Impact of Model Shape Mismatch on Reconstruction Quality in Electrical Impedance Tomography
2012
Electrical impedance tomography (EIT) is a low-cost, noninvasive and radiation free medical imaging modality for monitoring ventilation distribution in the lung. Although such information could be invaluable in preventing ventilator-induced lung injury in mechanically ventilated patients, clinical application of EIT is hindered by difficulties in interpreting the resulting images. One source of this difficulty is the frequent use of simple shapes which do not correspond to the anatomy to reconstruct EIT images. The mismatch between the true body shape and the one used for reconstruction is known to introduce errors, which to date have not been properly characterized. In the present study we…
Construct validity of the anxiety sensitivity index-3 in clinical samples
2012
"Using two clinical samples of patients, the presented studies examined the construct validity of the recently revised Anxiety Sensitivity Index-3 (ASI-3). Confirmatory factor analyses established a clear three-factor structure that corresponds to the postulated subdivision of the construct into correlated somatic, social, and cognitive components. Participants with different primary clinical diagnoses differed from each other on the ASI-3 subscales in theoretically meaningful ways. Specifically, the ASI-3 successfully discriminated patients with anxiety disorders from patients with nonanxiety disorders. Moreover, patients with panic disorder or agoraphobia manifested more somatic concerns …
COSTRUIRE LA FRONTIERA : l’architettura a Malta fra XVI e XVII secolo
2021
L’architettura di età moderna a Malta è il prodotto di una comunità di frontiera, continuamente animata da un flusso ininterrotto di tecnici, religiosi e diplomatici. Dall’ultima stagione del gotico all’esordio dell’età barocca, il cantiere maltese si è alimentato di stimoli e riferimenti spiccatamente eterogenei, a partire dai quali si delinea un orizzonte culturale di portata europea. Tra XVI e XVII secolo l’arcipelago maltese ospita quindi un sorprendente laboratorio di sperimentazione e contaminazione, di linguaggi e tecnologie che trovano massima espressione nella costruzione in pietra da taglio.
The decision-making process for breast reconstruction after cancer surgery: Representations of heterosexual couples in long-standing relationships
2017
Objectives Most people deal with intrusive life events such as cancer and the care trajectory together with their intimate partners. To our knowledge, no research has studied the involvement of the partner in the decision-making process regarding breast reconstruction (BR) after cancer. This study aimed to gain a better understanding of the couples’ decision-making process for BR in the cancer context and particularly to investigate the partners’ involvement in this process. Method Eighteen participants (nine women who underwent a mastectomy following a first breast cancer and their intimate partners) took part in this study. We conducted semidirective interviews, and a general inductive ap…
Different Hydraulic Constructs to Optimize the Venous Drainage of DIEP Flaps in Breast Reconstruction: Decisional Algorithm and Review of the Literat…
2020
Venous congestion is the most common perfusion-related complication of deep inferior epigastric artery perforator (DIEP) flap. Several hydraulic constructs can be created for venous superdrainage in case of flap venous engorgement or as a preventive measure. These can be classified based on the choice of the draining vein of the flap, either a second deep inferior epigastric vein (DIEV) or a superficial inferior epigastric vein (SIEV), and of the recipient vein, either a vein of the chest or the DIEV. Background Venous congestion is the most common perfusion-related complication of deep inferior epigastric artery perforator (DIEP) flap. Several hydraulic constructs can be created for venou…
Similar but Different? The influence of job satisfaction, organizational commitment and person-job fit on individual performance in the continuum bet…
2022
Permanent organizations and temporary organizations, such as projects, represent two poles of a continuum of organizational temporariness. The literature has shown that organizational temporariness can influence organizational outcomes and employee behavior. Using a sample of 341 members of temporary organizations, we investigate job satisfaction and organizational commitment in a permanent organization and person-job fit in a temporary organization as antecedents of employee performance. We further examine how the degree of organizational temporariness moderates these relationships. The findings show that job satisfaction and organizational commitment negatively influence employee performa…
Reconstruction of mandibular defects using vascularized fibular osteomyocutaneous flap combined with nonvascularized fibular flap
2019
Background The height of single-layer fibular flap is not long enough to return to the ideal height of the mandible. While the double-layer vascularized fibular osteomyocutaneous flap(VFF) is more complicated in shaping and fixation, along with a longer operation time. The aim of this study was to investigate the clinical effect of VFF combined with nonvascularized fibular flap(NVFF) in the reconstruction of mandibular defect. Material and Methods From September 2016 to June 2018, 15 patients with benign mandibular tumors underwent reconstruction with VFF and NVFF. SimPlant Pro ™ software (version 11.04) was used to simulate reconstruction of the mandible preoperatively. Results All patient…
Insights Into the Inside - A Quantitative Histological Study of the Explosively Moving Style in Marantaceae.
2018
This study aims to identify the histological basis for the extraordinary, fast movement of the style in Marantaceae. Although this explosive pollination mechanism was subject of many studies, quantitative measurements to document volumetric changes have never been conducted. Based on physical parameters and limitations (poroelastic time), the movement itself is by far too fast to be explained by turgor changes solely. Therefore, we address the hypothesis that the style contains elastic structures to store energy allowing the fast movement. We provide an experimental approach in Goeppertia bachemiana to identify histological differences of styles in various states, i.e., steady, unreleased, …
CLINICAL OUTCOMES OF SELF-EXPAMDABLE METALLIC STENTS IN PALLIATION OF MALIGNANT ANASTOMOTIC STRICTURES: A SINGLE CENTER EXPERIENCE
2015
Background: self-expandable metallic stents (SEMS) are employed as the preferred non surgical palliative treatment for gastric outlet obstruction due to malignancies. Metallic stents are often employed to treat malignant anastomotic obstructions after surgicsl interventions as esophagojejunostomy, gastrojejunostomy and esophagogastrojejunostomy. Methods: this case series reports prospectively the clinical outcomes of SEMS in the palliative care of malignant anastomotic strictures caused by the recurrence gastric cancer follwing gastric surgery as oncological curative treatment, in a series of nine consecutive patients, treated between January 2009 and december 2012 in our center. Results: N…
Enforcing mobile security with location-aware role-based access control
2013
This paper describes how location-aware role-based access control RBAC can be implemented on top of the Geospatial eXtensible Access Control Markup Language GeoXACML. It furthermore sketches how spatial separation of duty constraints both static and dynamic can be implemented using GeoXACML on top of the XACML RBAC profile. The solution uses physical addressing of geographical locations, which facilitates easy deployment of authorisation profiles to the mobile device. Location-aware RBAC can be used to implement location-dependent access control and also other security enhancing solutions on mobile devices, such as location-dependent device locking, firewall, intrusion prevention or payment…
