Two questions in the research of animal personality—whether there is a correlation between a personality trait and individual reproductive success,and what is the genetic basis underlying a personality trait—remain unresolved.We addressed these two questions in three shrub-nesting birds,the Azure-winged Magpie(Cyanopica cyanus,AM),White-collared Blackbird(Turdus albocinctus,WB),and Brown-cheeked Laughingthrush(Trochalopteron henrici,BL).The personality type of an individual was first identified according to its response to a territorial intruder.Then,we compared the fleeing distance,breeding parameters,and differential expressed genes(DEGs) in the brain transcriptome between bold and shy breeders.In the three species,bold breeders exhibited more aggressiveness towards an intruder of their territory than did shy breeders.The reproductive success of bold breeders was significantly higher than that of shy breeders in AM but not in WB and BL.The three species shared one DEG,crabp1,which was up-regulated in bold relative to in shy individuals.By regulating the expression of corticotropin-releasing hormone,higher crabp1 gene expression can decrease cellular response to retinoic acid.Therefore,bold individuals are insensitive to external stresses and able to exhibit more aggressiveness to intruders than their shier counterparts.Aggressiveness is beneficial to bold individuals in AM but not in WB and BL because the former could evoke neighbors to make the same response of defending against intruders but the latter could not.Although a personality trait may have the same genetic basis across species,its correlation with reproductive success depends largely on the life history style of a species.

Dispersal is an individual life-history trait that can influence the ecological and evolutionary dynamics of both the source and recipient populations.Current studies of animal dispersal have paid little attention to how the responses of residents in a recipient population affect the social resettlement of dispersers into a new habitat.We addressed this question in the blue-breasted quail Synoicus chinensis by designing an outsider introduction experiment to simulate a scenario of interaction between residents and dispersers.In the experiment,we introduced an unfamiliar quail into a group of 3 differently ranked residents and then examined their behavioral responses to the arrival of the outsider.We found that all residents made negative responses by pecking at the outsider to maintain their pecking order,in which high-ranked residents displayed significantly greater intensity than those of lower ranks.This result highlighted that adverse behavioral responses of residents would prevent outsiders from obtaining hierarchical dominance in the recipient group.Moreover,the residents’sex ratio,their relative ages to the outsiders,and whether outsiders counter-pecked at the residents all influenced the probability of outsiders prevailing against the residents.Those outsiders that displayed counter-peck courage were more likely to gain higher dominance and hence resettle into the recipient group successfully.Our findings suggest that resident groups may impose a selection among dispersers via adverse behavioral responses.Therefore,social factors that can influence the resettlement step of dispersers in a new habitat should be accounted for in future studies of animal dispersal.

Predator–prey interaction has long been an interesting item in the research of animal behaviors.Given that live prey can damage their predators,predators must trade foraging efficiency for safety while hunting,but the extent of this trade-off is not yet clear.Tiger beetles display diversity in their diets and hunting strategies,and hence,they become an ideal system to address how self-security affects foraging efficiency.We addressed this question in captive adult tiger beetles Cicindela gemmata.By offering several types of arthropod and plant foods,we confirmed that C.gemmata is carnivorous.We found that C.gemmata hunt by either ambushing or chasing their prey,and that they switch between strategies based on differences in the number of prey,the prey status and encounter rate,and the number of predators.Ambushing success increased with the number of prey but decreased with prey encounter rate.Chasing success decreased as prey body size and encounter rate increased.Foraging Cicindela gemmata often gave up an attack when it was nonfatal.This active giving up of hunting may be a consequence of a trade-off between foraging efficiency and self-security.Therefore,it is an adaptive response to the risk of injury when hunting for larger live prey.

Data sharing and privacy securing present extensive opportunities and challenges in vehicular network.This paper introducestrust access authentication scheme’as a mechanism to achieve real-time monitoring and promote collaborative sharing for vehicles.Blockchain,which can provide secure authentication and protected privacy,is a crucial technology.However,traditional cloud computing performs poorly in supplying low-latency and fast-response services for moving vehicles.In this situation,edge computing enabled Blockchain network appeals to be a promising method,where moving vehicles can access storage or computing resource and get authenticated from Blockchain edge nodes directly.In this paper,a hierarchical architecture is proposed consist of vehicular network layer,Blockchain edge layer and Blockchain network layer.Through a authentication mechanism adopting digital signature algorithm,it achieves trusted authentication and ensures valid verification.Moreover,a caching scheme based on many-to-many matching is proposed to minimize average delivery delay of vehicles.Simulation results prove that the proposed caching scheme has a better performance than existing schemes based on central-ized model or edge caching strategy in terms of hit ratio and average delay.

Background:Great diversity exists in the parenting pattern of altricial birds,which has long been considered as an adaptive response to specific environmental conditions but not to their life-history style.Methods:We examined the egg-laying and nestling-raising pattern of the Grey-backed Shrike(Lanius tephronotus)that breeds only once a year on the Tibetan Plateau.We compared the dietary composition to that of its sympatric competitor,the Brown-cheeked Laughing Thrush(Trochalopteron henrici)that breeds twice a year.Results:Female Grey-backed Shrikes produced a fixed clutch size of five,with increasing egg size by their laying sequence.The last offspring in the brood is disadvantageous in the size hierarchy because it hatches later.However,they had the largest fledgling body mass.These findings indicate that Grey-backed Shrikes adopt the brood survival strategy in both the egg and nestling phases.Moreover,males and females exhibit no sexual division in providing parental care as they made an equal contribution to the total amount of food delivered to their brood.This parenting pattern of Grey-backed Shrikes,as well as their dietary items,differ significantly from those of the Brown-cheeked Laughing Thrush.Conclusions:We suggest that the differentiation in life-history style between sympatric competitors,rather than a behavioral response to specific environmental conditions,plays a decisive role in driving avian parenting strategy diversification.

One purpose of this study was to develop a paliperidone(PAL)tri-layer ascending release pushepull osmotic pump(TA-PPOP)tablet which could meet the needs of clinical applications.And another purpose was to investigate whether different coating materials influenced in vivo performance of TA-PPOP.The ascending release mechanism of this trilayer delivery system on theory was elaborated.TA-PPOP was prepared by means of coating with cellulose acetate(CA)or ethyl cellulose(EC).Several important influence factors such as different core tablet compositions and different coating solution ingredients involved in the formulation procedure were investigated.The optimization of formulation and process was conducted by comparing different in vitro release behaviors of PAL.In vitro dissolution studies indicated that both the two formulations of different coating materials were able to deliver PAL at an ascending release rate during the whole 24 h test.The in vivo pharmacokinetics study showed that both self-made PPOP tablets with different coating had a good in vitro-in vivo correlation(IVIVC)and were bioequivalent with the brand product,which demonstrated no significant influence of the coating materials on the in vivo release acceleration of TA-PPOP.

Liveness detection of occluded face based on dual-modality convolutional neural network

引用

The Journal of China Universities of Posts and Telecommunications 2021年第4期28卷 1-12页

作者： Ming Yue Li Wenmin Xu Siya gao lifang Zhang Hua Shao Sujie Yang Huifeng State Key Laboratory of Networking and Switching Technology Beijing University of Posts and TelecommunicationsBeijing 100876China State Grid Hebei Information and Telecommunication Branch Shijiazhuang 050013China

Facial recognition has become the most common identity authentication technologies. However, problems such as uneven light and occluded faces have increased the hardness of liveness detection. Nevertheless, there are a few pieces of research on face liveness detection under occlusion conditions. This paper designs a face recognition technique suitable for different degrees of facial occlusion, which employs the facial datasets of near-infrared(NIR) images and visible(VIS) light images to examine the single-modality detection accuracy rate(experimental control group) and the corresponding high-dimensional features through the residual network(ResNet). Based on the idea of data fusion, we propose two feature fusion methods. The two methods extract and fuse the data of one and two convolutional layers from two single-modality detectors respectively. The fusion of high-dimensional features apply a new ResNet to get the dual-modality detection accuracy. And then, a new ResNet is applied to test the accuracy of dual-modality detection. The experimental results show that the dual-modality face liveness detection model improves face live detection accuracy and robustness compared with the single-modality. The fusion of two-layer features from the single-modality detector can also improve face detection accuracy by utilizing the above-mentioned dual-modality detector, and it doesn’t increase the algorithm’s complexity.
