Published: June 2022

Abstract: Nowadays, there are more and more coffee producers competing in Indonesia, one of them is Kopi Redo. In competing for customers, promotion carried out by these producers must be done as effectively as possible to attract potential customers, particularly through Instagram as a social media that is used by many coffee producers to introduce their products. The aim of this research is to ascertain customers’ perception towards promotion carried out by Kopi Redo in their Instagram account. Th researchers chose a range as a statistical tool to determine the cutomers’ overall perception, their perceptions towards each variable based on the concept of 4C (Context, Communication, Collaboration, and Connection), as well as towards indicators of each variable. Questionnaire was distributed to the followers of @redo.coffee, which resulted in feedback gathered from 155 respondents. The results showed that consumers had a positive perception in terms of the overall promotion carried out by Kopi Redo on its Instagram account and they also agreed that each variable and indicators had been impelemented effectively.

Published: June 2022

<p> 5G communication systems enable new functions and major performance improvements but at the cost of tougher energy requirements on mobile devices. One of the effective ways to address this issue along with alleviating the environmental effects associated with the inevitable large increase in energy usage is the energy-neutral systems, which operate with the energy harvested from radio-frequency (RF) transmissions. In this direction, this paper investigates the notion of harvesting the ambient RF signals from an unusual source. Specifically, the performance of an RF energy harvesting scheme for multi-user massive multiple-input multiple-output (MIMO) is investigated in the presence of multiple active jammers. The key idea is to exploit the jamming transmissions as an energy source to be harvested at the legitimate users. To this end, the achievable uplink sum rate expressions are derived in closed-form for two different antenna configurations. Two optimal time-switching schemes are also proposed based on maximum sum rate and user-fairness criteria. Besides, the essential trade-off between the harvested energy and achievable sum rate are quantified in closed-form. Our analysis reveals that the massive MIMO systems can exploit the surrounding RF signals of the jamming attacks for boosting the amount of harvested energy at the served users. Finally, numerical results illustrate the effectiveness of the derived closed-form expressions through simulations. </p>

Published: June 2022

<p>Distributed ledger technology (DLT) provides decentralized and tamper-resistant data storage, replicated among mutually untrusting participants. With the advancement of this technology, different privacy-preserving blockchains have been proposed, such as Corda, Hyperledger Fabric, and Digital Asset's Canton. These distributed ledgers only provide \emph{partial consistency}, which implies that participants can view the same ledger differently. </p>
<p>A \emph{view} represents the states of a blockchain available to a particular stakeholder. The combination of views forms an integrated view that represents a consistent global state shared by all participants. </p>
<p>This paper introduces BUNGEE (Blockchain UNifier view GEnErator), the first DLT view generator, to allow capturing DLT snapshots, constructing views, and performing arbitrary operations on those, such as integrating views. Creating and integrating views allows interesting applications, such as stakeholder-centric snapshots for audits, cross-chain analysis, blockchain migration, and data analytics.</p>

Published: June 2022

Objective: As the coronavirus disease 2019 (COVID-19) pandemic continues, clinical and laboratory predictors of progression to serious and lethal types of the illness are urgently needed. We aimed to investigate how well hematologic, biochemical, and immunologic biomarkers could distinguish between patients with and without severe or fatal COVID-19.
Material and Methods: This retrospective study was performed in the internal medicine departments of two institutions. Data were collected from the hospital database, and the medical files of 280 adult COVID-19 were reviewed. The relationship between hematologic and biochemical parameters which include C-reactive protein (CRP)/albumin, urea/albumin, and lactate dehydrogenase (LDH)/albumin ratios and length of hospitalization, disease severity, and survival were investigated.
Results: Our series consisted of 280 adult COVID-19 patients (147 women, 133 men) with an average age of 58.34 ± 18.64 (range: 19 to 93). Most patients (n=171, 61.1%) had mild-moderate disease, while severe disease was diagnosed in 109 cases (38.9%). A total of 36 patients died due to COVID-19 yielding a mortality rate of 12.9%. The average length of hospitalization was 8.98 ± 5.80 days (range: 1-55 days). We noted that (CRP)/albumin, urea/albumin, and lactate dehydrogenase (LDH)/albumin ratios were significantly associated with severity of disease, mortality, and length of hospitalization.
Conclusion: Several biomarkers have been established that could help with risk stratification models for predicting serious and fatal results of COVID-19 infection. We suggest that clinicians closely track CRP/albumin, urea/albumin, and LDH/albumin ratios in hospitalized patients with respiratory distress as indicators for possible critical illness progression.
No booth, no problem. Formación a distancia en interpretación durante la COVID-19 con Collaborate, Skype y Google Meet
Authors: Nieto García Paola 
Published: June 2022

La COVID-19 ha supuesto un punto de inflexión en la realidad de la docencia universitaria. En España, el 14 de marzo de 2020 todas las enseñanzas regladas pasaron a impartirse en modalidad online (Ministerio de la Presidencia, 2020). Lo que para muchas materias teóricas supuso simplemente un cambio de canal en el trasvase de la información de profesor a alumno y en la comunicación entre ambos, para asignaturas prácticas el problema fue mucho mayor. Sin laboratorios ni clínicas donde poder trabajar (Silió, 2020), los profesores tuvieron que estudiar todas las opciones que las instituciones educativas ponían a su disposición para garantizar la adquisición de contenidos y competencias por parte del alumnado.
La docencia en interpretación simultánea fue una de las disciplinas afectadas por el confinamiento. La necesidad de contar con herramientas que permitieran al profesor escuchar a los alumnos sin que ellos se pudieran escuchar entre sí quedaba fuera de las posibilidades que ofrecían los campus virtuales y, por lo tanto, era necesario buscar soluciones que permitieran impartir esta materia con garantías.
En respuesta a la problemática planteada, se realizó un estudio de las herramientas gratuitas existentes y se decidió combinar el uso de plataformas conocidas en el ámbito universitario, como son Collaborate, Skype y Meet y emplearlas en diferentes asignaturas de interpretación impartidas en la Universidad Complutense de Madrid y en la Universidad Europea de Madrid. Gracias a estas herramientas se han podido crear cabinas virtuales y recrear un entorno formativo que ha servido también para introducir aspectos de la interpretación en remoto.

Published: June 2022

Objective
Breast cancer is a heterogeneous disease group that exhibits quite different biological behaviors and bear many genomic traces. Its dependence on sex hormones also determines its relationship with menopausal status. It is divided into five molecular subtypes according to receptor analysis and Ki67 level with immunohistochemical (IHC) markers. This study aimed to examine the relationship between the menopausal status and these molecular subtypes to help determine our treatment strategies.
Material and Method
The database of 250 patients who were operated on for breast cancer in our Oncology Clinic between 2012 and 2020 was retrospectively analyzed. The patients were grouped by their menopausal status and clinicopathological characteristics. Statistical analysis was made at a 95% confidence interval, and a p-value lower than 0.05 was considered statistically significant.
Results
The patients were divided into 2 groups by their menopausal status as 44.8% (n = 112) as premenopausal and 65.2% (n=138) as postmenopausal. In the statistical analysis performed, the level of Ki67 was high in premenopausal women (p=0.015). Also, tumors seen in premenopausal women were associated with ER negativity (p=0.024) and high histological grade (grade3) (p=0.015). It was found that luminal subtype (luminal A, luminal B) breast cancers were observed more frequently in postmenopausal women and non-luminal subtypes (HER2+, TNBC) were observed more frequently in premenopausal women.
Conclusion
The genomic complexity that will determine personalized treatment strategies soon remains to be clarified. There is still a need for randomized, prospective, multidisciplinary, and population-based studies to help us understand this unknown nature.

Abstract
Two high-cadence surveys aiming for rotation period measurements of asteroids have been conducted in 2019 January and October using the Zwicky Transient Facility. From the surveys, 25 large superfast rotators (SFRs) were discovered and they are all main-belt asteroids (MBAs), except for one Mars crosser. These large SFRs have a diameter ranging from 0.43 to 7.87 km and a rotation period between 0.48 and 1.95 hr. Considering their diameters and fast rotations, they cannot be explained by rubble-pile structure unless using extraordinary high bulk densities. Cohesion, if available, can conserve these large SFRs. The estimated cohesion for these large SFRs could be up to thousands of pascals, much higher than the currently estimated cohesion for asteroids and that generated by the regolith of Moon and Mars. Such high-level cohesion can be produced from fine-grain regolith, like clay. However, the availability of such fine-grain regolith for asteroids is still unknown. Although the possibility of these large SFRs being large monolithic objects cannot be ruled out, this scenario is very unlikely given that the timescale of disruptive impact for MBAs in a similar diameter range is 107–108 yr.

Abstract
We present early-time photometric and spectroscopic observations of the Type Ia supernova (SN Ia) 2021aefx. The early-time u-band light curve shows an excess flux when compared to normal SNe Ia. We suggest that the early excess blue flux may be due to a rapid change in spectral velocity in the first few days post explosion, produced by the emission of the Ca ii H&K feature passing from the u to the B bands on the timescale of a few days. This effect could be dominant for all SNe Ia that have broad absorption features and early-time velocities over 25,000 km s−1. It is likely to be one of the main causes of early excess u-band flux in SNe Ia that have early-time high velocities. This effect may also be dominant in the UV filters, as well as in places where the SN spectral energy distribution is quickly rising to longer wavelengths. The rapid change in velocity can only produce a monotonic change (in flux-space) in the u band. For objects that explode at lower velocities, and have a more structured shape in the early excess emission, there must also be an additional parameter producing the early-time diversity. More early-time observations, in particular early spectra, are required to determine how prominent this effect is within SNe Ia.

Abstract
Soft X-ray emissions from solar wind charge exchange (SWCX) are applied in a recently developed approach to study the magnetosphere using panoramic soft X-ray imaging. This study represents the first attempt to distinguish magnetospheric SWCX emissions observed by XMM-Newton during the impact of an interplanetary coronal mass ejection (ICME) and its driven sheath on Earth. In addition, data from the Advanced Composition Explorer (ACE) were available during this same observational period, which is rare in previous studies. Results showed that SWCX emissions peaked during the ICME at approximately 2.3 times the mean of the observation period, although the solar wind flux decreased to a much lower level. A comparison of spectral results with ion data probed by ACE revealed that high ionization states in the ICME effectively enhanced line emission intensity for heavy ions (e.g., Ne, Mg, and Al). Thus, despite a low proton flux, elevated high-valence ion abundance in the ICME favors magnetospheric soft X-ray observations. Furthermore, the fitted X-ray flux of ion line emissions was consistent with elemental abundance ratios determined in situ by ACE, particularly for C5+, C6+, Ne9+, Mg11+, and Mg12+. This confirms the viability of spectral diagnosis of SWCX emissions as a new method for remotely analyzing high-state ion distributions in solar wind. A time-correlated or two-stage efficiency factor is further suggested to better estimate X-ray intensity during an ICME impact, which was ∼1.7 times higher in the ICME than in the sheath.
Francesco I e Genova: quale strategia?
Authors: Pacini Arturo 
Published: June 2022

Per la monarchia spagnola del secolo XVI è stato posto con forza il problema dell’esistenza o meno di una « grande strategia » a sostegno dei suoi obiettivi di supremazia continentale (Geoffrey Parker). La risposta, sostanzialmente positiva, ha evidenziato l’importanza per gli Asburgo dell’asse Milano-Genova come « grande arteria di comunicazione imperiale » (Federico Chabod) per l’accesso all’Italia settentrionale e il transito verso l’Europa centrale e settentrionale. All’inizio della competizione tra gli Asburgo e i Valois Genova era sottoposta in regime pattizio a Francesco I di Francia, e di nuovo lo fu tra il 1527 e il 1528, ma fu poi attratta e infine saldamente collocata nel sistema spagnolo. La strategia di Francesco I riguardo a Genova, e le sue iniziative politiche e militari negli anni Venti del secolo XVI miranti ad acquisirne il dominio e contrastarne l’inserimento nell’orbita imperiale sono i temi affrontati dal presente saggio.
L’intermittence d’une présence
Authors: Leroy Du Cardonnoy Éric 
Published: June 2022

L’article s’intéresse à la présentation de la politique de François Ier en Italie dans les ouvrages historiographiques des pays de langue allemande au cours du XIXe siècle. L’étude permet de montrer qu’après une ouverture du siècle par une biographie sur le roi de France, le personnage et sa politique, au gré de l’évolution et de l’histoire des pays de langue allemande, tend à disparaître pour être finalement remplacé par son ennemi héréditaire, Charles Quint. La difficulté des pays germaniques à se positionner en Europe face au nationalisme et à la constitution d’États-nations, la forme politique que les états allemands prennent au cours du XIXe siècle dans la course à la réalisation de l’unité, la différence entre l’Empire allemand et l’Autriche-Hongrie, les affrontements confessionnels qui en découlent en partie, font que le roi de France devient à la fois un repoussoir en ce qu’il incarne l’hégémonisme expansionniste français et un symbole d’un roi moderne en ce qu’il est l’un des premiers à avoir su utiliser la corde nationaliste pour réunir autour de lui ses sujets dans une politique à visée européenne, notamment en Italie.
Ripensando la storia della maternità
Authors: D’Amelia Marina 
Published: June 2022

In Italy the 1990’s was one of the most vibrant periods in the reflection on motherhood within the feminist movement. The impact of women’s right to choose if, when and how to be a mother influenced gender relationships and exchanges among the generations. Feminist thought on motherhood took different paths, stressing the symbolic authority of femininity, female genealogies and the importance of the maternal bond as a new paradigm for the organization of a society open to the care of others. The journal Memoria, the first intellectual experiment on women’s and gender history in Italy was one of the networks that shaped The History of Motherhood (1997). The volume explored an under researched theme, and expressed a transition in the political subjectivity of the generation active in the Seventies. The volume was shaped by a political context in which the desire and production of knowledge on motherhood took place. It also preserved the diversity of approaches and perspectives related to the study of maternity with an emphasis on the modern and contemporary periods, offering a synthesis that did not take for granted the linear paths of emancipation and modernity. Among the inevitable lacunae, I must acknowledge a lack of visual sources. Despite an initial academic diffidence, The History of Motherhood has in the long run contributed to the growth of a field of investigation. New questions and new sources have shed light on family and patrimonial strategies, access to welfare, single and working mothers, associations, and rights not only among the élites, but among the less privileged. Recent research on the maternal body, reproduction and birth from antiquity to the new reproductive technologies opens the field to new questions and future investigation, challenging conventional chronologies.
The history of masculinity, beyond plurality
Authors: Rizzo Domenico 
Published: June 2022

The paper first dwells on the successful category of « hegemonic masculinity » developed by sociologist Raewyn Connell, highlighting some of its heuristic pitfalls, such as the difficulty in conceptualizing complexity and internal contradictions of masculinities. A similar limit is highlighted in the approach of historian George Mosse and his followers.
A proposal is then submitted to the readers: the heuristic value of “fragility” as a long lasting multifaceted dispositive in the history of Western masculinities, in contrast to the adoption of the historiographical category of “crisis”, which is almost common sense in contemporary societies.
Corpo e maternità
Authors: Filippini Nadia Maria 
Published: June 2022

Italian and French women historians have been the first in Europe to launch a research project about bodily maternity. This issue was deeply connected with the political thinking and claims of Feminism. It could not be otherwise, as maternity not only crosses women’s personal and social biography but also constitutes the cultural power that determines both the representation of femininity and its control. The symbolic value of this representation is crucial especially in the Catholic world. To take on the issue of the “fertile body”, of its pregnancy and delivery has brought to the dismantling of the disciplinary boundaries among anthropology, legal sociology and the history of medicine; it has created new categories and instruments and challenged the chronology borrowed from history. In this respect, the research on maternity has contributed to renovate both the contents and the methodology of traditional historiography. This paper aims to retrace the research itineraries of the last 20 years, by emphasizing the most innovative issues, the research paths, the European networks and the new questions on the floor.
