The hypoxic-ischemic encephalopathy in neonates is a neurological disorder
characterized by the lack of oxygen (hypoxia) and low blood flow (ischemia),
often related to perinatal asphyxia due to complications during birth. The main
treatment for hypoxic-ischemic encephalopathy in neonates is the cooling of
affected regions. Systemic cooling can be achieved by wrapping the body of the
neonate with a blanket containing channels through which cold water is
circulated. Alternatively, local cooling can be performed by surrounding the
head of the neonate with a cap, in which cold water flows through channels,
while the remaining body can be warmed by a radiator in the incubator. This
seminar summarizes the works recently performed by the authors on the solution
of inverse problems and predictive control related to the hypothermia treatment
of the hypoxic-ischemic encephalopathy in neonates. The inverse problem
involved the estimation of the brain temperature from the information provided
by other temperature measurements available during the treatment. The inverse
problem was solved as a state estimation problem with the Sampling Importance
Resampling (SIR) algorithm of the particle filter method. The solution of the
inverse problem was verified with simulated measurements, and ultimately
validated with actual experimental data obtained during the local cooling
treatment of a neonate in a pediatric intensive care unit. The combined
application of the particle filter method and stochastic model predictive
control was also numerically examined, in order to observe and control the body
temperatures during the cooling treatment of a neonate.</span></p>

Sums of subsets of R^n, Z^n and Z_p^n have been studied for well over a
century, although at the beginning progress was very slow. The subject took off
in the 1960s, when Erdos and Heilbronn, and Freimann published their celebrated
papers, and has been going from strength to strength with the results of
Gowers, Green, Károlyi, Ruzsa, Tao, Vu and others. The talk, which should be
understandable to a wide audience, not only to pure mathematicians, will
contain some of the results I have obtained with Imre Leader and Marius Tiba,
together with a recent breakthrough achieved by Gowers, Green, Manners and Tao.</span></p></div></div><div id="m_6033269669396082776m_8094493278995216294m_-500557569034922272DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br><table style="border-top:1px solid #d3d4de"><tbody><tr><td style="width:55px;padding-top:13px"><a href="https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail" target="_blank"><img src="https://s-install.avcdn.net/ipm/preview/icons/icon-envelope-tick-round-orange-animated-no-repeat-v1.gif" alt="" width="46" height="29" style="width:46px;height:29px"></a></td><td style="width:470px;padding-top:12px;color:#41424e;font-size:13px;font-family:Arial,Helvetica,sans-serif;line-height:18px">Não contém vírus.<a href="https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail" style="color:#4453ea" target="_blank">www.avast.com</a></td></tr></tbody></table><a href="#m_6033269669396082776_m_8094493278995216294_m_-500557569034922272_DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2" width="1" height="1"></a></div>
