We introduce our first-generation reasoning models, DeepSeek-R1-Zero and DeepSeek-R1. DeepSeek-R1-Zero, a model trained via large-scale reinforcement learning (RL) without supervised fine-tuning (SFT) as preliminary step, demonstrates remarkable capabilities. Through RL, naturally emerges with numerous powerful intriguing behaviors. However, it encounters challenges such poor readability, language mixing. To address these issues further enhance performance, we DeepSeek-R1, which incorporates...
Wireless capsule endoscopy (WCE) offers a feasible noninvasive way to detect the whole gastrointestinal (GI) tract and revolutionizes diagnosis technology. However, compared with wired endoscopies, limited working time, low frame rate, image resolution limit wider application. The progress of this new technology is reviewed in paper, evolution tendencies are analyzed be high resolution, long time. Unfortunately, power supply endoscope (CE) bottleneck. transmission (WPT) promising solution...
We present DeepSeek-V3, a strong Mixture-of-Experts (MoE) language model with 671B total parameters 37B activated for each token. To achieve efficient inference and cost-effective training, DeepSeek-V3 adopts Multi-head Latent Attention (MLA) DeepSeekMoE architectures, which were thoroughly validated in DeepSeek-V2. Furthermore, pioneers an auxiliary-loss-free strategy load balancing sets multi-token prediction training objective stronger performance. pre-train on 14.8 trillion diverse...
Disorders of consciousness (DoC) resulting from severe brain injury present substantial challenges in rehabilitation due to disruptions network connectivity, particularly within the frontal-parietal critical for awareness. Transcutaneous auricular vagus nerve stimulation (taVNS) has emerged as a promising non-invasive intervention; however, precise mechanisms through which it influences cortical function DoC patients remain unclear. This study describes effects taVNS on fronto-parietal...
Alzheimer's disease (AD) is the most serious neurodegenerative worldwide and characterized by progressive cognitive impairment multiple neurological changes, including neuronal loss in brain. However, there are no available drugs to delay or cure this disease. Consequently, replacement therapy may be a strategy treat AD. Osthole (Ost), natural coumarin derivative, crosses blood-brain barrier exerts strong neuroprotective effects against AD vitro vivo. Recently, microRNAs (miRNAs) have...
To investigate the combined effect of transcranial magnetic stimulation (TMS) and direct current on improving lower limb function in stroke patients. Randomized controlled trial. Subacute 169 post-stroke hemiplegia patients were randomly divided into 4 groups (control, stimulation, transcutaneous auricular vagus nerve with stimulation) evaluated using Fugl-Meyer Assessment-Lower Extremity (FMA-LL), Timed Up-and-Go (TUG) test, Modified Barthel Index (MBI), Berg Balance Scale (BBS), gait...

Since non‐linear, it solved an iterative way combining with time‐domain finite‐element method and validated by measurements Inoue's experiments. Furthermore, unconditional stability numerical theoretically proved. The a simplified according to recently Thang et al. , which finite difference time domain (FDTD) used...
Background Transcutaneous auricular vagus nerve stimulation (taVNS) emerges as a promising neuromodulatory technique. However, taVNS uses left ear in stroke survivors with either or right hemiparesis. Understanding its influence on the cortical responses is pivotal for optimizing post-stroke rehabilitation protocols. Objective The primary objective of this study was to elucidate patients presenting hemiparesis and discern potential ramifications upper limb rehabilitative processes. Methods...

Besides, residues poles due...
In order to select a reliable and economical type of transformer on-load tap-changer (OLTC), it is necessary accurately determine the maximum step voltage in process engineering design. Because both configuration operating conditions phase-shifting (PST) are more complicated than those conventional transformers, far harder calculate voltage. The existing calculation methods have shortcomings inadequate accuracy or weak applicability. To solve these problems, based on equivalent circuit PST,...

In this article, we consider quasi-minimax estimation in the linear regression model where some covariates are measured with additive errors. When measurement errors directly ignored minimax risk of resulting estimator can be large. By correcting attenuation propose a penalized quadratic function. A simulation study is conducted to illustrate performance proposed estimators.
