Niimi, Y., Matsui, T., Kambara, H., Tagami, K., Tsukada, M., Fukuyama, Hiroshi
We measured the electronic local density of states (LDOS) of graphite surfaces near monoatomic step edges, which consist of either the zigzag or armchair edge, with the scanning tunneling microscopy...
STS Observations of Landau Levels at Graphite Surfaces (2004)
Matsui, T., Kambara, H., Niimi, Y., Tagami, K., Tsukada, M., Fukuyama, Hiroshi
Scanning tunneling spectroscopy measurements were made on surfaces of two different kinds of graphite samples, Kish graphite and highly oriented pyrolytic graphite (HOPG), at very low temperatures...
Scanning tunneling microscopy and spectroscopy studies of graphite edges (2004)
Niimi, Y., Matsui, T., Kambara, H., Tagami, K., Tsukada, M., Fukuyama, Hiroshi
We studied experimentally and theoretically the electronic local density of states (LDOS) near single step edges at the surface of exfoliated graphite. In scanning tunneling microscopy measurements,...
ADSL analog front-end design for testability (2002)
Bresch, M., Hosticka, B.J., Klein, B., Kokozinski, R., Teßmann, D., Tagami, K., ...
Das in diesem Beitrag vorgestellte ADSL Analog Front-End (AFE) ist ein besonderes Design für gute Testbarkeit. Der Chip läßt sich durch externe Signale für den Test beliebiger Komponenten...
A highly flexible evaluation system for telecommunication analog front-ends (2001)
Bresch, M., Hammerschmidt, D., Hosticka, B.J., Kemmerling, M., Klein, B., Kokozinski, R., ...
As technological progress leads to increasing data transmission rates, use of digital transmission is inevitable. However, since analog waveforms are involved in digital transmission, analog...
A low-voltage low-power 0.25 µm CMOS ADSL analog front-end IC (2000)
Kokozinski, R., Bresch, M., Hammerschmidt, D., Hesener, M., Hosticka, B.J., Kemna, A., ...
A 0.12 µm 2.5V CMOS analog front-end IC for an ADSL system is presented. The IC contains all analog functions including gain-controlled transmit and receive amplifiers, highly linear continuous-time...
Increased natural killer resistance to cyclosporine A by continuous doses of dexamethasone in rats.
Kamio, E, Sakamoto, Y, Kimura, T, Takakuwa, H, Sakurai, M, Hosokawa, J I, ...
There is a controversy on the effects of physiological levels of glucocorticoids on natural killer (NK) cytotoxity. Therefore, the effects of exogenously administered dexamethasone on NK cytotoxity...
