Arcuate scotomas and occasionally severe peripheral constriction of the visual field are familiar sequelae of drusen of the optic disk. Loss of central vision with this disk anomaly is rare and its occurrence always demands additional investigations. It has been a long established rule that monocular blindness cannot be attributed to the progressive neurovascular complications of optic disk dru...

Congenital anomalies of the oesophagus were once thought to be relatively rare. Plass in 1919 reported one case and in an exhaustive review of the literature found 136 fully verified cases; he stated that there was some variation in the minor details of the anomaly, but the general picture was uniform -a blind upper pouch ending at a level between the lower border of the larynx and the tracheal...

A mimicry attack is an exploit in which basic behavioral objectives of a minimalist ’core’ attack are used to design multiple attacks achieving the same objective from the same application. Research in mimicry attacks is valuable in determining and eliminating detector weaknesses. In this work, we provide a process for evolving all components of a mimicry attack relative to the Stide (anomaly) ...

Zircon grains are reasonably ubiquitous in river banks and beach placers as detrital minerals, including along the ~1700 km long Indian east coast, from Odisha state to of Kerala. Zircons located eastern part Odisha, India, were studied using LA-ICP-MS order delineate their geochemical characteristics. Hf (mean = 11270 ppm) Y 1064 two most abundant trace elements found within zircon compared ot...

kajal kaolin deposit is located ~20 km northwest of hashtjin, ardebil province. field evidence and laboratory investigations show that the deposit is an alteration product of ignimbrites, tuffs, and trachy-andesites of eocene age. according to mineralogical data, the major rock-forming minerals include kaolinite, montmorillonite, polygorskite, orthoclase, zeolite (stilbite), quartz, and chalced...

Multivariate measurements taken at irregularly sampled locations are a common form of data, for example, in geochemical analysis soil. In practical considerations, predictions these unobserved great interest. For standard multivariate spatial prediction methods it is mandatory to not only model dependencies but also cross-dependencies which makes demanding task. Recently, blind source separatio...

Abstract This communication reports novel geochemical and geochronological data of granite from the southeastern part Bastar Craton, Central India. The studied samples are leucocratic in appearance composed quartz, K-feldspar, plagioclase feldspar, biotite decreasing order abundances. Apatite, sphene, zircon occur as accessory minerals. SiO2 Al2O3 content sample varies between 61 69 wt.% 13 15 ...

-This paper presents the design and development of a Geochemical Expert System prototype (GES) for analyzing solution-mineral interactions in nature. The emphasis is placed on expert system design and knowledge representation. One of the most challenging and research-intensive steps was the identification of the key geochemical characteristics that would enable the expert system to identify sal...

the area is located 20 km northwest of kashmar and about 4 km of kalateh taimour in khorasan razavi province. the study area is part of tertiary volcanic-plutonic belt north of daruneh fault and its situation in tectonic inliers between two important active faults, doruneh and taknar. volcanic rocks are mainly intermediate to acid pyroclastic type. they formed during early tertiary. the volcani...

the infomax algorithm is a popular method in blind source separation problem. in this article an extension of the infomax algorithm is proposed that is able to separate mixed signals with any sub- or super-gaussian distributions. this ability is the results of using two different nonlinear functions and new coefficients in the learning rule. in this paper we show how we can use the distribution...
