HOW THIS WORKS ↗PUBLICATION INDEX
CHANNEL // 01 [15]
Research into artificial intelligence and intelligent systems.
Randomly nudging a language model’s output scores can rival perturbing its weights on reasoning tasks, a study finds. The results challenge the idea that such gains require a hidden thicket of task-specific experts near the original model.
SpecSlot gives image regions separate tokens for broad structure and fine detail, routing only the structure-bearing tokens globally. Its authors report competitive image-generation quality with lower compute than selected Transformer controls.
A luggage-matching study found that combining selected frames from airport video tracks improved top-ranked identification over choosing a random frame. Camera coverage and training data from the target environment also mattered, although missed detections and mismatches remained.
CHANNEL // 02 [15]
Research into plants, their biology, and their environments.
T-SWITCH records Agrobacterium DNA delivery separately from integration in Arabidopsis: about 13–26% of delivery events lacked detectable integration. It also enabled recovery of edited plants without detectable CRISPR components.
Across generations of Arabidopsis, the loss of DNA-demethylating enzymes allowed new methylation marks to accumulate in different places in different lineages. The plants also developed divergent gene-expression profiles, suggesting that active mark removal helps keep inherited epigenetic states stable.
Highbush blueberry flower primordia stay ice-free in fall and winter even as surrounding bud tissue freezes. Researchers located the apparent barrier near each developing flower and found that its seasonal loss coincided with maturation of the tiny xylem strands connecting the flowers to the stem.
CHANNEL // 03 [15]
Research into economic systems, decisions, and policy.
A model of household solar and battery choices finds that electricity rates can make the technologies either reinforce or displace each other. In a Massachusetts-based simulation, that interaction also changed how much of the utility’s cost of serving customers was recovered.
Taihei Oki and Ryosuke Sato propose an ascending-price algorithm for trading networks where fees, taxes and subsidies make buyers’ payments differ from sellers’ receipts. Under specified assumptions, they show that it reaches the lowest competitive-equilibrium price for every trade and can recover an equilibrium allocation.
A study of policy decisions under statistical uncertainty finds that treating estimated effects as exact can produce dangerously large actions. A dampened rule offers a compromise between aggressive intervention and maintaining the status quo.
