Achievability of nonlinear degrees of freedom in correlatively changing fading channels by Karzand, Mina, Zheng, Lizhong

“…Studying this mapping, it is shown that using nonlinear decoding algorithms for single input-multiple output (SIMO) and multiple input multiple output (MIMO) systems, extra numbers of degrees of freedom (DOF) are available. We call them the nonlinear degrees of freedom.…”

Coupling between the center of mass and relative degrees of freedom in a relativistic quantum composite and applications by Hagelstein, Peter L, Chaudhary, Irfan U.

“…If we consider the nucleus as a relativistic composite, then we are able to derive from a many-particle Dirac model a coupling between the center of mass motion and internal nuclear degrees of freedom. This interaction can be rotated out in free space, but has the potential to give rise to new physics when two or more nuclei exchange phonons with a common vibrational mode. …”

Quantum Composites: A Review, and New Results for Models for Condensed Matter Nuclear Science

“…In the nonrelativistic case there is a clean separation of center of mass and internal degrees of freedom, so that any coupling between them must occur through external field interactions. …”

Short-Packet Communications Over Multiple-Antenna Rayleigh-Fading Channels by Durisi, Giuseppe, Koch, Tobias, Ostman, Johan, Polyanskiy, Yury, Yang, Wei

“…Furthermore, our bounds reveal the existence of a tradeoff between the rate gain obtainable by spreading each codeword over all available time-frequency-spatial degrees of freedom, and the rate loss caused by the need of estimating the fading coefficients over these degrees of freedom. …”

Recognizing Interspersed sketches quickly by Hammond, Tracy A., Davis, Randall

“…When allowing users to sketch as they would naturally, users may draw shapes in an interspersed manner, starting a second shape before finishing the first. In order to provide freedom to draw interspersed shapes, an exponential combination of subshapes must be considered. …”

Random linear network coding for time division duplexing: energy analysis by Lucani, Daniel Enrique, Medard, Muriel, Stojanovic, Milica

“…The sender transmits coded data packets back-to-back before stopping to wait for the receiver to acknowledge the number of degrees of freedom, if any, that are required to decode correctly the information. …”

Random linear network coding for time division duplexing: When to stop talking and start listening by Medard, Muriel, Lucani, Daniel Enrique, Stojanovic, Milica

“…This number depends on the latency, probabilities of packet erasure and ACK erasure, and the number of degrees of freedom that the receiver requires to decode the data. …”

Phase space trajectories generated under coupling between a dynamic system and a thermal reservoir by Sinha, Dhiraj

“…The new perspective can help in developing a closed form expression of heat and work at microscopic dimensions with a few degrees of freedom. We also present a novel mathematical model of thermal reservoir as a dynamic system described using a transfer function comprising of a set of zeros. …”

Trace formulation for photonic inverse design with incoherent sources by Yao, Wenjie, Verdugo, Francesc, Christiansen, Rasmus E., Johnson, Steven G.

“…We present a trace formulation of incoherent emission that can be efficiently combined with inverse design, even for topology optimization over thousands of design degrees of freedom. Our formulation includes previous reciprocity-based approaches, limited to a few output channels (e.g., normal emission), as special cases but generalizes to a continuum of emission directions by exploiting the low-rank structure of emission problems. …”

Anomalies in fracture experiments, and energy exchange between vibrations and nuclei by Hagelstein, Peter L., Chaudhary, Irfan U.

“…The fracture anomalies in this picture arise naturally as a result of the relevativistic interaction between vibrations and internal nuclear degrees of freedom, and up-conversion of vibrational quanta. …”

Random Access Heterogeneous Mimo Networks by Lin, Kate Ching-Ju, Gollakota, Shyamnath, Katabi, Dina

“…This paper presents the design and implementation of 802.11n+, a fully distributed random access protocol for MIMO networks. 802.11n+ allows nodes that differ in the number of antennas to contend not just for time, but also for the degrees of freedom provided by multiple antennas. We show that even when the medium is already occupied by some nodes, nodes with more antennas can transmit concurrently without harming the ongoing transmissions. …”
