On partial approximate controllability of semilinear systems

open access: yesCogent Engineering, 2014
In this paper, a sufficient condition for the partial approximate controllability of semilinear deterministic control systems is proved. Generally, the theorems on controllability are formulated for control systems given as a first-order differential ...

Vortex of a Regional Security Complex: The EuroMed Partnership and its Security Relevance. EUMA Papers, Vol. 5, No. 11 May 2008 [PDF]

open access: yes, 2008
[From the introduction]. Studying the Mediterranean as a geo-political region, Pace (2003, 161) states that “the study of regions must in some way include the study of meaning and identity”.

Precipitation changes in the Mediterranean basin during the Holocene from terrestrial and marine pollen records: a model–data comparison [PDF]

open access: yes, 2017
Climate evolution of the Mediterranean region during the Holocene exhibits strong spatial and temporal variability. The spatial differentiation and temporal variability, as evident from different climate proxy datasets, has remained notoriously difficult

Evaluating the (comparative) safety profile of the novel oral polio vaccine type 2 using individual case safety reports in VigiBase

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Novel oral polio vaccine type 2 (nOPV2) was used under the WHO emergency use listing for circulating vaccine‐derived polio virus (cVDPV) outbreaks from 2021 to 2023. We assessed nOPV2 adverse events following immunization (AEFIs) and compared its safety profile to other vaccines using VigiBase.

Saharan dust deposition may affect phytoplankton growth in the mediterranean sea at ecological time scales [PDF]

open access: yes, 2014
The surface waters of the Mediterranean Sea are extremely poor in the nutrients necessary for plankton growth. At the same time, the Mediterranean Sea borders with the largest and most active desert areas in the world and the atmosphere over the basin is

Mid‐Domain Effect and Wooded Habitat Shape Mediterranean Reptile Communities

open access: yesBiological Diversity, EarlyView.
Analyzing a large number of reptiles observed across protected areas in Central Italy, we tested whether the mid‐domain effect explains hump‐shaped richness–elevation patterns. Species richness was best predicted by the combined influence of geometric constraints and woodland cover, revealing two contrasting species clusters and offering a robust ...

Public self-reported familiarity with thyroid disorders in Northern Cyprus

open access: yesDiscover Public Health
Background The thyroid gland plays a fundamental role in regulating the body's metabolism through the secretion of thyroxine (T4) and triiodothyronine (T3), under the control of thyroid-stimulating hormone (TSH) produced by the pituitary gland ...

Relationship between flexural toughness energy and impact energy of high strength fiber reinforced concrete (HSFRC)

open access: yesMateriales de Construccion, 2001
A simple, economical and practical impact resistance test method has been developed for high strength fiber reinforced concrete (HSFRC). The results indicated that there is a logarithmic relation between flexural toughness energy (EFT) and impact energy (

Trophic relationships of zooplankton in the eastern Mediterranean based on stable isotope measurements [PDF]

open access: yes, 2009
Abundance and stable isotope composition of large and small mesozooplankton were analyzed in samples taken with 333 and 100 μm nets, respectively, at four sites in the eastern Mediterranean down to 4200 m depth in October 2001. Large mesozooplankton (333

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
