A Low-Cost, Tiled Embedded Smart Camera System for Computer Vision Applications (2007)

In this demonstration, we present a low-resolution smart camera node with a custom-designed image sensor chip and peer-to-peer networking capabilities. Each camera can perform focal plane processing, and also has the computational power of the embedded controllers. Cameras can send data, such as results of image processing and feature extraction, over a peer-to-peer network. The distributed nature of such a system allows for increased scalability and robustness, and decreased bandwidth requirement over conventional server based systems. In our ongoing work, these lower-cost embedded smart cameras are being tiled instead of fabricating a higher-resolution sensor as a single chip. In our paper, we provide a detailed comparison of fabricating a higher-resolution sensor as a single chip and tiling lower-resolution embedded smart cameras in order to give motivation, and demonstrate the advantages. The comparison is made in terms of bandwidth, clock frequency, area, power, cost and global computations.
Complex genomic rearrangement in CCS‐LacZ transgenic mice (2007)

The cardiac conduction system (CCS)-lacZ insertional mouse mutant strain genetically labels the developing and mature CCS. This pattern of expression is presumed to reflect the site of transgene integration rather than regulatory elements within the transgene proper. We sought to characterize the genomic structure of the integration locus and identify nearby gene(s) that might potentially confer the observed CCS-specific transcription. We found rearrangement of chromosome 7 between regions D1 and E1 with altered transcription of multiple genes in the D1 region. Several lines of evidence suggested that regulatory elements from at least one gene, Slco3A1, influenced CCS-restricted reporter gene expression. In embryonic hearts, Slco3A1 was expressed in a spatial pattern similar to the CCS-lacZ transgene and was similarly neuregulin-responsive. At later stages, however, expression patterns of the transgene and Slco3A1 diverged, suggesting that the Slco3A1 locus may be necessary, but not sufficient to confer CCS-specific transgene expression in the CCS-lacZ line.
IONIC CONDUCTIVITY AND ELECTRICAL PROPERTIES OF CARBOXYMETHYL CELLULOSE - NH4Cl SOLID POLYMER ELECTROLYTES (2016)

In this present work, carboxymethyl cellulose (CMC) – ammonium chloride (NH4Cl) solid polymer electrolyte (SPE) films were prepared by solution casting method. The ionic conductivity and electrical properties of SPE films were investigated using Electrical Impedance Spectroscopy. SPE film containing 16 wt. % NH4Cl exhibited the highest ionic conductivity of 1.43 x 10-3 S/cm at ambient temperature, 303K. The temperature dependence SPE films showed an Arrhenius-type relation where the regression values obtained from the log conductivity versus reciprocal temperature is close to unity (R2≈1). The electrical properties have been measured as a function of frequency of Ԑr,Ԑi, Mr, Mi shown a non-Debye type behavior
[Paper] A Low Noise and High Sensitivity Image Sensor with Imaging and Phase-Difference Detection AF in All Pixels (2016)

In this paper, we describe a device structure and optical design for a CMOS image sensor with phase-difference detection photodiodes (PD) for autofocus (AF) function. The individual pixel of this image sensor is composed of two horizontally displaced PDs separated by a PN junction. All the effective pixels function as both the imaging and the phase-difference detection AF (PDAF). We have realized a low dark random noise (1.8e- at 1PD, 2.5e- at 1pixel) and high sensitivity (78Ke-/lx.sec at 1green pixel) image sensor with the imaging and the PDAF functions in all the effective pixels.
Three component coupling reactions of N-acetyl-2-azetine- rapid stereoselective entry to 2,3,4-trisubstituted tetrahydroquinolines (2002)

N-Acetyl-2-azetine undergoes Lewis acid catalysed [4 + 2]-cycloaddition with imines derived from aromatic amines and gave a 1:1 mixture of exo-endo diastereoisomeric azetidine cycloadducts which reacted further with aromatic amine, to give 2,3,4-trisubsitituted tetrahydroquinolines in good to excellent yield, predominantly as one diastereoisomer.
B1-Type Cyclin-Dependent Kinases Are Essential for the Formation of Stomatal Complexes in Arabidopsis thaliana (2004)

Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In yeasts, only one CDK is sufficient to drive cells through the cell cycle, whereas higher eukaryotes developed a family of related CDKs. Curiously, plants contain a unique class of CDKs (B-type CDKs), whose function is still unclear. We show that the CDKB1;1 gene of Arabidopsis (Arabidopsis thaliana) is highly expressed in guard cells and stomatal precursor cells of cotyledons, suggesting a prominent role for B-type CDKs in stomatal development. In accordance, transgenic Arabidopsis plants with reduced B-type CDK activity had a decreased stomatal index because of an early block of meristemoid division and inhibition of satellite meristemoid formation. Many aberrant stomatal cells were observed, all of them blocked in the G2 phase of the cell cycle. Although division of stomatal precursors was inhibited, cells still acquired stomatal identity, illustrating that stomatal cell differentiation is independent of cellular and nuclear division.
Data from Combined Inhibition of G9a and EZH2 Suppresses Tumor Growth via Synergistic Induction of IL24-Mediated Apoptosis (2023)

&lt;div&gt;Abstract&lt;p&gt;G9a and EZH2 are two histone methyltransferases commonly upregulated in several cancer types, yet the precise roles that these enzymes play cooperatively in cancer is unclear. We demonstrate here that frequent concurrent upregulation of both G9a and EZH2 occurs in several human tumors. These methyltransferases cooperatively repressed molecular pathways responsible for tumor cell death. In genetically distinct tumor subtypes, concomitant inhibition of G9a and EZH2 potently induced tumor cell death, highlighting the existence of tumor cell survival dependency at the epigenetic level. G9a and EZH2 synergistically repressed expression of genes involved in the induction of endoplasmic reticulum (ER) stress and the production of reactive oxygen species. IL24 was essential for the induction of tumor cell death and was identified as a common target of G9a and EZH2. Loss of function of G9a and EZH2 activated the IL24-ER stress axis and increased apoptosis in cancer cells while not affecting normal cells. These results indicate that G9a and EZH2 promotes the evasion of ER stress–mediated apoptosis by repressing &lt;i&gt;IL24&lt;/i&gt; transcription, therefore suggesting that their inhibition may represent a potential therapeutic strategy for solid cancers.&lt;/p&gt;Significance:&lt;p&gt;These findings demonstrate a novel role for G9a and EZH2 histone methyltransferases in suppressing apoptosis, which can be targeted with small molecule inhibitors as a potential approach to improve solid cancer treatment.&lt;/p&gt;&lt;/div&gt;
Analysis of Structural Variability with Computer Algebra (1988)

Computer algebra provides an environment of conceptual algorithmic development since the relation between the responses and inputs are maintained all along. The closed‐form algebraic formulation removes not only much tedium in lengthy derivations but also virtually all inadvertent mistakes. Furthermore, the accompanying numerical capability with indefinite precision yields consistent numerical results especially in differentiations unless sophisticated adaptive finite difference schemes are sought. In this paper a two‐bar truss with imprecise nodal position sufficiently captured the essential difficulties in numerical computations for general finite elements with stochastic system parameters. Substitutions based on algebraic pattern recognition enormously simplified the expressions for higher order derivatives of the element stiffness matrix. Thus precise numerical results of probability integrals demanded in complicated problems of system reliability analysis could be furnished without incurring intermediate round‐off errors as prevalent in conventional (FORTRAN‐type) programs.
How surface-enhanced chemiluminescence depends on the distance from a corrugated metal film (2006)

Peroxidase labeled streptavidin was immobilized onto the surface of bulk and clusterlike metal films at a distance controlled by a peptide chain with a length between 1.3 and 7.8nm. Luminol chemiluminescence which occurred at peroxidase vicinity depends on the metal nanostructure. When peroxidase is attached on a bulklike film, chemiluminescence increases monotonously with the distance because of a decrease of the light emission quenching by metal. When peroxidase is attached on a clusterlike film, chemiluminescence undergoes a complex variation with the metal/catalyst distance evidencing a competition between the already mentioned quenching process and a nanostructure-induced catalysis enhancement.
An eigenvector approach for inverse synthetic aperture radar (ISAR) motion compensation and imaging (2002)

Inverse synthetic aperture radar (ISAR) is a high resolution imaging radar. The image reconstruction of ISAR involves two steps; motion compensation and image formation. In this paper, an eigenvector approach is proposed to carry out ISAR motion compensation. The eigenvector approach is identified as the maximal likelihood (ML) phase estimation of translational motion. The relationship of the eigenvector approach to other methods is also investigated. The results of processing simulated data and real data demonstrate that the eigenvector approach is correct and effective.
Increasing the number of strides for conflict-free vector access (1992)

Address transformation schemes, such as skewing and linear transformations, have been proposed to achieve conflict-free vector access for some strides in vector processors with multi-module memories. In this paper, we extend these schemes to achieve this conflict-free access for a larger number of strides. The basic idea is to perform an out-of-order access to vectors of fixed length, equal to that of the vector registers of the processor. Both matched and unmatched memories are considered: we show that the number of strides is even larger for the latter case. The hardware for address calculations and access control is described and shown to be of similar complexity as that required for access in order.
Effective Magnetic Monopoles and Universal Conductance Fluctuations (2010)

The observation of isolated positive and negative charges, but not isolated magnetic north and south poles, is an old puzzle. Instead, evidence of effective magnetic monopoles has been found in the abstract momentum space. Apart from Hall-related effects, few observable consequences of these abstract monopoles are known. Here, we show that it is possible to manipulate the monopoles by external magnetic fields and probe them by universal conductance fluctuation measurements in ferromagnets with strong spin-orbit coupling. The observed fluctuations are not noise, but reproducible quasiperiodic oscillations as a function of magnetization direction, a novel Berry phase fingerprint of the magnetic monopoles.
Global Instability in Fully Nonlinear Systems (1996)

Existence of a saturated steady solution of a nonlinear evolution equation subject to a boundary condition at $x\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$, called a nonlinear global mode, is illustrated on the real subcritical Ginzburg-Landau model. Such a nonlinear global mode is shown to exist whereas the flow is linearly stable, convectively unstable, or absolutely unstable. If the linearized evolution operator is absolutely unstable, then a global mode exists but the converse is false. This result relies only on the existence of a structurally unstable heteroclinic orbit in the phase space and is likely to be generic as demonstrated by the supercritical Ginzburg-Landau and the van der Pol-Duffing equations.
Terrae incognitae: o lugar da imaginação na geografia (2014)

Quais sao as terras incognitas ainda existentes? Em um primeiro vislumbre, pode parecer que sao poucas, se considerarmos incognitas apenas aquelas nunca tocadas pelo homem. Mas John Wright nos incita a pensarmos que a pouca extensao e profundidade do nosso conhecimento, alem dos limites daquilo que pode ser conhecido por um individuo, transforma todo o planeta em um conjunto de pequenas terras incognitas. E na permanente busca por tornar estas terras “cognitas” que devemos valorizar a imaginacao e a subjetividade como qualidades fundamentais para um bom geografo, e para uma ciencia mais clara, viva, condizente com a realidade da vida. Wrigth nos propoe, finalmente, o constante estudo do conhecimento geografico – a geosofia – que lida com a natureza e expressao da geografia em sentido amplo, ou seja, a geografia praticada por todos nos.
Polygenic risk scoring in the human embryo: reproductive genetics, final frontier? (2020)

The use of DNA to predict disease and discern risks in advance could lead to substantial improvements in the quality, length, and productivity of human life. We are now on the horizon of applying machine-learning analysis of information from population-wide medical records and genome-wide DNA repositories to reduce the burden of disease in humans. Thousands of publications derived from new resources, such as the Million Veteran Program ( 1 Gaziano J.M. Concato J. Brophy M. Fiore L. Pyarajan S. Breeling J. et al.

PLoS Med. 2015; 12e1001779 Crossref PubMed Scopus (2349) Google Scholar ), have led to the development of accurate DNA-based prediction of risk for many human diseases, a concept previously postulated by pioneers in reproductive medicine ( 3 Schulman J.D.

High speed 3-D registration using GPU (2008)

This paper describes high speed 3D object recognition based on DAI (depth aspect image) matching and M-ICP (modified iterative closest point). We regards GPU(graphic processing units) as coprocessor which are capable of computation for general purpose. We proposed 3D object recognition method which consists of two step pose estimation and positioning, i.e. the DAI matching for coarse step and HM-ICP (hierarchical M-ICP) for fine one Our method on GPU which has remarkable performance for parallel computation. The experimental results show the effectiveness of our method. This method can process 2 or 3 times faster than the original one, although the calculation amount of this method is at least 20 times bigger than the original one. Additionally, its processing time is more stabler than original method.
On-chip hotplate for temperature control of CMOS SAW resonators (2008)

Due to the sensitivity of the piezoelectric layer in surface acoustic wave (SAW) resonators to temperature, a method of achieving device stability as a function of temperature is required. This work presents the design, modeling and characterization of integrated dual-serpentine polysilicon resistors as a method of temperature control for CMOS SAW resonators. The design employs the oven control temperature stabilization scheme where the devicepsilas temperature is elevated to higher than T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">max</sub> to maintain constant device temperature. The efficiency of the polysilicon resistor as a heating element was verified through a 1-D partial differential equation model, 3-D CoventorWarereg finite element simulations and measurements using Compixreg thermal camera. To verify that the on-chip hotplate is effective as a temperature control method, both DC and RF measurements of the heater together with the resonator were conducted. Experimental results have indicated that the TCF of the CMOS SAW resonator of -97.2 ppm/degC has been reduced to -23.19 ppm/degC when heated to 56degC.

Effects of Incremental Levels of 慣-Tocopherol Acetate on Performance, Nutrient Digestibility and Meat Quality of Commercial Broilers (2005)

This experiment was conducted to explore the efficacy of -tocopherol acetate (AT), a commercial supplement containing tocopherols, in commercial broilers. Three hundred and thirty Ross broiler chicks (4-d old) were randomly distributed and allotted to five dietary treatments for six weeks. Each treatment comprised 3 pens as replicates containing 22 chicks per pen. The five dietary treatments were: 0 mg/kg AT (negative control); 10 mg/kg AT; 50 mg/kg AT; 100 mg/kg AT; and 200 mg/kg AT; respectively, supplied totally by the supplement under study. Supplementation of AT improved weight gain significantly (p<0.05), with higher values in the 100 and 200 mg/kg AT fed group than the control during all phases of study, but feed intake remained unaffected. The nutrient digestibility studies conducted after 15 and 35 days of experimental feeding showed significantly higher digestibility of CP, ether extract and gross energy, in these two groups over the control diet. Carcass traits like dressing percentage and the color of the breast meat did not differ significantly due to treatments, but significantly (p = 0.0152) lower abdominal fat percent was noted in the 200 mg/kg fed group. Higher (p = 0.0003) tibia bone strength was noticed in groups fed diets above 50 mg/kg AT because of higher bone mineral content. The serum levels of tocopherols were not influenced but the muscle tocopherols content showed a positive linear trend with the dietary levels supplemented. The thio-barbituric acid reactive substances (TBARS) level in meat also suggested that supplemental AT has a protective role in rancidity. Overall, it could be concluded that AT supplementation at higher levels was found beneficial for growth and increased chicken meat quality. (

Strained Silicon–Germanium-On-Insulator n-MOSFET With Embedded Silicon Source-and-Drain Stressors (2008)

In this letter, a strained silicon-germanium (SiGe) n-channel field-effect transistor (n-FET) featuring embedded silicon (Si) source-and-drain (S/D) stressors is demonstrated. A novel Ge-condensation technique was employed to form Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.75</sub> Ge <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.25</sub> -on-insulator (SGOI) substrates with excellent surface quality.

This leads to a 36% rise in linear drain-current and a 21% rise in saturation drive current over control SiGe channel devices at a fixed off-state current. Increasing the recess depth in S/D regions prior to the selective epitaxial growth of Si increases the channel stress, thus, a higher saturation drive-current enhancement can be achieved.
