Sorting nexins (SNXs) are regulators of endosomal sorting. For the SNX-BAR subgroup, a Bin/Amphiphysin/Rvs (BAR) domain is vital for formation/stabilization of tubular subdomains that mediate cargo recycling. Here, by analysing the in vitro membrane remodelling properties of all 12 human SNX-BARs, we report that some, but not all, can elicit the formation of tubules with diameters that resemble...

Xiphophorus cortezi males are polymorphic for the pigment pattern vertical bars. In this study, we determined whether X. cortezi females are polymorphic in their preference for this trait by examining both withinand between-individual variation in female preference. There was significantly more variation in female preference within than between individuals using both video animations and live m...

Near-surface mounted (NSM) bars have been used for flexural strengthening of reinforced concrete members. The data available on this type of reinforcement technique are limited and typically, the bars or strips are embedded using an epoxy. Long term durability, abrasion resistance, and compatibility of the repair are important issues with this type of repair. One untested option for embedding t...

We use the ratio L FIR /L B and the IRAS color index S 25 /S 12 (both widely used as indices of relative star formation rates in galaxies) to analyse subsets (containing no known AGNs or merging/interacting galaxies) of: (a) the IRAS Bright Galaxy Sample, (b) galaxies from the optically complete RSA sample which have IRAS detections in all four bands, and (c) a volume-limited IR-unselected samp...

We present here the analysis of morphological and photometric properties of a sample of isolated spirals with (18) and without (11) an active nucleus, based on near-infrared imaging in the J and K’ bands (Paper I). The aim of that comparative analysis is to find the differential properties that could be directly connected with the phenomenon of nuclear activity. We stress the importance of usin...

OBJECTIVE To (1) mechanically evaluate polymethylmethacrylate (PMMA) columns of various sizes and compare them to connecting bar materials (carbon fiber composite, titanium, stainless steel) and (2) compare the properties of an intact PMMA column to those of an acrylic interface. STUDY DESIGN Experimental mechanical study. SAMPLE POPULATION Experiment 1: 6 groups of 6 specimens each; experi...

Predicting the time at which the integral over a stochastic process reaches a target level is a value of interest in many applications. Often, such computations have to be made at low cost, in real time. As an intuitive example that captures many features of this problem class, we choose progress bars, a ubiquitous element of computer user interfaces. These predictors are usually based on simpl...

Secular evolution and fueling is driven by bars in spiral galaxies, and the related dynamical processes are reviewed. It is shown that gravity torques dominate over viscous torques, and produce gas infall to the center. In this infall, the bar wave accepts the angular momentum, which produces its destruction. In the end, a central mass concentration is build, which also contributes to this dest...

The pressing need for psychiatric services within the nation's jails and prisons is well documented. A study sponsored by the American Medical Association in 1973 reported that only 13 percent of the nation's jails had psychiatric services for mentally ill inmates. I This lack is even more disturbing when psychiatric morbidity rates of jailed persons is noted. Rates vary, depending on the natur...

ristina Hidalgo Carcedo, Alberto Luini, Daniela Corda, and colleagues (Consorzio Mario Negri Sud, Santa Maria Imbaro, Italy) suggest that Golgi membranes are chopped up by a protein called BARS before mitosis can occur. Their cell culture studies contrast, however, with results from genetic knock-out experiments. BARS is closely related to the CtBP family of transcriptional repressors needed fo...
