description: The past decade has seen a significant growth in research targeted at space based observatories for imaging exo-solar planets. The challenge is in designing an imaging system for high-contrast. Even with a perfect coronagraph that modifies the point spread function to achieve high-contrast, wavefront sensing and control is needed to correct the errors in the optics and generate a "dark hole". The high-contrast imaging laboratory at Princeton University is equipped with two Boston Micromachines Kilo-DMs. We review here an algorithm designed to achieve high-contrast on both sides of the image plane while minimizing the stroke necessary from each deformable mirror (DM). This algorithm uses the first DM to correct for amplitude aberrations and the second DM to create a flat wavefront in the pupil plane. We then show the first results obtained at Princeton with this correction algorithm, and we demonstrate a symmetric dark hole in monochromatic light.
Quantitative analysis of retrovirus-mediated gene transfer into mammalian cells

Publisher: name: University of British Columbia

description: Recombinant retroviruses (gammaretro-, lenti- and foamy-viral vectors) are used for gene therapy as well as for scientific research because of their ability to provide relatively stable gene transfer and expression. The process of retrovirus-mediated gene transfer into mammalian cells involves a series of transduction events that take place sequentially. A mathematical model for the retroviral transduction process was developed that incorporates the important extracellular and intracellular rate-limiting steps. The mathematical model was validated with experimental data obtained using gibbon ape leukemia virus envelope pseudotyped retroviral vectors and K562 target cells. The model predictions of transduction efficiency and integrated virus copy number were generally in good agreement with measured results acquired for both static and centrifugation-based gene transfer protocols. However, a deviation between the model calculations and the experimental transduction efficiency data was observed for centrifugation at high vector-to-cell ratios. To address this limitation, believed to be caused by the saturation of binding sites on the cell surface, a detailed experimental investigation of the binding and entry kinetics of retroviruses was performed. With the help of a mathematical representation for retroviral binding to, dissociation from and entry into mammalian cells, the kinetic rate constants for these three steps were experimentally quantified. The model was modified to incorporate these more complex kinetic steps and was shown to provide even better predictions of the experimental transduction results for the full range of vector-to-cell ratios investigated. The modified model was then used to optimize various retroviral transduction process parameters. Studies of the extracellular transport of viral vectors provided the optimal range of centrifugal forces needed to obtain the maximum transduction efficiency. Based on a simulated performance comparison of the three different types of recombinant retroviruses, lentiviral vectors were found to be very efficient for targeting hematopoietic stem cells. The mathematical model was able to provide a set of conditions where retroviral transduction protocols should yield high transduction efficiencies while maintaining the viral copy number in a lower, more desirable range.

description: Biomedical data commonly include repeated measures of biomarkers and disease states over time. When the processes determining the biomarker levels and disease states are related, a joint longitudinal and survival model is needed to properly handle the data. In a recent study of adrenal cancer patients at the University of Michigan, their tumors were monitored with repeated radiography scans. Other body measurements, called morphomics, were also measured from these scans. At each scan, it was noted whether the patient's disease was stable, progressing or regressing. In addition, the data include time to death or end of follow-up. Motivated by this data we explore joint models for longitudinal and survival data of several types. In Chapter 2 we compare computational approaches to joint longitudinal and survival models with a single type of event. We examine different joint model formulations especially those most often implemented in software available to statisticians and clinicians. We apply and compare several models to the adrenal data and perform a simulation study to further evaluate each model and software. In Chapter 3 we examine the relationship between a morphomic variable and time to first disease state change which can be either cancer progression or regression, in the adrenal cancer data. We develop Bayesian joint models for longitudinal and competing risks survival data. A seldom considered aspect of competing risk joint models is the relationship between the two competing outcomes. This cannot be examined when using the most common technique, cause-specific hazards models. With that motivation for our future projects, we work under the assumption that each risk has a latent failure time for each individual. We begin with the simple case of conditionally independent risks and model the survival times using parametric distributions. We apply our models to the adrenal data and examine the performance via simulations. In Chapter 4 we extend our joint longitudinal and competing risks models for dependent competing risks. We begin with a discussion of survival copulas and the general joint survival function we will use which is based on an Archimedean copula model. We prove that dependent variables with this joint survival function can be written in terms of independent variables which is useful for simulating data. We develop the model with Weibull marginals. We fit this model to the adrenal data and examine the models using a simulation study. We discuss interpretations of the model and how it can be used to learn about the dependence between risks. Finally, in Chapter 5 we will develop a joint model that incorporates multiple longitudinal outcomes and multistate survival data. We will develop an appropriate model and apply it to the adrenal cancer data.

description: Design and synthesis of three novel series of aryl enaminones (3a–f and 5a–c) and pyrazole (4a-c) linked compounds with sulphonamides, sulfaguanidine, or carboxylic acid functionalities were reported as carbonic anhydrase inhibitors (CAIs) using the “tail approach” strategy in their design to achieve the most variable amino acids in the middle/outer rims of the hCAs active site. The synthesised compounds were assessed in vitro for their inhibitory activity against the following human (h) isoforms, hCA I, II, IX, and XII using stopped-flow CO2 hydrase assay. Enaminone sulphonamide derivatives (3a–c) potently inhibited the target tumour-associated isoforms hCA IX and hCA XII (KIs 26.2–63.7 nM) and hence compounds 3a and 3c were further screened for their in vitro cytotoxic activity against MCF-7 and MDA-MB-231 cancer cell lines under normoxic and hypoxic conditions. Derivative 3c showed comparable potency against both MCF-7 and MDA-MB-231 cancer cell lines under both normoxic ((IC50 = 4.918 and 12.27 µM, respectively) and hypoxic (IC50 = 1.689 and 5.898 µM, respectively) conditions compared to the reference drug doxorubicin under normoxic (IC50 = 3.386 and 4.269 µM, respectively) and hypoxic conditions (IC50 = 1.368 and 2.62 µM, respectively). Cell cycle analysis and Annexin V-FITC and propidium iodide double staining methods were performed to reinforce the assumption that 3c may act as a cytotoxic agent through the induction of apoptosis in MCF-7 cancer cells.

description: Dicke model predicts a quantum phase transition from normal to superradiant phases for a two-level atomic ensemble coupled with an optical cavity at zero temperature. In a recent pioneer experiment [Nature 464, 1301 (2010)], such a phase transition has been observed using a Bose-Einstein condensate (BEC) in an optical cavity. Compared with the original Dicke model, the experimental system features finite temperature and strong atom-photon nonlinear interaction in BEC. In this Letter, we develop a finite temperature theory for the Dicke phase transition of a BEC in an optical cavity, taking into account the atom-photon nonlinear interaction. In addition to explaining the experimentally observed transition from normal to superradiant phases at finite-temperature, we point it out that a new phase, the coexistence of normal and superradient phases, was also observed in the experiment. We show rich finite temperature phase diagrams existing in the experimental system by tuning various experimental parameters. We find that the specific heat of the BEC can serve as a powerful tool for probing various phases.

description: The development of spintronics devices over the last 30 years has necessitated study into a large number of unique semiconductors. In the past 8 years, one emerging focus of study has been into two dimensional materials, with a focus on layered Van der Waals materials such as graphene and transition metal dichalcogenides (TMDs). In this dissertation, we utilize optical methods to study the spatial dependence of the spin valley polarization in the monolayer TMD tungsten diselenide (WSe2). When reduced to a single monolayer, TMDs are a direct band gap semiconductor with large spin splitting in both conduction and valence bands. These materials also display valley-dependent optical selection rules, allowing for carefully tuned laser pulses to selectively excite electron and hole spins in one direction. We use time-resolved Kerr rotation and other similar optical methods to excite spin valley polarizations in monolayer MOCVD-grown WSe2 and probe their dynamics. Our Kerr signal reveals bi-exponential decay with time constants of 100 ps and 3 ns. Measurements are repeated on multiple flakes with radii of approximately 9 to 13 micrometers, as well as more continuous sample areas with many overlapping grain boundaries. These measurements also reveal larger spin valley polarizations at the edges of individual flakes than near the centers. Both photoluminescence and reflectivity measurements are also performed on the same flakes, but do not exhibit a similar spatial dependence. In order to perform the measurements described here, a time-resolved Kerr microscopy setup was constructed in our lab. This setup is capable of performing Kerr rotation measurements while varying multiple parameters including pump-probe separation, pump-probe time delay, magnetic field, and spatial position on the sample. The pump and probe spot sizes on the sample using this experimental setup are under 3 microns FWHM, and the pulse width of the laser allows for time delay scans to be taken with 10 ps resolution. I was heavily involved in the assembly and calibration of this experimental setup; as such, its workings and calibration procedures are described in this dissertation. Efforts were also taken to create electrically contacted samples in the Lurie Nanofabrication Facility. Multiple iterations of lithography procedures were performed in order to properly align source and drain contacts across sub-10 micron flakes. Unfortunately, once these devices were fully realized in the clean room, the lift-off procedure for the photoresist caused a significant drop in signal in the samples and therefore complete realization of these devices remains a promising subject of future work.

description: Excerpt from the report: To ascertain the geographical pattern of milk shipments and the quantities of bulk fluid milk being moved over long distances, over 400 plants holding certified ratings for interstate milk shipments were contacted in 1961 and 1962. These were practically all of the plants which might make interstate shipments of milk. All shipments exceeding 200 miles were recorded, except that regular shipments to handlers regulated by the Federal orders for New York-New Jersey and Chicago were excluded regardless of the distance the milk was hauled. Both regular and spot (emergency) shipments during the period September 1, 1960, through August 31, 1961, were recorded. Throughout this report, the data on milk shipments are those reported by these plants.

description: We report the presence of σ-aromaticity in a surface deposited cluster, Pd$_4$ on TiO$_2$ (110). In the gas phase, Pd$_4$ adopts a tetrahedral structure. However, surface binding promotes a flat, σ-aromatic cluster. This is the first time aromaticity is found in surface deposited clusters. Systems of this type emerge as a promising class of catalyst, and so realization of aromaticity in them may help to rationalize their reactivity and catalytic properties, as a function of cluster size and composition.

The New Flavor of Higgsed Gauge Mediation

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Recent LHC bounds on squark masses combined with naturalness and flavor considerations motivate non-trivial sfermion mass spectra in the supersymmetric Standard Model. These can arise if supersymmetry breaking is communicated to the visible sector via new extended gauge symmetries. Such extended symmetries must be spontaneously broken, or confined, complicating the calculation of soft masses. We develop a new formalism for calculating perturbative gauge-mediated two-loop soft masses for gauge groups with arbitrary patterns of spontaneous symmetry breaking, simplifying the framework of "Higgsed gauge mediation." The resulting expressions can be applied to Abelian and non-Abelian gauge groups, opening new avenues for supersymmetric model building. We present a number of examples using our method, ranging from grand unified threshold corrections in standard gauge mediation to soft masses in gauge extensions of the Higgs sector that can raise the Higgs mass through non-decoupling D-terms. We also outline a new mediation mechanism called "flavor mediation", where supersymmetry breaking is communicated via a gauged subgroup of Standard Model flavor symmetries. Flavor mediation can automatically generate suppressed masses for third-generation squarks and implies a nearly exact U(2) symmetry in the first two generations, yielding a "natural SUSY" spectrum without imposing ad hoc global symmetries or giving preferential treatment to particular generations.

description: This publication on Zenodo presents the final analysis of a survey conducted in Task 3.1 and 3.2 of WP3 of HealthyCloud project. The aim of the survey was to carry out a landscape analysis of available health-related data infrastructures in Europe, evaluate their adherence to the FAIR principles, and determine the feasibility to perform individual level data linkages. The survey focused on health data collections that would be useful to answer the research questions of the cancer and atrial fibrillation use cases. The publication provides administrative information about each data infrastructure, information about the data they provide, data quality aspects, coverage, standards used to structure the data, and their compliance with the FAIR principles. The findings suggest a high level of feasibility of linking individual level data as all the data infrastructures store individual-level data, have national-level coverage, and have pseudonymised data. However, lack of interoperability between different Finnish data collections due to the usage of different standards to structure their data or metadata may hamper data linkage at the individual level. The publication also includes a HealthyCloud FAIRness self-assessment tool that allows the publication of the HealthyCloud FAIRness evaluation survey and the production of a report including pie charts demonstrating the percentage scores for each FAIR principle as well as an overall score. The authors plan to create a publicly available online catalogue with the information collected for each of the data infrastructures in order to make these data infrastructures discoverable to external researchers.

description: By means of ab-initio calculations we investigate the optical properties of pure a-SiN$_x$ samples, with $x \in [0.4, 1.8]$, and samples embedding silicon nanoclusters (NCs) of diameter $0.5 \leq d \leq 1.0$ nm. In the pure samples the optical absorption gap and the radiative recombination rate vary according to the concentration of Si-N bonds. In the presence of NCs the radiative rate of the samples is barely affected, indicating that the intense photoluminescence of experimental samples is mostly due to the matrix itself rather than to the NCs. Besides, we evidence an important role of Si-N-Si bonds at the NC/matrix interface in the observed photoluminescence trend.

description: We present Spitzer IRAC (2.1 sq. deg.) and MIPS (6.5 sq. deg.) observations of star formation in the Ophiuchus North molecular clouds. This fragmentary cloud complex lies on the edge of the Sco-Cen OB association, several degrees to the north of the well-known rho Oph star-forming region, at an approximate distance of 130 pc. The Ophiuchus North clouds were mapped as part of the Spitzer Gould Belt project under the working name `Scorpius'. In the regions mapped, selected to encompass all the cloud with visual extinction AV>3, eleven Young Stellar Object (YSO) candidates are identified, eight from IRAC/MIPS colour-based selection and three from 2MASS K/MIPS colours. Adding to one source previously identified in L43 (Chen et al. 2009), this increases the number of YSOcs identified in Oph N to twelve. During the selection process, four colour-based YSO candidates were rejected as probable AGB stars and one as a known galaxy. The sources span the full range of YSOc classifications from Class 0/1 to Class III, and starless cores are also present. Twelve high-extinction (AV>10) cores are identified with a total mass of approx. 100 solar masses. These results confirm that there is little ongoing star formation in this region (instantaneous star formation efficiency <0.34%) and that the bottleneck lies in the formation of dense cores. The influence of the nearby Upper Sco OB association, including the 09V star zeta Oph, is seen in dynamical interactions and raised dust temperatures but has not enhanced levels of star formation in Ophiuchus North.

The report includes a detailed definition for a health data hub in the HealthyCloud project, which plays an essential role in enabling the promised advantages by the FAIR principles. Overall, this report provides valuable insights into the current scenario of data hubs managing health data and their compliance with the FAIR principles, as well as best practices for enabling discoverability and increasing the FAIRness level of data collections.
Development of a CFD-based model for the simulation of immobilized photocatalytic reactors for water treatment
Creators: name: Duran, Jose Esteban Duran
Publisher: name: University of British Columbia
Year: 2010

description: A computational fluid dynamics (CFD) model for the simulation of immobilized photocatalytic reactors for water treatment was developed and evaluated experimentally. The model integrated hydrodynamics, species mass transport, chemical reaction kinetics, and irradiance distribution within the reactor. For the development of this integrated CFD model, each of the above phenomena was individually evaluated against experimental data and proper models were identified. The experimental evaluation was performed using various configurations of annular reactors and UV lamp sizes, over a wide range of hydrodynamic conditions (350<Re<11,000). The comparison of modeling and experimental data indicated that the developed CFD model was able to successfully predict the photocatalytic degradation rate of model pollutants (benzoic acid and 2,4-D) in the analyzed reactors. In terms of hydrodynamic models, the results demonstrated that the laminar model performed well for systems under laminar flow conditions (error < 8%), whereas the Abe-Kondoh-Nagano (AKN) low Reynolds number (error < 12%) and the Reynolds stress (RSM) (error < 19%) turbulence models gave accurate predictions of the coated photoreactor performances under transitional or turbulent flow regimes. The degradation prediction capability of the CFD model was largely determined by the external mass transfer prediction performance of the hydrodynamic models utilized. The developed radiation field model included the lamp within the computational domain allowing to incorporate important interactions between the UV radiation, the quartz walls, and the Hg vapour inside the lamp. A modification of the extensive source volumetric lamp emission model that incorporates the high photon absorbance/re-emission effect produced by the Hg vapour in the lamp (ESVERA model) showed excellent agreement with near- and far-field experimental data. An effective optimization design approach which combines CFD modeling and the Taguchi design of experiments (DOE) method was presented for annular reactors with repeated ribs as external mass transfer promoters. The statistical analysis showed that the reactor performance was improved using small outer tube diameters, large inner/outer tube diameter ratios, intermediate (rib height)/(hydraulic diameter) ratio, and small (rib pitch)/(rib height) ratios. Moreover, the (rib height)/(hydraulic diameter) ratio was the design parameter having the greatest impact (57%) on photoreactor performance.

description: A new method of symbolic analysis based on finite discretization of velocity-curvature space is proposed. A minimum alphabet is introduced in a natural way, and a number of initial analytic measures are defined that make it possible to study the structure of discrete mapping dynamics. The proposed method is tested by application to a system of two unidirectionally coupled logistic maps. It is shown that this method can be used to reveal and study changes in the structure of attractors. In the given example, features in the attractor structure of the driven subsystem are studied upon its escape from the identical synchronization regime.

Rational Secret Sharing over an Asynchronous Broadcast Channel with Information Theoretic Security

description: We consider the problem of rational secret sharing introduced by Halpern and Teague [1], where the players involved in secret sharing play only if it is to their advantage. This can be characterized in the form of preferences. Players would prefer to get the secret than to not get it and secondly with lesser preference, they would like as few other players to get the secret as possible. Several positive results have already been published to efficiently solve the problem of rational secret sharing but only a handful of papers have touched upon the use of an asynchronous broadcast channel. [2] used cryptographic primitives, [3] used an interactive dealer, and [4] used an honest minority of players in order to handle an asynchronous broadcast channel. In our paper, we propose an m-out-of-n rational secret sharing scheme which can function over an asynchronous broadcast channel without the use of cryptographic primitives and with a non-interactive dealer. This is possible because our scheme uses a small number, k+1, of honest players. The protocol is resilient to coalitions of size up to k and furthermore it is ε-resilient to coalitions of size up to and including m-1. The protocol will have a strict Nash equilibrium with probability Pr((k+1)/n) and an ε-Nash equilibrium with probability Pr((n-k-1)/n) . Furthermore, our protocol is immune to backward induction. Later on in the paper, we extend our results to include malicious players as well. We also show that our protocol handles the possibility of a player deviating in order to force another player to get a wrong value in what we believe to be a more time efficient manner than was done in Asharov and Lindell [5].

description: The dynamical properties of longitudinal and transverse conduction of NbSe$_3$ single-crystals have been simultaneously studied when the current is applied along the b axis (chain direction). In the vicinity of the threshold electric field for CDW sliding, the transverse conduction sharply decreases. When a rf field is applied, voltage Shapiro steps for longitudinal transport are observed as usual, but also current Shapiro steps in the transverse direction. The possible mechanisms of this effect are discussed.

description: This dissertation examines how local populations in the Roman East responded to empire-wide trends by focusing on the construction of Roman-style baths. Specifically, it explores the degree to which provincial building industries applied their own well-developed and deeply entrenched building traditions to the construction of these baths. It also pays special attention to the environmental factors that conditioned these local building traditions and limited the choice of construction materials and techniques at the disposal of those tasked with building these facilities. To investigate the reception of Roman-style baths by provincial communities as well as the means by which local building industries overcame the structural and technical challenges posed by these novel structures, this dissertation examines the construction of 90 bathing facilities throughout the Roman East, from Cilicia to Arabia. In doing so, it demonstrates that while Roman-style baths were universally adopted by provincial communities, they were not passively received. Instead, wherever possible, the construction of baths was adapted to fit the environmental contexts and architectural traditions of local building industries. At the same time, this dissertation explores how, when faced with the technical challenges presented by Roman-style baths (such as the vaulting and heating systems), the builders of these facilities imported western techniques or developed innovative solutions derived from their own building practices. The investigation of these instances of importation and innovation elucidates vehicles of technological transmission to (and within) the Roman East as well as the ingenuity of provincial builders. Rather than presenting a comprehensive analysis of all known Roman-style baths from the Roman East, this dissertation draws from a representative sample and focuses on the construction of the walls, vaults, and heating systems of these facilities, where innovation and local influences are most visible. The focus on these three elements allows for architectural analysis at the necessary level of detail, while the transregional scope of this study enables the broader, interregional contextualization of cultural trends previously identified by regional or localized studies.

description: In the present article, we investigate the properties of motion in Hamiltonian systems of two and three degrees of freedom, using the distribution of the values of two new dynamical parameters. The distribution functions of the new parameters, define the S(g) and the S(w) dynamical spectra. The first spectrum definition, that is the S(g) spectrum, will be applied in a Hamiltonian system of two degrees of freedom (2D), while the S(w) dynamical spectrum will be deployed in a Hamiltonian system of three degrees of freedom (3D). Both Hamiltonian systems, describe a very interesting dynamical system which displays a large variety of resonant orbits, different chaotic components and also several sticky regions. We test and prove the efficiency and the reliability of these new dynamical spectra, in detecting tiny ordered domains embedded in the chaotic sea, corresponding to complicated resonant orbits of higher multiplicity. The results of our extensive numerical calculations, suggest that both dynamical spectra are fast and reliable discriminants between different types of orbits in Hamiltonian systems, while requiring very short computation time in order to provide solid and conclusive evidence regarding the nature of an orbit. Furthermore, we establish numerical criteria in order to quantify the results obtained from our new dynamical spectra. A comparison to other previously used dynamical indicators, reveals the leading role of the new spectra.

description: Rural education stands as the bedrock of national education and a linchpin for achieving high-quality, balanced development in line with China's strategic goals. The 19th National Congress of the Communist Party of China underscored the need to accelerate the integration of rural and urban education and optimize resource allocation to realize the nation's second centennial goal. In this context, the vital role of rural teachers in revitalizing rural education cannot be overstated.
Guangdong Province, in a pioneering move, launched a publicly funded targeted training program for primary and secondary school teachers in its eastern, western, and northern regions since 2018, referred to as "targeted normal school students." This innovative initiative aims to cultivate highly qualified educators in subject areas with shortages, specifically catering to rural kindergartens, special education schools, and compulsory education institutions. Notably, it marks Guangdong as the first province in China to provide government-funded training for education master's degree students.
By 2022, the program had successfully enrolled 12,600 participants, receiving annual funding of 20,000 RMB per student for undergraduate programs and 30,000 RMB per student for graduate programs. This initiative stands as a testament to the commitment of both the nation and its people towards bolstering rural education.
In this endeavor, educational institutions, especially universities, assume a pivotal role in nurturing locally-rooted, high-quality rural teachers, thus contributing significantly to the advancement of high-quality and balanced compulsory education.

description: Physics in curved spacetime describes a multitude of phenomena, ranging from astrophysics to high energy physics. The last few years have witnessed further progress on several fronts, including the accurate numerical evolution of the gravitational field equations, which now allows highly nonlinear phenomena to be tamed. Numerical relativity simulations, originally developed to understand strong field astrophysical processes, could prove extremely useful to understand high-energy physics processes like trans-Planckian scattering and gauge-gravity dualities. We present a concise and comprehensive overview of the state-of-the-art and important open problems in the field(s), along with guidelines for the next years. This writeup is a summary of the "NR/HEP Workshop" held in Madeira, Portugal from August 31st to September 3rd 2011.

description: Cette communication se basera sur le travail de doctorant(e)s, jeunes docteur(e)s de disciplines différentes (sociologie, information et communication, esthétique, etc.) mais dont le parcours et les démarches méthodologiques se font écho autour d’objets émergents  : communautés et espaces en ligne/hors ligne d’action et de production collective (hacker/makerspace, hackathon). Les travaux issus de l’Ecole de Chicago et leurs nombreuses filiations (théorisation enracinée, analyse situationnelle, etc.) (Guillemette et Luckerhoff, 2009; Clarke 2005) ont été source d’inspiration pour construire leur approche qualitative.

Ils ont été aussi une aide pour définir leur posture de recherche et accepter de "s'émanciper" (Hughes 1996) et de ne pas mettre de côté le bagage des expériences passées ou en cours pour l’analyse de leur terrain (Emerson, 2003). Au contraire, c’est par une nécessaire immersion où les limites entre chercheurs et "faiseurs"/ “bricoleurs” sont floues que la diversité des pratiques et des formes d’organisation se sont dessinées ou ont été expérimentées.

Plus qu’une approche d’observation participante, les notions de participation observante (Soulé, 2007), d'"expérience-enquête" (Schnapper 2011), d’empathie fertile (Bosqué, 2016) ont été nécessaires pour appréhender ces milieux et mettre en évidence des médiations sociales difficilement accessibles par des approches sociologiques classiques (Hamel, 1997).

description: A 2D tunneling network consisting of nanoclusters placed on a surface is studied. It is shown that such a network is capable of transferring large supercurrent at high temperatures. For a realistic set of parameters the damping is quite small, and the smallness is due to strong renormalization of the capacitance of a cluster. The critical field also turns out to be lar

description: We use the theory of quantum estimation in two different qubit-boson coupling models to demonstrate that the temperature of a quantum harmonic oscillator can be estimated with high precision by quantum-limited measurements on the qubit. The two models that we address embody situations of current physical interest due to their connection with ongoing experimental efforts on the control of mesoscopic dynamics. We show that population measurements performed over the qubit probe are near optimal for a broad range of temperatures of the harmonic oscillator
