Thermoelectric Gas Sensor using Au Loaded Titania CO Oxidation Catalyst (2007)

Au loaded TiO2 (Au/TiO2) ceramic thick film catalyst was integrated on a micro Thermoelectric Gas Sensor (TGS). We have investigated the catalytic activity of the Au/TiO2 catalyst for CO oxidation and the CO sensing performance of the micro-TGS with this catalyst. CO started to burn when the Au/TiO2 catalyst was exposed to 1 vol% CO in air at an operating temperature of 150°C, which was detected by the output voltage of the TGS. A good linearity between the CO concentrations in air (from 250 ppm to 1 vol%) and the voltage signal of the sensor (from 0.15 mV to 5.0 mV) was obtained at an operating temperature of 200°C.
Dynamic Kinetic Asymmetric Transformation (DYKAT) by Combined Amine‐ and Transition‐Metal‐Catalyzed Enantioselective Cycloisomerization (2009)

The first examples of one-pot highly chemo- and enantioselective dynamic kinetic asymmetric transformations (DYKATs) involving alpha,beta-unsaturated aldehydes and propargylated carbon acids are presented. These DYKATs, which proceed by a combination of catalytic iminium activation, enamine activation, and Pd(0)-catalyzed enyne cycloisomerization, give access to functionalized cyclopentenes with up to 99 % ee and can be used for the generation of all-carbon quaternary stereocenters.
Time-Varying Channel Estimation in OFDM Systems with Null Subcarriers (2008)

In this paper, we propose a robust channel estimation method in OFDM systems over fast fading channels. In consideration of the effect of null subcarriers, the proposed channel estimation is first performed in the frequency domain. By making efficient use of channel correlation and the property of ICI to reduce the number of needed parameters for channel estimation, robust channel estimation for ICI is accomplished in parallel, pilot cluster by pilot cluster. It is then transformed into the time domain to obtain a gain in noise reduction and to reduce interpolation error as well. Simulation results show that the proposed channel estimation has good performance compared to previous works.
RadioResUNet: Wireless Measurement by Deep Learning for Indoor Environments (2022)

This paper introduces a wireless measurement method by deep learning that trains raytracing data and inferences wireless conditions in indoor environments. For indoor wireless measurement by deep learning, we prepare a large-scaled training dataset consisting of indoor interior models imitating various real indoor environments and radiomap images generated by raytracing radio wave propagation in the indoor interior models. In addition, we propose a deep learning model for inferencing the indoor wireless conditions, namely RadioResUNet, that is based on a convolutional neural network (CNN). To evaluate the deep learning model, we compare the proposed deep learning model of RadioResUnet with the existing deep learning model of RadioUNet. To verify the feasibility and effectiveness of the proposed RadioResUNet, in addition, we compare the received signal strength results by deep learning measurement with those by actual measurement in the indoor environment and show the effectiveness and challenges of the deep learning model of indoor wireless measurement.
Energy-secure swarm power management (2018)

This paper presents a visionary proposal for a distributed (or decentralized) power/thermal control mechanism that applies the bio-inspired artificial intelligence paradigm of swarm intelligence. The target use case is a future many-core processor. Preliminary results based on a swarm simulator are presented. The paper then addresses the challenge of making such power control systems secure against energy attacks - i.e. maliciously launched virus programs that are designed to disrupt the power control mechanism and cause performance shortfalls or even physical damage from over-heating.
The Work of Designers: Cultures of Making and Representation (2011)

Abstract This chapter deals with a particular kind of contemporary human work: the professional work done by designers. It examines the work of design from the perspective of research with designers from across the spectrum of modern work. It addresses the attention investment. The patterns of work in the work of design are creativity, models and representations, collaboration over periods of time, and managerial processes, social networks, society, markets and regulation, and the work of professional communities. This chapter shows the ways in which the guiding processes of building artificial environments and products for humans have been developed through design work.
Differential Polarization Shift Keying Through Reconfigurable Intelligent Surfaces (2022)

We propose a novel reconfigurable intelligent surface (RIS) encoded information transmission scheme for a line-of-sight environment. A RIS fed with data modulates the information on impinging waves emitted from an external source in the states of polarization (SoP) of the scattered waves by performing a novel differential polarization shift keying. In particular, the information is encoded in the change of the SoP over two successive scattering slots. The proposed scheme is immune to the SoP fluctuations in the wireless channel which allows for non-coherent detection at the receiver.
Functional Description of Event Notification Filtering (2006)

The SIP event notification framework describes the usage of the Session Initiation Protocol (SIP) for subscriptions and notifications of changes to the state of a resource.The document does not describe a mechanism whereby filtering of event notification information can be achieved.This document describes the operations a subscriber performs in order to put filtering rules associated with a subscription to event notification information in place.The handling, by the subscriber, of responses to subscriptions carrying filtering rules and the handling of notifications with filtering rules applied to them are also described.Furthermore, the document conveys how the notifier behaves when receiving such filtering rules and how a notification is constructed.
Enhanced itaconic acid production in Aspergillus niger using genetic modification and medium optimization (2012)

The performance of gpdA and hbd1 transformants was found not to be beneficial for itaconic acid production using the tested cultivation conditions. Medium optimization showed that, copper was positively correlated with improved itaconic acid production. Interestingly, the optimal conditions for itaconic acid clearly differ from conditions optimal for citric- and oxalic acid production.
The high temperature behavior of trace hydrous components in silicate minerals (1985)

We have studied the high temperature behavior of water and hydroxide in quartz, feldspar, topaz, zircon, muscovite, cordierite, and beryl using high temperature infrared spectroscopy. We have directly observed processes such as dehydration and changes in hydrogen speciation. In some minerals trace hydroxyl and water speciation and properties at temperatures of geologic interest can be dramatically different from those at 25°C. In muscovite, no changes in
speciation occur prior to dehydration at 750°C, whereas in topaz hydroxyl sites interconvert at 500 °C. In metamict zircon strongly hydrogen-bonded hydroxyl is preferentially lost from a continuum of sites during continuous dehydration occurring from 400° to 900°C. There are
only minor changes in the O-H region spectrum of natural quartz at the ɑ-β transition point. In feldspar one type of molecular water is lost at ~200°C, and at 600° to 800° a second water type converts irreversibly to a new hydrous species. Changes at high temperature common to the infrared absorption bands of all minerals studied are: broadening, a shift to lower wave numbers, and a slight decrease in integral intensity. Temperature coefficients for 0-H stretching peak shifts range from 0 to -0.045 cm^(-1)/°C. Lattice modes also broaden and shift to lower wave numbers, typically with temperature coefficients of about -0.03 cm-^(-1)/°C.
Real-time processing in dynamic ultrasound elastography: A GPU-based implementation using CUDA (2012)

This paper addresses the computational cost of the normalized cross-correlation (NCC) algorithm in ultrasound elastography. Parallel implementations of the NCC algorithm based on multicore architectures and a graphical processor unit (GPU) are formulated and applied to radio-frequency (RF) data from dynamic elastography experiments. Compared to single computer processor unit (CPU) performances, results show that parallel implementation of the NCC algorithm allows speedups of less than 5 for multi-threaded execution on CPU and up to 85 using a GPU. Processing frame rates from 80 to 173 sec <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> have been achieved for large fields of view with good spatial resolution. The trade-off between accuracy, spatial resolution and computational cost in displacement estimation using the NCC algorithm therefore appears obsolete. Open source codes for implementing the NCC algorithm on GPU are made available at www.lbum-crchum.com.
Spatial simulation of the instability of channel flow with local suction/blowing (1997)

A direct numerical simulation was made of instability in a spatially evolving channel flow. A local surface suction/blowing was imposed at the upper wall (x/h=20). A Tollmien–Schlichting (TS) wave was superimposed on the laminar channel flow at the inflow. At the outflow, the buffer domain technique was applied to suppress the reflection of outgoing waves. The influence of the local suction/blowing on the linear and nonlinear instabilities of the flow was examined. It was found that the local suction/blowing increases the disturbance energy significantly in the interaction zone for subcritical (Re=5000) and supercritical (Re=10 000) cases. The effects of the blowing strength (0⩽AS⩽0.1) and the initial TS wave amplitude (0⩽ATS⩽2.0) on the subcritical channel flow were scrutinized. Two regimes of the wave/flow interaction were found by varing AS, i.e., “monotonic” and “vortex splitting” regimes.
Metal-vapor deposition modulation on polymer surfaces prepared by the coffee-ring effect (2013)

We report a novel function of a polymer coffee-ring surface called metal-vapor deposition modulation where metal-vapor atoms are deposited on the center of the polymer coffee-ring surface using vacuum evaporation but not on the ring-shaped areas at the edge. The essential factor of the metal-deposition modulation is the difference of polymer chain mobility between the center and the ring. In the ring, the solvent evaporation process produces large spaces among surface polymer chains, resulting in high mobility of polymer chains. The desorption of metal vapor atoms from the surface was caused by the high mobility of the polymer chains. This result not only provides new knowledge about the fundamentals of a polymer surface but also suggests a novel technology for engineering and industrial fields using metallic coating technology on polymer surfaces.
The N-Terminus of Hepcidin Is Essential for Its Interaction with Ferroportin: Structure-Function Study. (2005)

Abstract Hepcidin, a small peptide produced by the liver, is the principal iron-regulatory hormone. It acts by binding to the iron exporter ferroportin, inducing its internalization and degradation, thereby blocking cellular iron efflux. The bioactive 25 amino acid peptide has a hairpin structure stabilized by 4 disulfide bonds. We synthesized a series of hepcidin derivatives and determined their bioactivity in a cell line expressing ferroportin-GFP fusion protein, by measuring the degradation of ferroportin-GFP and the accumulation of ferritin after peptide treatment. Bioactivity was also assayed in vivo, by measuring hypoferremia in mice injected with hepcidin derivatives. Serial deletion of N-terminal amino acids caused progressive decrease in activity which was completely lost when five N-terminal aa were deleted. Synthetic 3-aa and 6-aa N-terminal peptides alone, however, did not internalize ferroportin, and did not interfere with ferroportin internalization by native hepcidin. Deletion of two C-terminal amino acids did not affect peptide activity. Removal of individual disulfide bonds by pairwise substitution of cysteines with alanines also did not impact peptide activity in vitro. However, these peptides were significantly less active in vivo, likely due to their decreased stability in circulation. Peptides with a substitution G71D or K83R, previously described in human subjects, were fully active in vitro and in vivo. Zebrafish hepcidin, which is only 60% similar to human hepcidin, but with conservative substitutions at the N-terminus, was as active as its human counterpart. Apart from the essential nature of the N-terminus, hepcidin structure appears permissive for mutations. Further studies of hepcidin structure in relation to its function are essential for the design of hepcidin antagonists and agonists which could be used for treatment of iron disorders.
Testicular function in cultured postnatal mouse testis fragments is similar to that of animals during the first wave of spermatogenesis (2019)

These findings show this in vitro mouse testis organ culture model may be a useful and convenient tool for mechanistic studies. However, because germ cell differentiation in all seminiferous tubules was not observed, improvements in the system/methods are needed to more closely replicate spermatogenesis as observed in animals.
A Testbed for Scheduling with Alternative Process Plans (1997)

ABSTRACTThis article is concerned with the problem of real-time reactive scheduling using alternative process plans. The usefulness of alternative process plans for relieving bottlenecks and increasing throughput has been well established in the literature. Despite the advantages of using alternative plans, the complexity of this problem has prevented it from being studied extensively. Therefore, this paper has three aims. The first aim is to review the groundwork that has been laid to date. The second aim is to identify the key research issues that need to be addressed before the goal of real-time reactive scheduling with alternative process plans can be realized. The third aim of the paper is to describe a testbed currently under development for testing and benchmarking scheduling algorithms which use alternative process plans.

Identification of nine new HLA class I alleles in volunteers from the Singapore stem cell donor registries (2006)

Based on unusual probe hybridization patterns, two human leukocyte antigen (HLA)-A, five HLA-B, and two HLA-C alleles (A*240208, A*3211Q; B*1822, B*3938Q, B*4606, B*4607N, B*5139; Cw*0321, Cw*0734) were identified in individuals from the Singapore Bone Marrow Donor Program and Singapore Cord Blood Bank. Eight of the nine alleles encode amino acid substitutions altering the antigen-binding region including three alleles with changes altering a cysteine at codon 164 (A*3211Q, B*3938Q, B*4607N). This substitution either eliminates a key disulfide bond or results in a stop codon, both likely affecting the expression of the HLA molecules. Only one allele (A*240208) carries a synonymous substitution.
Data Mining For Web Security: UserWatcher * (2001)

Data mining techniques have proved to be efficient for discovering interesting and useful patterns in large amount of data such as in Web documents. This paper investigates the use of mining techniques to secure Web access. We propose UserWatcher, a mining tool that integrates Web usage mining and Web content mining to find potential correlations between data that a user accesses and the data that he/she produces. Applied to security, UserWatcher can be used to detect information misusage by authorized users and to detect anomalies in current system policies.

Design and Implementation of an Adaptive Smart Antenna System (2006)

This paper presents practical design of a smart antenna system based on direction-of-arrival estimation and adaptive beamforming. Direction-of-arrival estimation is based on the MUSIC algorithm for identifying the directions of the source signals incident on the sensor array comprising the smart antenna system. Adaptive beamforming is achieved using the LMS algorithm for directing the main beam towards the desired source signals and generating deep nulls in the directions of interfering signals. The smart antenna system designed involves a hardware part which provides real data measurements of the incident signals received by the sensor array. Results obtained verify the improved performance of the smart antenna system when the practical measurements of the signal environment surrounding the sensor array are used. This takes the form of sharper peaks in the MUSIC angular spectrum and deep nulls in the LMS array beampattern

Probing partial/biased agonism at the G protein‐coupled A 2B adenosine receptor (662.11) (2014)

The A 2B adenosine receptor (AR) is involved in many important functions and couples to several G proteins, but the endogenous effects have not been well documented partly due to the lack of selective agonists at this subtype until recently. In the present study, we probed the potential partial and/or biased agonism at the A 2B AR in several types of cells, including HEK293 cells and T24 bladder cancer cells, using a series of A 2B agonists of adenosine analogs substituted at 5’, N 6 and C2 positions, including NECA, MRS5911 and MRS3997, and the non‐nucleoside A 2B agonist, BAY60‐6583. All A 2B agonists tested induced accumulation of cyclic AMP fully or partially in all cells tested, with NECA being the most efficacious. However, only 5’‐substituted analogs are full agonists in calcium mobilization and ERK1/2 phosphorylation. Over‐expression of the A 2B AR in HEK293 cells increased the agonist potency and efficacy in inducing the Gs‐mediated accumulation of cyclic AMP, but not the ability to induce calcium mobilization by the C2‐substituted adenosine derivatives or non‐adenosine A 2B agonists. Results from an arrestin translocation assay showed that the 5’‐substituted NECA is more efficacious than adenosine derivatives substituted at C2 and N6 positions and non‐adenosine agonists. BAY actually did not induce arrestin translocation in this assay. The data suggest that 5’‐substituted adenosine analogs are balanced agonists of different pathways, whereas the C2‐ and N 6 ‐substituted adenosine analogs and the class of non‐nucleoside A 2B agonists are Gs‐biased agonists. The data also suggest that BAY and some N 6 ‐ and C2‐substituted adenosine analogs may be full agonist, partial agonist or antagonist under various conditions. Indeed, BAY behaves as an A 2B antagonist to induce insulin release in MIN6 pancreatic β cells. Thus, differences in efficacy and effector pathways might explain some of the contradictory results reported for A 2B AR activation. Grant Funding Source : Supported by NIDDK Intramural Research, NIH

Early management of presbycusis: recommendations from the French Society of Otorhinolaryngology and Head and Neck Surgery, the French Society of Audiology, and the French Society of Geriatrics and Gerontology (2023)

In case of a clinical profile suggestive of presbycusis in a young subject, especially if there are several family cases, it is recommended to propose a genetic investigation. It is recommended to perform free-field speech audiometry in noise to measure intelligibility in an environment as close as possible to reality. Questionnaires can be used in addition to audiometry to best assess the patient's disability. It is recommended that hearing rehabilitation with a hearing aid or cochlear implant may slow or prevent cognitive decline. Combined auditory and cognitive rehabilitation should be offered regardless of the time elapsed since the fitting. It is recommended to integrate programs accessible via smartphones, tablets or the Internet, integrating different training domains in addition to face-to-face sessions.
