New family of root-finding algorithms based on inverse rational interpolation
Authors: Dzunic Jovana
Published: February 2023

Inverse interpolation with rational functions is investigated for the use in iterative refinement of the root approximation. A new family of optimal methods of arbitrary large order of convergence for solving nonlinear equations is presented. Experiments are conducted to check the influence of polynomial degrees in numerator and denominator on convergence properties of the proposed methods. Wolfram Mathematica 12 software was used to carry the computation due to its capabilities of arbitrary large precision arithmetic.

Authors: Su Yi , Chen Yifeng , Sui Chunjie , Bi Tianjiao , Chen Wei , Zhang Bin
Published: February 2023

As a high energy density hydrogen-rich carrier, ammonia (NH3) is a highly promising carbon-free fuel. The large-scale industrial application of NH3 is limited by its low reactivity and high NOx emission. In this work, the flame and emission characteristics of ammonia/methane (NH3/CH4) non-premixed combustion were investigated under ultrasonic excitation. An experimental system was designed and built, including non-premixed combustion system, loading ultrasonic system, deflectionmography temperature measurement system and flue gas measurement system. Combustion and measurement experiments at different ultrasonic frequencies and NH3/CH4 blending ratios were carried out. Flame images and flue gas species concentrations under ultrasonic excitation were acquired. The 3-D temperature field was reconstructed. The influence of ultrasonic excitation at different frequencies on flame characteristics, flame temperature field and emission characteristics of the combustion process was analysed. The mechanism of NH3/CH4 combustion enhancement and emission reduction was revealed when the flame was ex-cited by ultrasonic waves. Results showed that part of the hydrocarbon fuels was replaced by NH3 to reduce CO2 emission. The height and color of the NH3/CH4 flame were changed and the high temperature area of the flame gradually expanded as ultrasonic acted on the flame. As ultrasonic frequency increased, the emission concentrations of unburned CH4, unburned NH3, and NO decreased significantly. The flame was ex-cited by ultrasonic waves, which reduced its local equivalent ratio, improved combustion efficiency and suppressed NOx generation.

Based on the available literature, the status and prospects for further development of the building integrated photovoltaics (BIPV) market were analyzed. The results of the analysis show that the high investment costs and the lack of information about installed BIPV systems and BIPV technology are a problem for the stakeholders. The BIPV technology is an interdisciplinary problem, so the cooperation of a large number of different experts is important. However, it is not yet at a satisfactory level. Another problem is the overlapping of responsibilities of HVAC installers, interior designers and fa?ade manufacturers. On the other hand, the incentives of the EU regulatory framework and beyond to use RES in both new buildings and renovation of old buildings, as well as the desire for energy independence, encourage the application of BIPV technology. An analysis of the electricity production potential of BIPV integrated into the walls and roof of the building was made for four geographical locations. A comparison of the production of electricity on the walls and on the roof of the building was carried out. The analysis shows that on the four walls of the building, where each wall has the same area as the roof of the building, approximately 2.5 times more electricity than on the roof can be generated. In the absence of available surface for installing a photovoltaic power plant on the roof, the walls represent a great potential for BIPV technology.
Bidirectional analysis model of green investment and carbon emission based on LSTM neural network
Authors: Hu Yiguo
Published: February 2023

Clarifying how the green investment alleviates carbon emissions paves the way for achieving carbon peak and carbon neutralization at a faster pace. In order to propose an effective evaluation model and analyze the interaction between green investment and total carbon emissions, we first and foremost collected data from 30 provinces in China from 2007 to 2019. Secondly, we introduced long short-term memory (LSTM) neural network model, with the amount of government investment in pollution control and environmental infrastructure construction as the model input variables. We also select the total amount of carbon emissions as the model output variables to obtain a neural network model with multiple inputs and a sin-gle output, which can effectively analyze the potential relationship between green investment data and the total amount of carbon emissions data. Then, the OLS model is introduced to test the relationship obtained by LSTM neural network model and analyze its robustness. As a result, the experiment indicates that the LSTM network conceived by us has reliable robustness and fitting performance, with green investment positively affecting total carbon emissions. Meanwhile, we give corresponding policy recommendations according to the model results.

High-throughput proteomics allows researchers to simultaneously explore the roles of thousands of biomarkers in the pathophysiology of diabetes. We conducted proteomic association studies of incident type 2 diabetes and physiologic responses to an intravenous glucose tolerance test (IVGTT) to identify novel protein contributors to glucose homeostasis and diabetes risk. We tested 4,776 SomaScan proteins measured in relation to 18-year incident diabetes risk in participants from the Cardiovascular Health Study (N = 2,631) and IVGTT-derived measures in participants from the HERITAGE Family Study (N = 752). We characterize 51 proteins that were associated with longitudinal diabetes risk, using their respective 39, 9, and 8 concurrent associations with insulin sensitivity index (SI), acute insulin response to glucose (AIRG), and glucose effectiveness (SG). Twelve of the 51 diabetes associations appear to be novel, including β-glucuronidase, which was associated with increased diabetes risk and lower SG, suggesting an alternative pathway to insulin for glucose disposal; and plexin-B2, which also was associated with increased diabetes risk, but with lower AIRG, and not with SI, indicating a mechanism related instead to pancreatic dysfunction. Other novel protein associations included alcohol dehydrogenase-1C, fructose-bisphosphate aldolase-B, sorbitol dehydrogenase with elevated type 2 diabetes risk, and a leucine-rich repeat containing protein-15 and myocilin with decreased risk.

Article Highlights

Plasma proteins are associated with the risk of incident diabetes in older adults independent of various demographic, lifestyle, and biochemical risk factors. These same proteins are associated with subtle differences in measures of glucose homeostasis earlier in life. Proteins that are associated with lower insulin sensitivity in individuals without diabetes tend to be associated with appropriate compensatory mechanisms, such as a stronger acute insulin response or higher glucose effectiveness. Proteins that are associated with future diabetes risk, but not with insulin insensitivity, tend to be associated with lower glucose effectiveness and/or impaired acute insulin response.

OBJECTIVE

Despite increasing evidence demonstrating structural and functional alterations within the central nervous system in diabetic peripheral neuropathy (DPN), the neuroanatomical correlates of painful and painless DPN have yet to be identified. Focusing on structural MRI, the aims of this study were to 1) define the brain morphological alterations in painful and painless DPN and 2) explore the relationships between brain morphology and clinical/neurophysiological assessments.

RESEARCH DESIGN AND METHODS

A total of 277 participants with type 1 and 2 diabetes (no DPN [n = 57], painless DPN [n = 77], painful DPN [n = 77]) and 66 healthy volunteers (HVs) were enrolled. All underwent detailed clinical/neurophysiological assessment and brain 3T MRI. Participants with painful DPN were subdivided into the irritable (IR) nociceptor and nonirritable (NIR) nociceptor phenotypes using the German Research Network on Neuropathic Pain protocol. Cortical reconstruction and volumetric segmentation were performed with FreeSurfer software and voxel-based morphometry implemented in FSL.

RESULTS

Both participants with painful and painless DPN showed a significant reduction in primary somatosensory and motor cortical thickness compared with HVs (P = 0.02; F[3,275] = 3.36) and participants with no DPN (P = 0.01; F[3,275] = 3.80). Somatomotor cortical thickness correlated with neurophysiological measures of DPN severity. There was also a reduction in ventrobasal thalamic nuclei volume in both painless and painful DPN. Participants with painful DPN with the NIR nociceptor phenotype had reduced primary somatosensory cortical, posterior cingulate cortical, and thalamic volume compared with the IR nociceptor phenotype.

CONCLUSIONS

In this largest neuroimaging study in DPN to date, we demonstrated significant structural alterations in key somatomotor/nociceptive brain regions specific to painless DPN and painful DPN, including the IR and NIR nociceptor phenotypes.

OBJECTIVE

Maintenance of glycemic control during and after exercise remains a major challenge for individuals with type 1 diabetes. Glycemic responses to exercise may differ by exercise type (aerobic, interval, or resistance), and the effect of activity type on glycemic control after exercise remains unclear.

RESEARCH DESIGN AND METHODS

The Type 1 Diabetes Exercise Initiative (T1DEXI) was a real-world study of at-home exercise. Adult participants were randomly assigned to complete six structured aerobic, interval, or resistance exercise sessions over 4 weeks. Participants self-reported study and nonstudy exercise, food intake, and insulin dosing (multiple daily injection [MDI] users) using a custom smart phone application and provided pump (pump users), heart rate, and continuous glucose monitoring data.

RESULTS

A total of 497 adults with type 1 diabetes (mean age ± SD 37 ± 14 years; mean HbA1c ± SD 6.6 ± 0.8% [49 ± 8.7 mmol/mol]) assigned to structured aerobic (n = 162), interval (n = 165), or resistance (n = 170) exercise were analyzed. The mean (± SD) change in glucose during assigned exercise was −18 ± 39, −14 ± 32, and −9 ± 36 mg/dL for aerobic, interval, and resistance, respectively (P < 0.001), with similar results for closed-loop, standard pump, and MDI users. Time in range 70–180 mg/dL (3.9–10.0 mmol/L) was higher during the 24 h after study exercise when compared with days without exercise (mean ± SD 76 ± 20% vs. 70 ± 23%; P < 0.001).

CONCLUSIONS

Adults with type 1 diabetes experienced the largest drop in glucose level with aerobic exercise, followed by interval and resistance exercise, regardless of insulin delivery modality. Even in adults with well-controlled type 1 diabetes, days with structured exercise sessions contributed to clinically meaningful improvement in glucose time in range but may have slightly increased time below range.

OBJECTIVE

To investigate the contribution of alterations in brain structure and function to cognitive function and their interactions in individuals with diabetes and patients with type 2 diabetes mellitus (T2DM).

RESEARCH DESIGN AND METHODS

This population-based study included 2,483 participants who underwent structural MRI (n = 569 with normal glucose metabolism [NGM], n = 1,353 with prediabetes, and n = 561 with T2DM) and cognitive testing. Of these, 2145 participants also underwent functional MRI (n = 496 NGM, n = 1,170 prediabetes, and n = 479 T2DM). Multivariate linear regression models were used to assess the association of brain volume and functional connectivity with cognition, as well as the association of brain volume and functional connectivity.

RESULTS

Compared with NGM participants, those with T2DM had lower brain volume in a wide range of brain regions and stronger functional connectivity between the bilateral thalamus and brain functional network (visual network and default mode network), and those with prediabetes had lower brain volume in specific local regions (subcortical gray matter volume and subcortical subregions [bilateral thalamus, bilateral nucleus accumbens, and right putamen]) and stronger functional connectivity between the right thalamus and visual network. Cognition was associated with greater right thalamus volume and lower functional connectivity between the right thalamus and visual network. Functional connectivity between the right thalamus and visual network was associated with lower right thalamus volume.

CONCLUSIONS

Cognition was associated with greater brain volume and lower functional connectivity in T2DM. Increased functional connectivity may indicate a compensatory mechanism for reduced brain volume that begins in the prediabetic phase.

Published: February 2023

Previous studies have suggested that persistent tobacco smoking impairs survival in cutaneous melanoma, but the effects of smoking and other prognostic factors have not been described in detail. This study examined the association of smoking (persistent, former, or never) with melanoma-specific (MSS) and overall survival (OS) in patients with cutaneous melanoma treated in Southwest Finland during 2005 to 2019. Clinical characteristics were obtained from electronic health records for 1,980 patients. Smoking status was available for 1,359 patients. Patients were restaged according to the 8th edition of the tumour-node-metastasis (TNM) classification. Smoking remained an independent prognostic factor for inferior melanoma-specific survival regardless of age, sex, stage, and comorbidities. The hazard ratio of death from melanoma was 1.81 (1.27−2.58, p = 0.001) in persistent and 1.75 (1.28−2.40, p = 0.001) in former smokers compared with never smokers. In 351 stage IV patients, smoking was associated with increased melanoma-specific and overall mortality: median MSS 10.4 (6.5−14.3), 14.6 (9.1−20.1), and 14.9 (11.4−18.4) months, p = 0.01 and median OS 10.4 (6.5−14.3), 13.9 (8.6−19.2), and 14.9 (11.7−18.1) months, p = 0.01 in persistent, former, and never smokers, respectively. In conclusion, since smoking represents an independent modifiable poor prognostic factor in patients with cutaneous melanoma, smoking habits should be proactively asked about by healthcare professionals, in order to support smoking cessation.

Background: Rates of return-to-work after stroke are low, yet work is known to positively impact people’s wellbeing and overall health outcomes.Objective: To understand return-to-work trajectories, barriers encountered, and resources that may be used to better support participants during early recovery and rehabilitation.Participants: The experiences of 31 participants (aged 25–76 years) who had or had not returned to work after stroke were explored.Methods: Interview data were analysed using reflexive thematic analysis methods within a broader realist research approach.Results: Participants identified an early need to explore a changed and changing occupational identity within a range of affirming environments, thereby ascertaining their return-to-work options early after stroke. The results articulate resources participants identified as most important for their occupational explorations. Theme 1 provides an overview of opportunities participants found helpful when exploring work options, while theme 2 explores fundamental principles for ensuring the provided opportunities were perceived as beneficial. Finally, theme 3 provides an overview of prioritized return-to-work service characteristics.Conclusion: The range and severity of impairmentsexperienced by people following stroke are broad, and therefore their return-to-work needs are diverse. However, all participants, irrespective of impairment, highlighted the need for early opportunities to explore their changed and changing occupational identity.
LAY ABSTRACTThe aim of this study was to understand how best to support people returning to work after a stroke. A total of 31 people who had or had not been able to return to paid work after stroke were interviewed. We listened to their experiences and considered what worked best for different people with a range of needs and aspirations. People talked about wanting opportunities soon after their stroke to explore changing thoughts about themselves and their ability to return to work. Conversations with participants and their families, often starting very early after stroke, were important. People also wanted opportunities to practise skills they typically used at work, such as social skills or planning and organizational tasks. Through these ongoing conversations and opportunities to practise, people talked about gradually regaining their confidence in the skills they had retained after their stroke, rather than focusing only on the difficulties they were experiencing.

An Analysis of The Old Man and the Sea in Christian, Universal and Buddhist Perspectives
Authors: Sa-ngiamwibool Amporn
Published: February 2023

Religion and literature share universal senses that touch human mind. The Old Man and the Sea by Ernest Hemingway, a Pulitzer-award and-Nobel-prize winner, which is full of Christianity symbols and allusions, is selected to verify this universality, with three specific purposes which aimed to analyze and draw out: 1) Christian symbols and allusions, 2) universal senses of life, and 3) Buddhist essence in the novella. The analysis revealed these findings. All symbols and allusions relate to Christ. The attempt to fight against inevitable destiny that is a universal and natural order of life touches the mind. The novella implicated two cores of Buddhist essence: the four noble truths and the eightfold path. It could be concluded that the line between literature and religion share universality which lies in human mind, regardless of religious beliefs.
Dignifying Children through Inclusive Children�s Literature

Published: February 2023

Children with disabilities are often considered less capable than those without disabilities. In Indonesian childrens literature, disability is under-represented and the need to start representing disability in Indonesian childrens literature is pressing. Inclusive books imposing on the development of empathy leads to actions in dignifying children of all types, with or without disabilities. Some inclusive childrens literature worldwide set good examples of dignifying children. This paper tries to elaborate the urgency of having accessible inclusive childrens literature in Indonesia by collecting and presenting examples of inclusive childrens literature around the world which represents disabilities as diversities in society.
Stand Up Comedy: Language Play and Its Functions (Systemic Functional Linguistic Approach)
Authors: Wijana I Dewa Putu
Published: February 2023

It is obviously misleading to regard that play-on-word activities are unimportant or trivial in human life. In many diverse societies, punning activities have very central roles in rituals as well as in cultural transformation processes. The importance of role played by punning activities attracts me to discuss the functions of language found in Stand Up Comedy, the most recent and popular comedy show broadcasted by Metro TV Station. This television program shows the skillfulness of comedians in telling jokes in front of its audience who are mostly teenagers or adolescents. Joking activities play central roles in human life because of their various functions, especially to criticize various social conditions that happen in the speakers community. However, to create unaggressive and constructive criticisms, the comedians build an intimate relation with their audience to create an effective deliverance. Consequently, they use certain moods of interaction using informal language styles which are full of ambiguities that can easily confuse audiences perceptions about many things. This is, of course, for the sake of eliciting audiences smiles and laughter. Keywords: stand-up comedy, language play, contextual framing

The Swings of Selendang: a Deconstruction Point of View of Tohari�s Ronggeng Dukuh Paruk (The Dancer)
Authors: Fajarini Suzana Maria L.A.
Published: February 2023

Employing different perspectives will result on different meanings of a scarf (selendang Javanese/Indonesian) in Ronggeng Dukuh Paruk (The Dancer). Known as an adornment and beautification for women in dancing costume, a scarf represents the shackle of the dancer, Srintil as the protagonist in the novel. In the different point of view, the same scarf can be a symbol of Srintils dominance against the patriarchal system. The novel itself shows subjugation towards women done by patriarchal system. Believed to be born as a ronggeng dancer, Srintil goes through oppressions since her early adolescent. However, employing Derridas deconstruction theory, this paper will argue that Srintil attempts very hard to achieve her liberation and to overturn the control. The swings of the scarf during the dancing denote the domination of the dancers fated life and her self-determination as a woman. Under a strong influence of Javanese female negotiation, Srintil endeavors to liberate herself although she is rendered to be unsuccessful yet, there are some efforts done by her. Through some discussion the readers are supposed to observe that Srintil who is treated unjustly by patriarchal society manipulatively resists and fights for her freedom.Keywords: deconstruction, patriarchal system, subjugation, resistence
Modulation: A Translation Method to Obtain Naturalness in Target Language Texts
Authors: Putranti Adventina
Published: February 2023

One of the requirements in order to produce equivalent translation is that the translation must sound natural for target language (TL) readers both lexically and grammatically. This naturalness can be obtained through the use of both lexical items and grammar familiar to the TL readers. However, naturalness in translation is not always easy to achieve. One of the causes is the difference in the way the source language (SL) and TL readers express a certain message in their languages. According to Vinay and Darbelnet (1995) this difference can be overcome by applying a translation method called modulation. Modulation is a method in which translators try to maintain naturalness by using various form the message done by changing the point of view. This procedure is usually chosen when translators find that literal translation would result in awkward or unnatural translation.Keywords: modulation, naturalness, equivalence
Elements of Nature as the Object of Escapism in Maya Angelou�s �Woman Work�
Authors: Yustisiana Rr. Arielia
Published: February 2023

The research aimed to discuss the elements of nature in the poem entitled Woman Work written by Maya Angelou. The speaker of the poem used nature as the object of escapism. The research used some theories to meet the topic of discussion. The basic theories of the research were symbol, imagery and figures of speech. They were two figures of speech as the poetic devices in the poem: personification and apostrophe. They were two supporting theories that dealt with the topic, i.e. nature and escapism. There were two approaches that were used: structural and formalistic approaches. Library research is the technique of collecting data. The finding of the research was that the speaker of the poem endowed the elements of nature (which are non-living objects) with human qualities in an attempt to feel less lonely. In the absence of human company, it was the sun, the rain, the snow, dewdrops, the wind, the sky, mountains, oceans, leaves, stones, star shine and moon glow that were her friends. Woman Work was a very domestic poem depicting the typical routine life of a woman who performed her daily chores effectively and then yearned for a fantastic break amidst the elements of nature to give her strength and comfort.Keywords: nature, escapism, symbol, imagery, personification

This research presents a simulation study on electromagnetic behaviour of magnetic flux density distribution in a magnetorheological elastomer (MRE) bushing. The design concept of MRE bushing is based on the design of the bushing used in the conventional car, only the natural rubber is being replaced by the MRE compound. Furthermore, the electromagnetic simulations wereconducted by using Finite Element Method Magnetics (FEMM) software where the main aim is for more magnetic flux density in the MRE, which indicates better performances for MRE bushing in this study. The best configuration of the MRE bushing for this study is using single coil, magnetic material for all parts except for coil bobbin, and the thickness of ring plate of 4 mm, which yield the highest magnetic flux density of 0.205 T. By using this configuration, the dynamic stiffness of this MRE bushing is ranging from 2259.13 N/mm to 2671.06 N/mm with the applied currents of 0.5 A to 2.5 A and frequencies from 1 Hz to 15 Hz. All in all, the optimized configurations improve the performance of MRE bushing remarkably.

The typical of beeswax, dammar, rosin, paraffin, and microcrystalline wax. batik wax compositions used in Malaysia consist of various blends This study aims to characterize soy wax/beeswax blends’ structural, thermal, strength, and mass loss properties as potential alternative batik wax compositions. The Fourier transform infrared spectroscopy (FTIR) results showed that the additions of beeswax (wt%) into soy wax resulted in possible chemical interaction for the esters (C=O stretching and C-H bending vibrations), hydrocarbons (CH2 scissor formation), and cholestral esters (C=O stretching vibrations). The thermal profile obtained via differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) respectively revealed an increase in peak melting temperature and reduced thermal stability of the blends with further increments of beeswax. In addition, beeswax enhances the compression strength by 150% but did not have any significant impact on the modulus of the blends. E valuation of the mass loss test suggested that beeswax in the range of 40 wt% to 60 wt% can be considered as alternative batik resist material due to its moderate leaching tendency. Future works shall be conducted to evaluate the performance of these wax compositions against other batik wax criteria and the feasibility of printing these waxes using an in-house designed batik printer.
El Programa de Desarrollo Pesquero FAO-Instituto de Biología Marina de Mar del Plata (1960-1974)

Published: February 2023

Entre 1966 y 1974, el Instituto de Biología Marina de Mar del Plata llevó adelante el Proyecto de Desarrollo Pesquero en colaboración con la Food and Agriculture Organization (FAO). Su objetivo era identificar y evaluar los recursos pesqueros argentinos para desarrollar pesquerías de manera sustentable y producir alimentos para los sectores más vulnerables de los países periféricos. Sin embargo, ese objetivo no se logró. En este trabajo se analiza, a través de documentos y entrevistas, las características principales de este proyecto y su implementación. Se concluye que a pesar de que el proyecto promocionó tanto investigaciones orientadas a la explotación como a la conservación, el motivo principal de su fracaso estaría en las condiciones institucionales locales en las que se implementó.

Penelitian ini merupakan penelitian deskriptif dengan tipe korelasi yang melibatkan siswa kelas VII SMP Negeri 3 Leihitu. Variabel penelitian, yakni variabel minat belajar siswa (variabel X) dan variabel pencapaian hasil belajar fisika  (variabel Y), sedangkan teknik analisa data adalah analisis deskriptif dan analisis inferensial dengan metode korelasi. Hasil penelitian ini membuktikan bahwa minat belajar siswa memberikan hubungan yang signifikansi terhadap pencapaian hasil belajar fisika. Hasil penelitian menggambarkan bahwa minat belajar siswa yang diajarkan dengan menggunakan metode problem solving dapat mempengaruhi konsentrasi siswa dalam pembelajaran guna mencapai hasil belajar fisika. Dalam menggunakan metode problem solving, siswa  lebih berpikir dan bertindak kreatif dalam memecahkan masalah, dimana guru lebih banyak melibatkan siswa sebagai subjek yang mencari dan memecahkan sendiri dan bukan sebagai objek yang hanya menerima informasi dari guru, sehingga siswa dapat secara aktif belajar dan mengapresiasikan ilmu yang mereka terima di sekolah guna mengembangkan pengetahuan dan ketrampilannya
