1. xTern: Energy-Efficient Ternary Neural Network Inference on RISC-V-Based Edge Systems 

   Rutishauser, Georg; Mihali, Joan; Scherer, Moritz; et al. (2024)

   2024 IEEE 35TH INTERNATIONAL CONFERENCE ON APPLICATION-SPECIFIC SYSTEMS, ARCHITECTURES AND PROCESSORS, ASAP 2024

   Ternary neural networks (TNNs) offer a superior accuracy-energy trade-off compared to binary neural networks. However, until now, they have required specialized accelerators to realize their efficiency potential, which has hindered widespread adoption. To address this, we present xTern, a lightweight extension of the RISC-V instruction set architecture (ISA) targeted at accelerating TNN inference on general-purpose cores. To complement ...

2. Spatzformer: An Efficient Reconfigurable Dual-Core RISC-V V Cluster for Mixed Scalar-Vector Workloads 

   Perotti, Matteo; Raeber, Michele; Sinigaglia, Mattia; et al. (2024)

   2024 IEEE 35TH INTERNATIONAL CONFERENCE ON APPLICATION-SPECIFIC SYSTEMS, ARCHITECTURES AND PROCESSORS, ASAP 2024

   Multi-core vector processor architectures excel in handling computationally intensive vectorizable tasks but struggle to achieve optimal resource utilization when facing sequential and control tasks that cannot be vectorized. This work presents Spatzformer, the first reconfigurable RISC-V V (RVV) architecture developed from a baseline open-source dual-core cluster based on Snitch scalar cores augmented with compact Spatz vector units. ...

3. Fluid confinement within a branched polymer structure enhances tribological performance of a poly(2-methacryloyloxyethyl phosphorylcholine)-surface-modified contact lens 

   Sharma, Vinay; Shi, Xinfeng Charlie; Yao, George; et al. (2024)

   Royal Society Open Science

   The poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC)-modified, silicone hydrogel, contact lens (CL) material lehfilcon A has previously been demonstrated to have a lubricious, antifouling and ultra-soft surface. This study provides confirmatory identification of the outer polymer structures on this CL surface as branched PMPC structures. It further aims to understand their role in providing enhanced tribological performance via fluid ...

4. Posterior Glenoid Bone Grafting in the Setting of Excessive Glenoid Retroversion Does Not Provide Adequate Stability in a Cadaveric Posterior Instability Model 

   Ernstbrunner, Lukas; Paszicsnyek, Alexander; Ker, Andrew M.; et al. (2024)

   The American Journal of Sports Medicine

   Background: Excessive glenoid retroversion is a known risk factor for posterior shoulder instability and failure after soft tissue stabilization procedures. Whether excessive glenoid retroversion is a risk factor for failure after posterior glenoid bone grafting is unknown. Purpose: To evaluate the biomechanical effectiveness of posterior iliac crest bone grafting (ICBG) for posterior shoulder instability with increasing glenoid retroversion. ...

5. Surgeon-Scientists Going Extinct 

   Pfister, Matthias; Li, Zhihao; Huwyler, Florian; et al. (2024)

   Annals of Surgery

   Objective:To define the concept of surgeon-scientists and identify the root causes of their decline in number and impact. The secondary aim was to provide actionable remedies.Background:Surgeons who conduct research in addition to patient care are referred to as "surgeon-scientists." While their value to society remains undisputed, their numbers and associated impact have been plunging. While reasons have been well identified along with ...
