaloidal saponin exhibited the antidiabetic effect, but its DN effect is unclear. In this experimental study, we scrutinized the renal protective effect of LH against the streptozotocin (STZ)‐induced DN in rats and explore the underlying mechanism. Sprague–Dawley rats were used in this experimental study and an intraperitoneal injection of STZ (45 mg/kg) was used for the induction of diabetes, rats received the oral administration of LH (20 mg/kg). The blood glucose level, body weight, organ weight (renal and pancreas), and biochemical parameters were estimated. We also scrutinized the effect of LH to enhance intestinal barrier function and suppress inflammation and intestinal permeability. LH significantly (p < 0.001) decreased the glucose level and enhanced the body weight with a reduction of renal weight and boost the pancreas weight. LH significantly (p < 0.001) enhanced the creatinine level and decreased the albumin level, urine volume, urinary albumin excretion rate, and urinary albumin creatinine ratio in the urine. It also suppressed the renal parameters, such as creatinine, blood urea nitrogen, and urea. LH significantly (p < 0.001) altered the level of lipid and antioxidant parameters. LH treatment significantly (p < 0.001) suppressed the cytokines and inflammatory parameters. LH considerably enhanced the Ruminococcaceae, Blautia, and suppressed the abundance of Bifidobacterium, Clostridium, and Turicibacter. It reduced the F/B ratio along with alteration of community abundance of Firmicutes, Actinobacteria, Proteobacteria, Tenericutes, other bacteria, and Bacteroidetes. The current result suggests that LH suppressed the diabetic nephropathological condition via alteration of gut microbiota and inflammation.

AbstractObjectiveThe present study was designed to examine distinct co‐occurrence patterns of acculturation and perceived context of reception between weekdays and weekends among Hispanic college students in Miami and their influences on psychosocial maladaptation.MethodsWe conducted a 12‐day diary study with a sample of first‐ and second‐generation Hispanic college students in Miami (n = 864). Depressive symptoms and physically aggressive behaviors were assessed on Days 1 and 12, and acculturation components and perceived negative context of reception were measured using single items on Days 2–11. We examined the overlap between weekday and weekend patterns of acculturation and negative context of reception, as well as links of this overlap with depressive symptoms and with physically aggressive behaviors.ResultsOverall, six distinct co‐occurrence patterns of acculturation and perceived contexts of reception emerged from the analysis. Four of these appeared to represent stable co‐occurrence patterns regardless of weekdays and weekends and two indicated changing co‐occurrence patterns between weekdays and weekends. Students in patterns of the Moderate Biculturalism–High Negative Context of Reception regardless of weekdays and weekends reported high depressive symptoms and physically aggressive behaviors. Also, for the two changing co‐occurrence patterns, students in patterns of the Changes in both Acculturation and Negative Context of Reception between weekdays and weekends reported high scores on both depressive symptoms and physical aggressive behaviors.ConclusionBoth stable and changing patterns in acculturation and context of reception co‐occurrences between weekdays and weekends predicted psychosocial maladaptation.
Influence of vanadium addition on corrosion behavior of high‐energy ball milled aluminum alloy 2024
Authors: Ozdemir Furkan , Gupta Rajeev K. 
Published: September 2022

AbstractThe effect of V addition on the hardness and corrosion of aluminum alloy 2024 (AA2024) produced by high‐energy ball milling has been investigated. High‐energy ball milled alloys exhibited enhanced solid solubility of alloying elements and ultrafine grains. The addition of V improved the corrosion resistance of the AA2024 alloy, which was attributed to the deposition of V on the cathodic particles and therefore decrease in their ability to sustain large cathodic currents.
Lentiviral vector transduction provides nonspecific immunogenicity for syngeneic tumor models

Published: September 2022

AbstractLentivirus‐based transduction systems are widely used in biological science and cancer biology, including cancer immunotherapy. However, in in vivo transplanted tumor model, the immunogenicity of these transduced cells was not appropriately addressed. Here, we used empty vector‐transduced mouse melanoma (B16) and carcinoma (lewis lung carcinoma) cells transplanted tumor model to study the immune response due to the transduction processes. We showed that the overall in vivo tumor growth rate gets reduced in transduced cells only in immune‐competent mice but not in nude mice. This data indicate the involvement of the immune system in the in vivo tumor growth restriction in the transduced group. Further studies showed that specific activation of CD8+ T cells might be responsible for restricted tumor growth. Mechanistically, transduced tumor cells show the higher activity of type I interferon, which might play an essential role in this activation. Overall, our data indicate the modulation of the immune system by lentiviral vector transduced tumor cells, which required further studies to explore the mechanisms and better understand the biological significance. Our data also indicate the importance of considering the immunogenicity of transduced cells when analyzing in vivo results, especially in studies related to immunotherapy.

Published: September 2022

AbstractThe severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) pandemic resulted in significant societal costs. Hence, an in‐depth understanding of SARS‐CoV‐2 virus mutation and its evolution will help determine the direction of the COVID‐19 pandemic. In this study, we identified 296,728 de novo mutations in more than 2,800,000 high‐quality SARS‐CoV‐2 genomes. All possible factors affecting the mutation frequency of SARS‐CoV‐2 in human hosts were analyzed, including zinc finger antiviral proteins, sequence context, amino acid change, and translation efficiency. As a result, we proposed that when adenine (A) and tyrosine (T) bases are in the context of AM (M stands for adenine or cytosine) or TA motif, A or T base has lower mutation frequency. Furthermore, we hypothesized that translation efficiency can affect the mutation frequency of the third position of the codon by the selection, which explains why SARS‐CoV‐2 prefers AT3 codons usage. In addition, we found a host‐specific asymmetric dinucleotide mutation frequency in the SARS‐CoV‐2 genome, which provides a new basis for determining the origin of the SARS‐CoV‐2. Finally, we summarize all possible factors affecting mutation frequency and provide insights into the mutation characteristics and evolutionary trends of SARS‐CoV‐2.

Published: September 2022

PurposeTo calculate temperatures from T2*‐weighted images collected during optogenetic fMRI based on proton resonance frequency (PRF) shift thermometry, to monitor confounding heating effects and determine appropriate light parameters for optogenetic stimulation.MethodsfMRI is mainly based on long‐TE gradient‐recalled echo acquisitions that are also suitable for measuring small temperature changes via the PRF shift. A motion‐ and respiration‐robust processing pipeline was developed to calculate temperature changes based on the PRF shift directly from the T2*‐weighted images collected for fMRI with a two‐shot 2D gradient‐recalled echo‐EPI sequence at 9.4T. Optogenetic fMRI protocols which differed in stimulation durations (3, 6 and 9 s) within a total block duration of 30 s were applied in a squirrel monkey to validate the methods with blue and green light (20 Hz, 30 mW) delivery interleaved between periods. General linear modeling was performed on the resulting time series temperature maps to verify if light delivery with each protocol resulted in significant heating in the brain around the optical fiber.ResultsThe temperature SD was 0.05°C with the proposed imaging protocol and processing. Statistical analysis showed that the optogenetic stimulation protocol with a 3 s stimulation duration did not result in significant temperature rises. Significant temperature rises up to 0.13°C (p < 0. 05) were observed with 6 and 9 s stimulation durations for blue and green light.ConclusionThe proposed processing pipeline can be useful for the design of optogenetic stimulation protocols and for monitoring confounding heating effects.

PurposeTo explore a fetal 3D cardiovascular cine acquisition using a radial image acquisition and compressed‐sensing reconstruction and compare image quality and scan time with conventional multislice 2D imaging.MethodsVolumetric fetal cardiac data were acquired in 26 volunteers using a radial 3D balanced SSFP pulse sequence. Cardiac gating was performed using a Doppler ultrasound device. Images were reconstructed using a parallel‐imaging and compressed‐sensing algorithm. Multiplanar reformatting to standard cardiac views was performed before image analysis. Clinical 2D images were used for comparison. Qualitative and quantitative image evaluation were performed by two experienced observers (scale: 1–4). Volumes, mass, and function were assessed.ResultsAverage scan time for the 3D imaging was 6 min, including one localizer. A 2D imaging stack covering the entire heart including localizer sequences took at least 6.5 min, depending on planning complexity. The 3D acquisition was successful in 7 of 26 subjects (27%). Overall image contrast and perceived resolution were lower in the 3D images. Nonetheless, the 3D images had, on average, a moderate cardiac diagnostic quality (median [range]: 3 [1–4]). Standard clinical 2D acquisitions had a high cardiac diagnostic quality (median [range]: 4 [3, 4]). Cardiac measurements were not different between 2D and 3D images (allp > 0.16).ConclusionThe presented free‐breathing whole‐heart fetal 3D radial cine MRI acquisition and reconstruction method enables retrospective visualization of all cardiac views while keeping examination times short. This proof‐of‐concept work produced images with diagnostic quality, while at the same time reducing the planning complexity to a single localizer.
