Background Several face detection and recogni tion methods have been proposed in the past decades that have excellent *** conventional face recognition pipeline comprises the following:(1)face detection,(2)face alignment,(3)feature extraction,and(4)similarity,which are independent of each *** separate facial analysis stages lead to redundant model calculations,and are difficult for use in end-to-end *** In this paper,we propose a novel end-to-end trainable convolutional network framework for face detection and recognition,in which a geometric transformation matrix is directly learned to align the faces rather than predicting the facial *** the training stage,our single CNN model is supervised only by face bounding boxes and personal identities,which are publicly available from WIDER FACE and CASIA-WebFace *** model is tested on Face Detection Dataset and Benchmark(FDDB)and Labeled Face in the Wild(LFW)*** The results show 89.24%recall for face detection tasks and 98.63%accura cy for face recognition tasks.

As a carbon-storage compound and osmoprotectant in brown algae,mannitol is synthesized and then accumulated at high levels in Saccharina japonica(Sja);however,the underlying control mechanisms have not been *** analysis of genomic and transcriptomic data from Sja shows that mannitol metabolism is a cyclic pathway composed of four distinct steps.A mannitol-1-phosphate dehydrogenase(M1 PDH2)and two mannitol-1-phosphatases(M1 Pase1 and MIPase2)work together or in combination to exhibit full enzymatic *** on comprehensive transcriptomic data from different tissues,generations,and sexes as well as under different stress conditions,coupled with droplet digital PCR(dd PCR)and proteomic confirmation,we suggest that Sja M1 Pase1 plays a major role in mannitol biosynthesis and that the basic mannitol anabolism and the carbohydrate pool dynamics are responsible for carbon storage and anti-stress *** proteomic data indicate that mannitol metabolism remains constant during diurnal cycle in *** addition,we discover that mannitol-metabolism-associated(MMA)genes show differential expression between the multicellular filamentous(gametophyte)and large parenchymal thallus(sporophyte)generations and respond differentially to environmental stresses,such as hyposaline and hyperthermia *** results indicate that the ecophysiological significance of such differentially expressed genes may be attributable to the evolution of heteromorphic generations(filamentous and thallus)and environmental adaptation of Laminariales.

端部条件和展弦比是风洞试验节段模型设计的2个重要因素。为了研究端部条件和展弦比对节段模型气动力特征的影响,开展了不同端部条件和不同展弦比的宽高比5∶1矩形断面刚性节段模型静态测压风洞试验。研究结果表明:(1)端部条件和展弦比共同影响着节段模型上流场展向分布。(2)当模型长度大于2倍端部影响区间的长度时,模型上气动力在展向呈现等腰梯形分布;当模型长度小于2倍端部影响区间的长度时,模型上气动力在展向呈现等腰三角形分布。节段模型设计时应重视模型展弦比,合适的展弦比能获得更可靠的结果。
