A self-monitoring time series database system which enforces usage policies is described. A time series database system receives an alert trigger condition for a system user, wherein the system user is associated with multiple time series data points corresponding to multiple subsystems of the time series database system. The time series database system aggregates the multiple time series data points in an internal time series data point, which is internal to the time series database system, associated with the system user. The time series database system evaluates whether the internal time series data point associated with the system user meets the alert trigger condition. The time series database system reduces a level of access by the system user to the time series database system in response to an evaluation that the internal time series data point associated with the system user meets the alert trigger condition.

• Dockworkers in Belgium are wearing bracelets to enforce social distancing.
• The bracelets were already used to detect if someone fell into the water, but now they will sound an alarm if workers get to close to each other.
• Manufacturers say there is no privacy issue and the bracelets don't track workers' locations, despite concerns.
• Visit Business Insider's homepage for more stories.

Quarantine and social distancing are going high-tech as countries and companies embrace wearables. In Antwerp, Belgium, dockworkers are instructed to wear bracelets that enforce social distancing rules while they work.

Europe, where more than 100,000 people have died from COVID-19, is slowly starting to reopen in some places. Stay at home orders are expiring in many countries, while nonessential travel has stopped across the EU, and countries look towards the summer to anticipate what kind of travel might be possible. 

People are beginning to go back to work, which in some sectors means inevitable close contact, especially in many essential jobs. Social distancing bracelets in Belgium are one idea bing tested to see what the future of work might look like after coronavirus.

Here's how it works. 

SEE ALSO: People arriving in Hong Kong must wear tracking bracelets for 2 weeks or face jail time. Here's how they work.

The black, plastic bracelets are worn on the wrist like a watch.

They're made by Belgian company Rombit, which says that they are "a fully integrated personal safety and security device, specifically designed for highly industrial environments."

Source: Romware

Rombit already made bracelets useful in the port setting, which could be used to call for help if a worker fell into the water or another accident occurred.

Europe is slowly starting to go back to work, but fears of a second wave are making officials cautious.

Contact tracing is one solution being explored around the world, and the manufacturers of the bracelet believe it could also be used for contact tracing.

Source: The Associated Press

European health guidances say to wash hands, wear masks, and keep at least 1.5 meters, or about five feet, apart.

When two workers are less than five feet apart, the bracelets will sound warnings.

Rombit CEO John Baekelmans told Reuters that the bracelets won't allow companies to track employees' locations, because the devices are only connected to each other. He says there is no central server.

Workers in the control tower will be the first to test the bracelets early this month.

Then, the Port of Antwerp will likely expand the devices to tug boat workers.

Baekelmans told Reuters that Rombit already had hundreds of requests in 99 countries, and is hoping to ramp up production to 25,000 in a few weeks.

Protein tyrosine kinases (PTKs) play key roles in cellular signal transduction, cell cycle regulation, cell division, and cell differentiation. Dysregulation of PTK-activated pathways, often by receptor overexpression, gene amplification, or genetic mutation, is a causal factor underlying numerous cancers. In this study, we have developed a parallel reaction monitoring (PRM)-based assay for quantitative profiling of 83 PTKs. The assay detects 308 proteotypic peptides from 54 receptor tyrosine kinases and 29 nonreceptor tyrosine kinases in a single run. Quantitative comparisons were based on the labeled reference peptide method. We implemented the assay in four cell models: 1) a comparison of proliferating versus epidermal growth factor (EGF)-stimulated A431 cells, 2) a comparison of SW480Null (mutant APC) and SW480APC (APC restored) colon tumor cell lines, and 3) a comparison of 10 colorectal cancer cell lines with different genomic abnormalities, and 4) lung cancer cell lines with either susceptibility (11-18) or acquired resistance (11-18R) to the epidermal growth factor receptor tyrosine kinase inhibitor erlotinib. We observed distinct PTK expression changes that were induced by stimuli, genomic features or drug resistance, which were consistent with previous reports. However, most of the measured expression differences were novel observations. For example, acquired resistance to erlotinib in the 11-18 cell model was associated not only with previously reported upregulation of MET, but also with upregulation of FLK2 and downregulation of LYN and PTK7. Immunoblot analyses and shotgun proteomics data were highly consistent with PRM data. Multiplexed PRM assays provide a targeted, systems-level profiling approach to evaluate cancer-related proteotypes and adaptations. Data are available through Proteome eXchange Accession PXD002706.

Niemann-Pick disease type C (NPC) disease is a lipid-storage disorder that is caused by mutations in the genes encoding NPC proteins and results in lysosomal cholesterol accumulation. 2-Hydroxypropyl-β-cyclodextrin (CD) has been shown to reduce lysosomal cholesterol levels and enhance sterol homeostatic responses, but CD’s mechanism of action remains unknown. Recent work provides evidence that CD stimulates lysosomal exocytosis, raising the possibility that lysosomal cholesterol is released in exosomes. However, therapeutic concentrations of CD do not alter total cellular cholesterol, and cholesterol homeostatic responses at the ER are most consistent with increased ER membrane cholesterol. To address these disparate findings, here we used stable isotope labeling to track the movement of lipoprotein cholesterol cargo in response to CD in NPC1-deficient U2OS cells. Although released cholesterol was detectable, it was not associated with extracellular vesicles. Rather, we demonstrate that lysosomal cholesterol trafficks to the plasma membrane (PM), where it exchanges with lipoprotein-bound cholesterol in a CD-dependent manner. We found that in the absence of suitable extracellular cholesterol acceptors, cholesterol exchange is abrogated, cholesterol accumulates in the PM, and reesterification at the ER is increased. These results support a model in which CD promotes intracellular redistribution of lysosomal cholesterol, but not cholesterol exocytosis or efflux, during the restoration of cholesterol homeostatic responses.
