New emission inventory reveals termination of global dioxin declining trend
Journal of Hazardous Materials, 2022Accurate estimates of spatiotemporally resolved Polychlorinated dibenzo-p-dioxins (PCDD/Fs, or dioxins) emissions are critical for understanding their environmental fate and associated health risks. In this study, by utilizing an empirical regression model for PCDD/Fs emissions, we developed a global emission inventory for 17 toxic PCDD/Fs congeners ...

Positron Emission Tomography Can Reveal Abdominal Periaortitis
Clinical Nuclear Medicine, 2002The authors describe a 58-year-old man with fatigue, anorexia, weight loss, and pain in the lumbar region and lower abdomen. Nine years earlier, he had a myocardial infarction, and had recently recovered from a transient ischemic attack. Physical examination showed xanthelasma and bruits over both iliac arteries, with weak distal pulses.

Revealing deterministic structures in click-evoked otoacoustic emissions
Journal of Applied Physiology, 2000Click-evoked otoacoustic emissions (CEOAEs) were studied by means of recurrence quantification analysis (RQA) and were found to be endowed with a relevant amount of deterministic structuring. Such a structure showed highly significant correlation with the clinical evaluation of the signal over a data set including 56 signals.

Positron emission tomography reveals a leiomyosarcoma causing proteinuria
Clinical Nephrology, 2003Obstruction of the renal veins may result in proteinuria and is frequently caused by thrombosis or tumorous processes. Since thrombosis and malignancy may occur simultaneously in the venous outflow of the kidneys, search for an underlying intraluminal tumor may be impeded by extensive thrombosis in the lumen of renal and caval veins. We report the case

Revealing the trap emission in graphene-based nanostructures
Carbon, 2019Abstract Enhancing the photoconversion efficiency of graphene-based nanomaterials, especially graphene quantum dots (GQDs) and graphene nanoribbons (GNRs), has been a long pursued interest in diverse optical applications. Though chemical modification has shown its effectiveness to enhance the photoluminescence efficiencies of these materials, an ...

Revealing SRAM memory content using spontaneous photon emission
2016 IEEE 34th VLSI Test Symposium (VTS), 2016This paper presents a novel methodology that allows one to reveal SRAM memory content by observing the spontaneous photon emission collected from the backside of the chip. This method is based on our proposed tester-based optical methodology [1] that combines different test patterns, time-integrated and time-resolved emission measurements to localize ...

Phonon Line Emission Revealed by Self-Assembly of Colloidal Nanoplatelets
ACS Nano, 2013We show that colloidal nanoplatelets can self-assemble to form a 1D superlattice. When self-assembled, an additional emission line appears in the photoluminescence spectrum at low temperatures. This emission line is a collective effect, greatly enhanced when the NPLs are self-assembled.
