Performance analysis of the VBLAST algorithm for MIMO-OFDMA systems on spatial correlated channels

This paper investigates the performance of Vertical Bell Laboratories Layered Space Time (V-BLAST) architecture for multi input multi output orthogonal frequency division multiple access (MIMO-OFDMA) system. VBLAST is a successive cancellation method applied to the receiver to obtain the highest SNR. Performance of MIMO systems in realistic radio environments greatly depends on the spatial correlation due to the presence of scatterers in the multipath propagation environments. The number of users using in the system are also analyzed. It is assumed that all antennas have same radiation pattern and the spatial correlation is independent on the position of an antenna in the array. Our results are simulated on Monte Carlo and One Ring channel model for 2×2 MIMO OFDMA system. From the results, we can see that VBLAST-ZF show the best SER performance in one ring channel model with long term evolution (LTE) standard.
Sismicidad y sismotectónica para el sector norte del ámbito del Sistema de Fallas de Algeciras, Cordillera Oriental, Colombia

Al Sistema de Fallas de Algeciras (SFA), se le han asignado cuatro sismos históricos desde finales del siglo XVIII, que en términos de magnitud recalculada desde análisis macrosísmicos tuvieron una magnitud M&gt;6.5. Uno de estos, el del 9 de febrero de 1967, fue registrado instrumentalmente con Mw 7.2. En este trabajo se realizó un estudio del sector norte de este sistema de fallas entre los 3° y 4°N. Entre el 31 de octubre de 2016 y el 18 de julio de 2018, se presentaron cuatro sismos con Mw&gt;4.8, que la Red Sismológica Nacional de Colombia (RSNC) localizó en el municipio de Colombia, departamento del Huila, asignándolos a fallas del SFA. Luego, en diciembre 24 de 2019, se presentó un sismo con Mw 6.0, que se asignó a la Falla Algeciras perteneciente al SFA en el departamento del Meta. En esta investigación se encontró que los sismos de la región de Colombia se produjeron en las fallas Altamira y Nazareth, las cuales son fallas inversas en un contexto tectono - estratigráfico diferente al SFA. El SFA al norte de los 3°N define en esta región el piedemonte llanero. Para las fallas Altamira y Nazareth, los mecanismos focales indicaron fallas inversas, mientras que en la región de Mesetas estos mecanismos obedecieron a fallas transcurrentes concordantes con el SFA. Dada la alta generación de sismos con Mw&gt;5.0 en estas fallas en un lapso inferior a 10 años, se establece que su potencial sismogénico contribuye de manera importante a la amenaza sísmica del centro y el suroccidente de Colombia, sin embargo, en este trabajo se encontró además que la denominada Falla Algeciras, principal componente del SFA por la literatura, está segmentada y no es continua, por lo que se debe revaluar su potencial sismogénico.
Green night

Taking its name from the European Green Deal, GREEN NIGHT stands on the main pillars and policy areas of the strategy with a general outlook on how science can support the aims and targets set out for Europe?s near future. The current global climate emergency urges an immediate and large-scale response from the countries. For the first time, climate change and environmental issues are seen to have migrated to the center of global policymaking. 

As a result, GREEN NIGHT highlights the importance of raising awareness of the general public, especially young people, on the necessity of the green transformation for the future of our planet. GREEN NIGHT acknowledges that it is essential to protect and restore natural ecosystems for sustainability. Doing so, GREEN NIGHT will focus on main action areas of energy, food, waste, and transportation, and demonstrate the leading role that sciences have in how to achieve this transformation. 

GREEN NIGHT project brings together four of the ten higher education institutions in Izmir, Turkey as well as the provincial directorate of national education. The consortium represents the scientific research ecosystem and educational management in ?zmir. The HEIs cooperate in local, national and international research projects, joint social responsibility campaign and activities all of which create strong institutional linkages between HEI partners. IZMEM, being the highest local public body responsible for the coordination of educational activities in preprimary, primary and secondary level in ?zmir, brings the public educational expertise into the project.

The night activities will be carried out in four campuses around the city, each with its general theme selected from the main topics. Scientists and researchers from a wide range of disciplines will be able to create workshops, seminars, demonstrations, hands-on experiments, games, competitions, shows, or simulations.
Effect of background plasma on electromagnetic properties of coaxial gyrotron cavity

We analyze the effect of the background plasma on the electromagnetic properties of coaxial resonators with a smooth and a corrugated inner conductors used in high-power gyrotrons. It is shown that the plasma produces different effects on the modes with different signs of the azimuthal index, leading to a decrease or an increase in the resonance frequencies. A modification of the distributions of electromagnetic fields and the electromagnetic energy density by the background plasma occurs in such a way that Ohmic losses decrease both on the inner and on the outer conductors. In the case of a smooth inner conductor, this is due to a decrease in the field strengths on the surface of the conductors. If the inner conductor is corrugated, the background plasma leads to an increase in the field strengths on its surface. Nevertheless, the relative Ohmic loss power decreases due to an increase in the energy density in the resonator (which is also caused by the background plasma). Calculations were mainly performed for a coaxial resonator of a gyrotron operating on the TE34.19 mode (Karlsruhe, Germany).
Reclosable food carton for preventing entry of insects

The food carton prevents access to the contents, especially by insects. The carton has a closing tab (21) or rip-strip (37) with scores (23,24) in the front and in the rear face, respectively. The front and rear score marks are laterally transposed but cross over at one or more points. The resulting tear- open panel has a finger tab (28) which is depressed to create finger tip access to the closure tab and rip strip.
Fatigue Analysis of Column-Brace Connection in a Semi-submersible Wind Turbine

The importance of offshore renewable energy from wind is expected to increase in the future. Most offshore wind turbines are currently installed in shallow water up to 50 meter water depth on bottom mounted substructures. To harvest more wind energy at deeper waters, offshore floating support structures are needed. Semi-submersible floating wind turbine is one of the proposed floating concepts. Under simultaneous wind and wave loads, fatigue might be an important design consideration. Study of fatigue for such structures is thought to contribute to a better understanding of offshore wind turbines. A local part of a semi-submersible wind turbine was studied. The column-brace connection, or joint, connected a wind turbine tower to a triangular semi-submersible floater. Design, stress concentration factors and fatigue damage of the part were the main topics. To calculate stress concentration factors and fatigue damage, dynamic response analyses and finite element modelling were performed. Only the fatigue limit state was considered. Three different column-brace connection designs were analysed. For the initial design, the stress concentration factors generally were way too large - especially for out-of-plane action. For the third design a horizontal bulkhead at the brace centreline was added. This modification decreased the stress concentrations by a maximum of over 90% for out-of-plane action. The modification was only carried out for brace 1. A long-term fatigue approximation with distribution of mean wind speed in the northern North Sea was considered, while the expected significant wave height and spectral peak period for a given mean wind speed were used, to reduce the simulation effort. The critical fatigue damage was observed for brace 2, with a life time of less than a year. For brace 1 the lowest life time was several hundred years, meaning a conservative design. By reducing and optimizing the brace thickness, one could reduce such conservatism. The critical hot-spot-stresses were found at the crown toe and heel for both brace 1 and brace 2. All fatigue calculations included a design fatigue factor of 3. The modification of brace 1 with horizontal bulkheads as additional stiffening reduced the stress concentrations significantly, and increased the fatigue life considerably. Brace 2 still needs to be modified to decrease the stress concentrations, and thus increase the fatigue life.
Process Capability Studies in Heat Treatment

Process capability, which is an important concept within statistical process control (SPC), describes the ability of a process i.e. a thermal process to produce components within the tolerance limits.
The purpose of this study was to identify possible methods for how to perform process capability study and temperature uniformity survey. In this essay the capability of the case hardening at continuous furnaces have been studied, considering a number of quality parameters. The outcome form these parameters described how well the process could produce components within the tolerances. The parameters of interest were case depth, core hardness, surface hardness, and surface carbon content. Practical work was done at Volvo Construction Equipment (VCE), Eskilstuna and Getrag All Wheel Drive AB, Koping. The parameters were measured from dummy test specimens in Getrag All Wheel Drive AB, and were analyzed by statistical software Minitab version 16.
 
Temperature uniformity surveys (TUSs) were studied for both companies according to standard AMS 2750 D. However, it was not written in it how to make analysis of temperature data. In TUSs, a datapaq with ten thermocouples where used during production from which the temperature could be logged at different positions of the stacking trays and over the entire cross-section of the furnaces. The furnace temperature was within the specified tolerances; however, the significant differences within each track from each of the furnaces were recorded. One of the furnaces was constructed with two parallel tracks while the other was constructed with three parallel tracks. It’s related with the ratio of production capacity for the actual furnace, it will also give information of how the degree of production capacity is influenced by temperature uniformity.
The author recommends that both companies perform the same test next year. It is also recommended that further research should be carried out by the methodology that was utilized in this essay.
Taxonomy for Rich-User-Interface Components: Towards a Systematic Development of RIAs

The development of Rich Internet Applications (RIAs) is based on the selection, assembly, and tailoring of Rich-User-Interface (RUI) components. While the user interface design is usually guided by principles, guidelines, and heuristics, there are not mechanisms for systematically selecting RUI components. Moreover, there is a lack of homogeneous classification criteria that hinders the selection of components and increases the relevance of experience designing web applications. To ease the search and the choosing of components by web-developers, this paper presents a taxonomy for classifying RUI components. The development of such a taxonomy has been based on both the study of relevant resources from the UI domain and the opinions of experts.
Feature-Gating in superior colliculus

Imagine a huge elephant rushing towards you; your first instinct is – run! This innate escape response is triggered by visual cues, here, a fast expanding object, and crucially depends on the extraction of few relevant features. The processing of visual information starts in the retina where more than 40 types of retinal ganglion cells extract salient features from the visual scene. Information about these features is sent to downstream brain areas. A central node where retinal signals are integrated is the superior colliculus. This evolutionary-conserved brain area controls innate behaviors, directly linking the outputs of the retina with the activation of motor outputs and behavior. In mice, escape behaviors can be initiated upon activation of a single cell type of superior colliculus, wide-field neurons. They receive inputs from a subset of retinal ganglion cell types and respond preferentially to two distinct visual stimuli, slow moving dots and quickly expanding disks, each known to trigger defensive behaviors. However, the computational strategy used by collicular neurons to process feature-selective retinal inputs remains unknown. 
In the proposed project, I will identify the mechanisms by which retinal features are integrated in collicular wide-field neurons. I will combine transsynaptic viral circuit tracing with two-photon calcium imaging to identify and characterize the feature-selective inputs from retinal ganglion cells (in-vitro) and functional outputs of wide-field neurons (in-vivo). The results of these experiments will allow me to deduce how the output features of wide-field neurons arise from the retinal inputs using computational modeling and neural decoding techniques. This will reveal the circuit and computational principles by which retinal feature-selectivity drives complex circuit function in central brain regions.
Visual health assessments for palms

Abstract Palms (family Arecaceae) can make up a significant portion of the urban forest in the climates where they are viable. Despite this, they are rarely included in the urban forest growth and longevity literature. One difficulty associated with including palms in research is an absence of a standard means for characterizing tree health or condition. Whether used as a measured response of its own or incorporated as a predictor of future mortality, standardized and meaningful health ratings are needed to advance the care and management of palms in urban areas. In this short communication, we investigate some of the rating systems used in past palm research. We then propose an adaptation of existing tree health rating processes based on insights from these past attempts and our own experience in qualifying palm health.
Open-Air laboratories for nature based solutions to manage environmental risks

Severe hydro-meteorological phenomena are having a high impact in European territories and are of global concern. The science behind these phenomena is complex and advancement in knowledge proceeds with progress in data acquisition and forecasting useful for real-scenario interventions. The employment of nature-based solutions (NBS) to mitigate the impact of hydro-meteorological phenomena is not adequately demonstrated, still uncoordinated at the European level, therefore not reaching full potential. Actions to achieve highest NBS impact requires strategies to enhance societal acceptance, policy strengthening while demonstrating advantages for market development. 
The objective of OPERANDUM is to reduce hydro-meteorological risks in European territories through co-designed, co-developed, deployed, tested and demonstrated innovative green and blue/grey/hybrid NBS, and push business exploitation. It aims provision of science-evidence for the usability of NBS, best practices for their design based on participatory processes. It foresees a multiple level of stakeholders engagement from the local community up to the international level to leverage widest possible NBS acceptance to promote its diffusion as a good practice.   It establishes the framework for the strengthening of NBS-based policies according to local legislation and promotes technology and innovation in NBS to create a European leadership. 
OPERANDUM is based on open-air laboratories (OALs), a fairly new concept that expands the Living Labs to a wider vision for natural and rural areas. In OALs novel NBS in seven European countries and three in China and Australia are implemented to address specific risks and their effectiveness, assessed through innovative monitoring systems and cutting-edge numerical modelling approaches. OPERANDUM realizes a multi-dimensional open and flexible platform enabling stakeholders and end users to improve knowledge in NBS to mitigate climate change as well as ways to promote and exploit the improved/preserved environment while increasing business opportunities.

L-leucine improves the anemia and developmental defects associated with Diamond-Blackfan anemia and del(5q) MDS by activating the mTOR pathway

Haploinsufficiency of ribosomal proteins (RPs) has been proposed to be the common basis for the anemia observed in Diamond-Blackfan anemia (DBA) and myelodysplastic syndrome with loss of chromosome 5q [del(5q) MDS]. We have modeled DBA and del(5q) MDS in zebrafish using antisense morpholinos to rps19 and rps14, respectively, and have demonstrated that, as in humans, haploinsufficient levels of these proteins lead to a profound anemia. To address the hypothesis that RP loss results in impaired mRNA translation, we treated Rps19 and Rps14-deficient embryos with the amino acid L-leucine, a known activator of mRNA translation. This resulted in a striking improvement of the anemia associated with RP loss. We confirmed our findings in primary human CD34⁺ cells, after shRNA knockdown of RPS19 and RPS14. Furthermore, we showed that loss of Rps19 or Rps14 activates the mTOR pathway, and this is accentuated by L-leucine in both Rps19 and Rps14 morphants. This effect could be abrogated by rapamycin suggesting that mTOR signaling may be responsible for the improvement in anemia associated with L-leucine. Our studies support the rationale for ongoing clinical trials of L-leucine as a therapeutic agent for DBA, and potentially for patients with del(5q) MDS.

Practice Positioning of Wealth Evolution Phases

Some scholars sum up the development of the concept of wealth from the angle of economic meaning in four phases currently. But there is a lack of an analysis based on practical thinking, so the explanation of evolution process of the concept of wealth and the essence of each phase is not perfect and lacks the foundation of philosophical theories. The positioning of the essence of wealth differs due to people’s engagement in dissimilar fulfillment form in the different periods. Even if from the angle of economic meaning, it varies because of the different evolution of each industrial form. The paper applies the production practice to explain the transmission of the positioning of the essence of wealth, and suggests that people must form a dialectical idea of the wealth and eradicate metaphysics.
Biomarker enterprise to attack dkd - sofia ref.: 115974

Diabetic kidney disease (DKD) is the leading cause of end stage renal disease (ESRD), and its global incidence and prevalence have reached epidemic dimensions in recent years. Unfortunately, there are no effective means to prevent or cure DKD, the few existing treatments have limited effect and very few alternative therapies have emerged in the past years. Lack of new predictive and prognostic biomarkers for a more accurate patient stratification, limited access to kidney tissue from patients at various stages of DKD as well as novel model systems to better understand the pathogenesis of the disease, are likely reasons for the stagnating development of new treatments.

The BEAt-DKD consortium combines outstanding basic and translational researchers in nephropathy, diabetes, kidney model systems, imaging techniques and systems biology, and includes leaders of diabetes and kidney disease-relevant
IMI1, FP7 and US consortia, like SUMMIT, KIDNEYCONNECT, Syskid, CPROBE and C-Path, in an unprecedented search for new and better biomarkers for DKD, through a better understanding of the disease.

Jointly, the partners have access to vast and very relevant clinical cohorts and trials, state-of-the-art analysis and imaging techniques, novel model systems and the long-standing experience and networks to make this collaboration a success. By involving regulatory agencies throughout the project, BEAt-DKD aims at making the introduction and acceptance of new tools as efficient as possible.

The overall goals of BEAt-DKD are (1) to provide a holistic systems medicine view of the pathogenesis of DKD with the aim to identify targetable mechanisms and pathways underlying initiation and progression of DKD, applying a novel sub-classification of diabetes, and (2) to identify and validate biomarkers of disease progression and treatment responses representing first steps towards precision medicine in the management of DKD.
Optimized operation and maintenance costs to improve system reliability by decreasing the failure rate of distribution lines

Improving distribution system reliability has received a great deal of attention in recent years. Because of the limitation in expected budgets, it is desirable to determine the most efficient strategy to improve system reliability. This paper proposes a novel method to determine the optimized operation and maintenance costs in order to decrease the failure of system components. The proposed objective function includes the average system frequency interruption index (ASIFI) value. To achieve the best strategy to decrease failures of system components, it is necessary to find the minimum value of the objective function, considering the constraints of operation and maintenance costs. A genetic algorithm is used to solve the optimization problem. Moreover, a new mathematical model to calculate system reliability indices, including the ASIFI, is introduced. The proposed method is applied to a realistic distribution system. The results illustrate the effectiveness of the proposed method in order to increase the system reliability in an optimal manner.
