Prediction of Hypotension During Neuraxial Anesthesia in Patients with Pregnancy-Induced Hypertension Through Subclavian Vein Collapsibility Index

: Objective: To explore and evaluate the predictive value of subclavian vein collapsibility index (SCV-CI) on hypotension during neuraxial anesthesia in patients with pregnancy-induced hypertension (PIH). Methods: Pregnant women with PIH who underwent elective cesarean section in our hospital from January to July 2021 were selected as the research subjects. Patients who experienced hypotension during anesthesia were included into the hypotension group, whereas patients who had a normal blood pressure during anesthesia were included in the normotensive group. The SCV-CI was then calculated for three respiratory cycles, the average value was taken as the base value, and the patient was monitored for another 20 minutes. The blood pressure, heart rate, blood oxygen saturation, and SCV-CI of the patients were measured, and the incidence of maternal nausea and vomiting and cord blood gas were recorded. Then, a correlation analysis was conducted on the relationship between subclavian vein collapsibility index and hypotension. A receiver operating characteristic curve was drawn to seek the threshold value of subclavian vein collapsibility index for post-anesthesia hypotension. Results: There was no significant difference in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) between the two groups before anesthesia ( P > 0.05 ). After anesthesia, the above indexes (SBP, 103.25 ± 12.48 mmHg; DBP, 58.94 ± 7.46 mmHg; and HR, 52.96 ± 6.48 beats/min) were significantly lower than those of the normal blood pressure group, and the difference was statistically significant ( P < 0.05). In comparison, the SCV-CI in the hypotension group was 35.82 ± 4.93% greater than that in the normal blood pressure group (23.85 ± 5.27%), and the incidence of nausea and vomiting in the hypotension group (40.0%) was significantly higher than that in the normotensive group (10.53%), and the difference was statistically significant ( P < 0.05). The area under the curve of SCV-CI prediction against hypotension in patients with PIH under neuraxial anesthesia was 0.825 (95% CI: 0.762–0.893, P < 0.001), the cut-off value was 25.68%, the predictive sensitivity was 92.68%, and the specificity was 81.24%. Conclusion: SCV-CI has a good predictive value for the occurrence of hypotension in patients with PIH during neuraxial anesthesia
Genetic effects of the introduction of Quercus rubra to Germany

Northern red oak ( Quercus rubra ) was introduced to Europe in the late 17th century and is today the most important deciduous foreign tree species in Germany. Despite its importance little is known about the origin of local red oak stands and patterns of genetic variation in German red oak stands. To be able to make recommendations regarding the adaptive potential of red oak and the selection of provenances with respect to climate change, a better understanding of the genetic diversity and structure of German red oak stands is needed. Therefore, individuals from 62 stands in Germany and North America were genotyped at five chloroplast microsatellite loci to characterize chloroplast haplotype diversity and geographical structure. Compared to reference stands from the natural distribution range, German stands demonstrated a relatively low genetic differentiation among populations and represented only a fraction of the haplotype diversity found in North America. For several stands located in the south of Germany a considerably higher haplotype diversity was found. Therefore, we conclude that German stands originated from a limited geographic range within the natural distribution, which was possibly located in the northern part of the native distribution range. While most German stands showed signatures of founder effects due to originating from a small number of individuals within a limited range, particularly stands in the south of Germany could have benefited from admixture and multiple introductions of different North American provenances.

Power factor correction stage and matrix zero voltage switching resonant inverter for domestic induction heating appliances

The technology of ﬂexible cooking surfaces applied to domestic induction heating (IH) appliances offers several advantages that improve the experience of the users, not only because the safety or cleanness, but also due to the fast heating and ﬂexibility. These cook-tops have more challenging design requirements because of different mains connections, efﬁciency requirements, electromagnetic compatibility (EMC) standards, control complexity, and cost. In previous works, the use of a front-end power factor corrector (PFC) rec-tiﬁer has been proposed to overcome these restrictions. In order to get a cost-effective implementation, this paper proposes the use of a front-end PFC stage and a matrix resonant inverter, which features zero voltage switching (ZVS), to achieve a reduced number of power devices, and get a high performance and reduced power losses in the converter. Finally, an experimental prototype with four outputs of 3.6 kW has been implemented to prove the feasibility of this proposal.
Chapter 23 LFG and historical linguistics

This chapter looks at the opportunities and perspectives that LFG offers for the study of language change, surveying existing LFG approaches within historical linguistics and providing examples of sample phenomena. We discuss how reanalysis, a major driver of language change, can be accounted for elegantly within LFG’s parallel architecture thanks to its crucial separation of form from function and, moreover, how different types of reanalysis can be understood, whether they involve rebracketing, recategorization, or changes at the lexical level commonly discussed in terms of grammaticalization. As we also discuss, LFG’s fundamental design principles and resulting flexibility of c-structure allow for complex, nuanced accounts of word order change. Furthermore, we survey the opportunities that LFG offers for exploring the complex relationship between variation and change, and in particular frequency effects and gradual change which proceeds via competition. Finally, we signpost future possibilities for work in this relatively underexplored but promising area.
Modelling of the wave propagation, the coastal currents and the induced topographic changes

This paper models the sea bottom evolution. This model is built up on three main parts. The first one describes the wave propagation, taking simultaneously into account the refraction, the diffraction and the reflection but also the energy dissipation caused by wave breaking. This model is solved by the numerical method of the finite volumes, using an iterative resolution (the GMRES method). Several validations of this model have been carried out on many examples such as harbors of various geometries and depths, beaches,. The wave induced currents are computed in the second part based on the concept of the radiation stresses describing the excess of the flux momentum caused by the waves. A model based on the complete Navier-Stokes equations integrated on the depth and associated with appropriated forcing and friction terms is used. This model is computed as an update of WOLF software (HACH, ULg) and is applied to some examples such as beaches with or without coastal structures. Finally, the third part is about the sediment transport. It exhibits the topographic modifications of the coastal sea bottom caused by the waves and their currents. A loop execution of these three models ends this work. It gives us an operational tool to describe the topographic evolution of the coastal areas caused by the incident waves, the induced currents and then the resulting sediment transport, fulfilling the objectives of this paper.
Quantifying Habitat Relationships of Songbirds in Quaking Aspen ( Populus tremuloides ) and Other Montane Communities of the Jarbidge Mountains, Nevada

Quaking aspen (Populus tremuloides) woodlands are expected to be sensitive to climate change, and have declined in parts of the West. Great Basin mountain ranges may be near the limits of aspen’s climatic threshold, in terms of temperature and aridity, and thus are particularly vulnerable to climate change. Birds associating with aspen are likely to undergo regional population fluctuations and changes in distribution as a result of changes in aspen availability or distribution. Thus, understanding the habitat relationships of avian communities in aspen and other montane cover types is important for tracking the impacts of future landscape change. The mountainous terrain of the HumboldtToiyabe National Forest in northern Elko County, NV, supports a patchy array of aspen and conifer forest and shrubland distributed across 2,755 km. I quantified avian abundance using point count sampling over two breeding seasons (2010 – 2011) at 389 point locations in or near systematically selected stands of aspen (n = 135). For common species, I compared the mean abundance per stand in aspen to that in conifer, mixed aspen-conifer, and montane sage, using both paired and partially-paired t-tests. Most focal species were significantly more abundant in aspen than conifer (22 of 37 species) or montane sage (30 of 39 species) in the partially-paired comparisons. In paired comparisons, 4 of 15 species were significantly more common in aspen than conifer, and 19 of 24 were significantly more common in aspen than montane sage, but most comparisons with both conifer and mixed aspen-conifer were non-significant due to small sample sizes. I then used mixed-effects multiple regression, with stand and observer crew as random effects, to identify key habitat and physiographic parameters driving species’ abundance. For 8 of 11 aspen associates in mixed-effects models, abundance increased with an increase in aspen within 75 m; abundance also decreased with an increase in conifer for three aspen associates. For three of five conifer associates, abundance increased with an increase in 75-m conifer; abundance also increased with an increase in mixed aspen-conifer for three conifer associates. The results of my study underscore the ecological importance of aspen for montane passerine communities–aspen is preferred by most species over other available habitats, and abundance of most aspen-associated species increased as the proportion of aspen within 75 m increased. A reduction in aspen distribution in the Great Basin is likely to result in a decrease in abundance and distribution of a host of aspen-associated species and could have long-term effects on montane passerine communities. I suggest that management activities promoting aspen’s persistence and resilience to climate change be considered as a means for maintaining abundance and species composition of montane bird communities in the island ranges of the Great Basin.
Solid oxide fuel cells with a thin film electrolyte: A review on manufacturing technologies and electrochemical characteristics

Solid oxide fuel cells (SOFCs) are electrochemical systems converting the energy released during fuel oxidation into electrical energy. SOFCs are considered as a promising clean energy technology due to the high efficiency of fuel-to-power conversion and environmental friendliness. The potential applications of SOFCs extend from stationary power generation units for industrial and household facilities to auxiliary power units in vehicles and portable power sources. One of the main elements of SOFCs is a solid oxide electrolyte possessing ionic conductivity at high temperatures (above 700 °C). The main challenge in the SOFC commercialization is related to their high operating temperature, which entails materials degradation, short life-time, long start-up and shut-down times, and high cost. One of the most effective ways to reduce the SOFC operating temperature is to minimize the electrolyte thickness. In this regard, fabrication of SOFCs with a thin film electrolyte has been attracting high research activity over the past few decades. Different fabrication techniques were reported to be applicable for manufacturing thin film SOFCs, and the fuel cell performance was found to be highly dependent on the appropriate selection of materials and processing technologies. The present review is focused on state-of-the-art fabrication technologies of the thin film SOFCs. A brief survey of configurations and geometries of the thin film SOFCs and methods of deposition of solid-oxide films is given. Special attention is focused on the electrical generation performance of the thin film SOFCs.
Better, Stronger Faster; How Oblique Aerial Imagery Is Changing the Face of Transportation Planning

The Federal Highway Administration (FHWA)-produced document "The Use of Imagery in Transportation Planning: A Guidebook" states that: “Effective transportation planning requires current, accurate geospatial information about the transportation infrastructure, associated interrelationships between the land use and demographics, and the ways that the land uses and demographics interact with, and use the transportation infrastructure. The increasing need to gather this information across diverse functions, scales, and ownerships has resulted in wider and more efficient use of remote sensing, geographic information systems (GIS), and associated technologies. ” Oblique Aerial Imagery is useful not only in the technical planning process from modeling to corridor analysis to small urban systems but also for assessing and analyzing environmental issues through change detection and for presentation graphics for public outreach, public involvement and decision making, where imagery can be used to convey information to the public in appealing, informative manners, not previously available to planners. Other uses include emerging planning issues such as safety and security, emergency preparedness and response, access, pedestrian safety, and infrastructure inventory to name a few. As the technology is only recently implemented for transportation applications, the paper shows a range of uses for oblique aerial imagery, and qualitative positive impact on extending staff time, resources, data accuracy and safety.
Investigating Teacher Educators’ Perceptions on Technology Integration in Teacher Preparation Programs

: The researchers focus on the TPACK framework, which is used to assess teachers' understanding of how to use technology in the classroom. The goal of the model is to define the skills and knowledge teachers need to effectively integrate technology into their lessons. Teacher educators’ can better prepare their students for the problems of the modern world by applying the TPACK. In the Pakistani setting, there is still a lack of technological integration in educational settings. The purpose of this research was to determine how well teacher educators in Karachi, Pakistan, use TPACK and associated domains in their classrooms for the preparation of future teachers. Teacher educators from private teacher education institutions of Karachi were conveniently sampled for this quantitative survey research study. Data was analyzed using SPSS, and the study's measurement and structural models were put through their paces using Smart PLS. It is one of the more sophisticated programs for structural equation modeling that uses partial least squares (PLS-SEM). The study found that teachers educators' technology and technological pedagogical knowledge significantly effects on their TPACK in a positive way. Conclusions and suggestions for further research are provided for implementing the TPACK framework in teacher education programs and designing learning strategies for enhancing instructors' pedagogical skills in light of the study's findings.
High-quality cartographic roads on high-resolution DEMs

The efficient and high quality rendering of complex road networks—given as vector data—and high-resolution digital elevation models (DEMs) poses a significant problem in 3D geographic information systems. As in paper maps, a cartographic representation of roads with rounded caps and accentuated clearly distinguishable colors is desirable. On the other hand, advances in the technology of remote sensing have led to an explosion of the size and resolution of DEMs, making the integration of cartographic roads very challenging. In this work we investigate techniques for integrating such roads into a terrain renderer capable of handling high-resolution data sets. We evaluate the suitability of existing methods for draping vector data onto DEMs, and we adapt two methods for the rendering of cartographic roads by adding analytically computed rounded caps at the ends of road segments. We compare both approaches with respect to performance and quality, and we outline application areas in which either approach is preferable.
Evaluation of the Linear Box-Spline Filter from Trilinear Texture Samples: A Feasibility Study

The major preference for applying B-spline filtering rather than non-separable box spline filtering on the BCC lattice is the fact that separable filtering can be performed more efficiently on current GPUs due to the utilization of the hardware-accelerated trilinear texture fetching. In order to make a fair comparison, a similar, efficient evaluation scheme is required that uses trilinear texture fetches instead of nearest-neighbor ones also for the box splines. Thus, in this paper, we propose an evaluation scheme for the linear BCC box spline built upon a trilinear B-spline basis. We compare our trilinearly evaluated linear box spline scheme to the latest method, that uses twice as many nearest neighbor fetches. Then we give a comparison to the major competitive methods: the BCC B-spline filtering and the BCC DC-spline filtering in terms of their performance.
A review of the insects and related arthropods of Midway Atoll

Introduction This paper presents results of a recent (1997–1999) survey of terrestrial arthropods of Midway Atoll and lists 546 species identified from 1891 to 1999. The last published compilation (Suehiro, 1960) listed 221 species, and the first complete listing from the 1923 Tanager Expedition published 38 species (Bryan et al., 1926). The increasing number of arthropod species reflected in these surveys is likely related to the increase in plant species present, increased contact between Midway and the outside world by means of surface and air vessels, and increased effort on the part of the U.S. Fish & Wildlife Service to inventory the arthropod fauna. The percentage of the fauna composed of native species (17%) is small and some of these species were not recollected during the present survey. Also, a large number (33%) of historically recorded alien species were not recollected. More recently introduced immigrants may have displaced some of them. The present list includes 205 new island records from Midway including 29 new records for the Hawaiian archipelago. Continued introductions resulting from frequent visits to Midway by uninspected air and surface vessels will result in serious pest problems there. Some observations are included on insects now present on Midway that may become serious pests if introduced to the main Hawaiian islands. Two species in particular, Protaetia pryeri (Janson) and Scudderia paronae Griffini should be monitored. Other concerns that should be addressed include ants, vespid wasps, and soil arthropods. A full bibliography of Midway terrestrial arthropod references is also included. Midway is located approximately 1200 miles northwest of Honolulu and is the second oldest (28.7 ma) emergent atoll in the Hawaiian Archipelago. In 1997, administration of Midway Atoll was transferred from the U.S. Navy to the U.S. Fish & Wildlife Service (USFWS). The USFWS, as part of an initial biological assessment of the atoll, and the Hawaii Biological Survey (HBS) at Bishop Museum supported 6 field trips to Midway to survey the terrestrial arthropod fauna. The trips were made on the following dates: 12–19 February 1997, 11–18 May 1997, 27 August–2 September 1997, 14–21 December 1997, 29 April–6 May 1998, and 20–23 October 1999. Additional material was collected with the assistance of USFWS personnel on Midway, who periodically serviced a Malaise trap in operation for an entire year. Specimens accumulated during this survey were returned to Bishop Museum in Honolulu for curatorial services and identification.
The Jingle-Jangle of Work-Nonwork Balance

We review research on work–nonwork balance to examine the presence of the jingle fallacy—attributing different meanings to a single construct label—and the jangle fallacy—using different labels for a single construct. In 290 papers, we found 233 conceptual definitions that clustered into 5 distinct, interpretable types, suggesting evidence of the jingle fallacy. We calculated Euclidean distances to quantify the extent of the jingle fallacy and found high divergence in definitions across time and publication outlet. One exception was more agreement recently in better journals to conceptualize balance as unidimensional, psychological, and distinct from conflict and enrichment. Yet, over time many authors have committed the jangle fallacy by labeling measures of conflict and/or enrichment as balance, and disagreement persists even in better journals about the meanings attributed to balance (e.g., effectiveness, satisfaction). To examine the empirical implications of the jingle and jangle fallacies, we conducted meta-analyses of distinct operational definitions of balance with job, life, and family satisfaction. Effect sizes for conflict and enrichment measures were typically smaller than effects for balance measures, providing evidence of a unique balance construct that is not interchangeable with conflict and enrichment. To begin to remedy concerns raised by our review, we propose a definition of work–nonwork balance drawing from theory, empirical evidence from our review, and normative information about how balance should be defined. We conclude with a theory-based agenda for future research.

- Range scanning of building interiors generates very large, partially spurious and unstructured point cloud data. Accurate information extraction from such data sets is a complex task due to the presence of multiple objects, diversity of their shapes, large disparity in the feature sizes, and the spatial uncertainty due to occluded regions. A fast segmentation of such data is necessary for quick understanding of the scanned scene. Unfortunately, traditional range segmentation methodologies are computationally expensive because they rely almost exclusively on shape parameters (normal, curvature) and are highly sensitive to small geometric distortions in the captured data. This paper introduces a quick and effective segmentation technique for large volumes of colorized range scans from unknown building interiors and labelling clusters of points that represent distinct surfaces and objects in the scene. Rather than computing geometric parameters, the proposed technique uses a robust Hue, Saturation and Value (HSV) color model as an effective means of identifying rough clusters (objects) that are further refined by eliminating spurious and outlier points through region growth and a fixed distance neighbors (FDNs) analysis. The results demonstrate that the proposed method is effective in identifying continuous clusters and can extract meaningful object clusters, even from geometrically similar regions.
