Search for a target image area based on geometrical parameters of multiple future pixels
Authors: Matuura Yosihumi , Saitoh Fumihiko 
Published: March 2009

AbstractThis paper proposes a method of measuring the two‐dimensional pose of an object by means of a voting process based on the geometrical parameters of selected future pixels. The proposed method can measure the location and inclination of an object even if the object has an arbitrary two‐dimensional pose in an image. In the template registration process, the geometrical parameters of multiple selected future pixels are registered in the template table. In the matching process, a target image area with a figure similar to a template image is sought by using the geometrical parameters of the future pixels. Experimental results show that the poses of objects with arbitrary locations and inclinations were recognized successfully by the proposed method with higher‐speed matching than by conventional methods. © 2009 Wiley Periodicals, Inc.

Direct products of automorphism groups of graphs

Published: March 2009

AbstractIn this article we study the product action of the direct product of automorphism groups of graphs. We generalize the results of Watkins [J. Combin Theory 11 (1971), 95–104], Nowitz and Watkins [Monatsh. Math. 76 (1972), 168–171] and W. Imrich [Israel J. Math. 11 (1972), 258–264], and we show that except for an infinite family of groups Sn × Sn, n≥2 and three other groups D4 × S2, D4 × D4 and S4 × S2 × S2, the direct product of automorphism groups of two graphs is itself the automorphism group of a graph. © 2009 Wiley Periodicals, Inc.

AbstractBACKGROUND:Deficits in information transfer between inpatient and outpatient physicians are common and potentially dangerous.OBJECTIVE:To evaluate the effect of a newly‐created electronic discharge summary.DESIGN AND PARTICIPANTS:Pre‐post evaluation of discharge summaries using a survey of outpatient physicians and a medical records review.MEASUREMENTS:Outpatient physicians' ratings of satisfaction with discharge summaries before and after implementation of an electronic discharge summary using a 5‐point Likert scale (1 = very dissatisfied; 5 = very satisfied). Additionally, 196 randomly selected discharge summaries before and after implementation were rated for timeliness and presence of 16 key content areas by 3 internists.RESULTS:Two hundred and twenty‐six of 416 (54%) and 256 of 397 (64%) outpatient physicians completed the baseline and postimplementation surveys. Satisfaction with quality and timeliness of discharge summaries improved with the use of the electronic discharge summary (mean quality rating 3.04 versus 3.64; P < 0.001, mean timeliness rating 2.59 versus 3.34; P < 0.001). A higher percentage of electronic discharge summaries were completed within 3 days of discharge as compared with dictated discharge summaries (44.8% versus 74.1%; P < 0.001). Several elements of the discharge summary were present more often with the electronic discharge summary, including discussion of follow‐up issues (52.0% versus 75.8%; P = 0.001), pending test results (13.9% versus 46.3%; P < 0.001), and information provided to the patient and/or family (85.1% versus 95.8%; P = 0.01).CONCLUSIONS:The use of an electronic discharge summary significantly improved the quality and timeliness of discharge summaries.

Complex plastic changes in the neuropeptide Y system during ethanol intoxication and withdrawal in the rat brain
Authors: Olling J.D. , Ulrichsen J. , Christensen D.Z. , Woldbye D.P.D. 
Published: March 2009

AbstractPrevious studies show that chronic ethanol treatment induces prominent changes in brain neuropeptide Y (NPY). The purpose of the present study was to explore ethanol effects at a deeper NPY‐system level, measuring expression of NPY and its receptors (Y1, Y2, Y5) as well as NPY receptor binding and NPY‐stimulated [35S]GTPγS functional binding. Rats received intragastric ethanol repeatedly for 4 days, and the NPY system was studied in the hippocampal dentate gyrus (DG), CA3, CA1, and piriform cortex (PirCx) and neocortex (NeoCx) during intoxication, peak withdrawal (16 hr), late withdrawal (3 days), and 1 week after last ethanol administration. NPY mRNA levels decreased during intoxication and at 16 hr in hippocampal regions but increased in the PirCx and NeoCx at 16 hr. NPY mRNA levels were increased at 3 days and returned to control levels in most regions at 1 week. Substantial changes also occurred at the receptor level. Thus Y1, Y2, and Y5 mRNA labelling decreased at 16 hr in most regions, returning to control levels at 3 days, except for PirCx Y2 mRNA, which increased at 3 days and 1 week. Conversely, increases in NPY receptor binding occurred in hippocampal regions during intoxication and in functional binding in the DG and NeoCx during intoxication and at 16 hr and in PirCx during intoxication and at 1 week. Thus this study shows that ethanol intoxication and withdrawal induce complex plastic changes in the NPY system, with decreased/increased gene expression or binding occurring in a time‐ and region‐specific manner. These changes may play an important role in mediating ethanol‐induced changes in neuronal excitability. © 2009 Wiley‐Liss, Inc.
Is there an indication for initial conservative management of pancreatic cystic lesions?
Authors: Grobmyer Stephen R. , Cance William G. , Copeland Edward M. , Vogel Stephen B. , Hochwald Steven N. 
Published: March 2009

AbstractBackgroundThe management of small pancreatic cystic lesions presents a clinical challenge.MethodsWe reviewed our experience with 78 patients who presented with a cystic pancreatic lesion who underwent operative management between 1995 and 2005. Data on cyst characteristics were analyzed in the context of pathologic findings following resection.ResultsAmong 78 patients, there were 55 (71%) females; median age 63 years. Patients presented with: an incidental finding (48%), pain (40%), acute pancreatitis (4%), other (8%). Operations were distal pancreatectomy (n = 47), pancreaticoduodenectomy (n = 16), and other (n = 15). Most patients had a non‐malignant lesion (n = 65, 83%) (mucinous cystadenoma (n = 29), serous cystadenoma (n = 15), IPMN without invasion (n = 8), pseudocyst (n = 8), other benign (n = 5)). Malignant lesions (adenocarcinoma, neuroendocrine tumor, and other) were found in 13 patients (17%). The risk of malignancy increased with size: <3 cm (n = 25), 4%; 3–5 cm (n = 23), 13%; and >5 cm (n = 30), 30%. Pre‐operative cyst fluid cytology was performed in 41 patients. The negative predictive value (NPV) of cytology for malignancy was 88% and the positive predictive value (PPV) was 80%. The NPV of CA 19‐9 for malignancy was 90%; the PPV was 50%.ConclusionsInitial conservative management of small cystic pancreatic lesions may be indicated in selected patients. J. Surg.

Magnetization transfer contrast imaging in bovine and human cortical bone applying an ultrashort echo time sequence at 3 Tesla

Published: March 2009

AbstractMagnetization transfer (MT) contrast imaging reveals interactions between free water molecules and macromolecules in a variety of tissues. The introduction of ultrashort echo time (UTE) sequences to clinical whole‐body MR scanners expands the possibility of MT imaging to tissues with extremely fast signal decay such as cortical bone. The aim of this study was to investigate the MT effect of bovine cortical bone in vitro on a 3 Tesla whole‐body MR unit. A 3D‐UTE sequence with a rectangular‐shaped on‐resonant excitation pulse and a Gaussian‐shaped off‐resonant saturation pulse for MT preparation was applied. The flip angle and off‐resonance frequency of the MT pulse was systematically varied. Measurements on various samples of bovine cortical bone, agar gel, aqueous manganese chloride solutions, and solid polymeric materials (polyurethane) were performed, followed by preliminary applications on human tibial bone in vivo. Direct on‐resonant saturation effects of the MT prepulses were calculated numerically by means of Bloch's equations. Corrected for direct saturation effects dry and fresh bovine cortical bone showed “true” MTR values of 0.26 and 0.21, respectively. In vivo data were obtained from three healthy subjects and showed MTR values of 0.30 ± 0.08. In vivo studies into MT of cortical bone might have the potential to give new insights in musculoskeletal pathologies. Magn Reson Med, 2009. © 2009 Wiley‐Liss, Inc.
Rapid methods for concurrent measurement of the RF‐pulse flip angle and the longitudinal relaxation time
Authors: Hsu Jung‐Jiin , Zaharchuk Greg , Glover Gary H. 
Published: March 2009

AbstractMeasuring both the flip angle (FA) and the longitudinal relaxation time T1 is essential in quantitative and longitudinal studies because the signal amplitude is dependent on these quantities. Conventional methods can only measure one of them at a time and require long scan times. In this work, two mutually consistent methods are developed; each can acquire multislice data for determining both the FA and T1 in a scan time about half the time needed for a conventional FA measurement. On the basis of a recent development of longitudinal‐relaxation measurement (Hsu and Lowe, J Magn Reson 2004;169:270–278; Hsu and Glover, J Magn Reson 2006;181:98–106), one of the methods uses RF pulse trains of two FAs whereas the other uses pulse trains of different pulse spacing. When only the FA or T1 is needed, the present methods can still be faster than conventional methods for the needed quantity. In benchmarking with a uniform‐density sample, both methods generate precise T1 values independent of the FA chosen (except at and near 90°). In the demonstration with three normal volunteers at 3 T, the T1 values of frontal and occipital white matter, putamen, and caudate are compared; the T1 values are in agreement with literature values and the intrasubject deviation is 0.2%–2.8%.

Minimax flow tree problems
Authors: Chen Hui , Campbell Ann , Thomas Barrett , Tamir Arie 
Published: March 2009

AbstractWe examine a class of problems that seeks to find tree‐structured networks that minimize the maximum cost among a subset of nodes in a graph. The cost metric is characterized by a series of parameters that can represent distance, flow volume, and delivery deadlines. Derived through variations in problem parameters, we present 17 different problems and discuss their worst‐case complexities. Fourteen of the problems are new to the literature. We show that some of the problems are 𝒩𝒫‐Complete and others are polynomially solvable. © 2009 Wiley Periodicals, Inc. NETWORKS, 2009
