A dataset of hemoglobin blood value and photoplethysmography signal for machine learning-based non-invasive hemoglobin measurement

open access: yesData in Brief
Hemoglobin (Hb), a protein found within red blood cells, is responsible for transporting oxygen and carbon dioxide gasses. A low concentration of Hb indicates the existence of anemia.

A parton picture of de Sitter space during slow-roll inflation

open access: yes, 2009
It is well-known that expectation values in de Sitter space are afflicted by infra-red divergences. Long ago, Starobinsky proposed that infra-red effects in de Sitter space could be accommodated by evolving the long-wavelength part of the field according

Dynamical gluon mass generation and the IR sector of QCD

open access: yes, 2010
We review the Pinch Technique - Background Field Method (PT-BFM) framework for formulating and solving the Schwinger-Dyson equations of Yang-Mills theories.

On Resumming Inflationary Perturbations beyond One-loop

open access: yes, 2008
It is well known that the correlation functions of a scalar field in a quasi-de Sitter space exhibit at the loop level cumulative infra-red effects proportional to the total number of e-foldings of inflation.

Isolation and Reactivity of a Square‐Planar Trisamido Silane

open access: yesAngewandte Chemie International Edition, EarlyView.
We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...

A Dithio Vinylthio C2 Synthon Enabling Crystalline and Luminescent Sulfur‐Decorated Polymers

open access: yesAngewandte Chemie International Edition, EarlyView.
Transforming CaC2 into a modular C2 building block enables the synthesis of α,ω‐bis(vinylthio) monomer and its conversion into crystalline, sequence‐defined sulfur‐decorated polymers. Their dense thioether clustering induces nonconventional luminescence and provides structure–function control in a more‐sustainable polymer platform.
