Objective To build a model of postoperative pathological fracture of the mandibular angular cystic lesions through 3D finite element analysis (FEA), to compare and analyze the biomechanical changes of the mandible after treatment with 8 types of titanium plates, and explore the reliability of titanium plate fixation in preventing pathological fracture of large mandibular cysts. Methods A 30-year-old healthy male was volunteered and the scans of cone beam computed tomography of his mandible were collected to establish a unilateral cystic lesion model of the mandibular angle region to mimic the pathological fracture caused by occlusal force loading. On the basis of the maximum critical cystic lesion size, the biomechanical characteristics and changes in the mandible with 8 different types of titanium plate fixation under the same mechanical conditions were compared. Results The risk of pathological fracture existed when the cystic lesion size in the mandibular angle exceeds 24 mm×30 mm×30 mm. The stress in the lesion area was the lowest when the upper edge was fixed with 1 mm thick titanium plate and bilateral 3 screws, and the lower edge was fixed with 2 mm thick titanium plate and bilateral 4 screws. At the same time the maximum yield strength of the mandible was not exceeded and no pathological fracture of the mandible occurred. Conclusion The incidence of pathological fracture can be reduced by using titanium plate fixation on the upper and lower margins of the mandibular angle after extraoral surgical curettage for large cystic lesions.

To predict rectal and bladder radiation doses during volumetric modulated arc therapy (VMAT) for cervical cancer, a relevant model was established to guide clinical practice. Forty-four cases of cervical cancer treated using VMAT radiotherapy were retrospectively analyzed. The positional relationships of the anatomical spaces between the cervical cancer target volume and the organs at risk (bladder and rectum) were evaluated. Volume and spatial location characteristics of the target volume for the bladder and rectum were inserted as input data in a dose-volume histogram and Python toolkit for statistical analysis. The output data were the bladder and rectal V40 and D33. A mathematical model was developed to predict the bladder and rectal doses. When the actual and predicted values were compared, they were quite similar for both the bladder and rectal doses. The relative error ranges of rectal V40 and D33 were between 1.40% and 6.89%, and between 2.12% and 6.81%, respectively. Likewise, the relative error ranges of bladder V40 and D33 were between 2.47% and 6.67%, and between 0.38% and 4.28%, respectively. There were no significant differences between the actual and predicted values (p>0.05). This model can effectively predict the bladder and rectal doses needed during intensity-modulated radiotherapy for cervical cancer and could serve as a guide for radiotherapy clinical practice.

ObjectiveTo examine the 2-year dynamics of quality of life (QoL) and its influencing factors among community elderly empty-nesters in Ma'anshan city and to provide evidence for developing health care strategies and conducting health care services and health education in the elderly. MethodsWith stratified cluster random sampling, we conducted a baseline survey among 3 476 permanent residents aged 60 years and above in Ma′anshan city from December 2016 to March 2017 and a follow-up interview was conducted from December 2018 to March 2019. Finally, the information on 2 344 elderly being empty-nesters during the period of baseline and follow-up survey were extracted to analyze dynamics and influencing factors of QoL for the elderly empty-nesters. World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF), Activity of Daily Living Scale (ADL), Geriatric Depression Scale-15 (GDS-15), Stress Resilience Quotient Scale (SRQS), and a self-designed questionnaire were used in the study. ResultsCompared to those in the baseline survey in all the elderly empty-nesters, significantly lower scores of WHOQOL-BREF′s psychological domain (55.40 ± 10.76 vs. 65.71 ± 13.52) and social relationship domain (65.70 ± 12.56 vs. 67.43 ± 12.42) were measured in the follow-up survey (both P < 0.05); while there were no significant differences in the scores of physiological domain (64.62 ± 13.92 vs. 65.22 ± 14.55) and environmental domain (63.53 ± 11.90 vs. 63.97 ± 12.67) (both P > 0.05). The results of generalized estimating equation analysis revealed following influencing factors of elderly empty-nesters′ QoL: (1) for psychological domain, aged ≥ 70 years, impaired ADL, and depression were risk factors and moderate or good self-rated economic condition, smoking, alcohol-drinking, taking part in physical exercise, moderate or high resilience were protective factors; (2) for physiological domain, aged ≥ 70 years, with the education of primary school or above, living alone, suffering from a chronic disease, declined or impaired ADL, and depression were risk factors and moderate or good self-rated economic condition, smoking, alcohol-drinking, taking part in physical exercise, moderate or high resilience were protective factors; (3) for social relationship domain, aged 70 – 79 years, living alone, impaired ADL, and depression were risk factors and being female, moderate or good self-rated economic condition, alcohol-drinking, moderate or high resilience were protective factors; and (4) for environmental domain, impaired ADL and depression were risk factors and moderate or good self-rated economic condition, smoking, alcohol- drinking, taking part in physical exercise, moderate or high resilience were protective factors. ConclusionFor community elderly empty-nesters in Ma′anshan city, the main problem in quality of life is the declined quality of psychology and social relationship domains and the quality of the two domains are influenced in common by age, self-rated economic condition, alcohol-drinking, activity of daily living, depression, and resilience.

Most developed countries have reached their carbon emissions peak and entered a period of rapid decline in emissions. These countries have introduced active measures in efforts to achieve carbon neutrality while occupying a dominant position in emerging industries. This article aims to sort out the policies and mechanisms in the process of achieving carbon peaks, promoting carbon neutrality, and promoting social consensus in developed countries, so as to provide reference for China’s carbon peaks and carbon neutrality. By reviewing the experiences of different developed countries, this study compares and analyzes their lessons, summarizes the inspirations that developed countries have brought to us in terms of carbon neutral policy mechanisms, and provides suggestions for China’s path to carbon neutrality. International experience shows that carbon neutrality is a systematic project that requires multiple measures and orderly progress. While reducing transformation costs, it is necessary to accelerate the cultivation of emerging industries; the realization of the carbon neutrality vision requires a sound market mechanism to accelerate the energy market reform; carbon neutrality is not only a transformation of energy and economy, it will also bring changes to individuals' lifestyles. Therefore, the general social consensus is an important guarantee for the successful realization of carbon neutrality. The research suggests that in order to achieve China’s carbon neutrality goals, we must do a good job of top-level design and a step-by-step action plan of carbon emission reducetion; accelerate and deepen energy market reforms; raise social awareness and promote people’s overall consensus on carbon neutrality; and continue to deepen international cooperation.

Ultrasonic assisted method is an effective method to prepare nanomaterials, which can improve their magnetic and optical properties. Described in this paper, GdPO4:Ce, Tb ternary system fluorescent powder was synthesized under different pH conditions by ultrasonic-assisted. Optical and structural properties of the fluorescent powder were determined by X-ray Powder Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Photoluminesce (PL).The following conclusions are drawn:(1) When pH=1, synthetic samples are 15 nm×104 nm hexagonalnanobars like orthophosphate, green phosphor. Cystals prefer growing at the face of (102) and (200). When pH < 1, no samples can be synthesized, whereas granular orthophosphate green phosphors were synthesized when pH>1. (2) A possible formation mechanism has been put forward, which provided further evidence for the fluorescent efficiency enhancement. Because the 5d energy states of Ce3+ ions are high, they can be transferred to the Gd3+ ions efficiently. However, the emission transition peak of Gd3+ ions and the absorption peak of Tb3+ ions have large spectral overlap in the Gd, Ce, Tb ternary system. Therefore, the sequence of energy transmission is the Ce3+→Gd3+→Tb3+. A few Ce3+ ions doping to GdPO4 matrix can enhance fluorescence intensity of the luminescent materials. The result provides theoretical basis for the exploit of rare earth materials.

Objective To observe the effect of Yangxueqingnao granules on c-Fos protein expression in trigeminal nucleus caudalis (TNC) of nitroglycerin-induced migraine rats. Methods A total of 108 healthy male Wistar rats were randomly divided into normal control group, model group, high-dose treatment group, low-dose treatment group, high-dose prevention and low-dose prevention group, and then each group was randomly divided into 3 subgroups: 30, 60 and 180 min group. The experimental migraine rat model was established by subcutaneous injection of nitroglycerin. The rats of normal control group were subcutaneously injected with saline solution of the same dosage. The rats of high- and low-dose treatment group were respectively administered with gastric perfusion of high- and low-dose Yangxueqingnao granules once 10 min after the modeling. The rats of high- and low- dose prevention group were respectively administered with gastric perfusion of high- and low- dose Yangxueqingnao granules for 7 d before the modeling. The rats were sacrificed and the brain tissues were collected at corresponding time points. Related behavior indexes of rats in each group were observed and recorded. TNC c-Fos protein expression changes were measured and compared among different groups. Results At all time points, the c-Fos expression level of model group had no statistical difference from high- and low-dose treatment group (P > 0.05, for all). However, it was higher than that in high-dose prevention group (P = 0.031, 0.000, 0.000), while was only lower than that in low-dose prevention group at 60 and 180 min after modeling (P = 0.000, for all). There was statistical difference between high- and low-dose prevention group only at 30 min after modeling (P = 0.029). Conclusions The Yangxueqingnao granules can significantly decrease TNC c-Fos protein expression, which suggests that the preventive effect of Yangxueqingnao granules may be greater than the therapeutical effect on migraine. Its preventive effect may be associated with the decrease of TNC c-Fos protein expression. doi: 10.3969/j.issn.1672-6731.2014.08.012

The experiment was to investigate the effect of pig epidemic on stability of pork supply chain in China. A total of 12 listed pig companies were selected as a sample and uses panel Tobit estimation to analyze. The results showed that the overall stability of pork supply chain was on the rise in China. By comparison, the stability of the upstream pork supply chain was stronger than that of the downstream pork supply chain. After the outbreak of the pig epidemic, the prices of piglets and corn were significantly negatively correlated with the upstream stability of pork supply chain, while the level of large-scale pig breeding was significantly positively correlated with the upstream stability of pork supply chain. The prices of piglets and corn were negatively correlated with the downstream stability of pork supply chain, while the prices of chicken and beef were positively correlated with the downstream stability of pork supply chain. The experiment indicates that on premise of effectively controlling pig epidemic, the government and enterprises should take differentiated measures to address different factors affecting the stability of upstream and downstream pork supply chain.

[Objectives] To determine the optimal reproduction and storage conditions for the Hyphantria cunea nudeopolyhedrovirus (HcNPV) in order to provide a theoretical basis and technological support for the commercial production of this virus. [Methods] The effects of different larval instars, virus concentration, duration, temperature and population density, were analyzed to identify the optimal condition for HcNPV reproduction in vivo. Effects of different formulations, times, temperatures and adjuvants on the stability of HcNPV storage were also investigated to determine the optimal HcNPV bioactivity assay method. In feeding bioassays, the number of proliferating occlusion bodies (OB) were recorded with a hemocytometer, and the lethal time (LT50) was calculated to quantify the insecticidal activity of HcNPV Third instar larvae fed a diet with a HcNPV concentration of 1x106 OBmL-1 were used for follow-up experiments. [Results] OB proliferation in 5th instar larvae reared on an artificial diet containing HcNPV at a concentration of 1x106 OBmL-1 was significantly higher (1.16x1010 OB per larva) than in other treatments. The optimal temperature for HcNPV reproduction was 20 °C, which resulted in 5.06x109 OB per larva. The abundance of HcNPV virions significantly decreased from 3.42x109 OB per larva after feeding for 1 day to 0.97x109 OB per larva after feeding for 5 days. Larvae kept at a density of 100 larvae/box (0.05 larvae/cm²) had 4.94x109 OB per larva, which was significantly higher than that of those kept at densities of 200, 300, 400, 500 larvae/box. The LT50 of 3rd instar larvae infected from insect pulp and freeze-dried insect pulp was significantly lower than that of those infected from virus suspension and freeze-dried virus suspension. There was no significant change in the insecticidal activity of HcNPV when stored for less than 12 months and insecticidal activity did not change significantly over a range of storage temperatures from - 20 to 25 °C. The best preservatives were sucrose (50%) and sodium chloride (5%), which had in LT50 values of 4.94 days and 4.97 days, respectively. [Conclusion] The highest yield of HcNPV was achieved by giving 5th instar H. cunea larvae a single feed of an artificial diet containing HcNPV inoculum at a concentration of 1x106 OB mL-1 and keeping larvae at a density of 0.05 larvae/cm² at a temperature of 20 °C. Grinding the bodies of diseased larvae into a slurry, adding sucrose (50%) or sodium chloride (5%) as adjuvants, and storing the resultant homogenate in a refrigerator at - 20 °C, allowed HcNPV to be stored for up to 12 months with no loss in insecticidal activity.

The experiment was to study the effect of adding different dosages of fermented feed to production performance, digestion and metabolism, egg quality, serum biochemical indexes and nitrogen excretion of laying hens. Hyline brown commercial laying hens with no significant difference in health status and body weight at the age of 59 w were selected and randomly divided into three treatment groups, with six replicates in each group and 45 chickens in each replicate. The laying hens in control group were fed with basal diet, and the laying hens in test group were fed with 40 and 60 g/kg of fermented feed in basal diet. The test period was 6 w. The results showed that there was no significant change in production performance and digestion and metabolism of laying hens after feeding fermented diet (P>0.05), but the teratobreaking rate of eggs was decreased (P=0.064). Compared with control group, the serum cholesterol level in 40 g/kg group and 60 g/kg group of laying hens was significantly decreased 50.64% and 45.11%, respectively (P<0.05). The color grade of egg yolk and dry matter and crude protein content of eggs were significantly increased (P<0.05), the absolute nitrogen excretion of fresh manure of laying hens was significantly reduced (P<0.01). The absolute nitrogen excretion of fresh manure decreased 36.11%, and the crude protein content of eggs increased by 5.47%. The experiment indicates that adding fermented feed to diet of laying hens can improve the color grade of egg yolks, promote the deposition of egg nutrients, which has the potential to promote economic benefits. The addition amount of 60 g/kg is more appropriate. [ABSTRACT FROM AUTHOR]

In order to explore the potential application of laser heating nanofluid flow strip boiling, the related factors of the threshold of light energy intensity needed for the bubble nucleation in the flow boiling of nanofluids under pulsed laser heating have been experimentally investigated. The heat source uses a pulsed laser with a wavelength of 792 nm. The laser beam can ex cite the longitudinal mode of localized surface plasma resonance in gold nanorods having diameters of 101 nm, and 433 nm in length. At a concentration of 1.824 µg/mL of nanofluid with gold nanorods, the effects of inlet temperature of the nanofluid, laser pulse frequency (at a pulse duty ratio of 50%) and pulse period of the laser (at a pulse duration of 10 ms) on the minimum laser intensity for bubble generation are investigated. The results show that higher inlet temperature of the nanofluid can lower the laser intensity needed for the vapor generation, and increasing the pulse frequency of the laser with a given pulse duration can decrease the minimum laser intensity with the same observation time. The minimum laser intensity required for bubble generation in the nanofluid has a maximum value at a laser pulse frequency of 100 Hz, which is independent of inlet velocity. [ABSTRACT FROM AUTHOR]

Aiming at the problems oi excessive and unreasonable fertilizer application, lower nitrogen use efficiency, increasing N2O emission from soil and fertilizer in current intensified agricultural productions, a field experiment was conducted to study the effects oi dicyandiamide (DCD) combined with nitrogen fertilizer application at different levels, i.e., 150, 225, 300 kg.hm-2, on N2O emission and relevant economic benefit in a typical winter wheat-summer maize rotation system in North China Plain. The results showed that DCD application decreased N2O emission fluxes and cumulative emissions by 25.6%-32.1% and 23.1%-31.1% in the year-round. There was a significant positive exponential correlation between N2O flux and soil surface temperature or soil moisture content. The effect of soil moisture on N2O emission was stronger in wheat season than in maize season, while the effect of temperature on N2O emission was on the contrary. The yields of winter wheat and summer maize with DCD addition were increased by 16.7%-24.6% and 29.8%-34.5%, respectively, and the average economic income of two seasons was increased by 7973.2 yuan.hm-2. Therefore, appropriate rate of N fertilizer combined with DCD could not only increase crop yield and economic income, but also reduce N2O emission. Considering environmental and economic benefit under this experimental condition, DCD combined with nitrogen of moderate level (total N amount 225 kg.hm-2) was a good nitrogen management mode in North China.

Objective To observe the association between adiponectin gene polymorphism, serum adiponectin levels with the incidence of coronary artery disease (CAD) and the severity of coronary artery stenosis in patients with essential hypertension (EH). Methods A total of 414 patients with EH (234 cases with CAD and 180 cases without CAD) and 185 control subjects were recruited in this study. Serum adiponectin levels were measured by enzyme-linked immunosorbent assay (ELISA). Adiponectin single-nucleotide polymorphisms rs266729, rs7649121, rs1501299 and rs3774262 were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results Serum adiponectin levels were significantly lower in EH with CAD group than those in control group and EH without CAD group. Adiponectin SNP rs7649121 AT genotype reduced the risk of CAD compared with AA genotype (adjusted OR=0.566, 95% CI 0.346-0.925, P=0.023). Logistic regression analysis showed that age and LDL-C were risk factors of CAD, and adiponectin was the protective factor for CAD in EH patients. The severity of coronary artery stenosis was negatively related to the level of adiponectin. Adiponectin levels were not affected by the adiponectin gene polymorphism. Conclusion The decreased serum adiponectin level was the independent risk factor for CAD in EH patients, which was negatively related to the severity of coronary artery stenosis. Adiponectin SNP rs7649121 may contribute to the risk factors of CAD in EH patients. [ABSTRACT FROM AUTHOR]

Sparse representation has been deeply studied for its robustness and effectiveness, while its complex computation reduces the efficiency; so many methods combined with nearest neighbor, subspace learning and sparse representation to reduce computation are proposed. Considering the intra-class scatter is small while the inter-class scatter is large in the projection subspace, and samples of a same class have similar contributions to reconstruct a given sample, so dealing with the problem by class is more reasonable. Weighted nearest neighbor classes based block-sparse representation for image recognition is presented in this paper. First, k neighbor classes are selected and the corresponding coefficients are preserved to weight samples of the k classes, and then the test sample is represented by block-sparse representation for classification in the subspace. Finally, it classifies the test sample into the class with lowest residual. The experiments on AR, Yale B, MNIST and PIE database verify the proposed method's effectiveness and robustness.

To realize compact and high performance filters, two novel centrally loaded E-shape dual-mode resonators are presented and analyzed. Simulation and optimization are made by use of ADS and HFSS. Compared with the square loop resonator, the size reduction of the proposed resonators are 42.8% and 52.6% respectively. Measured results show that the filters have the center frequency of 4.22 GHz and 3.75 GHz, the fractional bandwidth of 33.6% and 9.1%, the minimum insert loss in passband of -0.9 dB and -1.9 dB respectively. The measured positions of the transmission zeros agree well with the simulations. As The filters feature not only compact size, low insertion loss, but also wide stopband and controllable transmission zeros. Short stub loaded dual-mode filter has better performances in selectivity and out-of-band rejection and it will find wide application in microwave circuits. [ABSTRACT FROM AUTHOR]

However, it was higher than that in high-dose prevention group (P = 0.031, 0.000, 0.000), while was only lower than that in low-dose prevention group at 60 and 180 min after modeling (P = 0.000, for all). There was statistical difference between high- and low-dose prevention group only at 30 min after modeling (P = 0.029). Conclusions The Yangxueqingnao granules can significantly decrease TNC c-Fos protein expression, which suggests that the preventive effect of Yangxueqingnao granules may be greater than the therapeutical effect on migraine. Its preventive effect may be associated with the decrease of TNC c-Fos protein expression. [ABSTRACT FROM AUTHOR]

To overcome the shortages of current widely used static priority-driven round robin scheduling algorithm in RTOS, this paper proposed a static priority-driven short job first dynamic round-robin scheduling algorithm, called LC algorithm. The algorithm used SJF scheduling policy and dynamically allocated time slice, it set two ready queues RQ0 and RQ1 for each static priority, inserted short burst time processes into RQ1 and long burst time processes into RQ0. LC algorithm calculated waiting time for long burst time processes in RQ0, if the waiting time was too long, it reinserted the first RQ0 process into the tail of RQ1. Simulation test shows that the LC algorithm can maintain excellent performance in all cases. LC algorithm makes a good tradeoff between schedule overhead, performance, response speed and fairness. Moreover, it isn't sensitive to inaccuracy of burst time prediction, so it is better than some other improved RR algorithms. [ABSTRACT FROM AUTHOR]

PURPOSE: To collect the cases which have caries on the mandibular second molar and analyze the caries status and correlative factors. METHODS: Patients treated in the Department of Endodontics in West China Hospital of Stomatology were randomly collected. The baseline information, primary sites and severity of dental caries on the mandibular second molar, and eruption pattern of the mandibular third molar were recorded. The data was analyzed with SPSS13.0 software package. RESULTS: Four hundred eighty-one patients including 227 males and 254 females were collected. Caries on the mandibular second molar starting from the occlusal, distal proximal and buccal surfaces accounted for 33.8%, 33.2% and 24.4%, respectively. Caries involving dental pulp (49.7%) were significantly more than deep and shallow to moderate caries (31.7% and 18.6%). Gender was not correlated with the site and severity of caries. However, impacted mandibular third molars and age were significantly related to both caries site and severity. CONCLUSIONS: Occlusal and distal proximal surfaces are the most predisposed sites to have caries on mandibular second molar. Impacted mandibular third molar and age are significantly related to caries of mandibular second molar. [ABSTRACT FROM AUTHOR]

In classification problem of multiple observation sets, multiple observations of the same object were viewed as a whole for recognition, which respect all single samples equally. Considering the different amount of discriminative information from each single sample, with regard to how to exploit their respective different discriminant information, multiple observation sets classification algorithm based on joint sample weighted sparse representation is proposed. Multiple observation sets are first divided into single samples and each sample is processed separately by a sparse solution obtained its respective sparsity and residual, then use them jointly to obtain its different reliability. After that, each single sample is weighted by corresponding realibility, the weighted multiple observation sets are reconstructed. Lastly, the classification is completed by global sparse representation. Extensive comparative experiments are conducted on ETH-80 object dataset, CMU-PIE face dataset and BANCA datasets, the results verify the effectiveness of the proposed algorithm, enhancing the recognition accuracy and the robust of the algorithm.

Experiment results on AR dataset prove our method perform better in recognition rate than BS (Block Sparse Representation), NS (Nearest Subspace) and SRC in low-dimension. [ABSTRACT FROM AUTHOR]

The HOG descriptor takes full advantage of the information of gradient direction and amplitude distribution, which is widely applied in pedestrians, vehicles and other specific object detection and location task. In order to introduce curvature information and gradient information to the HOG descriptor, this paper proposes an improved object detection algorithm based on HOG algorithm. Firstly, calculate the curvature information and gradient information, apply the gradient amplitude and direction as constraint condition to obtain curvature distribution histogram, and then build a new feature descriptor with better detection performance, finally, use the new feature vector to detect objects. Experiment results in the shape ETZH database and INRIA horse database show that the proposed algorithm can obtain better detection performance and a higher accuracy. [ABSTRACT FROM AUTHOR]

Nano-CoOOH was synthesized by co-precipitation method using CoSO4 · 6H2O and NaOH as resources and characterized by X-ray diffraction (XRD), transmis sion electron microscope (TEM), and the thermogravimetric (TG-DTA). The electro-chemical properties as the anode electrode materials for lithium ion batteries were studied by charge-discharge method. The results showed that the sizes of Nano-CoOOH pa-icles could be well controlled. When used as the anode materials for lithium ion batteries, the discharge capacity of the first cycle could reach as high as 2100 mAh · g ¹ and finally stablize at about 800 mAh · g ¹ after 20 cycles. These results showed that this material could be one of the candidates for the negative materials. [ABSTRACT FROM AUTHOR]

The flow in turbomachiney is inherently unsteady, so investigating the unsteady interaction between the downstream pressure field and the end-wall flows is very important for improving the performance of low-aspect-ratio, high-loaded turbine. This paper presents the results of a numerical study of the interaction between the end-wall secondary flow and tip leakage flow of the rotor and the downstream potential field of the stator in a low-aspect-ratio, subsonic turbine. The flow diagrams of tran-sient results were analyzed in detail. The results indicate that the entropy rise and the efficiency at the exit of the rotor blade showed a significant periodic variation due to the unsteady interaction of the downstream pressure field. The periodic variation of the rotor performance is due to the unsteady interactions of the downstream pressure field with the secondary flow vortex and the tip leakage vortex, which has been interpreted using the theory of kinematic vortex transport.
