Scalar quasinormal modes, Lyapunov exponents and radii of null geodesics of rotating regular black holes

European Physical Journal C: Particles and Fields
The quasinormal modes of massless scalar field in rotating Bardeen and Hayward regular black holes are studied. The fundamental quasinormal modes and $$n=1$$ n = 1 first overtone quasinormal modes are calculated with the matrix method.

Van der Waals gap tunning the excitons in 2D materials

Nano Research
The emerging two-dimensional (2D) materials exhibit strong exciton effects with rich exciton types, dominating their optical and optoelectronic properties.

Market Structure with Interacting Consumers [PDF]

Review of Behavioral Economics, 2017
Economic theory has developed a typology of markets which depends upon the number of firms which are present. Much of the literature, however, is set in the context of a given market structure, with the consequences of the structure being explored. Considerably less attention is paid to the process by which any particular structure emerges.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Revealing the mystery of the double charm tetraquark in pp collision

European Physical Journal C: Particles and Fields
A novel approach is proposed to probe the nature of the double charm tetraquark through the prompt production asymmetry between $$T_{\bar{c}\bar{c}}^-$$ T c ¯ c ¯ - and $$T_{cc}^+$$ T cc + in pp collisions.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The contacts between two-dimensional materials and metal electrodes

Nano Research
The advent of two-dimensional (2D) materials has ushered in a new era for electronic and optoelectronic devices. However, their atomic-scale thickness presents a fundamental contact interface challenge: the formation of a Schottky barrier at the 2D ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Encrypted metasurfaces with inherent asymmetric-like digitized keys under decoupled near-field parameters

Communications Physics
The modulation of the light field by metasurfaces in near-field remains constrained by the coupling of cross-polarization components. This limits the storage space for ciphertexts with orthogonal polarization states.

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

FEBS 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.
