title: Spanish Sign Language Alphabet

description: Description:







The Spanish Sign Language Alphabet dataset consists of 19 static letters and 8 dynamic movements. It was created with the aim of supporting machine learning models for sign language recognition, particularly the Spanish sign language alphabet.

Dataset Composition

The dataset contains around 100 images for each of the 19 static letters. Each image was captured over a white background with high-quality cameras. These images represent three different hands at a uniform distance, simulating the perspective from an internal smartphone camera.

 







Download Dataset

 









Expert Validation

To ensure high accuracy, the dataset was reviewed and validated by a certified expert in Spanish sign language. This guarantees that each letter is correctly represented, making the dataset a valuable resource for machine learning applications.

Applications

This dataset is ideal for training models in:



Gesture and static sign language recognition

Computer vision projects focused on human-computer interaction

Accessibility technology development for the hearing-impaired community


Benefits of the Dataset



High-quality, standardized images

Multiple hand perspectives ensure model robustness

Realistic simulation of smartphone camera view for practical applications

Suitable for researchers focusing on AI, sign language translation, and accessibility solutions


Potential Use Cases



AI and Machine Learning: Can be used to train AI models for recognizing static signs.

Computer Vision: Enhances projects in gesture recognition and human-computer interaction.

Accessibility Technology: Advances sign language translation for hearing-impaired users.

title: Replication Data for: Interplay between light and heavy electron bands in magic-angle twisted bilayer graphene

description: &lt;b&gt;Device fabrication&lt;/b&gt;&lt;br&gt;
The MATBG devices were fabricated using a cut-and-stack technique. All flakes were first exfoliated on a Si/SiO2 (285 nm) substrate and later picked up using a polycarbonate (PC)/polydimethylsiloxane (PDMS) stamp. All of the layers were picked up at a temperature of T ≈ 100 °C. We used an atomic force microscope tip to cut the graphene to avoid strain during the pick-up process. The PC/PDMS stamp first picked up the top graphite layer, the top hBN and the first graphene layer. Before picking up the second graphene layer, we rotated the stage by an angle of θ = 1.1°. Finally, the stamp picked up the bottom hBN and bottom graphite gates. We dropped the finalized stack onto a Si/SiO2 substrate by melting the PC at T ≈ 180 °C. The resulting stack was etched into a Hall bar using a CHF3/O2 plasma and one-dimensional contacts were formed by evaporating Cr (5 nm)/Au (50 nm) (Supplementary Fig. 1b). We etched a narrow channel of width d ≈ 150 nm in the top gate using an O2 plasma. Before etching the top gate, the device was characterized in transport using a four-probe configuration at TL = 35 mK to identify the pair of contacts closest to the magic angle of θ = 1.1°. The junction was made between this pair of contacts.&lt;br&gt;&lt;br&gt;

&lt;b&gt;Transport measurements&lt;/b&gt;&lt;br&gt;
Transport studies for the characterization of the two samples were carried out in a dilution refrigerator (BlueFors SD250) with a base temperature of 20 mK and a VTI cryostat (ICEOxford) with a base temperature of 1.55 K. Further transport measurements were performed in situ in the optical cryostat (Attodry 800, base temperature 6 K) used for the optoelectronic measurements. All transport measurements were performed using a standard low-frequency lock-in technique (Stanford Research SR860 amplifiers) with frequency f = 17.177 Hz.&lt;br&gt;&lt;br&gt;

&lt;b&gt;Optoelectronic measurements&lt;/b&gt;&lt;br&gt;
We studied the optoelectronic response of the MATBG p–n junctions using standard d.c. and low-frequency a.c. transport measurements combined with scanning laser microscopy. All optoelectronic measurements were performed in an Attodry 800 cryostat with free-space optical access.
