description: I'll describe a general geometric setup allowing for a generalization of Rehren duality to asymptotically anti-de Sitter spacetimes whose classical matter distribution is sufficiently well-behaved as to prevent the occurence of singularities in the sense of null geodesic incompleteness. I'll also comment on the issues involved in the reconstruction of an additive and locally covariant bulk net of observables from a corresponding boundary net in this more general situation.

description: Pellet ELM triggering is a well established scheme for decreasing the time between two successive ELM crashes below its natural value. Reliable ELM pacing has been demonstrated experimentally in several devices increasing the ELM frequency considerably. However, it was also shown that the frequency cannot be increased arbitrarily due to a so-called lag-time. During this time after a preceding natural or triggered ELM crash, neither a natural ELM crash occurs nor the triggering of an ELM crash by pellet injection is possible. For this article, pellet ELM triggering simulations are advanced beyond previous studies in two ways. Firstly, realistic ExB and diamagnetic background flows are included. And secondly, the pellet is injected at different stages of the pedestal build-up. This allows to recover the lag-time for the first time in simulations and investigate it in detail. A series of non-linear extended MHD simulations is performed to investigate the plasma dynamics resulting from an injection at different time points during the pedestal build-up. The experimentally observed lag-time is qualitatively reproduced well. In particular, a sharp transition is observed between the regime where no ELMs can be triggered and the regime where pellet injection causes an ELM crash. Via variations of pellet parameters and injection time, the two regimes are studied and compared in detail revealing pronounced differences in the non-linear dynamics. The toroidal mode spectrum is significantly broader when an ELM crash is triggered enhancing the stochasticity and therefore also the losses of thermal energy along magnetic field lines. In the heat fluxes to the divertor targets, pronounced toroidal asymmetries are observed. In case of high injection velocities leading to deep penetration, also the excitation of core modes like the $2/1$ neoclassical tearing mode is observed.

description: Gender characteristics of speech to do with prosody and linguistic style influence how a person is understood. We investigated electrophysiological correlates of these. Twenty-four people listened to sentences spoken by a female who manipulated her prosody by using a feminine and an imitated masculine voice and her linguistic style by using function words differentially associated with males and females. Event-related potentials unexpectedly showed a larger N400 elicited by imitated masculine compared to feminine prosody. A prosody by linguistic style interaction was also found in late positive components and a later window, where sentences congruent with speaker sex and gender (i.e. feminine prosody, linguistic style, and voice) were more negative going than sentences that were not. Further results showed less upper-alpha (∼10–13 Hz) event-related desynchronisation with imitated masculine compared to feminine prosody in a late time-window. These results suggest gender atypical speech affects early and reduces later semantic processing.

description: Ultracold alkali atoms provide experimentally accessible model systems for probing quantum states that manifest themselves at the macroscopic scale. Recent experimental realizations of superfluidity in dilute gases of ultracold fermionic (half-integer spin) atoms offer exciting opportunities to directly test theoretical models of related many-body fermion systems that are inaccessible to experimental manipulation, such as neutron stars and quark-gluon plasmas. However, the microscopic interactions between fermions are potentially quite complex, and experiments in ultracold gases to date cannot clearly distinguish between the qualitatively different microscopic models that have been proposed. Here, we theoretically demonstrate that optical measurements of electron spin noise -- the intrinsic, random fluctuations of spin -- can probe the entangled quantum states of ultracold fermionic atomic gases and unambiguously reveal the detailed nature of the interatomic interactions. We show that different models predict different sets of resonances in the noise spectrum, and once the correct effective interatomic interaction model is identified, the line-shapes of the spin noise can be used to constrain this model. Further, experimental measurements of spin noise in classical (Boltzmann) alkali vapors are used to estimate the expected signal magnitudes for spin noise measurements in ultracold atom systems and to show that these measurements are feasible.
In Memoriam. Professor Karl-Feliks Sauks (28.07.1915–3.11.1983)
Creators: name: Siimon, Aino
Publisher: name: MATTIMAR OÜ
Year: 2015

description: Karl-Feliks Sauks has left a deep imprint on the history of economics and on the Faculty of Economics as researcher, teaching staff, head. He received a candidate’s degree, became a professor and worked as a head of Chair for 17 years. F. Sauks spent his childhood and school-years in Tallinn and continued his studies at the University of Tartu. As a student, he worked as an assistant at the Chair of Economic History. Sauks graduated from the University of Tartu in 1940 with cum laude in public economics. Professional career in Tallinn after university was cut short (until July 1941) as an oppressive period followed: at first as a labourer at home front, later as lecturer in an Yegor’yevsk educational combine and supervisor for planned economy courses. After reevacuation, Sauks was appointed as lecturer in commercial economics at Tallinn Polytechnic Institute (Sept 1944). During this period (1949, 1950) a two-part commercial economics textbook was published, representing an important research area of Sauks. During 1951-1954 he worked as head of Chair of Commercial Economics. In 1952, he defended his thesis in Plekhanov Moscow Institute of the National Economy. A compre-hendsive work (301 p.) on Estonian commercial network had to be written in Russian. This became a second important research area for Sauks. In 1954, the Chair of Commercial Economy was transferred to Tartu State University. Sauks organised the launching of studies in Tartu, led the department of economics until 1962 and chair until 1968.
His research period (1960-1972) was abundant in terms of published work and preceded his election as professor. He began to extensively research into Estonian commerce development, his topic for doctoral dissertation. Sauks also participated in a research group studying the history of Tartu and Tallinn. This was included in anthologies much later: he as author of the parts concerning commerce history in Tallinn (1969, 1976) and Tartu (1980). It is also important to note that he supervised the laboratory of Commerce and research students. In 1972, he was appointed professor of Chair of Economics. The election was initiated by the faculty. Sauks had finished with his thesis, but the final touches would have taken time and effort. This, however, was forbidden by doctors because of the author’s poor health. Docent Sauks was worthy of the position of professor because of his research work, including translation of chapters 13-18 of Capital volume III, as an author and as founder of the Faculty of Economics. He did not receive an invitation for a professor position until 1976. As of 1979, he worked as consultant professor because of his poor health. He died on 3 November 1983.

description: Studies of non-native speech sound learning report considerable individual variability in learning new sounds and retaining them in memory. The current study tested whether individual variation in brain structure (measured using MRI) accounts for differences in learning or retention of non-native speech sounds. Fifty-seven participants were tested on identification and discrimination of difficult non-native speech sounds in the evening before training, after training, and tested again the next morning. Surface area and volume of the left superior temporal gyrus positively predicted discrimination learning, whereas surface area of the left transverse temporal gyrus negatively predicted overnight improvement of identification. Hippocampal volume as well as gyrification of bilateral transverse temporal gyri positively predicted overnight improvement of discrimination. Findings suggest that individual differences in non-native speech sound learning can be traced to differences in brain structure supporting perception, while differences in retention are linked to the structure of hippocampal regions important for memory consolidation.

description: Experiments at DA$Φ$NE-Frascati and at J-PARC are scheduled to produce $K^-$D atoms and observe their X-ray cascade down to the 1$S$ ground state (g.s.), thereby measuring its strong-interaction width and shift away from a purely Coulomb state. A width $Γ_{1S}\lesssim 1$ keV will ensure good resolution of the X-ray transitions feeding the 1$S$ g.s. Here we study the expected $K^-$D 1$S$ g.s. width from the perspective of global fits to level shifts and widths in heavier kaonic atoms across the periodic table, using $K^-$ nuclear optical potentials constructed from $\bar K N$ chiral interaction models. Special attention is paid to the subthreshold energy at which the $\bar K N$ subsystem interacts in the $K^-$D atomic g.s. Within this approach we predict strong-interaction upward level shift of close to 700 eV and width of about 1.2 to 1.3 keV for the $K^-$D atom 1$S$ g.s., in fair agreement with genuinely three-body $K^-$D atom calculations. Comparison is made with $π^-$D atom phenomenology.

It is found that the electroweak corrections can be of the same order as the SUSY-QCD corrections and interfere destructively in some region of parameter space. The full one loop correction can reach 10% in some SUGRA scenario, while in general MSSM, the one loop correction can reach 20% for large $\tanβ$ and large trilinear soft breaking terms $A_b$.

description: In this article we study a family of four-dimensional, $\mathcal{N}=2$ supergravity theories that interpolates between all the single dilaton truncations of the $\mathrm{SO}(8)$ gauged $\mathcal{N}=8$ supergravity. In this infinitely many theories characterized by two real numbers -- the interpolation parameter and the dyonic "angle" of the gauging -- we construct non-extremal electrically or magnetically charged black hole solutions and their supersymmetric limits. All the supersymmetric black holes have non-singular horizons with spherical, hyperbolic or planar topology. Some of these supersymmetric and non-extremal black holes are new examples in the $\mathcal{N}=8$ theory that do not belong to the STU model. We compute the asymptotic charges, thermodynamics and boundary conditions of these black holes and show that all of them, except one, introduce a triple trace deformation in the dual theory.

description: Photochromism in single nitrogen-vacancy optical centers in diamond is demonstrated. Time-resolved optical spectroscopy shows that intense irradiation at 514 nm switches the nitrogen-vacancy defects to the negative form. This defect state relaxes back to the neutral form under dark conditions. Temporal anticorrelation of photons emitted by the different charge states of the optical center unambiguously indicates that the nitrogen-vacancy defect accounts for both 575 nm and 638 nm emission bands. Possible mechanism of photochromism involving nitrogen donors is discussed.

description: The effects of gravitomagnetic force on plasma oscillations are investigated using the kinetic theory of homogeneous electrically neutral plasma in the absence of external electric or magnetic field. The random phase assumption is employed neglecting the thermal motion of the electrons with respect to a fixed ion background. It is found that the gravitomagnetic force reduces the characteristic frequency of the plasma thus enhancing the refractive index of the medium. The estimates for the predicted effects are given for a typical white dwarf, pulsar, and neutron star.

description: Braneworld inflation on the resolved warped deformed conifold is represented by the dynamics of a D3-brane probe with the world volume of a brane spanning the large dimensions of the observable Universe. This model was recently proposed as a string theory candidate for slow-roll inflationary cosmology in hep-th/0511254. During inflation, the scalar curvature of the Universe is determined by the Hubble scale. We argue that taking into account the curvature of the inflationary Universe renders dynamics of the D3-brane fast-roll deep inside the warped throat.

description: It has been shown that a single-domain magnetic nanoparticle can be effectively switched by a linear down-chirp microwave field pulse (DCMWP) in zero temperature limit. However, finite temperature is ubiquitous in practice. Here, we study the effect of finite temperature on the DCMWP-induced magnetization reversal based on the stochastic Landau-Lifshitz-Gilbert equation. It is found that any one of the three controlling parameters of a DCMWP, i.e. the amplitude, chirp rate, or initial frequency, decreases with increasing temperature while the other two are fixed. The maximal temperature at which the reversal can happen increases with enlarging the system size. These phenomena are related to the facts that the energy barrier induced by anisotropy increases with the system volume, and the effective magnetization decreases with temperature. We also provide a set of optimal parameters for practical realization of our proposal. These findings may provide a way to realize low-cost and fast magnetization reversal with a wide operating temperature.
Modeling combination of question order effect, response replicability effect, and QQ-equality with quantum instruments

description: We continue to analyze basic constraints on the human decision making from the viewpoint of quantum measurement theory (QMT). As it has been found, the conventional QMT based on the projection postulate cannot account for the combination of the question order effect (QOE) and the response replicability effect (RRE). This was alarming finding for quantum-like modeling of decision making. Recently, it was shown that this difficulty can be resolved by using of the general QMT based on quantum instruments. In the present paper we analyse the problem of the combination of QOE, RRE, and the well-known QQ-equality (QQE). This equality was derived by Busemeyer and Wang and it was shown (in a joint paper with Solloway and Shiffrin) that statistical data from many social opinion polls satisfy it. Here we construct quantum instruments satisfying QOE, RRE and QQE. The general features of our approach are formalized with postulates that generalize (the Wang-Busemeyer) postulates for quantum-like modeling of decision making. Moreover, we show that our model closely reproduces the statistics of the well-known Clinton-Gore Poll data with a prior belief state independent of the question order. This model successfully corrects for the order effect in the data to determine the "genuine" distribution of the opinions in the Poll. The paper also provides an accessible introduction to the theory of quantum instruments - the most general mathematical framework for quantum measurements.

description: Australian retail and farming organisations act as major collaborating partners for Australian food rescue organisations by donating surplus edible food waste to Australian food rescue organisations. Previous studies indicate the importance of food waste data of the food donors for rescue efforts of food rescue organisations. Despite its importance, this study finds a gap in the literature which examines food waste reporting of Australian retail and farming organisations in the context of food rescue efforts. This study aims to investigate the importance of food waste reporting for collaboration between Australian retail farming and Australian food rescue organisations. To achieve this aim, firstly this study conducted a content analysis of published reports of Australian retail, farming, and food rescue organisations to examine how these organisations report their food waste management practices. Secondly, this study conducted semi-structured interviews with Australian retail, farming, and food rescue organisations to investigate how food waste reporting can be used to overcome collaboration challenges between Australian retail and farming organisations and Australian food rescue organisations. This study used qualitative research methods due to the exploratory nature of the research.
This study found that Australian retail and farming organisations do not report important food waste data such as total food waste, edible food waste and disposed of food waste in their published reports. This study further found that food rescue organisations highly depend on the food waste data of their donors for planning and forecasting their food rescue efforts, however, retail and farming organisations do not capture food waste data within their organisations due to the high labour cost associated with food donation work. This study recommends policymakers provide tax benefits for food donors and introduce food waste reporting guidelines to improve the food waste reporting of retail and farming organisations. This study further recommends retail and farming organisations increase food waste data capturing metrics to represent the quality, value and consistency of food waste, and increase the availability of food waste reports via social media platforms to increase public awareness about food waste. The findings of this research can be used by Australian retail and farming organisations and food rescue organisations to strengthen their collaborative partnerships by improving food waste reporting. Further research is needed to investigate food waste data recoding at Australian retail and farming organisations and develop food waste reporting guidelines for Australian retail and farming organisations.

description: Highway locations having an abnormal history of accidents should be identifiable in some way. Average and critical accident numbers and rates must be known for similar locations. Averages have been determined previously for rural highways, but it is necessary to update those numbers and to determine rates for urban areas. A detailed picture of traffic accidents in Kentucky in 1978 is presented.  Average rates in terms of accidents per 100 million vehicle-miles (160 million vehicle-kilometers) were calculated for various classifications of rural and urban highways. Also, average rates in terms of accidents per million vehicles were determined for 0.3-mile (0.48-km) highway spots. Using these averages, critical accident rates were determined as a function of volume and section length and as a function of volume only for spots. The average and critical number of total accidents and EPDO accidents were calculated for each highway type. Rates were calculated by region of the state and as a function of several variables listed on the statewide mileage file. Rates by light condition and pavement surface condition were also determined. Rate calculations included about one-half of the accidents reported in 1978. Separate analyses of all accidents reported and of all fatal accidents are included.

description: In this work we study modifications of the spectrum of fermions interacting with kinklike structures in two-dimensional spacetime. We consider the Yukawa coupling between fermions and scalar fields that engender nontrivial internal structure and investigate how the fermion spectra change in terms of the parameters that control the kinklike configuration and the Yukawa coupling. We consider models that allow the internal structure of the kinklike solution to respond to the presence of a geometrical constriction, and show the fermion spectra may also appear directly affected by the constriction. The main results are of current interest and may be used to propose the construction of electronic devices capable of engendering new effects at the nanometric scale.

description: We construct a Topological Quantum Field Theory (in the sense of Atiyah) associated to the universal finite-type invariant of 3-dimensional manifolds, as a functor from the category of 3-dimensional manifolds with parametrized boundary, satisfying some additional conditions, to an algebraic-combinatorial category. It is built together with its truncations with respect to a natural grading, and we prove that these TQFTs are non-degenerate and anomaly-free. The TQFT(s) induce(s) a (series of) representation(s) of a subgroup ${\cal L}_g$ of the Mapping Class Group that contains the Torelli group. The N=1 truncation produces a TQFT for the Casson-Walker-Lescop invariant.

Subjects: subject: Transportation Engineering

description: This report deals with the identification and rehabilitation of high-risk drivers. Methods used to identify negligent drivers were examined. Kentucky's point system was compared to those tn other states. The consequences of drivers attending driverimprovement clinics were studied by analyzing driving records.  The analysis showed that accident involvement was directly related to the accumulation of penalty points and number of violations. Definite relationships were found between several specific types of violations and accidents.  A very significant improvement in driving records was noted for those drivers who completed a driver-improvement clinic; however, a similar improvement occurred for drivers eligible for the clinic but who did not attend. The driving record of persons completing a clinic remained poor compared to all other drivers. When a longer period after attending the clinic was considered (three to four years), an improvement in driving records was found for drivers who attended the driver-improvement clinic compared to those who did not attend the clinic.  A revised point system was recommended for Kentucky. The revisions included changes in the number of points assessed for various violations and the types of violations to be included. The recommendations were based on an analysis of point systems used in other states and an analysis of driving records contained in the master driver license file.

description: Understanding and engineering the self-assembly of soft colloidal particles (microgels) at liquid-liquid interfaces is broadening their use in colloidal lithography. Here, we present a new route to assemble rectangular lattices of microgels at near zero surface pressure relying on the balance between attractive quadrupolar capillary interactions and steric repulsion among the particles at water/oil interfaces. These self-assembled rectangular lattices are obtained for a broad range of particles and, after deposition, can be used as lithography masks to obtain regular arrays of vertically aligned nanowires via wet and dry etching processes.

In the second Fermi Pulsar Catalogue, 117 new gamma-ray pulsars have been reported based on three years of data collected by the Large Area Telescope on the Fermi satellite, providing a wealth of information such as the peak separation~$Δ$ of the gamma-ray pulsations and the radio lag~$δ$ between the gamma-ray and radio pulses. We selected several radio-loud millisecond gamma-ray pulsars with period~$P$ in the range 2-6~ms and showing a double peak in their gamma-ray profiles. We attempted to constrain the geometry of their magnetosphere, namely the magnetic axis and line-of-sight inclination angles for each of these systems. We applied a force-free dipole magnetosphere from the stellar surface up to the striped wind region -- well outside the light cylinder -- to fit the observed pulse profiles in gamma-rays, consistently with their phase alignment with the radio profile. In deciding whether a fitted curve is reasonable or not, we employed a least-square method to compare the observed gamma-ray intensity with that found from our model, emphasising the amplitude of the gamma-ray peaks, their separation, and the phase lag between radio and gamma-ray peaks. We obtained the best fits and reasonable parameters in agreement with observations for ten millisecond pulsars. Eventually, we constrained the geometry of each pulsar described by the magnetic inclination~$α$ and the light-of-sight inclination~$ζ$. We found that both angles are larger than approximately~$45^{\rm o}$.

description: We investigate empirical scaling relations between the thermal Sunyaev-Zeldovich effect (SZE) and cluster mass in simulated clusters of galaxies. The simulated clusters have been compiled from four different samples that differ only in their assumed baryonic physics. We show that the strength of the thermal SZE integrated over a significant fraction of the virialized region of the clusters is relatively insensitive to the detailed heating and cooling processes in the cores of clusters by demonstrating that the derived scaling relations are nearly identical between the four cluster samples considered. For our synthetic images, the central Comptonization parameter shows significant boosting during transient merging events, but the integrated SZE appears to be relatively insensitive to these events. Most importantly, the integrated SZE closely tracks the underlying cluster mass. Observations through the thermal SZE allow a strikingly accurate mass estimation from relatively simple measurements that do not require either parametric modeling or geometric deprojection and thus avoid assumptions regarding the physics of the ICM or the symmetry of the cluster. This result offers significant promise for precision cosmology using clusters of galaxies.

description: A few questions related to white dwarfs' physics is posed. It seems that the modified gravity framework can be a good starting point to provide alternative explanations to cooling processes, their age determination, and Chandrasekhar mass limits. Moreover, we have also obtained the Chandrasekhar limit coming from Palatini $f(\mathcal{R})$ gravity provided by a simple Lane-Emden model.

description: For a non-cooperative differential game, the value functions of the various players satisfy a system of Hamilton-Jacobi equations. In the present paper, we consider a class of infinite-horizon games with nonlinear costs exponentially discounted in time. By the analysis of the value functions, we establish the existence of Nash equilibrium solutions in feedback form and provide results and counterexamples on their uniqueness and stability.

Pole skipping and chaos in anisotropic plasma: a holographic study

description: Recently, a direct signature of chaos in many body system has been realized from the energy density retarded Green's function using the phenomenon of `pole skipping'. Moreover, special locations in the complex frequency and momentum plane are found, known as the pole skipping points such that the retarded Green's function can not be defined uniquely there. In this paper, we compute the correction/shift to the pole skipping points due to a spatial anisotropy in a holographic system by performing near horizon analysis of EOMs involving different bulk field perturbations, namely the scalar, the axion and the metric field. For vector and scalar modes of metric perturbations we construct the gauge invariant variable in order to obtain the master equation. Two separate cases for every bulk field EOMs is considered with the fluctuation propagating parallel and perpendicular to the direction of anisotropy. We compute the dispersion relation for momentum diffusion along the transverse direction in the shear channel and show that it passes through the first three successive pole skipping points. The pole skipping phenomenon in the sound channel is found to occur in the upper half plane such that the parameters Lyapunov exponent $λ_{L}$ and the butterfly velocity $v_{B}$ are explicitly obtained thus establishing the connection with many body chaos.

description: Quantum mechanics permits an entity, such as an atom, to exist in a superposition of multiple states simultaneously. Quantum information processing (QIP) harnesses this profound phenomenon to manipulate information in radically new ways. A fundamental challenge in all QIP technologies is the corruption of superposition in a quantum bit (qubit) through interaction with its environment. Quantum bang-bang control provides a solution by repeatedly applying `kicks' to a qubit, thus disrupting an environmental interaction. However, the speed and precision required for the kick operations has presented an obstacle to experimental realization. Here we demonstrate a phase gate of unprecedented speed on a nuclear spin qubit in a fullerene molecule (N@C60), and use it to bang-bang decouple the qubit from a strong environmental interaction. We can thus trap the qubit in closed cycles on the Bloch sphere, or lock it in a given state for an arbitrary period. Our procedure uses operations on a second qubit, an electron spin, in order to generate an arbitrary phase on the nuclear qubit. We anticipate the approach will be vital for QIP technologies, especially at the molecular scale where other strategies, such as electrode switching, are unfeasible.

description: A classically scale-invariant scalar singlet can be a MeV-scale dark matter, with a feeble Higgs portal coupling at $\mathcal{O}(10^{-10})$. Besides, an $\mathcal{O}(0.1)$ self-interaction coupling could further serve to alleviate the small-scale problems in the Universe. We show that, such a dark matter candidate can naturally arise in the warped extra dimension, with the huge span of parameter space predicted well within $\mathcal{O}(1)$ fundamental parameters.

description: We introduce a new braid-theoretic framework with which to understand the Legendrian and transversal classification of knots, namely a Legendrian Markov Theorem without Stabilization which induces an associated transversal Markov Theorem without Stabilization. We establish the existence of a nontrivial knot-type specific Legendrian and transversal MTWS by enhancing the Legendrian mountain range for the (2,3)-cable of a (2,3)-torus knot provided by Etnyre and Honda, and showing that elementary negative flypes allow us to move toward maximal tb value without having to use Legendrian stabilization. In doing so we obtain new ways to visualize convex tori and Legendrian divides and rulings, using tilings and braided rectangular diagrams.

description: Aims: We investigate the orbital and phase space properties of loss cone stars that interact strongly with a hard, high-redshift binary supermassive black hole (SMBH) system formed in a cosmological scenario. Methods: We use a novel hybrid integration approach that combines the direct N-body code $φ$-GRAPE with ETICS, a collisionless code that employs the self-consistent field method for force calculation. The hybrid approach shows considerable speed-up over direct summation for particle numbers $> 10^6$, while retaining accuracy of direct N-body for a subset of particles. During the SMBH binary evolution we monitor individual stellar interactions with the binary in order to identify stars that noticeably contribute to the SMBH binary hardening. Results: We successfully identify and analyze in detail the properties of stars that extract energy from the binary. We find that the summed energy changes seen in these stars match very well with the overall binary energy change, demonstrating that stellar interactions are the primary drivers of SMBH binary hardening in triaxial, gas-poor systems. The slight triaxiality of our system results in efficient loss cone refilling, avoiding the final parsec problem. We distinguish three different populations of interactions based on their apocenter. We find a clear prevalence of interactions co-rotating with the binary. Nevertheless, retrograde interactions are the most energetic, contributing only slightly less than the prograde population to the overall energy exchange. The most energetic interactions are also likely to result in a change of sign in the angular momentum of the star. We estimate the merger timescale of the binary to be $\approx 20$ $\mathrm{Myr}$, a value larger by a factor of two than the timescale reported in a previous study.
