Hybridsysteme für die Landtechnik (2014)

In den letzten Jahren sind zahlreiche elektrisch betriebene Landmaschinen präsentiert worden. Elektrische Antriebe bieten den Vorteil der exakten Regelbarkeit, Drehzahlvariabilität und Überlastfähigkeit. Um den Vorteil einer variablen Antriebsdrehzahl zu nutzen, stehen vielfältige Möglichkeiten zur Verfügung. Dabei ist zu beachten, dass die Architektur des Antriebsstrangs die realisierbaren Funktionen maßgeblich beeinflusst. Dieser Beitrag befasst sich mit ausgewählten Hybridstrukturen und –funktionen am Beispiel eines Traktors und eines Antriebs an einem Stallmiststreuer. Des Weiteren wird über das Potenzial von elektrischen Antrieben aus Sicht österreichischer Landmaschinenhersteller berichtet.
A Destination and Mobility Path Prediction Scheme for Mobile Networks (2014)

Mobile multimedia services are gaining great momentum among subscribers of mobile networks (MNs). An understanding of the network traffic behavior is essential in the evolution of today's MNs and, thus, leads to more efficient planning and management of the network's scarce bandwidth resources. The communication efficiency can be largely improved (i.e, optimizing the allocation of the network's limited resources and sustaining a desirable quality of service) if the network anticipates the needs of its users on the move and, thus, performs reservation of radio resources at cells along the path to the destination. In this vein, we propose a mobility prediction scheme for MNs; more specifically, we first apply probability and Dempster-Shafer processes for predicting the likelihood of the next destination, for an arbitrary user in an MN, based on the user's habits (e.g, frequently visited locations). Then, at each road junction, we apply the second-order Markov chain process for predicting the likelihood of the next road segment transition, given the path from the trip origin to that specific road junction and the direction to the destination. We evaluate our proposed scheme using real-life mobility traces; the simulation results show that the proposed scheme outperforms traditional schemes.

SuperFlash® Scaling Aspects: Program Disturb (2016)

A systematic study of dominant program-disturb mechanisms in advanced embedded split-gate SuperFlash memory across ambient temperature ranging from -45°C to 175°C is presented. At low temperatures program disturb is initiated by trap-assisted band-to-band tunneling in the split-gate channel area and/or trap-assisted tunneling via thin select gate oxide and at high temperatures - by surface generation in select-gate channel. Effects of single traps on program disturb in split-gate memory have been analyzed. Good quality of thin select gate oxide and its interface with channel is important to meet stringent requirements of the wide-temperature embedded memory applications.

Numerical design of high voltage insulator structure considering SEEA charge accumulation in vacuum (2002)

A Monte Carlo simulation (MCS) method of charge accumulation based on the secondary emission electron avalanche mechanism is applied to the design of effective corrugation on an HV insulator surface. The electric field distribution on the cathode in the vicinity of a triple junction is analysed taking the charge accumulation into account. A considerable relaxation of field strength takes places due to negative charge accumulation with appropriate corrugation. The flashover voltage obtained experimentally increases as the field strength decreases. The result of MCS thus agrees well with the experimental result. This proves that the MCS method is useful for the design of high voltage insulator structures.
Designing Hierarchically Nanostructured Conductive Polymer Gels for Electrochemical Energy Storage and Conversion (2016)

Nanostructured conductive polymers have been widely researched for various applications such as energy storage and conversion, chemical/biological sensors, and biomedical devices. Recently, novel synthetic methods which adopt doping molecules as cross-linker have been developed to prepare conductive polymer gels (CPGs) with cross-linked network and 3D hierarchically porous nanostructures. The CPGs, as well as their derived carbon frameworks, exhibit high electrical conductivity, large surface area, structural tunability, and hierarchical porosity for rapid mass/charge transport, which contribute to their high performance when applied for energy storage and conversion devices. This Perspective highlights the key features of CPGs and their derived carbon frameworks, discusses their possibilities in terms of rational synthesis and energy-related applications, and proposes future directions for their technological development.
An algebraic number theoretic framework for space-time coding (2003)

In this paper, we develop a novel framework for constructing full rate, full diversity, and polynomial complexity space-time codes for systems with arbitrary numbers of transmit and receive antennas. The proposed framework combines space-time layering concepts with algebraic number theoretic constellations to construct universal codes for scenarios where the channel state information (CSI) is known a-priori at the transmitter and receiver (TR-CSI), receiver only (R-CSI), and neither one of them (N-CSI). For a coherent system (i.e., R-CSI) with M transmit and N receive antennas in quasi-static fading, the proposed codes are constructed over T = M symbol periods by properly assigning algebraic number theoretic constellations to the different layers. The proposed codes are delay-optimal and achieve the maximum diversity advantage MN over quasi-static fading channels for arbitrary numbers of antennas and arbitrary transmission rates. The lattice structure of the proposed codes allows for polynomial complexity maximum likelihood decoding using the sphere decoder. The proposed framework subsumes many of the existing codes in the literature, extends naturally to time-selective and frequency-selective channels, and allows for more flexibility in the trade-off between power efficiency, bandwidth efficiency, and receiver complexity.
Ultra-broadband and high response of the Bi<sub>2</sub>Te<sub>3</sub>–Si heterojunction and its application as a photodetector at room temperature in harsh working environments (2015)

Broadband photodetection is central to various technological applications including imaging, sensing and optical communications. On account of their Dirac-like surface state, Topological insulators (TIs) are theoretically predicted to be promising candidate materials for broadband photodetection from the infrared to the terahertz. Here, we report a vertically-constructed ultra-broadband photodetector based on a TI Bi2Te3-Si heterostructure. The device demonstrated room-temperature photodetection from the ultraviolet (370.6 nm) to terahertz (118 μm) with good reproducibility. Under bias conditions, the visible responsivity reaches ca. 1 A W(-1) and the response time is better than 100 ms. As a self-powered photodetector, it exhibits extremely high photosensitivity approaching 7.5 × 10(5) cm(2) W(-1), and decent detectivity as high as 2.5 × 10(11) cm Hz(1/2) W(-1). In addition, such a prototype device without any encapsulation suffers no obvious degradation after long-time exposure to air, high-energy UV illumination and acidic treatment. In summary, we demonstrate that TI-based heterostructures hold great promise for addressing the long lasting predicament of stable room-temperature high-performance broadband photodetectors.
Selection of adjuvants for vaccines targeting specific pathogens (2019)

Adjuvants form an integral component in most of the inactivated and subunit vaccine formulations. Careful and proper selection of adjuvants helps in promoting appropriate immune responses against target pathogens at both innate and adaptive levels such that protective immunity can be elicited. Areas covered: Herein, we describe the recent progress in our understanding of the mode of action of adjuvants that are licensed for use in human vaccines or in clinical or pre-clinical stages at both innate and adaptive levels. Different pathogens have distinct characteristics, which require the host to mount an appropriate immune response against them. Adjuvants can be selected to elicit a tailor-made immune response to specific pathogens based on their unique properties. Identification of biomarkers of adjuvanticity for several candidate vaccines using omics-based technologies can unravel the mechanism of action of modern and experimental adjuvants. Expert opinion: Adjuvant technology has been revolutionized over the last two decades. In-depth understanding of the role of adjuvants in activating the innate immune system, combined with systems vaccinology approaches, have led to the development of next-generation, novel adjuvants that can be used in vaccines against challenging pathogens and in specific target populations.
Distributed routing for load balancing (1989)

Some open-loop and closed-loop control algorithms are discussed for an example of a discrete-event system, namely, the routing of arriving tasks from different arrival streams among several possible service stations. It is shown that it is possible to design open-loop policies that give good performance in a way which is very robust with respect to large changes in the arrival rates. This is possible even though it is assumed that there is no online coordination between the routing algorithms for the different arrival streams. Some further improvements of the performance are possible when a simple feedback policy, namely, overflow routing, is implemented. This also gives reasonable robustness of performance with respect to changes in the service rates.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Requirements for selective recruitment of Ets proteins and activation of mb-1/Ig-  gene transcription by Pax-5 (BSAP) (2003)

Pax-5, a member of the paired domain family of transcription factors, is a key regulator of B lymphocyte-specific transcription and differentiation. A major target of Pax-5-mediated activation is the mb-1 gene, which encodes the essential transmembrane signaling protein Ig-alpha. Pax-5 recruits three members of the Ets family of transcription factors: Ets-1, Fli-1 and GABPalpha (with GABPbeta1), to assemble ternary complexes on the mb-1 promoter in vitro. Using the Pax-5:Ets-1:DNA crystal structure as a guide, we defined amino acid requirements for transcriptional activation of endogenous mb-1 genes using a novel cell-based assay. Mutations in the beta-hairpin/beta-turn of the DNA-binding domain of Pax-5 demonstrated its importance for DNA sequence recognition and activation of mb-1 transcription. Mutations of amino acids contacting Ets-1 in the crystal structure reduced or blocked mb-1 promoter activation. One of these mutations, Q22A, resulted in greatly reduced mb-1 gene transcript levels, concurrent with the loss of its ability to recruit Fli-1 to bind the promoter in vitro. In contrast, the mutation had no effect on recruitment of the related Ets protein GABPalpha (with GABPbeta1). These data further define requirements for Pax-5 function in vivo and reveal the complexity of interactions required for cooperative partnerships between transcription factors.
Hybrid mechanisms: Towards an efficient wireless sensor network medium access control (2011)

In recent years, there has been growing interest in understanding and improving wireless sensor network (WSN) medium access control (MAC) because of the limited and constrained nature of WSNs. By controlling the access to the channel, MAC plays an important role in determining channel capacity utilization, network delay and power consumption and it affects congestion and fairness in channel usage. The MAC mechanisms are mainly classified into contention, schedule and hybrid. A hybrid mechanism combines the strengths of the last two. The main feature of the hybrid MAC mechanism is its adaptability to the level of contention in the network. This paper focuses on the trends in the development of hybrid mechanisms and presents comparative results of hybrid mechanisms with CSMA (Carrier Sense Multiple Access) and TDMA (Time Division Multiple Access) based MAC. Simulation results show that the performance of the hybrid mechanism is better in varying traffic and area of network. Finally, the paper proposes and discusses the requirements to design future energy efficient hybrid MAC.
Spatiotemporal distribution of heparan sulfate epitopes during myogenesis and synaptogenesis: A study in developing mouse intercostal muscle (2002)

Formation of a basal lamina (BL) ensheathing developing skeletal muscle cells is one of the earliest events in mammalian skeletal muscle myogenesis. BL-resident heparan sulfate proteoglycans have been implicated in various processes during myogenesis, including synaptic differentiation. However, attention has focused on the proteoglycan protein core, ignoring the glycosaminoglycan moiety mainly because of a lack of appropriate tools. Recently, we selected a panel of anti-heparan sulfate antibodies applied here to study the spatiotemporal distribution of specific heparan sulfate (HS) epitopes during myogenesis. In mouse intercostal muscle at embryonic day (E14), formation of acetylcholine receptor clusters at synaptic sites coincides with HS deposition. Although some HS epitopes show a general appearance throughout the BL, one epitope preferably clusters at synaptic sites but does so only from E16 onward. During elongation and maturation of primary myotubes, a process preceding secondary myotube development, significant changes in the HS epitope constitution of both synaptic and extrasynaptic BL were observed. As a whole, the data presented here strengthen previous observations on developmental regulation by BL components, and add to the putative roles of specific HS epitopes in myogenesis and synaptogenesis.
Linkage disequilibrium between the juvenile neuronal ceroid lipofuscinosis gene and marker loci on chromosome 16p 12.1. (1994)

The neuronal ceroid lipofuscinoses (NCL; Batten disease) are a collection of autosomal recessive disorders characterized by the accumulation of autofluorescent lipopigments in the neurons and other cell types. Clinically, these disorders are characterized by progressive encephalopathy, loss of vision, and seizures. CLN3, the gene responsible for juvenile NCL, has been mapped to a 15-cM region flanked by the marker loci D16S148 and D16S150 on human chromosome 16. CLN2, the gene causing the late-infantile form of NCL (LNCL), is not yet mapped. We have used highly informative dinucleotide repeat markers mapping between D16S148 and D16S150 to refine the localization of CLN3 and to test for linkage to CLN2. We find significant linkage disequilibrium between CLN3 and the dinucleotide repeat marker loci D16S288 (chi 2(7) = 46.5, P < .005), D16S298 (chi 2(6) = 36.6, P < .005), and D16S299 (chi 2(7) = 73.8, P < .005), and also a novel RFLP marker at the D16S272 locus (chi 2(1) = 5.7, P = .02). These markers all map to 16p12.1. The D16S298/D16S299 haplotype "5/4" is highly overrepresented, accounting for 54% of CLN3 chromosomes as compared with 8% of control chromosomes (chi 2 = 117, df = 1, P < .001). Examination of the haplotypes suggests that the CLN3 locus can be narrowed to the region immediately surrounding these markers in 16p12.1. Analysis of D16S299 in our LNCL pedigrees supports our previous finding that CLN3 and CLN2 are different genetic loci. This study also indicates that dinucleotide repeat markers play a valuable role in disequilibrium studies.
Effect of periodic strain on the leaky modes in single-mode fiber (1988)

The effect of periodic strain on the beat wavelength between the guided LP(01) and the leaky LP(11) modes is approximated around the LP(11) mode cutoff. An abrupt change of the beat wavelength as a function of optical wavelength signifies the onset of the cutoff region. An order parameter is suggested to characterize the transition of the LP(11) mode from a guided to a cladding mode.
Classifying RFID attacks and defenses (2009)

RFID (Radio Frequency Identification) systems are one of the most pervasive computing technologies with technical potential and profitable opportunities in a diverse area of applications. Among their advantages is included their low cost and their broad applicability. However, they also present a number of inherent vulnerabilities. This paper develops a structural methodology for risks that RFID networks face by developing a classification of RFID attacks, presenting their important features, and discussing possible countermeasures. The goal of the paper is to categorize the existing weaknesses of RFID communication so that a better understanding of RFID attacks can be achieved and subsequently more efficient and effective algorithms, techniques and procedures to combat these attacks may be developed.
Persistent symptoms in mild to moderate traumatic brain injury associated with executive dysfunction (2010)

In order to improve detection of subtle cognitive dysfunction and to shed light on the etiology of persistent symptoms after mild-to-moderate traumatic brain injury (TBI), we employed an experimental executive reaction time (RT) test, standardized neuropsychological tests, and diffusion tensor imaging (DTI). The Executive RT-Test, an Executive Composite Score from standardized neuropsychological tests, and DTI-indices in the midbrain differentiated between patients with persistent symptoms from those fully recovered after mild-to-moderate TBI. We suggest that persistent symptoms in mild-to-moderate TBI may reflect disrupted fronto-striatal network involved in executive functioning, and the Executive RT-Test provides an objective and novel method to detect it.
A CMOS image sensor employing a double junction photo-diode (2001)

A CMOS image sensor that employs a vertically integrated double junction photodiode structure is presented. This allows colour imaging with only two, wider bandwidth, filters. The sensor uses a 184 x 154 6-transistor pixel array at a 9.6 μm pitch. Results of the device characterisation, and colour image reconstruction using the prototype sensor, are presented.
Active and reactive current decoupled control strategy applied to a single-phase BTB converter (2009)

This paper presents a comparison of two control strategies applied to a Single-Phase Back to Back converter. Both techniques use two loops: one inner current loop and an outer voltage loop. The first control strategy is based on a classical PI control. The second one uses a control scheme to decouple the active and reactive component of the input current, obtaining a better steady state and dynamic response of the system. The performance is verified with simulation and experimental results.
