Flow-thourgh magnetic separators for weakly-magnetic ores designed for superconducting magnets (1975)

Two flow-through model ore separators have been constructed and tested. Both separators use the magnetic field of a straight wire conductor which deflects magnetic particles in toward the conductor. Nonmagnetic gangue particles in the water slurry are deflected away by gravity in one case and by centrifugal forces in the other case. Tests have been conducted with synthetic ore slurries made up of carefully screened sizes of magnetite and silica. These tests show that separation does take place and that the theoretical separation time expected for ferromagnetic particles in a magnetic field is obtained.
Fast Thermal Calibration of Low-Grade Inertial Sensors and Inertial Measurement Units (2013)

The errors of low-cost inertial sensors, especially Micro-Electro Mechanical Systems (MEMS) ones, are highly dependent on environmental conditions such as the temperature. Thus, there is a need for the development of accurate and reliable thermal compensation models to reduce the impact of such thermal drift of the sensors. Since the conventional thermal calibration methods are typically time-consuming and costly, an efficient thermal calibration method to investigate the thermal drift of a full set of gyroscope and accelerometer errors (i.e., biases, scale factor errors and non-orthogonalities) over the entire temperature range in a few hours is proposed. The proposed method uses the idea of the Ramp method, which removes the time-consuming process of stabilizing the sensor temperature, and addresses its inherent problems with several improvements. We change the temperature linearly for a complete cycle and take a balanced strategy by making comprehensive use of the sensor measurements during both heating and cooling processes. Besides, an efficient 8-step rotate-and-static scheme is designed to further improve the calibration accuracy and efficiency. Real calibration tests showed that the proposed method is suitable for low-grade IMUs and for both lab and factory calibration due to its efficiency and sufficient accuracy.
Mechanically induced osteogenic differentiation – the role of RhoA, ROCKII and cytoskeletal dynamics (2009)

Many biochemical factors regulating progenitor cell differentiation have been examined in detail; however, the role of the local mechanical environment on stem cell fate has only recently been investigated. In this study, we examined whether oscillatory fluid flow, an exogenous mechanical signal within bone, regulates osteogenic, adipogenic or chondrogenic differentiation of C3H10T1/2 murine mesenchymal stem cells by measuring Runx2, PPARgamma and SOX9 gene expression, respectively. Furthermore, we hypothesized that the small GTPase RhoA and isometric tension within the actin cytoskeleton are essential in flow-induced differentiation. We found that oscillatory fluid flow induces the upregulation of Runx2, Sox9 and PPARgamma, indicating that it has the potential to regulate transcription factors involved in multiple unique lineage pathways. Furthermore, we demonstrate that the small GTPase RhoA and its effector protein ROCKII regulate fluid-flow-induced osteogenic differentiation. Additionally, activated RhoA and fluid flow have an additive effect on Runx2 expression. Finally, we show RhoA activation and actin tension are negative regulators of both adipogenic and chondrogenic differentiation. However, an intact, dynamic actin cytoskeleton under tension is necessary for flow-induced gene expression.
Similar Gene Expression Pattern in Senescent and Hyperoxic-Treated Fibroblasts (1998)

Different DNA-damaging treatments produce a senescence-like phenotype. Young human fibroblasts are transferred to a senescence-like state after 4 to 6 weeks of culture under 40% ambient oxygen partial pressure. In order to understand the causes of senescence it would be advantageous to know how well this state equals accelerated senescence. Therefore, we measured the expression of genes with known senescence-specific expression pattern in human fibroblasts, which were irreversibly proliferation-inhibited by chronic hyperoxic treatment. A senescence-specific gene expression pattern was confirmed by semiquantitative RT-PCR for eight out of nine examined genes in BJ foreskin fibroblasts and for four out of four genes in MRC-5 lung fibroblasts. For all these cases, gene expression under hyperoxia was similar to that in senescent cells, suggesting that chronic mild hyperoxia is a valid model for accelerated senescence.

Microcirculatory Hemodynamics During the Acute Phase of Free Vascularized Muscle Allograft Rejection (1998)

This study investigated the microcirculatory pattern during acute rejection of a vascularized free muscle graft. Using a new rat cremaster muscle free flap model, isograft transplantation was done between genetically identical Lewis rats (N = 23) and allograft transplantation across a major histocompatibility barrier (Lewis Brown Norway [RT-11 + n] to Lewis [RT-11] rats; N = 24). At days 1, 3, 5, and 7 posttransplantation, microcirculatory measurements were taken of vessel diameter, red blood cell velocity, endothelial edema index, leukocytic-endothelial interaction (rolling, adhering, and transmigrating leukocytes), and capillary perfusion. In the allografts at 5 days the lumen obstruction was 27% greater (p < 0.05) than onset. The number of perfused capillaries decreased by 36% compared with isografts at day 5 (p < 0.05). The number of adhering leukocytes increased significantly in allografts both at day 1 (71%; p < 0.05) and at day 3 (77%; p < 0.05). At day 3, transmigrating leukocytes rose significantly (p < 0.05). Allograft histology showed myocytic destruction and lymphocytic infiltration at day 5. Our results suggest that the microcirculatory signs of acute muscle allograft rejection occurred 24 hours after transplantation, and preceded histological signs of rejection. The critical time for microvascular survival of muscle allografts was 3 days. This procedure allows us to distinguish events related to transplantation trauma from rejection phenomena.
Detecting the Exchange Phase of Majorana Bound States in a Corbino Geometry Topological Josephson Junction (2015)

A phase from an adiabatic exchange of Majorana bound states (MBS) reveals their exotic anyonic nature. For detecting this exchange phase, we propose an experimental setup consisting of a Corbino geometry Josephson junction on the surface of a topological insulator, in which two MBS at zero energy can be created and rotated. We find that if a metallic tip is weakly coupled to a point on the junction, the time-averaged differential conductance of the tip-Majorana coupling shows peaks at the tip voltages eV=±(α-2πl)ℏ/T_{J}, where α=π/2 is the exchange phase of the two circulating MBS, T_{J} is the half rotation time of MBS, and l an integer. This result constitutes a clear experimental signature of Majorana fermion exchange.
Synthesis and Antitumour Activity of New Derivatives of Flavone‐8‐acetic Acid (FAA). Part 1: 6‐Methyl Derivatives (1996)

A range of 17 derivatives of flavone-8-acetic acid (FAA) with a 6-methyl substituent have been prepared and their anti-tumour activity evaluated in vitro against a panel of human and murine tumour cell lines and in vivo against MAC 15A. While many of the compounds show activity comparable to FAA in vitro, this essentially disappears in vivo, possibly due to degradation before the compounds can reach the tumour site.
Characterization of the <i>Pseudomonas syringae</i> pv. <i>tomato</i> AvrRpt2 protein: demonstration of secretion and processing during bacterial pathogenesis (1999)

Pseudomonas syringae pv. tomato strain DC3000 (Pst DC3000) expressing avrRpt2 is specifically recognized by plant cells expressing RPS2 activity, resulting in localized cell death and plant resistance. Furthermore, transient expression of this bacterial avrRpt2 gene in plant cells results in RPS2-dependent cell death. This indicates that the AvrRpt2 protein is recognized inside RPS2 plant cells and is sufficient for the activation of disease resistance-mediated cell death in planta. We explored the possibility that Pst DC3000 delivers AvrRpt2 protein to plant cells via the hrp (type III) secretion pathway. We now provide direct evidence that mature AvrRpt2 protein is secreted from Pst DC3000 and that secretion is hrp dependent. We also show that AvrRpt2 is N-terminally processed when Arabidopsis thaliana plants are infected with Pst DC3000 expressing avrRpt2. Similar N-terminal processing of AvrRpt2 occurred when avrRpt2 was stably expressed in A. thaliana. No cleavage of AvrRpt2 was detected in bacteria expressing avrRpt2 in culture or in the plant extracellular fluids. The N-terminus of AvrRpt2 was not required for RPS2 recognition in planta. However, this region of AvrRpt2 was essential for Pst DC3000-mediated elicitation of RPS2-dependent cell death in A. thaliana leaves.

Abstract No prior legislation has had as profound an effect on pesticide regulation as has the Food Quality Protection Act of 1996 (FQPA). Created as an amendment to both the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) and the Federal Food, Drug and Cosmetic Act, the implementation of FQPA initiated many improvements in the processes of pesticide regulation. For instance, the FQPA has helped ensure that the public is more protected from potential risks from pesticide exposure than was ensured by previous legislation. Risk‐assessment science and methodologies, in particular, have advanced significantly since the passage of the FQPA. Therefore, the public is assured that the food supply of this nation will be safer as a result of the FQPA and that the nation's infants and children are better protected because of this important legislation.
Link between microbial composition and carbon substrate-uptake preferences in a PHA-storing community (2012)

The microbial community of a fermented molasses-fed sequencing batch reactor (SBR) operated under feast and famine conditions for production of polyhydroxyalkanoates (PHAs) was identified and quantified through a 16 S rRNA gene clone library and fluorescence in situ hybridization (FISH). The microbial enrichment was found to be composed of PHA-storing populations (84% of the microbial community), comprising members of the genera Azoarcus, Thauera and Paracoccus. The dominant PHA-storing populations ensured the high functional stability of the system (characterized by high PHA-storage efficiency, up to 60% PHA content). The fermented molasses contained primarily acetate, propionate, butyrate and valerate. The substrate preferences were determined by microautoradiography-FISH and differences in the substrate-uptake capabilities for the various probe-defined populations were found. The results showed that in the presence of multiple substrates, microbial populations specialized in different substrates were selected, thereby co-existing in the SBR by adapting to different niches. Azoarcus and Thauera, primarily consumed acetate and butyrate, respectively. Paracoccus consumed a broader range of substrates and had a higher cell-specific substrate uptake. The relative species composition and their substrate specialization were reflected in the substrate removal rates of different volatile fatty acids in the SBR reactor.
A hybrid approach to mouth features detection (2002)

This paper presents a novel, robust and flexible method for extracting four mouth features (top of the upper lip, bottom of the lower lip, left and right mouth corners) from facial image sequences. While robustness is referred to subject variability, pose, and image quality, flexibility is begotten by efficient fusion of several information sources and expounding the certainty of the generated results.

Effect of Pesticides on Mortality, Fecundity, and Egg Viability of Geocoris pallens (Hemiptera: Lygaeidae) (1984)

Sublethal doses of the insecticides carbaryl, methidathion, and methomyl, the acaricides dicofol and propargite, the herbicide glyphosate, the defoliant DEF, and the fungicide sulfur were tested as cotton leaf residues on Geocoris pallens Stål. All pesticides except propargite did not significantly increase adult mortality 25 to 192 h after a 24 h acute exposure; neither did they have any detrimental effect on female mortality, fecundity, or egg viability. These results suggest that deleterious long-term effects in predator populations would not occur if insects survived initial treatments. Adult males were more susceptible to methidathion and methomyl, and adult females were more susceptible to propargite. Females exposed to DEF laid more eggs, and females exposed to glyphosate and methomyl laid more viable eggs. Potential beneficial effects of chemicals on predator populations should be considered in the selection of pesticides for pest management programs.
Corn Poppy (Papaver rhoeas) Resistance to ALS-Inhibiting Herbicides and its Impact on Growth Rate (2008)

Fifty corn poppy populations originating from three counties of northern Greece were evaluated for resistance to tribenuron. Twelve of the populations (six sampled from cereal fields and six from margins) were sampled from the county of Thessaloniki, 15 (13 sampled from wheat fields and two from margins) from Kilkis, and 23 (21 sampled from cereal fields and two from margins) from Serres. Fifty, 39, and 95% of the populations sampled from winter wheat fields originating from Thessaloniki, Kilkis, and Serres were resistant (R), respectively. However, all populations sampled from margins of the same areas were susceptible (S). All populations examined were susceptible to 2,4-D and bromoxynil. The level of resistance to tribenuron varied among populations with the herbicide dose required to reduce growth by 50% (GR50) ranging from 41 g ha−1 (R/S, resistance ratio 137) for the least resistant to over 720 g ha−1 (R/S greater than 2,400) for the most resistant populations. Fresh weight accumulation, seed production, and capsule number of eight R populations grown under field conditions were similar to those recorded for eight S populations originating from sites with high proximity of their respective R populations. However, the estimated mean growth rate (MGR) indicated significant differences due to the resistance trait and the population's origin. In particular, the R populations that originating from Thessaloniki and Serres had MGR 1.3 to 4.3 times lower than the respective S populations, whereas the R populations from Kilkis had similar or higher MGR values compared to the respective S populations. The populations with the highest R/S (greater than 2,400) had low MGR values, and the populations with R/S ranging from 1,437 to 2,227 had high MGR values.

Activation of Androgen Receptor, Lipogenesis, and Oxidative Stress Converged by SREBP-1 Is Responsible for Regulating Growth and Progression of Prostate Cancer Cells (2011)

We previously reported that sterol regulatory element-binding protein-1 (SREBP-1) is involved in the transcriptional regulation of androgen receptor (AR) and formation of fatty acid through altered expression of fatty acid synthase (FASN). In this article, we provide a new finding that SREBP-1 induced oxidative stress in prostate cancer cells through increased production of reactive oxygen species (ROS) and expression of NADPH oxidase 5 (Nox5). We have shown that (i) expression of SREBP-1 protein is positively associated with the clinical Gleason grades in human prostate cancer; (ii) genetic overexpression or knockdown of SREBP-1 in prostate cancer cells resulted in corresponding increased or decreased AR, FASN and Nox5 expression, fatty acid and lipid droplet accumulation, and ROS generation; and (iii) SREBP-1 induces and promotes the growth, migration, invasion, and castration-resistant progression of prostate cancer cells in vitro and in vivo. Our data show a novel molecular mechanism by which SREBP-1 promotes prostate cancer growth and progression through alterations in the concerted intracellular metabolic and signaling networks involving AR, lipogenesis, and ROS in prostate cancer cells.
Joint tactical anti-jam communications: a systems approach. (1989)

This study analyzes the conceptual design of a joint tactical anti-jam communication link from a systems point of view. It addresses the requirements and the specifications for a communication system providing an integrated solution for navies operating in closed-sea areas under intense enemy jamming activity. The concept of the proposed system is based on spread spectrum technology and on the Joint Tactical Information Distribution System (JTIDS). Spread spectrum technology has been an area of extensive research for many years. Satisfactory practical solutions have been provided through the implementation of several frequency hopping systems that give partial answer to the anti-jam (AJ) problem. JTIDS is the only hybrid spread spectrum system intended to provide a catholic answer. The AJ performance of the proposed system is examined theoretically under realistic scenarios. System feasibility, from the overall cost standpoint, is evaluated using life cycle costing and sensitivity analysis. The trade-off between the procurement of an original system and a JTIDS-based design is also evaluated, based on the possible research costs. It is assumed that acquisition or procurement of such a system is not limited by any technology transfer barriers.

Effects of methionine on the cytoplasmic distribution of actin and tubulin during neural tube closure in rat embryos (1997)

Research has previously shown that, without methionine supplements, neural tube proteins of rat embryos cultured on bovine sera were hypomethylated and neural tubes failed to close. In the present study, to identify the proteins that became methylated during neurulation, rat embryos were first cultured on methionine-deficient bovine serum for 40 hr, then incubated with puromycin for 1 hr, and, finally, incubated with [methyl-14C]methionine and puromycin for 5 hr. On the basis of molecular weights, isoelectric points, and Western immunoblots, the methyl-14C-labeled proteins were identified as actin, alpha beta-tubulin, and neurofilament L. Indirect immunofluorescence studies indicated that without the addition of methionine to the culture, localization of actin and alpha beta-tubulin in the basal cytoplasm did not occur and these neuroepithelial cells lost their columnar morphology.
