Development of Unity3D Network Functionality on Android
Shangguan Dayan,Huang Xinyuan 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.2
In the field of Mobile Terminal (MT), Unity3D game engine has displayed outstanding rendering power and highly aggregated script editing function while in practice the network function of Unity3D has not been fully developed yet. This paper, based on the comparison with traditional network technology, proposed to invoke Java to create a WIFI Local Area Network (WLAN), in which Unity network view component and remote procedure call (RPC) are employed to synchronize data and images on both ends of the network, thus developing a Unity online game. Finally the author of this paper has designed an online Unity3D chess game based on Android mobile platform. The results indicate that the invocation of Java has made up the deficiency of Unity network while RPC, as a reliable, free and economical method in the network transmission displays great adaptability. The combination of Java and RPC has proved to be a simple but an effective way to develop mobile online game.

Previously, we have demonstrated that the seeds of Euterpe oleracia Mart. (açaí) are rich in polyphenols with antihypertensive and antioxidant properties. This study evaluated the renal protective effects of the hydroalcoholic extract obtained from the seeds of açaí (ASE) fruits in two-kidney, one-clip (2K1C) renovascular hypertension. Young male Wistar rats were used to obtain 2K1C and sham groups. Animals received ASE (200 mg/(kg·day) in drinking water) or vehicle for 40 days. We evaluated serum and urinary parameters, renal structural changes, and oxidative status. The increase in systolic blood pressure of the 2K1C group was accompanied by a decrease in left kidney volume and number of glomeruli, as well as an increase in glomerular volume and collagen deposition. ASE prevented the alterations of these parameters, except the reduced kidney volume. Serum levels of urea and creatinine and urinary protein excretion were increased in the 2K1C group and treatment with ASE improved all these functional parameters. The increased oxidative damage in the 2K1C group, assessed by lipid and protein oxidation, was prevented by ASE. The nitrite content and both expression and activity of antioxidant enzymes (superoxide dismutase-1, catalase, and glutathione peroxidase) were lower in the 2K1C group and restored by ASE. ASE substantially reduced renal injury and prevented renal dysfunction in 2K1C rats probably through its antihypertensive and antioxidant effects, providing a natural resource for treatment and prevention of renovascular hypertension-related abnormalities.

A common concern regarding cooperative spectrum sensing (CSS) schemes is the occupied bandwidth and the energy consumption during the transmissions of sensing information to the fusion center over the reporting control channels. This concern is intensified if the number of cooperating secondary users in the network is large. This article presents a new fusion strategy for a CSS scheme, aiming at increasing the energy efficiency of a recently proposed bandwidth-efficient fusion scheme. Analytical results and computational simulations unveil a high increase in energy efficiency when compared with the original approach, yet achieving better performances in some situations, and lower implementation complexity.

This study investigated the protective effect of a Vitis vinifera L. grape skin extract (ACH09) on blood pressure, lipid profile, and oxidative status in spontaneously hypertensive rats (SHR). Systolic blood pressure (SBP), total cholesterol, triglyceride, and glucose levels, as well as oxidative damage and antioxidant activity in the plasma and kidney, were evaluated in four experimental groups: control Wistar rats (W-C) and SHR-C that received water, and Wistar rats and SHR treated with ACH09 (200 mg/kg/d) in drinking water for 12 weeks (W-ACH09 and SHR-ACH09, respectively). SBP increased in the SHR group compared with the W groups and the treatment with ACH09 prevented the development of hypertension. Plasma triglyceride and total cholesterol levels increased in SHR compared with W-C rats; these changes prevented by treatment with ACH09. Glucose levels did not differ between the groups. The SHR group had increased oxidative damage in plasma, as expressed by 2-thiobarbituric acid reactive substances (TBARS) levels, and this prevented by ACH09. Levels of TBARS in the kidneys were lower in the SHR-ACH09 group than in the SHR-C group. Further, ACH09 increased the superoxide dismutase activity in both the plasma and kidneys of both SHR and Wistar rats. These results suggest that ACH09 is protective against disruption of blood pressures, oxidant status, and lipid profile in SHR, and provide important evidence on the benefits of ACH09 on hypertension and associated cardiovascular complications.

<▼1><P/><P>We report a mesogenic compound which introduces nematic liquid crystal (LC) ordering into the benzothienobenzothiophene (BTBT) family of LCs, creating a new class of LC semiconducting materials which respond in a facile way to anisotropic surfaces, and can, thereby, be effectively processed into highly oriented monodomains. Measurement on these domains of the electrical conductivity, with in situ monitoring of domain quality and orientation using LC birefringence textures in electroded cells, brings a new era of precision and reliability to the determination of anisotropic carrier mobility in LC semiconductors.</P></▼1><▼2><P>The synthetic LC OSC is uniaxial planar aligned on the rubbed polymer substrate due to the long-range ordering characteristic of the nematic phase directly observed by polarized optical microscopy.</P></▼2>

Objectives: To evaluate and compare light-transmittance in dental tissues and dental composite restorations using the incremental double-layer technique with varying layer thickness. Materials and Methods: B1-colored natural teeth slabs were compared to dental restoration build-ups with A2D and B1E-colored nanofilled, supra-nanofilled, microfilled, and microhybrid composites. The enamel layer varied from 0.3, 0.5, or 1.2 mm thick, and the dentin layer was varied to provide a standardized 3.7 mm overall sample thickness (n = 10). All increments were light-cured to $16J/cm^2$ with a multi-wave LED (Valo, Ultradent). Using a spectrophotometer, the samples were irradiated by an RGB laser beam. A voltmeter recorded the light output signal to calculate the light-transmittance through the specimens. The data were analyzed using 1-way analysis of variance followed by the post hoc Tukey's test (p = 0.05). Results: Mean light-transmittance observed at thicker final layers of enamel were significantly lower than those observed at thinner final layers. Within 1.2 mm final enamel resin layer (FERL) thickness, all composites were similar to the dental tissues, with exception of the nanofilled composite. However, within 0.5 mm FERL thickness, only the suprananofilled composite showed no difference from the dental tissues. Within 0.3 mm FERL thickness, none of the composites were similar to the dental tissues. Conclusions: The supra-nanofilled composite had the most similar light-transmittance pattern when compared to the natural teeth. However, for other composites, thicker FERL have a greater chance to match the light-transmittance of natural dental tissues.

Although there are several studies highlighting the best new product development(NPD) practices of Western firms, we know very little about NPD practices inemerging economies, which are widely expected to play an important role in theworld’s economic growth in the years to come. In particular, we focus here on theUnited Arab Emirates (UAE), which is an important gateway to the Middle East andAfrica. Understanding NPD practices in the UAE will be helpful not only for firms inthe UAE seeking to improve their NPD but also for Western firms interested inengaging in NPD in that region, in order for them to know what to expect from theirpotential partners from the UAE and how to align their NPD practices with those oftheir partners in that region. This paper presents a survey study highlighting majorstrategic, organizational and operational aspects of the NPD practices of firms in theUAE and identifying related challenges.

Purslane extract (PE) is derived from Portulaca oleracea L., a medicinal plant used in traditional medicine for its antidiabetic properties. This randomized, placebo-controlled clinical trial was designed to evaluate the efficacy and safety of PE in improving glucose control, blood pressure, and lipid profile in adults with type 2 diabetes mellitus (T2DM) treated with a single oral hypoglycemic agent at baseline. Subjects were randomized to treatment with three capsules of PE/day or a matched placebo. Change from baseline to the week 12 end-of-follow-up visit measures of glucose homeostasis, hemodynamics, and lipid profile was compared by treatment assignment. In addition, these measures were evaluated in a subgroup of ‘‘responders,’’ defined as patients whose week 12 HbA1c was lower than baseline values, regardless of treatment assignment. This group was further assessed in subgroups of baseline oral hypoglycemic treatment. A total of 63 participants were treated with either PE (n = 31, 11 females, mean age 52.4 ± 7.9 years) or matched placebo (n = 32, 11 females, mean age 58.3 ± 10.8 years). In the total cohort, systolic blood pressure declined significantly more in the PE group than the placebo group: -7.5 ± 5.0 versus -0.01 ± 0.3 mmHg, P < .0001. In the responders’ subgroup, HbA1c declined significantly more in the PE group than the placebo group: -0.8% ± 0.4% versus -0.6% ± 0.5%, P = .03. Few adverse events were reported. These were mild and did not differ by treatment assignment. PE appears to be a safe, adjunct treatment for T2DM, significantly reducing systolic blood pressure in the total cohort and HbA1c in the subgroup of responders.
