Precise Deposition of Carbon Nanotube Bundles by Inkjet-Printing on a CMOS-Compatible Platform (2022)

Carbon nanotubes (CNTs) are ultimately small structures, attractive for future nanoelectronics. CNT-bundles on Si nanostructures can offer an alternative pathway to build hybrid CMOS-compatible devices. To develop a simple method of using such CNT-bundles as transistor channels, we fabricated semiconductor single-walled CNT field-effect transistors using inkjet printing on a CMOS-compatible platform. We investigated a method of producing stable CNT solutions without surfactants, allowing for CNT debundling and dispersion. An inkjet-printing system disperses CNT-networks with ultimately low density (down to discrete CNT-bundles) in Al source-drain gaps of transistors. Despite the small number of networks and random positions, such CNT-bundles provide paths to the flow current. For enhanced controllability, we also demonstrate the manipulation of CNT-networks using an AFM technique.
FDG-PET/CT for driveline infection in a patient with implantable left ventricular assist device (2015)

The patient in this case was a 41-year-old man who had undergone implantable left ventricular assist device (LVAD) implantation (DuraHeart, Terumo, Japan) 8 months before due to refractory heart failure caused by hypertensive heart disease. The patient had suffered from epigastric pain for 1 week, and a plain computed tomography (CT) scan did not show any causal diseases. As it …
Qa-region class I gene expression: identification of a second class I gene, Q9, encoding a Qa-2 polypeptide. (1988)

A feature of the expression of the tissue-specific class I antigen Qa-2 is the quantitative variation among mouse strains. Recently, the class I gene Q7 has been shown to encode a protein product that is biochemically indistinguishable from the lymphocyte-bound Qa-2 molecule. Utilizing gene transfection, we have identified a second Qa-2 subregion class I gene (Q9), in H-2b mice, which encodes a polypeptide biochemically similar to the Q7 and the Qa-2 polypeptides. Furthermore, we have observed that cell lines transfected with the allelic forms of the Q7 gene from C57BL/10 (Qa-2hi) or BALB/C (Qa-2low) display quantitative differences in cell-surface expression. Based on these studies, we suggest that gene dosage and allele-specific variation in cell-surface expression contribute to the strain-specific variation in the levels of Qa-2 antigen expression.
A Novel 3D DRAM Memory Cube Architecture for Space Applications (2018)

The first mainstream products in 3D IC design are memory devices where multiple memory tiers are horizontally integrated to offer manifold improvements compared with their 2D counterparts. Unfortunately, none of these existing 3D memory cubes are ready for harsh space environments. This paper presents a new memory cube architecture for space, based on vertical integration of Commercial-Off-The-Shelf (COTS), 3D stacked, DRAM memory devices with a custom Radiation-Hardened-By-Design (RHBD) controller offering high memory capacity, robust reliability and low latency. Validation and evaluation of the ASIC controller will be conducted prior to tape-out on a custom FPGA-based emulator platform integrating the 3D-stack.
Short-Term Prediction of Silicon Content in Pig Iron (1994)

Prediction and control of the silicon content of pig iron is an important but difficult task in the operation of the blast furnace process. A model for time-series modeling of the silicon content in small- or medium-sized blast furnaces is presented. The model makes use of recent measurement information from the furnace and considers the dynamics of the furnace hearth in a simplified way. Based on ladle-wise chemical analyses, which provide information about the short-term behavior of the silicon content, the parameters of an autoregressive vector model with irregularly observed data are estimated. A practically continuous estimate of the silicon content is obtained, which may act as an indicator for the operator, who has to decide about possible control actions to be taken. The model also predicts the evolution of the silicon content during the next few hours. Résumé Prédire et contrôler la teneur en silicium des saumons de fonte est une tâche importante mais difficiledans le processus d'opération des haut-fourneaux. On présente un modèle pour modéliser la teneur en silicium des petits et moyens hauts-fourneaux par des suites fonction du temps. Le modèle utilise des infonnations récentes mesurées dans les hauts-fourneaux et traite, de façon simplifiee, la dynamique du creur des hauts-fourneaux. À partir d'analyses chimiques échelonnées qui fournissent des informations sur l'évolution à court terme de la teneur en silicium, on estime les parametres d'un modèle vectoriel autorégressif avec des données observées irregulièrement. On obtient une estimation quasi continue de la teneur en silicium qui pourrait jouer le rôle d'indicateur pour l'opérateur qui doit décider de possibles actions de contrôles à prendre. Le modèle prédit également l'évolution de la teneur en silicium au cours des heures suivantes.
A measurement of material in the ATLAS tracker using secondary hadronic interactions in 7 TeVppcollisions (2016)

Knowledge of the material in the ATLAS inner tracking detector is crucial in understanding&#13;\nthe reconstruction of charged-particle tracks, the performance of algorithms that identify&#13;\njets containing b-hadrons and is also essential to reduce background in searches for exotic particles&#13;\nthat can decay within the inner detector volume. Interactions of primary hadrons produced in pp&#13;\ncollisions with the material in the inner detector are used to map the location and amount of this&#13;\nmaterial. The hadronic interactions of primary particles may result in secondary vertices, which in&#13;\nthis analysis are reconstructed by an inclusive vertex-finding algorithm. Data were collected using&#13;\nminimum-bias triggers by the ATLAS detector operating at the LHC during 2010 at centre-of-mass&#13;\nenergy p&#13;\ns = 7 TeV, and correspond to an integrated luminosity of 19 nb􀀀���1. Kinematic properties&#13;\nof these secondary vertices are used to study the validity of the modelling of hadronic interactions&#13;\nin simulation. Secondary-vertex yields are compared between data and simulation over a volume&#13;\nof about 0.7m3 around the interaction point, and agreement is found within overall uncertainties.
Efflux pumps as antimicrobial resistance mechanisms (2007)

Antibiotic resistance continues to hamper antimicrobial chemotherapy of infectious disease, and while biocide resistance outside of the laboratory is as yet unrealized, in vitro and in vivo episodes of reduced biocide susceptibility are not uncommon. Efflux mechanisms, both drug-specific and multidrug, are important determinants of intrinsic and/or acquired resistance to these antimicrobials in important human pathogens. Multidrug efflux mechanisms are generally chromosome-encoded, with their expression typically resultant from mutations in regulatory genes, while drug-specific efflux mechanisms are encoded by mobile genetic elements whose acquisition is sufficient for resistance. While it has been suggested that drug-specific efflux systems originated from efflux determinants of self-protection in antibiotic-producing Actinomycetes, chromosomal multidrug efflux determinants, at least in Gram-negative bacteria, are appreciated as having an intended housekeeping function unrelated to drug export and resistance. Thus, it will be important to elucidate the intended natural function of these efflux mechanisms in order, for example, to anticipate environmental conditions or circumstances that might promote their expression and, so, compromise antimicrobial chemotherapy. Given the clinical significance of antimicrobial exporters, it is clear that efflux must be considered in formulating strategies for treatment of drug-resistant infections, both in the development of new agents, for example, less impacted by efflux or in targeting efflux directly with efflux inhibitors.
Sampling rate reduction for 60 GHz UWB communication using compressive sensing (2009)

60 GHz ultra wide-band (UWB) communication is an emerging technology for high speed short range communications. However, the requirement of high-speed sampling increases the cost of receiver circuitry such as analog-to-digital converter (ADC). In this paper, we propose to use a compressive sensing framework to achieve a significant reduction of sampling rate. The basic idea is based on the observation that the received signals are sparse in the time domain due to the limited multipath effects at 60 GHz wireless transmission. According to the theory of compressive sensing, by carefully designing the sensing scheme, sub-Nyquist rate sampling of the sparse signal still enables exact recovery with very high probability. We discuss an implementation for a low-speed A/D converter for 60 GHz UWB received signal. Moreover, we analyze the bit error rate (BER) performance for BPSK modulation under RAKE reception. Simulation results show that in the single antenna pair system model, sampling rate can be reduced to 2.2% with 0.3dB loss of BER performance if the input sparsity is less than 1%. Consequently, the implementation cost of ADC is significantly reduced.
Comparison of the imbalance effects in direct conversion transmitters and receivers (2011)

Although direct conversion transmitters and receivers share the same structure certain differences in their behavior can be found. These differences result in diverse performance limitations. This paper derives a linear model of direct conversion transmitters and receivers. Based on this model methods to extract the frequency dependent characteristics are introduced and compensators are suggested. By applying these techniques to a custom transmitter and receiver setup the achievable imbalance suppressions are demonstrated and the derived performance improvements are compared.
Depositional Architecture of Glacigenic Regressive Deltas (2012)

Dedicated Glaciations In this paper we will document the stratigraphic evolution, internal facies architecture and geomorphology of regressive glacigenic deltas, controlled by rapid high-amplitude base-level change. These systems are excellent field example to test the effect of high-amplitude base-level change on glacigenic delta systems, because subsidence, compaction, wave or tides did not play a major role. A large data set, including outcrop data, borehole data and high-resolution shear-wave seismic sections can resolve architectural elements in the range of metres and bridge the common gap between outcrop and standard industrial compression wave seismic data. The objective of this work is to provide a synthesis of the stratigraphic architecture of regressive deltas, giving new insights into the controls on delta building and erosion processes. The emphasis is placed on the sedimentary facies associations, the correlation of seismic facies with boreholes and outcrops and the analysis of the larger scale stacking pattern of architectural elements. A new depositional model summarizing facies features, depositional processes and architectures is proposed that may add to the sequence stratigraphic interpretation of steep glacigenic delta systems, controlled by rapid base-level change.
SecureAngle (2010)

Wireless local area networks play an important role in our everyday lives, at the workplace and at home. However, wireless networks are also relatively vulnerable: physically located off-premises, attackers can circumvent wireless security protocols such as WEP, WPA, and even to some extent WPA2, presenting a security risk to the entire network. To address this problem, we propose SecureAngle , a system designed to operate alongside existing wireless security protocols, adding defense in depth. SecureAngle employs multiantenna APs to profile the directions at which a client's signal arrives, using this angle-of-arrival information to construct unique signatures that identify each client. With these signatures, we are currently investigating how a SecureAngle enabled AP can enable a "virtual fence" that drops frames injected into the network from a client physically located outside a building, and how a SecureAngle-enabled AP can prevent malicious parties from spoofing the link-layer address of legitimate clients.
Enrichment of inflammatory mediators in the synovial fluid is associated with slower progression of mild to moderate osteoarthritis in the porcine knee. (2021)

The roles that cytokines and matrix metalloproteinases play in the onset and progression of posttraumatic osteoarthritis (PTOA) remain a topic of debate. The study objective was to evaluate the concentrations of these inflammatory mediators during the development of mild to moderate PTOA in the porcine anterior cruciate ligament (ACL) surgical model. We hypothesized that there would be more animals with detectable mediators in the pigs that develop moderate PTOA (those receiving ACL reconstruction or untreated ACL transection) compared to those that develop mild PTOA (those receiving scaffold-enhanced ACL repair). 36 Yucatan minipigs underwent ACL transection and were randomized to: 1) no further treatment, 2) ACL reconstruction, or 3) scaffold-enhanced ACL repair. Synovial fluid samples were obtained pre-operatively, and at 1, 4, 12, 26 and 52 weeks post-operatively. The concentrations of inflammatory mediator in the synovial fluid samples were evaluated via multiplex assay. Macroscopic cartilage assessments were performed following euthanasia at 52 weeks. As found in prior studies, the repair group had significantly less cartilage damage than either the ACL transected or ACL reconstruction groups (P<.03). The presence and concentrations of the biomarkers were influenced by surgical group and time. In general, the concentrations of inflammatory mediators were higher in the repair group, which exhibited less cartilage damage than the other two treatment groups. While this finding disproved the hypotheses, these data suggest that the metabolic activity of the joints exhibiting less cartilage damage remained higher over the 52-week period than those that did not.
Calculations of the electric field dependent far-infrared absorption spectra in InAs/AlGaSb quantum wells (1989)

Excitonic and band-to-band absorption spectra are calculated for vertical incident radiation for the InAs/AlGaSb multiple quantum well structures. Due to the special band lineup of this heterostructure, the absorption spectra can be tailored to respond in far infrared. The electric field dependence of the spectra shows blue shift and enhanced absorption in contrast to the situation in type I quantum wells. Applications to far infrared detectors are discussed.
Biofilm-associated Mycobacterium abscessus cells have altered antibiotic tolerance and surface glycolipids in Artificial Cystic Fibrosis Sputum Media (2018)

Abstract Mycobacterium abscessus ( Mab ) is a biofilm-forming, multi-drug resistant, non-tuberculous mycobacterial (NTM) pathogen increasingly found in Cystic Fibrosis patients. Antibiotic treatment for these infections is often unsuccessful, partly due to Mab ’s high intrinsic antibiotic resistance. It is not clear whether antibiotic tolerance caused by biofilm formation also contributes to poor treatment outcomes. We studied the surface glycolipids and antibiotic tolerance of Mab biofilms grown in Artificial Cystic Fibrosis Sputum (ACFS) media in order to determine how they are affected by nutrient conditions that mimic infection. We found that Mab displays more of the virulence lipid trehalose dimycolate when grown in ACFS compared to standard lab media. In ACFS media, biofilm-associated cells are more antibiotic tolerant than planktonic cells in the same well. This contrasts with standard lab medias, where biofilm and planktonic cells are both highly antibiotic tolerant. These results indicate that Mab cell physiology in biofilms depends on environmental factors, and that nutrient conditions found within Cystic Fibrosis infections could contribute to both increased virulence and antibiotic tolerance.
Fiber- vs. Microwave-based 5G Transport: a Total Cost of Ownership Analysis (2022)

&lt;p&gt;Answering a key question from operators, the paper compares the techno-economic performance of fiber and microwave-based 5G transport deployments using vendor's inventories and real-life field deployment scenarios. Results highlight how microwave gains vary based on the geo-types, the fiber trenching, and microwave equipment costs.&lt;/p&gt;
Human breast cancer: correlation study between HER-2/neu amplification and prognostic factors in an unselected population. (1993)

In 199 breast cancers, HER-2/neu amplification was analyzed by Southern blotting (149 cases) and by slot blotting (149 cases), with 99 cases studied using both techniques. There were 18.8% amplified tumors (> or = 2 copies) by Southern blotting and 15.4% by slot blotting. The difference in the percentages of amplified tumors was not statistically significant (p = 0.44). There was a correlation between HER-2/neu amplification and the SBR grade (p = 0.046): this correlation relied on the absence of amplification in the GI tumors. In a subset study, the negativity of the progesterone receptor content was correlated with HER-2/neu amplification in the node positive (p = 0.02), the pre-menopausal (p = 0.04) and the pre-menopausal node positive (p = 0.002) patients. In the literature as in our results, amplification appears to be correlated with poor prognostic factors. However, in a subgroup with most of the favorable prognostic factors: positive estrogen and progesterone receptor contents and node negativity, the frequency of amplified tumors (19.4%, n = 67) was the same as that observed in the whole group (16.6%, n = 199). This result may suggest that the HER-2/neu amplification could act as an independent prognostic factor.
Antioxidizing component, musizin, inrumex japonicus houtt (1991)

Abstract A substance with antioxidant properties was obtained from the hexane extract of roots of Rumex japonicus Houtt. The active component of the hexane extract was isolated and characterized as 2‐acetyl‐1,8‐dihydroxy‐3‐methyl naphthalene, trivially named musizin (MUS). The antioxidant activities of MUS in six types of fats and oils were higher than that of butyl hydroxyanisole (BHA) and δ‐tocopherol (δ‐TOC). Together, TOC and MUS have a synergistic effect, because comparable amounts of either had lower antioxidant activity than various combinations of the two antioxidants. When we studied the antioxidant properties of a mixture of MUS and δ‐TOC with methyl linoleate (MeLH), we found that the rates of destruction of the two antioxidants were comparable, but that their destruction occurred sequentially, with MUS first followed by δ‐TOC, after which the oxidation of MeLH quickly occurred. Comparison of the antioxidant activity of MUS and its analogs suggests that only one of the two hydroxyl groups in MUS is involved in its antioxidant activit. Intermolecular hydrogen bonding may be involved.
Some properties of composite resins cured by pulsed blue laser (1999)

The purpose of the study was to analyse some properties of composite resin samples cured by pulsed laser in comparison with standard halogen light. Three bybrid and three microfilled commercial composite materials were polymerized in the experimental conditions using an excimer laser pumped dye laser (XeCl Lambda Physik LPX 100/LPD 3002) and a standard curing unit (Heliolux GTE). The samples were spectroscopically analysed (FTIR) for the degree of conversion, scanning electron microscopy (SEM) was performed for characterising the structure of the material, and volumetric shrinkage behaviour was tested using density bottle method. Statistical analysis of the data (ANOVA p<0.05) shoes that the degree of conversion values obtained by excimer laser was significantly higher for all the materials and shades tested while the polymerization shrinkage values were significantly lower compared with the conventional curing unit. Those results are clinically very important in situations whenever close approximation of the light curing tip to the composite surface is impossible. The monochromatic pulsed dye laser set at 468 nm allows high penetration into the sample and the nature of the pulse allows homogeneous high quality curing with decreased shrinkage of the composite resin. The sensitivity of the tooth after the placement of direct composite restoration is mainly connected with the polymerization contraction. Adhesive and cohesive fractures appear in dentin, hybrid layer and material itself. The amount of volumetric increase is in accordance with the degree of cure, the type of composite material and the nature of the activating light.
The Laser Approach to Blepharoplasty (1988)

A new technique for upper and lower eyelid blepharoplasty, combining the advantages of the transconjunctival approach with those of the CO2 laser, is described. The use of the CO2 laser as the only cutting tool eliminates many of the most common and the most serious complications of blepharoplasty attributable to hemorrhage and hematoma. The transconjunctival approach yields superior cosmetic results to those of the more commonly performed traditional techniques, which sometimes results in unacceptable lower eyelid scars and/or lower eyelid retraction. Patient rehabilitation to normal activity is rapid because of decreased bruising and swelling. The laser procedure is well suited to the office-based laser surgical practice, but requires a high degree of skill in CO2 laser excisional surgery. In the hands of the inexperienced operator, new and serious complications may occur.
