A New Design of Metamaterials for SAR Reduction
Measurement Science Review, 2013 The purpose of this paper is to calculate the reduction of specific absorption rate (SAR) with a new design of square metamaterials (SMMs). The finite-difference time-domain (FDTD) method with lossy-Drude model is adopted in this analysis.

Future Directions for Transuranic Single Molecule Magnets
Inorganics, 2018 Single Molecule Magnets (SMMs) based on transition metals and rare earths have been the object of considerable attention for the past 25 years. These systems exhibit slow relaxation of the magnetization, arising from a sizeable anisotropy barrier, and ...

, 2011 We study the interplay of the Kondo effect and spin-polarized tunneling in a class of systems exhibiting uniaxial magnetic anisotropy, such as magnetic molecules, magnetic adatoms, or quantum dots coupled to a single localized magnetic moment.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Spin Polarized Transport Through a Single-Molecule Magnet: Current-Induced Magnetic Switching
, 2007 Magnetic switching of a single-molecule magnet (SMM) due to spin-polarized current is investigated theoretically. The charge transfer between the electrodes takes place via the lowest unoccupied molecular orbital (LUMO) of the SMM.

HIV Medicine, EarlyView.Abstract Introduction Long‐acting injectable antiretroviral therapy (ART) with Cabotegravir (CAB) and Rilpivirine (RPV) offers an alternative to daily oral regimens, improving adherence and patient satisfaction. However, its impact on body composition and metabolism remains underexplored.

Single molecule magnet’s (SMM) effects on antiferromagnet-based magnetic tunnel junction
AIP AdvancesSingle-molecule magnets (SMMs) are pivotal in molecular spintronics, showing unique quantum behaviors that can advance spin-based technologies. By incorporating SMMs into magnetic tunnel junctions (MTJs), new possibilities emerge for low-power, energy ...

What Drives Investors' Portfolio Choices? Separating Risk Preferences from Frictions
The Journal of Finance, EarlyView.ABSTRACT We study the role of risk preferences and frictions in portfolio choice using variation in 401(k) default options. Patterns of active choice in response to different default funds imply that, absent participation frictions, 94% of investors prefer holding stocks, with an equity share of retirement wealth declining with age—patterns markedly ...
