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
(Institute of Electrical and Electronics Engineers (IEEE), 2016-07)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. ... -
N-Substituted 2-Aminobiphenylpalladium Methanesulfonate Precatalysts and Their Use in C–C and C–N Cross-Couplings
(2014-04)A series of phosphine-ligated palladium precatalysts based on N-methyl- and N-phenyl-2-aminobiphenyl have been developed. Substitution at the nitrogen center prevents the presence of traces of aminobiphenyls that contain ... -
N6-methyladenosine RNA modification regulates embryonic neural stem cell self-renewal through histone modifications
(Springer Science and Business Media LLC, 2018-01)Internal N 6-methyladenosine (m6A) modification is widespread in messenger RNAs (mRNAs) and is catalyzed by heterodimers of methyltransferase-like protein 3 (Mettl3) and Mettl14. To understand the role of m6A in development, ... -
N[superscript 6]-Formyllysine as a Biomarker of Formaldehyde Exposure: Formation and Loss of N[superscript 6]-Formyllysine in Nasal Epithelium in Long-Term, Low-Dose Inhalation Studies in Rats
(American Chemical Society (ACS), 2017-07)Exposure to both endogenous and exogenous formaldehyde has been established to be carcinogenic, likely by virtue of forming nucleic acid and proteins adducts such as N[superscript 6]-formyllysine. To better assess N[superscript ... -

NAD + supplementation rejuvenates aged gut adult stem cells
(Wiley, 2019-03)The tissue decline due to aging is associated with the deterioration of adult stem cell function. Here we show the number and proliferative activity of intestinal stem cells (ISCs) but not Paneth cells decline during aging, ... -
NAD+ and sirtuins in aging and disease
(Elsevier, 2014-08)Nicotinamide adenine dinucleotide (NAD[superscript +]) is a classical coenzyme mediating many redox reactions. NAD[superscript +] also plays an important role in the regulation of NAD[superscript +]-consuming enzymes, ... -
The [NAD[superscript +] over Sirtuin] Pathway Modulates Longevity through Activation of Mitochondrial UPR and FOXO Signaling
(Elsevier, 2013-07)NAD[superscript +] is an important cofactor regulating metabolic homeostasis and a rate-limiting substrate for sirtuin deacylases. We show that NAD[superscript +] levels are reduced in aged mice and Caenorhabditis elegans ... -
Nail: A Practical Tool for Parsing and Generating Data Formats
(Institute of Electrical and Electronics Engineers (IEEE), 2014-05)We present Nail, an interface generator that allows programmers to safely parse and generate protocols defined by a Parser-Expression based grammar. Nail uses a richer set of parser combinators that induce an internal ... -
NailO: Fingernails as an Input Surface
(Association for Computing Machinery (ACM), 2015-04)We present NailO, a nail-mounted gestural input surface. Using capacitive sensing on printed electrodes, the interface can distinguish on-nail finger swipe gestures with high accuracy (>92%). NailO works in real-time: we ... -
NAITRE study on the impact of conditional cash transfer on poor pregnancy outcomes in underprivileged women: protocol for a nationwide pragmatic cluster-randomised superiority clinical trial in France
(BMJ, 2017-09)Introduction: Prenatal care is recommended during pregnancy to improve neonatal and maternal outcomes. Women of lower socioeconomic status (SES) are less compliant to recommended prenatal care and suffer a higher risk of ... -
The Naïve Utility Calculus: Computational Principles Underlying Commonsense Psychology
(Elsevier, 2016-07)We propose that human social cognition is structured around a basic understanding of ourselves and others as intuitive utility maximizers: from a young age, humans implicitly assume that agents choose goals and actions to ... -
NAMPT Over-Expression Recapitulates the BRAF Inhibitor Resistant Phenotype Plasticity in Melanoma
(Multidisciplinary Digital Publishing Institute, 2020-12-20)Serine–threonine protein kinase B-RAF <b>(</b><i>BRAF)</i>-mutated metastatic melanoma (MM) is a highly aggressive type of skin cancer. Treatment of MM patients using BRAF/MEK inhibitors (BRAFi/MEKi) eventually leads ... -
Nano Day: Celebrating the Next Decade of Nanoscience and Nanotechnology
(American Chemical Society (ACS), 2016-10)Nanoscience and nanotechnology are poised to contribute to a wide range of fields, from health and medicine to electronics, energy, security, and more. These contributions come both directly in the form of new materials, ... -
