Long-term effects of peer and teacher feedback on L2 pronunciation
Authors: Martin Ines A. , Sippel Lieselotte 
Published: February 2023

AbstractThis study investigated the long-term effects of peer and teacher feedback on pronunciation development. Participants included 94 learners of German. They were assigned to a teacher feedback group (TeacherF Group), a peer feedback provider group (PeerF Providers), a peer feedback receiver group (PeerF Receivers), or a control group. After completing general pronunciation training on a segmental and a suprasegmental feature in German, the TeacherF Group received feedback on their pronunciation from a teacher, the PeerF Providers gave feedback to peers, and the PeerF Receivers received feedback from peers. The control group did not complete pronunciation training or receive feedback. Results from native speaker comprehensibility ratings of learners’ productions indicated that while the TeacherF Group and the PeerF Receivers improved in the short term, only the PeerF Providers maintained their gains in pronunciation development over time. Methodological and pedagogical implications of these findings are discussed.

Résumé
Les œuvres d’Édouard Levé sont encadrées par un dispositif de lecture qui nous permet de les situer en rapport avec la biographie de l’auteur, de dégager les principaux traits de sa poétique, de formuler des hypothèses génétiques. Ses travaux se révèlent ainsi d’une grande cohérence, comme autant de variations sur une série de gestes et de questionnements à la fois très simples et très radicaux.
En s’inspirant largement du Procédé de Raymond Roussel Levé a fondé une partie de son œuvre sur une poétique des décalages consistant à brouiller les rapports des mots aux images. Cette poétique est mise en œuvre dans trois séries Homonymes, Angoisse et Amérique, produites par une même contrainte linguistique et des protocoles de réalisation semblables, mais chacune répond à des attitudes et des effets différents de ces contraintes et de ces protocoles. Il s’agit dans Angoisse de créer une fiction, dans Homonymes d’interroger le panthéon culturel et dans Amérique d’offrir un négatif de l’american dream.
The analysis of the far-field phase and the tilt-to-length error contribution in space-based laser interferometry

Published: February 2023

Abstract
The arm length of the space-based interferometer for gravitational wave detection is 108–109

m

, and picometer precision is required. The wavefront error in the far-field coupled with the pointing jitter is a major noise source, which raises higher requirements of the wavefront quality of the telescope. By extending the analytical solutions of the far-field phase to 21 Zernike aberrations, this paper demonstrates that the far-field phase could be regarded as the sum of the effects of the individual aberrations and a phase plane with its slope related to the wavefront RMS. For individual aberrations, only low-order aberrations have a significant effect on the far-field phase, but high-order aberrations will contribute to the coupling terms which is shown as a phase slope. So there is a definite corresponding relationship between the aberrations and the far-field phase, and it can be easily illustrated graphically. Based on the analytical solutions of the far-field phase, we proposed to consider the tilt-to-length (TTL) error together with the far-field phase. The TTL error is also one of the main noise sources in space-based laser interferometry, which presents big difficulties in the optical system. We found that TTL error could be added to the far-field phase as a piston term during pointing, which then help to bring the stationary point closer to the z-axis and reduce the phase noise detected at the stationary point. By considering the TTL together with the far-field phase, the requirement of the telescope could be λ/25 wavefront RMS (λ = 1064

nm

). And there will be a large tolerance range for the TTL error, so it is only necessary to evaluate the TTL error and limit it to a suitable range, not to eliminate it.
Shape resonances in angle-resolved photoionization of aligned CF3I molecules
Authors: Brausse Felix , Vrakking Marc J J , Rouzée Arnaud 
Published: February 2023

Abstract
The photoionization of CF3I molecules in the photon energy range between 10 eV and 40 eV is investigated using angle-resolved photoelectron spectroscopy in the molecular frame. Using a femtosecond laser pulse, the molecules are impulsively aligned prior to their ionization by a series of extreme ultra-violet photon energies obtained by high-harmonic generation. The manifestation of molecular alignment in the photoelectron angular distributions (PADs) is well reproduced by non-relativistic quantum-mechanical photoionization calculations carried out with the ePolyScat software package, taking into account all open ionization channels. Our analysis points to two prominent shape resonances that dominate the photoelectron scattering dynamics and that therefore largely explain the observed changes in the PADs as a function of molecular alignment.
A speakerless acoustic thermometer

Published: February 2023

Abstract
Existing acoustic thermometers are often implemented using speaker-microphone systems, which are power-consuming and inconvenient to operate. Here we demonstrate a simple speakerless acoustic thermometer, which is an acoustic Fabry–Perot resonator (AFPR) consisting of a tubular acoustic waveguide and a microphone whose diaphragm acts as a reflective surface of the AFPR. Theoretical analysis shows that the resonant frequency (RF) ( fm
) at a given mode order (m) for the AFPR is a linear function of m with the slope (Δf/Δm) depending on the ambient temperature. Therefore, when the linear relationship between fm
and m for the AFPR is measured, the ambient temperature can be determined from its slope. The values of fm
at different m can be easily obtained by using the AFPR to detect ambient white noise rather than the sound signal from a loudspeaker. The thermometric performance of the prepared AFPR was investigated in a range of temperatures from −17 °C to 60 °C. The measured temperatures show the mean absolute error below 0.9 °C relative to those simultaneously obtained with a commercial electronic thermometer. As experimentally demonstrated in this work, the AFPR can detect extremely weak white noise in the anechoic room and thus enables to accurate measure the ambient temperature there, attributable to its ultrahigh pressure sensitivity at each RF. The advantages of simple structure, low power consumption, convenient operation, and high detection accuracy offer the AFPR outstanding applicability for on-site temperature measurements in various environments.
Mapping atomic trapping in an optical superlattice onto the libration of a planar rotor in electric fields
Authors: Mirahmadi Marjan , Friedrich Bretislav , Schmidt Burkhard , Pérez-Ríos Jesús 
Published: February 2023

Abstract
We show that two seemingly unrelated problems—the trapping of an atom in an optical superlattice (OSL) and the libration of a planar rigid rotor in combined electric and optical fields (PR) – have isomorphic Hamiltonians. Formed by the interference of optical lattices whose spatial periods differ by a factor of two, OSL gives rise to a periodic potential that acts on atomic translation via the AC Stark effect. The PR system, also known as the generalized planar pendulum, is realized by subjecting a planar rigid rotor to combined orienting and aligning interactions due to the coupling of the rotor’s permanent and induced electric dipole moments to the combined fields. The PR system belongs to the class of conditionally quasi-exactly solvable problems and exhibits intriguing spectral properties that have been established in our previous work Becker et al (2017 Eur. Phys. J. D
71 149). Herein, we make use of both the PR

↦

OSL mapping and the quasi-exact solvability of the PR system to treat ultracold atoms in an OSL as a semifinite-gap system. The band structure of this system follows from the eigenenergies and their genuine and avoided crossings obtained previously for the PR system as solutions of the Whittaker-Hill equation. These solutions characterize both the squeezing and the tunneling of atoms trapped in an OSL and pave the way to unraveling their dynamics in analytic form. Furthermore, the PR

↦

OSL mapping makes it possible to establish correspondence between concepts developed for the two eigenproblems individually, such as localization on the one hand and orientation/alignment on the other.
Reverse-time type nonlocal Sasa–Satsuma equation and its soliton solutions
Authors: Yan Xue-Wei , Chen Yong 
Published: February 2023

Abstract
In this work, we study the Riemann–Hilbert problem and the soliton solutions for a nonlocal Sasa–Satsuma equation with reverse-time type, which is deduced from a reduction of the coupled Sasa–Satsuma system. Since the coupled Sasa–Satsuma system can describe the dynamic behaviors of two ultrashort pulse envelopes in birefringent fiber, our equation presented here has great physical applications. The classification of soliton solutions is studied in this nonlocal model by considering an inverse scattering transform to the Riemann–Hilbert problem. Simultaneously, we find that the symmetry relations of discrete data in the special nonlocal model are very complicated. Especially, the eigenvectors in the scattering data are determined by the number and location of eigenvalues. Furthermore, multi-soliton solutions are not a simple nonlinear superposition of multiple single-solitons. They exhibit some novel dynamics of solitons, including meandering and sudden position shifts. Also, they have the bound state of multi-soliton entanglement and its interaction with solitons.

Abstract
The microwave plasma diagnosis in-situ irradiation system
has been developed at the Central University of Punjab,
Bathinda. The final design is achieved by a combination of
analytical and simulation methods using CST and Comsol Multiphysics
software. Simulations outcome reveals the electric field profile at
the center of the microwave plasma chamber is strong and dense. A
strong electric field profile inside the microwave cavity has been
verified by the confinement of the plasma in the absence of an
external magnetic field. The magnetic field profile for the
2450 MHz microwave facility is simulated and confirmed
experimentally. Different RF powers and working gas pressures have
been used with Langmuir probes to record the plasma signal. As a
second stage, we studied the practicality of using a plasma cavity
to treat materials with plasma for materials science experiment in
plasma environment. This work shows the results of a thorough
computational analysis of a microwave plasma source that has been
tested in lab.
Thermodynamic speed limits for mechanical work
Authors: Aghion Erez , Green Jason R 
Published: February 2023

Abstract
Thermodynamic speed limits are a set of classical uncertainty relations that, so far, place global bounds on the stochastic dissipation of energy as heat and the production of entropy. Here, instead of constraints on these thermodynamic costs, we derive integral speed limits that are upper and lower bounds on a thermodynamic benefit—the minimum time for an amount of mechanical work to be done on or by a system. In the short time limit, we show how this extrinsic timescale relates to an intrinsic timescale for work, recovering the intrinsic timescales in differential speed limits from these integral speed limits and turning the first law of stochastic thermodynamics into a first law of speeds. As physical examples, we consider the work done by a flashing Brownian ratchet and the work done on a particle in a potential well subject to external driving.

In this work we will use a general procedure to construct higher local Hamiltonians for the affine

Gaudin model. We focus on the first non-trivial example, the quartic Hamiltonians. We show by direct calculation that the quartic Hamiltonians commute amongst themselves and with the quadratic Hamiltonians which define the model. We go on to introduce a certain next-to-leading-order semi-classical limit of the model. In this limit, we are able to write down the full hierarchy of higher local Hamiltonians and prove that they commute.

Abstract
Craniofacial bone regeneration is a coupled process of angiogenesis and osteogenesis, which, associated with infection, still remains a challenge in bone defects after trauma or tumor resection. 3D tissue engineering scaffolds with multifunctional-therapeutic properties can offer many advantages for the angiogenesis and osteogenesis of infected bone defects. Hence, in the present study, a microchannel networks-enriched 3D hybrid scaffold composed of decellularized extracellular matrix (dECM), gelatin (Gel), quaterinized chitosan (QCS) and nano-hydroxyapatite (nHAp) (dGQH) was fabricated by an extrusion 3D bioprinting technology. And enlightened by the characteristics of natural bone microstructure and the demands of vascularized bone regeneration, the exosomes (Exos) isolated from human adipose derived stem cells as angiogenic and osteogenic factors were then co-loaded into the desired dGQH20 hybrid scaffold based on an electrostatic interaction. The results of the hybrid scaffolds performance characterization showed that these hybrid scaffolds exhibited an interconnected pore structure and appropriate degradability (>61% after 8 weeks of treatment), and the dGQH20 hybrid scaffold displayed the highest porosity (83.93 ± 7.38%) and mechanical properties (tensile modulus: 62.68 ± 10.29 MPa, compressive modulus: 16.22 ± 3.61 MPa) among the dGQH hybrid scaffolds. Moreover, the dGQH20 hybrid scaffold presented good antibacterial activities (against 94.90 ± 2.44% of Escherichia coli and 95.41 ± 2.65% of Staphylococcus aureus, respectively) as well as excellent hemocompatibility and biocompatibility. Furthermore, the results of applying the Exos to the dGQH20 hybrid scaffold showed that the Exo promoted the cell attachment and proliferation on the scaffold, and also showed a significant increase in osteogenesis and vascularity regeneration in the dGQH@Exo scaffolds in vitro and in vivo. Overall, this novel dECM/Gel/QCS/nHAp hybrid scaffold laden with Exo has a considerable potential application in reservation of craniofacial bone defects.
An update of the pharmacological treatment options for generalized myasthenia gravis in adults with anti–acetylcholine receptor antibodies
Authors: Riley Tanya R , Douglas Janine S , Wang Christopher , Bowser Kiarra M 
Published: February 2023

AbstractPurposeThis review aims to provide an update on current pharmacological agents for the management of generalized myasthenia gravis (MG).SummaryMG is an autoimmune disease characterized by impaired neuromuscular transmission and muscle weakness. Most patients have autoimmune antibodies to the nicotinic acetylcholine receptor, with treatments aimed at eliminating or decreasing levels of autoantibodies. Limitations of current treatments for generalized MG include limited efficacy and serious adverse effects, indicating a continued need for new treatments. Efgartigimod alfa, a biologic newly approved by the Food and Drug Administration, provides a novel treatment option for patients with chronic generalized MG.ConclusionWhile the landscape for treatment of generalized MG has expanded over recent years, there is still an unmet need for patients for whom multiple lines of treatment have failed. The introduction of neonatal Fc receptor antagonists such as efgartigimod alfa may have an immediate impact in patients for whom standard-of-care therapy has failed.
A hybrid positive unlabeled learning framework for uncovering scaffolds across human proteome by measuring the propensity to drive phase separation
Authors: Jiang Peiran , Cai Ruoxi , Lugo-Martinez Jose , Guo Yaping 
Published: February 2023

AbstractScaffold proteins drive liquid–liquid phase separation (LLPS) to form biomolecular condensates and organize various biochemical reactions in cells. Dysregulation of scaffolds can lead to aberrant condensate assembly and various complex diseases. However, bioinformatics predictors dedicated to scaffolds are still lacking and their development suffers from an extreme imbalance between limited experimentally identified scaffolds and unlabeled candidates. Here, using the joint distribution of hybrid multimodal features, we implemented a positive unlabeled (PU) learning-based framework named PULPS that combined ProbTagging and penalty logistic regression (PLR) to profile the propensity of scaffolds. PULPS achieved the best AUC of 0.8353 and showed an area under the lift curve (AUL) of 0.8339 as an estimation of true performance. Upon reviewing recent experimentally verified scaffolds, we performed a partial recovery with 2.85% increase in AUL from 0.8339 to 0.8577. In comparison, PULPS showed a 45.7% improvement in AUL compared with PLR, whereas 8.2% superiority over other existing tools. Our study first proved that PU learning is more suitable for scaffold prediction and demonstrated the widespread existence of phase separation states. This profile also uncovered potential scaffolds that co-drive LLPS in the human proteome and generated candidates for further experiments.

Authors: Wu Yuemeng , Gu Chaoying , Wang Shangshang , Yin Huibin , Qiu Zhuoqiong , Luo Yang , Li Zheng , Wang Ce , Yao Xu , Li Wei 
Published: February 2023

Abstract

Background
Atopic dermatitis (AD) is a highly heterogeneous disease clinically and biologically. Serum biomarkers have been utilized for endotype identification and have the potential to be predictors for treatment.

Objectives
To explore the serum biomarker-based endotypes of Chinese patients with AD and to identify biomarkers for prediction of the efficacy of dupilumab.

Methods
Sera from 125 patients with moderate-to-severe AD and 60 normal controls (NC) were analysed for 24 cytokines/chemokines using the magnetic Luminex assay. After the patients received 16 weeks of dupilumab treatment, the efficacy was evaluated, and blood eosinophils, serum immunoglobulin (Ig) E and biomarkers were measured.

Results
Chinese patients with moderate-to-severe AD were characterized by T-helper (Th)2-dominant serum biomarkers that were mixed with differentially increased Th1-, Th17- and Th22-type cytokines/chemokines, and it was mainly Th2-type serum biomarkers that were positively correlated with disease severity and eosinophil counts. Adult (but not adolescent or elderly) patients with AD showed a consistent and more significant increase of biomarkers across different types of inflammation. The patients were grouped into two clusters by unsupervised k-means analysis, which were differentially associated with inflammation. Treatment with dupilumab decreased the levels of most cytokines/chemokines analysed. While there was no difference between the two clusters in the efficacy of dupilumab, baseline levels of CD25/soluble interleukin (sIL)-2Rα, IL-31 and IL-36β were identified as predictive factors associated with the efficacy.

Conclusions
Our study revealed two inflammation-related endotypes of Chinese patients with AD based on serum biomarkers. High levels of CD25/sIL-2Rα, IL-31 and IL-36β might predict good efficacy of dupilumab treatment.

Abstract

Background
The Lémann Index [LI] and the recently updated LI are tools for measuring structural bowel damage in adults with Crohn’s disease [CD] but have not been evaluated in children. We aimed to validate the updated LI in the prospective multicentre ImageKids study of paediatric CD.

Methods
We included children with CD undergoing magnetic resonance enterography [MRE], pelvic magnetic resonance imaging [MRI] and ileocolonoscopy. Half were followed for 18 months, when MRE was repeated. Serum was collected for fibrosis-related proteomic markers. The LI was calculated by central readers from the MRE, ileocolonoscopy, physical examination and surgical data. Reliability and construct validity were assessed at baseline, while responsiveness and test–retest reliability were explored longitudinally.

Results
In total, 240 children were included (mean age, 14.2 ± 2.5 years; median disease duration, 2.2 years [interquartile range, IQR 0.25–4.42]; median baseline LI, 4.23 [IQR 2.0–8.8]). The updated LI had excellent inter-observer reliability (interclass correlation coefficient [ICC] = 0.94, 95% confidence interval [CI] 0.92–0.95) but poor, although statistically significant, correlation with radiologist and gastroenterologist global assessments of damage and with serum proteomic levels of fibrotic markers [rho = 0.15–0.30, most p &lt; 0.05]. The updated LI had low discriminative validity for detecting damage (area under the receiver operating characteristic curve [AUC-ROC] 0.69, 95% CI 0.62–0.75). In 116 repeated MREs, responsiveness was suboptimal for differentiating improved from unchanged disease [AUC-ROC 0.58, 95% CI 0.45–0.71]. Test–retest reliability was high among stable patients [ICC = 0.84, 95% CI 0.72–0.91].

Conclusion
Overall, the updated LI had insufficient psychometric performance for recommending its use in children. An age-specific index may be needed for children with shorter disease duration than typical adult cohorts.
