Mobiscan3D: A Low Cost Framework for Real Time Dense 3D Reconstruction on Mobile Devices (2014)

In this paper we propose a computationally inexpensive framework for dense 3D reconstruction on smart device platforms leveraging the feed from motion sensors. In contrast to other methods, we solely rely on the motion sensors to compute pair wise epipolar relationships. In particular, camera positions are obtained only through noisy mobile sensor data which is further optimized globally using iterative reweighted least squares. Rotations are also obtained using mobile sensors. Our method of obtaining camera motion reduce the processing time of the entire pipeline. We further use pair wise epipolar relationships along with normalized cross correlation and gradient information in a pair of images to obtain dense correspondences. The calibrations and correspondences are accurate enough for triangulation which in turn serve as a good initializer for final global bundle adjustment in near real time. Experimental results show that our method works reliably well for both indoor and outdoor scenes of different size and shapes without even utilizing mobile GPU.
Profiling of RNAi sensitivity after foliar dsRNA exposure in different European populations of Colorado potato beetle reveals a robust response with minor variability (2020)

In recent years, substantial effort was spent on the exploration and implementation of RNAi technology using double-stranded RNA (dsRNA) for pest management purposes. However, only few studies investigated the geographical variation in RNAi sensitivity present in field-collected populations of the targeted insect pest. In this baseline study, 2nd instar larvae of 14 different European populations of Colorado potato beetle (CPB), Leptinotarsa decemlineata, collected from nine different countries were exposed to a foliarly applied diagnostic dose of dsactin (dsact) to test for possible variations in RNAi response. Only minor variability in RNAi sensitivity was observed between populations. However, the time necessary to trigger a dsRNA-mediated phenotypic response varied significantly among populations, indicated by significant differences in mortality figures obtained five days after treatment. An inbred German laboratory reference strain D01 and a Spanish field strain E02 showed almost 100% mortality after foliar exposure to 30 ng dsactin (equal to 0.96 g/ha), whereas another Spanish strain E01 was least responsive and showed only 30% mortality. Calculated LD<sub>50</sub>-values for foliarly applied dsact against strains D01 (most sensitive) and E01 (least sensitive) were 9.22 and 68.7 ng/leaf disc, respectively. The variability was not based on target gene sequence divergence or knock-down efficiency. Variability in expression of the core RNAi machinery genes dicer (dcr2a) and argonaute (ago2a) was observed but did not correlate with sensitivity. Interestingly, RT-qPCR data collected for all strains revealed a strong correlation between the expression level of dcr2a and ago2a (r 0.93) as well as ago2a and stauC (r 0.94), a recently described dsRNA binding protein in Coleopterans. Overall, this study demonstrates that sensitivity of CPB to sprayable RNAi slightly varies between strains but also shows that foliar RNAi as a control method works against all tested CPB populations collected across a broad geographic range in Europe. Thus, underpinning the potential of RNAi-based CPB control as a promising component in integrated pest management (IPM) and resistance management programs.
Controlling Liquid Crystal Orientations for Programmable Anisotropic Transformations in Cellular Microstructures (2021)

Geometric reconfigurations in cellular structures have recently been exploited to realize adaptive materials with applications in mechanics, optics, and electronics. However, the achievable symmetry breakings and corresponding types of deformation and related functionalities have remained rather limited, mostly due to the fact that the macroscopic geometry of the structures is generally co-aligned with the molecular anisotropy of the constituent material. To address this limitation, cellular microstructures are fabricated out of liquid crystalline elastomers (LCEs) with an arbitrary, user-defined liquid crystal (LC) mesogen orientation encrypted by a weak magnetic field. This platform enables anisotropy to be programmed independently at the molecular and structural levels and the realization of unprecedented director-determined symmetry breakings in cellular materials, which are demonstrated by both finite element analyses and experiments. It is illustrated that the resulting mechanical reconfigurations can be harnessed to program microcellular materials with switchable and direction-dependent frictional properties and further exploit "area-specific" deformation patterns to locally modulate transmitted light and precisely guide object movement. As such, the work provides a clear route to decouple anisotropy at the materials level from the directionality of the macroscopic cellular structure, which may lead to a new generation of smart and adaptive materials and devices.
Modeling Vibrations of a Tiled Talbot-Lau Interferometer on a Clinical CT (2022)

X-ray computed tomography (CT) is an invaluable imaging technique for non-invasive medical diagnosis. However, for soft tissue in the human body the difference in attenuation is inherently small. Grating-based X-ray phase-contrast is a relatively novel imaging method which detects additional interaction mechanisms between photons and matter, namely refraction and small-angle scattering, to generate additional images with different contrast. The experimental setup involves a Talbot-Lau interferometer whose susceptibility to mechanical vibrations hindered acquisition schemes suitable for clinical routine in the past. We present a processing pipeline to identify spatially and temporally variable fluctuations occurring in an interferometer installed on a continuously rotating clinical CT gantry. The correlations of the vibrations in the modular grating setup are exploited to identify a small number of relevant fluctuation modes, allowing for a sample reconstruction free of vibration artifacts.
Cell damage induced by Angiovist‐370 and 308nm excimer laser radiation (1997)

Background and Objective Radiographic contrast media containing iodine-labeled organic compounds can be present in the irradiated field during laser angioplasty using 308 nm excimer laser radiation. These compounds absorb light at 308 nm and may undergo photochemical reactions that produce products that damage cells. Study Design/Materials and Methods This study was undertaken to determine whether photoproducts that damage human lymphocytes in vitro are formed when Angiovist 370 (AV), a contrast medium containing triiodinated aromatic compounds, is exposed to 308 nm radiation. Results The absorption spectrum of AV developed a new peak at 360 nm that extended to wavelengths greater than 500 nm when dilute AV solutions were exposed to 308 nm radiation indicating that photoproducts were formed. Irradiating dilute AV solutions above a layer of human lymphocytes caused a dose-dependent decrease in thymidine incorporation using fluence rates between 5.2 × 106 and 1.0 × 108 W/cm2. Decreased DNA synthesis was independent of the pulse length (10 ns vs. 230 ns) but was lower, at a given dose, when the highest fluence rate was used. Incubation of lymphocytes with preirradiated AV solutions also decreased incorporation of thymidine in a radiation dose-dependent manner. The cell damaging photoproducts in preirradiated AV solutions were unstable; within 15 min, the effectiveness had decreased by ∼85%. Conclusions These results indicate that exposure of AV to 308 nm excimer laser radiation produces photochemical products that damage human cells in vitro. Lasers Surg.

Improved survival in patients with primary sclerosing cholangitis and normalization of serum cholestasis markers after biliary dilatation therapy (2015)

Primary sclerosing cholangitis (PSC) is aggravated by dominant stenosis of the large bile ducts (DS) in the majority of cases. PSC patients with concomitant DS require endoscopic dilatation therapy to resolve biliary obstruction, but survival still remains impaired. We aimed to analyze the advantage of serum cholestatic markers to predict dilatation- and transplantation-free survival in PSC patients after endoscopic therapy.

Data from Genetic Instability Caused by Loss of MutS Homologue 3 in Human Colorectal Cancer (2023)

&lt;div&gt;Abstract&lt;p&gt;Microsatellite instability (MSI) is a hallmark of mismatch repair (MMR) deficiency. High levels of MSI at mononucleotide and dinucleotide repeats in colorectal cancer (CRC) are attributed to inactivation of the MMR genes, &lt;i&gt;hMLH1&lt;/i&gt; and &lt;i&gt;hMSH2&lt;/i&gt;. CRC with low levels of MSI (MSI-L) exists; however, its molecular basis is unclear. There is another type of MSI—elevated microsatellite alterations at selected tetranucleotide repeats (EMAST)—where loci containing [AAAG]&lt;sub&gt;n&lt;/sub&gt; or [ATAG]&lt;sub&gt;n&lt;/sub&gt; repeats are unstable. EMAST is frequent in non-CRCs; however, the incidence of EMAST and its cause in CRC is not known. Here, we report that MutS homologue 3 (MSH3) knockdown or MSH3-deficient cells exhibit the EMAST phenotype and low levels of mutations at dinucleotide repeats. About 60% of 117 sporadic CRC cases exhibit EMAST. All of the cases defined as MSI-H (16 cases) exhibited high levels of EMAST. Among 101 non–MSI-H cases, all 19 cases of MSI-L and 35 of 82 cases of MSS exhibited EMAST. Although non–MSI-H CRC tissues contained MSH3-negative tumor cells ranging from 2% to 50% of the total tumor cell population, the tissues exhibiting EMAST contained more MSH3-negative cells (average, 31.5%) than did the tissues not exhibiting EMAST (8.4%). Taken together, our results support the concept that MSH3 deficiency causes EMAST or EMAST with low levels of MSI at loci with dinucleotide repeats in CRC.

A 320 x 240pixel uncooled TEC-less infrared radiation focal plane array with the reset noise canceling algorithm (2010)

We have developed a 22um pitch and 320 × 240 pixel uncooled infrared radiation focal plane array on the silicon-oninsulator (SOI) substrate by means of 0.35um CMOS technology and bulk-micromachining. For IR detection, we use silicon single-crystal series p-n junctions that can realize high uniformity of sensitivity and low voltage drift. The supporting beam shrinkage enabled the pixel pitch shrinkage from 32um to 22um and 320 × 240 pixel number without deteriorating NETD. We also developed a SOI low-noise CMOS readout circuit that can calibrate chip temperature and introduced a noise canceling digital algorithm to cancel the reset noise generated in the readout circuit. The dominant noise source, SOI MOSFET noise, was decreased by optimizing the gate design. Finally the FPA has realized noise equivalent temperature difference (NETD) of 0.12K and requires no thermo-electric cooler (TEC) and is mounted on a low-cost standard ceramic package.
Biology of LOX-1 in relation to atherogenesis (2008)

LOX-1, a lectin-like 52 kD receptor for oxidized LDL, is present primarily onendothelial cells. It has been linked to endothelial dysfunction, inflammation andoxidative stress. LOX-1 activation has also been linked to collagen formation, akey component of atherosclerotic lesion formation. Recent studies in mousemodels of hyperlipidemia and atherosclerosis demonstrate that deletion of LOX-1sustains endothelial function and inhibits inflammation and oxidative stress,resulting in a marked reduction in the formation of atherosclerotic plaques. Earlystudies demonstrate that LOX-1 abrogation also reduces collagen deposition inatherosclerotic lesions. This review highlights recent findings on the role of LOX-1in the modulation of atherosclerosis and collagen accumulation in theatherosclerotic plaques.
Ambient Temperature Hydrophosphination of Internal, Unactivated Alkynes and Allenyl Phosphineoxides with Phosphine Borane Complexes (2009)

Phosphine boranes have been found to hydrophosphinate internal, unactivated alkynes at room temperature under basic conditions without the need for catalysts or radical initiators. The use of air-sensitive secondary phosphines is avoided in this facile process. Broad scope in both the phosphine borane and alkyne partners leads to excellent diversity in the phosphine products. Asymmetric hydrogenation of these species then provides one of the shortest possible routes to chiral monodentate phosphines. Hydrophosphination of allenyl phosphine oxides under similar conditions followed by hydrogenation of the exomethylene moiety yields a wide variety of bis-phosphine derivatives.
Beta‐blocker‐associated hypoglycaemia: New insights from a real‐world pharmacovigilance study (2021)

Nadolol appears to be the β-blocker significantly most associated with hypoglycaemia and children represent the most susceptible sample. Furthermore, long half-life and nonselective β-blockers seem to increase the risk for its occurrence.
Infliximab for the Treatment of Orofacial Crohn's Disease (2001)

Orofacial manifestations of Crohn's disease can be difficult to diagnose and treat. We report a case in which the orofacial lesions occurred 7 years prior to the diagnosis of underlying inflammatory bowel disease. The patient was refractory to mesalamine and systemic corticosteroids but responded to infliximab, the chimeric monoclonal antibody to tumor necrosis factor (TNF-alpha). A review of the literature of the orofacial granulomatoses is presented as well.

Selective Peripheral Chemoreceptor Hyperreflexia Evoked after Sympathetic Stimulation (2020)

Previous studies have demonstrated that the integrity of the carotid bodies is essential for the development and maintenance of hypertension. In this condition, both increased tonicity and hyperreflexia are displayed by chemosensitive neurons in the petrosal ganglia of spontaneous hypertensive rats (SHR). However, what drives carotid body hyper‐excitability is not known. We hypothesised this was triggered by the sympathetic nerves innervating the carotid body, which originate from the superior cervical ganglion (SCG). The aim of our study was test if activation of the SCG could modulate carotid body activity. Experiments were carried out in 6 juvenile Wistar rats (60–80g) using the decerebrated in situ working heart‐brainstem preparation (WHBP). Simultaneous recordings of phrenic (PN) and thoracic sympathetic nerves (tSNA) were obtained using glass suction electrodes. Heart rate (HR) was derived from the electrocardiogram (ECG). Chemoreflex was activated using NaCN (50μL, 0.04%, i.a.) and the SCG was stimulated electrically (ES; 30Hz, 2 ms, 10V) using a Grass SD9 stimulator via a bipolar microelectrode. The chemoreflex was evoked before and immediately after ES of the SCG. Changes in sympathetic activity, perfusion pressure, phrenic and heart rate were analysed quantitatively. Data are displayed as mean ± SEM with a level of significance set at P&lt;0.05; differences were tested using paired student‐t test. The only component of the chemoreflex augmented by SCG stimulation was the evoked increase in sympathetic activity. In Wistars, the control response of 29.3 ± 3.2% from baseline was augmented to 46.04 ± 3.58% after ES (P=0.006). Within 10 min of the stimulation, the sympatho hyperreflexia had returned to control (20.24 ± 5.96%). SHR also presented sympatho hyperreflexia (43.0 ± 6.3 vs 62.9 ± 9.2 %, P= 0.015) but the change of sensitization was of similar magnitude between rat strains. The SCG induced carotid body hyperreflexia was prevented by application of lignocaine into the SCG. We conclude that stimulation of the efferent sympathetic nerves innervating the carotid body can increase the gain of the chemoreflex symathoexcitatory response. We are currently assessing whether chemoreflex hyperreflexia observed in neurogenic hypertension is mediated by sympathetic nerves innervating the carotid body.

Electron Transfer and Electronic Conduction through an Intervening Medium (2008)

A new vision for ET: Electron-transfer (ET) processes in biological and synthetic materials (such as proteins and semiconductors, respectively) are of immense importance. A unified approach to describe these processes is useful in understanding, and controlling the various facets of electron transfer in condensed matter. The diagram shows a plot of the decay constant for the electron-tunneling process against the effective tunneling barrier in different materials.
Prefrontal and parietal regions are involved in naming of objects seen from unusual viewpoints. (2007)

Object naming is commonly used for demonstrating semantic memory abilities, known to be affected in normal aging. Yet, neuropsychological assessments of older people do not reflect irregularities. The authors used a test with 2 levels of naming complexity by 2 kinds of stimuli: common objects pictured from a conventional viewpoint (usual condition) or from an unconventional viewpoint (unusual condition). The authors studied naming performance with 129 healthy participants, aged 20-85 years. For the usual stimuli, the success rate was high (90.9%), with no reduction in performance until 65 years of age. However, for the unusual stimuli, there was a marked reduction in performance with age. Brain activity was studied on 11 healthy young participants (20-30 years of age) using functional magnetic resonance imaging. The usual condition activated brain regions associated with visual perception, language, and memory. Additional brain regions associated with semantic searching and decision making were obtained in the unusual condition in the prefrontal cortex (Brodmann's area [BA] 9 and BA 47) and anterior cingulate (BA 32). The results suggest that the poor naming performance for unusual-viewed objects in older people might be related to the shrinkage of frontal gray matter with age.
Frame timing acquisition for direct sequence spread spectrum signals in time division duplex transmission (2002)

The frame timing acquisition, which is important for the time division duplex (TDD) mode of transmission in direct sequence spread spectrum (DS-SS) communications, is studied. In the TDD-DS-SS system, the frame timing and base station signal must be obtained in the presence of interference from other mobile users. It is shown that acquisition of noncontinuous TDD signals is possible after transmission of a few acquisition bursts. Computer simulation techniques are used to evaluate the performance of this method.

Construction of Ti-Al-Cr Phase Diagram Using Quantitative X-ray Microanalysis in Analytical Electron Microscope (2001)

This paper describes determination of the Ti-Al-Cr ternary phase diagrams using quantitative X-ray microanalysis in analytical electron microscopy. Alloys with several different compositions were subjected to heat treatments for equilibration at 1273 and 1473 K. Microstructural observations and selected area electron diffraction analyses were conducted for phase identification and characteristic X-rays were measured from each phase. The characteristic X-ray intensities were then converted to concentrations using the ζ-factor method while the absorption correction was simultaneously achieved with this method.It was found that the three-phase regions such as α2+B2+γ, B2+γ+Laves and γ+Laves+L12 were present at 1273 K, whereas at 1473 K, no Laves phase was observed and disordering occurred from the α2 and B2 phases to the α and β phases, respectively. Thus, the three-phase regions were present as α+β+γ and β+γ+L12 at 1473 K. The α+β+γ and β+γ regions were extended to a lower Al concentration as the temperature decreases.

Analysis of the 3' flanking region of the human c-myc gene in lymphomas with the t(8;22) and t(2;8) chromosomal translocations (1986)

We have cloned and mapped the sequences extending 38 kb 3' of the c-myc gene. This region is found to be highly repetitive in nature and hybridizes extensively with a BLUR 8 Alu probe. Unique sequence probes derived from this region were used to map the chromosomal breakpoints of a number of lymphoma cell lines with t(2;8) or t(8;22) translocations. In five of the cell lines (PA682, LY67, LY47, LY66 and LY91), the immunoglobulin light chain locus translocates into a region which is greater than 47 kb downstream of c-myc. For one of the cell lines, JI, the location of the breakpoint on the 8q+ chromosome was found to be 25-32 kb 3' of c-myc. The breakpoint for the BL2 cell line had been previously mapped at 10 kb 3' of the c-myc oncogene. Analyses of steady-state levels of c-myc mRNA in cell lines with chromosomal breakpoints ranging from 10 kb to greater than 47 kb 3' of c-myc range from 0.5 to 10X the levels in lymphoblast controls. The different levels of c-myc transcripts is not a direct function of the distance between the c-myc gene and the translocated immunoglobulin light chain locus.
