description: The magnetic field dependence of the magnetisation ($M$) and the temperature dependence of the ac susceptibility ($χ' = dM/dH$) of CePd(1-x)Rh(x) single crystals with $0.80 \leq x \leq 0.86$ are analysed within the frame of the quantum Griffiths phase scenario, which predicts $M \propto H^λ$ and $χ' \propto T^{λ-1}$ with $0 \leq λ\leq 1$. All $M$ vs $H$ and $χ'$ vs $T$ data follow the predicted power-law behaviour. The parameter $λ$, extracted from $χ'(T)$, is very sensitive to the Rh content $x$ and varies systematically with $x$ from -0.1 to 0.4. The value of $λ$, derived from $M(H)$ measurements on a \cpr single crystal, seems to be rather constant, $λ\approx 0.2$, in a broad range of temperatures between 0.05 and 2 K and fields up to about 10 T. All observed signatures and the $λ$ values are thus compatible with the quantum Griffiths scenario.

description: We study the evolution of magnetized and rigidly rotating neutron stars within a fully general relativistic implementation of ideal magnetohydrodynamics with no assumed symmetries in three spatial dimensions. The stars are modeled as rotating, magnetized polytropic stars and we examine diverse scenarios to study their dynamics and stability properties. In particular we concentrate on the stability of the stars and possible critical behavior. In addition to their intrinsic physical significance, we use these evolutions as further tests of our implementation which incorporates new developments to handle magnetized systems.

description: MIGHTEE is a galaxy evolution survey using simultaneous radio continuum, spectro-polarimetry, and spectral line observations from the South African MeerKAT telescope. When complete, the survey will image $\sim$20 deg$^{2}$ over the COSMOS, E-CDFS, ELAIS-S1, and XMM-LSS extragalactic deep fields with a central frequency of 1284 MHz. These were selected based on the extensive multiwavelength datasets from numerous existing and forthcoming observational campaigns. Here we describe and validate the data processing strategy for the total intensity continuum aspect of MIGHTEE, using a single deep pointing in COSMOS (1.6 deg$^{2}$) and a three-pointing mosaic in XMM-LSS (3.5 deg$^{2}$). The processing includes the correction of direction-dependent effects, and results in thermal noise levels below 2~$\mathrmμ$Jy beam$^{-1}$ in both fields, limited in the central regions by classical confusion at $\sim$8$''$ angular resolution, and meeting the survey specifications. We also produce images at $\sim$5$''$ resolution that are $\sim$3 times shallower. The resulting image products form the basis of the Early Science continuum data release for MIGHTEE. From these images we extract catalogues containing 9,896 and 20,274 radio components in COSMOS and XMM-LSS respectively. We also process a close-packed mosaic of 14 additional pointings in COSMOS and use these in conjunction with the Early Science pointing to investigate methods for primary beam correction of broadband radio images, an analysis that is of relevance to all full-band MeerKAT continuum observations, and wide field interferometric imaging in general. A public release of the MIGHTEE Early Science continuum data products accompanies this article.

description: Investigations of isotope shifts of atomic spectral lines provide insights into nuclear properties. Deviations from the linear dependence of the isotope shifts of two atomic transitions on nuclear parameters, leading to a nonlinearity of the so-called King plot, are actively studied as a possible way of searching for the new physics. In the present work we calculate the King-plot nonlinearities originating from the Standard-Model atomic theory. The calculation is performed both analytically, for a model example applicable for an arbitrary atom, and numerically, for one-electron ions. It is demonstrated that the Standard-Model predictions of the King-plot nonlinearities are hypersensitive to experimental errors of nuclear charge radii. This effect significantly complicates identifications of possible King-plot nonlinearities originating from the new physics.

description: The attachment of well-defined charge transfer agents to the surface of nanomaterials is an efficient strategy to control their charge density and also to tune their optical, electrical, and physicochemical properties. Particularly interesting are charge transfer agents that either donate or withdraw electrons depending on the arrangements of their building units and that promise a non-destructive attachment to delicate nanomaterials like sp$^2$ compounds. In this work, we rationally synthesize molecular moieties with versatile functionalities. A reactive anchor group allows to attach them to carbon nanotubes as defined charge transfer agents while preserving the tube $π$-conjugation. The charge transfer agents were synthesized through the stepwise nucleophilic substitution of either one (monosubstituted series) or two chlorine (disubstituted series) atoms of cyanuric chloride by aniline derivatives containing one, two or three methoxy groups in the para and meta positions. Variation in the number and position of methoxy as an electron transferring group help us to manipulate the electronic and optical properties of the molecular probes and their charge transfer to the SWNTs systematically. The correlation between the optical properties of these molecular probes and their functionality was investigated by experiments and quantum chemical calculations. While the optoelectronic properties of the conjugated charge transfer agents were dominated by the aniline segments, the triazine warrants the ability to nondestructively attach to the surface of SWNTs. This study is one step ahead towards the production of SWNTs with desired optical and electrical properties by covalent $π$-preserving functionalization.

description: The DOMON domain is a domain widespread in nature, predicted to fold in a β-sandwich structure. In plants, AIR12 is constituted by a single DOMON domain located in the apoplastic space and is GPI-modified for anchoring to the plasma membrane. Arabidopsis thaliana AIR12 has been heterologously expressed as a recombinant protein (recAtAIR12) in Pichia pastoris. Spectrophotometrical analysis of the purified protein showed that recAtAir12 is a cytochrome b. RecAtAIR12 is highly glycosylated, it is reduced by ascorbate, superoxide and naftoquinones, oxidised by monodehydroascorbate and oxygen and insensitive to hydrogen peroxide. The addition of recAtAIR12 to permeabilized plasma membranes containing NADH, FeEDTA and menadione, caused a statistically significant increase in hydroxyl radicals as detected by electron paramagnetic resonance. In these conditions, recAtAIR12 has thus a pro-oxidant role. Interestingly, AIR12 is related to the cytochrome domain of cellobiose dehydrogenase which is involved in lignin degradation, possibly via reactive oxygen species (ROS) production.  In Arabidopsis the Air12 promoter is specifically activated at sites where cell separations occur and ROS, including •OH, are involved in cell wall modifications.  air12 knock-out plants infected with Botrytis cinerea are more resistant than wild-type and air12 complemented plants. Also during B. cinerea infection, cell wall modifications and ROS are involved. Our results thus suggest that AIR12 could be involved in cell wall modifying reactions by interacting with ROS and ascorbate.
CyDOMs are plasma membrane redox proteins of plants that are predicted to contain an apoplastic DOMON fused with a transmembrane cytochrome b561 domain. CyDOMs have never been purified nor characterised. The trans-membrane portion of a soybean CyDOM was expressed in E. coli but purification could not be achieved. The DOMON domain was expressed in P. pastoris and shown to be itself a cytochrome b that could be reduced by ascorbate.
Characterization of new molecular targets involved in iodide flux in the thyroid gland: the anoctamins

description: Iodide transport is necessary for the synthesis of thyroid hormones following accumulation in the follicular lumen out of thyroid cells, via channels unknown with the exception of pendrin.  
 According to our hypothesis, TMEM16A could be the main molecular identity of the channel mediating iodide efflux in the thyroid gland. TMEM16A is the prior candidate for calcium-activated chloride conductance (CaCC). TMEM16A belongs to the TMEM16/anoctamin family comprising ten members (TMEM16A-K). Higher affinity of TMEM16A for iodide and predicted expression in the thyroid gland suggest its mediation of iodide efflux.
 The aim of this project was to identify the role of TMEM16A in iodide transport in the thyroid gland, by characterizing its molecular expression and functional properties. 
 We demonstrated that TMEM16F, H, K transcripts are expressed in FRTL-5 thyroid cells, as well as TMEM16A, which is TSH-independent. Tumor tissue from human thyroid maintains TMEM16A expression. 
 Functional in vivo experiments in FRTL-5, stably expressing YFP-H148Q/I152L fluorescent protein as a biosensor, showed that iodide efflux is stimulated by agonists of purinergic receptors with an order of potency of ATP>UTP>ADP (compatible with an involvement of P2Y purinergic receptors), and by agonists of adrenergic receptors (epinephrine, norepinephrine and phenylephrine). Iodide efflux was blocked by α-receptor antagonists prazosin and phentolamine, consistent with a role of α1 adrenergic receptors. Iodide efflux was specifically dependent on calcium mobilized from intracellular compartments and induced by the calcium ionophore ionomycin. CaCC blockers suppressed ionomycin-/ATP-/epinephrine-stimulated iodide efflux.
   Heterologous expression of TMEM16A in CHO K1 cells induced calcium-activated iodide fluxes.
 All these results support the hypothesis of the involvement of TMEM16A in calcium-dependent iodide efflux induced by receptor agonists in thyroid cells. TMEM16A may represent a new pharmacological target for thyroid cancer therapy, since its blockade may enhance the retention of radioiodide by tumour cells enhancing the efficacy of radioablative therapy.

description: The appearance of the big bounce (BB) in the evolution of the universe is analyzed in the setting of loop quantum cosmology (LQC). Making use of an idea of a minimum length turns classical Big Bang into BB. We argue why the spectrum of the kinematical area operator of loop quantum gravity cannot be used for the determination of this length. We find that the fundamental length, at the present stage of development of LQC, is a free parameter of this model.

By using the $\bar{Q}$ equations, we compute the symbol of the first MHV amplitude with algebraic letters -- the three-loop 8-point amplitude (or the octagon remainder function) -- in this theory. The symbol alphabet for this amplitude consists of 204 independent rational letters and shares the same 18 algebraic letters with the two-loop 8-point NMHV amplitude.

Environmental influences on the pulmonary manifestations of Cystic Fibrosis
Creators: name: Murrin, Olivia
Publisher: name: Imperial College London
Year: 2022

description: Cystic fibrosis is a multisystemic monogenic disease with many severe symptoms and complications, primarily in the respiratory and digestive systems. Medical advances have greatly extended the survival of patients with the disease. In parallel population expansion and globalisation have increased exposure to pollution. CF care is managed in specialist centres located in major cities. This PhD examines the relationship between the environment and the pulmonary manifestations of CF.1) A systematic review of environmental factors and cystic fibrosis covers the current literature interrogating factors best modified by policy. 2) I analyse the effect of distance from the attended CF centre on lung function and frequency of exacerbations using multivariate regression. 3) I compare Hospital episode statistics to the CF Registry to investigate for temporal and spatial accuracy. 4) A time series analysis analyses the short-term relationship between air pollution and pulmonary exacerbations using a distributed lag nonlinear model (DLNM). Environmental factors may have an impact on lung health through modulation of infection as well as direct oxidative damage to the lung. Those with a more severe genotype are more likely to bypass their nearest centre and travel further to reach care. Even when accounting for this, bypassing the nearest centre is associated with decreased lung function in older adults. Those in urban areas are more likely to receive IVs in hospitals than at home. Improving and supporting access to home IV therapy could aid demands on specialist care. Temporal data could be improved to allow if linkage was allowed. Particulate matter may increase the risk of hospitalisation with an exacerbation. Patients may compete for specialist beds in London on days with high air pollution. Overall, this thesis shows modifiable environmental factors in CF intersect with healthcare delivery.

description: The structure, and electrical, mechanical and optical properties of few-layer graphene (FLG) synthesized by chemical vapor deposition (CVD) on a Ni coated substrate were studied. Atomic resolution transmission electron microscope (TEM) images show highly crystalline single layer parts of the sample changing to multilayer domains where crystal boundaries are connected by chemical bonds. This suggests two different growth mechanisms. CVD and carbon segregation participate in the growth process and are responsible for the different structural formations found. Measurements of the electrical and mechanical properties on the centimeter scale provide evidence of a large scale structural continuity: 1) in the temperature dependence of the electrical conductivity, a non-zero value near 0 K indicates the metallic character of electronic transport; 2) the Young's modulus of a pristine polycarbonate film (1.37 GPa) improves significantly when covered with FLG (1.85 GPa). The latter indicates an extraordinary Young modulus value of the FLG-coating of TPa orders of magnitude. Raman and optical spectroscopy support the previous conclusions. The sample can be used as a flexible and transparent electrode and is suitable for special membranes to detect and study individual molecules in high resolution TEM.
Formulation of a visual stimuli kit designed as an aid to developing visual awareness for grade 3, 4 and 5 school children by the elementary classroom teacher

description: Formulation of a Visual Stimuli Kit designed as an aid to developing Visual Awareness for Grade 3, 4, and 5 school children by the elementary classroom teacher. In the elementary school, perception is important in many areas of the curriculum. Contemporary art education theorists have become more concerned with the development of children's visual perception as an integral part of the art program. Although there are adequate books and periodicals for teachers about art education theory and method, there is a lack of useful, easily understood, simple to use visual aids. This researcher's aim was to provide the means for teachers to develop perception with the help of visual aids. This kit was designed in such a way as to be easily used by the generalist classroom teacher without specialist training in art, or art education. After reviewing literature in the general area of visual perception and when selecting images for the kit, the researcher believed that two considerations were of paramount importances the relation of the image to the child's own environment; and the relation of the image to the interests of children. Consideration was given not only to the image but to the relationship between two views of the same object. The views of two independent evaluators were sought for clarification of and assessment of the potential kit. The potential kit was composed of black and white, 11" x 14" prints made after taking photographs of environmental areas and articles considered generally interesting to children and adults. An examination revealed that many prints were unsuitable for various reasons. The researcher also found that many needed modification because of insufficient content for detailed analysis. Additional enlarged photographs were made and included in each set. Questions were compiled and photographs were mounted in preparation for pilot testing. Pilot testing was undertaken with a grade 4 and a grade 5 class from two public schools in Vancouver. Visuals were shown and questions were asked about each. Responses were recorded and analysed. It was concluded that the Visual Stimuli Kit would be suitable for further use with only one visual omitted. Previous testing had suggested reportable differences in overall thinking and perception between grade k and grade 5. Large differences were revealed in degree of perception and children's critical thinking. Further testing was carried out with grade 3, 4 and 5 children with responses tabulated and analysed. Grade 4 children with previous perceptual training showed differences in quality of responses. Results from classroom testing gave positive indications of the suitability of the Visual Stimuli Kit for classroom use.

description: It has been shown that Friedmann equation of FRW universe can be derived from the first law of thermodynamics in Einstein gravity, Gauss-Bonnet gravity, Lovelock gravity, scalar-tensor gravity and $f(R)$ gravity. Moreover, it was pointed out that the temperature of the apparent horizon can be obtained using the tunneling formalism for the corresponding observers defined by Kodama vector. In this article, we find that the energy flux through the apparent horizon can be determined by using the Kodama vector. This implies the fact that the Clausius relation and the first law of thermodynamics associated with the apparent horizon in FRW universe is relative to the Kodama observers.We illustrate the derivation of Friedmann equation, and also extend the study to the cases of Hořava-Lifshitz gravity and IR modified Hořava-Lifshitz gravity.

description: We report our ongoing search for extremely inverted spectrum compact radio galaxies, for which the defining feature in the radio spectrum is not the spectral peak, but instead the slope of the spectrum (alpha) in the high-opacity (i.e., lower frequency) part of the radio spectrum. Specifically, our focus is on the spectral regime with spectral index, alpha >+2.5. The motivation for our study is, firstly, extragalactic sources with such extreme spectral index are extremely rare, because of the unavailability of right combination of sensitivity and resolution over a range of low frequencies. The second reason is more physically motivated, since alpha = +2.5 is the maximum slope theoretically possible for a standard radio source emitting synchrotron radiation. Therefore such sources could be the test-bed for some already proposed alternative scenarios for synchrotron self-absorption (SSA), like the free-free absorption (FFA) highlighting the importance of jet-ISM interaction in the radio galaxy evolution.

Linguistic considerations of communication in administrative meetings
Creators: name: Ferguson, Ian Andrew
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the study was to explicate some of the social-organizational features of administrative meetings through an examination of utterances and roles employed by participants during administrative meetings. In considerings some of the social-organizational features of administrative meetings, previous interaction analysis studies were reviewed and considered in terms of linguistic research. The core of the thesis was organizaed around the formulation that participants in administrative meetings shoulf be able to mobilize syntactic structures appropriate to a particular speech situation. This formulation was investigated by examining data from two separate administrative meetings, and considering some of the linguistic features of those conversations. It was found that chairmen perform chairmanship utterances differently depending on the social identity of the hearer. The clearest difference was in the performance of the speech function, "formulation". This was performed differently by the chairman of a meeting at which the other participants were all non-chairmen, from the way in which it was performed in the meeting where the hearer was not a multi-person. Confirming data, in the formaof other syntactic devices, were also considered. The findings from each meeting, A and B, were compared in terms of the findings from interaction analysis studies of meetings and the results noted. The chairman in meeting A was considered to be passive while the chairman in meeting B was considered to be active. The results and implications for further research are summarized in the final chapter.

description: O Manifesto dos Tupiboabas deglutiu e foi deglutido pelas tecnologias de comunicação e informação, e nesse processo construiu a performance cênica sobre a ética e a estética. De acordo com o conceito de virtual, (LEVY, 1996), a virtualização está entre as principais formas de criação de realidade, a qual está imersa na crise ambiental e de mudanças climáticas, ocasionadas por nocivos hábitos de consumo, produção industrial que utiliza materiais poluentes e adota métodos de inadequada exploração do trabalho. O Manifesto dos Tupiboabas, portanto, reuniu passado, presente e futuro na cena performática para evidenciar um olhar crítico sobre sociedade contemporânea, novas tecnologias e práticas globalizadoras. A metodologia de pesquisa conectou os estudos sobre o virtual às considerações presentes em O artífice (SENNETT, 2013). O resultado demonstrou a dialética necessária entre as tecnologias do espaço virtual e as tecnologias fabris no espaço material do meio ambiente e das relações humanas.

description: We show that the local Spike Timing-Dependent Plasticity (STDP) rule has the effect of regulating the trans-synaptic weights of loops of any length within a simulated network of neurons. We show that depending on STDP's polarity, functional loops are formed or eliminated in networks driven to normal spiking conditions by random, partially correlated inputs, where functional loops comprise weights that exceed a non-zero threshold. We further prove that STDP is a form of loop-regulating plasticity for the case of a linear network comprising random weights drawn from certain distributions. Thus a notable local synaptic learning rule makes a specific prediction about synapses in the brain in which standard STDP is present: that under normal spiking conditions, they should participate in predominantly feed-forward connections at all scales. Our model implies that any deviations from this prediction would require a substantial modification to the hypothesized role for standard STDP. Given its widespread occurrence in the brain, we predict that STDP could also regulate long range synaptic loops among individual neurons across all brain scales, up to, and including, the scale of global brain network topology.

description: Relying on the Hidden Local Symmetry (HLS) model equipped with a mechanism breaking the U(3)/SU(3)/SU(2) symmetries and generating a dynamical vector meson mixing, it has been shown that a global fit successfully describes the cross sections for the e+ e- -> pi+ pi-, e+ e- -> (pi0/eta) gamma and e+ e- -> pi0 pi+ pi- annihilation channels. One extends this global fit in order to include also the dipion spectra from the tau decay, taking into account all reported information on their statistical and systematic errors. A model accounting for lineshape distortions of the rho+- spectrum relative to rho0 is also examined when analyzing the tau data behavior within the global fit framework. One shows that a successful account for e+ e- annihilation data and tau spectra can be simultaneously reached. Then, issues related with non--perturbative hadronic contributions to the muon g-2 are examined in details. It is shown that all e+ e- data considered together allow for improved and motivated estimates for the a_mu(pi+ pi-), the pi+ pi- loop contribution to the muon g-2; for instance, integrated between 0.630 and 0.958 GeV, we find a_mu(pi+ pi-)= 359.62 +- 1.62 (in units of 10^{-10}), a 40% improvement of the current uncertainty. The effects of the various tau samples in the context of a global fit procedure leads to conclude that different lineshape distortions are revealed by the ALEPH, BELLE and CLEO data samples. Relying on global fits to the data quoted above, one also provides motivated estimates of the pi+ pi-, pi0 gamma, eta gamma and pi0 pi+ pi- contributions to a_mu up to 1 GeV with the smallest possible uncertainties. These estimates are based on various global fit configurations, each yielding a good probability.

On the curvature of dustlanes in galactic bars

description: We test the theoretical prediction that the straightest dust lanes in bars are found in strongly barred galaxies, or more specifically, that the degree of curvature of the dust lanes is inversely proportional to the strength of the bar. The test used archival images of barred galaxies for which a reliable non-axisymmetric torque parameter (Qb) and the radius at which Qb has been measured (r(Qb)) have been published in the literature. Our results confirm the theoretical prediction but show a large spread that cannot be accounted for by measurement errors. We simulate 238 galaxies with different bar and bulge parameters in order to investigate the origin of the spread in the dust lane curvature versus Qb relation. From these simulations, we conclude that the spread is greatly reduced when describing the bar strength as a linear combination of the bar parameters Qb and the quotient of the major and minor axis of the bar, a/b. Thus we conclude that the dust lane curvature is predominantly determined by the parameters of the bar.

description: Working together, DataCite and CDL have developed a set of Jupyter notebooks to demonstrate the power of networked, machine-actionable Data Management Plans (maDMPs) and to explore the potential connections of DMPs with other scholarly content (data, software, etc.) and with other PIDs (funder IDs, grant IDs, ORCIDs) via activities with the PID Graph.
 Utilizing open PIDs and PID services such as Event Data allow machine-actionable DMPs to connect all resources associated with a DMP such as contributors to a project, project outputs, data repositories, and funders. A healthy, open research infrastructure is key to enabling these connections and the open, declared connections between resources fuel the potential of machine-actionable DMPs to enable the tracking and updating of DMPs as research progresses over time.
Expressiveness of Concurrent Languages
Creators: name: Di Giusto, Cinzia <1979>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2009
Subjects: INF/01 Informatica

description: The aim of this thesis is to go through different approaches for proving expressiveness properties in several concurrent languages. We analyse four different calculi exploiting for each one a different technique.

We begin with the analysis of a synchronous language, we explore the expressiveness of a fragment of CCS! (a variant of Milner's CCS where replication is considered instead of recursion) w.r.t. the existence of faithful encodings (i.e. encodings that respect the behaviour of the encoded model without introducing unnecessary computations) of models of computability strictly less expressive than Turing Machines. Namely, grammars of types 1,2 and 3 in the Chomsky Hierarchy. 

We then move to  asynchronous languages and we study  full abstraction for two  Linda-like languages. Linda can be considered as the asynchronous version of CCS plus a shared memory (a multiset of elements) that is used for storing messages. After having defined a denotational semantics based on traces, we obtain fully abstract semantics for both languages by using suitable abstractions in order to identify different traces which do not correspond to different behaviours.

Since the ability of one of the two variants considered of recognising multiple occurrences of messages in the store (which accounts for an increase of expressiveness) reflects in a less complex abstraction, we then study other languages where multiplicity plays a fundamental role. We consider the language CHR (Constraint Handling Rules) a language which uses multi-headed (guarded) rules. We prove that multiple heads augment the expressive power of the language. Indeed  we  show that if we restrict to rules where the head contains at most n atoms we could generate a hierarchy of languages with increasing expressiveness (i.e. the CHR language allowing at most n atoms in the heads  is more expressive than the language allowing at most  m atoms, with m
Baryon Stopping in Heavy-Ion Collisions at E_{lab}= 2--160 GeV/nucleon

description: It is argued that the experimentally observed baryon stopping may indicate (within the present experimental uncertainties) a non-monotonous behaviour as a function of the incident energy of colliding nuclei. This can be quantified by a midrapidity reduced curvature of the net-proton rapidity spectrum. The above non-monotonous behaviour reveals itself as a "zig-zag" irregularity in the excitation function of this curvature. The three-fluid dynamic calculations with a hadronic equation of state (EoS) fail to reproduce this irregularity. At the same time, the same calculations with an EoS involving a first-order phase transition into the quark-gluon phase do reproduce this "zig-zag" behaviour, however only qualitatively.

Genomic characterization of the italian wolf (Canis lupus): 
 the genes involved in black coat colour determination 
and application of microarray technique for snps detection.

description: This study provides a comprehensive genetic overview on the endangered Italian wolf population.
In particular, it focuses on two research lines.
On one hand, we focalised on melanism in wolf in order to isolate a mutation related with black
coat colour in canids.
With several reported black individuals (an exception at European level), the Italian wolf population
constituted a challenging research field posing many unanswered questions. As found in North
American wolf, we reported that melanism in the Italian population is caused by a different
melanocortin pathway component, the K locus, in which a beta-defensin protein acts as an
alternative ligand for the Mc1r. This research project was conducted in collaboration with Prof.
Gregory Barsh, Department of Genetics and Paediatrics, Stanford University.
On the other hand, we performed analysis on a high number of SNPs thanks to a customized Canine
microarray useful to integrate or substitute the STR markers for genotyping individuals and
detecting wolf-dog hybrids. Thanks to DNA microchip technology, we obtained an impressive
amount of genetic data which provides a solid base for future functional genomic studies. This
study was undertaken in collaboration with Prof. Robert K. Wayne, Department of Ecology and
Evolutionary Biology, University of California, Los Angeles (UCLA).

description: Operadic Lax representations for the harmonic oscillator are used to construct the quantum counterparts of some 3d real Lie algebras in Bianchi classification. The Jacobians of these quantum algebras are studied. It is conjectured that the tangent algebras of these quantum algebras are the Heisenberg algebra. From this it follows that the volume element in $\mathbb{R}^{3}$ is quantized by $|(x,y,z)|=4\sqrt{2}(2n+1)$, ($n=0,1,2,\dots$). Thus, the elementary (minimal) length in this model is $l_{min}=2^{5/6}$.
