Aiming at the hybrid flow-shop （HFS） scheduling that is a complex NP-hard combinatorial problem with wide engineering background, an effective algorithm based on differential evolution （DE） is proposed. By using a special encoding scheme and combining DE based evolutionary search and local search, the exploration and exploitation abilities are enhanced and well balanced for solving the HFS problems. Simulation results based on some typical problems and comparisons with some existing genetic algorithms demonstrate the proposed algorithm is effective, efficient and robust for solving the HFS problems.

Many dormitories have a high population density,and occupants exposed to volatile organic compounds(VOCs)could suffer severe physical and mental issues,so it is important to ensure good indoor air quality(IAQ).Currently,indoor VOC analysis using only chemical concentration cannot accurately reflect the effect of odor on human ***,the sensory evaluation of indoor odor acts as a supplementary method for an IAQ ***,we measured indoor VOC concentrations in 10 dormitories under occupied and unoccupied *** contribution of building materials and human-related emissions was *** odor activity value(OAV)was calculated using the VOC concentration and odorant *** addition,recruited sensory odor panel members assessed the odor intensity of each dormitory and the correlation between odor intensity and chemical measurements was *** indoor total VOC(TVOC)concentration under occupied conditions ranged from 242.2 to 1063.1μg/m^(3),with a mean value of 454.1μg/m^(3).The TVOC concentration under unoccupied conditions varied from 97.2 to 1055.2μg/m^(3),with a mean value of 342.2μg/m^(3).The TVOC concentration of 90% of the dormitories under the two conditions met the national IAQ *** average of 53.6% indoor TVOC emissions are related to building materials,the outdoor-related TVOC concentration accounts for 15.7%,and the average human-related TVOC emissions are 1519.4μg/(h·person),which accounts for 30.7%.Compared to TVOC concentration,odor intensity-OAV(OAV_(sum),OAV_(max))could better characterize subjective and objective ***,the goodness-of-fit is not ***–Fencher's law has limitations in characterizing the correlation between odor intensity and OAV when applied to the indoor air mixture,based on this small-scale study.

Low-resolution face images can be found in many practical applications. For example, faces captured from surveillance videos are typically in small sizes. Existing face recognition deep networks, trained on high-resolution images, perform poorly in recognizing low-resolution faces. In this work, an improved multi-branch network is proposed by combining ResNet and feature super-resolution modules. ResNet is for recognizing high-resolution facial images and extracting features from both high-and low-resolution *** super-resolution modules are inserted before the classifier of ResNet for low-resolution facial images. They are used to increase feature resolution. The proposed method is effective and simple. Experimental results show that the recognition accuracy for high-resolution face images is high, and the recognition accuracy for low-resolution face images is improved.

Objective To investigate the association of ghrelin gene polymorphisms with metabolic syndrome in Han Nationality Chinese. Methods A total of 240 patients with metabolic syndrome and 427 adults aged above forty years were recruited. Genotypes were determined by polymerase chain reaction and restriction fragment length polymorphism analysis. Results The allelic frequency of the Leu72Met polymorphism was 17.3% in the patient group and 11.9% in the control group （x^2=7.36, P=0.007）. Metabolic syndrome was more prevalent among carriers of the Met72 variant （43.8 vs 33.1%, age- and sex-adjusted odds ratio=1.57, P=0.01）. No Arg51Gln variants were found in our study subjects. Conclusion Rather than being associated with its individual components, Leu72Met polymorphism is associated with metabolic syndrome in the Han Nationality Chinese. Arg51Gln polymorphism is rare in the Han Nationality Chinese.
