Improvement of two-way continuous-variable quantum key distribution with virtual photon subtraction

, 2017
We propose a method to improve the performance of two-way continuous-variable quantum key distribution protocol by virtual photon subtraction. The Virtual photon subtraction implemented via non-Gaussian post-selection not only enhances the entanglement ...

Eigenspectrum Noise Subtraction Methods in Lattice QCD

, 2010
We propose a new noise subtraction method, which we call "eigenspectrum subtraction", which uses low eigenmode information to suppress statistical noise at low quark mass. This is useful for lattice calculations involving disconnected loops or all-to-all

Young children's use of derived fact strategies in addition and subtraction

Frontiers in Human Neuroscience, 2014
44 children between 6;0 and 7;11 took part in a study of derived fact strategy use. They were assigned to addition and subtraction levels on the basis of calculation pretests.

Causal Perturbation Theory and Differential Renormalization

, 1997
In Causal Perturbation Theory the process of renormalization is precisely equivalent to the extension of time ordered distributions to coincident points. This is achieved by a modified Taylor subtraction on the corresponding test functions.

Learning Scenario to Promote Comprehension of the Meaning of Subtraction

Education Sciences, 2021
The integration of virtual manipulatives in classroom practices facilitates student learning processes. For this, the teacher must understand how to support students in establishing mathematical connections between the manipulation and their ...

Collinear Subtractions in Hadroproduction of Heavy Quarks [PDF]

, 2005
We present a detailed discussion of the collinear subtraction terms needed to establish a massive variable-flavour-number scheme for the one-particle inclusive production of heavy quarks in hadronic collisions.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Autismo e ensino de habilidades acadêmicas: adição e subtração Autism and teaching academic skills: addition and subtraction

Revista Brasileira de Educação Especial, 2007
O ensino de habilidades acadêmicas para pessoas com autismo tem recebido pouca atenção de estudos, provavelmente porque os comprometimentos clássicos do transtorno relacionados à comunicação, interação social e comportamentos são vistos como prioritários

Early Engagement of Parietal Cortex for Subtraction Solving Predicts Longitudinal Gains in Behavioral Fluency in Children

Frontiers in Human Neuroscience, 2020
There is debate in the literature regarding how single-digit arithmetic fluency is achieved over development. While the Fact-retrieval hypothesis suggests that with practice, children shift from quantity-based procedures to verbally retrieving arithmetic

Giant coronary artery fistula: A case report

Radiology Case Reports, 2023
Coronary artery fistulas (CAFs) are abnormal connections of coronary arteries where venous circuits bypass the normal capillaries in the myocardium. CAFs are rare, and most patients are asymptomatic.
