Background In some cases of hemiplegia, the initiation of yawning is associated with involuntary raising of the paralysed arm. Reports are scarce in the literature, probably because the phenomenon has largely been overlooked. Methods We studied six patients from two neurologic units, and compared them with published cases from the last 200 years. Brain imaging typically shows a small vascular l...

Yawning apparatus and exact location of the yawn reflex remains controversial. Yet yawning is a significant behavioural response and potentially a new diagnostic marker of neurological disease. Association between cortisol, electromyography (EMG) and yawning was found in humans supporting Thompson Cortisol Hypothesis (TCH) which complements thermoregulation hypotheses indicating brain cooling o...

Norscia et al. [1] recently reported the first evidence for a sex bias in contagious yawning among humans. Based on previous research showing an indirect connection between contagious yawning and empathy (e.g. [2–4], but see [5,6]) and that levels of empathy appear to be higher in women compared with men (e.g. [7–9]), the authors investigated whether there is also a sex difference in the expres...

The contagious aspect of yawning is a well-known phenomenon that exhibits variation in the human population. Despite the observed variation, few studies have addressed its intra-individual reliability or the factors modulating differences in the susceptibility of healthy volunteers. Due to its obvious biological basis and impairment in diseases like autism and schizophrenia, a better understand...

We present a cooperation scheme for distributed intrusion detection taking into account security-related properties of each individual participating node. This leads to a security overlay network named CIMD (Collaborative Intrusion and Malware Detection1) enabling participants to state objectives for cooperation and find groups for the exchange of security-related data, like monitoring or detec...

Optical Coherence Tomography is an imaging technique characterized by high spatial resolution and noninvasive subsurface detection1. OCT started as an interferometric technique utilizing the newly emerged low coherence or partial coherence light source and time-domain gating to achieve the depth resolution. With additional lateral scans, 2-D or 3D tomographic images can be obtained. The instrum...

This paper describes the design and implementation of a driver drowsiness detection (DDD) system using modified RiscV processor on field-programmable gate array (FPGA). To detect drowsiness, Convolutional Neural Network (CNN) is implemented processor. The CNN trained to classify four primary driver’s expressions, including distraction, natural, sleep, yawn. accuracy 81.07% validation dat...
