description: Selective caries excavation may support pulp preservation. This in vitro study investigated the influence of selective removal of demineralized dentin on marginal integrity of composite restorations as determined by dye penetration. Dentinal caries-like lesions were produced in the approximal surfaces of 40 extracted human molars (ethylenediaminetetraacetate, 0.5 M, 96 h). The following test procedures were established: complete excavation, selective excavation, and caries-free control. Two class II cavities with enamel at the cervical margins were prepared per tooth and demineralization volume was determined by micro-computed tomography for the purpose of a stratified distribution to receive complete excavation or selective excavation. After complete or selective excavation (30 cavities each), adhesive composite restorations were placed. Cavities without demineralized dentin (20 cavities) served as control. The marginal integrity of restorations was evaluated by dye penetration with and without thermocycling or mechanical loading. Results were analyzed by non-parametrical statistical tests (Mann-WhitneyUTest) with an alpha = 0.05 level of significance. Dye penetration did not differ significantly among completely excavated, selectively excavated, or undemineralized teeth, but was increased by thermocycling and mechanical loading in all experimental groups. Selective caries removal did not increase marginal penetration in class II restorations. The presence of remaining demineralized dentin surrounded by sound dentin did not impair marginal integrity of restorations with margins placed in sound enamel.
Quantifying the Reliability of a PMU Network

The wide area measurement system (WAMS) is gradually becoming an important guarantee of security and stability in smart transmission grids. In the utility industry, WAMS is sometimes referred to as a PMU (phasor measurement unit) network, as synchronized PMUs are the most crucial elements in collecting real-time monitoring information. A PMU network provides much better observability and controllability in smart grid operations. However, like any other physical system, a PMU network itself can fail. The consequences of PMU network failure are serious and can include a large blackout. Therefore, the reliability of PMU networks should be quantitatively evaluated and assured.

description: We study a Cahn-Hilliard-Hele-Shaw (or Cahn-Hilliard-Darcy) system for an incompressible mixture of two fluids. The relative concentration difference $φ$ is governed by a convective nonlocal Cahn-Hilliard equation with degenerate mobility and logarithmic potential. The volume averaged fluid velocity $\mathbf{u}$ obeys a Darcy's law depending on the so-called Korteweg force $μ\nabla φ$, where $μ$ is the nonlocal chemical potential. In addition, the kinematic viscosity $η$ may depend on $φ$. We establish first the existence of a global weak solution which satisfies the energy identity. Then we prove the existence of a strong solution. Further regularity results on the pressure and on $\mathbf{u}$ are also obtained. Weak-strong uniqueness is demonstrated in the two dimensional case. In the three-dimensional case, uniqueness of weak solutions holds if $η$ is constant. Otherwise, weak-strong uniqueness is shown by assuming that the pressure of the strong solution is $α$-Hölder continuous in space for $α\in (1/5,1)$.

description: ORIENT-16, a phase III clinical trial conducted at 62 hospitals in China, reported that add-on sintilimab (Sin) to chemotherapy (Chemo) had favorable efficacy (p < 0.05) for patients with advanced HER2-negative gastric or gastroesophageal junction cancer (GC/GEJC). This study aimed to evaluate the cost-utility of the Sin+Chemo based on results of ORIENT-16 from the perspective of Chinese healthcare payers. A three-state partitioned survival model was developed to simulate the 10-year life expectancy and total healthcare costs for patients with advanced HER2-negative GC/GEJC. Primary measure outcomes were: cost, quality-adjusted life-years (QALYs), and incremental cost-utility ratios (ICURs). Sensitivity/scenario analyses were conducted to assess the model robustness. In all patients, Sin+Chemo vs Chemo increased costs by $6,472, additionally providing 0.61 QALYs, resulting in an ICUR of $10,610/QALY. While, in PD-L1 combined positive score ≥ 5 cohort, the ICUR was $9,738/QALYs. The ICUR was most sensitive to the utility of progression-free survival. The probabilistic sensitivity analysis showed that add-on Sin had a 100% probability of being cost-effective at a willingness-to-pay threshold of $18,625/QALY gained. Sin+Chemo is a cost-effective first-line treatment option for advanced HER2-negative GC/GEJC in China. ORIENT-16, www.clinicaltrials.gov, identifier is NCT03745170.

description: A complete manual search has been carried out of the list of 285423 objects, nearly all of them galaxies, identified in the COSMOS field that are brighter than I=25. Two certain and one highly probable new gravitational lenses are found, in addition to the lenses and candidate lens systems previously found by Faure et al. (2008). A further list of 112 candidate lens systems is presented. Few of these are likely to be true gravitational lens systems, most being star-forming rings or pairs of companion galaxies. It is possible to examine of order 10^6 objects by eye in a reasonable time, although reliable detection of lenses by such methods is likely to be possible only with high-resolution data. The loss of completeness involved in a rapid search is estimated as up to a factor of 2, depending on the morphology of the lens candidate.

Gravitational collapse from cold uniform asymmetric initial conditions

description: Using controlled numerical N-body experiments, we show how, in the collapse dynamics of an initially cold and uniform distribution of particles with a generic asymmetric shape, finite $N$ fluctuations and perturbations induced by the anisotropic gravitational field compete to determine the physical properties of the asymptotic quasi-stationary state. When finite $N$ fluctuations dominate the dynamics, the particle energy distribution changes greatly and the final density profile {decays outside its core} as $r^{-4}$ with an $N$-dependent amplitude. On the other hand, in the limit where the anisotropic perturbations dominate, the collapse is softer and the density profile shows a decay as $r^{-3}$, as is typical of halos in cosmological simulations. However, even in this limit, convergence with $N$ of the macroscopic properties of the virialized system, such as the particle energy distributions, the bound mass, and the density profile, is very slow and not clearly established, including for our largest simulations (with $N \sim 10^6$). Our results illustrate the challenges of accurately simulating the first collapsing structures in standard-type cosmological models

description: We present the detection of deuterated molecular hydrogen (HD) in the remote Universe in a damped Lyman-alpha cloud at zabs=2.418 toward the quasar SDSS J143912.04+111740.5. This is a unique system in which H2 and CO molecules are also detected. The chemical enrichment of this gas derived from ZnII and SII is as high as in the Sun. We measure N(HD)/2 N(H2)=1.5+0.6-0.4 x 10^-5, which is significantly higher than the same ratio measured in the Galaxy and close to the primordial D/H ratio estimated from the WMAP constraint on the baryonic matter density Omega_b. This indicates a low astration factor of deuterium that contrasts with the unusually high chemical enrichment of the gas. This can be interpreted as the consequence of an intense infall of primordial gas onto the associated galaxy. Detection of HD molecules at high-z also opens the possibility to obtain an independent constraint on the cosmological-time variability of mu, the proton-to-electron mass ratio.

Emergence of Kinematic Space from Quantum Modular Geometric Tensor

Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We generalize the Quantum Geometric Tensor by replacing a Hamiltonian with a modular Hamiltonian. The symmetric part of the Quantum Geometric Tensor provides a Fubini-Study metric, and its anti-symmetric sector gives a Berry curvature. Now the generalization or Quantum Modular Geometric Tensor gives a Kinematic Space and a modular Berry curvature. Here we demonstrate the emergence by focusing on a spherical entangling surface. We also use the result of the identity Virasoro block to relate the connected correlator of two Wilson lines to the two-point function of a modular Hamiltonian. This result realizes a novel holographic entanglement formula for two intervals of a general separation. This formula does not only hold for a classical gravity sector but also Quantum Gravity. The formula also provides a new Quantum Information interpretation to the connected correlators of Wilson lines as the mutual information. Our study provides an opportunity to explore Quantum Kinematic Space through Quantum Modular Geometric Tensor and hence go beyond symmetry.

In situ a reaction was shown. The capacity od the reaction is caused by an herbivor, called Metheisa lucillodes. She hurts the stem by prozess of egg-laying and could be a trigger for the plant sending VOCS. Further the concentration between Myrmecophyts and Non-Myrmecophyts was checked.

Year: 2017

Newsletter
Europe is ahead of the world's other highly industrialized areas in planning for the smart grid. A well-elaborated vision, developed in the framework of European Union institutions, anticipates that the traditional distinction between transmission and T&D will blur and disappear, and that the end-user will more and more become a "prosumer", producing as well as consuming energy locally. Europe's 2020 targets for renewable generation will only be achievable, in fact, if smart grid features are exploited to the fullest.

description: Gigahertz-Peaked Spectrum (GPS) sources are probably the precursors of local radio galaxies.Existing GPS source samples are small (<200). It is necessary to extend the availabe sample of the Gigahertz-Peaked Spectrum (GPS) and High Frequency Peaker (HFP) sources in order to study their nature with greater details and higher statistical significance. A sample of 214 radio sources, which were extracted from the SPECFIND catalog and show an inverted radio spectrum, were observed quasi-simultaneously at 4.85, 10.45, and 32GHz with the 100-m Effelsberg radio telescope. Using the VLBA calibrator survey (VCS) we have investigated the parsec-scale morphology of the sources. About 45% of the sources in our sample are classified as GPS or HFP candidates. We add 65 new GPS/HFP candidates to existing samples. We confirm the expected tendency that HFP are more compact on milliarcsecond scale than the 'classical' GPS sources, which peak at lower frequencies. The data mining of the SPECFIND database represents a promising tool for the discovery of new GPS/HFP sources.

description: The accurate measurement of blood pressure (BP) is an important prerequisite for the reliable diagnosis and efficient management of hypertension and other medical conditions. Office Blood Pressure Measurement (OBP) is a technique performed in-office with the sphygmomanometer, while Ambulatory Blood Pressure Monitoring (ABPM) is a technique that measures blood pressure during 24h. The BP fluctuations also depend on other factors such as physical activity, temperature, mood, age, sex, any pathologies, a hormonal activity that may intrinsically influence the differences between OBP and ABPM. The aim of this study is to examine the possible influence of sex on the discrepancies between OBP and ABPM in 872 subjects with known or suspected hypertension. A significant correlation was observed between OBP and ABPM mean values calculated during the day, night and 24h (ABPMday, ABPMnight, ABPM24h) in both groups (p<0.0001). The main finding of this study is that no difference between sexes was observed in the relation between OBP and mean ABMP values except between systolic OBP and systolic ABPM during the night. In addition, this study showed a moderate correlation between BPs obtained with the two approaches with a great dispersion around the regression line which suggests that the two approaches cannot be used interchangeably.

Chemical modification of carboxyl groups in porcine pepsin
Creators: name: Ma, Ching-Yung
Publisher: name: University of British Columbia
Year: 2010

description: Carboxyl groups in porcine pepsin were chemically modified "by the carbodiimide reaction using waterrsoluble l-ethyl-3-(3-dimethylaminopropyl) carbodiimide and amino acid esters as nucleophiles. The modification resulted in profound changes in the activities, specificity and some physico-chemical properties of the enzyme. These include (1) significant decrease in milk clotting activity without changes in proteolytic activity against hemoglobin; (2) decrease in peptidase activity against N-acetyl-L-phenylalanyl-diiodo-L-tyrosine; (3) increase in clotting activity against k-casein but decrease in clotting activity against K-α sl⁻casein mixture; (4) shift -in proteolytic pH profile with pH optimum increased from 2.0 to about 3.5; (5) decrease in relative electrophoretic mobility and a slight decrease in isoelectric point; (6) increase in Km without much change in kcat; and (7) increase in stability at pH above 6.0. Results suggest that the drop in milk clotting activity was due to a change in the charge distribution on the enzyme affecting enzyme-micelle interaction. The presence of dipeptide substrates interfered with the carboxyl modification suggestive of the proximity of the modified groups to the enzyme active site. The modified enzyme remained reactive to site-specific inactivators but at rates slower than the native enzyme. The modification was not specific, causing similar changes in pepsinogen and chymosin. The modified and native pepsins had similar caseinolytic properties and produced comparable rates of syneresis and curd tension development on curdled milk. The increase in pH stability suggested that the modified enzyme may be a better calf rennet substitute than native pepsin for cheese-making.

description: We study Wilson loop operators in three-dimensional, N=6 superconformal Chern-Simons theory dual to IIA superstring theory on AdS4 x CP3. Novelty of Wilson loop operators in this theory is that, for a given contour, there are two linear combinations of Wilson loop transforming oppositely under time-reversal transformation. We show that one combination is holographically dual to IIA fundamental string, while orthogonal combination is set to zero. We gather supporting evidences from detailed comparative study of generalized time-reversal transformations in both D2-brane worldvolume and ABJM theories. We then classify supersymmetric Wilson loops and find at most 1/6-supersymmetry. We next study Wilson loop expectation value in planar perturbation theory. For circular Wilson loop, we find features remarkably parallel to circular Wilson loop in N=4 super Yang-Mills theory in four dimensions. First, all odd loop diagrams vanish identically and even loops contribute nontrivial contributions. Second, quantum corrected gauge and scalar propagators take the same form as those of N=4 super Yang-Mills theory. Combining these results, we propose that expectation value of circular Wilson loop is given by Wilson loop expectation value in pure Chern-Simons theory times zero-dimensional Gaussian matrix model whose variance is specified by an interpolating function of `t Hooft coupling. We suggest the function interpolates smoothly between weak and strong coupling regime, offering new test ground of the AdS/CFT correspondence.

description: The current analysis aimed to evaluate the economic benefit of toripalimab plus axitinib for previously untreated RCC patients from the Chinese healthcare system perspective. The partitioned survival model was developed to simulate 3-week patients’ transition in 20-year time horizon to evaluate the cost-effectiveness of toripalimab plus axitinib compared with sunitinib for advanced RCC. Survival data were gathered from the RENOTORCH trial, and cost and utility inputs were obtained from the database and published literature. Total cost, life-years (LYs), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) were the model outputs. Subgroup analyses and sensitivity analyses were conducted to increase the comprehensiveness and estimate the robustness of the model results. In the base-case analysis, compared with sunitinib, toripalimab plus axitinib could bring additional 1.19 LYs and 0.65 QALYs, with the marginal cost of $41,499.23, resulting in the ICER of $64,337.49/QALY, which is higher than the WTP threshold. And ICERs were always beyond the WTP threshold of all subgroups. Sensitivity analyses demonstrated the model results were robust. Toripalimab plus axitinib was unlikely to be the cost-effective first-line therapy for patients with previously untreated advanced RCC compared with sunitinib from the Chinese healthcare system perspective.

title: Land, family and community in Wingham and its environs: an economic and social history of rural society in East Kent from C.1450-1640
Creators: name: Andrewes, E. Jane
Publisher: name: University of Kent
Year: 2021

description: The thesis is a social and economic study of five contiguous parishes in East Kent, which for the most part formed the estate of the Archbishop of Canterbury at Wingham, the central community of this area, a market village, quasi small town in an area of hamlet communities and isolated farms situated mid way between Canterbury and the port of Sandwich. The topography of this area and its importance as a determining factor in the social and economic structure is outlined. Lordship in this area and the structure of the Wingham estate is traced through the medieval period to the 17th century, revealing the disintergration of an unusally large, medieval, ecclesiastical estate and the emergence of the small estate pattern, more typical of East Kent. The nature o fthese estates continuity and change among resident gentry families and their status, wealth and influence in the locality is considered. The changing pattern of landholding and the ground plan of farms is uncovered, indicating both compact, enclosed units and farms with dispersed arabic parcels in open fields and detached marshland; the influence of demographic trends and inheritance strategies is discussed suggesting long term piecemeal consolidation. The economic structure of this area, situated within the relatively urbanised south east is considered in terms of agriculture, family farms, rural trade occupations, a rural cloth industry, marketing, consumption and local credit. It revealed an intensive and flexible agrarian system with individual autonomy and diversity in family enterprises. The nature of community is examined in terms of general population trends, place and community focus, neighbourhood relationships, networks and urban connections. This study depended on a variety of local sources, in particular a rich survival of probate records, which made possible a biographical method reconstruction and use of case studies.

When applied to the quaternionic Wigner and Wishart families of random matrices the result gives the duality between moments of these families and the corresponding real Wigner and Wishart families.

description: Supervised machine learning, in which models are automatically derived from labeled training data, is only as good as the quality of that data. This study builds on prior work that investigated to what extent 'best practices' around labeling training data were followed in applied ML publications within a single domain (social media platforms). In this paper, we expand by studying publications that apply supervised ML in a far broader spectrum of disciplines, focusing on human-labeled data. We report to what extent a random sample of ML application papers across disciplines give specific details about whether best practices were followed, while acknowledging that a greater range of application fields necessarily produces greater diversity of labeling and annotation methods. Because much of machine learning research and education only focuses on what is done once a "ground truth" or "gold standard" of training data is available, it is especially relevant to discuss issues around the equally-important aspect of whether such data is reliable in the first place. This determination becomes increasingly complex when applied to a variety of specialized fields, as labeling can range from a task requiring little-to-no background knowledge to one that must be performed by someone with career expertise.

As we all know, today's smart grid initiatives have given rise to multiple emerging products and services from a growing number of suppliers. Utilities want choices among vendors' products. As smart grid technologies mature, the need to ensure interoperability of products from multiple vendors will become significant. Although standards-setting organizations strive to provide a level of safety, quality and consistence in their products, traditional laboratory environments cannot guarantee that products form multiple vendors will interoperate smoothly when combined in the real world. As smart grid interoperability standards are relatively new on the scene, it is all the more important to ensure the end-to-end integration and compatibility of technologies to be deployed.

Newsletter
Machine learning techniques can be applied to sensor data collected from smart homes to reveal activity patterns of the residents, which can then be correlated with measured energy consumption. By associating activities with energy use and costs, intelligent systems can be devised to automatically control home environments so as to improve energy efficiency and cut expenses.
The Magellanic Group and the Seven Dwarfs

description: The Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. This group, dominated by the LMC, contained ~4% of the mass of the Milky Way prior to its accretion and tidal disruption, but ~70% of the known dwarfs orbiting the MW. Our theory addresses many outstanding problems in galaxy formation associated with dwarf galaxies. First, it can explain the planar orbital configuration populated by some dSphs in the MW. Second, it provides a mechanism for lighting up a subset of dwarf galaxies to reproduce the cumulative circular velocity distribution of the satellites in the MW. Finally, our model predicts that most dwarfs will be found in association with other dwarfs. The recent discovery of Leo V (Belokurov et al. 2008), a dwarf spheroidal companion of Leo IV, and the nearby dwarf associations supports our hypothesis.

description: This study aims to provide a comprehensive assessment of economic and health-related quality of life (HRQoL) outcomes for human epidermal growth factor receptor 2 (HER2)-positive, early-stage breast cancer patients treated with trastuzumab-containing regimens, by focusing on both Incremental Cost-Effectiveness Ratios (ICERs) and quality-adjusted life years (QALYs). A systematic search was conducted across PubMed, Embase, and Scopus databases without language or publication year restrictions. Two independent reviewers screened eligible studies, extracted data, and assessed methodology and reporting quality using the Drummond checklist and Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022), respectively. Costs were converted to US dollars (US$) for 2023 for cross-study comparison. Twenty-two articles, primarily from high-income countries (HICs), were included, with ICERs ranging from US$13,176/QALY to US$254,510/QALY, falling within country-specific cost-effectiveness thresholds. A notable association was observed between higher QALYs and lower ICERs, indicating a favorable cost-effectiveness and health outcome relationship. EQ-5D was the most utilized instrument for assessing health state utility values, with diverse targeted populations. Studies reporting higher QALYs tend to have lower ICERs, indicating a positive relationship between cost-effectiveness and health outcomes. However, challenges such as methodological heterogeneity and transparency in utility valuation persist, underscoring the need for standardized guidelines and collaborative efforts among stakeholders.

description: Entangled states of pseudoscalar mesons represent a very interesting tool for studying foundations of quantum mechanics, e.g. for testing Bell inequalities. Recently, they also emerged as a test bench for quantum information protocols. On the other hand, from a quantum information point of view, the characterization of the distance between two quantum states is a topic of the utmost importance. In this letter, with the purpose of providing a useful tool for further investigations, we address the problem of which distance allows a better discrimination between density matrices appearing in pseudoscalar phenomenology.

The long idle time of electric vehicles (EVs) during charging and discharging does not comport well with future scenarios in which EVs play a big role. Though fast charging is a proposed solution to this problem, it has some drawbacks such as drawing excessive current and harming battery lifetime. Battery swapping is a promising solution.
Constraints on the Local Sources of Ultra High-Energy Cosmic Rays

Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Ultra high-energy cosmic rays (UHECRs) are believed to be protons accelerated in magnetized plasma outflows of extra-Galactic sources. The acceleration of protons to ~10^{20} eV requires a source power L>10^{47} erg/s. The absence of steady sources of sufficient power within the GZK horizon of 100 Mpc, implies that UHECR sources are transient. We show that UHECR "flares" should be accompanied by strong X-ray and gamma-ray emission, and that X-ray and gamma-ray surveys constrain flares which last less than a decade to satisfy at least one of the following conditions: (i) L>10^{50} erg/s; (ii) the power carried by accelerated electrons is lower by a factor >10^2 than the power carried by magnetic fields or by >10^3 than the power in accelerated protons; or (iii) the sources exist only at low redshifts, z<<1. The implausibility of requirements (ii) and (iii) argue in favor of transient sources with L>10^{50} erg/s.

A study of over a dozen microgrid projects inaugurated by seven developers in three countries sought to determine why some such projects get trapped in vicious cycles of poor maintenance, disappointed customers, insufficient revenue and dysfunctional community support, while others prosper. Seven key factors are identified: tariff design, tariff collection mechanisms, maintenance and contractor performance, theft management, demand growth, load limits and local training and institutionalization.

description: Star formation induced by a spiral shock wave, which in turn is generated by a spiral density wave, produces an azimuthal age gradient across the spiral arm, which has opposite signs on either side of the corotational resonance. An analysis of the spatial separation between young star clusters and nearby HII regions made it possible to determine the position of the corotation radius in the studied galaxies. Fourier analysis of the gas velocity field in the same galaxies independently confirmed the corotation radius estimates obtained by the morphological method presented here.

description: We describe the construction of a database of extremely metal-poor (EMP) stars in the Galactic halo whose elemental abundances have been determined. Our database contains detailed elemental abundances, reported equivalent widths, atmospheric parameters, photometry, and binarity status, compiled from papers in the recent literature that report studies of EMP halo stars with [Fe/H] < -2.5. The compilation procedures for this database have been designed to assemble the data effectively from electronic tables available from online journals. We have also developed a data retrieval system that enables data searches by various criteria, and permits the user to explore relationships between the stored variables graphically. Currently, our sample includes 1212 unique stars (many of which are studied by more than one group) with more than 15000 individual reported elemental abundances, covering all of the relevant papers published by December 2007. We discuss the global characteristics of the present database, as revealed by the EMP stars observed to date. For stars with [Fe/H] < -2.5, the number of giants with reported abundances is larger than that of dwarfs by a factor of two. The fraction of carbon-rich stars (among the sample for which the carbon abundance is reported) amount to ~30 % for [Fe/H] < -2.5. We find that known binaries exhibit different distributions of orbital period, according to whether they are giants or dwarfs, and also as a function of metallicity, although the total sample of such stars is still quite small.

Phasor Measurement Units (PMUs), which measure voltage and current synchronized phasors (synchrophasors), along with frequency and rate of change of frequency (ROCOF), are the emerging measurement devices for power network monitoring. Introduced in the late 1980s and first deployed in experimental systems in the early 1990s, they are now assuming a key role in protection and control of modern electric grids, in particular for state estimation in transmission networks.
