The role of the ion-solid interaction in ion-beam-induced deposition of gold (1991)

Gold films were deposited on quartz-crystal microbalances by decomposing C7H7F6O2Au (dimethyl gold hexafluoroacetylacetonate) with 2–10-keV Xe+, Kr+, Ar+, Ne+, or He+ ion beams. The number of molecules decomposed per incident ion (i.e., the total decomposition yield) was determined as a function of ion mass and energy. The total decomposition yield increases with increasing ion mass and ion energy, and is approximately proportional to the nuclear stopping power. A binary collision model and a thermal spike model are developed that relate the energy deposited by the ion, at the substrate surface, to the total number of molecules decomposed. Both models predict total decomposition yields that are in reasonable agreement with the experimental measurements; however, the variation of total yield with changes in ion mass and energy are best described by the binary collision model. The success of both models demonstrates that the energy deposited into the substrate surface through the ion-solid interaction is responsible for the decomposition of adsorbed molecules.
Detection of Chromosome 11q13 Breakpoints by Interphase Fluorescence In Situ Hybridization (2000)

We assessed cytologic specimens from 11 mantle cell lymphomas (MCLs) and 32 other B-cell non-Hodgkin lymphomas (NHLs) for 11q13 breakpoints using a 2-color fluorescence in situ hybridization (FISH) assay that uses an 11q13 probe centered on the CCND1 gene and a centromeric chromosome 11 probe (CEP11). The number of nuclei in 200 cells were counted, and results were expressed as an 11q13/CEP11 ratio. All MCLs showed a high percentage of interphase nuclei with 3 or more 11q13 signals (mean, 74.8%; range 57%-90%). In contrast, in other B-cell NHLs the mean percentage of cells with 3 or more 11q13 signals was 9.2%. All MCLs had an elevated 11q13/CEP11 ratio (mean, 1.38). The mean ratio for other B-cell NHLs was 0.99. Two non-MCL cases, 1 large B-cell and 1 B-cell unclassified NHL, had high 11q13/CEP11 ratios of 1.15 and 1.30, respectively. Conventional cytogenetic analysis performed on the former case revealed a t(5;11)(q31;q13). Interphase FISH analysis using 11q13 and CEP11 probes is a convenient ancillary method for assisting in the diagnosis of MCL. This commercially available assay is simple to use on cytology or imprint specimens, and results can be obtained within 24 hours.
Studies on the chemical constituents of rutaceous plants. LX. Development of a versatile method for syntheses of the antitumor benzo(c)phenanthridine alkaloids. 9. Efficient syntheses and antitumor activities of nitidine and related nonphenolic benzo(c)phenanthridine alkaloids. (1985)

Several nonphenolic benzo [c] phenanthridine alkaloids including naturally occurring nitidine (1a) and avicine (1e) were synthesized in excellent yields through an efficient synthetic method developed by us. Antitumor activities of twelve alkaloids including four naturally occurring O5-alkaloids [chelilutine (1g), chelirubine (1h), sanguilutine (1k), and sanguirubine (11)] against Sarcoma 180 were tested. The structure-activity relationship of these alkaloids is discussed.
Observations of movement dynamics of flying insects using high resolution lidar (2016)

Insects are fundamental to ecosystem functioning and biodiversity, yet the study of insect movement, dispersal and activity patterns remains a challenge. Here we present results from a novel high resolution laser-radar (lidar) system for quantifying flying insect abundance recorded during one summer night in Sweden. We compare lidar recordings with data from a light trap deployed alongside the lidar. A total of 22808 insect were recorded, and the relative temporal quantities measured matched the quantities recorded with the light trap within a radius of 5 m. Lidar records showed that small insects (wing size <2.5 mm(2) in cross-section) moved across the field and clustered near the light trap around 22:00 local time, while larger insects (wing size >2.5 mm(2) in cross-section) were most abundant near the lidar beam before 22:00 and then moved towards the light trap between 22:00 and 23:30. We could distinguish three insect clusters based on morphology and found that two contained insects predominantly recorded above the field in the evening, whereas the third was formed by insects near the forest at around 21:30. Together our results demonstrate the capability of lidar for distinguishing different types of insect during flight and quantifying their movements.
Phosphatase production byAspergillus ficuum (1987)

Effects of nutritional and cultural conditions on cell growth and phosphatase production byAspergillus ficuum were studied.A. ficuum produced high levels of phosphatases when grown on a basal medium that contained a minimal amount (2 mg/100 ml) of phosphorus in an acidic growth medium. The organism produced a nonspecific acid phosphomonoesterase rather than phytin-specific phosphatase. The enzyme hydrolyzed a variety of phosphates and produced orthophosphate. The rate of phosphate hydrolysis was dependent on the pH of the reaction, where the pH optimum for acid phosphatase was 2.5 and that for phytase was 5.0. The organism slowly released the phosphatase, and the enzyme activity in the growth medium increased continually during a one-month growth period. For a high level of phosphatase production, low levels (1–5 mg%) of initial phosphorus were necessary and polyphosphates were the desired form rather than the monophosphate. The addition of surfactants, such as polyoxyethylene ethers and sodium oleate, to fungal culture medium markedly increased the level of phosphatase production.
A chip set for lossless image compression (1991)

The authors describe two chips which form the basis of a high-speed lossless image compression/decompression system. They present the transform and coding algorithms and the main architectural features of the chips and outline some performance specifications. Lossless compression can be achieved by a transformation process followed by entropy coding. The two application-specific integrated circuits (ASICs) perform S-transform image decomposition and the Lempel-Ziv (L-Z) type of entropy coding. The S-transform, besides decorrelating the image, provides a convenient method of hierarchical image decomposition. The data compressor/decompressor IC is a fast and efficient implementation of the L-Z algorithm. The chips can be used independently or together for image compression.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Edge computing architectures (2020)

By considering an edge computing platform as one of the main computing tiers in a fully comprehensive cloudisation model, this chapter first discusses the distinguished features of edge computing compared to other platforms from the perspectives of service, operation and control. In addition, a local view of the intrinsic architecture of an edge computing host is analysed. Subsequently, a standard reference architecture of the edge computing platform is presented, which defines the internal and external interfaces among components at the computing host and system levels. The reference architecture is matched to the network function virtualisation management and orchestration (NFV MANO) model for consideration as a virtualised network function (VNF). In particular, the position and roles of VNF edge computing in the standard mobile network reference model are demonstrated. Finally, the open issues and challenges are presented by way of conclusion.
Loss of emotional experience after traumatic brain injury: Findings with the startle probe procedure. (2006)

The authors used affective modulation of the eyeblink startle response to examine the impact of traumatic brain injury (TBI) on emotional reactions to pictures. Participants were 13 individuals with severe TBI and 24 controls. Participants were presented with pictures that differed in affective valence (e.g., mutilated bodies, erotic couples, and household objects) while the eyeblink startle response to an acoustic probe was measured. Startle amplitude was used to assess valence of emotional response, and startle latency was used to index interest in the pictures. Subjective ratings of the affect and arousal elicited by the various pictures were also obtained. TBI impaired startle potentiation to unpleasant pictures but not startle attenuation to pleasant pictures. Further, subjective ratings indicated that TBI participants found unpleasant pictures less arousing than did controls. The results are consistent with recent evidence of differential impairment in negative versus positive emotions after TBI and are discussed in relation to 2 competing explanations of startle modulation.
Slow Photoelectron Velocity-Map Imaging of the <i>i</i>-Methylvinoxide Anion (2010)

High-resolution photoelectron spectra of the i-methylvinoxide anion are obtained by slow electron velocity-map imaging. The transitions between the anion ground electronic state, X̃ (1)A', and the radical X̃ (2)A'', and Ã (2)A' states are measured. Franck-Condon simulations of the X̃ (2)A'' ← X̃ (1)A' transition are performed to aid in assigning peaks, yielding several vibrational frequencies for the first time. Additional structure in the spectrum of the X̃ (2)A'' ← X̃ (1)A' transition is attributed to hindered rotor motion of the methyl group. Simulation of methyl torsional states allows identification of the true origin peak, yielding the experimental adiabatic electron affinity, EA = 1.747 ± 0.002 eV, and the Ã state term energy, T(0) = 1.037 ± 0.002 eV. Comparison with the fully deuterated isotopologue further supports the assignment of hindered rotor progressions. The favored methyl rotor position is eclipsed in the radical X̃ state and staggered in the anion X̃ and radical Ã states.
Clinical spectrum of ear, nose and throat foreign bodies in North Western Nigeria (2016)

Ear, nose and throat foreign bodies are common in North-Western Nigeria with the highest incidence in children. Removal attempts by untrained health professionals and lack of experience in FB management predisposes to complications. Parental education on close monitoring of their children to avoid such incidences and the need to immediately seek an Otorhinolaryngologist to prevent complications are emphasized.
Circadian Body Temperatures and the Effects of a Cold Stress in Elderly and Young Subjects (1995)

To determine whether there is a decrement in normal resting body temperature with age, 11 healthy elderly and 11 young adults were studied together for 48 h in warm (21 degrees C) ambient conditions. The resting levels and daytime rhythms of urine and oral temperature were similar, but night-time body temperature fell to a lower value in the young. There were time-of-day effects of increasing skin temperature and metabolic rate in both groups with resting levels higher in the young. After 6 h in cold (6 degrees C) conditions, core (urine) temperature fell by 0.4 degrees C in the elderly subjects but was maintained in the young, and the rise in blood pressure in the elderly exceeded that in the young. Self-reported arousal, however, increased equally in both groups in the cold.
Ear Recognition by means of a Rotation Invariant Descriptor (2006)

Iannarelli's studies showed that ear shape can be considered a biometric identifier able to authenticate people as well as more established biometrics like face or voice, for instance. However, very few researches can be found in literature about ear recognition. In most cases techniques already working in other biometric fields, such as PCA (principal component analysis), are applied to ear. Eigen-ears provide high recognition rate only in closely controlled conditions. Indeed, even a slight amount of rotation can cause a significant drop in system performance and in unattended systems rotations occur very frequently. In this paper, we propose the use of a rotation invariant descriptor, namely GFD (generic Fourier descriptor), to extract meaningful features from ear images. This descriptor results to be quite robust to both ear rotations and illumination changes. Experimental results confirm the superiority of this approach even compared to Eigen-ears
Measurement of Spectral Bandwidth, as Exemplified with the Beckman "Enzyme Analyzer System TR Spectrophotometer" (1975)

This paper describes simple methods for determining spectral bandwidth by measurement and by calculation. We measured the spectral bandwidth of the monochromator from the Beckman Enzyme Analyzer TR, and found it to be 3.5-4.0 nm (av 3.8) by two different methods. We visually estimated it to be 4 nm. Using the specifications for the diffraction grafting, focal length, and fixed slit width, we calculated the theoretical spectral bandwidth to be 3.6 nm.
Candidiasis in Malignancy (2006)

Esophageal candidiasis presents with a range of clinical findings and is rarely found among immunocompetent patient without predisposing factors. Between 20-50% of patient may be asymptomatic. One of predisposing factor of candidiasis is immunocompromised condition due to malignancy. Dysphagia is the most frequently presented feature of esophageal carcinoma. We demonstrated a case of esophageal candidiasis as one of early clinical presentation in patient with esophageal carcinoma. Keywords : esophageal candidiasis, esophageal carcinoma
An Interactive Environment for Data Partitioning and Distribution (2005)

An a.pproach to distributed riieiiiory pa.ralle1 programining that has recently become popular is oue where the programmer explicitly specilies t.he data decoiriposit.ionusing language extensions, and a. compiler geuerates all the coiriinunicatioii.While this frees the prograiniuer froin tlie tedium of thinking about message-passing, no assistance is provided in determining the data decouiposition scheme that gives the best performance on tlie target machine.In this paper, we propose an interactive software tool that provides assistance for this very task.The proposed tool also computes performance estimates for any chosen data partitioning scheme, allowing tlie programmer to experiment with several different stra.tegieswithout ever running the program on the rnacliine.Although distributed memory parallel computers are among the most cost-effective machines available, most scientists find them difficult to program.The reason is that traditional programming languages support shared name spaces and, as a result, most p r e grainiiiers feel more comfortable working with a shared inemory programming model.To this end, a nuiiiber of researchers [6,16, 4,19,15,12, 51 have proposed using a traditional sequential or shared-iiiemory language extended with annotations specifying how the data is to be distributed.This approach is inspired by tlie observation that (lie most deriianding intellectual step in programming for distributed memory is the data layout -the rest is straightforward but tedious and error prone work.Given a program and annotations of this sort, a compiler can mechanically generate the node program for a distributed-irieniory machine.This strategy is illustrated by steps I1 and I11 in Figure 1.A problem with this approach is that it provides no
The effect of truncation on very small cardiac SPECT camerasystems (2006)

Background: The limited transaxial field-of-view (FOV) of avery small cardiac SPECT camera system causes view-dependent truncationof the projection of structures exterior to, but near the heart. Basictomographic principles suggest that the reconstruction of non-attenuatedtruncated data gives a distortion-free image in the interior of thetruncated region, but the DC term of the Fourier spectrum of thereconstructed image is incorrect, meaning that the intensity scale of thereconstruction is inaccurate. The purpose of this study was tocharacterize the reconstructed image artifacts from truncated data, andto quantify their effects on the measurement of tracer uptake in themyocardial. Particular attention was given to instances where the heartwall is close to hot structures (structures of high activity uptake).Methods: The MCAT phantom was used to simulate a 2D slice of the heartregion. Truncated and non-truncated projections were formed both with andwithout attenuation. The reconstructions were analyzed for artifacts inthe myocardium caused by truncation, and for the effect that attenuationhas relative to increasing those artifacts. Results: The inaccuracy dueto truncation is primarily caused by an incorrect DC component. Forvisualizing theleft ventricular wall, this error is not worse than theeffect of attenuation. The addition of a small hot bowel-like structurenear the left ventricle causes few changes in counts on the wall. Largerartifacts due to the truncation are located at the boundary of thetruncation and can be eliminated by sinogram interpolation. Finally,algebraic reconstruction methods are shown to give better reconstructionresults than an analytical filtered back-projection reconstructionalgorithm. Conclusion: Small inaccuracies in reconstructed images fromsmall FOV camera systems should have little effect on clinicalinterpretation. However, changes in the degree of inaccuracy in countsfrom slice toslice are due to changes in the truncated structures. Thesecan result in a visual 3-dimensional distortion. As with conventionallarge FOV systems attenuation effects have a much more significant effecton image accuracy.
The effect of cochliodinol, a metabolite of <i>Chaetomium cochliodes</i>, on the respiration of microspores of <i>Fusarium oxysporum</i> (1971)

Cochliodinol at 15 μg/ml reduced the respiration rate of microspores of Fusarium oxysporum, with glucose or succinate as substrate, by about 70%, and also inhibited their germination. The inhibitory effect was partially reversed by the addition of magnesium ions to the medium.
Antibacterial Galloylated Alkylphloroglucinol Glucosides from Myrtle (<i>Myrtus </i><i>c</i><i>ommunis</i>) (2006)

An investigation of the polar glycosidic fraction from the leaves of myrtle afforded four galloylated nonprenylated phloroglucinol glucosides (3a-d) related to the endoperoxide hormone G3 (4) in terms of structure and biogenesis. Despite their close similarity, significant antibacterial activity was shown only by one of these compounds (3b, gallomyrtucommulone B), while the G3 hormone (4) was inactive.

Emergence of tetracycline-resistant Vibrio cholerae O1 serotype Inaba, in Kolkata, India. (2008)

Out of 2,235 diarrheal stool samples collected from patients admitted to the Infectious Diseases Hospital, Kolkata, 343 cases were positive for Vibrio cholerae (341, V. cholerae O1 and 2, O139). During the year 2004, infections caused by V. cholerae serotype Ogawa and Inaba were 93 and 7%, respectively, while in 2005, the Inaba isolation rate rose to 88% as compared to 12% for Ogawa. Susceptibility to antimicrobial agents revealed that the O1 strains were resistant to multiple antibiotics (ampicillin, co-trimoxazole, furazolidone, nalidixic acid and streptomycin) with reduced susceptibility to ciprofloxacin. Increased isolation of tetracycline-resistant strains (27.3% for Ogawa and 15% for Inaba) was noted in 2005. It appears that the population might be at risk of infection by the Inaba serotype and that tetracycline may not be useful for the treatment.
Group-based Coordinated Checkpointing for MPI: A Case Study on InfiniBand (2007)

As more and more clusters with thousands of nodes are being deployed for high performance computing (HPC), fault tolerance in cluster environments has become a critical requirement. Checkpointing and rollback recovery is a common approach to achieve fault tolerance. Although widely adopted in practice, coordinated checkpointing has a known limitation on scalability. Severe contention for bandwidth to storage system can occur as a large number of processes take a checkpoint at the same time, resulting in an extremely long checkpointing delay for large parallel applications. In this paper, we propose a novel group-based checkpointing design to alleviate this scalability limitation. By carefully scheduling the MPI processes to take checkpoints in smaller groups, our design reduces the number of processes simultaneously taking checkpoints, while allowing those processes not taking checkpoints to proceed with computation. We implement our design and carry out a detailed evaluation with micro-benchmarks, HPL, and the parallel version of a data mining toolkit, MotifMiner. Experimental results show our group-based checkpointing design can reduce the effective delay for checkpointing significantly, up to 78% for HPL and up to 70% for MotifMiner.
In vitro digestibility of the testa in tannin-free field beans (<i>Vicia faba</i> L.) (1976)

Summary The seed-coat of all white-flowered varieties of Vicia faba and segregants tested was free of tannin. In two field trials, the whole grain of white-flowered varieties wassignificantly higher in in vitro digestibility of the dry matter, on average 4·7% higher, than coloured-flowered varieties of similar seed size. In subsequent trials where the testa and cotyledon were examined separately, this difference was shown to be largely due to a mean D value (digestibility of the organic matter) of the testa in tannin-free varieties of 56·4% compared with 17·2% in tannin-containing varieties. Seed size was positively correlated with D value but not because of differing proportions of testa. Differences between varieties in acid-pepsin solubility and protein content of the testa were much smaller and not associated with presence of tannin. The testa colour of some tannin-free F 2 plants was a darker shade of grey than either parental population. An inbred line completely lacking in anthocyanin in flowers and stem but with the normal black wing spot had tannin in its testa. Grains of peas from the coloured-flowered variety, Minerva, reacted to a tannin test wheieas those from white-flowered varieties, Greenshaft and Flavanda, did not. The case for breeding further tannin-free varieties of Vicia faba is discussed.
