text: ' Boomerangs, that is, rehires, should have advantages over other
new hires when integrating into an organization due to their familiarity with
the work context and their pre-existing relationships. However, research suggests
that the effects of hiring boomerangs may not be straightforwardly positive. To
better understand these effects, we investigate how boomerangs’ social integration
into a work team differs from that of other new hires due to their pre-existing
relationships and how those relationships shape their and incumbents’ competence
and motivation to provide assistance for collective performance. We theorize and
find that boomerangs, compared with new hires, exhibit more performance assistance
toward incumbent former and incumbent new colleagues. In contrast, incumbent former
colleagues do not direct their performance assistance toward boomerangs, contrary
to our prediction, nor do incumbent new colleagues. This study contributes to
the nascent literature on boomerangs and the literature on job mobility by finding
evidence that prior relationships condition the behavior of both boomerangs and
incumbents. Supplemental Material: The online appendix is available

text: Additive manufacturing of metallic components often results in the
formation of columnar grain structures aligned along the build direction. These
elongated grains can introduce anisotropy, negatively impacting the mechanical
properties of the components. This study aimed to achieve controlled solidification
with a fine-grained microstructure to enhance the mechanical performance of printed
parts. Stainless steel 316L was used as the test material. High-intensity ultrasound
was applied during the direct energy deposition (DED) process to inhibit the formation
of columnar grains. The investigation emphasized the importance of amplitude changes
of the ultrasound wave as the system’s geometry continuously evolves with the
addition of multiple layers and assessed how these changes influence the grain
size and distribution. Initial tests revealed significant amplitude fluctuations
during layer deposition, highlighting the impact of layer deposition on process
uniformity. The mechanical results demonstrated that the application of ultrasound
effectively refined the grain structure, leading to a 15% increase in tensile
strength compared to conventionally additively manufactured samples.

text: "We propose and analyze deterministic protocols to generate qudit
photonic graph states from quantum emitters. We show that our approach can be
applied to generate any qudit graph state and we exemplify it by constructing
protocols to generate one- and two-dimensional qudit cluster states, absolutely
maximally entangled states, and logical states of quantum error-correcting codes.
Some of these protocols make use of time-delayed feedback, while others do not.
The only additional resource requirement compared to the qubit case is the ability
to control multilevel emitters. These results significantly broaden the range
of multiphoton entangled states that can be produced deterministically from quantum
emitters.\r\n \r\n \r\n \r\n

text: 'AbstractMechanical clinching is a frequently
used joining method for technical components. These joints are usually weak spots.
Here, corrosion and fatigue are decisive influencing factors for the assessment
of the service life of such joints. Corrosion generally leads to material deterioration
and thus to premature failure of the joints. Under certain circumstances, however,
corrosion can lead to an increased fatigue life. While this effect has not yet
been fully understood, the present work provides a possible explanation and a
modeling approach to predict the fatigue life of precorroded clinched joints.
The increased fatigue life is observed when the clinched components are briefly
(up to 3 weeks) exposed to a salt spray environment. During this time, a small
layer of corrosion products protrudes from the metal surface and fills the gaps
between the joined sheets. Due to the increased contact area, the mechanical stress
in the joint decreases, resulting in an improved fatigue performance. Although
there are a variety of corrosion phenomena, for example, pitting, intergranular,
and transgranular corrosion as well as galvanic corrosion, experimental studies
indicate that galvanic corrosion is the main contributor of this effect. In the
present work, a coupled electro‐chemo‐mechanical corrosion model is presented
and applied to two test cases. Case I: corrosion products growth, and Case II:
corrosion products growth and mechanical loading.'

text: Controlling the intensity of emitted light and charge current is the basis
of transferring and processing information1. By contrast, robust information storage
and magnetic random-access memories are implemented using the spin of the carrier
and the associated magnetization in ferromagnets2. The missing link between the
respective disciplines of photonics, electronics and spintronics is to modulate
the circular polarization of the emitted light, rather than its intensity, by
electrically controlled magnetization. Here we demonstrate that this missing link
is established at room temperature and zero applied magnetic field in light-emitting
diodes2,3,4,5,6,7, through the transfer of angular momentum between photons, electrons
and ferromagnets. With spin–orbit torque8,9,10,11, a charge current generates
also a spin current to electrically switch the magnetization. This switching determines
the spin orientation of injected carriers into semiconductors, in which the transfer
of angular momentum from the electron spin to photon controls the circular polarization
of the emitted light2. The spin–photon conversion with the nonvolatile control
of magnetization opens paths to seamlessly integrate information transfer, processing
and storage. Our results provide substantial advances towards electrically controlled
ultrafast modulation of circular polarization and spin injection with magnetization
dynamics for the next-generation information and communication technology12, including
space–light data transfer. The same operating principle in scaled-down structures
or using two-dimensional materials will enable transformative opportunities for
quantum information processing with spin-controlled single-photon sources, as
well as for implementing spin-dependent time-resolved spectroscopies.

text: A numerical modelling strategy for the direct pin pressing process
of metallic pins into continuous fibre-reinforced thermoplastic organosheets is
developed. The joining process is performed above the thermoplast’s melting temperature,
altering the initial material structure of the composite by fibre rearrangement,
which in turn influences the load-bearing capacity of the joint. Therefore, the
modelling strategy aims at predicting the resultant material structure after pin
pressing. The modelling approach considers both the textile architecture and the
process parameters (temperature, tool velocity). A sub-meso modelling framework
for the fibres based on a multi-filament approach is used. The interaction between
fibres and the thermoplastic melt, as well as the matrix flow, is modelled using
the Arbitrary Lagrangian Eulerian method. This allows for the prediction of matrix-rich
zones and fibre rearrangement around the pin. The promising results show a good
agreement of the resultant material structure in terms of compaction and fibre
volume content around the pressed pin. Characteristic parameters show an underestimation
of the laminate thickness below the pin. Moreover, an evaluation method for evaluating
the orientation changes of the virtual multi-filaments is developed and presented
to observe and assess fibre rearrangement and fibre volume content in detail during
the numerical process simulation. It can be seen that only fibres around the pin
are displaced and not in the whole molten area. Furthermore, it can be observed
in detail that the initial position of the fibres in relation to the pin determines
whether the fibres are displaced in the in-plane or out-of-plane direction.
