Chiral structures created through the adsorption of molecules onto achiral surfaces play pivotal roles in many fields of science and engineering. Here, we present a systematic study of a novel chiral phenomenon on a surface in terms of organizational chirality, that is, meso-isomerism, through coverage-driven hierarchical polymorphic transitions of supramolecular assemblies of highly symmetric pi-conjugated molecules. Four coverage-dependent phases of dehydrobenzo[12]annulene were uniformly fabricated on Ag(111), exhibiting unique chiral characteristics from the single-molecule level to two-dimensional supramolecular assemblies. All coverage-driven phase transitions stem from adsorption-induced pseudo-diastereomerism, and our observation of a lemniscate-type (infinity) supramolecular configuration clearly reveals a drastic chiral phase transition from an enantiomeric chiral domain to a meso-isomeric achiral domain. These findings provide new insights into controlling two-dimensional chiral architectures on surfaces.

Purpose To deepen our understanding about the development of team performance, the purpose of this paper is to develop a model that explains how ambidexterity and ethical leadership affect knowledge sharing and team performance through within-team competition. Design/methodology/approach This study demonstrates the applicability of ambidexterity and within-team competition by surveying 78 teams from the high-tech and banking industries. This study further presents a three-way interaction among ambidexterity, politics and job complexity. Findings This study finds that both ambidexterity and ethical leadership are positively related to knowledge sharing and team performance through the mediation of team development competition. Originality/value This study confirms that ambidexterity and ethical leadership play critical factors for improving knowledge sharing and team performance through the mediation of team development competition. Furthermore, the moderating effects of politics and job complexity are also confirmed in the research.

Oligomerization of protein into specific quaternary structures plays important biological functions, including regulation of gene expression, enzymes activity, and cell-cell interactions. Here, we report the determination of two crystal structures of the Grimontia hollisae (formally described as Vibrio hollisae) thermostable direct hemolysin (Gh-TDH), a pore-forming toxin. The toxin crystalized in the same space group of P2(1)2(1)2, but with two different crystal packing patterns, each revealing three consistent tetrameric oligomerization forms called Oligomer-I, -II, and -III. A central pore with comparable depth of similar to 50 angstrom but differing in shape and size was observed in all determined toxin tetrameric oligomers. A common motif of a toxin dimer was found in all determined structures, suggesting a plausible minimum functional unit within the tetrameric structure in cell membrane binding and possible hemolytic activity. Our results show that bacterial toxins may form a single or highly symmetric oligomerization state when exerting their biological functions. The dynamic nature of multiple symmetric oligomers formed upon release of the toxin may open a niche for bacteria survival in harsh living environments.
Dual-focal-plane augmented reality head-up display using a single picture generation unit and a single freeform mirror

Two or more focal planes are required in augmented reality head-up displays (AR HUDs) to respectively present basic and interactive driving information to car drivers; whereas, solutions using two separated picture generation units (PGUs) with two sets of optics incur increased cost, reduced reliability, and expanded volume. To develop an AR HUD using a single PGU and a single curved mirror, we propose to set two logically separated regions on a single PGU and optically relay one of them to a new position to create two focal planes. A single freeform mirror acquired through careful optical and mechanical design optimization produces high image quality in an eyebox of 120 mm by 60 mm, simultaneously for a far image (9 m, 10 degrees by 3 degrees) and a near image (2.5 m, 6 degrees by 2 degrees). Finally, an AR HUD product with a compact volume of 8.5 L is fabricated to experimentally verify the design. (C) 2019 Optical Society of America
