Sensor Fusion in Computer Vision (2007)

Sensor fusion has been an active area of research in the field of computer vision for over two decades. Early approaches to sensor fusion were focused on the recovery of the three-dimensional scene structure from two short baseline cameras which was considered to be similar to the human vision system. Recently with the availability of sensors of various modalities, computer vision researchers have started looking into these new sensory data for the solution of automated understanding of the scene content. In this paper, an outline of some of the most common sensor fusion techniques is provided. Although no priority is given to one technique over the others, we selected only a handful techniques that are related to sensor fusion in the context of urban city modeling.
ADHD: Disorder or Discipline Problem? (2001)

Treating children for attention deficit hyperactivity disorder (ADHD) with stimulant medications predisposes them to substance abuse, according to Peter Breggin in his letter to Science (“Questioning the treatment for ADHD,” 26 Jan., p. [595][1]). In support, he cites one article, but does not
Intermixing of Dual Media and Multimedia Granular Filters (1975)

The use of mixed‐media filters results in longer filter cycles and, in some cases, better filtrate quality than single‐media sand filters. Unfortunately, during backwashing the stratification of the sand particles in mixed‐media filters is rearranged. In this study two models for predicting the degree of intermixing between different media at proposed backwash rates and water temperatures were examined.

Genome-wide analysis of DNA methylation in rat lungs with lipopolysaccharide-induced acute lung injury (2013)

Acute lung injury and acute respiratory distress syndrome (ALI/ARDS) are associated with high morbidity and mortality in patients, however, the precise pathogenesis of ALI/ARDS remains unknown. Lipopolysaccharide (LPS) exhibits a number of critical functions and may be associated with the DNA methylation of genes in the lungs. In the present study a genome‑wide analysis of DNA methylation was performed in rat lungs with LPS‑induced ALI/ARDS. Normal and LPS‑induced lung tissues with ALI were analyzed using methylated DNA immunoprecipitation and a rat DNA methylation promoter plus CpG island microarray and the candidate genes were validated by quantitative reverse transcriptase polymerase chain reaction (qRT‑PCR). Aberrant DNA methylation of the promoter regions of 1,721 genes and the CpG islands of 990 genes was identified when normal lung tissues and lung tissues with LPS‑induced ALI/ARDS were compared. These genes were commonly located on chromosomes 1, 3, 5, 7 and 10 (P<0.01). Methylation level and CpG density were compared and it was found that genes associated with high CpG density promoters had a high ratio of methylation. Furthermore, we performed gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. In addition, three genes (Mapk3, Pak1 and Rac2) were validated in the control and lung tissues with ALI by RT‑PCR. The results indicate that aberrant DNA methylation of lung tissues may be involved in the pathophysiology of LPS‑induced ALI/ARDS. Future studies are required to evaluate the therapeutic and prognostic value of the current novel observations in ALI/ARDS.

A photosensitive low-k interlayer-dielectric film for ULSIs (2002)

A photosensitive interlayer dielectric film was developed for a future ULSI multilevel interconnect technology. A photosensitive methylsilsesquiazane with a low-dielectric constant was synthesized. It could be patterned by use of either electron beam lithography or ultraviolet lithography. It is demonstrated that the smallest feature size of 50 nm for damascene lines and via holes could be directly patterned in the films by the electron beam lithography.
Design Considerations For A Flexible High-Resolution Film Recording System (1981)

The High Resolution Film Recording System (HRFRS), recently delivered to NASA/Goddard Space Flight Center by RCA, is uniquely characterized by full flexibility in: resolution (1,000 to 20,000 pixels/scan), line rate (15-350' lines/sec), data rate (0.5 to 20 Mbit/sec), optical spot size (10 itaM to 200 pm), pixel aspect ratio (0.5 to 2.0), and frame aspect ratio (0.5 to 2.0). This flexibility is designed to accommodate the specific characteristics of all NASA's satellite, imaging sensors of the 1970s and 1980s. RCA renamed this system Operation Laser Beam Recorder (OLBR) to reflect the production environment in which this versatile, high performance image recorder must operate. Design tech niques and objectives are presented which meet the required flexibilities while maintaining simplicity of design, repeatability, quality of performance, and operability in an image production environment. Human factors, careful partitioning of subsystems, and innovative design techniques are successfully employed to yield a versatile film recording system with a minimum of operational complexity..
Stability of iridium oxide films in high temperature, 200-250 degrees , solutions (1990)

The stability of reactively sputtered iridium oxide films on alumina substrates on exposure to pH 4, 7, and 10 solutions at 200 degrees C and 250 degrees C is examined. The exposures were made in a Teflon-lined bomb. The results of over 50 tests, cycling pH between 2 and 10 before and after exposure, are discussed. Changes of E degrees , the formed potential, and the slope were most severe under acidic conditions at 250 degrees C. The most severe conditions also caused film breakdown and loss of adhesion to the substrate. The incorporation of ion-assisted deposition in the fabrication of the films led to improved adherence under the most severe conditions of exposure. The results indicated similar behavior for films deposited at 500 K (crystalline) and those deposited at room temperature (amorphous).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

EEG-fMRI in the preoperative work-up for epilepsy surgery (2007)

Epilepsy surgery requires precise localization of the epileptic source. EEG-correlated functional MRI (EEG-fMRI) is a new technique showing the haemodynamic effects of interictal epileptiform activity. This study assesses its potential added value in the presurgical evaluation of patients with complex source localization. Adult surgical candidates considered ineligible because of an unclear focus and/or presumed multifocality on the basis of EEG underwent EEG-fMRI. Interictal epileptic discharges (IEDs) in the EEG during fMRI were identified by consensus between two observers. Topographically distinct IED sets were analysed separately. Only patients with significant, positive blood oxygen level-dependent (BOLD) responses that were topographically related to the EEG were re-evaluated for surgery. Forty-six IED sets from 29 patients were analysed. In eight patients, at least one BOLD response was significant, positive and topographically related to the IEDs. These patients were rejected for surgery because of an unclear focus (n = 3), presumed multifocality (n = 2) or a combination of both (n = 3). EEG-fMRI improved localization in four out of six unclear foci. In patients with presumed multifocality, EEG-fMRI advocated one of the foci in one patient and confirmed multifocality in four out of five patients. In four patients EEG-fMRI opened new prospects for surgery and in two of these patients intracranial EEG supported the EEG-fMRI results. In these complex cases, EEG-fMRI either improved source localization or corroborated a negative decision regarding surgical candidacy. It is thus a valuable tool in the presurgical evaluation of patients. Guidelines for the use of EEG-fMRI in clinical practice are proposed.
Synthesis and characterization of platinum(ii) di-ynes and poly-ynes incorporating ethylenedioxythiophene (EDOT) spacers in the backbone (2011)

A series of trimethylsilyl-protected di-alkynes incorporating 3,4-ethylenedioxythiophene (EDOT) linker groups Me(3)Si-C≡C-R-C≡C-SiMe(3) (R = ethylenedioxythiophene-3,4-diyl 1a, 2,2'-bis-3,4-ethylenedioxythiophene-5,5'-diyl 2a, 2,2',5',2''-ter-3,4-ethylenedioxythiophene-5,5''-diyl 3a) and the corresponding terminal di-alkynes, H-C≡C-R-C≡C-H 1b-2b has been synthesized and characterized and the single crystal X-ray structure of 1a has been determined. CuI-catalyzed dehydrohalogenation reaction between trans-[(Ph)(Et(3)P)(2)PtCl] and the terminal di-alkynes 1b-2b in (i)Pr(2)NH/CH(2)Cl(2) (2:1 mole ratio) gives the Pt(II) di-ynes trans-[(Et(3)P)(2)(Ph)Pt-C≡C-R-C≡C-Pt(Ph)(Et(3)P)(2)] 1M-2M while the dehydrohalogenation polycondensation reaction between trans-[((n)Bu(3)P)(2)PtCl(2)] and 1b-2b (1:1 mole ratio) under similar reaction conditions affords the Pt(II) poly-ynes trans-[Pt(P(n)Bu(3))(2)-C≡C-R-C≡C-](n)1P-2P. The di-ynes and poly-ynes have been characterized spectroscopically and, for 1M and 2M, by single-crystal X-ray which confirms the "rigid rod" di-yne backbone. The materials possess excellent thermal stability, are soluble in common organic solvents and readily cast into thin films. Optical absorption spectroscopic measurements reveal that the EDOT spacers create stronger donor-acceptor interactions between the platinum(II) centres and conjugated ligands along the rigid backbone of the organometallic polymers compared to the related non-fused and fused oligothiophene spacers.

Gamma-Glutamylpolyamine Synthetase GlnA3 Is Involved in the First Step of Polyamine Degradation Pathway in Streptomyces coelicolor M145 (2017)

<i>Streptomyces coelicolor</i> M145 was shown to be able to grow in the presence of high concentrations of polyamines, such as putrescine, cadaverine, spermidine, or spermine, as a sole nitrogen source. However, hardly anything is known about polyamine utilization and its regulation in streptomycetes. In this study, we demonstrated that only one of the three proteins annotated as glutamine synthetase-like protein, GlnA3 (SCO6962), was involved in the catabolism of polyamines. Transcriptional analysis revealed that the expression of <i>glnA3</i> was strongly induced by exogenous polyamines and repressed in the presence of ammonium. The Δ<i>glnA3</i> mutant was shown to be unable to grow on defined Evans agar supplemented with putrescine, cadaverine, spermidine, and spermine as sole nitrogen source. HPLC analysis demonstrated that the Δ<i>glnA3</i> mutant accumulated polyamines intracellularly, but was unable to degrade them. In a rich complex medium supplemented with a mixture of the four different polyamines, the Δ<i>glnA3</i> mutant grew poorly showing abnormal mycelium morphology and decreased life span in comparison to the parental strain. These observations indicated that the accumulation of polyamines was toxic for the cell. An <i>in silico</i> analysis of the GlnA3 protein model suggested that it might act as a gamma-glutamylpolyamine synthetase catalyzing the first step of polyamine degradation. GlnA3-catalyzed glutamylation of putrescine was confirmed in an enzymatic <i>in vitro</i> assay and the GlnA3 reaction product, gamma-glutamylputrescine, was detected by HPLC/ESI-MS. In this work, the first step of polyamine utilization in <i>S. coelicolor</i> has been elucidated and the putative polyamine utilization pathway has been deduced based on the sequence similarity and transcriptional analysis of homologous genes expressed in the presence of polyamines.
Advances in Shaping of Metal–Organic Frameworks for CO2 Capture: Understanding the Effect of Rubbery and Glassy Polymeric Binders (2018)

Development of advanced CO2 capture physical adsorbents in powdered form is a key step, nevertheless their transformation into particulates is a process of paramount importance for their deployment and implementation in the real-world applications. Herein we report a facile and quick shaping process of one of the best solid-state materials from the class of metal–organic frameworks (MOFs) for CO2 capture at a concentration below 15%, that is, NbOFFIVE-1-Ni driven mainly by strong but purely physical based adsorption. Purposely, NbOFFIVE-1-Ni powders were transformed into shaped bodies using select polymers as binders and their associated CO2 capture properties were thoroughly evaluated before and after shaping. Markedly, we have selected two distinct polymers, namely a rubbery polymer (polyethelyneglycol = PEG) and a glassy polymer (poly(methyl methacrylate) = PMMA). To corroborate the universality of our shaping strategy, we indeed successfully made MOF beads with high mechanical stability based on well-known MOFs like UiO-66, ZIF-8, and HKUST-1. Prominently, the results show that the glassy polymer is a better binder than the rubbery polymer, offering the requisite high mechanical stability with comparatively minimal alteration in gas adsorption upon loading of 10% polymer.

Activation energy study of electron transport in high performance short wavelengths quantum cascade lasers (2010)

We present a method to study current paths through quantum cascade lasers (QCLs). The temperature dependence of the current is measured at a fixed voltage. At low temperatures we find activation energies that correspond to the energy difference between the injector ground state and the upper laser level. At higher temperatures additional paths with larger activation energies are found. Application of this method to high performance QCLs based on strained InGaAs/InAlAs quantum wells and barriers with different band-offsets allows us to identify individual parasitic current paths through the devices. The results give insight into the transport properties of quantum cascade lasers thus providing a useful tool for device optimization.
The Isomerization of Aziridine Derivatives (1962)

Abstract Derivatives of aziridine or ethylenimine are isomerized by acids, nucleophilic reagents, or pyrolysis. All of the isomerizations reported so far are ring‐opening reactions, predominantly involving cleavage of the carbon‐nitrogen bond of the ring, although a few isomerizations are known in which the carbon‐carbon bond of the ring is broken. Isomerization of appropriate aziridine derivatives provides useful synthetic pathways leading to heterocyclic systems such as oxazolines, imidazolines (and related systems), imidazolidinoes, thiazolines, pyrazolines, and triazolines. Other isomerizations form N‐unsaturated amides, anils, and isocyanates.

Estrogen‐Associated Genes in Uterine Leiomyoma (2001)

Uterine leiomyomas or fibroids are classified as a benign uterine disease in that the polyps display no malignant growth. However, uterine leiomyomas are a leading cause of morbidity, infertility, and hysterectomy in women. Since leiomyomas are known to be sensitive to estrogen for their growth, we have examined uterine genes known to be estrogen responsive in affected and unaffected uterine tissue. This information will be useful in determining the contribution, if any, of hormonally active environmental chemicals to this highly prevalent reproductive disorder.

Infection Rate for Single Lumen v Triple Lumen Subclavian Catheters (1988)

An infection rate was calculated for all subclavian catheters inserted during a 12-month period. The overall, single lumen, and triple lumen infection rates were 1.7% (42/2,431), 0.4% (8/1,936), and 6.9% (34/495), respectively. After excluding single lumen catheters in patients in a surgical cardiovascular unit who appeared to have a decreased risk of infection, the overall, single lumen, and triple lumen rates were 3.7% (42/1,140), 1.2% (8/645), and 6.9% (34/495), respectively. Within this group, 11.8% (28/237) of the catheters used for total parenteral nutrition (TPN) were infected, whereas 1.6% (14/903) of the non-TPN catheters were infected. Of patients receiving total parental nutrition through a triple lumen catheter, 14.5% (25/172) became infected, whereas 4.6% (3/65) of the patients receiving total parental nutrition through a single lumen catheter became infected. Single and triple lumen patient groups appeared comparable based on average age, death rate, immunosuppression, underlying disease, and duration of catheterization, but the risk of infection was approximately three times greater for patients receiving total parental nutrition through a triple lumen catheter.
Commutation Torque Ripple Reduction Strategy of Z-Source Inverter Fed Brushless DC Motor (2016)

Based on the Z-source inverter, this paper proposes a novel commutation torque ripple reduction strategy for brushless DC motor (BLDCM). The proposed strategy employs the same modulation mode in both the normal conduction period and the commutation period, and the commutation torque ripple is reduced by regulating the shoot-through vector and active vector duty cycles. The proposed detection method acquires the end point of commutation by comparing the clamped terminal voltages with reference zero level, and the signal-noise-ratio of the detection is improved by avoiding the attenuation of the terminal voltages. Furthermore, a certain pulse width of the shoot-through vector can not only reduce the commutation torque ripple but also provide a new opportunity to detect the end point of commutation. Moreover, Z-source inverter provides the buck-boost ability for BLDCM drive system, then the dc voltage utilization can be improved, and the safety of the drive system can also be improved. In addition, this paper analyzes the terminal voltages during each vector. The experimental results verify the correctness of the theories and the effectiveness of the proposed approach.

Enhancing student retention rates on open non-formal online language learning courses (2019)

Open non-formal online courses are becoming increasingly popular as a self-paced option for learners. However, the attrition rates for such courses, similar to other online options such as MOOCs, can be high. In this exploratory research study two teacher-researchers reflect on and analyse their experience of creating open non-formal online courses for English language learners, and go on to suggest several practical techniques to decrease the number of students that may drop out. Firstly, the wider reasons why online students may drop out, such as insufficient feedback or the impact of cognitive overload, are discussed and several ways are suggested to get around these issues. Secondly, various principles of instructional design such as keeping lessons consistent but variable, relevant, and divided into manageable chunks are recommended. Finally, a number of ways that videos can be made more engaging are shown, especially focusing on how a talking head can be best portrayed in order to give the clearest information and develop a more personalised teacher presence. Although the data and analysis are focused on open non-formal online courses the findings and discussion are of relevance to other forms of online instruction and multimedia learning.
Detection of Shallow Dislocations on 4H-SiC Substrate by Etching Method (2011)

Correlation between dislocation types in epitaxial 4H-SiC and etch pit types on the 4H-SiC wafer surface were investigated by etch pit method and transmission electron microscope. Shallow dislocation on the wafer was found to form round pit without core. The shallow dislocation was estimated half-loop type in wafer and this estimation explains that step-ow growth converts half-loop dislocation into complex dislocation composed by threading dislocation and basal plane dislocation.
