Published: February 2022

Sarana dan prasarana olahraga tidak terkelola dengan baik, sehingga menghambat upaya peningkatan prestasi olahraga dan pembudayaan olahraga secara luas. Perlu dilihat secara mendalam apa penyebab tidak terkelolanya dengan baik sarana dan prasarana olahraga tersebut, sebagai dasar pertimbangan kebijakan pengelolaan ke depan. Untuk itu, penelitian ini bertujuan untuk melihat lebih dalam terhadap persoalan pengelolaan sarana dan prasarana olahraga di Indonesia. Penelitian ini adalah penelitian studi kasus pada venue olahraga di lima Provinsi, yaitu: Riau, Sumsel, Jawa Barat, Kaltim, dan DKI Jakarta, yang memang merupakan pusat-pusat sarana dan prasarana terbesar yang ada di Indonesia. Analisisnya menggunakan kerangka kerja Schwarz et al. sebagai landasan teori, kemudian dilengkapi dengan kerangka praktis dari prinsip-prinsip pembangunan sarana dan prasarana olahraga di Australia, dan kerangka kerja pembangunan sarana dan prasarana olahraga di New Zealand. Metode yang digunakan adalah metode kualitatif karena berupaya menjawab pertanyaan bagaimana pengelolaan sarana dan prasarana olahraga. Datanya adalah data sekunder hasil monitoring dan evaluasi ke lapangan, serta dokumen-dokumen terkait lainnya. Dengan menyandingkan beberapa persoalan dari masing-masing provinsi, peneliti berharap mendapatkan letak persoalan sesungguhnya. Di akhir dapat ditemukan bahwa tidak ada pertimbangan jauh ke depan terkait pembangunan sarana dan prasarana olahraga, tidak ada kaitan budaya olahraga masyarakat dengan ketersediaan sarana dan prasarana, dan tidak ada kaitan antara ketersediaan sarana dan prasarana dengan prestasi olahraga provinsi di mana pusat sarana dan prasarana berada. Oleh karena itu dapat disimpulkan bahwa persoalan tidak terawatnya prasarana dan sarana dan pemanfaatan yang tidak optimal lebih disebabkan pada perencanaan pembangunan sarana dan prasarana yang tidak komprehensif dengan memperhatikan budaya olahraga masyarakat setempat, potensi pergerakan event olahraga, dan keterpaduan dengan bidang lainnya seperti aksesibilitas, pariwisata, dan layanan masyarakat lainnya.
TO THE QUESTION OF THE PALEO CULTURE OF THE TURKS
Authors: Huseynova A. I.
Published: February 2022

The article is devoted to the study and description of the natural environment and material culture of the pra-Turkic peoples. The article also examines the different views of famous russian turkologists on the paleoculture of the ancient Turks. An analysis of the meteorological, landscape, floristic and faunistic vocabulary of the Turkic languages allowed russian turkologists to localize the ancestral home of the ancient Turks in the territory from the dry steppes of East Turkestan to the foothills of Altai and mountain forests. The considered scientific articles give representations of Turks about the sky, celestial bodies and phenomena, about climate, landscape terminology, floristic vocabulary, types of settlements and the material life of the early Turks; their dwellings are described. The penetration into the reconstruction of the Turkic pralexicon promotes the further study of the paleoculture, ancestral home and external relations of the Turks on the basis of historical and linguistic data, which does not lose its relevance in the 21st century, contributing to the ethnocultural interaction of Eurasia.

Authors: Daubaraite-Radikiene Ugne , Startiene Grazina
Published: February 2022

For more than 20 years creative industries (CI) have been experiencing increasing attention from both academia and policymakers alike. Capable of creating jobs, invigorating cities and regions, cultural and social life, contributing to the increase in value added, exports and quality of life, numerous studies proved CI to have broad impact on national economy, as evident not only in economic, but also in sociocultural and environmental areas. Authors aim to develop a model of CI impact on national economy integrating economic, sociocultural, and environmental indicators, to create the index for measuring the CI impact on national economy, and to adapt it empirically to the case of the EU countries in 2008 – 2016. Research confirms that the impact of CI is observed in economic, sociocultural, and environmental impact areas. CIIE index allows estimating CI impact on national economy and enables to draw comparisons among the EU countries in 2008 – 2016 based on CI impact on national economy. This study reveals direct dependence between the factors of CI development and CI impact on national economy. With reference to the index describing the conditions of CI development (Global Creativity Index), three clusters of the EU countries were identified using CI impact on national economy (CIIE) index. Clustering confirms that historical, social, economic, and political development of a country determines conditions for CI emergence and development, and, consequently, influences CI impact on national economy.

Published: February 2022

With the advancement in the field of agricultural biotechnology, many genetically modified crops like Bt- cotton, Bt- brinjal have been developed and commercialised to fulfil the need of the world population. Several biosafety concerns viz., risk to human health, risk to environment, ecological concern o has been raised after the rapid commercialization of GM crops every year across the world. As per Convention on biodiversity (CBD), Biosafety is a term used to describe efforts to reduce and eliminate the potential risk resulting from biotechnology and its product. Though many concerns being raised time to time, strict biosafety guideline must be followed before introducing a GM crop in public domain especially in resource poor developing countries.

Published: February 2022

A direct-contact heat and mass exchanger (DCHME) has many advantages over a traditional surface-type heat exchanger, including a high heat transfer coefficient, simplicity of design, and low OPEX and CAPEX. DCHME has a capability to exchange of both heat and mass between the two fluids in the same process. Hence, DCHMEs are widely used in numerous applications in various industries, including the air conditioning industry for cooling and dehumidification and heating and humidification. Based on their structure, DCHME can be categorized into two groups; two fluids direct contact (TFDC) exchanger and two direct contacts with one non-contact fluid (TDCONF) exchanger. This study developed a mathematical model for these two types of exchangers by using a discretized volume with distributed lumped-parameters method instead of using the conventional log mean enthalpy difference (LMHD) and NTU-effectiveness method. Thus, this model can reflect both heat and mass transfer behavior in every spatially distributed physical system. The objective of this study is to develop a mathematical model to be used as a tool for designing DCHME and to be applied as a sub-function of the model predictive control system to predict the effectiveness and dependent parameters of DCHME under the different load conditions and its various input parameters.

Published: February 2022

Groundwater pollution is a major issue in many tropical countries. Governments at all levels are doing little or nothing to supply inhabitants with clean and accessible water, particularly in Nigeria’s Niger Delta region. This study compares differences in water quality parameters in the study area (determine the level of pollutions in the different sites). The investigation made use of standard analytical methodologies. All sampling, conservation, transportation as well as analysis followed the usual APHA procedures (2012). To prevent degradation of the organic substances, all obtained samples were transferred to the laboratory, while keeping in an icebox. Result shows that during wet season, the mean values obtained for water quality parameters were significantly lower in site 9 compared with that obtained in other sites (p < 0.05) with the exemptions of temperature, DO, BOD, COD, acidity, TH, TDS, K, Mg, Zn, Mn, Cd, Pb, Cu, Cr, NH3, NO2, NO3, Ni though slightly lower in most cases in site 9 were not significantly different (p > 0.05) and both alkalinity and SO4 which were significantly higher in site 9 than site 1 (p < 0.05). Result obtained during dry season reveals that there is no remarkable difference in pH, acidity, Pb and Ni between the nine sites (p > 0.05) while other water quality parameters were significantly lower in site 9 than other sites excluding Cl and Mg which were both significantly higher in site 9 than site 8 (p < 0.05). Extra efforts must be made to completely understand the hydrogeochemical properties and appropriateness of groundwater in Nigeria’s core Niger Delta region in order to ensure quality groundwater supply for varied applications. As a result, this research will contribute to the establishment of a quantitative understanding of the effects of many causes on groundwater level changes in every aquifer worldwide. This analysis also reinforces a useful resource for scholars, activists, and public officials looking to improve community awareness, planning, and performance. The verdicts will serve as a valuable guideline for policymakers, the Ministry of Water Resources, and development practitioners, as they highlight the need for appropriate approaches to mitigating toxic elements of water resource contamination in the core Niger Delta in order to protect public health from carcinogenic and non-carcinogenic risks.

Authors: Batra Kavita , Batra Ravi
Published: February 2022

As COVID-19 pandemic gains foothold worldwide, all spheres of life, including daily activities, education, economic, social sectors experienced significant downturns. While COVID-19 affects all population subgroups, college students are particularly vulnerable given their transition to the emerging adulthood surrounded by a broad possibility of future. According to a mounting evidence, college students bear a disproportionate burden of psychosocial morbidities, which can be explained by the uncertainties surrounding the course of the pandemic and the sudden transition to online education. Moreover, many businesses scaled down their recruitment efforts leaving limited employment for students and more competition in the graduate labor market. COVID-19 pandemic has set up a “perfect storm” for students to initiate or relapse of maladaptive behaviors to alleviate their negative feelings. This is where “Deaths of Despair” comes into play. This chapter aims to reflect on the factors contributing to “Deaths of Despair” among college students in the wake of COVID-19 pandemic. Author of this chapter would like to advocate for developing tailored interventions to promote the post-traumatic growth among college students.
Crack Propagation Characterization Applying High Manganese Austenitic Steel to Independent Type B Tank
Authors: Kang Sung-Ku
Published: February 2022

Interest in eco-friendly energy is continuously increasing worldwide. LNG is a good energy source with a continuously increasing use. LNG has a temperature of -165 ℃ and requires low-temperature toughness for the tank material. High manganese austenitic steel has similar mechanical properties to cryogenic materials for LNG, as listed in IGC and IGF codes. High manganese austenitic steel easily satisfies the requirement for low-temperature toughness at cryogenic temperature and exhibits superior performance in terms of yield strength, tensile strength, and elongation, compared to the existing materials mentioned in IGC and IGF codes. In this study, high manganese austenitic steel was applied to an independent type B tank, and compared to the IGC and IGF materials(9 % Ni steel, Sus304, and Al5083). The thickness ratio was reviewed while loading the same LNG fuel. Based on the thickness ratio, the thickness for 9 % Ni steel, Sus304, and Al5083 was calculated for two standard thicknesses of 10 and 20 mm for the high manganese austenitic steel. In accordance with the IGC and IGF codes, the required crack propagation analysis was performed for the independent type B tank, and the resistance to crack propagation for each material was analyzed.

Authors: Nikmanesh Zahra , Khosromehr Lila
Published: February 2022

Background: Multiple sclerosis (MS) is among the most important central nervous system diseases and the most prevalent neurological disease in humans. It is affecting the patient's individual and social performance. Post-traumatic growth (PTG) is the experience of positive personal change due to confrontation with a crisis or traumatic event. Objectives: This study aimed to investigate the relationship of shame, guilt, and self-compassion with PTG in MS patients. Methods: In this descriptive correlational study, the statistical population consisted of all MS patients referred to the MS Societies of Zahedan and Mashhad in 2018. Forty-six patients were selected using a convenience sampling method. Data collection tools were the Post-traumatic Growth Inventory, the State of Shame and Guilt Scale, and the Self-compassion scale. Data analyses were carried out using Pearson correlation and stepwise regression analysis. Results: Shame (r = -0.48, P ≤ 0.00), guilt (r = -0.44, P ≤ 0.002), and both of them (r = -0.49, P ≤ 0.001) were significantly and diversely related to PTG. Also, self-compassion had a significant positive relationship with PTG (r = 0.32, P ≤ 0.01). Stepwise regression analysis indicated that shame and guilt, when entered the equation in the first step, could determine 0.22 of the PTG variance. Conclusions: It is suggested that educational classes and training workshops be held to promote self-compassion and decrease shame and guilt among MS patients.
Aportaciones críticas y despatologizantes en la evaluación psicológica de la diversidad de género
Authors: Argyriou Konstantinos
Published: February 2022

El énfasis de la psicología en la vivencia individual ha generado prototipos idealizados sobre la identidad de género, promulgados a través de las herramientas tradicionales de evaluación psicológica. Las personas transgénero y género no-conforme se han visto presionadas a encajar en las concepciones binarias de dichas evaluaciones, hasta la reciente despatologización aprobada por la Organización Mundial de la Salud. En el presente trabajo teórico se examina cómo se fueron transformando los discursos sobre la diversidad de género y la corporalidad en psicología. Para ello, se apela a cuatro argumentos: la movilización activista contra las definiciones homogéneas de lo trans, la aplicabilidad de las categorías de los sistemas taxonómicos, las resistencias contra las escalas de validez de los test psicométricos y, por último, cuestiones de adaptación intercultural de términos, mediciones y concepciones del cuerpo y la identidad de género.
STUDY OF THE EFFECT OF FIBRE ADDITION ON MODE II FRACTURE OF QUASI-BRITTLE MATERIALS
Authors: SUAREZ GUERRA FERNANDO , FELIPE SESE LUIS ANTONIO , CASTILLA GONZALO FRANCISCO JOSE , DIAZ  GARRIDO FRANCISCO ALBERTO
Published: February 2022

Fracture of quasi-brittle materials, such as concrete or gypsum, has been studied for decades. These studies have given light on the fracture mechanisms as well as on the parameters that drive these processes, allowing producing numerical models that reproduce fracture using tools such as the Finite Element Analysis. On another note, the three possible Modes of fracture that can be identified in the field of Fracture Mechanics, Mode I is very well known, experimentally reproduced and used as the base for most numerical models. Nevertheless, in some cases fracture takes place as a combination of a stress state that induces a fracture mechanism where Modes I and II are involved. In this sense, Mode II fracture has been studied less often, partly because Mode I fracture is more usual, but also because reproducing Mode II experimentally is quite more complex. This study is focused on inducing Mode II fracture on fibre-reinforced gypsum specimens by using two different experimental tests. More specifically, the experimental test proposed by the Japanese standards JSCE and the push-off test are employed. The displacement field is obtained by means of the digital image correlation technique (DIC), which helps to understand how fibres modify the fracture mechanisms of the gypsum matrix when this takes place under Mode II conditions.
NANOSILICA TO MODIFY THE CONSISTENCY OF HIGH COMPRESSIBLE LACUSTRINE CLAYS
Authors: GARCÍA SILVIA , TREJO GARCIA PAULINA , MERLOS ESPERICUETA JOEL , CASTILLO GALVAN ILCE
Published: February 2022

Despite the incredible advances in the most innovative branch of materials science, the nanotechnology research on its application in the geotechnical field is still very limited. Since many minerals in soil and rocks are nanomaterials and their chemical reactions are at the nanoscale, there is a great potential for the use of this important technology in different geotechnical problems. In this study, the stabilization of a soft lacustrine clay using nano-SiO2 is investigated. Through the examination of the Atterberg Limits, as the simplest and most affordable indicators of the consistency of these highly compressible and plastic materials, it is shown that the addition of nanosilica to clay masses substantially modifies their compressibility and resistance as well as their drainage and absorption capacities. When nano-SiO2 is mixed these very plastic and high-water content clays, it transforms them into consistent masses (from very soft to firm). The results presented contribute to widen the knowledge about nano-substances and plastic soils revealing the effects on exceptional lacustrine clays.

Published: February 2022

This paper aims to study the relationship between teamwork competences and successful innovative projects. Empirical insights are provided on this relationship from a study carried out at the School of Mining and Energy Engineering (UPM) in Madrid (Spain). The results of this study establish a strong connection between teamwork and innovative projects using Hierarchical (AHP) and statistical analysis. Throughout this article, the study of successful innovative projects and specifically the role that work teams play in them is proposed to build a model for the creation of work teams that serves as a tool to develop innovative projects of success. The final motivation of this line of research is that if the aspects that define successful innovative projects are known, the model can be fed with the characteristics that these projects include, predict and even prioritize in a portfolio of projects the allocation of resources that will be necessary. The deepening of work teams allows establishing a relationship between successful innovative projects and the composition of these teams, thus being able to propose a team-building model as a diagnostic and planning tool for innovation projects.
As a whole, the paper highlights the importance of team composition and development in order to achieve success in innovative projects.

Published: February 2022

The effects of global urbanization and climate warming on public health, including the health risk caused by the urban heat environment, have drawn extensive attention. Therefore, methods to appraise the spatiotemporal response mechanism of climate warming and the high temperature exposure dose (HTED) of urban residents need to be investigated to achieve sustainable cities. Based on an environmental health risk appraisal model and using the six ring roads in Beijing of China, this study simulated the spatial distribution of future high temperatures in three shared socioeconomic pathways (SSPs), SSP1-2.6, SSP3-7.0, and SSP5-8.5, by determining the correlation between the future mean maximum temperatures and sunny-day mean temperatures. Additionally, the HTED of commuting on foot or by bicycle was assessed based on the point of interest data of subway stations, architectural composition, and traffic surveys. Results demonstrate that during 2020–2040, 66.57% and 50.07% of areas for commuting on foot and by bicycle within the sixth ring road exposed to high temperatures (including low, medium, and high-risk areas). The exposure risks of both commuting methods were concentrated, and the exposure dose was the highest between the fifth and sixth ring roads, whereas the first to fourth ring roads were dominated by non-risk, minimum-risk, and low-risk areas. Moreover, compared with SSP1-2.6 and SSP5-8.5, SSP3-7.0 exhibited low HTED in both commuting methods. The proposed method provides a scientific basis to aid in identifying urban areas with high temperature exposure risk and a reference in assisting the planning of resilient and sustainable cities.

Authors: Sinkovič Lovro , Pipan Barbara , Savić Aleksandra , Vasić Mirjana , Meglič Vladimir
Published: February 2022

Grass pea (Lathyrus sativus L.) is a less common and nearly forgotten crop in many countries, including Slovenia and Serbia. In the present study, genetic analysis and seed characteristics of the collection of 21 grass pea accessions from Southeast Europe were examined. The collection was produced in an open-field experiment in two countries/ locations, i.e. Slovenia/Ljubljana – Jablje and Serbia/ Novi Sad – Rimski Šančevi, during the 2019 growing season. To analyse genetic diversity, specific high polymorphic SSR markers were applied. Initial screening at 12 species-specific SSR loci using binary data revealed great genetic diversity among the grass pea accessions within a collection and three genetic groups were formed. Differences in seed size were measured using descriptors for seed length, width and thickness, and 100-seed weight. Furthermore, several seed colour characters using IBPGR descriptors were visually assessed. The average seed length, width, and thickness of the seeds in the collection were 9.0 mm, 8.3 mm, and 5.4 mm, respectively, while 100-seed weight ranged considerably from 11.7 g to 38.9 g. The highest differences between growing location were seen for 100-seed weight where the coefficient of variability reached 23.5%. The examined grass pea accessions had less monochromatic (one colour) and more colourful seeds, with two or three colours. Based on the seed coat colour accessions were classified into several groups, the most numerous being yellow-white and yellow-green seeds. The data obtained will be the basis for describing Lathyrus sativus genetic resources in databases. Further genetic studies such as next-generation sequencing are suggested.

Published: February 2022

Occupational safety and health measures must be applied by every industry that has at least 100 workers and industries that have a high risk of danger in their work environment. This research aims to examine the influence of a typical leadership style in Indonesia, namely paternalistic leadership, on the safety behavior of employees in the workplace via trust in the supervisor as the mediator refers to social identity theory. Trust in supervisors is conceptualized as separate dimensions of affective trust and cognitive trust. The data were taken using convenience sampling using online survey research conducted in various Indonesian industrial sectors with a high risk of work accidents (N = 300). Data were analyzed using Hayes’ PROCESS macro ver 3.5.3 on SPSS ver. 26. Results showed that affective trust did not mediate the relationship between paternalistic leadership and safety behavior, but cognitive trust mediated the relationship. Results also showed that affective trust and cognitive trust consecutively mediated the relationship between paternalistic leadership and safety behavior
Apakah phubbing mengganggu pertemanan? Hubungan phubbing dengan kepuasan pertemanan pada orang beranjak dewasa

Published: February 2022

This study aims to determine the relationship between phubbing and friendship satisfaction of emerging adults. The respondents of this study were 166 students aged 18-25 years who studied at universities and lived in Jakarta, Depok, Bogor, Tangerang, and Bekasi. They were selected using accidental sampling techniques by meeting with them on their respective campuses. Correlation index calculation showed there was no significant relationship between phubbing and friendship satisfaction (r = .13, p > 0.05). Based on the regression analysis, it was found that phubbing behavior could not predict friendship satisfaction (b = 0.08, t = 1.7, p> 0.05) and it can be concluded that phubbing behavior is not at the level to the point of disturbing the quality of their friendships. Limitations of this study and directions for further research are further discussed.
Surgical management of simultaneous supra- and infratentorial hemorrhages in a pediatric patient with multiple cavernomas
Authors: Tyagi Gaurav , Sikaria Abhay , Birua Gyani Jail Singh , Beniwal Manish , Srinivas Dwarakanath
Published: February 2022

Multiple intracranial cavernomas are rare and occur mostly in familial cases. Clinical presentation with simultaneous rupture of two or more lesions has only been reported in four cases to date. A 15-year-old boy presented with simultaneous right frontal and superior vermian hematomas with hydrocephalus. The patient underwent a ventriculoperitoneal shunt, and his magnetic resonance imaging (MRI) revealed multiple cavernomas with bleed in the above-mentioned locations. The patient underwent a midline suboccipital craniotomy and excision of the cavernoma. The supratentorial lesions were left in situ in lieu of small size, no history of seizures, mass effect, or other neurological deficits. The patient recovered well from surgery with significant improvement in truncal ataxia. He remained asymptomatic for supratentorial lesions at follow-up. Cavernomas should be considered as differential diagnoses in cases of multiple intraparenchymal hemorrhages, especially in pediatric patients. The surgical management should be rationalized based on the lesion location, the eloquence of the surrounding parenchyma, mass effect, and the risks of re-rupture. Due to the rarity of multiple simultaneous hemorrhages, the management of multiple cavernomas remains controversial. The patient’s relatives can be screened with MRI to rule out the familial form of the disease. Strict clinical and radiological follow-up is a must in such patients.

Over the past two decades significant advances have been made in the research of superconducting quantum computing and quantum simulation, in particular of the device design and fabrication that leads to ever-increasing superconducting qubit coherence times and scales. With Google’s announcement of the realization of “quantum supremacy”, superconducting quantum computing has attracted even more attention. Superconducting qubits are macroscopic objects with quantum properties such as quantized energy levels and quantum-state superposition and entanglement. Their quantum states can be precisely manipulated by tuning the magnetic flux, charge, and phase difference of the Josephson junctions with nonlinear inductance through electromagnetic pulse signals, thereby implementing the quantum information processing. They have advantages in many aspects and are expected to become the central part of universal quantum computing. Superconducting qubits and auxiliary devices prepared with niobium or other hard metals like tantalum as bottom layers of large-area components have unique properties and potentials for further development. In this paper the research work in this area is briefly reviewed, starting from the design and working principle of a variety of superconducting qubits, to the detailed procedures of substrate selection and pretreatment, film growth, pattern transfer, etching, and Josephson junction fabrication, and finally the practical superconducting qubit and their auxiliary device fabrications with niobium base layers are also presented. We aim to provide a clear overview for the fabrication process of these superconducting devices as well as an outlook for further device improvement and optimization in order to help establish a perspective for future progress.

The acquisition of geoacoustic parameters is of great significance in studying ocean acoustics. On the basis of deducing the seabed reflection coefficient under the layered absorbing medium, the influence of the absorption coefficient on the seabed reflection coefficient under the condition of large grazing angles is analyzed. The seabed reflection coefficient oscillates at a frequency. When it is equal to the reflection coefficient of the contact interface between seawater and sediment, the corresponding frequency point is defined as the 1/4 oscillation period frequency. At this frequency, the coupling degree between absorption coefficient of sedimentary layer and substrate geoacoustic parameters is less than those at other frequencies. In this paper, a stepwise optimization inversion method for deep water geoacoustic parameters is proposed based on the seabed reflection characteristics of large grazing angles. Firstly, the interference period of the seabed reflection coefficient is extracted by the correlation method, and the sound speed and thickness of the deposited layer are inverted by the interference period. The density is obtained from the inversion result of sound speed combined with Hamilton empirical formula. Secondly, the value of the absorption coefficient of the sedimentary layer is calculated by combining the search boundary of the substrate sound speed. The one-dimensional inversion of the substrate sound speed is realized by using the substrate reflection coefficient at 1/4 oscillation period frequency. Finally, the one-dimensional inversion of the absorption coefficient of the sedimentary layer is realized by using the seabed reflection coefficient at a half-wave layer frequency. The seabed reflection characteristics of large glancing angles are combined with stepwise inversion to reduce the coupling degree of the substrate sound speed and the absorption coefficient of the sedimentary layer. Experimental results show that the geoacoustic parameters retrieved by this method can be effectively applied to the prediction of propagation loss in a certain range under the condition of large grazing angle measurement.

Published: February 2022

Given the purpose of mathematical evolution of Leonardo's sequence, we have the prospect of introducing complex polynomials, bivariate polynomials and bivariate polynomials around these numbers. Thus, this article portrays in detail the insertion of the variable x, y and the imaginary unit i in the sequence of Leonardo. Nevertheless, the mathematical results from this process of complexification of these numbers are studied, correlating the mathematical evolution of that sequence.

The prognostic role of immune cells in amyotrophic lateral sclerosis (ALS) remains undetermined. Therefore, we conducted a longitudinal cohort study including 288 ALS patients with up to 5-year follow-up during 2015–2020 recruited at the only tertiary referral center for ALS in Stockholm, Sweden, and measured the levels of differential leukocytes and lymphocyte subpopulations. The primary outcome was risk of death after diagnosis of ALS and the secondary outcomes included functional status and disease progression rate. Cox model was used to evaluate the associations between leukocytes and risk of death. Generalized estimating equation model was used to assess the correlation between leukocytes and functional status and disease progression rate. We found that leukocytes, neutrophils, and monocytes increased gradually over time since diagnosis and were negatively correlated with functional status, but not associated with risk of death or disease progression rate. For lymphocyte subpopulations, NK cells (HR= 0.61, 95% CI = [0.42–0.88] per SD increase) and Th2-diffrentiated CD4+ central memory T cells (HR= 0.64, 95% CI = [0.48–0.85] per SD increase) were negatively associated with risk of death, while CD4+ effector memory cells re-expressing CD45RA (EMRA) T cells (HR= 1.39, 95% CI = [1.01–1.92] per SD increase) and CD8+ T cells (HR= 1.38, 95% CI = [1.03–1.86] per SD increase) were positively associated with risk of death. None of the lymphocyte subpopulations was correlated with functional status or disease progression rate. Our findings suggest a dual role of immune cells in ALS prognosis, where neutrophils and monocytes primarily reflect functional status whereas NK cells and different T lymphocyte populations act as prognostic markers for survival.

Amino-terminal fragments from proteolytically cleaved gasdermins (GSDMs) form plasma membrane pores that enable the secretion of interleukin-1β (IL-1β) and IL-18. Excessive GSDM-mediated pore formation can compromise the integrity of the plasma membrane thereby causing the lytic inflammatory cell death, pyroptosis. We found that GSDMD and GSDME were the only GSDMs that were readily expressed in bone microenvironment. Therefore, we tested the hypothesis that GSDMD and GSDME are implicated in fracture healing owing to their role in the obligatory inflammatory response following injury. We found that bone callus volume and biomechanical properties of injured bones were significantly reduced in mice lacking either GSDM compared with wild-type (WT) mice, indicating that fracture healing was compromised in mutant mice. However, compound loss of GSDMD and GSDME did not exacerbate the outcomes, suggesting shared actions of both GSDMs in fracture healing. Mechanistically, bone injury induced IL-1β and IL-18 secretion in vivo, a response that was mimicked in vitro by bone debris and ATP, which function as inflammatory danger signals. Importantly, the secretion of these cytokines was attenuated in conditions of GSDMD deficiency. Finally, deletion of IL-1 receptor reproduced the phenotype of Gsdmd or Gsdme deficient mice, implying that inflammatory responses induced by the GSDM-IL-1 axis promote bone healing after fracture.

A 22-year-old man presented with recurrent dizziness and melena. He had no remarkable medical history except for the reflux symptoms for which 18 months of proton pump inhibitor (PPI) intake was required. Gastroscopy revealed a 1-cm, blood-tinged polyp within the gastric rugae. A thickened gastric corpus was observed with a regular arrangement of collecting venules on its surface. Hyperplastic foveolar epithelium was observed in the biopsied specimens from the fundus and gastric rugae. The diagnosis after polypectomy was gastric hyperplastic polyp. Abdominal CT revealed hypertrophy only in the gastric corpus without antral involvement. Increased levels of serum pepsinogen I (>160 ng/mL), pepsinogen II (>50 ng/mL), chromogranin A (>1,800 ng/mL), and gastrin (534 pg/mL) were noted. Three months after PPI discontinuation, CT revealed improvement of the hypertrophic gastric corpus. Serum chromogranin A and gastrin levels decreased to 950.4 ng/mL and 517.0 pg/mL, respectively. Herein, we report a young, Helicobacter pylori-naive patient with prominent hyperplasia in the gastric corpus and a bleeding hyperplastic polyp after long-term PPI use.

Internet traffic classification is fundamental to network monitoring, service quality and security. In this paper, we propose an internet traffic classification method based on the Echo State Network (ESN). To enhance the identification performance, we improve the Salp Swarm Algorithm (SSA) to optimize the ESN. At first, Tent mapping with reversal learning, polynomial operator and dynamic mutation strategy are introduced to improve the SSA, which enhances its optimization performance. Then, the advanced SSA are utilized to optimize the hyperparameters of the ESN, including the size of the reservoir, sparse degree, spectral radius and input scale. Finally, the optimized ESN is adopted to classify Internet traffic. The simulation results show that the proposed ESN-based method performs much better than other traditional machine learning algorithms in terms of per-class metrics and overall accuracy.
