Collar and tie men: the smallest trefoil knot reported to date has been prepared by an active metal template synthesis. Copper(I) ions are able to constrain the well-designed structure so that it can form the loops by complexing to the bipyridine moieties in the core of the thread and the two ends of the entangled lace on opposite faces of the loop, before acting as a catalyst to close the lace.

Optogenetic systems enable precise spatial and temporal control of cell behavior. We engineered a light-activated CRISPR-Cas9 effector (LACE) system that induces transcription of endogenous genes in the presence of blue light. This was accomplished by fusing the light-inducible heterodimerizing proteins CRY2 and CIB1 to a transactivation domain and the catalytically inactive dCas9, respectively...

INTRODUCTION This report describes InterLACE (Interface to LACE), a natural language and graphical interface to the LACE (Land Air Combat in ERIC) military simulation system from Rome Air Development Center, Grifiss Air Force Base, NY [Anken 89]. Our research group at NCARAI has special interest in such related issues as the mental modeling of spatial information, multimodal human-computer inte...

Complex deformable webs like lace fabrics are amongst the most complicated materials to be inspected without any human intervention. The ability of such webs to deform easily, along with their complex patterns, presents a challenging problem for any machine vision system. Their pattern complexity makes it very difficult to use any global image processing or rulebased techniques for inspection, ...

The current article presents the process of situated modeling in the drawing workshop for bobbin lace developed and implemented in the Núcleo de Produção Artesanal Rendeiras da Vila, in Ponta Negra, Natal-Brasil. The workshop aimed to rescue the domain over the product in the production of bobbin lace through capacitation of both experienced and novice craftswomen. The modeling of the drawing w...

BACKGROUND/AIMS Although various drugs can be used in adults for Helicobacter pylori eradication in adults, treatment options are limited in children. The aim of this study was to compare the effects of the standard lansoprazole, amoxicillin, and clarithromycin (LAC) protocol to those of LAC+vitamin E (LACE) combination for H. pylori eradication. MATERIALS AND METHODS The study included 90 ch...

Evidence Summary In 2007, the Medicare Payment Advisory Committee reported that 18% of hospital admissions resulted in a readmission, of which 76% were potentially avoidable.1 The development of a clinical decision rule to identify patients at risk of readmission could aid in directing interventions and resources, potentially improving cost-effectiveness of care and reducing postdischarge morta...

BACKGROUND Little information is available regarding the ankle braces orthopaedic sports medicine clinicians recommend or clinicians' concerns that may influence their decisions to recommend use of an ankle brace. HYPOTHESES (1) Clinicians most frequently recommend lace-up braces with straps. (2) Clinicians who are concerned about potential adverse side effects from ankle brace use are less l...

This study examines some of the potential mechanisms of resistance in selected Pieris (Ericaceae) taxa to the Andromeda lace bug, Stephanitis takeyai Drake and Maa, based on differences in resistance to lace bug feeding, and the possible role of leaf parameters such as leaf wax, toughness, nutrient composition, and stomatal characters in plant resistance. Experiments with extracts of leaf-surf...
