text: We investigate the band dispersion and relevant electronic properties of rubrene
single crystals within the GW approximation. Due to the self-energy correction,
the dispersion of the highest occupied molecular orbital (HOMO) band increases
by 0.10 eV compared to the dispersion of the Kohn-Sham eigenvalues within the
generalized gradient approximation, and the effective hole mass consequently decreases.
The resulting value of 0.90 times the electron rest mass along the Γ-Y direction
in the Brillouin zone is closer to experimental measurements than that obtained
from density-functional theory. The enhanced bandwidth is explained in terms of
the intermolecular hybridization of the HOMO(Y) wave function along the stacking
direction of the molecules. Overall, our results support the bandlike interpretation
of charge-carrier transport in rubrene.

text: "Whispering gallery modes (WGMs) were observed in 60 nm thin cubic AlN microdisk
resonators containing a single layer of non-polar cubic GaN quantum dots. Freestanding
microdisks were patterned by means of electron beam lithography and a two step
reactive ion etching process. Micro-photoluminescence spectroscopy investigations
were performed for optical characterization. We analyzed the mode spacing for
disk diameters ranging from 2-4 lm. Numerical investigations using three dimensional
finite difference time domain calculations were in good agreement\r\nwith the
experimental data. Whispering gallery modes of the radial orders 1 and 2 were
identified by means of simulated mode field distributions."

text: 'We present a new technique to realize attribute-based encryption (ABE) schemes
secure in the standard model against chosen-ciphertext attacks (CCA-secure). Our
approach is to extend certain concrete chosen-plaintext secure (CPA-secure) ABE
schemes to achieve more efficient constructions than the known generic constructions
of CCA-secure ABE schemes. We restrict ourselves to the construction of attribute-based
key encapsulation mechanisms (KEMs) and present two concrete CCA-secure schemes:
a key-policy attribute-based KEM that is based on Goyal''s key-policy ABE and
a ciphertext-policy attribute-based KEM that is based on Waters'' ciphertext-policy
ABE. To achieve our goals, we use an appropriate hash function and need to extend
the public parameters and the ciphertexts of the underlying CPA-secure encryption
schemes only by a single group element. Moreover, we use the same hardness assumptions
as the underlying CPA-secure encryption schemes.'

text: In this contribution we derive the Maximum A-Posteriori (MAP) estimates of
the parameters of a Gaussian Mixture Model (GMM) in the presence of noisy observations.
We assume the distortion to be white Gaussian noise of known mean and variance.
An approximate conjugate prior of the GMM parameters is derived allowing for a
computationally efficient implementation in a sequential estimation framework.
Simulations on artificially generated data demonstrate the superiority of the
proposed method compared to the Maximum Likelihood technique and to the ordinary
MAP approach, whose estimates are corrected by the known statistics of the distortion
in a straightforward manner.

text: In this paper we present an improved version of the recently proposed Maximum
A-Posteriori (MAP) based noise power spectral density estimator. An empirical
bias compensation and bandwidth adjustment reduce bias and variance of the noise
variance estimates. The main advantage of the MAP-based postprocessor is its low
estimation variance. The estimator is employed in the second stage of a two-stage
single-channel speech enhancement system, where eight different state-of-the-art
noise tracking algorithms were tested in the first stage. While the postprocessor
hardly affects the results in stationary noise scenarios, it becomes the more
effective the more nonstationary the noise is. The proposed postprocessor was
able to improve all systems in babble noise w.r.t. the perceptual evaluation of
speech quality performance.

text: Among the different configurations of multi-microphone systems, e.g., in applications
of speech dereverberation or denoising, we consider the case without a priori
information of the microphone-array geometry. This naturally invokes explicit
or implicit identification of source-receiver transfer functions as an indirect
description of the microphone-array configuration. However, this blind channel
identification (BCI) has been difficult due to the lack of unique identifiability
in the presence of observation noise or near-common channel zeros. In this paper,
we study the implicit BCI performance of blind signal enhancement techniques such
as the adaptive principal component analysis (PCA) or the iterative blind equalization
and channel identification (BENCH). To this end, we make use of a recently proposed
metric, the normalized filter-projection misalignment (NFPM), which is tailored
for BCI evaluation in ill-conditioned (e.g., noisy) scenarios. The resulting understanding
of implicit BCI performance can help to judge the behavior of multi-microphone
speech enhancement systems and the suitability of implicit BCI to serve channel-based
(i.e., channel-informed) enhancement.

text: In this paper, we consider the Maximum Likelihood (ML) estimation of the parameters
of a GAUSSIAN in the presence of censored, i.e., clipped data. We show that the
resulting Expectation Maximization (EM) algorithm delivers virtually biasfree
and efficient estimates, and we discuss its convergence properties. We also discuss
optimal classification in the presence of censored data. Censored data are frequently
encountered in wireless LAN positioning systems based on the fingerprinting method
employing signal strength measurements, due to the limited sensitivity of the
portable devices. Experiments both on simulated and real-world data demonstrate
the effectiveness of the proposed algorithms.

text: Recently, substantial progress has been made in the field of reverberant speech
signal processing, including both single- and multichannel de-reverberation techniques,
and automatic speech recognition (ASR) techniques robust to reverberation. To
evaluate state-of-the-art algorithms and obtain new insights regarding potential
future research directions, we propose a common evaluation framework including
datasets, tasks, and evaluation metrics for both speech enhancement and ASR techniques.
The proposed framework will be used as a common basis for the REVERB (REverberant
Voice Enhancement and Recognition Benchmark) challenge. This paper describes the
rationale behind the challenge, and provides a detailed description of the evaluation
framework and benchmark results.

text: 'We present a novel method to exploit correlations of adjacent time-frequency
(TF)-slots for a sparseness-based blind speech separation (BSS) system. Usually,
these correlations are exploited by some heuristic smoothing techniques in the
post-processing of the estimated soft TF masks. We propose a different approach:
Based on our previous work with one-dimensional (1D)-hidden Markov models (HMMs)
along the time axis we extend the modeling to two-dimensional (2D)-HMMs to exploit
both temporal and spectral correlations in the speech signal. Based on the principles
of turbo decoding we solved the complex inference of 2D-HMMs by a modified forward-backward
algorithm which operates alternatingly along the time and the frequency axis.
Extrinsic information is exchanged between these steps such that increasingly
better soft time-frequency masks are obtained, leading to improved speech separation
performance in highly reverberant recording conditions.'

text: In this paper we consider the unsupervised word discovery from phonetic input.
We employ a word segmentation algorithm which simultaneously develops a lexicon,
i.e., the transcription of a word in terms of a phone sequence, learns a n-gram
language model describing word and word sequence probabilities, and carries out
the segmentation itself. The underlying statistical model is that of a Pitman-Yor
process, a concept known from Bayesian non-parametrics, which allows for an a
priori unknown and unlimited number of different words. Using a hierarchy of Pitman-Yor
processes, language models of different order can be employed and nesting it with
another hierarchy of Pitman-Yor processes on the phone level allows for backing
off unknown word unigrams by phone m-grams. We present results on a large-vocabulary
task, assuming an error-free phone sequence is given. We finish by discussing
options how to cope with noisy phone sequences.
