Mean square optimal hedging strategies for (B,S) financial market

Presented by Corr. Member of the Academy N. Vakhania, March 9, 1998

Abstract. We defined financial (B,S) - market in the following way: the stock price Sn = S0 exp{Mn - < M > n} n ³ 0 and interest rate r = 0, where M is the Gaussian martingale with compensator < M >. For the European contingent claim f(SN) we constructed hedging strategies optimal in the sense of the following square criterion inf pÎSFE(f(SN) - xpn)2, where XNp is the wealth process.

Presented by Corr. Member of the Academy D. Baladze, December 30, 1998

Abstract. In the present paper we consider a class of subsemigroups from BX, whose every semigroup has as its right unit the quasi-order relation on the set X.

investigation of photo-stimulated diffusion processes in III-V Semiconductors

Presented by Member of the Academy J. Lominadze, March 19, 1998

Abstract. The paper presents the results of investigation of photo-stimulated diffusion (PSD) processes from continuous source in the GaAs, GaAlAs and GaP during formation of ohmic contacts, p-n junctions, p+ and n+ areas and insulation regions. It is shown, that during PSD along with the temperature the role of the ionization factor is very significant. It is suggested, that in the III-V compounds the atoms of the III group might be more mobile during pulse-photon irradiation and probability of vacancy generation in these points might be higher in comparison with the points of the V group atoms.

Investigation of the Suspension Process in the Manganese

Dioxide Electrosynthesis

Presented by Corr. Member of the Academy L. Japaridze, march 30, 1998

Abstract. The influence of suspension of the fine-suspended particles into the acidic manganese sulphate electrolyte solution during electrosynthesis of the manganese dioxide, on the quality of the product and current efficiency, on the values of anodic potential and bath voltage, was investigated. It was shown that suspension of manganese-containing particles, as well as of graphite and inert materials - glass and corundum, results in considerable increase of titanium electrode resistance towards passivation: at 2 A/dm2 current density the anodic potential and the bath voltage retained stable values. The overal picture of incorporation of the supspended particles into the electrode deposite and their total expenditure are evaluated. It was found that EMD specimens obtained in such conditions contain mainly g-MnO2, which could be utilized in a current sources as a cathode material, unlike e-MnO2 obtained in the same conditions but in the non-suspension bath.

Presented by Corr. Member of the Academy N. Aleksidze, March 30, 1998

Abstract. The lectins distribution in the subcellular fractions of Triticale leaves was established (plasmalemma, microsomes, mitochondria, chloroplasts, nuclei). Only membrane proteins have been characterized by lectin activity in all analyzed subcellular fractions. The high lectin content was revealed in chloroplasts and low lectin content - in mitochondrial fraction. The plasmalemmma and microsomes lectins carbohydrate-binding specificity displayed highest sensitivity to N-acetyl-D-galactosamine, D-glucose, D-dezoxi-D-glucose and lactose, but chloroplast lectins - to lactose and D-galacturonic acid and mitochondrial and nuclei lectins had no specificity to any tested sugars (16 analyzed sugars).

Study of Temperature Action on Structural Properties of Titin Molecule Using Intrinsic Fluorescence and Calorimetry Methods

Presented March 23, 1998

Abstract. Native titin preparation has been obtained by the Trinick method. The action of temperature on structural properties of titin has been studied using the intrinsic fluorescence method. It is shown that amino acid residues of tryptophane and tyrosine play a key role in spectra intensity of the intrinsic fluorescence of titin. It is shown that a rise in temperature from 40°C to 60°C results in a sharp change of fluorescence intensity and a shift of spectra to the long wave range. The calorimetry method was used to study thermal denaturation of titin. The protein under question is not found to have a thermodynamically stable state.

Presented by Member of the Academy N.Kipshidze, May 4, 1998

Abstract. We have examined heart functional indices of 21 patients with soft and moderate forms of essential hypertension (EH) undergone irregular hypertension treatment. Examinations were carried out by EKG and Dopler echocardiographic methods. It appeared, that on the background of irregular (actually unsystematic) treatment even in case of hypertension effect the final diastole volume of LV doesn’t change essentially. Mean indices of left auricle area and right ventricle final diastole diameter increase which is a result of overtension of lesser circle blood vessels.

The Taxonomic Position of Udabnopithecus garedziensis Burtsh. et Gabash. (Udabno Georgia) and its geological age.

Presented February 22, 1998

Abstract. A new view on Late Miocene Hominoid Udabnopithecus garedziensis Burtsh. et Gabash. from Udabno(East Georgia) as discussed. The maxilla fragment of Udabnopithecus in size and general morphological features closely resembles the hominoid genus Dryopithecus. The particular morphological traits of the Udabnopithecus with relatively late stratigraphic and isolated geographic position in the Trans-Caucasus region may afford a separate taxonomic classification of Dryopithecus garedziensis.If our estimate of age (8-8,5 million years) is correct Dryopithecus garedziensis appears to be one of the youngest known Dryopithecines in Eurasia.

The Function of the Tree in the Ritual of Blood Sacrifice

Presented by Corr. Member of the Academy R. Gordeziani, April 27, 1999

Abstract. All lives belong to God. It comes from him and to him it returns, and when he wants it he takes it. But it differs otherwise from true sacrifice where man makes an offer of his own accord. Since in most sacrifices men eat the carcass of the victim, what is God supposed to receive? We hypothesize that burning of the victim was an important and necessary part in the rituals of blood sacrifice.
