BACKGROUND The mental well-being of individuals with coronary heart disease(CHD)during the intensive care unit(ICU)transition period is a multifaceted and significant concern.In this phase,the individuals might encounter psychological challenges like anxiety and depression,which can impede their recuperation and potentially have lasting effects on their health.AIM To investigate the correlation among psychological factors in CHD patients in the ICU transition period.METHODS A questionnaire survey was conducted with 119 patients admitted to the ICU after coronary artery bypass grafting between March and December 2023.Variations in Hamilton Anxiety Scale(HAMA)and Hamilton Depression Scale(HAMD),Fear of Progression Questionnaire-Short Form(Fop-Q-SF),and Social Support Rating Scale(SSRS)were collected and analyzed among diverse populations.We used Pearson’s correlation analysis to examine the correlation.Multiple linear regression analysis was used to explore whether these indicators influenced depression and anxiety in the patients.RESULTS The total scores for anxiety,depression,fear of disease progression,and social support were(7.50±1.41)points,(8.38±1.62)points,(35.19±8.14)points,and(36.34±7.08)points,respectively(P<0.05).Multivariate regression analysis showed that both the level of disease progression and social support affected the level of postoperative depression and anxiety in patients.CONCLUSION The anxiety and depression levels were positively related to each dimension of phobia disease progression and negatively related to each dimension of social support among patients with CHD. 展开更多

The Yb:YAG is an excellent high-average power and ultra-short pulse laser crystal. Transition intensity parameters A(tp)~k and Huang–Rhys factors are fitted to its emission spectrum by the full-profile fitting method. Calculated results indicate that the emission spectrum of Yb:YAG at cryogenic temperature consists of three pure electron state transitions and two phononassisted transitions, one vibronic transition releases one-phonon of 3 cm^(-1), and the other vibronic transition absorbs onephonon of 22 cm^(-1). At 300 K, the phonon assisted transition of 3 cm^(-1) turns into two-or more-phonon assisted transitions.The procedure absorbing phonon can reduce the thermal load of Yb:YAG and improve the laser efficiency, which may be one of the reasons why Yb:YAG has excellent performance. The emission bands of Yb:YAG are broadened thermally, and the peak values decrease by several times. The emission cross sections of Yb:YAG determined by Fuchtbauer–Ladenburg(F–L) formula are remarkably different from those calculated with A(tp)~k, which indicates that it is necessary for a laser material to determine its transition intensity parameters A(tp)~kin order to reasonably evaluate the laser performance. 展开更多

We show that in the quantum transition of an atom interacting with an intense laser of circular frequency ω, the energy difference between the initial and the final states of the atom is not necessarily an integer multiple of the quantum energy hω. This kind of non-integer transition is a true non-perturbation effect in laser-atom interaction. 展开更多

Quantum aspects of the Joule-Lenz law for the transmission of energy allowed us to calculate the time rate of energy transitions between the quantum states of the hydrogen atom in a fully non-probabilistic way. The calculation has been extended to all transitions between p and s states having main quantum numbers not exceeding 6. An evident similarity between the intensity pattern obtained from the Joule-Lenz law and the corresponding quantum-mechanical transition pro-babilities has been shown. 展开更多

The structure of the low-temperature 4f^N→4f^N-15d excitation spectra of Eu^3+ and Tb^3+ doped in crystals LiYF4, YPO4 and CaF2 measured by van Pieterson et al. in 2002 was analyzed and assigned based on the simple model proposed by Duan and co-workers in the last few years. Some complemental discussion on effects of J-mixing on the f-d transition intensities for Eu^3+ due to the f-electron crystal-field interaction Hcf(f), which was ignored in the simple mod- el, was presented. Some previously unexplained peaks for Tb^3 + were interpreted to be spin-forbidden transitions to higher 5d crystal-field levels, or assigned to be f→d excitations with the core 4f7 excited from ^8S to ^6P, ^6I and ^6D, respectively. It is shown that the main structure of 4f-Sd excitation spectra of Eu^3+ and Tb^3+ can be well interpreted with the simple model. 展开更多

We apply our sky map reconstruction method for transit type interferometers to the Tianlai cylin- der array. The method is based on spherical harmonic decomposition, and can be applied to a cylindrical array as well as dish arrays and we can compute the instrument response, synthesized beam, transfer func- tion and noise power spectrum. We consider cylinder arrays with feed spacing larger than half a wavelength and, as expected, we find that the arrays with regular spacing have grating lobes which produce spurious images in the reconstructed maps. We show that this problem can be overcome using arrays with a different feed spacing on each cylinder. We present the reconstructed maps, and study the performance in terms of noise power spectrum, transfer function and beams for both regular and irregular feed spacing configura- tions. 展开更多

The energy spectrum of the hydrogen atom has been applied in calculating the time rate of energy transitions between the quantum states of the atom. The formal basis of the approach has been provided by the quantum properties of energy and time deduced from the Joule-Lenz law. The rates of the energy transitions obtained in this way were compared with the quantum-mechanical probabilities of transitions calculated earlier by Bethe and Condon and Shortley for the same pairs of the quantum states. 展开更多
