Performance Enhancement of an Orbital-Angular-Momentum-Based Free-Space Optical Communication Link through Beam Divergence Controlling (2015)

Using beam divergence controlling to mitigate angular error effects in OAM-based FSO links is investigated through simulation and experiment. Results show that controlling beam divergence allows reducing power loss and angular error induced channel crosstalk.
Security System with Face Recognition, Sms Alert and Embedded Network Video Monitoring Terminal (2013)

Even though there are various security systems consuming large power are available in market nowadays, robbery rate is very high. We are proposing a novel system to prevent robbery in highly secure areas with lesser power consumption. This system has face-recognition technology which grants access to only authorized people to enter that area. If others enter the place without access using some other means, then the system alerts the security personnel and streams the video captured by the security camera. The facerecognition is done using PCA algorithm. The video transmitted is compressed and transmitted by ENVMT. By using this ENVMT, the video can play with lesser bandwidth consumption, latency and jitter.
Management of nipple pain and/or trauma associated with breast-feeding (2003)

In terms of prevention, warm water compresses are recommended for the prevention of nipple pain, and simply keeping the nipples clean and dry is recommended for the prevention of cracked nipples. In terms of treatment, warm water compresses are recommended for the reduction of nipple pain, and expressed breast-milk reduces the duration of cracked nipples. Hydrogel dressings were associated with a high incidence of infections and their use cannot be recommended. Systemic antibiotics are recommended if a positive culture for Staphylococcus aureus is obtained.Education for positioning and attachment of the baby to the breast for breast-feeding women needs further studies to assess whether it is more effective as a preventative measure for nipple pain and/or trauma. Warm water compresses warrant further investigation into their effectiveness in nipple pain. Studies assessing the impact of engorgement, pacifiers and feeding bottles on nipple pain and/or trauma are suggested.Further investigation of the interventions used in many of these studies could be conducted using one intervention at a time in comparison to no treatment. Specific research priorities should include RCTs to assess: (i) lanolin in comparison to no treatment; (ii) lanolin and shells in comparison to no treatment; and (iii) expressed breast-milk in comparison to no treatment.
Genomic complexity of urothelial bladder cancer revealed in urinary cfDNA (2016)

Urothelial bladder cancers (UBCs) have heterogeneous clinical characteristics that are mirrored in their diverse genomic profiles. Genomic profiling of UBCs has the potential to benefit routine clinical practice by providing prognostic utility above and beyond conventional clinicopathological factors, and allowing for prediction and surveillance of treatment responses. Urinary DNAs representative of the tumour genome provide a promising resource as a liquid biopsy for non-invasive genomic profiling of UBCs. We compared the genomic profiles of urinary cellular DNA and cell-free DNA (cfDNA) from the urine with matched diagnostic formalin-fixed paraffin-embedded tumour DNAs for 23 well-characterised UBC patients. Our data show urinary DNAs to be highly representative of patient tumours, allowing for detection of recurrent clinically actionable genomic aberrations. Furthermore, a greater aberrant load (indicative of tumour genome) was observed in cfDNA over cellular DNA (P<0.001), resulting in a higher analytical sensitivity for detection of clinically actionable genomic aberrations (P<0.04) when using cfDNA. Thus, cfDNA extracted from the urine of UBC patients has a higher tumour genome burden and allows greater detection of key genomic biomarkers (90%) than cellular DNA from urine (61%) and provides a promising resource for robust whole-genome tumour profiling of UBC with potential to influence clinical decisions without invasive patient interventions.
Administrators' Perceptions of Institutional Marketing (1993)

Changes in the environment of postsecondary institutions in the Western World have necessitated the adoption of strategies that were once thought to be incompatible with academic pursuit. Among these, is the increasing application of marketing techniques to attract vital resources in postsecondary institutions. This study investigated administrators' perceptions of various aspects of postsecondary institutional marketing in Alberta. Also, perceived problems and benefits of marketing practices in postsecondary institutions were investigated. Data were collected form 96 administrators of higher education in Alberta using both structured and unstructured interview methods. The study concluded that administrators in the Province generally considered marketing to be activities used in attracting resources. Only a few institutions in Alberta engaged in marketing research or used a comprehensive marketing plan. Shortage of funds was considered to be the major constraint on institutional marketing initiatives. Respondents predicted that more institutions would adopt marketing techniques in the near future.
Cloning of the mistletoe lectin gene and characterization of the recombinant A‐chain (1999)

Mistletoe lectin I (MLI) is the major active constituent of mistletoe extracts, which are widely used for adjuvant tumour therapy. The 66-kDa heterodimeric disulphide-linked glycoprotein is classified as type II ribosome-inactivating protein (RIP) due to the rRNA-cleaving enzyme activity of the A-subunit, also referred to as toxic entity. MLI and the close relative ricin both belong to the family of the two-chain plant type II RIP proteins. Isolation of the glycosylated proteins from plant material yield inhomogeneous material probably due to post-translational modifications. The aim of this study was to prepare pure and homogeneous protein as a prerequisite for structural and mechanistic studies in order to gain insight into the mode of action of this cytotoxic plant protein on tumour and immune cells. Of particular interest was to explain whether the differences in toxicity of ML and ricin are the result of variations of their enzymatic activities. By investigating the sequence homologies between the active sites of different RIPs we were able to deduce a set of primers which were suitable for specific amplification of the mistletoe lectin gene. Applying this PCR strategy the full-length 1923 nucleotide DNA sequence coding for the prepro-protein was obtained showing the existence of a single intron-free gene. In order to elucidate the molecular basis for the observed differences in cytotoxicity within the family of RIP the enzymatic A-subunit was expressed in a heterologous system. Expression of the A-chain in E. coli BL21/pT7 resulted in production of insoluble inclusion bodies constituting 20-30% of total protein. Refolding led to a pure and homogeneous protein species with an apparent molecular mass of 27 kDa and a pI value of 6.4. The ribosome-inactivating activity of the unglycosylated recombinant A-chain (IC50 20.5 pM) protein was in the same range as that of the glycosylated plant-derived ML A-chain (IC50 3.7 pM), which was very similar to that of ricin A-chain (IC50 4.9 pM). Thus, the higher cytotoxicity of ricin cannot be accountable for differences in the enzymatic activities of the type II RIP A-chains.
Time-frequency analysis of the dispersion of Lamb modes (1999)

Accurate knowledge of the velocity dispersion of Lamb modes is important for ultrasonic nondestructive evaluation methods used in detecting and locating flaws in thin plates and in determining their elastic stiffness coefficients. Lamb mode dispersion is also important in the acoustic emission technique for accurately triangulating the location of emissions in thin plates. In this research, the ability to characterize Lamb mode dispersion through a time-frequency analysis (the pseudo-Wigner-Ville distribution) was demonstrated. A major advantage of time-frequency methods is the ability to analyze acoustic signals containing multiple propagation modes, which overlap and superimpose in the time domain signal. By combining time-frequency analysis with a broadband acoustic excitation source, the dispersion of multiple Lamb modes over a wide frequency range can be determined from as little as a single measurement. In addition, the technique provides a direct measurement of the group velocity dispersion. The technique was first demonstrated in the analysis of a simulated waveform in an aluminum plate in which the Lamb mode dispersion was well known. Portions of the dispersion curves of the A0, A1, S0, and S2 Lamb modes were obtained from this one waveform. The technique was also applied for the analysis of experimental waveforms from a unidirectional graphite/epoxy composite plate. Measurements were made both along and perpendicular to the fiber direction. In this case, the signals contained only the lowest order symmetric and antisymmetric modes. A least squares fit of the results from several source to detector distances was used. Theoretical dispersion curves were calculated and are shown to be in good agreement with experimental results.
Annealing of ultra‐oriented high density polyethylene extrudates (1983)

Abstract The annealing characteristics of highly‐oriented, high density polyethylene (HDPE) fibers extruded at 90°C to constant extrusion draw ratios (EDR) of 5.8 to 30 have been studied using small‐(SAXS) and wide‐angle (WAXD) x‐ray diffraction, differential scanning calorimetry (DSC), thermal shrinkage and tensile tests. The thermal stability in macroscopic properties, such as transparency, sample dimension, and tensile modulus, remarkably increases with the sample EDR. However, the folded chain crystals within microfibrils sensitively reorganize on annealing at ≥ 110°C, even when the macroscopic properties exhibit no significant changes at high EDR's. Although the EDR has a minor effect on the reorganizability of the fold chain crystals, it has a major influence on the SAXS intensity and the extended chain crystalline component detected by WAXD for both unannealed and annealed extrudates. This specific crystalline component has an improved thermal stability and enhances the thermal stability of macroscopic properties at higher EDR. The fibers extruded at 90°C in this study and those prepared at 134°C in a prior study, exhibit significantly different melting behavior after annealing and for long period vs . EDR relationships. These facts combined with the independent observations of the effect of annealing and extrusion temperatures on the consequent long period strongly suggest that annealing during extrusion plays an important role in determining the microstructure of extrudates, especially for extrusion near the ambient melting point of the polymer.
Collagen Cross-Linking (CCL) With Sequential Topography-Guided PRK (2007)

The significant clinical improvement and the apparent stability of more than a year after UVA CCL, and subsequent PRK compared with the untreated mate eye, seems to validate this treatment approach for KC. An adjusted nomogram may be considered in the ablation of cross-linked cornea tissue to avoid overcorrections.
Effect of Lepidium meyenii (Maca), a root with aphrodisiac and fertility-enhancing properties, on serum reproductive hormone levels in adult healthy men (2003)

Lepidium meyenii (Maca) is a Peruvian hypocotyl that grows exclusively between 4000 and 4500 m in the central Andes. Maca is traditionally employed in the Andean region for its supposed aphrodisiac and/or fertility-enhancing properties. This study was a 12-week double-blind, placebo-controlled, randomized, parallel trial in which active treatment with different doses of Maca Gelatinizada was compared with a placebo. The study aimed to test the hypothesis that Maca has no effect on serum reproductive hormone levels in apparently healthy men when administered in doses used for aphrodisiac and/or fertility-enhancing properties. Men aged between 21 and 56 Years received 1500 mg or 3000 mg Maca. Serum levels of luteinizing hormone, follicle-stimulating hormone, prolactin, 17-alpha hydroxyprogesterone, testosterone and 17-beta estradiol were measured before and at 2, 4, 8 and 12 weeks of treatment with placebo or Maca (1.5 g or 3.0 g per day). Data showed that compared with placebo Maca had no effect on any of the hormones studied nor did the hormones show any changes over time. Multiple regression analysis showed that serum testosterone levels were not affected by treatment with Maca at any of the times studied (P, not significant). In conclusion, treatment with Maca does not affect serum reproductive hormone levels.
A probabilistic approach for power system security assessment (2012)

Integration of wind power generation into the grid raises a need to re-consider current power system planning and operation approaches due to variable nature of the wind power. This paper presents a probabilistic approach in power system security assessment with significant wind power penetration within operational context taken into account the uncertainty of wind. An example using a modified IEEE 14-bus system is used to illustrate the advantages of the proposed probabilistic approach compared with the traditional deterministic approach. The results show that the probabilistic approach provides a better view on the system security leading to better operational decision-making.
MicroRNA Fingerprints Identify miR-150 as a Plasma Prognostic Marker in Patients with Sepsis (2009)

We propose that miR-150 levels in both leukocytes and plasma correlate with the aggressiveness of sepsis and can be used as a marker of early sepsis. Furthermore, we envision miR-150 restoration as a future therapeutic option in sepsis patients.
Automatic test generation from communicating extended finite state machine (CEFSM)-based models (2003)

We present a methodology based on communicating extended finite state machines (CEFSM) to generate tests automatically from system specifications. Unlike other model-based methods, it does not require the creation of any new models. Rather, it uses the existing available system models including both data and behavioral information. Our CEFSM-based test generation uses FSMs (finite state machines) to model behavior and events, their extension with variables to model data, and their interaction channels to model communication. Our method generates tests based on a combination of behavior, data, and communication specifications. Another important difference is that our method addresses branching coverage not only for data-related decision coverage, but also behavioral transition coverage. Sophisticated "priority" and "dominator" analysis is applied to generate efficient test cases to increase, as much as possible with as few tests as possible, the branching coverage of the system being tested.
Issues in Oral Nanoparticle Drug Carrier Uptake and Targeting (2004)

Some of the broader issues relating to the exploration of the use of nanoparticulate drug carriers by the oral route to achieve absorption of molecules which are poorly absorbed from the gastrointestinal tract are considered briefly here. These relate to both the pharmaceutical and biological characteristics of the carrier and carrier-gut interactions, the dynamic nature of such interactions, the varied modes of uptake, and the difficulties in targeting to the gut epithelium to encourage more efficient uptake of nanoparticles. These have the unhelpful habit of aggregating and flocculating hence increasing their effective size, when small size aids uptake and translocation. Post-absorption events can be equally hazardous and need further research. The question is asked whether or not it is wise load the gut lumen with molecules such as insulin even when protected in a carrier, and the suggestion is made that targets need to be rethought. The epithelium of the gut and the lymphoid tissue itself offers much scope for therapeutic interventions through nanoparticle delivery.
Projector Calibration using Arbitrary Planes and Calibrated Camera (2007)

In this paper, an easy calibration method for projector is proposed. The calibration handled in this paper is projective relation between 3D space and 2D pattern, and is not correction of trapezoid distortion in projected pattern. In projector-camera systems, especially for 3D measurement, such calibration is the basis of process. The projection from projector can be modeled as inverse projection of the pinhole camera, which is generally considered as perspective projection. In the existing systems, some special objects or devices are often used to calibrate projector, so that 3D-2D projection map can be measured for typical camera calibration methods. The proposed method utilizes projective geometry between camera and projector, so that it requires only pre-calibrated camera and a plane. It is easy to practice, easy to calculate, and reasonably accurate.
Tim3 binding to galectin-9 stimulates antimicrobial immunity (2010)

T cell immunoglobulin and mucin domain 3 (Tim3) is a negative regulatory molecule that inhibits effector T(H)1-type responses. Such inhibitory signals prevent unintended tissue inflammation, but can be detrimental if they lead to premature T cell exhaustion. Although the role of Tim3 in autoimmunity has been extensively studied, whether Tim3 regulates antimicrobial immunity has not been explored. Here, we show that Tim3 expressed on T(H)1 cells interacts with its ligand, galectin-9 (Gal9), which is expressed by Mycobacterium tuberculosis-infected macrophages to restrict intracellular bacterial growth. Tim3-Gal9 interaction leads to macrophage activation and stimulates bactericidal activity by inducing caspase-1-dependent IL-1β secretion. We propose that the T(H)1 cell surface molecule Tim3 has evolved to inhibit growth of intracellular pathogens via its ligand Gal9, which in turn inhibits expansion of effector T(H)1 cells to prevent further tissue inflammation.
The contribution of cyclooxygenase‐2 to endocannabinoid metabolism and action (2007)

The development of sensitive analytical methods for measurement of endocannabinoids, their metabolites, and related lipids, has underlined the complexity of the endocannabinoid system. A case can be made for an 'endocannabinoid soup' (akin to the inflammatory soup) whereby the net effect of a pathological state and/or a pharmacological intervention on this system is the result not only of changes in endocannabinoid levels but also of their metabolites and related compounds that affect their function. With respect to the metabolism of anandamide and 2-arachidonoylglycerol, the main hydrolytic enzymes involved are fatty acid amide hydrolase and monoacylglycerol lipase. However, other pathways can come into play when these are blocked. Cyclooxygenase-2 derived metabolites of anandamide and 2-arachidonoylglycerol have a number of properties, including effects upon cell viability, contraction of the cat iris sphincter (an effect mediated by a novel receptor), mobilization of calcium and modulation of synaptic transmission. Nonsteroidal anti-inflammatory agents, whose primary mode of action is the inhibition of cyclooxygenase, can also interact with the endocannabinoid system both in vitro and in vivo. Other enzymes, such as the lipoxygenase and cytochrome P450 oxidative enzymes, can also metabolize endocannabinoids and produce biologically active compounds. It is concluded that sensitive analytical methods, which allow for measurement of endocannabinoids and related lipids, should provide vital information as to the importance of these alternative metabolic pathways when the primary hydrolytic endocannabinoid metabolizing enzymes are inhibited.

Neuropsychiatric symptoms of Alzheimer's disease differ in Chinese and American patients (2002)

We found support for our hypothesis, in that Chinese subjects presented during a more severe stage of dementia than American subjects, but the delay in seeking care could not be correlated with significant differences in neuropsychiatric profiles of the demented subjects. Other barriers to dementia care warrant investigation.
