MIT Researchers have Developed Model that can Predict Mortality Risk in ICU Patients

Researchers from the Massachusetts Institute of Technology have developed a new machine-learning model that groups patients into subpopulation according to their health status and predicts the patient’s risk of dying during their stay in intensive care unit (ICU). This model is effective enough that it outclasses global mortality prediction models and exposes performance disparities of those models across specific patient subpopulation.

The patients in the ICU contains wide range of health conditions and are dependent on the way treatment that will be provided to them. Patients undergo various physiological tests such as checking vital signs and bloodwork, to decide if the patient is at immediate risk of dying if not treated actively.

In last few years, various models have been developed to predict mortality in ICU, depending on the different health factors seen during their stay. Various models either have drawback with the patient subpopulation or have limited data for testing and training.

But, in the paper presented by MIT researchers at Proceedings of Knowledge Discovery and Data Mining conference, showed that machine-learning model by them can perform better in both the conditions. It has the ability to share data across all subpopulation to get better predictions and trains specifically on patient subpopulation. Thus, by having both the functions the model can predict patient’s risk of mortality within the first two days of their stay in ICU. The model has been compared to strictly global and other models.

Global Modified Bitumen Market to Rise Owing to Elasticity of Product

San Francisco, California, August 31, 2018: Bitumen is mainly used in the construction industry alongside other materials for building roads and roofs. This is because of its excellent water proofing and thermoplastic behavior. A modified bitumen is a more evolved version that is chemically fortified. A report on its market by TMR Research, titled, “Modified Bitumen Market – Global Industry Analysis, Size, Share, Trends, Analysis, Growth, and Forecast 2017–2025,” finds that the high resistance of the product to permanent deformation is one of its greatest USPs. It proves particularly useful when used alongside asphalt for building roads meant to withstand extreme temperatures or heavy traffic.

The global modified bitumen market is predicted to soar owing to the products increased elasticity, greater lifespan, lesser maintenance costs, and better drainage properties. Massive opportunities are being generated in the market owing to increasing industrialization and urbanization which are leading to increased construction activities. Apart from building and road construction, modified bitumen market is also receiving a boost because of the waterproofing applications of the product.

Plastomers and thermoplastic elastomers mostly used for bitumen modification are styrene-butadiene-styrene (SBS), polypropylene (PP), ethylene-butyl acrylate (EBA), styrene-isoprenestyrene (SIS), ethylene-vinyl acetate (EVA), atactic polypropylene (APP), crumb rubber, and natural rubber. Currently, the SBS account for a substantial share in the global modified bitumen market; the properties it imparts to bitumen has greatly served to enhance its application areas.

Geographically, the global modified bitumen market is mainly being led by Asia Pacific and Latin America because of the increasing infrastructure building in the regions. Some of the key players operating in the global modified bitumen market that have been profiled in the report are Nynas AB, Royal Dutch Shell Plc., Sika AG, and Total S.A. The report throws light on their sales and revenues, market shares, and growth prospects going forward.

Modified Bitumen Market Soars due to Upswing in Construction Activities Worldwide

San Francisco, California, New York, May 29, 2017: A new market research report by TMR Research, titled, “Modified Bitumen Market – Global Industry Analysis, Size, Share, Trends, Analysis, Growth, and Forecast 2017–2025,” presents a detailed overview of the global market. Analyzing the market for developmental trends of the past, the report also presents a forecast of the state of the market from 2017 to 2025.

Modified bitumen demonstrates strong resistance to permanent deformation, particularly when mixed with asphalt for building roads meant for heavy traffic or in harsh conditions. Adding modifying binders to conventional bitumen also prevents it from cracking, ageing, stripping, and thermal fissures. On account of so many benefits of modified bitumen in addition to better elasticity of the bitumen, its market is seeing steady growth.

The booming construction industry has majorly boosted the global modified bitumen industry. Modified bitumen is being increasingly used in building roads and roofs. A modified bitumen roof system is a hybrid, asphalt built-up roof (BUR). It has the benefits of the built-in redundancy of the BUR, along with the higher strength, flexibility, and UV resistance of a modified membrane. The fast-paced industrialization worldwide is also said to be stoking the modified bitumen market.

One factor acting as a deterrent to the market is the limited number of oil resources capable of producing such high-quality bitumen.

Thermoplastic elastomers and plastomers that find application in bitumen modification are ethylene-butyl acrylate (EBA), styrene-butadiene-styrene (SBS), styrene-isoprenestyrene (SIS), polypropylene (PP), atactic polypropylene (APP), ethylene-vinyl acetate (EVA), natural rubber, and crumb rubber. Among them, SBS accounts for maximum market share both volume- and value-wise. This is because of its use across numerous industries.

The prominent end-use segments in the global modified bitumen market are road construction, building construction, and waterproofing. Currently, the road construction segment grosses maximum revenue as a lion’s share of the bitumen produced worldwide is used in the segment. Going forward too, the segment will contribute the most to the revenue.

Geographically, the key segments of the global modified bitumen market are Europe, North America, Asia Pacific, and the Middle East and Africa. Among them, Asia Pacific and the Middle East and Africa are said to be leading the charge on account of the developing nations in the regions driving up demand for modified bitumen for road construction. This in turn is a result of the massive thrust on infrastructure building in such regions.

In order to assess the competition prevailing in the global modified bitumen market, the report profiles players such as Royal Dutch Shell Plc., Nynas AB, Sika AG, and Total S.A.
