Wall Deposition of Radon Progeny and Particles in a Spherical Chamber (1997)

In indoor and mining environments, deposition to "plate-out" of radon progeny onto walls occurs simultaneously with the attachment of progeny of airborne particles.Attachment and plate-out processes affect the atmosphere in which radon exposure takes place by reducing concentrations and shifting activity size distributions.Deposition of fine particles on paintings and other art objects is also a concern in museums.Here we describe plate-out measurements of radon progeny and aerosol particles in a spherical chamber under controlled laboratory conditions.The temperature and velocity profiles in still and turbulent air were monitored.A laboratory mixer with variable speeds and speed control was used to increase turbulence in the chamber.During mixing, air velocity was detected when rotational speeds were higher than 500 rpm.Monodisperse silver aerosols and polystyrene latex particles in the size range of 5 nm to 2 p m were used in the deposition study.Nanometer particles between 0.88 to 1.80 nm were generated by passing 2 2 0 ~n gas into the chamber and letting the gas decay into '12Pb.The deposition rates of particles and radon progeny ('12Pb) in the chamber were determined by monitoring the concentration decay of the aerosol as a function of time.Our data confirmed that the homogeneous turbulence model can be used to describe the wall deposition rate in still and mixing conditions.Higher deposition rates were observed during increased air mixing.Higher rates were more significant for particles smaller than 1.0 pm, indicating that the turbulence produced by mixing increased the turbulent diffusional deposition.The coefficient of eddy diffusivity was predicted by the mass transfer equation.The coefficient was also reasonably predicted from a technique using velocity measurement and from an energy dissipation equation.
NOVEL APERTURE-COUPLED MICROSTRIP-LINE FEED FOR CIRCULARLY POLARIZED PATCH ANTENNA (2014)

A wideband circularly polarized patch antenna is proposed. The wide impedance and axial ratio bandwidths are achieved by the proposed feeding mechanism, which entails the use of a circular microstrip line coupling through four -shaped slots to generate four sequentially phased sources to excite the single layer patch antenna. The proposed antenna can provide an SWR bandwidth of over 16.5% (for SWR < 1.5) and an axial-ratio bandwidth of 13.3% (for AR < 3 dB). The performance of the antenna has been confirmed by both measurement and simulation. The antenna gain is enhanced and backlobe radiation is reduced by placing a reflector at an optimized location.
Large magnetic moment enhancement and extraordinary Hall effect in Co/Pt superlattices (2000)

High quality (111) and (100) oriented Co/Pt superlattices have been prepared using the magnetron sputtering technique. The extraordinary Hall effect and magnetic properties in a series of these Co/Pt superlattices have been studied. We have established the existence of a large enhanced moment at the Co/Pt interfaces. Tensile strain in the magnetic layers is found to dominate the perpendicular magnetic anisotropy for the (111) orientation. From a systematic variation of the Co layer thickness we have determined that the extraordinary Hall resistivity is dominated by interface scattering. Further, large deviations from the commonly used scaling relations linking the extraordinary Hall resistivity and the ordinary resistivity are observed. These are discussed within a model proposed by Zhang.
Evolution programs for job-shop scheduling (2002)

This paper explains how to minimize a makespan of the job shop scheduling problem using evolutionary programs. So the job shop scheduling problem is among the hardest combinatorial problems. Not only is it NP complete but it is one of the worst NP complete class members, but for better performance it is very important to develop an efficient representational scheme and effective genetic operators. Our objective is to improve performance of the evolutionary programs based approach to job-shop scheduling problems by creating a new representation of the chromosome where we integrate the precedence constraint, and the new genetic operators associated with this original representation.
SECOND AND THIRD SEASON QUaD COSMIC MICROWAVE BACKGROUND TEMPERATURE AND POLARIZATION POWER SPECTRA (2009)

We report results from the second and third seasons of observation with the QUaD experiment. Angular&#13;\npower spectra of the cosmic microwave background are derived for both temperature and polarization at&#13;\nboth 100 GHz and 150 GHz, and as cross-frequency spectra. All spectra are subjected to an extensive&#13;\nset of jackknife tests to probe for possible systematic contamination. For the implemented data cuts and&#13;\nprocessing technique such contamination is undetectable. We analyze the difference map formed between the&#13;\n100 and 150 GHz bands and find no evidence of foreground contamination in polarization. The spectra are&#13;\nthen combined to form a single set of results which are shown to be consistent with the prevailing LCDM&#13;\nmodel. The sensitivity of the polarization results is considerably better than that of any previous experiment—&#13;\nfor the first time multiple acoustic peaks are detected in the E-mode power spectrum at high significance.
Near-UV phosphorescent emitters: N-heterocyclic platinum(ii) tetracarbene complexes (2009)

Although examples of nickel(ii), palladium(ii) and platinum(ii) N-heterocyclic tetracarbene complexes are known in the literature, particularly platinum(ii) tetracarbene complexes are rare. We developed a new synthetic route via biscarbene acetate complexes, which make homoleptic as well as heteroleptic platinum(ii) tetracarbene complexes accessible. The reported photoluminescence data show that these complexes have good quantum yields and photostability and are a promising class of emitters for PhOLEDs. Characterization of the compounds includes a solid-state structure of the homoleptic complex bis(1,1'-diisopropyl-3,3'-methylenediimidazoline-2,2'-diylidene)platinum(ii) dibromide.
Influence of Binary Curing System on the Nitrile Rubber Mechanical Properties (2016)

Summary The effect of different sulphur‐based curing systems on the nitrile rubber mechanical properties was assessed. High acrylonitrile content nitrile rubber compositions were prepared with different amounts of N‐cyclohexyl‐2‐benzothiazole‐sulfenamide (CBS), tetramethylthiuram disulfide (TMTD) and sulphur. The following tests were conducted: crosslink density, hardness, and stress‐strain tests. Scanning electron microscopy, infrared and NMR spectroscopies, and statistical analyses were carried out to bring new interesting aspects to this topic. Crosslink density was statistically influenced by the amount of TMTD and sulphur, whereas no significance was observed for CBS content. Tensile strength was above the optimum point regarding the crosslink density. Time‐dependent exudation of TMTD was observed when added in higher concentration.
Base Station Operation and User Association Mechanisms for Energy-Delay Tradeoffs in Green Cellular Networks (2011)

Energy-efficiency, one of the major design goals in wireless cellular networks, has received much attention lately, due to increased awareness of environmental and economic issues for network operators. In this paper, we develop a theoretical framework for BS energy saving that encompasses dynamic BS operation and the related problem of user association together. Specifically, we formulate a total cost minimization that allows for a flexible tradeoff between flow-level performance and energy consumption. For the user association problem, we propose an optimal energy-efficient user association policy and further present a distributed implementation with provable convergence. For the BS operation problem (i.e., BS switching on/off), which is a challenging combinatorial problem, we propose simple greedy-on and greedy-off algorithms that are inspired by the mathematical background of submodularity maximization problem. Moreover, we propose other heuristic algorithms based on the distances between BSs or the utilizations of BSs that do not impose any additional signaling overhead and thus are easy to implement in practice. Extensive simulations under various practical configurations demonstrate that the proposed user association and BS operation algorithms can significantly reduce energy consumption.
A novel approach to 2D drawings-based reconstruction of 3D building digital models (2015)

There is an opportunity to significantly impact building energy efficiency through BIM-enabled, simulation-intensive, cost-effective renovation actions. One major hurdle however is the lack of 3D digital models for the majority of existing buildings. Cost-effective and widely applicable methods and tools are required for the reconstruction of 3D digital models from available information. In this scope, this paper presents ongoing research about the development of tools for semi-automated 3D building model generation from 2D scanned plans. More specifically, the paper focuses on the description of an innovative reconstruction process based on a combination of automated processing and punctual, softwareassisted, user intervention. The paper also gives an account of the experiments lead with a research prototype, tested on 90 real architectural floor plans. The results are encouraging and suggest that the mix of software-assistance and focused human intervention may be the best trade-off to upgrade the quality of the generated models and to achieve cost-effectiveness.

Significant enhancement of micropollutant photocatalytic degradation using a TiO2 nanotube array photoanode based photocatalytic fuel cell (2018)

This study evaluated the application of a membrane-free photocatalytic fuel cell composed of a TiO2 nanotube array photoanode and a Cu cathode, i.e. TNA-Cu PFC system, for micropollutant removal from water. Significantly enhanced removal of a commonly present aqueous micropollutant 4-chloro-2-methylphenoxyacetic acid (MCPA) was obtained in this TNA-Cu PFC system: the TNA-Cu PFC system achieved better MCPA degradation compared to the conventional photocatalytic method using the same catalyst. In the TNA-Cu PFC system, the MCPA degradation was largely promoted under acidic conditions, indicating this as an important operational condition. The enhancement of MCPA degradation in the TNA-Cu PFC system involved better e−/h+ separation and generation of other oxidants: in conventional photocatalytic process, hydroxyl radicals in liquid phase contributed to 93.7% MCPA degradation while only 2.4% MCPA degradation was mediated by other oxidants like O2−, H2O2, HO2; for MCPA degradation in the TNA-Cu PFC system, the contribution of hydroxyl radicals in the liquid phase decreased to 83.6%, while contribution of other oxidants like O2−, H2O2, HO2 increased to 15.3%. This change in MCPA degradation mechanisms was confirmed via degradation intermediates analysis by LC-MS/MS. The study on the effect of electrolyte concentration suggests that when operated under acidic conditions, addition of electrolyte is not required. The TNA-Cu PFC system was shown to work well in the presence of up to 15 mg/L natural organic matter (originating from two large rivers), high amounts of common inorganic ions, and even in WWTP effluent. The TNA-Cu PFC system also exhibited relatively good stability after several cycles of repeated use. The obtained results demonstrated that this is an adequate system for micropollutant removal from water at various places in the water cycle, i.e. as polisher of WWTP effluents before discharge or for cleaning intake water before producing drinking water.
Cardiovascular homeostasis dependence on MICU2, a regulatory subunit of the mitochondrial calcium uniporter (2017)

Comparative analyses of transcriptional profiles from humans and mice with cardiovascular pathologies revealed consistently elevated expression of <i>MICU2</i>, a regulatory subunit of the mitochondrial calcium uniporter complex. To determine if <i>MICU2</i> expression was cardioprotective, we produced and characterized <i>Micu2</i><sup><i>-/-</i></sup> mice. Mutant mice had left atrial enlargement and <i>Micu2</i><sup><i>-/-</i></sup> cardiomyocytes had delayed sarcomere relaxation and cytosolic calcium reuptake kinetics, indicating diastolic dysfunction. RNA sequencing (RNA-seq) of <i>Micu2</i><sup><i>-/-</i></sup> ventricular tissues revealed markedly reduced transcripts encoding the apelin receptor (<i>Micu2</i><sup><i>-/-</i></sup> vs. wild type, <i>P</i> = 7.8 × 10<sup>-40</sup>), which suppresses angiotensin II receptor signaling via allosteric transinhibition. We found that <i>Micu2</i><sup><i>-/-</i></sup> and wild-type mice had comparable basal blood pressures and elevated responses to angiotensin II infusion, but that <i>Micu2</i><sup><i>-/-</i></sup> mice exhibited systolic dysfunction and 30% lethality from abdominal aortic rupture. Aneurysms and rupture did not occur with norepinephrine-induced hypertension. Aortic tissue from <i>Micu2</i><sup><i>-/-</i></sup> mice had increased expression of extracellular matrix remodeling genes, while single-cell RNA-seq analyses showed increased expression of genes related to reactive oxygen species, inflammation, and proliferation in fibroblast and smooth muscle cells. We concluded that <i>Micu2</i><sup><i>-/-</i></sup> mice recapitulate features of diastolic heart disease and define previously unappreciated roles for <i>Micu2</i> in regulating angiotensin II-mediated hypertensive responses that are critical in protecting the abdominal aorta from injury.
Pro‐Angiogenic Capacity of MMP‐9 Produced by Different Types of Inflammatory Leukocytes is Determined by the Levels of TIMP‐1 Complexed with the MMP‐9 Proenzyme (2012)

By delivering a potent matrix metalloproteinase, MMP‐9, inflammatory neutrophils and macrophages (mε) play an important role in tumor angiogenesis. We have previously demonstrated that uniquely high angiogenic capacity of neutrophil MMP‐9 (nMMP‐9) is determined by its TIMP‐free status. Herein, we compared biochemically and functionally nMMP‐9 with the MMP‐9 produced by monocytic cells, including monocytes and innate (M0), tumor suppressing (M1), and tumor promoting (M2) macrophages (mε). Angiogenic potential of a specific inflammatory leukocyte type was related to gene and protein expression levels of TIMP‐1 and MMP‐9, ultimately determining how much TIMP‐1 is complexed with secreted MMP‐9. Resembling neutrophils that release TIMP‐free MMP‐9, M2 mε produce MMP‐9 complexed with very low amounts of TIMP‐1. Correspondingly, M2 mε induced relatively high levels of neovascularization, yielding only to neutrophils in their angiogenic potential. Low TIMP‐1/MMP‐9 ratios inversely correlated with the high proteolytic activity of nMMP‐9 and M2 mε MMP‐9 in a substrate cleavage assay. Finally, the lack of TIMP‐1 in nMMP‐9 and low TIMP‐1 burden in M2 mε MMP‐9 were functionally linked to their high capacity to induce new blood vessel formation, thereby highlighting a biochemical mechanism underlying unique angiogenic potential of MMP‐9 delivered by inflammatory neutrophils and pro‐tumorigenic macrophages.
Genome-wide copy number variant screening of Saudi schizophrenia patients reveals larger deletions in cases versus controls (2023)

Runs of homozygosity (ROHs) were analyzed across the genome to investigate correlation with schizophrenia risk. While rates and sizes of these ROHs were similar in cases and controls, we identified 10 regions where multiple cases had ROHs and controls did not.
Hierarchical Spatial Aggregation for Level-of-Detail Visualization of 3D Thematic Data (2018)

Thematic maps are a common tool to visualize semantic data with a spatial reference. Combining thematic data with a geometric representation of their natural reference frame aids the viewer’s ability in gaining an overview, as well as perceiving patterns with respect to location; however, as the amount of data for visualization continues to increase, problems such as information overload and visual clutter impede perception, requiring data aggregation and level-of-detail visualization techniques. While existing aggregation techniques for thematic data operate in a 2D reference frame (i.e., map), we present two aggregation techniques for 3D spatial and spatiotemporal data mapped onto virtual city models that hierarchically aggregate thematic data in real time during rendering to support on-the-fly and on-demand level-of-detail generation. An object-based technique performs aggregation based on scene-specific objects and their hierarchy to facilitate per-object analysis, while the scene-based technique aggregates data solely based on spatial locations, thus supporting visual analysis of data with arbitrary reference geometry. Both techniques can apply different aggregation functions (mean, minimum, and maximum) for ordinal, interval, and ratio-scaled data and can be easily extended with additional functions. Our implementation utilizes the programmable graphics pipeline and requires suitably encoded data, i.e., textures or vertex attributes. We demonstrate the application of both techniques using real-world datasets, including solar potential analyses and the propagation of pressure waves in a virtual city model.

Postechiella marina gen. nov., sp. nov., isolated from seawater (2011)

A Gram-staining-negative, strictly aerobic, non-motile, yellow-pigmented bacterium, designated strain M091(T), was isolated from seawater at Damupo beach in Pohang, Republic of Korea, and investigated using a polyphasic taxonomic approach. The novel strain grew optimally at 25 °C, pH 7.0-8.0, and in the presence of 3% (w/v) NaCl. In a phylogenetic analysis based on 16S rRNA gene sequences, strain M091(T) formed a lineage within the family Flavobacteriaceae that was distinct from the most closely related genera of Flaviramulus (95.1% sequence similarity), Algibacter (94.9-93.9%), Mariniflexile (94.8-94.2%), Winogradskyella (94.8-93.2%), Lacinutrix (94.7-93.8%) and Tamlana (94.7-92.9%). The polar lipid profile of the novel strain comprised phosphatidylethanolamine, two unidentified aminolipids, one unidentified phospholipid and seven unidentified lipids. The predominant cellular fatty acids were iso-C(15:0) (20.5%), iso-C(17:0) 3-OH (15.4%), iso-C(15:0) 3-OH (12.4%), C(15:0) (10.9%) and iso-C(15:1) G (9.9%). The genomic DNA G+C content of strain M091(T) was 34.4 mol% and the major respiratory quinone was MK-6. Based on phenotypic and genotypic data, strain M091(T) represents a new genus and novel species in the family Flavobacteriaceae, for which the name Postechiella marina gen. nov., sp. nov. is proposed. The type strain of the type species is M091(T) (=KCTC 23537(T)=JCM 17630(T)).
Effect of sea salt aerosol on tropospheric bromine chemistry (2019)

Abstract. Bromine radicals influence global tropospheric chemistry by depleting ozone and by oxidizing elemental mercury and reduced sulfur species. Observations typically indicate a 50 % depletion of sea salt aerosol (SSA) bromide relative to seawater composition, implying that SSA debromination could be the dominant global source of tropospheric bromine. However, it has been difficult to reconcile this large source with the relatively low bromine monoxide (BrO) mixing ratios observed in the marine boundary layer (MBL). Here we present a new mechanistic description of SSA debromination in the GEOS-Chem global atmospheric chemistry model with a detailed representation of halogen (Cl, Br, and I) chemistry. We show that observed levels of SSA debromination can be reproduced in a manner consistent with observed BrO mixing ratios. Bromine radical sinks from the HOBr + S(IV) heterogeneous reactions and from ocean emission of acetaldehyde are critical in moderating tropospheric BrO levels. The resulting HBr is rapidly taken up by SSA and also deposited. Observations of SSA debromination at southern midlatitudes in summer suggest that model uptake of HBr by SSA may be too fast. The model provides a successful simulation of free-tropospheric BrO in the tropics and midlatitudes in summer, where the bromine radical sink from the HOBr + S(IV) reactions is compensated for by more efficient HOBr-driven recycling in clouds compared to previous GEOS-Chem versions. Simulated BrO in the MBL is generally much higher in winter than in summer due to a combination of greater SSA emission and slower conversion of bromine radicals to HBr. An outstanding issue in the model is the overestimate of free-tropospheric BrO in extratropical winter–spring, possibly reflecting an overestimate of the HOBr∕HBr ratio under these conditions where the dominant HOBr source is hydrolysis of BrNO3.
