In this article, we propose the fractional weak adversarial networks (f-WANs) for the stationary fractional advection dispersion equations (FADE) based on their weak formulas. This enables us to handle less regular solutions for the fractional equations. To handle the non-local property of the fractional derivatives, convolutional layers and special loss functions are introduced in this neural network. Numerical experiments for both smooth and less regular solutions show the validity of f-WANs.

This paper highlights the effects brought about by the implementation of the Information Communication Technology (ICT) subject in the Zambian primary education curriculum, in Chawama’s, Twatasha and Chimwemwe public primary schools in Lusaka district. This paper used qualitative research design. The three public primary schools of Chawama township in Lusaka district were targeted and were mainly the focus of this study. Both convenience and non-probability sampling techniques were employed. Three research instruments were used in collecting data, namely: semi- structured interviews, focus group interviews, observations and document digging. Data was transcribed, summarized, categorized and interpreted accordingly. Our paper will contribute to the literature within this subject area and will help future researchers to gain insight of the on goings of these issues.

In addition to causing myiasis in humans, Megaselia spiracularis Schmitz has also been reported as a forensically important fly. In this study, we presented the morphology of all larval instars and puparium of M. spiracularis using scanning electron microscopy. The first instar larva was composed of 12 segments. Antennae and maxillary palp complex were visible. Two spiracular slits could be seen at the posterior spiracle. The branch of posterior spiracular hairs was approximately equal to the palm-formed base in length. Second and third larval instars were very similar to first instar, except for the presence of anterior spiracle. The labium of the second instar larva was triangular and ventrally curved, whereas it was a bilobed structure and the tip forked in the first instar. The bubble membrance comprised of ≈40 globules presented at the third instar larvae. Puparia showed a retracted cephalic region and a pair of pupal respiratory horns on the dorsum. A comparison of the morphological features between immature stages of M. spiracularis and M. scalaris, a forensically important fly indoors in Germany, Malaysia, and China, was discussed.

The aim of this study was to prospectively evaluate and compare the effects of radiofrequency thermocoagulation of the first division branches of the trigeminal nerve (trigeminal peripheral division radiofrequency thermocoagulation, PRT) versus conventional radiofrequency (CRF) in the treatment of first division idiopathic trigeminal neuralgia (ITN). Fifty patients with first division ITN were randomly divided into two groups. The 20 patients in group 1 were treated with CRF, while the remaining 30 patients in group 2 were treated using PRT. The immediate therapeutic effects, side effects and recurrence rate of idiopathic trigeminal neuralgia were evaluated. The immediate efficacy rates were 95% and 93% in groups 1 and 2, respectively. The recurrence rates of ITN at the 3-year follow-up were 25% and 27% for group 1 and group 2, respectively, and 35% and 40%, respectively, 5 years after treatment. There were no significant differences between groups 1 and 2 at any time. Our study demonstrates that PRT is an effective way to treat first division ITN.

Measuring the performance of supply chain is a difficult task. The purpose of this paper is to provide a dynamic appraisal model for supply chain performance based on extension theory. The appraisal system of supply chain performance is represented by matter-element method and extension analysis in extension theory. The dynamic appraisal model for supply chain performance based on extension theory is created. Range of index value is depicted by classic region and segment region, relation function is used to do level appraisal. At last the feasibleness and maneuverability of model is verified by experiments. The model has the character of reflecting supply chain dynamically operation.

We have successfully prepared the iron-based superconductor K0.8Fe2Se2 crystals (Tc=27 K) and studied the carrier transport properties along the c-axis in detail. Samples are characterized by XRD, SEM and temperature-dependent resistivity. The result shows that there is “phase separation” in the samples. Based on the experimental results, the iron-based superconductor is not a simple two phases alternating along the c-axis, but the metal phases should have weak-link channels along the c-axis, forming a nearly 3D special net mode. Studies of the thermal conductivity and the complex impedance spectrum z(omega, T0) suggest that the superconducting crystals have a lot of grain boundaries along the c-axis direction, the bound polarization charges result in relative dielectric constant of about 106 in magnitude and negative phase characteristics in the vicinity of 10 MHz.
