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 ...

SleepPic. Hardware Developments for a Wearable On-line Sleep and Wake Discrimination System

Dario Floreano, Walter Karlen

The design of wearable systems comes with constraints in computational and power resources. We describe the development of customized hardware for the wearable discrimination of human sleep and wake based on cardio-respiratory signals. The device was desig ...

High-resolution 3D condition survey of a masonry arch bridge using Ground Penetrating Radar

Eugen Brühwiler, Alexis Kalogeropoulos

Condition surveying is essential before rehabilitation and modification of a structure. It implies information collection and analysis for structural performance evaluation. Common condition surveying often requires obstructive and invasive techniques that ...

Spindle positioning in human cells relies on proper centriole formation and on the microcephaly proteins CPAP and STIL

Pierre Gönczy, Petr Strnad, Debora Keller, Fernando Romero Balestra, Gregor Kohlmaier

Patients with MCPH (autosomal recessive primary microcephaly) exhibit impaired brain development, presumably due to the compromised function of neuronal progenitors. Seven MCPH loci have been identified, including one that encodes centrosome protein 4.1 as ...

Adaptive Sleep-Wake Discrimination for Wearable Devices

Dario Floreano, Walter Karlen

Sleep/wake classification systems that rely on phys- iological signals suffer from inter-subject differences that make accurate classification with a single, subject-independent model difficult. To overcome the limitations of inter-subject variability we s ...

Enhancing Pilot Performance with a SymBodic System

Daniel Thalmann, Dario Floreano, Walter Karlen, Sylvain Cardin

Increased fatigue of pilots during long flights can place both humans and machine at high risk. In this paper, we describe our research on a SymBodic (SYMbiotic BODies) system designed to minimize pilot fatigue in a simulated 48 hour mission. The system de ...

Metabolic response of the cerebral cortex following gentle sleep deprivation and modafinil administration

Pierre Magistretti, Jean-Marie Petit, Christophe Kopp

Objectives: The main energy reserve of the brain is glycogen, which is almost exclusively localized in astrocytes. We previously reported that cerebral expression of certain genes related to glycogen metabolism changed following instrumental sleep deprivat ...

TRANSVERSE MODE COUPLING INSTABILITY MEASUREMENTS AT TRANSITION CROSSING IN THE CERN PS

Sandra Aumon

Transition crossing in the CERN PS is critical for the stability of high intensity beams, even with the use of a second order gamma jump scheme. The intense single bunch beam used for the neutron Time-of-Flight facility (n-ToF) needs a controlled longitudi ...

Daylight Exposure and Circadian Efficiency in Office Rooms Equipped with Anidolic Daylighting Systems

Jean-Louis Scartezzini, Mirjam Münch, Friedrich Linhart

Anidolic Daylighting Systems (ADS) typically reduce the daylight flux reaching an office room‟s window section and increase it in the rear of the room. They offer interesting possibilities for the combination of comfortable daylighting and highly energy-ef ...

Functional characterization of the SAS-4-related protein CPAP in centrosome biology of human cells

Gregor Kohlmaier

The centrosome is an organelle that resides at the center of most animal cells and comprises two microtubule-based centriole cylinders surrounded by pericentriolar material (PCM). The centrosome plays a fundamental role for nucleating and organizing a radi ...
