Electron-phonon coupling in a magic-angle twisted-bilayer graphene device (2021)

The importance of phonons in the strong correlation phenomena observed in twisted bilayer graphene (TBG) at the so-called magic-angle is under debate. Here we apply gate-dependent micro-Raman spectroscopy to monitor the G band linewidth in TBG devices of twist angles $θ=0^{\circ}$, $\sim 1.1^{\circ}$ (magic-angle) and $\sim 7^{\circ}$ (large angle). The results show a broad and p/n-asymmetric doping behavior at the magic-angle, in clear contrast to the behavior observed in twist angles above and below. Atomistic modeling reproduces the experimental observations, revealing how the unique electronic structure of magic-angle TBGs influences the electron-phonon coupling and, consequently, the G band linewidth. Our findings indicate a connection between electron-phonon coupling and experimental observations of strongly correlated phenomena in magic-angle TBG.

Scale-Up Synthesis of IID572: A New β-Lactamase Inhibitor (2020)

The new potentially best-in-class β-lactamase inhibitor IID572 was discovered by a late-stage functionalization approach. An alternative synthesis was developed to satisfy the short-term material need for toxicological studies in animals. The new synthetic strategy was built on two key features, an intramolecular azomethine ylide [3 + 2] cycloaddition that allowed the efficient formation of molecular complexity from readily available starting materials and an enzymatic resolution that resulted in high optical purity of a key intermediate.
H + CD4 Abstraction Reaction Dynamics:  Product Energy Partitioning (2005)

This paper presents experimental and theoretical studies of the product energy partitioning associated with the H + CD4 (nu = 0) --> HD + CD3 reaction for the collision energy range 0.5-3.0 eV. The theoretical results are based on quasiclassical trajectories from (1) first principles direct dynamics calculations (B3LYP/6-31G), (2) an empirical surface developed by Espinosa-García [J. Chem. Phys. 2002, 116, 10664] (EG), and (3) two semiempirical surfaces (MSINDO and reparametrized MSINDO). We find that most of the energy appears in product translation at energies just above the reactive threshold; however, HD vibration and rotation become quite important at energies above 1 eV, each accounting for over 20% of the available energy above 1.5 eV, according to the B3LYP calculations. The barrier on the B3LYP surface, though being later than that on EG, predicts significantly higher HD vibrational excitation than EG. This deviation is contradictory to what would be expected on the basis of the Polanyi rules and derives from modest differences in the potential energy surfaces. The CD3 internal energy is generally quite low, and we present detailed rotational state distributions which show that the CD3 rotational distribution is largely independent of collision energy in the 0.75-1.95 eV range. The most populated rotational levels are N = 5 and 6 on B3LYP, with most of that excitation being associated with motion about the C2 axes, rather than C3 axis, of the CD3 product, in good agreement with the experimental results. Through our extensive studies in this and previous work concerning the scattering dynamics, we conclude that B3LYP/6-31G provides the best available description of the overall dynamics for the title reaction at relatively high collision energies.

Very high quality thin gate oxide formation technology (1995)

A new approach to gate oxidation processes, where oxide growth is completely controlled by ultraclean technology, is presented. This approach with chemical preoxide growth in ozonized ultrapure water as a passivation layer, ramp-up in an Ar ambient with a negligible amount of residual water, and formation of high quality oxide in a reductive ambient with H radicals can completely eliminate uncontrolled oxide growth and provide very high quality thin gate oxide. The impact of organic contamination on the gate integrity is also discussed. A newly developed Fourier transform infrared technique is used for the evaluation of organic contamination on the wafer surface.

Flexibility, manageability, and performance in a Grid storage appliance (2003)

We present NeST a flexible software-only storage appliance designed to meet the storage needs of the Grid. NeST has three key features that make it well-suited for deployment in a Grid environment. First, NeST provides a generic data transfer architecture that supports multiple data transfer protocols (including GridFTP and NFS), and allows for the easy addition of new protocols. Second, NeST is dynamic, adapting itself on-the-fly so that it runs effectively on a wide range of hardware and software platforms. Third, NeST is Grid-aware, implying that features that are necessary for integration into the Grid, such as storage space guarantees, mechanisms for resource and data discovery, user authentication, and quality of service, are a part of the NeST infrastructure.

Abstract 200: Novel Interaction of Spinophilin with Alpha1a-Adrenergic Receptor and its Genetic Variant in Cardiovascular Cells (2014)

Activation of α 1 -Adrenergic Receptors (α 1 ARs), members of the G protein-coupled receptor (GPCR) superfamily, in response to stimulation of the sympathetic nervous system by catecholamines plays a major role in regulating cardiovascular (CV) function. Among three α 1 AR subtypes (α 1a ,α 1b ,α 1d ), α 1a ARs predominate in human resistant vessels and in heart. Recently, we discovered that naturally occurring human α 1a AR-G247R (247R) genetic variant, identified in the 3 rd intracellular loop (3iL) of the receptor in highly hypertensive patient, triggers constitutive hyperproliferation in CV cells (cardiomyoblasts, smooth muscle cells (SMC) and fibroblasts), which may lead to myocardial fibrosis and remodeling. In fibroblasts and cardiomyoblasts 247R triggered hyperproliferation is due to constitutive active coupling to Gq-independent βarrestin1/MMP/EGFR/ERK dependent pathway, while in SMC it is Gq- and MMP/EGFR/ERK-dependent. Here we report that α 1a AR-WT (WT) and 247R differentially interact with ubiquitous multi-domain scaffold protein spinophilin (SPL) that binds to 3iL of several GPCRs competing with arrestin thereby prolonging their signaling. The role of SPL in CV regulation is poorly studied. We hypothesized that SPL mediates constitutive signaling of 247R and examined whether SPL directly interacts with α 1a AR-WT or 247R. Our preliminary results reveal a direct interaction of SPL with WT and 247R: the SPL-WT interaction appears to be stronger as determined by co-immunoprecipitation. Different domains of SPL differentially interact with WT or 247R. SPL 1-480aa fragment interacts stronger with WT indicating interaction with 3iL, while SPL 480-817 fragment interacts stronger with 247R. Our preliminary results also demonstrate that 247R expression in all three cell types elevates endogenous SPL protein levels. Importantly, inhibition of SPL expression with specific siRNA reduces 247R-triggered hyperproliferation in SMC and cardiomyoblasts to near normal levels, while SPL knockdown has no effect in WT cells. Thus, we identified SPL as a novel protein involved in interacting and signaling of α 1a AR and its genetic variant in CV cells and that SPL could be considered as a potentially novel target in α 1a AR-mediated cardiovascular disorders.

Hybrid Force/Velocity Control “With Compliance Estimation via Strain Elastography for Robot Assisted Ultrasound Screening (2018)

Ultrasound scanning provides a noninvasive solution for additional screening in breast cancer detection and could potentially be improved by utilizing a human-robot collaborative system. Alternative ultrasound modalities, such as elastography, offer promising improvements over current sonography cancer detection rates but require stability and knowledge of applied force. A human-robot scanning system could leverage the sonographer's capabilities to select transducer placement while the robot maintains stability during scanning. This paper presents a novel hybrid force velocity controller for ultrasound scanning which utilizes elastography to provide compliance feedback and improve controller performance. We explore the sensitivity of the elastography algorithm to initial elasticity assumptions and analyze the performance gains of compliance feedback. The results of our study show that our proposed controller provides a performance improvement when poor initial tissue compliance estimates are used.
Generalized Sampling on Graphs With Subspace and Smoothness Priors (2020)

We propose a framework for generalized sampling of graph signals that parallels sampling in shift invariant (SI) subspaces. This framework allows for arbitrary input signals which are not constrained to be bandlimited. Furthermore, the sampling and reconstruction filters may be different. We present design methods of the correction filter that compensate for these differences and lead to closed form expressions in the graph frequency domain. In this study, we consider two priors on graph signals: The first is a subspace prior, where the signal is assumed to lie in a periodic graph spectrum (PGS) subspace. The PGS subspace is proposed as a counterpart of the SI subspace used in standard sampling theory. The second is a smoothness prior that imposes a smoothness requirement on the graph signal. We suggest the use of recovery techniques when the recovery filter can be optimized and under a setting in which a predefined filter must be used. Sampling is performed in the graph frequency domain, which is a counterpart of “sampling by modulation” used in SI subspaces. We compare our approach with existing sampling techniques on graph signal processing. The effectiveness of the proposed generalized sampling approach is validated numerically through several experiments.
Improving Glycopeptide Synthesis:  A Convenient Protocol for the Preparation of β-Glycosylamines and the Synthesis of Glycopeptides (2005)

[reaction: see text] Herein we apply a recently introduced protocol using ammonium carbamate in methanol to the amination of crude chitobiose leading to 1,beta-aminochitobiose. This simple, one-step procedure allows a facile preparation of unstable glycosylamines in contrast to the commonly implemented ammonium bicarbonate based amination of water-soluble carbohydrates. The new amination protocol leads to an improved synthesis of the key chitobiosyl-asparagine building block for the SPPS of glycopeptides. The utility of the method is demonstrated with the synthesis of a 39-amino acid glycoprotein.
IκB Kinase ε Phosphorylates TRAF2 To Promote Mammary Epithelial Cell Transformation (2012)

NF-κB transcription factors are central regulators of inflammation and when dysregulated contribute to malignant transformation. IκB kinase ε (IKKε; IKKi, encoded by IKBKE) is a breast oncogene that is amplified in 30% of breast cancers and drives transformation in an NF-κB-dependent manner. Here we demonstrate that IKKε interacts with and phosphorylates tumor necrosis factor receptor-associated factor 2 (TRAF2) at Ser11 in vitro and in vivo. This activity promotes Lys63-linked TRAF2 ubiquitination and NF-κB activation and is essential for IKKε transformation. Breast cancer cells that depend on IKKε expression for survival are also dependent on TRAF2. This work defines TRAF2 phosphorylation to be one key effector of IKKε-induced mammary epithelial cell transformation.
Family‐based association study of schizophrenia with 444 markers and analysis of a new susceptibility locus mapped to 11q13.3 (2004)

Family-based linkage disequilibrium (LD) mapping has been suggested as a powerful and practical alternative to linkage analysis. We have performed a genome-wide LD survey of susceptibility loci for schizophrenia in a Japanese population. We first typed 119 schizophrenic pedigrees (357 individuals) using 444 microsatellite markers, and analyzed the data using the pedigree disequilibrium test. This analysis revealed 14 markers demonstrating significant transmission distortion. To corroborate these findings, the statistical methods were changed to the extended transmission disequilibrium test (ETDT), using 80 independent complete trios (schizophrenic proband and both parents), with 68 derived from initial pedigrees and 12 newly recruited trios. ETDT supported two markers for continued association, D11S987 on 11q13.3 (P = 0.00009) and D16S423 on 16p13.3 (P = 0.002). We scrutinized the most significant genomic locus on 11q11-13 by adding 26 new markers for analysis. Results of three-marker haplotype analysis in the region showed evidence of association with schizophrenia (most significant haplotype P = 0.0005, global P = 0.022). Although the present study may have missed other potential genomic intervals because of the sparse mapping density, we hope that it has identified promising anchor points for further studies to identify risk-conferring genes for schizophrenia in the Japanese population. In addition, we provide useful information on genomic LD structures in Japanese populations, which can be used for LD mapping of complex diseases.

Least-Squares Directional Intra Prediction in H.264/AVC (2010)

A new intra-prediction mode for the H.264/AVC standard is proposed. Each pixel within a block is predicted by a weighted sum of its neighbours, according to an <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">N</i> th order Markov linear model. The weights are obtained through a least-squares estimate from reconstructed data in the neighbouring blocks, so that no overhead is necessary to convey the weights to the decoder. Results show significant improvements in H.264/AVC compression for images that are rich in directional structures, and moderate improvements for the other images and sequences tested.
Inter‐harmonics monitoring method based on PMUs (2017)

More and more inter‐harmonics are brought to the power grid due to the integration of renewables and the wide‐area deployments of the electronic devices. This may lead to the exacerbation power system stability problems such as the subsynchronous oscillation in western China. The synchronisation and high‐reporting rates of phasor measurement units (PMUs) make them an effective tool to monitor the appearance, propagation and distribution of inter‐harmonics for protection and control strategies. In this study, the instantaneous powers of the single phase and the three phase that contain inter‐harmonics are analysed. The phasor value of the signal containing the inter‐harmonics is computed. It is found that the analysis based on the instantaneous power, phasor magnitude or phasor angle cannot distinguish whether the harmonic is subsynchronous or supersynchronous. Then, an inter‐harmonics monitoring method that is based on complex numbers of phasor measured by PMUs is proposed in this study. This proposed method has been implemented in the main station of the wide‐area measurement system in western China. A number of field data events are used to verify the correctness of the theoretical derivations.
