DEN Open, Volume 6, Issue 1, April 2026.ABSTRACT Objective Gel‐immersion endoscopic injection sclerotherapy (GI‐EIS) addresses the technical challenges in intravariceal injection for esophageal varices (EVs). However, gel accumulation may obscure the variceal morphology. Thus, we developed GI‐EIS under texture and color enhancement imaging (TXI) and evaluated its effectiveness.

Oikos, Volume 2026, Issue 2, February 2026.Urbanisation is a major driver of environmental change, reshaping ecological and evolutionary processes. Urban‐driven phenotypic differences are increasingly documented, but the underlying role of selection is still understudied. One pattern is the consistent reduction of carotenoid‐based plumage pigmentation in city birds.

Kauffman Knot Invariant from SO(N) or Sp(N) Chern-Simons theory and the Potts Model
, 2010 The expectation value of Wilson loop operators in three-dimensional SO(N) Chern-Simons gauge theory gives a known knot invariant: the Kauffman polynomial. Here this result is derived, at the first order, via a simple variational method.

Sex matters: European urban birds flee approaching women sooner than approaching men
People and Nature, Volume 8, Issue 2, Page 316-326, February 2026.Abstract Flight initiation distance (FID) is a metric often used to study an individual's perceptions of risk when facing a predatory threat. Longer FID indicates lower risk‐taking, while shorter FID identifies bolder individuals who tolerate greater risk.

Chromatic roots are dense in the whole complex plane [PDF]
, 2004 I show that the zeros of the chromatic polynomials P-G(q) for the generalized theta graphs Theta((s.p)) are taken together, dense in the whole complex plane with the possible exception of the disc \q - l\ < l.

Potts model on recursive lattices: some new exact results
, 2012 We compute the partition function of the Potts model with arbitrary values of $q$ and temperature on some strip lattices. We consider strips of width $L_y=2$, for three different lattices: square, diced and `shortest-path' (to be defined in the text). We

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 272-290, February 2026.Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

(3+1)-dimensional topological phases and self-dual quantum geometries encoded on Heegard surfaces
, 2017 We apply the recently suggested strategy to lift state spaces and operators for (2+1)-dimensional topological quantum field theories to state spaces and operators for a (3+1)-dimensional TQFT with defects.
