A Robust Method for Pitch Tracking in the Frequency Following Response using Harmonic Amplitude Summation Filterbank
The Frequency Following Response (FFR) reflects the brain's neural encoding of auditory stimuli including speech. Because the fundamental frequency (F0), a physical correlate of pitch, is one of the essential features of speech, there has been particular interest in characterizing the FFR at F0, especially when F0 varies over time. The standard method for extracting F0 in FFRs has been the Autocorrelation Function (ACF). This paper investigates harmonic-structure-based F0 estimation algorithms,…

Stability of soluble surfactant-laden falling film over a hydrophobic incline in the presence of external shear
The hydrodynamic stability analysis of gravity-driven, soluble surfactant-laden fluid streaming down a slippery, slanted plane in the presence of external shear force is being explored in this article. The Navier-Stokes equations are considered for the fluid flow along with the appropriate advection-diffusion equations for the concentration of different surfactant species. The monomers considered here are anticipated to dissolve in the bulk flow and can be adsorbed at the interface of air-liqui…

ZK-SERIES: Privacy-Preserving Authentication using Temporal Biometric Data
Biometric authentication relies on physiological or behavioral traits that are inherent to a user, making them difficult to lose, forge or forget. Biometric data with a temporal component enable the following authentication protocol: recent readings of the underlying biometrics are encoded as time series and compared to a set of base readings. If the distance between the new readings and the base readings falls within an acceptable threshold, then the user is successfully authenticated. Various…

Senate Democrats are increasingly concerned that President Donald Trump is considering striking Iran without seeking authorization from Congress
— or even filling them in on his plans.

Sen. Tim Kaine (D-Virginia) is mounting a last-ditch push to force a vote as soon as next week
to restrain Trump from attacking Iran without Congress’s approval.

Other Senate Democrats say the White House has not briefed them on its plans for a potential strike.
And some are warn…

Democrats raise war powers concerns as Trump mulls Iran strike
The pushback follows Trump’s encroachment on almost every congressional prerogative — from taking control of the power of the purse to threatening tariffs.

On the Vertices of Delta-modular Polyhedra
Let $P$ be a polytope defined by the system $A x \leq b$, where $A \in R^{m \times n}$, $b \in R^m$, and $\text{rank}(A) = n$. We give a short geometric proof of the following tight upper bound on the number of vertices of $P$: $$ n! \cdot \fracΔ{Δ_{\text{average}}} \cdot \text{vol}(B_2) \sim \frac{1}{\sqrt{πn}} \cdot \left(\frac{2 π}{e}\right)^{n/2} \cdot n^{n/2} \cdot \fracΔ{Δ_{\text{average}}}, $$ where $Δ$ is the maximum absolute value of $n \times n$ subdeterminants of $A$, and $�…

Optimal Control of Thin-Film Flow on a Flexible Topography
This work presents a mathematical model for the optimal control of thin-film flows over a flexible topography influenced by an external force. Our thin-film model allows for the rupture of films as well as the coalescence of bubbles. The objective is to find the optimal distributed force acting on the topography that minimises the differences between actual and desired thin-film profiles. A nonlinear lubrication equation governing the fluid dynamics and appropriate functional settings for this …

Cred raises fresh funds from GIC, others; valuation cut by 45% to $3.5 billion
The fintech major was valued at $6.4 billion in 2022 during its last major fund infusion. The current fund infusion is in the form of primary capital, which means that existing investors have not sold any shares in this round. The drop in valuation was in line with the company's plans to list in India over the next two years, people in the know said.
