Micro- and nanoscale tubular structures can be formed by strain-induced self-rolled-up nanomembranes. Precision engineering of the shape and dimension determines the performance of devices based on this platform for electronic, optical, and biological applications. A transient quasi-static finite element method (FEM) with moving boundary conditions is proposed as a general approach to design di...

In distributed applications, multiple objects are cooperated to achieve some objectives. The objects may su er from kinds of faults. If some object o is faulty, o is rolled back to the checkpoint and objects which have received messages from o are also required to be rolled back. In this paper, we de ne in uential messages whose receivers are required to be rolled back if the senders are rolled...

Sir, Abnormal keratinization of the distal part of the hair follicle can prevent emergence of the growing hair from the follicle and lead to spiral growth within a hyperkeratotic papule, socalled ``rolled hairs'' (1). Rolled hairs have been reported in patients with keratosis pilaris (1), neurodermatitis (1), palmoplantar keratoderma (2), and hypertrichosis (3). The disorder has also been assoc...

OBJECTIVE The effects of particle size of processed barley grain, enzyme addition and microwave treatment on in vitro dry matter (DM) disappearance (DMD), gas production and fermentation pH were investigated for feedlot cattle. METHODS Rumen fluid from four fistulated feedlot cattle fed a diet of 860 dry-rolled barley grain, 90 maize silage and 50 supplement g/kg DM was used as inoculum in 3 ...

Surface defect classification plays an important role in the assessment of production status and analyzing possible causes hot rolled strip steel. It is extremely challenging owing to rare occurrence various appearances defects. In this work, improved deep learning model proposed solve problem poor accuracy when only a few labeled samples can be available. Different from most inductive small-sa...

A new real time in-situ scattering method to study texture evolution kinetic is exposed. The technique is adapted from an existing set up used at the Institut Laue-Langevin neutron facility to check monochromators. It uses a white hard X ray beam and works in transmission geometry. The 2D detector allows to follow recrystallization phenomena. A study of the annealing behavior of copper-nickel a...

This work investigated the microstructure and elevated-temperature (400-475C) tensile and tensile-creep deformation behavior of a powder metallurgy (PM) rolled Ti-6Al-4V-1B(wt.%) alloy. The PM rolled Ti-6Al-4V-1B alloy exhibited a duplex microstructure, and it did not exhibit a strong α-phase texture compared with the PM extruded Ti-6Al-4V-1B alloy. The PM rolled Ti6Al-4V-1B alloy exhibited gre...

It has great significance to research the dynamical reliability probability of rolling mill rolls system for improving its stochastic dynamical reliability and products quality rolled. The fifth-octave vertical vibration stochastic dynamical model of rolls system was established, and the pseudo-excitation method was used to obtain the power spectral density and the variance variation characteri...

This study was aimed to explain the influence of surface roughness of the drawbead on non-symmetry deep drawing cold rolled steel sheet to improve the drawability of cold rolled steel sheet. The variables used in this study included semi-circle drawbead with 3 levels of surface roughness which are 6.127 μm Ra, 0.963 μm Ra and 0.152 μm Ra and cold rolled steel sheet according to 3 grades of the ...

Proper synaptic function in neural circuits requires precise pairings between correct pre- and post-synaptic partners. Errors in this process may underlie development of neuropsychiatric disorders, such as autism spectrum disorder (ASD). Development of ASD can be influenced by genetic factors, including copy number variations (CNVs). In this study, we focused on a CNV occurring at the 16p11.2 l...
