Investigation and Analysis of Present Situation and Educational Countermeasures and Cultural Needs of Farmers

The samples, from 21 provinces, municipalities directly under the central government, 107 villages, 30 towns, are altogether 3,577. The survey found, the cultural demand of farmers is generally healthy and positive. What they need most are cultural knowledge of computer technology, disease prevention knowledge, legal knowledge to deal with disputes, migrant workers rights of women and children protection law, recreational activities are singing and dancing, favorite sports activities the first three are the small ball (table tennis badminton), major sports (basketball and volleyball football) and the short or long runs. And there are some differences in age, gender, and cultural degree of life state between these demands. Investigation and analysis reflect that, some activities already undertaken can’t meet the need, and some farmers on the surface needn’t culture, but actually reflect the lag of cultural spiritual pursuit. By contrast with sports, entertainment is more short of physical activity. Farmers’ favorite access to cultural knowledge is face-to-face teaching. However, the “information price ratio” of “three rural areas “ activities are lower than others. According to the problems, we put forward some strategic suggestions on software and hardware

Dynamic Global Memory for Document-level Argument Extraction

Extracting informative arguments of events from news articles is a challenging problem in information extraction, which requires a global contextual understanding of each document. While recent work on document-level extraction has gone beyond single-sentence and increased the cross-sentence inference capability of end-to-end models, they are still restricted by certain input sequence length constraints and usually ignore the global context between events. To tackle this issue, we introduce a new global neural generation-based framework for document-level event argument extraction by constructing a document memory store to record the contextual event information and leveraging it to implicitly and explicitly help with decoding of arguments for later events. Empirical results show that our framework outperforms prior methods substantially and it is more robust to adversarially annotated examples with our constrained decoding design.

Feasibility and principle analyses of morphing airfoil used to control flight attitude

Morphing airfoil technology can enable an aircraft to adapt its shape to enhance mission performance and replace the traditional flap, ailerons, elevator and rudders to optimize flight attitude control efficiency. A set of optimal airfoil shapes are obtained aimed to minimize the aerodynamic drag character by optimizing morphing configurations at different under the two-dimensional steady-flow simulation. The traditional airfoil and morphing airfoil at different are compared. It is proved that morphing wing can be used instead of a traditional wing. Couples of traditional control surface and morphing airfoil are chosen to simulate and analyze the aerodynamic difference. The flow mechanism is described on the basis of aerodynamic simulations performed by CFX. It is demonstrated why the morphing wing can provide the same with a small

Intermediate cell states in epithelial-to-mesenchymal transition

The transition of epithelial cells into a mesenchymal state (epithelial-to-mesenchymal transition or EMT) is a highly dynamic process implicated in various biological processes. During EMT, cells do not necessarily exist in ‘pure’ epithelial or mesenchymal states. There are cells with mixed (or hybrid) features of the two, which are termed as the intermediate cell states (ICSs). While the exact functions of ICS remain elusive, together with EMT it appears to play important roles in embryogenesis, tissue development, and pathological processes such as cancer metastasis. Recent single cell experiments and advanced mathematical modeling have improved our capability in identifying ICS and provided a better understanding of ICS in development and disease. Here, we review the recent findings related to the ICS in/or EMT and highlight the challenges in the identification and functional characterization of ICS

Hospital psychosocial interventions for patients with brain functional impairment: A retrospective cohort study

ABSTRACT: Psychosocial interventions could improve health and care outcomes, however, little is known about their use for patients with complex needs in the acute hospital care setting. This study aimed to evaluate factors associated with psychosocial intervention use when treating patients with brain functional impairment during their hospital care. The all-inclusive New South Wales (NSW) Admitted Patient Data were employed to identify patients with neurodevelopment disorders, brain degenerative disorders, or traumatic brain injuries admitted to NSW public hospitals for acute care from July 2001 to June 2014. We considered receipt of psychosocial interventions as the primary outcome, and used mixed effect logistic models to quantify factors in relation to outcome. Of important note, psychosocial intervention use was more common in principal hospitals, and amongst those receiving intensive care or having comorbid mental disorders in the study populations. Approximate 70.8% of patients with traumatic brain injuries did not receive psychosocial interventions, despite attempts to target those in need and an overall increasing trend in adoption. Continuing efforts are warranted to improve service delivery and uptake. KEY WORDS: brain degenerative disorders, hospital psychiatry, neurodevelopment disorders, psychosocial intervention, traumatic brain injuries

Feasibility and effect of para-right bundle branch pacing in patients with atrial fibrillation and complete atrioventricular block

Background: Chronic right ventricular apex (RVA) pacing can induce negative clinical effects. The aim of the present study was to compare RVA pacing with para-right bundle branch (para-RBB) pacing in terms of electrocardiogram (ECG) and echocardiographic (ECHO) features. Methods: Forty-one consecutive persistent atrial fibrillation patients with an indication for permanent pacing treatment due to complete atrioventricular block were randomly assigned to receive a screw-in lead either in the RVA (n = 22) or at the para-RBB (n = 19). Para-RBB pacing leads were located according to the RBB potential recorded by electrophysiology catheter. ECG was recorded before and after implantation. All patients underwent the pacemaker pro­gramming at 1 day, 6 months, 12 months and 24 months after implantation. ECHO examina­tion was performed during follow-up at 6, 12 and 24 months after implantation to assess the heart function and synchronism. Results: There was no significant difference in pacing lead parameters between para-RBB pacing group and RVA pacing group. Compared with RVA pacing group, the para-RBB pacing group obtained a narrower QRS complex, more synchronic ventricular systole, and less nega­tive effect on heart function (p < 0.05). Conclusions: Para-RBB pacing has potential clinical benefits and may be a physiological pacing site.

(S)-Ethyl 1,2,3,9-tetra­hydro­pyrrolo[2,1-b]quinazoline-1-carboxyl­ate

The title chiral compound, C14H16N2O2, was prepared by esterification of (S)-1,2,3,9-tetra­hydro­pyrrolo[2,1-b]quinazol­in-1-carboxylic acid in the presence of HCl/EtOH. In the mol­ecule, the quinazoline ring is non-planar and exhibits a distorted half-chair conformation, while the five-membered ring shows a typical envelope conformation.
