Možnosti a využití laserové řádkovací konfokální mikroskopie (2008)

V příspěvku jsou popsány různé aplikace laserového řádkovacího konfokálního mikroskopu Olympus LEXT OLS 3000. Výhody konfokálního mikroskopu byly využity pro charakterizaci mikrostruktury velmi jemných multifázových ocelích s vysokou pevností. Z těchto ocelí byly vyrobeny miniaturní zkušební vzorky pro zkoušku rázem v ohybu, jejichž tvar a rozměry byly kontrolovány pomocí trojrozměrného modelu povrchu získaného na LEXTu. Díky trojrozměrnému obrazu skutečného reliéfu povrchu bylo možné sledovat také lomovou plochu těchto vzorků po destrukci. Software konfokálního mikroskopu umožňuje rovněž stanovení drsnosti povrchu. Tato možnost byla využita na příkladu srovnávacího měření drsnosti plechů s různou úpravou povrchu.
Advance Abrasion Resistant Materials for Mining (2004)

The high-density infrared (HDI) transient-liquid coating (TLC) process was successfully developed and demonstrated excellent, enhanced (5 times higher than the current material and process) wear performance for the selected functionally graded material (FGM) coatings under laboratory simulated, in-service conditions. The mating steel component exhibited a wear rate improvement of approximately one and a half (1.5) times. After 8000 cycles of. wear testing, the full-scale component testing demonstrated that the coating integrity was still excellent. Little or no spalling was observed to occur.
IVOA Recommendation: Simple Spectral Access Protocol Version 1.1 (2012)

The Simple Spectral Access (SSA) Protocol (SSAP) defines a uniform interface to remotely discover and access one dimensional spectra. SSA is a member of an integrated family of data access interfaces altogether comprising the Data Access Layer (DAL) of the IVOA. SSA is based on a more general data model capable of describing most tabular spectrophotometric data, including time series and spectral energy distributions (SEDs) as well as 1-D spectra; however the scope of the SSA interface as specified in this document is limited to simple 1-D spectra, including simple aggregations of 1-D spectra. The form of the SSA interface is simple: clients first query the global resource registry to find services of interest and then issue a data discovery query to selected services to determine what relevant data is available from each service; the candidate datasets available are described uniformly in a VOTable format document which is returned in response to the query. Finally, the client may retrieve selected datasets for analysis. Spectrum datasets returned by an SSA spectrum service may be either precomputed, archival datasets, or they may be virtual data which is computed on the fly to respond to a client request. Spectrum datasets may conform to a standard data model defined by SSA, or may be native spectra with custom project-defined content. Spectra may be returned in any of a number of standard data formats. Spectral data is generally stored externally to the VO in a format specific to each spectral data collection; currently there is no standard way to represent astronomical spectra, and virtually every project does it differently. Hence spectra may be actively mediated to the standard SSA-defined data model at access time by the service, so that client analysis programs do not have to be familiar with the idiosyncratic details of each data collection to be accessed.

Spectrographic Determination of Aluminium in Ferrosilicon (1961)

In the process control and technical improvement of the ferrosilicon metal industry, speeding up of the determination of Al in ferrosilicon products has been a foremost requirement. For these purposes, the wet chemical analysis is tedious and lacks the rapidity required. In order to solve these problems, a quantitative spectrographic determination of Al in ferrosilicon metal was studied with some statistical techniques. The following factors were investigated in this study; excitation sources, shape of electrode, internal standard-buffer, parameters of intermittent a.c. arc, factors in the sample preparation and analytical operation, and sample quantity in sampling. The outline of the method obtained from the results of the experiments was as follows; a sample of ferrosilicon powder (500 mg) is mixed with the previously prepared internal standard-buffer (750 mg) (C:BaCl2·2H2O=2:1), loaded into the lower cup electrode and arced for 20 sec in an intermittent a. c. arc (interm. ratio 1/20, interm. No. 1 time/sec., resistance 20 Ω and exposure time 20 sec). The analytical line pair was Al I 3082 Å-Ba I 3072 Å. By this method, ferrosilicon samples could be analysed in 3 hours with the precision of about 6% in terms of coefficient of variation. The concentration range of Al investigated in this study was 0.1∼2.0%, but a little modification might extend this range.
OpenSR: An Open-Source Stimulus-Response Testing Framework (2015)

Stimulus–response (S–R) tests provide a unique way to acquire information about human perception by capturing automatic responses to stimuli and attentional processes. This paper presents OpenSR, a user-centered S–R testing framework providing a graphical user interface that can be used by researchers to customize, administer, and manage one type of S–R test, the implicit association test. OpenSR provides an extensible open-source Web-based framework that is platform independent and can be implemented on most computers using any operating system. In addition, it provides capabilities for automatically generating and assigning participant identifications, assigning participants to different condition groups, tracking responses, and facilitating collecting and exporting of data. The Web technologies and languages used in creating the OpenSR framework are discussed, namely, HTML5, CSS3, JavaScript, jQuery, Twitter Bootstrap, Python, and Django. OpenSR is available for free download.
Effect of <i>ABCG2</i> genotype and mRNA expression on the bioavailability of topotecan (2004)

2015 Background: The ATP-binding cassette transporter ABCG2 (breast cancer resistance protein; BCRP) functions as an efflux transporter for many drugs and is expressed at high levels in the human small intestine. It has been demonstrated that some individuals possess a nonsynonymous single-nucleotide polymorphism at nucleotide 421, substituting lysine for glutamine on position 141 at exon 5, and express low amounts of ABCG2. Methods: In this prospective exploratory study, duodenal biopsies were obtained before oral administration of topotecan on day 1 (dose, 2.3 mg/m2) and i.v. infusion on day 2 (dose, 1.5 mg/m2) in 18 adult Caucasian cancer patients (10 female/8 male; median age, 54 years). Pharmacokinetic data were obtained on days 1 and 2. Topotecan concentrations in plasma were determined by liquid chromatography with fluorescence detection, and analyzed by noncompartmental methods. Enterocyte (villin)-corrected mRNA expression levels of ABCG2 and ABCB1 (P-glycoprotein) were measured by real-time TaqMan analysis, and all patients were genotyped by cycle sequencing for ABCG2 421C>A. Results: Complete topotecan pharmacokinetic data were available for 13 patients. The mean (± SD) area under the curves after oral and i.v. administration were 109 ± 35.7 ng×h/mL and 218 ± 62.3 ng×h/mL, respectively. Substantial intra- and interindividual variation in mRNA expression of ABCG2 and ABCB1 was observed in the intestinal samples (N = 12). Two patients were heterozygous variant for ABCG2421C>A (14%; allele frequency, 7.14%), and 12 patients carried the wild-type sequence; 4 samples showed no amplification. The heterozygous CA allele was associated with a 1.3-fold increased oral bioavailability of topotecan [31.4% (wild-type, N = 10) versus 42.0% (heterozygous, N = 2); P = 0.037]. The lowest combined mRNA expression of ABCG2 and ABCB1 was observed in one of the patients that was heterozygous variant for ABCG2 421C>A. Conclusions: This pilot study indicates that ABCG2 genotype is correlated with altered topotecan pharmacokin-etics. The current observation warrants confirmation and further investigation in a larger patient population involving different ethnic groups. No significant financial relationships to disclose.
Development of One-Step Polishing Machine for On-Site Optical Connector Assembling (2010)

A new optical-connector-end polishing machine for On-Site was developed. This machine can polish a connector end with only one-step by a very simple mechanism. Using this machine, the end polishing of the optical connector can become very easy and fast. we characterized the one-step polishing process. As a result, it revealed that the machine has sufficient power for good polished planes unless only one-step. Polished planes had good precision met with the specification and the polishing had good reproducibility
The energy and entropy of VLSI computations (2002)

We introduce the concept of energy index, a measure which can be used to estimate the pourer dissipation of a standard implementation of the high-level specification for an asynchronous circuit. This energy index is related to information-theoretic entropy measures. It is shown how these measures can be used to design low-power circuits.
Anytime scheduling with neural networks (2002)

Scheduling techniques have been intensively studied by several research communities and have been applied to a wide range of applications in computer and manufacturing environments. In computer systems, scheduling is an important approach to address real-time constraints associated with a set of computing tasks to be executed on one or several computers. Most of the scheduling problems are NP-hard, which is why heuristic and approximation algorithms must be used for large problems. Obviously these methods are of interest when they provide near optimal solutions with a polynomial computational complexity. This paper presents results for scheduling a set of nonpreemptive tasks by using a Hopfield neural network model. We present in this paper how this approach can solve scheduling problems following the "anytime" paradigm.
Shape‐Controlled Growth of Micrometer‐Sized Gold Crystals by a Slow Reduction Method (2006)

Shaping up nicely…︁ Micrometer-sized gold crystals have been synthesized through a binary mixture of amine ligand molecules in the presence of a gold precursor under slow growth conditions (see picture). A wide range of morphologies in the form of triangles, octahedra, pentagonal decahedra, platelets, and nanowires with well-defined morphologies can be derived by varying the composition and ratio of the ligand mixture.
Removal of Adherent Noises in Images by Using Multiple Cameras (2007)

In this paper, we propose a new method that can remove view-disturbing noises from images taken with multiple cameras. In outdoor environment, it is often the case that scenes taken by cameras are hard to see because of adherent noises on the surface of the lens protecting glass. The proposed method analyses multiple camera images describing the same scene, and synthesizes an image in which adherent noises are eliminated. We show the effectiveness of the proposed method through experimental results.
A Low-Power 26-GHz Transformer-Based Regulated Cascode SiGe BiCMOS Transimpedance Amplifier (2013)

Low-power high-speed optical receivers are required to meet the explosive growth in data communication systems. This paper presents a 26 GHz transimpedance amplifier (TIA) that employs a transformer-based regulated cascode (RGC) input stage which provides passive negative-feedback gain that enhances the effective transconductance of the TIA's input common-base transistor; reducing the input resistance and isolating the parasitic photodiode capacitance. This allows for considerable bandwidth extension without significant noise degradation or power consumption. Further bandwidth extension is achieved through series inductive peaking to isolate the photodetector capacitance from the TIA input. The optimum choice of series inductive peaking value and key transformer parameters for bandwidth extension and jitter minimization is analyzed. Fabricated in a 0.25-µm SiGe BiCMOS technology and tested with an on-chip 150 fF capacitor to emulate a photodiode, the TIA achieves a 53 dBΩ single-ended transimpedance gain with a 26 GHz bandwidth and 21.3 pA/ <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\sqrt{\rm Hz}$</tex></formula> average input-referred noise current spectral density. Total chip power including output buffering is 28.2 mW from a 2.5 V supply, with the core TIA consuming 8.2 mW, and the chip area including pads is 960 µm x 780 µm.
Modelling sequential text with an adaptive topic model (2012)

Topic models are increasingly being used for text analysis tasks, often times replacing earlier semantic techniques such as latent semantic analysis. In this paper, we develop a novel adaptive topic model with the ability to adapt topics from both the previous segment and the parent document. For this proposed model, a Gibbs sampler is developed for doing posterior inference. Experimental results show that with topic adaptation, our model significantly improves over existing approaches in terms of perplexity, and is able to uncover clear sequential structure on, for example, Herman Melville’s book “Moby Dick”. 1

Decision regret in men living with and beyond nonmetastatic prostate cancer in the United Kingdom: A population‐based patient‐reported outcome study (2020)

This large-scale study demonstrates the benefit of patient involvement in treatment decision-making for nonmetastatic PCa. However, men experiencing side effects and poorer HRQL report greater DR. Promoting engagement in clinical decision-making represents good practice and may reduce the risk of subsequent regret.
Retinoids and carnosol suppress cyclooxygenase-2 transcription by CREB-binding protein/p300-dependent and -independent mechanisms. (2002)

Treatment with retinoic acid (RA) or carnosol, two structurally unrelated compounds with anticancer properties, inhibited phorbol ester (PMA)-mediated induction of activator protein-1 (AP-1) activity and cyclooxygenase-2 (COX-2) expression in human mammary epithelial cells. The induction of COX-2 transcription by PMA was mediated by increased binding of AP-1 to the cyclic AMP response element (CRE) of the COX-2 promoter. Inhibition of the histone acetyltransferase activity of CREB- binding protein (CBP)/p300 blocked the induction of COX-2 by PMA. Treatment with carnosol but not RA blocked increased binding of AP-1 to the COX-2 promoter. Because AP-1 binding was unaffected by RA, we investigated whether RA inhibited COX-2 transcription via effects on the coactivator CBP/p300. Treatment with RA stimulated an interaction between RA receptor-alpha and CBP/p300; a corresponding decrease in the interaction between CBP/p300 and c-Jun was observed. Importantly, overexpressing CBP/p300 or dominant-negative RA receptor-alpha relieved the suppressive effect of RA on PMA-mediated stimulation of the COX-2 promoter. To elucidate the mechanism by which carnosol inhibited COX-2 transcription, its effects on protein kinase C (PKC) signaling were determined. Carnosol but not RA inhibited the activation of PKC, ERK1/2, p38, and c-Jun NH2-terminal kinase mitogen-activated protein kinase. Overexpressing c-Jun but not CBP/p300 reversed the suppressive effect of carnosol on PMA-mediated stimulation of COX-2 promoter activity. Thus, RA acted by a receptor-dependent mechanism to limit the amount of CBP/p300 that was available for AP-1-mediated induction of COX-2. By contrast, carnosol inhibited the induction of COX-2 by blocking PKC signaling and thereby the binding of AP-1 to the CRE of the COX-2 promoter. Taken together, these results show that small molecules can block the activation of COX-2 transcription by distinct mechanisms.
1‐(Aziridine) carbonyl chlorides and 1‐(aziridine) carbonyl quaternary ammonium chlorides. Rearrangement to 2‐(chloroalkyl) isocyanates (1967)

Abstract Aziridine reacted with phosgene in the presence of an acid acceptor or with 1,1′‐carbonylbis(pyridinium) chloride to produce 1‐(aziridine)carbonyl chloride (XII) or 1‐(aziridine)carbonyl pyridinium chloride (XIII), respectively, as transient intermediates. Attempts to trap and observe (XII) and (XIII) at ‐10° were unsuccessful. These elusive materials underwent facile rearrangements to 2 ‐ chloroethyl isocyanate under these conditions. Aziridine reacted with 1,1′‐carbonylbis(triethylammonium)chloride (VII) at ‐20° to give 1‐(aziridine) carbonyl triethylammonium chloride (X) as a transient intermediate which proceeded to 2‐chloroethyl isocyanate. At ‐10° this reaction produced N,N ‐diethyl‐1‐aziridinecarboxamide. Aziridine reacted with a large excess of phosgene in the absence of an acid acceptor to give N ‐2‐(chloroethyl) carbamoyl chloride (III), 1,1′‐bis(2‐chloroethyl) urea (IV) and 2‐(β‐chloroethylamino)‐2‐oxazoline hydrochloride (V). Possible mechanisms for these reactions are discussed.

Remitting seronegative symmetrical synovitis with pitting edema following intravesical bacillus Calmette-Guérin instillation. (2001)

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare syndrome of undetermined etiology occurring in the elderly. We describe the first case of RS3PE in a HLA-B27 positive 65-year-old man following intravesical bacillus Calmette-Guérin (BCG) instillation for bladder carcinoma. He developed symmetrical arthritis and synovitis involving wrists, knees, ankles, and metatarsophalangeal joints, with marked pitting edema of the dorsa of both hands and feet, fever, and elevated acute phase reactants. Right knee effusion revealed nonspecific sterile inflammatory fluid. He responded dramatically to nonsteroidal antiinflammatory drugs. BCG instillation may have triggered active symmetrical synovitis via local T cell activation and a T-helper-1 (Th-1)/Th-2 inflammatory profile.
Overview of the Workshop on Recommendation in Complex Scenarios 2019 (ComplexRec 2019) (2019)

Over the past decade, recommendation algorithms for ratings prediction and item ranking have steadily matured. However, these state-of-the-art algorithms are typically applied in relatively straightforward and static scenarios: given information about a user's past item preferences in isolation, can we predict whether they will like a new item or rank all unseen items based on predicted interest? In reality, recommendation is often a more complex problem: the evaluation of a list of recommended items never takes place in a vacuum, and it is often a single step in the user's more complex background task or need. The goal of the ComplexRec 2019 workshop is to offer an interactive venue for discussing approaches to recommendation in complex scenarios that have no simple one-size-fits-all solution.
Fast Spheres, Shadows, Textures, Transparencies, and Image Enhancements in Pixel-Planes. (1985)

<p>Pixel-planes is a logic-enhanced memory system for raster graphics and imaging. Although each pixel-memory is enhanced with a one-bit ALU, the system's real power comes from a tree of one-bit address that can evaluate linear expressions Ax + By + C for every pixel (x,y) simultaneously, as fast as the ALUs and the memory circuits can accept the results. The development of a variety of algorithms that exploit this fast linear expression evaluation capability has started. The paper reports some of those results. Illustrated in this paper is a sample image from a small working prototype of the Pixel- planes hardware and a variety of images from simulations of a full-scale system. Timing estimates indicate that 30,000 smooth shaded triangles can be generated per second, or 21, 000 smooth-shaded and shadowed triangles can be generated per second, or over 25,000 shaded spheres can be generated per second. Image-enhancement by adaptive histogram equalization can be performed within 4 seconds on a 512 x 512 image.</p>
