Photonic Generation and Free-Space Distribution of Millimeter Waves for Portable Optical Clocks

Dylan Meyer, ALEXANDER R. LIND, William D. Groman, Hero Trent et autres

Robust and portable optical clocks promise to bring sub-picosecond timing instability to smaller form factors, offering possible performance improvements and new scenarios for positioning and navigation, radar technologies, and experiments probing fundamental physics. However, there are currently limited methods suitable for broadly …

Dual Laser Self-Injection Locking to a Micro Fabry-Perot for Low Phase Noise Millimeter-wave Generation

William D. Groman, Naijun Jin, Haotian Cheng, Dylan Meyer et autres

Low-noise and accessible millimeter-wave sources are critical for emergent telecommunications, radar and sensing applications. Current limitations to realizing low-noise, deployable millimeter-wave systems include size, weight, and power (SWaP) requirements, along with complex operating principles. In this paper we provide a compact photonic …

Risk of celiac disease, type 1 diabetes, and thyroid disease autoimmunity during the SARS-CoV-2 pandemic in South of Sweden: insights from the TRIAD study

ALEXANDER R. LIND, Maria Naredi Scherman, Samia Hamdan, Daniel Agardh

Recent studies have implied an increased incidence of autoimmune diseases following the SARS-CoV-2 pandemic. The objective was to determine if SARS-CoV-2 infections were associated with celiac disease (CD), type 1 diabetes (T1D), and autoimmune thyroid disease (AITD) autoantibodies in a population-based screening …

Inflammatory Immune Markers Associated With Thyroid Peroxidase Autoantibodies in Children Diagnosed With Both Type 1 Diabetes and Celiac Disease

Emanuel Fryk, Andrea Tompa, ALEXANDER R. LIND, Rasmus Bennet et autres

Autoimmune thyroid disease (AITD) is associated with other autoimmune endocrine diseases such as type 1 diabetes (T1D) and celiac disease (CeD). Thyroid peroxidase autoantibodies (TPOA) are biomarkers of AITD but may also occur in patients with other autoimmune diseases. We examined cross-sectional …

Diabetes, Celiac, and Thyroid‐Related Autoantibodies in HLA Genotyped Ethiopian Children and Adolescents With Type 1 Diabetes: A Cross‐Sectional Study

Adugna Negussie Gudeta, ALEXANDER R. LIND, Alemayehu Girma, Johanna Lempainen et autres

Background: Autoantibodies against β‐cell components in the pancreatic islets of Langerhans are characteristic of type 1 diabetes (T1D). The genetic and autoimmune determinants of type 1 diabetes (T1D) in Ethiopians are not yet thoroughly characterized, with studies indicating a lower occurrence of …

Dual Laser Self-Injection Locking to a Micro-Fabricated Fabry-Perot for Low Noise Millimeter-wave Generation

William D. Groman, Naijun Jin, Dylan Meyer, Haotian Cheng et autres

We self-injection lock two diode lasers to a 4 mm long, micro-fabricated Fabry-Perot cavity. Heterodyning the lasers generates a 111.45 GHz signal with phase noise of -148 dBc/Hz at 1 MHz frequency offset.

Photonic millimeter-wave generation beyond the cavity thermal limit

William D. Groman, Igor S. Kudelin, ALEXANDER R. LIND, Dahyeon Lee et autres

Next-generation communications, radar, and navigation systems will extend and exploit the higher bandwidth of the millimeter-wave domain for increased communication data rates as well as radar with higher sensitivity and increased spatial resolution. However, realizing these advantages will require the generation of …

Type 1 diabetes, celiac disease, and autoimmune thyroiditis autoantibodies in population-based type 2 diabetes patients

ALEXANDER R. LIND, Tsai Cheng-ting, Jendle Johan

Aims: The study aims were to determine autoantibodies associated with type 1 diabetes (T1D), celiac disease (CD) and autoimmune thyroid disease (AITD) in individuals living with type 2 diabetes (T2D) compared to T1D and matched controls. Methods: Individuals with T1D and T2D …

High‐resolution HLA sequencing and hypocretin receptor 2 autoantibodies in narcolepsy type 1 and type 2

Samia Hamdan, Pontus Wasling, ALEXANDER R. LIND

Abstract Narcolepsy is a sleep disorder caused by an apparent degeneration of orexin/hypocretin neurons in the lateral hypothalamic area and a subsequent decrease in orexin/hypocretin levels in the cerebrospinal fluid. Narcolepsy is classified into type 1 (NT1) and type 2 (NT2). While …

Childhood screening for type 1 diabetes comparing automated multiplex Antibody Detection by Agglutination-PCR (ADAP) with single plex islet autoantibody radiobinding assays

ALEXANDER R. LIND, Eva Freyhult, Felipe de Jesus Cortez, Anita Ramelius et autres

Background Two or more autoantibodies against either insulin (IAA), glutamic acid decarboxylase (GADA), islet antigen-2 (IA-2A) or zinc transporter 8 (ZnT8A) denote stage 1 (normoglycemia) or stage 2 (dysglycemia) type 1 diabetes prior to stage 3 type 1 diabetes. Automated multiplex Antibody …
