Published: March 2024

Dark matter is the cosmological link that stayed universe to multiuniverse. All universal parameters directly or indirectly show that the dark matter is the universe hidden energy or soul. We have no confusion about the existence of Dark matter. As it is the universe linker we can make a communication through it. May be higher intelligence out of universe( Alien) are working on it as every time we are receiving unidentified signal from outer space. Previous paper had shown that how the dark matter is established and expanded on the universe. This paper is showing about deep space frequencies, energy distribution with quantum fluctuation and dark matter communication. And at last is discussed for making a quantum mechanical signal for long distance like galaxy to galaxy communication. By dark matter communication we can make stronger of our deep space communication that can lead of our future space communication.

Authors: Gobato Ricardo , Regina Risso Gobato Marcia , Heidari Alireza
Published: March 2024

The electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency is a crystal oscillator. Particularly one using a quartz crystal works by distorting the crystal with an electric field, when voltage is applied to an electrode near or on the crystal. Other crystals such as rhodochrosite also have piezoelectric properties. The rhodochrosite as crystal oscillator for being an alternative to those of quartz. The rhodochrosite (MnC03) shows complete solid solution with siderite (FeC03), and it may contain substantial amounts of Zn, Mg, Co, and Ca. A molecular dynamic via molecular mechanics using the UFF (Universal Forces Field) provided the vibrational frequencies of the fundamental structure of the crystal molecule. The frequencies and vibrational temperatures of the unit cell of rhodochrosite obtained by UFF were calculated in the range from 0.6059 to 1,731.38 cm-1 and 0.87 to 2,491.06 K, respectively.Â Â

Authors: Aini Rosita Nurul , Retnowati Endah
Published: March 2024

Cognitive load theory menjelaskan pentingnya analisis kemampuan awal siswa dalam desain pembelajaran karena perbedaan kemampuan awal mengindikasikan perbedaan tingkat cognitive load yang dialami selama kegiatan pemecahan masalah. Adanya diferensiasi metode pembelajaran diduga lebih efektif sebagai pendekatan pembelajaran berdasarkan divergenitas tingkat kemampuan awal siswa. Penelitian ini bertujuan untuk menguji apakah terdapat perbedaan efektivitas pembelajaran statistika  dengan metode diferensiasi dan pembelajaran non-diferensiasi ditinjau dari kemampuan pemecahan masalah dan cognitive load siswa. Metode diferensiasi yang dikembangkan adalah dengan memberikan metode pembelajaran sesuai kategori tingkat kemampuan awal, yaitu jika rendah (metode worked example), sedang (metode faded example), dan tinggi (metode problem solving block). Penelitian quasi experiment dengan desain penelitian posttest only grup design ini melibatkan 60 siswa (novice) kelas VIII SMP dalam pembelajaran statistika berorientasi kemampuan pemecahan masalah.  Menggunakan uji ANCOVA dengan nilai pretest sebagai variabel kovariat diperoleh bahwa pembelajaran diferensiasi sama efektifnya dengan pembelajaran non-diferensiasi ditinjau dari pencapaian kemampuan pemecahan masalah. Namun, pembelajaran diferensiasi dapat menurunkan cognitive load siswa selama kegiatan pembelajaran.

Objetivo: Avaliar a prevalência das cirurgias ortognáticas mais indicadas e realizadas em todas as regiões geográficas do Brasil, considerando tipo de intervenção cirúrgica, base óssea tratada, faixa etária, sexo e grupo racial. Métodos: Foram entrevistados, por meio de questionários aplicados individual e presencialmente, 300 profissionais divididos igualmente em dois grupos: ortodontistas e cirurgiões buco-maxilo-faciais. Resultados: A média de idade dos profissionais foi equilibrada em ambos os grupos: 40,27±11,09 anos e 36,80±7,77 anos, respectivamente. A maior prevalência quanto à indicação e realização de cirurgia em todas as regiões do Brasil foi para o sexo feminino (75%), pacientes leucodermas (75%), com faixa etária entre 20 e 30 anos (71%). A base óssea com mais indicação foi “ambas” (maxila e mandíbula), com 53,76%. O mento isolado recebeu as menores indicações (2,51%). Em relação à maxila e mandíbula isoladas, observou-se diferença entre as regiões geográficas: nas regiões Norte, Nordeste e Sul, a mandíbula foi a segunda indicação mais prevalente; já no Centro-Oeste e no Sudeste, foi a maxila. Em todo o Brasil, 7% dos profissionais relataram não realizar tratamento ortodôntico-cirúrgico, estando a maioria deles concentrada na região Norte (20%). Conclusões: O avanço maxilar foi a mais prevalente das intervenções cirúrgicas, seguido pelo recuo mandibular, com uma diferença muito pequena (23,67% e 23,33%, respectivamente). A maioria dos pacientes portadores de desarmonias dentofaciais dos profissionais avaliados em todo o Brasil foi de mulheres, jovens, leucodermas, que apresentavam alterações esqueléticas em ambos os maxilares, com indicação e realização de cirurgias combinadas, sobretudo para avanço maxilar e recuo mandibular.

Published: March 2024

Eucalyptus are trees native to Australia and have been cultivated in various regions of the world. In its worldwide expansion, several native and exotic insects began to use these plants for their survival. Leptocybe invasa Fisher & La-Salle, 2004 (Hymenoptera: Eulophidae) is a gall wasp that lay eggs into leaves, young branches, and petioles causing galls; however, there are resistant and susceptible eucalyptus genotypes to gall formation. This study aimed to compare the chemical composition of eucalyptus genotypes and relate it to resistance and susceptibility to gall formation. Leaf oils were extracted by steam distillation and oil compositions were analyzed. The essential oils of eucalyptus genotypes resistant to gall formation had 12 constituents, which do not occur in susceptible genotypes, probably one of the factors that contributes to the resistance of these plants to gall formation. Thus, we suggest an early evaluation of resistant or susceptible eucalyptus genotypes, based on the chemical composition of the essential oils of these plants, avoiding economic losses of planting susceptible genotypes.

Published: March 2024

The safety and durability of concrete structures are prone to damage and result in significant harm to human society. Hence, monitoring and estimating the states of concrete structures is of great significance to protecting human safety. Graphene nanoplatelets (GNPs) and carbon nanotubes (CNTs) are promising candidates to endow cementitious composites with piezoresistivity for the health monitoring of concrete structures. Therefore, the aim of this article is to explore the effect of the hybrid GNPs and CNTs on behavior of cementitious composites with cooperation effects. The cementitious composites containing the hybrid GNPs and CNTs with simplified manufacturing methods are developed first. And then, the mechanical behaviors, electrical conductivities, and piezoresistive performances of the composites are investigated systematically. Finally, the modification mechanisms are also discussed. The results proved that the electrical resistivity of the composites with the hybrid GNPs and CNT concentration of 5.0 wt% is reduced by three orders of magnitudes, and the FCR and sensitivities are reached at 36.0% and 1.1% MPa−1/177.9, respectively. Its compressive strength/elastic modulus is achieved at 73.3 MPa/16.9 GPa. Therefore, the hybrid GNPs and CNTs modified cementitious composite present great potential application in monitoring and evaluating service states of civil infrastructures.

Background

Ageing, immobilization, sepsis or cachexia reduce muscle mass and function. The age-related loss, i.e. sarcopenia, contributes to frailty and results in a loss of mobility and autonomy in aging and disease. Affected individuals are often socially isolated, have a greater risk of metabolic disorders and psychosomatic problems. As a result, quality of life and life expectancy are affected. Immobilization and lack of adequate stimuli to the skeletal muscle seem to play a central part in these problems. To overcome them, resistance training (i.e., weightlifting) is an effective intervention.

Statement of the problem

Despite the efficacy of resistance training for increasing muscle mass and function, this treatment is underused in clinical practice. We argue that this is due to a lack of a generally applicable methodology.

Methods and framework

To address this and related problems, we have formed the Network of Expertise for Immobilization-induced Muscle Disorders (KNIMS) to develop a potential algorithm for treating sarcopenia and other immobilization-related muscle disorders. An important aspect of the proposed method is that it is defined as a formal algorithm that consists of two stages. Stage A aims to recover bed-ridden patients’ ability to stand by applying vibration-tilt table technology. Stage B aims at rehabilitating compromised gait, using a combination of squats, lunges and single leg raises. It is anticipated that this algorithm-based approach will enhance the ability for standardization and documentation, whilst reducing resource efforts at the same time, which will be equally useful to clinical practice and to clinical research.

Published: March 2024

Cornell, DJ, Gnacinski, SL, and Ebersole, KT. Changes in dynamic balance ability among firefighter recruits: A longitudinal cohort study. J Strength Cond Res 38(4): 734–741, 2024—It has been suggested that enhanced balance ability may mitigate the high musculoskeletal injury (MSKI) rate among firefighters, but the longitudinal changes in dynamic balance ability within this tactical athlete population have yet to be characterized. The purpose of this study was to examine the changes in dynamic balance ability of a cohort population of firefighter recruits completing a training academy and their probationary period as active-duty firefighters. Twenty-seven male firefighter recruits completed the modified Star Excursion Balance Test (mSEBT) at the beginning (W1) and at the end of their training academy (W14) and after completing their probationary period as active-duty firefighters (W38). After controlling for age and changes in body fat (BF) over time, significant changes in mSEBTANT ( p < 0.001), mSEBTPL ( p = 0.015), mSEBTPM ( p < 0.001), and mSEBTCOMP ( p = 0.003) were observed across time. Although mSEBTPL performance significantly increased ( p = 0.033) in from W1 to W14, significant decreases in all mSEBT reach directions were observed from W14 to W38 ( p < 0.05), with mSEBTANT ( p < 0.001) and mSEBTCOMP ( p = 0.002) also significantly decreasing from W1 to W38. However, the frequency of right vs. left asymmetries (>4 cm) did not significantly change over time in any mSEBT reach direction ( p > 0.05). Irrespective of age or changes in BF, minimal changes in the dynamic balance ability of firefighter recruits were observed during their training academy, but significant decreases in balance ability were noted by the end of their probationary period.

Weldon, A, Cloak, R, Kirk, C, Ruddock, A, Langan-Evans, C, Detanico, D, Loturco, I, and Kons, R. Strength and conditioning (S&C) practices of judo athletes and S&C coaches: A survey-based investigation. J Strength Cond Res 38(4): e160–e173, 2024—The benefits of strength and conditioning (S&C) for improving judo performance and reducing injuries have been widely studied. However, the S&C practices used and perspectives held by those delivering S&C have yet to be elucidated. Therefore, this study investigated the S&C practices and perspectives of judokas and S&C coaches working within judo. Forty-two judokas and 9 S&C coaches completed an online survey comprising 6 sections: (a) written informed consent; (b) background information; (c) education, qualifications, and prescription; (d) views on S&C; (e) exercise selection; and (f) issues and improvements. Frequency analysis was used to report responses to fixed-response questions and thematic analysis for open-ended questions. Results indicated that S&C coaches were primarily responsible for delivering S&C programs (60%), and S&C information was predominantly sourced from S&C coaches (43%). Strength and conditioning was deemed very important for randori (78–88%), overall judo performance (67–79%), and judo fitness (62–78%). Similarly, S&C was considered very important for the development of speed and power (76–89%), strength (71–89%), and injury reduction (69–78%). Novel findings were also observed, such as integrating judo-specific training within S&C practice, which may be partly explained by more S&C coaches holding judo belts (67%) than S&C qualifications (11%). This study supports practitioners delivering S&C in judo by offering a base of information to critique or align with their existing S&C practices and perspectives. Furthermore, our results may help identify potential gaps between methods used, proposed guidelines, and actual practice, facilitating the development of research and education resources tailored to the current climate.

Science Students’ Attitudes Towards the Use of Indigenous Language in Understanding Visual Representations
Authors: Ramulumo Moleboheng
Published: March 2024

This study aimed to investigate the attitudes of science students toward the utilization of their indigenous language in comprehending visual representations. A mixed-methods approach was employed to delve into students' perspectives, preferences, and beliefs regarding the medium of instruction in science education, with a specific emphasis on the role played by indigenous languages in the interpretation of visual representations. The study utilized a sequential explanatory research design, initially collecting and analyzing quantitative data, followed by qualitative data to augment the comprehension of the quantitative findings. The findings indicated a marked preference among students for employing English as the medium of instruction in science education, driven by its perceived global significance and potential advantages in accessing scientific resources and opportunities. Furthermore, students who had not been exposed to science education in their indigenous language exhibited negative attitudes toward its utilization. They also repudiated the notion that acquiring science knowledge in their indigenous language would enhance their ability to interpret visual representations effectively. These findings bear implications for the indigenization of curricula and underscore the significance of taking into account students' language preferences and attitudes in the context of science education. Future research should delve further into language choices in various educational settings and refine research instruments to enhance measurement precision. Educators and policymakers would be well-advised to consider students' language preferences to create inclusive and culturally responsive learning environments. This approach provides support to students in enhancing their proficiency in the selected language of instruction.

Deep learning enables early stage prediction of preterm birth using vaginal microbiota
Authors: Karambelkar Kaushik , Baranwal Mayank
Published: March 2024

Graphical abstract

Objective

Preterm birth (PTB) is one of the leading issues concerning infant health and is a problem that plagues all parts of the world. Vaginal microbial communities have recently garnered attention in the context of PTB; however, the vaginal microbiome varies greatly from individual to individual, and this variation is more pronounced in racially, ethnically, and geographically diverse populations. Additionally, microbial communities have been reported to evolve during the duration of the pregnancy, and capturing such a signature may require higher, more complex modeling paradigms. In this study, we develop a neural controlled differential equation (CDE)-based framework for identifying early PTBs in racially diverse cohorts from irregularly sampled vaginal microbial abundance data.

Methods

We obtained relative abundances of microbial species within vaginal microbiota using 16S rRNA sequences obtained from vaginal swabs at various stages of pregnancy. We employed a recently introduced deep learning paradigm known as ‘neural CDEs’ to predict PTBs. This method, previously unexplored, analyzes irregularly sampled microbial abundance profiles in a time-series format.

Results

Our framework is able to identify signatures in the temporally evolving vaginal microbiome during trimester 2 and can predict incidences of PTB (mean test set ROC–AUC = 0.81, accuracy = 0.75, F1 score = 0.71) significantly better than traditional ML classifiers, thus enabling effective early-stage PTB risk assessment.

Conclusion and significance

Our method is able to differentiate between term and preterm outcomes with a substantial accuracy, despite being trained using irregularly sampled microbial abundance profiles, thus overcoming the limitations of traditional time-series modeling methods.

Published: March 2024

Publicly funded research must be accessible to the public in digital format, with or without minimal restrictions. Research also must be reviewed for the accuracy and correctness of the data sources and references used, the accuracy of the concept, and the objectivity of the contents of the paper. This is very closely related to the quality of the research data. Realizing this, the data collected and used in the process—before, during, and after the research—will make researchers and institutions aware of the importance of data literacy. The term data literacy is used in academia to provide a brief description of the ability of individuals to understand basic research concepts, including the quality of research data they possess. Therefore, this study aims to describe the effect of data literacy on research data. This research uses explanatory research with a quantitative approach with 58 respondents from the faculty members of Faculty of Administrative Science, Brawijaya University, Indonesia. The questionnaire was filled out in both digital and printed form. Respondents have a positive tendency toward data literacy. In addition, this is also indicated by the significance of the items, with the most significant items being respondents’ ability to assess the credibility of the data they have. Then, for data quality variables, respondents also have a positive trend, as evidenced by the significance of all items. This trend will have a positive impact on the quality of data from research conducted by respondents. This research is expected to contribute to scientific developments regarding data literacy and the quality of research data, which in this case focuses on research activities conducted by lecturers at universities.
War on Terror’s Impact on the Middle East Civilians in Coldplay’s Orphans Song Lyrics
Authors: Hadikusumo Raden Daffa Akbar , Syahriyani Alfi
Published: March 2024

This article examines the war on terror’s impact in the Middle East civilians on the lyrical content of Coldplay's song "Orphans." The song lyrics feature a fictional narrative about a girl and her father who died due to bomb attacks on their hometown. Utilizing Van Dijk's critical discourse analysis approach, which involves social cognition, social context analysis, and textual analysis, it is deduced that the bombings depicted in the lyrics refer to the bombings in Damascus. This immediately relates to the Global War on Terror and how prejudice against Muslims and the Middle East, even its civilians, overlooks the negative impact that these people suffer. However, social cognition and context analysis help in discovering that Coldplay, a popular Western act composed of white men, did not remain silent about the suffering Muslims and Middle Easterners faced when most Westerners did. Instead, they voiced their perspective on the issue through fictional lyrics that favor Muslims and the Middle East in the ensuing conflict as part of their hope for people to unite regardless of their background and identity.

This research is aimed to reveal the power relation in SMS (Short Service Messages) Phishing. It utilizes the three dimensions of Fairclough CDA perspective; description, interpretation, and explanation. The three functions of SFL (Systemic Functional Linguistics) are practiced for the data analysis. 150 SMS phishing are collected randomly from the authors’ relatives and colleagues. There are two types of SMS Phishing, Complete, and Incomplete. The complete type consists of Opening, Content, and Closing, while the Incomplete with minor Closing. The power relation has been observed from the Opening, Content, and Closing of SMS. The result is shown by the salient descriptions of the data, which are: the exclamation words ‘Selamat’ (65%) in the opening; the second personal pronoun ‘Anda’ (60%), and material process (68%) in the content; imperative moods (88%) and the fake identity of reputable institutions in the closing. The result of the study is interpreted and explained as the data description, that the phishers inserted ‘power’ in the SMS Phishing. The use of ‘Selamat’ explains that the phishers are kind and generous, then “Anda” and the imperative moods indicate that the phishers act as the first person who can lead the targets. In addition, the use of material processes and the fake reputable institution identity explains that the phishers are trustworthy and wealthy people. SMS Phishers employ those language features to make the targets believe them, and SMS becomes a fraud when the targets believe the message is true. CDA and SFL have been used in this study to reveal the intention of SMS phishing from the perspective of linguistics, therefore, the authors attempt to propose CDA and SFL as the analysis tools in the forensic linguistic field.

BACKGROUND AND OBJECTIVES

Nasal intermittent positive pressure ventilation (NIPPV) has been shown to be superior to nasal continuous positive airway pressure (CPAP) postextubation in preterm neonates. However, studies have not permitted high CPAP pressures or rescue with other modes. We hypothesized that if CPAP pressures >8 cmH2O and rescue with other modes were permitted, CPAP would be noninferior to NIPPV.

METHODS

We conducted a pragmatic, comparative-effectiveness, noninferiority study utilizing network-based real-world data from 22 Canadian NICUs. Centers self-selected CPAP or NIPPV as their standard postextubation mode for preterm neonates <29 weeks’ gestation. The primary outcome was failure of the initial mode ≤72 hours. Secondary outcomes included failure ≤7 days, and reintubation ≤72 hours and ≤7 days. Groups were compared using a noninferiority adjusted risk-difference (aRD) margin of 0.05, and margin of no difference.

RESULTS

A total of 843 infants extubated to CPAP and 974 extubated to NIPPV were included. CPAP was not noninferior (and inferior) to NIPPV for failure of the initial mode ≤72 hours (33.0% vs 26.3%; aRD 0.07 [0.03 to 0.12], Pnoninferiority(NI) = .86), and ≤7 days (40.7% vs 35.8%; aRD 0.09 [0.05 to 0.13], PNI = 0.97). However, CPAP was noninferior (and equivalent) to NIPPV for reintubation ≤72 hours (13.2% vs 16.1%; aRD 0.01 [−0.05 to 0.02], PNI < .01), and noninferior (and superior) for reintubation ≤7 days (16.4% vs 22.8%; aRD −0.04 [−0.07 to −0.001], PNI < .01).

CONCLUSIONS

CPAP was not noninferior to NIPPV for failure ≤72 hours postextubation; however, it was noninferior to NIPPV for reintubation ≤72 hours and ≤7 days. This suggests CPAP may be a reasonable initial postextubation mode if alternate rescue strategies are available.

Published: March 2024

La Carrera de Nutrición y Dietética de una Universidad de Chile planteó el fortalecimiento del uso del idioma extranjero inglés en los estudiantes de la carrera mediante el uso de una red social. El objetivo de este estudio fue analizar el nivel de satisfacción por parte de los estudiantes respecto al uso de twitter como herramienta para la aplicación del idioma inglés. Durante el primer semestre del 2023 la aplicación del uso de Twitter se implementó en la asignatura “Emprendimiento y Marketing” en donde la docente a través de un comentario en Twitter relacionaba el contenido disciplinar de la asignatura y posteriormente los estudiantes vertían sus opiniones de acuerdo a lo visto en la clase. Dentro de los resultados, destaca que más del 50% de los estudiantes señaló que la actividad de Twitter les permitió implementar estructuras gramaticales que ya conocían y les permitió utilizar vocabulario ya conocido. En relación al uso del idioma extranjero inglés, los estudiantes pueden practicar sus habilidades lingüísticas en situaciones reales de comunicación, dado que, al interactuar en plataformas como Twitter, son capaces de participar en conversaciones, hacer preguntas, compartir ideas y opiniones acerca de un tema determinado.

Sleep quality is a determining factor for the performance and health of athletes in general. The aim of the present study was to characterize the sleep quality in male and female trained amateur triathletes aged 20 to 59 years. A survey was conducted with 151 trained amateur triathletes, 108 male (38.6 ±8.1 years, triathlon training experience 5.8 ±4.3years, training frequency 6.3 ±0.9 days per week) and 43 female (39.3 ±7.6 years, triathlon training experience 4.8 ±3.3years, training frequency 6.5 ±0.6 days per week). The sleep quality was measured using the Pittsburgh Sleep Quality Index-Br (PSQI-Br), total values below 05 points indicate good sleepers, and values equal to or greater than 05 points indicate poor sleepers. Data from the subscales were analyzed using absolute and relative frequency. The other data in order to characterize sleep quality were analyzed with median, mean, standard deviation, standard error, and 95% Confidence Interval of mean.  Male and female triathletes have poor sleep quality (values equal or greater than 05 points), that can have negative effects on health and performance.  In conclusion, all triathletes regardless of gender and age group have poor sleep quality.
