The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

A slender-wing theory in potential flow

open access: yes, 2005
Consider uniform, steady potential flow past a slender wing. By considering a horseshoe vortex in the limit as γ/Us → ∞, where γ is the circulation, U is the uniform stream velocity and s is the span, a model representing a vortex sheet is obtained from ...

A TALE OF ELLIPSOIDS IN POTENTIAL THEORY [PDF]

open access: yes, 2013
Ellipsoids possess several beautiful properties associ- ated with classical potential theory. Some of them are well known, and some have been forgotten. In this article we hope to bring a few of the \lost" pieces of classical mathematics back to the lime-

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Graph-Theory-Based Molecular Fragmentation for Efficient and Accurate Potential Surface Calculations in Multiple Dimensions

open access: yes, 2021
We present a multitopology molecular fragmentation approach, based on graph theory, to calculate multidimensional potential energy surfaces in agreement with post-Hartree–Fock levels of theory but at the density functional theory cost.

Harnack inequalities for hypoelliptic evolution operators: geometric issues and applications

open access: yesBruno Pini Mathematical Analysis Seminar, 2012
We consider linear second order Partial Differential Equations in the form of "sum of squares of Hörmander vector fields plus a drift term" on a given domain.

A finite element method for exterior interface problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1980
A procedure is given for the approximate solution of a class of two-dimensional diffraction problems. Here the usual inner boundary conditions are replaced by an inner region together with interface conditions.

A novel technique for the calculation of post-stall aerodynamic coefficients for S809 airfoil [PDF]

open access: yesFME Transactions, 2020
In the autumn of 2000, the National Renewable Energy Laboratory (NREL) organised a 'blind comparison', in which wind turbine research centres worldwide were asked to provide stationary aerodynamic loads for the wind turbine Phase VI and aerodynamic ...

Sense of Place, Fast and Slow: The Potential Contributions of Affordance Theory to Sense of Place

open access: yesFrontiers in Psychology, 2017
Over the past 40 years, the sense of place concept has been well-established across a range of applications and settings; however, most theoretical developments have “privileged the slow.” Evidence suggests that place attachments and place meanings are ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
