Search for narrow resonances using the dijet mass spectrum inppcollisions ats=8  TeV (2013)

Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$. The data sample corresponds to an integrated luminosity of $4.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall--Sundrum graviton model in the dijet channel.
Microbial Production ofL-Ascorbic Acid fromD-Sorbitol,L-Sorbose,L-Gulose, andL-Sorbosone byKetogulonicigenium vulgareDSM 4025 (2005)

Ketogulonicigenium vulgare DSM 4025, known as a 2-keto-L-gulonic acid producing strain from L-sorbose via L-sorbosone, surprisingly produced L-ascorbic acid from D-sorbitol, L-sorbose, L-gulose, and L-sorbosone as the substrate under a growing or resting condition. As the best result, K. vulgare DSM 4025 produced 1.37 g per liter of L-AA from 5.00 g per liter of L-sorbosone during 4 h incubation time at 30 degrees C under the resting cell condition having 5.70 g per liter of wet cells. The precursor of L-AA formation from D-sorbitol and L-sorbose, except for L-gulose, was thought to be the putative furanose form of L-sorbosone. This is the first time it is reported that bacteria can produce vitamin C via L-sorbosone.

Hybrid silicon-electro-optic-polymer integrated high-performance optical modulator (2014)

We design and demonstrate a compact and low-power band-engineered electro-optic (EO) polymer refilled silicon slot photonic crystal waveguide (PCW) modulator. The EO polymer is engineered for large EO activity and nearinfrared transparency. A PCW step coupler is used for optimum coupling to the slow-light mode of the bandengineered PCW. The half-wave switching-voltage is measured to be V<sub>&pi;</sub>=0.97&plusmn;0.02V over optical spectrum range of 8nm, corresponding to the effective in-device r<sub>33</sub> of 1190pm/V and V<sub>&pi;</sub>&times;L of 0.291&plusmn;0.006V&times;mm in a push-pull configuration. Excluding the slow-light effect, we estimate the EO polymer is poled with an efficiency of 89pm/V in the slot.

High-Performance Tunable Narrowband SIW Cavity-Based Quadrature Hybrid Coupler (2018)

This letter presents, for the first time, a tunable narrowband substrate integrated waveguide (SIW) cavity-based quadrature hybrid coupler. Four high-quality factor (Q) SIW evanescent-mode cavity resonators are employed in the design and tuned using piezoelectric actuators. This allows the proposed coupler to have wide spurious-free range (SFR), low-power consumption, and high-power handling capability compared to other tunable planar couplers. The coupler can be tuned starting from 1.32 to 2.22 GHz with a measured insertion loss range from 1.29 to 0.7 dB. Over the full range, the measured 3-dB fractional bandwidth ranges from 5% to 18% while the measured ±5° phase error (LS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> - LS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">31</sub> ) absolute bandwidth ranges from 40 to 82 MHz with an amplitude imbalance range between 1 and 0.3 dB. The measured reflection and isolation are better than 12 and 17 dB, respectively. Moreover, the coupler has a measured SFR of 5.1-3 f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">o</sub> (lowest-highest frequency).
Cavitation bubble generation and control for HIFU transcranial adaptive focusing (2009)

Brain treatment with High Intensity Focused Ultrasound (HIFU) can be achieved by multichannel arrays through the skull using time‐reversal focusing. Such a method requires a reference signal either sent by a real source embedded in brain tissues or computed from a virtual source, using the acoustic properties of the skull deduced from CT images. This noninvasive computational method allows precise focusing, but is time consuming and suffers from unavoidable modeling errors which reduce the accessible acoustic pressure at the focus in comparison with real experimental time‐reversal using an implanted hydrophone. Ex vivo simulations with a half skull immersed in a water tank allow us to reach at low amplitude levels a pressure ratio of 83% of the reference pressure (real time reversal) at 1MHz. Using this method to transcranially focus a pulse signal in an agar gel (model for in vivo bubble formation), we induced a cavitation bubble that generated an ultrasonic wave received by the array. Selecting the 1MHz component, the signal was time reversed and re‐emitted, allowing 97%±1.1% of pressure ratio to be restored. To target points in the vicinity of the geometrical focus, electronic steering from the reference signal has been achieved. Skull aberrations severely degrade the accessible pressure while moving away from the focus ( ∼90% at 10mm in the focal plane). Nevertheless, inducing cavitation bubbles close to the limit of the primary accessible zone allowed us to acquire multiple references signal to increase the electronic steering area by 50%.

Coexistence possibilities of LTE with ISM technologies and GNSS (2011)

Interference due to in-device coexistence of multiple radios operating simultaneously in adjacent or overlapping radio frequency spectrum is a big issue. In this article, we understand the nature of issues related to coexistence of LTE with ISM technologies (Bluetooth, WiFi) and GNSS in a mobile handset. Each of these technologies have different characteristics such as different access mechanism, frame structure, peak transmit power and operate in different frequencies. We analyze the charecteristics of each technology and propose possible direction so that in-device coexistence interference for certain popular use cases can be mitigated.
Croquemort elicits activation of the immune deficiency pathway in ticks (2023)

The immune deficiency (IMD) pathway directs host defense in arthropods upon bacterial infection. In Pancrustacea, peptidoglycan recognition proteins sense microbial moieties and initiate nuclear factor-κB-driven immune responses. Proteins that elicit the IMD pathway in non-insect arthropods remain elusive. Here, we show that an <i>Ixodes scapularis</i> homolog of croquemort (Crq), a CD36-like protein, promotes activation of the tick IMD pathway. Crq exhibits plasma membrane localization and binds the lipid agonist 1-palmitoyl-2-oleoyl-<i>sn</i>-glycero-3-phosphoglycerol. Crq regulates the IMD and jun N-terminal kinase signaling cascades and limits the acquisition of the Lyme disease spirochete <i>B. burgdorferi</i>. Additionally, nymphs silenced for <i>crq</i> display impaired feeding and delayed molting to adulthood due to a deficiency in ecdysteroid synthesis. Collectively, we establish a distinct mechanism for arthropod immunity outside of insects and crustaceans.
[Amebic colitis - differential diagnosis of ulcerative colitis and Crohn disease]. (1984)

Amoebic colitis rarely develops in patients who had not stayed in a country where amoebiasis is endemic. "Crohn's colitis" was diagnosed in a 33 year old female patient who never had stayed in such an area. The dramatic deterioration of the disease led to revise the early diagnosis. The reported case indicates that the conventional laboratory, endoscopic, histologic, and radiologic examinations don't prove the anamnestically unsuspected amoebic colitis. Since the correct diagnosis was verified by stool and serologic examinations, these should be performed in any doubt of a specific colitis.
Isolation of single-walled carbon nanotube enantiomers by density differentiation (2009)

Current methods of synthesizing single-walled carbon nanotubes (SWNTs) result in racemic mixtures that have impeded the study of left- and right-handed SWNTs. Here we present a method of isolating different SWNT enantiomers using density gradient ultracentrifugation. Enantiomer separation is enabled by the chiral surfactant sodium cholate, which discriminates between left- and right-handed SWNTs and thus induces subtle differences in their buoyant densities. This sorting strategy can be employed for simultaneous enrichment by handedness and roll-up vector of SWNTs having diameters ranging from 0.7 to 1.5 nm. In addition, circular dichroism of enantiomer refined samples enables identification of high-energy optical transitions in SWNTs.

Tunable radio frequency photonics filter using a comb-based optical tapped delay line with an optical nonlinear multiplexer (2015)

A radio frequency (RF) photonic filter is experimentally demonstrated using an optical tapped delay line (TDL) based on an optical frequency comb and a periodically poled lithium niobate (PPLN) waveguide as multiplexer. The approach is used to implement RF filters with variable bandwidth, shape, and center-frequency.
Single tracking location acoustic radiation force impulse viscoelasticity estimation (STL-VE): A method for measuring tissue viscoelastic parameters (2015)

Single tracking location (STL) shear wave elasticity imaging (SWEI) is a method for detecting elastic differences between tissues. It has the advantage of intrinsic speckle bias suppression compared with multiple tracking location variants of SWEI. However, the assumption of a linear model leads to an overestimation of the shear modulus in viscoelastic media. A new reconstruction technique denoted single tracking location viscosity estimation (STL-VE) is introduced to correct for this overestimation. This technique utilizes the same raw data generated in STL-SWEI imaging. Here, the STL-VE technique is developed by way of a maximum likelihood estimation for general viscoelastic materials. The method is then implemented for the particular case of the Kelvin-Voigt Model. Using simulation data, the STL-VE technique is demonstrated and the performance of the estimator is characterized. Finally, the STL-VE method is used to estimate the viscoelastic parameters of ex vivo bovine liver. We find good agreement between the STL-VE results and the simulation parameters as well as between the liver shear wave data and the modeled data fit.
Analysis of Radius of Curvature of MEMS Optical Switch (2006)

Micro electro mechanical systems (MEMS) curved micromirror switch has the advantage of smaller size and lower cost. The radius of curvature of the micromirror is thus very important parameter. The effect of material properties and temperature on the curvature is analyzed in detail.
Integrated biomass hydropyrolysis and hydrotreating: a brief review (2014)

This article provides a brief overview of recent work connected with integrated hydropyrolysis and hydrotreating of biomass. It covers relevant aspects of biomass pyrolysis, and describes a process wherein oxygen is eliminated from pyrolysis vapors in the presence of hydrogen and appropriate catalysts. An integrated version of a process is discussed, wherein the reforming of noncondensable hydrocarbon vapors is used to generate all the hydrogen required to sustain hydropyrolysis and hydroconversion, and produce a deoxygenated liquid hydrocarbon fuel.

Iron overload in Hepc1−/− mice is not impairing glucose homeostasis (2007)

Diabetes Mellitus is found with increasing frequency in iron overload patients with hemochromatosis. In these conditions, the pancreas shows predominant iron overload in acini but also islet beta-cells. We assess glucose homeostasis status in iron-overloaded hepcidin-deficient mice. These mice presented with heavy pancreatic iron deposits but only in the acini. The beta-cell function was found unaffected with a normal production and secretion of insulin. The mutant mice were not diabetic, responded as the control group to glucose and insulin challenges, with no alteration of insulin signalling in the muscle and the liver. These results indicate that, beta-cells iron deposits-induced decreased insulin secretory capacity might be of primary importance to trigger diabetes in hemochromatosic patients.
Accurate Model of Saturated AMR Wheatstone Bridge Sensor Against a 48 Pole Pair Ring-Magnet. (2005)

Presented is a method to model a magnetoresistive Wheatstone bridge using a new magnetoresistive model for resistor elements in saturation. This new model accurately predicts the behavior of individual magnetoresistors and follows the form ∆R/R0=A+B((1+C*cos(2θ)2+C*sin(2θ)2). To demonstrate the use of this model, a 17.5nm thick permalloy sensor bridge was used to sense a forty-eight pole pair ring magnet. The results show a good correlation between the model and an actual device under test.
Characteristics of Debris from a CO<SUB>2</SUB> Laser-Produced Plasma Using a Solid Tin Target for Development of Extreme Ultraviolet Source (2007)

We have characterized CO2 laser generated debris from plane tin (Sn) targets with gold coated quartz crystal microbalances (QCM). Sputtering was the dominant process for 1mm and 15μm thick solid Sn targets. In addition, average conversion efficiency at 13.5nm of 2.0% within 2% full bandwidth and 2π sr solid angle was obtained. This indicates that a high CE without Sn debris deposition on a multi-layer collector mirror can be obtained.
Spectrum Management using Markov Decision Processes (2015)

Abstract: The advent of cognitive radio technology has enabled dramatically more options in the use of RF spectrum, allowing multiple transmitters to effectively share spectrum in ways that were previously unavailable (either due to technical limitations or regulatory restrictions). In this dissertation, we investigate approaches to managing RF spectrum use, with a focus on combining multiple control decisions in a mutually beneficial manner. Our approach to making spectrum management decisions is grounded in Markov decision theory, which has a rich formal foundation and is frequently used to guide decision making in other disciplines. Here, we develop a set of Markov Decision Processes (MDPs) that model the RF spectrum management problem (in various forms). These MDPs are then queried to provide guidance for management decisions, including the combination of both admission and modulation decisions. This results in control decisions that are optimal in expectation. To address the computational complexity inherent in computing these control decisions, we develop heuristic approaches that mimic the MDP's decisions based upon patterns observed in the MDP decision space. These heuristics are shown to closely approximate the optimal results from the MDP. Finally, we empirically assess the appropriateness of using Markov decision theory for RF spectrum management by comparing our MDPs to a discrete-event simulation model that relaxes several of the modeling assumptions made in the development of the MDPs.
Local dominant binary patterns for recognition of multi-view facial expressions (2016)

In this paper, a novel framework is proposed for automatic recognition of facial expressions. However, the face images for the proposed problem are captured at multiple view angle (i.e., multi-view facial expressions). The proposed scheme introduces a local dominant binary pattern (LDBP). Unlike uniform LBP based features, the LDBP uses fewer feature dimension without affecting the recognition performances. The LDBP is computed by improvising LBP with dominant orientations of neighborhood pixels. The eigen-value analysis of structure tensor representation of expressive face images determines the dominant directions of gray value changes in local neighbors of pixels. We use SVM for view-specific classification of multi-view facial expressions. The proposed model is experimented with the benchmark datasets of both near-frontal (CK+ and JAFEE) and multi-view (KDEF, SFEW and LFPW) face images. The datasets include faces from posed as well as spontaneous expressions. The proposed scheme outperforms state-of-the-arts by approximately 1% for the near-frontal facial expressions and by at least 3% for multi-view facial expressions on an average.
Method To Visualize the Intratumor Distribution and Impact of Gemcitabine in Pancreatic Ductal Adenocarcinoma by Multimodal Imaging (2022)

Gemcitabine (dFdC) is a common treatment for pancreatic cancer; however, it is thought that treatment may fail because tumor stroma prevents drug distribution to tumor cells. Gemcitabine is a pro-drug with active metabolites generated intracellularly; therefore, visualizing the distribution of parent drug as well as its metabolites is important. A multimodal imaging approach was developed using spatially coregistered mass spectrometry imaging (MSI), imaging mass cytometry (IMC), multiplex immunofluorescence microscopy (mIF), and hematoxylin and eosin (H&E) staining to assess the local distribution and metabolism of gemcitabine in tumors from a genetically engineered mouse model of pancreatic cancer (KPC) allowing for comparisons between effects in the tumor tissue and its microenvironment. Mass spectrometry imaging (MSI) enabled the visualization of the distribution of gemcitabine (100 mg/kg), its phosphorylated metabolites dFdCMP, dFdCDP and dFdCTP, and the inactive metabolite dFdU. Distribution was compared to small-molecule ATR inhibitor AZD6738 (25 mg/kg), which was codosed. Gemcitabine metabolites showed heterogeneous distribution within the tumor, which was different from the parent compound. The highest abundance of dFdCMP, dFdCDP, and dFdCTP correlated with distribution of endogenous AMP, ADP, and ATP in viable tumor cell regions, showing that gemcitabine active metabolites are reaching the tumor cell compartment, while AZD6738 was located to nonviable tumor regions. The method revealed that the generation of active, phosphorylated dFdC metabolites as well as treatment-induced DNA damage primarily correlated with sites of high proliferation in KPC PDAC tumor tissue, rather than sites of high parent drug abundance.
