Functionalized Au22 Clusters: Synthesis, Characterization, and Patterning (2009)

We synthesized fluorescent, porphyrin-anchored, Au(22) clusters in a single step, starting from well-characterized Au(25) clusters protected with glutathione (-SG) by a combined core reduction/ligand exchange protocol, at a liquid-liquid interface. The prepared cluster was characterized by UV/vis, photoluminescence, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy, elemental analysis, and matrix-assisted laser desorption ionization mass spectrometry. The absence of a 672 nm intraband transition of Au(25) and the simultaneous emergence of new characteristic peaks at 520 and 635 nm indicate the formation of the Au(22) core. An increase in the binding energy of 0.4 eV in Au 4f core-level peaks confirmed the presence of a reduced core size. Quantitative XPS confirmed the Au/S ratio. The presence of a free base, tetraphenylporphyrin (H(2)TPPOAS-), on the Au(22) core was confirmed by fluorimetric titrations with Cu(2+) and Zn(2+) ions. From all of these, the composition of the cluster was determined to be Au(22)[(-SG)(15)(-SAOPPTH(2))(2)], which was supported by mass spectrometry and elemental analysis. We utilized the fluorescence nature of these water-soluble clusters for the fabrication of fluorescent patterns by soft lithography. The patterns were studied using tapping-mode atomic force microscopy and confocal fluorescence imaging.
Protecting the Privacy of Individuals in Terrorist Tracking Applications (2005)

Abstract : Countering terrorism involves gathering information from a wide diversity of sources to discover key facts and relationships, develop models of hypotheses, and support human reasoning on likely futures and outcomes. Many of these data sources contain sensitive personal information, such as data on telephone calls, email, credit card usage, bank accounts, car rentals, housing, educational data, health-related data, drivers' licenses, airline and hotel reservations, visas, border crossing, attendance at events, and application for government programs. In tracking potential terrorists and attempting to discover their relationships and organization, is it necessary to focus on data about individuals. Yet it is this identification of data with individuals that makes the information sensitive. The goal of this project was to allow authorized analysts to search these data for terrorist-related activity while providing a realistic degree of privacy protection for ordinary citizens who may be also represented in those databases. The proposed solution has the following elements: Inference control to prevent unauthorized individuals from completing queries that would allow identification of ordinary citizens, access control to return sensitive identifying data to appropriately authorized users, Immutable audit logs that ensure all data accesses are recorded immediately and permanently with no possibility of alteration.
Beryllium-silicon disorder and rare earth crystal chemistry in gadolinite from the White Cloud pegmatite, Colorado, USA (2020)

ABSTRACT Gadolinite, REE2FeBe2Si2O10, is a monoclinic orthosilicate member of the gadolinite supergroup of minerals and occurs in beryllium and rare earth element (REE) bearing granites, pegmatites, and some metamorphic rocks. Gadolinite from the White Cloud pegmatite, South Platte Pegmatite district, Colorado, USA, has been investigated and shows unusually variable REE compositions and distinct Be-Si disorder. Crystal structure and chemistry of two petrographically distinct gadolinite samples from this locality have been studied by electron microprobe chemical analysis, laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS), single-crystal X-ray diffraction (XRD), and micro-Raman spectroscopy. Within these samples, the gadolinite was found to range from gadolinite-(Y) to gadolinite-(Ce). Regions of nearly full occupancy of Fe at the M site, and partial substitution of Si for Be at the Q tetrahedral site, as well as substitution of Be for Si at the T site were observed, with up to 15% vacancy at the Fe site and up to 15% disorder between Be and Si at distinct tetrahedral sites elsewhere. The layered nature of the crystal structure allows for large variation of the radius of the cation at the A site which contains the REE. This study shows that Be may substitute for Si and that Be may be more abundant in geochemical systems than previously assumed.
Impact of test-fixture forward coupling on on-wafer silicon device measurements (2000)

Often, the test-fixture forward coupling is ignored during on-wafer device measurements, although existing de-embedding techniques provide means for addressing its effect. In this work it is demonstrated that large errors may occur if forward coupling is not determined and accounted for. An investigation based on basic scaling properties of MOSFETs is proposed as a benchmark test to partially verify de-embedding methods.

Single Exposure EUV of 32nm pitch logic structures: Patterning performance on BF and DF masks (2018)

This paper summarizes findings for an N5 equivalent M2 (pitch 32) layer patterned by means of SE EUV. Different mask tonalities and resist tonalities have been explored and a full patterning (litho plus etch) process into a BEOL stack has been developed. Resolution enhancement techniques like SRAFs insertion and retargeting have been evaluated and compared to a baseline clip just after OPC. Steps forward have been done to develop a full patterning process using SE EUV, being stochastics and variability the main items to address.
How Can a Hydrophobic MOF be Water‐Unstable? Insight into the Hydration Mechanism of IRMOFs (2012)

We report an ab initio molecular dynamics study of the hydration process in a model IRMOF material. At low water content (one molecule per unit cell), water physisorption is observed on the zinc cation but the free⇄bound equilibrium strongly favors the free state. This is consistent with the hydrophobic nature of the host matrix and its type-V isotherm observed in a classical Monte Carlo simulation. At higher loading, a water cluster can be formed at the Zn(4)O site and this is shown to stabilize the water-bound state. This structure rapidly transforms into a linker-displaced state, where water has fully displaced one arm of a linker and which corresponds to the loss of the material's fully ordered structure. Thus an overall hydrophobic MOF material can also become water unstable, a feature that has not been fully understood until now.
Associations between specific antibody responses and resistance to reinfection in a Senegalese population recently exposed to Schistosoma mansoni (2007)

Summary We examined associations between schistosome‐specific antibody responses and reinfection in Senegalese individuals recently exposed to Schistosoma mansoni . The effects of treatment, age, intensity of infection and duration of exposure on schistosome‐specific antibody responses were also investigated by comparing immune responses in individuals exposed for less than 3 years with responses in people exposed for more than 8 years. All individuals were bled before treatment as well as 6 and 12 weeks after. We used a statistical model that included interaction terms between time, age, infection intensity and duration of exposure. The overall patterns of most specific antibody responses by age were similar to those previously published for S. mansoni , Schistosoma japonicum and Schistosoma haematobium infections in different endemic areas. In general, a boost in specific antibody responses against adult worm antigen (SWA) was observed at 6 weeks after treatment whereas the majority of isotype responses against egg antigen (SEA) were not affected by treatment. Our analysis showed that the effect of treatment on schistosome‐specific antibody responses is influenced by age, infection intensity and duration of exposure. We found no evidence that treatment matures the specific antibody response of children recently infected with S. mansoni . Our results indicate that the build‐up of potentially protective immunoglobulin E (IgE) responses was associated with duration of exposure, or, in other words, experience of infection. Interestingly, in recently exposed individuals there was a significant association between IgA responses to SWA and resistance to reinfection. Resistance to reinfection and production of IgA‐SWA was associated with adulthood independently of exposure patterns, suggesting that susceptibility to S. mansoni and the development of protective immune responses is age‐dependent.
Authentication on Untrusted Remote Hosts with Public-key Sudo (2008)

Two common tools in Linux- and UNIX-based environments are SSH for secure communications and sudo for performing administrative tasks. These are independent programs with substantially different purposes, but they are often used in conjunction. In this paper, we describe a weakness in their interaction and present our solution, public-key sudo. Public-key sudo1 is an extension to the sudo authentication mechanism which allows for public key authentication using the SSH public key framework. We describe our implementation of a BSD SSH authentication module and the SSH modifications required to use this module.
Experimental Study on the Characteristics of Ignition during Microwave Drying of Lignite (2016)

Abstract The spontaneous combustion of lignite during microwave drying was evaluated with the focus on the effects of, for example, microwave power and output mode, the final temperature of the samples, and the oxygen content of the drying atmosphere on the moisture contents corresponding to the ignition (IMCs). This empirical study was performed using a laboratory‐scale microwave oven. The lowest IMCs and the optimal drying effect of lignite were achieved using a power level of 60 W g −1 , final surface temperature of 85–90 °C, and a lower oxygen content; pulsed microwave radiation could significantly lower the risk of ignition by reducing the overall surface temperature. In addition, the ignition temperatures at different moisture contents were measured comparatively by using conventional and microwave heating methods. Fourier transform infrared analyses of the samples revealed that microwave drying can upgrade the coal rank without affecting the coal quality.
CARD28: Prolonged Graft Preservation of Biostasis Induced Porcine Hearts using the VP.S ENCORE® Machine Perfusion Device (2023)

Purpose: Heart transplantation is the gold standard therapy for patients with end-stage heart failure. However, the supply of donor hearts does not meet the demand, and many patients die on the waitlist. The purpose of this study was to test the efficacy of a novel machine perfusion device, the VP.S ENCORE® cardiac preservation device, in preserving porcine hearts conditioned with a biostasis-inducing compound (WC1) during prolonged 6-8 hour perfusion. Methods: Isolated porcine hearts were recovered under anesthesia. Following cannulation, the hearts were placed in the VP.S ENCORE® cardiac preservation device for oxygenated perfusion at 23-25°C for either 6 (n = 3) or 8 (n = 4) hours. At hour 3, WC1 (n = 2) was administered through the arterial line and the hearts continued to be perfused for additional 5 hours. Hourly flow, pressure, temperature, blood gases, and various metabolites were recorded. After preservation, hearts were placed in a Langendorff model for reperfusion and evaluated for cardiac function. Biopsy samples were taken before and at the end of preservation for histological and gene expression analyses. Results: During perfusion, oxygen consumption was significantly reduced in WC1-treated hearts (p < 0.0001). However, during re-perfusion, WC1-treated hearts had an initial lower oxygen consumption that recovered to normal with time and temperature. Before defibrillating the hearts, oxygen consumption was 1.61 ± 0.59 (vehicle) & 1.05 ± 0.39 (WC1), while after defibrillation the oxygen consumption increased to 3.29 ± 0.63 & 2.66 ± 0.32 ml/min/100g, respectively. The contractility of the WC1-treated hearts was similar to a normal human heart in vivo. Furthermore, gene expression analysis showed a significant reduction (p < 0.0008) of inflammation (IL-6, TNFα), hypoxia (Hif1a), & cell death markers (p53) in WC1 treated hearts when compared to control hearts. Conclusions: Our preliminary results demonstrate that the portable, simple-to-use VP.S ENCORE® cardiac preservation machine perfusion device coupled with the torpor properties of compounds like WC1 may provide a new paradigm to prolonged organ preservation, and may offer many advantages over currently tested machine perfusion technologies. Further, this innovative work is a result of integrating science and engineering to target unmet patients’ needs in the field of organ preservation.Figure 1.

[Methodology of myocardial scintigraphy with thallium 201: limits of pathological findings]. (1977)

Thallium 201 is a useful agent for demonstrating ischemic myocardia. It is injected during maximum stress, the stress situation is then continued for a further 2 min and a series of scans are carried out 5-25 min after injection. The series is repeated 3-5 h after injection, thereby obtaining pictures of myocardial resting and stress perfusion. Repitition of the study without stress reveals no further data. In follow-up examinations under the same stress situation the perfusion defects remain the same. 27 normal subjects were evaluated and the limits between normal and pathologic scans established.
A memory polynomial based adaptive digital pre-distorter for optical communication transmitters (2017)

We present a robust adaptive digital pre-distortion technique to mitigate the linear and non-linear degradation of optical communication transmitter components. The proposed method is based on the principles of memory polynomial based pre-distortion and indirect learning architecture. Effectiveness of the presented algorithm is assessed across various higher order modulation formats and higher baud rates. Significant gains are reported in back-to-back measurements and various lab and field trial experiments.

Integrated analyses of growth differentiation factor-15 concentration and cardiometabolic diseases in humans (2022)

Growth differentiation factor-15 (GDF15) is a stress response cytokine that is elevated in several cardiometabolic diseases and has attracted interest as a potential therapeutic target. To further explore the association of GDF15 with human disease, we conducted a broad study into the phenotypic and genetic correlates of GDF15 concentration in up to 14,099 individuals. Assessment of 772 traits across 6610 participants in FINRISK identified associations of GDF15 concentration with a range of phenotypes including all-cause mortality, cardiometabolic disease, respiratory diseases and psychiatric disorders, as well as inflammatory markers. A meta-analysis of genome-wide association studies (GWAS) of GDF15 concentration across three different assay platforms (n=14,099) confirmed significant heterogeneity due to a common missense variant (rs1058587; p.H202D) in <i>GDF15</i>, potentially due to epitope-binding artefacts. After conditioning on rs1058587, statistical fine mapping identified four independent putative causal signals at the locus. Mendelian randomisation (MR) analysis found evidence of a causal relationship between GDF15 concentration and high-density lipoprotein (HDL) but not body mass index (BMI). Using reverse MR, we identified a potential causal association of BMI on GDF15 (IVW p<sub>FDR</sub> = 0.0040). Taken together, our data derived from human population cohorts do not support a role for moderately elevated GDF15 concentrations as a causal factor in human cardiometabolic disease but support its role as a biomarker of metabolic stress.

Intraobserver Repeatability of Automated versus Adjusted Optical Coherence Tomography Measurements in Patients with Neovascular Age-Related Macular Degeneration (2007)

The repeatability of adjusted retinal thickness measurements, in which the errors of retinal boundary detection by OCT analysis software is corrected by the operator using scan profiling, is found to be higher than that of automated ones in this small group of NVAMD patients when performed by a single experienced operator.
Compact model for photo-generation current in organic solar cell (2011)

A compact model is presented for the photo-generation current in organic solar cell. It is developed rigorously by extending the photo-generation current in Goodman [A. M. Goodman and A. Rose, J. Appl. Phys. 7, 2823 (1971)] to include charge variable range hopping transport and recombination in organic semiconductors. Based on the extended model, a variety of temperature/material disorders and light intensity dependence of the photo-generation current can be well described. Good agreement between the calculation and recent experimental data is also observed.

Minimization of Iron Losses of Permanent Magnet Synchronous Machines (2005)

In permanent magnet (PM) synchronous machines, iron losses form a larger portion of the total losses than in induction machines. This is partly due to the elimination of significant rotor loss in PM machines and partly due to the nonsinusoidal flux density waveforms in the stator core of PM machines. Therefore, minimization of iron losses is of particular importance in PM motor design. This paper considers the minimizing of iron losses of PM synchronous machines through the proper design of magnets and slots, and through the choice of the number of poles. Both time-stepped finite element method (FEM) and the iron loss model from a previous study are used in this paper to draw the conclusions.

Methanogenic archaea use a bacteria-like methyltransferase system to demethoxylate aromatic compounds (2021)

Methane-generating archaea drive the final step in anaerobic organic compound mineralization and dictate the carbon flow of Earth's diverse anoxic ecosystems in the absence of inorganic electron acceptors. Although such Archaea were presumed to be restricted to life on simple compounds like hydrogen (H<sub>2</sub>), acetate or methanol, an archaeon, Methermicoccus shengliensis, was recently found to convert methoxylated aromatic compounds to methane. Methoxylated aromatic compounds are important components of lignin and coal, and are present in most subsurface sediments. Despite the novelty of such a methoxydotrophic archaeon its metabolism has not yet been explored. In this study, transcriptomics and proteomics reveal that under methoxydotrophic growth M. shengliensis expresses an O-demethylation/methyltransferase system related to the one used by acetogenic bacteria. Enzymatic assays provide evidence for a two step-mechanisms in which the methyl-group from the methoxy compound is (1) transferred on cobalamin and (2) further transferred on the C<sub>1</sub>-carrier tetrahydromethanopterin, a mechanism distinct from conventional methanogenic methyl-transfer systems which use coenzyme M as final acceptor. We further hypothesize that this likely leads to an atypical use of the methanogenesis pathway that derives cellular energy from methyl transfer (Mtr) rather than electron transfer (F<sub>420</sub>H<sub>2</sub> re-oxidation) as found for methylotrophic methanogenesis.
Enormously high-peak-power optical pulse generation from a single-transverse-mode GaInN blue-violet laser diode (2010)

We have demonstrated extraordinary optical pulse generation with a peak-power of 55 W and pulse duration of 15 ps by intense electrical pulse excitation of a 401 nm GaInN laser diode (LD). Electrical pulse excitation of a GaInN LD which contained a thicker electron blocking layer gave rise to abnormal behavior with a several nanosecond-long delay and apparent Q-switching under intense excitation. Operation of this LD under such excitation was found to produce highly intense optical pulses even in semiconductor lasers with a single-transverse-mode.
