SIGNAL DECOMPOSITION AND ANALYSIS FOR THE IDENTIFICATION OF PERIODIC AND ANOMALOUS PHENOMENA IN RADON TIME-SERIES (2017)

This work concerns continuous monitoring of radon and thoron specific activity in soil gas within the framework of identifying possible anomalies. It is based on the analysis of a medium-term data record obtained from soil gas in an area of geophysical interest. The RaMonA spectrometric system is also used to measure the climatic parameters and a specific analysis of the alpha spectra is performed to better determine the alpha lines intensity. Since radon emission is also influenced by meteorological parameters, it is mandatory to differentiate the changes due to the deep phenomena. Different procedures are utilized to reach the above objective: statistical analysis using the Empirical Mode Decomposition technique, the Multiple Linear Regression method and the Remote Radon Estimation by using of the thoron trend to eliminate the locally produced radon fraction. The results of such methods are compared to recognize and to highlight radon anomalies.
Mosaic multispectral focal plane array cameras (2004)

Mosaic technology has gained considerable popularity and has become mainstay in commercial digital color cameras. In a mosaicked sensor, each pixel detector is covered with a wavelength-specific optical filter. Since only one spectral band is sensed at each pixel, the other bands must be estimated from neighboring pixels. In the commercial digital color cameras, sophisticated algorithms have been developed to perform this estimation, based upon properties of the human visual system to minimize artifacts. To expand this technology for use in military applications such as missiles and smart ordnance, various modifications need to be made. Two of the bigger problems are the choice of spectral sensitivities for the filters and the pattern used in the mosaic. We propose a novel seven-band setup for multispectral imaging systems along with a choice of spectral sensitivities that "best" distinguish target from clutter in an information theoretic sense. These ideas are illustrated with hyperspectral visible/near-infrared images taken by the AVIRIS sensor. Following the image-capture stage, the display of these multispectral images on a three-channel display is also addressed.
The FLAMINGOS-2 early science surveys and the GTC (2007)

"Upon commissioning on Gemini South, FLAMINGOS-2 will be one of the most powerful wide-field near-infraredimagers and multi-object spectrographs ever built for use on 8-meter-class telescopes. In order to take bestadvantage of the strengths of FLAMINGOS-2 early in its life cycle, the instrument team has proposed touse 21 nights of Gemini guaranteed time in 3 surveys { the FLAMINGOS-2 Early Science Surveys (F2ESS).The F2ESS will encompass 3 corresponding science themes the Galactic Center, galaxy evolution, and starformation. The extragalactic survey plays an important role in the planning of EMIR/GTC observations forthe GOYA project, and the Galactic Center survey is a precursor for key planned scientific observations withFRIDA/GTCAO. I will review the status of FLAMINGOS-2, the F2ESS surveys, the additional Gemini GenesisSurvey, and their relationship to and impact on GTC science."
6-Arylcoumarin as a Scaffold of Photofunctional Molecules with OFF–ON–OFF Type Regulation (2020)

Coumarin has been utilized as a core structure of photofunctional molecules, such as fluorescent sensors and photoremovable protecting groups. Here, we show that the 6-arylcoumarin moiety can provide OFF-ON-OFF type regulatory functionality for such compounds. To illustrate its utility, we synthesized a coumarin derivative bearing two phenolic hydroxy groups at 7-position and on 6-aryl group as a fluorescent sensor showing an OFF-ON-OFF change in fluorescence intensity in response to an increase in pH from a strongly acidic condition. Further, we show that the efficiency of photoreaction of other derivatives with the same hydroxyl groups is switched from "OFF" at pH 3 and 6 to "ON" at pH 9 and then to OFF at pH 12, enabling their application as switchable photoremovable protective groups. These features arise from sequential deprotonation of two hydroxyl groups: the monoanionic form is responsible for the photoinduced fluorescence and photoreaction.

Herpes Simplex Virus 1 Infection of Tree Shrews Differs from That of Mice in the Severity of Acute Infection and Viral Transcription in the Peripheral Nervous System (2015)

Herpes simplex viruses (HSVs) establish lifelong infection in more than 80% of the human population, and their reactivation leads to oral and genital herpes. Currently, rodent models are the preferred models for latency studies. Rodents are distant from primates and may not fully represent human latency. The tree shrew is a small mammal, a prosimian primate, indigenous to southwest Asia. In an attempt to further develop the tree shrew as a useful model to study herpesvirus infection, we studied the establishment of latency and reactivation of HSV-1 in tree shrews following ocular inoculation. We found that the latent virus, which resides in the sensory neurons of the trigeminal ganglion, could be stress reactivated to produce infectious virus, following explant cocultivation and that spontaneous reactivation could be detected by cell culture of tears. Interestingly, the tree shrew model is quite different from the mouse model of HSV infection, in that the virus exhibited only a mild acute infection following inoculation with no detectable infectious virus from the sensory neurons. The mild infection may be more similar to human infection in that the sensory neurons continue to function after herpes reactivation and the affected skin tissue does not lose sensation. Our findings suggest that the tree shrew is a viable model to study HSV latency.
High-speed solar-blind UV photodetectors using high-Al content Al0.64Ga0.36N/Al0.34Ga0.66N multiple quantum wells (2016)

Abstract We demonstrate high-external quantum efficiency (∼50%) solar-blind AlGaN p–n junction photodetectors with high-Al content multiple quantum wells (MQWs). A peak responsivity of 0.1 A/W at 250 nm, which falls &gt;10 3 by 280 nm, indicates that the optical absorption is dominated by the MQW structures. At a reverse bias of 0.5 V, the dark current is &lt;0.1 pA. The readout RC-limited time response is measured as 0.4 µs, and an achievable detector RC-limited time response of 2 ns is estimated. The devices do not show internal gain, which accounts for their high speed.
Stable Isotope Probing of an Algal Bloom To Identify Uncultivated Members of the Rhodobacteraceae Associated with Low-Molecular-Weight Polycyclic Aromatic Hydrocarbon Degradation (2011)

Polycyclic aromatic hydrocarbon (PAH)-degrading bacteria associated with an algal bloom in Tampa Bay, FL, were investigated by stable isotope probing (SIP) with uniformly labeled [¹³C]naphthalene. The dominant sequences in clone libraries constructed from ¹³C-enriched bacterial DNA (from naphthalene enrichments) were identified as uncharacterized members of the family Rhodobacteraceae. Quantitative PCR primers targeting the 16S rRNA gene of these uncultivated organisms were used to determine their abundance in incubations amended with unlabeled naphthalene and phenanthrene, both of which showed substantial increases in gene copy numbers during the experiments. As demonstrated by this work, the application of uniformly ¹³C-labeled PAHs in SIP experiments can successfully be used to identify novel PAH-degrading bacteria in marine waters.
Nb/sub 3/Ge-based 1-m power-transmission cable: material development, cable fabrication, and cable-performance tests. Final report, July 1981 (1981)

Since its discovery in 1973 as the superconductor with the highest known transition temperature (T/sub c/ greater than or equal to 23 K), Nb/sub 3/Ge has offered the possibility of operating temperatures greater than or equal to 14 K, for superconducting devices. For application to the transmission of electric power, higher operating temperatures imply increased efficiency and lower capital costs. In the first two phases of our program to develop a Nb/sub 3/Ge conductor for power transmission applications we developed a chemical vapor deposition CVD process for producing long continuous lengths of Nb/sub 3/Ge-clad tape conductors with critical current densities J/sub c/ and low ac losses suitable for power transmission at T greater than or equal to 12 K. In this report, we describe the fabrication and testing of a 1-m-long coaxial cable constructed from 87 m of our Nb/sub 3/Ge-clad tape. Short sample measurements indicated that all of this tape exceeded the specification that J/sub c/ (13.8 K) greater than or equal to 1.8 x 10/sup 6/ A/cm/sup 2/. The cable was wound in the double-helix design of the Brookhaven National Laboratory, BNL, power transmission project. AC current tests were performed at BNL where the cable carried the designmore » current amplitude of 6000 A but exhibited ac losses from 7 to 13 K that were 50 to 100 greater than were expected from short sample measurements. These losses were attributed to a combination of instrumental problems associated with ac loss measurements in 1-m cables of the double helix design, end effects, and possible tape damage. The results of a materials development program aimed at improving the superconducting performance of our Nb/sub 3/Ge material is also described.« less
Efficient optimistic concurrency control using loosely synchronized clocks (1995)

This paper describes an efficient optimistic concurrency control scheme for use in distributed database systems in which objects are cached and manipulated at client machines while persistent storage and transactional support are provided by servers. The scheme provides both serializability and external consistency for committed transactions; it uses loosely synchronized clocks to achieve global serialization. It stores only a single version of each object, and avoids maintaining any concurrency control information on a per-object basis; instead, it tracks recent invalidations on a per-client basis, an approach that has low in-memory space overhead and no per-object disk overhead. In addition to its low space overheads, the scheme also performs well. The paper presents a simulation study that compares the scheme to adaptive callback locking, the best concurrency control scheme for client-server object-oriented database systems studied to date. The study shows that our scheme outperforms adaptive callback locking for low to moderate contention workloads, and scales better with the number of clients. For high contention workloads, optimism can result in a high abort rate; the scheme presented here is a first step toward a hybrid scheme that we expect to perform well across the full range of workloads.
Surface Tension Prediction of Vegetable Oils Using Artificial Neural Networks and Multiple Linear Regression (2014)

The surface tension is one of the main properties for characterization of the quality of the fuel atomization process for its use in a diesel engine. There is a lack of published information about the values of surface tension of vegetable oils. The aim of this research is to obtain a mathematical model based on physical properties that establishes a relationship between the surface tensions of different vegetable oils and their fatty acid composition. For this reason, from literature reports, experimental data of oils related to the surface tensions was collected. Knowing that surface tension as a function of temperature, a total amount of 15 oils from different feedstocks at 20 °C was selected. The obtained models were developed based in the use of artificial neural networks and multiple linear regressions fits, based on the experimental data available in the literature. Also, the obtained models present a good correlation between surface tension and the fatty acid composition, with a 95% of confidence interval and coefficient of correlation higher than 0,95. The coefficient of correlation obtained shown a high correlation between the analyzed variables. According to the obtained results, the proposed models are a useful tool for the surface tension estimation from the oils fatty acid composition.
Endotoxin in vitro interactions with human neutrophils: depression of chemiluminescence, oxygen consumption, superoxide production, and killing (1979)

Endotoxin was shown to depress neutrophil bactericidal activity while enhancing Nitro Blue Tetrazolium reduction and hexose monophosphate shunt activity. Separation of bactericidal action from oxidative metabolism suggests that the effect of endotoxin might involve the formation of reactive oxygen radicals such as superoxide. Chemiluminescence often accompanies metabolic activation of polymorphonuclear neutrophils (PMNs). However, human PMNs did not show chemiluminescence when challenged with endotoxin (lipopolysaccharide; LPS) or lipid A. Superoxide formation was also unaffected by endotoxin. In contrast, preincubation of PMNs with LPS for 30 min produced significant depression of chemiluminescence, oxygen consumption, and superoxide formation. Decreased chemiluminescence was not the result of complement consumption. In a cell-free system, superoxide was not scavenged by LPS, nor did LPS stimulate superoxide dismutase. Oxidase enzymes for reduced nicotinamide adenine dinucleotide or reduced nicotinamide adenine dinucleotide phosphate harvested from broken cells were not affected by LPS. The toxicity of LPS may reside in its ability to activate the PMNs while simultaneously blocking bactericidal capacity.
Learning-Based Uplink Interference Management in 4G LTE Cellular Systems (2014)

LTE's uplink (UL) efficiency critically depends on how the interference across different cells is controlled. The unique characteristics of LTE's modulation and UL resource assignment poses considerable challenges in achieving this goal because most LTE deployments have 1:1 frequency reuse, and the uplink interference can vary considerably across successive time-slots. In this paper, we propose LeAP, a measurement data-driven machine learning paradigm for power control to manage uplink interference in LTE. The data-driven approach has the inherent advantage that the solution adapts based on network traffic, propagation, and network topology, which is increasingly heterogeneous with multiple cell-overlays. LeAP system design consists of the following components: 1) design of user equipment (UE) measurement statistics that are succinct, yet expressive enough to capture the network dynamics, and 2) design of two learning-based algorithms that use the reported measurements to set the power control parameters and optimize the network performance. LeAP is standards-compliant and can be implemented in a centralized self-organized networking (SON) server resource (cloud). We perform extensive evaluations using radio network plans from a real LTE network operational in a major metro area in the US. Our results show that, compared to existing approaches, LeAP provides <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$4.9\times$</tex> </formula> gain in the 20th percentile of user data rate, <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$3.25\times$</tex> </formula> gain in median data rate.
Lithium-ion Battery State of Health Estimation Using Ah-V Characterization (2011)

The battery state of health (SOH) is a measure of the battery’s ability to store and deliver electrical energy. Typical SOH methods characterize either the battery power or energy. In this paper, new SOH estimation methods are investigated based on the battery energy represented by the Ampere-hour throughput (Ah). The methods utilize characteristics of the Ah to estimate the battery capacity or the useable energy for state of health estimation. Three new methods are presented and compared. The simulation results indicate the effectiveness of the methods for state of health estimation.
A Sensitive Method to Quantify Senescent Cancer Cells (2013)

Human cells do not indefinitely proliferate. Upon external and/or intrinsic cues, cells might die or enter a stable cell cycle arrest called senescence. Several cellular mechanisms, such as telomere shortening and abnormal expression of mitogenic oncogenes, have been shown to cause senescence. Senescence is not restricted to normal cells; cancer cells have also been reported to senesce. Chemotherapeutical drugs have been shown to induce senescence in cancer cells. However, it remains controversial whether senescence prevents or promotes tumorigenesis. As it might eventually be patient-specific, a rapid and sensitive method to assess senescence in cancer cell will soon be required. To this end, the standard β-galactosidase assay, the currently used method, presents major drawbacks: it is time consuming and not sensitive. We propose here a flow cytometry-based assay to study senescence on live cells. This assay offers the advantage of being rapid, sensitive, and can be coupled to the immunolabeling of various cellular markers.
A randomised placebo-controlled multicentre trial of intravenous semapimod HCl for moderate to severe Crohn's disease (2010)

Single and 3 day dosing of semapimod (< or = 180 mg) was ineffective for the treatment of moderate to severe CD. However, cumulative dosing > or = 360 mg was associated with decreased CDAI in a limited number of patients.
Subsidence monitoring within the Athens Basin (Greece) using space radar interferometric techniques (2006)

Abstract The application of conventional SAR Interferometry (InSAR) together with the two techniques of subcentimeter accuracy, the Stacking and the Permanent Scatterers (PS) Interferometry, were used to study the ground deformation in the broader area of Athens for the period 1992 to 2002. Using the Stacking interferometric method, 55 ERS-1&amp;2 SAR scenes, between 1992 and 2002, were acquired producing 264 differential interferograms. Among these only 60 were finally selected as fulfilling certain criteria. The co-seismic deformation associated with the Athens Earthquake (M w = 5.9, September 7, 1999) was excluded from the analytical procedure in an attempt to present results of only aseismic character. In total ground subsidence results of about 12 mm in the southern suburbs of Athens, but higher value of about 40 mm in the northern ones for the period 1992–2002. Based on the PS technique, a precise average annual deformation rate-map was generated for the period 1992–1999, ending just before the Athens earthquake event. Both circular and elongated-shape areas of subsidence are recognizable especially in the northern part of the Athens Basin (3–4 mm/yr), as well as at its southern part (1–3 mm/yr). In addition, a rate of 2–3 mm/yr is also yielded for some part of the Athens city center. Subsidence rates of 1–2 mm/yr are measured at the western part of the basin over an area of old mining activities, and around the newly built Syntagma Metro Station. The correlation of the observed deformation patterns with respect to the spatial distribution of water pumping, older mining activities, metro line tunneling and other local geological parameters is examined and discussed.
Correlating Phase Behavior with Photophysical Properties in Mixed‐Cation Mixed‐Halide Perovskite Thin Films (2019)

Abstract Mixed cation perovskites currently achieve very promising efficiency and operational stability when used as the active semiconductor in thin‐film photovoltaic devices. However, an in‐depth understanding of the structural and photophysical properties that drive this enhanced performance is still lacking. Here the prototypical mixed‐cation mixed‐halide perovskite (FAPbI 3 ) 0.85 (MAPbBr 3 ) 0.15 is explored, and temperature‐dependent X‐ray diffraction measurements that are correlated with steady state and time‐resolved photoluminescence data are presented. The measurements indicate that this material adopts a pseudocubic perovskite α phase at room temperature, with a transition to a pseudotetragonal β phase occurring at ≈260 K. It is found that the temperature dependence of the radiative recombination rates correlates with temperature‐dependent changes in the structural configuration, and observed phase transitions also mark changes in the gradient of the optical bandgap. The work illustrates that temperature‐dependent changes in the perovskite crystal structure alter the charge carrier recombination processes and photoluminescence properties within such hybrid organic–inorganic materials. The findings have significant implications for photovoltaic performance at different operating temperatures, as well as providing new insight on the effect of alloying cations and halides on the phase behavior of hybrid perovskite materials.
Study on Quality Improvement of HMM-Based Synthesized Voices Using Asymmetric Bilinear Model (2016)

Hidden Markov model (HMM)-based synthesized voices are intelligible but not natural especially under limited-data conditions due to over-smoothed speech spectra. Improving naturalness is a critical problem of HMM-based speech synthesis. One solution is to use voice conversion techniques to convert over-smoothed spectra to natural spectra. Although conventional conversion methods transform speech spectra to natural ones to improve naturalness, they cause unexpected distortions in the intelligibility of synthesized speech. The aim of the study is to improve naturalness without reducing the intelligibility of synthesized speech by employing our novel asymmetric bilinear model (ABM) to separate the intelligibility and naturalness of synthesized speech. In the study, our ABM was implemented on the modulation spectrum domain of Mel-cepstral coefﬁcient (MCC) sequences to enhance the ﬁne structure of spectral parameter trajectory generated from HMMs. Subjective evaluations carried out on English data conﬁrmed that the achieved naturalness of the method using the ABM involving singular value decomposition (SVD) was competitive with other methods under large-data conditions and outperformed other methods under limited-data conditions. Moreover, modiﬁed rhyme test (MRT) showed that the intelligibility of synthesized speech was well preserved with our method.
Interaction of mobile camera devices with physical maps (2006)

Abstract. Traditional paper-based maps are still superior to their digital counterparts used on mobile devices in several ways. They provide high-resolution, large-scale information with zero power consumption. On the other hand digital maps provide personalized and dynamic information on request, but suffer from small outer scales and low resolutions. In this work we try to combine the advantages of both by using mobile camera devices (such as smartphones ore PDA) as a map-referenced magic lens that displays geo-referenced information on top of the physical map. We will mainly focus on the interaction schemes that arise from using mobile camera devices with physical maps and briefly explain how the device tracking over existing physical maps can be realized. 1
