Abstract: Non-volatile resistance change memories, systems, arrangements and associated methods are implemented in a variety of embodiments. According to one embodiment, a memory cell having two sections with outwardly-facing portions, the outwardly-facing portions electrically coupled to electrodes is implemented. The memory cell has an ionic barrier between the two sections. The two sections and the ionic barrier facilitate movement of ions from one of the two sections to the other of the two sections in response to a first voltage differential across the outwardly-facing portions. The two sections and the ionic barrier diminish movement of ions from the one of the two sections to the other of the two sections in response to another voltage differential across the outwardly-facing portions.

Abstract: An elongated shaft has a shock-absorbing core, a fiber-reinforced durable plastic outer skin encasing the core, and an elongated stiffening member encased within the core. The elongated stiffening member may be a spar or a hollow tube. If it is a hollow tube, the tube may contain a weight that moves along the inside of the tube as the shaft is swung. The shaft also has a way to attach athletic equipment, such as a lacrosse head frame and net, to one end.

Abstract: The method for testing of substances for hormonal effects, especially for androgenic or anti-androgenic effects, includes exposing cells transfected with two vectors to the substances, wherein one vector contains a DNA, which codes for a nuclear receptor protein, or a fragment thereof, especially a human nuclear receptor protein, or a fragment thereof, and the other vector contains a DNA, which codes for the HSRNAAM co-modulator, or a fragment thereof; and measuring transcription activity, which the nuclear receptor protein, or its fragment, activates or releases in the presence of the HSRNAAM co-modulator, or its fragment, and/or measuring the influence of the substance on the interaction between the nuclear receptor protein, or its fragment, and the HSRNAAM co-modulator, or its fragment, by protein-protein interaction or by protein-protein-DNA interaction. Also a method for determining interference in the co-modulation mechanism between androgen receptor protein and HSRNAAM co-modulator is described.

Abstract: The invention relates to a memory element comprised of an electrode (2), of a ferroelectric layer (3), which is adjacent thereto, of a layer (4), which is made of a non-ferroelectric material and which is adjacent to said ferroelectric layer (3), and of an electrode (5), which is made of a non-ferroelectric material and which is adjacent to layer (4). The electric resistance of the ferroelectric layer and of the non-ferroelectric layer are preferably low. The invention also relates to a method for electronically storing information by writing an item of information into a memory element of the aforementioned type by aligning a polarization in a polarizable layer, and the information is read by determining the polarizing direction by measuring resistance. This renders a particularly fast remanent storage of electronic data possible.

Further a method for determining interference in the co-modulation mechanism between androgen receptor protein and FOXG1C co-modulator is described.
