Linear and non-linear transceiver processing for MEVIO-FBMC systems

Filter Bank Multicarrier (FBMC) systems has drawn interest as an alternative to orthogonal frequency division multiplexing (OFDM), as FBMC offers higher spectral efficiency and less susceptibility to synchronization errors. One drawback in FBMC systems is the presence of inter-carrier-interference (ICI) and inter-symbol-interference (ISI), which degrades the system performance when operating under fading channels. In this work we consider the bit error rate (BER) performance of a multiple input multiple output (MIMO) FBMC system. We evaluate the performance of linear and non-linear transceiver processing techniques, which attempt to mitigate the effect of ICI and ISI in MIMO FBMC systems. Simulation results are presented to evaluate and compare the transceiver processing techniques discussed.
A reduction from efficient non-malleable extractors to low-error two-source extractors with arbitrary constant rate

We show a reduction from the existence of explicit t -non-malleable extractors with a small seed length, to the construction of explicit two-source extractors with small error for sources with arbitrarily small constant rate. Previously, such a reduction was known either when one source had entropy rate above half [Raz05] or for general entropy rates but only for large error [CZ16]. Asin previous reductions we start with the Chattopadhyay and Zuckerman approach [CZ16], where an extractor is applied on one source to create a table, and the second source is used to sample a sub-table. In previous work, a resilient function was applied on the sub-table and the use of resilient functions immediately implied large error. In this work we replace the resilient function with the parity function (that is not resilient). We prove correctness by showing that doing the sampling properly, the sample size can be made so small that it is smaller then the non-malleability parameter t of the ﬁrst extractor, which is enough for the correctness. The parameters we require from the non-malleable construction hold (quite comfortably) in a non-explicit construction, but currently it is not known how to explicitly construct such graphs. As a result we do not give an unconditional construction of an explicit low-error two-source extractor. However, the reduction shows a new connection between non-malleable and two-source extractors, and also shows resilient functions do not play a crucial role in the two-source construction framework suggested in [CZ16]. Furthermore, the reduction highlights a barrier in constructing non-malleable extractors, and reveals its importance. We hope this work would lead to further developments in explicit constructions of both non-malleable and two-source extractors.
On Consistency and Network Latency in Distributed Interactive Applications: A SurveyPart I

This paper is the first part of a two-part paper that documents a detailed survey of the research carried out on consistency and latency in distributed interactive applications (DIAs) in recent decades. Part I reviews the terminology associated with DIAs and offers definitions for consistency and latency. Related issues such as jitter and fidelity are also discussed. Furthermore, the various consistency maintenance mechanisms that researchers have used to improve consistency and reduce latency effects are considered. These mechanisms are grouped into one of three categories, namely time management, information management, and system architectural management. This paper presents the techniques associated with the time management category. Examples of such mechanisms include time warp, lock step synchronization, and predictive time management. The remaining two categories are presented in part II of the survey.
Chemotaxis by a CNS macrophage, the microglia

Microglia demonstrate many characteristics similar to those seen in monocytes and tissue‐specific macrophages, including phagocytosis, production of oxygen radicals, and growth factors and expression of MHC antigens. We have examined the ability of microglia, cultured from the cerebral cortices of neonatal rats, to demonstrate another important functional characteristic of monocytic‐derived cells, that is, chemotaxis. Our results show that cultured rat microglia demonstrate chemotaxis to complement dependent chemoattractants such as recombinant C5a, zymosan activated serum, and to rat serum as well as to transforming growth factor‐beta, a chemoattractant produced by platelets, Microglia fail to migrate to bacterial dependent chemoattractants such as the N‐formyl peptides. The failure to respond is not dependenton maturational state of the microglia. Treatment with DMSO or casein, agents known to induce morphological and functional changes in cultured microglia reminescent of a “resting” and an “activated” macrophage, respectively, do not alter the response to fMet‐Leu‐Phe. In addition, the chemotactic response to serum in DMSO or casein‐treated cells is the same as the response seen in untreated day 10 cultured microglia or untreated age‐matched controls. The ability of microglia to migrate in response to inflammatory mediators suggests that these cells can move to sites of injury, thereby enabling them to participate in an inflammatory response.
Enriched feather hydrogen isotope values for Wood Thrushes sampled in Georgia, USA, during the breeding season: implications for quantifying dispersal

We used an analysis of deuterium values (dD) of 151 Wood Thrush (Hylocichla mustelina (J.F. Gmelin, 1789)) feathers collected during the breeding season at the Piedmont National Wildlife Refuge in Georgia, USA, to determine fi- delity to the study site. We compared dD values in feathers of birds with known molt locations and birds with unknown molt locations. Mean feather value of dD was -24.8% (SD = 10.5%, range = -48.0% to -5.5%), and we were unable to determine a site-specific signature to assess fidelity of breeders within our sample. We used an information criterion ap- proach to evaluate multiple hypotheses to explain the high variation in dD, and the geographic location of sample sites within the study area was selected as the best model. Feather dD values were higher than expected from mean growing- season rainfall dD values predicted for our study site. We discuss possible explanations for the enriched dD values and postulate that heat stress during molt may have contributed to our results. We suggest that future stable isotope data collec- tion consider the potential for small-scale variation in feather dD values; information on diet gathered simultaneously with feather samples may be valuable for future studies.

Phenotypic evaluation of acapsular transposon mutants of Vibrio vulnificus

Translucent, avirulent spontaneous phase variants of Vibrio vulnificus MO6-24 reverted back to the original opaque, encapsulated phenotype under both in vivo and in vitro conditions. Two translucent, acapsular mutants, which did not show phase variation, were constructed by using the transposon Tn5 IS50L::phoA (TnphoA). Loss of capsule was accompanied by decreases in virulence, hydrophilicity, and serum resistance. The ability to utilize transferrin-bound iron for growth was lost in only one of the two unencapsulated mutants. Our data emphasize the apparent importance of capsule in the virulence of V. vulnificus and indicate that utilization of transferrin-bound iron is independent of encapsulation.

Segmentation par coupes de graphe avec a priori de forme Application à l'IRM cardiaque

Le contourage des ventricules cardiaques sur IRM est necessaire a la determination de la fonction contractile du coeur. Cette tâche est difficile, en particulier pour le ventricule droit (VD), due au flou aux frontieres des cavites, aux irregularites des intensites et a sa forme complexe et variable. Peu de travaux ont cependant ete realises afin de resoudre cette problematique de segmentation. Dans ce but, nous avons propose et developpe deux methodes de segmentation basees sur la methode des coupes de graphe (GC), a laquelle nous avons incorpore des a priori de forme. La premiere methode, semi-automatique, repose sur une carte d'a priori statistique creee a base d'Analyses en Composantes Principales et integree a la methode des GC binaires. La seconde, automatique, permet la segmentation d'un ensemble d'objets par GC multi-labels a partir d'un modele de forme probabiliste base sur le recalage et la fusion d'atlas. Ces methodes ont ete evaluees sur une base importante d'IRM cardiaques, composee de 48 patients. Une comparaison aux methodes de l'etat de l'art pour cette application a travers le challenge de segmentation du VD MICCAI'12, que nous avons organise, montre l'efficacite de nos methodes.
AUXIN RESPONSE FACTOR 17 Is Essential for Pollen Wall Pattern Formation in Arabidopsis 1 [ C ] [ W ] [ OA ]

In angiosperms, pollen wall pattern formation is determined by primexine deposition on the microspores. Here, we show that AUXIN RESPONSE FACTOR17 (ARF17) is essential for primexine formation and pollen development in Arabidopsis (Arabidopsis thaliana). The arf17mutant exhibited amale-sterile phenotype with normal vegetative growth. ARF17was expressed in microsporocytes and microgametophytes from meiosis to the bicellular microspore stage. Transmission electron microscopy analysis showed that primexine was absent in the arf17 mutant, which leads to pollen wall-patterning defects and pollen degradation. Callose deposition was also significantly reduced in the arf17 mutant, and the expression of CALLOSE SYNTHASE5 (CalS5), the major gene for callose biosynthesis, was approximately 10% that of the wild type. Chromatin immunoprecipitation and electrophoretic mobility shift assays showed that ARF17 can directly bind to the CalS5 promoter. As indicated by the expression of DR5-driven green fluorescent protein, which is an synthetic auxin response reporter, auxin signaling appeared to be specifically impaired in arf17 anthers. Taken together, our results suggest that ARF17 is essential for pollen wall patterning in Arabidopsis by modulating primexine formation at least partially through direct regulation of CalS5 gene expression.
Assessment of the Developmental Anatomy of the Japanese Quail (Coturnix Japonica) Using the Gizzard as a Growth Indicator

The study evaluated the relationship between body weight and gizzard development of quail birds from day-old to 12weeks. Biometrical dimensions and weight of the gizzard which are key determinants in measuring feed conversion and digestibility efficiency of the gastrointestinal tract (GIT) of avian species were considered. The experiment was started with sixty-five day-old quail birds that were subjected to the same condition with respect to housing, feed and water. Five of these birds were sacrificed on delivery at day-old and at regular interval weekly until the end of the twelfth week. The weight, length, width and thickness of the gizzards were measured. Data were presented as mean and standard deviation, inferentially analyzed using correlation coefficient, one-way analysis of variance and Duncan test. The average body and gizzard weight ranges from 5.82±0.27g to 161.0±5.97g and 0.25±0.05g to 4.77±0.22g respectively while the gizzard length, width and thickness ranges were 1.00±0.03cm to 2.54±0.02cm; 0.90±0.05cm to 1.87±0.12cm and 0.50±0.02cm to 1.42±0.08cm respectively. The pairwise correlation coefficient for the parameters were statistically significant (p<0.01). There was significant difference (p<0.01) in the body weight, gizzard weight, gizzard length, gizzard width and gizzard thickness across the age groups. Farmers should ensure proper feeding especially during the critical periods of the birds’ development as these periods are very important in their overall performance.
Partial trisomy of the short arm of chromosome 18 due to inversion duplication and direct duplication

We report one patient with a de novo inversion duplication 18 (ptercen) and two cases of direct tandem duplication 18 (ptercen), one due to maternal inheritance and the other arising as mosaicism of unknown origin. The duplications are demonstrated by high resolution banding. They were verified by in situ hybridization with a paint specific for chromosome 18 and with DNA probe LI.84 specific for the centromere region of chromosome 18. FISH with the genomic DNA probe pHRR68 specific for 18p11.32 revealed a subtle deletion concomitantly involved in the case of inversion duplication 18p. The patients exhibit slight developmental delay/moderate mental retardation and only a few dysmorphic features. The literature on trisomy 18p is reviewed and the present cases are compared to it.
Détection d'hypovigilance chez le conducteur par fusion d'informations physiologiques et vidéo

L'hypovigilance correspond a la transition entre la veille et le sommeil durant laquelle l'organisme voit ses facultes d'observation et d'analyse fortement reduites. Elle est responsable de nombreux accidents sur la route. Le but de cette these est de proposer un systeme de detection de cette phase accidentogene a partir de l'analyse conjointe de l'activite cerebrale (electroencephalogramme ou EEG) et d'une video du conducteur. Dans un premier temps, une methode non-supervisee de detection d'hypovigilance fonctionnant a l'aide d'un unique canal EEG a ete proposee. Cette methode, qui met en oeuvre differentes techniques de traitement du signal et de diagnostic, obtient de bonnes performances sur un ensemble de conducteurs, sans qu'il soit necessaire de regler de parametres. Dans un deuxieme temps, nous nous sommes interesses a la caracterisation des signes visuels de l'hypovigilance par une analyse video des clignements. Une comparaison entre l'approche video developpee et l'approche traditionnelle par electro-oculogramme (EOG) a permis d'etudier dans quelle mesure la video peut remplacer l'EOG pour la caracterisation des clignements. Elle a egalement permis de souligner la necessite d'utiliser d'une camera rapide (pouvant aller jusqu'a 200fps) pour caracteriser les clignements. Un algorithme de detection d'hypovigilance a partir de la caracterisation video des clignements a ainsi ete developpe. Pour finir, un algorithme de detection d'hypovigilance fusionnant, a l'aide de logique floue, les informations obtenues par les approches physiologique et video est presente. Toutes ces methodes ont ete testees et validees sur une base de donnees consequente de conduite en etat d'hypovigilance, la base de donnees ayant ete expertisee par un specialiste.
Differential effects of hypertension in the aetiology of major intracerebral haemorrhage subtypes

Hypertension, is more common in deep than in lobar ICH Knowledge of the pathophysiology and management of primary intracerebral haemorrhage (ICH) has increased substantially over recent years, and the article by Jackson and Sudlow in this issue (see p 1244) 1 makes a further important contribution to our understanding of this serious illness. In a meticulously conducted meta-analysis of observational studies with defined localisation of the ICH, they have shown that overall a history of hypertension was about twice as common in deep ICH as in lobar ICH. However, there was considerable heterogeneity across studies, and sensitivity analyses restricted to higher quality studies markedly attenuated the differential effect of this exposure (or outcome). Thus, apart from …
Quantitative study of local passive transfer of tuberculin sensitivity with peritoneal exudate cells in the guinea pig.

The peritoneal exudate cells of tuberculin sensitive guinea pigs, used in earlier surviving cell culture experiments, were shown to produce small but typical delayed reactions when mixed with antigen and injected into the skin of normal guinea pig recipients. Injection of the same mixtures intracorneally produced an opacity lasting 48 hr, not produced by injection of control mixtures. In newborn animals as recipients, local passive skin reactions could not be produced. By injecting multiple doses of antigen and cells into single (sometimes two) recipients and by measuring the volumes of the reactions as precisely as possible, we obtained characteristic dose response curves. High concentrations of tuberculin (1:20-1:5) inhibited the passive reactions in many of these experiments. Incubation of the cells with antigen before injection and incubation of the cells before addition of antigen failed to produce the release of inflammatory agents, of antibody, or of cells with increased reactivity. Suspensions of spleen cells failed to produce well defined transferred reactions. It is concluded that the transferred cells react directly with antigen at the injected site and that a volume increase of the transferred cells comparable to that seen in surviving cell culture, with or without actual cell multiplication, is sufficient to account for the size of the reactions observed in the absence of participation by the recipient's own cells.
Implementation of an interprofessional communication and collaboration intervention to improve care capacity for heart failure management in long-term care

ABSTRACT Heart failure affects up to 20% of nursing home residents and is associated with high morbidity, mortality, and transfers to acute care. A major barrier to heart failure management in nursing home settings is limited interprofessional communication. Guideline-based heart failure management programs in nursing homes can reduce hospitalisation rates, though sustainability is limited when interprofessional communication is not addressed. A pilot intervention, ‘Enhancing Knowledge and Interprofessional Care for Heart Failure’, was implemented on two units in two conveniently selected nursing homes to optimise interprofessional care processes amongst the care team. A core heart team was established, and participants received tailored education focused on heart failure management principles and communication processes, as well as weekly mentoring. Our previous work provided evidence for this intervention’s acceptability and implementation fidelity. This paper focuses on the preliminary impact of the intervention on staff heart failure knowledge, communication, and interprofessional collaboration. To determine the initial impact of the intervention on selected staff outcomes, we employed a qualitative design, using a social constructivist interpretive framework. Findings indicated a perceived increase in team engagement, interprofessional collaboration, communication, knowledge about heart failure, and improved clinical outcomes. Individual interviews with staff revealed innovative ways to enhance communication, supporting one another with knowledge and engagement in collaborative practices with residents and families. Engaging teams, through the establishment of core heart teams, was successful to develop interprofessional communication processes for heart failure management. Further steps to be undertaken include assessing the sustainability and effectiveness of this approach with a larger sample.
The Role of the Liver in Serum-induced Hypercoagulability

experiments, the BSP-containing saline was perfused after an initial 40-minute perfusion with saline alone. The BSP concentration was reduced to 10.6 2.7% 5 of the initial value at 10 minutes (50 minutes after the onset of saline perfusion). These studies indicate that the liver maintained its metabolic viability (as measured by BSP clearance) and cellular integrity (as measured by release of serum glutamic oxaloacetic transaminase activity) for the 40 minutes of perfusion.
