Filter feature selection is one of effective methods for dimensionality reduction by removing irrelevant features from feature set. This paper focuses on two main problems of filter feature selection which are the feature score computation and the imbalance in the feature selection performance between categories. We propose a novel filter feature selection method, named ExFCFS, to comprehensively resolve these problems. We experiment on related filter feature selection methods with two benchmark datasets Reuters-21578 dataset and Ohsumed dataset. The experimental results show the effectiveness of our solutions in terms of both Micro-F1 measure and Macro-F1 measure. Keywords— bag-of-words vector, filter feature selection, document classification

La tecnica e, attualmente, ben codificata e il tasso di complicanze e molto basso (sei casi di infezione e un caso di pneumotorace su 950 interventi). II follow-up clinico a lungo termine dimostra una stabilita dei risultati morfologici rispetto al volume ottenuto a 3 o a 4 mesi postoperatori. La comparsa di focolai clinici di citosteatonecrosi e fortemente dipendente dall’operatore e si presenta all’inizio dell’esperienza. Sul piano radiologico, la valutazione mostra, il piu delle volte, degli aspetti di seni normali, con, talvolta, delle immagini di citosteatonecrosi, con, il piu delle volte, delle immagini di cisti oleose e, piu raramente, delle immagini di noduli di citosteatonecrosi o, ancora piu raramente, delle calcificazioni o delle cisti complesse. Secondo la nostra esperienza, queste immagini non si prestano a una confusione con la diagnosi di cancro per radiologi esperti nella diagnostica per immagini del seno. A causa del basso tasso di complicanze, dei risultati molto buoni ottenuti e dell’eccellente accettazione della tecnica da parte delle pazienti, questa tecnica ha completamente modificato le nostre indicazioni nella chirurgia plastica del seno. Nella ricostruzione mammaria, il lipomodellamento rappresenta il complemento ideale per la ricostruzione autologa con il lembo del gran dorsale. Il lipomodellamento puo essere applicato alle ricostruzioni mammarie mediante delle protesi, soprattutto in caso di sostituzione di protesi, e puo fornire il suo contributo nei ritocchi dopo trans rectus abdominis musculocutaneous (TRAM) flap o dopo deep inferior epigastric perforator (DIEP). Nel quadro della sindrome di Poland, il lipomodellamento sembra fornire un importante progresso e rivoluzionera, probabilmente, il trattamento dei casi gravi di sindrome di Poland. Il lipomodellamento apporta anche una nuova alternativa per il trattamento del pectus excavatum, dei seni tuberosi e delle asimmetrie mammarie con un’ipotrofia mammaria monolaterale.

The ideal characteristics are a thin layer of skin, a strong tendon component, combined with a reliable blood supply and minimal morbidity at the donor site. We present a reconstructive technique using a composite anterolateral thigh perforator free flap, meeting these criteria, for the treatment of rupture of Achilles tendon with cutaneous and tendon defect. A 34-year-old patient presenting a third rupture of his left Achilles tendon with 4cm composite defect was reconstructed with a contralateral anterolateral thigh perforator flap with part of the fasciae latae. The latter was raised by dissecting one intramuscular perforating artery from a descending branch of the lateral circumflex femoral artery. The postoperative observation period was one year. The functional outcome was determined by clinical scores (IKDC, OAK and...

The technique is now well established and the complication rate is very low. The risk of focal fat necrosis is around 3%. Oncological follow-up (now 14 years for the first patients) shows no increased risk of local recurrence or development of a new cancer. 30-40% of the injected fat is absorbed. Volume of the breast becomes stable in 3 to 4 months and remains definitive if the patient maintains constant weight. Because of very good results obtained and excellent acceptance of the procedure by the patients, this technique has completely modified our indications. In breast reconstruction, lipomodelling with autologous latissimus dorsi flap enables obtaining an entirely autologous breast in the majority of the patients. Analogically, lipomodelling can improve results of implant reconstructions, especially if the expander or the implan...

This paper proposes a new approach to recognize logical parts in Vietnamese legal documents based on a statistic machine learning method - Conditional Random Fields. Beside linguistic features such as word features, part of speech features, we use semantic features of logical parts such as trigger features and ontology features to improve the result of the annotation system. Experiments were conducted in a Vietnamese Business Law data set and obtained 78.12% at precision and 68.72% at recall measure. Compare to state-of-the-art systems, it improves the result for recognizing some logical parts

It causes rapidly developing skin necrosis and can occur after surgery, or after a nonspecific external stimulus. This condition is difficult to diagnose because it often mimics a fulminant infection. Clinical case We present a case of very significant local presentation of PG after placement of a venous access device. Fifteen days after placement, the patient developed extensive cutaneous ulcers and necrosis in the subclavicular area, which led to the misdiagnosis of infection. The device was removed and the patient was given antibiotics. Because there was no improvement following antibiotic treatment, combined with the worrying and extensive appearance of the skin and extremely intense pain, the diagnosis of PG was made. The patient was immediately treated with high-dose corticosteroids, resulting in rapid improvement of the lesions and relief of pain. Conclusion PG should be considere...

While the impact of these units has been well studied in English-Chinese CLIR, it has not been considered in English-Vietnamese CLIR. Therefore, in this paper, we examine how different translation units contribute to the English-Vietnamese CLIR performance.

The key factor of this system is the ability of indexing documents in several aspects: not only on the whole text but also on logical structures and ontologies of Vietnamese legal documents. There are two important phases in the system; firstly, focusing on the recognition of the structure of Vietnamese legal text and the extraction of ontology of documents stored in the database of Vietnam Ministry of Justice; secondly, building an automated information retrieval system for the advanced search on demand of Vietnamese citizens. We study Vietnamese legal domain in both linguistic features and patterns of recognition. Experimental result on recognizing logical structures got of 64.37% on assumption annotation, 64.15% on provision annotation and 75.76% on sanction annotation in the F β=1 score on the pre-built corpus of Vietnamese Enterprise Law articles. We also evaluated the precision of classifying ontology concepts and got 86.4 % in result on testing sample set of Vietnamese legal ontology. The goal is that a search engine is proposed with indexed logical and semantic properties based on works of the first phase.

Les patientes ont été revues à 1 an postopératoire. Aucune complication n'a été retrouvée à type d'infection locale, d'hémorragie, de rançon cicatricielle pathologique. Nous avons eu 1 souffrance cutanée précoce en regard des fasciotomies avec indication de traitement médical par cicatrisation dirigée. Conclusion.-Les transferts graisseux au niveau du sein améliorent la qualité trophique des tissus et apportent le volume souhaité sur mesure. Dans notre expérience clinique, les fasciotomies percutanées permettent de libérer les tissus fibreux notamment sur terrain irradié et sur les seins tubéreux, de diminuer la résorption graisseuse à long terme, sans rançon cicatricielle avec des indications précises. Le bilan d'imagerie volumétrique est actuellement en cours pour évaluer le taux de résorption graisseuse dans le sein au long cours.

Trois patientes sur 24 (12,5 %) ont bénéficié d'un second temps opératoire pour corriger l'asymétrie mammaire résiduelle. Aucune complication majeure n'a été répertoriée. Le sérum postopératoire a été noté dans 48 % des cas d'endoprothèse. Toutes les patientes ont été satisfaites du résultat final. Conclusions.-Les asymétries mammaires sur PE peuvent être dans la majorité des cas corrigées de façon satisfaisante à l'aide d'une endoprothèse thoracique seule. Il s'agit d'une technique fiable, reproductible. Aucune complication majeure n'a été notée. Si il persiste une insuffisance de résultat la pose de prothèse mammaire en silicone uni-ou bilatérale dans un second temps reste toujours possible.

The most common surgical techniques performed for gluteal augmentation employ gluteal implants. However, the results can be frustrating. Liposuction is one of the most common surgical procedures in aesthetic surgery. This surgical procedure can provide some complications. Fat grafting is an effective and predictable way to remodel the buttocks. To get better results, it's important to understand gluteal compartments with a descriptive study. The aim of this study is to describe gluteal semiology for buttocks remodeling with fat grafting. We have described gluteal semiology with our review of literature. We have analyzed fat compartments of gluteal region: volume, links between every compartments, connections with major gluteal muscle and with the skin. We have also analyzed shape and volume of the buttocks. We have described 11 aesthetic subunits, the volume and the shape of the buttocks, and the skin laxity. We did an important literature review to understand the most important gluteal zones to improve for patients' satisfaction. Our gluteal semiology description is very useful to understand liposuction/lipoinjection of gluteal areas. Fat grafting may be a reliable technique, simple and safe procedure. Surgery for correction of the buttocks may involve more than projection and volume. However, these must be in a balanced proportion with the rest of the body.

Most recently, ''propeller'' perforator flaps allow each perforator vessels to become a flap donor site. Once the perforator of interest is identified by acoustic Doppler, the cutaneous or fascio-cutaneous island is designed and then customized according to the principle of ''perforasome''. So, the flap can be rotated such a propeller, up to 1808. Ideally the donor site is self-closing, otherwise it can be grafted at the same time. Through a skin necrosis secondary to a contrast medium extravasation of the cubital fossa in a 47-year-old man, we describe the use of propeller perforator flap based on a perforator of the radial collateral artery (RCAP). The perforator was identified preoperatively by acoustic Doppler then the flap was adapted bespoke to cover the loss of substance. Ultimately, the result was very satisfying. Well experienced for lower-extremity reconstruction, perforator-based propeller flap are still few reported for upper limb. It is likely that in the future, propeller flap supersede in many indication not only free flaps and locoregional flaps but also, leaving no room for uncertainties of the vascular network, the classic random flaps.
