Swift advancements in large language model (LLM) technologies lead to widespread research and applications, particularly integrating LLMs with auxiliary tools, known as tool-using LLM agents. However, amid user interactions, the transmission of private information both tools poses considerable privacy risks users. In this paper, we delve into current privacy-preserving solutions for outline three pivotal challenges agents: generalization open-source closed-source compliance requirements,...
<p>Air pollution is a pressing concern in China, particularly its adverse effects on vulnerable populations such as children and adolescents. This study aimed to elucidate the disease burden adolescents attributable air geographical areas across China from 1990 2019. We used Global Burden of Diseases, Injuries, Risk Factors Study 2019 methodology estimate 33 including provinces, autonomous regions, municipalities, special administrative regions. In 2019, approximately 10,511 childhood...
Enhancing the oxygen reduction reaction (ORR) activity and stability of fuel cell cathode electrocatalysts reducing their costs are critical. In response to this need, Fe, B, N co-doped hollow mesoporous carbon materials were prepared by a simple chemical doping one-step pyrolysis method using ZIF-8 as precursor. The results showed that optimized catalyst displayed higher limiting current density (6.154 mA cm-2) half-wave potential (0.859 V), which significant enhancement compared with Pt/C...
Abstract Contaminants that entered the streambed during previous surface water pollution events can be released to stream, causing secondary of stream and impacting its eco‐environmental condition. By means laboratory experiments numerical simulations, we investigated density effects on release solute from periodic bedforms. The results show upper is driven by bedform‐induced convection, generally inhibit lower streambed. Density gradients modify pore flow patterns form circulating flows in...
Asymmetric optical transmission has recently been demonstrated using Lorentz‒reciprocal devices with patterned photonic structures of linear materials by breaking spatial inversion symmetry. However, it is a huge challenge to fabricate such due their sophisticated multilayer configurations. In this letter, we show that simple single‒layer dielectric gradient metasurface (GM) enables high-efficiency asymmetric under the oblique incidence. The underlying mechanism ascribed unbalanced...
Despite the outstanding performance of Large language models (LLMs) in diverse tasks, they are vulnerable to jailbreak attacks, wherein adversarial prompts crafted bypass their security mechanisms and elicit unexpected responses.Although attacks prevalent, understanding underlying remains limited. Recent studies have explain typical jailbreaking behavior (e.g., degree which model refuses respond) LLMs by analyzing representation shifts latent space caused or identifying key neurons that...
Despite the promising advances in deepfake detection on current datasets, detecting visual deepfakes real-world scenarios (e.g., videos and live streaming YouTube) remains a challenge due to inherent quality degradation such as unpredictable compression employed by social media platforms. Such perturbs discernible forgery clues diminishes effectiveness of methods, raising critical safety concern misuse faces scenarios. In this paper, we aim understand impacts robustness detection....
Consensus mechanism is the underlying technology of blockchain and rule to maintain normal operation blockchain. Commonly used consensus mechanisms public chain include POW, POS, DPOS, BFT those mixed with many other mechanismsBy comparing characteristics several mechanisms, DPOS can generate more blocks less computing power, use BLS (Boneh-Lynn-Shacham) signatures for verification in process transaction create a new mechanism..Combined mechanism, this paper deeply explored how improve...
Abstract The catalytic performance of Perfluorosulfonic acid resin (PFSA), a solid superacid, was studied in the benzylation 1,3‐dicarbonyl compounds with benzylic alcohols. PFSA‐catalyzed reactions could proceed smoothly to provide products under solvent‐free conditions or toluene and dichloromethane, which gave moderate excellent yields. Due its high chemical stability, PFSA quite stable reaction be recovered at least eight times without significant reduction effect. Moreover, this...
Purpose: The purpose of this study is to present our surgical experience with symptomatic congenital cystic adenomatoid malformations (CCAMs) in neonates. Methods: medical records neonates who underwent surgery for CCAM from 2010 2020 were retrospectively reviewed. Results: Of 24 cases, 10 involved open resection, and 14 thoracoscopic resection. Four cases CCAMs located the upper or middle lobes lobectomy, 20 lung-preserving wedge resection lower lobe. Between two groups, there was no...
