Using single and double laser pulses on the molecular Ni@CH system to design integrated nanospintronic units.

The accomplishment of long-distance spin transfer scenarios between several magnetic centers is a big challenge for building and supporting spin-logic units for developing future all-optical magnetic unit operations. Using high-level quantum chemistry theory CCSD and EOM-CCSD, we systematically study the ultrafast laser-induced spin-dynamics process on a carbon-based material, to which four magnetic centers are attached. We show that the CCSD method with the 6-31G basis set calculation is sensitive to the C-Ni bond length.

Laser-induced ultrafast spin-transfer processes in non-linear zigzag carbon chain systems.

We combine the high-level quantum chemistry theory CCSD and EOM-CCSD together with local and global Λ processes to investigate the details of the laser-induced ultrafast spin manipulation scenarios in non-linear zigzag carbon chain systems Ni@CH and Ni@CH. The spin density distribution, which is calculated on each many-body state using a Mulliken population analysis, fulfills the requirements to accomplish the spin dynamics processes. Various spin-flip and spin-transfer scenarios are accomplished.

Ultrafast control of laser-induced spin-dynamics scenarios on two-dimensional Ni3@C63H54 magnetic system.

The concept of building logically functional networks employing spintronics or magnetic heterostructures is becoming more and more popular today. Incorporating logical segments into a circuit needs physical bonds between the magnetic molecules or clusters involved. In this framework, we systematically study ultrafast laser-induced spin-manipulation scenarios on a closed system of three carbon chains to which three Ni atoms are attached.

Genetic Diversity and Population Structure of in Morocco as Revealed by Multilocus Sequence Typing (MLST) Approach.

is endemic in Morocco, and it causes both visceral (VL) and cutaneous leishmaniasis (CL). In this study, the multilocus sequence typing (MLST) approach was used to investigate the phylogeny and population structure of strains isolated from CL and VL patients and the canine reservoir in different leishmaniasis endemic foci in Morocco. For this purpose, eight loci (, , , , , , and ) were amplified in 40 samples, out of which 31 were successfully sequenced.

Anxiety and Depression Symptoms in At-Risk Pregnancy: Influence on Maternal-Fetal Attachment in Tunisia.

Objectives: To investigate maternal prenatal anxiety and depression in high-risk pregnancies and examine their influence on maternal-fetal attachment.

Methods: We included 95 hospitalized high-risk pregnant women. The Hospital Anxiety and Depression Scale (HADS) and the Prenatal Attachment Inventory (PAI) were used to assess the primary objective.
