This paper described a simple, rapid and efficient method for the determination of N-methyl carbamate pesticides in tomato, cucumber, carrot and lettuce samples by dispersive liquid-liquid microextraction coupled with HPLC-diode array detection. Some experimental parameters that influenced the extraction efficiency, such as types and volumes of extraction(More)
Dexamethasone palmitate has the potential to inhibit the activity of tumor-associated macrophages, which promote cancer proliferation, invasion, and metastasis; however, only very high and frequent doses are capable of inducing antitumor effects. With the aim to reduce the anticancer dose and decrease the nonspecific toxicity, we designed a liposomal system(More)
Predicting quality of services (QoS) is an important need when ranking cloud services for selection. QoS values of cloud services usually depend heavily on the user’s and service’s environments. Therefore, personalized QoS value prediction for cloud services is more desirable to users. Collaborative Filtering (CF) has recently been applied to personalized(More)
A stochastic singular linear quadratic (LQ) problem is considered under the condition that the state of the dynamics is partially observable. This paper gives the Kalman-Bucy filtering of the state by means of the Girsanov transformation, upon which the suboptimal linear feedback control of the LQ problem is determined. Furthermore, it is shown that the(More)
BACKGROUND Breast feeding can enhance preterm infants' neurodevelopmental outcome, regulate immune function development. This study aims to develop breastfeeding evaluation indicators system in neonatal intensive care units (NICU) and to provide theoretical basis for all-round evaluation of breast feeding quality for hospitalized preterm infants.

Andrographolide (Andro) is an excellent anti-inflammatory bicyclic diterpene γ-lactone. However, the poor solubility limits its application as injection for the treatment of acute inflammation. To meet the clinical needs for emergency, the Andro nanosuspensions injection was first prepared by the wet milling technique. The Andro nanosuspensions were(More)
