Markerless attenuation correction for carotid MRI surface receiver coils in combined PET/MR imaging (2015)

The purpose of the study was to evaluate the effect of attenuation of MR coils on quantitative carotid PET/MR exams. Additionally, an automated attenuation correction method for flexible carotid MR coils was developed and evaluated. The attenuation of the carotid coil was measured by imaging a uniform water phantom injected with 37 MBq of 18F-FDG in a combined PET/MR scanner for 24 min with and without the coil. In the same session, an ultra-short echo time (UTE) image of the coil on top of the phantom was acquired. Using a combination of rigid and non-rigid registration, a CT-based attenuation map was registered to the UTE image of the coil for attenuation and scatter correction. After phantom validation, the effect of the carotid coil attenuation and the attenuation correction method were evaluated in five subjects. Phantom studies indicated that the overall loss of PET counts due to the coil was 6.3% with local region-of-interest (ROI) errors reaching up to 18.8%. Our registration method to correct for attenuation from the coil decreased the global error and local error (ROI) to 0.8% and 3.8%, respectively. The proposed registration method accurately captured the location and shape of the coil with a maximum spatial error of 2.6 mm. Quantitative analysis in human studies correlated with the phantom findings, but was dependent on the size of the ROI used in the analysis. MR coils result in significant error in PET quantification and thus attenuation correction is needed. The proposed strategy provides an operator-free method for attenuation and scatter correction for a flexible MRI carotid surface coil for routine clinical use.
Cardiac biomarkers and arterial stiffening: data from the Gutenberg Health study (2013)

Purpose: Deleterious effects of arterial stiffness (AS) on central hemodynamics such as increased mechanical load on the left ventricle with subsequent cardiac hypertrophy or reduced coronary perfusion with subsequent myocardial ischemia, are well recognized. Nonetheless, data on the association between circulating biomarkers reflecting hemodynamic stress or myocardial ischemia/necrosis with AS are still scarce. We investigated the association between stiffness index (SI), derived from digital volume pulse (DVP) and cardiac biomarkers in a population-based setting. Methods: The present analysis is based on data from the first 5,000 participants of the Gutenberg Health Study, which represents a population-representative cohort from the Rhine-Main-region, stratified for age, gender and residence. AS was assessed by DVP analysis using a PCA2 device and SI was calculated. Several cardiac biomarkers were measured: high-sensitive Troponin I (TnI), carboxy-terminal proarginin-Vasopressin (CT-proAVP; copeptin), N-terminal pro B-type natriuretic peptide (NT-proBNP), midregional pro-atrial natriuretic peptide (MR-proANP) and midregional proadrenomedullin (MR-proADM). Due to technical and logistic constraints, AS was available in 4,468 subjects (2,350 men/2,118 women; aged 35-74 yrs). Results: An inverse correlation was found between SI and MR-proANP in both genders (r=-0.12 in men, r=-0.14 in women (partial correlations, adjusted for age)). No significant correlations were detected between SI and remaining markers (all r between -0.0083 and 0.044). In addition, in a fully adjusted regression model, controlled for age, classical cardiovascular (CV) risk factors as well as for significant interactions between age and diabetes and age and hypertension, only MR-proANP was significantly associated with AS in both genders: 1 SD increase in logMR-pro-ANP concentration was associated with a decrease in SI by 0.4 m/s in males and by 0.3 m/s in females (both p<0.0001). NT-proBNP was independently inversely related to SI in women in a fully adjusted model (β=-0.15, p= 0.0065), whereas in men the association was attenuated after adjustment for CV risk factors and became only borderline significant. No associations were found between SI and TnI, copeptin and MR-proADM; neither in crude nor in multivariable adjusted models. Conclusion: These data indicate an inverse association of natriuretic peptides with AS, which is probably related to their cardioprotective and potent vasodilative properties. Interestingly, the association seems to be more pronounced for MR-proANP than for NT-proBNP.
Session 20 Overview: High-Performance VCOs (2021)

The quest for voltage-controlled oscillators (VCOs) with lower phase noise and higher efficiency continues. In this session, the first paper describes a technique to obtain a wideband common-mode resonance and minimize the 1/f noise upconversion into phase noise in a broadband fashion. Next, a distributed multi-core oscillator, which achieves very low phase noise and an improved FoM with respect to the state-of-theart of multi-core oscillators, is presented. The final paper showcases a quad-core millimeter-wave oscillator with low phase noise.

Assessment of learning goals in university students from the perspective of ‘person-situation interaction’: the Situated Goals Questionnaire (SGQ-U) / Evaluación de las metas de aprendizaje en estudiantes universitarios desde la perspectiva de la ‘interacción persona-situación’: el Cuestionario de Metas Situadas (CMS-U) (2018)

Academic behaviour takes place in a context in which the nature of class activities and interactions can influence the student’s motivation to learn. So, in order to study this influence, it is necessary to assess not only the personal variables that can motivate academic behaviour, but also the degree to which students are sensitive to different situational or task characteristics. In this case, the interaction person-situation is analysed using a new tool, the ‘situated-goal questionnaire’ for university students. Data of 770 students were analysed using confirmatory techniques, as well as Anova and regression techniques. According to results, the questionnaire has good psychometric characteristics. Besides, they showed the effect of the kinds of situation on the degree to which students declare the pursuit of different goals, as suggested by the person/situation interaction model, as well as the validity of both goals and sensitivity to situations for predicting engagement and self-estimated mean grade.
Tertiary Gleason Pattern 5 in Gleason 7 Prostate Cancer Predicts Pathological Stage and Biochemical Recurrence (2008)

In patients with Gleason sum 7 prostate cancer tertiary Gleason grade 5 is significantly associated with higher pT stage and biochemical recurrence. Larger studies are needed to assess the predictive value of tertiary grade compared to other established parameters in predicting the long-term oncological outcome after radical prostatectomy.

Demo (2017)

This demo paper presents FLEX-MONROE, a platform that facilitates better understanding of the status of current Mobile Broadband (MBB) networks (e.g. 3G and 4G/LTE) and enables performance improvements by allowing experimentation with controllable LTE parameters. The platform enables the investigation of the impact of low-level tweaks in network parameters in the LTE infrastructure on the application performance. We argue that FLEX-MONROE is crucial to provide guidelines on how to improve the application performance both in the current and future MBB networks.
[Antiandrogen withdrawal syndrome in the hormonal treatment of metastatic prostatic cancer in hormonal escape]. (1996)

A fall in the PSA level after stopping antiandrogens has been described at the stage of hormonal escape of prostatic cancer treated by complete androgen inhibition. The authors report a new case. The patient was offtially treated by pulpectomy and nitulamide for N+ prostatic carcinoma (PSA: 165 ng/ml). At the stage of hormonal escape, discontinuation of nitulamide induced a reduction of the PSA. Replacement of nitulamide by cytoproterone acetate was followed by a renewed increase of PSA, which again decreased after stomming cyproterone acetate. Three years later, the PSDA level was 3.5 ng/mg. This syndrome is probably due to mutation of the androgen receptor. In hormonal escape, suspension of all antiandrogens apart from LHRH analogues is recommended and can be followed by a temporary fall of PSA. No other antiandrogen must be administered in the place of the previous drug.
Inhibition of insulin‐like growth factor binding protein 5 proteolysis in articular cartilage and joint fluid results in enhanced concentrations of insulin‐like growth factor 1 and is associated with improved osteoarthritis (2002)

The findings suggest that direct inhibition of the serine protease C1s results in increased concentrations of intact IGFBP-5 and that proteolysis of IGFBP-3 is also inhibited, probably by the inhibition of some other protease. This increase in concentrations of intact IGFBP-3 and IGFBP-5 leads to an increase in IGF-1 which is associated with an improvement in joint architecture during the development of OA.

Localization of Inv in a distinctive intraciliary compartment requires the C-terminal ninein-homolog-containing region (2008)

The primary cilium is an antenna-like structure extending from the surface of most vertebrate cells. Loss or mutation of ciliary proteins can lead to polycystic kidney disease and other developmental abnormalities. inv mutant mice develop multiple renal cysts and are a model for human nephronophthisis type 2. The mouse Inv gene encodes a 1062-amino-acid protein that is localized in primary cilia. In this study, we show that the Inv protein (also known as inversin) is localized at a distinctive proximal segment of the primary cilium, using GFP-tagged Inv constructs and anti-Inv antibody. We named this segment the Inv compartment of the cilium. Further investigation of the Inv protein showed that 60 amino acids at its C-terminal, which contains ninein homologous sequences, are crucial for its localization to the Inv compartment. Fluorescence recovery after photobleaching analysis revealed that the Inv protein was dynamic within this compartment. These results suggest that localization of the Inv protein to the Inv compartment is actively regulated. The present study revealed that the primary cilium has a distinct molecular compartment in the body of the primary cilium with a specific confining and trafficking machinery that has not been detected previously by morphological examination.
Retrieval of aerosol extinction coefficient profiles from Raman lidar data by inversion method (2012)

We regard the problem of differentiation occurring in the retrieval of aerosol extinction coefficient profiles from inelastic Raman lidar signals by searching for a stable solution of the resulting Volterra integral equation. An algorithm based on a projection method and iterative regularization together with the L-curve method has been performed on synthetic and measured lidar signals. A strategy to choose a suitable range for the integration within the framework of the retrieval of optical properties is proposed here for the first time to our knowledge. The Monte Carlo procedure has been adapted to treat the uncertainty in the retrieval of extinction coefficients.
Synthesis and Crystal Structure of a Cationic Trinuclear Ruthenium(II) Complex, [Ru3(μ2-Cl)3(μ3-Cl)2{1,2-bis(diphenylphosphino)benzene}3]PF6 (1997)

Treatment of [RuCl2(η6-C6H6)]2 with 1,2-bis(diphenylphosphino)benzene (abbreviation DPB) led to [RuCl(η6-C6H6)(dpb)]Cl (2). When complex 2 in methanol was heated at 50 °C for 13 h, a cationic trinuclear complex [Ru3(μ2-Cl)3(μ3-Cl)2(dpb)3]Cl (3a) was obtained in 75% yield with liberation of the benzene ligand. The cationic trinuclear structure was confirmed by X-ray analysis of [Ru3Cl5(dpb)3]PF6 (3b). Three ruthenium atoms were linked by three μ2-bridging chloride atoms and two face-capped μ3-chloride atoms to form a triangular core of Ru3(μ2-Cl)3(μ3-Cl)2.
Weighted prediction methods for improved motion compensation (2009)

Weighted prediction in the H.264/MPEG-4 AVC video coding standard is a coding tool used primarily for improving coding efficiency during illumination changes, such as fading transitions. In this paper, we extend the usage of weighted prediction within the context of motion compensation in H.264, to further improve coding efficiency even for scenes with constant illumination characteristics. This is done by better exploiting coding tools already available in H.264 such as reference list reordering and multiple reference prediction.
‘Neighbour smoke’: proposal for a new term (2010)

Transfer of secondhand smoke (SHS) between apartments in multi-unit dwellings is an emerging public health issue, an issue of health equity and it is a challenge for property managers and operators who try to deal with the problem. As public knowledge about SHS increases, renters are becoming increasingly concerned about SHS transfer between apartments. Moreover, the increase in smoke-free workplaces and public places has been associated with increased support for further regulations. Although SHS is a known health hazard studies on SHS transfer in multi-unit dwellings are few. Moreover, they are difficult to search for because a common term has not been established. A common term would help researchers to describe this issue and make it easier to collect information on the topic.

To date, different terms have been used such as environmental tobacco smoke (ETS) transfer,1 ETS incursion,2 drifting …
Serratia Protease (1970)

The substrate specificity of Serratia protease was determined using various synthetic substrates. The enzyme did not participate in the hydrolysis of di- and tri-peptides except benzoylglycylleucinamide which was split at a limited rate into hippuric acid and leucinamide. The enzyme action on larger peptides was also studied. The enzyme cleaved the gly-leu bond in eledoisin related peptide and the gly-phe bond in bradykinin. The enzyme split oxidized insulin B-chain at twelve different peptide bonds.
KM3NeT front-end and readout electronics system: hardware, firmware and software (2019)

The KM3NeT research infrastructure being built at the bottom of the Mediterranean Sea will host water-Cherenkov telescopes for the detection of cosmic neutrinos. The neutrino telescopes will consist of large volume three-dimensional grids of optical modules to detect the Cherenkov light from charged particles produced by neutrino-induced interactions. Each optical module houses 31 3-inch photomultiplier tubes, instrumentation for calibration of the photomultiplier signal and positioning of the optical module and all associated electronics boards. By design, the total electrical power consumption of an optical module has been capped at seven watts. This paper presents an overview of the front-end and readout electronics system inside the optical module, which has been designed for a 1~ns synchronization between the clocks of all optical modules in the grid during a life time of at least 20 years.
Statistical analysis of NOAA solar/weather tapes. Program summary. Final report (1977)

A major mission of the U.S. Coast Guard is the task of providing and maintaining Maritime Aids to Navigation. These aids are located on and near the coastline and inland waters of the United States and its possessions. A computer program, Design Synthesis and Performance Analysis (DSPA), has been developed by the Jet Propulsion Laboratory to demonstrate the feasibility of low-cost solar array/battery power systems for use on flashing lamp buoys. To provide detailed, realistic temperature, wind, and solar insolation data for analysis of the flashing lamp buoy power systems, the two DSPA support computer program sets: MERGE and STAT were developed. A general description of these two packages is presented in this program summary report. The MERGE program set will enable the Coast Guard to combine temperature and wind velocity data (NOAA TDF-14 tapes) with solar insolation data (NOAA DECK-280 tapes) onto a single sequential MERGE file containing up to 12 years of hourly observations. This MERGE file can then be used as direct input to the DSPA program. The STAT program set will enable a statistical analysis to be performed of the MERGE data and produce high or low or mean profiles of the data and/or do amore » worst case analysis. The STAT output file consists of a one-year set of hourly statistical weather data which can be used as input to the DSPA program.« less

Soft Decision Demodulation and Transform Coding of Images (1983)

This paper describes a transform image coding system that uses soft decision demodulation to control channel errors. In soft decision demodulation, if certain received bits of a codeword representing a coefficient are unreliable, then the codeword is rejected and the corresponding coefficient is replaced with an estimate. By monitoring the three highest energy DCT coefficients, the reconstructed image quality can be improved for a channel with a bit error probability of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> .
Effect of long term treatment with azithromycin on disease parameters in cystic fibrosis: a randomised trial (2002)

AZM in adults with CF significantly improved QOL, reduced CRP levels and the number of respiratory exacerbations, and reduced the rate of decline in lung function. Long term AZM may have a significant impact on morbidity and mortality in patients with CF. Further studies are required to define frequency of dosing and duration of benefit.
The novelCGRPreceptor antagonistBIBN4096BSalleviates a postoperative intestinal inflammation and prevents postoperative ileus (2015)

CGRP is immediately released during abdominal surgery and induces a neurogenic inflammation via activation of abdominal macrophages. BIBN4096BS prevented IM-induced inflammation and restored GI motility. These findings suggest that CGRP receptor antagonism could be instrumental in the prevention of POI.

Coiling after Treatment with the Woven EndoBridge Cerebral Aneurysm Embolization Device (2012)

Retreatment options after the use of the newly launched Woven EndoBridge cerebral aneurysm embolization device (WEB II) are mostly unknown. Nine months after WEB II implantation, a 55-year-old female patient presented with regrowth of an MCA aneurysm. For the first time, standard balloon-assisted coiling was used to close the regrown aneurysm proximal to the WEB II implant. We report on the feasibility and safety of balloon-assisted coiling after implantation of the WEB II device.
