Comparison of two different debonding techniques in orthodontic treatment (2017)

Microbiological data suggest that Herpesviruses are probably not mere spectators of disease progression and that specific patterns of subgingival plaque are correlated with the presence of different Herpesviruses.
Diffuse-light absorption spectroscopy for beer classification and prediction of alcoholic content (2012)

A miscellaneous of 86 beers was characterized by non-destructive, fast and reagent-free optical measurements. Diffuselight absorption spectroscopy performed in the visible and near-infrared bands was used to gather a turbidity-free spectroscopic information. Also, conventional turbidity and refractive index measurements were added for completing the optical characterization. The near-infrared spectra provided a straightforward turbidity-free assessment of the alcoholic strength. Then, the entire optical data set was processed by means of multivariate analysis looking for a beer clustering according to the own character and identity. Good results were achieved, indicating that optical methods can be successfully used for beer authentication.
Integrated source of broadband quadrature squeezed light (2015)

An integrated silicon nitride resonator is proposed as an ultra-compact source of bright single-mode quadrature squeezed light at 850 nm. Optical properties of the device are investigated and tailored through numerical simulations, with particular attention paid to loss associated with interfacing the device. An asymmetric double layer stack waveguide geometry with inverse vertical tapers is proposed for efficient and robust fibre-chip coupling, yielding a simulated total loss of -0.75 dB/facet. We assess the feasibility of the device through a full quantum noise analysis and derive the output squeezing spectrum for intra-cavity pump self-phase modulation. Subject to standard material loss and detection efficiencies, we find that the device holds promises for generating substantial quantum noise squeezing over a bandwidth exceeding 1 GHz. In the low-propagation loss regime, approximately -6 dB squeezing is predicted for a pump power of only 75 mW.
Application of periodically-poled LiNbO/sub 3/ for wide-bandwidth high-frequency electrooptic modulator (2001)

Summary form only given. Periodically-poled LiNbO/sub 3/ (PPLN) is an outstanding nonlinear optical material. Various PPLN-based frequency conversion devices have been developed. The piezoelectric and electrooptic (EO) effects of PPLN also have attracted more and more research attention. In this report, we show that a high-frequency, and wide bandwidth integrated EO modulator (EOM) can be achieved though quasi-velocity-matching (QVM) technique. Comparing with a conventional EOM with phase-reversed electrodes, the PPLN-based EOM has some advantages, e.g. the lower drive voltage and better stability Since PPLN is also a good nonlinear and piezoelectric crystal, it is possible to combine several functions in a PPLN wafer that is very attractive for modern opto-electronic Systems.

Bringing order to query optimization (2002)

A variety of developments combine to highlight the need for respecting order when manipulating relations. For example, new functionality is being added to SQL to support OLAP-style querying in which order is frequently an important aspect. The set- or multiset-based frameworks for query optimization that are currently being taught to database students are increasingly inadequate.This paper presents a foundation for query optimization that extends existing frameworks to also capture ordering. A list-based relational algebra is provided along with three progressively stronger types of algebraic equivalences, concrete query transformation rules that obey the different equivalences, and a procedure for determining which types of transformation rules are applicable for optimizing a query. The exposition follows the style chosen by many textbooks, making it relatively easy to teach this material in continuation of the material covered in the textbooks, and to integrate this material into the textbooks.
Fuchs’ corneal dystrophy (2010)

Fuchs' corneal dystrophy (FCD) is a progressive, hereditary disease of the cornea first described a century ago by the Austrian ophthalmologist Ernst Fuchs. Patients often present in the fifth to sixth decade of life with blurry morning vision that increases in duration as the disease progresses. Primarily a condition of the posterior cornea, characteristic features include the formation of focal excrescences of Descemet membrane termed 'guttae', loss of endothelial cell density and end-stage disease manifested by corneal edema and the formation of epithelial bullae. Recent advances in our understanding of the genetic and pathophysiological mechanisms of the disease, as well as the application of new imaging modalities and less invasive surgical procedures, present new opportunities for improved outcomes among patients with FCD.
Theorie II: Aus der Kurzmeldungsgeschichte (2005)

Meldungen begleiten nicht nur von Anfang an die Zeitungsgeschichte, lange Zeit waren sie die vorherrschende journalistische Darstellungsform: In einer Analyse der Wochenzeitungen Aviso (Wolfenbüttel) und Relation (Strassburg) aus dem Jahre 1609 - sie gelten als Ursprung der Tageszeitungen - kommt Schröder zu dem Ergebnis, dass die Meldungen im Schnitt 64 und 53 Worte zählten. „Die Mehrzahl aller Beiträge wäre also nach heutigem Maßstab unter der Rubrik Kurzmeldungen einzuordnen“ (Schröder 1995, 149).
Cerebral control of swallowing: An update on neurobehavioral evidence (2022)

This review aims to update the current knowledge on the cerebral control of swallowing. We review data from both animal and human studies spanning across the fields of neuroanatomy, neurophysiology and neuroimaging to evaluate advancements in our understanding in the brain's role in swallowing. Studies have collectively shown that swallowing is mediated by multiple distinct cortical and subcortical regions and that lesions to these regions can result in dysphagia. These regions are functionally connected in separate groups within and between the two hemispheres. While hemispheric dominance for swallowing has been reported in most human studies, the laterality is inconsistent across individuals. Moreover, there is a shift in activation location and laterality between swallowing preparation and execution, although such activation changes are less well-defined than that for limb motor control. Finally, we discussed recent neurostimulation treatments that may be beneficial for dysphagia after brain injury through promoting the reorganization of the swallowing neural network.

Computer-Assisted Spine Surgery (1998)

The aim of this study was to improve the reliability of pedicle screw insertion. Transpedicle screw insertion may cause neurological, vascular, and mechanical complications. Previous studies of surgical procedures have shown a significant rate of incorrect placement of the screw ranging from 10 to 40%A new technique that combines preoperative computed tomography (CT) imaging with intraoperative passive navigation was used to perform 64 pedicle screw insertions in the thoraco-lumbar region. At the same time, 64 pedicle screw insertions were performed manually in the same region and on the same vertebral levels. Surgery was followed in all cases by postoperative radiographs and computed tomography examination, which allowed measurements of screw position relative to pedicle position to be performedA comparison between the two groups showed that six screws in 64 vertebra (9%) had incorrect placement with the computer-assisted technique whereas 28 screws in 64 vertebra (44%) had incorrect placement with manual insertion. The intraoperative accuracy provided by the computer after registration was better than 1 mmThe good results obtained are similar to those reported in the literature. The cortex penetration observed with the computer-assisted technique was not imputed to computer failure. Errors by the surgeon in acquiring data in the pre- and perioperative steps may explain the six incorrect screw placementsThis clinical experience confirms that the accuracy and the reliability of this computer-assisted technique are good.
Keggin Ion Mediated Synthesis of Hydrophobized Pd Nanoparticles for Multifunctional Catalysis (2005)

Development of simple and reliable protocols for the synthesis of organically soluble catalytically active metal nanoparticles is an important aspect of research in nanomaterials. We demonstrate herein the formation of Pd nanoparticles by reduction of aqueous Pd(NO(3))(2) by photoexcited Keggin ions (phosphotungstate anions). This results in the formation of Pd nanoparticles capped with with Keggin ions that render the particles negatively charged. The Keggin ion capped Pd nanoparticles may then be phase transferred into nonpolar organic solvents such as toluene by electrostatic complexation with cationic surfactants such as octadecylamine at the liquid-liquid interface. This results in a new class of catalyst wherein both the Pd core and Keggin ion shell may be used in a range of catalytic reactions leading to a truly multifunctional catalyst dispersible in organic solvents.
Description of the low‐affinity interaction between nociceptin and the second extracellular loop of its receptor by fluorescence and NMR spectroscopies (2008)

The second extracellular loop (ECL2) of the Noc receptor has been proposed to be involved in ligand binding and selectivity. The interaction of Noc with a constrained cyclic synthetic peptide, mimicking the ECL2, has been studied using fluorescence and NMR spectroscopies. Selective binding was shown with a dissociation constant of approximately 10 microM (observed with the constrained cyclic loop and not with the open chain), and residues involved in ligand binding and selectivity have been identified. This bimolecular complex is stabilized by (i) ionic interactions between the two Noc basic motives and the ECL2 acidic residues; (ii) hydrophobic contacts involving Noc FGGF N-terminal sequence and an ECL2 tryptophane residue. Our data confirm that Noc receptor's ECL2 contributes actively to ligand binding and selectivity by providing the peptidic ligand with a low affinity-binding site.
Positive Regulation of Insulin Signaling by Neuraminidase 1 (2013)

Neuraminidases (sialidases) catalyze the removal of sialic acid residues from sialylated glycoconjugates. We now report that mammalian neuraminidase 1 (Neu1), in addition to its catabolic function in lysosomes, is transported to the cell surface where it is involved in the regulation of insulin signaling. Insulin binding to its receptor rapidly induces interaction of the receptor with Neu1, which hydrolyzes sialic acid residues in the glycan chains of the receptor and, consequently, induces its activation. Cells from sialidosis patients with a genetic deficiency of Neu1 show impairment of insulin-induced phosphorylation of downstream protein kinase AKT, and treatment of these cells with purified Neu1 restores signaling. Genetically modified mice with ∼10% of the normal Neu1 activity exposed to a high-fat diet develop hyperglycemia and insulin resistance twice as fast as their wild-type counterparts. Together, these studies identify Neu1 as a novel component of the signaling pathways of energy metabolism and glucose uptake.
Monitoring Implant Anneal by Non-Contact Room Temperature Photoluminescence (2012)

Arsenic ion (As+ 70 keV, 1.0 × 1015 cm−2) implanted p−-Si(100) samples were annealed under intense cw light from a Xe arc lamp. The arc lamp discharge power was fixed at 20 kW, and annealing time was varied from 0.1 to 2.2 s. Photoluminescence (PL) spectra from all samples were measured at room temperature under three different excitation wavelengths (532, 650 and 827 nm) and correlated with sheet resistance, measured using a four point probe, and As SIMS depth profiles. PL spectra measurements under 650 and 827 nm excitations are very promising as a non-contact, implant anneal monitoring technique.
Commutativity and Application of Digital Interpolation Filters and Modulators (1980)

Interpolation filters are being widely used in a variety of communication applications. An equivalent realization of an interpolation FIR filter is shown to be a cascade combination of a hold and a periodically varying filter. It is also shown that the periodicity of the filter results in the Commutativity of the filter and a sinusoidal modulator. An application of such a scheme to TDM-FDM transmultiplexer is also presented.

Unconstrained detection of freezing of Gait in Parkinson's disease patients using smartphone (2015)

Freezing of gait (FOG) is a common motor impairment to suffer an inability to walk, experienced by Parkinson's disease (PD) patients. FOG interferes with daily activities and increases fall risk, which can cause severe health problems. We propose a novel smartphone-based system to detect FOG symptoms in an unconstrained way. The feasibility of single device to sense gait characteristic was tested on the various body positions such as ankle, trouser pocket, waist and chest pocket. Using measured data from accelerometer and gyroscope in the smartphone, machine learning algorithm was applied to classify freezing episodes from normal walking. The performance of AdaBoost.M1 classifier showed the best sensitivity of 86% at the waist, 84% and 81% in the trouser pocket and at the ankle respectively, which is comparable to the results of previous studies.

15-deoxy-Δ12,14-PGJ2: endogenous PPARγ ligand or minor eicosanoid degradation product? (2003)

15-Deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2) affects gene transcription by activating PPARγ and by covalent addition to transcription factors and signaling molecules, However, it is not known whether the high concentrations of 15d-PGJ2 required for these responses are consistent with physiological levels. A new study suggests that in vivo 15d-PGJ2 levels are actually several orders of magnitude below the levels required to induce many of the biological effects attributed to this molecule.
SDViz: A Context‐Preserving Interactive Visualization System for Technical Diagrams (2009)

Abstract When performing daily maintenance and repair tasks, technicians require access to a variety of technical diagrams. As technicians trace components and diagrams from page‐to‐page, within and across manuals, the contextual information of the components they are analyzing can easily be lost. To overcome these issues, we have developed a Schematic Diagram Visualization System (SDViz) designed for maintaining and highlighting contextual information in technical documents, such as schematic and wiring diagrams. Our system incorporates various features to aid in the navigation and diagnosis of faults, as well as maintaining contextual information when tracing components/connections through multiple diagrams. System features include highlighting relationships between components and connectors, diagram annotation tools, the animation of flow through the system, a novel contextual blending method, and a variety of traditional focus+context visualization techniques. We have evaluated the usefulness of our system through a qualitative user study in which subjects utilized our system in diagnosing faults during a standard aircraft maintenance exercise.
Circulating Leptin in Patients with Chronic Obstructive Pulmonary Disease (1999)

Unexplained weight loss is common in patients with chronic obstructive pulmonary disease (COPD). Since leptin, an obesity gene product, is known to play important roles in the control of body weight and energy expenditure, we investigated serum leptin levels, along with circulating tumor necrosis factor-alpha (TNF-alpha) and soluble TNF receptor (sTNF-R55 and -R75) levels, in 31 patients with COPD and 15 age-matched healthy controls. The body mass index (BMI) and percent body fat (%fat) were significantly lower in the COPD patients than in the healthy controls (BMI = 18.1 +/- 2.7 kg/m2 versus 22.8 +/- 2.2 kg/m2 [mean +/- SD]; p < 0.0001; %fat = 16.9 +/- 5.8% versus 24.3 +/- 4.9%; p < 0.001). Serum leptin levels were significantly lower in the COPD patients than in the healthy controls (1.14 +/- 1.17 ng/ml versus 2.47 +/- 2.01 ng/ml; p < 0.05). In contrast, serum TNF-alpha levels (6.59 +/- 1.92 pg/ml versus 5.41 +/- 1.60 pg/ml; p < 0.05), plasma sTNF-R55 (1.16 +/- 0.47 ng/ml versus 0.67 +/- 0.13 ng/ml; p < 0.0001) and sTNF-R75 (3.65 +/- 1.29 ng/ml versus 2.25 +/- 0.43 ng/ml; p < 0.0001) levels were significantly higher in the COPD patients than in the healthy controls. Importantly, circulating leptin levels (log transformed) did correlate well with BMI and %fat, but not with TNF-alpha or with sTNF-R levels in the COPD patients. These data suggest that circulating leptin is independent of the TNF-alpha system and is regulated physiologically even in the presence of cachexia in patients with COPD.
Self-Assembly of Gold Nanoparticles on Gallium Droplets: Controlling Charge Transport through Microscopic Devices (2013)

We describe the spontaneous assembly of ligand-stabilized gold nanoparticles on the surfaces of gallium droplets in suspension. By subsequent deposition of these coated droplets onto substrates with patterned electrodes, we form devices that have controlled architecture on the nanometer scale, which allows control of electron transport. In particular, we show that microscopic droplets can be brought into contact with one another with a monolayer of nanoparticles between them, resulting in a junction where electron transport is limited by the Coulomb blockade effect. We characterize the gallium surfaces by optical and electron microscopy and measurement of the interfacial tension. We measure the current-voltage characteristics of devices consisting of one or more Ga droplets and nanoparticle layers in series. The results agree well with the conventional theory of the Coulomb blockade and show how this approach could be used to form hierarchically structured electronic devices.
19.5%-Efficient Back-Contact Silicon Heterojunction Solar Cell With Self Aligned Metallization Using Multilayer Aluminum Foils (2018)

We present advances in a back-contact, back-junction metallization strategy using preformed multilayers of aluminum foil with a polymer insulator. The low-cost multilayer foils can be conductively bonded to substrates using nonconducting adhesives. The properties of this bonding process are discussed. We also demonstrate different cell structures based on multilayer foils. One approach leverages features of the multilayer foil to produce a self-aligned base contact, leading to a process with only a single alignment step. A champion silicon heterojunction cell with this foil metallization achieved 19.5% efficiency. We further show first results on a completely alignment-free back contact process enabled by multilayer foil metallization.
Optically active quantum dots with induced circularly polarized luminescence in amphiphilic peptide dendron hydrogel (2018)

In this study, water-soluble semiconductor quantum dots (QDs) showing induced circularly polarized luminescence (CPL) in an organic-inorganic coassembled hydrogel were demonstrated. Achiral QDs could be encapsulated into a chiral peptide dendron hydrogel through cogelation. These cogels displayed intense induced circularly polarized emission. In addition, the direction of the CPL property of QD cogels could be regulated by the supramolecular chirality of hydrogels. Our findings reveal that the emergence of CPL achiral QDs can be triggered by the chirality transfer in a multiple-component dendron hydrogel system. This study has given a new understanding into the design of functional chiroptical materials.
