La structure spatiale et temporelle de l’entomofaune circulante comme indicateur biologique dans la gestion des forêts et des prairies

Les auteurs se proposent ici d'illustrer l'interet des approches globales en considerant le compartiment entomologique circulant dans son ensemble. A ce titre, les resultats de deux etudes menees dans le cadre du suivi dynamique de deux series vegetales soumises a une gestion humaine sont presentes. La methodologie repose sur l'utilisation d'un piege d'interception composite, le P.E. C, (Piege Entomologique Composite), ainsi que sur une approche taxinomique englobante pour laquelle le niveau systematique de la famille s'avere valide pour la realisation de diagnoses ecologiques a forte signification fonctionnelle. L'interet de ces recherches, outre l'originalite des resultats obtenus, permet de jeter les bases d'une approche detaillee et reproductible des caracteristiques tant fonctionnelles que structurelles des ecosystemes terrestres, ceci avec une precision spatiotemporelle tres fine et des moyens relativement modestes.
Decisioning based on the non-deterministic areas Instead of deterministic positioning In non-stationary environments For Robot Agents

One of the most important parts in designing anonymous intelligent robot agents is to determine where the robot is positioned. In case the robot agent is designed to operate in nonstationary environments, the results of this section are of great importance; because the results originated from positioning are directly used in intelligent layers. Decisioning in most common methods, for intelligent robot agents are being done using exact values (resulting from positioning) where gaining exact values require heavy algorithms and high processing. In this document we have tried to point out the causes and benefits of changing this method and substituting the nondeterministic areas instead of deterministic positioning. Here, instead of decisioning based on the deterministic positioning of each agent, decisioning is based on the area of which the agent is positioned in the environment. These environments getting affected by the agent’s position and the environment’s parameters at each moment are the basis of the team’s basic movements and decisioning in the agent’s intelligent structure.
OBSTETRICIANS’ TACTICS IN THE DELIVERY BY PATIENTS WITH BREECH POSITION OF THE FOETUS AFFECTED BY THE UTERINE MYOMA

The aim of the study – improvement of pregnancy outcomes in women with pelvic presentation on the background of uterine myoma by developing optimal obstetric delivery tactics. Materials and Methods. In order to achieve the stated goal, a prospective analysis of cases of first- and second-time delivering patients with full-term one fetus pregnancy in pelvic presentation (incomplete and complete) amid the uterine myoma – the main group (MG) – (n = 30) was conducted. Into the control group (CG) – (n = 30) were included the first- and second-time bearing women without fetal myoma with full-time pregnancy and the pelvic presentation. Statistical processing of the results was performed using the Microsoft Office Excel 2017 software. Results and Discussion. The analysis of the presented data shows that among pregnant women with pelvic prevalence of fetuses on the background of uterine fibroids, more frequent cases are registered: clinical manifestations of the threat of interruption of pregnancy MG – 26 (86.7 %), CG – 9 (30 %) and pre-eclampsia MG – 8 (26.7 %), CG – 3 (10 %) (p < 0.05). Raising the risk of complications of pregnancy and the expected birth of the uterine myoma requires pre-planning for the most part the operational method of delivery of MG – 19 (63.3 %). Exception, in the absence of other contraindications, there may be women with single myomatous nodes in sizes up to 5 cm – 11 (36.7 %). Only the extension of the cesarean section requires only pregnant women with uterine myoma 7 (36.8 %), and most of these interventions occur during precarious surgical delivery 4 (20 %). Conclusion. Consequently, the presented data indicate the expediency and validity of taking into account the presence of uterine myoma at BP in order to develop an optimal obstetric tactic for the delivery of such patients in order to improve their pregnancy outcomes.

The Effects of After School Math Clubs on County Benchmark Scores

The purpose of this study was to determine whether after school math clubs would have an effect on Anne Arundel County Public Schools math benchmark scores. The measurement tool used was the AACPS Math Benchmark 1 and Benchmark 2 assessments. This study involved collecting data after Benchmark 1 and 2 were given to students in the test group. After analyzing the data, students were placed in the math club. The math club met once a week during which time students reviewed previous skills taught. The results showed no significant differences in benchmark scores after participating in an After School Math Club.
Kardiyak resenkronizasyon tedavisinde ekokardiyografinin rolü Role of echocardiography in the management of cardiac resynchronization

Numerous randomized clinical trials demonstrated the beneficial effects of cardiac resynchronization therapy (CRT) in the treatment of moderate to severe heart failure. However, response to CRT may vary significantly among individuals. 30-50 % of patients still do not respond to CRT in clinical practice. Specific techniques in order to determine the patients who will benefit from CRT are required. Among these techniques, echocardiography has emerged over recent years as the technique of choice to identify patients for the presence of mechanical dyssynchrony before CRT implantation. Despite its usefulness in detecting mechanical dyssynchrony, this issue is still a matter of debate. Although its routine use in patient selection is not recommended today, it seems echocardiography will be the method of choice in patient selection to CRT for the next years.
Transfert de technologie : les dimensions oubliées. A partir de l'étude et la comparaison de trois cas au sein de PME béninoises.

L'enjeu de la maitrise des transferts technologiques ne cesse de croitre pour les entreprises qui se trouvent confrontees a une mondialisation de plus en plus importante des echanges. Paradoxalement, alors que les sciences de gestion proposent de nouvelles sources de comprehension des transferts technologiques, celles-ci ont ete tres peu utilisees dans la litterature specialisee. L'objectif de cette recherche est en consequence de revisiter les concepts entourant les transferts technologiques en proposant une « grounded theory ». Dans ce cadre, les apports de la these sont de plusieurs ordres :
Especiació en plantes de muntanya: una aproximació biosistemàtica als papers de la hibridació i l’aïllament geogràfic.

La hibridacio es un fenomen molt frequent en plantes, pero els hibrids solen ser esterils. Existeixen barreres reproductives que dificulten l’intercanvi genetic entre especies, pero, no obstant, aquest acaba tenint lloc. Aixo genera moltes preguntes, com ara les seguents. Quines solen ser aquestes barreres i, sobretot, com aconsegueixen ser superades? Quin paper hi te l’aillament geografic? En zones de muntanya, s’ha proposat la vicariancia com a proces clau en la diversificacio de les plantes, pero realment es la vicariancia el proces que contribueix majoritariament a la diversificacio de plantes en els habitats de muntanya? L’objectiu d’aquesta tesi es trobar respostes a aquestes preguntes i per aixo tractarem les diferents questions en diversos grups de plantes que s’hi ajusten en base a estudis previs. Els grans temes que abordem amb aquesta idea son els seguents: i) processos d’especiacio per hibridacio en un grup citogeneticament complex d’especies de muntanya, la seccio Triplinervium del genere Saxifraga (Saxifragaceae), ii) hibrids F1 i el seu tractament taxonomic: caracteritzacio i tipificacio de Jacobaea ×mirabilis (Asteraceae), iii) hibridacio i introgressio en endemismes de muntanya, una possible amenaca per a la conservacio? Estudi sobre les dues especies del genere Rhaponticum (Asteraceae) dels Alps: R. heleniifolium i R. scariosum, i iv) diversificacio del genere Artemisia (Asteraceae) a l’alta muntanya europea: quins son els factors que hi han contribuit de manera mes decisiva? Els resultats obtinguts en les diferents publicacions d’aquesta tesi mostren que les principals fonts de diversificacio en plantes son l’intercanvi genetic (hibridacio i introgressio) i les mutacions cromosomiques (com guanys, perdues o reestructuracions de bracos cromosomics, que poden acabar derivant en casos de disploidia). Per contra, l’aillament geografic per se no genera diversificacio, pero permet la fixacio de noves combinacions cromosomiques per processos de coll d’ampolla, o be facilita o impedeix el contacte entre diferents especies, es a dir, determina quines especies poden acabar hibridant. En els casos que hem estudiat, i a diferencia del que se sol postular, s’ha pogut constatar, a mes, que la poliploidia no es la font mes comuna d’origen de noves especies, sino que l’especiacio sol tenir lloc en el mateix nivell de ploidia, ja sigui despres d’una hibridacio (especiacio hibrida homoploide o hibridacio introgressiva) o be per canvi del nombre cromosomic basic (disploidia).

Nivolumab ± ipilimumab in pts with advanced (adv)/metastatic chemotherapy-refractory (CTx-R) gastric (G), esophageal (E), or gastroesophageal junction (GEJ) cancer: CheckMate 032 study.

4014Background: In the phase 3 ONO-12 study, 3rd- or later-line nivolumab (N) monotherapy prolonged OS vs placebo in Asian pts with adv G/GEJ cancer (median OS, 5.3 vs 4.1 mo; HR, 0.63; P < 0.0001; ASCO-GI 2017, Kang YK et al. J Clin Oncol. 2017;35 (suppl 4S) [abstract 2]). The phase 1/2 CheckMate 032 study showed favorable clinical activity of N ± ipilimumab (I) in Western pts with adv CTx-R G/E/GEJ cancer (NCT01928394). We report updated long-term follow-up data of G/E/GEJ pts in CheckMate 032. Methods: Pts received N 3 mg/kg Q2W (N3), N 1 mg/kg + I 3 mg/kg Q3W (N1+I3), or N 3 mg/kg + I 1 mg/kg Q3W (N3+I1). Primary endpoint was ORR. Secondary endpoints included DOR, OS, PFS, and safety. Efficacy in pts by PD-L1 status was assessed. Results: 160 heavily pretreated pts (79% had ≥ 2 prior Tx) were enrolled (N3, n = 59; N1+I3, n = 49; N3+I1, n = 52); 24% had PD-L1+ (≥ 1%) tumors. ORR was 12% in N3, 24% in N1+I3, and 8% in N3+I1. In pts with PD-L1 ≥ 1%, ORR was 19% (3/16) in N3, 40% (4/10) in N1+I3, and 23% .
SDFS: A software‐defined file system for multitenant cloud storage

Performance isolation is highly desirable in cloud platforms where the virtual disks of virtual machines are simply large files on the shared and networked storage servers. However, existing isolation techniques cannot deal with the implications of the file system used by the networked storage servers, such that underlying resource usage is unpredictable (eg, the delayed write‐back mechanism could postpone writes, and the journaling mechanism could amplify writes). The lack of visibility on underlying resource usage leads to the predicament of being unable to meet isolation goals. In this paper, we present a software‐defined file system (SDFS) that exploits the underlying file system to allocate resources at per‐image‐file granularity and provide tenants with guaranteed throughput. The SDFS comprises two components: control plane and data plane. At the control plane, we provide a set of system calls to document tenant performance requirements into the metadata of image files. At the data plane, we construct a file‐based scheduler to manage memory and disk resources according to the tenant performance requirements. The SDFS design does not require a modification to guest operating systems, hypervisors, or file server protocols. Through a prototype implementation, we demonstrate that the SDFS can meet isolation goals and increase resource utilization with negligible overhead.
Accurate attenuation correction in PET without accurate transmission measurements

In this study the authors use the consistency conditions of the Radon transform to aid attenuation correction in PET. The conditions are used both for estimating the boundary of a uniform attenuation distribution (without any transmission measurements) and for correcting for patient motion between the transmission and emission acquisitions. The results show that, for a uniform elliptical attenuation distribution, the image reconstructed with an attenuation distribution estimated using the consistency conditions is almost indistinguishable from an image reconstructed using the true attenuation coefficient map. The method is shown to be fairly tolerant to the effects of photon counting statistics and to small non-uniformities in the attenuation distribution (such as skull attenuation). The results also show that the consistency conditions may be useful in correcting for patient motion. The method is shown to accurately compensate for shifts in two dimensions using both simulated and experimental data.
The Internet Goes to College: How Students Are Living in the Future with Today's Technology.

Summary of Findings College students are early adopters and heavy users of the Internet College students are heavy users of the Internet compared to the general population. Use of the Internet is a part of college students’ daily routine, in part because they have grown up with computers. It is integrated into their daily communication habits and has become a technology as ordinary as the telephone or television. One-fifth (20%) of today’s college students began using computers between the ages of 5 and 8. By the time they were 16 to 18 years old all of today’s current college students had begun using computers – and the Internet was a commonplace in the world in which they lived. Eighty-six percent of college students have gone online, compared with 59% of the general population. College students are frequently looking for email, with 72% checking email at least once a day. About half (49%) first began using the Internet in college; half (47%) first began using it at home before they arrived at college. The great majority (85%) of college students own their own computer, and two-thirds (66%) use at least two email addresses. Seventy-eight percent of college Internet users say that at one time or another they have gone online just to browse for fun, compared to 64% of all Internet users. College Internet users are twice as likely to have ever downloaded music files when compared to all Internet users: 60% of college Internet users have done so compared to 28% of the overall population. College Internet users are twice as likely to use instant messaging on any given day compared to the average Internet user. On a typical day, 26% of college students use IM; 12% of other Internet users are using IM on an average day.
Tratamento contra a raiva humana: um pouco de sua histária

Trata-se de uma revisao historica sobre o tratamento utilizado contra a raiva, desde a antiguidade ate o momento atual. Pretende-se fazer uma analogia entre o conceito de causa predominante na epoca, com o tipo de tratamento preconizado. Os gregos antigos tinham a deusa Artemisa como sanadora da raiva e ja utilizavam a cauterizacao da ferida. Os povos do seculo I conheciam a infecciosidade na saliva de caes raivosos, chamando esse material de veneno ("virus" en latin). Na Idade Media, com um conceito magico e religioso da saude, o grande protetor era Sao Humberto. Com o renascimento surgem novamente muitos experimentos e avancos no conhecimento da doenca, que deram as bases para importantes achados. Nessa epoca predominava a teoria miasmatica e de contagio. Pasteur foi um grande opositor da espontaneidade da raiva. No final do seculo XIX, com os descobrimentos microbianos, Pasteur realizou a grande revolucao cientifica em relacao ao tratamento contra a raiva, que e a vacina. Essa atualmente pode ser de tipo nervoso ou nao, variando tambem o numero de doses recomendadas. Desenvolveram-se muitos estudos sobre vacinas, entretanto a mais utilizada na America Latina e a de tipo Fuenzalida e Palacios e a recomendada atualmente pela OMS e a de cultivo celular.
Original article Impact of cardiac resynchronisation therapy on adaptation of circulatory and respiratory systems to exercise assessed by cardiopulmonary exercise test in patients with chronic heart failure

Background: Cardiac resynchronisation therapy (CRT) has become a valuable therapeutic tool in patients with advanced chronic heart failure (CHF). The search for optimal methods for the assessment of CRT efficacy is still underway. Aim: To evaluate the impact of implantation of CRT devices in patients with CHF on adaptation of circulatory and respiratory systems to maximal exercise assessed by cardiopulmonary exercise tests (CPX) and 6-minute walking tests (6MWT). Methods: We investigated 27 patients (22 males, 5 females, 61.2±9.1 years) with a CRT device implanted due to advanced CHF, which resulted from ischaemic or dilated cardiomyopathy. All patients before implantation underwent echocardiography, CPX with expired gas analysis and 6MWT. Investigations were repeated at 3-6 months after CRT implantation. In CPX we evaluated peak oxygen uptake (peak VO 2 ), oxygen pulse, maximal minute ventilation-carbon dioxide production (VE/VCO 2 max), and its slope (VE/VCO 2 slope) and VE/VO 2 slope, VO 2 in anaerobic threshold (AT), and cardiac and respiratory reserve. In 6MWT we evaluated walking distance and heart rate and blood pressure response to exercise. Results: We noted statistically higher mean peak VO 2 after CRT implantation in the studied group: 11.34±3.38 vs. 14.56±3.99 ml/kg/min (p 2 : 1.00±0.43 vs. 1.43±0.67 l/min (p=0.004). The O 2 pulse rose from 9.65±3.39 to 13.23±5.43 ml/beat (p=0.015). We also observed a significant reduction of VE/VCO 2 slope from 42.34±13.35 before CRT to 34.77±6.04 after CRT (p=0.0196) and a significant decrease of VE/VO 2 slope from 41.32 ±15.46 to 34.01±6.27 (p=0.037). VE/VCO 2 max fell from 58.02±15.86 to 50.1±13.14 (p=0.009). Patients estimated their dyspnoea on the Borg scale at peak exercise at 4.75±0.75 points before CRT and at 3.67±1.15 points (p=0.002) after CRT. Patients could walk a longer distance during 6MWT than before CRT (367±154.9 vs. 231.1±170.3 m, p Conclusions: Cardiac resynchronisation therapy improves exercise tolerance measured by means of CPX and 6MWT, improves respiratory system efficiency and restores its adaptive mechanisms during exercise in patients with advanced CHF. Better exercise adaptation after CRT may be objectively measured with CPX parameters, and corelates with improvement of clinical symptoms. CPX seems to be a very helpful tool in assessing the results of CRT.
Quantum-evolutionary algorithms: a SW-HW approach

In this paper a HW/SW platform for the implementation of an optimizer based on a evolutionary algorithm, called quantum-inspired evolutionary algorithm (QEA), is introduced. It is based on the concept and principles of quantum computing, such as quantum bit and superposition of states, whose features are briefly described. The hardware implementation of the QEA using a FPGA board is therefore described together with the use of a customable software fitness in order to solve general purpose problems. HW-SW connections are provided by a PCI interface. Final aim is to build a flexible object able to optimize the choices of some sensible parameters in a dynamic system quickly, with particular attention on industrial and automotive applications.
Ressources scientifiques, culturelles et humaines de l'africanisme en Belgique: perspectives sur un patrimoine d'outre-mer et sa mise en valeur

L'A. presente ici quelques unes des composantes du patrimoine culturel africain de la Belgique, en considerant le terme « patrimoine » dans son sens economique, soit un ensemble de biens transmissibles par heritage . Il comprend donc un capital fixe, donnees scientifiques, livres, objets d'art, etc. et divers centres d'accumulation du capital fixe (musees, archives, bibliotheques, laboratoires, etc.). Quelques reperes sont utilises pour evoquer les particularites de l'investissement humain, culturel, economique de la Belgique en Afrique : Comment cet effort se situe-t-il par rapport a celui qui a ete consenti par le pays pour l'ensemble du monde extra-europeen ? Quelles sont les dynamiques de cet investissement, celles qui le soutiennent ou celles qui, au contraire, l'affaiblissent ? L'Africanisme belge subit une fragilite, commun a tous les heritages coloniaux, qu'il faudra consolider a tous prix
Data-driven process decomposition for circuit synthesis

This paper presents a new method for decomposing a high-level program description of a circuit into a collection of small modules in the same program notation. The modules are simple enough to be immediately implemented as transistor networks. The method consists of two main steps: the description is first put into Dynamic Single Assignment form in which each variable is assigned at most once in each execution; secondly, the DSA program is projected on different sets of variables and channels to produce each module. The decomposed system is semantically equivalent to the original one under the assumption of slack elasticity: the communicating channels between the modules can have an arbitrary slack (buffer length). In some cases, the decomposition produces modules that are too small and have to be grouped together. Unlike all other methods for circuit synthesis from high-level programs, this method is not syntax-directed. Rather it is based on data dependency among the different variables and channels of the system. The method is general: it is not restricted to asynchronous implementation.
