Control por modos deslizantes de un Sistema Híbrido de Almacenamiento de Energía para vehículos eléctricos

This paper presents a sliding mode control strategy for a Hybrid Energy Storage System (HESS) with a semi-active capacitor configuration, applied to electric vehicles. The system consists of a battery bank and ultracapacitor (UC) connected through a high efficiency DC-DC converter which controls the energy exchange with the rest of the system. The aim of HESS is to provide the power demand to the traction system, but taking care of the currents dynamics (or power) required to the battery, in order to preserve its lifetime. Experimental results are provided to verify the control strategy implemented in the HESS, using a pulsating load to represent the demands of a traction system.
Expression pattern of fibroblast growth factors (FGFs), their receptors and antagonists in primary endothelial cells and vascular smooth muscle cells

Fibroblast growth factors (FGFs) are important angiogenic growth factors. While basic FGF (FGF2) is well established as a potent inducer of angiogenesis much less is known about other FGFs possibly expressed by EC. We investigated the expression of all known FGFs, their main tyrosine kinase receptors and antagonists by RT-PCR analysis in human umbilical vascular endothelial cells (HUVECs) to obtain a complete expression profile of this important growth factor system in model endothelial cells (EC). In addition to FGFR1IIIc, which is considered as the major FGF receptor in EC, HUVECs express similar levels of FGFR3IIIc, detectable amounts of FGFR2IIIc and a new FGF receptor without an intracellular kinase domain (FGFR5). HUVECs express several secreted FGFs, including FGF5, 7, 8, 16 and 18 and two members of the fibroblast growth factor homologous factors (FHFs), not yet reported to be expressed in EC. The expression panel was compared with that obtained from human vascular smooth muscle cells (VSMCs) and human aortic tissue. Human umbilical artery smooth muscle cells (HUASMCs) and HUVECs express the identical FGF receptor and ligand panel implicating that both cell types act, according the FGF signals more as an entity than as individual cell types. Expression of Fgf1, 2, 7, 16 and 18 and the antagonists Sprouty 2,3 and 4 was demonstrated for all analysed cDNAs. The IIIc isoforms of FGFR1 and 2 and the novel FGFR5 were expressed in the aorta, but expression of the FGF receptor 3 was not detected in cDNAs derived from aortic tissue. In the VSMC of rat aortic tissue and in HUASM cultured cells we could demonstrate FGF18 immunoreactivity in the nucleus of the cells. The expression of several secreted FGFs by EC may focus the view more on their paracrine effects on neighbouring cells during tissue regeneration or tumor formation.
Resolution limits of ultrafast ultrasound localization microscopy

As in other imaging methods based on waves, the resolution of ultrasound imaging is limited by the wavelength. However, the diffraction-limit can be overcome by super-localizing single events from isolated sources. In recent years, we developed plane-wave ultrasound allowing frame rates up to 20 000 fps. Ultrafast processes such as rapid movement or disruption of ultrasound contrast agents (UCA) can thus be monitored, providing us with distinct punctual sources that could be localized beyond the diffraction limit. We previously showed experimentally that resolutions beyond λ/10 can be reached in ultrafast ultrasound localization microscopy (uULM) using a 128 transducer matrix in reception. Higher resolutions are theoretically achievable and the aim of this study is to predict the maximum resolution in uULM with respect to acquisition parameters (frequency, transducer geometry, sampling electronics). The accuracy of uULM is the error on the localization of a bubble, considered a point-source in a homogeneous medium. The proposed model consists in two steps: determining the timing accuracy of the microbubble echo in radiofrequency data, then transferring this time accuracy into spatial accuracy. The simplified model predicts a maximum resolution of 40 μm for a 1.75 MHz transducer matrix composed of two rows of 64 elements. Experimental confirmation of the model was performed by flowing microbubbles within a 60 μm microfluidic channel and localizing their blinking under ultrafast imaging (500 Hz frame rate). The experimental resolution, determined as the standard deviation in the positioning of the microbubbles, was predicted within 6 μm (13%) of the theoretical values and followed the analytical relationship with respect to the number of elements and depth. Understanding the underlying physical principles determining the resolution of superlocalization will allow the optimization of the imaging setup for each organ. Ultimately, accuracies better than the size of capillaries are achievable at several centimeter depths.
Relation between income inequality and mortality in Canada and in the United States: cross sectional assessment using census data and vital statistics

Abstract Objective: To compare the relation between mortality and income inequality in Canada with that in the United States. Design: The degree of income inequality, defined as the percentage of total household income received by the less well off 50% of households, was calculated and these measures were examined in relation to all cause mortality, grouped by and adjusted for age. Setting: The 10 Canadian provinces, the 50 US states, and 53 Canadian and 282 US metropolitan areas. Results: Canadian provinces and metropolitan areas generally had both lower income inequality and lower mortality than US states and metropolitan areas. In age grouped regression models that combined Canadian and US metropolitan areas, income inequality was a significant explanatory variable for all age groupings except for elderly people. The effect was largest for working age populations, in which a hypothetical 1% increase in the share of income to the poorer half of households would reduce mortality by 21 deaths per 100 000. Within Canada, however, income inequality was not significantly associated with mortality. Conclusions: Canada seems to counter the increasingly noted association at the societal level between income inequality and mortality. The lack of a significant association between income inequality and mortality in Canada may indicate that the effects of income inequality on health are not automatic and may be blunted by the different ways in which social and economic resources are distributed in Canada and in the United States.
Laparoscopic right nephrectomy for live kidney donation: functional results

Laparoscopic live-donor nephrectomy has gained wide acceptance. However, the vast majority of surgeons perform left nephrectomies only, which may not always be in the best interest of the donor. Of 17 consecutive laparoscopic donor nephrectomies, 13 were done on the right side. The function of these grafts was compared with that of 17 kidneys previously procured by an open technique and with that of the four left laparoscopic grafts. Ischaemic damage was evaluated by post-operative nuclear scanning and urinary lysozyme, and graft function by creatinine and creatinine clearance. Results show that operating time was longer in the laparoscopic donors, but identical in right and left laparoscopic procurements. Ischaemic damage and function were similar, regardless of the side or the surgical technique. We can conclude that right laparoscopic donor nephrectomy is feasible and results in good graft function. Systematic harvesting from the left side may, therefore, not be justified.
Alteration in surface ion composition of cultured bone during metabolic, but not respiratory, acidosis.

Acidosis produced by a fall in [HCO3-] (metabolic acidosis, Met) produces greater Ca efflux from cultured bone than that produced by a rise in PCO2 (respiratory acidosis, Resp). To compare the effects of Met and Resp on bone surface ion composition we measured the surface abundance of 40Ca, 23Na, and 39K in cultured bone with a scanning ion microprobe utilizing secondary-ion mass spectrometry. Neonatal mouse calvariae were incubated for 24 h in medium simulating either Met (pH = 7.193 +/- 0.034, [HCO3-] = 15.1 +/- 1.4 meq/l), Resp (pH = 7.153 +/- 0.014, PCO2 = 85.4 +/- 1.2 mmHg) or normal physiological (Ctl; pH = 7.484 +/- 0.009, [HCO3-] = 29.7 +/- 0.7, PCO2 = 39.6 +/- 0.3) conditions. The surface of Ctl at 2-nm depth is rich in Na and K relative to Ca (Na/Ca = 25.6, K/Ca = 12.0, ratios of counts/s of secondary ions). Compared with Ctl, Met produced a sharp fall in both Na/Ca (6.5, P less than 0.01) and K/Ca (4.6, P less than 0.01), whereas Resp did not alter Na/Ca (23.8) or K/Ca (15.0). Ca efflux was greater in Met (873 +/- 54 nmol.bone-1.24 h-1) than in Resp (546 +/- 71 nmol.bone-1.24 h-1, P less than 0.01), which was greater than that in Ctl (315 +/- 49 nmol.bone-1.24 h-1, P less than 0.01 vs. Met and vs. Resp).

L’aspiration des voies respiratoires est realisee dans l’ensemble des services cliniques de l’hopital pediatrique Debrousse. Les couts engendres par cette activite et les demandes du CLIN local nous ont amenes a dresser un etat des lieux descriptif de cet acte. Une enquete de pratique par questionnaire et des reunions pluridisciplinaires ont permis de mettre en evidence des non-conformites par rapport aux recommandations d’hygiene, concernant notamment les frequences d’entretien et de changement des differents dispositifs medicaux du circuit. Quatre types de montages ont ete identifies, avec des couts variant de 2,66 a 6,79 euros par 24 heures. Suite a cet etat des lieux, un protocole d’hygiene a ete redige par la pharmacie. De plus, des criteres de choix pour les dispositifs medicaux utilises ont ete recueillis, en vue de proposer de nouveaux produits adaptes aux exigences de la pediatrie ou d’ameliorer les montages existants. Ces demarches s’inscrivent dans une rationalisation des pratiques, tant sur le plan economique que sur celui de la lutte contre les infections nosocomiales.
LDP Lean Document Production - O.R.-Enhanced Productivity Improvements for the Printing Industry

Xerox has invented, tested, and implemented a novel class of operations-research-based productivity-improvement offerings, trademarked LDP Lean Document Production® solutions, for the $100 billion printing industry in the United States. These solutions, which Xerox has implemented in approximately 100 sites to date, have provided dramatic productivity and cost improvements for both print shops and document-manufacturing facilities, as measured by reductions of 20--40 percent in revenue-per-unit labor cost. They have generated approximately $200 million of incremental profit across the Xerox customer value chain since their initial introduction in 2000. The offerings have extended the use of operations research to small-and medium-sized print shops, while increasing the scope of its application to large document-production facilities.
By The People: A History of Americans as Volunteers

Most history books paint our past with portraits of presidents, generals, and captains of industry. By the People introduces the multitude of citizens who stood on the front lines when history was being made--the volunteers and associates that shaped us as a people, from the Social Compact of 1620 to the Underground Railroad before the Civil War and the women's suffrage movement.
Análise de métodos de Inferência Ecológica em dados de redes sociais

Redes Sociais Online se tornaram extremamente populares e têm gerado um enorme volume de dados. Saber as características demográficas desses usuários pode ser útil, por exemplo, para direcionamento de campanhas de marketing. Ao contrário da maioria das abordagens, nós propomos a utilização de Inferência Ecológica para entender características demográficas para grupos de pessoas. Nossos resultados mostram que é possível inferir gênero e idade utilizando apenas o censo do IBGE e informações agregadas obtidas de uma rede social, como a quantidade agregada de pessoas que apoiam um candidato político.
Femtosecond excitation of nonthermal carrier populations in GaAs quantum wells.

We report the first direct observation of nonthermal photoexcited carrier distributions in GaAs quantum-well structures. We present experimental studies which show that these distributions thermalize within 200 fs. In addition we are able to show that near the band edge the effect of long-range Coulomb screening on the bleaching of the two-dimensional-exciton resonances is much weaker than that of the Pauli exclusion principle.

Preservation and augmentation of molar extraction sites affected by severe bone defect due to advanced periodontitis: A prospective clinical trial

BACKGROUND Studies of the extracted infected-molar ridge preservation are limited. PURPOSE To compare alterations of hard and soft tissue in infected-molar sockets receiving ridge preservation compared with natural healing. MATERIALS AND METHODS Thirty-five infected-molar extraction sites either preserving with Bio-Gide membrane covered the Bio-Oss material or receiving natural healing procedure as controls. The soft tissue profile was evaluated before tooth extraction and after 6-month healing. Cone-beam computed tomography scans were taken immediately and 6 months after extraction. Vertical and horizontal bone changes were assessed radiographically. Data were analyzed with Mann-Whitney U test and α = 0.05. RESULTS No significant differences in soft tissue and vertical bone changes in the medium region of the sockets were found (P > .05). Buccal bone changes in the mesial and distal sites in the test group were significantly lower than the control group (P < .05). Ridge width increased from 0.21mm to 5.30mm at 1mm apical from the crest in the test and reduced from 0.12 mm to 1.00 mm in the control groups. CONCLUSION Ridge preservation at periodontally compromised molar extraction sites might compensate for ridge width and buccal bone resorption that occurs with natural healing alone.
Management of spinal cord compression #238.

veals if there is compression of the cord versus nerve roots and can provide useful information about the spine’s stability. Computed tomography (CT) myelography has sensitivity and specificity close to that of MRI, and can be used in patients who cannot get an MRI. Plain films are not sensitive and cannot rule out either vertebral metastases or SCC. If they show vertebral lesions in a suspected area, however, that should increase one’s suspicion of SCC and prompt further investigation. Bone and positron emission tomography (PET) scans can show the presence of vertebral metastases but do not provide information about compression of the spinal cord. CT scans are not recommended due to poor revelation of the epidural space and spinal cord.
Cdc42 is crucial for the establishment of epithelial polarity during early mammalian development

To study the role of Cdc42 in the establishment of epithelial polarity during mammalian development, we generated murine Cdc42‐null embryonic stem cells and analyzed peri‐implantation development using embryoid bodies (EBs). Mutant EBs developed endoderm and underlying basement membrane, but exhibited defects of cell polarity, cell–cell junctions, survival, and cavitation. These defects corresponded to a decreased phosphorylation and membrane localization of aPKC, a reduced phosphorylation of GSK3β, and a diminished activity of Rac1. However, neither Rac1 nor the kinase function of GSK3β seem to contribute to cell polarization and cell–cell contacts. In contrast, EBs expressing dominant‐negative (dn) PKCζ mimicked well the phenotype of Cdc42‐null EBs, suggesting a major role of aPKC in mediating cell polarization downstream of Cdc42. Finally, aggregation experiments with endodermal cell lines suggested that Cdc42 might affect formation of adherens and tight junctions by PKCζ‐dependent regulation of the protein levels of p120 catenin and E‐cadherin.

Design of a functionally equivalent nonglycosylated analog of the glycopeptide antibiotic formaecin I

Various nonglycosylated analogs were designed in order to explore the role of glycosylation in formaecin I, an antibacterial glycopeptide of insect origin. The functional behavior of a designed nonglycosylated analog (P7,endo P8a,ΔT11)formaecin I was found to be similar to that of native glycosylated peptide. Both the peptides showed similar antibacterial activities against Escherichia coli and Salmonella strains. The designed nonglycosylated analog (P7,endo P8a,ΔT11)formaecin I has low binding affinity to LPS identical to that of native glycopeptide, formaecin I. Both the peptides have similar killing kinetics and are nontoxic to erythrocytes. Formaecin I and designed nonglycosylated (P7,endo P8a,ΔT11)formaecin I have no definite conformational features associated with them. The glycosylated residue of threonine in formaecin I and proline residues in designed peptide [(P7,endo P8a,ΔT11)formaecin I], possibly help in stabilizing the correct conformation that facilitates presentation of the peptide to its receptor. It is evident that a functionally equivalent nonglycosylated analog of native glycosylated antibacterial peptide can be designed by strategically modifying the sequence.
Clinometric properties of a clinical spasticity measurement tool

Purpose. To investigate clinometric properties of an Anglo-Dutch spasticity measurement tool (ADSMT), an objective tool providing information about both neurophysiological and biomechanical aspects of spasticity about the wrist joint in the clinical setting. Method. ADSMT measurements were performed with 12 healthy and 11 participants with post-stroke spasticity, and consisted of assessing the maximum range of passive wrist movement (pROM) and passive wrist extension at different cycle rates. Outcome measures were wrist angle, flexor and extensor activation, and resistance to movement. Intra-class Correlation Coefficients (ICCs) were calculated for inter-rater and test-retest reliability. Validity was investigated by calculating Spearman's rho between ADSMT outcome measures and the Modified Ashworth Scale (n = 12), the Action Research Arm Test (n = 6), and a validated wrist rig (n = 6). Results. Impaired participants had higher flexor activity and higher resistance to movement during passive wrist extension compared to unimpaired participants. For all outcome measures inter-rater and test-retest reliability were satisfactory to good and concurrent validity was sufficient. Conclusions. Outcome measures related to wrist flexor activity and resistance to movement during extension are promising for spasticity assessment using the ADSMT. Further knowledge on reference values and practicality is necessary for this tool to become incorporated in the clinical setting.
Supply chain coordination with revenue sharing contract and lateral transshipment

We construct a two-echelon supply chain with one supplier and two retailers. Revenue sharing contract and lateral transshipment are considered in the discussed supply chain. We present a game model, and study how lateral transshipment under revenue sharing contract affects retailers' inventory choices and supply chain profit. Retailers choose their inventory levels by considering the possibility of transshipments to maximize their own profits under revenue sharing contract. We find that transshipment combined with revenue sharing contract can coordinate the discussed supply chain, and improve the performance of all the supply chain actors.
