N-terminal Domain of SARS-CoV-2 Spike Protein In article number 2100152, Yao Li, Tong Wang, Haipeng Gong, and co-workers propose the “wedge” model to demonstrate regulatory function domain (NTD) protein. The NTD typically wedges in prohibit receptor binding domain's (RBD's) movements it occasionally moves out allow RBD tilt downward.

L. W. Schultheis and D. A. Robinson showed that the axis of the rotational vestibuloocular reflex (RVOR) cannot be altered by visual-vestibular mismatch ("cross-axis adaptation") when the vestibulocerebellum is lesioned. This suggests that the cerebellum may calibrate the axis of eye velocity of the RVOR under natural conditions. Thus we asked whether patients with cerebellar disease have alter...

Research on the syntax of negation has produced a lively debate in the literature. One of the central issues concerns the status of NegP functional projections exist in the phrase structure of natural language (see Pollock 1989, Laka 1994, Haegeman 1995, Zanuttini 1991, 1997), or whether negation elements should be more properly assimilated to adverbial (modificatory) phrases (cf. Holmberg and ...

Downward movement and sideward movement necessarily leave a trace that is not c-commanded by the head of the chain and hence violate the PBC. Under a strict interpretation of the PBC, head movement is also banned because the head of the chain in head movement cannot c-command its trace. Likewise, remnant movement would be never permissible, because it leaves an unbound trace within a remnant ca...

We examine a dynamic model for the disruption of information flow in hierarchical social networks by considering the vertex-pursuit game Seepage played in directed acyclic graphs (DAGs). In Seepage, agents attempt to block the movement of an intruder who moves downward from the source node to a sink. We propose a generalized stochastic model for DAGs with given expected total degree sequence. S...

Previous studies suggested that sudden stratospheric warmings (SSW) change the global atmosphere from troposphere to thermosphere/ionosphere. We report low-latitude O+ and H+ composition at 840-km altitude during 2009 SSW, with DMSP satellite morning measurements. Our results indicate variation around 30-km modulates ion exchange between ionosphere protonosphere via vertical field-aligned plasm...

BACKGROUND Aims of this study were to assess the maximum displacement of tracheal tube tip during head-neck movement in children, and to evaluate the appropriateness of the intubation depth marks on the Microcuff Paediatric Endotracheal Tube regarding the risk of inadvertent extubation and endobronchial intubation. METHODS We studied children, aged from birth to adolescence, undergoing cardia...

The Fauconnier-Ladusaw analysis of negative polarity licensing (that NPIs are licensed in the scope of downward entailing operators) continues to be the benchmark theory of negative polarity. In this paper, I consider some of the moves that are needed to maintain its basic intuition in some recalcitrant arenas: negative polarity licensing by only, adversatives, superlatives, and conditionals. W...
