Design and Simulation of Elephant Intrusion Detection System (2016)

Due to the increase in the population, human settlement is extending to forest border areas, causing conflicts between elephants and humans, leading to loss of life and property. Hence, large scale monitoring is required for real-time detection and warning of elephant intrusion into human settlements. Existing solutions using seismic waves, image processing, etc. are costly solutions for large scale monitoring. The project aims at developing an affordable solution for large-scale monitoring and early warning of elephant intrusion. In this work, architecture for elephant intrusion detection using wireless sensor networks is proposed and also a low cost sensor system has been designed and developed after selecting the appropriate sensors for monitoring. After analysing the existing signal processing methods, the most suitable technique for real-time detection of elephants is chosen and simulated. A two level detection system using microphones and IR sensors is used for monitoring the scenario and sound data is sent using FM transceivers to a PC.
La valoración del suelo urbanizado sin aprovechamiento lucrativo y el ámbito espacial homogéneo (a propósito de la STS de 27 de enero de 2017) (2017)

espanolEn este trabajo se examina la sentencia del Tribunal Supremo de 27 de enero de 2017, que establece el significado y alcance del articulo 37.1.a), parrafo segundo, del Texto Refundido de la Ley del Suelo y Rehabilitacion Urbana de 2015. Dicho precepto contempla el supuesto en el que el planeamiento urbanistico no fija aprovechamiento lucrativo a un terreno en situacion de urbanizado, afectado por una operacion expropiatoria. En detalle, segun el Tribunal Supremo, el concepto de «ambito espacial homogeneo» no puede venir determinado por el planeamiento, siendo precisa una delimitacion geografica de caracteristicas homogeneas en cada caso concreto EnglishThis paper focuses on sentence pronounced recently by the Spanish Supreme Court dated on 27th January, 2017 concerning the meaning and scope of Land Act 2015, article 37.1.a), second paragraph. That provision covers the situation in which urban planning does not determine lucrative use of urban land affected by an expropriation. In detail, according to the Supreme Court, urban planning should not determine the concept of «homogeneous space sector». A geographical demarcation of homogenous characteristics is needed in every particular case
The value of feedback for LTE resource allocation (2014)

The LTE cellular network is designed for meeting the requirements of a broad range of applications in very dynamic conditions. This explains its great flexibility in resource allocation. In order to provide the mobile stations with the exact required services, the base station relies on feedback information reported by each mobile station. In this paper, several feedback reduction schemes are analysed and compared, for a broad range of LTE resource allocation schemes and deployment scenarios, by means of simulation and a quantitative cost model. It is concluded that feedback reduction should be adapted to the scenario, as function of users, resource allocation strategy or channel properties, and up to 139% gain in overall throughput can be obtained by doing so.
Investigation of the local structure in LiCo1-2yNiyMnyO2 (0.25{less than or equal to}y{less than or equal to}0.5) cathode materials for Li-ion batteries (2007)

Layered LiCo1-2yNiyMnyO2 materials were synthesized with high homogeneity and crystallinity using the wet-chemical method assisted by oxalic acid as polymeric agent. The long-range and local structural properties are investigated with experiments including X-ray diffraction, Fourier transform infrared, Raman scattering, and electron paramagnetic resonance spectroscopy. The evolution of the structure is discussed as a function of the cobalt content, which confers layer-like behavior on the framework. Studies of the lithium extraction from the host lattices are also reported.

Mutual Information in 3D Video (2007)

3D video, which is captured by multiple synchronized cameras and consists of a sequence of mesh models, is becoming a hot topic recently. Similarity measure between frames is a powerful tool in video analysis. In this paper, an effective similarity measure based on mutual information is proposed for 3D video. Only vertex positions in mesh models are utilized in our mutual information. The mutual information is calculated based on the distance field in volumetric models, which are converted from mesh models. Our experiments demonstrate the mutual information can reflect the motion of the object in 3D video very well as a similarity measure.

InteMon (2006)

Modern data centers have a large number of components that must be monitored, including servers, switches/routers, and environmental control systems. This paper describes InteMon, a prototype monitoring and mining system for data centers. It uses the SNMP protocol to monitor a new data center at Carnegie Mellon. It stores the monitoring data in a MySQL database, allowing visualization of the time-series data using a JSP web-based frontend interface for system administrators. What sets InteMon apart from other cluster monitoring systems is its ability to automatically analyze correlations in the monitoring data in real time and alert administrators of potential anomalies. It uses efficient, state of the art stream mining methods to report broken correlations among input streams. It also uses these methods to intelligently compress historical data and avoid the need for administrators to configure threshold-based monitoring bands.
Configurable Integrated Photonics (2020)

Ion implantation into silicon results in a large refractive index change, which in turn can be tuned via thermal treatment to manipulate optical devices. In particular, devices such as Mach-Zehnder interferometers, directional couplers and ring resonators can be tuned, either to improve their performance, or as building blocks to “programme” them into a specific operating configuration. In contrast to several other programmable circuit techniques, this approach is non-volatile and therefore requires no additional power source to maintain the operating configuration once programmed. In paper the team discuss this approach to “programmable” or “configurable” photonic circuits in silicon photonics platforms.
Genetics of allozyme variation in Cuphea lanceolata Ait. (1989)

Genetic markers are needed for mating systems and breeding experiments in Cuphea lanceolata Ait.; however, none have been described in this species. Allozyme variation was analyzed among 14 F 2 populations assayed for aconitase (ACO), diaphorase (DIA), esterase (EST), fluorescent esterase transaminase (FEST), glutamine oxaloacetate transaminase (GOT), menadione reductase (MNR), phosphoglucomutase (PGM), phosphoglucose isomerase (PGI), and shikimate dehydrogenase (SKDH) enzyme activity. At least 23 loci were resolved in these enzyme systems: 6 monomorphic loci, 5 poorly resolved loci, and 12 clearly resolved polymorphic loci. Observed segregation ratios were generally not significantly different (P &gt; 0.05) from expected segregation ratios; however, segregation distortion was observed at Skdh-1 and Mnr-1 (Dia-1) in some F 2 populations. Skdh-1 and Pgm-2 and Est-1, Est-2, Fest-1, and Mnr-1 comprise putative linkage groups. Allozyme variation was observed between and within accessions. The expected average heterozygosity was 16.3%. There were one to eight polymorphic loci among the F 2 populations analyzed. There were an average of 2.05 alleles per locus. Several useful codominant markers were identified and a partial allozyme linkage map was constructed. Additional work is needed to revise and complete the map.Key words: Cuphea, isozymes, goodness of fit test statistics, lauric acid, capric acid.

In the optimization, the energy-delay product is minimized. The transistor is modeled by a neural network to increase the speed and the accuracy of the calculations.
Conjugate Wall Conduction-Fluid Natural Convection in a Three-Dimensional Inclined Enclosure (2012)

Laminar conjugate conduction-natural convection heat transfer in a 3-D inclined cubic enclosure comprised of finite thickness conductive walls and central cavity is numerically investigated. The dimensionless governing equations describing the convective flow and wall heat conduction are solved by the high accuracy multidomain pseudospectral method. Computations are performed for different Rayleigh numbers (103 ≤ Ra* ≤ 106), thermal conductivity ratios (1 ≤ k ≤ 100), dimensionless wall thickness (0 ≤ s ≤ 0.25), and enclosure inclinations (−30° ≤ α 1 ≤ 30°, 0° ≤ α 2 ≤ 45°). The effects of the above controlling parameters on the heat transfer performances of the enclosure system are investigated in detail, with emphases on the variations of wall conduction and fluid convection heat transfer, and the interactive heat transfer conditions between solid walls and fluid in the central cavity. Numerical results reveal that the existence of enclosure walls reduces the temperature gradient across the cavity and alters the temperature distribution within the solid walls; thus, the fluid convection is complexly determined by the combined effects of k and s, and is greatly affected by enclosure inclinations at high Rayleigh numbers. Moreover, the temperature distributions and solid-fluid interactive heat transfer conditions are provided for further interpretation and demonstration of the effects of the solid walls.

Can motion compensated reconstruction improve 'best phase' reconstruction in Cardiac CT? (2013)

Based on a phantom study with a realistic coronary vessel phantom, we investigated if motion compensated cardiac CT reconstruction can improve best phase image quality with respect to motion artifacts and patency of coronary vessel lumen. Basically, tracking based methods (with and without improvement of temporal resolution) deriving the motion fields by a registration-like procedure are compared to optimization based methods optimizing objective functions while minimizing artifact levels (e.g. Motion Artifact Metric Optimization (MAM) Reconstruction). Using the MAM technique, the motion field is iteratively calculated with a steepest descent update equation minimizing a motion artifact metric. We evaluated patency of the vessel lumen, the normalized cross correlation (NCC) of the respective reconstruction data with the ground truth data and a best phase improvement index correlating the motion compensated reconstruction data to the non-compensated FDK-based reconstruction data. It will be shown that the MAM technique is superior to the tracking methods. The latter proved to be more or less susceptible to template matching and, or erroneous template size. The value of MAM is also demonstrated evaluating clinical data. In particular it is beneficial for patients with high heart rates as well as for dose optimized scan protocols because it does not need over-radiation.

CYP716A Subfamily Members are Multifunctional Oxidases in Triterpenoid Biosynthesis (2011)

Triterpenoids are a diverse group of secondary metabolites that are associated with a variety of biological activities. Oleanolic acid, ursolic acid and betulinic acid are common triterpenoids in plants with diverse biological activities, including antifungal, antibacterial, anti-human immunodeficiency virus (HIV) and/or antitumor activities. In the present study, using the gene co-expression analysis tool of Medicago truncatula, we found a strong correlation between CYP716A12 and β-amyrin synthase (bAS), which encodes the enzyme responsible for the initial cyclization of 2,3-oxidosqualene to β-amyrin (the basic structural backbone of most triterpenoid saponins). Through an in vitro assay, we identified CYP716A12 as a β-amyrin 28-oxidase able to modify β-amyrin to oleanolic acid (through erythrodiol and, possibly, oleanolic aldehyde). We also confirmed its activity in vivo, by expressing CYP716A12 in transgenic yeast that endogenously produce β-amyrin. In addition, CYP716A12 was evaluated for its potential α-amyrin- and lupeol-oxidizing activities. Interestingly, CYP716A12 was able to generate ursolic acid (through uvaol and, possibly, ursolic aldehyde) and betulinic acid (through betulin). Hence, CYP716A12 was characterized as a multifunctional enzyme with β-amyrin 28-oxidase, α-amyrin 28-oxidase and lupeol 28-oxidase activities. We also identified homologs of CYP716A12 in grape (CYP716A15 and CYP716A17) that are involved in triterpenoid biosynthesis, which indicates the highly conserved functionality of the CYP716A subfamily among plants. These findings will be useful in the heterologous production of pharmacologically and industrially important triterpenoids, including oleanolic acid, ursolic acid and betulinic acid.
A Meta-Learning Approach to Predicting Performance and Data Requirements (2023)

We propose an approach to estimate the number of samples required for a model to reach a target performance. We find that the power law, the de facto principle to estimate model performance, leads to large error when using a small dataset (e.g., 5 samples per class) for extrapolation. This is because the log-performance error against the log-dataset size follows a nonlinear progression in the few-shot regime followed by a linear progression in the high-shot regime. We introduce a novel piecewise power law (PPL) that handles the two data regimes differently. To estimate the parameters of the PPL, we introduce a random forest regressor trained via meta learning that generalizes across classification/detection tasks, ResNet/ViT based architectures, and random/pre-trained initializations. The PPL improves the performance estimation on average by 37% across 16 classification and 33% across 10 detection datasets, compared to the power law. We further extend the PPL to provide a confidence bound and use it to limit the prediction horizon that reduces over-estimation of data by 76% on classification and 91% on detection datasets.

Cutaneous rash as a surrogate marker of time to tumor progression (TTP) with erlotinib in previously treated advanced non- small cell lung cancer (NSCLC) (2008)

19125 Background: Inhibition of the EGFR pathway has become an established strategy in NSCLC patients (pts) treatment. The aim of this study is to assess the value of predictive clinical variables associated with outcome in advanced NSCLC pts treated with erlotinib. Methods: Pts (n = 62) from a phase II trial with advanced NSCLC were treated with erlotinib (150 mg/day) upon chemotherapy (CT) progression. Pts characteristics were: performance status (PS), 0–1, 100%; median age, 58 years; males, 73%; adenocarcinoma, 45%; smoking history, 83%. Cutaneos rash during erlotinib: grade 0, 22 pts (35%); grade 1, 20 pts (32%); grade 2, 16 pts (26%); grade 3, 4 pts (7%). Standard Kaplan-Meier methods were used to plot the TTP of members of each group. The relative contribution of the different potential correlates of prognosis was assessed by the Cox proportional hazards method. Results: Partial response was noted in 6 pts (9.6%) and stable disease in 16 (26%). The median TTP was 43 days (95% confidence interval 19–326 days). The predictive factors analyzed were rash (0–1 vs 2–3), smoking history (yes vs no), PS (0 vs 1), age (≤ 65 vs > 65), and histology (adenocarcinoma vs others). Pts who developed rash grade 2–3 had TTP of 92.5 days vs 41 days for those without rash or rash grade 1 (P = 0.04, log-rank test). Pts with and without smoking history had TTP of 42 days vs 116.5 days, respectively (P = 0.002, log-rank test). Female and male had TTP of 85 days vs 42 days, respectively (P = 0.085, log-rank test). Pts with adenocarcinoma and other histologies had TTP of 76 days vs 42 days, respectively (P = 0.98, log-rank test). In a simple correlation analysis, a significant association was found between rash (grades 0, 1, 2 and 3) and TTP (Spearman rank correlation coefficient; Rs 0.34, P = 0.006). The Cox model showed a significant impact of rash grade (grade 2–3 vs 0–1; hazard ratio (HR) = 0.72, P = 0.045) on TTP and smoking history (no vs yes; HR = 0.31, P = 0.025). Conclusions: The appearance of rash grade 2 or higher is associated with improved TTP with erlotinib for advanced NSCLC pts previously treated with CT. In addition, a significant positive correlation has been found between rash grade and TTP.

Cryo-tomography tilt-series alignment with consideration of the beam-induced sample motion (2018)

Recent evidence suggests that the beam-induced motion of the sample during tilt-series acquisition is a major resolution-limiting factor in electron cryo-tomography (cryoET). It causes suboptimal tilt-series alignment and thus deterioration of the reconstruction quality. Here we present a novel approach to tilt-series alignment and tomographic reconstruction that considers the beam-induced sample motion through the tilt-series. It extends the standard fiducial-based alignment approach in cryoET by introducing quadratic polynomials to model the sample motion. The model can be used during reconstruction to yield a motion-compensated tomogram. We evaluated our method on various datasets with different sample sizes. The results demonstrate that our method could be a useful tool to improve the quality of tomograms and the resolution in cryoET.
Identification of Mammalian Vps24p as an Effector of Phosphatidylinositol 3,5-Bisphosphate-dependent Endosome Compartmentalization (2003)

Phosphatidylinositol 3,5-bisphosphate is a membrane lipid found in all eukaryotes so far studied but downstream effector proteins of this lipid have yet to be identified. Here we report the use of cDNA phage libraries in conjunction with synthetic biotinylated derivatives of phosphatidylinositol 3,5-bisphosphate in the identification of a mammalian phosphatidylinositol 3,5-bisphosphate-binding protein, mVps24p. This protein is orthologous to the Saccharomyces cerevisiae protein, Vps24p, a class-E vacuolar protein-sorting protein. Using in vitro liposome binding and competition assays, we demonstrate that mVps24p selectively binds to phosphatidylinositol 3,5-bisphosphate and phosphatidylinositol 3,4-bisphosphate in preference to other phosphoinositides tested. When expressed in cultured mammalian cells, full-length mVps24p is cytosolic. However, when cells expressing the full-length mVps24p are co-transfected with a mutated form of mVps4p (which is defective in ATP hydrolysis), or when a N-terminal construct of mVps24p is expressed, the class-E cellular phenotype with swollen vacuoles is induced and mVps24p is membrane-associated. Furthermore, the accumulation of the N-terminal mVps24p construct on the swollen endosomal membranes is abrogated when phosphatidylinositol 3,5-bisphosphate synthesis is blocked with wortmannin. These data provide the first direct link between phosphatidylinositol 3,5-bisphosphate and the protein machinery involved in the production of the class-E cellular phenotype. We hypothesize that accumulation of Vps24 on membranes occurs when membrane association (dependent on interaction of phosphatidylinositol 3,5-bisphosphate with the N-terminal domain of the protein) is uncoupled from membrane disassociation (driven by Vps4p).
Microresonator Frequency Comb Based High-Speed Transmission of Intensity\n Modulated Direct Detection Data (2021)

Globally, the long-haul transmission of ultra-high bandwidth data is enabled\nthrough coherent communications. Driven by the rapid pace of growth in\ninterconnectivity over the last decade, long-haul data transmission has reached\ncapacities on the order of tens to hundreds of terabits per second, over fiber\nreaches which may span thousands of kilometers. Data center communications\nhowever operate in a different regime, featuring shorter reaches and\ncharacterized as being more cost and power sensitive. While integrated\nmicroresonator frequency combs are poised to revolutionize light sources used\nfor high-speed data transmission over fiber, their use has been limited to\ncoherent detection schemes. In this paper, we demonstrate the use of\nmicroresonator frequency combs pumped with a single laser for the transmission\nof high-speed data, importantly using direct detection schemes. We achieve 120\nGb/s and 240 Gb/s aggregate data transmission for 30 Gb/s non-return-to-zero\n(NRZ) and 60 Gb/s pulse modulation amplitude 4 (PAM4) modulation formats\nrespectively over 2 km of optical fiber, exceeding the reach, single lane data\nrate, and aggregate data rates specified in Parallel Single Mode 4 (PSM4) and\nCourse Wavelength Division Multiplex 4 (CWDM4) multi-source agreements.\nRemarkably, we achieve an extremely low power penalty of 0.1 dB compared to\nback-to-back characterization. The results firmly cement CMOS-compatible\nmicro-resonator frequency combs based high-speed data transmission as a viable\ntechnology for the cost and power sensitive data center transceiver industry.\n
Reduced interface reaction during the epitaxial Fe growth on InAs for high efficiency spin injection (2004)

We have investigated Fe/InAs interfaces for two different growth temperatures of Fe and the effect on the spin injection properties through an Fe/InAs junction. Secondary ion mass spectroscopy and transmission electron microscopy studies of the Fe/InAs interfaces revealed that Fe films grown at 175 °C clearly suffer from increased reaction and out-diffusion of semiconductor constituents compared to those grown at 23 °C. The lower temperature samples showed an increased degree of spin polarization of 18%–20% which translates to 36%–40% of spin injection efficiency assuming selection rules between heavy and light holes in the p-type InAs substrate. It is close to the spin polarization of 40%–45% in an Fe spin injector itself.
