Relation-Dependent Sampling for Multi-Relational Link Prediction

Multi-relational graphs specifically allow for representing different types of relations and are an effective way to model various types of data including social networks (Balakrishnan & T. V., 2020), knowledge graphs (Vrandečić & Krötzsch, 2014), and biomedical networks, such as interactions between molecules (Krogan et al., 2006). Link prediction (Zhang & Chen, 2018) in these graphs is an actively studied problem that is critical for many applications. For example, drug-drug interaction (DDI) prediction is a task important for drug development and repurposing: on the one hand, some diseases are best treated by combinations of drugs (e.g., antiviral drugs are typically administered as cocktails), on the other hand, one has to know about critical side effects between new molecules and existing drugs (in a stricter sense, side effects are consequences of DDIs).
REP18 Atlantic – A Large Scale Exercise Using Unmanned Systems, Field Report

We describe the 2018 edition of the Recognised Environmental Picture exercise (REP18). Every year, the Portuguese Navy hosts an international exercise where challenging and novel operational scenarios are tested in a controlled environment. This is done to achieve a readiness level that allows the use of those developments in future real-world scenarios. The objectives range from military to different scientific purposes, always aiming for the use of innovative though operational technologies. In this paper we document the 2018 objectives and results, as well as innovations that helped resolving the challenges posed by this operational environment enriched by multiple heterogeneous vehicles.
Mechanical Properties and absorption behavior of CSP Filled Roselle Fiber Reinforced Hybrid Composites

This article depicts the mechanical properties and hydrophilic behavior of a new class of multi-phase composites consisting of vinyl ester resin reinforced with Roselle fiber and filled with coconut shell particulates (CSP). Fiber reinforced Vinyl ester composites was prepared by incorporating coconut shell at four different filler contents viz. 0%, 5%, 10%, and 15%. The mechanical properties of these composites are evaluated. The results show that the tensile and impact strength of the composite increase with increase in coconut shell content, the flexural strength of the composite is a maximum of at 5% of the CSP filler content. The water absorption goes on increasing with increase of time duration and CSP filler content. The maximum of water absorption is obtained from the composite prepared with 15% CSP filler. The hardness and density of the composites are also greatly influenced by the content of these fillers.
Effects of vitamin C and vitamin E on performance, digestion of nutrients and carcass characteristics of Japanese quails reared under chronic heat stress (34 °C)

: This study was conducted to determine the effects of vitamin C (L-ascorbic acid) and vitamin E (DL-alpha-Tocopheryl acetate) on performance, digestion of nutrients and carcass characteristics of Japanese quails reared under chronic heat stress (34 degrees C). A total of 180 10-day-old Japanese quails were randomly assigned to six treatment groups, three replicates of 10 birds each. The birds with a 2 x 3 factorial design received either two levels of vitamin C (100 and 200 mg/kg of diet) or three levels of vitamin E (125, 250, or 500 mg/kg of diet). Then, 200-mg vitamin C/kg of diet, compared with that of 100 mg/kg of diet, and higher dietary vitamin E inclusions resulted in a higher performance. The interaction between vitamin C and vitamin E for final body weight change (p=0.01) and feed efficiency (p=0.02) was detected. Final body weight change and feed efficiency increased to a higher extent by increasing dietary vitamin C when higher vitamin E levels were fed. Carcass characteristics improved with an increase of both dietary vitamin C and vitamin E (p=0.004). The interactions on carcass characteristics were all significant (p=0.02) and manifested themselves in a way that they were improved to a higher extent by an increase of dietary vitamin C when higher vitamin E levels were fed. Digestibility of nutrients (DM, OM, CP and EE) was greater with higher dietary vitamin C (p < 0.02) and also with higher vitamin E (p=0.07). There were no interactions detected for digestibility of nutrients (p=0.32). Taken together, the results of the present study conclude that a combination of 200 mg of vitamin C and 250 mg of vitamin E provides the greatest performance in Japanese quails reared under heat stress and can be considered as a protective management practice in poultry diet, alleviating the negative effects of heat stress.
A tree‐ring reconstruction of wind disturbances in a forest of the Slovakian Tatra Mountains, Western Carpathians

Question: Have past windstorm events influenced the structure and composition of mountain forests in the Tatra Mountains? Can severe and infrequent wind disturbances lead to dynamic coexistence of two tree species with different ecological requirements? Location: Subalpine mixed spruce-larch forest at 1200-1300 m a.s. l. in the Slovakian Tatra Mountains. A forested site affected by catastrophic large-scale windthrow on 19 November 2004. Methods: Sixty-seven spruce and 30 larch cross-sections from the oldest cohorts were collected in a regular pattern in a 100-ha plot. Tree-ring series were analysed to reconstruct growth releases associated with past windthrows. A boundary-line release criterion was applied to detect disturbance year. Spatial patterns of release signals were statistically detected with Mantel's test. We compared reconstructed years of disturbance events with historical records. Results: Releases in both species showed three main pulses. More than 85% showed major or moderate releases in 1865-1879, 48% in 1915-1924, and 25% in 1940-1949. All of these disturbance events affected the whole 100-ha area. Releases were spatially patterned in the first disturbances, but distributed randomly in the last. Releases co-occurred in time with enhanced production of compression wood, suggesting disturbances were of wind origin. Reconstructed dates of windthrows were confirmed using historical data on storms. Conclusions: At least three windthrows of major and moderate severity took place in the last 150 years on southern slopes of the Tatra Mountains. This disturbance regime may contribute to coexistence of spruce and larch through differences in vulnerability and response to heavy windstorms.
Time of flight simulation and reconstruction in Hybrid MR-PET Systems

In traditional PET, coincidence electronics are used to determine the line of response along which an annihilation has occurred. With time-of-flight(TOF), the approximate position of the annihilation along the line of annihilation is calculated by measuring the difference between the arrival time of the photons in the detectors. In the literature, TOF images show (in general) a lower level of noise and better resolution compared to non-TOF images. The lower noise and amplified sensitivity of TOF reconstruction could favour a better use of the full resolution potential of PET scanners. The first part of this thesis focuses on the possibility of using faster simulating methods, more specifically, the possibility of replacing the time consuming GATE simulations by a script (from Paola Solevi from Otto-von-Guericke-Universität Magdeburg) was studied. The results show that the values obtained in the simulations with the Hoffman Brain Phantom are very similar between the two methods, showing the viability of this script with this phantom. Then, the same procedure was performed using a Voxelized Brain Phantom. This time the results were different from the ones obtained before because the values obtained with the two methods are very different. Therefore, it is important to know if there is some kind of problem with the phantom used that origins those results or if the problem comes from the script. The second part of this thesis focuses on the development of reconstruction procedures for simulations done with the GE Signa PET-MR scanner. The methods includes the simulation of three phantoms (offcenter cylinder and Hoffman Brain Phantom to reconstruct and a large cylinder for the normalisation), a coordinates algorithm developed in MATLAB that can calculate the correct coordinates, for the sinograms, from the GATE coordinate output and a method that, from an uncorrected sinogram, obtains an arc corrected sinogram that can be used in reconstructions. The results show that the reconstructions were successful, without any artifacts. The reconstructions done without each one of the corrections, show artifacts in both phantoms. These results show the importance of doing corrections before reconstructing the data. Key-words: PET-MR, BrainPET, GE Signa, TOF, GATE
Variation of carbon and nitrogen cycling processes along a topographic gradient in a central Amazonian forest

It is well recognized in the literature that topography can influence soil nutrient stocks and dynamics in temperate regions, but for tropical forests, this source of variation has sometimes been ignored. The nature of such variations may depend upon the soil type, which in turn, is closely linked to local or regional topography. This study characterizes the soil and describes the status of carbon and nitrogen in vegetation, litterfall, litter‐layer and soil upper layers along the main positions of a topographic gradient (plateau, slope and valley), 60 km north of Manaus, on Cuieiras Reserve watershed. Nitrogen concentrations in living leaves, fresh litterfall, litter‐layer and soil upper layers were lower in the valley than in both slope and plateau plots. Carbon concentrations in plant material were not significantly different among the three topographic positions, resulting in higher C : N ratios in valley plots. Local topography (plateau, slope and valley) clearly was an influential factor in the nutrient distribution along the study locations. Lower rates of N cycling processes in the valley are probably related to its sandy soil texture and seasonal flooding.

539. The effect of temperature treatment of cream before churning on the consistency of butter

1. Measurements of hardness and ‘free-oil’ content of samples of butter from cream held at various temperatures before churning were made before and after storage. Hardness was determined by the sectility method, while free-oil content was estimated from the weight of oil exuding from thin slices of butter sandwiched between filter-papers and held at 64–4° F. (18° C). 2. Butter from cream held at 60° F. and churned at 45° F. was much softer and contained more free oil than butter from cream held and churned at 45° F. 3. If the cream was precooled to 45° F. before being held at 60° F. the butter was very slightly softer than that from cream held at 60° F. without precooling, but the difference disappeared after storage. It contained rather less free oil, but the softening point of the oil was lower. Fat losses in churning which were high where cream was held at 60° F. were reduced almost to normal when cream was precooled before being held at 60° F. 4. Cream slowly cooled to 45° F. yielded butter which was softer and contained more free oil than that from cream cooled rapidly to 45° F. and held at that temperature. The butter, however, was not so soft as that from cream held at 60° F. 5. Butter from cream held at a temperature below that at which it was to be churned did not differ significantly in hardness or free-oil content from that produced from cream held at the churning temperature. 6. Present commercial methods of cream treatment in New Zealand (rapid cooling to churning temperature and holding at that temperature) give butter of almost maximum hardness for the type of fat involved at each stage of the season. 7. More uniform consistency of butter throughout the season could be achieved only by reducing the hardness of the firmer butter and not by increasing the firmness of the ofter butter.
A Study on High Precision MEMS-IMU/GPS/Magnetometer/Barometer Integrated Navigation System

Considering the urgent need of low cost, high performance and high precision navigation system, a MEMS-IMU / GPS / magnetometer / barometer integrated navigation system based on DSP is designed. Using the output of MEMS-IMU, we can obtain the carrier's attitude, velocity and position with SINS algorithm. We use a barometer to dampen the inertial altitude path. Then combined with the information of GPS and magnetometer, an integrated navigation algorithm based on Kalman filter is designed, We conduct static and dynamic experiments on the integrated navigation system and the results show that the system can achieve high navigation accuracy.
A word-building method based on neural network for text classification

ABSTRACT Text classification is a foundational task in many natural language processing applications. All traditional text classifiers take words as the basic units and conduct the pre-training process (like word2vec) to directly generate word vectors at the first step. However, none of them have considered the information contained in word structure which is proved to be helpful for text classification. In this paper, we propose a word-building method based on neural network model that can decompose a Chinese word to a sequence of radicals and learn structure information from these radical level features which is a key difference from the existing models. Then, the convolutional neural network is applied to extract structure information of words from radical sequence to generate a word vector, and the long short-term memory is applied to generate the sentence vector for the prediction purpose. The experimental results show that our model outperforms other existing models on Chinese dataset. Our model is also applicable to English as well where an English word can be decomposed down to character level, which demonstrates the excellent generalisation ability of our model. The experimental results have proved that our model also outperforms others on English dataset.
Distribution and chromatic adaptation of phytoplankton within a shelf sea thermocline

Observations of vertical gradients in phytoplankton community structure were made through the water column of the seasonally stratified Celtic Sea, including within the thermocline. A deep chlorophyll maximum (DCM) was located within the thermocline at all stations, coupled to the nitracline. Vertical gradients in phytoplankton community composition were routinely observed within the thermocline. The cell abundance maxima for Synechococcus occurred in the upper part of the DCM coincident with a picoeukaryote abundance minima. Picoeukaryote abundance typically increased at or just above the peak of the DCM. Diatoms were observed occasionally at the DCM peak. Pigment compositions and phytoplankton absorption spectra indicated that the different phytoplankton communities were chromatically well adapted to the spectral composition of irradiance at the depths where they occurred in the water column. Profiles of vertical eddy diffusivity revealed that timescales formixing between the phytoplankton layers within the thermocline were in excess of typical phytoplankton growth rates. The observed vertical gradients in community structure could therefore result from selection and niche partitioning of phytoplankton types on the light and nutrient gradient within the thermocline. The data further indicate that the pigments, light absorption characteristics, and cell size contribute to the phytoplankton selection process.
Investigation of a Rectenna element for infrared and millimeter wave application

This thesis presents the rectifying antenna potential for infrared and millimeter wave energy conversion. Infrared imaging is one of the emerging technologies that have attracted considerable attention in the next generation of military, medical, and commercial applications. Moreover, with the ever-increasing congestion of the electromagnetic spectrum at RF and microwave frequencies and the establishment of firm civilian and military requirements best met by millimeter wave systems, the interest in the technology has grown and is now firmly established. During this work a 2.5GHz slot antenna, a 2.5GHz Schottky diode detector, a CPW-to-Microstrip transition, a fully integrated Rectenna element, and a 94GHz slot antenna were designed, fabricated, and tested. Results on the performance of the devices show a great deal of correlation between the simulated and measured data. To perform an initial study, the CPW-fed narrow slot antenna is designed at 2.5GHz and implemented on an FR-4 board. This investigation serves as the basis for the development of the Rectenna element at millimeter wave frequencies. In order to increase the bandwidth of the slot antenna, a 2.5GHz CPW-fed wide slot antenna with U-shaped tuning stub is realized, which provides a 60% increase in bandwidth while keeping the same radiation characteristics. In addition, a set of simulations is performed to show how
Prop‐2‐ynyl 3‐(3,4‐di­hydroxy­phenyl)­prop‐2‐enoate monohydrate

Crystals of the title compound, C12H10O4·H2O, were obtained from the Knoevenagel condensation reaction of 3,4-di­hydroxy­benz­aldehyde and monoprop-2-ynyl malonate. The almost planar mol­ecule is the E isomer. There are intermolecular O—H⋯O and C—H⋯O hydrogen bonds and π–π interactions, which contribute to the formation of the crystal structure.
Identification of genomic regions carrying QTL for agronomic and quality traits in rye (Secale cereale) introgression libraries.

Introgression libraries can be used to localize genomic regions carrying quantitative trait loci (QTL). We used this approach to detect QTL regions affecting the per se performance of agronomic and quality traits with two rye (Secale cereale L.) introgression libraries. Our objectives were to detect candidate introgression lines (pre-ILs) that have a different per se performance than the recurrent parent and to identify the underlying QTL regions. The introgression libraries containing 40 BC 2 S 3 lines each were established with marker-assisted backcrossing from crosses of the heterozygous Iranian primitive rye accession Altevogt 14160 and the elite inbred line L2053-N. To assess the phenotypic effect of the donor chromosome segments (DCS) the pre-ILs were evaluated for grain yield, plant height, thousand-kernel weight, test weight, falling number and protein content in replicated field trials at five locations in Germany over 2 years. In total, 58 significant (P < 0.05) differences between pre-ILs and L2053-N were observed in each introgression library. The DCS in pre-ILs differing from the recurrent parent possess most likely the responsible QTL. Genomic regions carrying favourable QTL alleles were detected for test weight, thousand-kernel weight and protein content. We conclude that Altevogt 14160 can not only be used to enrich the genetic variation of the restricted hybrid rye gene pools but will also allow the breeder to efficiently detect favourable QTL for marker-assisted selection.
A cardiac arrhythmia monitoring platform based on feature selection and classification methods

Heart arrhythmia, also known as irregular heartbeat, affects millions of people around the world. One of the ways to detect this cardiac dysrhythmia is by performing an electrocardiogram (ECG) exam which records the electrical activity of the heart. However, this type of exam is always interpreted by a doctor. In order to provide an alternative in heart arrhythmia diagnosis, this paper aims at developing a platform based on Internet of Things infrastructure capable of automatically monitoring and identifying cardiac arrhythmia based on feature selection and classification methods.
Securing Cluster-heads in Wireless Sensor Networks by a Hybrid Intrusion Detection System Based on Data Mining

Cluster-based Wireless Sensor Network (CWSN) is a kind of WSNs that because of avoiding long distance communications, preserve the energy of nodes and so is attractive for related applications. The criticality of most applications of WSNs and also their unattended nature, makes sensor nodes often susceptible to many types of attacks. Based on this fact, it is clear that cluster heads (CHs) are the most attacked targets by attackers, And also according to their critical operations in CWSNs, their compromise and control by an attacker will disrupt the entire cluster and sometimes the entire network, so their security needs more attentiveness and must be ensured. In this paper, we introduce a hybrid Intrusion Detection System (HIDS) for securing CHs, to take advantages of both anomaly-based and misuse-based detection methods, that is high detection and low false alarm rate. Also by using a novel preprocessing model, significantly reduces the computational and memory complexities of the proposed IDS, and finally allows the use of the clustering algorithms for it. The simulation results show that the proposed IDS in comparison to existing works, which often have high computational and memory complexities, can be as an effective and lightweight IDS for securing CHs.
Heritability of performance test traits in Chianina, Marchigiana and Romagnola breeds

Abstract Performance testing is the main method of selection used for Marchigiana, Chianina and Romagnola breed since 1985. The young bulls are tested in a common central station for 6 months period, starting from the age of about 6 months. The bull selection is carried out accounting for genetic indexes of average daily gain (ADG) measured till weaning (PAGD), ADG realized during the test (TADG) and fleshiness (FLESH) measured at the end of test. Data of 2422 young bulls (735 Marchigiana, 863 Chianina and 824 Romagnola) were used to update estimates of heritability for performance test traits of aforementioned Italian beef cattle breeds. For traits measured till weaning (PADG), heritability differed among breeds from very low values for Marchigiana (0.02) to moderate for Romagnola (0.20), while for TADG, h2 estimates were more similar among breeds, ranging from 0.28 to 0.34. Similarly, h2 values obtained for FLESH trait were higher than values obtained till to weaning, but more variable among breed than TADG, i.e. from 0.19 to 0.55.
Ultrasound guided 4 in 1 block for managing postoperative pain in arthroscopic knee surgery

Surgeries of the knee are usually painful and managing postoperative pain is challenging. Various methods of analgesia are available. Epidural is considered as gold standard but after the advent of ultrasound, peripheral nerve blockade of the lower limb is gaining importance. A 50-year-old male patient posted for arthroscopic knee surgery, completed under spinal anaesthesia, was given four in one block using ultrasound. The point of entry of the needle was in lower thigh where the femoral artery dips down deep. 30ml of 0.25% bupivacaine was given in the space above it. Postoperatively, the time of first systemic analgesia was noted which was eight hours after full regression from spinal. Peripheral nerve blocks of the lower limb for knee surgeries usually target only the femoral component. Addressing the sciatic component with a single injection is a real challenge and we did it to block the four nerves with a single point injection. We conclude 4 in 1 block is useful as a postoperative analgesic technique in knee surgeries.
