PRODUCCIÓN DE BIOMASA DE NACEDERO (<i>Trichanthera gigantea</i>) EN DIFERENTES ESCENARIOS DE SOMBRA Y FRECUENCIAS DE CORTES, EN EL RANCHO EBENEZER. NIQUINOHOMO, MASAYA. 2005 (1970)

Con el objeto de contribuir al uso y manejo de nuevas especies forrajeras como alternativas para la alimentación animal, se realizó un estudio en el Rancho Agropecológico de Especies Menores Ebenezer (RAEME), ubicado a 4 km del Municipio de Niquinohomo, Departamento de Masaya. El cual está a una altitud de 384 msnm, con latitud norte de 11°52′25.18'' y longitud oeste de 86°05′14.89'', precipitación media anual es de 1,200 mm, con periodos lluviosos generalmente en los meses de Julio a Noviembre y con temperaturas mínimas de 22° C y máximas de 38° C, variando estas durante todo el año. Los suelos son de textura franco arcilloso y una profundidad efectiva de 40 cm. Se utilizaron plantaciones de nacedero (Trichanthera gigantea), bajo tres escenarios de sombra (4 hrs sol o penumbra, 8 hrs sol o sombra y más de 8 hrs sol), los que fueron establecidos hacia tres años y tenían espaciamientos de 1 m entre surcos y 1 m entre plantas. Además se realizaron cuatro frecuencias de corte (30, 60, 90 y 120 días). Se evaluaron las características morfoestructurales de nacedero, como: grosor, altura y número de tallos y rebrotes. Así como la producción de biomasa forrajera y el contenido de proteína. Al iniciar el estudio se hizo un corte de uniformidad. Posteriormente se seleccionaron cinco plantas sobre las cuales se evaluaron las características morfoestructurales, la producción de biomasa y el contenido de proteína. Se encontró que los mejores resultados de la morfoestructura de nacedero se presentan bajo condiciones de sombra o 8 hrs sol, seguido de la penumbra o 4 hrs sol, así mismo que la producción de biomasa fue mejor cuando los cortes se realizaron cada 120 días, siendo estas mayores cuando estaban en condiciones de sombra y penumbra (31 y 32 t ha-1 respectivamente). En cambio los contenidos de proteína fueron mayores cuando los intervalos de cortes eran menores (60 días), los cuales fluctuaron entre 20 y 23%. Encontrándose una relación inversa entre la edad de corte y producción de biomasa con respecto al contenido de proteína. Se concluye que el nacedero requiere de sombra para su buen comportamiento morfoestructural y productivo.DOI: 10.5377/calera.v10i14.25
Finding and Archiving the Internet Footprint (2009)

With the move to “cloud” computing, archivists face the increasingly difficult task of finding and preserving the works of an originator so that they may be readily used by future historians. This paper explores the range of information that an originator may have left on computers “out there on the Internet,” including works that are publicly identified with the originator; information that may have been stored using a pseudonym; anonymous blog postings; and private information stored on web-based services like Yahoo Calendar and Google Docs. Approaches are given for finding the content, including interviews, forensic analysis of the originator’s computer equipment, and social network analysis. We conclude with a brief discussion of legal and ethical issues.
Virtual reality head-tracking observation system for mobile robot (2014)

Previously, Hybrid-Routing Algorithm Model was proposed by the Structures, Pointing, and Control Engineering (SPACE) University Research Center <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> at California State University of Los Angeles (CSULA). The Hybrid-Routing Algorithm Model utilizes semi-autonomous control during robotic operations in unknown, remote, hazardous, or otherwise inaccessible terrains. In order to observe and monitor mobile robot's surroundings, an onboard virtual reality system has been designed and implemented. It operates by remotely following the commanded movement of the robotic mission operator's headset. The proposed design features the Inertial Measurement Unit (IMU) chip secured to the center of the iTV-goggles unit., which is worn by the robotic mission operator. Direction cosine matrix algorithm is used to update the body coordinates of the IMU chip to the global reference system. Euler angles are computed based on the angular orientation of the mission operator's headset and are transmitted to the mobile robot. The observation system contains multiple servo motors that rotate onboard camera based on the received pitch roll, and yaw information. The observation system transmits compressed visual information of robot's surroundings to the Host Computing Station. This video is rendered via iTV-goggles display to the mission operator.
Mapping interaction sites within the N-terminus of the calcitonin gene-related peptide receptor; the role of residues 23–60 of the calcitonin receptor-like receptor (2009)

The calcitonin receptor-like receptor (CLR) acts as a receptor for the calcitonin gene-related peptide (CGRP) but in order to recognize CGRP, it must form a complex with an accessory protein, receptor activity modifying protein 1 (RAMP1). Identifying the protein/protein and protein/ligand interfaces in this unusual complex would aid drug design. The role of the extreme N-terminus of CLR (Glu23-Ala60) was examined by an alanine scan and the results were interpreted with the help of a molecular model. The potency of CGRP at stimulating cAMP production was reduced at Leu41Ala, Gln45Ala, Cys48Ala and Tyr49Ala; furthermore, CGRP-induced receptor internalization at all of these receptors was also impaired. Ile32Ala, Gly35Ala and Thr37Ala all increased CGRP potency. CGRP specific binding was abolished at Leu41Ala, Ala44Leu, Cys48Ala and Tyr49Ala. There was significant impairment of cell surface expression of Gln45Ala, Cys48Ala and Tyr49Ala. Cys48 takes part in a highly conserved disulfide bond and is probably needed for correct folding of CLR. The model suggests that Gln45 and Tyr49 mediate their effects by interacting with RAMP1 whereas Leu41 and Ala44 are likely to be involved in binding CGRP. Ile32, Gly35 and Thr37 form a separate cluster of residues which modulate CGRP binding. The results from this study may be applicable to other family B GPCRs which can associate with RAMPs.
Using the DIFF Command for Natural Language Processing (2002)

Diff is a software program that detects differences between two data sets and is useful in natural language processing. This paper shows several examples of the application of diff. They include the detection of differences between two different datasets, extraction of rewriting rules, merging of two different datasets, and the optimal matching of two different data sets. Since diff comes with any standard UNIX system, it is readily available and very easy to use. Our studies showed that diff is a practical tool for research into natural language processing.
Towards an integrated approach to role engineering (2010)

Although role-based access control has become a preferred method to manage access control, it constitutes a significant effort to develop and maintain a role structure. Role engineering, the process of defining roles and assigning permissions and users to the roles, aims to define an accurate and complete set of roles using a variety of inputs. In this paper, we describe a unified approach to role engineering supporting a combination of different methodologies, and its partial implementation in the IBM Tivoli Role Modeling Assistant, a role engineering platform reflecting the dual importance of top-down and bottom-up data collection and analysis. Data, imported from multiple sources such as LDAP registries, human resource extracts in CSV format as well as from interviews with the organization's users and subject matter experts, can be browsed, filtered, and visualized. Roles can be created and edited manually or generated automatically from mining results.
Cutaneous Appearance of Porphyria by Ultraviolet Light (1956)

Physicians and investigators show increasing interest in porphyria with greater awareness and knowledge of the several clinical states making up this group. Students are busy making new classifications or revising older ones as new information unfolds. Combinations of symptoms and time of appearance go to separate the several varieties of porphyria, but all have the central theme of abnormal metabolism of porphyrins. The various clinical manifestations need corroboration by evidence of excretion of abnormal kinds and amounts of porphyrins. These are mostly uroporphyrin and products that precede it. Porphyria so commonly shows up with cutaneous symptoms as to be of interest and important to dermatologists. Some of these changes are vesiculation and blistering with consecutive lesions mild or severe and disabling. Pigmentation is common, as is hirsutism and alterations of hair growth patterns and sclerodermoid effects. Most of these alterations of the skin are at
Production and rheological properties of bioflocculant produced by Bacillus sp. DP-152 (1998)

The culture conditions for Bacillus sp. DP-152 in the flask were investigated for the production of polysaccharide flocculant, DP-152. The optimum pH and temperature for the flocculant production were 8.0 and 30°(Degree Sign)C, respectively. The favorable substrates for flocculant production were soluble starch and ammonium nitrate. The medium composition was optimized as follows: 30 g soluble starch, 0.75 g NH4NO3, 2.0 g K2HPO4, 0.1 g KH2PO4, 0.2 g MgSO4·7H2O, and 0.2 g MnSO4·4~5H2O in 11 of distilled water. Under this optimized condition, flocculating activity has been improved 4-fold compared with that of the basal medium. In the culture flask, the highest flocculating activity was obtained after 70 h of cultivation and the amount of bioflocculant DP-152 yielded was 12.4 g/1. The solution of bioflocculant DP-152 showed non-Newtonian characteristics. Bioflocculant DP-152 exhibited apparently higher viscosity at all concentrations compared to that of zooglan (from Zoogloea ramigera), and it was stable over a wide range of temperatures and pHs.
A reliable die attach method for high power semiconductor lasers and optical amplifiers (2002)

We have developed a reliable, high yield, void-free method for soldering high power semiconductor laser diodes epitaxy-side down. We have consistently obtained absolute thermal resistances as low at 1.5/spl deg/C/Watt and specific thermal resistances of 4/spl middot/10/sup -3/ K/spl middot/cm/sup 2//Watt on oxygen-free high conductivity (OFHC) copper heatsinks. This method has very wide process margins (75/spl deg/C), exhibits excellent repeatability (4%), and is suitable for laser die attach to diamond submounts.
Development of a ring PET insert for MRI (2013)

Our research group constructed a 12-module PET detection ring composed of Hamamatsu multi-pixel photon counter (MMPC) silicon photomultiplier (SiPM) detectors placed in a ring that is fully MRI compatible. This brain imager can be placed around the head of a patient (clinical setting) or subject (research setting) and allow for comfortable upright imaging. However, an alternative way to use this device, as enabled by the technology, is to indeed scan individuals in the supine position in conjuncture with current MRI systems. This PET prototype is able to image simultaneously as the MRI scan is occurring, thus maximizing co-registration and the accuracy of the assignment of metabolically active voxels to their anatomically correct counterparts as identified by the MR image. In this study, we first conducted some basic instrumentation tests to ensure the device was functioning properly outside of the MRI, and additionally scan some phantoms (Derenzo; Hoffman Brain) to assess the quality in which our brain imager is able to produce adequate images. After these initial studies, we conducted multiple different experiments inside a 3 Tesla MRI in order to see how the magnetic field would influence the operation of the PET imager and vice versa. Through simultaneous PET/MRI scanning of a Hoffman brain phantom filled with F <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">18</sup> radioactivity and water, it was shown that the quality of the MR image was largely unaffected by the PET imager. Furthermore, although the quality of PET imaging was affected by the RF pulsing, an acceptable PET image was nevertheless produced. As we discuss following the results, the success of this study shows that our brain imager is indeed MR compatible, and that next generation devices based on its concepts will continue to improve combined PET/MRI functionality. As two of the major advantages of this imager are the potential for low-dose scanning and its adaptability to any MRI scanner, this study suggests that PET/MRI brain imaging with low dose is in principle possible using an insert which could be adapted to any MRI scanner, using standard RF coils for that scanner.

Electronic band structure of wurtzite GaN under biaxial strain in the<i>M</i>plane investigated with photoreflectance spectroscopy (2002)

We investigate the modification of the electronic band structure in wurtzite GaN due to biaxial strain within the M plane using photoreflectance (PR) spectroscopy. The compressively strained M-plane GaN film is grown on $\ensuremath{\gamma}\ensuremath{-}{\mathrm{LiAlO}}_{2}$ (100). In the PR measurements, the electric-field vector (E) of the probe light is polarized parallel $(\ensuremath{\Vert})$ and perpendicular $(\ensuremath{\perp})$ to the c axis of GaN which lies in the growth plane. For E$\ensuremath{\perp}$c, the spectrum exhibits only a single resonant feature at lower energies, while for E$\ensuremath{\Vert}$c a different single resonant feature appears at higher energies. To identify these features, we calculate the strain dependence of the interband transition energies and the components of the oscillator strength using the $\mathbf{k}\ensuremath{\cdot}\mathbf{p}$ perturbation approach. Comparison with the calculations shows that the origin of the PR features and their significant in-plane polarization anisotropy is related to the influence of M-plane, biaxial compressive strain on the valence-band structure of GaN. We estimate the value of the deformation potential ${D}_{5}$ to be $\ensuremath{-}4.7 \mathrm{eV}.$
Pemirolast, a new oral nonbronchodilator drug for chronic asthma. (1992)

Pemirolast is a new oral, nonbronchodilator antiallergy medication that is being evaluated for the therapy of asthma. In this multicenter, double-blind, randomized study, 96 patients with mild asthma received pemirolast, 50 mg (n = 34); pemirolast, 25 mg (n = 31); or placebo (n = 31) BID for 6 weeks. Patients were evaluated weekly at the research centers; they maintained daily symptom diaries and measured peak expiratory flow rates twice a day. Methacholine challenge was performed at the start and end of the study. Results with pemirolast, 50 mg BID, showed statistically significant decrease in nocturnal symptoms (P = .02), in composite symptom scores (P = .02) and in bronchodilator use (P = .05) when compared with placebo. There were no statistically significant differences between treatments in pulmonary function tests or in methacholine challenge sensitivity. Pemirolast, 25 mg BID, did not differ from placebo. There were no significant adverse effects. Pemirolast, 50 mg BID, demonstrated sufficient antiasthma activity to warrant further studies in patients with more severe asthma and with higher doses.
Maximizing SIMD resource utilization in GPGPUs with SIMD lane permutation (2013)

Current GPUs maintain high programmability by abstracting the SIMD nature of the hardware as independent concurrent threads of control with hardware responsible for generating predicate masks to utilize the SIMD hardware for different flows of control. This dynamic masking leads to poor utilization of SIMD resources when the control of different threads in the same SIMD group diverges. Prior research suggests that SIMD groups be formed dynamically by compacting a large number of threads into groups, mitigating the impact of divergence. To maintain hardware efficiency, however, the alignment of a thread to a SIMD lane is fixed, limiting the potential for compaction. We observe that control frequently diverges in a manner that prevents compaction because of the way in which the fixed alignment of threads to lanes is done. This paper presents an in-depth analysis on the causes for ineffective compaction. An important observation is that in many cases, control diverges because of programmatic branches, which do not depend on input data. This behavior, when combined with the default mapping of threads to lanes, severely restricts compaction. We then propose SIMD lane permutation (SLP) as an optimization to expand the applicability of compaction in such cases of lane alignment. SLP seeks to rearrange how threads are mapped to lanes to allow even programmatic branches to be compacted effectively, improving SIMD utilization up to 34% accompanied by a maximum 25% performance boost.
Prediction of Road Traffic Congestion Based on Random Forest (2017)

With the process of urban modernization becoming faster and faster, there are more and more vehicles in the city, and the situation of urban traffic congestion is becoming more and more serious. In this paper, a model of traffic congestion prediction is constructed by using machine learning classification algorithm - random forest to construct traffic congestion state prediction model. The random forest algorithm has the characteristics of high robustness, high performance and high practicability. The weather conditions, time period, special conditions of road, road quality and holiday are used as model input variables to establish road traffic forecasting model. Finally, the results show that the traffic prediction model established by using the random forest classification algorithm has a prediction accuracy of 87.5%, and the generalization error is low, and it can be effectively predicted. Moreover, the calculation speed is fast, and it has stronger applicability to the prediction of congested condition.

Experimental Murine Endometriosis Induces DNA Methylation and Altered Gene Expression in Eutopic Endometrium1 (2008)

The eutopic endometrium in women with endometriosis demonstrates diminished endometrial receptivity and altered gene expression. It is unknown if the endometrium being defective gives rise to a predisposition toward endometriosis and infertility or, alternatively, if endometriosis causes the altered endometrial receptivity. Here we created experimental endometriosis in mice and examined the expression of several markers of endometrial receptivity in the eutopic endometrium. Methylation of Hoxa10 was also evaluated as a potential mechanism responsible for altered gene expression. Expression of each gene was measured using quantitative real-time RT-PCR at 14 wk after induction of endometriosis. Expression of Hoxa10 and Hoxa11, which are necessary for endometrial receptivity, were decreased in the endometriosis group. Insulin-like growth factor binding protein-1 (Igfbp1) mRNA was decreased in the endometriosis group. However, there was no change in Integrin beta3 (Itgb3) mRNA expression. Total progesterone receptor (Pgr-AB) was increased in the endometriosis group and the ratio of Pgr-B to Pgr-AB was increased, indicating a shift from Pgr-A to Pgr-B expression. Basic transcription element-binding protein-1 (Bteb1), official symbol and name Klf9, Kruppel-like factor 9, which functionally interacts with Pgr in endometrium, was also decreased in the endometriosis group. In addition, hypermethylation of Hoxa10 in the endometriosis group was shown by methylation-specific PCR and confirmed by bisulfite sequencing. These findings demonstrate that normal endometrium, when placed in an ectopic location to create experimental endometriosis, led to characteristic changes in gene expression in eutopic endometrium. These data suggest the existence of a signal conduction pathway from endometriosis that alters endometrial gene expression through altered Pgr signaling and epigenetic programming.
A framework for evaluating application of smart cards and related technology within the Department of Defense (1994)

The author presents a new framework for evaluating the evolutionary upgrade paths of card technologies Many functions which are now either not being done, or are being done manually, could be automated using card technologies. There is a revolution underway in card technologies, making them viable solutions to an expanding set of problems. The author examines these card technology initiatives, the shrinking defense budget, card selection issues, card authentication techniques, and revolutionary acquisition. Conclusions stress that card technology systems can be viewed as evolutionary upgrade paths that change over time. Simple cost benefit analysis does not capture the evolving nature of advancing technology Effective evaluations of evolutionary card systems must consider this temporal component, and a framework, such as the one presented in this thesis, is needed for comparing alternative card systems.
Positive Feedback Regulation between MMP-9 and VEGF in Human RPE Cells (2007)

There is a positive feedback regulation between MMP-9 and VEGF in RPE cells. The hypoxic expression of MMP-9 may stimulate the production and secretion of VEGF under pathologic conditions. Triamcinolone inhibits the positive feedback regulation between MMP-9 and VEGF under hypoxic conditions through inhibition of the gene expression of MMP-9 and the secretion of VEGF.
Digital Comics Image Indexing Based on Deep Learning (2018)

The digital comic book market is growing every year now, mixing digitized and digital-born comics. Digitized comics suffer from a limited automatic content understanding which restricts online content search and reading applications. This study shows how to combine state-of-the-art image analysis methods to encode and index images into an XML-like text file. Content description file can then be used to automatically split comic book images into sub-images corresponding to panels easily indexable with relevant information about their respective content. This allows advanced search in keywords said by specific comic characters, action and scene retrieval using natural language processing. We get down to panel, balloon, text, comic character and face detection using traditional approaches and breakthrough deep learning models, and also text recognition using LSTM model. Evaluations on a dataset composed of online library content are presented, and a new public dataset is also proposed.
Methodology for remanufacturing of industrial robotic manipulators using open control architecture (2013)

Currently, an increasing number of robotic manipulators are discarded on the factory floor, because they are classified as unserviceable equipment, while still being able to be re-used. This problem occurs due to the fact that robot manufacturers use fully closed architecture control to their hardware and software systems. Thus, there is no interchangeability between the control cabinets and the programming languages used to generate kinematics, which make the repairs, modifications and implementations to system more expensive, due to these processes being dependent of each manufacturer. Therefore this paper proposes a methodology for the implementation of remanufacturing industrial robotic manipulators. In this methodology electronic components and electromechanical robot original can be re-used and its control systems are adapted to new technologies, using a fully open control architecture. Thus, the hardware devices are interchangeable with other processes and the programming language is not proprietary and can be modified or replaced by another.
