Published: August 2024

Moral decision-making typically involves trade-offs between moral values and self-interest. While previous research on the psychological mechanisms underlying moral decision-making has primarily focused on what people choose, less is known about how an individual consciously evaluates the choices they make. This sense of having made the right decision is known as subjective confidence. We investigated how subjective confidence is constructed across two moral contexts. In Study 1 (240 U.S. participants from Amazon Mechanical Turk, 81 female), participants made hypothetical decisions between choices with monetary profits for themselves and physical harm for either themselves or another person. In Study 2 (369 U.S. participants from Prolific, 176 female), participants made incentive-compatible decisions between choices with monetary profits for themselves and monetary harm for either themselves or another person. In both studies, each choice was followed by a subjective confidence rating. We used a computational model to obtain a trial-by-trial measure of participant-specific subjective value in decision-making and related this to subjective confidence ratings. Across all types of decisions, confidence was positively associated with the absolute difference in subjective value between the two options. Specific to the moral decision-making context, choices that are typically seen as more blameworthy – i.e., causing more harm to an innocent person to benefit oneself – suppressed the effects of increasing profit on confidence, while amplifying the dampening effect of harm on confidence. These results illustrate some potential cognitive mechanisms underlying subjective confidence in moral decision-making and highlighted both shared and distinct cognitive features relative to non-moral value-based decision-making.

The existence of ice-edge phytoplankton blooms in the Southern Ocean is well described, yet direct observations of the mechanisms of phytoplankton bloom development following seasonal sea-ice melt remain scarce. This study constrains such responses using biological and biogeochemical datasets collected along a coastal-to-offshore transect that bisects the receding sea-ice zone in the Kong Håkon VII Hav (off the coast of Dronning Maud Land). We documented that the biogeochemical growing conditions for phytoplankton vary on a latitudinal gradient of sea-ice concentration, where increased sea-ice melting creates optimal conditions for growth with increased light availability and potentially increased iron supply. The zones of the study area with the least ice cover were associated with diatom dominance, the greatest chlorophyll a concentrations, net community production, and dissolved inorganic carbon drawdown, as well as lower sea surface fugacity of CO2. Together, these associations imply higher potential for an oceanic CO2 sink due, at least in part, to more advanced bloom phase and/or larger bloom magnitude stemming from a relatively longer period of light exposure, as compared to the more ice-covered zones in the study area. From stable oxygen isotope fractions, sea-ice meltwater fractions were highest in the open ocean zone and meteoric meltwater fractions were highest in the coastal and polynya zones, suggesting that potential iron sources may also change on a latitudinal gradient across the study area. Variable phytoplankton community compositions were related to changing sea-ice concentrations, with a typical species succession from sympagic flagellate species (Pyramimonas sp. and Phaeocystis antarctica) to pelagic diatoms (e.g., Dactyliosolen tenuijunctus) observed across the study area. These results fill a spatiotemporal gap in the Southern Ocean, as sea-ice melting plays a larger role in governing phytoplankton bloom dynamics in the future Southern Ocean due to changing sea-ice conditions caused by anthropogenic global warming.

Published: August 2024

Path-integrated column measurements with a laser-absorption-based measurement system have been used to detect, locate, and quantify methane emissions from a series of single-blind controlled releases with no prior knowledge of timing, locations, or release rates. System performance was evaluated against metrics defined in the Continuous Monitoring Protocol established by the Colorado State University Methane Emissions Technology Evaluation Center (METEC). This protocol allows more direct comparison of system performance between disparate measurement technologies and is transferable to any test facility. To the authors’ knowledge, this work represents the first time the protocol has been directly applied at a test facility other than METEC. This experiment differs from similar tests where releases were conducted from equipment units at fixed locations at METEC by instead conducting releases at random locations anywhere within the central 0.18 km2 of a 0.35 km2 unobstructed test site. The releases were much shorter in duration than those conducted in similar testing at METEC. The system detected 25 of 42 releases with metered rates of 0.17–2.15 kg h−1. The minimum detected emissions rate was 0.22 kg h−1, and the system demonstrated a 100% detection rate for releases ≥0.65 kg h−1 when average wind speed was <5 m s−1. The test site was subdivided into 20 boxes (109 m × 83 m each), and the correct release box was identified in 9 cases, another 9 detections were localized to an adjacent box, and the remaining 7 were attributed elsewhere within the field. The average estimated emission rate bias was −6.1%. The 90% detection limit was 0.89 kg h−1, while the wind-normalized detection limit was 0.44 (kg h−1) (m s−1)−1.

Published: August 2024

Elucidating the mechanisms of action of steroid hormones will contribute to the development of therapeutic strategies for hormone-dependent tumors. Recent advances in genetic engineering have revealed the complex and diverse mechanisms of steroid hormone signaling; however, these techniques are limited to in vitro or animal experiments. It is believed that verifying hormone signals elucidated using human pathological tissue specimens will directly aid in treatment and diagnosis. However, pathological tissue specimens are generally formalin-fixed paraffin-embedded (FFPE), and protein/gene analyses of FFPE tissues are limited. Protein detection using immunohistochemistry with specific antibodies in FFPE tissues is a classical technique essential for diagnosis and treatment decisions in various types of cancer. In steroid hormone signaling, the expression and localization of receptors, hormone-related enzymes, and proteins encoded by response genes can be clarified using immunohistochemistry. Although protein-protein interactions such as receptor dimers and DNA-binding proteins are mainly detected in vitro, they can be examined in FFPE tissues using in situ proximity ligation assays and southwestern histochemistry, respectively. Using these detection methods, including immunohistochemistry, it is possible to analyze each hormone signaling pathway in hormone-related tumors histopathologically. Although FFPE tissues still suffer from gene and protein denaturation, their advantages include the ability to retrospectively study target factors/signals and obtain spatial information through microscopy. This review describes a visualization method for elucidating steroid hormone signaling in hormone-dependent tumors using FFPE tissues.

USE OF 3D PRINTING TECHNOLOGIES IN EXTERNAL RADIOTHERAPY FOR THE FABRICATION OF CUSTOMIZED BOLUS
Authors: Pérez Cualtán Camilo E. , Abril Andrea , Suarez Venegas Daniel R.
Published: August 2024

Radiotherapy has challenges for irregular tumors that extend to the skin surface; thus, boluses that act as tissue compensators are used in practice. However, conventional boluses are not adapted to the patient's anatomy or lack a dosimetry characterization, decreasing their effectiveness and precision. Given this situation, this study aimed to develop a method of characterization, design, and manufacturing boluses using 3D printing to improve dose coverage in the target volume in patients with head and neck cancer in photon beams. For this, a dosimetry characterization of the 3D printing material was performed through Hounsfield Units, and a novel experimental setup was proposed to determine the depth dose profiles depending on the 3D printing parameter: infill. Subsequently, a workflow was developed to fabricate bolus through the radiotherapy plan files, and finally, the effect of a printed bolus was evaluated with an anthropomorphic phantom. The results showed that the selected 3D printing material has similar characteristics to water (1.01 ± 0.04 g/cm³ and -115.39 ± 20 HU), making it suitable for clinical use and achieving a maximum dose of 7.8 mm with a 6 MeV beam. The ability of the workflow to generate and manufacture customized boluses adaptable to the patient's anatomy was also validated with an anthropomorphic head phantom manufactured in-house; the 95 % isodose curve in the simulation was on the target volume. It can be concluded that 3D printing technologies can design and manufacture structures comparable to commercial boluses, thus eliminating the discrepancy between the planned treatment and its execution in therapy.

Published: August 2024

El cambio climático y el uso de energías no renovables representan una amenaza mundial. Para mitigar este problema, la implantación de energías renovables, como la solar, está ganando popularidad. Sin embargo, para esta se necesitan grandes extensiones de terreno. En consecuencia, la tecnología agrivoltaica (APV) se presenta como una alternativa que combina la agricultura y la energía solar de forma beneficiosa y sinérgica. En este documento se evaluó la factibilidad de implementar cultivos de cacao en Cabuyaro, Meta, utilizando APV. Para ello, se diseñó un sistema conceptual teniendo en cuenta los requerimientos del cultivo y las características técnicas del municipio. Se simularon dos escenarios utilizando HOMER Pro: uno con APV operando como microrred aislada y otro conectado a la red. Se realizó un análisis económico de ambos casos, demostrando la viabilidad del sistema. Finalmente, el estudio concluye con una perspectiva sobre la utilidad de este concepto en el país.

„Vergoldete Frauen“ – Anmerkungen zu Zierplättchen aus Edelmetallen in der Vekerzug-Kultur
Authors: Kozubová Anita ,   Institute of Archaeology of the Slovak Academy of Sciences
Published: August 2024

This study deals with the findings of appliqués made of precious metals from the sites of the Vekerzug culture in Eastern Hungary and Southwestern Slovakia. Except for one hoard, the appliqués come from ten graves. Providing a more complex overview of these findings was at the center of our interest, focusing mainly on cultural and spatial analysis, their possible relation to specific gender or age categories of the burial individuals, and the importance of the appliqués for the costumes of the Vekerzug culture. All of their variants are unique to the Vekerzug culture and have no analogies in the neighboring regions, including the East European steppes and forest-steppes. Most of the appliqués in the Vekerzug culture are dated to the Late Hallstatt period or the Early La Tène period. The appliqués were found in the graves of adult females. Their costumes do not differ from the female costumes of the Vekerzug culture without appliqués. Most of the appliqués were found in richly furnished female graves, some of which are among the richest in the Vekerzug culture. Additionally, other objects made of precious metals in the Vekerzug culture, such as head ornaments and beads, were almost exclusively reserved for women.

The article discusses the results of excavations carried out in 2006–2009 at the Early Medieval barrow cemetery in Międzygórz. During the excavations, 5 burial mounds were identified. In all of them, cremation burials were found. In four cases, the burned remains of the deceased were scattered directly on the surface of the mounds or originally deposited in some organic containers, and in one example they were placed in a pottery urn placed on the top of the mound. There were also remains that could be associated with funeral ceremonies held at the cemetery and in honour of the dead. The cemetery should be dated to the 8th – 9th century.

ABSTRACT Objective: Tibial plateau fractures are common intra-articular fractures that pose classification and treatment challenges for orthopedic surgeons. Objective: This study examines the value of 3D printing for classifying and planning surgery for complex tibial plateau fractures. Methods: We reviewed 54 complex tibial plateau fractures treated at our hospital from January 2017 to January 2019. Patients underwent preoperative spiral CT scans, with DICOM data processed using Mimics software. 3D printing technology created accurate 1:1 scale models of the fractures. These models helped subdivide the fractures into seven types based on the tibial plateau's geometric planes. Surgical approaches and simulated operations, including fracture reduction and plate placement, were planned using these models. Results: The 3D models accurately depicted the direction and extent of fracture displacement and plateau collapse. They facilitated the preoperative planning, allowing for precise reconstruction strategies and matching intraoperative details with the pre-printed models. Post-surgery, the anatomical structure of the tibial plateau was significantly improved in all 54 cases. Conclusion: 3D printing effectively aids in the classification and preoperative planning of complex tibial plateau fractures, enhancing surgical outcomes and anatomical restoration.

ABSTRACT Objetive: This article presents a retrospective cohort study analyzing patients from IOT-FMUSP who underwent replantation or revision amputation procedures for traumatic thumb amputation between 2013 and 2020. Methods: The study included 40 patients in the replanted group and 41 patients in the amputed group. The patients were divided according to the level of amputation and their medical records were analyzed. Results: A total of 81 patients with digital amputation were analyzed, consisting of 79 males and 2 females, with mean ages of 43 and 49 for the amputed and replanted groups, respectively. According to the Biemer classification, 28.4% had proximal amputation, while 71.6% had distal amputation. The most common occupation was bricklayer (19.75%), and 80.24% were manual workers. Of the patients, 65% returned to their previous work, with 77.77% of them having amputation on their non-dominant hand, mostly caused by circular saw accidents (77.77%). The replantation success rate was 78%, with an average ischemia time of 9 hours and door-to-room time of 2 hours. Conclusion: the study findings revealed that traumatic thumb amputation predominantly affects working-age males with a low education level and the success rate of replantation was high in this ischemia time and door-to-room conditions.

ABSTRACT Objective: To compare the outcomes of surgical stabilization of pediatric supracondylar humeral fractures with the use of crossed Kirschner wires versus divergent lateral pinning wires. Methods: This is a systematic review with meta-analysis carried out by searching the MEDLINE/PubMed, Science Direct and Scielo databases. In these, the search for journals was carried out between January and August 2023, where 695 studies were found. To assess the quality of the studies, the Jadad and the MINORS scales were used.. The selection and reading of relevant articles were carried out by the researchers and 11 studies met the selection criteria. Results: From the 11 selected studies, 963 patients who met the criteria for the surgical treatment of these fractures were grouped. After the statistical analysis, we found that the ulnar nerve injury had a higher incidence when the crossed-K wire technique was used; and the lateral fixation is safer for the ulnar nerve. Conclusion: Both fixation techniques determine good functional results. However, fixation with lateral Kirschner wires proves to be safer considering the risk of iatrogenic injury to the ulnar nerve. Crossed-K wire fixation is more effective in terms of stability and maintenance of fracture reduction. Level of Evidence II, Systematic Review of Level II or Level I Studies with discrepant results.
Assessment of distribution of two sympatric mud crab species – Panopeus americanus and Panopeus austrobesus – in a Western Atlantic estuarine intertidal zone

Published: August 2024

Abstract Sympatric mud crab species Panopeus americanus and Panopeus austrobesus are found in intertidal environments associated with muddy and rocky habitats in the Western Atlantic coast. Therefore, they are a suitable model system to be used in studies focused on investigating biological coexistence aspects between close species, such as population structure and habitat. The aims of the current study are to describe and compare the distribution of two sympatric mud crab species – P. americanus and P. austrobesus – based on their spatial and temporal distribution, in a low human impact estuarine complex area. The hypothesis that these two species show similar distribution, although one species is more abundant than the other, was herein tested. Sampling was carried out in the intertidal zone of a specific area in Cananeia estuarine complex, São Paulo State, Southeastern Brazil, in different periods of time for two years. Both species presented similar pattern distribution and frequency, with predominance in the middle and high intertidal zones, including all demographic categories. However, Panopeus americanus was more abundant and presented smaller mean size in all sampling zones. The pronounced disparity in size between the species suggests divergent dietary preferences, potentially related to prey size allowing the coexistence of these sympatric and syntopic species. The predominance of these two species in the upper intertidal zones was understood as a strategy for avoiding competition with the intertidal alpheid shrimps.

ABSTRACT The Northeast region of Brazil is characterized by a tropical climate and high air temperatures, which can negatively affect the growth and physiological processes of strawberry plants (Fragaria x ananassa Duch) in the short- or long-term. In this context, the use of adapted varieties and technologies such as soil conditioners is necessary. Thus, the objective of this study was to assess the physiological responses and the thermal index of strawberry cultivars grown under hydrogel doses in the substrate. The study was conducted in a protected environment in Guaraciaba do Norte, Ceará state, Brazil, using a randomized block experimental design with four replicates, in a 5 × 2 factorial arrangement consisting of five hydrogel doses in the substrate (0, 1, 2, 3, and 4 g L-1) and two strawberry cultivars (‘Albion’ and ‘San Andreas’). Growth variables (number of leaves, crown diameter, and plant height) were evaluated at 15 and 45 days after transplanting (DAT). Gas exchanges (stomatal conductance, transpiration rate, CO2 assimilation rate, and intercellular CO2 concentration), physiological indices (intrinsic water use efficiency, instantaneous carboxylation efficiency, and instantaneous water use efficiency), and thermal index were evaluated at 90 DAT. Strawberry plant growth increased significantly as the hydrogel dose in the substrate was increased. The hydrogel dose of 4 g L-1 reduced gas exchanges at 90 DAT, regardless of the cultivar. Plants of the cultivar San Andreas showed higher intrinsic water use efficiency and lower thermal index when grown under the hydrogel dose of 4 g L-1.

ABSTRACT Salinity is one of the most limiting factors for agricultural productivity, as it affects both gas exchange and plant metabolism. However, with population growth and the constant search for alternatives to increase productivity, irrigation with water of moderate salinity appears to be feasible to enhance fruit cultivation in Brazil, especially in semi-arid regions, where most waters have high salt concentration and are the only available source for the producer. In this context, the objective of this study was to evaluate the effects of irrigation water salinity and harvest stages on gas exchange and post-harvest fruit quality of ‘Goldex’ yellow melon (Cucumis melo L.). The treatments consisted of two electrical conductivities of irrigation water (ECw - 0.8 and 4.0 dS m-1) and eight harvest stages (54, 56, 58, 60, 62, 64, 66, and 68 days after transplanting), arranged in a 2 × 8 factorial scheme and a completely randomized design. Under the salinity conditions imposed during the evaluation stages, the ‘Goldex’ yellow melon maintained its basic gas exchanges stable. The mass and number of fruits per plant were reduced by the salinity of the irrigation water, but the fruits continued to be classified as marketable, which makes irrigation with saline water up to 4.0 dS m-1 a viable alternative for the production of yellow melon, especially in regions where there is low availability of good quality water, which can enhance fruit growing in the semi-arid region.

ABSTRACT High salinity levels trigger harmful effects on plant mineral nutrition, causing production losses. The objective of this study was to evaluate effects of using pulse or continuous drip irrigation with brackish water on the accumulation and exportation of nutrients in peanut (Arachis hypogaea) crops. A randomized block experimental design with four replications was used, in a 6×2 factorial arrangement consisting of six levels of electrical conductivity of irrigation water (ECw: 0.2, 1.6, 2.8, 4.0, 5.2, and 6.4 dS m-1) and two irrigation regimes (pulse and continuous). Accumulation and exportation of macronutrients, sodium, and chloride were quantified at 63 days after sowing. Pulse irrigation mitigated the harmful effects of high salinity levels on peanut crops and promoted greater nutrient accumulation by plants compared to continuous irrigation. The descending order of nutrient accumulation by plants under pulse and continuous irrigation was: K > N > Ca > Mg > P > S. Pulse irrigation is effective in mitigating the detrimental effects of using brackish water on peanut crops.

Authors: Alaçam Barış , Vural Hatice , Orbay Metin
Published: August 2024

In this study, a photovoltaic system with an installed power of 10 kWp, which was built on the roof of a school cafeteria in Gümüşhacıköy district of Amasya, was modeled using the PVsyst software and PVSOL software. The real-life data of the system and the production data calculated from the software used were compared. While the actual total electricity production data of this photovoltaic system for 2021 was determined as 12.473 MWh, this value was obtained as 12.912 MWh using PVsyst software and 13.556 MWh using PVSOL software. While there was a 3.40% difference between the estimated production value and the real-life data with the PVsyst software, it was determined that there was a 7.99% difference between the estimated production value and the actual production value of the system as a result of the simulation made with PVSOL. From the production estimates made with two different simulation software, it was seen that the PVsyst software gave results closer to the real-life data.

The aim of this article is to present and discuss the creation process of the Oceanic Circuits database, centred on the mapping and analysis of petitions sent from Portuguese America to the Conselho Ultramarino (Overseas Council) and the Secretário de Estado da Marinha e do Ultramar (Secretary of State of the Navy and Overseas Territories) between 1736 and 1808. It proposes a reflection on the theoretical and methodological possibilities resulting from interdisciplinary dialogue between the areas of History and Data Systems. Initially, we present the historical sources held in the Arquivo Histórico Ultramarino (Overseas Historical Archive) in Lisbon that were selected for the research with the purpose of evidencing some of the main questions covered in the study, both in historiographic terms and in relation to the quantity and complexity of the data involved. Following this, we discuss the database pilot project, which was developed using a low code tool, signalling the potentials and limits of the application used. Finally, we look at the database specifically developed for an interdisciplinary team, discussing relevant aspects, as well as some of its characteristics.

Relevance One of the directions for increasing the efficiency of processes in the oil and gas industry is to optimize the consumption of electrical energy at all stages of production activity, with the main share of energy consumption costs occurring in processes associated with oil production. Currently, to assess and calculate the level of energy consumption and specific energy consumption, semi-empirical methods are used, characterized by the lack of an integrated approach and low accuracy. In this regard, the development of algorithmic and mathematical support for the implementation of an information-measuring system for determining the energy consumption of sucker rod pumping units is an urgent task. Aim of research The purpose of the work is to develop algorithmic and mathematical support for an information-measuring system for determining energy consumption to improve the accuracy of recording this parameter during the operation of wells equipped with sucker rod pumping units. Research methods The development of algorithmic and mathematical support was carried out using the fundamentals of theoretical mechanics, the theory of machines and mechanisms, the theoretical foundations of electrical engineering, the theory of electrical machines and devices, and systems theory. Results A kinematic analysis of a sucker rod pumping unit as an object consuming electricity is presented, on the basis of which a diagram of the sequence of transmission, conversion and loss of energy in individual elements and units of the installation is drawn up. A comparative analysis of existing methods for calculating electricity consumption, used in modern information-measuring systems for determining the energy consumption of sucker rod pumping units, was carried out, which showed an unacceptably high level of computational error. One of the options for mathematical and algorithmic support of the considered information-measuring system is proposed based on an analysis of all components of the installation and an individual calculation of the level of losses, the efficiency of each unit and element of the installation using the maximum number of technological parameters of the well and the technical characteristics of the equipment used. The use of the developed algorithmic and mathematical software made it possible to reduce the error in determining the energy consumption of a sucker rod pumping unit.

Las actividades que los alumnos realizan son un factor esencial para el aprendizaje en el aula de idiomas, y evaluar si las actividades cumplieron el objetivo con el que fueron planeadas se torna importante ya que hace más efectivo el proceso de enseñanza-aprendizaje. No obstante, los docentes no siempre son conscientes de la alineación de la actividad, el objetivo de aprendizaje y la evaluación del objetivo. En este sentido, el objetivo principal de este estudio fue identificar cómo los docentes evalúan los objetivos de aprendizaje de las actividades que incluyen en el aula. Esta metodología de investigación cualitativa descriptiva recopiló datos a través de entrevistas semiestructuradas. Los participantes fueron veinte profesores de inglés. El análisis de los datos se realizó mediante análisis de contenido iterativo. Los resultados mostraron que la evaluación de los objetivos de aprendizaje de las actividades pertenece principalmente a las categorías de hacer preguntas a los alumnos y usar el lenguaje. Se concluyó que con la evaluación se le da seguimiento al uso correcto del idioma y se realiza mediante la observación y monitoreo. Los hallazgos pueden deberse a que los profesores se enfocan en la corrección de errores y brindan retroalimentación inmediata.
Bridging the Communication Gap: Utilizing Large Language Models to Detect Emotional Distress and Depression in Adolescent Communication for Parental Support
Authors: Jeremie Ruvunangiza , C Valderrama
Published: August 2024

In the digital age, the communication gap between parents and adolescents has increased, presenting challenges to understanding the emotional well-being of their children. With the increasing prevalence of social networks, adolescents tend to express their feelings and struggles online rather than engage in face-to-face interaction. Existing monitoring tools allow parents to read messages and observe social media activity, but often fail to interpret the emotional content. Recent studies have explored the feasibility of using natural language processing and machine learning to predict depression based on social media activity. By analyzing the linguistic patterns, sentiments, and emotional content of online communication, researchers have demonstrated the potential to identify individuals suffering from depression at an early stage. This article proposes a novel solution that uses large language models (LLMs) to monitor and analyze adolescent communication on digital platforms, including smartphones and social media. The system aims to detect emotional distress, signs of depression, and other mental health indicators, providing timely alerts to parents. This technology enables parents to understand their teens’ emotions, offer the necessary support, and prevent the escalation of anxiety and depression.
Stevens-Johnson syndrome due to Lamotrigine
Authors: Silvio Espínola
Published: August 2024

Lamotrigine is an anticonvulsant drug that has been widely used to treat epilepsy, as a mood stabilizer (in cases of bipolar type 1 disorder), and in the management of neuropathic pain; It is used both in monotherapy and in complementary therapy. Considered a relatively new medication, approved by the Food and Drug Administration in 1994, its benefits include a greater margin of safety compared to other anticonvulsants; However, it causes serious adverse skin reactions, such as Stevens-Johnson syndrome. Approximately 8% of patients receiving lamotrigine develop a benign maculopapular rash during the first 4 months of treatment. A case of Stevens-Johnson syndrome caused by the drug is presented and a review of the condition and the probable pathways that trigger this delayed hypersensitivity immune response is carried out.
