Ferroelectric Properties in Piezoelectric Semiconductor Zn<sub> 1-x</sub>M<sub>x</sub>O (M=Li, Mg) (1997)

Ferroelectric properties and the effect of Li + and Mg 2+ dopants in II–VI semiconductor ZnO were studied. The ferroelectric D – E loops were observed in Zn 1- x (Li 0.02 ·Mg x -0.02 )O, as well as in Zn 1- x Li x O. The transition temperature ( T c ) increases in proportion to the concentration of Mg 2+ ions, while it is almost constant (330 K) in Zn 1- x Li x O above x > 0.1. T c was 260 K for Zn 0.9 (Li 0.02 Mg 0.08 )O and 360 K for Zn 0.7 (Li 0.02 Mg 0.28 )O. An additional 20% of Mg increases T c by 100 K. The ferroelectric phase transition is strongly influenced by the introduction of small Li and Mg atoms instead of the host Zn atoms in wurtzite ZnO.
Energy Aware Computing through Probabilistic Switching: A Study of Limits (2005)

The main result in this paper establishes the energy savings derived by using probabilistic AND as well as NOT gates constructed from an idealized switch that produces a probabilistic bit (PBIT). A probabilistic switch produces the desired value as an output that is 0 or 1 with probability p, represented as a PBIT, and, hence, can produce the wrong output value with a probability of (1-p). In contrast with a probabilistic switch, a conventional deterministic switch produces a BIT whose value is always correct. Our switch-based gate constructions are a particular case of a systematic methodology developed for building energy-aware networks for computing, using PBITS. Interesting examples of such networks include AND, OR, and NOT gates (or, as functions, Boolean conjunction, disjunction, and negation, respectively). To quantify the energy savings, novel measures of "technology independent" energy complexity are also introduced - these measures parallel conventional machine-independent notions of computational complexity such as the algorithm's running time and space. Networks of switches can be related to Turing machines and to Boolean circuits, both of which are widely known and well-understood models of computation. Our gate and network constructions lend substance to the following thesis (established for the first time by K.V. Palem): the mathematical technique referred to as randomization yielding probabilistic algorithms results in energy savings through a physical interpretation based on statistical thermodynamics and, hence, can serve as a basis for energy-aware computing. While the estimates of the energy saved through PBIT-based probabilistic computing switches and networks developed rely on the constructs and thermodynamic models due to Boltzmann, Gibbs, and Planck, this work has also led to the innovation of probabilistic CMOS-based devices and computing frameworks. Thus, for completeness, the relationship between the physical models on which this work is based and the electrical domain of CMOS-based switching is discussed.
Concept drift learning with alternating learners (2017)

Data-driven predictive analytics are in use today across a number of industrial applications, but further integration is hindered by the requirement of similarity among model training and test data distributions. This paper addresses the need of learning from possibly nonstationary data streams, or under concept drift, a commonly seen phenomenon in practical applications. A simple dual-learner ensemble strategy, alternating learners framework, is proposed. A long-memory model learns stable concepts from a long relevant time window, while a short-memory model learns transient concepts from a small recent window. The difference in prediction performance of these two models is monitored and induces an alternating policy to select, update and reset the two models. The method features an online updating mechanism to maintain the ensemble accuracy, and a concept-dependent trigger to focus on relevant data. Through empirical studies the method demonstrates effective tracking and prediction when the steaming data carry abrupt and/or gradual changes.
Interactive Path Planning for Virtual Endoscopy (1999)

Virtual colonoscopy has been developed as a non-invasive computerized medical procedure for examining the entire colon to detect polyps. Our group has successfully implemented an interactive navigation using a physically-based camera control model and a hardware-assisted visibility algorithm. Unfortunately, the pre-processing (skeleton and potential field generations) consumes too much computing time to be acceptable in an interactive environment. In this work, we focus on skeleton simplification to eliminate excessive ramification. We perform the simplification before the skeleton generation. The idea is to utilize a hierarchical analysis of attractors to determine principal attractors. We also propose a dynamic target navigation for virtual endoscopy. We combine potentials derived from the distance between source and target positions and from the distance to the colon surface to guide path search processes. These potentials are essential to obtain priority in choosing the paths far away from colon wall and in the direction of target positions.

Streaming algorithms for k-core decomposition (2013)

A k -core of a graph is a maximal connected subgraph in which every vertex is connected to at least k vertices in the subgraph. k -core decomposition is often used in large-scale network analysis, such as community detection, protein function prediction, visualization, and solving NP-Hard problems on real networks efficiently, like maximal clique finding. In many real-world applications, networks change over time. As a result, it is essential to develop efficient incremental algorithms for streaming graph data. In this paper, we propose the first incremental k -core decomposition algorithms for streaming graph data. These algorithms locate a small subgraph that is guaranteed to contain the list of vertices whose maximum k -core values have to be updated, and efficiently process this subgraph to update the k -core decomposition. Our results show a significant reduction in run-time compared to non-incremental alternatives. We show the efficiency of our algorithms on different types of real and synthetic graphs, at different scales. For a graph of 16 million vertices, we observe speedups reaching a million times, relative to the non-incremental algorithms.
Robust observer based active damping control for LCL filtered grid connected converters using LMI criterion (2016)

The design of current controller of voltage source converter connected to the grid through an LCL filter becomes more and more challenging because of the LCL filter resonance behaviour and the uncertainty of the grid impedance value which may lead to instability problems. In this context, a robust active damping control for LCL filtered grid connected inverter under grid inductance variation is proposed in this paper. The two useful methodologies, Lyapunov stability theory and LMI approach, are adopted to design robust observer-based control for this class of uncertain systems. The simulations results are given to illustrate the effectiveness of this control. A comparison study of the results derived in this work with previous observer based active damping method shows the superiority of the proposed design strategy.

Blockade of mitochondrial calcium uniporter prevents cardiac mitochondrial dysfunction caused by iron overload (2013)

These findings strongly suggest that MCU could be the major route for iron uptake into cardiac mitochondria. The inhibition of MCU could be the novel pharmacological intervention for preventing iron-overload cardiomyopathy.
Influence of Tandem Inducers on the Performance of High Pressure Ratio Centrifugal Compressors (2015)

The uses of tandem inducers has been proposed in the past in an attempt to reduce the inducer shock losses and to improve the performance and operating range of centrifugal compressors. However throughout the literature the benefits/penalties of this type of compressor design are still unclear, with contradictory conclusions and very few studies attempting to understand the causes of the observed benefits/penalties. Additionally none of the cases reported for centrifugal compressors has looked into the impact of overlap between the inducer and the main blade. The current study looks into the different aspects of the design of centrifugal compressors with tandem inducers and their effect on the performance of a high flow coefficient, high pressure ratio centrifugal compressor. Aspects such as clocking, axial gap between the inducer and the compressor main blade, axial overlap, and the performance in combination with a vaned diffuser are discussed. Overall the results indicate that it is possible to design centrifugal compressors with tandem inducers that provide similar or even a slight performance benefit at design point, and that tandem inducers can provide significant performance benefits at off design conditions by improving the flow conditions along the main blade suction side, and by improving the inlet conditions to a vaned diffuser. The results also indicate that the impact of the axial gap between the inducer and the main blade has little impact on the compressor performance, that clocking will have a significant impact on the performance of the compressor and that the best performance will be obtained when the tandem inducer is almost aligned with the main blade of the compressor, since this avoids the blockage and losses incurred by other clocking arrangements.

The CBP co-activator stimulates E2F1/DP1 activity (1996)

The cell cycle-regulating transcription factors E2F1/DP1 activate genes whose products are required for S phase progression. During most of the G1 phase, E2F1/DP1 activity is repressed by the retinoblastoma gene product RB, which directly contacts the E2F1 activation domain and silences it. The E2F1 activation domain has sequence similarity to the N-terminal activation domain of E1A(12S), which contains binding sites for CBP as well as RB. Here, we present evidence that the CBP protein directly contacts E2F1/DP1 and stimulates its activation capacity. We show that CBP interacts with the activation domain of E2F1 both in vitro and in vivo. Deletion of four residues from the E2F1 activation domain reduces CBP binding as well as transcriptional activation, but still allows the binding of RB and MDM2. This deletion removes residues which are conserved in the N-terminal activation domain of E1A and which are required for the binding of CBP to E1A. When the E1A N-terminus is used as a competitor in squelshing experiments it abolishes CBP-induced activation of E2F1/DP1, whereas an E1A mutant lacking CBP binding ability fails to do so. These results indicate that CBP can act as a coactivator for E2F1 and suggest that CBP recognises a similar motif within the E1A and E2F1 activation domains. The convergence of the RB and CBP pathways on the regulation of E2F1 activity may explain the cooperativity displayed by these proteins in mediating the biological functions of E1A. We propose a model in which E1A activates E2F not only by removing the RB repression but also by providing the CBP co-activator.
The Danger Signal, Extracellular ATP, Is a Sensor for an Airborne Allergen and Triggers IL-33 Release and Innate Th2-Type Responses (2011)

The molecular mechanisms underlying the initiation of innate and adaptive proallergic Th2-type responses in the airways are not well understood. IL-33 is a new member of the IL-1 family of molecules that is implicated in Th2-type responses. Airway exposure of naive mice to a common environmental aeroallergen, the fungus Alternaria alternata, induces rapid release of IL-33 into the airway lumen, followed by innate Th2-type responses. Biologically active IL-33 is constitutively stored in the nuclei of human airway epithelial cells. Exposing these epithelial cells to A. alternata releases IL-33 extracellularly in vitro. Allergen exposure also induces acute extracellular accumulation of a danger signal, ATP; autocrine ATP sustains increases in intracellular Ca(2+) concentration and releases IL-33 through activation of P2 purinergic receptors. Pharmacological inhibitors of purinergic receptors or deficiency in the P2Y2 gene abrogate IL-33 release and Th2-type responses in the Alternaria-induced airway inflammation model in naive mice, emphasizing the essential roles for ATP and the P2Y(2) receptor. Thus, ATP and purinergic signaling in the respiratory epithelium are critical sensors for airway exposure to airborne allergens, and they may provide novel opportunities to dampen the hypersensitivity response in Th2-type airway diseases such as asthma.
Estimating subsurface parameter fields for seismic migration: Velocity model building (2014)

Abstract To produce a reliable image of the subsur-face, we must use a depth-migration scheme that requires a detailed model of the parameter fields for use by migration. Obtaining reliable values of all parameters for the full 3D volume to be imaged is perhaps impractical, so we make various simplifying assumptions. Even with such assumptions, inverting for a wide range of parameters given a limited and inconsistent data set is challenging. Ray-based tomography supplemented with waveform inversion can yield a suitable model. However, we often still need to fall back on various techniques that require manual intervention to incorporate detailed velocity anomalies into the migration model.
Planar Mesa Schottky Barrier Diode (1971)

Planar silicon technology has been used to fabricate mesa Schottky barrier diodes with high breakdown voltages. This method proves to be superior to alternate methods used to increase the breakdown voltage of Schottky diodes. The processing techniques and characteristics of mesa Schottky diodes are described in this paper.
Preparation of Diastereomerically Pure Dilignol Model Compounds (2011)

A gram-scale synthetic access to diastereomerically pure dilignol β-O-4 type model compounds, which represent valuable candidates for studies of lignin cleavage and valorization, is described. Following a straightforward procedure both diastereoisomers of 1,3-dilignols can be prepared. In the key-step, tert-butyl aryloxy esters are used as enolate precursors for additions on aldehydes. After separation, the resulting erythro and threo β-hydroxy esters are independently reduced to afford the target compounds in high yields.
Altered expression of wild-type p53 tumor suppressor gene during murine epithelial cell transformation. (1992)

An epidermal cell model in which initiated, benign tumor-producing and carcinoma stages were derived from a cloned parental cell strain was used to examine p53 expression during multistage epithelial carcinogenesis. Increased steady-state levels of p53 RNA were detected in squamous cell carcinomas compared to papilloma and normal epidermal cells. Nontumorigenic initiated cell precursors of the carcinomas exhibited normal p53 expression, localizing altered p53 regulation to the malignant conversion stage. Immunoprecipitation and Western immunoblot analyses demonstrated elevated levels of p53 protein in the moderately differentiated carcinoma compared to normal cells, and negligible levels of p53 in the poorly differentiated carcinoma cells. Sequence analysis of p53 complementary DNA from normal and carcinoma cells revealed no mutations in the coding or 5'- and 3'-untranslated regions, suggesting a novel mechanism of p53 inactivation.
FASCODE for the environment (FASE) (1995)

The Optical Physics Division of the Phillips Laboratory with support from the DoE Atmospheric Radiation Measurement (ARM) Program is developing a state-of-the-art line-by- line atmospheric radiative transfer model as the successor by FASCODE. The goal of this project is to create a computationally efficient model which contains the most up-to-date physics. The new model, known as FASCODE for the Environment, or `FASE', will combine the best features of FASCODE and LBLRTM, the DoE's standard radiative transfer model. FASE will also contain new features such as new cross-sections for heavy molecules, an improved solar irradiance model, and improvements to the Schumann-Runge bands and continuum. The code will be optimized for vectorized and/or parallel processing, put under configuration control for easy maintenance, and will be structured into separate modules for each function: atmospheric profiles, layer optical properties, radiative transfer, multiple- scattering, etc. This modular structure will allow for increased flexibility and easy customization of the code for specialized applications, such as a forward model for iterative inversion algorithms. Ease-of-use will be enhanced with improved input control structures and documentation to accommodate the needs of novice and advanced users. This paper addresses changes which have been made to FASCODE and LBLRTM to create FASE, and gives an overview of the modular structure and its capabilities.

Feline Leukemia-Virus Infection of Kittens: Mortality Associated With Atrophy of the Thymus and Lymphoid Depletion<xref ref-type="fn" rid="FN1">2</xref> (1971)

Cats infected neonatally with feline leukemia virus (FeLV) had a higher death rate than their littermate controls. Many showed retarded growth rate and died at 8–12 weeks of age. The major pathological finding was atrophy of the thymus and depletion of other lymphoid tissues; some cats had intercurrent infections. Catsdeveloping lymphoid malignancies as well as atrophy of the thymus died with either alimentary lymphosarcoma or lymphoblastic leukemia. Thesyndrome as found in 29 cats is described.
Specific and ubiquitous expression of different Zn finger protein genes in the mouse (1988)

Zinc finger proteins (Zfp) are members of a multigene family encoding Zn mediated nucleic acid binding proteins. They have been isolated from various organisms including yeast, Drosophila, Xenopus mouse and human. All Zfp share the 28-30 amino acid long finger repeats containing conserved residues at specific positions. Some of these proteins have been identified as transcriptional regulatory factors. In this paper, we describe the isolation, DNA sequence determination and the expression pattern in developing embryos and adult tissues of 3 new members of the mouse Zfp. All of them are expressed as multiple transcripts. Unaltered level of mkr5 expression could be detected in 10-15 day whole embryo RNAs but its level started to decrease from day 16. In the adult animal, predominant expression was detected only in the ovary. In contrast, mkr3 and 4 were expressed at a constant level in all embryos and tissues tested. These data suggest the presence of both tissue specific and ubiquitious Zfp in the mouse.
