Effectiveness of cognitive-behavioral group therapy in quality of life and hope among patients with multiple sclerosis

Introduction: The present study was aimed at investigating the effectiveness of cognitive-behavioral group therapy in quality of life and hope among patients with multiple sclerosis (MS).Materials and Methods: In this clinical trial, using a quasi-experimental pretest-posttest control group design, 20 MS patients were selected through available sampling among the patients in Mashhad Multiple Sclerosis Association in 2016 and were randomly assigned into two experimental and control groups, each containing 10 subjects. The experimental group underwent cognitive-behavioral group therapy in 10 weekly sessions of 2 hours and the control group did not receive this treatment. In the pretest and posttest, Quality of Life Questionnaire-Short Form (SF-36) and Snyder ‎Adult Hope Scale (AHS)‎ were implemented on all the subjects of the experimental and control groups. Data was analyzed using analysis of covariance and t-test.Results: The results demonstrated that cognitive-behavioral group therapy significantly leads to increased overall index of quality of life and hope (p<0.001) in the experimental group compared to the control group. Further, out of quality of life components, dimensions of physical function, role limitation due to physical problems, fatigue or vitality, emotional health and general health of the experimental group showed a greater increase at the end of the intervention relative to the control group (p<0.001) and concerning other subscales, the difference between the two groups was not significant

A Modeling and Verification Approach to the Design of Distributed IMA Architectures Using TTEthernet

AbstractIntegrated Modular Avionics (IMA) architectures complemented with Time-Triggered Ethernet (TTEthernet) provides a strong platform to support the design and deployment of distributed avionic software systems. The complexity of the design and continuous integration of such systems can be managed using a model-based methodology. In this paper, we build on top of our extension of the AADL modeling language to model TTEthernet-based distributed systems and leverage model transformations to enable undertaking the verification of the system models produced with this methodology. In particular, we propose to transform the system models to a model suitable for a simulation with DEVS. We illustrate the proposed approach using an example of a navigation and guidance system and we use this example to show the verification of the contention-freedom property of TTEthernet schedule

Evaluation of Subcision for the Correction of the Prominent Nasolabial Folds

Background. A prominent nasolabial fold (NLF) is a cosmetic problem. Currently, numerous therapeutic modalities are available for pronounced NLFs with variable efficacy. Objective. To determine the efficacy and safety of subcision using a hypodermic needle for the correction of the prominent NLFs and its effect on skin elasticity. Methods. Sixteen patients with prominent NLFs underwent subcision. The investigators’ assessment of improvement and the patients’ satisfaction were both recorded 1 and 6 months after the procedure. Also, we evaluate the skin elasticity of NLFs before and after the treatment using a sensitive biometrologic device with the measurement of cutaneous resonance running time (CRRT). Results. Thirteen (81.25%) patients showed a moderate improvement at 1st month and 13 (81.25%) patients had at least a mild improvement at 6th month. There was no persistent side effect lasting more than a few days. Mean CRRT at 1 and 6 months after the treatment was significantly higher compared to the baseline. Conclusion. Subcision may be considered effective for the correction of pronounced NLFs. However, further controlled studies with larger sample size are necessary to assess the efficacy of this technique in particular with use of more objective assessment of skin biometric characteristics. This trial is registered with IRCT201108097270N1 (registered on January 27, 2012)

WasmWalker: Path-based Code Representations for Improved WebAssembly Program Analysis

WebAssembly, or Wasm, is a low-level binary language that enables execution of near-native-performance code in web browsers. Wasm has proven to be useful in applications including gaming, audio and video processing, and cloud computing, providing a high-performance, low-overhead alternative to JavaScript in web development. The fast and widespread adoption of WebAssembly by all major browsers has created an opportunity for analysis tools that support this new technology. In this study, we performed an empirical analysis on the root-to-leaf paths of the abstract syntax trees in the WebAssembly Text format of a large dataset of WebAssembly binary files compiled from over 4,000 source packages in the Ubuntu 18.04 repositories. After refining the collected paths, the initial number of over 800,000 paths was reduced to only 3,352 unique paths that appeared across all of the binary files. With this insight, we propose two novel code representations for WebAssembly binaries. These novel representations serve not only to generate fixed-size code embeddings but also to supply additional information to sequence-to-sequence models. Ultimately, our approach seeks to help program analysis models uncover new properties from Wasm binaries, expanding our understanding of their potential. We evaluated our new code representation on two applications: (i) method name prediction and (ii) recovering precise return types. Our results demonstrate the superiority of our novel technique over previous methods. More specifically, our new method resulted in 5.36% (11.31%) improvement in Top-1 (Top-5) accuracy in method name prediction and 8.02% (7.92%) improvement in recovering precise return types, compared to the previous state-of-the-art technique, SnowWhite

Evaluation and improvement of micro-surfacing mix design method and modelling of asphalt emulsion mastic in terms of filler-emulsion interaction

This Doctorate program focuses on the evaluation and improving the rutting resistance of micro-surfacing mixtures. There are many research problems related to the rutting resistance of micro-surfacing mixtures that still require further research to be solved. The main objective of this Ph.D. program is to experimentally and analytically study and improve rutting resistance of micro-surfacing mixtures. During this Ph.D. program major aspects related to the rutting resistance of micro-surfacing mixtures are investigated and presented as follow: 1) evaluation of a modification of current micro-surfacing mix design procedures: On the basis of this effort, a new mix design procedure is proposed for type III micro-surfacing mixtures as rut-fill materials on the road surface. Unlike the current mix design guidelines and specification, the new mix design is capable of selecting the optimum mix proportions for micro-surfacing mixtures; 2) evaluation of test methods and selection of aggregate grading for type III application of micro-surfacing: Within the term of this study, a new specification for selection of aggregate grading for type III application of micro-surfacing is proposed; 3) evaluation of repeatability and reproducibility of micro-surfacing mixture design tests: In this study, limits for repeatability and reproducibility of micro-surfacing mix design tests are presented; 4) a new conceptual model for filler stiffening effect on asphalt mastic of micro-surfacing: A new model is proposed, which is able to establish limits for minimum and maximum filler concentrations in the micro-surfacing mixture base on only the filler important physical and chemical properties; 5) incorporation of reclaimed asphalt pavement and post-fabrication asphalt shingles in micro-surfacing mixture: The effectiveness of newly developed mix design procedure for micro-surfacing mixtures is further validated using recycled materials. The results present the limits for the use of RAP and RAS amount in micro-surfacing mixtures; 6) new colored micro-surfacing formulations with improved durability and performance: The significant improvement of around 45% in rutting resistance of colored and conventional micro-surfacing mixtures is achieved through employing low penetration grade bitumen polymer modified asphalt emulsion stabilized using nanoparticles
