A Framework for Ultralow Surface-brightness Integral-field-unit Emission Mapping with the Keck Cosmic Web Imager
Published August 2026 | Version Published Journal Article Open Detecting spatially resolved emission at surface-brightness levels of ∼10−20–10−19 erg cm−2 s−1 arcsec−2 Å−1 in optical integral-field spectroscopy requires reduction procedures limited not by photon statistics, but by systematic effects such as sky subtraction, cosmic-ray (CR) contamination, correlated noise, and detection methodology.
Kinematically Complex Circumgalactic Gas Around a Low-mass Galaxy: Filamentary Inflow and Counterrotation in J0910b
Published December 10, 2025 | Version Published Journal Article Open We present the first detailed, spatially resolved study of the circumgalactic medium (CGM) surrounding the low-mass, low-redshift star-forming galaxy J0910b (SDSS J091458.61+110845.1; M⋆ ∼ 109.2 M⊙, z = 0.096), focusing on its gas dynamics, ionization mechanisms, and kinematics. J0910b is the lowest-mass galaxy in our low-redshift CGM survey using the Keck Cosmic Web Imager (KCWI).
Mitogenomic phylogeny and divergence time estimation of Artemia Leach, 1819 (Branchiopoda: Anostraca) with emphasis on parthenogenetic lineages - BMC Genomics
The mitogenomes of the nine species and four parthenogenetic lineages represent typical circular DNA, including 22 tRNAs, 2 rRNAs, 13 PCGs and a noncoding control region exhibiting a total length ranging from 15,433 bp (SAL1, GenBank accession no.: OR423222) to 15,829 bp (FRA1, GenBank accession no.: OR423224), respectively.

The Evolution and Impact of Distilled Spirits Regulation in the United States: Considerations for Policymakers and Academia
1. Introduction The alcohol industry composed broadly of beer, wine, and distilled spirits is highly regulated in the United States, none more so than distilled spirits. The prohibition hangover continues to impact the United States distilled spirits industry, evident in many state and federal regulations that impede the ability to produce and purchase distilled spirits.
Cash Rules Everything around Me: Investigating Craft Beer Drinkers Purchase Decisions during Inflationary Period
1. Introduction Wu-Tang might have been referring to the struggle of making enough money to deal with life’s many expenses; however, nearly 30 years later many Americans found themselves struggling to pay for nearly everything as inflation skyrocketed. As of August 2022, it was expected that household expenditures—this includes housing, food, entertainment, clothing, transportation, etc.—would average USD 72,900 or roughly USD 11,500 more than in 2020 [1].

High-grade portal vein thrombosis (PVT) is often considered to be a relative contraindication for liver transplantation (LT). This study compares patients with chronic, obliterative PVT, who underwent portal vein recanalization-transjugular intrahepatic portosystemic shunt (PVR-TIPS) and subsequent LT, to those with partial, non-occlusive PVT who underwent LT without an intervention.
Management: Seven Signs Your Workplace is Toxic

Service Before Product: A New Approach
Service Before Product: A New Approach D. Alan Christopher, MAS - August 1, 2017 Three Ways To Move The Industry From Goods-Dominant To Service-Dominant Have you ever wondered where marketing came from, or where it’s going? To understand something we must always understand first where it came from. Then we might have a better chance at predicting where it is going. Marketing evolved from the early work in economics.

Everolimus-Eluting Bioresorbable Scaffolds for Coronary Artery Disease
The Absorb bioresorbable vascular scaffold (Abbott Vascular) consists of a 150-μm-thick bioresorbable poly(l-lactide) scaffold with a 7-μm-thick bioresorbable poly(d,l-lactide) coating, which elutes everolimus. This bioresorbable vascular scaffold has been studied in registries 13-15 and in three modest-sized randomized trials.
