Recently, HTTP has been widely used for the delivery of real-time multimedia content over Internet, such as in video streaming applications. To combat varying network resources rate adaptation is to adapt transmission capacity. A key research problem identify congestion early enough and probe spare In adaptive streaming, this becomes challenging because difficulties differentiating between short-term throughput variations, incurred by TCP control, changes due more persistent bandwidth changes.
Designing structural order in electronically active organic solids remains a great challenge the field of materials chemistry. Now, 2D poly(arylene vinylene)s prepared as highly crystalline covalent frameworks (COFs) by base-catalyzed aldol condensation trimethyltriazine with aromatic dialdehydes are reported. The synthesized polymers emissive (quantum yield up to 50 %), commonly observed their 1D analogues poly(phenylene vinylene)s. inherent well-defined porosity (surface area ca. 1000 m2...
Superionic conductors with ionic conductivity on the order of mS cm-1 are expected to revolutionize development solid-state batteries (SSBs). However, currently available superionic limited only a few structural families such as garnet oxides and sulfide-based glass/ceramic. Interfaces in composite systems alumina lithium iodide have long been identified viable conduction channel, but practical employing interfacial mechanism yet be realized. Here we report novel method that creates...
Abstract Integrating plasmonic nanoparticles into the photoactive metal-organic matrix is highly desirable due to near field enhancement, complementary light absorption, and accelerated separation of photogenerated charge carriers at junction interface. The construction a well-defined, intimate interface vital for efficient carrier separation, however, it remains challenge in synthesis. Here we synthesize bearing interface, composed Ag with silver node via facile one-step approach. effect on...
Transformers have been actively studied for time-series forecasting in recent years. While often showing promising results various scenarios, traditional are not designed to fully exploit the characteristics of data and thus suffer some fundamental limitations, e.g., they generally lack decomposition capability interpretability, neither effective nor efficient long-term forecasting. In this paper, we propose ETSFormer, a novel Transformer architecture, which exploits principle exponential...
We report the first transformation between crystalline vinylene-linked two-dimensional (2D) polymers and cyclobutane-linked three-dimensional (3D) polymers. Specifically, absorption-edge irradiation of 2D poly(arylenevinylene) covalent organic frameworks (COFs) results in topological [2 + 2] cycloaddition cross-linking π-stacked layers 3D COFs. The reaction is reversible, heating to 200 °C leads a cycloreversion while retaining COF crystallinity. resulting difference connectivity manifested...
The black crystalline (aza)triangulene-based covalent organic framework TANG-COF was synthesized from its trinitro-TANG precursor via a one-pot, two-step reaction involving Pd-catalyzed hydrogenation and polycondensation with an aromatic dialdehyde. High crystallinity permanent porosity of the layered two-dimensional (2D) structure were established. rigid, electron-rich trioxaazatriangulene (TANG) building block enables strong π-electron interactions manifested in broad absorptions across...
Abstract Conversion of clean solar energy to chemical fuels is one the promising and up-and-coming applications metal–organic frameworks. However, fast recombination photogenerated charge carriers in these frameworks remains most significant limitation for their photocatalytic application. Although construction homojunctions a solution, it very challenging synthesize them. Herein, we report well-defined hierarchical homojunction based on via facile one-pot synthesis route directed by hollow...
Abstract Red luminescence is found in off‐white tris(iodoperchlorophenyl)methane ( 3I‐PTM H ) crystals which characterized by a high photoluminescence quantum yield (PLQY 91 %) and color purity (CIE coordinates 0.66, 0.34). The emission originates from the doublet excited state of neutral radical R , spontaneously formed becomes embedded matrix. defect can also be deliberately introduced into maintain PLQY with up to 4 % concentration. immobilized iodinated demonstrates excellent...
The low Coulombic efficiency and hazardous dendrite growth hinder the adoption of lithium anode in high-energy density batteries.

Deep learning has been actively studied for time series forecasting, and the mainstream paradigm is based on end-to-end training of neural network architectures, ranging from classical LSTM/RNNs to more recent TCNs Transformers. Motivated by success representation in computer vision natural language processing, we argue that a promising first learn disentangled feature representations, followed simple regression fine-tuning step -- justify such causal perspective. Following this principle,...
