Abstract
The use of regional kinematic reference frames (mRFs) in seismic zones is uncommon worldwide. This article proposes a solution implemented for Chilean mining, whose current projects are based on the classic reference frames (PSAD56 and SAD69). The approach is to move from a classic reference frame to an mRF in seismic countries where earthquakes constantly alter the frame. Our research group calculated an mRF (REDGEOMIN) that includes interseismic, coseismic, and postseismic deformation using CORS with open data from 2009 to 2022 and processed with scientific standards global navigation satellite system. REDGEOMIN consists of a deformation model (ADELA) with an interpolation approach through thin plate spline, allowing the greatest deformation to be modelled at campaign points. The relationship between classical and modern systems was explored with conformal transformations and NTv2 grids to include deformations, especially coming from PSAD56 and SAD69. The results demonstrate that REDGEOMIN aligns with the IGb14 reference frame (<1.0 mm), SIRGAS (ENU = 1.0, 1, 0, 2.0 mm), and the Chilean national reference frame SIRGASChile@2021.00 (ENU = 1, 2, 1, 6, 4.3 mm) aligns with millimetric precision. ADELA deformation model accurately models period locations to within 5 mm. Densification of REDGEOMIN@2022.00 at passive points PSAD56/SAD69 shows centimetric precision. PSAD56/SAD69, adjusted in the 1970s, are outdated due to crustal movement and seismic events and have metric errors. Therefore, different types of transformations were evaluated between PSAD56/SAD69 and REDGEOMIN@2022, whose RMS is between 1.57 and 1.69 m, and national grid transformations (NTv2) with an RMS of 0.23 and 0.16 m for PSAD56 and SAD69, respectively. The relationship between the classic systems and REDGEOMIN allows the transformation of the entire Chilean mining cadastre to epoch 2022.00. Starting in 2022.00, REDGEOMIN/ADELA offers millimetre precision, which is crucial in seismic zones. Furthermore, it paves the way to implement an updated national-level mRF in case of seismic events. Currently, Chilean mining laws are rigid, geodesically speaking. Therefore, legal-technical suggestions for implementing REDGEOMIN are also included in this article.
Why do women choose home births
Authors: Grünebaum Amos , Chervenak Frank A. 
Published: May 2024

Abstract
In recent years, the US has seen a significant rise in the rate of planned home births, with a 60 % increase from 2016 to 2023, reaching a total of 46,918. This trend positions the US as the leading developed country in terms of home birth prevalence. The American College of Obstetricians and Gynecologists (ACOG) suggests stringent criteria for selecting candidates for home births, but these guidelines have not been adopted by home birth midwives leading to poor outcomes including increased rates of neonatal morbidity and mortality. This paper explores the motivations behind choosing home births in the US despite the known risks. Studies highlight factors such as the desire for a more natural birth experience, previous negative hospital experiences, and the influence of the COVID-19 pandemic on perceptions of hospital safety. We provide new insights into why women choose home births by incorporating insights from Nobel laureate Daniel Kahneman’s theories on decision-making, suggesting that cognitive biases may significantly influence these decisions. Kahneman’s work provides a framework for understanding how biases and heuristics can lead to the underestimation of risks and overemphasis on personal birth experiences. We also provide recommendations (“nudges according to Richard Thaler”) to help ensure women have access to clear, balanced information about home births. The development of this publication was assisted by OpenAI’s ChatGPT-4, which facilitated the synthesis of literature, interpretation of data, and manuscript drafting. This collaboration underscores the potential of integrating advanced computational tools in academic research, enhancing the efficiency and depth of our analyses.

Abstract
Exploring the non-Hermitian properties of semiconductor materials for optical applications is at the forefront of photonic research. However, the selection of appropriate systems to implement such photonic devices remains a topic of debate. In this work, we demonstrate that a perovskite crystal, characterized by its easy and low-cost manufacturing, when placed between two distributed Bragg reflectors with an air gap, can form a natural double microcavity. This construction shows promising properties for the realisation of novel, tunable non-Hermitian photonic devices through strong light–matter coupling. We reveal that such a system exhibits double-coupled polariton modes with dispersion including multiple inflection points. Owing to its non-Hermiticity, our system exhibits nonreciprocal properties and allows for the observation of exceptional points. Our experimental studies are in agreement with the theoretical analysis based on coupled mode theory and calculations based on transfer matrix method.
A facile and efficient one-pot 3-component reaction (3-CR) method for the synthesis of thiazine-based heterocyclic compounds using zwitterion adduct intermediates
Authors: Mohlala Reagan L. , Coyanis E. Mabel 
Published: May 2024

Abstract
Multicomponent reactions (MCRs) are considered a green strategy by generating diversity of scaffolds from less synthetic effort and safe conditions. This work present the synthesis of dimethyl 8-(tert-butylamino)-4-oxo-4,6-dihydropyrimido[2,1-b][1,3]thiazine-6,7-dicarboxylate in low to moderate yields 33–74 % from the prepared 2-amino-4H-1,3-thiazin-4-one derivatives containing both an acidic proton and a suitable nucleophile with alkyl isocyanides and DMAD/DEtAD. The work portrays facile method under green chemical production processes using green solvents such as acetone, ethanol, isopropanol, and 2-methyl-tetrahydrofuran. This chapter shows the flexibility of zwitterion adduct from the reaction of alkyl isocyanide and DMAD. The zwitterion adduct is trapped by 2-amino-4H-1,3-thiazin-4-one derivatives and forms fused [6-6] heterocyclic compounds. The preparation of starting material thiazine was carried out at different condition from 0 °C temperatures to reflux, while the synthesis of novel dimethyl 8-(tert-butylamino)-4-oxo-4,6-dihydropyrimido[2,1-b][1,3]thiazine-6,7-dicarboxylates was done at room temperature without the use of catalyst.
Performance analysis of a gas turbine engine with intercooling and regeneration process - Part 1
Authors: Quadros Jaimon D. , Thalambeti Prashanth , Ndiaye Mamadou , Mogul Yakub I. 
Published: May 2024

Abstract
Auxiliary systems, such as regeneration and intercooling, have been integrated with the primary gas generator to improve power production and fuel economy in modern gas turbine power plants. Implementing these techniques in turbine engines is challenging due to size, weight, and complex flow patterns. A solution is to use a turboprop engine with a smaller mass flow rate and simpler gas paths. The current study involves the numerical analysis of performance parameters namely, specific power (SP), thermal efficiency (η), and enthalpy based specific fuel consumption (EBSFC) of a turboprop engine using thermodynamic parameters namely, pressure ratio (PR), nozzle pressure ratio (NPR), turbine inlet temperature (TIT), regeneration efficiency (R), and intercooling efficiency (E). The results prove that the introduction of regeneration and intercooling showed significant improvement in the power developed, and reduced fuel consumption.

Abstract
The single crystals of bimetallic thiocyanate ligands, namely manganese cadmium thiocyanate (MCTC), zinc cadmium thiocyanate (ZCTC), manganese mercury thiocyanate dimethylsulphoxide (MMTD), and cadmium mercury thiocyanate dimethylsulphoxide (CMTD), are cultivated through the utilization of slow solvent evaporation and gradual cooling methodologies. Through the utilization of optical microscopic techniques such as field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), and epifluorescence, a state-of-the-art methodology extensively employed in the realms of biochemical, medical, and chemical research, we delve into the examination of growth mechanisms and surface topographies. It is additionally employed in LED, fluorescent, and various other luminous sources. The FESEM analysis of MCTC elucidates the manifestation of an extended dendritic growth pattern, which arises from the oscillation of the Mn and Cd metal ligands when connected by thiocyanate (SCN) bridges. The presence of three notable mounds exhibiting cavities within the multi-component thin film coating (MCTC) has been duly ascertained through the utilization of atomic force microscopy (AFM) imagery. The analysis of the histogram unveiled that the average diameter exhibited an augmentation concomitant with the alteration in the breadth of the distribution throughout the process of growth.
Individualising Antithrombotic Strategies for Acute and Chronic Coronary Syndromes
Authors: Storey Robert F 
Published: May 2024

For patients presenting with acute or chronic coronary syndromes, current guideline recommendations and expert consensus provide a range of options for antithrombotic treatment. The European Society of Cardiology 2023 guidelines on the management of acute coronary syndrome emphasise the need to assess the risk of both ischaemic events and bleeding. Those with high bleeding risk warrant particular consideration of the duration and intensity of antithrombotic therapy combinations. A joint consensus of experts takes a similar approach, informed by two network meta-analyses that appraised all available antithrombotic treatments within or after the 12 months following coronary revascularisation and/or acute coronary syndrome and individual participant data from six trials. In this article, four case studies are used to illustrate how these guidelines and expert consensus recommendations can be applied in clinical practice.
Potential of a laser pointer contact lens to improve the reliability of video-based eye-trackers in indoor and outdoor conditions

Published: May 2024

Many video-based eye trackers rely on detecting and tracking ocular features, a task that can be negatively affected by a number of individual or environmental factors. In this context, the aim of this study was to practically evaluate how the use of a scleral contact lens with two integrated near-infrared lasers (denoted CLP) could improve the tracking robustness in difficult lighting conditions, particularly outdoor ones.
We assessed the ability of the CLP (on a model eye) to detect the lasers and to deduce a gaze position with an accuracy better than 1° under four lighting conditions (1 lx, 250 lx, 50 klux and alternating 1lx /250 lx) on an artificial eye. These results were compared to the ability of a commercial eye tracker (Pupil Core) to detect the pupil on human eyes with a confidence score equal to or greater than 0.9.
CLP provided good results in all conditions (tracking accuracy and detection rates). In comparison, the Pupil Core performed well in all indoor conditions (99% detection) but failed in outdoor conditions (9.85% detection).
In conclusion, the CLP presents strong potential to improve the reliability of video-based eye-trackers in outdoor conditions by providing easy trackable feature.

The information-seeking behavior grounded on the situated cognition approach: an empirical and qualitative study
Abstract
This article presents an empirical and qualitative study that investigated the information-seeking behavior of persons in charge of organizational decision-making. In the first stage, an equivocal, unexpected and ill-defined decision-making situation was selected from situations described by managers of four medium-sized firms in Belo Horizonte city. In the second stage the six managers who lived the situation were interviewed in a semi-structured way. Analysis of the empirical data revealed that, in the specific situation, the information-seeking behavior of the executives was influenced by their life histories, their emotional dispositions and the relations and interrelations established with other subjects. It was argued that situated cognition is an innovative approach for the study of information-seeking behavior, which can contribute significantly to user studies in the field of information science.

Authors: Lucena Filho Gentil José , Villegas Margarita Maria Morales , Oliveira Sheila da Costa 
Published: May 2024

Neste trabalho, partimos de uma história de aprendizagem (HA) já escrita no formato original (segundo desenho originalmente formulado no Centro de Aprendizagem Organizacional do MIT) a qual foi objeto de uma dissertação no Mestrado em Gestão de Conhecimento e Tecnologia da Informação da Universidade Católica de Brasília. Analisamo-la com o objetivo de evidenciar se a mesma tem impacto na aprendizagem organizacional e se constitui instrumento para a gestão organizacional. Para a análise, utilizamos duas abordagens – a Ontologia da Linguagem de Flores / Echeverría, em uma acepção filosófica do termo “ontologia” (diferente da acepção usual comumente utilizada nas ciências de computação e informação), e a Teoria da Interpretação de Ricoeur – como meio de verificação de evidência de aprendizagem, tanto em nível de primeira ordem, quanto em nível de segunda ordem. Especificamente, os fenômenos observados são declarações de aprendizagem, tipologias conversacionais e fluxos emocionais presentes na narrativa que constitui a HA. Palavras-chave História de aprendizagem. Gestão organizacional. Ontologia da linguagem. Teoria da interpretação. Aprendizagem. Conversações. Stories on learning and organizational management: an ontological and hermeneutical approach Abstract This paper is based on a Story on Learning (according to an original work written in the Organizational Learning Center of Massachusetts Institute of Technology – MIT), which was the subject of a Master Degree dissertation on Knowledge Management and Information Technology, Catholic University of Brasilia. The analysis of this topic is to prove that it has an impact on the organizational learning and that it is an important instrument for Organizational Management. Two different approaches are analyzed: the Ontology of Language by Flores/Echeverría (ontology, a philosophy term, has here a different acceptation from the one used in Computer and Information Science) and Theory of Interpretation by Ricoeur, as a means for verifying the evidence of learning, both on firstorder level and second order. The conclusion is that the phenomena observed are statements of learning, conversational typologies and emotional flows present in the narratives of the story on learning. Keywords Learning history.

The aim of this review is to provide a precise estimation of infra-zygomatic crest (IZC) bone screw failure rate during orthodontic treatment. Data were obtained using the Cochrane Central Register of Controlled Trails (central), PUBMED, EMBASE, google scholar, OVID, Wiley library till 1 January 2022. The titles and abstract of the electronic search were screened and evaluated by two observers according to the inclusion and exclusion criteria. This review was enrolled in PROSPERO (registration ID number CRD42020206610). There were 1725 records identified through electronic and 1 additional record identified through manual search. After 377 duplicate removal, 1349 studies were screened on the base of title and abstract the final sample included 9 studies that meet the primary inclusion criteria were selected. Each study was assessed using the evaluation method described in the Cochrane handbook for systematic reviews. All studier collectively included of the 1238 IZC miniscrews. Included studies ranged from 20 to 772 IZC miniscrews and the average number was approximate 137 IZC miniscrews per study. The diameter of inserted IZC miniscrews ranged from 1.2 to 2.3 mm and length ranged from 6 to 17 mm. The recorded failure rate ranged from 0% to 47.2%, and the average failure rate for IZC miniscrew was 9.45% (with 95% CI [58.91; 93.82]).IZC miniscrew has low failure rate which suggest that IZC miniscrew are clinically reliable. Miniscrew are a stable anchorage for orthodontic tooth movement and zygomatic buttress of maxilla is suitable region for skeletal anchorage device placement.
