Differentiation of membrane excitability in isolated cleavage‐arrested blastomeres from early ascidian embryos. (1990)

1. Differentiation of excitable cells was studied electrophysiologically and histochemically in cleavage-arrested blastomeres isolated from early ascidian embryos. Blastomeres were isolated at the 4- or 8-cell stage, and cultured in sea water containing cytochalasin B until the time of hatching of control larvae. Electrical responses, immunoreactivity to epidermis-specific monoclonal antibody (2C5) and activity of muscle-specific acetylcholinesterase were examined. 2. All cleavage-arrested blastomeres isolated from an 8-cell embryo differentiated to elicit either muscular- or epidermal-type action potentials, but no neural-type action potentials were observed in these blastomeres. The anterior-animal and the posterior-animal blastomeres developed only epidermal-type action potentials, which involved expression of Ca2+ channels and immunoreactivity to 2C5. One-third of anterior-vegetal blastomeres developed epidermal-type action potentials which are mediated by Ca2+ channels though the immunoreactivity to 2C5 was absent. A majority of remaining blastomeres showed action potentials composed of Ca2+ currents and TEA-sensitive delayed K+ currents (type I response), and a few of them had fast transient K+ currents (A-currents) in addition (type II response). One-third of posterior-vegetal blastomeres developed epidermal-type action potentials without expression of the immunoreactivity to 2C5. The remainder differentiated into muscular-type cells, which expressed Ca2+ currents, TEA-sensitive and TEA-insensitive delayed K+ currents, and showed acetylcholinesterase activity. 3. Cleavage-arrested blastomeres isolated from a 4-cell embryo also differentiated into epidermal- or muscular-type cells, but not neural-type cells. The anterior blastomere, which is the parent cell of anterior-animal and anterior-vegetal blastomeres of an 8-cell embryo, developed epidermal-type, type I or type II responses, as was the case in the anterior-vegetal blastomere isolated from an 8-cell embryo. The posterior blastomere, which was the parent cell of posterior-animal and posterior-vegetal blastomeres of an 8-cell embryo, differentiated into either epidermal-type or muscular-type cells in terms of both membrane excitability and immunochemical reactivity. 4. Cleavage-arrested 1-cell embryos differentiated exclusively into epidermal-type cells in terms of membrane excitability and 2C5 immunoreactivity, even when the cytochalasin B concentration was decreased below 0.1 microgram/ml.(ABSTRACT TRUNCATED AT 400 WORDS)
Micelle Formation in Alkyl Sulfate Surfactants Using Dissipative Particle Dynamics (2018)

We use dissipative particle dynamics (DPD) to study micelle formation in alkyl sulfate surfactants, with alkyl chain lengths ranging from 6 to 12 carbon atoms. We extend our recent DPD force field [ J. Chem. Phys. 2017 , 147 , 094503 ] to include a charged sulfate chemical group and aqueous sodium ions. With this model, we achieve good agreement with the experimentally reported critical micelle concentrations (CMCs) and can match the trend in mean aggregation numbers versus alkyl chain length. We determine the CMC by fitting a charged pseudophase model to the dependence of the free surfactant on the total surfactant concentration above the CMC and compare it with a direct operational definition of the CMC as the point at which half of the surfactant is classed as micellar and half as monomers and submicellar aggregates. We find that the latter provides the best agreement with experimental results. Finally, with the same model, we are able to observe the sphere-to-rod morphological transition for sodium dodecyl sulfate (SDS) micelles and determine that it corresponds to SDS concentrations in the region of 300-500 mM.
An investigation of congestion dynamics in CCS networks during STP processor overload (2002)

The traffic carried by common channel signalling (CCS) networks is continually increasing. This, coupled with increasing complexity in services and customer profiles, results in potentially volatile traffic, and can lead to overload in various components of the CCS network. This paper investigates the dynamics of the national option with congestion priorities (NOCP) and international option (IO) congestion control strategies, when they are implemented in a CCS network during a period of signalling transfer point (STP) processor overload. In addition, we study the success of a combined control (CC) which incorporates both the NOCP and IO. We find (1) IO performs well under all the situations studied, and (2) the NOCP performs well in most cases, but is sensitive to the setting of congestion thresholds.
A Kondo insulating memristor (2012)

We report memristor behavior in a macroscopic bulk Kondo insulator Ce3Bi4Pt3 below 10 K. The ac current and voltage relation characteristic of memristors, pinched hysteresis loops which merge into a single line at high frequency, are systematically observed. A standard lock-in technique is used to probe the origin of this exotic behavior which cannot be explained solely by a static resistance drop arising from joule heating. Rather the response appears to be associated with the formation of dynamic thermal impedance in the dissipative regime.
Analysis of coating weight and iron content for iron-zinc alloy coatings by using X-ray fluorescence with multiple regression (2016)

Zinc-iron alloy coatings are produced by annealing of zinc-coated steels, in which the iron and the zinc are interdiffued to form iron-zinc alloy. The analysis of the coating weight and the iron content within the coating is very important since they are closely related to the corrosion properties. However, it is difficult to measure these alloy coatings by using the conventional X-ray fluorescence (XRF) method because iron is contained both in the coatings and the substrate. Furthermore, there is some concern that the non-uniform concentration of iron within the coatings may result in significant errors in the XRF analysis. The difference in probing depth for Zn Kalpha and Zn La lines can be used to separate the iron contained in the coating from that in the steel. The critical coating weights for the Zn Kalpha and the Zn Lalpha lines, were determined by fitting the line intensities of zinc electroplated coatings, and the coating weights of commonly produced zinc-iron alloy coatings were found to be higher than the critical coating weight, for the Zn Lalpha line and lower than that for, the Zn Kalpha line. A multiple regression method was successfully applied with the Zn Kalpha and the Zn La line intensities for the determination of the coating weight. The iron contents in the-coatings were determined by using the Zn Lalpha line only. With the proposed method, a coating weight accuracy to 0.57 g/m(2) and an iron content to 0.57 % was achieved for a number of commercially produced zinc-iron alloy coatings.
Introduction to law and literature: walking the boundary with Robert Frost and the Supreme Court (2007)

In April 1995 the American Supreme Court decided the case of Plaut v. Spendthrift Farm Inc. The case began in 1987 when Mr and Mrs Plaut and some other investors in Spendthrift Farm alleged that it had committed fraud and deceit when selling stock, contrary to Section 10(b) of the Securities and Exchange Act of 1934. The District Court in Kentucky held that this suit was time barred, following a recent Supreme Court decision in the case of Lampf which declared that such suits must be commenced within one year after the discovery of the facts constituting the violation and within three years of the violation itself. After this judgment became final, Congress enacted a new Section 27A(b) of the Securities and Exchange Act, providing that any action commenced before Lampf, but dismissed thereafter as time barred, could be reinstated. The Plauts moved for reinstatement accordingly, but the District Court held that Section 27A(b) was unconstitutional. This decision was confirmed by the Court of Appeal, and by the Supreme Court.
Effects of Some Organic Additives on Lithium Deposition in Propylene Carbonate (2002)

The effects of some film-forming organic additives, fluoroethylene carbonate (FEC), vinylene carbonate (VC), and ethylene sulfite (ES), on lithium deposition and dissolution were investigated in 1 M dissolved in propylene carbonate (PC) as a base solution. When 5 wt % FEC was added, the cycling efficiency was improved. On the contrary, addition of 5 wt % VC or ES significantly lowered the cycling efficiency. The surface morphology of lithium deposited in each electrolyte solution was observed by in situ atomic force microscopy (AFM). In the surface was covered with a uniform and closely packed layer of particle-like deposits of about 100-150 nm diam. The surface film seemed to be more solid in and inhomogeneous in From ac impedance measurements, it was revealed that the surface film formed in has a lower resistance than that in the additive-free solution, whereas that formed in or has a higher resistance. Large volume changes during lithium deposition and dissolution require that the surface film should be elastic (or soft) and be self-repairable when being damaged. In addition, a nonuniform current distribution is liable to cause dendrite formation, which requires that the surface film should be uniform and its resistance should be as low as possible. gave a surface film that satisfies all these requirements, and therefore only FEC was effective as an additive for deposition and dissolution of lithium metal. © 2002 The Electrochemical Society.

Decentralised congestion management of interconnected power systems (2002)

A method for the decentralised solution of the congestion management problem in large interconnected power systems is presented. The multi-area congestion management is achieved through crossborder co-ordinated redispatching by regional transmission system operators. The co-ordination is performed through a pricing mechanism inspired by Lagrangian relaxation. The prices used for the co-ordination of the regional subproblem solutions are the prices of electricity exchanges between adjacent areas. Test results from the application of the method to the three-area RTS96 are reported.
Acute Necrotizing Pancreatitis and Acute Suppurative Pancreatitis in the Cat (1993)

Abstarct Medical records and histologic sections of 40 cats with acute pancreatitis were reviewed. Two distinct groups of cats with pancreatitis were established by histologic analysis of tissue. Group I (32 cats) had acute pancreatic necrosis (APN). Group 2 (8 cats) had suppurative pancreatitis. Ages of affected cats ranged from 3 weeks to 16 years. l h e majority consisted of indoor cats of the Domestic Short-Haired breed but Siamese cats were over-represented relative to the general population (P&gt; 0.05). Twenty-two percent of cats were obese and 57%were underweight. Thirty-eight percent of cats had acute disease. In the other cats, two stages in the progression of the disease were evident: (1) anorexia. weight loss, and lethargy, followed by (2) acute deterioration, development of shock, and a moribund state, despite fluid therapy. The most common clinical signs were severe lethargy (100%), reduced appetite (97%), dehydration (92%), and hypothermia (68%). The initial hemogram occasionally showed a neutrophilia (30%) and anemia (2670)but packed cell volume (PCV) decreased markedly to the extent that 555% of cats were anemic terminally. Serum biochemical abnormalities included increased activities of A1, T (68%) and ALP (50%). and increased conrentrations of bilirubin (64%) and cholesterol (64%).Cats with APN were hyperglycemic (64%)), glycosuric (60%) and ketonuric (20%), whereas cats with suppurative pancreatitis tended to be hypoglycemic (7%). Renal failure and electrolyte abnormalities were mild or infrequent escept for hypokalemia (56%)).This study characterizes a severe necrotizing pancreatitis in the cat similar to that reported in other species, and a histologically distinct suppurative pancreatitis.
Mesenchymal stem cell therapy for the treatment of chronic obstructive pulmonary disease (2010)

Recent studies have revealed that adult stem cells such as bone marrow-derived cells contribute to lung tissue regeneration and protection, and thus administration of exogenous stem/progenitor cells may be a potent next-generation therapy for COPD. Pathogenesis of COPD is characterized by an upregulation of inflammatory processes leading to irreversible events such as apoptosis of epithelial cells, proteolysis of the terminal air-space and lung extracellular matrix components. The available pharmacological treatments are essentially symptomatic, therefore, there is a need to develop more effective therapeutic strategies. It has been previously demonstrated that transplanted MSC home to the lung in response to lung injury and adopt phenotypes of alveolar epithelial cells, endothelial cells, fibroblasts and bronchial epithelial cells. However, engraftment and differentiation are now felt to be rare occurrences and other mechanisms might be involved and play a more important role. Importantly, MSCs protect lung tissue through suppression of proinflammatory cytokines, and through triggering production of reparative growth factors. Accordingly, it is not clear if and how these cells will be able to repair, to slow or to prevent the disease. This article reviews recent advances in regenerative medicine in COPD and highlights that their potential application although promising and very attractive, are still a far away opinion.
Simple Approach to Superamphiphobic Overhanging Silicon Nanostructures (2010)

Superhydrophobic silicon nanostructures were fabricated by anisotropic etching of silicon coated with a thin hydrophobic layer. At certain etch parameters, overhanging nanostructures form at the apexes of the rod-shaped tips. This leads to superoleophobic behavior for several oily liquids with contact angles up to 152° and roll-off angle down to 8°. Such nonlithographic nanoscale overhanging structures can also be added to silicon nanograss by deposition of a thin SiO2 layer, which equips the silicon rods with 100−300 nm sized overhanging structures. This is a simple, fast, nonlithographic method for introducing amphiphobic behavior on a surface consisting of vertically aligned micro- or nanostructures.
Double window optimisation for constant time visual SLAM (2011)

We present a novel and general optimisation framework for visual SLAM, which scales for both local, highly accurate reconstruction and large-scale motion with long loop closures. We take a two-level approach that combines accurate pose-point constraints in the primary region of interest with a stabilising periphery of pose-pose soft constraints. Our algorithm automatically builds a suitable connected graph of keyposes and constraints, dynamically selects inner and outer window membership and optimises both simultaneously. We demonstrate in extensive simulation experiments that our method approaches the accuracy of offline bundle adjustment while maintaining constant-time operation, even in the hard case of very loopy monocular camera motion. Furthermore, we present a set of real experiments for various types of visual sensor and motion, including large scale SLAM with both monocular and stereo cameras, loopy local browsing with either monocular or RGB-D cameras, and dense RGB-D object model building.
Interaction of anti-cholesterol antibodies with human lipoproteins (1996)

Inoculation of mice with cholesterol-rich liposomes containing the adjuvant monophosphoryl lipid A results in the production of antiserum containing IgM Ab to cholesterol. The specificity of the Ab was to cholesterol and structurally similar sterols containing a 3 beta-hydroxyl group. Anti-cholesterol binding activity was significantly diminished if the 3 beta-hydroxyl was altered by either epimerization, substitution, oxidation, or esterification. A similar specificity for 3 beta-hydroxy-sterols was observed for an anti-cholesterol IgM mAb. Both hyperimmune serum and the mAb reacted with intact human very-low-/intermediate-density lipoprotein (VLDL/IDL) and low-density lipoproteins (LDL), but not high-density lipoproteins (HDL), in an ELISA, but could react with total lipid extracts containing cholesterol that were prepared from all three lipoprotein classes. Functionally, immune serum or the mAb aggregated and induced a fusion-like reaction with VLDL/IDL and LDL at low temperatures: these aggregates result in spherical structures visible with light microscopy. Similarly, binding of anti-cholesterol A to small cholesterol-rich liposomes resulted in the appearance of vesicular structures with approximately 20- to 200-fold increased diameters. These data demonstrate that the anti-cholesterol Ab recognize unesterified cholesterol in VLDL/IDL and LDL; high-density lipoprotein cholesterol in the intact lipoprotein, however, appears to be protected from reaction with these Ab.
Lip synchronization using speech-assisted video processing (1995)

We utilize speech information to improve the quality of audio-visual communications such as videotelephony and videoconferencing. In particular, the marriage of speech analysis and image processing can solve problems related to lip synchronization. We present a technique called speech-assisted frame-rate conversion. Demonstration sequences are presented. Other applications, including speech-assisted video coding, are outlined.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A wavelet transform method to merge Landsat TM and SPOT panchromatic data (1998)

Abstract To take advantage of the high spectral resolution of Landsat TM images and the high spatial resolution of SPOT panchromatic images (SPOT PAN), we present a wavelet transform method to merge the two data types. In a pyramidal fashion, each TM reflective band or SPOT PAN image was decomposed into an orthogonal wavelet representation at a given coarser resolution, which consisted of a low frequency approximation image and a set of high frequency, spatially-oriented detail images. Band-by-band, the merged images were derived by performing an inverse wavelet transform using the approximation image from each TM band and detail images from SPOT PAN. The spectral and spatial features of the merged results of the wavelet methods were compared quantitatively with those of intensity-hue-saturation (IHS), principal component analysis (PCA), and the Brovey transform. It was found that multisensor data merging is a trade-off between the spectral information from a low spatial-high spectral resolution sensor and the spatial structure from a high spatial-low spectral resolution sensor. With the wavelet merging method, it is easy to control this trade-off. Experiments showed that the simultaneous best spectral and spatial quality can only be achieved with wavelet transform methods, compared with the three other approaches examined.
Storage of haemopoietic stem cells for autologous bone marrow transplantation. (1995)

For reinfusing autologous bone marrow cells after high-dose chemotherapy and/or radiotherapy it is necessary that an effective technique for their storage is available. The traditional method uses 10% dimethyl sulphoxide as cryoprotectant, a rate-controlled computerized freezer programmed to cool the cells at a constant rate of 1 degrees C per minute and liquid nitrogen as the storage system. The method is time-consuming, expensive and requires technical expertise. Moreover, it is often associated with varying levels of clinical toxicity following infusion of the preserved cells. Processing the harvest to reduce the initial volume and the mature cells has been shown to be beneficial in reducing the volume of the cryoprotectant and the incidence of toxicity. An alternative, cost-effective method using a cryoprotectant mixture of 5% dimethyl sulphoxide, 6% hydroxyethyl starch and 4% albumin has been found to be effective even when the cells are stored at -80 degrees C without rate-controlled freezing. However, its efficacy needs to be evaluated for extended periods. The current use of purging and cell sorting methods seems to be promising.
Peptide Biomarker Discovery for Identification of Methicillin-Resistant and Vancomycin-Intermediate Staphylococcus aureus Strains by MALDI-TOF (2012)

Rapid identification of community-associated (CA) methicillin-resistant Staphylococcus aureus (MRSA), hospital-associated (HA) MRSA, and vancomycin-intermediate S. aureus (VISA) is essential for proper therapy and timely intervention of outbreaks. In this study, peptide biomarkers for rapid identification of methicillin-resistant and vancomycin-intermediate S. aureus strains were discovered by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. The results showed that the 1774.1 and 1792.1 m/z peaks corresponding to the phenol-soluble modulin α1 and phenol-soluble modulin α2 peptides, respectively, were present in the majority (95%, 121 of 127) of SCCmec types IV and V isolates, but only in 8% (15 of 185) of SCCmec types I-III isolates. Since SCCmec types I-III isolates are recognized as HA-MRSA and most CA-MRSA isolates belong to SCCmec types IV and V, these two peptides may serve as markers for discrimination between HA-MRSA and CA-MRSA isolates. The 1835.0 and 1863.0 m/z peaks were present in 50% (4 of 8) of heterogeneous VISA and 88% (14 of 16) of VISA isolates. The peptides of these two peaks were identified as proteolytic products of the acyl carrier protein. The results of this study provide the possibility to develop methods for identification of CA-MRSA, HA-MRSA, and vancomycin-resistant S. aureus isolates based on the presence of these peptides.
Incorporating augmented reality content in Engineering Design Graphics materials (2013)

This paper describes the development and integration of augmented reality content with traditional Engineering Design Graphics materials, and presents the results of a preliminary usability study conducted with Freshman Engineering students. The resources developed combine printed text and images with interactive three-dimensional content with the purpose of enhancing the understanding of technical graphics concepts and improving the students' visualization skills. In general, students had a very positive reaction when first presented with the materials and showed an optimistic attitude while interacting with the content. Additionally, augmented reality materials promote the development of self-directed learning skills and self-assessment.
