Authors: Kurc-Lisiecka Agnieszka , Lisiecki Aleksander 
Published: July 2019

Abstract
The results of investigations on hybrid laser + gas metal arc (GMA) welding of butt joints of different fine-grained and thermomechanically rolled steel plates 5.0 mm thick are presented in the article. The hybrid welding tests were carried out on steel grade Domex 700MC, Domex 960, and Domex 1100. The experimental stand for hybrid welding consisted of the laser welding head and also the arc GMA torch. Butt joints of Domex 700MC plates were hybrid welded applying a metal cored wire Stein Megafil 742B (Charpy V: 80 J at −20°C). In turn, the butt joints of Domex 960, and Domex 1100 steel plates were hybrid welded applying a metal cored wire Stein Megafil 1100M (Charpy V: 55 J at −20°C). The quality of the test joints was analyzed by means of visual inspection and cross-section observation. In turn, the mechanical properties were evaluated by means of a static tensile test of the welded joints and also impact toughness of the weld metal. The results showed that the hybrid welding can provide a proper shape of weld even at altering gap between the butt surfaces of the groove and also at distinct shift of the electric arc to the laser beam spot. Results of tensile tests showed that the hybrid welded joints of Domex 960 and 1100 have the strength at similar levels of approximately 1,140 MPa, which is significantly higher compared to the joints of Domex 700MC at approximately 820 MPa. In turn, the weld metal of the Domex 700MC steel exhibited the highest impact toughness at a mean value of 139 J/cm2, whereas the test joints of Domex 960 showed lower impact toughness at approximately 122 J/cm2. Surprisingly, the lowest impact toughness was determined for the joints of Domex 1100, despite the same wire being applied for the Domex 960.

Published: July 2019

AbstractOne way that drugs of abuse perturb the dopamine system is by triggering large amounts of extracellular dopamine to efflux into limbic regions. The basolateral (BLA) and central (CeA) nuclei of the amygdala have been shown to play distinct roles in value representation of primary and conditioned reward. However, the precise role of dopaminergic receptors in the BLA and the CeA during reward-related behaviors remains to be determined. Here we investigate the effects of dopamine D1 receptor blockade in the BLA and the CeA during asymptotic performance of cocaine self-administration and in a novel application of contextual renewal under continued access conditions. After more than three weeks of chained seek-take self-administration of cocaine, male Long Evans rats were given a bilateral intra-BLA or intra-CeA infusion of the D1 antagonist SCH-23390 (2 µg/0.3 µl) for multiple days. Intra-BLA D1 receptor blockade before, but not after the self-administration session, gradually suppressed drug seeking and taking responses and persisted with a change in context with continued D1 blockade. In contrast, intra-CeA D1 receptor blockade caused a rapid reduction in self-administration that showed renewal with a change in context with continued D1 blockade. Further, conditioned place aversion developed with intra-BLA but not intra-CeA infusions. Collectively, these results demonstrate that dopamine D1 receptors in the BLA and CeA both contribute to drug seeking and taking, but may do so through distinct mechanisms.
Unraveling Synaptic GCaMP Signals: Differential Excitability and Clearance Mechanisms Underlying Distinct Ca2+Dynamics in Tonic and Phasic Excitatory, and Aminergic Modulatory Motor Terminals inDrosophila
Authors: Xing Xiaomin , Wu Chun-Fang 
Published: July 2019

AbstractGCaMP is an optogenetic Ca2+sensor widely used for monitoring neuronal activities but the precise physiological implications of GCaMP signals remain to be further delineated among functionally distinct synapses. TheDrosophilaneuromuscular junction (NMJ), a powerful genetic system for studying synaptic function and plasticity, consists of tonic and phasic glutamatergic and modulatory aminergic motor terminals of distinct properties. We report a first simultaneous imaging and electric recording study to directly contrast the frequency characteristics of GCaMP signals of the three synapses for physiological implications. Different GCaMP variants were applied in genetic and pharmacological perturbation experiments to examine the Ca2+influx and clearance processes underlying the GCaMP signal. Distinct mutational and drug effects on GCaMP signals indicate differential roles of Na+and K+channels, encoded by genes includingparalytic(para),Shaker(Sh),Shab, andether-a-go-go(eag), in excitability control of different motor terminals. Moreover, the Ca2+handling properties reflected by the characteristic frequency dependence of the synaptic GCaMP signals were determined to a large extent by differential capacity of mitochondria-powered Ca2+clearance mechanisms. Simultaneous focal recordings of synaptic activities further revealed that GCaMPs were ineffective in tracking the rapid dynamics of Ca2+influx that triggers transmitter release, especially during low-frequency activities, but more adequately reflected cytosolic residual Ca2+accumulation, a major factor governing activity-dependent synaptic plasticity. These results highlight the vast range of GCaMP response patterns in functionally distinct synaptic types and provide relevant information for establishing basic guidelines for the physiological interpretations of presynaptic GCaMP signals from in situ imaging studies.
Encoding of the Intent to Drink Alcohol by the Prefrontal Cortex Is Blunted in Rats with a Family History of Excessive Drinking

Published: July 2019

AbstractThe prefrontal cortex (PFC) plays a central role in guiding decision making, and its function is altered by alcohol use and an individual’s innate risk for excessive alcohol drinking. The primary goal of this work was to determine how neural activity in the PFC guides the decision to drink. Towards this goal, the within-session changes in neural activity were measured from medial PFC (mPFC) of rats performing a drinking procedure that allowed them to consume or abstain from alcohol in a self-paced manner. Recordings were obtained from rats that either lacked or expressed an innate risk for excessive alcohol intake, Wistar or alcohol-preferring (P) rats, respectively. Wistar rats exhibited patterns of neural activity consistent with the intention to drink or abstain from drinking, whereas these patterns were blunted or absent in P rats. Collectively, these data indicate that neural activity patterns in mPFC associated with the intention to drink alcohol are influenced by innate risk for excessive alcohol drinking. This observation may indicate a lack of control over the decision to drink by this otherwise well-validated supervisory brain region.
Portuguese Origins of a 16th Century Aqueduct in México
Authors: Doolittle William E. 
Published: July 2019

Many aqueducts built during the Spanish colonial era remain standing in México, albeit not functioning. A few date to the 16th century. Some of these early aqueducts are quite spectacular and highly visible. Others are small and are located in places not easily found. Despite their size, small aqueducts are important for understanding knowledge pertaining to technology transfers from the Old World to the New. One such aqueduct is on the property of the Hacienda de Pacho, near Xalapa in the state of Veracruz. One of its highly unusual characteristics is that its construction involved Gothic arches. No other colonial aqueduct in México has such features. According to documentary courses dating to AD 1591, it was built by the hacienda’s original owner who was from the Portuguese island of Madeira. This paper reports on field activities involved in verifying the Maderian origins of this unique aqueduct.

Published: July 2019

CONTEXT:
Racial and ethnic disparities in health outcomes of newborns requiring care in the NICU setting have been reported. The contribution of NICU care to disparities in outcomes is unclear.

OBJECTIVE:
To conduct a systematic review of the literature documenting racial/ethnic disparities in quality of care for infants in the NICU setting.

DATA SOURCES:
Medline/PubMed, Scopus, Cumulative Index of Nursing and Allied Health, and Web of Science were searched until March 6, 2018, by using search queries organized around the following key concepts: “neonatal intensive care units,” “racial or ethnic disparities,” and “quality of care.”

STUDY SELECTION:
English language articles up to March 6, 2018, that were focused on racial and/or ethnic differences in the quality of NICU care were selected.

DATA EXTRACTION:
Two authors independently assessed eligibility, extracted data, and cross-checked results, with disagreements resolved by consensus. Information extracted focused on racial and/or ethnic disparities in quality of care and potential mechanism(s) for disparities.

RESULTS:
Initial search yielded 566 records, 470 of which were unique citations. Title and abstract review resulted in 382 records. Appraisal of the full text of the remaining 88 records, along with the addition of 5 citations from expert consult or review of bibliographies, resulted in 41 articles being included.

LIMITATIONS:
Quantitative meta-analysis was not possible because of study heterogeneity.

CONCLUSIONS:
Overall, this systematic review revealed complex racial and/or ethnic disparities in structure, process, and outcome measures, most often disadvantaging infants of color, especially African American infants. There are some exceptions to this pattern and each area merits its own analysis and discussion.

Published: July 2019

Amaç: Sezaryen ile doğum oranlarının artması adezyon formasyonu ilişkili komplikasyonlarda artışa neden olmaktadır. Morbidite ve mortalite ilişkili bu komplikasyonları preoperatif öngörebilmek, perinatal sonuçlarda belirgin iyileşme sağlayabilir. Çalışmanın amacı geçirilmiş sezaryen öyküsü olan olgularda skar özellikleri ile intraperitoneal adezyonlar arasındaki ilişkinin değerlendirilmesidir. Materyal ve metot: Prospektif olarak planlanan bu çalışmaya, üniversite hastanesinde, geçirilmiş sezaryen endikasyonu ile elektif sezaryen ile doğum yapacak ve dahil edilme kriterlerini karşılayan toplam 101 hasta dahil edilmiştir. Sezaryen skar özellikleri (pigmentasyon, cilt ile ilişkisi) preoperatif not edilmiştir. Takiben intraperitoneal adezyon varlığına göre hastalar iki gruba ayrılmış ve perinatal sonuçlar değerlendirilmiştir. Bulgular:Gruplar arasında yaş, vücut kitle indeksi (VKİ) ve gravida sayıları anlamlı fark izlenmemiştir (p&gt;0.05). İntraperitoneal adezyon olan hastalarda hiperpigmente skar varlığı anlamlı olarak daha yüksek bulunmuştur (%43 vs %15, p&lt;0.001). Çevre cilt ile skar ilişkisi eleve, aynı düzlemde ve deprese olarak sınıflandırıldığında, gruplar arasında skar yüksekliği açısından fark saptanmamıştır (p=0.21).Sonuç: Skar özelliklerinin değerlendirilmesi, sezaryen sonrası bağ doku iyileşmesini pratik ve objektif şekilde yansıtabilir. Ek olarak, bağ dokusu iyileşmesinin başka bir sonucu olan adezyon formasyonu gelişimini öngörmede etkili olabileceği düşünülmektedir. Özellikle pigmentasyon artışının preoperatif değerlendirilmesi ile batın içi yapışıklıklar hakkında bilgi sahibi olunabilir.

La detección temprana de los lectores con dificultad es fundamental para la implementación de programas de remediación.En Latinoamérica hay pocas herramientas para evaluar las habilidades prelectoras. La velocidad de denominación y la conciencia fonológica son considerados los principales predictores de la lectura. El objetivo de este trabajo fue adaptar al español la prueba RAN/RAS publicada por Wolf y Denkla (Wolf y Denkla, 2005) y determinar la correlación con las medidas de denominación con las de lectura entre preescolar y 3ro de la Escuela Primaria. Para ello se evaluó a 142 niños de entre 5 y 8 años en tareas de denominación, conciencia fonológica, segmentación fonémica, lectura de letras, lectura de palabras, lectura de pseudopalabras y comprensión de textos de acuerdo al año que cursaban. Los resultados obtenidos demuestran que la velocidad de denominación es un buen predictor de la lectura y que correlaciona con medidas de fluidez y precisión. Estos resultados confirman que su normalización en la población latinoamericana sería de gran utilidad para la detección temprana de niños en riesgo.

Published: July 2019

The cause of death among modern people are the highest death rate from heart disease and monitoring and management of ECG signals to cope with these heart diseases is necessary. ECG is a bio-signal that is an important criterion for determining the presence or absence of cardiac activity states. Recently, an attempt has been made to analyze and compare biological signals and physical activity information for accurate analysis and diagnosis. However, in order to measure the ECG data for a long time, a storage space of several Mbytes and a wide bandwidth for wireless transmission are required. To solve this problem, cost, time, and high-performance systems are additional required. The implemented system minimizes the amount of packets generated during wireless data transmission as well as abnormal heartbeat detection and activity information, and enables monitoring of heart activity status and activity information in real time through a smart phone. In order to evaluate the data packet transmission and restoration performance of the system implemented in this research, the MIT / BIH Arrhythmia Database 100 record was embedded in the system controller section and the packet was transmitted to the smartphone. In addition, ECG evaluation experiments were conducted according to the activity status during daily life. As a result of the performance evaluation, both experiments confirmed the data packet generated and signal restoration performance.

Published: July 2019

The problem of mining a high dimensional data includes a high computational cost, a high dimensional dataset composed of thousands of attribute and or instances. The efficiency of an algorithm, specifically, its speed is oftentimes sacrificed when this kind of dataset is supplied to the algorithm. Fuzzy C-Means algorithm is one which suffers from this problem. This clustering algorithm requires high computational resources as it processes whether low or high dimensional data. Netflix data rating, small round blue cell tumors (SRBCTs) and Colon Cancer (52,308, and 2,000 of attributes and 1500, 83 and 62 of instances respectively) dataset were identified as a high dimensional dataset. As such, the Manhattan distance measure employing the trigonometric function was used to enhance the fuzzy c-means algorithm. Results show an increase on the efficiency of processing large amount of data using the Netflix ,Colon cancer and SRCBT an (39,296, 38,952 and 85,774 milliseconds to complete the different clusters, respectively) average of 54,674 milliseconds while Manhattan distance measure took an average of (36,858, 36,501 and 82,86 milliseconds, respectively) 52,703 milliseconds for the entire dataset to cluster. On the other hand, the enhanced Manhattan distance measure took (33,216, 32,368 and 81,125 milliseconds, respectively) 48,903 seconds on clustering the datasets. Given the said result, the enhanced Manhattan distance measure is 11% more efficient compared to Euclidean distance measure and 7% more efficient than the Manhattan distance measure respectively.

Published: July 2019

Failure detection systems have become important not only in production processes, but nowadays there is a need for their implementation in various daily areas, for example, for the detection of physical damages that a car may present in a parking lot, in order to provide to the client with the assurance that their personal property will not be affected inside the lot. This paper presents an algorithm based on convolutional neural networks and a variant of these using regions (CNN and R-CNN), which allows to detect scratches in a car. In the first instance, the capture of one of the sides of a conventional car is done, an R-CNN is designed to extract only the region of the image where the car is located. After this procedure, the extracted region is divided into multiple sections, and each of the sections is evaluated in a CNN to detect in which parts of the vehicle the scratches are located. With the test images, a precision percentage of 98.3% is obtained in the R-CNN, and 96.89% in the CNN, demonstrating in this way the robustness of the Deep Learning techniques implemented in the detection of car scratches. The processing times of each one of the algorithm stages corresponding to the R-CNN and the classification of the sections in the CNN were 1.6563 and 1.264 seconds respectively.

Published: July 2019

In general potato suitable cultivated in the highland area, the reasoning is in this altitude area the tuber’s growth of potato in which provides the optimum climatic condition. Vegetable such as potato is growth at any time of the year, depending upon the availability of water or irrigation water. The farmers also the cultivation of potato in medium altitude area due to the availability of the area is limited. Therefore cultivation of tubers in medium altitude area is investigated. Potato Eigenheimer cultivars and Granola cultivars were planted at a medium altitude area of 754 m above sea level; in research station of campus Universitas Padjadjaran west Java Indonesia. The average temperature was 23°C. The treatments were three intervals of irrigation every two days (A1), four days (A2) and six days (A3); and the treatments were applied three of potassium fertilizer (KCL dosage: 50 (P1), 100 (P2) and 150 (P3) (kg/ha) which three levels of nitrogen. The result shows that two days of irrigation intervals (A1) and 100 kg/ha potassium (P2) obtain the highest essential amino acids concentration of Granola cultivar if compared with Eigenheimer cultivar. The interaction between the application of interval irrigation and potassium fertilizer effects to a mineral such as calcium and iron content in the tuber. While the content of both mineral is higher in Granola cultivar than that in Eigenheimer cultivar.
