Customer-Centric Dynamic Pricing for Free-Floating Vehicle Sharing Systems
Authors: Müller Christian , Gönsch Jochen , Soppert Matthias , Steinhardt Claudius 
Published: November 2023

Free-floating vehicle sharing systems such as car or bike sharing systems offer customers the flexibility to pick up and drop off vehicles at any location within the business area and, thus, have become a popular type of urban mobility. However, this flexibility has the drawback that vehicles tend to accumulate at locations with low demand. To counter these imbalances, pricing has proven to be an effective and cost-efficient means. The fact that customers use mobile applications, combined with the fact that providers know the exact location of each vehicle in real-time, provides new opportunities for dynamic pricing. In this context of modern vehicle sharing systems, we develop a profit-maximizing dynamic pricing approach that is built on adopting the concept of customer-centricity. Customer-centric dynamic pricing here means that, whenever a customer opens the provider’s mobile application to rent a vehicle, the price optimization incorporates the customer’s location as well as disaggregated choice behavior to precisely capture the effect of price and walking distance to the available vehicles on the customer’s probability for choosing a vehicle. Two other features characterize the approach. It is origin-based, that is, prices are differentiated by location and time of rental start, which reflects the real-world situation where the rental destination is usually unknown. Further, the approach is anticipative, using a stochastic dynamic program to foresee the effect of current decisions on future vehicle locations, rentals, and profits. We propose an approximate dynamic programming-based solution approach with nonparametric value function approximation. It allows direct application in practice, because historical data can readily be used and main parameters can be precomputed such that the online pricing problem becomes tractable. Extensive numerical studies, including a case study based on Share Now data, demonstrate that our approach increases profits by up to 8% compared with existing approaches from the literature.

Authors: Roberts Luke , Cooper Carolyn , Chipman Lee 
Published: November 2023

Background/AimsStudies have shown that using the clinical terminology SNOMED CT can improve clinical documentation, data quality and workforce productivity. This study aimed to evaluate the impact of a SNOMED CT-based digital tool on the quality, completeness and efficiency of clinical coding.MethodsA SNOMED CT-enabled clinical coding tool (SNOMED CT - Clinical Coding Assistant) was created. The tool used nursing assessments to identify relevant conditions that should be coded. SNOMED CT concepts and the nationally published SNOMED CT to ICD-10 cross-maps were compared to clinical coding data generated by the typical clinical coding and audit processes. The tool's impact on coding quality, completeness and productivity was assessed using various statistical measures. A total of 1681 coded hospital spells, representing 1589 patients, were included, across a 2-month period.ResultsUse of the SNOMED CT - Clinical Coding Assistant led to ICD-10 codes being added or changed in nearly half (n=773, 46.0%) of the hospital spells. The tool identified that over a third of the spells (n=588, 35.0%) had missing ICD-10 codes. The tool significantly reduced the time taken to find and validate the presence of numerous conditions for subsequent coding (P<0.001).ConclusionsUse of SNOMED CT-based tools can improve clinical coding accuracy, completeness and productivity. SNOMED CT has an important role to play in clinical coding transformation and effective system implementation is critical.

Published: November 2023

We design a broadband free space 2×4 90° optical hybrid over a spectral
window of 1000–1200 nm and 1470–1650 nm and verify the
feasibility of the scheme experimentally. The hybrid consists of three
broadband polarization beam splitters, an achromatic λ/4 wave plate, and three achromatic λ/2 wave plates. The fabricated hybrid
exhibits a good quadrature phase response with an interchannel
imbalance of 0.93–1.07 and a low phase deviation of less than 0.2°
under the typical communication wavelengths of 1064 nm and
C-band. The experimental results of the heterodyne method show that
the proposed hybrid can effectively solve the wavelength
incompatibility problem in satellite laser communication and realize
interconnection at different wavelengths. The designed hybrid (without
coupling) has a measured insertion loss of no more than 7.34 dB
at 1064 nm and C-band. A high-speed transmission experiment
with BPSK format has been conducted to verify the performance of the
assembled device.

Published: November 2023

Background and aimsHealthcare staff are at high risk of occupational exposure to Hepatitis B and other blood-borne diseases. Lack of education about the knowledge of Hepatitis B virus contributes to an increase in cases. This study aims to determine the knowledge of the Hepatitis B virus among the medical professionals in Duhok province, Kurdistan Region of Iraq, and to determine their knowledge of the importance of vaccination.Materials and methodsThis cross-sectional study was conducted in Duhok province, Kurdistan Region of Iraq, among medical science students from November 2022 to February 2023 and a total of 511 students participated in the study. A Self-administered questionnaire comprising 22 items categorized into five sections was distributed to the students either electronically or by paper and pen method. The survey utilized a Five-point Likert scale when assessing respondents’ opinions on knowledge, attitude, and practice (KAP). Microsoft Excel and GraphPad Prism 9 were used for statistical analysis.ResultsA total of 511 responses were collected from medical, dental, pharmacy, and laboratory students. The average age of the participants was 20.74 ±1.43 years. Among the respondents, only 96 (18.8%) were fully vaccinated against the Hepatitis B virus (received 3 or more doses of the vaccine), while 294 (57.5%) were not vaccinated. Lack of vaccination programs was the major reason for not receiving a vaccination (n = 182, 62%). About 286 (55.96%) of the participants had good knowledge, attitude, and practice on Hepatitis B, manifesting median scores of 26, 18, and 20, respectively.ConclusionIn our study, half of the students were found to be unvaccinated, mainly due to the absence of vaccination programs. Vaccinated students exhibited better knowledge, attitude, and practice toward the infection than non-vaccinated students. Therefore, we recommend the implementation of a vaccination program as well as training on infection prevention guidelines to increase awareness and encourage vaccination.

Published: November 2023

AimTo identify and systematically review current scholarship on talent management of international nurses in healthcare organizations.BackgroundAs nurse shortages persistently pose challenges for healthcare organizations globally, one of the primary strategies employed to address these shortages is employment of international nurses. To date little has been done to systematically review and collate contemporary research on talent management of this strategically important cohort. Talent management is a holistic construct that can support healthcare organizations to attract, develop, motivate, and retain talented employees to drive organizational performance. This systematic review isolates, appraises and collates available evidence on talent management practices for international nurses.Study designSystematic literature review.Data sourcesSearches of PubMed, EBSCO and Scopus were made covering literature from 2012–2022.Review methodsThis study followed Cochrane protocol for Systematic Reviews and key search terms were developed in consultation with University of Limerick library. As a key aim of the review was to provide evidence for the development of effective talent management practices, only peer-reviewed academic papers and empirical studies were included. Initial articles screening was conducted by two reviewers and full articles review was conducted by the entire research team. Findings were combined in a data extraction template for further analysis.ResultsThis review includes 62 articles thematically analysed under the headings recruitment and selection, retention and turnover, career progression, professional development, discrimination and racism, culture and communication.ConclusionNo articles were found that directly address talent management for international nurses. Although there are studies that address aspects of talent management independently, more research is required on talent management as a holistic process for international nurses to inform evidence-based practice.ImpactThis research emphasizes the importance of talent management for retention of international nurses in healthcare settings. It provides a knowledge base for healthcare organisations to enhance employee retention and ensure quality care for patients, as well as setting the foundation for future studies in this area.
Divergences and gaps in life expectancy and health-adjusted life expectancy in Mexico: Contribution analysis of the Global Burden of Disease Study 2019
Authors: Agudelo-Botero Marcela , Dávila-Cervantes Claudio A. , Velasco-Calderón Omar , Giraldo-Rodríguez Liliana 
Published: November 2023

IntroductionLife expectancy (LE) and Health-adjusted life expectancy (HALE) are summary indicators that reflect a population’s general life conditions and measure inequities in health outcomes. The objective of this study was to identify the differences in LE and HALE by sex, age group, and state in Mexico from 1990 to 2019. Also, to evaluate whether the changes in HALE are related to sociodemographic indicators and indicators of access to and quality of health services.MethodsA secondary analysis was performed based on the Global Burden of Disease, Injuries, and Risk Factors Study (GBD). Data were obtained for LE (by sex and state) and HALE (by sex, age group, and state) for the years 1990, 2010, and 2019. The correlations between HALE with the Socio-Demographic Index (SDI) and with the Healthcare Access and Quality (HAQ) Index were estimated for 1990 and 2019 (by total population and sex).ResultsLE and HALE had an absolute increase of 6.7% and 6.4% from 1990 to 2019, mainly among women, although they spent more years in poor health (11.8 years) than men. The patterns of LE and HALE were heterogeneous and divergent by state. In 2019, the difference in HALE (for both sex) between the states with the highest (Hidalgo) and the lowest (Chiapas) value was 4.6 years.ConclusionsProgress in LE and HALE has slowed in recent years; HALE has even had setbacks in some states. Gaps between men and women, as well as between states, are persistent. Public and population policymaking should seek to lengthen LE and focus on ensuring that such years are spent in good health and with good quality of life.
Laurencia mediterranea sp. nov. (Ceramiales, Rhodophyta) from the central Mediterranean Sea
Authors: Bartolo Angela G. , Zammit Gabrielle , Kytinou Eleni , Küpper Frithjof Christian 
Published: November 2023

Abstract
The identification of macroalgal species within the Laurencia complex is challenging, due to the presence of inconspicuous morphological characters, extensive variation in these traits and a diverse biogeography. Moreover, for a number of these species, no DNA sequence data are available in online databases. For this study, five algal specimens, tentatively assigned to Laurencia, were collected from Malta in the central Mediterranean Sea and studied using an integrative systematics approach. An analysis of the data resulted in the description of a new species, Laurencia mediterranea using combined morphological and molecular criteria, including COI-5P and rbcL. Morphologically L. mediterranea sp. nov. was distinct from other Laurencia spp. in the type of holdfast, the colour and shape of the thallus, the presence of secondary pit connections, lenticular thickenings and ‘corps en cerise’. Moreover, a new genetic species cluster indicated a separate taxon at the species level. Our study demonstrates that genetic sequences having clear links to sample metadata and digital herbaria are indispensable for macroalgal biodiversity research. This approach could offer a solution for algal taxonomy in cases where biogeography is important and limited sequence data exist in online DNA libraries.

Published: November 2023

Abstract
Species of the dinoflagellate genus Alexandrium are marine and planktonic forms, widely distributed, and some are recognized to form harmful algal blooms and to produce saxitoxins causing Paralytic Shellfish Poisoning in humans, and other toxins. We studied the species composition of Alexandrium in tropical and subtropical coastal areas of the Mexican Pacific: from the southern Gulf of California to the Gulf of Tehuantepec. Eleven Alexandrium species were identified, described, and illustrated using light microscopy, and occasionally scanning electron microscopy for certain species. Additionally, the genetic characterization of seven strains and four species, was performed, using sequences of the D1/D2 LSU rDNA and ITS regions. We identified the species (morphospecies): Alexandrium affine, A. gaarderae, A. globosum, A. leei, A. margalefii, A. minutum, A. monilatum, A. pseudogonyaulax, A. tamarense, A. tamiyavanichii, and A. tropicale. Of these, A. affine, A. leei, A. minutum, A. monilatum, A. pseudogonyaulax, A. tamarense and A. tamiyavanichii have been widely recognized as harmful algae. Alexandrium gaarderae, A. globosum and A. tropicale are new records for the Mexican Pacific. This is the first morphological documentation of A. pseudogonyaulax. Future studies of the genus might increase its species richness if more cultures are established and metabarcoding approach is used.
Removal efficiency of organic chloride from naphtha fraction using micro and nano-γ-Al2O3sintered adsorbents
Authors: Hosseingholilou Behnam , Arjang Samad , Saidi Majid 
Published: November 2023

AbstractThis research examines the removal efficiency of organic chloride (OC) compounds from the naphtha fraction of polluted crude oil (CO) using sintered micro and nano γ-Al2O3at a consistent temperature of 30 °C. The adsorbents were characterized through BET, SEM-EDS, and XRD analyses. When utilizing micro-adsorbents to eliminate OC components from naphtha fraction samples containing initial contaminant concentrations of 105 and 8.5 mg/L, the maximum removal efficiency reached only 28 % and 56 %, respectively. In contrast, the use of nano-based adsorbents resulted in significantly higher adsorption percentages, exceeding 45 % and 96 % for the same two samples, respectively. Equilibrium investigations revealed that the Freundlich isotherm model yielded a superior match for the adsorption equilibrium data for the nano-adsorbents case, while the Langmuir model accurately characterized the data for the micro-adsorbents. Kinetic data analysis indicated that the adsorption kinetics for nano-adsorbents followed the pseudo-second-order model, while the micro-adsorbents obeyed the intra-particle diffusion mechanism. Overall, these findings suggest that sintered γ-Al2O3nanoparticles (NPs) are more effective than microparticles (MPs) for the adsorptive removal of organic chlorides (OCs) from crude oil’s naphtha distillate.
A novel fabrication method of slippery lubricant-infused porous surface by thiol-ene click chemistry reaction for anti-fouling and anti-corrosion applications

Published: November 2023

Abstract
A novel and simple way for efficiently preparing stable and non-toxic slippery lubricant-infused porous surface (SLIPS) will expand its anti-fouling and anti-corrosion applications in marine environments. Herein, vinyl-terminated polydimethylsiloxane was covalently grafted on the surface of nano-SiO2 by a thiol-ene click chemistry reaction. After that, SLIPS was efficiently prepared at room temperature via the spraying method on various substrate surfaces. Surface wettability results showed that a water droplet (10 μL) can slip on the surface with an inclination of 10° and a stained water droplet can slip without stain during the slide process, which proved that SLIPS displayed excellent slippery performance. The existence of molecular-level slippery silicone oil film on the rough surface. Anti-fouling and anti-corrosion tests showed that the prepared SLIPS exhibited stable and excellent anti-fouling and anti-corrosion performance after immersion in Pseudoalteromonas sp. culture solution for 14 days. The SLIPS exhibited a value of more than 98% of bacterial attachment inhibition efficiency and a value of 99.9% of corrosion inhibition efficiency. This facile method provides guidance to fabricate SLIPS for its anti-fouling and anti-corrosion applications in marine environments.
Identification of in-sample positivity violations using regression trees: The PoRT algorithm
Authors: Danelian Gabriel , Foucher Yohann , Léger Maxime , Le Borgne Florent , Chatton Arthur 
Published: November 2023

AbstractBackgroundThe positivity assumption is crucial when drawing causal inferences from observational studies, but it is often overlooked in practice. A violation of positivity occurs when the sample contains a subgroup of individuals with an extreme relative frequency of experiencing one of the levels of exposure. To correctly estimate the causal effect, we must identify such individuals. For this purpose, we suggest a regression tree-based algorithm.DevelopmentBased on a succession of regression trees, the algorithm searches for combinations of covariate levels that result in subgroups of individuals with a low (un)exposed relative frequency.ApplicationWe applied the algorithm by reanalyzing four recently published medical studies. We identified the two violations of the positivity reported by the authors. In addition, we identified ten subgroups with a suspicion of violation.ConclusionsThe PoRT algorithm helps to detect in-sample positivity violations in causal studies. We implemented the algorithm in the R package RISCA to facilitate its use.
Has Chinese always been an analytic language? Effects of writing on language evolution
Authors: Zhang Liulin 
Published: November 2023

Abstract
Chinese is commonly believed to be an analytic language, but evidence from philological works and cross-linguistic comparisons clearly suggests that various morphological operations existed in Old Chinese. The loss of Chinese morphology can be explained by the ideographic nature of Chinese characters: the Chinese language has been evolving in a way that stabilizes the pronunciation of each character. The effects of writing systems on language evolution can be widely observed from world languages, while writing per se has been evolving along the path of phonetization driven mainly by borrowings instead of conscious linguistic analysis. In history, language never picked writing systems based on linguistic features; instead, writing systems affect the evolutionary paths of languages: single signs of a writing system stabilize the basic units of the language.
A corpus-based study of quoi in French native speech
Authors: Deng Delin , Wang Fenqi 
Published: November 2023

Abstract
Based on data drawn from two corpora collected in Orléans, France, in two waves (ESLO 1, 1968–1971; ESLO 2, 2008–) over a 40-year period, this paper investigated the use of quoi as a discourse marker (DM) in the speech of 234 French native speakers. Our results indicate that the DM quoi has increased in frequency in the more recent corpus. The distribution of its discursive functions has changed between the two corpora. Meanwhile, we also demonstrate that the DM quoi is mainly used in final position and this tendency continues to increase in ESLO 2. Regarding the relation between function and particle position, the planning function is the only function favored by medial position in ESLO 1, while in ESLO 2, the quantification function also becomes one of the favored functions in this position. We suggest that this might indicate potential competition for the same position. Meanwhile, we also point out that the benchmarking function is quasi-categorically used in final position in ESLO 2. The relation between functions and positions changes between the two corpora.
Lipin‐2 regulates the antiviral and anti‐inflammatory responses to interferon

Published: November 2023

AbstractInterferons (IFN) are crucial antiviral and immunomodulatory cytokines that exert their function through the regulation of a myriad of genes, many of which are not yet characterized. Here, we reveal that lipin‐2, a phosphatidic acid phosphatase whose mutations produce an autoinflammatory syndrome known as Majeed syndrome in humans, is regulated by IFN in a STAT‐1‐dependent manner. Lipin‐2 inhibits viral replication both in vitro and in vivo. Moreover, lipin‐2 also acts as a regulator of inflammation in a viral context by reducing the signaling through TLR3 and the generation of ROS and release of mtDNA that ultimately activate the NLRP3 inflammasome. Inhibitors of mtDNA release from mitochondria restrict IL‐1β production in lipin‐2‐deficient animals in a model of viral infection. Finally, analyses of databases from COVID‐19 patients show that LPIN2 expression levels negatively correlate with the severity of the disease. Overall, these results uncover novel regulatory mechanisms of the IFN response driven by lipin‐2 and open new perspectives for the future management of patients with LPIN2 mutations.
