The fine-tuning of Large Language Models (LLMs) is pivotal for achieving optimal performance across diverse downstream tasks. However, while full delivers superior results, it entails significant computational and resource costs. Parameter-Efficient Fine-Tuning (PEFT) methods, such as LoRA, address these challenges by reducing the number trainable parameters, but they often struggle with rank adjustment efficiency task-specific adaptability. We propose Triangular Adaptive Low-Rank Adaptation...
Evaluation of key nodes is a hot issue in social networks. Existing research primarily evaluates the importance networks based on centrality metrics, neglecting node's own attributes. After analyzing topology attributes and basic nodes, this article proposes evaluation method for networks, which analytic hierarchy process (AHP) improved Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR), termed AE-VIKOR. Considering global attributes, local positional three metrics are...

Farber and Keil [Algorithmica, 4 (1989), pp. 221–236] presented an $O(n^3 )$-time algorithm for finding a minimum-weight dominating set in permutation graphs. This result was improved to $O(n^2 \log ^2 n)$ by Tsai Hsu [SIGAL ’90 Algorithms, Lecture Notes Computer Science, Springer-Verlag, New York, 1990, 109–117] $O(n(n + m)$ the authors of this paper [Inform. Process. Lett., 37 (1991), 219–224], respectively. In paper, we introduce new faster that takes only $O(n time solve same problem,...
Ranking a tree is defined as mapping rho of the nodes to set (1, 2, . .) such that if there path from u v and (u)= (v) then node w on (w)> (u). The highest number assigned called rank mapping. A with smallest optimal ranking. best known serial algorithm takes O(n) time for However, problem finding ranking appears be highly sequential. It remains open whether it in NC. paper proposes fast parallel approximate trees using O(logn) steps n/sup 2/ processors CRCW PRAM an efficient O(log/sup 2/n)...
Purpose: The planar average equilibrium dose of CT is measured using the methodology suggested by AAPM report No. 111, and compared with traditional weighted estimate new proposed equal estimate.

Fine-tuning techniques based on Large Pretrained Language Models (LPLMs) have been proven to significantly enhance model performance a variety of downstream tasks and effectively control the output behaviors LPLMs. Recent studies proposed numerous methods for fine-tuning small number parameters open-source LPLMs, reducing demand computational storage resources. Among these, reparameterization represented by LoRA (Low-Rank Adaptation) gained popularity. We find that although these perform...

Photomultiplier tubes (PMTs) are essential in xenon detectors like PandaX, LZ, and XENON experiments for dark matter searches neutrino properties measurement. To minimize PMT-induced backgrounds, stringent requirements on PMT radioactivity crucial. A novel 2-inch low-background R12699 has been developed through a collaboration between the PandaX team Hamamatsu Photonics K.K. corporation. Radioactivity measurements conducted with high-purity germanium detector show levels of approximately...
Purpose: To determine and compare the entrance skin doses from routine CT brain perfusion protocols on various Siemens scanners. Methods: Four scanners were surveyed using their protocol (see supporting document): two Sensation 64‐slice (EC‐CT‐2 IP‐CT‐2), one Definition Dual Source (64‐slice), Flash (128‐slice). The dose was measured a RANDO® anthropomorphic phantom Landauer optically stimulated luminescent (OSL) nanoDot dosimeters. We performed scan three times each scanner with OSL...
