Simple technique to avoid inadvertent upside-down implantation of multipiece IOL with injector [PDF]
BMJ Case Reports, 2021 The evolution of multipiece intraocular lenses (IOLs) has provided the option of sulcus implantation in situations wherein the bag implantation is not feasible. Multipiece IOLs are implanted in eyes with an intact anterior capsular rim and posterior capsular tear or with pre-existing ...

On the robustness of ultra-high voltage 4H-SiC IGBTs with an optimized retrograde p-well [PDF]
, 2019 The robustness of ultra-high voltage (>10kV) SiC IGBTs comprising of an optimized retrograde p-well is investigated. Under extensive TCAD simulations, we show that in addition to offering a robust control on threshold voltage and eliminating punch ...

Thalamic inputs to dorsomedial striatum are involved in inhibitory control: evidence from the five-choice serial reaction time task in rats [PDF]
, 2017 Rationale Corticostriatal circuits are widely implicated in the top-down control of attention including inhibitory control and behavioural flexibility. However, recent neurophysiological evidence also suggests a role for thalamic inputs to striatum in
