Opis:
The increasingly competitive nature of maritime freight transport has stimulated carriers to improve efficiency and lower costs. The industry has gradually matured, and it has recently become the case that the larger a carrier is, the more competitive advantage it has. Therefore, carriers form strategic alliances to collaborate with each other so that they can reduce their operational costs due to economies of scale. At the same time, such alliances allow carriers to improve the quality of their service by increasing their network coverage. Although carriers collaborate to improve their operational efficiency, they compete with each other simultaneously. In other words, a game of coopetition among carriers has developed in international maritime freight transport in recent years. In this study, we propose a theoretical framework for characterizing coopetition in international maritime shipping and investigating how carriers can manage their business models. Empirical studies, together with salient analytical results, are presented and discussed.

Opis:
The failure behaviors of many real-life systems are very complex and sequence-dependent, and can be modeled by highly-coupled dynamic fault trees (DFTs). Existing approaches for solving DFTs, such as Markov state-space-based or inclusion-exclusion based methods all have their disadvantages. They either suffer from the problem of state space explosion or are subjected to the combination explosion. Additionally, Markov-based approaches become unavailable when components follow non-exponential time-to-failure distributions which prevail in real-life systems. To overcome shortcomings of the methods mentioned above, SFRs (Sequence Failure Regions)-Based numerical simulation approach is first proposed. The proposed method is applicable for a generalized cut sequence as well as highly-coupled DFTs modeling non-repairable systems with arbitrary time-to-failure distributed components. The results of the validation example indicate the reasonability of our proposed approach.
Zachowania uszkodzeniowe wielu działających w rzeczywistości układów są bardzo złożone i zależą od sekwencji w jakiej występują uszkodzenia. Zachowania takie można modelować za pomocą silnie sprzężonych dynamicznych drzew błędów (DFT). Istniejące podejścia do rozwiązywania DFT, takie jak metody markowowskie oparte na pojęciu przestrzeni stanów i metody oparte na zasadzie włączeń i wyłączeń mają swoje ograniczenia:albo borykają się z problemem eksplozji przestrzeni stanów albo są narażone na eksplozję kombinatoryczną. Dodatkowo, podejścia markowowskie stają się niedostępne, gdy elementy składowe mają niewykładnicze rozkłady czasu do uszkodzenia, co ma miejsce w przeważającej części układów spotykanych w rzeczywistości. Aby przezwyciężyć mankamenty powyższych metod, zaproponowano metodę symulacji numerycznej opartą na pojęciu zakresów uszkodzeń sekwencyjnych (sequence failure regions, SFR). Proponowana metoda znajduje zastosowanie w modelowaniu systemów nienaprawialnych o elementach, które charakteryzuje arbitralnie przyjęty rozkład czasu do uszkodzenia. Metodę można stosować w modelowaniu opartym zarówno na uogólnionej sekwencji niezdatności (generalizedcut sequence), jak również silnie sprzężonych DFT. Wyniki uzyskane w przedstawionym przykładzie potwierdzają zasadność proponowanego przez nas podejścia.

Opis:
Detecting genetic association models between single nucleotide polymorphisms (SNPs) in various disease-related genes can help to understand susceptibility to disease. Statistical tools have been widely used to detect significant genetic association models, according to their related statistical values, including odds ratio (OR), chi-square test (χ2), p-value, etc. However, the high number of computations entailed in such operations may limit the capacity of such statistical tools to detect high-order genetic associations. In this study, we propose lsGA algorithm, a genetic algorithm based on local search method, to detect significant genetic association models amongst large numbers of SNP combinations. We used two disease models to simulate the large data sets considering the minor allele frequency (MAF), number of SNPs, and number of samples. The three-order epistasis models were evaluated by chi-square test (χ2) to evaluate the significance (P-value < 0.05). Analysis results showed that lsGA provided higher chi-square test values than that of GA. Simple linear regression indicated that lsGA provides a significant advantage over GA, providing the highest β values and significant p-value.

Opis:
Hylocereus undatus flower is commonly used as food or for medicinal purposes in south China. To study its antioxidant activity and mechanism we used antioxidant and chemical assays to compare two commercial samples from different locations (Shenjing, Qixing). The difference in antioxidant levels corresponded with differences in chemical content (including total phenolics, total flavonoids, kaempferol and quercetin) between Shenjing and Qixing. The antioxidant ability of H. undatus flower seems attributable to total phenolics (mainly total flavonoids). Kaempferol is one of the main bioactive components. H. undatus flower exerts its antioxidant effects through metal chelation and radical scavenging via hydrogen atom (H•) and electron (e) donation.

Opis:
The flow softening behaviors of a nickel-based superalloy with o phase are investigated by hot compression tests over wide ranges of deformation temperature and strain rate. Electron backscattered diffraction (EBSD). optical microscopy (OM), and scanning electron microscopy (SEM) are employed to study the flow softening mechanisms of the studied superalloy. It is found that the flow softening behaviors of the studied superalloy are sensitive to deformation temperature and strain rate. At high strain rate and low deformation temperature, the obvious flow softening behaviors occur. With the increase of deformation temperature or decrease of strain rate, the flow softening degree becomes weaken. At high strain rate (1s-1), the flow softening is mostly induced by the plastic deformation heating and flow localization. However, at low strain rate domains (0.001-0.01s-1), the effects of deformation heating on flow softening are slight. Moreover, the flow softening at low strain rates is mainly induced by the discontinuous dynamic recrystallization and the dissolution of 6 phase (Ni3Nb).

Opis:
This paper studies the tracking and almost disturbance decoupling problem of nonlinear systems with uncertainties, based on the feedback linearization approach. The main contribution of this study is to construct a controller, under appropriate conditions, such that the resulting closed-loop system is valid for any initial condition and bounded tracking signal with the following characteristics: input-to-state stability with respect to disturbance inputs and almost disturbance decoupling, i.e., the influence of disturbances on the L2 norm of the output tracking error can be arbitrarily attenuated by changing some adjustable parameters. Two examples, which cannot be solved by the first paper on the almost disturbance decoupling problem, are proposed in this paper to exploit the fact that the tracking and the almost disturbance decoupling performances are easily achieved by the proposed approach. In order to demonstrate the practical applicability, the paper has investigated the AMIRA ball and beam system.

Opis:
Canine mammary tumors are the most common neoplasms in intact female dogs. The surgery cannot always solve the problem, chemotherapy are recommend to these patients. However, chemotherapy could always fail because of multidrug resistance (MDR). Through stepwise increasing 5-Fluorouracil (5-FU) concentration in the culture medium, a 5-FU-resistant canine mammary tumor cell line CMT7364/5-FU was established to disclose the molecular mechanism of the drug resistance. Cell morphology, cell sensitivity to drugs, growth curves, expression of proteins, and chemo-sensitivity in vivo were compared between the parental cell line and resistant cell line. As compared it to its parental cell line (CMT7364), CMT7364/5-FU showed different morphology, cross-resistant to other chemo-drugs and a prolonged population doubling time (PDT). The drug efflux pump proteins (ABCB1 and ABCG2) in CMT7364/5-FU were up-regulated. In vivo, the similar result revealed that CMT7364/5-FU cell line was more resistant to 5-FU. In conclusion, a 5-FU-resistant canine mammary tumor cell line (CMT7364/5-FU) was successfully established, it can serve as a good model for researching the mechanism of MDR and screening effective agents to reverse drug resistance.

Opis:
The enzyme strictosidine synthase (STR, EC: 4.3.3.2) plays a key role in the biosynthetic pathway of terpenoid indole alkaloid (TIA). It catalyzes the condensation of the tryptamine and secologanin to form 3α(S)-strictosidine, which is the common precursor of all TIAs. In this paper, a STR gene designated as DoSTR (GenBank: KX068707) was first cloned and characterized from Dendrobium officinale with rapid amplified cDNA ends method (RACE). DoSTR has a length of 1380bp with 1179bp open reading frame encoding 392 amino acids. BlastP analyses showed that its amino acid sequence was classified into Str_synth superfamily. qRT-PCR showed that DoSTR was expressed in all tissues tested, with a significantly higher level in flower and the lowest in stem. Four different treatments with MeJA, SA, ABA and AgNO₃, respectively, could induce the DoSTR expression to a different extent. And the effect of MeJA was the most obvious and transcript level of DoSTR induced by MeJA was 20.7 times greater than that of control at 48 hours after treatment. Furthermore, it was found that DoSTR was localized in vacuole through transient expression in tobacco. The characterization and expression of DoSTR can help in further studying the role of DoSTR in the biosynthesis of TIAs in D. officinale. This study may throw light on the alkaloid biosynthesis pathway of D. officinale.

Opis:
A novel data knowledge representation with the combination of structure learning ability of preprocessed collaborative fuzzy clustering and fuzzy expert knowledge of TakagiSugeno-Kang type model is presented in this paper. The proposed method divides a huge dataset into two or more subsets of dataset. The subsets of dataset interact with each other through a collaborative mechanism in order to find some similar properties within eachother. The proposed method is useful in dealing with big data issues since it divides a huge dataset into subsets of dataset and finds common features among the subsets. The salient feature of the proposed method is that it uses a small subset of dataset and some common features instead of using the entire dataset and all the features. Before interactions among subsets of the dataset, the proposed method applies a mapping technique for granules of data and centroid of clusters. The proposed method uses information of only half or less/more than the half of the data patterns for the training process, and it provides an accurate and robust model, whereas the other existing methods use the entire information of the data patterns. Simulation results show the proposed method performs better than existing methods on some benchmark problems.

Hydrophobic surgical forceps of end-effectors for laparoscopic operations or minimally invasive surgery were developed through powder injection molding (PIM) and surface treatment. Processing conditions for mixing, debinding, and sintering were investigated to produce defect-free components. An optimum solid loading was determined by torque rheometry experiments. The optimized processing conditions for debinding and sintering were designed through the measurement of weight loss and shrinkage behavior by thermogravimetric analysis and dilatometry experiments. After producing the surgical forceps based on the optimized processing conditions via PIM, surface treatment was carried out to generate the hydrophobic structure on the surface.
