Adaptation of pulmonary O 2 uptake kinetics and muscle deoxygenation at the onset of heavy-intensity exercise in young and older adults

DeLorey, Darren S. , John M. Kowalchuk, and Donald H. Paterson. Adaptation of pulmonary O2 uptake kinetics and muscle deoxygenation at the onset of heavy-intensity exercise in young and older adults. J Appl Physiol 98: 1697–1704, 2005. First published January 7, 2005; doi:10.1152/japplphysiol.00607. 2004. —The purpose was to examine the adaptation of pulmonary O2 uptake (V̇O2p) and deoxygenation of the vastus lateralis muscle at the onset of heavy-intensity, constant-load cycling exercise in young (Y; 24 4 yr; mean SD; n 5) and older (O; 68 3 yr; n 6) adults. Subjects performed repeated transitions on 4 separate days from 20 W to a work rate corresponding to heavy-intensity exercise. V̇O2p was measured breath by breath. The concentration changes in oxyhemoglobin, deoxyhemoglobin (HHb), and total hemoglobin/myoglobin were determined by near-infrared spectroscopy (Hamamatsu NIRO300). V̇O2p data were filtered, interpolated to 1 s, and averaged to 5-s bins. HHb-near-infrared spectroscopy data were filtered and averaged to 5-s bins. A monoexponential model was used to fit V̇O2p [phase 2, time constant ( ) of V̇O2p] and HHb [following the time delay (TD) from exercise onset to the start of an increase in HHb] data. The V̇O2p was slower (P 0.001) in O (49 8 s) than Y (29 4 s). The HHb TD was similar in O (8 3 s) and Y (7 1 s); however, the HHb following TD was faster (P 0.05) in O (8 2 s) than Y (14 2 s). The slower V̇O2p kinetics and faster muscle deoxygenation in O compared with Y during heavy-intensity exercise imply that the kinetics of muscle perfusion are slowed relatively more than those of V̇O2p in O. This suggests that the slowed V̇O2p kinetics in O may be a consequence of a slower adaptation of local muscle blood flow relative to that in Y.
Security mechanisms and Vulnerabilities in LPWAN

The count of Internet of things (IoT) devices getting connected to internet are exponentially growing and is proposed to be 75 billion by 2025. IoT devices uses Low Power Wide Area Network (LPWAN) that are precisely build to operate at a lower cost with greater power efficiency and long range connectivity than traditional wireless networks. LPWAN are inherently prone to security threats since they are also wireless communication network. Secure communication is essential for LPWAN and most LPWAN technologies uses simple cryptography methods. Despite of this security mechanisms, LPWAN is vulnerable to wide range of attacks. In this paper Network architecture and Security mechanisms of LPWAN technologies (LoRa, Sigfox, NB-IoT and DASH7) are discussed and are compered in terms of IoT factors. As a case study, vulnerabilities of LoRa is also being analyzed.
Optimal Design and Control of a Wheel Motor for Electric Passenger Cars

An optimal design and control technology of a wheel motor is proposed for small electric passenger cars. The axial-flux sandwich-type disc motor is designed with a rotor embedded with neodymium-iron-boron (NdFeB) magnets and two plates of stators, and is directly mounted inside the wheel without mechanical transmission and differential gears. Sensitivity analyses are performed to choose critical design parameters, which are the most influential in design objectives, to maximize the driving torque, efficiency, rated speed, and to minimize the weight of motor under various constraints of size, materials, and power sources. The optimal driving current waveform is proven to be the same as the fundamental harmonic of the back electromotive force to produce maximum torque with least ripples. The finite-element refinement results in the motor prototype with a maximum torque over 38 kgmiddotm and a corresponding torque density of about 1.72 kgmiddotm/kg at the maximum allowable phase current of 50.25 A (rms). Two such rear driving wheels are able to drive a 600 kg passenger car to accelerate from 0 to 40 km/h in 5 s on a 15 degree incline. This dedicated wheel motor is applicable to pure or hybrid electric vehicles as a promising solution to the direct-driven electric vehicle
Calibration of output-match and its center frequency for an inductively degenerated low noise amplifier

This paper presents a new technique to calibrate the output match and its center frequency for an inductively degenerated CMOS low noise amplifier that operates at 2.45 GHz center frequency. This technique allows the compensation of any output match center frequency shift and corrects any change of the LNA output match quality. This technique is investigated theoretically and by simulation. The impact of these parameters tuning in the others performances of the LNA is studied.
Us Bank Capital Regulation: History and Changes Since the Financial Crisis

Following the financial crisis of 2007-08, capital requirements were revised along a number of important dimensions with the intent of shoring up the banking system and reducing the likelihood of another crisis. Changes included new measures of capital and increased minimum requirements, with special emphasis on requirements for the largest and most systemically important banks. In this article, I survey the history of bank capital requirements and review the new capital rules.
Influence of the Neuropsychological Functions in Theory of Mind in Schizophrenia: The False-Belief/Deception Paradigm

Abstract The aim of this study was to investigate the influence of neurocognition in a false-belief/deception theory of mind (ToM) task in a sample of patients with schizophrenia. In a cross-sectional study of 43 remitted patients, the implication of neurocognition in first- and second-order ToM stories was analyzed, controlling for clinical symptoms and duration of illness. None of the cognitive factors were associated with the first-order ToM stories. A logistic regression model with high specificity (96.3%) and sensitivity (75%) was obtained in the second-order ToM story “The Burglar,” the Information subtest (odds ratio [OR], 0.783; 95% confidence interval [CI], 0.62–0.99; p = 0.04) and the Block Design subtest (OR, 0.89; 95% CI, 0.79–1; p = 0.056) of the Wechsler Adult Intelligence Scale–III being the best predictive factors. Neurocognition was not related to first- or second-order ToM false-belief performance of the patients with schizophrenia. However, an influence of neuropsychological variables in the second-order ToM deception was observed. The clinical implications in the assessment of ToM are discussed.
Complete mitochondrial genome of the Red-billed Starling, Sturnus sericeus (Aves: Passeriformes): The first representative of the family Sturnidae with a single control region

The complete mitochondrial genome of Sturnus sericeus is 16,823 bp in length, and contains 13 protein-coding genes (PCGs), two rRNA genes, 22 transfer RNA (tRNA) genes and a single control region. All genes were coden on the H-strand, with the exceptions of one PCG (nad6) and eight tRNA genes (tRNA Gln , tRNA Ala , tRNA Asn , tRNA Cys , tRNA Tyr , tRNA Ser(UCN) , tRNA Pro and tRNA Glu ), as found in other vertebrates. All of PCGs are initiated with ATG, except for cox1, which is initiated with GTG, while stopped by five types of stop codons. All tRNA genes have the potential to fold into typical clover-leaf structure. Conserved sequences in three domains were observed in the single control region.
Degrees of freedom in interspecific allometry: an adjustment for the effects of phylogenetic constraint.

The data used in studies of bivariate interspecific allometry usually violate the assumption of statistical independence. Although the traits of each species are commonly treated as independent, the expression of a trait among species within a genus may covary because of shared common ancestry. The same effect exists for genera within a family and so on up the phylogenetic hierarchy. Determining sample size by counting data points overestimates the effective sample size, which then leads to overestimating the degrees of freedom that should be used in calculating probabilities and confidence intervals. This results in an inflated Type 1 error rate. Although some workers (e.g., Felsenstein [1985] Am. Nat. 125:1-15) have suggested that this issue may invalidate interspecific allometry as a comparative method, a correction for the problem can be approximated with variance components from a nested analysis of variance. Variance components partition the total variation in the data set among the levels of the nested hierarchy. If the variance component for each nested level is weighted by the number of groups at that level, the sum of these values is an estimate of an effective sample size for the data set which reflects the effects of phylogenetic constraint. Analysis of two data sets, using taxonomy to define levels of the nested hierarchy, suggests that it has been common for published studies of interspecific allometry to severely overestimate the number of degrees of freedom. Interspecific allometry remains an important comparative method for evaluating questions concerning individual species that are not similarly addressed by the format of most of the newer comparative methods. With the correction proposed here for estimating degrees of freedom, the major statistical weakness of the procedure is substantially reduced.
Cascade de CRFs et SVM pour la détection de références bibliographiques diffuses dans les articles scientifiques

In the context of a library of scientific articles, bibliographic references are a major source of links. Among them, some are explicit references as we can find at the end of articles or books. While others are scattered according to an implicit degree more or less strong in the text. We propose to focus on the detection of this type of references that we call diffuse in scientific articles from the field of Humanities and Social Sciences. To overcome the difficulties inherent in the detection of such references, we present a method which comprises, firstly, to identify paragraphs that contain references via a classification process and, secondly, in applying CCRFs to more accurately detect the bibliographic entries and annotate their contents.

Deux ou trois choses que je sais de la réécriture

La question est de savoir pourquoi et comment mobiliser la reecriture dans le travail de la classe de francais, et quels problemes cela pose. Pour ce faire, l'auteur opere un retour reflexif sur la notion de reecriture. Il repart des definitions possibles de la notion, en la situant par rapport a des notions connexes comme la "correction", la "revision" ou encore la "reformulation", en la caracterisant de l'interieur comme un lieu de tensions obligeant a des arbitrages delicats, en essayant de dresser une typologie des procedures de reecriture. Puis il passe en revue cinq modeles de reference propres a guider le travail de l? enseignant dans sa classe : le modele litteraire (le tissage dans l'ecriture effervescente) ; le modele genetique (le travail des brouillons) ; le modele cognitiviste (les processus redactionnels) et deux modeles plus specifiquement scolaires, qu? il appelle, faute de mieux, linguistico-didactique et pedagogico-didactique, selon qu'il(s) met(tent) l'accent sur les savoirs a construire ou sur le sujet scripteur. Pour conclure qu'il est urgent de reouvrir le debat si on veut clarifier les enjeux et les conditions de mise en oeuvre de la reecriture dans l'enseignement.
Coordinated Logistics with a Truck and a Drone

We determine the efficiency of a delivery system in which an unmanned aerial vehicle UAV provides service to customers while making return trips to a truck that is itself moving. In other words, a UAV picks up a package from the truck which continues on its route, and after delivering the package, the UAV returns to the truck to pick up the next package. Although the hardware for such systems already exists, the extent to which such an approach can actually provide a significantly improved quality of service is not yet understood. By combining a theoretical analysis in the Euclidean plane with real-time numerical simulations on a road network, we demonstrate that the improvement in efficiency is proportional to the square root of the ratio of the speeds of the truck and the UAV.

CTRP is essential for mosquito infection by malaria ookinetes

The malaria parasite suffers severe population losses as it passes through its mosquito vector. Contributing factors are the essential but highly constrained developmental transitions that the parasite undergoes in the mosquito midgut, combined with the invasion of the midgut epithelium by the malaria ookinete (recently described as a principal elicitor of the innate immune response in the Plasmodium‐infected insect). Little is known about the molecular organization of these midgut‐stage parasites and their critical interactions with the blood meal and the mosquito vector. Elucidation of these molecules and interactions will open up new avenues for chemotherapeutic and immunological attack of parasite development. Here, using the rodent malaria parasite Plasmodium berghei, we identify and characterize the first microneme protein of the ookinete: circumsporozoite‐ and TRAP‐related protein (CTRP). We show that transgenic parasites in which the CTRP gene is disrupted form ookinetes that have reduced motility, fail to invade the midgut epithelium, do not trigger the mosquito immune response, and do not develop further into oocysts. Thus, CTRP is the first molecule shown to be essential for ookinete infectivity and, consequently, mosquito transmission of malaria.
Anticancer activity of red pigment from Serratia marcescens in human cervix carcinoma.

The present study has been designed to analyse the anticancer property of microbial pigment prodigiosin isolated from waste sample of Serratia marcescens, a marine crustacean, against human cervix carcinoma cell (Hela-229 cell line). The cell lines were cultured in the DME medium along with various concentrations of prodigiosin for 24hrs and the percentage of cell viability was evaluated by 3-(4,5 dimethyl thiazol-2yl)-2,5 diphenyl tetrazolium bromide and neutral red. Prodigiosin showed dose dependent inhibition of cell proliferation. These results suggested that the prodigiosin has strong anticancer and apoptosis activity against human cervical carcinoma cancer.
Embedding NbN Nanowires Into Quantum Circuits With a Neon Focused Ion Beam

Parasitic two-level systems are generally present in superconducting circuits as a result of conventional fabrication and processing, and these lead to noise and loss of coherence in quantum systems. We examine the use of a Ne focused ion beam for producing nanowires integrated into superconducting circuits with a minimized density of parasitic two-level systems. We report measurements of nanowires produced by Ne focused-ion-beam milling in NbN resonators. The resonator losses increase after the nanowire is fabricated, with the Q factor decreasing by ~30% to ~10 5, which is a factor 10-100 higher than in the most closely comparable circuits previously measured. This indicates that the Ne focused ion beam is a promising route for creating superconducting-nanowire-based devices with low levels of decoherence.
The relation between otolith size and larval size at hatching for Atlantic cod, Gadus morhua*

We examined the relation- ship between otolith size and larval standard length (SL) at hatching for Atlantic cod, Gadus morhua, on the Scotian Shelf. We found a weak corre- lation between SL and area-based and radius-based measures of size of both lapillar and sagittal otoliths. Correla- tions of SL with the area of the lapillus were strongest. However, the predictive ability of all relationships was low. For example, the range of predicted SL at hatching of larvae with lapilli of aver- age area included more than 90% of observed SLs in newly hatched larvae from the Scotian Shelf collected over two spawning seasons. These results suggest that otolith-based attempts to backcalculate the size of cod larvae may be prone to substantial error if sizes of particularly young larvae are esti- mated. We recommend that, where pos- sible, stock- and season-specific esti- mates of the relationship between the area of the lapillus and larval size at hatching be used in back-calculation

A case study on learning through natural ways of interaction

This paper presents a case study on using different input modalities in the perspective of a more natural way of interaction. The use of hand gestures and voice commands in a learning environment compared to the conventional ways of interaction is considered a significant parameter for the users' experience. This study investigates the correlation between the learning styles of a number of participants with the input modality being used. To conduct the study, an application which provides different ways of interaction was designed, developed and utilized. The results have shown that the 2-D motion device was the most prominent, as far as time of completion was concerned, because the users were more familiar with it. On the contrary, the natural ways of interaction were proven to be the most exciting by all participants. It is recorded that the natural way of interaction impels learners to participate and increases their motivation and engagement in learning activities.
A set of microsatellite primers for Zostera japonica (Zosteraceae).

UNLABELLED PREMISE OF THE STUDY Polymorphic microsatellite primers were developed in the seagrass Zostera japonica to investigate genetic variation and to identify clonal structure. • METHODS AND RESULTS Thirteen polymorphic loci and 23 monomorphic loci were developed in Z. japonica. Two to 13 alleles per locus were observed at the polymorphic loci across 57 individuals of two Z. japonica populations. The observed and expected heterozygosities within populations ranged from 0.0000 to 1.0000 and from 0.0000 to 0.8542, respectively. • CONCLUSIONS Our study showed high-level polymorphism at the polymorphic loci in Z. japonica. These primers would be a powerful tool to study genetic variation, clonal structure, and mating systems.
A 1 V 5 mA Multimode IEEE 802.15.6/Bluetooth Low-Energy WBAN Transceiver for Biotelemetry Applications

This paper presents a 1 V multi-mode RF transceiver for wireless body area network (WBAN) applications. Operating in the 2.36 GHz Medical Body Area Networks (MBANs) and the 2.4 GHz Industrial, Scientific & Medical (ISM) frequency bands, the transceiver implements rotated differential-phase shift keying (DPSK) and Gaussian filtered frequency shift keying (GFSK) modulation for both IEEE 802.15. 6 Narrow Band (NB) and Bluetooth Low-Energy (LE) PHY standards. Also included is a proprietary 900 MHz ISM band transmitter utilizing FSK modulation. The wireless transceiver operates half-duplex, and for IEEE 802.15. 6 achieves -104/-96.5 dBm receiver input sensitivity (for 10% packet error rate) at data rates of 121.4/971.4 kbps and -94 dBm for Bluetooth LE (for 0.1% bit error rate) at 1 Mbps. Transmit power up to +3/+5 dBm is achievable for IEEE 802.15. 6 and Bluetooth LE respectively. The transceiver consumes 4.8 mA during IEEE 802.15. 6 & Bluetooth LE receive, and 4.6 mA during Bluetooth LE transmit at -10 dBm output power, from a 1.0 V supply. For IEE802.15. 6 transmission at -10 dBm output power, 5.9 mW is consumed, dropping to 1.7 mW for proprietary 900 MHz transmission. This performance surpasses state-of-the-art power consumption and represents the first published transceiver for the IEEE 802.15. 6 NB PHY standard. It is fabricated in a 0.13 μm CMOS technology and occupies approximately 5.9 mm2 .
Diphenyleneiodonium Triggers the Efflux of Glutathione from Cultured Cells*

Diphenyleneiodonium (DPI) is a broad-spectrum flavoprotein inhibitor commonly used to inhibit oxidant production by the NADPH oxidase of phagocytic and nonphagocytic cells. A previous study has shown that DPI can sensitize T24 bladder carcinoma cells to Fas-mediated apoptosis. We observed DPI to deplete intracellular reduced glutathione (GSH) in T24 cells and a range of other primary and transformed cell types. The effect was immediate, with 50% loss of intracellular GSH within 2 h of treatment with DPI. The glutathione was quantitatively recovered in the extracellular medium, indicating that efflux was occurring. The loss of GSH was blocked with bromosulfophthalein, an inhibitor of the canalicular GSH transporters. We conclude that DPI induces a dramatic efflux of cellular GSH from T24 cells via a specific transport channel. This provides a potential mechanism for its proapoptotic effect, and it also has important implications for the regulation of glutathione homeostasis in cells.
Reconstruction 3D et localisation similtanée de caméras mobiles : une approche temps-réel par ajustement de faisceaux local

Le probleme de la reconstruction 3D a partir d'une sequence d'images acquise par une camera en mouvement est un sujet important dans le domaine de la vision par ordinateur. Ce travail de these presente une methode qui permet d'estimer conjointement des points 3D de la scene filmee et le mouvement de la camera en combinant la precision des methodes "horsligne" (basees sur une optimisation globale de tous les parametres par ajustement de faisceaux) et la vitesse de calcul des methodes incrementales. La nouvelle approche est consideree comme une acceleration des techniques classiques de reconstruction 3D qui utilisent l'ajustement de faisceaux, permettant ainsi de traiter de longues sequences videos. L'algorithme developpe peut etre resume de la facon suivante : detection de points d'interet dans les images, mise en correspondance de ces points et sousechantillonnage temporel de la video. En effet, seul un sousensemble d'images dites "images clef" est selectionne pour la reconstruction des points 3D alors que la localisation de la camera est calculee pour chaque image. Le point clef de l'approche est l'ajustement de faisceaux local : les parametres de la reconstruction sont affines sur la fin de la sequence uniquement, a chaque fois qu'une image est choisie comme nouvelle image clef. La methode, initialement prevue pour les cameras perspectives, a ensuite ete generalisee de maniere a rendre possible l'utilisation d'autres types de cameras, comme les cameras catadioptriques ou encore les paires rigides de cameras. Les resultats obtenus montrent que la precision atteinte est du meme ordre que celle des methodes par optimisation globale, avec des temps de calcul tres reduits, ce qui permet de viser des applications d'odometrie visuelle temps reel pour la robotique mobile ou l'aide a la conduite en automobile.
