Abstract:

Aims and objectives/purpose/research questions: The study examines bilingual children’s prosodic competence, specifically the ability to correctly assign word stress in both languages, and contrasts it with participants’ segmental competence. To this end, we estimated and compared the magnitude of prosodic and segmental transfer in L1 and L2 speech of typically developing Polish–English migrant bilingual children raised in the UK. We also explored the influence of cumulative language exposure on both types of transfer. Design/methodology/approach: A non-word repetition task was used in both languages to assess children’s faithfulness in repeating segmentals and stress patterns in two to five syllable-long items. Also, a parental questionnaire on cumulative language exposure was conducted to estimate the quality of input in both languages. All children ( N = 59, M = 5;8) were early bilinguals raised in the UK. Data and analysis: A 2x2 ANOVA and a correlation analysis were conducted to compare the magnitude of prosodic and segmental transfer, within and across languages. Also, multiple regression analysis was performed to establish the predictors of transfer in L1 and L2. Findings/conclusions: The bilingual children repeated stress patterns in both languages correctly, showing resistance to transfer in word stress, even though bidirectional transfer was observed in segmentals. The magnitude of segmental transfer in Polish and English was predicted by cumulative exposure to English, while prosodic transfer in Polish was predicted by cumulative exposure to Polish. Originality and significance/implications: The study provides evidence on word stress placement in the age group of bilingual children, 4–7 years of age, in comparison with segmental data. It uses a novel methodology in comparing the magnitude of transfer between prosody and segmentals, within and across languages. Moreover, the study highlights the importance of language exposure for reducing the amount of segmental transfer in this group of children.

Abstract:

AbstractThe sequential segmental approach is now universally used in the diagnosis of congenital heart disease. Its utilization during fetal sonography has not been well described. In this review, we show how the fetal heart can be approached in a sequential segmental manner by using six basic sonographic views. The transverse view of the fetal upper abdomen is obtained to determine the arrangement of the abdominal organs, which, in most cases, provides the important clues to the determination of the atrial arrangement. The four-chamber view is obtained to evaluate the atrioventricular junctions. The views of the left and right ventricular outflow tracts are obtained to evaluate the ventriculoarterial junctions. The three-vessel view and the aortic arch view are obtained for the evaluation of the arrangement and size of the great arteries, which provides the additional clues to the diagnosis of the abnormalities involving the ventriculoarterial junctions and the great arteries. The standard protocol to acquire these six basic views is also introduced.

Abstract:

Abstract Context.—Diffuse thinning of the glomerular basement membrane (GBM) is the ultrastructural diagnostic criterion of thin basement membrane nephropathy (TBMN). However, there is no consensus regarding what diagnosis should be made if the attenuation is segmental. Objective.—To develop a diagnostic approach to TBMN in cases with segmental GBM thinning. Design.—We compared the diagnostic sensitivities of 2 methods used for the quantitative expression of GBM width in a consecutive series of renal biopsies from 26 patients (median age, 36 years; range, 15 to 59 years) with dysmorphic hematuria (a variable degree of proteinuria in 19 patients), a thin GBM, and absence of other renal disease. The harmonic GBM width was determined from orthogonal intercepts, and the actual width in the thinnest loops was obtained by direct measurement. The GBM attenuation was categorized into diffuse or segmental types by conventional inspection. Results.—Segmental TBMN accounted for one third of the series. In neither type did the male patients have a higher harmonic mean GBM width than the female patients. Focal-global glomerulosclerosis was more common in diffuse TBMN. The laborious orthogonal intercept method proved insensitive for the verification of segmental TBMN, whereas the much simpler direct measurement technique captured all the cases. Conclusions.—A considerable number of patients with TBMN display segmental GBM attenuation. Because the routine criterion excludes these cases from the diagnosis, we propose to define TBMN as a clinicopathologic entity of dysmorphic hematuria and a diffusely or segmentally thinned GBM confirmed by the direct measurement technique.

Abstract:

AimsStrain artefacts are known to hamper the correct interpretation of segmental strain and strain-rate (S/SR). Defining the normal ranges of myocardial segmental deformation is important in clinical studies and routine echocardiographic practice. In order to define artefact-free normal ranges for segmental longitudinal S/SR parameters, we investigated the extent to which different types of artefacts and their segmental localisation in the three different myocardial layers created a bias in the results of echocardiographic strain measurements.MethodsThe study included echocardiograms from men and women aged 40–69 years from two population-based studies, namely the Know Your Heart study (Russia) and the Tromsø Study (Norway). Of the 2207 individuals from these studies, 840 had normal results, defined as the absence of hypertension or indicators of any cardiovascular disease. Two-dimensional (2D) global and segmental S/SR of the three myocardial layers were analysed using speckle tracking echocardiography. Artefacts were assessed with two different methods: visual identification of image-artefacts and a novel conceptual approach of ‘curve-artefacts’ or unphysiological strain-curve formation.ResultsSegmental strain values were found to have significantly reduced in the presence of strain-curve artefacts (14.9%±5.8% towards −20.7%±4.9%), and increased with the foreshortening of the 2D image. However, the individual global strain values were not substantially altered by discarding segmental artefacts. Reduction due to artefacts was observed in all segments, layers, systolic and diastolic strain, and SR. Thus, we presented normal ranges for basal-septal, basal, medial and apical segment groups after excluding artefacts.ConclusionStrain-curve artefacts introduce systematic errors, resulting in reduced segmental S/SR values. In terms of artefact-robust global longitudinal strain, the detection of curve-artefacts is crucial for the correct interpretation of segmental S/SR patterns. Intersegmental S/SR gradients and artefacts need to be considered for the correct definition of normalcy and pathology.

Abstract:

The detection of chromosomal aneuploidies and mosaicism degree in preimplantation embryos may be essential for achieving pregnancy. The aim of this study was to determine the robustness of diagnosing homogenous and mosaic aneuploidies using a validated algorithm and the minimal resolution for de novo and inherited deletions and duplications (Del/Dup). Two workflows were developed and validated: (a,b) preimplantation genetic testing for uniform whole and segmental aneuploidies, plus mixtures of euploid/aneuploid genomic DNA to develop an algorithm for detecting mosaicism; and (c) preimplantation genetic testing for structural rearrangements for detecting Del/Dup ≥ 6 Mb. Next-generation sequencing (NGS) was performed with automatic library preparation and multiplexing up to 24–96 samples. Specificity and sensitivity for PGT-A were both 100% for whole chromosomes and segmentals. The thresholds stablished for mosaicism were: euploid embryos (<30% aneuploidy), low mosaic (from 30% to <50%), high mosaic (50–70%) or aneuploid (>70%). In the PGT-SR protocol, changes were made to increase the detection level to ≥6 Mb. This is the first study reporting an accurate assessment of semiautomated-NGS protocols using Reproseq on pools of cells. Both protocols allow for the analysis of homogeneous and segmental aneuploidies, different degrees of mosaicism, and small Del/Dup with high sensitivity and specificity.

Abstract:

Based on the segmental joint tests, it was found that the practical range of joint flexural rigidity was in range of 8500-29000kN•m/rad. A simplified method for determining the stiffness reduction factor of tunnel lining() was proposed using results from the segmental joint tests in which some parameters were obtained by calibration against a 3D Numerical analysis. The influence of joint flexural rigidity, soil resistance coefficient, thickness of tunnel lining and tunnel calculation radius on the stiffness reduction factor of tunnel lining was examined. The stiffness reduction factor can be simply expressed as a function of joint flexural rigidity ratio, soil resistance coefficient, thickness of tunnel lining and tunnel calculation radius for the typical tunnel lining.

Abstract:

Purpose This paper aims to investigate the fluid flow and heat transfer of a laboratory shell and tube heat exchanger that are analyzed using computational fluid dynamic approach by SOLIDWORKS flow simulation (ver. 2015) software. Design/methodology/approach In this study, several types of baffle including segmental baffle, butterfly baffle, helical baffle, combined helical-segmental baffle, combined helical-disk baffle and combined helical-butterfly baffle are examined. Two important parameters as the heat transfer and pressure drop are evaluated and analyzed. Based on obtained results, segmental baffle has the highest amount of heat transfer and pressure drop. To assess the integrative performance, performance coefficient defines as “Q/Δp” is used. Findings This investigation showed that among the presented baffle types, the heat exchangers equipped with disk baffle has the highest heat transfer. In addition, in the same mass flow rate, the performance coefficient of the shell and tube heat exchanger equipped with helical-butterfly baffle is the highest among the proposed models. Originality/value After combined helical-butterfly baffle the butterfly baffle, disk baffle, helical-segmental baffle and helical-disk baffle show their superiority of 35.12, 25, 22 and 12 per cent rather than the common segmental baffle, respectively. Furthermore, except for the combined helical-disk baffle, the other type of combined baffle have better performance compare to the basic configuration (butterfly and segmental baffle).

Abstract:

Prone transpsoas lateral lumbar interbody fusion is the newest frontier in surgical approach to the lumbar spine. Prone positioning facilitates segmental lordosis and facile posterior segmental fixation. However, even in experienced hands, transitioning from a lateral decubitus to prone position necessitates alterations to the traditional technique. In this video, the authors highlight the nuances of adopting the prone transpsoas lateral lumbar interbody fusion technique and strategies to overcome them.

Abstract:

Background: Segment-oriented liver resections can be performed effective by posterior intrahepatic approach. A significance of such resection is that they are oncologically radical as well as parenchyma- sparing. Methodology: Segmental liver resections were performed in 102 patients with liver tumors. Suprahilar control of the appropriate glissonean pedicle was achieved by the posterior intrahepatic approach. Liver parenchyma was transsected by ultrasonic dissector, under intermittent vascular occlusion (IVO). Pedicle was divided at the end of resection using "endo-GIA" vascular stapler. Results: The overall transection time was 30,14+12,56 min. The amount of blood loss was 285,59+129,92 ml. The postoperative complication rate was 25,49%. R0 resection had 94 (92,16%) patients. There was no liver failure or perioperative death. Conclusions: Posterior intrahepatic approach for segmental resection is safe, can expedite the liver transection and reduce intraoperative hemorrhage. This approach provides adequate tumor clearance with preservation of normal parenchyma, as well as the vasculature or the biliary drainage of the contralateral liver.

Abstract:

A significant number of proteins possess sizable intrinsically disordered regions (IDRs). Due to the dynamic nature of IDRs, NMR spectroscopy is often the tool of choice for characterizing these segments. However, the application of NMR to IDRs is often hindered by their instability, spectral overlap and resonance assignment difficulties. Notably, these challenges increase considerably with the size of the IDR. In response to these issues, here we report the use of sortase-mediated ligation (SML) for segmental isotopic labeling of IDR-containing samples. Specifically, we have developed a ligation strategy involving a key segment of the large IDR and adjacent folded headpiece domain comprising the C-terminus of A. thaliana villin 4 (AtVLN4). This procedure significantly reduces the complexity of NMR spectra and enables group identification of signals arising from the labeled IDR fragment, a process we refer to as segmental assignment. The validity of our segmental assignment approach is corroborated by backbone residue-specific assignment of the IDR using a minimal set of standard heteronuclear NMR methods. Using segmental assignment, we further demonstrate that the IDR region adjacent to the headpiece exhibits nonuniform spectral alterations in response to temperature. Subsequent residue-specific characterization revealed two segments within the IDR that responded to temperature in markedly different ways. Overall, this study represents an important step toward the selective labeling and probing of target segments within much larger IDR contexts. Additionally, the approach described offers significant savings in NMR recording time, a valuable advantage for the study of unstable IDRs, their binding interfaces, and functional mechanisms.

Abstract:

Purpose: The purpose of this study was to determine the ability of noninvasive imaging methods to localize focal liver lesions to specific hepatic segments. Material and Methods: In a prospective study we evaluated 24 patients with hepatic masses with ultrasonography (US), spiral CT and MR imaging. Results: The primary segmental location of the lesions was correct with US in 15 of 24 patients (63%), with CT in 21 of 24 patients (88%) and with MR imaging in 17 of 22 patients (77%). The full extent of the lesions was correctly described with US in 9 of 24 patients (38%), with CT in 16 of 24 patients (67%) and with MR in 12 of 22 patients (55%). Conclusion: Among the noninvasive imaging methods, CT provides the best information for determining the segmental location and planning the surgical approach to hepatic resections.

Abstract:

The prevalence of segmental testicular infarction is extremely uncommon and very few cases have been reported in literature. Clinical and sonographic presentation of this condition can mimic testicular neoplasms or testicular torsion. Therefore, accurate diagnosis of segmental testicular infarction is imperative in the treatment process. This case study presents the sonographic diagnosis of testicular infarction in a 49-year-old man who reported mild testicular tenderness. A conservative treatment approach was used, saving the patient unnecessary surgical intervention.

Abstract:

Purpose – The purpose of this paper is to explore the perceptions of external auditors, preparers and users (investors and analysts) of financial statements in Jordan about this new segmental reporting standard; a decision usefulness framework underpins the research. Design/methodology/approach – The objective of this study is to explore the perceptions of external auditors, preparers and users (investors and analysts) of financial statements in Jordan about this new segmental reporting standard; a decision usefulness framework underpins the research. Findings – The findings reveal that a majority of interviewees found that IFRS 8 was not a problematic standard, and that the management approach of IFRS 8 was an improvement on the previous standard – International Accounting Standard (IAS) 14R – because the information produced was seen as useful to users of financial statements. Moreover, the respondents indicated that there was an improvement in the quantity and quality of segmental information under IFRS 8 in annual reports for 2009; it was more understandable, relevant, reliable and comparable than the segmental information which had previously been reported. Research limitations/implications – No attempt was made to assess the usefulness of segmental information reported under IFRS 8 by Jordanian listed companies in their annual reports for other groups such as lenders, suppliers, customers, trade creditors and the general public (IASC, 1989). Thus, a survey about the impact of IFRS 8 on other groups may yield further insights about the decision usefulness of the new standard’s disclosures. However, Jordanians are not familiar with such research instruments and the culture within the society is relatively secretive (Piro, 1998). Practical implications – The findings of the current research should be valuable for international accounting standard setters at the International Accounting Standards Board. It provides some indication about the impact of this new standard. Originality/value – This research shows that segmental information reported under IFRS 8 is more useful for decision makers needs compared to segmental information that previously reported under IAS 14R. It also provides a great insight about the impact of this new segmental disclosure standard.

Abstract:

Abstract Introduction. T2* measurement of myocardial iron overload (MIO) is presently the gold standard for monitoring and tailoring the chelation in thalassemia patients. Native T1 mapping has been proposed also for the MIO quantification because it is known that iron can reduce native T1 values. No data are available in literature comparing T1 and T2* mapping using a segmental approach including the whole left ventricle. The goal of our study was to assess the relationship between T1 and T2* values using a segmental approach. Methods. 29 patients with hemoglopinopathies (18 females, 45.39±13.49 years) enrolled in the Extension Myocardial Iron Overload in Thalassemia (eMIOT) Network were considered. Native T1 and T2* images were acquired, respectively, with the Modified Look-Locker Inversion recovery (MOLLI) and with the multi-echo gradient-echo techniques. Three parallel short-axis views (basal, medium and apical) of the left ventricle (LV) were acquired with ECG-gating. The myocardial T1 and T2* distribution was mapped into a 16-segment LV model, according to the AHA/ACC model. The lower limit of normal for each segment was established as mean±2 standard deviations on data acquired on 14 healthy volunteers. In 25 patients also post-contrastografic images were acquired. Results. T1 images showed more pronounced motion artifacts and lower contrast-to-noise-ratio, determining the exclusion of 18/464 segments. No segments were excluded by T2* mapping. So, globally, 446 segmental T1 and T2* values were considered. The mean of all segmental T2* and T1 values were, respectively, 37.83±11.30 ms and 982.72±118.24 ms. Normal T2* and T1 values were found in 374 segments (83.9%) while 29 (6.5%) segments had pathologic T2* and T1 values. For 33 segments (7.4%) (13 patients) a pathologic T1 value was detected in presence of a normal T2* value. For 10 segments (2.2%) a pathologic T2* value was detected in presence of a normal T1 value. Out of the 9 patients with pathologic T2* values in presence of normal T1, in 7 patients post-contrastografic images were acquired; in all segments with pathologic T2* value macroscopic fibrosis by late gadolinium enhancement technique and/or microscopic fibrosis by T1 mapping were found. The relation between segmental T1 and T2* values is shown in the figure. For patients with pathologic segmental T2* values there was a linear relationship between T1 and T2* values (R=0.735, P<0.0001) while the whole data was fitted with a quadratic curve. Conclusion. T2* and T1 mapping showed a good correlation in identifying iron by a segmental approach. However, we found a scatter between results. In 9 patients T1 mapping was not able to detect iron probably due to the presence of macroscopic and/or microscopic fibrosis that it is known to increase the native T1 . Conversely, in 13 patients T1 mapping seems to be more sensitive than T2* (sensitive to different iron chemistry or error measurements?). Further studies on larger population and correlation with clinical outcome are need. Figure. Figure.

Abstract:

Purpose The purpose of this paper is to examine the extent of segmental reporting disclosure and its value relevance to a sample of Qatari and Jordanian listed companies following the implementation review of the International Financial Reporting Standard (IFRS) 8. This was the first standard to be subjected to a post-implementation review. Annual reports are initially analyzed to investigate the level of segmental information that was published by companies in these two countries. Design/methodology/approach Using the Ohlson (1995) model, the study employs regression analysis to test the hypotheses relating to the value relevance of the segmental disclosures uncovered. In addition, one-way ANOVA and Kruskal-Wallis tests are used to investigate any variation in segmental reporting among sectors. Findings The findings indicate that the amount of segmental information disclosed by the sample firms differs across sectors. Moreover, the segmental information provided (including the number of segments and the amounts of disclosure) is value relevant and can explain the variations in firms’ share prices. Practical implications The results of the current investigation have implications for policy makers, including the International Accounting Standards Board, as well as for accounting regulators in Jordan and Qatar. They suggest that the segmental disclosures supplied under IFRS 8 are value relevant for equity prices in a developing country context. Compliance with IFRS 8 should thus be monitored to ensure that all firms provide the segmental disclosures that they are meant to supply under the terms of the standard. Originality/value This paper is one of the few to provide empirical evidence on the role of segmental reporting following the post-implementation review that was conducted for IFRS 8.
