Face Recognition has been studied for many decades. As opposed to traditional hand-crafted features such as LBP and HOG, much more sophisticated can be learned automatically by deep learning methods in a data-driven way. In this paper, we propose two-stage approach that combines multi-patch CNN metric learning, which extracts low dimensional but very discriminative face verification recognition. Experiments show method outperforms other state-of-the-art on LFW dataset, achieving 99.77%...
Different symmetry breaking ways determine various magnetization switching modes driven by spin-orbit torques (SOT). For instance, an applied or effective field parallel to current is indispensable switch with perpendicular anisotropy SOT. Besides of this mode, here we experimentally demonstrate a distinct field-free mode in T-type magnetic system structure MgO/CoFeB/Ta/CoFeB/MgO where layer tilted easy axis was coupled in-plane uniaxial axis. Current orthogonal both axes and thus also...
As an alternative angular momentum carrier, magnons or spin waves can be utilized to encode information and breed magnon-based circuits with ultralow power consumption non-Boolean data processing capability. In order construct such a circuit, it is indispensable design some electronic components both long magnon decay coherence length effective control over transport.

Sequential Gaussian Simulation (SGSIM) as a stochastic method has been developed to avoid the smoothing effect produced in deterministic methods by generating various realizations. One of main issues this technique is, however, an intensive computation related inverse operation solving Kriging system, which significantly limits its application when several realizations need be for uncertainty quantification. In paper, physics-informed machine learning (PIML) model is proposed improve...
With the development of intelligent modern agriculture, strawberry harvesting robots play an increasingly important role in precision agriculture. However, existing vision systems face multiple challenges complex farmland environments, including fruit occlusion, difficulties recognizing fruits at varying ripeness levels, and limited real-time processing capabilities. This study proposes a keypoint detection 3D localization method for utilizing depth camera to address these challenges. By...
Besides spin-transfer torque, spin–orbit torque (SOT) provides us with another electrical way for developing magnetic random access memory (MRAM) based on tunnel junctions (MTJs). By using a CoFeB/Ta/CoFeB T-type structure as synthetic free layer, we have realized magnetic-field-free MTJ switchable by SOT. In the structure, an in-plane CoFeB layer is coupled to perpendicular via Ta spacer. The spacer not only mediates exchange coupling but also generates strong SOT, which drives sharp...
Double barrier heterostructures are model systems for the study of electron tunneling and discrete energy levels in a quantum well (QW). Until now resonant phenomena metallicQW have been observed limited thicknesses (1-2 nm) under which phase coherence is conserved.

The displayed this QWis unprecedented quality because ofa homogenous interface...
We report the Hanle magnetoresistance (HMR) due to spin precession of edge accumulation and interfacial current. Because spin-orbit coupling (SOC), an electric current is accompanied by a transverse current, which builds up at surfaces Pt across YIG/Pt interface. Once magnetic field applied, spins will decrease leads increased resistance via ISHE. Spin relaxation governs HMR from accumulation, while diffusion conversion play important roles in This work provides another method investigate...
SUMMARY Earthquake detection and localization are challenging since the seismic signal usually is noisy microearthquakes hidden in noise. Traditional methods often rely on manually picked phases or computationally intensive algorithms. Inspired by successful application of a deep learning model, ConvNetQuake, detecting locating events, we train an attention-based long short-term memory fully convolutional network (LSTM-FCN) model to improve location accuracy same data set. We use parallel...

The subcellular localization of miRNAs plays a crucial role discovery their biological functions. Although several computational methods based on miRNA functional similarity networks have been presented to identify miRNAs, it remains difficult for these approaches effectively extract well-referenced representations due insufficient...
The use of pretrained models from general computer vision tasks is widespread in remote sensing, significantly reducing training costs and improving performance. However, this practice also introduces vulnerabilities to downstream tasks, where publicly available can be used as a proxy compromise models. This paper presents novel Adversarial Neuron Manipulation method, which generates transferable perturbations by selectively manipulating single or multiple neurons Unlike existing attacks,...
MiRNA subcellular localizations (MSLs) are essential for uncovering and understanding miRNA functions in various biological processes. Several computational methods have been proposed measuring MSL. However, existing only rely on manually crafted features based sequence without considering RNA 3D structure information, most often single-model approaches, which fail to capture the full complexity of systems, further hindering predictive accuracy performance. In this study, we introduce a deep...
