Lamin B1 safeguards the B cell genome and shapes lymphoma outcome

open access: yesHemaSphere, Volume 10, Issue 6, June 2026.
Abstract Lamin B1 is a structural component of the nuclear lamina that participates in genome organization and transcriptional control. During adaptive immune responses, B lymphocytes in germinal centers (GCs) undergo clonal expansion and programmed DNA damage at immunoglobulin loci, while simultaneously downregulating Lamin B1.

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems

open access: yesInternational Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.
This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...

Development of a Low Bit Error Rate (BER) Coding Technique for Underwater Communication

open access: yes
Underwater communication plays a crucial role in transmitting data below the water’s surface. Maintaining the quality of transmitted information is essential, as underwater channels are highly affected by speckle noise and multipath currents, leading to Doppler frequency variations and changing node distances.

Design and Implementation of a Chaotic Scheme in Additive White Gaussian Noise Channel

open access: yesJournal of Computer Networks and Communications, 2016
A new chaotic scheme named Flipped Chaotic On-Off Keying (FCOOK) is proposed for binary transmission. In FCOOK, the low correlation value between the stationary signal and its mirrored version is utilized.

Improvement of Bit Error Rate (BER) in Telemetry Radio Link of Satellite LEO Using MIMO Technique

open access: yesفصلنامه علوم و فناوری فضایی, 2012
After setteling the LEO satellite in the given circuit, the ground station needs to communicate with it for the received of information and control of its subsystems. Due to the fact that satellite communication channels are influenced by shadowing conditions, if a line of sight (LOS) signal exists between the receiver and the transmitter, then the ...
