description: The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the universe using the baryon acoustic oscillations technique. The spectra of 35 million galaxies and quasars over 14,000 square degrees will be measured during a 5-year survey. A new prime focus corrector for the Mayall telescope at Kitt Peak National Observatory will deliver light to 5,000 individually targeted fiber-fed robotic positioners. The fibers in turn feed ten broadband multi-object spectrographs. We describe the ProtoDESI experiment, that was installed and commissioned on the 4-m Mayall telescope from August 14 to September 30, 2016. ProtoDESI was an on-sky technology demonstration with the goal to reduce technical risks associated with aligning optical fibers with targets using robotic fiber positioners and maintaining the stability required to operate DESI. The ProtoDESI prime focus instrument, consisting of three fiber positioners, illuminated fiducials, and a guide camera, was installed behind the existing Mosaic corrector on the Mayall telescope. A Fiber View Camera was mounted in the Cassegrain cage of the telescope and provided feedback metrology for positioning the fibers. ProtoDESI also provided a platform for early integration of hardware with the DESI Instrument Control System that controls the subsystems, provides communication with the Telescope Control System, and collects instrument telemetry data. Lacking a spectrograph, ProtoDESI monitored the output of the fibers using a Fiber Photometry Camera mounted on the prime focus instrument. ProtoDESI was successful in acquiring targets with the robotically positioned fibers and demonstrated that the DESI guiding requirements can be met.

description: Background: In the past decade, several smoking cessation interventions have been developed and implemented through information and communication technology (ICT). Evidence suggests that they might be suitable for large-scale public health interventions, based on updated communication media characteristics in terms of interplay between technology and graphical user interface, reaching high numbers of individuals. Objectives: We aimed at estimating web/text-based interventions effectiveness as compared with approaches routinely used for general population, that is smoking assessment or non-electronic self-help materials. Methods: A systematic review and meta-analysis was performed searching through PubMed, Embase and PsycInfo databases, as well as references of relevant papers. Heterogeneity and risk of bias were evaluated following standard methods. In addition, we performed meta-regression analyses testing if candidate covariates moderate the overall effect. Results: Slight but significant effectiveness was found for eHealth interventions over control conditions (RR = 1.28, 95% CI: 1.14–1.45). Meta-regressions showed similar findings for web- and text-based interventions. The effect seemed moderated by the follow-up period, being higher at 3 months and lower at 6/7 months follow-up. Conclusions: Our results outline moderate effectiveness of web/text-based interventions. However, a paucity of properly controlled studies and lack of information on several effect modifiers still hamper the development and implementation of smoking cessation interventions through ICT.

description: We propose a solution for Active Visual Search of objects in an environment, whose 2D floor map is the only known information. Our solution has three key features that make it more plausible and robust to detector failures compared to state-of-the-art methods: (i) it is unsupervised as it does not need any training sessions. (ii) During the exploration, a probability distribution on the 2D floor map is updated according to an intuitive mechanism, while an improved belief update increases the effectiveness of the agent's exploration. (iii) We incorporate the awareness that an object detector may fail into the aforementioned probability modelling by exploiting the success statistics of a specific detector. Our solution is dubbed POMP-BE-PD (Pomcp-based Online Motion Planning with Belief by Exploration and Probabilistic Detection). It uses the current pose of an agent and an RGB-D observation to learn an optimal search policy, exploiting a POMDP solved by a Monte-Carlo planning approach. On the Active Vision Database benchmark, we increase the average success rate over all the environments by a significant 35% while decreasing the average path length by 4% with respect to competing methods. Thus, our results are state-of-the-art, even without using any training procedure.

description: My grandfather built the air raid shelter, which is why I am here to tell the tale. Over a certain income, householders had to provide their own shelter—otherwise, they got an Anderson or a Morrison shelter. My father joined the Royal Signals when the pits in the Rhondda Valley started to close down in the '30s. When WWII broke out, he was sent to Prestatyn Holiday Camp, which had been requisitioned by the Army as a training base after it had only been open for a week.My mother, seven months pregnant with me, went to stay with my grandparents in Ladywell, Lewisham. One night, the air raid siren sounded, and my mother and grandmother went into the shelter. Grandad was out on duty, mending gas mains when the bombs dropped. The next morning, Grandad came home to find that a bomb had dropped (aiming for the railway lines that ran along the end of the garden), and there was a pile of earth where the shelter used to be. He and the neighbours started digging for the door, but it wasn't there. They kept on digging around the side to find that the shelter had turned 180 degrees in the ground, and my mother and grandmother were shaken but unharmed.The next day, we got on the train and spent the rest of the war in Prestatyn, which is where I was born two months later. I was the second baby to be christened in the camp church. We went back there for a holiday in the '50s.One of the memories I have is of standing on Prestatyn's sandy beach, watching what I thought was a firework display but was, in reality, the bombing of Liverpool Docks.

description: Extremely high velocity (EHV) wings, with full widths of 72 to 140 km/s, are seen on the CO J=3-2 lines toward W3 IRS 5, GL 490, NGC 2071, W28 A2, GL 2591, S140, and Cepheus A. The results of our survey suggest that EHV wings are common around infrared sources of moderate to high luminosity (500 to 4x10^5 Lsun) in dense regions. Line ratios imply that the EHV gas is usually optically thin and warm. Characteristic velocities range from 20 to 40 km/s, yielding timescales of 1600-4200 yr. Since most sources in this study are producing some ionizing photons, these short timescales suggest that neutral winds coexist with ionizing photons. We examined two possible sources for the EHV CO emission: a neutral stellar wind; and swept-up or entrained molecular gas. Neither can be ruled out. If the high-velocity (HV) gas is swept up by a momentum-conserving stellar wind traced by the extremely high velocity CO emission, most of the C in the winds from luminous objects cannot be in CO. If the EHV and HV forces are equal, the fraction of C in a form other than CO increases with source luminosity and with the production rate of ionizing photons.

description: This paper presents a novel approach to vehicle positioning that operates without reliance on the global navigation satellite system (GNSS). Traditional GNSS approaches are vulnerable to interference in certain environments, rendering them unreliable in situations such as urban canyons, under flyovers, or in low reception areas. This study proposes a vehicle positioning method based on learning the road signature from accelerometer and gyroscope measurements obtained by an inertial measurement unit (IMU) sensor. In our approach, the route is divided into segments, each with a distinct signature that the IMU can detect through the vibrations of a vehicle in response to subtle changes in the road surface. The study presents two different data-driven methods for learning the road segment from IMU measurements. One method is based on convolutional neural networks and the other on ensemble random forest applied to handcrafted features. Additionally, the authors present an algorithm to deduce the position of a vehicle in real-time using the learned road segment. The approach was applied in two positioning tasks: (i) a car along a 6[km] route in a dense urban area; (ii) an e-scooter on a 1[km] route that combined road and pavement surfaces. The mean error between the proposed method's position and the ground truth was approximately 50[m] for the car and 30[m] for the e-scooter. Compared to a solution based on time integration of the IMU measurements, the proposed approach has a mean error of more than 5 times better for e-scooters and 20 times better for cars.

description: We present a solution for the relative positions and orientations of the four CCD chips on the Hubble Space Telescope (HST) Planetary Camera (PC). An accurate solution is required when matching HST images with ground-based images or with one another. The solution is accurate to about 1/4 PC pixel or about $0{.\hskip-2pt ''} 01$, a 30-fold improvement over the best previous solution. The CCDs are rotated relative to one another by up to $1^\circ$. The solution is based on images taken between December 1990 and June 1992 and is stable over that entire period. We find that the pixel size is $0{.\hskip-2pt ''}04373\pm 0{.\hskip-2pt ''}00004$ based on comparison with HST Guide Stars, in good agreement with previous Guide-Star based calibrations but $\sim 1\%$ smaller than a globular-cluster based calibration.

The electric field of a point charge in a spherical inclusion structure

description: A point charge in the presence of a metallic nanoshpere is a fundamental setup, which has implications for Raman scattering, enhancement of spontaneous emission of a molecule by an antenna, sensing, and modeling a metallic tip in proximity to a nanoparticle. Here, we analytically expand the electric field of a point charge in an $ε_{2}$ host medium in the presence of an $ε_{1}$ sphere using the sphere eigenstates, where $ε_1$ and $ε_2$ can take any values. Only the $m=0$ spherical harmonics are employed in the expansion and the calculation of the potential and the electric field is very simple. The electric field is strongly enhanced when $ε_{1}/ε_2$ is close to an $(ε_{1}/ε_2)_l$ eigenvalue of a dominant mode, which is determined by the point charge location and the measurement point. An electric field exists inside the sphere when $ε_{1}/ε_2$ is close to a $(ε_{1}/ε_2)_l$ resonance even when $ε_1$ is a conductor. Low order modes generate an electric field far away from the interface, where the $l=1$ mode with a resonance at $ε_1=-2ε_2$ generates a field at the sphere center. The high order modes which are associated with high spatial frequencies become more dominant when the point charge approaches the sphere surface or when the physical parameters are close the high order modes resonances. When $ε_{1}/ε_2$ is smaller or larger than the eigenvalues of the dominant modes, the modes interfere constructively and generate a strong signal at an angular direction equal to that of the source. The spectral information at the sphere surface may be utilized to calculate the point charge location without knowing its magnitude.

description: Digital and interactive technologies are becoming increasingly embedded in everyday lives of people around the world. Application of technologies such as real-time, context-aware, and interactive technologies; augmented and immersive realities; social media; and location-based services has been particularly evident in urban environments where technological and sociocultural infrastructures enable easier deployment and adoption as compared to non-urban areas. There has been growing consumer demand for new forms of experiences and services enabled through these emerging technologies. We call this ambient media, as the media is embedded in the natural human living environment. The 8th Semantic Ambient Media Workshop Experience (SAME) Proceedings where based on a collaboration between the SEACHI Workshop Smart Cities for Better Living with HCI and UX, which has been organized by UX Indonesia and was held in conjunction with Computers and Human-Computer Interaction (CHI) 2016 in San Jose, CA USA.

description: Elongated anisotropic Gaussian filters are used for the orientation estimation of fibers. In cases where computed tomography images are noisy, roughly resolved, and of low contrast, they are the method of choice even if being efficient only in virtual 2D slices. However, minor inaccuracies in the anisotropic Gaussian filters can carry over to the orientation estimation. Therefore, this paper proposes a modified algorithm for 2D anisotropic Gaussian filters and shows that this improves their precision. Applied to synthetic images of fiber bundles, it is more accurate and robust to noise. Finally, the effectiveness of the approach is shown by applying it to real-world images of sheet molding compounds.

description: Physics beyond the simplest version of the standard electroweak model is required to reconcile the results of the chlorine and the Kamiokande solar neutrino experiments. None of the 1000 solar models in a full Monte Carlo simulation is consistent with the results of the chlorine or the Kamiokande experiments. Even if the solar models are forced articficially to have a ${}^8 B$ neutrino flux in agreement with the Kamiokande experiment, none of the fudged models agrees with the chlorine observations. This comparison shows that consistency of the chlorine and Kamiokande experiments requires some physical process that changes the shape of the ${}^8 B$ neutrino energy spectrum. The GALLEX and SAGE experiments, which currently have large statistical uncertainties, differ from the predictions of the standard solar model by $2 σ$ and $3 σ$, respectively. The possibility that the neutrino experiments are incorrect is briefly discussed.

description: We argue that fast interactions of the lightest singlet neutrino $N_1$ would project part of a preexisting lepton asymmetry $L_p$ onto a direction that is protected from $N_1$ washout effects, thus preventing it from being erased. In particular, we consider an asymmetry generated in $N_2$ decays, assuming that $N_1$ interactions are fast enough to bring $N_1$ into full thermal equilibrium. If $N_1$ decays occur at $T\gsim 10^9$ GeV, that is, before the muon Yukawa interactions enter into thermal equilibrium, then generically part of $L_p$ survives. In this case some of the constraints implied by the standard $N_1$ leptogenesis scenario hold only if $L_p \approx 0$. For $T\lsim 10^9$ GeV, $L_p$ is generally erased, unless special alignment/orthogonality conditions in flavor space are realized.

description: We investigate the angular distribution of the $γ$-ray bursts in the publicly available BATSE catalogue, using the measures of burst brightness $B$ and short time scale ($\simless$ 0.3 s) variability $V$ which we introduced earlier. We show that the 54 type I ($\log V \le -0.8$) bursts lying in the middle brightness range 490 counts $\le B \le$ 1250 counts (corresponding to 1/3 of all type I bursts) exhibit a Galactic dipole moment of $\langle \cos θ\rangle = 0.204 \pm 0.079$ {\it and} a deviation of the Galactic quadrupole moment from 1/3 of $\langle \sin^2 b \rangle - 1/3 = -0.104 \pm 0.041$. Using Monte Carlo simulations which include the BATSE sky exposure map and taking into account division of the type I bursts into three equal samples, we find that the probability by chance of an isotropic distribution of 54 bursts exhibiting values of $\langle \cos θ\rangle$ {\it and} the negative of $\langle \sin^2 b \rangle - 1/3$ which equal or exceed the observed values is $6.6 \times 10^{-5}$. We conclude that $γ$-ray bursts are Galactic in origin.

description: Dad always used to tell us a story about dancing with Lady Astor on Plymouth Hoe at the end of WWII. We assumed it was another of his "tall stories" until, decades later and a few years after his death in 1991, my sister spotted his picture in the Plymouth Evening Herald and realised that he had in fact been telling the truth! She took the newspaper to his sister, who of course knew him at the time and verified that it was indeed him. The photograph has featured frequently in articles about Plymouth in WWII and was also used in the exhibition about Nancy Astor in 2019 in Plymouth Guildhall. The Astor centenary event was also marked by a special bus, which travelled around Plymouth for the next two years with the Dancing Sailor photo displayed on it.
Radiative Yukawa Couplings for Supersymmetric Higgs Singlets at Large tan(beta)

description: Singlet Higgs bosons present in extensions of the MSSM can have sizable Yukawa couplings to the b quark and the tau lepton for large values of tan(beta) at the 1-loop level. We present an effective Lagrangian which incorporates these tan(beta)-enhanced Yukawa couplings and which enables us to study their effect on singlet Higgs-boson phenomenology within the context of both the mnSSM and the NMSSM. In particular, we find that the loop-induced coupling can be a significant effect for the singlet pseudoscalar, and may dominate its decay modes. Further implications of the tan(beta)-enhanced Yukawa couplings for the phenomenology of the singlet Higgs bosons are briefly discussed.

description: We report on the superconducting properties of molybdenum nitride thin films grown by reactive DC sputtering at room temperature with a N2:Ar mixture. Thin films grown using 5 % N2 concentration display Tc = 8 K, which is gradually reduced and abruptly disappears for 40 % N2 concentration. This suppression can be associated with changes in the nitrogen stoichiometry from Mo2N to MoN. Our results provide an effective and simple path to prepare Mo2Nx thin films with tunable Tc, which is relevant for the investigation of the fundamental properties and for technological applications.

Evidence That Gamma-Ray Burst Sources Repeat

description: We investigate clustering in the angular distribution of the 260 $γ$-ray bursts in the publicly available BATSE catalogue, using a nearest neighbour analysis and the measures of burst brightness $B$ and short time scale variability $V$ which we introduced earlier. We find that while all 260 bursts are only modestly clustered (Q-value = $1.8 \times 10^{-2}$), the 202 bursts in this sample for which the statistical error in their locations is $<9^\circ$ are significantly clustered on an angular scale $\approx 5^\circ$ (Q-value = $2.5 \times 10^{-4}$, taking into acoount having chosen the cutoff in the statistical error). We also find a significant correlation between bright type I bursts and faint type I and type II bursts on an angular scale $\approx 5^\circ$ (Q-value = $4.0 \times 10^{-3}$). This angular scale is smaller than the typical (statistical plus systematic) error in burst locations of $6.8^\circ$, suggesting multiple recurrences from individual sources. We conclude that ``classical'' $γ$-ray burst sources repeat on a time scale of months, and that many faint type I and II bursts come from the sources of bright type I bursts.

description: The structure of a vortex in the inner crust of a pulsar is calculated microscopically in the Wigner-Seitz cell approximation, simulating the conditions of the inner crust of a cold, non-accreting neutron star, in which a lattice of nuclei coexists with a sea of superfluid neutrons. The calculation is based on the axially deformed Hartree-Fock-Bogolyubov framework, using effective interactions. The present work extends and improves previous studies in four ways: i) it allows for the axial deformation of protons induced by the large deformation of neutrons due to the appearance of vortices; ii) it includes the effect of Coulomb exchange; iii) considers the possible effects of the screening of the pairing interaction; and iv) it improves the numerical treatment. We also demonstrate that the binding energy of the nucleus-vortex system can be used as a proxy to the pinning energy of a vortex and discuss in which conditions this applies. From our results, we can estimate the mesoscopic pinning forces per unit length acting on vortices. We obtain values ranging between $10^{14}$ to $10^{16}$ dyn/cm, consistent with previous findings.

On the inevitability of reionization: implications for cosmic microwave background fluctuations

description: Early photoionization of the intergalactic medium is discussed in a nearly model-independent way, in order to investigate whether early structures corresponding to rare Gaussian peaks in a CDM model can photoionize the intergalactic medium sufficiently early to appreciably smooth out the microwave background fluctuations. We conclude that this is indeed possible for a broad range of CDM normalizations and is almost inevitable for unbiased CDM, provided that the bulk of these early structures are quite small, no more massive than about 10^8 solar masses. Typical parameter values predict that reionization occurs around z=50, thereby suppressing fluctuations on degree scales while leaving the larger angular scales probed by COBE reasonably unaffected. However, for non-standard CDM, incorporating mixed dark matter, vacuum density or a tilted primordial power spectrum, early reionization plays no significant role.

The exponential laws for emission and decaying of entangled atoms

Year: 2017

description: The first photon emission and the disentanglement of a pair of identical bosonic atoms in excited entangled states follow an exponential law. We extend the theory to distinguishable and identical fermionic two-atom systems. As a byproduct of the analysis we determine the symmetries of the fermionic wave function. We also derive the emission distributions of excited atoms in product states, which must take into account the presence of simultaneous detections. Comparing both distributions reveals a direct manifestation of the modifications induced by entanglement on the atomic emission properties.
Did the universe recombine? New spectral constraints on reheating

description: One still cannot conclusively assert that the universe underwent a neutral phase, despite the new COBE FIRAS limit y<0.000025 on Compton y-distortions of the cosmic microwave background. Although scenarios where the very early (z=1000) ionization is thermal, caused by IGM temperatures exceeding 10000K, are clearly ruled out, there is a significant loophole for cosmologies with typical CDM parameters if the dominant ionization mechanism is photoionization. If the ionizing radiation has a typical quasar spectrum, then the y-constraint implies roughly h^{3/2}Ω_b Omega_0^{-1/4}<0.1 for fully ionized models. This means that BDM models with Omega_0 around 0.15 and reionization at about z=1000 are strongly constrained even in this very conservative case, and can survive the y test only if most of the baryons form BDM around the reionization epoch.

Contrastive-Signal-Dependent Plasticity: Self-Supervised Learning in Spiking Neural Circuits

description: Brain-inspired machine intelligence research seeks to develop computational models that emulate the information processing and adaptability that distinguishes biological systems of neurons. This has led to the development of spiking neural networks, a class of models that promisingly addresses the biological implausibility and {the lack of energy efficiency} inherent to modern-day deep neural networks. In this work, we address the challenge of designing neurobiologically-motivated schemes for adjusting the synapses of spiking networks and propose contrastive-signal-dependent plasticity, a process which generalizes ideas behind self-supervised learning to facilitate local adaptation in architectures of event-based neuronal layers that operate in parallel. Our experimental simulations demonstrate a consistent advantage over other biologically-plausible approaches when training recurrent spiking networks, crucially side-stepping the need for extra structure such as feedback synapses.

description: I start with an elementary observation about the pressure in the deconfined phase of a SU(3) gauge theory without quarks. This suggests a ``fuzzy'' bag model for the analogous pressure in QCD, with dynamical quarks. I then sketch how the deconfined phase might be described using an effective theory of Wilson lines. To leading order in weak coupling, the effective electric field appears in a form familiar from the lattice theory of Banks and Ukawa.
