Device-free indoor localization and tracking using commercial millimeter wave radars have attracted much interest lately due to their non-intrusive nature high spatial resolution. However, it is challenging achieve accuracy rich multipath reflection occlusion in environments. Static objects with non-negligible reflectance of mmWave signals interact moving human subjects generate time-varying ghosts shadow ghosts, which can be easily confused as real subjects. To characterize the complex...

The present study aimed to investigate the potential role of microRNA (miR)-214 in targeting phosphatase and tensin homolog (PTEN)-mediated phosphoinositide 3-kinase (PI3K)/Akt signaling pathway ovarian cancer (OC). target gene miR-214 was determined by luciferase reporter assay indicated be PTEN. Human SK-OV-3 cells were transfected with a inhibitor mimic, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) used detect relative expression miR-214. MTT performed cell...

The ultrasonic-assisted extraction process and antioxidant activity of flavonoids from Sophora flavescens were investigated in this study. In order to optimize the flavescens, influence time, methanol concentration, ultrasonic temperature, solvent-to-material ratio was analyzed. Results showed that yields reached a maximum with time 30 min, concentration 80%, temperature 80 °C, 26 mL/g. determined by HPLC, mean trifolirhizin, formononetin, isoxanthohumol, maackiain, kurarinone under optimal...

Over the past few years, dictionary learning (DL)-based methods have been successfully used in various image reconstruction problems. However, traditional DL-based computed tomography (CT) are patch-based and ignore consistency of pixels overlapped patches. In addition, features learned by these always contain shifted versions same features. recent convolutional sparse coding (CSC) has developed to address this paper, inspired several successful applications CSC field signal processing, we...

To explore the anti-depression effect of Suanzaoren Decoction(SZRD), regulatory effects on endogenous metabolites in liver rats with depression induced by chronic unpredictable mild stress(CUMS) were analyzed using LC-MS metabolomics. The randomly divided into normal control group, model low-dose SZRD high-dose and positive drug group. CUMS was replicated applying a variety stimuli, such as fasting water deprivation, ice swimming, hot day night reversal, tail clamping, restraint for rats....

Device-free hand gesture is one of the most natural ways to interact with everyday objects. However, existing WiFi-based recognition solutions are typically restricted indoor environments due limited outdoor coverage. Furthermore, achieve high sampling rates, they may interfere normal data transmissions. In this paper, we aim develop a robust dynamic interaction system that can be ubiquitously deployed using Long-term Evolution (LTE) mobile terminals. Through both empirical studies and...

Wireless signals have been widely utilized for human sensing. However, wireless sensing systems face a fundamental limitation, i.e., the device must keep static during process. Also, when fine-grained motions such as respiration, target is required to stay stationary. This because relies on signal variations When moving or body moving, variation caused by area (e.g., chest respiration sensing) mixed with induced other parts, failing In this paper, we propose MSense, general solution deal...

Long non-coding (lnc)RNA hypoxia inducible factor 1α-antisense RNA 1 (HIF1A-AS1) not only participates in different types of malignancies, but also serves pivotal roles thoracic aortic aneurysms, which suggests its possible involvement intracranial aneurysms. Therefore, the present study aimed to investigate Expression levels HIF1A-AS1 and transforming growth (TGF)-β1 blood patients with aneurysms healthy controls were detected using reverse transcription-quantitative polymerase chain...

Floor plan construction has been one of the key techniques in many important applications such as indoor navigation, location-based services, and emergency rescue. Existing floor methods require expensive dedicated hardware (e.g., Lidar or depth camera), may not work low-visibility environments smoke, fog dust). In this paper, we develop a low-cost Ultra Wideband (UWB)-based system (named UWBMap) that is mounted on mobile robot platform to construct through smoke. UWBMap leverages...

Dried roots of Polygala tenuifolia (YuanZhi in Chinese) are widely used Chinese herbal medicine. These components YuanZhi have significant anti-oxidation properties owing to high levels 3,6'-disinapoylsucrose (DISS) and Polygalaxanthone III (PolyIII). In order efficiently extract natural medicines, response surface methodology (RSM) least squares support vector machine (LSSVM) were for the modeling optimization ultrasound-assisted extraction DISS PolyIII together determine antioxidant...

To investigate the effect of kangaroo mother care on psychological stress response and sleep quality mothers with premature infants admitted to neonatal intensive unit (NICU).A randomized controlled design was used recruit participants. The study recruited 126 in NICU from January 2019 2020. participants were divided into experimental control groups according random number table method (63 per group). group managed conventional infant treatment, nursing programme, discharge education,...

Over 60 years ago Waddington proposed an epigenetic landscape model of cellular differentiation, whereby cell-fate transitions are modelled as canalization events, with stable cell states occupying the basins or attractor 1, 2 . A key ingredient this is energy potential, height 3 , which correlates cell-potency. To date, very few explicit biophysical models for estimating single-cell potency have been proposed. Using 9 independent experiments, encompassing over 6,600 high-quality RNA-Seq...

Background: Long non-coding RNAs (lncRNAs) are key regulators of pancreatic cancer development and involved in ferroptosis regulation. LncRNA transcript levels serve as a prognostic factor for cancer. Therefore, identifying ferroptosis-related lncRNAs (FRLs) with value is critical. Methods: In this study, FRLs were identified by combining The Cancer Genome Atlas (TCGA) FerrDb databases. For training cohort, univariate Cox, Lasso, multivariate Cox regression analyses applied to identify...

Murine IL-4 is a pleiotropic cytokine with undefined core functional region for eliciting downstream signaling. We used molecular modeling to predict the binding sites recognized by an anti-IL-4-neutralizing mAb (11B.11) and peptide phage display delineate their makeup. The results of these approaches were confirmed site-directed mutagenesis analysis. suggest that amino acid residues spanning from 79 86 (QRLFRAFR) on are major site 11B.11. Furthermore, experiments demonstrate R80, R83 R86,...

Stroke is the leading cause of death in elderly. Traditional Chinese medicine provides an exciting strategy for treating stroke. Previous reports indicated that Longshengzhi capsules (LSZ), a modified formula, reduced formed thrombi and oxidative stress were promising clinical treatment ischemic However, specific therapeutic effect mechanism LSZ are still ambiguous. This study aimed to define effects on proinflammatory mediators neuroprotective middle cerebral artery occlusion refusion...
