Published: June 2023

Understanding the (dis)assembly mechanisms of large metallosupramolecules is critical in their design, stability and diverse applications. Yet this task is difficult because of the inherent complexity of the structures, with many potential pathways of combining (or separating) the constituent building blocks. Here, we use collision-induced dissociation mass spectrometry to study the disassembly of heterometallic complexes, which have attracted interest due to their potential properties as new materials. Collisional activation leads to the formation of a series of previously unknown smaller ring products and we characterise their geometry using ion mobility. Specifically, the disassembly of both {CrxCu2} hourglass structures (x = 10, 12) and of a {Cr12Gd4} cluster shows the formation of rare closed, heptametallic species namely {Cr6Cu}, {Cr5Cu2} and {Cr5Gd2} as dominant products, as well as other closed ions like {Cr5Cu}, {Cr10Cu}, {Cr12Cu}, {Cr10}, {Cr12}, and {Cr6Gd2}. The collision cross section of cyclic products and precursors has a linear correlation with ion mass, a relationship that does not hold for acyclic systems. Thus, ion mobility mass spectrometry can determine whether a candidate polymetallic complex exists as a closed or open structure. As these rings are non-trivial to synthesize individually in solution, we propose the presented workflow as a means to identify and characterise feasible target molecules.

Published: June 2023

Molecular materials are poised to play a significant role in the development future opto-electronic and quantum technologies. A crucial aspect of these areas is the role of spin-phonon coupling and how it facilitates energy-transfer processes such as intersystem crossing, quantum decoherence, and magnetic relaxation. Thus, it is of significant interest to be able to accurately calculate molecular spin-phonon coupling and spin dynamics in the condensed phase. Here we examine the various approximations inherent in spin-phonon coupling and spin dynamics calculations on molecular solids by performing a case study on a single-molecule magnet. Three key results are: i) finite crystalline slab calculations should be avoided; ii) the phonon spectrum in reciprocal space should be sampled as densely as possible; and iii) phonon linewidths, as calculated by periodic density-functional theory, are likely overestimated at low temperature, but are not essential to obtain accurate magnetic relaxation rates provided point ii is adhered to. Calculations using this approach are facilitated by the open-source packages we have developed, which enable cost-effective and accurate spin-phonon coupling calculations on molecular solids with quantitative accuracy.
Iridium-Catalyzed Regio- and Enantioselective Propargylic C−H Silylation
Authors: Zhu Jin , Chang Hai , Wang Yiming
Published: June 2023

ABSTRACT: We report a highly enantioselective intermolecular silylation of the propargylic C(sp3)−H bonds of alkynes for the formation of propargylic silanes. The optimized protocol afforded enantioenriched α-silylated alkynes in good to high yield with excellent levels of stereocontrol under mild conditions. A variety of silyl triflates, either commercial or in situ-generated, were used as the silylation reagents, and a broad range of simple and functionalized alkynes, including aryl alkyl acetylenes, dialkyl acetylenes, and 1,3-enynes, were successfully employed as substrates. In the case of dialkyl acetylene substrates, silylation took place in a highly regi-oselective manner. Preliminary mechanistic experiments suggest a catalytic cycle in which electrophilic addition of the silyl triflate reagent to the Ir center and subsequent deprotonation of a dicationic Ir–alkyne complex are key steps.
Toward Benchmark-quality Ab Initio Predictions for 3d Transition Metal Electrocatalysts - A Comparison of CCSD(T) and ph-AFQMC
Authors: Neugebauer Hagen , Vuong Hung T. , Weber John L. , Friesner Richard A. , Shee James , Hansen Andreas
Published: June 2023

Generating accurate ab initio ionization energies for transition metal complexes is an important step towards the accurate computational description of their electrocatalytic reactions. Benchmark-quality data is required for testing existing theoretical methods and for developing new ones but is complicated to obtain for many transition metal compounds due to the potential presence of both strong dynamical and static electron correlation. In this regime, it is questionable whether the so-called gold standard, coupled cluster with singles, doubles, and perturbative triples (CCSD(T)), provides the desired level of accuracy -- roughly 1-3 kcal/mol. In this work, we compiled a test set of 28 3d metal-containing molecules relevant to homogeneous electrocatalysis (termed 3dTMV) and computed their vertical ionization energies (ionization potentials) with CCSD(T) and phaseless auxiliary-field quantum Monte Carlo (ph-AFQMC). A substantial effort has been made to converge away the phaseless bias in the ph-AFQMC reference values. We assess a wide variety of multireference diagnostics, and find that spin-symmetry breaking of the CCSD wavefunction and in the PBE0 density functional correlate well with our analysis of multiconfigurational wavefunctions. We propose quantitative criteria based on symmetry breaking to delineate correlation regimes inside of which appropriately-performed CCSD(T) can produce mean absolute deviations from the ph-AFQMC reference values of roughly 2 kcal/mol or less, and outside of which CCSD(T) is expected to fail. We also present a preliminary assessment of DFT functionals on the 3dTMV set.

Published: June 2023

The article analyzes the dreams of teenage youth as a social phenomenon. Іt is emphasized that the relevance of the research is related to the transitivity, the instability of the social position of teenagers as a socio-demographic group, which determines the specifics of their life strategies and projects, which is expressed in their dreams. The theoretical basis of the research are the basic concepts of phenomenological methodology. It is noted that the theoretical basis of the publication is the fundamental concepts of phenomenological methodology. It is emphasized that phenomenological sociology rehabilitates the dream as a subject of sociological research, considering it as one of the finite province of meanings within the life world of the personality, which can be attributed to the worlds of fantasy and imagination. The empirical material of understanding the dreams of teenage youth is analyzed, in particular the results of a quantitative sociological study conducted by the Department of Sociology of V.N. Karazin Kharkiv National University among teenage youth in Kharkiv and Kharkiv region in 2013. The article presents the results of a content analysis of schoolchildren' answers to an open question about what they would want from a goldfish if it agreed to fulfill their three wishes. It is emphasized that the data obtained thanks to this method made it possible to distinguish seven groups of schoolchildren' answers: "Life guidelines", "Life strategies", "Significant resources", "Relationships with others", "Supernatural", "Personal desires", "Combined desires". It is noted that among the life goals of schoolchildren in the first place "health", among life strategies – "education", and among resources – "money". The authors focuses on the group of desires "Supernatural", which most clearly demonstrate the essence of the dream, which, although detached from the reality of life, but expresses the deep existential desires of teenagers. The results of the research are presented, indicating the importance of the role of relatives and close peoples in the life world of teenage youth, which is not only significant but also recognized by them. It is emphasized that the obtained data can be interpreted in different ways, including as an expression of teenagers' life landmarks, their life strategies, life plans and/or ideas about the future, that is, using concepts that are more traditional for sociology. The need for further research in this area is noted.
Features of Formation of Advertising Creativity
Authors: Lysytsia Nadiia , Byelikova Yuliya
Published: June 2023

The article is devoted to the study of the peculiarities of advertising creativity. Creativity as a problem for analysis has always been of interest to sociologists, psychologists, economists. In recent decades, the economy of experience has been popular and has been in demand. The economy of experience involves the active use of emotions, emotional creativity, which is called to form an advertising message that is interesting to consumers. However, despite numerous studies of the problems of creativity by representatives of various sciences, some aspects of its use, for example, in advertising, are still insufficiently studied, which determines the topicality of the work. The aim of the article is to identify the features of formation advertising creativity. Measurements (indicators) of creativity (fluency, flexibility, originality, elaboration, semantic flexibility, figurative flexibility, spontaneous flexibility) and their examples in advertising are considered. Features of emotional creativity are analyzed, which may include the development or modification of standard emotions to better adapt to the needs of the individual / group or the development of new forms of expression of emotions. Examples of Ukrainian advertising practices illustrating the use of tools for formation of creative content according to J. Goldberg are given: unification tool, activation tool, metaphor tool, subtraction tool, extreme consequence tool, absurd alternative tool, inversion tool, extreme effort tool. The criteria of creativity are noted: novelty, efficiency, authenticity, and all three of these criteria work only together. The question of the efficiency of advertising creativity is considered: the most famous formula for the impact of advertising product AIDA provides answers to questions about the functions of creativity in advertising - to attract attention, create an emotional response and as a result interest, create a need, stimulate to action. This focuses on the emotional component, emphasizing that without emotion, the chain of effectiveness of the advertising message will not work. It is noted that at each stage of the impact of advertising, creativity can be both functional and dysfunctional. Functional, ie one that contributes to the ultimate goal of advertising – to sell a product / change the pattern of behavior (for social advertising) creativity may be under certain conditions. The conditions of functional and dysfunctional creativity are indicated. Consideration of the conditions of functionality of the advertising creativity allowed us to highlight its features. These are: relevance of the advertised product; adaptation to consumer needs, namely: conformity with consumer values; heterogeneity: the type of creativity may differ depending on the target audience, the stage of the product life cycle and the advertising message; focus on ethical norms. The line between creativity and insults, discrimination can be sensitive. Emotional perception is a key factor in the communicative efficiency of the advertising message.

Judo is often referred to as an explosive sport, which requires great anaerobic strength and capacity, with a well-developed aerobic system. Attaining a high level of physical fitness, strength, and fatigue tolerance is essential for achieving success in competition. Fatigue leads to decreased muscle strength, prolonged reaction time, reduced agility, neuromuscular coordination, overall body speed, concentration, and agility. The intensity at which this phenomenon occurs is known as the lactate threshold. The primary objective of the planned research was to establish a link between maximal oxygen consumption (VO2max), lactate metabolism, and the situational efficiency of selected young judoists. The sample consisted of 30 cadet and junior judo athletes from the national teams of Serbia (average age of 16.43±0.76 years, body height of 176.94±5.15 cm, and body weight of 69.71±10.64 kg). The research employed precisely standardized protocols and modern equipment to determine anthropometric characteristics, and the values of maximal oxygen consumption, lactate thresholds, and the index of a specific judo fitness test among the selected young judo athletes. Based on the obtained results, there was a moderate negative correlation between VO2max and the index of the special judo fitness test, as well as a low correlation between the first lactate threshold (PLAP) and the second lactate threshold (DLAP) with the index of the special judo fitness test (ISJFT). Additionally, a moderate negative correlation was found between VO2max and anthropometric parameters, while PLAP and DLAP exhibited low correlations with anthropometric parameters. The research results quantitatively illustrate the physiological adaptation of the top young judo athletes to the physical demands encountered during years of specific training. The proposed battery of tests can be utilized to assess the functional status of competitors more accurately and determine the competition profile for elite judo athletes.

Climbing performance is considered multifactorial and is characterized by the interaction of technical, tactical, physical, as well as psychological components. However only few studies have investigated these components in elite climbers. The present study aimed to identify elite athletes’ technical and tactical behavior regarding the following parameters: a) type of climbing handhold, b) type of climbing foothold and c) torso motion through video analysis. The sample consisted of the final competitions of IFSC Climbing World Cup Kranj (2019). In total, 543 actions were recorded through SportScout video-analysis program, taking into account the parameters a) type of climbing handhold, b) type of climbing foothold and c) torso motion. According to the results, and concerning handholds, it was observed that the majority of the participants selected to use Incuts / Mini-jugs, regardless of whether they performed the next movement with the left or the right hand. Concerning the footholds, it was found that participants mostly selected to use Big footholds regardless of whether they performed the next movement with the left or the right leg. Finally, regarding the correlation between Torso motion and Handholds and the correlation between Torso motion and Footholds, it was found that the majority of the climbers selected to perform movements without Torso twisting. Only the techniques of stepping with the right foot had a significant effect on the motion of the torso (Chi-Square=15.53, p<0.05).In conclusion, the selection of smaller and more difficult handholds and big footholds, as well as the climber’s trunk maintenance towards the wall are highly important performance elements in elite climbers.

Para tanto, apresentamos como exemplo a já bastante conhecida governação da internet compreendendo sua história e os arranjos de poder que os atores sociais conformam para que a rede tenha êxito. Como principais achados, apontamos que há uma governação global da mídia marcada principalmente pelo forte poder dos Estados ditos desenvolvidos e das empresas privadas multinacionais. A sociedade civil, embora tenha o papel da resistência, tem muitos desafios nesse cenário para se tornar um ator decisivo nas tomadas de decisão ou mesmo na capacidade de influenciar outros atores.
Reflejos de la identidad indígena andina en el videoclip narrativo de la música andina: caso Otavalo – Ecuador
Authors: Farinango Luis
Published: June 2023

Las producciones audiovisuales de los pueblos indígenas se enfocan en el documental y cine, así las reflexiones y los análisis se concentran en los dos ámbitos. Sin embargo, las producciones audiovisuales en otros formatos como: telenovelas, parodias, entrevistas y videoclips no son del interés de los investigadores. En ese marco, se selecciona al videoclip musical como un formato que creció en la última década y que diferentes grupos en la sociedad aprovechan para contar sus historias y propias representaciones de la realidad. Es el caso de la música andina indígena, que a través de la producción del video musical ven en las plataformas digitales los espacios para alojar y difundir la canción andina, promocionar la banda musical y representar la identidad cultural. Por esa razón, el objetivo de este artículo es analizar la relación de los tres componentes básicos de la estructura narrativa en el videoclip musical de los grupos artísticos indígenas de la ciudad de Otavalo en Ecuador. La metodología para el análisis parte desde un enfoque narrativo y se analizarán los personajes, los acontecimientos, las transformaciones y los ambientes. Las conclusiones aportarán conocer cuáles son las características, fortalezas y debilidades en la estructuración del video musical andino indígena.

Published: June 2023

Background

In 2020, due to the COVID-19 pandemic, the European Centre for Disease Prevention and Control (ECDC) accelerated development of European-level severe acute respiratory infection (SARI) surveillance.

Aim

We aimed to establish SARI surveillance in one Irish hospital as part of a European network E-SARI-NET.

Methods

We used routine emergency department records to identify cases in one adult acute hospital. The SARI case definition was adapted from the ECDC clinical criteria for a possible COVID-19 case. Clinical data were collected using an online questionnaire. Cases were tested for SARS-CoV-2, influenza and respiratory syncytial virus (RSV), including whole genome sequencing (WGS) on SARS-CoV-2 RNA-positive samples and viral characterisation/sequencing on influenza RNA-positive samples. Descriptive analysis was conducted for SARI cases hospitalised between July 2021 and April 2022.

Results

Overall, we identified 437 SARI cases, the incidence ranged from two to 28 cases per week (0.7–9.2/100,000 hospital catchment population). Of 431 cases tested for SARS-CoV-2 RNA, 226 (52%) were positive. Of 349 (80%) cases tested for influenza and RSV RNA, 15 (4.3%) were positive for influenza and eight (2.3%) for RSV. Using WGS, we identified Delta- and Omicron-dominant periods. The resource-intensive nature of manual clinical data collection, specimen management and laboratory supply shortages for influenza and RSV testing were challenging.

Conclusion

We successfully established SARI surveillance as part of E-SARI-NET. Expansion to additional sentinel sites is planned following formal evaluation of the existing system. SARI surveillance requires multidisciplinary collaboration, automated data collection where possible, and dedicated personnel resources, including for specimen management.
A large travel-associated outbreak of iatrogenic botulism in four European countries following intragastric botulinum neurotoxin injections for weight reduction, Türkiye, February to March 2023

Published: June 2023

In March 2023, 34 associated cases of iatrogenic botulism were detected in Germany (30 cases), Switzerland (two cases), Austria (one case), and France (one case). An alert was rapidly disseminated via European Union networks and communication platforms (Food- and Waterborne Diseases and Zoonoses Network, EpiPulse, Early Warning and Response System) and the International Health Regulation mechanism; the outbreak was investigated in a European collaboration. We traced sources of the botulism outbreak to treatment of weight loss in Türkiye, involving intragastric injections of botulinum neurotoxin. Cases were traced using a list of patients who had received this treatment. Laboratory investigations of the first 12 German cases confirmed nine cases. The application of innovative and highly sensitive endopeptidase assays was necessary to detect minute traces of botulinum neurotoxin in patient sera. The botulism notification requirement for physicians was essential to detect this outbreak in Germany. The surveillance case definition of botulism should be revisited and inclusion of cases of iatrogenic botulism should be considered as these cases might lack standard laboratory confirmation yet warrant public health action. Any potential risks associated with the use of botulinum neurotoxins in medical procedures need to be carefully balanced with the expected benefits of the procedure.

El advenimiento de la era nuclear, aunado al desarrollo de diversas tecnologías sobre todo en lo referente a telecomunicaciones, ha producido un incremento generalizado de diversos tipos de radiaciones en nuestro ambiente. Además, el ya conocido decremento de la capa de ozono, provoca cambios tan rápidos en el entorno radiológico que no hay a la fecha suficientes estudios que demuestren concluyentemente el potencial riesgo que estas radiaciones representan para los seres vivos. Las Ciencias Biológicas han llegado a tal grado de especialización, que actualmente existe una rama de la Ecología, la así llamada “Radioecología” que se ocupa del estudio del impacto de la energía provocada por diversos tipos de radiaciones en los ecosistemas. En el presente artículo, presentamos información pertinente con objeto de mostrar una panorámica acerca de la influencia de las radiaciones en los organismos y su ambiente. Basándonos en estudios recopilados de la literatura, e investigaciones llevadas a cabo en nuestro laboratorio, se tratarán de manera general las consecuencias que tiene el incremento de la cantidad de radiación en la biósfera.
Las técnicas isotópicas y sus recientes aplicaciones en las ciencias biológicas
Authors: Gamboa-Delgado Julián
Published: June 2023

Diversas técnicas analíticas han sido utilizadas en todas las disciplinas de la biología para generar un conocimiento más claro sobre algún fenómeno en particular. Un grupo de estas metodologías analíticas migró lentamente desde las ciencias geológicas hacia las ciencias biológicas. Tales metodologías están basadas en la determinación de las firmas isotópicas naturales presentes en diversos tipos de materiales, tanto inorgánicos como orgánicos. La mayoría de los elementos químicos que conforman la materia están presentes como dos o más isótopos. La única diferencia entre un isótopo de un mismo elemento y otro, es el número de neutrones, lo cual le otorga una masa ligeramente diferente a cada isótopo. Los isótopos estables han sido ampliamente utilizados como marcadores nutricionales no-peligrosos para estimar la forma en la cual nutrientes y energía son movilizados en los ecosistemas. De igual forma, las técnicas pueden usarse para determinar las rutas migratorias de varias especies y más recientemente han sido de gran utilidad en estudios nutricionales enfocados a evaluar nuevos ingredientes. La ciencia forense de los alimentos también ha utilizado técnicas isotópicas para detectar productos adulterados o falsos. El presente manuscrito muestra una breve revisión de las aplicaciones de los isótopos estables en diversas disciplinas de la biología, enfatizando aquellas áreas en las cuales existe un incremento importante de generación de conocimiento basado en estas técnicas

El catán (Atractosteus spatula) es el pez dulceacuícola de mayor tamaño en las aguas continentales de la vertiente del Golfo de México. Muchas de sus poblaciones han venido declinando no solo en abundancia, sino en su área de distribución y tamaño individual como consecuencia de la sobreexplotación pesquera, la alteración y desaparición de sus hábitats, su alto nivel trófico (i.e. depredador tope) y gran longevidad. Considerando este contexto, el Grupo Ecofisiología dela Facultad de Ciencias Biológicas, UANL, generó un conjunto de estrategias de investigación para desarrollar su cultivo en cautiverio y disminuir así la presión por la actividad pesquera, lo cual contribuye a la solución de un problema de índole faunístico, por ser una especie nativa cuyas poblaciones tienden a desaparecer; de índole comercial, por tratarse de una pesquería tradicional; y de un gran valor científico, por tratarse de organismos primitivos cuyo origen se remonta al Cretácico y que representan relictos taxonómicos y biogeográficos. Este trabajo recoge la información generada por el grupo de investigación en ecofisiología de la Facultad de Ciencias Biológicas-UANL, durante 20 años de estudios sobre esta especie de catán.

El aprovechamiento de residuos industriales es una demanda prioritaria a nivel nacional e internacional, por cuestiones de sustentabilidad, ya que la enorme producción de los mismos es una consecuencia natural de la actividad humana. Puntualmente, de la etapa de desodorización en el proceso de refinación de aceite vegetal se obtiene un subproducto denominado genéricamente ácidos grasos destilados (AGD´s), el cual, según esta revisión, resulta ser rico en fitoesteroles, tocoferoles y escualeno, que son sustancias bioactivas ya que producen efectos hipocolesterolémicos, antioxidantes y emolientes entre otros; por lo tanto, se les considera útiles en la prevención de enfermedades cardiovasculares y degenerativas. Por lo que este trabajo va encaminada a la revalorización de los subproductos para su aprovechamiento y con ello ofrecer una alternativa ambiental económicamente viable en el control de residuos.
Adaptándose a un medio cambiante:

Published: June 2023

En la actualidad, el cambio climático antropogénico representa el mayor desafío para la humanidad. Existen numerosas líneas de evidencia que muestran los impactos negativos que este fenómeno tiene en los sistemas biológicos, tales como cambios en la abundancia, fisiología, distribución y patrones de migración de numerosas especies de fauna. Sin embargo, los cambios en el comportamiento de las especies han sido ignorados por años. El comportamiento, sin embargo, representa un factor crucial en la adaptación y la supervivencia de los organismos, ya que su modificación posee un significado crítico: una señal de alerta en respuesta a condiciones ambientales. Debido a esto, el estudio del comportamiento representa una herramienta valiosa para predecir y evitar a tiempo declives en las poblaciones de organismos con elevada importancia ecológica y económica. El objetivo general de esta revisión es abrir la puerta a una nueva área conocida como Conducta en la Conservación (Conservation Behavior) en nuestro país. Esta revisión de estudios conductuales realizados presenta casos de estudio, llevados a cabo desde los trópicos hasta el Ártico, de las respuestas en la conducta de diversas especies de fauna ante los cambios ambientales. Ésta, a su vez, refleja la importancia de incorporar estudios de comportamiento en estrategias de conservación para comprender cómo los organismos se enfrentarán a un mundo cambiant

La Reserva de la Biósfera de Mapimí fue de una de las primeras reservas de Latinoamérica. Es un sistema desértico en el que a pesar de las las limitantes hídricas y/o altas temperaturas, se presenta una importante diversidad de vertebrados, siendo las aves y mamíferos los de mayor riqueza. Sin embargo, existen presiones antrópicas que han generado diversos problemas para la conservación de algunas de las especies de la reserva. En este artículo, se exponen los diferentes grupos de vertebrados con algunas de sus especies más emblemáticas, así como los beneficios que proveen al sistema y sus principales amenazas. Así mismo, se exponen algunos de los retos para la conservación de la reserva.
Ajolotes, especies endémicas mexicanas en peligro de extinción
Authors: Romero Amador Leticia
Published: June 2023

De acuerdo con el reporte reciente de la Plataforma Intergubernamental sobre la Biodiversidad y los Servicios Ecosistémicos (IPBES), del millón de especies que se encuentran en peligro de extinción en el planeta, el 40% son anfibios, lo que hace a las salamandras y otras especies el principal grupo de riesgo a nivel mundial. En México casi todas las especies micro-endémicas de ajolotes se encuentran en alguna categoría de riesgo y una de las especies más amenazadas actualmente es Ambystoma mexicanum debido a que su hábitat ha sido altamente dañado por las actividades antropogénicas y su lugar de distribución es muy limitado. Mientras que en el norte de México se distribuyen dos especies de ajolotes (A. velasci y A. rosaceum), ambos considerados bajo protección especial según la NOM-059-SEMARNAT-2010. Gracias a la atención que han llamado sus características de regeneración, las especies de Ambystoma spp. son las más estudiadas a nivel mundial, sólo después del ratón, y la obligación de llevar a cabo su conservación es imprescindible tal como ha sido considerado por las autoridades ambientales nacionales e internacionales. El objetivo de este trabajo es presentar una revisión sobre el estado del conocimiento de las especies de ajolotes que habitan en México con énfasis en las del altiplano mexicano, así como las principales amenazas que enfrentan actualmente. Es preciso señalar que la pérdida de estas especies pudiera resultar en el desequilibrio de los ecosistemas repercutiendo en consecuencia en el ser humano.
