This study explores the clinical efficacy of budesonide combined with ambroxol inhalation therapy for neonatal pneumonia.A total of 68 neonatal pneumonia patients treated at Li County Hospital from January 2023 to December 2024 were randomly divided into a monotherapy group and a combination group,with 34 patients in each.The monotherapy group received ambroxol inhalation therapy,while the combination group received budesonide inhalation therapy in addition to ambroxol.The recovery progress,blood gas analysis indicators,inflammatory response improvement,and overall clinical efficacy were compared between the two groups.Results showed that the combination group experienced a significantly shorter time for body temperature normalization(3.36±0.58 days vs.4.59±0.45 days),oxygen inhalation duration(4.89±0.57min vs.6.96±0.79min),disappearance of shortness of breath and cough(4.56±0.29 days vs.6.63±0.75 days),and resolution of lung wet rales(5.62±1.46 days vs.7.92±1.28 days)compared to the monotherapy group(P<0.05).Additionally,the total effective rate was significantly higher in the combination group(97.06%)than in the monotherapy group(73.52%)(P<0.05).Post-treatment,the combination group exhibited significantly better blood gas analysis and inflammatory response indicators(P<0.05).These findings suggest that budesonide combined with ambroxol inhalation therapy can effectively improve blood oxygen saturation,reduce inflammation,promote faster recovery,and enhance overall clinical efficacy,making it a reliable treatment option for neonatal pneumonia. 展开更多

Characteristics of the main shock and aftershocks of the Dingri M_(S)6.8 earthquake in the Xizang Autonomous region were determined by the double-difference location method using phase reports from Jan. 7 to Jan. 16, 2025. We find that the aftershocks were generally distributed in a near NS direction along the Dengmoduo fault, with a long axis of about 70 km. There is an obvious seismic gap to the north side of the main shock, which is consistent with the location of the maximum rupture point as revealed by surface survey of the rupture and inversion analysis of the rupture process. In addition, the aftershock distribution exhibits obvious north-south segmentation characteristics. These observations suggest that the seismic fault of the main shock was likely to have been the Dengmoduo fault, which is NS and slightly inclined to the west. 展开更多

Since the 1960s, China has been conducting a persistent and systematic observation and monitoring experiment to falsify the hypothesis of premonitory anomalies and the predictability of earthquakes and the application of the assessment of time-dependent seismic hazard to the reduction of earthquake disaster risk. Such an endeavor, with cases of both successes and failures, provided lessons which are heuristic for the studies in earthquake science and social sustainability. This paper provides the back- ground information of such an endeavor, discussing on the achievements and space for improvements of this lane lastin~ ~ncl cantintrint7 ~ffnrl- 展开更多

Under the background of the rapid development of ground mobile communication,the advantages of high coverage,survivability,and flexibility of satellite communication provide air support to the construction of space information network.According to the requirements of the future space information communication,a software-defined Space-Air-Ground Integrated network architecture was proposed.It consisted of layered structure satellite backbone network,deep space communication network,the stratosphere communication network and the ground network.The Space-Air-Ground Integrated network was supported by the satellite backbone network.It provided data relay for the missions such as deep space exploration and controlled the deep-space spacecraft when needed.In addition,it safeguarded the anti-destructibility of stratospheric communication and assisted the stratosphere to supplement ground network communication.In this paper,algorithm requirements of the congestion control and routing of satellite backbone protocols for heterogeneous users’services were proposed.The algorithm requirements of distinguishing different service objects for the deep space communication and stratospheric communication network protocols were described.Considering the realistic demand for the dynamic coverage of the satellite backbone network and node cost,the multi-layer satellite backbone network architecture was constructed.On this basis,the proposed Software-defined Space-Air-Ground Integrated network architecture could be built as a large,scalable and efficient communication network that could be integrated into space,air,and ground. 展开更多

In this article,we review the general characteristics of seismicity in and around China and the overall statistics of earthquake damage in 2021,focusing on several significant events and related scientific topics.Among them,the largest event is the M_(S)7.4 Madoi earthquake in Qinghai Province,northwest China.The event marks another M_(S)≥7 earthquake occurring near the boundary of the Bayan Har Block that has ended a remarkable quiescence of the M_(S)≥7 earthquakes within the Chinese mainland.In addition,the M_(S)6.4 Yangbi earthquake in Yunnan Province,southwest China draws the most attention because of its abundant foreshocks,which are well recorded by the densely distributed seismic stations in the surrounding regions.Regarding this event,we review several recent publications focusing on the Gutenberg-Richter b-value change and the physical mechanism of foreshocks associated with this sequence.The M_(S)6.0 Luxian earthquake in Sichuan Province,southwest China has caused serious damage with a relatively low magnitude,partly because the focal depth of the mainshock is relatively shallow (3.5 km).It is another strong earthquake occurring within the southeast Sichuan basin with low historical seismicity yet has increased significantly since 2015,probably due to shale gas development and associated hydraulic fracturing. 展开更多

Verifiable secret sharing mainly solves the cheating behavior between malicious participants and the ground control center in the satellite network.The verification stage can verify the effectiveness of secret shares issued by the ground control center to each participant and verify the effectiveness of secret shares shown by participants.We use a lot of difficult assumptions based on mathematical problems in the verification stage,such as solving the difficult problem of the discrete logarithm,large integer prime factorization,and so on.Compared with other verifiable secret sharing schemes designed for difficult problems under the same security,the verifiable secret sharing scheme based on the Elliptic Curve Cryptography(ECC)system has the advantages of less computational overhead and shorter key.At present,the binary polynomial is a single secret scheme and cannot provide effective verification.Therefore,based on a Protected Verifiable Synchronous Multi Secret Sharing(PVS-MSS)scheme,this paper is designed based on bivariate asymmetric polynomials.The advanced verifiable attribute is introduced into the Protected Secret Sharing(PSS)scheme.This paper extends the protected synchronous multi-secret sharing scheme based on bivariate polynomial design.The ECC system constructs the security channel between the ground control center and participants and constructs the verification algorithm.Through the verification algorithm,any participant can verify the consistency and effectiveness of the secret shadow and secret share received from other participants or presented by the secret distribution center.Therefore,no additional key agreement protocol is required;participants do not need to negotiate the session key for encryption;the secret share polynomial can generate the session key between participants and speed up the secret reconstruction process.The verification stage has lower computational complexity than the verifiable scheme constructed by Rivest Shamir Adleman (RSA) and other encryption methods. Chinese Remainder Theorem (CRT)is used to update the secret shadow. The secret shadow does not need to beupdated with the change of the scheme shared secret, and the public valueupdate efficiency is higher. Reduce the complexity of sharing secret updatesin a synchronous multi-secret sharing scheme. 展开更多
