Posttraumatische Ellenbogengelenksteife - offene Arthrolyse über dorsale Inzision („global approach“) (2004)

27 Patienten nach offener Ellenbogengelenkarthrolyse wurden im Mittel 21 Monate postoperativ (Minimum 12 Monate, Maximum 33 Monate) klinisch nachuntersucht. In allen Fällen erfolgte die Operation über eine dorsale Längsinzision mit Darstellung und primärer Schonung der Seitenbänder. Anteriore und posteriore Kapselektomien wurden bei 26 Patienten durchgeführt. Ein dynamischer gelenküberbrückender Bewegungsfixateur wurde bei 4 Patienten bei Instabilität verwendet. Das mittlere präoperative Flexionsausmaß von 109° wurde auf durchschnittlich 136° verbessert. Der Gesamtbewegungsumfang Flexion/Extension lag präoperativ bei 59° und wurde auf 112° verbessert, die Unterarmrotation lag präoperativ bei 118° und postoperativ bei 159°. Die Verbesserungen der Bewegungsausmaße waren statistisch signifikant (t < 0,005). Der präoperative Mayo Elbow Performance Score (MEPS) wurde von 60 auf 85 zum Zeitpunkt der Nachuntersuchung verbessert (p < 0,05). Alle Patienten hatten eine verbesserte Ellenbogengelenkbeweglichkeit und verminderte Schmerzen entsprechend des MEPS. An postoperativen Komplikationen traten heterotope Ossifikationen, milde symptomatische postero-laterale rotatorische Instabilität bei einem Patienten und ein Pin-Infekt auf. Keinerlei Komplikationen traten im Zusammenhang mit der dorsalen Hautinzision auf. Die dorsale Hautinzision erlaubt eine globale Darstellung der betroffenen Strukturen bei posttraumatischer Ellenbogengelenksteife. Die Arthrolyse über diesen Zugang ist erfolgversprechend und sicher. Die Armfunktion und Ellenbogengelenkbeweglichkeit können gut verbessert werden und eine Schmerzreduktion tritt ein. Die Patientenzufriedenheit dieses Eingriffes ist sehr hoch.

Image Transmission over IEEE 802.15.4 and ZigBee Networks (2005)

An image sensor network platform is developed for testing transmission of images over ZigBee networks that support multi-hopping. The ZigBee is a low rate and low power networking technology for short range communications, and it currently uses IEEE 802.15.4 MAC and PHY layers. Both ZigBee networking (NWK) and IEEE 802.15.4 MAC layer protocols are implemented on a single M16C microprocessor. Transport layer functionalities such as fragmentation and reassembly are performed at the application layer, since the ZigBee NWK does not have a fragmentation support. The multiple access scheme is CSMA/CA, therefore only the best effort multi-hop transmission of JPEG and JPEG-2000 images are tested; observations and resulting statistics are presented, and open issues are discussed.
ACTH (Acthar Gel) Reduces Toxic SOD1 Protein Linked to Amyotrophic Lateral Sclerosis in Transgenic Mice: A Novel Observation (2015)

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with a complex etiology and pathology that makes the development of new therapies difficult. ACTH has neurotrophic and myotrophic effects, but has not been tested in an ALS mouse model. The G93A-SOD1 mouse model of ALS was used to test the ability of this drug to delay ALS-like symptoms. We showed that within a specific dose range, ACTH significantly postponed the disease onset and paralysis in the mouse model. To our surprise and of greater significance is that ACTH significantly reduced the levels of soluble SOD1 in the spinal cord and CNS tissues of G93A-SOD1 treated mice as well as cultured fibroblasts.
Catalytic conversion of LPG (1986)

The low reactivity of light paraffins has long hindered their utilization as petrochemical feedstocks. Except for their use in ethylene crackers, LPG fractions have traditionally been consumed as fuel. New catalytic processes now being commercialized open new avenues for the utilization of LPG as sources of valuable petrochemical intermediates. This paper discusses processes for the dehydrogenation and aromatization of LPG.

Introduction and Motivation (2018)

The 5th generation (5G) of mobile and wireless communications is expected to have a large impact on society and industry that will go far beyond the information and communications technology (ICT) field. It is expected that 5G will play a key role for the automotive sector and transportation in general, for instance allowing for advanced forms of collaborative driving and the protection of vulnerable road users, or increased efficiency in railroad transportation. This chapter elaborates in more detail on the timing of the book with respect to the 5G developments in 3rd generation partnership project (3GPP) and global initiatives. It stresses the exact scope of the 5G system design. The chapter finally explains the approach pursued in writing this book, and introduces the structure and also presents an outline of this book.
Urocortin-II and Urocortin-III Are Cardioprotective against Ischemia Reperfusion Injury: An Essential Endogenous Cardioprotective Role for Corticotropin Releasing Factor Receptor Type 2 in the Murine Heart (2003)

Corticotropin-releasing factor (CRF) receptor type 2beta (CRFR2beta) is expressed in the heart. Urocortin (Ucn)-I activation of CRFR2beta is cardioprotective against ischemic reperfusion (I/R) injury by stimulation of the ERKs1/2 p42, 44. However, by binding CRF receptor type 1, Ucn-I can also activate the hypothalamic stress axis. Ucn-II/stresscopin related peptide and Ucn-III/stresscopin are two new members of the CRF/Ucn-I gene family and are selective for CRFR2beta. We propose that CRFR2beta selective Ucn-II or Ucn-III will protect cardiomyocytes and the ex vivo Langendorff perfused rat heart from I/R injury by activation of ERK1/2-p42, 44. Ucn-II is expressed in mouse cardiomyocytes, and Ucn-II or Ucn-III can bind to CRFR2beta, resulting in ERK1/2-p42, p-44 phosphorylation and cAMP stimulation. Phosphorylation of ERK1/2-p42, p-44 is regulated by the Ras/Raf-1 kinase pathway, independent of adenylate cyclase and, therefore, cAMP activation. Ucn-II and Ucn-III protect cardiomyocytes from I/R injury and reduce the percentage of infarct size:risk ratio in Langendorff perfused rat hearts exposed to regional I/R (P<0.001). The CRFR2 selective antagonist astressin2-B and an ERK1/2-p42, 44 inhibitor abolish the cardioprotective actions of Ucn-II and Ucn-III in reperfusion. Cardiomyocytes isolated from CRFR2-null mice are less resistant to I/R injury, compared with wild-type cardiomyocytes. We propose the use of CRFR2 selective agonists, Ucn-II and Ucn-III, to treat ischemic heart disease because of their potent cardioprotective effects in the murine heart and their minimal impact on the hypothalamic stress axis. We emphasize an important endogenous cardioprotective role for CRFR2beta in the murine heart.

Achieving comparable global accuracy in the split-step Fourier simulation of optical fiber communication channel (2005)

Optical communication system design is a challenging task because there is no general analytical solution for the nonlinear and dispersive fiber channel. Although there has been progress in analytical channel models such as Volterra series model and other variants of the perturbation model, numerical simulations are still extensively used in channel characterization, equalization and system design. In this paper, the authors are interested in finding ways to control local and global errors when the same simulation is repeated for a range of different system parameter values.
Group effects on insecticide toxicity in workers of the Formosan subterranean termite, Coptotermes formosanus Shiraki (2002)

Coptotermes formosanus workers were treated topically with insecticide and subsequently held individually or in groups to examine possible effects on insecticide toxicity. Chlorpyrifos, cypermethrin and chlordane toxicities were 1.4-, 1.5-, and 1.3-fold greater, respectively, among workers held in groups compared with those held individually after insecticide treatment. Experiments were conducted to examine how enhanced toxicity occurred among termites held in groups after topical insecticide treatment. When workers were treated topically with chlordane and immediately placed with untreated workers, significantly greater numbers of untreated workers were killed compared with controls at all ratios examined (insecticide-treated:untreated). These data indicated that workers treated topically with insecticide were capable of somehow transferring a lethal dose of insecticide to untreated workers confined in the vial. Chlordane was recovered from untreated workers which had been confined with chlordane-treated workers; significantly higher quantities of chlordane were recovered from dead workers exposed to chlordane-treated workers compared with surviving workers exposed to chlordane-treated workers. Possible mechanisms of insecticide transfer from insecticide-treated to untreated termites are discussed.
A clock network of distributed ADPLLs using an asymmetric comparison strategy (2010)

In this paper, we describe an architecture of a distributed ADPLL (All Digital Phase Lock Loop) network based on bang-bang phase detectors that are interconnected asymmetrically. It allows an automatic selection between two operating modes (uni- and bidirectional) to avoid mode-locking phenomenon, to accelerate the network convergence and to improve the robustness to possible network failures in comparison to simple unidirectional mode.
The many roles of microRNAs in brain tumor biology (2009)

MicroRNAs (miRNAs) are now recognized as the primary RNAs involved in the purposeful silencing of the cell's own message. In addition to the established role of miRNAs as developmental regulators of normal cellular function, they have recently been shown to be important players in pathological states such as cancer. The authors review the literature on the role of miRNAs in the formation and propagation of gliomas and medulloblastomas, highlighting the potential of these molecules and their inhibitors as therapeutics.
Understanding variations in circularly polarized photoluminescence in monolayer transition metal dichalcogenides (Conference Presentation) (2018)

The unique electronic band structure in monolayer transition metal dichalcogenides (TMDs) provides the ability to selectively populate a desired valley by exciting with circularly polarized light. The valley population is reflected through the circular polarization of photoluminescence (PL) and a high degree of circular polarization has been theoretically predicted for resonant excitation of TMDs such as MoS2, MoSe2, WS2 and WSe2, yet rarely observed experimentally. In fact, a wide range of values for the degree of circularly polarized emission, Pcirc, has been reported for monolayer TMDs, although the reasons for the disparity are unclear. Here we investigate the room-temperature Pcirc in TMD monolayers synthesized via chemical vapor deposition. In each material system, a wide range of Pcirc and PL intensity values are observed. However, there is a pronounced inverse correlation between Pcirc and PL intensity, which we attribute to sample-dependent variations in the exciton radiative and non-radiative lifetime components. Samples that demonstrate weak PL emission and short exciton relaxation time exhibit a high degree of valley polarization. The short exciton lifetime results in a higher measured polarization by limiting opportunity for depolarizing scattering events. These findings clarify the disparities among previously reported values and suggest a means to engineer valley polarization via controlled introduction of defects and non-radiative recombination sites.
Effects of Material Brittle/Ductile Property and Crack Tip Loading Type on Fracture Mode of a Mixed-Mode Crack. (1998)

It was shown that the fracture mode of a mixed-mode crack in a homogeneous ductile material changes from mode I (opening type) to mode II (shear type) or vice versa by changing the loading type in the neighborhood of a crack tip. The characteristics of this fracture mode change may depend not only on the loading type but also on the brittle/ductile property of a material. Thus, in the present study, the fracture experiments of the specimens with an inclined crack made up by using acryl resin and aluminum alloy are carried out under tensile and shear type loadings and it is confirmed that the different fracture modes can be realized between the specimens of above two materials even under the same loading type. Moreover, the CED in an arbitrary direction is evaluated through the finite element analyses corresponding to the experiments. Finally, it is shown that the observed fracture phenomena can be explained and the effects of brittle/ductile property of a material and loading type at the crack tip on fracture mode of a mixed mode crack can also be grasped in a unified way, by the fracture criteria based on the CED in an arbitrary direction.
RAPID: Avoiding TCP Incast Throughput Collapse in Public Clouds With Intelligent Packet Discarding (2019)

Many applications in public clouds require a high fan-in, many-to-one type of data communication (known as TCP incast) in modern Data Center Networks (DCNs). Such communication could cause severe incast congestion in switches and result in TCP throughput collapse, substantially degrading the application performance. The root cause of throughput collapse is the Retransmission Timeouts (RTO) due to packet losses in congested switches. Tenants in public clouds can opt to use a variety of TCP versions. However, the existing solutions rely on modifications of TCP protocols and specific techniques from switches, and thus these existing solutions are not always feasible for public clouds. In this paper, we are inspired by the emerging virtualization and network softwarization technologies to develop a novel scheme called Retransmission timeout Avoidance by Packet Intelligent Discarding (RAPID) using software switches. RAPID considers the number of packets of each incast flow, buffered in the switch to selectively discard some packets, and ensures that the Fast Retransmission/Fast Recovery rather than RTO is invoked at the sender(s) in response to packet loss. Thus, the long idle period of a timeout and the throughput drop are avoided. We prove that, given a predetermined minimum switch buffer space, dedicated to the incast application, RAPID can prevent RTO in all the incast senders. We also present a low-complexity heuristic version of RAPID named RAPID-ED, which combines the principles of RAPID and early detection and is extremely easy to implement on today's software switches. We evaluate the two proposed schemes in a data center network testbed built on NS-3 simulator. The simulation results confirm the theoretical expectation, and show that the RAPID and RAPID-ED perform very well to prevent RTO of TCP incast flows and hence the throughput collapse. Compared with other incast solutions, RAPID and RAPID-ED do not modify TCP protocols and therefore are more suitable in public clouds.
12.2 Micro Short-Circuit Detector Including S/H Circuit for 1hr Retention and 52dB Comparator Composed of C-Axis Aligned Crystalline IGZO FETs for Li-Ion Battery Protection IC (2019)

Li-ion batteries are primarily used as power sources in electronic devices and electric vehicles and offer substantial conveniences to consumers. However, fires have broken out likely due to micro short-circuit (also called internal or soft shortcircuit) in Li-ion batteries [1]. The micro short-circuit is a failure mode where Li metal first precipitates on a negative electrode and then reaches a positive electrode; eventually a short-circuit occurs between the negative and positive electrodes and the battery voltage slightly decreases. Repetitive occurrences of micro short-circuit will generate heat and lead to serious accidents with a fire or an explosion in the worst-case scenario. Micro short-circuit detection methods are still in the research phase, and applications of battery voltage monitoring systems with AI are expected [1], [2]. This situation demands urgent research and development of micro short-circuit detectors for battery protection ICs.
Homogenization analysis of trabecular bone and prediction of bone ingrowth using topology optimization. (1991)

Trabecular bone is a porous microstructured material which fills the metaphyses and epiphyses of long bones and also the vertebral bodies. Testing hypotheses about bone adaptation to tissue stresses or predicting the affect of microstructure on whole joint mechanics requires a microstructural analysis. The purpose of this work was to assess homogenization theory as a method of trabecular bone microstructural analysis and to predict trabecular bone adaptation around porous coated implants using a topology optimization algorithm. Chapter 2 and its appendix compared homogenization theory to other microstructural analysis methods often used to analyze trabecular bone for the analysis of both periodic and non-periodic porous materials. Homogenization theory was found to give more accurate estimates of both effective stiffness and local strain energy density than standard microstructural analysis methods. Errors in homogenization estimates of microstructural strain energy density were more significantly correlated to differences between periodic models and non-periodic materials as quantified by Fourier transform analysis than errors from other microstructural analysis methods. This result may be useful in constructing and analyzing models of trabecular bone microstructure. Chapter 3 compared homogenization predictions of apparent stiffness to experimentally measured stiffness values for 49 specimens of trabecular bone using models which matched the average specimen volume fraction and trabecular orientation. An equiaxial strut microstructure gave reasonable estimates of proximal humerus trabecular bone stiffness but did not predict the stiffness of other metaphyseal regions accurately. These results suggest that other structural features besides average bone volume fraction and trabecular orientation must be modeled to accurately predict trabecular bone stiffness and strength. Chapter 4 presented predictions of bone adaptation around an experimental canine tibial component using a topology optimization program. It was hypothesized that the processes of bone adaptation produce a structure which best resists deformation of the bone-implant composite. The results suggest the bone ingrowth and apposition are optimal in a general sense, but that physiological constraints may play a major role in determining the topology of bone structure at bone-implant interfaces.
