A 2021 CDC report on 378,048 US deaths attributed to COVID-19 identified a co-occurring diagnosis of chain-of-event condition (COE) (e.g., pneumonia, respiratory failure), or significant contributing (SCC) diabetes, dementia), both; in 91.9% the patients. This study assessed prevalence comorbid COE and/or SCC among diagnosed patients large open-source claims database. Patients with any claim in...

In this paper, a property of Schur polynomial of real coe cients and real Toeplitz matrix is given. Suppose that the vector of real coe cients of a Schur polynomial annihilates a real Toeplitz matrix, then the Toeplitz matrix is in fact a zero matrix.

Convergence of stochastic processes with jumps to di!usion processes is investigated in the case when the limit process has discontinuous coe$cients. An example is given in which the diffusion approximation of a queueing model yields a di!usion process with discontinuous di!usion and drift coe$cients. c © 2002 Elsevier Science B.V.

"In this paper, we obtain certain generalizations of some results from [13] and [14]. Let $\Phi_{n, \alpha, \beta}$ be the extension operator introduced in \cite{GrahamHamadaKohrSuffridge} let Q}$ [7]. $a \in \C$, $b \R$ such that $|1-a| < b \leq {\rm Re}\ a$. We consider Janowski classes $S^*(a,b, \B)$ $\A S^*(a,b, with complex coefficients [16]. In case $n=1$, denote \mathbb{B}^1)$ by $S^*...

madam, cardamom, often referred to as queen of spices because of its very pleasant aroma and taste, has a history as old as human race. it is especially common in the indian subcontinent and is known for its delicious aroma, aphrodisiac properties and also as a common folk remedy to treat stomach aches.[1] both in middle east and india, it is used for flavoring hot beverages such as tea and cof...

The cuticle of terrestrial plants functions as a protective barrier against many biotic and abiotic stresses. In wheat and other Triticeae, β-diketone waxes are major components of the epicuticular layer leading to the bluish-white glaucous trait in reproductive-age plants. Glaucousness in durum wheat is controlled by a metabolic gene cluster at the WAX1 (W1) locus and a dominant suppressor INH...

the knowledge about climatic comfort plays an important role in the humans life and her activities. in fact many human activates are directly related with climatic comfort in every region. this paper analyzed the climatic comfort in province kurdistan (sanandaj, saghez, bijar, ghorve, zarine, marivan and bane meteorological stations). rates of climatic comfort analyzed in meteorological station...

We give a formula for the coe‰cients of the Yablonskii-Vorob’ev polynomial. Also the reduction modulo a prime number of the polynomial is studied.
