Pretreatment of biomass with phosphoric acid (HPO) for biochar production was expected to improve carbon (C) retention, porosity structure, and the sorption ability biochar. This study investigated interaction phosphorus C structure elucidate mechanisms by which HPO simultaneously captured created micropores. Sawdust soaked in diluted dried pyrolytic generation at 350, 500, 650°C. Results showed that pretreatment resulted 70 80% retention biochar, compared only about 50% remaining without...

Maternal–fetal immune tolerance guarantees a successful pregnancy throughout gestation. HLA-G, nonclassical human leukocyte antigen (HLA) molecule exclusively expressed in extravillous trophoblasts (EVT), is crucial factor establishing maternal–fetal by interacting with inhibitory receptors on various maternal cells residing the uterus. While trophoblast-specific cis-regulatory elements impacting HLA-G transcription have been described, identity of trans-acting factors controlling expression...

The distinct human leukocyte antigen (HLA) class I expression pattern of extravillous trophoblasts (EVT) endows them with unique tolerogenic properties that enable successful pregnancy. Nevertheless, how this process is elaborately regulated remains elusive. Previously, E74 like ETS transcription factor 3 (ELF3) was identified to govern high-level HLA-C in EVT. In the present study, ELF3 found bind enhancer region two adjacent NOD-like receptor (NLR) genes, NLR family pyrin domain-containing...

In this study, using pressurized air to split the soil between a booster tube and plastic vertical drain (PVD), an is employed reduce clogging such that vacuum preloading of dredged promoted. Under framework Hansbo's theory, analysis method conducted understand consolidation improved by assisted booster. Both increases in stress permeability are introduced consider effect on soil. The calculated results compared with existing cases verify proposed method. A feasible range increments for...

Nowadays, smart contracts manage more and digital assets have become an attractive target for adversaries. To prevent from malicious attacks, a thorough test is indispensable must be finished before deployment because cannot modified after being deployed. Fuzzing important testing approach, but most existing contract fuzzers can hardly solve the constraints which involve deeply nested conditional statements, resulting in low coverage. address this problem, we propose Targy, efficient...

The power system stabilizer(PSS) generates additional excitation signals to suppress the negative damping of system, and low-frequency oscillation system. simulation model transient stability is established, input exit PSS are compared analyzed. PSC-9410A digital regulator a plant in Heilongjiang Province analyzed verified. results show can effectively maintain stability. research provide theoretical basis for optimization control

Abstract Background and Aims Hepatocellular Carcinoma (HCC) is often diagnosed late, limiting curative treatment options. Conversely, early detection in cirrhotic patients through screening offers high cure rates but underutilized misses cases occurring individuals without cirrhosis. We aimed to build, validate, simulate the deployment of models for HCC risk stratification using routinely collected Electronic Health Record (EHR) data from a geographically racially diverse U.S. population....

Abstract The lack of an MMC reliability evaluation approach that incorporates data on essential components' health monitoring in the already related research prevents from being further improved. Therefore, this article proposes a real‐time method multi‐state IGBT module through iterative calculation Markov chain model. degradation process is divided into multiple states based monitored bond wire failure, and failure rate updated real time using accumulated junction temperature. proposed can...

Low cardiac output syndrome (LCOS) is the most serious physiological abnormality with high mortality for patients after surgery. This study aimed to explore multidimensional data of clinical features and outcomes provide individualized care LCOS. The electronic medical information intensive units (ICUs) was extracted from a tertiary hospital in South China. We included who were diagnosed LCOS ICU database. used consensus clustering approach based on patient characteristics, laboratory data,...

Mobile edge computing (MEC) has been regarded as a promising technique to support latencysensitivity and computation-intensive serves. However, the low offloading rate caused by random channel fading characteristic becomes major bottleneck in restricting performance of MEC. Fortunately, reconfigurable intelligent surface (RIS) can alleviate this problem since it boost both spectrum- energy- efficiency. Different from existing works adopting either fully active or passive RIS, we propose...

Abstract The Microgrid (MG) is a flexible system composed of paralleled inverters. When the MG runs in grid-connected mode, first step to synchronize with grid stably. However, weak may interact synchronization loops and result instability issues, where steady-state coming from loss equilibrium points remains be studied. Concretely, loop each inverter determines point. While, when inverters work together, interactions among complicate analysis. To recognize mechanism stability MG, kind...

In order to alleviate the pressure of terminal devices deal with big-data and low-delay services, a resource allocation algorithm is studied for mobile edge computing networks full-duplex relays. Firstly, constraints maximum task latency, ability users, transmit power users relays are considered achieving total energy consumption minimization by jointly optimizing relay selection subcarrier factor, user offloading coefficient, transmission Secondly, based on alternating iteration method...

ABSTRACT Background: Emerging evidence has demonstrated that pyroptosis plays a vital role in the development of sepsis. However, few studies have examined this field systemically.

Then, VOSviewer CiteSpace used for further analysis. Results: The showed an...

As the Internet of Things (IoT) advances by leaps and bounds, a multitude devices are becoming interconnected, marking onset an era where all things connected. While this growth opens up opportunities for novel products applications, it also leads to increased energy demand battery reliance IoT devices, creating significant bottleneck that hinders sustainable progress. At juncture, backscatter communication (BackCom), as low-power passive method, emerges one promising solutions impasse...

Abstract The change of operation mode the HVDC project causes a external characteristic converter valve, and reverse recovery thyristor inside valve changes accordingly. Therefore, charge measurement values thyristors under different operating conditions cannot be directly compared, status evaluated online. method measuring series based on turn-off voltage is presented in this paper. Then, analyzed, characteristics modes are discussed. Secondly, factors that affect analyzed essentially,...
