Deep Learning-based framework for Autism functional MRI Image Classification

The purpose of this paper is to introduce deep learning-based framework LeNet-5 architecture and implement the experiments for functional MRI image classification of Autism spectrum disorder. We implement our experiments under the NVIDIA deep learning GPU Training Systems (DIGITS). By using the Convolutional Neural Network (CNN) LeNet-5 architecture, we successfully classified...

Statistical models for meal-level estimation of mass and energy intake using features derived from video observation and a chewing sensor

Accurate and objective assessment of energy intake remains an ongoing problem. We used features derived from annotated video observation and a chewing sensor to predict mass and energy intake during a meal without participant self-report. 30 participants each consumed 4 different meals in a laboratory setting and wore a chewing sensor while being videotaped. Subject-independent...

An Evolutionarily Conserved Structural Platform for PRC2 Inhibition by a Class of Ezh2 Inhibitors

Polycomb repressive complex 2 (PRC2) mediates trimethylation of histone H3K27 (H3K27me3), an epigenetic hallmark for repressed chromatin. Overactive mutants of the histone lysine methyltransferase subunit of PRC2, Ezh2, are found in various types of cancers. Pyridone-containing inhibitors such as GSK126 compete with S-adenosylmethionine (SAM) for Ezh2 binding and effectively...

Effect of the Preexisting Fissure with Different Fillings in PMMA on Blast-Induced Crack Propagation

In order to study the dynamic crack propagation law in fissured rock under the different fillings, a borehole with 7 mm diameter was processed in the center of a polymethyl methacrylate (PMMA) specimen. The preexisting fissure with different angles (θ = 0°, 45°, and 90°) and different distances (L = 20, 30, 40, 50, and 60 mm) was prefabricated around the borehole. Air, soil, and...

Different memory patterns of digits: a functional MRI study

Psychological investigations and functional imaging technology have been used to describe neural correlations of different types of memory with various stimuli. Memory with limited storage capacity and a short retention time can be classified as short-term memory (STM) while long-term memory (LTM) can be life-long without defined capacity. To identify brain activation pattern...

Practices and knowledge of female gynecologists regarding contraceptive use: a real-world Chinese survey

There is no evidence of the practices of obstetricians and gynecologists (OB/GYNs) regarding contraceptive use and determinants influencing contraceptive choices, including emergency methods such as combined oral contraceptives (COCs) and levonorgestrel intrauterine system (LNGIUS). This survey determines the practices and knowledge among Chinese female OB/GYNs regarding modern...

Enhanced Photovoltaic Properties in Sb2S3 Planar Heterojunction Solar Cell with a Fast Selenylation Approach

Poor thermostability of Sb2S3 in vacuum hinders the possibility of achieving high-quality crystalline films. In order to enhance the photovoltaic properties of Sb2S3 planar heterojunction solar cells, a selenylation-based post-treatment approach has been employed. Selenylation performed over 15 min on the Sb2S3 film resulted in an enhancement in the conversion efficiency from ~ 0...

Optimal Disturbance Rejection with Zero Steady-State Error for Nonlinear Vehicle Suspension Systems under Persistent Road Disturbances

The road disturbance rejection problem for vehicle active suspension involving the nonlinear characteristics is researched in this paper. A continuous-time state space of nonlinear vehicle active suspension is established first, in which the road disturbance is generated from the output of an introduced exosystem based on the ground displacement power spectral density. After that...

Effects of cow’s milk beta-casein variants on symptoms of milk intolerance in Chinese adults: a multicentre, randomised controlled study

A major protein component of cow’s milk is β-casein. The most frequent variants in dairy herds are A1 and A2. Recent studies showed that milk containing A1 β-casein promoted intestinal inflammation and exacerbated gastrointestinal symptoms. However, the acute gastrointestinal effects of A1 β-casein have not been investigated. This study compared the gastrointestinal effects of...
