Evolutionary foundations of cooperation and group cohesion

description: In biology, the evolution of increasingly cooperative groups has shaped the history of life. Genes collaborate in the control of cells; cells efficiently divide tasks to produce cohesive multicellular individuals; individual members of insect colonies cooperate in integrated societies. Biological cooperation provides a foundation on which to understand human behavior. Conceptually, the economics of efficient allocation and the game-like processes of strategy are well understood in biology; we find the same essential processes in many successful theories of human sociality. Historically, the trace of biological evolution informs in two ways. First, the evolutionary transformations in biological cooperation provide insight into how economic and strategic processes play out over time--a source of analogy that, when applied thoughtfully, aids analysis of human sociality. Second, humans arose from biological history--a factual account of the past that tells us much about the material basis of human behavior.

description: Este ensayo traza un recorrido histórico, filosófico y tecnológico para argumentar que la humanidad se encuentra ante una mutación cognitiva sin precedentes: el surgimiento del Pensamiento Aumentado. En sus primeros tramos, la obra describe la lenta evolución del conocimiento humano, desde la transmisión oral hasta los manuscritos medievales, destacando el sacrificio vital de los escribas como símbolo de la lucha contra el olvido. A partir del desarrollo del lenguaje y la emergencia de la ciencia como aliada de la filosofía, se configura una cuadratura virtuosa que será fracturada cuando el capital deja de ser medio y se convierte en fin, transformando el pensamiento en producto y la creatividad en rendimiento. Esta cultura del desecho intelectual —donde incluso lo humano es descartable— marca un punto de inflexión que contrasta radicalmente con la historia de figuras como Ibn al-Haytham, cuyo acceso al conocimiento requería travesías heroicas que hoy se condensan en un simple prompt. La segunda parte del ensayo se adentra en el vértigo actual: una era de aceleración algorítmica donde los modelos de lenguaje se suceden sin pausa y sin comprensión ontológica. A pesar de los avances técnicos, las IAs siguen careciendo de conciencia, subjetividad o intencionalidad, razón por la cual se argumenta que toda IA aún necesita una prótesis: el ser humano. Sobre esta base, el Pensamiento Aumentado se presenta como una nueva forma de inteligencia que emerge de la sinapsis entre tres fuentes: la mente humana, los modelos de IA y la sabiduría colectiva distribuida en la web. Esta tríada no solo amplifica las capacidades cognitivas, sino que redefine la propia naturaleza de pensar: de la acumulación pasamos a la conexión; del dominio, al diálogo; del pensamiento solitario, a la sinapsis compartida. Este fenómeno no es meramente técnico, sino espiritual, ontológico y epistémico. Se perfila así una coevolución entre especies cognitivas, donde humanos e inteligencias artificiales se transforman mutuamente. La duda —reivindicada como virtud— desplaza al saber absoluto, y la interacción con el modelo se convierte en una vía de expansión consciente. Pensar juntos ya no es una posibilidad teórica, sino un destino compartido. En este nuevo paradigma, la inteligencia deja de ser un atributo individual para convertirse en fenómeno distribuido y colaborativo, al servicio de una humanidad más reflexiva, más sabia y profundamente más conectada. Esta inteligencia colectiva —humana en origen, aumentada en potencia y colectiva en destino— constituye el corazón palpitante del Pensamiento Aumentado, la verdadera puerta hacia una nueva humanidad.

description: The purpose of this study was to examine the relationship between the earnings of professional librarians and their sex, family circumstances, qualifications, years of professional experience and certain other variables (experience of unemployment, time taken to travel to work, size of town and of institution in which employed). An attempt is thus made to determine whether women librarians earn significantly less than men who are similar with regard to qualifications and other characteristics relevant to their careers.
0180 Ludwig Grote und die Moderne 1933-1959
Creators: name: Neubauer, Susanne

Year: 2017

description: The activities of German art historian Ludwig Grote (1893-1974) illuminate how cultural policy was influenced by the interaction of scholarly studies, people’s simple need to make ends meet during WWII, and the predominant promotion of certain artistic positions immediately after the war. Grote’s work should be considered in the context of recent counter-currents in the area of epistemology which try to rethink the way history has been written in the past and to reappraise German and international avant-garde art of the 1950s. By looking at Grote’s efforts for internationalization, which can be traced back through his active involvement with art in and from Brazil, this article sheds light on the problematic relationship between established narratives of Modernism and the diverse archival layers of information accessible today. Thus this discussion aims at contributing to the debate on the different perspectives necessary when writing art history today while doing justice to the transcultural aspect.

0182 Homage to Dynamism: A Contribution to the Study of the Iconography of the Machine Cult in Orphism
Creators: name: Tasić, Dragan
Publisher: name: RIHA Journal
Year: 2017

description: One of the trends in the early days of Cubism, Orphism was a style of painting that evolved in Paris during the period between 1911 and 1914. The orphists rejected the rigid principles of a non-abstract art and returned to “pure color” with the purpose of communicating their intense enjoyment. They were imbued with the new spirit and fascinated by the technological progress of the modern world. Robert Delaunay’s Homage to Blériot was painted in a state of extreme spiritual happiness, reflecting the whole atmosphere of the times. It is a testimony to the skills of the airplane constructors – the new heroes of a modern epic fantasy. World War I, however, spelled the end of the enthusiasm and optimism of the machine age.

description: Saarbrücken’s memorial cemetery for the fallen of World War I, a "war cemetery in the homeland" ("Kriegerfriedhof in der Heimat"), is an outstanding example in terms of design as well as of social history among the war cemeteries of that time. In addition to two adjacent ring systems for German and enemy casualties, the cemetery reserved fields for air raid victims, for veterans of 1870/71 (!), as well as for Muslim soldiers of the French occupying forces after the war. The directives on the creation of the tombs reflect the influences of the cemetery reform movement in Germany. The need for personal remembrance was also strongly respected and families were allowed to set up tombstones for their relatives perished in wartime. We know only few war cemeteries with a comparable “individualized” character.

description: We present the results of from DC magnetization and penetration depth measurements of cylindrical bulk large-grain (LG) and fine-grain (FG) niobium samples used for the fabrication of superconducting radio frequency (SRF) cavities. The surface treatment consisted of electropolishing and low temperature baking as they are typically applied to SRF cavities. The magnetization data were fitted using a modified critical state model. The critical current density Jc and pinning force Fp are calculated from the magnetization data and their temperature dependence and field dependence are presented. The LG samples have lower critical current density and pinning force density compared to FG samples which implies a lower flux trapping efficiency. This effect may explain the lower values of residual resistance often observed in LG cavities than FG cavities.

description: In this thesis, I conducted an analysis of the consumption patterns associated with demographic and socio-economic characteristics, using Tobit and double-hurdle models. Data were collected for 11,574 households from the US Bureau of Labor Statistics for the year of 2014. Specific determinants included household size, age, income, gender, education, race, region, marital status, and whether the household lived in a coastal state. The results reveal that seafood expenditures are sequential decisions. Asian racial groups, households headed by married couples, a large number of members in households, higher income households, and households residing in the Atlantic and Gulf Coasts were variables that significantly impacted seafood expenditures.

description: Extrasolar planets and belts of debris orbiting post-main-sequence single stars may become unbound as the evolving star loses mass. In multiple star systems, the presence or co-evolution of the additional stars can significantly complicate the prospects for orbital excitation and escape. Here, we investigate the dynamical consequences of multi-phasic, nonlinear mass loss and establish a criterion for a system of any stellar multiplicity to retain a planet whose orbit surrounds all of the parent stars. For single stars which become white dwarfs, this criterion can be combined with the Chandrasekhar Limit to establish the maximum allowable mass loss rate for planet retention. We then apply the criterion to circumbinary planets in evolving binary systems over the entire stellar mass phase space. Through about 10^5 stellar evolutionary track realizations, we characterize planetary ejection prospects as a function of binary separation, stellar mass and metallicity. This investigation reveals that planets residing at just a few tens of AU from a central concentration of stars are susceptible to escape in a wide variety of multiple systems. Further, planets are significantly more susceptible to ejection from multiple star systems than from single star systems for a given system mass. For system masses greater than about 2 Solar masses, multiple star systems represent the greater source of free-floating planets.

0165 From Italian Monuments to the Fallen of World War I to Fascist War Memorials
Creators: name: Pisani, Daniele
Publisher: name: RIHA Journal
Year: 2017

description: This paper describes the different ways of commemorating the fallen of World War I in Italy between 1918 and 1940. From the collection of examples emerges that there was no homogeneity in the forms of remembrance during these two decades. Rather, we find both a continuous renewal and overlapping of different kinds of commemorative forms. Right after the end of World War I, a spread of spontaneous local monuments is discernible, though the many small war cemeteries rising near the former battlefield areas were already beginning to be perceived as a problem. Shortly before World War II, the construction of huge ossuaries and, later, war memorials was fostered by the Fascist Regime which availed itself of the fallen for ideological and political purposes. Between these two extremes, also other forms of commemoration such as parks or avenues of remembrance were realized. This paper tries not to force coincidences between history and the history of architecture; nevertheless, it understands monuments, parks and avenues of remembrance, ossuaries, and war memorials as a kind of seismograph sensitive to the period’s shifts and jolts, and to Fascist policies in particular.

description: This paper examines the material memorialization of the World Wars in India by looking at the India Gate, the archway located at the center of the Indian national capital, New Delhi. Although dedicated to soldiers who lost their lives in World War I, the India Gate has become a symbolic commemorative monument that represents the sacrifices of all the Indian soldiers who lost their lives in the battles fought by the modern Indian state. Focusing on the multi-textured renderings of history, this paper illustrates how old memories and histories are repurposed and refashioned at the India Gate.

Causality and quantum interference in time-delayed laser-induced nonsequential double ionization

description: We perform a detailed analysis of the importance of causality within the strong-field approximation and the steepest descent framework for the recollision-excitation with subsequent tunneling ionization (RESI) pathway in laser-induced nonsequential double ionization (NSDI). In this time-delayed pathway, an electron returns to its parent ion, and, by recolliding with the core, gives part of its kinetic energy to excite a second electron at a time $t^{\prime}$. The second electron then reaches the continuum at a later time $t$ by tunneling ionization. We show that, if $t^{\prime}$ and $t$ are complex, the condition that recollision of the first electron occurs before tunnel ionization of the second electron translates into boundary conditions for the steepest-descent contours, and thus puts constraints on the saddles to be taken when computing the RESI transition amplitudes. We also show that this generalized causality condition has a dramatic effect in the shapes of the RESI electron momentum distributions for few-cycle laser pulses. Physically, causality determines how the dominant sets of orbits an electron returning to its parent ion can be combined with the dominant orbits of a second electron tunneling from an excited state. All features encountered are analyzed in terms of such orbits, and their quantum interference.

0200 (Dis)Figuration of Memory In, Around, and Beyond Gerhard Richter's Atlas: Between Photography, Abstraction, and the Mnemonic Construction
Creators: name: Mesquita Duarte, Miguel
Publisher: name: RIHA Journal
Year: 2018

description: Gerhard Richter’s Atlas is a collection of photographs and sketches that the artist started to assemble in 1961. This article aims to demonstrate that Holocaust imagery plays a unique and irreplaceable function in Atlas, creating paths throughout the project and pointing towards some of Richter’s most important ideas and contexts within which his pictorial work comes into being. The article places particular emphasis on the photographs assembled in panels 807 and 808 of Atlas, which are the basis for Richter’s series of abstract paintings entitled Birkenau paintings, from 2014. The article argues the importance of this series, making a case for a different interpretation of Atlas’s dynamics, and pointing out alternative ways of addressing the tensions between photography and painting – and, in particular, figuration and abstraction – that pervade Richter’s practice. The themes concerning Richter’s position on photography and the role played by the medium in the pictorial exploration of the traumatic past are thoroughly discussed in the article, generating new insights into the concept of the historical image in the work of the German artist.

description: We study the structural characteristics of complex networks using the representative eigenvectors of the adjacent matrix. The probability distribution function of the components of the representative eigenvectors are proposed to describe the localization on networks where the Euclidean distance is invalid. Several quantities are used to describe the localization properties of the representative states, such as the participation ratio, the structural entropy, and the probability distribution function of the nearest neighbor level spacings for spectra of complex networks. Whole-cell networks in the real world and the Watts-Strogatz small-world and Barabasi-Albert scale-free networks are considered. The networks have nontrivial localization properties due to the nontrivial topological structures. It is found that the ascending-order-ranked series of the occurrence probabilities at the nodes behave generally multifractally. This characteristic can be used as a structural measure of complex networks.

0196 The Romanticized Māori – Māori Portraits on Late 19th- and Early 20th-Century Postcards and Photographs
Creators: name: Thode-Arora, Hilke
Publisher: name: RIHA Journal
Year: 2018

description: In New Zealand, daguerrotypes since the 1850s and later on wet-plate photography already had Māori portraiture as an important motif. The 1860s saw a dramatic rise in cartes de visite, and since the late nineteenth and early twentieth century, photos and postcards representing Māori men, women and children boomed. Mainly produced by Pākehā (European settler) photographers for a Pākehā audience, these portraits depicted Māori in a stereotypical way which also characterised photography on the Pacific Islands of the time: often propped with emblematic weapons or jewellery, men were staged as fierce warriors, women either as innocent belles or, like men, as very old, often with the allusion of a ‘dying race’. New Zealand tourism, especially in the Rotorua area with its thermal attractions, was thriving by the 1890s and brought along a souvenir production which already proved so large and lucrative that it was partly outsourced to companies in Germany. Cartes de visite and postcards were sent overseas in large numbers, evidence for 1909 shows a peak of nine million cards posted from New Zealand. Their impact as a form of popular media must have been immense, creating and perpetuating stereotyped images of Māori people in Aotearoa (the Māori name for New Zealand) and all over the Western world. However, the 1890s brought an increasing acceptance and appropriation of photographs by Māori people themselves. Especially in the tangi mourning ceremonies, photos of the deceased took a prominent part. Furthermore, the photos of important ancestors were given their place in the whare whakairo meeting houses.

description: About 45,000 years ago, symbolic and technological complexity of human artefacts increased drastically. Computer simulations of Powell, Shennan and Thomas (2009) explained it through an increase of the population density, facilitating the spread of information about useful innovations. We simplify this demographic model and make it more similar to standard physics models. For this purpose, we assume that bands (extended families) of stone-age humans were distributed randomly on a square lattice such that each lattice site is randomly occupied with probability p and empty with probability 1-p. Information spreads randomly from an occupied site to one of its occupied neighbours. If we wait long enough, information spreads from one side of the lattice to the opposite site if and only if p is larger than the percolation threshold; this process was called "ant in the labyrinth" by deGennes 1976. We modify it by giving the diffusing information a finite lifetime, which shifts the threshold upwards.

description: Although it remains a tea consuming nation, both production and consumption of coffee in China has been increasing at double-digit rates and is not expected to slow down (International Coffee Organization (ICO), 2015). With investments and upward trends in production and rapid increases in consumption of coffee in China it is important for producers and retailers of the bean1 in China to understand the new Chinese coffee consumer. Using survey data from Wuhan, China we help understand the Chinese coffee consumer by explaining their consumption using standard OLS regression. Results show that whether or not consumers make/brew their own coffee, how long consumers have been consuming coffee regularly, the size of the coffee cup most often purchased and individuals’ prediction of their coffee consumption in the following year are all important in explaining Chinese coffee consumption. We suggest for long-run success, that Chinese coffee producers and retailers in China focus on the quality of their coffee bean.

description: SN 2002es is a peculiar subluminous Type Ia supernova (SN Ia) with a combination of observed characteristics never before seen in a SN Ia. At maximum light, SN 2002es shares spectroscopic properties with the underluminous SN 1991bg subclass of SNe Ia, but with substantially lower expansion velocities (~6000 km/s) more typical of the SN 2002cx subclass. Photometrically, SN 2002es differs from both SN 1991bg-like and SN 2002cx-like supernovae. Although at maximum light it is subluminous (M_B=-17.78 mag), SN 2002es has a relatively broad light curve (Dm15(B)=1.28 +/- 0.04 mag), making it a significant outlier in the light-curve width vs. luminosity relationship. We estimate a 56Ni mass of 0.17 +/- 0.05 M_sun synthesized in the explosion, relatively low for a SN Ia. One month after maximum light, we find an unexpected plummet in the bolometric luminosity. The late-time decay of the light curves is inconsistent with our estimated 56Ni mass, indicating that either the light curve was not completely powered by 56Ni decay or the ejecta became optically thin to gamma-rays within a month after maximum light. The host galaxy is classified as an S0 galaxy with little to no star formation, indicating the progenitor of SN 2002es is likely from an old stellar population. We also present a less extensive dataset for SN 1999bh, an object which shares similar observed properties. Both objects were found as part of the Lick Observatory Supernova Search, allowing us to estimate that these objects should account for ~2.5% of SNe Ia within a fixed volume. We find that current theoretical models are unable to explain the observed of characteristics of SN 2002es.

description: Within the Landau paradigm of continuous phase transitions, ordered states of matter are characterized by a broken symmetry. Although the broken symmetry is usually evident, determining the driving force behind the phase transition is often a more subtle matter due to coupling between otherwise distinct order parameters. In this paper we show how measurement of the divergent nematic susceptibility of an iron pnictide superconductor unambiguously distinguishes an electronic nematic phase transition from a simple ferroelastic distortion. These measurements also reveal an electronic nematic quantum phase transition at the composition with optimal superconducting transition temperature.

Die Zeugnisse des 12. Jahrhunderts überliefern Erinnerungen an die Geschichte Muris und schweigen sich gleichzeitig über gewisse Aspekte aus, weshalb nach den Momenten der Instrumentalisierung von Erinnerung gefragt wird und Deutungsstrategien ermittelt werden. Die Vergangenheit des Klosters zeigt sich dabei als aufs engste mit der Geschichte der frühen Habsburger verknüpft, die zur Zeit der Gründung und Reform Muris im burgundisch-schwäbischen Grenzraum agierten, und wird zugleich in den institutionellen und kirchenpolitischen Kontext des hochmittelalterlichen römisch-deutschen Reiches eingebettet.

description: We use statistically validated networks, a recently introduced method to validate links in a bipartite system, to identify clusters of investors trading in a financial market. Specifically, we investigate a special database allowing to track the trading activity of individual investors of the stock Nokia. We find that many statistically detected clusters of investors show a very high degree of synchronization in the time when they decide to trade and in the trading action taken. We investigate the composition of these clusters and we find that several of them show an over-expression of specific categories of investors.

description: Using the isospin dependent quantum molecular dynamics model, we study the effect of charge asymmetry and isospin dependent cross-section on different aspects of elliptical flow. Simulations have been carried out for the reactions of $^{124}X_{m}+^{124}X_{m}$, where m = (47, 50, 53, 57 and 59) and $^{40}X_{n}+^{40}X_{n}$, where n= (14, 16, 18, 21 and 23). Our study shows that elliptical flow depend strongly on the isospin of cross-section. The transition energy remains almost constant with increase in N/Z of the system. A good agreement is obtained with experimental measurements.

description: The isorotation contours of the solar convective zone (SCZ) show three distinct morphologies, corresponding to two boundary layers (inner and outer), and the bulk of the interior. Previous work has shown that the thermal wind equation together with informal arguments on the nature of convection in a rotating fluid could be used to deduce the shape of the isorotation surfaces in the bulk of the SCZ with great fidelity, and that the tachocline contours could also be described by relatively simple phenomenology. In this paper, we show that the form of these surfaces can be understood more broadly as a mathematical consequence of the thermal wind equation and a narrow convective shell. The analysis does not yield the angular velocity function directly, an additional surface boundary condition is required. But much can already be deduced without constructing the entire rotation profile. The mathematics may be combined with dynamical arguments put forth in previous works to the mutual benefit of each. An important element of our approach is to regard the constant angular velocity surfaces as an independent coordinate variable for what is termed the "residual entropy," a quantity that plays a key role in the equation of thermal wind balance. The difference between the dynamics of the bulk of the SCZ and the tachocline is due to a different functional form of the residual entropy in each region. We develop a unified theory for the rotational behavior of both the SCZ and the tachocline, using the solutions for the characteristics of the thermal wind equation. These characteristics are identical to the isorotation contours in the bulk of the SCZ, but the two deviate in the tachocline. The outer layer may be treated, at least descriptively, by similar mathematical techniques, but this region probably does not obey thermal wind balance.

description: We construct a class of solutions to the Cauchy problem of the Klein-Gordon equation on any standard static spacetime. Specifically, we have constructed solutions to the Cauchy problem based on any self-adjoint extension (satisfying a technical condition: "acceptability") of (some variant of) the Laplace-Beltrami operator defined on test functions in an $L^2$-space of the static hypersurface. The proof of the existence of this construction completes and extends work originally done by Wald. Further results include the uniqueness of these solutions, their support properties, the construction of the space of solutions and the energy and symplectic form on this space, an analysis of certain symmetries on the space of solutions and of various examples of this method, including the construction of a non-bounded below acceptable self-adjoint extension generating the dynamics.

description: The limitation on the shareability of quantum entanglement over several parties, the so-called monogamy of entanglement, is an issue that has caught considerable attention of quantum informa- tion community over the last decade. A natural question of interest in this connection is whether monogamy of correlations is true for correlations other than entanglement. This issue is examined here by choosing quantum deficit, proposed by Rajagopal and Rendell, an operational measure of correlations. In addition to establishing the polygamous nature of the class of three qubit sym- metric pure states characterized by two distinct Majorana spinors (to which the W states belong), those with three distinct Majorana spinors (to which GHZ states belong) are shown to either obey or violate monogamy relations. While the generalized W states can be mono/polygamous, the generalized GHZ states exhibit monogamy with respect to quantum deficit. The issue of us- ing monogamy conditions based on quantum deficit to witness the states belonging to SLOCC inequivalent classes is discussed in the light of these results.

description: Rare-earth based scintillators in general and lanthanum bromide (LaBr_3) in particular represent a challenging class of materials due to pronounced spin-orbit coupling and subtle interactions between d and f states that cannot be reproduced by standard density functional theory (DFT). Here a detailed investigation of the electronic band structure of LaBr_3 using the quasi-particle self-consistent GW (QPscGW) method is presented. This parameter-free approach is shown to yield an excellent description of the electronic structure of LaBr_3. Specifically it is able to reproduce the band gap, the correct level ordering and spacing of the 4f and 5d states, as well as the spin-orbit splitting of La-derived states. The QPscGW results are subsequently used to benchmark several computationally less demanding techniques including DFT+U, hybrid exchange-correlation functionals, and the G_0W_0 method. Spin-orbit coupling is included self-consistently at each QPscGW iteration and maximally localized Wannier functions are used to interpolate quasi-particle energies. The QPscGW results provide an excellent starting point for investigating the electronic structure of excited states, charge self-trapping, and activator ions in LaBr_3 and related materials.

description: We show that the sensor self-localization problem can be cast as a static parameter estimation problem for Hidden Markov Models and we implement fully decentralized versions of the Recursive Maximum Likelihood and on-line Expectation-Maximization algorithms to localize the sensor network simultaneously with target tracking. For linear Gaussian models, our algorithms can be implemented exactly using a distributed version of the Kalman filter and a novel message passing algorithm. The latter allows each node to compute the local derivatives of the likelihood or the sufficient statistics needed for Expectation-Maximization. In the non-linear case, a solution based on local linearization in the spirit of the Extended Kalman Filter is proposed. In numerical examples we demonstrate that the developed algorithms are able to learn the localization parameters.

description: We consider a quantum field which is in a Hartle-Hawking state propagating in a spherically symmetric black hole space-time. We calculate the components of the stress tensor, renormalized using the Hadamard form of the Green's function, in the exterior region of this space-time. We then specialize these results to the case of the `lukewarm' Riessner-Nordstrom-de Sitter black hole.

description: We perform a Bayesian parameter inference in the context of resonantly damped transverse coronal loop oscillations. The forward problem is solved in terms of parametric results for kink waves in one-dimensional flux tubes in the thin tube and thin boundary approximations. For the inverse problem, we adopt a Bayesian approach to infer the most probable values of the relevant parameters, for given observed periods and damping times, and to extract their confidence levels. The posterior probability distribution functions are obtained by means of Markov Chain Monte Carlo simulations, incorporating observed uncertainties in a consistent manner. We find well localized solutions in the posterior probability distribution functions for two of the three parameters of interest, namely the Alfven travel time and the transverse inhomogeneity length-scale. The obtained estimates for the Alfven travel time are consistent with previous inversion results, but the method enables us to additionally constrain the transverse inhomogeneity length-scale and to estimate real error bars for each parameter. When observational estimates for the density contrast are used, the method enables us to fully constrain the three parameters of interest. These results can serve to improve our current estimates of unknown physical parameters in coronal loops and to test the assumed theoretical model.

description: Using the isospin dependent quantum molecular dynamics model, we study the effect of charge asymmetry and isospin dependent cross-section on nuclear stopping and multiplicity of free nucleons and LMF's. Simulations were carried out for the reactions $^{124}X_{m}+^{124}X_{m}$, where m varies from 47 to 59 and for $^{40}Y_{n}+^{40}Y_{n}$, where n varies from 14 to 23. Our study shows that nuclear stopping as well as the production of LMF's depend strongly on the isospin of the cross-section.
