Developmental instability is often assessed using deviations from perfect bilateral symmetry. Here, we review the literature describing previous studies, suggest mechanisms that may account for both the generation and disruption of bilateral symmetry, and examine the influence of electromagnetic fields on the asymmetry of soybean leaves. Leaves from plants under high-voltage power lines generat...

In a previous work the eigenmodes of a muffin–tin structure limited with lateral electric walls were calculated using the mode matching technique. Now a modulated off axis beam is introduced and the beam induced fields, as well as the longitudinal coupling impedances are calculated. Furthermore, in order to get the fields in case of the open structure, the discrete set of modes in the field exp...

Neurons in the lateral intraparietal area (LIP) of the monkey represent salient stimuli. They respond to recently flashed stimuli that enter their receptive fields by virtue of saccades better than they respond to stable, behaviorally irrelevant stimuli brought into their receptive fields by saccades. They respond transiently to abrupt motion onsets, but have no directional selectivity. They re...

The sources of ipsilateral projections from the hippocampal formation, the presubiculum, area 29a-c, and parasubiculum to medial, orbital, and lateral prefrontal cortices were studied with retrograde tracers in 27 rhesus monkeys. Labeled neurons within the hippocampal formation (CA1, CA1', prosubiculum, and subiculum) were found rostrally, although some were noted throughout the entire rostroca...

In the course of performing electrical stimulation functional mapping (ESFM) in neurosurgery patients, we identified three subjects who experienced hearing suppression during stimulation of sites within the superior temporal gyrus (STG). One of these patients had long standing tinnitus that affected both ears. In all subjects, auditory event related potentials (ERPs) were recorded from chronica...

The process of identifying techniques for fostering creativity, and applying these theoretical constructs in real-world educational activities, is, by nature, multifaceted and not straightforward, pertaining to several fields such as cognitive theory and psychology. Furthermore, the quantification of the impact of different activities on creativity is a challenging and not yet thoroughly invest...

Manipulating spin polarization of electrons in nonmagnetic semiconductors by means of electric fields or optical fields is an essential theme of the conceptual nonmagnetic semiconductor-based spintronics. Here we experimentally demonstrate an electric method of detecting spin polarization in monolayer transition metal dichalcogenides (TMDs) generated by circularly polarized optical pumping. The...

This study presents an analysis of effectiveness of different designs of baffles, including the conventional, partial and oblique, in limiting the manoeuvre-induced transient as well as steady-state fluid slosh forces and moments in a partly-filled tank truck. The effect of an alternating arrangement of partial baffles is also explored. A three-dimensional computational fluid dynamics model of ...

Part (I) of this study presented field and laboratory experimental data on soil characteristics and hydraulic parameters that are related to water infiltration in rice paddy fields. Part (II) includes a series of numerical simulations that are based on the in situ data, which three-dimensional finite element computer model for simulating density dependent flow and transport (FEMWATER) produced ...

Lateral competition within a layer of neurons sharpens and localizes the response to an input stimulus. Here, we investigate a model for the activity dependent development of ocular dominance maps which allows to vary the degree of lateral competition. For weak competition, it resembles a correlation-based learning model and for strong competition, it becomes a self-organizing map. Thus, in the...
