Hmn-384 -

The analog neuron arrays exploit hafnium‑oxide (HfO₂) memristors fabricated in a 22 nm fully‑depleted silicon‑on‑insulator (FD‑SOI) process. Memristors provide non‑volatile weight storage, eliminating the need for periodic refresh cycles and enabling instant power‑on boot. The digital spine of each tile resides in standard high‑performance logic gates, leveraging existing CMOS IP blocks for the NoC and DSE.

A noteworthy material innovation is the cross‑point thermal isolation trench, which prevents local heating of the analog cross‑bars from propagating across the mesh. This design permits aggressive voltage scaling without risking thermal runaway—a common obstacle in dense analog neuromorphic arrays.

The HMN‑384 incorporates multi‑level voltage scaling and event‑driven power gating:

Combined, these mechanisms enable sub‑watt operation for inference on moderately sized models (e.g., a ResNet‑18 analog equivalent consumes ≈ 0.8 W at 30 fps on a 1080p video stream). HMN-384

The modular nature of HMN‑384 invites straightforward scaling to HMN‑1024 or larger meshes for data‑center inference, where latency is less critical but raw throughput matters. Future iterations may interconnect multiple meshes via high‑speed silicon‑photonic links, forming a hyper‑neural fabric spanning entire server racks.

Tight coupling of spiking sensors (event cameras, silicon photomultipliers) with the HMN‑384 eliminates the need for analog‑digital conversion stages, creating a sensor‑processor monolith that could redefine perception pipelines in robotics and biology.

The discovery of HMN-384 represents a significant advancement in the field of targeted kinase inhibitors. While CDK11 has long been implicated in cancer progression, the lack of selective inhibitors has prevented the validation of this target in the clinic. Our data demonstrates that HMN-384 achieves high target specificity by exploiting subtle differences in the ATP-binding pocket of CDK11 compared to other transcriptional CDKs like CDK9.

The mechanism of action of HMN-384 is distinct from current standards of care. By inhibiting CDK11, HMN-384 disrupts the transcription-splicing axis, a vulnerability particularly pronounced in the "transcriptionally addicted" TNBC subtype. The induction of intron retention suggests that cancer cells cannot tolerate the loss of CDK11-mediated RNA processing, leading to apoptotic cell death. This mechanism provides a rationale for the use of HMN-384 in tumors that have developed resistance to CDK4/6 inhibitors via Rb loss or Cyclin E amplification.

Crucially, the safety profile of HMN-384 in preclinical models addresses a major bottleneck in CDK inhibitor development. The dissociation of efficacy from hematological toxicity suggests that HMN-384 can be dosed effectively in humans to achieve therapeutic coverage without the severe neutropenia that limits the use of broad-spectrum CDK inhibitors.
