A Global Geographic Grid System for Visualizing Bathymetry
Authors: Ware Colin , Mayer Larry , Johnson Paul , Jakobsson Martin , Ferrini Vicki
Published: March 2020

Abstract. A Global Geographic Grid System (Global GGS) is here introduced to support the display of gridded bathymetric data at whatever resolution is available in a visually seamless manner. The Global GGS combines a quad-tree metagrid hierarchy with a system of compatible data grids. Metagrid nodes define the boundaries of data grids. Data grids are regular grids of depth values, coarse grids are used to represent sparse data and finer grids are used to represent high resolution data. Both metagrids and data grids are defined in geographic coordinates to allow broad compatibility with the widest range of geospatial software packages. An important goal of the Global GGS is to support the meshing of adjacent tiles with different resolutions so as to create a seamless surface. This is accomplished by ensuring that abutting data grids either match exactly with respect to their grid-cell size or only differ by powers of two. The oversampling of geographic data grids, which occurs towards the poles due to the convergence of meridians, is addressed by reducing the number of columns (longitude sampling) by powers of two at appropriate lines of latitude. In addition to the specification of the Global GGS. This paper describes a proof-of-concept implementation and some possible variants.

Published: March 2020

Abstract. Cryosphere of the cold-arid trans-Himalayan region is unique with its significant permafrost cover. While the information on the permafrost characteristics and its extent started emerging, the governing energy regimes of this cryosphere region is of particular interest. This paper present the results of Surface Energy Balance (SEB) studies carried out in the upper Ganglass catchment in the Ladakh region of India, which feed directly to the River Indus. The point SEB is estimated using the one-dimensional mode of GEOtop model from 1 September 2015 to 31 August 2017 at 4727 m a.s.l elevation. The model is evaluated using field monitored radiation components, snow depth variations and one-year near-surface ground temperatures and showed good agreement with the respective simulated values. The study site has an air temperature range of −23.7 to 18.1 °C with a mean annual average temperature (MAAT) of −2.5 and ground surface temperature range of −9.8 to 19.1 °C. For the study period, the surface energy balance characteristics of the cold-arid site show that the net radiation was the major component with mean value of 28.9 W m−2 followed by sensible heat flux (13.5 W m−2) and latent heat flux (12.8 W m−2), and the ground heat flux was equal to 0.4 W m−2. The partitioning of energy balance during the study period shows that 47 % of Rn was converted into H, 44 % into LE, 1 % into G and 7 % for melting of seasonal snow. Both the study years experienced distinctly different, low and high snow regime. Key differences due to this snow regime change in surface energy balance characteristics were observed during peak summer (July–August). The latent heat flux was higher (lower) during this period with 39 W m−2 (11 W m−2) during high (low) snow years. The study also shows that the sensible heat flux during the early summer season (May, June) of the high (low) snow was much smaller (higher) −3.4 W m−2 (36.1 W m−2). During the study period, snow cover builds up in the catchment initiated by the last week of December facilitating the ground cooling by almost three months (October to December) of sub-zero temperatures up to −20 °C providing a favourable environment for permafrost. It is observed that the Ladakh region have a very low relative humidity in the range of 43 % as compared to, e.g., ~ 70 % in the Alps facilitating lower incoming longwave radiation and strongly negative net longwave radiation averaging ~ −90 W m−2 compared to −40 W m−2 in the Alps. Hence, the high elevation cold-arid region land surfaces could be overall colder than the locations with more RH such as the Alps. Further, it is apprehended that high incoming shortwave radiation in the region may be facilitating enhanced cooling of wet valley bottom surfaces as a result of stronger evaporation.
Object attraction and the role of structural hierarchy: Evidence from Persian
Authors: Franck Julie , Mirdamadi Farhad , Kahnemuyipour Arsalan
Published: March 2020

Research on subject-verb agreement production in SVO languages has shown that objects moved pre-verbally sometimes trigger attraction, i.e., erroneous agreement of the verb with the object rather than the subject. Moreover, objects c-commanding one of the agreement positions in the hierarchical structure were found to generate stronger attraction than those linearly preceding them. Evidence for the role of c-command comes from the observation that the accusative clitic in French triggers stronger attraction than the preverbal dative pronoun and the PP modifier (Franck et al. 2006; 2010). In this study, we report the results of an experiment in Persian (an SOV language) in which subject–verb agreement was elicited by presenting sentences in Rapid Serial Visual Presentation procedure (RSVP) followed by verb selection (Staub 2009; 2010). We compared attraction errors induced by pre-verbal accusatives versus datives in the canonical SOV word order as well as the OSV word order. Corroborating Franck et al. (2006; 2010), we found stronger attraction when the pre-verbal object occupies a c-commanding position in the hierarchical structure than when it simply precedes one of the agreement positions in the linear string. We also found stronger attraction in the OSV word order as compared to the canonical SOV word order. This finding is attributed to the real-time processes of erroneous structure building and/or erroneous controller selection during subject-verb agreement computation.
On the Mechanisms for Low-Sulfide, High-Platinum Group Element and High-Sulfide, Low-Platinum Group Element Mineralization in the Eastern Gabbro, Coldwell Complex, Canada: Evidence from Textural Associations, S/Se Values, and Platinum Group Element Concentrations of Base Metal Sulfides

Published: March 2020

The Eastern Gabbro, Coldwell Complex, hosts several geochemically and mineralogically distinct Cu-platinum group element (PGE) deposits, including the high-grade W Horizon (>100 ppm Pd-Pt-Au over 2 m). Several magmatic and/or hydrothermal models have previously been proposed to explain the range of enrichment in PGEs observed in the Marathon deposit, but no work has integrated textural and compositional variations in sulfides to elucidate which of these models is most suitable. Additionally, comparatively little work has been done to characterize the genesis of Cu-PGE mineralization that occurs to the northwest of the Marathon deposit in the Eastern Gabbro. Through integration of base metal sulfide (BMS) mineralogy, texture, and trace element chemistry, a wide range of magmatic and postmagmatic processes have been characterized that contributed to the formation of these deposits. In all zones of mineralization in the Eastern Gabbro, chalcophile elements were remobilized from primary chalcopyrite by hydrothermal fluids and precipitated as secondary chalcopyrite, which occurs as a replacement of pyrrhotite and as intergrowths with hydrous silicates. BMSs in the mineralized zones in the Marathon deposit (Footwall zone, Main zone, and W Horizon) experienced higher R factors than those deposits located northwest of the Marathon deposit (Four Dams, Area 41, and Redstone), with BMSs in the W Horizon having experienced the highest R factors. The silicate melts from which the Footwall zone crystallized likely experienced some degree of sulfide segregation at depth, albeit to a much lesser degree than the northern deposits. Additionally, the melts from which the mineralized zones in the Marathon deposit crystallized were likely contaminated by high-S/Se Archean sedimentary rocks, whereas the northern deposits were likely contaminated by low-S/Se igneous and/or metamorphic rocks. BMSs in a chalcopyrite-rich pod located within the vicinity of the Coldwell Complex experienced both high R factors and high degrees of contamination (cf. W Horizon and Footwall zone, respectively). This study illustrates the complexity of processes that generate and modify mineralization in conduit-type Ni-Cu-PGE systems.
Mesozoic Orogenic Gold Mineralization in the Jiaodong Peninsula, China: A Focused Event at 120 ± 2 Ma During Cooling of Pregold Granite Intrusions

Published: March 2020

Jiaodong gold deposits are mainly sited along faulted contacts between Upper Jurassic Linglong granite and Precambrian basement metamorphic rocks or Lower Cretaceous Guojialing granite. Long-standing controversies relate to timing of gold mineralization and granite-gold relationships. In this study, gold-related muscovite consistently provides concordant 40Ar/39Ar plateau ages of 120 ± 2 Ma (2σ) for the Jiaojia, Sizhuang, and Luoshan deposits. Analogous 40Ar/39Ar timing constraints from gold-related muscovite are provided by total gas and high-temperature ages from Fushan, concordant high-temperature ages from Rushan, and fusion-step ages from Xiadian deposits. These new 40Ar/39Ar ages, when combined with previous reliable 40Ar/39Ar and U-Pb age constraints for mineralization, including ages of pre- and postgold dikes, define a widespread gold mineralization event at 120 ± 2 Ma (2σ). Published zircon U-Pb ages for Guojialing and Aishan granite magmatism suggest an ~8-m.y. lag between peak intrusive activity and gold mineralization. This, together with lack of both high-temperature alteration assemblages and alteration and/or metal zonation, indicates that the structurally controlled Jiaodong deposits are orogenic rather than intrusion-related deposits. Despite this, granite intrusions are considered to have provided suitable fluid trap sites. New 40Ar/39Ar analyses of biotite from the Linglong and Guojialing granites show they had cooled to about ~300° ± 50°C by ca. 123 to 124 Ma, providing pressure-temperature conditions similar to those under which most orogenic gold deposits formed close to the ductile-brittle transition. This enabled the effective ingress of fluids at supralithostatic pressures at 120 ± 2 Ma, leading to intensive brecciation, alteration, and deposition of both vein-type and disseminated gold ores. New zircon (U-Th)/He dates together with apatite fission-track data indicate that preservation of the gold province is due to slow postmineralization uplift and exhumation.
“Yes to discuss different models of care between primary care physicians and diabetes-practice nurses, but not to complete implementation yet”: Explorative qualitative study at diabetes clinics in primary health care centres in Muscat, Oman
Authors: Al-Alawi Kamila , Helene Johansson
Published: March 2020

Background: Globally, many models of care through which the way health services are delivered have been adopted within team-based primary health care. Although these models have aimed to solve some of the health care challenges related to physician’s shortages in clinics and further acceptance of non-physician-led clinics, their application is usually determined by a range of factors, such as preparedness of the health care providers, preparedness of patients and support from higher authorities.Objective: The study was designed to explore health care providers’ perceptions for changes in models of care in diabetes clinics at primary health care in Muscat, Oman.Methods: A total of 27 semi-structured interviews were conducted with health care providers involved in diabetes clinics at five purposively selected primary health care centres in Muscat. The interviewees included the core members of the diabetes management team and other supportive members available at the centres, and were of mixed genders, nationalities and professions. Qualitative thematic analysis was applied.Results: The analysis resulted in one main theme, which captured positive responses towards task-sharing model, but revealed worries and requirements for complete implementation. Nurses’ competences and diabetic patients’ acceptance were among the main concerns. Health care providers revealed that for complete implementation of the model, nurses’ involvement in the team could be improved through updating their knowledge and through the provision of support from higher authorities, while diabetic patients’ acceptance could be improved through understanding of their perceived knowledge towards the model which could promote nurse-led clinics.Conclusion: Task-sharing within the discussed possibilities could provide many positive outcomes and a rewarding future for diabetes clinics at primary health care centres. Omani culture could play a role in its implementation; therefore, if successful implementation is desired, carefully considered steps must be applied by the government and the community.

The Relationship Between Possible Self of the Social Studies and History Teacher Candidates and the Attitudes Towards Teaching Profession
Authors: Uygun Kamil , Avaroğulları Muhammet
Published: March 2020

This study was conducted to determine to what extent the attitudes of pre-service teachers of social studies and history towards the teaching profession may predict possible teacher selves. Participants of the research are senior social studies teacher candidates studying at a public university in the spring semester of 2018-2019 academic year and history teacher candidates registered in the pedagogical formation program. Relational survey model, one of the survey models, was used in the research. The data was collected through Teacher Candidates Possible Selves Questionnaire and Attitude Scale towards Teaching Profession. The data obtained from the study were analyzed by Independent samples t test and simple linear regression analysis techniques. According to the results obtained from the research, there was no difference between the attitudes of social studies teacher candidates and history teacher candidates who received pedagogical formation education towards the teaching profession. While the department of teacher candidates was not effective on the expected teacher selves, it was determined that it was effective on the feared teacher selves. It has been understood that the attitude towards teaching profession is effective in predicting expected possible selves, but it is ineffective in predicting feared possible selves that are feared. Suggestions were made in line with the results obtained from the research.

Narrating the Unspeakable
Authors: Harris Shana
Published: March 2020

The use of psychedelic substances has been described as an ‘unspeakable primary experience,’ one that is personal and ultimately indescribable. The ineffable quality of such an experience, however, does not prohibit or invalidate attempts to explain it. The struggle to narrate one’s experience is instead an important endeavor. But, how does narration work if the psychedelic experience is truly unspeakable?  What kind of narratives are possible?  What kinds of narrative work do psychedelics foreclose? This article addresses these questions by analyzing narratives generated about the use of psychedelics for drug treatment.  Drawing on 16 months of ethnographic research at drug treatment centers in Baja California, Mexico, this article examines what narration looks like in the context of a psychedelic-based drug treatment modality. It pays particular attention to how people in treatment retell – or struggle to retell – their experiences with psychedelics to make sense of them and then articulate them for the researcher. I argue that psychedelic experiences pose a unique challenge for the anthropological study of these substances, particularly their therapeutic use.  I show how these experiences resist narrativization in multiple ways, presenting both ethnographic and epistemological obstacles to the production of anthropological knowledge.
Imposter Paranoia in the Age of Intelligent Surveillance
Authors: Kuldova Tereza
Published: March 2020

Artificial intelligence, deep learning and big data analytics are viewed as the technologies of the future, capable of delivering expert intelligence decisions, risk assessments and predictions within milliseconds. In a world of fakes, they promise to deliver ‘hard facts’ and data-driven ‘truth’, but their solutions resurrect ideologies of purity, embrace bogus science reminiscent of the likes of anthropometry, and create a deeply paranoid world where the Other is increasingly perceived either as a threat or as a potential imposter, or both. Social sorting in the age of intelligent surveillance acquires a whole new meaning. This article explores the possible effects of algorithmic governance on society through a critical analysis of the figure of the imposter in the age of intelligent surveillance. It links a critical analysis of new technologies of surveillance, policing and border control, to the extreme ethnographic example of paranoia within outlaw motorcycle clubs – organizations that are heavily targeted by new and old modes of policing and surveillance, while themselves increasingly embracing the very same logic and technologies themselves. With profound consequences. The article shows how in the quest for power, order, profit, and control, we are sacrificing critical reason and risk becoming as a society not unlike the paranoid criminal organizations.
Technological acceptance and media literacy 2005-2018: a longitudinal study of outlooks before, during and post internet adoption
Authors: Dempsey Lauren
Published: March 2020

The growth and acceptance of the internet and associated technology has led to drastic social change regarding day-to-day behaviour. Whilst the uptake of changing technology has been extensively researched, studies tend to focus on the dichotomy between ‘user’ and ‘non-user’ adoption and behaviour. This paper builds on existing knowledge by longitudinally exploring nuances within the ‘user’ grouping, answering two research questions: what discrepancies exist in attitudes shown by those considered as ‘users’, and what implications may these have for obtaining and maintaining media literacy? This study analysed data from the UK communication regulator Ofcom’s Adult Media Lives project; a qualitative study consisting of annual in-home in-depth interviews with the same 18 participants between 2005- 2018. Through a thematic analysis of the raw video footage from each interview, this unique methodology provides a deeper understanding of how the same ‘users’’ outlooks may change over time, exposing how changing attitudes can be a key driver behind the development of media literacy. Four different attitudes were identified: enthusiastic, accepting, resistant and apprehensive. Following positive or negative experiences participants’ outlooks altered over time, shaping their use and often motivating a movement between these fluid attitudinal categories. With these attitudinal shifts their media literacy skills also fluctuated, illustrating how the obtainment of literacy is a volatile, non-linear process, shaped by personal experiences. This study exposes the limitations of only examining a ‘user’/ ‘non-user’ dichotomy, and highlights the importance of considering the nuances between ‘users’ when studying media literacy.
Digitized Educational System

Published: March 2020

Today’s society, economy, and community are involved in terms of information technology usage. Thai university is a national university that has been highly supported by the Thai government. The term “autonomous university” refers to being independently organized under “bureaucratic frameworks.” In other words, being an autonomous university lets the university to re-engineer itself to stay up-to-date for current market demands for labor. Most universities are already autonomous universities, but the system and structures still remain inefficient. Papers are used for records. Thai university has not kept records in soft copies. It is difficult to re-engineer university system because, to implement a new structure, it incurs huge costs. To digitize the university system, technologies, training program, and expertise are required. Moreover, online education and mobile students seem to be far though technology has been fundamentally implemented. Thai university mostly offers traditional classes, which it requires the students to attend with all paper works for the entire period. Active learning that has always been mentioned by government has still not been completely applied. According to these reasons the authors would like to recommend digital instruments, a way to re-engineer university systems, and other factors to support better educational systems.
Opium Alkaloids
Authors: Jafarova Demirkapu Mahluga , Raci Yananli Hasan
Published: March 2020

Opium alkaloids, derived from crude Papaver somniferum L. plant, are potent analgesic drugs, but their use is limited because of dependence and withdrawal. Opium alkaloids activate the mesocorticolimbic dopaminergic system, which project from the ventral tegmental area to the nucleus accumbens and medial prefrontal cortex, and dopamine is critically important in opioid consumption and sustaining. The reward effect resulting from the activation of the dopaminergic system leads to continued opioid consumption and occurs opioid dependence. After the development of opioid dependence, consumption continues to avoid withdrawal syndrome. Opioid dependence is accompanied with tolerance, which requires the use of high doses to achieve the same effect. When tolerance develops, the chronic consumer continues to use opioid above known toxic doses to produce the same effect, which can result in death regardless of the type of opioid used. Raw Papaver somniferum L. has five high-density main opium alkaloids including morphine, noscapine, codeine, thebaine, and papaverine. Some of these alkaloids bind to classical opioid receptors to produce an opioid-like effect, while the other part mediates non-opioid effects. This chapter reviews the opiod history, receptors, mechanism of action, dependence, withdrawal. In addition, general information about five main opium alkaloids, their effects, uses, routes of administration, pharmacokinetics, adverse reactions, contraindications; effects on reproduction, pregnancy, and lactation were compiled.
Human Papillomavirus Awareness, Vaccine Status, and Risk Factors in Female Emergency Patients
Authors: Walter Lauren , Leader Elizabeth , Galbraith James
Published: March 2020

Introduction: A vaccine targeting high-risk human papillomavirus (HPV) strains can effectively prevent HPV-associated cervical cancer risk. However, many girls and women do not receive the vaccine, more often those impacted by health disparities associated with race and/or socioeconomic status. This same disparate population has also been shown to be at higher risk for cervical cancer. Many of these women also rely on the emergency department (ED) as a safety net for their healthcare. This study sought to gather information pertaining to HPV and cervical cancer risk factors, awareness of HPV and the vaccine, as well as HPV vaccine uptake in female patients presenting to an ED.

Methods: We obtained 81 surveys completed by female ED patients. Demographics included age, race, income, insurance status, primary care provider status, and known cervical-cancer risk factors. Subsequent survey questions explored respondents’ knowledge, familiarity, and attitudes regarding HPV, cervical cancer, and the HPV vaccine, including vaccination uptake rates. We analyzed data using descriptive statistics and Fisher’s exact test.

Results: Approximately one in seven respondents (14.8%) had never previously heard of HPV and 32.1% were unaware of the existence of a HPV vaccine. Minority patients, including those who were Black and Hispanic patients, low income patients, and uninsured and publicly insured patients were less likely to be aware of HPV and the vaccine and likewise were less likely to be offered and receive the vaccine. More than 60% of all respondents (61.3%) had never previously been offered the vaccine, and only 24.7% of all respondents had completed the vaccine series.

Conclusion: Female ED patients may represent an at-risk cohort with relatively low HPV awareness and low HPV vaccine uptake. The ED could represent a novel opportunity to access and engage high-risk HPV populations.
Using Tenecteplase for Acute Ischemic Stroke:
What Is the Hold Up?
Authors: Zitek Tony , Ataya Ramsey , Brea Isabel
Published: March 2020

Alteplase is the only Food and Drug Administration-approved intravenous (IV) thrombolytic medication for acute ischemic stroke. However, multiple recent studies comparing tenecteplase and alteplase suggest that tenecteplase is at least as efficacious as alteplase with regards to neurologic improvement. When given at 0.25 milligrams per kilogram (mg/kg), tenecteplase may have less bleeding complications than alteplase as well. This narrative review evaluates the literature and addresses the practical issues with regards to the use of tenecteplase versus alteplase for acute ischemic stroke, and it recommends that physicians consider tenecteplase rather than alteplase for thrombolysis of acute ischemic stroke.

Charles Davenant on the objectives and principles of “political arithmetic” as an instrument of public administration
Authors: Knyazev Pavel
Published: March 2020

In the late XVII century in England has establishes the school of “political arithmetic”, which goal consisted in the analysis of social phenomena on the basis of quantitative indicators. Its main representatives became William Petty, John Graunt and Charles Davenant (1656-1714). The latter left a mark in the history of England as a philosopher, politician and publicist, who made a significant contribution to the development and implementation of the methods of “political arithmetic”. The object of this research is the views of the English thinker, reflected in his pamphlets and treatises of the 1690’s. The subject is the Davenant’s views on the principles and tasks of “political arithmetic” in the context of his political theory. Special attention is given to correlation between Davenant’s views on the development of “political arithmetic’ and his concept of public administration. The scientific novelty lies in the comprehensive examination of the political and economic views of Charles Davenant within the framework of his attitude on the method of “political arithmetic”. The author delivers a thesis on the importance of the political and epistemological context, which formed Davenant’s views on the quantitative indicators. Grasp of quantitative data Davenant correlated directly with the practice of administration. According to the philosopher, a public official having the capacity for “evaluation” and proper interpretation of data could avoid many mistakes in decision-making and reliance on “bad” advices. The thinker suggested that possession of quantitative data and their competent interpretation could increase the efficiency of administration.
Can philosophy be autonomous in the XXI century?
Authors: Gonotskaya Nadezda
Published: March 2020

This article discusses the image of philosophy in modern world in the context of synthesis of the various intellectual and cultural traditions. The author explores the correlation between philosophy and politics, knowledge and power as a certain discursive practice that in an organic part of Western European culture; demonstrates the limits on establishing dialogue between philosophical traditions, schools and strands of thought. Leaning on the ideas of Kant and Foucault in viewing the phenomenon of Enlightenment, the author analyzes the role and place of a philosopher in the political and intellectual environment. The procedure of double sample realized by the philosopher holds the risk of losing its position on the pedestal taken by intellectualism and serve ideology instead, since orientation towards socially-pragmatic actions inevitably requires involvement into a political game. It demands conscious demarcation of the two types of decisions made: on the one hand, it is an existential choice pertinent to the held by philosopher intellectual position; while on the other – a socially-pragmatic, associated with interval choices, not affecting the ultimate grounds of existence. Due to the fact that preservation of the autonomy of philosophical territory in the era of globalization is an acute problem, there is a need for extremely cautious attitude to any attempts of shifting traditions and cultures, which usually assign primary role to the “philosophical reason”.

Spermatozoa of marine invertebrates are attracted to their conspecific female gamete by diffusive molecules, called chemoattractants, released from the egg investments in a process known as chemotaxis. The information from the egg chemoattractant concentration field is decoded into intracellular Ca2+ concentration ([Ca2+]i) changes that regulate the internal motors that shape the flagellum as it beats. By studying sea urchin species-specific differences in sperm chemoattractant-receptor characteristics we show that receptor density constrains the steepness of the chemoattractant concentration gradient detectable by spermatozoa. Through analyzing different chemoattractant gradient forms, we demonstrate for the first time that Strongylocentrotus purpuratus sperm are chemotactic and this response is consistent with frequency entrainment of two coupled physiological oscillators: i) the stimulus function and ii) the [Ca2+]i changes. We demonstrate that the slope of the chemoattractant gradients provides the coupling force between both oscillators, arising as a fundamental requirement for sperm chemotaxis.

La inseguridad es uno de los asuntos de mayor preocupación de la sociedad argentina y uno de los temas más incluidos en las agendas de los medios. El objetivo de este estudio es analizar el tratamiento informativo sobre este tema en contextos electorales y no electorales. Mediante un análisis de contenido sobre tres diarios de importancia nacional, se concluye que las elecciones presidenciales de 2015 no incrementaron la frecuencia de piezas de este tipo, aunque sí se observó un cambio importante en los tópicos cubiertos y los modos de encuadrarlos. Finalmente, las fuentes oficiales predominaron en las coberturas
De pocas a menos manos. La concentración de medios en Costa Rica entre 1990-2017

Published: March 2020

En este artículo analizamos la concentración de la propiedad de los medios en Costa Rica. Para medir la concentración económica, aplicamos el índice Herfindahl-Hirschman a la propiedad de radio y televisión abierta, utilizando datos de los contratos de concesión de frecuencias radioeléctricas (radio y TV), que muestran que la concentración real de los medios es más alta de lo que sugieren los datos de la propiedad formal. Además, mediante un análisis de la evolución histórica contemporánea de la concentración de medios en Costa Rica (1990-2017) demostramos que los niveles de concentración se intensificaron durante las últimas tres décadas
Uso e influencia de Twitter en la comunicación política: el caso del Partido Popular y Podemos en las elecciones generales de 2016

Este trabajo analiza el uso que hicieron de Twitter las cinco cuentas oficiales de las comunidades autónomas con mayor número de seguidores del Partido Popular y Podemos durante la campaña electoral para las elecciones generales de 2016. Siguiendo la metodología del análisis de contenido, se analizaron 1.845 tuits. Los resultados obtenidos confirman el uso de Twitter como herramienta unidireccional, sin llegar a establecerse un diálogo fluido entre partidos y votantes. Twitter es utilizado como un medio para la difusión de información y la promoción de aspectos propios de la campaña electoral.
Charging Quantum Batteries with a General Harmonic Driving Field

Published: March 2020

A general harmonic driving field was considered for improving the charging efficiency of the quantum battery system. Charge saturation was used to describe the charging efficiency, where the charging mode is divided into saturated and unsaturated. The relationships between the time‐dependent charge saturation and parameters of the general driving field were evaluated both analytically and numerically. The Floquet theorem was used to express time‐dependent charge saturation with the quasienergy and Floquet states of the system. The analytical and numerical results were used to identify the best parameter values for optimizing the charging efficiency.
The Effect of the Spin Angular Momentum on the Tight‐Focusing Vortex Hollow Gaussian Beams
Authors: Ye Feng , Zou Jiawei , Deng Dongmei
Published: March 2020

The propagation properties of a hollow Gaussian beam (HGB) carrying on‐axis and off‐axis vortices through a high numerical aperture lens are investigated. The intensity of the focused beam in the focal plane can be controlled by choosing the different topological charges, the beam order, and the semi‐aperture angle. As intrinsic properties, vortex beams possess both spin and orbital angular momenta. The spin angular momenta (SAM) density can be treated as a vector in 3D since it exists in arbitrary orientation during the beam propagation. The vectors of SAM density orientation of the focused beam in 3D rotate around the central axis whose locations mainly rely on the vortices. The magnitude of the SAM density near the focus plane abruptly varies by altering the focal length of the lens. Under tightly focusing condition, two new pairs of vortices generate alternately on x and y axes in the vectorial electric fields, while the topological charges increase by one.
A Nanoboat with Fused Concave N‐Heterotriangulene
Authors: Zhou Leyong , Zhang Gang
Published: March 2020

The surface extension of all‐carbon based bowl‐shaped molecules, such as corannulene and sumanene, to synthesize even larger buckybowls has been widely studied, leaving other concave compounds with heteroatoms less considered. Herein we present a highly curved molecule synthesized via stepwise cyclization of fjords of a bisacridone derivative. Crystallographic analysis unambiguously confirmed a boat‐shaped structure with deformed bottom benzene ring. Theoretical calculation unravels an inversion process with an S‐shaped transition structure rather than a planar one. The enlarged boat demonstrates interesting properties, such as red shifts in absorption and emission spectra, enhanced emission intensity, and convergent frontier molecular orbital energy levels, in comparison to the related concave N‐heterotriangulene.
