Topological properties of microwave magnetoelectric fields (2014)

Collective excitations of electron spins in a ferromagnetic sample dominated by the magnetic dipole-dipole interaction strongly influence the field structure of microwave radiation. A small quasi-two-dimensional ferrite disk with magnetic-dipolar-mode (MDM) oscillation spectra can behave as a source of specific fields in vacuum, termed magnetoelectric (ME) fields. A coupling between the time-varying electric and magnetic fields in the ME-field structures is different from such a coupling in regular electromagnetic fields. The ME fields are characterized by strong energy confinement at a subwavelength region of microwave radiation, topologically distinctive power-flow vortices, and helicity parameters [E. O. Kamenetskii, R. Joffe, and R. Shavit, Phys. Rev. E 87, 023201 (2013)]. We study topological properties of microwave ME fields by loading a MDM ferrite particle with different dielectric samples. We establish a close connection between the permittivity parameters of dielectric environment and the topology of ME fields. We show that the topology of ME fields is strongly correlated with the Fano-resonance spectra observed at terminals of a microwave structure. We reveal specific thresholds in the Fano-resonance spectra appearing at certain permittivity parameters of dielectric samples. We show that ME fields originated from MDM ferrite disks can be distinguished by topological portraits of the helicity parameters and can have a torsion degree of freedom. Importantly, the ME-field phenomena can be viewed as implementations of space-time coordinate transformations on waves.
Arabidopsis thaliana eIF4E1 and eIF(iso)4E Participate in Cold Response and Promote Translation of Some Stress-Related mRNAs (2021)

Plant defense and adaptation to adverse environmental conditions rely on gene expression control, such as mRNA transcription, processing, stability, and translation. Sudden temperature changes are common in the era of global warming; thus, understanding plant acclimation responses at the molecular level becomes imperative. mRNA translation initiation regulation has a pivotal role in achieving the synthesis of the appropriate battery of proteins needed to cope with temperature stress. In this study, we analyzed the role of translation initiation factors belonging to the eIF4E family in Arabidopsis acclimation to cold temperatures and freezing tolerance. Using knockout (KO) and overexpressing mutants of <i>AteIF4E1</i> or <i>AteIF(iso)4E</i>, we found that AteIF4E1 but not AteIF(iso)4E overexpressing lines displayed enhanced tolerance to freezing without previous acclimation at 4°C. However, KO mutant lines, <i>eif(iso)4e-1</i> and <i>eif4e1-KO</i>, were more sensitive to the stress. Cold acclimation in wild-type plants was accompanied by increased levels of <i>eIF4E1</i> and <i>eIF(iso)4E</i> transcript levels, polysomes (P) enrichment, and shifts of these factors from translationally non-active to active fractions. Transcripts, previously found as candidates for eIF(iso)4E or eIF4E1 selective translation, changed their distribution in both P and total RNA in the presence of cold. Some of these transcripts changed their polysomal distribution in the mutant and one eIF4E1 overexpressing line. According to this, we propose a role of eIF4E1 and eIF(iso)4E in cold acclimation and freezing tolerance by regulating the expression of stress-related genes.
Attenuation of maternal psychophysiological stress responses and the maternal cortisol awakening response over the course of human pregnancy (2010)

The effects of maternal stress during pregnancy may depend, in part, on the timing in gestation of the occurrence of stress. The aim of the present study was to examine the effect of stage of gestation on maternal psychophysiological responses to stress using a standardized laboratory paradigm and on the cortisol response to awakening (CAR). A longitudinal design was employed to quantify maternal psychophysiological stress reactivity [changes in heart rate (HR), blood pressure, salivary cortisol, and psychological distress in response to the trier social stress test (TSST)] and the CAR at approximately 17 and 31 weeks gestation in a sample of 148 women. To account for the possible effects of habituation when being exposed to the same stress protocol twice, a non-pregnant comparison group (CG, N = 36) also underwent these assessments at two time points, with a comparable time interval between the assessments. In both groups, the TSST elicited significant changes in maternal HR, mean arterial pressure, and psychological distress levels but not a significant increase in cortisol levels. Among the pregnant women (pregnant group(PG)), the stressor-induced increases in HR, blood pressure, and psychological distress were significantly lower at the second (31 weeks gestation) compared to the first (17 weeks gestation) assessment of pregnancy (all p < 0.01). The maternal CAR was also significantly attenuated in later compared to earlier gestation (p = 0.003). In the CG, there were no significant differences in psychophysiological stress responses and in the CAR across the two assessments. Among pregnant women there is a progressive attenuation of psychophysiological stress responses with advancing gestation. This attenuation is unlikely to be attributable to habituation. Individual differences in the degree of attenuation of stress responses over gestation may represent a novel marker of stress susceptibility in human pregnancy.
3D image reconstruction and application for micro-manipulation systems (2005)

In this paper, a microscopic 3D image is reconstructed for a micro-manipulation system. The 3D image reconstruction is based on a binocular stereo vision system. We propose a new method called "support value" to solve correspondence problems. Geometric constraints are added to reduce the ambiguities in stereo matching. Left/right consistency check is used to increase the confidence for matching results. Post-processing helps remove the outliers and make original dense disparity map smooth and reliable. The three-dimensional characteristics can be reconstructed by perspective projection. Finally, the 3D image reconstruction algorithm is successfully applied to a micro manipulation system for cell image reconstruction by a simpler and more friendly way.
Reduced mortality in cystic fibrosis patients treated with tobramycin inhalation solution (2011)

Abstract Background Though tobramycin inhalation solution has been used for over a decade to improve lung function and reduce exacerbations in patients with cystic fibrosis (CF), its effects on mortality have not been well‐described. This study aimed to assess the association between use of tobramycin inhaled solution and mortality in patients with CF and chronic Pseudomonas aeruginosa (PA) infection. Methods Longitudinal logistic regression was used to assess the association between current‐year reported use of tobramycin inhalation solution and subsequent‐year mortality of patients meeting recommended criteria for tobramycin inhalation solution use in the United States Cystic Fibrosis Foundation's Patient Registry (1996–2008). Results Among 12,740 patients meeting inclusion criteria, 2,538 deaths were observed during a median follow‐up of 6 years. After regression adjustment, use of tobramycin inhaled solution was associated with a 21% reduction in the odds of subsequent year mortality (odds ratio (95% CI): 0.79 (0.72–0.88), P < 0.001). In our model, use of dornase alfa was also associated with a 15% reduction in the odds of subsequent year mortality (odds ratio (95% CI): 0.85 (0.76–0.95), P = 0.005). Underweight for age, CF‐related diabetes, female gender, worse lung function and cultures positive for Pseudomonas aeruginosa or Burkholderia cepacia complex, among multiple other patient characteristics, were associated with significantly increased mortality. Adjusted mortality rates for patients reporting tobramycin inhalation solution use in all versus none of the follow‐up years were 1.3% versus 2.1% at 2 years, 5.2% versus 8.0% at 5 years, and 9.9% versus 15.0% at 10 years. Conclusion After adjustment for multiple patient characteristics and known risk factors, use of tobramycin inhalation solution was associated with significantly reduced mortality among patients with CF.

PREPARATION OF ULTRAFINE SI POWDERS FROM SIH4 BY LASER-INDUCED GAS-PHASE REACTION (1995)

High quality ultrafine Si powders have been synthesized from SiH4 by laser induced gas phase reaction. The powders produced under different synthesis conditions have mean particle size of 10-120 nm in diam. with narrow particle size distribution, and free of hard agglomerates. The powders are polycrystalline with the ratio of mean grain to particle diameter being between 0.3-0.7. The size of the powder increases with increasing laser power and reaction pressure, but decreases with increasing silane gas flow rate and the addition of Ar diluent. Grain sizes drop distinctly with the rise of the addition of Ar gas and laser power, but change little with the gas flow rate and reaction temperature. The formation of Si particles under different synthesis conditions is discussed.

Application of a species-selective Penning gauge to the measurement of neon and hydrogen-isotope partial pressures in the plasma boundary (1997)

A species-selective Penning gauge, previously applied to He partial pressures, is now applied to the detection of small concentrations of Ne in a D2 gas. This is important for the study of Ne in the boundary region of magnetic fusion devices, where this impurity is deliberately injected to enhance the radiated power in that region. The application of the technique to the detection of the partial pressure of a minority hydrogen isotope is also examined. In this latter application, the detection system and the data analysis are more complex, because of the proximity of the spectral lines of the isotopes. In both applications, it is found that use of a proper detection scheme permits reliable measurements of concentrations as low as 0.5% of the minority neutral species, without requiring changes to the standard commercial Penning gauge setup.

A nonpathogenic strain of Citrobacter sedlakii which expresses the Escherichia coli O157 antigen is described. The discovery of this strain emphasizes the necessity of additional biochemical and/or toxigenicity testing when isolates react with E. coli O157 latex reagents.
Several programming models with unascertained parameters and their applications (1999)

Several programming models are introduced with the consideration of available unascertained information. In this case, the so-called unascertained information is some numerical values whose ranges are known but their exact values are not. These models resolve several vital weaknesses of the traditional programming methods to a certain degree. Our study includes considerations of linear and non-linear programming models with grey parameters, grey 0–1 programming, and satisfactory and quasi-optimal solutions of grey linear programmings. Finally, some practical applications are given in order to test the applicability of our theory. Copyright © 1999 John Wiley & Sons, Ltd.
Experiments to achieve accurate vision guided robot movements (2002)

Highly accurate sensor based robot movements are demanded in many light assembly applications. In our study the goal is to implement a vision sensor in the gripper frame of a robotic manipulator to investigate how to achieve high accurate but at the same time flexible movements. Our sensor comprises two cameras and a suitable lighting. The 3D coordinates of the objects close to the grasping point are extracted based on the normal stereo disparity calculations. The recent results of our experiments shows that we are able to achieve the accuracy of about 20 micrometers in the area of 90/spl times/70 mm/sup 2/ and that our control method is capable of driving the robotic manipulator according to this accuracy. In this paper we describe our control method and the performance of the sensor as well as the preliminary results of our studies.

Optically induced light scattering and beam distortion in iron-doped lithium niobate (1983)

In using lithium niobate crystals for optical applications such as the storing of phase holograms, a potentially serious problem is the progressive development of optically-induced beam distortion and diffuse scattering. Experimental observations are reported on these effects using a single laser beam. It was found that the beam is eventually reduced to a small fraction of its initial magnitude. A ray tracing calculation confirms that the observed distortion of the high intensity part of the beam is consistent with the lens action of the observed pattern of induced refractive index change due to a single beam. This distortion effect is distinguished from the scattering process which produces lobes along the c-axis and is strongly angular sensitive. It is clear that the observed scattering is due to parasitic gratings. These are produced by interference between undeflected light and light which has been scattered by some triggering process. The model we propose for the scattering process is as follows. Due to bulk and surface inhomogeneities, a speckle pattern develops within the crystal. The high intensity parts of the speckle pattern produce sharp index variations which act as lenses to decollimate the light and cause it to interfere with other parts of the beam. As a result, parasitic gratings will be produced which cause the observed scattering pattern. Such a model explains the observed experimental results as well as other results reported in the literature.
Trends in Data Centre Energy Consumption under the European Code of Conduct for Data Centre Energy Efficiency (2017)

Climate change is recognised as one of the key challenges humankind is facing. The Information and Communication Technology (ICT) sector including data centres generates up to 2% of the global CO2 emissions, a number on par to the aviation sector contribution, and data centres are estimated to have the fastest growing carbon footprint from across the whole ICT sector, mainly due to technological advances such as the cloud computing and the rapid growth of the use of Internet services. There are no recent estimations of the total energy consumption of the European data centre and of their energy efficiency. The aim of this paper is to evaluate, analyse and present the current trends in energy consumption and efficiency in data centres in the European Union using the data submitted by companies participating in the European Code of Conduct for Data Centre Energy Efficiency programme, a voluntary initiative created in 2008 in response to the increasing energy consumption in data centres and the need to reduce the related environmental, economic and energy supply security impacts. The analysis shows that the average Power Usage Effectiveness (PUE) of the facilities participating in the programme is declining year after year. This confirms that voluntary approaches could be effective in addressing climate and energy issue.
Fiber-optic aerial cables (1981)

The benefits of aerial cables–modest installation cost, use of existing lines–are enhanced by the low weight and small diameter of fiber-optic cables with the optional surplus of a fully dielectric design. However, while conventional cable elements may tolerate strains of 1 %, optical fibers cannot. The present state of investigation does not allow long length fiber strain of more than 0.1 % in the long term. Former optimistic estimates of ≥0.5% generally have been reduced to ≤0.2%. Clear results in moist environments need giant efforts not yet made. As cable strains can reach or exceed 0.5%, practical cable designs are needed for not loading fibers in loaded cables. Alternative proposals of moisture impermeable jackets to make high fiber strains feasible are not realistic. Excluding weak fiber points by the proof test does not help unless fiber strain remains far below test strain, and the subsequent growth of remaining defects is slow enough to be safe. As fibers in stranded cables are never straight, they react to longitudinal forces by Irregular bends creating undesired changes in optical behavior.
Assessment of the hemostatic effectiveness of human platelets treated with aminomethyltrimethyl psoralen and UV A light using a rabbit ear bleeding time technique (1993)

The photochemical aminomethyltrimethyl psoralen (AMT), in conjunction with UV A light (UVA), has been shown to inactivate human immunodeficiency virus-1 and model viruses in platelet suspensions under conditions that have only a minimal effect on in vitro platelet properties. A rabbit ear bleeding time technique was used to assess the hemostatic effectiveness of human platelet suspensions treated with AMT/UVA. New Zealand White rabbits were made thrombocytopenic by a combination of irradiation and heterologous antirabbit platelet antiserum. Reticuloendothelial function in these rabbits was suppressed by the intravenous administration of ethyl palmitate. The hemostatic function of 1- and 5-day-old human platelet suspensions (14.5% plasma) that had been treated on day 1 with 40 micrograms/mL AMT and 24 kJ/m2 UVA (1 x UVA) was evaluated by measuring microvascular bleeding times after a standard incision. Comparable bleeding times were observed after infusion with both control and AMT/UVA-treated platelets stored for either 1 or 5 days. With the transfusion of AMT/1 x UVA-treated platelets stored for 5 days, the mean (+/- SD) bleeding time was 156.3 +/- 39.2 seconds (n = 10). With untreated platelets (no AMT/no UVA), stored for 5 days, the mean bleeding time was 189.2 +/- 36.4 seconds (n = 10). Neither AMT nor 1 x UVA treatment alone influenced the observed bleeding times. In contrast, the hemostatic effectiveness of human platelet suspensions was diminished if they were exposed to three times the standard UVA dose (72 kJ/m2) on day 1 and stored for 4 more days, regardless of whether AMT was present, with the mean bleeding time increasing to 442.2 +/- 122.6 seconds (n = 15, AMT present) or 396.0 +/- 45.9 seconds (n = 10, AMT absent). These results are consistent with data obtained from in vitro studies and indicate that virucidal AMT/1 x UVA treatment does not influence platelet hemostatic function. However, the final conditions to achieve these results must be carefully controlled.
Las traiciones de los cuerpos en tres cuentos de Enrique Serna (2006)

Uno de los practicantes de la prosa mexicana mas importantes que forma parte integral de la generacion actual es, sin duda , Enrique Serna. Desde que se estreno en 1989 con la novela Uno sonaba que era rey , obra que trata en manera satirica las varias clases sociales mexicanas, la critica coincide en que Serna e s un observador astuto de la condicion humana. Esto no quiere decir que Serna no tenga un sentido de humor; comenta Raquel Mosqueda que el forma parte de una larga tradicion de escritores mexicanos que se han empenado muy bien la tarea de con tar,  imaginar o fabular desde y a traves del humor, la parodia y la ironia (117). Lauro Zavala tambien reconoce este elemento humoristico de Serna al incluir sus cuentos en la categoria del cuento posmoderno ludico, aunque agrega que los cuentos de este autor tienen un caracter moral (65).
Fixing positive change (2015)

Purpose – This article aims to outline how tangible objects can encourage more efficient working practices and how they can be powerful tools for leading change within an organisation. It looks specifically at how Toyota, Haier and IDEO have very powerful symbols and the type of behaviour this wish to encourage with the company. Design/methodology/approach – This paper discusses the use of objects as powerful symbols and relates this to three specific companies. Findings – It might seem strange to denote core values through such things as a long piece of rope running through a factory, a sledgehammer attached to a company wall and a small bell that is occasionally rung in meetings. Chosen carefully, however, and with real meaning behind them, those objects can be very powerful symbols that have a lasting impact on corporate culture and can encourage positive change within the organisation. Originality/value – This article outlines how tangible objects can encourage more efficient working practices and how they can be powerful tools for leading change within an organisation.
Mach-Zehnder interferometer tuning with Ta_2O_5 film loading (1983)

Unwanted path length variations cause integrated optical Mach-Zehnder modulators to have random intrinsic phase and directional couplers to have uncertain coupling lengths. The feasibility of tuning these devices by modifying the propagation constant with Ta2O5 loading of Ti:LiNbO3 waveguides was studied. The intrinsic phase of a Mach-Zehnder modulator was adjusted by this method.
