title: Eine neue Parallele zu den Einbauten im spätmichelsbergzeitlichen Erdwerk von Calden, Kr. Kassel?
Creators: name: Dirk Raetzel-Fabian
Publisher: name: Journal of Neolithic Archaeology
Year: 2003

description: The late Michelsberg enclosure of Calden, Kr. Kassel (Germany), is well known for its elaborate wooden gateways. Comparable structures with a more simple layout are up to this day only known from the Urmitz enclosure, which dates to an early Michelsberg phase. This article discusses a still undated ditch system near Großfahner, Kr. Erfurt, which shows very similar features. It might belong to the Baalberge culture, thus being contemporary with the Calden enclosure.

What Do We Mean When We Say “Presence”?

description: Characterizations of presence are many and various. The first part of this article applies philosophical and psychological lenses to three common descriptions: Presence as (or as following from) “the suspension of disbelief,” presence as the “illusion of nonmediation,” and presence as “(the feeling of) being there.” These construals of presence—the assumptions and commitments they make—are compared with one another, their plausibility and utility appraised. The second, shorter part of the article is not so much interested in definitions as distinctions that may help us ask better questions moving forward. We briefly consider the role of attention in presence, whether, when, or how presence is “binary,” and whether it is helpful to speak of presence in unmediated physical reality. A recurring theme throughout the article is whether a given understanding of presence (mis)construes the mind as monolithic: That is, as uniformly rational and consciously accessible. In closing, we suggest that researchers specify precisely what type of presence they’re referring to whenever the concept is evoked; and that states such as involvement, absorption, and engagement be kept conceptually separate from presence, since they speak to “higher” cognitive functioning than simply feeling self-located in virtual environments, and indeed need not presup-pose placeness or spatiality at all.

description: A rich variety of molecular species has now been observed towards hot cores in star forming regions and in the interstellar medium. An increasing body of evidence from millimetre interferometers suggests that many of these form at the interfaces between protostellar outflows and their natal molecular clouds. However, current models have remained unable to explain the origin of the observational bias towards wide-angled "brandy snifter" shaped outflows over narrower "champagne flute" shapes in carbon monoxide imaging. Furthermore, these wide-angled systems exhibit unusually high abundances of the molecular ion HCO$^+$. We present results from a chemo-dynamic model of such regions where a rich chemistry arises naturally as a result of turbulent mixing between cold, dense molecular gas and the hot, ionized outflow material. The injecta drives a rich and rapid ion-neutral chemistry in qualitative and quantitative agreement with the observations. The observational bias towards wide-angled outflows is explained naturally by the geometry-dependent ion injection rate causing rapid dissociation of CO in the younger systems.

Scatter broadening of compact radio sources by the ionized intergalactic medium: Prospects for detection with Space VLBI and the SKA

description: We investigate the feasibility of detecting and probing various components of the ionized intergalactic medium (IGM) and their turbulent properties at radio frequencies through observations of scatter broadening of compact sources. There is a strong case for conducting targeted observations to resolve scatter broadening (where the angular size scales as $\sim ν^{-2}$) of compact background sources intersected by foreground galaxy haloes and rich clusters of galaxies to probe the turbulence of the ionized gas in these objects, particularly using Space VLBI with baselines of 350,000 km at frequencies below 800 MHz. The sensitivity of the Square Kilometre Array (SKA) allows multifrequency surveys of interstellar scintillation (ISS) of $\sim 100 \,μ$Jy sources to detect or place very strong constraints on IGM scatter broadening down to $\sim 1\, μ$as scales at 5 GHz. Scatter broadening in the warm-hot component of the IGM with typical overdensities of $\sim 30$ cannot be detected, even with Space VLBI or ISS, and even if the outer scales of turbulence have an unlikely low value of $\sim 1$ kpc. Nonetheless, intergalatic scatter broadening can be of order $\sim 100\, μ$as at 1 GHz and $\sim 3\, μ$as at 5 GHz for outer scales $\sim 1$ kpc, assuming a sufficiently high source redshift that most sight-lines intersect within a virial radius of at least one galaxy halo ($z \gtrsim 0.5$ and $z \gtrsim 1.4$ for $10^{10} {\rm M}_\odot$ and $10^{11} {\rm M}_\odot$ systems, following McQuinn (2014)). Both Space VLBI and multiwavelength ISS observations with the SKA can easily test such a scenario, or place strong constraints on the outer scale of the turbulence in such regions.

title: Megaliths, Monuments, and Materiality
Creators: name: Darvill, Timothy
Publisher: name: Journal of Neolithic Archaeology
Year: 2010

description: Stones, and especially the arrangement of large stones in relation to one another, have long been the focus of attention in megalith studies, a concern reflected in the name itself. It is, however, a blinkered view. Many so-called megalithic monuments embody other carefully selected materials in their construction, including turf, soil, rubble, and timber. In considering long barrows, Paul Ashbee noted that it was a false distinction to separate earthen long barrows from stone-chambered long barrows as the builders of long barrows inevitably used materials available within their local environments. Alternatively, writing mainly about the Irish material, Arthur ApSimon suggested a development from timber to stone implying a chronological progression in the preferred use of materials. Whether environmental or evolutionary, it is certain that many monuments interchangeably combine stone and wood in their construction in a way that forces us to consider what these and other materials meant to the megalith builders. Was it simply about what was available? Or what was fashionable? Or were there deeper sets of meanings relating to how different materials were perceived and understood within the cosmological systems that lie behind the design, construction, and use of long barrows, passage graves, dolmens and other related monuments? Focusing upon wood and stone, it is argued here that both were components of a cyclical world view of life and death that was embedded in the fabric and structure of monuments.

description: IRIS data allow us to study the solar transition region (TR) with an unprecedented spatial resolution of 0.33 arcsec. On 2013 August 30, we observed bursts of high Doppler shifts suggesting strong supersonic downflows of up to 200 km/s and weaker, slightly slower upflows in the spectral lines Mg II h and k, C II 1336 Å, Si IV 1394 Å, and 1403 Å, that are correlated with brightenings in the slitjaw images (SJIs). The bursty behavior lasts throughout the 2 hr observation, with average burst durations of about 20 s. The locations of these short-lived events appear to be the umbral and penumbral footpoints of EUV loops. Fast apparent downflows are observed along these loops in the SJIs and in AIA, suggesting that the loops are thermally unstable. We interpret the observations as cool material falling from coronal heights, and especially coronal rain produced along the thermally unstable loops, which leads to an increase of intensity at the loop footpoints, probably indicating an increase of density and temperature in the TR. The rain speeds are on the higher end of previously reported speeds for this phenomenon, and possibly higher than the free-fall velocity along the loops. On other observing days, similar bright dots are sometimes aligned into ribbons, resembling small flare ribbons. These observations provide a first insight into small-scale heating events in sunspots in the TR.

A particular problem dealt with here is to calculate the partition function of massless scalar field in Schwarzschild background.

title: The dogma of the Iberian origin of the Bell Beaker: attempting its deconstruction
Creators: name: Jeunesse, Christian
Publisher: name: Journal of Neolithic Archaeology
Year: 2015

description: The hypothesis of an Iberian origin of the Bell Beaker has been advanced from the beginning of the 20th century on. For a time challenged by the assumption of a cradle located rather in the north-western part of continental Europe, it is currently making a comeback and is supported by most specialists of the Bell Beaker phenomenon. An examination of the conditions related to its construction demonstrates that its dominant position owes more to contingent causes such as the charismatic personalities of its creators and their study areas than to an objective analysis of the archaeological record. A small exercise of archaeology-fiction in which we will trace back the history of research based on the assumption of a central-European origin highlights the structural weakness and the dogmatic character of the hypothesis of the Iberian cradle.

description: Land degradation occurs in all kinds of landscapes over the world, but the drivers of land degradation vary from region to region. Identifying these drivers at the appropriate spatial scale is an essential prerequisite for developing and implementing appropriate area-specific policies. In this study, we investigate nine different driving factors in three categories: human disturbance, water condition, and urbanisation. Using partial order theory and the Hasse diagram technique, we analyse the temporal and spatial dynamics of these drivers and identify the major drivers of land degradation at the county level in the Xilingol League, China. Our findings indicate that: (i) in eight out of the region’s 12 counties, human disturbance was the dominant driver responsible for land degradation up to 2000, followed by water conditions, while urbanisation was the dominant driver in only four counties; (ii) the effects resulting from human disturbance and water availability decreased after 2000, while urbanisation became the dominant driver for land degradation in seven counties. The influence of human disturbance in this region has decreased, which suggests that ecological protection policies that were designed to control population and livestock numbers have worked as intended for this region. However, land degradation has continued and new policy measures are required to ease the effect of urbanisation.

description: A systematic investigation of the causes. and effects of the window of a surface barrier detector is described. The effect of the surface treatment is shown to be Significant in deter mining the resulting window thickness; and the influence of the magnitude of the electric field within the depletion region is demonstrated. An explanation for the origin of this effect is proposed, differing from previous models by including all the possible charge collection and loss modes. The predictions of this theory are compared with window thickness measurements, and also with plasma time measurements made independently.

description: For over a century, excavations on Trypillia sites in Ukraine and Moldova, as well as on Cucuteni sites in Romania, have revealed few obvious signs of architectural differentiation among the huge numbers of domestic houses. Now, for the first time, a new generation of geophysical prospection methods used to investigate mega-sites has revealed uncommonly large Trypillia structures which merit the name ‘mega-structures’. The first three such mega-structures were identified in geophysical prospection in 2009 at the mega-site of Nebelivka, Kirovograd Domain, Ukraine. This article provides a preliminary report on the excavation of the largest mega-structure in the summer 2012 season. This building, covering an area of 600m2, must rank as one of the largest structures ever built in prehistoric Europe.

Recent upper Arctic Ocean warming expedited by summertime atmospheric processes

Publisher: name: Zenodo

description: Presented at the GHRSST XXIII international science team meeting, 27 June-1 July 2022, online and in-person (Barcelona). #GHRSST23 Short abstract The observed upper (0–50 m) Arctic Ocean warming since 1979 has been primarily attributed to anthropogenically driven changes in the high latitudes. Here, using both observational and modeling analyses, we demonstrate that a multiyear trend in the summertime large-scale atmospheric circulation, which we ascribe to internal variability, has played an important role in upper ocean warming in summer and fall over the past four decades due to sea ice-albedo effect induced by atmospheric dynamics. Nudging experiments in which the wind fields are constrained toward the observed state support this mechanism and suggest that the internal variability contribution to recent upper Arctic Ocean warming accounts for up to one quarter of warming over the past four decades and up to 60% of warming from 2000 to 2018. This suggests that climate models need to replicate this important internal process in order to realistically simulate Arctic Ocean temperature variability and trends.

description: Plastic-derived pollutants are hazardous and pervasive in the environment, and their detection is a challenge due to observational constraints of various dimensions. Physical, chemical, thermal, and spectroscopic methods are extensively used to identify microplastics in environmental systems, but fundamental challenges exist in the isolation and analysis of nanoplastics from environmental samples. The promising practices are often destructive, rendering the samples inutile for further investigations. In this paper, a technique based on the measurement of the dielectric properties of the samples, carried out using the rectangular cavity perturbation technique at the S?band of microwave frequency of 2–4 GHz is proposed. The ability of this method to identify some of the most abundant types of plastics found in the environment, polypropylene, low-density polyethylene, high-density polyethylene, and cross-linked polyethylene, is demonstrated. Electrical characteristics at microwave fre?quencies such as absorption factor, dielectric constant, and dielectric loss tangent are found useful in the identification of various polymers in the samples. Further, this method can be applied to identify other envi?ronmentally stable performance and engineering polymers, which are not often investigated in the environ?mental matrices for their hazardous effects. This non-destructive measurement method is quick and straightforward and can be further developed to identify a wide range of plastic materials present in various environmental compartments.

Abundance sensitive points of line profiles in the stellar spectra

Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Many abundance studies are based on spectrum synthesis and $χ$-squared differences between the synthesized and an observed spectrum. Much of the spectra so compared depend only weakly on the elemental abundances. Logarithmic plots of line depths rather than relative flux make this more apparent. We present simulations that illustrate a simple method for finding regions of the spectrum most sensitive to abundance, and also some caveats for using such information. As expected, we find that weak features are the most sensitive. Equivalent widths of weak lines are ideal features, because of their sensitivity to abundances, and insensitivity to factors that broaden the line profiles. The wings of strong lines can also be useful, but it is essential that the broadening mechanisms be accurately known. The very weakest features, though sensitive to abundance, should be avoided or used with great caution because of uncertainty of continuum placement as well as numerical uncertainties associated with the subtraction of similar numbers.

A Study Of Epoxide Resin Based Scintillators

Publisher: name: London South Bank University
Year: 1983

description: The object of this study was to examine the feasibility for the production of commercially viable scintillators, and to investigate the mechanism of energy transfer to enable maximum efficiency to be achieved. Various concentrations of the aliphatic amine hardener XD 716 (125) (a polyoxypropyleneamine) were used to cross-link resin MY 790 (adistilled diglycidylether of bisphenol-A resin of equivalent weight 190). Clear, colourless castings were obtained, with the requisite physical properties; shrinkage less than 5%, and the refractive index about 1.46. Of the various primary solutes studied, PPO (2,5-diphenyloxazole) was found to be the most suitable, in terms of light output under Strontium-90 beta-particle irradiation, with high solubility in the epoxide resin. Scintillators containing the secondary solute bis-MSB (1,4-di-(2-methylstyryl)-benzene) gave the highest light output under Strontium-90 beta-particle irradiation, when measured relative to a polyvinyltoluene-based scintillator NE 102A, (136 Excimer fluorescence was observed from epoxide resin scintillators containing PPO at all PPO concentrations employed, and irrespective of amine or naphthalene concentration. This accounts for the concentration quenching observed under beta-particle irradiation. Non-fluorescent exciplex formation between naphthalene and the polyoxypropyleneamine curing agent satisfactorily explains the quenching observed when naphthalene was added to these scintillators. Energy transfer was studied qualitatively by fluorescence decay time measurements using the method of Swank and Buck. 20) It was found that efficient non-radiative energy transfer occurred from the cured epoxide resin to PPO, but that the addition of naphthalene to these systems prevented this type of energy transfer. Energy transfer from the cured epoxide resin to PPO is described satisfactorily by Foérster-type expressions.(77-82) Efficiencies derived from these expressions compare favourably with those obtained -from energy transfer data. R_, the critical transfer distance at which energy transfer and spontaneous deactivation are of equal probability was found to be between 2.5 - 3.5 nm.

description: Dunaliella species are a unique group of microalgae known for their remarkable ability to thrive in extremely saline environments, making them a subject of significant interest in biotechnology. In this study, we evaluate six representatives belonging in five species of Dunaliella, isolated from Greek solar saltworks (D. asymmetrica TAU-MAC 0620, D. viridis TAU-MAC 0920, D. granulata TAU-MAC 1120, D. minutissima TAU-MAC 1220, D. granulata TAU-MAC 1420 and D. polymorpha TAU-MAC 1520) for their growth performance and their capacity to accumulate carotenoids in response to various growth parameters. We employed an L9 Taguchi fractional experimental design to assess the impact of illumination, salinity, and nitrogen supply, each tested at three different levels. Analysis of variance revealed that the growth performance of all Dunaliella strains was primarily dictated by the applied level of light intensity, while for some strains the salinity and nitrogen supply also contribute as a significant co-factor for their growth. Overall, and despite some strain specific behaviors in response to the different levels of the applied factors, Dunalliella TAU-MAC strains seem to follow a closely similar pattern for their growth. Thus, they maximize their growth performance under the influence of the moderate level of illumination (100 μmol m-2 s-2), the moderate or even the high level of salinity (60 or 120 g NaCl L-1, respectively) , and the low level of nitrogen availability (0.2 g KNO3 L-1). Our results showed that all the examined strains were non-carotenogenic. Among the studied Dunaliella strains, D. granulata TAU-MAC 1420 showed an elevated carotenoids accumulation capacity especially under the influence of the moderate level of light intensity and the high level of salinity, achieving almost 10 mg of carotenoids production L-1, while the highest carotenoid concentration for the other Dunaliella strains was significantly lower, typically below 5 mg L-1. Through this research, we anticipate uncovering critical insights into the growth behavior and carotenoid accumulation patterns of several lesser-studied Dunaliella species.

description: Analysis of emission lines in gaseous nebulae yields direct measures of physical conditions and chemical abundances and is the cornerstone of nebular astrophysics. Although the physical problem is conceptually simple, its practical complexity can be overwhelming since the amount of data to be analyzed steadily increases; furthermore, results depend crucially on the input atomic data, whose determination also improves each year. To address these challenges we created PyNeb, an innovative code for analyzing emission lines. PyNeb computes physical conditions and ionic and elemental abundances, and produces both theoretical and observational diagnostic plots. It is designed to be portable, modular, and largely customizable in aspects such as the atomic data used, the format of the observational data to be analyzed, and the graphical output. It gives full access to the intermediate quantities of the calculation, making it possible to write scripts tailored to the specific type of analysis one wants to carry out. In the case of collisionally excited lines, PyNeb works by solving the equilibrium equations for an n-level atom; in the case of recombination lines, it works by interpolation in emissivity tables. The code offers a choice of extinction laws and ionization correction factors, which can be complemented by user-provided recipes. It is entirely written in the python programming language and uses standard python libraries. It is fully vectorized, making it apt for analyzing huge amounts of data. The code is stable and has been benchmarked against IRAF/NEBULAR. It is public, fully documented, and has already been satisfactorily used in a number of published papers.

description: The interaction effect of haemoglobin genotypes (HbAA, HbAB) and residual feed intake (RFI) classes (RFILL, RFIMM, RFIHH) on feed efficiency, haematological and serum parameters in on-farm West African Dwarf (WAD) does was studied for pre-selection of breeding animals. Ninety-six does were fed for 112 days. Feed intake was measured daily, body weight and other variables were measured at 28-day intervals. Dry matter intake (DMI); average daily gain (ADG) and feed conversion efficiency (FCE) were computed while body condition score (BCS) was estimated using the five-point scale for goats. Blood samples were collected after 112 days via jugular vein puncture and analyzed for insulin-like growth factor (IGF-I), insulin, leptin, urea and complete cell counts. Phenotypic RFI was calculated for each animal as the residual from a multiple regression model of DMI on ADG and mid-test metabolic bodyweight (BW0.75). The WAD does with heterozygous HbAB genotype had higher serum insulin and IGF-1 concentrations than the homozygous HbAA genotype (P < 0.019). Does within the low RFI (RFILL) class recorded higher IGF-1 (P < 0.050 ), PCV (P < 0.002 ) and Hb concentration (P < 0.038) than does within the medium (RFIMM) and high (RFIHH) classes. The interaction of Hb genotype and RFI revealed significant differences (P < 0.050) on FCE, IGF-1 and monocytes values among does. The result of Hb genotype x RFI class interaction on RFI was not significant (P = 0.077), although values increased numerically in ascending order to rank does into pre-selection classes. WAD does of HbAA and HbAB genotypes with negative-RFI values (-0.004, -0.005) were deemed most efficient nutritionally and could be selected as parents.

This mechanism is in sharp contrast with that from the primordial curvature (scalar) perturbations, in which the temperature anisotropies mainly decay by Silk damping effects. We estimate the size of the $μ$ distortion from the new mechanism, which can be used to constrain the amplitude of primordial gravitational waves on smaller scales independently from the CMB anisotropies, giving more wide-range constraint on their spectral index by combining the amplitude from the CMB anisotropies.

description: Familial dysautonomia (FD) is a sensory and autonomic neuropathy caused by mutations in elongator complex protein 1 (ELP1). FD patients have small trigeminal nerves and impaired facial pain and temperature perception. These signals are relayed by nociceptive neurons in the trigeminal ganglion, a structure that is composed of both neural crest- and placode-derived cells. Mice lacking Elp1 in neural crest derivatives (‘Elp1 CKO’) are born with small trigeminal ganglia, suggesting Elp1 is important for trigeminal ganglion development, yet the function of Elp1 in this context is unknown. We demonstrate that Elp1, expressed in both neural crest- and placode-derived neurons, is not required for initial trigeminal ganglion formation. However, Elp1 CKO trigeminal neurons exhibit abnormal axon outgrowth and deficient target innervation. Developing nociceptors expressing the receptor TrkA undergo early apoptosis in Elp1 CKO, while TrkB- and TrkC-expressing neurons are spared, indicating Elp1 supports the target innervation and survival of trigeminal nociceptors. Furthermore, we demonstrate that specific TrkA deficits in the Elp1 CKO trigeminal ganglion reflect the neural crest lineage of most TrkA neurons versus the placodal lineage of most TrkB and TrkC neurons. Altogether, these findings explain defects in cranial gangliogenesis that may lead to loss of facial pain and temperature sensation in FD.

description: Recently, it has been shown that the momentum distribution of a metallic state of fermionic atoms in a lattice Fermi-Bose mixture exhibits coherent oscillations after a global quench that suppresses tunneling. The oscillation period is determined by the Fermi-Bose interaction strength. Here we show that similar dynamics occurs in the fermionic Hubbard model when we quench a noninteracting metallic state by introducing a Hubbard interaction and suppressing tunneling. The period is determined primarily by the interaction strength. Conversely, we show that one can accurately determine the Hubbard interaction strength from the oscillation period, taking into account corrections from any small residual tunneling present in the final Hamiltonian. Such residual tunneling shortens the period and damps the oscillations, the latter being visible in the Fermi-Bose experiment.

Deep-learning models for Single Image Super Resolution: applications to Mediterranean Sea SST products and SST gradients within the Copernicus Marine Service

description: Presented at the GHRSST XXIII international science team meeting, 27 June-1 July 2022, online and in-person (Barcelona). #GHRSST23 Short abstract  In the framework of the Copernicus Marine Service, the Italian National Research Council (CNR) – Institute of Marine Sciences (ISMAR) is responsible for producing and distributing operational near-real-time (NRT) Sea Surface Temperature (SST) products over the Mediterranean and Black Seas. The CNR-ISMAR SST processing chain, which includes several modules, from data extraction and preliminary quality control to cloudy pixel removal and satellite images merging, provides daily (night-time) merged multi-sensor (L3S) and optimally interpolated (L4) foundation SST fields at high (HR) and ultra-high (UHR) spatial resolution (i.e., over 1/16° and 1/100° regular latitude-longitude grids, respectively). However, the effective resolution of UHR L4 products strictly depends on the availability of high-resolution cloud-free measurements. The Optimal Interpolation algorithm makes use of HR L4 data remapped onto a 1/100° regular grid as first-guess (which means UHR SST features are already filtered out) and it is not able to reconstruct small scale features unless valid L3 observations are present within a short temporal window. For this reason, CNR is presently working to improve the MED NRT SST products’ effective resolution and SST gradients’ accuracy through the development of deep learning models. In particular, the application of Convolutional Neural Networks (CNN) in the process of reconstructing high-resolution images from low-resolution ones, the so-called single image Super Resolution (SR) technique, has demonstrated an impressive potential. Here we present preliminary results on the achievements and the limitations in applying this specific class of artificial intelligence techniques to improve the effective resolution (and SST gradients) of our MED-NRT-L4-UHR product.

Exploring MSSM for Charge and Color Breaking and Other Constraints in the Context of Higgs@125 GeV

description: Exploring MSSM parameter space after the discovery of Higgs Boson with mass 125 GeV naturally demands large top-squark mixing or large trilinear coupling parameter $A_t$ in particular, so as to avoid excessively heavy squark, specially for the universal models like CMSSM. We study stability of electroweak symmetry breaking vacua in possible presence of deeper charge-color symmetry breaking minima within MSSM. Besides stable vacua, we consider scenarios characterized by the presence of global CCB minima, with SM like charge and color conserving vacuum, having stability over cosmologically large lifetime {(\it long-lived states)}. We allow vacuum expectation values for both stop as well as sbottom fields, since these belong to the third generation of sfermions with larger Yukawa couplings that have immediate effect on the tunneling time. Moreover, for large $μ$ regions, radiative corrections to Higgs boson mass from bottom-squark loop is quite significant. Regions of MSSM parameters space become viable for large $A_t$ and large $μ$ zones which are generically excluded via the traditional analytical CCB constraints. For a large value of $\tanβ$, safe vacua associated with large values of $|μ|$ and $|A_t|$ are predominantly long-lived and may be associated with relatively light stop masses. We also identify low $μ$ regions associated with long-lived states. Both the above zones can be friendly to muon $g-2$ constraint. We also impose constraints from ${\rm Br}(B \rightarrow X_s γ)$ and ${\rm Br}(B_s \rightarrow μ^+ μ^-)$. We do the analysis for a moderate and a large $\tanβ$. Results are compatible with dark matter related constraints, as expected.

description: We constrain the neutrino mass in $f(R)$ gravity using the latest observations from the Planck, BAO and BICEP2 data. We find that the measurement on the B-modes can break the degeneracy between the massive neutrinos and the $f(R)$ gravity. We find a non-zero value of the Compton wavelengths $B_{0}$ at a $68\%$ confidence level for the $f(R)$ model in the presence of massive neutrinos when the BICEP2 data is used. Furthermore, the tension on the tensor-to-scalar ratios between the measured values from Plank and BICEP2 is significantly reconciled in our model.

description: Three-dimensional (3D) printing, also known as additive manufacturing (AM), is a modern technique/technology, which makes it possible to construct 3D objects from computer-aided design (CAD) digital models. This technology can be used in the progress of drug delivery systems, where porosity has played important role in attaining an acceptable level of biocompatibility and biodegradability with improved therapeutic effects. 3D printing may also provide the user possibility to control the dosage of each ingredient in order to a specific purpose, and makes it probable to improve the formulation of drug delivery systems. This article covers the 3D printing technologies, bioactive materials including natural and synthetic polymers as well as some ceramics and minerals and their roles in drug delivery systems. This technology is feasible to fabricate drug products by incorporating multiple drugs in different parts in such a mode that these drugs can release from the section at a predetermined rate. Furthermore, this 3D printing technology has the potential to transform personalized therapy to various age-groups by design flexibility and precise dosing. In recent years, the potential use of this technology can be realized in a clinical situation where patients will acquire individualized medicine as per their requirement.
