Bone mechanics and cell populations: mathematical description and parametric study of the model
No full textIn this paper we study a recently proposed mathematical model for the description of the mechanics of bone as well as bone remodeling processes and bone cell populations dynamics. We investigate the biological meaning and a suitable value for the numerical parameters of the model. To do so, we compare biological data with a systematic numerical investigation of the model. We also propose some corrections to the original model aimed at better describing the observed phenomena

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
CoNiZn and CoNiFe nanoparticles: synthesis, physical characterization, and in vitro cytotoxicity evaluations
No full textThe polyol method has been used to synthesize CoNiFe and CoNiZn alloy nanoparticles (NPs). The magnetic characteristics of the products have been measured by vibration sample magnetometry (VSM) analysis. At the same time, the microstructure and morphology were inspected by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. Magnetic measurement of samples by the VSM indicated that samples have soft ferromagnetic behavior. Spherical-shaped grains for samples were confirmed by the SEM. MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and lactate dehydrogenase (LDH) assays were used to determine the cytotoxic effects of the synthesized NPs. Cytotoxic evaluations showed that treatment with 25 to 400 μg/mL of CoNiZn and CoNiFe NPs exerted a significant time-and concentration-dependent toxicity in MCF7 and HUVEC cells and markedly enhanced the LDH leakage after 48 h of exposure (p < 0.05 compared with untreated cells). Furthermore, NPs with concentrations higher than 12.5 μg/mL induced evident morphological changes in the studied cell lines. Treatment with 12.5 μg/mL of CoNiZn and CoNiFe NPs was safe and did not affect normal human cell survival. The results of in vitro cytotoxicity assessments show promise in supporting the suitability of the synthesized NPs to build high-performance theranostic nanoplatforms for simultaneous cancer imaging and therapy without affecting normal human cells
Quantum storage of a photonic polarization qubit in a doped crystal
No full textWe report storage of photonic polarization qubits in a crystal. The average conditional fidelity of retrieved qubits exceeds 95% for a mean photon number μ = 0.4, higher than the classical benchmark proving the quantum nature of the storage.</p
Quantum storage of a photonic polarization qubit in a solid
No full textWe report on the quantum storage and retrieval of photonic polarization quantum bits onto and out of a solid state storage device. The qubits are implemented with weak coherent states at the single photon level, and are stored for a predetermined time of 500 ns in a praseodymium doped crystal with a storage and retrieval efficiency of 10%, using the atomic frequency comb scheme. We characterize the storage by using quantum state tomography, and find that the average conditional fidelity of the retrieved qubits exceeds 95% for a mean photon number μ=0.4. This is significantly higher than a classical benchmark, taking into account the Poissonian statistics and finite memory efficiency, which proves that our crystal functions as a quantum storage device for polarization qubits. These results extend the storage capabilities of solid state quantum light matter interfaces to polarization encoding, which is widely used in quantum information science.</p

Note: — Popov (1940) described this taxon as a variety of Phlomoides laciniata (former Eremostachys laciniata var. labiosiformis Popov), but based on the size of upper lip of corolla and calyx, Knorring (1954) recognized this variety as a distinct species, i.e. Eremostachys labiosiformis (Popov) Knorring (= Phlomoides labiosiformis). Recently, Ranjbar & Mahmoudi (2017) described P. semnanensis as a new species allied to P. labiosiformis. They mentioned that P. semnanensis differs from P. labiosiformis by a calyx 15–18 mm (versus 20–28 mm) long and corolla 26–29 mm (versus 35–40 mm) long. However, based on the photos of P. semnanensis in its natural habitat, it seems that the plants were collected at anthesis, and the smaller flower size is due to early collection date and immature plants. Therefore, P. semnanica is considered here as a synonym of P. labiosiformis.Published as part of Almasi, Maryam, Salmaki, Yasaman & Xiang, Chun-Lei, 2022, Typification and taxonomic remarks on some names in Phlomoides (Phlomideae: Lamiaceae), pp. 87-94 in Phytotaxa 570 (1) on page 92, DOI: 10.11646/phytotaxa.570.1.8, http://zenodo.org/record/725156
