We present plasmonic devices, consisting of periodic arrays of graphene nanoribbons (GNRs) and a graphene sheet waveguide, to achieve controllable plasmon-induced transparency (PIT) by numerical simulation. We analyze the bright and dark elements of the GNRs and graphene-sheet waveguide structure. Results show that applying the gate voltage can electrically tune the PIT spectrum. Adjusting the ...

The idea that embolized xylem vessels can be refilled while adjacent vessels remain under tension is difficult to accept if the cavitated vessels remain hydraulically connected to vessels under tension. A mechanism by which embolized conduits could be hydraulically isolated from adjacent conduits requires the existence of a non-zero contact angle and a flared opening into the bordered pit chamb...

OBJECTIVE To evaluate the association between alpha angle and herniation pit on MRI in asymptomatic hip joints and their associations with demographic variables. MATERIALS AND METHODS Hip MRI of 185 asymptomatic hip joints of 105 adults (age 18 to 80 years) from September 2011 through December 2012 were retrospectively studied. Alpha angles were measured on oblique axial MR images by 2 observ...

Near infrared photoimmunotherapy (NIR-PIT) is a newly developed cancer therapy that relies on the binding of a near-infrared antibody photoabsorber conjugate (APC) to a cancer cell. Subsequent exposure to NIR light selectively induces rapid necrotic cell death on target-expressing cells with minimal off-target effects. When treated with NIR-PIT, targeted cells become swollen, develop blebs and ...

Rhizobium meliloti mutants defective in the phoCDET-encoded phosphate transport system form root nodules on alfalfa plants that fail to fix nitrogen (Fix-). We have previously reported that two classes of second-site mutations can suppress the Fix- phenotype of phoCDET mutants to Fix+. Here we show that one of these suppressor loci (sfx1) contains two genes, orfA and pit, which appear to form a...

Bootstrap methods are widely used in statistics, and bootstrapping of residuals can be especially useful in the regression context. However, difficulties are encountered extending residual resampling to regression settings where residuals are not identically distributed (thus not amenable to bootstrapping)-common examples including logistic or Poisson regression and generalizations to handle cl...

Reward-predictive stimuli augment instrumental reward-seeking in humans, an effect denoted Pavlovian-to-instrumental transfer (PIT), but the role of differential reward value of these stimuli and of emotional conditioned responses in PIT remains unknown. Fifty one participants experienced a Pavlovian phase that associated two stimuli with either 10p (CS10) or 50p (CS50). Next, participants unde...

The fruit canning industry processes large quantities of the clingstone varieties of peach (Prunus persica L. Batch). The occurrence of split-pit formation--the opening of the pit and sometimes splitting of the fruit--causes deterioration of canned fruit quality. The frequency of split-pit formation is influenced by genetic and environmental factors. To increase understanding of the molecular m...

The aim of this study was to evaluate risk factors for occurrence of neonatal passive immune thrombocytopenia (PIT) in pregnancy complicated by idiopathic thrombocytopenic purpura (ITP). We studied 63 pregnant women with ITP and the 66 neonates retrospectively. Neonatal platelet counts were compared with maternal platelet counts, platelet-associated gamma G immunoglobulin (PAIgG) values, and th...

Somatostatin signals through somatostatin receptor subtypes (SSTR) 2 and 5 to attenuate GH secretion. Although expressed in normal pituitary glands and in GH-secreting pituitary tumors, SSTR3 function was unclear, and we have now determined the role of SSTR3 in somatotroph function. Stable rat pituitary tumor cell (GC) transfectants of human SSTR3 (GpSSTR3(WT)) showed suppression of rat (r) GH ...
