Intersection local times of fractional Brownian motions with as generalized white noise functionals
In , for any dimension , expansions of self-intersection local
times of fractional Brownian motions with arbitrary Hurst coefficients in
are presented. The expansions are in terms of Wick powers of white
noises (corresponding to multiple Wiener integrals), being well-defined in the
sense of generalized white noise functionals.Comment: 17 page
Searching for Communities in Bipartite Networks
Bipartite networks are a useful tool for representing and investigating
interaction networks. We consider methods for identifying communities in
bipartite networks. Intuitive notions of network community groups are made
explicit using Newman's modularity measure. A specialized version of the
modularity, adapted to be appropriate for bipartite networks, is presented; a
corresponding algorithm is described for identifying community groups through
maximizing this measure. The algorithm is applied to networks derived from the
EU Framework Programs on Research and Technological Development. Community
groups identified are compared using information-theoretic methods.Comment: 12 pages, 4 figures, to appear in "Proceedings of the 5th Jagna

Mapping of non-central potentials under point canonical transformations
Motivated by the observation that all known exactly solvable shape invariant
central potentials are inter-related via point canonical transformations, we
develop an algebraic framework to show that a similar mapping procedure is also
exist between a class of non-central potentials. As an illustrative example, we
discuss the inter-relation between the generalized Coulomb and oscillator
systems.Comment: 11 pages article in LaTEX (uses standard article.sty). Please check

GUIDED INQUIRY-BASED LEARNING OF TRIGONOMETRIC IDENTITIES
The implementation of K-12 basic education curriculum brought some concerns in the educational sector of the Philippines such as shortage in teaching and learning materials, and the required teaching-learning approach that would cater for the development of 21st century skills among learners. This study developed and validated guided inquiry-based learning materials in understanding the trigonometric identities in Grade 11 Pre-calculus to promote self-directed, independent, and inquiry-based learning, and to verify its effects in student learning. The guided inquiry-based learning materials underwent evaluation and validation, and were evaluated as Highly Acceptable to teachers and students. This study utilized the descriptive method using the 7-point scale. Quasi-experimental design was adopted to measure the effects of the validated learning materials and the use of inquiry-based learning in student’s performance. Results confirmed that students are equally able to develop cognitive skills in trigonometric identities through IBL and conventional learning modality. Thus, the validated guided inquiry-based materials developed and used in this study can be adopted in its original form to promote 11th graders’ self-directed, independent, and inquiry learning necessary for developing 21st century skills such as critical thinking. 
Path Integral Discussion for Smorodinsky-Winternitz Potentials: I.\ Two- and Three Dimensional Euclidean Space
Path integral formulations for the Smorodinsky-Winternitz potentials in two-
and three-dimen\-sional Euclidean space are presented. We mention all
coordinate systems which separate the Smorodinsky-Winternitz potentials and
state the corresponding path integral formulations. Whereas in many coordinate
systems an explicit path integral formulation is not possible, we list in all
soluble cases the path integral evaluations explicitly in terms of the
propagators and the spectral expansions into the wave-functions.Comment: LaTeX 60 pages, DESY 94-01
Polynomial Solution of Non-Central Potentials
We show that the exact energy eigenvalues and eigenfunctions of the
Schrodinger equation for charged particles moving in certain class of
non-central potentials can be easily calculated analytically in a simple and
elegant manner by using Nikiforov and Uvarov (NU) method. We discuss the
generalized Coulomb and harmonic oscillator systems. We study the Hartmann
Coulomb and the ring-shaped and compound Coulomb plus Aharanov-Bohm potentials
as special cases. The results are in exact agreement with other methods.Comment: 18 page
Describing the on-the-job training experiences of bachelor of science in management accounting students
This study aims to describe the on-the-job training experiences of BSMA students at Saint Columban College, Pagadian City. A single case study was most appropriate for the research’s proper conduct since this study wants to describe and understand the on-the-job training of BSMA students who experience this program. The findings led the researchers to the conclusion that the research participants described their on-the-job training as a journey of learning, growth, and application of their academic knowledge to the real-world context of accounting and management fields. They expressed a sense of practicality and hands-on learning, emphasizing the transition from theoretical concepts to practical applications. Their narratives show the importance of concrete experiences within their training, followed by reflective observations that allow them to derive meaningful insights. The development of abstract conceptualizations and stage of active experimentation highlights the value of these experiences in shaping their professional skills and development
The generalized MIC-Kepler system
This paper deals with dynamical system that generalizes the MIC-Kepler
system. It is shown that the Schr\"{o}dinger equation for this generalized
MIC-Kepler system can be separated in spherical and parabolic coordinates. The
spectral problem in spherical and parabolic coordinates is solved.Comment: 8 page
