Radio (1924) de Kyn Taniya. Viajes de un cosmopolita cósmico
Authors: Jalife Jacobo Anuar
Published: February 2023

Radio. Poema inalámbrico en trece mensajes del poeta vanguardista Kyn Taniya apareció en 1924. En ese momento se experimentaba en México un gran entusiasmo por la radio que recién iniciaba sus transmisiones comerciales. Enmarcado por esa euforia radiofónica, el libro de Kyn Taniya es uno de los ejercicios de la vanguardia mexicana más originales de su tiempo. Cercano a los estridentistas, pero distinto en muchas cosas a ellos, Kyn Taniya consigue forjar una voz propia en Radio al estructurar su poemario desde un concepto radiofónico. El poemario plantea un viaje en el que, a partir de una nueva sensibilidad poética moderna, se explora un nuevo mundo creado por la radio.

Simulated Scramjet Shock Train Control Using an All-Coefficient Adaptive Control Approach
Authors: Rockwell Robert , Goyne Chris , Di Long , Lin Zongli , Bakos Robert , Donbar Jeffrey
Published: February 2023

This paper explores the use of dual-mode scramjet shock train control taking an adaptive control approach known as characteristic model-based all-coefficient adaptive control. In this study a simple, semiempirical model of a dual-mode scramjet is developed. This model is suited to computationally efficient control simulation for the assessment of different control approaches. All-coefficient adaptive control is predicted to be as capable of controlling the shock train location, and rejecting disturbances, as a traditional proportional–integral–derivative controller. However, prior knowledge of the scramjet plant is not required for the all-coefficient adaptive control, and it is predicted that this controller is able to better perform when changes in the plant take place. When characteristics of the plant deviate from their nominal values, the adaptive controller can adjust in real time and maintain a stable system response. This is the first time the performance of all-coefficient adaptive control has been examined in the open literature for a dual-mode scramjet. It is also the first time all-coefficient adaptive control of a dual-mode scramjet has been compared to proportional–integral–derivative control. The simple, empirically based plant model of the dual-mode scramjet is also new, and it is well suited to real-time and hardware-in-the-loop control simulations.
Fleet Design Optimization of Package Delivery Unmanned Aerial Vehicles Considering Operations
Authors: Kaneko Shugo , Martins Joaquim R. R. A.
Published: February 2023

The conceptual design process of aircraft starts by deciding the representative mission requirements, followed by optimization of design variables to satisfy the given requirements. However, the appropriate mission requirements are not obvious, especially when designing package delivery unmanned aerial vehicles (UAVs; also called drones). The UAVs must accommodate various combinations of package weights and delivery distances. The complexity increases further when designing a heterogeneous fleet of UAVs that serves a large number of customers. This work addresses this problem by solving coupled design–operation optimization to find optimal mission requirements and optimal UAV designs simultaneously. We formulate this problem as a mixed-integer nonlinear optimization and propose a sequential heuristic algorithm to solve the coupled problem. The benchmark study of the proposed algorithm against a nonconvex branch-and-cut solver shows that the sequential heuristics are effective. We also demonstrate that the simultaneous UAV design and routing optimization reduces the UAV weight across the fleet by more than 12% on average compared to the conventional baseline.

Published: February 2023

Background. The dental health is an integral part of a person's well-being. Students of higher educational institutions comprise a health risk group, since they experience extensive physiological changes and personal socialization. The impact of connective tissue dysplasia on dental health is a relevant research task.

Objective. To analyze the correlation between dental pathology and phenotypic signs of connective tissue dysplasia in first-year students.

Methods. A cross-sectional clinical study of the dental health and phenotypic signs of connective tissue dysplasia was conducted as part of routine dental examination of 263 first-year students of KubSMU, aged 18–23. All participants were divided into 2 groups: group 1 – participants with 0-2 signs of connective tissue dysplasia (n = 108); group 2 – participants with 3 or more signs of dysplasia (n = 155). Statistical analysis of the results was carried out using Microsoft Excel 2010 and Statistica 6.0.

Results. Unsatisfactory and poor oral hygiene levels in the group of participants with connective tissue dysplasia outnumber these levels in the control group by 30% and 22%, with very poor level in the second group 2.3 times higher (p ≤ 0.05). The incidence of noncarious tooth pathology in individuals with dysplasia is 26% higher than in the control group. The caries intensity index in group 2 is almost 20% bigger than in the control group. As expected, the group of participants with no signs of dysplasia revealed better periodontal health, namely 51.85% versus 45.81% (p ≤ 0.05). In terms of mucosal pathology, a statistical significant difference between groups 1 and 2 was noted for traumatic injuries (16.35% and 19.35%, respectively). Dentofacial abnormalities were observed more often in individuals with 3 or more phenotypic signs of connective tissue dysplasia.

Conclusion. Higher morbidity rate of caries and noncarious pathology in the group of first-year students with 3 or more phenotypic signs of connective tissue dysplasia, compared to the group with 0–2 phenotypic manifestations of dysplasia, indicated the need to create a database of the dentofacial profiles of students, develop an algorithm for regular medical check-up of students, as well as provide differentiated preventive and therapeutic measures for students with dysplasia.

Authors: Khasanov M. Z. , Tukhbatullin M. G. , Nasrullaev M. N.
Published: February 2023

Background. Prostate cancer is a frequently diagnosed malignant disease in men. At present transrectal ultrasound is the most common technique for imaging the gland. Traditionally, a combination of grayscale and Doppler modes is used. In order to make transrectal ultrasound of the prostate more informative, the contrast-enhanced techniques are recommended to apply. Contrast-enhanced ultrasound can provide quantitative assessment, which, in turn, increases the objectivity of the results obtained.

Objective. To evaluate potential of contrast-enhanced transrectal ultrasound for differential diagnosis of focal pathology of the prostate.

Methods. A single-center retrospective comparative study of contrast-enhanced transrectal ultrasound of the prostate gland in 66 patients was carried out at the Republican Clinical Oncological Dispansery, the Republic of Tatarstan. The inclusion criteria was the presence of focal pathology in the peripheral zone of the prostate gland. The median age of patients was 67. The following quantitative perfusion parameters were analyzed: time to peak, peak intensity, descending time, area under the curve and an additional index calculated for each of the specified parameters. The resulting enhancement curves were also analyzed by measuring enhancement angles (β) and washout angles (α). SPSS 13.0 (IBM SPSS Statistics, USA) was used for data analysis.

Results. The combination of “angle ß ≥69.5°+ angle α≤69.5°” with sensitivity of 92.7%, specificity 80.0% proved to be the most informative. The sensitivity and specificity of the obtained threshold values “enhancement angle ß≥69.5°” comprised 73.2% and 60.0%, respectively, “washout angle α≤69.5°” — 63.4% and 56.0%, respectively. According to the analysis of perfusion quantitative parameters the test “peak intensity ≥ 34.1 dB” with sensitivity of 75.6%, specificity of 84.0% has the most informative value in the diagnosis of prostate cancer.

Conclusion. Quantitative analysis of contrast-enhanced transrectal ultrasound of the prostate gland provides objectification of the study, and the use of threshold values increases the informativity in the differential diagnosis of focal lesions of the prostate gland.

Published: February 2023

Background. Parkinson's disease is a neurodegenerative disorder that leads to severe disability, especially in its advanced stages. Medical care should be performed in accordance with modern clinical recommendations and standards. Assessment of the quality of medical care in the Russian Federation is carried out via examination of medical documentation by insurance experts regarding compliance with Russian standards and other regulatory documents.

Objective. To study the predictors for unfavorable course of Parkinson's disease based on routine examinations of the quality of medical care.

Methods. The cohort retrospective study included 7,264 examinations of the medical care quality of 1,754 patients with Parkinson's disease for the period from 2011 to 2018 in the Russian Federation. The study focused on two indicators: presence/absence of disease progression and determination/aggravation of a degree of disability or maintenance of the previous social and professional activity. The obtained data were used to develop diagnostic tables with prognostic factors of Parkinson's disease according to A. Wald. Statistical analysis of the results was carried out using Statistica 13 (StatSoft, USA). Results. Diagnostic tables have been developed to determine the prognostic factors affecting the progression of Parkinson's disease and, accordingly, decreasing the degree of social and/ or professional activity and to assess the diagnostic factors when the risk of the disease aggravation will be more than 95%.

Conclusion. The greatest progression of Parkinson's disease (p < 0.05) was observed in the cases of poor collection of complaints, history and clinical evaluation of the patient's condition, inadequate prescription or absence of prescription of levodopa when indicated, as well as defects in the correction of additional disorders. The likelihood of social disadaptation in patients with Parkinson's disease (p < 0.05) was found to be greater in the cases of poor collection of complaints and history, neurological examination and clinical evaluation of the patient's condition as well as inadequate prescription or absence of prescription of levodopa when indicated.

Nanostructured contrast agents are promising alternatives to Gd(III)-based chelates in magnetic resonance (MR) imaging techniques. A novel ultrasmall paramagnetic nanoparticle (UPN) was strategically designed to maximize the number of exposed paramagnetic sites and r1 while minimizing r2, by decorating 3 nm large titanium dioxide nanoparticles with suitable amounts of iron oxide. Its relaxometric parameters are comparable to that of gadoteric acid (GA) in agar phantoms, and the r2/r1 ratio of 1.38 at 3T is close to the ideal unitary value. The good contrast effect was confirmed by T1-weighted MR images of Wistar rats after intravenous bolus injection of UPN. Those results associated with good biocompatibility and a much longer contrast effect before renal excretion indicate its high potential as alternative blood-pool contrast agent to the GA gold standard for MR angiography, especially for patients with severe renal impairment.
φ-Aromaticity in prismatic {Bi 6 }-based clusters: facts and artifacts
Authors: Szczepanik Dariusz , Solà Miquel
Published: February 2023

In a recent paper (Peerless et al. Nat. Chem. (2022) https://doi.org/10.1038/s41557-022-01099-5), the authors isolated the heterometallic cluster containing at its heart the prismatic {Bi6}-based cluster and claimed that it is phi-aromatic. Unfortunately, the authors missed the fact that the electronic structure and bonding in the trigonal prisms like {Bi6} have been known for about 30 years, and has nothing to do with aromaticity. In the present Matters Arising comment we demonstrate that the characteristic phi-type molecular orbital - recognized by the authors as bringing aromatic stabilization (and unusual magnetic-response properties) - actually introduces distortion and destabilizes the prism.
Physics-Inspired Machine Learning of Localized Intensive Properties
Authors: Chen Ke , Kunkel Christian , Cheng Bingqing , Reuter Karsten , Margraf Johannes T.
Published: February 2023

Machine learning (ML) has been widely applied to chemical property prediction, most prominently for the energies and forces in molecules and materials. The strong interest in predicting energies in particular has led to a local energy-based paradigm for modern atomistic ML models, which ensures size-extensivity and a linear scaling of computational cost with system size. However, many electronic properties (such as excitation energies or ionization energies) do not necessarily scale linearly with system size and may even be spatially localized. Using size-extensive models in these cases can lead to large errors. In this work, we explore different strategies for learning intensive and localized properties, using HOMO energies in organic molecules as a representative test case. In particular, we analyze the pooling functions that atomistic neural networks use to predict molecular properties, and suggest an orbital weighted average (OWA) approach that enables the accurate prediction of orbital energies and locations.

Monogenic inherited diseases are common causes of congenital disabilities, leading to severe economic and mental burdens on affected families. In our previous study, we demonstrated the validity of cell-based noninvasive prenatal testing (cbNIPT) in prenatal diagnosis by single-cell targeted sequencing. The present research further explored the feasibility of single-cell whole-genome sequencing (WGS) and haplotype analysis of various monogenic diseases with cbNIPT. Four families were recruited: one with inherited deafness, one with hemophilia, one with large vestibular aqueduct syndrome (LVAS), and one with no disease. Circulating trophoblast cells (cTBs) were obtained from maternal blood and analyzed by single-cell 15X WGS. Haplotype analysis showed that CFC178 (deafness family), CFC616 (hemophilia family), and CFC111 (LVAS family) inherited haplotypes from paternal and/or maternal pathogenic loci. Amniotic fluid or fetal villi samples from the deafness and hemophilia families confirmed these results. WGS performed better than targeted sequencing in genome coverage, allele dropout (ADO), and false-positive (FP) ratios. Our findings suggest that cbNIPT by WGS and haplotype analysis have great potential for use in prenatally diagnosing various monogenic diseases.

Published: February 2023

Flooding is one thing that can slow down the economic pace in the affected area. Bandung is called the city of flowers and the city of fashion because the nickname makes Bandung a city with a variety of fashions growing in multiple places as a starting point for the buying and selling process. Not only did Bandung spawn fashions that became hits every year, but it also had many Meccas of traditional food preparation that were extraordinarily unique and interesting. Creating a flood-prone area model can make it easier to provide information for communities in Bandung Prefecture that belong to flood-prone and non-flood-prone areas. The SVM algorithm is a technique that can be used in the case of classification and regression, which is very popular lately. SVM is in a class with Artificial Neural Networks (ANN) in terms of features and conditions of problems that can be solved, and to be able to increase its accuracy it uses what can be optimized with PSO (Particle Swarm Optimization), where the test data is used BNPB official website data, BPS Bandung District and BMKG processed. The accuracy rate generated by using the SVM algorithm is 85.71% and the generated AUC is 0.841, while the accuracy rate generated by using the PSM-based SVM algorithm is 97.62%. and AUC produced at 1,000.

Kompetisi sains madrasah adalah kompetisi sains yang diadakan oleh kementerian agama untuk menjaring siswa berprestasi pada tingkat madrasah baik madrasah ibtidaiyah, tsanawiyah maupun aliyah. Soal yang disajikan adalah soal yang terintegrasi antara sains dan keislaman. Namun kurangnya perhatian sekolah mengakibatkan banyak siswa masih kurang memahami mengenai kompetisi sains madrasah. Dalam kegiatan ini dilakukan pembimbingan kepada mahasiswa untuk meningkatkan kompetisinya dalam menyelesaikan soal kompetisi sains madrasah terutama dalam bidang fisika. Metode yang dilakukan adalah pembimbingan yang terbagi menjadi empat kegiatan yaitu persiapan, sosialisasi, pelaksanaan dan evaluasi. Kegiatan persiapan dilakukan untuk mengetahui kondisi pendampingan olimpiade di sekolah dan sistematika pembinaannya. Kegiatan sosialisasi dilakukan untuk menentukan sistematika pembinaan seperti waktu dan sistematika pelatihan dan pembinaan. Kegiatan pendampingan dilaksanakan dengan pemberian pre test untuk mengetahui kemampual awal siswa pada setiap materi, pendalaman materi dan selanjutnya diberikan posttest untuk mengetahui adanya peningkatan kemampuan siswa dalam menyelesaikan soal-soal KSM. Kegiatan terakhir adalah evaluasi dan refleksi melalui pemyebaran angket kepada siswa mengenai kegiatan pelatihan. Berdasarkan hasil analisa pretest dan posttest siswa didapatkan bahwa siswa mengalami penigkatan kompetensi untuk semua materi kecuali materi kinematika dan dinamika gerak serta listrik magnet. Hal ini disebabkan kedua materi tersebut termasuk materi yang sulit karena menuntut siswa harus menguasai konsep fisis dan konsep matematis sekaligus sehingga diperlukan metode khusus dalam pengajarannya seperti dengan menggunakan media pembelajaran. Sedangkan angket evaluasi kegiatan menunjukkan bahwa sebagian besar puas dan antusias dalam melaksanakan pembimbingan kecuali dari aspek waktu pembinaan. Hal ini disebabkan karena siswa merasa waktu yang diberikan dalam membahas setiap materi dirasa kurang.

The Oparin Hypothesis is a Falling Star
Authors: Kokić Tonći
Published: February 2023

The Oparin hypothesis from 1936 was a milestone in the origin of life research, making a model that was at least in part empirically testable, and changing the course of life studies from a long tradition of metaphysics to a scientific domain of investigation. His hypothesis is based on the idea of the prebiotic synthesis of macromolecules as a fundamental step on the road to first life. Although the Oparin hypothesis brought fresh ideas and concepts, in its description of the steps in the hypothesized transition from the inorganic to the organic world in detail, today some premises are considered unconfirmed, uncertain, or even rejected. With high respect to its metatheoretical reach and scientific impact on prebiotic chemistry, pushing the origin of first life research into an empirical context, from a contemporary viewpoint, its contribution is highly limited in the area of history of science and history of philosophy (of science).

Gadget melahirkan praktik manipulatif dan melemahkan kekuatan keluarga sebagai pendidik utama dan pertama bagi anak-anaknya. Kondisi ini mendorong pentingnya kehadiran sekolah alternatif sebagai counter-hegemony yang memegang peranan penting untuk membangun pusat legitimasi baru. Sekolah alternatif bisa menyebar dan datang dari mana saja sehingga tidak terpusat pada satu sentral otoritas tertentu.

The parent-teacher interaction has been identified as a critical component in the development of children. Teachers' capacity to educate children is influenced by the level of trust parents have in them. Creating a supportive environment at home and cooperating with the school are essential components of a positive educational experience for all parties involved. Prior research, however, found little parental involvement particularly in establishing a quality relationship with the schools in Indonesian kindergartens. This research aimed to examine Indonesian parents’ degrees of trust and communication toward the teachers in 8 kindergartens in Dairi regency, North Sumatra. In constructing the questionnaire, 9 early childhood education practitioners were invited to make content suggestions before conducting a validity test and reliability through factor analysis. The validity is guaranteed by the Kaiser-Meyer-Olkin Measure result of .872 and Barlett's Test (Chi-Square = 3451.561, df = 406, p 0.05). The reliability was measured using Cronbach's Alpha obtaining an alpha coefficient of .870, indicating good reliability. The findings from the 203 questionnaires consisting of 29 items that were distributed indicate parents’ favorable attitudes toward teachers. Besides, the parent’s background does not reflect their attitudes and practices. Suggestions, including delivering the concept of partnership to the parents and increasing the opportunities of participating in school activities, are provided to promote greater quality of the parent-teacher relationship.

The conversion, known first from the point of view of its theoretical size, and only then by its normative consecration, is generally classified by the literature, but also by the legislature, as concept affiliated to the theory of nullity of the civil act. However, the legal nature of the conversion remains unresolved and unclarified by the doctrine, and sometimes is presented as an exception to the rule or principle quod nullum est, nullum producit effectum, or as way of validation or capitalization of the null legal act, and the string does not end here. For these reasons, and for the intention not to underestimate the importance of correct qualification of the legal nature of the conversion, taking into account that it dictates the legal regime of a concrete concept of law, in the present study we aimed to offer our own vision on this subject.
