    Methods, systems, and programs are provided for presenting professional content in a user feed. The user feed is populated with industry-wise content, using relevance-driven technologies to select the best relevant industry content, while solving the problem of low-content availability for users with few connections. Professional posts created by users in a social network are identified, where each user is associated with an industry as configured in a profile of the user. A score for each identified professional post is calculated and the professional posts are sorted based on their scores. After detecting a request for data to present in a first user feed to a first user that is associated with a first industry, the server selects professional posts based on the industry of the user that created each post. The selected professional posts are then merged with other types of content and presented in the first user feed.

  • The association between serum ferritin levels and post-stroke depression

    Zhu, Lin   Han, Bin   Wang, Liping   Chang, Yaling   Ren, Wenwei   Gu, Yingying   Yan, Mengjiao   Wu, Chaowen   Zhang, Xiang Yang   He, Jincai  

    Highlights • We mainly find that high serum ferritin level is associated with the development of post-stroke depression at two months. • Patients in PSD group were also more likely to had a less education, higher BMI, more thick waistline, more current smoke, more severe stroke. • 28.6% of stroke patients are classified as post-stroke depression at 2 month. Abstract Background Post-stroke depression (PSD) is a common neuropsychiatric affective disorder occurring after stroke. Elevated serum ferritin levels have been reported to contribute to depression. Our aim was to determine whether there is a relationship between serum ferritin levels and PSD. Methods 196 ischemic stroke patients were consecutively recruited within the first 24 h of stroke onset and were followed up for 2 months. Serum ferritin levels were assayed by electrochemiluminescence immunoassay at hospital admission. Clinical depression was diagnosed according to DSM-IV criteria and a HAMD −17 score of ≥7. Meanwhile, 100 normal control subjects were also recruited. Results We found that 56 stroke patients (28.6%) were diagnosed with PSD at two months. There was a significant intergroup difference in serum ferritin levels within 24 h after admission (F=25.044, P<0.001). Serum ferritin levels were significantly higher at admission in PSD patients than in non-PSD patients and normal controls. There was a positive correlation between serum ferritin levels and hs-CRP at admission in PSD patients (r=0.129, P=0.042). In multivariate analyses, serum levels of ferritin≥130.15 µg/L were independently associated with PSD at two months [odds ratio OR=5.388, 95%CI:1.725–16.829; P=0.004] after adjusting for all possible variables. Limitations We excluded patients with severe aphasia and with serious conditions.In addition, the information for dietary intake was not recorded, which may influence body iron stores. Conclusion Our findings show that elevated serum ferritin levels at admission are associated with PSD and may predict its development at 2 months post-stroke.

  • Cutting Tool Life Analysis in Heat-Pipe Assisted Drilling Operations

    Zhu, Lin   Jen, Tien-Chien   Liu, Yong-Bing   Zhao, Jie-Wen   Liu, Wei-Lai   Yen, Yi-Hsin  

    This paper further focuses on the feasibility and effectiveness of heat-pipe cooling in drilling operations based on our previously related work. To achieve this, the authors used a combination of numerical analyses and experimental measurements for drilling in three different cooling conditions, i.e., dry drilling, fluid cooling, and heat-pipe cooling. The evidences obtained from the experimental study and finite element analyses were compared. The results strongly demonstrate that heat-pipe assisted cooling in drilling processes can effectively perform thermal management comparable to the fluid cooling used pervasively in the manufacturing industry, consequently offering the tool life extension.

  • Structural and friction characteristics of g-C3N4/PVDF composites

    Zhu, Lin   Wang, Ya   Hu, Fang   Song, Haojie  

    Highlights • The graphite-like carbon nitride (g-C3N4) was first used as filler to fill in polymer matrix for the modification of polymer. • The structure, morphology, and thermal properties of g-C3N4/PVDF composites were studied by XRD, FT-IR, SEM, TGA. • The friction characteristics of g-C3N4/PVDF composites were studied under dry sliding conditions. Abstract This paper introduced the preparation, structural, and friction characteristics of graphite-like carbon nitride (g-C3N4)/poly(vinylidene difluoride) (PVDF) composites. The g-C3N4/PVDF composites with different g-C3N4 contents were prepared via wet mixing and hot press molding technique. The structure, morphology, thermal properties, and friction characteristics were studied by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), thermo-gravimetric analysis (TGA), and universal micro-tribotester under dry sliding conditions. The XRD and FT-IR studies confirmed the incorporation of g-C3N4 into the PVDF matrix. The SEM results showed good dispersion of g-C3N4 in PVDF matrix. The “onset” temperature To of the composites increased with increasing the content of g-C3N4 filler, which confirmed the enhancement of thermal stability of the composites. The friction characteristics results indicated that small amount of g-C3N4 filler was not beneficial to reduce friction coefficient of the composite while large amount of filler had little effect on it. In addition, the g-C3N4 filler was beneficial to reduce wear loss of the composite, and the wear loss decreased with increasing the content of g-C3N4 filler.
