Abstract
We present absolute L-shell photoionisation cross sections for the S+, S2+, S3+ ions. The cross sections were obtained using the monochromatised photon beam delivered by the SOLEIL syn- chrotron source coupled with an ion beam extracted from an electron cyclotron resonance source (ECRIS) in the merged dual-beam configuration. The cross sections for single, double and triple ionisation were measured and combined to generate total photoionisation cross sections. For each of the S+, S2+ and S3+ ions, the photon energy regions corresponding to the excitation and ionisation of a 2p or a 2s electron (∼ 175-230 eV) were investigated. The experimental results are interpreted with the help of multiconfigurational Dirac-Fock (MCDF) and Breit-Pauli R-Matrix (BPRM) or Dirac R-Matrix (DARC) theoretical calculations. The former generates photoabsorption cross sec- tions from eigenenergies and eigenfunctions obtained by solving variationally the multiconfiguration Dirac Hamiltonian while the latter calculate cross sections for photon scattering by atoms. The cross sectional spectra feature rich resonance structures with narrow natural widths (typically ≤ 100 meV) due to 2p → nd excitations below and up to the 2p thresholds. This behaviour is consistent with the large number of inner-shell states based on correlation and spin-orbit mixed configurations hav- ing three open subshells. Strong and wide (typically ∼ 1 eV) Rydberg series of resonances due to 2s → np excitations dominate above the 2p threshold.

Published: February 2025

Abstract
In this study, mesoporous MgO nanoparticles were successfully synthesized using carbon quantum dots as templates and an outstanding cataluminescence sensor system was established based on these nanoparticles. In a particular situation, the constructed sensor demonstrated remarkable linear range was 0.3106–310.6 ppm (R2
= 0.9990) with a low limit of detection of 0.0994 ppm and a signal-to-noise ratio (S/N) of 3. The mesoporous MgO nanoparticle sensor was utilized to analyze the isobutyraldehyde content in real samples. Outstanding recoveries were achieved within range of 83.4%–111%, with the relative standard deviations (n = 7) ranging from 2.0% to 8.2%. Moreover, the 35 d test results showed that the sensor has good stability. Density functional theory and gas chromatography-mass spectrometry were used to research the mechanism of the designed cataluminescence sensor. This work presents a universal methodology for constructing isobutyraldehyde gas sensors with high sensitivity and selectivity, and mesoporous MgO nanoparticles sensors that expand the applications available in the industry and environment analysis.

The low-frequency and broad bandgap characteristics of two-dimensional phononic crystals embedded with acoustic black hole structures
Authors: Liu Xi-Xuan , Yan Wan-Ru , Xu Yao-dong , Liu Zi-Jiang 
Published: February 2025

Abstract
To address the challenge of controlling low-frequency vibration noise, a coupling phononic crystal model embedded with the acoustic black hole (ABH) structures has been designed. By comprehensively studying the complex dispersion curves, vibration modes, and transmission loss, we numerically demonstrate that this coupling structure exhibits good sound insulation performance in the low-frequency range of 64.3 Hz∼665.4 Hz, the bandgap coverage reaches 92.7%, while the effective sound insulation range achieves 89.6% within the frequency range of 1000 Hz. The torsional vibration of the scatterer component is more conducive to the lowering of the first starting frequency, and a larger torsion angle further contributes to this reduction. However, the cutoff frequency of the first bandgap is predominantly caused by the oscillating along the z-direction of the ABH structure. Evanescent waves exist in all the studied frequency bands exhibiting a strong correlation with the complex dispersion curve and the transmission loss. The intensity of the evanescent wave depends on the activated state of the ABH structures, the lower imaginary part of the complex dispersion curve corresponding to the passband yields the lower energy loss caused by the evanescent wave. Damping materials benefit the energy loss caused by evanescent waves. Parameters dependence of the ABH truncation thickness, the length of bending component and uniform part are analyzed, which are expected to provide theoretical design guidance for the control and attenuation of low-frequency vibration and noise.

Published: February 2025

Abstract
We report on characterization results for our new silicon photonic chip for high-speed data transmission, called COTTONTAIL (Chip for detector instrumentation with wavelength division multiplex). Modulation bandwidths of different travelling-wave Mach-Zehnder modulators and ring resonator modulators are sufficient for very high data transmission rates. Bit error rate measurements were conducted with a very low voltage swing of 1.1 V
pp
and error free transmissions could be established up to a data rate of 11.3 Gb/s with the ring modulators and up to 8.5 Gb/s with the Mach-Zehnder modulators. Wavelength filters for wavelength division multiplexing show a very low transmission loss of less than 2.3 dB with a slight wavelength shift of the filtering characteristics. Also included photodiodes are well suited for high speed downlinks with data rates in excess of 40 Gb/s or on-chip modulator monitoring.
Decadal predictions outperform climate projections in forecasting Mediterranean wintertime precipitation
Authors: Nicolì Dario , Gualdi Silvio , Athanasiadis Panos J 
Published: February 2025

Abstract
The Mediterranean region is highly sensitive to climate change, having experienced an intense warming and drying trend in recent decades. In the context of decision-making processes, there is growing interest in understanding the near-term climate evolution of this region. Climate change projections consistently indicate that Southern Europe and the Mediterranean region will undergo significantly drier conditions in the latter half of the 21st century. However, in considering the upcoming decade, a critical question arises: Are climate change projections the best product for understanding climate evolution in the near future? This is a matter of great importance for numerous stakeholders and decision-makers. In this study, using retrospective forecasts from eight decadal prediction systems contributing to the CMIP6 Decadal Climate Prediction Project and the corresponding ensemble of non-initialized simulations (historical and projections), we compare the capabilities of the state-of-the-art climate models in predicting the near-term climate anomalies of the wintertime Mediterranean region for some key quantities, also assessing the added value of initialization. Our findings indicate the superior performance of the decadal predictions, exhibiting higher skill than uninitialized historical simulations and projections, particularly over the North Atlantic subpolar gyre for surface temperature and over Southern Europe for precipitation. We also develop a hybrid (dynamical-statistical) model to explore the role of the North Atlantic Oscillation and subpolar sea surface temperatures on Mediterranean precipitation predictability. It is shown that the developed hybrid model further enhances predictive skill, underscoring the importance of using initialized decadal predictions for precipitation across Europe and the Mediterranean region.
Polarized light-sensitive optoelectronic synapses for expanding artificial vision systems
Authors: Choi Ji-Hoon , An Hye-Min , Park Hea-Lim 
Published: February 2025

Abstract
Flexible material-based artificial vision systems are gaining increasing attention due to their potential in applications requiring operation on curved surfaces, such as autonomous vehicles, smart healthcare devices, and humanoid robot eyes. However, conventional vision systems built on the von Neumann architecture encounter significant limitations in energy efficiency and processing speed. To overcome these challenges, optoelectronic synapses inspired by biological visual systems have emerged as a promising alternative. These synapses enhance data processing speed and reduce system complexity by enabling real-time analysis of optical signals, including wavelength and light intensity. Moreover, integrating polarized light sensing function into such systems offers a substantial performance boost. Polarized light, which carries additional directional information, facilitates advanced applications like precise image recognition and navigation. This review focuses on polarized light-sensitive (PLS) optoelectronic synapses, emphasizing the role of flexible materials in expanding the capabilities of existing systems. We begin by exploring diverse strategies for achieving polarization detection, focusing on material selection and fabrication processes. This is followed by an in-depth discussion of the mechanisms underlying PLS optoelectronic synapses.
Left main stem disease: PCI versus CABG.What about medical management? – a case report
Authors: Kaczmarska-Dyrda Edyta , Rudziński Piotr Nikodem , Dębski Mariusz , Dzielińska Zofia , Demkow Marcin 
Published: February 2025

Abstract

Background
Optimal strategy for treating bifurcation lesions in the left main coronary artery (LMCA) remains elusive.

Case summary
We describe a 66-year-old Caucasian male with a risk factors for coronary artery disease, but free of angina, who presented to the hospital after syncope and nsVT diagnosis in the 24h Holter electrocardiography monitoring. Coronary computed tomography angiography (CCTA) revealed LMCA bifurcation stenosis with concomitant left circumflex (LCx) and diagonal branch (DB) stenosis. Subsequent coronary angiography confirmed diagnosis. Successful percutaneous coronary intervention (PCI) of bifurcation/distal LMCA disease involving ostium of LAD and LCx has been a challenging procedure.

Discussion
Current guidelines still favor coronary artery bypass grafting (CABG) over PCI for revascularization in LMCA stenosis. However, great progress has been made on PCI, therefore it has become the compelling alternative procedure to CABG for the LMCA bifurcation stenosis in appropriately selected patients.

Abstract
The May Measurement Month (MMM) campaign was carried out in Vietnam in 2022 with the aim of raising awareness of increased blood pressure (BP). Here, we report on the findings of the campaign.
Adults aged ≥ 18 years were recruited opportunistically from 14 provinces and cities in Vietnam. Three seated BP readings were taken for each participant along with the completion of a questionnaire on demographics, lifestyle factors, and comorbidities. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, or use of antihypertensive medication. Controlled BP was defined as the use of antihypertensive medication with a BP of &lt;140/90 mmHg. Multiple imputations were used to estimate the missing BP readings. In total, 11 796 were screened, with a mean age of 51.9 years and 58.2% were female. Of all participants, 4276 (36.2%) had hypertension, of whom 3232 (75.6%) were aware, and 2947 (68.9%) were on antihypertensive medication. Of those on antihypertensive medication, 1297 (44.0%) had controlled BP; of all participants with hypertension, 30.3% had controlled BP. In total, 2979 (25.3%) were found to have either untreated or inadequately treated hypertension.
Meeting physical activity guidelines was associated with lower systolic BP (-2 mmHg, p&lt;0.001), and having 12 or more years of education was associated with lower diastolic BP (-1.8 mmHg, p&lt;0.001), while alcohol consumption, particularly at moderate to high frequencies, was positively associated with both systolic BP (p=0.005) and diastolic BP (p=0.010). Hormone replacement therapy use among women showed a positive association with both systolic (3.8 mmHg, p=0.005) and diastolic (2.6 mmHg, p=0.009) BP.
The MMM campaign in Vietnam identified a significant number of participants with untreated or inadequately treated hypertension. The need for targeted public health initiatives in Vietnam focused on hypertension awareness, lifestyle modification, and better management practices to enhance BP control.

Abstract

Study Objectives
Insufficient/irregular sleep patterns are common conditions, but their cardiovascular consequences and strategies to minimize these risks are poorly explored. We aimed to determine whether weekend sleep extension (catch-up sleep) and social jetlag may impact the incidence of subclinical atherosclerosis.

Methods
We performed a 7-day wrist actigraphy in this cohort study to monitor sleep parameters. Coronary artery calcium (CAC) was measured at two different time points. Catch-up-sleep was measured by calculating weekend minus weekday sleep duration. Social jetlag was calculated by the difference between the mean sleep midpoint on weekend days minus weekdays. The incidence of subclinical atherosclerosis was defined as baseline CAC=0, followed by CAC&gt;0 at the follow-up. The association of incident CAC outcome was assessed using logistic regression adjusting for traditional confounders plus sleep apnea.

Results
We analyzed 1,832 participants (age: 48.8±8.0 years; 57.8% women). Incidence of CAC among subjects with catch-up sleep &gt;90 and ≤90 minutes were 19.1% vs. 31.7%, respectively (P&lt;0.001). In covariate-adjusted analyses (follow-up=5.4±0.90 years), we found a lower incidence of CAC in those participants with catch-up-sleep &gt;90 minutes (OR=0.62; 95% CI 0.52–0.74). Interestingly, stratified analysis revealed that these results are modified by sleep duration (≤6.55 hours: OR=0.42; 95% CI 0.33–0.54; &gt;6.55 hours: OR=0.96; 95% CI 0.75–1.24). In contrast, social jet lag was weakly associated with incident CAC: 0.1% increasing risk/minute.

Conclusions
Extending sleep time during the weekend is independently associated with lower 5-year CAC incidence, providing relevant insights into the cardiovascular benefits of this common sleep habit Worldwide.

Abstract
Chronic insomnia is a prevalent sleep disorder where &lt;1% of patients receive the recommended first line treatment; Cognitive Behavioural Therapy for Insomnia. Digital technologies and self-managed therapies are scalable solutions to address this critical gap in patient care, but it is difficult to select which therapies are best. This study will test the comparative efficacy and cost-benefits of Intensive Sleep Retraining administered by THIM sleep tracker, SHUTi treatment program, and their combination (THIM then SHUTi) versus a waitlist control group. This study is a 4 (treatment: +/- THIM and +/- SHUTi) x 3 (time: pre-treatment, post-treatment, two-month follow up) randomised controlled trial. Participants who meet diagnostic criteria for Chronic Insomnia Disorder will be randomised to one of four groups. Sleep and daytime functioning symptoms will be assessed via self-report daily and weekly questionnaires, and objective sleep trackers during treatment and for two weeks pre- and post-treatment and at two-month follow up. The primary outcome is total wake time, with a reduction of ≥ 30 minutes considered a clinically meaningful difference. For the primary analysis, the interaction between treatment group and time on total wake time will be analysed using repeated measures ANOVA. This project was approved by the Southern Adelaide Clinical Human Research Ethics Committee (2021/HRE00414) and registered in the Australian and New Zealand Clinical Trials Registry (ACTRN12622000778785). As the first study to investigate the comparative efficacy of two different technology-enabled treatments for insomnia, this study will help inform clinicians and public health policy regarding the use case for public and private health-funded technology-enabled options for insomnia.
Effects of lung expansion on global and regional pulmonary blood volume in a sheep model of acute lung injury
Authors: Zang Mingyang , Zeng Congli , Lagier David , Leng Nan , Grogg Kira , Motta-Ribeiro Gabriel , Laine Andrew F. , Winkler Tilo , Vidal Melo Marcos F. 
Published: February 2025

Background:
Pulmonary capillary blood volume is a major determinant of lung gas transport efficiency, and also potentially related to ventilator-induced lung injury. Yet, knowledge on how lung expansion influences pulmonary blood volume in injured lungs is scant. We hypothesize that lung expansion produced by positive end-expiratory pressure (PEEP) modulates the global and regional spatial distribution of pulmonary blood volume.

Methods:
In a lung injury model exposed to distinct lung expansion within clinical range (PEEP=5-20 cmH2O), we aimed to determine whole-lung and regional blood volume, their dynamic changes, and association with gas volume changes. Seven healthy sheep were subjected to 3h of low-lung volume mechanical ventilation at PEEP=0 cmH2O and systemic endotoxemia. PEEP=5 (low), 20 (high), and 12 (intermediate) cmH2O were applied to produce distinct lung expansion. Respiratory-gated positron emission tomography with 11C-labelled carbon monoxide and 4-dimensional computed tomography were obtained to quantify blood volume and aeration.

Results:
Transpulmonary pressures were lowest at PEEP=12 cmH2O. Changes in whole-lung blood volume correlated with gas volume changes between PEEP=5 and 12 cmH2O at end-expiration (P<0.001) and end-inspiration (P<0.001), but not between PEEP=12 and 20 cmH2O. Tissue-normalized blood volume (VBtissue

) was heterogeneously distributed, with mean values in non-dependent regions (VBtissue

=0.116±0.055) approximately 7-times smaller than those in mid-dependent regions (VBtissue

=0.832±0.132). PEEP=12 cmH2O resulted in the most homogeneous VBtissue

distribution, with largest means in mid-dependent regions and inspiratory 10th-percentile, a measure of lowest values, throughout the lung. VBtissue

increased with inspiration at PEEP=5 and 12 cmH2O but decreased with PEEP=20 cmH2O in mid-nondependent regions.

Conclusions:
During low-volume mechanical ventilation and systemic endotoxemia, lung blood volume is markedly heterogeneously distributed, and modulated by PEEP. Nondependent regions are susceptible to low blood volume and capillary closure. Recruitment of pulmonary vascular blood volume with gas volume is nonlinear, limited at intermediate PEEP indicating its advantage to spatial distribution of blood volume.

Authors: Tse David T. , Wang Hua , Tao Wensi , O’Brien Robert C. , Tse Brian C. , Pelaez Daniel 
Published: February 2025

Purpose:
To test a novel early polytherapy treatment strategy targeting mitochondrial bioenergetics, glutamate excitotoxicity, and sterile inflammatory response molecular pathways associated with retinal ganglion cell survival following optic nerve trauma.

Methods:
Twenty C57BL/6J mice were subjected to sonication-induced traumatic optic neuropathy injury. The control group (n = 10) received intravitreal, retrobulbar, and subcutaneous phosphate buffered saline injections on days 0 and 3 (no repeat retrobulbar vehicle). On day 0, the treatment group (n = 10) received injections of intravitreal interleukin-1 receptor antagonist with ketamine, retrobulbar ropivacaine, and subcutaneous etanercept. Treatment group animals had 1% (wt/vol) N-acetylcysteine ad libitum supplemented in drinking water from day 1. On day 3, intravitreal pan-ephrin receptor antagonist peptide and subcutaneous elamipretide and etanercept injections were given. Pattern electroretinogram assessments continued at weeks 0, 1, 2, 4, 6, 8, 10, and 12. Optical coherence tomography retinal layer thickness was measured on naive, control, and treatment groups at week 12. The whole mount retinas were harvested for retinal ganglion cell quantitation.

Results:
At 12 weeks, the averaged retinal ganglion cell density count in the control group was lower (413.37 ± 41.77 cells/mm2) compared with treatment (553.97 ± 18.00 cells/mm2; p < 0.001) and naive (595.94 ± 30.67cells/mm2; p < 0.001) groups. Ganglion cell complex layer thicknesses showed control group (49.29 ± 5.48 μm) thinner than the treated (61.00 ± 2.57 μm; p = 0.004) and naive (67.00 ± 6.12 μm; p = 0.004) groups. No significant difference was seen at 12 weeks between the treated and naive groups. Pattern electroretinogram recordings in the control group revealed a statistically significant decrease in amplitudes for all time points. Apart from week 8, the amplitudes in the treatment group did not significantly differ from the baseline at any time point.

Conclusions:
Early combinatorial therapeutic intervention to address disparate molecular pathways following optic nerve trauma effectively halts retinal neurons’ progressive structural and functional degeneration.
