Tenant-ID: Tagging Tenant Assets in Cloud Environments (2013)

Cloud Computing facilitates the new generation of IT and the provisioning of services by introducing virtualization concepts throughout the network. Multi-tenancy introduces the capability to share cloud assets among service users. Service providers currently lack innovative means to enable true multi-tenancy in a cloud environment. There is an urgent need for technologies that introduce tenant security, traffic identification and tenant separation for better billing and fairness. This paper introduces a technology that tackles all these requirements by defining the concept of a Tenant-ID that is incorporated into the OSI Layer 2 frame header. We outline the concept of Tenant-IDs, the adapted 802.1q header and a way to automatically configure tenants via Cloud automation tools and software-defined networking approaches. The paper concludes by outlining interoperability to relevant layer-2 protocols and by introducing use-cases benefiting from the Tenant-ID concept.
Progression From IgD + IgM + to Isotype-Switched B Cells Is Site Specific during Coronavirus-Induced Encephalomyelitis (2014)

Acute and chronic human CNS infections are associated with an accumulation of heterogeneous B cell subsets; however, their influence on viral load and disease is unclear. Using a glia-tropic coronavirus model, we demonstrate that the accumulation of B cells ranging from early-activated to isotype-switched differentiation stages is both temporally and spatially orchestrated. Acutely infected brains and spinal cords indiscriminately recruit a homogeneous population of early-activated B cells, which is progressively replaced by diverse, more differentiated subsets. The latter process is accelerated by elevated proinflammatory responses associated with viral persistence. The results imply that early-recruited B cells do not have antiviral function but may contribute to the inflammatory environment or act as antigen-presenting cells. Moreover, CNS viral persistence is a driving force promoting differentiated B cells with protective potential.
Adaptive individual-cylinder thermal state control using intake air heating for a GDCI engine (2023)

A system for a multi-cylinder compression ignition engine includes a plurality of heaters, at least one heater per cylinder, with each heater configured to heat air introduced into a cylinder. Independent control of the heaters is provided on a cylinder-by-cylinder basis. A combustion parameter is determined for combustion in each cylinder of the engine, and control of the heater for that cylinder is based on the value of the combustion parameter for combustion in that cylinder. A method for influencing combustion in a multi-cylinder compression ignition engine, including determining a combustion parameter for combustion taking place in a cylinder of the engine and controlling a heater configured to heat air introduced into that cylinder, is also provided.
Analysis of Scattering Sites in Transparent Magnesium Aluminate Spinel (2008)

Scattering sites greatly degrade the transmission of magnesium aluminate spinel. It appears that some of the scattering sites are caused by reactions with the LiF traditionally used as a sintering aid. LiF is used to etch spinet particles during the hot pressing process. The LiF was found to react with the aluminum in the spinel structure thereby leaving magnesium rich regions behind that do not sinter well and result in opaque regions in the otherwise transparent matrix. Avoiding the conditions where the reaction is most aggressive allows the densification of spinel that transmits throughout the entire transmission range at 100% of the theoretical bulk value.
An orbital-overlap model for minimal work functions of cesiated metal surfaces (2012)

We introduce a model for the effect of cesium adsorbates on the work function of transition metal surfaces. The model builds on the classical point-dipole equation by adding exponential terms that characterize the degree of orbital overlap between the 6s states of neighboring cesium adsorbates and its effect on the strength and orientation of electric dipoles along the adsorbate-substrate interface. The new model improves upon earlier models in terms of agreement with the work function-coverage curves obtained via first-principles calculations based on density functional theory. All the cesiated metal surfaces have optimal coverages between 0.6 and 0.8 monolayers, in accordance with experimental data. Of all the cesiated metal surfaces that we have considered, tungsten has the lowest minimum work function, also in accordance with experiments.
Thin-Layer Chromatography/Desorption Electrospray Ionization Mass Spectrometry:  Investigation of Goldenseal Alkaloids (2007)

Desorption electrospray ionization mass spectrometry was investigated as a means to qualitatively identify and to quantify analytes directly from developed normal-phase thin-layer chromatography plates. The atmospheric sampling capillary of a commercial ion trap mass spectrometer was extended to permit sampling and ionization of analytes in bands separated on intact TLC plates (up to 10 cmx10 cm). A surface positioning software package and the appropriate hardware enabled computer-controlled surface scanning along the length of development lanes or at fixed Rf value across the plates versus the stationary desorption electrospray emitter. Goldenseal (Hydrastis canadensis) and related alkaloids and commercial dietary supplements were used as standards and samples. Alkaloid standards and samples were spotted and separated on aluminum- or glass-backed plates using established literature methods. The mass spectral signal levels as a function of desorption spray solvent were investigated with acetonitrile proving superior to methanol. The detection levels (approximately 5 ng each or 14-28 pmol) in mass spectral full-scan mode were determined statistically from the calibration curves (2.5-100 pmol) for the standards berberine, palmatine, and hydrastinine spotted as a mixture and separated on the plates. Qualitative screening of the major alkaloids present in six different over-the-counter "goldenseal" dietary supplements was accomplished by obtaining full-scan mass spectra during surface scans along the development lane in the direction of increasing Rf value. In one sample, alkaloids were detected that strongly suggested the presence of at least one additional herb undeclared on the product label. These same data indicated the misidentification of one of the alkaloids in the TLC literature. Quantities of the alkaloids present in two of the samples determined using the mass spectral data were in reasonable agreement with the label values, indicating the quantitative ability of the method. The advantage of mass spectral measurements in identifying and quantifying materials within overlapping bands and in providing positive identification for even minor species in a mixture was also demonstrated.
Vitamin D Does Not Play a Functional Role in Adipose Tissue Development in Rodent Models (2017)

Data indicate that vitamin D does not play a fundamental role in adipogenesis because vitamin D does not affect fetal adipogenesis. Moreover, the smaller adipocytes observed in adult Vdr-KO mice are presumably caused by an increased energy expenditure due to alopecia.
Influence of Yb3+ions on the optical properties of double-doped Er,Yb : CaF2crystals (2011)

Judd–Ofelt (J–O) analysis is used to estimate the magnitude of the forced (4f–4f) transition probabilities of Er3+ ions in double-doped (Er,Yb) : CaF2 crystals. The studied crystals were grown in our crystal research laboratory using the vertical Bridgman method. The J–O intensity parameters Ω2, Ω4 and Ω6 were calculated from the optical absorption spectra. These parameters were then used to evaluate the spontaneous transition probability, the line strength, the branching ratio and the radiative lifetime. The obtained radiative decay rates were compared with the luminescence spectra.
Small-Dose India Ink Tattooing for Preoperative Localization of Colorectal Tumor (2010)

Small-dose tattooing with sterile India ink using a saline test-injection method is effective for tumor localization.
Improvement of tracking accuracy and stability by recursive image processing in real-time tumor-tracking radiotherapy system (2012)

In the real-time tumor-tracking radiotherapy (RTRT) system, the fiducial markers are inserted in or near the target tumor in order monitor the respiratory-induced motion of tumors. During radiation treatment, the markers are detected by continuous fluoroscopy operated at 30 frames/sec. The marker position is determined by means of a template pattern matching technique which is based on the normalized cross correlation. With high tube voltage, large current and long exposure, the fiducial marker will be recognized accurately, however, the radiation dose due to X-ray fluoroscopy increases. On the other hand, by decreasing the fluoroscopy parameter settings, the fiducial marker could be lost because the effect of statistical noise is increased. In the respiratory-gated radiotherapy, the error of the image guidance will induce the reduction of the irradiation efficiency and accuracy. In order to track the marker stably and accurately in low dose fluoroscopy, we propose the application of a recursive filter. The effectiveness of the image processing is investigated by tracking the static marker and the dynamic marker. The results suggest that the stability and the accuracy of the marker tracking can be improved by applying the recursive image filter in low dose imaging.
Prevalence ofCryptococcus neoformansvar.neoformans(Serotype D) andCryptococcus neoformansvar.grubii(Serotype A) Isolates in New York City (2000)

Analysis of 40 New York City Cryptococcus neoformans isolates revealed that 39 were typeable, of which 85 and 12.5% were Cryptococcus neoformans var. grubii (serotype A) and Cryptococcus neoformans var. neoformans (serotype D), respectively. The prevalence of serotype D isolates in New York City appears to be significantly higher than indicated by previous studies of North American isolates.
Surrogate Modelling with Sequential Design for Expensive Simulation Applications (2017)

The computational demands of virtual experiments for modern product development processes can get out of control due to fine resolution and detail incorporation in simulation packages. These demands for appropriate approximation strategies and reliable selection of evaluations to keep the amount of required evaluations were limited, without compromising on quality and requirements specified upfront. Surrogate models provide an appealing data‐driven strategy to accomplish these goals for applications including design space exploration, optimization, visualization or sensitivity analysis. Extended with sequential design, satisfactory solutions can be identified quickly, greatly motivating the adoption of this technology into the design process.
Questionnaire-Based Diagnosis of REM Sleep Behavior Disorder in Parkinson's Disease (S03.004) (2013)

A Highly Active Catalyst for Suzuki–Miyaura Cross‐Coupling Reactions of Heteroaryl Compounds (2006)

Unprecedented activity: Catalysts derived from Pd and bulky dialkylphosphinobiaryl ligands are shown to be highly stable and active in Suzuki–Miyaura reactions of heteroaryl halides and heteroaryl boronic acids/esters (e.g., 3- or 4-pyridine, indole, and N-protected pyrrole derivatives). Furthermore, this catalyst system is not inhibited by the presence of highly basic aminopyridines or aminopyrimidines.

Facile Synthesis of Photoluminescent ZnS and ZnSe Nanopowders (2008)

The solid state thermal, one pot, efficient chemical reaction between Zn and S or Se elements in a closed reactor at 650 degrees C/60 min under their autogenic pressure in an inert atmosphere yielded luminescent ZnS and ZnSe semiconducting nanopowders (NPs). Scanning and Transmission electron microscopy measurements confirmed the size and shape of the as formed ZnS and ZnSe NPs. The wide size distributions of ZnS and ZnSe NPs are confirmed by UV-vis and TEM measurements. The crystalline wurtzite phase of ZnS and face centered cubic phase of ZnSe NPs is revealed from XRD and HR-TEM measurements. The obtained Raman scattering bands also supports the formation of pure ZnS and ZnSe phases. At room temperature, a strong visible green emission centered at approximately 525 nm is measured for ZnS, while ZnSe NPs showed a broad red emission band extending from 550 to 760 nm. The putative reaction mechanism is based on the low melting and boiling points of reactants (Zn, S and Se) under their autogenic pressure in an inert atmosphere.
The future of sensory substitution, addition, and expansion via haptic devices (2023)

Haptic devices use the sense of touch to transmit information to the nervous system. As an example, a sound-to-touch device processes auditory information and sends it to the brain via patterns of vibration on the skin for people who have lost hearing. We here summarize the current directions of such research and draw upon examples in industry and academia. Such devices can be used for sensory substitution (replacing a lost sense, such as hearing or vision), sensory expansion (widening an existing sensory experience, such as detecting electromagnetic radiation outside the visible light spectrum), and sensory addition (providing a novel sense, such as magnetoreception). We review the relevant literature, the current status, and possible directions for the future of sensory manipulation using non-invasive haptic devices.
An n‐Type Conjugated Oligoelectrolyte Mimics Transmembrane Electron Transport Proteins for Enhanced Microbial Electrosynthesis (2023)

Interfacing bacteria as biocatalysts with an electrode provides the basis for emerging bioelectrochemical systems that enable sustainable energy interconversion between electrical and chemical energy. Electron transfer rates at the abiotic-biotic interface are, however, often limited by poor electrical contacts and the intrinsically insulating cell membranes. Herein, we report the first example of an n-type redox-active conjugated oligoelectrolyte, namely COE-NDI, which spontaneously intercalates into cell membranes and mimics the function of endogenous transmembrane electron transport proteins. The incorporation of COE-NDI into Shewanella oneidensis MR-1 cells amplifies current uptake from the electrode by 4-fold, resulting in the enhanced bio-electroreduction of fumarate to succinate. Moreover, COE-NDI can serve as a "protein prosthetic" to rescue current uptake in non-electrogenic knockout mutants.

Signature-embedding in printed documents for security and forensic applications (2004)

Despite the increase in email and other forms of digital communication, the use of printed documents continues to increase every year. Many types of printed documents need to be "secure" or traceable to the printer that was used to print them. Examples of these include identity documents (e.g. passports) and documents used to commit a crime. Traditional protection methods such as special inks, security threads, or holograms, can be cost prohibitive. The goals of our work are to securely print and trace documents on low cost consumer printers such as inkjet and electrophotographic (laser) printers. We will accomplish this through the use of intrinsic and extrinsic features obtained from modelling the printing process. Specifically we show that the banding artifact in the EP print process can be viewed as an intrinsic feature of the printer used to identify both the model and make of the device. Methods for measuring and extracting the banding signals from documents are presented. The use of banding as an extrinsic feature is also explored.
AI-Based Digital Predistortion for IQ Mach-Zehnder Modulators (2019)

A low-complexity Al-based digital predistortion technique is proposed. It compensates nonlinearities of Mach-Zehnder modulators in high power optical transmitters. A link budget of 19.1dB for a 400ZR system over an unamplified 40km-SSFM link was achieved.
A SAR Prediction Concept for Parallel Transmission MRI (2011)

The speci c absorption rate (SAR) is a limiting factor in higheld MR. SAR estimation is typically performed by numerical simulations using generic human body models. However, SAR concepts for single-channel RF transmission cannot be directly applied for multi-channel systems. In this study, a novel and comprehensive SAR prediction concept for parallel RF transmission MRI is presented, based on pre-calculated B1 and electric elds obtained from EM simulations of multiple numerical body models. The application of so-called Q-matrices and further computational optimizations allow for real-time SAR prediction prior to scanning. This SAR prediction concept was fully integrated into an 8-channel whole body MRI system and facilitates selection of di erent body models and body positions. Experimental validation of the global SAR in phantoms showed good qualitative and quantitative agreement. Also an initial in vivo validation showed good qualitative agreement between simulated and measured B1. The feasibility and practicability of this SAR prediction concept was shown, paving the way for safe parallel RF transmission in higheld MR.
[Demonstration of an engagement process towards cell death by apoptosis in lymphocytes of HIV infected patients]. (1991)

Peripheral blood lymphocytes from AIDS patients or from infected asymptomatic individuals display a rapid loss of viability upon culture in a survival medium. Cellular death occurs following endonucleosomal DNA fragmentation (apoptosis), which is preceeded by chromatin condensation and lower staining with orange acridine. This phenomenon is accelerated by compounds known to activate lymphocytes (such as ionophores) and is partly or entirely suppressed by addition of a cytokine crude preparation, enriched in IL2. All together, these results suggest that in vivo a significant fraction of patients' lymphocytes is engaged towards a preapoptosis process resulting from abnormal activation.
<title>Negative DUV photoresist for 16Mb-DRAM production and future generations</title> (1993)

This paper discusses a new negative tone aqueous base developable photoresist that has demonstrated excellent sub-half micron resolution with commercially available DUV (deep ultraviolet) exposure systems. This system which consists of a phenolic resin (pHOST), a glycoluril crosslinker (TMMGU), and a triflic acid generating material is currently in use for the manufacturing of 16 M b-DRAM and related CMOS logic technology. We provide supporting manufacturing data relating to our experiences with this program, along with the benefits realized by the implementation of a negative tone photoresist system.
Alkaline O2 reduction on oxide-derived Au: high activity and 4e− selectivity without (100) facets (2014)

Gold films produced from gold oxide precursors ("oxide-derived Au") were compared to polyhedral Au nanoparticles for electrocatalytic alkaline O2 reduction. Despite having no detectable abundance of (100) facets, oxide-derived Au exhibited 4e(-) selectivity and surface-area-normalized activity that rivaled cubic Au nanoparticles with high (100) abundance. The activity of oxide-derived Au likely arises from active sites at the surface terminations of defects that are trapped during gold oxide reduction.
High-performance self-aligned SiGeC HBT with selectively grown Si/sub 1-x-yGe/sub x/C/sub y/ base by UHV/CVD (2003)

Si/sub 1-x-y/Ge/sub x/C/sub y/ selective epitaxial growth (SEG) was performed by cold-wall, ultrahigh-vacuum chemical vapor deposition, and the effects of incorporating C on the crystallinity of Si/sub 1-x-y/Ge/sub x/C/sub y/ layers and the performance of a self-aligned SiGeC heterojunction bipolar transistor (HBT) were evaluated. A Si/sub 1-x-y/Ge/sub x/C/sub y/ layer with good crystallinity was obtained by optimizing the growth conditions. Device performance was significantly improved by incorporating C, as a result of applying Si/sub 1-x-y/Ge/sub x/C/sub y/ SEG to form the base of a self-aligned HBT. Fluctuations in device performance were suppressed by alleviating the lattice strain. Furthermore, since the B out diffusion could be suppressed by incorporating C, the cutoff frequency was able to be increased with almost the same base resistance. A maximum oscillation frequency of 174 GHz and an emitter coupled logic gate-delay time of 5.65 ps were obtained at a C content of 0.4%, which shows promise for future ultrahigh-speed communication systems.
aAPC immunization activates low affinity T cells for treatment of tumors (B147) (2007)

Abstract The development of effective anti-tumor immune responses is normally constrained by low affinity tumor specific CTL which are unable to eradicate the tumor. Strategies to rescue anti-tumor activity of low affinity melanoma-specific CTL in vivo might improve immunotherapy effectiveness. To boost the in vivo efficiency of low affinity CTL clone we immunized mice with artificial Antigen Presenting Cells (aAPC), made by covalent coupling of pepMHC-Ig dimer and B7.1-Ig molecules to magnetic beads, in a lung metastatic tumor model. Systemic administration of aAPC resulted in the complete tumor eradication and was associated with proliferation of adoptively transferred low affinity CTL clones. In vitro studies showed that aAPC, in contrast to tumor cells effectively stimulated cytokine release and TCR down-regulation, explaining the efficient in vivo activation of low affinity CTL. Thus, aAPC represent a novel adjuvant for cancer immunotherapy.
Evaluation of Soluble Junctional Adhesion Molecule-A as a Biomarker of Human Brain Endothelial Barrier Breakdown (2010)

Soluble JAM-A was not suited as a biomarker of BBB breakdown in our hands. The unexpected non-inducibility of sJAM-A release at the human BBB might contribute to a particular resistance of brain EC to inflammatory stimuli, protecting the CNS compartment.
