Snow‐Covered Insights From Above and Below: High‐Frequency Measurement of Nitrogen Dioxide From Space and Ground

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite provides hourly air quality measurements over North America. This study evaluates TEMPO NO2 ${\text{NO}}_{2}$ observations over snow‐covered surfaces, highlighting its ability to capture sharp spatial and temporal gradients in NO2 ${\text{NO}}_{2}$ vertical column densities ...

Analysis of satellite-derived Arctic tropospheric BrO columns in conjunction with aircraft measurements during ARCTAS and ARCPAC [PDF]

, 2012
We derive tropospheric column BrO during the ARCTAS and ARCPAC field campaigns in spring 2008 using retrievals of total column BrO from the satellite UV nadir sensors OMI and GOME-2 using a radiative transfer model and stratospheric column BrO from a ...

Dynamic option adjusted spread and the value of mortgage backed securities [PDF]

, 2007
We extend a reduced form model for pricing mortgage-backed securities (MBS) pass through and provide a novel hedging tool for investors in this market. To calculate the price of an MBS traders use what is known as option-adjusted spread (OAS).

Targeting the CMKLR1‐Mediated Signaling Rebalances Immunometabolism State in Middle‐Age Testicular Macrophages

Advanced Science, Volume 13, Issue 14, 9 March 2026.
In middle age, testicular CMKLR1⁺ macrophages exhibited a pro‐inflammatory immunometabolic profile, mediated by adipose signals associated with high BMI. However, inhibition of CMKLR1 signaling, either through Cmklr1 genetic ablation or treatment with a CMKLR1 antagonist peptide, can reverse this phenotype.

Investigating Drivers of Tiger Bone Glue Consumption in Vietnam 调查越南虎骨胶消费的驱动因素 Điều Tra Nguyên Nhân Dẫn Đến Tình Trạng Tiêu Thụ Cao Hổ Cốt Tại Việt Nam

Integrative Conservation, Volume 5, Issue 1, Page 115-124, March 2026.
We found the estimated use of tiger bone glue within the last 12 months to be 6.9%. We found a stated motivation of taking TBG to improve health, and by the suggestion of one's social group. We suggest reducing the acceptability of TBG as medicine and encouraging non‐animal‐based medicinal alternatives.

Impact of a substance use screening program on racial disparities in urine toxicology testing

Pregnancy, Volume 2, Issue 2, March 2026.
Abstract Objective To evaluate whether implementing a standardized substance use screening program reduced racial disparities in urine toxicology (Utox) testing among delivery admissions. Methods We conducted a retrospective cohort study of delivery admissions at a single academic center from June 2019 to June 2025. To address known disparities in Utox

Domain-of-Attraction Estimation for Uncertain Non-polynomial Systems

, 2013
In this paper, we consider the problem of computing estimates of the domain-of-attraction for non-polynomial systems. A polynomial approximation technique, based on multivariate polynomial interpolation and error analysis for remaining functions, is ...

Kepemimpinan Cendekia: SYIAR, DOA, & IKHTIAR

, 2021
Buku ini menegaskan bahwa kepemimpinan itu soal karakter yang termanifestasi dalam sikap dan perbuatan. Dalam bahasa agama disebut akhlak. Hal ini sejalan dengan ungkapan: Leadership is not a position or a title but is an action and example. Kepemimpinan tidak terkait langsung dengan posisi, jabatan, dan kedudukan seseorang, tetapi terkait dengan sikap
