Signatures and flatness.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1993
Let \(Y\subset\mathbb{R}^ n\) be a codimension one analytic set, and fix a signature \(\sigma\) on \(\mathbb{R}^ n\backslash Y\) \((\sigma\) associates a \(\text{sign}+1\) or \(-1\) to each connected component of \(\mathbb{R}^ n\backslash Y)\). The signature \(\sigma\) is admissible at \(x\in Y\) when the germ \(\sigma_ x\) is induced by a germ of ...

The symmetric signature

open access: yes, 2016
We define two related invariants for a $d$-dimensional local ring $(R,\mathfrak{m},k)$ called syzygy and differential symmetric signature by looking at the maximal free splitting of reflexive symmetric powers of two modules: the top dimensional syzygy ...

Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

An Evaluation of Link Neighborhood Lexical Signatures to Rediscover Missing Web Pages [PDF]

open access: yes, 2011
For discovering the new URI of a missing web page, lexical signatures, which consist of a small number of words chosen to represent the "aboutness" of a page, have been previously proposed. However, prior methods relied on computing the lexical signature

Why is Spacetime Lorentzian?

open access: yes, 1993
We expand on the idea that spacetime signature should be treated as a dynamical degree of freedom in quantum field theory. It has been argued that the probability distribution for signature, induced by massless free fields, is peaked at the Lorentzian ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Polarizing the Neuron through Sustained Co-expression of Alternatively Spliced Isoforms

open access: yesCell Reports, 2016
Alternative splicing (AS) is an important source of proteome diversity in eukaryotes. However, how this affects protein repertoires at a single-cell level remains an open question.

Identification of Novel Prognostic Risk Signatures of Soft Tissue Sarcoma Based on Ferroptosis-Related Genes

open access: yesFrontiers in Oncology, 2021
BackgroundThe role of ferroptosis in tumorigenesis has been confirmed in previous studies. However, the comprehensive analysis of ferroptosis-related gene (FRG) to study the role of FRG in soft tissue sarcoma (STS) is lacking.MethodsRNA sequencing ...

Various L2-signatures and a topological L2-signature theorem

open access: yes, 2007
For a normal covering over a closed oriented topological manifold we give a proof of the L2-signature theorem with twisted coefficients, using Lipschitz structures and the Lipschitz signature operator introduced by Teleman.
