Inversion Test and Sitting-Up Oculomotor Patterns in Patients with Graviceptive Heavy Posterior Cupula – A Case Series
Authors: Vats Ajay Kumar , Kothari Sudhir , Khamesra Renu , Vats Shreya
Published: October 2023

A graviceptive heavy posterior cupula typically results from cupulolithiasis and clinically manifests as short vertigo spells when the head moves in the provocative position. Half-Hallpike test (HHT) in posterior cupulolithiasis (PSC-BPPV-cu) elicits an upbeating ipsitorsional nystagmus (UBITN), which lasts more than a minute as per the consensus criteria developed by the Barany Society. In the last decade, cases with canalolithiasis in the short arm of the posterior semicircular canal (PSC-BPPV-sa), wherein the otoconial debris falls on the utricular side of the posterior cupula on getting up from supine, rendering it heavy (graviceptive), have been reported. Such patients complain of sitting-up vertigo, associated with a constant disequilibrium, and anteroposterior truncal oscillations are recorded by ad hoc posturography in many of these patients. The oculomotor patterns generated in such patients during the HHT may be identical to those resulting from PSC-BPPV-cu. Rarely do the two conditions (PSC-BPPV-cu and PSC-BPPV-sa) coexist. Nine cases of graviceptive heavy cupula were diagnosed at our center over a period of 6 months from September 1, 2022, to March 31, 2023, with their characteristic diagnostic oculomotor patterns, distinguishing features, and management discussed. We propose a grading system for the inversion test during the HHT that reliably distinguishes PSC-BPPV-cu from PSC-BPPV-sa, as well as when the two conditions coexist.

Published: October 2023

To report a patient with concomitant aceruloplasminemia (with a novel mutation) and IgG4-related pachymeningitis and to hypothesize on the possible relation between the two diseases. Clinical, radiological, and laboratory features of a 56-year-old lady with chronic headache, bifacial palsy, and cerebellar signs are described. Pathophysiology of aceruloplasminemia leading to hyperferritinemia and consequent immune activation is elucidated. A coherent explanation of IgG4-related pachymeningitis resulting from aceruloplasminemia and hyperferritinemia is given. The patient has aceruloplasminemia with a novel nonsense mutation. She also suffers from biopsy-proven IgG4 related pachymeningitis as per standard criteria. These two seemingly unrelated illnesses are linked by hyperferritinemia. This case is a fine example of Occam’s razor. Immune dysfunction and autoimmune disorders in aceruloplasminemia need to be explored through further studies to look for causal associations.

Published: October 2023

Introduction:

Atopic dermatitis is an inflammatory skin condition that begins in infancy, characterized by extreme skin dryness, excoriations, and erythema. A completely natural product with plant extracts and vegetable oils was developed to manage eczema and associated conditions in a mixed population including infants.

Materials and Methods:

An open-label, single-arm, single-center study was conducted to evaluate the safety and efficacy of the test product on eczema severity. A total of 58 subjects, including infants, children, and adults aged 0 months to 60 years, diagnosed with mild-to-moderate eczema, were included. The subjects applied a small amount of product on the affected area twice daily for 14 days. Three-Item Severity (TIS) score, Eczema Area and Severity Index (EASI) change, and symptomatic relief were assessed at various time points.

Results:

The TIS score in children significantly reduced from baseline at 24 h (12.22%), day 7 (52.26%), and day 14 (79.74%), (all P <0.0001). Similarly, a statistically significant reduction in EASI was observed in adults at day 7 (13.68%) and day 14 (30.87%) (all P < 0.0001), which continued to offer relief throughout the study duration. Irritation significantly decreased from baseline throughout the study duration to day 14 (75.17%) (P < 0.0001). A significant reduction in other symptoms including dryness, itching, rashes, and edema was also seen from day 7 to day 14 (P < 0.0001).

Conclusion:

The test product was found to be safe and effective in reducing eczema severity and associated conditions in infants and adults. It promotes the development of healthy neonatal skin and hence can be considered as a skin-healing cream for infants.
A Review of Dermal Melanocytosis
Authors: Gautam Manjyot , Shingala Kajomi
Published: October 2023

Dermal melanocytosis is a histological term used to describe a clinical spectrum of cutaneous diseases which present as bluish-gray pigmentation of the skin. The most common forms include the Mongolian spot (MS), nevus of Ota, nevus of Ito, and dermal melanocyte hamartoma sharing similar etiologies and histologic findings but different associations and prognosis. Although these lesions usually resolve by 1 to 2 years of age, widespread aberrant MSs, nevus of Ota, and nevus of Ito can persist into adulthood and can become a great concern for the patients regarding the pigmentation and health risk associated with the same. An extensive literature search was done; all clinical trials, randomized double-blind or single-blind controlled trials, open-label studies, retrospective studies, reviews, case series, and case reports concerned with dermal melanocytosis were screened. The selected articles were retrieved; the final manuscript was prepared, analyzed, and presented in a narrative fashion.
Lambert series of logarithm, the derivative of Deninger’s function

and a mean value theorem for
$\zeta \left (\frac {1}{2}-it\right )\zeta '\left (\frac {1}{2}+it\right )$

Published: October 2023

An explicit transformation for the series
$\sum \limits _{n=1}^{\infty }\displaystyle \frac {\log (n)}{e^{ny}-1}$
, or equivalently,
$\sum \limits _{n=1}^{\infty }d(n)\log (n)e^{-ny}$
for Re
$(y)>0$
, which takes y to
$1/y$
, is obtained for the first time. This series transforms into a series containing the derivative of
$R(z)$
, a function studied by Christopher Deninger while obtaining an analog of the famous Chowla–Selberg formula for real quadratic fields. In the course of obtaining the transformation, new important properties of
$\psi _1(z)$
(the derivative of
$R(z)$
) are needed as is a new representation for the second derivative of the two-variable Mittag-Leffler function
$E_{2, b}(z)$
evaluated at
$b=1$
, all of which may seem quite unexpected at first glance. Our transformation readily gives the complete asymptotic expansion of
$\sum \limits _{n=1}^{\infty }\displaystyle \frac {\log (n)}{e^{ny}-1}$
as
$y\to 0$
which was also not known before. An application of the latter is that it gives the asymptotic expansion of
$ \displaystyle \int _{0}^{\infty }\zeta \left (\frac {1}{2}-it\right )\zeta '\left (\frac {1}{2}+it\right )e^{-\delta t}\, dt$
as
$\delta \to 0$

Bounding nonminimality and a conjecture of Borovik–Cherlin
Authors: Freitag James , Moosa Rahim
Published: October 2023

Motivated by the search for methods to establish strong minimality of certain low order algebraic differential equations, a measure of how far a finite rank stationary type is from being minimal is introduced and studied: The
degree of nonminimality
is the minimum number of realisations of the type required to witness a nonalgebraic forking extension. Conditional on the truth of a conjecture of Borovik and Cherlin on the generic multiple-transitivity of homogeneous spaces definable in the stable theory being considered, it is shown that the nonminimality degree is bounded by the

U

-rank plus 2. The Borovik–Cherlin conjecture itself is verified for algebraic and meromorphic group actions, and a bound of

U

-rank plus 1 is then deduced unconditionally for differentially closed fields and compact complex manifolds. An application is given regarding transcendence of solutions to algebraic differential equations.

Performance analysis of atomic magnetometer and bandwidth‐extended loop antenna in resonant phase‐modulated magnetic field communication system
Authors: Lee Hyun Joon , Oh Jung Hoon , Kim Jang‐Yeol , Cho In‐Kui
Published: October 2023

Telecommunications through an electrically conductive medium require the use of carrier bands with very‐low and ultralow frequencies to establish radiofrequency links in harsh environments. Recent advances in atomic magnetometers operating at very‐low frequencies have facilitated the reception of digitally modulated signals. We demonstrate the transmission and reception of quadrature phase‐shift keying (QPSK) signals using a multi‐resonant loop antenna and atomic magnetometer, respectively. We report the measured error vector magnitude according to the symbol rate for QPSK modulation and analyze the bandwidth of a receiver based on the atomic magnetometer. The multi‐resonant loop antenna noticeably enhances the bandwidth by over 70% compared with a single‐loop antenna. QPSK modulation for a carrier frequency of 20 kHz and symbol rate of 150 symbols per second verifies the feasibility of demodulation, and the measured error vector magnitude and signal‐to‐noise ratio are 7.29% and 30.9 dB, respectively.
Control of the BLDC Motor Using Ant Colony Optimization Algorithm for Tuning PID Parameters
Authors: Poudel Yam Krishna , Bhandari Pratap
Published: October 2023

A key component of industrial applications is the DC motor. Hence, due to their superior features and performance, Brushless DC (BLDC) motors are more suitable for fractional kilowatt motor’s applications. Albeit, for the purpose of controlling the speed of Brushless DC motor easily, it is quite difficult for obtaining the best controlling performance through the use of the conventional approaches of tuning. In order to search the Proportional – Integral - Derivative (PID) tuning parameters optimally for the different controllers taken into consideration, the use of modern bio-inspired metaheuristic technique called Ant Colony Optimization (ACO) algorithm is employed. This paper particularly discusses and presents on the tunning parameters of .  The performance of traditional controller and novel approach is compared, analyzed and presented. Brushless DC motor is buildup in MATLAB and the usage, importance, efficiency and strength of the proposed approach is validated against traditional tunning methods. The obtained result shows better performance of the proposed system with the aid of the proposed controllers for different speed trajectories of the drive when compared with that of the classical Proportional – Integral - Derivative (PID) controllers. Ant Colony Optimization (ACO) seems to be the one of the most effective tuning techniques of Proportional – Integral - Derivative (PID) controllers. This research has significant impact on modern control applications.

Identification of Key Gene Modules and Novel Transcription Factors in Tetralogy of Fallot Using Machine Learning and Network Topological Features
Authors: Charles Sona , Natarajan Jeyakumar
Published: October 2023

Tetralogy of Fallot (TOF) is a combinatorial congenital abnormality comprising of ventricular septal defect (VSD), pulmonary valve stenosis, a misplaced aorta and a thickened right ventricular wall. Biologically relevant module identification from transcriptome data may be considered as a binary classification problem. We utilized publicly accessible mRNA expression data to extract the differentially expressed genes (DEGs) and further weighted gene co-expression network analysis to identify ten modules in TOF. Network topological properties of modular and non-modular genes were considered as features for binary classification. We applied SVM, Random Forest, Decision Trees, KNN and Naïve Bayes algorithm to network features. Random Forest and decision tree algorithms displayed an accuracy of 99.1% and 98% respectively. All the methods, in combination predicted 71 common genes which were used to construct a gene regulatory network. The network was expanded to include 30 miRNAs targeting the genes. Interestingly, 39 out of 71 genes were transcription factors out of which ELN, SOX6 and FOXO3 genes are novel candidates in TOF. The work also provides a sub-module of genes and miRNAs supported by statistical models as prospective candidates to be biomarkers.

Persistent SARS-CoV-2 infection in patients with B-cell deficiency: a case series of successful antiviral treatment of four patients
Authors: Faxén Lisa , Edvinsson Marie
Published: October 2023

Persistent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in immunocompromised patients remains a major medical challenge. Diagnosing the syndrome is difficult as symptoms may mimic other diseases and treatment guidelines are lacking. We describe a case series of four patients with persistent SARS-CoV-2 infection that all had an underlying B-cell deficiency due to rituximab treatment (in one case in combination with epcoritamab). In all four patients, it was initially difficult to recognize the persistent disease, leading to a duration of illness between 45 and 242 days. Two patients were only positive for SARS-CoV-2 by polymerase chain reaction (PCR) in the nasopharynx at the beginning of the disease but were later repeatedly negative. However, when bronchoalveolar lavage was performed, a positive SARS-CoV-2 PCR was revealed from the lower airways in both patients. The difficulties establishing diagnosis contributed to these two patients’ long disease course. The longest disease duration was in the patient treated with rituximab and epcoritamab, who also responded poorly to single standard antiviral treatment. This patient ultimately cleared the infection after administering a combination treatment with remdesivir and nirmatrelvir/ritonavir. After a confirmed diagnosis, the other three patients cleared the infection when they were finally treated with antivirals. Increasing clinicians’ awareness of this condition is important as it might be treatable once diagnosed. Further studies are warranted to define the condition and treatment strategy with greater precision.

Authors: Yahaya James J. , Bwambale Phenehas , Morgan Emmanuel D. , Abraham Zephania S. , Owor Gelardine , Wabinga Henry
Published: October 2023

Objectives: Ameloblastoma, comprising approximately 11% of all odontogenic tumors, is a locally aggressive tumor with a high recurrence rate. This study aimed to assess the immunohistochemical expression of Ki-67 and p53 and their association with clinical and pathological factors among patients with ameloblastoma. Methods: Retrospective follow-up data of patients histologically confirmed with ameloblastoma at Makerere College of Health Sciences in Kampala, Uganda from January 2012 to December 2018 were retrieved. Factors associated with Ki-67 and p53 immunohistochemical expression were determined using one-way one-way analysis of variance. Chi-square and Fisher’s exact statistical tests were used to assess factors associated with recurrence. A two-tailed p < 0.05 was considered statistically significant. Results: A total of 40 patients confirmed histologically with ameloblastoma were included in the analysis. The majority (62.5%) of cases were of the conventional type of ameloblastoma. The expressions of Ki-67 and p53 were 52.5% and 85.0%, respectively. Recurrence was found in 47.5% of patients and it was associated with conventional histological type (p=0.042), segmental resection (p < 0.001), tumor size (p < 0.001), and high p53 expression (p=0.041). Conclusions: Almost half the cases in this study had recurrence. The immunohistochemical expression of p53 was significantly higher than that of Ki-67.

Formulation and demonstrations of three-dimensional background-oriented schlieren using a mirror for near-wall density measurements

Three-dimensional background-oriented schlieren (3D-BOS) is an effective method for reconstructing 3D density fields from optically measured data, but it has limitations in measuring near-wall regions, where most of the light paths are blocked. This paper proposes a new extension, 3D-BOS using Mirror, which uses a wall as a mirror to provide sufficient light paths. In this paper, first, the conventional formulations are modified for the proposed method to handle the mirror reflections of the light paths. Subsequently, the proposed method is validated using artificially generated model data of an ideal axisymmetric distribution. The proposed method can reconstruct the distribution as accurately as the conventional method for all the number of cameras examined. Finally, the proposed method is experimentally demonstrated using a candle plume. The proposed method can capture cylindrical low-density regions near the wall surface.

TrackAER: real-time event-based quantitative flow visualization

We present a novel event-based quantitative flow visualization system, TrackAER, capable of continuously reconstructing, rendering and recording particle tracks in large test volumes without limitations on the measurement duration. Multiple event-based cameras are synchronized and calibrated to produce independent and asynchronous, yet temporally co-registered data streams of flow tracer positions. Subsequently, these data streams are merged into time-resolved three-dimensional particle tracks using photogrammetric techniques. Due to the operating principle of event cameras, the flow scenery is reduced to moving objects only, which effectively compresses the data stream at the camera source. In combination with an efficient data processing pipeline, the measurement system operates in real-time, reconstructing and rendering the investigated flow field without noticeable time lag. The data processing approach follows a “per-event” paradigm and enables the immediate observation and analysis of both, transient and long duration flow features. Specific issues resulting from event-based, frame-free processing are discussed as well as the advantages and limitations of event cameras. Exemplary results are provided to demonstrate the utility of the TrackAER system where Lagrangian particle track information is displayed in a virtual scene together with extracted quantitative information such as local flow velocities.

Published: October 2023

Background: Critical illness-associated cerebral microbleeds and leukoencephalopathy connected to coronavirus disease 2019 (COVID-19) infection are emerging areas of concern in current medical literature.

Methods: We reviewed cases of patients with COVID-19-associated neurological manifestations to study the prevalence and outcome of such conditions.

Case Series Findings: Our review yielded seven distinct patients. Six exhibited cerebral microbleeds, primarily localized in the juxtacortical white matter and the corpus callosum. In contrast, one individual presented with leukoencephalopathy. Tragically, of these patients, five succumbed to their ailments. One was discharged with mild cognitive impairments, while another underwent a tracheostomy and was subsequently moved to a long-term care establishment.

Conclusion: Our findings underscore the significance of neuro-radiological observations in those grappling with severe manifestations of COVID-19, drawing attention to the possible neurological repercussions of the virus.
Representación política y movilización social en la Argentina postneoliberal (2003-2013)
Authors: Mauro Sebastián
Published: October 2023

El artículo aborda la relación entre los ciclos de movilización social y la evolución del vínculo de representación política en la Argentina reciente (2003-2013). Se sostiene que los gobiernos kirchneristas han reconstruido la legitimidad de la política reivindicando la movilización social. Por otra parte, se identifican dos períodos en relación a la estrategia kirchnerista frente a los escenarios de protesta social. Durante el gobierno de Néstor Kirchner se ensayó la incorporación de los actores contenciosos ya existentes y de los emergentes. Durante los gobiernos de Cristina Fernández, se optó por el enfrentamiento discursivo con los actores emergentes y por la movilización social en apoyo de

las políticas oficiales. La reaparición de la figura del pueblo, aunque despojada de las características antiliberales de períodos precedentes, podría ser una de las claves para comprender este nuevo período.

En la elección presidencial de 2005 en Chile, la aprobación del presidente era alta, los índices económicos eran buenos y la candidata de la coalición oficialista ganó la elección. En 1999, pese a la baja aprobación presidencial y crecimiento negativo, el candidato oficialista también ganó. Aquí estudiamos el efecto del contexto económico y la aprobación presidencial en el desempeño electoral de los candidatos oficialistas en elecciones presidenciales en Chile entre 1999 y 2013. ¿Bajo qué condiciones de aprobación del presidente saliente y situación económica del país el voto económico importa más? Utilizando los datos de la encuesta CEP, presentamos modelos probit que muestran que la condición socio-económica de los votantes, su identificación con partidos oficialistas y su aprobación presidencial predicen con mayor fuerza la intención de voto por el candidato oficialista que las variables tradicionalmente asociadas al voto económico.

ASPECTS OF SEEDLING PRODUCTION OF Clathrotropis brunnea Amshoff, A THREATENED LEGUME TREE FROM COLOMBIAN RAINFORESTS
Authors: Daibes Luis Felipe , Prato Andrés Iván , Carvalho Fabricio Eulalio Leita
Published: October 2023

Seedling production is crucial to assist restoration and conservation practices of tropical rainforest species. In the present study, we evaluated seedling production of Clathrotropis brunnea Amshoff, a legume tree native to tropical forests of Colombia. Seedling emergence parameters were assessed regarding two classes of seed mass (small seeds < 6.0 g and large seeds > 6.1 g) and tree levels of seed moisture content (control, 30% and 25%). Initial growth was evaluated in two sizes of plastic bags (small: 10 cm diameter x 25 cm height, with a volume of 1,700 cm3, and large: 15 cm x 35 cm and volume of 3,900 cm3), besides tree growth periods in the nursery (170, 205 and 235 days after sowing – DAS). Large seeds provided higher seedlings and reached a greater emergence percentage (93%) compared to the small ones (79%). On average, seeds reached 73% of emergence in the three moisture levels, including when desiccated from 47% in the control (fresh seeds) to 25%. To optimize seedling production and costs, large seeds can be sown in small bags, growing for a minimum of 205 DAS. The in-field performance of the produced seedlings remains to be tested according to these recommendations.
Identifying and responding to trauma in children, young people and families in a hospital setting
Authors: O’Curry Sara , Young Eliane
Published: October 2023

Children and young people may enter a hospital system for a number of reasons including for a diagnosis of a long term, lifelimiting or life-threatening condition, a change in health status or a hospital admission for medical management of a mental health condition. All of which can be conceived of as potential traumatic stressors. For parents and families the subsequent medical investigations and treatments themselves can be traumatic to witness in a loved-one, often accompanied with a high sense of threat, and a low sense of self-efficacy and control, with outcomes often uncertain. Children, young people and families who come to the hospital come with a full range of histories and experiences, from all walks of life and all kinds of cultural backgrounds, that can impact on their ability to trust healthcare staff or to cope with the feelings evoked in this setting. Similarly, hospital staff come to their chosen careers with a range of experiences that can lead to intense emotional responses, are impacted by repeated exposure to traumatic events, and by vicarious trauma from witnessing the trauma of children, young people and families. As well as working directly with children, young people and families, a key role of the psychologist in the paediatric setting is to help contain this anxiety by helping them and staff make sense of and respond to the challenges they face, through sharing a psychological formulation, collaboration, teaching and contributing to the development of policies and procedures that enable the system to prevent, identify and respond effectively to trauma.
Development of the medical admission pack project: Utilising the expert-by-experience voice to improve experiences of medical admissions in young people with eating disorders
Authors: Morris Chloe , Cliff Poppy
Published: October 2023

Young people with eating disorders can present with physical health risks that require admission to a general hospital ward which can be a negative experience. As part of a service development initiative within the CAMHS Community Eating Disorder Service for Rotherham Doncaster and South Humber NHS Foundation Trust, we co-produced a Medical Admission Pack for Young People. It was designed based on assimilated data from a focus group, an interview and surveys, gathered from young people who had experienced an admission to a general ward, their parents/carers and ward staff. Thematic analysis was conducted to derive the three key themes: uncertainty, negative experiences and having a voice. The themes were used to guide the construction of The Medical Admission Pack, which was co-produced between the service and expert by experience service users, in line with the six principles of trauma-informed care (safety, trust, choice, collaboration, empowerment and cultural consideration). The packs were developed to help reduce the negative experiences during admissions by resolving uncertainty – to promote psychological safety and trust – as well as empowering young people. Anecdotal evidence suggests that the aims of the pack were met, however further evaluation is still needed. A further advancement of this pack was an edition for parents/carers, based on similar principles but suited to the needs of the parent/carer The parent/carer pack is relatively new and requires evaluation to determine the effectiveness.
Living with a constant feeling of dread. Dyadic Developmental practice (DDP) with families who foster or adopt children with developmental trauma experience
Authors: Golding Kim S.
Published: October 2023

In this paper I am joined by an adoptive family to explore the Dyadic Developmental Practice (DDP) model. DDP was originally developed by US clinical psychologist, Dan Hughes as an intervention for children living away from their birth family. This model encompasses therapy, parenting, and practitioner support. The same DDP principles of open and engaged emotional connection, PACE, co-regulation, and co-creation of narrative, guide all DDP interventions. These allow everyone to slow down and seek understanding. This increases safety and reduces the risk of blaming or judging the family. The DDP principles, support the child to feel safe enough to move out of blocked trust, to build relationships, to develop an integrated sense of self and a coherent autobiographical narrative.

DDP is developing from its strong foundation in Western psychological models, including attachment theory, intersubjectivity and neuroscience, to also learn from and adapt for families with different heritage, identity, and experience.

As the family testify, the experience of DDP is scary, amazing, transformative, and challenging.

First, to determine the feasibility of providing a simple educational intervention using the HEEAL (Honesty, Empathy, Educate, Apology/awareness, Lessen the chance for future errors) mnemonic. Second, to assess the intervention’s ability to improve communication self-efficacy, knowledge and objective measures of error disclosure competence among providers.

A 1-day (6-hour) pilot medical error curriculum was created to teach the HEEAL method of medical error disclosure to both patients and peers who have committed errors. The four-part curriculum consists of pre-intervention evaluation, HEEAL content lecture, rapid cycle deliberate practice (RCDP) with debriefing and post-intervention evaluation. This curriculum was repeated twice. The first training focused on medical error disclosure to patients’ families and the second on medical error disclosure to involved peers. Participating faculty developed, adapted and piloted simulation cases, skills checklists and knowledge questionnaires. The barriers to error disclosure assessment (BEDA) tool served as our confidence survey. Five additional questions developed and piloted by the research team were administered with the BEDA to assess learner confidence with peer–peer disclosure. Pre- and post-intervention written measures of knowledge and confidence (BEDA) were obtained for both iterations of the curriculum. Assessment of observed clinical skills was scored by the involved SP (standardized patient) immediately following the RCDP. An

Fourteen learners completed all curricular components. Learners demonstrated statistically significant improvement in their confidence in medical error disclosure (

This pilot data suggest that the HEEAL intervention provides an effective and efficient way for medical educators to teach senior medical students how to provide competent error disclosure to both patients and peers.
Fósiles del morro de Arica
Authors: Escutti Orrego Alfredo
Published: October 2023

Latitud 18° 29' S. long. 70° 20' O. El examen de estas conchas confirma plenamente la opinión, ya aceptada, de la existencia de rocas jurásicas en la América del Sur. La forma mas característica de estos fósiles es una valva de Braquiópodo, bien conservada, perteneciente al género Rhynchonella, que por su forma y estructura parece ser la Rhynchonella tetrahedra, especie característica del terreno liásico europeo, y que he encontrado igualmente en las margas calcáreas de Manflas (valle de Copiapó) del Lías superior. En la especie del Morro los pliegues laterales se hallan encorvados y están separados de los de la región media por una área llana, como en la Rhynchonella tetrahedru.

Contribución a la anatomía de los octodontidos
Authors: Mann Fischer Guillermo
Published: October 2023

La familia de los octodóntidos es, dentro del orden de los roedores, una de las más variadas, de las menos homogéneas. Sera, pues, interesante examinar si las diferencias existentes entre los géneros que se han reunido en esa familia, pueden considerarse como meras modificaciones secundarias del tipo general de los octodóntidos.

Galaxias maculatus (Jenyns) en Chile, con especial referencia a su reproducción
Authors: Campos C. Hugo
Published: October 2023

Galaxias maculatus (Jenyns) es una especie de agua dulce cuya reproducción está relacionada con la dinámica de los estuarios y con la migración de los estadios juveniles y adultos. Este mecanismo tiene especial importancia por la interesante distribución geográfica de la familia Galaxidae, circunscrita a los extremos del hemisferio sur: Australia, Nueva Zelandia, Tasmania, Peninsula del Cabo en Sudáfrica y cono sur de Sudamérica en Argentina y Chile. La especie G. maculatus está representada en toda esta área a excepción de Sudáfrica. Este hecho plantea una interrogante respecto al mecanismo que siguió la especie en su distribución dentro de esta vasta área. Estudios de la reproducción de esta especie en puntos extremos de su área de distribución permiten dar valiosos antecedentes para la hipótesis general de su origen.
Análisis biogeográfico de la flora algológica de Antofagasta (norte de Chile)
Authors: Ramírez María Eliana , Santelices Bernabé
Published: October 2023

El presente trabajo tiene como objetivo analizar la validez de caracterizaciones fitogeográficas recientes de la costa de Chile. Para ello se realizó un intenso muestreo y nuevos estudios taxonómicos de la flora ficológica en hábitats inter y submareales de ocho puntos de la costa de Antofagasta (23° 40' S, 70° 25' O). Se señala la presencia de 70 especies de macroalgas para la zona. Catorce de ellas constituyen extensiones de rango ocho de las cuales son especies encontradas por primera vez en Sudamérica. Los resultados obtenidos se confrontan con el esquema fitogeográfico existente. Los porcentajes en que aparecen representados los distintos grupos florísticos concuerdan con las caracterizaciones fitogeográficas establecidas para este sector de la costa de Chile.
Paleomegaflora de la Formación Navidad, Miembro Navidad (Mioceno), en el área de Matanzas, Chile Central occidental

Published: October 2023

En el presente artículo se da cuenta del estudio sistemático de improntas foliares procedentes de dos niveles fosilíferos del miembro Navidad de la formación homónima, en la localidad de Matanzas (VI Región, Chile). Esta formación ha sido asignada al Mioceno Inferior alto hasta el Mioceno Superior inicial. Sesenta y tres órgano-especies son determinadas y descritas. Se discute el carácter de cada conjunto fósil y se interpreta su significado, postulándose que se trata de floras mixtas y que representan un cambio florístico caracterizado por una reducción de la diversidad de especies de Nothofagus. Se compara esta información con los antecedentes aportados por las asociaciones de foraminíferos planctónicos.

THE IMPACT OF EXTERNAL FACTORS ON THE PROCESSES OF TRANSFORMATION OF BANKS IN THE CONTEXT OF THE DIGITAL ECONOMY
Authors: Erdonaev Аlikul
Published: October 2023

This article considers the issues of forming new standards in banking business based on the factors of liberalization of foreign economic relations, capital and production transnationalization, which affect the processes of transformation of commercial banks in the conditions of the digital economy. The information revolution is creating additional risks for banks through international business and exchange rates. Today, banks are faced with completely new phenomena and tasks such as data processing under the influence of "Big data", the emergence of new participants in the financial market, all this leads to an increase in the risks of commercial banks in the market, and this, in turn, requires the transformation of banks' activities is doing.
The Spatial Distribution of Out-of-Hospital Cardiac Arrest and the Chain of Survival in Ireland: A Multi-Class Urban-Rural Analysis.
Authors: Masterson Siobhán , Cullinan John , Teljeur Conor , Vellinga Akke
Published: October 2023

Cardiac arrest occurs when the heart suddenly ceases to pump blood around the body. To optimise survival from out-of-hospital cardiac arrest (OHCA), knowledge of the spatial distribution of OHCA and the availability of resuscitation, or ‘Chain of Survival’, is required. Thus, this study aims to describe OHCA incidence and Chain of Survival availability in a manner that can help inform pre-hospital planning in the Republic of Ireland. In view of Ireland’s heterogeneous settlement pattern, we analyse the association between varying degrees of rurality, OHCA incidence and the availability of the Chain of Survival. In addition to population density, settlement size, proximity to urban centres and land use is taken into account which results in six classes: city; town; accessible village; remote village; accessible rural; remote rural. Results show that, when adjusted for age and sex, the incidence of adult OHCA decreases with increasing rurality. Furthermore, while distance to the nearest ambulance station and call-response interval is greater with increasing rurality, the lowest levels of bystander cardiopulmonary resuscitation occur in the most urban class. To the best of our knowledge, this is one of the very first whole-country geographic descriptions of OHCA to be performed internationally. It is also the first OHCA study to use a multi-class urban-rural classification that considers rurality as more than a function of population density.
A Geography of Marine Plastics
Authors: Black Jeffrey , Holmes Dakota , Carr Liam
Published: October 2023

Marine plastics have gained infamy as one of the most pressing environmental issues of our time. Their lightweight and durable properties, and low cost of production have made them an attractive material for packaging and shipping. This production-side preference for cheap plastic products and packaging, coupled with consumption preferences for pre-packaged, single-use goods that ultimately overwhelm increasingly costly waste management efforts, has resulted in a persistent, ubiquitous presence of plastic materials globally. Grounded in an extensive review of the literature, this paper reviews the geography of marine plastics research, and the pervasive and persistent effects of plastic on the marine system to aid the discussions of comprehensive mitigation measures. The discussion points raised in this paper highlight the need for a global systems perspective that considers geography, environmental impacts, and sources in order to develop effective mitigation responses to marine litter.
