Recognition Algorithms for Structured Documents with Variable Content

The paper deals with a wide class of structured documents that cannot be described using one or several models based on associations between the document fields and geometric elements. A formal model of such documents is described that is based on the concept of a multiset. Examples of structured documents of this class are given and a technique for the construction of models of structured documents is proposed. This technique is illustrated using an implementation of an automated document management system. Implemented algorithms for detecting document fields are described, and implementation problems are discussed.__________Translated from Programmirovanie, Vol. 31, No. 4, 2005.Original Russian Text Copyright © 2005 by Slavin.     

Saving on energy resources in the oil and gas complex

Saving on fuel and energy resources and environmental protection are closely associated problems whose solution is drawing increasing attention all over the world. Despite the fact that enormous fuel and energy resources are concentrated in Russia: 1/3 of the proven world reserves of natural gas (approximately 48 trillion m³), 13% of the crude oil, 23% of the coal, and 14% of the uranium, their efficient utilization is a necessary condition for raising the country’s economy.

Hospital integrated lanes training: brigade-directed implementation of a medical lanes training program during annual training

The "lanes" concept of training was integrated into a medical site support mission of the 804th Medical Brigade, U.S. Army Reserve, during Annual Training, 1993 at Fort Drum, New York. This training, termed Hospital Integrated Lanes Training (HILT), included STX, FTX, patient play, and full use of Deployable Medical Systems equipment. The medical care of over 33,000 personnel participating in tactical annual training exercises was not interrupted during any concurrent phase of lanes training. Brigade operations planners developed an array of medical exercises that involved both moulaged and paper patient play. These exercises began prior to hospital set-up and continued for 24 hours a day throughout the tactical exercise. Injuries likely to be encountered during combat operations were inserted into the play singly and under a mass-casualty scenario. The standard of care for all injuries was determined with the Army Medical Department Center and School guidance. Prior coordination of brigade medical assets with external air and ground ambulance organizations broadened the scope of the training and facilitated effective use of command and control, communications, and equipment over a wide geographic area. Medical records were collected and evaluated at the conclusion of all exercises. After-action reviews were conducted by all medical units to assist in the planning of future HILT exercises. The HILT concept is a valuable tool for the complex training requirements of field medical units organized under medical Force 2000. The concept of integrated lanes training allows for the development and continuous improvement of individual and sectional skills for medical personnel and should be applied within all echelons of care.     

Epidemiological evidence for the impact of whole grains on health

Current dietary advice suggests consumers increase consumption of whole‐grain products because of their potential role in prevention of chronic disease. Whole grains are important sources of nutrients that are in short supply in our diet, including dietary fiber, resistant starch, trace minerals, certain vitamins, and other compounds of interest in disease prevention, including phytoestrogens and antioxidants. Despite dietary recommendations to increase intake of whole grains, little epidemiological evidence is available to support the physiological importance of whole‐grain intake. Most epidemiological studies focus on nutrients, rather than whole foods, so little attempt has been made to evaluate the contribution of whole grains in disease. Further, studies on vegetarians that show decreased risk of degenerative diseases are unable to separate the contribution of fruit and vegetable intake when compared with whole‐grain intake and protection from disease. The few epidemiological studies that have evaluated a role for whole grains suggest that they may have an important role in disease prevention and deserve more study.

Visual cues and the handwriting of older adults: A kinematic analysis.

Kinematic techniques determined the nature of any age-related changes in the fluency of handwriting movements and also the extent to which any changes can be related to a differential utilization of visual feedback. To quantitatively document the kinematics of handwriting movements, 24 young and 24 older adults were compared by having them write simple cursive letter Is 4 times on a graphics tablet, under 4 different visual conditions (no ink, ink, lines, and goggles). Pen tip position was sampled at 200 Hz, from which kinematic indexes of movement efficiency and consistency were derived. Quantitative differences in movement trajectories were found in the older adults, who produced less efficient movements with a concomitant increased utilization of external visual cues. Older adults made a differential use of visual feedback to modify movement trajectories, rather than to control the effects of neural noise. Handwriting movements of older adults resembled only to a limited extent those of patients with Parkinson's disease. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Permanent and specific transplantation tolerance induced by a nonmyeloablative treatment to a wide variety of allogeneic tissues: I. Induction of tolerance by a short course of total lymphoid irradiation and selective elimination of the donor-specific host lymphocytes

The long-term success of organ transplantation is limited by complications resulting from consistent nonspecific immunosuppression. Induction of stable, donor-specific tolerance remains the main goal of transplantation immunology. In this article, a new, nonmyeloablative method is described for induction of transplantation tolerance to fully mismatched bone marrow cells (BMC), bone marrow stromal precursors, heart muscle, and skin allografts. The method is based on pretransplant conditioning with no postgraft immunosuppression, and consists of a short course (six daily fractions of 200 cGy) of total lymphoid irradiation (sTLI), followed by selective elimination of donor-specific alloreactive cells of the host escaping low-dose sTLI. Donor-specific alloreactive cells were activated by intravenous inoculation with a high dose of donor BMC (3 x 10(7) cells) 1 day after sTLI, and eliminated by a single intraperitoneal dose (200 mg/kg) of cyclophosphamide given 1 day after cell transfer. Infusion of a low number of T cell-depleted BMC (3 x 10(6) cells) after tolerogenic preconditioning converted recipients to stable mixed chimeras free of graft-versus-host disease. The same treatment provided long-lasting acceptance of heterotopically transplanted allografts of the heart muscle and of the stromal precursors to the hematopoietic microenvironment. This treatment also led to acceptance and life-long survival of full-thickness donor skin allografts. However, skin allografts survived only in mice that received donor T cell-depleted BMC after cyclophosphamide and had 20-50% donor cells in the blood. Our results suggest that after sTLI, additional selective clonal deletion of residual host cells induces a state of long-lasting specific tolerance to a wide variety of donor-derived tissues.     

Magnetic characteristics of Ya?argil aneurysm clips

BACKGROUND: Metallic bioimplants are subject to great scrutiny in order to ensure that they are totally harmless to patients. Aneurysm clips are no exception to this rule. Considering the number of aneurysm clips used and their potential for injury, they should be evaluated very meticulously. Determining the magnetic characteristics of these clips is an important part of the evaluation process. In this study, a new method for evaluating magnetism is described and the importance of that information is briefly discussed. METHODS: Twenty Ya?argil aneurysm clips were analyzed using a vibrating sample magnetometer under 1.5 Tesla. This device is highly sensitive, and is capable of measuring the magnetism of small objects. RESULTS: Our measurements showed magnetism of the aneurysm clips ranged from 0.0334-0.1369 electromagnetic units (emu). CONCLUSIONS: Magnetometer measurements and real life tests under magnetic resonance imaging (MRI) have shown that these clips have a very low magnetism and are safe to use in 1.5 Tesla MRI scanners. This study also proves that the vibrating sample magnetometer is a useful device for analyzing the magnetism of aneurysm clips, and their emu values can be used as another industry standard in the production line to increase the safety of these clips.
