The control of the A/B comonomer distribution over individual chains targeting block and/or gradient monomer distributions is essential to macroscopic properties resulting copolymers. Matrix-based kinetic Monte Carlo simulations allow compare each chain a representative copolymer sample with desired (mathematical) composition, as defined by inclusion probabilities (PA/B) taking B-functionalizat...

Background: Hysteroscopy is currently the gold-standard procedure in evaluation of uterine cavity and treatment intrauterine lesions as it minimally invasive has high diagnostic efficiency. According to previous observations, many patients are afraid procedures performed under general anesthesia. They also that, according them, may be associated with pain. To address this issue, study, levels s...

BACKGROUND We assessed the applicability, acceptability and cost implications of introducing the manual vacuum aspiration (MVA) technique with local anaesthesia for fully conscious first-trimester termination of pregnancy within our service and for our population. SETTING The outpatient setting of a Pregnancy Advisory Service within a NHS Sexual Health Service. METHODS Self-administered mis...

AN article in this issue reports that cervical dilation is more rapid in women receiving combined spinal–epidural analgesia (CSE) compared with epidural analgesia for the treatment of labor pain. A similar observation was reported recently in another article in ANESTHESIOLOGY that found more rapid cervical dilation with lumbar sympathetic block than with epidural analgesia. Neither study reveal...

Image denoising by block matching and threedimensionaltransform filtering (BM3D) is a two steps state-ofthe-art algorithm that uses the redundancy of similar blocks innoisy image for removing noise. Similar blocks which can havesome overlap are found by a block matching method and groupedto make 3-D blocks for 3-D transform filtering. In this paper wepropose a new block grouping algorithm in th...

the statistical analysis of spatial data is usually done under gaussian assumption for the underlying random field model. when this assumption is not satisfied, block bootstrap methods can be used to analyze spatial data. one of the crucial problems in this setting is specifying the block sizes. in this paper, we present asymptotic optimal block size for separate block bootstrap to estimate the...

normal 0 false false false en-us x-none ar-sa background: regional anesthesia is widely used to perform different surgical procedures including those performed on the extremities . in this study, the anesthetic effects of adding intrathecal neostigmine or magnesium sulphate to bupivacaine in patients under lower extremities surgeries were assessed. materials and methods: in this double-blind ra...
