Few studies have investigated the prevalence of shaking and smothering and whether they are associated with co-sleeping. In Japan, co-sleeping is common during infancy and early childhood. This study investigates the prevalence of shaking and smothering and their associations with co-sleeping among 4-month-old infants in Japan. A questionnaire was administered to mothers who participated in a 4...

Head-shaking nystagmus. Head-Shaking Nystagmus (HSN) is a latent spontaneous vestibular nystagmus provoked by rapid passive head shaking around a vertical axis. HSN is not specific in distinguishing peripheral hypofunction from more central vestibular imbalances. This test is an excellent bedside test for detecting unilateral vestibular hypofunction but further rotatory and caloric testing will...

Pauli crystals are ordered geometric structures that emerge in trapped noninteracting fermionic systems due to their underlying repulsion. The deformation of - often called melting has been recently observed experiments, but the mechanism leads it remains unclear. We address this question by studying dynamics N=6 fermions as a function periodic driving and experimental imperfections trap (aniso...

Thermoviridin appeared to be an organic acid which was dialyzable. The antibiotic showed maximum absorption in the range of 268 to 272 m,u. Thermoviridin was primarily active against the gram positive bacteria tested. A preliminary toxicity test in mice, consisting of a single intraperitoneal injection of 32 mg of material which had 25 thermoviridin units per mg, did not cause death in any case.

Limb-shaking is a specific clinical feature of transient ischaemic attacks that has been associated with a high-grade stenosis or occlusion of the internal carotid artery. The aim of this study was to describe the clinical characteristics of limb-shaking in patients with internal carotid artery occlusion and to investigate whether patients with limb-shaking have a worse haemodynamic state of th...

OBJECTIVE To document the resolution of oscillatory head movements following surgical realignment of the eyes in children with infantile esotropia and nystagmus. METHOD Retrospective review of 3 children who had infantile esotropia, nystagmus, and unexplained head shaking or head nodding. RESULTS Strabismus surgery restored ocular alignment and produced resolution of the head shaking in all...

Visually-guided locomotion is important for autonomous robotics. However, there are several difficulties, for instance, the head shaking that results from the robot locomotion itself that constraints stable image acquisition and the possibility to rely on that information to act accordingly. In this article, we propose a controller architecture that is able to generate locomotion for a quadrupe...

We study here the spontaneous clustering of a submonolayer grains under horizontal circular shaking. The occurs when increasing oscillation amplitude beyond threshold. dense area travels in fashion at driving frequency, which even exceeds speed driving. It turns out that observed is due to formation density waves. analysis phenomenological model shows instability uniform profile arises by and c...

Electromyographic (EMG) activity was recorded in < or = 12 neck muscles in four alert monkeys whose heads were unrestrained to describe the spatial and temporal patterns of neck muscle activation accompanying a large range of head postures and movements. Some head postures and movements were elicited by training animals to generate gaze shifts to visual targets. Other spontaneous head movements...
