The interaction between myosin subfragment 1 (S1) and actin filaments after the photolysis of P3-1-(2-nitrophenyl)ethyl ester of ATP (caged ATP) was analyzed with a newly developed freezing system using liquid helium. Actin and S1 (100 microM each) formed a ropelike double-helix characteristic of rigor in the presence of 5 mM caged ATP at room temperature. At 15 ms after photolysis, the ropelik...
We (numerically) construct new static, asymptotically AdS solutions where the conformal infinity is the product of time and S2 × S1. There always exist a family of solutions in which the S1 is not contractible and, for small S1, there are two additional families of solutions in which the S1 smoothly pinches off. This shows that (when fermions are antiperiodic around the S1) there is a quantum p...
From now on X denotes a set and S denotes a family of subsets of X. Now we state the propositions: (1) Let us consider sets X1, X2, a family S1 of subsets of X1, and a family S2 of subsets of X2. Then {a×b, where a is an element of S1, b is an element of S2 : a ∈ S1 and b ∈ S2} = {s, where s is a subset of X1 ×X2 : there exist sets a, b such that a ∈ S1 and b ∈ S2 and s = a × b}. Proof: {a × b,...
In the aforementioned article [S1], Brian Conrad kindly pointed out to us that the proof of Proposition 9.8 is incomplete. We provide here the missing arguments together with a few other corrections and use the opportunity to indicate some new consequences of our results, and also mention some applications of the results in [S1]. In what follows, the supplementary references, including the orig...
We show that if f : S1 × S1 → S1 × S1 is C2, with f(x, t) = (ft(x), t), and the rotation number of ft is equal to t for all t ∈ S1, then f is topologically conjugate to the linear Dehn twist of the torus ( 1 1 0 1 ) . We prove a differentiability result where the assumption that the rotation number of ft is t is weakened to say that the rotation number is strictly monotone in t.
خودناسازگاری در بادام و گونههای جنس آلوسانان یک مکانیسم مهم ژنتیکی است که به این گیاهان اجازه میدهد گردة خودی یا گردههای مشابه را تشخیص دهند و سبب جلوگیری از خودباروری می شود. خودناسازگاری در بادام از نوع گامتوفیتیک است و توسط یک مکان ژنی چندآللی کنترل میشود. مطالعة حاضر بهمنظور شناسایی و انتخاب اولیة نتاج خودسازگار در تلاقیهای کنترلشدة بادام با استفاده از آغازگر اختصاصی sff-sfr ...
Conkunitzin-S1 (Conk-S1) is a 60-residue neurotoxin from the venom of the cone snail Conus striatus that interacts with voltage-gated potassium channels. Conk-S1 shares sequence homology with Kunitz-type proteins but contains only two out of the three highly conserved cysteine bridges, which are typically found in these small, basic protein modules. In this study the three-dimensional structure...
