description: The problem of unicity and reidentifiability of records in large-scale databases has been studied in different contexts and approaches, with focus on preserving privacy or matching records from different data sources. With an increasing number of service providers nowadays routinely collecting location traces of their users on unprecedented scales, there is a pronounced interest in the possibility of matching records and datasets based on spatial trajectories. Extending previous work on reidentifiability of spatial data and trajectory matching, we present the first large-scale analysis of user matchability in real mobility datasets on realistic scales, i.e. among two datasets that consist of several million people's mobility traces, coming from a mobile network operator and transportation smart card usage. We extract the relevant statistical properties which influence the matching process and analyze their impact on the matchability of users. We show that for individuals with typical activity in the transportation system (those making 3-4 trips per day on average), a matching algorithm based on the co-occurrence of their activities is expected to achieve a 16.8% success only after a one-week long observation of their mobility traces, and over 55% after four weeks. We show that the main determinant of matchability is the expected number of co-occurring records in the two datasets. Finally, we discuss different scenarios in terms of data collection frequency and give estimates of matchability over time. We show that with higher frequency data collection becoming more common, we can expect much higher success rates in even shorter intervals.

description: Detailed studies of weak charm decays fill an important {\em future} role in high energy physics. Chief among them are: (i) validating the theoretical control achieved over hadronization as a worthwhile goal in its own right; (ii) calibrating our tools to saturate the discovery potential for New Physics in B decays; (iii) searching for New Physics in charm decays through hypothesis-generating research. The most promising area for the last item is a comprehensive study of \cp violation. Since we need a new \cp paradigm to implement baryogenesis, this is not an idle goal. Charm decays provide opportunities unique among {\em up-}type quarks. While items (i) and (ii) will be addressed in a meaningful way and hopefully completed in the next few years, item (iii) will presumably require statistics that can be accumulated only by LHCb and a Super-B factory.

description: We present subarcsecond-resolution mid-infrared images of the debris disk surrounding the 230 Myr- old A star Zeta Lep. Our data obtained with T-ReCS at Gemini South show the source to be unresolved at 10.4 microns but clearly extended at 18.3 microns. Quadratic subtraction of the PSF profile from that of Zeta Lep implies a characteristic radius for the dust disk of 3 AU, which is comparable in size to our solar system's asteroid belt. Simple models suggest that the 18 micron flux is well approximated by two contiguous annuli of mid-infrared-emitting dust from 2-4 and 4-8 AU with a 3:1 flux ratio for the annuli, respectively. We consider two scenarios for the collisions that must be resupplying the dust population: (1) continuous "steady state" grinding of planetesimals, and (2) an isolated cataclysmic collision. We determine that radiation pressure and subsequent collisions are the dominant determinants of the disk morphology in either case, and that Poynting-Robertson drag is comparatively insignificant.

description: Space out of a topological defect of the Abrikosov-Nielsen-Olesen vortex type is locally flat but non-Euclidean. If a spinor field is quantized in such a space, then a variety of quantum effects is induced in the vacuum. Basing on the continuum model for long-wavelength electronic excitations, originating in the tight-binding approximation for the nearest neighbor interaction of atoms in the crystal lattice, we consider quantum ground state effects in monolayer structures warped into nanocones by a disclination; the nonzero size of the disclination is taken into account, and a boundary condition at the edge of the disclination is chosen to ensure self-adjointness of the Dirac-Weyl Hamiltonian operator. In the case of carbon nanocones, we find circumstances when the quantum ground state effects are independent of the boundary parameter and the disclination size.

description: My great-grandfather Józef Szybkowski, born in the village of Daszyna, Łódź province, Poland in 1914, was called up to the army in 1938 and was assigned to a machine-gun company in the 37th Infantry Regiment, based in the city of Kutno. During the German invasion of September 1939, his regiment participated in the Battle of the Bzura River (otherwise known as the Battle of Kutno). The regiment suffered heavy losses and on the 18 September my great-grandfather was among some of the last survivors that surrendered to the Germans in the village of Iłów. Afterwards, he was sent to Germany and incarcerated at Stalag XA in Schleswig-Holstein until 1941, when he was assigned to a working party on a farm in Handewittfeld. On this farm, he was, according to his testimony, treated quite well by the German family that he worked for. In 1943, he met my great-grandmother Antonia Jeremenko, a young Ukrainian deported from her home to work on the farm, and struck up a relationship. In 1944, their first child was born, and, shortly before the end of the war, they were transferred to a holding camp in the city of Flensburg, where they were liberated by British forces in 1945. Soon after, they were married at the local registry office. Unwilling to return to Communist-controlled Poland, Józef served with the British Army of the Rhine until 1950, when he and the family were re-settled to Victoria, Australia where he found work as a farmhand, eventually settling in the town of Koo Wee Rup, where he passed away in 1990.

description: Unitarity along with precision measurements of sin2β, V_{us} and V_{cb} allows one to find a lower bound V_{ub}\geq 0.0035 which, on using the recently measured angle αof the unitarity triangle, translates to V_{ub}= 0.0035\pm 0.0002. This precise value, stable for a good deal of changes in α, along with CP violating phase δfound from unitarity allows the construction of a `precise' CKM matrix. The above unitarity based value of V_{ub} is in agreement with the latest exclusive value used as input by UTfit, CKMfitter, HFAG, however underlines the so called `tension' faced by the latest inclusive V_{ub}=0.00449 \pm 0.00033. Further, using this inclusive value of V_{ub} along with the latest sin2β, one finds δ=23 ^{\rm o}- 39 ^{\rm o}, again in conflict with δmeasured in B-decays. The calculated ranges of the elements of the CKM matrix are in excellent agreement with those obtained recently by UTfit, CKMfitter and HFAG. Also, the ratio \frac{V_{ts}}{V_{td}} is in agreement with its latest measured value, whereas there is some disagreement between the `measured' and the calculated V_{td} values.

description: Exon junction complex (EJC) assembles after splicing at specific positions upstream of exon-exon junctions in mRNAs of all higher eukaryotes, affecting major regulatory events. In mammalian cell cytoplasm, EJC is essential for efficient RNA surveillance, while in Drosophila, EJC is essential for localization of oskar mRNA. Here we developed a method for isolation of protein complexes and associated RNA targets (ipaRt) to explore the EJC RNA-binding landscape in a transcriptome-wide manner in adult Drosophila. We find the EJC at canonical positions, preferably on mRNAs from genes comprising multiple splice sites and long introns. Moreover, EJC occupancy is highest at junctions adjacent to strong splice sites, CG-rich hexamers, and RNA structures. Highly occupied mRNAs tend to be maternally localized and derive from genes involved in differentiation or development. These modalities, which have not been reported in mammals, specify EJC assembly on a biologically coherent set of transcripts in Drosophila.

description: Ultrawideband (UWB) technology offers tremendous benefits. It enables new applications, and makes other valuable applications more cost-effective than was previously possible. However, this technology creates novel challenges f o r regulators. UWB devices share spectrum with existing licensed systems, potentially causing interference. Moreover, some UWB applications raise serious privacy concerns. This submission proposes an alternative spectrum management approach f o r UWB devices that will encourage deployment while managing spectral interference and privacy abuses. Under this approach, the Federal Communication Commission (FCC) would distribute permits to manufacture or import devices, instead of the more traditional approach of distributing licenses to use the devices at a given location. This would allow the FCC to monitor, and if necessary, regulate the number and type of UWB devices deployed, without placing onerous restrictions on users.

description: Recent progress in realistic simulations of solar convection have given us an unprecedented opportunity to evaluate the robustness of solar interior structures and dynamics obtained by methods of local helioseismology. We present results of testing the time-distance method using realistic simulations. By computing acoustic wave propagation time and distance relations for different depths of the simulated data, we confirm that acoustic waves propagate into the interior and then turn back to the photosphere. This demonstrates that in the numerical simulations properties of acoustic waves (p-modes) are similar to the solar conditions, and that these properties can be analyzed by the time-distance technique. For the surface gravity waves (f-mode), we calculate perturbations of their travel times, caused by localized downdrafts, and demonstrate that the spatial pattern of these perturbations (representing so-called sensitivity kernels) is similar to the patterns obtained from the real Sun, displaying characteristic hyperbolic structures. We then test the time-distance measurements and inversions by calculating acoustic travel times from a sequence of vertical velocities at the photosphere of the simulated data, and inferring a mean 3D flow fields by performing inversion based on the ray approximation. The inverted horizontal flow fields agree very well with the simulated data in subsurface areas up to 3 Mm deep, but differ in deeper areas. Due to the cross-talk effects between the horizontal divergence and downward flows, the inverted vertical velocities are significantly different from the mean convection velocities of the simulation dataset.

12.1 Preservation of Enhanced Publications

Publisher: name: Zenodo
Year: 2015
Subjects: digital, publications, libraries, preservation

description: For several years now the concept of ‘enhanced publications’, here understood as ‘a digital object in context’, is an identified phenomenon, especially from a theoretical point of view. One of the strong advocates of getting a grip on this kind of material was the Driver project, resulting in a conceptual model. But the developments around a digital object with links to other objects are continuing rapidly. The boundaries of what is a publication in the traditional sense becomes fluid. Data, websites, movies, all can become essential as context for a publication. These elements are not necessary preserved in one place. This poses a challenge for organisations that traditionally want to preserve such material and give access to the whole set of related information. Either by mandate (national library and archive) or because it is part of their responsibilities (university libraries, data centres, etc.) In this presentation we will describe the results of the Enhanced Publications project, carried out by members of the Dutch National Coalition of Digital Preservation (NCDD). Starting with the use case of the digital academic thesis, an overview was created of organisations that are involved in the preservation of the thesis itself and its context, like related sources and data sets. This overview helped to identify responsibilities for and risks for preserving the context. As it turned out that more organisations than expected were involved, coordination in digital preservation is needed. To achieve this, a set of recommendations will help to implement necessary measures. The results of the (rather straightforward) case of the academic thesis will feed into further studies of more complicated cases of digital objects in context, that will be preserved for long-term access by Dutch organisations. Barbara Sierman MA is Digital Preservation Manager in the Research Department of the National Library of the Netherlands. She studied Dutch and was library consultant at PICA (now OCLC). After years as an IT consultant at Cap Gemini, she joined the KB in 2005. She is involved in the development of the ISO standards 16363 Audit and Certification of Trustworthy Digital Repositories and ISO 161919 Requirements for bodies providing audit and certification of candidate trustworthy digital repositories. In the SCAPE project she was responsible for the creation of the Catalogue of Preservation Policy Elements. She regularly blogs on digitalpreservation.nl/seeds.

description: Small satellites and autonomous vehicles have greatly evolved in the last few decades. Hundreds of small satellites have been launched with increasing functionalities, in the last few years. Likewise, numerous autonomous vehicles have been built, with decreasing costs and form-factor payloads. Here we focus on combining these two multifaceted assets in an incremental way, with an ultimate goal of alleviating the logistical expenses in remote oceanographic operations. The first goal is to create a highly reliable and constantly available communication link for a network of autonomous vehicles, taking advantage of the small satellite lower cost, with respect to conventional spacecraft, and its higher flexibility. We have developed a test platform as a proving ground for this network, by integrating a satellite software defined radio on an unmanned air vehicle, creating a system of systems, and several tests have been run successfully, over land. As soon as the satellite is fully operational, we will start to move towards a cooperative network of autonomous vehicles and small satellites, with application in maritime operations, both \textit{in-situ} and remote sensing.

description: In early 1944 Horrocks was desperate to put a staff together for XXX Corps in time for the invasion. All his friends were already spoken for and he was reduced to those officers who had been left, for good or bad reasons, behind. One of these was a Commandant of a POW camp in Cheshire. He made it known that he would like to join Horrocks and Horrocks agreed to visit.On the appointed day, the Camp Commandant and all his staff paraded at the front gate and waited. And waited. And a sergeant came and told the Commandant that er, General Horrocks had been and gone."Gone?" "Yes, sir, came in through the back gate, went straight to the prisoners' mess, sir. Then he left."Horrocks had opened a salt cellar and found no salt.Horrocks prized attention to detail highly. He needed staff who could get this done. He got a plan of the camp, noted the position of the canteen, came, checked and left. This shows a great level of organisation, research and planning, and tells me more about him than the Wiki article.My Dad was a deputy Camp Commandant from a nearby camp. He and his brother Hugh (who just happened to be Camp Commandant) had been invited down to "make up the numbers."

description: Motivated by the gluon condensate in QCD we study the perturbative expansion of a gauge theory in the presence of gauge bosons of vanishing momentum, in the specific case of an abelian theory. The background is characterised by a dimensionful parameter $Λ$ affecting only the on-shell prescription of the free (abelian) gluon propagator. When summed to all orders in $gΛ$ the modification is equivalent to evaluating standard Green functions in a pure gauge field with an imaginary gauge parameter $\propto Λ$. We show how to calculate the corresponding dressed Green functions, which are Poincare and gauge covariant. We evaluate the expressions for the dressed quark and $q \bar q$ propagators, imposing as boundary condition that they approach the standard perturbative form in the short-distance limit ($|p^2|\to\infty$). The on-shell ($p^2=m^2$) pole of the free quark propagator is removed for any $Λ> 0$, and replaced by a discontinuity which vanishes exponentially with $p^2$. The dressing introduces an effective interaction between quarks and antiquarks which is enhanced at low relative 3-momentum. Further study should allow to identify the (bound) eigenstates of propagation and determine whether they define a unitary S-matrix. When the quark mass is zero there is a euclidean propagator solution which breaks chiral symmetry spontaneously. We study some aspects of the massless pion contribution to axial vector correlators and derive the $πq \bar q$ form factor.

description: In this paper, we report mean-field and effective-field renormalization group calculations on the isotropic Heisenberg antiferromagnetic model under a longitudinal magnetic field. As is already known, these methods, denoted by MFRG and EFRG, are based on the comparison of two clusters of different sizes, each of them trying to mimic certain Bravais lattice. Our attention has been on the obtantion of the critical frontier in the plane of temperature versus magnetic field, for the simple cubic and the body-centered cubic lattices. We used clusters with $N=1,2,4$ spins so as to implement MFRG-12, EFRG-12 and EFRG-24 numerical equations. Consequently, the resulting frontier lines show that EFRG approach overcomes the MFRG problems when clusters of larger sizes are considered.

description: We investigate the conditions for the presence of a magnetically inactive dead zone in protostellar disks, using 3-D shearing-box MHD calculations including vertical stratification, Ohmic resistivity and time-dependent ionization chemistry. Activity driven by the magnetorotational instability fills the whole thickness of the disk at 5 AU, provided cosmic ray ionization is present, small grains are absent and the gas-phase metal abundance is sufficiently high. At 1 AU the larger column density of 1700 g/cm^2 means the midplane is shielded from ionizing particles and remains magnetorotationally stable even under the most favorable conditions considered. Nevertheless the dead zone is effectively eliminated. Turbulence mixes free charges into the interior as they recombine, leading to a slight coupling of the midplane gas to the magnetic fields. Weak, large-scale radial fields diffuse to the midplane where they are sheared out to produce stronger azimuthal fields. The resulting midplane accretion stresses are just a few times less than in the surface layers on average.

description: I was born at the end of 1934 (31 December), my memories only start when I was five years old. My father, when war broke out, was only 24, but married personnel were not called up until 1942 at this time.Our family was living in my grandfather's tithed cottage in Newton Harcourt, Leicestershire. He unfortunately died, so my mother and I had to move from the cottage. My father was in the REME at Corsham, Wiltshire where he was employed by the army as a painter in the REME workshops in the Box tunnels. He fortunately was informed by the army that in view of his personal circumstances he would hopefully spend the rest of the war in this situation. Consequently he managed to arrange an employment for my mother as a housekeeper in Corsham, so that Mother and I could move and live nearby to Father, who was living in barracks. This arrangement continued until the end of hostilities, after which the family all moved to Wigston in Leicestershire.

description: We study sharpened forms of the concentration of measure phenomenon typically centered at stochastic expansions of order $d-1$ for any $d \in \mathbb{N}$. The bounds are based on $d$-th order derivatives or difference operators. In particular, we consider deviations of functions of independent random variables and differentiable functions over probability measures satisfying a logarithmic Sobolev inequality, and functions on the unit sphere. Applications include concentration inequalities for $U$-statistics as well as for classes of symmetric functions via polynomial approximations on the sphere (Edgeworth-type expansions).

description: Images obtained with the ESO VLT and FORS1 in [O III] 5007 on- and off-band as well as r_Gunn filters are analyzed to search for Planetary Nebula (PN) candidates in the dwarf irregular NGC 3109. In the continuum-subtracted [O III] 5007 on-band images, a large number of emission-line regions were detected. We describe the criteria employed in order to distinguish PN candidates from compact HII regions, finding that the sizes and the properties of the ionizing stars are the most unambiguous discriminators for separating the two classes. Based upon these criteria, we have found 20 PN candidates for which we present coordinates, nebular [O III] fluxes, and stellar magnitudes. The cumulative luminosity function for these PNe is discussed. A catalog of HII regions listing coordinates, nebular [O III] fluxes, stellar magnitudes and other characteristics is also presented. We find that HII regions are rather concentrated towards the disk of the galaxy, while PNe are found also above and below this structure, consistent with their belonging to an older stellar population.

A fast and accurate method for perturbative resummation of transverse momentum-dependent observables

description: We propose a novel strategy for the perturbative resummation of transverse momentum-dependent (TMD) observables, using the $q_T$ spectra of gauge bosons ($γ^*$, Higgs) in $pp$ collisions in the regime of low (but perturbative) transverse momentum $q_T$ as a specific example. First we introduce a scheme to choose the factorization scale for virtuality in momentum space instead of in impact parameter space, allowing us to avoid integrating over (or cutting off) a Landau pole in the inverse Fourier transform of the latter to the former. The factorization scale for rapidity is still chosen as a function of impact parameter $b$, but in such a way designed to obtain a Gaussian form (in $\ln b$) for the exponentiated rapidity evolution kernel, guaranteeing convergence of the $b$ integral. We then apply this scheme to obtain the $q_T$ spectra for Drell-Yan and Higgs production at NNLL accuracy. In addition, using this scheme we are able to obtain a fast semi-analytic formula for the perturbative resummed cross sections in momentum space: analytic in its dependence on all physical variables at each order of logarithmic accuracy, up to a numerical expansion for the pure mathematical Bessel function in the inverse Fourier transform that needs to be performed just once for all observables and kinematics, to any desired accuracy.

description: Dissipative phase transitions in quantum systems have been largely studied under the so-called Markovian approximation, where the environments to which the systems are coupled are memoryless. Here, we present a generalization of the spectral theory of dissipative phase transitions to non-Markovian systems, encompassing a much broader class of quantum materials and experiments and opening many possibilities for non-Markovian engineering of matter phases such as, as explored in the companion Letter [Debecker et. al., Phys. Rev. Lett. 133, 140403 (2024)], reshaping of phase boundaries and triggering of phase transitions. We first prove several statements about the connections between the spectrum of the generator of the non-Markovian dynamics of general systems and dissipative phase transitions. Then, as a benchmark, we show that our framework can capture all the expected signatures of the superradiant phase transition appearing in a challenging $U(1)$-symmetric two-mode Dicke model from a reduced description of the dynamics of the atoms only, a task for which all other methods have failed so far.

description: We consider superconducting circuits for the purpose of simulating the spin-boson model. The spin-boson model consists of a single two-level system coupled to bosonic modes. In most cases, the model is considered in a limit where the bosonic modes are sufficiently dense to form a continuous spectral bath. A very well known case is the ohmic bath, where the density of states grows linearly with the frequency. In the limit of weak coupling or large temperature, this problem can be solved numerically. If the coupling is strong, the bosonic modes can become sufficiently excited to make a classical simulation impossible. Here, we discuss how a quantum simulation of this problem can be performed by coupling a superconducting qubit to a set of microwave resonators. We demonstrate a possible implementation of a continuous spectral bath with individual bath resonators coupling strongly to the qubit. Applying a microwave drive scheme potentially allows us to access the strong-coupling regime of the spin-boson model. We discuss how the resulting spin relaxation dynamics with different initialization conditions can be probed by standard qubit-readout techniques from circuit quantum electrodynamics.

description: This study involved twenty structured interviews with researchers, research and development (R&D) managers, and other experts in fossil-energy technologies from government, academia, and the private sector. The intent was to gain a deeper understanding of the kinds of developments that would constitute a radical innovation in fossil-energy technology and its potential impact in the associated environmental control domain. The meanings of related terms often used to describe innovations—such as breakthrough, discontinuity or disruptive—also were explored in these interviews.

description: The phenomenon of technological learning has been observed across a wide spectrum of energy and environmental technologies. Quantitative modeling of experience curves has become an increasingly common method of representing endogenous technical change in long-term integrated assessment models used for energy and environmental policy analysis. However, many issues remain to be addressed in the use of experience curves to quantify long-term cost trends of energy technologies. This paper highlights and critically reviews some of the major sources of uncertainty and their implications to model outcomes. It draws on recent empirical literature, as well as on new data characterizing historical cost trends in the early deployment of three environmental technologies especially relevant to energy systems. Our findings indicate the need for a more thorough and systematic examination of the uncertainty of experience curve formulations on the outcomes of energy and environmental policy analyses that extend over many decades.

description: My mother told me three stories about the Second World War which illustrate that during wartime those who died and those who lived was often determined by chance - by the roll of the dice - whether one was in the military or was a civilian.In December 1940 my mother Daphne Consterdine was working in Radcliffe, Lancashire, and at night doing fire watch and first aid duty. Twice she was almost killed.During the 1940 Christmas Blitz on Manchester Daphne and another young woman were at Radcliffe on fire duty on the roof of Woolworths store. They were supplied with water, a hose, a foot pump, and a bucket of sand. In the distance Manchester, under attack, was a red glow which if you didn't know that it was the whole city being bombed and burned would have looked beautiful. Suddenly a German bomber came overhead and an incendiary bomb fell onto the roof, causing a fire. Daphne pumped with her foot and her companion held the nozzle of the short hose to direct it onto the fire; they changed over, with Daphne holding the nozzle. Suddenly the water stopped coming out of the hose. Daphne looked behind her and right there was a quivering piece of shrapnel, like a great sword, stuck in the roof inches behind her, which had cut the hose, having fallen between the two fortunate young women. If the shrapnel had fallen a foot nearer to Daphne it would have killed her.On another occasion Daphne was due to go on night duty at a First Aid Post. A colleague at work had been scheduled for duty on the following night, but it was a night when the colleague wanted to go out on a date. The two women agreed to swap nights, and the colleague went on duty on Daphne's night. The girl didn't come in to work next day, and that evening Daphne went to the First Aid Post to begin her duty and found just a hole in the ground - the hut had received a direct hit by a German bomb, and it would have been Daphne killed in the hut if she hadn't swapped her duty night!After the war my mother's employer in the early 1950s, Mr Woodward Weaver, told her of his own chance escape from death. In a battle area he was driving an open-top vehicle with a man sitting beside him on his left when he stopped to talk to a soldier on foot, on his right. A German shell exploded among them. The men on each side of Mr Weaver were killed yet he was left untouched. The dice had landed his way.

description: It is commonly believed that the LHVTs can be tested through measuring the Bell's inequalities. This scheme, for the massive particle system, was originally set up for the entangled K^0\bar{K^0} pair system from the ϕfactory. In this Letter we show that the J/Ψ-> K^0\bar{K^0} process is even more realistic for this goal. We analyze the unique properties of J/Ψin the detection of basic quantum effects, and find that it is possible to use J/Ψdecay as a test of LHVTs in the future τ-Charm factory. Our analyses and conclusions are generally also true for other heavy Onium decays.
