This study attempts to investigate the effect of oil returns and external debt on the government expenditure in Syria over the period 1970-2010. The Johansen cointegration test showed that oil returns and external debt have a positive and significant long run relationship with government expenditure. The Granger causality test indicates unidirectional short-run causality relationships running f...

Delamination of the veneering composite is frequently encountered with fibre-reinforced composite (FRC) fixed dental prosthesis (FDPs). The aim of this study is to evaluate the influence of framework design on the load-bearing capacity of laboratory-made three-unit inlay-retained FRC-FDPs. Inlay-retained FRC-FDPs replacing a lower first molar were constructed. Seven framework designs were evalu...

In this paper, we carry out two experiments on the TIMIT speech corpus with bidirectional and unidirectional Long Short Term Memory (LSTM) networks. In the first experiment (framewise phoneme classification) we find that bidirectional LSTM outperforms both unidirectional LSTM and conventional Recurrent Neural Networks (RNNs). In the second (phoneme recognition) we find that a hybrid BLSTM-HMM s...

In heterogeneous ad hoc networks, high-power nodes could potentially interfere with any on-going transmissions of low-power nodes. In this paper, we propose a unidirectional-link aware MAC protocol (UAMAC) which prevents such an interference problem by reserving the wireless channel of unidirectional high-power node selectively over one-hop. Our preliminary performance results show that the UAM...

This paper considers satellite unidirectional links having a large number of nodes and discusses the PIM-SM configuration on these links if there is no separate multicast routing information base. Looking closely at the PIM-SM specification documents, we propose a PIM-SM configuration that enables multicast traffic to flow on unidirectional links. We also discuss the scalability of PIM-SM on sa...

The prediction of ionic currents in protein channels of biological membranes is one of the central problems of computational molecular biophysics. Existing continuum descriptions of ionic permeation fail to capture the rich phenomenology of the permeation process, so it is therefore necessary to resort to particle simulations. Brownian dynamics (BD) simulations require the connection of a small...

The delivery of intensity-modulated radiation therapy (IMRT) with a multileaf collimator (MLC) requires the conversion of a radiation fluence map into a leaf sequence file that controls the movement of the MLC during radiation delivery. It is imperative that the fluence map delivered using the leaf sequence file is as close as possible to the fluence map generated by the dose optimization algor...

In this work, two different catenane based molecular motors were reviewed. These motor molecules consist of two interlocked rings, one of which has binding sites for the other ring. The smaller ring without the binding sites can rotate over the other macrocycle when the affinities of the binding sites are changed. If the rotation is unidirectional the molecule could in principle perform work. I...

Combining ideas from Donald Davidson, Hans Reichenbach and Discourse Representation Theory (DRT), I will develop a constraint-based semantics for the Dutch tenses and temporal auxiliaries which is fully integrated in the HPSG framework. The semantics will be inspired to a large extent by DRT, but the syntax is squarely based on the lexicialist surface-oriented approach of HPSG, and so is the tr...

We demonstrate unidirectional bistability in microdisk lasers electrically pumped and heterogeneously integrated on SOI. The lasers operate in continuous wave regime at room temperature and are single mode. Integrating a passive distributed Bragg reflector (DBR) on the waveguide to which the microdisk is coupled feeds laser emission back into the laser cavity. This introduces an extra unidirect...
