Inorganic–organic hybrid perovskites offer wide optical absorption, long charge carrier diffusion length, and high optical-to-electrical conversion, enabling more than 25% efficiency of single-junction perovskite solar cells. All-perovskite four-terminal (4T) tandem cells have gained great attention because solution-processability potentially without a need for current-matching between subcells...
Objectives: This nonlinear three-dimensional finite element analysis (FEA) study evaluated the effect of number implants, distal implant inclination, and use angled abutments on stress magnitude distribution in cortical bone (CB), abutment screw (AS), prosthetic (PS) implant-supported fixed complete dentures. Methods: Nonlinear 3D FEA models mandibular dentures were created with five, four, or ...
Materials and methods RNA from tumor and adjacent normal samples was evaluated using Sure Print G3 8x60K slides (Agilent Technologies). Sixty-five tumor (T) and four normal (N) tissues were labeled with Cy5. A pool composed by nine normal samples (without the corresponding tumor assayed) was labeled with Cy3 and used in the co-hybridization. Statistical analysis was performed using two approach...
We obtain the exact solution of a general Hubbard chain with kinetic energy t, bond-charge interaction X and on-site interaction U with the only restriction t = X. At zero temperature and half filling, the model exhibits a Mott transition at U = 4t. In the metallic phase and near half filling, superconducting states are part of the degenerate ground state and are favored for small U if the syst...
depending on the parameters x, t. We assume that the parameters are chosen in such a way that the function has unique minimum at the point u = u(x, t). This happens if t < 0 or 0 < t and |x| > 4t √ 2t. (2) Then the minimizer satisfies the equation of motion of one-dimensional ideal fluid (Riemann wave equation) ut = 6uux. (3) It solves the Cauchy problem for (3) with the initial data x = u for ...
Static Random Access Memory (SRAM) to be one of the most fundamental and vitally important memory technologies today. Because they are fast, robust, and easily manufactured in standard logic processes, they are nearly universally found on the same die with microcontrollers and microprocessors. Due to their higher speed SRAM based Cache memories and System-on-chips are commonly used. Memories ar...
Tolumonas auensis Fischer-Romero et al. 1996 is currently the only validly named species of the genus Tolumonas in the family Aeromonadaceae. The strain is of interest because of its ability to produce toluene from phenylalanine and other phenyl precursors, as well as phenol from tyrosine. This is of interest because toluene is normally considered to be a tracer of anthropogenic pollution in la...
زمینه و هدف: سندرم بوتولیسم توسط نوروتوکسین باکتری کلستریدیوم بوتولینوم ایجاد می‌شود. این نوروتوکسین دارای 7 سروتیپ از A-G می‌باشد. بهترین روش برای پیشگیری از سندرم حاصل از نوروتوکسین بوتولینوم (BoNT)، استفاده از واکسن‌های نوترکیب ساخته‌شده از ناحیه اتصالی آن (به‌علت داشتن اپی‌توپ‌های کافی برای تحریک سیستم ایمنی) می‌باشد. در این مطالعه ناحیه اتصالی نوروتوکسین بوتولینوم تیپ A (BoNT/A) بررسی گردی...
This research is concerned with microwave ablation analyses using a 2.45 GHz four-tine (4T) antenna for hepatic cancer tissue. In the study, three-dimensional finite-element models were utilized to examine the tissue temperature distributions during and after MW ablation. A preliminary study was first carried out with regard to the specific absorption rates along the 4T antenna insertion depths...
In [13] for a given vectorial Boolean function F from F2 to itself it was defined an associated Boolean function γF (a, b) in 2n variables that takes value 1 iff a 6= 0 and equation F (x) + F (x + a) = b has solutions. In this paper we introduce the notion of differentially equivalent functions as vectorial functions that have equal associated Boolean functions. It is an interesting open proble...
