Deep neural network-based approach to improving radiomics analysis reproducibility in liver cancer: effect on image resampling.

Phys Med Biol 2021 Jul 22. Epub 2021 Jul 22.

Nuclear & Radiological Engineering and Medical Physics Programs, Woodruff School of Mechanical Engineering, Georgia Institute of Technology, Atlanta, GA, USA, Atlanta, Georgia, UNITED STATES.

Objectives: To test the effect of traditional up-sampling slice thickness (ST) methods on the reproducibility of CT radiomics features of liver tumors and investigate the improvement using a deep neural network (DNN) scheme.

Methods: CT images with ≤ 1 mm ST in the public dataset were converted to low resolution (3 mm, 5 mm) CT images. A DNN model was trained for the conversion from 3 mm-ST and 5 mm-ST to 1 mm-ST and compared with conventional interpolation-based methods (cubic, linear, nearest) using structural similarity (SSIM) and peak-signal-to-noise-ratio (PSNR).

Extracurricular Physical Activities and the Condition of Being an Only Child as a Conditioning Factor in the Psychomotor Development of 5-Year-Old Children.

Front Pediatr 2021 5;9:684418. Epub 2021 Jul 5.

Degree in Early Childhood Education and Primary Education, Faculty of Education, International University of la Rioja, Madrid, Spain.

In early childhood education, there is a great interdependence among motor, affective, and cognitive development. A better understanding of psychomotor development and its variables by pediatricians and those who oversee educational tasks at this stage of development, such as teachers, psychologists, counselors, and parents themselves, can influence the design of educational intervention proposals. To that effect, the present study aims to analyze the influence of some family characteristics such as the condition of being an only child or having siblings and whether the child carries out extracurricular activities linked to physical activities and sports.

Dynamic Modeling of Cable Driven Elongated Surgical Instruments for Sensorless Grip Force Estimation.

IEEE Int Conf Robot Autom 2016 May 9;2016:4128-4134. Epub 2016 Jun 9.

Departments of Electrical Engineering, Bioengineering, Mechanical Engineering, and Surgery, University of Washington, Seattle, WA, USA 98195.

Haptic feedback plays a key role in surgeries, but it is still a missing component in robotic Minimally Invasive Surgeries. This paper proposes a dynamic model-based sensorless grip force estimation method to address the haptic perception problem for commonly used elongated cable-driven surgical instruments. Cable and cable-pulley properties are studied for dynamic modeling; grip forces, along with driven motor and gripper jaw positions and velocities are jointly estimated with Unscented Kalman Filter and only motor encoder readings and motor output torques are assumed to be known.

Front Psychol 2021 5;12:700770. Epub 2021 Jul 5.

Department of Psychology, Sociology and Philosophy, University of Leon, Leon, Spain.

Research has shown that writers seem to follow different writing strategies to juggle the high cognitive demands of writing. The use of writing strategies seems to be an important cognitive writing-related variable which has an influence on students' writing behavior during writing and, therefore, on the quality of their compositions. Several studies have tried to assess students' writing preferences toward the use of different writing strategies in University or high-school students, while research in primary education is practically non-existent.

Construct validity of the OCTOPuS stratification algorithm for allocating patients with knee osteoarthritis into subgroups.

BMC Musculoskelet Disord 2021 Jul 21;22(1):633. Epub 2021 Jul 21.

Department of Rehabilitation Medicine, Amsterdam UMC, Location VUmc, Amsterdam, Netherlands.

Background: We recently developed a model of stratified exercise therapy, consisting of (i) a stratification algorithm allocating patients with knee osteoarthritis (OA) into one of the three subgroups ('high muscle strength subgroup' representing a post-traumatic phenotype, 'low muscle strength subgroup' representing an age-induced phenotype, and 'obesity subgroup' representing a metabolic phenotype) and (ii) subgroup-specific exercise therapy. In the present study, we aimed to test the construct validity of this algorithm.

Methods: Data from five studies (four exercise therapy trial cohorts and one cross-sectional cohort) were used to test the construct validity of our algorithm by 63 a priori formulated hypotheses regarding three research questions: (i) are the proportions of patients in each subgroup similar across cohorts? (15 hypotheses); (ii) are the characteristics of each of the subgroups in line with their proposed underlying phenotypes? (30 hypotheses); (iii) are the effects of usual exercise therapy in the 3 subgroups in line with the proposed effect sizes? (18 hypotheses). Read More

Assist Technol 2021 Jul 21. Epub 2021 Jul 21.

Department of Mechanical Engineering and Mechatronics, Faculty of Engineering, Ariel University.

The writing process is a complex task involving dexterous manipulation of the writing instrument by the hand digits and biomechanical ergonomic factors that contribute to handwriting efficiency and productivity. We describe a pilot study using an instrumented writing apparatus-a sensor (pen) and a digitized writing surface (tablet)-to measure the pen-grip kinetics (digit forces) and the pen pressure applied to the tablet during a writing task.
