We cons.der the mos. general s.atic s.herically s.mmetric black hole metric. The accretion of the fluid flow around the Van der Waal's.black hole is.inves.igated and we calculate the fluid's.four-velocity, the critical point and the s.eed of s.und during the accretion proces.. We als. analyze the nature of the univers.'s.dens.ty and the mas. of the black hole during accretion of the fluid flow. The dens.ty of the fluid flow is.als. taken into account. We obs.rve that the mas. is.related to reds.ift. We compare the accreting power of the Van der Waal's.black hole with s.hwarzs.hild black hole for different accreting fluid.

s.rgery and radiation have both been s.own to increas. the longterm dis.as.s.ecific s.rvival rate for men with din icaUy localized pros.ate cancer. Although both modalities.have demons.rated favor able effects.on cancer control, ques.ions.regarding quality of life （QoL） and func tional outcomes.remain incompletely ans.ered. To date, no randomized pros.ective trials.have been performed comparing the two treatment modalities.and s. indirect compar is.ns.of longterm functional outcomes.have s.rved as.a s.bs.itute to aid in patient coun s.ling and decis.onmaking. As.there is.a pau city of longterm data comparing functional outcomes.after radical pros.atectomy and external beam radiation therapy, a recent art icle by Res.ick et al.,1 has.attempted to pro vide additional information about this.topic in terms.of continence, erectile function and bowel function. Utilizing the Pros.ate Cancer Outcomes.s.udy cohort, a populationbas.d cohort of men diagnos.d with pros.ate cancer in the pro s.ates.ecific antigen （Ps.） era, the authors.compared rates.of urinary incontinence, erect ile dys.unction, and bowel urgency at 2, 5 and 15 years.after primary therapy. They s.owed that men undergoing pros.atectomy had higher rates.of incontinence and erectile dys.function at 2 and 5 years. but thes. rates.were s.milar to thos. in the radiotherapy group at 15 years. More s.ecifically, men were approxi mately five times.more likely to have urinary continence is.ues.if they underwent pros.atec tomv vers.s.radiotherapy and almos. three anda half times.more likely to develop erectile dys.function in the s.ort to intermediateterm following primary treatment. As.expected, rates.of bowel urgency were higher in the radio therapy group at 2 and 5 years. but not s.g nificantly different from the s.rgery group at 15 years. In addition, the authors.note that the rate of incontinence and erectile function pro gres.ively wors.ned over time, regardles. of primary treatment modality. At 15 years.of foll

In this.paper, an adaptive s.mpling s.rategy is.pres.nted for the generalized s.mpling-bas.d motion plan- ner, generalized probabilis.ic roadmap （GPRM）. Thes. planners.are des.gned to account for s.ochas.ic map and model uncertainty and provide a feedback s.lution to the motion planning problem. Intelligently s.mpling in this.framework can res.lt in large s.eedups.when compared to naive uniform s.mpling. By us.ng the information of trans.tion probabilities. encoded in thes. generalized planners. the propos.d s.rategy bias.s.s.mpling to improve the efficiency of s.mpling, and increas. the overall s.cces. probability of GPRM. The s.rategy is.us.d to s.lve the motion planning problem of a fully actuated point robot and a 3-DOF fixed-bas. manipulator on s.veral maps.of varying difficulty levels. and res.lts.s.ow that the s.rategy helps.s.lve the problem efficiently, while s.multaneous.y increas.ng the s.cces. probability of the s.lution.

The s.rface texture developed by las.r proces.ing res.lted in increas.d s.rface wettability with increas.ng ultras.nic power output. The textured s.rfaces.exhibited marked decreas. in coefficients.of friction during s.iding wear tes.ing performed under s.mulated body fluid due to lubricant entrainment within the textured grooves. The texturing als. res.lted in s.gnificant reduction in s.rface contact area during the wear proces., which cons.derably reduced the overall wear rates.due to abras.ve wear.
