Authors: Su Meishi , Yuan Jinliang , Yang Lixia , Chen Xueye
Published: September 2024

This paper introduces the multi-objective optimization process of the micromixer with Cantor fractal baffle. The combination of fractal principle and multi-objective optimization is a main feature of this article. The three-dimensional Navier–Stokes equation is used to numerically analyze the fluid flow and mixing. The proxy modeling and Pareto genetic algorithm are used to optimize the shape of the Cantor fractal micromixer. We choose three parameters related to the geometry of the Cantor fractal baffle as design variables, and choose the mixing index, pressure drop and mixing sensitivity at the outlet of the micromixer as three objective functions. For the parameter study of the design space, the Latin hypercube sampling (LHS) method is used to select design points in the design space. We use response surface function (RSA) as a proxy modeling to approximate the objective function. A multi-objective genetic algorithm is used to find the Pareto optimal solution. K-means clustering is used to classify the optimal solution set, and then select representative design variables from it. The representative optimal design is analyzed by using numerical analysis method. The optimization results show that the Cantor fractal baffle is beneficial to promote faster mixing of the two fluids. At the same time, the suitable goal can be weighed in the Pareto optimal solution set. The mixing index and mixing sensitivity are increased by 13.55  and 3.91 %, respectively, compared with the reference design of the micromixer. And we have also proved that this multi-objective optimization method is applicable to any Reynolds numbers (Res).
Data integrity cyber-attack mitigation using linear quadratic regulator based load frequency control in hybrid power system
Authors: Kapil Vivek , Prasad Sheetla
Published: September 2024

Hybrid power systems are the contemporary solution to meet the stiff climate change targets and also hold future for implementing distributed generation and microgrids. These systems have renewable sources as their key elements which in turn have high level of intermittency due to weather conditions and other reasons. At the same time, these hybrid power systems are also vulnerable to cyber threats owing to the intense adoption of various IoT Technologies (Internet of Things). Load frequency control (LFC) is a formidable task for the system operators under such scenario and robust control strategies are required to achieve the load frequency within tolerable limits. In this work Linear quadratic controller (LQR) has been proposed to address the challenges of hybrid power systems. Two area interconnected power systems are considered in this work with each one having different configuration with respect to source of power generation. Solar, wind, geo-thermal, electric vehicle charging infrastructure and pumped storage power plant are integrated together with conventional thermal power plant for showcasing the LQR based controller under data integrity cyber-attack scenario. The frequency response of the hybrid power system is demonstrated through MATLAB simulations.
Premature ovarian insufficiency in pediatric cancer patients: a 10 year Rady Children’s Hospital experience
Authors: Robinson Miranda , Meller Leo , Patterson Mary
Published: September 2024

Objectives

To highlight the occurrence of premature ovarian insufficiency in pediatric cancer patients and determine which patient characteristics or treatment modalities are associated with ovarian failure and recovery.

Methods

Between August 2011–August 2021, 36 of 2,661 patients with cancer were identified to have subsequent ovarian failure. Data collected included cancer type, diagnosis age, types of chemotherapy, bone marrow transplant or radiation treatment, peak follicle-stimulating hormone (FSH), peak anti-Mullerian hormone (AMH), gonadotropin releasing hormone agonist (GnRHa) treatment, type of hormone replacement therapy, and if ovarian function recovery occurred.

Results

The most common cancer type identified was ALL. The mean age of diagnosis was 8.5±4.3 years and mean age of peak FSH value was 12.6±2.8 years. Most patients (97.2 %) were treated with alkylating agents and 72.2 % received radiation. Most patients (72.2 %) received hormone therapy, and 15.8 % of patients received GnRHa Lupron. Ten patients (27.8 %) had ovarian function recovery. Diagnosis age and treatment type were recovery predictors in multivariate regression modeling. Each year older in age was associated with a 30 % decrease in odds of recovery (OR: 0.7, CI: 0.5–0.95, p=0.035), and alkylating agent treatment without transplant was associated with a 3-fold increase in odds of recovery (OR: 3, CI: 2.7–564, p=0.007).

Conclusions

This retrospective review demonstrates that POI can occur in pediatric cancer survivors, emphasizing the importance of educating patients on potential long-term effects of cancer treatment and importance of routine surveillance. This study confirmed that recovery of ovarian function is possible, especially when diagnosed at a younger age, making continued monitoring essential.
Exploring arteriolar atherosclerosis: laminar blood flow across stenosis with fluid-structure interaction and gravitational effects
Authors: Narayan S Shankar , Animasaun Isaac Lare , Muhammad Taseer
Published: September 2024

In response to the unanswered relevant questions surrounding atherosclerosis, it becomes imperative to investigate arterioles using sophisticated mathematical modelling techniques to shed light on critical stress and strain patterns influenced by gravity. The primary objective of this study is to scrutinize flow characteristics and probe stress and strain distributions experienced by the intima layer of arterioles, encompassing coronary, renal, cerebral, mesenteric, and pulmonary arteries, under gravitational forces. This investigation employs a fluid-structure interaction methodology utilizing arbitrary Eulerian–Lagrangian formulation. The study delves into blood flow characteristics within coronary, renal, cerebral, mesenteric, and pulmonary arterioles using the fluid-structure interaction technique, employing an arbitrary Eulerian–Lagrangian formulation. It thoroughly examines various biomechanical parameters such as the Cauchy–Green stress tensor, Principal strain, Piola–Kirchoff stress tensor, deformation tensor, and volume strain along the intima layer under the gravitational influence, elucidating vulnerable regions prone to endothelial dysfunction. Higher values of δV are found at the left shoulder and in the intima’s post stenosis area due to the pressure gradient along the flow channel, whereas other intima regions show a null volume strain. A thorough understanding of stress distribution is essential to create focused therapies to lessen vascular health problems. The stress in the post-stenosis region seems to affect the endothelial layer to a significant extent.

Published: September 2024

Archaeological cultures present allegories of ethnic identities across the centuries or millennia but such conceptualisations are necessarily incomplete and lack the resolution to explore transitions between cultures. Here, exploration of the archaeological contexts, production methods, stylistic variation and radiocarbon dating of 20 preserved textile fragments facilitates an examination of cultural change at Huaca del Sol (Huacas de Moche, northern Peru). While occupants of the site experienced many outside cultural influences, including those from the highland Wari Empire, continuity in textile traditions suggests that some sense of Moche identity was maintained through the tenth century and after the perceived end of the Moche culture.

Septin6 as a new approach for AD treatment
Authors: Liu Shuo , Pei Huibing , Zeng Duan , Deng Yuanyuan , Xie Weijie
Published: September 2024

The number of Alzheimer’s disease (AD) patients is increasing and new therapeutic approaches need to be proposed urgently. In recent years, some researchers have focused on the relationship between calcium homeostasis and AD; however, selective regulation of abnormal calcium signaling pathways and related targets of action remain unclear, presenting a challenge. Gerard Griffioen’s team in Belgium has proposed a self-reinforcing amplification between cytoplasmic calcium concentration [Ca2+]cyto and AD pathology in previous studies, discovering a new kind of small-molecule scaffold protein. The protein, ReS19-T, can stabilize the structure of septin filaments and significantly improve the core pathology of AD by inhibiting the pathological activation of store-operated calcium entry (SOCE) and restoring calcium homeostasis, thereby suggesting a new avenue for therapeutic intervention. However, there is still a way to go before clinical application. There are some questions. SEP2/6/7 hexamer plays a role in maintaining immune function, so could ReS19-T affect this function and impact immune responses? Moreover, both Stim1 and Orai (affected by TRPC) contribute to SOCE. The TRPC-specific inhibitor SKF-96365 is highly selective, and its relationship with AD remains to be investigated. Future studies might use SKF-96365 to validate the therapeutic effect of Res19-T. In conclusion, Septin6 as a new approach to AD treatment expects more relevant research to emerge.
Examining Brain Activity Responses during Rat Ultrasonic Vocalization Playback: Insights from a Novel fMRI Translational Paradigm

Published: September 2024

Despite decades of preclinical investigation, there remains limited understanding of the etiology and biological underpinnings of anxiety disorders. Sensitivity to potential threat is characteristic of anxiety-like behavior in humans and rodents, but traditional rodent behavioral tasks aimed to assess threat responsiveness lack translational value, especially with regard to emotionally valenced stimuli. Therefore, development of novel preclinical approaches to serve as analogues to patient assessments is needed. In humans, the fearful face task is widely used to test responsiveness to socially communicated threat signals. In rats, ultrasonic vocalizations (USVs) are analogous social cues associated with positive or negative affective states that can elicit behavioral changes in the receiver. It is therefore likely that when rats hear aversive alarm call USVs (22 kHz), they evoke translatable changes in brain activity comparable with the fearful face task. We used functional magnetic resonance imaging in male and female rats to assess changes in BOLD activity induced by exposure to aversive 22 kHz alarm calls emitted in response to threatening stimuli, prosocial (55 kHz) USVs emitted in response to appetitive stimuli, or a computer-generated 22 kHz tone. Results show patterns of regional activation that are specific to each USV stimulus. Notably, limbic regions clinically relevant to psychiatric disorders (e.g., amygdala, bed nucleus of the stria terminalis) are preferentially activated by either aversive 22 kHz or appetitive 55 kHz USVs. These results support the use of USV playback as a promising translational tool to investigate affective processing under conditions of distal threat in preclinical rat models.

Authors: Fernando E S , Quimado M O , Trinidad L C , Doronila A I
Published: September 2024

Uptake of nickel and three other heavy metals (copper, cobalt, and chromium) was examined in 33 species of the common and rare native vascular plants growing in an ultramafic area currently subjected to mining in Zambales Province, Luzon, Philippines. Leaf tissue samples were initially screened in the field using filter paper impregnated with dimethylglyoxime (1% solution in 70% ethyl alcohol) and later analyzed by atomic absorption spectroscopy. One species was found to be a hypernickelophore (>10,000 Âµg/g), eight species were nickel hyperaccumulators (>1,000 Âµg/g), nineteen species were hemi-accumulators (>100-1,000 Âµg/g), and five species were non-accumulators (<100 Âµg/g). This paper significantly adds to the list of hyperaccumulator species first reported for the Philippines in 1992. The findings will be discussed in context of using indigenous species for post mining ecological restoration and nickel phytoextraction in small-scale mining in the Philippines

Published: September 2024

The purpose of this study was to evaluate the socio-economic impact of land degradation and the role of watershed management in the development of agroforestry to support food safety and security. This study used descriptive analytical method that was based on the observations, interviews, and literature survey. Thirty respondents were randomly selected for this study. The results showed that the socio-economic impact of land degradation was the decline production of cassava for the last four years. Watershed management played an important role in the development of agroforestry to support food security. Agroforestry-based soil conservation did not run optimally due to a number of obstacles in its development. The development constraints were large area of critical lands and lack of technology transfer on watershed management. Policies needed in the development of agroforestry-based soil conservation to support of food safety and security are improvement of formal and nonâ€“formal educations, adoption of watershed management technology, and empowerment of farmers for agroforestry development.

Authors: Urip Sri Rejeki , Pudjitriherwanti Anastasia , Umam Khotibul
Published: September 2024

Learners of French as a foreign language are expected to be able to use French as French native speakers  (bien français). In communication, not all meaning comes from the words spoken. Speeches that contain things like this are called conversational implicatures. Understanding foreign language conversational implicatures is difficult. Learners are required for this ability to be able to communicate like native speakers. The present study intends to know to what extent learners understand conversational implicatures. This study follows Bouton and Pratama's research examining the understanding of conversational implicatures in English as a second language. Respondents of this research were 55 students studying French as a foreign language. In collecting the data,  three types of tests were used, namely:  (1) a Test of Conversational Implicatures, (2) a Test of Vocabulary Mastery, (3) and Test of  Structure Mastery. There are 30 questions about 10 types of conversational implicatures, 30 vocabulary questions, and 30 structure questions.  The results of the study revealed that there were 8 questions answered incorrectly by more than 50% of respondents. It also shows that the most difficult types of Conversational Implicature are (a) Indirect Criticism,  followed by (b) Quantitative, (c) Qualitative, (d) Manner, and (e) MRR. By using Multiple Linear Regression Analysis, statistically it is revealed that vocabulary and structure mastery contributes to Conversational Implicatures understanding.

Southeast Asian Peace Revisited: A Call for More Comprehensive Explanation
Authors: Purba Elbinsar
Published: September 2024

Many authors have tried to explain why Southeast Asia has been able to successfully maintain regional peace and stability. However, far from being able to provide convincing and commonly accepted answer, the current theories suffer from competing explanations and leave the puzzle unresolved. This paper explains the cause of this stalemate and finds that there are characteristics specific to Southeast Asia that collectively determine the nature of its transformation, namely diversity, colonial experience, culture of indeterminacy, and underdeveloped and non-complementary economy. As result of these characteristics, there are diverse factors that shape its peace evolution, there is no dominant driver of peace, and the region evolves incrementally. The paper argues that, in turn these lead to a serious methodological challenge for research on Southeast Asian peace. The paper concludes by offering some suggestions to overcome the challenge.

This study aims to evaluate the effectiveness of using Canva as a digital drawing tool in improving drawing skills and engagement of elementary school students. Through quantitative design and descriptive analysis of data collected from 48 teachers in various public elementary schools in Central Java, the study found that the use of Canva had a significant positive impact on students' understanding of design concepts, creativity, and engagement. A total of 45.8% of respondents strongly agreed and 50% agreed that Canva helps students understand basic design concepts better. In addition, 56.3% of respondents agreed and 37.5% strongly agreed that students' creativity improved after using Canva, indicating that the platform provides ample space for students to experiment with different drawing techniques. In terms of engagement, 47.9% of respondents strongly agreed and 39.6% agreed that using Canva increased student engagement in art projects compared to traditional methods. In addition, 60.4% of respondents agreed and 35.4% strongly agreed that Canva allows for more effective collaboration between students on drawing projects. However, while the benefits are significant, most respondents feel that additional training is needed to optimize the use of Canva in art teaching. These findings show that integrating Canva into the drawing curriculum not only improves students' artistic skills, but also prepares them for success in the digital world of the future.

Dirbtinis kvailumas ir užkalbėjimai („jailbreaks“) kaip algoritminio kūrybiškumo forma
Authors: Keturakis Saulius
Published: September 2024

The article discusses the practices of creativity, where the aesthetics of conscious error is transferred to the realm of algorithms. Taking the so-called perspective of artificial stupidity as a point of reference, the article analyzes the conditions of creativity in an algorithmic culture where unpredictability has become unlikely. As one of the practices of artificial stupidity, the article discusses so-called jailbreaks, the purpose of which is to deliberately confuse large language models, forcing systems to behave outside the intended purpose defined by the manufacturer. The article puts forward the idea that jailbreaks are a new type of dual-purpose narratives, which, on the one hand, act as a technical tool that “breaks” the limitations of algorithmic media, and on the other hand, they are significant structures, facing the user and performing a certain function of self-reflection. The article formulates the narratological structure of jailbreaks and highlights its similarity to the narrative structure of conspiracy theories.

Subject and Purpose. The subject of the research is the statistical characteristics of the signal, noise, and interference and their distribution functions. The emphasis is on exploring the properties of these elements and assessing their impact on algorithms designed to detect and identify the manifestations of human breathing and heartbeat during rescue operations. The work seeks comprehensive descriptions of broadband structural noise to develop optimum digital signal processing algorithms and ensure quicker and more reliable detection and identification of information signals during rescue missions. Method and Methodology. The analysis is grounded on the mathematical modeling method. The distribution function of correlation function peaks for a pseudo-noise signal is synthesized considering the first moments. The estimates derived from this distribution are used to assess the influence of broadband structural noise on the performance of algorithms for detecting and identifying radar signals. Results. In the most important band, where signal spectral components bear information on human breathing and heartbeat, estimates of the first four moments of a random process have been made to contribute to an appropriate model of fluctuating broadband structural noise. Analytical expressions of the function of structural interference distribution have been derived. A specific case focused on the interference represented by a phase-shift keyed signal with randomly alternating ones and zeros has been examined. Estimates of probabilities of false alarms and target misses have been calculated across various signal-to-noise ratios. Furthermore, a procedure to determine an optimal signal-detection threshold has been proposed. Conclusions. Analytical expressions of the distribution density of broadband structural interference have been derived. Quantitative estimates have been calculated to assess the impact this interference exerts on algorithms designed for detecting and recognizing radar information signals for rescuers. An adaptive procedure adjusting a target detection threshold as interference varies during the radar operation has been proposed.

Subject and Purpose. The improvement of the atmosphere brightness temperature measuring method at frequencies of about 100 GHz is considered. The possibilities of the atmospheric carbon monoxide (CO) remote sensing instrument, developed at Institute of Radio Astronomy of the National Academy of Sciences of Ukraine were analyzed. They show that the functional of this instrument can be significantly expanded. It can provide more operational information about the troposphere, useful for aeronomy and radio astronomy. The purpose of this work is to improve the atmosphere brightness temperature measuring method in relation to the existing instrument. We determine the possibility of the spectroradiometer broadband channel to measure the sky brightness temperature. Methods and Methodology. A detailed analysis of the existing installation for monitoring atmospheric CO was carried out and the measurement method was improved. It is shown that the broadband channel of this instrument, created as a service, can be used to measure atmosphere brightness temperature. Such measurement will allow creating a database of the zenith brightness temperature of the sky at frequencies of about 100 GHz. Results. It is possible to create the base data of the brightness temperature of the sky at frequencies about 100 GHz. In order to do this, it is necessary to make only some modifications of the instrument. The main thing is to make changes to the data capture file of the broadband channel and create a program to convert the data obtained from the instrument into brightness temperature values according to the specified formulas. All necessary formulas for presenting observational results in the form of brightness temperatures are given. Conclusions. It has been proven that there is a possibility to create the base date of the troposphere brightness temperature over Kharkiv (Ukraine) at the frequencies of the short-wave part of the mm range. The high stability of the radiometric part of the installation allows determining the brightness temperature of the sky with an accuracy that is sufficient for aeronomical, radioastronomical and radiophysical studies. On the basis of analytical calculations and experimental data, the necessary modifications for creating such a base data are defined.

Subject and Purpose. The methods for precipitation remote sensing continue to be developed. One of the trends has been assessing amounts of precipitations to determine whether to issue alerts for large-scale floods and landslides or to make decisions regarding the agricultural land irrigation. The present work focuses on the inverse problem of dual-frequency sensing and its solution through Tikhonov regularization. The goal is to improve the algorithm for solving the inverse problem and retrieve a non-uniform rainfall intensity profile. The retrieval results are enhanced by taking into account the impacts of the signal attenuation and errors in the received power measurements. Methods and Methodology. The retrieval of a non-uniform spatial profile of rain intensity is carried out by the numerical simulation using the integral scattering equation solution via Tikhonov regularization and employing dual-frequency sensing data. Results. The numerical simulations of a non-uniform spatial profile of the rain intensity in the range 0…30 mm/h have been performed at the operating wavelengths 8.2 mm and 3.2 cm and for various errors of the received power measurement and complete attenuation of the signals. It has been observed that the signal attenuation at the shorter (8.2 mm) operating wavelength has a significant effect on the retrieved intensity of rains heavier than 5 mm/h and more distant than 1 km. For the longer (3.2 cm) operating wavelength, the signal attenuation can be neglected when the maximum intensity in the profile is under 30 mm/h and the distance is less than 20 km. The retrieval error of a non-uniform rain intensity profile is shown to be no worse than 40% for the intensities in the profile above 3 mm/h and measurement errors of ±20%. Conclusions. The analysis of the results has shown that the proposed dual-frequency approach to solving the integral scattering equation makes it possible to retrieve a non-uniform rain intensity profile with a maximum error no worse than 40% for rain intensities above 3 mm/h and with the proviso that the error of the received power measurement and complete attenuation of signals at the shorter (8.2 mm) operating wavelength is no worth than ±20%.

Published: September 2024

BACKGROUND AND OBJECTIVE

The financial burden of bronchiolitis-related hospitalizations in the United States surpasses $700 million annually. Procalcitonin (PCT) has garnered recent interest in pediatrics and has demonstrated the potential to decrease antibiotic usage in other illnesses. This study assessed PCT utilization trends in bronchiolitis, hypothesizing an annual increase in PCT testing.

METHODS

We conducted a multicenter, retrospective cross-sectional study utilizing the Pediatric Health Information Systems database. Infants aged 2 to 23 months presenting with bronchiolitis from January 1, 2016, to December 31, 2022, were included. Encounters with and without PCT testing were compared using χ2 testing and Wilcoxon rank-sum testing as appropriate. Temporal trends in PCT testing and correlations with hospital-level proportions of PCT use, antibiotic administration, and admission proportion were assessed using Spearman’s ρ.

RESULTS

There were 366 643 bronchiolitis encounters among 307 949 distinct patients across 38 hospitals during the study period. Of those, 1.5% (5517 of 366 643) had PCT testing performed. PCT usage increased more than 14-fold between 2016 and 2022 (0.2% in 2016 vs 2.8% in 2022, ρ > 0.99, P < .001). PCT use ranged from 0.01% to 8.29% across hospitals. The hospital-level proportion of PCT testing was not associated with admissions (ρ = 0.13, P = .42) or antibiotic use (ρ = 0.31, P = .06).

CONCLUSIONS

PCT testing in patients with bronchiolitis increased 14-fold between 2016 and 2022 and was not associated with decreased antimicrobial prescriptions. Further studies are needed to determine the diagnostic yield of PCT in bronchiolitis.

This paper delves into the significance of imaging in the diagnosis, aetiology and therapeutic guidance of heart failure, aiming to facilitate early referral and improve patient outcomes. Imaging plays a crucial role not only in assessing left ventricular ejection fraction, but also in characterising the underlying cardiac abnormalities and reaching a specific diagnosis. By providing valuable data on cardiac structure, function and haemodynamics, imaging helps diagnose the condition, evaluate haemodynamic status and, consequently, identify the underlying pathophysiological phenotype, as well as stratifying the risk for outcomes. In this article, we provide a comprehensive exploration of these aspects.

The phytodiversity of the floodplain of the Inhulets River in the Shyrokivsky district was studied and the bioecological characteristics of flora species were compiled based on the results of systematic, biological and ecological analyzes. It was found that the flora of the floodplain landscape is represented by 329 species belonging to 69 families. The spectrum of the studied flora is dominated by perennials among biomorphs, heliomorphs – heliophytes, trophomorphs – mesotrophs, hygromorphs – mesophytes, and cenomorphs – ruderals and pratants. In the studied flora, 20 species from the Red List of Dnipro region were recorded, three of which are included in the Red Book of Ukraine: Crocus reticulatus Stev. ex Adam., Ornithogalum bouscheanum (Kunth) Aschers and Tulipa quercetorum Klokov et Zoz. Rare species included in the Red Data Book of Dnipro region were recorded in the woody and shrubby vegetation of the studied area: Viburnum lantana L., Berberis vulgaris L., Rosa maeotica Dubovik. All of this emphasizes the significant conservation value of the studied floodplain. The adventitious flora is represented by 95 species (29.6% of the total flora of the floodplain), among which five species are invasive. The macrophytic vegetation of the Inhulets floodplain is distributed in the coastal shallow waters, which are on average up to 5 meters wide and are represented by intermittent bands of air-water and submerged vegetation. Higher aquatic vegetation is characterized by intermittent-zonal and border types of overgrowth. The results of the study show a fairly high phytodiversity of the floodplain of the Ingulets River – 22.94% of the total number of flora species of the Right Bank Steppe Dnipro region, and is also important for the creation of a cadastre of plant species of Ukraine and for river restoration and management.
