Bernoulli Wavelets Method for Solution of Fractional Differential Equations in a Large Interval

open access: yesپژوهش‌های ریاضی, 2016
In this paper, Bernoulli wavelets are presented for solving (approximately) fractional differential equations in a large interval. Bernoulli wavelets operational matrix of fractional order integration is derived and utilized to reduce the fractional ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

On Absolute Nörlund Spaces and Matrix Operators

open access: yesActa Mathematica Sinica, English Series, 2017
An absolute Nörlund space \(|N_p^{\theta}|_k\) is introduced as an extension of absolute Cesàro space \(|C_\alpha|_k\). For \(k\geq 1\) the space \(|N_p^{\theta}|_k\) is defined as: \[ |N_p^{\theta}|_k = \Big\{a=(a_\upsilon): \displaystyle\sum_{n=1}^{\infty}\theta_n^{k-1}\Big|\sum_{\upsilon=1}^{n}\Big(\frac{P_{n-\upsilon}}{P_n}-\frac{P_{n-1-\upsilon ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Sinc-Fractional Operator on Shannon Wavelet Space

open access: yesFrontiers in Physics, 2018
In this paper the sinc-fractional derivative is extended to the Hilbert space based on Shannon wavelets. Some new fractional operators based on wavelets are defined.

Matrix Meta-Operational Mathematics: From Iteration of Matrix Operations to Matrix Meta-Operations

open access: yes
This paper develops Matrix Meta-Operational Mathematics, a systematic and exhaustive framework that elevates matrix-valued operations themselves to the status of independent mathematical objects, thereby extending the scalar meta-operational framework to the non-commutative matrix algebraic setting with full mathematical rigor and unprecedented detail.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
