AbstractWe have investigated the case of a coronal mass ejection that was eroded by the fast wind of a coronal hole in the interplanetary medium. When a solar ejection takes place close to a coronal hole, the flux rope magnetic topology of the coronal mass ejection (CME) may become misshapen at 1 AU as a result of the interaction. Detailed analysis of this event reveals erosion of the interplanetary coronal mass ejection (ICME) magnetic field. In this communication, we study the photospheric magnetic roots of the coronal hole and the coronal mass ejection area with HMI/SDO magnetograms to define their magnetic characteristics.

With shape memory function of new smart material, the magnetic control properties of magnetic shape memory alloy could be used to fabricate intelligent actuators for vibration control of structures. In order to study its magnetic properties, this text selected Ni53Mn25Ga22 as the material for the research and development of actuator drive, And two MSMA test specimens were prepared for the experimental study under the coupled action of the temperature, preload pressure and magnetic field. The results showed that the strain of MSMA induced by magnetic field decreased with the increase of the preload pressure at constant magnetic field. The deformation performance was best when the magnetic induction intensity was about 0.5T. And the constitutive relations were fitted for the actuator production to lay the foundation for later.

The split-drain magnetic field effect transistor (MAGFET) based on nanopolysilicon thin film transistor (TFT) is fabricated on <100> high resistivity silicon substrates by (complementary metal oxide semiconductor) CMOS technology in this paper. It contains source (S), drain1 (D1), drain2 (D2) and gate (G), and adopts nanopolysilicon thin films and nanopolysilicon/high resistivity silicon heterojunction interfaces as the magnetic field sensing layers. The influence of the channel size and shapes on the transistor, are studied to further improve its magnetic sensitivity. When the ratio of channel length and width (L/W) of MAGFET is 80 μm/160 μm, VDS=5.0 V, the MAGFET with convex channel has higher magnetic sensitivity than the rectangle and concave, the absolute current magnetic sensitivity SI and the absolute voltage magnetic sensitivity SV of the proposed sensor reach the maximum values, and are 0.021 mA/T and 55 mV/T, respectively.

The results of studies of the temperature dependences of the magnetic properties and magnetic field behavior of thin-film three-layer Co/Gd/Co system, obtained by ion-plasma magnetron sputtering, are present. The thickness of the cobalt layers is 5.0 nm, and the thickness of the Gd layers, tGd, varies from 3.0 to 10.0 nm. The bulk magnetic characteristics of the samples are measured on a vibrating magnetometer at the external magnetic field oriented parallel to the plane of the samples. The influence of the temperature and Gd thickness on the shape of the hysteresis loops, the values of the magnetic moment m and coercive force are discovered. In particular, with the temperature changes from 100 to 300 K, the decrease of the coercive force is observed. At a temperature above 150 K, magnetic moment increases. With increasing thickness of gadolinium, the value of m decreases.

Introduction Despite many studies on cell division, formation and treatment of cancer (Ca), there is not full explication of aging and death of cells. Everything in the Earth’s magnetic field (EMF) has paramagnetic and ferromagnetic characteristics. Hence tissue cells and organs have magnetic characteristics (Mc). This paper shows that EMF is a factor that impacts cell division. Anomalous magnetic fields (AMF) and unnatural EMF contributes to continuous cell division that causes cancer. Moreover, it shows that the magnetic characteristics of the nuclei, organelles and substances are tightly related to the metabolism of the cells. The article also explains when the immune system works the best, why it fails in preventing the formation of cancerous cells, and how aging reduces the defense of the organism against intruders. Results EMF influences all parts of the cells magnetic characteristics, which in turn impact metabolism. The sequences of the nucleotides in the construction of DNA and RNA match only by magnetic code. EMF impacts the process of crossing over which causes polymorphism and contributes to the evolution. A factor that stimulates cell division is EMF which boosts the metabolism and the immune system. All manifestations of aging are clearly explained by magnetic properties of cells. Intermolecular magnetic force (Mf) in cell varies because they depend on the number of divisions and temperature. With each division, telomeres lose 100-200 nucleotides which reduce the nucleus Mf and metabolism in the cells. The immune system weakens, because of the impact of Mf. Conclusion Natural EMF is a factor that infulences cell division. Magnetic characteristics of nuclei, organelles and substances enable metabolism in cell. EMF and magnetic characteristics of cells have a decisive contribution to the world’s evolutionary process. During cell division, Mf are decreasing in nucleus so less water enters the cell, resulting in accumulation of toxins. The functions of organs and particularly hormonal activity are declining, which leads to deposition of calcium salts in cartilage (in and around chondrocytes), and lower function of the immune system. All of the above are a manifestation of aging

Abstract. The occurrence rate of linear and pseudo magnetic holes has been determined during MESSENGER's cruise phase starting from Earth (2005) and arriving at Mercury (2011). It is shown that the occurrence rate of linear magnetic holes, defined as a maximum of 10° rotation of the magnetic field over the hole, slowly decreases from Mercury to Earth. The pseudo magnetic holes, defined as a rotation between 10° and 45° over the hole, have mostly a constant occurrence rate, with a slight increase in front of the Earth and a decrease around the Earth. The width and depth of these structures seem to strongly differ depending on whether they are inside or outside of Venus's orbit.

Abstract. We analyze two magnetic clouds (MCs) observed in different points of the heliosphere. The main aim of the present study is to provide a link between the different aspects of this phenomenon, starting with information on the origins of the MCs at the Sun and following by the analysis of in-situ observations at 1 AU and at Ulysses. The candidate source regions were identified in SOHO/EIT and SOHO/MDI observations. They were correlated with H-α images that were obtained from ground-based observatories. Hints on the internal magnetic field configuration of the associated coronal mass ejections are obtained from LASCO C2 images. In interplanetary space, magnetic and plasma moments of the distribution function of plasma species (ACE/Ulysses) were analyzed together with information on the plasma composition, and the results were compared between both spacecraft in order to understand how these structures interact and evolve in their cruise from the Sun to 5 AU. Additionally, estimates of global magnitudes of magnetic fluxes and helicity were obtained from magnetic field models applied to the data in interplanetary space. We have found that these magnetic characteristics were well kept from their solar source, up to 5 AU where Ulysses provided valuable information which, together with that obtained from ACE, can help to reinforce the correct matching of solar events and their interplanetary counterparts.
