Two-Dimensional Scattering Center Estimation for Radar Target Recognition Based on Multiple High-Resolution Range Profiles.

A new estimation strategy on locations of two-dimensional target scattering centers for radar target recognition is developed by using multiple high-resolution range profiles (HRRPs). Based on the range information contained in multiple HRRPs obtained from various observation angles, the estimated target scattering centers can be successfully located at the intersection points of the lines passing through the multiple HRRP points. This geometry-based algorithm can significantly reduce the computational complexity while ensuring the ability to estimate the two-dimensional target scattering centers.

Distributions of MICA and MICB Alleles Typed by Amplicon-Based Next-Generation Sequencing in South Koreans.

Major histocompatibility complex class I chain-related genes A and B (MICA and MICB) play a role as ligands in activating the NKG2D receptor expressed in natural killer cells, γδ T-cells and αβ CD8 T-cells and have been defined in human diseases and haematopoietic stem cell transplantation (HSCT). MICA and MICB alleles were genotyped at the three-field level by amplicon-based next-generation sequencing (NGS) using a MiSeqDx system and compared with the results from previous studies in healthy South Korean donors. Exons 2-5 of MICA and exons 2-4 of MICB were amplified using a multiplex polymerase chain reaction (PCR).

Effect of neoadjuvant chemotherapy on effect-site concentration of propofol for sedation in patients with breast cancer.

Background: Some studies have demonstrated that chemotherapy drugs enhance sensitivity to anesthetics owing to its systemic toxicity, while others have demonstrated that chemotherapy drugs have no effect. This study aimed to determine whether neoadjuvant chemotherapy influences the effect-site concentration (Ce) of propofol for sedation in patients withbreast cancer.

Methods: This study included patients aged 19-75 years who were scheduled to undergobreast cancer surgery under general anesthesia.

Extraction and Concentration of Waste Stems with Antioxidants and Anti-Melanogenesis Activity as a Novel Skin Whitening Agent for Natural Cosmetic Prototypes.

The root of (Willd.) is used commercially in different products, including dietary supplements, cosmetics, and teas, but its stem part is rarely used and studied. Therefore, this study evaluated the antioxidant and anti-melanogenesis activities of the bioactive fraction of stem and investigated whether the activated carbon decolorization technique would have an impact on its activity and chemical composition.

Comparison of the performance of phase lag entropy and bispectral index for monitoring the depth of sedation under dexmedetomidine sedation: A prospective, observational, and non-inferiority trial.

Study Objective: Although the performance of phase lag entropy (PLE), a new depth-of-sedation monitor based on the diversity of temporal patterns in the phase relationships in electroencephalogram (EEG) data, during propofol sedation has been proven through several studies, since different sedatives have different effects on EEG, we aimed to evaluate the performance of the PLE in comparison with the bispectral index (BIS) during dexmedetomidine sedation.

Design: A prospective, observational, and non-inferiority trial.

Setting: Tertiary university hospital operating room.

Phenolic Profile and Fingerprint Analysis of Leaves Extract with Endothelial Protective Activity.

In contrast to the stem and fruit of , leaves as a source rich in phenolic compounds with potentially beneficial pharmacological activities have been largely overlooked. To develop and use leaves as a resource, we evaluated its potential as a cardiovascular-protective agent. Herein, we investigated the effects and potential mechanisms of leaves extract on lipopolysaccharide (LPS)-induced inflammatory responses in human umbilical vein endothelial cells.

Kesterite Solar Cells: Insights into Current Strategies and Challenges.

Earth-abundant and environmentally benign kesterite CuZnSn(S,Se) (CZTSSe) is a promising alternative to its cousin chalcopyrite Cu(In,Ga)(S,Se) (CIGS) for photovoltaic applications. However, the power conversion efficiency of CZTSSe solar cells has been stagnant at 12.6% for years, still far lower than that of CIGS (23.

A Unified Deep-Learning Model for Classifying the Cross-Country Skiing Techniques Using Wearable Gyroscope Sensors.

The automatic classification of cross-country (XC) skiing techniques using data from wearable sensors has the potential to provide insights for optimizing the performance of professional skiers. In this paper, we propose a unified deep learning model for classifying eight techniques used in classical and skating styles XC-skiing and optimize this model for the number of gyroscope sensors by analyzing the results for five different configurations of sensors. We collected data of four professional skiers on outdoor flat and natural courses.

Improvement of Pre-Annealed Cu(In, Ga)Se2 Absorbers for High Efficiency.

We used a DC-sputtering method to deposit the precursor (Cu3Ga/In) onto Mo with 1 um thick/soda-lime glass (SLG). We moved it onto a graphite crucible for the pre-annealing process, and the pressure of the process tube was about 10 torr without Ar gas flow. The crucible in quartz tube was heated by halogen lamp to 250 degrees C for 30 min, and then raised to 550 degrees C for 10 min under a selenium atmosphere.

Potential of IMU Sensors in Performance Analysis of Professional Alpine Skiers.

In this paper, we present an analysis to identify a sensor location for an inertial measurement unit (IMU) on the body of a skier and propose the best location to capture turn motions for training. We also validate the manner in which the data from the IMU sensor on the proposed location can characterize ski turns and performance with a series of statistical analyses, including a comparison with data collected from foot pressure sensors. The goal of the study is to logically identify the ideal location on the skier's body to attach the IMU sensor and the best use of the data collected for the skier.
