description: We recently presented a new statistical method to constrain the physics of star formation and feedback on the cloud scale by reconstructing the underlying evolutionary timeline. However, by itself this new method only recovers the relative durations of different evolutionary phases. To enable observational applications, it therefore requires knowledge of an absolute 'reference time-scale' to convert relative time-scales into absolute values. The logical choice for this reference time-scale is the duration over which the star formation rate (SFR) tracer is visible because it can be characterised using stellar population synthesis (SPS) models. In this paper, we calibrate this reference time-scale using synthetic emission maps of several SFR tracers, generated by combining the output from a hydrodynamical disc galaxy simulation with the SPS model SLUG2. We apply our statistical method to obtain self-consistent measurements of each tracer's reference time-scale. These include H$α$ and 12 ultraviolet (UV) filters (from GALEX, Swift, and HST), which cover a wavelength range 150-350 nm. At solar metallicity, the measured reference time-scales of H$α$ are ${4.32^{+0.09}_{-0.23}}$ Myr with continuum subtraction, and 6-16 Myr without, where the time-scale increases with filter width. For the UV filters we find 17-33 Myr, nearly monotonically increasing with wavelength. The characteristic time-scale decreases towards higher metallicities, as well as to lower star formation rate surface densities, owing to stellar initial mass function sampling effects. We provide fitting functions for the reference time-scale as a function of metallicity, filter width, or wavelength, to enable observational applications of our statistical method across a wide variety of galaxies.

International Benchmarking of Electricity Transmission by Regulators: Theory and Practice
Creators: name: Brophy Haney, Aoife

Subjects: Electricity transmission; benchmarking; regulation

description: Benchmarking of electricity networks has a key role in sharing the benefits of efficiency improvements with consumers and ensuring regulated companies earn a fair return on their investments. This paper analyses the theory and practice of international benchmarking of electricity transmission by regulators. We examine the literature relevant to electricity transmission benchmarking and conduct a survey of 48 national electricity regulators. Consideration of the literature and our survey indicates that electricity transmission benchmarking is significantly more challenging than electricity distribution benchmarking. New panel data techniques aimed at dealing with unobserved heterogeneity and the validity of the comparator group look intellectually promising but are in their infancy for regulatory purposes. In electricity transmission choosing variables is particularly difficult, because of the large number of potential variables to choose from. Failure to apply benchmarking appropriately may negatively affect investors’ willingness to invest in the future. While few of our surveyed regulators acknowledge that regulatory risk is currently an issue in transmission benchmarking, many more concede it might be. New regulatory approaches – such as those based on tendering, negotiated settlements, a wider range of outputs or longer term grid planning - are emerging and will necessarily involve a reduced role for benchmarking.
On the possibility of radar echo detection of ultra-high energy cosmic ray- and neutrino-induced extensive air showers

description: We revisit and extend the analysis supporting a 60 year-old suggestion that cosmic rays air showers resulting from primary particles with energies above 10^{18} eV should be straightforward to detect with radar ranging techniques, where the radar echoes are produced by scattering from the column of ionized air produced by the shower. The idea has remained curiously untested since it was proposed, but if our analysis is correct, such techniques could provide a significant alternative approach to air shower detection in a standalone array with high duty cycle, and might provide highly complementary measurements of air showers detected in existing and planned ground arrays such as the Fly's Eye or the Auger Project. The method should be particularly sensitive to showers that are transverse to and relatively distant from the detector, and is thus effective in characterizing penetrating horizontal showers such as those that might be induced by ultra-high energy neutrino primaries.

description: Collective coordinates in a many-particle system are complex Fourier components of the particle density, and often provide useful physical insights. However, given collective coordinates, it is desirable to infer the particle coordinates via inverse transformations. In principle, a sufficiently large set of collective coordinates are equivalent to particle coordinates, but the nonlinear relation between collective and particle coordinates makes the inversion procedure highly nontrivial. Given a "target" configuration in one-dimensional Euclidean space, we investigate the minimal set of its collective coordinates that can be uniquely inverted into particle coordinates. For this purpose, we treat a finite number $M$ of the real and/or the imaginary parts of collective coordinates of the target configuration as constraints, and then reconstruct "solution" configurations whose collective coordinates satisfy these constraints. Both theoretical and numerical investigations reveal that the number of numerically distinct solutions depends sensitively on the chosen collective-coordinate constraints and target configurations. From detailed analysis, we conclude that collective coordinates at the $\lceil\frac{N}{2}\rceil$ smallest wavevectors is the minimal set of constraints for unique inversion, where $\lceil{\cdot}\rceil$ represents the ceiling function. This result provides useful groundwork to the inverse transform of collective coordinates in higher-dimensional systems.

description: Using a Generic spin basis, we present a general formalism of one-loop radiative corrections to the spin correlations in the top quark pair production at the Next Linear Collider, and calculate the O(α_s) QCD corrections under the soft gluon approximation. We find that: (a) in Off-diagonal basis, the $O(α_s)$ QCD corrections to $e_L^- e^+$ ($e_R^- e^+$) scattering process increase the differential cross sections of the dominant spin component $t_{\uparrow}\bar{t}_{\downarrow}$ ($t_{\downarrow}\bar{t}_{\uparrow}$) by $\sim 30%$ and $\sim (0.1%-3%)$ depending on the scattering angle for $\sqrt{s}=400 GeV$ and 1 TeV, respectively; (b) in {Off-diagonal basis} (Helicity basis), the dominant spin component makes up 99.8% ($\sim 53%$) of the total cross section at both tree and one-loop level for $\sqrt{s}=400 GeV$, and the Off-diagonal basis therefore remains to be the optimal spin basis after the inclusion of $O(α_s)$ QCD corrections.

description: Radix Rehmanniae (RR) is the root tuber of Rehmannia glutinosa Libosch. Herein, the methanol extracts of dried RR (DRR) and processed RR (PRR) were partitioned to obtain ethyl acetate, aqueous, and n-butanol layers. The angiotensin-I converting enzyme (ACE) inhibition test indicated that the ethyl acetate extracts of DRR (DRRE) and PRR (PRRE) show better inhibitory activity. Therefore, changes in blood pressure were tested over 24 h in spontaneously hypertensive rats, with DRR showing good anti-hypertensive activity. DRRE was further subjected to column chromatography; 28 fractions were separated and tested for ACE inhibition. Ultimately, six compounds were identified by spectral analysis, and literature comparison. Specifically, ursolic acid and oleanolic acid showed better ACE inhibition than the other compounds. This study confirmed that DRR has anti-hypertensive activity. In future, DRR’s potential as a health food should be further assessed.

description: An unobserved components model in which the signal is buried in noise that is non-Gaussian may throw up observations that, when judged by the Gaussian yardstick, are outliers. We describe an observation driven model, based on a conditional Student t-distribution, that is tractable and retains some of the desirable features of the linear Gaussian model. Letting the dynamics be driven by the score of the conditional distribution leads to a specification that is not only easy to implement, but which also facilitates the development of a comprehensive and relatively straightforward theory for the asymptotic distribution of the ML estimator. The methods are illustrated with an application to rail travel in the UK. The .final part of the article shows how the model may be extended to include explanatory variables.

description: The time-dependent variational principle proposed by Balian and Veneroni is used to provide the best approximation to the generating functional for multi-time Green's functions of a set of (bosonic) observables $Q_{μ)$. By suitably restricting the trial spaces, the computation of the two-time Green's function, obtained by a second order expansion in the sources, is considerably simplified. This leads to a tractable formalism suited to quantum fields out of equilibrium. We propose an illustration on the finite temperature ${\bfΦ^4}$ theory in curved space and coupled to gravity.

description: Iron-titanium sulfides FeTi2S4 and Fe2TiS4 have been structurally and magnetically characterized using powder X Ray Diffraction with Rietveld refinement method and 57Fe Mössbauer spectroscopy at variable temperature. Both sulfides have the same crystallographic phase, based on the monoclinic Cr3S4 type structure and vary in atomic coordinates; FeTi2S4 retains the ideal atomic positions proposed for the Cr3S4 phase, while in Fe2TiS4 the metal displacements from ideal sites are noticeable. Mössbauer spectra reveal different magnetic behaviors; in FeTi2S4 there is a transition from paramagnetic to magnetic ordering at temperature Tc = 145 K, giving rise to unusually low hyperfine magnetic field of 2.5 T (at 77 K) if compared with values of iron magnetic moments reported previously, this behavior is explained on the basis of blocking Fe localized magnetic moments by the Spin density wave (SDW) originated from 3d Ti atoms. In Fe2TiS4 a transition from paramagnetic to (SDW) arises at Tc = 290 K, the SDW is spread in both Fe and Ti metals through [101] crystallographic plane and undergoes a transition of first order from Incommensurate SDW (ISWD) to Commensurate SDW (CSDW) at TIC = 255 K. The atomic positions in the unit cell are correlated to the magnetic behavior in both sulfides.

description: Understanding plasma behavior in the dipole magnetic field geometry is important for various naturally-occurring and laboratory plasma environments. Charged particles in this geometry undergo more general particle trajectories than in straight-line magnetic fields, including chaotic orbits. An environment with such general particle motion provides a test-bed for electrostatic wave-scattering experiments in a plasma. Ion acoustic waves are launched far from a permanent dipole magnet and waves mode convert into electrostatic ion cyclotron waves as they approach the magnet. Waves may be reflected, absorbed, or scattered from plasma near a dipole magnet. Laser-induced fluorescence (LIF) techniques provide diagnostic methods for describing ion dynamics in low-temperature plasma as well as the ion response to electrostatic perturbations. In addition to cold and emitting Langmuir probes, LIF measurements are presented for the first time in a dipole magnetic field geometry to characterize the argon ion dynamics as well as ion acoustic wave scattering from dipole-confined plasma.

description: Cuminum cyminum is famous for its spicy fruits used for culinary and therapeutic properties worldwide. Brine shrimp test was performed for detecting cytotoxic fractions and subfractions. Ethyl acetate (EA) and hexane (HE) fractions demonstrated LC50 of 52.40 and 60.77 µg/ml against Artemia salina while other fractions showed no toxicity (LC50> 500 µg/ml). Bioguided elucidation of EA and HE fractions were carried out and cytotoxicity of pure compounds were investigated against breast cancer cell lines (MCF-7 and MDA-MB-231) and normal cell line (NIH/3T3) by MTT assay. Four flavone structures as luteolin, apigenin, luteolin-7-O-glucoside and apigenin-7-O-glucoside from EA and cuminoid A from HE were purified and identified. Luteolin-7-O-glucoside demonstrated potent anticancer activities against MCF-7 cell line (IC50 of 3.98 µg/ml) with selectivity index of 8.0. In conclusion, flavonoids especially luteolin-7-O-glucoside play a significant role in cytotoxic effect of C. cyminum fruits and can be introduced as candidate for chemopreventive and chemotherapeutic drugs.

description: The quantum Hall regime in a smooth random potential is considered when two disorder-broadened Zeeman levels overlap strongly. Spin-orbit coupling is found to cause a drastic change in the percolation network which leads to a strong enhancement of the dissipative conductivity at finite temperature, provided the Fermi level $E_F$ lies between the energies of two delocalized states $E=\pmΔ$, $2Δ$ being the Zeeman splitting. The conductivity is shown to exhibit a box-like behavior with changing magnetic field: $σ_{xx}$ is $\sim e^2/h$ at $|E_F|

Subjects: Energy-efficiency and environmental policy; income supplements; distributional impact; policy costs; targeting

description: The paper examines the financial costs of energy-efficiency and environmental policies that directly affect domestic electricity and gas bills in the UK over time. It also attempts for the first time to work out the current distributional impacts of these policies and others that act as income supplements thereby presenting a consistent picture across time and income deciles. Figures suggest that during 2000-11, the percentage share of policy costs in typical domestic electricity and gas bills rose by 14% and 4%, respectively. This reflects a growing share of policy costs in bills which is relatively small for gas customers but significant for electricity customers. Moreover, distributional impacts of the energy-policy mix highlight the issue of imperfect targeting of low-income households during 2009-10. The study also indicates that during 2010-11, 76% of the funds for energy-efficiency schemes were handled by the private sector. Given that a long-term solution to fuel poverty lies in improving thermal efficiency of houses; this research draws attention towards the need for definitive evidence on the ways in which energy suppliers charge policy costs from their domestic customers. This would facilitate in making the future policies more empirically grounded. In time, a clearer understanding of official statistics on energy bills will go a long way in restoring consumers’ trust in the pricing mechanism of the energy market.

description: Objective: The goals of this research are to: (i) investigate the contributing factors of major road traffic accidents using a human factors classification that follows the ideas of the human factors analysis and classification system (HFACS); (ii) quantitatively examine the relationships between the human factors of the cross levels in an entire system. Methods: This study examined 234 major road traffic accidents recorded in 27 Chinese provinces from 1997 to 2014. Odds ratio (OR) was used to quantitatively analyze the relationships among the contributing factors. Results: The frequencies of unsafe acts, violations, and inadequate regulation are the highest in five categories, 15 subcategories, and 63 indicators, respectively. This study has demonstrated a number of associations between the upper and adjacent lower levels. At the outside factors level, “failure to provide supervision for regulatory” can be viewed as a strong predictor to “formal accountability for actions,” “norms and rules,” and “values and beliefs.” At the organizational influences level, “formal accountability for actions,” “norms and rules,” and “values and beliefs” were strong predictors. At the unsafe supervision level, “failure to provide oversight,” “failure to initiate corrective action,” and “failure to enforce rules and regulations” had strong prediction on “fatigue driving.” At the preconditions for unsafe acts level, “visual limitation”, “fatigue driving,” and “vehicle faults” were strong predictors. Conclusions: The generic HFACS failure types were interpreted and applied successfully to the road safety context, and such examination of major accidents has provided significant findings concerning the main contributing factors of those accidents. Using the OR technique, this study has demonstrated a number of associations between the upper level and adjacent lower levels in the entire system and has found the routes to failure, which is particularly important for developing countermeasures and remediation strategies, as it ensures that these countermeasures are targeted to a wider range of systems. Furthermore, these findings demonstrate the efficiency and applicability of the HFACS as a retrospective tool for the analysis of major road traffic accidents.

description: Forests are significant terrestrial carbon sinks that play a crucial role in mitigating climate change by sequestering atmospheric carbon dioxide (CO2). Trees as the primary components of forests, have been extensively studied for their carbon sequestration potential. This review comprehensively explored the factors influencing tree carbon sequestration, the methodologies employed to measure and estimate carbon sequestration and the potential of trees in addressing climate change. The carbon sequestration potential of trees is influenced by various factors, including species-specific characteristics, stand age and structure, site conditions and management practices. Tree species possess inherent differences in their growth rates, photosynthetic efficiency and biomass allocation patterns, which directly impact their carbon sequestration capacity. Older, mature forests generally exhibit higher potential due to their larger biomass and slower growth rates. Site factors such as soil fertility, climate and topography also influence tree growth and carbon storage. Proper forest management practices, including silvicultural treatments and harvesting strategies, can optimize carbon sequestration by promoting tree health and growth. A variety of methodologies have been developed to measure and estimate tree carbon sequestration. Direct measurements involve destructive sampling to quantify aboveground and belowground biomass, while indirect methods utilize allometric equations, the mean ratio method (MRM), the biomass expansion factor (BEF) and remote sensing techniques. Trees have immense potential to sequester carbon and mitigate global climate change. Afforestation and reforestation initiatives can create new forest ecosystems, expanding the global carbon sink. Sustainable forest management practices can enhance carbon sequestration in existing forests while ensuring their long-term health and productivity. Tree-based carbon offset programs offer opportunities for individuals and organizations to reduce their carbon footprint by supporting tree planting and conservation projects.
The Photovoltaic Crisis and the Demand-side Generation in Spain

Publisher: name: Faculty of Economics

Subjects: Distributed on-site generation, net metering, Spain

description: The RES-E promotion policy in Spain gave priority to the photovoltaic (henceforth, PV) ground-mounted installations. For years, the coupling of customer-side generation coupled with excess energy exports was never specifically considered. However, some months ago this option was suggested as a way to recover the Spain’s PV sector from the current moratorium on the RES-E policy. A decree draft on on-site generation was issued, its central point being the consideration of electricity exports as delayed consumption rights. But several barriers hinder its entry into force. Unfortunately, Spain could be losing an important opportunity for encouraging PV investments while retail grid parity is being reached. This working paper analyzes the different types of PV demand-side generation from the point of view of consumer-generators and evaluates the economic and technical features of the regulation proposed in Spain and to date still pending.

description: The antiviral potential of natural polysaccharide compounds has been demonstrated, especially against enveloped viruses and members of the Herpesviridae family. Two polysaccharide fractions obtained from Stevia rebaudiana (Bertoni) leaves, that were active against Herpes simplex virus type 1 (HSV-1) were studied to investigate their mode of action. Both polysaccharides - SFW (crude faction) and SSFK (homogeneous alkaline fraction) - exerted antiviral effects on the initial stages of HSV-1 infection by inhibiting viral adsorption and penetration. When added after virus internalization, both fractions decreased plaque size. The effect of the fractions was confirmed by investigating viral glycoprotein expression. Based on the mode of action of the polysaccharides demonstrated in the present work and on their selectivity index, the polysaccharides obtained from S. rebaudiana could be an alternative treatment of infections caused by HSV-1.

description: Rhaponticum acaule (L.) DC. is a medicinal plant commonly used for the treatment of some illnesses such as gastrointestinal infections. In this work, we report the composition of different parts of this plant on phenolic compounds, their quantification, and antioxidant activity. The obtained results reported that methanolic extracts of the three parts studied revealed high phenolic contents. For flavonoid contents, the highest contents were reported in organic extracts of leaf part. In addition, results obtained from the study of the antioxidant activity showed that methanolic extract of root presented the highest activity, in DPPH• scavenging ability test with an IC50 of 0.31 ± 0.04 mg/mL and in FRAP test with an EC50 of 1.06 ± 0.02 mg/mL. The RP-HPLC-PDA analysis revealed the presence of five phenolic acids (sinapic, caffeic, chlorogenic, ferulic and syringic acids), one flavanone (naringenin), one flavonol (rutin) and vanillin.
Common Correlated Effects Estimation of Heterogeneous Dynamic Panel Data Models with Weakly Exogenous Regressors
Creators: name: Pesaran, M. Hashem
name: Chudik, Alexander
Publisher: name: Faculty of Economics
Year: 2013
Subjects: Large panels, lagged dependent variable, cross sectional dependence, coefficient heterogeneity, estimation and inference, common correlated effects, unobserved common factors

description: This paper extends the Common Correlated Effects (CCE) approach developed by Pesaran (2006) to heterogeneous panel data models with lagged dependent variable and/or weakly exogenous regressors. We show that the CCE mean group estimator continues to be valid but the following two conditions must be satisfied to deal with the dynamics: a sufficient number of lags of cross section averages must be included in individual equations of the panel, and the number of cross section averages must be at least as large as the number of unobserved common factors. We establish consistency rates, derive the asymptotic distribution, suggest using co- variates to deal with the effects of multiple unobserved common factors, and consider jackknife and recursive de-meaning bias correction procedures to mitigate the small sample time series bias. Theoretical findings are accompanied by extensive Monte Carlo experiments, which show that the proposed estimators perform well so long as the time series dimension of the panel is sufficiently large.
Radiatively Induced Neutrino Masses and Large Higgs-Neutrino Couplings in the Standard Model with Majorana Fields
Creators: name: Pilaftsis, Apostolos
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The Higgs sector of the Standard Model with one right-handed neutrino per family is systematically analyzed. In a model with intergenerational independent mixings between families, we can account for very light neutrinos acquiring Majorana masses radiatively at the first electroweak loop level. We also find that in such a scenario the Higgs coupling to the light-heavy neutrinos and to the heavy-heavy ones may be remarkably enhanced with significant implications for the production of these heavy neutrinos at high energy colliders.

description: We present our design of a compact, integrated and tunable dual-wavelength diode laser system emitting around 785 nm, which is of interest for several applications like Raman spectroscopy and the generation of THz radiation. To achieve a more compact device compared to previous GaAs based designs two etch depths are realized, leading to shallowly etched ridge waveguides in regions were optical gain is applied and deeply etched waveguides used to enable compact integrated waveguide components. The device parameters are optimized using a numerically efficient simulation tool for passive waveguides. Subsequently, the entire laser system is further analyzed applying a sophisticated traveling-wave equation based model for active devices giving access to internal intensity and carrier density distributions. It is shown that active laser simulations are crucial to deduce critical and performance limiting design aspects not accessible via an all-passive simulation.
Strong $(δ,n)$-complements for semi-stable morphisms

description: We prove boundedness of global strong $(δ,n)$-complements for generalized $ε$-log canonical pairs of Fano type. We also prove some partial results towards boundedness of local strong $(δ,n)$-complements for semi-stable morphisms. As applications, we prove an effective generalized canonical bundle formula for generalized klt pairs and an effective generalized adjunction formula for exceptional generalized log canonical centers. Moreover, we prove that the existence of strong $(δ,n)$-complements implies a conjecture due to M$^{\rm c}$Kernan concerning the singularities of the base of a Mori fiber space.

Understanding best practice regarding interruptible connections for wind generation: lessons from national and international experience
Creators: name: Anaya, Karim L.
name: Pollitt, Michael G.
Publisher: name: Faculty of Economics
Year: 2013
Subjects: distributed generation, wind generation, non-firm, smart solutions

description: The aim of this study is to explore different practices for accelerating the integration of generating facilities to the electricity network using smart solutions. Case studies from Great Britain, Ireland and Northern Ireland and the Unites States were selected. The paper assesses and compares the different Principles of Access (POA) that have been implemented in these countries, such as Last-in First-out (LIFO), Pro Rata and Market-based. The social optimality of these approaches is also discussed. The paper also evaluates how the risk (regarding curtailment and investment) is allocated between parties (distributor network operators, generators and customers). Even though the cases are diverse, important findings and lessons have been identified which may assist UK distribution network operators to address the issue of increasing the connection of distributed generation while managing efficiently and economically energy exports from generators.
Two EGARCH models and one fat tail
Creators: name: Harvey, Andrew
name: Caivano, Michele
Publisher: name: Faculty of Economics
Year: 2013
Subjects: Exchange rates; heavy tails; Hill's estimator, score; robustness; Student's t; tail index

description: We compare two EGARCH models which belong to a new class of models in which the dynamics are driven by the score of the conditional distribution of the observations. Models of this kind are called dynamic conditional score (DCS) models and their form facilitates the development of a comprehensive and relatively straightforward theory for the asymptotic distribution of the maximum likelihood estimator. The EGB2 distribution is light-tailed, but with higher kurtosis than the normal. Hence it is complementary to the fat-tailed t. The EGB2-EGARCH model gives a good fit to many exchange rate return series, prompting an investigation into the misleading conclusions liable to be drawn from tail index estimates.
Building Transmission Backbone for Highway Vehicular Networks: Framework and Analysis

description: The highway vehicular ad hoc networks, where vehicles are wirelessly inter-connected, rely on the multi-hop transmissions for end-to-end communications. This, however, is severely challenged by the unreliable wireless connections, signal attenuation and channel contentions in the dynamic vehicular environment. To overcome the network dynamics, selecting appropriate relays for end-to-end connections is important. Different from the previous efforts (\emph{e.g.}, clustering and cooperative downloading), this paper explores the existence of stable vehicles and propose building a stable multi-hop transmission backbone network in the highway vehicular ad hoc network. Our work is composed of three parts. Firstly, by analyzing the real-world vehicle traffic traces, we observe that the large-size vehicles, \emph{e.g.}, trucks, are typically stable with low variations of mobility and stable channel condition of low signal attenuation; this makes their inter-connections stable in both connection time and transmission rate. Secondly, by exploring the stable vehicles, we propose a distributed protocol to build a multi-hop backbone link for end-to-end transmissions, accordingly forming a two-tier network architecture in highway vehicular ad hoc networks. Lastly, to show the resulting data performance, we develop a queueing analysis model to evaluate the end-to-end transmission delay and throughput. Using extensive simulations, we show that the proposed transmission backbone can significantly improve the reliability of multi-hop data transmissions with higher throughput, less transmission interruptions and end-to-end delay.
