The short distance behavior of baryon-baryon potentials defined throughNambu-Bethe-Salpeter wave functions is investigated using the operator product expansion.In a previous analysis of the nucleon-nucleon case, corresponding to the SU(3) channels27s and 10a, we argued that the potentials have a repulsive core. A new feature occursfor the case of baryons made up of three flavors: manifestly asymptotically attractive potentialsappear in the singlet and octet channels. Attraction in the singlet channel wasfirst indicated by quark model considerations, and recently been found in numerical latticesimulations. The latter have however not yet revealed asymptotic attraction in the octetchannels; we give a speculative explanation for this apparent discrepancy.

Light-cone gauge superstring theory in noncritical dimensions corresponds to a worldsheet theory with nonstandard longitudinal part in the conformal gauge. The longitudinal part of the worldsheet theory is a superconformal field theory called X ± CFT. We show that the X ± CFT combined with the super-reparametrization ghost system can be described by free variables. It is possible to express the correlation functions in terms of these free variables. Bosonizing the free variables, we construct the spin fields and BRST invariant vertex operators for the Ramond sector in the conformal gauge formulation. By using these vertex operators, we can rewrite the tree amplitudes of the noncritical light-cone gauge string field theory, with external lines in the (R,R) sector as well as those in the (NS,NS) sector, in a BRST invariant way.

We show that a source which radiates in the vacuum of the strongly coupled N = 4=4 SYM theory produces an energy distribution which, in the supergravity approximation, has the same space-time pattern as the corresponding classical distribution: the radiation propagates at the speed of light without broadening. We illustrate this on the basis of several examples: a small perturbation propagating down a steady string, a massless particle falling into AdS5, and the decay of a time-like wave-packet. A similar observation was made in Phys. Rev. D81 (2010) 126001 for the case of a rotating string. In all these cases, the absence of broadening is related to the fact that the energy backreaction on the boundary arises exclusively from the bulk perturbation at, or near, the boundary. This is so since bulk sources which propagate in AdS5 at the speed of light do not generate any energy on the boundary. We interpret these features as an artifact of the supergravity approximation, which fails to encode quantum mechanical fluctuations that should be present even in the strong coupling limit. We argue that such fluctuations should enter the dual string theory as longitudinal string fluctuations, which are not suppressed at strong coupling. We heuristically estimate the effects of such fluctuations and argue that they restore the broadening of the radiation, in agreement with expectations from both quantum mechanics and the ultraviolet/infrared correspondence.

We study gluon scattering amplitudes/Wilson loops in =4 super Yang-Mills theory at strong coupling by calculating the area of the minimal surfaces in AdS 3 based on the associated thermodynamic Bethe ansatz system. The remainder function of the amplitudes is computed by evaluating the free energy, the T- and Y-functions of the homogeneous sine-Gordon model. Using conformal field theory (CFT) perturbation, we examine the mass corrections to the free energy around the CFT point corresponding to the regular polygonal Wilson loop. Based on the relation between the T-functions and the g-functions, which measure the boundary entropy, we calculate corrections to the T-and Y-functions as well as express them at the CFT point by the modular S-matrix. We evaluate the remainder function around the CFT point for 8 and 10-point amplitudes explicitly and compare these analytic expressions with the 2-loop formulas. The two rescaled remainder functions show very similar power series structures.

We consider the dimensional regularization of the light-cone gauge type II superstring field theories in the NSR formalism. In the previous work, we have calculated the tree-level amplitudes with external lines in the (NS, NS) sector using the regularization and shown that the desired results are obtained without introducing contact term interactions. In this work, we study the tree-level amplitudes with external lines in the Ramond sector. In order to deal with them, we propose a worldsheet theory to be used instead of that for the naive dimensional regularization. With the worldsheet theory, we regularize and define the tree-level amplitudes by analytic continuation. We show that the results coincide with those of the first quantized formulation.

The purpose of this paper is to consider the view of technology in Heidegger. The technology is in the domain of the truth. Heidegger identifies the technology with the manifestation of the truth.The modern technology is also the manifestation of the truth. Man makes the nature the object by the modern technology. Man discloses a secret of the nature in order to take out the wealth in front of him. In other words the manifestation of the modern technology appears in the object of nature. The autonomy of the modern technology exist in this kind of the process of the manifestation. Heidegger calls all the setup of the modern technology the assembly (Gestell). We have free-dom to steer the technology. The freedom isn't the simple option. There isn't the doom, but the destiny in the technology. Man doesn't escape from this reign of assembly. Heidegger's philosophy prompts to reflect the wishful thinking of the humanism.

Right after WWII, Eastern European countries stood at a crossroads, witnessing, to name but a couple, communization of the state and transfer of millions of ethnic minorities, most notably Germans. Postwar Czechoslovakia was no exception. Czechoslovakia had had three republican periods: the first republic from its independence in 1918 to the collapse in 1938, the second from 1938 to the Nazi occupation in 1939, and the third from 1945 to the beginning of Communist Party rule in 1948. The third republic in particular embraced many alternatives for future social policies, neither capitalistic nor communistic. Focusing on the housing policy from 1945 to 1948, this article aims to elucidate postwar Czechoslovakia's search for the optimum social policies, addressing the difference between the prewar and the postwar period. I also examine the policy of the transfer of the German population and the settlement of Czechs in the Czech border area, as it was against this backdrop that the new housing policy took form. While the last president of the first republic, Eduard Beneš, returned as president of the new Czechoslovakia, the Communist Party was dominant in the government. On the one hand, the new republic resembled its prewar predecessors in terms of parliamentary democracy. On the other hand, undertaking the nationalization of large enterprises, land reform, and a planned economy, the postwar government attempted to differentiate itself from the prewar regime that had resulted in the Nazi's invasion and the collapse of the state. The Communists as the largest group in the government could propose their own postwar reforms disposed not toward Soviet-type socialism, but toward "the Czechoslovakian way" or "the bridge between the East and the West." The highest on the agenda for postwar reconstruction was the housing policy. The postwar government launched a "two-year plan," the first planned economy for the reconstruction of Czechoslovakia. Notably, the government planned to build and supply 125,000 houses from 1947 to 1948. The government and architects worked in tandem to upgrade the poor prewar housing conditions by revising prewar housing laws. On the one hand, socialist parties and architects criticized the prewar liberalist housing market, exhorting the introduction of state control of the market. Some architects were enthusiastic about grand apartment buildings containing small houses as the socialist type of housing of the future. On the other hand, based on the housing law of 1921, the government decided to provide subsidies for family houses with 80 m2 of floor space, instead of 34 m2 as had been stipulated in 1937, with a view toward improving the housing environment. Moreover, the new government adhering to the Czechoslovakian way, neither liberalist nor socialist, even allowed private properties, while some architects influenced by Soviet architecture insisted on the entire socialization of houses and land. It is definitely necessary to contextualize the postwar Czechoslovakian housing policy in the removal of more than 2,000,000 Germans and the settlement of Czech people in the borderland (pohraniči). There, the "settlement office (Osidlovací úřad)" led by the Communist Party played a particularly essential role. The settlement office as well as the national board, which was also ruled by Communists, fulfilled the task of furnishing new Czech settlers with houses that had been expropriated from Germans and Hungarians as well as managing the housing market. The Communist Party had a good reason to expect support from those new settlers who could obtain huge properties, such as houses, thanks to the Communist policy. Despite the abundance of confiscated empty houses, this period did not see the solution to the housing problem, as the condition of these houses remained atrocious. Although the postwar housing policy held an opportunity to realize ideal plans for the future Czechoslovakia, it did not thrive due to the tough reality in the borderland. The policy and the ideal were consigned to oblivion after the establishment of the Communist regime in 1948.
