Differential distributed cayley space-time codes [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2009
We consider a wireless relay network with no channel information, which implements differential distributed space-time coding. We propose a coding strategy based on Cayley codes, which yields high data rate codes available for an arbitrary number of relay nodes.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Space-time acoustic coding metasurfaces with scattering reduction characteristics

open access: yesiScience
Summary: In recent years, constructing space-time joint modulation acoustic metasurfaces with harmonic manipulation capabilities to achieve excellent scattering reduction within three-dimensional (3D) space has remained a significant challenge.

KOMBINASI ORTHOGONAL SPACE TIME BLOCK CODING DAN BLOCK CHANNEL CODING UNTUK MENINGKATKAN KINERJA SISTEM ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING

open access: yesTeknologi dan Kejuruan, 2012
It is well known that space-time diversity using space-time coding (STC) is an effective technique to improve wireless communication performance. STC was designed for flat fading channel and consist of space-time trellis code (STTC) and space-time block ...

An Enumeration of the Equivalence Classes of Self-Dual Matrix Codes

open access: yes, 2015
As a result of their applications in network coding, space-time coding, and coding for criss-cross errors, matrix codes have garnered significant attention; in various contexts, these codes have also been termed rank-metric codes, space-time codes over ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

NKCC1: A key regulator of glioblastoma progression

open access: yesMolecular Oncology, EarlyView.
Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

Concatenated space-time block coding with asymmetric MPSK TCM

open access: yesTongxin xuebao, 2010
The field of concatenated space-time block coding (inner) with trellis coded modulation (outer) has recently attracted interest as a means of jointly considering the error correction coding gain and diversity gain possible without bandwidth expansion and

On the Capacity of Certain Space-Time Coding Schemes

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
We take a capacity view of a number of different space-time coding (STC) schemes. While the Shannon capacity of multiple-input multiple-output (MIMO) channels has been known for a number of years now, the attainment of these capacities remains a ...
