DVB-T interference cancellation in radar signal processing

In this paper, a novel filter for cancellation of DVB-T interference in low-frequency synthetic aperture radar systems is presented. The filter relies on using the pilots in the DVB-T signal to estimate the communications channel between the broadcast antenna and the flying radar system. Then, by decoding and re-coding the interference signal, it can be subtracted from the combined radar and TV signal. Simulation results indicate good performance in relevant signal-to-interference ratios.
Toward standardizing spatial analysis for optical topography

Optical topography is an emerging neuroimaging technique for the noninvasive monitoring of human cerebral hemodynamics. Its relatively more compact, flexible, and affordable setup allows bedside monitoring of patients and infants in clinical situations, and of healthy subjects in their real-life environments. However, optical topography poses a technical obstacle in that it measures cortical activities from the head surface without anatomical information of the brain, which is essential to identify the source of the monitored brain activity. It also poses difficulty in comparing data with that from other neuroimaging techniques, which use a standard template for presenting functional brain analyses. To cope with this problem, we have developed spatial analysis methods that allow stand-alone optical topography data to be presented in standard brain spaces. These methods are automatic and do not require the subjects' MR images, which may be too expensive or difficult to acquire under certain clinical or experimental restrictions.
Dispersal within a spatially structured population of lesser kestrels: the role of spatial isolation and conspecific attraction

Summary 1 Factors governing dispersal rates have seldom been examined in spatially structured populations of vertebrates. We gathered information during 8 years on transfer rates between subpopulations in a spatially structured, growing population of colonial lesser kestrels Falco naumanni, and analysed the contribution of several variables related to spatial isolation and characteristics of both subpopulation of origin and destination on probabilities of dispersal. 2 Lesser kestrels were highly philopatric to their subpopulations, but first-breeders dispersed more often than adults (26% vs. 4%, n= 1706) because adults were reluctant to move from familiar areas. Frequency of subpopulation change was higher in females than in males (first-recruiters: 30% vs. 22%, n= 987; adults 5% vs. 1%, n= 719), according to their different breeding roles. However, all populational factors had an equal effect on individuals of different sex and dispersal status. 3 Movement rates decreased with inter-subpopulation distance – indicating that travelling to distant subpopulations may impose costs in terms of breeding prospects – and with the number of subpopulations, which increased during our study period. 4 Conspecific attraction strongly influenced the probability of dispersal: it was relatively higher in largely populated subpopulations, and individuals of large subpopulations were reluctant to change to others. These results were neither influenced by the size and breeding density of the subpopulations nor by habitat quality in terms of food availability or risk of predation, as indicated by breeding success of kestrels at each subpopulation. The number of conspecifics could be used by the kestrels as a cue of patch quality in terms of settlement options, and large subpopulations could be more easily detected by prospecting birds. 5 Our study highlights the fact that several assumptions of theoretical metapopulation modelling are often not fulfilled in nature. Both theoretical models and management strategies on spatially structured populations or metapopulations should thus consider the number, population size, and spatial distribution of local populations, as well as their relationships with the dispersal ability of the species.
Pensée privée et communication sociale

Le fonctionnement cognitif d'un individu et le fonctionnement de la communication sociale sont deux phenomenes soumis a des contraintes assez differentes. Il n'est donc pas evident d'imaginer un parallelisme etroit entre ces deux processus. Pourtant la question de la parente entre la pensee et le langage a ete maintes fois abordee : pensons-nous avec des mots, la pensee est-elle un langage interiorise, le langage precede-t-il la pensee chez l'enfant, etc. ? Je propose aussi d'aborder cette question, mais sous un angle original. La caracteristique du langage qui est retenue ici n'est pas la faculte d'agencer des mots pour produire des phrases qui evoquent une signification. Si l'on regarde le langage au niveau pragmatique, en retenant seulement de la faculte langagiere le fait qu'elle permet d'enchainer des arguments pertinents, alors force est de constater, dans le detail, une forte similitude entre le deroulement du flux de la pensee et celui de la communication sociale par excellence : la conversation. En d'autres termes, je suggere que l'enchainement des pensees obeit aux contraintes de pertinence. Si l'on accepte de considerer une telle hypothese, alors on doit envisager la possibilite que la structure de la pensee privee, constitutive de l'intelligence des individus humains, soit phylogenetiquement une consequence des exigences de la communication sociale.
Ground moving target tracking of PAMIR detections with a Gaussian Mixture-PHD filter

This paper presents the application of the Gaussian Mixture Probability Hypothesis Density (GM-PHD) filter to ground moving target tracking for observations by an airborne scanning radar. An overview of modifications to the standard GM-PHD algorithm and the adaptations for ground moving target tracking is given. Experimental results for the tracking of ground truth targets and of targets of opportunity based on data acquired by the experimental radar system PAMIR are shown.
Vers une étude spectroscopique de la transition d'Anderson

Ce memoire resume les travaux d'une these portant sur le transport et la localisation d'Anderson d'ondes de matiere ultra-froide en milieu desordonne. C'est un travail experimental visant a l'etude de la transition d'Anderson separant les etats d'energie d'une particule quantique placee dans un potentiel desordonne selon deux phases : des etats localises, et des etats diffusifs.Dans un premier temps, on rappellera les concepts fondamentaux permettant de comprendre les effets de localisation des ondes, et notamment leur interpretation en terme d'interferences. Ensuite, on donnera une description globale du dispositif experimental permettant de preparer les nuages d'atomes ultra-froids servant de source d'ondes quantiques de matiere, et de generer la figure de tavelures optique (speckle en anglais) jouant le role de potentiel desordonne pour les atomes.A l'issue de ce travail introductif, les notions de localisation introduites precedemment seront appliquees au transport d'atomes froids dans un speckle. Un bref etat de l'art des experiences d'atomes froids portant sur la transition d'Anderson permettra de dessiner les limites en terme de controle de l'energie des etats peuples par les atomes. Ces limitations permettront alors de motiver la mise en place d'une nouvelle methode experimentale dite "spectroscopique" permettant un controle complet par un operateur exterieur de l'energie des atomes places le desordre.Le concept de fonction spectrale sera alors presente comme outil fondamental permettant de caracteriser les etats d'energie et de calibrer la fiabilite en energie de la methode spectroscopique. Enfin, des resultats experimentaux portant sur la mesure de fonctions spectrales par cette nouvelle methode spectroscopique viendront attester qu'il serait effectivement possible d'etudier la transition d'Anderson avec une resolution en energie bien superieure aux experiences precedentes.
Aging and Sense of Control

Three groups representing different phases of the developmental lifecycle—12 senior citizens, 67 young adults, and 14 healthy middle-aged normal adults—were assessed using a multidimensional control inventory. Senior citizens had a healthy over-all sense of control comparable to those of the other two groups and a significantly lower (healthier) negative sense of control. They also were significantly more likely to endorse acceptance as a way of addressing areas of concern and to complement self as a source of control with a sense of control coming from others (including God, belief in a higher power).
De novo assembly, characterization and annotation for the transcriptome of Sarcocheilichthys sinensis

The Chinese lake gudgeon Sarcocheilichthys sinensis is a small cyprinid fish with great aquaculture potential both for its edible and ornamental values. Nevertheless, available genomic and transcriptomic information for this fish is extremely deficient. In this study, a normalized cDNA library was constructed using 13 mixed tissues of an adult male S. sinensis, and was sequenced by the Illumina HiSeq2500 platform. De novo assembly was performed using 38,911,511 obtained clean reads, and a total of 147,282 unigenes with an average length of 900 bp were finally achieved. 96.2% of these unigenes were annotated in 9 public databases, and 16 segments of growth-related genes were identified for future studies. In addition, 28,493 unigenes were assigned to 61 subcategories of Gene Ontology (GO), and 10,483 unigenes were assigned to 25 categories of Cluster of Orthologous Group (COG). Moreover, 14,943 unigenes were classified into 225 pathways of the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. A total of 30,666 microsatellites were detected from 17,627 unigenes with an average distribution density of 1:2405 bp. This transcriptome data set will be valuable for researches on discovery, expression and evolution on genes of interest. Meanwhile, the identified microsatellites would be useful tools for genetic and genomic studies in S. sinensis.
Time and Space in Digital Game Storytelling

The design and representation of time and space are important in any narrative form. Not surprisingly there is an extensive literature on specific considerations of space or time in game design. However, there is less attention to more systematic analyses that examine both of these key factors--including their dynamic interrelationship within game storytelling. This paper adapts critical frameworks of narrative space and narrative time drawn from other media and demonstrates their application in the understanding of game narratives. In order to do this we incorporate fundamental concepts from the field of game studies to build a game-specific framework for analyzing the design of narrative time and narrative space. The paper applies this framework against a case analysis in order to demonstrate its operation and utility. This process grounds the understanding of game narrative space and narrative time in broader traditions of narrative discourse and analysis.
Artroplastía total cementada de rodilla: comparación entre el uso o no de isquemia en el resultado postoperatorio inmediato

Comparar el resultado postoperatorio inmediato en el paciente sometido a artroplastia total cementada de rodilla con y sin el uso de isquemia. Estudio observacional, transversal, retrospectivo, analitico y unicentrico. 180 pacientes operados de artroplastia total cementada de rodilla: 120 sin isquemia, 60 con isquemia, de 2011 a 2014, edad promedio 70 anos con DE ± 7 anos, se comparara el sangrado operatorio, diferencial de hemoglobina y dolor como criterios de resultado postoperatorio inmediato. Se excluyeron pacientes de clinica de dolor, manejo con anticoagulantes, coagulopatia previa, patologia siquiatrica, insuficientes renales o con intolerancia a AINEs. En artroplastia total cementada de rodilla sin isquemia se presenta mejor control del dolor (p = 0.026). El diferencial de hemoglobina y sangrado operatorio es menor cuando esta asociado al uso de isquemia (p = .008). Se requirio transfusion sanguinea en 32.8%, sin establecer una relacion entre el uso o exclusion de isquemia con relevancia estadistica (p = 0.301). El dolor referido mas comun se encuentra entre 0 y 3 de EVA correspondiente a dolor leve en 62.2% de los casos. El diferencial de hemoglobina promedio se reporta en 3.7 con desviacion estandar de ± 1.3 en un rango de 0 a 7.4. Existe menor dolor postoperatorio en el paciente al que no se aplica isquemia durante el procedimiento quirurgico; hay menor sangrado y diferencial de hemoglobina con el uso de isquemia; sin embargo, esto no representa estadisticamente una diferencia en la necesidad de transfusion sanguinea. Se recomienda utilizar con cautela la isquemia y su uso queda a eleccion del cirujano
Analysis of CYP2E1 polymorphism for the determination of genetic susceptibility to gastric cancer in Koreans

Background: Interindividual genetic differences in susceptibility to chemical carcinogens are among the most important host factors in human cancer. The present study was undertaken to reveal the association between the polymorphism of CYP2E1 (CYP2E1/PstI and CYP2E1/DraI) with genetic susceptibility to gastric cancer development in Koreans.
Cell cooperation in antibody induction. The susceptibility of helper cells to specific lethal radioactive antigen

Irradiated mice were reconstituted with syngeneic spleen cells from mice immunized with 2,4‐Dinitrophenyl(DNP)‐ovalbumin or Maia squinado hemocyanin (MSH) and challenged with DNP‐MSH. In this hapten‐carrier system MSH primed cells showed the expected helper activity for an anti‐DNP response. As previously shown for another system by Mitchison and Raff, the helper activity of MSH‐primed cells could be attributed to thymus‐derived (T) lymphocytes since it was suppressed by anti‐Θ serum and complement.
Usefulness of Spoligotyping To Discriminate IS6110Low-Copy-Number Mycobacterium tuberculosis Complex Strains Cultured in Denmark

ABSTRACT Mycobacterium tuberculosis complex strains cultured in Denmark have been analyzed by IS6110 restriction fragment length polymorphism (RFLP) on a routine basis from 1992 and onwards. Due to the influx of immigrants with tuberculosis, the number of strains harboring only one to five copies of IS6110 has increased steadily. Since the discriminatory power of IS6110 fingerprinting for such strains is poor, we have performed additional genotyping of all low-copy-number strains by the recently described PCR-based method known as spoligotyping. A total of 311 clinical strains were typed: 14 Mycobacterium bovisBCG, 48 M. bovis, and 249 M. tuberculosisstrains. Spoligotyping correctly differentiated M. bovisand M. bovis BCG from M. tuberculosis strains, but it did not differentiate M. bovis from M. bovis BCG. All M. bovis BCG strains exhibited identical spoligotype patterns. The discriminatory power of spoligotyping of low-copy-number M. tuberculosis strains was higher than that of IS6110 fingerprinting. Based on RFLP typing solely, 83% of the low-copy-number M. tuberculosis strains were found to form part of a cluster, and 75% were found to form a cluster on the basis of spoligotyping. When the two techniques were combined, the amount of clustering decreased to 55%. The combination of these two techniques might be valuable in studying the epidemiology of M. tuberculosis strains harboring few copies of the IS6110 element.
Nontraded asset valuation with portfolio constraints: a binomial approach

We provide a simple binomial framework to value American-style derivatives subject to trading restrictions. The optimal investment of liquid wealth is solved simultaneously with the early exercise decision of the non-traded derivative. No-short-sales constraints on the underlying asset manifest themselves in the form of an implicit dividend yield in the risk neutralized process for the underlying asset. One consequence is that American call options may be optimally exercised prior to maturity even when the underlying asset pays no dividends. Applications to executive compensation options are presented. We also analyze non-traded payoffs based on a price that is imperfectly correlated with the price of a traded asset. Cet article developpe un modele binomial d'evaluation des titres derives americains en presence de contraintes d'investissement. Les politiques optimales d'investissement et d'exercice du titre derive non-marchande sont resolues de maniere simultanee . La contrainte d'absence de ventes a decouvert se manifeste sous forme d'un dividende implicite portant sur le processus neutre au risque de l'actif sous-jacent. Une des consequences est l'optimalite possible de l'exercice avant l'expiration du contrat meme lorsque l'actif sous-jacent ne paye pas de dividendes. Une application a l'evaluation des options de compensation des cadres d'entreprises est presentee. Nous etudions egalement l'evaluation de titres bases sur un prix qui est imparfaitement correle avec le prix d'un actif transige.
Risk factors for late cervical lymph node metastases in patients with stage I or II carcinoma of the tongue

Many histopathologic parameters in squamous cell carcinoma of the tongue have been identified as predictive factors for cervical lymph metastasis. However, predictive factors for occult cervical lymph node metastases and the criterion for elective therapy remain inconclusive. This study analyzed the clinicopathologic factors associated with late cervical lymph node metastases in patients with carcinoma of the tongue.

Site-directed mutagenesis of human vasoactive intestinal peptide receptor subtypes VIP1 and VIP2: evidence for difference in the structure-function relationship.

Vasoactive intestinal peptide (VIP1 and VIP2) receptors belong to the new class II subfamily of G protein-coupled receptors. We investigated here human VIP1 and VIP2 receptors by mutating in their extracellular domains all amino acid residues that are conserved in VIP receptors but are different in other members of their subfamily. They are present in 1) the N-terminal domain, i.e., E36, I43, S64, D132 and F138 in the VIP1 receptor and E24, I31, S53, D116 and F122 in the VIP2 receptor; 2) the second extracellular loop, i.e., T288 and S292 in the VIP1 receptor and T274 and S278 in the VIP2 receptor. These residues were changed to alanine (A), and cDNAs were transfected into Cos cells. For the VIP1 receptor, no specific 125I-VIP binding could be detected in cells transfected with the E36A mutant, whereas other mutants exhibited Kd values similar to that of the wild-type receptor, with the exception of S64A, for which a 3-fold increase of Kd was observed. For the VIP2 receptor, no specific 125I-VIP binding could be observed with the E24A mutant, whereas other mutants exhibited dissociation constants similar to that of the wild-type receptor, with the exception of I31A and T274A mutants, for which a 11- and 5-fold increase of Kd was observed, respectively. cAMP production experiments provided evidence that the E36A VIP1 receptor and the E24A VIP2 receptor mutants mediated almost no response upon VIP exposure. For the I31A and T274A mutants of the VIP2 receptor and the S64A mutant of the VIP1 receptor, the EC50 values of VIP for stimulating cAMP production were increased 35, 8 and 3 times as compared with that observed for the wild-type receptor, respectively. Immunofluorescence studies indicated that all mutants were normally expressed by Cos cells. These data provide the first evidence for differences in the structure-function relationship of VIP1 and VIP2 receptors.
Survival and years of life lost in different age cohorts of patients with multiple myeloma.

PURPOSE To assess the impact of age on outcome and to analyze the projected years of life lost in patients with multiple myeloma. PATIENTS AND METHODS Ten thousand five hundred forty-nine patients were evaluated; 6,996 patients were treated with conventional chemotherapy, and 3,553 patients were treated with high-dose therapy with autologous stem-cell transplantation. RESULTS Mean observed and relative overall survival times in the entire cohort were 3.7 and 3.9 years, respectively. Observed survival decreased steadily from 6.4 years in patients younger than age 50 years to 2.5 years in patients > or = age 80 years. A similar decrease was noted for relative survival. Higher age correlated significantly with higher International Staging System (ISS) stage. Relative excess risk of death differed significantly between 10-year age cohorts beginning from age 40 years (P < .001 for age 50 to 59 v age 40 to 49, P < .001 for age 60 to 69 v age 50 to 59, P < .001 for age 70 to 79 v age 60 to 69, and P = .009 for age > or = 80 v 70 to 79). The average years of life lost per patient was 16.8 years in the entire patient cohort and decreased steadily from 36.1 years in patients younger than 40 years old to 4.6 years in patients > or = age 80 years. CONCLUSION Age is associated with higher ISS stage and is an important risk factor for early mortality. Survival declined continuously by each decade from age 50 to age > or = 80 from more than 6 to less than 3 years. The average of years of life lost in patients with myeloma is higher than in many other cancers and amounts to more than 30 years in patients younger than 40 years old but decreases to less than 5 years in patients age 80 years or older.
