Irish Mathematical Society Bulletin, 1988 This short survey article reviews progress in asymmetric (or public-key) cryptography. Knapsack methods are described along with the successful attacks by Shamir and others. The RSA method and certain generalisations are also considered.

Discrete Mathematics, 1992 A given structure is asymmetric if its automorphism group is trivial. Such structures are usually enumerated by Möbius inversion techniques. The author introduces an asymmetry indicator series and applies it to the systematic classification and enumeration of certain asymmetric structures. Illustrations include rooted trees.

Asymmetric Leptons for Asymmetric Tops
, 2011 We propose an efficient method to explore models which which produce like-sign tops at the LHC, using the total charge asymmetry of single lepton events instead of like-sign dileptons. As an example, the method is implemented on a Z' Model, which can explain the top pair forward-backward asymmetry at Tevatron.

Journal of Contemporary Governance and Public PolicyThe Straits of Malacca and Singapore are among the most strategically important maritime chokepoints in the global trading system. Although conventional threats such as piracy have been managed through regional cooperation, the rapid digitalisation of ...

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentWe present a procedure for handling asymmetric errors. Many results in particle physics are presented as values with different positive and negative errors, and there is no consistent procedure for handling them. We consider the difference between errors quoted using pdfs and using likelihoods, and the difference between the rms spread of a measurement

, 2011 Catalytic asymmetric hydrogenations of prochiral unsaturated compounds, such as olefins, ketones, and imines, have been intensively studied and are considered as a versatile method of the synthesis of chiral compounds due to atom economy and operational ...

, 2017 Asymmetric war can be defined as a way of fighting by a belligerent who rejects the rules of engagement and principles that underlie the strategic culture of its opponent, and uses methods which are unexpected, alien, and not acceptable by the adversary. Thus, it takes advantage of the psychological effects of culture shock and works by defeating one's

Dynamic Conditional Correlations for Asymmetric Processes [PDF]
The paper develops two Dynamic Conditional Correlation (DCC) models, namely the Wishart DCC (wDCC) model. The paper applies the wDCC approach to the exponential GARCH (EGARCH) and GJR models to propose asymmetric DCC models.

Analysis and Geometry in Metric Spaces, 2013 Abstract In this paper we discuss asymmetric length structures and asymmetric metric spaces. A length structure induces a (semi)distance function; by using the total variation formula, a (semi)distance function induces a length. In the first part we identify a topology in the set of paths that best describes when the above operations are

Nature CommunicationsAsymmetric catalysis for enantioselective intramolecular hydroamination of alkenes is a critical method in the construction of enantioenriched nitrogen-containing rings, often prevalent in biologically active compounds and natural products.
