Abstract： The study consists of two parts with a total of 190 children (95 sibling groups) participating in the experiment. The oldest sibling ranged in age from 7 years old to 4 years old. Younger siblings ranged in age from a maximum of 5 years old to a minimum of 3 years old. In Study 1, we coded and scored the initiating and responding behaviors during sibling interactions through the observation method, which mainly explored the interaction paths between sibling interactions at different points in time and the delineation of the sibling patterns under the processual perspective. In Study 2, we investigated the social development of the participating children, and further explored the effects of the processual sibling interaction pattern on the social development of the siblings. The findings of the study are summarized below:/t/nFirst, Sibling initiation and response behaviours were significantly positively correlated across time and sibling initiation behaviours at the same time significantly predicted each other’s response behaviours. Sibling initiating and responding behaviours were stable across time, and sibling responding behaviours significantly and positively predicted each other’s initiating behaviours at the next time, showing some lag effects./t/nSecond, Based on the intensive sibling interaction behaviour scores in the three times, the sibling interaction patterns can be classified into the friendly interaction pattern, i.e., the initiating and responding behaviours are positive in nature such as helping, praising, and soothing; the neutral sibling interaction pattern, i.e., the initiating and responding behaviours are reminders, verbal exchanges, and other behaviours that are not obviously positive or negative; and the confrontational sibling interaction pattern, i.e., the initiating and responding behaviours are negative in nature such as questioning, blaming, and scrambling./t/nThird, In sibling social development, both older and younger siblings showed significant sibling interaction pattern differences in emotional stability, peer relationships, nonaggression, empathy and helpfulness, and competitiveness and self-esteem. Younger siblings also showed significant sibling interaction pattern differences in observing social rules, living habits, self-concept, independence, and honesty and fairness./t/nThe main innovations of this study are that, firstly, it differs from most existing studies in that all siblings in the family are included in the study, so as to gain a more comprehensive and accurate understanding of the current status of sibling interaction and social development in the family. Secondly, this study uses the cross-lag model to analyse the path of interaction between initiating and responding behaviours in sibling interactions. The data are used to make the process of sibling interaction explicit, instead of just resting on textual descriptions or theories. Finally, this study does not use the traditional scoring method of overall interaction, but rather codes and scores each micro-process to capture the initiation and response of sibling interaction in real time, highlighting the processual character of sibling interaction.

Abstract： In this study, 14CH4, the largest proportion of 14C hydrocarbons and the most chemically stable, was taken as the treatment target, and a catalytic means was introduced to investigate the treatment performance of the non-equilibrium plasma catalytic oxidation of 14CH4 at very low concentration and the parameter influence law. The results showed that the Paxing breakdown voltage of the plasma generator in this study was 16.01 kV; the introduction of Pd/Al2O3 catalyst could significantly improve the CH4 treatment performance of the plasma, and by increasing the discharge voltage, decreasing the reaction temperature and the gas flow rate, the CH4 treatment efficiency and the CO2 selectivity could reach 100% and 83.7%; and there was a synergistic effect between the plasma and Pd/Al2O3 catalyst, and the Pd/Al2O3 catalyst had a synergistic effect. There is a synergistic effect, and Pd/Al2O3 can reduce the reaction barriers, optimize the reaction path, and significantly improve the CH4 treatment performance of the plasma, while the plasma-excited reactive species are also conducive to the generation of the key reactive phase PdO in the catalyst. The present results indicate that the plasma catalytic oxidation technology can realize the effective treatment of 14C hydrocarbons with very low concentration at room temperature and pressure, and has great potential for application.

Abstract： [Background] 223Ra SPECT/CT imaging was essential for evaluating the efficacy of bone metastasis therapy in metastatic castration-resistant prostate cancer (mCRPC). [Purpose] To explore the parameters of the Carlson model, the PET/CT model and Hoffman 3D brain model 223Ra SPECT/CT imaging. [Methods] In this study, GE NM/CT 670 ES quality control tests were performed on the Carlson model, the PET/CT model, and the Hoffman 3D brain model, and quality control standard images were acquired from the three models, and then 223Ra SPECT/CT imaging was examined for all three models, and the acquired images were compared with the quality control standard images. [Results] The results of the study showed that 223Ra SPECT/CT was capable of tomographic imaging. The 223Ra SPECT/CT images from the Carlson model with hot-area resolution (22.3 mm) and cold-area resolution (22.3 mm) were fair in linearity and homogeneity. The 223Ra SPECT/CT images from the PET/CT model were fair, whereas fusion matching degree and attenuation correction dispersion indexes of transverse, coronal, and sagittal images were a certain gap from the 99mTc SPECT/CT quality control images. The 223Ra SPECT/CT images in the Hoffman brain model showed that the intracerebral sulcus gyrus and basal ganglia nuclei were not clearly displayed, and it is necessary to continue to improve the image quality. [Conclusions] The study showed that the 223Ra SPECT/CT images were acceptable, which proved that the 223Ra SPECT/CT could be used to visualize clinical patients, but in order to obtain better quality images, the specific conditions of the visualization parameters need to be further explored.

Abstract： 469219 Kamo`oalewa is selected as one of the primary targets of Tianwen-2 mission, which is currently believed to be the most stable quasi-satellite of Earth. Here we derive a weak detection of the Yarkovsky effect for Kamo`oalewa, giving $A_2 = -1.075 pm0.447 times 10^{-13} rm{au/d}^2$, with the available ground-based optical observations from Minor Planet Center and a relatively conservative weighting scheme. Due to the quasi-satellite resonance with Earth, we show that the detection of Yarkovsky effect by orbital fitting with astrometric observations becomes difficult as its orbital drift shows a slow oscillatory growth resulting from the Yarkovsky effect. In addition, we extensively explore the characteristics of orbital uncertainty propagation and find that the positional uncertainty mainly arises from the geocentric radial direction in 2010-2020, and then concentrates in the heliocentric transverse direction in 2020-2030. Furthermore, the heliocentric transverse uncertainty is clearly monthly dependent, which can arrive at a minimum around January and a maximum around July as the orbit moves towards the leading and trailing edges, respectively, in 2025-2027. Finally, we investigate a long-term uncertainty propagation in the quasi-satellite regime, implying that the quasi-satellite resonance with Earth may play a crucial role in constraining the increase of uncertainty over time. Such interesting feature further implies that the orbital precision of Kamo`oalewa is relatively stable at its quasi-satellite phase, which may also be true for other quasi-satellites of Earth.

Abstract： The Closeby Habitable Exoplanet Survey (CHES) is dedicated to the astrometric exploration for habitable-zone Earth-like planets orbiting solar-type stars in close proximity, achieving unprecedented micro-arcsecond precision. Given the elevated precision, thorough consideration of photocenter jitters induced by stellar activity becomes imperative. This study endeavors to model the stellar activity of solar-type stars, compute astrometric noise, and delineate the detection limits of habitable planets within the astrometric domain. Simulations were conducted for identified primary targets of CHES, involving the generation of simulated observed data for astrometry and photometry, accounting for the impact of stellar activity. Estimation of activity levels in our samples was achieved through chromospheric activity indices, revealing that over 90% of stars exhibited photocenter jitters below 1 $ mu mathrm{as}$. Notably, certain proximate stars, such as $ alpha$ Cen A and B, displayed more discernible noise arising from stellar activity. Subsequent tests were performed to evaluate detection performance, unveiling that stellar activity tends to have a less pronounced impact on planetary detectability for the majority of stars. Approximately 95% of targets demonstrated a detection efficiency exceeding 80%. However, for several cold stars, e.g., HD 32450 and HD 21531, with the habitable zones close to the stars, a reduction in detection efficiency was observed. These findings offer invaluable insights into the intricate interplay between stellar activity and astrometric precision, significantly advancing our understanding in the search for habitable planets.

Abstract： The radionuclide air kerma rate constant Γa.Γa is a very important data in dose evaluation and shielding calculation, which requires the conversion coefficient of flux to air Kerma Ka/Φ and the information of nuclide decay photon. In 2020, the International Commission on Radiation and Measurements (ICRU) released Report 95 (Operational Quantities for External Radiation Exposure), which recommended a new Ka/Φ.[Purpose]: In order to verify the change in nuclide values after the basic data was updated.[Methods]: Based on the theory and Monte Carlo method, the air specific kinetic energy rate constants of 39 kinds of nuclides commonly used in medicine, industry and agriculture were calculated, and different interpolation methods and threshold selection were compared and analyzed.[Results and conclusions]: The cubic splines, logarithmic-logarithmic Lagrangian interpolation, and linear-logarithmic Lagrangian interpolation interpolation methods have little influence on the calculation of Γa. The calculation of Γa threshold selection pairs is very important, and the calculation of some nuclides with different thresholds is quite different, and the recommended nuclear medicine dose estimation is recommended to use a threshold of 10 keV, and the threshold of other cases is 20 keV. The difference between theoretical calculation and MCNP simulation calculation is small, and both can be used for constants calculation

Abstract： Complementary Metal Oxide Semiconductor (CMOS) image sensor is gradually replacing CCD image sensor with small size, light weight, low power consumption, high integration and other characteristics. In the space radiation environment, it has protons, heavy particles, gamma rays, A large number of high-energy particles such as electrons, CMOS image sensors will be subject to the radiation effect of heavy ions and have permanent damage to them.This paper focuses on the mechanism of permanent damage of CMV4000 under heavy ion irradiation. CMV4000 images after heavy ion irradiation have obvious hot pixels (the dark current peak is several times higher than the dark current peak of other pixels usually shows that the gray value of the pixel is several times higher than that of other normal pixels), and the hot pixels will not disappear in the next frame image and subsequent images, so the hot pixels are not temporary.This paper also considers the comparison of image parameters of CMOS image sensor before and after irradiation and reveals the degradation mechanism of each parameter.

Abstract： The Australia Telescope Large Area Survey (ATLAS) and the VLA survey in the XMM-LSS/VIDEO deep field provide deep ($\approx 15$ ${\mu}$Jybeam$^{-1}$) and high-resolution ($\approx$ 4.5--8 arcsec) radio coverage of the three XMM-SERVS fields (W-CDF-S, ELAIS-S1, and XMM-LSS). These data cover a total sky area of 11.3 deg$^2$ and contain $\approx 11000$ radio components. Furthermore, about 3~deg$^2$ of the XMM-LSS field also has deeper MIGHTEE data that achieve a median RMS of 5.6 ${\mu}$Jy beam$^{-1}$ and detect more than 20000 radio sources. We analyze all these radio data and find source counterparts at other wavebands utilizing deep optical and IR surveys. The nature of these radio sources is studied using radio-band properties (spectral slope and morphology), and the IR-radio correlation. %and spectral energy distribution. Radio AGNs are selected and compared with those selected using other methods (e.g. X-ray). We found 1656 new AGNs that were not selected using X-ray and/or MIR methods. We constrain the FIR-to-UV SEDs of radio AGNs using {\sc cigale} and investigate the dependence of radio AGN fraction upon galaxy stellar mass and star-formation rate.

Abstract： We present X-ray spectral and long-term variability analyses of an unbiased sample of 361 optically selected radio-loud quasars (RLQs) utilizing sensitive serendipitous X-ray data from the Chandra and XMM-Newton archives. The spectral and temporal properties of RLQs are compared with those of radio-quiet quasars (RQQs) matched in $L_\mathrm{2500A}$ and $z$. The median power-law photon index ($\Gamma$) of RLQs is $1.84^{+0.01}_{-0.01}$, which is close to that of matched RQQs ($1.90^{+0.02}_{-0.01}$). No significant correlations between $\Gamma$ and radio-loudness, $L_\mathrm{x}/L_\mathrm{x,rqq}$ (the X-ray luminosity over that expected from the $L_\mathrm{x}$-$L_\mathrm{uv}$ relation for RQQs), redshift, or Eddington ratio are found for our RLQs. The stacked X-ray spectra of our RLQs show strong iron-line emission and a possible Compton-reflection hump. The intrinsic X-ray variability amplitude is $\approx40$% for RLQs on timescales of months-to-years in the rest frame, which is somewhat smaller than for the matched RQQs ($\approx60$%) on similar timescales, perhaps due to the larger black-hole masses and lower Eddington ratios in our RLQ sample. The X-ray spectral and variability results for our RLQs generally support the idea that the X-ray emission of typical RLQs is dominated by the disk/corona, as is also indicated by a recent luminosity correlation study.

Abstract： Radio-loud quasars (RLQs) are known to produce excess X-ray emission, compared to radio-quiet quasars (RQQs) of the same luminosity, commonly attributed to jet-related emission. Recently, we found that the HeII EW and $\alpha_{\rm{ox}}$ in RQQs are strongly correlated, which suggests that their extreme-ultraviolet (EUV) and X-ray emission mechanisms are tightly related. Using 48 RLQs, we show that steep-spectrum radio quasars (SSRQs) and low radio-luminosity ($L_{\rm R}$) flat-spectrum radio quasars (FSRQs) follow the $\alpha_{\rm ox}$--HeII EW relation of RQQs. This suggests that the X-ray and EUV emission mechanisms in these types of RLQs is the same as in RQQs, and is not jet related. High-$L_{\rm R}$ FSRQs show excess X-ray emission given their HeII EW by a factor of $\approx$ 3.5, which suggests that only in this type of RLQ is the X-ray production likely jet related.

Abstract： Radio-loud quasars (RLQs) are more X-ray luminous than predicted by the X-ray-optical/UV relation (i.e. $L_\mathrm{x}\propto L_\mathrm{uv}^\gamma$) for radio-quiet quasars (RQQs). The excess X-ray emission depends on the radio-loudness parameter ($R$) and radio spectral slope ($\alpha_\mathrm{r}$). We construct a uniform sample of 729 optically selected RLQs with high fractions of X-ray detections and $\alpha_\mathrm{r}$ measurements.We find that steep-spectrum radio quasars (SSRQs; $\alpha_\mathrm{r}\le-0.5$) follow a quantitatively similar $L_\mathrm{x}\propto L_\mathrm{uv}^\gamma$ relation as that for RQQs, suggesting a common coronal origin for the X-ray emission of both SSRQs and RQQs. However, the corresponding intercept of SSRQs is larger than that for RQQs and increases with $R$, suggesting a connection between the radio jets and the configuration of the accretion flow. Flat-spectrum radio quasars (FSRQs; $\alpha_\mathrm{r}>-0.5$) are generally more X-ray luminous than SSRQs at given $L_\mathrm{uv}$ and $R$, likely involving more physical processes. The emergent picture is different from that commonly assumed where the excess X-ray emission of RLQs is attributed to the jets. We thus perform model selection to comparecritically these different interpretations, which prefers the coronal scenario with a corona-jet connection. A distinct jet component is likely important for only a small portion of FSRQs.The corona-jet, disk-corona, and disk-jet connections of RLQs are likely driven by independent physical processes. Furthermore, the corona-jet connection implies that small-scale processesin the vicinity of SMBHs, probably associated with the magnetic flux/topology instead of black-hole spin, are controlling the radio-loudness of quasars.

Abstract： We have investigated the jet-linked \mbox{X-ray} emission from highly radio-loud quasars (HRLQs; $\log R>2.5$) at high redshift. We studied the X-ray properties of 15 HRLQs at $z>4$, using new {\it Chandra} observations for six objects and archival {\it XMM-Newton} and {\it Swift} observations for the other nine. We focused on testing the apparent enhancement of jet-linked \mbox{X-ray} emission from HRLQs at $z>4$. Utilizing an enlarged (24 objects) optically flux-limited sample with complete X-ray coverage, we confirmed that HRLQs at $z>4$ have enhanced X-ray emission relative to that of HRLQs at $z\approx$ 1--2 with matched UV/optical and radio luminosity, at a \mbox{4.0--4.6}~$\sigma$ level; the X-ray enhancements are confirmed considering both two-point spectral indices and inspection of broad-band spectral energy distributions. The typical factor of enhancement is revised to $1.9^{+0.5}_{-0.4}$, which is smaller than but consistent with previous results. A fractional IC/CMB model can still explain our results at high redshift, which puts tighter constraints on the fraction of IC/CMB X-rays at lower redshifts, assuming the physical properties of quasar jets do not have a strong redshift dependence. A dominant IC/CMB model is inconsistent with our data.

Abstract： Rapid flares from blazars in very high energy (VHE) $\gamma$-rays challenge the common understanding of jets of active galactic nuclei (AGNs). The same population of ultra-relativistic electrons is often thought to be responsible for both X-ray and VHE emission. We thus systematically searched for X-ray flares at sub-hour timescales of TeV blazars in the entire Rossi X-ray Timing Explorer archival database. We found rapid flares from PKS 2005-489 and S5 0716+714, and a candidate rapid flare from 1ES 1101-232. In particular, the characteristic rise timescale of PKS 2005-489 is less than half a minute, which, to our knowledge, is the shortest among known AGN flares at any wavelengths. The timescales of these rapid flares indicate that the size of the central supermassive black hole is not a hard lower limit on the physical size of the emission region of the flare. PKS 2005-489 shows possible hard lags in its flare, which could be attributed to particle acceleration (injection), its flaring component has the hardest spectrum when it first appears. For all flares, the flaring components show similar hard spectra with $\Gamma=1.7-1.9$, and we estimate the magnetic field strength $B\sim$ 0.1--1.0 G by assuming synchrotron cooling. These flares could be caused by inhomogeneity of the jets. Models that can only produce rapid $\gamma$-ray flares but little synchrotron activity are less favorable.

Abstract： Fluxes emitted at different wavebands from active galactic nuclei (AGNs) fluctuate at both long and short timescales. The variation can typically be characterized by a broadband power spectrum, which exhibits a red-noise process at high frequencies. The standard method of estimating power spectral density (PSD) of AGN variability is easily affected by systematic biases such as red-noise leakage and aliasing, in particular, when the observation spans a relatively short period and is gapped. Focusing on the high-frequency PSD that is strongly distorted due to red-noise leakage and usually not significantly affected by aliasing, we develop a novel and observable normalized leakage spectrum (NLS), which describes sensitively the effects of leaked red-noise power on the PSD at different temporal frequencies. Using Monte Carlo simulations, we demonstrate how an AGN underlying PSD sensitively determines the NLS when there is severe red-noise leakage and thereby how the NLS can be used to effectively constrain the underlying PSD.
