The search task of Luck, Hillyard, Mangun and Gazzaniga (1989) was optimised to test for the presence of a bilateral field advantage in the visual search capabilities of normal subjects. The modified design used geometrically regular arrays of 2, 4 or 8 items restricted to hemifields delineated by the vertical or horizontal meridian; the target, if present, appeared at one of two fixed position...

introduction: tuberculous otitis media (tom) is an uncommon, insidious, and frequently misdiagnosed form of tuberculosis (tb). in particular, tom is usually secondary to direct transmission from adjacent organs, while the primary form has been rarely reported. the main aim of treatment is to start the patient on an antitubercular regime and early surgical intervention to decompress the facial n...

purpose : to describe a case of bilateral squamous cell carcinoma in right nasal and left temporal conjunctiva, simulating bilateral pterygium case report : a reddish fibrovascular pterygium-like lesion was observed in the nasal side of bulbar conjunctiva on the right eye and temporal conjunctiva of the left eye. medical examination not revealed any coexistent malignancy elsewhere excisional bi...

â â â  â  â  abstract â  this paper aims to identify key challenges facing iran and south korea in their bilateral trade and investment relations. in particular, it is concerned with the policy implications which can be useful for policy makers and business people of both countries. for this purpose, we review and analyze the recent developments of the iranian economy and bilateral trade and in...

introduction: noradrenergic cells in lc participate in the process of cortical activation and behavioral arousal. the evidence suggests that locus ceoruleus (lc) plays an important role in the sleep-wake cycle. the aim of this study was stereological estimation of cavity caused by lesion and assessment of sleep stages after bilateral lesion of the lc. materials and methods: male wistar rats wei...

When a toddler starts to walk without support, gait kinematics and EMG activity differ from those of older children and the body displays considerable oscillations due to poor equilibrium. Postural instability clearly affects motor patterns in adults, but does instability explain why toddlers walk with a different gait? Here we addressed this question by comparing kinematics and EMGs in toddler...

This paper develops a new instrumental-variable (IV) approach to estimate the effects of different exchange rate regimes on bilateral outcomes. The basic idea is that the characteristics of the exchange rate regime between two countries (exchange rate variability, fixed or float, autonomous or common currencies) are partially related to the independent decisions of these countries to peg —expli...

I present a strategic model of a bilateral oligopoly with asymmetric information to examine (i) the validity of the conjecture of price-taking behavior in such markets as the number of agents becomes large and (ii) the effect of the rate that individual information precision decreases with increased number of agents on convergence to price-taking and efficiency. I show that with downstream comp...

This study compares lung dose distributions for two common techniques of total body photon irradiation (TBI) at extended source-to-surface distance calculated with, and without, tissue density correction (TDC). Lung dose correction factors as a function of lateral thorax separation are approximated for bilateral opposed TBI (supine), similar to those published for anteroposterior-posteroanterio...

The aim of this investigation was the analysis of the variability within the internal and external ophthalmic artery in the chinchilla (Chinchilla laniger, Molina). The head vasculature of 65 individuals was analysed, with particular emphasis on the internal ophthalmic artery originating from the central and rostral part of the cerebral arterial circle. Head blood vessels were filled with acryl...
