Two new species, Ooencyrtus alrake Hayat, sp. nov. and Syrphophagus wayanadensis Hayat, sp. nov. (Hymenoptera: Chalcidoidea: Encyrtidae), are described from material collected in Kerala State (India) from Trioza jambolanae Crawford (Hemiptera: Psylloidea: Triozidae), a leaf gall-inducer on species of Syzygium (Myrtaceae). Two species, Psyllaephagus garuga S. Singh and P. phacopteron S. Singh, b...

A fundamental problem in machine learning is identifying the most representative subset of features from which we can construct a predictive model for a classification task. This paper aims to present a validation study of dimensionality reduction effect on the classification accuracy of mammographic images. The studied dimensionality reduction methods were: locality-preserving projection (LPP)...

Lendometriose perineale correspond a la presence de tissu endometrial au niveau du perinee superficiel, le plus souvent sur une cicatrice depisiotomie ou dechirure obstetricale. Le diagnostic preoperatoire repose lIRMet sera confirme par analyse histologique pour excluretoute autre tumeur. traitement medical avec les analogues GnRH est inefficace. reste chirurgical et consiste en unelarge resec...

The zero-forcing (ZF) and minimum mean square error (MMSE) based detectors can approach optimal performance in the uplink of massive multiple-input multiple-output (MIMO) systems. However, they require inverting a matrix whose complexity is cubic relation to dimension. This lead high computational effort, especially MIMO To mitigate this, several iterative methods have been proposed literature....

INTRODUCTION It has long been known (e.g. Warkany & Schraffenberger, 1947; Wilson, 1949; Russell & Russell, 1954; Russell, 1957) that X-irradiation can phenocopy mutation and that in mice (Russell, 1950) there are sensitive periods during embryonic development for the production of these effects. It has also been known (Van Scott & Reinertson, 1957) that X-irradiation of adult mouse hair follic...

Les tumeurs cardiaques foetales sont rares, la plupart benignes dont les rhabdomyomes plus frequents , il est souvent de bon pronostic mais ils peuvent entrainer des complications graves, notamment arythmies, lanasarquefoetalvoir même mort foetal in utero . êtresoit unique ou multiple multiples associes a sclerose tubereuse Bourneville (STB) Nous rapportons un cas decouvert au cours grossesse...

La coexistence dun carcinome epidermoide de la langue et dune tuberculose ganglionnaire cervicale est un fait clinique rare. Nous rapportons le cas patiente age 55 ans, qui a beneficie hemiglossectomie pour avec curage cervical bilateral. Lexamen histopathologique definitif conclu une association au cancer langue, sans metastase ganglionnaire. Le pronostic depend du langue. Sa stadification cha...

Fibroadenomas are the most common tumors in women of childbearing age, especially young under age 30. The majority biopsied ACR4A lesions correspond to adenofibromas. Usually these solid, oval, well defined, with regular contours, lobulated (≥4 lobulations).We present case a 17-year-old girl, who has multiple fibroadenomas, about 36 lesions. fibroadenomas unique, however, can be observed 15-2...

La localisation vesicale de lendometriose est rare. On rapporte une observation chez femme 44 ans prise en charge au Centre Hospitalier Universitaire Ibn Rochd (CASABLANCA). Depuis un an, elle presentait des douleurs pelviennes, dysurie et hematurie macroscopiqueconcomitants aux menstruations. Les arguments cliniques echographiques avaient fait suspecter endometriose traitement chirurgical demb...
