Authors: Azeez Hemin Ismael , Ahmed Shorsh Kareem , Husain Mohamed Abdullah 
Published: March 2017

A dual band F-shaped printed mono-pole antenna (USB dongle) with two meandered strips is proposed and tested. The two strips that resonating at 2.45 GHz and 5.2 GHz have uniform and fixed width of 0.5 mm. A thin layer of 0.8 mm thickness FR4 substrate (permittivity =4.4, loss tangent=0.0245) which is economically cheap is used for the unit fabrication. The two resonant modes will best support Bluetooth (BT) and WLAN (Wireless Local Area Network) having enough supportive bandwidth which is defined by -10dB reflection coefficient. The proposed unit is low profile, compact and simple to fabricate. The whole unit that has an overall size of (0.8mm x 10 mm x 40 mm) is efficient for having 97% and 94 % total radiation efficiency at both operating frequencies respectively. Through applying different simulation scenarios to the unit such as varying the feeding location and changes in the strips length, it has been revealed that the antennas is sensitive and reactive. The proposed antenna has provided good performance and Omni-directional radiation pattern. Good matching between the simulated and measured reflection coefficient results for the antenna prototype has been achieved.

Abstract
The cyclic behavior of (O–C) residuals of eclipse timings in the sdB+M eclipsing binary NSVS 14256825 was previously attributed to one or two Jovian-type circumbinary planets. We report 83 new eclipse timings that not only fill in the gaps in those already published but also extend the time span of the (O–C) diagram by three years. Based on the archival and our new data spanning over more than 17 years, we re-examined the up-to-date system (O–C). The data revealed a systematic, quasi-sinusoidal variation deviating from an older linear ephemeris by about 100 s. It also exhibits a maximum in the (O–C) near JD 2,456,400 that was previously unknown. We consider two most credible explanations of the (O–C) variability: the light propagation time due to the presence of an invisible companion in a distant circumbinary orbit, and magnetic cycles reshaping one of the binary components, known as the Applegate or Lanza–Rodonó effect. We found that the latter mechanism is unlikely due to the insufficient energy budget of the M-dwarf secondary. In the framework of the third-body hypothesis, we obtained meaningful constraints on the Keplerian parameters of a putative companion and its mass. Our best-fitting model indicates that the observed quasi-periodic (O–C) variability can be explained by the presence of a brown dwarf with the minimal mass of 15 Jupiter masses rather than a planet, orbiting the binary in a moderately elliptical orbit (

) with a period of ∼10 years. Our analysis rules out the two-planet model proposed earlier.
The Exoplanet Simple Orbit Fitting Toolbox (ExoSOFT): An Open-source Tool for Efficient Fitting of Astrometric and Radial Velocity Data
Authors: Mede Kyle , Brandt Timothy D. 
Published: March 2017

Abstract
We present the Exoplanet Simple Orbit Fitting Toolbox (ExoSOFT), a new, open-source suite to fit the orbital elements of planetary or stellar-mass companions to any combination of radial velocity and astrometric data. To explore the parameter space of Keplerian models, ExoSOFT may be operated with its own multistage sampling approach or interfaced with third-party tools such as emcee. In addition, ExoSOFT is packaged with a collection of post-processing tools to analyze and summarize the results. Although only a few systems have been observed with both radial velocity and direct imaging techniques, this number will increase, thanks to upcoming spacecraft and ground-based surveys. Providing both forms of data enables simultaneous fitting that can help break degeneracies in the orbital elements that arise when only one data type is available. The dynamical mass estimates this approach can produce are important when investigating the formation mechanisms and subsequent evolution of substellar companions. ExoSOFT was verified through fitting to artificial data and was implemented using the Python and Cython programming languages; it is available for public download at https://github.com/kylemede/ExoSOFT under GNU General Public License v3.
Planetary Nebulae that Cannot Be Explained by Binary Systems
Authors: Bear Ealeal , Soker Noam 
Published: March 2017

Abstract
We examine the images of hundreds of planetary nebulae (PNe) and find that for about one in six PNe the morphology is too “messy” to be accounted for by models of stellar binary interaction. We speculate that interacting triple stellar systems shaped these PNe. In this preliminary study, we qualitatively classify PNe by one of four categories. (1) PNe that show no need for a tertiary star to account for their morphology. (2) PNe whose structure possesses a pronounced departure from axial-symmetry and/or mirror-symmetry. We classify these, according to our speculation, as “having a triple stellar progenitor.” (3) PNe whose morphology possesses departure from axial-symmetry and/or mirror-symmetry, but not as pronounced as in the previous class, and are classified as “likely shaped by triple stellar system.” (4) PNe with minor departure from axial-symmetry and/or mirror-symmetry that could have been also caused by an eccentric binary system or the interstellar medium. These are classified as “maybe shaped by a triple stellar system.” Given a weight η

t
= 1, η

l
= 0.67, and η

m
= 0.33 to classes 2, 3, and 4, respectively, we find that according to our assumption about 13%–21% of PNe have been shaped by triple stellar systems. Although in some evolutionary scenarios not all three stars survive the evolution, we encourage the search for a triple stellar systems at the center of some PNe.

Published: March 2017

Position du problème : Estimer l’impact économique (coût pour l’hôpital) des injections de toxine botulique dans la prise en charge des patients paralysés cérébraux marchants présentant une spasticité des membres inférieurs. Méthodes : Enfants inclus dans l’observatoire Botuloscope, multicentrique, évaluant une série consécutive d’enfants paralysés cérébraux âgés entre 2 et 16 ans présentant une spasticité focale invalidante. L’étude de coût a été réalisée dans la perspective de l’hôpital. Les coûts directs hospitaliers (année 2004) étaient ceux induits par l’utilisation de la toxine botulique à 12 mois en MCO et SSR. Résultats : Deux cent quarante enfants ont été inclus, 486 séances d’injection de toxine ont été réalisées pendant l’année de suivi. Le coût moyen de la seule séance d’injection (toxine + analgésie + consultation ou hospitalisation) a été estimé pour l’ensemble des enfants à 731 € par enfant, dont plus de la moitié pour la toxine et l’analgésie. Sur 12 mois, le coût hospitalier de la prise en charge des enfants a été estimé à un peu plus de 2 500 € par enfant. Conclusion : S’il existe depuis 2009 un Groupe Homogène de Malades (GHM) spécifique pour l’injection de toxine en ambulatoire, valorisé à 375,55 € en 2014, ce remboursement ne couvre pas le coût moyen d’une séance d’injection tel que nous avons pu le calculer. Le tarif du GHM ne tient en effet pas compte (1) du nombre de muscles injectés, (2) du nombre de membres traités (3) du niveau de dépendance du patient, (4) des doses de toxine injectée, et (5) de la nécessité d’une procédure antalgique lourde ou non. Conflit d’intéret : aucun.
Chapter 2. Bioethics as respect and love of life some reflections on Fritz Jahr’s thought
Authors: Tai Michael Cheng-tek 
Published: March 2017

L’humanité parle de l’éthique dans le noble but de l’amélioration et de la mise en valeur des relations humaines entre personnes. Il ne serait pas question d’éthique si le souci et l’intérêt pour autrui n’existaient pas. Il est évident que le fondement de l’éthique est un souci réciproque entre des individus. Cet intérêt, cependant, a été élargi pour inclure toute forme de vie sur terre. Par conséquent un nouveau terme ‘bioéthique’ a été inventé. Comme l’a dit Fritz Jahr, nous devons respecter chaque être vivant. Ainsi, qu’est la bioéthique ? Elle est le respect et l’amour de la vie.
Chapter 4. Fritz Jahr and global bioethics analyses and reflections from the perspective of islamic tradition
Authors: Ilkilic Ilhan , Ertin Hakan , Brömer R. 
Published: March 2017

La maxime de Fritz Jahr selon laquelle il faut « Respecter tout être vivant comme une fin en soi et le traiter, si possible, en tant que telle », fut publiée pour la première fois dans un essai de 1927 dans lequel il a également introduit le terme « bioéthique ». Cette maxime est analysée ici de la perspective de la tradition islamique. La conception islamique d’humain, d’animal et de plante est présentée et les normes centrales appliquées au traitement des animaux et des plantes sont examinées du point de vue de leurs implications pratiques. Finalement, l’applicabilité de la notion normative de Jahr de « fin en soi » peut être appliquée au traitement des animaux et des plantes dans le contexte de la bioéthique islamique. Cette discussion tente de répondre à la question quant à savoir si une bioéthique globale peut être développée.

Authors: An Yu Fei , Peretti Jean-Marie 
Published: March 2017

La communication des entreprises sur leurs politiques et pratiques de RSE (Responsabilité Sociétale de l’Entreprise) vise à fonder des représentations de l’entreprise et de ses responsabilités et asseoir la légitimité de leurs dirigeants. L’analyse comparative des rapports RSE publiés par des entreprises chinoises et françaises fait ressortir la diversité des thèmes abordés et les spécificités nationales des enjeux respectifs en termes de communication RSE. Cet article, en s’appuyant sur l’analyse de quatre rapports RSE 2013 d’entreprises chinoises cotées et sur les premiers bilans de l’application en 2013 en France de l’article 225 de la loi « Grenelle 2 » qui a redéfini les informations sociales, environnementales, sociétales et sociétale à publier par les entreprises cotées, a pour objectif de dégager des similitudes et des différences dans la façon de rendre compte du social, du sociétal et de l’environnemental par les entreprises cotées en France et en Chine.
Les raisons de la réussite du Guide Michelin au Japon
Authors: Poullennec Gwendal 
Published: March 2017

Le Guide Parker, le classement de Shanghai, les notes de Fitch ou de Moody’s sont aujourd’hui des références mondiales. En matière de gastronomie, la bible est le Guide Michelin. Comment cette institution tellement française, si éminemment locale dans son histoire et sa conception, a-t-elle pu s’imposer dans d’autres cultures ? L’exemple du Japon montre qu’à côté de qualités universelles comme l’objectivité et l’indépendance, se joue aussi une rencontre interculturelle, qui seule permet une réelle appropriation du produit.
Multiplication des canaux et valeur perçue de l’offre digitale dans la presse écrite : un effet de complémentarité ?
Authors: Rivière Arnaud , Mencarelli Rémi , Belvaux Bertrand , Pallud Jessie 
Published: March 2017

Comme de nombreux secteurs, la presse écrite est touchée par l’apparition de canaux numériques. Cela a favorisé l’émergence de nouvelles manières d’accéder à l’information et a contribué au développement de nouveaux contenus. Les dernières réflexions académiques et managériales conduisent à supposer l’existence d’un effet de complémentarité entre les contenus comme entre les canaux. Cette recherche se propose de vérifier cette hypothèse à partir d’une enquête menée auprès de 1 028 lecteurs du journal Le Monde. Les résultats mettent seulement à jour un effet de complémentarité entre les canaux, et uniquement sous certaines conditions.
Glucose-Dependent Insulinotropic Polypeptide Receptor Deficiency Leads to Impaired Bone Marrow Hematopoiesis
Authors: Mantelmacher Fernanda Dana , Fishman Sigal , Cohen Keren , Pasmanik Chor Metsada , Yamada Yuichiro , Zvibel Isabel , Varol Chen 
Published: March 2017

Abstract
The bone marrow (BM) contains controlled specialized microenvironments, or niches, that regulate the quiescence, proliferation, and differentiation of hematopoietic stem and progenitor cells (HSPC). The glucose-dependent insulinotropic polypeptide (GIP) is a gut-derived incretin hormone that mediates postprandial insulin secretion and has anabolic effects on adipose tissue. Previous studies demonstrated altered bone microarchitecture in mice deficient for GIP receptor (Gipr−/−), as well as the expression of high-affinity GIP receptor by distinct cells constructing the BM HSPC niche. Nevertheless, the involvement of GIP in the process of BM hematopoiesis remains elusive. In this article, we show significantly reduced representation and proliferation of HSPC and myeloid progenitors in the BM of Gipr−/− mice. This was further manifested by reduced levels of BM and circulating differentiated immune cells in young and old adult mice. Moreover, GIP signaling was required for the establishment of supportive BM HSPC niches during HSPC repopulation in radioablated BM chimera mice. Finally, molecular profiling of various factors involved in retention, survival, and expansion of HSPC revealed significantly lower expression of the Notch-receptor ligands Jagged 1 and Jagged 2 in osteoblast-enriched bone extracts from Gipr−/− mice, which are important for HSPC expansion. In addition, there was increased expression of CXCL12, a factor important for HSPC retention and quiescence, in whole-BM extracts from Gipr−/− mice. Collectively, our data suggest that the metabolic hormone GIP plays an important role in BM hematopoiesis.

AbstractSoluble factors released from platelets can modulate the immune response of leukocytes. We and others have recently found that T lymphocytes with bound platelets have reduced proliferation and IFN-γ and IL-17 production. Thus, we speculate that if we induce the binding of platelets to lymphocytes, we will be able to regulate the inflammatory response. When we cocultured platelets with lymphocytes at different ratios, we were able to increase the percentage of lymphocytes with bound platelets. The coculture of platelets with lymphocytes in the presence of stimulation decreased the production of IFN-γ and TNF-α, T cell proliferation, and the expression of CD25, PD-L1, and SLAM. However, this coculture increased CD39 expression. All of these effects were dependent on the dose of platelets and operated indistinctly with platelets from different healthy donors. When platelets were cocultured in the same compartment with lymphocytes, we observed less IFN-γ and TNF-α production and T lymphocyte proliferation than in cultures with platelets separated from lymphocytes by a 0.4-μm pore size filter. The binding of platelets to lymphocytes was blocked with anti–P-selectin Abs, and when this occurred we observed higher IFN-γ and TNF-α production than in nonblocked conditions. The cocultures of platelets with synovial fluid cells from rheumatoid arthritis patients reduced inflammatory cytokine production and increased IL-10 production. These results suggest that platelet binding to lymphocytes effectively regulates T lymphocyte function. This mechanism could be easily applied to reduce inflammatory responses.

<p>Nearshore sediments have a major influence over the functioning of aquatic ecosystems, but predicting their response to future environmental change has proven difficult. Previous manipulative experiments have faced challenges controlling environmental conditions, replicating sediment mixing dynamics, and extrapolating across spatial scales. Here we describe a new approach to manipulate lake sediments that overcomes previous concerns about reproducibility and environment controls, whilst also bridging the gap between smaller microcosm or litterbag experiments and whole-ecosystem manipulations. Our approach involves submerging moderate-sized (~15 L) artificial substrates that have been standardised to mimic natural sediments within the littoral zones of lakes. We show that this approach can accurately mirror the absolute dissolved organic carbon concentrations and pH of pore water, and to a lesser degree inorganic carbon concentrations, from natural lake sediments with similar organic matter profiles. On a relative basis, all measured variables had similar temporal dynamics between artificial and adjacent natural sediments. Late-summer zooplankton biomass also did not differ between natural and artificial sediments. By offering a more realistic way to manipulate freshwater sediments than previously possible, our approach can improve predictions of lake ecosystems in a changing world.<br /><br /><img src="/public/site/images/ttaccini/88x31.png" alt="" /> <br />This work is licensed under a <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank">Creative Commons Attribution 4.0 International</a>.</p>
A Preliminary Multifactorial Approach Describing the Relationships Among Lower Extremity Alignment, Hip Muscle Activation, and Lower Extremity Joint Excursion
Authors: Nguyen Anh-Dung , Shultz Sandra J. , Schmitz Randy J. , Luecht Richard M. , Perrin David H. 
Published: March 2017

Context: Multiple factors have been suggested to increase the risk of faulty dynamic alignments that predict noncontact anterior cruciate ligament injury. Few researchers have examined this relationship using an integrated, multifactorial approach.Objective: To describe the relationship among static lower extremity alignment (LEA), hip muscle activation, and hip and knee motion during a single-leg squat.Design: Descriptive laboratory study.Setting: Research laboratory.Patients or Other Participants: Thirty men (age = 23.9 ± 3.6 years, height = 178.5 ± 9.9 cm, mass = 82.0 ± 14.1 kg) and 30 women (age = 22.2 ± 2.6 years, height = 162.4 ± 6.3 cm, mass = 60.3 ± 8.1 kg).Main Outcome Measure(s): Pelvic angle, femoral anteversion, quadriceps angle, tibiofemoral angle, and genu recurvatum were measured to the nearest degree; navicular drop was measured to the nearest millimeter. The average root mean square amplitude of the gluteus medius and maximus muscles was assessed during the single-leg squat and normalized to the peak root mean square value during maximal contractions for each muscle. Kinematic data of hip and knee were also assessed during the single-leg squat. Structural equation modeling was used to describe the relationships among static LEA, hip muscle activation, and joint kinematics, while also accounting for an individual's sex and hip strength.Results: Smaller pelvic angle and greater femoral anteversion, tibiofemoral angle, and navicular drop predicted greater hip internal-rotation excursion and knee external-rotation excursion. Decreased gluteus maximus activation predicted greater hip internal-rotation excursion but decreased knee valgus excursion. No LEA characteristic predicted gluteus medius or gluteus maximus muscle activation during the single-leg squat.Conclusions: Static LEA, characterized by a more internally rotated hip and valgus knee alignment and less gluteus maximus activation, was related to commonly observed components of functional valgus collapse during the single-leg squat. This exploratory analysis suggests that LEA does not influence hip muscle activation in controlling joint motion during a single-leg squat.
Microdialysis and Delivery of Iontophoresis-Driven Lidocaine Into the Human Gastrocnemius Muscle
Authors: Coglianese Mark , Draper David O. , Shurtz Joseph , Mark Gary 
Published: March 2017

Context: Iontophoresis is used frequently in physical medicine and rehabilitation, but many research techniques do not adequately measure it for depth of medicine delivery.
Objective: To determine if iontophoresis delivers lidocaine 5 mm under the surface of human skin.
Design: Descriptive laboratory study.
Setting: Therapeutic modalities research laboratory.
Patients or Other Participants: Eight men and 5 women volunteers (age range = 21 ± 2.3 years) who had less than 5 mm of adipose tissue in the area we measured participated in the study.
Intervention(s): We inserted a microdialysis probe 5 mm under the skin of both legs and into the triceps surae muscle groups of 10 participants. Microdialysis was performed for 60 minutes to allow a recovery period for local skin blood flow to return to baseline. We then delivered 2 mL of 1% lidocaine to the treatment leg via iontophoresis at 40 mA/min. Next, microdialysis was performed continuously in both legs during the treatment and for 30 minutes posttreatment to collect the lidocaine samples. After we had gathered the samples, several saline solutions with various amounts of lidocaine (0.005%, 0.025%, 0.05%, and 0.1%) were prepared in vitro and analyzed. Although we did not intend to do so as a part of the original study, we also performed an identical follow-up study at 3 mm in 3 participants.
Main Outcome Measure(s): Both in vitro and in vivo samples were analyzed via reverse-phase high-performance liquid chromatography (RP-HPLC). A protocol for detection and quantification of lidocaine using RP-HPLC was followed.
Results: We did not detect any measurable levels or concentrations of lidocaine in the 10 control samples. According to the RP-HPLC analysis, the 10 treatment samples also were negative for the presence of lidocaine. However, when we performed the study at 3 mm, microdialysis detected lidocaine in the 3 participants at this depth in the treatment leg only.
Conclusions: Measurable levels of lidocaine were not detected at 5 mm but were found at 3 mm. More studies are needed to determine the efficacy of microdialysis in measuring iontophoresis-delivered compounds.
