Importance Previous studies have demonstrated the advantages of short-term histopathological outcomes and complications associated with transanal total mesorectal excision (TME) compared laparoscopic TME. However, long-term oncological TME remain ambiguous. This study aims to compare 3-year disease-free survival Objective To evaluate between in patients rectal cancer. Design, Setting, Participants randomized, open-label, noninferiority, phase 3 clinical trial was performed 16 different...

We present a method for active inference with partial observations in stochastic systems through incentive design, also known as the leader-follower game. Consider leader agent who aims to infer follower agent's type given finite set of possible types. Different types followers differ either dynamical model, reward function, or both. assume can partially observe follower's behavior system modeled Markov decision process, which takes an optimal policy maximize total reward. To improve...

We prove a continuation criterion for the free boundary problem of three-dimensional incompressible ideal magnetohydrodynamic (MHD) equations in bounded domain, which is analogous to theorem given Beale, Kato, and Majda [Commun. Math. Phys. 94, 61–66 (1984)]. combine energy estimates our previous works [C. Hao T. Luo, Arch. Ration. Mech. Anal. 212(3), 805–847 (2014)] on MHD some Ginsberg [SIAM J. 53, 3366–3384 (2021); arXiv:1811.06154] show that solution can be continued as long curls...

The problem of reward design examines the interaction between a leader and follower, where aims to shape follower's behavior maximize leader's payoff by modifying function. Current approaches rely on an accurate model how follower responds modifications, which can be sensitive modeling inaccuracies. To address this issue sensitivity, we present solution that offers robustness against uncertainties in including 1) breaks ties presence nonunique best responses, 2) inexact knowledge perceives...

Mixture-of-Experts (MoE) has been demonstrated as an efficient method to scale up models. By dynamically and sparsely selecting activated experts, MoE can effectively reduce computational costs. Despite the success, we observe that many tokens in models have uncertain routing results. These nearly equal scores for choosing each expert, demonstrate this uncertainty lead incorrect selections. Inspired by Global Workspace Theory (GWT), propose a new fine-tuning method, GW-MoE, address issue....

This paper focuses on the global well-posedness of Oberbeck–Boussinesq approximation for unsteady motion a drop in another bounded fluid separated by closed interface with surface tension. We assume that initial state is close to ball BR same volume as drop, and boundary small perturbation BR. To begin, we introduce Hanzawa transformation an added barycenter point obtain linearized fixed domain. From there, establish time-weighted estimates solutions shifted equation using maximal Lp–Lq...

The scaling of large language models (LLMs) has revolutionized their capabilities in various tasks, yet this growth must be matched with efficient computational strategies. Mixture-of-Experts (MoE) architecture stands out for its ability to scale model size without significantly increasing training costs. Despite advantages, current MoE often display parameter inefficiency. For instance, a pre-trained MoE-based LLM 52 billion parameters might perform comparably standard 6.7 parameters. Being...

This paper aims to establish the global well-posedness of free boundary problem for incompressible viscous resistive magnetohydrodynamic (MHD) equations. Under framework Lagrangian coordinates, a unique solution exists in half-space provided that norm initial data critical homogeneous Besov space $\dot{B}_{p, 1}^{-1+N/p}(\mathbb{R}_{+}^N)$ is sufficiently small, where $p \in [N, 2N-1)$.

Molecular dynamics simulations have emerged as a fundamental instrument for studying biomolecules. At the same time, it is desirable to perform of collection particles under various conditions in which molecules can fluctuate. In this paper, we explore and adapt soft prompt-based learning method molecular tasks. Our model remarkably generalize unseen out-of-distribution scenarios with limited training data. While our work focuses on temperature test case, versatility approach allows...
