Association of normal systolic blood pressure in the emergency department with higher in‐hospital mortality among hypertensive patients (2019)

Blood pressure is commonly elevated at the hospital emergency department (ED), especially among hypertensive patients. The aim of the study was to determine the association between ED systolic blood pressure (SBP) and in-hospital mortality among hypertensive patients. The authors retrospectively retrieved records of hypertensive patients who were hospitalized during a seven-year period. The authors examined the association between SBP and in-hospital mortality rate, adjusted for demographics, heart rate, comorbidities, laboratory results, and hospital ward. Overall, 96 423 patients were included. Compared to patients with SBP 110-139 mm Hg, the adjusted odds ratios were 4.1 (95% CI, 3.7-4.6) with SBP <90, 1.6 (95% CI, 1.4-1.7) with SBP 90-109, 0.7 (95% CI, 0.6-0.7) with SBP 140-159, 0.7 (95% CI, 0.6-0.7) with SBP 160-179, 0.7 (95% CI, 0.6-0.8) with SBP 180-199, 0.9 (95% CI, 0.7-1.1) with SBP 200-219, and 1.1 (95% CI, 0.7-1.7) with SBP ≥220 mm Hg. Thus, SBP levels of 110-139 mm Hg were associated with higher in-hospital mortality in comparison with elevated SBP up to 200 mm Hg.
V. Experiments on the action of light on Bacillus anthracis (1893)

Abstract It is abundantly evinced by experiments that direct insolation in some way leads to the destruction of spores of Bacillus anthracis, and in so far the results merely confirm what had already been dis­covered by Downes and Blunt in 1877 and 1878. From the fact that an apparent retardation of the development of the colonies on plates exposed to light was observed several times under circumstances which suggested a direct inhibitory action of even ordinary day-light, the author went further into this particular question with results as startling as they are important, for if the explanation given of the phenomena observed in the following experiments turns out to be the correct one, we stand face to face with the fact that by far the most potent factor in the purification of the air and rivers of bacteria is the sun-light.
Flüssigkeitsmanagement - Pathophysiologische Grundlagen sowie intra- und perioperatives Monitoring (2006)

Die pathophysiologischen Effekte der Flüssigkeits-und Volumentherapie beruhen auf den pharmakologischen Eigenschaften und der Menge der perioperativ infundierten Flüssigkeiten. Durch Veränderung der Gefäßpermeabiltät im Stressstoffwechsel führen Fehldosierungen, als auch Produktnebenwirkungen, zu einer Einschränkung der Organfunktion mit konsekutiv beeinträchtigtem postoperativen Outcome des Patienten. Durch ein situativ angepasstes Monitoring kann hier Kenntnis über den Volumenstatus des Patienten gewonnen werden, um Therapiefehler zu vermeiden.
A Stakeholder's Communication Approach for Balancing Hospital Information Systems Investment Priorities (1995)

The Stakeholders Communication Approach is aimed at supporting the decision process in the choice of information systems (IS) applications at the start of a hospital IS planning cycle. It promotes discussion among senior management, key stakeholders, IS Department management, end users and the Accounting Department using specific tools and a negotiation process. The IS applications portfolio profile allows visualizing the hospital's strategic position and directions for development of IS. End users' responses to a questionnaire give a measure of "user functional value added" (UFVA) to inform management about the effectiveness and usefulness of the systems implemented. Stakeholders' evaluation of recently completed IS applications uses UFVA and cost, both separately and combined, along with assessment of strategic changes, to edify the priority-balancing process for deciding on investments in further IS applications.
Light propagation (2008)

The history of optics is filled with examples of unique uses and situations that are beyond the scope of this book which is intended for the student on a first year optics course. However, a brief review is necessary to show how man has been trying to understand and describe light over the last 2500 years.
Partially unzipped carbon nanotubes as a superior catalyst support for PEM fuel cells (2011)

Partially unzipped carbon nanotubes prepared by strong oxidation and thermal expansion of carbon nanotubes were explored as an advanced catalyst support for PEM fuel cells. The unique hybrid structure of 1D nanotube and 2D double-side graphene resulted in an outstanding electrocatalytic performance.
Angiotensin II and Its Receptor Subtypes in the Human Retina (2007)

In the human retina, identification of Ang II and its bioactive metabolite Ang-(1-7) in Müller cells suggests that these glial cells are able to produce and process Ang II. Ang receptors were localized in the blood vessels and neural cells. Local Ang II signaling may thus allow for autoregulation of neurovascular activity. Such an autonomous system could modulate the onset and severity of retinovascular disease.
miR‐34b Modulates Skeletal Muscle Cell Proliferation and Differentiation (2017)

Myogenesis involves myoblast proliferation and differentiation to myocytes, followed by fusion and hypertrophy to form myotubes during muscle development. Increasing evidence showed that microRNAs (miRNAs) play important roles in the regulation of myogenesis. We have previously revealed that miR-34b is steadily increased during this process. This miRNA regulates differentiation in various cell types, though its function in myogenesis remains to be elucidated. In this study, we show that miR-34b represses muscle cell proliferation and promotes myotube formation. Our quantitative iTRAQ-based proteomic analysis reveals 97 proteins are regulated by miR-34b in mouse myoblast C2C12. We identified that miR-34b targets 14-3-3 protein gamma, adenosylhomocysteinase and nucleolin by binding to their 3'UTR. Further analysis of these proteins expression patterns show that nucleolin is a cognate target of miR-34b during myogenic differentiation. Here, we proved that a moderate reduction of nucleolin in cells enhanced the myotube formation. However, nucleolin is required for myogenesis, as cells with low levels of nucleolin reduced cell proliferation rate and are unable to differentiate. Our data demonstrated that nucleolin regulates myogenesis in a protein-abundance-dependent manner. J. Cell. Biochem. 118: 4285-4295, 2017. © 2017 Wiley Periodicals, Inc.
A study on fractional COVID‐19 disease model by using Hermite wavelets (2021)

The preeminent target of present study is to reveal the speed characteristic of ongoing outbreak COVID-19 due to novel coronavirus. On January 2020, the novel coronavirus infection (COVID-19) detected in India, and the total statistic of cases continuously increased to 7 128 268 cases including 109 285 deceases to October 2020, where 860 601 cases are active in India. In this study, we use the Hermite wavelets basis in order to solve the COVID-19 model with time- arbitrary Caputo derivative. The discussed framework is based upon Hermite wavelets. The operational matrix incorporated with the collocation scheme is used in order to transform arbitrary-order problem into algebraic equations. The corrector scheme is also used for solving the COVID-19 model for distinct value of arbitrary order. Also, authors have investigated the various behaviors of the arbitrary-order COVID-19 system and procured developments are matched with exiting developments by various techniques. The various illustrations of susceptible, exposed, infected, and recovered individuals are given for its behaviors at the various value of fractional order. In addition, the proposed model has been also supported by some numerical simulations and wavelet-based results.
The structure of light in photonic crystal waveguides (2009)

With a phase-sensitive near-field microscope we measure the propagating of light through a 2D photonic crystal waveguide. We study how the different Bloch harmonics of the propagating light evanescently decay into the air above the waveguide. Furthermore, exploiting the phase sensitivity of our microscope, we are able to reconstruct the electric vector field distribution with subwavelength resolution. In the complex field we observe both time-dependent and time-independent polarization singularities and determine the topology of the surrounding electric field.

Selecting Suitable Battery Technologies for Untethered Robot (2023)

Untethered robots carry their own power supply in the form of a battery pack, which has a crucial impact on the robot’s performance. Although battery technologies are richly studied and optimized for applications such as electric vehicles, computers and smartphones, they are often a mere afterthought in the design process of a robot system. This tutorial paper proposes criteria to evaluate the suitability of different battery technologies for robotic applications. Taking into consideration the requirements of different applications, the capabilities of relevant battery technologies are evaluated and compared. The tutorial also discusses current limitations and new technological developments, pointing out opportunities for interdisciplinary research between the battery technology and robotics communities.
SIROM3 -- A Scalable Intelligent Roaming Multi-modal Multi-sensor Framework (2014)

Understanding the future transportation infrastructure performance demands a smart Cyber-Physical Systems (CPS) approach integrating heterogeneous sensors, versatile computing systems, and mobile agents. However, due to sensor versatility and computing intricacy, designing such systems faces challenges of immense complexity in mobile sensor fusion, big data handling, system scalability, and integration.

Automatic Parameter Estimation for the Discrete Algebraic Reconstruction Technique (DART) (2012)

Computed tomography (CT) is a technique for noninvasive imaging of physical objects. In the discrete algebraic reconstruction technique (DART), prior knowledge about the material's densities is exploited to obtain high quality reconstructed images from a limited number of its projections. In practice, this prior knowledge is typically not readily available. Here, a fully automatic method, called projection distance minimization DART (PDM-DART), is proposed in which the optimal grey level parameters are adaptively estimated during the reconstruction process. To apply PDM-DART, only the number of different grey levels should be known in advance. Simulation as well as real μCT experiments show that PDM-DART is capable of computing reconstructed images of which the quality is similar to reconstructions computed by conventional DART based on exact prior knowledge, thereby eliminating the need for tedious and error-prone user interaction.
The Effect of Shiga Toxin on Weibel-Palade Bodies in Primary Human Endothelial Cells (2014)

Stx1 can contribute, via an effect on WPbs, to the exocytosis of WPbs in flow conditions in HUVECs and probably in GMVECs. This results in the release of VWF, suggesting an initiating role of the coagulation system in the pathogenesis.
Generation of a stable packaging cell line producing high-titer PPT-deleted integration-deficient lentiviral vectors (2020)

The risk of insertional mutagenesis inherent to all integrating exogenous expression cassettes was the impetus for the development of various integration-defective lentiviral vector (IDLV) systems. These systems were successfully employed in a plethora of preclinical applications, underscoring their clinical potential. However, current production of IDLVs by transient plasmid transfection is not optimal for large-scale production of clinical grade vectors. Here, we describe the development of the first tetracycline-inducible stable IDLV packaging cell line comprising the D64E integrase mutant and the VSV-G envelope protein. A conditional self-inactivating (cSIN) vector and a novel polypurine tract (PPT)-deleted vector were incorporated into the newly developed stable packaging cell line by transduction and stable transfection, respectively. High-titer (~107 infectious units (IU)/ml) cSIN vectors were routinely generated. Furthermore, screening of single-cell clones stably transfected with PPT-deleted vector DNA resulted in the identification of highly efficient producer cell lines generating IDLV titers higher than 108 IU/mL, which upon concentration increased to 1010 IU/ml. IDLVs generated by stable producer lines efficiently transduce CNS tissues of rodents. Overall, the availability of high-titer IDLV lentivirus packaging cell line described here will significantly facilitate IDLV-based basic science research, as well as preclinical and clinical applications.
Hot-Pressing Sintering and Analytical Characterization of Coated Particle-Dispersed Fuel Pellets (2023)

Abstract Coated particle-dispersed fuel pellets have the characteristics of high thermal conductivity and multilayer protection against fission products, which are an important component of ATF fuel. In this paper, by carrying out research on the dressing process of TRISO particles, it is realized that SiC powder completely encapsulates TRISO particles. The hot-pressing sintering method was used to study the influence of different sintering aids, different hot-pressing sintering holding time, different hot-pressing sintering temperature, different hot-pressing sintering pressure and different powder particle size on the density of pellets. The power with a particle size of 10nm is sintered at 3% sintering aid, 1690 ℃, 1.5h holding time, 80 MPa vacuum hot pressing, and a full ceramic micro-encapsulated fuel core with a relative density of 95% or more is prepared, and the internal particle structure is complete.
Emergence of distinct fatigue limit: impact of excess solute magnesium in 6061-T6 alloy (2018)

The fatigue properties of 6061-T6 aluminum (Al) alloy containing additional solute magnesium (Mg) is studied. As previously reported, this special alloy exhibits eminent strain-aging characteristics which is absent in a normal 6061-T6 alloy with a stoichiometric Mg2Si composition. In this study, particular attention is paid to the environmental effect on the fatigue properties of this new alloy. The S-N curves of the alloys are compared in different environments (ambient air, dry air, dry nitrogen). A clear knee-point (fatigue limit), which is atypical to the normal 6061-T6 alloy, appears for the new alloy irrespective of the environment. The fatigue limit is shown to be controlled by the threshold against small crack propagation in all environments. On the other hand, the coaxing effect, the manifestation of a time-dependent strengthening mechanism at the non-propagating crack tip, is clearly observed in the ambient air.
Mating-system evolution in Euplotes, from the Mendelian to a molecular approach. (2013)

Euplotes evolved multiple mating systems which have for long been assumed to be determined by "open" series&#13;\nof alleles at a single mat locus. Families of mating type-specific pheromones and of their mat coding genes have&#13;\nbeen extensively characterized from Euplotes species lying in different positions of Euplotes phylogenetic tree,&#13;\nand this characterization permitted the study of Euplotes mating systems to evolve from a Mendelian to a&#13;\nmolecular approach. While early branching species (e.g. E. raikovi) show a mating-type determination at a single&#13;\nmat locus in accord with Mendelian genetics, late branching species (e.g. E. crassus) revealed, in disagreement&#13;\nwith Mendelian genetics, a mating-type determination at two distinct mat loci implying an event of mat-gene&#13;\nlocus duplication. One locus (orthologous) appears to be multi-allelic and deputed to synthesize pheromones&#13;\ndistinctive of different mating types, and the second one (paralogous) deputed to synthesize pheromones that&#13;\nare structurally identical among different mating types.
Microstructure of Plasma-Sprayed Cast Iron Splats with Different Particle Sizes (2003)

The superior wear-resistant property of cast irons is closely linked with their microstructure, in which graphite formation in plasma-sprayed cast iron coatings causes distinct characteristics owing to its self-lubricating property. Since the solidification rate generally affects graphite formation, the optimum in spray parameters such as substrate temperature, ambient pressure, particle size and spray distance is required to slow down the solidification rate, as well as to improve the adhesive strength of splats. In this study, cast iron splats were induced on an aluminum alloy substrate by plasma spraying using alloyed cast iron powder high in silicon and aluminum in a low pressure argon atmosphere. Then, the effects of particle size on the microstructure and adhesive strength of splats were investigated by introducing the correlation between the solidification rate and the microstructure. Spraying with large particles leads to an increase in the number fraction of disk splats and a slight decrease in their adhesive strength. Cross-sectional observations reveal fine graphite growing in splats nearly perpendicular to the substrate surface.
An immersive visualization system for virtual 3D city models (2012)

Virtual 3D city models are essential visualization tools for effective communication of complex urban spatial information. Immersive visualization of virtual 3D city models offers an intuitive access to and an effective way of realization of urban spatial information, enabling new collaborative applications and decision-support systems. This paper discusses techniques for and usage of fully immersive environments for visualizing virtual 3D city models by advanced 3D rendering techniques. Fully immersive environments imply a number of specific requirements for both hardware and software, which are discussed in detail. Further, we identify and outline conceptual and technical challenges as well as possible solution approaches by visualization system prototypes for large-scale, fully immersive environments. We evaluate the presented concepts using two application examples and discuss the results.

Study of the Self-Assembling of n-Octylphosphonic Acid Layers on Aluminum Oxide (2008)

The deposition of n-octylphosphonic acid on aluminum oxide was studied. The substrate was pretreated in order to achieve a root-mean-square roughness of <1 nm, a hydroxyl fraction of 30%, and a thickness of approximately 170 nm. It was proven using X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) that, rather than a monolayer, an organic multilayer was formed. The growth mechanism was identified as a Stranski-Krastanov one. It was also shown that the use of AFM, probing the surface topography, is essential for a reliable quantification and interpretation of data obtained with XPS.
Cavity quantum electro-optics (2010)

The quantum dynamics of the coupling between a cavity optical field and a resonator microwave field via the electro-optic effect is studied. This coupling has the same form as the optomechanical coupling via radiation pressure, so all previously considered optomechanical effects can in principle be observed in electro-optic systems as well. In particular, I point out the possibilities of laser cooling of the microwave mode, entanglement between the optical mode and the microwave mode via electro-optic parametric amplification, and back-action-evading optical measurements of a microwave quadrature.
Phase analysis of AlFe 2 B 2 by synchrotron X-ray diffraction, magnetic and Mössbauer studies (2017)

The structural and magnetic properties of essentially phase pure AlFe2B2 prepared by arc melting were compared with a sample containing impurities. Analysis was carried out by means of synchrotron X-ray diffraction, magnetic measurements and Mössbauer spectroscopy. The analysis of synchrotron X-ray diffraction data confirmed the orthorhombic structure of space group Cmmm for AlFe2B2 with Al13Fe4 as main impurity phase. The magnetic measurements revealed an unsaturated ferromagnetic state in AlFe2B2 with a transition temperature (Tc) of 286 K. Isothermal magnetization measurment at 5 K gave a saturation magnetization of 0.7 μB per Fe atom while Arrott plots establish the second order nature of ferromagnetic transition. The thermal evolution of Mössbauer spectra confirmed the ferromagnetic nature of this material revealing an hyperfine field of 73 kOe and an isomer shift of 0.46 mm/s at 100 K. The Mössbauer spectra of a phase pure sample was compared with the one containing impurity phases. It is suggested that the low temperature paramagnetic contribution in Mössbauer spectra of phase pure material may have its origin in some intrinsic phenomena arising from defects or inhomogeneities in crystal structure.
