Aria: a fast and practical deterministic OLTP database
(VLDB Endowment, 2020)© 2020, VLDB Endowment. Deterministic databases are able to efficiently run transactions across different replicas without coordination. However, existing state-of-the-art deterministic databases require that transaction ... -
Arid Coastal Carbonates and the Phanerozoic Record of Carbonate Chemistry

Aristolochic Acids as Persistent Soil Pollutants: Determination of Risk for Human Exposure and Nephropathy from Plant Uptake
(American Chemical Society (ACS), 2018-10-05)Exposure to aristolochic acids (AAs) from Aristolochia plants is one of the major global causes of nephropathy, including Balkan endemic nephropathy (BEN); renal failure; and urothelial cancer. The high incidence of BEN ... -
Arithmetic diagonal cycles on unitary Shimura varieties
(Wiley, 2020)<jats:p>We define variants of PEL type of the Shimura varieties that appear in the context of the arithmetic Gan–Gross–Prasad (AGGP) conjecture. We formulate for them a version of the AGGP conjecture. We also construct ... -

Arithmetic expression construction
(2020-12-01)When can n given numbers be combined using arithmetic operators from a given subset of {+,−,×,÷} to obtain a given target number? We study three variations of this problem of Arithmetic Expression Construction: when the ... -
Arm-length stabilisation for interferometric gravitational-wave detectors using frequency-doubled auxiliary lasers
(Optical Society of America, 2011-12)Residual motion of the arm cavity mirrors is expected to prove one of the principal impediments to systematic lock acquisition in advanced gravitational-wave interferometers. We present a technique which overcomes this ... -
Arnold‐Thom Gradient Conjecture for the Arrival Time
(Wiley, 2019-03-13)We prove conjectures of René Thom and Vladimir Arnold for C 2 solutions to the degenerate elliptic equation that is the level set equation for motion by mean curvature. We believe these results are the first instances of ... -
Aromatic and basic residues within the EVH1 domain of VASP specify its interaction with proline-rich ligands
(Elsevier, 1999-07)Short contiguous peptides harboring proline-rich motifs are frequently involved in protein–protein interactions, such as associations with Src homology 3 (SH3) and WW domains. Although patches of aromatic residues present ... -
Aromatic spectral editing techniques for magic-angle-spinning solid-state NMR spectroscopy of uniformly 13C-labeled proteins
(Elsevier, 2015-09)The four aromatic amino acids in proteins, namely histidine, phenylalanine, tyrosine, and tryptophan, have strongly overlapping ¹³C chemical shift ranges between 100 and 160 ppm, and have so far been largely neglected in ... -
Aromatics and Cyclic Molecules in Molecular Clouds: A New Dimension of Interstellar Organic Chemistry
(American Chemical Society (ACS), 2021-03)Astrochemistry lies at the nexus of astronomy, chemistry, and molecular physics. On the basis of precise laboratory data, a rich collection of more than 200 familiar and exotic molecules have been identified in the ... -

AROUND 200 NEW X-RAY BINARY IDs FROM 13 YR OF CHANDRA OBSERVATIONS OF THE M31 CENTER
(IOP Publishing, 2013-12)We have created 0.3-10 keV, 13 yr, unabsorbed luminosity lightcurves for 528 X-ray sources in the central 20' of M31. We have 174 Chandra observations spaced at ~1 month intervals due to our transient monitoring program, ... -
Around quantum ergodicity
(Springer International Publishing, 2021-06-24)Abstract We discuss Shnirelman’s Quantum Ergodicity Theorem, giving an outline of a proof and an overview of some of the recent developments in mathematical Quantum Chaos. -
Arp2/3 Is a Negative Regulator of Growth Cone Translocation
(Elsevier, 2004-07)Arp2/3 is an actin binding complex that is enriched in the peripheral lamellipodia of fibroblasts, where it forms a network of short, branched actin filaments, generating the protrusive force that extends lamellipodia and ... -
An Arp2/3 Nucleated F-Actin Shell Fragments Nuclear Membranes at Nuclear Envelope Breakdown in Starfish Oocytes
(Elsevier, 2014-06)Animal cells disassemble and reassemble their nuclear envelopes (NEs) upon each division. Nuclear envelope breakdown (NEBD) serves as a major regulatory mechanism by which mixing of cytoplasmic and nuclear compartments ... -
ARQ with Cumulative Feedback to Compensate for Burst Errors
(IEEE, 2018-12)© 2018 IEEE. We propose a cumulative feedback-based ARQ (CF ARQ) protocol for a sliding window of size 2 over packet erasure channels with unreliable feedback. We exploit a matrix signal-flow graph approach to analyze ... -

Arrangements of equal minors in the positive Grassmannian
(Elsevier BV, 2016-03)We discuss arrangements of equal minors of totally positive matrices. More precisely, we investigate the structure of equalities and inequalities between the minors. We show that arrangements of equal minors of largest ...
