Studies on the ribosomal RNA operons of Listeria monocytogenes (1992)

A 23S rRNA gene of Listeria monocytogenes was cloned into pUC19 on a 6.2-kb Pst I fragment. Hybridisation studies demonstrated the presence of the 5S and partial 16S rRNA genes within the clone. The nucleotide sequence of the region encoding the 23S rRNA was found to be highly homologous with those of other low G + C Gram-positive bacteria. The 16S-23S intergenic spacer region was amplified using PCR technology and revealed two product sizes, the larger of which contained tRNA(Ala) and tRNA(Ileu) genes. Further tRNA genes were found downstream of the 5S rRNA gene.
Performance analysis of motion-compensated de-interlacing systems (2006)

A lot of research has been conducted on motion-compensated (MC) de-interlacing, but there are very few publications that discuss the performances of de-interlacing quantatively. The various methods are compared through their performance on known video sequences. Linear system analysis of interlaced video and de-interlacer are proposed in. It is well established that the performance of the MC methods outperform the fixed or motion-adaptive methods when the motion vectors used are reliable and true to the scene content. Being an open-loop process the performance of the MC de-interlacers degrade drastically when there are motion vector errors. In this paper, a linear system analysis of MC video upconversion systems is presented and the effects of motion vector accuracy on system performance are analyzed. We investigate the various factors that contribute to the motion vector inaccuracy, such as incorrect motion modelling, acceleration between the frames, and insufficient interpolation kernel.

Polarized photoluminescence and order parameters of <i>“in situ”</i> photopolymerized liquid crystal films (2000)

Oriented liquid crystal polymer films with different degrees of cross-linking have been obtained by “in situ” photopolymerization of different mesogenic samples at various temperatures. These samples are mixtures of a naphthalene based monoacrylate and a crosslinking agent (diacrylate). Photoluminescence has been obtained by adding a cyanoterphenyl chromophore. The order parameters of the polymer films have been derived from dichroic measurements. An increase of the dichroism has been found when the diacrylate content and/or the polymerization temperature decrease. The dichroism is also bigger if the chromophore is in a “guest-host” configuration than if it is covalently attached to the polymer backbone. The dichroic ratios do not change under annealing up to 200 °C but some photodegradation of the luminescence is observed in the naphthalene containing films.
Realization and Control of the Lupo EL Electric Vehicle (2012)

During fall 2009, the Eindhoven University of Technology started the development of the Lupo EL (Electric Lightweight) research vehicle. The vehicle is fully operational now, allowed to drive on the public road and used in several research projects. This paper will focus more in-depth on the vehicle development and the research performed. The following subjects will be addressed: vehicle realization, specification and performance, data acquisition systems and control systems.
Proteolytic Dissection of Zab, the Z-DNA-binding Domain of Human ADAR1 (1999)

Zalpha is a peptide motif that binds to Z-DNA with high affinity. This motif binds to alternating dC-dG sequences stabilized in the Z-conformation by means of bromination or supercoiling, but not to B-DNA. Zalpha is part of the N-terminal region of double-stranded RNA adenosine deaminase (ADAR1), a candidate enzyme for nuclear pre-mRNA editing in mammals. Zalpha is conserved in ADAR1 from many species; in each case, there is a second similar motif, Zbeta, separated from Zalpha by a more divergent linker. To investigate the structure-function relationship of Zalpha, its domain structure was studied by limited proteolysis. Proteolytic profiles indicated that Zalpha is part of a domain, Zab, of 229 amino acids (residues 133-361 in human ADAR1). This domain contains both Zalpha and Zbeta as well as a tandem repeat of a 49-amino acid linker module. Prolonged proteolysis revealed a minimal core domain of 77 amino acids (positions 133-209), containing only Zalpha, which is sufficient to bind left-handed Z-DNA; however, the substrate binding is strikingly different from that of Zab. The second motif, Zbeta, retains its structural integrity only in the context of Zab and does not bind Z-DNA as a separate entity. These results suggest that Zalpha and Zbeta act as a single bipartite domain. In the presence of substrate DNA, Zab becomes more resistant to proteases, suggesting that it adopts a more rigid structure when bound to its substrate, possibly with conformational changes in parts of the protein.
Sample Size Necessary for Estimation of Markov Transition Matrix (2014)

Estimation of transition probability matrix in a Markov chain gives trouble when some of the observations are null. So in order to avoid this the availability of non-null observations from states are worked out ensuring the minimum number of samples. Also the probabilities of availability of such samples has been worked out so that sufficient probability of getting
non-null observations for all transitions may be checked for practical purposes. Average sample number in simple case is worked out for demonstration.
Crystal structure of the C form of stearic acid (1971)

The crystal structure of the C form of stearic acid has been determined from X-ray powder diffraction patterns, The crystals are monoclinic, space group P21/a, with unit-cell dimensions: a= 9·36, b= 4·95, c= 50·7 Å. β= 128 °15′ and Z= 4. The crystal structure has been determined by trial-and-error methods to R 0·086. The structural parameters are compared with those of similar compounds, in particular the same acid in the polymorphous B form.
Absorbable gelatin plug does not prevent iatrogenic preterm premature rupture of membranes after fetoscopic laser surgery for twin–twin transfusion syndrome (2013)

CAP did not reduce the overall risk for iPPROM and did not increase the procedure-to-delivery interval. Further research is needed to identify other methods to prevent iPPROM and prolong pregnancy after laser therapy.
The IBM PCIXCC: A new cryptographic coprocessor for the IBM eServer (2004)

IBM has designed special cryptographic processors for its servers for more than 25 years. These began as very simple devices, but over time the requirements have become increasingly complex, and there has been a never-ending demand for increased speed. This paper describes the PCIXCC, the new coprocessor introduced in the IBM z990 server. In many ways, PCIXCC is a watershed design. For the first time, a single product satisfies all requirements across all IBM server platforms. It offers the performance demanded by today's Web servers, it supports the complex and specialized cryptographic functions needed in the banking and finance industry, and it uses packaging technology that leads the world in resistance to physical or electrical attacks against its secure processes and the secret data it holds. Furthermore, it is programmable and highly flexible, so that its function can be easily modified to meet new requirements as they appear. These features are possible because of innovative design in both the hardware and embedded software for the card. This paper provides an overview of that design.
Coloration in a WO3 film (1976)

The electrical coloration in WO3 films in practical fabrication originates at the interface between WO3 and CaF2 and migrates towards the cathode. The rate of migration is higher than 1.4×10−9 cm2/V sec.
Method for isolation of adult mouse cardiac myocytes for studies of contraction and microfluorimetry (1996)

We describe techniques for the isolation of Ca(2+)-tolerant myocytes from mouse (2 to 6 mo old) ventricle for measurements of mechanics of contraction and microfluorimetry. Our approach involved special modifications of existing methods that had been developed for other species but were not successful when applied to the mouse heart. Important features of the method are 1) a requirement for careful timing (< 5 min) of perfusion with nominally Ca(2+)-free solution; 2) perfusion with a solution containing a specially selected batch of collagenase in the presence of a low Ca2+ concentration; and 3) meticulous attention to water quality. Using this method, we could consistently isolate durable, Ca(2+)-tolerant myocytes from adult mouse hearts with a yield of approximately 50%. With slight modifications, the method should enable other investigators to isolate mouse cardiomyocytes for their specific experimental applications.
A view of Kanerva's sparse distributed memory (1986)

Pentti Kanerva is working on a new class of computers, which are called pattern computers. Pattern computers may close the gap between capabilities of biological organisms to recognize and act on patterns (visual, auditory, tactile, or olfactory) and capabilities of modern computers. Combinations of numeric, symbolic, and pattern computers may one day be capable of sustaining robots. The overview of the requirements for a pattern computer, a summary of Kanerva's Sparse Distributed Memory (SDM), and examples of tasks this computer can be expected to perform well are given.
Molecular Diversity of 5S-rRNA Spacer Domain in Fritillaria Species Revealed by PCR Analysis (1999)

Beimu (bulbs of Fritillaria) is an important traditional Chinese herbal medicine commonly used as an antitussive and expectorant. There are about 25 species and varieties of Fritillaria that carry the name Beimu on commercial markets. The price for each Beimu may differ by more than 100-fold. However, the identification of the origin of a particular species on the market is difficult. Here, a molecular method was used to identify various species of Fritillaria regardless of their geographical origin. The 5S-rRNA coding sequence is highly conserved in higher eukaryotes, but the spacer sequence of the 5S-rRNA gene is variable among different species. Total genomic DNA from fresh leaves and bulbs of Fritillaria cirrhosa, F. puqiensis, F. anhuiensis, and F. thunbergii was extracted. The 5S-rRNA spacer region of the extracted DNAs was amplified by PCR with a pair of primers located within the conserved coding region. The isolated cDNA clones (approximately 600 bp) covering the 5S-rRNA spacer domain were sequenced. By aligning the isolated nucleotide sequences of the four Fritillaria species, sequence diversity was found in the spacer region. Furthermore, a unique EcoR I site was used for the rapid identification of different species of Fritillaria. To our knowledge, this is the first report on the detection of 5S-rRNA spacer domain sequences of Fritillaria and their use to identify species.

This pilot study indicates that automatic detection of semitranslucent and pink blush areas in BCC is feasible using colors and first-order texture statistics.
Many-Core Token-Based Adaptive Power Gating (2013)

Among power dissipation components, leakage power has become more dominant with each successive technology node. Leakage energy waste can be reduced by power gating. In this paper, we extend token-based adaptive power gating (TAP), a technique to power gate an actively executing core during memory accesses, to many-core Chip Multi-Processors (CMPs). TAP works by tracking every system memory request and its estimated time of arrival so that a core may power gate itself without performance or energy loss. Previous work on TAP <citerefgrp xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><citeref refid="ref11"/></citerefgrp> shows several benefits compared to earlier state-of-the-art techniques <citerefgrp xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><citeref refid="ref10"/></citerefgrp> , including zero performance hit and 2.58 times average energy savings for out-of-order cores. We show that TAP can adapt to increasing memory contention by increasing power-gated time by 3.69 times compared to a low memory-pressure case. We also scale TAP to many-core architectures with a distributed wake-up controller that is capable of supporting staggered wake-ups and able to power gate each core for 99.07% of the time, achieved by a non-scalable centralized scheme.
Variable NK Cell Receptors Exemplified by Human KIR3DL1/S1 (2011)

Variegated expression of variable NK cell receptors for polymorphic MHC class I broadens the range of an individual's NK cell response and the capacity for populations and species to survive disease epidemics and population bottlenecks. On evolutionary time scales, this component of immunity is exceptionally dynamic, unstable, and short-lived, being dependent on coevolution of ligands and receptors subject to varying, competing selection pressures. Consequently these systems of variable NK cell receptors are largely species specific and have recruited different classes of glycoprotein, even within the primate order of mammals. Such disparity helps to explain substantial differences in NK cell biology between humans and animal models, for which the population genetics is largely ignored. KIR3DL1/S1, which recognizes the Bw4 epitope of HLA-A and -B and is the most extensively studied of the variable NK cell receptors, exemplifies how variation in all possible parameters of function is recruited to diversify the human NK cell response.
Silanole, XV. Alkoxy‐silanole – partielle Kieselsäureester (1979)

Abstract Es werden Methoden beschrieben, die die Darstellung von Trialkoxysilanolen und Dialkoxy‐silandiolen ermöglichen. Voraussetzung hierfür sind sterisch wirksame RO‐Gruppen, die sowohl die OH‐Kondensation als auch die RO‐Solvolyse verhindern. Durch potentiometrische Titration in Pyridin bzw. Pyridin/Isopropanol wird die relative Acidität von Trialkoxy‐silanolen bestimmt.
In vivo imaging of unstained tissues using a compact and flexible multiphoton microendoscope (2012)

We use a compact and flexible multiphoton microendoscope (MPME) to acquire in vivo images of unstained liver, kidney, and colon from an anesthetized rat. The device delivers femtosecond pulsed 800 nm light from the core of a raster-scanned dual-clad fiber (DCF), which is focused by a miniaturized gradient-index lens assembly into tissue. Intrinsic fluorescence and second-harmonic generation signal from the tissue is epi-collected through the core and inner clad of the same DCF. The MPME has a rigid distal tip of 3 mm in outer diameter and 4 cm in length. The image field-of-view measures 115 μm by 115 μm and was acquired at 4.1 frames/s with 75 mW illumination power at the sample. Organs were imaged after anesthetizing Sprague-Dawley rats with isofluorane gas, accessing tissues via a ventral-midline abdominal incision, and isolating the organs with tongue depressors. In vivo multiphoton images acquired from liver, kidney, and colon using this device show features similar to that of conventional histology slides, without motion artifact, in ~75% of imaged frames. To the best of our knowledge, this is the first demonstration of multiphoton imaging of unstained tissue from a live subject using a compact and flexible MPME device.
Current distribution, resistance, and inductance for superconducting strip transmission lines (1991)

A method for the calculation of the current distribution, resistance, and inductance matrices for a system of coupled superconducting transmission lines having finite rectangular cross-section is presented. These calculations allow accurate characterization of both high-T/sub c/ and low-T/sub c/ superconducting strip transmission lines. For a single stripline geometry with finite ground planes, the current distribution, resistance, inductance, and kinetic inductance are calculated as functions of the penetration depth for various film thicknesses. These calculations are then used to determine the penetration depth for Nb, NbN, and YBa/sub 2/Cu/sub 3/O/sub 7-x/ superconducting thin films from the measured temperature dependence of the resonant frequency of a stripline resonator. The calculations are also used to convert measured temperature dependence of the quality factor to the intrinsic surface resistance as a function of temperature for an Nb stripline resonator.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Distemper Outbreak and Its Effect on African Wild Dog Conservation (2002)

In December 2000, an infectious disease spread through a captive breeding group of African wild dogs (Lycaon pictus) in Tanzania, killing 49 of 52 animals within 2 months. The causative agent was identified as Canine distemper virus (CDV) by means of histologic examination, virus isolation, reverse transcriptase-polymerase chain reaction analysis, and nucleotide sequencing. This report emphasizes the importance of adequate protection against infectious diseases for the successful outcome of captive breeding programs of endangered species.
Regulation of iron metabolism in the acute‐phase response: interferon γ and tumour necrosis factor α induce hypoferraemia, ferritin production and a decrease in circulating transferrin receptors in cancer patients (1998)

Our data point to a central role for the cytokine network in the modulation of iron metabolism in the acute-phase response and anaemia of chronic disease. TNF, possibly via induction of IL-6, and IFN-gamma induce hypoferraemia, which may in part result from a decrease in tissue iron release based on a primary stimulation of ferritin synthesis. The fall in sTfR levels may reflect an impaired erythroid growth and/or TfR expression mediated by TNF and IFN-gamma.
Synthesis, characterization and polymerization of dendrimers with methacrylic end groups (1996)

Abstract Dendritic methacrylic crosslinking agents were synthesized by modification of amino functional poly(propyleneimine) dendrimers. On the basis of model reactions, several experimental methods for the introduction of methacrylate end groups were evaluated. In case of the Michael reaction of 2‐(acryloyloxy)ethyl methacrylate (1) the amino‐end groups of the dendrimers of the second, the fourth or the fifth generation add exclusively onto the acrylic double bonds of 1 forming methacrylic end groups in the modified dendrimers. The quantitative and uniform conversion could be proved by NMR spectroscopy. Analogous dendrimer modifications were carried out with mixtures of 1 and other acrylates. The dendrimeric methacrylates of different generations were polymerized in solution and bulk at 80°C with 2.2′‐azoisobutyronitrile as initiator. The polymerization enthalpy of the dendrimeric methacrylates was determined by differential scanning calorimetry and shows that the polymerization of approximately every double bond takes place. The polymerization of methacrylic dendrimers yields crosslinked polymers with glass transition temperatures near or below room temperature.
CARO'S ACID - AN IMPROVEMENT OVER HYDROGEN PEROXIDE FOR BRIGHTENING OF CHEMICAL PULP (1998)

Caro’s acid can be used in alkaline pH in an extraction stage (E) of a DEopDED bleaching sequence to improve pulp brightness. This is analogous to peroxide in the E-stage. A brightness increase as much as 13% ISO was obtained when a DEopD pulp having a brightness of 64.5% ISO was treated with 0.15% Caro’s acid (as active oxygen AO) in the subsequent E-stage. Under similar conditions 0.2% peroxide (as H2O2) gave a moderate brightness increase of about 9 points. However, most of the brightness gained in the extraction stage was lost when a final D-stage was carried out, resulting in only 2% overall increase in brightness in the final pulp. On the other hand, when 0.2 - 0.3% Caro’s acid (as AO) was applied to a DEopD bleached 81.5% ISO pulp, a brightness of about 89 - 89.5% was achieved. Similarly, when 0.05-0.1% Caro’s acid (as AO) was applied as a final treatment, as in high density application, to a DEopD bleached 86.7% ISO pulp, a brightness gain of about 2-2.7% ISO was achieved. About the same magnitude of brightness gain was obtained from an equivalent amount of peroxide application as well. However, the major advantages of using Caro’s acid in the high density chest are maximum brightness in short time with very little or no residual chemical in the pulp and the final pH remaining in the near neutral range. The benefits of Caro’s acid outweighs peroxide and makes Caro’s acid a suitable bleach chemical for final stage bleaching and for High Density bleaching where control for a fixed retention time is not feasible.
Efficacy of CAR T-cell Therapy in Large Tumors Relies upon Stromal Targeting by IFNγ (2014)

Adoptive T-cell therapy using chimeric antigen receptor-modified T cells (CAR-T therapy) has shown dramatic efficacy in patients with circulating lymphoma. However, eradication of solid tumors with CAR-T therapy has not been reported yet to be efficacious. In solid tumors, stroma destruction, due to MHC-restricted cross-presentation of tumor antigens to T cells, may be essential. However, CAR-Ts recognize antigens in an MHC-independent manner on cancer cells but not stroma cells. In this report, we show how CAR-Ts can be engineered to eradicate large established tumors with provision of a suitable CD28 costimulatory signal. In an HER2-dependent tumor model, tumor rejection by HER2-specific CAR-Ts was associated with sustained influx and proliferation of the adoptively transferred T cells. Interestingly, tumor rejection did not involve natural killer cells but was associated instead with a marked increase in the level of M1 macrophages and a requirement for IFNγ receptor expression on tumor stroma cells. Our results argue that CAR-T therapy is capable of eradicating solid tumors through a combination of antigen-independent stroma destruction and antigen-specific tumor cell targeting.
