Central venous pressure correlates with inferior vena cava collapsibility index in patients treated in intensive care unit

open access: yesBali Journal of Anesthesiology, 2017
Background: Intravascular volume status is an important parameter in monitoring the patients treated at intensive care unit (ICU), so accuracy and strict monitoring of fluid volume is one factor that influence patient's health status. Amongst others, two

Comparative Study between Silica Fume and Nano Silica Fume in Improving the Shear Strength and Collapsibility of Highly Gypseous Soil

open access: yesTikrit Journal of Engineering Sciences, 2020
Soils with highly gypsum content signify known as soils that exhibit collapsibility and sudden failure when being submerged to wetting. Many of the constructions built on this soil showed cracked and/or collapsed at some parts as these soils immersed or ...

Parametrized Complexity of Expansion Height [PDF]

open access: yes, 2019
Deciding whether two simplicial complexes are homotopy equivalent is a fundamental problem in topology, which is famously undecidable. There exists a combinatorial refinement of this concept, called simple-homotopy equivalence: two simplicial complexes ...

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

open access: yesAdvanced Science, EarlyView.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

Bioinspired Adaptive Leg‐Claw Enables Robust Perching and Grasping for UAVs

open access: yesAdvanced Science, EarlyView.
Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...

Multi-stratigraphic centrifugal model test method for determination of self-weight collapsible deformation of loess

open access: yesYantu gongcheng xuebao, 2020
The self-weight collapsible deformation of loess is harmful to the upper buildings. The existing indoor collapsibility and on-site water immersion test method for loess are difficult to satisfy the requirements of the project construction in terms of the

Conditional and marginal relative risk parameters for a class of recursive regression graph models

open access: yes, 2018
In linear regression modelling the distortion of effects after marginalizing over variables of the conditioning set has been widely studied in several contexts. For Gaussian variables, the relationship between marginal and partial regression coefficients

Cosmogenesis and Collapse [PDF]

open access: yesFoundations of Physics, 2010
For a festschrift in Foundations of Physics in honor of Daniel Greenberger and Helmut Rauch in Foundations of Physics. This updates the previous version by adding an appendix (Appendix B) which contains the exact solution of a partial differential equation of importance in the ...

Development of interactive MRI‐based 3D visualization tools for neuroanatomy education in Latin America

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The study of neuroanatomy is fundamental in many scientific fields. Despite this, it is a challenging subject for students. As technology evolves, it is being increasingly incorporated into educational methods, including the teaching of neuroanatomy. Three‐dimensional (3D) visualizations are well suited for displaying neuroanatomy.

Collapsibility of CAT(0) spaces

open access: yes, 2019
Collapsibility is a combinatorial strengthening of contractibility. We relate this property to metric geometry by proving the collapsibility of any complex that is CAT(0) with a metric for which all vertex stars are convex.
