This paper presents ultra-wideband 18.2-42.0 GHz LC injection-locked frequency doubler (ILFD) with transformer inputs. To expand the locking range, proposed ILFD incorporates connected to source of gain-cell transistor obtain high linearity input circuitry, moreover, matching shifts from free-run oscillator. The measured maximum range exhibited 79.1% 18.2 42.0 output at 0 dBm power and locked p...

We adopt the deep learning method CASI-3D (Convolutional Approach to Structure Identification-3D) systemically identify protostellar outflows in 12CO and 13CO observations of nearby molecular clouds, Ophiuchus, Taurus, Perseus Orion. The total outflow masses are 267 Msun, 795 1305 Msun 6332 for Orion, respectively. show mass each cloud is linearly proportional number young stellar objects. esti...

Abstract Circulating current has been an inherent feature of modular multilevel converters (MMC), which results in second-order harmonics on the arms currents. If not properly controlled, circulating can affect lifetime and reliability a converter by increasing loading, loss distribution, junction temperature its semiconductor devices. This paper proposes controlled injection as means improving...

Subsurface drip irrigation (SDI) can substantially reduce the amount of irrigation water needed for corn production. However, corn yields need to be improved to offset the initial cost of drip installation. Air-injection is at least potentially applicable to the (SDI) system. However, the vertical stream of emitted air moving above the emitter outlet directly toward the surface creates a chimne...

ABSTRACT The bipolar, non-thermal, high-latitude lobes known as the Fermi bubbles (FBs) are thought to originate from a massive energy release near Galactic Centre (GC). We constrain FB engine and circumgalactic medium (CGM) by analytically numerically modelling edges strong forward shocks, inferred recent observations. A non-directed produces shocks too spherical account for observations even ...

Abstract The specifics of the simulated injection choices in case stratospheric aerosol injections (SAI) are part crucial context necessary for meaningfully discussing impacts that a deployment SAI would have on planet. One main is desired amount cooling aiming to achieve. Previous simulations usually either fixed injection, resulting warming being offset, or specified one target temperature, s...
