  1. 1. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

    Author : Aravin Chakravarthi; Funktionell zoologi; []
    Keywords : Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

    Abstract : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. READ MORE

  2. 2. Exploring Biological Systems using Spatial Transcriptomic Technologies

    Author : Kim Thrane; Joakim Lundeberg; Patrik Ståhl; Ulf Gyllensten; KTH; []
    Keywords : Spatial Transcriptomics; single-cell RNA-seq; scRNA-seq; spatial VDJ; Spatial Isoform Transcriptomics; Biotechnology; Bioteknologi;

    Abstract : The transcriptome and the cells’ spatial organization are important determinants for the functions of biological systems, such as a tumor, brain, or skin tissue. Single-cell RNA sequencing (scRNA-seq) has emerged as a powerful tool for profiling the transcriptome of individual cells. READ MORE

  3. 3. Spatial vision in diverse invertebrates

    Author : John Kirwan; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; vision; visual ecology; invertebrates; spatial resolution; behaviour;

    Abstract : Light-detection provides incomparabaly rapid information at a range of time scales and, consequently, directional photoreception is found in almost every major metazoan clade. Conversely, a much smaller cohort have evolved sophisticated high resolution vision, which facillitates complex tasks via the detection of fast or small objects,. READ MORE

  4. 4. Spatial Vision in Birds: Anatomical investigation of spatial resolving power

    Author : Mindaugas Mitkus; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Raptors; Seabirds; Parrots; Birds; Double cones; Development; Retinal ganglion cells; Visual spatial resolution; Visual ecology; Vision;

    Abstract : Avian eyes are big both in relative and absolute terms, thus the importance of vision to birds is obvious. Even though the general eye plan is rather conservative throughout the group, there is a great variation in visual capabilities. READ MORE

  5. 5. The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography

    Author : Mark Ruschin; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D breast imaging; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; hybrid images; dose reduction; spatial resolution; pixel size; Breast cancer; digital mammography; radiologi; tomografi; medicinsk instrumentering; breast tomosynthesis;

    Abstract : Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. READ MORE
