Bacillus thuringiensis (2010)

Bacillus thuringiensis (Bt) is a unique bacterium in that it shares a common place with a number of chemical compounds which are used commercially to control insects important to agriculture and public health. Although other bacteria, including B. popilliae and B. sphaericus, are used as microbial insecticides, their spectrum of insecticidal activity is quite limited compared to Bt. Importantly, Bt is safe for humans and is the most widely used environmentally compatible biopesticide worldwide. Furthermore, insecticidal Bt genes have been incorporated into several major crops, rendering them insect resistant, and thus providing a model for genetic engineering in agriculture.This review highlights what the authors consider the most relevant issues and topics pertaining to the genomics and proteomics of Bt. At least one of the authors (L.A.B.) has spent most of his professional life studying different aspects of this bacterium with the goal in mind of determining the mechanism(s) by which it kills insects. The other authors have a much shorter experience with Bt but their intellect and personal insight have greatly enriched our understanding of what makes Bt distinctive in the microbial world. Obviously, there is personal interest and bias reflected in this article notwithstanding oversight of a number of published studies. This review contains some material not published elsewhere although several ideas and concepts were developed from a broad base of scientific literature up to 2010.
Modeling 2D Appearance Evolution for 3D Object Categorization (2016)

3D object categorization is a non-trivial task in computer vision encompassing many real-world applications. We pose the problem of categorizing 3D polygon meshes as learning appearance evolution from multi-view 2D images. Given a corpus of 3D polygon meshes, we first render the corresponding RGB and depth images from multiple viewpoints on a uniform sphere. Using rank pooling, we propose two methods to learn the appearance evolution of the 2D views. Firstly, we train view-invariant models based on a deep convolutional neural network (CNN) using the rendered RGB-D images and learn to rank the first fully connected layer activations and, therefore, capture the evolution of these extracted features. The parameters learned during this process are used as the 3D shape representations. In the second method, we learn the aggregation of the views from the outset by employing the ranking machine to the rendered RGB- D images directly, which produces aggregated 2D images which we term as ``3D shape images". We then learn CNN models on this novel shape representation for both RGB and depth which encode salient geometrical structure of the polygon. Experiments on the ModelNet40 and ModelNet10 datasets show that the proposed method consistently outperforms existing state-of-the-art algorithms in 3D shape recognition.
Imaging of Particle Shear Migration With Electrical Impedance Tomography (1997)

Abstract Electrical impedance tomography is used to investigate the net migration of particles in a suspension undergoing pressure-driven flow through a tube at low Reynolds number. A low frequency electrical current is applied to the flowing suspension by two flush-mounted electrodes on the pipe wall to create a potential field which is sampled by other pairs of flush-mounted electrodes. A numerical inversion of the data, which takes into account the geometry and symmetry of the problem, gives the conductivity variation within the flow. An image of the suspension particle volume fraction in the tube is then formed using a relationship between the local conductivity and local suspension concentration. Consistent with particle shear migration of a concentrated suspension, the images from experimental data show a net migration of particles toward the centerline of the tube. The images favorably compare to an existing continuum theory of particle shear migration.
Antigens Associated with N‐ and L‐Type Calcium Channels in Lambert‐Eaton Myasthenic Syndrome (1995)

In Lambert-Eaton myasthenic syndrome neurotransmitter release is reduced by an autoimmune response directed against the calcium channel complex of the nerve terminal. Autoantibodies were detected by immunoprecipitation assays using solubilized receptors labeled with ligands selective for N-type (125I-omega conotoxin GVIA) and L-type ([3H]PN200-110) calcium channels. Sera with a high antibody titer (> 3 nM) against rat brain N-type channels contained autoantibodies that immunoprecipitated neuronal and muscle L-type channels. These IgG fractions stained a 55-kDa protein in immunoblots of purified skeletal muscle dihydropyridine receptor, suggesting that they contain autoantibodies against the beta subunit of the calcium channel. A distinct antibody population in the same fractions reacted with a nerve terminal 65-kDa protein that is unrelated to the beta subunit and displays properties similar to those of synaptotagmin.
Indoor Radio Map Construction Based on Crowdsourced Fingerprint Splitting and Fitting (2017)

Recently, crowdsourcing has been promoted as a promising solution for fingerprint-based indoor localization systems. However, when using crowdsourced fingerprints to construct an indoor radio map, the following challenges should be first addressed: inaccurate location information, nonuniform spatial density, fingerprint dimension diversity and collection device diversity. In this paper, we propose a radio map construction scheme based on crowdsourced fingerprint splitting and fitting to deal with the first three challenges. Our objective is to construct a grid radio map from crowdsourced fingerprints. We propose to split a crowdsourced fingerprint into several neighboring grid cells with some probability. For each grid cell, we propose to first filter out some unimportant features when composing a grid cell fingerprint. Furthermore, for a grid cell with very few or non supporting crowdsourced fingerprints, we propose to construct its fingerprint by using the surface fitting technique. We conduct field measurements and experiments to examine the localization performance. Results show that the proposed scheme can achieve 1.48m mean localization error and is more robustness to location annotation errors.
Abstract P3-10-35: Using Automated Image Analysis To Validate Ki67 as a Clinical Prognostic Biomarker for Estrogen-Receptor Positive Breast Cancers (2010)

Abstract Background: Ki67, an indicator of proliferation, has been shown to be a useful prognostic and predictive marker for breast cancer. Ki67 can be used to identify two distinct estrogen-receptor positive subtypes: luminal A and luminal B. Luminal A breast cancers have been identified as having a lower proliferation and better outcome compared to luminal B. Furthermore, early clinical trials suggest that Ki67 may be useful in identifying a subset of patients that are sensitive to adjuvant docetaxel treatment. Currently, only estrogen-receptor (ER), progesterone-receptor (PR), and human epidermal growth-factor (HER2) are routinely performed. We have optimized and validated an immunohistochemical (IHC) Ki67 assay and automated computerized image analysis platform for routine clinical testing. Materials and Methods: Immunohistochemical staining was quantitatively assessed using the ACIS® III platform on a cohort (N=761) of tamoxifen treated patients who were diagnosed with breast cancer in Calgary between 1990 and 2001. Tissue microarrays were constructed using three 0.6 mm cores. Ki67 results were available for 510 patients, 461 of which are ER/PR positive and HER2 negative. Staining was performed using the DAKO FLEX ready-to-use system. The percent nuclear area positive was calculated using ACIS III and the maximum value was used in statistical analysis Results: X-tile statistical software was used to identify an optimal Ki67 cut point to distinguish differential overall survival in node negative ER positive cancers of 18.75%. This cut point was then used to categorize the 461 ER/PR positive and HER2 negative breast cancers into luminal A (407; 88.3%) or luminal B (54; 11.7%) subtypes. The 8-year breast cancer specific survival was 85.2% (95% CI = 81.3% - 89.1%) for luminal A and 53.6% (95% CI = 39.3% - 67.9%) for luminal B (P&amp;lt;0.0001). Cox regression showed a hazard ratio of 1.63 (95% CI = 0.99 — 2.67, p=0.055), adjusting for age, tumor size, grade and lymph node status. Discussion: Quantification of Ki67 expression using automated image analysis can be used clinically to distinguish luminal A from luminal B in ER/PR positive and HER2 negative breast cancers. The purpose of this project was to develop a reliable Ki67 assay that can be easily adopted by other testing centers. Using a ready-to-use IHC system — such as DAKO FLEX — allows for consistent results between other clinical laboratories. Additionally, using an automated, quantitative imaging system — such as the ACIS® III — reduces inter-observer variation that can occur by human visual assessment.

Preliminary Investigation on Steel Jacketing Retrofitting of Concrete Bridges Half-Joints (2023)

An innovative strengthening system for dapped-end beams is studied numerically and experimentally in this paper. The system is developed for the half-joint regions of bridge beams also commonly called “gerber saddles”, but it can be adapted to different scenarios. The strengthening system consists of two steel plates that are clamped on both sides of the webs of the beams by means of bolts. The purpose of the system is to transfer the highest possible amount of shear from the concrete webs to the steel plate elements reducing the resistance demand of the concrete half joint. Shear is transferred by friction from concrete to steel plates. The system is designed to be applied on existing bridges without heavy work interesting the carriageway, therefore reducing the interference with the traffic. Some interesting considerations emerge from the study, including the influence of the flange web connection on the structural behavior and the possible presence of brittle failure mechanisms that are difficult to model numerically using f.e.m. simulations.

The Dbf4-Cdc7 Kinase Promotes Mcm2-7 Ring Opening to Allow for Single-stranded DNA Extrusion and Helicase Assembly (2014)

The replication fork helicase in eukaryotes is composed of Cdc45, Mcm2-7, and GINS (CMG). The Dbf4-Cdc7 kinase phosphorylates Mcm2 in vitro, but the in vivo role for Dbf4-Cdc7 phosphorylation of Mcm2 is unclear. We find that budding yeast Dbf4-Cdc7 phosphorylates Mcm2 in vivo under normal conditions during S phase. Inhibiting Dbf4-Cdc7 phosphorylation of Mcm2 confers a dominant-negative phenotype with a severe growth defect. Inhibiting Dbf4-Cdc7 phosphorylation of Mcm2 under wild-type expression conditions also results in impaired DNA replication, substantially decreased single-stranded formation at an origin, and markedly disrupted interaction between GINS and Mcm2-7 during S phase. In vitro, Dbf4-Cdc7 kinase (DDK) phosphorylation of Mcm2 substantially weakens the interaction between Mcm2 and Mcm5, and Dbf4-Cdc7 phosphorylation of Mcm2 promotes Mcm2-7 ring opening. The extrusion of ssDNA from the central channel of Mcm2-7 triggers GINS attachment to Mcm2-7. Thus, Dbf4-Cdc7 phosphorylation of Mcm2 may open the Mcm2-7 ring at the Mcm2-Mcm5 interface, allowing for single-stranded DNA extrusion and subsequent GINS assembly with Mcm2-7.
Potential of a Dried Rice/Mycelium Formulation of Entomopathogenic Fungi to Suppress Subterranean Pests in Small Fruits (1998)

The potential of a dried rice/mycelium formulation of three species of entomopathogenic fungi ( Metarhizium anisopliae, Beauveria bassiana and Paecilomyces farinosus ) was assessed according to five criteria: storage life, field efficacy against two subterranean pests of cranberry, persistence and efficacy against first-instar black vine weevil larvae in potted strawberry and field persistence in a cranberry bog. The number of conidia sporulated from the formulation did not decline between 4 and 20 days. In small plot field trials, the numbers of black vine weevil, Otiorhynchus sulcatus (F.), were significantly lower in plots treated with 1000 gm - 2 of formulated M. anisopliae than in untreated plots. In similar trials, the numbers of adult cranberry girdler, Chrysoteuchia topiaria (Zeller), inside emergence cages were significantly lower on plots treated with the formulated M. anisopliae than on untreated plots. The formulation suppressed first-instar black vine weevil larvae in potted strawberry regardless of the species of entomopathogenic fungus or the post-inoculation interval. M. anisopliae was periodically isolated for up to 637 days from plots in cranberry bogs treated with the formulation. In general, the dried rice/mycelium formulation may be a useful fungal mycopesticide for the management of subterranean pests of small fruits, especially if applied at high rates to areas of serious pest infestation.
Selective Fluorescence Quenching in Cationic Fluorene‐Thiophene Diblock Copolymers for Ratiometric Sensing of Anions (2013)

The cationic, all-conjugated AB diblock copolymer poly[9,9-bis(2-ethylhexyl)fluorene]-b-poly[3-(6-trimethylammoniumhexyl) thiophene] bromide (PF2/6-b-P3TMAHT) shows dual fluorescence from the poly(fluorene) (PF) and poly(thiophene) (PT) blocks. A comparison of fluorescence quenching of the cationic PT block fluorescence with unquenched PF block provides a sensitive ratiometric method for anion sensing. The application to analysis of halide ions, single- and double-stranded DNA is demonstrated. High selectivity is observed with halide ions, with the strongest quenching being seen with iodide. The quenching with DNA can be used for nucleic acid quantification at sub-μM concentrations.

cdma2000 Highly Detectable Pilot (2008)

Research and development on mobile phone positioning technologies are gaining momentum due to the potential in location based services. Mobile location is estimated based on measurements from satellites and terrestrial base stations. Satellite measurements often available in rural and suburban areas are less or not available in dense urban and indoor areas. Thus, base station measurements play an important role in mobile positioning. In this paper, we present the highly detectable pilot (HDP) that is being standardized in 3GPP2 for cdma2000 1xEV-DO. HDP allows mobile to detect significantly more base stations, and thus provides much better accuracy in location estimate.

Studies on a new variant of the Hermansky‐Pudlak syndrome: Qualitative, ultrastructural, and functional abnormalities of the platelet‐dense bodies associated with a phospholipase a defect (1978)

The structure and functions of platelets from a patient in whom albinism and hemorrhagic diathesis were associated have been investigated. Electron microscope studies showed a large reduction in the number of dense bodies and this was confirmed by an examination of fluorescent platelets loaded with mepacrine. The rare dense bodies were much bigger than normally observed; their density was diminished and was localized in a peripheral ring. Other platelet constituents were found to be normal. Platelet peroxidase activity was normal in the canaliculi of the dense tubular system; catalase-positive granules were also present. Serotonin uptake by the patient's platelets was much decreased and reserpine, a potent inhibitor of serotonin accumulation by normal human platelets, did not further decrease this incorporation. The uptake of free 14 C-arachidonic acid by the platelets was greatly diminished, as was its thrombin-induced liberation from phosphatidyl-choline and phosphatidyl inositol. Moreover, platelet phospholipase A1 activity was much reduced and phospholipase A2 activity was undetectable.
Fabrication factors influencing mechanical, moisture- and water-related properties of mycelium-based composites (2018)

Mycelium-based composites result from the growth of filamentous fungi on organic materials such as agricultural waste streams. These novel biomaterials represent a promising alternative for product design and manufacturing both in terms of sustainable manufacturing processes and circular lifespan. This study shows that their morphology, density, tensile and flexural strength, as well as their moisture- and water-uptake properties can be tuned by varying type of substrate (straw, sawdust, cotton), fungal species (Pleurotus ostreatus vs. Trametes multicolor) and processing technique (no pressing or cold or heat pressing). The fungal species impacts colonization level and the thickness of the air-exposed mycelium called fungal skin. Colonization level and skin thickness as well as the type of substrate determine the stiffness and water resistance of the materials. Moreover, it is shown that heat pressing improves homogeneity, strength and stiffness of the materials shifting their performance from foam-like to cork- and wood-like. Together, these results demonstrate that by changing the fabrication process, differences in performance of mycelium materials can be achieved. This highlights the possibility to produce a range of mycelium-based composites. In fact, it is the first time mycelium composites have been described with natural material properties.
A Modal Logic for Handling Behavioural Constraints in Formal Hardware Verification (2018)

<i>Moringa oleifera</i> L. was grown under cadmium and lead stress conditions and the variations in its mineral content, polyphenolics, and antioxidant activities were studied and how these heavy metals affect plant growth and development. In this study, the metal translocation factor was found <1 which indicates more metal accumulation in moringa roots than stem. A significant increase in enzymatic and non-enzymatic antioxidant activities was observed in leaves, stem, and roots under metal stress which shows moringa can withstand under metalliferous conditions by regulating its antioxidant system. Various parts of moringa plants exhibited good nutritional quality; even significant variation was recorded in nutritional attributes. A significant variation was also noted in the expression of polyphenolics in moringa stem, roots, and leaves which are indicators of plant defense system under abiotic stress conditions. The results of the present study clearly manifest that the nutritional quality and concentration of polyphenolics in moringa plants are least affected by cadmium and lead uptake. These findings suggested the cultivation of moringa plants on cadmium and lead affected soils which cannot only remediate soil metalliferous conditions but can also provide nutritious fodder for livestock. For better understanding of the involved mechansisms, there is need to study the genes which are associated with moringa tolerance under metalliferous conditions.
Laser Oscillation Near 5 μm, Based On Vibrational Emission From Fh(CN) Defects In Alkali Halide Crystals (1986)

The association of F-centers to CN defects in alkali halide crystals forms FH(CN) complexes which under excitation of their electronic absorption transitions in the visible produce optical emission from vibrationally excited CN- molecular states around 5 μm. In the host CsCl, with the most efficient F-center/CN- molecule coupling, laser oscillation has been obtained at temperatures up to 77 K on the three strongest vibrational emission transitions at 2000, 2025 and 2050 cm -1. Threshold pump powers are in the mW range.
