Efficient N-Dimensional surface estimation using Crofton formula and run-length encoding
Authors: Lehmann Gaetan , Legland David
Published: January 2022

Unlike the measure of the area in 2D or of the volume in 3D, the perimeter and the surface are not easily measurable in a discretized image. In this article we describe a method based on the Crofton formula to measure those two parameters in a discritized image. The accuracy of the method is discussed and tested on several known objects. An algorithm based on the run-length encoding of binary objects is presented and compared to other approaches. An implementation is provided and integrated in the LabelObject/LabelMap framework contributed earlier by the authors.

Published: January 2022

The Medical Imaging Interaction Toolkit (MITK) is an opensource toolkit for the development of interactive medical image analysis software. MITK is based on the open-source Insight Toolkit (ITK) and Visualization Toolkit (VTK) and extends them with features required for interactive systems. ITK is used for the algorithmic scope and general infrastructure, VTK for visualization. Key features of MITK are the coordination of multiple 2D and 3D visualizations of arbitrary data, a general interaction concept including undo/redo, and its extendibility and flexibility to create tailored applications due to its toolkit character and different layers of hidden complexity. The paper gives a brief introduction into the overall concepts and goals of the MITK approach. Suggestions and participation are welcome. MITK is available at www.mitk.org.
An Implementation of Parallel Fast Marching Using the Message Passing Interface
Authors: Hobbs Kevin
Published: January 2022

This document introduces a program based on the algorithm described by Maria Cristina Tugurlan. The program uses file readers, image filters, and file writers from the Insight Toolkit ITK www.itk.org. It produces as output an image whose values are the times of first arrival of a wavefront that spreads from seed points with a speed at every point equal to the input image intensity. It performs the computation in parallel on distributed memory computers using the Message Passing Interface MPI. Each MPI process reads a small piece of the input image into memory. It computes fast marching on its piece. It sends and receives the values from fast marching at piece boundaries. It recalculates fast marching a number of times set from the command line using the new boundary values each time. Each MPI process writes only a small piece of the output file.

A substantial difference is seen when the output of MPI fast marching is compared to the output of serial fast marching. This difference may be acceptable for some uses. The program should be able to handle input images that are too large to fit in the memory of a single computer.

Tetrahedral mesh generation for medical imaging
Authors: Fedorov Andriy , Chrisochoides Nikos , Kikinis Ron , Warfield Simon
Published: January 2022

We describe the open source implementation of an adaptive tetrahedral mesh generator particularly targeted for non-rigid FEM registration of MR images. While many medical imaging applications require robust mesh generation, there are few codes available. Moreover, most of the practical implementations are commercial. The algorithm we have implemented has been previously evaluated for simulations of highly deformable objects, and the preliminary results show its applicability to the targeted application. The implementation we describe is open source and will be available within Insight Toolkit.
Changes to itk::PathToImageFilter.
Authors: Pincus Zachary
Published: January 2022

I have made some changes to make itk::PathToImageFilter to make it a usable base class. There were some problems with the CVS version, including: (1) this ase classhad actual filter functionality, (2) the mechanism for specifying the size, spacing, origin, etc., of the output image was incomplete, contrary to ITK convention, and hard to extend, and (3) the documentation specified that the filter would calculate the size of the output image from the path, but it did not.

I solved these problems by (1) moving the filter functionality to itk::TracePathOnImageFilter, (2) requiring that filter->GetOutput()->Set…(…) should be used to set the information for the output image, and (3) providing methods to calculate the correct image region a path inhabits, and a boolean flag to specify whether that calculation should be done (default true).
Incorporating Metric Flows and Sparse Jacobian Transformations in ITK
Authors: De craene Mathieu , Du bois d'aische Aloys , Macq Benoit , Warfield Simon
Published: January 2022

Various metrics have been proposed in the literature for performing intrinsic automatic image to image registration. Among these measures, mutual information is a very popular one because of its robustness and accuracy for a wide variety of applications. In this paper, we propose a filter for performing non-rigid registration by estimating a dense deformation field derived from the mutual information metric. This filter takes place in the ITK PDE deformable registration design like the Demons algorithm of Thirion. We also show how the concept of metric flow is conceptually linked to the concept of metric derivative for a prior transformation model by the transformation jacobian. We also suggest a sparse implementation of the GetJacobian() method for reducing the computation time of a metric derivative for local transformations models.
ItkImageFunctionImageFilter: A New Filter To Apply An itkImageFunction To Every Pixel In An itkImage
Authors: Doria David
Published: January 2022

This document presents a new class to apply an itkImageFunction to every pixel in an itkImage. This functionality is almost identical to itkUnaryFunctorImageFilter, but it uses an itkImageFunction rather than an itk::Functor. As some functionalities in ITK seem to have been implemented as image functors (itk::Functor::AND, itk::Functor::Atan, etc.) while other seems to have been implemented as itkImageFunction’s (itk::BinaryThresholdImageFunction, itk::CentralDifferenceImageFunction, etc.), it seems reasonable to be able to apply any of these operations to an entire image.

Exporting Contours to DICOM-RT Structure Set
Authors: Gorthi Subrahmanyam , Bach Cuadra Meritxell , Thiran Jean-Philippe
Published: January 2022

This paper presents an ITK implementation for exporting the contours of the automated segmentation results to DICOM-RT Structure Set format. The “radiotherapy structure set” (RTSTRUCT) object of the DICOM standard is used for the transfer of patient structures and related data, between the devices found within and outside the radiotherapy department. It mainly contains the information of regions of interest (ROIs) and points of interest (E.g. dose reference points). In many cases, rather than manually drawing these ROIs on the CT images, one can indeed benefit from the automated segmentation algorithms already implemented in ITK. But at present, it is not possible to export the ROIs obtained from ITK to RTSTRUCT format. In order to bridge this gap, we have developed a framework for exporting contour data to RTSTRUCT. We provide here the complete implementation of RTSTRUCT exporter and present the details of the pipeline used. Results on a 3-D CT image of the Head and Neck (H&N) region are presented.

Published: January 2022

Introduction:

The relationship between surgeon experience and cervical fusion outcomes has yet to be assessed. We investigate perioperative characteristics, patient-reported outcomes (PROMs), and minimal clinically important difference (MCID) achievement after anterior cervical diskectomy and fusion (ACDF) by the volume of cases done throughout an orthopaedic spine surgeon's career.

Methods:

ACDF procedures between 2005 and 2020 were identified. Group I included the first half of ACDF cases (#1-#321). PROMs were introduced in the second half of the ACDF cases; thus, the next 322 cases were subdivided to compare PROM and MCID between subgroups (cases #322 to #483 = group II and #484 to #645 = group III). PROMs, including VAS back/leg, Oswestry Disability Index (ODI), Short Form-12 Physical Composite Score, and PROMIS-PF, were collected preoperatively/postoperatively. Demographics, perioperative variables, mean PROMs, and MCID achievement were compared between groups and subgroups using the Student t-test and chi-square. Logistic regression evaluated MCID achievement using the established threshold values.

Results:

A total of 642 patients were included (320 in group I, 161 in group II, and 161 in group III). The latter cases had significantly decreased surgical time, blood loss, and postoperative length of stay in comparison of groups and subgroups (P ≤ 0.002, all). CT-confirmed 1-year arthrodesis rates were increased among the latter cases (P = 0.045). Group II had significantly higher arthrodesis rates than group III (P = 0.039). The postoperative complication rates were lower in the latter cases (P < 0.001, all), whereas subgroup analysis revealed lower incidence of urinary retention and other complications in group III (P ≤ 0.031, all). Mean PROMs were significantly inferior in group II versus group III for VAS neck at 6 months (P = 0.030), Neck Disability Index at 6 months preoperatively (P ≤ 0.022, both), Short Form-12 Physical Composite Score at 12 weeks/2 years (P ≤ 0.047, both), and PROMIS-PF at 12 weeks/6 months (P ≤ 0.036, both). The MCID attainment rates were higher among group III for VAS neck/Neck Disability Index at 2 years (P ≤ 0.005) and overall achievement across all PROMs (P ≤ 0.015, all).

Discussion:

Increased ACDF case volume may lead to markedly decreased surgical time, blood loss, and length of postoperative stay as well as improved clinical outcomes in pain, disability, and physical function.

Soil-Root System Withholding Strength for River Bank Stability
Authors: HASSAN IR. PROF. DR RUSLAN HASSAN , Ibau Ding
Published: January 2022

The ability of vegetation to stabilise soils is frequently employed in slope stabilisation projects including riverbank restoration activity. Soil block samples permeated with roots of Bermuda Grass commonly used for remediation and riverbank restoration were tested in a direct shear apparatus. Shear stress results of rooted soils were compared with results of un-vegetated soil bloc—s with similar soil types. The increase of shear strength was determined by comparing shear stresses at speciic horizontal displacements. The relative strength increase at the same displacement was 27.3 kPa compared to 19.1 kPa for un-vegetated soil at a displacement of 13.3cm (Location 3). The relative strength increase at the same displacement of 13.3cm was 43.5% for Location 1 and 42.4% for Location 2. The shear stresses in most of the blocks with roots were still increasing at the end of the test (maximum displacement of about 15cm). These conservative root biomass values and the shearing resistance obtained can be used in the assessment of the stability of the existing vegetated slopes and in the design of vegetated riverbanks.

Published: January 2022

The World Health Organization suggests the visual examination of stained sputum smear samples as a preliminary and basic diagnostic technique for diagnosing tuberculosis which is the most common infectious disease in the world. Due to the fact that the visual examination of slide samples performed by expert laboratory technicians requires much time and the process is prone to mistake, an accurate diagnosis of disease is provided with computer aided automatic diagnosis methods. In this study, the usage of swarm intelligence algorithms based on entropy information are proposed for detecting the tuberculosis bacilli as an ovelap approach in segmentation of microscopic images. The microscopic images used in the study are taken from smear samples in which the background concentration is low and bacilli concentration is low and high. An optimum threshold value in gray-level microscopic image is determined using the bi-level entropy based Particle Swarm Optimization, Firefly Algorithm, Cuckoo Search Optimization and Flower Pollination Algorithm. The acquired visual results show that the proposed swarm intelligence algorithms are quite successful in segmentation of microscopic images.

Preparation of black-TiO2 and its application in photocatalytic removal of methyl orange dye
Authors: Nguyen Quang Long
Published: January 2022

For a few decades, Titanium Dioxide (TiO2) has been the most studied photocatalyst due to its significant optical property. In the paper, TiO2 pigment powder (Anatase form) was selected as a precursor to prepare a variety of Black-TiO2 samples, and the typical material was then evaluated for its photocatalytic activity in organic pollutant treatment. Some properties of Black-TiO2 were determined via common methods such as sensory analysis, X-Ray diffraction, and bandgap measurement obtained from UV-Vis spectroscopy. As a result, the material was successfully converted to more than 40% organic pollutant as Methyl Orange (C14H14N3NaO3S) for an hour, as two times higher than that of the amount converted by pristine TiO2. In addition, Black-TiO2 performed much better photocatalytic activity in an acidic medium in comparison with a neutral one, and the material also remained its activity as more than 90% after three time-continuous recycling operations.

Compensating a Legal Person for Moral Damage in Jordanian Law
Authors: Almaharmeh Mohammad Mahjoob
Published: January 2022

The issue of compensating the legal person for the moral damage it causes to it has raised a great argument of controversy in Jordan, especially in light of the refusal to recognize the rights attached to the natural person of the legal person. This research came to identify the legal nature of the legal personality and the moral damage and the position of the Jordanian law on it, and to determine the feasibility, adequacy and appropriateness of the legal texts contained in the Jordanian civil law in knowing the extent to which the legal person may be compensated for moral damage. Using the opinions of jurists and judicial and explanatory decisions, the researcher has found that moral damage has multiple forms, a research that arises from the act and assault carried out by the aggressor. As a result, it is not appropriate to limit moral damage to rigid legal texts based on what is stated in the legislation and decisions of the esteemed Court of Cassation, as the researcher recommends. The Jordanian legislator should include general provisions clarifying the civil liability of the legal person, and the researcher recommends a separate chapter in the civil law to talk about the moral damage and its multiple meanings and aspects and how to rule for compensation and claim it.
MODIFIED CORRELATION WEIGHT K-NEAREST NEIGHBOR CLASSIFIER USING TRAINING DATASET CLEANING METHOD
Authors: Kette Efraim Kurniawan Dairo
Published: January 2022

In pattern recognition, the k-Nearest Neighbor (kNN) algorithm is the simplest non-parametric algorithm. Due to its simplicity, the model cases and the quality of the training data itself usually influence kNN algorithm classification performance. Therefore, this article proposes a sparse correlation weight model, combined with the Training Data Set Cleaning (TDC) method by Classification Ability Ranking (CAR) called the CAR classification method based on Coefficient-Weighted kNN (CAR-CWKNN) to improve kNN classifier performance. Correlation weight in Sparse Representation (SR) has been proven can increase classification accuracy. The SR can show the 'neighborhood' structure of the data, which is why it is very suitable for classification based on the Nearest Neighbor. The Classification Ability (CA) function is applied to classify the best training sample data based on rank in the cleaning stage. The Leave One Out (LV1) concept in the CA works by cleaning data that is considered likely to have the wrong classification results from the original training data, thereby reducing the influence of the training sample data quality on the kNN classification performance. The results of experiments with four public UCI data sets related to classification problems show that the CAR-CWKNN method provides better performance in terms of accuracy.

The central part of the paper analyses the functions of euphemisms in Croatian public communication, the ways and mechanisms of creating euphemisms in the Croatian language and the semantic areas in which euphemisms are more significantly represented. The research started from the hypothesis that euphemisms have deviated from their original purpose - to beautify the expression and save one’s own or someone else’s face - and that euphemisms are increasingly used in public communication to manipulate the interlocutor. To test the hypothesis, research was conducted using a bottom-up methodological approach that involved selecting materials from the corpus by “manually” browsing and following news and announcements in the electronic media, classifying euphemisms by types, functions, semantic areas and ways of formation, and concluding their use in Croatian public communication space.

Objective: The effects of maternal undernutrition during midgestation on muscle fiber histology, myosin heavy chain (MyHC) expression, methylation modification of myogenic factors, and the mammalian target of rapamycin (mTOR) signaling pathway in the skeletal muscles of prenatal and postnatal goats were examined.Methods: Twenty-four pregnant goats were assigned to a control (100% of the nutrients requirement, n = 12) or a restricted group (60% of the nutrients requirement, n = 12) between 45 and 100 days of gestation. Descendants were harvested at day 100 of gestation and at day 90 after birth to collect the femoris muscle tissue.Results: Maternal undernutrition increased (p<0.05) the fiber area of the vastus muscle in the fetuses and enhanced (p<0.01) the proportions of MyHCI and MyHCIIA fibers in offspring, while the proportion of MyHCIIX fibers was decreased (p<0.01). DNA methylation at the +530 cytosine-guanine dinucleotide (CpG) site of the myogenic factor 5 (MYF5) promoter in restricted fetuses was increased (p<0.05), but the methylation of the MYF5 gene at the +274,280 CpG site and of the myogenic differentiation (MYOD) gene at the +252 CpG site in restricted kids was reduced (p<0.05). mTOR protein signals were downregulated (p<0.05) in the restricted offspring.Conclusion: Maternal undernutrition altered the muscle fiber type in offspring, but its relationship with methylation in the promoter regions of myogenic genes needs to be elucidated.

Objective: The beneficial effects of glycine were tested in piglets with diquat-induced hepatic injury.Methods: Thirty-two piglets were assigned by a 2×2 factorial experimental design including glycine supplementation and diquat challenge. After 3 weeks of feeding with a basic diet or a 1% glycine supplemented diet, piglets were challenged with diquat or saline. After 1 week later, the piglets were slaughtered and samples were collected.Results: Our results indicated that glycine alleviated diquat induced morphological hepatic injury, decreased the activities of plasma alanine aminotransferase, aspartate aminotransferase and glutamyl transpeptidase in the piglets under diquat challenge, and increased total antioxidant capacity and antioxidative enzyme activity significantly. Adding glycine enhanced the concentrations of hepatic adenosine triphosphate and adenosine diphosphate. Transmission electron microscope observation showed that diquat induced clear hepatocytes ferroptosis and its effect could be alleviated by glycine to a certain degree. Moreover, glycine significantly affected mRNA and protein expression of ferroptosis-related signals in the liver.Conclusion: These results demonstrated that glycine attenuated liver damage via inhibiting ferroptosis.

Objective: The objective of this study was to determine the appropriate amount of eri silkworm pupae meal (Samia ricini) to add to the broiler diet.Methods: Two hundred 1-day-old male chicks with initial weight at 50.03±0.56 g/chick were divided into four groups (five replicates per group and ten chicks per replicate): a control group fed a corn-soybean diet and experimental groups supplemented with 5%, 10%, or 15% eri silkworm pupae meal. All experimental diets were isocaloric and isonitrogenous and formulated respecting nutrient requirements. Growth performances were collected during the experimental period and other parameters were collected at the end of experiment when broilers reached thirty-eight days old.Results: A higher cold carcass weight and skin yellowness in the broilers fed 10% eri silkworm pupae meal compared with the other groups (p<0.05). Therefore, supplementation with 10% eri silkworm pupae meal is suggested for the broiler diet formulation because it did not cause any serious negative consequences on growth performance, health status, carcass characteristics and meat quality. However, the usage of eri silkworm pupae meal at 15% is not recommend because it led to negative outcomesConclusion: The addition of eri silkworm pupae at 10% can be used as an alternative protein sources for broiler chickens which provided benefits on cold carcass weight and skin yellowness without adverse effects.

Objective: Free-range systems have been increasingly available to the consumer due to increased demand for more sustainable meat-products. In the current study, the effect of free-range (FR) and cage system (CS) was explored on growth performance, meat quality and oxidation products in Italian White breed rabbits during the growing-fattening phase (5 to 13 weeks of age).Methods: Forty rabbits were randomly allotted to two treatment groups according to the rearing system, and each treatment group was replicated five times with four subjects in each replicate (20 rabbits per treatment-group). All rabbits fed the same diet as pelleted, and under FR system, no additional feeds were available to animals.Results: Rearing system had significant effect on rabbit growth performance, where CS group resulted in higher final body weight (p<0.045) and gain (p<0.029) and better feed efficiency (p<0.025) compared to FR rabbits. Most carcass traits were not affected by rearing system; however, a reduction of abdominal fat content (p<0.015) and meat lipids (p<0.034) was observed in FR rabbits. Rearing system had no effects on meat fatty acid profile, whereas meat from FR rabbits resulted less susceptible to lipid and protein oxidation compared to caged animals.Conclusion: In overall, FR system could be suggested as a substitute for conventional caged system because of FR system preserved rabbit meat from oxidation.

Objective: The study was aimed to investigate the rules of postprandial changes in intestine digesta dry matter (DM) flow and amino acid digestibility of growing pigs fed low-protein (LP) diets made of different starch.Methods: Eight barrows (28.8±2.1 kg) with a T-cannula at the distal ileum were randomly allotted to an 8×3 Youden square design. Treatments included: waxy corn starch LP (WLP); corn starch LP (CLP) and pea starch LP (PLP). Diets were given at 08:00 and 20:00. Digesta samples were collected in six 2-h stages from 08:00 to 20:00.Results: The Cr concentrations of ileal digesta increased and then decreased in WLP and CLP, while increased continuously in PLP as time passed after postprandial (p<0.05). Higher average Cr concentrations (0.78% and 0.84% vs 0.70%; p<0.05) and lower average DM flow (181.1 g/kg and 166.3 g/kg vs 240.3 g/kg; p<0.001) were observed in WLP and CLP, compared with PLP. The apparent ileal digestibility coefficient of most amino acids in WLP and CLP increased compared with that in PLP. No difference in lysine or methionine digestibility was observed. When digesta were collected in 2-h periods, the apparent ileal digestibility coefficient of amino acids did not change over time. When digesta was collected in 4-h periods from 16:00 to 20:00 and 6-h periods from 14:00 to 20:00 (p<0.05), WLP and CLP showed markedly higher amino acid digestibility than PLPConclusion: High-amylose slowly digested starch can increase the DM flow at the distal ileum and reduce the apparent ileal digestibility coefficient of amino acids of pigs fed LP diets. Compared with waxy corn starch and corn starch, pea starch reduced the digestibility of amino acids in digesta collected after 4 h postprandial.

Background: Salmonella is one of the main foodborne bacterial pathogens, causing diseases and death. The study used reverse transcription loop-mediated isothermal amplification (RT-LAMP) to detect Salmonella. Objectives: To design six primers and detect Salmonella using RT-LAMP to facilitate the rapid detection of pathogenic bacteria in food. Methods: We designed six primers based on the gene coding sequences of inv A, specific to Salmonella. Each reaction solution contained 6.0 mM MgSO4, 1 M betaine, 1.6 mM dNTPs, 160 U/mL Bst DNA polymerase, 0.2 μM of both external primers, 0.8 μM of both internal primers, and 0.2 μM of both loop primers. The reaction temperature was 65°C. Results: Our amplified products were separated by 2% agarose gel electrophoresis. The detection limit was 10 CFU per reaction. Conclusions: RT-LAMP exhibited the same accuracy as the Chinese National Standard assay (GB 4789.30-2016) assay in detecting Salmonella in foods. RT-LAMP was highly specific and sensitive; hence, it may serve as an effective tool in detecting Salmonella.
