“Time is bandwidth”? Narrowing the gap between subjective time perception and Quality of Experience (2012)

Over the last couple of years, the scope of Quality of Experience (QoE) research has been constantly extended, most recently to the field of Web QoE in the context of HTTP-based applications. In this paper, we address the question whether it is sufficient to reduce typical Web QoE assessment scenarios to the temporal aspects of waiting for task completion, which would allow to attribute the resulting logarithmic laws to well-known psychological insights on human time perception. We demonstrate that while this attribution is valid for simple waiting tasks which are typical for simple data services like e.g. file downloads, the case of interactive web browsing is much more complex. We show that this is not only because technical issues prevent bandwidth and download time from being directly correlated with each other in a simple manner, but also because user perceived web page load times strongly deviate from technical page load times. Consequently, existing approaches towards assessment and modeling of web browsing QoE have to be critically reviewed and redesigned.
New heat stable polyethers, polyketones and polysulfones (1999)

Benzofuro[2,3-b]benzofuran-2,9-dicarboxylic acid (I), 4,4′-[sulfonylbis(p-phenyleneoxy)]dibenzoic acid, and 2,7-biphenylene dicarboxylic acid were reacted with a number of diaryl ethers in phosphorous pentoxide/methane sulfonic acid (PPMA) media. Diacid I also was reacted with an equimolar mixture of two diaryl ethers. FT-IR spectroscopy and elemental analysis data confirmed the molecular structure of the polymers. They show good thermal stability.
Human urokinase receptor expression is inhibited by amiloride and induced by tumor necrosis factor and phorbol ester in colon cancer cells (1994)

The modulation of urokinase plasminogen activator receptor (uPAR) gene expression by tumor necrosis factor alpha (TNF alpha), phorbol ester (PMA) and amiloride was studied in three colon cancer cell lines. uPAR mRNA and protein were induced by TNF alpha and by PMA but were inhibited by amiloride at concentrations of 0.1 to 1 mM in the presence or absence of TNF alpha and PMA. Nuclear run-on transcription assay indicated that the effects of amiloride and TNF alpha were mediated at least in part at the transcriptional level, whereas PMA may act in part via a posttranscriptional mechanism. These results suggested that uPAR gene expression is modulated by multiple signal transduction pathways.
Radiotherapy induced xerostomia: Mechanisms, diagnostics, prevention and treatment – Evidence based up to 2013 (2013)

Definition and prevalence of xerostomia were shortly presented. Radiosensitivity of the salivary glands, mechanism, diagnostics, and possible prediction methods of the intensity of xerostomia in the pre-radiotherapy period are widely discussed. Prevention of xerostomia: salivary gland sparing radiotherapy, cytoprotective agents, preservation by stimulation with cholinergic muscarinic agonists, surgical transfer of submandibular glands according to ASCO Management Guidelines and Quality of Life Recommendations were cited. Oral Care Study Group (2010) therapeutic approaches for relieving xerostomia are referred. Current therapies, restricted to symptom relief such as oral hygiene with fluoride agents, antimicrobials to prevent dental caries, saliva substitutes to relieve symptoms, and sialogenic agents to stimulate saliva were also discussed.
Palladium-Catalyzed Oxidative Annulation of Acrylic Acid and Amide with Alkynes: A Practical Route to Synthesize α-Pyrones and Pyridones (2014)

A range of internal alkynes smoothly underwent palladium-catalyzed oxidative annulations with acrylic acid and amide to afford α-pyrones and pyridones in good to excellent yields with high regioselectivity. The usage of O2 (1 atm) as a stoichiometric oxidant with H2O as the only byproduct under mild conditions makes this process more attractive and practical.
Diagnosis of Urea Cycle Disorders (1987)

Hyperammonemia in pediatrics can be due to a number of causes (defects of urea cycle enzymes or transport of its metabolites, organic acidurias, acyl-CoA dehydrogenase or carnitine deficiency, liver bypass or nonspecific insufficiency) requiring differentiated rapid treatment for a satisfactory prognosis. The specific diagnosis cannot be established by clinical means. Thus the work-up rests on biochemical analyses. The methods used are detailed and their interpretation discussed. An algorithm for the interpretation of the data which can easily be computerized is presented. The procedure has proven practicable in 126 patients with urea cycle disorders.
The Undecimated Wavelet Decomposition and its Reconstruction (2007)

This paper describes the undecimated wavelet transform and its reconstruction. In the first part, we show the relation between two well known undecimated wavelet transforms, the standard undecimated wavelet transform and the isotropic undecimated wavelet transform. Then we present new filter banks specially designed for undecimated wavelet decompositions which have some useful properties such as being robust to ringing artifacts which appear generally in wavelet-based denoising methods. A range of examples illustrates the results
p40: A p63 Isoform Useful for Lung Cancer Diagnosis – A Review of the Physiological and Pathological Role of p63 (2012)

At present, p63, TTF-1, and Napsin-A are the main immunochemical markers used to distinguish squamous cell carcinoma (SCC) from lung adenocarcinoma (ADC). However, studies using antibodies against p63 have demonstrated false-positive results with positivity in some ADC. In contrast, the expression of one of the p63 isoforms (ΔNp63), detected by the antibody p40, is highly specific for SCC. Since most cases of lung cancer are diagnosed in small specimens (cytology/biopsies) and saving material for molecular analysis is mandatory, we recommended the use of p40 (in adjunct with TTF-1 and/or Napsin-A) as the best approach to discriminate SCC and lung ADC. In this paper, we review the physiological and pathological role of p63 isoforms as well as their use as diagnostic markers in lung SCC.
[Theoretical analysis of Cu-O bond stretching vibration out of CuO2 plane of bi-system high temperature]. (2000)

In this article, according to the molecule vibration theory and on the base of simple model, the stretching vibration modes of Cu-O bond out of CuO2 plane were analysed and stretching vibration frequencies were calculated. The calculating result approximately coincided with the result of experimental analysis.
A Low-Integrated-Phase-Noise 27–30-GHz Injection-Locked Frequency Multiplier With an Ultra-Low-Power Frequency-Tracking Loop for mm-Wave-Band 5G Transceivers (2017)

An ultra-low-phase-noise injection-locked frequency multiplier (ILFM) for millimeter wave (mm-wave) fifth-generation transceivers is presented. Using an ultra-low-power frequency-tracking loop (FTL), the proposed ILFM is able to correct the frequency drifts of the quadrature voltage-controlled oscillator of the ILFM in a real-time fashion. Since the FTL is monitoring the averages of phase deviations rather than detecting or sampling the instantaneous values, it requires only 600 μW to continue to calibrate the ILFM that generates an mm-wave signal with an output frequency from 27 to 30 GHz. The proposed ILFM was fabricated in a 65-nm CMOS process. The 10-MHz phase noise of the 29.25-GHz output signal was -129.7 dBc/Hz, and its variations across temperatures and supply voltages were less than 2 dB. The integrated phase noise from 1 kHz to 100 MHz and the rms jitter were -39.1 dBc and 86 fs, respectively.
Measurement of mutual inductance from the frequency dependence of impedance of AC coupled circuits using a digital dual-phase lock-in amplifier (2008)

We present a simple method for determining the mutual inductance between two coils in a coupled AC circuit using a digital dual-phase lock-in amplifier. The frequency dependence of the real and imaginary parts is measured as the coupling is changed. The mutual inductance decreases as the distance d between the centers of coils is increased. We show that the coupling is proportional to d−n with n≈3. This coupling is similar to that of two magnetic dipoles.
ZONAL APPROACH TO MODELING THERMALLY STRATIFIED ATRIA (2012)

Thermally stratified atria and similar spaces present challenges for building thermal-comfort and energy modeling. This work tests a zonal modeling method for dynamic thermal and energy simulation of a heavily glazed and thermally stratified atrium cooled by displacement ventilation. The goal of the study was to explore the extent to which this method offers any improvement over simpler methods with respect to assessing thermal comfort and energy consumption. This paper describes a thermal and bulk-airflow zonal modeling strategy that appears to capture the some of the principal effects of thermal plumes generated when glazed facades and other interior surfaces are heated by solar radiation. This approach may be applicable to a relatively broad range of projects with similar characte- ristics. A CFD tool running the same model of the space, but without the zonal subdivisions, was used to tune the dynamic thermal/bulk-airflow model and to assess the degree to which the latter provides consis- tently appropriate results with variation in solar gain. The zonal approach appears to have some advantage with respect to predicting thermal comfort as a function of heat removed from the interior of glazed facades; however, a comparison with a simpler method that does not use bulk-airflow modeling suggests that this simpler method may provide much of the same benefit with respect to assessing energy consumption.
New technique for detection of changes in QRS morphology of ECG signals (1983)

With the use of the electrocardiogram (ECG) as a prototype signal, a new technique was devised for detecting signals embedded in noise. Averaged "normal" digitized ECG signals formed a template to which subsequent ECG QRS complexes were compared. The difference between the averaged template signals and subsequent normal beats was white noise, whereas the difference between the template and ectopic beats consisted of nonrandom signal variation. The template to new signal comparison for the zero-, first-, second-, and third-order differences utilized an approximate F test. Accurate detection of abnormal signals associated with high- and low-frequency noise is accomplished with this method, and the practical clinical utility of the method is under study.

Molecular Bases of Cell-Cell Junctions Stability and Dynamics (2009)

Epithelial cell-cell junctions are formed by apical adherens junctions (AJs), which are composed of cadherin adhesion molecules interacting in a dynamic way with the cortical actin cytoskeleton. Regulation of cell-cell junction stability and dynamics is crucial to maintain tissue integrity and allow tissue remodeling throughout development. Actin filament turnover and organization are tightly controlled together with myosin-II activity to produce mechanical forces that drive the assembly, maintenance, and remodeling of AJs. In this review, we will discuss these three distinct stages in the lifespan of cell-cell junctions, using several developmental contexts, which illustrate how mechanical forces are generated and transmitted at junctions, and how they impact on the integrity and the remodeling of cell-cell junctions.
A Novel Approach to Smart Power System Integration (1989)

A three dimensional technology has been oriented towards the realisation of an integrated Smart Power application. The technology comprises integrated power and logic modules which are implemented as a Quasi-3D structure using SOI-CMOS and bulk-LDMOS gate-arrays for maximum design flexibility. The system, a stepper motor controller IC, uses a Silicon-on-Insulator technology to provide high quality isolation between the logic and power devices. The implementation of both power and logic devices in the SOI layer has been investigated using a 3D compatible process.
Analysis of <i>hTERT</i> expression in exfoliated cells from patients with bladder transitional cell carcinomas using SYBR green real-time fluorescence quantitative PCR (2007)

Our results show that SYBR green real-time fluorescence quantitative evaluation of hTERT mRNA could be a useful marker of tumor progression for the early diagnosis and prognosis of bladder cancers.
Collision Detection and Part Interaction Modeling to Facilitate Immersive Virtual Assembly Methods (2004)

Realistic part interaction is an important component of an effective virtual assembly application. Both collision detection and part interaction modeling are needed to simulate part-to-part and hand-to-part interactions. This paper examines several polygonal-based collision detection packages and compares their usage for virtual assembly applications with the Voxmap PointShell (VPS) software developed by the Boeing Company. VPS is a software developer’s toolkit for real-time collision and proximity detection, swept-volume generation, dynamic animation, and 6 degree-of-freedom haptics which is based on volumetric collision detection and physically based modeling. VPS works by detecting interactions between two parts: a dynamic object moving in the virtual environment, and a static object defined as a collection of all other objects in the environment. The method was found to provide realistic collision detection and physically-based modeling interaction, with good performance at the expense of contact accuracy. Results from several performance tests on VPS are presented. This paper concludes by presenting how VPS has been implemented to handle multiple dynamic part collisions and two-handed assembly using the 5DT dataglove in a projection screen virtual environment.
Pregnant women benefit from massage therapy (1999)

Twenty-six pregnant women were assigned to a massage therapy or a relaxation therapy group for 5 weeks. The therapies consisted of 20-min sessions twice a week. Both groups reported feeling less anxious after the first session and less leg pain after the first and last session. Only the massage therapy group, however, reported reduced anxiety, improved mood, better sleep and less back pain by the last day of the study. In addition, urinary stress hormone levels (norepinephrine) decreased for the massage therapy group and the women had fewer complications during labor and their infants had fewer postnatal complications (e.g., less prematurity).
An Electrochemical Study on the Dissolution of Copper and Silver from Silver‐Copper Alloys (1995)

The dissolution behavior of silver and copper from their elemental states and Ag/Cu alloys in ammoniacal solutions has been studied using rotating disk electrodes. The variables studied included concentration of ammonia, oxygen partial pressure, and rotating speed of the disk. The results have been interpreted in terms of the mixed potential theory. The effect of local current resistance on the overall current has also been examined as a part of the governing theory of the dissolution. The dissolution rate of copper from the alloys in terms of the same area of the Cu‐phase has been found to be higher than that from pure copper due to the galvanic coupling, and it increased with the increase of the silver content in the alloy. When the surface area fraction is about 0.5, the galvanic current between the Ag‐ and Cu‐phases is maximum. The dissolution of copper from its pure state and alloys is mainly oxygen diffusion controlled. Like pure silver, the dissolution of silver from its alloy is considered to be chemical reaction controlled.
Comparative Expression of NFκB Proteins in Melanocytes of Normal Skin vs. Benign Intradermal Naevus and Human Metastatic Melanoma Biopsies (2004)

Nuclear factor kappa B (NFkappaB) is an essential regulator of gene transcription for hundreds of genes, including many critically involved in apoptosis. NFkappaB complexes containing cRel generally activate pro-apoptotic genes, while those with RelA activate anti-apoptotic genes. We have previously shown that NFkappaB binding by RelA is constitutively elevated in human metastatic melanoma cultures relative to normal melanocytes. Here we extended our investigation to immunohistochemical analysis of human tissue biopsies. We found that RelA expression is significantly elevated in melanocytes of human naevi and melanomas relative to normal skin, but expression of its inhibitor IkappaB-alpha is significantly lower in metastatic melanomas than in intradermal naevi. Antibodies specific for the nuclear localization signal of RelA also showed significantly increased staining in metastatic melanoma biopsies. Notably, in melanomas and in naevi, we also found that RelA is phosphorylated at serine 529, and this activated form accumulates in the nuclei of melanomas. This suggests that increased expression and phosphorylation of RelA occurs at the stage of the benign naevus, but IkappaB-alpha is able to sequester RelA in the cytoplasm and regulate RelA transcriptional transactivation. We also found that antibodies against cRel show a progressive increase in staining from naevi to melanoma. However, staining for IkappaB-epsilon, which primarily inhibits the nuclear localization of cRel was also progressively increased, and cRel expression was predominantly cytoplasmic in melanomas. These results confirm that the altered expression of RelA found in metastatic melanoma cells in tissue culture is relevant to human tumors and offer new insights into the deregulation of NFkappaB signaling.
Clinically Relevant Differences in Accuracy of Enteral Nutrition Feeding Pump Systems (2006)

Background: There are clinically relevant discrepancies between prescribed volumes and delivered volumes of enteral nutrition (EN) in intensive care unit (ICU) patients. Next to EN‐protocol violations due to insufficient care, we hypothesized technical factors to be responsible for this deficit. The aim of this study was to determine the accuracy of EN feeding pump systems frequently used in the ICU. Methods: Thirteen commercially available EN feeding pumps with their own delivery systems were tested in 12 sessions with different EN feeding tubes and EN formulas in a laboratory setting. The reproducibility of the measurements was determined for the 8 best performing EN feeding pump systems. Results: There were clinically important differences between prescribed volumes and delivered volumes of EN in the tested EN feeding pump systems. The deficit in volume ranged from +66 mL (surplus of 66 mL) to –271 mL (deficit of 271 mL) per 24 hours (14% of prescribed volume). Viscosity of test fluids (water/EN feeding formulas) and resistance of test tubes had no influence on the delivered volume by the tested EN feeding pump systems, because differences between prescribed volumes and delivered volumes were consistently found for each system while varying these test settings. Conclusions: Differences between prescribed and delivered EN volumes are caused by the function and construction of EN feeding pump systems. To improve nutrition therapy, the flow rate has to be adjusted or the best‐performing EN feeding pump has to be purchased.
Attenuated‐dose idarubicin in acute myeloid leukaemia of the elderly: pharmacokinetic study and clinical results (1995)

AML in the elderly is characterized by intrinsic biological features implying an enhanced chemoresistance. Intensive chemotherapy should be the treatment of choice, but the standard doses could induce unacceptable rates of aplastic deaths. We evaluated the efficacy of an induction protocol with attenuated-dose idarubicin (IDA) 8 mg/m2 for 3 d plus cytarabine and etoposide in 26 AML patients aged > 60. 18 patients (69%) achieved CR, five (19%) were non-responders and three (12%) died during induction. To compare the pharmacokinetics of IDA between elderly and young patients, we assayed daily the serum level of the drug and of its metabolite (idarubicinol, IDAol) in a group of eight elderly patients who received a dose of 8 mg/m2 (group A) and in a group of nine younger AML patients treated with 12 mg/m2 (group B). The apparent terminal half-life of IDAol was significantly longer in the elderly than in the younger patients (mean half-life 59.7 h versus 41.4 h, P < 0.05). The values of the area under the serum concentration curve of IDAol indicated that the two patient groups received a very similar exposure to the drug despite the different doses. In conclusion, this protocol, based on attenuated doses of IDA, compares well with the results obtained previously in similar age-matched patient series.
The Appearance Variation Cue for Obstacle Avoidance (2011)

The appearance variation cue captures the variation in texture in a single image. Its use for obstacle avoidance is based on the assumption that there is less such variation when the camera is close to an obstacle. For videos of approaching frontal obstacles, it is demonstrated that combining the cue with optic flow leads to better performance than using either cue alone. In addition, the cue is successfully used to control the 16-g flapping-wing micro air vehicle DelFly II.
Physical characterization and electrical conductivity of Li1.2Ti1.8Al0.2(PO4)3 and Li1.2Ta0.9Al1.1(PO4)3 NASICON material (2018)

Sodium superionic conducting materials (NASICON) are promising solid electrolytes for Li-ion batteries and suitable to be used in the area that requires high energy density as well as rechargeable power sources. Fabrication of all-solid-state Li battery with non-flammable ceramics electrolyte has been strongly required to solve safety issues of present Li batteries. In this study, lithium titanium aluminium phosphate Li1+xTi2-xAlx(PO4)3, LTAP (x = 0.2) and lithium tantalum aluminium phosphate Li1+2xTa1-xAlx+1(PO4)3, LTaAP (x = 0.1) were prepared via conventional solid state reaction techniques at various sintering temperature ranging from 700 to 1000 Â°C. LTAP and LTaAP compositions attain their optimum sintering temperature at 800 Â°C. Physical properties of LTAP and LTaAP show the bulk density of 2.83 and 3.63 g/cm3 which resulted into high densification of the material. The XRD analysis revealed NASICON crystalline phase dominated by LiTi2(PO4)3 and minor impurity phases for LTaAP composition. Bulk conductivity values for LTAP and LTaAP were found to be 1.06 x 10-4 and 9.854 x 10-6 S/cm at room temperature. LTAP had better conductivity behavior compare to LTaAP composition which could be due to differences in their ionic radius (titanium, 0.605 nm tantalum, 0.64 nm and the aluminium, 0.53 nm) in sizes, though the conductivity obtained for both compositions has the capacity to serve as solid electrolyte material could be used in lithium ion rechargeable battery.
