Evidence for the eta(b)(2S) and Observation of h(b)(1P) -> eta(b)(1S)gamma and h(b)(2P) -> eta(b)(1S)gamma

Mingkui Wang, Olivier Schneider, Chao Wang, Aurelio Bay, Remi Léandre Albert Louvot

We report the first evidence for the eta(b)(2S) using the h(b)(2P) -> eta(b)(2S)gamma transition and the first observation of the h(b)(1P) -> eta(b)(1S)gamma and h(b)(2P) -> eta(b)(1S)gamma transitions. The mass and width of the eta(b)(1S) and eta(b)(2S) a ...

High-Level Energy Estimation in the Sub-VT Domain: Simulation and Measurement of a Cardiac Event Detector

Yusuf Leblebici, Omer Can Akgun

This paper presents a flow that is suitable to estimate energy dissipation of digital standard-cell based designs which are determined to operate in the subthreshold regime. The flow is applicable on gate-level netlists, where back-annotated toggle informa ...

A Handheld Probe for beta(+)-Emitting Radiotracer Detection in Surgery, Biopsy and Medical Diagnostics based on Silicon Photomultipliers

Edoardo Charbon, Claudio Bruschini, Christian Mester

We present a new, handheld probe for radiotracer detection in vivo and inside operating theatres, where PET scanners cannot be used for radioguided surgery. The device is based on scintillation detectors optically coupled to Silicon Photomultipliers (SiPMs ...

Observation of a Charmoniumlike Enhancement in the γγ→ωJ/ψ Process

Olivier Schneider, Chao Wang, Remi Léandre Albert Louvot

We report the results of a search for a charmoniumlike state produced in the process gamma gamma -> omega J/psi in the 3.9-4.2 GeV = c(2) mass region. We observe a significant enhancement, which is well described by a resonant shape with mass M = (3915 +/- ...

Energy Dissipation Reduction of a Cardiac Event Detector in the Sub-Vt Domain By Architectural Folding

Yusuf Leblebici, Omer Can Akgun

This manuscript presents the digital hardware realization of a wavelet based event detector for cardiac pacemaker applications. The architecture of the detector is partially folded to minimize hardware cost. An energy model is applied to evaluate the energ ...

Structural properties of naked gold nanoparticles formed by synchrotron X-ray irradiation

Giorgio Margaritondo

The formation of colloidal unmodified (naked) gold nanoparticles is investigated by irradiation of a precursor solution with X-rays from a synchrotron source. An interesting morphological evolution as a function of exposure time, from cross-linked network- ...

Focus/detector system of an x-ray apparatus for generating phase contrast recordings

A focus/detector system of an X-ray apparatus and a method for generating projective or tomographic phase contrast recordings, are disclosed. In an embodiment of the system, the system includes a beam source equipped with a focus and a focus-side source gr ...
