Red Blood Cell Membrane Mechanics Using Discrete Exterior Calculus (DEC) and Optimization. [PDF]

open access: yesInt J Numer Method Biomed Eng
We present a novel DEC approach for calculating RBC shapes applicable to other cell types and membrane problems. We derive an energy minimization equation that can be solved semi‐implicitly, and a Lie derivative method to control node spacing. This novel work should aid computational modeling in many biological situations.

Differently N‐Capped Analogues of Fmoc‐FF

open access: yesChemistry – A European Journal, Volume 29, Issue 28, May 16, 2023., 2023
Fmoc‐FF analogues were collected and analyzed in their morphological, mechanical, and functional features, highlighting the effects caused by the Fmoc‐ modification. Abstract Short and ultra‐short peptides have been recently envisioned as excellent building blocks for the formulation of hydrogels with appealing properties.

Aspects of topology of condensates and knotted solitons in condensed matter systems [PDF]

open access: yes, 1992
The knotted solitons introduced by Faddeev and Niemi is presently a subject of great interest in particle and mathematical physics. In this paper we give a condensed matter interpretation of the recent results of Faddeev and Niemi.Comment: v2: Added a ...

Direct Methanation and Storage Concepts for the Flexibilization of Biogas Plants

open access: yesChemical Engineering &Technology, Volume 46, Issue 3, Page 579-586, March 2023., 2023
Enrichment of the methane fraction in a biogas mixture is a possibility, though challenging, to optimize the existing biogas plants by using excess power. The methanation process and the consequent heat release are studied in a laboratory biogas plant with an innovative heat pipe injector system for cooling the enriched biogas and remixing the biomass ...

Net‐mineralization of organic matter and greenhouse gas emissions from Quebracho tannin‐enriched manure applied to acidic and alkaline soils

open access: yesJournal of Plant Nutrition and Soil Science, Volume 184, Issue 5, Page 530-542, October 2021., 2021
Abstract Background Mitigation strategies to reduce greenhouse gas emissions, ammonia volatilization, and nitrate leaching from agriculture are important for the management of environmental pollution and climate change. Tannins, which are water‐soluble polyphenolic compounds, were found to reduce emissions in animal husbandry systems when supplemented ...

What can gauge-gravity duality teach us about condensed matter physics? [PDF]

open access: yes, 2012
I discuss the impact of gauge-gravity duality on our understanding of two classes of systems: conformal quantum matter and compressible quantum matter.

Fermi surfaces and gauge-gravity duality [PDF]

open access: yes, 2011
We give a unified overview of the zero temperature phases of compressible quantum matter: i.e. phases in which the expectation value of a globally conserved U(1) density, Q, varies smoothly as a function of parameters.

Zoo of quantum-topological phases of matter [PDF]

open access: yes, 2017
What are topological phases of matter? First, they are phases of matter at zero temperature. Second, they have a non-zero energy gap for the excitations above the ground state. Third, they are disordered liquids that seem have no feature.

Climate change drives habitat contraction of a nocturnal arboreal marsupial at its physiological limits

open access: yesEcosphere, Volume 11, Issue 10, October 2020., 2020
Abstract Increasing impacts of climatic change and anthropogenic disturbances on natural ecosystems are leading to population declines or extinctions of many species worldwide. In Australia, recent climatic change has caused population declines in some native fauna.
