Effects of Continuous Non-Invasive Blood Pressure Monitoring on Intraoperative Hemodynamics and Postoperative Myocardial Injury in Craniotomy: Comparison Between Groups Based on Self-Control and Propensity Score Matching

Objective: To explore the effect of continuous non-invasive blood pressure monitoring on intraoperative hemodynamics and postoperative myocardial injury in craniotomy. Methods: 120 cases of elective craniotomy were divided into the self-control group (continuous non-invasive blood pressure monitoring and intermittent cuff non-invasive blood pressure monitoring, CNAP group) and propensity score matching group (only intermittent cuff non-invasive blood pressure measurement in previous craniotomy, PSM group); Goal-directed hemodynamic management in CNAP group included heart rate (HR), blood pressure (BP), stroke volume (SV), stroke variability (SVV), and systemic vascular resistance index (SVRI). The main index is to compare the troponin level within 72 hours after operation between the CNAP group and the PSM group; The secondary indicators are the comparison of the hemodynamic conditions between the CNAP group and the PSM at 10 specific time points. Results: The incidence of postoperative myocardial injury in the CNAP group was significantly lower than that in the PSM group (12% vs. 30%, P = 0.01); in the CNAP group hypotensive episodes (6 vs. 3, P = 0.01), positive balance of fluid therapy (700 vs. 500 mL, P < 0.001), more use of vasoactive drugs (29 vs. 18, P = 0.04), more stable hemodynamics medical status (P = 0.03) were recorded. Conclusion: The hemodynamic management strategy based on continuous non-invasive blood pressure monitoring can reduce the incidence of myocardial injury after elective craniotomy and maintain a more stable hemodynamic state.
Grass pollen surface ornamentation is diverse across the phylogeny: Evidence from northern South America and the global literature

The grasses are one of the most diverse plant families on Earth. However, their classification and evolutionary history are obscured by their pollen stenopalynous (similar) morphology. A combination of high‐resolution imaging of pollen surface ornamentation and computational analysis has previously been proposed as a promising tool to classify grass taxonomic boundaries. In this study, we test this hypothesis by studying Poaceae pollen across the phylogeny from plants collected in northern South America and also from published literature across the globe. We assessed if morphotypes that we establish using descriptive terminology are supported by computational analysis, if they vary along six (a)biotic variables and vary across the phylogeny. Based on this analysis, we constructed a reference framework for pollen surface ornamentation morphotypes. Our results showed that there is a wide variation of grass pollen surface ornamentation. We identified nine new and confirmed six known morphotypes, establishing a data set for 223 species (243 individual plant specimens) that represent 11 subfamilies. Computational analysis showed that our morphotypes are well‐supported by two quantitative features of pollen sculptural elements (size and density). The specific data set and mapping of the phylogeny confirmed that pollen morphological sculpture is unrelated to (a)biotic variables and is diverse across the phylogeny.
Anti‐Siglec‐15 Antibody Prevents Marked Bone Loss after Acute Spinal Cord Injury‐Induced Immobilization in Rats

Rapid and extensive sublesional bone loss after spinal cord injury (SCI) is a difficult medical problem that has been refractory to available interventions except the antiresorptive agent denosumab (DMAB). While DMAB has shown some efficacy in inhibiting bone loss, its concurrent inhibition of bone formation limits its use. Sialic acid‐binding immunoglobulin‐like lectin (Siglec)‐15 is expressed on the cell surface of mature osteoclasts. Anti‐Siglec‐15 antibody (Ab) has been shown to inhibit osteoclast maturation and bone resorption while maintaining osteoblast activity, which is distinct from current antiresorptive agents that inhibit the activity of both osteoclasts and osteoblasts. The goal of the present study is to test a Siglec‐15 Ab (NP159) as a new treatment option to prevent bone loss in an acute SCI model. To this end, 4‐month‐old male Wistar rats underwent complete spinal cord transection and were treated with either vehicle or NP159 at 20 mg/kg once every 2 weeks for 8 weeks. SCI results in significant decreases in bone mineral density (BMD, −18.7%), trabecular bone volume (−43.1%), trabecular connectivity (−59.7%), and bone stiffness (−76.3%) at the distal femur. Treatment with NP159 almost completely prevents the aforementioned deterioration of bone after SCI. Blood and histomorphometric analyses revealed that NP159 is able to greatly inhibit bone resorption while maintaining bone formation after acute SCI. In ex vivo cultures of bone marrow cells, NP159 reduces osteoclastogenesis while increasing osteoblastogenesis. In summary, treatment with NP159 almost fully prevents sublesional loss of BMD and metaphysis trabecular bone volume and preserves bone strength in a rat model of acute SCI. Because of its unique ability to reduce osteoclastogenesis and bone resorption while promoting osteoblastogenesis to maintain bone formation, Siglec‐15 Ab may hold greater promise as a therapeutic agent, compared with the exclusively antiresorptive or anabolic agents that are currently used, in mitigating the striking bone loss that occurs after SCI or other conditions associated with severe immobilization. © 2023 The Authors.

Physiotherapists’ Ethical Climate and Work Satisfaction: A STROBE-Compliant Cross-Sectional Study

(1) Background: This study aimed to examine the relationship between Spanish physical therapists’ perceptions of the ethical climate, their moral sensitivity (awareness of ethical issues), and job satisfaction. (2) Methods: the study analyzed descriptive correlational data on 104 physical therapists from three Spanish metropolitan hospitals. Respondents completed a demographic data form, an ethical climate questionnaire, a job satisfaction survey, and a moral sensitivity scale. This study complies with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. (3) Results: With a mean score of 4.2, physical therapists are typically content with their jobs. The mean scores for the moral sensitivity and ethical climate questionnaires are high, at 40.1 (SD 6.3) and 96.8 (SD 17.1), respectively. There is a significant positive correlation between job satisfaction and ethical climate (r between 0.59 and 0.79) but only a weak correlation between job satisfaction and moral sensibility (r between 0 and 0.32 for the three aspects measured). (4) Conclusions: Generally speaking, physical therapists reported that they had high job satisfaction, a positive workplace environment, and excellent management support. Despite a weak relationship with moral sensibility, there is a strong association between ethical behavior, hospital organization, and higher levels of job satisfaction. It is important to encourage the development of moral sensibilities to boost psychological well-being and therapeutic decision-making.
The Relationship between the Interannual Variation of the North Indian Ocean SST Induced by Surface Wind and ENSO during Boreal Summer

Abstract The relationship between the interannual variation of the surface wind in the north Indian Ocean (0°–30°N, 30°–100°E) and El Nino–Southern Oscillation (ENSO) during boreal summer is investigated. The association of the surface wind with the sea surface temperature (SST) in the north Indian Ocean is evaluated. The NCEP–NCAR reanalysis, NOAA outgoing longwave radiation (OLR), and Reynolds SST data are used. The June–August mean of the surface wind anomaly over the north Indian Ocean is decomposed by EOF analysis, and two dominant modes are extracted. The first (second) mode shows the corresponding variation with the ENSO events maturing in the subsequent (previous) winter. The first mode has a large amplitude during the 1990s, while the amplitude of the second mode is large mainly during the 1980s. Such contrast of the amplitude of the two modes results in the temporal change of the surface wind–ENSO relationships between the two decades. The temporal characteristics of the first and second modes a.
Linking vegetation response to seasonal precipitation in the Okavango–Kwando–Zambezi catchment of southern Africa

Understanding how intra-annual precipitation variability affects seasonal vegetation dynamics is critical for assessing the potential impacts of climate variability on vegetation structure and composition. This is important in semi-arid and arid ecosystems of southern Africa, where water is a limiting resource and timing of seasonal rainfall combined with the water storage capacity of different plant vegetation types affects remotely measured phenological cycles. Various lags and leads of savanna vegetation response to rainfall have been identified using remotely sensed data, but little attention has been given to vegetation greenness leading into the dry season. Vegetation production at the onset of the dry season interacts with the availability of water resources affecting fire dynamics, forage materials for wildlife and wildlife movement throughout the dry season. This is important for southern Africa as large proportions of the human population and economy are dependent on wildlife tourism. This study investigates the response of the end of the wet season vegetation production, as measured by Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI) greenness, to the different months of wet season rainfall for different savanna vegetation types in a regional catchment of southern Africa. We estimated monthly precipitation using Tropical Rainfall Monitoring Mission 3B43 data and used MODIS 13A1 NDVI at a monthly time step for the years 2000–2009. Our model estimated greenness at the beginning of the dry season from the prior rainy season (October–April) precipitation using geographically weighted regression (GWR). The results show intra-annual wet season rainfall accounts for significant amounts of April NDVI variation. Overall intra-annual rainfall has a stronger effect for areas with greater proportions of grassland and dry, deciduous woodlands than for wetter, evergreen woodlands. These findings support previous research by highlighting the stronger association of grassland and open canopy woodlands to the end of the wet season monthly rainfall. This relationship is important for understanding seasonal precipitation effects on different savanna vegetation covers.
Cometary capture and the nature of the impactors

Abstract The inclination-averaged capture probability from nearly parabolic orbits to Halley-type orbits with periods P < 200 years and q < 1.5 AU is 0.0128 for an isotropic long-period source flux with perihelion distances q < 4 AU. The observed near-parabolic flux brighter than visual absolute magnitude H10 = 7 is approximately 0.2 comets AU−1 a−1, and the dynamical lifetime of the captured Halley-type comets is on the order of 0.3 Ma. The predicted steady-state number of such comets is thus about 3000, many times more than the number of observed Halley-type comets. Provided that long-period comets do not totally disintegrate during the capture process (e.g. into streams of small bodies such as cometary meteoroids and dust), this indicates that there should be a large population of undiscovered Halley-type ‘asteroids’ in the inner Solar System. The predicted number of dark Halley-type objects is sufficient to produce a terrestrial cratering rate comparable with that from observed near-Earth asteroids, and hence could explain the reported Galactic signal seen in the geological and biological records. The assessment of the terrestrial impact hazard should consider the possibility that a significant number of dark Halley-type objects may exist.
TECTONIC AND SEDIMENT SUPPLY CONTROL OF DEEP RIFT LAKE TURBIDITE SYSTEMS :LAKE BAIKAL, RUSSIA

Tectonically influenced half-graben morphology controls the amount and type of sediment supply and consequent type of late Quaternary turbidite systems developed in the active rift basins of Lake Baikal, Russia. Steep border fault slopes (footwall) on the northwest sides of half-graben basins provide a limited supply of coarser grained clastic material to multiple small fan deltas. These multiple sediment sources in turn laterally feed small ( 65 km) axially fed elongate mud-rich fans sourced by regional exterior drainage of the Selenga River that supplies large quantities of silt. Basin plain turbidites in the center of the linear basins and axial channels that are controlled by rift-parallel faults are fed from, and interfinger with, aprons and fans. The predictability of the turbidite systems in Lake Baikal provides the best example yet studied of how tectonics and sediment supply interact to control the development of a wide variety of coeval turbidite systems on a single basin floor.
Spatial variations of ocean wave directional spectra from the Seasat synthetic aperture radar

Seasat synthetic aperture radar ocean wave spectra for a 900-km pass are analyzed and interpreted in the context of both their probable generation sources and their surface current and bathymetric modifiers. Systematic vector wavenumber variations of several times the standard error of determination (∼1.5 % in magnitude and 0.9° in direction) occur along the entire 900-km pass. The large-scale spatial variation of a 200-m swell system can be accurately accounted for as a result of dispersion from a distant storm. The more local variations are qualitatively well correlated in position with known currents and bathymetry but show systematic biases that appear partly due to an environmentally dependent instrument transfer function in the regions of high current and highest sea state. There is also substantial evidence that a large angular deviation in the center of the pass is the result of a mesoscale eddy just to the east.
Resistivity imaging survey of the Roman barrows at Bartlow, Cambridgeshire, UK

Resistivity imaging was carried out on four large Roman barrows at Bartlow in Cambridgeshire. The geophysical survey formed part of a wider research project designed to record and assess the landscape context of the largest surviving Roman burial mounds in Britain. The barrows today range in height from 6.6 m to 13.2 m and their steep profile posed particular practical and modelling challenges. Data were obtained using a Campus Geopulse resistance meter with up to 50 electrodes spaced at 1 m intervals and lines up to 76 m long. A total of 24 lines was obtained. Topographic corrections were applied to the pseudosections, which were inverted using Res2Dinv and Res3Dinv. Resistivity imaging was particularly successful in identifying evidence for the antiquarian explorations of the site. Central collapse features or in‐filled tunnels image as high resistance features in all barrows and in one (Barrow IV) there is also a low resistance feature in the approximate position of a known antiquarian tunnel. Barrow VI had a thick covering of high‐resistivity that may relate to nineteenth century landscaping and reconstruction of this monument. Resistivity imaging also revealed possible evidence for ancient revetments in all four large barrows. Copyright © 2006 John Wiley & Sons, Ltd.
A comparison of thermal infrared and ultraviolet retrievals of SO2 in the cloud produced by the 2003 Al‐Mishraq State sulfur plant fire

The detection of SO2 plumes by space‐based sensors has been demonstrated in the UV and TIR. However, the relationship between these retrieval techniques is poorly constrained. In this paper we compare near‐coincidental EP TOMS and MODIS data of a near‐pure SO2 plume from the Al‐Mishraq State sulfur plant fire on 29 June 2003. We resampled the MODIS data to the spatial resolution of EP TOMS in order to compare the two SO2 retrievals at the pixel scale. EP TOMS and MODIS return SO2 total tonnages of 103 and 118 kt, respectively. Overall, the agreement between the techniques on a pixel scale ranges between 10% to greater than 90% with no discernible spatial pattern. The variable agreement between the two retrievals is likely the result of differences in spatial resolution, presence of sulfates, and variations in plume height with distance from the fire.
Ecological and Social Aspects of Transhumant Herding in Bhutan

Abstract Little is understood about the role of transhumance in subsistence economy and the interactions between cattle, forest, and pasture-land in the Himalaya. We examined herding practices and the effects of grazing on forest ecology and grassland, using rapid rural appraisal techniques with transhumant herders in Haa and Merak in western and eastern Bhutan. Cattle are the main source of livelihood, contributing 71% and 84% of the herders' gross annual household income in Haa and Merak, respectively. Transhumance is a direct response to cold temperatures, shortage of forage, and the search for livelihood opportunities. Grazing rights over rangeland are individual and community-owned. Grazing regulations are based on mutual understanding and equity among high-elevation pastoralists and low-elevation sedentary cattle owners. The sustained use of rangeland requires accommodation of traditional rights and more clarity about ownership and rangeland management. Temperate forests and grasslands along the established migratory livestock routes exhibit signs of overgrazing that vary with forest types. Rotational grazing is recommended, particularly on severely depleted ranges.
On Diffusion in Fractal Soil Structures

Fractal models of soil structure can be used to predict the scaling properties of associated transport coefficients. For gas diffusion, the structure of the soil pore space is relevant, while the structure of the solid matrix is most implicated in heat conduction. In fractal soil structures, the magnitude of the relevant diffusivities can be written in the generic form D (r) = A (r − ϕ), where D(r) is a length-dependent diffusion coefficient, A is the normalization coefficient, r is the Pythagorean length, and ϕ is a structure-dependent constant. The dependence of ϕ on structure has been described elsewhere; however, the influence of structure on the magnitude of A has not been previously elaborated. Here, we determine the functional dependence of A on the structural parameters of the soil. The heterogeneity and connectivity, as quantified by the mass fractal dimension (D ₘ) and spectral dimension (d), respectively, and porosity are estimated from sections of undisturbed soil cores. For these soil structures, we demonstrate that the magnitude of the thermal and gas diffusivities is more sensitive to the porosity than to the scale dependency inherent in fractal structures. A methodology is developed and applied to rank the predicted thermal and gas diffusivities for the soil structures studied.
Finnish supra-long tree-ring chronology extended to 5634 BC

Dendrochronological crossdating was used to expand a pre-existing multi-millennial tree-ring chronology for Finnish Lapland. Twelve tree-ring series from sedimentary archives of five small lakes contributed to the oldest part of the chronology, extending the record to 5634 BC (previously 5520 BC). Today, the chronology is the longest conifer tree-ring chronology in Eurasia. The geologically oldest pine megafossils were found the eastern part of the region, i.e. north-east Finnish Lapland, and this is also where the authors expect that other very old pine megafossils may be found in the future. Cool climatic conditions c.8 ka ago may have prevented pine regeneration in the tundra-forest ecotone. This may explain the practical difficulty of making the chronology longer than its present form in the study region.
Observed trends in the global jet stream characteristics during the second half of the 20th century

In this paper, we propose a new method based on the detection of jet cores with the aim to describe the climatological features of the jet streams and to estimate their trends in latitude, altitude, and velocity in the National Centers for Environmental Prediction (NCEP)/National Center for Atmospheric Research (NCAR) and 20th Century reanalysis data sets. Due to the fact that the detection method uses a single grid point to define the position of jet cores, our results reveal a greater latitudinal definition allowing a more accurate picture of the split flow configurations and double jet structures. To the best of our knowledge, these results provide the first multiseasonal and global trend analysis of jet streams based on a daily‐resolution 3‐D detection algorithm. Trends have been analyzed over 1958–2008 and during the post‐satellite period, 1979–2008. We found that, in general, trends in jet velocities and latitudes have been faster for the Southern Hemisphere jets and especially for the southern polar front jet which has experienced the fastest velocity increase and poleward shift over 1979–2008 during the austral summer and autumn. Results presented here show an acceleration and a poleward shift of the northern and southern winter subtropical jets over 1979–2008 that occur at a faster rate and over larger zonally extended regions during this latter period than during 1958–2008.
Surface flux estimation using radiometric temperature: A dual‐temperature‐difference method to minimize measurement errors

Surface temperature serves as a key boundary condition that defines the partitioning of surface radiation into sensible and latent heat fluxes. Surface brightness temperature measurements from satellites offer the unique possibility of mapping surface heat fluxes at regional scales. Because uncertainties in satellite measurements of surface radiometric temperature arise from atmospheric corrections, surface emissivity, and instrument calibrations, a number of studies have found significant discrepancies between modeled and measured heat fluxes when using radiometric temperature. Recent research efforts have overcome these uncertainties and in addition have accounted for the difference between radiometric and aerodynamic temperature by considering soil and vegetative‐canopy aerodynamic resistances. The major remaining obstacle to using satellite data for regional heat flux estimation is inadequate density of near‐surface air temperature observations. In this paper we describe a simple, operational, double‐difference approach for relating surface sensible heat flux to remote observations of surface brightness temperature, vegetative cover and type, and measurements of near‐surface wind speed and air temperature from the synoptic weather network. A double difference of the time rate of change in radiometric and air temperature observations is related to heat flux. This double‐difference approach reduces both the errors associated with deriving a radiometric temperature and with defining meteorological quantities at large scales. The scheme is simpler than other recent approaches because it requires minimal ground‐based data and does not require modeling boundary layer development. The utility of this scheme is tested with ground‐based radiometric temperature observations from several arid and subhumid climates with a wide range of vegetative cover and meteorological conditions.
