Arafin conducting research aimed at securing chiplet-based semiconductor manufacturing from untrusted supply chains

Md Tanvir Arafin, Assistant Professor, Cybersecurity Engineering, received funding for the project: "Securing Chiplet-based Semiconductor Manufacturing from Untrusted Supply Chains."
Monolithic integrated circuit (IC) design is reaching the physical limit to accommodate the ever-increasing demand of cramming more transistors in a chip. To address this, novel design primitives that move from monolithic design practices to heterogeneous integration of IC primitives in a 2.5 or 3D structure have emerged. For example, multiple chiplets (i.e., small, independent chips with defined functionalities) can be connected on a single substrate to create a high-density, high-performance integrated circuit. Chiplets usher in a new additive design paradigm in microelectronics, where chips from multiple vendors and process technologies are integrated efficiently with better yield and less wafer waste.
However, from a hardware security perspective, insecure supply chains introduce new vulnerabilities for chiplet-based technology, such as hardware Trojans and counterfeit tiles.
Hence, Arafin and his group will design provable trust embedding techniques for counterfeit chiplet detection in this project. Additionally, they will develop novel Trojan identification methods using the built-in-peer-testing capabilities of chiplets connected on a shared Universal Chiplet Interconnect Express (UCIe) bus.
Arafin received $50,000 from the Virginia Innovation Partnership Authority for this research. Funding began in Jan. 2024 and will end in Jan. 2025.

Low back pain is a major cause of disability around the globe, with more than 570 million people affected. In the United States alone, health care spending on low back pain was $134.5 billion between 1996 and 2016, and costs are increasing.
"The good news is that most episodes of back pain recover, and this is the case even if you have already had back pain for a couple of months," University of South Australia Professor Lorimer Moseley says.
"The bad news is that once you have had back pain for more than a few months, the chance ...

Organic mixed ionic–electronic conductors (OMIECs) are a highly sought-after class of materials for non-conventional applications, such as bioelectronics, neuromorphic computing, and bio-fuel cells, owing to their two-in-one electronic and ionic conduction properties. To ensure a much wider acceptance of these fascinating materials, there is a need to diversify their properties and develop techniques that allow application-specific tailoring of the features of OMIEC-based devices. A crucial aspect of this process is to develop strategies for evaluating the various properties of these ...

SPOKANE, Wash. – Researchers have identified a receptor protein known as CHRM1 as a key player in prostate cancer cells’ resistance to docetaxel, a commonly used chemotherapy drug to treat advanced cancer that has spread beyond the prostate. The discovery opens the door to new treatment strategies that could overcome this resistance. This could ultimately help extend the lives of those with prostate cancer, one of the leading causes of cancer deaths among men.
Led by a team of scientists at Washington State University, ...

About The Study: The results of this study including 2,261 and 1,940 infants ages 12 and 18 months, respectively, suggest that COVID-19 vaccination was safe during pregnancy from the perspective of infant neurodevelopment to 18 months of age. Additional longer-term research should be conducted to corroborate these findings and buttress clinical guidance with a strong evidence base.

Key takeaways:
A new 3D-printable material called “supramolecular ink” replaces costly scarce metals with inexpensive, Earth-abundant materials.
The organic material requires far less energy to manufacture than conventional methods.
It could also enhance the sustainability of 3D-printable wearable devices, lighting technologies, and luminescent art and sculpture.
A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has developed “supramolecular ink,” a new technology for use in OLED (organic light-emitting ...

COLUMBUS, Ohio – No matter how well children are prepared for kindergarten, their transition to the classroom during the first few months plays a key role in their success, a new study suggests.
Researchers found that kids who made a more successful transition in the first 10-14 weeks of kindergarten scored higher than others on tests of academic and social-behavioral skills at the end of the school year.
Important parts of the transition – what the researchers called a “big little leap” – included making new friends, ...
