Accurately distinguishing between peripheral and menstrual bloodstains at crime scenes is a major challenge in forensic practice. The time since deposition (TSD) of the scene also plays an essential role determining postmortem interval or injury time. In this study, we used attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy combined with chemometric methods to differentiate considering TSD phase.The results principal component analysis (PCA) model showed that...
We study the Heisenberg antiferromagnet with single-ion anisotropy in two and three dimensions present self-consistent intuitive theory to show Bose-Einstein condensation-induced long-range order gapped magnetic systems, when energy gap is tuned zero by changing physical parameters or applying an external field. The recent experimental results on ${\mathrm{NiCl}}_{2}∙4\mathrm{SC}{({\mathrm{NH}}_{2})}_{2}$ are interpreted theory. Many other systems share same picture. also helpful...
Abstract High‐entropy alloys (HEAs) have garnered extensive attention owing to their broad compositional tunability and high catalytic activity. However, precisely modulating the enzyme‐like activity of HEAs enhancing biocompatibility for biological applications remain severely challenging. Herein, PtRuFeCoNi HEA nanowires (NWs) are synthesized by adjusting metal composition surface‐engineered with polydopamine (PDA) form NWs@PDA nanozymes (HEzymes@PDA) superior photothermal properties....
This study evaluated the role of physical and biological filter characteristics on reduction MS2 bacteriophage in biosand filters (BSFs). Three full-scale concrete Version 10 BSFs, each with a 55 cm sand media depth 12 L charge volume, reached 4 log10 within 43 days operation. A consistently high between 7 was demonstrated for up to 294 days. Further examining one revealed that an average 2.8 achieved first 5 filter, cumulative virus 5.6 after 240 Core samples from this were taken protein,...

The bond operator representation of quantum $S=\frac{1}{2}$ spins with the singlet state being projected out is applied to investigate isotropic spin-1 Heisenberg antiferromagnetic chain $H={\ensuremath{\sum}}_{i}[{\mathbf{S}}_{i}\ensuremath{\cdot}{\mathbf{S}}_{i+1}\ensuremath{-}\ensuremath{\beta}({\mathbf{S}}_{i}\ensuremath{\cdot}{\mathbf{S}}_{i+1}{)}^{2}]$. In approximation Bose condensation, ground-state properties system and their $\ensuremath{\beta}$ dependences are studied. results at...

A bond operator representation of quantum $S=1$ spins is developed along the same line to $S=\frac{1}{2}$ spins. The two representations are then applied investigate magnetization isotropic spin-$1$ antiferromagnetic chains and spin-$\frac{1}{2}$ spin ladders. With appropriate states projected out, ladders can be mapped effective Hamiltonians $\mathcal{S}=\frac{1}{2}$ pseudospins in external magnetic fields. features analyzed with use existing rigorous results $\mathrm{XXZ}$ chains.

International service learning (ISL) programs seek to facilitate community inclusion, but such participation can prove elusive. For technical projects, ventures undermine local leadership, generate mistrust in communities, and even create an aversion technological solutions. In this article, we document how social work engineering students collaborated bring clean water rural Guatemala, demonstrate employed principles address the myriad issues encountered project. We contend that inclusion...
The bilayer spin-$1/2$ antiferromagnetic Heisenberg model is studied by the bond-operator mean-field theory and perturbation theory. From both methods, zero-temperature quantum phase transition occurs at a critical ratio of ${(J}_{2}{/J}_{1}{)}_{c}\ensuremath{\approx}2.3,$ where ${J}_{1}$ ${J}_{2}$ are intralayer interlayer coupling constants. Under method, obtained spin-wave mass, uniform susceptibility, inverse correlation length point show good linear behavior versus temperature low...

A bond operator representation for three $S=\frac{1}{2}$ spins is obtained along the same line as two-spin cases. With spin and chirality freedom expressed by operators, we studied elementary excitations of spin-tube spin-orbit models. For $3$-leg ladders general with an odd number legs periodic boundary conditions in rung direction, spinonlike excitations, which carry $\frac{1}{2}$ freedoms, are calculated a variational ansatz. The magnonlike denote change dimerized from singlet to triplet...
