Modelling regime shifts in the southern Benguela: a frame-based approach (2011)

This study explores the usefulness of a frame-based modelling approach in the southern Benguela upwelling ecosystem, with four frames describing observed small pelagic fish dominance patterns. We modelled the dynamics of sardine Sardinops sagax and anchovy Engraulis encrasicolus populations under the influence of the small pelagic fishery and climate variability, performed extensive sensitivity analyses and exercised the model prototype in scenarios based on realistic management objectives. Model outputs were seen to roughly parallel observed dynamics. Frame dynamics were reasonably sensitive to frame switching rules. Reduced sardine recruitment in the ‘low’ frames had a strong negative impact on stock recovery, and bycatch of juvenile sardine from the modelled anchovy fishery could also greatly impair sardine recovery. Specific tests included exploring the robustness of fisheries management strategies under highly stochastic recruitment and uncertainty around long-term environmental forcing. The respective frame of the model is suggested as a composite indicator of ecosystem state. The model approach shows promise for evaluating small pelagic fisheries management strategies in an ecosystem context incorporating long-term environmental variability.
Low-Cost PMD-Insensitive and Dispersion Tolerant In-Band OSNR Monitor Based on Uncorrelated Beat Noise Measurement (2008)

A polarization-mode-dispersion-insensitive and dispersion tolerant in-band optical signal-to-noise-ratio monitor based on uncorrelated beat noise measurement is proposed and demonstrated. The proposed technique uses an optical delay line interferometer in recovering symmetrical signal samples and exploits the benefits of low-speed balanced receivers and digital signal processing in measuring the uncorrelated beat noise.

Comparison of elasticities of components of a cardiac bioprosthesis leaflet (1996)

The mechanoelastic behavior of calf pericardium employed in cardiac bioprostheses was compared with that of three types of thread (Nylon, Prolene, and silk) used to suture this biological tissue. The elastic limit (EL) of each material was determined by means of tensile tests and the mathematical functions that govern the stress/strain curves within the EL have been described. The first derivative of these functions for each point to the curves allowed the immediate calculation of the elastic modulus (EM), which was considered the best parameter for comparing the elasticities of the materials being assessed. It was observed that the deformation of the pericardium produced by the working stress of a pericardial leaflet was approximately 1000 times greater than that produced in the surgical threads. When the elasticities were compared on the basis of the EM, that of pericardium was 749.06, 626.95, and 1253.17 times greater than that of the Nylon, Prolene, and silk suture threads, respectively. These results demonstrate that the interaction between these materials (pericardium and the threads) could be generating detrimental forces that can diminish the durability of the leaflets of the bioprostheses constructed of calf pericardium. © 1996 John Wiley & Sons, Inc.
Nanoparticulate TiO<sub>2</sub>(B): An Anode for Lithium‐Ion Batteries (2012)

Small but powerful: TiO2(B) with the smallest particle size yet reported (2.5×4.3 nm) has been synthesized (see TEM image). Its volumetric capacity to store lithium, and hence charge, as an anode in a lithium-ion battery is greater than that of any other titanate at high rates (>1000 mA g−1).
High power 4.6 µm light emitting diodes for CO detection (1999)

We report on a powerful 4.6 µm light emitting diode (LED), operating at room temperature, suitable for carbon monoxide gas detection. The source is based on a InAs0.55Sb0.15P0.30 /InAs0.89Sb0.11/InAs0.55Sb0.15P0.30 symmetrical double heterostructure with large band offsets. To improve performance, the InAs0.89Sb0.11 ternary material in the active region was purified by using rare-earth ion gettering during liquid phase epitaxial growth. A pulsed optical output power in excess of 1 mW at room temperature has been measured, making these emitters suitable for use in cost-effective instruments for the environmental monitoring of carbon monoxide.
Synthesis of Sulfonic Acid Derivatives by Oxidative Deprotection of Thiols Using <i>tert</i>-Butyl Hypochlorite (2013)

Starting from alkyl halides or Michael acceptors, thioacetates were prepared in situ and further treated with t-BuOCl, affording the corresponding sulfonyl chlorides which were trapped with nucleophiles such as water, alcohol, or amines. The three steps can be achieved in a one-pot procedure. Oxidative deprotection also proved to be efficient with S-trityl and S-tert-butyl groups, making it a convenient route toward cysteic acid derivatives.
Control of large space structures using GPS—modal parameter identification and attitude and deformation estimation (2002)

Abstract This paper proposes a method for identifying the modal parameters of large space structures and estimating their attitude and deformation using kinematic GPS. The Eigensystem Realization Algorithm method is used for the modal parameter identification, and for attitude and deformation estimation, we adopt the Kalman filter based on the identified system dynamics. The proposed method was evaluated through computer simulations and in ground‐based experiments, and the results confirmed its feasibility. © 2002 Wiley Periodicals, Inc.

Chronically Administered Acetaminophen and the Ischemia/Reperfused Myocardium (2003)

Male and female Hartley strain guinea pigs weighing 280 +/- 10 g were given acetaminophen-treated water ad libitum for 10 days. Sham-treated control animals were given similar quantities of untreated tap water (vehicle-treated control group). On Day 10, hearts were extracted, instrumented, and exposed to an ischemia (low-flow, 20 min)/reperfusion protocol. Our objective was to compare and contrast ventricular function, coronary circulation, and selected biochemical and histological indices in the two treatment groups. Left ventricular developed pressure in the early minutes of reperfusion was significantly greater in the presence of acetaminophen, e.g., at 1 min, 40 +/- 4 vs 21 +/- 3 mmHg (P < 0.05). Coronary perfusion pressure was significantly less from 3 to 40 min of reperfusion in the presence of acetaminophen. Creatine kinase release in vehicle-treated hearts rose from 42 +/- 14 (baseline) to 78 +/- 25 units/liter by the end of ischemia. Corresponding values in acetaminophen-treated hearts were 36 +/- 8 and 44 +/- 14 units/liter. Acetaminophen significantly (P < 0.05) attenuated release of creatine kinase. Chemiluminescence, an indicator of the in vitro production of peroxynitrite via the in vivo release of superoxide and nitric oxide, was also significantly attenuated by acetaminophen. Electron microscopy indicated a well-preserved myofibrillar ultrastructure in the postischemic myocardium of acetaminophen-treated hearts relative to vehicle-treated hearts (e.g., few signs of contraction bands, little or no evidence of swollen mitochondria, and well-defined light and dark bands in sarcomeres with acetaminophen; opposite with vehicle). We conclude that chronic administration of acetaminophen provides cardioprotection to the postischemic, reperfused rodent myocardium.

Expression and reconstitution of a biologically active mouse interferon gamma receptor in hamster cells. Chromosomal location of an accessory factor. (1991)

In order to localize the chromosome encoding the accessory factor required for function of the murine interferon gamma (IFN-gamma) receptor, we transfected a cDNA expression vector encoding the receptor into several Chinese hamster x mouse somatic cell hybrids. As mouse Chromosome 10 carries the gene which encodes the interferon gamma-receptor (Ifgr), we used somatic cell hybrids that lack this chromosome. The presence of mouse Chromosome 16 was required to generate a response to murine IFN-gamma as assayed by stimulation of class I major histocompatibility complex antigen expression. These results demonstrate a species-specific accessory factor encoded on mouse Chromosome 16 (termed Ifgt) is necessary for mouse IFN-gamma to stimulate major histocompatibility complex expression through its receptor.
Fe 2<i>p</i> Core-Level Spectra for Pure, Epitaxial <i>α</i>-Fe2O3(0001), <i>γ</i>-Fe2O3(001), and Fe3O4(001) (1998)

We have measured high-energy resolution Fe 2p and O 1s photoemission spectra and high-angular resolution Fe 2p and O 1s photoelectron diffraction angular distribution for the following iron oxide films grown by molecular beam epitaxy: α-Fe2O3/α-Al2O3(0001), γ-Fe2O3/MgO(001), and Fe3O4/MgO(001). The combination of these two techniques allows the crystallinographic quality of the near-surface region to be determined for each phase prior to measurement and interpretation of the core-level spectra. These spectra thus constitute state-of-the-art energy-resolved data on phase-pure, crystallographically well-defined iron oxides.
Argentation resin chromatography of diterpene resin acids (1981)

Abstract Argentation chromatography with silver ion macroreticular ex‐change resin was applied to diterpene resin acids and methyl esters. Best results for diterpene acids were obtained with silver‐saturated ion exchange resin and solvent systems such as ethyl ether/acetone or acetone. The technique was applied in the isolation of a major component, identified as 20‐nor‐5,7,9‐abietatrien‐18‐oic acid, from a commercial disproportionated rosin.
Estimation of moisture in undried wheat and barley by near infrared reflectance (1985)

Abstract The potential of near infrared reflectance spectroscopy for estimating moisture in undried wheat and barley was investigated. Calibrations were developed for use with wholegrain (13–20% moisture) and coarsely‐ground grain (13–26% moisture) for both grain types. The performance (accuracy and precision) during the 1983 harvest of the calibrations involving coarsely‐ground grain (13–26% moisture) was superior to that of three moisture meters currently in commercial use in Ireland.
Revaluations (1993)

It is logical for the debased and commercialised mass culture to be replaced by a true culture for the masses. It cannot be forgotten that for the greater completeness of that culture the social and intellectual participation of the masses themselves must be secured. To achieve this a powerful amateur cultural movement must have been developed.1 Alan Lovell's brief article 'The Searchers and the Pleasure Principle',2 his critical positions in the revised Don Siegel American Cinema booklet and the paper by Jim Cook and Jim Hillier, The Growth of Film and Television Studies 1960–1975'3 mark the course of an important contemporary current in Film Studies. The current these articles signal is one of opposition to the way in which relations between culture, art and society had traditionally been made in Britain, and of espousal of the formula 'Popular Culture' that it is hoped will offer a potentiality for study of the cinema unvitiated by the governing principles of the British tradition of cultural studies; its élitism, conservatism, and individualism. Cook and Hillier construct the tradition thus: Crudely the position might be expressed as follows: modern society is unsatisfactory because its industrial mechanistic nature prevents it from meeting the essential human needs like contact with work, nature and other human beings; great art as the direct creative expression of the individual offers a critique of modern society and embodies accordingly moral values; since the mass media are products of technology, one of the most important features of the industrial system, they cannot possibly be art and are in fact corrupting in that they express false moral values.

The inhibitive effect of the pancreatic cancer cells mediating by shRNA targeting APRIL gene (2008)

Objective To investigate the inhibitive effect of shRNA (short hairpin RNA) targeting APRIL gene on the pancreatic cancer cells in vitro and in vivo, in order to explore the feasibility of gene therapy for pancreatic cancer. Methods The LV-shAPRIL targeting APRIL gene had been constructed before, and was used to infect the CFPAC-1 cells. Cell proliferation and apoptosis were examined by MTT and flow cytometry. Then CFPAC-1 cells were used to construct the model of transplantation tumor into the nude mice, the tumor growth was assessed after LV-shAPRIL treatment. Results 96 hours after the LV-shAPRIL infection into CFPAC-1 cells, the cell proliferation was significantly inhibited when compared with control group and lentivirus infection group (P＜0.05 ). Flow cytometry showed the apoptosis ratio of the CFPAC-1 cells was (17.35±0.96)% in LV-shAPRIL group, which was higher than that in control group and lentivirus infection group (P＜0.05 ). After LV-shAPRIL injection into the model of nude mice, the tumor growth was slower than that in the two control groups. The tumor's volume of the LV-shAPRIL group was(821.8±123.3) mm3 and the mass was (2.16±0.18)g at 27 day, and were obviously depressed, when compared with two control groups (P±0.05). Conclusions LV-shAPRIL targeting APRIL gene can inhibit the growth of the CFPAC-1 cells in vitro and vivo. This may provide a new gene therapy approach for pancreatic cancer.

Self-supervised Spatio-temporal Representation Learning for Videos by Predicting Motion and Appearance Statistics (2019)

We address the problem of video representation learning without human-annotated labels. While previous efforts address the problem by designing novel self-supervised tasks using video data, the learned features are merely on a frame-by-frame basis, which are not applicable to many video analytic tasks where spatio-temporal features are prevailing. In this paper we propose a novel self-supervised approach to learn spatio-temporal features for video representation. Inspired by the success of two-stream approaches in video classification, we propose to learn visual features by regressing both motion and appearance statistics along spatial and temporal dimensions, given only the input video data. Specifically, we extract statistical concepts (fast-motion region and the corresponding dominant direction, spatio-temporal color diversity, dominant color, etc.) from simple patterns in both spatial and temporal domains. Unlike prior puzzles that are even hard for humans to solve, the proposed approach is consistent with human inherent visual habits and therefore easy to answer. We conduct extensive experiments with C3D to validate the effectiveness of our proposed approach. The experiments show that our approach can significantly improve the performance of C3D when applied to video classification tasks.

Realization of an endoscope equipped with microprojection system for optogenetics (2012)

Optogenetics is the science where recent progresses in the field of photonics are combined with the techniques in molecular genetics to develop a methodology for modulation of neural activities.<sup>1-9</sup> Despite enormous enthusiasm in using optogenetics for brain studies, little has been done on the engineering side such as technology development for light delivery or realization of reliable systems for optical monitoring of the induced activities. In this project, we have implemented a Digital Micromirror Device based microprojection system capable of delivering illumination patterns through a high-resolution imaging fiber bundle that guides the pattern to the region of interest on the surface or within the brain tissue. The system is also equipped with an imaging path for detection of calcium signals and monitoring the induced patterns of cellular activities. A very interesting application of the system is extracting topographic computational maps of cortex or cellular receptive fields in-vivo. It is known that such maps are the engine of information processing in the cortex. Better understanding of the structure of such maps will help to unravel the mysteries of brain higher level computations. Another application of this system is related to the high-resolution stimulation patterns that cannot be produced with electrode arrays. Production of high-resolution patterns is important in the study of specific modes of brain activities. We report the details of our optical design, preliminary results produced by testing the system on tissue, and we discuss our strategy to extract new data from the brain tissue.
[Advancement in the methods for gene dosage analysis]. (2007)

Gene dosage determination is increasingly important for the study of both genome variation and rearrangement associated with complex diseases. Large genomic duplications and deletions are increasingly found as the causes. Methods such as PCR or sequencing are usually qualitative rather than quantitative. Thus, these methods can not detect large genomic duplications or deletions. Therefore, searching for a gene dosage method which is reliable, sensitive and high-throughput becomes imperative. Many high-performance technologies have been developed for gene dosage analyses in the recent years. There are generally three categories of methods including cytogenetic, Southern or dot blotting, or PCR amplification. Recent development in these techniques have been introduced and discussed in this review, which will help people to choose a suitable method for different research.
Transcriptome-wide characterization of human cytomegalovirus in natural infection and experimental latency (2017)

The transcriptional program associated with herpesvirus latency and the viral genes regulating entry into and exit from latency are poorly understood and controversial. Here, we developed and validated a targeted enrichment platform and conducted large-scale transcriptome analyses of human cytomegalovirus (HCMV) infection. We used both an experimental hematopoietic cell model of latency and cells from naturally infected, healthy human subjects (clinical) to define the breadth of viral genes expressed. The viral transcriptome derived from experimental infection was highly correlated with that from clinical infection, validating our experimental latency model. These transcriptomes revealed a broader profile of gene expression during infection in hematopoietic cells than previously appreciated. Further, using recombinant viruses that establish a nonreactivating, latent-like or a replicative infection in CD34<sup>+</sup> hematopoietic progenitor cells, we defined classes of low to moderately expressed genes that are differentially regulated in latent vs. replicative states of infection. Most of these genes have yet to be studied in depth. By contrast, genes that were highly expressed, were expressed similarly in both latent and replicative infection. From these findings, a model emerges whereby low or moderately expressed genes may have the greatest impact on regulating the switch between viral latency and replication. The core set of viral genes expressed in natural infection and differentially regulated depending on the pattern of infection provides insight into the HCMV transcriptome associated with latency in the host and a resource for investigating virus-host interactions underlying persistence.
Vision based rail track extraction and monitoring through drone imagery (2017)

Track detection and gauge measurement are considered as crucial aspects of railway inspection systems. Traditionally, monitoring by human inspectors was done. Nowadays, computer vision-based systems are used due to their flexibility and ease of use. In recent years, various prototypes of vision based inspection system have been proposed, most have a camera mounted on carts or trains. Employing drones for such monitoring systems provides a cost effective and accurate means for monitoring tracks. This paper explores the possibilities of computer vision based monitoring through drone imagery. The experimental results ensure that the proposed method provides high reliability and accuracy.
Biogenesis of Blackcurrant (<i>Ribes nigrum</i>) Aroma (1986)

The terpene fraction of blackcurrants is largely responsible for its characteristic flavour and aroma. The biogenesis of terpenes present in blackcurrant fruit has been studied by analysis of the volatile oils during ripening of the fruit and by feeding experiments using (2-13C) mevalonate. Three blackcurrant cultivars, Ben Lomond, Baldwin and Wellington XXX were studied, Ben Lomond and Baldwin fruit showed very similar composition of terpene compounds, whereas in Wellington XXX fruit, the terpenes derived from the thujane skeleton were at greatly reduced levels. Changes in concentration of monoterpene hydrocarbons, alcohols and esters occurred mainly during the period of sugar accumulation, when a sharp decrease in the level of terpene hydrocarbons and an increase in monoterpene alcohols and esters was observed. Feeding experiments with (2-13C) mevalonate indicated parallel incorporation into all monoterpene hydrocarbons and monoterpene alcohols. The presence of monoterpene and aromatic glycosides have also been tentatively identified in blackcurrants for the first time.
Landmark mapping: a general method for localizing cysteine residues within a protein. (1989)

We describe a general method to locate the positions of cysteine residues relative to the amino terminus of a protein, using a modified chemical cleavage of the polypeptide backbone at cysteine. The cleavage reaction introduces the carbon atom of 14CN into the carboxyl-terminal fragment produced at each cleavage of the polypeptide chain. Peptides containing the amino terminus of the intact protein are not labeled; all other peptides are labeled at their amino termini. Partial cleavage of a protein followed by gel electrophoresis and autoradiography identifies a ladder of unlabeled peptides that maps positions of the cysteine residues relative to the protein amino terminus. To map individual proteins present in a complex mixture, the polypeptides are cyanolated in solution with 14CN, and the modified proteins are separated by discontinuous SDS/PAGE. The gel is stained, and the desired protein is excised, cleaved at cysteine within the gel slice, and mapped in the second dimension by gel electrophoresis. These techniques are demonstrated with proteins of known sequence containing from zero to five cysteine residues. The cysteine "landmark map" should be particularly useful in locating protein modifications, in questions of protein similarity, and in mapping functional domains. A strategy is also presented for locating other residues in the polypeptide, for which specific cleavage methods exist.
