Video editing is a high-required job, for it requires skilled artists or workers equipped with plentiful physical strength and multidisciplinary knowledge, such as cinematography, aesthetics. Thus gradually, more and more researches focus on proposing semi-automatical and even fully automatical solutions to reduce workloads. Since those conventional methods are usually designed to follow some simple guidelines, they lack flexibility and capability to learn complex ones. Fortunately, the advances of computer vision and machine learning make up the shortages of traditional approaches and make AI editing feasible. There is no survey to conclude those emerging researches yet. This paper summaries the development history of automatic video editing, and especially the applications of AI in partial and full workflows. We emphasizes video editing and discuss related works from multiple aspects: modality, type of input videos, methology, optimization, dataset, and evaluation metric. Besides, we also summarize the progresses in image editing domain, i.e., style transferring, retargeting, and colorization, and seek for the possibility to transfer those techniques to video domain. Finally, we give a brief conclusion about this survey and explore some open problems.

Abstract Focusing on seven major agricultural commodities with a long history of trade, this study employs data-driven analytics to decipher patterns of trade, namely using supervised machine learning (ML), as well as neural networks. The supervised ML and neural network techniques are trained on data until 2010 and 2014, respectively. Results show the high relevance of ML models to forecasting trade patterns in near- and long-term relative to traditional approaches, which are often subjective assessments or time-series projections. While supervised ML techniques quantified key economic factors underlying agricultural trade flows, neural network approaches provide better fits over the long term.

Thinking about security as a feminist international lawyer is necessarily complex and invites multiple layers of inquiry. Gender analysis commences with seeing the gendered consequences of security discourse and practice. That is, understanding women’s different experiences of insecurity in conflict, peace, and post-conflict spaces as well as different women’s experiences of those same spaces. Simultaneously, gender analysis questions the prevalence of military masculinities, the dynamics of hegemonic masculinity in the perpetuation of insecurity, and the continuum of gendered insecurity from the local to the international. Gender is thus an important conceptual and analytical tool for understanding traditional (state-centric) forms of international security, including collective security, the law of armed conflict, and post-conflict structures. However, feminist understandings of international security extend beyond traditional approaches to security, engaging everyday insecurity as a means to understand gendered insecurities from the local to the international, while centering the relationship between law and violence, challenging military masculinities, identifying the perpetuation of power and intersection of gender with race and colonialism, and asserting the value of knowledge production from transnational feminist networks. Contemporary feminist approaches have placed significant emphasis on the hypervisibility of conflict-related sexual violence and women’s access to political participation, however contemporary cutting-edge contributions call for deeper engagement with issues, including the recognition of intersectional, critical race, and transnational feminist interventions, the role of technology in international security, the need for a feminist, queer-antiracist politics within international security discourse, and the gendered and embodied reality of disability as a consequence of security threats. Much of the international legal scholarship, and the wider field of international relations where many of the pivotal texts emerge, centers the women, peace, and security agenda developed by the United Nations Security Council that was drafted after the shift toward human security in the 1990s. Yet this ignores the complex theorizations of gender from non-mainstream feminist contexts and risks the reproduction of modes of agents and victims that are aligned with the history of international law’s civilizing mission. International security, when viewed from a gender lens, thus offers the scholar a series of mechanisms for understanding the deep structures of international law while simultaneously challenging the mainstream production of gender as shorthand for women. The article includes a section on health that reflects the fact that it was prepared during the COVID-19 pandemic and the extended attention to the gendered elements of health insecurity that emerged at this time.

 Objective: Indian Traditional Medicine, the foundation of age-old practice of medicine in the world, has played an essential role in human health care service and welfare from its inception. Likewise, all traditional medicines are of its own regional effects and dominant in the West Asian nations; India, Pakistan, Tibet, and so forth, East Asian nations; China, Korea, Japan, Vietnam, and so forth, Africa, South and Central America. This article is an attempt to illuminate Indian traditional medical service and its importance, based on recent methodical reviews.Methods: Web search engines for example; Google, Science Direct and Google Scholar were employed for reviews as well as for meta-analysis.Results: There is a long running debate between individuals, who utilize Indian Traditional Medicines for different ailments and disorders, and the individuals who depend on the present day; modern medicine for cure. The civil argument between modern medicine and traditional medicines comes down to a basic truth; each person, regardless of education or sickness, ought to be educated about the actualities concerning their illness and the associated side effects of medicines. Therapeutic knowledge of Indian traditional medicine has propelled various traditional approaches with similar or different theories and methodologies, which are of regional significance.Conclusion: To extend research exercises on Indian Traditional Medicine, in near future, and to explore the phytochemicals; the current review will help the investigators involved in traditional medicinal pursuit.

This chapter discusses Milnor's conjecture on monotonicity of entropy and gives a short exposition of the ideas used in its proof. It discusses the history of this conjecture, gives an outline of the proof in the general case, and describes the state of the art in the subject. The proof makes use of an important result by Kozlovski, Shen, and van Strien on the density of hyperbolicity in the space of real polynomial maps, which is a far-reaching generalization of the Thurston Rigidity Theorem. (In the quadratic case, density of hyperbolicity had been proved in studies done by M. Lyubich and J. Graczyk and G. Swiatek.) The chapter concludes with a list of open problems.

AbstractA group K is said to be a B-group if every permutation group containing K as a regular subgroup is either imprimitive or 2-transitive. In the second edition of his influential textbook on finite groups, Burnside published a proof that cyclic groups of composite prime-power degree are B-groups. Ten years later, in 1921, he published a proof that every abelian group of composite degree is a B-group. Both proofs are character-theoretic and both have serious flaws. Indeed, the second result is false. In this paper we explain these flaws and prove that every cyclic group of composite order is a B-group, using only Burnside’s character-theoretic methods. We also survey the related literature, prove some new results on B-groups of prime-power order, state two related open problems and present some new computational data.

The Cichlid Speciation Project (CSP) is an ALife simulation system for investigating open problems in the speciation of African cichlid fish. The CSP can be used to perform a wide range of experiments that show that speciation is a natural consequence of certain biological systems. A visualization system capable of extracting the history of speciation from low-level trace data and creating a phylogenetic tree has been implemented. Unlike previous approaches, this visualization system presents a concrete trace of speciation, rather than a summary of low-level information from which the viewer can make subjective decisions on how speciation progressed. The phylogenetic trees are a more objective visualization of speciation, and enable automated collection and summarization of the results of experiments. The visualization system is used to create a phylogenetic tree from an experiment that models sympatric speciation.
