Blind and visually impaired people (VIP) face many challenges in writing as they usually use traditional tools such as Slate and Stylus or expensive typewriters as Perkins Brailler, often causing accessibility and affordability issues. This article introduces a novel portable, cost-effective device that helps VIP how to write by utilizing a deep-learning model to detect a Braille cell. Using deep learning instead of electrical circuits can reduce costs and enable a mobile app to act as a virtual teacher for blind users. The app could suggest sentences for the user to write and check their work

The Braille system has been used by the visually impaired for reading and writing. Due to limited availability of the Braille text books an efficient usage of the books becomes a necessity. This paper proposes a method to convert a scanned Braille document to text which can be read out to many through the computer. The Braille documents are pre-processed to enhance the dots and reduce the noise. The Braille cells are segmented and the dots from each cell is extracted and converted in to a number sequence. These are mapped to the appropriate alphabets of the language. The Braille cell has a sta

A cost-effective and portable Braille printer with low noise is designed in this study. To reach this goal, the compressive printing concept is used and the Braille typesetting, the signal transmission interface module, the signal control module, and the Braille printing cell are designed and integrated. To increase the portability, the Braille printer is designed to use A4 size paper and each page can print at most twenty-four rows and twenty-seven Braille characters in each row. The typesetting of the printing page is designed to contain twenty-seven side-by-side Braille printing cells and e

Braille Display is a device which helps the visually impaired to read a text file in Braille format and as well receive an audio output of the text file. It gives an option to the user whether to receive output in terms of braille or audio. Braille is a tactile writing language of raised dots using which blinds and visually impaired people read and write through touch. The pattern of raised dots can be read with the fingers by blinds. The number and arrangement of these dots forms alphabets, numbers and special characters. The braille output in Braille display is observed in Braille text poppe

The availability of media to learn to read the Qur'an in Braille code for blind people is very limited.

Memorizing the exercises by heart with subsequent playing on the piano, and writing down the musical text in Braille represent the two main ways of such fixation (the third one requires mastering computer programmes).

Abstract INTRODUCTION: CD137 is a TNF receptor superfamily (TNFRSF9) costimulatory receptor expressed by T cells and NK cells. Clustering-mediated CD137 signaling enhances immune cell survival, proliferation, cytokine production and memory formation. CD40 (previously TNFRSF5) is a related superfamily member expressed primarily on B cells and antigen-presenting cells (APCs) which upon clustering is also a key modulator of T cell responses. Mesothelin (MSLN) is highly upregulated on tumor cells in ovarian and pancreatic cancer and select other solid tumour histologies. To avoid systemic toxicity

Abstract ERAS-601 is a potent, small molecule allosteric inhibitor of wildtype SHP2, a non-receptor protein tyrosine phosphatase (PTP) encoded by the PTPN11 gene. ERAS-601 inhibits wild type SHP2 biochemically with an IC50 of 4.6 nM and demonstrates selectivity across panels of 300 kinases and 12 phosphatases. SHP2 mediates upstream receptor tyrosine kinase (RTK) signaling via its phosphatase-mediated regulation of guanine nucleotide exchange factors (GEFs). ERAS-601 inhibits the SHP2 dependent cycling of KRAS from the inactive GDP-bound state to the active GTP-bound state and demonstrates ant

Abstract KRAS mutations occur in about 25% of all cancers and promote oncogenesis via constitutive activation of the RAS/MAPK pathway. Targeting KRAS mutant tumors by inhibiting individual nodes in the RAS/MAPK pathway, including SHP2, SOS1, KRAS, RAF, MEK, and ERK, has shown early clinical activity, but the rapid emergence of resistance limits the benefit of monotherapy. Resistance is often mediated by reactivation of RAS/MAPK pathway signaling, which can occur by increased activation of upstream of the RAS/MAPK pathway (e.g., EGFR activation) and/or activation of RAS/MAPK pathway nodes (e.g.

Blind and visually impaired people (VIP) face many challenges in writing as they usually use traditional tools such as Slate and Stylus or expensive typewriters as Perkins Brailler, often causing accessibility and affordability issues. This article introduces a novel portable, cost-effective device that helps VIP how to write by utilizing a deep-learning model to detect a Braille cell. Using deep learning instead of electrical circuits can reduce costs and enable a mobile app to act as a virtual teacher for blind users. The app could suggest sentences for the user to write and check their work

The current study looked for signatures of reading-specific orthographic processes in braille, separate from low-level somatosensory responses and semantic processes. Of specific interest were responses in posterior parietal cortices (PPCs), because of their role in high-level tactile perception. Congenitally blind, proficient braille readers read real words and pseudowords by touch while undergoing fMRI. We leveraged the system of contractions in En

This paper presents a feature extraction method for optical Braille recognition (OBR) system to locate, extract and convert the Braille cells in one sided Indian language Braille documents. The Braille cells are located by implementing a gridbox designed using physical properties of a Braille cell. A Braille document image is a compilation of group of six dots. The physical position of each dot and its relevance with other neighboring dots in a single cell gives various Braille characters. After the grid-box is mapped with the Braille cells in the document, the mesh characters are extracted an

Braille reading consists of three basic components: tactile sensitivity, memorization of dot placement, and positional perception or detection of the location of the dots within the braille cell. Difficulty in any of those three areas leads to trouble decoding words. The presence of a visual spatial learning disability greatly decreases a student’s ability to determine positional perception. Multi-sensory reading strategies have proven effective for sighted readers who have learning disabilities. The purpose of this study was to determine the effectiveness of multi-sensory strategies when used
