Visual computation of surface lightness: Local contrast vs. frames of reference [PDF]

, 2010
Seeing black, white and gray surfaces, called lightness perception, might seem simple because white surfaces reflect 90% of the light they receive while black surfaces reflect only 3%, and the human retina is composed of light sensitive cells.

Effect of Fabric Properties on Optical Parameters of Pigment-Based Inkjet Prints

Технологія і техніка друкарства
The article presents the results of an experimental study on the influence of the physical properties of natural fabrics on the optical characteristics of prints produced by direct inkjet printing with pigment inks. In response to the growing demand for

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Approaches to Surface-evaluation of Compressive Strength of Concrete in Structure Based on Lightness Changing on Concrete Surface by Water Sprinkling [PDF]

, 2013
This paper is reported the result of approaches to nondestructive surface-evaluation of concrete in structure by comparing with strength of core and estimated strength based on lightness changing of concrete surface by water sprinkling.

Lightness constancy and illumination discounting

, 2011
Contrary to the implication of the term “lightness constancy”, asymmetric lightness matching has never been found to be perfect unless the scene is highly articulated (i.e., contains a number of different reflectances). Also, lightness constancy has been

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

As Light as a Whale: Roberto Abbiati’s Una tazza di mare in tempesta and the Presence of Moby-Dick in Contemporary Italian Arts

Nalans
Ever since Cesare Pavese’s pioneering 1932 translation of Moby-Dick; or, The Whale, Italy has proven particularly receptive to Herman Melville’s masterpiece, which has not only been enthusiastically loved by generations of readers and stimulated the ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
