Caracterización de aspectos en la seguridad de la sexualidad en el anciano (2012)

Se realizo un estudio descriptivo, transversal y prospectivo con el objetivo de caracterizar aspectos en la seguridad de la sexualidad en ancianos pertenecientes a dos Consultorios Medicos del Policlinico Universitario Hermanos Cruz de Pinar del Rio en el periodo 2008-2009. El universo estuvo conformado por 142 ancianos y la muestra por 100, seleccionados al azar, con su consentimiento. Para la obtencion y procesamiento de la informacion creo una base de datos. Se aplico una encuesta con preguntas cerradas y semiabiertas. Se obtuvo como resultado que la mayor frecuencia de los ancianos estuvo en el grupo de edades entre 70 y 74 anos con predominio del sexo masculino. La mayoria de los ancianos mantuvo relaciones sexuales de forma ocasional, y la ruptura de pareja despues del divorcio o la viudez fue ocasionada por desacuerdo de los familiares en mas de la mitad de ellos. Un gran porcentaje convivia con sus familiares constituyendo un obstaculo frecuente en la busqueda y mantenimiento de una nueva pareja despues de los 60 anos. La convivencia familiar influyo negativamente en el mantenimiento y la privacidad de la pareja lo que afecta la seguridad del anciano; se corroboro la existen de mitos y estereotipos que frecuentemente influyen de forma negativa en la practica sexual del adulto mayor, y la mayoria evita hablar de sexualidad con otras personas.
Recent progress on GaN-based superluminescent light-emitting diodes in the visible range (2018)

Superluminescent light emitting diodes (SLEDs) have beam-like optical output similar to laser diodes (LDs) while offering a broader emission wavelength spectrum. They represent, therefore, an interesting alternative to conventional LDs for applications where a short coherence length or low speckle noise are required. Visible SLEDs emitting in the red, blue, and green are ideal candidates for the manufacturing of speckle-free light sources in portable or wearable compact projection systems. In this paper, we review the current status of EXALOS’ GaN-based SLED technology in the violet-blue spectral range and report on our recent progress in terms of performance for devices with 440-460 nm emission. Furthermore, we discuss the challenges in achieving light output at even longer wavelengths. As a matter of fact, lower refractive index contrast between the waveguiding and cladding layers, decreased p-type doping efficiency when growing at low temperatures, low crystal quality and thermal stability of the active region have to be addressed and solved in order to achieve green emission. The epitaxial structures were grown by metalorganic vapor phase epitaxy (MOVPE) on c-plane freestanding GaN substrates. Growth was followed by standard fabrication of SLEDs with a ridge waveguide design. A record CW output power of 150 mW (at an operating current of 330 mA) and a wall-plug efficiency (WPE) of 8% have been obtained at an emission wavelength &gt;440 nm.

Kernel sparse representation for hyperspectral target detection (2012)

A nonlinear kernel-based classifier for hyperspectral target detection is proposed in this paper. The proposed approach relies on sparsely representing a test sample in terms of all the training samples in a high-dimensional feature space induced by a kernel function. Specifically, the feature representation of a test pixel is assumed to be compactly expressed as a sparse linear combination of few atoms from a training dictionary consisting of both background and target training samples in the same feature space. The sparse representation vector is obtained by decomposing the test pixel over the training dictionary via a kernelized greedy algorithm, which uses the kernel trick to avoid explicit evaluations of the data in the feature space. The class label is then determined by comparing the reconstruction accuracy with respect to the background and target sub-dictionaries using the recovered sparse vector. Designing the classifier in a high-dimensional feature subspace will implicitly exploit the higher-order structure (correlations) within the data which cannot be captured by a linear model. Therefore, by projecting the pixels into a kernel feature space and kernelizing the linear sparse representation model, the data separability between the background and target classes will be shown to be improved, leading to a more accurate detection performance. The effectiveness of the proposed kernel sparsity model for target detection is demonstrated by experimental results on real hyperspectral images.

Success factors of virtual communities from the perspective of members and operators: an empirical study (2004)

Virtual communities have been the focus of research for some time. However, while many studies provide recommendations on how to build, extend and manage virtual communities, few verify the success factors they consider essential for virtual communities. Conclusions made regarding basic preferences and distinct priorities of different stakeholders in virtual communities have not been empirically substantiated. This study uses an online survey of members and operators of virtual communities to evaluate success factors discussed in the literature. Incongruences between members and operators are identified and analysed. This research gains first empirically validated insights into success factors for establishing and managing virtual communities. The study results are summarised in ten hypotheses.
Polygenic risk score for Alzheimer’s disease in Caribbean Hispanics (2021)

Background Polygenic risk scores (PRS) provide an overall estimate of the individual’s genetic propensity to a trait by combining sparse information scattered across multiple genetic loci which often display small effect sizes. Most genetic studies are of European ancestry, ultimately limiting the use of PRS in other ethnicities. Here we constructed and validated a PRS for late-onset Alzheimer’s Disease (LOAD) in Caribbean Hispanics (CH). Method We employed genome-wide association summary statistics from 4,312 CH to construct an ancestry-specific PRS (“CH-PRS”) in an independent validation CH cohort (N=1,850). CH-PRS performance was evaluated using the area under the receiver operator characteristic (ROC) curves and logistic regression to evaluate strength of the association with LOAD and statistical significance. We sought to further replicate the CH-PRS in an independent CH dataset (Alzheimer’s Disease Research Center “ADC-CH”, N=200) and in a brain autopsy cohort (N=33). We also studied the CH-PRS performance in predicting conversion to LOAD in a subset of non-demented individuals at baseline with longitudinal data (N=600), employing a Cox regression model. Finally, we tested the effect of ethnicity on PRS performances by employing European (EUR) and African American (AA) ancestry studies as discovery datasets to construct alternative PRSs (“EUR-PRS”, “AA-PRS”) in our validation cohort. Result In the full model (LOAD ∼ CH-PRS + sex + age + APOE-ɛ4), the AUC reached 74.02% (OR=1.51 95%CI=1.36-1.68), raising to >75% in APOE-ɛ4 non-carriers. In the autopsy cohort, higher CH-PRS was significantly associated with pathological AD diagnosis (AD ∼ CH-PRS; AUC=72%; OR=2.35, 95%CI=1.0-5.52), and AUC=83% in the full model. In ADC-CH, the PRS showed significant association with LOAD (OR=1.61, 95%CI=1.19-2.17). CH-PRS significantly predicted conversion to LOAD over time (HR=1.96, CI=1.61-2.39). EUR-PRS and AA-PRS reached lower prediction accuracy (AUC=58% and 53%, respectively). Conclusion PRS is an effective strategy to delineate individual risk profiles as shown by our cross-sectional and longitudinal analyses as well as associations with well-established AD-hallmarks. Enriching diversity in genetic studies is indeed critical to provide a PRS tool that is effective in predicting LOAD risk across ethnic populations.
Ability of clinical laboratories to detect antimicrobial agent-resistant enterococci (1993)

To test the ability of clinical laboratories to detect antimicrobial resistance among enterococci, we sent four vancomycin-resistant enterococcal strains and one beta-lactamase-producing enterococcus to all 93 nongovernment, hospital-based clinical laboratories in New Jersey; 76 (82%) participated in the study. Each organism was tested by the laboratory's routine antimicrobial susceptibility testing method. The proportion of laboratories that correctly reported that an isolate was resistant to vancomycin varied according to the resistance level of the isolate: high-level resistance (MIC for Enterococcus faecium = 512 micrograms/ml), 96% of laboratories correct; moderate-level resistance (MIC for E. faecium = 64 micrograms/ml), 27% correct; low-level resistance (MIC for Enterococcus faecalis = 32 micrograms/ml), 16% correct; and intrinsic low-level resistance (MIC for Enterococcus gallinarum = 8 micrograms/ml), 74% correct. The beta-lactamase-producing E. faecalis isolate was identified as resistant to penicillin and ampicillin by 66 and 8% of laboratories, respectively, but only three laboratories recognized that it was a beta-lactamase producer. This survey suggests that many laboratories may fail to detect antimicrobial agent-resistant enterococci.
Reflection‐refraction effects on light distribution inside tubular photobioreactors (2017)

One of the main parameters affecting autotrophic algae cultures is photon absorption distribution inside the photobioreactor. This clearly depends on the geometry of both the radiation source and the photobioreactor, as well as on algae suspension optical properties. In this work the local volumetric rate of photon absorption LVRPA in a cross‐section of a horizontal‐pipe photobioreactor was investigated by means of simplified Monte Carlo simulations. In particular, the fate of a number of photons perpendicularly hitting the photobioreactor circular section was simulated in relation to different values of algae concentration. The model takes into account refraction/reflection phenomena at the air/photobioreactor‐wall interface. Simulation results show that radiation distribution inside the photobioreactor is quite strongly affected by reflection/refraction at the air‐reactor interface. In particular, dark zones (not revealed when neglecting reflection/refraction phenomena) are observed in conjunction with unexpected radiation intensification in other zones. These phenomena are bound to affect photobioreactor performance and should therefore be considered if effective photobioreactor models are sought.
X‐Ray Study of Rolled Single Crystals of Ti–48%Ni–2%FeAlloy. Part I: Texture Development and Mechanisms of PlasticDeformation (1998)

Rolled single crystals of the alloy Ti–48%Ni–2%Fe were studied by methods of X‐ray diffractometry using a PSD‐technique. Single crystals, consisting of the phase B2, were rolled in 11 initial orientations at 350°C with deformation degrees up to ~80%. Texture development in single crystals under rolling was analyzed to determine the acting mechanisms of plastic deformation. Three stable orientations of single crystals were found: {011}〈011〉 ,{111}〈011〉 and {111}〈112〉. It was shown on the basis of texture data, that Ti–Ni single crystals deform by means of combined action of slip in the systems {011}〈001〉 and twinning. For the first time, along with twinning in the known systems {114}〈221〉 , twinning in the systems {118}〈441〉 was revealed. A number of concrete cases was considered to refine the contributions of slip and twinning into reorientation of single crystals depending on their initial orientations as well as to ascertain the interrelation of different mechanisms.
Effect of Bacitracin Methylene Disalicylate on Turkey Poult Performance in the Presence and Absence of Stunting Syndrome (1994)

This study included a complete factorial arrangement of three dietary levels of bacitracin methylene disalicylate (BMD) (0, 50, and 200 g/ton) and two health conditions (none and stunting syndrome [SS]). One-day-old turkeys were dosed per os with tryptose phosphate broth or a supernatant derived from gastrointestinal tracts of poults with SS. Body weight, feed intake, feed efficiency, water intake, and hydration efficiency were determined at 5, 9, 13, 21, and 27 days of age. BMD at 200 g/ton in the feed significantly improved body weight (P < 0.005) of poults with SS at all ages, and it improved feed efficiency (P < 0.05) from 1 to 9 days of age. BMD at 50 and 200 g/ton improved hydration efficiency (P < 0.05) of poults with SS during the first 9 days of life.
Highly sensitive detection of C-reactive protein using a novel dissolution approach in a dye-doped silica nanoparticle-based fluorescence immunoassay (2017)

A novel dissolution approach was used to achieve enhanced sensitivity in a nanoparticle (NP) immunoassay for the detection of a cardiovascular disease marker, C-reactive protein (CRP).
Thermogenic Responses to High-Energy Phosphate Contents and/or Hindlimb Suspension in Rats. (1996)

Effects of chronic depletion of high-energy phosphate compounds by feeding beta-guanidinopropionic acid (beta-GPA) with or without hindlimb suspension (HS) on body temperature were studied in rats. Lower rectal and skin temperatures were observed in rats after 10 d of HS. Suspension-related enlargement of the interscapular brown adipose tissue (BAT), associated with adrenal hypertrophy, was seen. Feeding beta-GPA also caused a hypothermia and BAT enlargement. It is suggested that the hypothermic response to HS may be due to decreased contractile activity and metabolic rate in skeletal muscles, associated with stress. It is also speculated that the changes in the thermogenesis in rats fed beta-GPA might be related to a stimulated ATP synthesis with sacrificed heat production, but not associated with stress.
Characterization of an Intermediate in the Ammonia-Forming Reaction of Fe(DMeOPrPE)2N2 with Acid (DMeOPrPE = 1,2-[bis(dimethoxypropyl)phosphino]ethane) (2013)

The reactivity of Fe(DMeOPrPE)2N2 with water and acid was explored. (DMeOPrPE is the bidentate phosphine 1,2-[bis(dimethoxypropyl)phosphino]ethane.) The complex reacts with acid to form trans-[Fe(DMeOPrPE)2(N2)H](+) and small amounts of ammonia and hydrazine. When reacted with H2O, cis-Fe(DMeOPrPE)2(H)2 is formed. To increase the yields of ammonia and hydrazine, we investigated the effect of anion, solvent, and acid addition rate on the yields of ammonia. Of these parameters, only the properties of the anion (i.e., of the acid) had a significant impact on the yields of ammonia. The highest yields of NH3 occurred with the largest/least-coordinating anion (triflate). A short-lived purple intermediate (τ1/2 < 5 s at 23 °C) was observed in the reaction of Fe(DMeOPrPE)2N2 with triflic acid. Because the structure of this purple species could potentially provide valuable insights into the mechanism of ammonia formation, a method was developed for independently synthesizing and stabilizing the complex. Spectroscopic characterization of the purple species identified it as the paramagnetic [((DMeOPrPE)2Fe)2(μ-N2)](2+) complex (1). This purple dimer (1) exists in equilibrium with yellow, monomeric, paramagnetic [Fe(DMeOPrPE)2N2](+) (2). The role of 1 in the formation of hydrazine and ammonia was probed by reacting 1 with acid.
Severity of Airway Obstruction May Not Correlate With Weight Gain or Failure to Thrive in Infants With Robin Sequence: A Pilot Study (2021)

This pilot study questions the widely held and intuitively logical belief that poor weight gain and/or FTT should correlate with the severity of upper airway obstruction in patients with RS. Large prospective investigations should be initiated to better explore the authors' findings. Our results also underscore the importance of individualized treatment for these challenging patients.
Ambient Pain Monitoring in Older Adults with Dementia to Improve Pain Management in Long-Term Care Facilities (2020)

Painful conditions are prevalent in older adults, yet may go untreated, especially in people with severe dementia who often cannot verbally communicate their pain. Not addressing the pain can lead to the worsening of underlying conditions or lead to frustration and agitation. For older adults living in long-term care (LTC) facilities, timely assessment of pain remains a challenge. The main reasons for this are staff shortages at these facilities and/or insufficient expertise in cutting-edge pain assessment methods reliant on non-verbal cues. Ambient monitoring of non-verbal cues of pain, e.g. facial expressions, body movements, or vocalizations, is a promising avenue to improve pain management in LTC. Despite extensive existing research in computer vision algorithms for pain detection, the currently available techniques and models are not ready or directly applicable for use in LTC settings. Publicly available video datasets used for training and validating pain detection algorithms (e.g. the UNBC-McMaster Shoulder Pain Expression Archive Database and the BioVid Heat Pain Database) do not include older adults with dementia. Facial analysis models that are trained and validated on data from healthy and primarily young adults are known to under-perform, sometimes drastically, when tested on faces of older adults with dementia. As such, the performance of existing pain detection models on the dementia population remains to be validated. Furthermore, in existing datasets, participants are well-lit and face the camera; so the developed algorithm's performance may not transfer to a realistic ambient monitoring setting. In this work, we make three main contributions. First, we develop a fully-automated pain monitoring system (based on a convolutional neural network architecture) especially designed for and validated on a new dataset of over 162,000 video frames recorded unobtrusively from 95 older adults, of which 47 were community dwelling and cognitively healthy (age:~75.5~±~6.1), and 48 (age:~82.5~±~9.2) were individuals with severe dementia residing in LTC. Second, we introduce a data efficient pairwise training and inference method that calibrates to each individual face. Third, we introduce a contrastive training method and show that it significantly improves cross-dataset performance across UNBC-McMaster, cognitively healthy older adults, and older adults with dementia. We perform 5-fold (leave-subjects-out) cross-validation. Our algorithm achieves a Pearson correlation coefficient (PCC) of 0.48 for per-frame predictions of pain intensity and a PCC of 0.82 for predictions aggregated over 20 second windows for participants with dementia.
Online scheduled execution of quantum circuits protected by surface codes (2017)

Quantum circuits are the preferred formalism for expressing quantum information processing tasks. Quantum circuit design automation methods mostly use a waterfall approach and consider that high level circuit descriptions are hardware agnostic. This assumption has lead to a static circuit perspective: the number of quantum bits and quantum gates is determined before circuit execution and everything is considered reliable with zero probability of failure. Many different schemes for achieving reliable fault-tolerant quantum computation exist, with different schemes suitable for different architectures. A number of large experimental groups are developing architectures well suited to being protected by surface quantum error correcting codes. Such circuits could include unreliable logical elements, such as state distillation, whose failure can be determined only after their actual execution. Therefore, practical logical circuits, as envisaged by many groups, are likely to have a dynamic structure. This requires an online scheduling of their execution: one knows for sure what needs to be executed only after previous elements have finished executing. This work shows that scheduling shares similarities with place and route methods. The work also introduces the first online schedulers of quantum circuits protected by surface codes. The work also highlights scheduling efficiency by comparing the new methods with state of the art static scheduling of surface code protected fault-tolerant circuits.
Hot Corrosion of Preoxidized Ni by a Thin Fused Na2 SO 4 Film at 900°C (1990)

The hot corrosion of preoxidized 99% and 99.99% pure Ni covered with a thin film in a gas atmosphere was investigated at 900°C by an electrochemical method using a sodium sensor and an oxygen probe. The preoxidation conditions were varied in order to affect the sulfidation of Ni, which resulted in an increase in salt basicity and thereafter catastrophic corrosion. The basicity gradient generated across the thin salt film supported a self‐sustaining basic fluxing and reprecipitation of the protective scale.
PLINER: Isolating Lines of Floating-Point Code for Compiler-Induced Variability (2020)

Scientific applications are often impacted by numerical inconsistencies when using different compilers or when a compiler is used with different optimization levels; such inconsistencies hinder reproducibility and can be hard to diagnose. We present PLINER, a tool to automatically pinpoint code lines that trigger compiler-induced variability. PLINER uses a novel approach to enhance floating-point precision at different levels of code granularity, and performs a guided search to identify locations affected by numerical inconsistencies. We demonstrate PLINER on a real-world numerical inconsistency that required weeks to diagnose, which PLINER isolates in minutes. We also evaluate PLiNER on 100 synthetic programs, and the NAS Parallel Benchmarks (NPB). On the synthetic programs, PLiNER detects the affected lines of code 87% of the time while the stateof-the-art approach only detects the affected lines 6% of the time. Furthermore, PLINER successfully isolates all numerical inconsistencies found in the NPB.
