Published: April 2024

PurposeArtificial intelligence is one of the most significant and active fields of study in the last few years. Artificial intelligence-derived robotic technologies known as chatbots are gaining interest from both academic and industry sectors. By analyzing the development and patterns of research on the chatbot phenomena within the tourism field, this study seeks to develop a theoretical framework for the interaction between chatbots and tourism.Design/methodology/approachThe Web of Science (WoS) database’s 33 articles on chatbots related to travel and hospitality were examined between 2019 and 2024 using VOSviewer software for bibliometric and thematic content analysis.FindingsResearch on chatbots for tourism and hospitality appears to be in its early stages. The factors influencing tourists' intentions to use chatbots have been thoroughly researched; the attitudes, perceptions and behavioral intentions of destinations, travel agencies and restaurant patrons regarding chatbots were examined, and it was found that the quantitative research approach was dominant. In addition, the majority of the studies are based on a particular theory or model.Originality/valueThis is one of the first attempts to directly comprehend and depict the interconnected structures of studies on the interaction between chatbots and tourism through the use of network analysis. Furthermore, the study’s findings can offer academics a comprehensive viewpoint and a reference manual for more accurate assessment and oversight of the chatbot-tourism interaction. Regarding the lack of research on the topic and the fragmented structure of the studies that exist, it is imperative to provide both a comprehensive overview and a roadmap for future investigations into the usage of chatbots in the travel and hospitality sector.

Purpose
This study aims to provide an alternative adoption to overcome the energy crisis and environmental effluence by comparative theoretical and trial testing analysis of an innovative combined condenser unit over traditional individual condenser unit water heating systems.

Design/methodology/approach
The presented innovative new unit of the combined condenser heat pipe works efficiently through its improved idea and unique design, providing uniform heating to improve the heat transfer and, finally, the temperature of water increases without enhancing the cost. In this design, all these five evaporator units were connected with a single combined condenser unit in such a manner that after the condensation of heat transfer fluid vapour, it goes equally into the evaporator pipe.

Findings
The maximum temperature of hot water obtained from the combined condenser heating system was 60.6, 55.5 and 50.3°C at a water flow rate of 0.001, 0.002 and 0.003 kg/s, respectively. The first and second law thermodynamic efficiency of the combined condenser heating system were 55.4%, 60.5% and 89.0% and 2.6%, 3.7% and 4.1% at 0.001, 0.002 and 0.003 kg/s of water flow rates, respectively. The combined condenser heat pipe solar evacuated tube heating system promoting progressive performance is considered efficient and environment-friendly compared to the traditional condenser unit water heating system.

Originality/value
Innovative combined condenser heat pipe evacuated tube collector assembly was designed and developed for the study. A comparative theoretical and experimental energy-exergy performance analysis was performed of innovated collective condenser and traditional individual condenser heat pipe water heating system at various mass flow rate.

Published: April 2024

AbstractS‐wave velocity plays a crucial role in various applications but often remains unavailable in vintage wells. To address this practical challenge, we propose a machine learning framework utilizing an enhanced bidirectional long short‐term memory algorithm for estimating S‐wave sonic logs from conventional logs, including P‐wave sonic, gamma ray, total porosity, and bulk density. These input logs are selected based on traditional rock physics models, integrating geological and geophysical relations existing in the data. Our study, encompassing 34 wells across diverse formations in the Delaware Basin, Texas, demonstrates the superiority of machine learning models over traditional methods like Greenberg–Castagna equations, without prior geological and geophysical information. Among these machine learning models, the enhanced bidirectional long short‐term memory model with self‐attention yields the highest performance, achieving an R‐squared value of 0.81. Blind tests on five wells without prior geologic information validate the reliability of our approach. The estimated S‐wave velocity values enable the creation of a basin‐scale S‐wave velocity model through interpolation and extrapolation of these prediction models. Additionally, the bidirectional long short‐term memory model excels not only in predicting S‐wave velocity but also in estimating S‐wave reflectivity for seismic amplitude variation with offset applications in exploration seismology. In conclusion, these S‐wave velocity estimates facilitate the prediction of further elastic properties, aiding in the comprehension of petrophysical and geomechanical property variations within the basin and enhancing earthquake hypocentral depth estimation.
Making home alive again after war: AcoliKaka’s Indigenous land sovereignties in Northern Uganda
Authors: Rosenoff Gauvin Lara 
Published: April 2024

AbstractAfter the war between the Ugandan government and the Lord's Resistance Army (1986‐2006), 90 per cent of the displaced rural population in Northern Uganda returned to small‐scale farming on their ancestral lands and their systems of communal land stewardship. At the time, there was much debate about transitional justice interventions to address war's violence, but in that same period over 85 per cent of Acoli chiefdoms saw affiliated clans, or kin‐based political communities (kaka), negotiate to write down their Indigenous governance constitutions for the first time. AcoliKaka’s return to their ancestral lands and small‐scale farming, and subsequent engagements withtekwaro –Indigenous knowledge –through constitution writing, served to strengthen Indigenous governance and law after their weakening in contexts of war and displacement. It is argued here that these engagements and negotiations rooted in the land, regardless of their outcomes, served to orient relationshipsawayfrom the fragmenting, unprecedented, forced Acoli‐on‐Acoli violence experienced during the war. A resurgence of AcoliKaka’s Indigenous law and governance rooted in communal land stewardship is linked to relational repair and supports calls for transitional justice processes to nurture and respect Indigenous land rights. These ethnographic arguments also lend support tokaka’s ongoing efforts towards clan unity (ribbe kaka) and to secure communal land sovereignties.
Inter‐observer variation of head and foot point selection for subject height determination
Authors: Liscio Eugene , Lim Jihwa 
Published: April 2024

AbstractThe purpose of this study was to examine factors affecting video analysts' decisions in marking the vertex of the head and foot point and corresponding inter‐observer marking variances when conducting height analysis on individuals seen in video. Nineteen video analysts participated in an exercise at the 2022 Ontario Forensic Video Analysts' Association (OFVAA) conference where they were asked to mark the vertex of the head and a corresponding foot point of a “suspect” on extracted video frames in a variety of positions and with different headwear (no headwear, baseball cap, and hoodie). A height scale with discrete marking points located at the same positions as where the suspect was positioned was also included in a separate image set, offering a comparison to the suspect. Marked points for all analysts were overlayed onto the respective image frame for visual observations. Summary statistics were used for data interpretation. This study demonstrated that factors such as the suspect's proximity to the camera and suspect's headwear affected the variability and range of marking, which has a direct correlation to the estimated height of the suspect. In general, when the region to be marked was larger, the variability was also larger. This study also demonstrates that marking errors were significantly reduced when discrete marking locations were present such as on a height scale. The average percentage difference of height was most notable, approximately 3%, when the suspect was wearing a hoodie and was at a position closest to the camera. The range of the percentage difference was also the highest at this position, which was 10.6%. In comparison, the height scale had a maximum percent height difference of 0.6% at position D‐5, the furthest position from the camera. The range at this location was approximately 2%, which was also the highest range value for the height scale. Future studies should consider suspect posture and look at how these errors may be minimized by examining the best locations to mark the head and foot points under different scenarios.

Authors: Hu Xiaolu , Zhong Angel , Cao Youdan , Wang Wenlan 
Published: April 2024

AbstractThis study explores the influence of air pollution on the corporate bond market in China. An air pollution premium is documented, whereby bonds issued in more polluted areas are associated with higher offering yields at issue in the primary market and higher yield spreads in the secondary market. The statistically and economically significant air pollution premium is robust to a battery of sensitivity checks. The air pollution premium is associated with rising investor attention to climate risk in financial markets.
Endodontic management considerations for Type III dens invaginatus based on anatomical characteristics: A case series
Authors: Wang Jia , Niu Chenguang , Zhang Pengfei , Ran Shujun , Huang Zhengwei 
Published: April 2024

AbstractDens invaginatus (DI) is a developmental anomaly of the teeth characterised by the in‐folding of the enamel into the dentin. Oehlers' Type III DI is the most serious form, in which the inherently invaginated channels communicate with periodontal and dental pulp tissue, increasing the risk of bacterial contamination. However, varying and complex anatomical features make diagnosis and treatment challenging. Conventional endodontic therapies promote healing by avoiding unnecessary interventions (e.g., surgical or other invasive treatments). Radiographic examination can reveal the structural details of such malformations. We obtained multiple procedural details for treating Type III DI based on radiographic analyses from our clinical experience. In addition, we introduce a new classification strategy for the management of Type III DI that is more applicable to treatment needs. This study aimed to discuss the anatomical features and current treatment considerations of Type III DI.
A parametric study on pulse duplicator design and valve hemodynamics

Published: April 2024

AbstractBackgroundIn vitro assessment is mandatory for artificial heart valve development. This study aims to investigate the effects of pulse duplicator features on valve responsiveness, conduct a sensitivity analysis across valve prosthesis types, and contribute on the development of versatile pulse duplicator systems able to perform reliable prosthetic aortic valve assessment under physiologic hemodynamic conditions.MethodsA reference pulse duplicator was established based on literature. Further optimization process led to new designs that underwent a parametric study, also involving different aortic valve prostheses. These designs were evaluated on criteria such as mean pressure differential and pulse pressure (assessed from high‐fidelity pressure measurements), valve opening and closing behavior, flow, and regurgitation. Finally, the resulting optimized setup was tested under five different hemodynamic settings simulating a range of physiologic and pathologic conditions.ResultsThe results show that both, pulse duplicator design and valve type significantly influence aortic and ventricular pressure, flow, and valve kinematic response. The optimal design comprised key features such as a compliance chamber and restrictor for diastolic pressure maintenance and narrow pulse pressure. Additionally, an atrial reservoir was included to prevent atrial–aortic interference, and a bioprosthetic valve was used in mitral position to avoid delayed valve closing effects.ConclusionThis study showed that individual pulse duplicator features can have a significant effect on valve's responsiveness. The optimized versatile pulse duplicator replicated physiologic and pathologic aortic valve hemodynamic conditions, serving as a reliable characterization tool for assessing and optimizing aortic valve performance.
Extracellular acidification increases uterine contraction in pregnant mouse by increasing intracellular calcium
Authors: Almohanna Asmaa M. , Noble Karen , Wray Susan 
Published: April 2024

AbstractAimsAs uterine extracellular pH decreases during the ischemic conditions of labor, but its effects on myometrial contraction are largely unknown, there is a need to elucidate its physiological effects and mechanisms of action. Furthermore, it is not known if any of the effects of extracellular acidification are affected by pregnancy, thus we also determined how gestation affects the response to acidification.MethodsNonpregnant, mid‐, and term‐pregnant myometrial strips were obtained from humanely killed mice. Contractions were recorded under spontaneous, depolarized, and oxytocin‐stimulated conditions. The extracellular pH of the perfusate was changed from 7.4 to 6.9 or 7.9 in HEPES‐buffered physiological saline. Intracellular pH was measured using SNARF, and intracellular calcium was measured using Indo‐1. Statistical differences were tested using the appropriate t‐test.ResultsExtracellular acidification significantly increased the frequency and amplitude of spontaneous contractions in pregnant, but not nonpregnant, myometrium, whereas alkalinization decreased contractions. Intracellular acidification, via Na‐butyrate, transiently increased force in pregnant tissue. Intracellular pH was gradually acidified when extracellular pH was acidified, but extracellular acidification increased contractility before any significant change in intracellular pH. If myometrial force was driven by oxytocin or high‐K depolarization, then extracellular pH did not further increase force. Intracellular calcium changes mirrored those of force in the spontaneously contracting pregnant myometrium, and if calcium entry was prevented by nifedipine, extracellular acidification could not induce a rise in force.ConclusionExtracellular acidification increases excitability, calcium entry, and thus force in pregnant mouse myometrium, and this may contribute to increasing contractions during labor when ischemic conditions and acidemia occur.
Attributing extreme weather to climate change: State Park employees as institutional actors

Published: April 2024

AbstractResearchers in environmental psychology celebrate the potential for state and national parks to inspire civic engagement in the issue of climate change. Yet, prevailing conceptions of nature may reflect ongoing colonial concerns, such that parks may represent a space to avoid thinking about—rather than reckon with—escalating ecological crises. In this paper, we approach the topic of climate change in state parks from a perspective informed by decolonial theory. In particular, we report a mixed‐methods study with (N = 51) employees at parks in Kansas and throughout the United States regarding the extra‐individual factors that impact their tendency to subjectively attribute extreme weather to climate change. Findings indicate that park employees were less likely to attribute extreme weather to climate change in parks with (1) less institutional support for climate change mitigation, and (2) increased presence of white conservatives. Responses to a question about the purpose of parks and open‐ended reflections reveal that employees conceive of parks as a space for recreation wherein their primary role in relation to visitors is to supply “fun” and “natural” experiences for consumption. We reflect on conceptions of parks and nature and discuss a conception of parks better suited to confront the escalating ecological crisis.
Advancements in medical research using fetal sheep: Implications for human health and treatment methods
Authors: Abe Tomoyuki , Sarentonglaga Borjigin , Nagao Yoshikazu 
Published: April 2024

AbstractSheep are typically considered as industrial animals that provide wool and meals. However, they play a significant role in medical research in addition to their conventional use. Notably, sheep fetuses are resistant to surgical invasions and can endure numerous manipulations, such as needle puncture and cell transplantation, and surgical operations requiring exposure beyond the uterus. Based on these distinguishing characteristics, we established a chimeric sheep model capable of producing human/monkey pluripotent cell‐derived blood cells via the fetal liver. Furthermore, sheep have become crucial as human fetal models, acting as platforms for developing and improving techniques for intrauterine surgery to address congenital disorders and clarifying the complex pharmacokinetic interactions between mothers and their fetuses. This study emphasizes the significant contributions of fetal sheep to advancing human disease understanding and treatment strategies, highlighting their unique characteristics that are not present in other animals.

Published: April 2024

AbstractObjectivesIndividuals with bipolar disorders (BD) have heterogenic pre‐onset illness courses and responses to treatment. The pattern of illness preceding the diagnosis of BD may be a marker of future treatment response. Here, we examined associations between psychiatric morbidity preceding the diagnosis of BD and pharmacological treatment patterns in the 2 years following diagnosis.MethodsIn this register‐based study, we included all patients with a diagnosis of BD attending Danish Psychiatric Services between January 1, 2012 and December 31, 2016. We examined the association between a diagnosis of substance use disorder, psychosis (other than schizophrenia or schizoaffective disorder), unipolar depression, anxiety/OCD, PTSD, personality disorder, or ADHD preceding BD and pharmacological treatment patterns following the diagnosis of BD (lithium, valproate, lamotrigine, antidepressants, olanzapine, risperidone, and quetiapine) via multivariable Cox proportional hazards regression adjusted for age, sex, and year of BD diagnosis.ResultsWe included 9594 patients with a median age of 39 years, 58% of whom were female. Antidepressants, quetiapine, and lamotrigine were the most commonly used medications in BD and were all linked to prior depressive illness and female sex. Lithium was used among patients with less diagnostic heterogeneity preceding BD, while valproate was more likely to be used for patients with prior substance use disorder or ADHD.ConclusionThe pharmacological treatment of BD is linked to psychiatric morbidity preceding its diagnosis. Assuming that these associations reflect well‐informed clinical decisions, this knowledge may inform future clinical trials by taking participants' prior morbidity into account in treatment allocation.
