In this paper, we are dealing with the study of locating chromatic number Möbius-ladders. We prove that Möbius-ladders Mn n even has 4 if n≠6 and 6 n=6.

A gap exists in understanding organizational career ladders for IT professionals. This gap is especially pronounced in organizations externally sourcing IT related activities to vendors, given that technical positions often feed the pipeline to mid-level roles. Based on prior research and qualitative discussions with key informants, this paper discusses the skills necessary for mid-level roles ...

– We have measured the temperatureand frequency dependence of the microwave and millimeter wave conductivity σ1(T, ω) along both the ladder (c-axis) and the leg (a-axis) directions in Sr14Cu24O41. Below a temperature T ∗(∼170 K), we observed a stronger frequency dependence in σc 1(T, ω) than that in σ a 1 (T, ω), forming a small resonance peak developed between 30 GHz and 100 GHz. We also obser...

In the present paper, we propose a mean field approach for spin ladders based upon the Jordan-Wigner transformation along an elaborately ordered path. We show on the mean field level that ladders with even number legs open a energy gap in their low energy excitation with a magnitude close to the corresponding experimental values, whereas the low energy excitation of the odd-number-leg ladders a...

We report on the syntheses and characterizations of single crystalline and polycrystalline Sr2Co3S2O3 with a novel crystal structure type. It contains Co-O 2-leg rectangular ladders and necklace ladders. The two ladders share common legs and construct a hybrid spin ladder. A rare meridional heteroleptic octahedral coordination is found for the Co2+ ions in the 2-leg ladder. Within the necklace ...

Sets of RNA ladders can be synthesized by transcription of a bacteriophage-encoded RNA polymerase using 3'-deoxynucleotides as chain terminators. These ladders can be used for sequencing of DNA. Using a nicked form of phage SP6 RNA polymerase in this study substantially enhanced yields of transcriptional sequencing ladders. Matrix-assisted laser desorption/ionization time-of-flight mass spectro...

Abstract: The paper presents a new calibration algorithm for current output R-2R ladders. The R-2R ladders are popular because they are easy to realise, but the resistance tolerances limit their linearity properties. However, it is possible to achieve higher linearity with self-calibration techniques. A formerly published algorithm by Cutkosky is available for the so-called Cutkosky R-2R ladder...

One way of making the transition between the quasi-long range order in a chain of S=1/2 spins coupled antiferromagnetically and the true long range order that occurs in a plane, is by assembling chains to make ladders of increasing width. Surprisingly this crossover between one and two dimensions is not at all smooth. Ladders with an even number of legs have purely short range magnetic order an...
