The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and the National School Lunch Program (NSLP) are designed to increase food security and reduce hunger for children from low-income households. Since the cutoff age for WIC is five, and school enrollment is required for receiving free or reduced-price NSLP, some children from low-income households cannot receive both WIC and free or reduced-price NSLP. Using data from the Current Population Survey, the partial identification method developed in this paper addresses the problems of self-selection into WIC and systematic underreporting of program participation.

Job losses spiked in April 2020, and partially recovered in subsequent months. Non-metropolitan and metropolitan areas of all sizes experienced significant employment losses, but the impacts were much larger in large metropolitan areas.

Molecularly imprinted polymer (MIP) powders were prepared using a simple complexation strategy between the polymer carboxylate groups and template molecule followed by metal cation cross-linking of residual polymer carboxylates. Polymer powders were formed in situ by templating carboxylic acid containing polymers with 4-ethylaniline (4-EA), followed by addition of an aqueous CaCl2 solution. The solution remained homogeneous.

Although the adrenal gland is a common site of metastasis from hepatocellular carcinoma (HCC), adrenal metastases are rarely seen in clinical practice because of its lower metastatic potential compared to the other malignancies. Adrenal metastases usually were detected at the time of diagnosis of primary HCC or simultaneously with intrahepatic recurrence after curative management of HCC. It is very rare that only metastatic HCC is detected without evidence of intrahepatic recurrence.
