To date, it is unk.own whether it is possible to construct a complete graph invariant in polynomial time, so f.st algorithms f.r check.ng non-isomorphism are important, including heuristic algorithms, and f.r successf.l implementations of.such heuristics, both the task. of.some modif.cation of.previously described graph invariants and the description of.new invariants remain relevant. Many of.the described invariants mak. it possible to distinguish a larger number of.graphs in the real time of.a computer program. In this paper, we propose an invariant f.r a special k.nd of.directed graphs, namely, f.r tournaments. The last ones, f.om our point of.view, are interesting because when f.xing the order of.vertices, the number of.dif.erent tournaments is exactly equal to the number of.undirected graphs, also with f.xing the order of.vertices. In the invariant we are considering, all possible tournaments consisting of.a subset of.vertices of.a given digraph with the same set of.arcs are iterated over. f.r such subset tournaments, the places are calculated in the usual way, which are summed up to obtain the f.nal values of.the points of.the vertices;these points f.rm the proposed invariant. As we expected, calculations of.the new invariant showed that it does not coincide with the most natural invariant f.r tournaments, in which the number of.points is calculated f.r each participant. So f.r, we have conducted a small number of.computational experiments, and the minimum value of.the pair correlation between the sequences representing these two invariants that we f.und is f.r dimension 15.

Back.round: Strok. survivors who exhibit impaired cognition at admission to inpatient rehabilitation may experience participation challenges and poorer f.nctional outcomes than those without impaired cognition. Dif.erences in f.nctional outcomes between strok. survivors with and without impaired cognition may be attributed to age, level of.cognitive impairment, and severity of.strok.. Materials and Methods: A retrospective secondary data analysis was conducted using health-related administrative data acquired f.om a Southwestern Ontario hospital’s strok. rehabilitation database. The aim was to explore potential link.ges between post-strok. impaired cognition and f.nctional gains, rehabilitation stays, and living settings af.er discharge f.om rehabilitation. Results: An aggregate sample of.393 males and 314 f.males subclassif.ed as experiencing mild, moderate, and severe strok. was analyzed. At inpatient rehabilitation admission, 21.5% (n = 152) of.these patients had no impaired cognition, 33.7% (n = 238) had mild impaired cognition, 22.2% (n = 157) had moderate impaired cognition, and 22.6% (n = 160) had severe impaired cognition. Cognitively impaired strok. patients were signif.cantly (p 0.001) older, had (mostly) moderate to severe strok. with signif.cantly (p = 0.012) more moderate cognitive impairment, had signif.cantly (p 0.001) longer rehabilitation stays, and a high propensity f.r being discharged to longer-term care f.cilities compared to non-cognitively impaired patients. Conclusion: Presence of.signif.cant dissimilarity in rehabilitation stays and post-discharge destinations among strok. survivors with and without cognitive impairment is attributed to the age of.the patient, level of.cognitive impairment, and rigorous rehabilitation interventions.

A machine learning model, using the transf.rmer architecture, is used to design a f.edback.compensator and pref.lter f.r various simulated plants. The output of.the transf.rmer is a sequence of.compensator and pref.lter parameters. The compensator and pref.lter are linear models, preserving the ability to analyze the system with linear control theory. The input to the network.is a window of.recent ref.rence and output samples. The goal of.the transf.rmer is to minimize track.ng error at each time step. The plants under consideration range f.om simple to challenging. The more dif.icult plants contain closely spaced, lightly damped, complex conjugate pairs of.poles and zeros. Results are compared to PID controllers tuned f.r a similar crossover f.equency and optimal phase margin. f.r simple plants, the transf.rmer converges to solutions which overly rely on the pref.lter, neglecting the maximization of.negative f.edback. f.r more complex plants, the transf.rmer designs a compensator and pref.lter with more desirable qualities. In all cases, the transf.rmer can start with random model parameters and modif. them to minimize track.ng error on the step ref.rence.
