High performance subgraph mining in molecular compounds
Structured data represented in the form of graphs arises in
several fields of the science and the growing amount of available data makes distributed graph mining techniques particularly relevant. In this paper, we present a distributed approach to the frequent subgraph mining
problem to discover interesting patterns in molecular compounds. The problem is characterized by a highly irregular search tree, whereby no reliable workload prediction is available. We describe the three main
aspects of the proposed distributed algorithm, namely a dynamic partitioning of the search space, a distribution process based on a peer-to-peer communication framework, and a novel receiver-initiated, load balancing
algorithm. The effectiveness of the distributed method has been evaluated on the well-known National Cancer Institute’s HIV-screening dataset, where the approach attains close-to linear speedup in a network

Post-Radical-Prostatectomy Urinary Incontinence: The Management of Concomitant Bladder Neck Contracture
Urinary incontinence postradical prostatectomy is a common problem which adversely affects quality of life. Concomitant bladder neck contracture in the setting of postprostatectomy incontinence represents a challenging clinical problem. Postprostatectomy bladder neck contracture is frequently recurrent and makes surgical management of incontinence difficult. The aetiology of bladder neck contracture and what constitutes the optimum management strategy are controversial. Here we review the literature and also present our approach

Esthésioneuroblastome nasosinusien: Nouvelles modalités thérapeutiques
Introduction : L’esthésioneuroblastome est une tumeur maligne rare des cavités nasosinusiennes. La chirurgie par voie externe et la radiothérapie ont été le traitement de référence. L’utilisation ces dernières années de la chirurgie endoscopique endonasale et de la chimiothérapie parait prometteuse.Observations : Nous présentons deux cas cliniques de patients traités pour esthésioneuroblastome nasosinusien : Le premier par une chirurgie endoscopique endonasale et une radiothérapie, le second par une chimio-radiothérapie. L’évolution a été favorable respectivement à 39 mois et à 49 mois.Discussion : A travers une revue de la littérature, nous discuterons les différentes modalités thérapeutiques de cette tumeur.Mots clés : esthésioneuroblastome, sinus, traitement
ANALISIS KEMAMPUAN SISWA DALAM MENYELESAIKAN SOAL HIGH ORDER THINKING SKILLS PADA MATERI STATISTIKA

Penelitian ini menggunakan deskriptif kuantitatif dan kualitatif. Subjek dalam penelitian ini adalah siswa kelas VIII-1 SMP Negeri 2 Langsa yang berjumlah 15 siswa. Objek dalam penelitian ini adalah kemampuan siswa dalam menyelesaikan soal High Order Thinking Skills (HOTS). Dari Hasil penelitian menunjukkan persentase rata-rata kemampuan HOTS siswa di bagian menganalisis (analyze) sudah di kriteria cukup yaitu 58,88%, dan pada bagian mengevaluasi (evaluate) masih di kriteria cukup yaitu, 41,67%, begitu juga pada bagian mencipta (create) masih di kriteria lemah yaitu, 35,18%. faktor yang menyebabkan siswa keliru dalam menyelesaikan soal high order thinking meliputi: belum pernah menyelesaikan soal berbasis HOTS berdasarkan hasil tes dan wawancara, kurangnya pemahaman siswa terhadap soal, kurang teliti dalam proses pengerjaan soal, serta tidak maksimal selama proses pembelajaran yang berlangsung
Threshold Verification Technique for Network Intrusion Detection System
Internet has played a vital role in this modern world, the possibilities and
opportunities offered are limitless. Despite all the hype, Internet services
are liable to intrusion attack that could tamper the confidentiality and
integrity of important information. An attack started with gathering the
information of the attack target, this gathering of information activity can be
done as either fast or slow attack. The defensive measure network administrator
can take to overcome this liability is by introducing Intrusion Detection
Systems (IDSs) in their network. IDS have the capabilities to analyze the
network traffic and recognize incoming and on-going intrusion. Unfortunately
the combination of both modules in real time network traffic slowed down the
detection process. In real time network, early detection of fast attack can
prevent any further attack and reduce the unauthorized access on the targeted
machine. The suitable set of feature selection and the correct threshold value,
add an extra advantage for IDS to detect anomalies in the network. Therefore
this paper discusses a new technique for selecting static threshold value from
a minimum standard features in detecting fast attack from the victim
perspective. In order to increase the confidence of the threshold value the
result is verified using Statistical Process Control (SPC). The implementation
of this approach shows that the threshold selected is suitable for identifying
the fast attack in real time.Comment: 8 Pages, International Journal of Computer Science and Information

Mapping Contemporary Islamic Jurisprudence of Muḥammad Saʻīd Al-‘ashmāwī and Muḥammad Shaḥrūr
Muḥammad Saʻīd Al-‘Ashmāwī and Muḥammad Shaḥrūr are well known as contemporary Muslim thinkers. This article tries to map their contemporary ideas on Islamic jurisprudence. The main data of this research taken mainly from the works both of Al-‘Ashmāwī and Shaḥrūr. In particular, the paper tries to analyze Al-‘Ashmāwī‘s ideas on sharia, politics, hijab, marriage and divorce. On the other hand, the ideas of Shahrour on al-Qur\u27an, Sunnah and Fiqh, the theory of borders, pluralism, the commandment, inheritance, hijab, marriage, divorce, dowry, politics, and imamate are also critizised. After analyzing their lives and their ideas on Islamic jurisprudence, the paper found that their social, educational and practical backgrounds have affected their intellectual formations and ideas. Ashmawi is encouraged by diligence and enlightenment and is believed to be enlightened. Shahrour, however, takes a new approach in order to create the ḥudūd theory as a new way. As well as their intellectual background, Ashmawi has a good queen in Arabic, English and French as well as religion, Sharia, jurisprudence and theology. Shahrour is a good queen in Arabic, English, Russian, philosophy, philology and historical language
Determining and mapping of vegetation using GIS and phytosociological approach in Mount Tahan, Malaysia.
The study on lowland tropical forest plants is complicated by the extreme species diversity, very complex plant
mosaic and time constraints. These impediments however do not occur in mountain forest, where habitat
diversity is clearly distinguished by small homogenous plants types. Plant association and composition study
were presented in this work from two locations of Mount Tahan, Malaysia the relatively untrampled and the
trampled site. In each site, plant species number, vegetation cover, plant height, and species cover and frequency
in untrampled and trampled areas were counted or measured. The analysis included a field survey following the
relevance method of Braun-Blanquet and mapping using a GIS. The study focused on altitudinal distribution of
specific plants communities located between 1900 m and 2140 m altitude. The data from field survey were
mapped and analyzed in GIS. The phytosociological classification revealed that untrampled areas in Botak and
Puncak sites were high in species more diversified communities compared to the trampled areas. The results
showed that Leptospermum flavescens was the dominant species most in both sites (Botak and Puncak), with
48%, specifically at the untrampled site. The abundance class and sociability value are also high for this species
with score 4.5 out of 5, respectively. A total number of trees in the area probably play an important role in
quantifying the species richness and diversity parameters. From the study it can be concluded that GIS technique
useful in developing a tree mapping system and creating a geo-database for spatial analysis. Further studies are
recommended to integrate more data into the system for better evaluation
