Retrospective Review of Fluoroscopic Swallowing Studies and Outcomes at an Academic Health Center [PDF]
, 2020 Introduction: Aspiration is often associated with underlying medical conditions and can cause pneumonia or death. Aspiration risk can be assessed via video fluoroscopic swallowing study (VFSS) or barium swallow (BaSw).

A Novel Intelligent Method for Predicting the Penetration Rate of the Tunnel Boring Machine in Rocks
, 2020 In the construction of rock tunnels, the penetration rate of the tunnel boring machine (TBM) is influenced by many factors (e.g., geomechanical parameters), some of which are highly uncertain.

PREDICTION OF TBM PENETRATION RATE USING SUPPORT VECTOR MACHINE
Geosaberes, 2020 One of the most important issues in mechanized excavating is to predict the TBM penetration rate. Understanding the factors influencing the rate of penetration is important, which allows for a more accurate estimation of the stopping and excavating times

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Influence of sperm-oocyte coincubation period on porcine in vitro fertilization (IVF) efficiency [PDF]
, 2010 A major obstacle for successful in vitro production of porcine embryos is the polyspermic fertilization. One possibility to reduce polyspermic penetration is decreasing the number of spermatozoa added to the fertilization medium. Unfortunately, the lower

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Factors Affecting Penetration Rate
Journal of the Japanese Association for Petroleum Technology, 1965 By the use of drilling records taken in oil fields in Japan, the factors affecting penetration rate of a rotary drilling were analysed. Some of the results obtained are as follows: (1) In some fields there is a relationship between load on a bit and penetration rate both for vertical wells and directional wells drilled with a vertical deviation angle ...
