Background and Objectives Along with the current aging demographics in the Netherlands, the number of older first-generation migrants is also increasing. Despite studies suggesting a higher quantity of social contacts of migrants, loneliness is more common among migrants as compared to native Dutch. We theorize that migrants experience more emotional and social loneliness due to a lower satisfaction with social relationships and lower participation in social activities, respectively, compared to their native counterparts. Research Design and Methods We use data from Statistics Netherlands (N = 7,920) with first-generation migrants aged 40 years and older and their Dutch counterparts. Contact frequency, household composition, satisfaction with social relationships, relationship quality with the partner, and social activities, are used as main predictors and separate regression models for social and emotional loneliness are analyzed. Results Compared to the native Dutch, first-generation migrants are both socially and emotionally more lonely. Migrants have a similar contact frequency as the native Dutch, but are less satisfied with their social relationships, which contributes to their higher emotional, social, and overall loneliness. Migrants engage less in social activities but this does not put them at additional risk of loneliness. Discussion and Implications Migrants experience more social and emotional loneliness and are less satisfied with their social relationships compared to their native counterparts. Interventions should focus on reducing both social and emotional loneliness among older migrants. Specific attention should be paid to fostering satisfying social interactions. Additionally, encouraging migrants to broaden their social network may reduce social loneliness.

Anaplastic large cell lymphoma with a small cell pattern is a rare T-cell lymphoma. This condition is more frequently seen in younger patients and should be considered when patients present with leucocytosis and constitutional symptoms. In this report, we describe our diagnostic work-up for one such case using blood, lymph node, and bone marrow aspirate samples, highlighting the variability of antigen expression seen in different sample types and methodologies. This case shows the importance of having a high index of suspicion and assessing CD30 and anaplastic lymphoma kinase expression in all suspected T-cell neoplasms even though this rare condition is not necessarily expected.

Power conversion in a thermophotovoltaic (TPV) system can be accomplished with single p‐n junctions which are interconnected on‐wafer (monolithic interconnected module (MIM) approach) or off‐wafer (individual chip module approach) to form large area arrays. Using a MIM architecture, 0.6 eV InGaAs diodes grown lattice mismatched to InP have produced a power conversion efficiency of 23% and a power density of 0.65 W/cm2 at cell and radiator temperatures of 25°C and 1000°C, respectively. A shortcoming of a single p‐n junction is inefficient use of the incident spectrum due to over‐excitation losses from high, above bandgap energy photons. In order to overcome these losses, tandem TPV devices have been proposed which comprise two or more p‐n junctions of differing bandgaps. In this work we report on the growth, fabrication and characterization of InGaAsP/InGaAs (0.72/0.60 eV) tandem TPV diodes. Electrical measurements using a grey body source reveal an open circuit voltage of 0.504 V/cell and a fill factor of 72.3% at a short circuit current density of 0.069 A/cm2 and a cell temperature of 25°C.
