We present a simple approximate algorithm to compute the Minimum Enclosing Ball (MEB) of training samples in high dimensional Euclidean space. We prove theoretically that the proposed algorithm converges to the optimum within any precision quickly. Compared to popular MEB algorithms, it has the competitive performances on both training time and accuracy. Besides, the proposed algorithm does not...
Improved Characterization of Forest Transmissivity Within the L-MEB Model Using Multisensor SAR Data
مأموریت اسموس (SMOS)، نخستین مأموریت ماهوارهای آژانس فضایی اروپا (ایسا) برای پایش جهانی رطوبت خاک، در سال 2009 آغاز شد. این ماهواره حامل اولین تابشسنج مایکروویو نوار-L است که دماهای درخشندگی چندزاویهای با پوشش جهانی را در سطح زمین برآورد می‌کند. هدف پژوهش حاضر ارزیابی دادههای دمای درخشندگی قطبش افقی (TBh) و قطبش قائم (TBv) محصولات قطبیده کامل چندزاویهای ماهواره اسمو...
Walker-Warburg syndrome (WWS) is an autosomal recessive developmental disorder characterized by congenital muscular dystrophy and complex brain and eye abnormalities. A similar combination of symptoms is presented by two other human diseases, muscle-eye-brain disease (MEB) and Fukuyama congenital muscular dystrophy (FCMD). Although the genes underlying FCMD (Fukutin) and MEB (POMGnT1) have been...
The Small Set Expansion Hypothesis (SSEH) is a conjecture which roughly states that it is NPhard to distinguish between a graph with a small set of vertices whose expansion is almost zero and one in which all small sets of vertices have expansion almost one. In this work, we prove conditional inapproximability results for the following graph problems based on this hypothesis: Maximum Edge Bicli...
We study optimization methods for source-initiated energyefficient broadcast in all-wireless networks. The minimum energy broadcast (MEB) problem in wireless networks proved to be NP-complete [1,4]. Past studies on MEB problem [1,2,5,8,9] focus on deterministic optimization to construct energy-efficient broadcast tree. In this paper, we present a probabilistic optimization approach, the Randomi...
Serum creatine kinase levels after succinylcholine in children with "muscle, eye and brain disease".
Four boys belonging to a group of children affected by a rare form of muscular dystrophy with eye and brain involvement, termed the "muscle, eye and brain disease" (MEB), were anaesthetized for various eye examinations and surgery. On some occasions succinylcholine was used during anaesthesia and the initially elevated serum creatine kinase (CK) values increased from a range of 122 to 1200 unit...
In the current opinion, we would like to study adhesion of DNA and RNA−amphiphile complexes to non–modified glasses, glasses containing phenylboronic acid (PBA) attached via 3– glycidoxypropyltrimethoxysilane (GPTMS) [(PBA–GPTMS–glasses)] and glasses containing grafted dimethyllacrylamide–acrylamide phenylboronic acid (DMAA–AAPBA) copolymer (DMAA–AAPBA– glasses). We prepared glasses modified wi...
We study the construction of the source-initiated (one-to-all) wireless broadcast tree to minimize the total required power for a given source node, a group of intended destination nodes and a given propagation constant, i.e., the power attenuation constant λ . The Minimum-Energy Broadcasting (MEB) problem has received much attention recently due to the two main challenges of mobile communicati...
