The topics of green supply chain management (GSCM) and corporate social responsibility (CSR) have attracted many research works as the sustainable economic model is growing. Most of the previous research on CSR and GSCM has focused on large enterprises and corporations. However, there are very few studies in Vietnam written about CSR and GSCM applications and their impact on firm performance, especially in small and medium-sized enterprises (SMEs). Therefore, this study was carried out to analyze the impact of CSR on firm performance of SMEs in Vietnam with the intermediaries of GSCM. The study was conducted using qualitative research methods, from previously related studies and based on the theory of CSR, GSCM, firm performance, and stakeholder theory. On that basis, the study points to research gaps that could be carried out in the future. Keywords: Corporate social responsibility, Green supply chain management, Firm performance, SMEs.

Disseminated intravascular coagulation is a complex and potentially lethal complication of malignancy, in which the fundamental abnormality is excessive activation of the coagulation system. It is a rare complication of melanoma which can be difficult to diagnose in some circumstances, leading to delay in treatment. Herein, we describe the first case of disseminated intravascular coagulation occurring in BRAF and NRAS-mutant metastatic melanoma, and systematically review the literature regarding disseminated intravascular coagulation in melanoma. This review summarizes the reported cases of disseminated intravascular coagulation in melanoma and those secondary to the novel treatment of melanoma, and explores the pathophysiology of disseminated intravascular coagulation in melanoma, highlighting the key role of expression of markers of coagulation and fibrinolysis in disseminated intravascular coagulation, as well as more widely in melanoma. Current limitations in the literature are also identified and discussed, particularly with respect to improving the management of this lethal complication. Disseminated intravascular coagulation is a rare complication of melanoma that typically portends poor prognosis.

Security is a major concern in wireless sensor network designing which suffers from many stringent hardware and software restrictions. It has attracted a large amount of attention from the research circle as security requirements became more and more indispensable in the Internet of Thing (IoT) evolution. An effective security mechanism is essential for deploying sensor networks. This paper proposes a security technique based on MAC behaviors for lightweight digital watermarking which aims to attain confidentiality and authentication for data. Embedded watermark values are constructed by information from MAC layer parameters which are simple to implement and resistant to attack. The numerical results and security analysis show proficiency of the proposed watermark scheme and evaluate the tradeoff between watermark detection probability and energy consumption of the network model.

Magnetic nanoparticles (MNPs) exhibiting superparamagnetic properties might generate large magnetic dipole–dipole interaction with electron spins in organic semiconductors (OSECs). This concept could be considered analogous to the effect of hyperfine interaction (HFI). In order to investigate this hypothesis, Fe3O4 MNPs are used as a dopant for generating random hyperfine-like magnetic fields in a HFI-dominant π-conjugated polymer host, poly(2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene) (MeH-PPV). The magnetoconductance (MC) response in organic light emitting diodes (OLEDs) made by MeH-PPV/MNP blends is used to estimate the effective hyperfine field in the blends. Firstly, we find that the shape of the MC response essentially remains the same regardless of the MNP concentration, which is attributed to the similar functionality between the nuclear spins and magnetic moments of the MNPs. Secondly, the width of the MC response increases with increasing MNP concentration. Magneto-optical Kerr effect (MOKE) experiments and micromagnetic simulation indicate that the additional increase of the MC width is associated with the magnetization of the blend. Finally, the MC broadening has the same temperature dependent trend as the magnetization of the MNPs where the unique effect of the MNPs in their superparamagnetic and ferromagnetic regimes on the MC response is observed. Magneto-photoinduced absorption (MPA) spectroscopy confirms that the MC broadening is not due to defects introduced by the MNPs but a result of their unique superparamagnetic behavior. Our study yields a new pathway for tuning OSECs’ magnetic functionality, which is essential for organic optoelectronic devices and magnetic sensor applications.

Energy-producing pathways, adenine nucleotide levels, oxidative stress response and Ca(2+) homeostasis were investigated in cybrid cells incorporating two pathogenic mitochondrial DNA point mutations, 3243A>G and 3302A>G in tRNA(Leu(UUR)), as well as Rho(0) cells and compared to their parental 143B osteosarcoma cell line. All cells suffering from a severe respiratory chain deficiency were able to proliferate as fast as controls. The major defect in oxidative phosphorylation was efficiently compensated by a rise in anaerobic glycolysis, so that the total ATP production rate was preserved. This enhancement of glycolysis was enabled by a considerable decrease of cellular total adenine nucleotide pools and a concomitant shift in the AMP+ADP/ATP ratios, while the energy charge potential was still in the normal range. Further important consequences were an increased production of superoxide which, however, was neither escorted by major changes in the antioxidative defence systems nor was it leading to substantial oxidative damage. Most interestingly, the lowered mitochondrial membrane potential led to a disturbed intramitochondrial calcium homeostasis, which most likely is a major pathomechanism in mitochondrial diseases.

The growth of 79% Bi2Fe4O9−21% Fe3O4 nanocomposite films on (100) LaAlO3 substrates using molecular beam epitaxy is reported. X-ray diffraction and field emission scanning electron microscopy confirmed that the nanocomposites consisted of an orthorhombic phase of lamellae Bi2Fe4O9 embedded in a face-centered-cubic (fcc) phase of a nanorod-like Fe3O4 matrix. Consequently, nanocomposite films exhibit a significant change of the Verwey transition temperature (TV) as the tailoring heteroepitaxial constraints along the vertical interfaces between the Fe3O4 and Bi2Fe4O9. A possible explanation for the peak at 260 K, referred to as the Neel temperature (TN), is that the magnetization curve is superimposed ferromagnetic Fe3O4 with antiferromagnetic Bi2Fe4O9 components.

A disseminated and progressive infection, penicilliosis marneffei is the third most common opportunistic infection in human immunodeficiency virus (HIV)-infected patients in certain parts of Southeast Asia. Penicillium marneffei is endemic in Southeast Asia and the southern part of China. Cases have been reported from both Eastern and Western countries. This review discusses the history, epidemiology, mycology, clinical manifestations, diagnosis, and treatment of penicilliosis marneffei, on the basis of 155 cases of the infection. About 80% of the patients are immunocompromised. P. marneffei can infect various organs, particularly the lung, liver, and skin. The most common clinical features include fever, weight loss, and anemia. The organism has been isolated most commonly from skin, blood, and bone marrow. Immunologic identification of fungal isolates can be done with exoantigen tests and immunohistochemical methods. Treatment of disseminated penicilliosis marneffei in HIV-infected patients with parenteral amphotericin B and itraconazole is relatively effective and safe.

The similarity search problem in streaming time series has become a hot research topic since such data arise in so many applications of various areas. In this problem, the fact that data streams are updated continuously as new data arrive in real time is a challenge due to expensive dimensionality reduction recomputation and index update costs. In this paper, adopting the same ideas of a delayed update policy and an incremental computation from IDC index (Incremental Discrete Fourier Transform(DFT) Computation --- Index) we propose a new approach for similarity search in streaming time series by using MP_C as dimensionality reduction method with the support of Skyline index. Our experiments show that our proposed approach for similarity search in streaming time series is more efficient than the IDC-Index in terms of pruning power, normalized CPU cost and recomputation and update time.

In this paper, we introduce a new time series dimensionality reduction method, MP_C (Middle points and Clipping). This method is performed by dividing time series into segments, some points in each segment being extracted and then these points are transformed into a sequence of bits. In our method, we choose the points in each segment by dividing a segment into sub-segments and the middle points of these sub-segments are selected. We can prove that MP_C satisfies the lower bounding condition and make MP_C indexable by showing that a time series compressed by MP_C can be indexed with the support of Skyline index. Our experiments show that our MP_C method is better than PAA in terms of tightness of lower bound and pruning power, and in similarity search, MP_C with the support of Skyline index performs faster than PAA based on traditional R*-tree.
