CXCR4-expressing Mist1+ progenitors in the gastric antrum contribute to gastric cancer development
(Impact Journals, LLC, 2017-11)
Mist1 was recently shown to identify a discrete population of stem cells within the isthmus of the oxyntic gland within the gastric corpus. Chief cells at the base of the gastric corpus also express Mist1. The relevance ...
Engineering the magnetic properties of hybrid organic-ferromagnetic interfaces by molecular chemical functionalization
(American Physical Society, 2011-11)
We have performed systematic first-principles calculations to tailor the magnetic properties at a hybrid organic-ferromagnetic interface by adsorbing organic molecules containing π(p[subscript z]) electrons onto a magnetic ...
Nanoantenna couplers for metal-insulator-metal waveguide interconnects
(SPIE--the International Society for Optical Engineering, 2010-08)
State-of-the-art copper interconnects suffer from increasing spatial power dissipation due to chip downscaling and RC delays reducing operation bandwidth. Wide bandwidth, minimized Ohmic loss, deep sub-wavelength confinement ...
Depth-resolved cathodoluminescence spectroscopy of silicon supersaturated with sulfur
(American Institute of Physics (AIP), 2013-01)
We investigate the luminescence of Si supersaturated with S (Si:S) using depth-resolved cathodoluminescence spectroscopy and secondary ion mass spectroscopy as the S concentration is varied over 2 orders of magnitude ...
The role of model dynamics in ensemble Kalman filter performance for chaotic systems
(Co-Action Publishing, 2011-10)
The ensemble Kalman filter (EnKF) is susceptible to losing track of observations, or ‘diverging’, when applied to large chaotic systems such as atmospheric and ocean models. Past studies have demonstrated the adverse impact ...
A Tutorial on Dual Decomposition and Lagrangian Relaxation for Inference in Natural Language Processing
(Association for the Advancement of Artificial Intelligence, 2012-10)
Dual decomposition, and more generally Lagrangian relaxation, is a classical method for combinatorial optimization; it has recently been applied to several inference problems in natural language processing (NLP). This ...
ON TWO FINITENESS CONDITIONS FOR HOPF ALGEBRAS WITH NONZERO INTEGRAL
(Scuola normale superiore di Pisa, 2015-06)
A Hopf algebra is co-Frobenius when it has a nonzero integral. It
is proved that the composition length of the indecomposable injective comodules over a co-Frobenius Hopf algebra is bounded. As a consequence, the coradical ...
Molecular dynamics computer simulation of scratch resistance testing of polymers: visualization
(Springer-Verlag, 2013-02)
Experimental scratch resistance testing provides two numbers: the penetration depth Rp and the healing depth Rh. In molecular dynamics computer simulations, we create a material consisting of N statistical chain segments ...
Genome-wide dissection of microRNA functions and cotargeting networks using gene-set signatures
(Elsevier, 2010-04)
MicroRNAs are emerging as important regulators of diverse biological processes and pathologies in animals and plants. Though hundreds of human microRNAs are known, only a few have known functions. Here, we predict human ...
Search for B→K[superscript (*)]νν̅ and invisible quarkonium decays
(American Physical Society, 2013-06)
We search for the flavor-changing neutral-current decays B→K[superscript (*)]νν̅ , and the invisible decays J/ψ→νν̅ and ψ(2S)→νν̅ via B→K[superscript (*)]J/ψ and B→K[superscript (*)]ψ(2S), respectively, using a data sample ...
