Electromyographic (EMG) signals have gained popularity for controlling prostheses and exoskeletons, particularly in the field of upper limbs stroke patients. However, there is a lack research lower limb area, standardized open-source datasets EMG signals, especially recording data Asian race features, are scarce. Additionally, deep learning algorithms rarely used human motion intention recognition based on EMG, area. In response to these gaps, we present an benchmark dataset with...

Here we show atomically precise CuAg cluster catalysts for CO2 capture utilization, where two functional units are combined into the clusters: metal ligand. Due atomic resolution on total local structures such be achieved, which disentangles imprecise systems permits tracing reaction processes via experiments...

Three N-substituted selenium-bridged diiron complexes [{(μ-SeCH2)2NC6H4R}Fe2(CO)6] (R = 4-NO2, 7; R H, 8; 4-CH3, 9) were firstly prepared as biomimetic models for the Fe–Fe hydrogenases active site.

All new characterized IR, 1H 13C NMR HRMS spectra their molecular...

The allocation of water and land resources (WLRs) has adhered to a system where they "serve as boundaries for each other," posing challenges in satisfying the exacting management requirements these contemporary era. In line with precise predictions future WLRs, optimal framework WLRs was constructed obtain rational configuration scheme. prediction results showed that imbalance between supply demand will intensify Yiluo River Basin. After configuration, shortage, consumption, pollutant...

Developing comprehensive explicit world models is crucial for understanding and simulating real-world scenarios. Recently, Procedural Controllable Generation (PCG) has gained significant attention in large-scale scene generation by enabling the creation of scalable, high-quality assets. However, PCG faces challenges such as limited modular diversity, high expertise requirements, managing diverse elements structures complex scenes. In this paper, we introduce a framework, SceneX, which can...

Abstract An aromatic isocyanide‐substituted diiron complex 5 has been synthesized as a mimic for the active site of Fe‐only hydrogenases. Its structure fully characterized by X‐ray crystallography. The 4‐iodophenylisocyanide ligands in are basal positions and nearly parallel to each other, with π–π stacking interactions. Four isomeric geometries have optimized DFT calculations, electrochemical properties investigated cyclic voltammetry absence presence p ‐toluenesulfonic acid (HOTs)....

Due to its great application potential, large-scale scene generation has drawn extensive attention in academia and industry. Recent research employs powerful generative models create desired scenes achieves promising results. However, most of these methods represent the using 3D primitives (e.g. point cloud or radiance field) incompatible with industrial pipeline, which leads a substantial gap between academic deployment. Procedural Controllable Generation (PCG) is an efficient technique for...

The structures these fully characterized by spectroscopy X‐ray crystallography. IR spectra CO bands – are shifted to higher energy relative those “traditional”...

Abstract Single‐helical or double‐helical structures are common in living organisms. Helical assembly has been found the artificial nanoparticles, but how they do so remains poorly understood. Here, we exploit atomically precise Au 6 Cu bimetallic nanoparticles (or called nanoclusters) as building blocks to construct a single‐helical 12 superstructure an operative path, thereby providing access currently elusive mechanistic pathways. We propose that thermodynamically viable linear‐to‐bent...

Abstract Two stilbazolium derivatives with different counter-anions (Br− and OH− ) have been designed synthesised. Different cause aggregation properties. The reason of this difference was investigated through concentration- temperature-dependent 1H NMR IR spectra. When the counter-anion is , derivative exhibits pronounced scanning electron microscope images xerogels show characteristic gelation morphologies 3D fibrous network structures.

Fluorescein derivatives with thermally activated delayed fluorescence (TADF) show much stronger competition ability and vaster prospects than traditional fluorescein dyes due to their prominent long lifetime. It will be of great significance synthesize more TADF. In this work, compounds DCF-MPYA FL TADF properties were obtained by fine tuning the substituents' structure on basis derivative DCF-MPYM. Their long-lived triplet excited states (21.78 μs, 32.0 μs) proved nanosecond time-resolved...

Federated learning (FL) has emerged as a powerful paradigm for from decentralized data, and federated domain generalization further considers the test dataset (target domain) is absent training data (source domains). However, most existing FL methods assume that labels are provided during training, their evaluation imposes explicit constraints on number of domains, which must strictly match clients. Because underutilization numerous edge devices additional cross-client annotations in real...

Accurate and timely detection repair of pavement cracks is the key to road maintenance. Although crack method based on image semantic segmentation have achieved good results till now, there are still some shortcomings, especially accuracy needing be further improved. We propose a new network for encoder-decoder structure, called MCAMN et, which uses multi-directional convolution module instead conventional feature extraction, solving problem discontinuous incomplete results. MCAMNet...
