Topology and its Applications, 2021 We consider flows (X,T ), given by actions (t, x) → tx, on a compact metric space X with a discrete T as an acting group. We study a new class of flows the Strongly Rigid (SR) flows, that are properly contained in the class of distal (D) flows and ...

Analytical approach to continuous and intermittent bottleneck flows. [PDF]
Physical Review Letters, 2006 We propose a many-particle-inspired theory for granular outflows from a hopper and for the escape dynamics through a bottleneck based on a continuity equation in polar coordinates.

Journal of Glaciology, 2023 The dynamics of the Greenland Ice Sheet are affected by surface meltwater reaching the base of the ice, altering ice contact with the bedrock. Lack of understanding of this evolution hampers the ability to predict the effects of increasing temperatures ...

Rational antibody design for undruggable targets using kinetically controlled biomolecular probes
Science Advances, 2021 This newly developed biological probes/proteomics method yields functional antibodies targeting previously undruggable targets. Several important drug targets, e.g., ion channels and G protein–coupled receptors, are extremely difficult to approach with ...

The Physics of Fluids, 2023 A transitional flow regime is known to induce complex flow structures upon aerodynamic geometries such as airfoils, and the dynamics of laminar separation bubbles (LSBs) pose a relevant research field.

Non-autonomous scalar linear-dissipative and purely dissipative parabolic PDEs over a compact base flow [PDF]
, 2021 In this paper a family of non-autonomous scalar parabolic PDEs over a general compact and connected flow is considered. The existence or not of a neighbourhood of zero where the problems are linear has an influence on the methods used and on the dynamics

McMullen polynomials and Lipschitz flows for free-by-cyclic groups [PDF]
, 2013 Consider a group G and an epimorphism u_0:G\to\Z inducing a splitting of G as a semidirect product ker(u_0)\rtimes_\varphi\Z with ker(u_0) a finitely generated free group and \varphi\in Out(ker(u_0)) representable by an expanding irreducible train track ...

The Cryosphere, 2022 . Basal ice-shelf melting is the key driver of Antarctica's increasing sea-level contribution. In diminishing the buttressing force of the ice shelves that fringe the ice sheet, the melting increases the ice discharge into the ocean. Here we contrast the

Dynamics and rheology under continuous shear flow studied by x-ray photon correlation spectroscopy [PDF]
, 2010 X-ray photon correlation spectroscopy (XPCS) has emerged as a unique technique allowing the measurement of dynamics of materials on mesoscopic lengthscales.

Fracture-induced softening for large-scale ice dynamics
, 2012 Floating ice shelves can exert a retentive and hence stabilizing force onto the inland ice sheet of Antarctica. However, this effect has been observed to diminish by the dynamic effects of fracture processes within the protective ice shelves, leading to ...
