Elevated fasting triglycerides predict impaired glucose tolerance in adolescents at risk for type 2 diabetes (2006)

Objective: The aim of this study was to evaluate whether fasting laboratory values can predict impaired glucose tolerance (IGT) in adolescents who are at risk for developing type 2 diabetes mellitus (T2DM). Hypothesis: Elevated fasting triglycerides, a marker for worsening insulin resistance, predict risk for IGT. Design: Following a fast of at least 9 h, laboratory measures, body mass index (BMI), and demographic information were obtained. The subjects then underwent a 75-g oral glucose challenge with a 2-h postchallenge glucose determination. Subjects: Eighty-four adolescents aged 12–20 yr with at least two risk factors for developing T2DM (obesity, family history of T2DM, or acanthosis nigricans) and with either a fasting insulin level ≥25 μU/mL or a homeostasis model assessment of insulin resistance (HOMA-IR) ≥3.5 were recruited for the study. Results: Ten subjects (12%) had IGT [2-h glucose ≥140 mg/dL (7.77 mmol/L)], and 10 subjects (12%) had impaired fasting glucose [IFG; fasting glucose ≥100 mg/dL (5.55 mmol/L)]. However, only three (30%) subjects with IGT had IFG, though all subjects with IGT had a fasting triglyceride level ≥150 mg/dL (1.70 mmol/L). Of those subjects with elevated triglycerides, 29% had IGT. As a screening test to predict risk for IGT, elevated triglycerides >150 mg/dL had a sensitivity of 100% and a specificity of 68%. The positive predictive value was 29%, and the negative predictive value was 100%. Conclusions: Screening with fasting glucose alone would have missed 70% of subjects with IGT in this population of insulin-resistant adolescents. However, a fasting triglyceride level ≥150 mg/dL was strongly associated with IGT and may help to identify at-risk adolescents who should undergo formal glucose tolerance testing.
Donation to the National Collection of Insects (2007)

The National Collection of Insects has been donated the collection of the late Claude Courtois. This collection of 2500 specimens, mainly collected around Durban, will be a valuable addition to the NCI. We are already in possession of a large number of insects collected by Claude in Mauritius, which he donated about 30 years ago. The donation also included literature on the insects of Mauritius and reprints of Claude's own work on mosquito and snail control, to combat malaria and bilharzia. The obituary that follows was written by his son, Claude Courtois, of Johannesburg.
Risk Mitigation in Newsvendor Networks: Resource Diversification, Flexibility, Sharing, and Hedging (2007)

This paper studies how judicious resource allocation in networks mitigates risk. Theory is presented for general utility functions and mean-variance formulations and is illustrated with networks featuring resource diversification, flexibility (e.g., inventory substitution), and sharing (commonality). In contrast to single-resource settings, risk-averse newsvendors may invest more in networks than risk-neutral newsvendors: some resources and even total spending may exceed risk-neutral levels. With normally distributed demand, risk-averse newsvendors change resource levels roughly proportionally to demand variance, while risk-neutral agents adjust only proportionally to standard deviation. Two effects explain this operational hedge and suggest rules of thumb for strategic placement of safety capacity and inventory in networks: (1) Risk pooling suggests rebalancing capacity toward inexpensive resources that serve lower-profit variance markets. This highlights the role of profit variance (instead of demand variance) in risk-averse network investment. (2) Ex post revenue maximization suggests rebalancing capacity toward substitutable flexible but away from shared capacity when markets differ in profitability. Capacity imbalance and allocation flexibility thus mitigate profit risk and truly are operational hedges.

Genomic selection in plant breeding: from theory to practice (2010)

We intuitively believe that the dramatic drop in the cost of DNA marker information we have experienced should have immediate benefits in accelerating the delivery of crop varieties with improved yield, quality and biotic and abiotic stress tolerance. But these traits are complex and affected by many genes, each with small effect. Traditional marker-assisted selection has been ineffective for such traits. The introduction of genomic selection (GS), however, has shifted that paradigm. Rather than seeking to identify individual loci significantly associated with a trait, GS uses all marker data as predictors of performance and consequently delivers more accurate predictions. Selection can be based on GS predictions, potentially leading to more rapid and lower cost gains from breeding. The objectives of this article are to review essential aspects of GS and summarize the important take-home messages from recent theoretical, simulation and empirical studies. We then look forward and consider research needs surrounding methodological questions and the implications of GS for long-term selection.
Characteristics of Si <sub>3</sub> N <sub>4</sub> ‐SiO <sub>2</sub> ‐Ce <sub>2</sub> O <sub>3</sub> Compositions Sintered in High‐pressure Nitrogen (1983)

Full‐density Si 3 N 4 ‐SiO 2 ‐Ce 2 O 3 compositions were prepared by sintering with 2.5 MPa nitrogen pressure at temperatures of 1900° and 2090°C. Room‐temperature flexural strengths near 700 MPa for sintered material compared favorably with the strength of hot‐pressed material. At 1370°C, where flexural strengths as high as 363 MPa were obtained, it was observed that the coarsest structure was the strongest and the finest structure was the weakest. One of the compositions tested, Si 3 N 4 ‐8.7 wt% SiO 2 ‐8.3 wt%‐Ce 2 O 3 , was found to have excellent 200‐h oxidation resistance at 700°, 1000°, and 1370°C, without incidence of 700° to 1000°C phase instability and cracking.
THE IMPACT OF SUPPLY CHAIN COST ON THE PRICE OF THE FINAL PRODUCT (2014)

Nowadays, as consumption and production are growing enormously fast, companies are seeking for costs reduction aimed at ensuring competitiveness. In manufacturing companies, supply chain expenses play a colossal role in the cost of the final product. This paper focuses on the main processes in the logistics chain and their components. The authors analyse the relationship between the supply chain expenses and the price of the final product, the classification of logistics chain costs and their minimization as an assumption for the competitiveness of the final price.
Carbon plastics based on thermoplastic polyimide binders modified with nanoparticles (2016)

Polyimides (PIs) crystallized from melts are promising thermally stable, heat-resistant plastics with high destruction viscosities. Nanocomposites that in turn serve as matrixes for carbon plastics can be obtained on the basis of PIs filled with carbon nanoparticles of various structures and morphologies. The presence of the composite-in-composite structure gives rise to the enhancement of dissipation properties of the polymer matrix in particular and to an increase in the crack resistance of the carbon plastic in general.
Method for the Determination of Veratridine and Cevadine, Major Components of the Natural Insecticide Sabadilla, in Lettuce and Cucumbers (1997)

Sabadilla, an insecticide widely used by organic farmers, can be separated into five of its components (veratridine, cevadine, cevine, cevacine, and sabadine) by high-performance liquid chromatography (HPLC) and detected by atmospheric pressure chemical ionization liquid chromatography mass spectrometry (APCI/LCMS). Using APCI/LCMS in the selected ion monitoring mode as the determinative step, an analytical method has been developed for the detection and quantitation of the two largest sabadilla components, veratridine and cevadine, in lettuce and cucumbers spiked with veratrine. The insecticides are extracted with acetonitrile/water, and the extract is cleaned up by solid phase extraction (SPE) on a C-18 cartridge. The limits of detection (calculated at a signal to noise ratio of 10 to 1) of veratridine and cevadine in cucumbers and lettuce are 1−2 ppb, and the recoveries range from 74% to 101%. Keywords: Organic farming; sabadilla; veratridine; cevadine; cevine; cevacine; sabadine; high-performance liquid chromatography (HPLC); atmospheric pressure chemical ionization liquid chromatography mass spectrometry (APCI/LCMS)

Laser zone-melted Bi-Sr-Ca-Cu-O thick films (1989)

Directionally solidified superconducting Bi-Sr-Ca-Cu-O thick films have been fabricated by laser zone melting. Highly aligned grain structures were obtained. Films with no post-processing anneal showed Tc(R=0)=82 K and transport critical current densities Jc as high as 450 A/cm2 at 77 K and 5400 A/cm2 at 60 K. After annealing for 65 h at 850 °C, Tc increased to 85 K, and the best sample showed Jc =2200 A/cm2 at 77 K and 11 200 A/cm2 at 60 K.
Viewpoint switching in multiview videos using SP-frames (2008)

The distinguishing feature of multiview video lies in the interactivity, which allows users to select their favourite viewpoint. It switches bitstream at a particular view when necessary instead of transmitting all the views. The new SP-frame in H.264 is originally developed for multiple bit-rate streaming with the support of seamless switching. The SP-frame can also be directly employed in the viewpoint switching of multiview videos. Notwithstanding the guarantee of seamless switching using SP-frames, the cost is the bulky size of secondary SP-frames. This induces a significant amount of additional space or bandwidth for storage or transmission, especially for the multiview scenario. For this reason, a new motion estimation and compensation technique operating in the quantized transform (QDCT) domain is designed for coding secondary SP-frame in this paper. Our proposed work aims at keeping the secondary SP-frames as small as possible without affecting the size of primary SP-frames by incorporating QDCT-domain motion estimation and compensation in the secondary SP-frame coding. Simulation results show that the size of secondary SP-frames can be reduced remarkably in viewpoint switching.

A Woman and Poet against the Stream: Rachel Morpurgo, Advocate of the Kabbalah in an Anti-Kabbalistic Age (2015)

This essay deals with the defense of the Kabbalah by Triestine poet Rachel Morpurgo (1790–1871), in the context of the mid-nineteenth century controversy concerning the place of Jewish mysticism in modernity. Prominent Italian maskilic leaders in the Habsburg Empire rejected the validity of the Kabbalah and prioritized Jewish emancipation, for the sake of countering the challenge posed to Judaism by the “philosophical cast of modernity.” By defending the Kabbalah, Morpurgo struggled for her <i>différance</i> as a Jewish woman and poet. In <i>Sefer haberit</i> by Pinḥas Hurwitz and in the popularization of the Lurianic Kabbala as presented in Ḥayim Vital Calabrese’s <i>Sha‘arei kedushah</i>, Morpurgo found the key to legitimating her atypical gendered path and overcoming its marginalization in patriarchal culture. In defending the Kabbalah, she conceived a direction for renewing traditional patterns of Jewish thinking.
A Low-Cost Digital Matched Filter for Arbitrary Constant-Envelope Spread-Spectrum Waveforms (1984)

In this paper a noncoherent digital matched filter (DMF) with binary quantization is presented which shows good performance for arbitrarily angle modulated constant-envelope waveforms having large time-bandwidth products. The considered DMF represents an extension of the noncoherent DMF with one-bit digitization suggested previously by Turin for binary PSK signals. Analysis of the filter performance in the presence of white Gaussian noise results in a general expression which allows the output SNR of both DMF's to be calculated for any spread-spectrum waveform. Evaluating this expression reveals that the extended DMF can be matched to arbitrary waveforms having constant envelopes in such a way that the SNR loss with reference to the corresponding analog matched filter is less than 2.87 dB. The degradation is as low as 1.96 dB for waveforms with biphase or quadriphase signal samples such as binary PN-PSK, PNQPSK, and offset-PN-QPSK, but also PN-MSK. If both DMF's are applied to waveforms having complex valued envelopes, the extended DMF may outperform Turin's DMF by as much as 3 dB.
Modelling the Epidemiological Consequences of HIV Infection and AIDS: A Contribution from Operational Research (1990)

As part of the worldwide effort involved in modelling the spread of AIDS, nothing has been heard from the operational research community. Yet OR, with its client-oriented modelling philosophy, patently has a role to play in assisting clinicians, epidemiologists and health planners to obtain greater understanding of this staggering threat to public health. Using the methods of system dynamics, a model of the spread of AIDS in the UK homosexual population has been developed. It is implemented on a personal computer, and possesses the capability to capture complex virological and behavioural features of the epidemic whilst portraying the consequences in an easily digested graphical form. Some examples of these results are presented. The model's structure and parameters are also fully described, together with sensitivity tests on the crucial incubation time distribution.
Structural analysis of DEM's by intersection of surface normals in a three-dimensional accumulator space (2000)

This paper proposes a new methodology in DEM analysis in order to extract relevant information. The method proposed generates a set of 3D accumulators by using the DEM data. Each accumulator contains the number of intersections of the normals derived from the DEM surface. An alternative procedure has been developed in order to minimize the huge memory space required by a complete set of voxels. The principle consists of scanning the discrete space by a vertical plane. This plane, called a Voxel Wall, is composed of all the local accumulators. Two matrices are generated. In the first, named Values of the Accumulator Matrix (VAM), the positions x,y and the corresponding maximum value /spl mu/ of intersections encountered in each column of the Voxel Wall are registered. The depth /spl zeta/ of each /spl mu/ is coded on the second matrix, called Depth of the Accumulator Maxima (DAM). The results provided by regular shapes such as hemispheres, cones, and pyramids, as well as those produced by deformations and/or linear translations, are analyzed. An exhaustive interpretation of these results requires the creation of a catalogue of all the criteria for describing a given shape, whether it be isolated or not. The procedure has been applied to some "real" DEM containing volcanic edifices, crest lines, and bulging shapes.
The Genital Mycoplasmas (1980)

IT has been seven years since human infections with genital mycoplasmas were reviewed in these pages.1 Interest in these organisms has increased considerably with a corresponding increase in our knowledge about them. This article will attempt to evaluate critically this new information and to outline current concepts of the role of these organisms in human disease. For a more detailed consideration, we refer the reader to two recent reviews.2 , 3 In 1937, Dienes and Edsall4 reported the isolation of a mycoplasma, probably Mycoplasma hominis, from an abscess of Bartholin's gland. This was the first reported recovery of a mycoplasma from . . .
A double‐hurdle model of cigarette consumption (1989)

Abstract This paper shows the importance of the double‐hurdle approach for modelling individuals' cigarette consumption, using data from the UK General Household Survey, and argues that participation and consumption should be treated as separate individual choices. The likelihood function for the full double‐hurdle is derived, and it is shown how restrictions on the stochastic specification of the model and auxillary information, which identifies ex‐smokers, allow it to be decomposed. The empirical results highlight the value of the sample separation information and the need to model starting and quitting as separate decisions.

Propagation modelling for indoor wireless communication (1995)

It is important to characterise the indoor radio propagation channel to ensure satisfactory performance of a wireless communication system. Site measurements can be costly; propagation models have been developed as a suitable low-cost alternative. The existing models can be classified into two major classes: statistical models and site-specific propagation models. Statistical models rely on measurement data; site-specific propagation models are based on electromagnetic wave propagation theory. The ray-tracing technique is very useful in site-specific propagation modelling. This paper gives an overview of indoor propagation modelling and concentrates on a discussion of the ray-tracing modelling technique because of its practical appeal and its applicability to any environment.

Optimal Prefetching Scheme in P2P VoD Applications With Guided Seeks (2008)

Most existing peer-to-peer (P2P) video-on-demand (VoD) systems have been designed and optimized for the sequential playback. In practice, users often want to seek to the positions they are interested in. Such frequent seeks raise greater challenges to the design of the prefetching scheme. In this work, we first propose the concept of guided seeks. With the guidance, users can perform more efficient seeks to the desired positions. The guidance can be obtained from collective seeking statistics of other peers who have watched the same title in the previous and/or concurrent sessions. However, it is very challenging to aggregate the statistics efficiently, timely and in a completely distributed way. We design the hybrid sketches that not only capture the seeking statistics at significantly reduced space and time complexity, but also adapt to the popularity of the video. From the collected seeking statistics, we estimate the segment access probability, based on which we further develop an optimal prefetching scheme and an optimal cache replacement policy to minimize the expected seeking delay at every viewing position. Through extensive simulations, we demonstrate that the proposed prefetching framework significantly reduces the seeking delay compared to the sequential prefetching scheme.

NEUROPROTECTIVE EFFECTS OF DAURICINE AGAINST APOPTOSIS INDUCED BY TRANSIENT FOCAL CEREBRAL ISCHAEMIA IN RATS VIA A MITOCHONDRIAL PATHWAY (2007)

1. Previous experimental studies have shown that dauricine can protect the brain against ischaemic damage, but the underlying mechanisms remain unknown. In the present study, we examined whether dauricine inhibits neuronal apoptosis in the penumbra in a rat model of transient focal cerebral ischaemia. 2. Male Wistar rats underwent a 90 min temporary occlusion of the middle cerebral artery. Dauricine (21, 42 and 84 mg/kg) was administered by intragastric gavage twice a day for 3 days before ischaemia. Rats were killed and brain samples were collected 24 h after ischaemia. Histopathological outcome was evaluated by haematoxylin-eosin staining. Apoptotic changes were evaluated by terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labelling (TUNEL) for DNA fragmentation. The mitochondrial pathway was explored using immunohistochemistry for cytochrome c release, caspase 9 and caspase 3 activation, as well as by reverse transcription-polymerase chain reaction for determination of caspase 9 and caspase 3 mRNA expression. 3. Cytochrome c release, activation of caspase 9 and caspase 3 and DNA fragmentation were detected 24 h after ischaemia. Dauricine (42 and 84 mg/kg) pretreatment improved histopathological recovery, diminished DNA fragmentation and reduced cytochrome c release and activation of caspase 9 and caspase 3 in the penumbra at 24 h. 4. These findings suggest that dauricine attenuates apoptosis in the penumbra after transient focal cerebral ischaemia. The infarct-reducing effects of dauricine may be due, in part, to the inhibition of apoptotic cell death via a mitochondrial pathway in the penumbra.
Proline-Catalyzed Ketone-Aldehyde Aldol Reactions are Accelerated by Water (2004)

Proline-catalyzed aldol reactions between acetone or 4-thianone and different aldehydes are accelerated by addition of 1-10 equivalents of water to the reaction medium, allowing stoichiometric aldol reactions to proceed at acceptable rates.
