Developmental Roles of FUSE Binding Protein 1 (Fubp1) in Tooth Morphogenesis (2020)

FUSE binding protein 1 (<i>Fubp1</i>), a regulator of the c-Myc transcription factor and a DNA/RNA-binding protein, plays important roles in the regulation of gene transcription and cellular physiology. In this study, to reveal the precise developmental function of <i>Fubp1</i>, we examined the detailed expression pattern and developmental function of <i>Fubp1</i> during tooth morphogenesis by RT-qPCR, in situ hybridization, and knock-down study using in vitro organ cultivation methods. In embryogenesis, <i>Fubp1</i> is obviously expressed in the enamel organ and condensed mesenchyme, known to be important for proper tooth formation. Knocking down <i>Fubp1</i> at E14 for two days, showed the altered expression patterns of tooth development related signalling molecules, including <i>Bmps</i> and <i>Fgf4</i>. In addition, transient knock-down of <i>Fubp1</i> at E14 revealed changes in the localization patterns of c-Myc and cell proliferation in epithelium and mesenchyme, related with altered tooth morphogenesis. These results also showed the decreased amelogenin and dentin sialophosphoprotein expressions and disrupted enamel rod and interrod formation in one- and three-week renal transplanted teeth respectively. Thus, our results suggested that <i>Fubp1</i> plays a modulating role during dentinogenesis and amelogenesis by regulating the expression pattern of signalling molecules to achieve the proper structural formation of hard tissue matrices and crown morphogenesis in mice molar development.
Magneto-acoustic oscillator (2017)

We demonstrate a hybrid oscillator system that combines the tunability of spin torque oscillators (STOs) with the exceptional quality factor (Q) of a high-overtone bulk acoustic resonator (HBAR) in a 2-chip system. The demonstrated magneto-acoustic oscillator (MAO) has a tuning range of 5% at 4 GHz with 175 kHz 3 dB linewidth. When compared to STOs we achieve a 200× reduction in linewidth, while retaining the original tuning range.
Jammed lattice sphere packings (2013)

We generate and study an ensemble of isostatic jammed hard-sphere lattices. These lattices are obtained by compression of a periodic system with an adaptive unit cell containing a single sphere until the point of mechanical stability. We present detailed numerical data about the densities, pair correlations, force distributions, and structure factors of such lattices. We show that this model retains many of the crucial structural features of the classical hard-sphere model and propose it as a model for the jamming and glass transitions that enables exploration of much higher dimensions than are usually accessible.

A cobalt complex with a bioinspired molybdopterin-like ligand: a catalyst for hydrogen evolution (2016)

Cobalt dithiolene complexes are a new class of H2-evolving catalysts. Here we describe the preparation, the structure and the catalytic activity of an original cobalt complex using a bioinspired ligand, a quinoxaline-pyran-fused dithiolene derivative (qpdt(2-)) that mimics the molybdopterin cofactor present in the active sites of formate dehydrogenases. This complex displays very good activity for electrochemical proton reduction under weak acid conditions in terms of turnover frequency, faradic yields and stability. Density functional theory calculations show that protonation of a nitrogen atom of the ligand decreases overpotentials by 520 mV and H2 formation proceeds via protonation of an intermediate Co-H hydride, with an adjacent S atom of the dithiolene ligand serving as a proton relay.
Elimination of vector changes due to sector changes with DTC (2015)

In this paper it has been investigated if there is a possibility to reduce the switching frequency for a two-level inverter by improving the direct torque control (DTC) algorithm by adding a non-switching condition when a new sector is entered. It is believed that the DTC switching table can be improved by adding a non-switching condition when sector change occurs. This will reduce the number of switching actions by up to 12 per electrical rotation without interfering with the electrical machine performance.
Effector Biology of Plant-Associated Organisms: Concepts and Perspectives (2012)

Every plant is closely associated with a variety of living organisms. Therefore, deciphering how plants interact with mutualistic and parasitic organisms is essential for a comprehensive understanding of the biology of plants. The field of plant-biotic interactions has recently coalesced around an integrated model. Major classes of molecular players both from plants and their associated organisms have been revealed. These include cell surface and intracellular immune receptors of plants as well as apoplastic and host-cell-translocated (cytoplasmic) effectors of the invading organism. This article focuses on effectors, molecules secreted by plant-associated organisms that alter plant processes. Effectors have emerged as a central class of molecules in our integrated view of plant-microbe interactions. Their study has significantly contributed to advancing our knowledge of plant hormones, plant development, plant receptors, and epigenetics. Many pathogen effectors are extraordinary examples of biological innovation; they include some of the most remarkable proteins known to function inside plant cells. Here, we review some of the key concepts that have emerged from the study of the effectors of plant-associated organisms. In particular, we focus on how effectors function in plant tissues and discuss future perspectives in the field of effector biology.
Myocardial temperature distribution under cw Nd:YAG laser irradiation in in vitro and in vivo situations: theory and experiment (1995)

Tissue samples ranging from 2 to 16 mm in thickness were irradiated at 1064 nm with energies ranging from 40 to 2400 J. Coagulation lesions of in vitro and in vivo experiments were subjected to temperature profiling and submitted for histology. Irreversible damage was calculated with the damage integral formalism, following the bioheat equation solved with Monte Carlo computer light-distribution simulations. Numerical temperature rise and coagulation depth compared well with the in vitro results. The in vivo data required a change in the optical properties based on integrating sphere measurements for high irradiance to make the experimental and numerical data converge. The computer model has successfully solved several light-tissue interaction situations in which scattering dominates over absorption.
Blood pressure is associated with retinal vessel signs in preadolescent children (2010)

Elevated BP is associated with narrower retinal arterioles in preadolescent boys and girls, and also with wider retinal venules in boys. These data provide further evidence of early microvascular changes associated with high BP in older children.
The role of interlayer grafting on the mechanical properties of magadiite/styrene‐butadiene rubber composites (2017)

ABSTRACT This work examines the mechanisms by which magadiite (MGD), a synthetic layered silicate, acts as an active filler to provide high levels of mechanical reinforcement in styrene‐butadiene rubber (SBR) composites. Cetyltrimethylammonium (CTA + ) expands the MGD layer spacing and promotes intercalation of SBR and silane coupling agent (Si69); the resulting CMGD/SBR composites have greater tensile moduli than comparable silica/SBR composites. CMGD was reacted in solution with Si69 (or MPTES) to prepare “pre‐grafted” MGD with varying levels of interlayer silane functionalization (SMGD). If the silane graft density is relatively low, the resulting SMGD/SBR composite has mechanical properties comparable to CMGD composites prepared with Si69 added during batch mixing. However, SMGD with high silane graft density does not permit SBR intercalation and produces composites with inferior mechanical properties, demonstrating the necessity of silane‐mediated interlayer grafting. Omitting Si69 from the formulation dramatically reduces the level of mechanical reinforcement as measured by DMA and tensile testing. Adding extra bulk sulfur (to replace sulfur omitted with Si69) does not produce composites with mechanical properties comparable to CMGD/SBR or SMGD/SBR prepared with Si69. This work demonstrates that silane‐mediated SBR‐MGD grafts within the MGD interlayer space are essential for achieving high levels of mechanical reinforcement in MGD/SBR composites. © 2017 Wiley Periodicals, Inc.

Computer simulation study of images in contact and near‐contact printing (1974)

Abstract Versatile computer programs capable of simulating near‐contact images from arbitrary objects and illumination were reported. Their capability was demonstrated in examples of combinations of different types of object and illumination. From the specific examples, we were able to derive certain general rules: (1) Polychromatic illumination is always better than monochromatic illumination. (Besides observing the examples given above, polychromatic illumination also helps when standing waves in photoresist are considered.) (2) Negative masks are easier to print than positive ones. Note that a negative mask in the sense of optical diffraction means smaller dimension for transparent parts of the mask. (3) Some well designed irregularities in the mask pattern improves the image. (4) The effective depth tolerance is between the limits set by the focussing effect and the image spreading effect. (5) Holographic mask should relax flatness and exposure tolerance.

Learning Image Descriptors with the Boosting-Trick (2012)

In this paper we apply boosting to learn complex non-linear local visual feature representations, drawing inspiration from its successful application to visual ob-ject detection. The main goal of local feature descriptors is to distinctively repre-sent a salient image region while remaining invariant to viewpoint and illumina-tion changes. This representation can be improved using machine learning, how-ever, past approaches have been mostly limited to learning linear feature mappings in either the original input or a kernelized input feature space. While kernelized methods have proven somewhat effective for learning non-linear local feature de-scriptors, they rely heavily on the choice of an appropriate kernel function whose selection is often difficult and non-intuitive. We propose to use the boosting-trick to obtain a non-linear mapping of the input to a high-dimensional feature space. The non-linear feature mapping obtained with the boosting-trick is highly intu-itive. We employ gradient-based weak learners resulting in a learned descriptor that closely resembles the well-known SIFT. As demonstrated in our experiments, the resulting descriptor can be learned directly from intensity patches achieving state-of-the-art performance. 1
Lignin–Inorganic Interfaces: Chemistry and Applications from Adsorbents to Catalysts and Energy Storage Materials (2020)

Lignin is one the most fascinating natural polymers due to its complex aromatic-aliphatic structure. Phenolic hydroxyl and carboxyl groups along with other functional groups provide technical lignins with reactivity and amphiphilic character. Many different lignins have been used as functional agents to facilitate the synthesis and stabilization of inorganic materials. Herein, the use of lignin in the synthesis and chemistry of inorganic materials in selected applications with relevance to sustainable energy and environmental fields is reviewed. In essence, the combination of lignin and inorganic materials creates an interface between soft and hard materials. In many cases it is either this interface or the external lignin surface that provides functionality to the hybrid and composite materials. This Minireview closes with an overview on future directions for this research field that bridges inorganic and lignin materials for a more sustainable future.

H<sub>&#x221E;</sub> loop shaping control for distributed PLL network (2009)

In this paper, we describe a robust control law for distributed PLL network using H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> optimization problem. The controller can be uniformly applied on all distributed nodes and guarantees good stability margins, enhanced performance and reduced jitter noise. A 2-dimensional Cartesian mesh network structure is considered without using any feedback loop phase information propagation to eliminate undesirable mode-locked states.
Novel Adrenoceptor Antagonists with a Tricyclic Pyrrolodipyridazine Skeleton (1998)

A still unknown tricyclic heterocyclic system (5) was synthesized from 6-hydroxy-2-methylpyridazin-3-one and its structure identified as 2,8-dichloro-6-methylpyrrolo[1,2-b:3,4-d']dipyridazin-5(6H)- one by spectroscopic investigations. Selective condensation of 5 with 2-[4-(2-substituted-phenyl)piperazin-1-yl]ethylamine gave the 2-arylpiperazinylethylamino-8-chloro derivatives 6a-c, which were investigated in binding studies toward the three alpha1-adrenergic and 5-HT1A-serotonergic receptor subtypes. They displayed high potency on all the assays and some selectivity for alpha1a and alpha1d subtypes.
A Study Toward Minimum Spatial Discretization of a Fuel Cell Dynamics Model (2006)

The 24-state fuel cell water dynamics model from [1] is cast into a Dymola™ icon-based formulation, with flexible library sub-models specific for this application. Through and across (flow and effort in bond graph terminology) variables are identified and analyzed for all relevant energy-using components. The objective is to establish the necessary model order for the fuel cell model using an energy-based measure called activity [2]. Additionally, we analyze the effect that input variation (duration, initial/final time) has on calculation and implementation of the activity. Explanation of the importance of accurate water vapor concentration gradient modeling is covered. Finally, we show that the minimum degree of discretization for each constituent within the model should be determined separately in order to generate the simplest model representation, and that the optimal discretization can be different for each species.
Farming practices and the respiratory health risks of swine confinement buildings (2000)

This study investigated whether clean swine confinement buildings (SCB) are less harmful to the respiratory system than older and dirtier facilities. Eight healthy volunteers were exposed for 4 h, at 1 week intervals, to eight SCB representing the widest possible range of cleanliness. Each volunteer and a technician rated the SCB for cleanliness from 1-10, 1 being the cleanest possible. Airborne dust, bacteria, endotoxin levels, molds, and ammonia were measured. For each volunteer measured, before and after each exposure, forced expiratory flows (forced expiratory volume in one second (FEV1), and forced vital capacity), white cells in nasal wash and venous blood, and nasal lavage levels of interleukin (IL)-8 and serum levels of IL-6. A methacholine challenge was obtained at baseline and following each exposure. Cleanliness scores ranged 1.5-8.25. Mean airborne levels were: dust 3.54 mg x m(-3) bacteria 4.25 x 10(5) CFU x m(-3); endotoxins 404 EU x m(-3); molds 883 CFU x m(-3); ammonia 20.7 parts per million (ppm). Expiratory flows decreased after exposure (FEV1 from 4.8+/-0.7 to 4.4+/-0.7, p<0.001), neutrophils in the nasal wash and white blood cells increased (28.5+/-37 to 424+/-207 x 10(3), 5.4+/-1.0 to 7.4+/-1.7 x 10(9) cells x mL(-1) respectively), IL-8 increased from 158+/-311 to 2679+/-639 pg x mL(-1), IL-6 from 0.15+/-0.26 to 2.34+/-0.92 pg x mL(-1), (p<0.001). All SCB were similarly harmful. In conclusion, modern farming has not succeeded in making swine confinement buildings inoffensive to exposed subjects.
Estimation of propagation speed during ventricular fibrillation from frequency-wavenumber power spectra (2002)

Propagation speed during ventricular fibrillation (VF) in pigs was estimated from the frequency-wavenumber power spectrum of epicardial mapping data. Data from a 22/spl times/23 array of epicardial electrodes were analyzed to obtain power as a function of wavenumber (spatial frequency). Temporal power spectra were found at each of 10 dominant wavenumbers. Wave speed (in units of mm/s) was estimated from a weighted average of temporal frequency (units of 1/s) divided by wavenumber magnitude (units of 1/mm). Speeds were estimated using data from simulations, sinus rhythm, and early VF. The effect of propranolol on conduction speed during VF was also investigated. The proposed method is useful for analyzing VF, when the existence of many incoherent wave fronts makes if difficult to measure wave speed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Structural and magnetic characterization of the lithiated iron oxide LixFe3O4 (1986)

The Rietveld profile-analysis method is used to investigate the x-ray diffraction pattern of lithiated Fe3O4. It is shown that, after exposure to air, pure magnetite coexists with a lithium-inserted LixFe3O4 phase. The Mössbauer spectra at 300 and 4.2 K have been used to estimate the lithium content of the sample, the pure magnetite concentration, and the iron distribution over the available 16c and 16d sites of the spinel structure. Magnetization measurements from 4.2 to 120 K with an external magnetic field up to 150 kOe have been used to obtain the saturation magnetic moment, the magnetic anisotropy constants, and the susceptibility. It is concluded that a noncollinear spin structure should be present in Li0.5Fe3O4. These results indicate that there is no room-temperature extrusion of iron even for x→2.0, but that on exposure to air LixFe3O4 samples with x&amp;gt;0.5 are oxidized at room temperature by delithiation.
Channel Dynamics and SNR Tracking in Millimeter Wave Cellular Systems (2016)

The millimeter wave (mmWave) frequencies are likely to play a significant role in fifth-generation (5G) cellular systems. A key challenge in developing systems in these bands is the potential for rapid channel dynamics: since mmWave signals are blocked by many materials, small changes in the position or orientation of the handset relative to objects in the environment can cause large swings in the channel quality. This paper addresses the issue of tracking the signal to noise ratio (SNR), which is an essential procedure for rate prediction, handover and radio link failure detection. A simple method for estimating the SNR from periodic synchronization signals is considered. The method is then evaluated using real experiments in common blockage scenarios combined with outdoor statistical models.
