Chord Label Personalization through Deep Learning of Integrated Harmonic Interval-based Representations

The increasing accuracy of automatic chord estimation systems, the availability of vast amounts of heterogeneous reference annotations, and insights from annotator subjectivity research make chord label personalization increasingly important. Nevertheless, automatic chord estimation systems are historically exclusively trained and evaluated on a single reference annotation. We introduce a first approach to automatic chord label personalization by modeling subjectivity through deep learning of a harmonic interval-based chord label representation. After integrating these representations from multiple annotators, we can accurately personalize chord labels for individual annotators from a single model and the annotators' chord label vocabulary. Furthermore, we show that chord personalization using multiple reference annotations outperforms using a single reference annotation.Comment: Proceedings of the First International Conference on Deep Learning and Music, Anchorage, US, May, 2017 (arXiv:1706.08675v1 [cs.NE]

Novel thin film polymer foaming technique for low and ultra low-k dielectrics

The results presented show a novel route for the preparation of thin ultra-low-k polymer films based on commercial and "non-exotic" (non-expensive) polyimide by a foaming technique. Dependent on the glass transition temperature of the polyimide mechanically and thermally stable (> 300 °C) films having porosities of ca. 40 % and k-values below 2.0 are formed. A further reduction into the ultra low k region may be accomplished by tailoring the shape of the pores from spherical into disc-like void

Purification and analytical characterization of an anti- CD4 monoclonal antibody for human therapy

A purification process for the monclonal anti-CD4 antibody MAX.16H5 was developed on an analytical scale using (NH&SO, precipitation, anion-exchange chromatography on MonoQ or Q-Sepharose, hydrophobic interaction chromatography on phenyl- Sepharose and gel filtration chromatography on Superdex 200. The purification schedule was scaled up and gram amounts of MAX.16H5 were produced on corresponding BioPilot columns. Studies of the identity, purity and possible contamination by a broad range of methods showed that the product was highly purified and free from contaminants such as mouse DNA, viruses, pyrogens and irritants. Overall, the analytical data confirm that the monoclonal antibody MAX.16H5 prepared by this protocol is suitable for human therapy

Bridging the Accountability Gap: Rights for New Entities in the Information Society?

Technological developments in the information society bring new challenges, both to the applicability and to the enforceability of the law. One major challenge is posed by new entities such as pseudonyms, avatars, and software agents that operate at an increasing distance from the physical persons "behind" them (the "principal"). In case of accidents or misbehavior, current laws require that the physical or legal principal behind the entity be found so that she can be held to account. This may be problematic if the linkability of the principal and the operating entity is questionable. In light of the ongoing developments in electronic agents, there is sufficient reason to conduct a review of the literature in order to more closely examine arguments for and against legal personhood for some nonhuman acting entities. This article also includes a discussion of alternative approaches to solving the "accountability gap.

Origin of the shadow Fermi surface in Bi-based cuprates

We used angle-resolved photoemission spectroscopy to study the shadow Fermi surface in one layer Bi2Sr1.6La0.4CuO6+delta and two layer (Bi,Pb)2Sr2CaCu2O8+delta. We find the shadow band to have the same peakwidth and dispersion as the main band. In addition, the shadow band/main band intensity ratio is found to be binding energy independent. Consequently, it is concluded that the shadow bands in Bi-based HTSC do not originate from antiferromagnetic interactions but have a structural origin.Comment: 10 pages, 2 figure

Phonon relaxation of subgap levels in superconducting quantum point contacts

Superconducting quantum point contacts are known to possess two subgap states per each propagating mode. In this note we compute the low-temperature relaxation rate of the upper subgap state into the lower one with the emission of an acoustic phonon. If the reflection in the contact is small, the relaxation time may become much longer than the characteristic lifetime of a bulk quasiparticle.Comment: REVTeX, 4 page

Is radiographic progression of late-onset rheumatoid arthritis different from young-onset rheumatoid arthritis? Results from the Swiss prospective observational cohort

Objective. RA can be categorized into late-onset RA (LORA, >60-65 years) and young-onset RA (YORA, 30-55 years), depending on the patient's age at disease onset. Since the average age of the population is continuously increasing, LORA will most probably gain in importance in the future. Despite this growing importance, LORA has not been the focus of much interest in the past. The aim of this study was to analyse radiographic damage progression of early disease in LORA compared with YORA patients. Methods. We included all patients from the Swiss RA registry, Swiss Clinical Quality Management in RA, with recent-onset arthritis, either RA (disease duration ≤1 year) or undifferentiated arthritis, as diagnosed by the data-entering physician. Patients were followed for 5 years. The cut-off between YORA and LORA was operationally set at 60 years of age. The primary outcome of this study was disease progression and activity, which was assessed based on the 28-joint DAS (DAS28) and the progression of joint erosions using a validated scoring system (Ratingen score). Results. A total of 592 patients with early disease were analysed. The age at disease onset had a Gaussian distribution, with a single peak at 54 years of age; 366 patients were categorized as YORA and 226 as LORA at disease onset. DAS28 scores were significantly higher among LORA as compared with YORA patients (4.8 vs 4.5, P = 0.049). Corticosteroids were used in 68% of LORA patients as a first-line treatment, compared with 25.4% in YORA patients (χ2 test: 54.58; P < 0.0001). In contrast, DMARDs were used in 100% of the YORA patients as first-line treatment, compared with 91.2% of the LORA patients. During follow-up, new glucocorticoids, synthetic DMARDs or biologic DMARDs were initiated in 32.8%, 61.1% and 14.1% of all YORA patients and 17.5%, 54.6% and 6.6% of LORA patients, respectively (χ2 test: 7.08, 22.53, 54.4; all P < 0.01). The DAS28 scores decreased in both groups during the observed time period, and the initial differences in disease activity vanished after 6 months and during the subsequent follow-up. The Ratingen score was higher in LORA than in YORA patients at inclusion (12.7 vs 5.6, P < 0.0001). The rate of radiographic progression at 5 years was similar when comparing LORA and YORA (3.3 vs 2.6, respectively, P = 0.64). The Ratingen scores at onset and during follow-up over 5 years did not clearly separate LORA and YORA into two groups, but rather, increased linearly when comparing the patients in groups per decade from 20 to 92 years of age. Conclusion. Our results did not show LORA as a separate subgroup of RA with a different prognosis with regard to radiographic progressio
