Figure 24 in Three-dimensional geometry of a pterosaur wing skeleton, and its implications for aerial and terrestrial locomotion

Figure 24. Effects of pteroid depression. A, left lateral view of Anhanguera as in Fig. 23. B, as in (A), but with the left pteroid depressed by 30°. The camber is increased and the angle of attack, a, is reduced by this movement.

Figure 21. A, typical plots of pitching moment M against angle of attack a (measured with respect to the zero-lift angle of attack) for stable and unstable aircraft. Both aircraft are shown balancing at the same equilibrium angle of attack, at which point the pitching moment is zero. B, the effect of raising the elevators (1) on the longitudinal balance of a stable aircraft: the pitching moment is increased, as is the equilibrium angle of attack, so the aircraft pitches up (2) until equilibrium is restored. C, the effect of raising the elevators (1) on the longitudinal balance of an unstable aircraft: the pitching moment is increased, but the equilibrium angle of attack is reduced, so the aircraft now pitches up away from equilibrium (2).

Elements are oriented as in Fig. 7: distal syncarpal in lateral view and wing metacarpal in medial view. Scale bar: 50 mm.

Figure 22 in Three-dimensional geometry of a pterosaur wing skeleton, and its implications for aerial and terrestrial locomotion

Figure 22. Increasing the equilibrium angle of attack of an unstable aircraft can be brought about by decreasing the derivative dM/da, where M is the pitching moment and a is the angle of attack, by sweeping the wings back (A), or by decreasing the zero-lift pitching moment M0, by depressing the pteroids for example (B). These adjustments can theoretically be used in response to an unstable nose-up pitch (1), thus establishing a new equilibrium (2).

Data from: Detecting the effects of rapid tectonically-induced subsidence on Mayotte Island since 2018 on beach and reef morphology, and implications for coastal vulnerability to marine flooding

This dataset contains data from the monitoring morphological evolution of beaches and coral reefs in Mayotte island.  Mayotte, part of the coral reef-fringed Comoro archipelago in the SW Indian Ocean, experienced in 2018 and 2019 an intense seismic crisis. The repeated earthquake activity since May 2018 has been associated with deformation of the surface of Mayotte, resulting in land subsidence. The earlier 2006-2008 profiles were realized using a Leica TC 407® total station, and referenced to local IGN 50 benchmarks. The more recent 2019, 2020, and 2021 surveys were carried out using a GNSS differential Trimble R8S® system. Given the rapid subsidence that has affected Mayotte, the benchmarks used in this study, like others in Mayotte, need to be recalibrated by the IGN (French Institut Géographique National) and SHOM. This has still not yet been done, as the final outcome of the vertical island movements is still not clear.

Single-synapse analyses of Alzheimer's disease implicate pathologic tau, DJ1, CD47, and ApoE

Synaptic molecular characterization is limited for Alzheimer's disease (AD). Our newly invented mass cytometry-based method, Synaptometry by Time of Flight (SynTOF), was used to measure 38 antibody probes in approximately 17 million single-synapse events from human brains without pathologic change or with pure AD or Lewy body disease (LBD), non-human primates (NHP), and PS/APP mice. Synaptic molecular integrity in humans and NHP was similar. Although not detected in human synapses, Aβ was in PS/APP mice single-synapse events. Clustering and pattern identification of human synapses showed expected disease-specific differences, like increased hippocampal pathologic tau in AD and reduced caudate dopamine transporter in LBD, and revealed novel findings including increased hippocampal CD47 and lowered DJ1 in AD and higher ApoE in AD with dementia. Our results were independently supported by multiplex ion beam imaging of intact tissue. This highlights the higher depth and breadth of insight on neurodegenerative diseases obtainable through SynTOF.

Age-specific effects of deletions: Implications for ageing theories

Evolution of ageing requires mutations with late-life deleterious effects. Classic theories assume these mutations either have neutral (Mutation Accumulation) or beneficial (Antagonistic Pleiotropy) effects early in life, but it is also possible that they start out as mildly harmful and gradually become more deleterious with age. Despite a wealth of studies on the genetics of ageing, we still have a poor understanding of how common mutations with age-specific effects are and what ageing theory they support. To advance our knowledge on this topic we measure a set of genomic deletions for their heterozygous effects on juvenile performance, fecundity at three ages, and adult survival. Most deletions have age-specific effects, and these are commonly harmful late in life. Many of the deletions assayed here would thus contribute to ageing if present in a population. Taking only age-specific fecundity into account, some deletions support Antagonistic Pleiotropy, but the majority of them better fit a scenario where their negative effects on fecundity become progressively worse with age. Most deletions have a negative effect on juvenile performance, a fact which strengthens the conclusion that deletions primarily contribute to ageing through negative effects that amplify with age.

Reconciling the onshore/offshore stratigraphy of the Canning Basin and implications for petroleum prospectivity supplementary material

In this paper, figures 4 and 6 were made to a smaller scaler for improved visuals; however, this resulted in the extent of some units being left out of the figure. The supplementary material here includes the full extent of figures 4 and 6 so readers can identify where each unit was mapped in this study.

Post-weaning survival in kangaroos is high and constant until senescence: Implications for population dynamics

Large herbivores typically have consistently high prime-aged adult survival and lower, more variable, juvenile and senescent survival. Many kangaroo populations undergo greater fluctuations in density than other large herbivores, but age- and sex-specific survival of kangaroos and their response to environmental variation remain poorly estimated. We used long-term capture-mark-recapture data on 920 individuals to investigate the survival component of eastern grey kangaroo (Macropus giganteus) population dynamics. Forage availability and population density were monitored quarterly and included as predictors of survival in Bayesian Cormack-Jolly-Seber models. Annual survival probabilities were estimated for 5 age classes: 0 years (juveniles), 1–2 years (sub-adults), 3–6 years (prime-aged adults), 7–9 years (pre-senescent adults), and ≥10 years (senescent adults). Survival of juveniles varied widely during our 12-year study, ranging from 0.07–0.90 for females and 0.05–0.92 for males. Sub-adult survival was 0.80–0.93 for females and 0.75–0.85 for males, while that of prime-aged adults was ≥0.94 for females and ≥0.83 for males, despite large fluctuations in forage and density. The survival of pre-senescent adults spanned 0.86–0.93 for females and 0.60–0.86 for males. Senescent survival was variable, at 0.49–0.90 for females and 0.49–0.80 for males. Male survival was significantly lower than female survival in prime-aged and pre-senescent adults, but not in other age classes. Although most models supported by WAIC selection included one or a combination of environmental covariates, none of these individual covariates had a discernable effect on survival. Temporal variability in overall survival was mostly due to changes in survival of juvenile and senescent kangaroos. Kangaroo survival patterns are similar to those of ungulates, suggesting a strong role of sex-age structure on population dynamics.
