description: The D'yakonov-Perel' spin relaxation induced by the spin-orbit interaction is examined in disordered two-dimensional electron gas. It is shown that, because of the electron-electron interactions different spin relaxation rates can be obtained depending on the techniques used to extract them. It is demonstrated that the relaxation rate of a spin population is proportional to the spin-diffusion constant D_s, while the spin-orbit scattering rate controlling the weak-localization corrections is proportional to the diffusion constant D, i.e., the conductivity. The two diffusion constants get strongly renormalized by the electron-electron interactions, but in different ways. As a result, the corresponding relaxation rates are different, with the difference between the two being especially strong near a magnetic instability or near the metal-insulator transition.

description: We study large networks of parametric oscillators as heuristic solvers of random Ising models. In these networks, known as coherent Ising machines, the model to be solved is encoded in the coupling between the oscillators, and a solution is offered by the steady state of the network. This approach relies on the assumption that mode competition steers the network to the ground-state solution of the Ising model. By considering a broad family of frustrated Ising models, we show that the most-efficient mode does not correspond generically to the ground state of the Ising model. We infer that networks of parametric oscillators close to threshold are intrinsically not Ising solvers. Nevertheless, the network can find the correct solution if the oscillators are driven sufficiently above threshold, in a regime where nonlinearities play a predominant role. We find that for all probed instances of the model, the network converges to the ground state of the Ising model with a finite probability.

description: We show that a simple model of a spatially resolved evolving economic system, which has a steady state under simultaneous updating, shows stable oscillations in price when updated asynchronously. The oscillations arise from a gradual decline of the mean price due to competition among sellers competing for the same resource. This lowers profitability and hence population but is followed by a sharp rise as speculative sellers invade the large un-inhabited areas. This cycle then begins again.

description: We present a data analysis methodology for a model-independent reconstruction of the spectral shape of a stochastic gravitational wave background with LISA. We improve a previously proposed reconstruction algorithm that relied on a single Time-Delay-Interferometry (TDI) channel by including a complete set of TDI channels. As in the earlier work, we assume an idealized equilateral configuration. We test the improved algorithm with a number of case studies, including reconstruction in the presence of two different astrophysical foreground signals. We find that including additional channels helps in different ways: it reduces the uncertainties on the reconstruction; it makes the global likelihood maximization less prone to falling into local extrema; and it efficiently breaks degeneracies between the signal and the instrumental noise.

description: The Italian co-operative enterprises have prospered in the last thirty years in various sectors. In this essay we analyze the role played by managerilization in allowing Italian co-ops to compete nationally and internationally with capitalist enterprises. On the basis of a substantial set of company histories and managers interviews, we have built a three generations model of co-ops managers, which shows the changes that have allowed co-ops to become fully equipped with managerial skills. The strong leadership of umbrella organizations, the inner careers of most managers and legislation have been instrumental in avoiding demutualization, the killer of co-ops in many other countries.

description: The formation of massive objects via gravitational collapse is relevant both for explaining the origin of the first supermassive black holes and in the context of massive star formation. Here, we analyze simulations of the formation of massive objects pursued by different groups and in various environments, concerning the formation of supermassive black holes, primordial stars, as well as present-day massive stars. We focus particularly on the regime of small virial parameters, i.e., low ratios of the initial kinetic to gravitational energy, low to moderate Mach numbers, and the phase before feedback is very efficient. We compare the outcomes of collapse under different conditions using dimensionless parameters, particularly the star formation efficiency ε_*, the fraction f_* of mass in the most massive object relative to the total stellar mass, and the fraction f_{\rm tot} of mass of the most massive object as a function of the total mass. We find that in all simulations analyzed here, f_{\rm tot} increases as a function of ε_*, although the steepness of the increase depends on the environment. The relation between f_* and ε_* is found to be more complex and also strongly depends on the number of protostars present at the beginning of the simulations. We show that a collision parameter, estimated as the ratio of the system size divided by the typical collision length, allows us to approximately characterize whether collisions will be important. We analyze the statistical correlation between the dimensionless quantities using the Spearman coefficient and confirm via a machine learning analysis that good predictions of f_* can be obtained from ε_* together with a rough estimate of the collision parameter. This suggests that a good estimate of the mass of the most massive object can be obtained once the maximum efficiency for a given environment is known.

description: The C-metric is a solution to Einstein's vacuum field equation that describes an accelerating black hole. In this paper we discuss the propagation of light rays and the resulting lensing features in this metric. We first solve the lightlike geodesic equation using elliptic integrals and Jacobi elliptic functions. Then we fix a static observer in the region of outer communication of the C-metric and introduce an orthonormal tetrad to parameterise the directions of the light rays ending at the position of the observer using latitude-longitude coordinates on the observer's celestial sphere. In this parameterisation we rederive the angular radius of the shadow, we formulate a lens equation, and we derive the redshift and the travel time of light rays. We discuss the relevance of our theoretical results for detecting accelerating black holes described by the C-metric and for distinguishing them from non-accelerating black holes.

Locally advanced laryngeal cancer

description: Background and purpose: Bioselection with induction chemotherapy in larynx cancer is associated with excellent larynx preservation and disease-specific survival but requires visual inspection of the primary tumor. We retrospectively compare clinical and imaging response in bioselected patients to develop predictive models of surgeon-assessed response (SR), laryngectomy-free survival (LFS), and overall survival (OS) in bioselected patients. Materials and methods: In a secondary analysis of patients on two single-institution bioselection trials, model building used a regularized regression model (elastic-net) and applied nested cross-validation. Logistic regression-based model was used to predict SR and Cox proportional hazard-based models were used to predict LFS and OS. Results: In 115 patients with a median age of 57 years, most patients had supraglottic tumors (73.0%) and T3/T4 disease (94.8%). Definitive treatment was chemoradiation in 76.5% and laryngectomy in 23.5%. Change in primary tumor (OR = 5.78, p < 0.001) and N-classification (OR = 1.64, p = 0.003) predicted SR (AUC 0.847). Change in tumor volume (HR = 0.58, p < 0.001) predicted LFS (c-index 0.724). N-classification (HR = 1.48, p = 0.04) and pre-chemotherapy tumor volume (HR = 1.30, p = 0.174) predicted OS (c-index 0.552). Conclusions: Imaging offers a non-invasive opportunity to evaluate response to induction chemotherapy, complementary to surgeon assessment. Further evaluation of approaches to bioselection that optimize generalizability of this paradigm are needed, and clinical trials utilizing imaging to predict outcomes including LFS are warranted.

description: In this study, galaxy samples have been generated using mock observation techniques based on the results of TNG100-1 simulations to investigate three forms of intrinsic alignment: satellite-central alignment between the orientation of the brightest group galaxies (BGG) and the spatial distribution of their satellites, radial alignment between the satellites' orientation and the direction toward their BGG, as well as direct alignment between the orientation of BGG and that of its satellites. Overall, the predictions of galaxy alignment generally align with observations, although minor discrepancies have been identified. For satellite-central alignment, the alignment strength and color-dependence trends are well replicated by the mock observations. Regarding radial alignment, the signals are weak but discernible, with no apparent color dependence. As for direct alignment, no signal is detected, nor is there any color dependence. We also investigate the alignment dependencies on halo or the BGG properties, and proximity effect. For satellite-central alignment, the predicted alignment signal shows a positive correlation with halo and BGG mass, consistent with observations and previous predictions. Similar correlations have also been observed with the BGG age and metallicity, which merit future observational analysis for confirmation. Proximity effects have been observed for all three types of alignment, with satellites closer to the BGG exhibiting stronger alignment signals. The influence of galaxy definition and shape determination on alignment studies is also analyzed. This study underscores the importance of employing mock observation techniques for a fair comparison between predictions and observations.

description: Memory effects are a key feature in the description of the dynamical systems governed by the generalized Langevin equation, which presents an exact reformulation of the equation of motion. A simple measure for the estimation of memory effects is introduced within the framework of this description. Numerical calculations of the suggested measure and the analysis of memory effects are also applied for various model physical systems as well as for the phenomena of ``long time tails'' and anomalous diffusion.

description: We study the contribution of health-related behaviors to the health education gradient by distinguishing between short-run and long-run mediating effects: while in the former only behaviors in the immediate past are taken into account, in the latter we consider the entire history of behaviors. We use an empirical approach that addresses the endogeneity of education and behaviors in the health production function. Focusing on self-reported poor health, we find that education has a protective effect for European males and females aged 50. We also find that the mediating effects of health behaviors - measured by smoking, drinking, exercising and the body mass index - account in the short-run for 17% to 31% and in the long-run for 23% to 45% of the entire effect of education on health, depending on gender.

description: The doublet-triplet splitting problem can be simply solved in product-group GUT models, using a global symmetry that distinguishes the doublets from the triplets. Apart from giving the required mass hierarchy, this ``triplet symmetry'' can also forbid some of the triplet couplings to matter. We point out that, since this symmetry is typically generation-dependent, it gives rise to non-trivial flavor structure. Furthermore, because flavor symmetries cannot be exact, the triplet-matter couplings are not forbidden then but only suppressed. We construct models in which the triplet symmetry gives acceptable proton decay rate and fermion masses. In some of the models, the prediction m_b ~ m_τis retained, while the similar relation for the first generation is corrected. Finally, all this can be accomplished with triplets somewhat below the GUT scale, supplying the right correction for the standard model gauge couplings to unify precisely.

description: The dust- and gas-rich protoplanetary disks around young stellar systems play a key role in star and planet formation. While considerable progress has recently been made in probing these disks on large scales of a few tens of astronomical units (au), the central au needs to be more investigated. We aim at unveiling the physical processes at play in the innermost regions of the strongly accreting T Tauri Star S CrA N by means of near-infrared interferometric observations. The K-band continuum emission is well reproduced with an azimuthally-modulated dusty ring. As the star alone cannot explain the size of this sublimation front, we propose that magnetospheric accretion is an important dust-heating mechanism leading to this continuum emission. The differential analysis of the Hydrogen Br$γ$ line is in agreement with radiative transfer models combining magnetospheric accretion and disk winds. Our observations support an origin of the Br$γ$ line from a combination of (variable) accretion-ejection processes in the inner disk region.

description: Objective: To evaluate new medical devices and drugs pertinent to otolaryngology–head and neck surgery that were approved by the Food and Drug Administration (FDA) in 2021. Data Sources: Publicly available FDA device and drug approvals from ENT (ear, nose, and throat), anesthesia, neurosurgery, plastic surgery, and general surgery FDA committees. Review Methods: FDA device and therapeutic approvals were identified and reviewed by members of the American Academy of Otolaryngology–Head and Neck Surgery’s Medical Devices and Drugs Committee. Two independent reviewers assessed the relevance of devices and drugs to otolaryngologists. Medical devices and drugs were then allocated to their respective subspecialty fields for critical review based on available scientific literature. Conclusions: The Medical Devices and Drugs Committee reviewed 1153 devices and 52 novel drugs that received FDA approval in 2021 (67 ENT, 106 anesthesia, 618 general surgery and plastic surgery, 362 neurosurgery). Twenty-three devices and 1 therapeutic agent relevant to otolaryngology were included in the state of the art review. Advances spanned all subspecialties, including over-the-counter hearing aid options in otology, expanding treatment options for rhinitis in rhinology, innovative laser-safe endotracheal tubes in laryngology, novel facial rejuvenation and implant technology in facial plastic surgery, and advances in noninvasive and surgical treatment options for obstructive sleep apnea. Implications for Practice: FDA approvals for new technology and pharmaceuticals present new opportunities across subspecialties in otolaryngology. Clinicians’ nuanced understanding of the safety, advantages, and limitations of these innovations ensures ongoing progress in patient care.

description: We consider equilibrium statistical mechanics of a simplified model for the ideal conductor electrode in an interface contact with a classical semi-infinite electrolyte, modeled by the two-dimensional Coulomb gas of pointlike $\pm$ unit charges in the stability-against-collapse regime of reduced inverse temperatures $0\le β<2$. If there is a potential difference between the bulk interior of the electrolyte and the grounded interface, the electrolyte region close to the interface (known as the electrical double layer) carries some nonzero surface charge density. The model is mappable onto an integrable semi-infinite sine-Gordon theory with Dirichlet boundary conditions. The exact form-factor and boundary state information gained from the mapping provide asymptotic forms of the charge and number density profiles of electrolyte particles at large distances from the interface. The result for the asymptotic behavior of the induced electric potential, related to the charge density via the Poisson equation, confirms the validity of the concept of renormalized charge and the corresponding saturation hypothesis. It is documented on the non-perturbative result for the asymptotic density profile at a strictly nonzero $β$ that the Debye-Hückel $β\to 0$ limit is a delicate issue.

description: Entwicklungs-, Bildungs- und Sozialisationsprozesse von Heranwachsenden vollziehen sich in pädagogischen Beziehungen. Neben den Beziehungen zu Eltern, weiteren Familienmitgliedern und Peers stellen Beziehungen zu pädagogischen Fachkräften und Lehrkräften wesentliche Gegebenheiten des Aufwachsens in modernen Gesellschaften dar (vgl. Prengel & Winklhofer, 2014, S. 5f.). Dabei ist es sowohl für ihre gegenwärtigen Erfahrungen während der Kindheit als auch für ihre zukünftige Entwicklung bedeutsam, ob sie Pädagog*innen begegnen, die sie anerkennen und ermutigen oder demütigen und verletzen (vgl. Ostermann & Prengel, 2019). Im vorliegenden Beitrag erfolgt ein Einblick in eine empirische Studie über die Qualität der Interaktionen von Lehrkräften mit Kindern, um herauszuarbeiten, auf welche Art und Weise und wie Lehrende die ihnen anvertrauten Kinder in beobachteten Betreuungsphasen anerkennen und verletzen.

description: Verhältnisse der Passung und Unpassung in schulischen Kontexten werden bisher insbesondere im „Schulkulturansatz“ (Böhme, Hummrich & Kramer, 2015, S. 12) in ihrer Anerkennungsbedeutsamkeit betrachtet. Im Fokus stehen dabei vornehmlich Passungsverhältnisse zwischen den Anerkennungsordnungen von Schule bzw. der jeweiligen Schulkultur und den habituellen Prägungen von Schüler*innen. Verhältnisse der habituellen Passung und Unpassung auf der Interaktionsebene zwischen Lehrpersonen und Schüler*innen und damit verbundene anerkennungsrelevante Konsequenzen bilden ein Forschungsdesiderat. Mit den Rekonstruktionen in diesem Artikel wird dieses Desiderat bearbeitet. Ausgehend von Ausschnitten aus Protokollen von bildungsbiographischen Interviews mit (ehemaligen) Schüler*innen werden erzählte Unterrichtssituationen und damit verbundene Erfahrungen der Anerkennung und Nicht-Anerkennung aus Schüler*innensicht in den Blick genommen. Mit der Methode der objektiven Hermeneutik werden habituelle Passungen und Unpassungen zwischen Lehrperson und Schüler*in im Kontext der erzählten Situationen rekonstruiert. Dabei wird gezeigt, inwiefern diese habituellen (Un-)Passungen mit Anerkennungserfahrungen auf Schüler*innenseite verbunden sind und welche bildungsrelevanten Konsequenzen das Zusammenspiel hat. Die Ergebnisse werden nicht nur in ein Verhältnis zur Ebene der Schulkultur gesetzt, sondern auch in ihrer Bildungsgerechtigkeitsrelevanz beleuchtet.

description: We analyze in detail the perturbative decay of the inflaton oscillating about a generic form of its potential $V(ϕ) = ϕ^k$, taking into account the effects of non-instantaneous reheating. We show that evolution of the temperature as a function of the cosmological scale factor depends on the spin statistics of the final state decay products when $k > 2$. We also include the inflaton-induced mass of the final states leading to either kinematic suppression or enhancement if the final states are fermionic or bosonic respectively. We compute the maximum temperature reached after inflation, the subsequent evolution of the temperature and the final reheat temperature. We apply our results to the computation of the dark matter abundance through thermal scattering during reheating. We also provide an example based on supersymmetry for the coupling of the inflaton to matter.

description: Im Artikel werden Überlegungen fortgeführt, die im Rahmen eines Dissertationsprojekts zu Partizipationsprozessen von Schüler*innen in der gymnasialen Oberstufe angestellt wurden. Auf der Basis des praktikentheoretischen Ansatzes der „Anerkennung als …“ werden aus den im Projekt entstandenen Interviews mit Schülervertreter*innen und SV-Lehrkräften Beispiele für Prozesse der Adressierung und Readressierung herausgearbeitet. Diese verweisen auf die Komplexität von Anerkennungsprozessen im schulischen Kontext, aber auch auf ihren Erkenntnisgehalt für das Verständnis kommunikativen Handelns in diesem Rahmen sowie von dessen Effekten auf die Subjektbildung, sowohl von Schüler*innen als auch von Lehrkräften. Zudem werfen sie ein Schlaglicht auf den Bedarf nach einer reflektierten Aufarbeitung von negativen Subjektivierungserfahrungen bei Lehrer*innen und damit auch auf die Professionalisierungsbedarfe von Lehrkräften. Eine reflexive Haltung zu den reziproken Prozessen der Anerkennung könnte die Grundlage dafür sein, im Bewusstsein des eigenen Bedürfnisses nach Anerkennung einen professionellen Umgang auch mit Ablehnung und Abwertung herausbilden. Hierzu müssten neue, auf die Ermöglichung von Reflexivität ausgerichtete Forschungs- und Professionalisierungsformate entwickelt werden.

description: The phenomenon of localization usually happens due to the existence of disorder in a medium. Nevertheless, certain quantum systems allow dynamical localization solely due to the nature of internal interactions. We study a discrete time quantum walker which exhibits disorder free localization. The quantum walker moves on a one-dimensional lattice and interacts with on-site spins by coherently rotating them around a given axis at each step. Since the spins do not have dynamics of their own, the system poses the local spin components along the rotation axis as an extensive number of conserved moments. When the interaction is weak, the spread of the walker shows subdiffusive behaviour having downscaled ballistic tails in the evolving probability distribution at intermediate time scales. However, as the interaction gets stronger the walker gets exponentially localized in the complete absence of disorder in both lattice and initial state. Using a matrix-product-state ansatz, we investigate the relaxation and entanglement dynamics of the on-site spins due to their coupling with the quantum walker. Surprisingly, we find that even in the delocalized regime, entanglement growth and relaxation occur slowly unlike marjority of the other models displaying a localization transition.

description: Signature from Pop III massive stars of $140$--$260\,{\rm M_\odot}$ that end their lives as pair-instability supernovae (PISNe) are expected to be seen in very metal-poor (VMP) stars of ${\rm [Fe/H]}\leq -2$. Although thousands of VMP stars have been discovered, the identification of a VMP star with a PISN signature has been elusive. Recently, the VMP star LAMOST J1010+2358 was claimed to be the first star with a clear PISN signature. A subsequent study showed that ejecta from low-mass core-collapse supernovae (CCSNe) can also fit the abundance pattern equally well and additional elements such as C and Al are required to differentiate the two sources. Follow-up observations of LAMOST J1010+2358 by two independent groups were able to detect both C and Al. Additionally, key odd elements such as Na and Sc were also detected whose abundances were found to be higher than the upper limits found in the original detection. We perform a detailed analysis of the newly observed abundance patterns by exploring various possible formation channels for VMP stars. We find that purely low-mass CCSN ejecta as well as the combination of CCSN and Type 1a SN ejecta can provide an excellent fit to the newly observed abundance pattern. Our results confirm earlier analysis that the newly observed abundance pattern is peculiar but has no signatures of PISN.

Epistemic reasoning and adolescent egocentrism among adolescent boys with behavioral disorders and their peers without behavioral disorders

description: A number of investigations have been conducted to examine social cognition and psychopathology among adolescents, yet little is known about the social cognitive reasoning of adolescents identified as having severe behavioral disorders. The purpose of the present study was to explore the social cognitive reasoning of adolescent boys with behavioral disorders in comparison to their peers without behavioral disorders. Group differences were examined with respect to epistemic reasoning and the dimensions of adolescent egocentrism. In addition, the relation between social cognition and social relationships was investigated. Finally, the relation between social cognition and psychopathology was explored. Thirty-one adolescent boys with behavioral disorders and 32 of their peers without behavioral disorders (matched forage, race, and SES) participated in the study. All participants were individually administered measures designed to assess epistemic reasoning, imaginary audience and personal fable ideation (i.e., invulnerability, omnipotence, personal uniqueness), and personal-intimacy and groupintegration with peers and family. In addition, boys with behavioral disorders completed a measure of internalizing, externalizing, and total problem behaviors. Teacher-ratings of problem behaviors were also completed for each participant in the study. Results revealed that adolescent boys with behavioral disorders were lower in epistemic reasoning than were adolescent boys without behavioral disorders. Groups were not found to differ with respect to imaginary audience or personal fable ideation. For boys with behavioral disorders, no relation was found between social cognition and social relationships. In contrast, for boys without behavioral disorders, personal uniqueness was negatively related to group-integration with peers and omnipotence was positively related to group-integration with family. Social cognitive reasoning was found to predict self-reported problem behaviors for boys with behavioral disorders and teacher-re ported problem behaviors for boys without behavioral disorders. Overall, these results suggest the importance of epistemic reasoning in understanding the relation between social cognition and psychopathology.

description: Objectives: To evaluate new drugs and devices relevant to otolaryngology–head and neck surgery that were approved by the US Food and Drug Administration (FDA) in 2020. Data Sources: Publicly available device and therapeutic approvals from ENT (ear, nose, and throat), anesthesia, neurology (neurosurgery), and plastic and general surgery FDA committees. Review Methods: Members of the American Academy of Otolaryngology–Head and Neck Surgery’s Medical Devices and Drugs Committee reviewed new therapeutics and medical devices from a query of the FDA’s device and therapeutic approvals. Two independent reviewers assessed the drug’s or device’s relevance to otolaryngology, classified to subspecialty field, with a critical review of available scientific literature. Conclusions: The Medical Devices and Drugs Committee reviewed 53 new therapeutics and 1094 devices (89 ENT, 140 anesthesia, 511 plastic and general surgery, and 354 neurology) approved in 2020. Ten drugs and 17 devices were considered relevant to the otolaryngology community. Rhinology saw significant improvements around image guidance systems; indications for cochlear implantation expanded; several new monoclonal therapeutics were added to head and neck oncology’s armamentarium; and several new approvals appeared for facial plastics surgery, pediatric otolaryngology, and comprehensive otolaryngology. Implications for Practice: New technologies and pharmaceuticals offer the promise of improving how we care for otolaryngology patients. However, judicious introduction of innovations into practice requires a nuanced understanding of safety, advantages, and limitations. Working knowledge of new drugs and medical devices approved for the market helps clinicians tailor patient care accordingly.

description: We study the roots of a random polynomial over the field of $p$-adic numbers. For a random monic polynomial with i.i.d. coefficients in $\mathbb{Z}_p$, we obtain an estimate for the expected number of roots of this polynomial. In particular, if the coefficients take the values $\pm1$ with equal probability, the expected number of $p$-adic roots converges to $\left(p-1\right)/\left(p+1\right)$ as the degree of the polynomial tends to $\infty$.

description: We study the relationship between education and fertility, exploiting compulsory schooling reforms in England and Continental Europe, implemented between 1936 and 1975. We assess the causal effect of education on the number of biological children and the incidence of childlessness. We find surprising results for Continental Europe: the additional education generated by compulsory schooling expansions led to an increase in the number of biological children per woman and a decrease in childlessness. The results for England point in the opposite direction. Moreover, for the Continent we find that education during this time led to fewer women who remained unmarried over their life course. Our findings are robust to a number of sensitivity and falsification checks.

description: Recently it was shown that the excess of diffuse Galactic gamma rays above 1 GeV traces the Dark Matter halo, as proven by reconstructing the peculiar shape of the rotation curve of our Galaxy from the gamma ray excess. This can be interpreted as a Dark Matter annihilation signal. In this paper we investigate if this interpretation is consistent with Supersymmetry. It is found that the EGRET excess combined with all electroweak constraints is fully consistent with the minimal mSUGRA model for scalars in the TeV range and gauginos below 500 GeV.
