PRAXIS: a low background NIR spectrograph for fibre Bragg grating OH suppression

open access: yes, 2012
Fibre Bragg grating (FBG) OH suppression is capable of greatly reducing the bright sky background seen by near infrared spectrographs. By filtering out the airglow emission lines at high resolution before the light enters the spectrograph this technique ...

Emergence of Light‐Transforming Layered Hybrid Halide Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
The emerging class of light‐transforming layered halide perovskite materials is reviewed, outlining challenges for their development and perspectives toward application in the future. Abstract Layered hybrid halide perovskites (LHPs) have attracted considerable attention in optoelectronics.

Role of autoimmunity in the etiopathogenesis of Ross syndrome

open access: yesThe Pan-American Journal of Ophthalmology
Ross syndrome is a rare clinical entity that manifests classically with a triad of segmental anhidrosis, tonic pupil, and hyporeflexia. Here, we present a case of Ross syndrome in a university-going female in her early twenties with a history of ...

An overview of current approaches and future challenges in physiological monitoring [PDF]

open access: yes
Sufficient evidence exists from laboratory studies to suggest that physiological measures can be useful as an adjunct to behavioral and subjective measures of human performance and capabilities.

Acute tryptophan depletion attenuates conscious appraisal of social emotional signals in healthy female volunteers [PDF]

open access: yes, 2010
Rationale: Acute tryptophan depletion (ATD) decreases levels of central serotonin. ATD thus enables the cognitive effects of serotonin to be studied, with implications for the understanding of psychiatric conditions, including depression.

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

open access: yesAdvanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Spiking activity in the visual thalamus is coupled to pupil dynamics across temporal scales.

open access: yesPLoS Biology
The processing of sensory information, even at early stages, is influenced by the internal state of the animal. Internal states, such as arousal, are often characterized by relating neural activity to a single "level" of arousal, defined by a behavioral ...

Hypohidrosis or hyperhidrosis? Ross syndrome

open access: yesDermatologica Sinica, 2016
Ross syndrome is a rare clinical disorder of sweating associated with areflexia and tonic pupil. The most disturbing symptoms are segmental compensatory hyperhidrosis and heat intolerance.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by
