text: "We analyse an InAs/GaAs-based electric field tunable single quantum dot diode
with a thin tunnelling barrier between a\r\nburied n þ -back contact and a quantum
dot layer. In voltage- dependent photoluminescence measurements, we observe rich
signatures from spatially direct and indirect transitions from the wetting layer
and from a single quantum dot. By analysing the Stark effect, we show that the
indirect transitions result from a recombination between confined holes in the
wetting or quantum dot layer with electrons from the edge of the Fermi sea in
the back contact. Using a 17 nm tunnel barrier which provides comparably weak
tunnel coupling allowed us to observe clear signatures of direct and corresponding
indirect lines for a series of neutral and positively charged quantum dot states."

text: "We report about the fabrication and analysis of high Q photonic crystal cavities
with metallic\r\nSchottky-contacts. The structures are based on GaAs n-i membranes
with an InGaAs quantum well\r\nin the i-region and nanostructured low ohmic metal
top-gates. They are designed for photocurrent\r\nreadout within the cavity and
fast electric manipulations. The cavity structures are characterized by\r\nphotoluminescence
and photocurrent spectroscopy under resonant excitation. We find strong cavity\r\nresonances
in the photocurrent spectra and surprisingly high Q-factors up to 6500. Temperature
dependent\r\nphotocurrent measurements in the region between 4.5K and 310K show
an exponential\r\nenhancement of the photocurrent signal and an external quantum
efficiency up to 0.26."

text: An electric field applied to a semiconductor reduces its crystal symmetry
and modifies its electronic structure which is expected to result in changes of
the linear and nonlinear response to optical excitation. In GaAs, we observe experimentally
strong electric field effects on the optical second (SHG) and third (THG) harmonic
generation. The SHG signal for the laser-light k vector parallel to the [001]
crystal axis is symmetry forbidden in the electric-dipole approximation, but can
be induced by an applied electric field in the vicinity of the 1s exciton energy.
Surprisingly, the THG signal, which is allowed in this geometry, is considerably
reduced by the electric field. We develop a theory which provides good agreement
with the experimental data. In particular, it shows that the optical nonlinearities
for the 1s exciton resonance are modified in an electric field by the Stark effect,
which mixes the 1s and 2p exciton states of opposite parity. This mixing acts
in opposite way on the SHG and THG processes, as it leads to the appearance of
forbidden SHG in (001)-oriented GaAs and decreases the crystallographic THG.

text: We use a picosecond acoustics technique to modulate the laser output of electrically
pumped GaAs/AlAs micropillar lasers with InGaAs quantum dots. The modulation of
the emission wavelength takes place on the frequencies of the nanomechanical extensional
and breathing (radial) modes of the micropillars. The amplitude of the modulation
for various nanomechanical modes is different for every micropillar which is explained
by a various elastic contact between the micropillar walls and polymer environment.

text: Terahertz frequency band of 0.06 - 10 THz is especially interesting for ultra-high-speed
wireless communication to achieve data rates of 100 Gbps or higher. To accommodate
this demand, advanced terahertz signal processing techniques need to be investigated.
Parallel Sequence Spread Spectrum (PSSS) is a physical layer (PHY) baseband technology
that seems to be suited for being used for ultra-high speed wireless communication
since the receiver architecture is especially simple and can be implemented almost
completely in analog hardware. In this paper, a PSSS modulated signal at a chip
rate of 20 Gcps with a spectral efficiency of (only) 1 bit/s/Hz is transmitted
using a linearity limited 240 GHz wireless frontend. PSSS transceiver models are
realized offline in MATLAB/Simulink. The PSSS transmitter generates the PSSS modulated
symbols that are loaded onto an Arbitrary Waveform generator (AWG) and then transmitted
using the available 240 GHz wireless frontend. A Digital Storage Oscilloscope
(DSO) samples and stores the received signal. The PSSS receiver performs synchronization,
channel estimation and demodulation. For a coded data rate of 20 Gbps, an eye
opening of 40% and a BER of 5.4·10 -5 has been measured. These results are highly
promising to achieve data rates of up to 100 Gbps with PSSS modulation using a
RF-frontend having higher linear operating range and thus allowing increasing
the bandwidth efficiency to 4 b/s/Hz.

text: Parallel Sequence Spread Spectrum (PSSS) is a physical layer baseband technology
wherein parallel data streams are transmitted simultaneously by spreading them
using orthogonal codes. PSSS was selected for the wireless sensor network standard
IEEE802.15.4-2006 to increase data rate and improve performance in fading channels
for frequency bands below 1 GHz. Since then it has gained interest for both wireless
and wired communication links.

abstract:
- lang: eng
text: The need for automatic methods of topic discovery in the Internet grows exponentially
with the amount of available textual information. Nowadays it becomes impossible
to manually read even a small part of the information in order to reveal the underlying
topics. Social media provide us with a great pool of user generated content, where
topic discovery may be extremely useful for businesses, politicians, researchers,
and other stakeholders. However, conventional topic discovery methods, which are
widely used in large text corpora, face several challenges when they are applied
in social media and particularly in Twitter – the most popular microblogging platform.
To the best of our knowledge no comprehensive overview of these challenges and
of the methods dedicated to address these challenges does exist in IS literature
until now. Therefore, this paper provides an overview of these challenges, matching
methods and their expected usefulness for social media analytics.
