A review of dosimetric impact of implementation of model-based dose calculation algorithms (MBDCAs) for HDR brachytherapy.

Phys Eng Sci Med 2021 Jun 17. Epub 2021 Jun 17.

Department of Medical Physics, Al-Neelain University, 11121, Khartoum, Sudan.

To obtain dose distributions more physically representative to the patient anatomy in brachytherapy, calculation algorithms that can account for heterogeneity are required. The current standard AAPM Task Group No 43 (TG-43) dose calculation formalism has some clinically relevant dosimetric limitations. Lack of tissue heterogeneity and scattered dose corrections are the major weaknesses of the TG-43 formalism and could lead to systematic dose errors in target volumes and organs at risk. Read More

Developing a simple box-behnken experimental design on the removal of doxorubicin anticancer drug using FeO/graphene nanoribbons adsorbent.

Environ Res 2021 Jun 12;200:111522. Epub 2021 Jun 12.

Department of Chemical Sciences (formerly Department of Applied Chemistry), University of Johannesburg, P.O. Box 17011, Doornfontein Campus, Johannesburg, 2028, South Africa.

This paper aims to develop a Box-Behnken experimental design system to optimize the removal process of doxorubicin anticancer drugs. For this goal, FeO/graphene nanoribbons was selected as adsorbent and removal of doxorubicin anticancer drug optimized using Box-Behnken experimental design with a selection of four effective factors. A three-level, four-factor Box-Behnken experimental design was used to assess the relationship between removal percentage as a dependent variable with adsorption weight (0. Read More

Consistent determination of the heating rate of light-absorbing aerosol using wavelength- and time-dependent Aethalometer multiple-scattering correction.

Sci Total Environ 2021 Jun 4;791:148277. Epub 2021 Jun 4.

GEMMA and POLARIS Centre, Università degli Studi di Milano-Bicocca, 20126 Milano, Italy.

Accurate and temporally consistent measurements of light absorbing aerosol (LAA) heating rate (HR) and of its source apportionment (fossil-fuel, FF; biomass-burning, BB) and speciation (black and brown Carbon; BC, BrC) are needed to evaluate LAA short-term climate forcing. For this purpose, wavelength- and time-dependent accurate LAA absorption coefficients are required. HR was experimentally determined and apportioned (sources/species) in the EMEP/ACTRIS/COLOSSAL-2018 winter campaign in Milan (urban-background site). Read More

Developing Relative Humidity and Temperature Corrections for Low-Cost Sensors Using Machine Learning.

Sensors (Basel) 2021 May 11;21(10). Epub 2021 May 11.

School of Electrical Engineering, University of Belgrade, Bulevar Kralja Aleksandra 73, 11120 Belgrade, Serbia.

Existing government air quality monitoring networks consist of static measurement stations, which are highly reliable and accurately measure a wide range of air pollutants, but they are very large, expensive and require significant amounts of maintenance. As a promising solution, low-cost sensors are being introduced as complementary, air quality monitoring stations. These sensors are, however, not reliable due to the lower accuracy, short life cycle and corresponding calibration issues. Read More

Experimental assessment of a linear actuator driven by magnetorheological clutches for automotive active suspensions.

J Intell Mater Syst Struct 2021 May 11;32(9):955-970. Epub 2021 Feb 11.

Créatek, Université de Sherbrooke, Sherbrooke, QC, Canada.

The main functions of automotive suspensions are to improve passenger comfort as well as vehicle dynamic performance. Simultaneously satisfying these functions is not possible because they require opposing suspension adjustments. This fundamental design trade-off can be solved with an active suspension system providing real-time modifications of the suspension behavior and vehicle attitude corrections. Read More

Testing different methods of estimating edaphic inputs in moss biomonitoring.

Sci Total Environ 2021 Jul 11;778:146332. Epub 2021 Mar 11.

CRETUS Institute, Ecology Area, Department of Functional Biology, Faculty of Biology, Universidade de Santiago de Compostela, 15782 Santiago de Compostela, Spain.

Although soil is known to contribute to the concentrations of elements in moss, protocols for atmospheric biomonitoring with terrestrial moss do not include recommendations on how to address this factor. As a result, researchers indiscriminately use a wide range of detection/correction methods without considering whether the results are equivalent. In this study, three of these methods were compared: i) use of the enrichment factor (EF) index; ii) calculation of the ratios of different elements in soil and moss, and subtraction of the contribution of soil concentrations from the raw concentrations of elements in mosses (SCS); and iii) positive matrix factorization (PMF), a receptor modelling method for source apportioning based on multivariate analysis techniques.

Psychiatric disorders as risk factors for type 2 diabetes: An umbrella review of systematic reviews with and without meta-analyses.

Diabetes Res Clin Pract 2021 May 7;176:108855. Epub 2021 May 7.

Department of Psychology, University of Southern Denmark, Odense, Denmark; STENO Diabetes Centre Odense, Odense University Hospital, Odense, Denmark; School of Psychology, Deakin University, Geelong, Australia. Electronic address:

Having a psychiatric disorder may increase the risk of developing type 2 diabetes[T2D] and this umbrella review aims to determine whether people with a psychiatric disorder have an increased risk of developing T2D and to investigate potential underlying mechanisms. A literature search was performed to identify systematic reviews of longitudinal studies investigating different psychiatric disorders as risk factors for incident T2D in humans (≥18 years). A total of 8612 abstracts were identified, 180 full-text articles were read, and 25 systematic reviews were included. Read More

On the suitability of using the diagonal Gaussian approximation in the calculation of the magnitude-based likelihood function.

Vladimir Y Lunin

Acta Crystallogr D Struct Biol 2021 May 19;77(Pt 5):663-673. Epub 2021 Apr 19.

Institute of Mathematical Problems of Biology RAS, Keldysh Institute of Applied Mathematics of Russian Academy of Sciences, Vitkevicha str. 1, Pushchino, Moscow Region 142290, Russian Federation.

Statistical likelihood maximization is currently one of the main tools in computational procedures in biological crystallography. In these procedures, the likelihood function is calculated, as a rule, within the framework of a diagonal Gaussian approximation (DGA) of the joint probability distribution of the real and imaginary parts of a set of structure factors. This approximation assumes pairwise uncorrelated values of various structure-factor components. Read More

X-ray tomographic reconstruction and segmentation pipeline for the long-wavelength macromolecular crystallography beamline at Diamond Light Source.

J Synchrotron Radiat 2021 May 20;28(Pt 3):889-901. Epub 2021 Apr 20.

Diamond Light Source Ltd, Diamond House, Harwell Science and Innovation Campus, Fermi Avenue, Didcot OX11 0DE United Kingdom.

In this paper a practical solution for the reconstruction and segmentation of low-contrast X-ray tomographic data of protein crystals from the long-wavelength macromolecular crystallography beamline I23 at Diamond Light Source is provided. The resulting segmented data will provide the path lengths through both diffracting and non-diffracting materials as basis for analytical absorption corrections for X-ray diffraction data taken in the same sample environment ahead of the tomography experiment. X-ray tomography data from protein crystals can be difficult to analyse due to very low or absent contrast between the different materials: the crystal, the sample holder and the surrounding mother liquor.

Algorithm of FBG Spectrum Distortion Correction for Optical Spectra Analyzers with CCD Elements.

Sensors (Basel) 2021 Apr 16;21(8). Epub 2021 Apr 16.

College of Dentistry, University of Mustansiriyah, Baghdad 14022, Iraq.

Nonlinear spectrum distortions are caused by the peculiarities of the operation of charge-coupled device elements (CCD), in which the signal exposition time (Time of INTegration-TINT) is one of the significant parameters. A change of TINT on a CCD leads to a nonlinear distortion of the resulting spectrum. A nonlinear distortion of the spectrum, in turn, leads to errors in determining the central wavelength of fiber Bragg gratings (FBGs) and spectrally sensitive sensors, which, in general, negatively affects the accuracy of the measuring systems.
