The zirconium alloy cladding of PWR fuel rods which undergo high neutron irradiation during service, will cause significant changes in its microstructure, thereby affecting its macroscopic performance. Therefore, the study of neutron irradiation behavior of zirconium alloy cladding is a focus of nuclear field. However, due to the strong radioactivity of materials after neutron irradiation, relevant experiments must be conducted in a hot cell. Therefore, research on the microstructure of irradiated fuel cladding is a difficult task. In this study, the microstructure of M5TM zirconium alloy cladding material after neutron irradiation was studied by means of transmission electron microscope in the hot cell facility of China Institute of Atomic Energy. The samples were from commercial pressurized water reactor AFA3G type spent fuel rods with burnup of 14 GW·d/tU and 41 GW·d/tU, respectively. A cladding sample with a length of about 10 mm from the fuel rod was cut, and the defueling and chemical cleaning in the hot cell were carried out to obtain a clean cladding sample. Then, mechanical sampling methods was used to prepare a thin slice sample of the cladding with 3 mm diameter. Finally, the electrolytic twin-jet thinning method was used to prepare the cladding transmission electron microscopy observation and analysis sample. In addition, to compare the structural changes of zirconium alloy cladding before and after irradiation, the same method was used to prepare un-irradiated observation and analysis samples of the same material. The observation and analysis results of the un-irradiated and irradiated samples reveal that there are native second phase particles (SPPs) inside the matrix structure of the un-irradiated zirconium alloy cladding, and the overall interior of the matrix is with few nano precipitates and no obvious dislocation structure observed. After irradiation, there is no significant difference in the size and distribution of the native SPPs in the matrix compared to the un-irradiated sample, but significant nano precipitates and high-density dislocation structures appear. As the fuel burnup increases, the size of nano precipitates increases. The similarity of dislocation structures between low and high burnup samples indicates that under the burnup of 14 GW·d/tU, the dislocation structures generated by irradiation in the zirconium alloy cladding basically reach saturation state. The results of selected area electron diffraction (SAED) indicate that although there are some amorphous structures in the native SPPs in the matrix after irradiation, the bcc crystal structure is still the main structure, indicating that the SPPs maintain certain irradiation stability at the burnup of 41 GW·d/tU. In addition, the EDS results of the SPPs indicate that with the increase of fuel burnup, the content of Nb element tends to be depleted. Analysis suggests that after neutron irradiation, the Nb atoms in the SPPs of zirconium alloy expand into the Zr matrix, promoting the precipitation of Nb elements in the form of nano Nb rich phases in the Zr matrix.

Groundwater protection is one of the key aspects in the planning and construction of Jinan metro system. Due to the potential risk of groundwater level rising caused by the blocking effect of metro engineering structures on groundwater flow, it is necessary to qualitatively and quantitatively investigate the groundwater level rising risk in the target area of metro engineering construction, and focus on the impact of increasingly frequent extreme rainfall events on the groundwater rising phenomenon. It is mainly focused on the study area of the typical section in Jinan Metro Line 4, the modeling process was optimized based on traditional mesh generation method, and the three-dimensional geological structure containing the metro engineering structure was constructed to establish a numerical model of groundwater unsteady flow, thus to analyze the law and causes of groundwater rising along the metro line. A extreme rainfall event was further designed to simulate the response of groundwater rising. The results show that groundwater rising caused by metro engineering in west plain area of Ji'nan exhibits a spatial distribution pattern, which is mainly controlled by the angle between metro and groundwater flow direction, as well as the thickness of the aquifer. The angle between metro and groundwater flow direction is the dominant factor. Under extreme rainfall scenario, the difference in the magnitude of groundwater rising between different areas along the metro line has increased, while the spatial regularity of groundwater rising remains consistent with normal rainfall scenario. The closer to the groundwater recharge zone in the southern mountainous area, the greater the impact of extreme rainfall events. Generally speaking, short-term extreme rainfall events have minor impact on groundwater rising. The research results can provide reliable data for the groundwater protection in Jinan, and will break new ground in understanding the response of the groundwater flow field to extreme rainfall events during the process of underground engineering.

To investigate the relationship between serum CXC chemokine ligand 1 (CXCL1), CXC chemokine ligand 10 (CXCL10) and nerve injury index and prognosis after minimally invasive puncture and drainage in patients with hypertensive basal ganglia hemorrhage (HBGH). 162 patients with HBGH who were underwent minimally invasive puncture and drainage in the East ward of Liaocheng People's Hospital from February 2020 to April 2023 were selected as study group, and 110 healthy volunteers who were underwent physical examination in our hospital during the same period were selected as control group. The levels of serum CXCL1, CXCL10 and nerve injury indexes [neuron-specific enolase (NSE), glial fibrillary acidic protein (GFAP) and S100茁 protein] were detected and compared between two groups. The correlation between serum CXCL1, CXCL10 and nerve injury indexes were analyzed by Pearson test. All patients were followed up for 3 months, and the prognosis of the patients was evaluated according to the modified Rankin scale (mRS), patients were divided into good prognosis group and poor prognosis group. The prognostic factors of patients with HBGH after minimally invasive puncture and drainage was analyzed by multivariate Logistic regression model. The levels of serum CXCL1 and CXCL10 in study group were higher than those in control group (P<0.05). The levels of serum NSE, GFAP and S100茁 protein in study group were higher than those in control group(P<0.05). Pearson test analysis showed that, serum CXCL1 and CX-CL10 were positively correlated with NSE, GFAP and S100β protein (P<0.05). Univariate analysis showed that, poor prognosis was associated with age, triglyceride (TG), low-density lipoprotein (LDL), prothrombin time (PT), C-reactive protein (CRP), hematoma breaking into the ventricle, hematoma volume, hematoma clearance rate within 24 hours after operation, number of urokinase flushing, recurrence of postoperative intracranial hemorrhage, CXCL1 and CXCL10 (P<0.05). Multivariate Logistic regression analysis showed that, older age, higher LDL, larger hematoma volume, lower hematoma clearance rate within 24 hours after operation, more times of urokinase flushing, higher CXCL1 and higher CXCL10 were risk factors for poor prognosis of HBGH patients after minimally invasive puncture and drainage (P<0.05). Elevate serum CXCL1 and CXCL10 levels in patients with HBGH may lead to nerve injury and poor prognosis. Age, LDL, hematoma volume, hematoma clearance rate within 24 hours after operation, number of urokinase flushes, CXCL1 and CXCL10 are risk factors for poor prognosis in patients with HBGH, which deserves attention.

BACKGROUND: Based on the superior properties of ceramics, bioceramic materials are widely used in bone transplantation and tissue engineering. However, it still faces the problems of low mechanical strength and single biological function, which cannot fully meet the clinical application of bone defect repair. OBJECTIVE: To summarize the research status of bioceramic scaffolds and the effect of manganese doping on the performance of ceramics. METHODS: Chinese and English search terms were “manganese, microelements, ceramic biomaterials, hydroxyapatite, tricalcium phosphate, 3D printing, bone tissue engineering”. Searches were carried out on CNKI, WanFang, PubMed, and Web of Science databases. Relevant articles published from January 1968 to September 2022 were retrieved. According to the inclusion criteria, 84 articles were finally included. RESULTS AND CONCLUSION: Manganese, as an important locally delivering therapeutically active ion, has a positive stimulating effect on cell function and bone formation. The doping of manganese elements can greatly improve the mechanical properties of ceramic scaffolds, further enhance the osteogenic induction ability of ceramic materials, and endow the scaffolds with additional antibacterial properties. (2) Based on manganese-containing bioceramics, the need for bone defect repair was further met through coating, covalently binding bioactive peptides and regulating the valence of doping elements. (3) It began to gradually change from single-element doping to multi-element doping, and strive to give the stent more characteristics. (4) Doping of manganese elements is an effective modification treatment method. Manganese-containing bioceramics have a good application prospect in the repair of fractures and bone defects by combining advanced material manufacturing technology and the excellent biological activity of manganese.

Aiming to address the limitations of traditional channel estimation methods in time- varying channel environments, as well as the low estimation accuracy or high complexity of deep learning-based channel estimation methods, a channel estimation network based on long short-term memory structure is proposed, which consists of a bidirectional long short-term memory (BILSTM) network and a multilayer perceptron (MLP) network, namely BiLSTM-MLP. First, the BiLSTM network is used to learn the time-varying characteristics of the channel. Then, a MLP network is used to denoise and reconstruct the channel estimation. Simulation results show that the proposed channel estimation method has better performance than traditional methods, and has lower complexity and better performance compared with the same type of deep learning-based estimation methods. Furthermore, the proposed method is also robust to different pilot densities. [ABSTRACT FROM AUTHOR]

Mutations in mitochondrial DNA (mtDNA) may lead to a range of mitochondrial diseases that are related to the damage of the mitochondrial respiratory chain. These mitochondrial diseases are characterized by early onset, difficult-to-cure and maternal inheritance. Mutations at site 8 344 in the mitochondrial tRNA lysine gene can result in the reduced translation of the protein encoded by mtDNA and an inadequate energy supply, leading to myoclonic epilepsy associated with ragged red fiber (MERRF) syndrome, with severe myoclonic symptoms, seizures and ataxia. Another characteristic lesion is multiple symmetric lipomatosis (MSL) in the posterior neck and upper back. Among all of pathogenic mtDNA mutations, m.8344A>G mutations were accounted for about 4% . Nuclear gene modification and environmental factors may be involved in the pathogenesis of m.8344A>G mutation. At present, the specific treatment methods for MERRF are lacking. Preimplantation genetic diagnosis and mitochondrial transplantation based on assisted reproductive technology are expected to be new methods for the treatment of this kind of mitochondrial genetic diseases, but the safety and effectiveness still need to be further verified.

To investigate the transportation mechanism of chloride ion in manufactured sand concrete (MSC), the chlorine salt erosion tests under dry-wet cycle were carried out under the conditions of different sand replacement rate, fly ash content and stone powder content. The mass fraction of free chloride ions and diffusion coefficient of chloride ions in concrete were obtained by the experiments. The results show that with the increasing of manufactured sand (MS) replacement, the chloride concentration at the same concrete depth and chloride diffusion coefficient of concrete is decreased with latter increasing. The concrete with 50% manufactured sand has the highest resistance performance to chloride ion penetration. With the increasing of fly ash content, the chloride penetration resistance of manufactured sand concrete is increased with latter decreasing. The manufactured sand concrete with 30% fly ash can resist the chloride penetration with the best effect. Compared with the MS without or containing 11.6% stone powder, the chloride ion erosion resistance of concrete with 5.8% stone power is the strongest. Proper amount of manufactured sand in concrete can improve the durability life of concrete in the dry-wet cycle of chloride solution. [ABSTRACT FROM AUTHOR]

Sparse matrix vector multiplication (SpMV) is widely used in high performance computing. The parallelization of sparse matrix is more difficult than that of dense matrix because of the sparse and irregular distribution of non-zero elements. Therefore, the performance optimization of sparse matrix vector multiplication has always been the research focus in the field of high performance computing. A parallel SpMV algorithm and performance optimization scheme based on the HYB storage format of sparse matrices is designed for the new generation of domestic heterogeneous many-core processor SW26010P. Moreover, considering the difficulty of threshold selection in HYB storage format, a multi-iteration Otsu method is proposed to determine the threshold of HYB. The experimental results show that our design can achieve an average speedup of 23.36 and the best speedup of 34.85, compared with the sequential method on the Main Processing Element (MPE) of SW26010P.

The photodegradation behavior of the mixture of chlorothalonil and profenofos in water was investigated under high pressure mercury lamp (HPML). The results showed that the half-life of chlorothalonil at 3 μmol/L was 122.46 min under the HPML irradiation, and the half-lives of chlorothalonil were 64.54, 38.25 and 33.05 min in the presence of 1, 2 and 3 equivalent of profenofos. The half-lives of 3, 6, and 9 μmol/L profenofos were 87.85, 86.11 and 87.63 min, while they were 85.57, 83.51 and 84.32 min in the presence of chlorothalonil, respectively. This indicates that profenofos promoted the photodegradation of chlorothalonil in water and the promotion effect was increased as the concentration of profenofos increased. Chlorothalonil did not affect the photodegradation of profenofos. The main photodegradation product of chlorothalonil was 4-hydroxyl chlorothalonil with and without profennofos. Five photodegradation products of profenofos were detected, namely, 4-bromo-2-chlorophenyl hydrogen phosphate ethyl ester, O-(4-bromo-2- chlorophenyl)-O-ethyl-S-hydrogen phosphate, O-(2-chlorophenyl)-O-ethyl-S-propyl phosphorothioate, (2-chloro-4-hydroxyphenyl)-O-ethyl-S-propyl phosphorothioate, and 2-chloro-4-bromophenol. Profenofos promoted the degradation of chlotothalonil via the generation of more hydroxyl radicals. This study provides important theoretical support for the evaluation of the environmental ecotoxicity of combined pollution of chlorothalonil and profenofos [ABSTRACT FROM AUTHOR]
