A dual-band base station antenna is introduced in this paper. The proposed composed of baluns, bowtie patches, and a split ring. two pairs patches excited by the orthogonal balun structures can achieve dual polarization. ring used to yield additional resonances broaden impedance bandwidth. In way, compact obtained with size 0.41 λc × 0.13 (λc wavelength free space at lowest operating frequency ...

Asia is a heterogeneous region with substantial variability in economic, social and palliative care development. While the global consumption of opioids has increased, the consumption in most Asian countries has not increased at the same rate. This is the first comprehensive study of opioid availability and accessibility for cancer patients in Asia. Data are reported on the availability and acc...

A total of 13 short DNA sequences of quality control strains (MCC 2052, MCC 2077, MCC 2078, MCC 2080, MCC 2309, MCC 2322, MCC 2408, MCC 2409, MCC 2412, MCC 2413, MCC 2415, MCC 2483 and MCC 2515) were retrieved from NCBI BioSample database and generated quick response (QR) codes for sequences. 16S rRNA was used for creation of Chaose Game representation (CGR), Chaose Game Representation of Frequ...

We investigate the cosmological consequences of particle physics theories that admit stable loops of superconducting cosmic string vortons. General symmetry breaking schemes are considered, in which strings are formed at one energy scale and subsequently become superconducting in a secondary phase transition at what may be a considerably lower energy scale. We estimate the abundances of the ens...

Context-oriented programming (COP) is a new technique for programming that allows changing the context in which commands execute as a program executes. Compared to object-oriented programming (aspectoriented programming), COP is more flexible (modular and structured). This paper presents a precise syntaxdirected operational semantics for context-oriented programming with layers, as realized by ...

A total of 2515 people attending a large military hospital in Saudi Arabia was studied clinically, serologically, and (when appropriate) radiologically for evidence of treponematosis. The indications are that non-venereal endemic syphilis (bejel) is prevalent among the nomadic communities living in rural areas. In contrast, venereal syphilis is much less common, and is found almost exclusively ...

Forage accumulation yields and nutritive value of 12 Urochloa cultivars pre-commercial lines (Mulato II, Cayman, Cobra, Marandu, Toledo, BRS Piatã, Paiaguás, Ruzi, Humidicola, BRO4/3025, BRO4/3207 BRO4/2515) were evaluated in a field trial Northeast Thailand during 2015–2018. Total herbage for over 3 years ranged from 15,800 kg DM/ha (Ruzi) to 33,800 (Toledo). Toledo produced the highest total ...
