Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

A Schematic for Focusing on Youth in Investigations of Community Design and Physical Activity [PDF]

open access: yes
This paper provides a first step to address special considerations for youth in a relatively new area of physical activity research. After reviewing the urgent need for novel approaches to increasing physical activity, the growing interest in the effects

Fermionic SPT phases in higher dimensions and bosonization

open access: yesJournal of High Energy Physics, 2017
We discuss bosonization and Fermionic Short-Range-Entangled (FSRE) phases of matter in one, two, and three spatial dimensions, emphasizing the physical meaning of the cohomological parameters which label such phases and the connection with higher-form ...

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

open access: yesFEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Spatiotemporal analysis of Indian megacities

open access: yes, 2008
Urbanization is arguably the most dramatic form of highly irreversible land transformation. While urbanization is a worldwide phenomenon, it is exceptionally dynamic in India, where unprecedented urban growth rates have occurred over the last 30 years ...

Toward a mathematical approach of spatial permeability (Kyrillos's Model)

open access: yesComputational Urban Science
Spatial permeability is a distinctive characteristic of urban form. However, a definitive method for measuring it remains a challenge. This study aims to investigate factors affecting permeability within urban systems, with a focus on incorporating a ...

Thermodynamic and Differential Entropy under a Change of Variables

open access: yesEntropy, 2010
The differential Shannon entropy of information theory can change under a change of variables (coordinates), but the thermodynamic entropy of a physical system must be invariant under such a change.

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

open access: yesFEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

The Form-based Development Plan: bridging the gap between theory and practice in urban morphology

open access: yes, 2008
The format of local development plans and site-specific guidance tends to be based on land-use allocations rather than physical form. This approach has serious limitations, especially when dealing with urban design issues.

Pulse generation scheme for flying electromagnetic doughnuts

open access: yes, 2018
Transverse electromagnetic plane waves are fundamental solutions of Maxwells equations. It is less known that a radically different type of solutions has been described theoretically, but has never been realized experimentally, that exist only in the ...
