A VHDL Model for Implementation of MD5 Hash Algorithm [PDF]

open access: yesEngineering and Technology Journal, 2013
With the increase of the amount of data and users in the information systems, the requirement of data integrity is needed to be improved as well, so the work has become necessary independently.

Predictive ecological niche model for Cinnamomum parthenoxylon (Jack) Meisn. (Lauraceae) from Last Glacial Maximum to future in Vietnam [PDF]

open access: yesBiodiversity Data Journal
Cinnamomum parthenoxylon (Jack) Meisn. is a tree in genus Cinnamomum that has been facing global threats due to forest degradation and habitat fragmentation. Many recent studies aim to describe habitats and assess population and species genetic diversity

CR-MAC: Cooperative Relaying MAC Protocol for VANETs

open access: yes2019 Scientific Meeting on Electrical-Electronics & Biomedical Engineering and Computer Science (EBBT), 2019
In this paper, a novel cooperative relaying medium access control (CR-MAC) protocol is proposed for vehicular ad hoc networks (VANETs). Three data transmission modes have been offered to increase the throughput which are direct transmission (DT), cooperative relaying (CR) and multi-hop relaying (MHR).

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

An analytical model of contention in wireless sensor networks using tree routing

open access: yesTạp chí Khoa học và Công nghệ
Presently, the focus of current research on Wireless Sensor Networks (WSNs) is predominantly on contention at the MAC layer, overlooking the traffic characteristics of upper-layer traffic, especially the interaction with the routing traffic.

Application of the mode-shape expansion based on model order reduction methods to a composite structure

open access: yesOpen Engineering, 2017
The application of different mode-shape expansion (MSE) methods to a CFRP based on model order reduction (MOR) and component mode synthesis (CMS) methods is evaluated combining the updated stiffness parameters of the full FE model obtained with a mix ...

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.
