description: Let [θ] denote the integer part and θ the fractional part of the real number θ. For θ> 1 and {θ^{1/n}} \neq 0, define M_θ(n) = [1/{θ^{1/n}}]. The arithmetic function M_θ(n) is eventually increasing, and \lim_{n\rightarrow \infty} M_θ(n)/n = 1/\log θ. Moreover, M_θ(n) is "linearly periodic" if and only if \log θis rational. Other results and problems concerning the function M_θ(n) are discussed.

description: We introduce a "renormalized entanglement entropy" which is intrinsically UV finite and is most sensitive to the degrees of freedom at the scale of the size R of the entangled region. We illustrated the power of this construction by showing that the qualitative behavior of the entanglement entropy for a non-Fermi liquid can be obtained by simple dimensional analysis. We argue that the functional dependence of the "renormalized entanglement entropy" on R can be interpreted as describing the renormalization group flow of the entanglement entropy with distance scale. The corresponding quantity for a spherical region in the vacuum, has some particularly interesting properties. For a conformal field theory, it reduces to the previously proposed central charge in all dimensions, and for a general quantum field theory, it interpolates between the central charges of the UV and IR fixed points as R is varied from zero to infinity. We conjecture that in three (spacetime) dimensions, it is always non-negative and monotonic, and provides a measure of the number of degrees of freedom of a system at scale R. In four dimensions, however, we find examples in which it is neither monotonic nor non-negative.

description: Postoperative Schmerzen sowie postoperative Übelkeit und Erbrechen (PONV) zählen zu den problematischsten Erfahrungen in Zusammenhang mit Operationen. Bei der Trichterbrust-Operation nach Donald Nuss sind die postoperativen Schmerzen meist besonders ausgeprägt und erfordern ein gutes anästhesiologisches und interdisziplinäres Management. In der vorliegenden Arbeit galt es herauszufinden inwieweit die intraoperative Opioidgabe die postoperativen Schmerzen und die postoperative Beatmungsdauer beeinflusst. Eine weitere Fragestellung betraf die patienten-kontrollierten Analgesie (PCA) zur postoperativen Schmerztherapie und ob diese eine gute Alternative zur Periduralanalgesie darstellt. Insgesamt wurden in die prospektive Longitudinalstudie vom 76 Patienten eingeschlossen und im postoperativen Verlauf beobachtet. Anhand der Ergebnisse konnte gezeigt werden, dass die intraoperative Opioidgabe keinen signifikanten Einfluss auf die postoperativen Schmerzen und die Beatmungsdauer hat. Die patienten-kontrollierte Analgesie (PCA) erwies sich als risikoarme und gute Alternative zur Periduralanalgesie.

description: AlGaN/GaN high electron mobility
transistors (HEMTS on SiC) were characterized before and
after SiO2/Si3N4 passivation. DC, small signal, pulsed and
large signal measurements were performed. We discuss the
role and the influence of passivation on the device
performance and characteristics. A good correlation is
observed between pulsed and power measurements. At
10GHz, a 6.3W/mm power density with a 36% PAE at 2dB
of compression was obtained after passivation, while only
2.9W/mm before passivation.

description: A broadband amplifier for high-bitrate
transmission is presented, using a standard GaAs-HBT process
with fT and fmax of 36 and 170 GHz, respectively, at the
operating bias point. The design takes optimum advantage of
the available technology, reaching 75% of fT, a record value
for GaAs HBT. Well-opened output eye diagrams at 20 and 40
Gbps are obtained with 1.4 Vpp and 1.2 Vpp, respectively, as
well as a 4 Vpp output swing at 20 Gbps for 1.7 Vpp input

description: Pickering emulsion stabilized by Fe3O4 nanoparticles and ferrocene derivates via the self-assembly route exhibited good stability and the stability can be modulated by redox and applying magnetic field. The Fe3O4 nanoparticles modified by oxided ferrocene derivates (Fc+H) were used as emulsifier to prepare Pickering emulsions. The structure and properties of the emulsifier particles and emulsions were characterized by contact angle analyzer, Zeta potential meter, Fourier transform infrared spectrometer, X-ray diffraction analyzer and polarizing microscope. It was found that the conditions for obtaining stable emulsions were 41.0% molar percentage of Fc+H modified Fe3O4 nanoparticles. Moreover, the stability of emulsions can be modulated by redox and magnetic fields.

description: A 5 watt wideband power amplifier using a SiC
MESFET has been designed. The frequency range covers
10 MHz to 2.4 GHz with small-signal gain of 8 dB. A
broadband choke structure with a new technique was
developed to obtain good isolation and low loss over the
desired bandwidth. Input and output matching networks and
shunt feedback topology were introduced to increase the
bandwidth. At VDS= 30 V and IDS = 500 mA, power
performance measurements with PAE of almost 35%, an
output power of ≥ 37 dBm and 8 dB power gain over the
operating bandwidth were achieved. Two-tone measurements
at frequency spacing of 200 kHz were also done and OIP2 and
OIP3 of 76 dBm and 49 dBm, respectively, were obtained.
Finally, AM/AM and AM/PM distortions were measured and
the results are discussed.
Multi-channel Hybrid Access Femtocells: A Stochastic Geometric Analysis

Publisher: name: arXiv
Year: 2011
Subjects: subject: Networking and Internet Architecture (cs.NI)
subject: FOS: Computer and information sciences

description: For two-tier networks consisting of macrocells and femtocells, the channel access mechanism can be configured to be open access, closed access, or hybrid access. Hybrid access arises as a compromise between open and closed access mechanisms, in which a fraction of available spectrum resource is shared to nonsubscribers while the remaining reserved for subscribers. This paper focuses on a hybrid access mechanism for multi-channel femtocells which employ orthogonal spectrum access schemes. Considering a randomized channel assignment strategy, we analyze the performance in the downlink. Using stochastic geometry as technical tools, we model the distribution of femtocells as Poisson point process or Neyman-Scott cluster process and derive the distributions of signal-to-interference-plus-noise ratios, and mean achievable rates, of both nonsubscribers and subscribers. The established expressions are amenable to numerical evaluation, and shed key insights into the performance tradeoff between subscribers and nonsubscribers. The analytical results are corroborated by numerical simulations.

description: The advantage of planar technology for the
AlGaN/GaN HEMTs realization is demonstrated in this
paper. A breakdown voltage closed to 100 V and an output
power density of 4 W/mm at 4 GHz have been measured on
a 2x25x1.5 µm² HEMT on sapphire substrate. These results
are very promising because the devices have not been
passivated, and no T gate has been achieved. Moreover,
planar technology offers the advantage of a better
reliability. At present time, it is the best power result
obtained with an isolation by argon implantation.
An Array-Based Design Methodology for
10 GHz SiGe LC Oscillators
Creators: name: Smith, P.

Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2004
Subjects: ING-INF/01 Elettronica

description: In this paper, a mask programmable arraybased
design methodology is used for the first time to
implement a 10 GHz LC oscillator in a SiGe bipolar
technology. The array used was not optimised prior to this
design for the development of such circuits, and is used to
highlight some of the restrictions faced by the designer
when adopting an array-based approach. 10 GHz operation
is demonstrated with a phase noise of –85.5 dBc/Hz @
1MHz on first pass silicon. Whilst this performance is
inferior to a full custom LC solution, the array-based design
exceeds significantly the performance levels obtainable from
a ring oscillator implemented using full custom techniques
which meets the SONET jitter specifications. Detailed
analysis of the various phase noise contributions to the 10
GHz LC oscillator show that the performance is not
prohibitively compromised by the array-based design
approach. Together with the improved time-to-market
resulting from an array-based approach, this work makes a
compelling case for the viability and adoption of arraybased
design methodologies for a wide range of RF and
microwave applications.
Three's a crowd in two-and-a-half-party systems : how third parties have undermined their own policy objectives in five post-war democracies
Creators: name: Karnazes, Alexander John Peter
Publisher: name: University of British Columbia
Year: 2014

description: This study examines the manners in which third parties’ electoral results and shifts in policy have affected major parties’ policy positioning. I respond to the work of Adams and Merrill (2006) and of Nagel and Wlezien (2010) by analyzing two-and-a-half-party systems that contain a centrist or a non-centrist third party. The cases include parties elected by a variety of voting systems and with various political traditions. Ultimately, I find that, over the past half-century, third parties in Austria, Canada, Germany, Ireland, and Luxembourg have regularly undermined the policy objectives most commonly associated with the these parties. A modified version of Nagel and Wlezien’s occupied-centre effect, which I call the occupied-position effect, has been present in the five examined national party systems. This finding, however, is only applicable with respect to shifts in policies that have principally been associated with third parties, what I call “key policies”, as opposed shifts in general left-right positions. The evidence presented in this study shows that the major parties in two-and-a-half-party systems have consistently responded to third-party electoral gains by becoming less supportive of third parties’ key policies. Three such policy areas are examined: welfare spending, market liberalization, and ethnonationalism. I also show that there are effects from third parties changing their own policy positions, independent of how well they do at the polls. Exacerbating the dilemma that the analyzed third parties have faced, a key-policy version of Adams and Merrill’s reverse-shift effect appears to have been present in the examined party systems. This means that the major parties have followed shifts in third parties’ policy positions by shifting their positions in the opposite directions. Thus, third parties have undermined their own policy objectives when they have expressed (and shifted to) strong key-policy positions during election campaigns. Though third parties do have a strategic option pertaining to this effect – expressing insincere, moderated policy preferences – the long-term applicability of this tactic appears limited, especially in conjunction with the problems third parties have faced regarding the occupied-position effect.

description: Measurements of tau lepton, because of its long lifetime, large mass and parity sensitive couplings lead to broad physics interest. From the perspective of high-energy experiments such as at LHC, knowledge of tau lepton properties offers an important ingredient of new physics signatures. From the perspective of lower energies, tau lepton decays constitute an excellent laboratory for hadronic interactions. At present,hundreds of millions of tau decays have been amassed by both Belle and BaBar experiments. It is of utmost importance to represent such data in a form as useful for general applications as possible. In the present paper we describe the set of form factors for hadronic tau decays based on Resonance Chiral Theory. The technical implementation of the form factors in FORTRAN code is also explained. It is shown how it can be installed into TAUOLA Monte Carlo program. Then it is rather easy to implement into software environments of not only Belle and BaBar collaborations but also for FORTRAN and C++ applications of LHC. Description of the current for each tau decay mode is complemented with technical numerical tests. The set is ready for fits, parameters to be used in fits are explained. Arrangements to work with the experimental data not requiring unfolding are prepared. Hadronic currents, ready for confrontation with the tau decay data, but not yet ready for the general use, cover more than 88% of hadronic tau decay width.

description: In this paper, a high-efficiency rectifying
antenna (rectenna) element, based on a novel E-pHEMT
detector, is proposed. The slightly positive threshold voltage
in this technology, allows its use on resistive detectors
without applying an auxiliary gate bias. Based on an
adequate selection of the DC load resistor, as well as the
drain and gate impedance conditions, the losses on the RF to
DC conversion process are reduced. A high gain aperture
coupled patch is finally designed, assuring optimum
impedance values at the fundamental and second harmonic.
Using a rectenna loading of 47   , a 85.4% measured overall
efficiency is achieved.

description: In the last few years, the Internet throughput, usage and reliability have increased almost exponentially. The introduction of broadband wireless mobile ad hoc networks (MANETs) and cellular networks together with increased computational power have opened the door for a new breed of applications to be created, namely real-time multimedia applications. Delivering real-time multimedia traffic over a complex network like the Internet is a particularly challenging task since these applications have strict quality-of-service (QoS) requirements on bandwidth, delay, and delay jitter. Traditional Internet protocol (IP)-based best effort service is not able to meet these stringent requirements. The time-varying nature of wireless channels and resource constrained wireless devices make the problem even more difficult. To improve perceived media quality by end users over wireless Internet, QoS supports can be addressed in different layers, including application layer, transport layer and link layer. Cross layer design is a well-known approach to achieve this adaptation. In cross-layer design, the challenges from the physical wireless medium and the QoS-demands from the applications are taken into account so that the rate, power, and coding at the physical (PHY) layer can adapted to meet the requirements of the applications given the current channel and network conditions. A number of propositions for cross-layer designs exist in the literature. In this chapter, an extensive review has been made on these cross-layer architectures that combine the application-layer, transport layer and the link layer controls. Particularly, the issues like channel estimation techniques, adaptive controls at the application and link layers for energy efficiency, priority based scheduling, transmission rate control at the transport layer, and adaptive automatic repeat request (ARQ) are discussed in detail.

description: Die Biokompatibilität von Prothesenbasiskunststoffen lässt sich durch eine Nachpolymerisation verbessern. Potentiell schädigende Inhaltsstoffe wie Restmonomer und Dibenzoylperoxid werden dabei umso stärker reduziert, je höher die Temperatur ist und je länger die Wärmenachbehandlung andauert. Ziel dieser Studie war es, den Einfluss einer Nachpolymerisation auf das Formverhalten verschiedener konventioneller Prothesenbasiskunststoffe durch Messung des dorsalen Randspalts und die Bestimmung des Transversalmaßes an prothesenähnlichen Probekörpern zu untersuchen. Die Ergebnisse zeigen, dass zur Vermeidung von klinisch bedeutsamen Dimensionsänderungen sowohl die Wahl der Nachpolymerisationstemperatur und -zeit, als auch die Entscheidung zu einer Einbettung für jeden untersuchten Kunststoff individuell getroffen werden muss. Dabei sollte Kallocryl A in Gips eingebettet für maximal 12 Stunden bei 75 °C, PalaXpress eingebettet für maximal 2 Stunden bei 95 °C oder 12 Stunden bei 75 °C und Kallocryl B frei im Wasserbad bei 95 °C für 12 Stunden nachpolymerisiert werden.
description: The post-polymerization content of methyl methacrylat and benzoyl peroxide has been associated with the physiologic compatibility of denture base acrylic resins. Content of MMA and BPO can, however, be reduced in polymerized acrylic resin by an additional curing cycle. This study evaluated the dimensional stability of acrylic resins subjected to an additional curing cycle. Transverse dimensions, and gaps between the customized cast and polymerized acrylic resin were evaluated and verified using a light microscope. Results indicate that each resin should be individually evaluated with regard to additional curing cycles, and the temperature, time and molding selected.

description: This paper describes the complete design
methodology used to implement a MMIC lineariser in
0.25um pHemt GaAs technology. Theoretical concepts and
numerical simulations of a new pre-distorter prototype
designed for a wide band and high linearity power amplifier
are presented. Modeling and process variations sensitivity
has been accurately taken into account during the
implementation of the lineariser architecture allowing a
time effective and safe design approach. Several parts of the
main amplifier have been reused in the pre-distorter design
reducing the total development lead-time and the risk of
model inaccuracies.
The implemented predistortion topology has been verified
using Agilent ADS simulator showing an improvement up to
10 dBc in third order intermodulation distortion (IM3) over
a relative bandwidth of 28%. These results are also
confirmed by experimental characterizations that
demonstrate the effectiveness of the new pre-distortion
scheme and implementation methodology.

description: This paper shows a simple practical method of extracting the major parameters in the VBIC model used on a GaAs HBT. The method was developed mainly for the circuit designer, who want to have an easy practical way of extracting good model parameters from a few simple measurements, and due to the lack of such simple methods for the VBIC model used on GaAs HBT. The extraction method is based on a semi-analytic approach. The method includes a simple analytic extraction of the non-ideal current sources Iben, Nen, Ibcn and Ncn. The algorithm for the parameter extraction is presented. To verify the method, measurements from Caswell Technology were used. The extracted model shows good agreement with measurements.

description: Effective interactions involving both the top quark and the Higgs field are among the least constrained of all possible (gauge invariant) dimension-six operators in the Standard Model. Such a handful of operators, in particular the top quark chromomagnetic dipole moment, might encapsulate signs of the new physics responsible for electroweak symmetry breaking. In this work, we compute the contributions of these operators to inclusive Higgs and t tbar h production. We argue that: i) rather strong constraints on the overall size of these operators can already be obtained from the current limits/evidence on Higgs production at the LHC; ii) t tbar h production will provide further key information that is complementary to t tbar measurements, and the possibility of discriminating among different contributions by performing accurate measurements of total and differential rates.

description: Nonparametric control charts that can detect arbitrary distributional changes are highly desirable due to their flexibility to adapt to different distributional assumptions and changes. However, most of the nonparametric control charts in the literature either can only detect location changes, or involve intensive computation. In this article, we propose a new nonparametric adaptive CUSUM chart. The proposed control chart can detect arbitrary distributional changes and is computationally efficient. Its self-starting nature makes the proposed control chart applicable to situations where no sufficiently large reference data are available. The proposed control chart also has a built-in post-signal diagnostics function that can identify what kind of distributional changes have occurred after an alarm. Our simulation study and real data analysis show that the proposed control chart performs well across a broad range of settings, and compares favorably with existing nonparametric control charts.

description: This paper presents an equivalent circuit model for common-emitter current-gain collapse in multi-finger HBTs.The collapse of current-gain is an undesirable phenomenon,which occurs in multi-finger HBTs when they are operated at high power density.The collapse manifests itself by a distinct abrupt decrease of collector current in the output characteristics of the HBT.Until now,there hasn ’t been an equivalent circuit model to simulate the current collapse behavior of multi-finger HBTs.In this paper,for the first time,the large-signal Ebers-Moll model is modified to include the effect of current-gain collapse.Hence,the model presented here is a big step towards predicting the behavior of multi-finger HBTs under high power and high frequency operating con- ditions.Also,the self-heating effect which gives rise to the negative output resistance is included in the equivalent circuit without the use of an external thermal feedback circuit.Hence,the equivalent circuit is much simpler to implement and easier to analyze. Moreover,it includes the phenomenon of current-gain collapse.The model is applied to an InGaAs/GaAs multi-finger heterojunction bipo- lar transistor (HBT)and the simulated and the measured characteristics are compared in order to validate the model.Both the small signal and large signal models are implemented as user-defined models in the commercial circuit simulator,LIBRA.

description: We show that there are extremely simple signal detection schemes where the finiteness of energy resources places no limit to the resolution. On the contrary, larger resolution can be obtained with lower energy. To this end the generator of the signal-dependent transformation encoding the signal information on the probe state must be different from the energy. We show that the larger the deviation of the probe state from being minimum-uncertainty state, the better the resolution.

description: The growth of highly uniform, state-of-the-art InGaP/GaAs heterojunction bipolar transistors is demonstrated in a multi-wafer 6-inch configuration (AIX 2600). The uniformity of thickness, doping, composition, interface properties and minority carrier lifetime are assessed by electrical and structural characterization measurements, and shown to vary by less than ±3% across the wafer. The dc current gain versus base sheet resistance on a high gain structure, has a non-linear dependence on base sheet resistance, typical of high performance InGaP/GaAs HBTs.

description: We present the first impact ionization investigation by electroluminescence of InxAl1-xAs /InxGa1-xAs metamorphic High Electron Mobility transistors on GaAs. Two Indium content are investigated. First we observe the decrease of the detrimental effect of impact ionization with the decrease of the Indium content. Second, the electroluminescence measurements illuminate the functional relationship between impact ionization and the kink effect. In these metamorphic HEMT’s, we suggest that both kink effect and impact ionization threshold are originated to detrapping process of deep levels in the large band gap layer.
A barley gene cluster for the biosynthesis of diterpenoid phytoalexins

description: Phytoalexins, which are specialized metabolites, contribute to chemical defense of plants against pathogens. We characterized a biosynthetic gene cluster in barley that is responsible for the production of a group of labdane diterpenoids, with the backbone named hordediene. Infection of barley roots by the fungal pathogen Bipolaris sorokiniana (Bs) induces their production and secretion. Using heterologous expression in yeast and Nicotiana benthamiana, we can produce and structurally characterize several hordediene derived diterpenoids, including the most abundant one referred to as 21. Barley mutants lacking the diterpene synthase are unable to produce these diterpenoids and, surprisingly, show reduced colonization by Bs. The growth of Bs is only negligibly affected by 21 while other pathogenic fungus, Fusarium culmorum is inhibited. Bs can metabolize 21 to two distinct groups of derivatives. Consequently, our findings indicate Bs has developed adaptation mechanisms at the metabolite level to enhance colonization of barley roots.
description: Phytoalexine, die spezialisierte Metabolite sind, tragen zur chemischen Abwehr von Pflanzen gegen Pathogene bei. Wir haben einen biosynthetischen Gencluster in Gerste charakterisiert, der für die Produktion einer Gruppe von Labdan-Diterpenoiden verantwortlich ist, deren Grundstruktur als Hordedien bezeichnet wird. Die Infektion von Gerstenwurzeln durch den pilzlichen Pathogen Bipolaris sorokiniana (Bs) induziert deren Produktion und Ausschüttung in den Wurzelraum. Durch heterologe Expression in Hefe und Nicotiana benthamiana können wir mehrere aus Hordedien abgeleitete Diterpenoide herstellen und strukturell charakterisieren, einschließlich des am intensivsten vorkommenden mit der Bezeichnung 21. Gerstenmutanten, die die Diterpensynthase-Gene nicht besitzen, können diese Diterpenoide nicht produzieren und zeigen überraschenderweise eine verringerte Besiedlung durch Bs. Das Wachstum von Bs wird durch 21 nur vernachlässigbar beeinflusst, während ein anderer pathogener Pilz, Fusarium culmorum, gehemmt wird. Bs kann 21 in zwei verschiedene Gruppen von Derivaten metabolisieren. Folglich deuten unsere Ergebnisse darauf hin, dass Bs Anpassungsmechanismen auf der Metabolitebene entwickelt hat, um seine Besiedlung in Gerstenwurzeln zu verbessern.

description: The non-equilibrium spin dynamics of a one-dimensional system of repulsively interacting fermions is studied by means of density-matrix renormalization-group simulations. We focus on the short-time decay of the oscillation amplitudes of the centers of mass of spin-up and spin-down fermions. Due to many-body effects, the decay is found to evolve from quadratic to linear in time, and eventually back to quadratic as the strength of the interaction increases. The characteristic rate of the decay increases linearly with the strength of repulsion in the weak-coupling regime, while it is inversely proportional to it in the strong-coupling regime. Our predictions can be tested in experiments on tunable ultra-cold few-fermion systems in one-dimensional traps.

description: Lysosomale Cysteinproteasen (Cathepsine) besitzen eine wesentliche Bedeutung beim Umbau zellulärer und extrazellulärer Proteine. Diese Enzyme spielen eine wichtige Rolle in pathologischen Prozessen, die mit einer Gewebedestruktion verbunden sind. Dreidimensionale Strukturmodelle der Cysteinproteasen Cathepsin K, S, H und F wurden unter Verwendung verschiedener Verfahren des Homology Modelling auf der Grundlage der Röntgenkristallstrukturen von verwandten Enzyme, wie z. B. Cathepsin L, Papain und Actinidin generiert. Diese Strukturmodelle zeichnen sich durch eine hohe Genauigkeit aus und erfüllen darüber hinaus sehr gut verschiedenste Kriterien bei der Überprüfung der Strukturen. Außerdem konnte die Lage und die Konformation der Minikette, die einen wesentlichen Bestandteil von Cathepsin H bildet, ermittelt werden. Als Ergebnis der Analysen der elektrostatischen Potentiale der molekularen Oberfläche der Cathepsine B, K, L, S, H und F und der Ermittlung bevorzugter Bindungsstellen im katalytisch aktiven Bindungszentrum dieser Enzyme wurden neue potente Liganden (Substrate und Inhibitoren) entwickelt werden. Über Dockingstudien wurden die nichtbindenden Wechselwirkungsenergien und Dissoziationskonstanten der Cathepsin-Ligand-Komplexe berechnet. Die experimentell bestimmten kinetischen Daten einiger Komplexe bestätigen die theoretisch getroffenen Vorhersagen über die Affinität der entwickelten Liganden zum jeweiligen Cathepsin.
description: The lysosomal cysteine proteases (cathepsin) are widely distributed among living organisms. The papain-like cathepsins have been implicated in a variety of physiological processes and their proteolytic activities may also be relevant to many human diseases. Three-dimensional models of the cysteine proteases human cathepsins K, S, H, and F were built by homology modeling based on the crystal structures of related enzymes like cathepsin L, papain, and actinidin, for instance. The structure models were found to have good stereochemistry, and meet reasonably well various criteria for validating the overall correctness of the structures. Moreover, the position and the conformation of the minichain as an essential part of the cathepsin H could be determined. As a result of an analysis of the electrostatic potentials on the molecular surface of the cathepsins B, L, K, S, H, and F and the determination of the favorable subsites of the active site of these enzymes new potent ligands (substrates and inhibitors) for the cysteine proteases cathepsins L, K, and F were designed. Based on docking studies the non-bonded interaction energies and the dissociation constants of the ligands with the cathepsins were calculated. The kinetic data confirm the design hypothesis about the substrate and inhibitory potency by experimental data of cathepsin ligand complexes.
SPARC modulates the spinal cord neuroimmune response in experimental autoimmune encephalomyelitis

description: SPARC (Secreted Protein Acidic and Rich in Cysteine), a secreted glycoprotein, regulates proliferation, migration and differentiation. SPARC is highly expressed in glia and blood vessels during CNS development. SPARC expression is maintained in tissues undergoing rapid turnover and its expression is highly upregulated during injury or disease. SPARC’s modulatory activity in glia and endothelia during injury lead us to investigate the role of SPARC in an animal model of CNS inflammation and demyelination with known BBB dysfunction: Experimental Autoimmune Encephalomyelitis (EAE). We discovered that, in the spinal cord, SPARC is expressed and localized to developing endothelia and radial glia but is down-regulated and retained in specific subpopulations of glia in the adult spinal cord. During the repair response of EAE, CNS glia and endothelia recapitulate their developmental SPARC expression. Furthermore, in the absence of SPARC, EAE onset is delayed even though there is increased blood-brain barrier (BBB) permeability. We provide evidence that SPARC may play a role in neuro-immune and endothelial cross-talk during the repair response following EAE.
