text: Optically nonlinear Pb2B5O9X (X = Cl, Br) borate halides are an important
group of materials for second harmonic generation (SHG). Additionally, they also
possess excellent photocatalytic activity and stability in the process of dechlorination
of chlorophenols, which are typical persistent organic pollutants. It would be
of great interest to conduct in situ (photo‐) catalysis investigations during
the whole photocatalytic process by SHG when considering them as photocatalytic
materials. In order to get superior photocatalytic efficiency and maximum surface
information, small particles are highly desired. Here, a low‐cost and fast synthesis
route that allows growing microcrystalline optically nonlinear Pb2B5O9X
borate halides at large quantities is introduced. When applying the ionothermal
growth process at temperatures between 130 and 170 °C, microcrystallites with
an average size of about 1 µm precipitate with an orthorhombic hilgardite‐like
borate halide structure. Thorough examinations using powder X‐ray diffraction
and scanning electron microscopy, the Pb2B5O9X microcrystals are indicated to
be chemically pure and single‐phased. Besides, the Pb2B5O9X borate halides' SHG
efficiencies are confirmed using confocal SHG microscopy. The low‐temperature
synthesis route thus makes these borate halides a highly desirable material for
surface studies such as monitoring chemical reactions with picosecond time resolution
and in situ (photo‐) catalysis investigations.

text: High-fidelity periodic poling over long lengths is required for robust, quasi-phase-matched
second-harmonic generation using the fundamental, quasi-TE polarized waveguide
modes in a thin-film lithium niobate (TFLN) waveguide. Here, a shallow-etched
ridge waveguide is fabricated in x-cut magnesium oxide doped TFLN and is poled
accurately over 5 mm. The high fidelity of the poling is demonstrated over long
lengths using a non-destructive technique of confocal scanning second-harmonic
microscopy. We report a second-harmonic conversion efficiency of up to 939 %/W
(length-normalized conversion efficiency 3757 %/Wcm²), measured at telecommunications
wavelengths. The device demonstrates a narrow spectral linewidth (1 nm) and can
be tuned precisely with a tuning characteristic of 0.1 nm/°C, over at least 40
°C without measurable loss of efficiency.

text: Quasi-phase-matched grating structures in lithium niobate waveguides with
sub-micrometer periodicities will benefit the development of short-wavelength
nonlinear optical devices. Here, we report on the reproducible formation of periodically
poled domains in x-cut single-crystalline thin-film lithium niobate with periodicities
as short as 600 nm. Shaped single-voltage poling pulses were applied to electrode
structures that were fabricated by a combination of electron-beam and direct-writing
laser lithography. Evidence of successful poling with good quality was obtained
through second-harmonic microscopy and piezoresponse force microscopy imaging.
For the sub-micrometer period structures, we observed patterns with a double periodicity
formed by domain interactions and features with sizes <200 nm.

text: "The aim of this study was to find out whether teaching how to search for
literature\r\nwould be more beneficial to students and teachers if done online
through short videos\r\nrather than in person during course time. To find out
whether online videos are more\r\nbeneficial, two courses were asked to fill in
questionnaires, one at the beginning and\r\none at the end of the semester. One
of the courses received the input online via videos\r\nand were given an exercise
to put the newly learned skills to use, the other course\r\nserved as a control
group and learned how to search for literature during the course.\r\nThe results
show that while the difference between the two groups is not significant,\r\nthe
videos can still be regarded as being more beneficial than teaching the necessary\r\nskills
during course time."

text: The detection of orchestrated and potentially manipulative campaigns in social
media is far more meaningful than an- alyzing single account behaviour but also
more challenging in terms of pattern recognition, data processing, and com- putational
complexity. While supervised learning methods need an enormous amount of reliable
ground truth data to find rather inflexible patterns, classical unsupervised learn-
ing techniques need a lot of computational power to handle large amount of data.
This makes them infeasible for real- time analysis. In this work, we demonstrate
the applicability of text stream clustering for the real-time detection of coordi-
nated campaigns.

text: In der Forschungsarbeit wird die Zeitungskommunikation des 18. Jahrhunderts
aus sprachwissenschaftlicher Perspektive untersucht. Es wird gezeigt, wie sich
das Textsortenrepertoire der Zeitung weiterentwickelte, welche sprachlichen Wandelprozesse
stattfanden und wie die Zeitung übergreifend allmählich zu einem Massenmedium
avancierte. Der textlinguistische Zugang auf die Zeitungssprache wird an den relevanten
Stellen ergänzt durch einschlägige Erkenntnisse aus der historischen Presseforschung
und der linguistischen Kulturanalyse. So wird etwa nachgezeichnet, wie sich die
Zeitungsschreiber im Laufe des Jahrhunderts immer stärker von den Einflüssen der
Kanzleisprachen lösten und Formulierungsstrategien etablierten, die auf die Anforderungen
des journalistischen Berichtens abgestimmt waren. Mit diesen und weiteren Ergebnissen
wird der Versuch angestellt, eine Forschungslücke der Sprachgeschichtsforschung
zu schließen, in der die Zeitungen des 18. Jahrhunderts bisher lediglich randständig
untersucht wurden.
