Jidong Liu,Yuanchen Wu,Meile Le 한국HCI학회 2024 한국HCI학회 학술대회 Vol.2024 No.1

This study explores the interaction methods of smart homes in sleep scenarios based on user needs, aiming to enhance user interaction experience with a user-centric interaction philosophy, and shift the development direction of smart homes from technologydriven to consumer needs-driven. The results indicate that in the sleep aid stage, Focused Interaction is the primary method, supported by Peripheral and Implicit Interactions. During the sleep stage, Implicit Interaction is the main method, supplemented by Peripheral and Focused Interactions. In the awakening stage, a foundation of Peripheral and Implicit Interactions with minimal Focused Interaction aligns more closely with consumer habits. This model can prevent the blind development of new interaction methods in smart homes within sleep scenarios, reducing the occurrence of unnecessary or unreasonable human-machine interactions.

Spodoptera exigua has developed very high resistance to pyrethroid insecticides; however, the mode-of-action target of pyrethroids has not been studied, and the mechanism for target resistance remains elusive in this insect. In this study the resistance level of a field collected population from Huizhou, China was assayed with leaf-dip method and further selected in laboratory. The transcripts of voltage-gated sodium channel gene from S. exigua were cloned and analyzed for the structural characteristics, the relative expression levels of transcripts were measured by quantitative RT-PCR. Finally, detection of the point mutations was performed. The bioassay indicated that Huizhou population had developed 309.5-fold resistance to lambda-cyhalothrin, and the selection in laboratory led to the resistant strain (HZ14-sel) with increased resistance of 423-fold. Nine transcripts of sodium channel with 4517–6149 bp nucleotides were identified from S. exigua, among which only one transcript (SeNav4) encode the functional protein with complete domains, and other eight transcripts were observed to lost some transmembrane segments. The L834F mutation in IIS6 corresponding for the typical kdr mutation “L1014F”, was detected in 50% individuals of HZ14-sel strain. These results suggested that lambda-cyhalothrin resistance is associated with point mutations and expression level changes of sodium channel transcripts in HZ14-sel strain.

The traditional fatigue design of accessories attached to a train body does not consider welding residual stress for fatigue life prediction of welded structures during the design stage, thereby resulting in insufficient fatigue strength for local welded parts. The power spectral density of random excitation caused by rail irregularity from American six-level spectrums was obtained in this paper. Through welding thermal elastoplastic theory combined with ellipsoid heat source model, a numerical simulation for welding residual stress production and distribution of a train buffer beam was conducted. In accordance with the coupling stress component, the fatigue performance of a train buffer beam under random loads was evaluated by the AA6082 welded joint S–N curve, whose lifetime did not satisfy design requirements. Then, the surrogate model of a train buffer beam for anti-fatigue optimization design was constructed based on the response surface method. The fatigue life of the optimized train buffer beam increased by two orders with the use of the genetic algorithm to find the optimal solution in global variables.

Background Several studies have demonstrated that circulating tumor DNA (ctDNA) can be used to predict the postoperative recurrence of several cancers. However, there are few studies on the use of ctDNA as a prognosis tool for gastric cancer (GC) patients. Objective This study aims to determine whether ctDNA could be used as a prognostic biomarker in GC patients through multigene-panel sequencing. Methods Using next-generation sequencing (NGS) Multigene Panels, the mutational signatures associated with the prognosis of GC patients were identified. We calculated the survival probability with Kaplan–Meier and used the Log-rank test to compare survival curves between ctDNA-positive and ctDNA-negative groups. Potential application of radiology combined with tumor plasma biomarker analysis of ctDNA in GC patients was carried out. Results Disease progression is more likely in ctDNA-positive patients as characterized clinically by a generally higher T stage and a poorer therapeutic response (P < 0.05). ctDNA-positive patients also had worse overall-survival (OS: P = 0.203) and progression-free survival (PFS: P = 0.037). The combined analysis of ctDNA, radiological, and serum biomarkers in four patients indicated that ctDNA monitoring can be a good complement to radiological and plasma tumor markers for GC patients. Kaplan–Meier analysis using a cohort of GC patients in the TCGA database showed that patients with CBLB mutations had shorter OS and PFS than wild-type patients (OS: P = 0.0036; PFS: P = 0.0027). Conclusions This study confirmed the utility and feasibility of ctDNA in the prognosis monitoring of gastric cancer.

The findings reveal that AI not only elevates the efficiency and fidelity of the design process but also significantly improves communication between designers and clients. This underscores the potential of AI in fostering a novel, innovative design approach, one that is adaptive and responsive to the evolving trends in the market, thereby setting a new standard in the realm of visual design.

An Optimal Investment Portfolio for BOT Freeway Projects from the Perspective of Transportation and Construction Enterprises

Hui Sun,Yingzi Liang,Yuning Wang,Xiangcheng Liu,Jidong Chen 대한토목학회 2021 KSCE JOURNAL OF CIVIL ENGINEERING Vol.25 No.10

Build-Operate-Transfer (BOT) plays a significant part in promoting the construction of freeways. Due to the long construction period and large investment, many uncertain factors affect the inputs, outputs, and returns of freeway projects during the construction and operation periods. For project investments, funds, returns, risks, and other relevant factors of the projects should be considered, evaluated, and balanced. This paper presents the perception of net present value (NPV) at risk to solve the uncertain financing parameters of BOT freeway project. This paper analyses the critical indicators of BOT project investment, and establishes an investment portfolio decision-making model for BOT freeway projects to maximize the NPV of the project portfolio. Based on the proposed model, this paper calculates the optimal investment portfolio with real constraints from financial perspective. At last, an investment portfolio case study is also provided to test the proposed model.

China has a long history of sheep (Ovis aries [O. aries]) breeding and an abundance of sheep genetic resources. Knowledge of the complete O. aries mitogenome should facilitate the study of the evolutionary history of the species. Therefore, the complete mitogenome of O. aries was sequenced and annotated. In order to characterize the mitogenomes of 3 Chinese sheep breeds (Altay sheep [AL], Shandong large-tailed sheep [SD], and small-tailed Hulun Buir sheep [sHL]), 19 sets of primers were employed to amplify contiguous, overlapping segments of the complete mitochondrial DNA (mtDNA) sequence of each breed. The sizes of the complete mitochondrial genomes of the sHL, AL, and SD breeds were 16,617 bp, 16,613 bp, and 16,613 bp, respectively. The mitochondrial genomes were deposited in the GenBank database with accession numbers KP702285 (AL sheep), KP981378 (SD sheep), and KP981380 (sHL sheep) respectively. The organization of the 3 analyzed sheep mitochondrial genomes was similar, with each consisting of 22 tRNA genes, 2 rRNA genes (12S rRNA and 16S rRNA), 13 protein-coding genes, and 1 control region (D-loop). The NADH dehydrogenase subunit 6 (ND6) and 8 tRNA genes were encoded on the light strand, whereas the rest of the mitochondrial genes were encoded on the heavy strand. The nucleotide skewness of the coding strands of the 3 analyzed mitogenomes was biased toward A and T. We constructed a phylogenetic tree using the complete mitogenomes of each type of sheep to allow us to understand the genetic relationships between Chinese breeds of O. aries and those developed and utilized in other countries. Our findings provide important information regarding the O. aries mitogenome and the evolutionary history of O. aries inside and outside China. In addition, our results provide a foundation for further exploration of the taxonomic status of O. aries.
