The Periodontal Ligament: Development, Anatomy and Function (2017)

This paper will explore the origin and development of the periodontal ligament (PDL), its anatomical structure and function. The developmental process and anatomy of the ligament is quite complex and some aspects are still unknown, which will be mentioned, for example the way that ligament lineages develop and are regulated have yet to be clarified. The ground substance will be discussed, as well as the vascular and neural supply, the fibres present, their orientation and the various cell types present in the ligament. The recent advances in PDL stem cell research will also be discussed, which is rapidly growing and can have a huge impact from harnessing these cells to utilise in an array of medical uses. The ligament has several essential functions, which can be highlighted by any deviations from the healthy norm. This can result in retardation of the ligament structure and functional capability. For instance, trauma can result in dental ankylosis, which may disrupt the vital eruptive function of the ligament.

Dynamic Collaborative Business Process Formulation via Ontologised Hierarchical Task Network (HTN) Planning (2009)

Increased trade and globalization has created an increasing need for the dynamic formulation and integration of cross-enterprise collaborative business processes (cBP’s). However, current systems and methodologies, being static in nature, are unable to dynamically formulate cBP’s based on business goals and selection criteria. Much of this stems from the current inability to bridge high level strategic business goals to low-level operational tasks, and the inability to dynamically decompose compound business process tasks into primitive operational tasks for direct Web service execution.In this paper, we demonstrate how the concepts from hierarchical task network (HTN) planning are feasible for dynamically creating cBP task sequences ideal for direct Web service execution. We also establish the rationale behind modeling business-to-business (B2B) collaboration tasks as hierarchical Web ontologies. To demonstrate the achievability of dynamic cBP formulation, we developed the Genesis methodology, which consists of (1) Business-OWL (BOWL) - a B2B hierarchical task Web ontology, and (2) the Genesis algorithm – an extension of the hierarchical task network (HTN) planning algorithm to handle business criteria and control flows commonly found in business processes.
Estimates of heritabilities and genetic correlations for growth and gonad traits in the sea urchin Strongylocentrotus intermedius (2011)

The present study is the first estimate for the sea urchin, Strongylocentrotus intermedius, of genetic parameters for growth and gonad traits during the entire reproductive period. 2165–5764 sea urchins were sampled from 74 to 120 families at six different growth stages. Six hundred individuals were sampled from 20 randomly chosen families at harvest. Coefficients of variation for most growth and gonad traits were high (18.08–78.66%) suggesting a good variation foundation for breeding. Point estimate for heritabilities based on the sire components of variance were moderate to high for test height (0.24–0.39), test diameter (0.21–0.48) and body weight (0.16–0.49). Heritabilities of gonad wet weight, gonad index and gonad moisture at harvest were 0.17, 0.41 and 0.50 respectively (moderate or high). Gonad colour parameters, L* (lightness) and a* (redness) have a heritability of 0, while b* (yellowness) and colour difference ΔE1 and ΔE2 have very similar heritabilities of 0.2, 0.18 and 0.21 respectively. Heritabilities of β-carotene concentration and content were 0.89 and 0.44 respectively. The genetic correlations between the two measured traits ranged from −0.984 to 0.999. Gonad wet weight, L*, b*, β-carotene concentration and β-carotene content had significant positive genetic correlations with all the growth traits. However, gonad index, gonad moisture and colour differences ΔE1 and ΔE2 had significant negative genetic correlations with growth traits. The present study indicates that growth, gonad yield and most gonad quality traits could be improved by selection with moderate to high potential. Indirect selection should be applied on gonad traits using growth traits as secondary traits. The present study provides important theoretical guidance for future selective breeding programmes for S. intermedius.
Use of DNA Microarrays for Rapid Genotyping of TEM Beta-Lactamases That Confer Resistance (2004)

Standard clinical procedures for pathogen resistance identification are laborious and usually require 2 days of cultivation before the resistance can be determined unequivocally. In contrast, clinicians and patients face increasing threats from antibiotic-resistant pathogenic bacteria in terms of their frequencies and levels of resistance. A major class of microbial resistance stems from the occurrence of beta-lactamases, which, if mutated, can cause the severe extended-spectrum beta-lactamase (ESBL) or inhibitor-resistant TEM (IRT) phenotype, which cause resistance to extended-spectrum cephalosporins, monobactams, and beta-lactamase inhibitors. We describe an oligonucleotide microarray for identification of the single nucleotide polymorphisms (SNPs) of 96% of the TEM beta-lactamase variants described to date which are related to the ESBL and/or IRT phenotype. The target DNA, originating from Escherichia coli, Enterobacter cloacae, and Klebsiella pneumoniae cells isolated from clinical samples, was amplified and fluorescently labeled by PCR with consensus primers in the presence of cyanine 5-labeled nucleotides. The total assay, including PCR, hybridization, and image analysis, could be performed in 3.5 h. The microarray results were validated by standard clinical procedures. The microarray outperformed the standard procedures in terms of assay time and the depth of information provided. In conclusion, this array offers an attractive option for the identification and epidemiologic monitoring of TEM beta-lactamases in the routine clinical diagnostic laboratory.
Copper Substitution and Noise Reduction in Brake Pads: Graphite Type Selection (2012)

Graphite is commonly used in brake pads. The use of graphite powder has the main goal of solid state lubrication and friction coefficient stabilization. In this article results on resin bonded brake pads with focus on noise performance and heat dissipation are presented. Experimental tests are based on model friction materials with a known formulation and a reduced number of components for a better identification of the role of the graphite type. Results clearly indicate that both noise performance and thermal conductivity are strongly affected by the type of graphite. Guidelines for the selection of graphite types for optimized friction materials are given.

Removal of CrO42–, a Nonradioactive Surrogate of 99TcO4–, Using LDH–Mo3S13 Nanosheets (2022)

Removal of chromate (CrO<sub>4</sub><sup>2-</sup>) and pertechnetate (TcO<sub>4</sub><sup>-</sup>) from the Hanford Low Activity Waste (LAW) is beneficial as it impacts the cost, life cycle, operational complexity of the Waste Treatment and Immobilization Plant (WTP), and integrity of vitrified glass for nuclear waste disposal. Here, we report the application of [Mo<sup>IV</sup><sub>3</sub>S<sub>13</sub>]<sup>2-</sup> intercalated layer double hydroxides (LDH-Mo<sub>3</sub>S<sub>13</sub>) for the removal of CrO<sub>4</sub><sup>2-</sup> as a surrogate for TcO<sub>4</sub><sup>-</sup>, from ppm to ppb levels from water and a simulated LAW off-gas condensate of Hanford's WTP. LDH-Mo<sub>3</sub>S<sub>13</sub> removes CrO<sub>4</sub><sup>2-</sup> from the LAW condensate stream, having a pH of 7.5, from ppm (∼9.086 × 10<sup>4</sup> ppb of Cr<sup>6+</sup>) to below 1 ppb levels with distribution constant (<i>K</i><sub>d</sub>) values of up to ∼10<sup>7</sup> mL/g. Analysis of postadsorbed solids indicates that CrO<sub>4</sub><sup>2-</sup> removal mainly proceeds by reduction of Cr<sup>6+</sup> to Cr<sup>3+</sup>. This study sets the first example of a metal sulfide intercalated LDH for the removal of CrO<sub>4</sub><sup>2-</sup>, as relevant to TcO<sub>4</sub><sup>-</sup>, from the simulated off-gas condensate streams of Hanford's LAW melter which contains highly concentrated competitive anions, namely F<sup>-</sup>, Cl<sup>-</sup>, CO<sub>3</sub><sup>2-</sup>, NO<sub>3</sub><sup>-</sup>, BO<sub>3</sub><sup>3-</sup>, NO<sub>2</sub><sup>-</sup>, SO<sub>4</sub><sup>2-</sup>, and B<sub>4</sub>O<sub>7</sub><sup>2-</sup>. LDH-Mo<sub>3</sub>S<sub>13</sub>'s remarkable removal efficiency makes it a promising sorbent to remediate CrO<sub>4</sub><sup>2-</sup>/TcO<sub>4</sub><sup>-</sup> from surface water and an off-gas condensate of nuclear waste.
<title>Comparative study of laser action on normal and atherosclerotically damaged vessel tissue in broad spectrol range</title> (1994)

To study a possibility of selective laser action on atherosclerotic plaques and normal vessel wall a set of laboratory experiments was performed. We used XeCl-laser with a Raman shifting cell and Nd-YAG laser with a frequency doubler, tripler, and quadrupler. It allows us to compare the results of laser action on tissue in a broad spectral range. The laboratory setups permit us to vary parameters of laser radiation such as pulse repetition rate, duration, energy, and power density. All samples were subjected to detailed morphological study. In particular, experiments with XeCl-laser demonstrate that the specific vaporization energy decreases when the laser energy increases. The penetration depth of laser radiation was considerably less than is to be expected from the measurement of absorption factor at 308 nm. Moreover, the absorption spectrum of the tissue after irradiation was absolutely different from the initial tissue absorption spectrum. Therefore, the two-photon processes play the main part in the interaction of high-power laser-light with tissue. Thus the laser pulse duration is to be considered as one of the most important parameters in this case. It is shown also that IR radiation at 1.06 mkm is quite effective to penetrate into calcified plaques. Laser angioplasty is still to be considered as a promising technique for treatment of vascular diseases. However, the discussion about the type of laser to be used for this purpose has not yet been finished.

Enhanced Rhizosphere Bacterial Population in an Abandoned Copper Mined-out Area Planted with Jatropha Interspersed with Selected Indigenous Tree Species (2013)

Rehabilitation was conducted in an abandoned copper mined-out area in Mogpog, Marinduque by interplanting Jatropha curcas, a biodiesel source and potential phytoremediator, with different reforestation tree species, Pterocarpus indicus, Cassia spectabilis, Lagerstroemia speciosa and Bauhinia purpurea. The effect of the diversification treatment on the rhizosphere bacterial population, known to promote growth of host plant, was analyzed within a fifteen-month period (August 2007 to November 2008). The number of cultivable soil bacteria on-site prior to planting was very low (&lt;0.01 to 2 x 103 CFU per g) owing to soil’s acidity (pH 5) and poorly nourished condition. Higher bacterial population was observed from Jatropha rhizosphere than soil without vegetation. Bacterial population also varied with diversification treatments. Highest populations (7.3 x 104 to 1.3 x 105 CFU per g) of Cu-, Pb- and Zn resistant bacteria were observed where in Jatropha was interplanted with Pterocarpus, Cassia, and Lagerstroemia. It appears that such treatment enhanced the population of heavy metal-resistant rhizosphere bacteria in Jatropha indicative of its potential in bioremediation. Randomly selected isolates were identified as Arthrobacter oxydans, Klebsiella variicola and Bacillus spp, which are all common soil bacteria. Rehabilitation of abandoned, mined-out areas can thus be naturally promoted by diversifying plants being introduced in such sites as this would enhance rhizosphere bacterial population.
Stand-Alone Three-Dimensional Optical Tweezers Based on Fibred Bowtie Nanoaperture (2014)

We study optical trapping of small particles based on the use of a bowtie nanoaperture antenna (BNA) engraved at the end of a metal-coated near-field optical microscope tip. Within the obtained light confinement, a 3-D trapping of latex nanoparticles is studied and quantified as a function of the incident light power. Good agreement between experimental and numerical results is obtained for a BNA operating in water at (λ = 1064 nm) that faithfully traps 250-nm-radius latex particles. Further numerical investigations are performed to study the dynamic of the trapping process in comparison with experimental results. In addition, numerical results for R = 100 nm and R = 30 nm-radii latex particles are presented and show that such a configuration has the potential to trap latex particles as small as 30 nm in radius.

Diversity and Global Distribution of Viruses of the Western Honey Bee, Apis mellifera (2020)

In the past centuries, viruses have benefited from globalization to spread across the globe, infecting new host species and populations. A growing number of viruses have been documented in the western honey bee, <i>Apis mellifera</i>. Several of these contribute significantly to honey bee colony losses. This review synthetizes the knowledge of the diversity and distribution of honey-bee-infecting viruses, including recent data from high-throughput sequencing (HTS). After presenting the diversity of viruses and their corresponding symptoms, we surveyed the scientific literature for the prevalence of these pathogens across the globe. The geographical distribution shows that the most prevalent viruses (deformed wing virus, sacbrood virus, black queen cell virus and acute paralysis complex) are also the most widely distributed. We discuss the ecological drivers that influence the distribution of these pathogens in worldwide honey bee populations. Besides the natural transmission routes and the resulting temporal dynamics, global trade contributes to their dissemination. As recent evidence shows that these viruses are often multihost pathogens, their spread is a risk for both the beekeeping industry and the pollination services provided by managed and wild pollinators.
Metal Domain Size Dependent Electrical Transport in Pt-CdSe Hybrid Nanoparticle Monolayers (2015)

Thin films prepared of semiconductor nanoparticles are promising for low-cost electronic applications such as transistors and solar cells. One hurdle for their breakthrough is their notoriously low conductivity. To address this, we precisely decorate CdSe nanoparticles with platinum domains of one to three nanometers in diameter by a facile and robust seeded growth method. We demonstrate the transition from semiconductor to metal dominated conduction in monolayered films. By adjusting the platinum content in such solution-processable hybrid, oligomeric nanoparticles the dark currents through deposited arrays become tunable while maintaining electronic confinement and photoconductivity. Comprehensive electrical measurements allow determining the reigning charge transport mechanisms.
Radio Remote Head Clustering with Affinity Propagation Algorithm in C-RAN (2019)

The optimal number of clusters (K) differs depending on the radio remote head (RRH) density. This paper verifies that the K values cannot be met by the conventional affinity propagation (AP) clustering algorithm. In an ultra-dense network (UDN) environment, the density of RRH is a very important factor for the bender because it is directly related to the cost of configuring the wireless communication network. Likewise, in order to provide the optimal communication environment to the user in the UDN environment, it is necessary to enable flexible clustering according to changing channel environment by utilizing semi-dynamic clustering technology. As a result, we propose an AP algorithm that finds a better K value than the conventional method. To this end, the proposed algorithm additionally utilizes a non-coordinated multi-point (CoMP) interference power that varies depending on the RRH density, user position, and the variations in propagation channel. The simulation results show that the proposed algorithm shows a better average capacity than the conventional algorithm.
Influence of the Rapid Thermal Annealing on the Properties of Thin a-Si Films (2004)

The variation of the structure, morphology and the electrical properties of thin amorphous silicon films caused by Rapid Thermal Annealing is studied. The films annealed at 1200degreesC for 2 minutes change their structure to polycrystalline and as a result their resistivity decreases by 4 orders of magnitude. Due to the small thickness of the as deposited amorphous silicon the obtained poly-Si is strongly irregular and has many discontinuities in its texture.
Design of defect spins in piezoelectric aluminum nitride for solid-state hybrid quantum technologies (2016)

Spin defects in wide-band gap semiconductors are promising systems for the realization of quantum bits, or qubits, in solid-state environments. To date, defect qubits have only been realized in materials with strong covalent bonds. Here, we introduce a strain-driven scheme to rationally design defect spins in functional ionic crystals, which may operate as potential qubits. In particular, using a combination of state-of-the-art ab-initio calculations based on hybrid density functional and many-body perturbation theory, we predicted that the negatively charged nitrogen vacancy center in piezoelectric aluminum nitride exhibits spin-triplet ground states under realistic uni- and bi-axial strain conditions; such states may be harnessed for the realization of qubits. The strain-driven strategy adopted here can be readily extended to a wide range of point defects in other wide-band gap semiconductors, paving the way to controlling the spin properties of defects in ionic systems for potential spintronic technologies.
Micelle Formation and Stabilization of Metal Nanoparticles in Aqueous Solutions of Diblock Copolymers with Monomethyl Ether of Poly(Ethylene Oxide) and Poly(Acrylic Acid) (2011)

Abstract Double-hydrophilic block copolymers including monomethyl ether of poly(ethylene oxide) and poly(acrylic acid) (MEPEO-b-PAAc) with the different ratios of polymer blocks are synthesized by the matrix block-copolymerization and characterized. The intramolecular complex formation (IntraPC) between polymer blocks in MEPEO-b-PAAc at low pH (protonated MEPEO-b-PAAc) is established. It causes the MEPEO-b-PAAc intense micellization in aqueous solutions at pH ≤ 4. Water solutions of MEPEO-b-PAAc copolymers are used for the synthesis of silver nanoparticles. The stabilizing property of MEPEO-b-PAAc solutions by the interaction with the colloid dispersions of silver nanoparticles is shown.

Application of the red fluorescent protein mCherry in mycelial labeling and organelle tracing in the dermatophyte Trichophyton mentagrophytes (2018)

Trichophyton mentagrophytes is a fungus that causes skin disease in humans and other animals worldwide. Studies on molecular biology and fluorescent labeling of the fungus are limited. Here, we applied mCherry for the first time in T. mentagrophytes to label the fungus and its organelles. We constructed four expression vectors of mCherry or mCherry fusions containing a variety of resistance markers and promoters, which were then integrated, together with two previous mCherry expression vectors, in T. mentagrophytes via Agrobacterium tumefaciens-mediated transformation (AtMT). The resulting transformants emitted bright red fluorescence. We used the histone protein H2B and the peroxisome targeting signal 1 (PTS1) peptide to target the nucleus and peroxisomes, respectively, in T. mentagrophytes. In the transformants expressing mCherry-fused H2B, the fluorescence was distinctly localized to the nuclei in hyphae, spores and the fungal cells in infected animal tissue. In the T. mentagrophytes transformants where the peroxisome was targeted, the mCherry was present as small dots (0.2-1 μm diameter) throughout the spores and the hyphae. We also constructed a T. mentagrophytes AtMT library containing more than 1000 hygromycin-resistant transformants that were genetically stable. Our results provide useful tools for further investigations on molecular pathogenesis of T. mentagrophytes.
