Alkalinity responses to climate warming destabilise the Earth’s thermostat

open access: yesNature Communications, 2023
The weathering alkalinity flux from mid-latitudes to the ocean will be strongly altered by climate warming by 2100. Under different emissions scenarios either a strengthening or a weakening of the flux and thus of the oceanic CO2 buffer is predicted.

A multi-site study of the relationship between photoperiod and ovulation rate using Natural Cycles data

open access: yesScientific Reports, 2023
Many species exhibit seasonal patterns of breeding. Although humans can shield themselves from many season-related stressors, they appear to exhibit seasonal patterns of investment in reproductive function nonetheless, with levels of sex steroid hormones

LIFE CYCLE OF PRODUCTS AND CYCLES [PDF]

open access: yesMacroeconomic Dynamics, 2010
The aim of this paper is to examine whether the development of waste recycling activities can be a source of economic fluctuations. We assume that the recycling sector has four fundamental characteristics. (i) The production factors are restricted by the production of the last period.

Analysis of Control-System Strategy and Design of a Small Modular Reactor with Different Working Fluids for Electricity and Hydrogen Production as Part of a Decentralised Mini Grid

open access: yesEnergies, 2022
Hydrogen is increasingly being viewed as a significant fuel for future industrial processes as it offers pathways to zero emission. The UK sees hydrogen as one of a handful of low-carbon solutions for transition to net zero.

SOLAR CYCLE 25: ANOTHER MODERATE CYCLE? [PDF]

open access: yesThe Astrophysical Journal Letters, 2016
ABSTRACT Surface flux transport simulations for the descending phase of Cycle 24 using random sources (emerging bipolar magnetic regions) with empirically determined scatter of their properties provide a prediction of the axial dipole moment during the upcoming activity minimum together with a realistic uncertainty range. The expectation

Enumeration of cyclic vertices and components over the congruence a¹¹ ≡ b (mod n) [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
For each positive integer n, we assign a digraph Γ(n,11) whose set of vertices is Zₙ={0,1,2,...,n-1} and there exists exactly one directed edge from the vertex a to the vertex b iff a¹¹ ≡ b (mod n).

Impacts of additional cycles of neoadjuvant immunotherapy on surgery in non‐small‐cell lung cancer

open access: yesThoracic Cancer, 2023
Objective Whether cycle number influences the subsequent pathological or surgical outcomes remained unclear. This study aimed to assess the efficacy and surgical safety of neoadjuvant immunochemotherapy‐based treatment in the real‐world setting.

Hypothesis and Theory: A Two-Process Model of Torpor-Arousal Regulation in Hibernators

open access: yesFrontiers in Physiology, 2022
Hibernating mammals drastically lower their metabolic rate (MR) and body temperature (Tb) for up to several weeks, but regularly rewarm and stay euthermic for brief periods.
