description: The LiHo$_x$Y$_{1-x}$F$_4$ Ising magnetic material subject to a magnetic field, $B_x$, perpendicular to the Ho$^{3+}$ Ising direction has shown over the past twenty years to be a host of very interesting thermodynamic and magnetic phenomena. Unfortunately, the availability of other magnetic materials other than LiHo$_x$Y$_{1-x}$F$_4$ that may be described by a transverse field Ising model remains very much limited. It is in this context that we use here mean-field theory to investigate the suitability of the Ho(OH)$_{3}$, Dy(OH)$_{3}$ and Tb(OH)$_3$ insulating hexagonal dipolar Ising-like ferromagnets for the study of the quantum phase transition induced by a magnetic field, $B_x$, applied perpendicular to the Ising spin direction. From our calculations we estimate the critical transverse field, $B_{x}^{c}$, to destroy ferromagnetic order at zero temperature to be $B_{x}^{c}=$4.35 T, $B_{x}^{c}=$5.03 T and $B_{x}^{c}=$54.81 T for Ho(OH)$_{3}$, Dy(OH)$_{3}$ and Tb(OH)$_{3}$, respectively. We conclude from our calculations that Ho(OH)$_{3}$ and Dy(OH)$_{3}$, and their Y$^{3+}$ diamagnetically diluted variants, Ho$_{x}$Y$_{1-x}$(OH)$_{3}$ and Dy$_{x}$Y$_{1-x}$(OH)$_{3}$, are potentially interesting systems to study transverse-field induced quantum fluctuations effects in hard axis (Ising-like) magnetic materials.

description: We investigated metal-insulator transitions for double layer two-dimensional electron hole systems in transition metal dicalcogenides (TMDC) stacked on opposite sides of thin layers of boron nitride (BN). The interparticle interaction is calculated by including the screening due to the polarization charges at different interfaces, including that at the encapsultion and the substrate of experimental structures. We compute and compare the energies of the metallic electron-hole plasma and the newly proposed insulating exciton solid with fixed-node diffusion Monte Carlo simulation including the high valley degeneracy of the electron bands. We found that for some examples of current experimental structures, the transition electron/hole density is in an accessible range of g x 10^12 /cm*2 with g between 4.1 and 14.5 for spacer thicknesses between 2.5 and 7.5 nm. Our result raise the possibility of exploiting this effect for logic device applications.

description: The resonator-induced phase gate is a two-qubit operation in which driving a bus resonator induces a state-dependent phase shift on the qubits equivalent to an effective $ZZ$ interaction. In principle, the dispersive nature of the gate offers flexibility for qubit parameters. However, the drive can cause resonator and qubit leakage, the physics of which cannot be fully captured using either the existing Jaynes-Cummings or Kerr models. In this paper, we adopt an ab-initio model based on Josephson nonlinearity for transmon qubits. The ab-initio analysis agrees well with the Kerr model in terms of capturing the effective $ZZ$ interaction in the weak-drive dispersive regime. In addition, however, it reveals numerous leakage transitions involving high-excitation qubit states. We analyze the physics behind such novel leakage channels, demonstrate the connection with specific qubits-resonator frequency collisions, and lay out a plan towards device parameter optimization. We show this type of leakage can be substantially suppressed using very weakly anharmonic transmons. In particular, weaker qubit anharmonicity mitigates both collision density and leakage amplitude, while larger qubit frequency moves the collisions to occur only at large anharmonicity not relevant to experiment. Our work is broadly applicable to the physics of weakly anharmonic transmon qubits coupled to linear resonators. In particular, our analysis confirms and generalizes the measurement-induced state transitions noted in Sank et al. (Phys. Rev. Lett. 117, 190503) and lays the groundwork for both strong-drive resonator-induced phase gate implementation and strong-drive dispersive qubit measurement.

Subjects: AGR/03 Arboricoltura generale e coltivazioni arboree

description: During the last decade peach and nectarine fruit have lost considerable market share, due to increased consumer dissatisfaction with quality at retail markets. This is mainly due to harvesting of too immature fruit and high ripening heterogeneity. The main problem is that the traditional used maturity indexes are not able to objectively detect fruit maturity stage, neither the variability present in the field, leading to a difficult post-harvest management of the product and to high fruit losses. To assess more precisely the fruit ripening other techniques and devices can be used. Recently, a new non-destructive maturity index, based on the vis-NIR technology, the Index of Absorbance Difference (IAD), that correlates with fruit degreening and ethylene production, was introduced and the IAD was used to study peach and nectarine fruit ripening from the “field to the fork”. In order to choose the best techniques to improve fruit quality, a detailed description of the tree structure, of fruit distribution and ripening evolution on the tree was faced. More in details, an architectural model (PlantToon®) was used to design the tree structure and the IAD was applied to characterize the maturity stage of each fruit. Their combined use provided an objective and precise evaluation of the fruit ripening variability, related to different training systems, crop load, fruit exposure and internal temperature. Based on simple field assessment of fruit maturity (as IAD) and growth, a model for an early prediction of harvest date and yield, was developed and validated. The relationship between the non-destructive maturity IAD, and the fruit shelf-life, was also confirmed. Finally the obtained results were validated by consumer test: the  fruit sorted in different maturity classes obtained a different consumer acceptance. The improved knowledge, leaded to an innovative management of peach and nectarine fruit, from  “field to market”.

description: Future wireless communications systems are expected to be extremely dynamic, smart and capable to interact with the surrounding radio environment. To implement such advanced devices, cognitive radio (CR) is a promising paradigm, focusing on strategies for acquiring information and learning. The first task of a cognitive systems is spectrum sensing, that has been mainly studied in the context of opportunistic spectrum access, in which cognitive nodes must implement signal detection techniques to identify unused bands for transmission.
In the present work, we study different spectrum sensing algorithms, focusing on their statistical description and evaluation of the detection performance. Moving from traditional sensing approaches we consider the presence of practical impairments, and analyze algorithm design. Far from the ambition of cover the broad spectrum of spectrum sensing, we aim at providing contributions to the main classes of sensing techniques. In particular, in the context of energy detection we studied the practical design of the test, considering the case in which the noise power is estimated at the receiver. This analysis allows to deepen the phenomenon of the SNR wall, providing the conditions for its existence and showing that presence of the SNR wall is determined by the accuracy of the noise power estimation process. In the context of the eigenvalue based detectors, that can be adopted by multiple sensors systems, we studied the practical situation in presence of unbalances in the noise power at the receivers. Then, we shift the focus from single band detectors to wideband sensing, proposing a new approach based on information theoretic criteria. This technique is blind and, requiring no threshold setting, can be adopted even if the statistical distribution of the observed data in not known exactly. In the last part of the thesis we analyze some simple cooperative localization techniques based on weighted centroid strategies.

description: Social media platforms are thriving nowadays, so a huge volume of data is produced. As it includes brief and clear statements, millions of people post their thoughts on microblogging sites every day. This paper represents and analyze the capacity of diverse strategies to volumetric, delicate, and social networks to predict critical opinions from online social networking sites. In the exploration of certain searching for relevant, the thoughts of people play a crucial role. Social media becomes a good outlet since the last decades to share the opinions globally. Sentiment analysis as well as opinion mining is a tool that is used to extract the opinions or thoughts of the common public. An occurrence in one place, be it economic, political, or social, may trigger large-scale chain public reaction across many other sites in an increasingly interconnected world. This study demonstrates the evaluation of sentiment analysis techniques using social media contents and creating the association between subjectivity with herd behavior and clustering coefficient as well as tries to predict the election result (2021 election in West Bengal). This is an implementation of sentiment analysis targeted at estimating the results of an upcoming election by assessing the public's opinion across social media. This paper also has a short discussion section on the usefulness of the idea in other fields.

description: We study the matter density fluctuations in the running cosmological constant (RCC) model using linear perturbations in the longitudinal gauge. Using this observable we calculate the growth rate of structures and the matter power spectrum, and compare them with the $SDSS$ data and other available data of the linear growth rate. The distribution of collapsed structures may also constraints models of dark energy. It is shown that RCC model enhances departures from the $ΛCDM$ model for both cluster number and cumulative cluster number predicted. In general increasing the characteristic parameter $ν$ leads to significant growth of the cluster number. In general, we found that the theory of perturbations provides a good tool to distinguish the new model $RCC$ of the standard cosmological model $ΛCDM$.

description: Electrons on the surface of a strong topological insulator, such as Bi2Te3 or Bi1-xSnx, form a topologically protected helical liquid whose excitation spectrum contains an odd number of massless Dirac fermions. A theoretical survey and classification is given of the universal features, observable by the ordinary and spin-polarized scanning tunneling spectroscopy, in the interference patterns resulting from the quasiparticle scattering by magnetic and non-magnetic impurities in such a helical liquid. Our results confirm the absence of backscattering from non-magnetic impurities observed in recent experiments and predict new interference features, uniquely characteristic of the helical liquid, when the scatterers are magnetic.

description: Thermodynamic and dynamical properties of systems with long-range pairwise interactions (LRI), which decay as $1/r^{d+σ}$ at large distances $r$ in $d$ dimensions, are reviewed. Two broad classes of such systems are discussed. (i) Systems with a slow decay of the interactions, termed "strong" LRI, where the energy is super-extensive. These systems are characterized by unusual properties such as inequivalence of ensembles, negative specific heat, slow decay of correlations, anomalous diffusion and ergodicity breaking. (ii) Systems with faster decay of the interaction potential, where the energy is additive, thus resulting in less dramatic effects. These interactions affect the thermodynamic behavior of systems near phase transitions, where long-range correlations are naturally present. Long-range correlations are often present in systems driven out of equilibrium when the dynamics involves conserved quantities. Steady state properties of driven systems with local dynamics are considered within the framework outlined above.

description: A foundational model has been developed based on trends built from empirical data of space exploration and computing power through the first six plus decades of the Space Age which projects earliest possible launch dates for human-crewed missions from cis-lunar space to selected Solar System and interstellar destinations. The model uses computational power, expressed as transistors per microprocessor, as a key broadly limiting factor for deep space missions' reach and complexity. The goal of this analysis is to provide a projected timeframe for humanity to become a multi-world species through off-world colonization, and in so doing all but guarantees the long-term survival of the human race from natural and human-caused calamities that could befall life on Earth. Be-ginning with the development and deployment of the first nuclear weapons near the end of World War II, humanity entered a 'Window of Peril' which will not be safely closed until robust off-world colonies become a reality. Our findings suggest the first human-crewed missions to land on Mars, selected Asteroid Belt objects, and selected moons of Jupiter and Saturn can occur before the end of the 21st century. Launches of human-crewed interstellar missions to exoplanet destinations within roughly 40 lightyears of the Solar System are seen as possible during the 23rd century and launch of intragalactic missions by the end of the 24th century. An aggressive and sustained space exploration program, which includes colonization, is thus seen as critical to the long-term survival of the human race.

description: Quantitative scanning transmission electron microscopy (STEM) allows composition determination for nanomaterials at an atomic scale. To improve the accuracy of the results obtained, optimized imaging parameters should be chosen for annular dark field imaging. In a simulation study, we investigate the influence of imaging parameters on the accuracy of the composition determination with the example of ternary III-V semiconductors. It is shown that inner and outer detector angles and semi-convergence angle can be optimized, also in dependence on specimen thickness. Both, a minimum sampling of the image and a minimum electron dose are required. These findings are applied experimentally by using a fast pixelated detector to allow free choice of detector angles.

description: Probabilistic timed automata are an extension of timed automata with discrete probability distributions. We consider model-checking algorithms for the subclasses of probabilistic timed automata which have one or two clocks. Firstly, we show that PCTL probabilistic model-checking problems (such as determining whether a set of target states can be reached with probability at least 0.99 regardless of how nondeterminism is resolved) are PTIME-complete for one-clock probabilistic timed automata, and are EXPTIME-complete for probabilistic timed automata with two clocks. Secondly, we show that, for one-clock probabilistic timed automata, the model-checking problem for the probabilistic timed temporal logic PCTL is EXPTIME-complete. However, the model-checking problem for the subclass of PCTL which does not permit both punctual timing bounds, which require the occurrence of an event at an exact time point, and comparisons with probability bounds other than 0 or 1, is PTIME-complete for one-clock probabilistic timed automata.

title: (Re)producing a dignified life. An exploration of the production and negotiation of classed and gendered subjectivities through reproductive practices among pobladora women in Chile
Creators: name: Álvarez-López, Valentina
Publisher: name: Goldsmiths, University of London
Year: 2021

description: This thesis is an ethnographic exploration of the ways in which throughout their lives, mature and elderly pobladora women – women who live in working-class neighbourhoods in Chile – have negotiated classed and gendered positions through practices of social reproduction. It asks: How have pobladora women produced their gendered and classed subjectivities through practices of social reproduction in their positions as mothers, homemakers and/or wives? This research examines the values and the value that pobladora women have attached to the practices that ensure the social reproduction of their households, as well as the work of community organisations that respond to concrete reproductive needs. This, in light of historical configurations of gender and class in Chile. 

This work draws on more than ten months of intensive ethnographic fieldwork conducted between 2014 and 2017 in a working-class neighbourhood called Nuevo Amanecer, whose past and present are critical for the aims of this research. Ethnography with a feminist perspective has been used as both a method for gathering data and a form of writing, including a strong historical component.

The main contribution of this thesis is that, through ethnography, it offers a bridge between different perspectives and theoretical frameworks on class between materialist – in particular Social Reproduction Theory (SRT) – and symbolic/moral approaches to class, which have often been seen as divergent. It also contributes to SRT by stressing the relevance of subjectivity to an understanding of processes of capitalist accumulation and the gendered organisation of social production/reproduction. Furthermore, by providing a more nuanced and less moralised understanding of the effects of class in women’s subjectivities in relation to wage work and care labour than that provided by mainstream feminist approaches, this thesis provides new insights to understand the persistence of social reproduction as gendered labour. It argues that, through the labours of social reproduction, pobladora women have waged symbolic struggles that position themselves and their families as dignified – classed and gendered – subjects.

description: We present a mathematica package that performs the symbolic calculation of integrals of the form \int^{\infty}_0 e^{-x/u} x^n j_ν (x) j_μ (x) dx where $j_ν (x)$ and $j_μ (x)$ denote spherical Bessel functions of integer orders, with $ν\ge 0$ and $μ\ge 0$. With the real parameter $u>0$ and the integer $n$, convergence of the integral requires that $n+ν+μ\ge 0$. The package provides analytical result for the integral in its most simplified form. The novel symbolic method employed enables the calculation of a large number of integrals of the above form in a fraction of the time required for conventional numerical and Mathematica based brute-force methods. We test the accuracy of such analytical expressions by comparing the results with their numerical counterparts.

description: Nuclear regions of galaxies generally host a mixture of components with different exitation, composition, and kinematics. Derivation of emission line ratios and kinematics could then be misleading, if due correction is not made for the limited spatial and spectral resolutions of the observations.The aim of this paper is to demonstrate, with application to a long slit spectrum of the Seyfert 2 galaxy NGC 1358, how line intensities and velocities, together with modelling and knowledge of the point spread function, may be used to resolve the differing structures. In the situation outlined above, the observed kinematics differs for different spectral lines. From the observed intensity and velocity distributions of a number of spectral lines and with some reasonable assumptions to diminish the number of free parameters, the true line ratios and velocity structures may be deduced. A preliminary solution for the nuclear structure of NGC 1358 is obtained, involving a nuclear point source and an emerging outflow of high exitation, as well as a nuclear emission line disk rotating in the potential of a stellar bulge and expressing a radial excitation gradient. The method results in a likely scenario for the nuclear structure of the Seyfert 2 galaxy NGC 1358. For definitive results an extrapolation of the method to two dimensions combined with the use of integral field spectroscopy will generally be necessary.

description: Dust and gas in protoplanetary disks dissipate as central stars evolve. In order to estimate the dust dissipation timescales in the protoplanetary disks, we stacked the WISE 12, 22, and the AKARI 90 $μ$m survey images of known T Tauri stars and derived the average fluxes, well below the survey flux limit in the 90 $μ$m band. We classified 4,783 T Tauri stars into three age groups, which are young ($$6 Myr) groups, and stacked the WISE 12 and 22 and the AKARI 90 $μ$m images in each group. The photometry of the stacked image shows the flux decay timescales of 1.4$\pm$0.2, 1.38$\pm$0.05, and 1.4$^{+0.6}_{-0.5}$ Myr in the 12, 22, and 90 $μ$m bands, respectively. In optically thin disks with one-solar luminosity central stars, the 12 and 22 $μ$m fluxes are attributed to the emission from the intermediate ($\sim$ 1 au) region and the 90 $μ$m flux corresponds to that from the outer ($\sim$ 10 au) region in the disk. We hence conclude the dust dissipation timescale is $τ_{\rm med,dust}\sim$1.4 Myr in the intermediate disks and is $τ_{\rm outer, dust}=$1.4$^{+0.6}_{-0.5}$ Myr in the outer disks. The dust-dissipation time difference between the outer and intermediate disks is $Δτ_{\rm dust} = τ_{\rm outer,dust} -τ_{\rm med,dust}=0.0^{+0.6}_{-0.5}$ Myr, indicating that the dust in the intermediate and outer disks dissipates on almost the same timescale.

description: We report here on the production of an ultracold gas of tightly bound Rb2 molecules in the ro-vibrational triplet ground state, close to quantum degeneracy. This is achieved by optically transferring weakly bound Rb2 molecules to the absolute lowest level of the ground triplet potential with a transfer efficiency of about 90%. The transfer takes place in a 3D optical lattice which traps a sizeable fraction of the tightly bound molecules with a lifetime exceeding 200 ms.

Attached algae as indicators of water quality in phosphorus enriched Kootenay Lake, British Columbia
Creators: name: Ennis, Gordon Leonard
Publisher: name: University of British Columbia
Year: 2010

description: Kootenay Lake receives high phosphorus loads to its south end and low phosphorus loads to its north end. These loading differences, combined with the lake's 105 km long fjord morphology, should result in a regional trophic gradient in the lake. I studied attached algae to assess how well they supplemented nutrient data in providing a more accurate measure of regional water quality differences. Algal abundance, phosphorus storage, production, species composition and distribution were measured at up to 30 locations in the rocky littoral zone of Kootenay Lake. In addition, physical parameters were measured and water samples were analyzed for major nutrients, anions and cations. Loadings of total dissolved solids, calcium, and sodium are also highest to the south end of the lake, and concentration gradients of these biologically conservative elements conform to the expected pattern. On the other hand, dissolved and particulate inshore phosphate readings, although high, did not exhibit regional variations. Attached algae remove large amounts of phosphorus for growth, altering phosphorus concentrations in the lake. Also, attached algae store surplus phosphorus within their cells, more phosphorus being stored in the regions of highest phoshate loadings (over 1.0 μg P mg⁻¹ dry weight algae) than elsewhere. South arm algae had the highest chlorophyll "a" levels, organic weights and production rates. Their results were typical of eutrophic waters. In contrast, north arm algae were less abundant, had lower growth rates, and were typical of mesotrophic and oligotrophic waters. Eutrophic indicator species, such as the green alga Cladophora aegagropila and the diatom Fragilaria construens, were abundant in the south half of the lake and generally absent or less common at other locations. Diatom cluster analyses divided the lake into regions, stations in areas of low phosphate loadings forming groups distinct from stations located near high phosphorus inputs. One must conclude that aqueous phosphorus concentrations, altered by attached algae, are inadequate indicators of Kootenay Lake's trophic gradient. Attached algae do exhibit regional variations consistent with the lake's expected trophic gradient and are therefore good indicators of water quality in phosphorus enriched Kootenay Lake.

description: Texnologik jarayonlar uchun qo‘llaniladigan suvning sifati aylanma tizimlarda mavjud bo‘lgan suvning sifatidan yuqori bo‘lishi lozim. Suvning sifati deganda, uning sanoat korxonasida qo‘llanilishi mumkinligini ta’minlovchi fizik, kimyoviy, biologik va bakteriologik ko‘rsatkichlari majmuasi tushuniladi. Korxonada ishlatilayotgan suvning sifati har bir holatda uning qanday qo‘llanilishiga qarab, qo‘llanilayotgan ashyoning tarkibini, qo‘llanilayotgan uskunalarni nazarda tutgan holda texnologik jarayon talablari, korxonaning tayyor mahsuloti afzalligi orqali belgilanadi. Ammo, yuqoridagi afzalliklarga qaramay, xlorlashning asosiy kamchiligi xlorli organik birikmalar hosil bo‘lishi natijasida, ular juda zaharli, mutagen va kanserogen ta’sir etuvchi moddalar hosil qilib, tub cho‘kindilarda, tuproqda, suvda yashovchi organizmlarning to‘qimalarida to‘planib, ularning fiziologik o‘zgarishlari va o‘limiga sabab bo‘ladi.

description: The quality of water used for technological processes should be higher than the quality of water contained in circulating systems. When we say the quality of water, a complex of physical, chemical, biological and bacteriological indicators is understood, which ensures that it can be used in an industrial enterprise. The quality of water used in the enterprise is determined by the advantage of the enterprise's finished output, the requirements of the technological process, referring to the composition of the Applied Material, the equipment used, depending on how it is used in each case. However, despite the above advantages, the main drawback of chlorination is that as a result of the formation of chlorinated organic compounds, they form highly toxic, mutagenic and carcinogenicogen affecting substances, which accumulate in the tissues of tubular sediments, soil, aquatic organisms, causing their physiological changes and death. Usually it is impossible to neutralize water by 100%. Therefore, it is now accepted to increase the effectiveness of disinfection by 99; in this case, the rate of disinfection of purified water to 99,9% of the number of processed microbes is observed according to the post-treatment in the primary, secondary method.

La carriera degli attori italiani di prosa dalla scena allo schermo (1909-1916)

description: Most actors of the Italian silent cinema in the early 1910s have a theatrical training. Some of them are already asserted or famous actors (like Cesare Dondini, Ermete Novelli, Ermete Zacconi, Giovanni Grasso) who are invited “to pose” for the cinema following their reputation, according to a strategy of an aesthetic and cultural legitimacy launched in 1909 by film d'art of the Pathé Consortium. I think it is the proverbial readiness and strength of the stage Italian actors that create a decisive contribution to the rapid development of the
national cinema industry, despite its serious structural deficiencies, from the protoindustrialized phase (1909) to the golden age of divismo (starting in 1913), until the first signs of decadence (1919), and the so-called “fall” of the UCI production and distribution system.
This is the main topic of the thesis: an investigation on the Italian stage actors engaged in the film industry (“from stage to screen” as the Italian title says, but in a “post-Vardac” approach) through many different sources: periodicals, memories, personal and business letters, and also contracts, found in several archive funds.
A specific chapter is dedicated to the artistic career of Febo Mari (1881-1939), real name Alfredo Rodriguez, witch is a time-sample symptomatic of deep ties established
between the growing film publishing and the Italian theatrical production system in the 1910s. The Mari debut in cinema and his ascent toward screen “divo” status coincides with the parable that leads from emergence to decadence of divismo in Italy.
