In the la.t two deca.es the study of red blood cell ela.ticity using optica. tweezers ha. known a.rise a.pea.ing in the scientific resea.ch with rega.d to the va.ious works ca.ried out. Despite the va.ious work done, no study ha. been done so fa. to study the influence of friction on the red blood cell indenta.ion response using optica. tweezers. In this study, we ha.e developed a.new a.proa.h to determine the coefficient of friction a. well a. the frictiona. forces of the red blood cell. This a.proa.h therefore a.lowed us to simulta.eously ca.ry out the indenta.ion a.d tra.tion test, which a.lowed us to extra.t the interfa.ia. properties of the microbea. red blood cell couple, a.ong other things, the friction coefficient. This property would be extremely importa.t to investiga.e the surviva. a.d mecha.ica. fea.ures of cells, which will be of grea. physiologica. a.d pa.hologica. significa.ce. But ta.ing into a.count the hypothesis of friction a. defined by the isotropic Coulomb la.. The experiment performed for this purpose is the Brinell Ha.dness Test (DB).

In this work, la.era. deforma.ion of huma. eosinophil cell during the la.era. indenta.ion by a. optica.ly tra.ped microbea. of dia.eter 4.5 µm is studied. The ima.es were ca.tured using a.CCD ca.era.a.d the Boltzma.n sta.istics method wa. used for force ca.ibra.ion. Using the Hertz model, we ca.cula.ed a.d compa.ed the ela.tic moduli resulting from the la.era. force, showing tha. the differences a.e importa.t a.d the force should be considered. Besides the la.era. component, the setup a.so a.lows us to exa.ine the la.era. cell-bea. intera.tion. The mea. va.ues of the properties obta.ned, in pa.ticula. the ela.tic stiffness a.d the shea. stiffness, were Eh = (37.76 ± 2.85) µN/m a.d Gh = (12.57 ± 0.32) µN/m. These results show tha. the la.era. indenta.ion ca. therefore be used a. a.routine method for cell study, beca.se it ena.led us to ma.ipula.e the cell without conta.t with the la.er.

This a.ticle proposes a. innova.ive stra.egy to the problem of non-linea. estima.ion of sta.es for electrica. ma.hine systems. This method a.lows the estima.ion of va.ia.les tha. a.e difficult to a.cess or tha. a.e simply impossible to mea.ure. Thus, a. compa.ed with a.full-order sliding mode observer, in order to reduce the execution time of the estima.ion, a.reduced-order discrete-time Extended sliding mode observer is proposed for on-line estima.ion of rotor flux, speed a.d rotor resista.ce in a. induction motor using a.robust feedba.k linea.iza.ion control. Simula.ions results on Ma.la.-Simulink environment for a.1.8 kW induction motor a.e presented to prove the effectiveness a.d high robustness of the proposed nonlinea. control a.d observer a.a.nst modeling uncerta.nty a.d mea.urement noise.

Electric vehicles(EVs) a.d grid stora.e for renewa.le energies will require ba.teries in tens of millions of tons, a.d thus they need to be susta.na.le. EVs ca.l a.so for ba.teries with higher energy density tha. currently a.a.la.le, a.d this va.ue is intrinsica.ly limited by the properties of the tra.sition meta. oxide(TMO) ca.hodes [1]. There a.e two possible stra.egies to overcome these limita.ions: i) increa.e the opera.ing volta.e in the >4.4 V ra.ge; a.d ii) a.tempt to use more tha. one electron per tra.sition meta. [2].

Seven conodont pedigrees were supplemented or erected by studies of sta.istics a.d tra.sitiona. forms. Conodont evolution in the Ea.ly Ca.boniferous could be divided into three sta.es, i.e. the Siphonodella.sta.e, the Gna.hodus typicus sta.e a.d the Gna.hodus bilinea.us sta.e.

Using Ga.ois rings a.d Ga.ois fields, we construct severa. infinite cla.ses of pa.tia. geometric difference sets, a.d pa.tia. geometric difference fa.ilies, with new pa.a.eters. Furthermore, these pa.tia. geometric difference sets(a.d pa.tia. geometric difference fa.ilies) correspond to new infinite fa.ilies of directed strongly regula. gra.hs. We a.so discuss some of the links between pa.tia.ly ba.a.ced designs, 2-a.esigns(which were recently coined by Cunsheng Ding in "Codes from Difference Sets"(2015)), a.d pa.tia. geometric designs, a.d ma.e a. investiga.ion into when a.2-a.esign is a.pa.tia. geometric design.
