description: SHARE with CHARM program (SHAREv3) implements the statistical hadronization model description of particle production in relativistic heavy-ion collisions. Given a set of statistical parameters, SHAREv3 program evaluates yields and therefore also ratios, and furthermore, statistical particle abundance fluctuations. The physical bulk properties of the particle source is evaluated based on all hadrons produced, including the fitted yields. The bulk properties can be prescribed as a fit input complementing and/or replacing the statistical parameters. The modifications and improvements in the SHARE suite of programs are oriented towards recent and forthcoming LHC hadron production results including charm hadrons. This SHAREv3 release incorporates all features seen previously in SHAREv1.x and v2.x and, beyond, we include a complete treatment of charm hadrons and their decays, which further cascade and feed lighter hadron yields. This article is a complete and self-contained manual explaining and introducing both the conventional and the extended capabilities of SHARE with CHARM. We complement the particle list derived from the Particle Data Group tabulation composed of up, down, strange $u,d,s$ quarks (including resonances) with hadrons containing charm $c,\bar c$ quarks. We provide a table of the charm hadron decays including partial widths. The branching ratios of each charm hadron decays add to unity, which is achieved by including some charm hadron decay channels based on theoretical consideration in the absence of direct experimental information. A very successful interpretation of all available LHC results has been already obtained using this program.

Using the CMB angular power spectrum to study Dark Matter-photon interactions

description: In this paper, we explore the impact of Dark Matter-photon interactions on the CMB angular power spectrum. Using the one-year data release of the Planck satellite, we derive an upper bound on the Dark Matter-photon elastic scattering cross section of sigma_{DM-photon} < 8 x 10^{-31} (m_DM/GeV) cm^2 (68% CL) if the cross section is constant and a present-day value of sigma_{DM-photon} < 6 x 10^{-40} (m_DM/GeV) cm^2 (68% CL) if it scales as the temperature squared. For such a limiting cross section, both the B-modes and the TT angular power spectrum are suppressed with respect to LCDM predictions for l > 500 and l > 3000 respectively, indicating that forthcoming data from CMB polarisation experiments and Planck could help to constrain and characterise the physics of the dark sector. This essentially initiates a new type of dark matter search that is independent of whether dark matter is annihilating, decaying or asymmetric. Thus, any CMB experiment with the ability to measure the temperature and/or polarisation power spectra at high l should be able to investigate the potential interactions of dark matter and contribute to our fundamental understanding of its nature.

description: The Next Generation Science Standards (NGSS) require teachers to understand aspects of energy degradation and the second law of thermodynamics, including energy's availability and usefulness, changes in energy concentration, and the tendency of energy to spread uniformly. In an effort to develop learning goals that support teachers in building robust understandings of energy from their existing knowledge, we studied teachers' impromptu conversations about these topics during professional development courses about energy. Many of these teachers' ideas appear to align with statements from the NGSS, including the intuition that energy can be present but inaccessible, that energy can change in its usefulness as it transforms within a system, and that energy can lose its usefulness as it disperses, often ending up as thermal energy. Some teachers' ideas about energy degradation go beyond what is articulated in the NGSS, including the idea that thermal energy can be useful in some situations and the idea that energy's usefulness depends on the objects included in a scenario. Based on these observations, we introduce learning goals for energy degradation and the second law of thermodynamics that (1) represent a sophisticated physics understanding of these concepts, (2) originate in ideas that teachers already use, and (3) align with the NGSS.

description: The word IoT is quite common and the use such devices also normal nowadays. For example, if you visit a park at early morning you can observe many of them jogging, walking and doing their exercises. It happens as usual. But if you observe them keenly you can see them wearing wrist bands, step counters, calorie burn counter etc. The use of IoT devices in exercises is increasing and it is become common among the people. Similarly in Multi Speciality Hospitals, the patients are monitored 24/7 with the help of IoT devices like heart rate counter etc. The use of these devices in Hospitals and in medical field are slightly increasing day-by-day. The doctors personally suggest the use of IoT devices to some for monitoring the conditions of such patients. During the lockdowns due to the spread of Covid, it become a major concern about how to visit the doctor personally. So they needed the help of IoT. It is a time saving and cost efficient strategy. Yet the devices may be somewhat a little bit of costly but it will definitely very helpful in now and in future. Let us analyse the use of IoT in our society’s Health Care.

description: Triple threat processes and/or other forcings can lead to changes in the ocean happening fast and abruptly. These changes, referred to as “tipping points”, are critical thresholds in a marine system that, when exceeded, can lead to a significant change in the state of the system, which often can be irreversible. This presentation has been prepared with the financial support of Norges forskningsråd (Research Council of Norway) (309382) and the European Union’s Horizon 2020 research and innovation programme under grant agreement No 820989 (project COMFORT, Our common future ocean in the Earth system – quantifying coupled cycles of carbon, oxygen, and nutrients for determining and achieving safe operating spaces with respect to tipping points).

description: We address the interpretation of the Landau gauge gluon propagator at finite temperature as a massive type bosonic propagator. Using pure gauge SU(3) lattice simulations at a fixed lattice volume $\sim(6.5fm)^3$, we compute the electric and magnetic form factors, extract a gluon mass from Yukawa-like fits, and study its temperature dependence. This is relevant both for the Debye screening at high temperature $T$ and for confinement at low $T$.

description: We had previously defined the rho invariant $ρ_{spin}(Y,E,H, g)$ for the twisted Dirac operator $\not\partial^E_H$ on a closed odd dimensional Riemannian spin manifold $(Y, g)$, acting on sections of a flat hermitian vector bundle $E$ over $Y$, where $H = \sum i^{j+1} H_{2j+1} $ is an odd-degree differential form on $Y$ and $H_{2j+1}$ is a real-valued differential form of degree ${2j+1}$. Here we show that it is a conformal invariant of the pair $(H, g)$. In this paper we express the defect integer $ρ_{spin}(Y,E,H, g) - ρ_{spin}(Y,E, g)$ in terms of spectral flows and prove that $ρ_{spin}(Y,E,H, g)\in \mathbb Q$, whenever $g$ is a Riemannian metric of positive scalar curvature. In addition, if the maximal Baum-Connes conjecture holds for $π_1(Y)$ (which is assumed to be torsion-free), then we show that $ρ_{spin}(Y,E,H, rg) =0$ for all $r\gg 0$, significantly generalizing our earlier results. These results are proved using the Bismut-Weitzenböck formula, a scaling trick, the technique of noncommutative spectral sections, and the Higson-Roe approach.

How do social media and networks change the communication of scientists and citizens? What steps do archaeologists need to go, who want to use the new possibilities?
Perturbative non-Fermi liquids from dimensional regularization

description: We devise a dimensional regularization scheme for quantum field theories with Fermi surface to study scaling behaviour of non-Fermi liquid states in a controlled approximation. Starting from a Fermi surface in two space dimensions, the co-dimension of Fermi surface is extended to a general value while the dimension of Fermi surface is fixed. When Fermi surface is coupled with a critical boson centered at zero momentum, the interaction becomes marginal at a critical space dimension d_c=5/2. A deviation from the critical dimension is used as a small parameter for a systematic expansion. We apply this method to the theory where two patches of Fermi surface is coupled with a critical boson, and show that the Ising-nematic critical point is described by a stable non-Fermi liquid state slightly below the critical dimension. Critical exponents are computed upto the two-loop order.

description: Improvements both in the photonic confinement and in the emitter design have led to a steady increase in the strength of the light-matter coupling in cavity quantum electrodynamics experiments. This has allowed to access interaction-dominated regimes in which the state of the system can only be described in terms of mixed light-matter excitations. Here we show that, when the coupling between light and matter becomes strong enough, this picture breaks down, and light and matter degrees of freedom totally decouple. A striking consequence of such a counter-intuitive phenomenon is that the Purcell effect is reversed and the spontaneous emission rate, usually thought to increase with the light-matter coupling strength, plummets instead for large enough couplings.

description: The aim of the paper is to describe the development process of a multi-component m Health intervention to prevent unhealthy weight gain and psychosocial problems in psychosocially burdened (expectant) parents during pregnancy and postpartum. The development process occurred on two levels. First, we conducted focus groups with potential users and health professionals following a user-centered-design and participative approach. Second, we implemented behavior change techniques (BCT) based on the BCT Taxonomy (Michie et al., 2013) and cognitive-behavioral strategies within the intervention that are relevant for the psychosocially burdened individuals in this period of life. The findings of this paper contribute to a better understanding of the requirements and needs of psychosocially burdened individuals towards digital approaches to mental health promotion.

description: We fabricate and experimentally characterize a $H0$ photonic crystal slab nanocavity with a design optimized for maximal quality factor, $Q = 1.7$ million. The cavity, fabricated from a silicon slab, has a resonant mode at $λ= 1.59 \mathrm{μm}$ and a measured $Q$-factor of $400,000$. It displays nonlinear effects, including high-contrast optical bistability, at a threshold power among the lowest ever reported for a silicon device. With a theoretical modal volume as small as $V = 0.34(λ/n)^3$, this cavity ranks among those with the highest $Q/V$ ratios ever demonstrated, while having a small footprint suited for integration in photonic circuits.

description: We present Hubble Space Telescope (HST) and ground-based optical and near-infrared observations of SN 2005hk and SN 2008A, typical members of the Type Iax class of supernovae (SNe). Here we focus on late-time observations, where these objects deviate most dramatically from all other SN types. Instead of the dominant nebular emission lines that are observed in other SNe at late phases, spectra of SNe 2005hk and 2008A show lines of Fe II, Ca II, and Fe I more than a year past maximum light, along with narrow [Fe II] and [Ca II] emission. We use spectral features to constrain the temperature and density of the ejecta, and find high densities at late times, with n_e >~ 10^9 cm^-3. Such high densities should yield enhanced cooling of the ejecta, making these objects good candidates to observe the expected "infrared catastrophe," a generic feature of SN Ia models. However, our HST photometry of SN 2008A does not match the predictions of an infrared catastrophe. Moreover, our HST observations rule out a "complete deflagration" that fully disrupts the white dwarf for these peculiar SNe, showing no evidence for unburned material at late times. Deflagration explosion models that leave behind a bound remnant can match some of the observed properties of SNe Iax, but no published model is consistent with all of our observations of SNe 2005hk and 2008A.

title: Geweih! – Geweiht? Deponierungen von Hirschgeweihen und Hirschdarstellungen in Brunnen und Schächten der vorrömischen Eisenzeit Mitteleuropas
Creators: name: Fath, Barbara
Publisher: name: University Library Heidelberg
Year: 2013

description: Bilddarstellungen sind in der Vorgeschichte im Allgemeinen sehr selten, wenige Motive treten jedoch immer wiederin Erscheinung. Zu diesen gehört auch der Hirsch. Latènezeitliche Brunnen- und Schachtdeponierungen zeigen, dass der Hirsch in diesem Kontext eine prominente Rolle innehat. Als figürliche Darstellung auf deponierten Gefäßen, als Plastik, aber auch als Deponierung von schädelechten Geweihen oder Niederlegungen ganzer Tiere, wird der Hirsch hier dargestellt und mit Hilfe dieser Medien bildlich wie dinglich inszeniert.
Im Gegensatz zu anthropomorphen Bildwerken, die anhand von Inschriften in Mitteleuropa in der Latènezeit erstmals bestimmten Göttern zugewiesen werden können, lässt sich die Bedeutung zoomorpher Darstellungen nur schwer erschließen. Dennoch sprechen verschiedene Merkmale sowohl des Bildwerk selbst als auch seines Kontexts dafür, dass es sich speziell bei den latènezeitlichen Hirschdarstellungen um die Epiphanie einer Gottheit handelt, deren Erscheinungsbild sich im Laufe der Zeit von einer rein zoomorphen Vorstellung zu einer Mischform aus Hirsch und Mensch wandelt. Befunde aus römischer Zeit zeigen in Form von Geweihdeponierungen in (Brunnen-) schächten strukturelle Parallelen zwischen latènezeitlichen und römischen Befunden.
description: Generally image representations are rare in prehistoric times but a few subjects appear regularly. The deer is also among. La Tène period pit deposits show that the deer has a prominent role in this context. The deer is represented as a figural illustration on deposited vessels, as sculpture, but also as deposit of antlers or animals, therefore represented in a pictorially and materially form.
In contrast to anthropomorphic sculptures, which can be categorized on the basis of inscriptions in roman times to certain gods, the importance of zoomorphic representations can difficultly be inferred. Nevertheless some features, both the sculpture itself and its context, suggest that it is specifically for the La Tène deer representations to be the epiphany of a divinity, which appearance transforms itself from a zoomorphic idea to a hybrid of man and deer. Findings from the roman period show in form of antlers deposit in pits parallels between features of La Tène and roman period.

description: The success of the neutrino mechanism of core-collapse supernovae relies on the supporting action of two hydrodynamic instabilities: neutrino-driven convection and the Standing Accretion Shock Instability (SASI). Depending on the structure of the stellar progenitor, each of these instabilities can dominate the evolution of the gain region prior to the onset of explosion, with implications for the ensuing asymmetries. Here we examine the flow dynamics in the neighborhood of explosion by means of parametric two-dimensional, time-dependent hydrodynamic simulations for which the linear stability properties are well understood. We find that systems for which the convection parameter is sub-critical (SASI-dominated) develop explosions once large-scale, high-entropy bubbles are able to survive for several SASI oscillation cycles. These long-lived structures are seeded by the SASI during shock expansions. Finite-amplitude initial perturbations do not alter this outcome qualitatively, though they can lead to significant differences in explosion times. Supercritical systems (convection-dominated) also explode by developing large-scale bubbles, though the formation of these structures is due to buoyant activity. Non-exploding systems achieve a quasi-steady state in which the time-averaged flow adjusts itself to be convectively sub-critical. We characterize the turbulent flow using a spherical Fourier-Bessel decomposition, identifying the relevant scalings and connecting temporal and spatial components. Finally, we verify the applicability of these principles on the general relativistic, radiation-hydrodynamic simulations of Mueller, Janka, & Heger (2012), and discuss implications for the three-dimensional case.

Tomographic causal analysis of two-qubit states and tomographic discord

description: We study a behavior of two-qubit states subject to tomographic measurement. We propose a novel approach to definition of asymmetry in quantum bipartite state based on its tomographic Shannon entropies. We consider two types of measurement bases: the first is one that diagonalizes density matrices of subsystems and is used in a definition of tomographic discord, and the second is one that maximizes Shannon mutual information and relates to symmetrical form quantum discord. We show how these approaches relate to each other and then implement them to the different classes of two-qubit states. Consequently, new subclasses of X-states are revealed.

A first-principles study of structural and elastic properties of bulk SrRuO$_3$

description: We present a first-principles investigation of structural and elastic properties of experimentally observed phases of bulk SrRuO$_3$ - namely orthorhombic, tetragonal, and cubic - by applying density functional theory (DFT) approximations. At first, we focus our attention on the accuracy of calculated lattice constants in order to find out DFT approaches that best represent the crystalline structure of SrRuO$_3$, since many important physical quantities crucially depend on change in volume. Next, we evaluate single-crystal elastic constants, mechanical stability, and macroscopic elastic parameters trying to at least partially compensate for the existing lack of information about these fundamental features of SrRuO$_3$. Finally, we analyze the anomalous behavior of low-temperature orthorhombic phase under $C_{44}$ related shear deformation. It turns out that at critical strain values the system exhibits a distinct deviation from the initial behavior which results in an isosymmetric phase transition. Moreover, under $C_{44}$ related shear deformation tetragonal SrRuO3 becomes mechanically unstable raising an open question of what makes it experimentally observable at high temperatures.

description: We quantify the strength of the waves and their impact on the energy cascade in rotating turbulence by studying the wave number and frequency energy spectrum, and the time correlation functions of individual Fourier modes in numerical simulations in three dimensions in periodic boxes. From the spectrum, we find that a significant fraction of the energy is concentrated in modes with wave frequency $ω\approx 0$, even when the external forcing injects no energy directly into these modes. However, for modes for which the period of the inertial waves $τ_ω$ is faster than the turnover time $τ_\textrm{NL}$, a significant fraction of the remaining energy is concentrated in the modes that satisfy the dispersion relation of the waves. No evidence of accumulation of energy in the modes with $τ_ω= τ_\textrm{NL}$ is observed, unlike what critical balance arguments predict. From the time correlation functions, we find that for modes with $τ_ω< τ_\textrm{sw}$ (with $τ_\textrm{sw}$ the sweeping time) the dominant decorrelation time is the wave period, and that these modes also show a slower modulation on the timescale $τ_\textrm{NL}$ as assumed in wave turbulence theories. The rest of the modes are decorrelated with the sweeping time, including the very energetic modes modes with $ω\approx 0$.

Im vorliegenden Beitrag wird am Beispiel des Bundeslandes Mecklenburg-Vorpommern anhand ausgrabungstypischer Eingriffsfälle die mögliche Kollision der artenschutzrechtlichen Vorgaben mit den Interessen der archäologischen Denkmalpflege dargestellt. Abschließend werden einfache Möglichkeiten einer rechtkonformen Gestaltung von Ausgrabungen aufgezeigt.
description: Since the date of entry into force of the Federal Nature Conservation Act on 1st of March 2010 the specifications of the species protection law have changed significantly. From now on the comprehensive regulations for the species protection law, which are valid nationwide, and which are designed as principles not allowing any deviations, also have an impact on the archeological fieldwork. Taking the federal state of Mecklenburg- Vorpommern as an example for typical impacts of archaeological excavations, the possible conflicting points of view on both sides, the regulations concerning species protection law and the interests of the archaeological heritage conservation, will be demonstrated in this report. Finally, a simple way of how to conduct excavations complying with the species protection law will be demonstrated.

description: We evaluate the two-point function for the electromagnetic field tensor in $(D+1)$-dimensional de Sitter spacetime assuming that the field is prepared in Bunch-Davies vacuum state. This two-point function is used for the investigation of the vacuum expectation values (VEVs) of the field squared and the energy-momentum tensor in the presence of a conducting plate. The VEVs are decomposed into the boundary-free and plate-induced parts. For the latter, closed form analytical expressions are given in terms of the hypergeometric function. For $3\leqslant D\leqslant 8$ the plate-induced part in the VEV of the electric field squared is positive everywhere, whereas for $D\geqslant 9$ it is positive near the plate and negative at large distances. The VEV of the energy-momentum tensor, in addition to the diagonal components, contains an off-diagonal component which corresponds to the energy flux along the direction normal to the plate. Simple asymptotic expressions are provided at small and large distances from the plate compared with the de Sitter curvature scale. For $D\geqslant 4$, all the diagonal components of the plate-induced vacuum energy-momentum tensor are negative and the energy flux is directed from the plate.

description: Knochen können auch dann noch „sprechen“, wenn sie verbrannt sind. Leichenbrand ist eines der wichtigsten Quellenmaterialien für die historisch- archäologische Forschung und kann, wie dieser Beitrag darlegt, nicht nur biologische Daten liefern, sondern auch Informationen zu kulturhistorischen Fragestellungen. Die anthropologischen Grundlagen der Leichenbrandbearbeitung
werden kurz dargestellt, um zum einen deutlich zu machen, welches Potenzial im anthropologisch-archäologischen Quellenmaterial Leichenbrand über die biologischen Grunddaten hinaus verborgen ist. Zum anderen wird erkennbar, dass bereits die Erhebung der Daten von der Fragestellung abhängt und deshalb Leichenbrand nur dann „sprechen“ kann, wenn er in interdisziplinärer Zusammenarbeit zwischen Anthropologie und Archäologie analysiert wird. Am Beispiel des bronzezeitlichen Urnengräberfeldes Cottbus Alvensleben-Kaserne
(Brandenburg) wird die interdisziplinäre methodische Herangehensweise beschrieben und die dadurch ermöglichte Rekonstruktion von Funeralpraktiken diskutiert. Auf der Basis dieser Rekonstruktion der verschiedenen rituellen Handlungen wird interpretiert, wie soziale Identitäten im Bestattungsritual dargestellt und transformiert werden.
description: Cremation remains talk about the treatment of the dead – The interdisciplinary reconstruction of ritual action: An example from an urnfi eld of the Lusatian Culture Bones “speak” – even when they are burned. Cremation remains are one of the major source materials for archaeological research; moreover, as this paper explains, they do not only yield biological data but also provide us with information for particular historical questions. An overview of the essentials of the anthropological examination of cremation remains displays that there is considerable potential inherent in this source material beyond biological data. Furthermore, it becomes clear that already the collection of data relies upon the research questions that are asked; thus, cremation remains only do “speak” if they are analysed in interdisciplinary cooperation between anthropology and archaeology. Using the Bronze Age urnfi eld from Cottbus Alvensleben-Kaserne (Brandenburg, Germany) as a starting point the interdisciplinary approach is explicated, which allows the detailed reconstruction of funeral practices. This reconstruction of the sequence of ritual actions fi nally serves as the basis for interpreting how social identities are presented and transformed in burial ritual.

description: Das Gräberfeld von Schwetzingen (Baden-Württemberg) ist mit 203 identifi zierbaren Gräbern eine der größten bekannten Nekropolen der frühneolithischen Linearbandkeramik. Es befand sich südlich der Neckarmündung am Rande der Rheinebene. Im Großen und Ganzen weist Schwetzingen die Merkmale bekannter Nekropolen dieser Kultur auf: Die Toten legte man weitgehend in linker Hockerlage in NO-SW-orientierten engen Grabgruben nieder. Ungefähr der Hälfte der Bestatteten wurden Beigaben in Form von Keramikgefäßen, Geräten aus Felsgestein, Silex, Knochen und Geweih sowie Schmuck mitgegeben. Die unterschiedlichen Verzierungsmotive der Keramik legen eine Datierung in die jüngere Linearbandkeramik, in die Zeit um 5200/5000 v. Chr., nahe.
Neben den knapp 200 Körpergräbern beinhaltet das Gräberfeld auch eine Reihe von Brandbestattungen und so genannten Leergräbern. Eine vollständige anthropologische Auswertung fand bisher nicht statt, grundlegende Arbeiten wurden aber bereits durchgeführt. Damit werden erste vorläufi ge Aussagen zur Alter- und Geschlechtszusammensetzung möglich. Die Zahl der Frauen innerhalb der Population übersteigt die der Männer, während eine auffällig große Zahl an Kindern zu verzeichnen ist. Im Übrigen ist das Gräberfeld in seiner Zusammensetzung mit anderen Fundstellen dieser Periode vergleichbar.
description: The cemetery of Schwetzingen (Baden-Württemberg) is with its 203 remaining graves one of the largest known necropolises of the early Neolithic Linear Bandceramic culture (LBK). It was located south of the mouth of the Neckar into the Rhine, at the edge of the Rhine valley. On the whole Schwetzingen shows the characteristics of the known cemeteries of this culture. The dead were mostly
laid down on left side in a fl exed position in NE-SW-orientated, narrow grave pits. Approximately 50 % of the dead were buried with grave gifts such as pottery and tools out of stone, silex, bone and antler and trinket. The fi ndings in the grave, especially the ceramics’ varying ornamentation, suggest a dating around 5200/5000 BC.
Beside nearly 200 body burials some cremated remains and some so called empty graves were found at the cemetery. A complete anthropological analysis hasn´t been carried out but fundamental informations exist. Based on these results some preliminary statements concerning the composition of age and gender are possible. Within the population the women exceed the men while a large number of children is recorded. As for the rest the momentary anthropological results of the cemetery are comparable with other sites of this period.

description: Der von einigen Autoren postulierte „mesolithische Ackerbau“ stützt sich lediglich auf einzelne Pollenkörner vom Getreide-Typ in Pollendiagrammen. Es wird erneut gezeigt, dass es keine sicher Abgrenzung zwischen Pollen vom Getreide-Typ und
einigen Wildgräsern gibt und dass derartige Typen vereinzelt bereits seit dem Spätglazial auftreten. Während zahlreiche neolithische Fundstellen große Mengen an makroskopischen Kulturpfl anzenresten lieferten, fehlen diese aus dem Mesolithikum völlig. Ohne sicher datierte Makroreste von Kulturpfl anzen ist ein mesolithischer Ackerbau nicht nachweisbar.
description: The “Mesolithic agriculture” as assumed by several authors, is based solely on single pre-Neolithic pollen grains of the Cerealiatype that occur in pollen diagrams. It is shown that absolute distinction of pollen from wild grasses and cereals is impossible and single pollen grains of this type are known already from the Late-glacial onwards. While numerous excavations of Neolithic sites have produced large numbers of macro-remains from cultivated plants, they are completely lacking in Mesolithic sites. Without well-dated macro-remains of crop plants there is no evidence of Mesolithic agriculture.

description: Der Abbau von Hornstein in Kleinkems kann in die Zeit um 4050 - 4250 v. Chr. datiert werden. Das aufwendig gewonnene und schlagtechnisch gut geeignete Kleinkemser Rohmaterial ist jedoch im Gegensatz zu Silices anderer nahegelegener Abbaustellen nur wenig verbreitet. Es werden Beobachtungen beschrieben, die eine erschwerte makroskopische Identifizierung von Kleinkemser Hornstein verursachen können. Hitzeeinwirkungen verändern die Knollen, sie verursachen eine andere Färbung und eine zusätzliche Zonierung. Kleinkemser Hornstein patiniert unter Humuseinfluss und erhält eine bräunliche Oberfläche, die makroskopisch nicht mehr an den bergfrischen, weißen bis hellgrauen Hornstein erinnert.
description: The prehistoric mining of chert at Kleinkems can be dated to around 4250 – 4050 BC. The extraction was a complex process and, although the knapping quality of the raw material from Kleinkems is good, its distribution is limited compared with that of siliceous rocks from other nearby sources. Certain observations have been described that could perhaps make a macroscopic identification of the chert from Kleinkems more difficult. The effect of heat on the nodules is to change their colour and increase the banding. Humus gives Kleinkems chert a patina with a brownish surface that, macroscopically, no longer resembles that of freshly mined white or pale grey chert.

description: We investigate the consequences of space-time being curved on space-based quantum communication protocols. We analyze tasks that require either the exchange of single photons in a certain entanglement distribution protocol or beams of light in a continuous-variable quantum key distribution scheme. We find that gravity affects the propagation of photons, therefore adding additional noise to the channel for the transmission of information. The effects could be measured with current technology.
