Analysis of Photoluminescence and Dosimetric Properties of (Ce, Tb)-codoped Magnesium Orthosilicate Single Crystals (2023)

In this study, Mg 1.995-x SiO 4 :xCe, 0.005Tb (x = 0 and 0.01) single crystals were synthesized by the floating zone method and their photoluminescence (PL) and dosimetric properties were evaluated.In the PL process, emission peaks due to the 4f-4f transitions of Tb 3+ ions were observed in the x = 0 and 0.01 samples, and the emission peak due to the 5d-4f transitions of Ce 3+ ions was detected in the x = 0.01 sample.In the thermally stimulated luminescence (TSL) process, only emission peaks due to the 4f-4f transitions of Tb 3+ ions were observed in both samples, and the x = 0.01 sample had higher TSL intensity than the x = 0 sample.The x = 0.01 sample showed a lower detection limit of 0.01 mGy and a spatial resolution of 50.0 μm under X-ray irradiation.
Exploring doping options and variability of trigate transistors using atomistic process and device simulations (2010)

This work explores several options for the channel-stop implant and source/drain doping for bulk trigate transistors using three-dimensional atomistic simulation. Considering tight silicon fin spacing and difficulty of using conventional ion implantation for the source/drain doping, the authors model both the implantation and plasma doping options. Considering the size of silicon fin and a handful of dopant atoms at play, the kinetic Monte Carlo approach offers a natural way of investigating atomistic effects and device variability. Atomistic device simulation provides an insight into the impact of different doping options on performance and variability of the trigate transistors. The provided insight is instrumental in selecting the best doping options and optimizing the tradeoff between performance and variability.
Selective Removal of Nitrogen from Quinoline and Petroleum by Pseudomonas ayucida IGTN9m (2000)

Enrichment culture experiments employing soil and water samples obtained from petroleum-contaminated environments succeeded in the isolation of a pure culture possessing the ability to utilize quinoline as a sole nitrogen source but did not utilize quinoline as a carbon source. This culture was identified as Pseudomonas ayucida based on a partial 16S rRNA gene sequence, and the strain was given the designation IGTN9m. Examination of metabolites using thin-layer chromatography and gas chromatography-mass spectrometry suggests that P. ayucida IGTN9m converts quinoline to 2-quinolinone and subsequently to 8-hydroxycoumarin. Resting cells of P. ayucida IGTN9m were shown to be capable of selectively removing about 68% of quinoline from shale oil in a 16-h treatment time. These results suggest that P. ayucida IGTN9m may be useful in petroleum biorefining for the selective removal of organically bound nitrogen from petroleum.
Phase selector for RFID localization system based on RSSI filter (2019)

The Radio Frequency Identification (RFID) localizations systems are actually from the most used in indoor environment. But this kind of closed environment allays presents more perturbation due to walls, roofs, obstacle presence and generally affect the measurements especially sensible parameters like the signal phase which can provide precious additional information for a better accuracy. In this work, we propose an alternative to resolve this problem; we propose a phase cleansing algorithms based on Received Signal Strength Indicator (RSSI) selection. Our proposition consists to select just the phases corresponding to the best reads based on RSSI. Then, we use the selected phases as a metric for localization without using RSSI. We test our proposed approach on an RFID localization system composed from a set of EPC global Class-1 Gen-2 UHF RFID tags, an UHF RFID reader using a 7dbi antenna and a computer for data acquisition and processing. The system is carried by an operator and measurement zone was placed on a wall of $5.5 m \times 1.25 m$.
Spectral anomaly detection using graph-based filtering for wireless sensor networks (2014)

This paper introduces a novel spectral anomaly detection method by developing a graph-based filtering framework. In particular, we consider the problem of unsupervised data anomaly detection over wireless sensor networks (WSNs) where sensor measurements are represented as signals on a graph. In our framework, graphs are chosen to capture useful proximity information about measured data. The associated graph-based filters are then employed to project the graph signals on normal and anomaly subspaces, and resulting projections are used in detection of data anomalies. The proposed approach has two main advantages over the standard spectral technique, principal component analysis (PCA). Firstly, graph-based filtering allows us to incorporate structural information known a priori (e.g., distance between sensors) in addition to data. Secondly, it provides localized transformations leading to effective distributed anomaly detection. Our experimental results show that our proposed solution outperforms PCA-based and distributed clustering-based anomaly detection methods in terms of receiver operating characteristics (ROCs).
Information interoperability and provenance for emergency preparedness and response (2009)

Improved situation awareness is a key enabler of better emergency preparedness and response (EP&R). This paper describes two important challenges: information interoperability and provenance. The former enables meaningful information exchange across separately developed systems, while the latter gives users context that helps them interpret shared information and make trust decisions. We present applied research in information interoperability and provenance, describe our collaborations with leading industrial and academic partners, and illustrate how the resulting tools improve information sharing during preparation, training/exercises, ongoing operations, and response.
Fully automatic detection of corresponding anatomical landmarks in volume scans of different respiratory state (2006)

A method is described which provides fully automatic detection of corresponding anatomical landmarks in volume scans taken at different respiratory states. The resulting control points are needed for creating a volumetric deformation model for motion compensation in radiotherapy. Prior to treatment two CT volumes are taken, one scan during inhalation, one during exhalation. These scans and the detected control point pairs are taken as input for creating the four-dimensional model by using thin-plate splines.

ITdU preferentially targets DNA in proliferating tumor cells and leads to apoptosis provided that the thymidylate synthase is inhibited.
Longitudinal profiling of human blood transcriptome in healthy and lupus pregnancy (2019)

Systemic lupus erythematosus carries an increased risk of pregnancy complications, including preeclampsia and fetal adverse outcomes. To identify the underlying molecular mechanisms, we longitudinally profiled the blood transcriptome of 92 lupus patients and 43 healthy women during pregnancy and postpartum and performed multicolor flow cytometry in a subset of them. We also profiled 25 healthy women undergoing assisted reproductive technology to monitor transcriptional changes around embryo implantation. Sustained down-regulation of multiple immune signatures, including interferon and plasma cells, was observed during healthy pregnancy. These changes appeared early after embryo implantation and were mirrored in uncomplicated lupus pregnancies. Patients with preeclampsia displayed early up-regulation of neutrophil signatures that correlated with expansion of immature neutrophils. Lupus pregnancies with fetal complications carried the highest interferon and plasma cell signatures as well as activated CD4<sup>+</sup> T cell counts. Thus, blood immunomonitoring reveals that both healthy and uncomplicated lupus pregnancies exhibit early and sustained transcriptional modulation of lupus-related signatures, and a lack thereof associates with adverse outcomes.

The 1.1 mm Bolocam Lockman Hole Galaxy Survey: Submillimeter Confirmations and Fluctuation Analysis (2005)

Submillimeter galaxies are high redshift (z&gt;1), high luminosity (~1013 Lsolar) galaxies with large inferred star formation rates (~103 Msolar per year). Such extreme star formation rates make it important to characterize this population of galaxies to understand massive galaxy formation. &#13;\n&#13;\nWe surveyed 324 square arcminutes of sky for submillimeter galaxies at 1.1 mm toward the Lockman Hole, using Bolocam on the Caltech Submillimeter Observatory. We previously reported the detection of seventeen galaxy candidates (with seven expected false detections). Here we report: 1) the detection of nine of the galaxy candidates at 350 microns with SHARC-2 and 2) the results of a fluctuation analysis (P(D), where P is the probability of a signal deflection D). The nine 350 micron detections confirm the robustness of the 1.1 mm detections. Together with far-infrared, submillimeter, millimeter, and VLA data, where available, these observations sample the spectral energy distributions for estimates of luminosities and star formation rates. &#13;\n&#13;\nThe P(D) analysis was enabled by the extremely uniform noise in the map, resulting from the build-up of the map with repetitive scans of the same patch of sky with even sampling. In a P(D) analysis, the histogram of map pixel values is compared to a histogram comprised of random realizations of noise summed with galaxies drawn from a model distribution. A broad range of power law models were tested. The best fit power law (N=N0S-a) has a well-constrained spectral index of a=2.7. The uncertainty in the normalization N0 is dominated by systematic calibration uncertainties. This is in broad agreement with previous observations and theoretical predictions, but with much tighter error bars. &#13;\n&#13;\nThis work was supported, in part, by a grant from the National Science Foundation.
Is This The Right Place? Geometric-Semantic Pose Verification for Indoor Visual Localization (2019)

Visual localization in large and complex indoor scenes, dominated by weakly textured rooms and repeating geometric patterns, is a challenging problem with high practical relevance for applications such as Augmented Reality and robotics. To handle the ambiguities arising in this scenario, a common strategy is, first, to generate multiple estimates for the camera pose from which a given query image was taken. The pose with the largest geometric consistency with the query image, e.g., in the form of an inlier count, is then selected in a second stage. While a significant amount of research has concentrated on the first stage, there is considerably less work on the second stage. In this paper, we thus focus on pose verification. We show that combining different modalities, namely appearance, geometry, and semantics, considerably boosts pose verification and consequently pose accuracy. We develop multiple hand-crafted as well as a trainable approach to join into the geometric-semantic verification and show significant improvements over state-of-the-art on a very challenging indoor dataset.

A Framework of Topological Interference Management and Clustering for D2D Networks (2019)

In this paper, we develop a joint clustering and topological interference management (TIM) framework for a device-to-device (D2D) network. This scheme divides the whole network into multiple groups, each served on a different frequency, and the interference within each group is managed by TIM, based only on the connectivity pattern and not on the instantaneous channel state information (CSI). To this end, we model TIM as a low-rank-matrix-completion problem (LRMC) problem and solve it using a novel and low-complex scheme based on semidefinite programming (SDP). As for the clustering part, we develop a clustering algorithm that is suited for the LRMC approach to solve TIM while building on the SDP relaxation of the maximum- <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula> -cut algorithm, and extending it to account for each cluster’s capacity. This clustering problem turns out to be a capacitated maximum- <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula> -cut problem, for which we derive a relatively tight upper bound, that helps in determining the performance guarantee of many clustering algorithms. Simulation results show that the joint clustering-TIM can help, in some cases, improve the system degrees-of-freedom (DoF), especially in large D2D networks. Our proposed scheme also reduces the computation time of the LRMC-based TIM approach.
Clinical trials of a novel centrifugation method: axial separation (1996)

Specimen centrifugation is one of the most time-consuming tasks associated with preanalytical specimen processing. We report the first clinical use and impact study of the novel centrifugation method, axial separation, using the Axial Separation Module (ASM). The ASM centrifuges medical specimens one at a time (in 1 min 9 s) in proprietary Axial Process Containers (APC). Here we report tests of the ASM in an outpatient clinical laboratory. Use of the ASM in the outpatient clinic laboratory led to an average total improvement (decrease in total bench time) of 8 min 9 s per specimen compared with conventional centrifugation. Laboratory analysis revealed no statistical difference between plasma obtained from the APC vs that from a Becton Dickinson Vacutainer Tube. We conclude the ASM offers a cost-effective alternative to conventional centrifugation. Further, the use of axial separation may allow specimen separation to become an integral part of the phlebotomy process.
SrTiO 3 Capacitor with Relative Dielectric Constant of 200 on GaAs Substrate at Microwave Frequency (1996)

An RF-sputtered SrTiO 3 (STO) capacitor was fabricated on a GaAs substrate. Microwave characterization exhibited a relative dielectric constant ( ε r ) of 200 up to 20 GHz. This high ε r was obtained when the base electrode and the STO film were sputter-deposited in succession. A novel Pt/Ti/Pt/Ti base metal exhibited high tolerance against ion-milling, resulting in lower Ohmic resistance compared to the conventional base metal, Pt/Ti.
Negishi Coupling of Secondary Alkylzinc Halides with Aryl Bromides and Chlorides (2009)

An efficient palladium-catalyzed process has been developed for Negishi coupling of secondary alkylzinc halides with a wide range of aryl bromides and activated aryl chlorides. A palladium catalyst composed of a new biaryldialkylphosphine ligand, CPhos, effectively promotes the rate of the reductive elimination step relative to the rate of the undesired beta-hydride elimination. The broad substrate scope and excellent ratio of the desired secondary to the undesired primary coupling product make this method a powerful and reliable tool for C(sp(3))-C(sp(2)) bond formation.
ROBUST MOSAICING USING ZERNIKE MOMENTS (1999)

This paper presents an approach to the registration of individual images to one another to produce a larger composite mosaic. The approach is based on the use of the moments of Zernike orthogonal polynomials to compute the relative scale, rotation and translation between the images. A preliminary stage involves the use of an attention-like operation to estimate potential approximate correspondence points between the images based on extrema of local edge element density. Experimental results illustrate that the technique is effective in a range of environments and over a broad range of image registration parameters. In particular, our method makes few assumptions regarding the image content and yet, unlike several alternative approaches, can perform registration for images with only a limited amount of overlap.
In situ detection of Ha-ras and c-myc mRNA in cancer cell lines and tissue sections of colorectal cancer using sulfonated DNA probes. (1988)

We have previously reported the technique of in situ hybridization utilizing sulfonated DNA probes for the detection of amylase mRNA in formalin-fixed paraffin sections of human pancreas and submaxillary gland (22). Using this technique, we detected the mRNAs of Ha-ras and c-myc oncogenes in colonic cancer tissues from 24 patients, as well as in cultured cell lines. HL 60 cells, which are known to have amplified c-myc gene and accelerated transcription rate of this gene (11), and transformed NIH/3T3 cells with T24 Ha-ras were hybridized in situ with the sulfonated DNA probes of v-myc and v-Ha-ras respectively. Specific hybridization of v-myc probe for HL 60 and of v-Ha-ras probe for NIH/3T3 cells were clearly demonstrated at the cytoplasm by immunohistochemistry using a monoclonal antibody raised against sulfonated DNA. Of the colonic cancer tissues, which were freshly prepared and processed in paraffin, 6 were positive for Ha-ras mRNA and 7 were positive for c-myc mRNA. Northern blot analysis of the positive cases confirmed the validity of the results of in situ hybridization.
Novel 4 GHz Interleaved SRAM Cells With Asymmetrical Precharge in 45 nm PDSOI Technology (2014)

Novel 9T/8T SRAM cell designs are demonstrated using a fully functional 75-kb L1-cache compatible interleaved hardware based design in 45 nm SOI. An integrated read stack, together with an asymmetrical precharge topology, leads to significant improvement in performance and stability. The proposed cells' yield outperforms that of register file like cells as well as other literature cells. The usage of a larger number of cells on bitlines through statistical simulations indicates that the new cells improve the array efficiency for domino based designs. The extension of the work to 32 nm technology shows the scalability of these cells with lower operating voltage, compared with conventional 6T/8T cells. Hardware based key features include improved read performance/stability, half select stability, and the ability to operate with single read and write wordline over register file like 8T cell. The measured access time improvement is shown to be more than 15% and a Vcsmin reduction of 170 mV is demonstrated at Vdd = 1 V.
Robust optimisation formulations for the design of an electric machine (2018)

In this study, two formulations for the robust optimisation of the size of the permanent magnet in a synchronous machine are discussed. The optimisation is constrained by a partial differential equation to describe the electromagnetic behaviour of the machine. The need for a robust optimisation procedure originates from the fact that optimisation parameters have deviations. The first approach, i.e. worst‐case optimisation, makes use of local sensitivities. The second approach takes into account expectation values and standard deviations. The latter are associated with global sensitivities. The geometry parametrisation is elegantly handled thanks to the introduction of an affine decomposition. Since the stochastic quantities are determined by tools from uncertainty quantification (UQ) and thus require a lot of finite element evaluations, model order reduction is used in order to increase the efficiency of the procedure. It is shown that both approaches are equivalent if a linearisation is carried out. This finding is supported by the application on an electric machine. The optimisation algorithms used are sequential quadratic programming, particle swarm optimisation and genetic algorithm. While both formulations reduce the size of the magnets, the UQ‐based optimisation approach is less pessimistic with respect to deviations and yields smaller magnets.
Assesment of Anticarcinogenic Activities of the Soft Coral Sarcophyton Glaucum Extract on Mouse Leukemia In Vivo and In vitro (2017)

Marine environment biodiversity opens up new horizons in the quest for bioactive compounds that could be utilized as antitumor agents. Soft Coral Sarcophyton glaucum is an important folk medicinal marine. It has anti-oxidant, anticarcinogenic. The objectives of present study are to investigatimg in vitro the antiproliferative activity of sarcophine extract on mouse Leukemia cells (L1210), also, we shall evaluate in vivo the antitumor activity of the soft coral S. glaucum extract against Mouse Leukemia cells (L1210), on mice (Swiss albino mice). The antiproliferative and cytotoxic activities of the S. glaucum were determined using the trypan blue dye exclusion and the WST-1 cell proliferation tests. The underlying possible mechanism of cell death was investigated whether it is necrotic or apoptotic by single cell gel electrophoresis (comet assay) and dual acridine orange/ethidium bromide (AO/EB) staining. The antitumor activity of the S. glaucum extract against mouse leukemia cell line, L1210, grown as ascites in mouse model. In vitro Results showed that S. glaucum inhibited L1210 cancer cells proliferation and induced apoptosis and that the apoptotic activities. The mechanism underlying cell death was due to induction of apoptosis, which was associated by DNA damage and morphological changes of the treated cells. In vivo study indicated that S. glaucum has ability to suppress cancer progression in treated animals. These findings indicate that the S. glaucum extract can be a candidate agent for fighting cancer.
