Mean values with cubic characters

, 2010
We investigate various mean value problems involving order 3 primitive Dirichlet characters. In particular, we obtain an asymptotic formula for the first moment of central values of the Dirichlet L-functions associated to this family, with a power saving

A Bound for a Sum of Products of Two Characters and Its Application

, 2023
Using the exponent pair method, a bound is derived for the sum ∑manb≤xχ1a(m)χ2b(n), where a,b are fixed positive integers, χ1,χ2 are primitive Dirichlet characters modulo q1 and q2, respectively, and χ1a,χ2b are not ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

Advanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

LORD OF THE FLIES: A NARRATIVE OF HUMAN ESSENCE AND THE DICTATORSHIP AGE

Zeitschrift für die Welt der Türken, 2016
Lord of the Flies is an anti-utopic (dystopic) novel by the English author William Golding, who wrote about how human’s primitive aspect can peep out by portraying kids whose ages vary from 5 to 12 on a deserted island.

Genomic insights into the origin and evolution of spelt (Triticum spelta L.) as a valuable gene pool for modern wheat breeding

Plant Communications
Spelt (Triticum aestivum ssp. spelta) is an important wheat subspecies mainly cultivated in Europe before the 20th century that has contributed to modern wheat breeding as a valuable genetic resource. However, relatively little is known about the origins

New Lower Cretaceous basal mantodean (Insecta) from the Crato Formation (NE Brazil)

Geologica Carpathica, 2014
Mantodea are very rare in the fossil record. 28 fossil species are reported since the earliest occurrence of mantodeans in the Upper Jurassic (Tithonian). Here, I describe Cretophotina santanensis n. sp. from the Aptian (Lower Cretaceous) Crato Formation

Primitive Characters and Permutation Characters of Solvable Groups

, 2007
Let X be an irreducible, primitive complex character of the finite solvable group G, and let X* denote the complex conjugate character. If the degree X(1) is odd, then we show how to associate to X in a unique way, a conjugacy class of subgroups U of G for which X*X = (1_U)^G, the permutation character on the cosets of U.
