Non-volatile memory device having vertical structure and method of operating the same

Abstract: A non-volatile memory device having a vertical structure includes a NAND string having a vertical structure. The NAND string includes a plurality of memory cells, and at least one pair of first selection transistors arranged to be adjacent to a first end of the plurality of memory cells. A plurality of word lines are coupled to the plurality of memory cells of the NAND string. A first selection line is commonly connected to the at least one pair of first selection transistors of the NAND string.

The Design of Dual Emitting Cores for Green Thermally Activated Delayed Fluorescent Materials

Abstract: Dual emitting cores for thermally activated delayed fluorescent (TADF) emitters were developed. Relative to the corresponding TADF emitter with a single emitting core the TADF emitter with a dual emitting core, 3,3′,5,5′-tetra(carbazol-9-yl)-[1,1′-biphenyl]-2,2′,6,6′-tetracarbonitrile, showed enhanced light absorption accompanied by a high photoluminescence quantum yield. The quantum and power efficiencies of the TADF devices were enhanced by the dual emitting cores.

Antenna device and electronic apparatus having the same

Abstract: An antenna device is provided. The antenna device may include a conductive radiator pattern formed on one surface of a dielectric substrate, an artificial magnetic conductor layer including at least one unit cell formed on the other surface of the dielectric substrate, and a shorting pin connected to the unit cell. The artificial magnetic conductor layer may be configured to form an induction current of the same phase with regard to a signal current flowing through the conductive radiator pattern.

Parthanatos Mediates AIMP2 Activated Age Dependent Dopaminergic Neuronal Loss

Abstract: In this study, the authors show that overexpression/accumulation of the parkin substrate AIMP2 induces an age-dependent degeneration of dopaminergic neurons and results in motor dysfunction. This effect is dependent on AIMP2-induced activation of PARP1, which, in turn, induces cell death via parthanatos.

Apparatus and method for matching harmonics

Abstract: An apparatus of a power amplifier is provided. The apparatus includes an input boosting circuit configured to match a second harmonic input signal using a harmonic control circuit of an input stage to maximize an efficiency and an output power, a die cell configured to receive and amplify an output signal of the input boosting circuit, and an output boosting circuit configured to receive an output signal of the die cell and to match a second harmonic output signal of the output signal of the die cell using a harmonic control circuit of an output stage to maximize the efficiency and the output power.
