This simulation shows time-dependent 1D quantum bound state wavefunctions for a number of different wells. Position, momentum, parity, energy, and current can all be viewed, with phase shown with color. Eigentstates can be selected using the energy level diagram. Multiple-energy-eigenstate wavefunctions can be created through changes in the amplitude and phase of the basis states using spinors. Postion and energy measurements can be taken, resulting in new states of the system.

This simulation explores the transitions between quantum states in a number of 1D systems. The time-dependent wavefunction is displayed. An electric field resonant with the transition between states is applied and the changes in the wavefunction with time are tracked. The dipole transition probability is displayed for different initial to final state transitions, and the user may select the transition they wish to observe.

The RandomWalk1DContinuous program simulates a random walk in one dimension for steps of any length between 0 and 1. The default number of steps is N = 16 and the probability p of going to the right for a single step is 0.5. RandomWalk1DContinuous is part of a suite of Open Source Physics programs that model aspects of Statistical and Thermal Physics (STP). The program is distributed as a ready-to-run (compiled) Java archive. Double clicking the stp RandomWalk1DContinuous.jar file will run the program if Java is installed on your computer. Additional programs can be found by searching ComPADRE for Open Source Physics, STP, or Statistical and Thermal Physics.

Determination of Isotopic Abundance of 13C/12C or 2H/1H and 18O/16O in Biofield Energy Treated 1-Chloro-3-Nitrobenzene (3-CNB) Using Gas Chromatography-Mass Spectrometry

1-Chloro-3-nitrobenzene (3-CNB) is an aromatic halo-amine compound used as chemical intermediate for the production of several fine chemicals like pharmaceuticals, dyes, agricultural chemicals, etc. The stable isotope ratio analysis has drawn attention in numerous fields such as agricultural, food authenticity, biochemistry, etc. The objective of the current research was to investigate the impact of the biofield energy treatment on the isotopic abundance ratios of PM+1/PM, PM+2/PM and PM+3/PM in 3-CNB using gas chromatography – mass spectrometry (GC-MS). The sample, 3-CNB was divided into two parts – one part was denoted as control and another part was referred as biofield energy treated sample that was treated with biofield energy (The Trivedi Effect®). T1, T2, T3, and T4 were represented to different time interval analysis of the biofield treated 3-CNB. The GC-MS spectra of the both control and biofield treated 3-CNB indicated the presence of molecular ion peak [M+] at m/z 157 (calculated 156.99 for C6H4ClNO2) along with same pattern of fragmentation. The relative intensities of the parent molecule and other fragmented ions of the biofield treated 3-CNB were improved as compared to the control 3-CNB. The percentage change of the isotopic abundance ratio of PM+1/PM was significantly increased in the biofield treated 3-CNB at T1, T2 and T3 by 11.62, 18.50, and 29.82%, respectively with respect to the control 3-CNB. Accordingly, the isotopic abundance ratio of PM+2/PM in the biofield treated 3-CNB at T2 and T3 was significantly improved by 15.22 and 35.09%, respectively as compared to the control sample. The isotopic abundance ratios of PM+1/PM and PM+2/PM in the biofield treated 3-CNB at T1 and T4 were changed as compared to the control sample. The percentage change of the isotopic abundance ratio of PM+3/PM was enhanced in the biofield treated 3-CNB at T1, T2, T3, and T4 by 4.67, 18.69, 31.31 and 6.08%, respectively as compared to the control 3-CNB. The isotopic abundance ratios of PM+1/PM, PM+2/PM and PM+3/PM in the biofield treated 3-CNB changed with the time. So, the biofield energy treated 3-CNB might exhibit the altered isotope effects such as altered physicochemical and thermal properties, binding energy, and the rate of the chemical reaction as compared to the control sample. The biofield energy treated 3-CNB might assist in designing for the synthesis of pharmaceuticals, agricultural chemicals, dyes, corrosion inhibitors and other several useful industrial chemicals.

T1DBase was created jointly by the Institute for Systems Biology, the Juvenile Diabetes Research Foundation International, and the Juvenile Diabetes Research Foundation/Wellcome Trust Diabetes and Inflammation Laboratory to support the work of Type 1 diabetes (T1D) researchers. T1DBase currently "includes annotated genomic sequences for suspected T1D susceptibility regions; microarray data; functional annotation of genes active in beta cells; and 'global' datasets, generally from the literature, that are useful for systems biology studies." Information is available for human, rat, and mouse Type 1 diabetes candidate regions. The site also offers several tools including Gbrowse, Cytoscape, Beta Cell Gene Expression Bank, and Kegg Pathways. T1DBase was created as a community resource, and the website invites researchers to contribute both ideas and data.

We introduce the <i>Easy Java Simulations</i> (EJS) edition of <i>An Introduction to Computer Simulation Methods</i> and discuss the importance of computers in physics and the nature of computer simulation. Various computer languages are considered and we show how the EJS modeling and authoring tool allows us to separate the model into logical parts and to separate the model from the view. Students learn the logic of computer modeling using loops and control structures as they study algorithms used in professional practice. Students are also introduced to object-oriented programming concepts by using object properties and methods when they create user interfaces. However, little user-interface coding is required because the user interface is created automatically by EJS. <i>Easy Java Simulations</i> is built using the <a href="http://www.compadre.org/osp/">Open Source Physics</a> code library and produces XML-based source code. The use of XML is important because it enables users to describe and store the model at a high level of abstraction, thereby leaving the Java implementation to EJS. A tutorial at the end of Chapter 1 describes this process.
