Upcycling of Packing-Peanuts into Carbon Microsheet Anodes for Lithium-Ion Batteries (2015)

Porous carbon microsheet anodes with Li-ion storage capacity exceeding the theoretical limit are for the first time derived from waste packing-peanuts. Crystallinity, surface area, and porosity of these 1 μm thick carbon sheets were tuned by varying the processing temperature. Anodes composed of the carbon sheets outperformed the electrochemical properties of commercial graphitic anode in Li-ion batteries. At a current density of 0.1 C, carbon microsheet anodes exhibited a specific capacity of 420 mAh/g, which is slightly higher than the theoretical capacity of graphite (372 mAh/g) in Li-ion half-cell configurations. At a higher rate of 1 C, carbon sheets retained 4-fold higher specific capacity (220 mAh/g) compared to those of commercial graphitic anode. After 100 charge-discharge cycles at current densities of 0.1 and 0.2 C, optimized carbon sheet anodes retained stable specific capacities of 460 and 370 mAh/g, respectively. Spectroscopic and microscopic investigations proved the structural integrity of these high-performance carbon anodes during numerous charge-discharge cycles. Considerably higher electrochemical performance of the porous carbon microsheets are endorsed to their disorderness that facilitate to store more Li-ions than the theoretical limit, and porous 2-D microstructure enabling fast solid-state Li-ion diffusion and superior interfacial kinetics. The work demonstrated here illustrates an inexpensive and environmentally benign method for the upcycling of packaging materials into functional carbon materials for electrochemical energy storage.
Unusual event detection in real-world surveillance applications (2014)

Given the near-ubiquity of CCTV, there is significant ongoing research effort to apply image and video analysis methods together with machine learning techniques towards autonomous analysis of such data sources. However, traditional approaches to scene understanding remain dependent on training based on human annotations that need to be provided for every camera sensor. In this thesis, we propose an unusual event detection and classification approach which is applicable to real-world visual monitoring applications. The goal is to infer the usual behaviours in the scene and to judge the normality of the scene on the basis on the model created. The first requirement for the system is that it should not demand annotated data to train the system. Annotation of the data is a laborious task, and it is not feasible in practice to annotate video data for each camera as an initial stage of event detection. Furthermore, even obtaining training examples for the unusual event class is challenging due to the rarity of such events in video data. Another requirement for the system is online generation of results. In surveillance applications, it is essential to generate real-time results to allow a swift response by a security operator to prevent harmful consequences of unusual and antisocial events. The online learning capabilities also mean that the model can be continuously updated to accommodate natural changes in the environment. The third requirement for the system is the ability to run the process indefinitely. The mentioned requirements are necessary for real-world surveillance applications and the approaches that conform to these requirements need to be investigated. This thesis investigates unusual event detection methods that conform with real-world requirements and investigates the issue through theoretical and experimental study of machine learning and computer vision algorithms.
Temperature and strain insensitive bend measurements with D-type fibre Bragg gratings (2000)

We present a new sensor configuration based on the intrinsic bend sensitivity of Bragg gratings written in D-type fibres. This sensor can be embedded in any layer of a composite material to evaluate curvature in a way independent of axial strain or temperature. It can also be used to measure other parameters such as acceleration, angle or acoustic pressure.
Regulator of G-protein signalling 2 mRNA is differentially expressed in mammary epithelial subpopulations and over-expressed in the majority of breast cancers (2007)

Molecular analysis of prospectively isolated mammary epithelial cells identified RGS2 as a modulator of oxytocin receptor signalling, which is highly expressed in the myoepithelial cells. The RGS2 gene, but not the oxytocin receptor, was also shown to be over-expressed in the majority of breast cancers, identifying the product of this gene, or the pathway(s) it regulates, as potentially significant therapeutic targets.
Directed mutagenesis of the Rhodobacter capsulatus puhA gene and orf 214: pleiotropic effects on photosynthetic reaction center and light-harvesting 1 complexes (1996)

Rhodobacter capsulatus puhA mutant strains containing either a nonpolar, translationally in-frame deletion or a polar insertion of an antibiotic resistance cartridge were constructed and evaluated for their photosynthetic growth properties, absorption spectroscopy profiles, and chromatophore protein compositions. Both types of mutants were found to be incapable of photosynthetic growth and deficient in the reaction center (RC) and light-harvesting 1 (LH1) complexes. The translationally in-frame puhA deletion strains were restored to the parental strain phenotypes by complementation with a plasmid containing the puhA gene, whereas the polar puhA mutants were not. Analogous nonpolar and polar disruptions of orf 214 (located immediately 3' of the puhA gene) were made, and the resultant mutant strains were evaluated as described above. The strain containing the nonpolar deletion of orf 214 exhibited severely impaired photosynthetic growth properties and had greatly reduced levels of the RC and LH1 complexes. Complementation of this strain with a plasmid that expressed orf 214 from the nifHDK promoter restored photosynthetic growth capability, as well as the RC and LH1 complexes. The polar disruption of orf 214 yielded cells that were incapable of photosynthetic growth and had even lower levels of the RC and LH1 complexes, and complementation in trans with orf 214 only marginally improved these deficiencies. These results indicate that orf 214 and at least one additional gene located 3' of orf 214 are required to obtain the RC and LH1 complexes, and transcription read-through from the puhA superoperon is necessary for optimal expression of these new photosynthesis genes.

Issues in the design and implementation of views in object-oriented databases (1990)

Summary form only given. Views have traditionally been a mechanism for coordinating access to shared data in a database. View definition schemes in relational databases have aimed at consistency with the conceptual model and the use of a limited view specification language that allows efficient and unambiguous translation of view updates. These goals are equally applicable to object-oriented databases (OODBs). Consequently, it makes sense to model views in OODBs as objects themselves. OODBs differ from relational databases in that they have notions of classes and instances, and allow nesting of both classes and instances. Thus the underlying theory of the object-oriented data model is graph based, in contrast to the relational theory, which is set based. Object-oriented views can be thought of as graph transformations applied to class or instance graphs in the underlying database. Depending on the nature of the underlying objects, views can be class-lattice views or complex object views. The exact set of graph transformations that can be applied to class or instance graphs needs to be limited to allow views to be virtualizable for querying purposes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis Gas Generation—Industrial (2010)

Synthesis gas is an important building block for a number of petrochemicals as well as an important feedstock for liquid fuels via the Fischer Tropsch route or as reducing gas for iron ore reduction.
Towards Electrochemical Artificial Muscles: A Supramolecular Machine Based on a One‐Dimensional Copper‐Containing Organophosphonate System (2004)

Robo copper: A mechanically robust corrugated sheet, 1 DOP-Cu, is composed of mats of individual chain-bundles joined by π–π interactive forces (see structure). Upon electrochemical charge injection into 1 DOP-Cu, the variations of the cell parameters of the Li-inserted phase were observed by X-ray diffraction. The mechanical deformation of the whole sheet is produced by a CuII/CuI redox process.

EFAB: High Aspect Ratio, Arbitrary 3-D Metal Microstructures Using a Low-Cost Automated Batch Process (1999)

Abstract EFAB (“Electrochemical FABrication”) is a new micromachining process utilizing an innovative “Instant Masking” (IM) technique to electrochemically deposit an unlimited number of metal layers for microfabrication. Through this approach, high-aspect-ratio microstructures with arbitrary 3-D geometry can be rapidly and automatically batch-fabricated at low temperature (&lt; 60 °C) using an inexpensive desktop machine. IC-MEMS integration can also be carried out by this low temperature process.
Japanese Encephalitis Virus Infection Initiates Endoplasmic Reticulum Stress and an Unfolded Protein Response (2002)

The malfunctioning of the endoplasmic reticulum (ER) of cells in hosts ranging from yeast to mammals can trigger an unfolded protein response (UPR). Such malfunctioning can result from a variety of ER stresses, including the inhibition of protein glycosylation and calcium imbalance. To cope with ER stresses, cells may rely on the UPR to send a signal(s) from the ER to the nucleus to stimulate appropriate cellular responses, including induction of chaperone expression. During Japanese encephalitis virus (JEV) infection, the lumen of the ER rapidly accumulates substantial amounts of viral proteins for virus progeny production. In the present study, we demonstrate that as evidenced by certain chaperone inductions, JEV infection triggers the UPR in fibroblast BHK-21 cells and in neuronal N18 and NT-2 cells, in which JEV results in apoptotic cell death. By contrast, no UPR was observed in apoptosis-resistant K562 cells infected by JEV. JEV infection also activates expression of CHOP/GADD153, a distinctive transcription factor often induced by the UPR, and appears to trigger activation of p38 mitogen-activated protein kinase, a posttranslational activator of CHOP. Ectopic enforcement of CHOP expression enhanced JEV-induced apoptosis, whereas treatment with a p38-specific inhibitor, SB203580, partially blocked JEV-induced apoptosis. Interestingly, bcl-2 overexpression and treatment with a pancaspase inhibitor, z-VAD-fmk, inhibited CHOP induction and diminished JEV-induced apoptosis, suggesting that Bcl-2 and caspases could be the upstream regulators of CHOP. Our results thus suggest that virus-induced ER stress may participate, via p38-dependent and CHOP-mediated pathways, in the apoptotic process triggered by JEV infection.
A cross-layer design for P2P live streaming with graceful handover in mobile IP network (2013)

With the development of wireless network and rapidly increasing requirements for mobile computing, peer-to-peer technology on Mobile IP (Mobile P2P) becomes a new focus. Mobile P2P is a more and more interested topic for live streaming in next generation. However, the direct porting of existing P2P application on Mobile IP is difficult to overcome time-critical limitation. Handover under Mobile IP usually leads to overlay failure and session interruption, which lead to long handover delay and intolerable service disruption time. The wireless network has more uncertain dynamics than the wired network, and the dynamics degrade the stable data rate for P2P live streaming. In order to improve the streaming continuity, we propose a cross-layer design to achieve the seamless handover and adjust the playback quality. This article discusses the architecture of present Mobile IP network, and we overcome the challenges to apply P2P service on Mobile IP. The proposed scheme maintains P2P session during IP handover and successfully reroutes packets to the new visited subnet. The motivation is the successful integration of Mobile IP and P2P live streaming, and the goal is the improvement of playback continuity. The simulation results explain that our proposed scheme indeed meliorates the performance of mobile P2P live streaming.
Investigation of the <i>Origanum onites</i> L. Essential Oil Using the Chorioallantoic Membrane (CAM) Assay (2003)

The in vivo test on the chorioallantoic membrane of the fertilized hen's egg (CAM assay) is a current method to determine antiangiogenic, antiinflammatory activity and toxic effects of individual compounds or complex plant extracts. The method is used for testing natural compounds in small amounts for revealing various modes of action and the complex mechanisms related to angiogenesis and inflammation. Furthermore, possible side effects such as membrane irritation, toxic, and anticoagulant properties of the investigated material in question can be detected. For the evaluation, the essential oil obtained by hydrodistillation of the aerial parts of Origanum onites L., a common spice and medicinal plant, was tested for its effect in the chorioallantoic membrane (CAM) assay. The essential oil composition was revealed by means of gas chromatography-mass spectrometry (GC-MS). Eighty three components were identified, representing 99.1% of the total oil. Carvacrol, thymol, p-cymene, and gamma-terpinene were found as major components and were also individually tested in the CAM assay. Along with the monoterpenes carvacrol and thymol, their methyl ether derivatives were also examined for comparison of their physiological action. Neither the essential oil nor its components showed any pronounced antiinflammatory or antiangiogenic property in the CAM assay, at 10-250 microg/pellet. However, the irritant effect of the essential oil was linked to thymol in a dose-response fashion, up to 10 microg/pellet, where it was still showing irritation.
Postnatal NMR changes in guinea pig central nervous system: Potential relevance to experimental allergic encephalomyelitis (1988)

The age of sensitization determines the clinical course of experimental allergic encephalomyelitis (EAE) in the guinea pig. Adult animals immunized with central nervous system (CNS) tissue develop acute, fulminant EAE, whereas a relapsing-remitting illness resembling multiple sclerosis occurs if sensitization occurs in the first 2 weeks of life. This study characterized the changes in the proton nuclear magnetic resonance (NMR) relaxometry and imaging of the CNS during the immediate postnatal period. T1 and T2 relaxation times in cerebral hemispheres and spinal cords of strain 13 guinea pigs were consistently prolonged at birth, progressively shortened in the first few weeks of life, and achieved adult levels by age 6 to 11 weeks. There were no age-dependent differences in T1 and T2 relaxation times and tissue specific gravity in either strain 13 or Hartley guinea pigs following immunization with complete Freund's adjuvant, an agent previously reported to disrupt the blood-brain barrier to IgG and albumin in strain 13 guinea pigs. The CNS of neonatal guinea pigs appeared well myelinated by light microscopy and there was no apparent difference in the extent of myelination between newborn and adult animals. Although it was possible to distinguish gray from white matter in the cervical spinal cord of newborn guinea pigs by magnetic resonance imaging (MRI) techniques, gray/white contrast was less satisfactory in the cerebral hemispheres until approximately 6 weeks of life when it was possible to differentiate gray matter, white matter, and cerebrospinal fluid. This study indicates that NMR relaxation times change during early postnatal life, at a time corresponding to the unexplained differences in susceptibility to an immune challenge. These developmental changes appear to be independent of the degree of CNS myelination.
Intrinsic kinetic equation for oxygenreduction reaction in acidic media: the double Tafel slope and fuelcell applications (2008)

According to Sergio Trasatti, "A true theory of electrocatalysis will not be available until activity can be calculated a priori from some known properties of the materials." Toward this goal, we developed intrinsic kinetic equations for the hydrogen oxidation reaction (HOR) and the oxygen reduction reaction (ORR) using as the kinetic parameters the free energies of adsorption and activation for elementary reactions. Rigorous derivation retained the intrinsic connection between the intermediates' adsorption isotherms and the kinetic equations, affording us an integrated approach for establishing the reaction mechanisms based upon various experimental and theoretical results. Using experimentally deduced free energy diagrams and activity-and-barriers plot for the ORR on Pt(111), we explained why the Tafel slope in the large overpotential region is double that in the small overpotential region. For carbon-supported Pt nanoparticles (Pt/C), the polarization curves measured with thin-film rotating disk electrodes also exhibit the double Tafel slope, albeit Pt(111) is several times more active than the Pt nanoparticles when the current is normalized by real surface area. An analytic method was presented for the polarization curves measured with H2 in proton exchange membrane fuel cells (PEMFCs). The fit to a typical iR-free polarization curve at 80 degrees C revealed that the change of the Tafel slope occurs at about 0.77 V that is the reversible potential for the transition between adsorbed O and OH on Pt/C. This is significant because it predicts that the Butler-Volmer equation can only fit the data above this potential, regardless the current density. We also predicted a decrease of the Tafel slope from 70 to 65 mV dec(-1) at 80 degrees C with increasing oxygen partial pressure, which is consistent with the observation reported in literature.
Inadequate lung development and bronchial hyperplasia in mice with a targeted deletion in the <i>Dutt1</i> / <i>Robo1</i> gene (2001)

Chromosome 3 allele loss in preinvasive bronchial abnormalities and carcinogen-exposed, histologically normal bronchial epithelium indicates that it is an early, possibly the first, somatic genetic change in lung tumor development. Candidate tumor suppressor genes have been isolated from within distinct 3p regions implicated by heterozygous and homozygous allele loss. We have proposed that DUTT1, nested within homozygously deleted regions at 3p12-13, is the tumor suppressor gene that deletion-mapping and tumor suppression assays indicate is located in proximal 3p. The same gene, ROBO1 (accession number ), was independently isolated as the human homologue of the Drosophila gene, Roundabout. The gene, coding for a receptor with a domain structure of the neural-cell adhesion molecule family, is widely expressed and has been implicated in the guidance and migration of axons, myoblasts, and leukocytes in vertebrates. A deleted form of the gene, which mimics a naturally occurring, tumor-associated human homozygous deletion of exon 2 of DUTT1/ROBO1, was introduced into the mouse germ line. Mice homozygous for this targeted mutation, which eliminates the first Ig domain of Dutt1/Robo1, frequently die at birth of respiratory failure because of delayed lung maturation. Lungs from these mice have reduced air spaces and increased mesenchyme, features that are present some days before birth. Survivors acquire extensive bronchial epithelial abnormalities including hyperplasia, providing evidence of a functional relationship between a 3p gene and the development of bronchial abnormalities associated with early lung cancer.
Transcranial Magnetic Stimulation in the Treatment of Depression<subtitle>A Double-blind, Placebo-Controlled Trial</subtitle> (2003)

<h3>Background</h3> High-frequency left-sided repetitive transcranial magnetic stimulation (HFL-TMS) has been shown to have antidepressant effects in double-blind trials. Low-frequency stimulation to the right prefrontal cortex (LFR-TMS) has also shown promise, although it has not been assessed in treatment-resistant depression and its effects have not been compared with those of HFL-TMS. <h3>Objective</h3> To prospectively evaluate the efficacy of HFL-TMS and LFR-TMS in treatment-resistant depression and compared with a sham-treated control group. <h3>Design</h3> A double-blind, randomized, sham-controlled trial. <h3>Setting</h3> Two general psychiatric services. <h3>Participants</h3> Sixty patients with treatment-resistant depression who had failed to respond to therapy with multiple antidepressant medications were divided into 3 groups of 20 that did not differ in age, sex, or any clinical variables. All patients completed the double-blind phase of the study. <h3>Interventions</h3> Twenty 5-second HFL-TMS trains at 10 Hz and five 60-second LFR-TMS trains at 1 Hz were applied daily. Sham stimulation was applied with the coil angled at 45° from the scalp, resting on the side of one wing of the coil. <h3>Main Outcome Measure</h3> Score on the Montgomery-Åsberg Depression Rating Scale. <h3>Results</h3> There was a significant difference in response among the 3 groups (F<sub>56,2</sub>= 6.2), with a significant difference between the HFL-TMS and sham groups and between the LFR-TMS and sham groups (<i>P</i><.005 for all) but not between the 2 treatment groups. Baseline psychomotor agitation predicted successful response to treatment. <h3>Conclusions</h3> Both HFL-TMS and LFR-TMS have treatment efficacy in patients with medication-resistant major depression. Treatment for at least 4 weeks is necessary for clinically meaningful benefits to be achieved. Treatment with LFR-TMS may prove to be an appropriate initial repetitive TMS strategy in depression taking into account safety, tolerability, and efficacy considerations.
Parallel Acquisition of Two-Dimensional NMR Spectra of Several Nuclear Species (2006)

We show that two or more two-dimensional NMR correlation spectra can be recorded in a single shot, using a multicoil radio-frequency probe and receiver system designed for simultaneous parallel acquisition of signals from different nuclear species such as 1H, 13C, and 15N. Dubbed PANSY (parallel acquisition NMR spectroscopy), this new technique shows promise for recording several multidimensional NMR spectra of different nuclear species in a very short time.
