N = 1 sigma models in AdS[subscript 4]
(SpringerVerlag, 201112)We study sigma models in AdS4 with global N = 1 supersymmetry and find that they differ significantly from their flatspace 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, 201705)We study twodimensional (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
(SpringerVerlag, 201409)We analyze the constraints imposed by unitarity and crossing symmetry on the fourpoint function of the stresstensor multiplet of N=8 superconformal field theories in three dimensions. We first derive the superconformal ... 
¹⁵N and ¹H SolidState NMR Investigation of a Canonical LowBarrier HydrogenBond Compound: 1,8Bis(dimethylamino)naphthalene
(American Chemical Society (ACS), 20170629)Strong or lowbarrier hydrogen bonds have often been proposed in proteins to explain enzyme catalysis and protontransfer 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, 201008)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 →π* Interaction in the Bound Substrate of Aspartic Proteases Replicates the Oxyanion Hole
(American Chemical Society (ACS), 201902)Aspartic proteases regulate many biological processes and are prominent targets for therapeutic intervention. Structural studies have captured intermediates along the reaction pathway, including the Michaelis complex and ... 
n →π* Interactions Modulate the Properties of Cysteine Residues and Disulfide Bonds in Proteins
(American Chemical Society (ACS), 201812)Noncovalent interactions are ubiquitous in biology, taking on roles that include stabilizing the conformation of and assembling biomolecules, and providing an optimal environment for enzymatic catalysis. Here, we describe ... 
nExcisive functors, canonical connections, and line bundles on the Ran space
(Springer International Publishing, 20210105)Abstract Let X be a smooth algebraic variety over k. We prove that any flat quasicoherent sheaf on $${\text {Ran}}(X)$$ ...

NFace GaN/AlGaN HEMTs Fabricated Through Layer Transfer Technology
(Institute of Electrical and Electronics Engineers, 200901)We present a new method to fabricate Nface GaN/AlGaN high electron mobility transistors (HEMTs). These devices are extremely promising for ultrahigh frequency applications where low contact resistances and excellent carrier ... 
Njettiness beam functions at N3LO
(Springer Berlin Heidelberg, 20200922)Abstract We present the first complete calculation for the quark and gluon Njettiness ( ...

Njettiness subtractions for gg → H at subleading power
(American Physical Society, 201801)Njettiness subtractions provide a general approach for performing fullydifferential nexttonexttoleading order (NNLO) calculations. Since they are based on the physical resolution variable Njettiness, T[subscript N], ... 
NLinked Glycans Are Assembled on Highly Reduced Dolichol Phosphate Carriers in the Hyperthermophilic Archaea Pyrococcus furiosus
(Public Library of Science, 201506)In all three domains of life, Nglycosylation begins with the assembly of glycans on phosphorylated polyisoprenoid carriers. Like eukaryotes, archaea also utilize phosphorylated dolichol for this role, yet whereas the ... 
Nmethyl dAspartate Channels Link Ammonia and Epithelial Cell Death Mechanisms in Helicobacter pylori Infection
(Elsevier BV, 201109)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 ... 
Npolar AlN buffer growth by MOVPE for transistor applications
(Japan Society of Applied Physics, 2018)We present the electrical characterization of Npolar AlN layers grown by metalorganic vapor phase epitaxy and the demonstration of Npolar AlNchannel metalsemiconductor fieldeffect transistors (MESFETs). A high ... 
nrelative categories: a model for the homotopy theory of nfold homotopy theories
(International Press of Boston, Inc., 201312)We introduce, for every integer n ≥ 1, the notion of an nrelative category and show that the category of the small nrelative categories is a model for the homotopy theory of nfold homotopy theories, i.e., homotopy ... 
An Nstage cascade of phosphorylation cycles as an insulation device for synthetic biological circuits
(Institute of Electrical and Electronics Engineers (IEEE), 201607)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 biology. ... 
NSubstituted 2Aminobiphenylpalladium Methanesulfonate Precatalysts and Their Use in C–C and C–N CrossCouplings
(201404)A series of phosphineligated palladium precatalysts based on Nmethyl and Nphenyl2aminobiphenyl have been developed. Substitution at the nitrogen center prevents the presence of traces of aminobiphenyls that contain ... 
N6methyladenosine RNA modification regulates embryonic neural stem cell selfrenewal through histone modifications
(Springer Science and Business Media LLC, 201801)Internal N 6methyladenosine (m6A) modification is widespread in messenger RNAs (mRNAs) and is catalyzed by heterodimers of methyltransferaselike protein 3 (Mettl3) and Mettl14. To understand the role of m6A in development, ...
