Solid-state-biased coherent detection of ultra-broadband terahertz pulses [PDF]

open access: yes, 2017
Significant progress in nonlinear and ultrafast optics has recently opened new and exciting opportunities for terahertz (THz) science and technology, which require the development of reliable THz sources, detectors, and supporting devices.

Subclinical Optic Nerve Involvement in Radiologically Isolated Syndrome: Multimodal Detection and Diagnostic Impact

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We aimed to determine the frequency of subclinical optic nerve (ON) lesions using MRI, optical coherence tomography (OCT), and visual evoked potentials (VEP) in radiologically isolated syndrome (RIS), and to assess their diagnostic and prognostic significance.

Brightening self-trapped exciton emission in 2D metal-organic chalcogenolates via argentophilicity-mediated anisotropic compression

open access: yesNature Communications
An emerging class of two-dimensional semiconductor materials, metal-organic chalcogenolates (MOCs), have garnered significant attention due to the strong excitonic effects arising from their intrinsic soft, hybrid multiquantum-well structures.

Quantum field theory for coherent photons: isomorphism between Stokes parameters and spin expectation values

open access: yesFrontiers in Physics
Stokes parameters (S) on the Poincaré sphere are very useful values to describe the polarisation state of photons. However, the fundamental principle on the nature of polarisation is not completely understood, yet, because we have no concrete consensus ...

Non-Coherent Code Acquisition in the Multiple Transmit/Multiple Receive Antenna Aided Single- and Multi-Carrier DS-CDMA Downlink [PDF]

open access: yes, 2007
We analyse the characteristics of the Non-Coherent (NC) Multiple Transmit/Multiple Receive (MTMR) antenna aided Multi-Carrier (MC) DS-CDMA downlink employing a serial search based acquisition scheme, when communicating over spatially uncorrelated ...

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive motor neuron degeneration. Fused in sarcoma (FUS)‐associated juvenile ALS (jALS) represents a distinct and aggressive subgroup with rapid deterioration and poor prognosis.

Refinements To Longitudinal, Single Bunch, [PDF]

open access: yes, 2007
For the case of a bunched beam confined to a quadratic potential well, we demonstrate the necessity for considering modecoupling to correctly obtain the threshold current for the d.c. instability.

Human Pegivirus Encephalitis With Brain Detection and Response to Sofosbuvir Ledipasvir

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Human pegivirus (HPgV‐1) has been associated with severe encephalomyelitis in immunocompromised patients. Its neurological spectrum remains poorly defined. We report a slowly progressive encephalitis in a person living with well‐controlled HIV, characterized by white matter abnormalities and inflammatory cerebrospinal fluid (CSF). HPgV RNA was

Coherent two photon excitation within an extended cloud of Rubidium 85 for the purposes of atomic interferometry and cooling [PDF]

open access: yes, 2011
Cold atom samples, at temperatures of the order 100 µK, are useful for a wide reaching array of new and exciting technological and scientific endeavours. Atoms are conventionally cooled by Doppler cooling, which relies on the continuous absorption and re-
