Rapid mixing of Swendsen-Wang and single-bond dynamics in two dimensions [PDF]

, 2012
We prove that the spectral gap of the Swendsen-Wang dynamics for the random-cluster model on arbitrary graphs with m edges is bounded above by 16 m log m times the spectral gap of the single-bond (or heat-bath) dynamics.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Photofermentative production of poly-β-hydroxybutyrate (PHB) by purple non-sulfur bacteria using olive oil by-products

Bioresources and Bioprocessing
This study evaluated the ability of six purple non-sulfur bacteria (PNSB) to convert olive oil by-products into poly-β-hydroxybutyrate (PHB). Strains were first independently cultivated in synthetic media with different carbon sources (acetic, lactic and

Polyhydroxybutyrate targets mammalian mitochondria and increases permeability of plasmalemmal and mitochondrial membranes.

PLoS ONE, 2013
Poly(3-hydroxybutyrate) (PHB) is a polyester of 3-hydroxybutyric acid (HB) that is ubiquitously present in all organisms. In higher eukaryotes PHB is found in the length of 10 to 100 HB units and can be present in free form as well as in association with

Three-body Hydrogen Bond Defects Contribute Significantly to the Dielectric Properties of the Liquid Water-Vapor Interface

, 2018
In this Letter, we present a simple model of aqueous interfacial molecular structure and we use this model to isolate the effects of hydrogen bonding on the dielectric properties of the liquid water-vapor interface. By comparing this model to the results

Stringent response and phosphorylations of PHB synthase and PHB depolymerase influence the PHB content of Ralstonia eutropha H16

, 2018
A physiological connection between polyhydroxybutyrate (PHB) metabolism and the formation of polyphosphate (polyP) granules is known in form of the "enhanced biological phosphate removal process" (EBPR) and is used to expurgate phosphate from waste-water.

Regio‐ and Diastereoselective C–C Silylation of Cyclopropyl Acetates Harnessing Fluorinated Poly(pyridyl)Borate Rhodium Catalysts

Chemistry – A European Journal, EarlyView.
Fluorinated poly(pyridyl)borates have been utilized to stabilize rhodium‐diene complexes and as supporting ligands in rhodium‐catalyzed redox‐neutral C–C silylation of cyclopropyl acetates, producing silicon‐containing heterocyclic products, dioxasilolanes.
