Real-Time Monitoring of Wind-Induced Vibration of High-Voltage Transmission Tower Using an Optical Fiber Sensing System (2019)

High-voltage transmission towers in coastal areas can be damaged by destructive hurricanes and strong seasonal winds. With real-time condition monitoring systems, severe and critical damage can be detected in the early stage, and appropriate solution taken. In this paper, we investigate the possibilities for real-time monitoring of wind-induced vibration of transmission towers, using an all-optical fiber sensing system. The optical sensing probe is made by splicing coaxially a thin-core fiber, with tilt fiber gratings inscribed into its core, to a lead-in single mode fiber. We experimentally demonstrated that our sensor can provide linear response higher than 97% over a range of 0.1-6.5 m/s <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Finally, in collaboration with a power grid company, we demonstrated the feasibility of the proposed all-optical fiber sensing system during field trials.

Unsupervised Domain-Specific Deblurring via Disentangled Representations (2019)

Image deblurring aims to restore the latent sharp images from the corresponding blurred ones. In this paper, we present an unsupervised method for domain-specific single-image deblurring based on disentangled representations. The disentanglement is achieved by splitting the content and blur features in a blurred image using content encoders and blur encoders. We enforce a KL divergence loss to regularize the distribution range of extracted blur attributes such that little content information is contained. Meanwhile, to handle the unpaired training data, a blurring branch and the cycle-consistency loss are added to guarantee that the content structures of the deblurred results match the original images. We also add an adversarial loss on deblurred results to generate visually realistic images and a perceptual loss to further mitigate the artifacts. We perform extensive experiments on the tasks of face and text deblurring using both synthetic datasets and real images, and achieve improved results compared to recent state-of-the-art deblurring methods.
Modeling Molecular Mechanisms of Binding of the Anaphylatoxin C5a to the C5a Receptor (2008)

This study presents the 3D model of the complex between the anaphylatoxin C5a and its specific receptor, C5aR. This is the first 3D model of a G-protein-coupled receptor (GPCR) complex with a peptide ligand deduced by a molecular modeling procedure analyzing various conformational possibilities of the extracellular loops and the N-terminal segment of the GPCR. The modeling results indicated two very different ways of interacting between C5a and C5aR at the two interaction sites suggested earlier based on the data of site-directed mutagenesis. Specifically, C5a and C5aR can be involved in "mutual-induced fit", where the interface between the molecules is determined by both the receptor and the ligand. The rigid core of the C5a ligand selects the proper conformations of the highly flexible N-terminal segment of C5aR (the first interaction site). At the same time, the binding conformation of the flexible C-terminal fragment of C5a is selected by well-defined interactions with the TM region of the C5aR receptor (the second interaction site). The proposed 3D model of C5a/C5aR complex was built without direct use of structural constraints derived from site-directed mutagenesis reserving those data for validation of the model. The available data of site-directed mutagenesis of C5a and C5aR were successfully rationalized with the help of the model. Also, the modeling results predicted that the full-length C5a and C5a-des74 metabolite would have different binding modes with C5aR. Modeling approaches employed in this study are readily applicable for studies of molecular mechanisms of binding of other polypeptide ligands to their specific GPCRs.
Field sampling and field reconstruction: A new perspective (2010)

[1] We address the problem of extracting the maximum amount of information on an electromagnetic field over a domain DO from field sample measurements on a domain DI, with a priori information on the source (or scatterer). The problem is faced in two steps. In the first one, the source reconstruction is dealt with by taking into account the available a priori information and the optimal probe positioning is determined as that optimizing the singular value dynamics of the involved linear radiation operator. The second step consists of reconstructing the field on DO as that radiated by the retrieved source. An extensive numerical analysis highlights the performance of the approach.

AnEscherichia coliprotein with homology to the H-protein of the glycine cleavage enzyme complex from pea and chicken liver (1991)

The nucleotide sequence of an Escherichia coli gene which presumably encodes the H-protein of the glycine cleavage (GCV) enzyme complex is presented. The gene, designated gcvH, encodes a polypeptide of 128 amino acids with a calculated molecular weight of 13,665 daltons. The translation start site was determined by N-terminal amino acid sequence analysis of a gcvH-lacZ encoded fusion protein. The E. coli H-protein shows extensive homology with the H-proteins from the pea (Pisum sativum) and the chicken liver GCV enzyme complexes. 85 of 128 amino acid residues are identical or chemically similar between the E. coli and the pea H-proteins, and 74 of 128 amino acid residues are identical or chemically similar between the E. coli and the chicken liver H-proteins. All three proteins have identical amino acid sequences from residues 61-65. This sequence contains the lysyl residue involved in lipoic acid attachment in the chicken liver H-protein.
Cellulose-reinforced composites: From micro-to nanoscale (2010)

This paper present the most relevant advances in the fields of: i) cellulose fibres surface modification; ii) cellulose fibres-based composite materials; and iii) nanocomposites based on cellulose whiskers or starch plateletlike nanoparticles. The real breakthroughs achieved in the first topic concern the use of solvent-free grafting process (plasma) and the grafting of the matrix at the surface of cellulose fibres through isocyanate-mediated grafting or thanks to "click chemistry". Concerning the second topic, it is worth to mention that for some cellulose/matrix combination and in the presence of adequate aids or specific surface treatment, high performance composite materials could be obtained. Finally, nanocomposites allow using the semi-crystalline nature and hierarchical structure of lignocellulosic fibres and starch granules to more deeply achieve this goal profitably exploited by Mother Nature
On the test quality evaluation of current testing techniques (2005)

This paper presents a new defect level/yield loss framework to estimate test quality of current testing techniques. We use this framework to compare the traditional I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">DDQ</sub> single-threshold approach to alternative techniques such as current ratios and a new one based on multiple thresholds. Results show that the choice of a current testing technique (and the setting of thresholds) greatly depends on the defect level target. Results also reveal that the multiple-threshold technique offers the lowest yield loss
Evaluación del tiempo de referencia de II a III nivel de atención del servicio de pediatría en la unidad de servicios de salud de Bosa y el Hospital San Rafael de Fusagasugá y las variables que influyen en el período de Enero de 2015 a Diciembre de 2016 (2017)

The Reference and Counter-Reference System, is the set of processes, procedures and technical activities that allow an adequate provision of health services that ensure quality, accessibility, opportunity, continuity and integrity. Objective: To evaluate the reference time from II through III level of attention of the pediatric service in the center of health services located in Bosa and the San Rafael Hospital of Fusagasuga during the period between January of 2015 and December of 2016. Methods and Materials: A multicenter observational, descriptive and cross-section study was conducted to analyze the different variables that influence within the time of reference. Outcome and Conclusions: The remission time in both hospitals was carried out in a less time or equal to one day in most cases. It was observed that the variables of sex and age did not influence the time of remission, and that the new health system in the USS of Bosa did not remitted as many patients to the Subnetwork as it was expected, a relationship was evidenced between the time and service of destination, since patients were remitted in a shorter time due to the severity of their condition and that a high percentage of cancellation was secondary to a health betterment. Recommendations: Continue with this type of research to increase the bibliography regarding the subject and to elaborate more studies beyond the pediatric population. Establish a regulation to standardize a time of remission

Estrogenic Plants: to Prevent Neurodegeneration and Memory Loss and Other Symptoms in Women After Menopause (2021)

In mammals, sexual hormones such as estrogens play an essential role in maintaining brain homeostasis and function. Estrogen deficit in the brain induces many undesirable symptoms such as learning and memory impairment, sleep and mood disorders, hot flushes, and fatigue. These symptoms are frequent in women who reached menopausal age or have had ovariectomy and in men and women subjected to anti-estrogen therapy. Hormone replacement therapy alleviates menopause symptoms; however, it can increase cardiovascular and cancer diseases. In the search for therapeutic alternatives, medicinal plants and specific synthetic and natural molecules with estrogenic effects have attracted widespread attention between the public and the scientific community. Various plants have been used for centuries to alleviate menstrual and menopause symptoms, such as Cranberry, Ginger, Hops, Milk Thistle, Red clover, Salvia officinalis, Soy, Black cohosh, Turnera diffusa, Ushuva, and Vitex. This review aims to highlight current evidence about estrogenic medicinal plants and their pharmacological effects on cognitive deficits induced by estrogen deficiency during menopause and aging.
Atmospheric acoustic interferometer tomography of temperature and winds (2005)

A technique is described for multiple-path propagation time measurements in the surface layer of the atmosphere. This is based on solving simple bi-directional ray tracing equations on successively higher penetrating paths using propagation times for a short acoustic pulse. The scattering process from turbulence is shown to be capable of providing signals from which phase comparisons can be made and time-of-flight deduced. Simulations demonstrate that the method has potential for deriving continuous temperature and wind profiles.&#13;\nIn practice a multiple-beam interferometer can be used at each end of the path. Such an in-strument has been designed and first results will be given, together with future planned en-hancements.
Prediction of Impending Rupture in Aneurysms Using 4D-CTA: Histopathological Verification of a Real-Time Minimally Invasive Tool in Unruptured Aneurysms (2004)

The authors describe the use of a 4D-CT angiogram to predict impending rupture in intact aneurysms, as a real-time, less invasive imaging technique. Histopathological verification and immunostaining of the bleb site performed on the study population reveals the significant predictive value of this tool. The point of maximum amplitude of pulsation of the aneurysm wall in unison with the RR interval of the electrocardiogram determines the potential rupture point. This helps in prioritizing the intervention for unruptured aneurysm cases, provides an effective screening of the high-risk population, and aids preoperative planning of clip application.
Oral Macrocystis pyrifera Fucoidan Administration Exhibits Anti-Inflammatory and Antioxidant Properties and Improves DSS-Induced Colitis in C57BL/6J Mice (2022)

Inflammatory bowel disease (IBD) is a complex and multifactorial disorder characterised by relapsing and remitting inflammation of the intestinal tract. Oxidative stress (OS) is the result of an imbalance between production and accumulation of reactive oxygen species (ROS), which has been associated with inflammatory responses and implicated in the exacerbation of IBD. Fucoidan, a sulfated polysaccharide from brown seaweed, is a well-known anti-inflammatory agent and emerging evidence indicates that fucoidan extracts from <i>Macrocystis pyrifera</i> (MPF and DP-MPF) may also modulate oxidative stress. This study investigated the impact of fucoidan extracts, MPF and DP-MPF in a dextran sodium sulphate (DSS)-induced mouse model of acute colitis. 3% DSS was administered in C57BL/6J male mice over a period of 7 days, and MPF and DP-MPF were co-administered orally at a dose of 400 mg/kg body weight. Our results indicated that MPF and DP-MPF significantly prevented body weight loss, improved the disease activity index (DAI), restored colon lengths, reduced the wet colon weight, reduced spleen enlargement, and improved the overall histopathological score. Consistent with the reported anti-inflammatory functions, fucoidan extracts, MPF and DP-MPF significantly reduced the colonic levels of myeloperoxidase (MPO), nitric oxide (NO), malondialdehyde (MDA) and increased the levels of antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT). In addition, MPF and DP-MPF significantly inhibited levels of pro-inflammatory cytokines in colon-derived tissues. Collectively, our results indicate that MPF and DP-MPF exhibited anti-inflammatory and antioxidant effects representing a promising therapeutic strategy for the cure of IBD.
Low-Loss MESFET Frequency Quadrupler from 5 to 20 GHz (1991)

The design of a direct quadrupler of a 5 GHz input signal to 20 GHz, using a single 0.3 μm MESFET, is described. Aminimum conversion loss of 6.5 dB has been measured, including about 2 dB of insertion loss of the MIC output filter. Due to the isolation provided by the FET, the input and output matching circuits can be designed independently. No idler circuits for the 2nd and 3rd harmonics are required.
Thermal Hysteresis in Cholesteric Color Responses (1970)

Abstract The magnitude of the thermal hysteresis exhibited by cholesteric liquid crystals is mainly dependent upon the material composition of the system and the operating range.
Carboxypeptidase Digestion in the Presence of Detergents (1987)

The detergents, sodium dodecyl sulfate (SDS), lauryl glutamate (LG), and octyl-(polydisperse)oligooxyethylene (Octyl-POE), were tested as to their effects on the activities of carboxypeptidases A, B, and P. In general, Octyl-POE showed little inhibition and SDS showed the strongest inhibition. Carboxypeptidase B was only slightly inhibited by SDS. The inhibitory effect of SDS on these enzyme activities depended not on its concentration but on its absolute amount. For a constant amount of SDS, the activities of carboxypeptidases A and B remained almost constant with increasing reaction volume. Commercial carboxypeptidase B is usually contaminated by carboxypeptidase A. With the addition of SDS, almost only carboxypeptidase B activity was detected.

Brucella abortus 1119-3 O-chain polysaccharide to differentiate sera from B. abortus S-19-vaccinated and field-strain-infected cattle by agar gel immunodiffusion (1988)

Purified Brucella abortus 1119-3 and Brucella melitensis 16M lipopolysaccharide O-chain polysaccharides were not precipitated in agar gel immunodiffusion by any of 24 sera from vaccinated cattle but were precipitated by 18 of 24 sera from infected cattle. This difference can be used to differentiate sera of cattle vaccinated with B. abortus S-19 from sera of some field-strain-infected cattle.
Nonlinear Hybrid Automata Model of Excitable Cardiac Tissue (2018)

Implantable cardiac devices like pacemakers and defibrillators are life-saving medical devices. To verify their functionality, there is a need for heart models that can simulate interesting phenomena and are relatively computationally tractable. In this benchmark we implement a model of the electrical activity in excitable cardiac tissue as a network of nonlinear hybrid automata. The model has previously been shown to simulate fast arrhythmias. The hybrid automata are arranged in a square n-by-n grid and communicate via their voltages. Our Matlab implementation allows the user to specify any size of model n, thus rendering it ideal for benchmarking purposes since we can study tool efficiency as a function of size. We expect the model to be used to analyze parameter ranges and network connectivity that lead to dangerous heart conditions. It can also be connected to device models for device verification.
Clodronate treatment significantly depletes macrophages in chickens. (2014)

Macrophages function as phagocytes and antigen-presenting cells in the body. As has been demonstrated in mammals, administration of clodronate [dichloromethylene bisphosphonate (Cl2MBP)] encapsulated liposomes results in depletion of macrophages. Although this compound has been used in chickens, its effectiveness in depleting macrophages has yet to be fully determined. Here, we show that a single administration of clodronate liposomes to chickens results in a significant depletion of macrophages within the spleen and lungs of chickens up to 4 d post-treatment. This finding suggests that, in order to obtain depletion of macrophages in chickens for greater than 5 d, it is necessary to administer clodronate liposomes 4 d apart. The study also showed that 2 treatments of clodronate liposomes at 4-day intervals resulted in the depletion of macrophages for up to 10 d. The findings of the present study will encourage more precise studies to be done on the potential roles of macrophages in immune responses and in the pathogenesis of microbial infections in chickens.
Apoptosis in Transgenic Mice Expressing the P301L Mutated Form of Human Tau (2008)

The rTg4510 mouse is a tauopathy model, characterized by massive neurodegeneration in Alzheimer's disease (AD)-relevant cortical and limbic structures, deficits in spatial reference memory, and progression of neurofibrillary tangles (NFT). In this study, we examined the role of apoptosis in neuronal loss and associated tau pathology. The results showed that DNA fragmentation and caspase-3 activation are common in the hippocampus and frontal cortex of young rTg4510 mice. These changes were associated with cleavage of tau into smaller intermediate fragments, which persist with age. Interestingly, active caspase-3 was often co-localized with cleaved tau. In vitro, fibrillar Abeta(1-42) resulted in nuclear fragmentation, caspase activation, and caspase-3-induced cleavage of tau. Notably, incubation with the antiapoptotic molecule tauroursodeoxycholic acid abrogated apoptosis-mediated cleavage of tau in rat cortical neurons. In conclusion, caspase-3-cleaved intermediate tau species occurred early in rTg54510 brains and preceded cell loss in Abeta-exposed cultured neurons. These results suggest a potential role of apoptosis in neurodegeneration.
Permethrin Resistance Status and Associated Mechanisms inAedes albopictus(Diptera: Culicidae) From Chiapas, Mexico (2020)

There are major public health concerns regarding the spread of mosquito-borne diseases such as dengue, Zika, and chikungunya, which are mainly controlled by using insecticides against the vectors, Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse). Pyrethroids are the primary class of insecticides used for vector control, due to their rapid knockdown effect and low toxicity to vertebrates. Unfortunately, continued use of pyrethroids has led to widespread insecticide resistance in Ae. aegypti; however, we lack information for Ae. albopictus-a sympatric species in Chiapas since 2002. In this study, we evaluated the permethrin resistance status of Ae. albopictus collected from Mexico and Texas. We also selected for permethrin resistance in the laboratory and investigated the potential mechanisms conferring resistance in this species. Knockdown resistance mutations, specifically F1534C, in the voltage-gated sodium channel gene, and increased activity of detoxifying enzymes were evaluated. Low levels of permethrin resistance (<2.4-fold) were observed in our field populations of Ae. albopictus and the F1534C mutation was not detected in any of the sites. Low levels of resistance were also observed in the artificially selected strain. There was significantly higher cytochrome P450 activity in our permethrin-selected and nonselected strains from Mexico compared to the control strain. Our results suggest the Ae. albopictus sampled from 2016 are mostly susceptible to pyrethroids. These results contrast with the high levels of permethrin resistance (>58-fold) found in Ae. aegypti from the same sites in Mexico. This research indicates the importance of continued monitoring of Ae. albopictus populations to prevent resistance from developing in the future.
