Broadband microwave signals with customized chirp shapes are highly captivating in practical applications. Compared with electronic technology, photonic solutions are superior in bandwidth but suffer from flexible and rapid manipulation of chirp shape or frequency. Here, we demonstrate a concept for generating broadband microwave signals with programmable chirp shapes.

Electroencephalographic signals are obtained by amplifying and recording the brain's spontaneous biological potential using electrodes positioned on the scalp. While proven to help find changes in brain activity with a high temporal resolution, such signals are contaminated by non-stationary and frequent artefacts. A plethora of noise reduction techniques have been developed, achieving remarkable performance.

Background: In the context of injectable biologic products approved or in development for chronic spontaneous urticaria (CSU), it is important to capture which treatment attributes matter most to patient and what trade-offs patients are willing to make.
Objectives: The CHOICE-CSU study aimed to quantify patient preferences toward injectable treatment attributes among patients with CSU, inadequately controlled by H1-antihistamines.
Methods: This was a two-phase cross-sectional patient preference study in adult patients with a diagnosis of CSU, inadequately controlled by H1-antihistamines.

ConspectusSymmetry is a pervasive phenomenon spanning diverse fields, from art and architecture to mathematics and science. In the scientific realms, symmetry reveals fundamental laws, while symmetry breaking─the collapse of certain symmetry─is the underlying cause of phenomena. Research on symmetry and symmetry breaking consistently provides valuable insights across disciplines, from parity violation in physics to the origin of homochirality in biology.

A squaramide-based monomer, designed for topochemical azide-alkyne cycloaddition (TAAC) polymerization, crystallizes as two polymorphs, M1 and M2, both having crystal packing suitable for topochemical polymerization. The hydrogen-bonding between squaramide units bias the molecular organization in both the polymorphs. 3D packing of H-bonded stacks of monomer lead to juxtaposition of azide and alkyne units of adjacent molecules in a transition-state-like arrangement for their regiospecific cycloaddition reaction.
