Counting operator analysis of the discrete spectrum of some model Hamiltonians

, 2009
The first step in the counting operator analysis of the spectrum of any model Hamiltonian H is the choice of a Hermitean operator M in such a way that the third commutator with H is proportional to the first commutator.

Net on-chip Brillouin gain based on suspended silicon nanowires [PDF]

, 2015
The century-old study of photon-phonon coupling has seen a remarkable revival in the past decade. Driven by early observations of dynamical back-action, the field progressed to ground-state cooling and the counting of individual phonons.

Colour masks in digital image analysis: A technique for modal analyses of quartz saturated plutonic rocks [PDF]

Bulletin of the Geological Society of Finland, 1999
Mineral modes can be calculated quickly and accurately by using colour masks in scanned digital images of stained, quartz saturated plutonic rocks. The image analysis method for determining modal compositions is as accurate as manual point counting, and ...

FPTAS for Counting Monotone CNF

, 2014
A monotone CNF formula is a Boolean formula in conjunctive normal form where each variable appears positively. We design a deterministic fully polynomial-time approximation scheme (FPTAS) for counting the number of satisfying assignments for a given ...

Conformational dynamics of the tetracycline-binding aptamer [PDF]

, 2011
The conformational dynamics induced by ligand binding to the tetracycline-binding aptamer is monitored via stopped-flow fluorescence spectroscopy and time-correlated single photon counting experiments.

HAGN: Hierarchical Attention Guided Network for Crowd Counting

IEEE Access, 2020
In recent years, deep learning based crowd counting networks have achieved significant progress. However, most of them generate rough crowd density maps due to low-resolution features used for estimating crowd distribution, which affects the performance ...

Every steps counts [PDF]

, 2018
This dissertation examines the daily activities of nursing home residents and the role played by nurses and caregivers. The most common activities are sleeping, watching TV and doing nothing. Household activities are extremely rare, as nearly half of these daily tasks are performed by nurses and caregivers.

Multi‐step incremental ADC with extended binary counting

Electronics Letters, 2016
A multi‐step incremental ADC (IADC) with extended binary counting is proposed. It achieves high accuracy by splitting one conversion cycle into two serial steps. During the first step, the ADC works as a first‐order IADC (IADC1).

Quantum optical memory protocols in atomic ensembles

, 2018
We review a series of quantum memory protocols designed to store the quantum information carried by light into atomic ensembles. In particular, we show how a simple semiclassical formalism allows to gain insight into various memory protocols and to ...
