Production and characterization of homologous protoporphyrinogen IX oxidase (PPO) proteins: Evidence that small N-terminal amino acid changes do not impact protein function.

PLoS ONE
Transgenic soybean, cotton, and maize tolerant to protoporphyrinogen IX oxidase (PPO)-inhibiting herbicides have been developed by introduction of a bacterial-derived PPO targeted into the chloroplast.

KLip-PPO: A per-sample KL perspective on PPO-Clip

Proximal Policy Optimization (PPO) is the standard policy-gradient algorithm for on-policy reinforcement learning. The literature presents it in two forms, a clipped surrogate that bounds the importance ratio between successive policies and a Kullback-Leibler penalty between them. These forms are treated as separate algorithms with their own gradients,

Distributional Effect of Insurer Competition on Premiums: Evidence From the Employer‐Sponsored Health Insurance Market

The RAND Journal of Economics, EarlyView.
ABSTRACT We study how insurer competition affects premiums for fully‐insured plans in the employer‐sponsored health insurance market. By utilizing quasi‐experimental variations induced by mergers among national insurers, we show that increased insurer concentration leads to higher premiums, but there exists substantial heterogeneity.

Prospective subtyping of head and neck basal cell carcinoma by dermoscopy and handheld RCM

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Handheld reflectance confocal microscopy, alone or with dermoscopy, increases specificity, maintains high sensitivity and improves diagnostic confidence for head and neck basal cell carcinoma. It may offer a non‐invasive alternative to confirmatory biopsies when planning micrographically controlled surgery in clinically high‐risk cases.
