Implementasi Hybrid DS/FH Spread Spectrum menggunakan DSK TMS302C6416T

open access: yesJurnal Teknik ITS, 2014
Spread spectrum adalah sebuah metode komunikasi dimana semua sinyal komunikasi disebar di seluruh spektrum frekuensi yang tersedia. Sinyal informasi akan ditebarkan pada seluruh pita frekuensi yang disediakan dan dilakukan secara acak.

A Chaos-Based Secure Direct-Sequence/Spread-Spectrum Communication System

open access: yesAbstract and Applied Analysis, 2013
This paper proposes a chaos-based secure direct-sequence/spread-spectrum (DS/SS) communication system which is based on a novel combination of the conventional DS/SS and chaos techniques.

A Two-Step Quantum Direct Communication Protocol Using Einstein-Podolsky-Rosen Pair Block

open access: yes, 2003
A protocol for quantum secure direct communication using blocks of EPR pairs is proposed. A set of ordered $N$ EPR pairs is used as a data block for sending secret message directly.

Molecular Methods for Rare Hemoglobinopathy Cases: First Brazilian Report of Pediatric Siblings with Hb O‐Arab and Alpha‐Thalassemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hemoglobinopathies are prevalent globally; diagnosis is complex in high genetic admixture populations like Brazil. We report, in two pediatric siblings, the first documented cases in Brazil of heterozygosity for hemoglobin (Hb) O‐Arab with coinheritance of α‐thalassemia (αα/−α4.2; −α3.7/−α4.2), resulting in microcytic and hypochromic anemia ...

On the Estimation of Synchronous Scramblers in Direct Sequence Spread Spectrum Systems

open access: yesIEEE Access, 2020
In a non-cooperative context, the receiver has no information about communication parameters; therefore, it must perform communication forensics, which is the process of identifying what information it can from the collected data.

TBP and SNAP50 transcription factors bind specifically to the Pr77 promoter sequence from trypanosomatid non-LTR retrotransposons

open access: yesParasites & Vectors, 2021
Background Trypanosomatid genomes are colonized by active and inactive mobile DNA elements, such as LINE, SINE-like, SIDER and DIRE retrotransposons. These elements all share a 77-nucleotide-long sequence at their 5′ ends, known as Pr77, which activates ...

Why Low-Mass Black-Hole Binaries Are Transient [PDF]

open access: yes, 1997
We consider transient behavior in low-mass X-ray binaries. In short-period neutron-star systems (orbital period less than ~ 1d) irradiation of the accretion disk by the central source suppresses this except at very low mass transfer rates.

Treatment Decision‐Making Roles and Preferences Among Adolescents and Young Adults With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Decision‐making (DM) dynamics between adolescents and young adults (AYAs) with cancer, parents, and oncologists remain underexplored in diverse populations. We examined cancer treatment DM preferences among an ethnically and socioeconomically diverse group of AYAs and their parents.

Optimal CDMA signatures: a finite-step approach [PDF]

open access: yes, 2005
A description of optimal sequences for direct-sequence code division multiple access is a byproduct of recent characterizations of the sum capacity. The paper restates the sequence design problem as an inverse singular value problem and shows that it can
