Simultaneous readout of two charge qubits

, 2006
We consider a system of two solid state charge qubits, coupled to a single read-out device, consisting of a single-electron transistor (SET). The conductance of each tunnel junction is influenced by its neighboring qubit, and thus the current through the

Characterization of a commercially available large area, high detection efficiency single-photon avalanche diode

, 2013
We characterize a new commercial, back-illuminated reach-through silicon single-photon avalanche photo diode (SPAD) SAP500 (Laser Components. Inc.), operated in Geiger-mode for purpose of photon counting.

Surgical instrument counting: Current practice and staff perspectives on technological support

Human Factors in Healthcare
Background: Surgical instrument counting is a manual, attention-intensive task of the operating room (OR) nurse. Many labour-saving technologies have been proposed, but implementation remains challenging.

Optimisation of the Read-out Electronics of Muon Drift-Tube Chambers for Very High Background Rates at HL-LHC and Future Colliders

, 2016
In the ATLAS Muon Spectrometer, Monitored Drift Tube (MDT) chambers and sMDT chambers with half of the tube diameter of the MDTs are used for precision muon track reconstruction.

Efficient weighted counting of multiset derangements

Arabian Journal of Mathematics
Abstract We use the Almkvist–Zeilberger algorithm, combined with a weighted version of the Even–Gillis Laguerre integral due to Foata and Zeilberger, in order to efficiently compute weight enumerators of multiset derangements according to the number of cycles.

Cell counting to monitor swab efficiency

Journal of Forensic Sciences
AbstractPlastic bags, such as ziplock bags, have been used to transport illicit materials worldwide; however, very few studies have tried to optimize the recovery of DNA from these items. This study reports on the best combination of swabs and moistening solution for the greatest recovery of cellular material from ziplock bags.

Efficient Prime Counting and the Chebyshev Primes

Journal of Discrete Mathematics, 2013
The function where is the logarithm integral and the number of primes up to is well known to be positive up to the (very large) Skewes' number. Likewise, according to Robin's work, the functions and , where and are Chebyshev summatory functions, are positive if and only if Riemann hypothesis (RH) holds.

TasselNetv2: in-field counting of wheat spikes with context-augmented local regression networks

Plant Methods, 2019
Background Grain yield of wheat is greatly associated with the population of wheat spikes, i.e., $$spike~number~\text {m}^{-2}$$ spikenumberm-2 . To obtain this index in a reliable and efficient way, it is necessary to count wheat spikes accurately and ...
