Myosin is thought to generate movement of actin filaments via a conformational change between its light-chain domain and its catalytic domain that is driven by the binding of nucleotides and actin. To monitor this change, we have measured distances between a gizzard regulatory light chain (Cys 108) and the active site (near or at Trp 130) of skeletal myosin subfragment 1 (S1) by using luminesce...

شرایط اکولوژیک مثل دسترسی به غذای کافی و مناسب از عواملی است که می‌تواند روی رفتار جانوران تاثیرگذار باشد. حشرات مختلفی در زمان گرسنگی سعی می‌کنند تا رفتارهای آمیزشی طول مدت آمیزش را کاهش دهند. هدف این مطالعه، بررسی اثر بر عملکرد کفشدوزک Hippodamia variegata بود. آزمایش، نرها ماده‌های ۱۰ ۱۵ روزه باکره استفاده شد. هر تکرار، یک نر ماده ۳ ساعت (از ۱۲ الی ۱۵) برای کنار هم قرار داده شدند ‌زمان تاخیر...

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...

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...

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.
