For mice, natural fluorescence is composed of endogenous fluorescence from organs like the skin, the bladder, etc. and from ingested food. The discrimination between the two kinds of fluorescence makes easy monitoring the targeted tissues. Generally, the amplitude of the fluorescence signal depends on the location and on the amount of injected fluorophore, which is limited in in-vivo experiments. This paper exposes some results of natural fluorescence analysis from in-vivo mice experiments using a time domain small animal fluorescence imaging system: eXplore OptixTM. Fluorescence signals are expressed by a Time Point Spread Function (TPSF) at each scan point. The study uses measures of similarity applied purposely to the TPSF to evaluate the discrepancy and/or the homogeneity of scanned regions of a mouse. These measures allow a classification scheme to be performed on the TPSF's based on their temporal shapes. The work ends by showing how the exogenous fluorescence can be distinguished from natural fluorescence by using the TPSF temporal shape.

On the other hand, Prof. Miguel Gutiérrez Gaitán, presented his plans, vision, and main ideas about the future of the Chapter, with focus on the development of internationalization and student branches. Among the planned activities for the present term, the IEEE ComSoc Chile Chapter is glad to announce the technical sponsorship for the 2023 South American Conference on Visible Light Communications (SACVLC), to be held at the Universidad of Santiago de Chile (USACH), between November 8 and 10, 2023. Moreover, the IEEE ComSoc Chile Chapter is enthusiastic on participating in the 2023 ComSoc Sister Chapters Program Project, led by Prof. Mohab Mangoud and Prof. Ricardo Veiga, which will greatly benefi t IEEE student branches worldwide. Lastly, also in the line of the internationalization plan, the whole new ExCom of IEEE ComSoc Chile Chapter is joining eff orts in bringing to Chile, two IEEE ComSoc Distinguished Lecture Tours (DLTs) among diff erent academic institutions, including UNAB, UDP, and USACH, among others. To conclude, the IEEE Chile ComSoc Chapter invite all the local, regional, and international community to contact the new Chair, Prof. Miguel Gutiérrez Gaitán (miguel.gutierrez@unab. cl) to joint eff orts and organize together further virtual, in-person, and hybrid activities around communication technology to "advance communications and networking technology for the betterment of humanity."

First, the error-free gaps in a permuted error pattern are studied. It is shown that the gap-lengths in any two permuted error patterns are related by a linear mapping. Based on the characteristics of error-free gaps, the capability of multiple-step (T,U) permutation decoding of (n,k,2t+1) cyclic codes with odd t is examined. The bounds on the code rate of permutation-decodable binary cyclic codes are subsequently derived. It is shown that the code rate can be increased by increasing the number of U-permutations. For a permutation-decodable (n,k,2t+1) cyclic code, there is an optimum permutation step which makes the largest increase in its code rate. Examples are also given to illustrate the applications of the analytical results

Using their properties, we can define the capability of the s-step (T, U) permutation decoding method. These properties can also be extended to other permutation decoding methods which use the elements other than p (the characteristic of GF(q)) as multipliers

In this paper, the topic of permutation decoding using primitive elements of a prime field as multipliers is addressed in order to increase the capability of the well known (T, U) permutation decoding method in decoding cyclic codes of prime length. Since only error positions are involved in the analysis, the results are applicable to cyclic codes over GF(2q).

Since 1962 several improved error-trapping methods have been devised in an effort to extend the capability and effectiveness in decoding multipleerror-correcting cyclic codes. Prarige and MacWilliains introduced a (T, U) permutation group applied to this errortrapping decoding strategy by making use of a set of codepreserving permutation to obtain k error-free positions from which the rest of the code word could be reconstructed. Recently, exact lower bounds on the code length n for (n, k, % + I) cyclic codes have been found by using 2-step and 3step (T, U) permutation groups. This paper presents a study on the relationship between the code parameters n, k, t and the number of permutation steps s, with 1 being odd. Some examples on the capability of (T, U) perniutation decodable (PD) cyclic codes are illustrated.

Through this process two distinct errors (note that e,(x) = e,(x)) have been obtained. This is the error Case 3 in which the received word is in two decoding spheres. As previously discussed, the error that has the higher probability should be chosen. The user has to make a decision. In this example, it is assumed that the probability of a burst error of length un is less than the probability of a burst error length of U,, where un > U,. Therefore, the e2(x> should be chosen.
