A device for detecting a cardiac event is disclosed. Detection of an event is based on a test applied to a parameter whose value varies according to heart rate. Both the parameter value and heart rate (RR interval) are filtered with an exponential average filter. From these filtered values, the average change in the parameter and the RR interval are also computed with an exponential average filter. Before computing the average change in the parameter, large changes in the parameter over short times, which may be caused by body position shifts, are attenuated are removed, so that the average change represents an average of small/smooth changes in the parameter's value that are characteristic of acute ischemia, one of the cardiac events that may be detected. The test to detect the cardiac event depends on the heart rate, the difference between the parameter's value and its upper and lower normal values, and its average change over time, adjusted for heart rate changes. The upper and lower normal parameter values as a function of heart rate are determined from long term stored data of the filtered RR values and parameter values. Hysteeresis related data and transitory deviations from normal (e.g. vasospasm related data) are excluded from the computation of normal upper and lower parameter bounds.

A biometric monitoring device measuring various biometric information is provided that allows the person to take and/or display a heart rate reading by a simple user interaction with the device, e.g., by simply touching a heart rate sensor surface area or moving the device in a defined motion pattern. Some embodiments of this disclosure provide biometric monitoring devices that allow a person to get a quick heart rate reading without removing the device or interrupting their other activities. Some embodiments provide heart rate monitoring with other desirable features such as feedback on data acquisition status.

A process of comminution of corn stover having a grain direction to produce a mixture of corn stover, by feeding the corn stover in a direction of travel substantially randomly to the grain direction one or more times through a counter rotating pair of intermeshing arrays of cutting discs (D) arrayed axially perpendicular to the direction of corn stover travel.

Mechanical visbreaking and pyrolysis between counter-rotating coaxial centrifugal impellers in a continuous radial counterflow process minimizes wastewater discharges. In one example, a cataclastic shear retort comminutes, shear thins, and shear heats an axial feed, such as tar sand, oil shale, coal tailings, distillation bottoms, or lignite. Pyrolyzing the feedstock in this shear retort yields a product stream of gases, naphthas, and oils which first mixes with the feedstock and then is axially extracted, while spent solids are simultaneously extruded from the periphery as coked devolatilized residue, such as char sand for upgrading soil to terra preta. Recirculation of shear-heated solids in long residence time within the shear retort brings heat from the spent solids at the periphery to the feedstock without an external heated sand loop. CO2 emissions from combustion to heat water for oil extraction are eliminated.

Viruses and other bioagents are of high medical and biodefense concern and their detection at concentrations well below the threshold necessary to cause health hazards continues to be a challenge with respect to sensitivity, specificity, and selectivity. Ideally, assays for accurate and real time detection of viral agents and other bioagents would not necessitate any pre-processing of the analyte, which would make them applicable for example to bodily fluids (blood, sputum) and man-made as well as naturally occurring bodies of water (pools, rivers). We describe herein a robust biosensor that combines the sensitivity of surface acoustic waves (SAW) generated at a frequency of 325 MHz with the specificity provided by antibodies and other ligands for the detection of viral agents. In preferred embodiments, a lithium tantalate based SAW transducer with silicon dioxide waveguide sensor platform featuring three test and one reference delay lines was used to adsorb antibodies directed against Coxsackie virus B4 or the negative-stranded category A bioagent Sin Nombre virus (SNV), a member of the genus Hantavirus, family Bunyaviridae, negative-stranded RNA viruses. Rapid detection (within seconds) of increasing concentrations of viral particles was linear over a range of order of magnitude for both viruses, although the sensor was approximately 50×104-fold more sensitive for the detection of SNV. For both pathogens, the sensor's selectivity for its target was not compromised by the presence of confounding Herpes Simplex virus type 1. The biosensor was able to detect SNV at doses lower than the load of virus typically found in a human patient suffering from hantavirus cardiopulmonary syndrome (HCPS). Further, in a proof-of-principle real world application, the SAW biosensor was capable of selectively detecting SNV agents in complex solutions, such as naturally occurring bodies of water (river, sewage effluent) without analyte pre-processing.

Christopher Larkin's score for Hollow Knight is one of the most beloved soundtracks in recent games. I talked with arranger David Peacock and pianist Augustine Mayuga Gonzales about their project to adapt Chris' haunting music for solo piano. David says he appreciates Christopher's involvement in developing the arrangements. He says Chris advised him to use the lore of the game as inpiration for his arrangements. Augustine says he loved playing David's arrangements because they were challenging, but also allowed him to use his background as a classical pianist. The soundtrack is available through Bandcamp, and a vinyl release as well as a book of sheet music are also planned.

Early in her musical career, in the ‘90s, Diana Krall played a regular gig on Saturday evenings in Boston. When she drove down to New York City on Sunday mornings, she’d plan the trip so she could get close enough to hear the FM signal of WBGO in time to hear Singers Unlimited. She’s been hearing herself playing piano and singing ever since on WBGO. Diana Krall performs live in-studio, and speaks with Michael Bourne. Recorded 5/5/17. Nowadays, she can listen to wbgo.org during her travels around the world or in her hometown, Nanaimo, British Columbia. “I listen to you all the time,” she said when she came in for a recent session with a killer band, featuring frequent quartet-mate Anthony Wilson on guitar, along with bassist Robert Hurst, drummer Karriem Riggins and violinist Stuart Duncan.

The first hearing of a state commission to implement a public campaign finance system for New York’s elections was overshadowed by the issue of whether to end fusion voting, which allows candidates to run on multiple ballot lines. Critics of the proposal say Governor Cuomo wants to strike against a left leaning party that he’s been feuding with, something the governor denies.

Illinois U.S. Representative Cheri Bustos is pushing for expansion of health insurance enrollment during the Covid-19 pandemic. She made the comment after leaving a House hearing Wednesday regarding the successor to the CARES Act. “I believe it’s shortsighted of the Trump administration not to reopen the enrollment period for the Affordable Care Act when we’re in the middle of a worldwide pandemic.” Bustos cosponsored a bill in April that would create this very enrollment period. It is currently in committee. Also after the hearing, she said a key area that needs to be included in future legislation is contact tracing of people who have been exposed to an individual with COVID-19. “If we don’t get a plan figured out for that, not just the money, but a plan, it is going to be very difficult for our country to get back into some state of normalcy," she said. "And that was clear in the hearing that we held today that that will be absolutely critical for our nation’s future.” Bustos also

For the first time in a decade Congress will hold a hearing Wednesday on the subject of reparations for the descendants of slaves in the United States, a topic that has gained traction in the run-up to the 2020 elections. The hearing is set for June 19, also known as "Juneteenth," the day when in 1865 former enslaved people in Texas first learned that they had been emancipated two years earlier. The House Judiciary Subcommittee on the Constitution, Civil Rights and Civil Liberties is holding the hearing on H.R. 40 , which calls for a commission to "study and develop reparation proposals for African-Americans," including a formal apology by the U.S. government "for the perpetration of gross human rights violations and crimes against humanity on African slaves and their descendants." The hearing is scheduled to feature testimony from author Ta-Nehisi Coates, whose article "The Case for Reparations," published by The Atlantic magazine in 2014, is widely credited with re-igniting the

With 1.4 billion people, making it one of the world’s most populous nations, India is hearing the full and everlasting gospel being faithfully proclaimed daily, thanks to the gifts of precious supporters like you, who make the work of Amazing Facts International possible.

Our frontline work in India is being conducted by a dedicated team whose members must remain anonymous to continue their work. India is a vast nation with a large population, making the opportunity to preach great, but religious prejudice against Christianity and open public evangelism requires special discretion, especially when reporting on the ministry’s day-to-day outreach efforts.

A careless step could create overwhelming disruptions for our workers at a crucial time, as it has done for other Christian ministries in the nation in recent years.

However, despite an outright ban on open evangelism in many parts of India, Amazing Facts television messages still air on seven Christian television channels across the nation—in English, Hindi, Tamil, and Telugu. Plans are now underway to add a Bengali-language broadcast and to reach Muslim areas of India and neighboring Bangladesh. Also in the works is reaching those who speak Nepali. Moreover, our work in India will help us reach the tiny Himalayan kingdom of Bhutan, whose language is Dzongkha.

There has been an encouraging response: 320 Bible Study Guides have been mailed out by our team, and the first lessons completed by seekers of Bible truth are now coming in. The 27 lessons in our Bible School course will also soon be converted into a digital format for use on mobile devices. At the same time, the Amazing Adventure Bible Guides, designed for children, have also been distributed with a positive reception.

Changing Lives

Most gratifying are the personal testimonies of those reached by the message. During the first three months of 2020, we received 252 requests for free literature. One man from Punjab expressed gratitude for the Christian resources he received, saying that since the deaths of his wife and their only son during the past two years, he was cut off from his relatives and contemplated suicide. But with the new hope he received from our broadcasts, he felt God still had a plan for his life. This man is now distributing Amazing Facts literature to his neighbors.

And a woman in her 70s is going to Christian pastors in her area and urging them to read Amazing Facts literature so that they, too, can understand and share the three angels’ messages with others. She considers this task her biggest goal in the remaining years of her life.

Thanks to the labor of a small, dedicated team of workers, Amazing Facts International is bringing the good news of Jesus and His soon return to many important centers in India and neighboring lands. But there is much more difficult work to be done. That’s why we are so grateful for your prayer support and gifts. Because of you, a co-laborer and part of our ministry family, we’re able to reach this crucial corner of the world!
