A Survey on the Oral Health Conditions according to Dental Health Behaviors of Elderly People in Community (2005)

Objectives: This study aimed to reveal the oral health conditions based on the dental health behaviors of a community-dwelling elderly. Methods: The subjects included 206 rural dwellers(100 men & 106 women) aged over 65 years old. Who received dental health check-ups in the local public health center and its branches attached to 6 respective Myons of Chunchongnamdo Province. During the 2-month period from Jan. 1st to Feb. 28th, 2005. They were examined by dentists and given self-administered questionnaires asking about their dental health behaviors and subjective symptoms of gingival bleeding. Results: The oral health conditions based on dental health behavior showed that those who have not taken dental health service a year were found to have significantly greater number of missing teeth (p=0.002), DMFT(p=0.002) and CPITN(p=0.018), and those who have not observed intra-oral conditions a week to have significantly less number of filled teeth(p=0.002) and significantly greater number of missing teeth(p=0.000) and CPITN(p=0.000) than their respective counterparts. In terms of brushing, those who brushed their teeth times/day were found to have significantly greater number of decayed teeth(p=0.000), missing teeth(p=0.000), DMFT(p=0.000) and CPITN(p=0.000) than their counterparts. In terms of time spent in brushing, those who spends below 3 minutes had significantly greater number of missing teeth(p=0.002) and DMFT(p=0.041), and significantly less number of filled teeth(p=0.036). According to the use of aid tools for cleaning teeth, the group who don't use them had significantly greater number of DMFT(p=0.041) and CPITN(p=0.018) than its counterpart. Classified by smoking habits, smoking groups had significantly greater number of decayed teeth(p=0.035) and CPITN(p=0.001) than non- smoking groups. Multiple regression analysis of the study data revealed that the significant factors influencing number of decayed teeth were number of brushing, sex and intra-oral observation (explanatory power of 14.2%). The significant factors for number of filled teeth were sex, intra-oral observation, use of aid tools, frequency of brushing, subjective health conditions and drinking of sweet beverages(explanatory power of 18.2%), those for number of missing teeth, number of brushing and age(explanatory power of 13.9%) those for DMFT, number of brushing, sex, use of dental service, age(explanatory power: 13.5%), and those for DPITN included smoking habits, use of dental service, use of aid tools (explanatory power: 10.8%). Conclusions: The study results revealed that the dental health behavior of the elderly population is in poor conditions and their consequent intra-oral health conditions are not good. To improve their oral conditions, public campaign and education will be needed to modify unhealthy dental health behaviors.
GPCR-dependent biasing of GIRK channel signaling dynamics by RGS6 in mouse sinoatrial nodal cells (2020)

How G protein-coupled receptors (GPCRs) evoke specific biological outcomes while utilizing a limited array of G proteins and effectors is poorly understood, particularly in native cell systems. Here, we examined signaling evoked by muscarinic (M<sub>2</sub>R) and adenosine (A<sub>1</sub>R) receptor activation in the mouse sinoatrial node (SAN), the cardiac pacemaker. M<sub>2</sub>R and A<sub>1</sub>R activate a shared pool of cardiac G protein-gated inwardly rectifying K<sup>+</sup> (GIRK) channels in SAN cells from adult mice, but A<sub>1</sub>R-GIRK responses are smaller and slower than M<sub>2</sub>R-GIRK responses. Recordings from mice lacking Regulator of G protein Signaling 6 (RGS6) revealed that RGS6 exerts a GPCR-dependent influence on GIRK-dependent signaling in SAN cells, suppressing M<sub>2</sub>R-GIRK coupling efficiency and kinetics and A<sub>1</sub>R-GIRK signaling amplitude. Fast kinetic bioluminescence resonance energy transfer assays in transfected HEK cells showed that RGS6 prefers Gα<sub>o</sub> over Gα<sub>i</sub> as a substrate for its catalytic activity and that M<sub>2</sub>R signals preferentially via Gα<sub>o</sub>, while A<sub>1</sub>R does not discriminate between inhibitory G protein isoforms. The impact of atrial/SAN-selective ablation of Gα<sub>o</sub> or Gα<sub>i2</sub> was consistent with these findings. Gα<sub>i2</sub> ablation had minimal impact on M<sub>2</sub>R-GIRK and A<sub>1</sub>R-GIRK signaling in SAN cells. In contrast, Gα<sub>o</sub> ablation decreased the amplitude and slowed the kinetics of M<sub>2</sub>R-GIRK responses, while enhancing the sensitivity and prolonging the deactivation rate of A<sub>1</sub>R-GIRK signaling. Collectively, our data show that differences in GPCR-G protein coupling preferences, and the Gα<sub>o</sub> substrate preference of RGS6, shape A<sub>1</sub>R- and M<sub>2</sub>R-GIRK signaling dynamics in mouse SAN cells.
Uplink Spatial Scheduling with Adaptive Transmit Beamforming in Multiuser MIMO Systems (2006)

This paper presents uplink spatial scheduling with adaptive transmit beamforming, where terminals perform system-based transmit beamforming in multiuser multi-input multi-output (MIMO) systems. In the presented spatial scheduling, the base station (BS) selects appropriate combination of terminals and their transmit beamforming among possible terminals. In the selection process, a terminal and its transmit beamforming for a signal are successively selected, considering the effect of the other predetermined signals. In performance evaluation, we show that the spatial scheduling achieves much larger system throughput than the system without spatial scheduling. We also present a basic system configuration in which the BS reports the target transmit beamforming to the selected terminal efficiently in time-division duplex (TDD) system downlink
Functional characterization of the human high‐affinity choline transporter1 (2000)

Na(+)-dependent, high-affinity choline uptake in cholinergic neurons is the rate-limiting step in acetylcholine synthesis. Here we report the molecular cloning and functional characterization of the human high-affinity choline transporter (hCHT1). The hCHT1 exhibits significant homology with known members of the Na(+)-dependent glucose transporter family, but not with members of the neurotransmitter transporter family. The human CHT1 gene is 25 kb in length with 9 exons and was assigned to chromosome II at position IIq11-12. Northern blot analysis showed that a 5.4 kb hCHT1 transcript was expressed exclusively in tissues containing cholinergic neurons. When expressed in Xenopus oocytes, the human clone induced Na(+)- and Cl(-)-dependent, high-affinity choline uptake, which was sensitive to the specific inhibitor hemicholinium-3, with a K(i) of 1.3 nM. The hCHT1-mediated choline uptake increased with increasing concentrations of choline, Na(+) and Cl(-), with EC(50) values of 2.0 microM, 76 mM, and 48 mM, and with apparent Hill coefficients of 1, 2.5 and 2.3, respectively.
Metallization of nanobiostructures: a theoretical study of copper nanowires growth in microtubules (2006)

A theoretical study of possible metallization sites within polypeptide structures is reported. The study has involved performing density functional B3LYP calculations in order to describe the affinities of various amino acids and larger peptide fragments towards copper ions. The results obtained for small amino acid systems have been used in the theoretical analysis of feasible metallization sites in large protein segments and in the whole proteins. The goal of this study was to explain the preferred inner-surface copper metallization of microtubules over outer-surface metallization. The inner-surface metallization is a new process that yields copper wires of 15 nm in diameter and may be used for fabrication of molecular interconnects at the nano-device level.
Can EPS Development be Avoided with Early Interventions? The Potential Role of Tamoxifen—A Single-Center Study (2014)

Being a serious, life-threatening complication of PD, EPS requires high suspicion to allow for prompt diagnosis and treatment. Early detection of EPS-prone states and delivery of appropriate intervention might prevent EPS development. Tamoxifen seems to be a key strategy in prevention, but caution should be used in interpreting our results. Additional randomized controlled studies are needed.

Energy-Coupling of the Transport System of Escherichia coli Dependent on Maltose-Binding Protein (1977)

1 Accumulation of substrate via the maltose transport system of Escherichia coli is incompletely inhibited by uncouplers of oxidative phosphorylation. The extent of this inhibition is reduced upon introduction of a mutation in the Mg2+ Ca2+-dependent ATPase. This suggests the lack of importance of the proton motive force for accumulation of substrate. 2 Starved cells of the ATPase mutant show a reduced rate of maltose uptake. This low rate was strongly stimulated by the glycolytic carbon source D-fructose but not by oxidisable energy sources such as d-lactate or ascorbate plus phenazine methosulphate. These findings are also in agreement with the lack of importance of the proton motive force in maltose accumulation. 3 Incubation of wild-type as well as ATPase-less cells with high concentrations of arsenate, that is known to deplete the intracellular level of ATP in E. coli, did not significantly inhibit the uptake of maltose. This suggests that the level of intracellular ATP is not directly the energy source for maltose uptake. 4 The exit of maltose, in both the wild-type and the ATPase-less strains, is inhibited by uncouplers of oxidative phosphorylation. Azide, dinitrophenol, and carbonyl cyanide chlorophenyl-hydrazone inhibited the downhill exit of maltose and also the exchange of maltose; arsenate did not. This suggests a requirement for the proton motive force in transport of maltose in the outward direction, and contrasts from the properties of the entry reaction. These results are consistent with the view that entry and exit of maltose are mediated via different carriers and energized by different modes.
Point-in-time loss-given default rates and exposures at default models for IFRS 9/CECL and stress testing (2016)

In contrast with Basel II rules, which call for the use of through-the-cycle (TTC) probabilities of default (PDs) and downturn (DT) loss-given default rates (LGDs) and exposures at default (EADs), the regulatory stress tests and the new IFRS 9 and proposed Current Expected Credit Loss (CECL) accounting standards require institutions to use point-in-time (PIT) projections of PDs, LGDs and EADs. By accounting for the current state of the credit cycle, PIT measures track closely the variations in default and loss rates over time. In past publications the authors have described the derivation of industry-region credit-cycle indices (CCIs) and the use of those indices in converting legacy wholesale credit PD models, which typically understate cyclical variations, into fully PIT ones. This paper extends that framework to cover estimation of PIT LGDs and EADs for wholesale exposures. The authors offer options for the formulation of such models and discuss their experience in building PIT LGD and EAD models, and show that, by accounting for the probabilistic evolution over time in industry-region CCIs, one can derive joint, PD, LGD and EAD scenarios for use in the regulatory stress tests or in estimating the term structures of expected credit losses (ECLs) as needed for IFRS 9/CECL.
Minimally invasive total knee replacement using a mini-mid vastus incision technique and results. (2004)

This study was performed to determine whether differences existed between primary knee replacement performed through a standard medial parapatellar approach, and those performed through a minimally invasive mini-mid vastus approach. It was a prospective study compared with a retrospective evaluation of a matched cohort. In this study, the Genesis(tm) II and its MIS instrumentation were used. Patients with the mini-mid vastus MIS incision (MMV MIS) required less pain medication post-operatively, regained their flexion more rapidly, and attained their functional milestones at an earlier point than those with the traditional median parapatellar long incision. Despite the smaller incision, component placement was radiographically excellent in all cases. Optimal performance of the surgery required the use of special instrumentation, modified so as to be used in smaller incisions.

A pipeline for identification of bird and frog species in tropical soundscape recordings using a convolutional neural network (2020)

Automated acoustic recorders can collect long-term soundscape data containing species-specific signals in remote environments. Ecologists have increasingly used them for studying diverse fauna around the globe. Deep learning methods have gained recent attention for automating the process of species identification in soundscape recordings. We present an end-to-end pipeline for training a convolutional neural network (CNN) for multi-species multi-label classification of soundscape recordings, starting from raw, unlabeled audio. Training data for species-specific signals are collected using a semi-automated procedure consisting of an efficient template-based signal detection algorithm and a graphical user interface for rapid detection validation. A CNN is then trained based on mel-spectrograms of sound to predict the set of species present in a recording. Transfer learning of a pre-trained model is employed to reduce the necessary training data and time. Furthermore, we define a loss function that allows for using true and false template-based detections to train a multi-class multi-label audio classifier. This approach leverages relevant absence (negative) information in training, and reduces the effort in creating multi-label training data by allowing weak labels. We evaluated the pipeline using a set of soundscape recordings collected across 749 sites in Puerto Rico. A CNN model was trained to identify 24 regional species of birds and frogs. The semi-automated training data collection process greatly reduced the manual effort required for training. The model was evaluated on an excluded set of 1000 randomly sampled 1-min soundscapes from 17 sites in the El Yunque National Forest. The test recordings contained an average of ~3 present target species per recording, and a maximum of 8. The test set also showed a large class imbalance with most species being present in less than 5% of recordings, and others present in >25%. The model achieved a mean-average-precision of 0.893 across the 24 species. Across all predictions, the total average-precision was 0.975.

A shorted cross bowtie patch antenna with a cross dipole for circular polarization (2007)

A novel circular-polarized antenna composed of bowtie patches, cross dipole and a power combiner is presented. Two air microstrip lines are utilized to feed the bowtie patches orthogonally. A 90-degree phase shift Wilkinson power divider is placed underneath the ground and connected to the feeds to generate circular polarization. The antenna attains an impedance bandwidth of 40.2% for return loss better than -15 dB and 3-dB axial ratio bandwidth of 29% (from 1.62 to 2.17 GHz). Very Stable and symmetric radiation patterns with low cross polarization level have been obtained over the operating frequency range. The 3-dB axial ratio beamwidth is about 90deg and the gain of the antenna is about 6.3 dBi with small variation.
Influence of ovarian surface epithelium and rete ovarii on follicle formation. (1977)

Early follicle development has been studied in mouse ovaries grafted to immunologically incompetent hosts. Early follicular formation and growth is apparently dependent on the presence of the rete ovarii: the surface epithelium does not seem to play a decisive role. This was shown in transplantation studies of fetal gonads which had been divided into parts with and without the rete ovarii. None of the rete-depleted ovaries exhibited normal follicular differentiation regardless of the presence or absence of the surface epithelium, whereas follicles developed normally in all the implants containing the rete system.
Unsupervised domain adaptation for lip reading based on cross-modal knowledge distillation (2021)

Abstract We present an unsupervised domain adaptation (UDA) method for a lip-reading model that is an image-based speech recognition model. Most of conventional UDA methods cannot be applied when the adaptation data consists of an unknown class, such as out-of-vocabulary words. In this paper, we propose a cross-modal knowledge distillation (KD)-based domain adaptation method, where we use the intermediate layer output in the audio-based speech recognition model as a teacher for the unlabeled adaptation data. Because the audio signal contains more information for recognizing speech than lip images, the knowledge of the audio-based model can be used as a powerful teacher in cases where the unlabeled adaptation data consists of audio-visual parallel data. In addition, because the proposed intermediate-layer-based KD can express the teacher as the sub-class (sub-word)-level representation, this method allows us to use the data of unknown classes for the adaptation. Through experiments on an image-based word recognition task, we demonstrate that the proposed approach can not only improve the UDA performance but can also use the unknown-class adaptation data.
New Designs Of Holographic Helmet Displays (1988)

When used with monochromatic light, holographic helmet displays have distinct advantages when compared to conventional helmet displays. Unfortunately, the holographic elements needed for such displays must perform over a large field of view, and generally suffer from severe aberrations. To overcome these aberrations it is necessary to holographically record complex wavefronts, which can not be obtained with standard optical components. A recursive design technique for obtaining the desired complex wavefronts from relatively simple intermediate holograms is developed. It is based on changing the geometries and the wavelength between the recording and readout of the intermediate holograms. The design technique is illustrated for a single holographic helmet display element having resolution of less then one miliradian over a field of view of 16°x16°.
Stability of Per- and Polyfluoroalkyl Substances in Solvents Relevant to Environmental and Toxicological Analysis (2021)

Per- and polyfluoroalkyl substances (PFASs) are widely used anthropogenic chemicals. For environmental and toxicological analysis, it is important to understand the stability of PFASs, including novel per- and polyfluoroalkyl ether acids (PFEAs), in commonly used solvents. In this study, we investigated the effects of PFAS characteristics, solvent type, water-to-organic solvent ratio, and temperature on the stability of 21 PFASs including 18 PFEAs. None of the studied PFASs showed measurable degradation in deionized water, methanol, or isopropyl alcohol over 30 days; however, nine PFEAs degraded in the polar aprotic solvents acetonitrile, acetone, and dimethyl sulfoxide (DMSO). PFEA degradation followed first-order kinetics, and first-order rate constants increased with increasing temperature and with decreasing water-to-organic solvent ratio. Monoethers with a carboxylic acid functional group adjacent to a tertiary carbon (>CF-COOH) degraded more rapidly than multiethers in which the carboxylic acid moiety was adjacent to repeating -CF<sub>2</sub>O- groups. In contrast, monoethers with a carboxylic acid moiety adjacent to a secondary carbon (-CF<sub>2</sub>-COOH) were stable in all tested solvents. Using high-resolution mass spectrometry, we determined that PFEAs with a >CF-COOH group were stoichiometrically decarboxylated in aprotic solvents and formed products with a >CFH group; e.g., hexafluoropropylene oxide-dimer acid (HFPO-DA or GenX), HFPO-trimer acid, and HFPO-tetramer acid were stoichiometrically converted to Fluoroethers E-1, E-2, and E-3, respectively. PFEA degradation results highlight the importance of solvent choice when preparing dosing solutions and performing extractions for environmental and toxicological assessments of PFEAs.
