DIFFERENTIAL FORMS ON DIFFERENTIAL SPACES

open access: yesDemonstratio Mathematica, 1994
Die Autoren definieren die wesentlichen Begriffe, um eine Analysis auf Differentialräumen \((M,C)\) zu konstruieren: \(k\)-Vektoren, Differentialformen, äußere Ableitung und Integration. Dabei gehen sie nicht vom üblichen Begriff des Tangentialvektors als Derivation auf \(C\) aus, sondern definieren ``glatte Halbkurven'' als glatte Abbildungen \([0,1[ \

Differentiable projections and differentiable semigroups [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
Suppose X is a Banach space, G is a connected open subset of X, and p is a continuously Fr6chet differentiable function from G into G satisfying p(p(x))=p(x) for each x in G. We prove that p(G) is a differentiable submanifold of X and use this result to show that the maximal subgroup containing an idempotent in a differentiable semigroup is a Lie group.

Optimisation of growth conditions for ovine airway epithelial cell differentiation at an air-liquid interface [PDF]

open access: yes, 2018
Respiratory tract infections are of significant concern in the agriculture industry. There is a requirement for the development of well-characterised in vitro epithelial cell culture models in order to dissect the diverse molecular interactions occurring

Hadamard differentiability via Gâteaux differentiability [PDF]

open access: yesProceedings of the American Mathematical Society, 2014
Let $X$ be a separable Banach space, $Y$ a Banach space and $f: X \to Y$ a mapping. We prove that there exists a $ $-directionally porous set $A\subset X$ such that if $x\in X \setminus A$, $f$ is Lipschitz at $x$, and $f$ is G teaux differentiable at $x$, then $f$ is Hadamard differentiable at $x$.

Hepatocyte Differentiation [PDF]

open access: yes, 2010
Increasingly, research suggests that for certain systems, animal models are insufficient for human toxicology testing. The development of robust, in vitro models of human toxicity is required to decrease our dependence on potentially misleading in vivo animal studies.

The C/EBPβ LIP isoform rescues loss of C/EBPβ function in the mouse

open access: yesScientific Reports, 2018
The transcription factor C/EBPβ regulates hematopoiesis, bone, liver, fat, and skin homeostasis, and female reproduction. C/EBPβ protein expression from its single transcript occurs by alternative in-frame translation initiation at consecutive start ...

NuMA regulates mitotic spindle assembly, structural dynamics and function via phase separation

open access: yesNature Communications, 2021
Mitotic spindle assembly is required for proper cell division, but many underlying mechanisms remain unclear. Here, the authors show that NuMa undergoes liquid-liquid phase separation, condensing on spindle poles during mitotic entry and enriching ...

MicroRNAs regulate T-cell production of interleukin-9 and identify hypoxia-inducible factor-2a as an important regulator of T helper 9 and regularoty T-cell differentiation [PDF]

open access: yes, 2016
MicroRNAs (miRNAs) regulate many aspects of helper T cell (Th) development and function. Here we found that they are required for the suppression of interleukin‐9 (IL‐9) expression in Th9 cells and other Th subsets. Two highly related miRNAs (miR‐15b and

Diversity, Stability, Recursivity, and Rule Generation in Biological System: Intra-inter Dynamics Approach

open access: yes, 1998
Basic problems for the construction of a scenario for the Life are discussed. To study the problems in terms of dynamical systems theory, a scheme of intra-inter dynamics is presented.
