DEEP NEURAL NETWORK-BASED APPROACH FOR COMPUTING SINGULAR VALUES OF MATRICES

Science Journal of University of Zakho
Matrix factorization techniques, such as Singular Value Decomposition (SVD), Eigenvalue Decomposition (EVD), and QR decomposition, have long been pivotal in computational mathematics, particularly for applications in signal processing, machine learning,

The Effects of Monetary Policy in the United Kingdom: New Evidence From SONIA Market Responses

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper constructs a new measure of the UK monetary policy instrument (MPI) using daily changes in the sterling overnight index average (SONIA) around Bank of England policy events from June 1997 to August 2025. The instrument explicitly accounts for pre‐event information and unconventional monetary policy (UMP) using lagged macro‐financial

Identifying Peer Effects in Networks with Unobserved Effort and Isolated Students

Journal of Applied Econometrics, EarlyView.
ABSTRACT Peer influence on effort devoted to some activity is often studied when effort is unobserved, and the researcher instead observes an outcome that combines effort with other shocks. For instance, in education, achievement measures such as GPA reflect both effort and idiosyncratic GPA shocks.

A Tale of Two Transitions: Mobility Dynamics in China and Russia After Central Planning

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper examines intergenerational mobility in China and Russia during their transitions from central planning to market systems. We consider mobility as movement, measured as changes in status between parents and children. We provide estimates of two key mobility measures: overall mobility, which captures total intergenerational movement ...

Recovering steady‐state visual evoked potential‐related electroencephalography during amplitude‐modulated‐transcranial alternating current stimulation using dynamic adaptive stimulation artifact source separation

Journal of Intelligent Medicine, EarlyView.
Abstract Simultaneous electroencephalography (EEG) recording during transcranial alternating current stimulation (tACS) is strongly contaminated by stimulation artifacts, limiting direct assessment of neural activity. Steady‐state visual evoked potentials (SSVEPs) provide frequency‐specific and phase‐locked responses, making them suitable for ...

Event-B model decomposition

, 2009
Two methods have been identified in the DEPLOY project for Event-B model decomposition: the shared variable decomposition (called A-style decomposition), and the shared event decomposition (or B-style decomposition).

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Effective cooperative scheme based on relay selection

Tongxin xuebao, 2010
Based on the capacity of multi-access channel,a relay selection algorithm was proposed.It was proposed that: relays were selected according to the eigenvalue decomposition of the equivalent relay-destination channel,and the beamforming vectors were ...

A talus rock glacier in Nantlle Valley, North Wales

Journal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...
