In this paper, the segmentation of ultrasonic images using self-organizing neural networks (NN) is investigated. A modification of Learning Vector Quantizer (called L2 LVQ) is proposed so that the weight vectors of the output neurons correspond to the L2 mean instead of the sample arithmetic mean of the input observations. The convergence in the mean and in the mean square of the proposed varia...

During cellular invasion, human papillomavirus type 16 (HPV16) must transfer its viral genome (vDNA) across the endosomal membrane prior to its accumulation at nuclear PML bodies for the establishment of infection. After cellular uptake, the capsid likely undergoes pH-dependent disassembly within the endo-/lysosomal compartment, thereby exposing hidden domains in L2 that facilitate membrane pen...

This paper reports on an adaptation and validation study of Self-regulating Capacity in Vocabulary Learning Scale (Tseng et al. 2006) in a Japanese EFL setting. The piloting phase revealed that factor structures were different from those in the original study. The main study, including a self-reported measure of procrastination to explore the convergent evidence of the construct validity, sugge...

This study identifies the level of L2 motivational self-system (L2MSS) consisting Ideal Self, Ought-to and Learning Experience, application deep surface learning strategies on high school students regarding gender grades. The is designed in both correlation descriptive comparative models. research sample composed 202 students. Two questionnaires are used collection data: Motivational Self Syste...

Encapsidation of papillomavirus DNA involves DNA-protein and protein-protein interactions. We sought to define the role of each human papillomavirus (HPV) capsid protein in HPV DNA encapsidation. HPV16 major (L1) and minor (L2) capsid proteins purified from recombinant vaccinia virus-infected cells were compared for their ability to bind nucleic acids. L2 protein, but not L1 protein, could bind...

the objectives of this study were (a) to examine the writing performance of l2 learners on the level-specific tasks based on common european framework of reference (cefr) and (b) to investigate whether there was any difference between the students' self-assessed level of writing and the writing level reported by the raters. this study was conducted with 138 iranian students at ba and ma levels ...

This study aimed at investigating the possibility of improving EFL learners’ self-efficacy by implementing a metacognitive strategies instruction program. The participants were 53 female EFL learners who were divided into two experimental and control groups. The experimental group received an eight-week treatment on metacognitive strategies through descriptions, modeling, and practice. At the b...
