Scientific Analysis of Wooden Lacquerware from No.1 Wooden Coffin Burial in Yangji-ri Gyeongsangbuk-do, Republic of Korea (2022)

In this paper, the four lacquerware excavated from the burial floor fit of the Yangji-ri No. 1 wooden coffin was analyzed to confirm the manufacturing techniques and materials. The lacquerware was made of wood and metal, therefore, and we analyzed the lacquerware based on the its constituent materials characteristics. We found that the coins decorating the surface of the bronze halberd were Wu Zhu Chinese coins and that the bronze spearhead was long and narrow by X-ray based on non-destructive investigations. Also, Wu Zhu Chinese coins and bronze spearhead are consists of leaded bronze and were produced by casting.The lacquer layer of the surface of four lacquerware was composed of common lacquer ingredients and applied directly to the wood without a base lacquer layer. This study provides basic data for studies on ancient lacquer techniques.
Single Molecule Experiments Challenge the Strict Wave-Particle Dualism of Light (2010)

Single molecule techniques improve our understanding of the photon and light. If the single photon double slit experiment is performed at the "single photon limit" of a multi-atom light source, faint light pulses with more than one photon hamper the interpretation. Single molecules, quantum dots or defect centres in crystals should be used as light source. "Single photon detectors" do not meet their promise-only "photon number resolving single photon detectors" do so. Particularly, the accumulation time argument, the only safe basis for the postulate of a strictly particle like photon, has so far not yet been verified.
Applications of 17O NMR Spectroscopy to Structural Problems in Organic Chemistry: Torsion Angle Relationships (2020)

Until recently, the application of O nuclear magnetic resonance (NMR) spectroscopy to organic chemistry as a method for structure and conformation elucidation as well as a probe for assessing electronic distribution had been under-utilized significantly. This chapter deals with one category: systems in which steric interactions are characterized by rotation of functional groups around single bonds to relieve van der Waals interactions. It focuses on rigid systems in which steric interactions are partially accommodated by bond angle and bond length distortions. It is clear then that torsion angle relationships are important in these systems as well. It is clear from the studies reported to date that O NMR spectroscopy is an extremely sensitive and valuable method for assessing solution phase geometries for molecules containing any one of a number of different functional groups.
New MTCMOS Flip-Flops with Simple Control Circuitry and Low Leakage Data Retention Capability (2007)

The previous MTCMOS sequential circuit techniques with data preserving sleep modes require either a distributed sleep switch circuit structure with a significant area overhead or a complex peripheral control circuitry for preserving and restoring the data. Two new master-slave MTCMOS flip-flops with centralized sleep switches providing a low leakage and low overhead sleep mode with data retention capability are presented in this paper. A quasi-SRAM structure is combined with the slave latch of the proposed flip-flops. The already existing sleep signal of the MTCMOS circuitry is also used for controlling the data retention and restoration operations, thereby eliminating the need for any extra control signals with the new flip-flops. Furthermore, the leakage power consumption with the proposed techniques is reduced by up to 42.5% as compared to the previously published MTCMOS circuits.
Look Across Elapse: Disentangled Representation Learning and Photorealistic Cross-Age Face Synthesis for Age-Invariant Face Recognition (2018)

Despite the remarkable progress in face recognition related technologies, reliably recognizing faces across ages still remains a big challenge. The appearance of a human face changes substantially over time, resulting in significant intra-class variations. As opposed to current techniques for age-invariant face recognition, which either directly extract age-invariant features for recognition, or first synthesize a face that matches target age before feature extraction, we argue that it is more desirable to perform both tasks jointly so that they can leverage each other. To this end, we propose a deep Age-Invariant Model (AIM) for face recognition in the wild with three distinct novelties. First, AIM presents a novel unified deep architecture jointly performing cross-age face synthesis and recognition in a mutual boosting way. Second, AIM achieves continuous face rejuvenation/aging with remarkable photorealistic and identity-preserving properties, avoiding the requirement of paired data and the true age of testing samples. Third, we develop effective and novel training strategies for end-to-end learning the whole deep architecture, which generates powerful age-invariant face representations explicitly disentangled from the age variation. Moreover, we propose a new large-scale Cross-Age Face Recognition (CAFR) benchmark dataset to facilitate existing efforts and push the frontiers of age-invariant face recognition research. Extensive experiments on both our CAFR and several other cross-age datasets (MORPH, CACD and FG-NET) demonstrate the superiority of the proposed AIM model over the state-of-the-arts. Benchmarking our model on one of the most popular unconstrained face recognition datasets IJB-C additionally verifies the promising generalizability of AIM in recognizing faces in the wild.
High Electrical Conductivity in Ni<sub>3</sub>(2,3,6,7,10,11-hexaiminotriphenylene)<sub>2</sub>, a Semiconducting Metal–Organic Graphene Analogue (2014)

Reaction of 2,3,6,7,10,11-hexaaminotriphenylene with Ni(2+) in aqueous NH3 solution under aerobic conditions produces Ni3(HITP)2 (HITP = 2,3,6,7,10,11-hexaiminotriphenylene), a new two-dimensional metal-organic framework (MOF). The new material can be isolated as a highly conductive black powder or dark blue-violet films. Two-probe and van der Pauw electrical measurements reveal bulk (pellet) and surface (film) conductivity values of 2 and 40 S·cm(-1), respectively, both records for MOFs and among the best for any coordination polymer.
Sociodemographic and Genetic Influences on Dietary Patterns and Their Influence on Health Outcomes in the Atlanta Center for Health Discovery and Well Being Cohort (2020)

Diet influences, and is influenced by, a wide range of socioeconomic, cultural, geographic, and genetic variables. Here we survey a matrix of such interactions as well as their connection to a variety of health outcomes, in a cohort of 689 diverse adults employed at Emory University and enrolled in the Center for Health Discovery and Well-Being (CHDWB) study. Principal component analysis (PCA) of the Block Food Frequency Questionnaire revealed seven PC cumulatively explaining 25.8% and each individually at least 2% of the proportional consumption of 110 food items. PC1 is strongly correlated with the Healthy Eating Index-2015 measure, and accordingly healthier scores associate with multiple measures of physical and mental health. It, as well as PC2 (likely a measure of food expense) and PC3 (carbohydrate versus protein consumption) show significant geographic structure across the Atlanta metropolitan area, correlating with race and ethnicity, income level, age and sex. Notably, a polygenic score for body mass index (BMI) consisting of 281 SNPs explains 2.8% of the variance in PC5, which is as strong as its association with BMI itself. PC5 appears to differentiate participants with respect to conscious eating behavior related to the choice of diet or comfort foods. Our analysis adds to the growing literature on factor analysis of socio-demographic influences on nutrition and health.
Simultaneous Study of the Recruitment of Monocyte Subpopulations Under Flow In Vitro (2018)

The recruitment of monocytes from the blood to targeted peripheral tissues is critical to the inflammatory process during tissue injury, tumor development and autoimmune diseases. This is facilitated through a process of capture from free flow onto the luminal surface of activated endothelial cells, followed by their adhesion and transendothelial migration (transmigration) into the underlying affected tissue. However, the mechanisms that support the preferential and context-dependent recruitment of monocyte subpopulations are still not fully understood. Therefore, we have developed a method that allows the recruitment of different monocyte subpopulations to be simultaneously visualized and measured under flow. This method, based on time-lapse confocal imaging, allows for the unambiguous distinction between adherent and transmigrated monocytes. Here, we describe how this method can be used to simultaneously study the recruitment cascade of pro-angiogenic and non-angiogenic monocytes in vitro. Furthermore, this method can be extended to study the different steps of recruitment of up to three monocyte populations.
Frequency-Based Patrolling with Heterogeneous Agents and Limited Communication (2014)

This paper investigates multi-agent frequencybased patrolling of intersecting, circle graphs under conditions where graph nodes have non-uniform visitation requirements and agents have limited ability to communicate. The task is modeled as a partially observable Markov decision process, and a reinforcement learning solution is developed. Each agent generates its own policy from Markov chains, and policies are exchanged only when agents occupy the same or adjacent nodes. This constraint on policy exchange models sparse communication conditions over large, unstructured environments. Empirical results provide perspectives on convergence properties, agent cooperation, and generalization of learned patrolling policies to new instances of the task. The emergent behavior indicates learned coordination strategies between heterogeneous agents for patrolling large, unstructured regions as well as the ability to generalize to dynamic variation in node visitation requirements.

Development and characterization of EIS structures based on SiO<sub>2</sub> micropillars and pores before and after their functionalization with phosphonate films (2011)

Abstract In this work electrolyte–insulator–semiconductor (EIS) structures based on lithographically fabricated Si–SiO 2 micropillars and pores are studied. The samples are characterized by means of impedance spectroscopy (IS) and they are compared to samples with a planar SiO 2 layer on a Si substrate in order to determine whether the increase in active surface is directly related to an increase in sensitivity of the device. Our initial results confirm this question in the case of the pillar samples but not for the pore ones, most likely due to some fabrication issues that must be improved. Afterwards the SiO 2 surface is functionalized with posphonates and the influence of the modification is studied using IS. Also, the stability and limits of applicability of the functionalized devices is studied. Analysis with X‐ray photoelectron spectroscopy (XPS) is used to show that the deposition of phosphonates was successful.
Voclosporin Food Effect and Single Oral Ascending Dose Pharmacokinetic and Pharmacodynamic Studies in Healthy Human Subjects (2013)

Voclosporin (VCS) is a novel calcineurin (CN) inhibitor intended for prevention of organ graft rejection and treatment of lupus nephritis. These studies evaluated the single ascending dose pharmacokinetics (PK) and pharmacodynamics (PD, CN activity) of VCS and the effect of food. VCS was administered orally in single doses of 0.25 through 4.5 mg/kg in 62 subjects in the single ascending dose study and as a single oral 1.5 mg/kg dose to 18 subjects after fasting, consumption of a low-fat and high-fat meal. Non-compartmental PK, PD, and PKPD correlation were evaluated. Following single oral doses, systemic exposure increased in a linear manner and demonstrated 1:1 dose-proportional, first-order linear PK above 1.5 mg/kg. VCS inhibited CN activity in a dose-related fashion with maximal inhibition peaking at 3.0 mg/kg. PKPD correlation indicated an EC50 of 78.3 ± 6.8 ng/mL. Administration of VCS with a low-fat and high-fat meal decreased Cmax by 29% and 53%, respectively, and AUCinf by 15% and 25%, respectively. Following ascending single doses of VCS, exposure increased in a linear fashion. A food effect on exposure was demonstrated, with a more pronounced effect following a high-fat meal. VCS concentrations were also found to correlate with CN activity.
Synapse-specific and neuregulin-induced transcription require an Ets site that binds GABPα/GABPβ (1998)

Localization of acetylcholine receptors (AChRs) to neuromuscular synapses is mediated by multiple pathways. Agrin, which is the signal for one pathway, stimulates a redistribution of previously unlocalized AChRs to synaptic sites. The signal for a second pathway is not known, but this signal stimulates selective transcription of AChR genes in myofiber nuclei located near the synaptic site. Neuregulin (NRG) is a good candidate for the extracellular signal that induces synapse-specific gene expression, since NRG is concentrated at synaptic sites and activates AChR gene expression in cultured muscle cells. Previous studies have demonstrated that 181 bp of 5' flanking DNA from the AChR delta-subunit gene are sufficient to confer synapse-specific transcription in transgenic mice and NRG responsiveness in cultured muscle cells, but the critical sequences within this cis-acting regulatory region have not been identified. We transfected AChR delta-subunit-hGH gene fusions into a muscle cell line, and we show that a potential binding site for Ets proteins is required for NRG-induced gene expression. Furthermore, we produced transgenic mice carrying AChR delta-subunit-hGH gene fusions with a mutation in this NRG-response element (NRE), and we show that this NRE is necessary for synapse-specific transcription in mice. The NRE binds proteins in myotube nuclear extracts, and nucleotides that are important for NRG responsiveness are likewise critical for formation of the protein-DNA complex. This complex contains GABPalpha, an Ets protein, and GABPbeta, a protein that lacks an Ets domain but dimerizes with GABPalpha, because formation of the protein-DNA complex is inhibited by antibodies to either GABPalpha or GABPbeta. These results demonstrate that synapse-specific and NRG-induced gene expression require an Ets-binding site and suggest that GABPalpha/GABPbeta mediates the transcriptional response of the AChR delta-subunit gene to synaptic signals, including NRG.
Comments on “An Essay on Contact Angle Measurements” by Strobel and Lyons (2011)

Abstract The potential of contact angle measurements (CAM) as an analytical tool to characterize surface treatments or modifications is often not fully exploited. Agreeing with Strobel and Lyons, comparing contact angles is often much more reasonable than comparing deduced data like surface energies, because the latter are based on models, in turn involving the influence and knowledge of intermolecular forces at the respective interfaces. For a comprehensive picture, the measurement of contact angles itself has to be considered together with the appropriate model and the available techniques to carry out CAM. An appropriate measurement procedure will be given and a brief discussion of some models to derive free surface energy from CAM.
Theoretical Study of the Addition of Hydrogen Cyanide to Methanimine in the Gas Phase and in Aqueous Solution (1999)

We have performed a detailed study of the title reaction, which is the key step of one of the most realistic processes suggested for the prebiotic synthesis of amino acids. From a methodological point of view, our results confirm the reliability of the integrated computational tool formed by the B3LYP density functional model and the polarizable continuum model for the description of solvent effects. From a more chemical point of view, the reaction is quite unlikely in the gas phase due to the presence of significant reaction barriers, whereas the aqueous medium leads to a more feasible mechanism thanks to the preferential solvation of zwitterionic transition structures. Both specific and bulk solvent effects play a role in determining the overall mechanism.
Regulation of Complexed and Free Catenin Pools by Distinct Mechanisms (1997)

Cadherins are transmembrane receptors with an extracellular domain that participates in homophilic cell to cell adhesion and a cytoplasmic domain that associates with proteins called catenins. Cadherin-mediated adhesion as well as adhesion-independent functions for catenins play important roles in differentiation, development, and malignant transformation. Mechanisms that regulate steady-state catenin levels and cadherin-catenin complex stability are poorly understood, but activities of both the Wnt-1 proto-oncogene and tyrosine kinases are implicated. Here I define, at the biochemical level, distinct mechanisms that modulate steady-state catenin levels. Increased cadherin expression, providing more catenin binding sites, leads to selective stabilization of the cadherin-associated population of alpha- and beta-catenin, but not p120(cas). In contrast, expression of Wnt-1 leads primarily to increased stability of the uncomplexed pool of beta-catenin without effect on p120(cas). Significantly, the Wnt-1-induced stabilization of uncomplexed beta-catenin is independent of cadherin expression. Transformation by v-Src does not disrupt the catenin-cadherin complex despite the phosphorylation of E-cadherin and beta-catenin on tyrosine. In contrast to the effects of Wnt-1, v-Src does not modulate the uncomplexed population of beta-catenin. p120(cas) is phosphorylated on tyrosine by v-Src, and this is accompanied by a significant decrease in the level of uncomplexed p120(cas) as well as a change in behavior of p120(cas) upon biochemical fractionation. Taken together these data suggest that p120(cas) and beta-catenin are regulated independently.
MONSTER v1.1: a tool to extract and search for RNA non-branching structures (2015)

We present an application of MONSTER v1.1 on lincRNAs, which are a specific class of lncRNAs located in genomic regions which do not overlap protein-coding genes. In particular, we provide reliable predictions of the shared chains between HOTAIR, ANRIL and COLDAIR. The latter are lincRNAs which interact with the same protein complexes of the Polycomb group and hence they are expected to share structural motifs.
Electrocardiographic Predictors of Sudden Cardiac Death in Patients with Left Ventricular Hypertrophy (2012)

Geochemical Characteristics of Tailings from Typical Metal Mining Areas in Tibet Autonomous Region (2022)

With the exploring and developing of mineral resources in the Tibet Autonomous Region for many years, a large number of tailings have been produced. A total of 17 tailings samples from borehole cores were collected from different tailings ponds in different regions of Tibet. The results showed that the mineral composition and content of tailings in each research area were different. Among them, quartz was the most abundant mineral in most tailings. The major elements of tailings mainly included Si, Al, Fe, Mg, Mn, Ca, Na, K and so on. S existed in different types of tailings. In the analysis of trace element composition, it was found that the content of some elements had approached the lowest industrial grade, which has potential recycling value, such as Mn, Zn, Pb and P. Through the detection of radioactive elements (Ra-226, Th-232 and K-40), it was shown that there were great differences among different types of tailings, and their different contents would bring potential hazards to the safety of the surrounding environment and human health. Similar results were found in the analysis of particle size characteristics of tailings. These results are of great significance for the future utilization and resource utilization of tailings pond.
