description: Oregon fairy shrimp (Eubranchipus oregonus) are freshwater invertebrates that inhabit small temporary ponds in Pacific Spirit Regional Park. This species is at moderate risk of extinction and is known to exist at only one other site in the Lower Mainland. Recently, Metro Vancouver Regional Parks (MVRP) and the Pacific Spirit Park Society (PSPS) concluded a project to expand Oregon fairy shrimp habitat within a region of the park previously logged in 1951. The habitat restoration project involved the removal of invasive plant species over many months, excavation of four shallow vernal ponds, volunteer planting events and translocations of fairy shrimp obtained from one of the two established populations in the park. The translocations were conducted in two phases including a cyst translocation for the Northwest (NW) and Southwest (SW) ponds in September 2021 (Phase I) and an adult translocation for the Northeast (NE) and Southeast (SE) ponds in February 2022 (Phase II). This report describes the short-term results of the restorative work with reference to the success of the translocated fairy shrimp populations, the abiotic parameters of the ponds (pH, depth, dissolved oxygen and temperature) and the state of the terrestrial vegetation around the ponds.

description: Das Zusammenspiel zwischen Bloch-Oszillationen und zeitperiodischer Modulation in räumlich inhomogenen optischen Gittern führt zu einer Vielzahl faszinierender dynamischer Phänomene. Durch theoretische Modellierung und numerische Simulationen zeigen wir zunächst, durch ein globales parabolisches Potential zusätzlich zu einem optischen Gitter eine räumliche Inhomogenität induziert, die traditionelle Bloch-Oszillationen verändert und neue Quanteneffekte wie Kollaps und Revival sowie dynamisches Tunneln von Wellenpaketen hervorruft. Zweitens offenbart diese Studie durch den Einsatz einer zeitperiodischen Modulation der parabolischen Falle weitere Modifikationen der Bloch-Oszillationen im inhomogenen System und eine Vielzahl unterschiedlicher dynamischer Effekte, die als Folge der Modulation auftreten. Die Floquet-Theorie bietet einen geeigneten Zugang, um diese Einteilchen-Bloch-Dynamik in getriebenen Gittern zu verstehen und vorherzusagen und ermöglicht tiefgehende Einblicke in die Kontrolle und die Manipulation von Quantenzuständen in maßgeschneiderten Potentiallandschaften.
description: The interplay between Bloch oscillations and time-periodic modulation in spatially-inhomogeneous optical lattices leads to a rich variety of fascinating dynamical phenomena. Through theoretical modeling and numerical simulations, we first demonstrate that the spatial inhomogeneity induced by a global parabolic trap over an optical lattice modifies traditional Bloch oscillations, introducing new quantum effects such as collapse and revival and dynamical tunneling of wave packets. Secondly, by employing a time-periodic modulation of the parabolic trap, this study reveals further modifications of Bloch oscillations in the inhomogeneous system and a rich variety of contrasting dynamical behaviors that emerge as a consequence of the modulation. Floquet theory provides a powerful framework for understanding and predicting these single-particle Bloch dynamics in driven lattices, offering deep insights into the control and manipulation of quantum states in spatially and temporally engineered potential landscapes.

description: Human-in-the-loop control for mobile robots is an important aspect of robot operation, especially for navigation in unstructured environments or in the case of unexpected events. However, traditional paradigms of human-in-the-loop control have relied heavily on the human to provide precise and accurate control inputs to the robot, or reduced the role of the human to providing supervisory task specifications. In this thesis, we explore a new paradigm of human-robot collaboration called human-in-the-loop planning, where the robot can act semi-autonomously according to the human’s intention while having the human directly inform motion planning and trajectory generation. The proposed paradigm maximizes the strengths of the human and robot such that the human-robot system can perform with optimal efficiency.
 To this end, we first abstract away complex vehicle dynamics by way of motion primitive teleoperation, which allows an operator to control a vehicle via input reparameterization into trajectories. We then build upon motion primitive teleoperation and present a method for reactive collision avoidance. We then propose a novel method of local trajectory generation without end goal specifications for human-in-the-loop control. The method, called Biased Incremental Action Sampling, is a sample based approach to build motion primitive trees that optimize for non-goal based cost functions. We then introduce hierarchical human-in-the-loop planning, which incorporates intended motions as global paths such that generated local trajectories can follow the paths autonomously. Lastly, we introduce continuous dynamic autonomy by generating path predictions on semantic topological navigation maps. By incorporating environment contexts into human-in-the-loop control, this allows us to reason about the human’s intentions over the path space and generate predictions to assist navigation in unstructured, constrained environments.

description: The generative paradigm has become increasingly important in machine learning and deep learning models. Among popular generative models are normalizing flows, which enable exact likelihood estimation by transforming a base distribution through diffeomorphic transformations. Extending the normalizing flow framework to handle time-indexed flows gave dynamic normalizing flows, a powerful tool to model time series, stochastic processes, and neural stochastic differential equations (SDEs). In this work, we propose a novel variant of dynamic normalizing flows, a Time Changed Normalizing Flow (TCNF), based on time deformation of a Brownian motion which constitutes a versatile and extensive family of Gaussian processes. This approach enables us to effectively model some SDEs, that cannot be modeled otherwise, including standard ones such as the well-known Ornstein-Uhlenbeck process, and generalizes prior methodologies, leading to improved results and better inference and prediction capability.

description: Recently, it is proven that positive harmonic functions defined in the unit disc or the upper half-plane in $\mathbb{C}$ are contractions in hyperbolic metrics \cite{Markovic}. Furthermore, the same result does not hold in higher dimensions as shown by given counterexamples \cite{Melentijevic-P}. In this paper, we shall show that positive (or bounded) harmonic functions defined in the unit ball in $\mathbb{R}^{n}$ are Lipschitz in hyperbolic metrics. The involved method in main results allows to establish essential improvements of Schwarz type inequalities for monogenic functions in Clifford analysis \cite{Zhang14,Zhang16} and octonionic analysis \cite{Wang-Bian-Liu} in a unified approach.

A Literature Review Study of Self-Assessment in Music Education
Creators: name: Yang, Bo
Publisher: name: Carnegie Mellon University
Year: 2022
Subjects: Education

description: With the purpose of improving the self-learning processes of young musicians, this study is an analysis of literature on self-assessment in music education including (a) literature that shows that self-assessment encourages personal learning and selfdevelopment; (b) self-assessment used to promote self-regulation in learning and the connection between them; (c) effectiveness of self-assessment in music education. Self-assessment is defined by Koutsoupidou (2010) as a method students and teachers can use to re-think their learning process and be more conscious of their strengths and limitations. This thesis explores the literature on self-assessment in music education. I analyzed the literature of self-assessment both in the area of general education and music education. I adopted Zimmerman’s Self-Regulated Learning as the theoretical framework to explore the relationship between self-assessment, metacognition, and self-regulation, and identify the effectiveness of self-assessment. The findings of this study show that self-assessment has limitations during the evaluation process, but may be key in the development of students as life-long learners.

description: We provide a construction for the kromatic symmetric function $\overline{X}_G$ of a graph introduced by Crew, Pechenik, and Spirkl using combinatorial (linearly compact) Hopf algebras. As an application, we show that $\overline{X}_G$ has a positive expansion into multifundamental quasisymmetric functions. We also study two related quasisymmetric $q$-analogues of $\overline{X}_G$, which are $K$-theoretic generalizations of the quasisymmetric chromatic function of Shareshian and Wachs. We classify exactly when one of these analogues is symmetric. For the other, we derive a positive expansion into symmetric Grothendieck functions when $G$ is the incomparability graph of a natural unit interval order.

description: Recently, a static spherically symmetric black hole solution was found in gravity nonminimally coupled a background Kalb-Ramond field. The Lorentz symmetry is spontaneously broken when the Kalb-Ramond field has a nonvanishing vacuum expectation value. In this work, we focus on the quasinormal modes and greybody factor of this black hole. The master equations for the perturbed scalar field, electromagnetic field, and gravitational field can be written into a uniform form. We use three methods to solve the quasinormal frequencies in the frequency domain. The results agree well with each other. The time evolution of a Gaussian wave packet is studied. The quasinormal frequencies fitted from the time evolution data agree well with that of frequency domain. The greybody factor is calculated by Wentzel-Kramers-Brillouin (WKB) method. The effect of the Lorentz-violating parameter on the quasinormal modes and greybody factor are also studied.

description: In fulfilling the European security commitment, the actors of the so-called "Intelligence Community" play a central role. They provide political and military decision-makers with important analyses and information. The Intelligence College in Europe (ICE) is the first entity to offer professional intelligence training as well as postgraduate level academic education in intelligence and security studies at a pan-European level. In developing its postgraduate provision, ICE has benefited from the experience of the German Master of Intelligence and Security Studies (MISS), which is a joint effort of the University of the Bundeswehr Munich and the Department of Intelligence at the Federal University of Administrative Sciences in Berlin. As a main contribution of this paper, the module Counterterrorism (adapted from the MISS) is examined in more detail as a case study of how postgraduate modules can be modified to speak to a pan-European audience of intelligence professionals.
description: 10 pages, 2 figures. Our experience with the MISS (especially for the Master of Science degree) has shown that three aspects are important in ICE: first, transdisciplinarity; second, the integration of profound IT know-how; and third, the development and learning of methodological skills

description: We report unbiased AI measurements of the fine structure constant $α$ in two proximate absorption regions in the spectrum of the quasar HE0515$-$4414. The data are high resolution, high signal to noise, and laser frequency comb calibrated, obtained using the ESPRESSO spectrograph on the VLT. The high quality of the data and proximity of the regions motivate a differential comparison, exploring the possibility of spatial variations of fundamental constants, as predicted in some theories. We show that if the magnesium isotopic relative abundances are terrestrial, the fine structure constants in these two systems differ at the 7$σ$ level. A 3$σ$ discrepancy between the two measurements persists even for the extreme non-terrestrial case of 100\% $^{24}$Mg, if shared by both systems. However, if Mg isotopic abundances take independent values in these two proximate systems, one terrestrial, the other with no heavy isotopes, both can be reconciled with a terrestrial $α$, and the discrepancy between the two measurements falls to 2$σ$. We cannot rule out other systematics that are unaccounted for in our study that could masquerade as a varying alpha signal. We discuss varying constant and varying isotope interpretations and resolutions to this conundrum for future high precision measurements.

description: The time evolution of a wave packet is a tool to detect topological phase transitions in two-dimensional Dirac materials, such as graphene and silicene. Here we extend the analysis to HgTe/CdTe quantum wells and study the evolution of their electron current wave packet, using 2D effective Dirac Hamiltonians and different layer thicknesses. We show that the two different periodicities that appear in this temporal evolution reach a minimum near the critical thickness, where the system goes from normal to inverted regime. Moreover, the maximum of the electron current amplitude changes with the layer thickness, identifying that current maxima reach their higher value at the critical thickness. Thus, we can characterize the topological phase transitions in terms of the periodicity and amplitude of the electron currents.

Contactless Measurements of Metal-Insulator Transitions using Toroidal Loop-Gap Resonators
Creators: name: Kennedy, Ian R.
Publisher: name: The University of British Columbia
Year: 2022

description: We have used a toroidal loop-gap resonator (TLGR) to make sensitive contactless mea- surements of the so-called Verwey transition in Fe₃O₄ (magnetite) at microwave frequencies. In this metal-insulator transition, the sample’s resitivity increases by up to two orders of magnitude as it is cooled below 120 K. In our project a single-crystal sample of Fe₃O₄ is suspended in the bore of the TLGR. Microwave power absorption by the sample lowers the quality factor of the measured resonance. The observed changes in the quality factor are used to determine the temperature dependence of the sample’s resistivity. This project presents a characterization of the TLGR, design features of the low-temperature apparatus, the experimental results, as well as future considerations.

description: Um die heterogenen Strukturen des gärtnerischen Einzelhandels aus Sicht des Dienstleistungsprogramms zu entflechten, ist das systematische Herausarbeiten von situativen Einflussgrößen ein möglicher Ansatz. Hierzu wurde ein exploratives Vorgehen gewählt. Unter Verwendung einer qualitativen Inhaltsanalyse ergeben sich neben der Organisationsform und der Unternehmensgröße vor allem einzelne Variablen des Leistungsspektrums, die sich aus der Anzahl reiner Dienstleistungsabteilungen/eigenständiger Dienstleistungsbetriebe, der Dienstleistungserfahrung und der Dienstleistungsart zusammensetzen. Die Ermittlung dieser Einflussgrößen ermöglicht eine erste Klassifizierung in einzelhandels- und dienstleistungsorientierte Betriebstypen vorzunehmen und bildet die Ausgangsbasis für eine weiterführende Analyse auf quantitativer Ebene.

Explorative analysis of heterogeneous structures of retail nurseries
In a possible approach towards breaking up the heterogeneous structures of retail nurseries in view of the product range, situational influence quantities are systematically identified (contingency approach). Proceding in an explorative way, and aside from the organisational form and the size of holdings, a qualitative content analysis reveals significant individual variables within the service spectrum that consists of the number of mere service departments/independent service companies, the service experience and the kind of service. Once these parameters have been identified, they allow an initial classification into either retail- or service-oriented types of holdings and they provide a starting point for further analyses at a quantitative level.

Analyse explorative des structures hétérogènes d’organisation illustrées à partir de l’exemple du commerce de détail horticole
Afin d’illustrer les structures hétérogènes du commerce horticole en vue de la gamme des services offerts, l’identification systématiques des quantités situatives d’influence s’avère opportun. Un procédé exploratif a été choisi. Outre la forme d‘organisation et la taille d’une entreprise, une analyse de contenue qualitative révèle surtout des variables individuelles de la gamme de services composées du nombre de rayons de prestation de services/d’entreprises de service indépendantes, de l’expérience en matière de prestation de service et du type de service prêtè. Une fois ces facteurs indentifiés, ils permettent une première classification des entreprises selon leur orientation soit vers le commerce en détail soit vers la prestation de service ce qui constitue un point de départ pour une analyse approfondie au niveau quantitatif.

Simulating p-nuclei abundances in astrophysical environments
Creators: name: Wen, Alex Yuanming
Publisher: name: The University of British Columbia
Year: 2022

description: p-nuclei are a collection of neutron-deficient nuclei whose synthesis (to produce ob- served abundances) is relatively poorly understood. In this primarily computational work, we use NuGrid reaction networks to study two astrophysical sites, core-collapse supernovae and x-ray bursts, where p-nuclei are thought to be synthesized. We sim- ulate the production of p-nuclei at these two sites. We perform a Monte Carlo study by varying the reaction rates over many iterations of the reaction network and study- ing the corresponding p-nuclei abundance distributions. In doing so, we report on the characteristics of such abundance distributions and identify some key rates with uncertainties that are highly correlated to p-nuclei abundance uncertainties. This work is a starting point in informing experimental efforts to constrain abundance uncertainties.

description: The decades-long explorations on the dispersal of protoplanetary disks involve many debates about photoevaporation versus magnetized wind launching mechanisms. This letter argues that the observed winds originating from the inner disk ($R\lesssim 0.3$ AU) cannot be explained by the photoevaporative mechanism. Energy conservation requires the presumed photoevaporative winds to be heated to $\gtrsim 10^5$ K when launched from inner disks. However, due to efficient thermal accommodation with dust grains and cooling processes at high densities, X-ray irradiation at energies above 1 keV cannot efficiently launch winds in the first place because of its high penetration. Some studies claiming X-ray wind launching have oversimplified the thermochemical couplings. Furthermore, heating the gas to escape velocity will over-ionize it, suppressing the species responsible for observed forbidden lines (e.g., [OI] 6300 $Å$ ). Confirmed by semi-analytic integrations of thermochemical fluid structures, such high ionizations contradict the observed emission of neutral and singly-ionized atoms from the winds originating from the inner disks.

Stoudios Monastery also known as “Imrahor Ilyas Bey Mosque and Tekke”, “Church of Saint John the Baptist”, “Church of Hagios Ioannes Prodromos”
Creators: name: Schmidt, Tracey
Publisher: name: Database of Religious History (DRH)
Year: 2022

description: The Stoudios monastery was established in the early 5th century, and has been occupied for much of its existence since then. The church that remains is the oldest in Istanbul. This entry largely deals with the middle period of its history: from Sabas' and then Theodore's appointment as abbot in Byzantium's Iconoclastic period during the late 8th century; through to the Ottoman seizure of the city in 1453. It was occupied by different groups before and after who were no less interesting, but are less well documented. This was one of the most important and largest monasteries in the Byzantine capital of Constantinople from Theodore's appointment through to the 13th century Latin crusade. It was a crucial institution in its own right within the Christian Orthodox faith. Theodore of Stoudios was made the hegemonous or superior abbot over the akoimetoi monastery in the late 790s by Empress Eirene and the imperial court. Theodore's typikon, rule of monastic life, stressed the value and virtue in labour, literacy, and charitable activity. This template would be reused by some Greek monasteries and the bulk of Russian Orthodox monasteries up to today. The monastery enjoyed financial patronage, and at times imperial favour. The Stoudites would remain an independent voice in ecumenical voice in ecumenical and imperial politics. They worked towards self sufficiency across their wide estates and related monasteries outside the city, while the Constantinoplian estates were positioned along the triumphal or parade route for emperors returning to the city and their palaces further east along the peninsula. The monastery housed relics which drew visitors and pilgrims, notably of St John the Baptist, as well as leaving a lasting impression in Medieval Greek scribal traditions. What is visible today are the exterior walls and some of the floor mosaics of only the main church or kathlokion; and to some extent the cistern beneath. It is open to the elements, unoccupied, and unpreserved. The rest of the site is assumed from textual sources.

description: In general relativity, the motion of an extended test body is influenced by its proper rotation, or spin. We present a covariant and physically self-consistent Hamiltonian framework to study this motion, up to quadratic order in the body's spin, including a spin-induced quadrupole, and in an arbitrary background spacetime. The choice of spin supplementary condition and degeneracies associated with local Lorentz invariance are treated rigorously with adapted tools from Hamiltonian mechanics. Applying the formalism to a background space-time described by the Kerr metric, we prove that the motion of any test compact object around a rotating black hole defines an integrable Hamiltonian system to linear order in the body's spin. Moreover, this integrability still holds at quadratic order in spin when the compact object has the deformability expected for an isolated black hole. Our analytical results shed light on longstanding numerical conjectures regarding spin-induced chaos in the motion of asymmetric compact binaries, and provides a powerful framework to improve current gravitational waveform modelling to account for spin-induced extended body effects.

Reducing Impacts of System Heterogeneity in Federated Learning using Weight Update Magnitudes
Creators: name: Wang, Irene
Publisher: name: The University of British Columbia
Year: 2022

description: The widespread adoption of handheld devices have fueled rapid growth in new applications. Several of these new applications employ machine learning models to train on user data that is typically private and sensitive. Federated Learning enables machine learning models to train locally on each handheld device while only synchronizing their neuron updates with a server. While this enables user privacy, technology scaling and software advancements have resulted in handheld devices with varying performance capabilities. This results in the training time of federated learning tasks to be dictated by a few low-performance straggler devices, essentially becoming a bottleneck to the entire training process. In this work, we aim to mitigate the performance bottleneck of federated learning by dynamically forming sub-models for stragglers based on their performance and accuracy feedback. To this end, we offer the Invariant Dropout, a dynamic technique that forms a sub-model based on the neuron update threshold. Invariant Dropout uses neuron updates from the non-straggler clients to develop a tailored sub-models for each straggler during each training iteration. All corresponding weights which have a magnitude less than the threshold are dropped for the iteration. We evaluate Invariant Dropout using five real-world mobile clients. Our evaluations show that Invariant Dropout obtains a maximum accuracy gain of 1.4% points over state-of-the-art Ordered Dropout while mitigating performance bottlenecks of stragglers.

Boosting sustainable digitalisation in agriculture, forestry and rural areas by 2040. Webinar highlights
Creators: name: Garrido, Lucía

description: On 30 June 2021, the DESIRA Rural Digitalisation Forum (RDF) held a webinar to discuss the role of digitalisation in the European Commission’s long-term vision for rural areas (LTVRA), and the policy support needed to ensure that digitalisation leads to sustainable development of rural areas.
 With this EU initiative­ - ­developed through a participatory process with rural actors which included a public consultation, stakeholder-led events and an ENRD conference among others - the European Commission launches a holistic vision that proposes a new Rural Pact and a Rural Action Plan with a number of flagship initiatives to help rural communities and businesses reach their full potential by 2040.
 DESIRA contributed to this process by capitalising on the knowledge produced so far in the project and gathering the views of experts of the DESIRA RDF on how digital technologies can contribute to building desirable futures for rural areas by 2040 (See more information here). The RDF also proposes seven guiding principles that need to be applied in order to boost sustainable digitalisation in agriculture, forestry and rural areas.

description: Uranium ditelluride (UTe$_2$) is recognized as a host material to unconventional spin-triplet superconductivity, but it also exhibits a wealth of additional unusual behavior at high magnetic fields. One of the most prominent signatures of the unconventional superconductivity is a large and anisotropic upper critical field that exceeds the paramagnetic limit. This superconductivity survives to 35 T and is bounded by a discontinuous magnetic transition, which itself is also field-direction-dependent. A different, reentrant superconducting phase emerges only on the high-field side of the magnetic transition, in a range of angles between the crystallographic $b$ and $c$ axes. This review discusses the current state of knowledge of these high-field phases, the high-field behavior of the heavy fermion normal state, and other phases that are stabilized by applied pressure.

description: Noise in quantum devices is generally considered detrimental to computational accuracy. However, the recent proposal of noise-assisted simulation has demonstrated that noise can be an asset in digital quantum simulations of open systems on Noisy Intermediate-Scale Quantum (NISQ) devices. In this context, we introduce an optimized decoherence rate control scheme that can significantly reduce computational requirements by multiple orders of magnitude, in comparison to the original noise-assisted simulation. We further extend this approach to encompass Lindblad equations with time-dependent coefficients, using only quantum error characterization and mitigation techniques. This extension allows for the perturbative simulation of non-Markovian dynamics on NISQ devices, eliminating the need for ancilla qubits or mid-circuit measurements. Our contributions are validated through numerical experiments on an emulated IBMQ device. Overall, our work offers valuable optimizations that bring current quantum processors closer to effectively simulating realistic open systems.

description: That light propagating in a gravitational field gets frequency-shifted is one of the basic consequences of any metric theory of gravity rooted in the equivalence principle. At the same time, also a time dependent material's refractive index can frequency-shift light propagating in it. The mathematical analogy between the two effects is such that the latter has been used to study the optical analogue of a black-hole spacetime. Here, we combine these two effects by showing that light propagation in non-linear media in the presence of a moving refractive index perturbation can lead to a gravity-dependent blueshift. We find that the predicted blueshift surpasses the gravitational redshift even if the medium is considered to be perfectly stiff. In realistic scenarios, by far the strongest frequency shift arises due to the deformation of the dielectric medium and the corresponding photoelastic change of refractive index. This has the potential to facilitate optical sensing of small gravity gradients.

BioExcel Webinar #65: QM/MM Simulation of Fluorescent Proteins and Proton Dynamics

Subjects: webinar

description: This webinar presents two examples of research done within BioExcel that demonstrates how hybrid quantum/classical (QM/MM) simulations using GROMACS, CP2K and CPMD performed on high-performance computing (HPC) resources can be used to elucidate biomolecular properties and mechanisms not accessible through a purely classical description. As well as giving insight into particular systems of interest – fluorescent proteins and proton dynamics in bioanalytical mass spectrometry – the webinar serves as an illustration of how the QM/MM approach generally and the above software in particular can be used productively to tackle biomolecular problems.

 Fluorescent proteins are the backbone for high-resolution biological imaging, but designing suitable proteins for specific experimental conditions is difficult. The goal of our work in BioExcel is to unlock the predictive power of MD and QM/MM simulations for predicting and optimizing the properties of such systems. We have thus developed a protocol to automatically compute the relevant quantities of these proteins and their mutants based on established atomistic simulation methods. The protocol combines (i) force field MD simulations with GROMACS, (ii) PMX and free-energy calculations, and (iii) QM/MM calculations to predict the thermostability (protein folding and oligomerization affinity) and photochemical properties (absorption spectrum and emission spectrum) of fluorescent proteins. Mass spectrometry has become a powerful tool in bioanalytics and can predict structural data of biomolecules at low resolution. Indeed, mass spectrometry requires far less samples than any other higher solution structural biology technique. However, the interpretation of the data is non-trivial. Beside structural changes upon passage from solution into the gas phase, one of the main difficulties in interpreting the data is the presence of quantum phenomena associated with proton transfer. Atomistic simulation gives invaluable insights on these processes. Here, we studied such phenomena by the application of high-performance computing QM/MM software developed within BioExcel to provide important information for the interpretation of mass spectrometry data.

description: Background: Obstructive sleep apnea (OSA) is a common disorder that is highly associated with postoperative complications. The STOP-Bang questionnaire is a simple screening tool for OSA. The objective of this systematic review and meta-analysis is to evaluate the validity of the STOP-Bang questionnaire for screening OSA in the surgical population cohort. Methods: A systematic search of the following databases was performed from 2008 to May 2021: MEDLINE, Medline-in-process, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, Journals @ Ovid, Web of Science, Scopus, and CINAHL. Continued literature surveillance was performed through October 2021. Results: The systematic search identified 4641 articles, from which 10 studies with 3247 surgical participants were included in the final analysis. The mean age was 57.3 ± 15.2 years, and the mean BMI was 32.5 ± 10.1 kg/m2 with 47.4% male. The prevalence of all, moderate-to-severe, and severe OSA were 65.2, 37.7, and 17.0%, respectively. The pooled sensitivity of the STOP-Bang questionnaire for all, moderate-to-severe, and severe OSA was 85, 88, and 90%, and the pooled specificities were 47, 29, and 27%, respectively. The area under the curve for all, moderate-to-severe, and severe OSA was 0.84, 0.67, and 0.63. Conclusions: In the preoperative setting, the STOP-Bang questionnaire is a valid screening tool to detect OSA in patients undergoing surgery, with a high sensitivity and a high discriminative power to reasonably exclude severe OSA with a negative predictive value of 93.2%.

description: We present a thorough experimental investigation on single crystals of the rare-earth based frustrated quantum antiferromagnet Pr$_3$BWO$_9$, a purported spin-liquid candidate on the breathing kagome lattice. This material possesses a disordered ground state with an unusual excitation spectrum involving a coexistence of sharp spin-waves and broad continuum excitations. Nevertheless, we show through a combination of thermodynamic, magnetometric and spectroscopic probes with detailed theoretical modeling that it should be understood in a completely different framework. The crystal field splits the lowest quasi-doublet states into two singlets moderately coupled through frustrated superexchange, resulting in a simple effective Hamiltonian of an Ising model in a transverse magnetic field. While our neutron spectroscopy data do point to significant correlations within the kagome planes, the dominant interactions are out-of-plane, forming frustrated triangular spin-tubes through two competing ferro-antiferromagnetic bonds. The resulting ground state is a simple quantum paramagnet, but with significant modifications to both thermodynamic and dynamic properties due to small perturbations to the transverse field Ising model in the form of hyperfine enhanced nuclear moments and weak structural disorder.

description: Mechanisms are essential components designed to perform specific tasks in various mechanical systems. However, designing a mechanism that satisfies certain kinematic or quasi-static requirements is a challenging task. The kinematic requirements may include the workspace of a mechanism, while the quasi-static requirements of a mechanism may include its torque transmission, which refers to the ability of the mechanism to transfer power and torque effectively. In this paper, we propose a deep learning-based generative model for generating multiple crank-rocker four-bar linkage mechanisms that satisfy both the kinematic and quasi-static requirements aforementioned. The proposed model is based on a conditional generative adversarial network (cGAN) with modifications for mechanism synthesis, which is trained to learn the relationship between the requirements of a mechanism with respect to linkage lengths. The results demonstrate that the proposed model successfully generates multiple distinct mechanisms that satisfy specific kinematic and quasi-static requirements. To evaluate the novelty of our approach, we provide a comparison of the samples synthesized by the proposed cGAN, traditional cVAE and NSGA-II. Our approach has several advantages over traditional design methods. It enables designers to efficiently generate multiple diverse and feasible design candidates while exploring a large design space. Also, the proposed model considers both the kinematic and quasi-static requirements, which can lead to more efficient and effective mechanisms for real-world use, making it a promising tool for linkage mechanism design.

description: Multimode squeezed light is an increasingly popular tool in photonic quantum technologies, including sensing, imaging, and computation. Meanwhile, the existing methods of its characterization are technically complicated, and in the best case, deal with a single mode at a time. Here, we demonstrate experimentally how the squeezing can be measured in multiple spatial modes simultaneously, using optical parametric amplification and direct detection followed by modal decomposition based on spatial intensity correlations. We apply this method to a multimode squeezed vacuum generated via high-gain parametric down-conversion. We measure the degrees of squeezing and anti-squeezing for eight strongest spatial modes, obtaining highest squeezing and anti-squeezing values of $-5.2 \pm 0.2$ dB and $8.6 \pm 0.3$ dB, respectively.
