OBJECTIVES We studied the triggering mechanism for neurally mediated syncope. BACKGROUND Although increased transient sympathetic tone is thought to be necessary for the development of neurally mediated syncope, little is known about the triggering mechanism for neurally mediated syncope. METHODS Plasma epinephrine (EP) and norepinephrine (NE) levels were assessed in 20 syncope patients dur...

As noted above, 3D imaging on an SEM requires two images, corresponding to the parallax of the human eyes. While there are some different ways in which these stereoscopic images can be obtained, the most common are: (1) tilting the sample to acquire images from different angles (stage tilting), and (2) changing the direction of the incident electron beam to acquire images from different angles ...

Model calculations of Langmuir monolayers: Pressure effects on tilting behavior of idealized amphiphiles" (1996). Model amphiphiles consisting of lines of Lennard-Jones ͑LJ͒ centers are investigated to determine the effect of pressure and molecular geometry on ground-state tilting behavior. Both the amphiphile length and the intramolecular distance between LJ centers is varied. The results give g...

PURPOSE The purpose of this study was to assess the effects of the passive 45-degree reverse Trendelenburg position and graduated compression stockings (GCS) on plasma tissue factor pathway inhibitor (TFPI) and endothelin-1 levels in a group of volunteers. METHODS Ten healthy subjects lay on an examining table for 30 minutes while baseline measurements were made. The table was then tilted to ...

Bootstrap tilting conndence intervals could be the method of choice in many applications for reasons of both speed and accuracy. With the right implementation , tilting intervals are 37 times as fast as bootstrap BC-a limits, in terms of the number of bootstrap samples needed for comparable simulation accuracy. Thus 100 bootstrap samples might suuce instead of 3700. Tilting limits have other de...

In this paper, we show that the tilting modules over a clustertilted algebra A lift to tilting objects in the associated cluster category CH . As a first application, we describe the induced exchange relation for tilting Amodules arising from the exchange relation for tilting object in CH . As a second application, we exhibit tilting A-modules having cluster-tilted endomorphism algebras. Cluste...

Let M be a module over an associative ring R and σ[M ] the category of M -subgenerated modules. Generalizing the notion of a projective generator in σ[M ], a module P ∈ σ[M ] is called tilting in σ[M ] if (i) P is projective in the category of P -generated modules, (ii) every P -generated module is P presented, and (iii) σ[P ] = σ[M ]. We call P self-tilting if it is tilting in σ[P ]. Examples ...

The assembly of microdevices is currently done mainly with the pick and place method. However, this method is slow and expensive for assembly requiring high precision. Thus, the development of a new fast, yet highly precise method of assembly is the focus of current research. Self-assembly in liquid medium, where microdevices spontaneously arrange themselves into more complex systems using capi...
