In this article, we consider the Parabolic Anderson model with constant initial condition, driven by a space-time homogeneous Gaussian noise, with general covariance function in time and spatial spectral measure satisfying Dalang’s condition. First, we prove that the solution(in the Skorohod sense) exists and is continuous in L^p(?). Then, we show that the solution has a modification whose sample paths are h?lder continuous in space and time,under the minimal condition on the spatial spectral measure of the noise(which is the same as the condition encountered in the case of the white noise in time). This improves similar results which were obtained in [6, 10] under more restrictive conditions, and with sub-optimal exponents for h?lder continuity.

AIm： To investigate the expression and activity of NAD（P）h quinone oxidoreductase 1 （NQO1） in human liver specimens obtained from patients with liver damage due to acetaminophen （APAP） overdose or primary biliary cirrhosis （PBC）. mEThODS： NQOt activity was determined in cytosol from normal, APAP and PBC liver specimens. Western blot and immunohistochemical staining were used to determine patterns of NQO1 expression using a specific antibody against NQO1. RESULTS： NQO1 protein was very low in normal human livers. In both APAP and PBC livers, there was strong induction of NQO1 protein levels on Western blot. Correspondingly, significant up-regulation of enzyme activity （16- and 22-fold, P〈0.05） was also observed in APAP and PBC livers, respectively. Immunohistochemical analysis highlighted injury-specific patterns of NQO1 staining in both APAP and PBC livers. CONCLUSION： These data demonstrate that NQO1 protein and activity are markedly induced in human livers during both APAP overdose and PBC. Up-regulation of this cytoprotective enzyme may represent an adaptive stress response to limit further disease progression by detoxifying reactive species.

Parenteral nutrition associated liver disease (PNALD) is a significant complication in infants receiving long-term parenteral nutrition (PN). Chronic administration of PN has been associated with its development. Our purpose is to characterize our incidence of PNALD over an extended period and identify risk factors for its development, including administration of soybean-based injectable lipid emulsions (ILEs) as we transit to novel ILEs in our practice. Infants receiving 30 days or more of PN were included. PNALD was defined as a direct bilirubin ≥ 2 mg/dL. Data collected included: patient demographics, clinical and enteral feeding characteristics. Macronutrient intake was recorded using these cut-offs: glucose infusion rate (GIR) of ≤14 mg/kg/min or above, protein doses of ≤3 g/kg/day or above and lipid doses of ≤2 g/kg/day or above. A total of 349 infants were included, with an annual incidence of PNALD ranging between 34% - mily:Verdana;">54%. Infants with PNALD were younger by gestation (27 vs. 29.5 weeks) and smaller by birthweight (900 vs. 1248 grams). Sepsis, GI disease including necrotizing enterocolitis and bowel resection were significantly associated with an increased risk for development of PNALD. PNALD infants received lower protein doses (3.0 vs 3.3 g/kg/day, p = 0.014) while receiving higher GIR (11.4 vs 10.7 mg/kg/min, p = 0.012) compared to non-PNALD infants. Low birth weight, sepsis and bowel resection remain strong indicators of risk for PNALD. No single macronutrient increased our infants’ risk for PNALD. The use of newer ILEs when available should be evaluated for their impact on PNALD development.

我们利用多重事件的反褐积方法分析了1988年12月7日的亚美尼亚斯皮塔克地震的远震P波和S波,以探讨震源过程。长周期远震体波表现出复杂的波形,比通常看到的同等大小的地震显得更复杂。识别出了两组次级事件,其中一组是最初20s期间的走滑事件,另一组是初始破裂之后约30s开始的倾滑事件。所有子事件的张量之和实质上是标量矩为1.47×10^(19)Nm的走滑事件(走向302°、倾角59°、滑动角143°),倾滑事件(走向89°、倾角60°、滑动角88°)的地震矩是5.6×10^(18)Nm,近乎总量的40％,而且与其他具有走滑机制的次事件相比,矩释放速度慢,我们称这种事件为慢速余滑事件。这种慢速余滑事件的机制和由阿拉伯板块与俄罗斯板块之间的大陆碰撞在高加索地区引起的南北压缩为主的现代形变是一致的。结果表明,在一个出现走滑运动和地壳缩短的地方,如南加州大的走滑事件可能伴随着大的逆冲事件,反之亦然。要确定同震形交的图象,在时间、空间和机制上分辨多重事件是十分必要的。

Targets have been developed to measure supersonic radiation transport in aerogel foams usinff absorption spectroscopy. The target consists of an aerogel foam uniformly doped with either titanium or scandium inserted into an undoped aerogel foam package. This creates a localized doped foam region to provide spatial resolution for the measurement. Development and characterization of the foams is a key challenge in addition to machining and assembling the two foams so they mate without gaps. The foam package is inserted into a beryllium sleeve and mounted on a gold hohlranm. The target is mounted to a holder created using additive manufacturing and mounted on a stalk. The manufacturing of the components, along with assembly and metrology of the target are described here.

Design an Automatic Door System using a unique wireless ID by using infrared ray or Bluetooth technology. That consists of a sensing unit, control unit and drive unit to open and close doors at the entrance of a car that has the unique ID. This process is controlled by using Arduino Leonard programmed with IDE free open source software, that receives the signal code from the car which sends the ID through IR LED or Bluetooth by using a mobile application, decode it. And switch ON the driver that controls the DC motor. This system was designed considering some factors such as low cost and low power requirements, availability of components and low distance so there is no interference. The hardware design and software development are described, and all of the tests indicate that all component goes according to the initial design of this research.

Climate change, which is currently characterized by increased atmospheric CO2, rising temperature, and altered pattern of precipitation, is affecting agricultural productivity. Rising temperatures and shifting precipitation patterns will alter the ability to meet crop water requirements, water availability, crop productivity, and costs of water access across the agricultural landscape. Searching for alternative crops with lower water requirements increased yield or organic matter per unit of water are important for agricultural sustainability. Sorghum is one of the world’s important crops;a crop that is adapted to a variety of agronomic and environmental conditions, particularly to areas with low rainfall or limited access of irrigation water. Forage Sorghum is able to produce comparable yield to corn suggesting that there is a potential for Sorghum to replace corn in areas where water supply is limited. But, there is a cost since corn silage, because of its high grain content, which is typically superior in digestible energy content to Sorghum forages. There is also a lack of information on the feeding value of Sorghum silages in high producing dairy cows as well as strategies that may be used for sorghum silage to replace a portion of the corn silage in dairy cattle diets.

Indium tin oxide(ITO) thin film was deposited on glass substrate by means of vacuum evaporation technique and annealed at 200 ℃, 300℃ and 400 ℃ in air for 1 h. The characterization and properties of the deposited film samples were analyzed by X-ray diffraction(XRD), scanning electron microscopy(SEm), and UV-VIS-NIR spectroscopy techniques. From the XRD patterns, it was found that the deposited thin film was of crystalline at an annealing temperature of 400℃. The crystalline phase was indexed as cubic structure with lattice constant and crystallite size of 0.511 nm and 40 nm, respectively. The SEm images showed that the films exhibited uniform surface morphology with well-defined spherical grains. The optical transmittance of ITO thin film annealed at 400 ℃ was improved from 44% to 84% in the wavelength range from 250 nm to 2 100 nm and an optical band gap was measured as 3.86 e V. hall effect measurement was used to measure the resistivity and conductivity of the prepared film.
