The present invention relates to devices and systems that alter intracranial compliance, cerebral blood flow and/or intracranial pressure pulsatility/waveform by oscillating the contraction and expansion of a compressible composition within the cranial or spinal cavities such that they increase intracranial capacity. The contraction and expansion of the compressible composition in the oscillating compliance devices can be due to an individual's intracranial pressure, the result of the expansion and compression of a reservoir which is mediated by the contractility of the heart or driven by a pump gaited to a biorhythm. The invention also relates to methods for protecting an individual's brain from abnormal arterial pulsations and for altering an individual's cerebral blood flow using the devices and systems of the invention. The oscillating compliance devices can be used to treat several diseases and/or conditions characterized by altered/abnormal intracranial compliance, cerebral blood flow and/or intracranial pressure pulsatility/waveform, including hydrocephalus, stroke, dementia and migraine headaches, vasospasms, congestive heart failure, cardiopulmonary bypass or carotid endarterectomy.

A welding process, such as a GMA welding process, employs a consumable electrode with the consumable electrode being oscillated back and forth over the surface of an object to which welding material is to be applied or across the gap between two pieces of metal to be welded together. At the ends of the swings of the consumable electrode an impact force is applied to the consumable electrode to interrupt its movement, thereby causing molten metal at the end of the consumable electrode from which the arc is struck to be impelled therefrom.

Disclosed is an apparatus and method for generating energy through oscillatory motion requiring little input. Oscillatory motion is generated using a substantially circular trough containing a liquid, inflatable bags positioned below the trough and a movable weight. The trough is pivotally connected to a central point about which it oscillates. Sustained oscillatory motion is encouraged by inflating and deflating the bags in coordination with the movable weight within the trough and a biased member upon which the bags reside. The oscillatory motion may be captured and transferred to rotary motion which may be used to drive a generator.

A loop filter with an active discrete-level loop filter capacitor can be used in a VCO (such as for CDR). A loop filter capacitor function is simulated by sensing input loop filter current (such as with a current mirror and source follower in the input leg), and forcing back a loop filter (VCO) control voltage. Loop filter voltage control is provided using a VDAC with a discrete-level VDAC feedback voltage, incremented/decremented based on the sensed loop filter current. In one embodiment, the VDAC voltage is provided as the non-inverting input to an amplifier, with the inverting input providing the control voltage, forced to the VDAC feedback voltage. The VDAC feedback voltage can be provided by increment/decrement comparators based on a voltage deviation on a C2 capacitor (from a reference voltage) that receives the sensed loop filter current (effectively multiplying the C2 capacitance to provide a simulated loop filter capacitance).

Various embodiments mitigate the risk of frequency-lock in systems having multiple resonators by dynamically changing the frequency at which at least one of the resonators is driven. More particularly, the drive frequency of at least one of the resonators is changed often enough that the multiple resonators do not have time to achieve frequency lock. Changes in the oscillation of the resonators may be analyzed to determine, for example, acceleration of such systems. Some embodiments implement self-test by assessing expected performance of a system with toggling drive frequencies. More particularly, some embodiments implement self-test by artificially inducing displacement of a movable member of a system.

It’s a matter of fact that between 1840 and 1882 there were eight assassination attempts on the life of Queen Victoria, but in his suspenseful novel “The Darwin Affair,” Tim Mason adds a ninth, in 1860, and makes the target Prince Albert. The date is important: it’s just months after the publication of Charles Darwin’s “On the Origin of Species” and concomitant with the Oxford University Museum debate on evolution featuring those famous antagonists – biologist and anthropologist Thomas Huxley and Anglican Bishop Samuel Wilberforce. Prince Albert wants to give Darwin a knighthood. No way say fierce evolution deniers in Parliament and powerful members of the clergy, and so they conscript a sinister anti-evolutionist to kill the prince and thus head off what would otherwise be seen as royal approval of a theory that threatens The Great Chain of Being: the way things are, have been, and must be forever. Little do they know that their hired man, the wraith-like creature with the disturbing

Attorneys for Rick Bright, the government scientist who said he had been reassigned and subsequently filed a whistleblower complaint , say a government watchdog agrees that he should be reinstated to his post. Bright was serving as director of the Biomedical Advanced Research and Development Authority, which is working on a vaccine to combat the coronavirus. He said he was ousted from the position last month because he wanted to spend money on safe and vetted treatments for COVID-19 — not on ones without "scientific merit," such as hydroxychloroquine, the anti-malarial drug that President Trump and others had been touting. Trump on Wednesday called Bright "a disgruntled employee who's trying to help the Democrats win an election." Bright's attorneys say that the Office of Special Counsel, which hears whistleblower cases, determined there were "reasonable grounds" to believe that his removal was retaliatory and therefore prohibited. Bright's attorneys say OSC plans to contact the

The disaster movie starts and when bad things start to happen, a scientist always warns the people to change course. But the people never listen. That’s the gist of a mordant Facebook post circulating among scientists as they, along with the rest of us, have watched this frightening scenario play out in real life. The pandemic moved so fast and was so vicious that it’s no mystery why people insisted it couldn’t happen here. After all, we’re not Italy, or China. Scientists knew better, and in January, warned that it was going to happen here. Trump called them alarmist. In February, health experts were sure the virus had been lurking in communities for a while and was spreading fast. Precious weeks passed and the federal government failed to take charge. Against scientists’ advice, Trump urged those with the virus to take an untested drug. What have you got to lose, he said. In the meantime, governors scrambled to prepare hospitals, issue stay-at-home orders, and figure out testing. This

Eighth grader Abby Pike is putting her Christmas present to good use. She received a sewing machine for the holiday last year. And amidst the COVID-19 global pandemic she and her family have spent their days and evenings sewing. So far, they’ve sewed about 700 masks. They’ve used social media to help distribute them to people who need them through donations and sold some as well. “It just brightens my day to see that I’m making an impact,” Pike said. Pike is involved in Edmond’s Cheyenne Middle School’s Family, Career and Community Leaders of America student organization. And she said many of her friends know a little about sewing, however most students her age and even many adults don’t know even how to sew a button on, her teacher Kendall Wildman said. Wildman teaches family and consumer sciences at Cheyenne. Family and Consumer Science teachers have seen a sudden spike in a need for the skills they teach during the COVID-19 pandemic. The need for teaching the subject, which has

Let’s go back to some news you may remember from several years ago. In 2011, two ethnic Chinese men were seen digging up seeds in a cornfield here in Iowa. When approached, they sped away in a hired car. At first, it was a routine report of trespassing. It quickly grew into a long FBI investigation that uncovered a plot by the Chinese agricultural company DBN, to reverse-engineer seed lines belonging to Monsanto and DuPont Pioneer.

My daughter wants to work in wildlife conservation: research, management, and policy. Which degree would be better for a career in wildlife: veterinary (with a big debt) or master's in environmental biology? She planned for years to go to veterinary school, but then was waitlisted at the one offering in-state tuition (still a lot). So she talked herself out of vet school and applied for two masters in ecological biology (or biological ecology, idk) programs in Germany, where tuition is free. She got really excited about those. Then the vet school called and accepted her!

There are big pros and cons to either plan, but she is only 21 and is thinking about the next few years of school. I want her to look beyond that to what she wants to do with her life.
