The traveling salesman problem (TSP) has been an extensively studied problem for a long time and has attracted a considerable amount of research effort. Ant colony system (ACS) algorithm is better method to solve TSP. This paper presents HACS-LS, a hybrid ant colony optimization approach combined with an improvement local search algorithm, applied to traveling salesman problem. The improvement ...

We study the behavior of a Quality of Service (QoS) routing scheme in which connection requests can be assigned to one of k alternative paths from the source to the destination. The multiple–path routing compensates for the inaccurate link state (LS) information. It is found that the frequency of LS dissemination is not the only factor to influence performance. For large LS update periods, the ...

Liver stiffness (LS), assessed using transient elastography (TE), and (FIB-4) can both estimate the risk of developing hepatocellular carcinoma (HCC). We compared prognostic performances of LS and FIB-4 to predict HCC development in patients with chronic hepatitis B (CHB).Data from 1308 patients with CHB, who underwent TE, were retrospectively analyzed. FIB-4 was calculated for all patients. Th...

Liquid smoking emerges as a potential substitution for traditional smoking method in preserving proteinaceous foods. The study is aimed to investigate antibacterial activity of coconut shell liquid smoke (CSLS) and potential application of CS-LS on fish ball preservation. Minimum Inhibitory Concentration (MIC) of CS-LS is determined with broth dilution method against Pseudomonas aeruginosa and ...

Learning strategy (LS) fusion is our previous work in reinforcement learning (RL) framework. LS fusion fuses multiple LSs, such as transfer learning, for a single task of a robot. This paper introduces two LSs into LS fusion: an LS to learn a dynamics and a reward models, and an LS using a model-based RL method. Especially, we propose to use the MixFS dynamics model which is also our previous w...

The paper presents a model for simulating the protein folding process in silico. The two-step model (which consists of the early stage-ES and the late stage-LS) is verified using two proteins, one of which is treated (according to experimental observations) as the early stage and the second as an example of the LS step. The early stage is based solely on backbone structural preferences, while t...

Levosimendan (LS), a Ca(2+) sensitizer, is presently limited to i.v. administration. The dose-related pharmacodynamic effects of newly developed oral LS remain undetermined. We assessed the dose-response relationship of oral LS in nine normal and seven pacing-induced heart failure (HF), conscious, chronically instrumented mongrel dogs. Animals received a placebo capsule on day 1, and then LS wa...

about release-modulating receptors at noradrenergic axon terminals. Receptors for angiotensin, acetylcholine, prostaglandins, opioids, and adrenergic agents are discussed separately, followed by general problems such as the cellular mechanism of modulation and the general significance of presynaptic receptors. [The SCV’ indicates that this paper has been cited in over 1,035 publications, making...
