A fast learning approach for autonomous navigation using a deep reinforcement learning method (2021)

Abstract Deep reinforcement learning‐based methods employ an ample amount of computational power that affects the learning process. This paper proposes a novel approach to speed up the training process and improve the performance of autonomous navigation for a tracked robot. The proposed model named “layer normalization dueling double deep Q‐network” has been trained in a virtual environment and then implemented it to a tracked robot for testing in a real‐world scenario. Depth images have been used instead of RGB images to preserve the temporal information. Features are extracted using convolutional neural networks, and actions are derived using the dueling double deep Q‐network. The input data has been normalized before each convolutional layer, which reduces the covariate shift by 69%. This end‐to‐end network architecture of the proposed model provides stability to the network, relieves the burden of computational cost, and converges in much less number of episodes. Compared with three Q‐variant models, the proposed model demonstrates outstanding performance in terms of episodic reward and convergence rate. The proposed model took 12.8% fewer episodes for training compared to other models.
Validation of UV Spectrophotometric Method for Quantifying Ketoconazole Encapsulated in Ethyl Cellulose Microspheres (2018)

Ketoconazole (KZ) is an antifungal drug used to treat several mycoses. It has poor solubility and causes some adverse effects after its administration. For that reason, it has been included in various drug delivery systems such as polymeric microspheres. Ethyl cellulose is a water‐insoluble polymer widely used to encapsulate drugs because of its safety, good stability, easy fabrication, and cheapness. The amount of drug encapsulated per microspheres mass is a very important parameter to be precisely determined because it defines the mass of particles to be included in a single formulation dose. This work was aimed to validate an ultraviolet (UV) spectrophotometric method to quantify KZ encapsulated in ethyl cellulose microspheres. The KZ‐loaded microspheres were obtained by the emulsion − solvent evaporation method. The UV spectrophotometric method was validated following the ICH Guideline for validation of analytical procedures. The wavelength (247 nm) was selected from the spectrum of KZ (10 μg mL) in dichloromethane. The method was linear within the range 2–12 μg mL (slope: 0.0264; R 2 = 0.9976). The accuracy was 99 ± 3, 98 ± 2, and 101 ± 2% for the low, medium and high range respectively. The intra‐assay relative standard deviation (RSD) was 1.8% while the inter‐assay RSD between days was 1.7%. The method, that is simple, rapid, precise, accurate and reproducible, was successfully applied to determine the content of KZ encapsulated in the ethyl cellulose microspheres.
Moniliasis, 'autoimmune' polyendocrinopathy, and immunologic family study. (1967)

A patient with chronic mucocutaneous moniliasis of 17 years' duration developed bilateral keratitis, hepatitis and steatorrhea, conditions often found in association with coexistent adrenocortical and parathyroid insufficiency. Immunologic studies showed that the patient's serum contained organ-specific antibodies. Further clinical investigation demonstrated adrenal and thyroid insufficiency; parathyroid function was normal. Immunologic abnormalities were also detected in seventeen members of his family, indicating a possible familial predisposition to `autoimmune' disease. A review of the literature suggested that the patient may have an incomplete form of a syndrome consisting primarily of idiopathic Addison's disease, hypoparathyroidism and moniliasis.

Estimation of surface diffusion through porous media (1990)

Abstract A mathematical model is developed to describe steady‐state nonequilibrium surface diffusion of an adsorbing gas through an energetically homogeneous porous medium by assuming that the adsorption isotherm is linear and that the gas‐surface mass transfer can be described by the linear driving force model. Analytical solutions for the model are reported. It is found that the conventional assumption of local thermodynamic equilibrium between the gas and surface phases within the porous medium can seriously underestimate the surface diffusivity when the mass transfer rate is finite. Also, the length of the porous medium becomes a critical variable in that case. Meaningful estimation of surface diffusivity also requires that the gas phase diffusivity through the porous medium be accurately known. The estimated surface diffusivity is model dependent when local thermodynamic equilibrium is not established instantaneously. Modeling surface diffusion can be very complex when the surface is energetically heterogeneous.
The TATA-binding protein participates in TFIIIB assembly on tRNA genes (1992)

The TATA-binding protein TBP has been recently recognized as a general class III transcription factor. Using the gel shift assay to monitor initiation complex assembly on a yeast tRNA gene, we show that TBP is required for the TFIIIC-dependent assembly of TFIIIB. TFIIIB depleted of TBP by a simple chromatographic step does not bind stably to the TFIIIC-tDNA complex. Addition of yeast or human recombinant TBP allows the formation of a TFIIIB-TBP-TFIIIC-tDNA complex. The presence of TBP in the complex was inferred from the effect of anti-TBP antibodies and from the different migration properties of TFIIIB-TBP-tDNA complexes formed with yeast or human TBP.
Numerical modeling of the plasma plume propagation and oxidation during pulsed laser deposition of complex oxide thin films (2020)

Pulsed laser deposition is widely used to synthesize complex oxide thin films with advanced functional properties because of the versatility of the process, although the actual processes and mechanisms that take place are highly dynamic and nontrivial. Detailed understanding of the plume dynamics is required to achieve enhanced control of the growth of complex oxide thin films. However, analytical models of the plasma plume proposed in previous studies, the so-called shockwave model, drag model, and adiabatic thermalization model, only apply to a specific pressure regime and only focus on the propagation of the plasma front. Numerical modeling of the plasma dynamics has previously been pursued for the one-dimensional propagation of a Si plasma plume in a noble background gas. Here we have explored a more generalized numerical model for the dynamics of a ${\mathrm{TiO}}_{2}$ plasma plume by extending to three dimensions, multiple elements in the plasma plume, and including chemical reactions in an oxygen environment without the use of adaptive parameters, other than used for the description of the initial plume shape. Comparison between the simulations and the self-emission measurements of the ${\mathrm{TiO}}_{2}$ plasma plume shows good agreement. Our model enables detailed simulation of the oxidation state of the arriving particles (Ti, TiO, and ${\mathrm{TiO}}_{2}$) on the substrate surface depending on oxygen background pressure. Interestingly, low pressures of about 0.02 mbar result in fast oxygen particles arriving prior to the slower titanium particles, which could significantly influence the oxidation state of the initial substrate surface. The enhanced number of collisions for higher pressures of about 0.1 mbar leads to a large amount of the low-mass oxygen particles coming to a standstill 1--2 cm away from the ablated target. Furthermore, the three-dimensional nature of our model has enabled simulation of the lateral variations in composition of the deposited particles on the substrate surface. Although negligible variations in the Ti:TiO and Ti:${\mathrm{TiO}}_{2}$ ratios are present for high pressures over deposition areas with diameters up to 5 cm, significant variations can be observed for low pressures. These insights could play an important role in upscaling pulsed laser deposition from a scientific laboratory-based scale to an industrial large-area scale.
Using the Black Carbon Particle Mixing State to Characterize the Lifecycle of Biomass Burning Aerosols (2022)

The lifecycle of black carbon (BC)-containing particles from biomass burns is examined using aircraft and surface observations of the BC mixing state for plume ages from ∼15 min to 10 days. Because BC is nonvolatile and chemically inert, changes in the mixing state of BC-containing particles are driven solely by changes in particle coating, which is mainly secondary organic aerosol (SOA). The coating mass initially increases rapidly (<i>k</i><sub>growth</sub> = 0.84 h<sup>-1</sup>), then remains relatively constant for 1-2 days as plume dilution no longer supports further growth, and then decreases slowly until only ∼30% of the maximum coating mass remains after 10 days (<i>k</i><sub>loss</sub> = 0.011 h<sup>-1</sup>). The mass ratio of coating-to-core for a BC-containing particle with a 100 nm mass-equivalent diameter BC core reaches a maximum of ∼20 after a few hours and drops to ∼5 after 10 days of aging. The initial increase in coating mass can be used to determine SOA formation rates. The slow loss of coating material, not captured in global models, comprises the dominant fraction of the lifecycle of these particles. Coating-to-core mass ratios of BC particles in the stratosphere are much greater than those in the free troposphere indicating a different lifecycle.
Implementation of the standard strategy for identification of Ig/TCR targets for minimal residual disease diagnostics in B-cell precursor ALL pediatric patients: Polish experience (2008)

The convergence of Ig/TCR patterns in Polish and European patients indicates that the strategy for Ig/TCR target identification based on standard primers and protocols might be directly used for the construction of Polish standards and recommendations for MRD diagnostics.
La Evaluación continuada en asignaturas numerosas: la experiencia de Fundamentos de Computadores (2009)

La evaluacion continuada en asignaturas numerosas requiere de mucha dedicacion por parte de los profesores y tambien de mecanismos sistematicos que permitan realizarla de forma eficiente. En este articulo se presenta la solucion que se ha adoptado en Fundamentos de computadores para poder hacer un seguimiento lo mas individualizado posible de los alumnos. Si bien el rendimiento academico no ha mejorado significativamente, los resultados de la evaluacion individual mediante examen revelan una fuerte correlacion con los de la evaluacion continuada. Esto puede permitir, en un futuro proximo, la transformacion de los examenes finales en pruebas de validacion de la evaluacion continuada y promover, con ello, una mayor participacion de los alumnos en la misma.
Electrostatic Control of Spontaneous Vesicle Aggregation (1997)

Aqueous mixtures of cationic cetyltrimethylammonium p-toluenesulfonate (CTAT) and anionic sodium dodecylbenzenesulfonate (SDBS) spontaneously form equilibrium “catanionic” vesicles whose charge depends on the relative amounts of each surfactant. Aggregation of these vesicles was induced by incorporating a small concentration of biotin-lipid in the bilayer, followed by addition of streptavidin as a cross-linking receptor. Freeze−fracture transmission electron microscopy shows that almost no aggregation occurred in solutions with no added electrolyte, in which the Debye length was much larger than the dimensions of the streptavidin biotin linkage, about 2.5 nm. Much higher levels of aggregation (multivesicle aggregates) were observed for solutions with 0.1 M NaCl, in which the Debye length was smaller than the linkage dimensions. At an electrolyte concentration of 0.025 M, in which the Debye length is comparable to the linkage dimensions, significant aggregation, which depended on vesicle concentration, occurred. The short-range nature of the specific recognition interaction makes controlling aggregation via electrostatics possible. These results also suggest that electrostatic interactions are at least somewhat responsible for the stability of the spontaneous vesicles against aggregation. As these catanionic vesicles do not flatten upon aggregation, they can maintain an applied osmotic stress across their bilayer much like phospholipid vesicles.
Removal of Cu&lt;sup&gt;2+&lt;/sup&gt; from Aqueous Solution using Fly Ash (2011)

This research aims at investigating the utilization of fly ash as a low-cost adsorbent to remove copper ions from aqueous solutions such as wastewater. Fly ash dosage as well as initial copper ion concentrationtemperature and pH value were varied to find the optimum conditions for Cu 2+ adsorption by fly ash. The results from sorption process showed that the maximum adsorption rate was obtained at 50 mg/L when different dosage of fly ash was added into the solution, and it could be concluded that decreasing the initial concentration of copper ion is beneficial to the adsorption ability of fly ash. With the increase of pH value, the removal rate increased. When pH was 6, the removal rate reached the maximum of 99.60%. When initial copper content was 50 mg/L, pH value was 6, the adsorption capacity of fly ash sample reached 0.98 mg/mg. The main removal mechanisms were assumed to be the adsorption at the surface of the fly ash together with the precipitation from the solution.
Reconfigurable helical antenna based on an origami structure for wireless communication system (2014)

This paper presents a reconfigurable axial mode helical antenna which could be folded and unfolded using rigidly foldable origami structure to work at different resonant frequencies for kinds of wireless systems. Measured results show that the folded state could operate at both 1.82 GHz and 2.14 GHz. And the measured operating frequency for the unfolded state is 860 MHz. The frequency reconfigurability up to 1.28 GHz was achieved, and the height of the folded state could be reduced to 17% of the height of the unfolded state.
In vivotoxicity study of phage lysate in chickens (2009)

1. Bacteriophage (phage) crude lysate of Gram-negative bacteria often contains bacterial debris, including lipopolysaccharides found in the outer membrane of the cell wall, which are potentially toxic. 2. In this study, an in vivo evaluation of the toxicity of a suspension of three phages to control pathogenic Escherichia coli strains in poultry was performed. 3. Eighteen commercial layers, 7 weeks old, were intramuscularly injected with phage lysate (8.21 x 10(4) Endotoxin Units/dose). The control group was injected with sterile Luria Bertani (LB) broth. 4. Bird prostration and decrease in body weight gain and water intake per gram of body weight were observed only on the day of the inoculation in the challenged group. Over the following 6 d, no differences were observed in the chickens' activity. 5. These results support the view that phage crude lysate carrying endotoxins are not toxic for chickens.
Elastic, Piezoelectric, and Dielectric Properties of 0.71Pb(Mg 1/3 Nb 2/3 )O 3 –0.29PbTiO 3 Crystals Obtained by Solid‐State Crystal Growth (2008)

Single crystals with the composition of 0.71Pb(Mg 1/3 Nb 2/3 )O 3 –0.29PbTiO 3 (PMNT29) were grown using the solid‐state crystal growth (SSCG) method. Compared with the conventional Bridgman grown crystals, the SSCG PMNT29 crystals were found to possess comparable piezoelectric, dielectric, and electromechanical properties ( d 33 ∼1500 pC/N, ɛ T 33 / ɛ 0 ∼5400 and k 33 ∼90%), with the same Curie temperature ( T C ) and ferroelectric phase transformation temperature ( T R – T ). The full set of elastic, piezoelectric, and dielectric material constants were determined by the resonance method for the SSCG grown PMNT29 crystals according to IEEE standards and compared with Bridgman grown crystals. The dielectric temperature behavior and the strain field characteristics were investigated, demonstrating excellent performance over the temperature range from room temperature to 95°C. Strain behavior at high electric fields was found to be different from Bridgman growth crystals and believed to be attributed to different domain structures.
Placental rescue reveals a sole requirement for c-Myc in embryonic erythroblast survival and hematopoietic stem cell function (2008)

The c-Myc protein has been implicated in playing a pivotal role in regulating the expression of a large number of genes involved in many aspects of cellular function. Consistent with this view, embryos lacking the c-myc gene exhibit severe developmental defects and die before midgestation. Here, we show that Sox2Cre-mediated deletion of the conditional c-myc(flox) allele specifically in the epiblast (hence trophoectoderm and primitive endoderm structures are wild type) rescues the majority of developmental abnormalities previously characterized in c-myc knockout embryos, indicating that they are secondary defects and arise as a result of placental insufficiency. Epiblast-restricted c-Myc-null embryos appear morphologically normal and do not exhibit any obvious proliferation defects. Nonetheless, these embryos are severely anemic and die before E12. c-Myc-deficient embryos exhibit fetal liver hypoplasia, apoptosis of erythrocyte precursors and functionally defective definitive hematopoietic stem/progenitor cells. Specific deletion of c-myc(flox) in hemogenic or hepatocytic lineages validate the hematopoietic-specific requirement of c-Myc in the embryo proper and provide in vivo evidence to support a synergism between hematopoietic and liver development. Our results reveal for the first time that physiological levels of c-Myc are essential for cell survival and demonstrate that, in contrast to most other embryonic lineages, erythroblasts and hematopoietic stem/progenitor cells are particularly dependent on c-Myc function.
Synchronously pumped optical parametric oscillators using all-solid-state pump lasers (1993)

We discuss recent research on synchronously pumped optical parametric oscillators, outlining some advantages that this technique has over Q-switched pulsed and cw modes of operation. We also describe synchronously pumped devices that use potassium titanyl phosphate and lithium triborate with pump lasers based on second-harmonic generation of the 1047-nm transition in Nd:YLF. Specific emphasis is placed on all-solid-state synchronous pumping of the parametric oscillators and the ability to achieve high efficiencies with relatively low average pump powers. Both doubly and singly resonant devices are discussed with respect to their relative operational merits. We demonstrate broad tuning ranges, from the visible into the IR, and simultaneous four-color operation of the lithium triborate devices with both mode-locked Q-switched and cw mode-locked pump sources.
Review of dielectric behaviour of insulating liquids (2009)

Insulating liquids are widely used in high voltage technological applications including power transformers, circuit breakers and components of pulsed power systems. The breakdown strength of insulating liquids is a key factor which should be taken into account in the design of high voltage systems, and as a result the dielectric properties of these liquids have been intensively studied for many decades. A significant number of research papers published in recent years are devoted to different aspects of the breakdown and breakdown behaviour of dielectric liquids, including the formation of pre-breakdown cavities and streamers, the propagation of streamers, the behaviour of pre-breakdown currents, polarity effects, and the effects of different electrode topologies. However, it is difficult to find any systematic analysis of breakdown properties of the dielectric liquids stressed for either conventional 50/60 Hz AC or DC voltages, or for fast high voltage impulses with rise time shorter than 1 Â¿s. Such Â¿fastÂ¿ high voltage impulses with magnitudes higher than 1 MV are employed in different pulsed power applications, for example for the generation of powerful X-rays or hot plasma. This paper is focused on a literature review of the dielectric properties of available insulating liquids such as mineral oils, bio-degradable oil and synthetic ester liquid under conditions applicable to the power industry and new compact pulsed power systems.
