Explore Better Relative Position Embeddings from Encoding Perspective for Transformer Models

Relative position embedding (RPE) is a successful method to explicitly and efficaciously encode position information into Transformer models. In this paper, we investigate the potential problems in Shaw-RPE and XL-RPE, which are the most representative and prevalent RPEs, and propose two novel RPEs called Low-level Fine-grained High-level Coarse-grained (LFHC) RPE and Gaussian Cumulative Distribution Function (GCDF) RPE. LFHC-RPE is an improvement of Shaw-RPE, which enhances the perception ability at medium and long relative positions. GCDF-RPE utilizes the excellent properties of the Gaussian function to amend the prior encoding mechanism in XL-RPE. Experimental results on nine authoritative datasets demonstrate the effectiveness of our methods empirically. Furthermore, GCDF-RPE achieves the best overall performance among five different RPEs.

Modeling Graph Structure via Relative Position for Text Generation from Knowledge Graphs

We present Graformer, a novel Transformer-based encoder-decoder architecture for graph-to-text generation. With our novel graph self-attention, the encoding of a node relies on all nodes in the input graph - not only direct neighbors - facilitating the detection of global patterns. We represent the relation between two nodes as the length of the shortest path between them. Graformer learns to weight these node-node relations differently for different attention heads, thus virtually learning differently connected views of the input graph. We evaluate Graformer on two popular graph-to-text generation benchmarks, AGENDA and WebNLG, where it achieves strong performance while using many fewer parameters than other approaches.

Identification some species of syrphids flies (Diptera: Syrphidae) in Lattakia region

This study was conducted during the period from 10/9/2016 to 9/9/2017 in Demsarkho orchards area (Lattakia) on the west coast of Syrian Arab Republic. The study aimed to identificate "Syrphidae" in this area. Samples were collected by yellow dishes in weekly rate. A total of 341 Syrphid flies were collected and they belong to 15 species form 10 genera. The most abundant species was Sphaerophoria scripta (relative abundance 33.43%), followed by Episyrphus balteatus (20.53%), then Melanostoma mellinum (14.66%).

Study of service levels in Lattakia International Container Terminal LICT

Container transportation is one of the essential elements of modern ren aissance in shipping business in the world. Due to its extremely important, most countries have focused (especially the developed ones) on development of their maritime fleets and ports, in order to be able to keep up and keep the remarkable development and extremely rapid progress in containerization technology. Port capabilities should be commensurate with the developments in maritime transport fleets and their transport patterns represented by container vessels that require advanced port services such as high efficiency of workers and cranes, and modern and fast performance specialized equipments, and modern electronic systems. The study addressed the basic criteria for the level of services in the container terminals that have been identified in the United Nations Conference on Trade and Development UNICTAD 2012, These criteria were applied to Lattakia International Container Terminal (LICT), where the relative waiting time ε and productivity coefficient (P) were calculated for the duration of the ship's stay in the port, and the statistical indicators of the times of ships at the Lattakia International Container Terminal and the container handling rates was studied during the period Extending from 2014 to 2017, The study concluded that the average wait time relative ε achieved the value of 0.0553, which put it at level B which is the second level of four levels, A, B, C, D, in addition to the level B is also achieved by productivity coefficient (P) and the value of 54.4 during the The study period.

Competitiveness of Syrian Apple Exports

The aim of this research was to analyze the current structure of Syrian apple exports, and highlighting the relative advantage of this crop and its competitive position on the markets of the key importing countries of Syrian apples. The analysis was based on secondary data published by FAO during 2000-2013. Descriptive statistical analyses were used, in addition to estimates of time trend equations to identify the evolution in quantity, value and price of both Syrian apple exports and imports, and to determine certain indicators of export competitiveness, besides to applicate the linear programming model for optimal distribution of Syrian apple exports.

Evaluation of active tectonics in the northern part of coastal area in Syria using geomorphic indices and drainage analysis derived from a digital elevation model (DEM)

The research aims to evaluate active tectonics using DEM derived drainage network and geomorphic indices: streamlength gradient (SL), hypsometric integral (HI), basin shape index (Bs), mountain front sinuosity (Smf), and fractal dimension (FD).

Study of foraminifera's relative changes and lithology of coast sand in Ra’as Shimra-Lattakia

A microscopic study was done on five samples from the current beach sand at Ra’asShimra beach in order to identify their Foraminifera content and the abundance of the species relative to each other. The micropaleontology analysis showed that the majority of the 17 specified types live on the bottom in shallow marine waters at moderate to hot temperatures. The abundance of the species was noticed in the benthic species such as: Amphistegina, Textularia, and peneroplis, which indicates the availability of suitable environmental conditions for the prosperity of these species, which is close to the current conditions. The samples of sand studied are characterized by their being disjointed, small to medium in size, varying in color, and rich in organic remains, mainly the remains of molluscs, in addition to oval marine-originated stones that vary in size. The X.R.D analysis showed the presence of two phases: a major calcareous phase, and a secondary quartz phase. The study of the thin rock slides taken from rocks located in the region, which can be considered as the source rocks of sand in the study area, showed that it is a sandy limestone.

An Analytical Study of the Economics Of Water Resources

This research aims to shed a light on the distinctive economic characteristics of water resources and to identify the reasons that led to increasing interest in studying these resources and their economics. depending on descriptive analytical method through characterization of what is and analyze it, The researcher is addressing the policies necessary to be followed for a successful allocation of water balances within the time periods, and define whether the water resources are to be considered as an economical good and whether they are subjected to market mechanisms, i.e. demand and supply. the research results pointed out to the fact that the water resource is a strategic vital resource and an economic good has a special nature which make it not subject to market mechanisms. this study is providing a number of proposals that emphasize the need to focus on the economics of water resources to attain the efficiency of resource exploitation, which, on the one hand, leads to achieving sustainability of this valuable resource, and on the other hand fulfill maintain the economic development.

Comparison of Dissolution Time of Sodium Ceftriaxone Preparations for Injection and Studying the Factors Affecting it

The aim of this study is to compare the dissolution time of six formulations of paranteralSodium Ceftriaxonepreparation, the original product and five generic local ones. The dissolution time was measured precisely as the point at which the dried powder of Sodium Ceftriaxone preparation became a transparent solution on the addition of physiologicalsolution 0,9% of Sodium Chloride. The dissolution time of the six products were different. The measurement of infrared spectroscopy (FTIR) of different powder preparations was conducted, then the weight, the humidity and the morphology of different medical powders were studied to investigate the factors influencing the dissolution time. The difference in dissolution time between the six products was due to differences in powder characteristics such as water content, crystal shape and dimension. It was shown that one local generic product of Sodium Ceftriaxone islook like the original one.
