PERIPROSTHETIC FEMORAL FRACTURES AROUND WELL-FIXED IMPLANTS (2002)

Background: Periprosthetic femoral fractures around hip replacements are increasingly common. When the femoral component is stable, open reduction and internal fixation is recommended in all but exceptional cases. The purpose of this study was to evaluate the outcome of treatment of fractures around stable implants with cortical onlay strut allografts with or without a plate. Methods: A survey of our four centers identified forty patients with a fracture around a well-fixed femoral stem treated with cortical onlay strut allografts without revision of the femoral component. There were fourteen men and twenty-six women, with an average age of sixty-nine years. Nineteen patients were treated with cortical onlay strut allografts alone, and twenty-one were managed with a plate and one or two cortical struts. All of the patients were followed until fracture union or until a reoperation was done. The mean duration of follow-up was twenty-eight months for thirty-nine patients. One patient, who was noncompliant with treatment recommendations, had a failure at two months because of a fracture of the plate and graft. The primary end point of the evaluation was fracture union; secondary end points included strut-to-host bone union, the amount of final bone stock, and postoperative function. Results: Thirty-nine (98%) of the forty fractures united, and strut-to-host bone union was typically seen within the first year. There were four malunions, all of which had <10° of malalignment, and one deep infection. There was no evidence of femoral loosening in any patient. All but one of the surviving patients returned to their preoperative functional level within one year. Conclusions: Cortical onlay strut allografts act as biological bone plates, serving both a mechanical and a biological function. The use of cortical struts, either alone or in conjunction with a plate, led to a very high rate of fracture union, satisfactory alignment, and an increase in femoral bone stock at the time of short-term follow-up. Although this study did not address the potential for later allograft remodeling, our findings suggest that cortical strut grafts should be used routinely to augment fixation and healing of a periprosthetic femoral fracture.

An algorithm and review of blepharoplasty and canthopexy (2010)

The upper third of the face, anchored by the eyes, is an important cosmetic unit. While there are several noninvasive procedures that can rejuvenate this region, upper and lower blepharoplasties are still the cornerstones. By eliminating redundant skin and puffiness, the upper blepharoplasty creates more eyelid show and makes the eyes appear more prominent. The lower blepharoplasty, by conservatively removing or repositioning fat, will reduce bags and create a smooth transition between the lower eyelid and upper cheek. Simultaneous resurfacing of the lower eyelids will diminish periorbital rhytides and tighten skin after fat removal. Adjunct procedures, such as canthoplasty or the less invasive canthopexy, will decrease the risk of ectropion in those patients with pre-existing lid laxity.
Continuity preserving modified maximum cross‐correlation technique (2002)

The maximum cross‐correlation (MCC) method reconstructs the surface advective velocity fields from the displacements of spatial patterns in pairs of sequential satellite (normally infrared) images. However, the performance of the conventional MCC method is not always satisfactory. One of the main reasons for this is the fact that the method can correctly estimate only the velocity component parallel to the gradient of the property depicted in the images, while any small displacement perpendicular to the gradient (i.e., directed along the isolines) essentially maps the spatial pattern onto itself and therefore can not be detected using the conventional MCC technique. In the present work we propose a modification of the MCC method that allows circumventing this basic deficiency and improving the performance of the MCC technique. In this approach, the “cross‐isoline” components of the velocity field are obtained as in the conventional MCC scheme; however, the “along‐isoline” components derived from the MCC are disregarded as unreliable. Instead, the “true” along‐isoline components are then reconstructed from the given cross‐isoline velocity field based on the continuity requirement and on the condition of no normal flow at solid boundaries. This inverse problem is solved by constructing the two‐dimensional stream function in the curvilinear coordinate frame associated with the image isolines. The method is illustrated using AVHRR images from the southwestern Atlantic Ocean and the Black Sea. The results are compared with some direct drifter and current meter measurements and geostrophic estimates.
Examining Predictors and Outcomes of Identity Communication in Virtual Teams (2015)

Virtual teams play an increasingly important role in the modern economy, and many organizations struggle to overcome the weaknesses inherent in technology-mediated work. Identity communication has been shown to greatly improve individual- and group-level outcomes in offline settings, but these benefits have not been investigated in the context of virtual teams, where mediated interaction can affect the opportunity for identity communication. This research-in-progress paper proposes a theoretical model and experimental design that investigates the predictors and outcomes of identity communication in virtual teams. Our anticipated findings should have important implications for researchers seeking to understand identity communication via technology and for practitioners hoping to improve virtual team communication and collaboration. \\

Material Storage Mechanism in Porous Nanocarbon (2004)

Material storage in the inner spaces of nanocarbon materials is visualized for the first time. It is shown that creating paths of a specific size to the inner space (see Figure) is indispensable for material storage in carbon nanopores, and that the adsorption rate for fullerene molecules is largely dependent on the nanoscale curvature of the graphitic planes composing the nanospaces.

Materialanalyse von elektroerosiv geschädigten Kontaktwerkstoffen im Niederspannungsbereich (2013)

Die von einem elektrischen Lichtbogen verursachten Werkstoffschädigungen treten in zahlreichen technisch relevanten Applikationen auf. Vor allem die Lebensdauer und die Eigenschaften der betroffenen Komponenten werden dadurch negativ beeinflusst. Das Wissen über die Wechselwirkung zwischen Werkstoff und Lichtbogen für ein besseres Verständnis und eine Weiterentwicklung der Werkstoffe ist daher von großer Bedeutung.\nZiel dieser Arbeit ist es, einen Beitrag zum grundsätzlichen Verständnis dieser Wechselwirkung zu leisten. Dies geschieht anhand zweier technisch relevanter Beispiele. Einerseits wurden grundlegende Untersuchungen am Kontaktmaterial Silber/Zinnoxid (Ag/SnO2) durchgeführt, andererseits ist die Schädigung an Titanwerkstoffen in korrosiven Medien analysiert worden.\nFür den Werkstoff Ag/SnO2 ist ein Modellschalter konzipiert worden um unterschiedliche Parameter konstant einzustellen. Anschließend sind die Gefügemodifikationen und morphologischen Änderungen an den Elektroden unter verschiedenen Aspekten interpretiert worden. Im Anschluss sind die Gefüge mittels Tomographie rekonstruiert und für Simulationen der elektrischen Leitfähigkeit genutzt worden.

Particle growth in butadiene emulsion polymerization, 1. The use of Fremy salt as aqueous radical scavenger (1994)

Abstract The kinetics of the seeded emulsion polymerization of butadiene in combination with variable Fremy salt (potassium nitrosodisulfonate) concentrations was investigated in order to monitor non‐steady state kinetics necessary for obtaining information on entry and exit of radicals from latex particles. Fremy salt is used because it is an entirely water‐soluble stable radical that in principle can scavenge water‐soluble radicals produced by a water‐soluble initiator like peroxodisulfate, but allegedly will not interfere with radicals within latex particles. Adequate buffering of the pH is a prerequisite for stable Fremy salt concentrations in time. Emulsion polymerizations in the presence of Fremy salt showed that not all radicals in the aqueous phase of a swollen polybutadiene latex are scavenged. The use of Fremy salt to monitor non‐steady state kinetics in the seeded emulsion polymerization of butadiene in the presence of tertiary dodecyl mercaptan yields no satisfying results. The use of Fremy salt seems to be restricted to systems where the rate of polymerization is strongly influenced by variation in initiator concentration, i.e. the styrene system or the butadiene system in the absence of tertiary dodecyl mercaptan.
Tutorial II: The green Internet of Things (2015)

Every day, we hear about the Internet of Things (IoT) and how it is in the process of revolutionizing machine-to-machine (M2M) interaction, allowing a myriad of connected devices to interact and co-operate in order to make our lives richer. In this tutorial, we will explain and illustrate, through theoretical examples, simulations and real-world proof-of-concept experiments, why a true Smart Grid would require an IoT-like, distributed "nervous system" comprised of sensors, relays and actuators to function properly and break the scalability barrier. In particular, we will demonstrate how such a system could play a key part in making renewable sources easier to integrate in the overall energy mix by balancing supply and demand in a much finer and responsive way than is possible today, thereby reducing the average carbon footprint of power generation and making a direct contribution to a more sustainable society.

Experimental and numerical study of a split cathode fed relativistic magnetron (2021)

The relativistic magnetron is one of the most efficient high power microwave (HPM) sources but pulse shortening, the result of explosive cathode plasma's radial expansion toward the anode, makes it impractical because the HPM pulse terminates much earlier than the applied voltage. We present experimental results of the operation of a relativistic magnetron fed by a split cathode. A split cathode [Leopold et al., Phys. Plasmas 27, 103102 (2020)] consists of a cathode placed upstream and outside the anode, connected by an axial rod to a reflector (a transverse conducting circular plate) placed downstream from the anode. The electron charge, emitted by an annular explosive cathode emitter, accumulates in the space between the cathode and the reflector and at the same time, screens the rod from explosive plasma formation. This accumulated space charge serves as the electron source for the magnetron. The explosive plasma developing on the emitter remains outside the magnetron and does not propagate into the anode while it operates. We compare the performance of the magnetron operating with a standard explosive emitting solid carbon cathode to that with a split cathode. The experiments demonstrate that whereas for the solid cathode, the microwave pulse developing in the magnetron suffers from pulse shortening, with a split cathode, the pulse survives as long as the amplitude of the applied voltage is sufficient for the magnetron's operation. We support the experiment by particle-in-cell simulations.
Man-portable Vector Time Domain EMI Sensor and Discrimination Processing (2012)

Abstract : SERDP project MR-1443 entitled Man-portable Vector Time Domain EMI Sensor and Discrimination Processing is complete. This report contains the final design, engineering challenges, modeling advancements, and data analysis results from this project. This combination of vector receivers coupled with a laser positioning system resulted in a versatile prototype instrument delivering high quality, diverse data well suited to rigorous models of UXO and soil. New algorithms aimed at utilizing the high quality data from the MPV were developed including the Generalized Standardized Excitations Approach (GSEA) and Normalized Surface Magnetic Source (NSMS). Results from this project suggest a further need for high quality, hand held, production instruments in the time domain suited to UXO remediation efforts. The MPV2 instrument incorporates a redesign of the MPV concept.
Environmental determinants of diving beetle assemblages (Coleoptera: Dytiscidae) in an urban landscape (2020)

Abstract Blue infrastructure is an important component of urban green infrastructure, due to its capacity for water cycle regulation and soil formation, as well as supporting unique biodiversity. Urban ponds, as part of urban blue, can harbour a diverse assemblage of aquatic macroinvertebrates. As yet, it is not clear how urbanisation affects macroinvertebrate diversity. In this study, we focus on diving beetles (Dytiscidae) in the Helsinki Metropolitan Area, Finland, to investigate how urbanisation affects their diversity, as well as the effects of margin steepness and the presence or absence of fish on urban dytiscids. We sampled dytiscids using 1-L activity traps in 14 fishless ponds and 11 ponds with fish, at ten sites. We applied generalised linear mixed models (GLMM) and non-metric multidimensional scaling (NMDS) to analyse the effects on dytiscid assemblages. We found that urbanisation had a negative effect on species richness but not on abundance. Steepness of pond margins and the presence or absence of predatory fish, affected both species richness and abundance: dytiscids prefer ponds with gently sloping margins; they have 80% higher species richness and are 79% more abundant in fishless ponds, and medium to large-sized dytiscid species are more capable of coexisting with fish. Urban wetlands can support a diversity of dytiscids at the regional level, and the presence of ponds without predatory fish is beneficial for maintaining dytiscid diversity. We recommend maintaining a diverse range of ponds and wetland habitats for the maintenance of aquatic biodiversity in urban regions.
Comparison of RT-dPCR and RT-qPCR and the effects of freeze–thaw cycle and glycine release buffer for wastewater SARS-CoV-2 analysis (2022)

Public health efforts to control the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic rely on accurate information on the spread of the disease in the community. Acute and surveillance testing has been primarily used to characterize the extent of the disease. However, obtaining a representative sample of the human population is challenging because of limited testing capacity and incomplete testing compliance. Wastewater-based epidemiology is an agnostic alternative to surveillance testing that provides an average sample from the population served by the treatment facility. We compare the performance of reverse transcription quantitative PCR (RT-qPCR) and reverse transcription digital droplet PCR (RT-dPCR) for analysis of SARS-CoV-2 RNA in a regional wastewater treatment facility in northern Indiana, USA from the earliest stages of the pandemic. 1-L grab samples of wastewater were clarified and concentrated. Nucleic acids were extracted from aliquots and analyzed in parallel using the two methods. Synthetic viral nucleic acids were used for method development and generation of add-in standard-curves. Both methods were highly sensitive in detecting SARS-CoV-2 in wastewater, with detection limits as low as 1 copy per 500 mL wastewater. RT-qPCR and RT-dPCR provided essentially identical coefficients of variation (s/[Formula: see text] = 0.15) for triplicate measurements made on wastewater samples taken on 16 days. We also observed a sevenfold decrease in viral load from a grab sample that was frozen at - 80 °C for 92 days compared to results obtained without freezing. Freezing samples before analysis should be discouraged. Finally, we found that treatment with a glycine release buffer resulted in a fourfold inhibition in RT-qPCR signal; treatment with a glycine release buffer also should be discouraged. Despite their prevalence and convenience in wastewater analysis, glycine release and freezing samples severely and additively (~ tenfold) degraded recovery and detection of SARS-CoV-2.
Overexpression of Human CRB1 or Related Isoforms, CRB2 and CRB3, Does Not Regulate the Human Presenilin Complex in Culture Cells (2007)

The presenilin proteins (PS1 and PS2) with their partners (NCT, Aph1, and Pen2) are the major components of the high molecular weight gamma-secretase complex which facilitates the intramembraneous cleavage of various type 1 transmembrane proteins, including the amyloid-beta precursor protein (APP) and the Notch receptor. Additional gamma-secretase complex components may be involved in regulation of its activity and specificity. A recent investigation indicated that the Crumbs protein is a negative regulator of Notch signaling and may act by repressing gamma/epsilon-secretase activity in Drosophila [Herranz, H., Stamataki, E., Feiguin, F., and Milan, M. (2006) EMBO Rep. 7, 297-302]. To address this question, we investigated potential functional interactions between the human Crumbs homologues (CRB1, CRB2, and CRB3) and presenilin complexes which mediate gamma/epsilon-secretase cleavage of APP and Notch. We found no evidence for direct interaction between CRB1, CRB2, or CRB3 and presenilin complex components. Furthermore, overexpression of human CRB1 and related isoforms, CRB2 and CRB3, had no effect on the levels of presenilin complex components, on NCT maturation or on PS endoproteolysis, and did not alter Abeta AICD or NICD production. These results suggest that, in mammalian cells at least, Crumbs is unlikely to be a significant direct modulator of presenilin-dependent gamma/epsilon-secretase activity.
Controlling Scratching in Cu Chemical Mechanical Planarization (2009)

In the manufacture of advanced semiconductor devices, undesirable scratches are produced during such fine-scale material removal processes as chemical mechanical planarization (CMP). In this paper, the upper bound loads for scratching in CMP at single-particle contacts are estimated and validated by atomic force microscope experiments on thin, homogeneous coatings. The upper limits for the scratch width and depth are estimated and validated by polishing experiments. For a Cu surface polished on a Rohm and Haas IC1000 pad with or abrasives, the maximum scratch width is about one-half of the abrasive particle diameter.
The effect of acute experimental retinal vein occlusion on cat retinal vein pressures. (1997)

In retinal vein occlusion, venous pressures in a segmental retinal circulatory bed are not substantially elevated, thus implying the presence of a pressure-release mechanism and implicating vascular damage for the increased transvascular fluid flux. The lack of vascular collapse downstream of the occlusion site suggests collateral communication before a large intraocular pressure-dependent resistance segment that lies between the intraocular and extraocular vessels.
