The Bolzano-Weierstrass Theorem is the Jump of Weak K\"onig's Lemma [PDF]

, 2012
We classify the computational content of the Bolzano-Weierstrass Theorem and variants thereof in the Weihrauch lattice. For this purpose we first introduce the concept of a derivative or jump in this lattice and we show that it has some properties ...

Photodissociative Regulation of Star Formation in Metal-Free Pregalactic Clouds [PDF]

, 1999
We study the H2 photodissociation regions around OB stars in primordial gas clouds whose virial temperatures are between a few hundred and a few thousand Kelvin. In such small objects, a single O star can photodissociate a mass equal to that of the cloud

Coupling of Er3+ ions and Plasmonic Modes in Vertical Nanocavities for Spectral Broadening in Telecom Bands

Advanced Materials Technologies, EarlyView.
Left: Illustration of the glass & nanostructures system and the NIR emission at 1.5 µm, where the colored spheres represent the Er3+ ions within the doped glass. Right: Representation of the Stark splitting of the 4I13/2 and 4I15/2 manifolds of the Er3+, illustrating how the plasmonic modes facilitate the emission from the broader Stark manifold ...

Ethnicity and the surgical management of early invasive breast cancer in over 164 000 women

BJS (British Journal of Surgery), EarlyView., 2020
This large national study examined in detail the patterns in surgical management of early breast cancer in women of different ethnicities. Allowing for different patterns of age and stage at presentation, the surgical management of early breast cancer was similar in all women, regardless of ethnicity. All treated the same Background Limited information

A Nanoparticle‐Integrated Complete Manufacturing Pipeline of Chemically Engineered Exosomes

Advanced Science, EarlyView.
We report a novel manufacture technology of chemically engineered exosomes. The four steps of manufacturing, i.e., biogenesis, loading, isolation, and storage, are integrated by the use of a nanoparticle. The manufacture technology incorporates three innovative components, i.e., a new nano‐bio effect, a new composite nanoparticle, and a new isolation ...
