Year-round acoustic presence of fin whales southwest of Svalbard suggests mixed-use habitat for feeding and breeding
Abstract Multiple lines of evidence indicate a northward expansion and year-round presence of fin whales especially around Svalbard, an area where highly variable Atlantic Water intrusion is changing the trophic community. Because fin whales are now documented in the high Arctic (≥ 80°N), we hypothesized that this would also increase their presence in lower latitude Arctic regions. We used one year of passive acoustic data collected on a mooring deployed on the continental slope southwest of Svalbard to assess the temporal acoustic presence of fin whales and the relationship with environmental data. Acoustic detections and call diversity were greatest in fall and spring and lowest in summer. The 20 Hz calls were present from July to April and the 130 Hz calls were present from August to April. Both calls peaked in September with smaller, secondary peaks in March. Downsweeps were bimodally present between July and October and between February and June. Linear models indicated more calls when krill and copepod numbers were high and sea ice extent and amphipod numbers were low. A year-round acoustic presence of a potential resident subpopulation of fin whales suggests the region is a mixed-use habitat for foraging and reproductive-related activities.

Diagnostic accuracy of Transmitted-light plethysmography for the assessment of pulpal circulation in traumatized young permanent incisors
Abstract Transmitted light plethysmography (TLP) is a noninvasive, objective optical method used to assess dental pulp circulation and evaluate pulp vitality. This study aimed to develop a quantitative diagnostic approach for TLP and assess its accuracy through cross-correlation analysis of plethysmographic signals obtained from both the tooth and the finger. A total of 131 maxillary incisors from 97 pediatric patients (aged 6–17 years) were categorized into three groups: nontraumatized teeth, traumatized vital teeth, and traumatized nonvital teeth. Standard diagnostic procedures, including assessments for discoloration, percussion sensitivity, periapical translucency, and electric pulp testing (EPT), were performed alongside TLP evaluation, 3 to 18 months following dental trauma. Tooth plethysmograms were acquired using a 525 nm light-emitting diode directed through the examined teeth, while simultaneous finger plethysmograms were recorded as reference signals. Cross-correlation coefficients (R-values; 0 < R < 1) were calculated between the tooth and finger signals for each tooth, and diagnostic cutoff thresholds were determined using receiver operating characteristic (ROC) curve analysis based on the maximum Youden index. Statistically significant differences in R-values were observed among the three groups. The optimal diagnostic cutoff was identified as 0.40 (95% confidence interval: 0.38–0.45), at which TLP demonstrated a sensitivity of 0.94 and a specificity of 0.88, outperforming EPT. Logistic regression analysis incorporating all pulp testing methods revealed a significant association with pulp vitality status. Furthermore, the area under the ROC curve (AUC) for TLP combined with standard tests was significantly greater than that of any individual model. These results indicate that TLP offers improved diagnostic precision for identifying nonvital pulp and may serve as a valuable adjunct to conventional pulp vitality assessments.
