THE IMPORTANCE OF THE SUBJECT OF THE CRIME IN ESTABLISHING LIABILITY FOR FORGERY, SALE OR USE OF DOCUMENTS
Creators: name: Sadullaev, Jaxongir
Publisher: name: Zenodo
Year: 2025

description: This paper examines the critical role that the subject of the crime plays in establishing legal responsibility for document forgery, sale, and fraudulent use. Through analysis of international legal frameworks, case law, and criminological perspectives, this research identifies how the varying nature of document crimes requires nuanced approaches to culpability assessment. The study explores how different legal systems attribute criminal responsibility based on the relationship between the perpetrator and the document subject matter, comparing statutory approaches across jurisdictions. Particular attention is given to intent requirements, knowledge standards, and how technological advancements have complicated traditional understandings of document crimes. The findings suggest that effective prosecution and prevention of document crimes requires legal frameworks that account for the dynamic interaction between subject matter, perpetrator intent, and technological capability.

description: On the Earth, photosynthetic organisms are responsible for the production of virtually all of the oxygen in the atmosphere. On the land, vegetation reflects in the visible, leading to a red edge that developed about 450 Myr ago and has been proposed as a biosignature for life on extrasolar planets. However, in many regions of the Earth, and particularly where surface conditions are extreme, for example in hot and cold deserts, photosynthetic organisms can be driven into and under substrates where light is still sufficient for photosynthesis. These communities exhibit no detectable surface spectral signature to indicate life. The same is true of the assemblages of photosynthetic organisms at more than a few metres depth in water bodies. These communities are widespread and dominate local photosynthetic productivity. We review known cryptic photosynthetic communities and their productivity. We link geomicrobiology with observational astronomy by calculating the disk-averaged spectra of cryptic habitats and identifying detectable features on an exoplanet dominated by such a biota. The hypothetical cryptic photosynthesis worlds discussed here are Earth-analogs that show detectable atmospheric biomarkers like our own planet, but do not exhibit a discernable biological surface feature in the disc-averaged spectrum.

description: We discuss photon-photon fusion mechanisms of dilepton production in proton-proton collisions with rapidity gap in the main detector and one forward proton in the forward proton detectors. This is relevant for the LHC measurements by ATLAS+AFP and CMS+PPS. Transverse momenta of the intermediate photons are taken into account and photon fluxes are expressed in terms of proton electromagnetic form factors and structure functions. Differential distributions in $ξ_{1/2}$, $M_{ll}$, $Y_{ll}$, $p_{t,ll}$, $M_R$ %pamietac wyjasnic M_R w tekscie are shown and the competition of different mechanisms is discussed. Both double-elastic and single-dissociative processes are included in the analysis. Different parametrizations of the structure functions are used. We discuss also mechanism with one forward $Δ^+$ isobar, or other proton resonances in the final state. The role of several cuts is studied. We also use SuperChic generator and compare corresponding results to the results of our codes. The soft rapidity gap survival factor is calculated for each contribution separately. The gap survival factor for the single-dissociative mechanism due to minijet emission into the main detector is calculated in addition. It depends on the type of contribution (fully elastic, single dissociation, double dissociation). The soft rapidity gap survival factor for the case of single proton measurement is significantly smaller than that for the inclusive case (no proton measurement). We find only weak dependence on the invariant mass of the dilepton system as well as the lepton pair transverse momentum and sizeable dependence on the pair rapidity. The latter effect is rather difficult to identify experimentally.

description: We discuss the effective potential of the conformal factor in the effective average action approach to Quantum Einstein Gravity. Without invoking any truncation or other approximations we show that if the theory has has a non-Gaussian ultraviolet fixed point and is asymptotically safe the potential has a characteristic behavior near the origin. We argue that this characteristic behavior has already been observed in numerical simulations within the Causal Dynamical Triangulation approach.

description: In this paper, we have proposed a model of accelerating Universe with binary mixture of bulk viscous fluid and dark energy. and probed the model parameters: present values of Hubble's constant $H_{0}$, Equation of state paper of dark energy $ω_{de}$ and density parameter of dark energy $(Ω_{de})_{0}$ with recent OHD as well as joint Pantheon compilation of SN Ia data and OHD. Using cosmic chronometric technique, we obtain $H_{0} = 69.80 \pm 1.64~km~s^{-1}Mpc^{-1}$ and $70.0258 \pm 1.72~km~s^{-1}Mpc^{-1}$ by restricting our derived model with recent OHD and joint Pantheon compilation SN Ia data and OHD respectively. The age of the Universe in derived model is estimated as $t_{0} = 13.82 \pm 0.33\; Gyrs$. Also, we observe that derived model represents a model of transitioning Universe with transition redshift $z_{t} = 0.7286$. We have constrained the present value of jerk parameter as $j_{0} = 0.969 \pm 0.0075$ with joint OHD and Pantheon data. From this analysis, we observed that the model of the Universe, presented in this paper shows a marginal departure from $Λ$CDM model.

description: We thank the opportunity offered by editors for this discussion and the discussants for their insightful comments and thoughtful contributions. We also want to congratulate Kallus (2020) for his inspiring work in improving the efficiency of policy learning by retargeting. Motivated from the discussion in Dukes and Vansteelandt (2020), we first point out interesting connections and distinctions between our work and Kallus (2020) in Section 1. In particular, the assumptions and sources of variation for consideration in these two papers lead to different research problems with different scopes and focuses. In Section 2, following the discussions in Li et al. (2020); Liang and Zhao (2020), we also consider the efficient policy evaluation problem when we have some data from the testing distribution available at the training stage. We show that under the assumption that the sample sizes from training and testing are growing in the same order, efficient value function estimates can deliver competitive performance. We further show some connections of these estimates with existing literature. However, when the growth of testing sample size available for training is in a slower order, efficient value function estimates may not perform well anymore. In contrast, the requirement of the testing sample size for DRITR is not as strong as that of efficient policy evaluation using the combined data. Finally, we highlight the general applicability and usefulness of DRITR in Section 3.

description: Entanglement swapping allows to establish entanglement between independent particles that never interacted nor share any common past. This feature makes it an integral constituent of quantum repeaters. Here, we demonstrate entanglement swapping with time-synchronized independent sources with a fidelity high enough to violate a Clauser-Horne-Shimony-Holt inequality by more than four standard deviations. The fact that both entangled pairs are created by fully independent, only electronically connected sources ensures that this technique is suitable for future long-distance quantum communication experiments as well as for novel tests on the foundations of quantum physics.

description: The design of attacks for cyber physical systems is critical to assess CPS resilience at design time and run-time, and to generate rich datasets from testbeds for research. Attacks against cyber physical systems distinguish themselves from IT attacks in that the main objective is to harm the physical system. Therefore, both cyber and physical system knowledge are needed to design such attacks. The current practice to generate attacks either focuses on the cyber part of the system using IT cyber security existing body of knowledge, or uses heuristics to inject attacks that could potentially harm the physical process. In this paper, we present a systematic approach to automatically generate integrity attacks from the CPS safety and control specifications, without knowledge of the physical system or its dynamics. The generated attacks violate the system operational and safety requirements, hence present a genuine test for system resilience. We present an algorithm to automate the malware payload development. Several examples are given throughout the paper to illustrate the proposed approach.

description: Recent advancements in self-supervised learning (SSL) made it possible to learn generalizable visual representations from unlabeled data. The performance of Deep Learning models fine-tuned on pretrained SSL representations is on par with models fine-tuned on the state-of-the-art supervised learning (SL) representations. Irrespective of the progress made in SSL, its generalizability has not been studied extensively. In this article, we perform a deeper analysis of the generalizability of pretrained SSL and SL representations by conducting a domain-based study for transfer learning classification tasks. The representations are learned from the ImageNet source data, which are then fine-tuned using two types of target datasets: similar to the source dataset, and significantly different from the source dataset. We study generalizability of the SSL and SL-based models via their prediction accuracy as well as prediction confidence. In addition to this, we analyze the attribution of the final convolutional layer of these models to understand how they reason about the semantic identity of the data. We show that the SSL representations are more generalizable as compared to the SL representations. We explain the generalizability of the SSL representations by investigating its invariance property, which is shown to be better than that observed in the SL representations.

description: Dictionaries are often developed using tools that save to Extensible Markup Language (XML)-based standards. These standards often allow high-level repeating elements to represent lexical entries, and utilize descendants of these repeating elements to represent the structure within each lexical entry, in the form of an XML tree. In many cases, dictionaries are published that have errors and inconsistencies that are expensive to find manually. This paper discusses a method for dictionary writers to quickly audit structural regularity across entries in a dictionary by using statistical language modeling. The approach learns the patterns of XML nodes that could occur within an XML tree, and then calculates the probability of each XML tree in the dictionary against these patterns to look for entries that diverge from the norm.

A reinvestigation of the theoretical basis for the calculation of isothermal-isobaric mass transfer in geochemical systems involving an aqueous phase
Creators: name: Perkins, Ernest Henry
Publisher: name: University of British Columbia
Year: 2010

description: Many geochemical processes involve the reaction of an aqueous phase with minerals with which the aqueous phase is not in equilibrium. Prediction of the change in the composition and in the number of moles of phases and of aqueous species as the system proceeds toward overall equilibrium is made possible by differential equations formed from mass balance, mass action, ionic strength and activity of water equations. The equations developed by Helgeson, Brown, Nigrini and Jones (1970) have been examined and alternate forms of the differential equations which constrain reaction progress have been proposed. These new equations include correct terms for the change in the mass of water, the change in the activity of water and the change in the number of moles of each endmember of the solid solution phases. The equations have been formulated to allow a more efficient algorithm for numerical evaluation. General forms for all equations are presented. A FORTRAN program for the calculation of mass transfer in an isothermal and isobaric system and a description of the program are given.

description: We report measurements of the in-plane magnetic penetration depth $λ$ in single crystals of SmFeAsO$_{1-x}$F$_y$ ($x\simeq y \simeq 0.2$) with $T_c \simeq 45$ K. We find that at low temperature $λ$ has an exponential temperature dependence which suggests that the Fermi surface is fully gapped. The magnitude of the minimum energy gap, $Δ_1=1.1\pm 0.1 k_BT_c$ at T=0 K, is significantly smaller than the BCS weak-coupling value suggesting that the gap is either strongly anisotropic or varies significantly between the different Fermi surface sheets. Our data fits well a two gap model with an additional larger gap of magnitude $Δ_2 = 1.8\pm0.2 k_BT_c$ which is associated with $\sim 80$% of the total superfluid density.

Das christliche Verständnis des Auf-dem-Weg-Seins
Creators: name: Zechner, Roswitha
Year: 2009

description: Das christliche Verständnis des AUF-DEM-WEG-SEINS wird anhand von Beispielen des Alten und Neuen Testaments, sowie des frühen Mittelalters behandelt. Die Peregrinatio von Abraham und Mose (AT), Jesus und Paulus (NT) und der iro-schottischen Wandermönche (frühes Mittelalter) wird der Wallfahrt gegenübergestellt. Es wird geschildert, wie Abraham der Aufforderung Gottes nachkommt und seiner Verheißung Glauben schenkt. Nach der Betrachtung der Kapitel Gen 12 und 15 wird noch die Prüfung des Glaubensgehorsams (Gen 22) diskutiert. Danach wird die Berufung Mose durch JHWH geschildert und die zögerliche Annahme seiner Sendung. Durch Konfliktsituationen hindurch führt der lange Weg durch die Wüste zur Theophanie am Berg Sinai. Mose wird Übermittler der Tora. Der Bundesschluss ist die Geburtsstunde Israels. Im Anschluss wird das Unterwegsein Jesu betrachtet, der lehrend und heilend das Reich Gottes verkündet. Er beruft Menschen, die wie er heimatlos und besitzlos durch das Land ziehen, und macht sie zu seinen Aposteln. Er zeigt den Weg und ist der Weg, den wir gehen sollen. Jesus sendet seine Jünger zuerst nur zu den verlorenen Schafen Israels, später in die ganze Welt, und dokumentiert so den universalen Heilswillen Gottes. In der Emmaus-Perikope veranschaulicht Lukas, dass Jesus auch nach seiner Auferstehung unser Weggefährte ist. Als zweites Beispiel aus dem Neuen Testament wird die Bekehrung und Berufung Pauli geschildert, sowie sein unermüdlicher Einsatz auf seinen Missionsreisen und das Auftreten von Anhängern und Gegnern in den von ihm gegründeten Gemeinden. Als nächster Punkt wird die peregrinatio pro deo der iro-schottischen Wandermönche behandelt und ihr Unterwegssein mit dem Aufbruch Abrahams aus seiner Heimat und der Heimatlosigkeit Jesu in Beziehung gesetzt. Danach folgt eine kurze Darstellung der Vita des heiligen Kolumban und der Gründung des Schottenstiftes zu Wien. Abschließend wird die Wallfahrt als „Gehen zu Gott“ mit genau definiertem Ziel, bestimmter Zeit und der Absicht der Heimkehr der lebenslangen Peregrinatio ohne Heimkehrabsicht gegenübergestellt. Als Beispiel für die geschichtliche Entwicklung zu einem Wallfahrtsort wird Santiago de Compostela beschrieben.

Pluralism in semantics

description: This dissertation studies and contributes to a recent trend of mathematical innovations linked to the hyperintensional revolution in formal semantics. It does so against the backdrop of a methodological pluralism that we defend in the first part of the thesis. We characterise semantics as a model-building activity and piggyback on a general pluralism about scientific models to motivate a metasemantics centered around the study of networks of distinct but complementary semantic models. The precise pluralism we endorse is two-tiered: two semantic models can bifurcate on the granularity at which meanings are modelled − the resolution each models targets − or on the techniques deployed in their respective formal apparatus − on the modelling style used to capture that target. This leads us to organise our metasemantics as a bi-dimensional cartography of semantic models. We focuses on two-component semantics − which is based on the idea that propositions are characterised both by their truth-conditions and their subject-matter. The second part of dissertation lays out the basic semantic machinery of two-component semantics and and organises its multiple implementations in the context of our two-tier pluralism. In particular, we consider both the American and the Australian plans for paradefinite negation. The third part explores various ontological modelling of truth-supporting circumstances and of aboutness-supporting topics as well as their semantic upshots. This exploration culminates in the result that particular implementations of two-component semantics lead to truthmaker semantics, a competing hyperintensional framework. This bridge between two-component and truthmaker semantics allows us to further our understanding of the preexisting American-style truthmaker semantics but also to develop an original Australianstyle truthmaker semantics.
New X-ray observations of the old nova CP Puppis and of the more recent nova V351 Pup

description: We present X-ray observations of the field containing Nova Puppis 1942 (CP Pup) and Nova Puppis 1991 (V351 Pup), done with ASCA in 1998, and with XMM-Newton in 2005. The X-ray and UV luminosity of CP Pup seem to have remained approximately constant since the last X-ray observations of the 1980'ies, while the optical luminosity has decreased. The X-ray properties of this nova are explained by a high mass white dwarf accreting at low rate, in agreement with the nova theory given the large amplitude and other characteristics of the 1942 outburst. Assuming a distance of 1600 pc, the X-ray luminosity of CP Pup is L=2.2 x 10(33) erg/s in the 0.15-10 keV range covered with EPIC, compatible with a magnetic system. The RGS grating spectrum shows a few prominent emission lines, and it is fitted with a cooling flow with mass accretion rate mdot <= 1.6 x 10(-10) msol/year. We detected also the O VII complex at 21.6-21.8 A that does not arise in the cooling flow. Most likely this feature originates in a wind or in the nova shell. The RGS and EPIC spectra are fitted only with thermal models with a very high shock temperature, T>60 keV, indicating a white dwarf with M>1.1 M(sun). The X-ray flux is modulated with the spectroscopic period of 1.47 hours detected in the optical. Since CP Pup is not an eclipsing system, this is better understood if magnetic accretion occurs: we discuss this possibility and its implications in detail. V351 Pup (N Pup 1991) was detected with XMM-Newton, but not with ASCA. It is a faint, non-super-soft X-ray source with luminosity L(x) =~ 3 x 10(31) erg/s, a factor of 50 less than measured with ROSAT in 1993.

Blue-detuned evanescent field surface traps for neutral atoms based on mode interference in ultra-thin optical fibres

description: We present and analyze a novel concept for blue-detuned evanescent field surface traps for cold neutral atoms based on two-mode interference in ultra-thin optical fibres. When two or more transverse modes with the same frequency co-propagate in the fibre, their different phase velocities cause a stationary interference pattern to establish. Intensity minima of the evanescent field at any distance from the fibre surface can be created and an array of optical microtraps can thus be obtained in the evanescent field. We discuss three possible combinations of the lowest order modes, yielding traps at one to two hundred nanometres from the fibre surface which, using a few ten milliwatts of trapping laser power, have a depth on the order of 1 mK for caesium atoms and a trapping lifetime exceeding 100 seconds. The resulting trapping geometry is of particular interest because atoms in such microtrap arrays will be coupled to any additional field propagating in the fibre via the evanescent field, thereby realising ensembles of fibre-coupled atoms.

description: First-principle electronic structure calculations have been performed in crystalline complex phases mu-Al4Mn and lambda-Al4Mn using the TB-LMTO method. These atomic structures, related to quasicrystalline structures, contain about 560 atoms in a large hexagonal unit cell. One of the main characteristic of their density of states is the presence of fine peaks the so-called "spiky structure". From multiple-scattering calculations in real space, we show that these fine peaks are not artifacts in ab-initio calculations, since they result from a specific localization of electrons by atomic clusters of different length scales.

Let $S \subset \R^{\ell+k}$ be a semi-algebraic set defined by a Boolean formula without negations, with atoms $P=0, P \geq 0, P \leq 0, P \in {\mathcal P} \cup {\mathcal Q}$. We describe an algorithm for computing the the Betti numbers of $S$. The complexity of the algorithm is bounded by $(\ell s m d)^{2^{O(m+k)}}$. The complexity of the algorithm interpolates between the doubly exponential time bounds for the known algorithms in the general case, and the polynomial complexity in case of semi-algebraic sets defined by few quadratic inequalities known previously. Moreover, for fixed $m$ and $k$ this algorithm has polynomial time complexity in the remaining parameters.

description: We use light microscopy to investigate the aging dynamics of a glass made of closely packed soft spheres, following a rapid transition from a fluid to a solid-like state. By measuring time-resolved, coarse-grained displacements fields, we identify two classes of dynamical events, corresponding to reversible and irreversible rearrangements, respectively. The reversible events are due to the small, experimentally unavoidable fluctuations of the temperature imposed to the sample, leading to transient thermal expansions and contractions that cause shear deformations. The irreversible events are plastic rearrangements, induced by the repeated shear cycles. We show that the displacement due to the irreversible rearrangements grows linearly with time, both on average and at a local level. The velocity associated with this ballistic motion decreases exponentially with sample age, accounting for the observed slowing down of the dynamics. The displacement field due to the irreversible rearrangements has a vortex-like structure and is spatially correlated over surprisingly long distances.

description: We study hard $1\to 2$ final-state parton splittings in the medium, and put special emphasis on calculating the Wilson line correlators that appear in these calculations. As partons go through the medium their color continuously rotates, an effect that is encapsulated in a Wilson line along their trajectory. When calculating observables, one typically has to calculate traces of two or more medium-averaged Wilson lines. These are usually dealt with in the literature by invoking the large-$N_c$ limit, but exact calculations have been lacking in many cases. In our work, we show how correlators of multiple Wilson lines appear, and develop a method to calculate them numerically to all orders in $N_c$. Initially, we focus on the trace of four Wilson lines, which we develop a differential equation for. We will then generalize this calculation to a product of an arbitrary number of Wilson lines, and show how to do the exact calculation numerically, and even analytically in the large-$N_c$ limit. Color sub-leading corrections, that are suppressed with a factor $N_c^{-2}$ relative to the leading scaling, are calculated explicitly for the four-point correlator and we discuss how to extend this method to the general case. These results are relevant for high-$p_T$ jet processes and initial stage physics at the LHC.

description: We show quantitatively that tiny amounts of copolymer that decorate a oil/water interfaces can greatly enhance the stability of swollen surfactant hexagonal phases, comprising oil tubes regularly arranged in a water matrix. Such soft composite materials, whose both radius of the tubes and water channel between the tubes can be controlled independently over large ranges, offer a potential interest for the synthesis of mesoporous materials.
Motivationsanalyse von Touristen in Wien
Creators: name: Krammer, Florian
Year: 2009

description: Studien, die sich mit dem Thema Städtetourismus insbesondere in Verbindung mit Motivation auseinandersetzen, sind äußerst selten. Die vorliegende Arbeit untersucht daher Zusammenhänge zwischen Motiven (Intellektuelle-, Soziale-, Kompetenz-Macht- und Stimulusvermeidungsmotiven) und Urlaubsaktivitäten von Touristen in Wien. Zur Erfassung der Motive wird die „Leisure Motivation Scale“ von Beard und Ragheb (1983) in adaptierter Form eingesetzt. Neben den Motiven werden soziodemografische und reisebezogene Variablen auf ihre Bedeutung für Urlaubsaktivitäten überprüft. Aus marktwirtschaftlichen Interessen werden die Urlauber anhand einer Clusteranalyse aufgrund ihre Urlaubsaktivitäten in drei Typen (Sightseeing-, Sport und Fun-, Intellektueller Typ) eingeteilt, wobei sich mittels Diskriminanzanalyse zeigt, dass 64,6 % der Urlauber aufgrund weniger Variablen (Sozial Motiv, gesamte Aufenthaltsdauer, Alter) zu den Urlaubstypen richtig zugeordnet werden können.

description: We give an analytical solution representing circular magnetic monopole loops joining a pair of merons in the four-dimensional Euclidean SU(2) Yang-Mills theory. This is achieved by solving the differential equation for the adjoint color (magnetic monopole) field in the two--meron background field within the recently developed reformulation of the Yang-Mills theory. Our analytical solution corresponds to the numerical solution found by Montero and Negele on a lattice. This result strongly suggests that a meron pair is the most relevant quark confiner in the original Yang-Mills theory, as Callan, Dashen and Gross suggested long ago.

The development of a completely automated oxygen isotope mass spectrometer
Creators: name: Ahern, Timothy Keith
Publisher: name: University of British Columbia
Year: 2010

description: A completely automated mass spectrometer system has been developed to measure the oxygen isotope ratio of carbon dioxide samples. The system has been shown to have a precision of 0.03°/oo, which is comparable to that quoted for any other system in the world. In addition, the facility is capable of analyzing over one hundred samples per day. The system uses an Interdata minicomputer as the primary controller. The minicomputer monitors the quality of analyses, on-line, and thereby insures that all DEL values are measured to at least 0.04°/oo. Host of the sophistication resides in intelligent controllers within the mass spectrometer console. This design gives a technician considerable power when operating the system in a manual mode. The intelligence of the system is contained within hardware circuits, software within the minicomputer and firmware written for a Motorola 6802 microprocessor. A major contribution of this thesis has been the design and installation of an automated mass spectrometer inlet system. A microprocessor based inlet system controller maximizes the throughput of carbon dioxide samples within the inlet system. The inlet system normally contains four different aliquots of carbon dioxide and introduces these samples to the mass spectrometer, in proper sequence, through a single mass spectrometer admittance leak. The system has been used in the analysis of 111 samples of ice taken from the Steele Glacier, Yukon Territory. The samples taken from a vertical borehole, displayed a sawtooth variation of the oxygen isotope ratio with depth. The data have been explained by a physical model described in an appendix to this thesis. If our interpretation is correct, the isotopic variations have recorded at least four surges of the Steele Glacier.

Gesundheitsbezogene Lebensqualität, Kohärenzgefühl und Depressivität bei Cannabiskonsum
Creators: name: Steger, Daniela
Year: 2010

description: Ziel: Das Ziel dieser Studie war, das (psychische) Gesundheitsrisiko bei Cannabiskonsum auf emotionaler und kognitiver Ebene zu untersuchen. Operationalisiert wurde dies mit der gesundheitsbezogenen Lebensqualität (HrQoL), dem Ausmaß der Depressivität sowie dem Kohärenzgefühl. Methoden: Mittels Online-Fragebogen wurden 245 Personen (vorwiegend Studenten) untersucht und dabei die Short Form 36, das Beck-Depressions-Inventar und die Sense of Coherence Scale (Kurzform SOC-L9) eingesetzt. Anhand der DSM-IV-Kriterien für substanzbezogene Störungen wurden Cannabiskonsumente in die Gruppen Gebraucher, Missbraucher und Abhängige eingeteilt. Deren Ergebnisse wurden mittels einfaktorieller ANOVA mit jenen von Nichtkonsumenten verglichen, die sie wiederum in Ex-Konsumenten und Nie-Konsumenten (Personen, die Cannabis nicht einmal probiert haben) unterteilten. Mittels binär-logistischer Regression wurde berechnet, ob es Prädiktoren für die Entwicklung einer Abhängigkeit gibt. Ergebnisse: Cannabisabhängige hatten in allen Variablen signifikant schlechtere Ergebnisse als Cannabisexperimentierer, insbesondere in Bezug auf die Depressionsausprägung, das Kohärenzgefühl sowie in den drei Dimensionen der gesundheitsbezogenen Lebensqualität Allgemeine Gesundheitswahrnehmung, Vitalität und psychisches Wohlbefinden. Das psychische Wohlbefinden und die Häufigkeit des Konsums erwiesen sich als signifikante Prädiktoren, doch die Korrelationen waren insgesamt eher niedrig. Schlussfolgerungen: Ausschließlich die Abhängigkeit von Cannabinoiden, nicht aber andere Konsummuster (Gebrauch und auch Missbrauch) könnten problematisch für die psychische Gesundheit sein. Allerdings ist die Kausalität nicht geklärt; vermutlich sind Drittvariablen von Bedeutung, die Substanz selbst führt von der Pharmakologie her nicht nachweislich zu psychischen Gesundheitsfolgen.

THE ADMISSIBILITY OF EVIDENCE OBTAINED IN THE PROCESS OF ENSURING THE SAFETY OF PARTICIPANTS IN CRIMINAL PROCEEDINGS: A COMPARATIVE LEGAL ANALYSIS
Creators: name: Mamatalieva, Sh.Kh.
Publisher: name: Zenodo
Year: 2025

description: The safety of participants in criminal proceedings has become a paramount concern across jurisdictions, especially in cases involving organized crime, terrorism, or vulnerable witnesses. While protective measures such as anonymity, witness relocation, and special interrogation techniques are essential, they often raise complex questions regarding the admissibility and reliability of evidence obtained under such circumstances. This article examines the legal standards and practices concerning the admissibility of evidence collected during protective procedures, with a focus on comparative developments in the United States, the United Kingdom, the European Union, and international criminal law. Through an analysis of landmark cases and legislative frameworks, the article identifies emerging trends, legal dilemmas, and potential safeguards to ensure both fair trial rights and the protection of justice system participants.

description: For points in SUSY parameter space where the sneutrino is lighter than the lightest chargino and next-to-lightest neutralino, its direct mass determination from sneutrino pair production process at e+e- collider is impossible since it decays invisibly. In such a scenario the sneutrino can be discovered and its mass determined from measurements of two-body decays of charginos produced in pairs at the ILC. Using the event generator WHIZARD we study the prospects of measuring sneutrino properties in a realistic ILC environment. In our analysis we include beamstrahlung, initial state radiation, a complete account of reducible backgrounds from SM and SUSY processes, and a complete matrix-element calculation of the SUSY signal which encompasses all irreducible background and interference contributions. We also simulate photon induced background processes using exact matrix elements. Radiation effects and the cuts to reduce background strongly modify the edges of the lepton energy spectra from which the sneutrino and chargino mass are determined. We discuss possible approaches to measure the sneutrino mass with optimal precision.
