INTRODUCTION Prostate cancer is usually diagnosed by transrectal ultrasound (TRUS) biopsy. Nevertheless, suspicious images are frequently not found. Imaging analysis studies aim to identify ultrasound patterns characteristic of apparently hidden conditions. MATERIAL AND METHODS We digitally recorded 288 TRUS ultrasound guided transrectal biopsies and extracted 3 static images from the punctur...

This study aims to evaluate the link between economic growth and consumer price index (CPI) in Japan for the period of 1980-2014. Initial series were adjusted for stationarity using the Augmented Dickey- Fuller (ADF) test for unit root followed by the application of Johansen Co-integration Test in order to examine the long-run relationship among the variables, while the causalities were evaluat...

In this article we present a model of realistic drawing accounting for visuomotor coordination, namely the strategies adopted to coordinate the processes of eye and hand movement generation, during the drawing task. Starting from some background assumptions suggested by eye-tracking human subjects, we formulate a Bayesian model of drawing activity. The resulting graphical model is shaped in the...

The search accuracy achieved in a PDF image-plus-hiddentext (PDF-IT) document depends upon the accuracy of the optical character recognition (OCR) process that produced the searchable hidden text layer. In many cases recognising words in a blurred area of a PDF page image may exceed the capabilities of an OCR engine. This paper describes a project to replace an inadequate hidden textual layer o...

This article challenges existing interpretations of Central Asia as a geographical entity. Adopting history technology approach to defining and analytically ‘constructing’ region, it scrutinizes the ways region has been materially created over years through four types large technical systems (infrastructures): waterways, railways, electricity grids natural gas pipelines. process, which is trace...

Web is title admittance today mainly relies on search engines. A large amount of data is hidden in the databases behind the search interfaces referred to as “Hidden web”, which needs to be indexed so in order to serve user’s query. In this paper database and data mining techniques are used for query interface integration (QII). The query interface must resemble the look and feel of local interf...

Recurrent neural networks (RNNs) have been successfully applied to various natural language processing (NLP) tasks and achieved better results than conventional methods. However, the lack of understanding of the mechanisms behind their effectiveness limits further improvements on their architectures. In this paper, we present a visual analytics method for understanding and comparing RNN models ...

I study the provision of incentives in a continuous time dynamic moral hazard model with hidden actions and hidden states. I consider a principal-agent model with linear production and exponential utility, whose explicit solution allows me to show how allocations are distorted for incentive reasons, and how access to hidden savings further alters allocations. I solve the model by applying a sto...

We extend previous research on digital filter structures and parameter sensitivity to the relationship between the nature of hidden-unit activation function, weight sensitivity and interdependence, and classification learning in neural networks. Weight sensitivity indicates the extent of variations in a network's output when reacting to small perturbations in its weights; whereas weight interde...
