Low-complexity detection of zero blocks in wideband spectrum sensing (2015)

A low-complexity scheme for the reliable detection of zero blocks in a block sparse signal is proposed. The scheme is based on the application of verification based (VB) recovery algorithms in compressed sensing to block sparse signals, and is described in the context of wideband spectrum sensing (WSS). To apply VB algorithms to WSS, we devise a block sparse sensing matrix by designing a novel analog-to-information converter (AIC). The AIC, the sensing matrix and the VB algorithms are then optimized such that the largest number of zero blocks for a given number of measurements can be detected. This work introduces a new paradigm in the recovery of block sparse signals, where one is interested in partial detection of the complement of the support set, reliably, rather than the full recovery of the signal or its support. The analysis and simulations demonstrate significant improvement in performance/complexity over the existing block sparse recovery schemes within this new framework. An important application of the results would be in cognitive radios with limited computational resources.
National TAFE Day (2009)

The merits of Australia's TAFE system which imparts vocational education and training to students are discussed in the background of the first National TAFE Day to be celebrated on 28 October, 2009. A campaign against the privatisation of the vocational education system is called for, as also an increase in government funding for TAFE Institutes.
Colorimetric Tools for Solid-Phase Organic Synthesis (2004)

One of the unresolved problems of solid-phase organic synthesis (SPOS) is the availability of general and rapid methods to monitor the transformation of functional groups present in molecules supported on insoluble supports. Color tests, far from providing the ultimate solution, may help in detection (and sometimes in quantification) of different functional groups. In this short review, we have collected most of the methods available and applied in SPOS with an Experimental Section that describes the procedure we have successfully applied to bead analyses in our laboratories.
Stress Response in Infants Undergoing Cardiac Surgery: A Randomized Study of Fentanyl Bolus, Fentanyl Infusion, and Fentanyl-Midazolam Infusion (2001)

We demonstrated a significant endocrine stress response in infants with well compensated congenital cardiac disease undergoing cardiac surgery, but without adverse postoperative outcome. The use of large-dose fentanyl, with or without midazolam, with the intention of providing "stress free" anesthesia, does not appear to be an important determinant of early postoperative outcome.
Chemical Modification Produces Species-Specific Changes in Cucurbitacin Antifeedant Effect (2013)

Cucurbitacins are secondary metabolites that mediate insect plant interactions not only as allomones against generalists but also as kairomones for specialist herbivores. This study was undertaken to identify the potential of cucurbitacin derivatives as insect antifeedant agents. The antifeedant capacity against a Cucurbitaceae specialist [ Epilachna paenulata (Coleoptera: Coccinellidae)] and a polyphagous insect [ Pseudaletia adultera (Lepidoptera: Noctuidae)] was evaluated in preference tests in which the insects were given a choice between food plants either treated with the cucurbitacin derivatives or treated with the solvent. The activity was found not to be related to the basic cucurbitacin skeleton, as only 15 of the 28 tested cucurbitacin derivatives were active. Only one of the tested compounds was phagostimulant to the specialist insect (the hemissuccinate of 16-oxo-dihydrocucurbitacin B derivative), while all other active derivatives were deterrent against one of the insects (13 compounds) or both of them (3 compounds). Changes in ring A of the cucurbitacins, as well as in the side chain, modified the activity. As a general trend, when chemical modifications of the basic structure produced a change in activity, the response was opposite in both insects used as biodetectors, indicating that a selective variation in the activity may be achieved by chemical modifications of the cucurbitacin skeleton.
Antisense oligonucleotide therapy for the common Stargardt disease type 1-causing variant in ABCA4 (2022)

ABSTRACT The c.5461-10T&gt;C p.[Thr1821Aspfs*6,Thr1821Valfs*13] variant has been identified as the most common severe Stargardt disease type 1 (STGD1)-associated variant in ABCA4 . STGD1 is the most recurrent hereditary form of maculopathy and so far, no treatment is available for STGD1. In STGD1 patients homozygous for this variant, the onset of the disease typically is in childhood and patients are legally blind by early adulthood. The variant leads to exon skipping and generates out-of-frame ABCA4 transcripts that prevent the translation of functional ABCA4 protein. We applied antisense oligonucleotides (AONs) to restore the wild-type RNA splicing in ABCA4 c.5461-10T&gt;C. The effect of AONs was investigated in vitro using an ABCA4 midigene model and 3D human retinal organoids (ROs) homozygous for the ABCA4 c.5461-10T&gt;C variant. The mRNA in untreated ROs contained only disease-associated isoforms, whereas the organoids treated with the lead AON sequence showed 53% splicing correction and restoration of ABCA4 protein. Collectively, these data identified the lead candidate QR-1011 as a potent splice-correcting AON to be further developed as therapeutic intervention for patients harboring the severe ABCA4 c.5461-10T&gt;C variant.
The effects of proteins on the proton N.M.R. transverse relaxation time of water (1989)

The changes in water proton transverse relaxation behaviour induced by aggregation of Bovine serum albumin are explained in terms of the simple molecular processes of diffusion and chemical exchange without recourse to invoking changes in ‘bound’ water or the ‘state’ of water in the system. It is proposed that the main effect of aggregation is to reduce the protein proton transverse relaxation time because dipole-dipole interactions between protein protons are no longer as efficiently averaged by rotational motions, this in turn causes a reduction in water proton transverse relaxation time since water protons are in fast chemical exchange with protein protons. Diffusive exchange between water molecules then spatially averages the water proton signal to an extent that depends on the morphology of the aggregate-water system. The diffusive averaging process can give rise to multi-exponential relaxation.
Changes in Glucosinolate Concentrations in Brassica Crops B oleracea and B napus Throughout Growing Seasons (1996)

In the Iberian Peninsula, Brassicacrops are grown throughout the year and may be consumed at immature stages or leaves may be harvested by ‘picking-over’ during plant growth. Consumption of Brassicas in Portugal is high but there is no information on the levels of glucosinolates in such material. Changes in the total and individual glucosinolate concentrations of fourBrassica oleraceatypes (two cultivars of Portuguese cabbage, one Portuguese kale type and one hybrid white cabbage) and one PortugueseBrassica napustype were monitored throughout two growing seasons, spring/summer (SS) and summer/winter (SW). Glucosinolates were determined between sowing and maturity corresponding to nine sampling dates in the leaves and five harvests in the heads. The main glucosinolates inB oleraceatypes were 3-methylsulphinylpropyl-, allyl- and indol-3-ylmethyl- whereas in theB napustype pent-4-enyl-, 2-hydroxybut-3-enyl- and but-3-enylglucosinolate predominated. In the leaves ofB oleraceatypes, the highest concentration of total glucosinolates and of most of the individual glucosinolates was observed at 14 days after sowing whilst, in the heads the highest levels were noted at the start of head formation. In theB napus, the highest total and individual glucosinolate concentration was generally observed at the end of the growing season. Both for the total and for the main individual glucosinolates there were significant differences (P<0·001) between the nine harvest dates and between growing seasons. Between the two seasons, the glucosinolate levels in SS were generally higher than in SW. A comparison of cultivars showed the hybrid cabbage to have generally higher glucosinolate levels than the Portuguese types, except forB napus.
Analog floating-gate synapses for general-purpose VLSI neural computation (1991)

A floating-gate-based synapse structure for neural computing fabricated by a standard double-polysilicon CMOS process is presented. Simulation and experimental results on conductance programmability and charge retention demonstrate the capability of this programmable synapse circuit. With this circuit a neural chip of 100K synapses complexity can be constructed using one megabit static-RAM fabrication technologies.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Enrichment of the embryonic stem cell reprogramming factors Oct4, Nanog, Myc, and Sox2 in benign and malignant vascular tumors (2015)

These findings provide supporting evidence that enrichment for proteins involved in pluripotency is not restricted solely to malignant tumors as is suggested by the "stem cell theory of cancer", but additionally extends to common benign vascular tumors such as hemangiomas.
Endothelium-dependent responses in long-term human coronary artery bypass grafts. (1991)

In the present study, responses of long-term human coronary artery bypass grafts (CABGs) to known endothelium-dependent vasodilators, acetylcholine, calcium ionophore A23187, thrombin, and histamine, as well as authentic nitric oxide, the putative endothelium-derived relaxing factor, were studied. Sixteen CAGBs were isolated within 1-2 hours from hearts of 14 patients receiving a cardiac transplant. A total of 109 ring segments were prepared from these CABGs and studied in vitro. The duration of the CABGs ranged from 7 months to 12 years. Addition of acetylcholine (0.01-10 microM), calcium ionophore A23187 (0.01-1.0 microM), thrombin (0.01-1.0 unit/ml), and histamine (0.01-1.0 microM) consistently produced a dose- and endothelium-dependent relaxation, reaching a maximum of -35.3 +/- 3.3%, -45.3 +/- 5.5%, -26.9 +/- 4.8%, and -17.8 +/- 2.5% (mean +/- SEM), respectively. No significant difference was observed among the CABGs with different duration of transplantation, whereas the relaxant responses of different segments along the entire length of a CABG were markedly different. These latter differences in the endothelium-dependent responses appear to correlate inversely with the development of intimal proliferative lesions in these CABGs. Addition of nitric oxide (0.01-10 microM) produced a potent dose- and endothelium-independent relaxation, which was also slightly depressed in CABGs with severe intimal proliferation. These results demonstrate that long-term transplanted human saphenous vein grafts retain their endothelium-dependent responses and that development of severe intimal proliferative lesions, rather than the duration of the grafts, result in marked alterations in the reactivity of these transplanted CABGs.
Preoperative Statin Therapy Decreases Risk of Postoperative Renal Insufficiency (2010)

Preoperative statin therapy was associated with decreased incidence of postoperative renal insufficiency in patients undergoing cardiac surgeries, particularly in patients undergoing isolated CABG.
The role of RhoA-mediated Ca2+ sensitization of bronchial smooth muscle contraction in airway hyperresponsiveness (2004)

Smooth muscle contraction is mediated by Ca2+-dependent and Ca2+-independent pathways. The latter Ca2+-independent pathway, termed Ca2+ sensitization, is mainly regulated by a monomeric GTP binding protein RhoA and its downstream target Rho-kinase. Recent studies suggest a possible involvement of augmented RhoA/Rho-kinase signaling in the elevated smooth muscle contraction in several human diseases. An increased bronchial smooth muscle contractility, which might be a major cause of the airway hyperresponsiveness that is a characteristic feature of asthmatics, has also been reported in bronchial asthma. Here, we will discuss the role of RhoA/Rho-kinase-mediated Ca2+ sensitization of bronchial smooth muscle contraction in the pathogenesis of airway hyperresponsiveness. Agonist-induced Ca2+ sensitization is also inherent in bronchial smooth muscle. Since the Ca2+ sensitization is sensitive to a RhoA inactivator, C3 exoenzyme, and a Rho-kinase inhibitor, Y-27632, the RhoA/Rho-kinase pathway is involved in the signaling. It is of interest that the RhoA/Rho-kinase-mediated Ca2+ sensitization of bronchial smooth muscle contraction is markedly augmented in experimental asthma. Moreover, Y-27632 relaxes the bronchospasm induced by contractile agonists and antigens in vivo. Y-27632 also has an ability to inhibit airway hyperresponsiveness induced by antigen challenge. Thus, the RhoA/Rho-kinase pathway might be a potential target for the development of new treatments for asthma, especially in airway hyperresponsiveness.
Noncontact scanning electrical impedance imaging (2005)

We are interested in applying electrical impedance imaging to a single cell because it has potential to reveal both cell anatomy and cell function. Unfortunately, classic impedance imaging techniques are not applicable to this small scale measurement due to their low resolution. In this paper, a different method of impedance imaging is developed based on a non-contact scanning system. In this system, the imaging sample is immersed in an aqueous solution allowing for the use of various probe designs. Among those designs, we discuss a novel shield-probe design that has the advantage of better signal-to-noise ratio with higher resolution compared to other probes. Images showing the magnitude of current for each scanned point were obtained using this configuration. A low-frequency linear physical model helps to relate the current to the conductivity at each point. Line-scan data of high impedance contrast structures can be shown to be a good fit to this model. The first two-dimensional impedance image of biological tissues generated by this technique is shown with resolution on the order of 100 mum. The image reveals details not present in the optical image.
Deploy Mechanism for Virtual Machine Based Vehicular Ad Hoc Network Simulation (2020)

The virtual-machine (VM) based vehicular ad hoc network (VANET) simulation executes VMs as vehicles, on which actual telecom servers and routing protocols are implemented. We would like to create massive VM based VANET simulation to verify that VANET is feasible for emergency communication facility. However, network congestion increased with the number of VMs as the ad hoc network routing protocols created multiple network sessions over a certain part of physical machines. Such network congestion limited scalability.
Image Analysis Effects using Image Compression (2003)

The extensive adoption of digital imaging and image analysis has resulted in an explosion of digital image storage needs and the use of image compression algorithms in order to reduce the needs of computer storage media. Often, the user simply uses popular compression algorithms such as JPEG and chooses a level of compression that does not diminish the apparent quality to the human eye. The image is then often used to quantify morphological parameters using image analysis tools. In contrast, many users who frequently use image analysis will store digital images in formats that provide no compression (often referred to as "lossless" image reconstruction algorithms). This paper outlines considerations so that users of image analysis tools may tailor use of compression ratios to their types of images so that their storage needs may be greatly reduced while maintaining accurate morphological measurements.
An endothelium-derived hyperpolarizing factor distinct from NO and prostacyclin is a major endothelium-dependent vasodilator in resistance vessels of wild-type and endothelial NO synthase knockout mice (2000)

In addition to nitric oxide (NO) and prostacyclin (PGI(2)), the endothelium generates the endothelium-derived hyperpolarizing factor (EDHF). We set out to determine whether an EDHF-like response can be detected in wild-type (WT) and endothelial NO synthase knockout mice (eNOS -/-) mice. Vasodilator responses to endothelium-dependent agonists were determined in vivo and in vitro. In vivo, bradykinin induced a pronounced, dose-dependent decrease in mean arterial pressure (MAP) which did not differ between WT and eNOS -/- mice and was unaffected by treatment with N(omega)-nitro-l-arginine methyl ester and diclofenac. In the saline-perfused hindlimb of WT and eNOS -/- mice, marked N(omega)-nitro-l-arginine (l-NA, 300 micromol/liter)- and diclofenac-insensitive vasodilations in response to both bradykinin and acetylcholine (ACh) were observed, which were more pronounced than the agonist-induced vasodilation in the hindlimb of WT in the absence of l-NA. This endothelium-dependent, NO/PGI(2)-independent vasodilatation was sensitive to KCl (40 mM) and to the combination of apamin and charybdotoxin. Gap junction inhibitors (18alpha-glycyrrhetinic acid, octanol, heptanol) and CB-1 cannabinoid-receptor agonists (Delta(9)-tetrahydrocannabinol, HU210) impaired EDHF-mediated vasodilation, whereas inhibition of cytochrome P450 enzymes, soluble guanylyl cyclase, or adenosine receptors had no effect on EDHF-mediated responses. These results demonstrate that in murine resistance vessels the predominant agonist-induced endothelium-dependent vasodilation in vivo and in vitro is not mediated by NO, PGI(2), or a cytochrome P450 metabolite, but by an EDHF-like principle that requires functional gap junctions.
Hypermedia navigation support by fuzzy logic and neural networks (2002)

A system architecture for hypermedia applications is introduced that includes fuzzy logic and artificial neural networks (ANNs) for dynamically creating user-specific paths through a database of multimedia objects. A semantic data model is involved to describe the objects' characteristics. Fuzzy rules represent pedagogical knowledge whereas ANNs represent experiences and decisions of former users. During a session, the fuzzy rules and ANNs are used by a run-time controller in order to retrieve objects, which are appropriate candidates for continuing the way in the hypermedia network. This framework for navigation in hypermedia databases aims at increasing flexibility to adapt to each user's preferences, motivation and experiences.
Optical properties of undoped and Gd-doped CeO2 nanocrystalline thin films (2002)

The results of studies of the preparation, structure, and optical properties of undoped and Gd-doped CeO2 thin films are presented. Dense films with 4–150 nm grain size have been obtained on monocrystalline sapphire substrates using a polymeric precursor spin coating method. The results of the optical measurements are presented and correlated with the microstructure of the films. The transmission spectra have been used to determine the energy dependence of the refractive index, n and the extinction coefficient, k. Both n and k of the thin films decreased as grain size decreased and these results showed that this change could be related to the transition from crystalline to amorphous CeO2. The effect of dopant has little influence on n, &amp;lt;5%, but doping resulted in about a 30%–40% reduction of k compared to undoped specimens, which could be related to the decrease of absorption centers due to the replacement of Ce by Gd.

Simplified Method for Rooting Apple Cultivars in Vitro (1985)

Abstract Apple cultivar cuttings, prepared from shoots proliferated in vitro, initiated roots readily when placed for 3–7 days in the dark in a liquid medium containing only 43.8 m m sucrose and 1.5 μM indolebutyric acid (IBA). Raising the temperature during dark treatment from 25° to 30°C improved rooting for several cultivars. The addition of half-strength Murashige and Skoog (MS) salts or of phloroglucinol (PG) to the rooting medium did not improve rooting. IBA was the most effective auxin tried and indoleacetic acid (IAA) the least effective. Maintaining the cultures in the dark for more than 6 days improved rooting of only 1 cultivar and after 9 days rooting percentages sometimes decreased. More than 80% rooting was obtained with ‘McIntosh’ and ‘Mutsu’ after only 4 subcultures (4–5 months in culture), whereas some other cultivars in culture for a much longer time rooted no better or not as well. Roots that were initiated in liquid medium elongated after cuttings were inserted into preformed peat plugs. The resulting plantlets acclimated easily for transfer to greenhouse conditions.
Transdimensional Geoacoustic Inversion Using Prior Information on Range-Dependent Seabed Layering (2021)

This article proposes a transdimensional (trans-D) geoacoustic inversion method adapted to range-dependent (RD) propagation tracks based on prior information from a high-resolution seismic survey. Most trans-D inversions to date model the seabed as a stack of range-independent homogeneous layers, with unknown geoacoustic parameters and an unknown number of layers. The proposed method models the seabed as an unknown number of homogeneous sediment layers with an RD thickness structure and applies an adiabatic normal-mode model to predict acoustic propagation. To do so, the method extrapolates trans-D seabed models proposed at the receiver position over the range of the propagation track using reflector-interface information from a seismic survey. The method is applied successfully to modal time–frequency dispersion data collected over an RD track during the 2017 Seabed Characterization Experiment (SBCEX).

Biodegradation of Naphthalene-Contaminated Soils in Slurry Bioreactors (2001)

The effects of naphthalene concentrations and soil constituents (sand, clay, organic matter) on biodegrading naphthalene-contaminated soils using an acclimated Flavobacterium sp. were examined in continuously stirred slurry bioreactors. Soils with and without organic matter (1%) and kaolinite clay (20%) were used. Studies showed that sorption of naphthalene can be represented by the Freundlich isotherm. Among the soils investigated, clayey soil retarded the biodegradation process the most due to its desorption characteristics. Increasing the naphthalene contamination level from 500 mg/kg to 25,000 mg/kg doubled the biodegradation time in the slurry reactor with a soil loading of 10 g/L. A pseudo first-order kinetic was observed for naphthalene biodegradation, and the biodegradation constant was determined to be 0.20 mg/L/h. A kinetic model was developed to simulate the biodegradation of naphthalene in a continuously stirred batch slurry reactor and to understand the role of solubilization (solid phase naphthalene), desorption, and biodegradation in the removal of naphthalene. Predictions using the numerical model agreed with the experimental data.
