Abstract

In the present work, we performed a theoretical work to investigate how a make-to-order (MTO) company operates its producing plan for dealing with a rush-order-inserting problem. Firstly, we constructed two models, the time-minimized and cost-minimized model, to investigate the energy-cost generated by the prey during experiencing the pursuit-evasion game. Inspired by the natural pursuit-evasion game, two models have been extended and re-constructed to understand the cost of MTO company induced by the rush-order-inserting problem. In particular, the present results revealed that the optimal strategy adopted by the prey and the MTO manager are significantly coincident. This work provides helpful findings for operating the rush-order-inserting problem and indicates the natural behavior can be appropriately adopted to guide the manager's decision making.

111. A long-wavelength quantum dot-concentric Förster resonance energy transfer configuration: characterization and application in a multiplexed hybridization assay

Author

Li, Jia Jun

Abstract

Concentric Förster resonance energy transfer (cFRET) based on fluorescent quantum dots as nanoscaffolds is a promising strategy for multiplexed bioanalysis and bioimaging. To expand the scope of prototypical cFRET strategy, which was limited to a particular combination of quantum dot (QD), peptides and fluorescent dyes, work in this thesis adopted a combination of an orange-emitting QD605 and red/deep-red fluorescent dyes Alexa Fluor 633 and Alexa Fluor 680 for the design of a long-wavelength cFRET configuration. This new configuration has shown certain superior properties compared to the prototypical one. Although more susceptible to photobleaching, the long-wavelength cFRET configuration offers much higher signal-to-background ratios in biological samples due to both the excellent brightness of the orange-emitting QD605 and long-wavelength excitation and emission. A rate analysis of both of the competitive and sequential energy transfer pathways revealed the dominant competitive pathway in the long-wavelength cFRET configuration, contrary to a dominant sequential pathway in the prototypical configuration. Moreover, to expand cFRET beyond peptide-linked configurations, an oligonucleotide-linked cFRET configuration was constructed and used to demonstrate the multiplexed detection of unlabeled target oligonucleotides through efficient toehold-mediated strand displacement. Overall, work in this thesis has contributed to evidence of cFRET as a general strategy and expanded it to a wider range of applications.

Abstract

In this paper, a theoretical study is conducted to investigate the propulsive performance of two flapping foils with the inline arrangement. At first, we consider the propulsive performance of two flapping foils when they are relative static to each other, that is, the horizontal gap between the foils is fixed. Then, we provide a model to consider the dynamic stability of the two-foil system when the relative movement between them has occurred, that is, the horizontal gap between the two foils can be changed depending on the propulsive force acting on the foil. This work provides helpful suggestions for managing the trajectories and energy cost of multiple bio-inspired robotics. [ABSTRACT FROM AUTHOR]

Abstract

The current study was conducted to determine the effects of dietary Radix bupleuriroot extract (RBE) on the growth performance, muscle composition, immune responses, and microcystin-LR (MC-LR) stress resistance of juvenile red claw crayfish (Cherax quadricarinatus). Crayfish (0.28 ± 0.02 g) were fed experimental diets containing graded RBE levels as 0 (Diet 1), 0.2 (Diet 2), 0.4 (Diet 3), 0.6 (Diet 4), 0.8 (Diet 5) and 1.6 (Diet 6) g/kg RBE for 8 weeks. The results showed that specific growth rate (SGR) and weight gain rate (WGR) were significantly increased in the Diet 4 and Diet 5 groups. The content of muscle crude protein was significantly increased in the Diet 4 and Diet 5 groups, and the crude lipid content was significantly decreased in the Diet 5 group. Dietary RBE did not alter the structure of the hepatopancreas. Total antioxidant capacity (T-AOC) and superoxide dismutase (SOD) activities in hepatopancreas and plasma were significantly increased in Diet 4 and Diet 5 groups compared to the control group, while the malondialdehyde (MDA) content in hepatopancreas and plasma was significantly decreased in the Diet 5 group. Plasma alkaline phosphatase (AKP) activity was significantly higher in the Diet 3, Diet 4, Diet 5 and Diet 6 groups. Hepatopancreas and plasma PO activities were significantly increased in Diet 4 and Diet 5 groups. The mRNA levels of extracellular copper/zinc superoxide dismutase (ecCu, Zn-SOD), hemocyanin, C-type lysozyme (C-LZM), GPx, and selenium-dependent glutathione peroxidase (Se-GPx) were significantly up-regulated in the hepatopancreas of crayfish fed Diet 5 than those of the control group. After MC-LR challenge, the survival rates of crayfish in the Diet 4 and Diet 5 groups were significantly higher than the control group. The findings suggest that 0.6–0.8 g/kg of RBE can improve growth and muscle composition and enhance immunity and microcystin-LR resistance.

Abstract

Jia-Jun Li, Wen-Xiang Huang, Zheng-Yu Shi, Qiu Sun, Xiao-Juan Xin, Jin-Qiu Zhao, Zhen Yin Department of Infectious Diseases, The First Affiliated Hospital of Chongqing Medical University, Chongqing, People’s Republic of China Background: Fever of unknown origin (FUO) has always been a challenging problem for physicians since it was first reported half a century ago. This study aimed to investigate the clinical features of FUO and to compare the clinical significance of the classical diagnostic criteria and the Chinese revised diagnostic criteria of FUO. Methods: We retrospectively collected a series of 140 patients admitted to our hospital between September 2011 and June 2013 because of prolonged febrile illnesses (lasting at least 2 weeks, temperature ≥38.5°C) without diagnosis and categorized them into two groups according to the Chinese revised diagnostic criteria (group A) and classical diagnostic criteria (group B) for FUO. The A group included patients presenting with fever persisting between 2 and 3 weeks with the diagnosis remaining uncertain after three outpatient visits or at least 3 days of hospital investigation. The B group included patients presenting with fever persisting for more than 3 weeks with no established diagnosis after 1 week of hospital investigation. The general conditions, etiologies, definite diagnosis times, and diagnostic methods of the two groups were compared. Results: There were no significant differences in the general conditions, etiologies, definite diagnosis times, and diagnostic methods between the Chinese revised diagnostic criteria and classical diagnostic criteria. Conclusion: Both the examined FUO diagnostic criteria are suitable for clinical practice in this region. Keywords: fever of unknown origin, diagnostic criteria, comparison, drug design&nbsp
