Exchange Currents for Hypernuclear Magnetic Moments
, 1997 The meson(K and $\pi$) exchange currents for the hypernuclear magnetic moments are calculated using the effective Lagrangian method. The seagull diagram, the mesonic diagram and the $\Sigma^0$-excitation diagram are considered.

FEBS Letters, EarlyView.Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

Automatic extraction of corollaries from semantic structure of text
Open Engineering, 2016 The aim of this study is to develop an algorithm for automatic representation of the text of natural language as a formal system for the subsequent automatic extraction as reasonable answers to profound questions in the context of the text, and the deep ...

Aristotelian Diagrams as Logic Diagrams
AbstractRecently, diagrams are more seen as logical systems. Curiously, Aristotelian diagrams, such as the square of opposition, have mostly been excluded from this. In this paper we challenge this prejudice and show that Aristotelian diagrams can be considered as proper logic diagrams that can be used to draw inferences.

Journal of Knot Theory and Its Ramifications, 2016 We call a delta diagram any diagram of a knot or link whose regions (including the unbounded one) have 3, 4, or 5 sides. We prove that any knot or link admits a delta diagram. We define and estimate combinatorial link invariants stemming from this definition.

FEBS Letters, EarlyView.Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

Liftings of Diagrams of Semilattices by Diagrams of Dimension Groups [PDF]
Proceedings of the London Mathematical Society, 2003 We investigate categorical and amalgamation properties of the functor Idc assigning to every partially ordered abelian group G its semilattice of compact ideals Idc G. Our main result is the following. Theorem 1. Every diagram of finite Boolean semilattices indexed by a finite dismantlable partially ordered set can be lifted, with respect to the Idc ...

FEBS Letters, EarlyView.Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.
