- ALICE (A Large Ion Collider Experiment) is the LHC (Large Hadron Collider) experiment devoted to investigating the strongly interacting matter created in nucleus-nucleus collisions at the LHC energies. The ALICE ITS, Inner Tracking System, consists of six cylindrical layers of silicon detectors with three different technologies; in the outward direction: two layers of pixel detectors, two layers each of drift, and strip detectors. The number of parameters to be determined in the spatial alignment of the 2198 sensor modules of the ITS is about 13,000. The target alignment precision is well below 10 mu m in some cases (pixels). The sources of alignment information include survey measurements, and the reconstructed tracks from cosmic rays and from proton-proton collisions. The main track-based alignment method uses the Millepede global approach. An iterative local method was developed and used as well. We present the results obtained for the ITS alignment using about 10(5) charged tracks from cosmic rays that have been collected during summer 2008, with the ALICE solenoidal magnet switched off.

- The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those processes, because they are shielded from the s-process flow and r-process beta-decay chains. These nuclei are attributed to the p and rp process. For all those processes, current research in nuclear astrophysics addresses the need for more precise reaction data involving radioactive isotopes. Depending on the particular reaction, direct or inverse kinematics, forward or time-reversed direction are investigated to determine or at least to constrain the desired reaction cross sections. The Facility for Antiproton and Ion Research (FAIR) will offer unique, unprecedented opportunities to investigate many of the important reactions. The high yield of radioactive isotopes, even far away from the valley of stability, allows the investigation of isotopes involved in processes as exotic as the r or rp processes.

The large enriched germanium experiment for neutrinoless double beta decay (LEGEND)

- The observation of neutrinoless double-beta decay (0νββ) would show that lepton number is violated, reveal that neu-trinos are Majorana particles, and provide information on neutrino mass. A discovery-capable experiment covering the inverted ordering region, with effective Majorana neutrino masses of 15 - 50 meV, will require a tonne-scale experiment with excellent energy resolution and extremely low backgrounds, at the level of ∼0.1 count /(FWHM·t·yr) in the region of the signal. The current generation 76Ge experiments GERDA and the Majorana Demonstrator, utilizing high purity Germanium detectors with an intrinsic energy resolution of 0.12%, have achieved the lowest backgrounds by over an order of magnitude in the 0νββ signal region of all 0νββ experiments. Building on this success, the LEGEND collaboration has been formed to pursue a tonne-scale 76Ge experiment. The collaboration aims to develop a phased 0νββ experimental program with discovery potential at a half-life approaching or at 1028 years, using existing resources as appropriate to expedite physics results.

beta -Delayed gamma -Ray Spectroscopy of Heavy Neutron Rich Nuclei "South" of Lead
- 2009

Konferensbidrag (refereegranskat)abstract
- Relativistic projectile fragmentation of a Pb-208 primary beam has been used to produce neutron-rich nuclei with proton-holes relative to the Z = 82 shell closure, i.e., "south" of Pb. beta-delayed gamma-ray spectroscopy allows to investigate the structural properties of such nuclei with A similar to 195 -> 205. The current work presents transitions de-exciting excited states in Au-204, which are the first spectroscopic information on this N = 125 isotone.

Analysis and Results of the 104Sn Coulomb Excitation Experiment
- 2014

- The analysis of the Coulomb excitation experiment conducted on 104Sn required a strict selection of the data in order to reduce the large background present in the gamma-ray energy spectra and identify the gamma-ray peak corresponding to the Coulomb excitation events. As a result the B(E2; 0 + -> 2+) value could be extracted, which established the downward trend towards 100Sn and therefore the robustness of the N=Z=50 core against quadrupole excitations.

- In the current era genetic sequencing has emerged as an indispensable methodology for examining diverse DNA profiles across domains encompassing healthcare, agriculture, and forensic science. To enhance precision, a range of techniques, including high-throughput shotgun sequencing, have evolved over time. Recent strides in next-generation sequencing methodologies have facilitated the embedding of data within DNA using synthesized oligonucleotides. Notably, significant efforts have been dedicated to embedding extensive volumes of information within living organisms to safeguard intellectual property. When it comes to DNA steganography, traditional detection methods, exemplified by frequency analysis-based approaches, often overlook crucial signals and are susceptible to newly emerging steganography techniques. This study undertakes a comprehensive analysis of inherent allocations, distribution variance computation, and the classification of sequences as coding or non-coding. Our research endeavors to devise an advanced security strategy employing DNA steganography. Central to our proposition is the utilization of DNA steganography to forge a robust security framework. In this study, we introduce the DNA-Genetic Encryption (D-GET) mechanism to augment security. The D-GET technique involves the binarization of digital data followed by its conversion into DNA sequences. Subsequently, a sequence of operations, including reshaping, encryption, crossover, and mutation, is performed iteratively to heighten the robustness and unpredictability of the technique. The core processes of D-GET are iterated at least three times. Encrypted data is transmitted in either text or image file formats. Upon reception, the D-GET approach is employed to decode and restore the acquired data to its original form. A distinguishing aspect of our approach is the transformation of textual content into visual representations and vice versa, augmenting security measures. Multiple key sequences are leveraged to amplify the degree of dispersion and ambiguity, rendering the final cipher data highly intricate to decipher. Empirical observations highlight that our proposed methodology affords multi-layered security attributes, fortified by multi-stage and genetic operations, rendering it resilient against diverse threats and affording an elevated level of safeguarding. Notably, the methodology's efficacy derives from the pronounced divergence between the transformed information and the confidential content, thereby reinforcing the integrity of the encryption framework.
