heavy metal pollution plays an important role in global biodiversity decline. however, there is paucity of information concerning the effects of metals on amphibians. in the present study, investigations were made on the accumulation of heavy metals, copper (cu) and lead (pb) in water, sediment and tadpoles inhabiting the water bodies of barak valley, assam. tadpoles of six different anuran spe...

to identify arbuscular mycorrhiza fungi (amf) associated with crataegus pontica c. koch, 54 soil samples were collected from the rhizosphere of this plant in ilam province, western iran. isolation of mycorrhizal spores was conducted by wet sieving followed by centrifuge. amf were identified based on morphological characteristics of spores. in this study, 13 species of amf belonging to five gene...

We theoretically demonstrate that 100% valley-polarized transport in monolayers of MoS2 and other group-VI dichalcogenides can be obtained using off-resonant circularly polarized light. By tuning the intensity of the off-resonant light the intrinsic band gap in one valley is reduced, while it is enhanced in the other valley, enabling single valley quantum transport. As a consequence, we predict...

The ‘Uncanny Valley’ refers to a sense of unease and discomfort when people look at increasingly realistic virtual humans. Despite growing academic interest in the Uncanny Valley our understanding is limited and there has been little rigorous questioning to determine if the phenomenon actually exists. The Uncanny Valley questions widely held assumptions about the correlation between realism and...

AIM An analysis of general practice data for rural communities in close proximity to coal mining and coal-fired power generation in the Hunter Valley region of NSW was conducted to identify unusual patterns of illness. METHODS Bettering the Evaluation and Care of Health general practice consultation data from the Hunter Valley region for 1998-2010 were compared with data from all other rural ...

Exploring why stochastic gradient descent (SGD) based optimization methods train deep neural networks (DNNs) that generalize well has become an active area of research. Towards this end, we empirically study the dynamics of SGD when training over-parametrized DNNs. Specifically we study the DNN loss surface along the trajectory of SGD by interpolating the loss surface between parameters from co...

We study the spin- and valley-dependent energy band and transport property of silicene under a periodic potential, where both spin and valley degeneracies are lifted. It is found that the Dirac point, miniband, band gap, anisotropic velocity, and conductance strongly depend on the spin and valley indices. The extra Dirac points appear as the voltage potential increases, the critical values of w...

It can be creepy to notice that something human-looking is not real. But can sensitivity to this phenomenon, known as the uncanny valley, be predicted from superficially unrelated traits? Based on results from at least 489 participants, this study examines the relation between nine theoretically motivated trait indices and uncanny valley sensitivity, operationalized as increased eerie ratings a...

River valley segments are adjacent sections of streams and rivers that are relatively homogeneous in hydrology, limnology, channel morphology, riparian dynamics, and biological communities. River valley segments have been advocated as appropriate spatial units for assessing, monitoring, and managing rivers and streams for several reasons; however, methods for delineating these spatial units hav...
