I would like to introduce my self. My name is Agung Trisetyarso. I was born in Jakarta on 19 th May 1976. I had finished my studies from kindergarden (TK Triguna), elementary school (SD Triguna, from 1983 to 1989), junior high school (SMPN 11, from 1989 to 1992) to high school (SMA 82, from 1992 to 1995) in Jakarta. After finishing my high school study, I continued my study to physics department in Bandung Institute of Technology located at Ganesha street, Dago, North Bandung. While I am studying at ITB, I had a lot of interesting experience, like I was involved in many kinds of student activities, student movement in 1998, and I also had a lot of facilities to study physics. I had finished undergraduate (1995-2000) and graduate (2000-2002) studies from ITB physics department.
First, the truly truth is always invariant respect to time and places. For example, everything in our environment will be influenced by earth gravity and involved by time.
Second, every phenomenon in our nature always can be described by mathematics. Why ? Because I believe that there is a creator creating our universe with the precisely.
Third, everything came from one source and will be back to one source again.So, there are always connections one to each others in our universe.
You see, it is our goal as theoretical physicist... representing all kind of our nature behavior in mathematics...and it would be better if we have only one kind of algebra. What kind of algebra which will be so fit to describe our nature ? Actually, I don't know. If I know it, of course every Professor from Princeton will visit my home.
I think, there are several candidates which will be very challenging in the next decades :
Introduction: Cell locomotion plays a central role in many biological phenomena, as there are embryogenesis,inflammation, wound healing, and during the growth of axons. Although the molecular components participating in the regulation of cell motility are known to a large extend, their cooperativity and their formation of a signaling network is poorly understood. In general, it is assumed that the locomotion of biological cells is based on signal-mediated polymerization of their cytoskeletons. Recently, it has been shown using computer simulations and theoretical considerations, that the persistency of the random motion and the chemotaxis of a cell is basically due to the autocatalytic polymerization kinetics of the cytoskeletal actin network. It has been demonstrated how substrate coupling and energy supply, under which the motion is performed, leads together with polymerization processes to a general concept of cell motility. However, in all the considerations the biochemical network of cellular proteins (among others, Arp2/3, cofilin, gelsolin, profilin, capZ) which regulates the polymerization of the cytoskeleton has been not taken into account explicitly. This aspect can be very crucial since these proteins may change the rate constants of polymerization and may change the geometry of the cytoskeletal network which hence determine among others velocity and direction of cell locomotion.
Proposal: What I want to study is the influence of polymerization-regulating proteins on cell motility and cell locomotion. In particular, I want to address the question whether a dynamical network of interacting cellular proteins, including a feedback control cycle, similar as found for bacterial chemotaxis, can regulate efficiently the concentration of the polymerization-regulating proteins in space in time and hence control velocity and direction of cell locomotion. The long range achievement of my study is to develop a self-consistent model for cell locomotion which can contribute from a biophysical point of view to our understanding of biological phenomena as are there are embryogenesis, inflammation, wound healing, and the growth of axons.
Scientific Methods: Cellular models, ranging from the molecular to the coarse-grained description will be developed and studied using mathematical methods and computer simulations. Starting from previous studies, I will extend these investigations and include explicitly the concentrations, varying in space and time, of Arp2/3 and other regulatory proteins. Based on a certain set of regulatory proteins, a dynamical control cycle will be constructed, similar as in studies of bacterial chemotaxis. Brownian dynamics and Monte Carlo simulations will be applied to the cellular model in order to investigate various properties as cell velocity, orientation of motion, cellular distributions of concentrations, etc.

Abstract: The emerging of quantum logic gates is the consequences of mixing between reversible logic gate and operator in quantum theory. Quantum theory imposes that every operator must be invariant with respect to unitary and similarity transformations. Those transformations affect to the requirement of quantum logic gates, that it must be decomposable to many irreducible representation represented by identity and unitary operator.
Degeneracy Breaking of Hydrogen Atom

Abstract:The three dimensional rotation group, SO(3), is a symmetry group of the normal hydrogen atom. Each reducible representation of this group can be associated with a degenerate energy level. If this atom is placed in an external magnetic field, the interaction between the orbital magnetic moment with this field will lead to a symmetry breaking where the symmetry group of the atom is a new group distinct from the SO(3) group. This phenomenon describes the normal Zeeman effect, where a degenerate energy level splits into several new energy levels. It is explicitly shown that each of the new energy levels can be associated with an irreducible representation of the new symmetry group.
Application of Darboux Transformation to Solve Multisoliton Solution on Nonlinear SchrÖdinger Equation
(Undergraduate Final Project, Adviser : Alexander Iskandar Ph.D)

Abstract: Darboux transformation is one of the methods used in solving nonlinear evolution equation. Basically, the Darboux transformation is a linear algebra formulation of the solutions of the Zakharov-Shabat system of equations associated with the nonlinear evolution equation. In this Final Project, the evolution of monochromatic electromagnetic wave in a nonlinear-dispersive optical medium is considered. Using the Darboux transformation, explicit multisoliton solutions (one to three soliton solutions) are obtained from a trivial initial solution.
