Looking backward: From Euler to Riemann
We survey the main ideas in the early history of the subjects on which Riemann worked and that led to some of his most important discoveries. The subjects discussed include the theory of functions of a complex variable, elliptic and Abelian integrals ...

ABSTRACT Reconstructing (pre‐)historic land use distribution is essential for understanding past human societies and their impacts on the environment. Various land use forms result in distinct alterations of surface morphology, which are often well preserved but rarely described within forest areas. The interpretation of LiDAR Digital Elevation Models (

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Costa Rica
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica.

Small‐scale distribution of linear patterns of primes
Abstract Let Ψ=(ψ1,⋯,ψt):`Zd→Rt$\Psi =(\psi _1,\hdots, \psi _t):`\mathbb {Z}^d\rightarrow \mathbb {R}^t$ be a system of linear forms with finite complexity. In their seminal paper, Green and Tao showed the following prime number theorem for values of the system Ψ$\Psi$: ∑x∈[−N,N]d∏i=1t1P(ψi(x))∼(2N)d(logN)t∏pβp,$$\begin{equation*} \sum _{x\in [-N,N]^d}

Abstract Frying is a popular cooking method that produces delicious and crispy foods but can also lead to oil degradation and the formation of health‐detrimental compounds in the dishes. Chemical reactions such as oxidation, hydrolysis, and polymerization contribute to these changes.

Sifting Function Partition for the Goldbach Problem
All sieve methods for the Goldbach problem sift out all the composite numbers; even though, strictly speaking, it is not necessary to do so and which is, in general, very difficult. Some new methods introduced in this paper show that the Goldbach problem can be solved under sifting out only some composite numbers.

Implications of Ramsey Choice principles in ZF$\mathsf {ZF}$
Abstract The Ramsey Choice principle for families of n$n$‐element sets, denoted RCn$\operatorname{RC}_{n}$, states that every infinite set X$X$ has an infinite subset Y⊆X$Y\subseteq X$ with a choice function on [Y]n:={z⊆Y:|z|=n}$[Y]^n:= \lbrace z\subseteq Y: |z| = n\rbrace$.

Summary In this review, we untangle the physiological key functions of the essential micronutrients and link them to the deficiency responses in plants. Knowledge of these responses at the mechanistic level, and the resulting deficiency symptoms, have improved over the last decade and it appears timely to review recent insights for each of them.

Understanding the role of boron in plant adaptation to soil salinity
Abstract Soil salinity is a major environmental constraint affecting the sustainability and profitability of agricultural production systems. Salinity stress tolerance has been present in wild crop relatives but then lost, or significantly weakened, during their domestication. Given the genetic and physiological complexity of salinity tolerance traits,

Proposta di Dimostrazione della variante Riemann di Lagarias (RH1) equivalente all’Ipotesi di Riemann RH, con RH1 = RH. [PDF]
Scopo del presente lavoro è quello di proporre una dimostrazione dell'Ipotesi di Riemann attraverso quella che tecnicamente viene definita "variante di Lagarias".
