Second Generation Swimming Feedback Device Using a Wearable Data Processing System based on Underwater Visible Light Communication (2013)

Swimmers performance evaluation is important for the swimmers, their coaches and trainers. Most systems depend on visual, video processing or sensors and require post processing to obtain the swim data. Stroke rate, stroke length and swim velocity data are useful parameters for a swimmer during a swim. Swimmers can then adjust their swim to achieve optimal performance. A wearable data processing system was designed, implemented and tested using visible light communication. A wrist-mounted accelerometer with a communications link to a receiver located on the goggles allows visual information to be given to the athlete. This helps swimmers to swim with consistent pace based on a multi-coloured display. The data processing system was based on a circular buffer to read real time acceleration data. The maximum acceleration and the position of the maximum acceleration during one stroke are determined in firmware. The time difference between strokes is transmitted to the goggles. An algorithm at the receiver uses the data to switch on the LED colour so that the swimmer reacts according to previous instructions. The second generation system (size 35 x 35 mm, cost $19.89AU) was designed and implemented. The system was tested with different swim speeds (slow and fast) and different strokes (free style, back stroke, breast stroke and butterfly) to validate the system. These experiments were used to optimise the system and verify that the complete system is viable under different conditions, styles and swimmers.
Measurement of the top quark pair production cross section inpp¯collisions using multijet final states (1999)

We have studied $t\overline{t}$ production using multijet final states in $p\overline{p}$ collisions at a center-of-mass energy of 1.8 TeV, with an integrated luminosity of 110.3 ${\mathrm{pb}}^{\ensuremath{-}1}.$ Each of the top quarks with these final states decays exclusively to a bottom quark and a W boson, with the W bosons decaying into quark-antiquark pairs. The analysis has been optimized using neural networks to achieve the smallest expected fractional uncertainty on the $t\overline{t}$ production cross section, and yields a cross section of 7.1$\ifmmode\pm\else\textpm\fi{}$2.8 (stat)$\ifmmode\pm\else\textpm\fi{}$1.5 (syst) pb, assuming a top quark mass of 172.1 GeV/${c}^{2}.$ Combining this result with previous D\O{} measurements, where one or both of the W bosons decay leptonically, gives a $t\overline{t}$ production cross section of $5.9\ifmmode\pm\else\textpm\fi{}1.2 (\mathrm{stat})\ifmmode\pm\else\textpm\fi{}1.1 (\mathrm{syst})\mathrm{}\mathrm{pb}.$
Fluorescent nucleic acid base analogues (2010)

The use of fluorescent nucleic acid base analogues is becoming increasingly important in the fields of biology, biochemistry and biophysical chemistry as well as in the field of DNA nanotechnology. The advantage of being able to incorporate a fluorescent probe molecule close to the site of examination in the nucleic acid-containing system of interest with merely a minimal perturbation to the natural structure makes fluorescent base analogues highly attractive. In recent years, there has been a growing interest in developing novel candidates in this group of fluorophores for utilization in various investigations. This review describes the different classes of fluorophores that can be used for studying nucleic acid-containing systems, with an emphasis on choosing the right kind of probe for the system under investigation. It describes the characteristics of the large group of base analogues that has an emission that is sensitive to the surrounding microenvironment and gives examples of investigations in which this group of molecules has been used so far. Furthermore, the characterization and use of fluorescent base analogues that are virtually insensitive to changes in their microenvironment are described in detail. This group of base analogues can be used in several fluorescence investigations of nucleic acids, especially in fluorescence anisotropy and fluorescence resonance energy transfer (FRET) measurements. Finally, the development and characterization of the first nucleic base analogue FRET pair, tC(O)-tC(nitro), and its possible future uses are discussed.

Predicting the Spatio-Temporal Evolution of Chronic Diseases in Population with Human Mobility Data (2018)

Chronic diseases like cancer and diabetes are major threats to human life. Understanding the distribution and progression of chronic diseases of a population is important in assisting the allocation of medical resources as well as the design of policies in preemptive healthcare. Traditional methods to obtain large scale indicators on population health, e.g., surveys and statistical analysis, can be costly and time-consuming and often lead to a coarse spatio-temporal picture. In this paper, we leverage a dataset describing the human mobility patterns of citizens in a large metropolitan area. By viewing local human lifestyles we predict the evolution rate of several chronic diseases at the level of a city neighborhood. We apply the combination of a collaborative topic modeling (CTM) and a Gaussian mixture method (GMM) to tackle the data sparsity challenge and achieve robust predictions on health conditions simultaneously. Our method enables the analysis and prediction of disease rate evolution at fine spatio-temporal scales and demonstrates the potential of incorporating datasets from mobile web sources to improve population health monitoring. Evaluations using real-world check-in and chronic disease morbidity datasets in the city of London show that the proposed CTM+GMM model outperforms various baseline methods.
Activation of Rac by Asef2 promotes myosin II-dependent contractility to inhibit cell migration on type I collagen (2013)

Non-muscle myosin II (MyoII) contractility is central to the regulation of numerous cellular processes, including migration. Rho is a well-characterized modulator of actomyosin contractility, but the function of other GTPases, such as Rac, in regulating contractility is currently not well understood. Here, we show that activation of Rac by the guanine nucleotide exchange factor Asef2 (also known as SPATA13) impairs migration on type I collagen through a MyoII-dependent mechanism that enhances contractility. Knockdown of endogenous Rac or treatment of cells with a Rac-specific inhibitor decreases the amount of active MyoII, as determined by serine 19 (S19) phosphorylation, and negates the Asef2-promoted increase in contractility. Moreover, treatment of cells with blebbistatin, which inhibits MyoII activity, abolishes the Asef2-mediated effect on migration. In addition, Asef2 slows the turnover of adhesions in protrusive regions of cells by promoting large mature adhesions, which has been linked to actomyosin contractility, with increased amounts of active β1 integrin. Hence, our data reveal a new role for Rac activation, promoted by Asef2, in modulating actomyosin contractility, which is important for regulating cell migration and adhesion dynamics.
Introduction (2010)

A close&nbsp;examination&nbsp;of the role of intelligence in shaping America’s perception of the Vietnam&nbsp;War, looking closely at the intelligence leadership and decision process. In 1967, intelligence was called upon to bolster support for the Vietnam War and allowed America’s leaders to portray a ‘bankrupt’ enemy ready to quit the battlefield. The audacious Tet Offensive of 1968 shattered this image and although it ended with an American military victory, it is remembered as the juncture when American support turned against the war. Public opinion on the war was a primary concern for the Johnson Administration, and US intelligence played a decisive role in providing an overly optimistic view of the enemy’s demise. As the "bankrupt" enemy attacked with a ferocity and intensity that shocked the American public, intelligence had set-up the American public for a fall. How, Americans wanted to know, could an enemy whose numbers had been so decimated now launch such an all-out offensive? From this examination and an understanding of how the enemy viewed itself, the conclusion is made that four severe breaches of intelligence etiquette occurred during the period leading up to Tet. This phenomenon is the ‘Tet effect’ – the loss of credibility when leaders portray a situation based upon intelligence that is shown to be disingenuous. This book will be of great interest to students of the Vietnam war, intelligence and strategic studies in general.
Holographic Recording of Vertical Surfaces (2011)

A simple method is presented for recording vertical surfaces along with horizontal surfaces in a standard DHM set-up. The purpose is to avoid rotating the sample, which would require new alignment and calibration procedures. The main targeted application is the recording of the top surface and vertical sides of a silicon chip in a single process.
A comparison of endotracheal tube cuff pressures using estimation techniques and direct intracuff measurement. (2003)

Cuffed endotracheal tubes are one aspect of airway management designed to ensure safety, yet patients can be at risk for injury from underinflated and overinflated endotracheal cuffs. Tracheal pressures exceeding approximately 48 cm H2O impede capillary blood flow, potentially causing tracheal damage, and pressures below approximately 18 mm Hg may increase the risk of aspiration. There is no standard identified in the literature describing the method of cuff inflation, and nurse anesthetists use various cuff inflation techniques. The purpose of this study was to compare endotracheal cuff pressures obtained by estimation techniques with direct endotracheal cuff pressure measurements. A convenience sample of 40 anesthesia providers (nurse anesthesia students, Certified Registered Nurse Anesthetists, and anesthesiologists) inflated the endotracheal tube cuff using their usual inflation technique. The endotracheal tube cuff pressure was measured with a noninvasive manometer connected to the pilot balloon. Pressures obtained by estimation techniques ranged from 6 to 60 cm H2O (mean = 44.5; SD = 13.07). Analysis revealed that fewer than one third of the anesthesia providers inflated the cuff within an ideal range. No differences were found between level of anesthesia provider and cuff inflation pressures. We conclude that estimation techniques for cuff inflation are inadequate and suggest that direct measurements be used.

Inhibition of sodium-calcium exchange in cardiac sarcolemmal membrane vesicles. 2. Mechanism of inhibition by bepridil (1988)

Bepridil, an antiarrhythmic agent, inhibits Na-Ca exchange in cardiac sarcolemmal membrane vesicles (Ki = 30 microM) by a novel mechanism, different from that determined for amiloride analogues [Slaughter, R. S., Garcia, M. L., Cragoe, E. J., Jr., Reeves, J. P., & Karczorowski, G. J. (1988) Biochemistry (preceding paper in this issue)]. Bepridil causes partial inhibition of Nai-dependent Ca2+ uptake but complete block of Nao-dependent Ca2+ efflux. Inhibition of Na-Ca exchange is noncompetitive vs Ca2+ but competitive vs Na+ in both K+ and sucrose. Bepridil also blocks Ca-Ca exchange, with or without K+ present. However, K+ has two effects on inhibition: it reduces the potency of bepridil and causes inhibition to become partial. Inhibition of Ca-Ca exchange displays noncompetitive kinetics vs Ca2+ in either sucrose or K+. Dixon analyses of Na-Ca exchange inhibition caused by mixtures of bepridil and amiloride analogues demonstrate that these compounds produce a competitive interaction at a common carrier site that is evident only at low concentrations of amiloride inhibitors. Hill plots of bepridil inhibition of Na-Ca and Ca-Ca exchange display unitary Hill coefficients. These results indicate that bepridil interacts at only one substrate-binding site, the site selective for Na+, where amiloride analogues also preferentially interact. However, unlike amiloride, bepridil does not interact at the common Na+, Ca2+-binding site of the carrier.(ABSTRACT TRUNCATED AT 250 WORDS)
Simplified Thermal Modeling for IGBT Modules With Periodic Power Loss Profiles in Modular Multilevel Converters (2018)

One of the future challenges in modular multilevel converters (MMCs) is how to size key components with compromised costs and design margins, while fulfilling specific reliability targets. It demands better thermal modeling compared to the state-of-the-arts in terms of both accuracy and simplicity. Different from two-level power converters, MMCs have inherent dc-bias in arm currents and the power device conduction time is affected by operational parameters. A time-wise thermal modeling for the power devices in MMCs is, therefore, an iteration process and time-consuming. This paper, thus, proposes a simple analytical thermal modeling method, which adopts equivalent periodic power loss profiles. More importantly, time-domain simulations are not required in the proposed method. Benchmarking of the proposed methods with the prior-art solutions is performed in terms of parameter sensitivity and model accuracy with a case study on a 30-MW MMC system. Experiments are carried out on a specifically designed scaled-down system to verify the electrothermal aspects.

The Effect of Daughters on Partisanship (2010)

finds that, controlling for total number of children, each additional daughter makes a member of Congress more likely to vote liberally and attributes this finding to socialization. However, daughters' influence could manifest differently for elite politicians and the general citizenry, thanks to the selection gradient particular to the political process. This study asks whether the proportion of female biological offspring affects political party identification. Using nationally-representative data from the General Social Survey, we find that female offspring induce more conservative political identification. We hypothesize that this results from the change in reproductive fitness strategy that daughters may evince.

CRYPTATES XIX. Ligands polyaza‐polyoxa‐macrobicycliques: Synthèse et complexes métalliques (1976)

Polyaza‐polyoxa macrobicyclic ligands: its synthesis and metal complexes. The synthesis of the polyaza‐polyoxa macrobicyclic ligands 1–4 is described. They form complexes with a variety of metal cations, transition metal cations as well as alkali and alkaline‐earth cations. These complexes may be formulated as cation inclusion complexes, cryptates , in which the cation is contained in the intramolecular cavity. The properties of the complexes are described. An especially interesting feature is that these ligands, polymines of macrobicyclic topology, provide a means of trapping transition metal cations inside a molecular cavity; thus they impose coordination geometries and may modify the spectral and redox properties of the cations.

Trajectory generation for myoelectrically controlled lower limb active knee exoskeleton (2014)

Aim of this paper is to generate joint angle trajectory of knee joint and fed it to a myoelectric controlled lower body exoskeleton to regenerate lost gait pattern. EMG signal of six different lower limb muscles has been acquired and fused using standard fusion technique discarding spurious data. From the fused EMG data, different gait parameters like stride time, gait phase etc has been calculated. Joint trajectory during a gait cycle is obtained from Kinect sensor that can extract comprehensive gait information from all parts of the body. Joint angle obtained from kinect is combined with the gait parameters acquired from EMG and together they will be fed to a robotic lower limb exoskeleton. As the exoskeleton joints are fed with true joint angle data of the user and the joints are driven by users own intention signal, functioning, control and acceptability of the exoskeleton device is much more to a user. The system has massive application in gait rehabilitation for post stroke patients, people suffering from cerebral palsy and other neuro muscular gait defects, amputees etc.
Shear bond strength of orthodontic adhesives on different tooth types : an in vitro study (2006)

Introduction: Owing to the variety of materials and methods employed, comparison of the results and findings from bonding studies is difficult. Until recently, several types of teeth have been used in published research papers as a substrate in orthodontic bonding research including bovine incisors, fresh and rebonded human premolars. Objectives: The purpose of this study was to compare the shear bond strength of an adhesive bonded to different tooth surfaces (human premolar, bovine incisor and rebonded human premolar). Methods: Two groups of thirty premolar teeth and one group of bovine incisors had brackets attached in a standardized manner using Transbond XT (3M Unitek). The adhesive was cured using conventional halogen light and a specially designed tool to standardize the distance between the light curing tip and the adhesive. The debonding force was measured using Instron universal testing machine. ANOVA and Post Hoc Dunnett C test were performed to determine any significant difference among groups (p&lt;0.05). Results: The results of Post Hoc Dunnett C test indicated no statistical differences between the human premolar group and rebonded group. However, the differences existed in bond strength between bovine group versus human premolar group and bovine group versus human rebonded premolar group. Bovine group had the highest bond strength with mean values of 8.5 (S.D ? 4.2) MPa. Human premolar and rebonded groups had mean bond strengths of 6.1(S.D ? 4.5) and 4.9 (S.D ? 2.7) MPa, respectively. Conclusions: This study revealed that bovine teeth produced higher bond strength compared to both fresh and rebonded human premolar. Therefore, findings in any bond strength studies using bovine teeth should be interpreted with caution.
Detecting directional coupling in the human epileptic brain: Limitations and potential pitfalls (2008)

We study directional relationships---in the driver-responder sense---in networks of coupled nonlinear oscillators using a phase modeling approach. Specifically, we focus on the identification of drivers in clusters with varying levels of synchrony, mimicking dynamical interactions between the seizure generating region (epileptic focus) and other brain structures. We demonstrate numerically that such an identification is not always possible in a reliable manner. Using the same analysis techniques as in model systems, we study multichannel electroencephalographic recordings from two patients suffering from focal epilepsy. Our findings demonstrate that---depending on the degree of intracluster synchrony---certain subsystems can spuriously appear to be driving others, which should be taken into account when analyzing field data with unknown underlying dynamics.

All-fiber 600nm amplified spontaneous emission (ASE) source covering the spectral range of 2.75 µm to 3.35 µm (2020)

We prove the possibility of generating an amplified spontaneous emission (ASE) source using all fiber laser configuration that uses 1.2-meter single mode (SM) Dysprosium ions (Dy<sup>3+</sup>) doped ZBLAN fiber with core diameter and concentration of 12.5&mu;m and 2000ppm respectively as the gain medium. The ZBLAN fiber is directly fusion spliced to the output of 5-watt ytterbium (Yb) doped fiber laser with the center wavelength of 1094nm. The measured spectrum spans about 600nm starting around 2.75&mu;m to 3.35&mu;m and provides a total power of about 83mW. We demonstrate that our approach is more cost-effective and efficient than other systems previously reported and it opens new windows for wideband tunable fiber laser sources at 3&mu;m spectral region.
Correcting for physiological ripples improves epileptic focus identification and outcome prediction (2021)

Defining abnormal HFO rates by statistical comparison to rates in healthy tissue overcomes an important weakness in the clinical use of ripples. It improves focus identification and outcome prediction compared to standard HFO measures, increasing their clinical applicability.
