The mystic role of high-entropy designs in rechargeable metal-ion batteries:A review

Rechargeable metal-ion batteries, such as lithium-ion batteries(LIBs) and sodium-ion batteries(SIBs),have raised more attention because of the large demand for energy storage solutions. Undoubtedly, electrode materials and electrolytes are key parts of batteries, exhibiting critical influence on the reversible capacity and span life of the metal-ion battery. Nonetheless, researchers commonly express concerns regarding the stability of both electrodes and electrolytes. Given its commendable stability attributes,high-entropy materials have garnered widespread acclaim and have been applied in many fields since their inception, notably in energy storage. However, while certain high-entropy designs have achieved substantial breakthroughs, some have failed to meet anticipated outcomes within the high energy density energy storage materials. Moreover, there is a lack of comprehensive summary research on the corresponding mechanisms and design principles of high-entropy designs. This review examines the current high-entropy designs for cathodes, anodes, and electrolytes, aiming to summarize the design principle,potential mechanisms, and electrochemical performance. We focus on their structural characteristics,interface characteristics, and prospective development trends. At last, we provide a fair evaluation along-side succinct development suggestions.

In-beam gamma rays of CSNS Back-n characterized by black resonance filter

The back-streaming white-neutron beamline(Back-n)of the China Spallation Neutron Source is an essential neutronresearch platform built for the study of nuclear data,neutron physics,and neutron applications.Many types of cross-sectional neutron-reaction measurements have been performed at Back-n since early 2018.These measurements have shown that a significant number of gamma rays can be transmitted to the experimental stations of Back-n along with the neutron beam.These gamma rays,commonly referred to as in-beam gamma rays,can induce a non-negligible experimental background in neutron-reaction measurements.Studying the characteristics of in-beam gamma rays is important for understanding the experimental background.However,measuring in-beam gamma rays is challenging because most gamma-ray detectors are sensitive to neutrons;thus,discriminating between neutron-induced signals and those from in-beam gamma rays is difficult.In this study,we propose the use of the black resonance filter method and a CeBr_(3) scintillation detector to measure the characteristics of the in-beam gamma rays of Back-n.Four types of black resonance filters,^(181)Ta,^(59)Co,^(nat)Ag,and^(nat)Cd,were used in this measurement.The time-of-flight(TOF)technique was used to select the detector signals remaining in the absorption region of the TOF spectra,which were mainly induced by in-beam gamma rays.The energy distribution and flux of the in-beam gamma rays of Back-n were determined by analyzing the deposited energy spectra of the CeBr_(3) scintillation detector and using Monte Carlo simulations.Based on the results of this study,the background contributions from in-beam gamma rays in neutron-reaction measurements at Back-n can be reasonably evaluated,which is beneficial for enhancing both the experimental methodology and data analysis.

Plant aquaporins:Their roles beyond water transport

Compared to other organisms,plants have evolved a greater number of aquaporins with diverse substrates and functions to adapt to ever-changing environmental and internal stimuli for growth and development.Although aquaporins were initially identified as channels that allow water molecules to cross biological membranes,progress has been made in identifying various novel permeable substrates.Many studies have characterized the versatile physiological and biophysical functions of plant aquaporins.Here,we review the recent reports that highlight aquaporin-facilitated regulation of major physiological processes and stress tolerance throughout plant life cycles as well as the potential prospects and possibilities of applying aquaporins to improve agricultural productivity,food quality,environmental protection,and ecological conservation.

Diagnostic value of digital continuous bowel sounds in critically ill patients with acute gastrointestinal injury: A prospective observational study

BACKGROUND Acute gastrointestinal injury(AGI)is common in intensive care unit(ICU)and worsens the prognosis of critically ill patients.The four-point grading system proposed by the European Society of Intensive Care Medicine is subjective and lacks specificity.Therefore,a more objective method is required to evaluate and determine the grade of gastrointestinal dysfunction in this patient population.Digital continuous monitoring of bowel sounds and some biomarkers can change in gastrointestinal injuries.We aimed to develop a model of AGI using continuous monitoring of bowel sounds and biomarkers.AIM To develop a model to discriminate AGI by monitoring bowel sounds and biomarker indicators.METHODS We conducted a prospective observational study with 75 patients in an ICU of a tertiary-care hospital to create a diagnostic model for AGI.We recorded their bowel sounds,assessed AGI grading,collected clinical data,and measured biomarkers.We evaluated the model using misjudgment probability and leave-one-out cross-validation.RESULTS Mean bowel sound rate and citrulline level are independent risk factors for AGI.Gastrin was identified as a risk factor for the severity of AGI.Other factors that correlated with AGI include mean bowel sound rate,amplitude,interval time,Sequential Organ Failure Assessment score,Acute Physiology and Chronic Health Evaluation II score,platelet count,total protein level,blood gas potential of hydrogen(pH),and bicarbonate(HCO3-)level.Two discriminant models were constructed with a misclassification probability of<0.1.Leave-one-out cross-validation correctly classified 69.8%of the cases.CONCLUSION Our AGI diagnostic model represents a potentially effective approach for clinical AGI grading and holds promise as an objective diagnostic standard for AGI.

Global research landscape of Peutz-Jeghers syndrome and successful endoscopic management of intestinal intussusception in patients with recurrent laparotomies

Complementary monogamy and polygamy properties among multipartite systems

Monogamy and polygamy relations are essential properties of quantum entanglement,which characterize the distributions of entanglement in multipartite systems.In this paper,we establish the general monogamy relations forγ-th(0≤γ≤α,α≥1)power of quantum entanglement based on unified-(q,s)entanglement and polygamy relations forδ-th(δ≥β,0≤β≤1)power of entanglement of assistance based on unified-(q,s)entanglement of assistance,which provides a complement to the previous research in terms of different parameter regions ofγandδ.These results are then applied to specific quantum correlations,e.g.,entanglement of formation,Renyi-q entanglement of assistance and Tsallis-q entanglement of assistance to get the corresponding monogamy and polygamy inequalities.Moreover,typical examples are presented for illustration.

Identification and characterization of microRNAs in raw milk during different periods of lactation, commercial fluid, and powdered milk products

Recent baby formula milk powder contamination incidents have shown that the classic markers or standards in milk quality control are insufficient in identifying ＂manipulated＂ poor-quality milk. In the present study, we demonstrated for the first time that cow milk contains large amounts of microRNAs （miRNAs） and that the unique expression profile of milk-specific miRNAs can serve as a novel indicator and possible new standard for the quafity control of raw milk and milk-related commercial products, such as fluid milk and powdered formula milk. First, using Solexa sequencing, we systematically screened miRNA expression in raw milk and identified a total of 245 miR- NAs in raw milk. Unlike other classic biomarkers whose expression levels are nearly identical at different periods of lactation, individual miRNAs can be significantly altered during lactation process, implicating that miRNAs may be a more accurate indicator to reflect the quality alteration of milk. Second, using TaqMan probe-based miRNA quantitative RT-PCR, we further identified seven miRNAs that have a relatively consistent expression throughout the lactation process, and more importantly, the expression profile of these seven milk-specific miRNAs can serve as an ideal biomarker for discriminating poor-quality or ＂manipulated＂ milk from pure raw milk, as well as for the quality control of commercial milk products, such as fluid milk and powdered formula milk. Together, our findings provide a basis for understanding the physiological role of milk miRNAs and a new potential standard for determining the quality of raw milk or milk-related commercial products.

Differential analysis of lymph node metastasis in histological mixed-type early gastric carcinoma in the mucosa and submucosa

AIM To investigate the relationship between histological mixed-type of early gastric cancer(EGC) in the mucosa and submucosa and lymph node metastasis(LNM).METHODS This study included 298 patients who underwent gastrectomy for EGC between 2005 and 2012. Enrolled lesions were divided into groups of pure differentiated(pure D), pure undifferentiated(pure U), and mixed-type according to the proportion of the differentiated and undifferentiated components observed under a microscope. We reviewed the clinicopathological features, including age, sex, location, size, gross type, lymphovascular invasion, ulceration, and LNM, among the three groups. furthermore, we evaluated the predictors of LNM in the mucosa-confined EGC.RESULTS Of the 298 patients, 165(55.4%) had mucosa-confined EGC and 133(44.6%) had submucosa-invasive EGC. Only 13(7.9%) cases of mucosa-confined EGC and 30(22.6%) cases of submucosa-invasive EGC were observed to have LNM. The submucosal invasion(OR = 4.58, 95%CI: 1.23-16.97, P = 0.023), pure U type(OR = 4.97, 95%CI: 1.21-20.39, P = 0.026), and mixedtype(OR = 5.84, 95%CI: 1.05-32.61, P = 0.044) were independent risk factors for LNM in EGC. The rate of LNM in mucosa-confined EGC was higher in the mixedtype group(P = 0.012) and pure U group(P = 0.010) than in the pure D group, but no significant difference was found between the mixed-type group and pure U group(P = 0.739). Similarly, the rate of LNM in the submucosa-invasive EGC was higher in the mixedtype(P = 0.012) and pure U group(P = 0.009) than in the pure D group but was not significantly different between the mixed-type and pure U group(P = 0.375). Multivariate logistic analysis showed that only female sex(OR = 5.83, 95%CI: 1.64-20.70, P = 0.028) and presence of lymphovascular invasion(OR = 13.18, 95%CI: 1.39-125.30, P = 0.020) were independent risk factors for LNM in mucosa-confined EGC, while histological type was not an independent risk factor for LNM in mucosa-confined EGC(P = 0.106).CONCLUSION for mucosal EGC, histological mixed-type is not an independent risk factor for LNM and could be managed in the same way as the undifferentiated type.

Expression of high mobility group protein B1 in the lungs of rats with sepsis

BACKGROUND： Vibrio vulnifi cus inside the body could activate the NF-!B signaling pathwayand initiate the inflammatory cascade. The lung is one of the earliest organs affected by sepsisassociated with acute lung injury. High mobility group protein B1 （HMGB1） is an important late-actingpro-infl ammatory cytokine involving in the pathophysiology of sepsis. It is also involved in the injuryprocess in the lung, liver and intestine. There has been no report on the involvement of HMGB1 inVibrio vulnifi cus sepsis-induced lung injury.METHODS： Sixty rats were randomly divided into a normal control group （group A, n=10） anda Vibrio vulnificus sepsis group （group B, n=50）. Sepsis was induced in the rats by subcutaneousinjection of Vibrio vulnificus （concentration 6×108 cfu/mL, volume 0.1 mL/100g）） into the left lowerlimbs. The rats in group B were sacrifi ced separately 1, 6, 12, 24, and 48 hours after the infection.Their lungs were stored as specimens, lung water content was measured, and lung pathology wasobserved under a light microscope. The expressions of the HMGB1 gene and protein in the lungswere detected by RT-PCR and Western blot. Data were analyzed with one-way analysis of variance（ANOVA） and the LSD method for pair-wise comparison between the two groups. P〈0.05 wasconsidered statistically signifi cant.RESULTS： Compared to group A （0.652±0.177）, HMGB1 mRNA expression in the lungs ofgroup B was signifi cantly higher at 0 hour （1.161±0.358, P=0.013）, 24 hours （1.679±0.235, P=0.000）,and 48 hours （1.258±0.274, P=0.004） （P〈0.05）, and peaked at 24 hours. Compared to group A（0.594±0.190）, HMGB1 protein expression at 6 hours （1.408±0.567, P=0.026） after infection wassignificantly increased （P〈0. 05）, and peaked at 24 hours （2.415±1.064, P=0.000） after infection.Compared to group A （0.699±0.054）, lung water content was significantly increased at 6 hours（0.759±0.030, P=0.001）,12 hours （0.767±0.023, P=0.000）, 24 hours （0.771±0.043, P=0.000） and 48hours （0.789±0.137, P=0.000） after infection （P〈0.05）. Compared to group A, pathological changesat 12 hours in group B indicate marked pulmonary vascular congestion, interstitial edema andinfl ammatory infi ltration. Alveolar cavity collapse and boundaries of the alveolar septum could not beclearly identifi ed.CONCLUSION： Vibrio vulnifi cus sepsis can lead to injury in rat lungs, and increased HMGB1expression in lung tissue may be one of the mechanisms for injury from Vibrio vulnifi cus sepsis.
