Let me start with praise for the paper and also introduce the structure of my comments. The paper by Misina and Tkacz is part of recent, broader literature investigating how asset prices and other financial variables can help document and predict financial stress and financial distress. Clearly, since we have faced the largest financial crisis in advanced countries since the Great Depression, n...

Waves of any kinds, including sound waves and light waves, can interfere constructively or destructively when they are overlapped, allowing for myriad applications. However, unlike continuous waves of a single frequency, interference of photoacoustic pulses is often overlooked because of their broadband characteristics and short pulse durations. Here, we study cancellation of two symmetric phot...

Repeated exposure to sugary, fatty, and salty foods often enhances their appeal. However, it is unknown if exposure influences learned palatability of foods typically promoted as part of a healthy diet. We tested whether the palatability of pulse containing foods provided during a weight loss intervention which were particularly high in fiber and low in energy density would increase with repeat...

Recent research indicates that tinnitus is related to alterations of neural networks including temporal, parietal, and prefrontal brain regions. The current study examines a rTMS protocol which targets three central nodes of these networks in a two-arm randomized parallel group trial. Overall, 49 patients with chronic tinnitus were randomized to receive either triple-site stimulation (left dors...

History taking and physical examination is the cornerstone of medical diagnosis as will lead to correct diagnosis 90% of the time. We report a case of a 30-year-old black African man with lymph node tuberculosis diagnosed one year and six months later after onset of symptoms and signs. Clinicians especially those in resource-limited settings should go in for thorough history taking and complete...

OBJECTIVE Risk taking affects human behavior in general and decisions in medicine in particular. We used game theory to assess physicians' risk-taking tendencies. METHODS Physicians were recruited to the study by advertisement. It was explained that they would receive a sum of money for correct prediction of the flipping of a coin. They could try to sell their opportunity to flip the coin for...

Acoustic stimulation methods applied during sleep in young adults can increase slow wave activity (SWA) and improve sleep-dependent memory retention. It is unknown whether this approach enhances SWA and memory in older adults, who generally have reduced SWA compared to younger adults. Additionally, older adults are at risk for age-related cognitive impairment and therefore may benefit from non-...

In this study, we used shape memory alloys as actuators to build a biomorphic robot which can imitate the motion of an earthworm. The robot can be used to explore in a narrow space. Therefore we chose shape memory alloys as actuators. Because of the small deformation of a wire shape memory alloy, spiral shape memory alloys are selected and installed both on the X axis and Y axis (each axis havi...

Ultra-wideband (UWB) has received significant attention for applications in target positioning and wireless communications recently. The extremely short pulses in turn generate a very wide bandwidth and offer several advantages, such as large throughput, covertness, robustness to jamming, lower power, and coexistence with current radio services. UWB not only can transmit a huge amount of data o...

Parental depression is a significant risk factor for adolescents' engagement in risk taking. Yet the neural processes that mediate the link between parental depression and adolescents' functioning remain unknown. Using a longitudinal functional magnetic resonance imaging design, we investigated how parental depression is associated with changes in adolescents' neural reactivity to rewards durin...
