<abstract><p>In this work, we investigate the differential geometric characteristics of pedal and primitive curves in a Minkowski plane. A is specified by opposite structure for creating pedal, primitivoids are known as comparatives plane curve. We inspect relevance between pedals that relate with symmetry properties. Furthermore, under viewpoint symmetry, expand these notions to frontal Then, present relationships properties category. Numerical examples presented here support our main results.</p></abstract>

The present paper is focused on time-like circular surfaces and singularities in Minkowski 3-space. timelike surface with a constant radius could be swept out by moving Lorentzian circle its center while following non-lightlike curve called the spine curve. In study, we have parameterized examined their geometric properties, such as striction curves, corresponding those of ruled surfaces. After that, different kind was determined named roller coaster surface. Meanwhile, support results this work some examples.

In this paper, we give the parametric equation of Bishop frame for a timelike sweeping surface with unit speed curve in Minkowski 3-space. We introduce new geometric invariant to explain properties and local singularities surface. derive sufficient necessary conditions be developable ruled Afterwards, take advantage singularity theory classification Furthermore, some representative examples show applications theoretical results.

DeoxyriboNucleic Acid (DNA) encryption is a new method that appeared along with the research of DNA nanotechnology in recent years. Due to complexity biology nanotechnology, brings an additional difficulty deciphering and, thus, can enhance information security. As approach strand displacement has particular advantages such as being enzyme free and self-assembly. However, existing on DNA-strand-displacement-based mostly stayed at theoretical or simulation stage. To this end, paper proposes framework. This framework involves three main strategies. The first strategy was tri-phase conversion from plaintext sequences according Huffman-coding-based transformation rule, which enhances concealment information. second development molecular modules, produce initial key for encryption. third cyclic-shift-based operation extend long enough, thus increase difficulty. results biological experiments demonstrated feasibility our scheme further validated terms sensitivity, space, statistic characteristic. Our provides potential way realize via promotes

Abstract Due to the high heterogeneity of cancers, it is rather essential explore driver modules with help gene mutation data as well known interactions between genes/proteins. Unfortunately, latent false positive are inevitable in Protein-Protein Interaction (PPI) network. Hence presented method, a new weight evaluation index, based on gene-microRNA network somatic profile, introduced for weighting PPI first. Subsequently, vertices weighted hierarchically clustered by measuring Mahalanobis distance their feature vectors, extracted graph embedding method Node2vec. Finally, heuristic process dropping and extracting conducted clusters produce group modules. Numerous experiment results demonstrate that proposed exhibits superior performance four cutting-edge identification methods most cases regarding capability recognizing acknowledged cancer-related genes, generating having relatively coverage mutual exclusivity, significantly enriched specific types cancers. The majority genes identified involved signaling pathways, or have been reported be carcinogenic literature. Furthermore, many cancer related detected actually omitted comparison methods, which has verified experiments.

When collecting experimental data, the observable may be dichotomous. Sampling (eventually with replacement) thus emulates a Bernoulli trial leading to binomial proportion. Because distribution is discrete, analytical evaluation of exact confidence interval sampled outcome mathematical challenge. This paper proposes three alternative calculation methods that are characterized and exemplified.

In this article, a Ricci soliton and *-conformal are examined in the framework of trans-Sasakian three-manifold. beginning paper, it is shown that three-dimensional manifold type (α,β) admits where covariant derivative potential vector field V direction unit ξ orthogonal to ξ. It also demonstrated if structure functions meet α2=β2, then constant multiple Furthermore, nature scalar curvature evolved when satisfies soliton, provided α≠0. Finally, an example presented verify findings.

The approach of the study is on singularity properties timelike circular surfaces in Minkowski 3-space. A surface a one-parameter set Lorentzian circles with stationary radius directing non-null space curve, which acts as spine and it has symmetrical properties. In this study, we addressed gained their geometric such Gaussian mean curvatures, comparable those ruled surfaces. Consequently, presented roller coaster special class Then, conditions for to be flat or minimal are obtained. Meanwhile, supported results some examples.

Often in the planning phase of a clinical trial, researcher will need to choose between standard versus weighted log-rank test (LRT) for investigating right-censored survival data. While LRT is optimal analyzing evenly distributed but distinct events (proportional hazards), an appropriately may be better suited handling non-proportional, delayed treatment effects. The “a priori” misspecification this alternative result substantial loss power when determining effectiveness experimental drug. In paper, unweighted and inverse tests (iLRTs) are compared with multiple weight, default Max-Combo procedure differential late outcomes. Unlike combination LRTs that depend on arbitrary selection weights, iLRT by definition single weight does not require implicit multiplicity correction. Empirically, both methods have reasonable flexibility assessing continuous curve differences from onset study. However, preferable accommodating separating curves, especially one arm finishes first. Using large-sample methods, sample size easily estimated without resorting complex timely simulations.
