Wireless Environment as a Service Enabled by Reconfigurable Intelligent Surfaces: The RISE-6G Perspective (2021)

The design of 6th Generation (6G) wireless networks points towards flexible connect-and-compute technologies capable to support innovative services and use cases. Targeting the 2030 horizon, 6G networks are poised to pave the way for sustainable human-centered smart societies and vertical industries, such that wireless networks will be transformed into a distributed smart connectivity infrastructure, where new terminal types are embedded in the daily environment. In this context, the RISE-6G project aims at investigating innovative solutions that capitalize on the latest advances in the emerging technology of Reconfigurable Intelligent Surfaces (RISs), which offers dynamic and goal-oriented radio wave propagation control, enabling the concept of the wireless environment as a service. The project will focus on: i) the realistic modeling of RIS-assisted signal propagation, ii) the investigation of the fundamental limits of RIS-empowered wireless communications and sensing, and iii) the design of efficient algorithms for orchestrating networking RISs, in order to implement intelligent, sustainable, and dynamically programmable wireless environments enabling diverse services that go well beyond the 5G capabilities. RISE-6G will offer two unprecedented proof-of-concepts for realizing controlled wireless environments in near-future use cases.
Detection of phase synchronization from the data: Application to physiology (2000)

Synchronization of coupled oscillating systems means appearance of certain relations between their phases and frequencies. Here we use this concept in order to address the inverse problem and to reveal interaction between systems from experimental data. We discuss how the phases and frequencies can be estimated from time series and present the techniques for detection and quantification of synchronization. We apply our approach to multichannel magnetoencephalography data and records of muscle activity of a Parkinsonian patient, and also use it to analyze the cardiorespiratory interaction in humans. By means of these examples we demonstrate that our method is effective for the analysis of systems interrelation from noisy nonstationary bivariate data and provides other information than traditional correlation (spectral) techniques.
Highly durable low CoO mass production version of 2-kHz ArF excimer laser for DUV lithography (2000)

We have succeeded in the commercialization of the world's first kHz ArF excimer laser for microlithography application. The ArF laser is expected to be the light source for the DUV lithography tools for sub-0.13 micron geometry semiconductor production. In this paper, we present the performance and advanced technologies of the newest model of the ArF excimer laser, which achieves 10W of output power with 0.5 pm bandwidth at 2 kHz. The pulse-to-pulse energy stability, 3 sigma is less than 10 percent and integrated energy stability is within +/- 0.3 percent. The durability performance is extended to 5 billion pulses, which provides affordable CoO for volume production.
WiLiTV: Reducing Live Satellite TV Costs Using Wireless Relays (2018)

The bandwidth required for TV content distribution is rapidly increasing due to the evolution of high definition TV (HDTV) and ultra HDTV. Service providers are constantly trying to differentiate themselves by innovating new ways of distributing content more efficiently with lower cost and higher penetration. We propose a cost-efficient wireless architecture [wireless live TV (WiLiTV)], consisting of a mix of wireless access technologies [satellite, Wi-Fi, and LTE/5G millimeter wave (mmWave) overlay links], for delivering live TV services. In the proposed architecture, live TV content is injected into the network at selected locations, consisting of some homes and/or cellular base stations, using satellite antennas. The content is then further distributed to other homes using a house-to-house Wi-Fi network or an LTE/5G mmWave overlay. We construct an optimal content distribution network with the minimum number of satellite injection points, while preserving the highest quality of experience, for different neighborhood densities. We evaluate the framework using time-varying demand patterns and a diverse set of home location data provided from an operational content distribution network. Our study demonstrates that this architecture reduces the overall cost by 60% compared with the traditional architecture. We have also shown that the WiLiTV is robust in its support for several TV formats.
Strains of the intestinal spirochaete Brachyspira pilosicoliattach to and aggregate erythrocytes (2014)

The anaerobic intestinal spirochaete Brachyspira pilosicoli colonizes the large intestine of various species of mammals and birds, where it may induce colitis. Strains of the spirochaete have also been isolated from the bloodstream of immunocompromised human patients and have been seen in liver sections, and a similar systemic spread was recently observed in experimentally infected chickens. Some other spirochaete species that may be present in blood attach to and aggregate erythrocytes, and this is believed to contribute to disease severity. The aim of the current study was to determine whether B. pilosicoli strains have the capacity to attach to and aggregate erythrocytes. Initially, four strains of B. pilosicoli were incubated with erythrocytes from sheep, cows, pigs, dogs, humans, chickens and geese, and were observed by phase-contrast microscopy. Only strain WesB attached, and this was only with erythrocytes from chickens and geese. Subsequently, six other strains of B. pilosicoli were tested just with goose erythrocytes, and five attached to and caused aggregation of the erythrocytes. Scanning and transmission electron microscopy demonstrated that spirochaetes abutted and apparently firmly attached to the erythrocyte membranes. Aggregation of erythrocytes by B. pilosicoli may contribute to disease severity in species that develop a spirochaetaemia.
High-bandwidth Modulation of H2/Syngas Fuel to Control Combustion Dynamics in Micro-Mixing Lean Premix Systems (2012)

The goal of this program was to develop and demonstrate fuel injection technologies that will facilitate the development of cost-effective turbine engines for Integrated Gasification Combined Cycle (IGCC) power plants, while improving efficiency and reducing emissions. The program involved developing a next-generation multi-point injector with enhanced stability performance for lean premix turbine systems that burn hydrogen (H2) or synthesis gas (syngas) fuels. A previously developed injector that demonstrated superior emissions performance was improved to enhance static flame stability through zone staging and pilot sheltering. In addition, piezo valve technology was implemented to investigate the potential for enhanced dynamic stability through high-bandwidth modulation of the fuel supply. Prototype injector and valve hardware were tested in an atmospheric combustion facility. The program was successful in meeting its objectives. Specifically, the following was accomplished: Demonstrated improvement of lean operability of the Parker multi-point injector through staging of fuel flow and primary zone sheltering; Developed a piezo valve capable of proportional and high-bandwidth modulation of gaseous fuel flow at frequencies as high as 500 Hz; The valve was shown to be capable of effecting changes to flame dynamics, heat release, and acoustic signature of an atmospheric combustor. The latter achievement indicates the viability of the Parker piezo valve technology for use in future adaptively controlled systems for the mitigation of combustion instabilities, particularly for attenuating combustion dynamics under ultra-lean conditions.
Worsening of Neurologic Syndrome in Patients With Wilson's Disease With Initial Penicillamine Therapy (1987)

We describe a patient with Wilson's disease who presented with neurologic disease, was treated with D-penicillamine, and suffered sudden neurologic deterioration coincident with therapy. Replicate brain magnetic resonance imaging examinations after six weeks and 11 months of penicillamine therapy documented the development of new brain lesions during this period, while liver biopsy specimen data disclosed that excellent hepatic decoppering had occurred. To develop information on the relative rarity or frequency of neurologic worsening with the initiation of penicillamine therapy, we conducted a retrospective survey of 25 additional patients with Wilson's disease who met the criteria of presenting with neurologic disease and having been treated with penicillamine. The replies indicate that, at least from the patient's viewpoint, this syndrome occurs frequently. We suggest that the cause of this distressing syndrome, and ways to mitigate or circumvent it, must be discovered.
A constant-current electrospinning system for production of high quality nanofibers (2008)

A constant-current electrospinning system has been successfully developed to produce high quality nanofibers. In order to keep at a certain value of the electric current, a proportional integral-derivative (PID) control action was employed, in which the PID parameters were manually tuned. The desired value of electric current was quickly achieved and no overshoot was observed in the system output. The restoration of the electric current due to a disturbance occurred rapidly.Poly(vinyl pyrrolidone) PVP nanofibers have been produced from a precursor solution prepared by dissolution of the PVP powder in a mixture of dimethyl formamide and ethanol using the constant-current electrospinning system. The cone jet shape observed at the end of the needle during the injection of the precursor solution became shorter with increasing electric current. The diameter of the PVP nanofibers was very uniform and reduced with increasing electric current, which is consistent with the model.

Coacervation (2016)

This Glossary of Terms Related to Pharmaceutics is needed by practitioners in the field of pharmaceutics as this field fulfills an important and crucial role, different from the roles of other scientific disciplines involved in the drugmaking process. The glossary contains 168 definitions used in pharmaceutics. These are related to various aspects of this discipline, such as: (1) physicochemical characterization of pharmaceutical preparations and the active ingredients they contain; (2) unit operations used in the practice of pharmaceutics; (3) terms related to the various dosage forms; (4) terms related to the various modes and routes of drug delivery; (5) terms used in pharmacokinetics and biopharmaceutics in general; and additional miscellaneous terms. The field of pharmaceutics itself is of a multidisciplinary nature as its practitioners come from a variety of disciplines, such as chemistry or various biological sciences, thus a glossary containing authoritative definitions would be useful for them. The terms used in pharmaceutics are rarely covered by existing glossaries, and in the cases they are, their definitions are often inappropriate for the field of pharmaceutics and require new or modified definitions to better fit the new context.
Adult T-cell leukemia/lymphoma in Jamaica and its relationship to human T-cell leukemia/lymphoma virus type I-associated lymphoproliferative disease. (1984)

We had shown previously that the prevalence of human T-cell leukemia/lymphoma virus type I (HTLV-I)-antibody positivity is high in Jamaican non-Hodgkin's lymphoma (NHL) patients and that virus-positive patients have the clinical features and poor prognosis of adult T-cell leukemia/lymphoma (ATL). Sixty-two % of 45 NHL patients diagnosed consecutively between 2/1/82 and 1/31/84 and studied prospectively were HTLV-I-antibody positive. Skin involvement (38%), hypercalcemia (44%), and leukemia (40%) were unusually prevalent and there was a strong association (p less than 0.05) with HTLV-I-antibody positivity. Fifty-two % of the patients had bone marrow infiltration, and 74% of these patients were HTLV-I-antibody positive (p = 0.06). Lymphadenopathy (96%), hepatomegaly (60%), and splenomegaly (25%) were detected with about the same frequency as in other series of NHL patients with advanced disease, and 61-88% of these patients were HTLV-I-antibody positive. Patients were classified into those with "typical ATL" (NHL associated with 2 of the 4 features i) hypercalcemia; ii) histologically proven skin infiltration; iii) leukemia; and iv) bone marrow infiltration, providing that the morphology of infiltrating or leukemic cells was characteristic of ATL; those "consistent with ATL" (NHL associated with 1 of these 4 features); and "non-ATL" (NHL without any of these 4 additional features). Thirty-two (71%) of the NHL patients were ATL patients, i.e., had features typical of or consistent with ATL, and 78% of these were HTLV-I-antibody positive. HTLV-I provirus was detected in tumour cells of all HTLV-I-antibody positive patients tested. Three (23%) of the non-ATL patients were HTLV-I-antibody positive. There was no correlation between histopathological features and the clinical classification or HTLV-I-antibody positivity. Median survival of ATL and non-ATL patients was 16 and 53 weeks. Although the disease was usually fulminant, 34% of the ATL patients had a subacute or chronic course. Skin involvement and leukemia were prominent in these patients. Hypercalcemia was the chief prognostic determinant. Median survival of hypercalcemic and normocalcemic ATL patients was 13 and 86 weeks (p less than 0.05). Hypercalcemia caused 10 deaths, infections 12, and death was due to tumour progression in 4 patients. Infections were usually due to pyogenic organisms and only 2 patients had systemic opportunistic infections. Six (27%) of 22 chronic lymphocytic leukemic (CLL) patients were HTLV-I-antibody positive.(ABSTRACT TRUNCATED AT 400 WORDS)
How Do We See Art: An Eye-Tracker Study (2011)

We describe the pattern of fixations of subjects looking at figurative and abstract paintings from different artists (Molina, Mondrian, Rembrandt, della Francesca) and at modified versions in which different aspects of these art pieces were altered with simple digital manipulations. We show that the fixations of the subjects followed some general common principles (e.g., being attracted to saliency regions) but with a large variability for the figurative paintings, according to the subject's personal appreciation and knowledge. In particular, we found different gazing patterns depending on whether the subject saw the original or the modified version of the painting first. We conclude that the study of gazing patterns obtained by using the eye-tracker technology gives a useful approach to quantify how subjects observe art.
Phenylene-Bridged Binuclear Organolanthanide Complexes as Catalysts for Intramolecular and Intermolecular Hydroamination (2009)

The phenylene-bridged bimetallic organolanthanide complexes p-bis{Cp′′Ln[N(SiHMe2)2]2}phenylene (p-Ln2; Ln = Y, La, Cp′′ = tetramethylcyclopentadienyl) and m-bis{Cp′′La[N(SiHMe2)2]2}phenylene (m-La2) are investigated for possible Ln···Ln cooperative effects in hydroamination processes. These binuclear organolanthanide complexes efficiently catalyze the intramolecular hydroamination/cyclization of aminoalkenes, aminoalkynes, aminoallenes, and conjugated aminodienes with turnover frequencies as high as 10 h−1 at 60 °C, as well as intermolecular hydroaminations with turnover frequencies as high as 0.4 h−1 at 90 °C. Substrates include those having both compressed and extended junctures between the C−C unsaturation and the −NH2 group, as well as those with multiple −NH2 groups or places of C−C unsaturation. Reactivity trends appear to be dominated by nonbonded repulsive interactions, resulting in catalytic activities following the general trend m-Ln2 < p-Ln2. Organolanthanide amide complexes are also shown to catalyze the prototropic isomerization of alkynes.
TherpoNGene ofXanthomonas campestrispv.vesicatoriaIs Not Required for Pathogenicity (1996)

We have cloned the rpoN region of the pepper and tomato pathogen Xanthomonas campestris pv. vesicatoria to analyze its role in pathogenicity and hrp gene activation. Open reading frame 3 (ORF3) from this region is predicted to encode a protein that is up to 45% identical and 65% similar to previously described RpoN proteins and was shown to be essential for the utilization of nitrate as sole nitrogen source. The X. campestris pv. vesicatoria rpoN gene is, however, not required for pathogenicity and hrp gene expression.
Transport of Spin-Entangled Triplet Excitons Generated by Singlet Fission (2018)

Singlet fission provides a promising route for overcoming the Shockley-Queisser limit in solar cells using organic materials. Despite singlet fission dynamics having been extensively investigated, the transport of the various intermediates in relation to the singlet and triplet states is largely unknown. Here we employ temperature-dependent ultrafast transient absorption microscopy to image the transport of singlet fission intermediates in single crystals of tetracene. These measurements suggest a mobile singlet fission intermediate state at low temperatures, with a diffusion constant of 36 cm<sup>2</sup>s<sup>-1</sup> at 5 K, approaching that for the free singlet excitons, which we attribute to the spin-entangled correlated triplet pair state <sup>1</sup>[TT]. These results indicate that <sup>1</sup>[TT] could transport with a similar mechanism as the bright singlet excitons, which has important implications in designing materials for singlet fission and spintronic applications.
A new reduction process in fast‐atom bombardment mass spectrometry: Substitution of a nitro group by a hydrogen (1993)

Abstract A new example of the resuction phenomenon often observed in fast‐atom bombardment mass spectrometry is described, involving the substitution of a nitro function by a hydrogen atom. This reaction, clearly visible with glycerol as metrix, takes place to only a very limited extent with m‐nitrobenzylalcohol.
A cholestatic pattern predicts major liver‐related outcomes in patients with non‐alcoholic fatty liver disease (2022)

The presence of a cholestatic pattern in patients with NAFLD predicts a higher risk of MALO independently from other features of liver disease.
Diversity and Structure of Bacterial Communitiesin Arctic versus Antarctic PackIce (2003)

A comprehensive assessment of bacterial diversity and community composition in arctic and antarctic pack ice was conducted through cultivation and cultivation-independent molecular techniques. We sequenced 16S rRNA genes from 115 and 87 pure cultures of bacteria isolated from arctic and antarctic pack ice, respectively. Most of the 33 arctic phylotypes were >97% identical to previously described antarctic species or to our own antarctic isolates. At both poles, the alpha- and gamma-proteobacteria and the Cytophaga-Flavobacterium group were the dominant taxonomic bacterial groups identified by cultivation as well as by molecular methods. The analysis of 16S rRNA gene clone libraries from multiple arctic and antarctic pack ice samples revealed a high incidence of closely overlapping 16S rRNA gene clone and isolate sequences. Simultaneous analysis of environmental samples with fluorescence in situ hybridization (FISH) showed that approximately 95% of 4',6'-diamidino-2-phenylindole (DAPI)-stained cells hybridized with the general bacterial probe EUB338. More than 90% of those were further assignable. Approximately 50 and 36% were identified as gamma-proteobacteria in arctic and antarctic samples,respectively. Approximately 25% were identified as alpha-proteobacteria, and 25% were identified as belonging to the Cytophaga-Flavobacterium group. For the quantification of specific members of the sea ice community, new oligonucleotide probes were developed which target the genera Octadecabacter, Glaciecola, Psychrobacter, Marinobacter, Shewanella, and Polaribacter: High FISH detection rates of these groups as well as high viable counts corroborated the overlap of clone and isolate sequences. A terrestrial influence on the arctic pack ice community was suggested by the presence of limnic phylotypes.
Digital RF Processing Techniques for Device Mismatch Tolerant Transmitters in Nanometer-Scale CMOS (2007)

The paper proposed estimation techniques and compensation algorithms against CMOS device variability in an all-digital RF polar transmitter. The transmitter is built using dense and fast digital logic and comprises two converters that transform transmit modulation from digital to RF frequency/phase and amplitude analog domains. The converters built with segmented banks consist of a large number of unit-weighted devices which exhibit a certain level of random and systematic mismatch. The techniques presented are employed in a commercial single-chip GSM/EDGE radio realized in 90 nm CMOS
Bio-Behavioral Sensing (2017)

There is now a significant body of evidence that links human behavior to human health and well-being. In fact, for some behaviors like smoking, the harm to health is so well documented that it has led to public health policies, such as banning smoking inside buildings. Similarly, there is also growing evidence documenting the health benefits of many behaviors, e.g., regular exercise and healthy eating. However, we are only beginning to understand the deep bi-directional connections between human behavior and biology, largely powered by the rapidly increasing body of knowledge from the field of behavioral epigenetics. Since 2000, an explosion of results are unraveling the two-way pathways of how our molecular biology influences our behavior and how our behavior influences our molecular biology
Controlled Rocking Systems for Enhanced Seismic Resilience: State of the Art (2014)

Sustainable development requires attention not only to initial costs, but also to long-term performance. Although common structural systems can be designed economically to protect the lives of users during an earthquake, most cannot easily be designed to be usable after an earthquake. As an alternative, controlled rocking systems are being developed to economically provide not only life safety, but also seismic resilience. This paper gives an overview of the research that has demonstrated the seismic performance of controlled rocking systems in concrete, steel, timber, and masonry. Although most practical implementations have been in low- to mid-rise buildings, recent research has shown that multiple mechanisms could make controlled rocking systems competitive for taller structures.
Modellansätze für die digitale Fabrik (2010)

Zusammenfassung Die digitale Fabrik ist ein Konzept, das schon viele Jahre Ansporn für die verschiedensten Initiativen z. B. des digitalen Engineerings, der Normenreihe IEC 62264 zur Integration von Unternehmensführungs- und Leitsystemen oder für eBusiness-Anwendungen ist. Dies führt zur Existenz vieler verschiedenen Herangehensweisen und Modellansätze. Die Diskussion zu Ausprägung und Anzahl von relevanten Modellen und vor allem deren Modellgrundlagen für die einheitliche Betrachtung einer gesamten digitalen Fabrik ist noch offen.
