Building the core competitiveness and improving the innovation performance of the team is becoming increasingly important to keep pace with changing economic environments and emerging technological opportunities. However, the dark side of knowledge transfer can lead to a series of harmful consequences which will destroy the core competitiveness and creativity of the team, even will reduce the innovation performance of the team. And the literature on the dark side knowledge transfer is very fragmented and lack of coherence, leading to more needs to systematically sort through studies on the dark sides of knowledge transfer. Therefore, this paper aims at reviewing the extant knowledge transfer and its dark side research field to understand the historical roots, its temporal progression, current state and potential future in a meaningful way. Data for this study were retrieved from the Web of Science database using a systematic literature search process. The bibliometric characteristics of 926 research documents were analyzed using bibliometric and knowledge mapping analysis. Based on a visual analysis tool VOSviewer, this paper provides a comprehensive review of the dark side of the knowledge transfer research field. The authors provide a quantitative review of these studies through the use of three bibliometric techniques: general description analysis, co-word analysis, and bibliographic coupling. This paper provides an overview of the annual publication trends, most productive and impactful countries, authors, and sources. The authors present an overview of historical progression, current status, and future directions of the dark side of knowledge transfer research based on an in-depth content analysis of these knowledge maps. This is a unique endeavor to accomplish a systematic bibliometric analysis of the dark side of knowledge transfer, offering an intellectual framework which reveals the antecedents and consequences of the dark side of knowledge transfer.

Infantile haemangioma (IH) is a benign vascular tumour type that occurs in 3-10% of infants. In the present meta-analysis, previous studies comparing clinical outcomes, including the recovery rate and haemangioma activity score (HAS), adverse effects and relapse rates, were compared between patients treated with atenolol and those treated with propranolol for IH. A systematic search in various databases, including Medline, Cochrane Controlled Register of Trials, ScienceDirect and Google Scholar from inception until July 2019 was performed. The Cochrane risk of bias tool was used to assess the quality of published trials. A meta-analysis with a random-effects model and reported pooled mean differences (MD) or odds ratios (OR) with 95% CIs was performed. In total, 8 studies including 608 participants were analyzed. Only 2 studies were randomized controlled trials, while the majority of studies had low or unclear bias risks. Except for the response to medication (pooled OR=1.49; 95% CI, 0.85-2.18), all other outcomes (HAS, adverse reactions and relapse rate) were better for the atenolol group than the propranolol group. Atenolol resulted in better HAS (pooled MD=0.16; 95% CI, -0.42 to 0.73). Propranolol had more adverse reactions (pooled OR=2.17; 95% CI, 0.93-5.06) and a higher relapse rate (pooled OR, 1.67; 95% CI, 0.44-6.41) when compared to atenolol. However, these findings were not statistically significant. The results of this analysis suggest that atenolol may be non-inferior to propranolol and may offer advantages, including lower adverse reactions and relapse rates.

Cervical carcinoma (CC) ranks among the top four most common cancers in women worldwide. Over the last 10 years, several studies have confirmed the inhibitory effects of tetramethylpyrazine (TMP) on numerous types of cancer. To investigate the inhibitory effect of TMP on the CC C33A cell line, MTT and colony formation assays were performed to determine how TMP affects C33A cell survival and proliferation. Proliferation-, migration- and hedgehog (Hh) signaling pathway-related protein expression levels were analyzed via western blotting. Wound-healing and Transwell assays were used to detect the migration and invasion abilities of C33A cells, respectively. The results indicated that TMP markedly reduced the C33A cell survival rate compared with the cervical epithelial Ect1 cell line, which was unaffected by TMP treatment. C33A cell proliferation was downregulated by TMP treatment in a dose-dependent manner. TMP treatment also significantly inhibited C33A cell migration and invasiveness in a dose-dependent manner. Furthermore, TMP inhibited the Hh signaling pathway, as demonstrated by a dose-dependent reduction in Hh-related protein expression levels following TMP treatment. Subsequently, treatment with smoothened agonist increased the proliferation, invasiveness and migration abilities of TMP-treated C33A cells. In conclusion, TMP inhibited the proliferation, migration and invasiveness of CC cells via inhibition of the Hh signaling pathway.

In this paper, a test structure of ring oscillator (RO) with addressable devices under test (DUTs) is described for the extracting of MOSFET capacitance-voltage (C-V) curves. With a high oscillation frequency, the influence of the gate-leakage current will be reduced to negligible. The addressable array and its calibration method in this work mitigate the impact from the layout, spatial and process variations, and improve the test accuracy. Moreover, the consumption of the layout area and test lines are also reduced by this structure.

Propranolol is the mainstay of treatment for infantile hemangiomas (IHs) benefited from its low complication in the present study. However, it has an uncertainty treating period with cumbersome methods which may be related to clinical features. This study sought to considered possible influences of short-term efficacy to medication. Retrospective analysis of 82 patients with IHs treated by propranolol was performed. The patients were grouped according to effect (excellent, good and fair/poor). ANOVA or t test was used to assess the relationships between effect and clinical features of IHs. Twenty-seven patients were males and 55 were females. The median age of treatment initiation was 3.5 (±2.11) months. Mean follow-up time for the group was 6.2 months (1.5–16 months). There were no significant associations between short-term efficacy and gender, time points of treatment, diameter of tumor and multifocality. However, tumor thickness was associated with short-term efficacy (P = .013). Moreover, an obvious difference of short-term efficacy has been found when tumor thickness

In view of the situation that heavy oil well production fluid needs to be gathered and transferred by heating or with heat water to ensure the normal operation, a kind of cold transportation viscosity reducer was developed through the compounding of different types of surfactants and the screening of functional additives, which adapt to the oil well produced fluid without heating or watering gathering process, for saving energy, reducing consumption and increasing efficiency, while meeting the environmental needs. After on-site practical applications of 30 pipelines with different physical properties of crude oil, the average pressure of gathering pipelines dropped 1.3 Mpa, which has achieved good results. Application results show that the cold transportation viscosity reducer has strong adaptability and less usage, and it has no influence on demulsification, while having a high value of applications and a broad market prospect.
