In this article the test response is compacted by several multiple input shift registers without feedback (NF-MISR). The shift registers are running on a k-times higher clock frequency than the test clock. For each test clock cycle only one out of the k outputs of each shift register is evaluated by the ATE. The impact of consecutive X values within the scan chains is reduced by a periodic permutation of the NF-MISR inputs. As a result, no additional external control signals or test set dependent control logic is required. The benefits of the proposed method are shown by the example of an implementation on a Verigy ATE. Experiments on three industrial circuits demonstrate the effectiveness of the proposed approach in comparison to a commercial DFT solution.

The key component is a hierarchical configurable masking register, which allows the compactor to dynamically adapt to and provide excellent performance over a wide range of x-densities. A major contribution of this paper is a technique that enables the efficient loading of the x-masking data into the masking logic in a parallel fashion using the scan chains. A method for eliminating the requirement for dedicated mask control signals using automated test equipment timing flexibility is also presented. The proposed compactor is especially suited to multisite testing. Experiments with industrial designs show that the proposed compactor enables compaction ratios exceeding 200x.

This potentially provides the opportunity to construct precise chronologies by counting annual laminae. The growth period of the three stalagmites was constrained by the C-14 bomb peak in the youngest part of all three stalagmites and C-14-dating of a piece of charcoal in the consolidated base part of stalagmite Zoo-rez-2. These data suggest an age of AD 1970 for the top laminae and a lower age limit of AD 1973-1682 or AD 1735-1778. Laminae were counted and their thickness determined on scanned thin sections of all stalagmites. On stalagmites Zoo-rez-1 and -2, three tracks were measured near the growth axes, each separated into three sections at prominent anchor laminae (I, II, III). Each section was replicated three times (a, b, c). For Zoo-rez-3, only one track was measured. The total number of laminae counted for Zoo-rez-1 ranges from 138 to 177, for Zoo-rez-2 from 119 to 145, and for Zoo-rez-3 from 159 to 166. The numbers agree well with the range constrained by the bomb peak and the age of the charcoal, which supports the annual origin of the laminae. The replicated measurements of the different tracks as well as the three different tracks on the stalagmites Zoo-rez-1 and-2 were cross-dated using the TSAP-Win (R) tree-ring software. This software is very useful for cross-dating because it enables to insert or delete missing or false laminae as well as identifying common pattern by shifting the series back and forth in time. However, visual inspection of the thin sections was necessary to confirm detection of missing or false laminae by TSAP-Win (R). For all three Zoo-rez speleothems, crossdating of the mean lamina thickness series was not possible due to a missing common pattern. The cross-dating procedure results in three refined chronologies for the three Zoo-rez stalagmites of ranging from AD 1821-1970 (Zoo-rez-1), AD 1835-1970 (Zoo-rez-2), and AD 1808-1970 (Zoo-rez-3).

T1 - Validierung des Singing Voice Handicap Index in der deutschen Fassung JF - HNO N2 - Der Singing Voice Handicap Index (SVHI) wurde zur Selbstbeurteilung einer Stimmstörung für Sänger in den USA entwickelt. Eine deutsche Übersetzung wurde erstellt und einer Reliabilitäts- und Validitätsprüfung unterzogen. Es wurden 54 dysphone Sänger (35 weiblich, 19 männlich), Patienten einer phoniatrischen Klinik, befragt. 130 stimmgesunde Opern- und Rundfunkchorsänger (74 weiblich, 56 männlich) bildeten die Kontrollgruppe. Die Reliabilität ergibt sich aus einer hochsignifikanten Test-Retest-Reliabilität (r = 0,960; p <= 0,001, Pearson-Korrelation) und einem Cronbach-? von 0,975. Eine Hauptkomponentenanalyse mit Varimaxrotation und die Ergebnisse des Screeplots legen die Interpretation des SVHI als einfaktorielle Skala nahe. Die Validität zeigt sich in einem hochsignifikanten Zusammenhang zwischen dem vom Patienten selbst eingeschätzten Schweregrad der Stimmstörung und dem SVHI-Gesamtscore. Patienten haben einen signifikant höheren SVHI-Gesamtscore als die Kontrollgruppe gesunder Sänger. Der SVHI ist als diagnostisches Instrument für den deutschsprachigen Raum geeignet.

These results brought to light significant differences, due to age, in the interpretation and acceptance of these resultatives, that is to say, sentences with an adjective in the final position. The youngest participants were prone to accept ungrammatical sentences by assigning a resultative meaning. The ungrammaticality of the sentences in question was not due to semantic inconsistencies but to violations of the selectional properties of verbs, as for instance in *die Kinder erschrecken die Katze angstlich 'the children frighten the cat scared'. In contrast, the adults rejected or amended those sentences. The conclusion is (a) that the children seemed to rely on the sentence structure as a primary cue to compute the meaning of an utterance and (b) that, in contrast with adults, the youngest children in particular had not yet learned the relevant semantic properties of verbs that determine the selectional restrictions and thus the syntactic options of verbs. This means that differences in interpretation and acceptance of sentences are due to differences in knowledge of semantic verb properties between adults and children. The relevant semantic knowledge increases in gradual stages during language acquisition.

We map the interstellar medium (ISM) including the diffuse interstellar bands (DIBs) in absorption toward the globular cluster NGC6397 using VLT/MUSE. Assuming the absorbers are located at the rim of the Local Bubble we trace structures on the order of mpc (milliparsec, a few thousand AU). Aims. We aimed to demonstrate the feasibility to map variations of DIBs on small scales with MUSE. The sightlines defined by binned stellar spectra are separated by only a few arcseconds and we probe the absorption within a physically connected region. Methods. This analysis utilized the fitting residuals of individual stellar spectra of NGC6397 member stars and analyzed lines from neutral species and several DIBs in Voronoi-binned composite spectra with high signal-to-noise ratio (S/N). Results. This pilot study demonstrates the power of MUSE for mapping the local ISM on very small scales which provides a new window for ISM observations. We detect small scale variations in Na-I and K-I as well as in several DIBs within few arcseconds, or mpc with regard to the Local Bubble. We verify the suitability of the MUSE 3D spectrograph for such measurements and gain new insights by probing a single physical absorber with multiple sight lines.

In this study the influence of pH-buffers and their concentrations, the charge density (AAA content) in microgel particles as well as the spacer length of the surfactant on the complex formation between the microgel and surfactant is investigated. It is shown that the presence of pH buffer can lead to complete blocking of the interactions in such complexes and the resulting microgel contraction/swelling response. There is a clear competition between the buffer ions and the surfactant molecules interacting with microgel particles. When working in pure water solutions with fixed concentration (charge density) of microgel, the contraction/swelling of the particles is controlled only by relative concentration (charge ratio) of the surfactant and AAA groups of the microgel. Furthermore, the particle contraction is more efficient for shorter spacer length of the surfactant. The onset point of the contraction process is not affected by the surfactant hydrophobicity. This work provides new insight into the interaction between microgel particles and photo-sensitive surfactants, which offers high potential in new sensor systems. (C) 2014 Elsevier Ltd.
