Coupled magnetic and elastic properties in LaPr(CaSr)MnO manganites

We investigate a series of manganese oxides, the La0.225Pr0.4(Ca1-xSrx)0.375MnO3 system. The x = 0 sample is a prototype compound for the study of phase separation in manganites, where ferromagnetic and charge ordered antiferromagnetic phases coexist. Replacing Ca2+ by Sr2+ gradually turns the system into a homogeneous ferromagnet. Our results show that the material structure plays a major role in the observed magnetic properties. On cooling, at temperatures below 100 K, a strong contraction of the lattice is followed by an increase in the magnetization. This is observed both through thermal expansion and magnetostriction measurements, providing distinct evidence of magneto-elastic coupling in these phase separated compounds

Surgery for pulmonary aspergiloma: curative?

Introduction.In lhe last few decades, there has been an increase in fungal diseases, especially in those caused by Aspergillus.The aim of this retrospective study was to confirm or ascertain whether surgical intervention to pulmonary aspergiloma can result in a cure or long term palliative treatment with improvement of quality of life. Methods and materiais. From 1989 to 2001, 23 patients with mean age of 44.1 years (18-69 years) were submitted to pulmonary surgery for excision of aspergilloma. Sixteen patients were mate (70%). The most frequent indication for surgery was haemoptysis in 16 patients (70%) followed by abundant sputum in 3 patients (3%). Four patients (17%) were asymptomatic. Old tuberculosis lesions (87%) or pulmonary abscesses (13%) were lhe basic conditions for lhe aspergilloma. Pre-operative evaluation of respiratory function showed a mean vital capacity of 69.8% (61-84% limits) and lhe mean Fevl was 66% (53-82% limits). Results. This group of patients were submitted to 18 lobectomies (82%), 2 bilobectomies (7%), 2 wedge resections and 1 pneumonectomy (4%). There was no operative mortality and lhe morbidity in lhe post-operative period was: persistent air leak in 7 patients (30%), post-operative bleeding in 2 patients (7%) and residual cavities in 2 patients (7%). The mean time of follow-up was 7.2 years (limits 1.5-14 years) and 3 deaths were registered. Two deaths were related to intestinal neoplasia and 1 related to lhe original disease, 5 years after surgery. All surviving patients referred good improvement of symptoms and quality of life. Conclusions. The resection of pulmonary aspergilloma could be performed with a low morbidity and mortality. The patients referred good improvement of symptoms and quality of life after surgery. Consequently, we suggest that surgical therapy is an option for both symptomatic and asymptomatic patient

Evaluation of cyclone geometry and its influence on performance parameters by computational fluid dynamics (CFD)

Cyclone models have been used without relevant modifications for more than a century. Most of the attention has been focused on finding new methods to improve performance parameters. Recently, some studies were conducted to improve equipment performance by evaluating geometric effects on projects. In this work, the effect of cyclone geometry was studied through the creation of a symmetrical inlet and a volute scroll outlet section in an experimental cyclone and comparison to an ordinary single tangential inlet. The study was performed for gas-solid flow, based on an experimental study available in the literature, where a conventional cyclone model was used. Numerical experiments were performed by using CFX 5.7.1. The axial and tangential velocity components were evaluated using RSM and LES turbulence models. Results showed that these new designs can improve the cyclone performance parameters significantly and very interesting details were found on cyclone fluid dynamics properties using RSM and LES.839

Reference priors for high energy physics

Bayesian inferences in high energy physics often use uniform prior distributions for parameters about which little or no information is available before data are collected. The resulting posterior distributions are therefore sensitive to the choice of parametrization for the problem and may even be improper if this choice is not carefully considered. Here we describe an extensively tested methodology, known as reference analysis, which allows one to construct parametrization-invariant priors that embody the notion of minimal informativeness in a mathematically well-defined sense. We apply this methodology to general cross section measurements and show that it yields sensible results. A recent measurement of the single top quark cross section illustrates the relevant techniques in a realistic situation

Vascular flora of Monte Sparviere (southern Italy, Pollino Massif)

Vascular Flora of Monte Sparviere (Southern Italy, Pollino Massif). A floristic survey of Monte Sparviere was carried out from 2012 to 2015, allowing us to record 377 specific and subspecific taxa, belonging to 229 genera and 64 families. The most represented families are Asteraceae (55 taxa), Poaceae (30), Fabaceae (28), Rosaceae (23) and Lamiaceae (19). Italian endemic species reach the 8.5% and no exotic species are recorded except three conifers used for reforestation. Biological spectrum shows a dominance of Hemicryptophytes, with a moderate percentage of Therophytes. The chorological analysis shows a dominance of species belonging to the Eurosibiric region, albeit Mediterranean region is also well represented. The ecological spectra are in agreement with climatic and geo-pedologic features, with variations mainly related to woody coverage and altitude. Finally, Potentilla pedata Willd. ex Hornem was confirmed for the flora of Basilicata; Dianthus sternbergii Capelli was excluded from the flora of Basilicata and Calabria whereas Dianthus hyssopifolius L. resulted new for both regions

Diaphragmmatic eventration: long-term follow-up and results of open-chest plicature

Objective: Diaphragmmatic eventration is a relatively uncommon entity with a simple surgical correction technique - plication of the diaphragm. This study aims to assess the clinical and ventilatory impact of this technique. Materials: From April 1988 to February 2007, we operated on 20 patients (12 men) with diaphragmmatic eventration using the postero-lateral approach and correction by radial plication. The mean age of the patients studied was 56.3+/-15.6 years (range: 13-74 years). A traumatic cause was identified in 13 patients; one patient had a congenital cause and the remainder were of idiopathic origin. Chronic obstructive pulmonary disease and arterial hypertension were present in one-half of the study group, while diabetes mellitus was present in three patients. Dyspnoea was the most common complaint in 75% of the patients, and thoracic pain was present in 25%. The mean forced expiratory volume in 1s (FEV(1)) and vital capacity (VC) were 66.2+/-15.3% and 70.4+/-16% of the predicted values, respectively. Results: There was no operative mortality. Apart from a patient with moderate/severe pain and another who had pneumonia, there were no other important perioperative complications. Average drainage time was 3.3+/-1.6 days (range: 2-7 days). Hospitalisation time was 6.2+/-1.6 days (5-10 days). Follow-up was complete, for a mean of 59.6+/-55.1 months (4-206 months). There were three late deaths (one sudden, one stroke and one trauma). Eight of the 17 survivors (47%) are asymptomatic. According to the MRC/ATS grading system, the dyspnoea score was 2.06+/-0.97 preoperatively and 1.06+/-1.14 postoperatively (p=0.007). At follow-up, the FEV(1) was 76.1+/-20.1% and the VC was 78.4+/-17.3% (p>0.1). Two patients had chronic pain. Conclusion: Plication of the diaphragm is a safe and efficient procedure. Most patients experienced significant clinical improvement with enhancement of the FEV(1) and VC. Chronic surgical pain still remains a potential problem with the classical approach

Latent space transformers for generalizing deep networks

Sharing information between deep networks is not a simple task nowadays. In a traditional approach, researchers change and train layers at the end of a pretrained deep network while the other layers remain the same to adapt it to their purposes or develop a new deep network. In this paper, we propose a novel concept for interoperability in deep networks. Generalizing such networks’ usability will facilitate the creation of new hybrid models promoting innovation and disruptive use cases for deep networks in the fifth generation of wireless communications (5G) networks and increasing the accessibility, usability, and affordability for these products. The main idea is to use standard latent space transformation to share information between such networks. First, each deep network should be split into two parts by creators. After that, they should provide access to standard latent space. As each deep network should do that, we suggest the standard for the procedure. By adding the latent space, we can combine two deep networks using the latent transformer block, the only block that needs to train while connecting different pretrained deep networks. The results from the combination create a new network with a unique ability. This paper contributes to a concept related to the generalization of deep networks using latent transformers, optimizing the utilization of the edge and cloud in 5G telecommunication, controlling load balancing, saving bandwidth, and decreasing the latency caused by cumbersome computations. We provide a review of the current standardization associated with deep networks and Artificial Intelligence in general. Lastly, we present some use cases in 5G supporting the proposed concept.info:eu-repo/semantics/acceptedVersio
