Selectivity in binary fluid mixtures: static and dynamical properties [PDF]

, 2009
Selectivity of particles in a region of space can be achieved by applying external potentials to influence the particles in that region. We investigate static and dynamical properties of size selectivity in binary fluid mixtures of two particles sizes ...

Highly Diastereo- and Enantioselective Allylboration of Aldehydes using alpha-Substituted Allyl/Crotyl Pinacol Boronic Esters via in Situ Generated Borinic Esters [PDF]

, 2013
Readily available, alpha-substituted allyl/crotyl pinacol boronic esters often give low E/Z selectivity (with Z favored) in reactions with aldehydes. We found that addition of nBuLi to the pinacol boronic ester followed by trapping of the alkoxide with ...

Selecting the Selection

, 2016
Modern saturation-based Automated Theorem Provers typically implement the superposition calculus for reasoning about first-order logic with or without equality. Practical implementations of this calculus use a variety of literal selections and term orderings to tame the growth of the search space and help steer proof search.

Functional Organization of Visual Cortex in the Owl Monkey [PDF]

, 2004
In this study, we compared the organization of orientation preference in visual areas V1, V2, and V3. Within these visual areas, we also quantified the relationship between orientation preference and cytochrome oxidase (CO) staining patterns. V1 maps of

Z-Selective Homodimerization of Terminal Olefins with a Ruthenium Metathesis Catalyst [PDF]

, 2011
The cross-metathesis of terminal olefins using a novel ruthenium catalyst results in excellent selectivity for the Z-olefin homodimer. The reaction was found to tolerate a large number of functional groups, solvents, and temperatures while maintaining ...

Polyseme Selection, Lemma Selection and Article Selection

Lexikos, 2017
In linguistics, more specifically in the field of lexical semantics, a lot of attention has been given to polysemy and homonymy. The identification of and distinction between polysemy and homonymy should not be regarded as unproblematic. The lexicographic practice has tradi-tional ways of presenting and treating polysemy and homonymy.

A New Class of High-Selectivity Bandpass Filters With Constant Bandwidth and 5:1 Bandwidth Tuning Ratio

IEEE Access
This paper presents a design for compact bandpass filters (BPFs) that feature high selectivity. This high selectivity is achieved through the use of open-/short-circuited coupled-line segments at the filter’s input and output and a pair of ...

Ação transovariana de lufenuron (50 g/l) sobre adultos de Spodoptera Frugiperda (j. e. smith) (Lepidoptera: Noctuidae) e seu efeito sobre o parasitóide de ovos Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) Transovarian action of lufenuron on adults of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) and its effect on the parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae)

Ciência e Agrotecnologia, 2004
Avaliaram-se a ação transovariana do lufenuron em Spodoptera frugiperda e sua seletividade ao parasitóide de ovos Trichogramma pretiosum. Casais da praga foram isolados em gaiolas de PVC e alimentados com solução de mel a 10% na testemunha, e nos outros ...

Lethal effects of insecticides on adults of Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae)

Entomological Communications, 2022
The predator Eriopis connexa (Germar, 1824) (Coleoptera: Coccinelidae), is an important biological control agent in wheat fields. In this work, we evaluated the lethal effects of fifteen insecticides used in the wheat crop on adults of the predator E ...
