Dyck Words and Multi-Quark Primitive Amplitudes
, 2013 I study group theory (Kleiss-Kuijf) relations between purely multi-quark primitive amplitudes at tree level, and prove that they reduce the number of independent primitives to (n-2)!/(n/2)!, where n is the number of quarks plus antiquarks, in the case ...

Affinity Peptides With pH Sensitivity for the Enrichment of CD38+ Cells
Biotechnology and Bioengineering, EarlyView.ABSTRACT The selective enrichment of cell populations based on surface markers is critical for the advancement of gene and cell therapies. Current antibody‐based cell isolation methods, such as fluorescence‐ and magnetic‐activated cell sorting (FACS and MACS), offer high specificity but are limited by scalability, cost, and potential adverse effects on

On Billaud words and their companions
, 2021 The Billaud Conjecture, which has been open since 1993, is a fundamental problem on finite words w and their heirs, i.e., the words obtained by deleting every occurrence of a given letter from w. It posits that every morphically primitive word, i.e.

Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Counting border and primitive words with a fixed weight
, 2004 A word w is primitive if it is not a proper power of another word, and w is unbordered if it has no prefix that is also a suffix of w. We study the number of primitive and unbordered words w with a fixed weight, that is, words for which the Parikh vector

Biological Reviews, EarlyView.ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance
Business Strategy and the Environment, EarlyView.ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

AI + Drawing Enhances the Efficiency of Human Anatomy Education
Clinical Anatomy, EarlyView.ABSTRACT Human anatomy is a fundamental core course in medical education, and its teaching effectiveness directly influences students' understanding and application of medical knowledge. However, traditional anatomy instruction often faces challenges such as limited teaching resources and the high cognitive difficulty students experience.
