It has also been demonstrated that telomere extension has successfully reversed some signs of aging in laboratory mice [41] [42] and the nematode worm species Caenorhabditis elegans.

Weinstein and Ciszek, However, longer telomeres might also protect against cancer, because short telomeres are associated with cancer. It has also been suggested that longer telomeres might cause increased energy consumption.

Techniques to extend telomeres could be useful for tissue engineering , because they might permit healthy, noncancerous mammalian cells to be cultured in amounts large enough to be engineering materials for biomedical repairs.

Two recent studies on long-lived seabirds demonstrate that the role of telomeres is far from being understood. Thus, it seems that there is much more variation in the behavior of telomere length than initially believed.

Furthermore, Gomes et al. Known, up-to-date telomere nucleotide sequences are listed in Telomerase Database website. Telomeres are critical for maintaining genomic integrity and may be factors for age-related diseases.

Observational studies have found shortened telomeres in many types of experimental cancers. Several techniques are currently employed to assess average telomere length in eukaryotic cells.

While multiple companies offer telomere length measurement services, the utility of these measurements for widespread clinical or personal use has been questioned.

Most research on telomere length and regulation, and its relationship to cancer and ageing, has been performed on mammals, especially humans, which have little or no somatic telomerase production.

Ectotherms are significantly more likely than endotherms to have variation in somatic telomerase expression. For instance, in many fish, telomerase occurs throughout the body and associated with this, telomere length is roughly the same across all its tissue.

If we deal with approximations of empirical data to create yield curves it is necessary to choose suitable mathematical functions.

The first kind are the parametric models. This type of function-based models includes the model proposed by Nelson and Siegel in and its extension by Svensson in This model was originally proposed as a curve- fitting tools as opposed to being obtained from a theoretical non-arbitrage framework.

Why is NSS more used to estimate the yield curve among other models? According to literature1 there are four reasons: Our results shows that the NSS model is a good model to replicate the behaviour of the yield curve of chinese government bonds.

We did our work assign the point by author according to the knowledge of the author in the point in question. We have used both Matlab program and excel program to do the estimations and computations and plot our charts.

Finally we introduce the conclusions we have reached by doing this paper. For every different maturity m we have a new equation.

The right figure always shows the interaction of the variables accumulated, so in this case the same figure as only one variable is considered. Figure 2 Figure 2: As expected the beginning of the curve decreased by around 1.

In this case, it decreases and then goes back to zero as m grows. In this way we add the second hump to the curve. However, even though it is possible, it is quite difficult, why in practice another approached is being used.

Empirically, the three factors are found to have a small correlation among them. Actually, it is possible to arrive to these factors supporting the analysis on principal component analysis or assuming zero correlations between them.

Figure 5 NSS System This system will be overidentified, which means that there are more knows than unknowns, and it is necessary to minimize a norm of the residuals.

A result from the numerical analysis is that the size of the minimized residual is not necessarily influenced by the conditioning of the equations.

Researches have been aware of a certain potential multicollinearity issues while estimating the NS model making difficult to estimate the parameters correctly.

It is interesting to highlight that the correlation between two regressors of the model depends on the time to maturity of the financial instruments chosen.

The problem is that for many values of lambda, the factors are highly correlated and we find that the system is badly conditioned.

The correlation also depends of the time of maturity and those series of short maturities turns out to be the most sensitive to the collinearity issue.

We can see that the maturity choice influences the steepness of the correlation curve. In the NSS-case we can observe the most obvious case. The correlation is 1 at lambda equals to 0, and rapidly decays to The interesting range is between lambda equals to 0.

The collinearity is not necessary a problem in forecasting as we can measure their combined effect. The problem is when we want to predict the regression coefficients themselves.

A well-chosen lambda should result in non-correlated coefficients. But, in case of fixing a highest lambda as needed, the result will be time series for each coefficient with strong correlations and the series will present much more volatile.

A high multicollinearity among regressors can also inflate the variance of the estimators, so that more difficult to model. In conclusion, it would be useful to restrict the lambda values where practical identification is still possible.

The VIF is defined as: The tolerance level is the reciprocal of VIF. First of all, we consider here data for a selected day as given in table Treasury Market Association in China We have exclude one bond with less than three months to maturity, because the yields on these securities often seem to behave oddly and the bonds with more than ten years to maturity has been difficult to find all information related to compute properly our following estimation.

These steps are called reflections, and they are constructed to conserve the volume of the simplex and hence maintain its nondegeneracy.

When it can do so, the method expands the simplex in one or another direction to take larger steps. Unlike modern optimization methods, the Nelder—Mead heuristic can converge to a non-stationary point unless the problem satisfies stronger conditions than are necessary for modern methods.

Many variations exist depending on the actual nature of the problem being solved. A common variant uses a constant-size, small simplex that roughly follows the gradient direction which gives steepest descent.

Visualize a small triangle on an elevation map flip-flopping its way down a valley to a local bottom. This method is also known as the Flexible Polyhedron Method.

This, however, tends to perform poorly against the method described in this article? In that case we contract towards the lowest point in the expectation of finding a simpler landscape.

However, Nash notes that finite-precision arithmetic can sometimes fail to actually shrink the simplex, and implemented a check that the size is actually reduced.

The initial simplex is important. Indeed, a too small initial simplex can lead to a local search, consequently the NM can get more easily stuck.

So this simplex should depend on the nature of the problem. Criteria are needed to break the iterative cycle.

Nelder and Mead used the sample standard deviation of the function values of the current simplex. If these fall below some tolerance, then the cycle is stopped and the lowest point in the simplex returned as a proposed optimum.

Note that a very "flat" function may have almost equal function values over a large domain, so that the solution will be sensitive to the tolerance.

Nash [6] adds the test for shrinkage as another termination criterion. Our results shows that the NSS model is a good model to replicate the behaviour of the yield curve of chinese government bonds.

The construct of Perceived Self-Efficacy reflects an optimistic self-belief Schwarzer, This is the belief that one can perform a novel or difficult tasks, or cope with adversity -- in various domains of human functioning.

Perceived self-efficacy facilitates goal-setting, effort investment, persistence in face of barriers and recovery from setbacks.

It can be regarded as a positive resistance resource factor. Each item refers to successful coping and implies an internal-stable attribution of success.

Perceived self-efficacy is an operative construct, i. The scale is unidimensional. Criterion-related validity is documented in numerous correlation studies where positive coefficients were found with favorable emotions, dispositional optimism, and work satisfaction.

Negative coefficients were found with depression, anxiety, stress, burnout, and health complaints. In studies with cardiac patients, their recovery over a half-year time period could be predicted by pre-surgery self-efficacy.
