description: Abstract: Silicon nanowires, due to their high surface-to-volume ratio, have demonstrated energy-efficient devices. In this work, we report on the fabrication and electrical characterization of the junctionless nanowire transistor, a transistor consisting of a highly doped nanowire channel without p-n junctions, where the flow of carriers is controlled by the gate potential. To fabricate these transistors, intrinsic silicon-on-insulator (SOI) wafers were n-doped by ion implantation. Flash lamp annealing was performed for dopant activation and mitigation of implantation defects. Nanowires were fabricated following a top-down approach using electron beam lithography and reactive ion etching. Electrical characterization of the fabricated devices is performed by back-gating. The devices show an on/off current ratio of approx. 106. This will be followed by the functionalization of the fabricated devices for the selective and highly sensitive electrical detection of ꞏOH and ꞏNO3 atmospheric radicals, which affect the air quality and climate and have a direct impact on our lives.

description: We have analyzed a broad-band optical and near-infrared spectrum of FU Tau A, a presumed young brown dwarf in the Taurus star forming region that has intrigued both theorists and observers by its over-luminosity in the HR diagram with respect to standard pre-main sequence evolutionary models. The new data, obtained with the X-Shooter spectrograph at the Very Large Telescope, include an unprecedented wealth of information on stellar parameters and simultaneously observed accretion and outflow indicators for FU Tau A. We present the first measurements of gravity (log g = 3.5 +- 0.5), radial velocity (RV = 22.5 +- 2.9 km/s), rotational velocity (v sin(i) = 20 +- 5 km/s) and lithium equivalent width (W_Li = 430 +- 20 mAA) for FUTau A. From the rotational velocity and the published period we infer a disk inclination of i ~ 50^deg. The lithium content is much lower than theoretically expected for such a young very low mass object, adding another puzzling feature to this object's properties. We determine the mass accretion rate of FU Tau A from comparison of the luminosities of 24 emission lines to empirical calibrations from the literature and find a mean of log (dM/dt)_acc [M_sun/yr] = -9.9 +- 0.2. The accretion rate determined independently from modeling of the excess emission in the Balmer and Paschen continua is consistent with this value. The corresponding accretion luminosity is too small to make a significant contribution to the bolometric luminosity. The existence of an outflow in FU Tau A is demonstrated through the first detection of forbidden emission lines from which we obtain an estimate for the mass loss rate, log (dM/dt)_out [M_sun/yr] < -10.4. The mass outflow and inflow rates can be combined to yield (dM/dt)_out / (dM/dt)_acc ~ 0.3, a value that is in agreement with jet launching models.

description: Very recent experiments have discovered that localized light in strongly absorbing media displays intriguing diffusive phenomena. Here we develop a first-principles theory of light propagation in open media with arbitrary absorption strength and sample length. We show analytically that photons in localized open absorbing media exhibit unusual Brownian motion. Specifically, wave transport follows the diffusion equation with the diffusion coefficient exhibiting spatial resolution. Most strikingly, despite that the system is controlled by two parameters -- the ratio of the localization (absorption) length to the sample length -- the spatially resolved diffusion coefficient displays novel single parameter scaling: it depends on the space via the returning probability. Our analytic predictions for this diffusion coefficient are confirmed by numerical simulations. In the strong absorption limit they agree well with the experimental results.

New Skyrme energy density functional for a better description of the Gamow-Teller Resonance

description: We present a new Skyrme energy density functional (EDF) named SAMi [Phys. Rev. C 86 031306(R)]. This interaction has been accurately calibrated to reproduce properties of doubly-magic nuclei and infinite nuclear matter. The novelties introduced in the model and fitting protocol of SAMi are crucial for a better description of the Gamow-Teller Resonance (GTR). Those are, on one side, the two-component spin-orbit potential needed for describing different proton high-angular momentum spin-orbit splitings and, on the other side, the careful description of the empirical hierarchy and positive values found in previous analysis of the spin (G_0) and spin-isospin (G_0^') Landau-Migdal parameters: 0 < G_0 < G_0^', a feature that many of available Skyrme forces fail to reproduce. When employed within the self-consistent Hartree-Fock plus Random Phase Approximation, SAMi produces results on ground and excited state nuclear properties that are in good agreement with experimental findings. This is true not only for the GTR, but also for the Spin Dipole Resonance (SDR) and the Isobaric Analog Resonance (IAR) as well as for the non charge-exchange Isoscalar Giant Monopole (ISGMR) and Isovector Giant Dipole (IVGDR) and Quadrupole Resonances (IVGQR).

description: We used radio observations of the neighbour galaxy M31 in order to put constraints on dark matter particle mass and annihilation cross section. Dark matter annihilation in M31 halo produces highly energetic leptons, which emit synchrotron radiation on radio frequencies in the galactic magnetic field. We predicted expected radio fluxes for the two annihilation channels: χχ-> bb* and χχ-> τ^+τ^-. We then compared them with available data on the central radio emission of M31 as observed by four radio surveys: VLSS (74 MHz), WENSS (325 MHz), NVSS (1400 MHz) and GB6 (4850 MHz). Assuming a standard NFW dark matter density profile and a conservative magnetic field distribution inside the Andromeda galaxy, we find that the thermal relic annihilation cross section = 3*10^{-26} cm^3/s or higher are only allowed for WIMP masses greater than 100 GeV and 55 GeV for annihilation into bb* and τ^+τ^- respectively. Taking into account potential uncertainties in the distributions of DM density and magnetic field, the mentioned WIMP limiting masses can be as low as 23 GeV for both channels, and as high as 280 and 130 GeV for annihilation into bb* and τ^+τ^- respectively. These mass values exceed the best up-to-day known constraints from Fermi gamma observations: 40 GeV and 19 GeV respectively [A.Geringer-Sameth and S.M.Koushiappas, Phys. Rev. Lett. 107, 241303 (2011)]. Precise measurements of the magnetic field in the relevant region and better reconstruction of the DM density profile of M31 will be able to reduce the uncertainties of our exclusion limits.

Evidence for the Tidal Destruction of Hot Jupiters by Subgiant Stars

description: Tidal transfer of angular momentum is expected to cause hot Jupiters to spiral into their host stars. Although the timescale for orbital decay is very uncertain, it should be faster for systems with larger and more evolved stars. Indeed, it is well established that hot Jupiters are found less frequently around subgiant stars than around main-sequence stars. However, the interpretation of this finding has been ambiguous, because the subgiants are also thought to be more massive than the F- and G-type stars that dominate the main-sequence sample. Consequently it has been unclear whether the absence of hot Jupiters is due to tidal destruction, or inhibited formation of those planets around massive stars. Here we show that the Galactic space motions of the planet-hosting subgiant stars demand that on average they be similar in mass to the planet-hosting main-sequence F- and G-type stars. Therefore the two samples are likely to differ only in age, and provide a glimpse of the same exoplanet population both before and after tidal evolution. As a result, the lack of hot Jupiters orbiting subgiants is clear evidence for their tidal destruction. Questions remain, though, about the interpretation of other reported differences between the planet populations around subgiants and main-sequence stars, such as their period and eccentricity distributions and overall occurrence rates.

description: Many day-to-day processes in the manufacturing industry require the use of air compressors that can generate an intermittent or continuous source of pressurized air. Designing, manufacturing and operation of compressor equipment, predetermines a community that includes technical and software tools, as well as personnel that are interconnected within a single system through information, energy and material flows. Carriet out is the analysis of existing approaches to the construction of manufacturing business processes models taking into account functionally oriented control. These processes shall be managed by the organization in accordance with the requirements. The basic principles of process modeling are determined. The method of decision making in the hierarchical structures of the system of enterprise processes is proposed. The results of the theoretical research can be used in the implementation of management systems based on international ISO standards and the description of processes by organizations.

description: Heavy-flavor hadron production studies in Pb-Pb collisions at sqrt(s_{NN}) = 2.76 TeV with the 2010 and 2011 data samples are presented. The measurements are performed with the ALICE detector in various decay channels and in a wide kinematic range. Heavy-flavor hadrons exhibit a suppression in the most central Pb-Pb collisions that amounts to a factor 3-5 for pT ~ 8-10 GeV/c. The second harmonic of the azimuthal distribution Fourier decomposition, v2, is non-zero for non-central collisions at intermediate pT (~3 GeV/c).

description: The method of selection of innovative projects on the rating assessment of their economic efficiency was improved in the course of the study.
This method implies systematization of different orientation of the lighting aspects of economic efficiency of innovative projects of individual indicators and justification of the procedure of generalization of the integral criterion of economic efficiency. Thus, the indicators of economic efficiency of innovative projects have a very narrow direction of application and allow you to compare only the same capital costs of the project. In order to facilitate the comparative evaluation of innovative projects in the paper it is proposed to carry out an integrated assessment, which involves ranking of the projects on the level of individual indicators of economic efficiency. This method makes it possible to comprehensively assess projects of different characteristics, economic sphere, duration of implementation and contains a set of characteristics of the studied projects, which systematically describe the level of economic efficiency.
Generalization of single indicators of economic efficiency of innovative projects is carried out on the basis of a point assessment of level.The scoring is carried out using the "3 Sigma rule", followed by the normal distribution of the data, almost reliably, can be distributed within the average value. This allows you to determine the score and rank of each indicator. The proposed method allows for multi-criteria evaluation of the project to quantitative comparison of individual parameters of different projects and allows you to hide different economic content and units of measurement indicators in a single matter. This allows you to make informed management decisions on investing.

description: Absorption spectra of HD have been recorded in the wavelength range of 75 to 90 nm at 100 K using the vacuum ultraviolet Fourier transform spectrometer at the Synchrotron SOLEIL. The present wavelength resolution represents an order of magnitude improvement over that of previous studies. We present a detailed study of the D^1Π- X^1Σ^+_g system observed up to v'=18. The Q-branch transitions probing levels of Π^- symmetry are observed as narrow resonances limited by the Doppler width at 100 K. Line positions for these transitions are determined to an estimated absolute accuracy of 0.06 cm^{-1} . Predissociation line widths of Π^+ levels are extracted from the absorption spectra. A comparison with the recent results on a study of the D^1Πstate in H_2 and D_2 reveals that the predissociation widths scale as μ^-2J(J+1), with μthe reduced mass of the molecule and J the rotational angular momentum quantum number, as expected from an interaction with the B'^1Σ_u^+ continuum causing the predissociation.

description: Effectively controlling inventory is one of the key factors for small and medium-sized enterprises to make profit. Most small and medium-sized enterprises solve their problems through experience or trial and error, but they are often unable to achieve the desired enterprise performance under limited time and cost. The real case adopted herein covers a manufacturer of optical lens equipment, and the bottleneck is the shortened period of delivery caused by refunded, reduced, and delayed orders due to changes in the market. Under the framework of Lean Six Sigma, this study identified the key factors affecting working hours and product cycle and then formulates strategies to import the actual process. The results show that the inventory turnover rate increases from 20.8% to 41.6%, deriving a financial effect worth of NT$15.57 million. For the practical verification of the case company, Lean Six Sigma really does improve the assembly process efficiency, achieving a result beyond the expected target. With this successful case, this study can be a reference for other firms.

description: High performance computing has been used in various fields of astrophysical research. But most of it is implemented on massively parallel systems (supercomputers) or graphical processing unit clusters. With the advent of multicore processors in the last decade, many serial software codes have been re-implemented in parallel mode to utilize the full potential of these processors. In this paper, we propose parallel processing recipes for multicore machines for astronomical data processing. The target audience are astronomers who are using Python as their preferred scripting language and who may be using PyRAF/IRAF for data processing. Three problems of varied complexity were benchmarked on three different types of multicore processors to demonstrate the benefits, in terms of execution time, of parallelizing data processing tasks. The native multiprocessing module available in Python makes it a relatively trivial task to implement the parallel code. We have also compared the three multiprocessing approaches - Pool/Map, Process/Queue, and Parallel Python. Our test codes are freely available and can be downloaded from our website.

description: We present new long-term CCD photometry for EP And acquired during the period 2007 to 2012. The light curves display total eclipses at primary minima and season-to-season light variability. Our synthesis for all available light curves indicates that the eclipsing pair is a W-type overcontact binary with parameters of q=2.578, i=83.3 deg, $ΔT$=27 K, f=28 %, and l3=2~3 %. The asymmetric light curves in 2007 were satisfactorily modeled by a cool spot on either of the eclipsing components from a magnetic dynamo. Including our 95 timing measurements, a total of 414 times of minimum light spanning about 82 yr were used for a period study. A detailed analysis of the eclipse timing diagram revealed that the orbital period of EP And has varied as a combination of an upward-opening parabola and two periodic variations, with cycle lengths of P3=44.6 yr and P4=1.834 yr and semi-amplitudes of K3=0.0100 d and K4=0.0039 d, respectively. The observed period increase at a fractional rate of +1.39x10^{-10} is in excellent agreement with that calculated from the W-D code and can be plausibly explained by some combination of mass transfer from the primary to the secondary star and angular momentum loss due to magnetic braking. The most reasonable explanation for both cycles is a pair of light-travel-time effects driven by the possible existence of a third and fourth component with projected masses of M3=0.25 Msun and M4=0.90 Msun. The more massive companion could be revealed using high-resolution spectroscopic data extending over the course of a few years and could also be a binary itself. It is possible that the circumbinary objects may have played an important role in the formation and evolution of the eclipsing pair, which would cause it to have a short initial orbital period and thus evolve into an overcontact configuration by angular momentum loss.

description: A comprehensive theory for robust PID control in continuous-time and discrete-time domain is reviewed in this paper. For a given finite set of linear time invariant plants, algorithms for fast computation of robustly stabilizing regions in the ($k_P, k_I, k_D$)-parameter space are introduced. The main impetus is given by the fact that non-convex stable regions in the PID parameter space can be built up by convex polygonal slices. A simple and an elegant theory evolved in the last few years up to a quite mature level.

description: We revisit the implications of naturalness and gauge unification in the MSSM. We find that precision unification of the couplings in connection with a small mu parameter requires a highly compressed gaugino pattern as it is realized in mirage mediation. Due to the small mass difference between gluino and LSP, collider limits on the gluino mass are drastically relaxed. Without further assumptions, the relic density of the LSP is very close to the observed dark matter density due to coannihilation effects.

title: The impact of executive functioning on the mathematics achievement of autistic adolescents
Creators: name: Eddy, Nicole R.A.
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Executive Function (EF) involves the neurological processes behind how we organize environmental information, plan, and direct behaviour. EF components have been found to be related to mathematical performance in the general population. Autistic individuals often experience challenges with their executive functioning– what is referred to as “executive dysfunction”. Additionally, autistic individuals display a widespread pattern of mathematics achievement, with below and above IQ-expected performance, and are significantly more likely to be diagnosed with a math-based learning disability than the general population. The present study explored the relationship of EF and math performance in an autistic youth (around 12-18 years old) sample as compared to a non-autistic sample. Twenty autistic and 34 non-autistic individuals participated in individual remote, online, and synchronous testing sessions in which they completed a battery of measures– including an intellectual ability assessment, fractional (procedural and conceptual) and operational math measures, and EF component tasks. Results from a series of hierarchical linear regressions indicated that the only significant group difference in math skills was found for the fractional procedural math measure; however, none of the EF component task scores were able to account for this difference. This suggests that EF may not exert the same degree of influence on autistic math performance as it does for the general population; however, the small sample size acquired for this study largely limits the statistical power and scope of the results. Future research should explore other possible predictors of math performance in autistic samples.

In the framework of the Hirota direct approach, we present equations describing this model as a system of bilinear equations that belongs to the Ablowitz-Ladik hierarchy. Using the Jacobi-like determinantal identities and the Fay identity for the theta-functions, we derive its Toeplitz, dark-soliton and quasiperiodic solutions as well as the similar set of solutions for the two-dimensional Volterra chain.

description: In the R&D of the CSNS Drift Tube Linac (DTL), the first unit tank with 28 drift tubes has been developed. The axial accelerating field is ramped from 2.2MV/m to 3.1MV/m in this tank. The required field flatness is less than 2 % with the standard deviation of 1 % for the beam dynamics. And the field stability should be less than 1% for machine stable operation. After the successful alignment, the RF tuning was carried out focusing on the field profile measurement. Four slug tuners and 11 post couplers were applied in this procedure. The ramped filed and required stability had been achieved by fine adjustment of the slug tuners and post couplers. In this paper, the preliminary tuning results are presented and discussed.

description: The D^1Π_u - X^1Σ_g^+ absorption system of molecular deuterium has been re-investigated using the VUV Fourier -Transform (FT) spectrometer at the DESIRS beamline of the synchrotron SOLEIL and photon-induced fluorescence spectrometry (PIFS) using the 10 m normal incidence monochromator at the synchrotron BESSY II. Using the FT spectrometer absorption spectra in the range 72 - 82 nm were recorded in quasi static gas at 100 K and in a free flowing jet at a spectroscopic resolution of 0.50 and 0.20 cm^{-1} respectively . The narrow Q-branch transitions, probing states of Π^- symmetry, were observed up to vibrational level v = 22. The states of Π^+ symmetry, known to be broadened due to predissociation and giving rise to asymmetric Beutler-Fano resonances, were studied up to v = 18. The 10 m normal incidence beamline setup at BESSY II was used to simultaneously record absorption, dissociation, ionization and fluorescence decay channels from which information on the line intensities, predissociated widths, and Fano q-parameters were extracted. R-branch transitions were observed up to v = 23 for J = 1-3 as well as several transitions for J = 4 and 5 up to v = 22 and 18 respectively. The Q-branch transitions are found to weakly predissociate and were observed from v = 8 to the final vibrational level of the state v = 23. The spectroscopic study is supported by two theoretical frameworks. Results on the Π^- symmetry states are compared to ab initio multi-channel-quantum defect theory (MQDT) calculations, demonstrating that these calculations are accurate to within 0.5 cm^-1.

Magnesium Isotope Ratios in omega Centauri Red Giants

description: We have used high resolution observations obtained at the AAT with UHRF (R ~ 100,000) and at Gemini-S with b-HROS (R ~ 150,000) to determine magnesium isotope ratios for seven omega Centauri red giants that cover a range in iron abundance from [Fe/H] = --1.78 to --0.78 dex, and for two red giants in M4 (NGC 6121). The omega Centauri stars sample both the "primordial" (i.e., O-rich, Na and Al-poor) and the "extreme" (O-depleted, Na and Al-rich) populations in the cluster. The primordial population stars in both omega Centauri and M4 show (25Mg, 26Mg)/24 Mg isotopic ratios that are consistent with those found for the primordial population in other globular clusters with similar [Fe/H] values. The isotopic ratios for the omega Centauri extreme stars are also consistent with those for extreme population stars in other clusters. The results for the extreme population stars studied indicate that the 26Mg/24Mg ratio is highest at intermediate metallicities ([Fe/H] < --1.4 dex), and for the highest [Al/Fe] values. Further, the relative abundance of 26Mg in the extreme population stars is notably higher than that of 25Mg, in contrast to model predictions. The 25Mg/24Mg isotopic ratio in fact does not show any obvious dependence on either [Fe/H] or [Al/Fe] nor, intriguingly, any obvious difference between the primordial and extreme population stars.

description: We present a detailed investigation of the dynamics of two physically different qubit models, dephasing under the effect of an ultracold atomic gas in a Bose-Einstein condensed (BEC) state. We study the robustness of each qubit probe against environmental noise; even though the two models appear very similar at a first glance, we demonstrate that they decohere in a strikingly different way. This result holds significance for studies of reservoir engineering as well as for using the qubits as quantum probes of the ultracold gas. For each model we study whether and when, upon suitable manipulation of the BEC, the dynamics of the qubit can be described by a (non-)Markovian process and consider the the effect of thermal fluctuations on the qubit dynamics. Finally, we provide an intuitive explanation for the phenomena we observe in terms of the spectral density function of the environment.

description: One of the objectives of the CoRoT mission is the search for transiting extrasolar planets using high-precision photometry, and the accurate characterization of their fundamental parameters. The CoRoT satellite consecutively observes crowded stellar fields since February 2007, in high-cadence precise photometry; periodic eclipses are detected and analysed in the stellar light curves. Then complementary observations using ground-based facilities allows establishing the nature of the transiting body and its mass. CoRoT has acquired more than 163,000 light curves and detected about 500 planet candidates. A fraction of them (5%) are confirmed planets whose masses are independently measured. Main highlights of the CoRoT discoveries are: i) the variety of internal structures in close-in giant planets, ii) the characterisation of the first known transiting rocky planet, CoRoT-7 b, iii) multiple constraints on the formation, evolution, role of tides in planetary systems.

description: La luz milimétrica y submilimétrica nos proporciona una valiosa herramienta para el estudio del Universo y de nuestros orígenes cósmicos. Gracias a ella hemos podido ser testigos de los procesos de formación de exoplanetas y de posibles exolunas, hemos obtenido la primera imagen de un agujero negro o se ha desarrollado enormemente la astroquímica de nuestro sistema solar, nuestra Galaxia y más allá. La lista de hitos seguirá engordando con la llegada de los próximos observatorios, ahora en fase de planificación, como es el caso de AtLAST.En este coloquio introduciré los ingredientes necesarios para hacer realidad tales observaciones. Hablaré de observatorios submilimétricos existentes y futuros, de las peculiaridades de su instrumentación, de los remotos lugares en que se sitúan pero también de las personas que los operan y utilizan.Alrededor de estos observatorios entrecruzan sus caminos diferentes ramas de la Física y de la ingeniería, y pueden ser una enriquecedora experiencia laboral no siempre suficientemente considerada. Por ello quisiera invitar a asistir a todas y todos los estudiantes de los diferentes grados e itinerarios de nuestra Facultad.

description: We investigate the unpolarized pion and kaon fragmentation functions using the nonlocal chiral-quark model. In this model the interactions between the quarks and pseudoscalar mesons is manifested nonlocally. In addition, the explicit flavor SU(3) symmetry breaking effect is taken into account in terms of the current quark masses. The results of our model are evaluated to higher $Q^2$ value $Q^2=4\,\mathrm{GeV}^2$ by the DGLAP evolution. Then we compare them with the empirical parametrizations. We find that our results are in relatively good agreement with the empirical parametrizations and the other theoretical estimations.
