Table 1_Laboratory comparison of consumer-grade and research-established wearables for monitoring heart rate, body temperature, and physical acitivity in sub-Saharan Africa.docx by Stefan Mendt (834379)

“…We statistically compared the data agreement using Pearson’s correlation r, Lin’s concordance correlation coefficient (LCCC), Bland-Altman method, and mean absolute percentage error.</p>Results<p>A good agreement was found between the wrist-worn Withings Pulse HR (consumer-grade) and the chest-worn Faros Bittium 180 in measuring heart rate while sitting, standing, and slow walking on a treadmill at a speed of 2.7 km/h (r ≥ 0.82, |bias| ≤ 3.1 bpm), but this decreased with increasing speed (r ≤ 0.33, |bias| ≤ 11.7 bpm). …”

Optical Inline Interferometer for Enhanced Low-Field Detection via Electric-Field Induced Second Harmonic Generation by Jean-Baptiste Billeau (18886201)

“…Furthermore, we successfully measured an electric field as low as 32 V/cm with an SNR of 7.4 during 0.15 s measurement time, estimating an unprecedented detection limit of 1.7 V/(cm Hz^0.5). Our work represents a significant step toward real-time, high-precision diagnostics of electric fields in complex plasma environments, electric field amplitude fluctuations can influence reactive species' generation and overall process efficiency.…”

PDLB - Balance Sheet by Nguyen Linh (19516642)

“…However, there are reasons to think management may be preparing to sell the bank:</p><ul><li>They did a second step conversion in January 2022. Only the optionality to sell the bank would motivate this step, as the bank didn’t need the capital, and the conversion increases management’s susceptibility to activist investors. …”
