Effects on subjective and objective alertness and sleep in response to evening light exposure in older subjects

Evening bright light exposure is reported to ameliorate daytime sleepiness and age-related sleep complaints, and also delays the timing of circadian rhythms. We tested whether evening light exposure given to older adults with sleep–wake complaints would de ...

Global Functional Connectivity Deficits in Schizophrenia Depend on Behavioral State

Roy Salomon

Schizophrenia is a devastating psychiatric illness characterized by deterioration of cognitive and emotional processing. It has been hypothesized that aberrant cortical connectivity is implicated in the disease (Friston, 1998), yet previous studies of func ...

Defect Insensitive Light Emission in Blue Diode Materials Investigated by Electron Microscopy and Transmission Cathodoluminescence

Anas Mouti

We study in this thesis the structural origin of defect insensitive light emission in indium containing group-III nitride ternary alloys grown on sapphire, which are the active materials for the commercially available high brightness blue diodes. These str ...

Informing daylighting design with the Lightsolve approach: why and how

Marilyne Andersen, Magali Bodart

To efficiently and appropriately integrate daylighting strategies in their projects, building designers need reliable methods to address issues such as daily and seasonal variations or the balance between sufficient illumination with visual and thermal com ...

An intuitive daylighting performance analysis and optimization approach

Marilyne Andersen, Magali Bodart

The effective integration of daylighting considerations into the design process requires many issues to be considered simultaneously, such as daily and seasonal variations, illumination, and thermal comfort. To address the need for early integration into t ...

Comparing effects of oligotrophication and upstream hydropower dams on plankton and productivity in perialpine lakes

Alfred Johny Wüest, Martin Schmid

In recent decades, many perialpine lakes have been affected by oligotrophication due to efficient sewage treatment and by altered water turbidity due to upstream hydropower operations. Such simultaneous environmental changes often lead to public debate on ...

Defect-induced changes in the spectral properties of high-Tc cuprates

Giorgio Margaritondo, László Forró, Marco Grioni, Davor Pavuna, Helmuth Berger

Superconductivity in high-Tc cuprates is particularly sensitive to disorder due to the unconventional d-wave pairing symmetry. We investigated effects of disorder on the spectral properties of Bi2Sr2CaCu2O8+ ...

Spontaneous recovery of deficits in spatial memory and cholinergic potentiation of NMDA in CA1 neurons during chronic lithium treatment

Henry Markram

The therapeutic action of lithium in affective disorders is still unclear. One effect of lithium is to deplete membrane inositol and consequently to exhaust the phosphoinositide (PI) pathway. Under chronic lithium treatment, rats showed persistent performa ...
