Double‐bowtie filter design for pediatric spectral CT imaging: A fan beam simulation study

Medical Physics, Volume 53, Issue 11, November 2026.
Abstract Background Despite concerns about radiation dose in pediatric patients, computed tomography (CT) remains a first‐line imaging modality for children. Spectral CT provides additional diagnostic information that benefits pediatric imaging. However, most existing spectral CT systems are primarily optimized for adult patients.

A Low Power and Flat Gain CMOS RFPA For UWB Applications Using Complementary Current Reuse Stage [PDF]

SVU-International Journal of Engineering Sciences and Applications
A low power, high linearity, and flat gain ultra-wideband radio frequency power amplifier (UWB RFPA) circuit design for 3.1-10.6 GHz is proposed in 0.18 um CMOS process. To achieve linear and flat gain over the whole frequency band, the UWB RFPA is built

Site‐specific O‐glycans influence lacritin structure and multimerization in tears

Protein Science, Volume 35, Issue 11, November 2026.
Abstract Lacritin is an abundantly expressed glycoprotein in tear fluid and plays key roles in immune response, tear secretion, and bacterial killing. These biological functions are tightly regulated through several biochemical mechanisms including multimerization, proteolysis, and alternative splicing, especially within its C‐terminal domain.

High Performance and Highly Robust AlN/GaN HEMTs for Millimeter-Wave Operation

IEEE Journal of the Electron Devices Society, 2019
We report on a 3 nm AlN/GaN HEMT technology for millimeter-wave applications. Electrical characteristics for a 110 nm gate length show a maximum drain current density of 1.2 A/mm, an excellent electron confinement with a low leakage current below 10 ...

Lost in translation? Injunctions and patent enforcement in a transatlantic perspective

The Journal of World Intellectual Property, Volume 29, Issue 3, Page 479-502, November 2026.
Abstract As the European Directive on the Enforcement of Intellectual Property Rights (IPRED) marked the twentieth anniversary of its adoption, renewed calls have emerged for its revision, aimed at fostering a more effective application of the principle of proportionality in patent enforcement.

Pursuing patents for their own sake: How the investment discourse shapes patent quality and quantity

The Journal of World Intellectual Property, Volume 29, Issue 3, Page 626-650, November 2026.
Abstract Patent systems worldwide face criticisms over declining patent quality and increasing patent quantity. While most research focuses on strengthening examination rigour, this article turns attention to relatively underexplored patenting incentives.

Assessing Zymoseptoria tritici Candidate Effectors in the Non‐Host Nicotiana benthamiana Reveals Immune Recognition and Potential Host‐Independent Activities

Molecular Plant Pathology, Volume 27, Issue 11, November 2026.
To investigate effector functions in Zymoseptoria tritici, we transiently expressed seven candidate effectors in the non‐host Nicotiana benthamiana. Responses reflected a combination of immune recognition and potential conserved activities, and primarily serve to prioritize candidates for validation in the native wheat–Z. tritici interaction.

Apportioning Sources of Nitrogen Oxides in California's San Joaquin Valley Using Observations From Three Airborne Field Campaigns

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Emissions of nitrogen oxides (NOx = NO + NO2), a precursor to ozone and secondary aerosol formation have become increasingly important to understand as ozone production transitions to NOx limited in most regions of the US. Recent studies suggest that NOx emissions associated with agricultural activities, particularly cropland soils, are an ...
