N = 1 sigma models in AdS[subscript 4]
(Springer-Verlag, 2011-12)We study sigma models in AdS4 with global N = 1 supersymmetry and find that they differ significantly from their flat-space cousins — the target space is constrained to be a K¨ahler manifold with an exact K¨ahler form, ... -
N = 4 superconformal bootstrap of the K[subscript 3] CFT
(Springer Berlin Heidelberg, 2017-05)We study two-dimensional (4, 4) superconformal field theories of central charge c = 6, corresponding to nonlinear sigma models on K[subscript 3] surfaces, using the superconformal bootstrap. This is made possible through ... -
The N = 8 superconformal bootstrap in three dimensions
(Springer-Verlag, 2014-09)We analyze the constraints imposed by unitarity and crossing symmetry on the four-point function of the stress-tensor multiplet of N=8 superconformal field theories in three dimensions. We first derive the superconformal ... -
¹⁵N and ¹H Solid-State NMR Investigation of a Canonical Low-Barrier Hydrogen-Bond Compound: 1,8-Bis(dimethylamino)naphthalene
(American Chemical Society (ACS), 2017-06-29)Strong or low-barrier hydrogen bonds have often been proposed in proteins to explain enzyme catalysis and proton-transfer reactions. So far ¹H chemical shifts and scalar couplings have been used as the main NMR spectroscopic ... -
N Jettiness: An Inclusive Event Shape to Veto Jets
(American Physical Society, 2010-08)Jet vetoes are essential in many analyses at the LHC and Tevatron. Typical signals have a specific number of hard jets or leptons, while backgrounds have additional jets. Vetoing undesired jets efficiently discriminates ... -
An N Server Cutoff Multi-Priority Queue
(Massachusetts Institute of Technology, Operations Research Center, 1985-02)Consider a multi-priority, nonpreemptive, N-server Poisson arrival queueing system. Service times are negative exponential. In order to save available servers for higher priority customers, arriving customers of each lower ... -
An N Server Cutoff Priority Queue Where Customers Request a Random Number of Servers
(Massachusetts Institute of Technology, Operations Research Center, 1985-05)Consider a multi-priority, nonpreemptive, N-server Poisson arrival queueing system. The number of servers requested by an arrival has a known probability distribution. Service times are negative exponential. In order to ... -
(n,nʹ[gamma]) reactions in 6̳3̳,̳6̳5̳Cu and background in 0[nu] [beta] [beta] experiments
(Massachusetts Institute of Technology, 2008)Measurements of (n, xnʹ[gamma]) reactions in Cu are important for understanding neutroninduced background for certain underground double beta decay experiments. Neutroninduced gammas are a contribution to background for ... -

The N-end rule degradation pathway : substrate recognition and staged delivery to the CIpAP protease by the CIpS adaptor protein
(Massachusetts Institute of Technology, 2011)Regulated protein degradation is crucial in the regulation of many physiological processes as well as in protein quality control. In all organisms, ranging from bacteria to mammals, ATP-dependent proteases carry out regulated ... -
N-Face GaN/AlGaN HEMTs Fabricated Through Layer Transfer Technology
(Institute of Electrical and Electronics Engineers, 2009-01)We present a new method to fabricate N-face GaN/AlGaN high electron mobility transistors (HEMTs). These devices are extremely promising for ultrahigh frequency applications where low contact resistances and excellent carrier ... -
(N-heterocyclic-carbene)Copper(I)-catalyzed carbon-carbon bond formation using carbon dioxide
(Massachusetts Institute of Technology, 2007)This thesis presents work towards the development of a new catalytic C-C bond forming reaction. Alkynes and olefins insert into [(IPr)CuH]2 (IPr = N,N-bis-(2,6-diisopropylphenyl)-1,3-imidazol-2-ylidene) to give copper vinyl ... -
N-jettiness subtractions for gg → H at subleading power
(American Physical Society, 2018-01)N-jettiness subtractions provide a general approach for performing fully-differential next-to-next-to-leading order (NNLO) calculations. Since they are based on the physical resolution variable N-jettiness, T[subscript N], ... -
N-Linked Glycans Are Assembled on Highly Reduced Dolichol Phosphate Carriers in the Hyperthermophilic Archaea Pyrococcus furiosus
(Public Library of Science, 2015-06)In all three domains of life, N-glycosylation begins with the assembly of glycans on phosphorylated polyisoprenoid carriers. Like eukaryotes, archaea also utilize phosphorylated dolichol for this role, yet whereas the ... -
N-methyl d-Aspartate Channels Link Ammonia and Epithelial Cell Death Mechanisms in Helicobacter pylori Infection
(Elsevier BV, 2011-09)Background & Aims: Helicobacter pylori infection is a risk factor for gastric cancer. Ammonia/ammonium (A/A) is a cytotoxin generated by H pylori that kills gastric epithelial cells. We investigated whether A/A cytotoxicity ... -
N-polar AlN buffer growth by MOVPE for transistor applications
(Japan Society of Applied Physics, 2018)We present the electrical characterization of N-polar AlN layers grown by metal-organic vapor phase epitaxy and the demonstration of N-polar AlN-channel metal-semiconductor field-effect transistors (MESFETs). A high ... -
n-relative categories: a model for the homotopy theory of n-fold homotopy theories
(International Press of Boston, Inc., 2013-12)We introduce, for every integer n ≥ 1, the notion of an n-relative category and show that the category of the small n-relative categories is a model for the homotopy theory of n-fold homotopy theories, i.e., homotopy ... -
An N-stage Cascade of Phosphorylation Cycles as an Insulation Device for Synthetic Biological Circuits
(2016-03-27)Single phosphorylation cycles have been found to have insulation device abilities, that is, they attenuate the effect of retroactivity applied by downstream systems and hence facilitate modular design in synthetic ... -
