Recovery of radar's beat signal based on compressive sampling

Weather radar is a type of radar that used to detect rainfall, the direction of movement and speed, to know the level of rain and cloud composition. One of the problems that occurs in weather radar is the amount of raw data to be acquired in the digital signal processing process is too large, the size until Gigabyte. In order that, we using Compressive Sampling(CS) to reduce the radar's beat signal, as part of weather radar data. CS requires that the signal must be sparse on a certain basis. When using CS the radar's beat signal are compressed by projecting it onto a randomly generated orthogonal matrix and then recovered by ℓ1 norm optimization and Orhogonal Matching Pursuit (OMP) method. From the simulation, all the method of reconstruction can recover the beat signal radar. We also evaluate the relation of compression ratio and reconstruction accuracy. By PSNR measurement, we propose OMP algorithm for the better radar's beat signal reconstruction.
Sensor selection schemes in smart grid

Wireless sensor and actuator networks (WSANs) have been widely implemented in smart grid to monitor and control their environment. We consider the sensor selection schemes for parameter estimation in energy constraint WSANs. To prolong the network lifetime and optimize energy consumption, only sensors experiencing favorable conditions will participate in the estimation process. In this paper, we study two different multiple access schemes between sensors and fusion center (FC): orthogonal and coherent. We compare these two schemes and derive a reasonable lower bound of distortion. Sensor selection scheme under equal power allocation is first discussed. We propose an opportunistic sensor selection scheme by solving an relaxed sensor selection problem. The asymptotic behavior is also investigated. Sensor selection scheme under optimal power allocation is then considered. We address this problem via convex optimization techniques and derive a reminiscent of the “water-filling” solution for this scenario. The validity of the proposed sensor selection schemes is finally demonstrated by numerical simulation results.
Comparison of the BD Viper System With XTR Technology to the Gen-Probe APTIMA COMBO 2 Assay Using the TIGRIS DTS System for the Detection of Chlamydia trachomatis and Neisseria gonorrhoeae in Urine Specimens

Background: Performances of the BD ProbeTec Chlamydia trachomatis (CT)/Neisseria Gonorrhoeae (GC) Qx Amplified DNA Assay reagents on a BD Viper System with XTR Technology and APTIMA COMBO 2 Assay reagents on a TIGRIS DTS platform, for detection of both CT and GC were compared. Methods: A total of 1018 first-void urine specimens were tested for the presence of CT and GC DNA using the 2 assays. Results: CT was detected in 143 specimens (14%). Eight specimens exhibited discordant results, and they were divided equally between the 2 assays. Based on the original results, the overall agreement for CT was 99.2%, with 97.1% and 99.5% in agreement with positive and negative specimens, respectively. Cohen's Kappa was 0.967. GC was detected in 27 specimens (2.6%). Two specimens exhibited discordant results, and they were divided equally between the 2 assays. Based on the original results, the overall agreement was 99.8%, with 96.2% and 99.9% in agreement for positive and negative specimens, respectively. Cohen's Kappa was 0.961. Conclusions: There was a high level of agreement between the systems for both CT and GC detection.
The Deletion of petG in Chlamydomonas reinhardtii Disrupts the Cytochrome bf Complex (*)

The 4-kDa protein encoded by chloroplast petG copurifies with the cytochrome bf complex of spinach and is found in a number of other photosynthetic organisms, including the eukaryotic alga Chlamydomonas reinhardtii. To determine whether petG is involved in the function or assembly of the cytochrome bf complex, the gene was cloned from C. reinhardtii, excised from the DNA fragment, and replaced with a spectinomycin resistance cassette. A petG deletion strain of C. reinhardtii was then obtained by biolistic transformation. The resulting homoplasmic petG deletion strains are unable to grow photosynthetically, and immunoblot analysis shows markedly decreased levels of cytochrome b6, cytochrome f, the Rieske iron-sulfur protein, and subunit IV. To verify that this phenotype was due to the removal of petG, we also constructed a strain with a deletion in the open reading frame (ORF56), which is found 25 base pairs downstream of petG. The ORF56 deletion strain grew photosynthetically and had wild-type levels of the four major cytochrome bf subunits. We conclude that the absence of the PetG protein affects either the assembly or stability of the cytochrome bf complex in C. reinhardtii.
The role of human adenovirus early region 3 proteins (gp19K, 10.4K, 14.5K, and 14.7K) in a murine pneumonia model

Products of human adenovirus (Ad) early region 3 (E3) inhibit both specific (cytotoxic T lymphocytes [CTLs]) and innate (tumor necrosis factor alpha [TNF-alpha]) immune responses in vitro. The E3 gp19K protein prevents CTL recognition of Ad-infected fibroblasts by sequestering major histocompatibility complex class I proteins in the endoplasmic reticulum. E3 proteins 10.4K, 14.5K, and 14.7K function to protect infected cells from TNF-alpha cytolysis. To address the in vivo functions of these proteins, Ad mutants that lack the E3 genes encoding these proteins were inoculated intranasally into C57BL/10SnJ (H-2b) mice. Mutants that lack the gp19K gene failed to alter CTL generation or to affect Ad-induced pulmonary infiltrates. Since gamma interferon (IFN-gamma) is capable of overcoming gp19K suppression of CTL lysis in vitro, mice were depleted of IFN-gamma and inoculated with gp19K mutants. Even when IFN-gamma was depleted, gp19K was incapable of altering pulmonary lesions. These resuls are not in accord with the function of gp19K in vitro and suggest that gp19K does not affect immune recognition in vivo during an acute virus infection, yet they do not exclude the possibility that gp19K blocks immune recognition of Ad during a persistent infection. In contrast, when mice were inoculated with Ad mutants that lack the TNF resistance genes (14.7K and either 10.4K or 14.5K), there was a marked increase in alveolar infiltration and no change in the amounts of perivascular/peribronchiolar infiltration compared with wild-type-Ad-induced pathology. These findings demonstrate the importance of TNF susceptibility and TNF by-products for recruiting inflammatory cells into the lungs during Ad infections.
An elevated urinary albumin excretion predicts de novo development of renal function impairment in the general population.

BACKGROUND We questioned which factors determine the risk for developing renal function impairment. To that purpose, we studied the incidence of newly diagnosed impaired renal function (GFR <60 mL/min/1.73m2) in the PREVEND cohort (N=8592), which is enriched for the presence of albuminuria, and which was first studied in 1997-1998. Of this cohort, 6894 subjects were studied again four years later. METHODS Subjects with known renal disease, GFR <60 mL/min, missing GFR values, or sediment abnormalities at the first screening were excluded from the present analysis (N=872). We examined whether albuminuria is associated with the de novo development of an impaired renal function. GFR was 90.3 (SD 16.3) mL/min/1.73m2 at baseline, and 11.6% of the subjects had an albuminuria of more than 30 mg/day. RESULTS After a follow-up of four years, 253 subjects (4.2%) were found to have a GFR <60 mL/min/1.73m2. The subjects with newly diagnosed impaired GFR were older, had a higher blood pressure, serum cholesterol, plasma glucose, and urinary albumin excretion at the first examination, and had a lower GFR to start with than those with a GFR >60 at the second evaluation. Subjects with de novo impaired GFR had a comparable BMI and smoked less frequently compared with subjects with GFR >60. In multivariate analysis, urinary albumin excretion was independently predictive for the risk of developing an impaired GFR (P=0.001). CONCLUSION Also in the general population, measurement of urinary albumin excretion may prove to be a valuable tool to detect subjects at risk for later development of renal failure, independent of the presence of other cardiovascular risk factors.
Whole Men: The Masculine Tradition in New Zealand Literature

Kai Jensen takes a provocative look at masculinity in New Zealand literature. He argues that New Zealand writing around the Second World War was shaped by excitement about masculinity as a way of challenging society. Inspired partly by Marxism, writers such as A.R. D. Fairburn, Denis Glover, John Mulgan and Frank Sargeson linked national identity to the ordinary working man or soldier, and attempted to merge artistic activity and manliness in a new ideal, the whole man. This masculine excitement forged a literary and intellectual culture which was powerful for thirty years, and which discouraged women writers.Jensen suggests that the aftermath of masculinism still influences the way New Zealand intellectuals see themselves, and that the masculine tradition survives in the writing of Owen Marshall, Sam Hunt, Maurice Shadbolt and even Maurice Gee. At the same time he argues that masculinism underwent a process of change after its high point in the 1940s: Frank Sargeson's closeted homosexuality posed a complex problem for the masculine tradition and its historians, and James K. Baxter's symbolic, Jungian poetry was also hard to reconcile with the idea that men's writing must be based on robust experience. Yet Baxter prepared the masculine tradition for the 1960s and 1970s by renovating the whole man as bohemian lover. "Whole Men" is not just about one literary movement, but about how literary culture works, and how New Zealand intellectuals construct their identities.
Influence of flow rate, temperature and pressure on multiphase flows of supercritical carbon dioxide and water using multivariate partial least square regression

Supercritical carbon dioxide (scCO2) is often used to replace harmful solvents and can dissolve a wide range of organic compounds. With a favorable critical point at 31 °C and 7.4 MPa, reaching above the critical point for scCO2 is fairly accessible. Because of the compressible nature of scCO2 and the large changes of viscosity and density with temperature and pressure, there is a need to determine the behavior of scCO2 in microfluidic systems. Here, the influence of how parameters such as flow rate, temperature, pressure, and flow ratio affects the length of parallel flow of water and scCO2 and the length of the created CO2 segments are investigated and modeled using multivariate data analysis for a 10 mm long double-y channel. The parallel length and segment size were observed in the laminar regime around and above the critical point of CO2. The flow ratio between the two fluids together with the flow rate influenced both the parallel length and the segment sizes, and a higher pressure resulted in shorter parallel lengths. Regarding the segment length of CO2, longer segments were a result of a higher Weber number for H2O together with a higher temperature in the channel.
A Tabu Search-based Approach for Online Motion Planning

In this paper an online motion planner is developed to govern the movements of mobile robots during their explorations. By using the Tabu search meta-heuristic method, a set of tabu (i.e., forbidden) moves are defined in each iteration of the search to confine the robot's navigable locations, and guide it toward the goal. Based on range-sensor readings and the cost function value defined for each ray, the robot is attracted to certain obstacle vertices, and moves along a path consisted of lines connecting the vertices of different obstacles. Hence, the resulting trajectory has a local shortest path quality similar to the visibility graph roadmap. The planner also takes advantage of random moves when trapped in dead-ends. Different experiments have shown the efficiency of this approach.
HER2 testing in gastric and esophageal adenocarcinoma: new diagnostic challenges arising from new therapeutic options

Abstract Adenocarcinomas of the esophagus and stomach constitute a substantial number of cancer cases worldwide. Most patients in the United States are diagnosed at an advanced or metastatic stage and, therefore, the prognoses have been poor. New treatments are needed to augment standard surgical and medical management. Recent studies have shown that a subset of esophageal and gastric adenocarcinomas overexpress the HER2 protein, similar to the overexpression seen in breast cancer. Because trastuzumab, a monoclonal antibody to the HER2 receptor, has been used with success in primary and HER2 positive metastatic breast cancers, the phase III ToGA trial was designed to assess the impact of trastuzumab in patients with HER2 positive gastric cancers. They have reported an increase in overall survival time for patients treated with chemotherapy and trastuzumab compared to those treated with chemotherapy alone. They have reported an increase in overall survival time for patients treated with chemotherapy and trastuzumab compared to those treated with chemotherapy alone. This means that accurate HER2 testing in gastric and esophageal carcinomas is necessary. While the breast cancer scoring system can be used to determine HER2 status in most cases, modifications are necessary to accommodate the heterogeneity and incomplete membrane staining that are observed more frequently in gastric cancers. An understanding of the scoring modifications is required for proper stratification of gastric cancer patients for treatment.
Swelling-induced chloride currents in neuroblastoma cells are calcium dependent

The effects of osmotic stress on chloride (CI-) currents in the human neuroblastoma cell line CHP-100 were evaluated. Following exposure to hypoosmotic solution, an increase in whole-cell CI- current was observed. This current was blocked by the CI- channel blocker 5-nitro-2- (3-phenylpropylamino)-benzoic acid (NPPB). In cells loaded with the CI- permeability marker 125I, exposure to hypoosmotic solution increased 125I efflux by 197 +/- 14% (n = 41, p < 0.05) over controls. This increase was sensitive to NPPB. Hypoosmotic stress also increased cytosolic calcium levels (Ca2+) in fura-2-loaded cells. Pretreatment with EGTA inhibited the increase in cytosolic Ca2+, 125I efflux, and whole-cell CI- current produced by hypoosmotic solution. Antagonists of N-, L-, and T-type Ca2+ channels did not alter stimulation in 125I efflux or cytosolic Ca2+ levels during osmotic stress. However, omega- conotoxin MVIIC, a P-type Ca2+ channel blocker, inhibited hypoosmotically activated whole-cell CI- currents and increases in cytosolic Ca2+. It is concluded that a Ca(2+)-dependent change in CI- permeability is activated in CHP-100 cells in response to osmotic stress.
An Adaptive-Rate Error Correction Scheme for NAND Flash Memory

ECC has been widely used to enhance flash memory endurance and reliability. In this work, we propose an adaptive-rate ECC scheme with BCH codes that is implemented on the flash memory controller. With this scheme, flash memory can trade storage space for higher error correction capability to keep it usable even when there is a high noise level.
A Hybrid LR-EP for Solving New Profit-Based UC Problem under Competitive Environment

With the opening of the power industry to competition, power system structure is changing. According to these changes, power system operation, planning and control need modifications. In the past, utilities had to produce power to satisfy their customers with objective to minimize costs and all demand/reserve were met. However, it is not necessary in a restructured system. Under new structure, generation companies (GenCo) schedule their generators with objective to maximize their own profit without regard for system social benefit. Power and reserve prices become important factors in decision process. This paper proposes a new tool, profit-based unit commitment (UC) considering both power and reserve generatings. The proposed method helps GenCo to make a decision, how much power and reserve should be sold in market and how to schedule generators in order to receive the maximum profit. A hybrid method between Lagrange relaxation (LR) and evolutionary programming (EP) is used for solving this problem. Simulations are carried out to show the performance of the proposed methodology.
Stimulation of the Subthalamic Nucleus in Parkinson’s Disease Does Not Produce Striatal Dopamine Release

OBJECTIVEThe subthalamic nucleus (STN) is a target in the surgical treatment of Parkinson’s disease (PD). The mechanism by which electrical stimulation of the STN ameliorates symptoms of PD remains unknown. One consistent aspect of STN stimulation is the ability to reduce the dosage of dopaminergic medications; sometimes they can be eliminated altogether. Furthermore, nigrostriatal projection axons are apposed to the dorsal surface of the STN and are likely affected by the application of current in this region. We sought to determine whether STN stimulation could release endogenous striatal dopamine. METHODSFive patients with PD, who had previously undergone surgical implantation of bilateral STN stimulators, underwent [11C]raclopride positron emission tomographic scanning. l-dopa was withheld for 12 hours, and both stimulators were turned off 9 hours before scanning. We assayed for striatal dopamine release by measuring radioligand displacement as a consequence of turning on the right STN stimulator after 45 minutes of a 90-minute [11C]raclopride infusion. Patients were evaluated with the motor section of the Unified Parkinson’s Disease Rating Scale before and after the studies. RESULTSComparisons between the right and left striata, before and after right STN stimulation, demonstrated no significant differences in [11C]raclopride binding, despite significant improvements in Unified Parkinson’s Disease Rating Scale motor scores with unilateral stimulation (mean improvement, 26.0 ± 16.4%; P < 0.05). This finding was also noted when the striatum was partitioned into dorsal and ventral caudate and putamen and the four regions were analyzed separately. CONCLUSIONOur results suggest that STN stimulation does not mediate its anti-PD effects via the release of dopamine, as assessed with [11C]raclopride displacement.
Diverse nodule bacteria were associated with Astragalus species in arid region of northwestern China

The legume species of Astragalus as traditional Chinese medicine source and environmental protection plants showed an extensive distribution in the arid region of northwestern China. However, few rhizobia associating with Astragalus have been investigated in this region so far. In this study, 78 endophytic bacteria were isolated from root nodules of 12 Astragalus species and characterized by the PCR‐RFLP of 16S rRNA gene and symbiotic genes together with the phylogenetic analysis. Results showed that the majority (53%) of isolates are non‐nodulating Agrobacterium sp. and the rest are Mesorhizobium genomic species (41%), Ensifer spp. and Rhizobium gallicum (6%), respectively. Mesorhizobium genomic species are broadly distributed in the Astragalus symbioses and most of them share similar symbiotic genes. It seems that horizontal gene transfer occurred frequently among different genomic species independent of their original hosts and sites. Astragalus adsurgens is nodulated by a widely range of rhizobial species in the nodulation test, revealing that it could play an important role in diversification of Astragalus symbionts and that might be a reason for its wide adaptation to diverse environments.
Dietary crocin reverses melanoma metastasis

Crocus sativus and its bioactive constituent crocin are well known for anti-tumor potential in different models. However, the efficacy of crocin on in-vivo melanoma metastasis is not yet reported. In this study, melanoma metastatic model was developed by tail vein injection of B16F-10 cells in to C57BL/6 mice. Metastatic mice treated with two different doses of crocin (250 and 500 µg/kg of bodyweight) for 10 days and parameters such as lung metastasis inhibition, mean survival time, lung hydroxyproline, uronic acid and hexosamine levels were analyzed after 21 days of treatment. Then blood was collected and serum gamma glutamyl transpeptidase ( g-GGT), sialic acid, tumor necrosis factor alpha (TNF-α), interleukin 10 (IL-10), IL-6, IL-2, and TIMP-1 levels were measured. Further, a lung histological examination was done in crocin treated metastatic mice. Subsequently hallmark metastatic parameters such as matrix metalloproteinases (MMPs), extracellular regulated kinase 2 (ERK2), vascular endothelial growth factor (VEGF), and K-ras gene expression were investigated in the lungs of crocin treated metastatic mice. Further, in-vitro adhesion, invasion and migration of B16F-10 cells were examined after 24 hours of crocin (5 and 10 µg/mL) treatment. Administration of crocin to tumor bearing C57BL/6 mice reduced the lung metastasis by 85%. Elevated levels of hydroxyproline, uronic acid, hexosamine, serum sialic acid and g-GGT in metastatic control were found to be significantly reduced in crocin treated mice. Crocin also inhibited expression of MMP-2, MMP-9, ERK-2, K-ras, and VEGF. Crocin reduced the ability of B16F-10 cells invasion (P<0.05), migration (P<0.05) and adhesion by upregulating E-cadherin expression. In conclusion, crocin elicited marked anti-metastatic potential by regulating the metastasis induced biomarkers.
Effect of mechanical properties variation of polysilicon on microcantilever mass sensor sensitivity

Ensuring a high sensitivity for piezoelectric microcantilever sensors constitutes a crucial research subject particularly for the applications such as detection of biochemical entities; virus particles or human biomarkers. However, this sensitivity may change due to the environmental conditions such as temperature, or/and the uncertainty in the material properties, which cause the mechanical properties of the cantilever material changes. The objective of this study is to explore the effect of Young modulus variations of cantilever's structural layer on the sensitivity of the mass sensor. Also, this effect has been investigated for different sensor lengths and resonance modes. As theoretical model, Euler-Bernoulli beam theory has been employed and solved by Galerkian expansion procedure. The results show that error in sensors sensitivity due to variation of Young modulus is almost 3% in this study, and this remains constant regardless of beam length or the resonance mode of the cantilever sensor. Also, the sensitivity of microsensor decreases with increasing the loaded mass. The microsensor sensitivity operating at the second resonant mode has been improved almost five times comparing to the first mode sensitivity regardless of cantilever length.
