Abstract
In this study, a large-size eutectic scintillator of Tb-doped BaCl2/NaCl/KCl was grown using the Czochralski (Cz) and halide vertical Bridgman methods (H-VB). The suitability of these two growth methods for growing the eutectic was compared. Finally, 1 inch diameter eutectic bulks were obtained using the H-VB method. The Tb3+-derived strongest intensity peak at approximately 550 nm was observed by X-ray irradiation. An approximately 3 × 3 mm transparent eutectic wafer was cut and polished from the grown eutectic bulk. An imaging test using α-ray was performed using the grown eutectic, a fiber optic plate, and an electron-multiplying CCD camera. The resolution performance for radiation-imaging applications was evaluated.

Published: November 2021

The article presents data on the content and composition of the essential oil of Mentha longifolia (L.) L. plants growing in natural phytocenoses on the territory of Crimea and Abkhazia. It was found that dry raw materials in two samples from natural phytocenoses of Crimea contain 1.27 and 1.76% of essential oil per wet weight, three samples from phytocenoses of Abkhazia contain less essential oil - 0.68, 0.98 and 1.19 %. About 60 components have been identified. Two new chemotypes were identified for Crimea: carvone-piperitone (mass fraction of carvone is 66.65%, piperitone oxide - 14.37%) and piperitone-sabinene (mass fraction of piperitone oxide - 55.19% and cis-sabinene hydrate - 23.51%), and two for Abkhazia: terpene-caryophyllene (α-terpinyl acetate - 51.48%; β-caryophyllene - 9.26%), piperitone-non-petalactone (piperitone oxide - 46.29%; nepetalactone 4aa, 7a, 7aa - 34.85%). These Mentha longifolia chemotypes are promising for use in the food, chemical, pharmaceutical and perfume industries.
Biconed Graphs, Weighted Forests, and $h$-Vectors of Matroid Complexes
Authors: Cranford Preston , Dochtermann Anton , Haithcock Evan , Marsh Joshua , Oh Suho , Truman Anna 
Published: November 2021

A well-known conjecture of Richard Stanley posits that the $h$-vector of the independence complex of a matroid is a pure ${\mathcal O}$-sequence. The conjecture has been established for various classes but is open for graphic matroids. A biconed graph is a graph with two specified 'coning vertices', such that every vertex of the graph is connected to at least one coning vertex. The class of biconed graphs includes coned graphs, Ferrers graphs, and complete multipartite graphs. We study the $h$-vectors of graphic matroids arising from biconed graphs, providing a combinatorial interpretation of their entries in terms of '$2$-weighted forests' of the underlying graph. This generalizes constructions of Kook and Lee who studied the Möbius coinvariant (the last nonzero entry of the $h$-vector) of graphic matroids of complete bipartite graphs. We show that allowing for partially $2$-weighted forests gives rise to a pure multicomplex whose face count recovers the $h$-vector, establishing Stanley's conjecture for this class of matroids. We also discuss how our constructions relate to a combinatorial strengthening of Stanley's Conjecture (due to Klee and Samper) for this class of matroids.

Published: November 2021

AbstractWe created a 20-item parent-report measure of humor development from 1 to 47 months: the Early Humor Survey (EHS). We developed the EHS with Study 1 (N = 219) using exploratory factor analysis, demonstrating the EHS works with 1- to 47-month-olds with excellent reliability and a strong correlation with age, showing its developmental trajectory. We replicated the EHS with Study 2 (N = 587), revealing a one-factor structure, showing excellent reliability, and replicating a strong correlation with age. Study 3 (N = 84) found the EHS correlated with a humor experiment, however it no longer correlated once age was accounted for, suggesting low convergent validity. Subsamples of parents from Studies 2 and 3 showed excellent inter-observer reliability between both parents, and good longitudinal stability after 6 months. Combining participants from all studies, we found the EHS is reliable across countries (Australia, United Kingdom, United States), parent education levels, and children’s age groups. We charted expected humor development by age (in months), and the expected proportion of children who would appreciate each humor type by age (in months). Finally, we found no demographic differences (e.g., country: Australia, Canada, United Kingdom, United States; parents’ education) in humor when pooling all data. The EHS is a valuable tool that will allow researchers to understand how humor: (1) emerges; and (2) affects other aspects of life, e.g., making friends, coping with stress, and creativity. The EHS is helpful for parents, early years educators, and children’s media, as it systematically charts early humor development.

Published: November 2021

Abstract
As part of our continuing study of light variability in protoplanetary nebulae (PPNe), we present the results from a long-term study of nine southern hemisphere objects. We have monitored their light variations over a nine-year interval from 2010 to 2018. These were supplemented by data from the ASAS-SN and ASAS-3 surveys, leading to combined light curves from 2000 to 2020. Pulsation periods were found in seven of the objects, although the three shortest must be regarded as tentative. The periods range from 24 to 73 days. When compared with the results of previous studies of the light variations in PPNe, we find that they show the same trends of shorter period and smaller light variations with higher temperatures. Luminosities were calculated based on the spectral energy distributions, reddening, and Gaia distances, and these confirm the identification of all but one as post-AGB objects. Three of the stars possess long-period variations of 5–19 yr. These are most likely due to the periodic obscuration of the star by a disk, suggesting the presence of a binary companion and a circumbinary disk.
Dynamical Splitting of Spot-producing Magnetic Rings in a Nonlinear Shallow-water Model

Published: November 2021

Abstract
We explore the fundamental physics of narrow toroidal rings during their nonlinear magnetohydrodynamic evolution at tachocline depths. Using a shallow-water model, we simulate the nonlinear evolution of spot-producing toroidal rings of 6° latitudinal width and a peak field of 15 kG. We find that the rings split; the split time depends on the latitude of each ring. Ring splitting occurs fastest, within a few weeks, at latitudes 20°–25°. Rossby waves work as perturbations to drive the instability of spot-producing toroidal rings; the ring split is caused by the “mixed stress” or cross-correlations of perturbation velocities and magnetic fields, which carry magnetic energy and flux from the ring peak to its shoulders, leading to the ring split. The two split rings migrate away from each other, the high-latitude counterpart slipping poleward faster due to migrating mixed stress and magnetic curvature stress. Broader toroidal bands do not split. Much stronger rings, despite being narrow, do not split due to rigidity from stronger magnetic fields within the ring. Magnetogram analysis indicates the emergence of active regions sometimes at the same longitudes but separated in latitude by 20° or more, which could be evidence of active regions emerging from split rings, which consistently contribute to observed high-latitude excursions of butterfly wings during the ascending, peak, and descending phases of a solar cycle. Observational studies in the future can determine how often new spots are found at higher latitudes than their lower-latitude counterparts and how the combinations influence solar eruptions and space weather events.
Learning from text and animations: a study into the need for cross-representational signaling
Authors: Désiron Juliette C. , Bétrancourt Mireille , de Vries Erica 
Published: November 2021

Les théories de l’apprentissage multimédia postulent que la présence de visualisations statiques ou animées améliore la compréhension de textes, mais seulement si les apprenants intègrent ces multiples sources d’information. Cette étude examinait l’effet du signalement par les couleurs et les labels pour guider la génération des liens inter-représentations (LIR) verbales et picturales. Des élèves de 16 ans d’une école secondaire préprofessionnelle (n =148), ayant de faibles connaissances préalables et habiletés en lecture, étudiaient, sur tablette, un document sur la migration du milan noir, dans un parmi trois formats : multimédia (texte et animations) avec LIR, multimédia sans LIR, texte seul. L’apprentissage était mesuré avec un questionnaire et une tâche de dessin. Les résultats montrent que seule la condition multimédia avec LIR est supérieure au format texte seul. Les documents multimédias texte-animations peuvent soutenir efficacement la compréhension lorsqu’un guidage pour soutenir l’intégration texte-image est fourni.
« I know what you mean »: Investigating the sense of agency in learning an abstract mathematical knowledge using a constructivist method in virtual reality
Authors: Hurault Jean-Christophe , Tedesco Adrien , Brunel Lionel 
Published: November 2021

Cette étude utilise une méthode constructiviste d’apprentissage « Hooks and Shifts », auprès des étudiants. Elle est centrée sur la connaissance mathématique abstraite de moyenne et développée en réalité virtuelle. Elle étudie les associations entre « Shifts », situations d’abstraction, et sens de l’agentivité (SdA), caractéristique des apprenants. Une expérience a mesuré le gain d’apprentissage avec la méthode ainsi que le SdA global. Les résultats montrent un gain d’apprentissage significatif, mais des liens équivoques avec le SdA global. Un fort SdA local aurait pu interférer avec cet apprentissage actif. Nous avons donc reproduit l’expérience, mais par apprentissage passif et contrôlant les « Shifts ». Les résultats confirment un effet du SdA global sur l’apprentissage. Présentant des perspectives pratiques et théoriques, nous discutons également de pédagogie par la réalité virtuelle.

Published: November 2021

CADTH recommends that Tukysa should be reimbursed by public drug plans for the treatment of patients with advanced human epidermal growth factor receptor 2 (HER2)-positive breast cancer that cannot be removed by surgery or is metastatic, including patients with brain metastases, if certain conditions are met.
Tukysa should only be reimbursed if prescribed in combination with trastuzumab-capecitabine and the cost of Tukysa is reduced.
Tukysa should only be covered to treat patients who have been previously treated for HER2-positive breast cancer with trastuzumab, pertuzumab, and trastuzumab emtansine (T-DM1).
The first global 883 GHz cloud ice survey: IceCube Level 1 data calibration, processing and analysis
Authors: Gong Jie , Wu Dong L. , Eriksson Patrick 
Published: November 2021

Abstract. Sub-millimeter (200–1000 GHz) wavelengths contribute a unique capability to fill in the sensitivity gap between operational visible–infrared (VIS–IR) and microwave (MW) remote sensing for atmospheric cloud ice and snow. Being able to penetrate clouds to measure cloud ice mass and microphysical properties in the middle to upper troposphere, a critical spectrum range, is necessary for us to understand the connection between cloud ice and precipitation processes. As the first spaceborne 883 GHz radiometer, the IceCube mission was NASA's latest spaceflight demonstration of commercial sub-millimeter radiometer technology. Successfully launched from the International Space Station, IceCube is essentially a free-running radiometer and collected valuable 15-month measurements of atmosphere and cloud ice. This paper describes the detailed procedures for Level 1 (L1) data calibration, processing and validation. The scientific quality and value of IceCube data are then discussed, including radiative transfer model validation and evaluation, as well as the unique spatial distribution and diurnal cycle of cloud ice that are revealed for the first time on a quasi-global scale at this frequency. IceCube Level 1 dataset is publicly available at Gong and Wu (2021) (https://doi.org/10.25966/3d2p-f515).

Published: November 2021

Abstract. The direction and magnitude of carbon dioxide fluxes between the atmosphere and the sea are regulated by the gradient in the partial pressure of carbon dioxide (pCO2) across the air–sea interface. Typically, observations of pCO2 at the sea surface are carried out by using research vessels and ships of opportunity, which usually do not resolve the diurnal cycle of pCO2 at a given location. This study evaluates the magnitude and driving processes of the diurnal cycle of pCO2 in a coastal region of the Baltic Sea. We present pCO2 data from July 2018 to June 2019 measured in the vicinity of the island of Utö at the outer edge of the Archipelago Sea, and quantify the relevant physical, biological, and chemical processes controlling pCO2. The highest monthly median of diurnal pCO2 variability (31 µatm) was observed in August and predominantly driven by biological processes. Biological fixation and mineralization of carbon led to sinusoidal diurnal pCO2 variations, with a maximum in the morning and a minimum in the afternoon. Compared with the biological carbon transformations, the impacts of air–sea fluxes and temperature changes on pCO2 were small, with their contributions to the monthly medians of diurnal pCO2 variability being up to 12 and 5 µatm, respectively. During upwelling events, short-term pCO2 variability (up to 500 µatm within a day) largely exceeded the usual diurnal cycle. If the net annual air–sea flux of carbon dioxide at our study site and for the sampled period is calculated based on a data subset that consists of only one regular measurement per day, the bias in the net exchange depends on the sampling time and can amount up to ±12 %. This finding highlights the importance of continuous surface pCO2 measurements at fixed locations for the assessment of the short-term variability of the carbonate system and the correct determination of air–sea CO2 fluxes.
Геохимические особенности транслокации элементов в системе «почва-растение» по результатам изучения географических районов виноградарства Крыма

Published: November 2021

По своим почвенно-климатическим условиям Крымский полуостров является уникальной географической зоной для выращивания винограда и производства определенных типов крымских вин, которые по вкусовым качествам заметно отличаются от других известных брендов. Важную роль в формировании вкусовых параметров вин играет содержание макро- и микроэлементов, которые путем транслокации могут накапливаться в виноградном растении, включая ягоды. Научной проблемой исследования является защита винной продукции от фальсификации. Установление связи между геохимическими свойствами почвы и вкусовыми качествами вина помогут выявить критерии идентификации географических районов. Целью данного исследования является обоснование предпосылок формирования специфических вкусовых качеств вин в зависимости от геохимии мест произрастания виноградной лозы. Оценка ампелопедологических условий Крымского полуострова показала, что благоприятным биогеохимическим потенциалом обладают территории Юго-Западного и Предгорного Крыма. В результате исследования впервые были получены критерии, по которым можно идентифицировать географические районы виноградарства Крымского полуострова. Для Восточного Крыма характерно повышенное содержание в почве и золе винограда Ni, а Северо-Западный Крым накапливает больше Fe и Pb. Эти критерии могут выступать индикаторами, которые характерны только для определенного географического района виноградарства Крыма.

Ecos clásicos en las silvas de Quevedo
Authors: Ramajo Caño Antonio 
Published: November 2021

AbstractQuevedo addresses in the silvas, using a flexible metric framework according to the Baroque aesthetic renewal, a great scope of topics following the teachings of Statius and including other classical authors. Through apostrophes, the poet converses with various animate and inanimate beings. He raises his personal voice about the inheritance of the imposing Greco-Latin tradition to express a deep aching intimacy or profound philosophical reflections (in line with the prevailing neo-stoicism) touching also the panegyric vein, so frequent in the European poetry of the time.
La silva “Roma antigua y moderna” como obra poética
Authors: Moreno Castillo Enrique 
Published: November 2021

AbstractThis study aims to analyze the silva by Quevedo “Roma antigua y moderna” as a poetic piece. The poem will be explored verse by verse, paying attention to the brusque thematic shifts and stylistic devices concluding with the claim that the main subject—that is, the comparison between Imperial Rome, its past decadence and its resurgence as a spiritual power by means of the Papacy—is a rhetorical frame within which different secondary subjects appear which have more literary importance than the dominant idea.
Igla kao forma specifične materijalne kulture s kraja bronzanog i početka željeznog doba sjeverne Bosne / Pins as a form of specific material culture from the end of the Late Bronze Age and the beginning of the Iron Age in the northern Bosnia
Authors: Jašarević Aleksandar 
Published: November 2021

During the final stages of the Late Bronze Age the territory of northern Bosnia was characterised by remarkable cultural dynamics, visible primarily in the distribution of metal finds: weapons, tools, jewelry, and functional costume objects. The new type of funeral practice – inhumation – emerged here and was perhaps an important factor in the formation and social stratification of communities living here at the end of the Late Bronze Age and the beginning of the Early Iron Age. The area of northern Bosnia is situated between the Pannonian Basin to the north and the mountainous region of the western Balkans to the south commonly referred to as Dinarides. Thanks to its geographical location, the upper course of the Sava River facilitates direct connections with the Alps, while its lower course leads to the Danube that creates a link with the Black Sea region. To the north, the area is open to the wide peripanon regions of Slavonia and Syrmia. Up the Danube valley, the communication corridor reaches Transdanubia and, along the Tisza River, the central part of the Carpathian Basin. This paper presents a specific form of material culture, a bronze pins with disk-shaped head and short thickening on the neck. A total of six pins are known; two of which have been discovered in hoards (Osredak and Gajina pećina), one in a grave (Ostrožac near Cazin), while the remaining pins are chance finds (Donja Dolina, Prud, and Soukbunar). They all come from a very limited region south of the Sava River and chronologically cover the period from the 10th to the end of the 9 century BC or with Ha B2/3 horizon of Central European periodization.
The pins with a disk-shaped head and short thickening on the neck most likely became part of women’s headgear or complex hairstyles, suggesting the development of special local habits and dress codes intended to promote status and rank. The choice of jewelry and local costume of the females yields information on their origins, affiliations, status, and social and economic role within the community. This paper posits that female costume in nothern Bosnia played the role of an important medium of social communication and interaction, and that it was important for the self-identification of its wearer in identifying their status. Furthermore, women’s mobility played an important role in spreading cultural habits at the end of the Late Bronze Age and in the Early Iron Age in the Western Balkans, with such mobility being evidenced through the distribution of personal items, especially jewellery and ornaments. Reasons for this mobility are related to economic, artisanal, military-political, ritual, and other various practices of the time. A special place in these exchanges was afforded to women, who, through exogamous marriages, became visible in the processes of cultural and social interaction.
