Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

A covariantisation of M5-brane action in dual formulation
Journal of High Energy Physics, 2018 We construct a manifestly diffeomorphic M5-brane action in dual formulation coupled to an eleven-dimensional supergravity target space. The covariantisation is carried out by using (generalised) PST technique with 5 auxiliary scalar fields, which are ...

Reflections for postgraduate students on writing an action research thesis
, 2017 The prospect of conducting action research as part of formal academic study can seem quite daunting for many. The academy, often dominated by a positivist approach, does not always appreciate the value and quality of research that is qualitative, action ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein
FEBS Letters, EarlyView.Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma
FEBS Letters, EarlyView.Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

On the n-Dimensional Porous Medium Diffusion Equation and Global Actions of the Symmetry Group
Symmetry, Integrability and Geometry: Methods and Applications, 2013 By restricting to a special class of smooth functions, the local action of the symmetry group is globalized. This special class of functions is constructed using parabolic induction.

Low-energy effective action in 5D,N=2 supersymmetric gauge theory
Nuclear Physics B, 2019 We construct N=2 supersymmetric low-energy effective action of 5D,N=2 supersymmetric Yang–Mills (SYM) theory in 5D,N=1 harmonic superspace. It is obtained as a hypermultiplet completion of the leading WlnW-term in the N=1 SYM low-energy effective action

Metastatic niche shaped by host factors influences disseminated cancer cell fate
FEBS Letters, EarlyView.Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Arches technology: technical brief [PDF]
, 2015 Arches are a common feature in houses today. It is a technology which has been in use for hundreds of years and has withstood the test of time as evidenced by the numerous arches seen in ancient buildings and old houses in Sri Lanka.
