Many real world processes can be represented as compositions of functions along a directed acyclic graph (DAG). In causal modelling, these correspond to the underlying mechanisms; in engineering, to multiple fidelity levels; and in gene regulatory networks, to transcription factors. These functions are partially observed across the DAG, with noisy and heterogeneously sampled measurements, posing significant challe...
Controlling the energy scales of a quantum system is essential for defining robust qubits. In silicon spin qubits, the nearly degenerate conduction band valleys create a leakage channel from the single spin computational basis, posing a challenge to scaling and to shuttling based architectures. Here, we measure the relevant energy scales of single electron spin qubits in buried silicon quantum wells co designed fo...
In this work, we present B spline Policy (BSP), an action representation designed for accelerating robot manipulation policies. Rather than predicting discrete time action chunks, BSP parameterizes actions as continuous B spline curves defined by a set of knots and control points. This representation yields smooth, time continuous trajectories that can be temporally scaled and executed by low level controllers at ...
Achieving valley splittings well in excess of the thermal energy of electrons and avoiding valley excitations is essential for the consistent initialization, operation and readout of gate defined Si spin qubits. In this work, we present a device level optimization strategy for pushing valley splittings to between 1 and 5 meV, well beyond values reported in nearly all previous theoretical studies. Using device scal...
This dataset comprises EEG recordings from 25 healthy participants performing motor imagery and spatial attention tasks across five sessions. The study investigates the integration of simultaneous motor imagery and overt spatial attention (MIOSA) for brain computer interface control, with participants performing left hand and right hand imagery tasks while receiving visual cursor feedback. Data were acquired using...
Reliable autonomous driving requires full scene perception that couples foreground objects with dense semantic layout. Recently, 4D millimeter wave radar has emerged as a robust and affordable sensor, yet its sparse returns make radar camera fusion necessary for comprehensive scene understanding. Existing radar camera methods mainly optimize detection, while dual task systems usually decode boxes and occupancy wit...
A P300 based brain computer interface dataset for home appliance control, comprising EEG recordings from 14 healthy subjects performing a visual oddball task with 31 channel recordings at 500 Hz sampling rate. The dataset includes 50 training and 30 testing trials per subject, with binary target and non target stimulus classifications presented via LCD display in an online BCI paradigm.
A 40 class steady state visually evoked potential (SSVEP) brain computer interface dataset designed to reduce visual fatigue through beta range frequency stimulation (14.0–21.8 Hz). The dataset comprises 33 channel EEG recordings from 40 healthy participants performing a speller task across 6 sessions, with stimuli presented using the joint frequency phase modulation (JFPM) approach. This resource supports the dev...
Pre demolition assessment, the regulated audit process at the heart of urban mining, is an information process in which AI support must serve qualified auditors who remain accountable for the decisions taken. The relevant unit of value is not prediction accuracy alone, but the defensibility of the supported decisions: their legibility, plausibility, sourcing, and contestability. Explainable AI techniques and domai...
We present an interpretable network based framework for representing idiomatic and figurative meaning across eight typologically diverse languages, totaling 160 conventional expressions, the large majority of which are idiomatic. Each expression is annotated with binary conceptual features (containment, concealment, emotional, social, etc.) derived from cognitive linguistic theory, and pairwise Jaccard similaritie...
Extending and refining a preceding work, the free evolution of a quantum wave function, with fixed initial and final modulus, is considered in the general case where nodes are allowed. The method is based on considering a suitable simple functional related to the quadratic optimal transport cost in discrete time. Under reasonable assumptions it is shown that, if nodes are present, the free evolution of the wave fu...
A P300 brain computer interface EEG dataset comprising recordings from 19 healthy participants across 3 sessions. The study investigates the effects of visual stimulation conditions (standard flash versus cartoon face stimuli) on P300 BCI performance using an 8 channel montage sampled at 256 Hz, with data collected using a P300 paradigm across 5 grid sizes and including target and non target event classifications....
This dataset comprises EEG recordings from 84 healthy participants performing motor imagery tasks across multiple controlled environments (laboratory and simulated hospital), with a supplementary cohort of 3 participants recorded in microgravity conditions in a space station environment. The dataset includes multiple motor imagery paradigms (Graz, SSMVEP MI, and hybrid variants) with 64 channel EEG recordings at 1...
We present a hybrid halo model, which improves the description of the 2 halo term by incorporating non linear information from simulations. A linear computation of the halo halo power spectrum is inaccurate at the transition between the 1 halo and 2 halo regimes, whereas nonlinear approaches such as Hybrid Effective Field Theory (HEFT) are not naturally compatible with the halo model decomposition. We address this...
This dataset contains electroencephalogram (EEG) recordings from 19 healthy participants using a brain computer music interface designed to enable real time control of musical tempo through motor imagery. Participants performed kinesthetic motor imagery tasks—imagining squeezing a ball to increase tempo or relaxing to decrease tempo—across nine experimental runs including a calibration phase. The data were collect...
This dataset comprises EEG recordings from 12 healthy participants performing upper limb motor imagery tasks centered on elbow movements. Participants executed kinesthetic imagery of nine goal directed tasks (drawer opening, soup preparation, weight lifting, door opening, plate cleaning, combing, pizza cutting, and pick and place operations) plus rest, cued by visual stimuli. The dataset contains 330 trials record...
We report the confirmation and characterisation of two moderate period sub Jovian planets transiting the bright F type star HD 148797 (G=9.4 mag, Teff=6441 +/ 51 K). Using photometric time series from TESS and CHEOPS, we determine orbital periods of 42.1 d for HD 148797 b and 68.2 d for HD 148797 c, putting the period ratio very close to the golden mean at 1.619 and therefore near several strong harmonics, and mea...
BCIComp2020UpperLimb is a preprocessed EEG dataset from BCI Competition 2020 Track 4 containing motor imagery recordings of three upper limb grasping tasks (cylindrical, spherical, lumbrical) from 15 healthy subjects across three sessions. The dataset comprises 60 channel EEG data sampled at 250 Hz with 450 trials per subject (150 trials per session × 3 sessions), designed to evaluate session to session transfer l...
Partial differential equations are a promising application area for fault tolerant quantum algorithms, but the subject lies between two communities with different languages: numerical analysis and quantum computation. These lecture notes provide a numerically grounded introduction for readers entering from either field. Block encoding is the organizing principle: once a discretized differential operator is embedde...
We expand on the ideas developed by C. Jarzynski in Physica A 552, 122077 (2020), where an integral fluctuation theorem was derived with the aim of obtaining thermodynamic inequalities stronger than those implied by the Jarzynski equality. Restricting ourselves to the quantum setting, we derive the corresponding detailed fluctuation theorem and additional detailed and integral fluctuation theorems; we also provide...
