Bottom-up Nanoelectronics
Creators: name: Hadley, Peter
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2004
Subjects: ING-INF/01 Elettronica

description: Nanoelectronics is a broad topic that spans
molecular devices to silicon field-effect transistors. While
the development of nanoscale silicon devices is an important
topic, the focus here will be on the challengers to silicon
such as molecules, carbon nanotubes, and nanowires. In
high performance applications like computation or
communications, the challengers might be able to provide
devices that are about as fast, and about as small as those
that will be made in the near future in silicon. It is not in
terms of performance that silicon will be challenged. The
real potential of the challengers is that they may eventually
provide about the same performance as silicon for a lower
price.

description: New semiconductor technologies, used in passive
microwave applications, allow the integration of passives
with high quality factors and the fabrication of novel RFMEMS
components for switches and tunable capacitors and
resonators. The use of these technologies results in a strong
reduction of the size and the power consumption of
wearable microwave systems. The scaling of silicon
transistors, following Moore’s law, results in RF-CMOS
devices approaching the performance of III-V and SiGe
devices but at a considerably lower cost and much higher
integration capability. The introduction of GaN based
technologies offering new possibilities in the field of power
microwave devices is discussed.

description: We report observations of Faraday rotation measures (RMs) for a sample of 191 extragalactic radio jets observed within the MOJAVE program. Multifrequency VLBA observations were carried out over twelve epochs in 2006 at four frequencies between 8 and 15 GHz. We detect parsec-scale Faraday RMs in 149 sources and find the quasars to have larger RMs on average than BL Lac objects. The median core RMs are significantly higher than in the jet components. This is especially true for quasars where we detect a significant negative correlation between the magnitude of the RM and the de-projected distance from the core. We perform detailed simulations of the observational errors of total intensity, polarization and Faraday rotation, and concentrate on the errors of transverse Faraday RM gradients in unresolved jets. Our simulations show that the finite image restoring beam size has a significant effect on the observed RM gradients, and spurious gradients can occur due to noise in the data if the jet is less than two beams wide in polarization. We detect significant transverse RM gradients in four sources (0923+392, 1226+023, 2230+114 and 2251+158). In 1226+023 the RM is for the first time seen to change sign from positive to negative over the transverse cuts, which supports the presence of a helical magnetic field in the jet. In this source we also detect variations in the jet RM over a time scale of three months, which are difficult to explain with external Faraday screens and suggest internal Faraday rotation. By comparing fractional polarization changes in jet components between the four frequency bands to depolarization models we find that an external purely random Faraday screen viewed through only a few lines of sight can explain most of our polarization observations but in some sources, such as 1226+023 and 2251+158, internal Faraday rotation is needed.

description: At the time of the Budapest Manifesto, self-archiving supporters looked like a revolutionary, "anti-commercial publishers" movement. Today, after some years debate (and technological innovation in research and scientific e-publishing), antagonist positions are able to compromise and consider the tradeoffs. What is really changing in the Authors' attitude towards institutional or disciplinary repositories, and peer reviewed open access journals? Many recent papers have investigated these topics. From these sources we can note that Biomedical Authors behave differently from Physicists, Astronomers and Mathematicians, who have been using open archives for such a long time. Therefore we intend to analyze these different trends in the diverse communities. Several aspects also deserve a careful attention: the role of new OA journals in evaluation processes (i.e. their impact and citations), implementation and maintenance costs of institutional repositories, the evolution of bibliometric indicators. We intend also to discuss the role of libraries in service innovation and e-publishing promotion. The main areas where a key role may be played are: institutional repository management and users' training, the promotion of OA journals and information about evaluation methods (both qualitative and quantitative). We think that the transition towards new communication models may be a great opportunity that libraries have to be ready to support.

description: Hubble Space Telescope observations of globular clusters (GCs) in the Antennae galaxy show clusters of clusters, or regions in the galaxy that span hundreds of parsecs, where many of the GCs are doomed to collide, and eventually merge. Several such objects appear likely to present a significant range in ages, hence possibly metallicities, and their merger could plausibly lead to multi-metallic GCs. Here we explore this process with direct-summation N-body simulations with GPU hardware. Our results reveal that colliding GCs with different metallicities and ages can produce a GC with multiplicity and occupation fractions not unlike those observed in multi-metallic clusters. In our simulations, the merged clusters have a phase with a larger amount of flattening than average, as a consequence of rapid rotation- thus suggesting that relatively recent mergers may play a role in producing highly flattened, multi-metallic clusters. We additionally explore the role of the King parameter of the cluster in the occupation fractions with a set of 160 direct-summation simulations and find that for equal size clusters the King parameter of the progenitor clusters determines the occupation fractions in the merger product, while in unequal size mergers the size of the clusters dominates the distribution of stars in the new GC. In particular, we find that the observed distribution of populations in Omega Cen can be described to some extent with our dynamical models.

Representation of Quantum Field Theory by Elementary Quantum Information

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper is considered relativistic quantum field theory expressed by elementary units of quantum information as they are considered as fundamental entity of nature by Carl Friedrich von Weizsaecker. Through quantization of a Weyl spinor describing an elementary unit of quantum information and consisting of four real components one obtains four pairs of creation and annihilation operators acting in a tensor space of states containing many units of quantum information. There can be constructed position and momentum operators from the creation and annihilation operators and based on these operators the Poincare group can be represented in this abstract tensor space of quantum information. A general state in the tensor space can be mapped to a state in Minkowski space-time by using the position representation of the eigenstates of the occupation number operators which correspond to the eigenstates of the harmonic oscillator. This yields a description of relativistic quantum mechanics. Quantization of the coefficients of a general state in the tensor space leads to many particle theory and thus to quantum field theory.

description: The use of microwave monolithic integrated circuits (MMIC) in future space applications is becoming increasingly probable because of their high performance and low mass. Moreover, certain equipments, such as large active antennas, are only conceivable with MMIC solutions. In order to make sure that such products have quality levels compatible with space requirements, it becomes necessary to establish a qualification methodology taking all the specificities of GaAs MMIC's into consideration. An inter-administration working group with members from France Telecom (CNET), the Delegation Generale de l'Armement (CELAR) and the Centre National d'Etudes Spatiales has been set up to lead thinking on this subject and dialogue with national industry (designers and manufacturers). Apart from the technical characteristics proper to MMIC's, it appeared that three important points have to be taken into account: -These technologies are relatively recent, which means that they are evolving fast and there is virtually no feedback on experience. -It is very difficult to "fix" a fabrication procedure during a space programme time sequence. - It is necessary to work with a manufacturer having his process well under control so as to be able to respond to changes in the fabrication procedure. To take all these necessities into account, our methodology is based on human expert appraisal, which provides great flexibility in the way of working and can manage technological changes without calling established knowledge into question. The approach we propose is centred around three steps : audit, evaluation and procurement.

description: Recently spin-orbit (SO) coupled superfluids in free space or harmonic traps have been extensively studied, motivated by the recent experimental realization of SO coupling for Bose-Einstein condensates (BEC). However, the rich physics of SO coupled BEC in optical lattices has been largely unexplored. In this paper, we show that in suitable parameter region the lowest Bloch state forms an isolated flat band in a one dimensional (1D) SO coupled optical lattice, which thus provides an experimentally feasible platform for exploring the recently celebrated topological flat band physics in lattice systems. We show that the flat band is preserved even with the mean field interaction in BEC. We investigate the superfluidity of the BEC in SO coupled lattices through dynamical and Landau stability analysis, and show that the BEC is stable on the whole flat band.

SARS-CoV-2.

description: Introduction. During the year of the pandemic, caused by SARS-CoV-2, much data on the epidemiological features of the pathogen, clinical and paraclinical characteristics of the disease, diagnostic principles and treatment approaches have been published in the scientific literature. But there are still many unsolved prob-lems regarding the epidemiological and clinical features of the course of coronavirus infection in newborns. Aim. Study of the features of the course of coronavirus infection caused by SARS-CoV-2 in newborns who were treated during 2020 on the basis of the RMUI "Chernivtsi Regional Pediatric Clinical Hospital", Cher-nivtsi. Methods and materials. To achieve this aim, 12 medical records of inpatient infants were retrospectively analyzed. The entry criteria were: age 0-28 days of life, confirmed coronavirus infection, which was detected by a positive nasopharyngeal swab result by polymerase chain reaction (PCR). The average age at the time of admission was 13.6±2.1 days, among which a third (33.3%) of newborns were admitted before the age of 10 days of life. The share of rural residents was 66.6%. Among the infants who became sick, girls prevailed (75%). Conclusions. It was found that contact of the newborns with COVID-19 patients was confirmed in most cases. Most infants were admitted from home on average on the second day after the onset of the disease, with clinical symptoms typical of acute respiratory viral infections, and only two patients showed signs of gastroin-testinal disorders at the onset of the disease. The course of the disease was favourable. The detected changes in the hemogram in the infants in catamnesis require further dynamic clinical and paraclinical monitoring.

description: The widespread use of GaAs MMICs in microwave systems require assembly technologies with high yields and high reliability, while preserving the intrinsic performance of the die. This is a difficult task, given the large lateral dimensions and reduced thickness of MMICs, complicated by the presence of via-holes. This paper will present some of the results obtained during assessment of various techniques used for die-attach. These results show that the major reliability concern is the behaviour of the die attach medium within the via-holes. We will present a new process designed to control this behaviour.
An approximate spatio-temporal Bayesian model for Alberta wheat yield
Creators: name: Popoff, Evan
Publisher: name: University of British Columbia
Year: 2014

description: Crop forecasting models are very valuable to a number of agricultural and government agencies. We investigated the effect of spatial and temporal environmental climate covariates on the growth of crop yield (wheat) at the regional scale across the province of Alberta. Model fitting was accomplished using data collected during the growing season from climate stations across Alberta provided by Agriculture and Agri-Food Canada (AAFC). A best fitting model was selected which takes into account simplicity (number of covariates used) and accuracy (predictive capability based on two selection criteria). There have been a number of Bayesian methods for predicting wheat yield. However, many of these methods typically involve extensive algorithms such as a Metropolis-Hastings Markov Chain Monte Carlo (MCMC) that adds substantial computational complexity and run-time. We investigated the application of a spatio-temporal Bayesian model entitled the Integrated Nested Laplace Approximation (INLA). This method offers a computationally cheaper alternative to the MCMC approach and is capable of handling large data requiring interpolation (data sparsity) with relative ease. By structuring the model to have a sparse precision matrix, INLA is able to simplify posterior marginal estimation of the parameters by incorporating the Laplace approximation. The INLA model demonstrated strong predictive capabilities when predicting for one year in advance or hind-casting for a it single previous year. However, when multiple years of data were removed or predictions were made for multiple years in advance, INLA struggled to make predictions which deviated considerably from the mean of the remaining data. Predictive performance in the best fitting model saw a 40% increase in root mean squared error (RMSE) when moving from one year to two and another 6% increase when moving from two to three years. We conclude that the INLA model structure offers valuable information when examining one year in advance but caution should be taken when attempting to forecast for multiple years in advance.

description: After gaining political independence on October 18, 1991, one of the priorities and main tasks for the economic growth of Azerbaijan was the establishment of foreign economic relations in the proper directions. The implementation of economic reforms has intensified in the country. The establishment of industrial and social infrastructure has begun, transport communications have been formed, new technologies have been ob-tained, the training of qualified personnel for the branches of the national economy has been implemented, and the list of countries exporting Azerbaijani products has expanded. In this regard, the article examines the role of Azerbaijan's foreign economic activity as one of the crucial factors affecting the sustainable develop-ment of the national economy. The foreign trade turnover of the Republic of Azerbaijan, its main trading part-ners, the structure of goods and services of export and import have been revealed. Also, the article identifies current trends in Azerbaijan's foreign trade and priority areas of development of the economy of Azerbaijan

description: We consider the problem of providing optimal uncertainty quantification (UQ) --- and hence rigorous certification --- for partially-observed functions. We present a UQ framework within which the observations may be small or large in number, and need not carry information about the probability distribution of the system in operation. The UQ objectives are posed as optimization problems, the solutions of which are optimal bounds on the quantities of interest; we consider two typical settings, namely parameter sensitivities (McDiarmid diameters) and output deviation (or failure) probabilities. The solutions of these optimization problems depend non-trivially (even non-monotonically and discontinuously) upon the specified legacy data. Furthermore, the extreme values are often determined by only a few members of the data set; in our principal physically-motivated example, the bounds are determined by just 2 out of 32 data points, and the remainder carry no information and could be neglected without changing the final answer. We propose an analogue of the simplex algorithm from linear programming that uses these observations to offer efficient and rigorous UQ for high-dimensional systems with high-cardinality legacy data. These findings suggest natural methods for selecting optimal (maximally informative) next experiments.

A single CHIP transmitter for a spread spectrum direct sequence in-house communication system at 2.4GHz

description: The design of a single chip transmitter for a spread spectrum inhouse communication system working at 2.4GHz is presented. The circuit consists of a frequency doubler (1.2 to 2.4GHz), a double balanced modulator with an LO buffer amplifier, and a seven stage power amplifier for 100mW of output power. Except for the power amplifier output matching network, and a bandpass filter, no additional external components are required. Chip fabrication was performed with a commercial lmm-GaAs-MESFET enhancement/depletion foundry process. Through consequent use of an insensitive circuit design strategy, a high production yield is achieved. From 26 devices investigated, all but one were functional, providing high fundamental suppression without additional filtering. However, a certain output power and temperature sensitivity, together with a high chip-to-chip spread of the carrier suppression, has been observed. At moderate output power levels, about 90% of the devices provided sufficient carrier suppression at less than 1W of power consumption.

SO(2,4)-covariant quantization of the Maxwell field in a conformally flat space
Creators: name: Faci, Sofiane
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We present an SO(2,4)-covariant quantization of the free electromagnetic field in conformally flat spaces (CFS). A CFS is realized in a six-dimensional space as an intersection of the null cone with a given surface. The smooth move of the latter is equivalent to perform a Weyl rescaling. This allows to transport the SO(2,4)-invariant quantum structure of the Maxwell field from Minkowski space to any CFS. Calculations are simplified and the CFS Wightman two-point functions are given in terms of their Minkowskian counterparts. The difficulty due to gauge freedom is surpassed by introducing two auxiliary fields and using the Gupta-Bleuler quantization scheme. The quantum structure is given by a vacuum state and creators/annihilators acting on some Hilbert space. In practice, only the Hilbert space changes under Weyl rescalings. Also the quantum SO(2,4)-invariant free Maxwell field does not distinguish between two CFSs.

Static spherically symmetric black holes with scalar field

description: Static spherically symmetric black holes and particle like solutions with self interacting minimally coupled scalar field ϕ are analyzed. They are asymptotically flat or anti-de Sitter (AdS). We express them in terms of a single function ρ which undergoes simple conditions. If ϕ is nontrivial the ADM mass M has to be positive. No-hair theorems are generalized to the AdS asymptotic. For both asymptotics the Killing horizon is nondegenerate and its radius cannot be bigger than 2M. Derivatives of ρ at singularity determine properties of admissible potentials V(ϕ) as regularity, boundedness and behaviour for maximal values of ϕ. Several classes of solutions with singular or nonsingular potentials are obtained. Their examples are presented in a form of plots.

description: During neural tube closure (NTC), a sheet-like structure of cells folds into a tube that forms the brain and spinal cord. Neural tube defects can arise when cells fail to constrict their apical surfaces, a process dependent on Shroom3. Yet, we lack understanding how Shroom3-constriction is achieved. Mechanisms of cell constriction in the developing embryo vary by organism and stage of development. Each observed constriction mechanism has been associated with a different model, the best-established being “ratchet-like” medioapical constriction, purse-string junctional constriction, and pulsed medioapical constriction. While these models help us distinguish mechanisms by attributes we can visually observe, we need methods to describe more complex mechanisms, with precision. Here, we present a framework to characterize cell constrictions quantitatively, according to cell parameters that are readily measurable and associated with morphogenesis, including protein localization, cell polarity, cell shape descriptors, and cell rearrangement. We use partial least squares regression (PLS) to understand which parameters are associated with cellular apical area changes and apply our framework to in-vivo time-lapse imaging of Xenopus tropicalis during NTC. Using PLS, we generate a model of cell constrictions in wild-type and Shroom3 mutant cells during NTC. Our comparisons highlight possible modes of apical constriction across developmental contexts.

description: We consider a model of asexually reproducing individuals. The birth and death rates of the individuals are affected by a fitness parameter. The rate of mutations that cause the fitnesses to change is proportional to the population size, N. The mutations may be either beneficial or deleterious. In a paper by Yu, Etheridge and Cuthbertson [Ann. Appl. Probab. 20 (2010) 978-1004] it was shown that the average rate at which the mean fitness increases in this model is bounded below by $\log^{1-δ}N$ for any $δ>0$. We achieve an upper bound on the average rate at which the mean fitness increases of $O(\log N/(\log\log N)^2)$.

description: The mathematical structure of higher-dimensional physical phase spaces of the nondiagonal Bianchi IX model is analyzed in the neighborhood of the cosmological singularity by using dynamical system methods. Critical points of the Hamiltonian equations appear at infinities and are of a nonhyperbolic type, which is a generic feature of the considered singular dynamics. The reduction of the kinematical symplectic 2-form to the constraint surface enables the determination of the physical Hamiltonian. This procedure lowers the dimensionality of the dynamics arena. The presented analysis of the phase space is based on canonical transformations. We test our method for the specific subspace of the physical phase space. The obtained results encourage further examination of the dynamics within our approach.

description: In this paper we will discuss for the first time the use of the new "gas foil rotation" technology for growth in a low pressure reactor. InP, GalnAs and GalnAsP layers grown on 2" substrates applying this substrate rotation show film thickness variations less than 2% over the entire wafer. Also resistivity measure­ments on doped binary layers showed variations below 2%. The lattice mismatch variation of ternary and quaternary layers was smaller than 5x10-4. The electrical properties of GalnAs and InP as residual carrier concentration and electron mobility in undoped layers were identical to those measured on reference layers grown in the same reactor on a static susceptor. Growth parameters had not to be modified when using this technique.

description: (Abridged) We study relationships between the SFR and the nuclear properties of X-ray selected AGNs out to z=2.5, using far-IR data in three extragalactic deep fields as part of the PACS Evolutionary Probe (PEP) program. Guided by studies of intrinsic infra-red AGN SEDs, we show that the majority of the FIR emission in AGNs is produced by cold dust heated by star-formation. We uncover characteristic redshift-dependent trends between the mean FIR luminosity (L_fir) and accretion luminosity (L_agn) of AGNs. At low AGN luminosities, accretion and SFR are uncorrelated at all redshifts, consistent with a scenario where most low-luminosity AGNs are primarily fueled by secular processes in their host galaxies. At high AGN luminosities, a significant correlation is observed between L_fir and L_agn, but only among AGNs at low and moderate redshifts (z<1). We interpret this as a signature of the increasing importance of major-mergers in driving both the growth of super-massive black holes (SMBHs) and global star-formation in their hosts at high AGN luminosities. However, we also find that the enhancement of SFR in luminous AGNs weakens or disappears at high redshifts (z>1). This suggests that the role of mergers in SMBH-galaxy co-evolution is less important at these epochs. At all redshifts, we find essentially no relationship between L_fir and nuclear obscuration across five orders of magnitude in obscuring column density, suggesting that various different mechanisms are likely to be responsible for obscuring X-rays in active galaxies. We explain our results within a scenario in which two different modes of SMBH fueling operate among low- and high-luminosity AGNs. We postulate, guided by emerging knowledge about the properties of high redshift galaxies, that the dominant mode of accretion among high-luminosity AGNs evolves with redshift.

description: This paper presents a novel method to investigate the efficiency of a tripler with a HBV diode based on Al0.7Ga0.3As/GaAs. The HBV diodes with different mesa diameters have been fabricated and their DC characteristics have been measured. These characteristics are used by a combined genetic algorithm/harmonic balance simulator to calculate the optimum impedances and output powers at the frequency of 255 GHz. A comparison of the conversion efficiencies are presented for the different structures.
Impacts of internal communication on dynamic schedules in mega highway projects
Creators: name: Shamloo, Mohammad Amin
Publisher: name: University of British Columbia

description: Traditionally, construction project management has consisted of three main areas of focus: 1- cost, 2- schedule, and 3- quality. This style of project management primarily developed for new projects has changed during the development and maintenance of transportation infrastructure projects in past years. During this time, these management practices were used for projects that would replace, repair, or expand existent transportation infrastructure. This change in direction has ultimately remodeled current management practices, that focused on the mitigation of risks associated with quality, time and costs. Thus, it is crucial for today’s project management teams to understand and effectively convey the relationships between communication, resources, and organizational hierarchy with scheduling conflicts. The main focus of this study was to observe the relationships between communication, resources, and organizational hierarchy, and how they affect construction schedules. This study is presented as a case study on the Port Mann Highway 1 extension project (PMH1) in British Columbia, Canada. At the time of commission, the PMH1 project was the largest infrastructure project in North America, and was based on a design-build contract. The estimated cost for this project was initially set at 2.46 billion dollars, but with the changes initiated to date, the cost may total more than 3 billion dollars by the time of completion. The two main variables that can affect the construction schedule have been identified as communication and resources. The managers of the general contractors through extensive interview processes have indicated that 77% and 62% of the factors that cause delay to the construction schedule are respectively communication and inexperienced labor force. It was also found that, by moving and replacing medium level managers in the organizational hierarchy, the delays to the construction schedule can be minimized. Based on these findings, a recommended solution has been proposed and validated by a second set of interviews with a second group of senior project managers. It is recommended that a strategized use of computer software be utilized in similar infrastructure projects, which will help management staff minimize costly delays and conflicts caused by miscommunication.
