Learning comprehensive spatiotemporal features is crucial for human action recognition. Existing methods tend to model the spatiotemporal feature blocks in an integrate-separate-integrate form, such as appearance-and-relation network(ARTNet) and spatiotemporal and motion network(STM). However, with blocks stacking up, the rear part of the network has poor interpretability. To avoid this problem, we propose a novel architecture called spatial temporal relation network(STRNet), which can learn explicit information of appearance, motion and especially the temporal relation information. Specifically, our STRNet is constructed by three branches,which separates the features into 1) appearance pathway, to obtain spatial semantics, 2) motion pathway, to reinforce the spatiotemporal feature representation, and 3) relation pathway, to focus on capturing temporal relation details of successive frames and to explore long-term representation dependency. In addition, our STRNet does not just simply merge the multi-branch information, but we apply a flexible and effective strategy to fuse the complementary information from multiple pathways. We evaluate our network on four major action recognition benchmarks: Kinetics-400, UCF-101, HMDB-51, and Something-Something v1, demonstrating that the performance of our STRNet achieves the state-of-the-art result on the UCF-101 and HMDB-51 datasets, as well as a comparable accuracy with the state-of-the-art method on Something-Something v1 and Kinetics-400.

The population density of the white-tailed sea eagle Haliaeetus albicilla is very low in many countries. In last twenty years, the sea eagle population in South Bohemia was restored by strict protection subsidized by reintroduction, The active help consisted of feeding during winter and building of artificial nests. A new sea eagle breeding population arose in the Treboǎ basin area in the early 1980＇ s. Until this time sea eagles had used former breeding places only for wintering, probably coming from the Baltic. The South Bohemian sea eagle population is very unique： it exists in a densely man-occupied landscape, mainly in areas with very intensive carp breeding in artificial fishponds and was partly artficially （help to wintering birds and reintroduction of some individuals） restored. The experience from South Bohemia may have importance for populations of the sea eagle in other areas of its occurence, primarily in the continental conditions [ Current Zoology 55 （5）： 315 - 318, 2009].

It is considerably difficult to assess and evaluate the Simla Conference (1913--1914) and itsoutcome in all theoretical and practical aspects, and considering the permanent unavailability andrelative inaccessibility of some sources related directly or indirectly to the course and conclusions ofSimta proceedings, it is also impossible, as a matter of fact. However, this should not prevent usfrom trying -- with the given means -- to analyze at least partially some of the most important

Pharmacopoeial standards for crude drugs are established based on analysis of authenticated specimens which should be representative of the quality of material traditionally specified in systems of traditional medicine from species' geographical origin. This reflects the ‘geo-authentic'material that corresponds to traditional ecological and medical knowledge. In cases where specimens are obtained from cultivation outside of the species origin, this ‘authenticated' material will not be ‘geo-authentic'.There is a growing trend for the protection of ‘geographical indication'(GI) botanicals in the context of intellectual property rights. GI botanicals are named after a geographical area, indicating production within a particular area, quality and characteristics dependent on natural,historical and cultural factors. However, with the globalization of systems of traditional medicine such as Ayurvedic medicine and traditional Chinese medicine, Asian species are being introduced to cultivation outside of their geographical origins particularly in the EU and *** contrast to the Chinese concept of ‘daodi' and European concepts of ‘provenance' or ‘terroir' is the competing trend for ‘locally grown'herbs, i.e. cultivated closer to where they will be used. Reasons include concerns about quality control, contamination from polluted air, soil and water in some source countries, climate change, supply chain security and traceability, costs of production and price *** review looks at selected agronomic experiments aiming to discern differences between geo-authentic medicinal herbs vs. introduced crops and whether the global market cares to make a distinction or pay a price premium for articles with designations of geographical origin of specified quality.

In this essay, I take the recent publication of several texts examining the historical and contemporary phenomena of Sinophobia, Orientalism, and Sinologism as an opening for theorizing underlying and related issues including pervasive anti-China biases in Western journalism and China＇s position therein. In addition to illustrating how the concepts of Orientalism arise from Western historical and epistemological foundations, I theorize what I call a ＂new yellow journalism＂ that has grown in tandem with ＂China＇s rise＂ and the threat this indicates to many Western observers, and how this threat and others like it have been met in the age of ＂new imperialism.＂ I compare this new phenomenon with its historical antecedents, ＂yellow journalism＂ and America＇s emergence as a imperialism power with the Spanish-American War （1898）, and note several key insights offered by recent critical analyses of that period, which together suggest a confluence of different players, including policymakers, new media business models, and what I describe as a type of public ＂corporatism＂ in which citizens, particularly Americans, function effectively as shareholders in maintaining hegemonic if not imperialist power.

With the complementarity of the nucleonic three-body force,we present the saturation points of symmetric nuclear matter with different interactions adopted within the Brueckner-Hartree-Fock scheme,and a more accurate empirical parameterization function for the equation of state of symmetric nuclear matter and pure neutron *** the basis of this fit formula,the symmetry energy and its derivatives are investigated,and ultimately the higher-order coefficient of the isobaric incompressibility for isospin asymmetric nuclear matter is predicted.
