Pre-excitation or post-excitation [PDF]
Editor,—We read with great interest the case study by Lau et al entitled “A new ECG sign of an accessory pathway in sinus rhythm: pseudo partial right bundle branch block”.1 However, ventricular pre-excitation can change any part of QRS; the sole …

Isospin structure of one- and two-phonon GDR excitations [PDF]
Isospin is included in the description of Coulomb excitation of multiple giant isovector dipole resonances. In the excitation of even-even nuclei, a relevant portion of the excitation strength is shown to be associated with 1+ two-phonon states, which ...

Roundabout relaxation: collective excitation requires a detour to equilibrium [PDF]
Relaxation to equilibrium after strong and collective excitation is studied, by using a Hamiltonian dynamical system of one dimensional XY model. After an excitation of a domain of $K$ elements, the excitation is concentrated to fewer elements, which are

The paper describes the design of broadband chirp excitation pulses in NMR. We first develop a three stage model for understanding chirp excitation in NMR. We then show how a chirp $ $ pulse can be used to refocus the phase of the chirp excitation pulse. The resulting magnetization still has some phase dispersion in it.

We conduct a detailed study and comparison for the one-degree-of-freedom steady-state vibrations under harmonic driving with a single fractional-order derivative and a distributed-order derivative.

Contribution to research of thermal loads in commercial vehicles powertrain mounts / Приложение к исследованию тепловой нагрузкиопоры силового привода грузового автомобиля / Prilog istraživanju toplotnih opterećenja oslonaca pogonske grupe teretnog motornog vozila [PDF]
Due to the effects of excitations of road micro-roughness and the powertrain as well as due to the conditions of movement (acceleration, braking, curvilinear movement), the weights of commercial vehicles perform complex spatial oscillations. The negative

Harmonic chirp imaging method for ultrasound contrast agent [PDF]
Coded excitation is currently used in medical ultrasound to increase signal-to-noise ratio (SNR) and penetration depth. We propose a chirp excitation method\ud for contrast agents using the second harmonic component of the response.

THE EXCITEMENT OF DISCOVERY [PDF]
I had the good luck to start research at the dawn of molecular biology when it was possible to ask fundamental questions about the nature of the nucleic acids and how information is transferred in living systems. The search for answers led me into many different areas, often with the question of how molecular structure leads to biological function ...

Balanced Noise-Evoked Excitation and Inhibition in Awake Mice CA3
The hippocampus is known as a neuronal structure involved in learning, memory and spatial navigation using multi-sensory cues. However, the basic features of its response to acoustic stimuli without any behavioral tasks (conditioning) remains poorly ...
