PURPOSE. To describe the retinal dystrophy phenotype associated with mutations in RDH12, the gene encoding a retinoid dehydrogenase/reductase expressed in the photoreceptor cells. METHODS. Sixteen persons from 12 families with pathogenic RDH12 mutations on both alleles were studied. Retinal phenotypes were characterized by ophthalmic examination, including psychophysical and standardized electrophysiological methods and multifocal electroretinography (mfERG). was diagnosed initially as Leber
more » ... genital amaurosis (LCA) or early-onset retinitis pigmentosa. These individuals appeared to share a common clinical picture, independent of the type of mutation, characterized by poor, yet useful visual function in early life, followed by progressive decline due to both rod and cone degeneration. Marked pigmentary retinopathy, including bone spicules in the peripheral retina, was present in all persons older than age 6, and pronounced maculopathy was evident in persons older than 7 years. A unique view into the progressive nature of the disorder was achieved by evaluation of seven affected persons from three consanguineous families, all carrying the homozygous p.Y226C mutation. CONCLUSIONS. Ophthalmic findings in persons with RDH12 mutations suggest that RDH12 loss-of-function results in a characteristic form of early and progressive rod-cone degeneration distinct from that caused by mutations in other LCA genes. From our data, it seems likely that various clinical designations appropriately describe the diagnosis in these persons, including early-onset retinitis pigmentosa, LCA type II, and childhood retinal dystrophy.

SAMPI: Protein Identification with Mass Spectra Alignments

Hans-Michael Kaltenbach, Andreas Wilke, Sebastian Böcker
2007 BMC Bioinformatics  
Mass spectrometry based peptide mass fingerprints (PMFs) offer a fast, efficient, and robust method for protein identification. A protein is digested (usually by trypsin) and its mass spectrum is compared to simulated spectra for protein sequences in a database. However, existing tools for analyzing PMFs often suffer from missing or heuristic analysis of the significance of search results and insufficient handling of missing and additional peaks. Results: We present an unified framework for
more » ... yzing Peptide Mass Fingerprints that offers a number of advantages over existing methods: First, comparison of mass spectra is based on a scoring function that can be custom-designed for certain applications and explicitly takes missing and additional peaks into account. The method is able to simulate almost every additive scoring scheme. Second, we present an efficient deterministic method for assessing the significance of a protein hit, independent of the underlying scoring function and sequence database. We prove the applicability of our approach using biological mass spectrometry data and compare our results to the standard software Mascot. Conclusion: The proposed framework for analyzing Peptide Mass Fingerprints shows performance comparable to Mascot on small peak lists. Introducing more noise peaks, we are able to keep identification rates at a similar level by using the flexibility introduced by scoring schemes.

Human dialogue modelling using machine learning [chapter]

Yorick Wilks, Nick Webb, Andrea Setzer, Mark Hepple, Roberta Catizone
2004 Current issues in linguistic theory  
We describe two major dialogue system segments: first we describe a Dialogue Manager which uses a representation of stereotypical dialogue patterns that we call Dialogue Action Frames and which, we believe, generate strong and novel constraints on later access to incomplete dialogue topics. Secondly, an analysis module that learns to assign dialogue acts from corpora, but on the basis of limited quantities of data, and up to what seems to be some kind of limit on this task, a fact we also discuss.

Fingerprinting Analog IoT Sensors for Secret-Free Authentication [article]

Felix Lorenz, Lauritz Thamsen, Andreas Wilke, Ilja Behnke, Jens Waldmüller-Littke, Ilya Komarov, Odej Kao, Manfred Paeschke
2020 arXiv   pre-print
Especially in context of critical urban infrastructures, trust in IoT data is of utmost importance. While most technology stacks provide means for authentication and encryption of device-to-cloud traffic, there are currently no mechanisms to rule out physical tampering with an IoT device's sensors. Addressing this gap, we introduce a new method for extracting a hardware fingerprint of an IoT sensor which can be used for secret-free authentication. By comparing the fingerprint against reference

Our approach exploits the characteristic behavior of analog circuits, which is revealed by applying a fixed-frequency alternating current to the sensor, while recording its output voltage. To demonstrate the general feasibility of our method, we apply it to four commercially available temperature sensors using laboratory equipment and evaluate the accuracy. The results indicate that with a sensible configuration of the two hyperparameters we can identify individual sensors with high probability, using only a few recordings from the target device.
