The pressure-tuning Raman spectra of five solid, diiodine heterocyclic thioamide compounds (mbztS)I2 (mbztS = N-methyl2-mercaptobenzothiazole) (1); [(mbztS)2I] [I7] − (2); (pySH)I2 (pySH = 2-mercaptopyridine) (3); [(pySH)(pyS] [I3] − (4); (thpm)(I2)2 or possibly [(thpm)I2] [I3] − (thpm = 2-mercapto-3,4,5,6-tertahydropyrimidine (5) have been measured for pressures up to ∼ 50 kbar using a diamond...

Plastic mulched ridge-furrow irrigation is a useful method to improve crop productivity and decrease salt accumulation in arid saline areas. However, inappropriate fertilizer practices may result ecological environmental problems. In order the resource use efficiency these areas, we investigated effects of different amounts (400 (I1), 300 (I2) 200 (I3) mm) nitrogen application rates (300 (F1) 1...

Introduction: Fig. 1a shows a first-order log-domain filter [1] which is ideally linear and time-invariant (LTI) [1, 2] between the large signal currents i1p and i4p in its input and output transistors (Fig. 1a, assuming i1p > 0). i1p is the sum of an AC input signal iin and a bias Ibias. In traditional implementations, Ibias is a constant. The output ioutp is obtained by subtracting (I2/I3)Ibi...

The M1-muscarinic cholinergic receptor (M1AChR) stimulates the release of inositol phosphates (IPs) but does not activate adenylyl cyclase. The beta-adrenergic receptor (beta-AR) stimulates adenylyl cyclase but has no effect on IP release. Amino acid sequences corresponding to the second (I2) and third (I3) intracellular loops of the turkey erythrocyte beta-AR and a 12-amino acid segment near t...

In this paper we prove identities involving the classical Jacobi theta functions of the form ∑c(i1, i2, i3, i4)θ1(z|τ)1 θ2(z|τ)2 θ3(z|τ)3 θ4(z|τ)4 = 0 with c(i1, i2, i3, i4) ∈ K[Θ], where K is a computable field and Θ := { θ 1 (0|τ) : k ∈ N } ∪ { θ j (0|τ) : k ∈ N and j = 2,3,4 } . We give two algorithms that solve this problem. The second algorithm is simpler and works in a restricted input cl...

Although serotonin 5-HT1A receptors couple to several Gi/o Gprotein subtypes, little is known concerning their differential activation patterns. In this study, in membranes of Chinese hamster ovary cells expressing h5-hydroxytryptamine1A receptors (CHOh5-HT1A), isotherms of 5-HT-stimulated guanosine-5 -O-(3[S]thio)-triphosphate ([S]GTP S) binding were biphasic, suggesting coupling to multiple G...

In this paper color image segmentation is accomplished using MRF model. The problem is formulated as a pixel labeling and the true labels are modeled as the MRF model. The observed color image is assumed to be the degraded version of the true labels. We assume the degradation to be Gaussian distribution. The label estimates are obtained by using Bayesian framework and MAP criterion. The (I1, I2...

to investigate the effect of deficit irrigation on quantitative and qualitative yield of soybean cultivars, an experiment was conducted as split plots based on randomized complete block design with three replications at agricultural research farm, university of guilan, during 2009. main factors were included four irrigation levels based on potential moisture 30-35 (i1), 50-55 (i2), 70-75 (i3) c...

The gamma-aminobutyrate B (GABA(B)) receptor is the first discovered G-protein-coupled receptor (GPCR) that needs two subunits, GB1 and GB2, to form a functional receptor. The GB1 extracellular domain (ECD) binds GABA, and GB2 contains enough molecular determinants for G-protein activation. The precise role of the two subunits in G-protein coupling is investigated. GB1 and GB2 are structurally ...
