Mass splittings of nuclear isotopes in chiral soliton approach

open access: yes, 2004
The differences of the masses of nuclear isotopes with atomic numbers between \~10 and ~30 can be described within the chiral soliton approach in satisfactory agreement with data.

Tuning (Anti)Aromaticity: Variations on the [8]‐Circulene Framework

open access: yesChemPhysChem, Volume 25, Issue 7, April 2, 2024.
Depending on substitution pattern and charge, this single versatile π framework (tetracyclopenta[def,jkl,pqr,vwx] tetraphenylene (TCPTP)) can host any combination of aromaticity and antiaromaticity, as judged from tropicity of currents, ranging from concentric global circulations of both senses to localised eddies, all with an intuitive orbital ...

Sub‐Micron Thickness Self‐Limiting Electrospray Deposition via Voltage Bias of Spray Target

open access: yesAdvanced Materials Interfaces, Volume 11, Issue 12, April 24, 2024.
Sub‐micron coating thickness via electrospray deposition is achieved through implementing a voltage bias onto the target. By doing so, the charged droplets are deterred from depositing onto the target, thus decreasing the coating thickness. This technique also has the potential to reintroduce self‐limiting behavior, thus being useful for applications ...

Pan‐Cancer Single‐Nucleus Total RNA Sequencing Using snHH‐Seq

open access: yesAdvanced Science, Volume 11, Issue 5, February 2, 2024.
In this study, snHH‐seq, a high‐throughput, and high‐sensitivity snRNA‐seq method, is applied to pan‐cancer samples from 32 patients, comprising > 700 000 nuclei from various cancer types. The comprehensive analysis of gene expression, somatic mutations, splicing patterns, and clonal behavior shows broad implications for understanding tumor pathology ...

Quasi-Deuteron Configurations in odd-odd N=Z nuclei [PDF]

open access: yes, 1999
The isovector M1 transitions between low-lying T=1 and T=0 states in odd-odd N=Z nuclei are analyzed. Simple analytical expressions for M1 transition strengths are derived within a single-j-shell approximation for both j=l+1/2 and j=l-1/2 cases.

Rydberg states of helium in electric and magnetic fields of arbitrary relative orientation

open access: yes, 2016
A spectroscopic study of Rydberg states of helium ($n$ = 30 and 45) in magnetic, electric and combined magnetic and electric fields with arbitrary relative orientations of the field vectors is presented. The emphasis is on two special cases where (i) the

A Tractable Line-of-Sight Product Channel Model: Application to Wireless Powered Communications [PDF]

open access: yes, 2018
We here present a general and tractable fading model for line-of-sight (LOS) scenarios, which is based on the product of two independent and non-identically distributed κ- μ shadowed random variables.

XMM-Newton Observations of Radio Pulsars B0834+06 and B0826-34 and Implications for Pulsar Inner Accelerator

open access: yes, 2008
We report the X-ray observations of two radio pulsars with drifting subpulses: B0834 + 06 and B0826 - 34 using \xmm\. PSR B0834 + 06 was detected with a total of 70 counts from the three EPIC instruments over 50 ks exposure time.

A Minimum Principle in Codon-Anticodon Interaction

open access: yes, 2011
Imposing a minimum principle in the framework of the so called crystal basis model of the genetic code, we determine the structure of the minimum set of anticodons which allows the translational-transcription for animal mitochondrial code.
