Recent studies show that neutron spin echo spectroscopy (NSE) can reveal long-range protein domain motions on nanometer lengthscales and on nanosecond to microsecond timescales. This unique capability of NSE provides new opportunities to understand protein dynamics and functions, such as how binding signals are propagated in a protein to distal sites. Here we review our applications of NSE to t...

Many problems involving the interaction of an elastic structure and a viscous fluid can be solved by the immersed boundary (IB) method. In the IB approach to such problems, the elastic forces generated by the immersed structure are applied to the surrounding fluid, and the motion of the immersed structure is determined by the local motion of the fluid. Recently, the IB method has been extended ...

Abstract This study was conducted to observe Bali cows’ primipara reproductive performance between natural mating and artificial insemination. Fifty cows owned by 44 farmers in Central Lombok Regency, West Nusa Tenggara Province, were used as the research sample at first mating; 19 subjected (NM) 31 insemination (AI). Farmer’s profile data, rearing system, (the age of puberty, mating, gestation...

The formaldehyde molecule is an important model system for understanding dynamical processes in small polyatomic molecules. However, prior to this work, there have been no reports of a resonance-enhanced multiphoton ionization (REMPI) detection scheme for formaldehyde suitable for rovibrationally state-selective detection in molecular beam scattering experiments. Previously reported tunable REM...

background: evaluating the landmarks for rotation of the distal femur is a challenge for orthopedic surgeons. although the posterior femoral condyle axis is a good landmark for surgeons, the surgical transepicondylar axis may be a better option with the help of preoperative ct scanning. the purpose of this study was to ascertain relationships among the axes’ guiding distal femur rotational alig...

The bio-stimulation technique offers a potentially useful and practical way for reproductive performance in rams. Reports on how bio-stimulation affects sexual potency rams are scarce: Knowledge of how rams respond to bio-stimulation is useful for persons who involved in semen collection; "hand" (controlled) mating, and the administration of sexual performance evaluations. The reduction of the ...

‎the frobenius complement of a given frobenius group acts on its kernel‎. ‎the scheme which is arisen from the orbitals of this action is called ferrero pair scheme‎. ‎in this paper‎, ‎we show that the fibers of a ferrero pair scheme consist of exactly one singleton fiber and every two fibers with more than one point have the same cardinality‎. ‎moreover‎, ‎it is shown that the restriction of a...

We develop two isogeometric divergence-conforming collocation schemes for incompressible flow. The first is based on the standard, velocity–pressure formulation of Navier–Stokes equations, while second rotational form and includes vorticity as an unknown in addition to velocity pressure. describe process discretizing each using B-splines that conform a discrete de Rham complex collocating gover...
