No immediate or future extra costs of raising a virulent brood parasite chick

Parental care is an adaptive behavior increasing the survival of a young. Virulent brood parasites, like the common cuckoo Cuculus canorus, avoid the parental care and leave the care for their nestlings to hosts. Although raising a cuckoo is always costly because it kills host’s progeny, to date it is not known whether raising of a brood parasite itself represents any extra cost affecting host’s fitness, that is, a cost above the baseline levels of care that are expended on raising the host own young anyway. We quantified costs of rearing a cuckoo nestling in the most frequent host, the reed warbler Acrocephalus scirpaceus. We measured changes in the host physical (body mass) and physiological conditions (stress levels quantified via heterophils/lymphocytes ratio) within the 1 breeding attempt (immediate cost) and retrapped some of these adults in the next breeding season to estimate return rates as a measure of their survival (future cost). In contrast to universal claims in the literature, raising a cuckoo nestling did not entail any extra immediate or future costs for hosts above natural costs of care for own offsprings. This counterintuitive result might partly reconcile theoretical expectations in the hosts with surprisingly low levels of counter-defences, including the reed warbler. Unexpectedly low raising costs of parasitism may also help explain a long-term maintenance of some host–parasite systems.
Factors affecting the adoption of Sustainable Waste Management Behavior measures in Palm Oil Plantation in Sabah, Malaysia

Purpose: This study will examine how attitudes, subjective norms, and perceived behavioural control (PBC) affect sustainable waste management behaviour (SWMB) in Sabah, Malaysia's palm oil mills. Theoretical framework: This study has adopted the Theory of Planned Behaviour (TPB) that serves as the primary theory in this research, which utilized a conceptual framework. Design/ methodology/approach: This study employed a probability sampling where a series of questionnaires has been distributed to members of the upper management of 133 oil palm mills in Sabah were used to gather the data, which was then processed using Smart-PLS V4. Findings: According to the findings of this research, subjective norms and perceived behavioural control are important factors that contribute to SWMB adaptation in oil palm mills. The most significant association was found to be between subjective norms and SWMB. On the other hand, attitudes have been reported to have no substantial influence on environmentally responsible waste management behaviours. Research, Practical & Social Implications: To put it more succinctly, this study will give a framework for the regulation of palm oil waste in Malaysia through the establishment of a more effective legal and regulatory environment in this area.
Locoweed Seed in Soil: Density, Longevity, Germination, and Viability

Density of seed of three species of locoweed, salt milkvetch [Astragalus lentiginosus var. salinas (Howell) Barneby], Lambert locoweed (Oxytropis lambertii Pursh. # OXRLA), and white locoweed (O. sericea Nutt ex. T.&G. # OXRMA) in the soil was determined at four locations in New Mexico, Wyoming, and Utah. Seed density ranged from 50 to 2820/m2. Greater than 77% of the seed were viable as determined by tetrazolium tests. Longevity of white locoweed seed was determined by sewing seed into nylon mesh packets and returning them to the site of origin in northwestern Utah. Greater than 50% of seed buried 1 cm deep in the soil were still present after 6 yr, but only 33% of seed placed on the surface remained. Germinability of the buried seed was less than 5%, but an average of 14% of seed placed on the soil surface germinated each year. Viability of retrieved seed ranged from 89 to 99%.
Resolution of eleven reported and five novel Podaxis species based on ITS phylogeny, phylogenomics, morphology, ecology, and geographic distribution

The genus Podaxis was first described from India by Linnaeus in 1771, but several revisions of the genus have left the taxonomy unclear. Forty-four Podaxis species names and nine intraspecific varieties are currently accepted, but most fungarium specimens are labelled Podaxis pistillaris. Recent molecular analyses based on barcoding genes suggest that the genus comprises several species, but their status is largely unresolved. Here we obtained basidiospores and photographs from 166 fungarium specimens from around the world and generated a phylogeny based on rDNA internal transcribed spacer ITS1, 5.8S and ITS2 (ITS), and a phylogenomic analysis of 3 839 BUSCO genes from low-coverage genomes for a subset of the specimens. Combining phylogenetics, phylogenomics, morphology, ecology, and geographical distribution, spanning 250 years of collections, we propose that the genus includes at least 16 unambiguous species. Based on 10 type specimens (holotype, paratype, and syntype), four recorded species were confirmed, P. carcinomalis, P. deflersii, P. emerici, and P. farlowii. Comparing phylogenetic analysis with described species, including morphology, ecology, and distribution, we resurrected P. termitophilus and designated neotypes, epitypes, or lectotypes for five previously described species, P. aegyptiacus, P. africana, P. beringamensis, P. calyptratus, and P. perraldieri. Lastly, based on phylogenies and morphology of type material, we synonymized three reported species, P. algericus, P. arabicus, and P. rugospora with P. pistillaris, and described five new species that we named P. desolatus, P. inyoensis, P. mareebaensis, P. namaquensis, and P. namibensis.
Resolved and subgrid dynamics of Rayleigh–Bénard convection

In this work we present and demonstrate the reliability of a theoretical framework for the study of thermally driven turbulence. It consists of scale-by-scale budget equations for the second-order velocity and temperature structure functions and their limiting cases, represented by the turbulent kinetic energy and temperature variance budgets. This framework represents an extension of the classical Kolmogorov and Yaglom equations to inhomogeneous and anisotropic flows, and allows for a novel assessment of the turbulent processes occurring at different scales and locations in the fluid domain. Two relevant characteristic scales, $\ell _{c}^{u}$ for the velocity field and $\ell _{c}^{\unicode[STIX]{x1D703}}$ for the temperature field, are identified. These variables separate the space of scales into a quasi-homogeneous range, characterized by turbulent kinetic energy and temperature variance cascades towards dissipation, and an inhomogeneity-dominated range, where the production and the transport in physical space are important. This theoretical framework is then extended to the context of large-eddy simulation to quantify the effect of a low-pass filtering operation on both resolved and subgrid dynamics of turbulent Rayleigh–Bénard convection. It consists of single-point and scale-by-scale budget equations for the filtered velocity and temperature fields. To evaluate the effect of the filter length $\ell _{F}$ on the resolved and subgrid dynamics, the velocity and temperature fields obtained from a direct numerical simulation are split into filtered and residual components using a spectral cutoff filter. It is found that when $\ell _{F}$ is smaller than the minimum values of the cross-over scales given by $\ell _{c,min}^{\unicode[STIX]{x1D703}\ast }=\ell _{c,min}^{\unicode[STIX]{x1D703}}Nu/H=0.8$ , the resolved processes correspond to the exact ones, except for a depletion of viscous and thermal dissipations, and the only role of the subgrid scales is to drain turbulent kinetic energy and temperature variance to dissipate them. On the other hand, the resolved dynamics is much poorer in the near-wall region and the effects of the subgrid scales are more complex for filter lengths of the order of $\ell _{F}\approx 3\ell _{c,min}^{\unicode[STIX]{x1D703}}$ or larger. This study suggests that classic eddy-viscosity/diffusivity models employed in large-eddy simulation may suffer from some limitations for large filter lengths, and that alternative closures should be considered to account for the inhomogeneous processes at subgrid level. Moreover, the theoretical framework based on the filtered Kolmogorov and Yaglom equations may represent a valuable tool for future assessments of the subgrid-scale models.
Oldest shelly fossils from the Taconic Allochthon and late Early Cambrian sea-levels in eastern Laurentia

Continental slope facies in eastern New York have the most diverse small shelly faunas known in Laurentian late Early Cambrian strata. Diversity of a lower Elliptocephala asaphoides assemblage, the oldest body fauna in the Taconic allochthon, reflects turbidity current exhumation, transport, and deposition of phosphatized fossil hash in a proximal facies of the Browns Pond Formation. Phosphatization is linked to the first of two Olenellus Chron intervals with a thickened dysaerobic water mass on the slope. This interval of increased rate of sea-level rise corresponds to development of extensive carbonate belts and onlap of dark shales (e.g., Forteau and lower Kinzers formations) on the east Laurentian shelf. The assemblage includes two trilobites, archaeocyathan fragments, echinoderm debris, the first edrioasteriod from east Laurentia, and 26 small shelly fossil species. New taxa are Asperconella new genus and Stenotheca taconica new species (helcionellids); Mackinnonia obliqua new species (pararostroconch); Conotheca laurentiensis new species, Insolitotheca new genus, and Petasotheca minuta new genus and species (hyoliths); and Plinthokonion? psamminon new species (agglutinated problematicum).
Effect of Ownership Structure on Financial Performance: Evidence from Listed Airlines in Africa

Objective: This study empirically examines the impact of ownership structure on the financial performance of listed airlines in Africa. Design/Methods/Approach: The research utilized quantitative techniques to collect secondary data from listed airlines over ten years (2010-2019). Descriptive statistics and multiple regression were used for analysis. Findings: The results revealed that airlines with the majority of private domestic and private foreign ownership showed a significant positive effect on financial performance (ROA and ROE). In contrast, state ownership had an insignificant impact on airlines' financial performance. The study supports the property rights theory, emphasizing the importance of private ownership in airlines. Originality/Value: This study adds to the existing literature by providing evidence on how ownership structure influences financial performance in African airlines, contributing to aviation research. Practical/Policy Implication: The findings suggest that private and foreign investors should consider acquiring controlling airline stakes to enhance financial performance. Policymakers should aim to create flexible laws and regulations that attract domestic and foreign private investors to the aviation sector, potentially fostering improved management practices and policy developments.
How Frequent is Precipitation over the Contiguous United States? Perspectives from Ground-Based and Spaceborne Radars

AbstractHigh temporal and spatial resolution observations of precipitation occurrence from the NEXRAD-based Multi-Radar Multi-Sensor (MRMS) system are compared to matched observations from CloudSat for 3 years over the contiguous United States (CONUS). Across the CONUS, precipitation is generally reported more frequently by CloudSat (7.8%) than by MRMS (6.3%), with dependence on factors such as the NEXRAD beam height, the near-surface air temperature, and the surface elevation. There is general agreement between ground-based and satellite-derived precipitation events over flat surfaces, especially in widespread precipitation events and when the NEXRAD beam heights are low. Within 100 km of the nearest NEXRAD site, MRMS reports a precipitation frequency of 7.54% while CloudSat reports 7.38%. However, further inspection reveals offsetting biases between the products, where CloudSat reports more snow and MRMS reports more rain. The magnitudes of these discrepancies correlate with elevation, but they are obse.
Real-world data of triplet combination of pyrotinib, trastuzumab, and chemotherapy in HER2-positive metastatic breast cancer: a multicenter, retrospective study

Background: Pyrotinib, an irreversible pan-human epidermal growth (HER) inhibitor, has proven its antitumor efficacy as a second-line treatment for HER2-positive metastatic breast cancer (HER2+ MBC) when combined with capecitabine. However, real-world data concerning the pyrotinib, trastuzumab, and chemotherapy (PyroHC) combination remains scarce. Objectives: Our study is to report the treatment patterns, efficacy, and safety of the PyroHC combination in a real-world setting. Design: This study enrolled patients with HER2+ MBC from five institutions in China, treated with PyroHC between June 2017 and January 2023 (ClinicalTrials.gov, identifier: NCT05839288). Methods: We evaluated progression-free survival (PFS), objective response rate (ORR), toxicity profile, and utilized treatment regimens. Results: Of the 135 patients in our cohort, 91.9% had prior trastuzumab exposure and 52.2% underwent at least two systematic therapy lines before receiving PyroHC. The most prevalent chemotherapies paired with PyroH were capecitabine (36.3%). Patients receiving PyroHC achieved a median PFS of 8.67 months [95% confidence interval (CI): 6.84–10.51] and an ORR of 51.3% (95% CI: 42.1–61.5%). The first-line treatment with PyroHC led to a median PFS of 14.46 months (95% CI: 6.35–22.56). Patients with brain metastases showed a median PFS of 9.03 months (95% CI: 6.56–11.50), achieving an ORR of 52.17% (95% CI: 51.74–83.39). Longer previous trastuzumab (⩾6.37 months) or lapatinib (⩾10.05 months) therapies could indicate improved PFS, while prior pyrotinib exposure negatively influenced PFS. Notably, the most common grade 3/4 adverse events were diarrhea (37.8%), which were generally manageable. Conclusion: PyroHC shows promising efficacy and a satisfactory safety profile for treating HER2+ MBC, both as a first-line option and for heavily treated patients, including those with brain metastasis. Our findings suggest the duration and history of anti-HER2 therapy as potential predictors for PyroHC efficacy in advanced settings.
Retreat patterns and dynamics of the former Bear Island Trough Ice Stream

Covering one of the widest continental shelves in the world, the epicontinental Barents Sea is characterized by several shallow banks separated by troughs that open towards the Norwegian Sea in the west and the Arctic Ocean in the north (Fig. 1a). The bank areas have typical water depths of 100–200 m and the troughs 300–500 m. The most prominent cross-shelf trough, the Bear Island Trough (Bjornoyrenna), extends over 750 km from Storbanken (‘the large bank’ in Norwegian) in the NE to the shelf break in the SW (Fig. 1a). It is 150–200 km wide and spans water depths of 300–500 m. Ice sheet reconstructions over the last decades have recognized that a major ice sheet covered the whole Barents Sea during the Last Glacial Maximum (LGM; Mangerud et al. 1992; Svendsen et al. 2004). Large trough-mouth fans (TMFs; Vorren et al. 1989) appear as seaward-convex bulges in the bathymetry at the mouth of troughs that extend to the shelf break. The largest of these, the Bear Island Trough-Mouth Fan (Fig. 1a), contains up to 3–4 km of Plio-Pleistocene glacial sediments. The location of a major ice stream in the Bear Island Trough, draining the former Barents Sea and Fennoscandian ice sheets and delivering large amounts of sediments to the Bear Island TMF during the LGM (Fig. 1a), has been inferred from seafloor geomorphology and palaeo-ice-sheet geometry (Denton & Hughes 1981; Solheim et al. 1990; Ottesen et al. 2005; Andreassen et al. 2007), from studies of the fan itself (e.g. Vorren & Laberg 1997) and from borehole data (Saettem 1994). Two late glacial maxima have been inferred in the SW Barents Sea, one before 22 cal ka BP and one after 19 cal ka (Vorren & Laberg 1996). Fig. 1. Bathymetry, geomorphology, Last Glacial …
Reassessing Stimulation for EGS Reservoirs

Although the original attempts to stimulate hot dry rock or enhanced geothermal system (EGS) reservoirs employed conventional hydraulic fracturing methods, initial difficulty in obtaining sufficient connection between the stimulated zone and a targeted production well was experienced. Furthermore, the measurement of a cloud of microseismicity associated with the injections suggested shearing of natural fractures as an important process and led to development of stimulation methods that rely on shearinduced dilation to create reservoir permeability. Since this early change in approach, the process of stimulation applied to EGS reservoirs has continued to be founded on promoting shearing of natural fractures in the rock mass by injection of large volumes of water into long open-hole sections of the well at rates that limit the pressure to be at or below the fracture opening pressure. Shearing of natural fractures with the formation of wing fractures that then link between otherwise unconnected natural fractures provides a mechanism for development of directional conductive pathways when stimulation is carried out at or below fracture opening pressure. In particular, placing multiple fractures along a wellbore completed using a cemented casing string is expected to produce a better stimulation result compared to injection into a long openhole section. In addition, analysis of opening mode hydraulic fractures placed into hard, naturally fractured rock using pressures well above the minimum principal stress magnitude and then mapped in mineback experiments, show these fractures grew in the direction perpendicular to the minimum principal stress with offsets in their path developing at sites where the opening mode fracture interacts with and crosses natural fractures. This provides another mode of fracture growth that could be used to stimulate EGS reservoirs, provided cemented casing strings are used to complete the well.
Barotropic kinetic energy and enstrophy transfers in the atmosphere

The midlatitude atmosphere is characterized by turbulent eddies that act to produce a depth‐independent (barotropic) mean flow. Using the NCEP (National Centers for Environmental Prediction) Reanalysis 2 data, the latitudinal dependence of barotropic kinetic energy and enstrophy are investigated. Most of the barotropization takes place in the extratropics with a maximum value at midlatitudes, due to the latitudinal variations of the static stability, tropopause height, and sphericity of the planet. Barotropic advection transfers the eddy kinetic energy to the zonal mean flow and thus maintains the barotropic component of the eddy‐driven jet. The classic description of geostrophic turbulence exists only at high latitudes, where the quasi‐geostrophic flow is supercritical to baroclinic instability; the eddy‐eddy interactions carry both the barotropization of eddy kinetic energy upscale to the Rhines scale and the barotropization of eddy potential enstrophy downscale.
The recent warming trend in North Greenland

The Arctic is among the fastest warming regions on Earth, but it is also one with limited spatial coverage of multidecadal instrumental surface air temperature measurements. Consequently, atmospheric reanalyses are relatively unconstrained in this region, resulting in a large spread of estimated 30 year recent warming trends, which limits their use to investigate the mechanisms responsible for this trend. Here we present a surface temperature reconstruction over 1982–2011 at NEEM (North Greenland Eemian Ice Drilling Project, 51°W, 77°N), in North Greenland, based on the inversion of borehole temperature and inert gas isotope data. We find that NEEM has warmed by 2.7 ± 0.33°C over the past 30 years, from the long-term 1900–1970 average of −28.55 ± 0.29°C. The warming trend is principally caused by an increase in downward longwave heat flux. Atmospheric reanalyses underestimate this trend by 17%, underlining the need for more in situ observations to validate reanalyses.
A Variational LSTM Emulator of Sea Level Contribution From the Antarctic Ice Sheet

The Antarctic ice sheet (AIS) will be a dominant contributor to global mean sea level rise in the 21st century but remains a major source of uncertainty. The Ice Sheet Model Intercomparison for CMIP6 (ISMIP6) is an ensemble of continental‐scale models for studying the evolution of the AIS and projecting its future contribution to sea level. Due to their complexity and computational cost, ISMIP6 simulations are sparse and generated infrequently. Emulators are smaller‐scale models that approximate ISMs and enable experimentation and exploration into the drivers of sea level change. We introduce a neural network (NN) emulator to approximate the ISMIP6 ensemble, using a variational Long Short‐Term Memory (LSTM) with Monte Carlo dropout to quantify single‐projection uncertainty. The proposed NN emulator is compared to a Gaussian Process (GP) emulator on four criteria: accuracy of point estimates and predictive distributions of individual model projections, approximation of the ensemble projections, and model training time. The NN predicts more accurately on single projections, with a mean absolute error of 0.46 mm Sea Level Equivalent (SLE) versus 0.73 mm SLE for the GP, and has more accurate uncertainty estimates. The NN emulator also better approximates the ensemble distribution of ISMIP6 model projections, with a Kullback‐Leibler divergence of 18.26 versus 199.14 for GP at the projection year 2100. The NN enables more accurate experimentation with a reduced runtime, offering a new tool for understanding the important role of regional precipitation, ice sheet drainage systems, and interannual and longer timescale dynamics.
Decreased Concussion Incidence Following the Implementation of the Targeting Rules: An Updated Epidemiology of National Football League Concussions From 2017 to 2022

The incidence of concussions in football, and the ensuing media attention, has garnered scientific investigation, prompted technological advances in protective gear, and altered the rules of the game, including the National Football League’s (NFL) “Targeting” rule, which began in 2018, but the impact of these changes is unclear. This study aims to describe the epidemiology of concussions that occurred in five NFL seasons from the 2017-2018 season through the 2021-2022 season and characterize positional differences in rate and games missed. There was a significant decrease (p = 0.02) in total concussions between the 2017-2018 season (102 concussions) and the remaining four seasons (average of 73.80 concussions per year), accounting for a 38% decrease. Offensive and defensive units had decreased concussion rates and average games missed per concussion. Defensive backs (10.46 per 1,000 athlete exposures (AEs)) and tight ends (10.69 per 1,000 AEs) had the highest concussion rates, and the defensive line had the highest average games missed per concussion at 3.97. The introduction of the “Targeting” rule and other rule changes in the NFL in 2018 correlated with a decrease in total concussions per year, total games missed due to concussion, and average games missed per concussion. Offense and defense experienced similar reductions in concussion incidence and severity. Overall, the updated epidemiology of NFL concussions suggests that the incidence of concussions has decreased; however, players continue to experience concussions that require them to miss multiple games.
