Temperature dependence of bend- and twist-induced birefringence in a low-birefringence fiber (1988)

The temperature dependence of the bend- and twist-induced birefringence in LB600 low-birefringence fiber has been measured at lambda = 0.633 microm. The relative temperature dependence B = (1/beta)dbeta/dT of the bend-induced birefringence beta was found to be (5.7 +/- 0.2) x 10(-4) K(-1) over a temperature range from -5 to 70 degrees C. The relative temperature dependence A = (1/g)dg/dT of the twist-induced birefringence g was found to be (4.95 +/- 0.25) x 10(-4) K(-1) (between 22 and 150 degrees C). The measured values of A and B are in accordance with a relative temperature dependence (1/C)dC/dT of the stress-optic coefficient C equal to (4.2 +/- 0.2) x 10(-4) K(-1).
Inorganic−Organic Hybrid Compounds:  Synthesis, Structure, and Magnetic Properties of the First Organically Templated Iron Oxalate−Phosphite, [C<sub>4</sub>N<sub>2</sub>H<sub>12</sub>][Fe<sup>II</sup><sub>4</sub>(HPO<sub>3</sub>)<sub>2</sub>(C<sub>2</sub>O<sub>4</sub>)<sub>3</sub>], Possessing Infinite Fe−O−Fe Chains (2005)

A hydrothermal reaction of a mixture containing iron(II) oxalate dihydrate, phosphorus acid, piperazine, and water at 150 °C for 72 h gave light-yellow cubes of a new hybrid iron oxalate−phosphite, [C4N2H12][FeII4(HPO3)2(C2O4)3], I. The structure, formed by FeO6, HPO3, and oxalate building units, possesses infinite one-dimensional chains of Fe−O−Fe, formed by Fe2O10 dimers. The phosphite units are grafted to these chains, and the oxalate moieties bond with the iron center through in-plane and out-of-plane connectivity forming a three-dimensional structure with intersecting channels. The organic amine molecule occupies the middle of the channels. The connectivity between the phosphite units and the Fe−O−Fe chains resembles the tancoite structure. Magnetic investigations reveal that the iron is present in the +2 oxidation state and orders antiferromagnetically.
Spin-on silicon-nitride Films for Photo-lithography by RT Cure of Polysilazane (2010)

Perhydropolysilazane (PHPS) is widely used as high cure temperature pre-ceramic polymer. In this paper, we report the conversion of PHPS films into solvent insoluble amorphous-silicon-nitride at room temperature in an inert atmosphere by vacuum ultra-violet (VUV) exposure. The films were deposited using spin-coating and pre-baked at 80°C for 3 mins before VUV exposure. The FT-IR spectra show an increase in Si-N bonds, a large reduction in Si-H content and complete elimination of N-H on VUV exposure. The refractive index (RI) ∼2.1 and extinction coefficient (k) ∼0.45 at 193nm were calculated using Cauchy fitting of spectroscopic ellipsometry (SE) measurements. The extinction coefficient exhibits a linearly dependence on VUV exposure time, suggestive VUV exposure time can be used a parameter to control the optical parameters of the films. These films could be used as inorganic-BARC (bottom anti-reflection coating) for ArF photolithography and the results are in accordance with the ProLith simulations showing that film of thickness ∼22nm corresponding to the 1st minima of the swing curve is sufficient for pattern generation.
Regulatory Roles for IscA and SufA in Iron Homeostasis and Redox Stress Responses in the Cyanobacterium <i>Synechococcus</i> sp. Strain PCC 7002 (2006)

SufA, IscA, and Nfu have been proposed to function as scaffolds in the assembly of Fe/S clusters in bacteria. To investigate the roles of these proteins further, single and double null-mutant strains of Synechococcus sp. strain PCC 7002 were constructed by insertional inactivation of genes homologous to sufA, iscA, and nfu. Demonstrating the nonessential nature of their products, the sufA, iscA, and sufA iscA mutants grew photoautotrophically with doubling times that were similar to the wild type under standard growth conditions. In contrast, attempts to inactivate the nfu gene only resulted in stable merodiploids. These results imply that Nfu, but not SufA or IscA, is the essential Fe/S scaffold protein in cyanobacteria. When cells were grown under iron-limiting conditions, the iscA and sufA mutant strains exhibited less chlorosis than the wild type. Under iron-sufficient growth conditions, isiA transcript levels, a marker for iron limitation in cyanobacteria, as well as transcript levels of genes in both the suf and isc regulons were significantly higher in the iscA mutant than in the wild type. Under photosynthesis-induced redox stress conditions, the transcript levels of the suf genes are notably higher in the sufA and the sufA iscA mutants than in the wild type. The growth phenotypes and mRNA abundance patterns of the mutant strains contradict the proposed scaffold function for the SufA and IscA proteins in generalized Fe/S cluster assembly and instead suggest that they play regulatory roles in iron homeostasis and the sensing of redox stress in cyanobacteria.
Linezolid for the treatment of multidrug-resistant tuberculosis (2005)

In our experience, linezolid has been a valid alternative drug in the management of multidrug-resistant tuberculosis. The prolonged use of linezolid is frequently associated with toxicity, mainly anaemia and peripheral neuropathy, that requires special management.
Resource-aware stream management with the customizable dproc distributed monitoring mechanisms (2004)

Monitoring the resources of distributed systems is essential to the successful deployment and execution of grid applications, particularly when such applications have well-defined QoS requirements. The dproc system-level monitoring mechanisms implemented for standard Linux kernels have several key components. First, utilizing the familiar /proc filesystem, dproc extends this interface with resource information collected from both local and remote hosts. Second, to predictably capture and distribute monitoring information, dproc uses a kernel-level group communication facility, termed KECho, which is based on events and event channels. Third and the focus of this paper is dproc's run-time customizability for resource monitoring, which includes the generation and deployment of monitoring functionality within remote operating system kernels. Using dproc, we show that: (a) data streams can be customized according to a client's resource availabilities (dynamic stream management); (b) by dynamically varying distributed monitoring (dynamic filtering of monitoring information), appropriate balance can be maintained between monitoring overheads and application quality; and (c) by performing monitoring at kernel-level, the information captured enables decision making that takes into account the multiple resources used by applications.
Flurbiprofen versus ASA in influenza symptomatology: a double-blind study. (1986)

The effectiveness and safety of flurbiprofen 100 mg b.i.d. vs acetylsalicylic acid (ASA) 500 mg b.i.d. were evaluated in a 4-day double-blind study in 30 patients suffering from influenza. The antipyretic effect of flurbiprofen was similar to that of ASA. Upper and lower respiratory symptoms, gastrointestinal symptoms, articular and muscular pain and asthenia were improved by both drugs. Only one patient on ASA discontinued the treatment.

Parked Cars as Virtual Network Infrastructure (2017)

Vehicular networks are envisioned to cover various use cases from safety related applications to infotainment. While there exist standardized solutions for exchanging single messages in a geographical area, coping with longer lasting flows of messages is more difficult. Developed solutions may require high node densities for fast delivery or even require pre-installed infrastructure (e.g., road side units). In this paper, we present a concept where we exploit parked cars to form a virtual network infrastructure. In particular, we form clusters representing a virtual road side unit spanning a relatively large geographical area. To reduce the channel load, we select a subset of the parked cars as active gateways to the cluster. This is done in a way to ensure that the connectivity to the cluster is not impaired. We evaluate the proposed algorithm using the Car4ICT architecture, a concept that enables cars in smart cities to discover and use various kinds of services.
Comparison of an inductorless low-IF and zero-IF receiver for Bluetooth (2003)

Low-IF and zero-IF receiver architectures benefit from the high integration level and are well suited for low-cost Bluetooth single-chip solutions. The low power consumption and cost associated with zero-IF receivers contrast with simple DC offset compensation and reduced linearity requirements in low-IF receivers. Both architectures have been compared to find the best suited architecture for Bluetooth. The different receiver requirements like noise figure, compression and intercept points have been calculated and the building blocks were optimized. The receivers have been implemented in a 0.25 /spl mu/ CMOS process without on-chip coils in order to reduce crosstalk and die size for system-on-chip solutions. Comparison of the two realized LNA architectures, two mixers, Gm-C and active RC filters indicated the better suitability of the low-IF receiver for a CMOS implementation, due to the increased influence of 1/f-noise and the higher required even-order linearity in a zero-IF architecture.
Direct transformation of rodent fibroblasts by jaagsiekte sheep retrovirus DNA (2001)

Jaagsiekte sheep retrovirus (JSRV) is the causative agent of ovine pulmonary carcinoma, a unique animal model for human bronchioalveolar carcinoma. We previously isolated a JSRV proviral clone and showed that it was both infectious and oncogenic. Thus JSRV is necessary and sufficient for the development of ovine pulmonary carcinoma, but no data are available on the mechanisms of transformation. Inspection of the JSRV genome reveals standard retroviral genes, but no evidence for a viral oncogene. However, an alternate ORF in pol (orf-x) might be a candidate for a transforming gene. We tested whether the JSRV genome might encode a transforming gene by transfecting an expression plasmid for JSRV [pCMVJS21, driven by the cytomegalovirus (CMV) immediate early promoter] into mouse NIH 3T3 cells. Foci of transformed cells appeared in the transfected cultures 2-3 weeks posttransfection; cloned transformants showed anchorage independence for growth, and they expressed JSRV RNA. These results indicate that the JRSV genome contains information with direct transforming potential for NIH 3T3 cells. Transfection of a mutated version of pCMVJS21 in which the orf-x protein was terminated by two stop codons also gave transformed foci. Thus, orf-x was eliminated as the candidate transforming gene. In addition, another derivative of pCMVJS21 (pCMVJS21DeltaGP) in which the gag, pol (and orf-x) coding sequences were deleted also gave transformed foci. These results indicate that the envelope gene carries the transforming potential. This is an unusual example of a native retroviral structural protein with transformation potential.
Assessing Grief Among the Bereaved Elderly: A Review of Existing Measures (1989)

The assessment of grief in the elderly, bereaved population has received much attention in the research and clinical literature. Existing instruments vary widely in their complexity, the extent of their theoretical base and in the evidence of their reliability and validity for their intended uses. In this article, the authors describe important principles for the assessment of grief, and present a rating instrument for use in comparing potential measures for this assessment. Nine of the most widely cited measures are reviewed using this process. Their variations along critical dimensions of assessment quality are clearly demonstrated. The general status of available measures, and recommendations for using this rating process in specific clinical settings are discussed.
Soya milk exerts different effects on plasma amino acid responses and incretin hormone secretion compared with cows’ milk in healthy, young men (2016)

Apart from the well-known action of insulin, the mechanism by which soya and cows' milk improve postprandial glycaemia control was examined. In total, twelve healthy, young, Chinese men were studied on three separate occasions, in random order with isovolumetric (322 ml) control water, soya milk and cows' milk. Plasma total amino acid concentrations increased 30 min after test meals consumption and were higher after soya milk (230 %) and cow milk (240 %) consumption compared with water. Cows' milk ingestion induced higher branched-chain amino acids (BCAA) (40 %) than soya milk. Postprandial incretin concentrations increased after meal consumption. Cows' milk meal was accompanied by higher incremental AUC (iAUC) (170 %) for glucagon-like peptide-1 (GLP-1) compared with soya milk and control (P=0·06). However, glucose-dependent insulinotropic polypeptide (GIP) concentrations increased to significantly greater levels after soya milk consumption (iAUC 60 % higher) compared with cows' milk and control. Consumption of both soya and cows' milk with carbohydrates induced a similar reduction in glycaemic response through a different mechanism, beyond insulin action. Plasma amino acids (alanine and arginine), and incretins in particular (GIP was stimulated), may be involved in the hyperinsulinaemia after soya milk meals. However, BCAA and GLP-1 release may be responsible for the reduced glycaemia after cows' milk consumption by delaying gastric emptying. This could be the result of different milk protein/amino acid composition, but also differences in milk carbohydrate composition (i.e. lactose v. sucrose). It can be concluded that soya milk is a good alternative to cows' milk with regard to glycaemic regulation, with different mechanisms involved.
Lipids and Glucose in Type 2 Diabetes: What About the β-Cell and the Mitochondria? (2005)

In the September issue of Diabetes Care , Boden and Laakso (1) review various methods by which fatty acids and fat tissue promote the pathogenic process deteriorating to type 2 diabetes. They emphasize the effect of peripheral fat storage in muscle and liver on the development of insulin resistance and diabetes but neglect, however, to discuss the effect of fat deposition in and around the β-cell on β-cell function and apoptosis as a pathophysiologic event in the development of the disease.

In their review, Boden and Laakso mention only the increase in insulin secretion and glucose-stimulated insulin secretion (GSIS) in response to exposure to free fatty acids (FFAs). …
[Determination of hydrogen peroxide production by vaginal strains of Lactobacillus spp. isolated from healthy women]. (2001)

Hydrogen peroxide production was determined in 31 strains of Lactobacillus spp., isolated in healthy women. The Lactobacillus spp. Were plated onto Brucella agar containing tetramethyl-benzidine/TMB/and horseradish peroxidase. The plates were incubated under anaerobic conditions at 37 C for 2-3 days, after which the isolates were exposed to ambient air. The horseradish peroxidase in the midium oxidises the TMB in the presence of H202 to from a blue pigment in H2O2-producing colony. 93.3% of the women had H2O2-(+) Lactobacillus spp. and 6.6% had non-H2O2 producing Lactobacillus spp. We postulate that hydrogen peroxide producing Lactobacillus spp. Play the main role for the homeostases of the vaginal ecosystem. This method can easily be applied for the differentiation of H2O2-producing Lactobacillus spp. From non-H2O2 producing Lactobacillus spp.
A charge-coupled area image sensor and frame store (1973)

A two-dimensional three-phase charge-coupled array with 128 × 106 elements, that can serve either as a solid-state image sensor or as an analog serial memory, has been built. As an image sensor the device has been operated successfully in the frame transfer mode to yield 120 frames/s with 64 × 106 resolution elements. By using the whole array as an image sensor, pictures with 128 × 106 resolution elements have been obtained at 15 frames/s with tolerable smearing. In the memory mode the device can store a whole analog frame as produced by a companion device, or 13 568 bits of digital information. But for the latter application defect-free devices are mandatory. The design of the device, the various modes of operation, the quality of the results, some typical defects, and some further applications are discussed.
Molecular Pathways Mediating Liver Metastasis in Patients with Uveal Melanoma (2008)

Uveal melanoma arises from melanocytes located in the uveal tract of the eye and is the most common primary intraocular tumor in adults. Metastatic liver disease is the overwhelming cause of death in uveal melanoma patients, with almost 50% of patients developing liver metastases up to 15 years after diagnosis. Most of these patients do not present with any evidence of overt metastasis at the time of initial diagnosis although it is assumed that they have undetectable micrometastases. Currently, there are no therapeutic modalities to prevent or efficiently treat the metastatic disease in uveal melanoma patients. Recent discoveries have shed light on the molecular pathways that may contribute to the progression of liver metastasis. The aim of this review is to describe new insights into the genetic and molecular pathways that may play a role in the development of liver metastases in uveal melanoma patients.
In Vitro and In Vivo Uncaging and Bioluminescence Imaging by Using Photocaged Upconversion Nanoparticles (2012)

Trading up: A bioimaging system that is based on caged D-luciferin/upconversion nanoparticle conjugate has been developed. The nanoparticles upconvert near-infrared light into UV light, which triggers the photorelease of D-luciferin (see scheme) and leads to enhanced fluorescence and bioluminescence signals in vitro and in vivo. The use of near-infrared light enables deep penetration into tissue in vivo with minimum cellular damage. Detailed facts of importance to specialist readers are published as ”Supporting Information”.

Aspects of Infamia (2006)

This thesis examines the development of the legal concept of infamia in Roman law. The first chapter examines the legal sources for studying Roman law, in particular the Corpus Iuris Ciuilis in order to establish the degree to which they may be relied upon in establishing the law of earlier periods, in particular the period from the late Republic until the reign of Diocletian. A cautiously optimistic conclusion is drawn about the degree to which these sources may be used to establish classical law. A synchronic study is then undertaken of infamia as it appears in the Corpus Iuris Ciuilis, focusing on the terms used to describe persons who are infames and the consequences of infamia. The understanding of infamia gained from this examination is then compared with the concept of infamia that appears in the Codex Theodosianus and in the Roman law-based barbarian codes to provide some guide as to the degree to which Justinian‟s compilers may have altered the law. It is argued that, in fact, there is little evidence for doctrinal change under the law of Justinian. The final Chapter adopts a more diachronic approach and attempts to trace back the cases and consequences of infamia established through the synchronic examination of the Justinianic Corpus. It is argued that a „core‟ of people can be identified for the classical period who were continuously subjected to the same legal disabilities that under Justian were embraced by the term infamia. However, it is also argued that infamia as a positive legal concept was a later development. Instead of using an umbrella concept like infamia, late Republican and early Imperial legal documents tended to list exhaustively persons subject to legal disabilities and what those disabilities were. The earliest appearance of infamia or a cognate in the legal sources is as a descriptive term of art for people who undergo certain legal disabilities under the edict, though the term itself was not in the edict. It is tentatively suggested that the existence of a recurring „core‟ of persons undergoing similar legal disabilities encouraged the expansion of the use of this term, which eventually enabled its use as a positive legal concept in later legal sources.
Numerical simulations and analytical analyses of the orbital capture manoeuvre as a part of the manipulator-equipped servicing satellite design (2012)

The lifetime of a considerable number of satellites is significantly shortened by malfunctions occurring during operational period; therefore, unmanned satellite servicing missions are considered. This paper presents an approach for analyses of various configurations and parameters of manipulator intended for on-orbit servicing. It is based on analytical method used to analyse workspace and singularities of the manipulator mounted on a free-floating satellite, and on numerical simulations of mission-specific manoeuvers (e.g., capture of malfunctioned satellite). The application of this approach to obtain parameters of the manipulator most suitable for defined servicing tasks is presented.
The predominant role of recently discovered tetrahydropyrimidines for the osmoadaptation of halophilic eubacteria (1992)

The aim of this investigation was to perform an extensive screening using HPLC and 13C-NMR spectroscopy to disclose the spectrum of osmolytes produced by aerobic heterotrophic and anoxygenic phototrophic eubacteria. The most predominant solutes detected within a wide range of marine and halophilic micro-organisms were two recently discovered tetrahydropyrimidines ectoine and hydroxyectoine, which were synthesized in response to osmotic stress.
