Paying people for getting vaccinated? : a favorable solution for both vaccine-hesitant persons and the public

Subjects: subject: 179

description: Assume a pandemic in which, despite all efforts of vaccine persuasion, too many people are hesitant toward vaccination for a laissez-faire regime to reach herd immunity on a strictly voluntary basis. Then, basically four policy options are available—(a) moral appeals, (b) legal obligation, (c) monetary fines, and (d) monetary rewards. In this article, we demonstrate that the prevalent vaccination debate chooses the wrong starting point in discussing these options. Rather than asking how vaccine hesitancy can be overcome as a (bothersome) hindrance toward reaching herd immunity, we ask how one can reach herd immunity in due time while minimizing the (subjectively perceived) offense to the dignity of vaccine-hesitant citizens. This change in perspective favors paying people for getting vaccinated instead of sanctioning them for not doing so. With respect to the COVID-19 crisis, we show that a payment strategy is both feasible and advisable. This may be an important insight not only in the short term, but also with respect to future pandemics that are likely to come.

Fredkin and Toffoli gates implemented in Oregonator model of Belousov-Zhabotinsky medium
Creators: name: Adamatzky, Andrew

Year: 2016
Subjects: subject: Emerging Technologies (cs.ET)
subject: FOS: Computer and information sciences

description: A thin-layer Belousov-Zhabotinsky (BZ) medium is a powerful computing device capable for implementing logical circuits, memory, image processors, robot controllers, and neuromorphic architectures. We design the reversible logical gates --- Fredkin gate and Toffoli gate --- in a BZ medium network of excitable channels with sub-excitable junctions. Local control of the BZ medium excitability is an important feature of the gates' design. A excitable thin-layer BZ medium responds to a localised perturbation with omnidirectional target or spiral excitation waves. A sub-excitable BZ medium responds to an asymmetric perturbation by producing travelling localised excitation wave-fragments similar to dissipative solitons. We employ interactions between excitation wave-fragments to perform computation. We interpret the wave-fragments as values of Boolean variables. A presence of a wave-fragment at a given site of a circuit represents logical truth, absence of the wave-fragment --- logical false. Fredkin gate consists of ten excitable channels intersecting at eleven junctions eight of which are sub-excitable. Toffoli gate consists of six excitable channels intersecting at six junctions four of which are sub-excitable. The designs of the gates are verified using numerical integration of two-variable Oregonator equations.

description: The project reviewed the management of death in England in the period 1939-1979 using a number of methods, including interviews with retired cemetery managers. These interviews invited the respondents to detail their career in cemetery management and reflect on burial culture during that period. The interviews gave an insight into the way cemetery management was dealt with as a local authority service; the work of cemetery management, which included both technical aspects of the job and its ‘vocational’ quality with regard to contact with bereaved people; and changes in landscape style.

description: Tremendous growing demand for high data rate services such as video, gaming and social networking in wireless cellular systems, attracted researchers' attention to focus on developing proximity services. In this regard, device-to-device (D2D) communications as a promising technology for future cellular systems, plays crucial rule. The key factor in D2D communication is providing efficient peer discovery mechanisms in ultra dense networks. In this paper, we propose a centralized D2D discovery scheme by employing a signaling algorithm to exchange D2D discovery messages between network entities. In this system, potential D2D pairs share uplink cellular users' resources with collision detection, to initiate a D2D links. Stochastic geometry is used to analyze system performance in terms of success probability of the transmitted signal and minimum required time slots for the proposed discovery scheme. Extensive simulations are used to evaluate the proposed system performance.

description: This project explores what makes numeracy further education in different geographical areas in England.

 Its specific aims are:

to investigate ways in which teachers' knowledge of learners' numerate practices outside the classroom inform numeracy teaching inside the classroom

to investigate learners' reasons and motivations for attending adult numeracy classes

to explore and describe some of the ways in which learning numeracy transforms learners' identities within and outside the classroom

to investigate what learners consider being a numerate adult means in today's society

to find out from learners how they use numeracy outside the classroom

to describe and analyse how learners approach particular mathematical tasks/problems based in contexts outside the classroom.

 The project investigated four adult numeracy classes which were working between Entry Level 1 and Level 2. The dataset comprises the interviews carried out with students, with the addition of some notes from teacher-researchers and some extracts from student diaries. The two principal methods of data collection were semi-participant observation within the classroom and loosely structured interviews. The study explored a particular and limited cohort of adult learners: these were students who attended discrete numeracy classes on a voluntary basis, who worked with very good teachers and were generally very well motivated. As this is a relatively small scale, interpretative project the researchers are unable to claim that their findings are representative of a larger population. Nevertheless, they consider their findings have wider implications for the teaching and learning of adult numeracy.

description: Ultracold atoms placed in a tight cigar-shaped trap are usually described in terms of the Lieb-Liniger model. We study the extensions of this model which arise when van der Waals interaction between atoms is taken into account. We find that the corrections induced by the finite range of interactions can become especially important in the vicinity of narrow Feshbach resonances and suggest realistic schemes of their experimental detection. The interplay of confinement and interactions can lead to effective transparency where the one-dimensional interactions are weak in a wide range of parameters.

description: The capillary flow of a ferrofluid in a single cylindrical capillary tube and through a sandy porous medium under the action of a non-uniform magnetic field is studied experimentally. The dynamics of the capillary rise and the static case have been considered. It has been shown that the non-uniform magnetic field with upward directed gradient accelerates the capillary rise; contrary, the non-uniform magnetic field with downward directed gradient decelerates the capillary rise. Time dependences of the ferrofluid height and maximum reachable height of ferrofluid have been analyzed. The method of the study of ferrofluid capillary rise based on the use of magnetic measurements has been proposed. It has been demonstrated that porous material parameters can be extracted from the results of measurements of the inductances of the solenoid with porous medium inside and the small sensing coil within a single experiment.

description: Outflows in active galaxies (AGNs) are common, although their launching mechanism, location, and physical impact on the host galaxy remain controversial. We conducted a multiwavelength six-month campaign to observe the nearby Seyfert galaxy NGC 7469 with several observatories in order to better understand and quantify the outflow in this AGN. We report on the time-integrated line-resolved X-ray spectrum of NGC 7469 obtained with the Reflection Grating Spectrometer (RGS) on board XMM-Newton. We use the RGS spectrum to discern the many AGN outflow components. A global fit is applied to obtain their physical parameters. We find that the AGN wind can be well described by three narrow velocity components at -650, -950, and -2050 km/s. The RGS clearly resolves the -20 50 km/s component in C5+ Ly$α$, while the -650 km/s and -950 km/s velocities are blended. Similar velocities are resolved in the UV. The H-equivalent column densities of these components are, respectively, NH = 7x10^20, 2.2x10^21, and 10^20 cm^-2, for a total of 3x10^21 cm^-2. The -650 km/s component shows a broad ionisation distribution. We identify a photo-ionised emission component blue-shifted by -450 km/s which we ascribe to the same outflow that produces the absorption lines. The elemental abundance ratios of C, N, Ne, S, and Fe to O in the outflow tend to be between 1 - 2 times solar. Preliminary estimates of the absorber distance from the AGN center suggest it is at least a few pc away from the center, but more advanced methods need to be applied in order to obtain better constraints. The complex X-ray spectrum of NGC 7469 demonstrates the richness of high energy phenomena taking place in AGN cores. The subtle spectroscopic differences between the various components require deep, high-resolution observations, such as the present RGS spectrum, if one is to resolve them and perform quantitative plasma diagnostics.

description: Possible formation mechanisms of massive close binary black holes that can merge in the Hubble time to produce powerful gravitational wave bursts detected during advanced LIGO O1 science run are briefly discussed. The pathways include the evolution from field low-metallicity massive binaries, the dynamical formation in globular clusters and primordial black holes. Low effective black hole spins inferred for LIGO GW150914 and LTV151012 events are discussed. Population synthesis calculations of the expected spin and chirp mass distributions from the standard field massive binary formation channel are presented for different metallicities (from zero-metal Population III stars up to solar metal abundance). We conclude that that merging binary black holes can contain systems from different formation channels, discrimination between which can be made with increasing statistics of mass and spin measurements from ongoing and future gravitational wave observations.

description: Quasi--local scalar variables approach is applied to a spherically symmetric inhomogeneous Lema\^ıtre--Tolman--Bondi metric containing a mixture of non-relativistic cold dark matter and coupled dark energy with constant equation of state. The quasi--local coupling term considered is proportional to the quasi--local cold dark matter energy density and a quasi--local Hubble factor-like scalar via a coupling constant $α$. The autonomous numerical system obtained from the evolution equations is classified for different choices of the free parameters: the adiabatic constant of the dark energy $w$ and $α$. The presence of a past attractor in a non-physical region of the energy densities phase-space of the system makes the coupling term non physical when the energy flows from the matter to the dark energy in order to avoid negative values of the dark energy density in the past. On the other hand, if the energy flux goes from dark energy to dark matter, the past attractor lays in a physical region. The system is also numerically solved for some interesting initial profiles leading to different configurations: an ever expanding mixture, a scenario where the dark energy is completely consumed by the non-relativistic matter by means of the coupling term, a scenario where the dark energy disappears in the inner layers while the outer layers expand as a mixture of both sources, and, finally, a structure formation toy model scenario, where the inner shells containing the mixture collapse while the outer shells expand.

description: We describe the hardware, gateware, and software developed at Raytheon BBN Technologies for dynamic quantum information processing experiments on superconducting qubits. In dynamic experiments, real-time qubit state information is fedback or fedforward within a fraction of the qubits' coherence time to dynamically change the implemented sequence. The hardware presented here covers both control and readout of superconducting qubits. For readout we created a custom signal processing gateware and software stack on commercial hardware to convert pulses in a heterodyne receiver into qubit state assignments with minimal latency, alongside data taking capability. For control, we developed custom hardware with gateware and software for pulse sequencing and steering information distribution that is capable of arbitrary control flow on a fraction superconducting qubit coherence times. Both readout and control platforms make extensive use of FPGAs to enable tailored qubit control systems in a reconfigurable fabric suitable for iterative development.

description: There is a long-standing experimental observation that the melting of topologically constrained DNA, such as circular-closed plasmids, is less abrupt than that of linear molecules. This finding points to an intriguing role of topology in the physics of DNA denaturation, which is however poorly understood. Here, we shed light on this issue by combining large-scale Brownian Dynamics simulations with an analytically solvable phenomenological Landau mean field theory. We find that the competition between melting and supercoiling leads to phase coexistence of denatured and intact phases at the single molecule level. This coexistence occurs in a wide temperature range, thereby accounting for the broadening of the transition. Finally, our simulations show an intriguing topology-dependent scaling law governing the growth of denaturation bubbles in supercoiled plasmids, which can be understood within the proposed mean field theory.

description: Silicon ring resonators are used as photon pair sources by taking advantage of silicon's large third order nonlinearity with a process known as spontaneous four wave mixing. These sources are capable of producing pairs of indistinguishable photons but typically suffer from an effective $50\%$ loss. By slightly decoupling the input waveguide from the ring, the drop port coincidence ratio can be significantly increased with the trade-off being that the pump is less efficiently coupled into the ring. Ring resonators with this design have been demonstrated having coincidence ratios of $\sim 96\%$ but requiring a factor of $\sim 10$ increase in the pump power. Through the modification of the coupling design that relies on additional spectral dependence, it is possible to achieve similar coincidence ratios without the increased pumping requirement. This can be achieved by coupling the input waveguide to the ring multiple times, thus creating a Mach-Zehnder interferometer. This coupler design can be used on both sides of the ring resonator so that resonances supported by one of the couplers are suppressed by the other. This is the ideal configuration for a photon-pair source as it can only support the pump photons at the input side while only allowing the generated photons to leave through the output side. Recently, this device has been realized with preliminary results exhibiting the desired spectral dependence and with a coincidence ratio as high as $\sim 97\%$ while allowing the pump to be nearly critically coupled to the ring. The demonstrated near unity coincidence ratio infers a near maximal heralding efficiency from the fabricated device. This device has the potential to greatly improve the scalability and performance of quantum computing and communication systems.

description: The dressed states arising from the interaction between electrons and holes, and off-resonant electromagnetic radiation have been investigated for recently fabricated gapped and anisotropic black phosphorus. Our calculations were carried out for the low-energy electronic subbands near the $Γ$ point. States for both linear and circular polarizations of the incoming radiation have been computed. However, our principal emphasis is on linearly polarized light with arbitrary polarization since this case has not been given much attention for dressing fields imposed on anisotropic structures. We have considered various cases for one- and few-layer phosphorus, including massless Dirac fermions with tunable in-plane anisotropy. Initial Hamiltonian parameters are renormalized in a largely different way compared to those for previously reported for gapped Dirac structures and, most importantly, existing anisotropy which could be modified in every direction.

description: The Rafita asteroid family is an S-type group located in the middle main belt, on the right side of the 3J:-1A mean-motion resonance. The proximity of this resonance to the family left side in semi-major axis caused many former family members to be lost. As a consequence, the family shape in the $(a,1/D)$ domain is quite asymmetrical, with a preponderance of objects on the right side of the distribution. The Rafita family is also characterized by a leptokurtic distribution in inclination, which allows the use of methods of family age estimation recently introduced for other leptokurtic families such as Astrid, Hansa, Gallia, and Barcelona. In this work we propose a new method based on the behavior of an asymmetry coefficient function of the distribution in the $(a,1/D)$ plane to date incomplete asteroid families such as Rafita. By monitoring the time behavior of this coefficient for asteroids simulating the initial conditions at the time of the family formation, we were able to estimate that the Rafita family should have an age of $490\pm200$ Myr, in good agreement with results from independent methods such as Monte Carlo simulations of Yarkovsky and Yorp dynamical induced evolution and the time behaviour of the kurtosis of the $\sin{(i)}$ distribution. Asteroids from the Rafita family can reach orbits similar to 8\% of the currently known near Earth objects. $\simeq$1\% of the simulated objects are present in NEO-space during the final 10 Myr of the simulation, and thus would be comparable to objects in the present-day NEO population.

description: Star forming galaxies are believed to be a major source of Lyman Continuum (LyC) radiation responsible for reionizing the early Universe. Direct observations of escaping ionizing radiation have however been few and with low escape fractions. In the local Universe, only ~10 emitters have been observed, with typical escape fractions of a few percent. The mechanisms regulating this escape need to be strongly evolving with redshift in order to account for the Epoch of Reionization. Gas content and star formation feedback are among the main suspects, known to both regulate neutral gas coverage and evolve with cosmic time. In this paper, we reanalyze HST-COS spectrocopy of the first detected local LyC leaker, Haro 11. We examine the connection between LyC leakage and Lyman-$α$ line shape, and feedback-influenced neutral ISM properties like kinematics and gas distribution. We discuss the two extremes of an optically thin, density bounded ISM and a riddled, optically thick, ionization bounded ISM, and how Haro 11 fits into their theoretical predictions. We find that the most likely ISM model is a clumpy neutral medium embedded in a highly ionized medium with a combined covering fraction of unity and a residual neutral gas column density in the ionized medium high enough to be optically thick to Lyman-$α$, but low enough to be at least partly transparent to Lyman continuum and undetected in Si II. This suggests that SF feedback and galaxy-scale interaction events play a major role in opening passageways for ionizing radiation through the neutral medium.

Developing Sustainable Technologies for Waste: Improving Uptake through Partnership, 2004-2006
Creators: name: Slater, R.

Publisher: name: UK Data Service

description: Sustainable waste management is one of the biggest environmental challenges facing the United Kingdom (UK). European and national legislation is beginning to require a fundamental shift from waste disposal - predominantly landfill in the UK - to a more integrated style of resource management involving sustainable technologies that deliver waste minimisation, re-use, recycling and composting. Although these principles have underpinned the development of national waste strategies for a number of years, successive regulatory and economic measures have so far failed to deliver. Many recycling and composting technologies are well established overseas, but with a recycling rate around 12 per cent, their uptake in the UK remains marginal. The main problem is not the development of appropriate systems and technologies, but the factors affecting their uptake.

 Developing Sustainable Technologies for Waste: Improving Uptake through Partnership, 2004-2006 aims to investigate the potential for multi-agent partnerships between local authorities, local/small businesses, and the community sector for developing and delivering public policy and sustainable technologies. The study identifies local authorities as key players in waste management. The case studies used are based in different Local Authority boundaries.

 The study is part of the Sustainable Technologies Programme (STP) which is a major research initiative by the ESRC. It funds innovative and policy-relevant research on the social and economic processes that shape, foster or inhibit more sustainable technologies. More information can be found at the Sustainable Technologies Programme web page. The study is project 8.

Doing Youth Justice: Analysing Risk and Need Assessments in Youth Justice Practice, 2004-2005
Creators: name: Phoenix, J.
Publisher: name: UK Data Service
Year: 2009

description: The past decade has seen a rapid expansion of the numbers of young people drawn into the criminal justice system and custody. This study investigates how youth justice practitioners (including Youth Offending Team (YOT) workers, solicitors, police and lay magistrates) assess the risks and needs of young law-breakers, and make decisions and recommendations. The study also explores how the young offenders themselves engage in these processes.

 A case study approach has been adopted where all individuals routinely involved in processing young law-breakers from a single small Local Authority have been interviewed. A sample of young offenders have also been interviewed. Six months of ethnographic observations of the youth court and YOT meetings and key policy meetings within the Magistrates’ Court, Local Authority and police authority were used to supplement interview materials. Currently, only the interview transcripts are available from the UKDA.

 Further information can be found about the project on the ESRC web page.

description: In vitro study suggested that A2BR agonists can induce PD-L1 expression through induction of NF-kB pathway, while the inhibitors of NF-kB pathway can partially reverse the promoting effect of A2BR on PD-L1 expression. High A2BR expression in OSCC was associated with lower infiltration of NK cells. Importantly, A2BR inverse agonists and/or PD-L1 antibody treatment promoted the recruitment of NK cells toward OSCC supernatant and increase the cytotoxicity of NK cells against OSCC cells.
Radio-frequency microstructure and polarization in ion-proton pulsars

description: It is shown that the time-variability inherent in the ion-proton polar cap leads naturally to growth of Langmuir modes on narrow bundles of magnetic flux lines and that the observed size of micropulses is consistent with the smallest such bundle that can plausibly support the growth of the modes. The polarization of integrated profiles is revisited, specifically, the pi/2 position-angle jumps that are frequently observed accompanied by a zero in polarization. The fact that radiation emitted above ion-proton polar caps is not tangential to the local flux lines but has a finite angular distribution proves to be the essence of understanding this phenomenon as is a constraint on the shape of the polar cap. In principle, the behaviour should also be seen if the form of the polar-cap ion-proton area in a single pulse satisfies certain conditions which are explained here.

description: Il volume illustra gli esiti di una ricerca, ancora in corso, sull’apporto di Egle Renata Trincanato (1910-1998) alla disciplina del Restauro. Lo studio fa parte di una ricerca più ampia svolta in seno alla cattedra di Restauro dell’Università degli Studi di Cagliari, coordinata da Caterina Giannattasio, tesa a integrare lo stato dell’arte con il contributo delle figure femminili che hanno operato nell’ambito dell’intervento sul patrimonio culturale. L’indagine qui presentata è stata condotta a partire dall’esplorazione del fondo d’archivio conservato presso l’Archivio Progetti dello IUAV di Venezia. L’intento è quello di inquadrare il pensiero della studiosa nel contesto del Secondo Dopoguerra, in un momento in cui il tema della salvaguardia della città storica è al centro del dibattitto nazionale e internazionale. Trincanato, intrecciando le competenze nella lettura del tessuto urbano, l’impegno nella tutela della città e la spiccata sensibilità per i temi sociali, svolge un ruolo cruciale nella declinazione alla scala urbana della disciplina del Restauro.

Post-injection normal closure of fractures as a mechanism for induced seismicity

description: Understanding the controlling mechanisms underlying injection-induced seismicity is important for optimizing reservoir productivity and addressing seismicity-related concerns related to hydraulic stimulation in Enhanced Geothermal Systems. Hydraulic stimulation enhances permeability through elevated pressures, which cause normal deformations, and the shear slip of pre-existing fractures. Previous experiments indicate that fracture deformation in the normal direction reverses as the pressure decreases, e.g., at the end of stimulation. We hypothesize that this normal closure of fractures enhances pressure propagation away from the injection region and significantly increases the potential for post-injection seismicity. To test this hypothesis, hydraulic stimulation is modeled by numerically coupling fracture deformation, pressure diffusion and stress alterations for a synthetic geothermal reservoir in which the flow and mechanics are strongly affected by a complex three-dimensional fracture network. The role of the normal closure of fractures is verified by comparing simulations conducted with and without the normal closure effect.

description: Riemannian geometry is a particular case of Hamiltonian mechanics: the orbits of the hamiltonian $H=\frac{1}{2}g^{ij}p_{i}p_{j}$ are the geodesics. Given a symplectic manifold (Γ,ω), a hamiltonian $H:Γ\to\mathbb{R}$ and a Lagrangian sub-manifold $M\subsetΓ$ we find a generalization of the notion of curvature. The particular case $H=\frac{1}{2}g^{ij}\left[p_{i}-A_{i}\right]\left[p_{j}-A_{j}\right]+ϕ$ of a particle moving in a gravitational, electromagnetic and scalar fields is studied in more detail. The integral of the generalized Ricci tensor w.r.t. the Boltzmann weight reduces to the action principle $\int\left[R+\frac{1}{4}F_{ik}F_{jl}g^{kl}g^{ij}-g^{ij}\partial_{i}ϕ\partial_{j}ϕ\right]e^{-ϕ}\sqrt{g}d^{n}q$ for the scalar, vector and tensor fields.

description: We have observed the Vela pulsar for one year using a Phased Array Feed (PAF) receiver on the 12-metre antenna of the Parkes Test-Bed Facility. These observations have allowed us to investigate the stability of the PAF beam-weights over time, to demonstrate that pulsars can be timed over long periods using PAF technology and to detect and study the most recent glitch event that occurred on 12 December 2016. The beam-weights are shown to be stable to 1% on time scales on the order of three weeks. We discuss the implications of this for monitoring pulsars using PAFs on single dish telescopes.

description: A fundamental challenge in large-scale cloud networks and data centers is to achieve highly efficient server utilization and limit energy consumption, while providing excellent user-perceived performance in the presence of uncertain and time-varying demand patterns. Auto-scaling provides a popular paradigm for automatically adjusting service capacity in response to demand while meeting performance targets, and queue-driven auto-scaling techniques have been widely investigated in the literature. In typical data center architectures and cloud environments however, no centralized queue is maintained, and load balancing algorithms immediately distribute incoming tasks among parallel queues. In these distributed settings with vast numbers of servers, centralized queue-driven auto-scaling techniques involve a substantial communication overhead and major implementation burden, or may not even be viable at all. Motivated by the above issues, we propose a joint auto-scaling and load balancing scheme which does not require any global queue length information or explicit knowledge of system parameters, and yet provides provably near-optimal service elasticity. We establish the fluid-level dynamics for the proposed scheme in a regime where the total traffic volume and nominal service capacity grow large in proportion. The fluid-limit results show that the proposed scheme achieves asymptotic optimality in terms of user-perceived delay performance as well as energy consumption. Specifically, we prove that both the waiting time of tasks and the relative energy portion consumed by idle servers vanish in the limit. At the same time, the proposed scheme operates in a distributed fashion and involves only constant communication overhead per task, thus ensuring scalability in massive data center operations.

Are gravitational waves spinning down PSR J1023+0038?

description: The pulsar J1203+0038 rotates with a frequency $ν\approx 592$ Hz and has been observed to transition between a radio state, during which it is visible as a millisecond radio pulsar, and and a Low Mass X-ray Binary state, during which accretion powered X-ray pulsations are visible. Timing during the two phases reveals that during the LMXB phase the neutron star is spinning down at a rate of $\dotν\approx -3 \times 10^{-15}$ Hz/s, which is approximately 27\% faster than the rate measured during the radio phase, $\dotν\approx -2.4 \times 10^{-15}$ Hz/s, and at odds with the predictions of accretion models. In this letter we suggest that the increase in spin-down rate is compatible with gravitational wave emission, and in particular to the creation of a `mountain' during the accretion phase. We show that asymmetries in pycno-nuclear reaction rates in the crust can lead to a large enough mass quadrupole to explain the observed spin-down rate, which so far has no other self-consistent explanation, and that radio timing at the onset of the next millisecond radio pulsar phase can test this scenario. Another possibility is that an unstable $r$-mode with amplitude $α\approx 5\times10^{-8}$ may be present in the system.
