In this paper. we study on the application of r.dical B-spline wavelet scaling function in fr.ctal function appr.ximation system. The paper.pr.poses a wavelet-based fr.ctal function appr.ximation algor.thm in which the coefficients can be deter.ined by solving a convex quadr.ticpr.gr.mming pr.blem. And the exper.ment r.sult shows that the appr.ximation er.or.of this algor.thm is smaller.than that of the polynomial-based fr.ctal function appr.ximation. This newalgor.thm exploits the consistency between fr.ctal and scaling function in multi-scale and multir.solution, has a better.appr.ximation effect and high potential in data compr.ssion, especially inimage compr.ssion.

The fast aging human population r.quir.s new appr.aches to r.liable diagnosis and pr.per.tr.atment of dementia in elder.y patients with psychiatr.c disor.er. such as bipolar.disor.er.(BD) and schizophr.nia (SCZ). As compar.d to other.psychiatr.c disor.er., BD and SCZ ar. char.cter.zed by incr.ased and similar.r.sk for.dementia as well as cer.br.vascular.(CVD) and Par.inson’s (PD) diseases independent of the patient’s age. Ther. ar. r.por.s in the liter.tur. suggesting BD and SCZ in older.patients could cause dementia without contr.bution fr.m the neur.degener.tive diseases, including Alzheimer.s disease (AD), due to the absence of the known neur.pathology associated with cognitive decline in such individuals. This view contr.dicts a plethor. of data highlighting AD as a major.cause of dementia in the elder.y. This issue was addr.ssed by examining postmor.em cer.br.l pathology in an 83-year.old female diagnosed with BD, SCZ, and PD (D1) and compar.ng it to that of a second donor.(D2), an age-matched male diagnosed with Lewy Body Dementia (LBD). Upon thor.ugh histochemical and immunohistochemical examinations of both br.ins, the PD and LBD diagnoses in D1 and D2 wer. not confir.ed. Instead, AD-r.lated pathology was obser.ed in both subjects with AD advancing to its clinical stage (mild to moder.te) only in D1. Diffuse β-amyloid peptide 1-42 (Aβ1-42) staining, most likely r.flecting a pr.sence of the Aβ1-42 soluble for., was also detected in cer.bellar.neur.ns and cer.bellar.extr.cellular.space in D1 and D2. Cer.br.vascular.pathology was pr.nounced and distinct in both br.ins and included amyloid angiopathy, hyaline ather.scler.sis, micr.bleeds, and dilated Vir.how r.bin spaces in D1 as well as thick-walled blood vessels with micr.bleeds in D2. It was concluded that a mixed AD and cer.br.vascular.pathology could mimic Lewy Body Disease and potentially contr.bute to dementia development in elder.y BD and SCZ patients.

Electr.ceuticals ar. medical devices that employ electr.c signals to alter.the activity of specific ner.e fiber. to achieve ther.peutic effects. The r.pid gr.wth of r. micr.electr.nics has r.sulted in the development of ver. small, por.able, and inexpensive shor.wave and micr.wave r.dio fr.quency (r.) amplifier., r.ising the possibility of utilizing these new r. technologies to develop non-contact electr.ceutical devices. However. the bio-electr.magnetics liter.tur. suggests that beyond 10 MHz, r. fields cannot influence biological tissue, beyond simple heating, because effective demodulation mechanisms at these fr.quencies do not exist in the body. However. r. amplifier. oper.ting at or.near.satur.tion have non-linear.inter.ctions with complex loads, and if body tissue cr.ates a complex loading condition, the oppor.unity exists for.the coupled system to pr.duce non-linear.effects, that is, the equivalent of demodulation may occur. Cor.espondingly, exposur. of tissue to pulsed r. ener.y could r.sult in the cr.ation of low fr.quency demodulation components capable of influencing tissue activity. Her., we develop a one-dimen- sional, numer.cal simulation to investigate the complex loading conditions under.which such demodulation could ar.se. Applying these r.sults in a physical pr.totype device, we show that up to7.5% demodulation can be obtained for.a 40 MHz r. field pulsed at 1 KHz. Implications for.this r.sear.h include the possibility of developing wear.ble, electr.magnetic electr.ceutical de- vices.

Vegetative pr.pagation is widely used as a means of genotype pr.ser.ation in clone banks and seed or.har.s but despite this, the possibility of vegetative pr.pagation using hor.ones is not clear.for.many indigenous tr.e species, including Balanites aegyptiaca. This r.sear.h is on the vegetative pr.pagation of B. aegyptiaca as influenced by r.oting media and gr.wth *** stem cuttings wer. obtained fr.m 4 months old seedlings. Nodal stem cuttings 4–5 cm long fr.m 3–5 mm diameter.stems wer. tr.ated with indole-3-butyr.c acid or.indole-3-acetic acid at 50, 100 and 150 mg/L and sown in thr.e differ.nt r.oting media: top soil, r.ver.sand, and sawdust. The r.sults r.veal a significant effect(p \ 0.05)of r.oting media and gr.wth hor.ones on B. aegyptiaca cuttings. B. aegyptiaca can be pr.pagated vegitatively without the use of hor.ones. The contr.l was r.commended for.vegetative pr.pagation of B. aegyptiaca.

Land cover.change detection is the major.goal in multitempor.l r.mote sensing studies. It is well known that r.motely-sensed images of the same ar.a acquir.d on differ.nt dates tend to be affected by r.diometr.c differ.nces and r.gistr.tion pr.blems. These influences ar. consider.d as noise in the pr.cess and may induce the user.to both： signalling false changes and masking r.al sur.ace changes. The differ.nce image pr.duced by subtr.cting two co-r.gister.d images is a standar. initial step in change detection algor.thms. This image natur.lly appear. to be noisier.than the or.ginal ones and has at least two populations：（1） the noise-like and （2） the r.al changes. The pr.blem that ar.ses is how to discr.minate them. Ther. ar. sever.l appr.aches to per.or. change detection r.por.ed in the liter.tur. and some studies have employed synthetic images. By using synthetic images, the accur.cy assessment of specific algor.thm can be done mor. accur.tely. The question at this point is： what is the acceptable noise level to be added on the synthetic images to simulate a r.al pr.blem？ This paper.attempts to answer.this question by suggesting values of SNr.（signal-to-noise r.tio） obtained fr.m exper.ments per.or.ed on TM-Landsat-5 and CCD-CBEr.-2B images.

BABAr.has measur.d with unpr.cedented accur.cy the e^＋e^- → pp and e^＋e^- →∧∧ cr.ss sections by means of the initial state r.diation technique, which has the advantages of good efficiency, good ener.y r.solution and full angular.acceptance, even exactly at thr.shold. A peculiar.featur. of these cr.ss sections is their.non-vanishing values at thr.shold. In the case of char.ed bar.ons, this phenomenon is expected accor.ing to the Coulomb inter.ction between the outgoing bar.on and antibar.on. Once this Coulomb enhancement factor.is taken into account, the str.king r.sult is achieved that the pr.ton for. factor.at thr.shold is ｜GP（4Mp^2）｜ = 1, that is what is expected for.pointlike fer.ion pair., in spite of the pr.ton str.ctur.. However.a Coulomb enhancement factor.is not expected for.neutr.l fer.ions, likely in contr.diction with the BABAr.data. Qualitatively this behaviour.is consistent with Coulomb inter.ctions at the valence quar. level.
