This article addresses the proposition that the lower Lahontan drainage basin (LLDB) is “unique” within the Intermountain West in terms of the use of caves and rockshelters as burial locations, and that such burials are “rare” elsewhere (Thomas et al. 2025). We compare archaeologically known cave burials in the Bonneville basin (BB), ranging in age from approximately 10,700 to approximately 1000 cal BP, to those in the LLDB. There are 18 such sites in the BB and an additional five in the upper Lahontan basin within the foraging range of late Holocene BB farmer-foragers. Although this number is roughly half of that in the LLDB, such sites are not “rare” or even uncommon in the BB. The difference in numbers may be attributed more to differences in population sizes in the two basins than to differences in burial practices. After about 5000 cal BP, many caves and rockshelters containing burials in the LLDB were occupied residentially, diurnally, or while storing and retrieving cached material. Given that Thomas and colleagues (2025:246) indicate the Northern Paiute tended to avoid such caves, it is likely that it was the ancestors of other groups who lived in them. Ethnographic and archaeological evidence suggests that at least some of these caves were occupied by the ancestral Washoe, whose historic territory extended into the LLDB, and possibly by related tribes who now reside exclusively in California.
The memoir of Shadrack Byfield, an English weaver and war amputee, occupies a privileged place in the historiography and public memory of the Anglo‑American War of 1812. Yet relatively little is known about the author of this rare rank-and-file account. Drawing on extensive archival research and a newly discovered second autobiography, this article challenges the familiar image of Byfield as a plainspoken exemplar of military stoicism. It reveals how war in North America transformed the former private soldier both physically and psychologically. Examining Byfield’s return to civilian life, the article highlights his tenacious pursuit of veterans’ benefits, his cultivation of influential patrons, and his invention of a prosthetic device to enable a resumption of weaving work. It also traces the ex‑serviceman’s path to publication and explores his shifting self‑presentation in print—first as a dutiful soldier and later as a redeemed sinner. Integrating scholarship on disability, memoirs, military welfare, and the history of emotions, the article argues that Byfield’s exceptionally well‑documented life offers a window into the wider experiences of Britain’s homecoming soldiers after the Napoleonic Wars.
Wetlands are critical ecosystems for many species of conservation concern, including migratory birds. These species face resource depletion and unpredictability in the context of global change and are expected to adjust their space use accordingly. Understanding how waterbirds use space and identifying their foraging needs are essential for guiding conservation efforts. Here, we present preliminary results on the fine-scale space use of a wetland flagship species, the Whiskered Tern Chlidonias hybrida, in La Brenne, a historical French breeding stronghold. The species is listed as ‘Vulnerable’ in France and breeds in only a few large wetlands. For the first time, we equipped four adult terns with miniature GPS tracking devices, providing unique, high-resolution data on their daily movements throughout the breeding season (i.e. pre-incubation, incubation, rearing, and post-breeding). Our results showed that most daily foraging trips did not exceed 2–3 km, resulting in relatively small home ranges (ranging from 2.00 km2 to 14.95 km2). Values were higher during the post-breeding period (up to 8 km from the nest and home range size up to 74.45 km2). Furthermore, we found that Whiskered Terns remained faithful to their foraging areas throughout the season and preferentially foraged in ponds – especially those near their colony – compared with other potential foraging habitats. On average, 91% of foraging positions occurred in ponds and 9% in grasslands. We also provide practical details on bird capture and device attachment methods. Finally, this pioneering bio-logging study offers promising prospects for future research on the movement ecology of Whiskered Terns, which could be invaluable for their conservation.
Amorphous materials transition from solid-like to liquid-like behaviour (yield) under large stresses. Their constituent elements are caged in metastable configurations due to their neighbours. Microscale interactions between these elements lead to a large energy barrier to break the cages and trigger a plastic rearrangement. Thermal fluctuations can alter the yielding point as the elements hop to new configurations in anticipation. This work bridges the gap between molecular-scale physics and bulk rheology in thermal amorphous materials by connecting a classical density functional theory to a thermally activated elastoplastic model (EPM). We use a model system of solvent-free polymer-grafted nanoparticles which show rheological characteristics similar to those of soft glassy materials. We formulate the evolution of the free energy in a deforming array of polymer-grafted nanoparticles to obtain the energy landscape as an input to our EPM. We examine how the apparent yield stress depends on the shape of the energy landscape, thermal fluctuations and the rate of deformation. Our general scaling analyses reveal different regimes of structural relaxation governed by the applied shear rate and the inherent time scale for thermal hops. The complex interplay between mechanical loading and thermal fluctuations is further characterized by performing a variety of shear tests with different deformation history. The proposed framework provides an understanding of the yielding transition by integrating across a vast range of length and time scales.
Reservoir construction causes marked changes in hydrological, physical and chemical conditions, with rapid effects on aquatic communities. The initial filling phase, characterised by abrupt changes over days to weeks and the onset of vertical stratification, is particularly critical, yet its effects on planktonic ciliate communities remain poorly understood. Here, we combined high-frequency sampling with a two-strata design (surface and bottom) to investigate how the initial filling, and consequent vertical stratification, of a tropical reservoir affect the density, biomass and taxonomic groups composition of the planktonic ciliates community. We observed pronounced temporal and spatial changes, with physicochemical differences between strata and filling phases. We observed that the ciliate community responded to these changes with consistently higher density and biomass at the surface and in the middle of the filling period. Linear mixed-effects and generalised additive models supported our findings, with significant temporal variation in all attributes, with trajectories over the filling period characterised by an initial increase followed by a decline, and by marked shifts among ciliate groups that indicate a clear successional pattern. Our results suggest that the surface strata of the reservoir work as a dynamic and productive environment, whereas the bottom strata remain limiting for ciliate development, mainly due to lower oxygen concentrations. By providing one of the few high-resolution assessments of planktonic ciliates during reservoir filling, integrating vertical structure, temporal dynamics and taxonomic succession, this study extends the trophic-surge perspective to microbial consumers and highlights the value of ciliates as bioindicators during dam construction and early reservoir operation.
Ventricular perforation is a serious complication of percutaneous myocardial biopsy. Accurate orientation of the biopsy forceps toward the ventricular septum under fluoroscopy is essential to minimise this risk. However, in paediatric patients, variations in ventricular septal orientation complicate proper forceps alignment. No previous studies have addressed this variability in children.
Methods:
We retrospectively analysed paediatric patients who underwent myocardial biopsy between January 2019 and June 2023. The angle of the ventricular septum relative to the sagittal plane was measured using cardiac CT. Biopsies were performed under fluoroscopic guidance, with individualised angles adjusted to align with the septum. Fluoroscopic images were used to calculate the angle between the biopsy forceps and the septum and the combined angle relative to the sagittal plane.
Results:
Sixteen patients underwent a total of 85 biopsies; only the first biopsy per patient was included in the analysis. The mean angle of the septum was 54.3° (range: 30.0–75.0°), the mean angle between forceps and septum was 21.3° (range: 3.5–53.4°), and the combined angle relative to the sagittal plane was 75.6° (range: 45.0–115.7°). No cases of ventricular perforation were observed.
Conclusion:
Ventricular septal orientation varies significantly in paediatric patients. Individualised adjustment of fluoroscopic angles based on pre-procedural CT measurements allows accurate positioning of biopsy forceps and may reduce the risk of severe complications.
This paper investigates the nonlinear dynamics of horizontal shear instability in an incompressible, stratified and rotating fluid in the non-traditional $f$-plane, i.e. with the full Coriolis acceleration, using direct numerical simulations. The study is restricted to two-dimensional horizontal perturbations. It is therefore independent of the vertical (traditional) Coriolis parameter. However, the flow has three velocity components due to the horizontal (non-traditional) Coriolis parameter. Three different scenarios of nonlinear evolution of the shear instability are identified, depending on the non-dimensional Brunt–Väisälä frequency $N$ and the non-dimensional non-traditional Coriolis parameter $\tilde {f}$ (non-dimensionalised by the maximum shear), in the range $\tilde {f}\lt N$ for fixed Reynolds and Schmidt numbers $ \textit{Re}=2000$, $ \textit{Sc}=1$. When the stratification is strong $N\gg 1$, the shear instability generates stable Kelvin–Helmholtz billows like in the traditional limit $\tilde {f}=0$. Furthermore, when $N\gg 1$, the governing equations for any $\tilde {f}$ can be transformed into those for $\tilde {f}=0$. This enables us to directly predict the characteristics of the flow depending on $\tilde {f}$ and $N$. When $N$ is around unity and $\tilde {f}$ is above a threshold, the primary Kelvin–Helmholtz vortex is destabilised by secondary instabilities but it remains coherent. For weaker stratification, $N\leqslant 0.5$ and $\tilde {f}$ large enough, secondary instabilities develop vigorously and destroy the primary vortex into small-scales turbulence. Concomitantly, the enstrophy rises to high values by stretching/tilting as in fully three-dimensional flows. A local analysis of the flow prior to the onset of secondary instabilities reveals that the Fjørtoft necessary condition for instability is satisfied, suggesting that they correspond to shear instabilities.
Infants with single ventricle physiology are at increased risk of undernutrition, which can contribute to adverse outcomes. This is a retrospective case series examining factors associated with undernutrition in patients with single ventricle physiology at one year of age. It includes 56 infants from a single institution who underwent single ventricle palliation between 2003 and 2023. Undernutrition was defined as a weight-for-length z-score below -1, based on World Health Organization normative data. Independent variables included surgical interventions, cardiorespiratory factors, and nutritional interventions. Associations between these variables and nutritional status were assessed using Fisher’s exact test. At one year, a total of nine infants (16%) were undernourished. Undernutrition rates significantly declined after 2013 (p = 0.02), demonstrating improvements in nutritional outcomes over our study period. Those who used supplemental oxygen or pulmonary medications were undernourished at lower rates, though this difference was not statistically significant. While the number of undernourished patients in the cohort may have limited the study’s power, our findings suggest that early respiratory interventions may provide nutritional benefits in infants with single ventricle physiology.
This article traces how and why the ‘competition’ of marriage culminated in the rise of the matrimonial advertisement across early twentieth-century India. It examines how the matrimonial, as a systematized textual schema, became a constitutive component of a reforming marriage market and integral to how the gendered body was imagined within transforming familial norms. The article draws on the extensive scholarship on labour and marriage in colonial Bengal to argue for the development of an ‘All-India’ middle-class marital marketplace as new forms of networking and work emerged. It does this by undertaking a cross-regional comparative analysis of matrimonials between 1915 and 1950 across urban India—alongside memoirs, colonial ethnographies, and periodicals—to extrapolate strategies of status-making and explore how discourses on conjugality ceded into legislative debates around customary law and property. The article begins by considering the placement and composition of matrimonials before delving into how matches were assessed, arguing that they expressed shifting marital norms, conjugal capital, and caste consolidation which led to the commodification of an expansive marital marketplace. It then examines debates around monetary marriage exchanges (like dowry) as a form of capital accumulation, disentangling how requests were articulated within the matrimonial advertisement through the complex textual grammars of signalling wealth.
Late complications following surgical repair of aortic coarctation may include hypertension, aortic valve disease, coronary artery disease, aneurysm formation, and recoarctation. However, preprocedural aneurysmal dilatation is rarely reported.
Case Presentation:
We report the case of an 11-year-old male with severe aortic coarctation and a giant aneurysm identified prior to any surgical or interventional treatment. Takayasu’s arteritis was ruled out, and the patient underwent successful percutaneous placement of a covered stent. Post-procedure, he showed no residual gradient or aneurysmal lesion.
Conclusion:
This case highlights a rare presentation of aneurysmal dilatation occurring prior to any intervention for aortic coarctation and supports the efficacy of covered stent placement as a safe and effective therapeutic option.
This study examines the relationship between microfinance and poverty alleviation, considering the moderating effect of both digital and traditional financial knowledge, as well as of social capital. The data sample comprises survey responses from 500 clients of conventional and Islamic microfinance institutions in Bhakkar, one of Pakistan’s most dynamic microfinance districts. The empirical results, obtained via structural equation modeling, show that digital financial knowledge positively moderates the relationship between microfinance effectiveness and poverty alleviation. A similar result is found for the moderating role of social capital when traditional financial knowledge is included in the model. However, this is not the case when digital financial knowledge is included in the model. These findings emphasize the importance of promoting both financial literacy and digital skills to maximize the positive impact of microfinance on poverty reduction.
