Is the cyclic prefix necessary?
, 2006 We show that one can do away with the cyclic prefix (CP) for SC-FDE and OFDM at the cost of a moderate increase in the complexity of a DFT-based receiver.

c-trie++: A Dynamic Trie Tailored for Fast Prefix Searches
, 2020 Given a dynamic set $K$ of $k$ strings of total length $n$ whose characters are drawn from an alphabet of size $\sigma$, a keyword dictionary is a data structure built on $K$ that provides locate, prefix search, and update operations on $K$.

Prefix Codes for Power Laws with Countable Support
, 2007 In prefix coding over an infinite alphabet, methods that consider specific distributions generally consider those that decline more quickly than a power law (e.g., Golomb coding).

Prefix-Projection Global Constraint for Sequential Pattern Mining [PDF]
, 2015 Sequential pattern mining under constraints is a challenging data mining task. Many efficient ad hoc methods have been developed for mining sequential patterns, but they are all suffering from a lack of genericity.

An adaptive prefix-assignment technique for symmetry reduction
, 2018 This paper presents a technique for symmetry reduction that adaptively assigns a prefix of variables in a system of constraints so that the generated prefix-assignments are pairwise nonisomorphic under the action of the symmetry group of the system.

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
FEBS Letters, EarlyView.This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Goal-Source Asymmetry and Russian Spatial Prefixes
Nordlyd: Tromsø University Working Papers on Language & Linguistics, 2007 In this paper, I draw on data from Russian to argue for the asymmetry between Goal and Source prepositional phrases. Source prepositional phrases are structurally ambiguous; they can occur both as arguments and adjuncts in certain syntactic contexts ...

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression
Molecular Oncology, EarlyView.Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.

Rate of prefix-free codes in LQG control systems [PDF]
International Symposium on Information Theory, 2016 In this paper, we consider a discrete time linear quadratic Gaussian (LQG) control problem in which state information of the plant is encoded in a variable-length binary codeword at every time step, and a control input is determined based on the ...
