How do you value companies which have IPOed recently? How do you compare them amongst their peers? Valuing companies using a linear extrapolation of their revenues and profits leads to an ingenious method to benchmark stocks against each other. Here we present such a method, dubbed the growth average U1. The Appendix includes MySQL code to calculat...

How can you measure the strength of a growth stock? Can this be quantified? Here’s a way to help measure it using concepts from digital signal processing. You can purchase the single article online from the publisher (http://www.traders.com) and help them out. Its a good technical magazine and they send worldwide if you are interested in a print+o...

Benjamin Graham introduced a very simple formula for valuing a growth stock in 1962. How does it work and why? What is a sensible way to calculate this across many stocks and provide a scoring system to compare stocks amongst each other? We are presenting a methodology here which is put into practice.

We have come across many questions from people regarding trend following. To a lay person this is shrouded in mystery and often confused with prediction methods, which are regarded as dubious rightly so. How are you able to predict anything with confidence especially if it's a highly complex system where there are no governing equations, even if it...

“The trend is your friend” is a common saying, the difficulty lies in determining if and when you are in a trend. Is the trend strong enough to trade? When does the trend reverse and how are you going to determine this? We will try and answer at least some of these questions here. We are deriving a novel indicator to measure the power of a trend us...

In this paper we provide an in-depth analysis of the socalled Arms Index (aka. TRIN) which is named after Richard Arms who introduced this technical indicator in 1967. It became a fundamental indicator widely used and published in online and print media, Wall Street Journal and CNBC for example. The index is used as a market breadth indicator, used...

This is the second part of our research on the Arms Index which was published in “The Arms Index aka TRIN” (DOI) and it defines and introduces an improvement of the regular Arms Index calculation. We highlight the flaws of the existing Arms Index calculation which is so widely referenced and propose an weighted and normalized Index that that is not...

Michaelis and Menten devised their model for enzyme kinetics in 1913. Various linearization schemes such as the Lineweaver‐Burk approximation have become popular. An explicit solution using the Lambert W function has been presented but remains widely unknown among bioscientists. By computer simulation, we studied the effects of two sources of measu...

You have seen the ARMS Index mentioned on the NYSE Big Board, CNBC, WSJ and various other places. It is often referred to as TRIN, but how is it calculated? What are its peculiarities and how can it be improved? We are going to take a critical look at the existing ARMS Index and offer an optimization of the calculation.

In the context of enteral feeding in children the influence on growth and the question of fat resorption is of great interest. We, therefore, measured the thickness of subcutaneous body fat in a sample of long-term enterally fed toddlers and healthy controls. In 33 long-term enterally fed toddlers (10 girls, 23 boys) and 275 healthy controls (128 g...

Background Using Monte Carlo simulations, we compare different methods (maximizing Youden index, maximizing mutual information, and logistic regression) for their ability to determine optimum binary cut-off thresholds for a ratio-scaled diagnostic test variable. Special attention is given to the stability and precision of the results in dependence...

Aim: Evaluation of anthropometry and subcutaneous body fat on long--term enterally--fed children during tube weaning. Prospective cohort study: Pre--post--test design. Methods: The LIPOMETER, an optical device, was used to measure the thickness of subcutaneous adipose tissue (SAT) layers (in mm). The specification of 15 evenly--distributed body...

In renal patients estimation of GFR is routinely done by means of population-based formulae using serum creatinine levels. For GFR determination in the creatinine-blind regions or in cases of reno-hepatic syndrome as well as in critical cases of live kidney donors individualized measurements of GFR (mGFR) employing the kinetics of exogenous filtrat...

Question
Dear Experts,
we do want to use the old WATERS 996 PAD with EzChrom Elite and a Shimazu Pump.
Unfortunately the aquistions of the data do not work and we think that we need to trigger it from the other equipment. More over to connect the other equipement to the Waters 996 PDA we need a suitable cable connector for the Waters 996 PDA (see attachemnt).
Can anyone here mind telling me where we could get this cable or/and connector ?
Question
I would be happy if someone could give me some references to work (esp. Masterthesis) dealing with the problem of chemical milling of titanium. In particular for etching for wire fabrication. Thanks
