Abstract： This study delves into a case of post-cesarean abdominal distension, exploring the comprehensive treatment effects and corresponding nursing methods of combining Traditional Chinese Medicine (TCM) acupressure with Neostigmine acupoint injection. In this case, we successfully employed TCM acupressure techniques along with Neostigmine injections at key acupoints such as Zusanli, Shangjuxu, and Xiajuxu, providing precise stimulation. This integrative treatment approach significantly enhanced gastrointestinal motility and regulated the body’s internal Qi, thereby alleviating the symptoms of postoperative abdominal distension. Additionally, our approach incorporated emotional care and pain management, holistically improving the patient’s quality of life. The results of this study not only confirm the unique advantages of combining traditional Chinese and Western medicine in managing postoperative complications but also offer new insights and methodologies for future clinical nursing practices.

Abstract： Small modular reactors have received widespread attention owing to their inherent safety, low investment, and flexibility. Small pressurized water reactors (SPWRs) have become important candidates for SMRs owing to their high technological maturity. Since the Fukushima accident, research on accident-tolerant fuels (ATFs), which are more resistant to serious accidents than conventional fuels, has gradually increased. This study analyzes the neutronics and thermal hydraulics of an SPWR (ACPR50S) for different ATFs, BeO+UO2-SiC, BeO+UO2-FeCrAl, U3Si2-SiC, and U3Si2-FeCrAl, based on a PWR fuel-management code, the Bamboo-C deterministic code. In the steady state, the burnup calculations, reactivity coefficients, power and temperature distributions, and control-rod reactivity worth were studied. The transients of the control-rod ejection accident for the two control rods with the maximum and minimum reactivity worth were analyzed. The results showed that 5% B-10 enrichment in the wet annular burnable absorbers assembly can effectively reduce the initial reactivity and end-of-life reactivity penalty. The BeO+UO2 -SiC core exhibited superior neutronic characteristics in terms of burnup and negative temperature reactivity compared with the other three cases owing to the strong moderation ability of BeO+UO2 and low neutron absorption of SiC. However, the U3Si2 core had a marginally better power-flattening effect than BeO+UO2, and the differential worth of each control-rod group was similar between different ATFs. During the transient of a control-rod ejection, the changes in the fuel temperature, coolant temperature, and coolant density were similar. The maximum difference was less than 10◦C for the fuel temperature and 2 ◦ C for the coolant temperature.

Abstract： ［ Purposes］This study aims to explore the dynamic trend of the number of journal papers and impact factors in the past five years from different dimensions and investigate the impact of the increase of the paper quantity on impact factors and the Journal Citation Indicator (JCI). ［Methods］From the Web of Science (WoS) database, 8094 journals continuously indexed by Science Citation Index (SCI) from 2018—2022 were chosen as the research subjects. We conducted statistical analysis and comparison of the paper quantity and impact factors across these five years. Furthermore, we analyzed the relationship among the paper quantity, impact factors, and JCI across the five years.［ Findings］The total quantity of papers published annually is on the rise, while the number of journals that primarily experience an increase in paper quantity is less than that with a decrease. The overall trend for the annual average impact factors is upward, with a significantly higher number of journals reporting an increase in impact factors compared to those with a decrease. In various countries and regions and across different disciplines, the greatest increase in both the paper quantity and impact factors occurred in 2020, with the first decline observed in 2022 over the past five years. China’s journals have consistently shown robust growth in both paper quantity and impact factors. Among journals with increased paper quantity, there are more journals with an increase in impact factors than those with a decrease, but the situation is reversed for the JCI. The increase in journal paper quantity does not have a statistically significant correlation with changes in impact factors and JCI (P>0.05).［Conclusions］The variations in the annual total paper quantity are markedly inconsistent with the changes in the paper quantity across individual journals. The annual increase in the impact factors shows a high degree of consistency with the year-on-year changes in the JIF of each journal. In recent years, there has been a steady enhancement in both the quantity and quality of papers published in China’s SCI journals. There is no correlation between the paper quantity and the JIF, and the attempt to raise the JIF by reducing the paper quantity lacks scientific
validity.

Abstract： X-ray detectors show potential applications in medical imaging, materials science, and nuclear energy. To achieve high detection efficiency and spatial resolution, many conventional semiconductor materials, such as amorphous selenium, cadmium telluride zinc, and perovskites have been utilized in direct conversion X-ray detectors. However, these semiconductor materials are susceptible to temperature-induced performance degra-dation, crystallization, delamination, uneven lattice growth, radiation damage, and high dark current. This study explores a new approach by coupling an FC40 electronic fluorinated liquid with a specialized high-resolution and high-readout-speed complementary metal-oxide-semiconductor (CMOS) pixel array, specifically the Top-metal II− chip, to fabricate a direct conversion X-ray detector. The fluorinated liquid FC40 (molecular formula: C21F48N2) is an electronic medium that is minimally affected by temperature and displays no issues with uniform conductivity. It exhibits a low dark current and minimal radiation damage and enables customizable thickness in X-ray absorption. This addresses the limitations inherent in conventional semiconductor-based de-tectors. In this study, simple X-ray detector imaging tests were conducted, demonstrating the excellent coupling capability between FC40 electronic fluorinated liquid and CMOS chips by the X-ray detector. A spatial reso-lution of 4.0 lp/mm was measured using a striped line par card, and a relatively clear image of a cockroach was displayed in the digital radiography imaging results. Preliminary test results indicated the feasibility of fabricating an X-ray detector by combining FC40 electronic fluorinated liquid and CMOS chips. Owing to the absence of issues related to chip-material coupling, a high spatial resolution could be achieved by reducing the chip pixel size. This method presents a new avenue for studies on novel liquid-based direct conversion X-ray detectors.

Abstract： [Background]: Neutron capture reaction cross sections are of significant importance in various fields, including fundamental physics, nuclear astrophysics, nuclear engineering, and materials science. Traditionally, the measurement of neutron capture reaction cross sections involves detecting all gamma rays produced from the target nucleus after reacting with neutrons. Theoretical methods are then used to calculate the proportion of the neutron capture reaction, thus obtaining the cross section. This method relies heavily on theoretical predictions and the combined effects of multiple reaction channels, which can obscure the structural features of the target reaction, resulting in smoothed cross section data in the resonance regions predicted by theory. [Purpose]: To overcome the limitations of the traditional method and reduce dependency on theoretical predictions, a more precise method utilizing high-energy resolution gamma detectors is needed to accurately measure the neutron capture reaction cross sections by identifying the yields of individual reaction channels. [Methods]: By analyzing the decay scheme of reaction products, high-energy resolution gamma detectors were employed to measure one or more characteristic gamma lines that can represent the reaction effects. This approach excludes interference from other reaction channels, thereby providing accurate neutron capture reaction cross sections. The 91Zr(n,γ)92Zr reaction was used to compare the advantages and disadvantages of this method with the traditional method. The experiment was conducted at the China Spallation Neutron Source. [Results]: In this work, clear resonance phenomena was observed in the theoretically predicted resonance regions. The results in non-resonance regions were consistent with previous data within error margins. This demonstrates that the new method provides accurate and reliable data for neutron capture reaction cross sections. [Conclusions]: The proposed method has significant advantages over traditional methods, offering a new approach for measuring neutron capture reaction cross sections. It reduces reliance on theoretical predictions and provides more detailed and accurate cross section data, especially in the resonance regions. This new method offers a promising direction for future research in neutron capture reactions.

Abstract： [Background]: With the continuous development of nuclear technology, the demand for radiation protection is increasing, and the optimization research of protective materials is receiving more and more attention. [Purpose]: Develop lightweight, lead-free flexible X-ray protective materials for commonly used medical diagnostic X-ray tubes within the voltage range of 150 kV. [Methods]: Firstly, focusing on studying the X-ray energy spectrum characteristics under 80, 100, and 120 kV tube voltages, and analyzing their bremsstrahlung and characteristic radiation characteristics; Secondly, using the Xcom program to calculate the photon absorption cross-sections of different elements and using the MCNP program to simulate and predict shielding performance; Finally, the shielding performance of the flexible X-ray protection material prepared is tested and verified by experiments. [Results]: The W+Bi based composite material combined with Gd has excellent shielding performance, with a highest shielding efficiency of 82.98% at 120 kV tube voltage, a mass attenuation coefficient of 6.47 cm2·g-1, a linear attenuation coefficient of 10.12 cm-1, and a half value layer of 0.07 cm. [Conclusions]: Theoretical prediction indicates that the absorption cross section tends to decay with energy, but there is a significant K-absorption edge effect in the low-energy region. Not only W, Bi, and Gd elements all have high mass absorption coefficients for X-rays, but also thier K-absorption edges have complementary advantages, which can effectively shield both bremsstrahlung and characteristic radiation in the energy spectrum. This study can deepen our understanding of medical X-ray shielding strategies and provide guidance for the development of lightweight, lead-free flexible X-ray protective materials.

Abstract： In conventional isochronous mass spectrometry (IMS) performed at a storage ring, the precision of mass measurement for short-lived nuclei depends on the precise determination of the revolution times (Ts) of stored ions. However, the resolution of T inevitably deteriorates due to the magnetic rigidity spread of the ions, resulting in limited mass resolving power. In this work, we measure the betatron tune Q (the number of betatron oscillations within a single revolution) of the ions, and construct a correlation between T and Q. From this correlation, the T are transformed corresponding to a fixed Q with higher resolution. Using the transformed Ts, we re-determine the masses of 63Ge, 65As, 67Se, and 71Kr, which agree well with the mass values measured by the newly developed IMS (Bρ-IMS). We also study the systematics of Coulomb displacement energies (CDEs) and find that the anomalous staggering in CDEs is removed using the new mass values. This method of T transformation is very useful for the conventional IMS equipped with a single time-of-flight detector.

Abstract： [Background]: In ESR dating of old fossils, the Double Saturation Exponential (DSE) function is often used for the equivalent dose (DE) determination, it generally requires more than 15 dose points and the maximum irradiation dose (Dmax) of ＞20kGy to ensure the fitting accuracy, which limit the practical application of dating old fossils by ESR method with insufficient sample size. [Purpose]: This study attempts to explore the feasibility and reliability of using the single saturation exponential (SSE) fitting function to fit fewer dose points with lower Dmax to obtain the DE values of the fossil teeth from pre-Early Pleistocene sites, and compared with the ones determined by DSE function of 17 fossil samples from the late Miocene to the early Pleistocene. [Methods]: First, we compared the DE values obtained by three fitting functions (DSE, SSE and EPL-exponential plus linear) by the additional dose method. Then, the influence of different Dmax on the DE results is investigated. Finally, the artificially regenerative dose-response curves fitted by the three functions with the weighted mean ESR signal intensity of the dose points were compared. [Results]: This study showed that (1) the DE results of SSE and EPL functions are systematically higher than those of DSE function under the same condition as Dmax=50kGy and 15 dose points, and the fitting accuracy of former two functions is better than that of DSE function in general. (2) For samples with DE＞4500Gy and DE＜4500Gy, the results of SSE and DSE are basically consistent within the error range under the conditions of Dmax≥6.5*DE and 1.3*DE＜Dmax＜2.2*DE, respectively, which can provide the recommended dose value of Dmax for samples with DE＞2000Gy when using SSE function. (3) For fossil samples with DE＜4500Gy, the SSE function can be used to fit the 11 dose points with Dmax≤10kGy, and the DE results are generally consistent with the DSE function within the error range. (4) The artificially regenerative dose-response curves of the weighted mean ESR signal intensity of the sample dose points showed that the DSE function had the best goodness of fit at 15 dose points, and the goodness of fit between the SSE and DSE function tended to be close at 11 dose points. [Conclusions]: Based on our study, it is viable to use SSE function to perform DE fitting on old fossil samples under certain Dmax/DE conditions. In the further study, we will try the fragmental analysis of the fossil teeth for DE determination and to establish the standard growth curve of old fossils established by the DE values obtained by SSE and DSE functions and compared with conventional additive dose method to explore its feasibility.

Abstract： Owing to the Thomson scattering between relativistic electrons and a laser, continuously polarization-tunable X-rays can be easily generated, providing an excellent probe for advanced X-ray imaging. In this paper, a method for simultaneous fluorescence and Compton scattering computed tomography is proposed using linearly polarized X-rays. The proposed method feasibility was verified using Monte Carlo simulations. In the simulations, the phantom is a polytetrafluoroethylene (Teflon) cylinder inside which are cylindrical columns containing aluminum, water, and gold (Au)-loaded water solutions with Au concentrations ranging between 0.5--4.0 wt%, and a parallel hole collimator imaging geometry was adopted. By adjusting the incident X-ray polarization direction, both the X-ray fluorescence computed tomography (XFCT) and Compton scattering computed tomography (CSCT) images of the phantom were accurately reconstructed using a maximum-likelihood expectation maximization algorithm. A similar attenuation contrast problem for the different cylindrical columns in the phantom can be resolved in the XFCT and CSCT images. The interplay between XFCT and CSCT was analyzed and the contrast-to-noise ratio (CNR) of the reconstruction was improved by correcting for the mutual influence between the two imaging modalities. Compared with K-edge subtraction imaging, XFCT exhibits a CNR advantage for the phantom.

Abstract： The accessibility and quality of ambulatory care（including outpatient and emergency services in primary care facilities，hospitals and other healthcare facilities） determine the efficiency of overall health care system and population health. Ambulatory care is also the core component of continuing care in an aging society. The concept of ambulatory care sensitive conditions（ACSCs） was firstly introduced by American researchers in 1990s. Since then，hospitalization for ambulatory care sensitive conditions（ACSHs） was widely used to evaluate the accessibility and quality of ambulatory care. In recent years， research on ACSH has gradually attracted the attention of scholars from all over the world，and preliminary research evidence from China indicated that the issue should not be ignored. This paper firstly introduces the origin of the concept of ACSH，then identifies the mixing concepts such as ACSH，avoidable hospitalization and inappropriate hospital admission，systematically summarizes the cutting-edge international identification criteria of ACSH，and finally discusses the policy value of ACSH as an indicator in the context of domestic and international research advances，clarifies the problems that should be noted in the identification of ACSCs in China，proposes strategies to reduce ACSH.

Abstract： Psychological and brain science study human behavior and the human brain by study volunteers who participate these studies. Given the mind and behavior of participants influenced by their own biological and social factors, the generalizability of findings in these fields largely depends on the representativeness of samples. However, the representativeness of samples in psychological and brain science has long been criticized as WEIRD (Western, Educated, Industrialized, Rich, and Democratic). In recent years, several meta-researches have surveyed the representativeness of samples in published studies across different subfields, but the overall understanding of sample representativeness in psychological and brain science is lacking. In this review, we analyze these meta-researches to provide a more comprehensive perspective on the current state of sample representativeness in the field.
Two major issues were found in these meta-researches. First, much important sample information was never reported in the published studies. Most psychological and brain science studies reported participants’ gender, age, and country, while participants’ race/ethnicity, education level, and socioeconomic status were less commonly reported. Other important demographic variables, such as rural/urban, were reported completely ignored. And from a temporal perspective, the reporting of these demographic variables has increased only slightly in recent years compared to the past. The current situation of neglect in reporting demographic information has not fundamentally changed.
Second, based on the reported information, the current sample in the field is far from being representative of the world population: most participants are young, highly educated Caucasian females in Western countries; middle-aged and older, less educated, disadvantaged people in and outside Western countries are less likely to be studied. In terms of countries, African, Latin American, and Middle Eastern countries appear fewer in psychological and brain science research.
These two issues may be due to the following reasons: convenience sampling as the main sampling method; Western researchers dominating the research of psychology and brain science, with most of the editors-in-chief, editorial board members, and authors coming from Europe and America; traditionally, psychology and brain science under-valued the effect of culture and various demographic factors; the assumption that findings from Western participants can be generalized to all human beings. Addressing the issue of sample representativeness in psychological and brain sciences requires a concerted effort by researchers, academic societies, journals, and funding agencies: Researchers should collect and report detailed demographic information about participants, state the limitations of generalizability, and use sampling methods that can increase representativeness whenever possible (e.g., probability sampling); academic societies should raise the awareness of the representativeness issues by organizing more academic symposium or workshops on this topic; journals should increase the representativeness of editorial board members and encourage more rigorous research with samples from underrepresented groups or studies that examine the generalizability of important findings; funding agencies can encourage researchers to pay more attention to study groups from underrepresented countries, and provide financial support for studying hard-to-research population. Improving sample representativeness will enhance the application of psychological and brain science knowledge to real-life setting and promote the building of a community with a shared future for mankind.

Abstract： The impact of the radiation dose produced by 222Rn/220Rn and its progeny on human health has garnered
increasing interest in the nuclear research field. The establishment of robust, regulatory, and competent 220Rn
chambers is crucial for accurately measuring radioactivity levels. However, studying the uniformity of the 220Rn
progeny through experimental methods is challenging, because measuring the concentration of 220Rn and its
progeny in multiple spatial locations simultaneously and in real time using experimental methods is difficult.
Therefore, achieving precise control of the concentration of 220Rn and its progeny as well as the reliable sampling
of the progeny pose significant challenges. To solve this problem, this study uses computational fluid dynamics
to obtain the flow-field data of the 220Rn chamber under different wind speeds and progeny-replenishment rates.
Qualitative analysis of the concentration distribution of the progeny and quantitative analysis of the progeny
concentration and uniformity of the progeny concentration are conducted. The research findings indicated
that the progeny-concentration level is primarily influenced by wind speed and the progeny-complement rate.
Wind speed also plays a crucial role in determining progeny-concentration uniformity, whereas the progeny-
complement rate has minimal impact on uniformity. To ensure the accuracy of 220Rn progeny-concentration
sampling, we propose a methodology for selecting an appropriate sampling area based on varying progeny
concentrations. This study holds immense importance for enhancing the regulation and measurement standards
of 220Rn and its progeny.

Abstract： [Background] As a typical representative of passive safety technology, the automatic depressurization system ( ADS ) accelerates the reactor primary loop depressurization after the accident, connects the high-pressure, medium-pressure and low-pressure safety injection systems, and maintains the core cooling. [Purpose] In order to study the opening and closing characteristics of the pressure relief valve of the automatic depressurization system and its influence on the reactor systems. [Methods] Based on the system analysis program, China Advanced Pressurized Water Reactor is taken as the research object, and the typical ADS trigger accident is taken as the initial event. The different opening speeds of the first three valves of ADS and the closing conditions of the fourth pressure relief valve of ADS are simulated, and the response of each system under different working conditions is analyzed. [Results] The results show that, the opening speed of the ADS1-3 valve cannot significantly affect the pressure relief characteristics of the primary loop; the ADS-1 pressure relief valve uses a quick opening method which helps the sprinkler reach the stable critical jet state faster; the ADS-2/3 pressure relief valve uses a slow opening method which is helpful to avoid "sharp" peak points in the pipeline flow curve and reduce the impact of the spraying process on the pipeline and sprinklers while satisfying the economic principle; ADS-4 is crucial for small break LOCA accident and also necessary for the injection of pressure tank at the later stage of the accident. [Conclusions] Through the simulation analysis of the opening and closing characteristics of the ADS pressure relief valve, it provides a reference for the design of the automatic depressurization system, and also provides theoretical and data support for the safety analysis of advanced nuclear power plants.
