How do constituent quarks arise in QCD? Perturbation theory and the infra-red
, 1996 We motivate the use of dressed charges by arguing that such objects are needed to describe, e.g., constituent quarks and, in general, physical charged states in gauge theories. We give a short introduction to dressings in both QED and QCD. We put special

A late-accelerating universe with no dark energy - and a finite-temperature big bang [PDF]
, 2005 Brane-world models offer the possibility of explaining the late acceleration of the universe via infra-red modifications to General Relativity, rather than a dark energy field.

Advanced Healthcare Materials, EarlyView.Dissolvable microneedle (MN) device containing Bacillus paralicheniformis. The polymeric matrix encapsulates and protects the bacteria, preserving their viability while enabling in situ production and release of γ‐polyglutamic acid. The bacteria are delivered into the skin via 500 µm‐long microneedles, and remain detectable on the skin 24 h post ...

A Synovium‐on‐Chip Platform to Study Multicellular Interactions in Arthritis
Advanced Healthcare Materials, EarlyView.The Synovium‐on‐Chip comprises a thin microporous PDMS membrane to support co‐culture of fibroblast‐like synoviocytes (FLS), THP‐1‐derived macrophages, and endothelial cells, enabling real‐time analysis of synovial‐vascular interactions. FLS migration through the pores drives endothelial remodeling, while TNF‐α stimulation induces robust inflammatory ...

Determination of QW laser diode degradation based on the emission spectrum
EPJ Web of Conferences, 2017 The possibility of laser diodes degradation control by monitoring of their spectrum is shown. For red and infra-red laser diodes, the time dependence of the radiation spectrum width was obtained.
