Innervation of the pancreas in development and disease
Authors: Agerskov Rikke Hoegsberg , Nyeng Pia
Published: January 2024

The autonomic nervous system innervates the pancreas by sympathetic, parasympathetic and sensory branches during early organogenesis, starting with neural crest cell invasion and formation of an intrinsic neuronal network. Several studies have demonstrated that signals from pancreatic neural crest cells direct pancreatic endocrinogenesis. Likewise, autonomic neurons have been shown to regulate pancreatic islet formation, and have also been implicated in type I diabetes. Here, we provide an overview of recent progress in mapping pancreatic innervation and understanding the interactions between pancreatic neurons, epithelial morphogenesis and cell differentiation. Finally, we discuss pancreas innervation as a factor in the development of diabetes.
Chemi-Northern: a versatile chemiluminescent northern blot method for analysis and quantitation of RNA molecules
Authors: McKenney Katherine M. , Connacher Robert P. , Dunshee Elise B. , Goldstrohm Aaron C.
Published: January 2024

This report describes a chemiluminescence-based detection method for RNAs on northern blots, designated Chemi-Northern. This approach builds on the simplicity and versatility of northern blotting, while dispensing of the need for expensive and cumbersome radioactivity. RNAs are first separated by denaturing gel electrophoresis, transferred to a nylon membrane, and then hybridized to a biotinylated RNA or DNA antisense probe. Streptavidin conjugated with horseradish peroxidase and enhanced chemiluminescence substrate are then used to detect the probe bound to the target RNA. Our results demonstrate the versatility of this method in detecting natural and engineered RNAs expressed in cells, including messenger and noncoding RNAs. We show that Chemi-Northern detection is sensitive and fast, detecting attomole amounts of RNA in as little as 1 sec, with high signal intensity and low background. The dynamic response displays excellent linearity. Using Chemi-Northern, we measure the reproducible, statistically significant reduction of mRNA levels by human sequence-specific RNA-binding proteins, PUM1 and PUM2. Additionally, we measure the interaction of the poly(A) binding protein, PABPC1, with polyadenylated mRNA. Thus, the Chemi-Northern method provides a versatile, simple, and cost-effective method to enable researchers to analyze expression, processing, binding, and decay of RNAs.

Authors: Kul'chickaya Elena
Published: January 2024

Precarization is one of the most important trends in the modern development of the labor market both in Russia and abroad. At the same time, the relevance of managing organizational and non-organizational stresses, which are facilitated by both numerous external factors and changing working conditions, is increasing. This article provides an analysis of the current state of procarization, as well as the results of studies of the causes of precarization, conducted with the involvement of the leaders of 46 service organizations, and studies of the correlation of labor stress and precarization. The main conclusion of the article is the thesis that in order to solve the problems associated with the development of precarization, an integrated approach and the involvement of multi-level actors are needed: the state, entrepreneurs, managers and workers themselves.
Correction of psychological trauma in combat participants using the art-therapeutic method of intuitive drawing
Authors: Sbitneva Olga
Published: January 2024

Unfavorable emotional states disrupt the optimal course of mental functions, form negative features and personality traits that are inadequate to social requirements. They worsen the effectiveness of actions, weaken physical and mental health. In the case when negative conditions are caused by extreme conditions of activity, the development of means of their prevention and regulation is of particular importance. The most significant is the activation of the trigger mechanism for rethinking important aspects of life and creating a positive emotional state for the formation of such mental states that, due to a special internal restructuring of the personality, will contribute to the most optimal use of all mental capabilities of the individual. The purpose of this study, based on theoretical and empirical study of the problem, as well as practical activities, is to determine the effectiveness of the art therapy method (intuitive drawing) in the system of correction of negative mental states of employees of special units of the Ministry of Internal Affairs who participated in hostilities on the territory of the Donetsk People's Republic. The author adheres to the hypothesis that the method of intuitive drawing is effective in use as a method of correcting negative mental states. Allows you to explore the unconscious processes of personality and can contribute not only to the regulation of negative psycho-emotional states, but also relaxation.
Research of professionally important qualities of managers in the system of internal affairs bodies of the Russian Federation
Authors: Bavzhis Al'bin , Maltseva Tatiana
Published: January 2024

In the modern world, the effectiveness of the entire team and the organization as a whole largely depends on the professionalism, skill, experience, and personal psychological qualities of the leader. Today, the conditions of a rapidly changing world require a person to constantly improve himself, develop his individual qualities, increase his abilities and stress resistance. Leaders in the system of internal affairs bodies of the Russian Federation (hereinafter referred to as ATS) are no exception. The research methodology is presented by V.A. Rozanova “Assessing the effectiveness of a manager,” which allows diagnosing the effectiveness of managers, and A. Mehrabian’s questionnaire “Diagnostics of the resulting achievement motivation,” which made it possible to determine the stable personal dispositions of managers regarding the motivation to strive for success and avoid failure. 100 people who were heads of internal affairs bodies of the Russian Federation (hereinafter referred to as heads of internal affairs bodies) were interviewed. Based on the results of the study, it was revealed that the most effective in their activities are the heads of internal affairs bodies who are motivated to strive to achieve their goals and success in all types of their activities, and to self-improvement. Subjects of this type of work are confident in their abilities, responsible, prone to reasonable risks and adequate in their own claims. Heads of internal affairs bodies with average motivation indicators are not sufficiently stable in the desire to achieve success, are not prone to risk, and those with a pronounced motivation to avoid failures are extremely afraid of failure in their actions, do not value themselves in their own eyes and in the eyes of others, and are psychologically inclined to look for possible failures, afraid of responsibility and risk. The article proves the importance of professionally important qualities of managers in the ATS system.
THE INFLUENCE OF TEMPERAMENT PROPERTIES ON THE TEMPORAL ORIENTATION OF PERSONALITY
Authors: Kutenkova Oksana
Published: January 2024

The article deals with the problems of the relationship between the properties of temperament and the temporal orientation of personality. The purpose of the work is to identify certain temperamental properties that determine the resource attitude to the past, present and future or fixation on a certain time period. In accordance with the set goal, 114 cadets of the St. Petersburg University of the Ministry of Internal Affairs of Russia were examined. The group of respondents who took part in the study consisted of 56 girls and 58 boys, whose ages ranged from 17 to 20 years old. To achieve these goals, we used the following methods: the VT questionnaire (questionnaire of temperament properties, author L.V. Kulikov) and the questionnaire "Subjective assessment of temporal orientation" (author S.V. Duhnovsky). Statistical processing was carried out using the analysis of averages, correlation and multiple regression analysis using the computer program for statistical data processing SPSS27. Statistica. It is revealed that the temporal orientation of the subjects of the study is determined by such temperamental properties as "energy", "emotionality" and "rigidity". The analysis of differences in temperament properties between cadets with fixation on a certain time period and cadets with a resource-based time orientation is carried out. The temperamental characteristics inherent in persons with different temporal orientation are described. The question is raised about the actualization of the formulation of official and educational tasks, taking into account the temperamental and temporal characteristics of the personality. The prospects for further research are to clarify information about the influence of mechanisms for reflecting individual characteristics of the personality psyche in temporality.
El devenir contemporáneo de la identidad etnolingüística andaluza: The contemporary evolution of Andalusian ethnolinguistic identity.
Authors: Porrah Blanko Huan
Published: January 2024

Según apreciamos en nuestra experiencia investigadora y revisión de gran cantidad de materiales etnográficos, la identidad etnolingüística andaluza es una de las más estigmatizadas en el contexto cultural hispánico, puesto que incluso es tomada como ejemplo de este tipo de procesos a nivel internacional más allá de este. Para algunos especialistas, dicha estigmatización, tanto de los y las hablantes como de los/as escribientes de la lengua andaluza, se sitúa en el marco de relaciones de poder característico de la colonización y las dinámicas de aculturación y subestimación de los rasgos culturales y lingüísticos del pueblo subalternizado andaluz, especialmente el andaloparlante. Asimismo, encontramos una suerte de resiliencia lingüística entre los efectos de dichas dinámicas, la cual ha ido gestando, sobre todo en las últimas décadas, un movimiento sociocultural denominado andalófilo, agente de toda una diversidad de producción etnoliteraria, literatura escrita de base oral, musical y visual que, a veces sin pretenderlo, plantea un desafío a la perspectiva etnocéntrica de la ideología del españolismo lingüístico, construyendo una identidad lingüística sin complejos entre amplios sectores de la sociedad andaluza.
Turismo morisco: la reinvención mitológica de la Alpujarra. : De Aben Humeya al vino berberisco.
Authors: del Campo Tejedor Alberto
Published: January 2024

A través del análisis del discurso —escrito y oral— y del trabajo etnográfico, se analizan los orígenes y desarrollo de la construcción mitológica de una Alpujarra árabe, y particularmente morisca, hasta su recreación en los últimos decenios en el turismo rural y cultural. Poetas, cronistas, viajeros y otros inventores de la imagen mitificada de esta comarca desde el siglo XVI tienen su continuidad en los planes de desarrollo turístico y las diversas iniciativas que contribuyen a la sucesiva reinvención de la Alpujarra. Como si se tratara de un lugar aislado y encapsulado en el tiempo, la Alpujarra se ofrece al turista como una experiencia en la que revivir la historia de los últimos moriscos y aun el rastro del legado andalusí en Andalucía. Mientras el turismo saca provecho, con el decidido apoyo de las instituciones, del relato maurófilo y romántico, pervive en la Alpujarra el estigma maurófobo que también impregna la imagen del alpujarreño y se actualiza, especialmente, en relación al emigrante magrebí del Poniente almeriense.
Nowa twarz białoruskiej demokracji
Authors: Klimovich Viktoryia
Published: January 2024

The life of the current leader of the Belarusian opposition, Sviatlana Tsikhanouskaya, was turned upside down dramatically when her husband, popular vlogger and opposition leader Sergei Tsikhanouski, was arrested in May 2020 for criticising the government. In response to her husband’s arrest and disqualification as a presidential candidate, Tsikhanouskaya took the brave decision to step into the political spotlight and run as a candidate in the 2020 presidential election in Belarus. Although she had no previous political experience, her campaign gained significant traction and she emerged as the leading opposition figure in favour of democratic reforms, human rights and an end to the authoritarian rule of President Alexander Lukashenko. In August 2020, Sviatlana Tsikhanouskaya was forced to leave the country, though she continues her active and human rights activities abroad. She has been actively engaged in international diplomacy, meeting with world leaders, heads of international organisations, and human rights activists to raise awareness about the situation in Belarus and seek support for the pro-democracy movement. She has called for international pressure on the Lukashenko regime, including sanctions and accountability for human rights violations. The article is dedicated to Sviatlana Tsikhanouskaya and her activities aimed at building a democratic and independent country. A detailed analysis is based on Internet materials, as well as various interviews with the leader of the Belarusian opposition.
Matki kontra feministki: działaczki Zielonych wobec emancypacji kobiet w RFN. Wokół sporu o Das Müttermanifest (1987)
Authors: Trajman Joanna
Published: January 2024

The Green Party, founded in the Federal Republic of Germany in 1980, originated from, among others, the women’s movement. This is why feminist demands such as ending male domination in all aspects of life, breaking traditional gender roles or considering women’s self-advocacy as a central matter, were important elements of the party’s political activity. However, not all of the female members of the party shared such views. Some of them believed that both the women’s movement and political parties, including the Green Party, marginalised women who had children, preventing them from representing their own interests. This led to numerous disputes. These culminated in the controversies surrounding the 1987 publication The Mothers’ Manifesto which referred to the concept of ‘new motherhood’ and the 1970s campaign ‘Wages for Housework’. This article analyses the content of this document and shows the division between its female signatories and the Green Party’s feminists. Furthermore, it presents the response the manifesto evoked from the female activists of the Party and Rita Süssmuth, the Christian Democratic Union Minister of Family Affairs, Senior Citizens, Women and Youth (1986–1988), and the consequences of the publication for women’s policy led by the Greens.
Continuity of Care Increases Physician Productivity in Primary Care
Authors: Kajaria-Montag Harshita , Freeman Michael , Scholtes Stefan
Published: January 2024

Continuity of care, defined as an ongoing therapeutic relationship between a patient and a physician, is a defining characteristic of primary care. However, arranging a consultation with one’s regular doctor is increasingly difficult as practices face physician shortages. We study the effect of declining care continuity on the productivity of physicians by analyzing data of over 10 million consultations in 381 English primary care practices over a period of 11 years. Specifically, we examine whether a consultation with the patient’s regular doctor is more productive than with another doctor in the practice. Using statistical models that account for confounding and selection bias and restricting the sample to consultations with patients who had at least three consultations over the past two years, we find that the time to a patient’s next visit is on average 18.1% (95% confidence interval: 16.9%, 19.2%) longer when the patient sees the doctor they have seen most frequently over the past two years, while there is no operationally meaningful difference in consultation duration. The data show that the productivity benefit of care continuity is larger for older patients, patients with multiple chronic conditions, and patients with mental health conditions. We estimate that the total consultation demand in our sample could have fallen by up to 5.2% had all practices offered continuity of care at the level of the top decile of practices while prioritizing patients expected to yield the largest productivity benefits. We discuss operational and strategic implications of these findings for primary care practices and for third-party payers.

The beverage and food sectors in both Dubai and New York exhibit a wide range of offerings and play a significant role in bolstering their respective economic landscapes. This study examines the durability of food and beverage establishments in Dubai and New York. Utilising a design based on qualitative data has been selected as the chosen methodology for the investigation. Furthermore, a decision was made to carry out semi-structured interviews. A total of ten interviews were conducted, with five conducted with restaurant managers in New York and the remaining five led by cafe managers in Dubai. Thematic analysis was chosen for analysing the gathered data in this research study. Research has demonstrated that marketing and branding are crucial in determining food and beverage enterprises' sustainability and financial prosperity. Furthermore, it has been revealed that a strategy utilised by Dubai food and beverage businesses is offering extraordinary dining experiences. Food and beverage enterprises in New York City often stress and emphasise the importance of quality. Meals and beverage establishments in New York and Dubai prioritise offering exceptional quality meals and beverages to attract clients and justify higher pricing. Moreover, employing technology and thoroughly analysing its current path to attain successful businesses is crucial. Theoretical aspects can provide businesses with a comprehensive understanding of a subject, leading to potential benefits such as producing productive outputs and maintaining a competitive position in the market. The present analysis focuses on the food and beverage industry in Dubai and New York, examining the various aspects of these industries, including food and beverage outlets.

Hemichorea in patients with temporal lobe infarcts: Two case reports
Authors: Wang Xu-Dong , Li Xing , Pan Chun-Lian
Published: January 2024

BACKGROUND

Hemichorea and other hyperkinetic movement disorders are uncommon presentations of stroke and are usually secondary to deep infarctions affecting the basal ganglia and thalamus. Therefore, temporal ischemic lesions causing hemichorea are rare. We report the cases of two patients with acute ischemic temporal lobe infarct strokes that presented as hemichorea.

CASE SUMMARY

Patient 1: An 82-year-old woman presented with a 1-mo history of involuntary movement of the left extremity, which was consistent with hemichorea. Her diffusion-weighted imaging (DWI) revealed an acute ischemic stroke that predominantly affected the right temporal cortex, and magnetic resonance angiography of the head showed significant stenosis of the right middle cerebral artery (MCA). Treatment with 2.5 mg of olanzapine per day was initiated. When she was discharged from the hospital, her symptoms appeared to have improved compared with those previously observed. Twenty-seven days after the first admission, she was readmitted due to acute ischemic stroke. Computed tomography perfusion showed marked hypoperfusion in the right MCA territory. An emergency transfemoral cerebral angiogram was performed and showed severe stenosis in the M1 segment of the right MCA. After percutaneous transluminal angioplasty was successfully performed, abnormal movements or other neurologic problems did not occur. Patient 2: A 76-year-old man was admitted to our hospital for a 7-d history of right-upper-sided involuntary movements. DWI showed an acute patchy ischemic stroke in the left temporal lobe without basal ganglia involvement. Subsequent diffusion tensor imaging confirmed fewer white matter fiber tracts on the left side than on the opposite side. Treatment with 2.5 mg of olanzapine per day improved his condition, and he was discharged.

CONCLUSION

When acute hemichorea suddenly appears, temporal cortical ischemic stroke should be considered a possible diagnosis. In addition, hemichorea may be a sign of impending cerebral infarction with MCA stenosis.
Pedicled abdominal flap using deep inferior epigastric artery perforators for forearm reconstruction: A case report
Authors: Jeon Jae Hyung , Kim Kyung Wook , Jeon Hong Bae
Published: January 2024

BACKGROUND

Pedicled abdominal flaps are a widely used surgical technique for forearm reconstruction in patients with soft tissue defects. However, some drawbacks include restricted flap size, partial flap loss, and donor-site morbidity. To address these concerns, we present a case of a pedicled abdominal flap using the deep inferior epigastric artery perforators (DIEP) for forearm reconstruction in a patient with a large soft tissue defect.

CASE SUMMARY

A 46-year-old male patient was admitted to our hospital with forearm injury caused by a pressing machine. A 15 cm × 10 cm soft tissue defect with complete rupture of the ulnar side structures of the forearm was found. One week after orthopedic management of the neurovascular injury and fractures using the first stage of Masquelet technique, the patient was referred to the plastic and reconstructive surgery department for wound coverage. Surgical debridement and negative-pressure wound therapy revealed a 20 cm × 15 cm soft tissue defect. A pedicle abdominal flap with the DIEP was used to cover the defect. Three weeks later, the flap was detached from the abdomen, and the abdominal defect was directly closed. Subsequently, the second stage of Masquelet technique was performed at the fracture site at week 10. Finally, all donor and recipient sites healed without complications, such as flap dehiscence, infection, hematoma, or necrosis. Fracture site osteosynthesis was achieved without complications.

CONCLUSION

Pedicled abdominal flap using the DIEP provides a reliable option for forearm reconstruction in patients with large soft tissue defects.

Technological sovereignty in Germany: techno-industrial policy as a form of economic statecraft?
Authors: Staab Philipp , Pirogan Marc , Piétron Dominik
Published: January 2024

Technological sovereignty has emerged as a prominent topic, with states positioning themselves to ensure security and economic competitiveness. However, German economic policy rarely involved strategic government interventions and industrial policies due to its deep-rooted adherence to ordoliberalism. In response to the influence of foreign big tech companies and growing economic competition from China, the German state is now formulating a strategic techno-industrial policy agenda, advocating interventions for the preservation of sovereignty. This article analyses the proposed agenda using an inductive process-tracing approach (Trampusch and Palier, 2016) and document analysis (Bowen, 2009) of strategy papers, policy documents and selected media reports. Drawing on the concepts of structural power (Strange, 2004 [1988]) and economic statecraft (Weiss and Thurbon, 2021), we argue that Germany’s pursuit of technological sovereignty represents a distinctive form of (geo-)economically motivated statecraft, primarily directed at enhancing commercial competitiveness rather than prioritising security. However, we identify limitations to this approach where the regulatory regime and institutional legacy, both at the national and EU levels, impede strategic government interventions in the economy, thus constraining the pursuit of technological sovereignty.

Menores de edad expuestos a situaciones de violencia de género en su unidad familiar. Intervención desde el Trabajo Social. El caso de la comunidad autónoma de La Rioja.
Authors: García Gallego Marta , Caparrós Civera María Neus
Published: January 2024

La violencia de género ha pasado de ser una realidad oculta a un problema de carácter social y público. Sin embargo, sigue siendo una realidad poco visibilizada y documentada aquella en la que se encuentran los niños y niñas que, sin ser aparentemente objeto de violencia, están igualmente expuestos a las conductas agresivas que se ejercen en su sistema familiar. Se hace necesario, por tanto, poner de manifiesto las situaciones de estos/as menores de edad que han crecido en un ambiente negligente que ha obstaculizado su desarrollo normalizado, con graves repercusiones en sus diferentes áreas vitales. En aras de contribuir a este objetivo, se ha llevado a cabo un estudio exploratorio a partir de la realización y el análisis de entrevistas semiestructuradas a trabajadoras sociales que intervienen con familias afectadas por la violencia de género, teniendo como finalidades indagar las situaciones y consecuencias de la exposición de los menores a la violencia de género, así como exponer el papel de la profesión del Trabajo Social en esta problemática social. Los resultados revelan que existen en España servicios básicos y especializados que abordan los diferentes conflictos que surgen en el seno de una familia, y que el patrón de respuesta de estos niños/as expuestos a violencia de género no es homogéneo, pudiendo adoptar múltiples roles o consecuencias, que deberán tener en cuenta los/las profesionales del Trabajo Social al diseñar la intervención. Este artículo plantea la necesidad imperiosa de mejorar los canales de comunicación/coordinación entre los diferentes agentes sociales que trabajan con infancia maltratada.
English loanwords and the presence of hesitation phenomena in speech of European Spanish an Mexican speakers an approach
Authors: Illésné Weeber Ágnes
Published: January 2024

This article analyses the prosodic adaptation of Anglicisms in a spontaneous speech context by native European Spanish and Mexican speakers. The change of code between languages ​​may carry prosodic markers (Navracsics, 2014), which can be a disfluency phenomenon, such as a short pause or syllable lengthening for hesitation — these being the two most common hesitation patterns (Deme & Markó, 2013). The research has been conducted on filled pauses and lengthening of the Spanish and Mexican language varieties, based on audio corpus of native Spanish and Mexican speakers, following Cantero’s method of  Prosodic Analysis of Speech (2019) with modest changes.
In this preliminary study, we have found that hesitation can be observed in the context of Anglicisms in the majority of both Mexican and Spanish speech productions, but a difference was discovered in its placement within the sentence. Furthermore, according to the sample, the relative syllable lengths of European Spanish speakers on a lengthened syllable differ more from the previous or the average syllable length of the speaker than in the case of slower Mexican speakers, where it is not always an obviously detectable phenomenon. Therefore, the decrease of speech rate around Anglicisms in the case of European Spanish speakers is more noticeable. Although longer syllables were also observed on Anglicisms themselves, the extent of this prolongation differed from the degree of syllables containing the hesitation phenomenon, and was probably caused only by the slower articulation of consonant clusters characteristic of Anglicisms.
Recursos pragmaprosódicos transicionales en los actos de habla directivos en Antioquia, Colombia: una aproximación desde el género
Authors: Muñoz Builes Diana
Published: January 2024

En este estudio se analizan los recursos prosódicos y pragmáticos que utilizan los hombres y mujeres de Antioquia (Colombia) para marcar diferencias dentro de tres actos de habla directivos: órdenes, peticiones de acción corteses y ruegos. La muestra analizada se conformó a partir del habla de 32 participantes, clasificados según el sexo, el grupo etario, el estrato socioeconómico y el área dialectal de pertenencia. Las muestras de habla fueron obtenidas a partir de un instrumento de Discourse completion tasks (Blum-Kulka, 1980). El análisis prosódico se hizo a partir de la medición de parámetros como la declinación, el rango tonal y la velocidad de habla. Los resultados sugieren que los comportamientos prosódicos y usos de recursos pragmáticos difieren de acuerdo con el sexo del hablante. Los hombres enuncian las órdenes de manera más directa y con menos recursos reparadores; los ruegos de manera impositiva y precisa, y las peticiones de acción con prosodia convergente de órdenes. Por su parte, las mujeres realizan las órdenes con más estrategias de reparación, mitigadores, justificaciones; los ruegos con alargamientos vocálicos, amplio rango tonal y una parte propositiva en el enunciado, y las peticiones de acción con patrones prosódicos de los ruegos.
A Window onto the Heart: Cervantes and the Cardiocentric Self
Authors: Domínguez Julia
Published: January 2024

ABSTRACT: Longstanding representations of the heart and all its complexities in art, religion, literature, medicine, and natural philosophy depicted the organ as the center of feelings, but early modern advances in anatomy led to a physiological reinterpretation. Cervantes was aware of both traditions, and the Cervantine heart repeatedly appears subject to surveillance. For Cervantes, to open a window onto the heart of his characters is to reveal an interior ensconcing secrets and passions, offering an intimate view of feelings and images. This is especially relevant in the Cave of Montesinos, where the knight's solitary spelunking marks a pivotal moment, as his physical descent into the cave is commensurate with higher self-revelation, marking the episode as a synecdoche for the larger work. Seen as an act of individual introspection, Don Quixote's experience unveils his confused interior, opening a window to the protagonist's concealed and most deep-seated anxieties that demystifies his decreasingly idealized chivalric world. ABSTRACT: Longstanding representations of the heart and all its concomitant complexities in art, religion, literature, medicine, and natural philosophy depicted the organ as the center of feelings and emotion, but early modern advances in anatomy led to a physiological reinterpretation. Cervantes was aware of both traditions and throughout his oeuvre the Cervantine heart repeatedly appears subject to surveillance, yet open to scrutiny. For Cervantes, to open a window onto the heart of his characters is to reveal a hidden interior ensconcing secrets and passions, offering an intimate view of feelings and images. This is especially relevant in the Cave of Montesinos where the knight's solitary spelunking marks a pivotal moment in the novel as his physical descent into the cave is commensurate with higher self-revelation, marking the episode as a synecdoche for the larger work. Seen as an act of individual introspection and an exploration of his inwardness, Don Quixote's experience unveils his confused and perplexed interior, opening a window to the protagonist's concealed and most deep-seated anxieties that demystifies his less and less idealized chivalric world.
"No fue engaño; fue prudencia": Maternidad y liderazgo político en El rey más perfeto de Antonio Enríquez Gómez
Authors: Saen de Casas Carmen
Published: January 2024

RESUMEN: El rey más perfeto es una de las comedias que Antonio Enríquez Gómez escribió durante la década de 1650 tras regresar del exilio y reinventarse en Sevilla como Fernando de Zárate. Concebida para promover la canonización de Fernando III de Castilla y León, la pieza busca principalmente exaltar la figura del monarca. Sin embargo, Enríquez Gómez también celebra a su madre, la reina Berenguela de Castilla, enfatizando el importante papel político que desempeñó para asegurar y legitimar a Fernando en el trono. Este artículo estudia cómo el dramaturgo reconfigura la imagen histórica de Berenguela para que responda al modelo de reina propuesto en uno de sus tratados políticos, Luis dado de Dios (1645), pero también para participar en el debate que se desarrolla en el siglo XVII en torno al legítimo uso de la simulación y disimulación política vinculándolo al arte de la prudencia y al concepto de razón de Estado.

Sin embargo, Enríquez Gómez también celebra a su madre, la reina Berenguela de Castilla, enfatizando el importante papel político que desempeñó para asegurar y legitimar a Fernando en el trono. Este artículo estudia cómo el dramaturgo reconfigura la imagen histórica de Berenguela para que responda al modelo de reina propuesto en uno de sus tratados políticos, Luis dado de Dios (1645), pero también para participar en debate que se desarrolla en el siglo XVII en torno al legítimo uso de la simulación y disimulación política vinculándolo al arte de la prudencia y al concepto de razón de estado. Abstract: The Perfect King is one of the comedias written by Antonio Enríquez Gómez during the 1650s when he returned from exile and reinvented himself in Seville as Francisco de Zárate. Aiming to promote the canonization of Ferdinand III of Castile and León, the piece is fundamentally an exaltation of the figure of the monarch. Nevertheless, Enríquez Gómez also celebrates his mother, Queen Berenguela of Castile, emphasizing the crucial political role she played in legitimizing and securing Ferdinand's ascension to the throne. This article studies how the playwright reconfigures Berenguela's historical image to illustrate the model of queenship outlined in his political treaty Luis dado de Dios (1645), but also to participate in the seventeenth-century debate around the legitimate use of political simulation and dissimulation in connection with the art of prudence and the concept of reason of state.
Los Tejanos as a Nineteenth-Century Border Play
Authors: Gibb Andrew
Published: January 2024

Abstract: Since the 1980s, playwrights in the Mexican Northwest/US Southwest have responded to the steadily increasing militarization of the US-Mexico border by dramatizing the fraught identity choices forced upon borderlanders by geopolitical forces beyond their control. In the US, the term "border play" is commonly used to describe such works. In this essay, I argue that the border play, as a regional form, has roots far deeper than the late twentieth century. I offer as an example Los Tejanos , a nuevomexicano secular drama dated to the 1840s, which tells the story of an invasion of the then Mexican department of New Mexico by the neigh-boring Republic of Texas. While the play's plot conveys an explicitly patriotic tale of New Mexican solidarity in the face of Anglo aggression, an analysis of its characters reveals that national, ethnic, and racial identities were far less settled at that time than the script suggests. I contend that the categorization of Los Tejanos as a border play reveals the form to be a deeply historical and regionally-specific artistic response to the ambiguous nature of borderland identities. Additionally, the appearance of a prominent Native American character in Los Tejanos speaks to the centrality of indigeneity to regional identity formation in the past, thus drawing attention to the relative lack of Indigenous presence in recent US border plays.
Archivo y repertorio en el docudrama transfronterizo (Ciudad Juárez-El Paso): La sal de la guerra de Selfa Chew
Authors: Montiel Carlos Urani
Published: January 2024

Abstract: The theatre of Selfa Chew (Mexico City, 1962) takes ownership of historical events to add fictional but feasible possibilities within the represented political reality to which it belongs as a descendant or heir. The docudrama The Salt of War is an example of such theatre. The possible scenarios of this dramatic text, written in 2014, are constructed with the same subjectivity as the official U.S. versions of the exploitation of natural resources after the demarcation of the Mexico-U.S. border in 1848, the Apache extermination (1861-1886), and the conflict over the exploitation of salt between the residents of the town of San Elizario and the Texan authorities (1877). For the analysis, I focus on the main components of the text: 1) Documentary: the actual reference; 2) Archive/repertoire: the deficit of documentary sources and the use of the collective memory of the people involved; 3) Female characters: the relevance of the way in which women are portrayed; and 4) Cross-border region: the geographic coordinates where the factors that afflict its inhabitants take place: marginalization, racism, xenophobia; and other issues that, in a timeless way, persist in this liminal zone, facilitating the connection of the plays with their ideal audience.
Substrip-based registration and automatic montaging of adaptive optics retinal images

Precise registration and montage are critical for high-resolution adaptive optics retinal image analysis but are challenged by rapid eye movement. We present a substrip-based method to improve image registration and facilitate the automatic montaging of adaptive optics scanning laser ophthalmoscopy (AOSLO). The program first batches the consecutive images into groups based on a translation threshold and selects an image with minimal distortion within each group as the reference. Within each group, the software divides each image into multiple strips and calculates the Normalized Cross-Correlation with the reference frame using two substrips at both ends of the whole strip to estimate the strip translation, producing a registered image. Then, the software aligns the registered images of all groups also using a substrip based registration, thereby generating a montage with cell-for-cell precision in the overlapping areas of adjacent frames. The algorithm was evaluated with AOSLO images acquired in human subjects with normal macular health and patients with age-related macular degeneration (AMD). Images with a motion amplitude of up to 448 pixels in the fast scanner direction over a frame of 512 × 512 pixels can be precisely registered. Automatic montage spanning up to 22.6 degrees on the retina was achieved on a cell-to-cell precision with a low misplacement rate of 0.07% (11/16,501 frames) in normal eyes and 0.51% (149/29,051 frames) in eyes with AMD. Substrip based registration significantly improved AOSLO registration accuracy.
Improved resolution in fiber bundle inline holographic microscopy using multiple illumination sources
Authors: Hughes Michael R. , McCall Callum
Published: January 2024

Recent work has shown that high-quality inline holographic microscopy images can be captured through fiber imaging bundles. Speckle patterns arising from modal interference within the bundle cores can be minimized by use of a partially-coherent optical source such as an LED delivered via a multimode fiber. This allows numerical refocusing of holograms from samples at working distances of up to approximately 1 mm from the fiber bundle before the finite coherence begins to degrade the lateral resolution. However, at short working distances the lateral resolution is limited not by coherence, but by sampling effects due to core-to-core spacing in the bundle. In this article we demonstrate that multiple shifted holograms can be combined to improve the resolution by a factor of two. The shifted holograms can be rapidly acquired by sequentially firing LEDs, which are each coupled to their own, mutually offset, illumination fiber. Following a one-time calibration, resolution-enhanced images are created in real-time at an equivalent net frame rate of up to 7.5 Hz. The resolution improvement is demonstrated quantitatively using a resolution target and qualitatively using mounted biological slides. At longer working distances, beyond 0.6 mm, the improvement is reduced as resolution becomes limited by the source spatial and temporal coherence.
Bringing metasurfaces to analytical lens design: stigmatism and specific ray mapping
Authors: Borne Jeck , Bouillon Christopher , Piché Michel , Thibault Simon
Published: January 2024

We propose a method to design the exact phase profile of at least one metasurface in a stigmatic singlet that can be made to implement a desired ray mapping. Following the generalized vector law of refraction and Fermat’s principle, we can obtain exact solutions for the required lens shape and phase profile of a phase gradient metasurface to respect particular ray conditions (e.g., Abbe sine) as if it were a freeform refractive element. To do so, the method requires solving an implicit ordinary differential equation. We present comparisons with Zemax simulations of illustrative designed lenses to confirm the anticipated optical behaviour.
Dissipative coupling in a Bragg-grating-coupled single resonator with Fano resonance for anti-PT-symmetric gyroscopes

Anti-parity-time-symmetric Hamiltonians show an enhanced sensitivity to external perturbations that can be used for high-performance angular velocity sensing. Dissipative coupling is a valuable way for realizing anti-PT-symmetric Hamiltonians with optical resonators and is usually obtained by means of auxiliary waveguides. Here, we model and experimentally show the dissipative coupling between two counterpropagating modes of a single resonator, by means of a Bragg-grating placed in the feeding bus. The proposed solution enables the possibility of accurately designing the dissipative coupling strength in integrated non-Hermitian gyroscopes, thus providing high flexibility in the design of the proposed sensor. Moreover, we theoretically and experimentally demonstrate that the dissipative coupling between two counterpropagating modes of the same resonant cavity can give rise to an asymmetric Fano resonance.
Large viewing angle integral imaging 3D display system based on a symmetrical compound lens array

We propose a large viewing angle integral imaging 3D display system based on a symmetrical compound lens array (SCLA). The display system comprises a high-resolution 2D display panel, an SCLA, and a light shaping diffuser. The high-resolution 2D display panel presents an elemental image array, the SCLA modulates the light rays emitted from the 2D display panel to form 3D images in space, and the light shaping diffuser eliminates the gaps between 3D pixels of the 3D images. We find that the lateral aberration is a crucial factor that affects the resolution of the reconstructed 3D image. The symmetrical structure of the SCLA enables a reduced focal length and the elimination of lateral aberration, improving the viewing angle and the 3D image resolution simultaneously. The experimental results confirm that the proposed display system increases the viewing angle to 68.6°, achieving a comparable resolution of the full field of view while maintaining a simple structure.
