Introduction: Apart from saving lives, mammography screening programs (MSP) are expected to reduce negative side effects of treatment by detecting cancer earlier, when it is more responsive to less aggressive treatment. This study compared quality of life (QoL) among women with breast cancers that were detected either by screening mammography, as interval cancers, or clinically among women not participating in the MSP.
Methods: Retrospective study of first-ever invasive breast cancers detected among MSP-eligible women aged 50-69 years between 2006 and 2012 in Münster, Germany. EORTC QLQ-C30 and -BR23 questionnaires were mailed to 1,399 cases still alive in 2015 (response rate 64.1%).
Results: Women's responses were obtained on average 6.1 years after diagnosis. Mean crude and age-adjusted scores for overall QoL, breast and body image (BBI), and five functional scales (FS) were comparable between groups of detection mode. Clearly lower adjusted means for most scores were observed in women with interval cancers, if time since diagnosis was less than 5 years. Cases younger than 60 years showed lower values for some FS, particularly among interval and screen-detected cases.
Discussion/conclusion: In summary, cases with breast cancer showed health-related score values that were similar to the general population of the same age. There was also no indication that mode of detection markedly influenced these scores. However, after adjusting for tumor stage and other influential factors, screening participants appeared more susceptible to score declines after a diagnosis of cancer than non-participants.

The utilization of dual-working-electrode mode of interdigitated array (IDA) electrodes and other two-electrode systems has revolutionized electrochemical detection by enabling the simultaneous and independent detection of two species, accompanied by the exhibition of unique characteristics. In contrast to conventional dual-potential electrodes, such as the rotating ring disk electrodes (RRDE), IDA electrodes demonstrate analogous yet vastly improved performance, characterized by remarkable collection efficiency and sensitivity. Notably, due to the distinctive microscale structure of IDA electrode, the special "feedback" effect makes IDA a unique signal amplifier.

We present direct frequency comb cavity ring-down spectroscopy with Vernier filtering as a straightforward approach to sensitive and multiplexed trace gas detection. The high finesse cavity acts both to extend the interaction length with the sample and as a spectral filter, alleviating the need for dispersive elements or an interferometer. In this demonstration, a free running interband cascade laser was used to generate a comb centered at 3.

The time-resolved detection of mid- to far-infrared electric fields absorbed and emitted by molecules is among the most sensitive spectroscopic approaches and has the potential to transform sensing in fields such as security screening, quality control, and medical diagnostics. However, the sensitivity of the standard detection approach, which relies on encoding the far-infrared electric field into amplitude modulation of a visible or near-infrared probe laser pulse, is limited by the shot noise of the latter. This constraint cannot be overcome without using a quantum resource.

For surveillance video management in university laboratories, issues such as occlusion and low-resolution face capture often arise. Traditional face recognition algorithms are typically static and rely heavily on clear images, resulting in inaccurate recognition for low-resolution, small-sized faces. To address the challenges of occlusion and low-resolution person identification, this paper proposes a new face recognition framework by reconstructing Retinaface-Resnet and combining it with Quality-Adaptive Margin (adaface).

The detection of low-molecular-weight biomarkers is essential for diagnosing and managing various diseases, including neurodegenerative conditions such as Alzheimer's disease. A biomarker's low molecular weight is a challenge for label-free optical modalities, as the phase change they detect is directly proportional to the mass bound on the sensor's surface. To address this challenge, we used a resonant Young's slit interferometer geometry and implemented several innovations, such as phase noise matching and optimisation of the fringe spacing, to maximise the signal-to-noise ratio.
