The Khovanov homology of 3-strand pretzels, revisited [article]

Andrew Manion
2013 arXiv   pre-print
We compute the reduced Khovanov homology of 3-stranded pretzel links. The coefficients are the integers with the "even" sign assignment.  ...  In particular, we show that the only homologically thin, non-quasi-alternating 3-stranded pretzels are P(-p,p,r) with p an odd integer and r greater than or equal to p (these were shown to be homologically  ...  Order the crossings so that those in the p-strand come first, then those in the q-strand, then those in the r-strand.  ...

Strands algebras and Ozsváth-Szabó's Kauffman-states functor [article]

Andrew Manion, Marco Marengon, Michael Willis
2019 arXiv   pre-print
We also show how Ozsv\'ath-Szab\'o's gradings on B(n,k,S) arise naturally from the general framework of group-valued gradings on strands algebras.  ...  We define new differential graded algebras A(n,k,S) in the framework of Lipshitz-Ozsv\'ath-Thurston's and Zarev's strands algebras from bordered Floer homology.  ...  strand in s ′ .  ...

Extreme Scaling of Supercomputing with Stranded Power: Costs and Capabilities [article]

Fan Yang, Andrew A. Chien
2016 arXiv   pre-print
We proposes to exploit stranded power, renewable energy that has no value to the power grid, for scaling supercomputers, Zero-Carbon Cloud (ZCCloud), and showing that stranded power can be employed effectively  ...  We build on those results with a new analysis of stranded power, characterizing temporal, geographic, and interval properties.  ...  ZCCloud uses stranded power as its only power source, and thus only operates when stranded power is available and shut down when there is no stranded power.  ...

A 1,3-phenyl-linked hydantoin oligomer scaffold as a β-strand mimetic

Andrew G. Jamieson, David Russell, Andrew D. Hamilton
2012 Chemical Communications  
All experiments were carried out under an atmosphere of nitrogen, using anhydrous solvents, unless otherwise stated. All chemicals were purchased from Sigma-Aldrich and used as received. Analytical thin layer chromatography was carried out on Merck Kieselgel 60 F 254 plates with visualisation by ultraviolet light. Flash column chromatography was performed using Merck Kieselgel 60 (230-400 mesh). Infra-red spectra were recorded on a Perkin Elmer System 100 with a Universal ATR attachment

NMR spectra were recorded on Brucker DPX 300 ( 1 H, 300 MHz; 13 C, 75 MHz), Brucker DPX 400 ( '1H, 400 MHz; 13 C, 100 MHz) or Brucker Avance III 500 ( 1 H, 500 MHz; 13 C, 125 MHz) spectrometers as indicated. NMR chemical shifts (δ) are quoted in ppm relative to the residual non-deuterated solvent peak of chloroform ( 1 H δ 7.26, 13 C δ 77.0) and coupling constants (J) are quoted to the nearest 0.1 Hertz (Hz). Spectral data is reported as follows: chemical shift, integration, multiplicity (s, singlet; d, doublet; t, triplet; m, multiplet; or as a combination of these), coupling constant(s) and assignment. 1 H assignment is supported by COSY spectra where necessary. 13 C assignment is supported by APT and HSQC spectra correlations where necessary. Melting points were recorded on a Reichert Köfler micro heating stage melting point apparatus and are uncorrected. Highresolution mass spectra were recorded on a Kratos Concept 1H spectrometer using peak matching to stable reference.

Data Centers as Dispatchable Loads to Harness Stranded Power [article]

Kibaek Kim, Fan Yang, Victor M. Zavala, Andrew A. Chien
2016 arXiv   pre-print
Our analysis reveals that significant spillage and stranded power will be observed in power grids as wind power levels are increased.  ...  In contrast, optimally placing data centers that are dispatchable (with flexible loads) provides system-wide flexibility, reduces stranded power, and improves efficiency.  ...  Fan Yang and Andrew A. Chien are with the Department of Computer Science at the University of Chicago. Victor M.  ...

2–strand twisting and knots with identical quantum knot homologies

2014 Geometry and Topology  
Given a knot, we ask how its Khovanov and Khovanov-Rozansky homologies change under the operation of introducing twists in a pair of strands.  ...  One such ad hoc construction is based on pure Brunnian braids (pure braids that become equivalent to a trivial braid when any strand is removed).  ...  Introduction and results In this paper we consider sl.n/ Khovanov-Rozansky homology [6] (Khovanov homology appears as n D 2) under the operation of adding twists in a pair of strands.  ...

Multiple classes of bactericidal antibiotics cause DNA double strand breaks in Staphylococcus aureus [article]
