Dominant object detection for autonomous vision-based surveillance (2010)

The deployment of visual surveillance and monitoring systems has reached massive proportions. Consequently, a need to automate the processes involved in retrieving useful information from surveillance videos, such as detecting and counting objects, and interpreting their individual and joint behavior, has emerged. The existing methods targeting such automation and working towards "smart" surveillance solutions largely rely on pattern recognition solutions trained offline in a supervised fashion. In this thesis we address the challenge of minimizing the level of supervision in automating the smart surveillance mechanisms. In particular, we focus on the development of fully autonomous detectors of objects that are typical for the observed scene. Using such solutions, objects can be observed and counted (e.g. pedestrians in a shopping street, cars and trucks on a highway), but also atypical objects can be detected leading to automatic security alerts. The rationale behind our proposed solution is that the characteristics of a scene or objects involved can be learned if sufficient time for observation is given, and if the measured features characterizing the properties of the scene and objects are generic enough. In the first step, we demonstrate how candidates for the typical objects can be separated from the scene background using an existing robust motion segmentation mechanism and our novel shadow removal method. In the second step, the set of candidate objects is filtered using an automatically learned perspective deformation model to remove irrelevant objects and compensate for the imperfections of the motion segmentation and shadow removal processes. Finally, in the third step, a module is developed, in which the candidate typical objects are used as positive training samples to train an advanced typical object detector. The effectiveness of this three-step approach is demonstrated first on the case of a single typical object class present in the observed scene. Then, we also show how the proposed approach can be expanded to simultaneously detect two such object classes, if present.

Semiconducting Polymer Photodetectors with Electron and Hole Blocking Layers: High Detectivity in the Near-Infrared (2010)

Sensing from the ultraviolet-visible to the infrared is critical for a variety of industrial and scientific applications. Photodetectors with broad spectral response, from 300 nm to 1,100 nm, were fabricated using a narrow-band gap semiconducting polymer blended with a fullerene derivative. By using both an electron-blocking layer and a hole-blocking layer, the polymer photodetectors, operating at room temperature, exhibited calculated detectivities greater than 10(13) cm Hz(1/2)/W over entire spectral range with linear dynamic range approximately 130 dB. The performance is comparable to or even better than Si photodetectors.

Subcellular organization of UBE3A in neurons (2016)

ABSTRACT Ubiquitination regulates a broad array of cellular processes, and defective ubiquitination is implicated in several neurological disorders. Loss of the E3 ubiquitin–protein ligase UBE3A causes Angelman syndrome. Despite its clinical importance, the normal role of UBE3A in neurons is still unclear. As a step toward deciphering its possible functions, we performed high‐resolution light and electron microscopic immunocytochemistry. We report a broad distribution of UBE3A in neurons, highlighted by concentrations in axon terminals and euchromatin‐rich nuclear domains. Our findings suggest that UBE3A may act locally to regulate individual synapses while also mediating global, neuronwide influences through the regulation of gene transcription. J. Comp.

Spontaneous Colorimetric Sensing of the Positional Isomers of Dihydroxynaphthalene in a 1D Organogel Matrix (2006)

Like a color palette: A naphthalenediimide-based organogel colorimetric sensor allows recognition of the positional isomers of dihydroxynaphthalene in the gel phase with the naked eye. Intercalation of the dihydroxynaphthalene into the gel matrix produces a donor–acceptor interaction, which gives the gel a distinct color that depends on the strength of noncovalent (H-bonding, π-stacking, van der Waals) interactions.

Some Characteristics of Steroid Diabetes: A Study in Renal-Transplant Recipients Receiving High-Dose Corticosteroid Therapy (1983)

Risk factors and course of steroid diabetes were investigated in 145 renal-transplant recipients who were given a high-dose steroid regimen. Persistent steroid diabetes developed in 25% of the patients and transient diabetes in another 22%. When antidiabetic therapy was required, insulin had to be given in 50%. The incidence of steroid diabetes correlated with steroid dose, age, body weight, and diabetes heredity but not with abnormal glucose tolerance or with another complication of steroid therapy, posterior-pole lenticular cataract. There was no association with HLA-A and B antigens. Thus, steroid diabetes is a frequent complication of high-dose corticosteroid therapy and is similar to type II diabetes. However, it often requires insulin therapy.

EV-D68 may be one of the causative agents for AFM, while host susceptibility factors such as immune response could contribute to AFM development.
A proposed structure of a 4 Mbit content-addressable and sorting memory (1990)

A new structure for a high-density 4-Mb CAM (content addressable memory) with sorting function (sort-CAM) is proposed. Retrieval or sorting operations are done in word-parallel/bit-serial manner at the device. This is different from previous CAMs where operations are done in word-parallel/bit-parallel or flash manner. The device organization, circuits for retrieval or sorting, and chip operations are explained. Estimated performance of the device and chip size are also discussed. The device has 64 K-word×64-b organization and a 3.1-MB/s sorting speed. In practical applications, such as RDB (relational database) systems, this speed is enough, but a number of chips should be connected if larger data volume is needed
Identification of Epitopes and Affinity Purification of Thyroid Stimulating Auto-Antibodies using Synthetic Human Tsh Receptor Peptides (1994)

We prepared a series of overlapping peptides (29 in total, 20 amino acids each) containing the sequence of the entire extracellular domain of the human TSH receptor. Three peptides (181-200, 376-394, and EC3 (629-639)) bound IgG from patients with Graves' disease in an enzyme linked immunoassay. Peptide 181-200 bound IgG from 9 of 10, EC3 from 8 of 10, and 376-394 from 6 of 10 patients respectively, compared to 0 of 9 controls. We affinity purified TSHr auto-antibodies from four Graves' patients using the three above noted peptides bound to epoxy-activated sepharose. Thyroid stimulating activity was enriched in the bound fraction from at least two of the three peptide affinity columns in each of the four patients, although the pattern of affinity enrichment differed between patients. One patient was found to possess a combination of stimulatory and inhibitory TSHr antibodies and, after affinity purification, the anti-376-394 and anti-EC3 fractions were enriched in stimulatory activity, suggesting that those regions of the receptor were epitopes for stimulatory antibodies. However, affinity purification against peptide 181-200 produced an IgG preparation that was not stimulatory, but was a potent thyroid inhibitor. Thus, we have not only partially purified TSHr auto-antibodies, but also successfully separated stimulatory and inhibitory antibodies from a single patient using combination TSHr peptide affinity.
Habitual snoring with and without obstructive sleep apnoea: the importance of cephalometric variables. (1992)

The lack of association between cephalometric variables and mild sleep apnoea suggests that the differences in these variables (soft tissue measures) may be the consequence rather than the cause of habitual snoring and the obstructive sleep apnoea syndrome.
ZnO‐Based Transparent Conductive Thin Films: Doping, Performance, and Processing (2013)

ZnO‐based transparent conductive thin films have attracted much attention as a promising substitute material to the currently used indium‐tin‐oxide thin films in transparent electrode applications. However, the detailed function of the dopants, acting on the electrical and optical properties of ZnO‐based transparent conductive thin films, is not clear yet, which has limited the development and practical applications of ZnO transparent conductive thin films. Growth conditions such as substrate type, growth temperature, and ambient atmosphere all play important roles in structural, electrical, and optical properties of films. This paper takes a panoramic view on properties of ZnO thin films and reviews the very recent works on new, efficient, low‐temperature, and high‐speed deposition technologies. In addition, we highlighted the methods of producing ZnO‐based transparent conductive film on flexible substrate, one of the most promising and rapidly emerging research areas. As optimum‐processing‐parameter conditions are being obtained and their influencing mechanism is becoming clear, we can see that there will be a promising future for ZnO‐based transparent conductive films.
Involvement of histamine H<sub>4</sub> and H<sub>1</sub> receptors in scratching induced by histamine receptor agonists in BalbC mice (2004)

The role of histamine H(1), H(2), H(3) and H(4) receptors in acute itch induced by histamine was investigated in female BalbC mice. Scratching was induced by intradermal injections of pruritogen into the back of the neck and "itch" assessed by quantifying the scratching evoked. Histamine (0.03-80 micromol), histamine-trifluoromethyl-toluidine (HTMT, H(1) agonist, 0.002-2 micromol), clobenpropit (H(4) agonist, H(3) antagonist, 0.002-0.6 micromol) and to a lesser extent imetit (H(3)/H(4) agonist, 0.03-3 micromol) all induced dose-dependent scratching. Dimaprit (H(2) agonist, 0.04-40 micromol) did not cause scratching. Mepyramine (H(1) antagonist, 20 mg kg(-1), i.p.) reduced scratching evoked by histamine and HTMT, but not that caused by H(3) or H(4) agonists. Thioperamide (H(3)/H(4) antagonist, 20 mg kg(-1), i.p.) reduced scratching induced by histamine, H(3) and H(4) agonists, but not that caused by HTMT. The non-sedating H(1) antagonist, terfenadine, also significantly reduced the scratching induced by the H(1) agonist, HTMT. Cimetidine (H(2) antagonist, 20 mg kg(-1), i.p.) did not affect histamine-induced scratching. These results indicate that activation of histamine H(4) receptors causes itch in mice, in addition to the previously recognised role for H(1) receptors in evoking itch. Histamine H(4) receptor antagonists therefore merit investigation as antipruritic agents.
A New Rotary Compressor (1943)

The author shows how the helical lobe compressor originated during his development of the gas turbine, as he became convinced that a general solution of the gas turbine problem could be reached by means of the constant-pressure cycle with centrifugal compressors of the multistage type. Trouble with “pumping” in the compressor led to an examination of the possibilities of a displacement type running at high peripheral speed. After examination of a modified Roots type and of a conical screw compressor, the helical lobe compressor was developed. A comparison of the three types is given and various points of design are discussed. Various methods of increasing the efficiency are considered and the paper concludes with notes on compression ratios, methods of control, and the manufacture of the rotors.
High signal-to-noise detection of rotational Raman scattering through refluorescent and dispersive atomic filters (2000)

We introduce new methods for capturing rotational Raman scattering that simultaneously suppress background scattering and have exceedingly high spectral dispersion at low wavenumbers. These methods are based on resonant absorption and refractive index dispersion of atomic vapor, and take advantage of the availability of tunable lasers. Three different configurations are presented. The first is an atomic notch transmission filter which is based on refluorescence from an optically thick atomic vapor cell. This configuration is demonstrated in air using mercury vapor at 254 nm. The second configuration is an atomic resonance prism cell which is demonstrated in CO2 using mercury vapor, again at 254 nm. The third configuration is a density gradient atomic vapor cell which uses rubidium vapor at 780 nm. In the last two configurations, the atomic cell simultaneously blocks the elastic scattering while spatially dispersing the rotational Raman lines. In each case, a tunable Ti : sapphire laser was employed as an illuminating source. Copyright © 2000 John Wiley & Sons, Ltd.
Study on poly(vinyl chloride) paste blending resins (1996)

Abstract Polyvinyl chloride paste blending resins were prepared by a suspension polymerization process, and the optimum ingredients and technological conditions were studied experimentally. The effect of dispersant, surfactant, and agitator design on the particle morphology was discussed. In order to improve the thermal stability of the blending resin, stabilizer was added to the polymerization system, and a special after‐treatment was adopted. The effect of blending resins on the rheological and gelation characteristics of the plastisols formed and on mechanical properties, thermal stability, and foamability of the finished articles is demonstrated.
Beneficial effects of better control of secondary hyperparathyroidism with paricalcitol in chronic dialysis patients (2009)

Paricalcitol efficiently suppresses PTH secretion in dialysis patients with SHPT, with a moderate calcemic, but not a phosphatemic, effect. The dose of paricalcitol calculated as iPTH/80 may cause acute lowering of bone turnover. The improvement of anemia control and the amelioration of acid-base balance are 2 important additive effects of the better control of SHPT that may improve survival of hemodialysis patients.
Overexpression of Brain Natriuretic Peptide Facilitates Neutrophil Infiltration and Cardiac Matrix Metalloproteinase-9 Expression After Acute Myocardial Infarction (2004)

These results demonstrate that elevated plasma BNP facilitates neutrophil infiltration of the infarcted area after MI and increases the activity of the MMP-9 they produce. This suggests that BNP plays a key role in the processes of extracellular matrix remodeling and wound-healing during the early phase after acute MI.

Prejudice Is More than Black and White. (1988)

Mutations in the Presenilin 2 gene (PSEN2) represent the less frequent genetic cause of familial Alzheimer's disease (FAD). Only eight PSEN2 mutations, reported in approximately 27 families, satisfied strict criteria of pathogenicity. We reported a patient with early-onset FAD and the PSEN2 p.Met239Ile mutation, presenting with severe executive dysfunction and myoclonic tremor, associated with memory loss. Brain SPECT study showed an early hypoperfusion of the frontal cortex. We confirmed the pathogenicity of PSEN2 p.Met239Ile mutation and its heterogeneous phenotypic expression. The modulating effect of the Apolipoprotein E and Prion Protein gene polymorphisms on the phenotypic variability was not confirmed.
The selection and application of ssDNA aptamers against MPT64 protein in Mycobacterium tuberculosis (2009)

Active immunotherapy with viral lysates of micrometastases following surgical removal of high risk melanoma (1992)

Patients who develop lymph node metastases from melanoma are known to be at risk of developing further recurrences from melanoma following surgical removal of lymph node metastases. The purpose of the present study was to examine whether immunization over a 2 year period with a vaccine made from vaccinia viral lysates of an allogeneic melanoma cell (VMCL), following surgical removal of lymph node metastases, would help prevent the development of distant metastases and improve survival from the disease. Eighty patients treated with VMCL alone and followed for a minimum of 5.5 years had improved survival compared to a historical control group of 151 patients and a concurrent non-randomized group of 55 patients. Similarly, the survival of 102 patients treated with VMCL + low dose cyclophosphamide for a minimum of 3.5 years was superior to that of the historical control group but not to that of the VMCL alone treated group. Improvement in survival was still evident when this was measured from the date of removal of the primary tumor. Analysis of subsets of patients showed that VMCL treatment appeared to benefit patients irrespective of the number of lymph nodes involved and whether surgery was carried out near to (synchronous metastases) or some time after removal of the primary (delayed metastases). Analysis of the effect of treatment on duration to development of distant metastases suggested that there was a lower proportion of metastases during treatment with VMCL compared to the historical control groups. Treatment with VMCL also appeared to be associated with a lower incidence of cutaneous metastases but a higher proportion of visceral (including liver) metastases. Treatment was not associated with prolongation of survival after development of distant metastases. The results from this prolonged follow-up provide further support for an apparent survival benefit from immunotherapy with VMCL and suggest that the duration to and site of distant metastases is altered by this treatment. A randomized control (Phase III) study based on these results is in progress.
Rough grammar for efficient and fault-tolerant computing on a distributed system (1991)

A method that combines global load balancing with dynamic task scheduling on a multiprocessor machine is presented. This method does not require prior knowledge of the run times of tasks, and is based on a rough grammar representing distributed computation is presented. Production rules are dynamically constructed when a concurrent program is run. The set of the rough grammar production rules is updated and rolled in a pipeline fashion, together with codes of the processes. This pipeline fashion of rolling the jobs defines the global job balancing. The rough grammar uses any operators and metrics, not only concatenation, inside its production rules. Performance parameters for the combination of a global load balancing and decentralized dynamic task scheduling are derived and compared with those for a statically scheduled multiprocessor. Based on these parameters, the decentralized methodology is shown to attain a much higher performance level and a highly improved fault tolerance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Observation of photon localization in a three-dimensional disordered system (1991)

The diffusion and absorption coefficients of microwave radiation in random mixtures of metallic and dielectric spheres are determined from measurements of the intensity correlation function with frequency shift and of the scale dependence of transmission. We find a narrow window of localization in frequency and metallic concentration. The transition is rounded by the presence of absorption.
Formulas for direct frequency modulation response of two-electrode diode lasers: proposals for improvement (1987)

Semiconductor lasers, ModulationFormulas for the frequency and amplitude small-signal modulation response are given with nonlinear gain taken into account. The importance of the phase characteristic is discussed. Curves are shown of the modulus and phase of the frequency modulation for some selected cases and a method is proposed to obtain nearly ideal response.
Effects of internal free calcium upon the sodium and calcium channels in the tunicate egg analysed by the internal perfusion technique. (1978)

1. The unfertilized egg of the tunicate, Halocynthia roretzi, was intracellularly perfused with various solutions. 2. The perfusion apparatus consisted of lower and upper compartments which were connected by a small glass funnel. A denuded egg cell without chorion was dropped into the funnel and brought into close contact with the glass wall of the funnel. The membrane of the egg faced to the lower compartment was ruptured by a slight difference of hydrostatic pressure and the inside of the egg was perfused with the internal solution flowing through the lower compartment. The current across the upper membrane was analysed by voltage-clamp technique. 3. The egg cell in contact with 400 mM-Na external solution and perfused intracellularly with 400 mM-Na for 30 min showed a relatively low Na reversal potential, +6 mV, in comparison with +60 mV in the intact egg in standard artificial sea water. The exchange efficiency was monitored by observing the shift of Na reversal potential during perfusion with high Na internal perfusate. 4. The internal perfusate containing F- ions stabilized the egg membrane and kept the excitability for 1--2 hr during the intracellular perfusion. With the internal F- perfusate the intracellular cationic content was changed to 400 mM-Na, K, Rb or Cs (external solution of 400 mM-Na) and permeability ratios of the egg Na channel were estimated as PNa:PK:PRb:PCs=1.0:0.14:0.05:0.04. The internal F- perfusate abolished Ca current which was consistently observed in the intact egg, while the internal Cl- perfusate kept both Na and Ca current as in the intact egg. However with the internal Cl- perfusate the egg cell could not be kept in good condition more than 20-30 min. 6. The effects of intracellular free Ca ions upon the egg Na and Ca channels were analysed by using Ca ion-buffered internal Cl- and high Na perfusate. The results showed that internal Ca ions above 10(-6) reduced the Ca current and enhanced the Na current at the same time. In the range between 10(-5) and 10(-4) M the Ca current became half of the control obtained with zero free Ca perfusate while the Na conductance at the zero current level doubled. The internal Ca ions above one mM seemed to abolish the Ca current and to reduce the Na current as well. The reciprocal effect of intracellular Ca ions upon the egg Na and Ca channels was demonstrated in the concentration range from 10(-6) to 10(-3) M.
