AbstractThe objective of this article was to study the reproducibility and reliability of the fetal corpus callosum measurements between two-dimensional (2D) and three-dimensional (3D) acquisitions. This prospective study enrolled 475 fetuses, monitored between 18 and 38 weeks of gestation by two operators. Starting from a transcerebellar axial plane, 3D and 2D mid-sagittal views of the corpus callosum were obtained. Measurements of length and thickness were performed and underwent quality control by independent reviewers. The acquisition time of the two methods was measured. Means, differences, and linear correlations were analyzed using t-test, regression and Pearson's correlation coefficients, and Bland–Altman's plots. This analysis was performed for each operator to test the interobserver reproducibility. Among the 432 cases measured using both methods, 380 (88%) were validated by quality control. The mean corpus callosum length and thickness were essentially the same using 2D and 3D measurements (2D: 33.8 ± 8.7 vs. 3D: 33.7 ± 8.7 mm, 2D: 2.2 ± 0.4 vs. 3D: 2.2 ± 0.4 mm, respectively; mean ± standard deviation [SD]). Linear regression coefficients and Pearson's coefficients were similar for length (2D: 0.8283 and 0.9191 vs. 3D: 0.8271 and 0.9095), but slightly different regarding thickness (2D: 0.6775 and 0.8231 vs. 3D: 0.5831 and 0.7636). Differences between 2D and 3D measurements, considering Bland–Altman's plots and correlated with gestational age, were acceptable (2D: 0.097 ± 0.559 mm, 3D: 0.004 ± 0.111 mm). The acquisition time required was significantly lower for 3D acquisitions (3D: 25.2 ± 14.5 seconds vs. 2D: 35.1 ± 19.4 seconds, p < 0.01). Linear regression and Pearson's coefficients for the measurements of corpus callosum length and thickness using 2D or 3D acquisitions did not differ between the operators. This study confirmed good reproducibility of corpus callosum assessment by transabdominal 3D acquisitions. The good feasibility in routine scans may lead to better screening for callosal dysgenesis.

AbstractCeliac disease (CD) is an autoimmune enteropathy in the small intestine caused by gluten intolerance of the patients. The most important genetic disease-related factor is human leukocyte antigen (HLA)-DQ polymorphism. Association between interleukin (IL)-17A expression of CD4+ T cells and various autoimmune diseases has been reported. The aim of this study was to investigate the relationship between single nucleotide polymorphism (rs2275913) IL-17A and HLA-DQ polymorphisms in Turkish pediatric celiac patients. Study group included 125 pediatric celiac patients with CD and 100 healthy pediatric controls. Deoxyribonucleic acid was isolated from peripheral blood samples. IL-17A polymorphism (rs2275913) was analyzed by polymerase chain reaction-restriction fragment polymorphism method. IL-17A polymorphism and low-/high-resolution HLA-DQ results of patients were evaluated. GG and GA genotype frequencies of IL-17A (rs2275913) polymorphism were significantly higher (p < 0.05) in the CD patients than the control group. HLA-DQB1*02 and HLA-DQA1*05 alleles were detected in patients, while HLA-DQB1*03 and HLA-DQA1*01 alleles in the control group. Also, when we compared the patient and control groups in terms of HLA-DQ-DR haplotypes, HLA-DQB1*02-DQA1*05-DRB1*03 was found with the relative risk of 42.5 (p < 0.05). As a result of high-resolution HLA-DQB1 typing, DQB1*02:01 and DQB1*03:02 were at high frequency (p < 0.05; in 25 patient group). IL-17A (rs2275913) polymorphism genotype frequency was found to be significant in the patient group compared with the control group. The most common HLA-DQB1 suballele was observed as DQB1*02:01.

Published: February 2021

Abstract
Background Computed tomography pulmonary angiography (CTPA) is the imaging modality of choice for the diagnosis of acute pulmonary embolism (PE). With computed tomography pulmonary perfusion (CTPP) additional information on lung perfusion can be assessed, but its value in PE risk stratification is unknown. We aimed to evaluate the correlation between CTPP-assessed perfusion defect score (PDS) and clinical presentation and its predictive value for adverse short-term outcome of acute PE.
Patients and Methods This was an exploratory, observational study in 100 hemodynamically stable patients with CTPA-confirmed acute PE in whom CTPP was performed as part of routine clinical practice. We calculated the difference between the mean PDS in patients with versus without chest pain, dyspnea, and hemoptysis and 7-day adverse outcome. Multivariable logistic regression analysis and likelihood-ratio test were used to assess the added predictive value of PDS to CTPA parameters of right ventricle dysfunction and total thrombus load, for intensive care unit admission, reperfusion therapy and PE-related death.
Results We found no correlation between PDS and clinical symptoms. PDS was correlated to reperfusion therapy (n = 4 with 16% higher PDS, 95% confidence interval [CI]: 3.5–28%) and PE-related mortality (n = 2 with 22% higher PDS, 95% CI: 4.9–38). Moreover, PDS had an added predictive value to CTPA assessment for PE-related mortality (from Chi-square 14 to 19, p = 0.02).
Conclusion CTPP-assessed PDS was not correlated to clinical presentation of acute PE. However, PDS was correlated to reperfusion therapy and PE-related mortality and had an added predictive value to CTPA-reading for PE-related mortality; this added value needs to be demonstrated in larger studies.
Indocyanine Green Use in the Minimally Invasive Gastrointestinal Surgery
Authors: Ferri Francisco A. , Szomstein Samuel 
Published: February 2021

AbstractIndocyanine green (ICG) is a fluorescent dye that has been used in some medical specialties already for almost 60 years and has gained popularity in recent years due to the clinical applications recently proposed in the surgical field. This review article details the current use of the ICG in the minimally invasive gastrointestinal surgery. There is abundant evidence validating the usefulness of ICG fluorescence angiography in the gastrointestinal surgery, leading to a decrease of complications. Other uses, such as its lymphographic use for sentinel lymph node mapping or detection of metastatic lymph nodes, need further investigation to prove its benefit. The heterogeneity and subjective nature of the data remain the greatest challenge when analyzing the possible effects ICG can bring to the gastrointestinal surgery.
Electron dissipation after radio-frequency discharge burst at atmospheric pressure
Authors: Han Qianhan , Guo Ying , Zhang Yarong , Zhang Jing , Shi J. J. 
Published: February 2021

The discharge characteristics and mechanism of pulse modulated radio frequency (RF) atmospheric pressure glow discharge (APGD) are studied using a two-dimensional self-consistent numerical fluid model. The ignition of an RF discharge burst is demonstrated by the increase in RF current amplitude and evolution of the discharge spatial profile from a bell shape to a double-hump shape. With a time interval of 80 µs between two consecutive RF discharge bursts, the electron dissipation after an RF discharge burst is shown, whose reduction slope changes from 1.7 × 1022 m−3s−1 to 9.1 × 1019 m−3s−1 with a time delay. The corresponding electron dissipation mechanism is proposed to be the electron loss due to reactions in the discharge bulk and the drift of electrons across the discharge gap, which explains the continuum and discrete operation modes in pulse modulated RF APGD.

Published: February 2021

Significance
Many mammals with frontal eyes have robust binocular vision and stereoscopic depth perception. Here, we show that the organization of projections from the retinas to the central nervous system in these animals is quite effective in ensuring that the most common binocular disparities send signals directly to the same cortical hemisphere, thereby enabling fast and accurate depth estimation.
An enhanced sparse filtering method for transfer fault diagnosis using maximum classifier discrepancy

Published: February 2021

Abstract
The speed of rotating parts is often affected by different working conditions in mechanical equipment, which results in more complications in the feature mapping relationship. However, existing methods that address the large fluctuation problem in rotational speed have been formulated merely to improve test accuracy and do not consider the effects of irregular fluctuation frequency on the fault samples located at the class boundary. Thus, to distinguish the health conditions under frequent or irregular fluctuation speeds, this paper explores an enhanced sparse filtering (SF) algorithm based on maximum classifier discrepancy to diagnose the fault conditions caused by speed fluctuation. It considers the superiority of the task-specific decision boundary and adversarial training for the fault diagnosis network. Unlike traditional SF methods, the proposed framework introduces the Wasserstein distance to reduce the domain discrepancy between the source domain and the target domain and then uses the probability output discrepancy of the classifier to locate the fuzzy fault samples on the class boundary. This paper conducts theoretical analysis and experimental comparison and verifies the performance advantages of the framework through bearing and gear experiments under large speed fluctuation conditions. The proposed model also shows an excellent performance even when the speed fluctuates frequently.
Rectification, transport properties of doped defective graphene nanoribbon junctions

Published: February 2021

Abstract
The transport properties and rectification behavior of junctions which contain armchair graphene nanoribbons (AGNRs) with double vacancy defects or nitrogen-doped in three different sizes of 9, 10 and 12 atoms are studied. The non-equilibrium Green function method and density functional based tight-binding approach are used for different computations. The double vacancy (DV) defects are along the direction of current pathways of graphene devices. We calculated transmission probability, density of states, the current–voltage curves, rectification ratio, and electrodes band structures. We found that I–V graph has nonlinear characteristic and displays rectification behavior. Devices which posses the size of 9 atoms show significant sign of rectification in contrast to other cases (10, 12 atoms). But the current value is more important for the device of 12 atoms size. Moreover, it is shown that extra energy bands are created by the DV defects and nitrogen (N) doped atoms. These bands of DV defects and N-doped cause the Fermi level to shift upwards and can change the behavior (n-type semiconductor, or metal-like) of devices of 9, 10 and 12 AGNRs. Also, various orbital distributions of MPSH (molecularly projected self-consistent Hamiltonian) states in the DV-9AGNR device are investigated.

To describe the evolution of various quantum states, we use a Hubbard based model and Lindblad formalism. The suggested optimization algorithm uses the time evolution of entanglement entropy and mutual information for the determination of the system parameters to achieve high fidelity gates.

Abstract
With the development of major engineering such as offshore deep-water ports, marine energy exploitation and open sea reefs, ocean engineering has gradually distracted its attention from coastal areas to offshore areas of open seas. Offshore construction faces unfavourable challenges including severe weather conditions, great difficulty in construction and high cost in project scheduling. It is important to organize the process in an efficient way during the operation window for ships. In this study, physical model tests are conducted to investigate the motion characteristics of large-scale construction ships. Based on the field data of certain sea area, statistical analysis are performed to find the suitable operational conditions for the ships. The results show that auxiliary measures of seakeeping improvement can be taken to short the non-operational time of the ship and extend the operation window of ships.

Influence of Environmental Conditions and Paving Methods on the Cooling Process of Newly Paved Asphalt Pavement
Authors: Chen J.Z. , He L. 
Published: February 2021

Abstract
A newly laid repaired asphalt pavement must be cooled sufficiently before opening to traffic. By using the finite element simulation model, this paper simulates and analyses the temperature distribution during the cooling process of the repaired asphalt layer under different weather conditions, wind speeds and paving methods, and puts forward some suggestions for the determination of the traffic opening time. The results show that when the surface temperature of the repaired pavement drops to the temperature required by the specification, the internal temperature is still higher than the surface temperature. Simply determining the time of opening traffic according to the road surface temperature will cause premature destruction of the asphalt layer. This situation can be avoided when the internal temperature of the repaired asphalt layer is used as the guide for traffic opening. It is easier to meet the requirements of opening to traffic when paving at night. Compared with single-layer paving strategy, the internal temperature of the pavement drops faster under double-layer paving strategy, but the difference is not so obvious.

Published: February 2021

Abstract
Many contemporary fashion designers show Christian Dior and Cristobal Balenciaga as their inspirators and teachers. Many designers present contemporary interpretation of forms of parts and silhouettes of designs of Dior and Balenciaga. But forms of pieces have to be studied not only as separate elements of design. It is important that they have to be investigated on the base of connections between them. An investigation of shaping in designs of both designers on the base connections between forms of parts, and between forms of parts and silhouettes is presented in the paper. The results of the study of shaping in design of Christian Dior and Cristobal Balenciaga, obtained by correspondence analysis, can be used in fashion design education and by fashion designers in their creative work. This is especially important for young designers in the process of development of their style and creative ideas.

Published: February 2021

Abstract
A fit evaluation can be conducted to determine a clothing is good or not in terms of concrete criteria such as the appearance, the comfort, etc.. However, the existing criteria are still inadequate in predicting the clothing fit in virtual reality and providing numeric recommendations. This research is aimed to develop the criteria of fit evaluation for men’s shirt with regard to body measurements, 2D pattern block, 3D virtual fitting and shirt photos. The databases of consumer’s opinions about misfit of men’s shirt and real try-on photos were first established based on the online resources. Derived from the well-fitted customized pattern block, the variant pattern blocks with estimated reasons of misfit were generated by gradually change the responsible indexes. The specific criteria for different shirt segments were determined by integrating the fit level, real photos, virtual images, body measurements and pattern block. The developed criteria can be not only used for exactly evaluating the fit of sewed shirt, but also for predicting the fit and providing numeric recommendations.

Storing Dynamical Data Using Natural Language Addressing
Authors: Ivanova Krassimira Borislavova 
Published: February 2021

Abstract
The present paper refers to the possibilities for storing dynamical data from tracking moving objects. The urgency of this problem is determined primarily by the need for electronic registration, storage and processing of large volumes of semi-structured dynamical data in various fields of practice. The new problem raised, is the way in which the relationships between the data are described. The capabilities of modern relational database management systems do not allow rapid readjustment in accordance with the changes in practice. The emergence of new types of data connections requires readjustment, which takes time and requires a certain level of skill. In this article we consider an approach based on “Natural language addressing”, which allows solving these problems and we will offer a conceptual design (prototype) of an extension to existing systems, which facilitates the work, especially with dynamical semi-structured data and implicit relationships between them.
