Background/Aims
In a recent study, attenuation imaging (ATI) with ultrasound was used as a new approach for detecting liver steatosis. However, although there are many studies on ATI and controlled attenuation parameter (CAP) that prove their practicability, there are few studies comparing these two methods. As such, this study compared CAP and ATI for the detection and evaluation of liver steatosis.

Methods
A prospective analysis of 28 chronic liver disease patients who underwent liver biopsy, FibroScan® imaging, and ATI with ultrasound was conducted. The presence and degree of steatosis, as measured with the FibroScan® device and ATI, were compared with the pathological results obtained using liver biopsy.

Results
The areas under the receiver operating characteristic curve (AUROC) of ATI and CAP for differentiating between normal and hepatic steatosis were 0.97 (95% confidence interval [CI] 0.83–1.00) and 0.96 (95% CI 0.81–0.99), respectively. ATI has a higher AUROC than CAP does in liver steatosis, at 0.99 (95% CI, 0.86–1.00) versus 0.91 (95% CI, 0.74–0.98) in grade ≥ 2 and 0.97 (95% CI, 0.82–1.00) versus 0.88 (95% CI, 0.70–0.97) in grade = 3, respectively.

Conclusion
The ATI and CAP results showed good consistency and accuracy for the steatosis grading when compared with the liver biopsy results. Moreover, ATI is even better than CAP in patients with moderate or severe steatosis. Therefore, ATI represents a non-invasive and novel diagnostic tool with which to support the diagnosis of liver steatosis in clinical practice.

Background and objective
The risk factors for breakthrough infections among healthcare workers (HCW) after completion of a full course of vaccination are poorly understood. Our objective was to determine the risk factors for breakthrough SARS-CoV-2 infection among HCWs at a national healthcare system in Qatar.

Methods
We identified all HCWs at Hamad Medical Corporation in Qatar between December 20, 2020 and May 18, 2021 with confirmed SARS-CoV-2 RT-PCR infection >14 days after the second vaccine dose. For each case thus identified, we identified one control with a negative test after December 20, 2020, matched on age, sex, nationality, job family and date of SARS-CoV-2 testing. We excluded those with a prior positive test and temporary workers. We used Cox regression analysis to determine factors associated with breakthrough infection.

Results
Among 22,247 fully vaccinated HCW, we identified 164 HCW who had breakthrough infection and matched them to 164 controls to determine the factors associated with SARS-CoV-2 breakthrough infection. In the breakthrough infection group the nursing and midwifery job family constituted the largest group, spouse was identified as the most common positive contact followed by a patient. Exposure to a confirmed case, presence of symptoms and all other job families except Allied Health Professionals when compared with nursing and Midwifery staff independently predicted infection.

Conclusion
Presence of symptoms and contact with a confirmed case are major risk factors for breakthrough SARS-CoV-2 infection after vaccination, and these groups should be prioritized for screening even after full vaccination.

Picea obovata Ledeb. is a slow-growing in the early stages of growth type of coniferous trees. The use of growth stimulants in the cultivation of spruce seedlings can accelerate the production of standard planting material. The paper presents the results of research of plant growth regulators influence on spruce seedlings within three years of cultivation in forest nursery conditions. Before sowing seeds of spruce soak in solutions of biological-active preparations Verva and Verva-spruce, obtaining from Abies and Picea wood greenery extracts. The plants growth regulator Verva from Abies needles (operating substance – triterpenic acids) is applied in plant growing at cultivation agricultural and commercial crops. Operating substance of a preparation Verva-spruce used for protection of agricultural plants from diseases, are phenolic compounds of Picea wood greenery possessing fungicidal and insecticidal activity.
It is established that spruce seedlings processed before sowing by bio-preparation had higher parameters of growth (seedling height, diameter of seedling tree at root neck) in comparison with control plants within three years of cultivation in conditions of forest nursery. Three-year spruce seedlings which have been grown up with use of growth stimulators Verva and Verva-spruce exceeded control on 20–30% on height and on 19–20% on seedling tree thickness.
Bio-preparations Verva and Verva-spruce can be recommended for application in forest nurseries as effective growth stimulators at cultivation of Siberian spruce landing material.

Abstract
A 3-year IUPAC project Systems Thinking in Chemistry for Sustainability: Toward 2030 and Beyond (STCS 2030+, IUPAC Project #2020-014-3-050) [1] launched in late 2020 is breaking important new ground in addressing chemistry’s orientations, roles, and responsibilities in the 21st Century and helping to map out implications for chemistry education, research, and practice. In taking on this ambitious task, STCS 2030+ draws on expertise available within IUPAC’s own structures, as a project co-sponsored by three IUPAC standing committees: the Committee on Chemistry Education (CCE), the Committee on Chemistry and Industry (COCI) and the Interdivisional Committee on Green Chemistry for Sustainable Development (ICGCSD). The project is also working with other organizations, such as the International Organization for Chemical Sciences in Development (IOCD), which is a co-supporter, and involves collaborators with individuals from organizations that include the Stockholm Resilience Centre [2], the American Chemical Society (ACS) Green Chemistry Institute [3], the International Year of Basic Sciences for Sustainable Development (IYBSSD 2022-23) [4], and chemistry educators and chemical industry from around the world.
Spielarten spätmittelalterlicher Handschriften
Authors: Schultz-Balluff Simone 
Published: October 2021

Abstract
This paper deals with the communicative sense-making of paratexts, esp. peritextual elements, in pre-modern manuscripts and early prints. First, the theoretical basis of this contribution is outlined, which is situated between Genette’s approach, traditional gloss research, and ‘material philology’. It is based on the idea that each peritextual element has a communicative meaning and accompanies the understanding of the text in an individual way. A comparative analysis of manuscripts and prints of a passion dialogue (14th–16th century) points out how different peritextual entities are used and which communicative offer is made. Finally, the importance of annotating peritextual elements and their visualisation in digital editions is discussed.

Abstract
This study aims to improve the hydrophobic properties and corrosion resistance of fluorinated acrylate coatings. The surface of nano-SiO2 was modified by the silicone coupling reagent (KH-570), and the reactive functional groups were introduced to modify fluorinated acrylates. The functionalized SiO2-modified waterborne fluorinated acrylate emulsion was prepared by free polymerization with dual initiators. The structure of the polymer was analyzed by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectro-meter (1H-NMR), X-ray photoelectron spectroscopy (XPS) and Waters gel chromatography (GPC). The properties of the films and coatings were analyzed by contact angle, atomic force microscopy, scanning electron microscopy, and electrochemical analysis. The results showed that the contact angle reached 120° when the SiO2 content was 3%, the electrochemical impedance value reached 1.49 × 107 Ω·cm2, and the pencil hardness was 3H.
Monetary Policy and Asset Price Gap Signal Technology in a New Keynesian Framework
Authors: Mislin Alexander 
Published: October 2021

Abstract
This article develops a New Keynesian model in which the inflation rate depends on the present value of future output gaps and asset prices gaps. The latter follows a price adjustment process. These asset price gaps are driven by ‛asset price gap signal technology’, a measure of exponentially distributed asset price gaps with a signalling mechanism. Within a dynamic stochastic optimisation approach, I identify a policy rule for the central bank in which the asset price gap the difference between the actual asset price at time t to its fundamental value plays a crucial role in determining the nominal rate of interest.

Abstract
This article present wideband Metamaterial Cross Polarizer (MCP) structure for C and X band applications. The proposed structure consists of wheel shaped associated with meander line and triangular shaped patches having overall dimension of 18 × 18 mm. The anisotropic design patchis a single metallic layer (Cu) placed at the top of dielectric substrate FR-4 and backed by a ground also consists of metal layer (Cu). A wideband Polarization Conversion Ratio (PCR) above 0.8 magnitudes is achieved having bandwidth of 8.1 GHz ranging from 3.43 to 11.53 GHz and it works for C (4–8 GHz) and X (8–12 GHz) band approximately. The bandwidth of PCR at Full Width Half Maxima (FWHM) achieved is 8.24 GHz (3.60–11.84 GHz). Three distinct PCR peaks are observed at 4.2, 5.98, and 9.46 GHz with PCR magnitudes at 91.07, 96.39, and 99.76% respectively. Analysis of polarization conversion phenomena at these three frequencies is described with the help of current and electric field distribution. The proposed anisotropic structure is examined at different angles under normal and oblique incident. The simulation is performed through ANSYS HFSS (19.1), fabrication is done on substrate FR-4 using printed circuit board (PCB). The simulated and measured curves obtained for reflection coefficient and PCR are similar to one another with minute difference due to fabrication tolerances.

Abstract
Low pressure superheated steam drying (LPSSD) is an attractive drying method, which can retain nutrients in fruits and vegetables well. To obtain high quality drying products, it is necessary to understand the main factors affecting the quality attribute of drying sample. Therefore, green turnip was selected as the drying sample and sensitivity analysis method was used to identify the main influencing factors of product quality, such as color, re-hydration performance and Vitamin C during LPSSD. The results showed that the drying temperature had the greatest influence on the color change and vitamin C retention of green turnip. The total color difference ΔE* increased with the elevated drying temperature. The drying pressure had the greatest influence on re-hydration performance and the re-hydration ratio decreased with the elevated drying pressure.

Abstract

Objectives
The aim of the current prospective randomized control study was to assess efficacy, safety, and non-inferiority of a new liquid L-thyroxine formulation dissolved in glycerol and water (T4® drops, produced by a Greek pharmaceutical Company, Uni-Pharma, Athens, Greece) in comparison to the standard Tablets form (T4® tablets, Uni-Pharma, Athens, Greece) in the substitutive treatment of children with congenital hypothyroidism (CH).

Methods
Thirty-nine children with CH, aged 3–12 years old, were enrolled in the study, after parental Informed Consent has been obtained, while three patients were lost from follow-up. At baseline, all participants had normal thyroid-stimulating hormone (TSH) and Free T4 values. Patients were randomly subdivided according to the assigned treatment in Group A (n=17)-Tablet Form and Group B (n=19)-Liquid Form. TSH and Free T4 levels were evaluated at 0, 2, 4, and 6 months.

Results
TSH values showed a statistically significant difference (p=0.017) between groups only at six months (Group A having higher TSH levels than Group B, albeit within the normal range), while Free T4 levels had no statistical difference throughout the six month study period and were always within the normal range. Moreover, dose adjustments were more frequent in Group A (p=0.038) during the six months. Liquid L-thyroxine substitutive treatment exhibited no statistically significant adverse effects in comparison to the widely used tablets.

Conclusions
Levothyroxine (LT4) as liquid solution formulation is safe and noninferior to the widely used L-thyroxine Tablets, with less need for dose adjustment, and can therefore be safely used in the treatment of children with CH.

Published: October 2021

Abstract
During the Fourth Industrial Revolution, the digital transformation revolutionised both individual organisations and entire industries. One such advanced technology is Robotic Process Automation (RPA). However, organisations do not always make the progress by using the RPA to increase the efficiency of their business processes. The scientific sources lack the synthesis of Process Management (PM) and RPA and insights into their interrelationship. This article aims to fill the gap in the systematic analysis of interrelations between PM and RPA from a managerial perspective by identifying less researched areas and formulating insights and recommendations for future research.
Ultra-narrowband and highly-directional THz thermal emitters based on the bound state in the continuum

Published: October 2021

AbstractThe development of novel and cost-effective THz emitters, with properties superior to current THz sources, is an active and important field of research. In this work, we propose and numerically demonstrate a simple yet effective approach of realizing terahertz sources working in continuous-wave form, by incorporating the new physics of bound state in the continuum (BIC) into thermal emitters. By deliberately designing the structure of slotted disk array made of high-resistivity silicon on top of a low index dielectric buffer layer supported by a conducting substrate, a quasi-BIC mode with ultra-high quality factor (∼104) can be supported. Our results reveal that the structure can operate as an efficient terahertz thermal emitter with near-unity emissivity and ultranarrow bandwidth. For example, an emitter working at 1.3914 THz with an ultranarrow linewidth less than 130 MHz, which is roughly 4 orders of magnitude smaller than that obtained from a metallic metamaterial-based thermal emitter, is shown. In addition to its high monochromaticity, this novel emitter has additional important advantages including high directionality and linear polarization, which makes it a promising candidate as the new generation of THz sources. It holds a great potential for practical applications where high spectral resolving capability is required.
Why are the Dragon and the Elephant more Interested Dancing over South Asian Countries?
Authors: Ziaul Islam Md. , Shuwei Wang 
Published: October 2021

Abstract
This paper aimed at examining the growing influence of China and India in South Asian nations. Both China and India have been doing their utmost to consolidate their influence in this sub-continent through economic, political and military deployment. Although Beijing and New Delhi both want to conquer the heart of neighbor state governments; but Beijing’s regional policy primarily focuses on to ensure peace and stability in this region for China’s internal stability, sustainable economic development and for slacking the powers of the West particularly the US. India, on the other hand, believes that China wants to contain it with the name of help to its neighboring countries which in fact has stolen the peace of New Delhi. The mistrust between the two countries has been reached in a high peak after the border conflicts and global pandemic (COVID-19) followed by vaccine diplomacy.
The Influence of historical scripts on contemporary calligraphy and type design
Authors: Ling Manny 
Published: October 2021

Abstract
Traditionally, calligraphers and palaeographers seldom co-operate or collaborate. This is somewhat surprising considering both disciplines deal with the written texts in one form or another. One could argue that if we learn from each other’s respective fields, it would be mutually beneficial and enrich each other’s practice.
This paper discusses the relationship between calligraphy, palaeography, and type design. It focuses on the question of how a calligrapher might approach and analyse a manuscript and how historical scripts have been an inspirational area for contemporary calligraphy and type design. This paper is written from a practitioner’s perspective in describing the processes of how calligraphy is analysed. From looking at manuscripts and documents, what elements can be obtained to develop ideas into design and artwork? What are the processes involved in using both traditional and digital methods? In contemporary calligraphy, what cross-cultural elements can we learn to enrich our traditions? This paper will use examples of my work and that of others as models for discussion.

Published: October 2021

Abstract
The formation of thermally and mechanically induced near-surface microstructures in the form of white layers leads to different hardness properties in these areas. Therefore, this paper conducts systematic surface hardness measurements and uncertainty quantification utilizing the Monte Carlo Method (MCM) in accordance with the Guide to the Expression of Uncertainty in Measurement (GUM). Furthermore, several meta-models describing the hardness course in relationship to the material depth are used to model this nonlinear relationship via machine learning. The evaluation and selection of the optimal model considers the trade-off between measurement uncertainty and prediction quality in terms of mean squared error (MSE). The resulting measurement uncertainty is to be used for the calibration of a non-destructive micromagnetic material sensor. This will then be implemented for in-process monitoring in the outer diameter longitudinal turning process. This should make it possible to detect white layers during machining and to avoid them accordingly by controlling the machine parameters. By means of a soft sensor, the corresponding target value is to be derived from the micromagnetic material sensor measurement.

Published: October 2021

Background and aims. In today’s world, everyone is mindful of one’s appearance and appreciates aesthetics. Of the various restorative materials available, composites are considered as the most aesthetic with good color stability. This study aims at finding the effect of brushing on the color stability of nanohybrid composite after being immersed in various beverages.
Methods. Thirty disk specimens were prepared for each staining solution (N=30), with a total of 90 specimens. The disk specimens for each staining solution were then sub divided into 2 groups (N=15): brushing and non-brushing. After preparation, the specimens were soaked in distilled water for 24 hours in separate containers. Baseline color of the samples was evaluated using spectrophotometer. The samples were then immersed in tea, coffee or water. The groups of samples to be brushed were held in the mold and 20 strokes of brushing using an electronically powered toothbrush were done on each side of the disk sample. The color was re-evaluated after a period of 14 days.
Results. When comparing among the three beverages, tea showed the highest ΔE*ab indicating greatest discoloration when compared to coffee and water. This can be graded as tea > coffee > water. However, statistically there was no significant difference between tea and coffee. When compared within tea, coffee, or water specimens the non - brushed specimens showed greater discoloration compared to the brushed specimens both clinically and statistically.
Conclusion. When immersing the specimens in the solutions, tea showed more color change compared to coffee, making the specimens clinically unacceptable. However, brushing the specimens reduced the discoloration when compared to non–brushing, making the coffee specimens clinically acceptable.
