Linear systems over vector spaces and feedback morphisms form an additive category taking into account the parallel gathering of linear systems. This has a minimal exact structure thus notion simple as those have no subsystems apart from zero themselves. The so-called single-input are proven to be exactly in reachable spaces. is also semisimple objects because every system decomposed finite Hen...

Background Immunotherapy with T cells or bispecific T cell engagers is one promising approach to improve outcomes for patients with CD19-positive hematological malignancies. We had previously shown that T cells expressing bispecific T cell engagers that recognize CD19 and CD3 (CD19-ENG T cells) are activated in an antigen dependent manner, recruit resident T cells to tumors, and have anti-tumor...

many epidemiological studies have found that people living in environments with more green space report better physical and mental health than those with less green space. however, the association between visits to green space and mental health has seldom been studied. the environment surrounding residences and its recreational and commuting opportunities are believed to affect human health and...

'Space and place are central to the strategies and meaning of protest’ (p. xi) reads the opening sentence of Katrina Navickas's latest study, Protest and the Politics of Space and Place 1789–1848. Written, in part, as a response to the 'spatial turn' in History, Navickas makes a cogent and persuasive argument for attending to the importance of the particularities of 'place' rather than the abst...

The urban open public spaces are the areas where people tend to gather together, which may lead great crowd-gathering risk. This paper proposes a new method assess rank and spatial distribution of risk in large area. Firstly, crowd density estimation based on Tencent user (TUD) data is built for different times spaces. Then, reasonable threshold delimited detect critical situations find out key...
