Consistent line clusters for building recognition in CBIR (2003)

This paper introduces a new mid-level feature, the consistent line cluster for use in content-based image retrieval. The color, orientation, and spatial features of line segments are exploited to group them into line clusters. The interrelationships among different clusters and the intra relationships within single clusters are used to recognize and roughly locate buildings in photographic images. Experiments are performed on a database of color images of outdoor scenes.
Tau-Induced Pathology in Epilepsy and Dementia: Notions from Patients and Animal Models (2018)

Patients with dementia present epilepsy more frequently than the general population. Seizures are more common in patients with Alzheimer's disease (AD), dementia with Lewy bodies (LBD), frontotemporal dementia (FTD) and progressive supranuclear palsy (PSP) than in other dementias. Missense mutations in the microtubule associated protein tau (MAPT) gene have been found to cause familial FTD and PSP, while the P301S mutation in MAPT has been associated with early-onset fast progressive dementia and the presence of seizures. Brains of patients with AD, LBD, FTD and PSP show hyperphosphorylated tau aggregates, amyloid-β plaques and neuropil threads. Increasing evidence suggests the existence of overlapping mechanisms related to the generation of network hyperexcitability and cognitive decline. Neuronal overexpression of tau with various mutations found in FTD with parkinsonism-linked to chromosome 17 (FTDP-17) in mice produces epileptic activity. On the other hand, the use of certain antiepileptic drugs in animal models with AD prevents cognitive impairment. Further efforts should be made to search for plausible common targets for both conditions. Moreover, attempts should also be made to evaluate the use of drugs targeting tau and amyloid-β as suitable pharmacological interventions in epileptic disorders. The diagnosis of dementia and epilepsy in early stages of those diseases may be helpful for the initiation of treatments that could prevent the generation of epileptic activity and cognitive deterioration.
Biomimicry of bacterial foraging for distributed optimization and control (2002)

We explain the biology and physics underlying the chemotactic (foraging) behavior of E. coli bacteria. We explain a variety of bacterial swarming and social foraging behaviors and discuss the control system on the E. coli that dictates how foraging should proceed. Next, a computer program that emulates the distributed optimization process represented by the activity of social bacterial foraging is presented. To illustrate its operation, we apply it to a simple multiple-extremum function minimization problem and briefly discuss its relationship to some existing optimization algorithms. The article closes with a brief discussion on the potential uses of biomimicry of social foraging to develop adaptive controllers and cooperative control strategies for autonomous vehicles. For this, we provide some basic ideas and invite the reader to explore the concepts further.
Preparation of Colloidal Gold (2009)

Colloidal gold probes have become widely used for immunocytochemical staining at the electron microscopic level. Gold sols are producing by boiling a solution of tetrachloroauric acid with a reducing agent. The type of reducing agent and the concentration of components determine the final particle size. Gold sols that have a particle size ranging from 2 to 40 nm can be made in the laboratory, depending on the type and concentration of the reducing agent. This chapter details methods for producing various sizes of gold. The methods are relatively simple and very reproducible from batch to batch.
<title>LEO thermal imagers: push broom or whisk broom?</title> (1992)

LEO Thermal imaging is controlled by two parameters: t<SUB>o</SUB> time need to scan the foot print along the track and t<SUB>i</SUB> integration time in thermal band. It is known that whisk broom is adequate when t<SUB>o</SUB> > > t<SUB>i</SUB> (low resolution) and push broom is of interest when t<SUB>o</SUB> is congruent to t<SUB>i</SUB> (high resolution). However moderate size projects are limited to low or intermediate resolution (for 30 m, t<SUB>o</SUB> is about two orders of magnitude greater than t<SUB>i</SUB>) and push broom is not mandatory. The need for high frequency calibration to eliminate 1/f detector noise (especially for (lambda) > 11 micrometers ) makes push broom advantage smaller than expected. Microscanning can be thought of as a way to match t<SUB>o</SUB> and t<SUB>i</SUB> as well as a convenient calibration mechanism. A configuration mixing microscanning and push broom design is shown to be a very efficient compromise. Problems like detector butting, fast calibration, long life time mechanism, and signal processing at chip level are more easily solved within the proposed concept.
Theft of Information in the Take-Grant Protection Model (1995)

Questions of information flow are in many ways more important than questions of access control, because the goal of many security policies is to thwart the unauthorized release of information, not merely the illicit obtaining of access rights to that information. The Take-Grant Protection Model is an excellent theoretical tool for examining such issues because conditions necessary and sufficient for information to flow between two objects, and for rights to objects to be obtained or stolen, are known. In this paper we extend these results by examining the question of information flow from an object the owner of which is unwilling to release that information. Necessary and sufficient conditions for such “theft of information” to occur are derived. To emphasize the usefulness of these results, the security policies of complete isolation, transfer of rights with the cooperation of an owner, and transfer of information (but not rights) with the cooperation of the owner are presented; the last is used to model a subject guarding a resource.
Subjective and objective features of sore throat (1984)

• This study examines the relationship between the symptom of sore throat and the signs of pharyngitis. Patients seeking medical attention for sore throat were examined by their physician, who documented findings on a Tonsillopharyngitis Score (TPS) and obtained a throat culture. Each patient was then instructed by the physician's assistant to characterize the severity of throat pain on a Sore Throat Pain Intensity Scale (STPIS) and Sore Throat Questionnaire. A high positive correlation was found for the STPIS and TPS but not for these findings and the cause of pharyngitis. A similar association was found between the relative severity of throat pain and the words patients use to describe it. This new method objectively confirms the subjective rating of sore throat pain.

Ensemble of Multilayer Perceptrons for Change Detection in Remotely Sensed Images (2013)

In this letter, a change detection technique using a multiple classifier system is proposed. Here, different architectures of multilayer perceptron (MLP) are used as base classifiers. An ensemble of different MLPs is utilized to increase the robustness of the system. This also avoids the problem of choosing an optimum architecture for MLP. First, the support values for each of the unlabeled patterns are estimated using different MLPs (trained with the labeled patterns). Then, each of the unlabeled patterns is assigned to a specific class by fusing the outcome of the base classifiers using different combination rules. Experiments are carried out on multitemporal and multispectral images. Results show that the proposed ensemble technique has an edge over individual base classifiers for change detection in remotely sensed images.
QR Codes in Print Advertising: Elucidating Indian Vogue Using Content Analysis (2013)

Last couple of years observed tremendous growth in QR Code usages in advertising worldwide. But, there is lack of knowledge on orientation of QR Code usage and various trends related to it like linkage with incentives, e-content encoding etc. Further, many expert opine that current application of QR Codes in advertising is somewhat causal and ineffective. This study attempts a preliminary investigation of above issues in print media, using content analysis approach. Analysis of data collected over one year in India suggested that consumer goods marketers are predominantly deploying QR Codes; majority QR Codes are not linked to incentives and QR Codes are mainly used for informative purpose. Analysis further suggested ineffective offline and online application of QR Codes in print advertising. At last, the study gives important implications for marketers and scope of further research.
Single image super-resolution using iterative Wiener filter (2012)

In this paper, we propose an iterative Wiener filter which can simultaneously perform interpolation and restoration by using non-local means to directly model the correlation between the desired high-resolution image and observed low-resolution image. A novel mechanism is proposed to control the decay speed of the correlation function while iteratively updating both estimated correlation and high-resolution image. During the iterations, the image is decomposed into patches with similar intensities at initial iterations and the patches are connected naturally with good convergence. Experimental results show that the proposed algorithm is able to produce natural image structures, and provides better PSNR and visual quality than the state-of-the-art algorithms using the sparse representation and natural image priors.

Mammalian iron homeostasis is maintained through the concerted action of sensory and regulatory networks that modulate the expression of proteins of iron metabolism at the transcriptional and/or post-transcriptional levels. Regulation of gene transcription provides critical developmental, cell cycle, and cell-type-specific controls on iron metabolism. Post-transcriptional control through the action of iron regulatory protein 1 (IRP1) and IRP2 coordinate the use of messenger RNA-encoding proteins that are involved in the uptake, storage, and use of iron in all cells of the body. IRPs may also provide a link between iron availability and cellular citrate use. Multiple factors, including iron, nitric oxide, oxidative stress, phosphorylation, and hypoxia/reoxygenation, influence IRP function. Recent evidence indicates that there is diversity in the function of the IRP system with respect to the response of specific IRPs to the same effector, as well as the selectivity with which IRPs modulate the use of specific messenger RNA.
Hesitation Phenomena in Spontaneous English Speech (1959)

[This paper reports an exploratory investigation of hesitation phenomena in spontaneously spoken English. Following a brief review of the literature bearing on such phenomena, a quantitative study of filled and unfilled pauses, repeats, and false starts in the speech of some twelve participants in a conference is described. Analysis in terms of both individual differences and linguistic distribution is made, and some psycholinguistic implications are drawn, particularly as to the nature of encoding units and their relative uncertainty. A distinction between non-chance statistical dependencies and all-or-nothing dependencies in linguistic methodology is made.]
Local and global calibration for high-resolution doa estimation in automotive radar (2008)

Calibration of an antenna array is very important for high-resolution direction-of-arrival (DOA) estimation. In this paper, we study this issue for an automotive frequency modulated continuous wave (FMCW) radar whose low-cost dielectric lens antenna causes, in addition to the coupling between sensor elements and gain or phase mismatch, direction-dependent perturbations to the sensor response. We apply both global and local calibration methods and compare their performance.

Neuronal Type-Specific Gene Expression Profiling and Laser-Capture Microdissection (2011)

The human brain is an exceptionally heterogeneous structure. In order to gain insight into the neurobiological basis of neural circuit disturbances in various neurologic or psychiatric diseases, it is often important to define the molecular cascades that are associated with these disturbances in a neuronal type-specific manner. This can be achieved by the use of laser microdissection, in combination with molecular techniques such as gene expression profiling. To identify neurons in human postmortem brain tissue, one can use the inherent properties of the neuron, such as pigmentation and morphology or its structural composition through immunohistochemistry (IHC). Here, we describe the isolation of homogeneous neuronal cells and high-quality RNA from human postmortem brain material using a combination of rapid IHC, Nissl staining, or simple morphology with Laser-Capture Microdissection (LCM) or Laser Microdissection (LMD).
The prospects for polyester polymer-CdS powder composites in photoelectronic device applications (1989)

The optoelectronic properties of polyester polymer-CdS composite were investigated, as a function of component weight ratio, electric field strength and light intensity. Cl and Cu activated CdS powder as well as unactivated CdS powder were added to polyester polymer. It has been shown that the composite containing 60-70 wt.% of CdS has the best photoelectric properties. The ratio of photocurrent to dark current was greater than 108 for white illumination of approximately 225 mW cm-2. The electrophotographical layers of this composite exhibited a photosensitivity as high as 1.25 lx-1 s-1. The results have been explained in terms of the reduction in interparticle barrier height assisted by the localised trapping of photoexcited or field excited holes.
O aporte marxista da educação brasileira no contexto da resistência e da transição democrática (1998)

Na passagem das décadas de 1970-1980, emerge no Brasil uma produção educacional fortemente marcada pelos influxos da tradição marxista, em consonância com a tendência oposicionista do período. Tal produção assume características peculiares devido à convergência de um conjunto de fatores: a ausência de acumulação marxista pregressa nesse campo, o adensamento político propiciado pelo engajamento dos educadores no conjunto das lutas oposicionistas, as reorganizações do campo educacional, com a reativação de eventos e entidades nacionais e o estabelecimento do sistema nacional de pós-graduação. O presente trabalho discute a natureza da incidência marxista, relacionando-a as condições históricas que conformaram tal produção intelectual.
Phase Center Calibration and Multipath Test Results of a Digital Beam-Steered Antenna Array (2003)

For precision GPS applications, such as GPS reference sites, antenna calibration is needed to characterize and compensate for carrier phase distortions caused by the antenna. This is generally attributed to two sources: phase center motion dependent on the satellite direction, and phase offsets caused by local multipath. The ability to reduce these error sources is critical for high accuracy kinematic GPS applications. In this paper a digital beam-steered antenna array is described that has the capability to perform built-in calibration and characterization of carrier phase errors. The calibration process and test results showing the kinematic GPS performance possible with this receiver are described in this paper.
Draining our Glass: An Energy and Heat Characterization of Google Glass (2014)

The Google Glass is a mobile device designed to be worn as eyeglasses. This form factor enables new usage possibilities, such as hands-free video chats and instant web search. However, its shape also hampers its potential: (1) battery size, and therefore lifetime, is limited by a need for the device to be lightweight, and (2) high-power processing leads to significant heat, which should be limited, due to the Glass' compact form factor and close proximity to the user's skin. We use the Glass in a case study of the power and thermal characteristics of optical head-mounted display devices. We share insights and implications to limit power consumption to increase the safety and utility of head-mounted devices.

Emulsionspolymerisation und Kunststoff‐Latices (1960)

Abstract Bei der Emulsionspolymerisation mit Emulgatoren startet die Reaktion in der wäßrigen Phase, verläuft anfangs vorwiegend in den Emulgatormicellen, später in den entstandenen Latexteilchen. Größe und Größenverteilung der Latexteilchen lassen sich durch die Reaktionsbedingungen und die Polymerisationstechnik beeinflussen. Die Stabilität der Kunststoff‐Latices hängt vor allem von der Teilchenladung, der Art der Schutzkolloide und den Eigenschaften der Solvathülle ab.
Evaluation of anticonvulsant drugs in DBA/2 mice with sound-induced seizures. (1984)

The syndrome of sound-induced seizures in DBA/2 mice is described. Protection against seizure responses is provided by intraperitoneal administration of conventional anticonvulsant drugs with benzodiazepines being the most potent, and valproate, ethosuximide and trimethadione the least potent. Protection is also provided by intracerebroventricular administration of anticonvulsant drugs. GABAergic agents, antagonists of excitation due to dicarboxylic amino acids, alpha 2-noradrenergic agonists, and dopamine agonists all provide protection against the seizure responses. There is, however, no conclusive biochemical evidence that the syndrome is attributable to a defect in one or more of these neurotransmitter systems.

Sketchy Lesbians: Carol as History and Fantasy (2015)

Rather than a forward-looking lesbian representation, Todd Haynes's Carol, an adaptation by Phyllis Nagy of Patricia Highsmith's 1952 novel, The Price of Salt, looks to images and affective investments of the past to explore lesbian representability, the historical discourses and aesthetic codes through which desire between women can be recognized. The collaboration brings together preoccupations from Haynes's oeuvre and themes from Highsmith's that question reception of the film in terms of a happy ending and future progress. Through evocative art direction, camerawork, and star performances, the film invites the viewer to share the perspective of Therese (Rooney Mara), a nearly blank character written as Highsmith's stand-in, who is subsumed by desire for Carol (Cate Blanchett), a wealthy, discontented suburban wife and mother whom she meets by chance. The lovers’ exclusivity, and even their persecution, are understood as elements of fantasy that ultimately shed light on queer history.
Optimization of Dissolved Solids for the Intensive Culture of Juvenile Red Drum <i>Sciaenops ocellatus</i> (1995)

Abstract Survival and growth of 0.3–0.9 g red drum Sciaenops ocellatus were measured for fish reared in water‐recirculating culture systems containing one of the following media: 6g/L diluted seawater; 1g/L diluted seawater; 1g/L diluted seawater with either 1 or 5g/L of additional salt. Salt was added as sodium chloride, calcium chloride, or magnesium sulfate. Mean survival over the 42‐d study period was 56.3%. The 5g/L sodium chloride treatment had the highest survival rate (80.0%) and the calcium chloride treatment had the lowest (26.7%). The biomass‐change rate for fish in the 5g/L calcium chloride treatment was significantly lower ( P < 0.05) than for fish in the 5g/L sodium chloride, 1g/L sodium chloride, or 5g/L magnesium sulfate treatments. The latter three treatments gave biomass‐change rates that did not differ ( P > 0.05) from those obtained in the 1 or 6g/L diluted seawater.
Optical networks in the real world (2002)

Current optical transmission systems (currently based on the SONET or SDH standards in particular) provide many features that aid an operator in determining system performance, system status, and help to isolate faults. As the need for data transmission is growing rapidly in the network, the desire to transport Internet Protocol (IP) frames over optical systems arises, in addition to traditional time division multiplexed (TDM) telephony voice and data signals.
Omega-3 fatty acids as treatments for mental illness: which disorder and which fatty acid? (2007)

While it is not currently possible to recommend omega-3 PUFA as either a mono- or adjunctive-therapy in any mental illness, the available evidence is strong enough to justify continued study, especially with regard to attentional, anxiety and mood disorders.
