description: This paper examines the use of extension services by farm households across eight European Union (EU) Member States, exploring the type of extension service engaged with, the degree of engagement and the type of information sought. The impact of extension on economic, environmental and social sustainability is also considered. European data utilised are those collected from a pilot sample of 820 households in 2015/2016 as part of the EU Framework 7 project FLINT, from which the Irish results are incorporated further with Irish Farm Accountancy Data Network data. The results outline the key contrasts across the countries investigated and suggest that the degree to which households engage with extension services is primarily infl uenced by national policies. In addition, this analysis indicates that the extent of this engagement has implications for sustainability at the farm level. The final conclusions and policy recommendations in this paper support the development of a large-scale version of the FLINT pilot survey.

description: In the paradigm with a small warped Spacelike Extra Dimensions (SED), the Higgs field is in general localized at a boundary of the SED (TeV-brane) where the gravity scale is redshifted to the TeV by a warp factor. If the SM gauge bosons and fermions propagate into the warped SED, one can generate the mass hierarchy for fermions. It is thus crucial to treat carefully the TeV-brane localized masses for such fermions, which is done in the literature by applying a regularization process suffering from a lack of consistency and more importantly being useless, as we demonstrate in detail in the present thesis. The first part of the thesis is devoted to the treatment of brane localized mass terms for 5D fermions, which requires the introduction of new Lagrangian terms at the SED boundaries, similar to the Gibbons-Hawking terms in gravity. The second part consists in applying different methods (function/distribution fields, 4D/5D calculations, etc) to various brane localized terms (kinetic terms, Majorana masses, etc), as well as a generalization to several classified models (flat/warped dimensions, intervalle/orbifold, etc). In the third part, we propose to compactify a flat SED on a star/rose graph with a large number of identical small leaves/petals. We obtain a compactified space with a large volume without a large compactification length to stabilize. We use the approach of 5D fermions to build a toy model of small Dirac neutrino masses (brane localized left-handed neutrinos and bulk right-handed ones).

description: We present new observations of very faint white dwarfs (WDs) in the rich open star cluster NGC 2099 (M37). Following deep, wide field imaging of the cluster using CFHT, we have now obtained spectroscopic observations of candidate WDs using both GMOS on Gemini and LRIS on Keck. Of our 24 WD candidates (all fainter than V = 22.4), 21 are spectroscopically confirmed to be bona fide WDs, 4-5 of which are most likely field objects. Fitting 18 of the 21 WD spectra with model atmospheres, we find that most WDs in this cluster are quite massive (0.7-0.9 Msun), as expected given the cluster's young age (650 Myr) and, hence, high turnoff mass (~2.4 Msun). We determine a new initial-final mass relationship and almost double the number of existing data points from previous studies. The results indicate that stars with initial masses between 2.8 and 3.4 Msun lose 70-75% of their mass through stellar evolution. For the first time, we find some evidence of a metallicity dependence on the initial-final mass relationship.

description: Spectra have been obtained of 21 white dwarfs (WDs) in the direction of the young, rich open star cluster NGC 2099. This represents an appreciable fraction (>30%) of the cluster's total WD population. The mean derived mass of the sample is 0.8 Msun - about 0.2 Msun larger than the mean seen among field WDs. A surprising result is that all of the NGC 2099 WDs have hydrogen-rich atmospheres (DAs) and none exhibit helium-rich ones (DBs), or any other spectral class. The number ratio in the field at the temperatures of the NGC 2099 WDs is DA/DB ~ 3.5. While the probability of seeing no DB WDs in NGC 2099 solely by chance is ~2%, if we include WDs in other open clusters of similar age it then becomes highly unlikely that the dearth of DB WDs in young open clusters is just a statistical fluctuation. We explore possible reasons for the lack of DBs in these clusters and conclude that the most promising scenario for the DA/DB number ratio discrepancy in young clusters is that hot, high-mass WDs do not develop large enough helium convection zones to allow helium to be brought to the surface and turn a hydrogen-rich WD into a helium-rich one.

description: We analyze the amplitude of radiative charged pion photoproduction within the framework of heavy baryon chiral perturbation theory (HBChPT) and discuss the best experimental setup for the extraction of the charged pion polarizabilities from the differential cross section. We find that the contributions from two unknown low energy constants(LECs) in the $πN$ chiral Lagrangian at order $p^{3}$ are comparable with the contributions of the charged pion polarizabilities. As a result, it is necessary to take these two LECs' effects into account. Furthermore, we discuss the applicability of the extrapolation method and conclude that this method is applicable only if the polarization vector of the incoming photon is perpendicular to the scattering plane in the center of mass frame of the final $γ-π$ system.

description: We study classical dynamics of a probe Dp-brane moving in a background sourced by a stack of Dp-branes. In this context the physics is similar to that of the effective action for open-string tachyon condensation, but with a power-law runaway potential. We show that small inhomogeneous ripples of the probe brane embedding grow with time, leading to folding of the brane as it moves. We give a full nonlinear analytical treatment of inhomogeneous brane dynamics, suitable for the Dirac-Born-Infeld + Wess-Zumino theory with arbitrary runaway potential, in the case where the source branes are BPS. In the near-horizon geometry, the inhomogeneous brane motion has a dual description in terms of free streaming of massive relativistic test particles originating from the initial hypersurface of the probe brane. We discuss limitations of the effective action description around loci of self-crossing of the probe brane (caustics). We also discuss the effect of brane folding in application to the theory of cosmological fluctuations in string theory inflation.

description: We constructed an electrical circuit to realize a modified Haldane lattice exhibiting the unusual phenomenon of antichiral edge states. The circuit consists of a network of inductors and capacitors with interconnections reproducing the effects of a magnetic vector potential. The next nearest neighbor hoppings are configured differently from the standard Haldane model, and as predicted by earlier theoretical studies, this gives rise to antichiral edge states that propagate in the same direction on opposite edges and co-exist with bulk states at the same frequency. Using pickup coils to measure the voltage distributions in the circuit, we experimentally verify the key features of the modified Haldane lattice, including the group velocities of the antichiral edge states.

Aberrant hypermethylation of Xq12 in lymphoma
Creators: name: Quint, Désirée
Publisher: name: University of British Columbia
Year: 2010

description: It has been well established that abnormal CpG island promoter methylation in cancer is associated with the epigenetic silencing of tumour suppressor genes, genes that when inactivated predispose a cell to malignancy. Such aberrant methylation was seen for the androgen receptor (AR) located on the X chromosome in 84% of follicular lymphoma patient samples. Methylation has been shown to spread several megabases from its origin and this has led us to hypothesize that a candidate tumour suppressor gene is located in the vicinity ofthe AR. AR and the nearby oligophrenin (OPHNl) gene are both considered to be poor tumour suppressor gene candidates since deletions of these genes exist and they do not result in lymphoma. In addition, OPHNI is mainly expressed in brain tissues. In order to identify candidate genes, the extent of the abnormal CpG island methylation within the region surrounding the AR was first established in two different lymphoma cell lines (SUDHL3, DoHH2). A region of approximately 8 Mb was examined which led to the focus on a 1.5 Mb highly methylated sub-region located downstream of the AR. The methylation status of CpG islands within this sub- region was examined in three additional lymphoma cell lines (HBL-2, JVM-2 and 2138) as well as in patient samples. STARD8, a GTPase-activating protein, is located within this region and is abnormally silenced in at least two of the lymphoma cell lines making it a possible candidate.

description: Given the increased attention to risk management in the European Union’s (EU) Common Agricultural Policy (CAP), it is important to monitor and evaluate the rates of adoption by farmers and their determinants over time. Current European agricultural statistics (Farm Accountancy Data Network) capture few indicators that assess such strategies, but complementing data collected during the EU Framework 7 project FLINT have allowed the adoption of risk management strategies and the determinants of farmers’ preference for complementary or substitute instruments to be assessed. Adoption rates of risk management instruments such as insurance contracts, price contracts, off-farm income, other types risk of reduction measures and other gainful activities vary significantly across EU Member States and farming types. Econometric analysis indicates that larger farms more often adopt crop insurance, occupational accident insurance, price contracts and diversification but are less likely to adopt credit avoidance and off-farm employment (at a significance level of 1 per cent). For policy analyses these indicators are a step forward for the determination of the net impacts and establishment of counterfactuals in the long term (i.e. time series encompassing also adverse years) for measuring the impact of the CAP at farm level.

description: Spectral distortions of the cosmic microwave background (CMB) provide a unique tool for learning about the early phases of cosmic history, reaching deep into the primordial Universe. At redshifts $z<10^6$, thermalization processes become inefficient and existing limits from COBE/FIRAS imply that no more than $Δρ/ρ<6\times 10^{-5}$ (95% c.l.) of energy could have been injected into the CMB. However, at higher redshifts, when thermalization is efficient, the constraint weakens and $Δρ/ρ\simeq 0.01-0.1$ could in principle have occurred. Existing computations for the evolution of distortions commonly assume $Δρ/ρ\ll 1$ and thus become inaccurate in this case. Similarly, relativistic temperature corrections become relevant for large energy release, but have previously not been modeled as carefully. Here we study the evolution of distortions and the thermalization process after single large energy release at $z>10^5$. We show that for large distortions the thermalization efficiency is significantly reduced and that the distortion visibility is sizeable to much earlier times. This tightens spectral distortions constraints on low-mass primordial black holes with masses $M_{\rm PBH} < 6\times 10^{11}$ g. Similarly, distortion limits on the amplitude of the small-scale curvature power spectrum at wavenumbers $k>10^4\,{\rm Mpc}^{-1}$ and short-lived decaying particles with lifetimes $t_X< 10^7$ s are tightened, however, these still require a more detailed time-dependent treatment. We also briefly discuss the constraints from measurements of the effective number of relativistic degrees of freedom and light element abundances and how these complement spectral distortion limits.

Spin-Orbit Resonance and the Evolution of Compact Binary Systems

description: Starting with a post-Newtonian description of compact binary systems, we derive a set of equations that describes the evolution of the orbital angular momentum and both spin vectors during inspiral. We find regions of phase space that exhibit resonance behavior, characterized by small librations of the spin vectors around a fixed orientation. Due to the loss of energy and orbital angular momentum through radiation reaction, systems can eventually be captured into these resonance orientations. By investigating the long-term evolution of compact binaries with a variety of initial conditions, we find that the distribution in parameter space can be strongly affected by resonance captures. This has the effect of significantly reducing the size of search space for gravitational wave sources, in turn improving the chances of detecting such sources through methods of template matching. Furthermore, by calculating the expected spin distribution at the end of the inspiral phase, we can predict what are the most likely initial conditions for the plunge phase, a result of great interest for numerical relativity calculations.

description: In light of the ongoing efforts to build a new casino at the Vienna Prater, the urban function of a casino is being re-evaluated. The aim is to make a shift from often introverted architecture with no clear sense of location towards an architecture that connects to the urban context and its constantly changing functions and programs. It is these connections that make the casino and its immediate environment benefit from the vicinity to the Prater location, a location characterized by strong diversity, e.g. Vienna's Business University, Vienna Fair, "ViertelZwei", "Wurstel-Prater", Prater (nature), traffic junction Praterstern, Stuwerviertel ... A casino complements and provides 24-hour alternative use cases (especially in the evening and night hours) to the diverse and heterogeneous daily life between 9am and 5pm. Both of these "worlds" can benefit, if they are willing to engage with each other. Due to this new focus and orientation of the role of casinos, it becomes necessary to re-think and re-redevelop our historic concept of space, i.e. again shifting away from introverted, artificially illuminated lofts, towards space that seeks to connect to outside / natural daylight, not shying away from interacting and critically engaging with strange and foreign design elements.

description: When considering different hardware platforms, not just the time-to-solution can be of importance but also the energy necessary to reach it. This is not only the case with battery powered and mobile devices but also with high-performance parallel cluster systems due to financial and practical limits on power consumption and cooling. Recent developments in hard- and software have given programmers the ability to run the same code on a range of different devices giving rise to the concept of heterogeneous computing. Many of these devices are optimized for certain types of applications. To showcase the differences and give a basic outlook on the applicability of different architectures for specific problems, the cross-platform OpenCL framework was used to compare both time- and energy-to-solution. A large set of devices ranging from ARM processors to server CPUs and consumer and enterprise level GPUs has been used with different benchmarking testcases taken from applied research applications. While the results show the overall advantages of GPUs in terms of both runtime and energy efficiency compared to CPUs, ARM devices show potential for certain applications in massively parallel systems. This study also highlights how OpenCL enables the use of the same codebase on many different systems and hardware platforms without specific code adaptations.
A First Principle Study on Magneto-Optical Effects and Magnetism in Ferromagnetic Semiconductors Y$_3$Fe$_5$O$_{12}$ and Bi$_3$Fe$_5$O$_{12}$

description: The magneto-optical (MO) effects not only are a powerful probe of magnetism and electronic structure of magnetic solids but also have valuable applications in high-density data-storage technology. Yttrium iron garnet (Y$_3$Fe$_5$O$_{12}$) (YIG) and bismuth iron garnet (Bi$_3$Fe$_5$O$_{12}$) (BIG) are two widely used magnetic semiconductors with strong magneto-optical effects and have also attracted the attention for fundamental physics studies. In particular, YIG has been routinely used as a spin current injector. In this paper, we present a thorough theoretical investigation on magnetism, electronic, optical and MO properties of YIG and BIG, based on the density functional theory with the generalized gradient approximation plus onsite Coulomb repulsion. We find that both semiconductors exhibit large MO effects with their Kerr and Faraday rotation angles being comparable to that of best-known MO materials such as MnBi. Especially, the MO Kerr rotation angle for bulk BIG reaches -1.2$ ^{\circ}$ at photon energy $\sim2.4$ eV, and the MO Faraday rotation angle for BIG film reaches -74.6 $ ^{\circ}/μm$ at photon energy $\sim2.7$ eV. Furthermore, we also find that both valence and conduction bands across the MO band gap in BIG are purely spin-down states, i.e., BIG is a single spin semiconductor. These interesting findings suggest that the iron garnets will find valuable applications in semiconductor MO and spintronic nanodevices. The calculated optical conductivity spectra, MO Kerr and Faraday rotation angles agree well with the available experimental data. The main features in the optical and MO spectra of both systems are analyzed in terms of the calculated band structures especially by determining the band state symmetries and the main optical transitions at the $Γ$ point in the Brillouin zone.

Scotch broom (cytisus scoparius) and soil nitrogen : ecological implications
Creators: name: Shaben, Jacqueline
Publisher: name: University of British Columbia
Year: 2010

description: Scotch broom (Cytisus scoparius), a leguminous shrub with nitrogen-fixing rhizobial root associations, is an invasive plant in the endangered Garry oak ecosystem (GOE) of Southern British Columbia. Broom frequently spreads from disturbed areas such as power line right-of-ways, and thus is a threat to native ecosystems. To unravel the ecological relationship between Cytisus scoparius and soil nitrogen, I conducted two independent studies in 2004-2005. The first study assessed broom’s effect on nutrient availability and plant community composition in two Garry oak sites. The second evaluated the impact on seedling recruitment of broom following fertilization with biosolids obtained from sewage treatment. To determine if broom increased soil nitrogen availability, adjacent broom-invaded and non-invaded plots at two GOE sites (Rocky Point and Bamberton) were investigated. Here, soil-nutrient availability was compared using PRS[superscript TM] ion-exchange membrane probes and concurrent plant surveys. No differences were observed in nitrogen availability between broom-present and -absent plots except for a weak trend of higher Nl₄⁺ at Rocky Point. By contrast, phosphorus availability at Rocky Point was significantly lower in the broom-present plots. Plant richness was independent of broom presence, however multivariate analysis showed that species identity and abundance differed, with native species declining and introduced species increasing in the broominvaded plots. I conducted a complementary bioassay in which a native grass and an exotic grass were grown individually either with Cytisus or the native Holodiscus discolor, to test if grasses benefited from the presence of Cytisus. No difference in grass growth between treatment combinations was observed. The second study tested a novel method of broom control. With fertilization trials, I compared the efficacy of sewage biosolids and ammonium nitrate on the suppression of broom seedlings following broom removal. In addition, I conducted a greenhouse germination experiment to explore the mechanism of broom suppression. Broom seedlings were fewest and vegetation biomass tended to be highest in the biosolids plots. The germination experiment indicated no difference in broom germination rate when grown without plant competition. This suggests that the negative effects of biosolids on broom are due to increased competition from other plants for light and water. The management implications of these two studies are that Cytisus scoparius, though not correlated with dramatic increases in nitrogen availability, may alter phosphorus availability in GOE and thus influence plant composition. Addition of sewage biosolids to disturbed sites however, causes broom seedlings to lose their competitive advantage in dense vegetation that is facilitated by complete nutrient addition from biosolids.

description: We have studied the quasielastic 3He(e,e'p)d reaction in perpendicular coplanar kinematics, with the energy and momentum transferred by the electron fixed at 840 MeV and 1502 MeV/c, respectively. The 3He(e,e'p)d cross section was measured for missing momenta up to 1000 MeV/c, while the A_TL asymmetry was extracted for missing momenta up to 660 MeV/c. For missing momenta up to 150 MeV/c, the measured cross section is described well by calculations that use a variational ground-state wave function of the 3He nucleus derived from a potential that includes three-body forces. For missing momenta from 150 to 750 MeV/c, strong final-state interaction effects are observed. Near 1000 MeV/c, the experimental cross section is more than an order of magnitude larger than predicted by available theories. The A_TL asymmetry displays characteristic features of broken factorization, and is described reasonably well by available models.

description: The measurement of farm economic sustainability has received intermittent academic interest in recent times, while the conceptual discussions are often quite limited. Moreover, this concept receives more attention at periods of difficulty for the sector. The measurement of farm viability is an important precondition to enrich these discussions. Therefore, it is necessary to develop more comprehensive and detailed measurement techniques to provide more clarity on viability and vulnerability levels in the sector. This paper refocuses attention on this issue, using a pilot dataset collected at farm level across a range of EU Member States which facilitates the assessment of an additional category of viability, namely that of economically sustainable farms, i.e. farms that are economically vulnerable but which are deemed sustainable by the presence of off-farm income. Differences in viability and economic sustainability across the eight surveyed Member States are shown. The analysis is sensitive to the factors included in the measurement of viability as well as to the threshold income used to defi ne viability. Although this is a pilot study, it enhances our understanding of the factors affecting cross-country evaluation of viability and sustainability, and the policy instruments that could improve viability levels.

description: I use Unified Spinor Fields (USF), to discuss the creation of magnetic monopoles during preinflation, as excitations of the quantum vacuum coming from a condensate of massive charged vector bosons. For a primordial universe with total energy $M_p$, and for magnetic monopoles created with a total Planck magnetic charge $q_M=q_P=\pm e/\sqrtα$ and a total mass $m_M$, it is obtained after quantisation of the action that the fine-structure constant is given by: $α= \frac{5}{6} \left(1- \frac{16 \,m_M}{5 \,M_p}\right) \,\left(\frac{e}{q_M}\right)^2$. If these magnetic monopoles were with total magnetic charge $q_M=\pm e$ and a small mass $m=m_M/n$, there would be a large number of small quantum magnetic monopoles which could be candidates to explain the presence of dark matter with a $30.97\,\%$ of the energy in the primordial universe at the Planck era. The case of milli-magnetically charged particles is also analysed. We demonstrate that magnetic monopoles (MM) with masses less than $3.6\times 10^3$ GeV, can exist with a very small charges of up to $10^{-14}\,e$, which are quantities of interest for searches to be performed in the ATLAS and MoEDAL experiments.

description: At present, the anticarcinogenic properties of nine heterocyclic thiosemicarbazone copper(II) complexes of the type [Cu(L1 − 3)2] (1–3), [Cu(L1 − 3)(bpy)]Cl (4–6), and [Cu(L1 − 3)(phen)]Cl (7–9) have been synthesized from three sulfur containing ligands such as (E)-2-(2-(benzo[d]thiazol-2-ylthio)-1-phenylethylidene)-N-methylhydrazinecarbothioamide H(L1), (E)-2-(2-(benzo[d]thiazol-2-ylthio)-1-phenylethylidene)-N-ethylhydrazinecarbothio amide H(L2) and (E)-2-(2-(benzo[d]thiazol-2-ylthio)-1-phenylethylidene)-N-phenylhydrazinecarbothioamide H(L3) with diimine co-ligands (bpy = 2,2′-bipyridyl, phen = 1,10-phenanthroline). The synthesized ligands were characterized by FT-IR, UV-vis, 1H and 13C NMR spectroscopies. All the complexes were characterized using various spectro-analytical techniques such as molar conductivity, elemental analysis and UV-vis, FT − IR and EPR spectroscopy. Also, it confirms the square planar coordination of the mixed-ligand copper(II) complexes by one deprotonated ligand and N,N′-donor of bidentate ligand while in copper(II) bis complexes coordinated by two deprotonated ligands. In addition, biological functions of the synthesized compounds have been investigated using the disc diffusion method, agarose gel electrophoresis and MTT assay. Fascinatingly, complexes with heteroaromatic moieties had potential biological activities rather than copper(II) bis complexes. This relative increase in the biological effects of copper(II) complexes is possibly due to the presence of different substituents at thioamide and phen moiety. From this study, it was concluded that the mixed-ligand copper(II) complexes could be considered as an effective chemotherapeutic drug.

description: Innovation and adoption of innovation are considered key indicators of competitiveness and sustainability. Analysing data from 821 farms from eight Member States of the European Union in the frame of the EU Framework 7 project FLINT, this study provides an insight into the different adoption rates of fi ve types of innovation in agriculture across Europe and suggests the potential effects of different factors, including farm type and farm size, subsidies and age, on farmers’ decision to innovate.

description: Iran is endowed with excellent climatic and tectonic conditions for harvesting green energy. The main objectives of this thesis were to identify the technical potential and the economic feasibility of three specific renewable energy sources, namely solar/photovoltaic, wind and geothermal energy. In addition, this study looked at current energy-policies and how they support or hinder the development of sustainable energy. The strengths, weaknesses, opportunities and threats were aggregated, giving an overview of the country's to-do list for a successful green energy future in particular under the perspective of UN-sanctions relief in January of 2016. While the technical potential was estimated with mathematical equations based on available data, statistics (e.g. Weibull distribution) and assumptions, the economic potential (NPV, LRGC, project/equity IRR) was calculated for one specific site or plant per energy source under real-time conditions (feed-in-tariffs, escalation rate, inflation exchange, etc.), including a stress test (sensitivity analyses) for O & M costs, feed-in-tariffs and full-load-hours. The research was rounded up with a two month cooperation stay on-site with the Research Institute of Energy Management and Planning (RIEMP). The examination of current energy-policies was conducted with a SWOT analysis, followed by recommendations and strategies for policy-makers and investors. The technical potential for solar energy was estimated to be 56,597 GWp, 186,102 GWh for wind, and 35,723 MWe for geothermal. Under current energy policies, solar power plants are considerable while wind and geothermal power plants are highly economically viable. SWOT analysis of Iran's 2021 target of 5,000 MW renewables installed capacity concluded that the country will need to make a comprehensive long-term renewable energy package, tackle environmentally harmful subsidies, maintain highly competitive long-run guaranteed purchase prices and additional incentives on renewable energy sources, empower banks and civil society, invest in education and strive for international technology and know-how transfer.

description: Recent studies have found the earth's peculiar velocity to be significant in microwave background based tests for compact cosmic topology, and modifications to these tests have been proposed. Tests of non-gaussianity, weak lensing analysis and new tests using improved CMB data will also be sensitive to peculiar velocity. We propose here to simplify matters by showing how to construct a deaberrated CMB map to which any test requiring a Hubble flow viewpoint can be applied without further complication. In a similar manner deaberration can also be applied to object surveys used for example in topological searches and matter distribution analysis. In particular we have produced a revised list of objects with z > 1.0 using the NASA/IPAC Extragalactic Database.

description: We study the mutual information between two lattice-blocks in terms of von Neumann entropies for one-dimensional infinite lattice systems. Quantum $q$-state Potts model and transverse field spin-$1/2$ XY model are considered numerically by using the infinite matrix product state (iMPS) approach. As a system parameter varies, block-block mutual informations exhibit a singular behavior that enables to identify critical points for quantum phase transition. As happens with the von Neumann entanglement entropy of a single block, at the critical points, the block-block mutual information between the two lattice-blocks of $\ell$ contiguous sites equally partitioned in a lattice-block of $2\ell$ contiguous sites shows a logarithmic leading behavior, which yields the central charge $c$ of the underlying conformal field theory. As the separation between the two lattice-blocks increases, the mutual information reveals a consistent power-law decaying behavior for various truncation dimensions and lattice-block sizes. The critical exponent of block-block mutual information in the thermodynamic limit is estimated by extrapolating the exponents of power-law decaying regions for finite truncation dimensions. For a given lattice-block size $\ell$, the critical exponents for the same universality classes seem to have very close values each other. Whereas the critical exponents have different values to a degree of distinction for different universality classes. As the lattice-block size becomes bigger, the critical exponent becomes smaller.
