Does where you live matter? Leisure-time physical activity among Canadian youth: a multiple cross-sectional study (2016)

Leisure-time physical activity was associated with environmental factors at multiple geographic scales among Canadian youth. The variation was more important at the neighbourhood level. The results provide rationale for further investigation into how leisure-time physical activity is promoted in different contexts.
Android permissions (2012)

Android's permission system is intended to inform users about the risks of installing applications. When a user installs an application, he or she has the opportunity to review the application's permission requests and cancel the installation if the permissions are excessive or objectionable. We examine whether the Android permission system is effective at warning users. In particular, we evaluate whether Android users pay attention to, understand, and act on permission information during installation. We performed two usability studies: an Internet survey of 308 Android users, and a laboratory study wherein we interviewed and observed 25 Android users. Study participants displayed low attention and comprehension rates: both the Internet survey and laboratory study found that 17% of participants paid attention to permissions during installation, and only 3% of Internet survey respondents could correctly answer all three permission comprehension questions. This indicates that current Android permission warnings do not help most users make correct security decisions. However, a notable minority of users demonstrated both awareness of permission warnings and reasonable rates of comprehension. We present recommendations for improving user attention and comprehension, as well as identify open challenges.
Individual and Combined Effect of Silicon and Calcium Ions on Osteoblast Gene Expression and Matrix Formation (2012)

This study tests the hypothesis that silicon and calcium ions combinatorially target gene expression during osteoblast differentiation. MC3T3‐E1 subclone 4 osteoblast progenitors were exposed to elevated Si 4+ (Na 2 SiO 3 ) and Ca 2+ (CaCl 2 ) ion treatments both individually (50 ppm) and combinatorially (50 ppm Si + 50 ppm Ca) above control media conditions (α‐MEM, 10% FBS, 1% pen‐strep). Cell density significantly increased with time (5 days), but no significant difference was observed between treatments. All treatments were additionally supplemented with ascorbic acid (AA, 50 ppm) to induce differentiation. Relative expression of collagen type 1 (Col1α1, day 1), core‐binding factor a (cbfa1 or Runx2, day 6), and osteocalcin (OCN, day 6) was studied based on the timeline of osteoblast differentiation. Increased Si or Ca ion treatments enhanced Col1α1, Runx2, and OCN expression. Increased Si + Ca ion treatments enhanced OCN expression alone with no affect on Col1α1 and suppression of Runx2 (no amplification). Collagen fiber bundles were dense and elongated, for extracellular matrices (ECM) exposed to Si ions as compared to other treatments. These results indicated that individual ions enhanced multiple osteogenic gene expression while combined ion treatments enhanced individual gene expression.

T-cassette ligation: a method for direct sequencing and cloning of PCR-amplified DNA fragments. (1994)

We describe a method to ligate a PCR-amplified DNA fragment with T-protruding cassettes, which have multiple sites for endonuclease, promoter sequences of T3 and T7, and annealing sites for the universal M13 forward and reverse primers. This method, which we named T-cassette ligation, substantially facilitated direct sequencing and subcloning of PCR products. Two T-cassettes with a protruding T at their 3' ends were obtained by annealing adaptor oligomers to XbaI- or XhoI-digested pBluescript. A DNA fragment amplified by the first PCR was ligated separately to one of the two T-cassettes. The second PCR was performed using a primer complementary to one of the two T-cassettes and one of the two primers used for the first PCR to amplify the ligation product in low abundance. The resultant two DNA fragments had the T3 and T7 promoter, and an annealing site for the universal M13 forward and reverse primer, respectively. These DNA fragments were applicable to direct sequencing. For the purpose of subcloning, the third PCR was carried out with two primers each complementary to each of two T-cassettes and two PCR-amplified DNAs by the second PCR, as templates. The PCR product of the third PCR had multiple sites of the pBluescript polycloning site at both ends, facilitating its subcloning into pBluescript.
Coherent optical spectroscopy of a hybrid nanocrystal complex embedded in a nanomechanical resonator (2010)

We have theoretically investigated a hybrid nanocrystal complex consisted of a metal nanoparticle (MNP) and a semiconductor quantum dot (SQD) embedded in a nanomechanical resonator in the simultaneous presence of a strong control field and a weak probe field. It is shown that the resonance amplification peak of the probe spectrum will enhance dramatically due to the coupling of the plasmon, exciton and nanomechanical resonator. The enhancement increases significantly with decreasing the distance between the metal nanoparticle and a quantum dot, which implies the strong plasmon enhancement effect in this coupled system. The results obtained here may have the potential applications such as tunable Raman lasers and bio-sensors.

Visual decision-support tools for first responders (2004)

In an age of heightened awareness due to terrorist threats, there is a great need for decision-support tools for first responder teams, such as FBI bomb squads, HAZMAT teams, etc. These teams suffer from the following deficiencies: "lack of information regarding hazards and equipment, and inadequate management and communication of information" (Jackson et al. 2002, 37). Decision-support tools strengthen the communication and management of disaster situations, and subsequently protect the safety and security of first responders and citizens. This project was the design and implementation of visual tools that improve CoBRA/spl reg/ (chemical biological response aide), a portable decision- support system that facilitates first responders in hazardous material accidents and attacks (DGI, "CoBRA/spl reg/," 2003). Testing of these tools clearly demonstrates the improvements that result from their integration: the automated briefing tool reduces data transfer time by 33%, while it increases reliability of information and the speed of communication within first responder teams. The ATP 45 interface decreases the time required for graphing of isolation and downwind protection zones by 80%. The sketchpad tool reduces the time required for mapping by 83.3%; finally, the GPS tool decreases the time required to understand global positional awareness by 95%. In every case, these tools strengthen the quality and accuracy of information available to first responders; thus, they meet the needs of these teams in handling disaster situations.
Some Observations on the Cured Shape of Thin Unsymmetric Laminates (1981)

This paper discusses the fact that the cured shape of thin unsymmetric laminates do not conform to the predictions of classical lamination theory. Rather than being saddle shaped, as predicted by the classical theory, the paper shows that thin unsymmetric laminates cure into a shape of a right circular cylinder. This anomalous behavior has been observed by many but the paper serves to quantify the effect and to inspire investigators to begin thinking about using the phenomenon to advantage. The paper indicates that the anomalous behavior is repeatable and that thicker laminates con form to the predictions of the classical theory. Laminates of the [0/90 2 /θ ] T , [0 2 /θ 2 ] T and [0 4 /θ 4 ] T families are investigated for this be havior and it is shown the principal curvature directions of the cylindrical shapes are predictable.
Synthesizing Biofunctionalized Nanoparticles to Image Cell Signaling Pathways (2006)

This minireview outlines the synthetic efforts, from our research group, to produce nanomaterials for use as imaging agents to study cell signaling pathways. An overview of our approach to the synthesis and biofunctionalization of metal, semiconductor, and ceramic nanomaterials is presented. The probes investigated include coinage metals, Cd-based, Ge(o), naturally occurring fluorescent (NOF) minerals, and Ln-based nanoparticles which were synthesized from novel metal alkoxide, amide, and alkyl precursors. We illustrate the applications of some of these materials as imaging probes to detect signaling pathway components and cellular responses to signals (apoptosis and degranulation) in inflammatory and cancer cells.
SPEC CPU2000: measuring CPU performance in the New Millennium (2000)

As computers and software have become more powerful, it seems almost human nature to want the biggest and fastest toy you can afford. But how do you know if your toy is tops? Even if your application never does any I/O, it's not just the speed of the CPU that dictates performance. Cache, main memory, and compilers also play a role. Software applications also have differing performance requirements. So whom do you trust to provide this information? The Standard Performance Evaluation Corporation (SPEC) is a nonprofit consortium whose members include hardware vendors, software vendors, universities, customers, and consultants. SPEC's mission is to develop technically credible and objective component- and system-level benchmarks for multiple operating systems and environments, including high-performance numeric computing, Web servers, and graphical subsystems. On 30 June 2000, SPEC retired the CPU95 benchmark suite. Its replacement is CPU2000, a new CPU benchmark suite with 19 applications that have never before been in a SPEC CPU suite. The article discusses how SPEC developed this benchmark suite and what the benchmarks do.
Local and systemic delivery of low molecular weight heparin following PTCA: Acute results and 6‐month follow‐up of the initial clinical experience with the porous balloon (PILOT‐study) (1998)

The purpose of this study was to assess safety and feasibility of intracoronary delivery of reviparin using a porous balloon following percutaneous transluminal coronary angioplasty. The 2.7 mm porous balloon used in this study had 35 holes arranged in a spiral pattern. Eighteen patients (male n = 10, female n = 8, age 63 ± 9 years) undergoing successful PTCA in coronary arteries with a vessel diameter of 2.5 to 3.0 mm determined by online QCA (LAD = 11, RCX = 3, RCA = 4) were included. They received a bolus of 7,000 anti-Xa-IU reviparin followed by local delivery of 1,500 anti-Xa-IU in 4 ml with an injection pressure of 2 atm. The patients received additionally 10500 anti-Xa-units intravenously during the following 24 hours and a daily dose of 7000 anti-Xa-units reviparin subcutaneously for the following 28 days. Angiograms were obtained before and after PTCA, directly after local delivery, at 24 hours postintervention and after 6 months. The primary success rate was 100%. Quantitative coronary angiography showed a minimum luminal diameter of 0.42 ± 0.14 mm before PTCA, 1.87 ± 0.45 after PTCA, 1.67 ± 0.43 after LDD, 1.63 ± 0.46 after 24 hours, and 1.06 ± 0.6 after 6 months. Angiographic follow-up was obtained in all patients. No major complications occurred during the 6-month follow-up period. The angiographic restenosis rate was 28% (5/18) at follow-up. This study demonstrates safety and feasibility of local intracoronary delivery of reviparin with a porous balloon following PTCA even in smaller diameter coronary arteries. Cathet. Cardiovasc.

PSIM modelling and hall sensors based adaptive control of switched reluctance motor drive for EV applications (2017)

SRM is widely used in Electric vehicle applications due to its high starting torque, wide range of variable speed operation and independent phase control. For the work in this paper, we have extended the models in Powersim (PSIM) to include 12/8 Switched Reluctance Motor (SRM) and its drive and have implemented the control parameters with focus on energy efficiency, drive complexity and control characteristics. For enhanced-energy efficiency, regenerative braking is used to recover energy during de-energizing and braking. The hardware implementation has been carried out on a SRM with sensing permanent magnets over the rotor poles for enhanced position accuracy and the drive control has been established on mini6410 using kernel level programming with input from three Hall sensors for complementary positioning and control of phase currents, as shown in block diagram in figure 1. The controller output is used to drive an asymmetric converter to actuate the propulsion operation. Further, the speed tracking and control is done using discrete time PI controller. Our results indicate an efficiency of 88.03 % with rise time of 7 sec for 3000 rpm (3200 rpm rated) with steady state error of 0.22%. The drive has been incorporated for EV application in a purpose built structure for the Shell Eco-Marathon-Asia Challenge, 2017 to validate the performance of our drive design.
Generation of neutrons as a result of explosive initiation of the DD reactions in conical targets (1980)

A neutron yield of approximately 10/sup 6/ neutrons was recorded as a result of deceleration in deuterium-filled conical targets of metallic liners accelerated by detonation of solid explosives. Theoretical calculations of the neutron-generation process were performed, taking into account the cone deformation in the final stage of compression and heating of deuterium.
Learning Social Relation Traits from Face Images (2015)

Social relation defines the association, e.g, warm, friendliness, and dominance, between two or more people. Motivated by psychological studies, we investigate if such fine-grained and high-level relation traits can be characterised and quantified from face images in the wild. To address this challenging problem we propose a deep model that learns a rich face representation to capture gender, expression, head pose, and age-related attributes, and then performs pairwise-face reasoning for relation prediction. To learn from heterogeneous attribute sources, we formulate a new network architecture with a bridging layer to leverage the inherent correspondences among these datasets. It can also cope with missing target attribute labels. Extensive experiments show that our approach is effective for fine-grained social relation learning in images and videos.

Plant defences against ants provide a pathway to social parasitism in butterflies (2015)

Understanding the chemical cues and gene expressions that mediate herbivore-host-plant and parasite-host interactions can elucidate the ecological costs and benefits accruing to different partners in tight-knit community modules, and may reveal unexpected complexities. We investigated the exploitation of sequential hosts by the phytophagous-predaceous butterfly Maculinea arion, whose larvae initially feed on Origanum vulgare flowerheads before switching to parasitize Myrmica ant colonies for their main period of growth. Gravid female butterflies were attracted to Origanum plants that emitted high levels of the monoterpenoid volatile carvacrol, a condition that occurred when ants disturbed their roots: we also found that Origanum expressed four genes involved in monoterpene formation when ants were present, accompanied by a significant induction of jasmonates. When exposed to carvacrol, Myrmica workers upregulated five genes whose products bind and detoxify this biocide, and their colonies were more tolerant of it than other common ant genera, consistent with an observed ability to occupy the competitor-free spaces surrounding Origanum. A cost is potential colony destruction by Ma. arion, which in turn may benefit infested Origanum plants by relieving their roots of further damage. Our results suggest a new pathway, whereby social parasites can detect successive resources by employing plant volatiles to simultaneously select their initial plant food and a suitable sequential host.

Chemical Mechanical Planarization of Ruthenium with Oxone as Oxidizer (2011)

Potassium peroxymonosulfate (Oxone) was investigated as an oxidizing agent in silica based slurries for chemical mechanical planarization of Ru. Upon addition of oxone, the Ru removal rate increases significantly in the pH range of 1–6. The slurry stability is poor at pH 3 and higher. At pH 2, oxone enhances the Ru removal rate even in the absence of abrasive, indicating that a soft film is formed on the Ru surface. Ru dissolution experiments show that the static etch rate is low. The Ru removal rate variation with pressure and velocity does not follow the Preston equation.
Enhancement of Cytotoxicity by the Combination of Anticancer Drugs in Human Lung Adenocarcinoma Cell Line (PC-14) (1997)

Background No ideal combination chemotherapy for lung cancer has been established even though lots of combination anticancer chemotherapies have been tried. For the combination of anticancer drugs, the interaction of anticancer drugs is very important but unpredictable factor. In this experiments we designed and tested new experiment to measure the interaction of two anticancer drugs using MTT assay in an attempt to predict clinical response of the combination regimen. Methods With human lung adenocarcinoma cell line (PC-14), the cytotoxic effect of cisplatin adriamycin mitomycin C and etoposide were measured by in Vitro chemosensitivity test (MTT assay). The combined cytotexic effects of combination of two drugs were also measured in every combination of the drug concentrations and analyzed the interaction by Anova analysis of two way factorial design. Results Four individual drugs showed cytotoxic effects on PC-14 by dose dependent fashion Comparison of two drug combinations revealed that mitomycin C + cisplatin and adriamycin + cisplatin combinations showed stronger synergistic cytotoxic effects. Conclusion From this experiments we suggest two combinations of mitomycin C + cisplatin and adriamycin + cisplatin as chemotherapeutic regimens for unresectable non-small cell lung cancer. Furthermore, this experimental deign could be applied b other types of cancer requiring combination anticancer chemotherapy.
Immunolocalization and expression of kinin B1R and B2R receptors in human inflammatory bowel disease (2005)

Bradykinin is a mediator of inflammation, responsible for pain, vasodilation, and capillary permeability. Bradykinin receptor 1 (B(1)R) and bradykinin receptor 2 (B(2)R) are G protein-coupled receptors that mediate kinin effects. The latter is constitutive and rapidly desensitized; the former is induced by inflammatory cytokines and resistant to densensitization. The distribution of bradykinin receptors in human intestinal tissue was studied in patients with inflammatory bowel disease (IBD), namely ulcerative colitis (UC) and Crohn's disease (CD). Both B(2)R and B(1)R proteins are expressed in the epithelial cells of normal and IBD intestines. B(1)R protein is visualized in macrophages at the center of granulomas in CD. B(2)R protein is normally present in the apexes of enterocytes in the basal area and intracellularly in inflammatory tissue. In contrast, B(1)R protein is found in the basal area of enterocytes in normal intestine but in the apical portion of enterocytes in inflamed tissue. B(1)R protein is significantly increased in both active UC and CD intestines compared with controls. In patients with active UC, B(1)R mRNA is significantly higher than B(2)R mRNA. However, in inactive UC patients, the B(1)R and B(2)R mRNA did not differ significantly. Thus bradykinin receptors in IBD may reflect intestinal inflammation. Increased B(1)R gene and protein expression in active IBD provides a structural basis of the important role of bradykinin in chronic inflammation.
