Imaging sensor and imaging algorithms for quality inspection of flexible materials (2016)

The measurement of dark measurement objects with difficult surface characteristics is always a challenging task. Especially the measurement of pipes which cannot be measured in transmitted light conditions will lead to complicated situations during the image processing and the ongoing feature detection. In this paper two different methods will be presented which will overcome this problem. A quality control after the feature extraction the outer and inner diameter as well as the thickness of the insulation pipes is also presented. At the end both methods were evaluated using measurement process capability values. To find the best conditions for the imaging and measurement task a measurement set up using a multispectral camera as well as using an adjustable illumination was developed and promoted in this article.
False‐positive hepatitis C virus serology after placement of a ventricular assistance device (2015)

FP HCV Ab results following VAD placement are very common. Reversal of FP serology in several patients after VAD removal is suggestive of a possible association with the VAD hardware. Clinicians should be aware of this phenomenon, as it could lead to delays in determining eligibility for OHT and increased costs.
HIGH-THROUGHPUT KINETIC STUDY OF PEROXIDE CURING OF EPDM RUBBER (2011)

Abstract Mixing of EPDM and a peroxide curative via a solution route and subsequent curing were performed in a downscaled set-up. The resulting vulcanizates were characterized by a down-scaled hardness measurement and by Raman spectroscopy in a high-throughput experimentation compatible approach. The characterization results obtained on these vulcanizates agreed well with those obtained on corresponding vulcanizates prepared via conventional mill mixing. By indentation on vulcanizates cured for various curing times, a rheometer curve could be constructed. The conversion of the EPDM unsaturation and, thus, the extent of the addition reactions was quantified by Raman spectroscopy. Using both the indentation and the Raman data, the cross-link density resulting from combination reactions was estimated.
Comparison of InSAR two-pass and time series methods for analysing landslides in central Georgia, Caucasus (2012)

Different landslides have been detected in InSAR using different data analysis strategies: moving landslides (some cm per month) are detectable in two-pass InSAR results, where the same regions loose coherence in most other InSAR pairs. As a result, when analyzing InSAR time series, such landslides may remain undetected. On the other hand, slow landslide (some mm per year) or North-South (parallel to radar satellite orbit) moving landslides could only be identified in InSAR time series. Therefore, our future strategy is to detect landslides from InSAR by applying both approaches, two-pass InSAR and InSAR time series.
A phase I/II clinical trial of E6 T-cell receptor gene therapy for human papillomavirus (HPV)-associated epithelial cancers. (2017)

3009 Background: Engineered T-cell therapy has shown promise in B-cell malignancies and melanoma, but clinical investigation in epithelial cancers has been limited. Methods: We conducted a phase I/II clinical trial of T cells genetically engineered to express a T-cell receptor that targets an HLA-A*02:01-restricted epitope of E6 (E6 TCR T Cells) for patients with metastatic HPV-16+ carcinoma. The cell dose was escalated in cohorts of single patients (1 x 10 9 , 1 x 10 10 , and 1-2 x 10 11 cells). Patients received a nonmyeloablative conditioning regimen of cyclophosphamide and fludarabine, a single infusion of E6 TCR T Cells, and systemic high-dose aldesleukin. Results: Twelve patients were treated, 9 at the highest cell dose, plus one retreatment. The cancer types were 6 cervical, 4 anal, 1 oropharyngeal, and 1 vaginal. No dose-limiting toxicity, autoimmune adverse events, or cytokine storm were observed. Two patients with anal cancer treated at the highest cell dose experienced partial tumor responses lasting 6 and 3 months after treatment. The patient with a 6-month response had complete regression of one tumor and partial regression of two tumors that were resected upon progression; she has no evidence of disease 22 months after treatment. T-cell receptor gene transfer efficiency was 45 and 51% in the responding patients, and 47-76% (median 61%) in the non-responding patients. Responding patients showed robust levels of E6 TCR T cell memory (30 and 46% of circulating T cells 1-month after treatment). Non-responding patients showed wide-ranging levels of E6 TCR T cell memory (range 4-53%, median 29%). Expression of programmed cell death protein 1 (PD-1) by circulating E6 TCR T Cells 1-month after treatment was low in all patients ( &lt; 5%). The patient with a 6-month response had 7% E6 TCR T Cells in a resected tumor 10 months after treatment, 25% of which expressed PD-1. A patient with no response had no detectable E6 TCR T Cells in a resected tumor 3 months after treatment. Conclusions: E6 TCR T-cell therapy was safe at doses up to 2 x 10 11 cells. Regression of metastatic HPV+ carcinoma occurred in two patients following treatment, suggesting that TCR T-cell therapy can mediate epithelial cancer regression. Clinical trial information: NCT02280811.
Enhanced luminescence from catalyst-free grown InP nanowires (2007)

The surface effects in the optical properties of catalyst-free grown InP nanowires are investigated. Both as-grown nanowires and nanowires treated with hydrofluoric acid are studied using low- and room-temperature continuous-wave and time-resolved photoluminescence measurements and transmission electron microscopy. It is shown that the room-temperature photoluminescence intensity is increased by two orders of magnitude after the surface treatment, and that there is also a significant increase in the double-exponential photoluminescence decay time.
Computer Aided Design of Contiguous-Band Output Multiplexers(Comux) (1994)

A general multiplexer design procedure without dummy channels is described. Utilization of extensive computer modeling and optimization resulted. in excellent performance of the multiplexer. The selected configuration employs an H-plane T-junction manifold. A 12 GHz-12-channel contiguous multiplexer for satellite applications is presented. This software can be used to define a practical tuning methodology of such multiplexers.
A Multipronged Approach to the Study of Peruvian Ethnomedicinal Plants: A Legacy of the ICBG-Peru Project (2009)

A multidisciplinary and international team of scientists was assembled in the early 1990s to conduct an ethnobotanical study of plants used by the Aguaruna people of the Peruvian Amazon forest. The initial ethnobotanical project, carried out under the auspices of an International Cooperative Biodiversity Grant (ICBG), led to the collection of approximately 4000 plant species. Some members of the original team of scientists have continued this collaboration by focusing on potential sources of new anticancer, anti-infective, and wound-healing agents. This effort has uncovered several secondary metabolites representing a wide variety of chemical diversity. In this short review we describe some bioactive compounds of interest as part of our continuing collaboration.
Direct Brow Lift Combined with Suspension of the Orbicularis Oculi Muscle (2013)

The direct brow lift operation combined with plication/suspension of the superior and lateral portion of the orbicularis oculi muscle provides a simple, safe, and predictable means of correcting lateral brow ptosis. The scars were acceptable to all of the patients. For proper management of the frontalis tone, upper blepharoplasty and/or repair of eyelid levator function must be considered in addition to brow lift procedures.
Percutaneous access of the superior vena cava in patients with bilateral jugular-subclavian vein occlusion using wire-target access for placement of tunneled hemodialysis catheters: An important new tool for gaining upper body vascular access (2020)

This study presents the technique of percutaneous wire-target access of the superior vena cava (SVC) in patients with bilateral jugular-subclavian vein occlusion requiring a tunneled hemodialysis catheter. A 3-year retrospective review of five patients was performed. The femoral vein is accessed percutaneously and a 5F sheath inserted. This is followed by placement of a pigtail catheter (wire-target) in the SVC with cavography. The SVC is percutaneously cannulated at the level of the pigtail under fluoroscopy, and a guidewire is passed into the vena cava with confirmation by injection of contrast material. A tunneled hemodialysis catheter is then placed. The wire-target technique of SVC access can be used safely and effectively to establish upper body catheter access when traditional techniques are not possible.
Leading Critically: A Grounded Theory of Applied Critical Thinking in Leadership Studies (2011)

This study describes the development of a grounded theory of applied critical thinking in leadership studies and examines how student-centered experiential learning in leadership education bridged critical thinking with action. Over three semester undergraduate students in an upper level leadership studies course at a large four-year public institution in the southeastern United States completed a written assignment in which they were asked to define the concept of “leading critically.” A grounded theory of critical leadership – utilizing critical thinking skills to make decisions about leadership actions in different situations – emerged after completing a qualitative document analysis of these papers and incorporating the researchers’ existing knowledge of leadership and student development theory. The hope is that this research will create dialogue concerning new approaches to leadership education and encourage practices that apply critical thinking skills to leadership.
High-precision atmospheric oxygen measurement comparisons between a newly built CRDS analyzer and existing measurement techniques (2019)

Abstract. Carbon dioxide and oxygen are tightly coupled in land–biospheres CO2–O2 exchange processes, while they are not coupled in oceanic exchange. For this reason, atmospheric oxygen measurements can be used to constrain the global carbon cycle, especially oceanic uptake. However, accurately quantifying the small (~ 1–100 ppm) variations in O2 is analytically challenging due to the very large atmospheric background which constitutes about 20.9 % (~ 209 500 ppm) of atmospheric air. Here we present comprehensive laboratory and field studies for a newly developed high-precision oxygen mixing ratio and isotopic composition analyzer (Picarro G-2207) that is based on cavity ring-down spectroscopy (CRDS). From the laboratory tests, we have calculated a short-term precision (standard error of one-minute measurements) of
High Performance X-Ray Transmission Windows Based on Graphenic Carbon (2015)

A novel x-ray transmission window based on graphenic carbon has been developed with superior performance compared to beryllium transmission windows that are currently used in the field. Graphenic carbon in combination with an integrated silicon frame allows for a window design which does not use a mechanical support grid or additional light blocking layers. Compared to beryllium, the novel x-ray transmission window exhibits an improved transmission in the low energy region ($0.1 hbox{keV}-3 hbox{keV}$ ) while demonstrating excellent mechanical stability, as well as light and vacuum tightness. Therefore, the newly established graphenic carbon window, can replace beryllium in x-ray transmission windows with a nontoxic and abundant material. Index terms: Beryllium, Carbon, Graphene, Thin films, X-ray applications, X-ray detectors
Experimental demonstration of nonlinearity and dispersion compensation in an embedded link by optical phase conjugation (2006)

We report in this letter, the experimental demonstration of simultaneous dispersion and nonlinearity compensation in an embedded link characterized by strongly asymmetrical power profiles. This result is obtained by using a highly efficient optical phase conjugator based on a periodically poled lithium-niobate waveguide, combined with two small dispersion-compensating elements properly inserted in the link.
Imaging medium changes during a hydraulic stimulation using the distortion matrix framework: case of an Enhanced Geothermal System (EGS) in Espoo, Finland. (2023)

In 2018, the company St1 Oy performed an Enhanced Geothermal System (EGS) experiment using near-real-time seismic monitoring as feedback for the pumping procedure and thus allowing the control of the induced seismicity. Between 4 June and 22 July (49 days), ~18,000 cubic meters of water was injected at around 6 km depth beneath the University campus in Otaniemi, Espoo, Finland (Kwiatek el al. 2019). The hydraulic stimulation and post-stimulation stages were monitored by a temporary ~100 three-components geophone network installed by the Institute of Seismology, University of Finland (Hillers et al. 2020). If the requirements for induced seismicity have been successfully met, the medium changes produced by the hydraulic stimulation remain unclear. Especially with regard to the activation or opening of cracks. Recent application of the distortion matrix concept (Badon et al. 2020) in seismology (Touma et al. 2021) allows us to consider resolving some of these questions by imaging the distribution of the scatterers in the medium during the different injection stages. The distortion matrix operator makes it possible to correct a large part of the aberrations present in images obtained by focusing in depth a reflection matrix recorded at the surface. The phase distortions of the seismic wavefield due to complex velocity distributions can be recovered for any virtual source in the medium by comparing the recorded reflection matrix to the ideal geometric wave-front corresponding to this virtual source. By taking advantage of this powerful approach this study present 3D images of the volume surrounding the injection well of the EGS experiment.
<title>High-accuracy all-fiber optical current sensor</title> (1996)

The effect of ribbing and pressurization on the vibro-acoustic response of a turbulent boundary layer excited panel (2011)

One of the largest contributors to interior aircraft noise is the direct radiation from the wall panels excited by turbulent boundary layer (TBL) flows. The wall panels are designed with ribbing to increase their stiffness and strength while maintaining a relatively low weight. The effect of the ribbing on the vibro-acoustic response is examined for TBL flow excitation. Normal modes of a typical aluminum aircraft panel are computed and compared with and without the ribs. Wavenumber transforms of the mode shapes reveal increased sensitivity of the ribbed panel to high wavenumber excitation. TBL forcing functions are then converted into modal space and used to compute the radiated sound power of each panel. The increase in radiated sound power will be discussed in terms of wavenumber sensitivity. A preload due to pressurization is then applied to the ribbed panel and the modes, wavenumber spectrum and radiated sound power are recomputed. The pressurization causes a significant change in the modal content and subsequently the wavenumber spectrum and radiated power. The general effect of preload will be discussed in the context of interior aircraft noise predictions.
Diversity in Sensing with Sensor Arrays: Hardware/Software for Artificial Senses (2009)

With all of the great progress in chemical sensing and the prodigious literature on sensor arrays and the artificial chemical senses (nose and tongue), there is yet very much to learn about sensors and sensor arrays and their design and application. The signal in the artificial nose array starts with a simple chemical interaction of the sensor layer and the analyte producing an analytically relevant signal. The signal contains information about the nature and concentration of the analyte by virtue of the temporal, spatial, and parallel sensing process in an array. Extraction of the analytical information about the analyte may be accomplished by compensation, calibration, or computational modeling [algorithms] that extract the relevant part of the sensor signal.

The Use of Heavy Metal Complexes in Organic LEDs and Solar Cells (2007)

There has been a great deal of interest in developing new materials for the fabrication of light emitting diodes (OLEDs). We have prepared a range of intensely luminescent Ir(III) and Pt(III) complexes, which have found application in both monochromatic and white OLEDs. The role of the Ir and Pt in these complexes is to achieve efficient emission from the triplet excitons formed in the electroluminescence process. In my talk I will briefly discuss device architectural and materials choices that are made to improve efficiencies to their limits. Using this approach we have achieved internal efficiencies of nearly 100%. In addition to our work on monochromatic OLEDs, we have spent a great deal of time working with broadband, white emissive OLEDs. I will discuss the chemistry of these design of these devices as well.
Electropolymerized Poly(3,4-ethylenedioxythiophene) (PEDOT) Coatings for Implantable Deep-Brain-Stimulating Microelectrodes (2019)

Conducting polymers have been widely explored as coating materials for metal electrodes to improve neural signal recording and stimulation because of their mixed electronic-ionic conduction and biocompatibility. In particular, the conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) is one of the best candidates for biomedical applications due to its high conductivity and good electrochemical stability. Coating metal electrodes with PEDOT has shown to enhance the electrode's performance by decreasing the impedance and increasing the charge storage capacity. However, PEDOT-coated metal electrodes often have issues with delamination and stability, resulting in decreased device performance and lifetime. In this work, we were able to electropolymerize PEDOT coatings on sharp platinum-iridium recording and stimulating neural electrodes and demonstrated its mechanical and electrochemical stability. Electropolymerization of PEDOT:tetrafluoroborate was carried out in three different solvents: propylene carbonate, acetonitrile, and water. The stability of the coatings was assessed via ultrasonication, phosphate buffer solution soaking test, autoclave sterilization, and electrical pulsing. Coatings prepared with propylene carbonate or acetonitrile possessed excellent electrochemical stability and survived autoclave sterilization, prolonged soaking, and electrical stimulation without major changes in electrochemical properties. Stimulating microelectrodes were implanted in rats and stimulated daily, for 7 and 15 days. The electrochemical properties monitored in vivo demonstrated that the stimulation procedure for both coated and uncoated electrodes decreased the impedance.
Successful management of suspected propofol dependence with phenobarbital in an adult patient with COVID-19 (2023)

Information concerning propofol withdrawal syndrome in the literature is limited. Our experience demonstrates the successful use of phenobarbital to facilitate propofol weaning after prolonged exposure.
Solvent effects on differentiation of mouse brain tissue using laser microdissection ‘cut and drop’ sampling with direct mass spectral analysis (2018)

Combined TOF-MS and SWATH-MS data differentiated white, grey, granular, and nucleus mouse tissue regions with greater accuracy than when solely using TOF-MS data. Using 90/10 (v/v) methanol/chloroform, tissue regions were perfectly differentiated. These results will guide future studies looking to utilize the potential of LMD-LVC/ESI-MS for tissue and disease differentiation.
Experimental determination of bending rigidity and saddle splay modulus in bicontinuous microemulsions (2013)

Elastic properties of surfactant membranes can be described in terms of the bending rigidity κ and the saddle splay modulus . Phase diagram measurements and neutron scattering experiments allowed the determination of these parameters. Recent simulations showed that the bending rigidity, which is deduced from the characteristic length scales in the microemulsion, is a mixture of and κ. By combining neutron spin echo (NSE) spectroscopy, small angle neutron scattering (SANS) and phase diagram measurements, we show that also experimentally the different contributions can be separated. For supercritical CO2 microemulsions and bicontinuous microemulsions with additives, the prefactors of the and κ contributions are determined and compared to those from simulations.

Molecular Diversity of a Putative Virulence Factor: Purification and Characterization of Isoforms of an Extracellular Serine Glutamyl Endopeptidase of Enterococcus faecalis with Different Enzymatic Activities (2004)

A previously identified gene sprE of Enterococcus faecalis strain OG1 was shown to encode an extracellular serine protease that appears to belong to the glutamyl endopeptidase I staphylococcal group. A single form of SprE with a molecular mass of 25 kDa and a pH optimum between 7.0 and 7.5 was isolated from culture supernatant of wild-type E. faecalis strain OG1RF (TX4002); this form was apparently generated by cleavage of the Ser-1-Leu1 and Arg230-Leu231 peptide bonds of the secreted zymogen. In contrast, the culture supernatant of the gelatinase-null mutant, TX5264, with a nonpolar deletion of gelE which encodes the E. faecalis gelatinase, was found to contain several forms of SprE proteolytically processed on both the N and C termini; in addition to a full-length zymogen and a truncated zymogen, three mature forms of the SprE proteinase, Leu1-Ala237, Ser-1-Glu227, and Leu1-Glu227, were identified. As with the V8 proteinase of Staphylococcus aureus, the closest homologue of SprE, all of the active forms cleaved specifically Glu-Xaa peptide bonds but with substantially different efficiencies, while none was able to hydrolyze peptide bonds with Asp in the P1 position. The most active of all these enzyme forms against several substrates, including human fibrinogen and beta-chain insulin, was the Ser-1-Glu227 (-1S-SprE) isolated from TX5264; -1S-SprE, in contrast to other forms of SprE, was unstable at 37 degrees C, apparently due to autodegradation. In conclusion, our results demonstrate that sprE encodes a highly specific serine-type glutamyl endopeptidase, the maturation of which is dependent on the presence of gelatinase. In the absence of gelatinase activity, the aberrant processing of pro-SprE results in the appearance of a "superactive" form of the enzyme, -1S-SprE.
