We hypothesize possible new types of forces that would be the result of new types of interactions, static and a slow transient, between objects with related information contents (pattern). Such mechanism could make material composition dependence claimed by Fishbach, et al. in Eotvos type experiments plausible. We carried out experiments by using a high-resolution scale with the following memories: USB-2 flash drives (1-16GB), DVD and CD disks to determine if such an interaction exist/detectable with a scale resolution of 10 microgram with these test objects. We applied zero information, white noise and 1/ f noise type data. Due to the non-reproducible changes of static weight of these memories after changing the information in them, we have not been able to clarify the existence of a reproducible static force between the memory and its environment even though the variations of static weight could possibly be the manifestation of the new type of interaction with changing environment. Interaction between two memories containing the same information was not detected at the given weight resolution. The hypothesis of slow transient interaction is more in line with the observations provided the observed effects are not artifacts. Writing or deleting the information in any of these devices causes peculiar negative weight transients, up to milligrams (mass fraction around 10−5), which is followed by various types of relaxation processes. These relaxations have significantly different dynamics compared to transients observed during cooling after stationary external heating. Interestingly, a USB-1 MP3 player has also developed comparable transient mass loss during playing music, even though its information content was not changed, and its power dissipation and warming-up was much less than that of the USB-2 flash drives. A classical interpretation of the negative weight transients could be absorbed water in hygroscopic components, though comparison of relaxation time constants with air humidity data does not support an obvious explanation. Another classical interpretation with certain contribution is the lifting Bernoulli force caused by the circulation due to convection of the warm air. However, in this case all observed time constants with a device should have been the same unless some hidden parameter causes the observed variations. Thus further studies are warranted to clarify if there is indeed a new force, which is showing up as negative mass at weight measurement when high-density structural information is changed or read out (measured). We estimate that, if the information-based interaction is real, the weight of bodies could be reduced and floating engines could be achieved with several orders of magnitude greater data handling capacities than today's values at the same mass.

Electric energy data acquisition system is the necessary requirement to construct "Marketing" infrastructure and smart grid, change the development mode of the company and grid. To solve the problems of the 230MHz wireless private network of the electric energy data acquisition system, such as low communication rate, fewer access points, low acquisition success rate and poor real-time performance, a new-type data transmission scheme of electric energy data acquisition system is proposed. The key technologies, such as carrier aggregation, software radio, multi-antenna, networking, OFDM, safeguard and other technologies, are discussed. The new-type communication technology based on SGWM in the electric energy data acquisition system is elaborated. The experimental results show that the field application effect of the new-type 230MHz communication key technology based on SGWM in the electric energy data acquisition system is improve the interactivity, real-time instantaneity, reliability of smart grid.. Thus it provides technical support for the popularization of the information bidirectional interaction and construction of smart grid.

A new type of synthetic industrial diamond formed by an explosive shock process has been recently developed by the Du Pont Company. This material consists of a mixture of two basically different forms, as shown in Figure 1: relatively flat and compact aggregates of acicular crystallites, and single crystals in the form of irregular polyhedra with straight edges.Figure 2 is a high magnification micrograph typical for the fibrous aggregates; it shows that they are composed of bundles of crystallites 0.05-0.3 μ long and 0.02 μ. wide. The selected area diffraction diagram (insert in Figure 2) consists of a weak polycrystalline ring pattern and a strong texture pattern with arc reflections. The latter results from crystals having preferred orientation, which shows that in a given particle most fibrils have a similar orientation.

I. IntroductionThermionic electron gun with the Wehnelt grid is popularly used in the electron microscopy and electron beam micro-fabrication. It is well known that this gun could get the ideal brightness caluculated from the Lengumier and Richardson equations under the optimum condition. However, the design and ajustment to the optimum condition is not so easy. The gun has following properties with respect to the Wehnelt bias; (1) The maximum brightness is got only in the optimum bias. (2) In the larger bias than the optimum, the brightness decreases with increasing the bias voltage on account of the space charge effect. (3) In the smaller bias than the optimum, the brightness decreases with bias voltage on account of spreading of the cross over spot due to the aberrations of the electrostatic immersion lens.In the present experiment, a new type electron gun with the electrostatic and electromagnetic lens is designed, and its properties are examined experimentally.

After materials with superconducting temperatures higher than liquid nitrogen have been prepared, more emphasis has been on increasing the current densities (Jc) of high Tc superconductors than finding new materials with higher transition temperatures. Different processing techniques i.e thin films, shock wave processing, neutron radiation etc. have been applied in order to increase Jc. Microstructural studies of compounds thus prepared have shown either a decrease in gram boundaries that act as weak-links or increase in defect structure that act as flux-pinning centers. We have studied shock wave synthesized Tl-Ba-Cu-O and shock wave processed Y-123 superconductors with somewhat different properties compared to those prepared by solid-state reaction. Here we report the defect structures observed in the shock-processed Y-124 superconductors.
