Optimization of parameters for diesel shaft speed control system [PDF]
This work presents a fuel supply electronic control system (model ESUVT.01) developed by Dizelavtomatika (Saratov) for the D50 (6 CHN 31.8/33) locomotive diesel engine manufactured by Penzadieselmash. In this system, the fuel supply process is controlled

Who Supplies PPP Loans (and Does It Matter)? Banks, Relationships, and the COVID Crisis
We analyze the bank supply of credit under the Paycheck Protection Program (PPP). The literature emphasizes relationships as a means to improve lender information, which helps banks manage credit risk.

PPP/PPP‐RTK open formats: Overview, comparison, and proposal for an interoperable message
This paper presents and reviews the main existing open specifications for PPP/PPP-RTK services, including satellite navigation providers (QZSS, Galileo, BeiDou, GLONASS) and other industrial or scientific initiatives (RTCM, SAP-CORDA, 3GPP, IGS).

Charmless Final States and S--D-wave mixing in the $ψ''$ [PDF]
The $\ppp = \psi(3770)$ resonance is expected to be mainly $c \bar c(1^3D_1)$, but tensor forces and coupling to charmed particle pairs can mix it with $\pp(2^3S_1)$ and other states. Implications of this mixing for decays of $\ppp$ to non-charmed final states are discussed.

Charmless $B\to PPP$ Decays: the Fully-Antisymmetric Final State [PDF]
Under flavor $SU(3)$ symmetry (SU(3)$_F$), the final-state particles in $B\to PPP$ decays ($P$ is a pseudoscalar meson) are treated as identical, and the $PPP$ must be in a fully-symmetric (FS) state, a fully-antisymmetric (FA) state, or in one of four mixed states. In this paper, we present the formalism for the FA states.
