AbstractJakarta Greater Area (JGA) has encountered recurrent challenges of air pollution, notably, high ozone levels. We investigate the trends of surface ozone (O3) changes from the air quality monitoring stations and resolve the contribution of meteorological drivers in urban Jakarta (2010–2019) and rural Bogor sites (2017–2019) using stepwise Multi Linear Regression. During 10 years of measurement, 41% of 1-h O3 concentrations exceeded Indonesia’ s national threshold in Jakarta. In Bogor, 0.1% surpassed the threshold during 3 years of available data records. The monthly average of maximum daily 8-h average (MDA8) O3 anomalies exhibited a downward trend at Jakarta sites while increasing at the rural site of Bogor. Meteorological and anthropogenic drivers contribute 30% and 70%, respectively, to the interannual O3 anomalies in Jakarta. Ozone formation sensitivity with satellite demonstrates that a slight decrease in NO2 and an increase in HCHO contributed to declining O3 in Jakarta with 10 years average of HCHO to NO2 ratio (FNR) of 3.7. Conversely, O3 increases in rural areas with a higher FNR of 4.4, likely due to the contribution from the natural emission of O3 precursors and the influence of meteorological factors that magnify the concentration.

Published: April 2024

AbstractThe nasal potential difference test (nPD) is an electrophysiological measurement which is altered in patients and animal models with cystic fibrosis (CF). Because protocols and outcomes vary substantially between laboratories, there are concerns over its validity and precision. We performed a systematic literature review (SR) of the nPD to answer the following review questions: A. Is the nasal potential difference similarly affected in CF patients and animal models?”, and B. “Is the nPD in human patients and animal models of CF similarly affected by various changes in the experimental set-up?”. The review protocol was preregistered on PROSPERO (CRD42021236047). We searched PubMed and Embase with comprehensive search strings. Two independent reviewers screened all references for inclusion and extracted all data. Included were studies about CF which described in vivo nPD measurements in separate CF and control groups. Risk of bias was assessed, and three meta-analyses were performed. We included 130 references describing nPD values for CF and control subjects, which confirmed substantial variation in the experimental design and nPD outcome between groups. The meta-analyses showed a clear difference in baseline nPD values between CF and control subjects, both in animals and in humans. However, baseline nPD values were, on average, lower in animal than in human studies. Reporting of experimental details was poor for both animal and human studies, and urgently needs to improve to ensure reproducibility of experiments within and between species.

Published: April 2024

AbstractDirect Laser Interference Patterning (DLIP) stands out as a versatile and cost-effective method for functionalizing material surfaces at high throughputs. Monitoring the dynamics of the structure formation can lead to a deeper understanding of the interplay between the main factors governing the process and ultimately to optimize the final texture. Here, the formation of gratings on stainless steel by DLIP with ns-pulses is studied using a diffraction-based approach, which measures the time-resolved reflectivity (TRR) of the sample. Measurements are performed for single pulses across different laser fluences. The melting dynamics are analyzed and compared with numerical results. By correlating the recorded signals with the structure depths, growth rates of 11 nm/ns and 57 nm/ns were estimated for fluences of 1.9 J/cm2 and 5.3 J/cm2, respectively. Furthermore, two growth regimes are identified. In the fast growth phase, the melting time increased from 73 to 380 ns for fluences of 1.9 J/cm2 and 5.9 J/cm2, respectively, showing a good agreement with the performed thermal simulations.
Enhancing hydrogen generation from sodium borohydride hydrolysis and the role of a Co/CuFe2O4 nanocatalyst in a continuous flow system
Authors: Mirshafiee Faezeh , Rezaei Mehran 
Published: April 2024

AbstractIn this study, a series of cobalt-based spinel ferrites catalysts, including nickel, cobalt, zinc, and copper ferrites, were synthesized using the sol–gel auto-combustion method followed by a chemical reduction process. These catalysts were employed for accelerating hydrogen generation via the sodium borohydride hydrolysis process. A continuous stirred tank reactor was used to perform catalytic reactor tests. All samples were subjected to analysis using XRD, FESEM, EDX, FTIR, and nitrogen adsorption–desorption techniques. The results revealed that the cobalt-based copper ferrite sample, Co/Cu-Ferrite, exhibited superior particle distribution, and porosity characteristics, as it achieved a high hydrogen generation rate of 2937 mL/min.gcat. In addition, the higher electrical donating property of Cu-Ferrite which leads to the increase in the electron density of the cobalt active sites can account for its superior performance towards hydrolysis of NaBH4. Using the Arrhenius equation and the zero-order reaction calculation, activation energy for the sodium borohydride hydrolysis reaction on the Co/Cu-Ferrite catalyst was determined to be 18.12 kJ/mol. This low activation energy compared to other cobalt-based spinel ferrite catalysts confirms the catalyst's superior performance as well. Additionally, the outcomes from the recycling experiments revealed a gradual decline in the catalyst's performance after each cycle during 4 repetitive cycles. The aforementioned properties render the Co/Cu-Ferrite catalyst an efficient catalyst for hydrogen generation through NaBH4 hydrolysis.

AbstractBased on dynamic monitoring data on China’s population, by using complex networks, spatial analysis and mathematical measurement, this study reveals the spatial characteristics and influencing factors of the network of flows of highly educated talents in the Yangtze River Delta region from the national and local perspectives. In the two perspectives, the network has strong isomorphism and certain differences. The in-flow of highly educated talents from cities with high administrative levels and more developed economies to Shanghai constitutes the core of the entire network. From a national perspective, highly educated talents tend to converge to the Yangtze River Delta region. From a local perspective, it was found that these talents cluster towards a limited number of cities in the region. From both perspectives, the flow network has developed into a “core-periphery” progressive hierarchical structure, with Shanghai becoming the sole core city. There is little difference in the influencing factors of talent mobility from both macro and meso perspectives. Highly educated talents would frequently flow between cities with strong economic development levels, and cities with high education level, scientific and technological level, complete infrastructure, and good aesthetics. However, geographical distance still plays a hindering role in the flow of highly educated talents, and factors such as cultural identity, institutional, and social modality differences among regions also have a certain effect on the flow of these talents.

AbstractToll-like receptor 9 (TLR-9) is a protein that helps our immune system identify specific DNA types. Upon detection, CpG oligodeoxynucleotides signal the immune system to generate cytokines, essential proteins that contribute to the body’s defence against infectious diseases. Native phosphodiester type B CpG ODNs induce only Interleukin-6 with no effect on interferon-α. We prepared silicon quantum dots containing different surface charges, such as positive, negative, and neutral, using amine, acrylate-modified Plouronic F-127, and Plouronic F-127. Then, class B CpG ODNs are loaded on the surface of the prepared SiQDs. The uptake of ODNs varies based on the surface charge; positively charged SiQDs demonstrate higher adsorption compared to SiQDs with negative and neutral surface charges. The level of cytokine production in peripheral blood mononuclear cells was found to be associated with the surface charge of SiQDs prior to the binding of the CpG ODNs. Significantly higher levels of IL-6 and IFN-α induction were observed compared to neutral and negatively charged SiQDs loaded with CpG ODNs. This observation strongly supports the notion that the surface charge of SiQDs effectively regulates cytokine induction.

Published: April 2024

AbstractCommercial adiabatic demagnetisation refrigerators still employ the same hydrated salts that were first introduced over 85 years ago. The inherent limitations of these insulating magnetocalorics – poor thermal conductivity at sub-Kelvin temperatures, low entropy density, corrosiveness – can be overcome by a new generation of rare-earth based metallic magnetocalorics. Here, we present the metallic magnetocaloric YbNi1.6Sn as an attractive alternative to conventional refrigerants. YbNi1.6Sn retains high entropy into the 100 mK regime and avoids the noble metal constituents of alternative refrigerants. Demagnetisation tests demonstrate that YbNi1.6Sn enables economical and durable alternatives to traditional cooling devices for temperatures reaching below 120 mK. We find that the magnetocaloric properties of this material are facilitated by unusually small Kondo and RKKY interactions, which position YbNi1.6Sn in the extreme local moment limit on the generalised Kondo lattice phase diagram.
Correlation of Grading and Number of Ear Subunits With Auditory Brainstem Response Findings in Children With Microtia
Authors: Widodo Dini Widiarni , Zizlavsky Semiramis 
Published: April 2024

Purpose:
The association between microtia severity and hearing function has been thoroughly investigated. This study examined the relationship between microtia grade, number of ear subunits (i.e., helix, antihelix, scapha, triangularis fossa, concha, lobule, tragus, and antitragus) with auditory brainstem response (ABR) findings in children with microtia.

Study Design:
A retrospective chart review was employed in this study.

Method:

We analyzed the ABR test results and photographs of 22 children with 30 microtia ears at Dr. Cipto Mangunkusumo National Hospital, Jakarta. The ABR test results were acquired using click (air conduction only) and 500-Hz tone burst stimuli (air- and bone-conduction). Ear photographs were overlaid with a template of a normal ear to determine the number of ear subunits present and the subsequent microtia grade. Number of ear subunits and ABR results were analyzed using the chi-square, Mann–Whitney
U
, and Spearman's correlation tests.

Results:
ABR thresholds for click and 500-Hz tone bursts air-conduction were significantly poorer for ears with a subunit < 5 compared to ears with a subunit ≥ 5. No significant difference was observed in 500 Hz bone-conduction ABR thresholds between these groups. Correlation analysis showed a significant negative correlation between increased ear subunits and click ABR thresholds. No significant correlation was found between ear subunits and 500-Hz air- and bone-conduction ABR thresholds.

Conclusions:
A higher number of ear subunits are associated with a lower hearing threshold, as assessed using ABR with click stimuli. Therefore, the number of ear subunits and microtia grades can be used to examine the hearing level thresholds in infants and children with microtia.

Core loss determination in electric machines using short‐time transient thermal measurements

Published: April 2024

AbstractThis paper introduces a novel application of the inverse modelling method, which is designed to estimate core losses in both the stator and rotor regions of an electrical machine. The technique focuses on the use of short‐term transient temperature measurements obtained from the stator core of a slotless induction machine, with a focus on validating the measured temperature rise through a forward model. The measurement setup involves two primary approaches: (i) the use of thermal sensors embedded in a printed circuit board inside the stator core and (ii) surface sensors embedded on the stator yoke. Through the use of this innovative approach, the results indicate that the inverse modelling technique is highly effective in predicting core losses based on short‐time transient temperature rise measurements.

Context. The hydrogen deuteride (HD) molecule is an important deuterium tracer in astrophysical studies. The atmospheres of gas giants are dominated by molecular hydrogen, and the simultaneous observation of H2 and HD lines provides reliable information on the D/H ratios on these planets. The reference spectroscopic parameters play a crucial role in such studies. Under the thermodynamic conditions encountered in these atmospheres, spectroscopic studies of HD require not only the knowledge of line intensities and positions but also accurate reference data on pressure-induced line shapes and shifts.
Aims. Our aim is to provide accurate collision-induced line-shape parameters for HD lines that cover any thermodynamic conditions relevant to the atmospheres of giant planets, namely any relevant temperature, pressure, and perturbing gas composition (the H2–He mixture).
Methods. We performed quantum-scattering calculations on our new, highly accurate ab initio potential energy surface (PES), and we used scattering S matrices obtained in this way to determine the collision-induced line-shape parameters. We used cavity ring-down spectroscopy to validate our theoretical methodology.
Results. We report accurate collision-induced line-shape parameters for the pure rotational R(0), R(1), and R(2) lines, the most relevant HD lines for investigations of the atmospheres of the giant planets. Besides the basic Voigt-profile collisional parameters (i.e., the broadening and shift parameters), we also report their speed dependences and the complex Dicke parameter, which can influence the effective width and height of the HD lines up to almost a factor of 2 for giant planet conditions. The sub-percent-level accuracy reached in this work is a considerable improvement over previously available data. All the reported parameters (and their temperature dependences) are consistent with the HITRAN database format, hence allowing for the use of the HITRAN Application Programming Interface (HAPI) for generating the beyond-Voigt spectra of HD.

Context.Gaia cannot individually resolve very close binary systems; however, the collected data can still be used to identify them. A powerful indicator of stellar multiplicity is the sources’ reported re-normalised unit weight error (RUWE), which effectively captures the astrometric deviations from single-source solutions.
Aims. We aim to characterise the impact of binarity on the RUWE. By flagging potential binary systems based on RUWE, we aim to determine which of their properties will contribute the most to their detectability.
Methods. We developed a model to estimate the RUWEs for observations of Gaia sources, based on the biases to the single-source astrometric track arising from the presence of an unseen companion. Then, using the recipes from previous GaiaUnlimited selection functions, we estimated the selection probability of sources with high RUWEs, and discussed what binary properties contribute to increasing the sources’ RUWEs.
Results. We computed the maximum RUWE that is compatible with single-source solutions as a function of their location on-sky. We see that binary systems selected as sources with a RUWE higher than this sky-varying threshold have a strong detectability window in their orbital period distribution, which peaks at periods equal to the Gaia observation time baseline.
Conclusions. We demonstrate how our sky-varying RUWE threshold provides a more complete sample of binary systems when compared to single sky-averaged values by studying the unresolved binary population in the Gaia Catalogue of Nearby Stars. We provide the code and tools used in this study, as well as the sky-varying RUWE threshold, through the GaiaUnlimited Python package.

Zusammenfassung
Hintergrund Durch die Einführung neuartiger Operationsroboter und
Operationsmikroskope für die speziellen Bedürfnisse der offenen Mikrochirurgie
gewinnt das Konzept der robotisch-assistierten Mikrochirurgie zunehmend an
Popularität. Während initiale präklinische Studien auf eine steile Lernkurve,
vorteilhafte Ergonomie und verbesserte Präzision bei jedoch verlängerter
Operationszeit hindeuten, sind die Daten über die klinische Anwendung der neuen
Systeme noch limitiert. Diese Studie beschreibt unsere erste klinische Erfahrung
mit der robotisch-assistierten autologen Brustrekonstruktion und stellt die
Chancen und Limitationen des Ansatzes dar.
Patienten und Methoden Es wurden insgesamt 28 Patientinnen in die
retrospektive Datenauswertung eingeschlossen, die im Zeitraum von Juli 2022 bis
August 2023 eine einseitige robotisch-assistierte autologe Brustrekonstruktion
erhielten. Dabei wurde ein kombinierter Ansatz unter Verwendung des Symani
Surgical Systems zusammen mit dem RoboticScope angewandt. Es erfolgte die
deskriptive Auswertung der Patienteneigenschaften, Operationsdaten und
Komplikationen.
Ergebnisse Das Durchschnittsalter der Patientinnen betrug 54,3±11,1 Jahre
mit einem durchschnittlichen BMI von 26,5±3,5 kg/m2. 26 Patientinnen
erhielten eine DIEP-Lappenplastik und 2 Patientinnen eine PAP-Lappenplastik, die
in 22 Fällen an die A. mammaria interna, in 5 Fällen an einen Perforator der A.
mammaria interna und in einem Fall an einen Ast der A. thoracodorsalis
angeschlossen wurden. Die durchschnittliche Schnitt-Naht-Zeit betrug 267±89 min,
bei einer durchschnittlichen Ischämiezeit von 86±20 min und Dauer der
arteriellen Anastomose von 29±12 min. In zwei Fällen erfolgte eine unmittelbar
intraoperative Anastomosenrevision, es trat jedoch kein einziger Lappenverlust
auf.
Schlussfolgerung Die Ergebnisse dieser Studie demonstrieren die sichere
Durchführbarkeit der robotisch-assistierten autologen Brustrekonstruktion
mittels kombinierter Anwendung des Symanis und des RoboticScopes. Zukünftig
sollte ein besonderes Augenmerkt auf minimalinvasive Techniken der Lappenhebung
und des Gefäßanschlusses gelegt werden.
