A Caratheodory theorem for the bidisk via Hilbert space methods [PDF]
arXiv, 2010 If $\ph$ is an analytic function bounded by 1 on the bidisk $\D^2$ and $\tau\in\tb$ is a point at which $\ph$ has an angular gradient $\nabla\ph(\tau)$ then $\nabla\ph(\la) \to \nabla\ph(\tau)$ as $\la\to\tau$ nontangentially in $\D^2$. This is an analog for the bidisk of a classical theorem of Carath\'eodory for the disk.

pH Dependent surface enhanced Raman study of Phe + Ag Complex and DFT calculations for spectral analysis [PDF]
, 2006 Surface enhanced Raman spectra of Phenylalanine (Phe) in Ag colloidal solution have been recorded for Phe solutions of different pH. Spectral line-shape analyses of the enhanced modes, at 1005, 1380 and 1582 cm-1, between pH 4.5 and 10.5, have been carried out. The variation of spectral line-width with pH reveals two possible mechanisms in solution: (i)

Persistent-Homology-based Machine Learning and its Applications -- A Survey [PDF]
arXiv, 2018 A suitable feature representation that can both preserve the data intrinsic information and reduce data complexity and dimensionality is key to the performance of machine learning models. Deeply rooted in algebraic topology, persistent homology (PH) provides a delicate balance between data simplification and intrinsic structure characterization, and ...

Ability of Cyanobacteria and Arthrobacter Species to Remove Gold Ions from Solution [PDF]
arXiv, 2012 The biosorption of Au(III) - Spirulina platensis and Au(III) - Arthrobacter species (Arthrobacter globiformis and Arthrobacter oxidas) were studied at simultaneous application of dialysis and atomic absorption analysis. Also biosorption of Au(III) - Spirulina platensis at various pH were discussed.

A Compressed Particle-Hole Symmetric Pfaffian State for $ν= 5/2$ Quantum Hall Effect [PDF]
arXiv, 2020 A recent thermal Hall conductance experiment [Banerjee et al., Nature {\bf559}, 205 (2018)] for $\nu = 5/2$ fractional quantum Hall system appears to rule out both the Pfaffian and anti-Pfaffian and be in favor of the PH-Pfaffian topological order, while the existing numerical results without disorder have shown otherwise.
