Hidden-nucleons neural-network quantum states for the nuclear many-body problem

We generalize the hidden-fermion family of neural network quantum states to encompass both continuous and discrete degrees of freedom and solve the nuclear many-body Schrodinger equation in a systematically improvable fashion. We demonstrate that adding hi ...

A Muscle-Reflex Model of Forelimb and Hindlimb of Felidae Family of Animal with Dynamic Pattern Formation Stimuli

Auke Ijspeert, Azhar Aulia Saputra

Human and animal locomotion are controlled by complex neural circuits, which can also serve as inspiration for designing locomotion controllers for dynamic locomotion in legged robots. We develop a locomotion controller model including a central pattern ge ...

Toward proper evaluation of light dose in indoor office environment by frontal lux meter

Jean-Louis Scartezzini, Ali Motamed, Maira Vieira Dias

The wearable Brazilian illuminance meter “OcuLux” provides the opportunity to monitor continuously pupilar illuminance for indoor environment. The device is calibrated to evaluate the illuminance in lux for the range of 0 to 3500 lux with 23% of precision. ...

Eyewatch, an Innovative Adjustable GDD for the Treatment of Glaucoma - in Vivo Results

Nikolaos Stergiopoulos, André Mermoud, Sylvain Roy, Adan Villamarin, Stéphane Bigler

PURPOSE: To report the in vivo results of a continuously adjustable glaucoma drainage device (GDD) in glaucoma surgery with rabbits. METHODS: Under general anesthesia, the AGDD was implanted on 12 white New-Zealand rabbits for duration of 6 months. The adj ...

Pupil responses derived from outer and inner retinal photo reception are normal in patients with hereditary optic neuropathy

Mirjam Münch, Lorette Leon

We compared the pupil responses originating from outer versus inner retinal photoreception between patients with isolated hereditary optic neuropathy (HON, n = 8) and healthy controls (n = 8). Three different testing protocols were used. For the first two ...

Somatic and axonal LIGHT signaling elicit degenerative and regenerative responses in motoneurons, respectively

Julianne Bobela

A receptor-ligand interaction can evoke a broad range of biological activities in different cell types depending on receptor identity and cell type-specific post-receptor signaling intermediates. Here, we show that the TNF family member LIGHT, known to act ...

In Vivo Testing of a Novel Adjustable Glaucoma Drainage Device

Nikolaos Stergiopoulos, André Mermoud, Sylvain Roy, Adan Villamarin, Stéphane Bigler

PURPOSE. We report on the in vivo testing of a novel noninvasively adjustable glaucoma drainage device (AGDD), which features an adjustable outflow resistance, and assess the safety and efficiency of this implant. METHODS. Under general anesthesia, the AGD ...

Neural correlates of non-retinotopic visual processing and light adaptation

Yvonne Evelina Thunell

In the main part of this thesis, I investigate the neural correlates of nonretinotopic processing. We might intuitively think of the visual representation of the world as retinotopic, as is the case for the organization of most visual brain areas, but in f ...

Intrinsically photosensitive retinal ganglion cells: classification, function and clinical implications

Purpose of review The discovery of a new class of intrinsically photosensitive retinal ganglion cells (ipRGCs) revealed their superior role for various nonvisual biological functions, including the pupil light reflex, and circadian photoentrainment. Recent ...

A two-arm coordination model for phantom limb pain rehabilitation

Ronan Boulic, Eray Molla

Following limb loss, patients usually continue having sensations on their missing limbs as if they were still present. Signicant amount of such sensations are painful and referred as Phantom Limb Pain (PLP). Previous research has shown that providing the p ...

Precise toxigenic ablation of intermediate cells abolishes the "battery" of the cochlear duct

Friedrich Beermann

The extracellular potential of excitable and nonexcitable cells with respect to ground is ∼0 mV. One of the known exceptions in mammals is the cochlear duct, where the potential is ∼80-100 mV, called the endocochlear potential (EP). The EP serves as the "b ...

Circadian and Wake-Dependent Effects on the Pupil Light Reflex in Response to Narrow-Bandwidth Light Pulses

Lorette Leon

PURPOSE. Nonvisual light-dependent functions in humans are conveyed mainly by intrinsically photosensitive retinal ganglion cells, which express melanopsin as photopigment. We aimed to identify the effects of circadian phase and sleepiness across 24 hours ...

Spatio-temporal coupling of the electric and hemodynamic brain responses in humans

Roberto Martuzzi

Our comprehension of human brain functions and their dynamics has been dramatically improved by recent developments in non-invasive imaging techniques. These methods can be divided into two different categories, according to the nature of the measured sign ...
