Low pollinator visitation in harsh environments may lead to pollen limitation which can threaten population persistence. Consequently, avoidance of pollen limitation is expected in outcrossing species subjected to habitually low pollinator service. The elevational decline in visitation rates on many high mountains provides an outstanding opportunity for addressing this question. According to a ...
BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterized by chronic airflow limitation. The prevalence of airflow limitation in Japan is 10.9% (16.4% of males and 5.0% of females). Cigarette smoking is well known as a major cause of COPD. However, few epidemiological studies have evaluated the effects of cigarette smoking on pulmonary function in healthy subjects. METHODS Subj...
Current in vivo methods for imaging the visual cortex lack the ability to map response properties at the level of single cells. A new technique using two-photon imaging of calcium signals has now overcome this limitation.
A recently proposed method in deep learning groups multiple neurons to capsules such that each capsule represents an object or part of object. Routing algorithms route the output from lower-level layers upper-level layers. In this paper, we prove state-of-the-art routing procedures decrease expressivity networks. More precisely, it is shown EM-routing and routing-by-agreement prevent networks d...

By increasing the penetration level of the inverter-based distributed generations (IBDGs) in power system, their fault ride through capability has become one of the essential issues of the new grid codes. This paper proposes a novel method to limit inverter fault currents which are used in DGs. To achieve FRT, interface-inverter operates as a controlled voltage source during normal operation as...
the jointstock company as one of the most important commercial companies has advantages that distinguishs it from other ones. this paper wants to survey those in according to the current regulations and the new bylaw of trade act. it can be said that the require measure for the number of members and quantity of asset, portion of asset to stock, limitation of members liability to the nominal val...
In modern railway electric infrastructure design there are two major concerns that should be considered as touch voltage and stray current. The first problem is step which endangers human safety even to deathly situations. Second current leads corrosion of metallic infrastructure. Since has higher priority early on systems grounded the rail earth but this caused problem. Thus these problems han...
Abstract The debate on abortion has not yet found a clear solution. In fact, there is still discussion about what the limits of this procedure should be. This uncertainty related to lack definition human life: when can product conception be defined as being with full medical-legal rights? Based answer question, various world governments have drafted more or less restrictive laws regulating abor...
