BACKGROUND There is still uncertainty concerning the beneficial effects of shoe collar height for ankle sprain prevention and very few data are available in the literature regarding the effect of high-top and low-top shoes on muscle responses during landing. The purpose of this study was to quantify the effect of high-top and low-top shoes on ankle inversion kinematics and pre-landing EMG activ...

It has been repeatedly shown that face inversion affects the recognition of emotional faces. However, previous results are heterogeneous concerning the affected emotions and the influence of presentation time is unclear. We examined the impact of limited presentation time (200 ms) on the face-inversion effect during recognition of basic emotions in 128 healthy young adults. Data analysis reveal...

We used a contextual priming paradigm to examine top-down influences on the face-inversion effect. Adult participants were primed with either faces or Chinese characters and then tested on ambiguous figures that could be perceived as either faces or Chinese characters, dependent on the priming condition. The ambiguous figures differed from one another in their configural information, which is c...

We predict that a lateral electrical current in antiferromagnets can induce nonequilibrium Néel-order fields, i.e., fields whose sign alternates between the spin sublattices, which can trigger ultrafast spin-axis reorientation. Based on microscopic transport theory calculations we identify staggered current-induced fields analogous to the intraband and to the intrinsic interband spin-orbit fiel...

77-year-old woman came to the emergency department with dyspnea and T-wave inversions that became deeper and more diffuse over the next 15 hours (Figure). T waves were inverted, in most leads symmetrically, in all leads except aVR and V1, and the QT interval (604 ms with a QTc of 643 ms) was markedly prolonged. Walder and Spodick described this electrocardiographic pattern as global T-wave inve...

Uterine inversion is a rare condition that is accompanied by massive hemorrhaging and shock, resulting in a maternal emergency. The diagnosis of uterine inversion is often difficult due to massive postpartum hemorrhaging. Ultrasonography is useful for the diagnosis in such conditions, but we do not often encounter typical ultrasonographic images in uterine inversion because it occurs rarely. In...

In this paper, a mechanism is presented to deal with priority inversion in real-time systems when multiple threads of execution synchronize with each other by means of mutual exclusion semaphores coupled with the programming abstraction of condition variables. Traditional priority inheritance solutions focus on addressing priority or deadline inversion as due to the attempt to lock mutual exclu...

Several studies have found learning of biconditional grammars only under intentional rule-search conditions (e.g., Johnstone & Shanks, 2001). Memorization of strings merely led to the learning of chunks. We used a musical grammar, a diatonic inversion, that is a type of biconditional grammar. Participants either were required to memorize a set of grammatical tunes (incidental learning), or were...
