A case of schizophrenia with Parkinson's disease: Reduced dopamine transporter binding in unilateral striatum and normal uptake pattern of 123I‐MIBG myocardial scintigraphy

Psychiatry and Clinical Neurosciences Reports, Volume 4, Issue 3, September 2025.
A case of schizophrenia with Parkinson's disease with reduced dopamine transporter binding in unilateral striatum and normal uptake pattern of 123I meta‐iodo benzylguanidine myocardial scintigraphy was presented. Prompt and accurate diagnosis through detailed clinical evaluation and appropriate imaging studies is crucial for the effective management of

Short interpregnancy interval following reproductive coercion: A prospective cohort study of pregnant Ethiopian women

Pregnancy, Volume 1, Issue 5, September 2025.
Abstract Background Short interpregnancy intervals (IPIs) (< 12 months) remain a public health concern in low‐ and middle‐income countries due to their association with adverse maternal and neonatal outcomes. Reproductive coercion (RC), which involves intimate partner behaviors that interfere with women's reproductive decisions, undermines autonomy ...

Application of Motion Sensors for Beam-Tracking of Mobile Stations in mmWave Communication Systems

Sensors, 2014
In a millimeter wave (mmWave) communication system with transmit/receive (Tx/Rx) beamforming antennas, small variation in device behavior or an environmental change can destroy beam alignment, resulting in power loss in the received signal.
