Holography of dislocations and ring defects in Einstein–Gauss–Bonnet AdS gravity

European Physical Journal C: Particles and Fields
We study torsional topological defects in Einstein–Gauss–Bonnet gravity in ( $$4+1$$ 4 + 1 )-dimensional anti-de Sitter spacetime. In the holographic interpretation, these correspond to crystalline dislocation defects associated with the discrete lattice

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Towards the CdS/SnSe solar cell optimization: Understanding the transport mechanisms

Results in Physics
In this work, numerical simulation results on SnSe solar cells are presented. The influence of loss mechanisms such as radiative recombination, SnSe bulk recombination, and CdS/SnSe interface recombination on the device is studied in detail under and ...

Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy

FEBS Letters, EarlyView.
The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.

How to get an interacting conformal line defect for free theories

Journal of High Energy Physics
We argue that interacting conformal line defects in free quantum field theories can exist, provided that inversion symmetry is broken. Important for our demonstration is the existence of a special cross ratio for bulk-defect-defect three point functions ...

Premelting at defects within bulk colloidal crystals

, 2006
We observe premelting at grain boundaries and dislocations within bulk colloidal crystals using video microscopy. The crystals are 3D thermally responsive microgel colloidal structures.

Comparing the paths of Hedgehog release in artificial and natural settings

FEBS Letters, EarlyView.
Hh morphogens require solubilization factors to overcome their tight association with the plasma membrane and signal to distant cells, but the precise functions of these factors are controversial. Here, we use published in vivo observations as the most relevant evidence to test their suggested functions and discuss contradictions and gaps between in ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Plasticity of Bi2Te3-family thermoelectric crystals

Nature Communications
The exceptional plasticity discovered most recently in defective Bi2Te3 bulk crystal inspires the great interest on investigating the plasticity of other Bi2Te3-family bulk crystals. In this work, Bi2Se3, Sb2Te3, and their solid solutions with Bi2Te3 are
