Four-dimensional realistic modeling of pancreatic organogenesis.
Organogenesis, the process by which organs develop from individual precursor stem cells, requires that the precursor cells proliferate, differentiate, and aggregate to form a functioning structure. This process progresses through changes in 4 dimensions: time and 3 dimensions of space-4D. Experimental analysis of organogenesis, by its nature, cuts the 4D developmental process into static, 2D hi...
متن کاملLung Deformation Estimation and Four-Dimensional CT Lung Reconstruction
Four-dimensional (4D) computed tomography (CT) image acquisition is a useful technique in radiation treatment planning and interventional radiology in that it can account for respiratory motion of lungs. Current 4D lung reconstruction techniques have limitations in either spatial or temporal resolution. In addition, most of these techniques rely on auxiliary surrogates to relate the time of CT ...
متن کاملLung Deformation Estimation and Four-dimensional CT Lung Reconstruction1
Rationale and Objectives. Four-dimensional (4D) computed tomography (CT) can be used in radiation treatment planning to account for respiratory motion. Current 4D CT techniques have limitations in either spatial or temporal resolution. In addition, most of these techniques rely on auxiliary surrogates to relate the time of the CT scan to the patient’s respiratory phase. We propose a 4D CT metho...

صنعت بیمه به دلیل عرضه محصول منحصر بفرد، در طبقه بندی مالی به عنوان یک صنعت با هزینه های بالا شناخته شده است. رفتار هزینه ها یک معیار مهم برای برای تعیین قدرت مالی شرکت بیمه استو این موضوع به ویژه برای بیمه گذاران و سرمایه گذاران از اهمیت اساسی برخوردار است. این مطالعه هزینه های شرکت های بیمه را در قالب سریهای زمانی پنلی انجام میدهد. تحلیل پنلی کمک برای درک رفتار نا متعارف، پیش بینی هزینه ها، و...

We investigate a 4D analog of 2D WZW theory. The theory turns out to have surprising niteness properties and an innnite-dimensional current algebra symmetry. Some correlation functions are determined by this symmetry. One way to deene the theory systematically proceeds by the quantization of moduli spaces of holomorphic vector bundles over algebraic surfaces. We outline how one can deene vertex...
