Abstract
Objectives The aims of this study were to analyze the clinical characteristics of patients with recurrent and metastatic sinonasal undifferentiated carcinoma (SNUC) and evaluate the current treatment strategies to help guide future management.
Design This is a retrospective cohort study.
Setting The study was conducted at six international tertiary treatment centers.
Participants Patients with documented diagnoses of recurrent or metastatic SNUC since 1983 were included in the study.
Main Outcome Measures Patient demographics and clinical characteristics were collected. Primary outcome measures included disease-specific survival (DSS), overall survival (OS), and time to recurrence (TTR) following initial treatment. Further univariable and multivariable analyses were performed to assess for prognostic factors.
Results A total of 97 patients with a mean (standard deviation [SD]) age of 52.4 (15.6) were identified, 15 of whom presented with metastatic SNUC and 90 of whom developed recurrence. Management in both populations was widely variable. For patients with metastatic disease, the 1-year DSS probability was 33.3% (95% confidence interval [CI], 10.8–100%). For patients with recurrent SNUC, the 1- and 5-year DSS probabilities were 45.7% (95% CI, 31.9–65.6%) and 8.6% (95% CI, 2.9–25.3%), respectively. The median (interquartile range [IQR]) TTR was 8 months (3–18.5 months). Multivariable analyses revealed a significant association between orbital involvement on initial presentation and TTR (hazard ratio [HR] = 3.28; 95% CI, 1.45–7.42; p = 0.004).
Conclusions To our knowledge, this is the first study addressing metastatic and recurrent SNUC based on a large patient cohort. Orbital extension of the primary SNUC may predict a higher probability of recurrence following treatment, suggesting the possible utility of a more aggressive treatment in this subgroup of patients. A heterogenous patient population and wide variability in management emphasize the challenges in standardizing care; however, dismal survival rates demonstrate the necessity for further evaluation of current approaches to improve evidence-based recommendations.
Exploring corporate reputation and crisis communication
Authors: Nuortimo Kalle , Harkonen Janne , Breznik Kristijan 
Published: October 2024

AbstractCorporate reputation, the collective perception of company attractiveness towards stakeholders, impacts business outcomes, while effective communication strategies play a critical role in shaping and maintaining the reputation. The role of communication is highlighted during crises, crisis communication being a strategic approach to managing and mitigating the impact of unexpected or adverse events on the reputation, operations, and stakeholders. These concepts are deeply interrelated with interactive marketing. This study explores the dynamics of corporate reputation and crisis communication during a recent global crisis by combining a literature review, opinion mining, and classification analysis. This is because stakeholders rely on various information sources and engage in online discussions, which can impact the reputation, and pose new challenges. The opinion mining analysis draws from the media communication of selected stock-listed companies during a crisis. The key findings shed light on the dynamics of corporate reputation and crisis communication and the impacts on interactive marketing. Critical components of crisis communication are identified to include monitoring, tactics of responding, and response management. Linkages between these, crisis communication theories, and corporate reputation are synthesised. Indications are provided on how the crisis can affect the corporate reputation and the significance of the speed of preventive communication measures.

This work presents an optoelectronic instrument designed for wireless visible light communication (WVLC) systems, operating within a wavelength range of 380–750 nm and compatible with standard radio frequency (RF) communication. The instrument encompasses two distinct architectures. The first enables the transmission and reception of RF-processed audio signals through a three-stage process involving RF signal transmission via Bluetooth, signal multiplexing using acousto-optic modulation, a sinusoidal grating, a PIN photodetector array, and final audio playback. The second architecture focuses on the wireless transmission and reception of temperature data, utilizing a similar three-stage approach that includes temperature data measurements with an LM35 sensor, signal processing with Arduino UNO microcontrollers, and information transmission via Bluetooth. Experimental results for both architectures validate the effectiveness of this optoelectronic instrument, demonstrating its capability to integrate RF and WVLC technologies.

Published: October 2024

In this paper, we demonstrate stable radio frequency (RF) transfer via metropolitan optical fiber link in the Beijing area. The phase variation of the RF signal is compensated by a phase conjugation method incorporating two high-performance phase-locked loops. The wavelength conversion module extends the transmission length to 200 km with only two parallel 50 km dark optical fibers available. We optimize the configuration of dispersion compensation and optical amplification due to the high loss (0.31 dB/km) of the optical fiber link. At the same time, comparative experiments verify the short-term instability limitation that arises from the group velocity dispersion of the optical fiber link. The measured standard Allan deviation of the 2.4 GHz RF transmission system with dispersion compensation is 4.5 × 10−14/1 and 2.6 × 10−17/20 000 s, which is superior to that of the reference rubidium clock. The short-term instability of the system is deteriorated to 2.5 × 10−13/1 s without dispersion compensation.

This paper reports on a monolithically integrated gallium arsenide (GaAs)-based photonic integrated circuit platform for wavelengths around 1064 nm. Enabled by spatially selective quantum well removal and two-step epitaxial growth, it supports on-chip gain as well as passive waveguides. In addition, shallow- and deep-etched waveguides are realized. The former result in waveguide losses of less than 2 dB/cm, while the latter enable compact integrated waveguide components. To demonstrate the performance of the platform, racetrack ring resonators based on deep-etched Euler bends and shallow-etched directional couplers are realized, achieving high intrinsic quality factors of 2.6 × 105 and 3.2 × 105 for the fundamental TE and TM mode, respectively. To demonstrate the use of these resonators, ring-resonator-coupled lasers are fabricated, resulting in one-sided output powers of up to 14 mW and single-mode operation with 40 dB side-mode suppression. The successful integration of ring resonators on a GaAs-based active/passive photonic integrated circuit platform paves the way for the realization of fully monolithic, widely tunable, and narrow linewidth ring-resonator-coupled laser sources.

Abstract
High-temperature superconducting coils are used in various large-scale applications, like rotating machines and high-field magnets. However, modeling these coils is a complicated and time-consuming process, especially due to the non-linearity of the current–voltage characteristics of the superconductors and the complex multiphysics involved. In this work, we used a fast homogenized method to model the coupled electromagnetic and electrothermal properties of racetrack and pancake coils for different applications. For this purpose, various formulations wielding homogenization methods are used and benchmarked with each other, as well as with models considering the detailed structure of the HTS tapes. We observe a very good agreement between different models (homogenized and detailed), and we discuss the pros and cons of the inclusion of insulating layers between the turns in homogenization. This work was performed under the collaboration of the COST action modeling teams and can be used as a review of the state-of-the-art superconductor modeling techniques, and a source for the development and benchmark of future numerical methods.
A study on breast cancer image classification based on particle swarm algorithm and transfer learning
Authors: Cai Yingying , Zhang Yong 
Published: October 2024

Abstract
Breast cancer is a major disease that poses a serious threat to the lives and health of women. A new framework was proposed to address the common challenges of high dimensional and data imbalances in image classification. This framework integrates particle swarm optimization (PSO) and transfer learning into a convolutional neural network model based on the ResNet34 architecture. The respective strengths complement each other to enhance the performance and efficiency of the classification model. Through parameter optimization and functional selection of PSO, the global search of the model has been improved. Transfer learning lets the model use large pre-trained datasets to learn more quickly on small sample datasets, which is especially helpful in areas where there are a lot of images that don’t have labels. Experimental findings reveal that our framework attains a 97.83% accuracy rate on the dataset and notably shortens the training cycle, demonstrating its effectiveness in improving breast cancer diagnosis performance with small sample sizes.

Abstract
Plasma discharges in the tungsten (W) Environment Steady-state Tokamak (WEST) are strongly impacted by W contamination. In WEST experiments, due to W contamination, the power radiated in the plasma (P
Rad) is on average, around 50% of the total power injected into the plasma (P
TOT). Furthermore, this radiated power fraction (f
Rad) is almost insensitive to plasma conditions. The causes behind this experimental trend are not fully understood. In this contribution, a 3D numerical model is used to analyze the W migration in the WEST boundary plasma in different plasma scenarios. The WEST experimental database is sampled to obtain a scan of simulation input parameters. These parameters mimic the WEST plasma conditions over a chosen experimental campaign. The simulation results are compared to WEST diagnostics measurements (reflectometry, Langmuir probes, and visible spectroscopy) to verify that the simulated plasma conditions are representative of the WEST database. The W contamination trend is analyzed: the W density (n
W) strongly decreases when the radial distance between the separatrix and WEST antennas (Radial Outer Gap, ROG) increases. On the other hand, at a given ROG, n
W increases proportionally with the power entering the scrape-off layer (P
SOL). P
Rad is estimated with a simple 0D model. For a fixed ROG, f
Rad is not sensitive to plasma conditions. These trends are qualitatively and, at times, quantitatively comparable to what is observed in WEST experiments: the simulated trends are related to the poorly screened W influx caused by the erosion of the main chamber Plasma-Facing Components. Thus, this numerical analysis suggests a possible interpretation of WEST experimental trends.
Separation of planar and edge contributions to total capacitance for accurate doping concentration determination in square silicon photodiodes

Published: October 2024

Abstract
Accurately determining the doping concentrations of silicon
photodiodes (PDs) is crucial for optimizing their performance in
various applications. This study presents a methodology for
separating the planar and edge contributions to the total
capacitance of square silicon PDs with guard rings. Through
capacitance-voltage measurements, we distinguished planar
capacitance, which reflects the bulk properties of the silicon PD,
from edge capacitance, influenced by device geometry and fringing
fields. We demonstrated that the fabricated PDs with guard rings
surrounding the active area could be effectively modeled using a
coxial-like structure to estimate edge capacitance. Doping
concentrations, depletion widths, and resistivities were determined
through linear fitting of the inverse square of the measured
capacitance per unit area as a function of the reverse bias voltage.
All parameters obtained from the full depletion voltage Vd
,
determined by the intersection of the linear fits for V < Vd
and
V > Vd
, demonstrated agreement within 1σ. Our results
underscore the importance of accounting for edge effects to
accurately determine doping concentrations from 1/C
2 vs. V
plots.

Published: October 2024

Abstract
The knowledge of the soil radon levels is important for the
planning and construction of new buildings in order to estimate the
radon risk and to classify the ground for construction purposes. A
simple device was developed to simulate the vertical migration of
radon in soil. The device simulates the vertical migration of radon
in two different cases. The first case: simulates radon vertical
migration in soil in a natural environment. The top of the device is
open, while the around and bottom are sealed. The second case:
simulates the vertical migration of radon in soil under the surface
of a concrete floor. The device is sealed all around, including the
top and bottom. A total of two sets of experiments were conducted in
this study, each set of experiments simulated the migration of radon
under two different cases. According to the research results, the
potential radon concentration under the concrete floor is much
higher than the natural potential radon concentration. Therefore,
this factor must be fully considered when selecting the building
materials and designing radon protection materials.

Abstract
Polyetheretherketone (PEEK), a high-performance special engineering plastic, has gradually been used in bone substitutes due to its wear resistance, acid and alkali resistance, non-toxicity, radiolucency, and modulus close to that of human bone. However, its stable biphenyl structure determines strong biological inertness, thus artificial interventions are required to improve the biological activity of fabricated PEEK parts for better clinical applications. This study developed a novel strategy for grafting bioactive glass (BAG) onto the surface of PEEK through sulfonation reaction with concentrated sulfuric acid (H2SO4), aiming to improve the bioactivity of printed porous bone scaffolds manufactured by fused deposition modeling to meet clinical individual needs. In vitro biological study was conducted on sulfonated PEEK-BAG scaffolds obtained by this strategy. The results demonstrated that the optimal modification condition was a 4 h sulfonation reaction with 1 mol l−1 concentrated H2SO4 at high temperature and high pressure. The scaffold obtained under this condition showed minimal cytotoxicity, and the Ca/P molar ratio, yield compressive strength, and compressive modulus of this scaffold were 2.94 ± 0.02, 62.78 MPa, and 0.186 GPa respectively. The presented method provides an innovative, highly effective, and customized strategy to improve the biocompatibility and bone repair ability of printed PEEK bone scaffolds for virous biomedical applications.

Abstract
Islands are hotspots of biological and cultural diversity that face growing threats from invasive species and climate change. Invasive mammal eradication on islands is a proven conservation intervention that prevents biodiversity loss and is a foundational activity for restoring degraded island-ocean ecosystems. However, these interventions are prioritized and evaluated primarily on biodiversity-based objectives despite growing evidence that invasive species removal may also serve as an effective nature-based solution to increase climate resilience of island-ocean ecosystems and contribute to climate change solution by protecting and restoring unique carbon stocks of native woody vegetation. To assess the effectiveness of interventions at the global scale, we developed a consistent and scalable framework for the long-term monitoring of tree cover, forest extent, forest carbon, and vegetation productivity in 1078 islands across 17 ecozones. Time-series of satellite-derived estimates of tree cover and the Normalized Difference Vegetation Index over 36 yr (1984–2020) were used to establish annual baselines and changes in forest extent, carbon stocks, and vegetation productivity. The analysis revealed significant and sustained positive trends in all the indices on islands with eradication. The magnitude and potential biological relevance of these effects was highly variable across ecozones, but the overall sustained effects provide strong evidence of a positive ecosystem response to invasive mammal removal. We also found that, collectively, these islands sustain more than 940 000 ha of forest and 53 million MgC of forest carbon. This novel framework enables measuring the climate co-benefits of island restoration interventions in relevant policy terms using a low cost and globally consistent methodology that is applicable across the range of spatial and temporal scales pertinent to ecosystem recovery dynamics on islands.
Assessing the complex influences of water management on hydrological drought characteristics in Texas
Authors: Yao Lili , Ferencz Stephen B , Sun Ning , Yan Hongxiang 
Published: October 2024

AbstractThe state of Texas in the United States is highly susceptible to drought. Its major rivers are subject to extensive water management (WM) activities in order to sustain multisectoral water demands, particularly during drought conditions. However, the impact of WM on the propagation dynamics and characteristics of hydrological drought (HD) in Texas remains unclear. To fill this gap, this study quantifies the influence of WM across 32 streamflow gauges along the mainstems of seven major rivers in Texas by comparing a variety of drought metrics under natural and managed conditions. Notably, we leveraged an extensive, naturalized streamflow dataset constructed by the Texas Commission on Environmental Quality, paired with gauge observations of managed conditions. Results indicate that at the multi-decadal scale, WM significantly reduced HD frequency across all seven rivers and at 81% of the gauges analyzed. Additionally, it increased the response timescale of HD across Texas’ major rivers by a median of 2.5 months. Conversely, the average-event duration and severity increased in most locations. Temporal analysis reveals that the WM impact on HD varied seasonally, with attenuation effects during mid-summer and early fall and intensification effects during late winter and spring. Additionally, WM was found to greatly increase the spatial variability of HD characteristics across the region. These findings emphasize the complexity of WM effects on HD and the necessity for nuanced strategies in managing HD under WM influences.

Abstract
Nobel metals are commonly used catalysts in reactions due to their excellent catalytic activities. Transition metals, too, possess good catalytic activity due to the availability of vacant d-orbitals that provide avenues for electron exchange during reactions. In this work, the performance of CuO/Co3O4 (CCO) catalyst is evaluated. The catalyst is prepared by a facile coprecipitation method. X-ray diffraction, Fourier transform infrared spectroscopy, HRTEM, Ultraviolet spectroscopy, Scanning electron microscopy and X-ray photoelectron spectroscopy techniques were used to study the material properties. XRD analysis confirms the formation of CCO heterostructure with supporting evidence from FTIR, HRTEM and XPS. The catalyst shows optical bandgap contributions of CuO and Co3O4 at 1.6 eV and 2.4 eV, respectively. The SEM analysis shows the presence of agglomerates with a mean length of 111 ± 3 nm. The prepared catalyst is employed for the 4-nitroaniline reduction using sodium borohydride. The kinetics of the reduction reaction were studied, and an apparent rate constant of 0.323 min−1 was estimated. The catalyst shows a turnover frequency of 1.44 min−1 and 100% recyclability up to 5 cycles that are competitive with noble metal and rare-earth-based catalysts. The fast reduction of 4-NA is attributed to the novel p-p type isojunction formed by the heterostructure of CCO. Additionally, extensive electrochemical analysis has been used as an in situ probe to monitor the reduction reaction. Accordingly, the study shows the different intermediary reduction species formed in the process of reduction, adding evidence to the proposed mechanism.
