Here, we report a rare case of a 23-year-old term parturient with Eisenmenger syndrome due to Taussig-Bing anomaly presenting with gestational hypertension, oligohydramnios, and intrauterine growth retardation posted for elective cesarean section. Preoperatively, echocardiography of the patient was suggestive of double-outlet right ventricle (DORV) with large sub-pulmonic ventricular septal def...

We derive an effective action for Dirac fermions coupled to O(3) non-linear σ-model (NLσM) through the Yukawa-type interaction. The nonperturbative (global) quantum anomaly of this model results in a Hopf term for the effective NLσM. We obtain this term using the “embedding” of the CP1 model into the CPM generalization of the model which makes the quantum anomaly perturbative. This perturbative...

introduction the avan cu-fe skarn is located at the southern margin of qaradagh batholith, about 60 km north of tabriz. the skarn-type metasomatic alteration is the result of qaradagh batholith intrusion into the upper cretaceous impure carbonates. the studied area belongs to the central iranian structural zone. in regional scale, the studied area is a part of the zangezour mineralization zone ...

The satellite record since 1979 shows downward trends in Arctic sea ice extent in all months, which are smallest in winter and largest in September. Previous studies have linked changes in winter atmospheric circulation, anomalously cold extremes and large snowfalls in mid-latitudes to rapid decline of Arctic sea ice in the preceding autumn. Using observational analyses, we show that the winter...

We describe and analyze a simple and effective stochastic sub-gradient descent algorithm for solving the optimization problem cast by Support Vector Machines (SVM). We prove that the number of iterations required to obtain a solution of accuracy is Õ(1/ ), where each iteration operates on a single training example. In contrast, previous analyses of stochastic gradient descent methods for SVMs r...

Long-term production planning design is a major step in mine planning, because it determines the economic outcome of a project. Also long-term planes act as a guide for medium and short-term production scheduling. Because there are a large number of blocks within the ultimate pit limit, the pit can be divided into a series of sub-pits commonly called push backs, cut backs or phases. These push ...

• Skarn-type mineralization of the Cuonadong Sn-W-Be polymetallic deposit occurred at ca. 15 Ma. Skarn-hosted scheelite can be divided into an older type 1 and a younger 2 scheelite. The ore-forming fluid was exsolved from Miocene leucogranite. Geochemically isotopically, modified by intense fluid-rock interaction during skarnization greisenization. is first rare-metal with extraordinary metall...

Sandstone-hosted roll-front uranium ore deposits originate when U(VI) dissolved in groundwater is reduced and precipitated as insoluble U(IV) minerals. Groundwater redox geochemistry, aqueous complexation, and solute migration are important in leaching uranium from source rocks and transporting it in low concentrations to a chemical redox interface where it is deposited in an ore zone typically...

Sub-pixel matching is one of the key components for image registration and image fusion. Ideally, image matching should allow for offsets in the target image, and for scaling and rotation. Offsets allow for sub-pixel shifts in the two images, while scaling is necessary when matching images from different sensors or images taken from different distances using the same camera. Rotation allows for...
