Nytt medium, andre skriftmøte? Skrift som modalitet i fire digitale remedieringar av ei trykt bildebok
Authors: Vadstein Anne Marta Vinsrygg 
Published: October 2024

Trykte bildebøker kan remedierast og publiserast digitalt, noko som inneber at dei meiningsberande ressursane, slik som skrifta og bilda, blir tilpassa det nye mediet. Bildebøker er kjende literacyartefaktar (Hamilton, 2000) i barnehagen, og det er derfor relevant å sjå på om digitale remedieringar gir andre føresetnader for barns tidlege møte med skriftspråket enn den trykte boka gir. Studien byggjer på Gunther Kress og Theo Van Leeuwen (1996, 2021) sin teori om informasjonslenking og analyserer skrifta som modalitet i fire ulike digitale variantar av bildeboka En fisk til Luna (Aisato, 2014). Tekststudien viser at dei digitale produsentane gjer tilpassingar som påverkar skrifta si funksjonelle tyngde både i forteljinga og i paratekstane (Genette, 1997): gjennom skriftmarkering, ved å ta vekk skrifta, endre plasseringa og innramming, eller ved å leggje til trykkefelt med ordbilde. Bakgrunnen for studien er at barn får erfaringar med språk og skrift gjennom å delta i sosiale praksisar med tekstar, som til dømes bildebøker (Snow, 2006, ss. 3–4). Studien diskuterer kjenneteikn ved skriftmodaliteten i dei fire ulike digitale versjonane, kva haldningar til skrift som meiningsberande modalitet dei kan vere uttrykk for, og kva for implikasjonar bruken av desse bøkene kan ha for barnehagen.
ENGLSISH ABSTRACT
New Medium, Different Writing Encounters? Writing as Modality in Four Digital Remediations of a Printed Picture Book
When printed picture books are adapted for digital publication, meaningful resources such as written text and images are modified to fit the new medium. This text study, based on Gunther Kress and Theo Van Leeuwen’s social semiotic theories (1996, 2021), examines the writing modality in four different digital versions of the picture book A Fish for Luna (Aisato, 2014). Children experience language and written texts through participation in literacy practices (Snow, 2006, pp. 3–4), and picture books are recognized as familiar literacy artefacts (Hamilton, 2000) in Early Childhood Education and Care (ECEC). Therefore, it is relevant to discuss whether adapted digital books provide different encounters with the writing modality for the target group than the printed book does. The study shows that the digital producers make adjustments that affect the functional weight of the writing modality in both the narrative and the paratexts (Genette, 1997). These adjustments include marking, removing written text, changing the position and framing, or adding hotspots with word pictures. The study identifies characteristics of the writing modality in the four digital versions and how they express different views on writing as a semiotic resource. It then discusses possible implications for literacy practice in ECEC.

Published: October 2024

Tissue culture is useful as a way to obtain seeds in large quantities of seedlings in a short time as an effort to preserve Bucephalandra sp. in nature. The use of PGR has problems such as expensive prices and difficult to find, therefore its use can be replaced by natural PGR that are easy to obtain and have relatively cheap prices such as coconut water. The aim of this research was to determine the effect of Benzylaminopurine (BAP) and coconut water on the growth of Bucephalandra sp. in vitro. This research is a 2-factor factorial experiment using a completely randomized design. The factors are concentration of BAP (0; 1; 3; 5 mg/l) and concentration of coconut water (0; 50; 100 ml/l). The results showed Murashige and Skoog (MS) media with the addition of BAP 1 mg/l + coconut water 50 ml/l (4.11 shoots), BAP 5 mg/l + coconut water 50 ml/l (4.33 shoots), and BAP 3 mg/l (6.22 shoots) were able to provide the number of shoots with high results. The addition of coconut water did not affect the growth of Bucephalandra sp. MS media can grow shoots with the best results in measurements of shoot emergence time, number of roots, shoot and root length.

The objective of this research is to determine the impact of temperature gradients and solvent ratios in the evaporative vacuum cooling method on the yield of phenol and flavonoid content in galangal extract; ascertain the impact of these factors on the yield generated by galangal extract; and ascertain the mass balance analysis of materials are the objectives of this study. Throughout the extraction of galangal. The study's findings demonstrated that the evaporative vacuum cooling technique, conducted at 49 ºC and with a 1:1 solvent ratio of 1.4432±0.7317 mg GAE/g, produced the highest total phenol concentration. The three differences in the temperature of the evaporative vacuum produced the total phenol content cooling. The overall phenol content obtained decreases with increasing solvent ratio addition. Although the evaporative vacuum cooling treatment at 45 °C yielded the highest total flavonoid content (1.2418±0.2365 mg QE/g) at a 1:2 solvent ratio, the total flavonoid content varied between the three evaporative vacuum cooling temperature variations. The yield of total phenolic and flavonoid compounds was not significantly affected by temperature gradient adjustments or the ratio of galangal extract to solvent (Sig. > 0.05) in any of the data samples pertaining to phenolic and flavonoid compounds. Keywords: Evaporative vacuum cooling, Flavonoids, Galangal, Phenol.

Published: October 2024

Abstract
Osteoblastoma and osteoid osteoma are rare benign bone tumours, sometimes considered variations of the same pathologic process. However, they differ in location, incidence, age group, and size. The gold standard treatment is surgical excision for osteoblastoma and radiofrequency ablation for both. Minimally invasive techniques, including radiofrequency ablation, microwave ablations, cryoablation, ultrasound ablation, and laser ablation, are increasingly used. This meta-analysis aimed to review current treatments, focusing on minimally invasive methods versus traditional surgical excision. A data comparison of 17 original articles from the PubMed database (2014-2024) was conducted, examining treatment methods, patient numbers, success rates, pre/post-operative pain scores, and complication rates. New ablation methods achieve similar clinical results to traditional surgery for treating osteoid osteoma and osteoblastoma while minimizing invasiveness. Most procedures have technical success rates near 100%. Both invasive and non-invasive methods significantly reduce preoperative pain. Classical surgery has higher minor complication rates compared to minimally invasive treatments. Among ablation techniques, magnetic resonance guided focused ultrasound surgery is the least invasive, avoiding radiation and antibiotic-related complications. However, in ablation methods caution is needed to prevent thermal damage to nearby joints and nerves. Protective methods, such as skin protection, hydrodissection, gas dissection, and intraoperative neurostimulation, are recommended. New ablation methods provide less invasive alternatives to surgery, with high clinical and technical success rates and lower complication rates. Among these, magnetic resonance guided focused ultrasound surgery is the least invasive and most promising, though more clinical data is needed due to its recent development.

Published: October 2024

Abstract
Trade and cultural exchanges introduced American fruit trees to China’s Lingnan region following the Age of Exploration. By analyzing historical records from the Ming Dynasty to the Republic of China, a comprehensive outline of the cultivation history of these fruit trees in Lingnan can be constructed. Both natural and social factors are responsible for the successful introduction of these species. Lingnan’s advantageous geographical location and favorable climate provided ideal conditions for their growth, while the region’s robust trade networks, large overseas Chinese population, and long-standing tradition of fruit tree cultivation facilitated their introduction and dissemination. The introduction of American fruit trees enhanced Lingnan’s agricultural diversity, optimizing land use and increasing agricultural productivity, paving the way for the region’s fruit industry to flourish.

Abstract
Diving decompression sickness is an occupational chronic disease that seriously threatens the life and safety of divers, which is hidden, lasts for a long time, and causes more serious harm. The clinical manifestations are complex, including joint pain, muscle pain, rash, fatigue, headache, coma, and so on. This paper explores the value formation mechanism of chronic disease health management based on big data based on information ecology chains and dissipative structures. A total of 1036 divers engaged in diving and fishing operations are being taken as experimental subjects in the chronic disease health management big data platform using a stratified whole-group sampling method. XGBoost algorithm was used to establish the risk assessment model of chronic decompression sickness for divers. And it was applied to the clinic for example, to analyze the effectiveness of the model for chronic health prevention in divers. The results show that the model has a predictive performance AUC value of 0.8102 in 5-fold cross-validation, which can be used for chronic health risk assessment of large-scale diving populations by medical personnel to guide early diagnosis, treatment, and prevention of chronic health in divers.
Adaptation of Marxian Economic Theory in Digital Currency System Based on Blockchain Technology
Authors: Xu Qi 
Published: October 2024

Abstract
This paper analyzes the current status of digital currency trading in terms of volume, price, and quantity in circulation and compares the statistical descriptions of Bitcoin, Dogecoin, and Ether to illustrate whether cryptocurrencies have the potential to be Marxist world currencies by observing the price volatility and the size of the trading volume. Introducing Bitcoin as a commodity, the relationship between risk volatility, capital control, capital flight, and the Bitcoin premium is mechanistically portrayed. The existence of bitcoin-channeled capital flight is argued based on typical facts and empirical evidence. The results show that as of November 25, 2023, Bitcoin’s single-day volume is about $64 trillion, the highest market share among more than 2,000 currencies in the world. Its single price is volatile, with a high of about $4,500 and a low of about $7. The price of Dogecoin and Ether can fluctuate between 56% and 489%. The Marxist definition of a world currency excludes digital currencies. BTC doesn’t fully align with ECNY, there’s a possibility of a Bitcoin premium, and there’s also a risk of capital flight. Therefore, an adaptive analysis of digital currencies based on blockchain technology based on Marxian monetary and economic theories can provide a clear understanding of the nature of money and monetary functions.
A multidimensional exploration of environmental art design for public space based on var modeling
Authors: Li Juanjuan 
Published: October 2024

Abstract
How to create a people-oriented and unique public art space has become an ongoing concern for urban designers and industry scholars. In this paper, based on the artistic design characteristics of the public space environment and its main functions, a questionnaire is designed to obtain the public’s satisfaction with public art space and perception of multidimensional elements in art design. The multidimensional analysis method is proposed based on the VAR base model. The cointegration test examines the stability of the model. Then, the impact of the dimensional elements of art design on public satisfaction of the public space environment is analyzed by the impulse response and variance decomposition methods. The cointegration test shows that there is a correlation between satisfaction, acceptance, and sense perception of public spaces and perception of art design, which supports the subsequent research. Regionality and diversity in art design were found to be Granger’s causes of public satisfaction and acceptance of public art space environments at the 1% confidence level (p<0.01). In addition, after a 2-period impulse response delay, the variance contribution of morphological and textual elements to public satisfaction, etc. It was kept at a significant level (2.055%-4.994%). This paper provides a theoretical basis and a methodological exploration for art design research in the field of public art space.

Abstract

Objective. Carboxypeptidase E (CPE) plays an important role in the biosynthesis of neurotransmitters and peptide hormones including insulin. It also promotes cell proliferation, survival, and invasion of tumor cells. The endoplasmic reticulum stress, hypoxia, and nutrient supply are significant factors of malignant tumor growth including glioblastoma. There are data indicating that the knockdown of the endoplasmic reticulum to nucleus signaling 1 (ERN1) suppressed glioblastoma cell proliferation and increased invasiveness of these cells. The present study aims to investigate the regulation of the CPE gene in U87MG glioblastoma cells by ERN1 knockdown, hypoxia, and glucose or glutamine deprivations with the intent to reveal the role of ERN1 signaling in the regulation of this gene expression and function in tumorigenesis.

Methods. Human glioblastoma cells U87MG (transfected by an empty vector; control) and ERN1 knockdown cells with inhibited ERN1 endoribonuclease and protein kinase (dnERN1) or only ERN1 endoribonuclease (dnrERN1) were used. Hypoxia was introduced by dimethyloxalylglycine; for glucose and glutamine deprivations, the cells were cultured in DMEM medium without glucose or glutamine for 16 h, respectively. The expression level of the CPE gene was studied by quantitative RT-PCR and normalized to ACTB.

Results. It was found that inhibition of endoribonuclease and protein kinase activities of ERN1 led to a strong up-regulation of CPE gene expression in glioblastoma cells. The expression of this gene also increased in glioblastoma cells after silencing ERN1. At the same time, the expression of this gene did not significantly change in cells with inhibited ERN1 endoribonuclease only. The expression of the CPE gene was resistant to hypoxia in control U87MG cells, but increased in cells with ERN1 knockdown. The expression of this gene was up-regulated under glutamine deprivation in control glioblastoma cells, but decreased upon ERN1 knockdown. However, glucose deprivation decreased the expression of CPE gene in both types of used cells, but ERN1 inhibition enhanced this effect.

Conclusion. The results of the present study demonstrate that inhibition of ERN1 strongly up-regulated the expression of pro-oncogenic CPE gene through protein kinase activity of ERN1 and that increased CPE gene expression possibly participates in ERN1 knockdown-mediated invasiveness of glioblastoma cells.
Decentralized control of nonlinear complex systems
Authors: Veselý Vojtech , Paulusová Jana , Körösi Ladislav 
Published: October 2024

Abstract
In the paper, a novel approach to decentralized controller design for nonlinear systems is introduced. The proposed method is based on the relationship between the stability of complex nonlinear systems and the stability of their subsystems. The design procedure of the decentralized controller consists of three steps. In the first step, the stability of the complex nonlinear system is calculated. In the second step, stability conditions at the subsystem level are obtained such that guarantee the stability of the complex nonlinear system. Finally, in the third step, a controller design method is used to ensure that the subsystem stability conditions obtained in the second step are met. As an example, to better understanding the proposed method two simple nonlinear models are used to demonstrate the effectiveness of the proposed method.

Published: October 2024

Abstract
Low inertia poses a significant challenge to the widespread integration of photovoltaic (PV) systems into the grid, particularly affecting frequency stability. This paper addresses this challenge by proposing an advanced hybrid inertia (AHI) approach, characterized by the integration of real and virtual inertia, combined with the application of intelligent control techniques, to enhance the primary frequency response of a PV system. Internal inertia is provided by a synchronous generator (SG) acting as a compensator, while virtual inertia is generated through a real-time deloading strategy in the PV plant. The AHI is implemented on an isolated grid, utilizing various intelligent control techniques to improve frequency stability. The intelligent techniques employed include genetic algorithms (GA) and fuzzy logic controllers (FLC), which do not require mathematical modeling. This allows them to overcome the nonlinear dynamics of the PV plant and the uncertainties associated with climatic changes. These techniques are applied to the nonlinear components on the generator side, including the governor loop, DC-DC converter loop, and power reserve injection management loop. A frequency fluctuation scenario, induced by generating power perturbations in the proposed system, demonstrates and validates the improvement in frequency stability achieved by the HI and intelligent techniques. All tests are conducted using MATLAB Simulink. Various simulation results show a significant improvement in frequency stability through the incorporation of HI and intelligent control techniques.
Models and methods for RZ-signals distinction in non-Gaussian noise for information-measurement systems
Authors: Palahin Volodymyr , Zorin Oleksandr 
Published: October 2024

Abstract
Polynomial Decision Rules (DR) for the problems of discrete RZ (Return-to-Zero) signal distinction in asymmetric-excess non-Gaussian noise are proposed. A new approach is proposed, which is based on the use of a modified moment quality criterion of statistical hypothesis testing and the application of higher-order statistics to describe the characteristics of non-Gaussian noise. Simulation of the DR with different parameters of the signal and noise was carried out. It is shown that taking into account the coefficients of skewness and kurtosis of the non-Gaussian noise the efficiency of signal distinction increases with non-linear processing DR compared to known results, which are optimal for the Gaussian noise model. The conducted studies demonstrate a reduction in false decisions in the processing of RZ signals when considering the coefficients of skewness and kurtosis of non-Gaussian noise. Such an increase in efficiency can exceed twofold, depending on the noise parameters. It is shown that the efficiency of the proposed approach is much higher for small SNR (Signal-to-Noise Ratio) values, for example, less than 1.

Authors: Esmer Sadullah , Aytar Oktay 
Published: October 2024

Abstract
In this study, Si, SiC, and GaN based semiconductor switching elements to be used in the design of new generation high gain DC-DC converters are compared. Each switching element is tested at different frequencies and different pulse period ratios. The efficiency and output voltage of the high gain boost converter are analyzed in detail according to the switching element used. The amplifiers have been investigated at 50 kHz and 5 MHz switching frequencies. The results show that the converter using GaN-based MOSFET is more efficient than converters using other MOSFETs and reaches the highest efficiency at 200 kHz switching frequency. The proposed converter achieves 91.68% efficiency and 2.66 voltage gain at 0.3 pulse period rate, 94% efficiency and 3.78 voltage gain at 0.5 pulse period rate and 93.94% efficiency, and 6.33 voltage gain at 0.7 pulse period rate. Thus, it is understood that when GaN based MOSFETs are used in high gain DC-DC converters, higher gain and higher efficiency are achieved.

Published: October 2024

Abstract
This contribution is an extended in-depth study of our previously initial research work about the compact Log-periodic microstrip DGS lowpass filters. The improved filters proposed use a log-periodic zig-zag structure defected on the ground plane under a compensated microstrip line for microwave filter applications. More importantly, a comprehensive index called figure-of-merit (FoM) is introduced in this paper to characterize the achieved performance of this kind of filters. Results show that high FoMs can be realized for this contribution. The developed filters B and C have dimensions 30.307 mm × 31.17 mm and 22.35 mm × 31.524 mm, while the achieved FoMs for the two demonstrators are approximately 3.5×104 and 3.1×104, respectively.
