Discrete-element-method （DEm） simulations have been performed to investigate the cross-sectional flow of non-spherical particles in horizontal rotating cylinders with and without wall rougheners. The non-spherical particles were modeled using the three-dimensional super-quadric equation. The influence of wall rougheners on flow behavior of grains was studied for increasing particle blockiness. moreover, for approximately cubic particles （squareness parameters [555]）, the rotational speed, gravitational acceleration and particle size were altered to investigate the effect of wall rougheners under a range of operating conditions. For spherical and near-spherical particles （approximately up to the squareness parameters [344]）, wall rougheners are necessary to prevent slippage of the bed against the cylinder wall. For highly cubic particle geometries （squareness parameters larger than [3441）, wall rougheners resulted in a counter-intuitive decrease in the angle of repose of the bed. In addition, wall rougheners employed in this study were demonstrated to have a higher impact on bed dynamics at higher rotational speeds and lower gravitational accelerations. Nevertheless, using wall rougheners had a comparatively small influence on particle-flow characteristics for a bed composed of finer grains.

Listeria monocytogenes （Lm） is an intracellular bacterium with unique predisposition for systemic maternal infection during pregnancy and morbid consequences for the developing fetus. Given the high mortality associated with prenatal Lm infection, strategies for augmenting protective immunity during the exceedingly vulnerable period of pregnancy are urgently needed. Herein, protection conferred by attenuated Lm administered before pregnancy against subsequent virulent Lm prenatal infection was evaluated. We show that protection against secondary Lm infection in non-pregnant mice is sharply moderated during allogeneic pregnancy because significantly more bacteria are recovered from maternal tissues, despite the numerical and functional preservation of pathogen-specific CD8^＋ T cells. more importantly, preconceptual priming does not protect against in utero invasion or fetal wastage because mice inoculated with attenuated Lm prior to pregnancy and naive pregnant controls each showed near complete fetal resorption and pathogen recovery from individual concepti after Lm infection during pregnancy. Remarkably, the lack of protection against prenatal Lm infection with preconceptual priming in allogeneic pregnancy is restored during syngeneic pregnancy. Thus, maternal-fetal antigen discordance dictates the ineffectiveness of preconceptual vaccination against fetal complications after prenatal Lm infection, despite the numerical and functional preservation of pathogen-snecific CD8^＋ T cells.

surgery and radiation have both been shown to increase the longterm diseasespecific survival rate for men with din icaUy localized prostate cancer. Although both modalities have demonstrated favor able effects on cancer control, questions regarding quality of life （QoL） and func tional outcomes remain incompletely answered. To date, no randomized prospective trials have been performed comparing the two treatment modalities and so indirect compar isons of longterm functional outcomes have served as a substitute to aid in patient coun seling and decisionmaking. As there is a pau city of longterm data comparing functional outcomes after radical prostatectomy and external beam radiation therapy, a recent art icle by Resnick et al.,1 has attempted to pro vide additional information about this topic in terms of continence, erectile function and bowel function. Utilizing the Prostate Cancer Outcomes Study cohort, a populationbased cohort of men diagnosed with prostate cancer in the pro statespecific antigen （PSA） era, the authors compared rates of urinary incontinence, erect ile dysfunction, and bowel urgency at 2, 5 and 15 years after primary therapy. They showed that men undergoing prostatectomy had higher rates of incontinence and erectile dys function at 2 and 5 years, but these rates were similar to those in the radiotherapy group at 15 years. more specifically, men were approxi mately five times more likely to have urinary continence issues if they underwent prostatec tomv versus radiotherapy and almost three anda half times more likely to develop erectile dys function in the short 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 sig nificantly different from the surgery group at 15 years. In addition, the authors note that the rate of incontinence and erectile function pro gressively worsened over time, regardless of primary treatment modality. At 15 years of foll
