 also confirmed in our simulations when the spin fluctuation is suppressed by introducing additional hard-axis anisotropy KyS 2 y in the model. Fig. 5(d) shows the simulated FM wall velocity as a function of Ky. With the increase of Ky, the spin fluctuation is gradually suppressed, and the velocity increases to a saturation value approximates to that of the AFM wall.

D. Brief discussion
While we are pursuing the faster, the smaller, the denser for spintronic devices, the domain wall motion efficiently driven by low energy-consuming can be always the core concern for spintronic study. Thus, finding new energy-saving methods of controlling the domain walls in antiferromagnet, regardless of it is metal or insulator, is still of great importance for future applications.
In this work, anisotropy gradient has been clearly revealed to efficiently drive the AFM domain wall motion. Experimentally, anisotropy gradient could be easily obtained through tuning electric voltage on particular heterostructures, and drive the AFM domain wall motion at a considerable speed. Specifically, for ΔK/Kc = 1 × 10 -4 a -1 and  = 0.002, the speed of the wall for NiO with the exchange stiffness A ≈ 5 × 10 -13 J/m, a ≈ 4.2 Å, s ≈ 1.7 B (B is the Bohr magneton) is estimated to be ~ 100 m/s. More importantly, the proposed modulating method is expected to be more energy-saving and with less Joule heat, comparing with those electric current driving methods. Thus, our work unveils a promising method of controlling AFM wall, and does provide useful information for future spintronic applications.

IV. Conclusion
In summary, we have studied the AFM wall motion under the anisotropy gradient based on the one-dimensional model. The domain wall velocity depending on the gradient magnitude and intrinsic physical parameters are simulated based on the LLG equation and also calculated theoretically based on the energy dissipation theorem. The domain wall structure is rather robust for small gradient and moves at a constant velocity, while accelerates for large gradient due to the enlargement of the domain wall width during its motion. The domain wall mobility is independent of the lattice dimension and wall type (180° or 90°), while the mobility is enhanced by the DM interaction. Moreover, the physical mechanism of the AFM wall dynamics faster than FM wall dynamics is also qualitatively explained. This work unveils a promising strategy for controlling the AFM domain walls, benefiting to future spintronic applications.---

![](//matthewbaykenney.github.io/cmac-formlabs/images/meshmixer.jpg)Employee burnout is an issue that spans industries, but it’s hard to argue that anyone is feeling the effects of work-related stress more than those in healthcare. Things have gotten so bad over the past few years that about 18% of healthcare workers left their jobs between February 2020 and September 2021.
Hospital staff nurses have had a particularly rough go of it. Overworked, underresourced, and sometimes underpaid, quite a few have decided to leave hospital employment behind: In 2020, the nurse turnover rate was nearly 19%, and the cost of nurse turnover is nothing to sneeze at. Each time a hospital loses one of its bedside nurses, according to a survey of hospital leaders, it forfeits an average of $40,000 — resulting in a net loss of up to $6.5 million annually.
Some disenchanted nurses have left the industry altogether. Others have turned to cross-country travel nursing gigs, which can pay them two to four times more than they would earn as a full-time nurse due to the inflow of federal funding hospitals have received since the start of the COVID-19 pandemic.
Unfortunately, this trend has set off a vicious cycle: Staff-strapped hospitals spend a fortune to bring on cross-country travel nurses, which stunts their ability to increase the pay of their full-time nurses. As a result, staff nurse turnover continues to grow. This drives down the hospital’s nurse supply and increases its demand for travel nurses. Repeat the cycle.
This fact hasn’t been lost on travel nursing agencies, either: The pay rate for travel nurses rose 67% between 2020 and 2022. Regardless of the source of this staffing shortage in hospitals, this fragmented nursing workforce is causing all sorts of problems — particularly on the patient side.
Representing nearly one-third of all hospital staff, nurses are some of the most critical players in the healthcare system. Acute care nurses like those in the emergency department are particularly essential — not only do they triage and care for patients, but they also handle a variety of administrative and billing-related tasks.
Emergency department staffing shortages and the resulting nursing burnout have caused some unwelcome problems. When wires get crossed in a busy emergency department, for instance, patients can end up getting double-billed (which, by the way, is another reason you need to understand how to read your medical bills). Burned-out healthcare workers are also more likely to make mistakes that could compromise patient safety.
While the quality of care offered by travel nurses is high, bringing them on to fill gaps doesn’t necessarily solve this problem. Contract agencies sell hospitals on their ability to streamline recruitment and credentialing of emergency department staff. This might help alleviate staffing issues, but it has consequences.
Hospitals that augment their full-time staff with contract workers get the help they need, but it can also create tension between full-time and cross-country travel nurses. In most cases, these full-time nurses are working their tails off alongside travelers who are making significantly more money than them. While there are certainly downsides to being a travel nurse, they also tend to enjoy more flexibility and fewer workplace obligations than their full-time counterparts.
And because travel nurses are not as familiar with the inner workings of the hospitals where they fill gaps, staff nurses are also expected to share their institutional knowledge with these temporary colleagues who are earning far better pay. This kind of dynamic is a breeding ground for intra-workplace resentment.
The influx of travel nurses in hospitals has become a Band-Aid solution for larger issues within the healthcare system. It’s unsustainable for hospitals to continue to pay outsize travel nurse pay while shortchanging their full-time personnel. Instead, hospitals need to implement longer-term solutions to reduce nurse turnover.
One way hospital leadership can reduce nurse turnover is by offering a truly robust benefits package. While salary is certainly one aspect of that, health benefits are another key factor. According to the Society for Human Resource Management, nearly half of American workers say the quality of their health coverage is an important factor in deciding whether to stay at their jobs. And by adding a benefit like Paytient to the mix, you can lower turnover by making your benefits package even stronger.
It’s perhaps the understatement of the year to say that nurses are burned out. Hospitals are losing staff nurses in droves, and they’re turning to travel nurses to plug those gaps. But this isn’t an ideal long-term solution. Instead, hospitals should focus on reinvesting in their existing staff members by offering benefits that are hard to leave.Larry Sanders, older brother of United States presidential hopeful Bernie Sanders, at his home in Oxford.
At the age of 84, Larry Sanders isn’t worried about younger brother Bernie’s staying power in the US Democratic Party’s nomination process, not least because “78 sounds young to me”.
A genteel Oxford-based Green Party representative who came to the UK in the 1960s, Larry still retains the Brooklyn accent and speaking mannerisms that his younger sibling has made so famous.
Speaking to Jewish News this week, Larry set out to reassure Jews both here and in the United States that Bernie – or Bernard as he prefers – would be in any way a danger to Israel if elected US president later this year.
Q. What’s it like watching Bernard doing so well?
It’s amazing. Ever since he hit the big time, getting audiences of 30,000, it’s just impossible to describe. I do a double-take every time. This year is of historical significance, because he had a really strong chance to become president, at a time when you have the rise of the far-right, the destruction of the planet, and the success of Trump. It’s frightening.
It’s not just European. You see what Trump and many of his followers believe. There’s a not insignificant white nationalist movement in the US, antisemitism is on the rise – we’ve had all those deaths, add to that Trump’s comments about Muslims… It is sheer out-and-out racism and not innocent. He’s playing with fire. You don’t need to be Jewish to be worried. Trump’s rhetoric is anti-immigrant, anti-other, and it’s very powerful. Hitler showed us how people are capable of loving our fellow but also hating anyone who isn’t our fellow.
Q. Does your younger brother ever call his older brother for advice?
No, sadly not. For years we talked on the phone every Sunday but all that’s gone away with the campaign.

Q. What would your advice be?
Follow your instincts. He knows what he’s doing and is very disciplined. He also knows what lurks if he doesn’t win.
Q. Some people have suggested his age could count against him?
From my point of view, 78
