Acoustic Change Responses to Amplitude Modulation: A Novel Method to Quantify Cortical Temporal Processing and Hemispheric Asymmetry

open access: yesFrontiers in Neuroscience, 2015
Objective: Sound modulation is a critical temporal cue for the perception of speech and environmental sounds. To examine auditory cortical responses to sound modulation, we developed an acoustic change stimulus involving amplitude modulation (AM) of ...

Quantum Dots (QD-Dye Conjugate) are Ideal Candidates for FRET Investigations Using TIRMicroscopy [PDF]

open access: yesEngineering and Technology Journal, 2014
Total Internal Reflection Microscopy has been employed to investigate Förster resonance energy transfer FRET for QD-dye conjugate system. QDs based donor systems are ideal for FRET for many reasons, one of them is that their broad excitation cross ...

Stability of quasi-two-dimensional Bose-Einstein condensates with dominant dipole-dipole interactions

open access: yes, 2006
We consider quasi-two-dimensional atomic/molecular Bose-Einstein condensates with both contact and dipole-dipole interactions. It is shown that, as a consequence of the dimensional reduction, and within mean-field theory, the condensates do not develop ...

Investigation of Wideband Substrate-Integrated Vertically-Polarized Electric Dipole Antenna and Arrays for mm-Wave 5G Mobile Devices

open access: yesIEEE Access, 2018
In this work, a mm-Wave vertically-polarized electric dipole array solution for 5G wireless devices is presented. The dipole is fabricated using vias in a standard PCB process to fit at the phone or tablet edges featuring wideband operation with broad ...

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

open access: yesAdvanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Dipole-dipole interaction between orthogonal dipole moments in time-dependent geometries

open access: yes, 2007
In two nearby atoms, the dipole-dipole interaction can couple transitions with orthogonal dipole moments. This orthogonal coupling accounts for a number of interesting effects, but strongly depends on the geometry of the setup.

Ab Initio Study on 3D Anisotropic Ferroelectric Switching Mechanism and Coercive Field in HfO2 and ZrO2

open access: yesAdvanced Functional Materials, EarlyView.
This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...
