Resort workers: the role of social media in connecting youth travellers and mediating the neo-tribe

<div><p>The detection of the singleton attractors is of great significance for the systematic study of genetic regulatory network. In this paper, we design an algorithm to compute the singleton attractors and pre-images of the strong-inhibition Boolean networks which is a biophysically plausible gene model. Our algorithm can not only identify accurately the singleton attractors, but also find easily the pre-images of the network. Based on extensive computational experiments, we show that the computational time of the algorithm is proportional to the number of the singleton attractors, which indicates the algorithm has much advantage in finding the singleton attractors for the networks with high average degree and less inhibitory interactions. Our algorithm may shed light on understanding the function and structure of the strong-inhibition Boolean networks.</p></div

Preparation and Rate Capability of Carbon Coated LiNi_1/3Co_1/3Mn_1/3O₂ as Cathode Material in Lithium Ion Batteries

LiNi1/3Co1/3Mn1/3O2 (NCM) is regarded as a promising material for next-generation lithium ion batteries due to the high capacity, but its practical applications are limited by the poor electronic conductivity. Here, a one-step method is used to prepare carbon coated LiNi1/3Co1/3Mn1/3O2 (NCM/C) by applying active carbon as reaction matrix. TEM shows LiNi1/3Co1/3Mn1/3O2 particles are homogeneously coated by carbon with a thickness about 10 nm. NCM/C delivers the discharge capacity of 191.2 mAh g–1 at 0.5 C (85 mA g–1) with a columbic efficiency of 91.1%. At 40 C (6800 mA g–1), the discharge capacity of NCM/C is 54.6 mAh g–1, whereas NCM prepared through sol–gel route only delivers 13.2 mAh g–1. After 100 charge and discharge cycles at 1 C (170 mA g–1) the capacity retention is 90.3% for NCM/C, whereas it is only 72.4% for NCM. The superior charge/discharge performance of NCM/C owes much to the carbon coating layer, which is not only helpful to increase the electronic conductivity but also contributive to inhibit the side reactions between LiNi1/3Co1/3Mn1/3O2 and the liquid electrolyte

(a) The CPU computational time assumed of the algorithm for finding the singleton attractors of M (M = 500) random genetic regulatory network with N = 50, 〈k〉 = 3, r = 0.4. (b) Semi-logarithmic plot of the averaged CPU computational time (avT) as a function of the network size N. For each N, the value of avT is averaged over M (M ≥ 500) samples. And the error bars denote the range of CPU computational time, while the upper and lower ends of bars represent the maximum and minimum values, respectively. The straight dashed line is linearly fit of the data, indicative of the correlation avT ∝ 1.34N.</p

Interface Chemistry and Defect State Optimization of the ErSmO/InP Heterojunction Modified by ALD-Driven Al₂O₃ Interlayers

In this work, the effects of the atomic-layer deposition (ALD)-derived Al2O3 passivation layer with different growth cycles on the interfacial chemistry and electrical performance of sputtering-driven ErSmO/InP metal oxide semiconductor (MOS) capacitors have been comparatively investigated. Atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) characterization have confirmed that the ALD-driven Al2O3 passivation layer with 20 growth cycles could form a flat dielectric layer and effectively suppress the diffusion of In and P elements at the InP interface. Meanwhile, the ErSmO/Al2O3/InP gate stack with 20 growth cycles exhibited optimal electrical properties, including a large dielectric constant of 37.42, a minimum interface state density (Dit) of 5.43 × 1011 eV–1 cm–2, and a low leakage current of 3.95 × 10–6 A/cm–2. The leakage current conduction mechanisms of InP-MOS capacitors measured at room temperature and low temperature have also been systematically analyzed. Particularly, low-frequency noise (LFN) is used to evaluate trap levels in InP-MOS capacitors. All experimental results have demonstrated that the ErSmO/Al2O3/InP gate stack has potential applications in future ultrahigh-speed and high-frequency microelectronic devices

Three-Dimensional Graphene-Wrapped CoSe₂ Nanowires for High-Performance Asymmetric Supercapacitors

Herein, a three-dimensional graphene (3DG)-coated porous nanowire architecture was developed, which exhibited favorable multiscale and multidimensional porous nanostructures, resulting in an airgel (3DG/CoSe2NWs) with abundant ion transport channels, high specific surface area, and excellent electrical conductivity. This airgel can be used directly as a flexible binder-free electrode with a high specific capacity of 1272 F g–1 at 1 A g–1 and an excellent rate capability of 1156 F g–1 when the current density was increased to 10 A g–1. The prepared asymmetric supercapacitor (3DG/CoSe2NWs//AC) exhibited excellent cycle stability with a coulombic efficiency of 96.19% at 5 A g–1 after 10,000 cycles. The performance of the flexible asymmetric supercapacitor (ASC) device under different bending angles was evaluated, and the discharge stability was confirmed, which indicated its potential in practical applications. Furthermore, two 3DG/CoSe2NWs//AC ASCs (1 cm × 3 cm) connected in series were able to light up an LED lamp, highlighting the promising prospect of the device
