In the present paper we have studied the Finslerian Hypersurface and Randers Change of Finsler metric. We have also proved that Randers change makes three types of hypersurfaces invariant under certain condition. These three type of hypersurfaces are hyperplanes of first, second and third kind.

Studying an (α, β)-metrics is a central idea in Finsler geometry, whichis a generalization of Randers metric. In this paper, we have derived the Cartanconnection for the Finsler space whose metric is given by h-Randers exponentialchange and also obtained the condition under which the Finslerian hypersurface tobe hyperplane of first, second and third kind.

In this paper, we find the necessary and sufficient conditions under which two classes of (α, β)-metrics, i.e. generalized Randers change (G.R.C.) exponential metric F = α exp(β/α) + ϵβ and Randers metric F˜ = ˜α + β˜ are projectively related. Note that α and ˜α are Riemannian metrics, β and β˜ are 1-forms on a manifold M with dimension n > 2 and ϵ ̸= 0 is a constant. Furthermore, we study this projective relation when F has special curvature properties.

In this paper, we find a condition under which a Finsler space with Randers change of mth-root metric is projectively related to a mth-root metric and also we find a condition under which this Randers transformed mth-root Finsler metric is locally dually flat. Moreover, if transformed Finsler metric is conformal to the mth-root Finsler metric, then we prove that both of them reduce to Riemannian metrics.

A Finsler space is said to have reversible geodesics if for any of its oriented geodesic paths, the same path traversed in the opposite sense is also a geodesic. In [6] the conditions for a Randers space to have reversible geodesics have been found. The main goal of this paper is to find conditions for a Finsler space endowed with an (α, β)-metric to be with reversible geodesics or strictly reversible geodesics, respectively. Moreover, we obtain some new classes of (α, β)-metrics with reversible geodesics and show how new Finsler metrics with reversible geodesics can be constructed by means of

This work is a continuation of the paper [Generalized beta-conformal change of Finsler metrics, Int. J. Geom. Meth. Mod. Phys. 7(4) (2010) 565–582]. In the present paper, we investigate the change of Finsler metrics [Formula: see text] which we refer to as a generalized β-conformal change. Under this change, we study some special Finsler spaces, namely, quasi-C-reducible, semi-C-reducible, C-reducible, C2-like, S3-like and S4-like Finsler spaces. We obtain some characterizations of the energy β-change, the Randers change and the Kropina change. We also obtain the transformation of the T-tensor

Abstract Mammalian females are born with a finite supply of follicles within their ovaries that may be related to fertility and reproductive longevity. The number of microscopic follicles in the ovarian cortex is positively correlated to the number of antral follicles. In cattle, the number of antral follicles can be determined by ultrasonographic examination of the ovaries, is repeatable within a female, and has a moderate heritability. Studies in rodents suggest that nutritional status early in life can alter structure and function of the ovarian reserve, resulting in changes in follicle num

Noise predictions models are utilized in an increasing range of decision-making applications.

30 normal, young adults of superior intellectual ability were administered either 0.2 mg/kg diazepam (p.o.) or a lactose placebo to assess the effects of diazepam upon short- and long-term verbal recall of pictorially depicted common objects. A recognition task was used to determine the presence of differences between groups and between visual recognition and verbal recall. The memory tasks employed were a combination of three of Randt's Memory Test Picture Recognition subtests in which black line-drawings are used to depict common objects. Diazepam did not reduce verbal recall significantly i

This paper investigates asymmetry in US housing price cycles at the state and metropolitan statistical area (MSA) level, using the Triples test (Randles, Flinger, Policello, &amp; Wolfe, 1980) and the Entropy test of Racine and Maasoumi (2007). Several reasons may account for asymmetry in housing prices, including non-linearity in their determinants and in behavioural responses, in particular linked to equity constraints and loss aversion. However, few studies have formally tested the symmetry of housing price cycles. We find that housing prices are asymmetric in the vast majority of cases

New Zealand's existing law and policy is not adequate to provide for appropriate adaptation to the effects of climate change. There have been widespread calls for law reform, particularly to the laws affecting local government decision-making on the adoption of climate adaptation mechanisms, such as the Resource Management Act 1991 (RMA). The author is one researcher who has identified the need for law reform in this area, focusing on the (in)ability of the RMA to deal with the adaptation necessary to handle the expected effects of sea-level rise.

DNA electrochemical biosensors represent a feasible alternative for the diagnosis of different pathologies. In this work, the development of an electrochemical method for Human Papillomavirus-16 (HPV-16) sensing is reported based on potential relaxation measurements related to the discharge of a complex double layer of a DNA-modified gold electrode. The method used allows us to propose an equivalent circuit (EC) for a DNA/Au electrode, which was corroborated by electrochemical impedance spectroscopy (EIS) measurement. This model differs from the Randles circuit that is commonly used in double-

The development of a simple and low cost electrochemical impedance immunosensor based on screen printed gold electrode for rapid detection of Escherichia coli in water is reported. The immunosensor is fabricated by immobilizing anti-E. coli antibodies onto a gold surface in a covalent way by the photochemical immobilization technique, a simple procedure able to bind antibodies upright onto gold surfaces. Impedance spectra are recorded in 0.01 M phosphate buffer solution (PBS) containing 10 mM Fe(CN)63−/Fe(CN)64− as redox probe. The Nyquist plots can be modelled with a modified Randles circuit,

The effect of substitution on the aromatic ring of aniline and in its amino group on the potential of polymerization in aqueous medium and on the charge passed during polymerization was studied. The formation of polymer films on the working electrode and their electrochromic changes were also examined. From the electro-oxidation of aniline, the number of reversible and irreversible steps, the number of electrons exchanged and the type of oxidation mechanism were found.

Electrochemical impedance spectroscopy techniques were applied in this work to nine industrially fabricated lead–acid battery prototypes, which were divided into three type/technology packages. Frequency-dependent impedance changes were interpreted during successive charge/discharge cycles in two distinct stages: (1) immediately after fabrication and (2) after a controlled aging procedure to 50% depth of discharge following industrial standards. To investigate their state of health behavior vs. electrical response, three methods were employed, namely, the Q-Q0 total charge analysis, the decay

The values of the diffusion coefficient of the reagents (MenFc and MenFc+) of redox systems have been calculated by the Randles-Sevcik equation, which are consistent with the conclusion that "a one-electron reversible electrochemical reaction is determined by the diffusion of the reagents".

Ionically conductive mortar is a new Portland cement-based construction material prepared by permeating electrolyte solution into porous mortar specimen. The conductive mechanism of ionically conductive mortar is the directional movement of internal free ions under external electric field. Because of the strong electrochemical properties of ionically conductive mortar, electrochemical workstation was used to test the performance of ionically conductive mortar. The open-circuit potential during the permeation process of ionically conductive mortar was tested. The results show that the change of

A longstanding question in obstructive airway disease is whether observed changes in mucin composition and/or posttranslational glycosylation are due to genetic or to environmental factors. We tested whether the mucins secreted by second-passage primary human bronchial epithelial cell cultures derived from noncystic fibrosis (CF) or CF patients have intrinsically different specific mucin compositions, and whether these mucins are glycosylated differently. Both CF and non-CF cultures produced MUC5B, predominantly, as judged by quantitative agarose gel Western blots with mucin-specific antibodie
