RETRACTED ARTICLE: Extremal surface with the light-like line in Minkowski space R1+(1+1) $R^{1+(1+1)}$

Boundary Value Problems, 2017
In this paper, firstly we will give the global construction of the mixed type extremal surface in Minkowski space along the analytic light-like line. Furthermore, we construct simply the local existence of extremal surface along a single light-like line.

EXTREMAL DEPENDENCE IN EXCHANGE RATE MARKETS [PDF]

Exchange rate markets exhibit correlation in the short run, but the issue is whether such correlation lingers over long periods of time, and under extreme events (i.e., either large appreciations or depreciations).

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

Molecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

An extremal problem for univalent functions [PDF]

Let S be the class of functions f(z)=z+a2z2 ,… f(0)=0, f′(0)=1 which are regular and univalent in the unit disk |z| x the equation φ′( x)=0 does not have real roots. Since S is a compact class, there exists x . This problem was first proposed by Petru T.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Generalised Harrison transformations and black diholes in Einstein-ModMax

Journal of High Energy Physics
Einstein-Maxwell theory has powerful solution generating techniques which include Harrison transformations in the Ernst formalism. We construct generalised Harrison transformations that preserve the purely magnetic or purely electric sector in Einstein ...

On the universal method to solve extremal problems [PDF]

Some applications of the theory of extremal problems to mathematics and economics are made more accessible to non-experts.1.The following fundamental results are known to all users of mathematical techniques, such as economist, econometricians, engineers

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Gaussian Tests of "Extremal White Noise" for Dependent, Heterogeneous, Heavy Tailed Strochastic Processes with an Application [PDF]

We develop a non-parametric test of tail-specific extremal serial dependence for possibly heavy-tailed time series. The test statistic is asymptotically chi-squared under a null of "extremal white noise", as long as extremes of the time series are Near ...

Extremal elements in Lie Algebras [PDF]

, 2014
The main result discussed in this lecture is an elementary proof of the following theorem: If L is a simple Lie algebra over F of characteristic distinct from 2 and 3 having an extremal element that is not a sandwich, then either F has characteristic 5 ...
