title: Ideology and Symbolism of Traditional Architecture
Creators: name: Vasa, Ditamulu
Publisher: name: Journal of Neolithic Archaeology

description: The social and cultural memories existing in the Naga oral histories relating to megalithic culture elucidates important information on the ideology of erecting megalithic monuments, social organization, rituals and their economic usages. The well-defined cultural values of erecting megalithic monuments also appear to have a relationship with craft specialization to the point of perpetuating the memory of a person who has gained a higher status. This paper discusses briefly the Feast of Merit that coincides with the stone dragging ceremony and the status men earn in terms of representations adorning their houses in the Chozuba and Runguzu villages of the Chakhesang tribe.

description: A special configuration of graph state stabilizers, which contains only Pauli $σ_X$ operators, is studied. The vertex sets $ξ$ associated with such configurations are defined as what we call X-chains of graph states. The X-chains of a general graph state can be determined efficiently. They form a group structure such that one can obtain the explicit representation of graph states in the X-basis via the so-called X-chain factorization diagram. We show that graph states with different X-chain groups can have different probability distributions of X-measurement outcomes, which allows one to distinguish certain graph states with X-measurements. We provide an approach to find the Schmidt decomposition of graph states in the X-basis. The existence of X-chains in a subsystem facilitates error correction in the entanglement localization of graph states. In all of these applications, the difficulty of the task decreases with increasing number of X-chains. Furthermore, we show that the overlap of two graph states can be efficiently determined via X-chains, while its computational complexity with other known methods increases exponentially.

description: The use of ethnographic analogies for the construction of explanatory patterns and scientific narratives has a long history within archaeological research. While appropriate critique was raised with regard to the way analogies were used, the rise of critical perspectives within recent archaeological debates and discourses clearly highlights the need for a critical and reflective use of comparative analyses which will help us to go beyond a perception of archaeology as a cultural-historical science. The diversity and variability of the meaning of monumentality and megalith building in modern-day India shows the potential of such an approach and the importance of the integration of the perspectives of local communities without a direct link to scientific discourses. Monumentality and megalithic construction, due to the complexity and variance of this specific phenomenon, constitute a good example for the potential benefit and gain of the integration of comparative, ethnoarchaeological perspectives.

description: Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large asteroids have been disrupted by impacts over the age of the Solar System, producing groups of fragments known as asteroid families. Here we explain how the asteroid families are identified, review their current inventory, and discuss how they can be used to get insights into long-term dynamics of main belt asteroids. Electronic tables of the membership for 122 notable families are reported on the Planetary Data System node.

description: A new method of regime shift detection in the correlation coefficient is proposed. The method is designed to find multiple change-points with unknown locations in time series. It signals a possible regime shift in real time and allows for its monitoring. The method is tested on randomly generated time series with predefined change-points. It is applied to examine structural changes in the Bering Sea climate. A major shift is found in 1967, which coincides with a transition from a zonal type of atmospheric circulation to a meridional one. The roles of the Siberian and Alaskan centers of action on winter temperatures in the eastern Bering Sea have been investigated.

description: The theory of sparse structures usually uses tree like structures as building blocks. In the context of sparse/dense dichotomy this role is played by graphs with bounded tree depth. In this paper we survey results related to this concept and particularly explain how these graphs are used to decompose and construct more complex graphs and structures. In more technical terms we survey some of the properties and applications of low tree depth decomposition of graphs.
Energy conditions in the epoch of galaxy formation

description: The energy conditions of Einstein gravity (classical general relativity) do not require one to fix a specific equation of state. In a Friedmann-Robertson-Walker universe where the equation of state for the cosmological fluid is uncertain, the energy conditions provide simple, model-independent, and robust bounds on the behaviour of the density and look-back time as a function of red-shift. Current observations suggest that the "strong energy condition" is violated sometime between the epoch of galaxy formation and the present. This implies that no possible combination of "normal" matter is capable of fitting the observational data.

title: New Discoveries of Petroglyphs in Vangchhia
Creators: name: Singh, Salam Shyam
Publisher: name: Journal of Neolithic Archaeology
Year: 2019

description: Vangchhia is a small village in Mizoram, lying on the Indo-Myanmar border. Many engraved menhirs were discovered at Vangchhia during the course of exploration. Also, petroglyphs were found in four localities of this particular village. Though their number is very limited, they are very significant for study as they will reflect the cultural life of the people who carved these petroglyphs before the current inhabitants of the area arrived. In terms of subject matter, they are similar in style and theme to their engraved counterparts on the menhirs found in this village. These petroglyphs are made by applying the simple methods of engraving and carving on the exposed rock outcrops situated on the hill slopes overlooking the Tiau River, which flows about a kilometer to the east of the petroglyph sites. It is worth studying these petroglyphs to reconstruct the cultural history of Mizoram mainly before the introduction of Christianity in Mizoram, as the Mizos stopped the practice of engraving petroglyphs on the rock surfaces after their conversion to Christianity in the 19th century. So this work has been taken up for discussion. This paper will discuss the form, subject matter and distribution of the rock art sites in this village and the probable purpose of these petroglyphs.

description: In order to improve the precision of domain wall dynamics measurements, we develop a coplanar waveguide-based setup where the domain wall motion should be triggered by pulses of magnetic field. The latter are produced by the Oersted field of the waveguide as a current pulse travels toward its termination, where it is dissipated. Our objective is to eliminate a source of bias in domain wall speed estimation while optimizing the field amplitude. Here, we present implementations of this concept for magnetic force microscopy (MFM) and synchrotron-based investigation.
title: Megalithic Builders of Odisha

description: The state of Odisha is one of the most important regions for tribal groups and we find 62 major types of ethnic communities belonging to different language families. Although numbers of scholars have widely reported on different aspects of tribal religion, beliefs, practices and a few kinds of literature give some information about the living megalithic tradition, we do not have adequate data on their distribution pattern in this region. However, the present work is based on the recent work on the living megalithic tradition of Munda communities. Up to now, many papers have been published on the Mundas but no one has reflected on the living megalithic tradition. Finally, the paper, still at its preliminary stage, gives us some information about their distribution and some other information related to the funeral rituals and megalithic tradition.

description: In a previous note various methods of impacting birds on aircraft parts were discussed. It was concluded that while true simulation could be obtained by placing a stationary bird in the path of a rapidly moving aircraft part ("target"), this was technically difficult and costly. If the impact could be properly simulated by hurling a bird at a static target, this would be a far more convenient and economic method. The present note examines the relative merits of these two simulations, the so-called "sled" (moving target) and "gun" (moving bird) methods.

description: One of the fascinating properties of the new families of two-dimensional crystals is their high stretchability and the possibility to use external strain to manipulate, in a controlled manner, their optical and electronic properties. Strain engineering, understood as the field that study how the physical properties of materials can be tuned by controlling the elastic strain fields applied to it, has a perfect platform for its implementation in the atomically thin semiconducting materials. The object of this review is to give an overview of the recent progress to control the optical and electronics properties of 2D crystals, by means of strain engineering. We will concentrate on semiconducting layered materials, with especial emphasis in transition metal dichalcogenides (MoS$_2$, WS$_2$, MoSe$_2$ and WSe$_2$). The effect of strain in other atomically thin materials like black phosphorus, silicene, etc., is also considered. The benefits of strain engineering in 2D crystals for applications in nanoelectronics and optoelectronics will be revised, and the open problems in the field will be discussed.

description: To the Khasi-Pnar community, who are considered to be the authochthons of the Khasi-Jaintia hills of Meghalaya in northeastern India, the importance of their megalithic monuments is evident in their language itself, since the word “Kyn-maw” or “memory” derives from the word “Maw” or “stone.” The present paper deals with the general understanding of the megalithic monuments from these hills where the practice of erecting such monuments is a living tradition. The paper presents a summary of the functions and role of the megalithic monuments found in every nook and corner of the Khasi-Jaintia hills landscape and provides a close examination of the clan cists which are directly connected with the funerary practice of the people and their significance in the entire megalithic tradition.

description: The renormalizable coloron model is built around a minimally extended color gauge group, which is spontaneously broken to QCD. The formalism introduces massive color-octet vector bosons (colorons), as well as several new scalars and fermions associated with the symmetry breaking sector. In this paper, we examine vacuum stability and triviality conditions within the context of the renormalizable coloron model up to a cutoff energy scale of 100~TeV, by computing the beta-functions of all relevant couplings and determining their running behavior as a function of the renormalization scale. We constrain the parameter space of the theory for four separate scenarios based on differing fermionic content, and demonstrate that the vectorial scenarios are less constrained by vacuum stability and triviality bounds than the chiral scenarios. Our results are summarized in exclusion plots for the separate scenarios, with previous bounds on the model overlaid for comparison. We find that a 100 TeV hadron collider could explore the entire allowed parameter space of the chiral models very effectively.

description: The experimental conditions by which electromagnetic signals (EMS) of low frequency can be emitted by diluted aqueous solutions of some bacterial and viral DNAs are described. That the recorded EMS and nanostructures induced in water carry the DNA information (sequence) is shown by retrieval of that same DNA by classical PCR amplification using the TAQ polymerase, including both primers and nucleotides. Moreover, such a transduction process has also been observed in living human cells exposed to EMS irradiation. These experiments suggest that coherent long range molecular interaction must be at work in water so to allow the observed features. The quantum field theory analysis of the phenomenon is presented.

description: The end of the third millennium BCE represents (not only) on the Iberian Peninsula the time of transition to the Bronze Age. At the same time this is the time of a general climatic event, the so-called 4.2 ka BP event, which can be observed (in different manifestations) in different regions of the northern hemisphere. By synchronizing cultural and climatic developments and above all by assessing demographic developments and their spatial development, a much-discussed connection between the two phenomena can be made plausible and opens the perspective for further, more detailed research on the interdependence between cultural, demographic and climatological processes. For this purpose, the results of aoristics, 14C sum calibration and the evaluation of the concentration of long-chain n-alkane homologues of terrestrial origin as precipitation predictor are combined, their correlation is presented and possible responses are interpreted from the mapping of the settlement system development. This article provides an initial overview of the current results.

In this framework we discuss the brane Kantowski-Sachs cosmology and compare it with standard Kantowski-Sachs cosmology in Einstein theory for some specific matter choice. For several specific choice of relation between energy and pressure, the behavior of the scale factors at early time is found. It is shown that the brane Kantowski-Scahs cosmology may quickly become isotropic for some choices of matter. We also discuss the universe fate of Kantowski-Sachs cosmological model by means of the rip or singularity in both the theories.

Alteration of microbial metabolic activities in association with detritus.
Creators: name: Paerl, H.W.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1984

description: Detritus serves as a microhabitat, or microzone, hosting redox gradients, altered microbial metabolism and associated biochemical nutrient transformation processes qualitatively and quantitatively distinct from the ambient planktonic environment. Distributions of microbial communities and their extracellular deposition products on detrital as well as non-detrital submersed surfaces are patchy in nature, both in terms of physical distribution and associated metabolism. This patchiness promotes the development of steep redox gradients, which in turn lead to diverse microhabitats in which microorganisms, protozoans and invertebrates, all having narrow environmental tolerances, can reside. The compact nature of gradients helps promote diffusive exchange of metabolites, gases and nutrients, thereby maintaining community diversity and structural stability of microzones. Microzones also harbor specific nutrient transformation processes (nitrogen cycle N2 fixation, ammonification, nitrification and denitrification) which may otherwise be unfavorable or inhibited in ambient waters.

Extracting Type Values from Semistructured Databases

dynamic typing

description: To date, current investigations on Semi-Structured Data (SSD) have focused on query languages that operate directly on graph-based data by matching flexible path expressions against the graph-database topology. The problem with this approach is that it renounces in principle the benefits typically associated with typing information. In particular, storage and query optimisation techniques, representation of user-knowledge of the data, and validation of computations cannot be based upon static typing information. On the other hand, the various attempts to reintroduce types for SSD, while effectively returning some of the benefits of static typing, compromise the irregular nature of SSD databases, by allowing just for mild forms of irregularities. Our investigation is motivated by the observation that, despite the inherent irregularity of the structure, many or indeed most SSD databases contain one or more subsets that present a high degree of regularity and could therefore be treated as typed values of a programming language. In this thesis we lay the formal foundations underlying a novel query methodology based on an extraction system that, given an SSD database and a type of a target language, results in: (i) a subset of the database that is semantically equivalent to a value of the given type; (ii) a measure that informs the user about the quality of his type with respect to the original database. The extracted subset can then be converted into a value of that type and injected into the language environment, where it can be computed over with all the benefits of static typing.

description: In Bilyi Kamin, Ukraine, a Trypillia megasite of the Chechelnyk group west of the River Southern Buh was systematically investigated by high-resolution magnetometry, targeted excavations and radiometric dating. These new data make it possible to discuss afresh the significance of these large settlements and their relation to the already much longer intensively investigated megasites of the Southern Buh-Dnipro interfluve. The research confirmed that the settlement Bilyi Kamin had an extraordinary size of almost 100 ha and undoubtedly was of a carefully planned character. In order to realise a settlement of this size in the hilly landscape, enormous height differences within the settlement were accepted. Apparently, the intention to place three monumental integrative buildings on a promontory, widely visible from afar, played a decisive role. The study includes a detailed examination of the architecture and find materials of a dwelling. Compared to settlements of the Southern Buh-Dnipro interfluve, these investigations reveal, among other things, differences in waste disposal and similarities in architectural features. In the wider context, the newly obtained dating results from Bilyi Kamin seem to indicate that the peak of population concentration in Trypillia giant settlements in the region west of the River Southern Buh was already passed around 3800/3750 BCE. By contrast, this agglomeration process continued in the Southern Buh-Dnipro interfluve until about 3650 BCE. As possible reasons for these different trajectories differences in social organisation are taken into account.

description: The ability of uropathogenic Escherichia coli (UPEC) to cause urinary tract infections is dependent on their ability to colonize the uroepithelium. Infecting bacteria ascend the urethra to the bladder and then kidneys by attaching to the uroepithelial cells via the differential expression of adhesins. P pili are associated with pyelonephritis, the more severe infection of the kidneys. In order to find means to treat pyelonephritis, it is therefore of interest to investigate the properties P pili. The mechanical behavior of individual P pili of uropathogenic Escherichia coli has recently been investigated using optical tweezers. P pili, whose main part constitutes the PapA rod, composed of ~1000 PapA subunits in a helical arrangement, are distributed over the bacterial surface and mediate adhesion to host cells. We have earlier studied P pili regarding its stretching/elongation properties where we have found and characterized three different elongation regions, of which one constitute an unfolding of the quaternary (helical) structure of the PapA rod. It was shown that this unfolding takes place at an elongation independent force of 27 pN. We have also recently performed studies on its folding properties and shown that the unfolding/folding of the PapA rod is completely reversible. Here we present a study of the dynamical properties of the PapA rod. We show, among other things, that the unfolding force increases and that the folding force decreases with the speed of unfolding and folding respectively. Moreover, the PapA rod can be folded-unfolded a significant number of times without loosing its characteristics, a phenomenon that is believed to be important for the bacterium to keep close contact to the host tissue and consequently helps the bacterium to colonize the host tissue.

description: The Spherical Proportional Counter is a novel type of radiation detector, with a low energy threshold (typically below 100 eV) and good energy resolution. This detector is being developed by the network NEWS, which includes several applications. We can name between many others Dark Matter searches, low level radon and neutron counting or low energy neutrino detection from supernovas or nuclear reactors via neutrino-nucleus elastic scattering. In this context, this works will present the characterization of a spherical detector of 1 meter diameter using two argon-based mixtures (with methane and isobutane) and for gas pressures between 50 and 1250 mbar. In each case, the energy resolution shows its best value in a wide range of gains, limited by the ballistic effect at low gains and by ion-backflow at high gains. Moreover, the best energy resolution shows a degradation with pressure. These effects will be discussed in terms of gas avalanche properties. Finally, the effect of an electrical field corrector in the homogenity of the gain and the energy threshold measured in our setup will be also discussed.

description: The parent compound of an unconventional superconductor must contain unusual correlated electronic and magnetic properties of its own. In the high-Tc potassium intercalated FeSe, there has been significant debate regarding what the exact parent compound is. Our studies unambiguously show that the Fe-vacancy ordered K2Fe4Se5 is the magnetic, Mott insulating parent compound of the superconducting state. Non-superconducting K2Fe4Se5 becomes a superconductor after high temperature annealing, and the overall picture indicates that superconductivity in K2-xFe4+ySe5 originates from the Fe-vacancy order to disorder transition. Thus, the long pending question whether magnetic and superconducting state are competing or cooperating for cuprate superconductors may also apply to the Fe-chalcogenide superconductors. It is believed that the iron selenides and related compounds will provide essential information to understand the origin of superconductivity in the iron-based superconductors, and possibly to the superconducting cuprates.

description: La lesione da pressione è definita come “lesione localizzata alla cute e/o al tessuto sottostante solitamente localizzata su una prominenza ossea, come risultato della pressione o della pressione in combinazione con le forze di taglio” (EPUAP, 2019). Le stime di incidenza e prevalenza delle ulcere da pressione variano sia a seconda dei Paesi e contesti sanitari considerati, sia delle popolazioni osservate che dei metodi di raccolta dati utilizzati (O’Connor et al., 2021). In Italia il dato di prevalenza di LdP a livello domiciliare, sicuramente sottostimato, è del 24,8% (Bellingeri, 2002 citato da Bellingeri, 2020). Il crescente spostamento verso l'assistenza basata sulla comunità, indica la necessità che le persone a rischio di sviluppare lesioni da pressione siano maggiormente coinvolte nel processo di cura (O’Connor et al. 2019). L’Institute for Healthcare Improvement ha pubblicato nel 2018 un rapporto che tratta il tema dell’assistenza domiciliare e come la cura dei pazienti nelle loro case offra molti potenziali benefici. Tuttavia, nel report vengono analizzate le diverse tipologie di rischio che possono verificarsi al paziente trattato a casa, tra cui il rischio legato alla presenza di lesioni da pressione (IHI Report, 2018). Nell'ambito dell'assistenza domiciliare fondamentale è il coinvolgimento dei pazienti e degli informal caregiver, ovvero un familiare, un amico, un vicino di casa, un badante che si occupa di assistere nella quotidianità il paziente. Pertanto, l'informal caregiver diventa perno importante nella valutazione del rischio di ulcere da pressione, che richiede conoscenze e abilità adeguate e che necessitano di corrispondenti interventi educativi (O’Connor et al., 2019). Si evidenzia che, se si applicassero dei programmi educativi e informativi/formativi nei confronti dei caregiver informali sulla prevenzione delle LdP, si ridurrebbero o eliminerebbero notevolmente i fattori contribuenti l’insorgenza di ulcere da pressione (Alosi et al., 2012 citato da Kaur et al., 2018). Nell’ambito dell’assistenza domiciliare, l’uso di protocolli formativi ed educativi per la prevenzione e la gestione delle LdP, nei confronti dei caregiver informali, sono scarsi e quasi assenti. Pertanto, utile sarebbe continuare a porre l’attenzione in merito per evitare l'elevato rischio di insorgenza di LdP nei pazienti trattati a domicilio. Obiettivo dello studio: Ridurre le LdP nei pazienti a domicilio dovute ai comportamenti inadeguati degli informal caregivers. Quindi individuare informazioni relative ai fattori di rischio che possono verificarsi e concorrere allo sviluppo della LdP, correlati alle azioni svolte degli informal caregiver. Adottare misure dirette ed indirette di miglioramento per il personale sanitario e i caregiver informali.

description: During extensive field work, different aspects of the large Tripolye settlement Stolniceni I in northwest Moldova were investigated by an international team. These investigations allow a reassessment of these population agglomerations from the first half of the 4th millennium BCE in Moldova and their comparison with more eastern Tripolye sites. The investigations carried out in 2017 included the completion of the archaeo-magnetic survey of the settlement and the targeted archaeological excavations of various types of contexts. Besides the investigation of a ditch enclosing the site and test trenches in different parts of the settlement, the excavations focused mainly on two areas in the north of the settlement: On the one hand, excavations were carried out in a pottery production complex, including the uncovering of a pottery kiln, several pits and a dwelling. On the other hand, one specific ‘ash-mound-like’ anomaly was investigated which are arranged in regular intervals at the periphery of the settlement. The archaeological excavations were accompanied by comprehensive archaeobotanical analyses, which provide an insight into the subsistence and wood selection in the settlement, as well as permitting environmental reconstructions. A larger series of 14C-datings proves the occupation of the settlement Stolniceni I over a longer period between about 3925 and 3700 BCE.

title: Land-use and environmental history at the Middle Neolithic settlement site Oldenburg-Dannau LA 77

description: The ‘Oldenburger Graben’ is an extended wetland area in Northern Germany with a rich archaeological heritage. Several settlements from Late Mesolithic to Late Neolithic were found along the former shore in elevations under the recent sea-level. Environmental reconstructions around the Middle Neolithic settlement site Oldenburg-Dannau LA77 enabled for a detailed reconstruction of the sea level development and the according environmental transformations. The general increase from values of -4 m at around 5500 cal BC to -2.5 m at around 3000 cal BC is described as a process of stagnation and transgression with strong influence on living conditions in the lowland area. A lake- and peat-landscape was drowned by the rising sea level and underwent a transformation into a marine environment. By the time the coastal erosion resulted in a damming of the former bay and a brackish lagoon lake developed that succeeded towards a freshwater system. The Middle Neolithic settlement of Dannau LA 77could be linked to a brackish-marine transgression phase. From c. 3500 until 2900 cal BC the results indicate local settlement activities including cereal cultivation with a short phase of reduced activities at around c. 3200 cal BC. During this time of occupation, the sandy elevation was still connected to the mainland. After c. 2900 cal BC the site became an island, the time when the local inhabitation ceased. The comparison with other investigated sites in the Oldenburger Graben region shows a stepwise Neolithisation process with indications for single domestic animals occurring already in the Late Mesolithic and a transition to animal husbandry around 4100 cal BC, the beginning of the Early Neolithic (EN) Ia. Single Cereal-Type pollen grains also occur already during the Ertebølle-time but arable farming did not contribute substantially to the nutrition before c. 3800 cal BC, i.e. the EN Ib. Thus, the transformation of the subsistence economy was a stepwise process what supports the idea of an autochthonous Neolithisation process.

description: We report the alignment and shape of dark matter, stellar, and hot gas distributions in the EAGLE and cosmo-OWLS simulations. The combination of these state-of-the-art hydro-cosmological simulations enables us to span four orders of magnitude in halo mass ($11 < log_{10}(M_{200}/ [h^{-1}M_\odot]) < 15$), a wide radial range ($-2.3 < log_{10}(r/[h^{-1}Mpc ]) < 1.3$) and redshifts $0 < z < 1$. The shape parameters of the dark matter, stellar and hot gas distributions follow qualitatively similar trends: they become more aspherical (and triaxial) with increasing halo mass, radius and redshift. We measure the misalignment of the baryonic components (hot gas and stars) of galaxies with their host halo as a function of halo mass, radius, redshift, and galaxy type (centrals vs satellites and early- vs late-type). Overall, galaxies align well with the local distribution of the total (mostly dark) matter. However, the stellar distributions on galactic scales exhibit a median misalignment of about 45-50 degrees with respect to their host haloes. This misalignment is reduced to 25-30 degrees in the most massive haloes ($13 < log_{10}(M_{200}/ [h^{-1}M_\odot ]) < 15$). Half of the disc galaxies in the EAGLE simulations have a misalignment angle with respect to their host haloes larger than 40 degrees. We present fitting functions and tabulated values for the probability distribution of galaxy-halo misalignment to enable a straightforward inclusion of our results into models of galaxy formations based on purely collisionless N-body simulations.

Non-homogeneous analysis of rogue wave probability evolution over a shoal

description: Non-equilibrium evolution of wave fields, as occurring over sudden bathymetry variations, can produce rogue seas with anomalous wave statistics. We handle this process by modifying the Rayleigh distribution through the energetics of second-order theory and a non-homogeneous reformulation of the Khintchine theorem. The resulting probability model reproduces the enhanced tail of the probability distribution of unidirectional wave tank experiments. It also describes why the peak of rogue wave probability appears atop the shoal, and explains the influence of depth on variations in peak intensity. Furthermore, we interpret rogue wave likelihoods in finite depth through the-diagram, allowing a quick prediction for the effects of rapid depth change apart from the probability distribution.
