Let X be a semi-stable arithmetic surface over the spectrum S of the ring of integers in a number field K. We assume that the generic fiber XK is geometrically irreducible and has positive genus. Consider a line bundle L on X , which is non-negative on every vertical fiber and equipped with an admissible metric (in the sense of Arakelov [A]) of positive curvature. In [S] we have shown that any ...

We propose a multiscale extension of a well-known line segment detector, LSD. We show that its multiscale nature makes it much less susceptible to over-segmentation and more robust to low contrast and less sensitive to noise, while keeping the parameter-less advantage of LSD and still being fast. We also present here a dense gradient filter that disregards regions in which lines are likely to b...

We present a new analysis tool for cervical flexion-extension radiographs based on machine vision and computerized image processing. The method is based on semiautomatic image segmentation leading to detection of common landmarks such as the spinolaminar (SL) line or contour lines of the implanted anterior cervical plates. The technique allows for visualization of the local curvature of these l...

abstractthe purpose of this study was to assess organizational and personnel structure in iranian agriculture extension system (iaes). the research instrument was a structural questionnaire including close-ended questions which its validity and reliability was confirmed by using expert panel and cranach’s alpha test, respectively. the statistical population of this research included all public ...

PURPOSE To demonstrate the impact of inconsistent bite line positioning during pre and post lateral cervical radiographic examinations and to suggest certain additional imaging studies if the bite line cannot be consistently maintained. METHODS Radiographic measurements of relative flexion and extension in the atlantal-occipital (AO) and atlantal-axial (AA) joints were taken from neutral late...

We calculate the excursion and meander area distributions of the elastic Brownian motion by using the self adjoint extension of the Hamiltonian of the free quantum particle on the half line. We also give some comments on the area of the Brownian motion bridge on the real line with the origin removed. We will stress on the power of self adjoint extension to investigate different possible boundar...

Present study was conducted in the three provinces of Pakistan with the objectives to study the curricula relevancy with the participatory extension, supervision and administration and its practical applicability at the field level. For this extension agents of the selected provinces were selected purposively. Mail questionnaire were used as instruments for data collection form 227 respondents ...

BACKGROUND The anterior approach to the hip gained popularity for total hip arthroplasty in recent years. Distal extension of the anterior approach, sometimes needed intraoperatively, potentially endangers neurovascular structures to the quadriceps. The aim of this study was to determine the anatomical structures placed at risk by distal extension of the anterior approach to the hip. METHODS ...

R and Python are commonly used software languages for data analytics. Using these as the course introductory gives students practical skills applying statistical concepts to analysis. However, reliance upon command line is perceived by typical nontechnical student sufficiently esoteric that its use detracts from teaching of An package was developed based on successive feedback hundreds statisti...
