Rigorous modelling of irreversible non-linear polymerizations (1998)

This paper summarizes recent developmentsof a rigorous kinetic method for medelling of a non-linear irreversible polymerizations with a finite number of intramolecular cyclizations. Some Changes have been introduced in order to perform much more efficient computations with polyadditions. The procedure for obtainning z-averaged distributions of gyration radius for gaussian chain molecules is briefly described. Chain lengh distributions gel properties (such as the concentrations of elastically active junctions and chains) and average gyration radii were computed for non-radical copolymerization of monomers with one and with two terminal double bonds. Predictions of average molecular weights gelation for free radical copolymerization of that some kind monomers and vinyl acetate homopolymerization are also discussed.

Cardiomyocyte specific expression of the nuclear matrix protein, CIZ1, stimulates production of mononucleated cells with an extended window of proliferation in the postnatal mouse heart (2016)

Myocardial injury in mammals leads to heart failure through pathological cardiac remodelling that includes hypertrophy, fibrosis and ventricular dilatation. Central to this is inability of the mammalian cardiomyocyte to self-renew due to entering a quiescent state after birth. Modulation of the cardiomyocyte cell-cycle after injury is therefore a target mechanism to limit damage and potentiate repair and regeneration. Here, we show that cardiomyocyte-specific over-expression of the nuclear-matrix--associated DNA replication protein, CIZ1, extends their window of proliferation during cardiac development, delaying onset of terminal differentiation without compromising function. CIZ1-expressing hearts are enlarged, but the cardiomyocytes are smaller with an overall increase in number, correlating with increased DNA replication after birth and retention of an increased proportion of mono-nucleated cardiomyocytes into adulthood. Furthermore, these CIZ1 induced changes in the heart reduce the impact of myocardial injury, identifying CIZ1 as a putative therapeutic target for cardiac repair.
Restrictive lung disease in TNF-transgenic mice: correlation of pulmonary function testing and micro-CT imaging (2019)

<b>Purpose:</b> Micro-computed tomography (µCT) is increasingly being used on animal models as a minimally-invasive longitudinal outcome measure of pulmonary disease progression. However, while imaging can elucidate macroscopic structural changes over the whole lung, µCT is unable to describe the mechanical changes and functional impairments imposed by progressive disease, which can only be measured via pulmonary function tests (PFTs). The tumor necrosis factor-transgenic (TNF-Tg) mouse model of rheumatoid arthritis (RA) develops pulmonary pathology that mimics many aspects of the inflammatory interstitial lung disease (ILD) seen in a subset of patients with RA. Prior studies using µCT imaging of these mice found increased pulmonary density, characteristic of restrictive disease; however, there have been conflicting reports in the literature regarding the obstructive versus restrictive phenotype of this model. Our study looks to 1) define the functional impairments and 2) characterize the restrictive/obstructive nature of the disease found in this model. <b>Materials and Methods:</b> In this study, we performed PFTs at end-stage ILD, and paired these findings with µCT results, correlating radiology to functional parameters. TNF-Tg and WT littermates of both sexes underwent µCT imaging and PFT testing at 5.5 months-old. Spearman's correlation analyses were performed comparing lung tissue volume (LTV) to PFT parameters of gas exchange and tissue stiffness. <b>Results:</b> Compared to WT, TNF-Tg mice had impaired gas exchange capacity, increased respiratory resistance, and reduced lung compliance, elastance, and inspiratory capacity, indicating increased tissue stiffness and compromised pulmonary function. LTV was also consistently higher in TNF-Tg lungs. <b>Conclusions:</b> These findings demonstrate that: 1) TNF-Tg mice display a restrictive pathology, and 2) in vivo µCT is a valid outcome measure to infer changes in pulmonary mechanical and functional parameters.
Towards an optimised processing pipeline for diffusion MRI data: Effects of artefact corrections on diffusion metrics and their age associations in UK Biobank (2019)

Abstract Increasing interest in the structural and functional organization of the human brain in health and disease encourages the acquisition of big datasets consisting of multiple neuroimaging modalities accompanied by additional information obtained from health records, cognitive tests, biomarkers and genotypes. Diffusion weighted magnetic resonance imaging data enables a range of promising imaging phenotypes probing structural connections as well as macroanatomical and microstructural properties of the brain. The reliability and biological sensitivity and specificity of diffusion data depend on processing pipeline. A state-of-the-art framework for data processing facilitates crossstudy harmonisation and reduces pipeline-related variability. Using diffusion data from the UK Biobank we provide a comprehensive evaluation of different processing steps that have been suggested to reduce imaging artefacts and improve reliability of diffusion metrics. We consider a general pipeline comprising 7 post-processing blocks: noise correction; Gibbs ringing correction; evaluation of field distortions; susceptibility, eddy-current and motion-induced distortion corrections; bias field correction; spatial smoothing; and final diffusion metric estimations. Based on this evaluation, we suggest an optimised diffusion pipeline for processing of diffusion weighted imaging data.

TM1552 were isolated from the gut of the Formosan subterranean termite, Coptotermes formosanus. This is the first report of a genome sequence of a bacteriophage isolated from the termite gut.
Covert channel detection in VoIP streams (2011)

This paper presents two approaches to detect VoIP covert channel communications using compressed versions of the data packets. The approach is based on specialized random projection matrices that take advantage of prior knowledge about the normal traffic structure. The reduction scheme relies on the assumption that normal traffic packets belong to a subspace of smaller dimension or that can be included a convex set. We show that through the incorporation of this information in the design of the random projection matrices, the detection of anomalous traffic packets can be performed in the compressed domain with a slight performance loss with respect to the uncompressed domain. The validation of the detection algorithm is based on real data captured on a test bed designed to that end.
Avenanthramide-C reduces the viability of MDA-MB-231 breast cancer cells through an apoptotic mechanism (2017)

Breast cancer cells treated with AVN-C have a decrease in cell viability, an increase in the sub G<sub>1</sub> population, and stain positive for both annexin V and caspase activity, indicating that AVN-C induces apoptosis in breast cancer cells. These compounds may be able to act as chemotherapeutics as demonstrated through future in vivo studies.
All-numerical noise filtering of fluorescence signals for achieving ultra-low limit of detection in biomedical applications (2011)

We present an all-numerical method for post-processing of the fluorescent signal as obtained from labeled molecules by capillary electrophoresis (CE) in an optofluidic chip, on the basis of data filtering in the Fourier domain. It is shown that the method outperforms the well-known lock-in amplification during experiments in the reduction of noise by a factor of (square root)2. The method is illustrated using experimental data obtained during CE separation of molecules from a commercial DNA ladder with 17 fluorescently labeled molecules having different base-pair sizes. An improvement in signal-to-noise ratio by a factor of ∼10 is achieved, resulting in a record-low limit of detection of 210 fM.
Rapid nonlysosomal degradation of assembled HLA class II glycoproteins incorporating a mutant DR alpha -chain. (1990)

Gamma irradiation followed by antibody and complement selection was used to isolate a human B-lymphoblastoid cell line that no longer expresses HLA-DR molecules on its cell surface. Cell surface expression in the mutant (HMy2.DRN) was restored by transfecting a wildtype DRA but not a DRB cDNA, suggesting that a structural mutation in the DRA mRNA or protein was responsible for the lack of cell surface expression. Nucleotide sequence analysis of the DRA mRNA from HMy2.DRN revealed a 75 nucleotide deletion corresponding to the start of the alpha 2 domain and involving one of two cysteines that are involved in the formation of an intrachain disulfide bond. At the biochemical level, only minute quantities of HLA-DR could be precipitated from this cell line after a 4-h continuous label with 35S-methionine. HLA-DR beta and the class II-associated invariant chain could be seen coprecipitating with the mutant DR alpha-chain, suggesting a limited accumulation of normally assembled molecules. However, by carrying out the labeling at 16 degrees C instead of 37 degrees C, equivalent amounts of HLA-DR could be precipitated from parent and mutant alike. The mutant DR alpha chain was found in association with the beta-chain, but with reduced association with the invariant chain under these conditions. Pulse chase analysis in the parent and mutant cell lines indicated that this mutant DR alpha beta I complex undergoes a process of degradation at 37 degrees C. Inhibitors of intracellular transport such as monensin were ineffective in blocking this process of degradation. This work is consistent with published reports implicating the involvement of a pre-Golgi or an early Golgi compartment in the proteolysis of aberrantly folded or assembled multisubunit proteins.
Ultra wide band-stop MEFSS with metamaterial characteristic (2017)

In this paper, a new MEFSS with metamaterial characteristic is proposed and its band-stop response is achieved from 1GHz to 10GHz. The proposed broadband MEFSS unit consists of four split rectangles and one I-shaped strip printed on one side of silicon substrate with very compact size. The effective permittivity or effective permeability of MEFSS unit is negative, so MEFSS is a metamaterial structure and has a broadband frequency band gap in the entire UWB range.
Enabling Longer and Cheaper Subsea Tie-Backs Utilizing Local Subsea Chemical Storage and Injection (2018)

Abstract Strong economic drivers coupled with proper technical qualification of new equipment/methodologies are compulsory for industry adoption, especially with deepwater systems. This paper presents compelling economic findings from case study analysis that local, subsea chemical storage and injection can deliver significant savings compared to host platform storage and tube-based umbilical delivery. It then outlines a systematic approach developed for system qualification. Successful deployment of this new technology will greatly facilitate development of hundreds of smaller deepwater resources and billions of barrels (bbl) of oil equivalent (BOE) by enabling safe, cost-effective long distance tie-backs to existing infrastructure out of traditional reach of tube-based umbilicals.

Regulation of phenotypic transitions in the fungal pathogenCandida albicans (2012)

The human commensal fungus Candida albicans can cause not only superficial infections, but also life-threatening disease in immunocompromised individuals. C. albicans can grow in several morphological forms. The ability to switch between different phenotypic forms has been thought to contribute to its virulence. The yeast-filamentous growth transition and white-opaque switching represent two typical morphological switching systems, which have been intensively studied in C. albicans. The interplay between environmental factors and genes determines the morphology of C. albicans. This review focuses on the regulation of phenotypic changes in this pathogenic organism by external environmental cues and internal genes.
SF-36 scores in degenerative lumbar spine disorders: Analysis of prospective data from 451 patients (2006)

A Digital Internal Model Current Controller for Salient Machines (2020)

The performance of anisotropic electrical machines is strongly dependent on the current loop characteristics. The problems for achieving robustness and fast response, without overshoot and oscillations, are mainly related to different values and behavior of the direct and quadrature inductances (L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> , L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</sub> ), as well as to high output frequencies. In this article, a novel current controller structure based on internal model control method is presented, taking into account the magnetic anisotropy (L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> ≠ L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</sub> ). The model of salient machines is derived directly in the discrete domain and used to obtain a model-based controller. The controller derivation does not rely on transport-delay approximations, which enables improved decoupling of axes dynamics and the closed-loop robustness for very high output frequencies. The presented controller enables enhanced response for higher current loop bandwidth and output frequencies than the state-of-the-art methods. The experimental verification is performed on a three-phase synchronous machine, using a standard industrial three-phase inverter.
Functional connectivity of visual cortex in the blind follows retinotopic organization principles (2015)

Is visual input during critical periods of development crucial for the emergence of the fundamental topographical mapping of the visual cortex? And would this structure be retained throughout life-long blindness or would it fade as a result of plastic, use-based reorganization? We used functional connectivity magnetic resonance imaging based on intrinsic blood oxygen level-dependent fluctuations to investigate whether significant traces of topographical mapping of the visual scene in the form of retinotopic organization, could be found in congenitally blind adults. A group of 11 fully and congenitally blind subjects and 18 sighted controls were studied. The blind demonstrated an intact functional connectivity network structural organization of the three main retinotopic mapping axes: eccentricity (centre-periphery), laterality (left-right), and elevation (upper-lower) throughout the retinotopic cortex extending to high-level ventral and dorsal streams, including characteristic eccentricity biases in face- and house-selective areas. Functional connectivity-based topographic organization in the visual cortex was indistinguishable from the normally sighted retinotopic functional connectivity structure as indicated by clustering analysis, and was found even in participants who did not have a typical retinal development in utero (microphthalmics). While the internal structural organization of the visual cortex was strikingly similar, the blind exhibited profound differences in functional connectivity to other (non-visual) brain regions as compared to the sighted, which were specific to portions of V1. Central V1 was more connected to language areas but peripheral V1 to spatial attention and control networks. These findings suggest that current accounts of critical periods and experience-dependent development should be revisited even for primary sensory areas, in that the connectivity basis for visual cortex large-scale topographical organization can develop without any visual experience and be retained through life-long experience-dependent plasticity. Furthermore, retinotopic divisions of labour, such as that between the visual cortex regions normally representing the fovea and periphery, also form the basis for topographically-unique plastic changes in the blind.
Multi User Detection and Channel Estimation with Rotated Transforms for MC-CDMA (2003)

Abstract — In this paper we present an extension of the pure Walsh-Hadamard spreading sequences for MC-CDMA. By rotating the phase of the modulated signal before spreading, the signal space is exploited more efficiently. After the spreading the Euclidean distance of each superposed constellation is distributed more favorable in the signal space than without rotating. The novel approach of this paper combines the more favorable distributed Euclidean distance, caused by rotation, and a multiuser detector (MUD). A MUD does exploit the more favorable distributed Euclidean distance, which a single-user detector, like e.g. the MMSE, is not able to do. The novel combination of these two techniques offers up to 3 dB gain for 4-QAM in comparison to the non rotated Walsh-Hadamard sequences in an MC-CDMA system. I.
Deformation Modeling for Robust 3D Face Matching (2008)

Face recognition based on 3D surface matching is promising for overcoming some of the limitations of current 2D image-based face recognition systems. The 3D shape is generally invariant to the pose and lighting changes, but not invariant to the non-rigid facial movement, such as expressions. Collecting and storing multiple templates to account for various expressions for each subject in a large database is not practical. We propose a facial surface modeling and matching scheme to match 2.5D facial scans in the presence of both non-rigid deformations and pose changes (multiview) to a 3D face template. A hierarchical geodesic-based resampling approach is applied to extract landmarks for modeling facial surface deformations. We are able to synthesize the deformation learned from a small group of subjects (control group) onto a 3D neutral model (not in the control group), resulting in a deformed template. A user-specific (3D) deformable model is built by combining the templates with synthesized deformations. The matching distance is computed by fitting this generative deformable model to a test scan. A fully automatic and prototypic 3D face matching system has been developed. Experimental results demonstrate that the proposed deformation modeling scheme increases the 3D face matching accuracy.
