text: Multimode squeezed light is an increasingly popular tool in photonic quantum
technologies, including sensing, imaging, and computation. Meanwhile, the existing
methods of its characterization are technically complicated, which reduces the
level of squeezing, and mostly deal with a single mode at a time. Here, for the
first time, to the best of our knowledge, we employ optical parametric amplification
to characterize multiple squeezing eigenmodes simultaneously. We retrieve the
shapes and squeezing degrees of all modes at once through direct detection followed
by modal decomposition. This method is tolerant to inefficient detection and does
not require a local oscillator. For a spectrally and spatially multimode squeezed
vacuum, we characterize eight strongest spatial modes, obtaining squeezing and
anti-squeezing values of up to −5.2 ± 0.2 dB and 8.6 ± 0.3 dB, respectively, despite
the 50% detection loss. This work, being the first exploration of an optical parametric
amplifier’s multimode capability for squeezing detection, paves the way for the
real-time detection of multimode squeezing.

text: 'The sliding square model is a widely used abstraction for studying self-reconfigurable
robotic systems, where modules are square-shaped robots that move by sliding or
rotating over one another. In this paper, we propose a novel distributed algorithm
that enables a group of modules to reconfigure into a rhombus shape, starting
from an arbitrary side-connected configuration. It is connectivity-preserving
and operates under minimal assumptions: one leader module, common chirality, constant
memory per module, and visibility and communication restricted to immediate neighbors.
Unlike prior work, which relaxes the original sliding square move-set, our approach
uses the unmodified move-set, addressing the additional challenge of handling
locked configurations. Our algorithm is sequential in nature and operates with
a worst-case time complexity of O(n^2) rounds, which is optimal for sequential
algorithms. To improve runtime, we introduce two parallel variants of the algorithm.
Both rely on a spanning tree data structure, allowing modules to make decisions
based on local connectivity. Our experimental results show a significant speedup
for the first variant, and a linear average runtime for the second variant, which
is worst-case optimal for parallel algorithms.'

text: "Abstract\r\n Industrial x-ray
computed tomography (CT) systems with high geometric flexibility are increasingly
utilized for large-scale measurement objects or challenging measurement tasks.
To maintain high accuracy when deviating from the established circular scan trajectory,
trajectory calibration methods using multi-sphere reference objects with known
marker positions are commonly employed. These multi-sphere objects can either
be scanned together with the measurement object (online trajectory calibration)
or in a separate scan (offline trajectory calibration). While offline calibration
increases machine time, it generally results in higher scan quality. However,
a sufficient pose repeatability is necessary to ensure comparable or even superior
accuracy to online calibration. In this contribution, we present a straightforward
procedure to compare both types of trajectory calibration in a way that the differences
of the results can directly be traced back to the influence of the pose repeatability.
The multi-sphere reference object is not only used for trajectory calibration,
but simultaneously as a measurement object for repeated measurements. The methodology
is tested on both a twin robotic CT system and a conventional CT system that is
additionally equipped with a hexapod manipulator for adaptive object tilting.
Results showed, independent from the type of trajectory calibration, systematic
measurement errors in the order of 10−5–10−4
of measured sphere distances and sphericity values below 50 \r\n
\ \r\n \r\n \r\n \r\n
\ μ\r\n \r\n
\ \r\n m\r\n \r\n
\ \r\n \r\n .
For sphere distances, random errors were increased by a factor of 5 due to the
offline trajectory calibration, but were still low (\r\n
\ \r\n \r\n \r\n \r\n
\ <\r\n \r\n
\ \r\n 1\r\n
\ \r\n \r\n \r\n μ\r\n
\ \r\n \r\n
\ m\r\n \r\n
\ \r\n \r\n )
in comparison to systematic errors and the spread of different measurement features.
Overall, both investigated systems demonstrated sufficient positioning repeatability
for offline trajectory calibration. The method is in general also applicable to
any other types of manipulator systems used for CT devices. It provides a workflow
for the decision which type of trajectory calibration is preferable for a given
CT system."

text: Selecting tasks is a typical job in everyday teaching that requires teachers
to have content-specific expertise, including categories to think about and perceive
conceptual understanding. This contribution investigates the activation of prospective
teachers’ categories when solving tasks on the scalar product and evaluating their
relevance for teaching in upper secondary school. To further investigate, whether
input on content-related aspects could be helpful to promote a professional justification
for the selection of tasks, two groups with and without input are to be differentiated.
Different ways of dealing with underlying concept elements and evaluating the
relevance of tasks are discussed by examples.
