The proper treatment for SCA is chest compressions. The quality of chest compressions is a major determinant of the success of SCA relief. One of the factors that can affect the quality of compression is gender and Body Mass Index. The purpose of this study was to determine the relationship between gender and Body Mass Index on the quality of chest compressions. The research method used descriptive analytic with a cross sectional approach. The sample was 79 respondents. The sampling technique used simple random sampling. Data were collected through measurements of weight, height and quality of compression using the values listed on the Resusci Anne Simulator. Data tested using Chi-Square. Test. The results of the study were 48 (60.8%) respondents had normal BMI, 69 (87.3%) respondents were women and 68 (86.1%) respondents had Bad Performer compression quality. The results of the bivariate test between gender and BMI on the quality of compression have a p-value of 0.003 and a p-value of 0.000, so it can be concluded that there is a relationship between gender and BMI on the quality of chest compressions. Suggestion: Further studies are needed to determine what factors affect the quality of Cardio Pulmonary Resuscitation.Keywords: Body Mass Index; CPR; Gender; Quality of Chest Compression

La educación es un derecho humano fundamental, por consiguiente, los Estados nacionales están en la obligación de garantizar a sus ciudadanos acceso a una educación gratuita y de calidad. Para ello, existen diversas políticas públicas encaminadas a fomentar un proceso educativo de calidad y libre acceso para las juventudes, permitiendo la profesionalización y el desarrollo del talento humano de la nación. El Perú tiene un sistema educativo universitario con bajos índices de calidad, ante lo cual, el presente estudio se trazó como propósito caracterizar el sistema de educación superior peruano, a partir de una investigación teórica-documental. La educación peruana ha presentado un incremento importante durante los últimos años en cuanto a la matrícula de estudiantes, sin embargo, los niveles de deserción permiten evidenciar profundas desigualdades en la sociedad. Resulta urgente construir mecanismos para incrementar los niveles de calidad educativa, así como, fomentar investigación de calidad, procesos de colaboración entre universidades, vinculación con el sector privado, y construir un currículo educativo heterogéneo que evidencia la multiculturalidad nacional.

La creciente desigualdad social en América Latina convoca a la reflexión respecto a las posibilidades tecnológicas de los entornos escolares empobrecidos para asumir retos educativos y de desarrollo. Este trabajo tiene como objetivo reflexionar sobre la gestión de las tecnologías educativas en entornos escolares empobrecidos mediante una revisión documental de aportes teóricos y experiencias significativas en Latinoamérica. Los resultados revelan las posibilidades tecnológicas de estrategias educativas gestionadas desde la interacción humana y donde participan estudiantes, docentes, padres y comunidad como sujetos interesados en las trayectorias de los estudiantes por los niveles del sistema educativo. La comunicación dialógica, las articulaciones intra e inter institucionales con apoyo en las entregas educativas y en el acompañamiento y vinculación entre los niveles educativos constituyen tecnologías que reivindican los contenidos en los entornos escolares empobrecidos. Se concluye que la gestión de las tecnologías educativas esbozadas al descansar en el trabajo humano y los registros físicos tienen mayores posibilidades de gestión en entornos escolares empobrecidos.

Se plantea como finalidad del estudio determinar la influencia de la motivación en las estrategias de aprendizaje asumidas en entornos virtuales de una institución educativa privada ubicada en Lima durante el año 2020. El estudio se proyecta como una investigación con enfoque cuantitativo, sustantivo, causal, hipotético deductivo, cuya muestra fue de 120 estudiantes extraídos de una población de 240 en total . A partir de la construcción de tres cuestionarios, aplicados mediante encuestas, se obtienen datos que fueron procesados mediante la ecuación estructural. Se evidencia que la motivación y las estrategias de aprendizaje se relacionan positivamente (.806***), sin embargo, el uso del entorno virtual está determinado por las estrategias (.706***) y no por la motivación para el aprendizaje (p=.345). Esta situación ocurre porque aún está presente en los estudiantes la modalidad presencial como la única forma de aprendizaje, prefieren el uso del material en físico, consideran importante el contacto con los compañeros y docente, afirman que aprenden cada día, pero no lo suficiente para una evaluación. El aula virtual fue configurada en la inmediatez ante la declaración de la pandemia, no obstante, no se realizó el control de calidad, ocasionando casos de insatisfacción. Es importante la capacitación continua y la atención a las inquietudes, así como la retroalimentación de las tareas por los docentes.

Using HARPS-N, CARMENES, and RVs spanning a total of 25 yr, we further refine the planet candidate parameters to P = 24.422 ± 0.014 days, K = 3.19 ± 0.27 m s−1, M sin i = 10.6 ± 1.2M

This system adds to the number of exoplanets detected in binaries with M-dwarf members and serves as a case study for planet formation in stellar binaries.
Two-point Correlation Function Studies for the Milky Way: Discovery of Spatial Clustering from Disk Excitations and Substructure
Authors: Hinkel Austin , Gardner Susan , Yanny Brian
Published: January 2023

We introduce a two-particle correlation function (2PCF) for the Milky Way, constructed to probe spatial correlations in the orthogonal directions of the stellar disk in the Galactic cylindrical coordinates of R, ϕ, and z. We use this new tool to probe the structure and dynamics of the Galaxy using the carefully selected set of solar neighborhood stars (d ≲ 3 kpc) from Gaia Data Release 2 that we previously employed for studies of axial symmetry breaking in stellar number counts. We make additional, extensive tests, comparing to reference numerical simulations, to ensure our control over possibly confounding systematic effects. Supposing either axial or north–south symmetry, we divide this data set into two nominally symmetric sectors and construct the 2PCF, in the manner of the Landy–Szalay estimator, from the Gaia data. In so doing, working well away from the midplane region in which the spiral arms appear, we have discovered distinct symmetry-breaking patterns in the 2PCF in its orthogonal directions, thus establishing the existence of correlations in stellar number counts alone at subkiloparsec length scales for the very first time. In particular, we observe extensive wavelike structures of amplitude greatly in excess of what we would estimate if the system were in a steady state. We study the variations in these patterns across the Galactic disk, and with increasing ∣z∣, and we show how our results complement other observations of non-steady-state effects near the Sun, such as vertical asymmetries in stellar number counts and the Gaia snail.

We report the first laboratory experiment dealing with the interaction of a cosmic dust simulant with positrons emitted from a 22Na radioisotope. Measurements of a charge of micrometer SiO2 dust grains with an accuracy of one elementary charge e revealed +1 e steps due to positron annihilation inside the grain. The observed average rate of these charging events agrees well with prediction of a model based on the continuous slowing down approximation of energetic of positrons inside the grain. Less frequent charge steps larger than +1 e were attributed to emission of secondary electrons during positron slowing down. The determined coefficient of secondary electron emission is approximately inversely proportional to the grain radius. The experimental results led us to the formulation of a possible scenario of interstellar dark clouds charging.
Locating Type II-P Supernovae Using the Expanding Photosphere Method. I. Comparing Distances from Different Line Velocities
Authors: Mitchell R. C. , Didier B. , Ganesh S. , Acharya K. , Khadka R. , Silwal B.
Published: January 2023

W present the results of our work testing a version of the Expanding Photosphere Method (EPM) used by Hamuy et al. and Dessart & Hillier to calculate distances to Type II-P supernovae, accounting for the deviations of their luminosities from those of true blackbodies. This method was applied to a sample of supernovae with data sets covering different postexplosion time periods. Different spectral lines in visible wavelengths—Hβ, He i, Fe ii, Sc ii, Na i, and Ba ii—are used to measure the expansion velocity with the goal of determining the species that produces the most reliable distance determination when combined with the blackbody temperature of the effective photosphere. This research suggests that Hβ, Fe ii, and Ba ii lines are most likely to yield accurate distances when combined with blackbody temperature, and provides further evidence of EPM’s effectiveness as an indicator of distance, provided we have a minimum of three data sets covering a broad range of postexplosion phases of the supernova.
High-energy Neutrino Emission from Espresso-reaccelerated Ions in Jets of Active Galactic Nuclei
Authors: Mbarek Rostom , Caprioli Damiano , Murase Kohta
Published: January 2023

We present a bottom-up calculation of the flux of ultrahigh-energy cosmic rays (UHECRs) and high-energy neutrinos produced by powerful jets of active galactic nuclei (AGNs). By propagating test particles in 3D relativistic magnetohydrodynamic jet simulations, including a Monte Carlo treatment of sub-grid pitch-angle scattering and attenuation losses due to realistic photon fields, we study the spectrum and composition of the accelerated UHECRs and estimate the amount of neutrinos produced in such sources. We find that UHECRs may not be significantly affected by photodisintegration in AGN jets where the espresso mechanism efficiently accelerates particles, consistent with Auger’s results that favor a heavy composition at the highest energies. Moreover, we present estimates and upper bounds for the flux of high-energy neutrinos expected from AGN jets. In particular, we find that (i) source neutrinos may account for a sizable fraction, or even dominate, the expected flux of cosmogenic neutrinos; (ii) neutrinos from the β-decay of secondary neutrons produced in nucleus photodisintegration end up in the teraelectronvolt to petaelectronvolt band observed by IceCube, but can hardly account for the observed flux; (iii) UHECRs accelerated via the espresso mechanism lead to nearly isotropic neutrino emission, which suggests that nearby radio galaxies may be more promising as potential sources. We discuss our results in light of multimessenger astronomy and current/future neutrino experiments.

Les États du Golfe : nouveaux acteurs de la stabilisation du Sud ?
Authors: Berger Chloé
Published: January 2023

Depuis la fin des années 2010, les États du Conseil de Coopération de Golfe ont gagné une influence certaine au sein du bassin méditerranéen. Les rapports de force en Méditerranée sont désormais tributaires des rivalités de puissance qui traversent cette région (Iran/CCG ; Qatar/Émirats-Arabie saoudite) longtemps considérée « en marge » du monde arabe. En raison de leurs « singularités », les États du Golfe ont très tôt été poussés à développer des instruments d’influence visant à compenser et dépasser leurs faiblesses naturelles par des effets de levier (alliances avec des partenaires puissants, leadership idéologique, levier du pétrole, assistance au développement et aide humanitaire, etc.). Dans ce contexte, les pétromonarchies ont progressivement investi les champs de la reconstruction et de la stabilisation. Si la différenciation de leurs registres d’influence leur a permis de gagner un rayonnement croissant sur les affaires de la région MENA, elle les a également entraînées dans une concurrence qui pourrait se révéler insoutenable à terme.
Derrière le masque du consensus… Analyse des divergences syndicales autour des enjeux de santé mentale au travail
Authors: Brugière Fabien , Fortino Sabine , Goussard Lucie , Tiffon Guillaume
Published: January 2023

Cet article questionne le positionnement revendicatif des organisations syndicales de salariés sur les enjeux de santé mentale au travail en mobilisant les principaux résultats d’une enquête sociologique menée, au niveau confédéral, auprès des responsables de la santé au travail et de la formation d’une dizaine de syndicats, ainsi que sur une étude documentaire (documents de congrès, presse syndicale, sites internet). Il montre qu’aussi structurantes que puissent être les lignes de fracture « traditionnelles » instituées sur les enjeux économiques comme l’emploi ou les salaires, ces oppositions s’avèrent peu opérantes pour comprendre les divergences et convergences en matière de santé mentale, aussi bien dans la manière de désigner les facteurs explicatifs de ces risques de santé – notamment le rôle joué par l’organisation du travail et le management – que de nommer les risques eux-mêmes. Ces clivages ressurgissent toutefois nettement concernant la définition des modalités d’action et, surtout, des finalités poursuivies à travers elles. Les positions syndicales s’ordonnent alors selon un continuum allant du projet de convergence avec les employeurs à la nécessité de construire des rapports de force pour obtenir des avancées sur le sujet.
Vers une prise en compte des inégalités sociales dans les modèles de dépenses de santé
Authors: Detève Louise , Courtejoie Noémie , Pollak Catherine
Published: January 2023

Cet article part du constat que le rôle des inégalités sociales dans la variabilité des dépenses de santé reste mal connu. Ces inégalités gagnent à être intégrées aux modèles de dépenses de santé qui ont vocation à en identifier les principaux déterminants. L’ajustement au risque, concept en développement, est l’outil privilégié pour cette démarche, parce qu’il permet une mesure individualisée des disparités qui expliquent les dépenses de santé. La prise en compte des inégalités sociales dans les modèles d’ajustement au risque peut présenter des avantages à des fins d’analyse et d’allocation des ressources, comme en témoignent les modèles existants et leur utilisation. Néanmoins, l’inclusion de déterminants sociaux dans ces modèles pose non seulement des difficultés techniques, mais également éthiques dans le cadre de leur utilisation pour réformer les paiements des professionnels de santé.
L’accompagnement à l’emploi en temps de dématérialisation
Authors: Codron Emilia
Published: January 2023

Le service public de l’emploi (SPE) n’échappe pas à la tendance massive à la dématérialisation des services publics. Les prestations d’accompagnement proposées par le SPE, Pôle emploi en tête, passent de plus en plus par des vecteurs numériques. Dans cet article, sont explorées les incidences de cette dématérialisation sur la réception de ces accompagnements par les demandeurs d’emploi les plus éloignés du numérique. Ces derniers en sont insatisfaits et/ou se retrouvent dans l’incapacité de se conformer aux attentes de leurs conseillers. Ils se tournent alors vers d’autres professionnels, en l’occurrence les animateurs du dispositif Mobilisation orientation vers l’emploi qui travaillent dans les quartiers prioritaires marseillais, que nous avons étudiés entre 2016 et 2021.
A high-order linearly implicit energy-preserving Partitioned Runge-Kutta scheme for a class of nonlinear dispersive equations
Authors: Cui Jin , Fu Yayun
Published: January 2023

In this paper, we design a novel class of arbitrarily high-order, linearly implicit and energy-preserving numerical schemes for solving the nonlinear dispersive equations. Based on the idea of the energy quadratization technique, the original system is firstly rewritten as an equivalent system with a quadratization energy. The prediction-correction strategy, together with the Partitioned Runge-Kutta method, is then employed to discretize the reformulated system in time. The resulting semi-discrete system is high-order, linearly implicit and can preserve the quadratic energy of the reformulated system exactly. Finally, we take the Camassa-Holm equation as a benchmark to show the efficiency and accuracy of the proposed schemes.
Between Dogma and Data: Wilhelm Schmidt and the Afterlives of 19th-Century Ethnolinguistics
Authors: Solleveld Floris
Published: January 2023

Father Wilhelm Schmidt SVD (1868-1954) was one of the great linguistic and ethnological information hoarders of the early 20th century. Through the missionary Society of the Divine Word, he coordinated an army of trained fieldworkers who supplied him with information for his twelve-volume synthesis of world religions, his atlas of the world’s languages, and the journal Anthropos. Schmidt saw himself as practicing Catholic modern science, based on historical criticism and observational data. His guiding tenet was that language structures and material culture were linked to intersecting patterns of original Kulturkreise (cultural spheres), each with their own form of primeval monotheistic religious awareness. In other words, Schmidt sought to confirm Catholic dogma through data; a confirmation bias that mainly taints his ethnological work. This article investigates to what extent it also informed his more technical linguistic work, and how the two are interrelated.
Circulations transnationales en matière d’éducation (XIXe-XXe siècles) : note de synthèse des travaux d’un champ de recherche en expansion
Authors: Alix Sébastien-Akira , Kahn Pierre
Published: January 2023

Depuis le dernier quart du XXe siècle, de nombreux chercheurs et historiens se sont efforcés d’historiciser l’émergence, la constitution et le déploiement d’un espace de circulations – des acteurs, objets, savoirs, réseaux, etc. – entre les différentes régions du monde. Ces recherches ont contribué à l’émergence de ce qu’il est désormais d’usage d’appeler le transnational turn en sciences humaines et sociales. Dans le champ de l’histoire de l’éducation, cette perspective transnationale a connu un essor important en France ces dernières années. Sans prétendre à l’exhaustivité, cette note de synthèse entend mettre en lumière l’intérêt et les enjeux de ces recherches qui insistent sur l’importance des circulations transnationales pour comprendre les réalités éducatives aux XIXe et XXe siècles, en particulier dans l’espace transatlantique.

Les échanges commerciaux à la surface du globe ont conduit à l’introduction des espèces végétales et animales dans de nouveaux territoires. En franchissant les barrières écosystémiques (environnementale, reproductive et de dispersion), certaines d’entre elles parviennent à devenir invasives. Spathodea campanulata, mieux connu sous le nom d’arbre tulipe est une espèce originaire d’Afrique introduite à des fins ornementales. C’est une espèce qui représente une grande menace écologique ; elle a envahi les forêts secondaires mésophiles des îles du Pacifique (les îles Cook, Fidji, Polynésie française, Guam, Hawaï, Nouvelle-Calédonie et Vanuatu) mais aussi Porto Rico, le Brésil et l’Australie. En Martinique, l’espèce semble avoir pris une ampleur considérable dans le milieu naturel. Autrefois plantée comme arbre d’ornement, l’espèce s’échappe aujourd’hui des jardins et parcs ornementaux et colonise peu à peu les formations végétales ouvertes. Une étude floristique sur le territoire martiniquais nous a permis de décrypter les principaux traits de vie de Spathodea campanulata.
Multiple Nontrivial Solutions to a Nonlocal Critical Exponent Problem
Authors: Soni Amita , Choudhuri D.
Published: January 2023

The authors use the manifold technique to demonstrate that the issue combining a nonlinear integro-differential operator and a term with critical exponent has three nontrivial weak solutions. The operator considered in the problem covers the case of the fractional p-Laplacian operator and is possibly degenerate. The outcomes include a sign-changing solution and a positive and a negative solution. Also, presence of critical exponent term increases the complexity of the problem as compactness property fails in this case.

A Machine Learning-Based Anomaly Detection Method and Blockchain-Based Secure Protection Technology in Collaborative Food Supply Chain
Authors: Chen Yuh-Min , Chen Tsung-Yi , Li Jyun-Sian
Published: January 2023

The complexity of the collaborative food supply chain has resulted in the frequent occurrence of food safety incidents, which harm people's health and life. Therefore, the maintenance of food safety has become a key value. This study expects to solve the food safety problem and bring more benefits to people using intelligent systems. To meet the safety needs of the collaborative food supply chain, this study designed a food safety protection system architecture which collects the supply and sales data of various suppliers, as well as the data of equipment used in production. The architecture can carry out anomaly detections with machine learning to make a preliminary judgement on whether a problem has occurred in this batch of food during the transaction, and then implement in-depth anomaly detections with the supplier's equipment to determine the stage at which this problem occurred. The proposed system can help food operators achieve effective food monitoring, prediction, prevention, and improvement, thereby improving food safety.
Optimized Deep Neuro Fuzzy Network for Cyber Forensic Investigation in Big Data-Based IoT Infrastructures
Authors: Thapaliya Suman , Sharma Pawan Kumar
Published: January 2023

Forensic skills analysts play an imperative support to practice streaming data generated from the IoT networks. However, these sources pose size limitations that create traffic and increase big data assessment. The obtainable solutions have utilized cybercrime detection techniques based on regular pattern deviation. Here, a generalized model is devised considering the MapReduce as a backbone for detecting the cybercrime. The objective of this model is to present an automatic model, which using the misbehavior in IoT device can be manifested, and as a result the attacks exploiting the susceptibility can be exposed by newly devised automatic model. The simulation of IoT is done such that energy constraints are considered as basic part. The routing is done with fractional gravitational search algorithm to transmit the information amongst the nodes. Apart from this, the MapReduce is adapted for cybercrime detection and is done at base station (BS) considering deep neuro fuzzy network (DNFN) for identifying the malwares.
Mechanical QT and JT intervals by M-mode echocardiography
Authors: Rad Elaheh Malakan , Ilali Hamidreza Mirzaei , Majnoon Mohammad-Taghi , Zeinaloo Aliakbar
Published: January 2023

Background :

Congenital long QT syndrome (CLQTS) is a life-threatening ion channelopathy leading to syncope and sudden death. Early diagnosis during the prenatal period and timely intervention can prevent sudden cardiac death and catastrophic consequences of this genetic ion channelopathy. Fetal magnetocardiography and fetal electrocardiography (ECG) enable the measurement of fetal QT and JT intervals, but their inherently technically challenging and/or resource-intensiveness nature preclude their routine clinical application. On the other hand, the high-temporal resolution of M-mode echocardiography makes it a well-suited and widely available modality for the measurement of cardiac events.

Aims and Objectives :

We aimed to investigate the mechanical counterparts of the electrical QT and JT intervals on M-mode echocardiographic images of the tricuspid, mitral and aortic valves, and aortic wall.

Methods :

We performed a prospective study on consecutive children referred to the outpatient pediatric cardiology clinic at a tertiary children's hospital. We defined M-mode echocardiographic landmark points on tracings of tricuspid annular planar systolic excursion, mitral and aortic valves, and aortic wall with simultaneous electrocardiographic recording. We measured the mean±SD of the absolute time difference and RR-adjusted time difference in cases with non-coincident ECG events and echocardiographic landmarks.

Results :

Fifty healthy children were enrolled in the study. In 47 (94%) out of the 50 children, Q was coincident with the starting point of the tricuspid annular plane systolic excursion. In all children, the Q was coincident with the mid-point of the A-C line of the mitral valve. In 38 (76%) cases, there was a bump on the anterior wall of the aortic root immediately before the change in the slope of the aortic wall. This was coincident with the Q wave in 100% of cases. In all cases, the J point coincided with the point of acceleration of velocity on TAPSE. In all children, the J point coincided with the initial maximal opening of the aortic cusps. The end of the T wave occurred coincident with the peak of the tricuspid annular planar systolic excursion in 47 children (94%). In 48 children (96%), the end of the T wave coincided with the aortic cusps' closure point.

Conclusions :

Based on our findings, we propose to measure the averaged mechanical QT and JT intervals by using an angled M-mode tracing of the aortic and mitral valve in five consecutive beats in the parasternal long-axis view. This is the first study on mechanical QT and JT intervals in healthy children. The study opens the horizons into the in-utero diagnosis of congenital long QT syndrome by measuring fetal QT and JT intervals using the widely available M-mode echocardiography
Advanced imaging and digitization of preserved heart specimens using virtual reality – A primer
Authors: Vegulla Ravi V. , Tandon Animesh , Rathinaswamy Jebaraj , Cherian Kotturathu Mammen , Hussain Tarique , Murala John S.
Published: January 2023

Introduction :

Preserved congenital heart specimens are an important component of training professionals working with children and adults with congenital heart disease. They are curated in few institutions worldwide and not freely accessible. This was a proof-of-concept project to explore the use of advanced cardiac imaging modalities (computed tomography [CT] and magnetic resonance imaging [MRI]) and virtual reality (VR) simulation to assess the feasibility and identify the best method of imaging curated cardiac pathology specimens.

Methods :

Seven specimens in glass jars with formalin, with varied anatomic lesions, from a curated collection were imaged using MRI and high-dose CT to compare the fidelity of models created via each modality. Three-dimensional (3D) models were created and loaded into a VR headset and viewed in virtual space. Two independent physicians performed a “virtual dissection” and scored the resultant models.

Results :

The highest fidelity and tissue characterization of more delicate structures was achieved with T2 spoiled gradient-echo sequences on MRI (median score of 4 out of 5). CT (median score of 3), while excellent for external anatomy, lost some fidelity with delicate internal anatomy, even at high-radiation doses. No specimens were damaged.

Conclusions :

We believe that in vitro heart specimens can be easily scanned with high fidelity at a relatively low cost, without causing damage, using high-dose CT and MRI. The ability to “walk through” different chambers of the heart makes the understanding of anatomy easy and intuitive. VR and 3D printing are technologies that could be easily adapted to digitize preserved heart specimens, making it globally accessible for teaching and training purposes.

Published: January 2023

Right-to-left shunt due to abnormal systemic venous drainage to the left heart is among the causes of hypoxemia following Fontan operation. There are conflicting data regarding the closure of the venovenous collaterals (VVCs) post-Fontan, showing decreased survival in older patients. In a child with visceral heterotaxy, we describe a rare fistula draining a right-sided hepatic vein into hepatic venous plexus and a right-sided pulmonary venous atrium. The patient presented with severe hypoxemia post-Fontan and underwent fistula occlusion with AMPLATZER™ Vascular Plug II, successfully improving hemodynamic status with resolution of the hypoxemia. Younger patients with cyanosis due to VVCs may benefit from percutaneous occlusion post-Fontan.

Devonian palynoevents in the circum-Arctic region
Authors: Marshall John E.A. , Mangerud Gunn , Bringué Manuel , Bujak Jonathan
Published: January 2023

Devonian strata of the present-day Arctic contain abundant and diverse assemblages of terrestrial palynomorphs, particularly from Middle and Upper Devonian sections; few intervals of Lower Devonian and Silurian strata have been palynologically studied, and these demonstrate strong palynofloral similarities across the region. Based on published records, we present a compilation of six last occurrence events (LOs), 44 first occurrence events (FOs) and one acme event that have proven of value in correlation in the present-day Arctic. Although their chronostratigraphic resolution is relatively low, and a scarcity of independent age control hampers precise age assignments, palynology is the only biostratigraphic discipline available for confident chronostratigraphic correlation of most Arctic Devonian strata.

We introduce a new method to evaluate algebraic integrals over the simplex numerically. This new approach employs techniques from tropical geometry and exceeds the capabilities of existing numerical methods by an order of magnitude. The method can be improved further by exploiting the geometric structure of the underlying integrand. As an illustration of this, we give a specialized integration algorithm for a class of integrands that exhibit the form of a generalized permutahedron. This class includes integrands for scattering amplitudes and parametric Feynman integrals with tame kinematics. A proof-of-concept implementation is provided with which Feynman integrals up to loop order 17 can be evaluated.

OBJECTIVES: In Korea, a national coronavirus disease 2019 (COVID-19) vaccination program was implemented, including 4 vaccines against COVID-19. A text messaging-based survey, in addition to a passive adverse event reporting system, was launched to quickly report unusual symptoms post-vaccination. This study compared the frequency of adverse events after COVID-19 vaccination based on the vaccine type and the type of 2-dose regimen (homologous or heterologous).METHODS: Self-reported adverse events were collected through a text-message survey for 7 days after each vaccination. This study included 50,950 vaccine recipients who responded to the survey at least once. Informed consent to receive surveys via text was obtained from the vaccine recipients on the date of first vaccination.RESULTS: The recipients of mRNA vaccines reported local and systemic reactions 1.6 times to 2.8 times more frequently after dose 2 than after dose 1 (p<0.001), whereas ChAdOx1-S recipients reported significantly fewer local and systemic reactions after dose 2 than after dose 1 (p<0.001). Local and systemic reactions were approximately 2 times and 4 times more frequent for heterologous vaccination than for BNT162b2/BNT162b2 and ChAdOx1-S/ChAdOx1-S regimens, respectively. Young individuals, female, and those receiving heterologous vaccine regimens including ChAdOx1-S/BNT162b2 vaccines reported more adverse events than older participants, male, and those with homologous vaccine regimens.CONCLUSIONS: Although a heterologous regimen, youth, and female sex were associated with a higher risk of adverse reactions after COVID-19 vaccination, no critical issues were noted. Active consideration of heterologous schedules based on the evidence of efficacy and safety appears desirable.

Two identical dinoflagellate cell specimens were found in a seawater sample collected from Tanjung Pasir Beach (TPB; 6.01 S, 106.8 N), Banten, Indonesia and subjected to morphological characterization light microscopy (LM). The cells measured 71.97–72.86 µm long and 52.55–52.76 µm wide, fusiform or biconical-shaped, with tapered apical and antapical horns. A sharp and pointy spine was present at the antapex. The Kofoidean thecal plates arrangement pattern of the specimens was formulated as Po, 4', 2a, 7'', 3(?)c, 4s, 5''', 2''''. Based on this thecal plate tabulation formula combined with the cell morphologies, the specimens conformed to the original description of, and therefore identified as, Protoperidinium abei (Paulsen) Balech. This study constitutes the first record of P. abei in Indonesia and the first to illustrate and describe its detailed morphology using LM.

Association studies of SNPs have become very important in determining how genetic variants are linked to complex diseases, quantitative traits, and physiological responses. Genetic polymorphisms in the GLP-1R gene have potentially decreased protein stability and are associated with many diseases, especially diabetes and obesity. This study aimed to screen the expression and investigate the genetic polymorphism of the GLP-1R by using several beneficial bioinformatics tools. We observed database Ensembl, GTEx portal, and KEGG to identify the structure, expression, and molecular pathway of GLP-1R. In silico computational methods (SIFT, PolyPhen v2, PROVEAN, and PhD-SNP) were used to identify nsSNPs of the GLP-1R that potentially influence protein structure and function. I-Mutant was used to investigate possibly damaging nsSNPs, while GeneMANIA was used to investigate GLP-1R gene-gene interactions. GLP-1R is localized on chromosome 6p21, contains 13 exons, and has the regulation variant (CTCF, promotor, enhancer, and promotor flank region). GLP-1R is highly expressed in the pancreas to stimulate glucose-dependent insulin secretion and suppress glucagon secretion. Seven nsSNPs of the GLP-1R gene were found to be potentially deleterious: rs10305421, rs201672448, rs10305492, rs2295006, rs6923761, rs1042044, rs140642887, and rs10305510. I-Mutant server showed that nsSNPs rs140642887 was unstable, decreased GLP-1R protein stability, and impaired other genes' interaction and function (SP1, SP3, GNAS, and GCG). This study is the first in silico analysis of the polymorphic GLP-1R gene, and will serve as a great resource for developing precision medications to treat diseases associated with these polymorphisms.

Rice cultivation as intercropping in plantations is a potential approach to increase land resource efficiency. Implementation of rice intercropping would require genotypes adapted to shaded environments. This study aimed to clarify the interaction of genotype and environment on agronomic characteristics of upland rice grown under intercropping system and to identify suitable genotypes for this particular cropping system. Multi-location trials evaluated twelve upland rice lines and two check varieties in eight upland sites during the wet season (WS) 2015-2016. Rice was grown as intercropping in six sites and as monoculture in two sites. Rice as intercrop was cultivated in between plantations of tall coconut, rambutan, teak, albizia, and natural rubber. The result of this study revealed that the interaction between genotype and environment was significant for all agronomic characteristics. The genotype B12056F-TB-1-29-1 was the best performer when grown as intercropping in Subang and Indramayu, with shading intensities of 65% and 44%, respectively. The genotype B11908F-TB-3-WN-1 was the best yielder in Cianjur and Lampung Tengah, which had 37% and 54% shading intensity, respectively. The genotype B12825E-TB-2-4 was the best performer in Lampung Timur with shading intensity of 45%, while Jatiluhur was the best genotype in Banyumas with shading intensity of 82%. The yield of rice genotypes grown as monocultures was higher than as intercropping. Among the genotypes, B12056F-TB-1-29-1 showed the highest yield across sites. Stable and high-yield genotypes identified from this study are expected to be adopted by farmers for intercropping rice cultivation.

Red amaranth (Amaranthus cruentus L.) is a fast-growing and nutritious leafy vegetable. The seed population density needs to be known appropriately to obtain the optimal yield of marketable sizes plants. The residue of black soldier fly (BSF) larvae culture has been recognized as a potential source of nutrients for cultivating red spinach plants. This study was designed to search for the best combination of plant population density and BSF concentration to obtain the optimal marketable yield of the red amaranth plant. In addition, an accurate leaf area estimation of the red amaranth plant was also developed using leaf dimensions as a predictor with several regression models. Two experiments were conducted. Firstly, the BSF residue was applied at a high rate (up to 50%) using a floating culture system. Application of the residue at the rate of 30% and higher significantly inhibited the growth of the red amaranth. Secondly, the application rate was reduced to 10% and 20%, and the experiment was conducted using the conventional cultivation system. Results indicated that the optimum application rate of the BSF residue was 10% for enhancing growth. Application of seed density at 30 mg/dm2 produced an optimum marketable yield of the red amaranth since a higher population density causes plant-plant competition. Thus, creating high size variability within the population or reducing the average size of the harvested plants. Lastly, the leaf area of red amaranth can be accurately estimated using the leaf length x width (LW) as a predictor using the zero-intercept linear regression model.

The era of globalization and accelerated economic growth, as well as various kinds of industrial and technological transformations, are currently causing or triggering very concrete environmental problems, one of which is in terms of the growth in consumption of non-renewable energy, namely oil and natural gas. Oil and gas reserves are part of the socio-economic problems in Indonesia. It is known that oil and gas reserves are spread throughout almost all aspects of Indonesia. However, the utilization of the potential reserves of oil and natural gas resources in Indonesia is still not fully optimized. So that the potential for oil and gas reserves in Indonesia still does not fully have a more significant impact on Indonesia's economic growth. This study examines the influence of oil and gas exploration and exploitation in Indonesia on economic growth in Indonesia. This study used data on Indonesia's GDP and Exploitation and Exploitation of Indonesian Oil and Gas in a time series (1996-2021). In analyzing the data, this study used multiple linear regression. The results showed that the exploration and exploitation of oil and gas have a positive and significant effect on economic growth in Indonesia. It is hoped that this study can serve as an impetus for the government in making regulations and regulations directly related to exploration and exploitation activities both upstream and downstream of oil and gas and as encouragement and motivation for governments directly involved with upstream and downstream oil and gas activities. In addition, to issue policies in the form of continuing to prioritize technological development innovations, especially in the oil and gas sector. It is also hoped that the production results obtained from oil and natural gas exploration and exploitation activities can be more optimal and impact national energy security, state revenues, and Indonesia's economic growth.
