Fluid shear stress (FSS) has been shown to be an ubiquitous stimulator of mammalian cell metabolism. Although many of the intracellular signal transduction pathways have been characterized, the primary mechanoreceptor for FSS remains unknown. One hypothesis is that the cytoplasmic membrane acts as the receptor for FSS, leading to increased membrane fluidity, which in turn leads to the activatio...

In this paper, an UWB-MIMO antenna with frequency selective surface (FSS) decoupling structure is proposed. To realize antenna system miniaturization and integration, silicon material is applied as substrate. The proposed antenna becomes a very compact construction with dimension of 38.2 × 26.6 × 0.4 mm. The proposed broadband FSS unit consists of four split rectangles and one I-shaped strip. T...

BACKGROUND/AIMS Collateral vessels restore only about 40% of the maximum dilatory reserve after femoral artery occlusion, whereas complete normalization is reached by increased fluid shear stress (FSS). We studied the role of known potent angiogenic growth factors (separately or in combination) in arteriogenesis by determining their expression in FSS-stimulated collaterals and close-to-collater...

BACKGROUND The diagnosis of functional somatic syndromes (FSS) requires 1) presence of somatic symptoms, and 2) absence of medical conditions potentially accounting for these symptoms. Due to the limited feasibility of medical examinations, epidemiological research on FSS has neglected to assess the second criterion. Our objective was therefore to evaluate the implications of considering inform...

The aim of Feature Subset Selection – FSS – algorithms is to select a subset of features from the original set of features that describes a data set according to some importance criterion. To accomplish this task, FSS removes irrelevant and/or redundant features, as they may decrease data quality and reduce several of the desired properties of classifiers induced by supervised learning algorith...

In this study, we demonstrate that fluid shear stress (FSS)-induced actin cytoskeletal reorganization and junctional formation in renal epithelial cells are nearly completely opposite the corresponding changes in vascular endothelial cells (ECs) [Thi MM et al. (2004) Proc Natl Acad Sci USA 101:16483-16488]. Mouse proximal tubule cells (PTCs) were subjected to 5 h of FSS (1 dyn/cm(2)) to investi...

Hughes has defined a class of groups, which we call FSS (finite similarity structure) groups. Each FSS group acts on a compact ultrametric space by local similarities. The best-known example is Thompson’s group V . Guided by previous work on Thompson’s group V , we establish a number of new results about FSS groups. Our main result is that a class of FSS groups are of type F∞. This generalizes ...

Frequency selective surfaces (FSS) have been studied for many years and widely used in different fields ranging from microwave engineering to optical system. Recently, Active Freuqency Selective Surfaces (AFSS) having tunable or reconfigurable frequency response received more and more attention. In this study, a new means of active FSS is reported. By printing the unit elements of FSS on an org...

Deterministic sources of polarization entangled photon pairs on demand are considered as important building block for quantum communication technology. It has been demonstrated that semiconductor quantum dots (QDs), exhibiting a sufficiently small excitonic fine structure splitting (FSS) can be used as triggered, on-chip sources of polarization entangled photon pairs. As-grown QDs usually do no...

BACKGROUND The aim of this study was to clarify the changes in biological measures during autogenic training (AT) sessions and the relationship between these biological measures and the changes in physical and psychological measures induced by continuation of AT in patients with functional somatic syndrome (FSS). We used the salivary amylase (SAMY) level, skin temperature of the finger (TEMP), ...
