Design Automation and Design Space Exploration for Quantum Computers

A major hurdle to the deployment of quantum linear systems algorithms and recent quantum simulation algorithms lies in the difficulty to find inexpensive reversible circuits for arithmetic using existing hand coded methods. Motivated by recent advances in reversible logic synthesis, we synthesize arithmetic circuits using classical design automation flows and tools. The combination of classical and reversible logic synthesis enables the automatic design of large components in reversible logic starting from well-known hardware description languages such as Verilog. As a prototype example for our approach we automatically generate high quality networks for the reciprocal $1/x$, which is necessary for quantum linear systems algorithms.Comment: 6 pages, 1 figure, in 2017 Design, Automation & Test in Europe Conference & Exhibition, DATE 2017, Lausanne, Switzerland, March 27-31, 201

Independent tuning of acoustic and mechanical properties of phantoms for biomedical applications of ultrasound

In this work the preparation of tissue mimicking materials (TMMs) with independently tunable acoustic and elastic properties is reported. Although a large number of hydrogel, synthetic polymer, polysaccharides or other natural based materials have been proposed and used for the realization of TMMs, both for diagnostic and therapeutic applications of ultrasounds, up to today, simulation of acoustic properties was often performed using solid particles, reducing dramatically the transparency and inevitably affecting the homogeneity and the elastic properties of the TMM. By means of concentrated salts solutions and different polysaccharides, an easy method to prepare these TMMs have been developed. This approach would lead to obtain homogenous TMMs with Young modulus ranging over 3 orders of magnitude, i.e. from 2 to 1500 kPa, with independently tunable attenuation properties. An accurate mechanical and acoustic characterization of these TMMs have been performed. Finally, by means of a preliminary trials on protein denaturation induced by a high focused ultrasound transducer in a transparent TMMs with different attenuation values, the mechanism underlying on the formation and propagation of lesion has been investigated. Obtained results suggest that this 'chemical' approach would strongly support in vitro investigations on the open issues related to diagnostic and therapeutic application of ultrasounds

La muerte de "Mono Jojoy" : prensa escrita y conflicto armado

A partir de un hecho específico -muerte de alias "Mono Jojoy" - se analizó la forma como los medios de comunicación en Colombia cubren el conflicto armado. Dos periódicos de circulación nacional fueron tenidos en cuenta para la investigación: El Espectador y El Tiempo. Un total de 122 piezas informativas, recolectadas en un periodo de un mes, fueron propicias para, por medio de una matriz de análisis, observar la calidad y valores periodísticos. Así pues, se pudieron observar fallas existentes en los estándares de calidad. Sin embargo, son falencias que se atribuyen, en cierta medida, al contexto socio político del país. Aunque, es válido aclarar que lo anterior no pretende justificar que esfuerzos adicionales por parte de los periodistas encargados de cubrir el hecho específico no fueran tendidos en cuenta para dar a las audiencias información de mayor calidadComunicador (a) SocialPregrad

9/11 Relief and Regranting Funds

This report provides an overview of the activities and beneficiaries of the funds and agencies involved in 9/11-related disaster relief and recovery, drawn from data compiled by the Foundation Center through September 2003. Reflecting differences in sources of information, the report offers two distinct and complementary views of the funds:Part I discusses findings from our 2003 survey of large and small relief funds and agencies. The survey provides a broad perspective on the activities and practices of 9/11-related charities and considers the impact of size and sponsor type on patterns of assistance, sources of support, and timetables for distributing aid. More importantly, it sheds light on some of the planning and operational constraints involved in the delivery of disaster relief and the creative responses and collaborative efforts required to overcome these difficulties and achieve results.Part II documents total contributions raised and distributed by 40 of the largest 9/11 relief and regranting funds. The analysis tracks the purposes and beneficiaries of nearly $2.2 billion distributed by these charities for relief and recovery efforts through September 2003, and projects distribution patterns for unspent funds

Hygrometric applications of microwave quasi-spherical resonators

In this work, triggered by the initial suggestion and the preliminary results obtained at the National Institute for Standards and Technology (NIST), we have explored the possible application of a microwave resonant cavity to realise a reference standard hygrometer. Particularly, we have measured the microwave resonance frequencies of a small volume (69 cm^3) triaxial elipsoidal cavity to determine the water vapor mole fraction x_w of H2O/N2 and H2O/air mixtures. The mixtures were prepared using the INRiM standard humidity generator for frost-point temperatures T_fp in the range between 241 K and 270 K and a commercial two-pressure humidity generator operated at dew-point temperature T_dp between 272 K and 291 K. Following these tests, we demonstrated the performance of the QSR operated as a condensation hygrometer. For this demonstration, a suitable experiment was prepared in cooperation with the National Physical Laboratory (NPL), which allowed to compare the performance of the QSR with that of a calibrated chilled-mirror hygrometer. Finally, with the aim of reducing the uncertainty currently associated to the literature values of the constants in the Debye equation, we have measured the dielectric constant of pure water vapour in the temperature range from 320 K to 470 K at pressures up to 1.7 MPa. As a whole, the results obtained in these experiments demonstrated the validity and satisfactory performance of the microwave technique for hygrometr

Giving in the Aftermath of 9/11: 2003 Update on the Foundation and Corporate Response

The unprecedented outpouring of charitable support that followed the September 11, 2001, terrorist attacks prompted the Foundation Center to launch a multiyear effort to track relief and recovery funding by foundations, corporations, and other institutional donors. Our goal early on was to document the philanthropic response as it was happening so that grantmakers and charities could better identify unmet needs, and to help the field respond to questions from the media, government officials, and the general public. Over the longer term, our goal is to provide a definitive record of the response that will help the philanthropic sector identify its successes and lessons learned, so that it can respond even more effectively to future disasters

Field Penetration in MRI-based Breast Models: a Numerical Investigation

The use of reliable computational tools is fundamental to investigate different aspects of microwave breast cancer imaging. From the development of high-definition and realistic numerical breast models, different coupling mechanisms and the reaction of different tissues to microwave signals can be characterized. In this paper, field penetration inside four numerical breast phantoms with varying adipose content is evaluated in the frequency range 0.5 - 10 GHz across sagittal cuts
