LP-VIcode: a program to compute a suite of variational chaos indicators

An important point in analysing the dynamics of a given stellar or planetary system is the reliable identification of the chaotic or regular behaviour of its orbits. We introduce here the program LP-VIcode, a fully operational code which efficiently computes a suite of ten variational chaos indicators for dynamical systems in any number of dimensions. The user may choose to simultaneously compute any number of chaos indicators among the following: the Lyapunov Exponents, the Mean Exponential Growth factor of Nearby Orbits, the Slope Estimation of the largest Lyapunov Characteristic Exponent, the Smaller ALignment Index, the Generalized ALignment Index, the Fast Lyapunov Indicator, the Othogonal Fast Lyapunov Indicator, the dynamical Spectra of Stretching Numbers, the Spectral Distance, and the Relative Lyapunov Indicator. They are combined in an efficient way, allowing the sharing of differential equations whenever this is possible, and the individual stopping of their computation when any of them saturates.Comment: 26 pages, 9 black-and-white figures.

Metástasis musculares del adenocarcinoma renal

El carcinoma renal puede producir metástasis, siendo las más frecuentes en pulmón, hígado, esqueleto y encéfalo. Las metástasis aisladas en el músculo esquelético son muy raras, existiendo alrededor de veinte casos publicados en la literatura. Presentamos dos casos de metástasis de carcinoma renal, localizadas en el músculo esquelético. Es importante el diagnóstico diferencial de estas metástasis con los sarcomas de partes blandas, ya que su tratamiento y pronóstico son muy diferentes.The renal cell carcinoma can produce metastatic, the most common are in lung, liver, bones and encephalon. The isolated metastatic in muscle are unusual, there are only twenty cases published, most of them isolated cases. We present two cases of metastatic of renal cell carcinoma isolated in skeletal muscle. It is very important the differential diagnosis of this kind of lesions with soft tissue sarcomas because treatment and prognosis are very different

External optical self-injection stabilization of an InP generic foundry platform based passively mode-locked ring laser

Timing stabilization of a photonic integrated circuit extended cavity passively mode-locked semiconductor ring laser with four gain sections and two saturable absorbers in a symmetric ring geometry by optical self-injection is presented. The laser has been fabricated using an InP generic integration technology platform. Repetition rate tuning up to 5.5MHz and a timing jitter reduction by optical self-injection from 99 fs (solitary laser operation) to 20 fs is demonstrated. The experimental results are in excellent agreement with results obtained by a stochastic time domain model which yet had been solely applied to edge-emitting straight waveguide semiconductor lasers

Comparison of Monolithic Optical Frequency Comb Generators Based on Passively Mode-Locked Lasers for Continuous Wave mm-Wave and Sub-THz Generation

In this paper, two different Passive Mode-Locked Laser Diodes (PMLLD) structures, a Fabry-Perot cavity and a ring cavity laser are characterized and evaluated as monolithic Optical Frequency Comb Generators (OFCG) for CW sub-THz generation. An extensive characterization of the devices under study is carried out based on an automated measurement system that systematically evaluates the dynamic characteristics of the devices, focusing on the figures of merit that define the optimum performance of a pulsed laser source when considered as an OFCG. Sub-THz signals generated with both devices at 60 GHz and 90 GHz are presented and analyzed in terms of electrical linewidth to compare such components for mm-Wave and sub-THz photonic generation. This work offers a systematic comparison of PMLLD devices for OFCG operation and provides reference information of the performance of two different device topologies that can be used for the implementation of photonic integrated sub-THz CW generation.We acknowledge COBRA Research Institute, Eindhoven University of Technology, the Netherlands for the fabrication of the ring lasers within the joint European platform for InP-based components and circuits, JePPIX.Publicad

Observation of phase noise reduction in photonically synthesized sub-THz signals using a passively mode-locked laser diode and highly selective optical filtering

A Continuous Wave (CW) sub-THz photonic synthesis setup based on a single Passively Mode-Locked Laser Diode (PMLLD) acting as a monolithic Optical Frequency Comb Generator (OFCG) and highly selective optical filtering has been implemented to evaluate the phase noise performance of the generated sub-THz signals. The analysis of the synthesized sub-THz signals up to 120 GHz gives as a result an effective reduction of the electrical linewidth when compared to direct harmonic generation that begins at 50 GHz and becomes greater as the frequency increases. The phase noise reduction offered by the setup, along with its integration potential, cost and bandwidth, make it a promising candidate to the development of an integrated and high performance low phase noise local oscillator in the sub-THz range.Work supported by the Spanish Ministry of Science and Technology through the project TEC2009-14525-C02-02 and by the European Commission FP7 iPHOS Project.

We propose a two-element mode-locked laser array operating at 1.56 µm. Optical pulses with 14.5-ps width, spectral bandwidth exceeding 7 nm, and RF line width of 260 kHz at 12.448 GHz are experimentally reported

Lipomas profundos

Se han revisado retrospectivamente 10 lipomas profundos localizados en los miembros. Todos los pacientes fueron intervenidos quirúrgicamente y el diagnóstico de certeza fue histopatológico. Siete de los casos eran lipomas intra o intermusculares y los restantes angiolipoma, hibernoma y fibrolipoma intraneural, respectivamente. El seguimiento medio postoperatorio fue de 48 meses (mínimo: 14, y máximo: 84). No ha habido recidiva en ningún caso.This article is a retrospective review of 10 deep lipomata localized in the limbs. In all the cases the treatment required surgery, and the diagnosis was made by histopathological analysis. Seven cases were intra or intermuscular lipomata, and the other three were angiolipoma, hibernoma and endoneural fibrolipoma. The average postoperative follow-up time was 48 months (14 min-84 max). None showed recurrence at review

Global Waste Management Outlook

The Global Waste Management Outlook, a collective effort of the United Nations Environment Programme and the International Waste Management Association, is a pioneering scientific global assessment on the state of waste management and a call for action to the international community. Prepared as a follow up to the Rio+20 Summit and as a response to UNEP Governing Council decision GC 27/12, the document establishes the rationale and the tools for taking a holistic approach towards waste management and recognizing waste and resource management as a significant contributor to sustainable development and climate change mitigation. To complement the Sustainable Development Goals of the Post-2015 Development Agenda, the Outlook sets forth Global Waste Management Goals and a Global Call to Action to achieve those goals
