The subject of this paper concerns the design and optimization a helical open waveguide structure for thermal tumor ablation with microwaves, treatment also known as MicroWave Ablation (MWA). A variety antennas MWA have been developed so far. However, most these cannot accurately control temperature field they produce. As result, heating extends to healthy tissues well. Therefore, first innovation proposed here is use that will distribution deposited electromagnetic power achieve total...
Matrix metalloproteinases (MMPs) are proteolytic enzymes important at several points during multistep neoplastic progression. Although MMP-1 and MMP-3 have been implicated in the progression of various human cancers, their expression bladder cancer has not addressed. Immunohistochemistry (Strept-ABC-HRP method) situ hybridization were performed to detect protein, mRNA, respectively, 59 transitional cell carcinomas. To assess role these MMPs cancer, was evaluated relation known...
The goal of the study presented in this paper is to investigate performance MIMO-WCDMA networks, where Principal Component Analysis (PCA) employed at reception. In context, multipath propagation exploited, as individual received signals can be seen different instances same physical phenomenon (i.e. transmission and reception WCDMA sequences). As results indicate, deployment PCA technique networks significantly reduce number active channels that need fed back transmitter. particular, for...
Although foreign bodies left in the abdominal cavity may remain asymptomatic for long periods, they also cause serious complications. We present a case of gauze forgotten lower abdomen which remained almost 1 year. When granuloma had formed, it infiltrated bladder wall giving clinical and imaging appearance an invasive tumor.
The work at hand explores the chipless RFID coding enhancement via employment of characteristic mode theory. presented results are comparable in performance with some state art ones giving confidence that much better density can be achieved.
The cylindrical wave - planar interface electromagnetic interaction is studied in the current work. To best of our knowledge, modeling this either computationally intensive, time consuming or reduced accuracy especially when source electrically close to interface. Here we propose a method that alleviates both those problems. based on analytical computation Sommerfeld integral representation Hankel function after expressing plane reflection coefficient complex exponential series form.
An alternative variational modal analysis technique is contributed by this study. Although the weak form of Maxwell equations employed, instead using finite elements technique, authors utilise entire/global domain vectorial basis functions. In such a case, to assist performance, functions must comply with boundary conditions. Since in general, difficult task, they adopt following strategy. They transform initial convex cavity coordinate transformation canonical one, where known complete set...
In this work, a frequency pulling technique (FPT), inspired by the band-pass filter synthesis, is proposed for increasing bandwidth of symmetric-shaped antennas. Namely, simultaneously feeding triangular patch antenna three symmetric points, we are able to triple its compared traditional single-fed counterpart. To feed our patch, three-way power divider that applies consecutive phase difference 90° at each input port printed under aperture as FPT requires. With design methodology not only...
