Measurement of e+e− → e+e− and e+e− → λλ at energies up to 36.7 GeV
Abstract The differential cross sections of the reactions e + e − → e + e − and e + e − → λλ are measured at energies between 33.0 and 36.7 GeV. The results agree with the predictions of quantum electrodynamics. A comparison with the standard model of electroweak interaction yields sin 2 θ W = 0.25 ± 0.13.

'Beating the news' with EMBERS: Forecasting Civil Unrest using Open Source Indicators [PDF]
We describe the design, implementation, and evaluation of EMBERS, an automated, 24x7 continuous system for forecasting civil unrest across 10 countries of Latin America using open source indicators such as tweets, news sources, blogs, economic indicators, and other data sources.

Transmission of Renormalized Benzene Circuits
The renormalization equations emerge from a Greenian-matrix solution of the discretized Schrodinger equation. A by-product of these equations is the decimation process, which enables substituted-benzenes to be mapped onto corresponding dimers, that are ...

Progress in existing and planned MST radars [PDF]
Radar systems are described which use two different wind measuring techniques: the partial-reflection drift technique and the mesosphere-stratosphere-troposphere (MST) or Doppler beam-swing radar technique.

Characterization of material composite marble-polyester
In this work we characterize a new material composite, formed with a polyester and crushed white marble mixture. The final purpose is double: to obtain a material for applications sufficiently competitive after an economic viability study, increasing ...

Detailed W0 effects in e+e− → e+e−
Abstract The predicted cross section for the reaction e + e − →e + e − is presented assuming one photon and W 0 exchange. Pure W 0 terms and the W 0 width are included.

Weak shape theorem in first passage percolation with infinite passage times
We consider the model of i.i.d. first passage percolation on $\mathbb{Z}^d$ : we associate with each edge $e$ of the graph a passage time $t(e)$ taking values in $[0,+\infty]$, such that $\mathbb{P}[t(e)p_c(d)$.

Existence of a persistent background of turbulence [PDF]
A plausible scenario for the existence of a persistent back-ground of turbulence in the free atmosphere is described. The MST radar technique is the only existing technique that can be used to describe the morphology of occurrence of turbulence as a ...
