The transient integral charge control relation—A novel formulation of the currents in a bipolar transistor

Holger Klose, A. Wieder
IEEE Transactions on Electron Devices
1987

The present paper describes the transient integral charge control (TICC) relation. This term designates a formula describing the emitter, base, and collector terminal currents of a bipolar junction… (More)

OBJECTIVE The study was conducted to evaluate the long-term results of homograft reconstruction of the left ventricular outflow tract with a cryopreserved aortic homograft in the presence of aortic… (More)

Surgical management of acute aortic root endocarditis with viable homograft: 13-year experience.

Abraham Charles Yankah, Holger Klose, Rainer Petzina, Michele Musci, Henryk Siniawski, Roland Hetzer
European journal of cardio-thoracic surgery…
2002

OBJECTIVE Cryopreserved homograft valves have been used for acute infective aortic root endocarditis with great success but it is compounded by its availability in all sizes. The long-term clinical… (More)

Geometric mismatch between homograft (allograft) and native aortic root: a 14-year clinical experience.

Abraham Charles Yankah, Holger Klose, Michele Musci, Henryk Siniawski, Roland Hetzer
European journal of cardio-thoracic surgery…
2001

OBJECTIVES We evaluated the effect of homograft/native aortic root geometric matching and mismatching on valve survival and myocardial remodeling. METHODS Between January 1, 1987 and March 2000, a… (More)

Heart valve operations in solid organ recipients: an 18-year single-center experience.

Michele Musci, Charles A Yankah, +4 authors Roland Hetzer
Transplantation
2007

BACKGROUND We retrospectively analyzed the outcome of heart valve operations in solid organ recipients, who were referred for operation to our institution. METHODS Over an 18-year period, 23 heart… (More)

Image reversal of positive photoresist: Characterization and modeling

Holger Klose, R. Sigush, William M. Arden
IEEE Transactions on Electron Devices
1985

We report on an investigation of a so-called image-reversal process where a negative tone image can be obtained with a positive resist. The reversal process is achieved by addition of a base to the… (More)

Borosilicate glass and its applications in bipolar technology

Mauro Bianco, K. Ehinger, B. Hautke, Holger Klose, H. v. Philipsborn
ESSDERC '91: 21st European Solid State Device…
1991

Borosilicate glass (SiOB) and its outdiffusion properties were investigated. The outdiffusion of boron can be controlled by using an intermediate oxide layer. Borosilicate glass can be used to… (More)
