Deception is used by plants, animals, and humans to increase their fitness by persuading others of false beliefs that benefit the self, thereby creating evolutionary pressure to detect deception and avoid providing such unearned benefits to others. Self-deception can disrupt detection efforts by eliminating cognitive load and idiosyncratic deceptive cues, raising the possibility that persuading others of a false belief might be more achievable after first persuading oneself. If people self-deceive in service of their persuasive goals, self-deception should emerge whenever persuasion is paramount and hence should be evident in information sharing, generalized beliefs about the self, and intergroup relations. The mechanism, costs, and benefits of self-deceptive biases are explored from this evolutionary perspective.The water quality of the northern Caspian Sea has not been well-known, and its contamination can adversely affect the health of swimmers and seashore residents. The study sought to determine the contamination state of the Caspian Sea in Kazakhstan and quantify human health risks coming from the existing heavy metals concentration. The Caspian Sea was found to be "fairly to marginally" contaminated (24 less then CCME-WQI less then 64), with Cd influencing the index significantly. Concentrations of Cd and Pb increase over time (seasonal Kendall test, p-values = 2-4 %) in sites near oil fields and ports, suggesting the significant role of anthropogenic sources in causing diverse pollution events. Pb demonstrated the highest variability and number of outliers (4.3 % of all samples with coefficients of variation reaching up to 175 %). The principal component analysis further revealed that various discharges from oilfields and upstream transport could contribute to the contamination by heavy metals and their concentrations. Contamination is associated with up to 6 % cancer risk for adults. The long exposure duration of swimmers in water increases risks by up to 18 %, indicating the local population is at a higher risk. In conclusion, statistical tests and analysis indicate the presence of anthropogenic sources, and risk assessment reveals swimming can contribute to cancer risk.Laizhou Bay is plagued by many environmental problems (e.g., acidification and eutrophication) that are likely to increase in the coming decades along with social and demographic trends. We thus conducted 12 cruises from July 2019 to December 2021 in the Laizhou Bay to evaluate the potential influences of human activities on its eutrophication status. The results showed that the parameters of dissolved inorganic nitrogen (DIN) and oxygen (DO) exceeded the water quality standard in some cases during the past 3 years, suggesting DIN and DO were the crucial factors controlling water quality in the bay. Meanwhile, DIN was identified as a major pollutant in the region, and played an important role in driving the phytoplankton dynamics. Furthermore, with the increases in human-related nutrient inputs (especially DIN), the bay environment reached the mild eutrophication level and was probably at risk from excessive nutrient loads at present, further evidencing the ecosystem degradation.In coastal productive zones, phytoplankton activity may influence trace metal speciation and partitioning at short temporal scale. We coupled hourly in situ voltammetry quantification of the lead (Pb), cadmium (Cd), and copper (Cu) potentially bioavailable fractions, using an innovative submersible sensing probe (the TracMetal), to surface water sampling for the quantification of the targeted trace metals in the dissolved less then 0.2 μm and less then 0.02 μm fractions, suspended particles, and phytoplankton nets in the Gironde Estuary mouth. The in situ TracMetal monitoring reflected real-time dynamic Cd and Cu regeneration related to algal cells under post-bloom conditions as well as Pb remobilization due to photoreduction of colloids. The potentially bioavailable fraction consisted in 30, 30-50 and less then 10 % of the total dissolved fraction for Pb, Cd, and Cu, respectively, representing crucial ecotoxicological information. Metal bioconcentration factors using the dynamic fraction concentrations showed levels up to 107 for Cu in phytoplankton.
In Australia, sonographer's professional identity is traditionally 'caught' from clinical role models. A four-year undergraduate-postgraduate course introduced professional identity education, with simulated practice, to prepare novice sonographer students prior to clinical practice. Preclinical students learnt sonographer professional behaviour, and humanistic attributes, during simulation designed with volunteer peers as standardised patients, educator role-models, immediate feedback, self-reflection, and longitudinal multi-observer assessment. This paper reports on the transfer of learnt professional behaviour and humanistic attributes to clinical practice.
Professional behaviour evaluations completed by 94 clinical assessors described 174 students' professional behaviour and attributes one month into their initial clinical practice (2015-6). Student performance of each behaviour, and behavioural category, was quantitatively analysed by modelling binomial proportions with logistic regression.
Studentonographer professional identity, improved clinical outcomes and increased patient safety during the early stages of ultrasound education.
The incorporation of preclinical professional behaviour education with simulated practice into the core curriculum of sonographer courses is recommended for the formation of sonographer professional identity, improved clinical outcomes and increased patient safety during the early stages of ultrasound education.
Radiographer reporting is accepted practice in the UK. KP-457 inhibitor With a national shortage of radiographers and radiologists, artificial intelligence (AI) support in reporting may help minimise the backlog of unreported images. Modern AI is not well understood by human end-users. This may have ethical implications and impact human trust in these systems, due to over- and under-reliance. This study investigates the perceptions of reporting radiographers about AI, gathers information to explain how they may interact with AI in future and identifies features perceived as necessary for appropriate trust in these systems.
A Qualtrics® survey was designed and piloted by a team of UK AI expert radiographers. This paper reports the third part of the survey, open to reporting radiographers only.
86 responses were received. Respondents were confident in how an AI reached its decision (n=53, 62%). Less than a third of respondents would be confident communicating the AI decision to stakeholders. Affirmation from AI would improve confidence (n=49, 57%) and disagreement would make respondents seek a second opinion (n=60, 70%). There is a moderate trust level in AI for image interpretation. System performance data and AI visual explanations would increase trust.
Responses indicate that AI will have a strong impact on reporting radiographers' decision making in the future. Respondents are confident in how an AI makes decisions but less confident explaining this to others. Trust levels could be improved with explainable AI solutions.
This survey clarifies UK reporting radiographers' perceptions of AI, used for image interpretation, highlighting key issues with AI integration.

Fat-suppressed images are essential in clinical practice but are often affected by magnetic field inhomogeneity, resulting in poor image quality. We hypothesized that salt (99% sodium chloride [NaCl]) could be used as a magnetic field uniformity assist pad and verified whether salt pads improve magnetic field uniformity and the fat suppression effect in low-field magnetic resonance imaging (MRI) systems.
We conducted a small clinical study where coronal 2D fast spin-echo T2-weighted MRI with fat suppression was performed. The subjects were 10 healthy volunteers (six men and four women) with no surgical history, with a mean age of 20.5 years (range, 20-30 years). In the clinical study, we performed physical and visual evaluation by imaging a subject's knee with and without salt pads.
The results of the clinical study indicated that the use of salt pads improved the magnetic field uniformity, thus increasing the fat suppression effect.
Salt pads improved the homogeneity of the magnetic field and the fat suppression effect in low-field MRI systems.
The use of salt pads in low-field MRI systems could provide more accurate fat suppression images.

The purpose of this study is to investigate whether the mitochondrial DNA (mtDNA) content can reflect the state of mosaic embryos.
The study included 1669 blastocysts derived from 394 PGT-A cycles between January 2018 and December 2020, in which preimplantation genetic testing for aneuploidy was performed and mtDNA content was determined. The standard deviation (SD) of whole genomic sequencing data was calculated for quality control. mtDNA content was measured as the proportion of mtDNA to genomic DNA. 1558 blastocysts with SD values less than 4.0 and mtDNA values less than 0.4% were selected for statistical analysis.
The mtDNA content of the PGT mosaic group was significantly higher than that of the PGT normal group (P<0.001). Twenty-six mosaic embryos were transferred, and the results were as follows 2 out of 26 had undergone a spontaneous miscarriage, 15 were not pregnant, and 9 resulted in a live birth. There were significant differences in the mtDNA content between the miscarriage/non-pregnancy group and the live birth group (**P<0.01; ***P<0.001). There was no mosaic embryo with more than 0.157% mtDNA content found in the live birth group.
This study demonstrates that mtDNA analysis has the ability to identify mosaic embryos with high developmental potential. It can be a valuable supplementary index for the selection of mosaic embryos for transfer. Larger studies with a greater sample size will further our understanding of the relationships between metabolic activity and mosaicism.

This study included dyads comprised of adults entering treatment for alcohol use disorder and their Concerned Others (COs) to examine indicators of COs functioning (Al-Anon attendance and involvement, relationship stressors, use of approach coping and stigma) as predictors of patient outcomes (Alcoholics Anonymous (AA) attendance and involvement, abstinence and risk of substance use) over 12 months following adults' entry into AUD treatment.
Dyads (n=279) were assessed when patients entered treatment and at 3-, 6- and 12-month follow-ups. Data were collected through participants' self-report. Lagged generalized linear mixed models were used to examine associations between indicators of COs' functioning at baseline, 3- and 6-month follow-ups and patients' outcomes at 3-, 6- and 12-month follow-ups.
Patients reported less AA attendance and involvement and likelihood of maintaining abstinence from alcohol use over time. Findings from our multivariate analysis showed that any CO involvement in Al-Anon, relative to none, was associated with more patient AA attendance.
