This communication presents the design and implementation of a beam steerable leaky wave antenna (LWA) based on integrated electronic devices (varactor diodes). The uses half-mode substrate-integrated waveguide (HMSIW) where short-circuited wall or PEC boundary is realized with field programmable microwave substrate (FPMS)-based unit cells. By virtue placing varactor diodes in these cells, wave...

Seven new formyl phloroglucinol meroterpenoids (FPMs), namely eucalrobusones J-P (1-7), as well as three known ones (8-10) were isolated from the leaves of Eucalyptus robusta. Their structures were elucidated by spectroscopic data analysis, and their absolute configurations were determined by applications of the Snatzke's helicity rule and the electron circular dichroism (ECD) calculation. Thes...

Approximate algorithms for structured prediction problems—such as the popular αexpansion algorithm (Boykov et al. 2001) in computer vision—typically far exceed their theoretical performance guarantees on realworld instances. These algorithms often find solutions that are very close to optimal. The goal of this paper is to partially explain the performance of α-expansion on MAP inference in Ferr...

The flexure parallel mechanism (FPM) possessing selective actuation (SA) feature can be used as a micromanipulation system. The design of FPMs with the SA characteristic consists of type synthesis of parallel mechanisms possessing the required number of degree of freedom (DOF), geometric arrangement of the structure to obtain the SA and conversion of the kinematic mechanism into the flexure mec...

Shallow lentic freshwater aquatic systems are globally important emitters of methane (CH 4 ), a highly potent greenhouse gas. Previous laboratory studies indicated that bioturbation by chironomids can reduce CH production and increase oxidation enhancing oxygen transport into sediment. Thus, reduction in chironomid density application biocides for mosquito control, such as Bacillus thuringinesi...

During the mixed-dentition stage of dental development, dentists may encounter patients with first permanent molars considered to have a poor long-term prognosis. In this situation, extraction of the tooth and space closure or use of the extraction space for future orthodontic treatment should be considered. The aim of this article is to give guidelines about treatment planning for patients who...

Background: The primary objective of this study was to assess the occurrence, distribution, and features ectopic first permanent molars (FPMs), as well investigate clinical outcomes associated with eruption based on degree root resorption observed in second molars. Methods: This performed retrospectively by examining panoramic radiographs 7070 patients aged 5 12 years. gender age patients, numb...

BACKGROUND AND AIM: First permanent molar teeth (FPMT) erupt slowly and without any side effects among the 6-8 year old children. Sweet snacks consumption, parents’ unawareness about existence of these teeth and lack of attention to oral health care cause early caries among children in these ages. First permanent molars (FPMs) have a very important role in oral cavity among children. Therefore,...

Driven by technologies and demands, the modern transportation system has developed from intelligent systems (ITS) to autonomous (ATS) resolve intertwined demands supplies with few human interventions. In ATS, personal mobility service (PMS) is that can sense real-time traffic conditions comprehensively, learn travelers’ preferences accurately, recommend multimodal travel options appropriately, ...
