Current status and innovation attempt of compiling textbooks of Chinese medicine in medical colleges in China

At present,there are two modes in the compilation of textbooks of traditional Chinese medicine,one is stuck in one's own way and the other is to copy Western medicine completely.The reason is that the textbooks of traditional Chinese medicine colleges and universities are reduced into a hodger with no purpose,or the other is to cater to Western medicine system and give up the academic system of traditional Chinese medicine and lose the essence of traditional Chinese medicine.Through the"diagnosis and treatment strategy"and"knowledge link"of the new Chinese medicine textbooks,the author tries to make a breakthrough in the compilation,and puts forward the compilation ideas of rectifying the position of Chinese medicine textbooks,starting from the learning thinking of Western medicine students,and reflecting the characteristics of Chinese medicine and modern research results.

Research on Uniform Array Beamforming Based on Support Vector Regression

An approach was proposed for optimizing beamforming that was based on Support Vector Regression (SVR). After studying the mathematical principal of the SVR algorithm and its primal cost function, the modified cost function was first applied to uniform array beamforming, and then the corresponding parameters of the beamforming were optimized. The framework of SVR uniform array beamforming was then established. Simulation results show that SVR beamforming can not only approximate the performance of conventional beamforming in the area without noise and with small data sets, but also improve the generalization ability and reduce the computation burden. Also, the side lobe level of both linear and circular arrays by the SVR algorithm is improved sharply through comparison with the conventional one. SVR beamforming is superior to the conventional method in both linear and circular arrays, under single source or double non-coherent sources.

Assessing the spread risk of COVID-19 associated with multi-mode transportation networks in China

The spatial spread of COVID-19 during early 2020 in China was primarily driven by outbound travelers leaving the epicenter,Wuhan,Hubei province.Existing studies focus on the influence of aggregated out-bound population flows originating from Wuhan;however,the impacts of different modes of transportation and the network structure of transportation systems on the early spread of COVID-19 in China are not well understood.Here,we assess the roles of the road,railway,and air transportation networks in driving the spatial spread of COVID-19 in China.We find that the short-range spread within Hubei province was dominated by ground traffic,notably,the railway transportation.In contrast,long-range spread to cities in other provinces was mediated by multiple factors,including a higher risk of case importation associated with air transportation and a larger outbreak size in hub cities located at the center of transportation networks.We further show that,although the dissemination of SARS-CoV-2 across countries and continents is determined by the worldwide air transportation network,the early geographic dispersal of COVID-19 within China is better predicted by the railway traffic.Given the recent emergence of multiple more transmissible variants of SARS-CoV-2,our findings can support a better assessment of the spread risk of those variants and improve future pandemic preparedness and responses.

The Strength of Structural Diversity in Online Social Networks

Understanding the way individuals are interconnected in social networks is of prime significance to predict their collective outcomes.Leveraging a large-scale dataset from a knowledge-sharing website,this paper presents an exploratory investigation of the way to depict structural diversity in directed networks and how it can be utilized to predict one’s online social reputation.To capture the structural diversity of an individual,we first consider the number of weakly and strongly connected components in one’s contact neighborhood and further take the coexposure network of social neighbors into consideration.We show empirical evidence that the structural diversity of an individual is able to provide valuable insights to predict personal online social reputation,and the inclusion of a coexposure network provides an additional ingredient to achieve that goal.After synthetically controlling several possible confounding factors through matching experiments,structural diversity still plays a nonnegligible role in the prediction of personal online social reputation.Our work constitutes one of the first attempts to empirically study structural diversity in directed networks and has practical implications for a range of domains,such as social influence and collective intelligence studies.

Minor Movies： On the Deterritorialising Power of Wong Kar-wai＇s Works

The article approaches Wong Kar-wai＇s cinematic work using the notion of ＂minor literature＂ as coined by Gilles Deleuze and F61ix Guattari. Minor literature--or, in other words, minor language signifies oppositional/resistant uses of a major/hegemonic language. It appropriates hegemonic language and deterritorialises it by re-signifying its original meanings. By transferring this concept from literature to cinema, we can describe Hong Kong cinema, which deterritorialises Hollywood cinema, as a minor cinema in relation to Hollywood. Following this interpretation, Wong Kar-wai＇s movies appear as a ＂minor language of a minor cinema＂ because they are significantly different from Hong Kong＇s mainstream action cinema. Consequently, Wong＇s movies possess a high level of deterritorialising power, which opens up new spaces of meaning and gives voice to positions usually oppressed by mainstream cinema. Finally, a close reading of Wong＇s movie Happy Together shows how ＂minor movies＂ challenge the mainstream＇s unison and give space to a resistant and transforming polyphony.

Heterogeneous influence of individuals’ behavior on mask efficacy in gathering environments

Wearing masks is an easy way to operate and popular measure for preventing epidemics.Although masks can slow down the spread of viruses,their efficacy in gathering environments involving heterogeneous person-to-person contacts remains unknown.Therefore,we aim to investigate the epidemic prevention effect of masks in different real-life gathering environments.This study uses four real interpersonal contact datasets to construct four empirical networks to represent four gathering environments.The transmission of COVID-19 is simulated using the Monte Carlo simulation method.The heterogeneity of individuals can cause mask efficacy in a specific gathering environment to be different from the baseline efficacy in general society.Furthermore,the heterogeneity of gathering environments causes the epidemic prevention effect of masks to differ.Wearing masks can greatly reduce the probability of clustered epidemics and the infection scale in primary schools,high schools,and hospitals.However,the use of masks alone in primary schools and hospitals cannot control outbreaks.In high schools with social distancing between classes and in workplaces where the interpersonal contact is relatively sparse,masks can meet the need for prevention.Given the heterogeneity of individual behavior,if individuals who are more active in terms of interpersonal contact are prioritized for mask-wearing,the epidemic prevention effect of masks can be improved.Finally,asymptomatic infection has varying effects on the prevention effect of masks in different environments.The effect can be weakened or eliminated by increasing the usage rate of masks in high schools and workplaces.However,the effect on primary schools and hospitals cannot be weakened.This study contributes to the accurate evaluation of mask efficacy in various gathering environments to provide scientific guidance for epidemic prevention.

Intellectual Humility and Owning One's Limitations

Intellectual humility is a worthwhile virtue. Whitcomb et al.(Philos Phenomenol Res 94(3):520, 2017) recently propose a novel account of intellectual humility. According to this account, intellectual humility consists of proper attentiveness to and owning o f one's intellectual limitations. We argue that this account is in accordance with empirical work on intellectual humility, but it has two problems. It leaves open the possibility that one can be both intellectually humble and arrogant and that it does not adequately explain the strangeness associated with self-attribution of intellectual humility. Subsequently, we explore an interesting connection between intellectual humility and ignorance. Our view is that intellectual humility can lead to ignorance in the internalist sense, but this is acceptable, in that intellectual humility also gives rise to valuable epistemic standings, such as understanding and wisdom.
