Production Cross Section of Neutron-Rich Calcium Isotopes in Heavy Ion Collisions
Donghong Zhang,Wenjie Xie,Jun Su,Fengshou Zhang
Physics , 2014, DOI: 10.1088/1674-1137/39/4/044103
Abstract: Based on the isospin-dependent quantum molecular dynamics model along with the GEMINI model, heavy-ion collisions at intermediate energies are studied. We calculate the production cross sections of different fragments for reactions of 112Sn+112Sn and 124Sn+124Sn at different beam energies. The species and production cross sections of neutron-rich isotopes are generally dependent on the isospin of the system and the incident energies. The nucleon 48Ca and 54Ca are more productive for the neutron-rich system at 30 to 150 MeV/nucleon.

Abstract: Dealing with issues such as too simple image features and word noise inference in product image sentence amnotation, a product image sentence annotation model focusing on image feature learning and key words summarization is described. Three kernel descriptors such as gradient, shape, and color are extracted, respectively. Feature late-fusion is executed in turn by the multiple kernel learning model to obtain more discriminant image features. Absolute rank and relative rank of the tag-rank model are used to boost the key words’ weights. A new word integration algorithm named word sequence blocks building(WSBB)is designed to create N-gram word sequences. Sentences are generated according to the N-gram word sequences and predefined templates. Experimental results show that both the BLEU-1 scores and BLEU-2 scores of the sentences are superior to those of the state-of-art baselines.

Abstract: Background: Chronic Obstructive Pulmonary Disease (COPD) is a common and frequently occurring disease, which not only has a higher fatality rate, but also leads to loss of labor force and an obvious decrease in the quality of life in the course of long-term disease, patients with chronic obstructive pulmonary disease complicated with anxiety and depression are a major public health problem. Objective: To investigate the status of anxiety, depression and quality of life and related factors in patients with COPD. Methods: One hundred patients admitted to the Department of Respiratory and Critical Care Medicine of the First Affiliated Hospital of Dali University with chronic obstructive pulmonary disease evaluated by anxiety self-assessment scale, depression self-assessment scale and quality of life rating scale for patients with chronic obstructive pulmonary disease. Results: The incidence of anxiety in COPD patients was 82.5%, and the incidence of depression was 87.3%. The probability of both anxiety and depression was high, and the prevalence of women was significantly higher than that of men. Correlation analysis and logistic regression results showed that education level was negatively correlated with the occurrence of anxiety, and age was positively correlated with the occurrence of anxiety. Elderly patients were prone to anxiety and had lower quality of life. Conclusion: The older and less educated the COPD patients are, the higher the incidence of anxiety and depression, and the higher the incidence in female patients.

Abstract: Seventy cases of ESCC with 60 controls and 39 cases of CSCC with 54 controls collected from patients in Shantou region in China were compared for the distributions of HPV-16, -18 and -58; viral load; and viral integration using real-time PCR assay and HPV-16 expression using immunostaining.The detection rates and viral loads of HR-HPV infection were significantly lower in ESCC than in CSCC (50.0% vs. 79.48%, P = 0.005; 2.55 ± 3.19 vs. 361.29 ± 441.75, P = 0.002, respectively). The combined integration level of HPV-16, -18 and -58 was slightly lower in ESCC than in CSCC (P = 0.022). HPV-16 expression was detected in 59.26% of ESCC tissue and significantly associated with tumour grade (P = 0.027).High levels of HR-HPV expression and integration may be an indicator of the risk of ESCC, at least for patients in the Shantou region of China. However, a relatively low HPV copy number and infection rate in ESCC is unlikely to play an essential a role in the carcinogenesis of ESCC as in cervical cancer. Factors other than HR-HPV infection may contribute to the carcinogenesis of ESCC.Esophageal squamous cell carcinoma (ESCC) occurs worldwide and has a variable geographic distribution [1]. The Shantou coastal area of eastern Guangdong province, in southern China, has a high incidence of esophageal carcinoma (EC) [2]. Tobacco smoking, alcohol drinking, dietary deficiency, and some local factors, including drinking hot tea and consumption of fermented fish sauce, may be involved in the development of EC in this region [3,4]. However, the etiology of EC is still largely unknown.The association of HPV infection and EC has been reported in the last 30 years, especially in geographic areas with a high incidence of EC. However, unlike cervical carcinoma, with its almost conclusive association with HPV, the causal role of HPV infection in EC remains controversial. This lack of association is due in part to the wide variation in reported infection rates among different studies (from 0%
Applying foliar stoichiometric traits of plants to determine fertilization for a mixed pine-oak stand in the Qinling Mountains, China

Abstract: The Chinese Natural Forest Protection program has been conducted nationwide and has achieved resounding success. However, timber importation has increased; therefore, producing more domestic timber is critical to meet the demand for raw materials. Fertilization is one of the most effective silviculture practices used to improve tree and stand growth. However, determining the appropriate type and amount of elements is necessary for effective fertilization of big timber in different forest types and environmental conditions. Stoichiometric theory provides the criteria to assess nutrient limitation in plants and offers important insight into fertilizer requirements of forested ecosystems
Metaphors in the First Stanza of Ode to the West Wind: A Cognitive Linguistic Approach
Donghong Zhan
Asian Social Science , 2009, DOI: 10.5539/ass.v5n7p18
Abstract: Metaphor is ubiquitous and it is a way of conceptualizing human experiences. But the metaphors used in poetry are not the same as those employed in daily life although the metaphors maneuvered in poems are often based on those used in daily life. The metaphors employed in poems are always extended, elaborated and compressed into one poem by poets. And this is what makes poetic metaphors different from common metaphors. Ode to the West Wind is one of the best lyric and political poems of the English romantic poet Percy Bysshe Shelley. And the metaphors maneuvered in this poem are a good evidence of this point.

Abstract: BTBR T+tf/J (BTBR) mice have recently been reported to have behaviors that resemble those of autistic individuals, in that this strain has impairments in social interactions and a restricted repetitive and stereotyped pattern of behaviors. Since immune responses, including autoimmune responses, are known to affect behavior, and individuals with autism have aberrant immune activities, we evaluated the immune system of BTBR mice, and compared their immunity and degree of neuroinflammation with that of C57BL/6 (B6) mice, a highly social control strain, and with F1 offspring. Mice were assessed at postnatal day (pnd) 21 and after behavioral analysis at pnd70. BTBR mice had significantly higher amounts of serum IgG and IgE, of IgG anti-brain antibodies (Abs), and of IgG and IgE deposited in the brain, elevated expression of cytokines, especially IL-33 IL-18, and IL-1β in the brain, and an increased proportion of MHC class II-expressing microglia compared to B6 mice. The F1 mice had intermediate levels of Abs and cytokines as well as social activity. The high Ab levels of BTBR mice are in agreement with their increased numbers of CD40hi/I-Ahi B cells and IgG-secreting B cells. Upon immunization with KLH, the BTBR mice produced 2–3 times more anti-KLH Abs than B6 mice. In contrast to humoral immunity, BTBR mice are significantly more susceptible to listeriosis than B6 or BALB/c mice. The Th2-like immune profile of the BTBR mice and their constitutive neuroinflammation suggests that an autoimmune profile is implicated in their aberrant behaviors, as has been suggested for some humans with autism.

Molecules , 2013, DOI: 10.3390/molecules18010561
Abstract: The degradation of caffeic acid under ultrasound treatment in a model system was investigated. The type of solvent and temperature were important factors in determining the outcome of the degradation reactions. Liquid height, ultrasonic intensity and duty cycle only affected degradation rate, but did not change the nature of the degradation. The degradation rate of caffeic acid decreased with increasing temperature. Degradation kinetics of caffeic acid under ultrasound fitted a zero-order reaction from ？5 to 25 °C. Caffeic acid underwent decomposition and oligomerization reactions under ultrasound. The degradation products were tentatively identified by FT-IR and HPLC-UV-ESIMS to include the corresponding decarboxylation products and their dimers.
