O-GlcNAc – a posttranslational modification implicated in Alzheimer disease?
(2015-04-22)
O-linked N-acetylglucosamine (O-GlcNAc) is a highly dynamic posttranslational modification which has been found on a myriad of nucleocytoplasmic proteins. O-GlcNAc addition and removal are catalyzed by two conserved enzymes, ......
Counting classes of special polynomials
(2015-04-20)
Most integers are composite and most univariate polynomials over a finite field are reducible. The Prime Number Theorem and a classical result of Gauß count the remaining ones, approximately and exactly.

Suberin biosynthesis in O. sativa: characterisation of a cytochrome P450 monooxygenase
(2015-03-20)
In endodermal and exodermal cell walls of roots the polyester suberin forms a radial diffusion barrier for water, solutes and gases. Depolymerization of this otherwise insoluble lipophilic polymer releases its aliphatic ...
Dnajc22 - a new susceptibility gene for salt-sensitive hypertension
(2015-06-10)
Chaperones of the heat shock (HSP) 70 family mediate elementary funtions in a cell, such as folding, oligomerization, transport, or degradation of proteins. Their function is particularly needed when cells are exposed to ...
Resolving the inner circumstellar disks of T Tauri and Herbig Ae/Be stars with infrared interferometry
(2015-03-20)
Circumstellar disks around young stellar objects (YSO) are a fundamental element of star and planet formation. The inner disk regions of pre-main sequence stars are hot enough for dust sublimation and a rim between dust-free ...
W → τντ Cross Section Measurement and Search for the Standard Model Higgs Boson in the τlep τhad Final State with the ATLAS Detector
(2015-03-13)
Two measurements based on proton-proton collisions recorded with the ATLAS experiment at the LHC with τ leptons and missing transverse energy in the final state are presented.

Algorithmen zur strukturellen Analyse von Musikaufnahmen
(2015-03-10)
Eine sinnvolle Beschreibung von Musik und insbesondere von Musikaufnahmen durch maschinelle Verfahren ist eine große Herausforderung für das junge Forschungsgebiet des Music Information Retrieval. Einige Aspekte der Harmonik ...
Retrieval of cloud and rainwater from ground-based passive microwave observations with the multi-frequency dual-polarized radiometer ADMIRARI
(2015-03-24)
A ground-breaking new-concept multi-wavelength dual-polarized passive microwave radiometer ADMIRARI (ADvanced MIcrowave RAdiometer for Rain Identification) has been developed to perform observations of atmospheric precipitating ...
Untersuchungen zur Regulation und Biosynthese apoplastischer Polyester in höheren Pflanzen
(2015-04-02)
Ziel der vorliegenden Arbeit war die Identifizierung von an der Suberinbiosynthese beteiligten Genen und der Aufklärung ihrer Funktion, um diese in das bestehende Synthe-seschema einordnen zu können. Hierzu wurden durch ...
Understanding social ecological change through palm use and management
(2015-03-31)
As people change their livelihood preferences, they change the way they relate to the natural resources around them. Anticipating and managing these changes, where possible, is a major challenge for sustainable land-use ......
