Bipolar depression versus unipolar depression: demographic and clinical differences

Middle East Current Psychiatry
Background Unipolar depression (UD) and bipolar depression (BD) are both characterized by depressive symptoms. In clinical practice, it is hard to distinguish between BD and UD. This often results in misdiagnosis of BD.

Low‐Frequency Oscillation Suppression of FDR Time‐Domain Diagnostic Waveforms for Cable Defects Based on Splicing Technology

High Voltage, EarlyView.
ABSTRACT A time domain pulse (TDP) based on the frequency domain reflectometry (FDR) method can be used to diagnose the insulation state of cable defects. However, because of the limitations of the FDR test instrument, the lack of a reflection coefficient spectrum (RCS) in the low‐frequency band (LFB) can result in low frequency oscillation in the time

Development of ± 550 kV DC GIS Basin Insulator

High Voltage, EarlyView.
ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.

Technology for Whom and for What? A Global South View of Tech Diplomacy

Global Policy, EarlyView.
ABSTRACT International politics is linked to its technical‐social character. Also, technology is socially constructed and thereby not entirely neutral or impartial. A tech‐driven geopolitical landscape has been a defining feature of contemporary world politics.
