description: The energy-momentum tensor, which is coordinate independent, is used to calculate energy, momentum and angular-momentum of two different tetrad fields. Although, the two tetrad fields reproduce the same space-time their energies are different. Therefore, a regularized expression of the gravitational energy-momentum tensor of the teleparallel equivalent of general relativity, (TEGR), is used to make the energies of the two tetrad fields equal. The definition of the gravitational energy-momentum is used to investigate the energy within the external event horizon. The components of angular-momentum associated with these space-times are calculated. In spite that we use a static space-times, we get a non-zero component of angular-momentum! Therefore, we derive the killing vectors associated with these space-times using the definition of the Lie derivative of a second rank tensor in the framework of the TEGR to make the picture more clear.

description: Peter Mansfield's rise from humble origins to founding father of magnetic resonance imaging (MRI) is an inspirational and remarkable story. His first scientific contributions were in the field of solid state nuclear magnetic resonance (NMR), and it was whilst trying to develop an NMR version of X-ray crystallography that he developed the underpinning methodology for MRI. At that time (the early 1970s) NMR was an analytical tool, ubiquitous in chemistry departments. For most of those working in the field, there was no hint that it could be developed into a diagnostic imaging technique that would reveal internal anatomy in unprecedented detail. Yet that was what happened in the space of just a few years. The first MRI scans were slow, and Peter was driven to speed them up, making physiological and later functional brain imaging studies possible. The technical challenges were many, and eschewed by healthcare equipment providers, but Peter persisted and his brainchild, echo-planar imaging, came to dominate the high speed MRI field. Peter was a gifted physicist and archetypal inventor who devoted his life to the development of a technique that has saved millions of lives. In 2003, he shared the Nobel Prize for Physiology or Medicine, in recognition of his achievement.

description: We study the interface representation of the contact process (CP) at its directed-percolation critical point, where the scaling properties of the interface can be related to those of the original particle model. Interestingly, such a behavior happens to be intrinsically anomalous and more complex than that described by the standard Family-Vicsek dynamic scaling Ansatz of surface kinetic roughening. We expand on a previous numerical study by Dickman and Muñoz [Phys. Rev. E 62, 7632 (2000)] to fully characterize the kinetic roughening universality class for interface dimensions $d=1, 2$, and 3. Beyond obtaining scaling exponent values, we characterize the interface fluctuations via their probability density function (PDF) and covariance, seen to display universal properties which are qualitatively similar to those recently assessed for the Kardar-Parisi-Zhang (KPZ) and other important universality classes of kinetic roughening. Quantitatively, while for $d=1$ the interface covariance seems to be well described by the KPZ, Airy$_1$ covariance, no such agreement occurs in terms of the fluctuation PDF nor the scaling exponents.

We first show that the Pairwise Rearrangement problem in the Single Cut-and-Join model (Bergeron, Medvedev, & Stoye, J. Comput. Biol. 2010) is $\#\textsf{P}$-complete under polynomial-time Turing reductions. Next, we show that in the Single Cut or Join model (Feijao & Meidanis, IEEE ACM Trans. Comp. Biol. Bioinf. 2011), the problem of enumerating all medians ($\#$Median) is logspace-computable ($\textsf{FL}$), improving upon the previous polynomial-time ($\textsf{FP}$) bound of Miklós & Smith (RECOMB 2015).

description: Aluminum (Al) is one of the more widespread metals in the environment and the most abundant known for its neurotoxicity in both humans and animals and could be a potential factor inducing behavioral changes, oxidative stress (OS) and loss of synapses and neurons in the hippocampal areas. The main objective of this study is to determine the impact of a single intracerebral injection of AlCl3 at different doses on the right hippocampus on affective and cognitive behaviors, on levels of OS and morphological changes in male Wistar rats. Rats were treated with a single intrahippocampal injection of 2 μL of NaCl (0.9%) (Control) or successively with 2 μL of AlCl3 at 0.5 (Al-0.5), 1 (Al-1) and 2 mg/kg (Al-2). Five days following surgical procedures, neurobehavioral tests were performed for all groups and the brain were taken to evaluate OS markers and morphological changes in the hippocampus. The results clearly demonstrate that Al induced anxiety and depressive-like behaviors, cognitive deficit, increased lipid peroxidation, nitric oxide levels, decreased superoxide dismutase activity and mediates progressive alterations characterized by disorganization in the pyramidal cellular arrangement and a decrease in neuronal density in the CA3 hippocampal area. In conclusion, a single intrahippocampal injection of Al induced anxiety-like, depression-like, memory impairment, OS and morphological alterations in the hippocampus

description: Charged Higgs boson may be produced at hadron colliders via the decay of top quarks. At the LHC, The large production cross section of top quarks pairs will make it one of the earliest channels allowing to search for physics beyond the standard model. Assuming the decay $H^+ \to τ^+ν$, previous searches have so far considered only hadronic tau decays. Here we show that by using appropriate kinematical variables (transverse mass observables), leptonic tau decays can be used as well, for both observing and possibly measuring the mass of the charged Higgs boson. This can increase the overall experimental sensitivity to charged Higgs bosons at hadron colliders.

description: Objective: We aimed to elucidate the temporal relationship between perceived social support, emotional self-disclosure and posttraumatic growth (PTG) in children. Method: The super typhoon Lekima occurred on August 10, 2019, in China. Three waves of self-report questionnaires were administered to children at 3 months (T1, N = 1596), 15 months (T2, N = 1072), and 27 months (T3, N = 483) following the typhoon. The main analysis was based on data from 351 children who completed all three waves of assessment. We constructed cross-lagged panel models to examine temporal associations between perceived social support, emotional self-disclosure, and posttraumatic growth. Results: Controlling for trauma exposure, age, gender, monthly income of family and parental marital status, results revealed that perceived social support at T1 and T2 was longitudinally related to emotional self-disclosure and PTG at T2 and T3. Emotional self-disclosure at T1 and T2 positively connected with perceived social support and PTG at T2 and T3. However, PTG did not relate to subsequent perceived social support. Mediation analyses revealed that perceived social support at T1 was positively connected with PTG at T3 through emotional self-disclosure at T2, and that emotional self-disclosure at T1 was positively connected with PTG at T3 through perceived social support at T2. Conclusions: These results demonstrated that perceived social support and emotional self-disclosure were mutually reinforcing, and both could facilitate PTG among children. Post-disaster psychological interventions could work to enrich social support resources and encourage children’s emotional self-disclosure. The study explored prospective associations of perceived social support, emotional self-disclosure, and posttraumatic growth using longitudinal data.Perceived social support and emotional self-disclosure had bidirectional associations and both can promote posttraumatic growth in children.Post-disaster psychological interventions could work to enrich social support resources and encourage children’s emotional self-disclosure.

description: This paper is the result of an intensive investigation, and analysis of the literature on psychographics. The purpose of this investigation has been to provide an improved understanding of the foundations and applications of psychographics as they relate to marketing. To this end three major aspects of psychographic literature have been considered: the theoretical foundations of psychographics, marketing applications of psychographics, and an evaluation of psychographic research. The review of literature on the subject of psychographics has lead to a conclusion that the field is not without problems. In spite of certain apparent shortcomings, however, psychographic research has been successfully applied in the area of marketing strategy development, and in the area of consumer behaviour. Improvements will be required particularly in the area of instrument design, and in the areas of reliability and validity of individual instrument items. Nevertheless, psychographic research promises to become a viable research tool. This paper closes with an assessment of future developments of psychographics.

description: Thania Petersen’s 2015 photographic series I AM ROYAL bears witness to the history of Malay people forcibly brought to South Africa from Southeast Asia, which begins from the time of enslavement to the contemporary politics of Islam in South Africa. In this thesis, I reconceptualize exhibitions as spaces of world-making and witness through historical archive research, artist interviews, and a visual analysis of I AM ROYAL. I consider the ways the past is revealed in Petersen’s work and how the images bear witness to difficult history during colonial imperialism and apartheid in the writings of I.D. Du Plessis, the demolition of District Six, and the movement to establish the District Six Museum. I argue for the ways visual languages can resist, reinterpret, and reinscribe meaning through a different set of identifiers located within Thania Petersen’s work and the interventions of queer, feminist, post-colonial and diasporic approaches in the field of museum and exhibition studies.

description: We present the discovery of two distinct classes in the Swift short duration gamma-ray bursts (S-GRBs) from the X-Ray Telescope (XRT) X-ray afterglow light curve. We find that about 40% of the Swift S-GRBs have an X-ray afterglow light curves which only lasts less than 10000 seconds after the burst trigger (hereafter short-lived S-GRBs). On the other hand, another 60% of S-GRBs have a long lasting X-ray afterglow light curve which resembles the long duration gamma-ray bursts. We also find that none of the short-lived S-GRBs shows the extended emission in the Burst Alert Telescope (BAT) energy range. We compare the burst properties for both the prompt emission and the afterglow, and discuss the possibility of different progenitors for the Swift short GRBs.

description: We have developed an accurate simulation model of the large 9 inch photomultiplier tubes (PMT) used in water-Cherenkov detectors of cosmic-ray induced extensive air-showers. This work was carried out as part of the development of the Offline simulation software for the Pierre Auger Observatory surface array, but our findings may be relevant also for other astrophysics experiments that employ similar large PMTs. The implementation is realistic in terms of geometrical dimensions, optical processes at various surfaces, thin-film treatment of the photocathode, and photon reflections on the inner structure of the PMT. With the quantum efficiency obtained for this advanced model we have calibrated a much simpler and a more rudimentary model of the PMT which is more practical for massive simulation productions. We show that the quantum efficiency declared by manufactures of the PMTs is usually determined under conditions substantially different from those relevant for the particular experiment and thus requires careful (re)interpretation when applied to the experimental data or when used in simulations. In principle, the effective quantum efficiency could vary depending on the optical characteristics of individual events.

The Halo Mass Function from Excursion Set Theory with a Non-Gaussian Trispectrum

description: A sizeable level of non-Gaussianity in the primordial cosmological perturbations may be induced by a large trispectrum, i.e. by a large connected four-point correlation function. We compute the effect of a primordial non-Gaussian trispectrum on the halo mass function, within excursion set theory. We use the formalism that we have developed in a previous series of papers and which allows us to take into account the fact that, in the presence of non-Gaussianity, the stochastic evolution of the smoothed density field, as a function of the smoothing scale, is non-markovian. In the large mass limit, the leading-order term that we find agrees with the leading-order term of the results found in the literature using a more heuristic Press-Schecther (PS)-type approach. Our approach however also allows us to evaluate consistently the subleading terms, which depend not only on the four-point cumulant but also on derivatives of the four-point correlator, and which cannot be obtained within non-Gaussian extensions of PS theory. We perform explicitly the computation up to next-to-leading order.

description: In this paper, we show that for one sign of the deformation coupling single-trace $T{\bar T}$ deformation moves the holographic screen in Gödel universe radially inward. For the other sign of the coupling it moves the holographic screen radially outward. We (thus) argue, on general grounds, that in holography (single-trace) $T{\bar T}$ deformation can be generally thought of as either moving the holographic boundary into the bulk or washing it away to infinity. In Anti-de Sitter this breaks the spacetime conformal symmetry. We further note that moving timelike holographic boundary into bulk creates a curvature singularity. In the boundary the singularity is understood by states with imaginary energies. To make the theory sensible we introduce an ultraviolet cutoff and thereby move the boundary into the bulk. In this paper we first obtain the Penrose limit of the single-trace $T{\bar T}$ deformed string background and then perform $T$-duality along a space-like isometry to obtain a class of (deformed) Gödel universes. The string background we consider is $AdS_3\times S^3\times {\cal M}_4$. The single-trace $T{\bar T}$ deformation is a particular example of the more general $O(d, d)$ transformations.

description: The $β^-$ decay $Q$-value of $^{136}$Cs ($J^π= 5^+$, $t_{1/2} \approx 13$~days) was measured with the JYFLTRAP Penning trap setup at the Ion Guide Isotope Separator On-Line (IGISOL) facility of the University of Jyväskylä, Finland. The mono-isotopic samples required in the measurements were prepared with a new scheme utilised for the cleaning, based on the coupling of dipolar excitation with Ramsey's method of time-separated oscillatory fields and the phase-imaging ion-cyclotron-resonance (PI-ICR) technique. The $Q$ value is determined to be 2536.83(45) keV, which is $\sim$4 times more precise and 11.4(20) keV ($\sim$ 6$σ$) smaller than the adopted value in the most recent Atomic Mass Evaluation AME2020. The daughter, $^{136}$Ba, has a 4$^+$ state at 2544.481(24) keV and a $3^-$ state at 2532.653(23) keV, both of which can potentially be ultralow $Q$-value end-states for the $^{136}$Cs decay. With our new ground-to-ground state $Q$ value, the decay energies to these two states become -7.65(45) keV and 4.18(45) keV, respectively. The former is confirmed to be negative at the level of $\sim$ 17$σ$, which verifies that this transition is not a suitable candidate for neutrino mass determination. On the other hand, the slightly negative $Q$ value makes this transition an interesting candidate for the study of virtual $β$-$γ$ transitions. The decay to the 3$^{-}$ state is validated to have a positive low $Q$ value which makes it a viable candidate for neutrino mass determination. For this transition, we obtained a shell-model-based half-life estimate of $2.1_{-0.8}^{+1.6}\times10^{12}$ yr.

description: [Abridged] Photoionization, whether by starlight or other sources, has difficulty in accounting for the observed spectra of the optical filaments that often surround central galaxies in large clusters. Our first paper examined whether heating by energetic particles or dissipative MHD wave can account for the observations. Here we include atomic and low-ionization regions. The model of the hydrogen atom, along with all elements of the H-like iso-electronic sequence, is now fully nl-resolved. We show how the predicted HI spectrum differs from the pure recombination case. The second update is to the rates for H^0 - H2 inelastic collisions. We now use the values computed by Wrathmall et al. The rates are often much larger. We calculate the chemistry, ionization, temperature, gas pressure, and emission-line spectrum for a wide range of gas densities and collisional heating rates. We assume that the filaments are magnetically confined and free to move along field lines so that the gas pressure is equal to that of the surrounding hot gas. A mix of clouds, some being dense and cold and others hot and tenuous, can exist. The observed spectrum will be the integrated emission from clouds with different densities and temperatures but the same pressure. We assume that the gas filling factor is given by a power law in density. The power-law index is set by matching the observed intensities of IR H2 lines relative to optical HI lines. We conclude that the filaments are heated by ionizing particles, either conducted in from surrounding regions or produced in situ by processes related to MHD waves.

description: Hepatitis C virus (HCV) infection promotes death rates all over the world. Sofosbuvir is a standard drug for the cure of HCV but unfortunately, it receives a lot of attention for its pricing problems. As a result, it is crucial to consider alternative HCV treatments that are both cost-effective and free of side effects. We report how a pharmacoinformatics-based technique was used to generate and profile certain Pyrazole analogues as novel hepatitis C virus inhibitors by exploring the PubChem drug repository for the lead molecule with further optimization. The proposed molecules all interact by filling the protein target’s binding domain to inhibit the receptor. With binding energy of −35.72 kcal/mol, compound 17e was found as a highly potent NS5B inhibitor, exceeding Sofosbuvir, the FDA-approved NS5B inhibitor with a binding energy of −30.34 kcal/mol. Additionally, the ADMET assessment of the selected molecules (17e) shows outstanding quality with a drug score of 0.74 when especially in comparison to Sofosbuvir, which has a drug score of 0.31. Future studies should therefore focus on the molecular dynamics, synthesis, in vivo testing, and in vitro evaluation of these substances to validate our hypothesis.

description: Synthetic realities are digital creations or augmentations that are contextually generated through the use of Artificial Intelligence (AI) methods, leveraging extensive amounts of data to construct new narratives or realities, regardless of the intent to deceive. In this paper, we delve into the concept of synthetic realities and their implications for Digital Forensics and society at large within the rapidly advancing field of AI. We highlight the crucial need for the development of forensic techniques capable of identifying harmful synthetic creations and distinguishing them from reality. This is especially important in scenarios involving the creation and dissemination of fake news, disinformation, and misinformation. Our focus extends to various forms of media, such as images, videos, audio, and text, as we examine how synthetic realities are crafted and explore approaches to detecting these malicious creations. Additionally, we shed light on the key research challenges that lie ahead in this area. This study is of paramount importance due to the rapid progress of AI generative techniques and their impact on the fundamental principles of Forensic Science.

description: We present a framework to treat quantum networks and all possible transformations thereof, including as special cases all possible manipulations of quantum states, measurements, and channels, such as, e.g., cloning, discrimination, estimation, and tomography. Our framework is based on the concepts of quantum comb-which describes all transformations achievable by a given quantum network-and link product-the operation of connecting two quantum networks. Quantum networks are treated both from a constructive point of view-based on connections of elementary circuits-and from an axiomatic one-based on a hierarchy of admissible quantum maps. In the axiomatic context a fundamental property is shown, which we call universality of quantum memory channels: any admissible transformation of quantum networks can be realized by a suitable sequence of memory channels. The open problem whether this property fails for some nonquantum theory, e.g., for no-signaling boxes, is posed.

description: We present new reflection models specifically tailored to model the X-ray radiation reprocessed in accretion disks around neutron stars, in which the primary continuum is characterized by a single temperature blackbody spectrum, emitted either at the surface of the star, or at the boundary layer. These models differ significantly from those with a standard power-law continuum, typically observed in most accreting black holes. We show comparisons with earlier reflection models, and test their performance in the NuSTAR observation of the neutron star 4U 1705-44. Simulations of upcoming missions such as XRISM-Resolve and Athena X-IFU are shown to highly the diagnostic potential of these models for high-resolution X-ray reflection spectroscopy. These new reflection models xillverNS, and their relativistic counterpart relxillNS, are made publicly available to the community as an additional flavor in the relxill suite of reflection models.

description: In this paper we describe a model of a four-dimensional spherically symmetric black hole in a limiting curvature theory of gravity. In this theory the Einstein-Hilbert action is modified by adding to the action terms providing inequality constraints on chosen curvature invariants. We demonstrated that in such a model, instead of formation of the curvature singularity, the spacetime remains regular in the black hole interior. For black holes with gravitational radius much larger than the radius $\ell$ of the critical curvature the obtained solutions describe a space exponentially expanding in one direction and periodically oscillating in the other two (spherical) directions.

description: Ground-based cosmic ray experiments detect cosmic ray mainly by measuring the longitudinal and lateral distribution of secondary particles produced in the extensive air shower (EAS). The EAS of cosmic ray in the knee energy region is simulated via CORSIKA software. Several simulation samples with different energy, composition and zenith angles were carried out to understand the longitudinal development of electron, muon and Cherenkov light in EAS. All the results presented were obtained assuming an observation plane at an altitude of 4400 m a.s.l. The differences of longitudinal development between electron and Cherenkov light were studied, and the reconstruction uncertainty of shower maximum for electron from Cherenkov light was estimated to be 10-15g/cm$^2$ for nuclei above 1 PeV. The performances of energy measurement and the composition discrimination ability based on longitudinal development were studied and compared with that from lateral distribution. It was found that number of electron per depth at its shower maximum has the smallest shower-to-shower fluctuations, but the shower-to-shower fluctuations of electron density measured at observation level was very close to it when the appropriate zenith angle was employed. The shower-to-shower fluctuations of shower maximum for electron is 50-55 g/cm$^2$ for proton, and 20-25 g/cm$^2$ for iron, but the composition discrimination ability between nuclei from muon density measured at observation level is much better than the shower maximum variable from longitudinal development. The hadronic model dependencies of the longitudinal development and lateral distribution were also discussed.
Practitioner experiences of delivering Video Interaction Guidance with caregivers and infants: Toward Culturally Competent Care

description: Recent reports and research have highlighted systemic racism and cultural insensitivities within maternal and perinatal services, causing harm to those using services and impacting access and engagement within care. Video Interaction Guidance (VIG) has gained an early evidence base and is rising to prominence within perinatal services. This is a relationship-based intervention that incorporates feedback of recorded clips of positive and attuned interactions between caregiver and child. Addressing cultural competence within VIG practice is pertinent to delivering effective, ethical care, that benefits all families.

The qualitative study explores VIG practitioners’ experiences of working with caregivers and infants and how they deliver culturally competent care. A reflexive thematic analysis of interviews with practitioners (N = 9) working within perinatal and parent-infant services yielded two themes (each with three subthemes): the VIG diamond, and missing families and untold stories.

The findings suggested that VIG practitioners’ practice can promote cultural competence, whilst aspects that hinder cultural considerations within their work also affect who is able to receive and benefit from the intervention. Implications for future research, practice and training, and policy are discussed.
Sul soggiorno del pittore Antonio Mancini in Irlanda nell’autunno del 1907

description: This essay focuses on the portraits painted by Antonio Mancini (Rome, 1852-1930) during his stay in Dublin, in autumn 1907. Mancini, who belonged to the Italian Verismo movement, painted several self-portraits as well as portraits of well known Irish figures including Ruth Shine (Hugh Lane’s sister), Lady Augusta Gregory and William Butler Yeats. For the Irish intellectuals he met in Dublin Mancini became a symbol of individuality, humility and sincerity. As a result, Mancini’s imagination may be interpreted in relation with that of Martin, the young protagonist of Yeats and Lady Gregory’s play The Unicorn from the Stars (1907). This study concludes with an interpretation of Mancini’s painting entitled The Maker of Figures donated by John Singer Sargent to the Dublin City Gallery The Hugh Lane in the early 1900s.

description: Based on the data release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope survey (LAMOST DR5) and the \emph{Gaia} Early Data Release 3 (\emph{Gaia} EDR3), we construct a sample containing 46,109 giant (log~$\emph{g}$ $\leqslant$ 3.5\,dex) stars with heliocentric distance d $\leqslant$ 4 kpc, and the sample is further divided into two groups of the inner ({\RGC} $$ 8.34\,kpc). The {\LZ} distributions of our program stars in the panels with different [Fe/H] and [$α$/Fe] suggest that the thick-disk consists of two distinct components with different chemical compositions and kinematic properties. For the inner region, the metal-weak thick disk (MWTD) contributes significantly when [$α$/Fe] $>+$0.2\,dex and [Fe/H] $-$0.8\,dex. However, MWTD clearly appears only when [$α$/Fe] $>+$0.2\,dex and [Fe/H] $
Mapping the magnetic field in the Taurus/B211 filamentary cloud with SOFIA HAWC+ and comparing with simulation

description: Optical and infrared polarization mapping and recent Planck observations of the filamentary cloud L1495 in Taurus show that the large-scale magnetic field is approximately perpendicular to the long axis of the cloud. We use the HAWC+ polarimeter on SOFIA to probe the complex magnetic field in the B211 part of the cloud. Our results reveal a dispersion of polarization angles of $36^\circ$, about five times that measured on a larger scale by Planck. Applying the Davis-Chandrasekhar-Fermi (DCF) method with velocity information obtained from IRAM 30m C$^{18}$O(1-0) observations, we find two distinct sub-regions with magnetic field strengths differing by more than a factor 3. The quieter sub-region is magnetically critical and sub-Alfvénic; the field is comparable to the average field measured in molecular clumps based on Zeeman observations. The more chaotic, super-Alfvénic sub-region shows at least three velocity components, indicating interaction among multiple substructures. Its field is much less than the average Zeeman field in molecular clumps, suggesting that the DCF value of the field there may be an underestimate. Numerical simulation of filamentary cloud formation shows that filamentary substructures can strongly perturb the magnetic field. DCF and true field values in the simulation are compared. Pre-stellar cores are observed in B211 and are seen in our simulation. The appendices give a derivation of the standard DCF method that allows for a dispersion in polarization angles that is not small, present an alternate derivation of the structure function version of the DCF method, and treat fragmentation of filaments.

Temperature and Time: The Effect(s) Storage Conditions Have on "Touch DNA" Deposited onto Glass Slides
Creators: name: Bozin, Kristina

Subjects: Uncategorized

description: In addition to evidence collection, how evidence is stored can be considered equally, if not even more important. It is necessary to understand what conditions it can be stored in to ensure that it will still be viable for analysis, especially when dealing with trace amounts of biological evidence. About 25 years ago, researchers had discovered that traces of DNA were being left behind on handled items, which is more commonly referred to as “touch DNA”. Since its fairly recent discovery, there is very limited literature that discusses the relationship of evidence storage and touch DNA. In this study, we deposit “charged” latent prints onto a glass slide and use both a digital and a stereomicroscope to visualize the cells left behind. The digital microscope is marketed as the Dino-Lite and uses Diamond™ Nucleic Acid Dye to stain the nucleic acids in the cells, while Trypan Blue dye stains the cytoplasm of dead cells that will be visualized by a stereomicroscope. Once the latent prints are visualized, they are swabbed, extracted, and the DNA is quantified by qPCR. Further analysis of the data will be tracked using graphs to represent any trends or relationships that appear across the varying storage conditions. The ultimate goal is to determine for up to how long and at what temperature touch DNA is still able to be recovered and used for forensic analysis in order to better streamline the process.
