Context. An accurate 28P(p, γ)29S reaction rate is crucial to defining the nucleosynthesis products of explosive hydrogen burning in ONe novae. Using the recently released nuclear mass of 29S, together with a shell model and a direct capture calculation, we reanalyzed the 28P(p, γ)29S thermonuclear reaction rate and its astrophysical implication.
Aims. We focus on improving the astrophysical rate for 28P(p, γ)29S based on the newest nuclear mass data. Our goal is to explore the impact of the new rate and associated uncertainties on the nova nucleosynthesis.
Methods. We evaluated this reaction rate via the sum of the isolated resonance contribution instead of the previously used Hauser-Feshbach statistical model. The corresponding rate uncertainty at different energies was derived using a Monte Carlo method. Nova nucleosynthesis is computed with the 1D hydrodynamic code SHIVA.
Results. The contribution from the capture on the first excited state at 105.64 keV in 28P is taken into account for the first time. We find that the capture rate on the first excited state in28 P is up to more than 12 times larger than the ground-state capture rate in the temperature region of 2.5 × 107 K to 4 × 108 K, resulting in the total 28P(p, γ)29S reaction rate being enhanced by a factor of up to 1.4 at ~1 × 109 K. In addition, the rate uncertainty has been quantified for the first time. It is found that the new rate is smaller than the previous statistical model rates, but it still agrees with them within uncertainties for nova temperatures. The statistical model appears to be roughly valid for the rate estimation of this reaction in the nova nucleosynthesis scenario. Using the 1D hydrodynamic code SHIVA, we performed the nucleosynthesis calculations in a nova explosion to investigate the impact of the new rates of 28P(p, γ)29S. Our calculations show that the nova abundance pattern is only marginally affected if we use our new rates with respect to the same simulations but statistical model rates. Finally, the isotopes whose abundance is most influenced by the present 28P(p, γ)29S uncertainty are 28Si, 33,34S, 35,37Cl, and 36Ar, with relative abundance changes at the level of only 3% to 4%.

Context. Dwarf highly star-forming galaxies (SFGs) dominated the early Universe and are considered the main driver of its reionization. However, direct observations of these distant galaxies are mainly confined to rest-frame ultraviolet and visible light, limiting our understanding of their complete properties. Therefore, it is still paramount to study their local analogs, the green pea (GP) and blueberry (BB) galaxies.
Aims. This work aims to expand our knowledge of BBs by identifying a new sample that is closer and in the southern sky.
Methods. In addition to the already known BBs, this new sample will allow for a statistically significant study of their properties probed by visible and infrared (IR) light. By utilizing the HECATE catalog, which provides optical and IR photometry and characterization of galaxies, along with data from Pan-STARSS and SDSS, this study selects and analyzes a new sample of BBs. We employed spectral energy distribution fitting to derive homogeneous measurements of star-formation rates and stellar masses. Additionally, we measured emission-line fluxes, including He II λ4686, through spectral fitting.
Results. Through this work, we identified 48 BBs, of which 40 were first recognized as such, with the nearest at 19 Mpc. Fourteen of the BBs are in the south sky. The BBs tend to be extremely IR red in both WISE W1 – W2 and W2 – W3 colors, distinguishing them from typical SFGs. Dwarf SFGs with higher specific star-formation rates tend to have redder IR colors.
Conclusions. Blueberry galaxies stand out as the most intensely star-forming sources in the local Universe among dwarf galaxies. They are intrinsically bluer in visible light, redder in the infrared, and less massive. They also have higher specific star-formation rates, equivalent widths, lower metallicities, and the most strongly ionized interstellar medium compared to typical SFGs and GPs.

AbstractAdjuvant treatment of patients with early-stage breast cancer (BC) should include an aromatase inhibitor (AI). Especially patients with a high recurrence risk might benefit from an upfront therapy with an AI for a minimum of five years. Nevertheless, not much is known about the patient selection for this population in clinical practice. Therefore, this study analyzed the prognosis and patient characteristics of postmenopausal patients selected for a five-year upfront letrozole therapy.From 2009 to 2011, 3529 patients were enrolled into the adjuvant phase IV PreFace clinical trial (NCT01908556). Postmenopausal hormone receptor-positive BC patients, for whom an upfront five-year therapy with letrozole (2.5 mg/day) was indicated, were eligible. Disease-free survival (DFS), overall survival (OS) and safety in relation to patient and tumor characteristics were assessed.3297 patients started letrozole therapy. The majority of patients (n = 1639, 57%) completed the five-year treatment. 34.5% of patients continued with endocrine therapy after the mandated five-year endocrine treatment. Five-year DFS rates were 89% (95% CI: 88–90%) and five-year OS rates were 95% (95% CI: 94–96%). In subgroup analyses, DFS rates were 83%, 84% and 78% for patients with node-positive disease, G3 tumor grading, and pT3 tumors respectively. The main adverse events (any grade) were pain and hot flushes (66.8% and 18.3% of patients).The risk profile of postmenopausal BC patients selected for a five-year upfront letrozole therapy showed a moderate recurrence and death risk. However, in subgroups with unfavorable risk factors, prognosis warrants an improvement, which might be achieved with novel targeted therapies.

Published: May 2024

AbstractHistiocytic sarcoma (HS) is a rare malignancy with grave prognosis. Adult acute lymphoblastic leukemia (ALL) patients developing HS as a secondary malignancy reported in the literature is even rarer. Through our case report, we aim to describe an adult pre-B-ALL patient who subsequently developed extensive HS while on maintenance therapy. We present the course of the disease, the management, and the resultant outcome. Active reporting of the course and management of secondary HS in adult ALL patients need to be emphasized to gain better insight into the presentation and the course of the disease, incidence as well as molecular pathology, especially given the relative silence of the literature in this regard.
Modeling the audience’s perception of security in media discourse
Authors: Hu Chajuan 
Published: May 2024

AbstractCombining the concepts of securitization with a discourse analytic approach, the study presents an attempt to investigate how the audience’s perception toward an unconventional security issue has been shaped in media context. As a case study, this paper delves into the portrayal of the Confucius Institute in the U.S. media discourse. By analyzing the coverage of the Confucius Institute in The New York Times and The Wall Street Journal from 2004 to 2022, it aims to unpack the narratives and representations surrounding this institution. With a particular focus on how the use of language shapes the audience’s perception and subsequently influences their cognition in the context of the securitization of Confucius Institutes, a select sample of texts from the corpus was collected for coded qualitative analysis to allow for a deeper understanding of how the media constructs and disseminates information about the Confucius Institute. The findings turn out that American media actors deliver a bottom-up securitizing move by interacting with socio-political value positions on Confucius Institutes in the United States, grounding a cognitive construction of security threat into shaping public emotive perceptual experience with dialogically patterned linguistic configurations.
Similar but yet different: individual cognitive traits and family contingencies as antecedents of intrapreneurship and self-employment

AbstractEntrepreneurship is of great significance to individuals, families and society. Recently, intrapreneurship, i.e., business ventures within established organisations, has also attracted widespread interest among individuals and organisations. However, we still know little about how individuals make decisions when they face diverse types of entrepreneurial activities. Based on theories of entrepreneurial action and conservation of resources and the literature on family embeddedness, this paper proposes an integrated framework for entrepreneurial choice—including intrapreneurship, self-employment and non-entrepreneurship, and examines the roles of socio-cognitive traits and family contingency factors in the entrepreneurial choice process. By using secondary and survey data, the empirical results show that (a) entrepreneurial alertness (EA) and self-efficacy (ESE) both positively affect individuals’ choice towards intrapreneurship and self-employment, with a stronger effect on the latter; (b) the interaction between EA and ESE has a negative effect on intrapreneurship but a positive effect on self-employment; (c) family-to-work conflict weakens the aforementioned interactive effect on both intrapreneurship and self-employment, whereas work-to-family conflict strengthens its effect on self-employment; (d) household income strengthens the interactive effect on both intrapreneurship and self-employment. Overall, these findings contribute to a nuanced understanding of the relationship among individual cognitive traits, family contingencies and entrepreneurial choice. The theoretical and practical implications are discussed.
Pricing, assembly rate optimizations and coordination for prefabricated construction supply chain with government subsidies

Published: May 2024

AbstractPrefabricated construction, a sustainable construction method, has become the inevitable trend for the future development of the construction industry. The subsidy policies for prefabricated construction enterprises can influence their strategies to promote the development of prefabricated construction. The paper considers a two-echelon prefabricated construction supply chain consisting of a manufacturer and an assembler, aiming to investigate pricing and the assembly rate strategies and coordination under different subsidy objects. The findings demonstrate that subsidy policies can increase the assembly rate. When the government subsidizes the manufacturer, the wholesale price decreases with the subsidy rate, while subsidizing the assembler, the wholesale price does not change. The impacts of subsidy policies on the retail price depend on price sensitivity and the consumer preference for the prefabricated construction market. When the subsidy rates are equivalent, the profit of supply chain with subsidizing the assembler is greater than that with subsidizing the manufacturer. Finally, the paper proposes the revenue-cost sharing contract to coordinate prefabricated construction supply chain with government subsidies. A numerical study is carried out to verify conclusions, and illustrates that a certain range of subsidy affects positively prefabricated construction enterprises by adjusting the retail price and increasing the assembly rate.
Effects of listeners’ dialectal variation on comprehensibility and accentedness judgements of second language

Authors: Ghaffarvand-Mokari Payam 
Published: May 2024

Abstract
This study investigated the impact of listeners’ dialectal variations within the same L1 on perceptions of L2
speech comprehensibility and accentedness. Thirty untrained British and American English-L1 raters assessed recorded L2 speech
samples from 29 Finnish learners of English and provided scalar judgments for their comprehensibility and accentedness. Four
linguistically trained graduate students evaluated the samples for segmental accuracy, speech rate, word stress and intonation.
Results of linear mixed models indicated no significant effect of raters’ L1 variety on global comprehensibility and accentedness
ratings. While American and British raters relied on same pronunciation features in their comprehensibility judgments, they placed
different levels of importance on pronunciation features when making accentedness judgments. Particularly, both groups primarily
exhibited sensitivity towards segmental errors in their assessments of accentedness, whereas American raters demonstrated an
additional sensitivity to intonation. The findings underscore the complexity of accent perception based on the L1 variety of
listeners.

Abstract
Listen-and-repeat training has previously been successfully used to train the perception and production of
non-native vowel quality and duration contrasts. This study used a one-day listen-and-repeat training paradigm for the production
of a non-native vowel duration contrast, /tite – tiːte/ with no feedback or other instructions. Learning results were assessed by
acoustic analysis of the produced durations, and identification of the productions by listeners with quantity contrasts in their
native Finnish language. Training participants were 18 Namibian speakers of various Bantu and Khoe languages. The results showed
that the majority of the speakers did not produce a consistent acoustic duration contrast between the target words. In the
identification task, the listeners’ performance was at essentially chance level for almost all of the speakers. The results are
discussed in terms of earlier results using the same stimuli, training design and language background.

Comprehensive investigation into the influence of oxygen vacancies on the ferroelectric properties of spin coated bismuth ferrite thin films

Published: May 2024

Abstract
Bismuth ferrite (BFO) is a prime candidate for room-temperature magnetoelectric coupling and multiferroic applications. The rhombohedral R3c phase of BFO is the source of many properties, but the phase purity and oxygen vacancies are still the biggest obstacles to its real-world application. Considering these facts, the present work investigates the effects of oxygen vacancies on the functional properties through manipulation of drying temperatures of spin-cast films, especially at temperatures around 280 °C, where both the secondary phase and oxygen vacancies are prevalent. One of the biggest sources of oxygen vacancy is bismuth volatilisation, and our work deals with the situation head-on, uncovering the effect of bismuth volatilisation on functional properties. The structural properties were studied using x-ray diffraction (XRD), and deeper insights into the surface topography of the samples were obtained using AFM imaging. The electrical and dielectric characteristics help distinguish and analyse the samples in terms of the presence of resistive switching. PUND studies were performed to determine the ferroelectric properties of the samples. A fifty percent reduction in the oxygen vacancies in the presence of secondary phases was observed when compared with the phase-pure sample, as shown by the XPS analysis. Deeper insights were provided into the valence band spectra by first-principles studies. This work shows that phase purity may not be the singular condition for enhancing functional properties, and fine-tuning the presence of secondary phases and oxygen vacancies may be the way forward. The ferroelectric polarisation in one of the samples exhibits a notably higher value when using chemical solution deposition methods, making it a promising candidate for memory devices.

Published: May 2024

Abstract
The current study demonstrates the utilization of Raman spectroscopy, employing a laser system emitting @ 785 nm, and multivariate analysis for the accurate assessment of diabetes (glucose) in human blood sera. Raman spectra of sera samples collected from 40 patients of both genders of different age groups were acquired in the spectral range of 600–1800 cm−1. For comparison, the Raman spectra of non-diabetic healthy individuals were also obtained in the same spectral range. Apparent variations were found in normal and pathological samples at peak positions of 700 cm−1, 750 cm−1, 879 cm−1, 950 cm−1, band at 1004 cm−1 to 1006 cm−1, 1048 cm−1, 1060 cm−1, 1082 cm−1, 1091 cm−1, 1170 cm−1, 1247 cm−1, 1330 cm−1, 1333 cm−1, 1367 cm−1, 1659 cm−1 and 1745 cm−1. These variations are most likely due to variations in the concentration of amino-acid methionine, glycosylated, tryptophan, polysaccharides, phenylalanine, glycogen, glucose, carbohydrates, carbohydrates (C–O–H), tyrosine, guanine, typical phospholipids, guanine, phospholipid, cholesterol band, and triglycerides (fatty acids) respectively. For highlighting the spectral differences between the two data sets principal component analysis was used. The observed variations in Raman peaks provide an in-depth biochemical fingerprint of the samples and can be used as a biomarker for medical diagnosis effectively at the mass level.
Collectively induced transparency and absorption in waveguide quantum electrodynamics with Bragg atom arrays
Authors: Cheng Haolei , Nie Wei 
Published: May 2024

Abstract
Collective quantum states, such as subradiant and superradiant states, are useful for controlling optical responses in many-body quantum systems. In this work, we study novel collective quantum phenomena in waveguide-coupled Bragg atom arrays with inhomogeneous frequencies. For atoms without free-space dissipation, collectively induced transparency is produced by destructive quantum interference between subradiant and superradiant states. In a large Bragg atom array, multi-frequency photon transparency can be obtained by considering atoms with different frequencies. Interestingly, we find collectively induced absorption (CIA) by studying the influence of free-space dissipation on photon transport. Tunable atomic frequencies nontrivially modify decay rates of subradiant states. When the decay rate of a subradiant state equals to the free-space dissipation, photon absorption can reach a limit at a certain frequency. In other words, photon absorption is enhanced with low free-space dissipation, distinct from previous photon detection schemes. We also show multi-frequency CIA by properly adjusting atomic frequencies. Our work presents a way to manipulate collective quantum states and exotic optical properties in waveguide quantum electrodynamics (QED) systems.
