We show that if F :S1 → S1 is a homeomorphism of the unit circle S1 and the rotation number α(F ) of F is irrational, then the Schröder equation Φ ( F(z) = e2πiα(F Φ(z), z ∈ S1, has a unique (up to a multiplicative constant) continuous at a point of the limit set of F solution. We apply this result to prove that if F is a non-trivial continuous and disjoint iteration group or semigroup on S1 an...
S1 Table. Properties of available TCR structures. For each X-ray structure TCR names used in the literature are listed and the relevant TCR chains within one biological unit are indicated. Loci and alleles of the TRAV, TRBV, TRAJ, and TRBJ were assigned using the IMGT Gene/DB [1] and the sequences of the CDR loops are listed for comparison of the different subtypes (Mutations within the framewo...
In this article we present s1, a family of logics that is useful to disprove propositional formulas by means of an anytime approximation process. The systems follows the paradigm of a parameterized family of logics established by Schaerf’s and Cadoli’s system S1. We show that s1 inherits several of the nice properties of S1, while presenting several attractive new properties. The family s1 deal...
The starfish SALMFamide neuropeptides S1 (GFNSALMFamide) and S2 (SGPYSFNSGLTFamide) are the prototypical members of a family of neuropeptides that act as muscle relaxants in echinoderms. Comparison of the bioactivity of S1 and S2 as muscle relaxants has revealed that S2 is ten times more potent than S1. Here we investigated a structural basis for this difference in potency by comparing the bioa...
Three small and distinct satellite double-stranded RNAs (dsRNAs) denoted s1, s1', and s2 were recently described for a Trichomonas vaginalis isolate harboring a dsRNA virus. Since characterization of these satellite dsRNAs might provide insight into the virus replication cycle and virus-host interactions, full-length cDNAs to s1 and s1' dsRNAs were synthesized and sequenced. s1 dsRNA has 688 bp...
Ribosomal protein S1 covalently reacts with approximately one equivalent of iodoacetylethylenediamine (1,5-napthol sulfonate (IAEDANS) or iodoacetylaminofluorescein (IAAF). The product AEDANS-S1 can bind to 30S ribosomal subunits lacking S1 as shown by polyacrylamide-agarose gel electrophoresis AEDANS-S1 and AAF-S1 when added back to S1-depleted 30S subunits modulate poly(U)-dependent polypheny...
Decameric vanadate (V(10)) inhibits the actin-stimulated myosin ATPase activity, noncompetitively with actin or with ATP upon interaction with a high-affinity binding site (K(i) = 0.27 +/- 0.05 microM) in myosin subfragment-1 (S1). The binding of V(10) to S1 can be monitored from titration with V(10) of the fluorescence of S1 labeled at Cys-707 and Cys-697 with N-iodo-acetyl-N'-(5-sulfo-1-napht...
We prove a relation between several easy-to-define numerical invariants of generic knots in H × S, and discuss its implication to contact geometry. 1. Definitions of Invariants The 2-dimensional hyperbolic space H2 is defined to be the upper half plane {(x, y) ∈ R2| y > 0} equipped with the metric ds2 = dx +dy y2 . STH2 is the unit tangent bundle of H2, i.e., the S1-bundle over H2 formed by tan...
تعد نقابة الاشراف الطالبيين احدى مؤسسات الدولة الادارية في العربية الاسلامية ووظيفتها الأساسية هي حفظ أنساب الهاشمين من العلويين والعباسيين أنْ تكون مِدعاةَ الأخرين والعناية شؤونهم الخاصة والعامة.
 وصارت كلمة الأشراف تنسب إلى بيت النبِّي (صلى الله عليه واله وسلم) نسل الحسن والحسين عليهم السلام، وهي وظيفة شريفة ومرتبة نفيسة موضوعها التحدّث على اولاد عليّ بن أبي طالب (عليهم السلام ) فاطمة بنت رسول ...
