Abstract

This paper firstly introduces our shared Matlab source code that simulates the two optimal-ordered SIC detectors proposed in [1] and [2]. Based on our shared Matlab code, we compare the computational complexities between the two detectors in [1] and [2] by theoretical complexity calculations and numerical experiments. We carry out theoretical complexity calculations to obtain the worst-case complexities for the two detectors in [1] and [2]. Then from the theoretical worst-case complexities, we make the conclusion that the detector proposed in [2] requires 9N 2 more floating-point operations (flops) than the detector proposed in [1], where N is the number of transmit antennas. Our numerical experiments also show that the detector in [2] requires more worst-case and average complexities than the detector in [1].

Subspace Learning with Interval-Censored Likelihoods for Dequantizing Percept PC LFP Snapshots

Implanted neurostimulators that sense local field potentials now enable chronic electrophysiology based biomarker tracking in patients at home. The Medtronic Percept PC, the only commercially available sensing-enabled deep brain stimulation (DBS) device, stores spectral amplitudes as 16-bit integers at approximately 0.1 $μ$V per bit (quantum $q \approx 0.11$ $μ$Vp). At frequencies where the true amplitude spans only a few quantization levels, consecutive bins round to the same stored value. Standard spectral parameterization (FOOOF, fitting oscillations and one over f), which separates periodic peaks from the aperiodic 1/f activity, treats every value as exact and fits oscillatory peaks to these plateaus. Because these spectra feed clinical biomarker pipelines and spectral foundation models for symptom decoding, spurious peaks can corrupt downstream inference. Across 9,438 spectra from 14 hemispheres in 7 subcallosal cingulate DBS patients, 20.6% of peaks detected at [2, 45] Hz have no match in ground truth synthesized by quantizing clean in-clinic BrainSense recordings, while aggregate beta band power and the aperiodic exponent are preserved. We formalize dequantization as interval-censored subspace estimation and compare five classes of correction methods. Quantized probabilistic PCA is the only tested method that reduces the spurious rate (20.6% to 18.3%) while preserving true peak detection and keeping noise floor RMSE below $q/\sqrt{12}$.

TiamiTwin: A Digital Twin for Bistatic ISAC Drone Sensing, Validated Against Measurements

Monitoring lower airspace over critical infrastructure using cellular signals of opportunity is highly practical because transmitters are pre-deployed, licensed, and continuously active. Digital twins can evaluate the feasibility of such integrated sensing and communication (ISAC) architectures, but their predictive accuracy must be validated against real-world data. This paper reports validation results for TiamiTwin, a digital twin developed for bistatic ISAC drone sensing, using empirical measurements from an operational 5G deployment featuring a commercial band n41 gNB and a receiver separated by 572.8 m over a non-line-of-sight (NLOS) channel. TiamiTwin incorporates three parallel channel representations evaluated on a 240-subcarrier grid: the 3GPP TR 38.901 (Release 19) bistatic ISAC model, a ray-traced site model, and the captured field measurements. Empirical results demonstrate that both statistical and ray-tracing models under-predict the measured root-mean-square (RMS) delay spread by approximately a factor of three. Furthermore, target reflections sit 68 dB below static clutter in power, making target detection entirely dependent on Doppler separation to isolate the drone from zero-Doppler background returns. Despite this severe clutter environment, the target remains separable along 88% of the flight path in the delay, Doppler, or joint delay-Doppler domains.

Extracting Physiological Numeric Values from French Pediatric ICU Notes: A Multi-Objective Representation Learning Approach

Numeric values in clinical narratives, such as heart rate, oxygen saturation, and pressure gradients, carry diagnostic meaning that Transformer models trained on generic text do not capture. Objective: We categorize numerical values in French pediatric intensive care unit (PICU) notes into eight physiological categories using CamemBERT-bio, under two constraints that make large-scale LLMs impractical: only 1,072 real, annotated clinical samples are available for this rare, single-site condition, and training must run on GPUs shared concurrently with other hospital workloads rather than a dedicated cluster. Methods: We compare fine-tuning CamemBERT-bio with Label Embedding for Self-Attention (LESA) against combining LESA with Xval, a magnitude-aware number embedding, under a multi-objective training loss. Results: Standard fine-tuning did not improve F1 score, but CamemBERT-bio + LESA raised it by over 13%, and adding Xval matched this gain while approaching GPT-4's performance. Conclusion: LESA and Xval let a compact encoder achieve reliable physiological value extraction under limited real data and shared hospital compute, offering a practical alternative to large-scale LLMs. Significance: Under limited-data and shared-compute constraints, this compact BERT-based language model remains effective without the resource trade-offs of trillion-parameter LLMs.
