The “America First” trade that surged in the immediate aftermath of Donald Trump’s electoral victory is on display again this week, with banks and smaller companies pushing the stock market ever higher yesterday. Despite some recent monetary-related jitters, investors are continuing to bet that Trump’s policy agenda -- including de-regulation and moves to boost domestic business over foreign competitors -- will add fresh fuel to the long-standing outperformance of US equities over world markets.

Long-term observations of the downward particle flux are mainly made by deep-moored sediment traps. In this thesis, impacts of mesoscale and submesoscale dynamics on the export of fast-sinking particles are investigated through backward and forward Lagrangian particle tracking experiments, using outputs from a 2-km resolution simulation of the North Atlantic Ocean over 7 years. The backward simulations show that mesoscale eddies can transport particles from hundreds of kilometers to sediment traps at the long-term observatory PAP site (16.5°W, 49.0°N). The variability of monthly particle sources shows a locally dominant eddy at the PAP site can significantly trap particles within a small region. Starting with a homogeneous seeding of particles at 200m, the forward simulations reveal that the seasonality and spatial variability of particle collections at 1000 m can result from the physical dynamics only. Clustering analysis of particles collected within a 200 x 200 km target zone suggests the seasonal variations of particle amounts In clusters active in winter-spring time are related to the mesoscale eddy activities and the development of fronts. In autumn and early winter, the local background flow (defined by low eddy and frontal activities) contributes most to the particle collection. The results demonstrates how mesoscale dynamics impact the heterogeneity of particle distribution, and thus collection in the deep ocean.

The “Bessent Bounce” didn't last long. Just one day after markets cheered Trump’s pick for Treasury secretary as a Wall Street-friendly choice, someone that might even tame the threats of harsh tariffs — the incoming president reminded everyone who the boss is. Trump cast the tariffs as necessary to clamp down on migrants and illegal drugs flowing across borders, and the market reaction was swift. The Canadian dollar dropped to a four-year low. The Mexican peso sank to its weakest since 2022.Whi

We propose a hybrid-system quantum battery model composed of cavity quantum electrodynamics (QED) and optomechanics, which is called a cavity-optomechanical quantum battery (COQB). The single two-level system (TLS) serves as a quantum battery, which is influenced by a mechanical oscillator through a cavity mode. When the TLS is coupled with cavity mode in the Jaynes-Cummings (JC) model and the initial number of photons is 0, it is impossible to achieve the charging and discharging process. We exhibit three different methods to achieve the feasibility of the COQB and analyze the role of oscillator in the different scenarios. In the closed system, the cavity mode and TLS are coupled in the Rabi model. For the two different environments, the cavity mode is coupled with a thermal bath or driven by a coherent driving field. The existence of an oscillator in both the closed and open dynamics demonstrates advantages in the stored energy and ergotropy.
