Is playing-as-downloading feasible in an eMule P2P file sharing system?

Peer-to-peer (P2P) swarm technologies have been shown to be very efficient for large scale content distribution systems, such as the well-known BitTorrent and eMule applications. However, these systems have been designed for generic file sharing with little consideration of media streaming support, and the user cannot start a movie playback before it is completely downloaded. The playing-as-downloading capability would be particularly useful for a downloading peer to evaluate if a movie is valuable to be downloaded, and it could also help the P2P content distribution system to locate and eliminate the polluted contents. In this paper we address this issue by introducing a new algorithm, wish driven chunk distribution (WDCD), which enables the P2P file sharing system to support the video-on-demand (VOD) function while keeping the P2P native downloading speed. A new parameter named next-play-frequency is added to the content chunk to strike a replication balance between downloading and streaming requests. We modify the eMule as the test bed by adding the WDCD algorithm and then verify the prototype implementation by experiments. The experimental results show that the proposed algorithm can keep the high downloading throughput performance of the eMule system with a good playing-as-downloading function.
Paracrine Unpaired Signaling through the JAK/STAT Pathway Controls Self-renewal and Lineage Differentiation of Drosophila Intestinal Stem Cells

Drosophila and mammalian intestinal stem cells (ISCs) share similarities in their regulatory mechanisms, with both requiring Wingless (Wg)/Wnt signaling for their self-renewal, although additional regulatory mechanisms are largely unknown. Here we report the identification of Unpaired as another paracrine signal from the muscular niche, which activates a canonical JAK/STAT signaling cascade in Drosophila ISCs to regulate ISC self-renewal and differentiation. We show that compromised JAK signaling causes ISC quiescence and loss, whereas signaling overactivation produces extra ISC-like and progenitor cells. Simultaneous disruption or activation of both JAK and Wg signaling in ISCs results in a stronger ISC loss or a greater expansion of ISC-like cells, respectively, than by altering either pathway alone, indicating that the two pathways function in parallel. Furthermore, we show that loss of JAK signaling causes blockage of enteroblast differentiation and reduced JAK signaling preferentially affects enteroendocrine (ee) cell differentiation. Conversely, JAK overactivation produces extra differentiated cells, especially ee cells. Together with the functional analysis with Notch (N), we suggest two separate roles of JAK/STAT signaling in Drosophila ISC lineages: it functions upstream of N, in parallel and cooperatively with Wg signaling to control ISC self-renewal; it also antagonizes with N activity to control the binary fate choice of intestinal progenitor cells.
Measurement of R at VEPP-2000*

The new e~+e~- storage ring, VEPP-2000, is being commissioned at Budker Institute of Nuclear Physics, Novosibirsk. Measurement of the total cross section e~+e~-→hadrons in the whole VEPP-2000 energy range is one of the main goals of the new experiments. We discuss the goals of the measurement and the expected systematic errors.
Recent results on hadron spectroscopy from BES

The BES-III Detector is a very versatile multipurpose device located at the Institute of High Energy Physics (IHEP) in Beijing, China. Concerning the physics program it ties stringently up to the past BES and BES-II experiments. Since start of the data taking in the middle of 2008 the accumulated dataset of 200·10~6 J/ψ events and 100·10~6 ψ' events already exceeds the world data on these resonances. In addition to studies of the charmonium systems the data offers great opportunity for investigations in the light hadron sector. In detail it will be reported about the con_rmation of the enhancement in pp invariant mass in radiative J/ψ decays, the search for decays Y(2175)→K*~0K*~0, observation of a charged k± in K±π~0 and observation of a new excited baryon N*(2065) decaying to p_0 and charged conjugate. The first result is based on data taken BES-II and BES-III, the latter three on data collected by BES-II only.
Establishment of an ELISA to Detect Kaposi's Sarcoma-associated Herpesvirus Using Recombinant ORF73*

Kaposi's sarcoma-associated herpesvirus (KSHV) is causally related to Kaposi's sarcoma (KS), primary effusion lymphoma (PEL) and a proportion of cases of multicentric Castleman's disease (MCD).The ORF73 protein was cloned into pQE80L-orf73 and expressed in E.coli and purified.The expressed recombinant ORF73 was identified by sodium dodecyl sulfatepolyacrylamide gel electrophoresis (SDS-PAGE).A protein of about 27 kDa was expressed as expected.Western Blotting showed that the purified recombinant ORF73 reacted with KSHV positive serum.The immunogenicity of the recombinant ORF73 was further analysed by ELISA and the optimal conditions were determined.The ORF73 ELISA was used to compare the KSHV seroprevalence between Hubei and Xinjiang Han people.The Han people in Xinjiang have significantly higher KSHV seroprevalence than their counterparts in Hubei (6.7% vs 2.9%, P = 0.005).
Molecular characterization of two novel esterase genes from carmine spider mite, Tetranychus cinnabarinus (Acarina: Tetranychidae)

Two novel esterase complementary DNAs were identified and cloned from the insecticide-susceptible strain of Tetranychus cinnabarinus (Boisduval) (Acarina: Tetranychidae), which were designated as TCE1 and TCE2, respectively. The cDNA of TCEI gene contained an open reading frame (ORF) of 1701 bp encoding 567 amino acids, and a predicted molecular weight of 62.75 kDa, the cDNA of TCE2 contained an ORF of 1680 bp encoding 560 amino acids, and a predicted molecular weight of 63.14 kDa. TCE1 and TCE2 were submitted to GenBank, accession number EU130461 and EU130462. The well-conserved sequence motif, GXSXG, used as a signature pattern in the esterase family are present in both TCE1 and TCE2 (GQSAG in TCE1, whereas GESAG in TCE2), indicating that these two genes are predicted to be esterases. Comparison of the deduced amino acid sequence with the published mite esterase sequence coming from Boophilus microplus showed that TCE1 shares 33.98% identity and TCE2 shares 33.46% identity. TCE1 and TCE2 share 46.4% identity. Quantitative real-time polymerase chain reaction revealed that expression level of the TCE2 gene was relatively higher than that of the TCE1 in all instars examined except the protonymph, and the expression level of these two esterase genes in adults of T. cinnabarinus was significantly higher than that in any other instars, respectively. T. cinnabarinus is an important agricultural mite pest and esterases are important in the metabolisms of insects and mites; the genomic information obtained in this study will contribute to esterase molecular biological study on mite pest species.
Quantitative Trait Loci Mapping for Leaf Length and Leaf Width in Rice cv. IR64 Derived Lines

The present study was conducted to identify quantitative trait loci (QTLs) for leaf size traits in IR64 introgression lines (INLs). For this purpose, selected F_2 populations derived from crosses between recurrent parent IR64 and its derived INLs, unique for leaf length and leaf width, were used to confirm QTLs. A total of eight QTLs, mapped on three chromosomes, were identified for the four leaf size traits in six F_2 populations. A QTL for leaf length, qLLnpt-1, in HKL69 was identified around simple sequence repeat (SSR) marker RM3709 on chromosome 1. Two QTLs for flag leaf length, qFLLnpt-2 and qFLLnpt-4, in HFG39 were indentified on chromosomes 2 and 4, respectively. For flag leaf width, a QTL, qFLWnpt-4, in HFG39 was identified around RM17483 on chromosome 4. While another QTL for flag leaf width, qFLWnpt-1, in HFG27 was identified around RM3252 on chromosome 1. A QTL for leaf width, qLWnpt-2, in HKL75 was identified around RM7451 on chromosome 2. For leaf width, two QTLs, qLWnpt-4a, qLWnpt-4b, in HKL48 and HKL99 were identified around RM7208 and RM6909, respectively on chromosome 4. Results from this study suggest the possibilities to use marker-assisted selection and pyramiding these QTLs to improve rice water productivity.
Role of Ca~2+ on Growth of Brassica campestris L. and B. juncea (L.) Czern & Coss under Na+ Stress

Root and shoot growth of Brassica campestris L. and B. juncea increased significantly (P > 0.01) with enhanced Ca~(2+) treatment along with 60 mM NaCI in the root medium. The maximum fresh mass of shoot and root in B.juncea was recorded at 10 mM Ca~(2+) concentration. The relative growth rate of shoot of both species reached its maximum at 8 mM of Ca~(2+) concentration. Average rate of Ca~(2+) intake (I_ca) was higher in B. juncea than B. campestris. In B. juncea, the average transport of Ca~(2+) to shoot increased by 19%, 38%, 119%, 125% and 169% compared with the control. Furthermore specific utilization rate of Ca~(2+) was higher in B. juncea than B. campestris. In B. campestris it increased by 9%, 32%, 41% and 59% at 4, 6, 8, and 10 mM of calcium in comparison to 2 mM Ca~(2+) treatment. At 4, 6, 8 and 10 mM of Ca~(2+) application, the increase in the leaf area ratio was 10, 17, 23 and 30%, respectively. In the shoot and root portions of B. campestris and B. juncea, Ca~(2+) had a linear relationship with potassium and sulfur, whereas it was in antagonism with sodium ion.
Formation of the Fertilization Pore during Oogenesis of the Fern Ceratopteris thalictroides

The development of the fertilization pore during oogenesis of the fern Ceratopteris thalictroides was followed using transmission electron microscopy. The newly formed egg is appressed closely to the adjacent cells. There are well-developed plasmodesmata between the egg and the ventral canal cell, but none between the egg and the jacket cells of the archegonium. During maturation, a separation cavity is formed around the egg. However, a pore region persistently connects the egg and the ventral canal cell. The extra egg membrane is formed by deposition of sheets of endoplasmic reticulum (ER), but no ER is deposited on the inner surface of the pore region. Thus, a fertilization pore, covered by a layer of plasmalemma, is formed. The ventral canal cell undoubtedly participates the formation of the fertilization pore, probably by absorbing the sheets of ER beneath the pore region. The functional significance of the ventral canal cell in formation of the fertilization pore is discussed. The features of the mature egg include that abundant concentric membranes and osmiophilic vesicles occur in the cytoplasm of the mature egg. The initial, round nucleus of the egg eventually becomes cup-shaped. This investigation gives some new insights about the cells participating oogenesis in ferns.
Effect of Different Factors on Nitrogen Removal Rate in Constructed Wetlands

Factors affecting total nitrogen (TN) removal rates in constructed wetland were investigated by intermittent operation in the subsurface flow (SSF) constructed wetland system. The results demonstrated that removal rates of TN increased with the rising of TN pollution load (1.40 - 12.40 g/m~2) when the retention time was determined by 60% TN removal efficiency (n = 180, p > 0.05) in SSF wetlands. The maximum TN removal rate was 1.71 g/( m~2 d) in SSF Phragmites australis - soil - slag system. TN removal rates were affected by total phosphorus load in case of higher TN load. TN removal rates in SSF Phragmites australis wetlands were greater than that in SSF Calamagrostis angustifolia wetlands at the same experimental cycle. Effect of wetland substrates on TN removal rates varied with the pollutants loading in SSF constructed wetland system, plant species and plant - growing period.
Optical properties of highly photosensitive hybrid sol-gel films

A new organic-inorganic hybrid material, which shows photo-induced reduction of refractive index as well as volume contraction, is prepared using a sol-gel method. This material is coated on a Si substrate by spin-coating to manufacture film. After irradiated by ultraviolet (UV) light with a deuterium lamp for 5 h, the thickness of film decreases largely by 55%, and the refractive index of film changes from 1.484 to 1.445 at 550 nm. The film's optical thickness exhibits an exponential change with the increasing irradiation time. Futhermore, the photo-patternning of the organic-inorganic hybrid film without any further process (wet etching and thermal curing) is performed utilizing the volume contraction on UV-light irradiation. This film has potential applications for fabrication of patterned filter array and apodizing filter by direct light writing, and also demonstrates good temperature stability and immunity to visible light exposure.

Investigation on LaF3/porous silicon system for photonic application

We present the investigation on LaF_3/porous silicon (PS) system that has properties of both the materials to be applied in photonics. Epilayers of LaF_3 are grown on PS under different anodization conditions using electron-beam evaporation (EBE). The characteristics of the LaF_3/PS system are analyzed by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), and photoluminescence (PL). XRD confirms the polycrystalline nature of the LaF3 film. Nearly stoichiometric growth of LaF_3 on PS is established by EDX. Such a thin LaF_3 layer grown on PS leads to a good enhancement of PL yield of PS. But with the increasing thickness of LaF_3 layer, PL intensity of PS is found to decrease along with a small blue-shift.
Modified Classical Over Barrier Model for Multi-Charged Ion in Collisions with Multiple Electron Target at Energies Below 1 keV/u

Charge transfer cross sections for Kr~(q+) with Ne are calculated quantitatively by using modified classical over barrier model in order to clarify energy dependence of charge transfer cross sections in low energy region. Essential of this model is taking the induced dipole potential into consideration. As a result, this calculation can reproduce systematic energy dependence of experimental results. This suggests that the bending trajectory of the projectile due to an induced dipole potential should be considered to describe pictures of collisions at low energy regime below 1 keV/u.
Surface Modification of Poly Vinyl Chloride (PVC) Using Low Pressure Argon and Oxygen Plasma

In this study, commercial poly vinyl chloride (PVC) films were treated by oxygen and argon plasmas in a cylindrical glass tube which was surrounded by a DC variable magnetic field, with different sample positions in the plasma reactor and also different exposure durations. Effects of the plasma treatment on the hydrophilic properties of the films were studied by measuring the water drop contact angle on the surface of the samples. The surface topography of the untreated and plasma treated films was analyzed and compared by atomic force microscopy (AFM). The optical characteristic changes in treated samples were investigated using reflective spectrophotometry. Also, the chemical changes which appeared on the surface of the samples were investigated using Fourier transform infrared spectroscopy (FTIR). The results show that the plasma treated PVC becomes more hydrophilic with an enhanced wettability. A sharp decrease in the water contact angle may also be a consequence of the surface texturization. The aging effect on wettability of the samples was also investigated. The results show that the effect of oxygen plasma on the surface properties of the samples is more pronounced compared with that of argon plasma.
AMACR is associated with advanced pathologic risk factors in sporadic colorectal adenomas

AIM: To analyze a-methylacyl CoA racemase (AMACR) expression in relation to various dysplasia phenotypes and clinicopathological parameters of sporadic colorectal adenomas. METHODS: Fifty-five cases of sporadic colorectal adenomas were categorized according to the Vienna classification for Gastrointestinal Neoplasia. These corresponded to a total of 98 different intra-lesion microscopic fields that were further independently assigned a histological grade based on the old nomenclature (mild, moderate, severe dyplasia and carcinoma in situ). AMACR expression was evaluated by immunohistochemistry and statistical analysis was performed to investigate possible associations with various clinicopathologic parameters of adenomas i.e. gender, age, localization, grade of dysplasia, size and configuration. RESULTS: Patient age ranged from 41 to 84 years (mean 65 ± 13.2 years); 37 patients were males and 18 were females. Adenomas ranged in size between 0.5 and 30 cm (mean 2 ± 1.3 cm), including 18 tubular, 16 villous, 20 mixed or tubulovillous, and 1 giant sessile villous adenoma. AMACR expression was observed in 3 out of 16 (18.8%) of low-grade vs 23 out of 35 (62.8%) of high-grade lesions (P = 0.002). Most adenomas exhibiting high grade dysplasia with in situ carcinoma-like areas stained positive for AMACR (15/17 or 88.2%) as compared to adenomas with high grade dysplasia which contained severe dysplasia-like foci (6/15 or 40%), (P = 0.005). In AMACR positive adenomas featuring severe dysplasia-like or in situ carcinoma-like areas, AMACR staining was not necessarily observed in the in situ component. Positivity in intra-lesion of mild, moderate or severe dysplasia-like foci was more often encountered in adenomas harboring in situ, intramucosal or infiltrative carcinoma [21/33 (63.6%) vs 9/40 (22.5%), P > 0.001]. Strong AMACR expression was found in 11 out of 17 villous adenomas, but in only 1 out of 18 tubular lesions (P = 0.005). Larger lesions, i.e. < 1 cm stained more frequently for AMACR than smaller ones [27/45 (60%) vs 2/10 (20%), P = 0.02]. Overall, AMACR expression was associated with the grade of dysplasia, as well as with the size and configuration of adenomas, i.e. the consensus risk factors applied to colorectal adenoma patient surveillance. CONCLUSION: It may be worthy to further evaluate the possible use of AMACR as an additional risk factor for the assessment of colorectal adenoma patients.
Efficacy of rituximab in gastric diffuse large B celllymphoma patients

AIM: To evaluate retrospectively the efficacy of rituximab plus chemotherapy in gastric diffuse large B cell lymphoma (DLBCL). METHODS: Sixty patients (median age: 58 years) with histologically confirmed gastric DLBCL treated at four Italian institutions between 2000 and 2007, were included in this analysis. Patients were selected by stage(I -IV, Lugano staging system), European Cooperative Oncology Group performance status (0-2) and treatment strategies. Treatment strategies were chemotherapy alone (group A, n = 30) [scheduled as cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) and CHOP-like], and chemotherapy combined with rituximab (group B, n = 30). The primary end point of the study was complete response (CR) rate; the secondary end points were disease-free survival (DFS) at 5 years and overall survival (OS). RESULTS: Median follow-up was 62 mo (range: 31-102 mo). We observed a significant difference between the two groups (A vs B) in terms of CR [76.6% (23/30) vs 100%, P = 0.04) and DFS at 5 years [73.3% (22/30) vs 100%, P = 0.03). To date, 19 group A (63.3%) patients are alive and 11 have died, while all group B patients are alive. No significant differences in toxicity were observed between the two groups. CONCLUSION: Rituximab in combination with chemotherapy improves CR rate, DFS and OS. Further prospective trials are needed to confirm our results.
Two-phase TOPSIS of uncertain multi-attribute group decision-making

To solve the uncertain multi-attribute group decisionmaking of unknown attribute weights, three optimal models are built to decide the corresponding ideal solution weights, standard deviation weights and mean deviation weights. The comprehensive attribute weights are gotten through the product of the above three kinds of weights. And each decision maker's weighted decision matrices are also received by using the integrated attribute weights. The closeness degrees are also gotten by use of technique for order preference by similarity to ideal solution (TOPSIS) through dealing with the weighted decision matrices. At the same time the group decision matrix and weighted group decision matrix are gotten by using each decision-maker's closeness degree to every project. Then the vertical TOPSIS method is used to calculate the closeness degree of each project. So these projects can be ranked according to their values of the closeness degree. The process of the method is also given step by step. Finally, a numerical example demonstrates the feasibility and effectiveness of the approach.
Gas-hydrate formation, agglomeration and inhibition in oil-based drilling fluids for deep-water drilling

One of the main challenges in deep-water drilling is gas-hydrate plugs, which make the drilling unsafe. Some oil-based drilling fluids (OBDF) that would be used for deep-water drilling in the South China Sea were tested to investigate the characteristics of gas-hydrate formation, agglomeration and inhibition by an experimental system under the temperature of 4 ℃ and pressure of 20 MPa, which would be similar to the case of 2000 m water depth. The results validate the hydrate shell formation model and show that the water cut can greatly influence hydrate formation and agglomeration behaviors in the OBDF. The oleophobic effect enhanced by hydrate shell formation which weakens or destroys the interfacial films effect and the hydrophilic effect are the dominant agglomeration mechanism of hydrate particles. The formation of gas hydrates in OBDF is easier and quicker than in water-based drilling fluids in deep-water conditions of low temperature and high pressure because the former is a W/O dispersive emulsion which means much more gas-water interfaces and nucleation sites than the later. Higher ethylene glycol concentrations can inhibit the formation of gas hydrates and to some extent also act as an anti-agglomerant to inhibit hydrates agglomeration in the OBDF
