Synkinetic movement of the mandible with ocular movement is a rare anomaly. Carmichael and Critchley (1925) noticed that, when the eyes were rapidly turned horizontally first to one side and then to the other, there was protrusion of the mandible with deviation to the contralateral side. The movement may be associated with depression of the contralateral and raising of the ipsilateral eyebrow. ...

This article addresses the syntax of the notorious tough(-movement) construction (TC) in English. TCs exhibit a range of apparently contradictory empirical properties suggesting that their derivation involves the application of both A-movement and A-movement operations. Given that within previous Principles and Parameters models TCs have remained “unexplained and in principle unexplainable” (Ho...

In the early 20th century, after hundreds of years of gradual decline, the California condor emerged as an object of intensive scientific study, an important conservation target, and a cultural icon of the American wilderness preservation movement. Early condor researchers generally believed that the species’ survival depended upon the preservation of its wilderness habitat. However, beginning ...

Membranes in cell-wall-free dividing endosperm cells of Haemanthus were examined after postfixation with osmium tetroxide-potassium ferrocyanide. We found that preservation and staining of membranes in metaphase cells was highly variable. Even adjacent cells often showed different degrees of preservation of membrane. However, this method does reveal a much more extensive membrane system in the ...

This work is devoted to the proposal of a new flux limiter that makes the algebraic flux correction finite element scheme linearity and positivity preserving on general simplicial meshes. Minimal assumptions on the limiter are given in order to guarantee the validity of the discrete maximum principle, and then a precise definition of it is proposed and analyzed. Numerical results for convection...

The durations and trajectories of our saccadic eye movements are remarkably stereotyped. We have no voluntary control over these properties but they are determined by the movement amplitude and, to a smaller extent, also by the movement direction and initial eye orientation. Here we show that the stereotyped durations and trajectories are optimal for minimizing the variability in saccade endpoi...

Humans show a spontaneous tendency to increase the velocity of their movements depending on the linear extent of their trajectory in order to keep execution time approximately constant. Termed the isochrony principle, this compensatory mechanism refers to the observation that the velocity of voluntary movements increases proportionally with their linear extension. Although there is a wealth of ...

Activity of motor cortex pyramidal tract neurons (PTNs) was recorded in monkeys making large (20 degrees), high velocity and small (1 to 2 degrees), low velocity pronation-supination arm movements in a visual pursuit-tracking paradigm. Antidromic response latencies (ADLs) or PTNs were examined in relation to PTN modulation with the large and small movements to test the hypothesis that PTNs woul...

The development of new digital technologies was predicted to be a boon for environmental activism. Internet and social media platforms were expected facilitate broad bottom-up change, enabling activists worldwide communicate organize more effectively. However, the emergence may not have revolutionized methods impacts activist organizations, especially movement, wherein meaningful change has yet...

Infertility is a very disastrous side effect in young females, especially in traditional male-dominated societies. The aim of this talk is to discuss the possible ways for fertility preservation in both man and woman. Another aspect is to how to predict women at threat of premature ovarian failure. It will also illustrate the association of cytochrome P450 (CYP2C19) polymorphism with ovarian to...
