<title>Multifeature image and video content-based storage and retrieval</title> (1996)

In this paper we present most recent evolution of JACOB, a system we developed for image and video content-based storage and retrieval. The system is based on two separate archives: a 'features DB' and a 'raw-data DB'. When a user puts a query, a search is done in the 'features DB'; the selected items are taken form the 'raw-data DB' and shown to the user. Two kinds of sessions are allowed: 'database population' and 'database querying'. During a 'database population' session the user inserts new data into the archive. The input data can consist of digital images or videos. Videos are split into shots and for each shot one or more representative frames are automatically extracted. Shots and r-frames are then characterized, either in automatic or semi-automatic way, and stored in the archives. Automatic features' extraction consist of computing some low-level global features. Semi-automatic features' extraction is done by using annotation tools that perform operations that aren't currently possible with fully automatic methods. To this aim semi-automatic motion based segmentation and labeling tools have been developed. During a 'database querying' session, queries direct or by example are allowed. Queries may be iterated and variously combined to satisfy the query in the smallest number steps. Multifeature querying is based on statistical analysis of the feature space.
Characterization and Solubilization of Novel Aldosterone‐Binding Proteins in Porcine Liver Microsomes (1995)

Using the radioligand [1,2,6,7-3H]aldosterone ([3H]aldosterone), specific binding sites for aldosterone were identified and characterized in microsomal preparations from porcine liver. The maximum binding capacity is approximately 700 fmol x mg-1 microsomal protein. The reversible binding of [3H]aldosterone was saturable and Scatchard analysis revealed two apparent dissociation constants (Kd), Kd1 < or = 11 nM and Kd2 = 118 nM. Binding was optimal at pH 7.2, thermolabile, and was reduced by more than 70% when membrane vesicles were pretreated with trypsin. Binding was selective for aldosterone with cortisol being a weak agonist at 1000-fold higher concentrations only. Among those detergents tested to optimize conditions for solubilization, n-octylglucoside (75 mM) was most favorable and solubilized 25% of the radioligand-binding protein complex in the undissociated form. These binding sites have unique pharmacological properties, which are similar to those found for aldosterone membrane binding in human lymphocytes and pig kidney, and for rapid aldosterone effects on sodium-proton exchange.
Analysis of the third and fourth cell cycles of mouse early development (1986)

The third (4-cell) and fourth (8-cell) cell cycles of early mouse development have been analysed in populations of blastomeres synchronized to the preceding cleavage division. DNA content was measured microdensitometrically. The entry of blastomeres into these cell cycles showed considerable heterogeneity both within and between individual embryos. This heterogeneity was greater in the fourth than in the third cell cycle. The component phases of the third cell cycle were estimated as G1 = 1 h, S = 7 h, and G2 + M = 2-5 h, and those of the fourth cell cycle as G1 = 2 h, S = 7 h, and G2 + M = 1-3 h.
Effects of an organized critical care service on outcomes and resource utilization (1999)

Critical care interventions are expensive and have a narrow safety margin. It is essential to develop structured and validated approaches to study the delivery of this resource. In this study, the critical care service model performed favorably both in terms of quality and cost.
REFRACTIVE INDEX OF OPTICAL MATERIALS IN THE INFRARED REGION (1970)

Refractive index data and some extinction coefficients are provided for the infrared region for the following materials: silicon, germanium, zinc sulfide, cadmium telluride, zinc selenide, silica, calcium fluoride, magnesium fluoride, aluminum oxide, magnesium oxide, aluminum, gold and silver. The dependence of these optical constants on wavelength, temperature, crystal form, film preparation technique, radiation and other factors is included.
Self-Protecting Arrays for Open Drain Circuits (2006)

A new ESD protection strategy for NMOS arrays is described and experimentally evaluated. The problem of ESD protection of analog circuits has been addressed at the device/array level. Contrary to conventional rail-based or local clamp approaches this new concept provides for a self-protection capability into the array itself. The self-protecting capability of the NMOS array is achieved by embedding a local SCR region with reversible snapback capabilities and with a stronger dependence of the snapback voltage upon gate bias
How banks are authorised in the UK (2019)

In line with its financial stability and competition objectives the Bank of England has been, and will remain, supportive of firms wishing to become banks and enter the UK banking sector. The UK’s approach to authorising banks aims to strike an appropriate balance between ensuring robust control around the creation of new banks and not being so burdensome that it discourages suitably qualified firms from entering the market. Forty-six new banks have been authorised by the Prudential Regulation Authority (PRA) and the Financial Conduct Authority (FCA) since April 2013.

Optical clearing of unsectioned specimens for three-dimensional imaging via optical transmission and emission tomography (2008)

Optical computed tomography (optical-CT) and optical emission computed tomography (optical-ECT) are new techniques that enable unprecedented high-resolution 3-D multimodal imaging of tissue structure and function. Applications include imaging macroscopic gene expression and microvasculature structure in unsectioned biological specimens up to 8 cm(3). A key requisite for these imaging techniques is effective sample preparation including optical clearing, which enables light transport through the sample while preserving the signal (either light absorbing stain or fluorescent proteins) in representative form. We review recent developments in optical-CT and optical-ECT, and compatible "fluorescence-friendly" optical clearing protocols.
Chemosensitization of cultured human carcinoma cells to 1,3-bis(2-chloroethyl)-1-nitrosourea by difluoromethylornithine-induced polyamine depletion. (1985)

We have investigated the effect of pretreatment with the ornithine decarboxylase inhibitor alpha-difluoromethylornithine (DFMO) on the cytocidal efficacy of 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) in a series of five cultured human adenocarcinoma cell lines. Plating efficiency assays were used to generate BCNU dose-response survival curves for DFMO-treated and control cells. The cell lines varied in their sensitivity to BCNU, with A-427 (lung) and HuTu-80 (duodenum) cells being most sensitive, HT-29 (colon) and ME-180 (cervix) most resistant, and MCF-7 (breast) showing intermediate sensitivity. For all five cell lines, a 48-h pretreatment with 5 mM DFMO reduced intracellular putrescine and spermidine content to less than 10% of control levels and decreased spermine content to between 60 and 70% of controls. This pretreatment resulted in a shift of the BCNU survival curves for each of the five cell lines downward and to the left, indicating that the cells were sensitized to the lethal effects of BCNU. Dose enhancement ratios for DFMO-induced chemosensitization ranged from 1.2 (HuTu-80 cells at the 1% survival level) to 1.9 (HT-29 cells at the 10% survival level). The cell lines most resistant to BCNU appeared to give the greatest degree of potentiation by DFMO pretreatment. For four of the five cell lines, addition of 50 to 100 microM exogenous putrescine to DFMO-pretreated cultures 12 to 24 h before BCNU addition reversed the chemosensitization. ME-180 cells were the sole exception. Exogenous putrescine did not increase the surviving fraction after BCNU of any cells not pretreated with DFMO. These results suggest that DFMO-induced chemosensitization to BCNU in the four cell lines other than ME-180 is a specific consequence of the inhibition of ornithine decarboxylase by DFMO and the resulting depletion of intracellular polyamine content.
Colour and its changes in chillies. (1973)

In this review, attention is focussed on the complexity of chilli pigments and their storage stability. The following sections are included: pigments of chillies; isolation and purification of chilli pigments; colour measurement of chillies; colour degradation of chillies; and effect of various factors on the colour retention of chillies (moisture content, temp., light, fat content, antioxidants).
Novel devices in periodically poled lithium niobate (2003)

This thesis describes the research carried out to develop several novel periodically poled lithium niobate (PPLN) devices. These devices exploit the ability to invert micro-domains of spontaneous polarisation in ferroelectrics such as lithium niobate. \n\nThe fabrication of PPLN devices is described and extensive studies into factors influencing the poling quality are presented. In particular a comparison of material properties of unprocessed lithium niobate material from a range of different suppliers is carried out. Several novel PPLN devices are reviewed and two main devices are investigated - an electro-optically controlled Bragg grating modulator for laser beam switching and modulation and a titanium indiffused waveguide in PPLN for frequency conversion. \n\nThe design, fabrication and operation of the electro-optic Bragg modulators is described and results for the first infrared operation at 1064nm of such a device are presented. Several discrepancies are seen between experimental results, both in this thesis and previously published results, and a theoretical model based on Kogelnick?s coupled wave analysis. These anomalies are further investigated at visible operation (633nm and 488nm) and solutions and methods for alleviating the discrepancies are presented. \n\nWork on titanium indiffused channel waveguides in PPLN is reported, including a study into fabrication issues and the demonstration of second harmonic generation of 416nm in such a device.
Advanced software implementation of MPEG-4 AAC audio encoder (2004)

MPEG-4 AAC audio encoder is developed. AAC main and AAC low complexity object types, defined as part of main profile in general audio part of ISO/IEC 14496-3 (MPEG-4) standard, are implemented. Encoder targets high-quality, wideband, complex audio. Encoder was carefully designed to respect present accomplishments in audio coding (standardized in MPEG-4). At the same time, several implementation novelties were introduced. Encoder achieves 'perceptible but not annoying' 44.1 kHz audio quality at bit rate 64 kb/s/ch, while satisfying quality is accomplished at 48 kb/s/ch.

Vision-based Pose Estimation for Augmented Reality : A Comparison Study (2018)

Augmented reality aims to enrich our real world by inserting 3D virtual objects. In order to accomplish this goal, it is important that virtual elements are rendered and aligned in the real scene in an accurate and visually acceptable way. The solution of this problem can be related to a pose estimation and 3D camera localization. This paper presents a survey on different approaches of 3D pose estimation in augmented reality and gives classification of key-points-based techniques. The study given in this paper may help both developers and researchers in the field of augmented reality.
Ultraviolet matrix assisted laser desorption ionization‐mass spectrometry of electroblotted proteins (1996)

Direct mass spectrometric analysis of proteins electroblotted onto polyvinylidene fluoride membranes after sodium dodecyl sulfate-polyacrylamide gel electrophoresis is demonstrated by matrix-assisted laser desorption ionization-mass spectrometry (MALDI-MS) with a linear time-of-flight instrument, equipped with a nitrogen laser (337 nm). The blotted proteins were desorbed directly from the blotting membrane after incubation with sinapinic acid as matrix. Different commercially available membranes resulted in high quality protein signals for hydrophobic membranes exhibiting high specific surface areas (Immobilon PSQ or Trans-Blot) or for charged membranes (Immobilon CD). Systematic investigations with standard proteins were performed to compare standard preparation procedures for ultraviolet (UV) MALDI-MS on stainless steel sample stages and preparation of proteins immobilized onto membranes either by direct application from protein solutions (spotting) or by electrotransfer from gels (electroblotting). Aspects such as mass resolution reproducibility from shot to shot and spot to spot, mass accuracy, and preservation of protein localization are addressed in this paper.

Chemical Attractants for AdultDrosophilaSpecies1 (1961)

The development of chemical attractants as baits for Drosophila species is described. A large series of compounds was first tested by means of vial traps in closed containers. The more promising compounds and mixtures were tested by exposure in bottle traps in a closed room. These room tests demonstrated that mixtures were more effective than any one compound. A selection of the Lest compounds and mixtures was given field tests in a humid region with abundant vegetation. The most effective mixture found consisted of malt extract 5%, ethyl alcohol 0.5%, skatole 0.02% and acetal 1%. In field trials, 380 cc. of the attractant solution was mixed with 240 grams of finely ground peat and 40 grams of alfalfa meal to form a paste.
Molecular pathogenesis of oral submucous fibrosis – a collagen metabolic disorder (2005)

Oral submucous fibrosis (OSF) is a chronic debilitating disease and a premalignant condition of the oral cavity. It is characterized by a generalized submucosal fibrosis. The pathogenesis of the disease is not well established. Epidemiological evidences strongly indicate the association of the betel quid (BQ) habit and OSF. Various findings indicate the disease to be a consequence of disturbances in the homeostatic equilibrium between synthesis and degradation of extracellular matrix (ECM), wherein collagen forms a major component, thus can be considered as a collagen-metabolic disorder. Transforming growth factor-beta (TGF-beta) is a potent stimulator of production and deposition of the ECM. The objectives of this review are to highlight the molecular events involved in the overproduction of insoluble collagen and decreased degradation of collagen occurring via exposure to BQ and stimulation of the TGF-beta pathway, and elucidate the cell signaling that is involved in the etiopathogenesis of the disease process.
Does heart rate variability reflect the systemic inflammatory response in a fetal sheep model of lipopolysaccharide-induced sepsis? (2015)

Fetal inflammatory response occurs during chorioamnionitis, a frequent and often subclinical inflammation associated with increased risk for brain injury and life-lasting neurologic deficits. No means of early detection exist. We hypothesized that systemic fetal inflammation without septic shock will be reflected in alterations of fetal heart rate (FHR) variability (fHRV) distinguishing baseline versus inflammatory response states. In chronically instrumented near-term fetal sheep (n = 24), we induced an inflammatory response with lipopolysaccharide (LPS) injected intravenously (n = 14). Ten additional fetuses served as controls. We measured fetal plasma inflammatory cytokine IL-6 at baseline, 1, 3, 6, 24 and 48 h. 44 fHRV measures were determined continuously every 5 min using continuous individualized multi-organ variability analysis (CIMVA). CIMVA creates an fHRV measures matrix across five signal-analytical domains, thus describing complementary properties of fHRV. Using principal component analysis (PCA), a widely used technique for dimensionality reduction, we derived and quantitatively compared the CIMVA fHRV PCA signatures of inflammatory response in LPS and control groups. In the LPS group, IL-6 peaked at 3 h. In parallel, PCA-derived fHRV composite measures revealed a significant difference between LPS and control group at different time points. For the LPS group, a sharp increase compared to baseline levels was observed between 3 h and 6 h, and then abating to baseline levels, thus tracking closely the IL-6 inflammatory profile. This pattern was not observed in the control group. We also show that a preselection of fHRV measures prior to the PCA can potentially increase the difference between LPS and control groups, as early as 1 h post LPS injection. We propose a fHRV composite measure that correlates well with levels of inflammation and tracks well its temporal profile. Our results highlight the potential role of HRV to study and monitor the inflammatory response non-invasively over time.
Preparation and Properties of Polyallenes. II. Phase Transitions of Polyallene (1968)

Abstract Polyallenes prepared with the aid of organoaluminum-VOCl3 catalysts appear to exist in three distinct phases: two crystalline phases (I and II) and an amorphous phase. Phase I shows two strong X-ray diffraction peaks at d = 5.62 Å and d = 4.04 Å; phase II has three strong peaks at d = 6.28 Å, d = 5.03 Å, and d = 4.21 Å. The band of the amorphous phase has its maximum at about d = 5.6 Å.
A Closed-Loop Mechanical Ventilation Controller With Explicit Objective Functions (2004)

A closed-loop lung ventilation controller was designed, aiming to: 1) track a desired end-tidal CO2 pressure (Pet CO2), 2) find the positive end-expiratory pressure (PEEP) of minimum estimated respiratory system elastance (Ers,e), and 3) follow objective functions conjectured to reduce lung injury. After numerical simulations, tests were performed in six paralyzed piglets. Respiratory mechanics parameters were estimated by the recursive least squares (RLS) method. The controller incorporated a modified PI controller for Pet CO2 and a gradient descent method for PEEP. In each animal, three automated PEEP control runs were performed, as well as a manual PEEP titration of Ers,e and a multiple PetCO2 step change trial. Overall performance indexes were obtained from PEEP control, such as minimum Ers,e (37.0 +/- 4.5 cmH2O x L(-1)), time to reach the minimum Ers,e (235 +/- 182 s) and associated PEEP (6.5 +/- 1.0 cmH2O), and from Pet CO2 control, such as rise time (53 +/- 22 s), absolute overshoot/undershoot of PetCO2 (3 +/- 1 mmHg), and settling time (145 +/- 72 s). The resulting CO2 controller dynamics approximate physiological responses, and results from PEEP control were similar to those obtained by manual titration. Multiple dependencies linking the involved variables are discussed. The present controller can help to implement and evaluate objective functions that meet clinical goals.
Toll‐like receptor and tumour necrosis factor dependent endotoxin‐induced acute lung injury (2007)

Recent studies on endotoxin/lipopolysaccharide (LPS)-induced acute inflammatory response in the lung are reviewed. The acute airway inflammatory response to inhaled endotoxin is mediated through Toll-like receptor 4 (TLR4) and CD14 signalling as mice deficient for TLR4 or CD14 are unresponsive to endotoxin. Acute bronchoconstriction, tumour necrosis factor (TNF), interleukin (IL)-12 and keratinocyte-derived chemokine (KC) production, protein leak and neutrophil recruitment in the lung are abrogated in mice deficient for the adaptor molecules myeloid differentiation factor 88 (MyD88) and Toll/Interleukin-1 receptor (TIR)-domain-containing adaptor protein (TIRAP), but independent of TIR-domain-containing adaptor-inducing interferon-beta (TRIF). In particular, LPS-induced TNF is required for bronchoconstriction, but dispensable for inflammatory cell recruitment. Lipopolysaccharide induces activation of the p38 mitogen-activated protein kinase (MAPK). Inhibition of pulmonary MAPK activity abrogates LPS-induced TNF production, bronchoconstriction, neutrophil recruitment into the lungs and broncho-alveolar space. In conclusion, TLR4-mediated, bronchoconstriction and acute inflammatory lung pathology to inhaled endotoxin are dependent on TLR4/CD14/MD2 expression using the adapter proteins TIRAP and MyD88, while TRIF, IL-1R1 or IL-18R signalling pathways are dispensable. Further downstream in this axis of signalling, TNF blockade reduces only acute bronchoconstriction, while MAPK inhibition abrogates completely endotoxin-induced inflammation.
A randomized double-blind controlled study of 6 months of oral nutritional supplementation with arginine and Ω-3 fatty acids in HIV-infected patients (1998)

Enrichment of an oral nutritive supplement with arginine and omega-3 fatty acids did not improve immunological parameters. However, body weight increased in both groups.
