The Relationship between Body Mass Index and Smoking Cessation Plans in Korean Adults (2017)

Normal weight subjects tended to have a greater number of smoking cessation plans than the other three weight groups, but the difference was not statistically significant. In the clinic, it is necessary to consider not only BMI but also other factors associated with a smoking cessation plans.
Near-infrared optical gain and stimulated emission in organic-compound-doped polymer waveguides (2004)

We have successfully incorporated a near-infrared-emitting compound, 2-(6-(4-Dimethylaminophenyl)-2,4-neopentylene-1,3,5-hexatrienyl)-3-methyl-benzothiazolium Perchlorat, into poly(1-vinyl-2-pyrrolidone)-base planar waveguides. The variable-stripe-length method is employed to deduce the net gain coefficient of the waveguides, 1 cm in length, doped with 0.5 wt.% of the compound. The gain spectroscopy has revealed a moderate net modal gain of 2.6 cm<sup>-1 </sup>at 820 nm for the pump fluence of 22.6 &mu;J/cm<sup>2</sup> (3.8 kW/cm<sup>2</sup>). The waveguides have exhibited lasing at 820 nm when they are transversely photoexcited at 532 nm with a nanosecond Nd: YAG laser. The Fresnel reflection at the polymer-air interfaces acts as a low-finesse Fabry-Perot cavity. The threshold for lasing has been found to be 24.5 &mu;J/cm<sup>2</sup> (4.1 kW/cm<sup>2</sup>).

A router architecture for real-time point-to-point networks (1996)

Parallel machines have the potential to satisfy the large computational demands of emerging real-time applications. These applications require a predictable communication network, where time-constrained traffic requires bounds on latency or throughput while good average performance suffices for best-effort packets. This paper presents a router architecture that tailors low-level routing, switching, arbitration and flow-control policies to the conflicting demands of each traffic class. The router implements deadline-based scheduling, with packet switching and table-driven multicast routing, to bound end-to-end delay for time-constrained traffic, while allowing best-effort traffic to capitalize on the low-latency routing and switching schemes common in modern parallel machines. To limit the cost of servicing time-constrained traffic, the router shares packet buffers and link-scheduling logic between the multiple output ports. Verilog simulations demonstrate that the design meets the performance goals of both traffic classes in a single-chip solution.
Epidemic Models for COVID-19 during the First Wave from February to May 2020: a Methodological Review (2021)

Abstract We review epidemiological models for the propagation of the COVID-19 pandemic during the early months of the outbreak: from February to May 2020. The aim is to propose a methodological review that highlights the following characteristics: ( i ) the epidemic propagation models, ( ii ) the modeling of intervention strategies, ( iii ) the models and estimation procedures of the epidemic parameters and ( iv ) the characteristics of the data used. We finally selected 80 articles from open access databases based on criteria such as the theoretical background, the reproducibility, the incorporation of interventions strategies, etc . It mainly resulted to phenomenological, compartmental and individual-level models. A digital companion including an online sheet, a Kibana interface and a markdown document is proposed. Finally, this work provides an opportunity to witness how the scientific community reacted to this unique situation.
Industrially Fabricated Bifacial Si Solar Cells with n+-p-p+ Structure (2013)

Photovoltaic and recombination properties of bifacial solar cells are analyzed. The cells were fabricated in a pilot production line using 6" pseudosquare wafers of 3 to 6 .cm single crystalline Cz Si. Their front efficiency is in the range 18.1 – 18.8 % with back to front short circuit current ratio 74 - 79 %. The design is characterized by high bulk minority carrier lifetime 0.2 – 1 ms, not degraded during the fabrication process, when good starting wafers were used. Effective back surface recombination is in the range 55 - 95 cm/s. Light trapping due to high back internal reflection contributes to current improvement compared to a regular mono facial cell with Al alloyed back. Equivalent efficiency as a quality criteria of a bifacial solar cell is proposed. Routine adjustment of fabrication process promise the increase of average front efficiency above 19 % and equivalent efficiency above 24 %.
Stable diplatinum complexes with functional thiolato bridges from dialkylation of [Pt2(µ-S)2(P–P)2] [P–P = 2 × PPh3, Ph2P(CH2)3PPh2] (2007)

The normally robust monoalkylated complexes [Pt(2)(mu-S)(mu-SR)(PPh(3))(4)](+) can be activated towards further alkylation. Dialkylated complexes [Pt(2)(mu-SR)(2)(P-P)(2)](2+) (P-P=2 x PPh(3), Ph(2)P(CH(2))(3)PPh(2)) can be stabilized and isolated by the use of electron-rich and aromatic halogenated substituents R [e.g. 3-(2-bromoethyl)indole and 2-bromo-4'-phenylacetophenone] and 1,3-bis(diphenylphosphino)propane [Ph(2)P(CH(2))(3)PPh(2) or dppp] which enhances the nucleophilicity of the {Pt(2)(mu-S)(2)} core. This strategy led to the activation of [Pt(2)(mu-S)(mu-SR)(PPh(3))(4)](+) towards R-X as well as isolation and crystallographic elucidation of [Pt(2)(mu-SC(10)H(10)N)(2)(PPh(3))(4)](PF(6))(2) (2a), [Pt(2)(mu-SCH(2)C(O)C(6)H(4)C(6)H(5))(2)(PPh(3))(4)](PF(6))(2) (2b), and a range of functionalized-thiolato bridged complexes such as [Pt(2)(mu-SR)(2)(dppp)(2)](PF(6))(2) [R= -CH(2)C(6)H(5) (8a), -CH(2)CHCH(2) (8b) and -CH(2)CN (8c)]. The stepwise alkylation process is conveniently monitored by Electrospray Ionisation Mass Spectrometry, allowing for a direct qualitative comparison of the nucleophilicity of [Pt(2)(mu-S)(2)(P-P)(2)], thereby guiding the bench-top synthesis of some products observed spectroscopically.
TRH mobilizes membrane calcium in thyrotropic cells as monitored by chlortetracycline (1982)

Chlortetracycline (CTC), a probe of membrane-bound divalent cations, was used to study the action of thyrotropin-releasing hormone (TRH) in mouse pituitary thyrotropic tumor (TtT) cells in culture. Cellular fluorescence of CTC was caused by both Ca2+- and Mg2+-CTC complexes and was influenced by the concentration of these cations in the incubation medium. TRH, but not other peptides, caused a rapid, transient, and concentration-dependent decrease in the CTC fluorescence intensity; half-maximal effect occurred with 10--30 nM TRH. The decrement in fluorescence intensity caused by TRH was not due to enhanced loss of CTC from the cells. The decrease in fluorescence elicited by TRH was specific for Ca2+-CTC complexes because preincubation of the cells with 1 mM EGTA or 1 mM EDTA plus 2.05 mM Mg2+ abolished the response, whereas preincubation with 1 mM EDTA plus 2.05 mM Ca2+ permitted the usual TRH response. Antimycin A and carbonyl cyanide m-chlorophenylhydrazone decreased cellular ATP content to 37 +/- 1 and 32 +/- 1% of control, respectively, and abolished the TRH-induced decrease in CTC fluorescence. We conclude that TRH displaced Ca2+ from an energy-dependent, membrane-bound pool(s) within TtT cells and that this may be one mechanism by which the concentration of intracellular free Ca2+ is raised so that is couples stimulation by TRH to TSH secretion.
Structural defects and chemical interaction of implanted ions with substrate structure in amorphous<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">SiO</mml:mi></mml:mrow><mml:mrow><mml:mn>2</mml:mn></mml:mrow></mml:msub></mml:mrow></mml:math> (1993)

Structural defects in ${\mathrm{SiO}}_{2}$ glasses implanted with ${\mathrm{Li}}^{+}$, ${\mathrm{N}}^{+}$, ${\mathrm{O}}^{+}$, ${\mathrm{F}}^{+}$, ${\mathrm{Si}}^{+}$, and ${\mathrm{P}}^{+}$ ions were examined by vacuum-ultraviolet-absorption and electron-paramagnetic-resonance spectroscopies as well as thermal-gas-release analysis. The chemical interaction of implanted ions with substrate structure was considered on the basis of the obtained results. It is found that the type of predominant defects is controlled by the electronegative nature of implants. Silicon-silicon homobonds, which are oxygen-vacancy-type defects, are produced by electropositive implants (i.e., Li, P, and Si) at concentrations comparable to those of the implants. On the other hand, in the case of electronegative implants (F and O) ${\mathrm{O}}_{2}$ molecules and peroxy radicals (POR), both of which may be regarded as oxygen-interstitial-type defects, are the major defects and the total concentrations of these two defects are comparable to implant concentrations. These results indicate that chemical interaction of implanted ions with ${\mathrm{SiO}}_{2}$ is primarily controlled by the electronegative nature of implants. Electropositive implants (M) react chemically with oxygen atoms in the substrate structure to form M-O bonds, leaving Si-Si bonds. Electronegative implants (A) react chemically with silicon atoms to form Si-A bonds and oxygen atoms recoiled with implants combine with each other to form ${\mathrm{O}}_{2}$ molecules or react with the silica-network structure to form POR's. Concentrations of these predominant defects relative to implants can be used quantitatively to describe the strength of chemical interactions. When the chemical interaction is strong, both concentrations are comparable. On the other hand, when the chemical interaction is weak, concentrations of these defects are much smaller than those of implants because the major fraction of implants occur in a neutral state without forming chemical bonds with constituents of the substrate. Nitrogen is an example of this category and the major fraction of implanted nitrogen atoms are present as ${\mathrm{N}}_{2}$ molecules.
A connective framework to minimize the anxiety of collaborative Cyber-Physical System (2023)

The role of Cyber-Physical systems (CPS) is well recognized in the context of Industry 4.0, which consists of human operators working with machines/robots. The interactions among them can be quite demanding in terms of cognitive resources. Existing systems do not yet consider the psychological aspects of safety in the domain. This lack can lead to hazardous situations, thus compromising the performance of the working system. This work proposes a connective decision-making framework for a flexible CPS, which can quickly respond to dynamic changes and be resilient to emergent hazards. First, Anxiety is defined and categorized for expected/unforeseen situations that a CPS could encounter through historical data using the Ishikawa method. Second, visual cues are used to gather the CPS’s current state (such as human pose and object identification). Third, a mathematical model is developed using Mixed-integer programming (MIP) to allocate optimal resources, to tackle high-impact situations generating Anxiety. Finally, the logic is designed for an effective counter-mechanism to mitigate Anxiety. The proposed method was tested on a realistic industrial scenario incorporating a collaborative CPS. The results demonstrated that the proposed method improves the decision-making of a CPS facing a complex scenario, ensures physical safety, and effectively enhances the human-machine team’s productivity.
Pigmentation and lysosomal phenotypes in mice doubly homozygous for both light-ear and pale-ear mutant alleles (1984)

We have developed a new strain of mice homozygous for mutant alleles at both the light-ear locus on chromosome 5 and the pale-ear locus on chromosome 19. The pigmentation pattern of the double mutants, designated light-pale, is indistinguishable from the parental type. Elevated concentrations of lysosomal enzymes observed in certain tissues of the light-ear and pale-ear singly homozygous mice also are present in the double mutants, and are quantitatively indistinguishable from either parent. Although both mutations have pleiotropic effects on organelles in several tissues, neither locus influences the secretion of pancreatic zymogen granules. The close similarity in phenotypes of light ear, pale ear, and light-pale mice suggest that the le and ep loci encode different subunits of a multimeric protein, and that mutations affecting either subunit result in comparable losses of function.
Spectroscopic Investigation of AgOx Films for Super Resolution Near Field Structure Application. (2001)

In this work thin silver oxide layers (AgOx) were prepared by reactive sputtering of a silver target in oxygen containing atmosphere. We report a gradual composition change of the deposited layers with increasing oxygen concentration from Ag over Ag2O to AgO and furthermore that dispersed silver clusters are present even up to high O2 concentrations. Raman- along with IR-spectroscopy and ellipsometric measurements reveal specified compounds at defined oxygen concentrations. Optical transmission and reflection measurements as a function of temperature show that these compounds exhibit phase transitions (i.e. AgO decomposes to Ag2O and finally to Ag), connected to considerable refractive index changes. This work was done with respect to super-Resolution Near-Field Structures where these effects are exploited to realize ultra high optical data storage in combination with magneto-optical and phase change recording materials.

Intraoral oblique sagittal splitting osteotomy for mandibular prognathism with or without anterior openbite. 2. Longitudinal observation with lateral cephalograms. (1986)

Thirty-four cases of mandibular prognathism treated with intraoral oblique sagittal splitting osteotomy were evaluated retrospectively by cephalometric analysis of skeletal changes of the mandible during at least 6 months after surgery. The subjects were 17 cases of prognathism and 17 cases of prognathism with anterior openbite.In those cases of prognathism alone, the distal segment (represented by the point labelled Gn) and the proximal segment (represented by the point Go) were surgically reduced posteriorly parallel to the SN line. In those cases with openbite, the distal segment was surgically mored postero-superiorly and the proximal segment postero-inferiorly.During intermaxillary fixation, the distal segment remained stable, but the proximal segment returned to the almost preoperative position in both groups of subjects. Until 6 months after releasing the fixation, the distal segment moved antero-superiorly and the proximal segmentinferiorly in the group with prognathism alone. In the other group, both segment remained stable.After 6 months, both segments remained stable in both groups.However, the total degree of mandibular regression was so slight that none of cases relapsed to edge-to-edge or Class III malocclusion during the follow-up period.
Laser Induced Chemical Vapour Deposition Of Platinum Spots On Glass (1989)

Laser induced pyrolytic deposition of platinum spots on glass is studied for different laser powers, beam diameters and irradiation time. Laser powers up to 500 mW give deposition rates of typically 0.5 &mu;m/s. Temperature calculations as a function of the time allows study of the process kinetics according to the thickness and diameter of the spots. Resistivity measurements of platinum lines give comparable values to those of bulk material.
Direct Model Predictive Control: A Review of Strategies That Achieve Long Prediction Intervals for Power Electronics (2014)

Direct model predictive control (MPC) strategies that achieve long prediction horizons with a modest computational complexity are reviewed in this article, focusing on power electronics applications. In many MPC problems, a long prediction horizon is required to ensure an adequate closed-loop performance in steady state and to avoid stability issues. However, the computational effort of solving the optimization problem underlying MPC problems with long prediction horizons is often very great, making the implementation of such schemes in real time a difficult and challenging task. To overcome this difficulty, three established methodologies are surveyed that yield long prediction horizons with a modest computational burden. Case studies are investigated to substantiate the merits of these schemes. More specifically, for dc?dc boost converters, a move blocking strategy is reviewed, and for ac medium-voltage (MV) drives, both an extrapolation and an event-based horizon strategy are examined.
Three-Dimensional Imaging and Scattering Mechanism Estimation Over Urban Scenes Using Dual-Baseline Polarimetric InSAR Observations at L-Band (2011)

This paper introduces new polarimetric algorithms for generating 3-D images and estimating scattering mechanisms from polarimetric multibaseline (MB) interferometric synthetic aperture radar (SAR) measurements. First, an MB interferometric SAR signal model is generalized to the fully polarimetric configuration, establishing the notion of polarimetric reflectivity. Subsequently, polarimetric beamforming, Capon, and MUSIC methods that determine optimal polarization combinations for height estimation are developed. These new techniques allow for extracting the height of reflectors, the associated scattering mechanisms, and the polarimetric (pseudo)reflectivities. By means of polarimetric dual-baseline interferometric SAR observations of an urban environment, the performance of the conceived algorithms is examined in detail. Producing 3-D images of a building layover, the quality of the approaches is compared in terms of refined resolution and lowered side lobes. Furthermore, the scattering processes occurring in urban scenes are investigated thoroughly by analyzing the optimal reflection types. The algorithms are validated using dual-baseline polarimetric SAR interferometric data at L-band acquired by German Aerospace Center's experimental SAR system over Dresden city.
Development of a Six-Stage Culture System for Simulating the Gastrointestinal Microbiota of Weaned Infants (2001)

The development of a six-stage culture system simulating the microbial community present in the intestine of weaned infants is described. Plate counts of selected fecal indicator-organisms revealed high concentrations in the culture liquid of the simulator and these data paralleled those in infant feces. The metabolic patterns of the microbiota present in the model and the infant feces, compared by means of BIOLOG, revealed similar carbon utilization profiles. A genetic ? ngerprinting by means of Denaturing Gradient Gel Electrophoresis generated a more complex banding pattern in the culture system than in infant feces. The three vessels representing the colon showed similar DGGE patterns, indicating a high stability of the dominant microbial species. Yet, high variability in terms of the dominant bacteria was observed in infant stools. The fermentative capacity of the in vitro system, characterized by the concentration of volatile fatty acids and ammonium, was in accordance with the in vivo data. The enhanced production of propionate in vitro is probably due to the high concentration of fermentable sugars in the culture medium and hence, a high fermentation rate. The elevated concentration of propionate, as well as valerate and caproate in vitro suggests conditions favoring Megasphaera sp. fermentation. The data concerning microbial diversity and activity warrants further exploration of the in vitro model as a tool for studying the impact of newly developed infant formulas, functional foods and pharmaceuticals on the gastrointestinal microbiota of infants. Keywords: intestinal microbiota, gut fermentation, infant, culture system.
Comparison of variable and conventional ventilation in a sheep saline lavage lung injury model* (2006)

The application of VV in a large animal model of lung injury results in improved gas exchange and superior lung mechanics in comparison with CV that can be explained at least partially by the long-lasting effects of the recruitments occurring during VV.
Optimization of Polymer-ECM Composite Scaffolds for Tissue Engineering: Effect of Cells and Culture Conditions on Polymeric Nanofiber Mats (2017)

The design of composite tissue scaffolds containing an extracellular matrix (ECM) and synthetic polymer fibers is a new approach to create bioactive scaffolds that can enhance cell function. Currently, studies investigating the effects of ECM-deposition and decellularization on polymer degradation are still lacking, as are data on optimizing the stability of the ECM-containing composite scaffolds during prolonged cell culture. In this study, we develop fibrous scaffolds using three polymer compositions, representing slow (E0000), medium (E0500), and fast (E1000) degrading materials, to investigate the stability, degradation, and mechanics of the scaffolds during ECM deposition and decellularization, and during the complete cellularization-decell-recell cycle. We report data on percent molecular weight (% Mw) retention of polymeric fiber mats, changes in scaffold stiffness, ECM deposition, and the presence of fibronectin after decellularization. We concluded that the fast degrading E1000 (Mw retention ≤ 50% after 28 days) was not sufficiently stable to allow scaffold handling after 28 days in culture, while the slow degradation of E0000 (Mw retention ≥ 80% in 28 days) did not allow deposited ECM to replace the polymer support. The scaffolds made from medium degrading E0500 (Mw retention about 60% at 28 days) allowed the gradual replacement of the polymer network with cell-derived ECM while maintaining the polymer network support. Thus, polymers with an intermediate rate of degradation, maintaining good scaffold handling properties after 28 days in culture, seem best suited for creating ECM-polymer composite scaffolds.
