ZusammenfassungZertifizierte Brustkrebszentren bieten spezifische Qualitätsstandards für die Struktur, Diagnostik und Behandlungsverfahren, beispielsweise der Mammachirurgie, medikamentösen
Tumortherapie, Strahlentherapie und psychosozialen Unterstützung, mit dem Ziel, die Behandlungsergebnisse für Brustkrebspatient*innen zu verbessern. Die Frage ist jedoch, ob Patient*innen mit
primärem Brustkrebs ein längeres Überleben haben, wenn sie in einem zertifizierten Brustkrebszentrum behandelt werden, im Vergleich zur Behandlung außerhalb dieser Zentren.Wir verwendeten patient*innenspezifische Informationen (demografische Merkmale, Diagnosen, Behandlungen) aus den Daten der gesetzlichen Krankenversicherung (GKV) und klinischer
Krebsregister (KKR) für den Zeitraum 2009–2017 sowie Krankenhausmerkmale aus den Standardisierten Qualitätsberichten. Wir untersuchten mittels multivariabler Cox-Regressionen Unterschiede im
Überleben zwischen Patient*innen, die in Kliniken mit und ohne Zertifizierung als Brustkrebszentrum der Deutschen Krebsgesellschaft (DKG) behandelt wurden.Die Stichprobe umfasste 143720 (GKV-Daten) bzw. 59780 (KKR-Daten) Patient*innen mit Brustkrebs, die in 1010 Krankenhäusern behandelt wurden (280 DKG-zertifiziert, 730 nicht
DKG-zertifiziert). 63,5% (GKV-Daten) bzw. 66,7% (KKR-Daten) der Patient*innen wurden in DKG-zertifizierten Brustkrebszentren behandelt. Cox-Regressionen für das Gesamtüberleben, bei denen
Patienten- und Krankenhausmerkmale berücksichtigt wurden, ergaben ein signifikant niedrigeres Sterberisiko für Patient*innen, die in DKG-zertifizierten Brustkrebszentren behandelt wurden
(GKV-Daten: HR = 0,77, 95%-KI = 0,74–0,81; KKR-Daten: HR = 0,88, 95%-KI = 0,85–0,92). Dieses Ergebnis blieb auch in mehreren Sensitivitätsanalysen stabil, einschließlich stratifizierter
Schätzungen für Untergruppen von Patient*innen und Krankenhäusern. Für das rezidivfreie Überleben war der Effekt noch stärker ausgeprägt (KKR-Daten: HR = 0,78, 95%-KI = 0,74–0,82).Patient*innen, die von einem interdisziplinären Team in einem DKG-zertifizierten Brustkrebszentrum behandelt wurden, wiesen ein deutlich und statistisch signifikant verbessertes Überleben
auf. Die Zertifizierung ist somit ein wirksames Mittel zur Verbesserung der Versorgungsqualität, und es sollten mehr Patient*innen in zertifizierten Brustkrebszentren behandelt werden.
Why Deep Plane Face and Neck Lifting Results in the Maximum Short- and Long-term Results? My Primary Choice for Rhytidectomy in My Practice
Authors: Batniji Rami K. 
Published: May 2024

AbstractI converted to the extended deep plane facelift and neck lift with a shorter skin flap elevation in the face to achieve a more complete release of the facial ligaments to obtain more mobilization of the skin/superficial musculoaponeurotic system composite flap, and a more medial suspension resulting in improved correction of the midface, nasolabial fold, marionette fold and jowl. Treatment of the deep neck structures allowed for more refinement of the submentum in the deep neck lift procedures as well. In this article, we shall review the surgical technique of the deep plane facelift and neck lift as well as postoperative management pearls, the management of complications from the procedure, and the incorporation of ancillary procedures.
Background Factors Associated with Postoperative Complications in Patients with Advanced Hypopharyngeal Cancers Undergoing Total Pharyngolaryngoesophagectomy Followed by Free Jejunal Flap Reconstruction

Published: May 2024

AbstractWe retrospectively analyzed background factors associated with postoperative complications in patients with advanced hypopharyngeal cancers who underwent total pharyngolaryngectomy followed by free jejunal flap reconstruction. A total of 23 participants, including 21 men and 2 women aged 49 to 83 years (average 72.3 years) were enrolled in this study. Mild and moderate/severe complications occurred in five and seven cases, respectively. The most common complication was stricture of the esophagojejunal anastomosis (nine cases). Other complications included two tracheostomal stenosis, one each for pneumonia and chyle leakage. The free jejunal flap survived in all cases. The disease-free survival rate was 47.8% at 52 weeks after surgery. The platelet count was significantly lower (18.8 ± 1.9 × 104/mL vs. 27.7 ± 1.8 × 104/mL; p = 0.008) in patients with moderate/severe complications than in those without. The percentage of stage IV cases and intraoperative blood loss tended to be higher in patients with complications than in those without. Knowledge of these potential risk factors for the development of postoperative complications to satisfactorily manage the clinical course of patients with advanced hypopharyngeal cancers is necessary.
Driving the EU working conditions directive: social partner reactivity and the limits to commission entrepreneurship
Authors: Mailand Mikkel 
Published: May 2024

AbstractThe EU’s social dimension has been strengthened since the mid-2010s. Recent research has shown how Commission entrepreneurship in meta-governance such as the European Pillar of Social Rights and the European Semester turned existing regulation in a more ‘social’ direction or led to new regulation strengthening Social Europe. This article asks whether the Commission also stands out as the most important actor in initiatives focused exclusively on working conditions and if the European social partners also in these are secondary reactive actors. Focusing on a recent case where the social partners had a treaty-based right to bargain—the Working Conditions Directive—the article confirms the Commission’s dominance and the reactivity of the social partners. The choice not to bargain reduces the social partners to lobbyists attempting to influence other key actors. However, the case also shows the limits to Commission entrepreneurship in that EU member states and the European Parliament were able to influence the outcome in important ways.
Layer-Valley Hall Effect under Inversion and Time-Reversal Symmetries

Abstract
Hall effects have been the central paradigms in modern physics, materials science and practical applications, and have led to many exciting breakthroughs, including the discovery of topological Chern invariants and the revolution of metrological resistance standard. To date, the Hall effects have mainly focused on a single degree of freedom (DoF), and most of them require the breaking of spatial-inversion and/or time-reversal symmetries. Here we demonstrate a new type of Hall effect, i.e., layer-valley Hall effect, based on a combined layer-valley DoF characterized by the product of layer and valley indices. The layer-valley Hall effect has a quantum origin arising from the layer-valley contrasting Berry curvature, and can occur in nonmagnetic centrosymmetric crystals with both spatial-inversion and time-reversal symmetries, transcending the symmetry constraints of single DoF Hall effect based on the constituent layer or valley index. Moreover, the layer-valley Hall effect is highly tunable and shows a W-shaped pattern in response to the out-of-plane electric fields. Additionally, we discuss the potential detection approaches and material-specific design principles of layer-valley Hall effect. Our results demonstrate novel Hall physics and open up exotic paradigms for new research direction of layer-valleytronics that exploits the quantum nature of the coupled layer-valley DoF.
Shooting stars on schedule: synchronising re-entry of particles launched from a satellite
Authors: Blanco Philip R 
Published: May 2024

Abstract
The ALE-3 mission plans to create artificial ‘shooting stars’ in the upper atmosphere by launching pellets sequentially from a satellite in low Earth orbit. How does one arrange for all pellets to re-enter over the intended location simultaneously? Starting with conservation of energy and angular momentum, I derive a version of Kepler’s equation that gives time as a function of radial distance in an orbit, which can be used to find the transfer time from the pellet’s ejection to its re-entry as a function of its launch velocity. I show that for a given pellet ejection speed, there is a launch angle from the satellite that results in the fastest transfer time. I use these results to determine the pellets’ launch times and velocities for simultaneous arrival at a desired re-entry point. These results can be applied to de-orbiting any set of objects launched from a satellite, and use concepts that can be covered in an advanced undergraduate course in physics or aerospace engineering.
Integrating Python data analysis in an existing introductory laboratory course
Authors: Tufino Eugenio , Oss Stefano , Alemani Micol 
Published: May 2024

Abstract
In this article we describe how we successfully incorporated data analysis in Python in a first year laboratory course without significantly altering the course structure and without overburdening students. We show how we created and used carefully designed Jupyter Notebooks with exercises and physics application examples that allow students to master data analysis programming in the laboratory course. We use these Notebooks to guide students through the fundamentals of data handling and analysis in Python while performing simple experiments. We present our teaching approach and the developed materials. We discuss the effectiveness of our intervention based on the results from pre- and post-course questionnaires and students’ group work. The results presented give insights about advantages and challenges of introducing computation at the early stage of the curriculum in a laboratory course setting and are informative for other instructors and the physics education research community.
The effects of active learning on students’ sense of belonging and academic performance in introductory physics courses
Authors: Li Yangqiuting , Bernardi Rafael C , Burkholder Eric 
Published: May 2024

Abstract
Research-based active learning strategies have been shown to have positive effects on students’ learning in physics class. However, the exploration of active learning’s impact on students’ sense of belonging in physics classrooms remains limited. In this paper, we present our findings pertaining to students’ sense of belonging in an introductory physics course at a large public research university. This course was taught by three different instructors, one of whom integrated research-based active learning strategies, while the other two employed traditional lecture-based approaches. Our results show a statistically significant decrease in the sense of belonging among students in the traditionally taught classes, in contrast to a modest increase in students’ sense of belonging in the active learning class. Furthermore, we observed a statistically significant gender difference in students’ sense of belonging at the beginning of the course, which was closed by the end of the active learning class but persisted in the traditional classes. In addition, the active learning class exhibited a positive impact on students’ academic outcomes, and this effect was partially mediated by the sense of belonging. Our findings indicate that active learning classes, particularly those thoughtfully designed to foster inclusive environments, may benefit students’ sense of belonging and enhance their academic performance without relying on the use of specific belonging interventions.
Variance sum rule: proofs and solvable models
Authors: Di Terlizzi Ivan , Baiesi Marco , Ritort Felix 
Published: May 2024

Abstract
We derive, in more general conditions, a recently introduced variance sum rule (VSR) (Di Terlizzi et al 2024 Science
383 971) involving variances of displacement and force impulse for overdamped Langevin systems in a nonequilibrium steady state (NESS). This formula allows visualising the effect of nonequilibrium as a deviation of the sum of variances from normal diffusion 2Dt, with D the diffusion constant and t the time. From the VSR, we also derive formulas for the entropy production rate σ that, differently from previous results, involve second-order time derivatives of position correlation functions. This novel feature gives a criterion for discriminating strong nonequilibrium regimes without measuring forces. We then apply and discuss our results to three analytically solved models: a stochastic switching trap, a Brownian vortex, and a Brownian gyrator. Finally, we compare the advantages and limitations of known and novel formulas for σ in an overdamped NESS.
Higher-order anti-PT-symmetric self-injection locking micro-resonator optical gyroscope
Authors: Geng Jingtong , Li Yuwei 
Published: May 2024

Abstract
The higher-order anti-parity-time(APT)-symmetric self-injection locking micro-resonator optical gyroscope sensing mechanism is proposed. In the third-order APT-symmetric exceptional points(EP) gyroscope system, the frequency splitting induced by rotation is directly proportional to the cube root of the rotation rate. Furthermore, this solution exhibits real frequency splitting, the half-width at half-maximum(FHWM) and spectral power of the resonance curve remain unchanged. Compared with the second-order PT-symmetric optical gyroscope, the proposed rotation sensing mechanism reduces the detection complexity and enhances the beat frequency detection accuracy, resulting in a sensitivity increase of at least one order of magnitude when the speed to be measured is less than 105 °/h. Moreover, the structure incorporates the self-injection locking signal processing method, thereby streamlining the system architecture and reducing both the cost and volume of the gyroscope. This sensing mechanism further improves the on-chip ultra-sensitive rotation sensing scheme and will contribute to the design of quantum gyroscopes.
Numerical investigation of high-order harmonic generation by gold nanorod arrays in hybrid nanostructures: effect of number of gold nanorod
Authors: Peymani Fatemeh , Bahari Ali 
Published: May 2024

Abstract
Hybrid metal-dielectric nanostructures are highly effective and helpful in generating and enhancing linear and nonlinear optical phenomena due to their unique optical properties. In this study, the linear optical responses and second- and third-order harmonics have been calculated numerically for this structure. Nonlinear optical response efficiency has been studied at the resonance wavelengths of the nanostructure by varying its parameters (radius and length). The desired efficiency can be achieved by adjusting the radius and length of the nanorods and matching the resonance wavelengths with the fundamental and generation frequencies of nonlinear optical phenomena in specific applications. Moreover, the effect of the number of gold nanorods on harmonic generation has been investigated. By increasing the number of nanorods in pairs, it is possible to generate high-order harmonics. The acquired results can be used to improve optical devices such as biomedical equipment, optical integrated circuits, and sensors.

Abstract
The transition between the spherical and deformed shapes of the nuclei (shape phase transition) is an interesting property of nuclei that enriches our understanding of the nuclear structure. One method for studying it is through measurement of a wide range of atomic masses and derivation of the two-neutron separation energies (S2n). Using a multiple-reflection time-of-flight mass spectrometer at the FRS Ion Catcher, GSI, atomic masses in the region of A ∼ 150 were measured. This allowed an wide study of phase shape transitions in this region of the nuclear chart. In addition, comparison with the Skyrme Hartree–Fock plus BCS approach are done; showing a remarkable good agreement between theory and experiment.

Published: May 2024

Abstract
For real-time processing of ultra-wide bandwidth low-frequency pulsar baseband data, we designed and implemented an ultra-wide bandwidth low-frequency pulsar data processing pipeline (UWLPIPE) based on the shared ringbuffer and GPU parallel technology. UWLPIPE runs on the GPU cluster and can simultaneously receive multiple 128 MHz dual-polarization VDIF data packets preprocessed by the front-end FPGA. After aligning the dual-polarization data, multiple 128M subband data are packaged into PSRDADA baseband data or multi-channel coherent dispersion filterbank data, and multiple subband filterbank data can be spliced into wideband data after time alignment. We used the Nanshan 26 m radio telescope with the L-band receiver at 964 ∼ 1732 MHz to observe multiple pulsars. Finally, we processed the data using DSPSR software, and the results showed that each subband could correctly fold out the pulse profile, and the wideband pulse profile accumulated by multiple subbands could be correctly aligned.

Published: May 2024

Abstract
The flexible perovskite light-emitting diodes (FPeLEDs), which can be expediently integrated to portable and wearable devices, have shown great potential in various applications. The FPeLEDs inherit the unique optical properties of metal halide perovskites, such as tunable bandgap, narrow emission linewidth, high photoluminescence quantum yield, and particularly, the soft nature of lattice. At present, substantial efforts have been made for FPeLEDs with encouraging external quantum efficiency (EQE) of 24.5%. Herein, we summarize the recent progress in FPeLEDs, focusing on the strategy developed for perovskite emission layers and flexible electrodes to facilitate the optoelectrical and mechanical performance. In addition, we present relevant applications of FPeLEDs in displays and beyond. Finally, perspective toward the future development and applications of flexible PeLEDs are also discussed.

Abstract
This paper presents the application of full time-dependent SOLPS-ITER simulations for actuator design in the SPARC tokamak. This study employs both the EIRENE module, a neutral solver, and the B2.5 plasma module in a time-dependent mode. This is in contrast to most SOLPS simulations, which focus on steady-state solutions, where the neutral distribution is evolved without any time limit or for a time step of 1

second, which is several orders of magnitude larger than the fluid plasma time step. The time-dependent EIRENE was tested with a fixed B2.5 background and compared with a simple conductance based model in a simplified pump chamber geometry. This comparison aimed to verify the reliability of the neutral relaxation timescale derived from the time-dependent EIRENE. Subsequently, a full time-dependent simulation was performed in a realistic geometry, with the Monte-Carlo neutral time step synchronized with the plasma fluid time step. The numerical setup of the code, including relative time steps and the size of the census data used to store Monte-Carlo particle information is considered. The full-time dependent simulations are then applied to inform the design of the SPARC louver structure, which affects divertor plasma parameters by regulating the neutral conductance from the divertor to the pump. The response of the plasma and neutral parameters was captured on a timescale that enables the design of the actuator to consider time-dependent control capability. It was found that changing the louver opacity has an equivalent effect as varying the gas throughput via puff actuation. Therefore, equivalent divertor plasma conditions can be obtained from both actuators, while the neutral pressure distribution in the pump and divertor differs for each actuator.
Many-body localization on finite generation fractal lattices
Authors: Manna Sourav , Jaworowski Błażej , Nielsen Anne E B 
Published: May 2024

Abstract
We study many-body localization in a hardcore boson model in the presence of random disorder on finite generation fractal lattices with different Hausdorff dimensions and different local lattice structures. In particular, we consider the Vicsek, T-shaped, Sierpinski gasket, and modified Koch-curve fractal lattices. In the single-particle case, these systems display Anderson localization for arbitrary disorder strength if they are large enough. In the many-body case, the systems available to exact diagonalization exhibit a transition between a delocalized and localized regime, visible in the spectral and entanglement properties of these systems. The position of this transition depends on the Hausdorff dimension of the given fractal, as well as on its local structure.
Design of active vibration isolation system for satellite optical load based on Stewart platform
Authors: Yang Songlin , Yang Haibo , Zhang Xiang , Xu Chang 
Published: May 2024

Abstract
According to the requirements of hyperstatic environment of a satellite optical load during in orbit operation, the Stewart active vibration isolation platform was designed, and its dynamic equation was established by Newton Euler method. The virtual prototype model was established in ADAMS, and the accuracy of the model was verified by comparing the numerical solution and simulation solution of the modal frequency of the platform; On this basis, the dynamic model is decoupled into six SISO systems, and the optimal controller is designed for each subsystem. Finally, the whole system is simulated by ADAMS/MATLAB, and the displacement response curves of the load before and after control are obtained. The simulation results show that the Stewart active vibration isolation platform can effectively suppress the vibration.
