Integrated Algorithm for Selecting the Location and Control of Energy Storage Units to Improve the Voltage Level in Distribution Grids

This paper refers to the issue that mainly appears in distribution grids, where renewable energy sources (RES) are widely installed. In such grids, one of the main problems is the coordination of energy production time with demand time, especially if photovoltaic energy sources are present. To face this problem, battery energy storage units (ESU) can be installed. In recent years, more and more attention has been paid to optimizing the use of ESU. This paper contains a simple description of available solutions for the application of ESU as well as an original proposal for selecting the optimal location and control of ESU. The ESU selection method is based on the use of a genetic algorithm and the ESU control method utilizes the fuzzy logic. The combination of the aforementioned methods/algorithms of ESU application is named an integrated algorithm. The performance of the proposed algorithm was validated by multivariate computer simulations with the use of the real low-voltage grid model. The DIgSILENT PowerFactory environment was employed to develop the simulation model of the integrated algorithm. The proposal was utilized to improve the voltage level in the distribution grid and to install the optimal number of ESU. Based on daily load variations for selected load profiles, it was shown that after the ESU application the voltage deviations in the analyzed network were significantly limited. Moreover, the analysis proves that both the location of ESU in the grid and the control of their active and reactive power are important from the point of view of reducing overall costs.
Utilidad de la espirometría en los pacientes hospitalizados por la enfermedad pulmonar obstructiva crónica (EPOC) exacerbada

La espirometría es la prueba estándar para confirmar el diagnóstico de la enfermedad pulmonar obstructiva crónica (EPOC). En los servicios de hospitalización es frecuente encontrar pacientes que ingresan con sospecha de esta condición durante una exacerbación. Con base en las guías actuales, existe controversia sobre si se puede o no realizar la espirometría en este escenario. Objetivo: revisar la utilidad diagnóstica de la espirometría en pacientes hospitalizados con sospecha de EPOC exacerbada. Metodología: se realizó una revisión no sistemática hasta noviembre del 2019. Las bases de datos consultadas fueron PubMed, Cochrane, EMBASE, LILACS, Google Scholar. Se incluyeron estudios prospectivos en pacientes mayores de 18 años, en idioma inglés y español. Se encontraron 573 artículos y se seleccionaron 20 artículos de relevancia para la discusión. Conclusiones: en los pacientes hospitalizados por sospecha de EPOC exacerbada, la espirometría es una herramienta útil para confirmar el diagnóstico. El momento para realizarla es previo al egreso, una vez el paciente está estable. Anotamos que el VEF1 no sería útil para establecer la gravedad.
Weak Decay of Tellurium and Barium Isotopes in Geological Samples: Current Status

The accurate experimental determination of half-lives for 2-decay could be used to adjust parameters of the QRPA model, the strength of the particle-particle interaction gpp and to improve the calculation of Nuclear Matrix Element for 0 (neutrinoless) decay and neutrino mass m estimations. Presently high precision direct counting experiments are difficult due to low decay rates of tellurium and barium isotopes, but their daughter nuclei accumulating in geological samples for millions of years, are clearly observable in xenon isotopes, which have extremely low background in terrestrial rocks. This work reviews current status of the previously determined half-lives of 130 Te and 128 Te and presents new estimates of half-life of 130 Ba weak decay. Our new estimates take into account the spallogenic production of 130 Xe, significantly reducing the disagreement between the only two published values of 130 Ba half-lives. Based on this result and on our early experiments we propose a new class of geological samples, which can provide an even more accurate determination of the 130 Ba half-life.
Peer-to-peer electricity transaction decision of user-side smart energy system based on SARSA reinforcement learning method

With the deep integration of advanced information technologies such as artificial intelligence and traditional energy technologies, smart energy systems have been proposed as a method to provide the best solution for the coordination, balance, and control of the entire energy system. As a new way of energy balance and interaction in the user side energy market, peer-to-peer (P2P) electricity transaction can effectively promote energy sharing within the user group and improve the economic benefits of users participating in the energy market. Reinforcement learning (RL) is an artificial intelligence method in which agents continuously acquire relevant experience and knowledge during the interaction with the environment, automatically update their decision-making behavior, and achieve maximum return. It is suitable for P2P transaction decision analysis of small-scale users in the context of smart energy. Firstly, this paper establishes a P2P transaction model that includes a participant model, equipment model and price model. Secondly, the transaction problem is equivalent to a Markov decision process (MDP) and each learning element model is established. Then, the MDP problem is solved and analyzed using SARSA RL algorithm with average discrete processing. Finally, a case study of a community with multiple users is conducted to verify the effectiveness, economy, and security of RL method in solving energy storage action selection and transaction decision problems of energy storage users.

Standing out while fitting in: Examining linguistic choices by boundary spanners

ABSTRACT Boundary spanners live a precarious social life. They need to stand out to receive ideas from different groups and fit into some groups enough to influence their peers. We investigated how boundary spanners make linguistic choices to manage the tension of distinctiveness and belonging. We identified boundary spanners based on their betweenness centrality in a large review network (23,851 users and 118,545 reviews). We found that, compared to non-boundary spanners, boundary spanners used less bonding language to set themselves apart, but used more utility language to enhance social value. Boundary spanners’ use of bonding language varied with their popularity in social networks. More (vs. less) popular boundary spanners showed a stronger tendency to avoid we-words but not positive emotional words.

QUALITY INDICATORS FOR MODIFIED ATMOSPHERE PACKAGING (MAP) STORAGE OF HIGH-QUALITY EUROPEAN PLUM (PRUNUS DOMESTICA L.) CULTIVARS

The use of quality indicators is crucial in selling plums in more distant markets and the evaluation of freshness through multiple index is fundamental to evaluate the goodness of the storage technique. In this study we evaluated the quality of two european plums cultivars ('Ramasin' and 'Ariddo di Core' with purple and yellow flesh colour respectively) after modified atmosphere packaging (MAP) storage, through the selection of the most appropriate indicators. The headspace gas composition, the flesh fruit firmness (FFF), the soluble solid content (SSC), the titratable acidity (TA), the colour and the chlorophyll content of plums wrapped with 5 different films (F1, F2, F3, F4 and F5) were evaluated for up 21 days of storage (at 1±1°C and 90-95% relative humidity). For both cultivars, the multilayered films (F1 and F2, 90 and 65 µm respectively) offered better effectiveness over other films. The total chlorophyll concentration, showing a good correlation with the colorimetric parameters of luminance (L*) and chroma (respectively R 2 =0.92 and R 2 = 0.96) confirmed, in the case of the Ariddo di Core cultivar, the results obtained by monitoring other parameters thus highlighting the usefulness of integrating multiple indexes in evaluating the performance of the storage methods used.
Evaluation of growth traits in three strains of broiler chicken

This study was carried out to evaluate the growth performance of Marshall, Cobb and Arbor acre strains of broiler chicken. A total number of three hundred (300) day-old broiler chicks of Arbor acre, Cobb and Marshall strains were raised under the same management condition. Data was obtained on the growth performance and analyzed. Cobb strain had the highest weight of 175.78 ± 2.51g at 2 weeks of age while Arbor acre and Marshall strain had similar (p>0.05) body weight at that age. Marshall had the highest body weight of 1804.37± 50.47g followed by Cobb with a weight of 1760.16 ±15.38g) while Arbor acre had the least body weight of 1683.43 ± 25.06g at 8weeks. Cobb strain had the highest body length (32.33 ± 0.10cm) at 8 weeks. All the strain studied had similar breast girth at 4 weeks. However, Marshall strain had the highest breast girth followed by Arbor acre while Cobb strain had the least breast girth at maturity. Marshall strain and Arbor acre had similar thigh lengths while the least thigh length was recorded for the Cobb strain. The effect of sex was significant (p<0.05) on all the growth parameters at 8weeks as male broilers had higher body measurements than their female counterparts. In conclusion, Marshall strain had better growth performance than Arbor acre and Cobb strain of broiler chicken.
DEVIATIONS FROM THE EMPIRICAL SODIUM ADSORPTION RATIO (SAR) AND EXCHANGEABLE SODIUM PERCENTAGE (ESP) RELATIONSHIP

Accurate information on exchangeable sodium percentage (ESP) is important in reclamation of sodium (Na)-affected soils. Representative soil samples were collected at six depths (0-5, 5-15, 15-30, 30-60, 60-90, and 90-120 cm) from five sites in the Powder River Basin (PRB), Wyoming, that have been irrigated with saline-sodic water [electrical conductivity of irrigation water (ECiw) >2 dS m−1 and sodium adsorption ratio of irrigation water (SARiw) >20 mmol1/2 L−1/2] for up to 3 years. Soil ESPs were determined using NH4OAc (ESPm) and the ESP-SAR empirical relationship (ESPe) recommended by U.S. Soil Salinity Laboratory Staff. Measured ESPm values were significantly lower (P < 0.05) than ESPe determined by the empirical relationship in the upper 30 cm; except for site 2, all remaining profiles had no statistically significant relationships for 30- to 120-cm depth samples. Significantly lower ESPm in these soils could be due to a combination of overcorrection for soluble Na because of salinity and underestimation of exchangeable Na due to fixation of the NH4+ index ion by smectitic clay minerals present in the PRB soils. Thus, using an appropriate extractant to determine the exchangeable Na and using a correction factor for accurate evaluation of soluble Na concentrations are important for developing suitable amendment plans for correcting sodicity hazard in saline-sodic waters used to irrigate soils of the PRB region.

Tie-Dye! An Engaging Activity To Introduce Polymers and Polymerization to Beginning Chemistry Students

A stand-alone polymer unit, centered on a tie-dye activity, was used to introduce the concept of polymers and the process of polymerization to three different groups of beginning-level chemistry students. This polymer unit consists of three parts. First, each student used a molecular model kit to construct the monomer units, β-d-glucose. Students combined these monomer units to learn the polymerization process and visualize the formation of the cellulose polymer in conjunction with writing the balanced equation for the polymerization reaction. Second, students tie-dyed cotton t-shirts made of cellulose fibers using dyes purchased from local craft stores. Finally, a primary literature exercise engaged students in understanding the chemical reactions that bind the cellulose fibers to the dye molecules permanently, producing a colorfast tie-dyed t-shirt. This stand-alone polymer unit can be used in any beginning college or high school chemistry course to introduce students to polymer chemistry and the proces.
A High-Performance Core Micro-Architecture Based on RISC-V ISA for Low Power Applications

Design of high-performance processors with very low power requirement is the primary goal of many contemporary and futuristic applications. This brief presents a novel processor micro-architecture which is capable of achieving these requirements. The micro-architecture is based on RISC-V Instruction Set Architecture (ISA). The core is implemented and verified on Xilinx Virtex-7 FPGA board with a resource requirement of 7617 LUTs and 2319 FFs. This core could achieve a Dhrystone benchmark score of 1.71 DMIPS per MHz which is higher than ARM Cortex-M3 (1.50 DMIPS per MHz) and ARM Cortex-M4 (1.52 DMIPS per MHz). The Coremark benchmark is also tested on this core and it gives 4.13 Coremark per MHz. The physical design result of the core using commercial tools shows that it can achieve a maximum frequency of 198.02 MHz with 0.036 mm<sup>2</sup> area and <inline-formula> <tex-math notation="LaTeX">$17.36~\mu \text{W}$ </tex-math></inline-formula>/MHz power requirement at UMC 40 nm technology node. The core consumes a dynamic power of <inline-formula> <tex-math notation="LaTeX">$19.75~\mu \text{W}$ </tex-math></inline-formula>/MHz at UMC 90nm which is 36% and 40% better than ARM Cortex-M3 and Cortex-M4 respectively and also lower than many others cores. The results show that this core can outperform many existing commercial and open-source cores.
Contrasting Altitude and Long-term Geographical Isolation Shaped Phylogeography of Himalrandia  lichiangensis, an Endemic Species from the Dry Hot Valley of Southwest China

Background: The eastern Sino-Himalayan region of southwest China, as one of the world’s biodiversity hotspots, has undergone dramatic geomorphological and climatic changes during the Late Tertiary/Quaternary. The dry-hot valleys in southwest China is overlapping with the Hengduan Mountains. However, when this endemism was assembled in dry-hot valleys and how the climatic oscillations and/or tectonic movements influence their phylogeographical patterns remained largely unknown. Himalrandia lichiangensis is a shrub of Rubiaceae, endemically distributes in dry-hot valleys of southwest China. By integrating evidences from phylogeography, population dynamic and ecological niche modelling, we are aiming to trace the evolutionary history and explain the origin of biodiversity and endemism in the dry-hot valleys of southwest China. Results: Based on sequencing four chloroplastic non-coding regions (psbM-trnD, trnD-trnT, atpB-rbcL and accD-psaI) and two single-low copy nuclear genes CAMX (Calmodulin) and ITS of 423 individuals from 23 populations, we found high genetic variation mainly existed between the populations (cpDNA: 89.80％, ITS: 84.55％, CAMX: 95.68％). Haplotypes in different river basins showed significant phylogeographical structure. The geographical distribution of haplotypes indicated that there is a high degree of genetic differentiation and this differentiation is associated with altitude discrepancy. BARRIER analysis detects a strong geographic barrier between the Nanpan River and Jinsha River. The MaxEnt result shows that the suitable distribution area was the largest in the LGM. The future climate warming will lead to the niche expansion for H. lichiangensis but will also cause fragmented distribution.Conclusions: Our study highlighted the importance of altitude in explaining the genetic differentiation. The current phylogeographical pattern of H. lichiangensis may be shaped by long-term geographical isolation resulted from the uplifting of Himalaya, which gives rise to the barriers from the Hengduan Mountain or multiple river systems, and the vertical altitude discrepancies that both limited gene flow among regions. The Middle Jinsha River valley is most likely to be a main refuge for H. lichiangensis till now, and the glaciation retreat may account for the high endemism of plants in the dry-hot valleys of southwest China.
Effect of Antenatal Exercises on Second Stage of Labor Outcomes in Nulliparous Women

ABSTRACT The second stage of labor (SSL) has often been neglected, leading to birthing complications, perinatal morbidities, and higher rates of cesarean section (CS) in nulliparous women. In this paper, it was aimed to determine the effect of antenatal exercises on labor outcomes in nulliparous women. Two-group posttest-only randomized study. Overall, 60 nulliparous women at their 30th to 32nd weeks of gestation were allocated into two groups randomly. Group (A) received only routine antenatal care and educational instructions till the time of delivery (n=30), while group (B) received the same routine antenatal care and educational instructions in addition to antenatal exercises till the time of delivery (n=30). Comparing both groups revealed that group (B) had a significant increase in the number of spontaneous vaginal deliveries (p<0.05) and a significant decrease in duration of SSL (p<0.05), without any need to admit their neonates to the neonatal intensive care unit (NICU).
Machine Learning-Based Individual Identification of Laboratory Mice

Background and Objective: Individual identification of laboratory animals is essential in behavioral science. Conventional methods often involve invasive marking of the animalsʼ bodies and may cause infectious diseases. The purpose of this study was to establish an accurate and non-invasive method for the individual identification of native laboratory mice. Materials and Methods: A total of 706 photographs of four mice were taken. Using the photographs, an open-source computing algorithm method was adopted to create a model that identified individual mice. Results: Using the high-resolution photographs and the open-source computing algorithm with deep learning, an accurate algorithm for individual identification of mice, which outperformed classical identification algorithms, was established. Conclusion: Compared with the other conventional methods, this model exhibited higher performance in individual identification of mice. It will provide a platform to automatically label individual mice for social behavioral experiments
Effects of sludge settling characteristics in the BNR system

Although the BNR system design assumes no sludge settling problems in the final settling tank, the fluctuation of daily loading and up to 40% of anaerobiosis in the BNR system would be considerable factors in determining the sludge settleability. The sludge volume index (SVI) is a classical parameter to examine the sludge settleability but it has a limited value to evaluate the overall settling characteristics. The extracellular polymer (ECP) content in sludge has long been considered as an indicator of biological flocculation in activated sludge process, but the skepticism on analytical accuracy limits the usage in settling study. This study focused on evaluating the BNR system performance related to the sludge settling characteristics under the controlled laboratory environment. A 5-stage BNR system (anaerobic-anoxic-3 stage oxic) was operated with the HRTs from 3.9 to 7.6 hours. In order to determine the sludge settling properties, both SVI and ECP content were monitored. The ECP contents in the sludge sample were measured by the slime-washing step followed by high-G centrifugation and sonication. The gel-electrophoresis was used to detect the DNA in the sonicated samples to determine the intracellular polymer contamination. It has been found that the anaerobiosis in the anaerobic and anoxic zone that consisted of 37% of reactor volume could not deteriorate the sludge settling properties even at the HRT of 3.9 hours. The SVI values of sludge taken from the reactor with the HRT of 7.2 hours averaged to less than 50 mL/gr. It was postulated that a fast settling sludge in the BNR system could not always ensure production of clear effluent. The sludge with very low SVI might not achieve a complete biological flocculation potential. In addition, the degree of denitrification in the BNR system could be related to the sludge settleability.
