Enhanced Acoustic Emission in Relation to the Acoustic Halo Surrounding Active Region 11429

The use of acoustic holography in the high-frequency $p$-mode spectrum can resolve the source distributions of enhanced acoustic emissions within halo structures surrounding active regions. In doing so, statistical methods can then be applied to ascertain relationships with the magnetic field. This is the focus of this study. The mechanism responsible for the detected enhancement of acoustic sources around solar active regions has not yet been explained. Furthermore the relationship between the magnetic field and enhanced acoustic emission has not yet been comprehensively examined. We have used vector magnetograms from the \Helioseismic and Magnetic Imager (HMI) on-board the Solar Dynamics Observatory (SDO) to image the magnetic-field properties in the halo. We have studied the acoustic morphology of an active region, with a complex halo and "glories," and we have linked some acoustic properties to the magnetic-field configuration. In particular, we find that acoustic sources are significantly enhanced in regions of intermediate field strength with inclinations no different from the distributions found in the quiet Sun. Additionally we have identified a transition region between the active region and the halo, in which the acoustic source power is hindered by inclined fields of intermediate field strength. Finally, we have compared the results of acoustic emission maps, calculated from holography, and the commonly used local acoustic maps, finding that the two types of maps have similar properties with respect to the magnetic field but lack spatial correlation when examining the highest-powered regions.Comment: 19 pages, 8 figures, Accepted by Solar Physic

The importance of circulating tumor products as „liquid biopsies” in colorectal cancer

Liquid biopsies represent an array of plasma analysis tests that are studied to evaluate and identify circulating tumor products, especially circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA). Examining such biomarkers in the plasma of colorectal cancer patients has attracted attention due to its clinical significance in the treatment of malignant diseases. Given that tissue samples are sometimes challenging to procure or unsatisfactory for genomic profiling from patients with colorectal cancer, trustworthy biomarkers are mandatory for guiding treatment, monitoring therapeutic response, and detecting recurrence. This review considers the relevance of flowing tumor products like circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), circulating messenger RNA (mRNA), circulating micro RNA (miRNA), circulating exosomes, and tumor educated platelets (TEPs) for patients with colorectal cancer

Qualitative Assessment of the White Wine Varieties Grown in Dealu Bujorului Vineyard, Romania

Ecoclimatic conditions have a great influence on grapevine growth and development. Favourable conditions (solar radiation, temperature, humidity etc.) are important and have a positive effect on the growth and fruition. Critical conditions have negative influences resulting in low grape production and wine quality. The purpose of this research was to analyse the quality of wine obtained from eight grapevine varieties (four Romanian autochthonous varieties: ‘Feteasca regala’, ‘Feteasca alba’, ‘Babeasca gri’, ‘Sarba’, and four world-wide varieties: ‘Aligoté’, ‘Sauvignon Blanc’, ‘Muscat Ottonel’, and ‘Italian Riesling’). The wine samples were obtained from micro-wine production under local weather conditions of Dealu Bujoruluivineyard, Romania. The physico-chemical analysis of young wines showed that the highest alcohol content was recorded at the ‘Sauvignon blanc’ variety (14.35% vol.) followed by ‘Sarba’ (14.10% vol.). The highest level of acidity was registered to ‘Babeasca gri’ (5.90 g/L C4H6O6) and the lowest acidity in the ‘Muscat Ottonel’ wine (4.40 g/L C4H6O6). The pH values were between limits of 3.62 (‘Feteasca alba’) and 3.27 (‘Aligote’). In order to get a wider perspective about the wine quality, another 11 parameters were examined at these varieties, using spectrophotometric methods (acetic acid, potassium, calcium, free amino nitrogen, tartaric acid, copper, L-lactic acid, iron, L-malic acid, D-gluconic acid and glycerol). The results showed the suitability of ecoclimatic conditions and the proper growth and development of the tested varieties for obtaining wines withsuperiors quality

Some Additive Combinatorics Problems in Matrix Rings

We study the distribution of singular and unimodular matrices in sumsets in matrix rings over finite fields. We apply these results to estimate the largest prime divisor of the determinants in sumsets in matrix rings over the integers

Trends in Substance Use in a Prohibitionist University Compared to General College Populations

Researchers at the Institute for the Prevention of Addictions have conducted surveys on health risk behaviors among Andrews University students from 1995 to 2023. In examinations of five data points between 1995 and 2018, the gap in the rates of substance use between Andrews University students and a general U.S. college population remained about the same each time period. However, both groups tended to increase or decrease use over the same time periods. Data from the March 2023 collection period will be included in the presentation and will be examined to see if cultural levelling has occurred or if Andrews students have been able to resist the pull of cultural levelling

Health Beliefs, Behavior, Spiritual Growth, and Salvation in a Global Population of Seventh‑day Adventists

Background The Seventh-day Adventist Church is a growing global denomination with strict substance use abstinence and recommended dietary requirements that together are called the “Health Message.” Abstinence from alcohol and tobacco is a requirement of membership and a plant-based diet is strongly advised. Purpose While a wide variety of research has reported the Adventist health advantage, very little research has been conducted on Adventist members’ attitudes toward and adherence to the Health Message. This research examines members\u27 views, from a global survey, about the health message, personal adherence, and belief that adherence ensures salvation. Methods The survey was conducted in 2017/2018 with a total N of 63,756. The questionnaire was translated into about 60 languages and then back-translated into English for improved accuracy. Results Over 80% of the respondents reported that they agreed the Adventist health message was wholistic, core to Adventist beliefs, supported by science, and increased the probability of a longer life. There were very few differences by global regions. About 80% also agreed that they should abstain from tobacco and alcohol and follow a healthy diet. However, about 45% believed that they could pick and choose which parts to follow with only a little over one-third reporting that they followed the Health Message a great deal. Strict adherence appeared to be in abstinence from alcohol (91%) and tobacco (97%). Only about 19% reported being vegetarian or vegan. Over 47%, mostly in the Southern Hemisphere, reported the belief that if they kept the Health Message completely, they would be assured of salvation, though this is at odds with formal doctrine. Conclusions and Implications The data suggest that church leadership has been successful in obtaining global acceptance of the Health Message, convincing members of its scientific basis, and to abstain from tobacco and alcohol use. However, the data also show almost half of members believe that they can pick and choose elements to follow. In addition, these data have major implications for church leadership in disentangling the implications and expectations of the Health Message from the Church’s fundamental belief that salvation is only through faith in Christ

Quantum computation of stopping power for inertial fusion target design

Stopping power is the rate at which a material absorbs the kinetic energy of a charged particle passing through it -- one of many properties needed over a wide range of thermodynamic conditions in modeling inertial fusion implosions. First-principles stopping calculations are classically challenging because they involve the dynamics of large electronic systems far from equilibrium, with accuracies that are particularly difficult to constrain and assess in the warm-dense conditions preceding ignition. Here, we describe a protocol for using a fault-tolerant quantum computer to calculate stopping power from a first-quantized representation of the electrons and projectile. Our approach builds upon the electronic structure block encodings of Su et al. [PRX Quantum 2, 040332 2021], adapting and optimizing those algorithms to estimate observables of interest from the non-Born-Oppenheimer dynamics of multiple particle species at finite temperature. Ultimately, we report logical qubit requirements and leading-order Toffoli costs for computing the stopping power of various projectile/target combinations relevant to interpreting and designing inertial fusion experiments. We estimate that scientifically interesting and classically intractable stopping power calculations can be quantum simulated with roughly the same number of logical qubits and about one hundred times more Toffoli gates than is required for state-of-the-art quantum simulations of industrially relevant molecules such as FeMoCo or P450
