Selection and Dimensioning of Slice-Based RAN Controller for Adaptive Radio Resource Management (2017)

This paper discusses a resource management abstraction framework which involves the clustering of densely deployed access points and the selection of access nodes to act as cluster schedulers based on the RAN characteristics, the resource situation and the network slice requirements. To this end, the adaptive placement of Radio Resource Management (RRM) functionalities to the RAN nodes and the interactions among functionalities are determined on per slice basis. By taking into account the slice requirements, the backhaul#x002F;access channel conditions and the traffic load, a central management entity assigns RRM functionalities to the controllers with different levels of centralization in order to meet the per slice SLAs (in terms of throughput, reliability, latency). The controller, cluster and RRM split configuration problems are formulated and interpreted as three dependent graph-based sub- problems, where heuristic approaches with low complexity and signalling cost are proposed within this framework.

The bovine alveolar macrophage. II. In vitro studies with Pasteurella haemolytica. (1978)

Bovine alveolar macrophages were cultured in vitro and challenged with suspensions of live and dead bacteria. These cells showed severe cytotoxic morphological changes and a low rate of phagocytosis after exposure to live Pasteurella haemolytica type I was readily phagocytosed and produced only mild cytotoxic changes.
Interfacing Detectors to Triggers And DAQ Electronics (1999)

The complete design of the front-end electronics interfacing LHCb detectors, Level-0 trigger and higher levels of trigger with flexible configuration parameters has been made for (a) ASIC implementation, and (b) FPGA implementation. The importance of approaching designs in technology-independent form becomes essential with the actual rapid electronics evolution. Being able to constrain the entire design to a few types of replicated components: (a) the fully programmable 3D-Flow system, and (b) the configurable front-end circuit described in this article, provides even further advantages because only one or two types of components will need to migrate to the newer technologies. To base on today's technology the design of a system such as the LHCb project that is to begin working in 2006 is not cost-effective. The effort required to migrate to a higher-performance will, in that case, be almost equivalent to completely redesigning the architecture from scratch. The proposed technology independent design with the current configurable front-end module described in this article and the scalable 3D-Flow fully programmable system described elsewhere, based on the study of the evolution of electronics during the past few years and the forecasted advances in the years to come, aims to provide a technology-independent design which lends itself to any technology at any time. In this case, technology independence is based mainly on generic-HDL reusable code which allows a very rapid realization of the state-of-the-art circuits in terms of gate density, power dissipation, and clock frequency. The design of four trigger towers presently fits into an OR3T30 FPGA. Preliminary test results (provided in this paper) meet the functional requirements of LHCb and provide sufficient flexibility to introduce future changes. The complete system design is also provided along with the integration of the front-end design in the entire system and the cost and dimension of the electronics.
In vitro Response of Articular Cartilage from Mature Mice to Human Transforming Growth Factor Beta (1994)

The ability of human transforming growth factor-beta 1 (hTGF-beta 1) to induce proliferation and matrix synthesis in articular cartilage of aging mice was studied using an organ culture system of mandibular condylar cartilage. An increased incorporation of 3H-thymidine into DNA and of 35S-SO4 into sulfated glycosaminoglycans was observed in cultures supplemented with 1-10 ng/ml TGF-beta and with 1% fetal calf serum. In these cultures numerous clusters of chondrocytes containing a well-developed rough endoplasmic reticulum were seen. Articular cartilage from mature animals often develops osteoarthritic degenerative lesions, thus the induction of cell proliferation and of matrix synthesis may be an indication of a tissue repair process in cartilage from maturing animals.
The Nonconsecutive Disulfide Bond of Escherichia coli Phytase (AppA) Renders It Dependent on the Protein-disulfide Isomerase, DsbC (2005)

The formation of protein disulfide bonds in the Escherichia coli periplasm by the enzyme DsbA is an inaccurate process. Many eukaryotic proteins with nonconsecutive disulfide bonds expressed in E. coli require an additional protein for proper folding, the disulfide bond isomerase DsbC. Here we report studies on a native E. coli periplasmic acid phosphatase, phytase (AppA), which contains three consecutive and one nonconsecutive disulfide bonds. We show that AppA requires DsbC for its folding. However, the activity of an AppA mutant lacking its nonconsecutive disulfide bond is DsbC-independent. An AppA homolog, Agp, a periplasmic acid phosphatase with similar structure, lacks the nonconsecutive disulfide bond but has the three consecutive disulfide bonds found in AppA. The consecutively disulfide-bonded Agp is not dependent on DsbC but is rendered dependent by engineering into it the conserved nonconsecutive disulfide bond of AppA. Taken together, these results provide support for the proposal that proteins with nonconsecutive disulfide bonds require DsbC for full activity and that disulfide bonds are formed predominantly during translocation across the cytoplasmic membrane.
Examination of <i>Campylobacter jejuni</i> Putative Adhesins Leads to the Identification of a New Protein, Designated FlpA, Required for Chicken Colonization (2009)

Campylobacter jejuni colonization of chickens is presumably dependent upon multiple surface-exposed proteins termed adhesins. Putative C. jejuni adhesins include CadF, CapA, JlpA, major outer membrane protein, PEB1, Cj1279c, and Cj1349c. We examined the genetic relatedness of 97 C. jejuni isolates recovered from human, poultry, bovine, porcine, ovine, and canine sources by multilocus sequence typing (MLST) and examined their profile of putative adhesin-encoding genes by dot blot hybridization. To assess the individual contribution of each protein in bacterium-host cell adherence, the C. jejuni genes encoding the putative adhesins were disrupted by insertional mutagenesis. The phenotype of each mutant was judged by performing in vitro cell adherence assays with chicken LMH hepatocellular carcinoma epithelial cells and in vivo colonization assays with broiler chicks. MLST analysis indicated that the C. jejuni isolates utilized in this study were genetically diverse. Dot blot hybridization revealed that the C. jejuni genes encoding the putative adhesins, with the exception of capA, were conserved among the isolates. The C. jejuni CadF, CapA, Cj1279c, and Cj1349c proteins were found to play a significant role in the bacterium's in vitro adherence to chicken epithelial cells, while CadF, PEB1, and Cj1279c were determined to play a significant role in the bacterium's in vivo colonization of broiler chicks. Collectively, the data indicate that Cj1279c is a novel adhesin. Because Cj1279c harbors fibronectin type III domains, we designated the protein FlpA, for fibronectin-like protein A.
Implementation Issues In Map Joint Source/channel Coding (2005)

One of Shannon's many fundamental contributions was his result that source coding and channel coding can be implemented separately without any loss of optimality. However, the assumption underlying this result may at times be violated in practice. Various joint source/channel coding approaches have been developed for handling such situations. A MAP approach to joint source/channel coding has been proposed which uses a MAP decoder and a modification of the source coder to provide error correction. We present various implementation strategies for this approach and provide results for an image coding application.
Multimodal Sparse Representation for Anomaly Classification in A Robot Introspection System (2018)

Robot introspection is expected to greatly aid longer-term autonomy of autonomous systems. By equipping robots with skills that allow them to assess the quality of their sensory data, robots can detect and classify anomalies and recover from them. However, the variability and complexity of multimodal sensory data exacerbates anomaly classification in practical applications. This work contributes a sparse representation for multimodal time-series for relevant features while preserving classification accuracy. We examine multivariate features in the time and frequency domains and analyze the correlation across all sensory signal dimensions. The sparse process consists of four phases: (i) preprocessing and synchronization of raw time signals; (ii) statistical formulations for each sensor, (iii) evaluation of feature significance using hypothesis testing, and (iv) raw multimodal sample representation with the concatenating feature vector. We test the performance of the sparse anomaly classification through the enactment of a kitting experiment designed to package 6 different objects from a given placement region to a specific container. Aaccuracy, precision, recall, and f-score are used to evaluate the sparse representation performance on various kinds of existing methods.

Oligomere aus gleichsinnig angeordneten Chalkon-Bausteinen (1999)

A convergent and coupled synthesis was developed for the cross-conjugated oligomers 1a–d which contain one to four chalcone building blocks arranged in the same direction. The preparation started with 1,4-dipropoxybenzene (2) and led via bromination (2 → 3,6) and Bouveault reactions to the carbonyl components 4, 5 and 7. Protection of the formyl group (7 → 8) and a further Bouveault reaction yielded the bifunctional compound 9 which played a central role for the extension of the chain. The substituted benzaldehyde 4 was transformed by this means to the aldehydes 10, 11 and 12. The compounds 4 and 10–12 reacted in the final step with the acetophenone 5 to the desired oligomers 1a–d.

A 1.6Gb/s 16-level superposed APSK MODEM using newly developed baseband signal processing coherent demodulator is described. The MODEM has much improved performance characteristics while having much simplified configuration comparing with the already reported one. Jitter power of the recovered carrier is less than -36dB and required C1/N for BER of 10/sup -9/ is better than 25.4dB through the MODEM loop back test (BT = 1.35).

The major goal of this paper is to provide an overview of recommendation approaches and to discuss their relevance for AGILE.
Modified Smith Predictor for Controlling Integrator/Time Delay Processes (1996)

Astrom et al. have proposed a new Smith predictor to control the process with an integrator and a long time delay. Though the method provides significant performance improvement, it fails to give effective tuning rules even when the integral constant is equal to 1. In this paper the method is extended to the general integrator/time delay process. A clearer and more logical design procedure is formulated, and simple tuning rules are developed. It shows that there is a minimum-order compensator for the process. Illustrative examples show the superiority of the proposed scheme in terms of both closed-loop performance and robustness.
Determination of the vacuum outgassing properties of elastic closures by mass spectrometry. (1981)

This paper reports the results of a mass spectrometric study of the outgassing properties of elastic closures. The closures examined were those typically used in the lyophilization process. The detection system was an ion differentially pumped quadrupole mass spectrometer. Outgassing studies of the closures were conducted in a glass vacuum system and a 24-ft2 vacuum freeze dryer. Examination of the mass spectra of vapors from the glass system is discussed. Results of studies conducted in a 24-ft2 vacuum freeze dryer indicate the presence of closure outgassing vapors at various shelf temperatures.
Learning Laplacian Matrix in Smooth Graph Signal Representations (2014)

The construction of a meaningful graph plays a crucial role in the success of many graph-based representations and algorithms for handling structured data, especially in the emerging field of graph signal processing. However, a meaningful graph is not always readily available from the data, nor easy to define depending on the application domain. In particular, it is often desirable in graph signal processing applications that a graph is chosen such that the data admit certain regularity or smoothness on the graph. In this paper, we address the problem of learning graph Laplacians, which is equivalent to learning graph topologies, such that the input data form graph signals with smooth variations on the resulting topology. To this end, we adopt a factor analysis model for the graph signals and impose a Gaussian probabilistic prior on the latent variables that control these signals. We show that the Gaussian prior leads to an efficient representation that favors the smoothness property of the graph signals. We then propose an algorithm for learning graphs that enforces such property and is based on minimizing the variations of the signals on the learned graph. Experiments on both synthetic and real world data demonstrate that the proposed graph learning framework can efficiently infer meaningful graph topologies from signal observations under the smoothness prior.
Glutathione Ester But Not Glutathione Protects Against Cisplatin-Induced Ototoxicity in a Rat Model (2003)

Glutathione (GSH) provides an important antioxidant and detoxification pathway. We tested to determine if direct administration of GSH or GSH ester could reduce cisplatin- (CDDP) induced ototoxicity. We tested eight groups of five rats each: a control group, a group receiving 16 mg/kg ip CDDP infused over 30 minutes, and six groups receiving either GSH or GSH ester at 500, 1000, or 1500 mg/kg intraperitoneally 30 minutes prior to 16 mg/kg CDDP. Auditory brainstem response thresholds were measured for click and tone-burst stimuli at baseline and 3 days later. Outer hair cell (OHC) loss was measured for the apical, middle and basal turns. The 500 mg/kg GSH ester reduced hearing loss and OHC loss, but protection decreased as dosage increased, suggesting possible toxicity. GSH was not significantly protective. The best GSH ester protection was less than we have previously reported with D-methionine.
Introduction (1988)

One of the primary concerns of the engineer is the design and construction of machines many times more powerful than himself or any of his domestic animals. The development of this skill over the centuries has been fundamental to the growth of civilization. Man’s early efforts to harness the power of wind and water owed very little to engineering science, and indeed the early steam engine was a practical reality before the science of thermodynamics was firmly established. In contrast, there is now a vast fund of engineering knowledge behind the present day prime movers.
[Development for the determination of band 5b tartrate-resistant acid phosphatase activity in serum]. (2001)

Band 5 Tartrate-resistant acid phosphatase(TRACP; EC 3.1.3.2) consists of two isoenzymes, bands 5a and 5b, of which band 5b TRACP, an enzyme expressed in bone-resorbing osteoclasts, is secreted into the circulation during bone resorption. Band 5b TRACP was measured kinetically in serum as tartrate-resistant fluoride-sensitive heparin-resistant ACP with 2,6-dichloro-4-acetylphenyl phosphate as substrate at pH6.6. The within-run(n = 20) and between-run(n = 20) CVs of band 5b TRACP activity were 3.3-5.8% and 5.0-7.3%, respectively. The reference range of band 5b TRACP activity in males(n = 72) and females(n = 87) 20-39 years of age by this method were 3.7-12.5 U/l and 2.7-9.9 U/l, respectively. The band 5b TRACP value was significantly higher in post-menopausal women compared with the menstruating women. The relationship of band 5b TRACP and ultrasound findings in healthy women aged 31-75 years(n = 139) were inversely correlated with stiffness(r = -0.401), speed of sound(SOS; r = -0.386) and broadband ultrasound attenuation(BUA; r = -0.338). These results suggest that band 5b TRACP may be a useful in the evaluation of bone turnover.
Variable capacitors in meander-suspended superconducting microbridge technology for high frequency applications (2005)

Variable capacitors in the fF to pF capacitance range are very interesting for high frequency applications like variable filters, couplers, resonators, etc. Our recent development permits to use meander-like suspensions for electrostatically actuated microbridges in Niobium (Nb) techno- logy (see Fig. 1). The surface mounted fabrication procedure allows for integration of these devices with the standard Nb tunnel diode fabrication process as used for radio astronomical heterodyne detectors and superconducting electronic circuitry. We present the fabrication procedure, first meander suspended devices with a low actuation voltage range, and two filter designs for 22 GHz tunable band pass filters.
Efficiency limits of photovoltaic fluorescent collectors (2005)

This paper examines the thermodynamic limits of photovoltaic solar energy conversion by fluorescent collectors. The maximum efficiency of a fluorescent collector corresponds to the Shockley–Queisser limit for a nonconcentrating solar cell with a single bandgap energy. To achieve this efficiency, the collector requires a photonic structure at its surface that acts as an omnidirectional spectral band stop filter. The large potential of photonic structures for the efficiency enhancement of idealized as well as real fluorescent collectors is highlighted.
Adiabatic polymer-glass-waveguide all-optical switch (1994)

We propose an adiabatic all-optical switch that is composed of an asymmetric Y-branch ion-exchanged glass waveguide with a strip of nonlinear polymer loaded on top of one branch. The properties of nonlinear wave propagation in the device are investigated in detail. By extending the effective-index method to the analysis of nonlinear waveguides, we calculate the nonlinear dispersion curves in successive sections to explain the evolution of normal modes in the device. As the multivalued propagation constants exist in the tapered directional coupler region, the device possesses an abrupt switching behavior and nonreciprocal properties. To demonstrate nonlinear switching behaviors in the Y-branch waveguide further, we employ a beam propagation method to simulate optical-field propagation. The inputs by three different ports are investigated, and the results agree well with the dispersion-curve analysis.
A 125I-radioimmunoassay for measuring androstenedione in serum and in blood-spot samples from neonates. (1989)

We developed a radioimmunoassay with a gamma-emitting radioligand to measure androstenedione in human serum and in dried blood-spot samples from newborns. Antisera were raised in rabbits against androstenedione linked to bovine serum albumin at positions 3, 6, or 11 on the steroid nucleus. Radioligands were prepared by linking [125I]iodohistamine at positions 3, 6, or 11. Linkages were through either carboxymethyloxime or hemisuccinate bridges. All label and antibody combinations were examined, and the most sensitive and specific combination (antiserum raised against androstenedione-3-carboxymethyloxime-bovine serum albumin with an androstenedione-carboxymethyloxime-[125I]iodohistamine label) was selected for full evaluation. We report the performance of these selected reagents in an immunoassay for androstenedione in both serum and dried blood-spot samples from neonates. We measured concentrations of androstenedione in serum under normal and pathological conditions such as congenital adrenal hyperplasia and polycystic ovarian disease. Diurnal variation in normal men was observed. Androstenedione was measured in blood spots from neonates born at term or prematurely, with respiratory distress syndrome, or with congenital adrenal hyperplasia.
