On local-hidden-variable no-go theorems

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

description: The strongest attack against quantum mechanics came in 1935 in the form of a paper by Einstein, Podolsky and Rosen. It was argued that the theory of quantum mechanics could not be called a complete theory of Nature, for every element of reality is not represented in the formalism as such. The authors then put forth a proposition: we must search for a theory where, upon knowing everything about the system, including possible hidden variables, one could make precise predictions concerning elements of reality. This project was ultimatly doomed in 1964 with the work of Bell Bell, who showed that the most general local hidden variable theory could not reproduce correlations that arise in quantum mechanics. There exist mainly three forms of no-go theorems for local hidden variable theories. Although almost every physicist knows the consequences of these no-go theorems, not every physicist is aware of the distinctions between the three or even their exact definitions. Thus we will discuss here the three principal forms of no-go theorems for local hidden variable theories of Nature. We will define Bell inequalities, Bell inequalities without inequalities and pseudo-telepathy. A discussion of the similarities and differences will follow.

description: Misner space, also known as the Lorentzian orbifold $R^{1,1}/boost$, is one of the simplest examples of a cosmological singularity in string theory. In this lecture, we review the semi-classical propagation of closed strings in this background, with a particular emphasis on the twisted sectors of the orbifold. Tree-level scattering amplitudes and the one-loop vacuum amplitude are also discussed.

description: The inner regions of protoplanetary discs (from $\sim$ 0.1 to 10 au) are the expected birthplace of planets, especially telluric. In those high temperature regions, solids can experience cyclical annealing, vaporisation and recondensation. Hot and warm dusty grains emits mostly in the infrared domain, notably in N-band (8 to 13~$μ$m). Studying their fine chemistry through mid-infrared spectro-interferometry with the new VLTI instrument MATISSE, which can spatially resolve these regions, requires detailed dust chemistry models. Using radiative transfer, we derived infrared spectra of a fiducial static protoplanetary disc model with different inner disc ($< 1$ au) dust compositions. The latter were derived from condensation sequences computed at LTE for three initial $C/O$ ratios: subsolar ($C/O=0.4$), solar ($C/O=0.54$), and supersolar ($C/O=1$). The three scenarios return very different N-band spectra, especially when considering the presence of sub-micron-sized dust grains. MATISSE should be able to detect these differences and trace the associated sub-au-scale radial changes. We propose a first interpretation of N-band `inner-disc' spectra obtained with the former VLTI instrument MIDI on three Herbig stars (HD142527, HD144432, HD163296) and one T Tauri star (AS209). Notably, we could associate a supersolar (`carbon-rich') composition for HD142527 and a subsolar (`oxygen-rich') one for HD1444432. We show that the inner disc mineralogy can be very specific and not related to the dust composition derived from spatially unresolved mid-infrared spectroscopy. We highlight the need for including more complex chemistry when interpreting solid-state spectroscopic observations of the inner regions of discs, and for considering dynamical aspects for future studies.

description: Agricultural industries in small geographical areas with limited acreage tend to be overlooked by those not associated with the growing region or industry. Sugarbeets continue to be produced in a relatively small geographic area and with relatively limited acreage in North Dakota and Minnesota. These factors, along with continued debate over policies affecting domestic sugar industries and recent industry expansions, help justify a continued assessment of the economic importance of the sugarbeet industry to the regional economy. Revenues from sugarbeet production and expenditures by processors to North Dakota and Minnesota entities in fiscal 1997 represented the direct economic impacts from the industry. Expenditure information was provided by sugarbeet processing and marketing cooperatives. Secondary economic impacts were estimated using input-output analysis. The sugarbeet industry planted 654,400 acres and harvested 11.9 million tons in 1996. Production and processing activities generated $831.1 million in direct economic impacts. Total (direct and secondary) annual economic impacts from the sugarbeet industry were estimated at $2.3 billion. Direct and secondary employment in the industry was 2,486 and 30,436 full-time equivalent jobs, respectively. Tax revenues generated by the industry in North Dakota and Minnesota were $51 million. In real terms, gross business volume of the sugarbeet industry in the two states has increased 74 percent since 1987. Increases in business activity from the industry have resulted from expanded acreage and increased processing activities. The sugarbeet industry remains an important agricultural industry in North Dakota and Minnesota. Keywords: sugarbeet industry, North Dakota, Minnesota, economic impact

description: The quark-hadron duality in CC and NC neutrino interactions is discussed under assumptions that single pion production is described accurately by the Rein-Sehgal model and that it allows reconstruction of the inclusive cross section in the resonance region. The duality is measured by means of integrals of structure functions in the Nachtmann variable for $Q^2<3$ GeV$^2$. The results depend on the precision with which contributions from single pion production channels in the overall cross sections are known. Several approaches to evaluate them are compared. The duality is predicted to be seen for proton target reactions and to be absent for neutron and isoscalar targets. Two-component duality between resonant and valence quark contributions to structure functions is also investigated.

description: North Dakota has experienced substantial growth in employment during the 1990s, with much of that growth occurring in the manufacturing and exported services sectors. (Exported services include such activities as telemarketing and data processing where the major market for the service is outside North Dakota.) This study presents the employment and demographic characteristics of employees at new and expanding manufacturing and exported services firms in North Dakota. The workers were asked to rate their opportunity for advancement, their opportunity for technical/skills training, and the type of training that would best enable their advancement with their current employer. The workers also described their current housing and their plans to look for different housing. Data came from a survey of workers at 12 new or expanding manufacturing and exported services firms, located in both rural and urban areas across North Dakota. Completed surveys were received from 324 workers, or about 27 percent of the total employees of the 12 firms. About 83 percent of the respondents reported that they were paid an hourly wage, while 17 percent received an annual salary. The overall average hourly wage was $9.92, with manufacturing workers earning an average of $8.70 and exported services workers earning an average of $10.26. Persons between 20 and 40 years old made up more than two-thirds of the workers responding to the survey. Male workers made up 56 percent of the respondents employed by manufacturers but only 41 percent for exported services firms. About 21 percent of the workers, overall, had moved to their present community when they took their current job, while the remaining 79 percent had been residing in the community prior to taking their current job. Almost 62 percent of the respondents owned their current home while 36 percent rented. The respondents most commonly lived in single-family houses (63%), followed by apartments or duplexes (28%), and mobile homes (8%). More than 80 percent of the respondents rated their opportunities for technical/skills training at their current place of employment as good to excellent. Training in computers and computer software was the type of training most often indicated by respondents as being helpful to their advancement at their present place of work. Almost two-thirds of respondents said they would be definitely interested in obtaining training while another 28 percent would be somewhat interested. Less than one person in ten said they were not at all interested in further training.

description: This study aimed to identify the top performing and the bottom performing family farm businesses based upon business performance, and then compare and contrast the perceptions and attitudes towards acquiring management skills and attributes that lead to improved business performance. Using extensive interviews data were obtained from 200 family farm businesses from New South Wales and Victoria covering a range of enterprises. The key findings were, firstly, that for all farmers the maintaining of a stable family relationship was of paramount importance in the running of the farm business. Secondly, that the Top 20% of farmers had high levels of self-efficacy and thus possessed the capability and the competence to perform tasks successfully. High performers also were more committed to the creation of long-term wealth and viewed business skills as a higher priority for training. Low performers were more highly committed to the farm's environmental health, placed a greater emphasis on production and sustainability for training and were more likely to give a lower priority to business issues. Both groups agreed that formal training that involved practical farmers with education skills providing them with tailor-made modules were best suited to their personal learning needs. The consistently high priority of family and business issues suggests that the opportunity exists to integrate the training of attitudes and skills with family, sustainable business practices and community issues. The study was funded by the Rural Industries Research and Development Corporation.

description: The Woodrising farming business has developed from a grazing operation based on a relatively small soldier settlement block in Northern Tasmania. The expansion and diversification has entailed: Purchase of additional land. Leasing land for cropping, for short (seasonal) and long (3-5 year) terms. Managing a nearby farm on behalf of a Board of Trustees. Developing and running smaller, opportunistic agricultural businesses. This paper describes a business review based on the Now, Where, How model: Where is the business now? Description of the current status of the business (enterprises, geographically and financially). Where do the owners want the business to be? Business targets. How? How to get there, and the associated constraints and risks. Diversification based on the identification and use of resources and development of market opportunities has seen the business expand very significantly in the last 15 years. This development has taken place with limited capital, and as a result has been very exposed to the risks of interest rates, markets and weather fluctuations. This business analysis reviews these issues and describes future directions.

description: The interplay between electron-electron interaction and electron-phonon coupling has been one of the key issues in graphene as it can provide information on the origin of enhanced electron-phonon coupling in graphene by foreign atoms. In ytterbium-decorated graphene on SiC substrate, electron-phonon coupling exhibits strong enhancement compared to that of as-grown graphene. Based on angle-resolved photoemission study, the presence of ytterbium is also found to result in the decrease of Fermi velocity, revealing the enhancement of electron-electron interaction within the Fermi liquid theory. Our finding on the concomitant enhancement of electron-electron interaction and electron-phonon coupling suggests a possibility of the interplay between the two representative many-body interactions in graphene decorated with foreign atoms.

Liberalism and the limits of multicultural justice : Isaiah Berlin and the foundations of cultural pluralism
Creators: name: Ackah, Audrey
Publisher: name: University of British Columbia
Year: 2009

description: This paper evaluates liberal theories of multiculturalism from a pluralist approach in order to illustrate the manner in which liberal multiculturalism limits justice in plural societies. I utilize Isaiah Berlin's pluralism and Iris Marion Young's politics of difference as a pluralist perspective through which to assess multicultural justice in Will Kymlicka's theory of multicultural citizenship. I argue that the distributive paradigm and the priority accorded to liberalism in Kymlicka's theory of multiculturalism impede justice in diverse communities. Chapter one outlines the pluralist approach that is used in this thesis. Isaiah Berlin's pluralism, the primary component of the approach, acknowledges the conflicts within plural societies while identifying the dangers associated with monism. Iris Marion Young's politics of difference provides a practical pluralist methodology that supplements Berlin's pluralism. Chapter two describes Will Kymlicka's theory of liberal multiculturalism. Kymlicka argues that multiculturalism furthers the liberal objectives of liberty and equality of opportunity. Chapter three examines the limits that Kymlicka's distributive approach to justice imposes upon multicultural justice. I argue that prioritizing the distributive paradigm above alternative approaches ignores injustices that this paradigm is not equipped to address. In addition, I argue that the manner in which Kymlicka distributes rights among ethnocultural minorities is based upon inadequate foundations and diminishes justice. Chapter four addresses the limits to multicultural justice that result from the privileged position of liberalism in liberal theories of multiculturalism. Universal human rights, the relationship between liberalism and pluralism and the use of liberalism as a standard of justice undermine multicultural justice in Kymlicka's theory. In conclusion, liberalism provides a substantial barrier to the realization of justice in multicultural societies. These limits must be acknowledged and addressed in a theory that attempts to reconcile liberalism with multiculturalism. Isaiah Berlin's model of pluralism provides a superior model of diversity than the prevailing liberal multicultural model advanced by Will Kymlicka.

description: The “long” 18th century, which historiography also calls the “great century” or the “century of happiness”, was neither “great” nor “happy” for a large part of the inhabitants of Transylvania. This thesis of an early modern historian is to be examined and substantiated. Using the example of some petitions from greek catholic clergy, the article examines strategies, processes and mechanisms of emotionalization. The focus is on the content of petitions from bishop Inochentie Micu-Klein and other clerics of the new church to the Viennese court. Not only the concerns of the representatives of the underprivileged population but also the reactions to them are connected with emotions. The petitions use harsh expressions and speak of oppression, tyranny, despotic yoke, hatred, blood, melancholy, supplication and tears. In contrast, the mentions of luck are comparatively thin. Not only in the choice of words, but also in the arguments cited, emotions come to light when attempts are made by all historical means to justify why the non-privileged have rights. This becomes clear when mentioning the glorious past, which goes back a long way, the emphasis on the right of first ownership and the number of inhabitants. In the choice of words and arguments, a typed and routine, recurring pattern becomes clear. Both the arguments of the supplicants and the reactions of the estates also stand for different emotional communities: on the one hand the community of the unprivileged and on the other hand the community of the estates. The question of the extent to which emotions go beyond social and political demarcation and form community should continue to be considered. At the same time, using the example of the content of the petitions and the negative reactions, practices as forms of negotiation become clear, which were expressed in disputes over rank and precedent in the class society of the 18th century in Transylvania. The real social inequalities exacerbated the internal tensions and contradictions in the principality and culminated, for example, in the peasant uprising of 1784. The pleading requests in all appeals from bishop Klein and his successors were unsuccessful. The 18th century turned out to be less “happy” for Transylvania than a century of crises. Even the practices of petitions did not achieve a breakthrough, despite the emotional impact. Nevertheless, the reforms of emperor Joseph II, among others, point to the fact that society was in a process of change, a change that would continue well into the 19th century.

description: One of the long sought-after goals in manipulation of light through light-matter interactions is the realization of magnetic-field-tuneable colouration, so-called magneto-chromatic effect, which holds great promise for optical, biochemical and medical applications due to its contactless and non-invasive nature. This goal can be achieved by magnetic-field controlled birefringence, where colours are produced by the interference between phase-retarded components of transmitted polarised light. Thus far birefringence-tuneable coloration has been demonstrated using electric field, material chirality and mechanical strain but magnetic field control remained elusive due to either weak magneto-optical response of transparent media or low transmittance to visible light of magnetically responsive media, such as ferrofluids. Here we demonstrate magnetically tuneable colouration of aqueous suspensions of two-dimensional cobalt-doped titanium oxide which exhibit an anomalously large magneto-birefringence effect. The colour of the suspensions can be tuned over more than two wavelength cycles in the visible range by moderate magnetic fields below 0.8 T. We show that such giant magneto-chromatic response is due to particularly large phase retardation (>3 pi) of the polarised light, which in its turn is a combined result of a large Cotton-Mouton coefficient (three orders of magnitude larger than for known liquid crystals), relatively high saturation birefringence (delta n = 2 x 10^-4) and high transparency of our suspensions to visible light. The work opens a new avenue to achieve tuneable colouration through engineered magnetic birefringence and can readily be extended to other magnetic 2D nanocrystals. The demonstrated effect can be used in a variety of magneto-optical applications, including magnetic field sensors, wavelength-tuneable optical filters and see-through printing.

Effect of grain size distribution and size-dependent grain heating on molecular abundances in starless and pre-stellar cores

description: We present a new gas-grain chemical model to constrain the effect of grain size distribution on molecular abundances in starless and pre-stellar cores. We introduce grain-size dependence simultaneously for cosmic-ray (CR)-induced desorption efficiency and for grain equilibrium temperatures. We keep explicit track of ice abundances on a set of grain populations. We find that the size-dependent CR desorption efficiency affects ice abundances in a highly non-trivial way that depends on the molecule. Species that originate in the gas phase follow a simple pattern where the ice abundance is highest on the smallest grains (the most abundant in the distribution). Some molecules, such as HCN, are instead concentrated on large grains throughout the time evolution, while others (like $\rm N_2$) are initially concentrated on large grains, but at late times on small grains, due to grain-size-dependent competition between desorption and hydrogenation. Most of the water ice is on small grains at high medium density ($n({\rm H_2}) \gtrsim 10^6 \, \rm cm^{-3}$), where the water ice fraction, with respect to total water ice reservoir, can be as low as $\sim 10^{-3}$ on large (> 0.1 $μ$m) grains. Allowing the grain equilibrium temperature to vary with grain size induces strong variations in relative ice abundances in low-density conditions where the interstellar radiation field and in particular its ultraviolet component are not attenuated. Our study implies consequences not only for the initial formation of ices preceding the starless core stage, but also for the relative ice abundances on the grain populations going into the protostellar stage. In particular, if the smallest grains can lose their mantles due to grain-grain collisions as the core is collapsing, the ice composition in the beginning of the protostellar stage could be very different to that in the pre-collapse phase.

description: In the drying process of paste, we can imprint into the paste the order how it should be broken in the future. That is, if we vibrate the paste before it is dried, it remembers the direction of the initial external vibration, and the morphology of resultant crack patterns is determined solely by the memory of the direction. The morphological phase diagram of crack patterns and the rheological measurement of the paste show that this memory effect is induced by the plasticity of paste.

description: We present a unified framework for renormalization group methods, including Wilson's numerical renormalization group (NRG) and White's density-matrix renormalization group (DMRG), within the language of matrix product states. This allows improvements over Wilson's NRG for quantum impurity models, as we illustrate for the one-channel Kondo model. Moreover, we use a variational method for evaluating Green's functions. The proposed method is more flexible in its description of spectral properties at finite frequencies, opening the way to time-dependent, out-of-equilibrium impurity problems. It also substantially improves computational efficiency for one-channel impurity problems, suggesting potentially \emph{linear} scaling of complexity for $n$-channel problems.

description: Theory and observations suggest that single-star evolution is not able to produce black holes (BHs) with masses in the range $3-5M_{\odot}$ and above $\sim 45M_{\odot}$, referred to as the lower mass gap (LMG) and the upper mas gap (UMG), respectively. However, it is possible to form BHs in these gaps through merger of compact objects in dense clusters, e.g. the LMG and the UMG can be populated through binary neutron star- and BBH mergers, respectively. This implies that if binary mergers are observed in gravitational waves (GWs) with at least one mass gap object, then either clusters are effective in assembling binary mergers, or our single-star models have to be revised. Understanding how effective clusters are at populating both mass gaps have therefore major implications for both stellar- and GW astrophysics. In this paper we present a systematic study on how efficient stellar clusters are at populating both mass gaps through in-cluster GW mergers. For this, we derive a set of closed form relations for describing the evolution of compact object binaries undergoing dynamical interactions and GW merger inside their cluster. By considering both static and time evolving populations, we find in particular that globular clusters are clearly inefficient at populating the LMG in contrast to the UMG. We further describe how these results relate to the characteristic mass, time, and length scales associated with the problem.

description: Ga(In, Al)N alloys are used as an active layer or cladding layer in light emitting diodes and laser diodes. x-ray diffraction is extensively used to evaluate the crystalline quality, the chemical composition and the residual strain in Ga(Al,In)N thin films, which directly determine the emission wavelength and the device performance. Due to the minor mismatch in lattice parameters between Ga(Al, In)N alloy and a GaN virtual substrate, x-ray diffraction comes to a problem to separate the signal from Ga(Al,In)N alloy and GaN. We give a detailed comparison on different diffraction planes. In order to balance the intensity and peak separation between Ga(Al,In)N alloy and GaN, (0004) and (1015) planes make the best choice for symmetric scan and asymmetric scan, respectively.

description: This paper analyses the potential and limitations of airborne remote sensing systems for detecting crop growth variability and weed infestation within paddocks at specified capture times. The detection of areas of crop growth variability can help farmers become aware of regions within their paddock where they may be experiencing above and below average yields due to changes in soil or management conditions. For instance, the early detection of weed infestation within cereal crops is crucial for lessening their impact on the final yield. Transect sampling within a canola paddock of a broad acre agricultural property in the South West of Western Australia was conducted synchronous with the capture of 1m spatial resolution DMSI. The four individual bands (blue, green, red and near- infrared) of the DMSI were correlated with LAI and weed density counts collected in the paddock. Statistical analyses show the LAI of canola had strong negative correlations with the blue (-0.93) and red (-0.89) bands and a strong positive correlation was found with the near-infrared band (0.82). The strong correlations between the canola LAI and selected bands of the DMSI indicate that this may be a suitable technique for monitoring canola variability to derive information layers that can be used in creating meaningful "within-field" management units. Likewise, DMSI could be used as a non-invasive tool for in season crop monitoring. The correlation analysis with the weed density (e.g. self sown wheat, ryegrass and clover) attributed to only one negative weak correlation with the red band (-0.38). The less successful detection of weeds is attributed to the minimal weeddensity within the paddock (e.g. mean 34 plants m-2) and indistinct spectral difference from canola at the early time of imagery capture required by farmers for effective variable rate applications of herbicides.

description: The state of a single-species monatomic gas from near-equilibrium to highly nonequilibrium conditions is investigated using analytical and numerical methods. Normal solutions of the Boltzmann equation for Fourier flow (uniform heat flux) and Couette flow (uniform shear stress) are found in terms of the heat-flux and shear-stress Knudsen numbers. Analytical solutions are found for inverse-power-law molecules from hard-sphere through Maxwell at small Knudsen numbers using Chapman-Enskog (CE) theory and for Maxwell molecules at finite Knudsen numbers using a moment-hierarchy (MH) method. Corresponding numerical solutions are obtained using the Direct Simulation Monte Carlo (DSMC) method of Bird. The thermal conductivity, the viscosity, and the Sonine-polynomial coefficients of the velocity distribution function from DSMC agree with CE results at small Knudsen numbers and with MH results at finite Knudsen numbers. Subtle differences between inverse-power-law, variable-soft-sphere, and variable-hard-sphere representations of Maxwell molecules are observed. The MH and DSMC results both indicate that the effective thermal conductivity and the effective viscosity for Maxwell molecules are independent of the heat-flux Knudsen number, and additional DSMC simulations indicate that these transport properties for hard-sphere molecules decrease slightly as the heat-flux Knudsen number is increased. Similarly, the MH and DSMC results indicate that the effective thermal conductivity and the effective viscosity for Maxwell molecules decrease as the shear-stress Knudsen number is increased, and additional DSMC simulations indicate the same behavior for hard-sphere molecules. These results provide strong evidence that the DSMC method can be used to determine the state of a gas under highly nonequilibrium conditions

description: Outfield range pastures with widely dispersed sheep are quite common in Norway, with a summer population of approximately 2.4 million animals. In many areas losses to predators are considerable and identifying efficient mitigating measures against predation is a prime target in nature management. In order to assess economic efficiency, any actual effect of the measure on predation and loss regime must be addressed. One problem with some research is the "scale problem". While sheep outfield home range areas have been measured from 2.2 - 33.8 km2, large carnivores on their ranges might use from several hundred up to even thousands of square kilometres. For lynx (Lynx lynx) the home range varies between 158 and 433 km2, wolverine (Gulo gulo) between 61 and 970 km2 and for the brown bear (Ursus arctos) from 171 to 33,041 km2. Thus there emerges a form of statistical dependence, since the exposure of the carnivores to actions and measures in a sheep home range or sample area might influence how the same carnivores behave outside the area. The external effects on society, the environment or other farmers may therefore outweigh advantages to farmers introducing the measure, and scale evaluation might be of crucial importance in designing field research projects exploring such measures.

description: In 2000 I was awarded a Nuffield Farming Scholarship to study the impact of biotechnology, in particular genetically modified crops, on international agricultural research, production and marketing. I studied this topic in 2001 in Canada, USA and United Kingdom in an attempt to gain an insight into the issues with GM crops and how this may impact on our decision to grow them in Western Australia. I was impressed by the technology available that opened up a range of opportunities for vast improvements in production traits, quality of food, food safety and environmental and human health benefits. I also gained an understanding of the challenges faced by Canada and the US in production, identity preservation, testing and marketing of GM crops. In contrast the UK gave me a valuable appreciation of the influence of the marketplace in determining the future of GM research and production. Since my return I have had an opportunity to reflect on what I learnt and assess the impact this has on our decision to grow GM crops in WA in an environment of growing public concern and debate. The technology provides us with a valuable tool for more efficient production and market segmentation and we must take advantage of it to remain competitive in the world market. However, we need to learn from the mistakes made by other countries producing GM crops and commit resources to very good testing and identity preservation systems backed by strong regulatory, research, development and production processes to minimise the risk of making the same mistakes.

description: We describe the disappearance of a sector of sunspot penumbra and its restoring process observed in the preceding sunspot of active region NOAA 12348. The evolution of the magnetic field and the plasma flows support the idea that the penumbra forms due to a change of inclination of the magnetic field of the canopy. Moving magnetic features have been observed during the disintegration phase of that sector of sunspot penumbra. During the restoring phase we have not observed any magnetic flux emergence around the sunspot. The restoring process of the penumbra sector completed in about 72 hours and it was accompanied by the transition from the counter-Evershed flow to the classical Evershed flow. The inversion of photospheric spectropolarimetric measurements taken by IBIS allowed us to reconstruct how the uncombed configuration of the magnetic field forms during the new settlement of the penumbra, i.e., the vertical component of the magnetic field seems to be progressively replaced by some horizontal field lines, corresponding to the intra-spines.
