Sparse reservoir computing with vertically coupled vortex spin-torque oscillators for time series prediction.

Spin torque nano-oscillators possessing fast nonlinear dynamics and short-term memory functions are potentially able to achieve energy-efficient neuromorphic computing. In this study, we introduce an activation-state controllable spin neuron unit composed of vertically coupled vortex spin torque oscillators and a-source circuit is proposed and used to build an energy-efficient sparse reservoir computing (RC) system to solve nonlinear dynamic system prediction task. Based on micromagnetic and electronic circuit simulation, the Mackey-Glass chaotic time series and the real motor vibration signal series can be predicted by the RC system with merely 20 and 100 spin neuron units, respectively.

Treatment Strategy Research on a Squirrel-Cage Induction Motor with Broken Rotor Bar Faults.

Squirrel-cage induction motors are increasingly displaying a broken rotor bar fault, which represents both a technical problem and an economic problem. After confirming that the broken rotor bars do not affect the normal start-up and basic working performance of the squirrel-cage induction motor, this paper focuses on the loss and efficiency changes of the motor brought about by the broken rotor bar fault. Using finite element simulation and experimentation, various losses like stator copper loss, iron loss, rotor copper loss, mechanical loss and additional losses, total loss and efficiency are obtained.

Risk factors for myocardial injury at admission of 325 patients with coronavirus disease 2019 in Shanghai, China.

Objective: Myocardial injury leads to higher mortality in COVID-19, but the causes and risk factors are variable. We evaluated the potential risk factors for myocardial injury in COVID-19 patients to improve treatment strategies and reduce mortality.

Methods: This retrospective analysis enrolled 325 COVID-19 patients in Shanghai, China.

Thymosin Alpha-1 Has no Beneficial Effect on Restoring CD4+ and CD8+ T Lymphocyte Counts in COVID-19 Patients.

Dysregulation of immune response was observed in COVID-19 patients. Thymosin alpha 1 (Tα1) is used in the management of COVID-19, because it is known to restore the homeostasis of the immune system during infections and cancers. We aim to observe the longitudinal changes in T lymphocyte subsets and to evaluate the efficacy of Tα1 for COVID-19.

Epidemiology and clinical course of COVID-19 in Shanghai, China.

Novel coronavirus pneumonia (COVID-19) is prevalent around the world. We aimed to describe epidemiological features and clinical course in Shanghai. We retrospectively analysed 325 cases admitted at Shanghai Public Health Clinical Center, between January 20 and February 29, 2020.

Production of ingredient type flavoured white enzyme modified cheese.

Enzyme modified white cheese (EMWC) was produced to use as flavouring ingredient. White cheese curd coupled with low fat was hydrolysed using combination of proteinases/peptidase to produce a range of proteolysed products followed by lipolysis. The results revealed that lowering pH 5.

Keap1 Inhibits Metastatic Properties of NSCLC Cells by Stabilizing Architectures of F-Actin and Focal Adhesions.

Low expression of the tumor suppressor Kelch-like ECH-associated protein 1 (KEAP1) in non-small cell lung cancer (NSCLC) often results in higher malignant biological behavior and poor prognosis; however, the underlying mechanism remains unclear. The present study demonstrates that overexpression of Keap1 significantly suppresses migration and invasion of three different lung cancer cells (A549, H460, and H1299). Highly expressed Keap1, compared with the control, promotes formation of multiple stress fibers with larger mature focal adhesion complexes in the cytoplasm where only fine focal adhesions were observed in the membrane under control conditions.

Effects of fragment traits, burial orientation and nutrient supply on survival and growth in Populus deltoides × P. simonii.

Clonal propagations of shoot or root fragments play pivotal roles in adaptation of clonal trees to environmental heterogeneity, i.e. soil nutrient heterogeneity and burials after disturbance.

[Efficacy and adverse effets of nimotuzumab plus palitaxel liposome and carboplatin in the treatment for advanced non-small cell lung cancer].

Objective: To evaluate the efficacy of nimotuzumab combined with palitaxel liposome and carboplatin (LP) regimen for treatment of advanced non-small cell lung cancer (NSCLC), and to observe the changes of tumor markers and toxicities in the treatment. METHODS Forty-one patients with advanced NSCLC were randomly divided into 2 groups: 21 patients in the observation group were treated with nimotuzumab (200 mg per week for 6 weeks), palitaxel liposome 160 mg/m2 and carboplatin (AUC = 6). 20 patients in the control group were given LP regimen.

Pathological impairments induced by interstitial implantation of 125I seeds in spinal canal of banna mini-pigs.

Background: Use a banna mini-pig to set up 125I implantation model, and investigate the consequence of radiation-related impairments.

Methods: In present study, 125I seeds were implanted into spinal canal of T13 level of spine in banna mini-pigs. After operation, the pigs were raised up to 8 months, behavior changes were recorded within this period.

Image encryption by encoding with a nonuniform optical beam in gyrator transform domains.

Based on an optical gyrator transform system, an image encryption algorithm is designed and studied. An original secret image is regarded as the output intensity of the second gyrator transform. A coherent nonuniform optical beam is converted into the input of the first gyrator transform.

Double image encryption by using iterative random binary encoding in gyrator domains.

We propose a double image encryption by using random binary encoding and gyrator transform. Two secret images are first regarded as the real part and imaginary part of complex function. Chaotic map is used for obtaining random binary matrix.

Hyperthermic CO2 pneumoperitoneum induces apoptosis in human colon cancer cells through Bax-associated mitochondrial pathway.

Peritoneal carcinomatosis of colorectal cancer is common and associated with poor prognosis, which poses a serious challenge and satisfactory treatments are urgently needed. Hyperthermic CO2 pneumoperitoneum (HT-CO2) is a new strategy. This study was designed to determine the potential of HT-CO2 against colorectal cancer cells.
