CMOS current-reversing circuit
2018 7th International Symposium on Next Generation Electronics (ISNE), 2018In this paper, a CMOS current-reversing circuit has been proposed. The layout of the proposed circuit has been made by using the N-well 0.35μm 2p4m process parameters. According to the post-layout simulation results, as the supply voltage is set to 2V, the input current range of the proposed current-reversing circuit can be ± 150 μA, the corresponding ...

Current-induced precessional magnetization reversal
Applied Physics Letters, 2003We report magnetization reversal in microscopic current-in-plane spin valves by ultrashort current pulses through the device. Current densities of the order of 1011 A/m2 with pulse durations as short as 120 ps reliably and reversibly switch the cell’s free-layer magnetization. Variations of the pulse parameters reveal the full signature of precessional

Reversal currents in dielectric liquids
Proceedings of 1995 International Symposium on Electrical Insulating Materials, 2002A review of data on the investigation of reversal currents in dielectric liquids shows that the shape of the reversal characteristic depends on the nature of the liquid and the impurities in it, the field strength, the time interval, the time repetition, the electrode gap, the temperature etc.

Deterministic Ratchets, Circle Maps, and Current Reversals
Physical Review Letters, 2006In this work we transform the deterministic dynamics of an overdamped tilting ratchet into a discrete dynamical map by looking stroboscopically at the continuous motion originally ruled by differential equations. We show that, for the simple and widely used case of periodic dichotomous driving forces, the resulting discrete map belongs to the class of ...

Current Controversies in Reverse Total Shoulder Arthroplasty
JBJS Reviews, 2016➢ Reverse total shoulder arthroplasty can restore forward elevation in pseudoparalytic shoulders, can reduce pain, and can increase quality of life for patients; however, there are a number of issues with regard to the design and ideal implantation technique of reverse total shoulder arthroplasties that remain controversial.➢

Reversed nested Miller compensation with current follower
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002The reversed nested-Miller compensation technique is reviewed by using a simple design-oriented approach. A single current follower is also exploited to provide right-half-plane zero removal while allowing wide band and preserving output swing. Thanks to the small compensation capacitors employed, the approach is suited for integration.

Plasma Current Profile During Current Reversal in a Tokamak
Chinese Physics Letters, 1999Alternating current operation with one full cycle and a current level of 2.5 kA have been achieved in the CT-6B tokamak. The poloidal magnetic field in the plasma is measured with two internal magnetic probes in repeated discharges. The current distribution is reconstructed with an inversion algorithm.

Current reversible contraceptive methods: a global perspective
International Journal of Gynecology & Obstetrics, 1998AbstractSince the 1960's there have been important gains in the efforts to make the benefits of family planning accessible to people around the world. However, prevalence of contraceptive use is still low in some areas, especially in sub‐Saharan Africa.
