Motivated by the industry practice of pairs trading, we study the optimal timing strategies for trading a mean-reverting price spread. An optimal double stopping problem is formulated to analyze the timing to start and subsequently liquidate the position subject to transaction costs. Modeling the price spread by an Ornstein–Uhlenbeck process, we apply a probabilistic methodology and rigorously derive the optimal price intervals for market entry and exit. As an extension, we incorporate a stop-loss constraint to limit the maximum loss. We show that the entry region is characterized by a bounded price interval that lies strictly above the stop-loss level. As for the exit timing, a higher stop-loss level always implies a lower optimal take-profit level. Both analytical and numerical results are provided to illustrate the dependence of timing strategies on model parameters such as transaction costs and stop-loss level.

Az elmúlt néhány évtizedben a szabványosítás terén igen komoly változások mentek végbe. Ugrásszerűen megnőtt a szabványok száma, és jelentősen átalakult a szabványosítás folyamata is. Ezzel párhuzamosan a téma gazdasági hatásaival foglalkozó kutatások száma is megsokszorozódott, ami elsősorban a hálózati externáliák irodalmának robbanásszerű gyarapodásának köszönhető. Jelen tanulmány – az elméletek fősodrától eltérően – a tranzakciós költségek elméletében (TKE) helyezi el a szabványosítást. A szabványok és a tranzakciós költségek kapcsolatáról már születtek korábban is tanulmányok, de ezek a szabványoknak a tranzakciós költségekre gyakorolt hatásaira fókuszáltak. A tanulmány ezzel szemben arra helyezi a hangsúlyt, hogy azonosítsa a tranzakciós költségeknek a szabványosításra gyakorolt hatásait. A kutatás célja, hogy olyan elméleti alapot adjon, amelyben a témakör átfogóan elemezhető. A fő kutatási kérdés az, hogy mitől függ az, hogy melyik mechanizmus kereteiben érdemes a szabványosítást lebonyolítani. ________ Significant changes have characterized the last few decades of standardization. The number of standards has dramatically increased and processes of standardization have also changed a lot. At the same time the amount of researches that are concerned with the economic impact of standardization has also multiplied due to the boom in the literature of network externalities. Unlike the mainstream, this paper places standardization in the theory of transaction cost economics. Although there are earlier papers that are concerned with the relationship between standards and transaction costs, these studies focus on the impact of standards on transaction costs. In contrast, this paper lays emphasis on the identification of the impact of transaction costs on standardization. This study aims to provide a theoretical basis for the comprehensive analyses. The main research question: What determines which coordination mechanism is used to evolve a standard?

This article deals with the theoretical basis for the design of a motorcycle frame such as the geometry of the motorcycle, the choice of the shape of the frame and the choice of material for the manufacture of the frame. The article is devoted to the use of simulation tools to detect critical points in the design using Autodesk Inventor 2020 software. The results of the simulations were used in the production of a real frame for an electric motorcycle.

During the early years of independence (1990s), agricultural and institutional changes in Uzbekistan were made based on the specific characteristics of our country. During transformation, almost nothing has changed in terms of effectivity in regards to transformation of state farms to collective farms still did not make these farms profitable. Only with the formation of dehkan farms (a form of individual farming) after 2004 did agricultural entities started becoming profitable. How can this be explained? Why are these agricultural forms of management more efficient and coincide with the mentality of our population? In this article, using the neo-institutional theory, we have discussed these questions in an attempt to answer these questions by justifying a theoretical point. This theory shows that major issue property rights and transaction costs play main role in the definition of forms of farms management. Statistical analysis of transaction costs and local specifics resulted in a conclusion that the dehkan farming form has significant advantages.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Various methods of video-enhanced microscopy combine TV cameras with light microscopes creating images with improved resolution, contrast and visibility of fine detail, which can be recorded rapidly and relatively inexpensively. The AVEC (Allen Video-enhanced Contrast) method avoids polarizing rectifiers, since the microscope is operated at retardations of λ/9- λ/4, where no anomaly is seen in the Airy diffraction pattern. The iris diaphram is opened fully to match the numerical aperture of the condenser to that of the objective. Under these conditions, no image can be realized either by eye or photographically. Yet the image becomes visible using the Hamamatsu C-1000-01 binary camera, if the camera control unit is equipped with variable gain control and an offset knob (which sets a clamp voltage of a D.C. restoration circuit). The theoretical basis for these improvements has been described.

Difflugia lobostoma is a shelled amoeba. The shell is an external structure of considerable mass which presents the animal with special restrictions in cell locomotion which are met by the development of active pseudopodial lobopodia containing, apparently, an organized system of thick and thin microfilaments (Eckert and McGee-Russell, 1972). The shell is constructed of sand grains picked up from the environment, and cemented into place with a secretion. There is a single opening through which lobopods extend. The organization of the shell was studied by scanning electron microscopy (SEM).Intact shells or animals with shells were dried by the critical point method of Anderson (1966) or air dried, after primary fixation in glutaraldehyde.

This report describes an unusual and persistent dysphonia in two young women who had taken a therapeutic regimen of isotretinoin for intractable acne. We report perceptual and instrumental data for their dysphonia, and pose a theoretical basis for the relationship of dysphonia to this drug. We also provide recommendations for reducing the risk of acquiring a dysphonia during the course of treatment with isotretinoin.
