Parallelism for Quantum Computation with Qudits

Robust quantum computation with d-level quantum systems (qudits) poses two requirements: fast, parallel quantum gates and high fidelity two-qudit gates. We first describe how to implement parallel single qudit operations. It is by now well known that any single-qudit unitary can be decomposed into a sequence of Givens rotations on two-dimensional subspaces of the qudit state space. Using a coupling graph to represent physically allowed couplings between pairs of qudit states, we then show that the logical depth of the parallel gate sequence is equal to the height of an associated tree. The implementation of a given unitary can then optimize the tradeoff between gate time and resources used. These ideas are illustrated for qudits encoded in the ground hyperfine states of the atomic alkalies $^{87}$Rb and $^{133}$Cs. Second, we provide a protocol for implementing parallelized non-local two-qudit gates using the assistance of entangled qubit pairs. Because the entangled qubits can be prepared non-deterministically, this offers the possibility of high fidelity two-qudit gates.Comment: 9 pages, 3 figure

Analysis of the transaction costs and administration benefits associated with Behind The Label

Compliance with government regulations represents a cost to business operations. Of all compliance activities, compliance with taxation regulations and legislation constitutes a significant proportion of business expense. Estimates obtained in this study by Phillip O\u27Neill and Grahame O\u27Leary suggest that compliance with licensing and other arrangements of the proposed Ethical Clothing Trades Act account for less than five per cent of total compliance costs

In Situ Nanomechanical Measurements of Interfacial Strength in Membrane-Embedded Chemically Functionalized Si Microwires for Flexible Solar Cells

Arrays of vertically aligned Si microwires embedded in polydimethylsiloxane (PDMS) have emerged as a promising candidate for use in solar energy conversion devices. Such structures are lightweight and concurrently demonstrate competitive efficiency and mechanical flexibility. To ensure reliable functioning under bending and flexing, strong interfacial adhesion between the nanowire and the matrix is needed. In situ uniaxial tensile tests of individual, chemically functionalized, Si microwires embedded in a compliant PDMS matrix reveal that chemical functionality on Si microwire surfaces is directly correlated with interfacial adhesion strength. Chemical functionalization can therefore serve as an effective methodology for accessing a wide range of interfacial adhesion between the rigid constituents and the soft polymer matrix; the adhesion can be quantified by measuring the mechanical strength of such systems

Synthesis and Characterization of Mixed Methyl/Allyl Monolayers on Si(111)

The formation of mixed methyl/allyl monolayers has been accomplished through a two-step halogenation/alkylation reaction on Si(111) surfaces. The total coverage of alkylated Si, the surface recombination velocities, and the degree of surface oxidation as a function of time have been investigated using X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, and microwave conductivity measurements. The total coverage of alkyl groups, the rate of oxidation, and the surface recombination velocities of Si(111) terminated by mixed monolayers were found to be close to those observed for CH_3−Si(111) surfaces. Hence, the mixed-monolayer surfaces retained the beneficial properties of CH_3−Si(111) surfaces while allowing for convenient secondary surface functionalization

The Auld Sod: Staging the Diaspora at the 1897 Irish Fair in New York City

The 1897 Irish Fair in New York City is significant for its map exhibit of a topographical map of Ireland, with soil from each county represented. For ten cents, participants could walk across the map and stand again on the soil of Ireland. This article examines the map exhibit as demonstrating diasporic nationalism of the late nineteenth century Irish emigrant, and also reads the exhibit as a contrapuntal political discourse on Irish nationalism, Anglo/American relations, and the position of the Irish immigrant in New York

Bioavailability and Modes of Action of Novel Metal Based Phenanthroline Drugs

Metal-basedcompounds have been utilised as chemotherapeutic agents for the last four decades due to their well-documented and clinically relevant anti-tumour properties.Acquired resistance is a challenge for the clinical use of these compounds and there is a continuing need to search for potential new therapeutic agents. Herein, the potential of two metal-basedcompounds containing chelated1,10-phenanthroline (1,10-Phen), one manganese-based (CMPD 73)andonecopper-based (CMPD 74), to act as novel therapeutic agents is explored.CMPD 73 displayed high micromolar (IC50\u3e100μM) cytotoxic properties againstvarious cell systems but interestingly displayed increased cytotoxicity against ovarian (A2780), lung (A549) and cisplatin resistant mesothelioma cells(IC5040-50μM). CMPD 74 was equally cytotoxic against all cell lines tested(IC5

Kako biti holist koji odbacuje biopsihosocijalni model

After nearly fifty years of mea culpas and explanatory additions, the biopsychosocial model is no closer to a life of its own. Bolton and Gillett give it a strong philosophical boost in The Biopsychosocial Model of Health and Disease, but they overlook the model’s deeply inconsistent position on dualism. Moreover, because metaphysical confusion has clinical ramifications in medicine, their solution sidesteps the model’s most pressing clinical faults. But the news is not all bad. We can maintain the merits of holism as we let go of the inchoate bag of platitudes that is the biopsychosocial model. We can accept holism as the metaphysical open door that it is, just a willingness to recognize the reality of human experience, and the sense in which that reality forces medicine to address biological, psychological, and social aspects of health. This allows us to finally characterize Engel’s driving idea in accurate philosophical terms, as acceptance of (phenomenal) consciousness in the context of medical science. This will not entirely pin down medicine’s stance on dualism, but it will position it clearly enough to readily improve patient care.Nakon gotovo pedeset godina mea culpas i objašnjavajućih dodataka, biopsihosocijalni model nije ništa bliži vlastitom životu. Bolton i Gillett daju mu snažan filozofski poticaj u Biopsihosocijalnom modelu zdravlja i bolesti, ali zanemaruju duboko nedosljedan stav koji model ima prema dualizmu. Štoviše, budući da metafizička zbrka ima kliničke posljedice u medicini, njihovo rješenje zaobilazi najhitnije kliničke greške modela. Ali nije sve tako crno. Možemo zadržati dobre strane holizma istovremeno napuštajući floskule koje pretpsotavlja biopsihosocijalni model. Možemo prihvatiti holizam kao metafizički otvorena vrata koja on jest, samo spremnost da se prepozna stvarnost ljudskog iskustva i smisao u kojem ta stvarnost tjera medicinu da se pozabavi biološkim, psihološkim i društvenim aspektima zdravlja. To nam omogućuje da konačno okarakteriziramo Engelovu pokretačku ideju u točnim filozofskim terminima, kao prihvaćanje (fenomenalne) svijesti u kontekstu medicinske znanosti. To neće u potpunosti odrediti stav medicine prema dualizmu, ali će ga postaviti dovoljno jasno da se lako poboljša skrb za pacijente

THE ENTANGLEMENT OF INFLUENTIAL TECHNOLOGY CHANNELS IN PRACTICE AND DESIGN

Design for academic practice is an important phenomenon in Higher Education. This is the practice through which informal, non-professional designers operating in a variety of roles in academic institutions carry out the design of systems, resources, activities and processes that are intended to enhance academic practice. Despite its importance, the area has not received sufficient attention in studies of academic practice, quality enhancement and digital transformation. This thesis argues that the absence of insight into how designers for academic practice engage with digital technology in their design practice contributes to the mismatch between the ambitions for digital transformation in higher education and the reality of how digital technology is used in higher education. This research has developed an approach to address this issue and enhance how designers for academic practice engage with the digital technologies that are enacted in the practices of lecturers in an academic institution. This approach adopts a novel theoretical lens developed for this research, termed Influential Technology Channels, that produces a model of technology use in everyday practice and provides access, through the existing use of technology, to the enactment of academic practice. This model is used alongside another contribution from this research, practice-based personas – a modelling method that represents the diverse collections of technology use that constitute academic practice, and thus enables designers for academic practice to navigate and engage with the diversity of practice in the population of lecturers in the academic institution. Using this approach to design for academic practice, the form of design characterised and investigated in this research, informal designers are supported to achieve a greater understanding of the audience for which they are designing and explore designs that build upon existing, diverse, situated practice in ways that would not otherwise be possible. Through the implementation of an instrumental case study, this research demonstrates how these methods provide the meaningful connections between design and practice that can support digital enhancement and digital transformation initiatives on a broad scale, enabling designers to better engage with diverse people, practices and uses of digital technology as they seek to enhance academic practice
