A hybrid technology for parallel recording of single ion channels
Creators: name: Thei, Federico <1976>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: ING-INF/01 Elettronica

description: Hybrid technologies, thanks to the convergence of integrated microelectronic devices and new class of microfluidic structures could open new perspectives to the way how nanoscale events are discovered, monitored and controlled. The key point of this thesis is to evaluate the impact of such an approach into applications of ion-channel High Throughput Screening (HTS)platforms. This approach offers promising opportunities for the development of new classes of sensitive, reliable and cheap sensors. There are numerous advantages of embedding microelectronic readout structures strictly coupled to sensing elements. On the one hand the
signal-to-noise-ratio is increased as a result of scaling. On the other, the readout miniaturization allows organization of sensors into arrays, increasing the capability of the platform in terms of number of acquired data, as required in the HTS approach, to improve sensing accuracy and reliabiity. However, accurate interface design is required to establish efficient communication between ionic-based and electronic-based signals. The work made in this thesis will show a first example of a complete parallel readout system with single ion channel resolution, using a compact and scalable hybrid architecture suitable to be interfaced to large array of sensors, ensuring simultaneous signal recording and smart control of the signal-to-noise ratio and bandwidth trade off. More specifically, an array of microfluidic polymer structures, hosting artificial lipid bilayers blocks where single ion channel pores are embededed, is coupled with an array of ultra-low noise current amplifiers for signal amplification and data processing. As demonstrating working example, the platform was used to acquire ultra small currents derived by single non-covalent molecular binding between alpha-hemolysin pores and beta-cyclodextrin molecules in artificial lipid membranes.
Le determinanti degli investimenti diretti esteri in Italia nel settore agroalimentare

description: Gli investimenti diretti esteri (IDE) giocano un ruolo importante nella crescita
economica e nello sviluppo territoriale. Con il notevole aumento dei flussi IDE nel
settore agroalimentare a livello mondiale l’attenzione si è concentrata sul dibattito
relativo alle determinanti che spingono alla scelta di un territorio piuttosto che un
altro.
Non esiste ancora un lavoro definitivo ed univoco sulle determinanti degli IDE.
Alcune delle più frequenti analisi sui fattori che influenzano gli IDE includono:
l’entità del mercato, il costo del lavoro, i tassi di interesse, le barriere
protezionistiche, tassi di cambio, predisposizione all’export, struttura del mercato,
distanze geografiche, stabilità politica e affinità culturale.
Questo lavoro si propone di analizzare le determinanti nel settore agroalimentare
italiano sia teoricamente che empiricamente. A questo scopo è stata applica come
base teorica il paradigma OLI di Dunning e i principi legati agli investimenti
orizzontali al settore agroalimentare regionale italiano. Sono state esaminate le
determinanti degli investimenti diretti inward in questo settore.
Le risultanti suggeriscono una relazione positiva tra la presenza di attività di servizi
e la presenza di IDE nelle diverse Regioni. In un Paese ad economia avanzata come
l’Italia, strategie territoriali e di impresa basate sui costi e sul mercato non sono
caratterizzanti per attrarre multinazionali straniere, mentre la dotazione di servizi e
infrastrutture rappresentano un nuovo obiettivo su cui le Regioni devono puntare
per aprire i territori alle sfide della globalizzazione.
Questa ricerca unisce analisi statistica ed econometria e studio bibliografico per
approfondire e comprendere la materia in oggetto e fornire nuovi elementi e spunti
su cui discutere.
Ages and Masses of Star Clusters in M33: a Multi-wavelength Study

description: We combine archival images for the nearby galaxy M33 (Triangulum Galaxy) from the ultraviolet (UV) to the infrared (IR) to derive ages, masses, and extinctions for the young star cluster population, and compare our physical parameters with published ones. Our goal is to test the robustness of clusters' ages and masses, and possibly improve on existing ones both by expanding the wavelength range of the spectral energy distribution (SED) fits and by using more recent population synthesis models. The rationale for this experiment is to verify the sensitivity of the clusters' physical parameters to observational setups and model choices that span those commonly found in the literature. We derive the physical parameters of 137 clusters, using SEDs measured in eight UV-to-I bands, including H-alpha, from GALEX and ground-based images. We also add the 24 micron image from the Spitzer Space Telescope to help break some age degeneracies. We find that our derived cluster ages show significant differences with earlier determinations, while the masses remain relatively insensitive to the fitting approach adopted. We also highlight an already known difficulty in recovering old, low-extinction clusters, as SED fitting codes tend to prefer younger, higher extinction solutions when the extinction is a free parameter. We publish updated ages, masses, and extinctions, with uncertainties, for all sample star clusters, together with their photometry; given the proximity of M33, this represents an important population to secure for the study of star formation and cluster evolution in spirals.

description: We study the unique 6 dimensional orbifold with chiral fermions where a stable dark matter candidate is present due to Lorentz invariance on the orbifold, with no additional discrete symmetries imposed by hand. We propose a model of Universal Extra Dimensions where a scalar photon of few hundred GeV is a good candidate for dark matter. The spectrum of the model is characteristic of the geometry, and it has clear distinctive features compared to previous models of Kaluza-Klein dark matter. The 5 dimensional limit of this model is the minimal model of natural Kaluza-Klein dark matter. Notwithstanding the low mass range preferred by cosmology, the model will be a challenge for the LHC due to the relatively small splitting between the states in the same KK level.

description: The generation of nanoscale square and stripe patterns is of major technological importance since they are compatible with industry-standard electronic circuitry. Recently, a blend of diblock copolymer interacting via hydrogen-bonding was shown to self-assemble in square arrays. Motivated by those experiments we study, using Monte Carlo simulations, the pattern formation in a two-dimensional binary mixture of colloidal particles interacting via isotropic core-corona potentials. We find a rich variety of patterns that can be grouped mainly in aggregates that self-assemble in regular square lattices or in alternate strips. Other morphologies observed include colloidal corrals that are potentially useful as surface templating agents. This work shows the unexpected versatility of this simple model to produce a variety of patterns with high technological potential.

description: Planets between 1-4 Earth radii with orbital periods <100 days are strikingly common. The migration model proposes that super-Earths migrate inwards and pile up at the disk inner edge in chains of mean motion resonances. After gas disk dispersal, simulations show that super-Earth's gravitational interactions can naturally break their resonant configuration leading to a late phase of giant impacts. The instability phase is key to matching the orbital spacing of observed systems. Yet, most previous simulations have modelled collisions as perfect accretion events, ignoring fragmentation. In this work, we investigate the impact of imperfect accretion on the breaking the chains scenario. We performed N-body simulations starting from distributions of planetary embryos and modelling the effects of pebble accretion and migration in the gas disk. Our simulations also follow the long-term dynamical evolution of super-Earths after the gas disk dissipation. We compared the results of simulations where collisions are treated as perfect merging events with those where imperfect accretion and fragmentation are allowed. We concluded that the perfect accretion is a suitable approximation in this regime, from a dynamical point of view. Although fragmentation events are common, only ~10% of the system mass is fragmented during a typical "late instability phase", with fragments being mostly reacreted by surviving planets. This limited total mass in fragments proved to be insufficient to alter qualitatively the final system dynamical configuration -- e.g. promote strong dynamical friction or residual migration -- compared to simulations where fragmentation is neglected.

description: Recent observations have shown that a large portion of the mid--infrared (MIR) spectrum of active galactic nuclei (AGN) stems from the polar regions. In this paper, we investigate the effects of this polar gas on the X-ray spectrum of AGN using ray-tracing simulations. Two geometries for the polar gas are considered, (1) a hollow cone corresponding to the best fit MIR model and (2) a filled cone, both with varying column densities (ranging from $10^{21}-10^{22.5}$ cm$^{-2}$) along with a torus surrounding the central X-ray source. We find that the polar gas leads to an increase in the equivalent width of several fluorescence lines below $5$ keV (e.g., O, Ne, Mg, Si). A filled geometry is unlikely for the polar component, as the X-ray spectra of many Type 1 AGN would show signatures of obscuration. We also consider extra emission from the narrow line region such as a scattered power-law with many photoionised lines from obscured AGNs, and different opening angles and matter compositions for the hollow cone. These simulations will provide a fundamental benchmark for current and future high spectral resolution X-ray instruments, such as those on board XRISM and Athena.

description: Today, Internet becomes the essential part of our lives. Over 90 percent of the ecommerce is developed on the Internet. A security algorithm became very necessary for producer client transactions assurance and the financial applications safety. The rsa algorithm applicability derives from algorithm properties like confidentiality, safe authentication, data safety and integrity on the internet. Thus, this kind of networks can have a more easy utilization by practical accessing from short, medium, even long distance and from different public places. Rsa encryption in the client side is relatively cheap, whereas, the corresponding decryption in the server side is expensive because its private exponent is much larger. Thus ssl tls servers become swamped to perform public key decryption operations when the simultaneous requests increase quickly .The batch rsa method is useful for such highly loaded web server .In our proposed algorithm by reducing the response time and clients tolerable waiting time an improvement in performance of ssl tls servers can be done. The proposed algorithm should provide the reasonable response time and optimizes server performance significantly. At Encryption side, to withstand many attacks like brute force attack, subtle attack etc. we also adapted a parameter generation method, which sieve all the parameters strictly, and filter out every insecure parameter.

description: As the possible progenitors of passive galaxies at z=2-3, dusty star-forming galaxies (DSFGs) at z>4 provide a unique perspective to study the formation, assembly, and early quenching of massive galaxies in the early Universe. The extreme obscuration in optical-IR makes (sub)mm spectral scans the most universal and unbiased way to confirm/exclude the high-z nature of candidate dusty star-forming galaxies. We present here the status of the NIKA2 Cosmological Legacy Survey (N2CLS), which is the deepest wide-area single-dish survey in the millimeter searching for high-z DSFGs. We also introduce a joint-analysis method to efficiently search for the spectroscopic redshift of high-z DSFGs with noisy spectra and photometric data and present its success in identifying the redshift of DSFGs found in NIKA2 science verification data.

description: We look at discovering the impact of market microstructure on equitability for market participants at public exchanges such as the New York Stock Exchange or NASDAQ. Are these environments equitable venues for low-frequency participants (such as retail investors)? In particular, can market makers contribute to equitability for these agents? We use a simulator to assess the effect a market marker can have on equality of outcomes for consumer or retail traders by adjusting its parameters. Upon numerically quantifying market equitability by the entropy of the price returns distribution of consumer agents, we demonstrate that market makers indeed support equitability and that a negative correlation is observed between the profits of the market maker and equitability. We then use multi objective reinforcement learning to concurrently optimize for the two objectives of consumer agent equitability and market maker profitability, which leads us to learn policies that facilitate lower market volatility and tighter spreads for comparable profit levels.
Mechanical seed extraction of lodgepole pine
Creators: name: MacAulay, James Donald
Publisher: name: University of British Columbia
Year: 2010

description: Seed extraction from serotinous lodgepole pine cones (Pinus contorta var. latifolia Englem.) was investigated to identify the physical properties and characteristics which affect seed extraction by both conventional kiln drying techniques and by mechanical means. This information provided a basis for systematic design of specific processing tools for a portable continuous flow mechanical seed extraction system. Cone scale deflection was characterized and its effect on seed release is reported. The effect of moisture content upon scale stress relaxation during storage and subsequent reduction in seed release is discussed. Flash heating of cones in hot water and hot gas was found to effectively release serotinous seals without incurring thermal seed damage. Two continuous flow flash heating seal breaking tools were designed and tested. A flame seal breaker proved most suitable for commercial operation, and this tool was calibrated for use on both young and weathered cones. Mechanical seed extraction by cone core removal was effective, but asymmetrical cones prevented accurate core boring, thus resulting in considerable seed destruction. Seed extraction by threshing also was effective. Testing of first and second generation threshing tools was carried out on lodgepole pine, Douglas fir, white spruce and western hemlock. Further study is recommended to identify the optimum values of the many biological variables, machine variables and operating conditions which affect cone threshing.

description: We expect a detectable correlation between two seemingly unrelated quantities: the four point function of the cosmic microwave background (CMB) and the amplitude of flux decrements in quasar (QSO) spectra. The amplitude of CMB convergence in a given direction measures the projected surface density of matter. Measurements of QSO flux decrements trace the small-scale distribution of gas along a given line-of-sight. While the cross-correlation between these two measurements is small for a single line-of-sight, upcoming large surveys should enable its detection. This paper presents analytical estimates for the signal to noise (S/N) for measurements of the cross-correlation between the flux decrement and the convergence and for measurements of the cross-correlation between the variance in flux decrement and the convergence. For the ongoing BOSS (SDSS III) and Planck surveys, we estimate an S/N of 30 and 9.6 for these two correlations. For the proposed BigBOSS and ACTPOL surveys, we estimate an S/N of 130 and 50 respectively. Since the cross-correlation between the variance in flux decrement and the convergence is proportional to the fourth power of $σ_8$, the amplitude of these cross-correlations can potentially be used to measure the amplitude of $σ_8$ at z~2 to 2.5% with BOSS and Planck and even better with future data sets. These measurements have the potential to test alternative theories for dark energy and to constrain the mass of the neutrino. The large potential signal estimated in our analytical calculations motivate tests with non-linear hydrodynamical simulations and analyses of upcoming data sets.

description: Tele-forensic interviewing (tele-FI; e.g., via video-conferencing software) may be an effective way of increasing the accessibility of skilled interviewers for children who are questioned as part of a criminal or care and protection investigation. The current coronavirus disease 2019 (COVID-19) pandemic has highlighted how critical it is that we have evidence-based procedures to draw upon when traditional face-to-face interviews cannot be used. In this article we discuss the benefits and risks associated with tele-FI, review the small number of studies that have examined its effectiveness for eliciting memory reports from adults and children, and discuss practical considerations that should inform planning for an interview. Tele-FI appears a promising avenue for creating resiliency within organizations, and overcoming factors that might otherwise undermine the reliability of children's evidence. Available research indicates children's memory reports elicited in tele-FIs are likely to be as good or better than those from face-to-face interviews, but a more comprehensive evidence-base is needed. Interviewers should be aware of how using this approach may influence their questioning strategies and engagement with children. (PsycInfo Database Record (c) 2021 APA, all rights reserved)

description: We have undertaken a deep, wide-field HI imaging survey of M31, reaching a maximum resolution of about 50 pc and 2 km/s across a 95x48 kpc region. The HI mass and brightness sensitivity at 100 pc resolution for a 25 km/s wide spectral feature is 1500 M_Sun and 0.28 K. Our study reveals ubiquitous HI self-opacity features, discernible in the first instance as filamentary local minima in images of the peak HI brightness temperature. Local minima are organized into complexes of more than kpc length and are particularly associated with the leading edge of spiral arm features. Just as in the Galaxy, there is only patchy correspondence of self-opaque features with CO(1-0) emission. Localized opacity corrections to the column density exceed an order of magnitude in many cases and add globally to a 30% increase in the atomic gas mass over that inferred from the integrated brightness under the usual assumption of negligible self-opacity. Opaque atomic gas first increases from 20 to 60 K in spin temperature with radius to 12 kpc but then declines again to 20 K beyond 25 kpc. We have extended the resolved star formation law down to physical scales more than an order of magnitude smaller in area and mass than has been possible previously. The relation between total-gas-mass- and star-formation-rate-density is significantly tighter than that with molecular-mass and is fully consistent in both slope and normalization with the power law index of 1.56 found in the molecule-dominated disk of M51 at 500 pc resolution. Below a gas-mass-density of about 5 M_Sun/pc^2, there is a down-turn in star-formation-rate-density which may represent a real local threshold for massive star formation at a cloud mass of about 5x10^4 M_Sun.

description: We have implemented an optical quantum eraser with the aim of studying this phenomenon in the context of state discrimination. An interfering single photon is entangled with another one serving as a which-path marker. As a consequence, the visibility of the interference as well as the which-path information are constrained by the overlap (measured by the inner product) between the which-path marker states, which in a more general situation are non-orthogonal. In order to perform which-path or quantum eraser measurements while analyzing non-orthogonal states, we resort to a probabilistic method for the unambiguous modification of the inner product between the two states of the which-path marker in a discrimination-like process.

description: Children often answer questions when they do not have the requisite knowledge or when they do not understand them. We examined whether ground rules instruction-to say "I don't know," to tell the truth, and to correct the interviewer when necessary-assisted children in applying those rules during an interview about a past event and whether doing so was associated with more accurate accounts. We compared children with intellectual disabilities (mild or moderate severity, n = 44, 7-12 years) with 3 groups of typically developing children (2 matched for mental age, and 1 for chronological age, n = 55, 4-12 years) on their understanding of 3 ground rules, their use of these rules in an interview, and their accuracy in recalling a personally experienced event. Many children were able to demonstrate proficiency with the rules following simple instruction but others required additional teaching. Children applied the rules sparingly in the interview. Their scores on the practice trials of each rule were unrelated to each other, and to the use of the rules in context. Their developmental level was significantly related to both of these skills. Regression models showed that developmental level was the best predictor of children's accuracy when they recounted their experience during the interview but that use of responses consistent with the rules, in conjunction with developmental level, predicted accurate resistance to suggestive questions. Future research should identify how best to prepare children of different ages and cognitive abilities to answer adults' questions appropriately.

description: Atlantic Multidecadal Variability (AMV) describes variations of North Atlantic sea surface temperature with a typical cycle of between 60 and 70 years. AMV strongly impacts local climate over North America and Europe, therefore prediction of AMV, especially the extreme values, is of great societal utility for understanding and responding to regional climate change. This work tests multiple machine learning models to improve the state of AMV prediction from maps of sea surface temperature, salinity, and sea level pressure in the North Atlantic region. We use data from the Community Earth System Model 1 Large Ensemble Project, a state-of-the-art climate model with 3,440 years of data. Our results demonstrate that all of the models we use outperform the traditional persistence forecast baseline. Predicting the AMV is important for identifying future extreme temperatures and precipitation, as well as hurricane activity, in Europe and North America up to 25 years in advance.

description: In this paper, we report our latest research on a novel theoretical information-geometric framework suitable to characterize chaotic dynamical behavior of arbitrary complex systems on curved statistical manifolds. Specifically, an information-geometric analogue of the Zurek-Paz quantum chaos criterion of linear entropy growth and an information-geometric characterization of chaotic (integrable) energy level statistics of a quantum antiferromagnetic Ising spin chain in a tilted (transverse) external magnetic field are presented.

description: We are conducting a long-term photometric survey of the nearby galaxy M33 to discover Cepheids, eclipsing binaries, and long-period variables. The dataset combines previously-obtained optical images from the DIRECT project with new observations acquired at the WIYN 3.5m telescope. The entire data set spans over 7 years with excellent synoptic coverage which will enable the discovery and characterization of stars displaying variability over a wide range of timescales (days, weeks, months, years). In this preliminary work we show representative light curves of different variables we found so far in two fields, color-magnitude diagrams, and optical Cepheid Period-Luminosity relations for M33. The ultimate goal of the project is to provide an absolute calibration of the Cepheid Period-Luminosity relation, and to study its metallicity dependence at optical wavelengths.

description: The Biogeochemical-Argo (BGC-Argo) program is building a network of globally distributed, sensor-equipped robotic profiling floats, improving our understanding of the climate system and how it is changing. These floats, however, are limited in the number of variables measured. In this study, we train neural networks to predict silicate and phosphate values in the Southern Ocean from temperature, pressure, salinity, oxygen, nitrate, and location and apply these models to earth system model (ESM) and BGC-Argo data to expand the utility of this ocean observation network. We trained our neural networks on observations from the Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP) and use dropout regularization to provide uncertainty bounds around our predicted values. Our neural network significantly improves upon linear regression but shows variable levels of uncertainty across the ranges of predicted variables. We explore the generalization of our estimators to test data outside our training distribution from both ESM and BGC-Argo data. Our use of out-of-distribution test data to examine shifts in biogeochemical parameters and calculate uncertainty bounds around estimates advance the state-of-the-art in oceanographic data and climate monitoring. We make our data and code publicly available.

Composite system for estimating tree taper and merchantable volume
Creators: name: Segaran, Sandy
Publisher: name: University of British Columbia
Year: 2010

description: A composite system for estimating taper and merchantable volume up to 5 inches top diameter is described for plantation grown trees of Eucalyptus robusta over the D[sub 4.5] range of 10 to 24 inches and heights of 73 to 122 feet. The stem profile could be described by the model g = a - bh where g is the sectional area in square feet at sectional height h feet, a is the regression constant and b the regression coefficient. Relations are derived between the easily measured tree parameters of diameter at breast height (D[sub 4.5]), diameter at 10 feet high (D₁₀) and total height (H) with both a and b. As a result, the regression coefficient b, which is a measure of taper, varies directly as the square of the diameter at breast height, the product of the diameter at breast height and total height, as well as, the product of the square of the diameter at breast height and total height. Various formulae are summarised to derive the standing volumes for desired heights or nominated diameters, and diameters at specific heights or vice versa, and collated in Section 8. The relations of a on H, b on H and form factor for total volume (Fv by D[sub 4.5] classes, are graphed and inferences are drawn. Bias in height or diameter estimation is small, similar for each class and not substantial. Further the height bias is in opposite sign to diameter bias. Bias, in estimating merchantable volumes to 5 inches top diameter by the taper model, as compared with that of the volume model for merchantable volume is small and negligible. The overall bias for the sample trees is 0.16 cubic feet, that is, 0.13 per cent of the total sample merchantable volume estimated by the taper model. For the range of basic data investigated, this taper model was found to adequately describe the stem profile.
