Feynman integral reduction using syzygy-constrained symbolic reduction rules
We present a new algorithm for integration-by-parts (IBP) reduction of Feynman integrals with high powers of numerators or propagators, a demanding computational step in evaluating multi-loop scattering amplitudes.

Dilaton and massive hadrons in a conformal phase
As the number of fermion fields is increased, gauge theories are expected to undergo a transition from a QCD-like phase, characterised by confinement and chiral symmetry breaking, to a conformal phase, where the theory becomes scale-invariant at large ...

Capacity and limitations of US wild meat donation programmes
Abstract Historically, sharing of wild harvests to facilitate food security followed concepts of kin selection and reciprocal altruism. However, cultural shifts have reduced access to foods for some populations in modern times. Cultural altruism through sustainably harvested wild meat donation programmes (WDPs) can reduce food and nutritional ...

Tensor reduction for Feynman integrals with Lorentz and spinor indices
We present an efficient graphical approach to construct projectors for the tensor reduction of multi-loop Feynman integrals with both Lorentz and spinor indices in D dimensions.

This article demonstrates that assimilating machine‐learning‐derived surface nitrate can improve five‐day phytoplankton forecast substantially within the Met Office operational system for the Northwest European Shelf. We explain the reasons behind this improvement and propose that an online system where machine learning and data assimilation are cycled

N=1 Euler Anomaly from RG-dependent metric-Background
We consider N = 1supersymmetric gauge theories in the conformal window. By applying a suitable matter superfield- and Weyl-transformation the renormalisation group running of the theory is absorbed into the metric.

Abstract Statistical hypothesis testing (SHT) is widely employed across numerous scientific disciplines, and a clear understanding of its underlying logic is essential for the broader scientific community. Here, drawing upon both epistemological and statistical perspectives, we aim to clarify—primarily for educational purposes—the logical relationship ...

Advances in cholesterol and lipoproteins detection for healthcare: A review
Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most

Little Higgs, Non-standard Higgs, No Higgs and All That
We give a brief review of recent developments in non-supersymmetric models for electroweak symmetry breaking, including little Higgs, composite Higgs and Higgsless theories. The new ideas such as extra dimensions, AdS/CFT correspondence, dimension-deconstruction, and collective symmetry breaking provide us new tools to construct new models.
