1. Failing to Hash Into Supersingular Isogeny Graphs 

   Booher, Jeremy; Bowden, Ross; Doliskani, Javad; et al. (2024)

   COMPUTER JOURNAL

   An important open problem in supersingular isogeny-based cryptography is to produce, without a trusted authority, concrete examples of 'hard supersingular curves' that is equations for supersingular curves for which computing the endomorphism ring is as difficult as it is for random supersingular curves. A related open problem is to produce a hash function to the vertices of the supersingular $\ell $ -isogeny graph, which does not reveal ...

2. A Jitter Programmable Digital Bang-Bang PLL Using PVT-Invariant Stochastic Jitter Monitor 

   Kim, Yong-Jo; Jang, Taekwang; Cho, SeongHwan (2024)

   IEEE Journal of Solid-State Circuits

   We propose a digital bang-bang phase locked-loop (DBPLL) whose output rms jitter can be set to a user-defined value. By using a stochastic jitter monitoring circuit (JMC) and automatic loop bandwidth control, the proposed BBPLL can adjust its power consumption to obtain the desired target jitter during its initial set-up, regardless of conditions in process, voltage, and temperature (PVT). Implemented in 28 nm CMOS, the prototype PLL ...

3. Gendered choices of labour market integration programmes: evidence from the United States 

   Morle, Guillaume; Caves, Katherine (2024)

   Evidence-Based HRM

   PurposeWe investigate whether women are more likely than men to choose to pursue a competency-based labour market integration programme, rather than the time-based labour market integration programme. We further investigate whether women with existing but uncertified skills are even more likely to pursue a competency-based labour market integration programme.Design/methodology/approachWe test our hypotheses using ordinary least squares ...

4. The fireball of November 24, 1970, as the most probable source of the Ischgl meteorite 

   Gritsevich, Maria; Moilanen, Jarmo; Visuri, Jaakko; et al. (2024)

   Meteoritics & Planetary Science

   The discovery of the Ischgl meteorite unfolded in a captivating manner. In June 1976, a pristine meteorite stone weighing approximately 1 kg, fully covered with a fresh black fusion crust, was collected on a mountain road in the high-altitude Alpine environment. The recovery took place while clearing the remnants of a snow avalanche, 2 km northwest of the town of Ischgl in Austria. Subsequent to its retrieval, the specimen remained tucked ...

5. Siracusa: A 16 nm Heterogenous RISC-V SoC for Extended Reality With At-MRAM Neural Engine 

   Prasad, Arpan Suravi; Scherer, Moritz; Conti, Francesco; et al. (2024)

   IEEE Journal of Solid-State Circuits

   Extended reality (XR) applications are machine learning (ML)-intensive, featuring deep neural networks (DNNs) with millions of weights, tightly latency-bound (10-20 ms end-to-end), and power-constrained (low tens of mW average power). While ML performance and efficiency can be achieved by introducing neural engines within low-power systems-on-chip (SoCs), system-level power for nontrivial DNNs depends strongly on the energy of non-volatile ...
