Sensors, Vol. 19, Pages 3073: An Improved Time-Series Model Considering Rheological Parameters for Surface Deformation Monitoring of Soft Clay Subgrade

In this study, we propose an improved time-series deformation model considering rheological parameters (viscosity and elasticity) based on the Kelvin model. The functional relationships between the rheological parameters and deformation along the Synthetic Aperture Radar ( SAR) line of sight are constructed, and a method for rheological parameter estimation is provided. To assess the feasibility and accuracy of the presented model, both simulated and real deformation data over a stretch of the Lungui highway (built on soft clay subgrade in Guangdong province, China) are investigated with TerraSAR-X satellite imagery. With the proposed deformation model, the unknown rheological parameters over all the high coherence points are obtained and the deformation time-series are generated. The high-pass (HP) deformation component and external leveling ground measurements are utilized to assess the modeling accuracy. The results show that the root mean square of the residual deformation is ±1.6 mm, whereas that of the ground leveling measurements is ±5.0 mm, indicating an improvement in the proposed model by 53%, and 34% compared to the pure linear velocity model. The results indicate the reliability of the presented model for the application of deformation monitoring of soft clay highways. The estimated rheological parameters can be provided as a reference index for the interpretation of long-term highway deformation and the stability control of subgrade construc...

Conclusions: Simultaneous accelerated CXL and refractive surgery is effective for the treatment of myopia. However, it is as yet unclear if the additional CXL step reduces the incidence of iatrogenic keratectasia. Further long-term comparative studies would be useful in evaluating safety and efficacy of this procedure. More research should also be performed to titrate the UV-A irradiation settings for an optimal outcome. PMID: 31411927 [PubMed - as supplied by publisher]

There are numerous candidates for most bizarre passage in the Bible. The circumcision of Moses is right up there, for example. Exodus 17 is actually two episodes -- remember that the division into chapter and verse was done my Medieval monks and does not represent any indigenous property of the text. The first story is well known, though it is rather strange. The second story, however . . . deeply, profoundly wacko. Here goes.The whole Israelite community set out from the Desert of Sin, traveling from place to place as theLord commanded. They camped at Rephidim, but there was no water for the people to drink.2 So they...

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined. Mean nonfasting cholesterol concentration was 72...

Purpose of review To offer an update on advances and controversies in the assessment, investigation and treatment of thyroid eye disease (TED), a disfiguring orbital autoimmune disease, which can manifest with diplopia and threaten not only sight – but also life. Recent findings Developments in biomarkers and imaging are helping to tailor the management of patients. Emerging therapies target different pathways in the disease and are informed by studies into TED pathogenesis: the last 2 years has, for example, seen the culmination of a two-decade long bench-to-bedside story in which an original focus on the IGF1 ...

Conclusions: This study presents the simulated effectiveness of a hypothetical intersection active safety system on real crashes that occurred in the United States. This work shows that there is a strong potential to reduce crashes and injuries in the United States. PMID: 31381453 [PubMed - in process]

It’s only been seven years since scientists first learned how to precisely and reliably splice the human genome using a tool called CRISPR, making it possible to think about snipping out disease-causing mutations and actually cure, once and for all, genetic diseases ranging from sickle cell anemia to certain types of cancer and even blindness. Doctors are plunging ahead in search of ways to use the relatively new technology to start treating patients. In China last November, scientist Jiankui He stunned—and dismayed—the genetic community when he announced he had already used CRISPR, which many believe sti...

Much of the proceedings at Undoing Aging in Berlin earlier this year were recorded, but of course it takes a few months for everything to process through the queue. I briefly escaped from the conference for an ad hoc, unstructured discussion with Adam Ford of Science, Technology, and the Future, who, like the Life Extension Advocacy Foundation folk, was interviewing as many people as he could during the event. It wound up a monologue on topics that were at the top of my mind at the time, particularly the present state of funding and the transformation of our community from a primary focus on advocacy and academic research ...

Conclusions: Present case is the first to describe the unusual presentation of progressive high hypermetropia in a child with Axenfeld- Rieger anomaly with congenital glaucoma after surgical intervention for glaucoma. Childhood glaucoma is classically associated with myopic shift in refraction and refraction is one of the most important clinical parameter measured at every follow-up visit. Although progressive hypermetropic shift is a rare occurrence, clinicians should be aware of this possibility. Keratomerty should be performed when such refractive surprises arise, which may help detect the clinical condition and the e...

One of the few hopeful, “glass-half-full” thoughts I had after Donald Trump won the election in 2016 was that the new president would prove to be the best salesman of free trade since Adam Smith. No, I wasn’t so deluded to think he’d articulate the case for free trade and commit himself to removing all protectionis t barriers. On the contrary, I assumed Trump’s reckless deployment of tariffs and other trade restrictions would backfire so spectacularly and expose the folly of protectionism so convincingly that the economically discredited philosophy would become politically radioactive, once an...
