High-Energy YB-Doped Femtosecond Fiber Lasers
… phase shift, by replacing the short high-doped Yb3+ fiber with a long low-doped one. This results in an increase of the peak power by a factor that depends on the ratio between the gain coefficient of the high- and low-doped Yb3+ fiber. The length of the nonlinear section is kept unchanged by …

Search for non-yrast states in ¹⁶°Yb
… non-yrast states of the even-even nucleus ¹⁶⁰Yb populated through the electron capture or β⁺-decay of ¹⁶⁰Lu. The radioactive ¹⁶⁰Lu source was created through the heavy-io fusion evaporation reaction ¹⁴⁴Sm(¹⁹F,3n) at a beam energy of 85 MeV. Both ϒ-ϒ coincidences and single ϒ rays were detected …

Herstellung monoklonaler Antikörper gegen YB-1 und Charakterisierung ihrer Bindungseigenschaften
Y-box protein-1 (YB-1) belongs to the cold shock protein family. Members of this family are highly conserved in evolution and fulfill numerous functions in gene regulation and mRNA translation. Here, we have successfully generated six distinct anti-YB-1 monoclonal antibodies by immunizing mice with …

Towards spin squeezed ¹⁷¹Yb atomic clock beyond the standard quantum limit
… of the ground state Zeeman sublevels of 171Yb, two different methods are utilized to perform a spin squeezing via coupling to 6s6p3P1 excited state. One method is measurement-based squeezing, which gave 2.1 dB of spin squeezing. The latter method, cavity feedback squeezing, achieved 8.6 dB …

Loading a planar RF Paul Trap from a cold Yb⁺ source
… frequency, three-rod Paul Trap, loaded with Yb+ ions that have been photoionized from a source of neutral atoms, which were cooled in a magneto-optical trap. Planar ion traps have only recently been successfully loaded[1], and never from a cold ion source. Additionally, ionizing directly from …

Identifizierung und Kartierung von nukleären Import- und Exportsignalmotiven innerhalb des Y-box-bindenden Proteins-1 (YB-1)
Y-box Protein-1 (YB-1) is a multifunctional protein, which binds to DNA and RNA thereby influencing transcription and transplation. YB-1 consists of three domains: the N-terminal glycine-rich sequence, the cold shock domain (CSD) and the C-terminal domain. The latter contains alternating acidic and …
