A simple and effective way to make DNA patchy particles is reported. small patch of strands "stamped" from a gold surface onto colloidal different sizes by streptavidin-biotin bonds. These provide direction-selective thermoreversible interactions, hence can lead unique assembly protocols structures controlled temperature.

The specificity and thermal reversibility of DNA interactions have enabled the self-assembly crystal structures, self-replicating materials colloidal molecules. Grafting onto liquid interfaces emulsions leads to exciting new architectural possibilities due mobility ligands patches they form between bound droplets. Here we show that size number these adhesion (valency) can be controlled. Valence 2 flexible polymers emulsion droplets, while valence above 4 rigid droplet networks. A simple...

Spiking neural networks (SNNs) are bio-inspired with asynchronous discrete and sparse characteristics, which have increasingly manifested their superiority in low energy consumption. Recent research is devoted to utilizing spatio-temporal information directly train SNNs by backpropagation. However, the binary non-differentiable properties of spike activities force trained suffer from serious gradient vanishing network degradation, greatly limits performance prevents them going deeper. In...

This letter proposes a handover strategy for the links between satellites and gateway stations based on weighted bipartite graph in low earth orbit (LEO) satellite networks. To maximize overall communication quality balance load of networks, maximum weight matching method is investigated by using Kuhn-Munkres (KM) algorithm. Then, we enhance KM algorithm, which more suitable scene handover, employ multiple-input multiple-output (MIMO) technology to further improve quality. Finally, derive...

As a new green energy‐harvesting technology, the electrification mechanism and output performance of triboelectric nanogenerators (TENGs) have become research focuses difficulties.

DNA is increasingly used as an important tool in programming the self-assembly of micrometer- and nanometer-scale particles. This largely due to highly specific thermoreversible interaction cDNA strands, which, when placed on different particles, have been bind precise pairs aggregates crystals. However, functionalized particles will only reach their true potential for particle assembly each can address many kinds Indeed, specifying all bonds force a particular designed structure. In this...

DNA-functionalized particles are promising for complex self-assembly due to their specific controllable thermoreversible interactions. However, there has been little work on the kinetics and aggregation rate, which depend rate of particle encounters probability that an encounter results in sticking. In this study, we investigate theoretically experimentally times micron-scale as a function DNA coverage salt concentration. Our 2-$\ensuremath{\mu}$m colloids accommodate up 70 000 strands. For...

Human brain can effectively integrate visual and auditory information. Dynamic Vision Sensor (DVS) Audio (DAS) are event-based sensors imitating the mechanism of human retina cochlea. Since record input as asynchronous discrete events, they inherently suitable to cooperate with spiking neural network (SNN). Existing works SNNs for processing events mainly focus on unimodality, however, audiovisual multimodal still limited. In this paper, we propose an end-to-end network. The consists...

Light trapping, caused by the introduction of metallic nanoparticles, has been demonstrated to enhance photo-absorption in GaAs solar cells. In this study, we successfully synthesized gold nanostar thin film with hot spots and obtained a notable improvement power conversion efficiency (PCE) single-junction three-junction high-performance cells incorporating poly (3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) layer, which enables much stronger light trapping capability...

Alphabetical writing systems use letters that are closely related to speech record speech. However, the glyphs of Chinese characters do not directly express sounds, and ideographic mechanism between their meanings is transparent. We analysed relationship nine thousand found combination elements in glyph constructs certain imagery, this imagery a psychological representation experience informing concept character, so meaning ideographically connected. In other words, formation small number...

While one-dimensional convolutional neural networks (1D-CNNs) have been empirically proven effective in time series classification tasks, we find that there remain undesirable outcomes could arise their application, motivating us to further investigate and understand underlying mechanisms. In this work, propose a Temporal Convolutional Explorer (TCE) explore the learning behavior of 1D-CNNs from perspective frequency domain. Our TCE analysis highlights deeper tend distract focus...

Abstract Low earth orbit constellation satellite communication has the characteristics of low propagation delay, path loss, launch cost and wide range applications. Due to orbital altitude short period satellites, relative position between satellites gateway stations changes fast. As a result, links need be switched continuously. Based on minimum handover frequency algorithm, this paper considers balance workloads, proposes load balanced strategy. In proposed strategy, joint optimization...

We have discovered a new type of interaction between micro- or nanoscale particles that results from the entanglement strands attached to their surfaces. Self-complementary DNA single on particle can hybridize form loops. A similar proximal its loops catenate with those first. Unlike conventional thermodynamic interparticle interactions, catenation is strongly history and protocol dependent, allowing for nonequilibrium assembly. The interactions be controlled by an interesting combination...

Split fabrication is a promising approach to security against attacks by untrusted foundries. While existing split methods consider the overhead of conventional objectives such as wirelength and timing, they mostly neglect manufacturability - an unavoidable challenge in nanometer technologies. Observing that can be addressed synergistic manner, this work introduces routing techniques simultaneously improve both terms either Chemical Mechanical Planarization (CMP) uniformity or Self-Aligned...
