PurposeTo investigate the effects of using different parallel‐transmit (pTx) head coils and specific absorption rate (SAR) supervision strategies on pTx pulse design for ultrahigh‐field MRI using a 3D‐MPRAGE sequence.MethodsThe PTx universal pulses (UPs) and fast online‐customized (FOCUS) pulses were designed with pre‐acquired data sets (B0, B1+ maps, specific absorption rate [SAR] supervision data) from two different 8 transmit/32 receive head coils on two 7T whole‐body MR systems. For one coil, the SAR supervision model consisted of per‐channel RF power limits. In the other coil, SAR estimations were done with both per‐channel RF power limits as well as virtual observation points (VOPs) derived from electromagnetic field (EMF) simulations using three virtual human body models at three different positions. All pulses were made for nonselective excitation and inversion and evaluated on 132 B0, B1+, and SAR supervision datasets obtained with one coil and 12 from the other. At both sites, 3 subjects were examined using MPRAGE sequences that used UP/FOCUS pulses generated for both coils.ResultsFor some subjects, the UPs underperformed when simulated on a different coil from which they were derived, whereas FOCUS pulses still showed acceptable performance in that case. FOCUS inversion pulses outperformed adiabatic pulses when scaled to the same local SAR level. For the self‐built coil, the use of VOPs showed reliable overestimation compared with the ground‐truth EMF simulations, predicting about 52% lower local SAR for inversion pulses compared with per‐channel power limits.ConclusionFOCUS inversion pulses offer a low‐SAR alternative to adiabatic pulses and benefit from using EMF‐based VOPs for SAR estimation.
Two‐region flow caused by pumping at a partial penetration well in a leaky confined aquifer
Authors: Feng Qinggao , Zhan Hongbin 
Published: January 2023

AbstractAn analytical model for depicting two‐region flow caused by constant‐rate pumping at a partially penetrating well in a leaky confined aquifer is established. The two‐region flow is described by the radial Izbash non‐Darcy flow in the vicinity of the abstraction well and Darcy flow away from the abstraction well in the pumped aquifer. The model considers the effects of aquitard storage, wellbore storage, and wellbore skin. The semi‐analytical solutions of drawdown are developed by means of a linearization procedure combined with Laplace transform and separation of variables. The time‐domain drawdowns are then obtained by using the Stehfest method for numerical Laplace inversion. The solutions encompass previous solutions for one or two‐region flow to a partially penetrating well in a (non‐)leaky confined aquifer. The drawdown response in the abstraction well, non‐Darcy region, and Darcy region is investigated, and sensitivity analysis is made to assess the impact of various controlling parameters. The results demonstrate that the intermediate and late‐stage drawdowns in the abstraction well and non‐Darcy region for the two‐region flow model are larger than the corresponding values for the non‐Darcy flow model. The drawdown in the Darcy region for the two‐region flow model is larger than that for the Darcy flow model throughout the pumping duration. The results of sensitivity analysis show that the drawdowns in the abstraction well, non‐Darcy region, and Darcy region are most sensitive to the non‐Darcy constant n, and is very sensitive to the well configuration, and horizontal hydraulic conductivity of the Darcy region.

AbstractAimsTo examine patients' perceptions of care quality following a same‐day procedure in the cardiac catheterization laboratory and understand the extent to which they were prepared for discharge.DesignSingle‐centre, mixed‐methods study.MethodsPostdischarge, online survey of patients who underwent a same‐day procedure in the cardiac catheterization laboratory (n = 150) and one‐on‐one interviews with 13 of these patients.ResultsSurvey responses were positive with mean scores between 4.39–4.83 out of five and 63.3% of respondents (n = 95) extremely likely to recommend the service to others. Interview data analysis identified three themes: the care experience, information and education for safe discharge, and follow‐up needs. Participants spoke highly of their interactions with clinicians and were satisfied with their care experience. Mode and content of information delivered varied, with some participants lacking guidance about postdischarge health management and clarity about follow‐up plans.Patient or public contributionParticipants were patients.

AbstractObjectiveThis study aimed to examine whether baseline gray matter (GM) volume and structural covariance patterns could predict body fat gain over 1 to 2 years in a relatively large sample.MethodsVoxel‐based morphometry (VBM) analysis was applied to examine the association between baseline GM volume and body fat gain in 502 participants over 1 to 2 years. Furthermore, this study tested whether the structural covariances between the regions identified as seeds from VBM analysis and the rest of the brain were associated with future body fat gain.ResultsA significant positive association was observed between baseline GM volume in the perigenual anterior cingulate cortex (pgACC) and body fat gain over 1 to 2 years. Furthermore, relative to those with lower future body fat gain, pgACC covaried more extensively with the middle frontal gyrus, middle temporal gyrus, inferior temporal gyrus, and cerebellum in participants with higher future body fat gain.ConclusionsUsing VBM and structural covariance network analysis, the current study revealed that higher GM volume of pgACC and its increased structural covariances with specific brain regions were associated with future weight gain, which may guide the development of more effective prevention and treatment interventions for obesity.

AbstractObjectivesTo evaluate the performance of cell‐free DNA (cfDNA) screening for common fetal aneuploidies, choice of prenatal procedure, and chromosome conditions identified during pregnancy after low‐risk cfDNA screening.MethodA single‐center prenatal cfDNA screening test was employed to detect trisomies 21, 18, and 13 (T21, T18, T13) and sex chromosome aneuploidies (SCAs). Test performance, choice of prenatal procedure, and cytogenetic results in pregnancies with low‐risk cfDNA screening were reviewed.ResultsCfDNA screening of 38,289 consecutive samples identified 720 (1.9%) pregnancies at increased risk for aneuploidy. Positive predictive values (PPVs) for high‐risk singleton pregnancies were 98.5% (T21), 92.5% (T18) and 55.2% (T13). PPVs for SCAs ranged from 30.6% to 95.2%. Most women elected chorionic villus sampling for prenatal diagnosis of T21, T18 and T13; amniocentesis and/or postnatal testing were commonly chosen for SCAs. Cytogenetic tests from 616 screen‐negative pregnancies identified 64 cases (12.7%) with chromosome conditions not detected by cfDNA screening, including triploidy (n = 30) and pathogenic and likely pathogenic copy number variants (n = 34). A further 15 (0.04%) false‐negative common aneuploidy results were identified.ConclusionsCfDNA screening was highly accurate for detecting fetal aneuploidy in this general‐risk obstetric population. Fetal ultrasound and prenatal diagnostic testing were important in identifying chromosome conditions in pregnancies screened as low‐risk.

AbstractThe sugar industry is one of the most wastewater‐producing industries and it contains high content of organic and inorganic substances. Treating and reusing wastewater has significant importance because sugar industry needs to use a high volume of water. In this study, sugar industry wastewater was treated under subcritical conditions and the impacts of reaction temperature and duration over TOC removal percentage were investigated. Additionally, the impact of NaOH concentration over TOC removal percentage was examined. The highest TOC removal was obtained almost 95 % in the presence of 0.1 M of NaOH at 240 °C for 90 min of reaction duration. Treatment of sugar industry wastewater by subcritical water oxidation followed the second‐order reaction kinetic model and the activation energy was found as 11.41 kJ/mol. Furthermore, the intermediate products were identified via GC‐MS.

AbstractAchieving fast transmembrane transmission of molecules in organisms is a challenging problem. Inspired by the transport of Dopmine (DA) in organisms, the DA transporter (DAT) binds to DA in a way that has a ring recognition (the recognition group is the tryptophan group). Herein, D‐Tryptophan‐pillar[5]arene (D‐Trp‐P5) functionalized conical nanochannel is constructed to achieve fast transmission of DA. The D‐Trp‐P5 functionalized nanochannel enables specific wettability recognition of DA molecules and has great cycle stability. With the controlling of voltage to wettability, the transport flux of DA is up to 499.73 nmol cm−2 h−1 at −6 V, 16.88 times higher than that under positive voltages. In response to these results, a high‐throughput DA transport device based on controlled electricity‐wettability is provided.

AbstractPrecise detection involving droplets based on functional surfaces is promising for the parallelization and miniaturization of platforms and is significant in epidemic investigation, analyte recognition, environmental simulation, combinatorial chemistry, etc. However, a challenging and considerable task is obtaining mutually independent droplet arrays without cross‐contamination and simultaneously avoiding droplet evaporation‐caused quick reagent loss, inaccuracy, and failure. Herein, a strategy to generate mutually independent and hardly‐volatile capsular droplet arrays using innovative mosaic patterned surfaces is developed. The evaporation suppression of the capsular droplet arrays is 1712 times higher than the naked droplet. The high evaporation suppression of the capsular droplet arrays on the surfaces is attributed to synergistic blocking of the upper oil and bottom mosaic gasproof layer. The scale‐up of the capsular droplet arrays, the flexibility in shape, size, component (including aqueous, colloidal, acid, and alkali solutions), liquid volume, and the high‐precision hazardous substance testing proves the concept's high compatibility and practicability. The mutually independent capsular droplet arrays with amazingly high evaporation suppression are essential for the new generation of high‐performance open‐surface microfluidic chips used in COVID‐19 diagnosis and investigation, primary screening, in vitro enzyme reactions, environmental monitoring, nanomaterial synthesis, etc.

AbstractElectrolyte additive is an effective strategy to inhibit the uncontrolled growth of Li dendrites for lithium metal batteries (LMBs). However, most of the additives are complex synthesis and prone to decompose in cycling. Herein, in order to guide the homogeneous deposition of Li+, carbonized polymer dots (CPDs) as electrolyte additives are successfully designed and synthesized by microwave (M‐CPDs) and hydrothermal (H‐CPDs) approaches. The controllable functional groups containing N or O (especially pyridinic‐N, pyrrolic‐N, and carboxyl group) enable CPDs to keep stable in electrolytes for at least 3 months. Meanwhile, the clusters formed between CPDs and Li+ through electrostatic interaction effectively guide the uniform Li dispersion and limit the “tip effect” and dendrite formation. Moreover, as lithiophilic groups increase, the strong electrostatic interference for the solvation effect of Li+ in the electrolyte is formed, which induces faster Li+ diffusion/transfer. As expected, H‐CPDs achieve the ultra‐even Li+ transfer. The corresponding Li//LiFePO4 full cell delivers a high capacity retention rate of 93.8% after 200 cycles, which is much higher than that of the cells without additives (61.2%) and with M‐CPDs (83.7%) as additives. The strategy in this work provides a theoretical direction for CPDs as electrolyte additives used in energy storage devices.

Published: January 2023

AbstractThis study mainly focuses on revealing the role of PLAGL2 in lung cancer stemness. In vitro and in vivo experiments were performed to evaluate the effects of PLAGL2 on lung cancer cell stemness. Mechanistic analysis using luciferase reporter and ChIP assays were implemented to reveal the underlying mechanisms. The transcriptional factor E2F1 transcriptionally activated PLAGL2 expression via directly binding to PLAGL2 promoter in lung cancer cells. Moreover, PLAGL2 promoted the stemness of lung cancer cells dependent on E2F1‐mediated transcriptional activation. This study provides a potential target for lung cancer progression.

AbstractBackgroundCorncob is a cheap source for biochar in developing countries. No studies reported on use of biochar as sheep fattening supplement.ObjectivesThe goal of this study is to determine the effect of corncob biochar supplementation on growth performance and carcass characteristics of sheep.MethodsTwenty‐four Horro yearling rams (18.6 ± 0.938 kg live weight) were randomly distributed to four groups, control (300 g/day concentrate + local hay ad libitum), BC1.5 (control +1.5 g/day biochar), BC3 (control +3 g/day biochar) and BC4.5 (control +4.5/day biochar). The experimental concentrate consisted of 200 g/day wheat bran and 100 g/day Noug cake. The study consisted of a growth trial of 111 days followed by a digestibility trial of 10 days. Carcass characteristics for all rams were recorded at the end of the trial.ResultsDry matter intake, crude protein intake, dry matter digestibility and acid detergent fibre digestibility of BC1.5 were significantly higher than the control. Corncob biochar supplementation significantly improved daily weight gain and feed conversion ratio of the rams. Supplementation sheep with corncob biochar improved significantly dressing percentage, hindquarters weight, forequarters weight, ribs weight, brisket weigh and rib eye muscle area. There was a significant effect of the dietary treatment on weight of internal organs; however, they were all within the normal range of sheep.ConclusionsCorncob biochar supplementation would be recommended at a level of 1.5 g/day to improve growth performance and carcass characteristics of sheep.

AbstractMany challenges remain before we can fully understand the multifaceted role that natural organic matter (NOM) plays in soil and aquatic systems. These challenges remain despite the considerable progress that has been made in understanding NOM’s properties and reactivity using the latest analytical techniques. For nearly 4 decades, the International Humic Substances Society (IHSS, which is a non-profit scientific society) has distributed standard substances that adhere to strict isolation protocols and reference materials that are collected in bulk and originate from clearly defined sites. These NOM standard and reference samples offer relatively uniform materials for designing experiments and developing new analytical methods. The protocols for isolating NOM, and humic and fulvic acid fractions of NOM utilize well-established preparative scale column chromatography and reverse osmosis methods. These standard and reference NOM samples are used by the international scientific community to study NOM across a range of disciplines from engineered to natural systems, thereby seeding the transfer of knowledge across research fields. Recently, powerful new analytical techniques used to characterize NOM have revealed complexities in its composition that transcend the “microbial” vs. “terrestrial” precursor paradigm. To continue to advance NOM research in the Anthropocene epoch, a workshop was convened to identify potential new sites for NOM samples that would encompass a range of sources and precursor materials and would be relevant for studying NOM’s role in mediating environmental and biogeochemical processes. We anticipate that expanding the portfolio of IHSS reference and standard NOM samples available to the research community will enable this diverse group of scientists and engineers to better understand the role that NOM plays globally under the influence of anthropogenic mediated changes.
Double-edged sword: persistent effects of Communist regime affiliations on well-being and preferences
Authors: Otrachshenko Vladimir , Nikolova Milena , Popova Olga 
Published: January 2023

AbstractDuring Communism, party members and their relatives were typically privileged elites in Central and Eastern Europe (CEE) and the former Soviet Union (FSU). At the same time, secret police informants were often coerced to spy and report on their fellow citizens. After the fall of Communism, CEE countries and the Baltics underwent decommunization, unlike most FSU countries. This paper is the first to empirically distinguish between these two Communist party regime affiliations and study their long-term implications for the well-being and preferences of affiliated individuals and their relatives. In the FSU, we find that individuals connected to the former Communist party are more satisfied with their lives, but those linked to secret police informants seem to have lower life satisfaction than those without such ties. The life satisfaction benefit of having former Communist regime party connections in the FSU is, on average, equivalent to one month’s household income. Simultaneously, the psychological costs of being an informant can amount to two monthly household incomes. In CEE countries, having informant connections is not associated with life satisfaction, but having links to the former Communist party is negatively correlated with subjective well-being. Formal and informal decommunization efforts are an important mechanism behind our findings. We also show that those connected to the former regimes differ from those without such connections in their preferences for democracy and market economy, levels of optimism, and risk tolerance, which provides suggestive evidence for the mechanisms underpinning our findings. Our results underscore that the former Communist regimes produced winners and losers based on the trustee status of their collaborators that decommunization efforts further shaped and solidified. Future decommunization efforts in the FSU may thus have important welfare implications.
