Hundreds of experiments over the last decade on the retrieval of OCR documents performed by the Information Science Research Institute have shown that OCR errors do not significantly affect retrievability. We extend those results to show that in the case of proximity searching, the removal of running headers and footers from OCR text will not improve retrievability for such searches.

Let X be an arrangement of n algebraic sets Xi in d-space, where the Xi are either parametrized or zero-sets of dimension 0 ≤ mi ≤ d − 1. We study a number of decompositions of d-space into connected regions in which the distance-squared function to X has certain invariances. Each region is contained in a single connected component of the complement of the bifurcation set B of the family of dis...

In order to retrieve best documents for finding answers, we developed a robust proximity search engine. It efficiently finds relevant passages. In addition, our search engine has two disjunction operators: or and or2. The former works just like addition, whereas the latter works just like logical disjunction. The operator or2 is used to introduce synonyms and antonyms of a query term. The searc...

In this paper, we propose a novel ICP variant that uses a histogram in conjunction with multiple closest points to detect the overlap area between range images geing registered. Tentative correspondences sharing similar distances are normally all within, or all outside, the overlap area. Thus, the overlap area can be detected in a bin by bin batch manner using a histogram. Using multiple closes...

Introduction: Foreign bodies in the esophagus are considered to be a life-threatening condition in adults and children because of esophageal perforation, chemical pneumonitis, airway obstruction, and development of a fistula, leading to high morbidity and mortality with this condition. Most cases present with immediate symptoms. However, in rare cases, the foreign body can migrate within the t...

Neurotrophin-3 (NT-3) is required for proprioceptive neuron survival. Deletion of the proapoptotic gene Bax in NT-3 knockout mice rescues these neurons and allows for examination of their axon growth in the absence of NT-3 signaling. TrkC-positive peripheral and central axons from dorsal root ganglia follow proper trajectories and arrive in close proximity to their targets but fail to innervate...

We present the management of a case of Type II dens invaginatus in a mandibular premolar with a large invagination in the coronal third of the root on mesial aspect of the crown in proximity of cementoenamel junction significantly compromising the strength of the crown structure. We describe in detail the various measures taken to assess the internal tooth structure destruction and enhance the ...

Acid or base concentrations can be determined by performing an acid-base titration with coulometrically generated OHor H+ ions at a noble metal actuator electrode in close proximity to the pH-sensitive gate of an ISFET. It is shown, both theoretically and experimentally, that the relation between the acid or base concentration and the time needed to reach the equivalence point in the resulting ...

The present study describes a case of endodontic sealer (AH Plus) penetration within and along the mandibular canal from the periapical zone of a lower second molar after endodontic treatment. The clinical manifestations comprised anesthesia of the left side of the lower lip, paresthesia and anesthesia of the gums in the third quadrant, and paresthesia and anesthesia of the left mental nerve, a...

Pain Physician Vol. 9, No. 3, 2006 To the Editor: We consistently obtain similar clinical outcomes using pulsed radiofrequency (PRF) applications to those reported by Rozen and Parvez (1). In agreement, our clinic has been successfully treating post inguinal herniorrhaphy pain for 10 years using PRF applications to the dorsal root ganglia. Thus, we thank the authors for their report. We do note...
