A composite scalar hint from di-boson resonances?

We study the light scalar resonance sector of a composite Higgs model UV embedding based on the coset $SU(4)/Sp(4)$. Beyond the Higgs multiplet, the pseudo Nambu-Goldstone sector of this model contains Standard Model singlets which couple to the Standard Model gauge bosons through Wess-Zumino-Witten anomaly terms. They can thus be produced in gluon fusion and decay into either gluons or pairs of electroweak gauge bosons $WW$, $ZZ$, $Z\gamma$, or $\gamma\gamma$. In this letter we show that one of the pseudo Nambu-Goldstone boson states has appropriate couplings in order to explain a di-boson excess in the $WW$ channel whilst not being excluded by LHC run I bounds on the di-jet, $Z\gamma$ and $\gamma\gamma$ decay channels. A di-boson resonance production cross section of $\sim$ 10 fb at LHC run I is not a prediction of the model, but can be obtained if the confining gauge group is of high rank.Comment: 5 pages, 3 figures, 2 table

On Testing Persistent-Memory-Based Software

Leveraging Storage Class Memory (SCM) as a universal memory--i.e. as memory and storage at the same time--has deep implications on database architectures. It becomes possible to store a single copy of the data in SCM and directly operate on it at a fine granularity. However, exposing the whole database with direct access to the application dramatically increases the risk of data corruption. In this paper we propose a lightweight on-line testing framework that helps find and debug SCM-related errors that can occur upon software or power failures. Our testing framework simulates failures in critical code paths and achieves fast code coverage by leveraging call stack information to limit duplicate testing. It also partially covers the errors that might arise as a result of reordered memory operations. We show through an experimental evaluation that our testing framework is fast enough to be used with large software systems and discuss its use during the development of our in-house persistent SCM allocator

AN INNOVATIVE CYLINDRICAL MAGNETRON SPUTTERING SOURCE FOR THE DEPOSITION OF HIE-ISOLDE SUPERCONDUCTING Nb/Cu QWRs

In the framework of Eucard project, it has been carried out, in collaboration with CERN, the R&D on magnetron sputtering deposition on the HIE-ISOLDE cavity geometry, as an alternative method to deposit niobium thin films. In this research a new magnetron configuration source was tested at the National Institute of Nuclear Physics (INFN-LNL), in order to deposit a uniform niobium thin film onto copper superconducting Quarter Wave Resonator cavities. The methodology was divided in three. A first part, in which a test dummy cavity and a test cathode were used in order to deposit stainless steel onto copper quartz. The purpose of the use of steel has been finding the right parameters of sputtering and also to analyze the uniformity of the film. In this first phase it have been tested several magnetic confinements, which allowed the optimization of the deposition. In parallel it was performed the deposition of stainless steel onto copper strips, to realize the stripping test as a method to analyze the uniformity of the film. The second part was focused on the deposition of niobium thin film onto quartz samples placed along the resonator to improve the superconducting properties, specifically Residual Resistivity Ratio (RRR) and Critical Temperature (Tc); nevertheless other magnetic confinements were tested to maintain the uniformity of the coating. It was studied the influence on superconducting properties of two principal parameters of the sputtering process: the power and the substrate temperature. After setting the deposition parameters, a definitive magnetron confinement was used to deposit the real copper QWR. The RF performance was also measured after the design, construction and installation of a test cryostat. Finally, it was found the magnetic source to deposit a niobium thin film uniformly over QWR cavities. Increasing the substrate temperature and the sputtering power, the transition temperature of the niobium thin film was around 9,3K and it was obtained a maximum RRR of 61. Only 30 min were necessary to deposit the film with a uniformity of 2±1 μm along the cavity. SEM results allowed to analyze the microstructure of the niobium film. Bigger grains were founds on the inner conductor closer to the magnetron source. In addition a test cryostat was successfully built in order to measure the RF performance; the system can be useful to perform measurements at 4.2 and 1.8 K. Respect to the RF performance the first Nb/Cu cavity is under the specifications of CERN with a maximum Q value of 2e8 and an accelerating field of 2MV/m; however this first result is extremely important to start with the optimization phase. Some parameters will be changed in order to improve the performance and push the SRF community to use the magnetron sputtering technique as an economical method to deposit superconducting cavities in short times

A balanced complex chromosomal rearrangement (BCCR) in a family with reproductive failure

Balanced complex chromosomal rearrangements are very rare events in the human population. Translocations involving three or more chromosomes frequently lead to a severe reproductive impairment secondary to meiotic disturbance in males and to chromosomal imbalance in gametes of females. We report a new familial case of complex chromosome anomaly involving chromosomes 13, 14 and 22. Cytogenetic investigations showed a complex chromosomal chromosome rearrangement involving: (i) a Robertsonian translocation between chromosomes 13 and 14; and (ii) a reciprocal translocation between the long arms of chromosome 14 and the long arm of chromosome 22. The aetiology of the translocation was characterized by conventional fluorescence in‐situ hybridization (FISH) studies and routine R‐ and G‐banding (RTBG and GBTG) combined with α and β satellite centromeric FISH probes. Predicted configuration of the hexavalent at pachytene stage of meiosis was used to consider the modes of segregation; only two configurations resulted in a normal or balanced gamete karyotype. Reproductive management and genetic counselling are discusse

Aplicação integral da Lei nº 1060/1950, Lei da Assistência Judiciária, no que tange às pessoas jurídicas sem fins lucrativos

A problemática que consiste no cerne do presente trabalho advém do cerceamento ao direito de pleito ao benefício da justiça gratuita, instituído pela Lei nº 1.060/1950 – Lei da Assistência Judiciária -, originado pela edição da Súmula nº 481 do Superior Tribunal de Justiça, a qual instituiu a obrigatoriedade de comprovação de situação de miserabilidade pelas pessoas jurídicas sem finalidade lucrativa. Tal posicionamento será objeto de discussão tendo em vista não se coadunar com os princípios constitucionais informadores do instituto da “justiça gratuita”, quais sejam, a isonomia, inafastabilidade de jurisdição e acesso à justiça. Ainda no sentido de demonstrar a controvérsia de tal imposição ao entes sem animus lucrandi, analisar-se-á a estrutura destes sujeitos de direito, evidenciando que a finalidade primeira destes entidades é assistencial e, por esta razão, há um conjunto de políticas tributárias que desoneram as pessoas jurídicas sem fito lucrativo, para que estas despendam o máximo de verbas na consecução de seus fins sociais, restando a restrição promovida pela posição sumulada em franca dissonância com o sistema de imunidades e isenções legais próprio desses sujeitos. Por derradeiro, o estudo apresenta que o citado entendimento sumulado fundou-se no artigo 5º, LXXIV da Carta Magna de 1988; todavia, a despeito da base constitucional, a imposição da demonstração de insuficiência de recursos pelo pleiteante da justiça gratuita deve considerar os ditames da Lei da Assistência Judiciária, uma vez que o texto fundamental exige a comprovação de miserabilidade para outro instituto jurídico diverso da gratuidade de justiça, o da assistência jurídica gratuita. No sentido de sanar a controvérsia em voga, defende-se a premência do cancelamento da Súmula nº 481 do STJ ou alteração de seu conteúdo retirando a exigência de prova de condição de miserabilidade para as pessoas jurídicas obterem a concessão do beneplácito da justiça gratuita e, mediatamente, que se promova a alteração no texto da Lei nº 1.060/1950, de modo a instituir legalmente os requisitos necessários para o pleito de gratuidade de justiça pelas pessoas jurídicas sem fins lucrativos ser atendido pelo Poder Judiciário

Memory management techniques for large-scale persistent-main-memory systems

Storage Class Memory (SCM) is a novel class of memory technologies that promise to revolutionize database architectures. SCM is byte-addressable and exhibits latencies similar to those of DRAM, while being non-volatile. Hence, SCM could replace both main memory and storage, enabling a novel single-level database architecture without the traditional I/O bottleneck. Fail-safe persistent SCM allocation can be considered conditio sine qua non for enabling this novel architecture paradigm for database management systems. In this paper we present PAllocator, a fail-safe persistent SCM allocator whose design emphasizes high concurrency and capacity scalability. Contrary to previous works, PAllocator thoroughly addresses the important challenge of persistent memory fragmentation by implementing an efficient defragmentation algorithm. We show that PAllocator outperforms state-of-the-art persistent allocators by up to one order of magnitude, both in operation throughput and recovery time, and enables up to 2.39x higher operation throughput on a persistent B-Tree
