Unrolling of Syngonium podophyllum: Functional Anatomy, Morphology and Modelling of Its Peltate Leaves

Advanced Biology, EarlyView.
The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.

Heavy quark fragmentation in e + e − collisions to NNLO+NNLL accuracy in perturbative QCD

Journal of High Energy Physics
Fragmentation of heavy quarks into heavy-flavoured hadrons receives both perturbative and non-perturbative contributions. We consider perturbative QCD corrections to heavy quark production in e + e − collisions to next-to-next-to-leading order accuracy ...

NLO QCD and EW corrections to vector-boson scattering into W+W − at the LHC

Journal of High Energy Physics, 2022
We present the full next-to-leading-order electroweak and QCD corrections to vector-boson scattering into a pair of off-shell opposite-sign W bosons decaying into leptons of different flavour at the LHC.

Engineering the Link: From Genome Interaction Maps to Functional Insight

Advanced Biology, EarlyView.
Advances in chromosome conformation capture have revealed the genome's 3D organization, yet its causal impact on gene regulation remains elusive. This review highlights emerging genome‐engineering tools ‐ zinc fingers, TALEs, and CRISPR‐Cas9 ‐ that enable targeted manipulation of chromatin loops to dissect structure–function relationships. It discusses

The transition temperature of the dilute interacting Bose gas for $N$ internal degrees of freedom

, 1999
We calculate explicitly the variation $\delta T_c$ of the Bose-Einstein condensation temperature $T_c$ induced by weak repulsive two-body interactions to leading order in the interaction strength.

Sampling NNLO QCD phase space with normalizing flows

Journal of High Energy Physics
We showcase the application of neural importance sampling for the evaluation of NNLO QCD scattering cross sections. We consider Normalizing Flows in the form of discrete Coupling Layers and time continuous flows for the integration of the various cross ...

Feynman integrals from positivity constraints

Journal of High Energy Physics, 2023
We explore inequality constraints as a new tool for numerically evaluating Feynman integrals. A convergent Feynman integral is non-negative if the integrand is non-negative in either loop momentum space or Feynman parameter space.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

The colourful antenna subtraction method

Journal of High Energy Physics
We present a general subtraction scheme for NNLO calculations in massless QCD: the colourful antenna subtraction method. It is a reformulation of the antenna subtraction approach designed to address some of the limitations of the traditional framework ...
