Compactification for essentially finite-type maps

open access: yesAdvances in Mathematics, 2009
We show that any separated essentially finite-type map $f$ of noetherian schemes globally factors as $f = hi$ where $i$ is an injective localization map and $h$ a separated finite-type map. In particular, via Nagata's compactification theorem, $h$ can be chosen to be proper. We apply these results to Grothendieck duality.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Gps Essential For Mapping Species Distribution

open access: yes, 2018
Conservation of our environment is the important phenomenon which includes integration of government, scientist and local community to understand the fauna or flora present in a particular region. This is where the role citizen science comes to play. In addition to the community technological collaboration will results in scientific conclusion for any ...

Essential dimension lowering mappings having dense deficiency set [PDF]

open access: yesTransactions of the American Mathematical Society, 1985
A map \(f: X\to Y\) is said to be one-to-one over the image of \(D\subset X\) provided the restriction of f yields a homeomorphism from \(f^{- 1}(f(D))\to f(D)\). It is perhaps startling to find maps that are one-to- one over the image of a dense subset that represent any element of \(\pi_ n(S^ n)\) for \(n\geq 3\), the only obvious one being the ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Elementary examples of essential phantom mappings

open access: yesRad Hrvatske akademije znanosti i umjetnosti. Razred za matematičke, fizičke i kemijske znanosti. Matematičke znanosti, 2015
It is known that essential phantom mappings (of the second kind) between connected CW-complexes do exist. However, it appears that in the literature there are few explicit examples of such mappings. One usually finds descriptions of the domain and the codomain and an existence proof that the set of homotopy classes of mappings from the domain to the ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A Method of Cartographic Visualization for Climate Change Maps

open access: yesKartografija i Geoinformacije, 2011
Maps are essential in climate change research. This paper considers examples of cartographic visualizations for different climate change characteristics. International map symbol systems used in climate change maps are analyzed.

On essential singularities of meromorphic mappings

open access: yesMathematische Annalen, 1989
The three notions ``essential singularity of the i-th kind, \(i=1,2,3''\) of a meromorphic mapping are introduced: A meromorphic mapping \(f: X\to Y\), where \(X^ *\), Y are normal complex spaces and \(X\subset X^ *\) is an open subset, is said to have an essential singularity of the i-th kind in a point P lying on the border of X if f doesn't admit ...
