u This Letter reports results of a search for radiative production by e+e-annihilation of particles that interact only weakly in matter. The search has been made in the total data set of 115 pb-l acquired with the ASP detector at ~the SLAC storage ring PEP (& = 29 GeV). No anomalous signal was observed. The number of generations of light neutrinos has been limited to NV < 7.5 (90% CL). L' rrnl ...

The presence of viruses in treated and untreated sewage water is a serious issue the agricultural sector as it highly dependent on recycled for irrigation purposes due to shortage fresh resources In this study wastewater has been reviewed evaluate health threats people It cited that such Rotavirus, Norwalk virus, adenovirus, Hepatitis A are common mediators diseases human beings Including respi...

Proof. The first inequality follows from the fact that any allocation of capacity that is feasible in NV is also feasible in DYN, while DYN has the additional freedom to substitute products. The second follows from the fact that for a given demand realization D1,D2, ...,DT , any allocation decision available in DYN is also a feasible allocation in STC. In addition, there are allocation opportun...

The orbital angular momentum (OAM) of light shows great potential in quantum communication. The transmission wavelength for telecom is usually around 1550 nm, while the common quantum information storage and processing devices based on atoms, ions or NV color centers are for photons in visible regime. Here we demonstrate a quantum information interface based on the frequency upconversion for ph...

Adhesion hysteresis is defined as the difference between the work needed to separate two surfaces and that originally gained on bringing them together. Adhesion hysteresis is a common phenomenon in most surface/interface interactions. This paper studies the effects of surface roughness on adhesion hysteresis. We assumed that the surface asperity height distribution is Gaussian. Numerical simula...

Cavity-based large scale quantum information processing (QIP) may involve multiple cavities and require performing various quantum logic operations on qubits distributed in different cavities. Geometric-phase-based quantum computing has drawn much attention recently, which offers advantages against inaccuracies and local fluctuations. In addition, multiqubit gates are particularly appealing and...
