Conditional emotions

Philosophical Perspectives, Volume 37, Issue 1, Page 145-163, December 2023., 2023
Abstract Some conditional involving factive emotives present a prima facie challenge to the thesis that conditionals obey modus ponens. Drawing on recent work by Timothy Williamson, I offer an error‐theoretic diagnosis of the phenomenon, one that appeals to a heuristic that we use in suppositional reasoning.

Leaf surface features of maize cultivars and response to foliar phosphorus application: effect of leaf stage and plant phosphorus status

Physiologia Plantarum, Volume 175, Issue 6, November/December 2023., 2023
Abstract Soil phosphorus (P) application is the most common fertilisation technique but may involve constraints due to chemical fixation and microbial immobilisation. Furthermore, excessive P fertilisation leads to P runoff into water bodies, threatening ecosystems, so targeted foliar P fertilisation is an interesting alternative.

Evasiveness and the Distribution of Prime Numbers [PDF]

, 2010
We confirm the eventual evasiveness of several classes of monotone graph properties under widely accepted number theoretic hypotheses. In particular we show that Chowla's conjecture on Dirichlet primes implies that (a) for any graph $H$, "forbidden ...

Fractal in the statistics of Goldbach partition

, 2006
Some interesting chaos phenomena have been found in the difference of prime numbers. Here we discuss a theme about the sum of two prime numbers, Goldbach conjecture. This conjecture states that any even number could be expressed as the sum of two prime numbers.

Achieving quantum advantage in a search for a violations of the Goldbach conjecture, with driven atoms in tailored potentials

SciPost Physics Core
The famous Goldbach conjecture states that any even natural number $N$ greater than $2$ can be written as the sum of two prime numbers $p^{\text{(I)}}$ and $p^{\text{(II)}}$.

Divisor Goldbach Conjecture and its Partition Number

, 2016
Based on the Goldbach conjecture and arithmetic fundamental theorem, the Goldbach conjecture was extended to more general situations, i.e., any positive integer can be written as summation of some specific prime numbers, which depends on the divisible factor of this integer, that is: For any positive integer $n~(n>2)$, if there exists an integer $m$,

Effects of temporal and spatial variability in energy fluxes on phytoplankton

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Climate change has significantly altered the energy dynamics of lakes; however, little is known of how the temporal and spatial variation in energy fluxes impacts the structure and function of lake ecosystems. This study combined long‐term (2011–2018) measurements of lake energy fluxes with environmental, nutrient, and phytoplankton data at ...

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Uganda

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the likelihood of pest freedom at entry in the EU, including both regulated and non‐regulated pests, potentially associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Uganda.

Every sufficiently large even number is the sum of two primes [PDF]

, 2019
The binary Goldbach conjecture asserts that every even integer greater than $4$ is the sum of two primes. In this paper, we prove that there exists an integer $K_\alpha$ such that every even integer $x > p_k^2$ can be expressed as the sum of two primes ...

Thirty-two Goldbach Variations

, 2005
We give thirty-two diverse proofs of a small mathematical gem--the fundamental Euler sum identity zeta(2,1)=zeta(3) =8zeta(\bar 2,1). We also discuss various generalizations for multiple harmonic (Euler) sums and some of their many connections, thereby ...
