We show the point-spread function of a confocal microscope with an increased detection aperture. The increase in aperture is accomplished by coherent collection of the light from the specimen with two opposing objective lenses, i.e., type-B 4Pi confocal microscopy. We demonstrate experimentally its feasibility for detecting scattered or fluorescently emitted light. The 4Pi confocal point-spread...

In this article, the authors develop a definition of positive deviance, a foundational construct in positive organizational scholarship. They offer a normative definition of positive deviance: intentional behaviors that depart from the norms of a referent group in honorable ways. The authors contrast this normative perspective on deviance with statistical, supraconformity, and reactive perspect...

Abstract The largest recorded flood loss occurred in the study area 2013. This aims to examine resampling methods (i.e. cross-validation (CV), bootstrap, and random subsampling) improve performance of seven basic machine learning algorithms: Generalized Linear Model, Support Vector Machine, Random Forest (RF), Boosted Regression Tree, Multivariate Adaptive Splines, Mixture Discriminate Analysis...

When a vortex beam with a spiral phase structure passes through dynamic angular double slits (ADS), the interference pattern changes alternatively between destructive and constructive at the angular bisector of the ADS. This change is due to their phase difference. Based on this property, we experimentally demonstrate a simple method to precisely and efficiently determine the topological charge...

Flexoelectricity is an electromechanical effect coupling polarization to strain gradients. It fundamentally differs from piezoelectricity because of its size-dependence and symmetry. Flexoelectricity is generally perceived as a small effect noticeable only at the nanoscale. Since ferroelectric ceramics have a particularly high flexoelectric coefficient, however, it may play a significant role a...

The phenomenon of stochastic resonance has recently been found in many systems. Despite the pre-conception of a destructive role of noise, its constructive role has been recognised, in particular in ampli5cation of weak external signals, thereby facilitating signal detection and transduction in complex systems. Although the stochastic resonance has been reported for many systems in various 5eld...

Election control considers the problem of an adversary who attempts to tamper with a voting process, in order to either ensure that their favored candidate wins (constructive control) or another candidate loses (destructive control). As online social networks have become significant sources of information for potential voters, a new tool in an attacker’s arsenal is to effect control by harnessi...

Followership is a developing paradigm in organizational behavior which focusesmainly on followers. The goal of this study is to explore follower’s implicitfollowership theories (IFTs) which entail an analysis of follower’s views andperception about followership. For this purpose, based on a phenomenologicalapproach, semi-structured interviews with employees of large public and privateorganizati...
