Large Language Models (LLMs) are transforming the landscape of mobile intelligence. Federated Learning (FL), a method to preserve user data privacy, is often employed in fine-tuning LLMs downstream tasks, an approach known as FedLLM. Though recent efforts have addressed network issue induced by vast model size, they not practically mitigated vital challenges concerning integration with devices, such significant memory consumption and sluggish convergence. In response these challenges, this...

Two-stroke spark ignition engines are widely used in Unmanned Aerial Vehicles. Aviation kerosene offers advantages over aviation gasoline due to its higher flash point and lower volatility, making it likely be adopted more the future. However, poor evaporation atomization characteristics of result suboptimal performance, especially engine start-up phase. To explore fitting mixture concentration temperature conditions for achieving better performance kerosene, A series experimental studies...

This article describes and discusses the self-related mechanisms of a general-purpose intelligent system, NARS. system is designed to be adaptive work with insufficient knowledge resources. The system's various cognitive functions are uniformly carried out by central reasoning-learning process following ``non-axiomatic'' logic. logic captures regularities human empirical reasoning, where all beliefs revisable according evidence, meaning concepts grounded in experience. NARS perceives its...

Wang et al. first studied hierarchical quantum information splitting of an arbitrary single-qubit state via the [Formula: see text] as entangled channel. There exists a hierarchy among three receivers far power to recover teleported is concerned. But scheme considered in ideal environment. In this paper, we reinvestigate amplitude-damping and phase-damping noises. The fidelity average are adopted quantify effect noise. It found that they both dependent on coefficients noise parameter....

Reference-frame-independent quantum key distribution (RFI-QKD) has been proven to be very useful and practical under realistic environment. Here, we present a scheme for one-decoy state RFI-QKD based on the work of Rusca et al. [ Appl. Phys. Lett . 112 , 171104 (2018)], carry out investigation its performance experimental conditions.

Superconducting series nanowire single-photon detectors (SNDs) have been used for resolving photon numbers. But it can also exhibit a higher counting rate than single superconducting detector (SNSPD), because the serial architecture allows multiple working in parallel and inductance of each pixel is reduced. In this paper, we found SND could reset fast although whole took much longer time recovering. Therefore, speed an with large kinetic 1.25 μH was characterized compared to standard SNSPD...
