An unusual breeding aggregation of frogs, with notes on the ecology of Agalychnis spurrelli Anura Hylidae (1974)

In August 1970, a breeding aggregation comprising an estimated 13,000 Agalychnis spurrelli was observed at a man-made pond on the Osa Peninsula, Puntarenas Province, Costa Rica. Apparently this extraordinarily dense breeding population was the result of ideal conditions offered by the artificial breeding site: the lack of the more effective predators (fish) in a large permanent body of water surrounded by numerous suitable oviposition sites and continuous forest which is immediately accessible for post-metamorphic dispersal. A high degree of larval success followed by normal post-metamorphic mortality, unaffected by density dependent factors, could lead to the high breeding population observed. Some males at the site were seen to scrape previously laid eggs off leaves. Additional observations and experiments demonstrated a definite parachuting ability of A. spurrelli, a behavioral and morphologic adaptation shared to a greater or lesser degree with other highly arboreal tree frogs.
The Quality Evaluation Method of Instrument Flight Procedure Design Scheme Based on Fuzzy Linguistic Assessments (2013)

The quality of Instrument Flight Procedure Design Scheme (QIFPDS) is directly related to the terminal area airspace capacity, quality, efficiency of air traffic management, and even the safety of aircraft. Hence, the evaluation of QIFPDS has great significance in real life. However, the evaluation of QIFPDS in real work is mainly done by experts through their specific knowledge and experience, which usually leads to a bias result and inevitably contains subjectivity and arbitrary defects. In this paper, a multi-attribute group decision-making method is proposed. This method makes full use of evaluation information; objectively and effectively evaluate QIFPDS. Also in this paper, a mathematical model for this method is introduced and a detailed step to solve this model is listed. At the end of this paper, an example is given to show the effectiveness and feasibility of the method. DOI:  http://dx.doi.org/10.11591/telkomnika.v11i12.3687
A Tour of Modern Image Filtering (2013)

Recent developments in computational imaging and restoration have heralded the arrival and convergence of several powerful methods for adaptive processing of multidimensional data. Examples include
Exploring Individual Differences in Raybased Selection; Strategies and Traits (2006)

User-centered design is often performed without regard to individual user differences in aptitude and experience. The methodology of this study is an anthropological and observational approach observing users performing a selection task using common virtual environment raybased techniques and analyzes the interaction through psychology aptitude tests, questionnaires and observation. The results of this study show the approach yields useful information about users even in a simple task. The study indicates correlations between performance and aptitude test and user behavior performed to overcome difficulties in the task.
Smooth Graphs for Visual Exploration of Higher-Order State Transitions (2009)

In this paper, we present a new visual way of exploring state sequences in large observational time-series. A key advantage of our method is that it can directly visualize higher-order state transitions. A standard first order state transition is a sequence of two states that are linked by a transition. A higher-order state transition is a sequence of three or more states where the sequence of participating states are linked together by consecutive first order state transitions. Our method extends the current state-graph exploration methods by employing a two dimensional graph, in which higher-order state transitions are visualized as curved lines. All transitions are bundled into thick splines, so that the thickness of an edge represents the frequency of instances. The bundling between two states takes into account the state transitions before and after the transition. This is done in such a way that it forms a continuous representation in which any subsequence of the time series is represented by a continuous smooth line. The edge bundles in these graphs can be explored interactively through our incremental selection algorithm.We demonstrate our method with an application in exploring labeled time-series data from a biological survey, where a clustering has assigned a single label to the data at each time-point. In these sequences, a large number of cyclic patterns occur, which in turn are linked to specific activities. We demonstrate how our method helps to find these cycles, and how the interactive selection process helps to find and investigate activities.
Suberoylanilide hydroxamic acid (SAHA; vorinostat) suppresses translation of cyclin D1 in mantle cell lymphoma cells (2007)

Mantle cell lymphoma (MCL) has a chromosomal translocation resulting in the expression of the cyclin D1 gene driven by the powerful enhancer of the immunoglobulin heavy chain gene, leading to uncontrolled, overexpressed cyclin D1 protein. We showed that suberoylanilide hydroxamic acid (SAHA; vorinostat), one of the histone deacetylase inhibitors derived from hydroxamic acid, caused a dramatic decrease (90%) in protein levels of cyclin D1 after 8-hour exposure to SAHA (5 muM) in MCL lines (SP49, SP53, Jeko1). mRNA levels and protein stability of cyclin D1 were minimally affected by SAHA over 8 hours. In contrast, metabolic labeling assays showed that SAHA decreased incorporation of [(35)S]methionine into cyclin D1 protein. The drug also decreased levels of phosphorylated Akt, mammalian target of Rapamycin (mTOR), and eukaryotic translation initiation factor 4E binding protein (eIF4E-BP) and lowered the cap site binding activity of eIF4E in the MCL cells. In vitro phosphatidyl inositol (PI) kinase assay demonstrated that SAHA directly inhibited kinase activity of PI 3' kinase. Taken together, SAHA caused a rapid decrease of cyclin D1 in MCL by blocking the translation of cyclin D1 by inhibiting the phosphatidylinositol 3-kinase (PI3K)/Akt/mTOR/eIF4E-BP pathway, probably by PI3K inhibition.
Celiac Disease with Mild to Moderate Histologic Changes is a Common Cause of Chronic Diarrhea in Indian Children (2005)

Coeliac disease is more common than previously believed. It presents a variable histology, and diagnoses may be missed or delayed if based only on severe enteropathies. Serology is a useful adjunct to diagnosis, and diagnostic criteria need to be developed appropriately for coeliac disease in developing countries despite limited facilities.
Measuring and understanding user comfort with resource borrowing (2004)

Resource borrowing is a common underlying approach in grid computing and thin-client computing. In both cases, external processes borrow resources that would otherwise be delivered to the interactive processes of end-users, creating contention that slows these processes and decreases the comfort of the end-users. How resource borrowing and user comfort are related is not well understood and thus resource borrowing tends to be extremely conservative. To address this lack of understanding, we have developed a sophisticated distributed application for directly measuring user comfort with the borrowing of CPU time, memory space, and disk bandwidth. Using this tool, we have conducted a controlled user study with qualitative and quantitative results that are of direct interest to the designers of grid and thin-client systems. We have found that resource borrowing can be quite aggressive without creating user discomfort, particularly in the case of memory and disk. We also describe an on-going Internet-wide study using our tool.
Autoantibodies to HLA B27 in the sera of HLA B27 patients with ankylosing spondylitis and Reiter's syndrome. Molecular mimicry with Klebsiella pneumoniae as potential mechanism of autoimmune disease. (1987)

Ankylosing spondylitis (AS) and Reiter's syndrome (RS) both show a strong correlation with the HLA B27 haplotype. We studied whether sharing of homologous amino acid sequences in the HLA B27 antigen with an invading microbe might occur, and if so, what is the biological significance of such homology. In a computer search of the Dayhoff data bank, we found a homology of six consecutive amino acids between HLA B27.1 antigen residues 72-77 and Klebsiella pneumoniae nitrogenase residues 188-193. These shared sequences are hydrophilic, suggesting locations on molecules exposed to the cell surface. Immunochemical analysis showed that 18 of 34 sera from patients with RS (53%) and 7 of 24 sera from patients with AS (29%) contained antibodies that bound to a synthesized peptide sequence representing residues 69-84 of HLA B27.1. In contrast, only 1 of 22 sera from healthy, B27+ controls (5%) contained antibodies to this peptide (p less than 0.01). Sera from three HLA B27- patients with RS did not possess antibodies to the HLA B27 peptide. Additionally, greater than 40% of HLA B27 patients with AS or RS had antibodies to Klebsiella residues 184-193, while none of the normal nonarthritic HLA B27 haplotype subjects did. Our results suggest that an autoimmune response(s) directed against HLA B27.1 may be a pathogenic mechanism in a subset of patients with AS and RS. Further, this response may initially be induced against Klebsiella pneumoniae, a microorganism that shares sequence homology with HLA B27.
Preparation and electrochromic properties of rf-sputtered molybdenum oxide films (1985)

Properties of rf-sputtered molybdenum oxide films for electrochromic display devices have been investigated. This report mainly concerns the dependence of the properties on the oxygen concentration in the sputtering atmosphere. The oxide films were prepared by rf sputtering from a compressed powder MoO3 target under an operating pressure of 4×10−2 Torr using a mixture of Ar-0.5–50% O2. Electrical resistivity of the films formed increases with increasing oxygen concentration in the sputtering atmosphere and ranges from 2.5×1010 to ∼1×1012 Ω cm. Spectral transmittance of the films is about 85% in the visible and near-infrared region. Optical band gap and refractive index of these films are 2.67–2.76 eV and 2.01–2.26, respectively. Electrochemichromic properties of the films were also studied using asymmetric cells, and it was found that a good electrochromic performance was obtained usually by the cells composed of the films with a resistivity of 2.5×1010 Ω cm.
Role of CCL2 (MCP-1) in Traumatic Brain Injury (TBI): Evidence from Severe TBI Patients and CCL2−/− Mice (2009)

Cerebral inflammation involves molecular cascades contributing to progressive damage after traumatic brain injury (TBI). The chemokine CC ligand-2 (CCL2) (formerly monocyte chemoattractant protein-1, MCP-1) is implicated in macrophage recruitment into damaged parenchyma after TBI. This study analyzed the presence of CCL2 in human TBI, and further investigated the role of CCL2 in physiological and cellular mechanisms of secondary brain damage after TBI. Sustained elevation of CCL2 was detected in the cerebrospinal fluid (CSF) of severe TBI patients for 10 days after trauma, and in cortical homogenates of C57Bl/6 mice, peaking at 4 to 12 h after closed head injury (CHI). Neurological outcome, lesion volume, macrophage/microglia infiltration, astrogliosis, and the cerebral cytokine network were thus examined in CCL2-deficient (-/-) mice subjected to CHI. We found that CCL2-/- mice showed altered production of multiple cytokines acutely (2 to 24 h); however, this did not affect lesion size or cell death within the first week after CHI. In contrast, by 2 and 4 weeks, a delayed reduction in lesion volume, macrophage accumulation, and astrogliosis were observed in the injured cortex and ipsilateral thalamus of CCL2-/- mice, corresponding to improved functional recovery as compared with wild-type mice after CHI. Our findings confirm the significant role of CCL2 in mediating post-traumatic secondary brain damage.
Interleaved angled MMI CWDM structure on the SOI platform (2013)

We have demonstrated a low-insertion-loss 8-channel interleaved angled MMI CWDM structure on the SOI platform. It requires only a single-step lithography and etching for fabrication and has good tolerance to fabrication errors.
Improving Facial Attribute Recognition by Group and Graph Learning (2021)

Exploiting the relationships between attributes is a key challenge for improving multiple facial attribute recognition. In this work, we are concerned with two types of correlations that are spatial and non-spatial relationships. For the spatial correlation, we aggregate attributes with spatial similarity into a part-based group and then introduce a Group Attention Learning to generate the group attention and the part-based group feature. On the other hand, to discover the non-spatial relationship, we model a group-based Graph Correlation Learning to explore affinities of predefined part-based groups. We utilize such affinity information to control the communication between all groups and then refine the learned group features. Overall, we propose a unified network called Multi-scale Group and Graph Network. It incorporates these two newly proposed learning strategies and produces coarse-to-fine graph-based group features for improving facial attribute recognition. Comprehensive experiments demonstrate that our approach outperforms the state-of-the-art methods.
Defect Chemistry and Transport within Dense BaCe<sub>0.7</sub>Zr<sub>0.1</sub>Y<sub>0.1</sub>Yb<sub>0.1</sub>O<sub>3 − δ</sub>(BCZYYb) Proton-Conducting Membranes (2018)

This paper uses previously published conductivity measurements as the basis for establishing thermodynamic and transport properties for BaCe0.7Zr0.1Y0.1Yb0.1O3 − δ (BCZYYb) proton-conducting membranes. BCZYYb is mixed ionic-electronic conducting (MIEC) doped perovskite that is dominantly a proton-conducting ceramic. In addition to protons, BCZYYb permits transport of oxygen vacancies and O-site polarons. The present analysis considers the effects of immobile polaron traps. The paper reports enthalpies ΔH° and entropies ΔS° for the defect reactions, and defect diffusion coefficients in Arrhenius form. The paper incorporates the thermodynamic and transport properties into a Nernst–Planck model to characterize BCZYYb performance as a protonic-ceramic membrane for electrolyzer and fuel-cell applications. Especially at temperatures below 600°C, BCZYYb can achieve high faradaic efficiencies (i.e., low electronic leakage) as an electrolyzer membrane.
Incorporating motion error in multi-frame structure from motion (2002)

Recovering structure from motion even using information from multiple image frames is difficult, in part because motion error can introduce large, correlated errors in the structure estimate. They propose a method for recursively recovering structure from motion that can deal with this problem. Encouraging results on real images and synthetic data are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Frequency offset compensation for crystal-free 802.15.4 communication (2011)

The IEEE 802.15.4 standard is widely used in low power wireless sensor networks. Providing 250kbps raw data band-width, its physical layer (PHY) mandates tight constraints on the RF carrier frequency, calling for an absolute accuracy of ±40 ppm. This specification necessitates the use of a crystal timing reference, thus requiring design of a multi-component PCB to implement any 802.15.4 compliant solution. However, in this work, a proposed frequency compensation algorithm can be added to the 802.15.4 PHY layer to relax the requirements on a timing reference to up to ±1000 ppm relative frequency error between a transmitter and receiver, allowing for the elimination of the crystal and paving the way for a single-chip integrated 802.15.4 wireless node. A wide bandwidth channel-select filter allows for offset in the received signal carrier frequency, while an additional demodulator output estimates that frequency offset. An adaptive feedback loop can then adjust the receiver clock rate to center the received signal in the channel, following which a narrowband filter can be applied to restore noise performance. Such a system has been simulated, and the results presented in this work demonstrate the feasibility of standards-compliant wireless communication using inaccurate timing references.
Isolation of mutants and genes involved in cytochromes c biosynthesis in Rhodobacter capsulatus (1989)

Mutants of the photosynthetic bacterium Rhodobacter capsulatus that have combined deficiencies in the cytochrome b/c1 complex and other c-type cytochromes have been isolated. These mutants were unable to grow anaerobically in the light or dark but could grow aerobically. Cosmids with R. capsulatus wild-type DNA that complement the mutants have been used to construct genetic and physical maps of the affected genes. Complementation profiles with Tn5 and mini-Mu insertions in these cosmids and subcloned fragments from them indicated that at least three genes (called helA, helB, and helC) are involved in the defects in cytochromes c biosynthesis. The genes are clustered, and helC is transcribed away from helA and helB. Stable insertion mutants in each gene were constructed. It is postulated that helA, helB, and helC are involved in posttranslational processing during cytochromes c synthesis.
In Situ XAS and XRD Studies on the Formation of Mo Suboxides during Reduction of MoO<sub>3</sub> (2000)

Reduction of MoO3 with hydrogen (5−100 vol %) in the temperature range from 573 to 823 K was studied by in situ X-ray diffraction and X-ray absorption spectroscopy. The experiments performed focused on elucidating phase composition and evolution with time under isothermal as well as temperature-programmed reduction conditions. At reaction temperatures below 698 K, the reduction of MoO3 to MoO2 is a one-step process without the formation of crystalline intermediates. At reduction temperatures above 723 K and H2 concentrations higher than 10 vol %, Mo metal is the final product of the reduction of MoO3. In addition, at temperatures higher than 698 K, the formation of Mo4O11 was observed. However, Mo4O11 is not an intermediate in the reduction of MoO3 but is being formed in a parallel reaction from MoO3 and MoO2 at temperatures above 698 K. It is shown that Mo4O11 can be obtained from a reaction of MoO3 and MoO2 at temperatures above 773 K, affording the same phase ratio of monoclinic and orthorhombic Mo4O11 as the reduction of MoO3 with hydrogen. Quantitative XRD analysis reveals a sigmoidal shape of the evolution of the MoO3 and MoO2 phases during reduction of MoO3 and an increase in the crystallite size of the phases present. This Oswald ripening indicates that a nucleation−growth kinetic mechanism governs the reduction of MoO3 under the conditions studied. The results presented in this work clearly demonstrate the potential of a combined application of in situ XRD and XAFS to reveal phase composition and kinetics of solid-state reactions.
Molecular cloning and expression of the regulatory (RG1) subunit of the glycogen-associated protein phosphatase (1991)

DNA clones encoding the glycogen-binding (RG1) subunit of glycogen-associated protein phosphatase were isolated from rabbit skeletal muscle lambda gt11 cDNA libraries. Overlapping clones provided an open reading frame of 3327 nucleotides that predicts a polypeptide of 1109 amino acids with a molecular weight of 124,257. Northern hybridization of rabbit RNA identified a major mRNA transcript of 7.5 kilobases present in skeletal, diaphragm, and cardiac muscle, but not in brain, kidney, liver, and lung. Southern analysis of rabbit genomic DNA digested with various restriction endonucleases gave rise to a single hybridizing fragment, suggesting that a single gene is present. Expression of the complete RG1 subunit coding sequence in Escherichia coli generated a protein of apparent molecular weight on sodium dodecyl sulfate-polyacrylamide gel electrophoresis of approximately 160,000, similar to the size of the polypeptide detected by Western immunoblot in rabbit skeletal muscle extracts. The RG1 subunit shares significant homology with the Saccharomyces cerevisiae GAC1 gene product which is involved in activation of glycogen synthase and glycogen accumulation. The homology with GAC1 substantiates the role of this enzyme in control of glycogen metabolism. Hydropathy analysis of the RG1 subunit amino acid sequence revealed the presence of a hydrophobic region in the COOH terminus, suggesting a potential association with membrane. This result suggests that the same phosphatase regulatory component may be involved in targeting the enzyme both to membranes and to glycogen.

Measurement of spin polarization by Andreev reflection in ferromagnetic In1−xMnxSb epilayers (2004)

We carried out point contact Andreev reflection (PCAR) spin spectroscopy measurements on epitaxially grown ferromagnetic In1−xMnxSb epilayers with a Curie temperature of ∼9 K. The spin sensitivity of PCAR in this material was demonstrated by parallel control studies on its nonmagnetic analog, In1−yBeySb. We found the conductance curves of the Sn point contacts with In1−yBeySb to be fairly conventional, with the possible presence of proximity-induced superconductivity effects at the lowest temperatures. These measurements provided control data for subsequent PCAR measurements on ferromagnetic In1−xMnxSb, which indicated spin polarization in In1−xMnxSb to be 52±3%.
Radiation Behavior of Vitreous Silica (1978)

Several properties of vitreous silica relevant to application as an optical element in a reactor were studied, including density, refractive index, optical path, stress relaxation, and optical absorption. The irradiations were in fields characteristic of the fuel regions of several operating reactors and at temperatures up to 370°C. The radiation-induced changes in optical path are significant, but are much smaller than those in the density and refractive index because the last two are of opposite sign. The thermal coefficient of optical path causes changes of comparable magnitude. Optical absorption is not a serious matter in the upper end of the visible region.
Conformer selection of protein ions by ion mobility in a triple quadrupole mass spectrometer (1994)

Electrospray mass spectra of multiply charged protein molecules show two distinct charge state distributions proposed to correspond to a more highly charged, open conformational form and a lower charged, folded form. Elastic collisions carried out in the radiofrequency-only collision cell of a triple quadrupole mass spectrometer have dramatic effects on the appearance of the mass spectra. The different cross sectional areas of the conformers allow preferential selection of one charge state distribution over the other on the basis of ion mobility. Preferential selection is dependent on the nature and pressure of the target gas as well as the nature of the protein. In the case of positively charged horse heart apomyoglobin (MW 16,951 da), a high charge state distribution centered around (M + 20H)(20+) predominates at low target gas pressures and a second distribution centered around (M + 10H)(10+) predominates at high target gas pressures. Bimodal distributions are observed at intermediate pressures and, remarkably, charge states between the two distributions are not effectively populated under most of the conditions examined. Hard sphere collision calculations show large differences in collision frequencies and in the corresponding kinetic energy losses for the two conformational states and they demonstrate that the observed charge state selectivity can be explained through elastic collisions.
