description: We study a simple transport model driven out of equilibrium by reservoirs at the boundaries, corresponding to the hydrodynamic limit of the symmetric simple exclusion process. We show that a nonlocal transformation of densities and currents maps the large deviations of the model into those of an open, isolated chain satisfying detailed balance, where rare fluctuations are the time reversals of relaxations. We argue that the existence of such a mapping is the immediate reason why it is possible for this model to obtain an explicit solution for the large-deviation function of densities through elementary changes of variables. This approach can be generalized to the other models previously treated with the macroscopic fluctuation theory.

description: This thesis studies canonical ideals of flat families of curves defined over discrete valuation rings. Such families arise naturally in the context of the problem of lifting curves with automorphisms. We focus our attention on the flat family that unifies Kummer theory and Artin-Schreier theory, also known as Oort-Sekiguchi-Suwa (OSS) theory, defined over a discrete valuation ring that dominates the ring of Witt vectors. In particular, we obtain explicit generators for the relative canonical ideal of Artin-Schreier-Kummer-Witt family and study its syzygies.

description: No abstracts are to be cited without prior reference to the author.Halibut behaviour in net pens has been studied using direct observation, underwater video and/or hydroacoustic equipment Rearing experience includes a wide range of fish weights (50-10.000 g) and fish densities (4-150 kg/m2). Individual halibut is able to change their coloration on the ocular side from their white­spotted benthic camouflage to the uniformly brown-grey pelagic camouflage within a minute and vice-a-versa. The proportion of fish with pelagic camouflage on/near the bottom was high in the net pens with high densities, and such groups also showed suboptimal growth. The results also indicated an increase in pelagic swimming activity in the net pens with the highest densities. High light levels and low temperatures decreased the pelagic swimming activity of the fish. Halibut in net pens reared at low densities did not spread evenly on the bottom, but were usually found in clumps.

description: No abstracts are to be cited without prior reference to the author.The spotted wolffish (Anarhichas minor Olafsen), with its rich and tasteful filets, popular skin and high growth rates in captivity is a promising candidate for cold-water aquaculture. We have established a small scale production line for spotted wolffish during five years of active research on the biology of the species. Our broodstock sampled from the Barents Sea has gone through an annual reproductive cycle at the ambient sea temperatures at our research station as well as at a recently established commercial production facility, and have spawned from August to January. The females must be stripped as. soon• as possible after ovulation and intensive guarding of potential spawners is required. Late in the spawning season it has been difficult to find spermiating males, and for practical purposes cryopreservation of sperm would be useful in future large-scale production systems. Good egg batches have shown c. 100 % fertilization and survival rates between 60 and 80 % during the 800 to 960 day degrees incubation period which varied with temperature. Rearing temperatures of 6 and 8 °C and ambient, decreasing temperatures have turned out to be satisfactory for survival. Treatment with 150 ppm glutaraldehyde twice a month is recommended to control microorgansim growth. Some problems have been noted with regard to. too early hatching in individual egg batches, the reasons are not fully understood. Normally hatched individuals are c. 22 mm long and well-developed, with a small yolk sac which is completely resorbed after c. four weeks. The fry has been successfully startfed on formulated feed as well as Artemia. Highest early growth rates have been noted at 8 °C. Mortality peaked after 30 days, i.e. after the final phase of yolk resorption and dissappearance of starving individuals, and was negligible thereafter. On-growth of spotted wolffish juveniles fed formulated dry floating feed at low temperatures in shallow raceway.systems has been promising. After two, three and four years the mean weights were 1, 3 and 5 kilos respectively. Cultivated spotted wolffish do not appear to mature earlier than reported from wild populations

description: Distribution of the entangled state of trapped atomic ions to long distance using quantum repeater protocol is considered. Indeed, the long distance is divided into short parts, and then using entanglement generation and entanglement swapping techniques in optomechanical cavities, the entanglement is distributed. To do the task, we perform interaction between trapped atomic ions in optomechanical cavities, operate proper measurements on trapped ions and also make Bell state measurement as a well-known way to swap the entanglement. Accordingly, the entanglement is distributed between target ions with satisfactory values of success probability and entanglement degree. The effects of detuning and amplitude of pump laser on the entanglement and success probability are evaluated. The uctuations of entanglement and success probability are decreased by increasing of detuning. Via increasing the amplitude of pump laser, the maxima of entanglement are repeated more times and success probability undergoes the collapse-revival phenomenon.
A Temporal Logic for Asynchronous Hyperproperties

description: Hyperproperties are properties of computational systems that require more than one trace to evaluate, e.g., many information-flow security and concurrency requirements. Where a trace property defines a set of traces, a hyperproperty defines a set of sets of traces. The temporal logics HyperLTL and HyperCTL* have been proposed to express hyperproperties. However, their semantics are synchronous in the sense that all traces proceed at the same speed and are evaluated at the same position. This precludes the use of these logics to analyze systems whose traces can proceed at different speeds and allow that different traces take stuttering steps independently. To solve this problem in this paper, we propose an asynchronous variant of HyperLTL. On the negative side, we show that the model-checking problem for this variant is undecidable. On the positive side, we identify a decidable fragment which covers a rich set of formulas with practical applications. We also propose two model-checking algorithms that reduce our problem to the HyperLTL model-checking problem in the synchronous semantics.
In-plane critical magnetic fields in magic-angle twisted trilayer graphene

description: It has recently been shown that superconductivity in magic-angle twisted trilayer graphene survives to in-plane magnetic fields that are well in excess of the Pauli limit, and much stronger than the in-plane critical magnetic fields of magic-angle twisted bilayer graphene. The difference is surprising because twisted bilayers and trilayers both support the magic-angle flat bands thought to be the fountainhead of twisted graphene superconductivity. We show here that the difference in critical magnetic fields can be traced to a $\mathcal{C}_2 \mathcal{M}_{h}$ symmetry in trilayers that survives in-plane magnetic fields, and also relative displacements between top and bottom layers that are not under experimental control at present. An gate electric field breaks the $\mathcal{C}_2 \mathcal{M}_{h}$ symmetry and therefore limits the in-plane critical magnetic field.

Detecting dark energy with wavelets on the sphere

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: Dark energy dominates the energy density of our Universe, yet we know very little about its nature and origin. Although strong evidence in support of dark energy is provided by the cosmic microwave background, the relic radiation of the Big Bang, in conjunction with either observations of supernovae or of the large scale structure of the Universe, the verification of dark energy by independent physical phenomena is of considerable interest. We review works that, through a wavelet analysis on the sphere, independently verify the existence of dark energy by detecting the integrated Sachs-Wolfe effect. The effectiveness of a wavelet analysis on the sphere is demonstrated by the highly statistically significant detections of dark energy that are made. Moreover, the detection is used to constrain properties of dark energy. A coherent picture of dark energy is obtained, adding further support to the now well established cosmological concordance model that describes our Universe.

Some mechanisms of transverse nuclear magnetic relaxation in model membranes
Creators: name: Sternin, Edward
Publisher: name: University of British Columbia
Year: 2010

description: Experimental proof is presented that some of the motions responsible for transverse relaxation (T₂) in deuterium magnetic resonance (²H NMR) experiments on acyl chains of a model membrane in the liquid crystalline phase are extremely slow on the ²H NMR time scale being characterized by a correlation time T₂ > ѡq⁻¹. The experiments used to investigate these slow motions involve a form of the Carr-Purcell-Meiboom-Gill pulse sequence modified so as to be suitable for ²H NMR (q-CPMG). The most plausible mechanism responsible for T₂ relaxation is the gradual change in the average molecular orientation due to lateral diffusion of the phospholipid molecules along curved membrane surfaces. Presence of such diffusion is directly established by a selective inversion recovery experiment in which magnetization transfer across the spectrum is seen. The results of the T₂ relaxation as measured in the q-CPMG experiments are fitted to an average correlation time, T₂ ≈ 62 ms, yielding an estimate of the average effective radius of curvature of 1.2 µm for a typical model membrane system, in good agreement with other methods of measurement. The implications of this main result are examined for a number of model membranes; in particular, considerable changes are seen in the character of molecular motions in systems containing small concentrations of sterols. Similarly, changes caused by the topological differences between the lamellar L∝ and hexagonal H₁₁ phases are examined in a model membrane system which undergoes a L∝ to H₁₁ phase transition. A novel way of quantifying the differences in the orientational order parameters across the phase transition is used; the observed differences are consistent with the different symmetry properties of the two phases. Perdeuteriated polycrystalline hexamethylbenzene is used to demonstrate various methods of measuring ²H NMR relaxation. In addition, some aspects of orientation dependence of the relaxation rates are examined, and found to agree with the theory.

description: No abstracts are to be cited without prior reference to the author.There has been a great increase in production of marine fish species during the last 20 years, mainly activity from landbased farms or small cages close to land. A landbased plant require large investment and labour costs. The availability of useful land area may be restricted. When the production of marine species increase, the price of the product decrease and this require a reduction in the total production costs. As a result, marine fish farming linked to cage culture in sea is expected to increase in the future. The farming of salmon is an example of a modern cage culture in fish farming. This industry has a 30 year's old history, from a fumbling start with small wooden structures to today's giant units like oil platforms. The technological improvements for cages was essential, but several developments are essential such as environment, feeding, health and fish farming management. A modern cage farming is illustrated with an increase fish production, decreasing production costs, high quality of slaughtered fish and a close control of the marine environment. There is a very clear tendency to make use of deep floating cages covering a huge volume of water. The industry world-wide is expected to produce 700 thousands tons of Atlantic salmon this year, with half of the production coming from Norway. The forecast for the year 2010 is 1.9 million tonnes of Atlantic salmon.

description: This paper sets out a robust methodology for modelling spectra of polyatomic molecules produced in reactive or dissociative environments, with vibrational populations outside local thermal equilibrium (LTE). The methodology is based on accurate, extensive ro-vibrational line lists containing transitions with high vibrational excitations and relies on the detailed ro-vibrational assignments. The developed methodology is applied to model non-LTE IR and visible spectra of silylene (SiH$_2$) produced in a decomposition of disilane (Si$_2$H$_6$), a reaction of technological importance. Two approaches for non-LTE vibrational populations of the product SiH$_2$ are introduced: a simplistic 1D approach based on the Harmonic approximation and a full 3D model incorporating accurate vibrational wavefunctions of SiH$_2$ computed variationally with the TROVE (Theoretical ROVibrational Energy) program. We show how their non-LTE spectral signatures can be used to trace different reaction channels of molecular dissociations.

description: No abstracts are to be cited without prior reference to the author.The idea to feed predatory fish to enhance fisheries yield is introduced and evaluated for the Icelandic cod stock. The benefit from large-scale feeding may be two-fold. First, it may increase the growth rate of a predatory fish stock. Second, it may reduce cannibalism and predation on valuable species. For a large part of the year there is limited overlap in the distribution of the Icelandic cod stock and adult capelin, its principal prey. This may result in starvation, reduced growth, cannibalism and predation on expensive prey. For large-scale feedingto be economically feasible it is necessary to have access to large quantities of inexpensive feed and an efficient feeding technique. In Iceland about 1 million tons of capelin' and herring are landed annually for fishmeal production. It seems likely that the basic feeding technique used in a small-scale feeding experiment in an Icelandic fjord can be scaled up for large­scale feeding. Five different feeding scenarios and the research required for. feasibility assessment are considered for the Icelandic cod stock.

description: We present HI observations of the edge-on galaxy NGC 891. These are among the deepest ever performed on an external galaxy. They reveal a huge gaseous halo, much more extended than seen previously and containing almost 30 % of the HI. This HI halo shows structures on various scales. On one side, there is a filament extending (in projection) up to 22 kpc vertically from the disk. Small (M_HI ~ 10^6 Msol) halo clouds, some with forbidden (apparently counter-rotating) velocities, are also detected. The overall kinematics of the halo gas is characterized by differential rotation lagging with respect to that of the disk. The lag, more pronounced at small radii, increases with height from the plane. There is evidence that a significant fraction of the halo is due to a galactic fountain. Accretion from intergalactic space may also play a role in building up the halo and providing low angular momentum material needed to account for the observed rotation lag. The long HI filament and the counter-rotating clouds may be direct evidence of such accretion.

description: Antibacterial micron-sized cryogels, so-called microcryogels, were prepared by cryogelation of gelatin and integration of lysozyme. Gelation yield, specific surface area, macro-porosity and swelling degree of the microcryogels were examined in order to characterize their physical properties. MTT method was utilized to measure cell viability of the gelatin microcryogels with a period of 24, 48, and 72 h and no significant decrease was observed at 72 h. Apoptotic staining assay also showed high viability at 24, 48, 72 h in parallel with the control group. The antibacterial performances of the gelatin microcryogels against Bacillus subtilis, Staphylococcus aureus, and Escherichia coli were examined. The results showed that the incorporation of lysozyme into gelatin microcryogels exhibited the antibacterial activity against S. aureus, B. subtilis, and E. coli, that may provide great potential for various applications in the biomedical industry.

description: In this paper at first we successfully teleport the unknown quantum state which is a superposition of squeezed vacuum state and squeezed one-photon state using the beam splitter in the absence of dissipation. In the continuation, we try to implement the same teleportation protocol, however, in the presence of dissipation effects. To do this task, we use proper entangled channel to reach to perfect teleportation under the in uence of decoherence. Finally, we consider another superposition of two squeezed vacuum states with separation in phase and teleport it with a different appropriate entangled channel. In fact, we will observe that, one can successfully teleport the considered superposition of squeezed states by choosing proper entangled channels in the presence and absence of dissipation in appropriate chosen conditions.

description: Strong evidence for the presence of a warped Keplerian accretion disc in NGC4258 (M 106) has been inferred from the kinematics of water masers detected at sub-parsec scales. Assuming a power-law accretion disc and using constraints on the disc parameters derived from observational data, we have analyzed the relativistic Bardeen-Petterson effect driven by a Kerr black hole as the potential physical mechanism responsible for the disc warping. We found that the Bardeen-Petterson radius is comparable to or smaller than the inner radius of the maser disc (independent of the allowed value for the black hole spin parameter). Numerical simulations for a wide range of physical conditions have shown that the evolution of a misaligned disc due to the Bardeen-Petterson torques usually produces an inner flat disc and a warped transition region with a smooth gradient in the tilt and twist angles. Since this structure is similar to that seen in NGC 4258, we propose that the Bardeen-Petterson effect may be responsible for the disc warping in this galaxy. We estimated the time-scale necessary for the disc inside of the Bardeen-Petterson radius to align with the black hole's equator, as a function of the black hole spin. Our results show that the Bardeen-Petterson effect can align the disc within a few billion years in the case of NGC 4258. Finally, we show that if the observed curvature of the outer anomalous arms in the galactic disc of NGC 4258 is associated with the precession of its radio jet/counterjet, then the Bardeen-Petterson effect can provide the required precession period.

description: In this paper we consider the quantum repeater protocol for distributing the entanglement to two distant three-level atoms. In this protocol, we insert six atoms between two target atoms such that the eight considered atoms are labeled by 1; 2;... 8, while only each two adjacent atoms (i; i + 1) with i = 1; 3; 5; 7 are entangled. Initially, the separable atomic pair states (1,4) and (5,8) become entangled by performing interaction between atoms (2,3) and (6,7) in two optomechanical cavities, respectively. Then, via performing appropriate interaction between atoms (4,5) in an optical cavity quantum electrodynamics (QED) approach, the target atoms (1,8) are finally become entangled. Throughout this investigation, the effects of mechanical frequency and optomechanical coupling strength to the field modes on the produced entanglement and the related success probability are evaluated. It is shown that, the time period of produced entanglement can be developed by increasing the mechanical frequency. Also, maximum of success probability of atoms (1,8) is increased by decreasing the optomechanical coupling strength to the field modes in most cases.

Οι παράμετροι που μελετήθηκαν συμπεριλαμβάνουν την εωσινοφιλία, τα επίπεδα της ολικής IgE στο αίμα, και τα επίπεδα των ιντερλευκινών (IL) 16, 17A και 23 στο περιφερικό αίμα και στον ορό της πομφόλυγας. Τριάντα ασθενείς πληρούν τα κριτήρια ένταξης στη μελέτη. Οι ασθενείς με υψηλά επίπεδα IgE έχουν σημαντικά υψηλότερα επίπεδα IL17A και σε φυσιολογικά πλαίσια επίπεδα IL23 στο αίμα και στον ορό της πομφόλυγας. Οι ασθενείς με φυσιολογικά επίπεδα IgE έχουν ελαφρώς ψηλότερα επίπεδα IL23 στο αίμα και στον ορό της πομφόλυγας. Η εωσινοφιλία σχετίζεται θετικά με τα επίπεδα της IL17A στο αίμα και αρνητικά με τα επίπεδα της IL23. Τα επίπεδα της IL16 δε διαφέρουν στις δύο ομάδες. Οι ασθενείς με ΠΠ θα μπορούσαν να επωφεληθούν από την πρόσθεση των μη ανοσοκαταλτικών θεραπειών στα ενδεδειγμένα θεραπευτικά σχήματα για τη δερματική τους νόσο.
description: Bullous pemphigoid (BP) patients are predominantly above 70 years of age, with limited tolerance to the side effects of the immunosuppressive drugs. Advancements in our understanding of the pathophysiology of BP have led to the development of molecules which target specific pathways involved in induction and perpetuation of disease. Patients with BP Disease Area Index above 60 and less than 100 were split into two groups – one with high and the other with normal levels of IgE. The tested parameters included eosinophils’ count, total IgE serum level and interleukins (IL) 16, 17A and 23 counts in the peripheral blood and skin bulla serum, before any therapeutic intervention. Thirty individuals fulfilled the criteria for enrollment. Patients with high IgE blood serum levels had significantly higher levels of IL17A and normal IL23 levels in blood and bulla serum. Patients with normal serum IgE levels had slightly higher IL23 levels in blood and bulla serum. The eosinophil count was positively related to IL17 blood serum level and negatively related to IL23. IL16 did not differ in the two groups. BP patients may represent a group of patients benefiting most substantially from the introduction of non-immunosuppressive therapeutics into the treatment regimens for their disease.

description: We have examined whether the Co ions crystallographically substitute on the Ti sites in rutile and anatase Ti_{1-x}$Co$_{x}$O$_{2-delta}$ thin films that exhibit room-temperature ferromagnetism. Intensities of the x-ray Bragg reflection from the films were measured around the $K$-absorption-edge of Co. If the Co ions randomly substitute on the Ti sites, the intensity should exhibit an anomaly due to the anomalous dispersion of the atomic scattering factor of Co. However, none of the anatase and rutile samples did exhibit an anomaly, unambiguously showing that the Co ions in Ti$_{1-x}$Co$_{x}$O$_{2-delta}$ are not exactly located at the Ti sites of TiO$_2$. The absence of the anomaly is probably caused by a significant deformation of the local structure around Co due to the oxygen vacancy. We have applied the same method to paramagnetic Zn$_{1-x}$Co$_{x}$O thin films and obtained direct evidence that the Co ions are indeed substituted on the Zn sites.

description: A periodic structure sandwiched between two homogeneous media can support bound states in the continuum (BICs) that are valuable for many applications. It is known that generic BICs in periodic structures with an up-down mirror symmetry and an in-plane inversion symmetry are robust with respect to structural perturbations that preserve these two symmetries. For two-dimensional (2D) structures with one periodic direction and the up-down mirror symmetry (without the in-plane inversion symmetry), it was recently established that some scalar BICs can be found by tuning a single structural parameter. In this paper, we analyze vectorial BICs in such 2D structures, and show that a typical vectorial BIC with nonzero wavenumbers in both the invariant and the periodic directions can only be found by tuning two structural parameters. Using an all-order perturbation method, we prove that such a vectorial BIC exists as a curve in the 3D space of three generic parameters. Our theory is validated by numerical examples involving periodic arrays of dielectric cylinders. The numerical results also illustrate the conservation of topological charge when structural parameters are varied, if both BICs and circularly polarized states (CPSs) are included. Our study reveals a fundamental property of BICs in periodic structure and provides a systematically approach for finding BICs in structures with less symmetry.

Radiation transport in laser-matter interactions

description: The details of x-ray emission and transport in laser-matter interactions are currently of great interest. We have irradiated aluminum targets with 0.53 μm laser light in a ~ 2 ns (FWHM) pulse at an absorbed irradiance of Φ[sub L] = 2.3 x 10¹³ W/cm² . The temporal evolution of the ii"—shell photoabsorption edge of shock compressed aluminum was measured with an x-ray streak camera. The experimental results were found to be in reasonable agreement with the predictions of our one-dimensional hydrocode (HYRAD) which includes detailed calculation of radiation emission and transport. The effects of a finite focal spot on the K-edge profile were also assessed using a simplified two-dimensional hydrocode. The results suggest that the measured edge broadening is a consequence of non-uniform target conditions. Further numerical simulations using HYRAD verified the importance of K[sub α] emission spectrum in studying the effects of radiation transport. However, these predictions were found to be in significant disagreement with our experimental measurements of the time resolved K[sub α]emission spectrum. One possible explanation for this discrepancy is an underestimate of the K[sub α] fluorescent yield for certain ion species of aluminum. The reason for this is the generation of excited states which can not decay through the Auger process. Nevertheless, the experimental results still show characteristics of the radiatively heated zone predicted by the hydrocode.

title: Nuclear-Free Wales and the ‘anti-Thatcher Alliance’: Political Culture and Anti-Nuclear Protest in Wales during the 1980s
Creators: name: Bryant, Gareth
Publisher: name: The Open University
Year: 2025

description: This thesis examines anti-nuclear protest in Wales as a national movement, exploring its relationship to the UK-wide anti-nuclear movement and its impact on Welsh political culture in the lead up to devolution. I have presented the first detailed institutional history of CND Cymru, the Welsh Anti-Nuclear Alliance (WANA) and the campaign for a Nuclear-Free Wales, based upon original research. It explores the role of these movements in facilitating cross-community support for the creation of the Senedd Cymru in 1999 and their interaction with the Labour and Plaid Cymru political traditions. The thesis also considers the role of opposition to Conservative Prime Minister Margaret Thatcher in unifying Welsh national feeling, partly expressed through extra-parliamentary campaigns such as those against nuclear arms and power. My research demonstrates the ways in which social movements such as CND Cymru and WANA created space for collaboration and discussion across traditional divides during turbulent times in Welsh society.

description: We consider dynamics of the FRW Universe with a scalar field. Using Maupertuis principle we find a curvature of geodesics flow and show that zones of positive curvature exist for all considered types of scalar field potential. Usually, phase space of systems with the positive curvature contains islands of regular motion. We find these islands numerically for shallow scalar field potentials. It is shown also that beyond the physical domain the islands of regularity exist for quadratic potentials as well.

description: No abstracts are to be cited without prior reference to the author. We discuss the possibilities and limitations of extensive aquaculture of marine fish based on the results from a programme that has evaluated the enhancement of local coastal cod ( Gadus morhua L.) stocks in Norway. The cod enhancement programme has investigated the effects on ecosystems of releases of large numbers of cod juveniles, the carrying and production capacity for cod, and mortality, migration, feeding and growth of released and wild cod. The importance of different management, ecosystem and species characteristics for the outcome of enhancement experiments is evaluated. Suggestions are made for future investigations of enhancement potential of marine fish stocks in Norway and other areas, both with regard to experimental logistics and choice of species.

description: The linear-quadratic (LQ) model to describe the survival of irradiated cells may be the most frequently used biomathematical model in radiotherapy. There has been an intense debate on the mechanistic origin of the LQ model. An interesting approach is that of obtaining LQ-like behavior from kinetic models, systems of differential equations that model the induction and repair of damage. Development of such kinetic models is particularly interesting for application to continuous dose rate therapies, such as molecular radiotherapy or brachytherapy. In this work, we present a simple kinetic model that describes the kinetics of populations of tumor cells, rather than lethal/sub-lethal lesions, which may be especially useful for application to continuous dose rate therapies, as in molecular radiotherapy. The multi-compartment model consists of a set of three differential equations. The model incorporates in an easy way different cross-interacting compartments of cells forming a tumor, and may be of especial interest for studying dynamics of treated tumors. In the fast dose delivery limit, the model can be analytically solved, obtaining a simple closed-form expression. Fitting of several surviving curves with both this solution and the LQ model shows that they produce similar fits, despite being functionally different. We have also investigated the operation of the model in the continuous dose rate scenario, firstly by fitting pre-clinical data of tumor response to 131I-CLR1404 therapy, and secondly by showing how damage repair and proliferation rates can cause a treatment to achieve control or not. Kinetic models like the one presented in this work may be of special interest when modeling response to molecular radiotherapy.
