This document contains several optical illusions designed to trick the eye and brain. It includes images that appear to change or morph depending on how they are viewed, such as black spots that seem to move or figures that alternate between a rabbit and duck. The document also features visual puzzles and hidden images to find, such as discerning the number inside a colored circle or finding a hidden dog in a snow scene. The purpose is to demonstrate how perception can be influenced through optical tricks that create unexpected visual effects or ambiguous figures open to more than one interpretation.

This document contains several optical illusions including images that appear to move when viewed from different angles, ambiguous images that can be interpreted in multiple ways, impossible objects, and images designed to trick the eye. The illusions demonstrate how visual perception can be influenced or deceived by the way an image is presented on a 2D surface.Optical illusions

The document discusses optical illusions and mental agility exercises presented through various illusion images. It includes images that play tricks on perception by appearing to change or contain hidden images when viewed in different ways. The director of the Dionysus camp introduces topics like whether shapes or letters are darker, apparent motion effects, hidden images, and images that can be interpreted in multiple ways like a vase or faces. The purpose is to challenge perception and thinking through visual puzzles and illusion.Test Your Observation

This document consists of a series of visual illusions and ambiguous images accompanied by questions intended to challenge the reader's perception. Some examples include questions about the number of dots, lines, or shapes in an image; whether images appear to move or change as the viewer observes them; and determining whether images represent different objects or scenes depending on one's perspective. Many of the images are designed to appear impossible or paradoxical in some way.Optical illusions for my esl class

Iron oxide-hydroxide minerals in Martian dust provide crucial insights into
Mars’ past climate and habitability. Previous studies attributed Mars’ red color
to anhydrous hematite formed through recent weathering. Here, we show that
poorly crystalline ferrihydrite (Fe5O8H · nH2O) is the dominant iron oxidebearing phase in Martian dust, based on combined analyses of orbital, in-situ,
and laboratory visible near-infrared spectra. Spectroscopic analyses indicate
that a hyperfine mixture of ferrihydrite, basalt and sulfate best matches Martian dust observations. Through laboratory experiments and kinetic calculations, we demonstrate that ferrihydrite remains stable under present-day
Martian conditions, preserving its poorly crystalline structure. The persistence
of ferrihydrite suggests it formed during a cold, wet period on early Mars
under oxidative conditions, followed by a transition to the current hyper-arid
environment. This finding challenges previous models of continuous dry oxidation and indicates that ancient Mars experienced aqueous alteration before
transitioning to its current desert state.

We investigate how localization precision and the depth of optical imaging affect host association and discuss the implications of such a low-luminosity dwarf galaxy. Unlike the other repeaters with low-luminosity hosts, FRB 20190208A has a modest Faraday rotation measure of a few tens of rad m−2, and EVN plus Very Large Array observations reveal no associated compact persistent radio source. We also monitored FRB20190208A for 40.4hr over 2yr as part of the Extragalactic Coherent Light from Astrophysical Transients repeating FRB monitoring campaign on the Nançay Radio Telescope and detected one burst.

How could modern LA research address data-related ethics issues in informal and situated professional learning? I will identify in this talk three relevant insights based on field studies around workplace LA interventions: Firstly, in informal and situated learning, data isn’t just about the learners. Secondly, the affordances of manual and automatic data tracking for learning are very different, with manual tracking allowing a high degree of learner control over data. Thirdly, learning is not necessarily a shared goal in workplaces. These can be translated into seeing a potential for systems endowed with sufficient natural-language-processing capability (now seemingly at our fingertips with LLMs), and socio-technical design and scenario-based data collection analysis as design and research methods.PROTEIN DEGRADATION via ubiquitous pathaway

Protein degradation via ubiquitous pathway In general science, a ubiquitous pathway refers to a biochemical or metabolic pathway that is:
1. *Widely present*: Found in many different organisms, tissues, or cells.
2. *Conserved*: Remains relatively unchanged across different species or contexts.
Examples of ubiquitous pathways include:
1. *Glycolysis*: The process of breaking down glucose for energy, found in nearly all living organisms.
2. *Citric acid cycle (Krebs cycle)*: A key metabolic pathway involved in energy production, present in many cells.
3. *Pentose phosphate pathway*: A metabolic pathway involved in energy production and antioxidant defenses, found in many organisms.
These pathways are essential for life and have been conserved across evolution, highlighting their importance for cellular function and survival.

Presented at BIOSTEC 2025 in Porto, Portugal.
About ThrombUS+: Our interdisciplinary approach centers around creating a novel wearable diagnostic device utilizing autonomous, AI-driven DVT detection. This groundbreaking device incorporates wearable ultrasound hardware, impedance plethysmography, and light reflection rheography for early clot detection. ThrombUS+ is designed for postoperative patients, those undergoing lengthy surgical procedures, cancer patients, bedridden individuals at home or in care units, and women during pregnancy and postpartum.
