Raw moss layer projective cover at 32 sites in Northwester Canada, in Summer 2022 (CA-Land_2022_NWCanada)

open access: yes, 2023
Vegetation surveys were carried out in Northwest Territories, Yukon and British Columbia in Canada. The study area is within the boreal forest biome and is partially underlain by permafrost soils. The aim was to record the projective ground vegetation in

Epimorphisms and maximal covers in categories of compact spaces

open access: yesApplied General Topology, 2013
The category C is "projective complete"if each object has a projective cover (which is then a maximal cover). This property inherits from C to an epireflective full subcategory R provided the epimorphisms in R are also epi in C. When this condition fails,

Ramified cover of varieties with nef cotangent bundle

open access: yesComptes Rendus. Mathématique, 2022
We construct examples to show that having nef cotangent bundle is not preserved under finite ramified covers. Our examples also show that a projective manifold with Stein universal cover may not have nef cotangent bundle, disproving a conjecture of Liu ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Impact of weed infestation on projective soil cover changes during the sunflower vegetation period

open access: yesЛюдина і довкілля: Проблеми неоекології
Weed infestation is one of the key factors influencing the formation of plant cover in agroecosystems. In the context of sunflower cultivation, projective soil cover varies depending on the intensity of weed competition, especially during critical ...

The Impact of the COVID‐19 Pandemic on Childhood Cancer Survival: A Population‐Based Assessment of Survival Patterns Between 2015 and 2023 in Germany

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Numerous international studies have reported declines in new cancer diagnoses, delayed diagnoses and disruptions in cancer treatment following the implementation of COVID‐19 pandemic public health measures, raising concerns that these effects may ultimately contribute to increased cancer mortality.

Semi-perfect and F-semi-perfect modules

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
A module is semi-perfect iff every factor module has a projective cover. A module M=A+B (for submodules A and B) is amply supplemented iff there exists a submodule A′ (called a supplement of A) of B such M=A+A′ and A′ is minimal with this property.
