Teletherapy and Multi-Tiered System of Support: Synergies and Challenges for School-Based Speech-Language Pathologists
Authors: Sylvan Lesley , Gouck Madeleine , Kwak Madelyn 
Published: February 2025

Purpose:
This exploratory study examines the intersection of teletherapy and multi-tiered system of support (MTSS) in school-based speech-language services and explores ways in which the challenges related to MTSS vary by service delivery modality.

Method:
This study involved 10 interviews with five speech-language pathologists (SLPs) who have had experience in both in-person and teletherapy-based positions and were working for the same educational agency as teletherapists during the 2023–2024 school year. Qualitative data were collected about unique facilitators and barriers teletherapists face concerning MTSS and how the defining features of teletherapy (e.g., technology and on-site facilitation with a remote SLP) impact their engagement with MTSS in both helpful and constraining ways.

Results:
Participants, all of whom worked remotely with students attending schools in person, identified a number of opportunities and challenges related to engagement with MTSS. Some challenges were identified as common to both face-to-face and remote work (e.g., misunderstandings related to the role of SLPs in MTSS). Others were unique to teletherapy in ways that made implementation easier (e.g., intentionally planned and focused conversations) as well as harder (e.g., lack of visibility and spontaneity). There were pros and cons of how technology and on-site facilitation impacted MTSS implementation.

Conclusion:
As teletherapy and prevention-oriented work gain prominence in the postpandemic reality, this study offers initial insights into the synergies and challenges of engaging with the MTSS as a school-based teletherapist.

Published: February 2025

Purpose:
This study aims to examine caregiver perceptions and use of the Early Communication Indicator–Autism (ECI-A), an adapted, naturalistic assessment to measure progress on communication skills, and explore differences across racial and ethnic groups to provide preliminary data about the cultural responsiveness of the newly adapted ECI-A.

Method:
A total of 215 caregivers and their autistic child completed the ECI-A. The research team collected data on caregiver- and researcher-reported ease of use of the ECI-A and caregiver ECI-A fidelity. Descriptive statistics are reported across racial and ethnic groups, and group differences are examined between groups with sufficient sample size (Black and White caregivers, Latino and non-Latino caregivers).

Results:
Overall, there was consistency in caregiver and researcher perceptions of ease of use and caregiver fidelity. The only statistically significant differences were for researcher-reported ease of use between Black and White caregivers and ECI-A fidelity for general procedures between Latino and non-Latino caregivers.

Conclusions:
The results suggest that the ECI-A is acceptable and feasible for use by caregivers from a range of racial and ethnic backgrounds. However, the two statistically significant differences suggest the need for careful attention to researcher biases for researcher-completed measures and more in-depth evaluation of the cultural responsiveness of the general ECI-A procedures, such as the number of play partners involved. It will be critical to continue work that informs and advances the use of culturally responsive assessment practices with autistic children and their families in the future.

Context. K-dwarf stars are promising targets in the exploration of potentially habitable planets. Their properties, falling between G and M dwarfs, provide an optimal trade-off between the prospect of habitability and ease of detection. The KOBE experiment is a blind-search survey exploiting this niche, monitoring the radial velocity of 50 late-type K-dwarf stars. It employs the CARMENES spectrograph, with an observational strategy designed to detect planets in the habitable zone of their system.
Aims. In this work, we exploit the KOBE data set to characterize planetary signals in the K7 V star HIP 5957 (KOBE-1) and to constrain the planetary population within its habitable zone.
Methods. We used 82 CARMENES spectra over a time span of three years. We employed a generalized Lomb–Scargle periodogram to search for significant periodic signals that would be compatible with Keplerian motion on KOBE-1. We carried out a model comparison within a Bayesian framework to ensure the significance of the planetary model over alternative configurations of lower complexity. We also inspected two available TESS sectors in search of planetary signals.
Results. We identified two signals: at Pb = 8.5 d and Pc = 29.7 d. We confirmed their planetary nature through ruling out other non-planetary configurations. Their minimum masses are 8.80 ± 0.76 M⊕ (KOBE-1 b), and 12.4 ± 1.1 M⊕ (KOBE-1 c), corresponding to absolute masses within the planetary regime at a high certainty (>99.7%). By analyzing the sensitivity of the CARMENES time series to additional signals, we discarded planets above 8.5 M⊕ within the habitable zone. We identified a single transit-like feature in TESS, whose origin is still uncertain, but still compatible within 1σ with a transit from planet c.
Conclusions. The KOBE-1 multi-planetary system, consisting of a relatively quiet K7-dwarf hosting two sub-Neptune-minimum- mass planets, establishes the first discovery from the KOBE experiment. We have explored future prospects for characterizing this system, concluding that Gaia DR4 will be insensitive to their astrometric signature. Meanwhile, nulling interferometry with the Large Interferometer For Exoplanets (LIFE) mission could be capable of directly imaging both planets and characterizing their atmospheres in future studies.

AbstractWith resurgence in immediate tooth replacement therapy (ITRT) as a method of preserving both hard and soft tissues for improved aesthetic outcomes, this multicenter, prospective study looked at two novel products and their effect on those outcomes. Thirty-one maxillary single-tooth implants were included, of these 54.8% were central incisors, 25.8% lateral incisors, and 19.4% canines. Three complications were reported; one case nondraining fistula, one case a nonseated provisional restoration, and one case a fractured zirconia abutment. The definitive restorations were delivered between 4 hours and 18 months postimplant placement and all restorations were screw-retained. ITRT is frequently utilized when a tooth to be extracted will be replaced by an implant aiding in preservation of the hard and soft tissue that may be lost due to resorption during healing of the extraction socket. The narrower neck region of the Inverta implant results in thicker crestal bone around the implant, where loading under function occurs. Grafting that area around the implant at placement with EthOss results in more predictable bone stability in the long term.

Published: February 2025

Curved surface CMOS image sensors (CISs) mimic the structure of the human eye’s retina, reducing optical distortion and simplifying lens design. Compared to planar sensors, the curved design introduces additional stress during the molding process and increasing working temperature, affecting the photoelectric performance and geometric shape, thereby impacting image quality. This study established a force-heat simulation model to analyze various parameters affecting the stress of curved CIS chips. Furthermore, a theoretical model for thin-film stress was established using the Stoney formula to validate the accuracy of the simulation. In the experimental phase, a pneumatic pressure three-dimensional forming technique was employed to integrate ultra-thin CIS chips onto a concave spherical substrate. The three-dimensional morphology and photoelectric performance parameters of curved and planar CIS chips were measured under high-temperature ambient conditions. The results showed that the curved CIS chips integrated on a silicon concave spherical base exhibited a three-dimensional morphology change of less than 2 µm at high temperatures (∼85 °C). Regarding photoelectric performance, the dark current of the curved CIS devices decreased by about 2DN at high temperatures. In addition, the dynamic range decreased by about 17 dB, the signal-to-noise ratio decreased by about 16.5 dB, and the read noise increased by 0.3DN, with trends and values consistent with planar devices. The above-mentioned study indicates that curved CIS devices fabricated on a silicon base can maintain their three-dimensional morphology and photoelectric performance without significant degradation under high-temperature working conditions and can operate normally.
Measure schematicity through information content
Authors: Zhang Liulin , Tao Jiajun 
Published: February 2025

Abstract
Apropos of the level of specificity, schematicity is the key indicator of grammaticalization in linguistics;
compared to lexical items, the information provided by grammar patterns tends to be more abstract. With recourse to the notion of
the quantifiable information content in information theory, the schematicity of a schema can be quantified by comparing the
information content provided by the elements occurring in the open slots to that provided by the schema itself. A formula is
thereby proposed to measure schematicity. This schematicity measure is able to illustrate the gradience and gradualness of
grammaticalization in its applications in synchronic English data and diachronic Chinese data. Compared to previous measures of
grammaticalization, there is a notable improvement in reliability and applicability.
Commenting behavior as a mirror of parasocial relationships and emotional attachment on YouTube
Authors: Pelttari Sanna 
Published: February 2025

Abstract
Research on Influencer Marketing has flourished in recent years and has also encompassed the audience’s
perspective. Nevertheless, there is a lack of studies that specifically focus on the reception of IM as revealed by the YouTube
comments. This study examines comments on 12 product-promoting videos of Spanish YouTubers. The purpose is to provide insight into
the communicative behavior exhibited by social media users in comment sections and to reveal what these communicative acts reveal
of the bond between content creators and their followers in terms of parasocial relationship and emotional attachment. These two
phenomena are observed in the light of involvement strategies. The analysis emphasizes the high diversity of comment contents,
communicative acts and involvement practices involved. Results shed light on the diverse means that users employ to establish and
strengthen parasocial relationships on YouTube. The praising comments appear to symbolize an emotional attachment that bears
importance for the users.

Abstract

Objective. This study investigates the effects of various training protocols on enhancing the precision of MRI-only Pseudo-CT generation for radiation treatment planning and adaptation in head & neck cancer patients. It specifically tackles the challenge of differentiating bone from air, a limitation that frequently results in substantial deviations in the representation of bony structures on Pseudo-CT images. Approach. The study included 25 patients, utilizing pre-treatment MRI-CT image pairs. Five cases were randomly selected for testing, with the remaining 20 used for model training and validation. A 3D U-Net deep learning model was employed, trained on patches of size 643 with an overlap of 323. MRI scans were acquired using the Dixon gradient echo (GRE) technique, and various contrasts were explored to improve Pseudo-CT accuracy, including in-phase, water-only, and combined water-only and fat-only images. Additionally, bone extraction from the fat-only image was integrated as an additional channel to better capture bone structures on Pseudo-CTs. The evaluation involved both image quality and dosimetric metrics. Main results. The generated Pseudo-CTs were compared with their corresponding registered target CTs. The mean absolute error (MAE) and peak signal-to-noise ratio (PSNR) for the base model using combined water-only and fat-only images were 19.20 ± 5.30 HU and 57.24 ± 1.44 dB, respectively. Following the integration of an additional channel using a CT-guided bone segmentation, the model’s performance improved, achieving MAE and PSNR of 18.32 ± 5.51 HU and 57.82 ± 1.31 dB, respectively. The measured results are statistically significant, with a p-value

<

0.05. The dosimetric assessment confirmed that radiation treatment planning on Pseudo-CT achieved accuracy comparable to conventional CT. Significance. This study demonstrates improved accuracy in bone representation on Pseudo-CTs achieved through a combination of water-only, fat-only and extracted bone images; thus, enhancing feasibility of MRI-based simulation for radiation treatment planning.
Investigation of the Langdon effect on the nonlinear evolution of SBS in Au plasmas
Authors: Li Xiaoran , Qiu Jie , Zhang Shuqing , Hao Liang , Zou Shiyang 
Published: February 2025

Abstract
In laser-irradiated plasmas, the Langdon effect modifies the electron energy distribution function (EEDF) from a Maxwellian to a super-Gaussian form, further influencing backward stimulated Brillouin scattering (SBS). We investigate the impact of the Langdon effect on the nonlinear evolution of SBS in Au plasmas using Vlasov–Maxwell simulations, with a particular focus on electron–ion collisions. In the absence of electron–ion collisions, the higher ion acoustic wave (IAW) frequency associated with a super-Gaussian EEDF leads to a slower initial SBS growth rate compared to the Maxwellian case. As the IAW grows to higher amplitudes, higher-order harmonics and ion trapping occur, resulting in nonlinear frequency shifts and spectral broadening, which saturate SBS and maintain it at a quasi-steady state with relatively low reflectivity. Under a super-Gaussian EEDF, the reduced IAW nonlinearity and Landau damping contribute to a higher SBS saturation level. When electron–ion collisions are present, they weaken the rapid growth of the IAW and inhibit frequency shifts and spectral broadening, leading to a higher average reflectivity for the same initial EEDF. In this scenario, the Langdon effect further enhances SBS by reducing IAW nonlinearity and inverse bremsstrahlung (IB) absorption, in which reduced IAW nonlinearity leads to relatively weaker harmonics, and reduced IB absorption allows the pump wave to propagate with a relatively higher amplitude, significantly increasing SBS reflectivity.

Published: February 2025

Abstract
To address the limitations of traditional drilling equipment, such as large size, high power consumption, and difficulties with waterproofing, an underwater ultrasonic percussive drill (UUPD) based on piezoelectric drive is proposed. The structure and size parameters of the piezoelectric actuator are designed and its performance is experimentally verified. The maximum output amplitude of the piezoelectric actuator is 78.6 μm in air and 52.3 μm in water. Additionally, the dynamic characteristics of the UUPD are calculated theoretically and analyzed by simulation, and the influence of system parameters on vibration characteristics is revealed. A prototype of the UUPD is developed, and a performance testing platform is established, and drilling comparison experiments and power consumption test are carried out to evaluate the performance of the UUPD. Experimental results demonstrate that the UUPD is capable of breaking rocks with varying hardness (5–50 MPa) under small drilling pressure (around 6 N) and low power consumption (approximately 57 W). The UUPD proposed in this paper offers advantages, including low drilling pressure, low power consumption, light weight and compact structure, showing a good application prospect and providing an effective technical means for deep-sea hard mineral rock drilling and sampling.
Protecting quantum coherence of semiconductor qubit by utilizing charge noise

Published: February 2025

Abstract
Semiconductor qubits based on quantum dots (QDs) are a hopeful candidate for universal quantum computing due to their long coherence time and recent experimental achievements in precisely controlling and rapidly reading out the qubits. However, charge noise is an inevitable issue that leads to dephasing and relaxation in semiconductor qubits. In this paper, we propose a scheme to utilize these ubiquitous charge noises to protect quantum coherence. Our results reveal that introducing charge noise appropriately will not only be harmless to quantum coherence but may also reduce the decoherence caused by other factors, thus achieving the effect of protecting quantum coherence. We analyze the dynamics of double QDs coupled to a transmission line and focus on the charge noise acting on the QDs. For the flicker (

) charge noise, the numerical results indicate that a high-frequency noise is more suitable to protect coherence. Last but not least, we also investigate two other types of charge noise and show the performance of the mixed noise. We hope our results open a new window for the community to consider utilizing noise to protect quantum coherence.
