Quantitative particle size, microtextural and outline shape analyses of glacigenic sediment reworked by paraglacial debris flows
(2009)Particle size analysis and scanning electron microscopy have been used with some success to differentiate sediments sampled from varying geomorphological environments. In the paraglacial environment, however, discrimination ... -
Quantitative PCR analysis of abundance of airborne propagules of Leptosphaeria species in air samples from different regions of Poland
(2012)When airborne propagules of Leptosphaeria maculans and L. biglobosa were collected in Poland at three ecologically different sites from 1 September to 30 November in 2004 to 2008, using a Hirst-type seven-day volumetric ... -
Quantitative resistance increases the durability of qualitative resistance to Leptosphaeria maculans in Brassica napus
(2010)It has frequently been hypothesized that quantitative resistance increases the durability of qualitative (R-gene mediated) resistance but supporting experimental evidence is rare. To test this hypothesis, near-isogenic ... -
Quantitative resistance to symptomless growth of Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape)
(2009-04)Quantitative resistance to Leptosphaeria maculans in Brassica napus was investigated in field and controlled environments using cultivars Darmor (with quantitative resistance) and Eurol (without quantitative resistance). ... -
A quantitative structure-permeability relationship model for split-thickness skin absorption, reasoning for the choice of the database.
(2018-06-20)The skin is the largest organ in the human body, protecting the body from xenobiotic invasion (1). Local and systemic drugs may also be administered through the skin, therefore the need to measure the permeability of the ... -
Quantitative studies on dispersal of Pseudocercosporella herpotrichoides spores from infected wheat straw by simulated rain
(1983)Splash dispersal ofPseudocercosporella herpotrichoides spores from infected wheat straw was investigated using simulated rainfall (rate 13.8l h−1 m−2, volume mean diameter 2.9 mm) and wind (2 m sec−1) in a raintower/wind ... -
A quantitative technique for analysing robot-human interactions
(Institute of Electrical and Electronics Engineers (IEEE), 2002)This paper proposes a technique for quantitatively describing and analysing robot-human interactions in terms of low-level behavioural criteria (so-called micro-behaviours). In order to demonstrate the usefulness of this ... -
Quantum Based Networks : Analysis of Quantum Teleportation Protocol and Entanglement Swapping
(Springer Nature, 2019-08-18)In this paper we consider the quantum teleportation and entanglement swapping protocols used in quantum based networks for passing information between a sender and receiver. For the teleportation protocol we observe and ... -
Quantum chemical studies on structure activity relationship of natural product polyacetylenes
(2007-02)An extract of the roots of Levisticum officinale L. (Apiaceae) exhibited significant antimycobacterial activity against Mycobacterium fortuitum, where diacetylene compounds were identified as the active components in this ... -
Quantum computing with controlled-NOT and few qubits
(1997)We describe simple quantum networks which allow us to prepare, manipulate and measure quantum entanglement of few qubits. -
Quantum Kerr oscillators' evolution in phase space : Wigner current, symmetries, shear suppression and special states
(2019-03-06)The creation of quantum coherences requires a system to be anharmonic. The simplest such continuous one-dimensional quantum system is the Kerr oscillator. It has a number of interesting symmetries we derive. Its quantum ... -
Quantum loop algebras and l-root operators
(2015-12-01)Let g be a simple Lie algebra and q transcendental. We consider the category C_P of finite-dimensional representations of the quantum loop algebra Uq(Lg) in which the poles of all l-weights belong to specified finite sets ... -
Quantum Primitives
(American Institute of Physics (AIP), 2009)We explore possible characterisations of entanglement classes which may be interpreted as gates acting on globally distributed systems. The cyclic nature of a selection of entanglement gates, primitives, is explored ... -
Quantum protocols for anonymous voting and surveying
(2007-01)We describe quantum protocols for voting and surveying. A key feature of our schemes is the use of entangled states to ensure that the votes are anonymous and to allow the votes to be tallied. The entanglement is distributed ... -
Quantum Randomness in Cryptography—A Survey of Cryptosystems, RNG-Based Ciphers, and QRNGs
(2022-07-27)Cryptography is the study and practice of secure communication with digital data and focuses on confidentiality, integrity, and authentication. Random number generators (RNGs) generate random numbers to enhance security. ... -
Quantum statistics can suppress classical interference
(2002)Classical optical interference experiments correspond to a measurement of the first-order correlation function of the electromagnetic field. The converse of this statement: exper- iments that measure the first order ... -
A Quantum Stochastic Calculus
(2012-11-29)Martingales are fundamental stochastic process used to model the concept of fair game. They have a multitude of applications in the real world that include, random walks, Brownian motion, gamblers fortunes and survival ... -
Quantum stochastic processes
(American Institute of Physics (AIP), 2009)We consider quantum analogues of n-parameter stochastic processes, associated integrals and martingale properties extending classical results obtained in [1, 2, 3], and quantum results in [4, 5, 6, 7, 8, 9, 10].
