This paper starts with a brief history of Natural Logic from its origins to the most recent work on implicatives. It then describes on-going attempts to represent the meanings of so-called ‘evaluative adjectives’ in these terms based on what linguists have traditionally assumed about constructions such as NP was stupid to VP, NP was not lucky to VP that have been described as factive. It turns ...

In functional genomics studies, research is dedicated to unveiling the function of genes using gene-knockouts, model organisms in which a gene is artificially inactivated. The idea is that, by knocking out the gene, the provoked phenotype would inform us about the function of the gene. Still, the function of many genes cannot be elucidated, because disruption of conserved sequences, including p...

This article examines the scope for strategies to build natural assets in the hands of low-income individuals and communities. Natural assets include sources of raw materials such as forests and fisheries, and the airsheds, lands, and water bodies that provide environmental sinks for the disposal of wastes. These resources become assets when people have rights to access their benefits. Four str...

Recent research on the chemistry of natural products from the author's group that led to the receipt of the ACS Ernest Guenther Award in the Chemistry of Natural Products is reviewed. REDOR NMR and synthetic studies established the T-taxol conformation as the bioactive tubulin-binding conformation, and these results were confirmed by the synthesis of compounds which clearly owed their activity ...

The quinolones have evolved from antibacterial agents with a limited spectrum of predominantly anti-gram-negative antimicrobial activity and a restricted number of indications to a class of widely used oral (and, in some cases, intravenous) antibiotics with extensive indications for infections caused by many bacterial pathogens in most body tissues and fluids. This evolutionary pattern has aris...

We propose a model of natural language inference which identifies valid inferences by their lexical and syntactic features, without full semantic interpretation. We extend past work in natural logic, which has focused on semantic containment and monotonicity, by incorporating both semantic exclusion and implicativity. Our model decomposes an inference problem into a sequence of atomic edits lin...

Rodriguez Villegas expressed the Mahler measure of a polynomial in terms of an infinite series. Lück’s combinatorial L-torsion leads to similar series expressions for the Gromov norm of a knot complement. In this note we show that those formulae yield interesting power series expansions for the logarithm function. This generalizes an infinite series of Lehmer for the natural logarithm of 4. 1 T...

A wound is a disruption of the normal anatomical structure and function of a tissue. Wounds cure in an orderly and timely repair process which is characterized by three dynamic and interactive phases: inflammation, proliferation and the remodeling. The present review was designed to elaborate the cellular and molecular targets for plant secondary metabolites that target the various aspects of w...
