Recently, a single vectorial pupil optimization (VPO) was proposed to compensate for the polarization effect induced by thick mask and image optics at one field point in a lithography system, which does not work at full field points. In this paper, we propose a multi-objective VPO (MOVPO) method to obtain a universal vectorial pupil that can compensate for the polarization aberration at full field points. A novel multi-objective cost function, to the best of our knowledge, is built and includes uneven image pattern errors causing by polarization aberration (PA) at full field points in the MOVPO method. Comprehensive simulations demonstrate that the proposed MOVPO method can effectively improve the consistency of imaging and enlarge the overlapped process window at full field points.

Plast Reconstr Surg Glob Open
January 2025
Department of Plastic and Reconstructive Surgery, Royal Free NHS Foundation Trust, London, United Kingdom.
Background: There has been a delayed, yet steady uptake of robotic-assisted surgery over the past decade within the field of plastic surgery. In an era of rapidly evolving scientific and technological development, there is a need for an update on the current literature for robotic-assisted plastic surgery procedures.
Methods: Searches were conducted across major databases, including MEDLINE, Embase, and Central for published literature from March 2023 to December 2024.
Development of a vegetation canopy reflectance sensor and its diurnal applicability under clear sky conditions.

The spectral reflectance provides valuable information regarding vegetation growth and plays an important role in agriculture, forestry, and grassland management. In this study, a small, portable vegetation canopy reflectance (VCR) sensor that can operate throughout the day was developed. The sensor includes two optical bands at 710 nm and 870 nm, with the light separated by filters, and has a field of view of 28°.

Background: Ovarian cancer is a leading cause of mortality worldwide. The third most prevalent gynecological cancer globally, following cervical and uterine cancer, and the third leading cause of cancer-related mortality among women in Sub-Saharan Africa, including Ethiopia. The time ovarian cancer patients have to wait between diagnosis and initiation of treatment are the indicators of quality in cancer care and influence patient outcomes.

The accuracy of metacognitive judgments is rarely incentivized in experiments; hence, it depends on the participants' willingness to invest cognitive resources and respond truthfully. According to arguments promoted in economic research that performance cannot reach its full potential without proper motivation, metacognitive abilities might therefore have been underestimated. In two experiments (N = 128 and N = 129), we explored the impact of incentives on the accuracy of judgments of learning (JOLs), memory performance, and cue use in free recall of word lists.

Faculty of Chemical Engineering, Tarbiat Modares University, Tehran, Iran.
Gas foam injection offers a viable solution to challenges faced in oil reservoirs, yet ensuring optimal foamability and stability remains a pivotal hurdle in practical field operations. This study presents a novel synthesis procedure to create silica (SiO) Janus nanoparticles (JNPs) and examines their potential to enhance gas foam stability for enhanced oil recovery (EOR) applications. Two variations of SiO JNPs were synthesized via a masking procedure, employing oleic acid and ascorbic acid within a Pickering emulsion, marking a pioneering approach.
