Zooplankton diel vertical migration enhances carbon export via distinct mechanisms in a warming North Pacific

Limnology and Oceanography Letters
Zooplankton diel vertical migration (DVM) is a crucial marine organism behavior modulating particulate organic carbon (POC) export, yet its dynamic role under climate change remains uncertain.

Dynamics and Model Predictive Control of Current-Fed Dickson Voltage Multiplier: TS Fuzzy Approach

IEEE Access, 2022
This study presents a new approach to modeling and control the current-fed Dickson voltage multiplier (CF-DVM). The capacitor voltage relation and the input current are obtained.

Diel vertical migration in deep sea plankton is finely tuned to latitudinal and seasonal day length. [PDF]

PLoS ONE, 2013
Diel vertical migration (DVM) is a ubiquitous phenomenon in marine and freshwater plankton communities. Most commonly, plankton migrate to surface waters at dusk and return to deeper waters at dawn.

Caracterización probabilística de las fechas de ocurrencia de las crecientes anuales mediante la distribución de von Mises

Tecnología y ciencias del agua, 2023
La planeación y manejo de los recursos hidráulicos de un río y la elaboración de los planes ―de tipo no estructural― de mitigación de daños causados por sus inundaciones dependen de la relación que guarda el gasto máximo anual con su fecha de ocurrencia.

An evaluation of multi-species empirical tree mortality algorithms for dynamic vegetation modelling

Scientific Reports, 2021
Tree mortality is key for projecting forest dynamics, but difficult to portray in dynamic vegetation models (DVMs). Empirical mortality algorithms (MAs) are often considered promising, but little is known about DVM robustness when employing MAs of ...

European guidelines from the EHTG and ESCP for Lynch syndrome: an updated third edition of the Mallorca guidelines based on gene and gender

BJS (British Journal of Surgery), EarlyView., 2020
Recommendations for clinical and molecular identification of LS, surgical and endoscopic management of LS‐associated colorectal cancer and preventive measures for cancer were produced. The emphasis was on surgical and gastroenterological aspects of the cancer spectrum.

Efficient and Self-Recursive Delay Vandermonde Algorithm for Multi-Beam Antenna Arrays

IEEE Open Journal of Signal Processing, 2020
This paper presents a self-contained factorization for the delay Vandermonde matrix (DVM), which is the super class of the discrete Fourier transform, using sparse and companion matrices. An efficient DVM algorithm is proposed to reduce the complexity of

Contrasting two major Arctic coastal polynyas: the role of sea ice in driving diel vertical migrations of zooplankton in the Laptev and Beaufort seas [PDF]

Ocean Science
The diel vertical migration (DVM) of zooplankton is one of the largest species migrations to occur globally and is a key driver of regional ecosystems and the marine carbon pump. Previously thought to be hampered by the extreme light regime prevailing in
