'Cristian Fàbrega' 'Andreas Waag' 'Joan Daniel Prades'] Color QR Codes are often generated to encode digital information, but one also could use colors or to allocate colors in a QR Code to act as a color calibration chart. In this dataset, we present several thousand QR Codes images generated with two different…

'Pei Lv' 'Bing Zhou'] Abstract—QR codes are usually scanned in different environments, so they must be robust to variations in illumination, scale, coverage, and camera angles. Aesthetic QR codes improve the visual quality, but subtle changes in their appearance may cause scanning failure. In this paper, a new method…

'José Luis Vázquez-Poletti' 'Nikolaos Schetakis' 'Konstantinos Stavrakakis' 'Alessio Di Iorio' 'María Estefanía Avilés Mariño'] This paper introduces a novel approach for encoding information in PDF documents or similar files. The proposed encoding involves a dual-step method: firstly, the information is encoded in…

'Wing Cheong Lau'] Abstract—The use of color in QR codes brings extra data capacity, but also inflicts tremendous challenges on the decoding process due to chromatic distortion—cross-channel color interference and illumination variation. Particularly, we further discover a new type of chromatic distortion in…

Free chlorine (FC) plays a crucial role in ensuring the safety of drinking water by effectively inactivating pathogenic microorganisms. However, traditional methods for measuring FC levels often require specialized equipment and laboratory settings, limiting their accessibility and practicality for on-site or…

'Yu-Hsin Hung'] A novel dual-message QR code is proposed for carrying two individual messages that can be read by standard QR code readers: one from a close range and the other from a large distance. By exploring the module value determining the rule of typical QR code readers, we designed two-state module blocks that…

With the ubiquity of smartphones, the Quick Response (QR) code has become one of the most-used types of two-dimensional codes, and has been popularly applied in many scenarios including social networks, mobile payments, and advertisements. Traditional QR codes are matrix codes consisting of black-and-white squares…

'Pei Lv' 'Bing Zhou'] Abstract—With the continued proliferation of smart mobile devices, Quick Response (QR) code has become one of the most-used types of two-dimensional code in the world. Aiming at beautifying the visual-unpleasant appearance of QR codes, existing works have developed a series of techniques. However…

Photoswitches exhibiting large structural variation, visible light responsiveness, and multifunctionality are important for both chemistry and bionics research. However, beyond the limited variety of functional motifs, removing high-energy UV light in photoactivatable systems remains a challenge. Herein, we report a…

—Embedding a programming language in a QR code is a new and extremely promising opportunity, as it makes devices and objects smarter without necessarily requiring an Internet connection. In this paper, all the steps needed to translate a program written in a high-level programming language to its binary representation…

Small fish species, like zebrafish or medaka, are constantly gaining popularity in basic research and disease modeling as a useful alternative to rodent model organisms. However, the tracking options for fish within a facility are rather limited. Here, we present an aquatic species tracking database, Zebrabase…

With the growing number of multicampus interdisciplinary projects in academic institutions, there is an increasing need for tracking systems that make device and sample data and associated results instantly accessible to all collaborators involved. This need has become particularly salient with the COVID pandemic and…

Management of research-animal colonies is vital for lab productivity in preclinical research. Labs often rely on inefficient paper-based or spreadsheet-based methods to manage animal colonies. Dedicated software-based solutions are generally expensive and many lack remote access. Currently available open-source…

'Chandrasekhar Narayanaswami'] Quick response codes – 2D patterns that can be scanned to access online resources – are being used in a variety of industrial and consumer applications. However, it is problematic to use multiple QR codes in close proximity: scans can fail or result in access to the wrong resource. While…

Multimedia approaches, including short instructional videos, are complementary to traditional modes of instruction such as in-person lecture and written procedures. We describe the creation and implementation of Quick Reference (QR) instructional videos in an undergraduate organic chemistry laboratory (OCL) setting for…

Despite the promise of self-driving laboratories to accelerate discovery, their widespread implementation is hindered by prohibitive cost and technical complexity. We introduce BrickSDLab, a fully functional self-driving lab platform built entirely from LEGO® components, designed to bridge this accessibility gap.…
