description: Three-dimensional (3D) kinetic maps of the Milky Way interstellar medium are an essential tool in studies of its structure and of star formation. We aim to assign radial velocities to Galactic interstellar clouds now spatially localized based on starlight extinction and star distances from Gaia and stellar surveys. We developed an automated search for coherent projections on the sky of clouds isolated in 3D extinction density maps on the one hand, and regions responsible for CO radio emissions at specific Doppler shifts on the other hand. The discrete dust structures were obtained by application of the Fellwalker algorithm to a recent 3D extinction density map. For each extinction cloud, a technique using a narrow sliding spectral window moved along the contour-bounded CO spectrum and geometrical criteria was used to select the most likely velocity interval. We applied the new contour-based technique to the 3D extinction density distribution within the volume encompassing the Taurus, Auriga, Perseus and California molecular complexes. From the 45 clouds issued from the decomposition, 42 were assigned a velocity. The remaining structures correspond to very weak CO emission or extinction. We used the non-automated assignments of radial velocities to clouds of the same region presented in paper I and based on KI absorption spectra as a validation test. The new fully automated determinations were found in good agreement with these previous measurements. Our results show that an automated search based on cloud contour morphology can be efficient and that this novel technique may be extended to wider regions of the Milky Way and at larger distance. We discuss its limitations and potential improvements after combination with other techniques.

description: Tourism is one of the principal sectors of the economy that makes an important contribution to the distribution of income in society. Tourist activity has shown great expansion and participation in the economy, while developing in an atmosphere of intense competition and demand on the part of its users. The objective of this research is to analyze tourists perception of the quality of services offered in a cultural tourism attraction in Paraíba. The studied object, located on the coast of João Pessoa - PB, stands out for being a pioneer in the activities offered, since it is the only one that offers cultural and environmental immersion in Brazil having a set of 32 villages of the Potiguara ethnicity. To support the research, studies on the evaluation of services in tourism were adopted, specifically the TOURQUAL Model. The data was obtained through mixed qualitative research on TripAdvisor, and the data was analyzed based on the 28 TOURQUAL indicators. It was noted that the destination was well evaluated, considering the reality of a little explored community-based cultural tourism, since this research is the first carried out in the place, which covers a total of 32 indigenous villages that offer cultural and environmental immersion in the Potiguara ethnic group. The studied destination has a remarkable potential for growth, where in the research, improvements were suggested so that the destination can be more recognized in the national scenario. In addition, the significant engagement of local public bodies stands out, as the destination's initiatives move the local economy, generating income and employment.

description: Electrochemical impedance spectroscopy (EIS) is a widely used experimental technique for characterising materials and electrode reactions by observing their frequency-dependent impedance. Classical EIS measurements require the electrochemical process to behave as a linear time-invariant system. However, electrochemical processes do not naturally satisfy this assumption: the relation between voltage and current is inherently nonlinear and evolves over time. Examples include the corrosion of metal substrates and the cycling of Li-ion batteries. As such, classical EIS only offers models linearised at specific operating points. During the last decade, solutions were developed for estimating nonlinear and time-varying impedances, contributing to more general models. In this paper, we review the concept of impedance beyond linearity and stationarity, and detail different methods to estimate this from measured current and voltage data, with emphasis on frequency domain approaches using multisine excitation. In addition to a mathematical discussion, we measure and provide examples demonstrating impedance estimation for a Li-ion battery, beyond linearity and stationarity, both while resting and while charging.

description: Hintergrund:  In internationalen Studien konnte mehrfach der Zusammenhang zwischen Arbeitslosigkeit und einem schlechteren Gesundheitszustand nachgewiesen werden. Allerdings fehlen Untersuchungen bezüglich der Kommunikationserfahrung von Menschen mit Migrationshintergrund über Arbeitslosigkeit in Hausarztpraxen in Deutschland.
 Methoden:  Für diese Studie wurden Daten aus der Gesundheitsbefragung zur Gesundheit Erwachsener in Deutschland (DEGS1) 2008-2011(N= 5938) und Daten aus der Patientenbefragung GP-Care 1 2020 (N= 813) verwendet. Statistische Methoden umfassten lineare Regressionsmodelle zum Zusammenhang zwischen Stress, Arbeitslosigkeit und Migrationshintergrund. Ergänzende Reverse Proportional Odds Modelle analysierten den Zusammenhang zwischen Migrationshintergrund, Arbeitslosigkeit und Kommunikationserfahrung in Hausarztpraxen.
 Ergebnisse:  In dieser Studie zeigte sich, dass Migrationshintergrund und Arbeitslosigkeitserfahrung mit einem erhöhten Stresslevel assoziiert sind (p < 0,01). Zudem besteht eine verminderte Zufriedenheit mit der hausärztlichen Kommunikation bezüglich sozialer Schwierigkeiten. Arbeitslose Menschen mit Migrationshintergrund stimmten der Aussage, dass ihr Arzt ihnen genug Raum gibt, um ihre Probleme zu schildern (46,5% vs. 58,2%; p = 0,03), und der Aussage, dass sie das Gefühl haben, dass ihre Probleme ernst genommen werden, weniger häufig zu (50,8% vs. 73,8%; p = 0,04). In multivariaten Analysen konnte Migrationshintergrund, nicht jedoch Arbeitslosigkeitserfahrung als unabhängiger Risikofaktor für eine weniger zufriedenstellende Kommunikation in der Hausarztpraxis bestätigt werden.

description: The quasi-normal mode (QNM) spectrum of black holes is unstable under small perturbation of the potential and has observational consequences in time signals. Such signals might be experimentally difficult to observe and probing this instability will be a technical challenge. Here we investigate the spectral instability of time-independent data. This leads us to study the Regge Poles (RP), the counterparts to the QNMs in the complex angular momentum plane. We present evidence that the RP spectrum is unstable but that not all overtones are affected equally by this instability. In addition, we reveal that behind this spectral instability lies an underlying structure. The RP spectrum is perturbed in such a way that one can still recover stable scattering quantities using the complex angular momentum approach. Overall, the study proposes a novel and complementary approach on the black hole spectral instability phenomena which allows us to reveal a surprising and unexpected mechanism at play which protects scattering quantities from the instability.

description: Recent breakthroughs in NLP largely increased the presence of ASR systems in our daily lives. However, for many low-resource languages, ASR models still need to be improved due in part to the difficulty of acquiring pertinent data. This project aims to help advance research in ASR models for Swiss German dialects, by providing insights about the performance of state-of-the-art ASR models on recently published Swiss German speech datasets. We propose a novel loss that takes into account the semantic distance between the predicted and the ground-truth labels. We outperform current state-of-the-art results by fine-tuning OpenAI's Whisper model on Swiss-German datasets.

description: Gastronomy can be considered a key aspect of an intangible cultural asset and is included in the Livro de Registro dos Saberes (Knowledge Record Book) of the Instituto do Patrimônio Histórico e Artístico Nacional (National Historic and Artistic Heritage Institute) in Brazil. Brazilian gastronomic traditions are considered as a large set of sociocultural practices and in simple dishes, food and production habits from many generations are attributed. In this way, the aspects of identity inherent to social transitions between communities, generating the feeling of belonging among social groups, which until then saw these habits as a simple means of subsistence, are currently an attraction of great influence in the tourist, cultural and geographical field. Gastronomy is a way of connecting social relationships and, within its methods, thoughts and protocols are contained, aggregating knowledge from different times. From the study of gastronomy, in its vast themes, it is possible to understand that in Brazil there are still many heritage treasures to be discovered, adding them to our mixed cultural structure. Thus, this research aimed to recognize from the point of view of gastronomy the expertise of making cassava flour as an intangible cultural heritage of the state of Piauí, being a relevant activity for the subsistence of many communities such as the village of Canto Grande, in the municipality of Cajueiro da Praia, in the state of Piauí. The methodology adopted was based on bibliographic research in books and scientific articles, in addition to participatory observation, in the context of the production processes of the cassava flour in the village of Canto Grande, providing information about the diversified method of production and the materials and tools used by this community located in the northern part of Piauí.

description: The relationship between transportation and tourism is inseparable, and both are services that provide user experiences. The systemic view has been paradigmatic for the treatment of this interface. However new approaches have emerged, including others based on the larger web of mobility. In order to create a new research agenda on Transportation and Tourism involving Brazil, it is necessary to investigate the scientific production to verify the state of the art, which is the main objective of this study. This research is exploratory and descriptive of a qualitative nature, and it was carried out through a bibliographic survey and software support was used for the spreadsheet, textual and geographical approaches. As for the results, on the one hand, this snapshot allows us to understand the epistemological advances. On the other hand, it provides indications for these advances to be incorporated into the discussions on planning and management of transportation and Brazilian tourist destinations, constituting premises of the Applied Social Sciences. Besides, from the state of the art identified, it is possible to launch new interdisciplinary perspectives on the future of research, proposing a strategic agenda for research in tourism and transportation, based on creativity and innovation in both the theoretical and methodological fields.

description: Inspired by the observation of a resonant state $X(6600)$ of fully charm tetraquark by the CMS experiment of LHCb Collaboration in double $J/ψ$ decay channel, we perform a systematical study of all configurations of fully heavy pentaquarks $P_{Q_{1}Q_{2}Q_{3}Q_{4}\bar{Q_{5}}}$ ($Q_{i}=c,b$%, $i=1,2,3,4,5$) in their ground states in unified framework of MIT bag model. The color-spin wavefunctions of pentaquarks, classified via Young tableau and presented in terms of the Young-Yamanouchi bases, are used to compute masses and magnetic moments of fully heavy pentaquarks via numerical variational method, predicting a set of masses ranging from $8.229$ GeV for the $P_{cccc\bar{c}}$ to $24.770$ GeV for the $P_{bbbb\bar{b}}$. Combining with computed masses of fully heavy mesons and baryons, we find that masses of fully heavy hadrons(mesons, baryons, tetraquarks and pentaquarks) with identical flavor rise almost linearly with the number of valence quarks in hadrons, being consistent with the heavy quark symmetry in the heavy-quark limit.

description: Context. Giant planets play a major role in multiple planetary systems. Knowing their demographics is important to test their overall impact on planetary systems formation. It is also important to test their formation processes. Recently, three radial velocity surveys have established radial distributions of giant planets. All show a steep increase up to 1-3 au, and two suggest a decrease beyond. Aims. We aim at understanding the limitations associated with the characterization of long-period giant radial velocity planets, and to estimate their impact on the radial distribution of these planets. Methods. We revisit the results obtained by two major surveys that derived such radial distributions, using the RV data available at the time of the surveys as well as, whenever possible, new data. Results. We show that the radial distributions published beyond (5-8 au) are not secure. More precisely, the decrease of the radial distribution beyond the peak at 1-3 au is not confirmed.

description: The ways of narrating the journey have become a great way in the early 21st century. They left behind the chatting circles, the film productions, the books and gained space on the Internet. This research aims to know how social networks are used by content creators (bloggers and influencers in the tourism industry) to record the trip and reflect on how the pedagogies in these spaces teach different ways of traveling. For the treatment and data analysis, content analysis was performed. The way of carrying out the research was inspired by the studies developed in Cultural Studies and based on various sources whose composition or content related to traveling, such as books, magazines, websites, and, mainly, blogs and social networks. Among the several authors studied, we highlight the research conducted on the different manifestations of the “self” in contemporary times, among them, texts by Zygmunt Bauman (2008), Gilles Lipovetsky (2016) and especially Byung-Chul Han (2015, 2016). The main results highlight that, in contemporaneity, the consumption of travel reports once made through books, technical magazine articles, documentaries, and even blogs were gradually being replaced by practical tips - which fit in spaces standardized by the creators of social networks such as Facebook and Instagram. In these spaces, users are educated to look at places in fragments. Ready-made lists and itineraries reduce cities to some landmarks. In addition, in these same “spaces,” the travel becomes a stage and the landscapes into scenarios for the most diverse representations, reinforcing the ideas of an ephemeral, transparent, volatile, individualistic, and accelerated life that mark them and teach recipes for traveling that ends up repeating itself on the screens.

description: This study developed a novel method for detecting hypernuclear events recorded in nuclear emulsion sheets using machine learning techniques. The artificial neural network-based object detection model was trained on surrogate images created through Monte Carlo simulations and image-style transformations using generative adversarial networks. The performance of the proposed model was evaluated using $α$-decay events obtained from the J-PARC E07 emulsion data. The model achieved approximately twice the detection efficiency of conventional image processing and reduced the time spent on manual visual inspection by approximately 1/17. The established method was successfully applied to the detection of hypernuclear events. This approach is a state-of-the-art tool for discovering rare events recorded in nuclear emulsion sheets without any real data for training.

PRECARISATION OF LABOUR

description: This study discusses the issues of hijacking and capturing subjectivity under manipulative capitalism in the current labour conditions and relations in the tourism economy. In this sense, it points out to the structural trend of precarisation of labour among travel agents, even more aggravated by the demand for high professional qualification and excellence in services. There is a certain adjustment of the worker to the company's imaginary; a feeling of indispensability and worthiness for effort and merit; adhesion and involvement with the organizational whole, materialized by teamwork; belief in effective collaboration at work; and feeling of self-delivery, self-giving and selfcommitment. This implies a labour context of intense imposition of conduct on workers, who need to demonstrate sympathetic and total personality engagement for the reproduction of capital, despite the precariousness of working conditions and relationships in many sectors of tourism activity.

description: The atomic hydrogen (HI) properties of star-forming galaxies in the local Universe are known to correlate with other galaxy properties via the ``HI scaling relations''. The redshift evolution of these relations serves as an important constraint on models of galaxy evolution. However, until recently, there were no estimates of the HI scaling relations at cosmological distances. Using data from a deep Giant Metrewave Radio Telescope HI 21 cm survey of the Extended Groth Strip, and the technique of spectral line stacking, we determine the scaling relation between the HI mass and the stellar mass for star-forming galaxies at $z\approx0.35$. We use this measurement, along with the main-sequence relation in galaxies, to infer the dependence of the HI depletion timescale of these galaxies on their stellar mass. We find that massive star-forming galaxies at $z\approx0.35$, with stellar mass $\rm M_* \gtrsim10^{9.5}\:M_{\odot}$, are HI-poor compared to local star-forming galaxies of a similar stellar mass. However, their characteristic HI depletion time is lower by a factor of $\approx 5$ than that of their local analogues, indicating a higher star-formation efficiency at intermediate redshifts (similar to that at $z \approx 1$). While our results are based on a relatively small cosmic volume and could thus be affected by cosmic variance, the short characteristic HI depletion timescales ($\lesssim 3$ Gyr) of massive star-forming galaxies at $z \approx 0.35$ indicate that they must have acquired a significant amount of neutral gas through accretion from the circumgalactic medium over the past four Gyr, to avoid quenching of their star-formation activity.

description: The study of $J/ψ$ photoproduction at low energies has consequences for the understanding of multiple aspects of nonperturbative QCD, ranging from mechanical properties of the proton, to the binding inside nuclei, and the existence of hidden-charm pentaquarks. Factorization of the photon-$c \bar c$ and nucleon dynamics or Vector Meson Dominance are often invoked to justify these studies. Alternatively, open charm intermediate states have been proposed as the dominant mechanism underlying $J/ψ$ photoproduction. As the latter violates this factorization, it is important to estimate the relevance of such contributions. We analyse the latest differential and integrated photoproduction cross sections from the GlueX and $J/ψ$-007 experiments. We show that the data can be adequately described by a small number of partial waves, which we parameterize with generic models enforcing low-energy unitarity. The results suggest a nonnegligible contribution from open charm intermediate states. Furthermore, most of the models present an elastic scattering length incompatible with previous extractions based on Vector Meson Dominance, and thus call into question its applicability to heavy mesons. Our results indicate a wide array of physics possibilities that are compatible with present data and need to be disentangled.

description: Low-luminosity supermassive and stellar-mass black holes (BHs) may be embedded in a collisionless and highly magnetized plasma. They show non-thermal flares indicative of efficient dissipative processes in the vicinity of the BH. During NIR flares from the supermassive BH Sagittarius A* (Sgr A*), GRAVITY detected circular motion and polarization evolution which suggest the presence of transient synchrotron-emitting hot spots moving around the BH. We study 3D reconnecting current layers in the magnetosphere of spinning BHs to determine whether plasma-loaded flux ropes formed near the event horizon could reproduce the hot spot observations and help constraining the BH spin. We perform global 3D particle-in-cell simulations in Kerr spacetime of a pair plasma embedded in a strong large-scale magnetic field originating in a disk in prograde Keplerian rotation. A cone-shaped current layer develops which surrounds the twisted open magnetic field lines threading the event horizon. Magnetic field lines coupling the disk to the BH inflate and reconnect a few gravitational radii above the disk. Particles accelerate and accumulate in a few rotating macroscopic flux ropes. Once flux ropes detach, they propagate in the current layer following what appears as a rapidly opening spiral when seen face-on. A single flux rope carries enough relativistic particles to emit synchrotron radiation at levels suitable to reproduce the flares' peak-luminosity of Sgr A* but it quickly fades away as it flows away. Our kinematic analysis of flux ropes' motion favors a BH spin of 0.65 to 0.8 for Sgr A*. The flares' duration require that the underlying magnetic loop seeded in the disk mid-plane has a finite lifetime and azimuthal extent. In this scenario, the hot spot corresponds to a spinning arc along which multiple reconnection sites power the net emission as flux ropes episodically detach.

description: Cell lineage statistics is a powerful tool for inferring cellular parameters, such as division rate, death rate or the population growth rate. Yet, in practice such an analysis suffers from a basic problem: how should we treat incomplete lineages that do not survive until the end of the experiment? Here, we develop a model-independent theoretical framework to address this issue. We show how to quantify fitness landscape, survivor bias and selection for arbitrary cell traits from cell lineage statistics in the presence of death, and we test this method using an experimental data set in which a cell population is exposed to a drug that kills a large fraction of the population. This analysis reveals that failing to properly account for dead lineages can lead to misleading fitness estimations. For simple trait dynamics, we prove and illustrate numerically that the fitness landscape and the survivor bias can in addition be used for the non-parametric estimation of the division and death rates, using only lineage histories. Our framework provides universal bounds on the population growth rate, and a fluctuation-response relation which quantifies the reduction of population growth rate due to the variability in death rate. Further, in the context of cell size control, we obtain generalizations of Powell's relation that link the distributions of generation times with the population growth rate, and show that the survivor bias can sometimes conceal the adder property, namely the constant increment of volume between birth and division.

description: Nonlinearity has enabled energy harvesting to advance towards higher power output and broader bandwidth in monostable, bistable, and multistable systems. However, challenges in operating in the high energy orbit (HEO) rather than low energy orbit (LEO) have restricted their applications. Based on a monostable nonlinear system, this paper proposes a self-contained solution for time-sharing orbit jump and energy harvesting. The joint dynamics of an electromechanical assembly consisting of a nonlinear energy harvester and a switch-mode piezoelectric interface circuit is studied for high-capability energy harvesting. The proposed solution is carried out by utilizing a cutting-edge switch-mode bidirectional energy conversion circuit (BECC), which enables time-sharing dual functions of energy harvesting and vibration exciting. A theoretical model is established based on impedance analysis and multiple time scales method to analyze the stability, frequency response, and phase evolution of the autonomous and nonautonomous nonlinear energy harvesting systems. Particularly, the detailed dynamics for the orbit jumps with vibration exciting mode of BECC are studied. Experiments are performed to validate the full-range orbit jumps with the monostable nonlinear energy harvester. The harvested power after orbit jumps yields a nine-fold increase, compensating for the energy consumption under vibration exciting mode quickly. The proposed solution also refrains the system from extra mechanical or electrical energy sources for orbit jumps, which leads to the first self-contained solution for simultaneous energy harvesting and orbit jump in nonlinear piezoelectric energy harvesting. This work enhances the practical utility of nonlinear energy harvesting technologies toward engineering applications.

description: Quadruped robots are machines intended for challenging and harsh environments. Despite the progress in locomotion strategy, safely recovering from unexpected falls or planned drops is still an open problem. It is further made more difficult when high horizontal velocities are involved. In this work, we propose an optimization-based reactive Landing Controller that uses only proprioceptive measures for torque-controlled quadruped robots that free-fall on a flat horizontal ground, knowing neither the distance to the landing surface nor the flight time. Based on an estimate of the Center of Mass horizontal velocity, the method uses the Variable Height Springy Inverted Pendulum model for continuously recomputing the feet position while the robot is falling. In this way, the quadruped is ready to attain a successful landing in all directions, even in the presence of significant horizontal velocities. The method is demonstrated to dramatically enlarge the region of horizontal velocities that can be dealt with by a naive approach that keeps the feet still during the airborne stage. To the best of our knowledge, this is the first time that a quadruped robot can successfully recover from falls with horizontal velocities up to 3 m/s in simulation. Experiments prove that the used platform, Go1, can successfully attain a stable standing configuration from falls with various horizontal velocity and different angular perturbations.

title: Valine derived poly (acetylenes) as versatile chiral lyotropic liquid crystalline alignment media for RDC‐based structure elucidations
Creators: name: Krupp, Alexis

description: Anisotropic samples of lyotropic liquid crystalline (LLC) phases of valine derived polyaryl acetylenes were employed as chiral alignment media for the measurement of residual dipolar couplings (RDCs) of 12 small, chiral, organic molecules. The quadrupolar splitting of the deuterium signal of CDCl₃ can be adjusted by temperature and concentration changes from 0 to 350 Hz. The LLC phases showed excellent orienting properties for all analytes bearing various functional groups. The precise extraction of RDCs in the range of up to ±30 Hz from F2‐coupled HSQC spectra was possible. Additionally, the chiral environment led to diastereomorphous interactions with the enantiomers of chiral analytes leading to two different sets of RDCs. This differential order effect was particularly pronounced with H‐bond donors like alcohols and 2° amines.

description: We investigate the stability of MnPb$_{2}$Bi$_{2}$Te$_{6}$ (MPBT), which is predicted to be a magnetic topological insulator (TI), using density functional theory calculations. Our analysis includes various measures such as enthalpies of formation, Helmholtz free energies, defect formation energies, and dynamical stability. Our thermodynamic analysis shows that the phonon contribution to the energy gain from finite temperature is estimated to be less than 10~meV/atom, which may not be sufficient to stabilize MPBT at high temperatures, even with the most favorable reactions starting from binaries. While MPBT is generally robust against the formation of various defects, we find that anti-site defect formation of $\text{Mn}_{\text{Pb}}$ is the most likely to occur, with corresponding energy less than 60~meV. This can be attributed to the significant energy cost from compressive strain at the PbTe layer. Our findings suggest that MPBT is on the brink of stability in terms of thermodynamics and defect formation, underscoring the importance of conducting systematic analyses of the stability of proposed TIs, including MPBT, for their practical utilization. This study offers valuable insights into the design and synthesis of desirable magnetic TI materials with robust stabilities.

description: We develop a frequency-domain method for calculating the self-force acting on a scalar charge on a fixed scattering geodesic in Schwarzschild spacetime. Existing frequency-domain methods, which are tailored for bound orbits, are inadequate here for several reasons. One must account for the continuous spectrum in the scattering problem, deal with slowly-convergent radial integrals that are hard to evaluate numerically, and confront the inapplicability of the standard self-force method of "extended homogeneous solutions", which only works for compactly supported sources. We tackle each of these issues in turn, and then present a full numerical implementation, in which we calculate the self-force correction to the scatter angle due to scalar-field back-reaction. We perform a range of internal validation tests, as well as ones based on comparison with existing time-domain results. We discuss the merits and remaining limitations of our method, and outline directions for future work.

description: The integration of generative AI in the field of education is actively being explored. In particular, ChatGPT has garnered significant interest, offering an opportunity to examine its effectiveness in English as a foreign language (EFL) education. To address this need, we present a novel learning platform called RECIPE (Revising an Essay with ChatGPT on an Interactive Platform for EFL learners). Our platform features two types of prompts that facilitate conversations between ChatGPT and students: (1) a hidden prompt for ChatGPT to take an EFL teacher role and (2) an open prompt for students to initiate a dialogue with a self-written summary of what they have learned. We deployed this platform for 213 undergraduate and graduate students enrolled in EFL writing courses and seven instructors. For this study, we collect students' interaction data from RECIPE, including students' perceptions and usage of the platform, and user scenarios are examined with the data. We also conduct a focus group interview with six students and an individual interview with one EFL instructor to explore design opportunities for leveraging generative AI models in the field of EFL education.

description: The compact size, scalability, and strongly confined fields in integrated photonic devices enable new functionalities in photonic networking and information processing, both classical and quantum. Gallium phosphide (GaP) is a promising material for active integrated photonics due to its high refractive index, wide band gap, strong nonlinear properties, and large acousto-optic figure of merit. In this work we demonstrate that silicon-lattice-matched boron-doped GaP (BGaP), grown at the 12-inch wafer scale, provides similar functionalities as GaP. BGaP optical resonators exhibit intrinsic quality factors exceeding 25,000 and 200,000 at visible and telecom wavelengths respectively. We further demonstrate the electromechanical generation of low-loss acoustic waves and an integrated acousto-optic (AO) modulator. High-resolution spatial and compositional mapping, combined with ab initio calculations indicate two candidates for the excess optical loss in the visible band: the silicon-GaP interface and boron dimers. These results demonstrate the promise of the BGaP material platform for the development of scalable AO technologies at telecom and provide potential pathways toward higher performance at shorter wavelengths.

description: The cosmological principle has been verified using electromagnetic (EM) observations. However its verification with high accuracy is challenging due to various foregrounds and selection effects, and possible violation of the cosmological principle has been reported in the literature. In contrast, gravitational wave (GW) observations are free of these foregrounds and related selection biases. This may enable future GW experiments to test the cosmological principle robustly with full sky distribution of millions of standard bright/dark sirens. However, the sensitivities of GW detectors are highly anisotropic, resulting in significant instrument induced anisotropies in the observed GW catalog. We investigate these instrumental effects for 3rd generation detector networks in term of multipoles $a_{\ell m}$ of the observed GW source distribution, using Monte Carlo simulations. (1) We find that the instrument induced anisotropy primarily exists at the $m=0$ modes on large scales ($\ell \lesssim 10$), with amplitude $\langle |a_{\ell 0}|^2 \rangle \sim 10^{-3}$ for two detectors (ET-CE) and $\sim 10^{-4}$ for three detectors (ET-2CE). This anisotropy is correlated with the sky distribution of signal-to-noise ratio (SNR) and localization accuracy. Such anisotropy sets a lower limit on the detectable cosmological $a_{\ell 0}$. (2) However, we find that the instrument induced anisotropy is efficiently canceled by rotation of the Earth in $m\neq 0$ components of $a_{\ell m}$. Therefore $a_{\ell m}$ ($m\neq 0$) are clean windows to detect cosmological anisotropies. (3) We investigate the capability of 3rd generation GW experiments to measure the cosmic dipole. Through Monte Carlo simulations, we find that cosmic dipole with an amplitude of $\sim 10^{-2}$ reported in the literature can be detected/ruled out by ET-CE and ET-2CE robustly, through the measurement of $a_{11}$.
