This article presents a new algorithm used in order to convert the speech of one speaker so that it sounds like that of another speaker. This algorithm flexibly converts voice quality using two major technical developments. Firstly, the modification of formant frequencies and spectral intensity using piecewise linear voice conversion rules. This enables the control of spectrum parameters in det...

A subset C of an abelian group G is said to be a minimal additive complement W⊆G if C+W=G and C′+W≠G for any proper C′⊂C. In this paper, we study certain subsets the integers that arise or do not as complements. Following suggestion Kwon, show bounded-below sets with arbitrarily large gaps Moreover, our construction shows such set belongs co-minimal pair, strengthening result Biswas Saha lacuna...

This paper presents an ultra-low-standby-power radio transmitter that was designed for applications with extreme energy storage and/or energy harvesting constraints. By utilizing aggressive power gating techniques within a low-complexity architecture featuring only a single RF stage, the transmitter achieved a standby power consumption of 39.7 pW. The architecture employed a direct-RF power osc...

The control and manipulation of light on the nanoscale — the primary aim of nanophotonics — is of fundamental scientific interest and plays a key role in telecommunication technologies and energy management. Yet, because light–matter interactions are usually weak and hard to confine, they often need to be assisted by the use of suitably designed macroscopic media. For instance, the use of caref...

Many of the classical results of Ramsey Theory are naturally stated in terms of image partition regularity of matrices. Many characterizations are known of image partition regularity over N and other subsemigroups of (R,+). We study several notions of image partition regularity near zero for both finite and infinite matrices, and establish relationships which must hold among these notions.

Let $G=(V,E)$ be a simple graph. A set $Ssubseteq V$ isindependent set of $G$,  if no two vertices of $S$ are adjacent.The  independence number $alpha(G)$ is the size of a maximumindependent set in the graph. In this paper we study and characterize the independent sets ofthe zero-divisor graph $Gamma(R)$ and ideal-based zero-divisor graph $Gamma_I(R)$of a commutative ring $R$.

Helium has always been a bit of an outsider on the Periodic Table. Its two isotopes, helium-3 and helium-4, remain liquid down to absolute zero and have the lowest liquefaction temperature among the gases. These features can be traced to the high zero-point energy relative to their attractive potential. In two dimensions, helium4 will form a liquid and become superfluid at temperatures that dep...
