description: We study a model of communication complexity that encompasses many well-studied problems, including classical and quantum communication complexity, the complexity of simulating distributions arising from bipartite measurements of shared quantum states, and XOR games. In this model, Alice gets an input x, Bob gets an input y, and their goal is to each produce an output a,b distributed according to some pre-specified joint distribution p(a,b|x,y). We introduce a new technique based on affine combinations of lower-complexity distributions. Specifically, we introduce two complexity measures, one which gives lower bounds on classical communication, and one for quantum communication. These measures can be expressed as convex optimization problems. We show that the dual formulations have a striking interpretation, since they coincide with maximum violations of Bell and Tsirelson inequalities. The dual expressions are closely related to the winning probability of XOR games. These lower bounds subsume many known communication complexity lower bound methods, most notably the recent lower bounds of Linial and Shraibman for the special case of Boolean functions. We show that the gap between the quantum and classical lower bounds is at most linear in the size of the support of the distribution, and does not depend on the size of the inputs. This translates into a bound on the gap between maximal Bell and Tsirelson inequality violations, which was previously known only for the case of distributions with Boolean outcomes and uniform marginals. Finally, we give an exponential upper bound on quantum and classical communication complexity in the simultaneous messages model, for any non-signaling distribution. One consequence is a simple proof that any quantum distribution can be approximated with a constant number of bits of communication.

description: Both single-laser and two-laser experiments were conducted to look into the ion-imaging of Br*(2P1/2) and Br(2P3/2) photo-fragmented from 1-bromo-2-methylbutane in the range 232-240 nm via a detection scheme of (2+1) resonance-enhanced multiphoton ionization. The angular analysis of these photofragment distributions yields the anisotropy parameter beta = 1.88 +/- 0.06 for the Br* excited state which arises from a parallel transition, while beta = 0.63 +/- 0.09 for the Br ground state indicates the contribution from both a perpendicular transition and a non-adiabatic transition. When a hexapole coupled with an orienting field was implemented, the parent molecules are spatially oriented to yield an orientation efficiency || of 0.15. Besides the chi angle between the recoil velocity v and the transition dipole moment mu, orienting molecules allows for the evaluation of the angle alpha between v and the permanent molecular dipole moment d. The angular analysis of Br* photofragment distribution yields chi to be 11.5 degrees and alpha in the range from 160 degrees to 180 degrees with weak dependency. In the two-laser experiments, the angular anisotropy of Br photofragment distribution was found to be smaller (0.38 +/- 0.10) when the photolysis wavelength was red-shifted to 240 nm, suggesting the increasing contributions from perpendicular transitions.

description: We study the conversion of $^{40}$K and $^{87}$Rb atoms into stable molecules through the stimulated Raman adiabatic passage (STIRAP) in photoassociation assisted with Feshbach resonance. Starting with the mean-field Langrange density, we show that the atom-to-molecule conversion efficiency by STIRAP aided by Feshbach resonance is much larger than that by bare Feshbach resonance. We also study the influence of the population imbalance on the atom-to-molecule conversion.

Localization of quantum wave packets

Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We study the semiclassical propagation of squeezed Gaußian states. We do so by considering the propagation theorem introduced by Combescure and Robert \cite{CR97} approximating the evolution generated by the Weyl-quantization of symbols $H$. We examine the particular case when the Hessian $H^{\prime\prime}(X_{t})$ evaluated at the corresponding solution $X_{t}$ of Hamilton's equations of motion is periodic in time. Under this assumption, we show that the width of the wave packet can remain small up to the Ehrenfest time. We also determine conditions for ``classical revivals'' in that case. More generally, we may define recurrences of the initial width. Some of these results include the case of unbounded classical motion. In the classically unstable case we recover an exponential spreading of the wave packet as in \cite{CR97}.

description: We simulate a trapped quasi-two-dimensional Bose gas using a classical field method. To interpret our results we identify the uniform Berezinskii-Kosterlitz-Thouless (BKT) temperature $T_{BKT}$ as where the system phase space density satisfies a critical value. We observe that density fluctuations are suppressed in the system well above $T_{BKT}$ when a quasi-condensate forms as the first occurrence of degeneracy. At lower temperatures, but still above $T_{BKT}$, we observe the development of appreciable coherence as a prominent finite-size effect, which manifests as bimodality in the momentum distribution of the system. At $T_{BKT}$ algebraic decay of off-diagonal correlations occurs near the trap center with an exponent of 0.25, as expected for the uniform system. Our results characterize the low temperature phase diagram for a trapped quasi-2D Bose gas and are consistent with observations made in recent experiments.

description: Spin-orbit interactions (SOIs) endow light with intriguing properties and applications such as photonic spin-Hall effects and spin-dependent vortex generations. However, it is counterintuitive that SOIs can exist for sound, which is a longitudinal wave that carries no intrinsic spin. Here, we theoretically and experimentally demonstrate that airborne sound can possess artificial transversality in an acoustic micropolar metamaterial and thus carry both spin and orbital angular momentum. This enables the realization of acoustic SOIs with rich phenomena beyond those in conventional acoustic systems. We demonstrate that acoustic activity of the metamaterial can induce coupling between the spin and linear crystal momentum k, which leads to negative refraction of the transverse sound. In addition, we show that the scattering of the transverse sound by a dipole particle can generate spin-dependent acoustic vortices via the geometric phase effect. The acoustic SOIs can provide new perspectives and functionalities for sound manipulations beyond the conventional scalar degree of freedom and may open an avenue to the development of spin-orbit acoustics.

description: The $Λ^{\ast}$-hypernuclei, which are bound states of $Λ(1405)$ and nuclei, are discussed as a possible interpretation of the $\bar{K}$-nuclei. The Bonn and Nijmegen potentials are extended and used as a phenomenological potential between $Λ^{\ast}$ and $N$. The $K$-exchange potential is also considered in the $Λ^{\ast}$ and $N$ interaction. The two-body ($Λ^{\ast}N$) and three-body ($Λ^{\ast}NN$) systems are solved by a variational method. It is shown that the spin and isospin of the ground states are assigned as $Λ^{\ast}N(S=1, I=1/2)$ and $Λ^{\ast}NN(S=3/2, I=0)$, respectively. The binding energies of the $Λ^{\ast}$-hypernuclei are discussed in comparison with experiment.

Te Mana Motuhake Me Te Iwi Maori : indigineous self determination
Creators: name: Williams, Joseph Victor
Publisher: name: University of British Columbia
Year: 2010

description: Maria Maori Motuhake or Maori self determination is developing into one of the most pressing political and legal issues in modern New Zealand. The Maori struggle for recognition of that right is a long one. It began with contact with British colonisers, and has continued in different forms throughout New Zealand's history. The following thesis suggests that that struggle is one which the Maori share with Indigenous peoples throughout the world. The recognition in law of Mana Maori Motuhake in New Zealand will come from an understanding, by both Maori and Pakeha, of the international nature of that struggle. Accordingly the essential purpose of this thesis is to put the issue of Maori rights into an international and colonial perspective. In Part I, the question of Indigenous self determination is discussed in the context of historical and contemporary developments in international law. It is concluded firstly that there is room for the proposition that a right of Indigenous self determination can be drawn from the current state of international law. Secondly, it is argued that recent developments in the United Nations suggest positive recognition of that right will occur in the near future. In Part II, the development of colonial law in the United States, Canada and New Zealand add a further dimension to this international perspective. In this part parallel developments in the three countries are highlighted to prove the 'indivisibility' of colonialism, and the inexorable development in modern law toward recognition of the 'colonial paradigm'- Native title and Native sovereignty.

title: Meat and social change: Sociological perspectives on the consumption and production of animals
Creators: name: Nungesser, Frithjof
name: Winter, Martin
Publisher: name: VS Verlag für Sozialwissenschaften
Year: 2024

description: Meat is a crucial object of sociological research. The consumption of meat plays a significant role in the food supply of modern societies. The importance of meat is not, however, limited to its nutritional value. Rather, the preparation and consumption of meat dishes is linked to cultural traditions and norms, collective and individual identities, as well as to gender relations and conceptions of health, purity, or naturalness. The production of meat is connected to numerous ecological problems, the breeding and killing of billions of animals, precarious working conditions and issues of public health (as, for example, the current pandemic demonstrates). Moreover, both the consumption and production of meat are linked to various dynamics of transformation and conflict: Technical and scientific innovations as well as political and economic decisions transform agriculture and meat production, leading to an unparalleled productivity but also to unprecedented environmental consequences. While the "normality" of meat consumption spreads further around the globe and is no longer exclusive to the Global North, in Western societies problems related to meat increasingly become the subject of public debates and social struggles.

description: Il lavoro si concentra sull’analisi delle principali proprietà dei processi Polya Tree e sull’individuazione dei contesti inferenziali in cui è vantaggioso l’utilizzo di tali processi L’utilizzo dei processi Polya Tree è infatti appropriato in molteplici contesti inferenziali, in particolare l’analisi della sopravvivenza e della distribuzione dei redditi in presenza di dati censurati. L’elevato numero di parametri caratterizzanti un processo Polya Tree permette di modulare la forma della distribuzione a priori oggetto di stima per ogni intervallo di nostro interesse in base alle specifiche conoscenze a priori. Tramite un’opportuna scelta dei parametri i processi Polya Tree derivano distribuzioni continue. Tale proprietà consente la facile simulazione di un campione dalla distribuzione a posteriori derivata.

description: We investigate the usefulness of a recently introduced five qubit state by Brown $\it et al. \normalfont$ \cite{Brown} for quantum teleportation, quantum state sharing and superdense coding. It is shown that this five-qubit state can be utilized for perfect teleportation of arbitrary single and two qubit systems. We devise various schemes for quantum state sharing of an arbitrary single and two particle state via cooperative teleportation. We later show that this state can be used for superdense coding as well. It is found that five classical bits can be sent by sending only three quantum bits.

description: In this paper we study relative Riemann-Zariski spaces attached to a morphism of schemes and generalizing the classical Riemann-Zariski space of a field. We prove that similarly to the classical RZ spaces, the relative ones can be described either as projective limits of schemes in the category of locally ringed spaces or as certain spaces of valuations. We apply these spaces to prove the following two new results: a strong version of stable modification theorem for relative curves; a decomposition theorem which asserts that any separated morphism between quasi-compact and quasi-separated schemes factors as a composition of an affine morphism and a proper morphism. (In particular, we obtain a new proof of Nagata's compactification theorem.)

description: The forthcoming Planck experiment will provide high sensitivity polarization measurements that will allow us to further tighten the f_NL bounds from the temperature data. Monte Carlo simulations of non-Gaussian CMB maps have been used as a fundamental tool to characterize non-Gaussian signatures in the data, as they allow us to calibrate any statistical estimators and understand the effect of systematics, foregrounds and other contaminants. We describe an algorithm to generate high-angular resolution simulations of non-Gaussian CMB maps in temperature and polarization. We consider non-Gaussianities of the local type, for which the level of non-Gaussianity is defined by the dimensionless parameter, f_NL. We then apply the temperature and polarization fast cubic statistics recently developed by Yadav et al. to a set of non-Gaussian temperature and polarization simulations. We compare our results to theoretical expectations based on a Fisher matrix analysis, test the unbiasedness of the estimator, and study the dependence of the error bars on f_NL. All our results are in very good agreement with theoretical predictions, thus confirming the reliability of both the simulation algorithm and the fast cubic temperature and polarization estimator.

Investigating Perceptions of Social Intelligence in Simulated Human-Chatbot Interactions

Year: 2021
Subjects: subject: Human-Computer Interaction (cs.HC)

description: With the ongoing penetration of conversational user interfaces, a better understanding of social and emotional characteristic inherent to dialogue is required. Chatbots in particular face the challenge of conveying human-like behaviour while being restricted to one channel of interaction, i.e., text. The goal of the presented work is thus to investigate whether characteristics of social intelligence embedded in human-chatbot interactions are perceivable by human interlocutors and if yes, whether such influences the experienced interaction quality. Focusing on the social intelligence dimensions Authenticity, Clarity and Empathy, we first used a questionnaire survey evaluating the level of perception in text utterances, and then conducted a Wizard of Oz study to investigate the effects of these utterances in a more interactive setting. Results show that people have great difficulties perceiving elements of social intelligence in text. While on the one hand they find anthropomorphic behaviour pleasant and positive for the naturalness of a dialogue, they may also perceive it as frightening and unsuitable when expressed by an artificial agent in the wrong way or at the wrong time.

The development of ocean incineration law in Canada
Creators: name: Hughes, Elaine Lois
Publisher: name: University of British Columbia
Year: 2010

description: The present study is designed to examine the structure and development of international and Canadian laws which attempt to regulate the ocean disposal of toxic waste by at-sea incineration. It begins by describing some of the hazardous wastes which are creating dangerous environmental problems in Canada and other nations, by introducing the reader to the types of toxic materials subject to incineration and dumping at sea, and to the nature of the hazards these materials create. With this background in mind, the historical development of ocean dumping laws is then described, beginning with the major international treaties that presently regulate dumping activities. The Canadian laws, which emerged in order to implement the international treaty obligations, are then examined, together with an outline of how these laws are actually administered in the Canadian constitutional and political context. Emerging political strategies to improve the management and disposal of toxic waste are examined, including the increased use of incineration technology. The actual use and legal regulation of ocean incineration is then described, in an attempt to determine whether this type of ocean disposal is a useful and controllable waste management option. Current Canadian policy and legal proposals on ocean incineration are examined in light of ongoing international controversy over the advisability of its use as a waste management strategy. The study examines several jurisdictional, economic, scientific, and political problems which, in the Canadian context, cast doubt upon the ability of government to obtain either public acceptance of ocean incineration, or adequate legal control over at-sea incineration operations. In particular, the relevant legal, political and administrative decision-making processes are reviewed, to identify areas in which improvements are needed. It is concluded that government should move away from incremental law and policy formation, and start to experiment with new forms of decision-making processes, in order to deal with such complex and difficult issues. It is recommended that the government seek to respond in new and innovative ways to these problems. Resolving the question of the desirability of ocean incineration is seen as a possible "pilot project" to test the ability of Canadian legal and political institutions to meet the future challenges posed by such environmental issues. The policies and legislation discussed in the study are reported as of June 30, 1988.

We then apply this to the theory of weak omega-categories, showing that the universal and canonical cofibrant replacement of the operad for strict omega-categories is precisely Leinster's operad for weak omega-categories.

description: Conformal Weyl and Cotton tensors are dimensionally reduced by a Kaluza-Klein procedure. Explicit formulas are given for reducing from four and three dimensions to three and two dimensions, respectively. When the higher dimensional conformal tensor vanishes because the space is conformallly flat, the lower-dimensional Kaluza-Klein functions satisfy equations that coincide with the Einstein-Weyl equations in three dimensions and kink equations in two dimensions.

description: The origin of magnetic fields in astrophysical objects is a challenging problem in astrophysics. Throughout the years, many scientists have suggested that non-minimal gravitational-electromagnetic coupling (NMGEC) could be the origin of the ubiquitous astrophysical magnetic fields. We investigate the possible origin of intense magnetic fields $\sim 10^{15}-10^{16}$ by NMGEC near rotating neutron stars and black holes, connected with magnetars, quasars, and gamma-ray bursts. Whereas these intense magnetic fields are difficult to explain astrophysically, we find that they are easily explained by NMGEC.

description: We present a detailed analysis of the neutron, deuteron and mercury electric dipole moment from supersymmetry without R parity, focusing on the quark-scalar loop contributions. Being proportional to top Yukawa and top mass, such contributions are often large. Analytical expressions illustrating the explicit role of the R-parity violating parameters are given following perturbative diagonalization of mass-squared matrices for the scalars. Dominant contributions come from the combinations $B_i λ^{\prime}_{ij1}$ for which we obtain robust bounds. It turns out that neutron and deuteron EDMs receive much stronger contributions than mercury EDM and any null result at the future deuteron EDM experiment or Los Alamos neutron EDM experiment can lead to extra-ordinary constraints on RPV parameter space. Even if R-parity violating couplings are real, CKM phase does induce RPV contribution and for some cases such a contribution is as strong as contribution from phases in the R-parity violating couplings.Hence, we have bounds directly on $|B_i λ^{\prime}_{ij1}|$ even if the RPV parameters are all real. Interestingly, even if slepton mass and/or $μ_0$ is as high as 1 TeV, it still leads to neutron EDM that is an order of magnitude larger than the sensitivity at Los Alamos experiment. Since the results are not much sensitive to $\tan β$, our constraints will survive even if other observables tighten the constraints on $\tan β$.

description: The ²³Na(α, p)²⁶Mg reaction has been identified as having a significant impact on the nucleosynthesis of several nuclei between Ne and Ti in Type Ia supernovae, and of ²³Na and ²⁶Al in massive stars. The reaction has been subjected to renewed experimental interest recently, motivated by high uncertainties in early experimental data and in the statistical Hauser-Feshbach models used in reaction rate compilations. Early experiments were affected by target deterioration issues and unquantifiable uncertainties. Three new independent measurements instead are utilizing inverse kinematics and Rutherford scattering monitoring to resolve this. In this work we present directly measured angular distributions of the emitted protons to eliminate a discrepancy in the assumptions made in the recent reaction rate measurements, which results in cross sections differing by a factor of 3. We derive a new combined experimental reaction rate for the ²³Na(α, p)²⁶Mg reaction with a total uncertainty of 30% at relevant temperatures. Using our new ²³Na(α, p)²⁶Mg rate, the ²⁶Al and ²³Na production uncertainty is reduced to within 8%. In comparison, using the factor of 10 uncertainty previously recommended by the rate compilation STARLIB, ²⁶Al and ²³Na production was changing by more than a factor of 2. In Type Ia supernova conditions, the impact on production of ²³Na is constrained to within 15%.
Environmental protection of the circumpolar arctic waters : A comparative study and an appraisal of the National Regulatory Systems
Creators: name: Harders, Johannes Enno
Publisher: name: University of British Columbia
Year: 2010

description: Canada, the United States-Alaska, the Soviet Union-RSFSR, Norway, and Denmark/Greenland have non-specific laws apply for the environmental protection of their Arctic lands, waters, and marine spaces. But the piecemeal approaches employed neglect the need for environmentally sound management in respect of the multiple uses of the polar sea's delicate ecosystems. Convenient component elements of Arctic pollution are chosen for examination -- (1) land-based sources of freshwater pollution and (2) marine-borne pollution resulting from offshore drilling and Arctic shipping. This comparative study moreover serves three objectives: (1) the exposition of the statutory instruments and administrative materials; (2) the evaluation of the national approaches taken for environmental protection generally and Arctic protection specifically; and (3) the appraisal of the accommodation and resolution of conflicts over interests concerning economic uses vis-a-vis environmental protection. In the chapter on each state a background makes reference to the national socio-legal and international legal conditions affecting municipal Arctic pollution control. The next section on the national regulatory framework follows the territorial and jurisdictional zones of the coastal state: from land-based operations affecting the freshwaters, to the coastal area, the body of law on shipping and navigation, the environmental provisions of a 200 nautical mile exclusive economic zone, the continental shelf activities, to the regime on deep sea-bed mining. The latter of which ends this section and provides for the evaluation given in the concluding section on the country in question. The states have taken different avenues in their pollution control enactments: (1) blanket prohibition or the regulation of pollution; (2) the enforcement and supervision of statutory provisions; and/or (3) civil and criminal liability for violations of respective measures. Every state provides precedences for a number of recommendations in order to facilitate resource uses, environmental protection, and the integration of the Arctic natives in an ecosystem management approach to environmental protection. Examples are such like Norway's integrated statute on pollution prevention, the United States' legislation on coastal zone management and environmental impact assessments, and Canada's framework on Arctic shipping and Arctic pollution prevention.

description: In the LHC searches for gluinos it is usually assumed that they decay predominantly into the lightest neutralino plus jets. In this work we perform a proof-of-concept collider analysis of a novel supersymmetric signal in which gluinos decay mostly into jets and the bino-like neutralino ($\tildeχ_3^0$), which in turn decays into the lightest Higgsino-like neutralino ($\tildeχ_1^0$), considered the dark matter candidate, together with the SM-like Higgs boson ($h$). This new physics signal then consists of an LHC final state made up by four light jets, four $b$-jets, and a large amount of missing transverse energy. We identify $t \bar t$, $V$+jets ($V$= $W$, $Z$), and $t \bar t + X$ ($X$ = $W$, $Z$, $γ^*$, $h$) productions as the most problematic backgrounds, and develop a search strategy for the high luminosity phase of the LHC, reaching signal significances at the evidence level for a luminosity of 1000 fb$^{-1}$. The prospects for a luminosity of 3000 fb$^{-1}$ are even more promising, with discovery-level significances.

description: We present a scheme for robust and efficient projection measurement of a qubit consisting of the two magnetic sublevels in the electronic ground state of alkali earth metal ions. The scheme is based on two stimulated Raman adiabatic passages (STIRAP) involving four partially coherent laser fields. We show how the efficiency depends on experimentally relevant parameters: Rabi frequencies, pulse widths, laser linewidths, one- and two-photon detunings, residual laser power, laser polarization and ion motion.

description: Hardly any software development process is used as prescribed by authors or standards. Regardless of company size or industry sector, a majority of project teams and companies use hybrid development methods (short: hybrid methods) that combine different development methods and practices. Even though such hybrid methods are highly individualized, a common understanding of how to systematically construct synergetic practices is missing. In this article, we make a first step towards a statistical construction procedure for hybrid methods. Grounded in 1467 data points from a large-scale practitioner survey, we study the question: What are hybrid methods made of and how can they be systematically constructed? Our findings show that only eight methods and few practices build the core of modern software development. Using an 85% agreement level in the participants' selections, we provide examples illustrating how hybrid methods can be characterized by the practices they are made of. Furthermore, using this characterization, we develop an initial construction procedure, which allows for defining a method frame and enriching it incrementally to devise a hybrid method using ranked sets of practice.

title: Impact of a Magnetic Field on Neutrino–Matter Interactions in Core-collapse Supernovae
Creators: name: Kuroda, Takami
Publisher: name: The American Astronomical Society
Year: 2024

description: We explore the impact of a magnetic field on neutrino–matter interactions in core-collapse supernovae. We first derive the modified source terms for neutrino–nucleon scattering and neutrino absorption and emission processes in the moment formalism. Then, we perform full relativistic, three-dimensional, magnetorotational core-collapse supernova simulations of a star with spectral neutrino transport. Our simulations self-consistently treat the parity-violation effects of weak interaction in the presence of an external magnetic field. The result shows significant global asymmetry, mostly confined in the proto-neutron star, clearly reflecting the magnetic field structure. The asymmetric property arises from two factors: the angle between the neutrino flux and magnetic field, and the term that is parallel to the magnetic field and is also proportional to the deviation of the distribution function of neutrinos from thermal equilibrium. The typical correction value amounts to ∼1% relative to the total neutrino–matter interaction rate for the magnetic field strength of G. Although these asymmetric properties do not immediately affect the explosion dynamics, our results imply that they would be significant once the neutrinos diffuse out of the proto-neutron- star core carrying those asymmetries away. We also show that, during our simulation time of ∼370 ms after bounce, our results indicate that the correction value due to the modified inelastic scattering process dominates over that of the modified neutrino absorption and emission process.

description: We investigate one-dimensional Josephson junction arrays with generalized unit cells as a circuit approach to engineer microwave band gaps. An array described by a lattice with a basis can be designed to have a gap in the electromagnetic spectrum, in full analogy to electronic band gaps in diatomic or many-atomic crystals. We derive the dependence of this gap on the array parameters in the linear regime, and suggest experimentally feasible designs to bring the gap below the single junction plasma frequency. The gap can be tuned in a wide frequency range by applying external flux, and it persists in the presence of small imperfections.

description: No abstracts are to be cited without prior reference to the author.Cod of the Norwegian and Murmansk coastal areas is a part of a uniform superpopulation whose range is within the entire Norwegian - Barents Sea region. The size of the inshore part of the stock results from the actual distribution offish, specific for given year, which is dependent not only on the hydrological and feeding conditions but also on population abundance. A part of the population which got into the inshore zone including inlets, bays and f)Ords remains there for a long period of time, and acquires some features during several years which make it different from the representatives of cod that used to stay on the high seas. Nevertheless, there are no natural obstacles for contacts between these temporary ecological groupings including contacts during spawning. The uninterrupted exchange of migrants between the high seas and the inshore regions shows that the existing practice of allocating special quotas for inshore cod is biologically unfounded. The size of TAG should be established accordingly, as based on the total fishing stock of cod throughout its range. Given the present intensive development of inshore fisheries the applied aspect of the problem becomes increasingly currently central. Being against a priori presumptuous judgements the authors have attempted, to the extent possible, to consider objectively and in a comprehensive way all the arguments available in favour and against the existence of isolated populations. For the sake of analysis all the published material available to us was grouped according to the characteristics used as potential markers allowing us to attribute cod to a particular population.
