Integrated human target detection, identification and tracking for surveillance applications (2012)

In recent years, a large amount of research efforts have been spent in the tracking human targets using one or more visual sensors (cameras) in both indoor and outdoor security and surveillance environments such as airports, metro stations, etc. However, in majority, the problem of associating a reliable identification signature to a detected target when in motion, has often been complicated due to changing target appearance, changes in lighting conditions and also because of partial or full occlusion. Therefore control operators have always been engaged in supervising the process of tagging specific targets of interest. Although the complementary field of human target identification based on biometrics (particularly via face recognition) has been well researched and mature enough; not much efforts has been directed in combining these technologies in-order to make security and surveillance operations fully autonomous. In this paper, this integration of simultaneous detection, tracking, and face-recognition-based identification of human targets from a static camera is proposed. The accuracy, efficiency and robustness of the this proposed framework is assessed and illustrated over different standard datasets across a wide range of scenarios using appropriate performance metrics.
Downregulation of Carnitine Acyl-Carnitine Translocase by miRNAs 132 and 212 Amplifies Glucose-Stimulated Insulin Secretion (2014)

We previously demonstrated that micro-RNAs (miRNAs) 132 and 212 are differentially upregulated in response to obesity in two mouse strains that differ in their susceptibility to obesity-induced diabetes. Here we show the overexpression of miRNAs 132 and 212 enhances insulin secretion (IS) in response to glucose and other secretagogues including nonfuel stimuli. We determined that carnitine acyl-carnitine translocase (CACT; Slc25a20) is a direct target of these miRNAs. CACT is responsible for transporting long-chain acyl-carnitines into the mitochondria for β-oxidation. Small interfering RNA-mediated knockdown of CACT in β-cells led to the accumulation of fatty acyl-carnitines and enhanced IS. The addition of long-chain fatty acyl-carnitines promoted IS from rat insulinoma β-cells (INS-1) as well as primary mouse islets. The effect on INS-1 cells was augmented in response to suppression of CACT. A nonhydrolyzable ether analog of palmitoyl-carnitine stimulated IS, showing that β-oxidation of palmitoyl-carnitine is not required for its stimulation of IS. These studies establish a link between miRNA-dependent regulation of CACT and fatty acyl-carnitine-mediated regulation of IS.
Bandwidth-Variable Bandpass Filter based on Dispersion Engineered Tapered Fiber with External Polymer Cladding (2009)

A simple thermo-optic bandwidth-variable fiber-based bandpass filter is demonstrated by using a tapered standard single mode fiber covered with a dispersive polymer layer. The 3 dB spectral bandwidth can be tuned from 250 nm with a Gaussian shape to 500 nm with a flat-top shape.
Lifetime prediction of 20 kV field-aged silicone rubber insulators via condition assessment (2017)

Field investigations of silicone rubber (SiR) insulators provide useful information about their performance. The field performance of SiR insulators depends on many factors, including electrical stress, and environmental and service conditions experienced. This paper provides a condition assessment of the housing material of five different types of 20 kV field-aged SiR insulators from the same manufacturer with different operating years and states. The assessment was performed through mechanical, electrical, and material techniques. The main objective of this paper is to investigate the aging behavior of SiR insulators, in order to predict their lifetimes. Thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR) were utilized to quantify the degree of degradation. The mechanisms of the variations in mechanical properties for aged samples were also discussed. In a tensile test, the reduction of strain-to-break to 50% and in other tests the failure of insulators in salt fog chamber were used as the end of life criterion. Finally, the lifetime of the tested insulators was predicted based on the various aforementioned tests.
Prediction of Zonal Flow Allocation Using Fiber-Optics Monitoring In a Complex Injector Well System (2020)

Abstract Injector well completions are typically carried out using two methods: simple and selective. The performance of injector wells has traditionally been evaluated using spinner-based injection logging tools (ILTs) or on-demand fiber optic distributed temperature and acoustic (DTS or DAS) sensing while logging the well performance every 3 months or once a year depending on the application. However, with such methods utilizing a snap shot approach, critical well performance information or possible anomalies are often missed due to measurements taken only during certain periods. Therefore, operators have explored the use of advanced fiber-optics methods such as permanent distributed temperature sensing (DTS) and permanent distributed acoustic sensing (DAS), that provide continuous, real-time measurements to enable understanding of dynamic well behavior at all times and mitigate any deferred or behavioral problems. Of relevance to this work is a vertical, injector well in a competent sandstone formation of the Heavy Oil Chichimene field in Llanos Basin, Colombia. As a first step of the fiber-optics monitoring strategy, a careful evaluation of DTS and DAS based fiber-optics methods was conducted. Based on the data analysis and operational history, DAS-based fiber optics monitoring was chosen as the most effective monitoring solution for this well. Subsequently, a proprietary DAS algorithm was developed to analyze the data and estimate the flow allocation for all the four zones. The results include waterfall acoustic energy maps, temporal flow allocation profiles and most importantly, the zonal flow allocation values. Predicted (DAS) zonal flow allocation data was compared with traditional injection logs (ILT) under different operational conditions (varied injection flow rates and valve choke settings). Based on comparable agreement between DAS and ILT data, the operator decided to replace ILT runs with DAS-based fiber optic monitoring, resulting in lower operational costs while enabling near real-time monitoring, and providing the continuous distributed data essential for the dynamic monitoring of the well. The successful application of fiber-optics monitoring to provide an injection profile in conjunction with a surface-controlled electric valve system demonstrates a significant potential to optimize the injection process in complex injector wells. Further, remotely controlling, monitoring and optimizing injection rates into the multi-segmented zones improves the service life of the injection operations, eliminates future intervention costs, and increases ultimate recovery.
Multifunctional SWCNT‐ZnO Nanocomposites for Enhancing Performance and Stability of Organic Solar Cells (2010)

Ebulin from Dwarf Elder (Sambucus ebulus L.): A Mini-Review (2015)

Sambucus ebulus L. (dwarf elder) is a medicinal plant, the usefulness of which also as food is restricted due to its toxicity. In the last few years, both the chemistry and pharmacology of Sambucus ebulus L. have been investigated. Among the structural and functional proteins present in the plant, sugar-binding proteins (lectins) with or without anti-ribosomal activity and single chain ribosome-inactivating proteins (RIPs) have been isolated. RIPs are enzymes (E.C. 3.2.2.22) that display N-glycosidase activity on the 28S rRNA subunit, leading to the inhibition of protein synthesis by arresting the step of polypeptide chain elongation. The biological role of all these proteins is as yet unknown. The evidence suggests that they could be involved in the defense of the plant against predators and viruses or/and a nitrogen store, with an impact on the nutritional characteristics and food safety. In this mini-review we describe all the isoforms of ebulin that have to date been isolated from dwarf elder, as well as their functional characteristics and potential uses, whilst highlighting concern regarding ebulin toxicity.
Molecular Size Distribution ofImmunoreactive Trypsin and Renal Tubular Dysfunction:Role in Trypsin Plasma-Urine Transfer (1987)

In order to investigate the role of circulating free trypsinogen and renal tubular dysfunction in affecting trypsin plasma-urine transfer, serum immunoreactive trypsin (IRT), its urinary output, IRT molecular size distribution, filtrable immunoreactive trypsin, gamma-glutamyltransferase and alpha-glucosidase outputs were studied in 6 control subjects, 9 patients with pancreatic cancer and 15 with chronic pancreatitis. The majority of immunoreactivity was always eluted at a molecular weight of about 24,000 and might therefore be considered as free trypsinogen. Variable amounts of IRT at higher molecular weights, possibly represented by trypsin-inhibitor complexes, were also detected. Increasing IRT levels were generally accounted for by free trypsinogen, regardless of the nature of the disease. Unlike serum free trypsinogen levels, renal tubular damage, evaluated by means of the excretion of two high-molecular weight urinary enzymes, seems to play a prominent role in explaining trypsin plasma-urine transfer.
The how and the what of leadership. (2012)

Psychological theories view leadership as a social influence process in which leaders use interpersonal behaviors to motivate followers to contribute to group goals. On the other hand, business-oriented models emphasize the leadership of organizational functions such as strategy, structure, staffing, and work systems. In this article, this distinction is conceptualized as representing the interpersonal how and the organizational what, respectively, and the two perspectives are viewed as complementary ways that leaders can impact organizational performance. Evidence is provided to show how leadership professionals tend to have a bias in favor of one, and corresponding neglect of the other, perspective. A study is then presented to test relationships between behaviors indicative of the how and the what and leadership effectiveness. Based on ratings of 421 senior managers from 4,670 superiors, peers, and subordinates, the results demonstrate the significant and roughly equivalent contributions for both the interpersonal how and the organizational what in predicting the perceived effectiveness of leaders and the unique routes through which each aspect of leadership affects team performance. Implications for research and practice are discussed in terms of integrative, multidisciplinary approaches to understanding and improving leadership.
Integrity in Automated Information Systems (1991)

Abstract : For many years, the security research community has focused on the confidentiality aspect of security, and a solid analytical foundation for addressing confidentiality issues has evolved. Now it is recognized that integrity is at least as important as confidentiality in many computer systems; it is also apparent that integrity is not well understood. The purpose of this paper is to lay a foundation for understanding integrity and investigate how it can be promoted and preserved in computer systems. The paper begins by exploring what is meant by integrity. It identifies three primary sub goals of integrity: (1) prevent unauthorized users from accessing system resources or modifying data, (2) maintain traditional data consistency, as well as the consistency of a system with respect to its environment, and (3) prevent authorized users from improperly accessing system resources or modifying data. Having articulated a vision of integrity, the paper discusses principles underlying the preservation of integrity, analyzes manual and automated integrity-preserving mechanisms, and examines integrity models and proposed implementations of the models. The paper concludes that although some gaps in understanding still exist, it is possible to begin to standardize integrity properties of systems.
Data from Transforming Growth Factor-β Promotes Invasion in Tumorigenic but not in Nontumorigenic Human Prostatic Epithelial Cells (2023)

&lt;div&gt;Abstract&lt;p&gt;Transforming growth factor-β (TGF-β) is a pleiotropic growth factor with actions that are dependent on circumstances, including dose, target cell type, and context. TGF-β can elicit both growth-promoting and growth-suppressive activities. In normal tissues, TGF-β generally acts to restrict growth and maintain differentiation. However, during tumorigenesis, changes in TGF-β expression and cellular responses can promote tumorigenesis. The present study examines the effects of TGF-β on the nontumorigenic human prostatic epithelial cell line BPH1 and on three derivative tumorigenic sublines BPH1&lt;sup&gt;CAFTD&lt;/sup&gt;1, BPH1&lt;sup&gt;CAFTD&lt;/sup&gt;3, and BPH1&lt;sup&gt;CAFTD&lt;/sup&gt;5. The data show that TGF-β has different effects on the nontumorigenic and tumorigenic cells. The nontumorigenic cells are growth inhibited by TGF-β. In contrast, the tumorigenic sublines are not growth inhibited but instead undergo an epithelial to mesenchymal transformation (EMT) in response to TGF-β. The tumorigenic lines show constitutively elevated levels of phosphorylated Akt, which modulates their response to TGF-β by blocking Smad3 and p21 nuclear translocation. On TGF-β stimulation of the tumorigenic sublines, the activated Akt allows the cell to escape cell cycle arrest. The phosphatidylinositol 3-kinase/Akt pathway is also involved in TGF-β-induced EMT, defined here by induction of vimentin expression and enhanced cellular motility. &lt;i&gt;In vivo&lt;/i&gt;, tumorigenic cells with constitutively active TGF-β signaling show increased invasion with EMT, which express vimentin, located specifically at the invasive front of the tumor. These data indicate that following malignant transformation TGF-β can play a direct role in promoting prostatic cancer and further that these responses are context specific &lt;i&gt;in vivo&lt;/i&gt;. (Cancer Res 2006; 66(16): 8007-16)&lt;/p&gt;&lt;/div&gt;
Vestibular Incision Subperiosteal Tunnel Access (VISTA) for Surgically Facilitated Orthodontic Therapy (SFOT) (2019)

Surgically Facilitated Orthodontic Therapy (SFOT) in combination with bone augmentation and the placement of anchorage devices installed into bone have been used to accelerate and facilitate orthodontic treatment. This is usually performed after flap surgery, which is associated with moderate morbidity, as well as possible negative sequale such as gingival recession. The present case report illustrates the clinical benefits of vestibular incision subperiosteal tunnel access (VISTA) for SFOT, and tissue augmentation to facilitate orthodontic therapy. VISTA entails making vertical incision(s) in the vestibule followed by subperiosteal elevation of tunnels to provide direct access to the facial alveolar bone. Unlike previously reported vestibular access surgical procedures, VISTA allows for wider elevation of an access tunnel for clear visual and surgical access to perform careful inter-radicular corticotomy. The present report describes VISTA for corticotomy surgery (anterior mandible and maxillary teeth) in combination with the placement of titanium fixation devices and bone augmentation to facilitate orthodontic treatment of an adult female with borderline Class II Division 1 malocclusion, with excessive overjet and deepbite. In view of the fact that VISTA does not require surface incisions in the gingival margins or papillae, it potentially minimizes gingival recession that sometimes accompanies flap surgery.
Antenna miniaturization with ferrite ferroelectric composites (2008)

Abstract A magneto‐dielectric composite with nickel zinc ferrite and bismuth strontium titanate has been synthesized and characterized in terms of permeability and permittivity and used as substrates for antenna miniaturization. The objective was to achieve high‐ and equal permeability and permittivity for antenna miniaturization and impedance matching to free‐space. Studies on antennas operating at 100 MHz indicate low‐losses and a miniaturization factor of 7–10, in agreement with theory. But a 1.3 GHz microstrip antenna on the composite substrate, however, shows high losses and miniaturization by a factor of 3. Theoretical estimates on antenna properties are compared with data. © 2008 Wiley Periodicals, Inc.

Structure of yeast phenylalanine-t: segment within the region coding f, (2016)

Sixteen bacterial clones containing sequences complementary to yeast Phe-tRNA were isolated from a col- lection of hybrid plasmids containing BamHI restriction en- donuclease-generated yeast DNA fragments inserted in the plasmid vector pBR315. Ten of these clones contained hybrid plasmids with distinct BamHI fragments. The sequence of the Phe-tRNA structural genes and adjacent regions of three of these clones is reported here. In the region flanking the tRNA gene, the sequence of two of the cloned DNAs is similar; the sequence of the third varies considerably. All three of the tRNA genes are bordered by A,T-rich regions. In particular, near the region coding for the 3' end of the tRNA there is a long sequence of As in the coding strand. This is reminiscent of the region of ter- mination of transcription of the yeast 5S rRNA gene. The se- quences coding for the Phe-tRNA contain an additional segment of 18 or 19 base pairs (depending upon the clone) not predicted by the yeast Phe-tRNA sequence. These intervening segments are nearly identical in the three clones and are located within the structural gene, two base pairs from the nucleotides coding for the tRNA anticodon. It is axiomatic that knowledge of the organization and structure of eukaryotic genes will clarify some of the mysteries of their expression and regulation. In order to study the factors required for specific transcription of ribosomal genes, we have recently determined the nucleotide sequence of a substantial fraction of the 9000-base-pair yeast ribosomal DNA repeat which contains both the 35S ribosomal precursor (transcribed by RNA polymerase I) and the 5S rRNA genes (transcribed by RNA polymerase III) (1-3). Inspection of the flanking sequences of the 5S rRNA gene (which appears to be an unprocessed gene product) showed a striking A-rich sequence in the coding strand
Tunable CMOS low-voltage linear transconductor and its application to HF GM-C filter design (2003)

A new CMOS low-voltage linear transconductor for High Frequency (HF) applications is presented. It uses tunable floating batteries between the input and the transistor gates of each inverter that forms the transconductor. The proposed transconductor operates under constant low voltage supply and transconductance and output resistance are independently tunable. It is suitable to be used in HF continuous time filters with programmable center frequency and quality factor.

Long-distance soliton propagation using lumped amplifiers and dispersion shifted fiber (1991)

It is shown both analytically and by numerical simulation, that solitons can traverse great distances through a chain of lumped amplifiers connecting dispersion shifted fiber spans. The fiber spans can also have large fractional variations in D. The resultant pulse distortions and dispersive wave radiation tend to be negligible, as long as the length scale of the variations in energy and dispersion are short relative to the soliton period.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Radiation assurance for the space environment (2004)

The space radiation environment can lead to extremely harsh operating conditions for spacecraft electronic systems. A hardness assurance methodology must be followed to assure that the space radiation environment does not compromise the functionality and performance of space-based systems during the mission lifetime. The methodology, outlined in this paper, includes a definition of the radiation environment, assessment of the radiation sensitivity of parts, worst-case analysis of the impact of radiation effects, and part acceptance decisions which are likely to include mitigation measures.
