We present some exact integrability.cases of the extended Liénard equation y.′+ f(y.(y.)n +k(y.(y.)m + g(y.y.+ h(y. = 0, with n > 0 and m > 0 arbitrary.constants, while f(y., k(y., g(y., and h(y. are arbitrary.functions. The solutions are obtained by.transforming the equation Liénard equation to an equivalent first kind first order Abel ty.e equation given by.v/dy. f(y.v3-n+ k(y.v3-m+ g(y.v2+ h(y.v3, with v = 1/y..As a first step in our study.we obtain three integrability.cases of the extended quadratic-cubic Liénard equation,corresponding to n = 2 and m = 3, by.assuming that particular solutions of the associated Abel equation are known. Under this assumption the general solutions of the Abel and Liénard equations with coefficients satisfy.ng some differential conditions can be obtained in an exact closed form. With the use of the Chiellini integrability.condition, we show that if a particular solution of the Abel equation is known, the general solution of the extended quadratic cubic Liénard equation can be obtained by.quadratures. The Chiellini integrability.condition is extended to generalized Abel equations with g(y. ≡ 0 and h(y. ≡ 0, and arbitrary.n and m, thus allowing to obtain the general solution of the corresponding Liénard equation. The application of the generalized Chiellini condition to the case of the reduced Riccati equation is also considered.

SubceUular localization is pivotal for RNAs and proteins to implement biological functions. The localization diversity.of protein interactions has been studied as a crucial feature of proteins, considering that the protein-protein interactions take place in vari- ous subceltutar locations. Nevertheless, the localization diversity.of non-coding RNA （ncRNA） target proteins has not been sy.- tematically.studied, especially.its characteristics in cancers. In this study. we provide a new algorithm, non-coding RNA target localization coefficient （ncTALENT）, to quantify.the target localization diversity.of ncRNAs based on the ncRNA-protein interaction and protein subcellular localization data. ncTALENT can be used to calculate the target localization coefficient of ncRNAs and measure how diversely.their targets are distributed among the subcellular locations in various scenarios. We focus our study.on long non-coding RNAs （IncRNAs）, and our observations reveal that the target localization diversity.is a primary.characteristic of IncRNAs in different bioty.es. Moreover, we found that IncRNAs in multiple cancers, differentially.expressed cancer IncRNAs, and IncRNAs with multiple cancer target proteins are prone to have high target localization diversity. Furthermore, the analy.is of gastric cancer helps us to obtain a better understanding that the target localization diversity.of IncRNAs is an important feature closely.related to clinical prognosis. Overall, we sy.tematically.studied the target localization diversity.of the IncRNAs and uncovered its association with cancer.
