description: High yields of phase-pure K3[Fe2S4] are obtained using a fast, straight-forward, and efficient synthetic technique starting from the binary precursors K2S and FeS, and elemental sulphur. The compound indicates soft ferrimagnetic characteristics with magnetization of 15.23 A m2 kg−1 at 300 K due to the mixed valence of FeII/FeIII. Sintering at different temperatures allows the manipulation of the microstructure as well as the ratio of grains to grain boundaries. This results in a variation of dielectric and impedance properties. Samples sintered at 923 K demonstrate a dielectric constant (κ) of around 1750 at 1 kHz, which lies within the range of well-known high-κ dielectric materials, and an ionic conductivity of 4 × 10−2 mS cm−1 at room temperature. The compound has an optical band gap of around 2.0 eV, in agreement with tailored quantum chemical calculations. These results highlight its potential as a material comprising non-toxic and abundant elements for electronic and magnetic applications.

description: The behavior of the charm and bottom structure functions ($F_{k}^{i}(x,Q^{2})$, i=c,b; k=2,L) at small-$x$ is considered with respect to the hard-Pomeron and saturation models. Having checked that this behavior predicate the heavy flavor reduced cross sections concerning the unshadowed and shadowed corrections. We will show that the effective exponents for the unshadowed and saturation corrections are independent of $x$ and $Q^{2}$, and also the effective coefficients are dependent to $\ln{Q^{2}}$ compared to Donnachie-Landshoff (DL) and color dipole (CD) models.
Interpretations of quantum theory: A map of madness

Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Motivated by some recent news, a journalist asks a group of physicists: "What's the meaning of the violation of Bell's inequality?" One physicist answers: "It means that non-locality is an established fact". Another says: "There is no non-locality; the message is that measurement outcomes are irreducibly random". A third one says: "It cannot be answered simply on purely physical grounds, the answer requires an act of metaphysical judgement". Puzzled by the answers, the journalist keeps asking questions about quantum theory: "What is teleported in quantum teleportation?" "How does a quantum computer really work?" Shockingly, for each of these questions, the journalist obtains a variety of answers which, in many cases, are mutually exclusive. At the end of the day, the journalist asks: "How do you plan to make progress if, after 90 years of quantum theory, you still don't know what it means? How can you possibly identify the physical principles of quantum theory or expand quantum theory into gravity if you don't agree on what quantum theory is about?" Here we argue that it is becoming urgent to solve this too long lasting problem. For that, we point out that the interpretations of quantum theory are, essentially, of two types and that these two types are so radically different that there must be experiments that, when analyzed outside the framework of quantum theory, lead to different empirically testable predictions. Arguably, even if these experiments do not end the discussion, they will add new elements to the list of strange properties that some interpretations must have, therefore they will indirectly support those interpretations that do not need to have all these strange properties.

Novel intraoperative device to reduce colorectal recurrence following surgical resection
Creators: name: Warner, Samuel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Recurrence of colorectal cancer following surgical resection continues to be a major therapeutic
challenge. As local recurrence of the cancer may progress into metastatic disease, there is strong
interest in mitigating recurrence to improve patient survivability. Advancements in
radiotherapies, brachytherapy in particular, have shown promise in reducing the recurrence of
other types of cancer, such as those of the prostate. The large surface area, complex geometries
of colorectal tumors and their close proximity to solid organs, however, limit the use of such
radiotherapies. Therefore it may be beneficial to look toward other avenues of treatment to
reduce colorectal cancer recurrence.

description: It is well known that Strassen and Winograd algorithms can reduce the computational costs associated with dense matrix multiplication. We have already shown that they are also very effective for software-based multiple precision floating-point arithmetic environments such as the MPFR/GMP library. In this paper, we show that we can obtain the same effectiveness for double-double (DD) and quadruple-double (QD) environments supported by the QD library, and that parallelization can increase the speed of these multiple precision matrix multiplications. Finally, we demonstrate that our implemented parallelized Strassen and Winograd algorithms can increase the speed of parallelized LU decomposition.
Richard Strauss's Eine Alpensinfonie: An Analysis of Origins, Topics, and Symphonic Characteristics
Creators: name: Minnick, Jonathan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This thesis addresses Richard Strauss’s Eine Alpensinfonie’s unsettled program and
assesses multiple accounts of the portrayal of the program and the evidence provided by each. In
addition, I explore the ideas of landscape in relation to Eine Alpensinfonie and how Strauss
manages the alpine landscape as played out through his music. This exploration is substantiated
by a thorough melodic analysis of the piece, which has organized themes hierarchically and
given them titles based on their arrangement, style, and position within the piece.
There are multiple questions that this thesis addresses in relation to the program and the
thematic material of Eine Alpensinfonie. Numerous Strauss scholars have provided suggestions
on how the program could be interpreted, though there has not been a definite answer to the
question of what the program is for this piece of music. The question that I ask is what are some
of the different assertions made about the program of Eine Alpensinfonie and do they hold up to
critical analysis of other evidence found throughout my own research. The thematic material in
the piece has been analyzed thoroughly by Rainer Bayreuther in his comprehensive work on Eine
Alpensinfonie, though I am adding to what he has already generated. The central questions
related to the thematic material are, do the themes and motives match or shape the program of
the piece and how do ideas on topic theory interact with the structure and how does the thematic
material relate to the ideas on topic theory in the 19th and 20th centuries.

description: The interpretation of quantum theory is one of the longest-standing debates in physics. Type I interpretations see quantum probabilities as determined by intrinsic properties of the observed system. Type II see them as relational experiences between an observer and the system. It is usually believed that a decision between these two options cannot be made simply on purely physical grounds but requires an act of metaphysical judgment. Here we show that, under some assumptions, the problem is decidable using thermodynamics. We prove that type I interpretations are incompatible with the following assumptions: (i) The choice of which measurement is performed can be made randomly and independently of the system under observation, (ii) the system has limited memory, and (iii) Landauer's erasure principle holds.

description: We consider $10$-dimensional gravitational model with $SO(6)$ Yang-Mills field, Gauss-Bonnet term and $Λ$-term. We study so-called cosmological type solutions defined on product manifold $M = R \times R^3 \times K$, where $K$ is $6d$ Calabi-Yau manifold. By putting the gauge field 1-form to be coinciding with 1-form spin connection on $K$, we obtain exact cosmological solutions with exponential dependence of scale factors (upon $t$-variable), governed by two non-coinciding Hubble-like parameters: $H >0$, $h$, obeying $ H + 2 h \neq 0$. We also present static analogs of these cosmological solutions (for $H \neq 0$, $h \neq H$ and $ H + 2 h \neq 0$). The islands of stability for both classes of solutions are outlined.

description: We have updated our analysis of the 9-year WMAP data using the collection of polarization maps looking for the presence of additional evidence for a finite 'cosmic ray foreground' for the CMB. We have given special attention to high Galactic latitudes, where the recent BICEP2 findings were reported. The method of examining the correlation with the observed gamma ray flux proposed in our earlier papers and applied to the polarization data shows that the foreground related to cosmic rays is still observed even at high Galactic altitudes and conclusions about gravitational waves are not yet secure. Theory has it that there is important information about inflationary gravitational waves in the fine structure of the CMB polarization properties (polarization vector and angle) and it is necessary to examine further the conclusions that can be gained from studies of the CMB maps, in view of the disturbing foreground effects.

The Human GI Microbial GUSome, a Constellation of Drug Targets in the Microbiome
Creators: name: D'Agostino, Emma
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Drugs and other potentially harmful chemicals are detoxified by glucuronidation in the liver and sent to the gastrointestinal tract (GI) for elimination. β-glucuronidase (GUS) enzymes expressed by the GI microbiota can then cleave off the glucuronide, reactivating the compounds and causing GI toxicity. In the best-characterized example of such toxicity, reactivation of the chemotherapeutic irinotecan generates its dose-limiting toxicity. We developed potent, non-lethal inhibitors that selectively target bacterial GUS activity and effectively alleviate irinotecan GI toxicity in mice.
Ulrike Meinhof's Bambule: Performing Politics in the Electronic Public Sphere
Creators: name: Wallace, Amelia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: In the preeminent text describing the history of the Baader Meinhof Group, Der Baader Meinhof Komplex, Stefan Aust describes Ulrike Meinhof’s descent into the terrorist underground succinctly:
Am 14. Mai 1970 um 9.00 Uhr morgens war es soweit. Andreas Baader wurde mit Waffengewalt aus dem Institut für Soziale Fragen im Westberliner Stadtteil Dahlem befreit…Baader und seine Befreier entkamen. Mit dem Sprung aus dem Fenster des Instituts für Soziale Fragen beendete Ulrike Meinhof ihre journalistische Karriere und ging in den Untergrund.
In the 2008 film of the same name based on Aust’s book, director Uli Edel fills in the emotional dynamic of this scene missing from Aust’s account. He focuses on Meinhof’s panic and indecision in particular. As her accomplices enter and violently free Baader, the camera switches back and forth from Meinhof’s face to the chaos erupting around her.
She realizes she has two options: remain in the room and feign surprise when the police arrive, as planned, or follow her accomplices through the window, join the terrorist underground, and leave
any chance of continuing her journalistic career. Of course, she chooses to jump through the window, and much scholarship has been dedicated to understanding her life and work after her move into the underground. Yet her ambivalence towards leaving in this scene led me to the two principle questions that motivated this project: Why did Ulrike Meinhof decide to follow Andreas Baader and Gudrun Ensslin through that window? Further, what would have become of Meinhof had she chosen to continue legitimate work as a journalist and public figure?
To answer these questions, I will discuss the television film, Bambule, for which Meinhof wrote the screenplay and created a radio feature in preparation. The film, set to air ten days after Baader’s escape on May 24, 1970, was quickly removed from the network’s schedule because of Meinhof’s terrorist connections. It would not be shown on German television until the 1990s. In the following two chapters, I will investigate how Meinhof used two forms of electronic media, radio and television, differently to convey a political message. These works represent a transition for Meinhof as she moved from print journalism to electronic media and created her first fictional work. Analysis of these works give us an indication of what direction her career and political legacy could have taken had she chosen to sit back down in the Institut für Soziale Fragen and disavow her connection to Baader’s escape. Additionally, Meinhof’s attitude towards these works, particularly towards their perceived weaknesses, helps to explain how her decision to jump through the window might not have been as spontaneous as it seems in Edel’s Der Baader Meinhof Komplex.
Cosolute effects on a domain-swapped homodimer
Creators: name: Perez Goncalves, Gerardo
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The cellular interior is crowded, with macromolecules occupying from 10% to 40% of the volume. Under these conditions, proteins experience hard-core repulsions and chemical interactions with cytoplasmic components. Hard-core repulsions stabilize globular proteins, whereas chemical interactions can be either repulsive and stabilizing, or attractive and destabilizing. Several studies have considered crowding effects on globular protein stability, but there are few such studies on protein-protein interactions. We used 19F NMR to quantify the effects (298 K, pH 7.5) of macromolecular cosolutes on a variant of the B1 domain of protein G (GB1) that forms a domain-swapped homodimer. At a concentration of 200 g/L, the monomer of the synthetic polymer polyethylene glycol (PEG) destabilizes the dimer by 0.30 kcal/mol, while at the same concentration, 3.3 kDa-, 8 kDa- and 20 kDa- PEG stabilize the dimer by 0.08, 0.39 and 0.4 kcal/mol, respectively. These data indicate a stabilizing, but saturable, macromolecular effect. We also showed that the physiologically-relevant cosolutes bovine serum albumin (BSA) and lysozyme have opposite effects; the former (at 100 g/L) stabilizes the dimer by 0.51 kcal/mol, and the latter (at 50 g/L) destabilizes the dimer by 0.12 kcal/mol. These results can be explained by the differences in charge. BSA has the same charge as GB1, resulting in stabilizing repulsions. Lysozyme and GB1 have complementary charges, resulting in destabilizing attractions. The differing effects of PEG and the protein cosolutes indicate that synthetic polymers are poor mimics of the cellular interior because they do not account for chemical interactions found in cells.

In our recent analysis we utilize the recent available data and consequently include more data than what we did in our previous analysis. we obtain good agreements between our results for the polarized parton densities and nucleon structure functions with all available experimental data and some common parametrization models.

Inference of the ocean sound speed profile using ambient vertical beam noise

Year: 2023
Subjects: Ocean acoustics

description: This dissertation introduces a novel passive acoustic method for estimating the water column sound speed using the directionality of the ambient noise field measured with a vertical line array. In the absence of anthropogenic and biological sources, wind/wave sea surface interaction is the dominant source of mid-frequency noise insonifying the undersea environment. The resulting vertical noise field is anisotropic, with the directionality of the noise environment dependent on the paths of noise from the surface to the receiver. Changes in receiver depth, and associated sound speed, affect the level of ambient vertical noise at shallow elevation angles, providing the sensitivity necessary to acoustically estimate the in situ sound speed profile. Application of a clustering algorithm to an historical set of measured sound speed profiles allows for the characterization of common regional profiles. The scale and resulting undersampled nature of the ocean environment prompts the development of a novel interpolation scheme that retains acoustically important sound speed features in the region between available measurements. Motivated by the vertical stratification and motion of the water column, the interpolation scheme determines an appropriate vertical shift in depth to align sound speed features, enabling persistent features in the interpolated range between measurements. The developed method for inferring the sound speed profile combines sparse measurements of the vertical noise environment with an historical set of measured sound speed profiles and the vertical shifting method to provide an estimate of the in situ sound speed profile, with modeled results having error on the order of common active acoustic inversion methods. Finally, the method is applied to a low-frequency vertical line array data set, with results suggesting the array aperture was insufficient, and that further experimentation is needed.

description: The formalism of matrix product states is used to perform a numerical study of 1+1 dimensional QED -- also known as the (massive) Schwinger model -- in the presence of an external static `quark' and `antiquark'. We obtain a detailed picture of the transition from the confining state at short interquark distances to the broken-string `hadronized' state at large distances and this for a wide range of couplings, recovering the predicted behavior both in the weak and strong coupling limit of the continuum theory. In addition to the relevant local observables like charge and electric field, we compute the (bipartite) entanglement entropy and show that subtraction of its vacuum value results in a UV-finite quantity. We find that both string formation and string breaking leave a clear imprint on the resulting entropy profile. Finally, we also study the case of fractional probe charges, simulating for the first time the phenomenon of partial string breaking.

description: The molecular regulation of sleep in avian migrants is still obscure. We thus investigated this in migratory redheaded buntings, where four life-history states (LHS; i.e. non-migratory, pre-migratory, migratory and refractory state) were induced. There was increased night-time activity (i.e. Zugunruhe) during the migratory state with reduced day-time activity. The recordings of the sleep–wake cycle in buntings showed increased night-time active wakefulness coupled with drastically reduced front and back sleep during migratory phase. Interestingly, we found the buntings to feed and drink even after lights-off during migration. Gene expression studies revealed increased hypothalamic expression of glucocorticoid receptor (nr3c1), and pro-inflammatory cytokines (il1b and il6) in pre-migratory and migratory states, respectively, whereas in brainstem Ca2+/calmodulin-dependent protein kinase 2 (camk2) was upregulated during the migratory state. This suggested a heightened pro-inflammatory state during migration which is a feature of chronic sleep loss, and a possible role of Ca2+ signalling in promoting wakefulness. In both the hypothalamus and brainstem, the expression of melatonin receptors (mel1a and mel1b) was increased in the pre-migratory state, and growth hormone-releasing hormone (ghrh, known to induce sleep) was reduced during the migratory state. The current results demonstrate key molecules involved in the regulation of sleep–wake cycle across LHS in migratory songbirds.

description: Steering torque is a very important quantity for the driver feeling. In fact, it gives the driver an idea of the road adherence condition during driving. Several models have been developed to simulate shear forces at the contact patch, most of them are based on semi-empirical tire models that account for slip and slip angles. They have good reliability when speed is high enough. At very low speed, like in parking, these models suffer from both reliability and numerical issues. This paper presents a model to compute the steering moment due to contact-patch friction at any longitudinal speed including pivot steering condition. In particular, it supplements the pivot steering model with a novel exponential decay of moment model to simulate for various rolling speeds of the wheel. The decay rate found to be dependent upon contact-patch geometry and rolling speed.
Investigating the Seismic Gap in North Carolina: A Seismic Survey of the Deep River Basin in Central North Carolina
Creators: name: Portner, Daniel Evan

Year: 2014

description: The Deep River Basin is one of a series of Triassic rift basins along the east coast of the
United States that make up the Newark Supergroup (Olsen et al. 1989). The supergroup of
basins formed from preliminary extension during the breakup of Pangaea before the Atlantic
Ocean began to spread (Olsen et al. 1989). The Deep River Basin consists of three sub-basins,
the Wadesboro sub-basin, the Sanford sub-basin, and the Durham sub-basin (Olsen et al. 1989).
A bed of shale and coal known as the Cumnock formation surfaces along the northern margin of
the Sanford sub-basin (Olsen et al. 1991). In the past, this has been exploited by coal mining
operations. More recently, however, it has been the focus of local gas companies. Recent
legislation suggests that hydraulic fracturing operations may occur in the Sanford sub-basin in
the near future. While hydraulic fracturing itself does not cause seismicity large enough to be
recorded by the type of data analyzed here, the reinjection of wastewater into basement rocks has
been linked to more significant seismicity in certain areas. Although it is unknown whether or
not hydraulic fracturing or the associated reinjection of wastewater will occur in the Sanford sub-basin,
a baseline of natural seismicity can be recorded before operations to be used for any
comparative studies of seismicity.
Worst-case error bounds for the super-twisting differentiator in presence of measurement noise

description: The super-twisting differentiator, also known as the first-order robust exact differentiator, is a well known sliding mode differentiator. In the absence of measurement noise, it achieves exact reconstruction of the time derivative of a function with bounded second derivative. This note proposes an upper bound for its worst-case differentiation error in the presence of bounded measurement noise, based on a novel Lipschitz continuous Lyapunov function. It is shown that the bound can be made arbitrarily tight and never exceeds the true worst-case differentiation error by more than a factor of two. A numerical simulation illustrates the results and also demonstrates the non-conservativeness of the proposed bound.

description: A classical-kind phase-space formalism is developed to address the tiny intrinsic dynamical deviation from what is predicted by Wilczek-Zee theorem during quantum adiabatic evolution on degeneracy levels. In this formalism, the Hilbert space and the aggregate of degenerate eigenstates become the classical-kind phase-space and a high-dimensional subspace in the phase-space, respectively. Compared with the previous same study by a different method, the current result is qualitatively different in that the first-order deviation derived here is always perpendicular to the degeneracy subspace. A tripod scheme Hamiltonian with two degenerate dark states is employed to illustrate the adiabatic deviation with degeneracy levels.

description: We report on the observation of optical spin-controlled modes from a quasicrystalline metasurface as a result of an aperiodic geometric phase induced by anisotropic subwavelength structure. When geometric phase defects are introduced in the aperiodic structured surface, the modes exhibit polarization helicity dependence resulting in the optical spin-Hall effect. The radiative thermal dispersion bands from a quasicrystal structure were studied where the observed bands arise from the optical spin-orbit interaction induced by the aperiodic space-variant orientations of anisotropic antennas. The optical spin-flip behavior of the revealed modes that arise from the geometric phase pickup was experimentally observed within the visible spectrum by measuring the spin-projected diffraction patterns. The introduced ability to manipulate the light-matter interaction of quasicrystals in a spin-dependent manner provides the route for molding light via spin-optical aperiodic artificial planar surfaces.

Assuming that $α$ has a density function of the form $ψ(x)(1 - x)^β$, $x\in(0,1)$, with $\lim_{x\uparrow 1}ψ(x) = ψ_1 \in(0,\infty)$, different limits of appropriately centered and scaled aggregated partial sums are shown to exist for $β\in(-1,0)$, $β= 0$, $β\in(0,1)$ or $β\in(1,\infty)$, when taking first the limit as $N\to\infty$ and then the time scale $n\to\infty$, or vice versa. In fact, we give a partial solution to an open problem of Pilipauskaite and Surgailis (2014) by replacing the random-coefficient AR(1) process with a certain randomized INAR(1) process.

description: Storing electrical energy for long periods and transporting it over long distances is an essential task of the necessary transition to a CO$_2$-free energy economy. An oxidation-reduction cycle based on iron and its oxides represents a very promising technology in this regard. The present work assesses the potential of converting an existing modern coal-fired power plant to operation with iron. For this purpose, a systematic retrofit study is carried out, employing a model that balances all material and energy fluxes in a state-of-the-art coal-fired power plant. Particular attention is given to components of the burner system and the system$'$s heat exchanger. The analysis provides evidence that main components such as the steam generator and steam cycle can be reused with moderate modifications. Major modifications are related to the larger amounts of solids produced during iron combustion, for instance in the particle feeding and removal systems. Since the high particle densities and lower demand for auxiliary systems improve the heat transfer, the net efficiencies of iron operation can be one to two percentage points better than coal operation, depending on operating conditions. This new insight can significantly accelerate the introduction of this innovative technology by guiding future research and the development of the retrofit option.

description: Recent experiments access the time-resolved photoelectron signal originating from plasmon satellites in correlated materials and address their build-up and decay in real time. Motivated by these developments, we present the Kadanoff-Baym formalism for the nonequilibrium time evolution of interacting fermions and bosons. In contrast to the fermionic case the bosons are described by second-order differential equations. Solution of the bosonic Kadanoff-Baym equations - which is the central ingredient of this work - requires substantial modification of the usual two-times electronic propagation scheme. The solution is quite general and can be applied to a number of problems, such as the interaction of electrons with quantized photons, phonons and other bosonic excitations. Here, the formalism is applied to the photoemission from a deep core hole accompanied by plasmon excitation. We compute the time-resolved photoelectron spectra and discuss the effects of intrinsic and extrinsic electron energy losses and their interference.

description: We assemble 121 spectroscopically-confirmed halo carbon stars, drawn from the literature, exhibiting measurable variability in the Catalina Surveys. We present their periods and amplitudes, which are used to estimate distances from period-luminosity relationships. The location of the carbon stars - and their velocities when available - allow us to trace the streams of the Sagittarius (Sgr) dwarf spheroidal galaxy. These are compared to a canonical numerical simulation of the accretion of Sgr. We find that the data match this model well for heliocentric distances of 15-50 kpc, except for a virtual lack of carbon stars in the trailing arm just north of the Galactic Plane, and there is only tentative evidence of the leading arm south of the Plane. The majority of the sample can be attributed to the Sgr accretion. We also find groups of carbon stars which are not part of Sgr; most of which are associated with known halo substructures. A few have no obvious attribution and may indicate new substructure. We find evidence that there may be a structure behind the Sgr leading stream apocentre, at ~100 kpc, and a more distant extension to the Pisces Overdensity also at ~100 kpc. We study a further 75 carbon stars for which no good period data could be obtained, and for which NIR magnitudes and colours are used to estimate distances. These data add support for the features found at distances beyond 100 kpc.

description: In the last years, Distributed Visualization over Personal Computer (PC) clusters has become important for research and industrial communities. They have made large-scale visualizations practical and more accessible. In this work we survey Distributed Visualization techniques aiming at compiling last decade's literature on the use of PC clusters as suitable alternatives to high-end workstations. We review the topic by defining basic concepts, enumerating system requirements and implementation challenges, and presenting up-to-date methodologies. Our work fulfills the needs of newcomers and seasoned professionals as an introductory compilation at the same time that it can help experienced personnel by organizing ideas.
Potential energy surfaces for electron dynamics from a model of localized Gaussian wave packets with valence-bond spin-coupling: high-harmonic generation spectra from H and He atoms

description: Potential energy surfaces of electron dynamics (ePES) are constructed from a model of localized electron wave packets (eWP) with non-orthogonal valence-bond (VB) spin coupling and applied to quantum dynamics simulations of high harmonic generation (HHG) spectra of hydrogen and helium atoms induced by intense laser pulses. The dynamics of the single electron on the ePES is calculated by numerically solving the time-dependent Schrodinger equation. The results reasonably reproduce previous studies. The dynamics of the electron wave function, dipole moment and dipole acceleration were analyzed by comparing one- and two-dimensional calculations. It was found that the main part of the wave function remains within a few Bohrs of the nuclear position, while the part of the wave function that is several orders of magnitude smaller in probability density, which escapes the laser-induced potential barrier by quantum tunneling effect, mainly contributes to the HHG.

description: We have measured the muon flux and production rate of muon-induced neutrons at a depth of 611 m water equivalent. Our apparatus comprises three layers of crossed plastic scintillator hodoscopes for tracking the incident cosmic-ray muons and 760 L of gadolinium-doped liquid scintillator for producing and detecting neutrons. The vertical muon intensity was measured to be $I_μ = (5.7 \pm 0.6) \times 10^{-6}$ cm$^{-2}$s$^{-1}$sr$^{-1}$. The yield of muon-induced neutrons in the liquid scintillator was determined to be $Y_{n} = (1.19 \pm 0.08 (stat) \pm 0.21 (syst)) \times 10^{-4}$ neutrons/($μ\cdot$g$\cdot$cm$^{-2}$). A fit to the recently measured neutron yields at different depths gave a mean muon energy dependence of $\left\langle E_μ \right\rangle^{0.76 \pm 0.03}$ for liquid-scintillator targets.

description: Με βάση τις Στατιστικές Θνησιμότητας στην Κύπρο, από το 2004 μέχρι και το 2013, υπήρξαν 155 θάνατοι από αυτοκτονία ατόμων ηλικίας 35-64. Ενώ σύμφωνα με το Αρχείο Αιτιών Θανάτου της Μονάδας Παρακολούθησης Υγείας του Υπουργείου Υγείας καταγράφηκαν συνολικά 560 αυτοκτονίες. Αυτό υπονοεί ότι από το 2013 μέχρι και το 2020 υπήρξαν 405 αυτοκτονίες – 2,5 φορές περισσότερες σε 2/3 του αρχικού χρονικού διαστήματος. Τα περιστατικά δηλητηριάσεων έχουν εκτεταμένες συνέπειες, όχι μόνο στη σωματική υγεία αλλά και στην ψυχική ευεξία. Αυτή η εργασία έχει ως στόχο τη διερεύνηση της περίπλοκης σχέσης των σκόπιμων δηλητηριάσεων και των ψυχιατρικών διαστάσεων που μπορεί να κρύβονται πίσω τους. Οι ψυχιατρικές διαστάσεις που άπτονται τη δηλητηρίαση μπορεί να αφορούν την σκόπιμη αυτοδηλητηρίαση, που έχει σκοπό είτε τον αυτοτραυματισμό είτε την αυτοκτονία, την σκόπιμη δηλητηρίαση άλλου ατόμου και την πρόκληση ψυχιατρικών συμπτωμάτων ως συνέπεια της δηλητηρίασης. Η συγκεκριμένη εργασία θα επικεντρωθεί κυρίως στο να διερευνήσει το προφίλ των ατόμων που χρησιμοποιούν την αυτοδηλητηρίαση ως μέσω αυτοτραυματισμού ή αυτοκτονίας, τα κίνητρα, τους ψυχολογικούς και κοινωνικούς παράγοντες που μπορεί να οδηγήσουν σε τέτοια πράξη και τι μέτρα πρέπει να ληφθούν ούτως ώστε να προληφθεί.
description: Based on Mortality Statistics in Cyprus from 2004 to 2013, there were 155 suicides among individuals aged 35-64. While according to the Death Cause Registry of the Health Monitoring Unit of the Ministry of Health, a total of 560 suicides were recorded. This implies that from 2013 to 2020, there were 405 suicides – 2.5 times more in 2/3 of the initial time period. Poisoning incidents have extensive consequences, not only on physical health but also on mental well-being. This study aims to investigate the complex relationship between deliberate poisonings and the psychiatric dimensions that may be hidden behind them. Psychiatric dimensions related to poisoning may involve deliberate self-poisoning, which aims at either self-harm or suicide, deliberate poisoning of another person, and the provocation of psychiatric symptoms as a result of poisoning. This particular study will mainly focus on exploring the profile of individuals who use self-poisoning as a means of self-harm or suicide, the motives, the psychological and social factors that may lead to such acts, and what measures should be taken to prevent them.
