Poly(sodium styrenesulfonate)–block–poly(acrylic acid) (PNaSS–b–PAA) and poly(sodium styrenesulfonate)–block–poly(N-isopropylacrylamide) (PNaSS–b–PNIPAM) were prepared via reversible addition–fragmentation chain transfer (RAFT) radical polymerization using a PNaSS-based macro-chain transfer agent. The molecular weight distributions (Mw/Mn) of PNaSS–b–PAA and PNaSS–b–PNIPAM were 1.18 and 1.39, respectively, suggesting that these polymers have controlled structures. When aqueous solutions of PNaSS–b–PAA and PNaSS–b–PNIPAM were mixed under acidic conditions, water-soluble PNaSS–b–PAA/PNaSS–b–PNIPAM complexes were formed as a result of hydrogen bonding interactions between the pendant carboxylic acids …read more

In this work, we investigate the effect of HNO3 anodizing solution concentration ranging from 1.5 to 3 M on H2-sensing performance of 2D WO3 nanostructures prepared by anodizing sputtered tungsten films. The thickness of WO3 nanosheets was found to reduce while the crystallinity degraded with increasing HNO3 concentration. However, the nanosheets anodized in 2 M HNO3 exhibited the highest response of 43.4 to 1 vol % H2, which was one order of magnitude larger than those fabricated with …read more

We report the design of a silicon chip dedicated to the in-situ monitoring of soil nitrogen cycle in wheat crop. Our study shows that ion-sensitive field effect transistor (ISFET) microsensors are suitable for quick on-site or long-term analysis of nutrients measured directly in soil as opposed to soil extracts analysis. Our pH-ISFET recorded soil pH for six months with results in good accordance with standard sampling method and without any loss of …read more

In this study, we developed an appropriate calorie tracking algorithm for children and compared it with the current commercial product. The results of the developed algorithm showed 94.2% accuracy in the classification of intermittent activities: sitting down, standing up, turning around and jumping; and 92.9% accuracy in the classification of continuous activities: walking, running, stair climbing, and jumping rope. This comparison shows that the developed algorithm outperforms the commercialized one and shows it is suitable for actual use …read more

Thai Activist Jailed for the Crime of Sharing an Article on Facebook

By gennie

Thai activist Jatuphat “Pai” Boonpattaraksa was sentenced this week to two and a half years in prison—for the crime of sharing a BBC article on Facebook. The Thai-language article profiled Thailand’s new king and, while thousands of users shared it, only Jutaphat was found to violate Thailand’s strict lese majeste laws against insulting, defaming, or threatening the monarchy.

The sentence comes after Jatuphat has already spent eight months in detention without bail. During this time, Jatuphat has fought additional charges for violating the Thai military junta’s ban on political gatherings and for other activism with Dao …read more

Bike Gear Company Nearly Run Over by Patent Troll

By elliot

Rick Pepper is passionate about designing cool products for cyclists and other adventurous types. He started his company Elevengear as a one-person shop in 2007, and it’s since grown to a small, successful team. But all of that could have changed when his company was sued for allegedly infringing a group of obscure patents on delivery and tracking protocols.

Before Rick even realized that he’d been sued, his inbox was flooded with solicitations from lawyers offering to take on his case. “I remember getting an email that I thought was super spammy,” Rick recalls. “It said something like, ‘Hey, since …read more

“Suddenly a lot of companies started focusing on producing services in the cloud. I like to call it Cloud Native – everything is built for the cloud. The main concept there is to enable developers to work fast,” explained Ben Bernstein, CEO & Co-Founder of Twistlock, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.

Envisioning the AI-Driven Enterprise | @CloudExpo #AI #ML #DL DX #DeepLearning

As today’s digital disruptions bounce and smash their way through conventional technologies and conventional wisdom alike, predicting their path is a multifaceted challenge. So many areas of technology advance on Moore’s Law-like exponential curves that divining the future is fraught with danger. Such is the problem with artificial intelligence (AI), and its related concepts, including cognitive computing, machine learning, and deep learning.

[session] #Blockchain for Business | @CloudExpo @IBMcloud #AI #ML #DX #FinTech #Bitcoin

Blockchain is a shared, secure record of exchange that establishes trust, accountability and transparency across business networks. Supported by the Linux Foundation’s open source, open-standards based Hyperledger Project, Blockchain has the potential to improve regulatory compliance, reduce cost as well as advance trade. Are you curious about how Blockchain is built for business? In her session at 21st Cloud Expo, René Bostic, Technical VP of the IBM Cloud Unit in North America, will discuss the basics of Blockchain, preview the Blockchain Reference Architecture, and introduce the mechanics of a Blockchain Business Network.
