Spectroscopic imaging of biological tissue components by non-contact optical scanning based on the detection of ultrasound induced by mid-infrared laser radiation
Authors: Tanaka Nozomi , matsuura yuji 
Published: January 2025

Abstract
A biological spectral imaging system based on photoacoustic spectroscopy is proposed for real-time, in vivo measurements of biological samples. The system irradiates biological samples with mid-infrared laser light modulated at several hundred kilohertz and detects ultrasonic waves generated within the sample using a piezoelectric transducer. Spectral imaging results obtained using a bovine meat sample demonstrated that muscle and fat could be distinguished based on signal intensity at only two wavelengths, identified through support vector machine optimization. These findings enabled the imaging of porcine brain samples containing D-2-hydroxyglutarate, a tumor marker.

This study investigated EFL students’ speaking skills viewed from self-efficacy at seniors high schools. This to measure students' self-efficacy beliefs and assessments to evaluate their speaking performance to find factors influencing their speaking skills.. The findings of this study had the potential to provide valuable insights into the factors influencing students' speaking skills development and contribute to the enhancement of language learning and teaching practices, also to find whether there is a relationships between students' self-efficacy levels and their performance in speaking tasks. A quantitatave approach was employed by using SPSS IBM 26 and qualitative approach was employed by using observation and questionnaires, utilizing surveys, to measure students' self-efficacy beliefs and assessments to evaluate their speaking performance. The research included 30 second-grade Social Studies students from SMAN 7 Mataram, selected through purposive sampling. A questionnaire with two types of items, totaling 10 questions, was employed as the research tool. The major factors influencing students’ self efficacy at IPS class at SMAN 7 Mataram are social persuasion (50%) and Emotional & Physiological States (50%). The results indicated a strong relationships, with a Pearson correlation coefficient (R) of 0.895, which is considered very high, falling within the 0.80 to 1.000 range. The statistical analysis at a significance level of ? = 0.05 showed a p-value lower than 0.05 (0.000 < 0.05). Thus, the alternative hypothesis (H1) was accepted, and the null hypothesis (H0) was rejected, confirming a significant correlation between students’ self-efficacy and their speaking skills. It means that students need encouragement and support from parents, teachers, and their community to boost their self-efficacy to improve English speaking skills.

The production and consumption of organic rice in Indonesia continue to increase along with the growing public awareness of the importance of healthy eating habits and environmental conservation efforts. Consumers in Central Java and Yogyakarta increasingly favor organic rice, prioritizing health and product quality. This has led to increased demand and can also motivate farmers to increase organic rice production to meet the ever-growing market needs. This study analyzes the market dynamics and consumer preferences for organic rice in Central Java and Yogyakarta. The research employed a quantitative descriptive approach, utilizing the 4P marketing mix (product, price, place, promotion) and a Likert scale to measure consumer preferences. Sampling was conducted through proportional stratified random sampling from five regencies, with 310 respondents. The results show that promotion is the most significant factor influencing consumer purchasing decisions, with a relative importance of 30.289%. The primary factors driving consumer preferences for organic rice are health benefits and product quality. Although organic rice is priced higher than conventional rice, consumers tend to choose it due to its health and sustainability benefits. However, uneven distribution of organic rice and price fluctuations caused by high production costs and climate factors pose major challenges. The study suggests more intensive promotional strategies, improved market accessibility, and subsidy policies to support farmers’ production costs. By understanding market dynamics and consumer preferences, this research provides critical insights for stakeholders to design more effective policies and marketing strategies while supporting sustainable agriculture in Indonesia.

On the Age Calibration of Open Clusters Using Red Clump Stars

Published: January 2025

Abstract
In this study, we extend the dust-independent Hatzidimitriou relation between cluster age and d

B−R
color difference between the red giant branch (RGB) and red clump to younger cluster ages. We perform membership analysis on 14 galactic open clusters using Gaia DR3 astrometry, then compute the difference in color of the RGB and red clump d

B−R
using Gaia photometry. We also compute d

B−R
for five fields surrounding Small Magellanic Cloud clusters. We find that the trend derived from older clusters does not extrapolate to younger ages and becomes double valued. We confirm that d

B−R
is independent of metallicity. Current stellar evolutionary isochrones do not quantitatively reproduce the trend and furthermore predict an increased color gap with a decrease in metallicity that is not echoed in the data. Integrated light models based on current isochrones exaggerate the color change over the ​​​​​​−0.5 < [Fe/H] < 0 interval at the few-percent level.
Fitting Methods for Probability Distribution Functions in Turbulent Star-forming Clouds
Authors: Kiihne Avery , Appel Sabrina M. , Burkhart Blakesley , Semenov Vadim A. , Federrath Christoph 
Published: January 2025

Abstract
We use a suite of 3D simulations of star-forming molecular clouds, with and without stellar feedback and magnetic fields, to investigate the effectiveness of different fitting methods for volume and column density probability distribution functions (PDFs). The first method fits a piecewise lognormal and power-law (PL) function to recover PDF parameters such as the PL slope and transition density. The second method fits a polynomial spline function and examines the first and second derivatives of the spline to determine the PL slope and the functional transition density. The first PL (set by the transition between lognormal and PL function) can also be visualized in the derivatives directly. In general, the two methods produce fits that agree reasonably well for volume density but vary for column density, likely due to the increased statistical noise in the column density PDFs as compared to the volume density PDFs. We test a well-known conversion for estimating volume density PL slopes from column density slopes and find that the spline method produces a better match (χ
2 of 3.34 versus χ
2 of 5.92), albeit with a significant scatter. Ultimately, we recommend the use of both fitting methods on column density data to mitigate the effects of noise.
A Peculiar Feature of the First Ionization Potential Effect Before a Solar Flare Impulsive Phase Observed by MSS-1B, CHASE, and SDO
Authors: Ng Man-Hei , Zhang Xiaoping , Chen P. F. 
Published: January 2025

Abstract
The impulsive phase of solar flares is often accompanied by the depletion of the elements with low first ionization potential (FIP), whose abundance decreases from the coronal level to the photospheric level, and then recovers back to the coronal level during the decay phase. Recently, we analyzed the soft X-ray spectroscopic data of the 2024 February 16 flare event observed by the Macao Science Satellite-1B/Soft X-ray Detection Units. Surprisingly, however, it is revealed that the depletion of the low-FIP elements occurred well before the flare impulsive phase. The timing of this change provides important clues about the location of magnetic reconnection, shedding light on the mass and energy transfer between different layers of the solar atmosphere. By examining the multiwavelength data from the Solar Dynamics Observatory and CHASE missions, we found that there was no filament 0.4 hr before the flare eruption. However, an erupting filament was detected in association with the flare event. Based on these features, we propose for the first time that the flare/filament eruption for this event was initiated by magnetic reconnection in the solar chromosphere, rather than in the corona as stated in the standard flare model.
Einasto Profile as the Halo Model Solution Coupled to the Depletion Radius
Authors: Zhou Yifeng , Han Jiaxin 
Published: January 2025

Abstract
We constrain the halo profiles outside the halo boundaries by solving for the matching profiles required by the halo model. In the halo model framework, the matter distribution in the Universe can be decomposed into the spatial distribution of halos convolved with their internal structures. This leads to a set of linear equations in Fourier space that uniquely determines the matching halo profiles for any given halo catalog. In this work, we construct three halo catalogs with different boundary definitions and solve for the matching profiles in each case using measurements of halo–matter and halo–halo power spectra. Our results show that for a given halo field, there is always a set of matching profiles to accurately reconstruct the input statistics of the matter field, even though it might be complex to model the profiles analytically. Comparing the solutions from different halo catalogs, we find that their mass distributions inside the inner depletion radii are nearly identical, while they deviate from each other on larger scales, with a larger boundary resulting in a more extended profile. For the depletion-radius-based catalog, the numerical solution agrees well with the Einasto profile. Coupling the Einasto profile with the depletion catalog, the resulting halo model can simultaneously predict the halo–matter power spectra to 10% and the matter–matter power spectrum to 5%, improving over conventional models in both interpretability and versatility. The conditions and limitations of using the Navarro–Frenk–White profile in the halo model are also discussed.

Abstract
We present radiative transfer analyses of IRTF-TEXES and SOFIA-EXES mid-infrared spectra of Jupiter's mid- to high latitudes recorded between 2019 April 16 and 2023 July 20. The spectra were inverted across a photochemical model grid of varying eddy diffusion coefficient profiles, and the quality of fit of the synthetic spectra to the observed was used to constrain the CH4 homopause level. For a subset of latitudes/dates, we find that the CH4 homopause level is elevated in the region enclosed inside of, or magnetospherically poleward of, the northern ultraviolet main auroral emissions (MAEs) in comparison to the region outside or equatorward of the MAE. For example, using SOFIA-EXES results on 2021 June 10, we derived a CH4 homopause level of log(p

km above 1 bar poleward of the northern MAE at 68∘N compared to a lower limit of log(p
H) > 2.43 and upper limit of z
H < 322 km derived equatorward of the northern MAE. We therefore conclude that the region poleward of the northern MAE is, at times, subject to enhanced vertical transport resulting from auroral energy deposition. The exact mechanisms responsible for the enhanced vertical transport in Jupiter's auroral regions are uncertain: time-dependent circulation modeling of Jupiter's polar atmosphere is required to better understand this phenomenon. Poleward of the southern MAE, derived homopause levels agreed within uncertainty with those at equatorward locations. However, we consider this result a spatial sampling artifact rather than concluding that the southern auroral region is not subject to enhanced vertical transport.
Food security and dietary intake of a cohort of South African students during COVID-19
Authors: Jonker Juanita , Walsh Corinna 
Published: January 2025

Background: Food insecurity among students was a global concern even before the coronavirus disease 2019 (COVID-19) pandemic. Food security comprises having access to sufficient, safe and nutritious food at all times. The COVID-19 containment measures negatively influenced economies, impacting citizens’ food security.Aim: This study aimed to investigate the food security of a cohort of South African students during the COVID-19 pandemic.Setting: The sample included Health Science students from a university in Central South Africa.Methods: A mixed-method study was performed using questionnaires and focus group discussions. The questionnaire and focus group discussions investigated similar areas and were supported by literature. Ethical clearance was obtained.Results: Food insecurity existed among 84% of questionnaire participants. Dietary intake changed, with mainly a decrease in sugary and salty snacks. Focus group participants indicated an increase in the intake of starchy foods and reverted to binge eating. Dietary intake changes were attributed to poor availability and limited resources, for example money and electricity. Few participants were aware of or utilised available support services.Conclusion: The isolated, confined and extreme (ICE) environment that resulted from COVID-19 negatively impacted students’ dietary intake and food security. Institutions should implement measures to support students’ intake of healthy foods during ICE events.Contribution: This study provides significant insights into the dietary intake and food security of a cohort of Health Science students during COVID-19. It highlights the need for improved institutional and government food relief interventions during future pandemics. Therefore, this study contributes to the second sustainable development goal namely: zero hunger.
