New supplementary conditions are proposed for the two-dimensional Neumann–Kelvin problem describing the forward motion of a surface-piercing body. They lead to the absence of waves behind the body, and hence, the wave resistance is equal to zero. Moreover, for the body with symmetry about vertical axis the total resistance to the forward motion (the sum of wave and spray resistance) also vanish...

The function of the pylorus and the pyloric antrum in the control of gastric emptying has been studied in an isolated rat stomach-duodenum preparation. Pressures in the body and pyloric antrum and flow through the duodenum were recorded using electronic transducers. Vigorous peristalsis and episodic flow were induced by electrical stimulation. The pylorus is normally open until it is transientl...

The complex scaling method permits calculations of few-body resonances with the correct asymptotic behaviour using a simple box boundary condition at a sufficiently large distance. This is also valid for systems involving more than one charged particle. We first apply the method on two-body systems. Three-body systems are then investigated by use of the (complex scaled) hyperspheric adiabatic e...

We present a new three dimensional many-body Hamiltonian with threebody and five-body interactions. We obtain the exact ground state as well as some excited states of this Hamiltonian for arbitrary number of particles. These exact wave-functions describe a novel correlations. Finally, we generalize these three dimensional results to arbitrary higher dimensions. PACS numbers: 03.65.Ge, 05.30.-d ...

A 56-year-old man presented with hypothermia (rectal temperature of 30.18C) and hypotension after being found by emergency medical services (EMS) on his basement floor. A 12-lead electrocardiogram (ECG) revealed normal sinus rhythm with a rate of 62 bpm, right bundle branch block, prolonged QT interval (QTc of 564 ms), wide QRS (110 ms), and a prominent J wave in the precordial leads (Fig. 1). ...

Four identical spinless bosons with purely attractive two-body short-range interactions and repulsive three-body interactions under external spherically symmetric harmonic confinement are considered. The repulsive three-body potential prevents the formation of deeply-bound states with molecular character. The low-energy spectrum with vanishing orbital angular momentum and positive parity for in...

[1] We constrain the spatial variation of P‐wave (tP*) and S‐wave (tS*) attenuation by inverting 190,000 teleseismic P‐ and S‐wave spectra up to 0.8 Hz. These spectra are derived from 250 deep earthquakes recorded at 880 broadband global and regional network stations. The variance and ratios of tP* and tS* values are consistent with PREM’s upper mantle velocity and Q structures and conventional...

Unsteady viscous free-surface waves generated by a three-dimensional submerged body moving in an incompressible fluid of infinite depth are investigated analytically. It is assumed that the body experiences a Heaviside step change in velocity at the initial instant. Two categories of the velocity change, (i) from zero to a constant and (ii) from a constant to zero, will be analyzed. The flow is...
