Proactive Traffic-Adaptive Tuning of Contention Window for Wireless Sensor Network Medium-Access Control Protocol [PDF]

open access: yes, 2009
The ongoing advances in wireless networks have further expanded the boundaries to the new and challenging area of Wireless Sensor Networks (WSN). Unique properties of sensor nodes such as limited energy storage, constrained processing capabilities and

Fourier Optics in the Classroom

open access: yes, 2018
Borrowing methods and formulas from Prof. Goodman's classic Introduction to Fourier Optics textbook [1], I have developed a software package [2] that has been used in both industrial research and classroom teaching [3]. This paper briefly describes a few

3D SCAFFOLDS BY 3D BIOPRINTING

open access: yesInternational Journal of Current Pharmaceutical Research, 2023
When it comes to tissue engineering, 3D printing is a crucial technique for creating intricate constructions using biocompatible materials, cells, and supporting elements. The concept of "3D bioprinting" is concerning 3D printing, which may be used to design personalised implants, paving the way for new bio-manufacturing methods.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

3D Textured Model Encryption via 3D Lu Chaotic Mapping

open access: yes, 2017
In the coming Virtual/Augmented Reality (VR/AR) era, 3D contents will be popularized just as images and videos today. The security and privacy of these 3D contents should be taken into consideration.

An $$ \mathcal{N}=1 $$ 3d-3d correspondence [PDF]

open access: yesJournal of High Energy Physics, 2018
AbstractM5-branes on an associative three-cycleM3in aG2-holonomy manifold give rise to a 3d$$ \mathcal{N}=1 $$N=1supersymmetric gauge theory,$$ {T}_{\mathcal{N}=1}\left[{M}_3\right] $$TN=1M3. We propose an$$ \mathcal{N}=1 $$N=13d-3d correspondence, based on two observables of these theories: the Witten index and theS3-partition function.

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS 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 ...

Assessment of Right Ventricular-Arterial Coupling by Echocardiography in Patients with Right Ventricular Pressure and Volume Overload

open access: yesReviews in Cardiovascular Medicine, 2023
Background: Right ventricle-pulmonary arterial (RV-PA) coupling is considered the gold standard for assessing right ventricular (RV) function and can be evaluated noninvasively by echocardiography. The ratios of tricuspid annular plane systolic excursion/

SimpleRecon: 3D Reconstruction Without 3D Convolutions

open access: yes, 2022
Traditionally, 3D indoor scene reconstruction from posed images happens in two phases: per-image depth estimation, followed by depth merging and surface reconstruction. Recently, a family of methods have emerged that perform reconstruction directly in final 3D volumetric feature space.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.
