In this study, a lithium-rich 0.4Li2MnO3.0.6LiNi1/3Co1/3Mn1/3O2 nanotube layered cathode synthesized by novel electrospinning is reported, and the effects of temperature on the electrochemical performance and morphologies are investigated. The crystal structure is characterized by X-ray diffraction patterns, and refined by two sets of diffraction data （R-3m and C2/m）. Refined crystal structure is 0.4Li2MnO3.0.6LiNi1/3COl/3Mn13O2 compos- ite. The inductively coupled plasma optical emission spec- trometer and thermogravimetric and differential scanning calorimetry analysis measurement supply reference to opti- mize the calcination temperature and heat-treatment time. The morphology is characterized by scanning and high- resolution transmission electron microscope techniques, and the micro-nanostructured hollow tubes of Li-rich 0.4Li2MnO3-0.6LiNil/3COl/3Mn1/3O2 composite with outer diameter of 200-400 nm and the wall thickness of 50-80 nm are synthesized successfully. The electrochemical evaluation shows that 0.4Li2MnO3.0.6LiNi1/3Cov3Mn1/3O2 sintered at 800 ℃ for 8 h delivers the highest capacity of the first dis- charge capacity of 267.7 mAh/g between 2.5 V and 4.8 V at 0.1C and remains 183.3 mAh/g after 50 cycles. The electro- spinning method with heat-treatment to get micro-nanos- tructured lithium-rich cathode shows promising application inlithium-ion batteries with stable electrochemical performance and higher C-rate performance for its shorter Li ions transfer channels and stable designed structure.

By using the approach of immunofluorescence staining with an antibody against 5-methylcytosine (5MeC), the present study detected the DNA methylation patterns of bovine zygotes and preimplanta-tion embryos derived from oocyte in vitro maturation (IVM), in vitro fertilization (IVF) and embryo in vitro culture (IVC). The results showed that: a) paternal-specific demethylation occurred in 61.5% of the examined zygotes, while 34.6% of them showed no demethylation; b) decreased methylation level was observed after the 8-cell stage and persisted through the morula stage, however methylation levels were different between blastomeres within the same embryos; c) at the blastocyst stage, the methyla-tion level was very low in inner cell mass, but high in trophectoderm cells. The present study suggests, at least partly, that IVM/IVF/IVC may have effects on DNA methylation reprogramming of bovine zygotes and early embryos.

Sox2, one of genes which express in embryonic stem (ES) cells, plays an important role in self renewal of ES cells, and is used to make induced pluripotent stem (iPS) cells. In this study, we subcloned mouse (Mus muscules) full-length Sox2 cDNA and inserted Sox2 into pET-41a expression vector. Then the recombinant vector was transformed into Escherichia coli BL21 (DE3) cells to express Sox2 fusion protein. The expressed products were identified by Western blot using anti-GST antibody. The result indicated that the size of Sox2 fusion protein was in 61 kD. And the protein was recovered from the SDS-PAGE. And we used the sox2 fusion protein to prepare polyclonal antibody. The Dot blotting result showed that the anti-Sox2 antiserum had 1∶12,800 titers. The antibody will be useful for studying the function of Sox2 and its role in ES cell self-renewal.

Optical neural networks (ONNs) offer a promising solution for high-performance, energy-efficient artificial intelligence hardware by leveraging the parallelism and speed of light. However, the large-scale implementation of ONNs remains challenging due to the bulky footprint and complex control of optical synapses. In this work, we propose and simulate a plasmonic polarized synaptic architecture that overcomes the diffraction limit and enables ultra-compact ONNs. By tuning the polarization state of incident light, the optical transmittance through each plasmonic unit can be dynamically adjusted to represent a synaptic weight. Our plasmonic structures, with features as small as 40 nm, operate well below this limit in the visible spectrum (400–750 nm). Compared with diffraction and interference-based circuit designs, our proposed method achieves a substantial reduction in synaptic density by factors of 150000-fold and 1500-fold, respectively. Furthermore, we successfully demonstrate a proof-of-concept plasmonic ONN applied to the Canadian Institute for Advanced Research—10classes (CIFAR-10) dataset using a Visual Geometry Group network with 16 layers (VGG16) model. After training for 80epochs, the network achieves an accuracy of 93%. The polarization-tunable plasmonics paves the way towards scalable ONNs for next-generation artificial intelligence (AI) accelerators and smart sensors.
