Published: August 2019

AbstractIn recent years, the reconstruction of individual life history by the multi-isotope analysis of different skeletal elements has become an active topic in bioarchaeological field. However, most studies focus on the persons with high social status and none cares for craftsmen with low social status. In this study, we undertook a comprehensive analysis on a human skeleton buried in the Oupan kiln, Anhui, China to recover his osteobiography. The archaeological context and dating result (534–644 cal. AD) indicate that he might be a potter at the kiln during the Sui and early Tang Dynasty, characteristic of low social hierarchy. The osteological investigation suggests that he had abnormal vertebrae related to long-term physical labor. In general, the isotopic data demonstrate that he mainly consumed C3(wheat, beans)/C4(millets)-based terrestrial foods. The isotopic (C, N) profiles of dentin sections and isotopic data (C, O) of bone apatite and teeth enamel indicate that he had experienced dramatic dietary changes and/or several migrations throughout the childhood and adulthood. His turbulent life trajectory was highly relevant to his identity and low social status. Our study provides a pilot insight into the life history of craftsmen who was generally overlooked in archaeological, historic and anthropological research.

AbstractConcrete cracks must be repaired promptly in order to prevent structural damage and to prolong the structural life of the building (or other such construction). Biological self-healing concrete is a recent alternative technology involving the biochemical reaction of microbial induced calcium carbonate precipitation (MICP). This study determined the most appropriate technique to encapsulate spores of Bacillus sphaericus LMG 22257 with sodium alginate so as to protect the bacterial spores during the concrete mixing and hardening period. Three techniques (extrusion, spray drying and freeze drying) to encapsulate the bacterial spores with sodium alginate were evaluated. The freeze-drying process provided the highest bacterial spore survival rate (100%), while the extruded and spray-dried processes had a lower spore survival rate of 93.8% and 79.9%, respectively. To investigate the viability of microencapsulated spores after being mixed with mortar, the decomposed urea analysis was conducted. The results revealed that the freeze-dried spores also showed the highest level of urea decomposition (metabolic activity assay used as a surrogate marker of spore germination and vegetative cell viability). Thus, the self-healing performance of concrete mixed with freeze-dried spores was evaluated. The results showed that the crack healing ratio observed from the mortar specimens with freeze-dried microencapsulated spores were significantly higher than those without bacteria. This study revealed that freeze drying has a high potential as a microencapsulation technique for application to self-healing concrete technology.

AbstractThe complex interactions between orbital angular momentum (OAM) of light and atoms are particularly intriguing in the areas of quantum optics and quantum information. Building a versatile high-dimensional quantum network needs broad spiral-bandwidth for preparing higher-quanta OAM mode and resolving the bandwidth mismatch in spatial space. Here, we demonstrate a broad spiral-bandwidth quantum-interface between photon and memory. Through twisted fields of the writing and reading, the correlated OAM distribution between photon and memory is significantly broadened. This broad spiral-bandwidth quantum-interface could be spanned in multiplexing regime and could work in high-quanta scenario with capability of $$\vert l\vert =$$

l

. Such state-of-the-art technology to freely control the spatial distribution of OAM memory is very helpful to construct high-dimensional quantum networks and provides a benchmark in the field of actively developing methods to engineer OAM single photon from matters.

Published: August 2019

Abstract
The coordination of Cu(ii) ions by the Ac-KGHGNGEEGTPTVHNE-NH2 (1L) peptide – a FomA protein fragment of Fusobacterium nucleatum – and its cyclic analogue: cyclo(KGHGNGEEGTPTVHNE) (2L) was studied by potentiometric titration, spectroscopic methods (UV-Vis, CD, EPR) and mass spectrometry (MS). Both the ligands contain two histydyl residues located in the third and fourteenth position of the peptide chain. For the 1L and 2L ligands mono- and dinuclear complexes were identified and studied in an aqueous solution. At the pH range characteristic of the intestinal environment (5.5–7.5), copper(ii) complexes were identified and their formation constants were determined. The same forms of the complexes with respectively the linear peptide and the cyclic peptide show similar stability, but greater than that reported in the literature for complexes with the same coordination mode. Moreover, the 1L peptide and its complex exhibit an α-helix structure, whereas the 2L peptide adopts this secondary structure only after coordination with the metal ion.
The Great Escape: how phosphatidylinositol 4-kinases and PI4P promote vesicle exit from the Golgi (and drive cancer)
Authors: Waugh Mark G. 
Published: August 2019

Abstract
Phosphatidylinositol 4-phosphate (PI4P) is a membrane glycerophospholipid and a major regulator of the characteristic appearance of the Golgi complex as well as its vesicular trafficking, signalling and metabolic functions. Phosphatidylinositol 4-kinases, and in particular the PI4KIIIβ isoform, act in concert with PI4P to recruit macromolecular complexes to initiate the biogenesis of trafficking vesicles for several Golgi exit routes. Dysregulation of Golgi PI4P metabolism and the PI4P protein interactome features in many cancers and is often associated with tumour progression and a poor prognosis. Increased expression of PI4P-binding proteins, such as GOLPH3 or PITPNC1, induces a malignant secretory phenotype and the release of proteins that can remodel the extracellular matrix, promote angiogenesis and enhance cell motility. Aberrant Golgi PI4P metabolism can also result in the impaired post-translational modification of proteins required for focal adhesion formation and cell–matrix interactions, thereby potentiating the development of aggressive metastatic and invasive tumours. Altered expression of the Golgi-targeted PI 4-kinases, PI4KIIIβ, PI4KIIα and PI4KIIβ, or the PI4P phosphate Sac1, can also modulate oncogenic signalling through effects on TGN-endosomal trafficking. A Golgi trafficking role for a PIP 5-kinase has been recently described, which indicates that PI4P is not the only functionally important phosphoinositide at this subcellular location. This review charts new developments in our understanding of phosphatidylinositol 4-kinase function at the Golgi and how PI4P-dependent trafficking can be deregulated in malignant disease.
Pre-Attentive Neural Signatures of Auditory Spatial Processing in Listeners With Normal Hearing and Sensorineural Hearing Impairment: A Comparative Study
Authors: Nisha K. V. , Kumar U. Ajith 
Published: August 2019

Purpose
This study was carried out to understand the neural intricacies of auditory spatial processing in listeners with sensorineural hearing impairment (SNHI) and compare it with normal hearing (NH) listeners using both local and global measures of waveform analyses.

Method
A standard group comparison research design was adopted in this study. Participants were assigned to 2 groups. Group I consisted of 13 participants with mild–moderate flat or sloping SNHI, while Group II consisted of 13 participants with NH sensitivity. Electroencephalographic data using virtual acoustic stimuli (spatially loaded stimuli played in center, right, and left hemifields) were recorded from 64 electrode sites in passive oddball paradigm. Both local (electrode-wise waveform analysis) and global (dissimilarity index, electric field strength, and topographic pattern analyses) measures were performed on the electroencephalographic data.

Results
Results of local waveform analyses marked the appearance of mismatch negativity in an earlier time window, relative to those reported conventionally in both the groups. The global measures of electric field strength and topographic modulations (dissimilarity index) revealed differences between the 2 groups in different time periods, indicating multiphases (integration and consolidation) of spatial processing. Further, the topographic pattern analysis showed the emergence of different scalp maps for SNHI and NH in the time window corresponding to mismatch negativity (78–150 ms), suggestive of differential spatial processing between the groups at the cortical level.

Conclusions
The findings of this study highlights the differential allotment of neural generators, denoting variations in spatial processing between SNHI and NH individuals.
Test–Retest Reliability of Multicomponent Tympanometry at 226-, 678-, and 1000-Hz Probe Tones Over 10 Sessions
Authors: Singh Niraj Kumar , Baral Trupti Lata 
Published: August 2019

Purpose
Numerous studies are testimony to the pivotal role of multicomponent tympanometry in diagnosis and differential diagnosis of auditory pathologies, not only of the middle ear but also the inner ear. Repeated measurements using multicomponent tympanometry have been used as a measure for stapedial tendon preservation during middle ear surgeries. However, such applications would produce reliable results only when multicomponent tympanometry produces replicable results across sessions. Nonetheless, there is dearth of studies exploring the test–retest repeatability of multicomponent tympanometry across multiple sessions using various probe tones. Therefore, this study aimed at examining the test–retest reliability of multicomponent tympanometry across 10 different sessions for 226-, 678-, and 1000-Hz probe-tone frequencies.

Method
The study included 28 healthy adults in the age range of 18 to 25 years. All participants underwent multicomponent (susceptance and conductance) tympanometry using 226-, 678-, and 1000-Hz probe tones.

Results
Multicomponent tympanometry showed excellent test–retest reliability for all parameters of 226- and 678-Hz probe tones. The probe tone of 1000 Hz produced excellent test–retest reliability for most of the parameters.

Conclusions
The clinical recording of multicomponent tympanometry over multiple sessions is more reliable when using 226- and 678-Hz probe tones. Hence, these probe tones lend themselves to possible applications requiring multiple recordings, such as evaluation of treatment outcomes or preservation of middle ear structures during surgery.
Intersession Variations in Frequency Tuning of Ocular Vestibular Evoked Myogenic Potentials in Healthy Individuals

Published: August 2019

ObjectiveFrequency tuning of ocular vestibular evoked myogenic potential (oVEMP), which is the stimulus frequency corresponding to the largest oVEMP amplitude, has been used to diagnose cases with Ménière's disease and differentiate them from cases with benign paroxysmal positional vertigo with a high degree of sensitivity and specificity. However, this measure of oVEMP is carved out of the peak-to-peak amplitude of oVEMP, and studies on test–retest reliability of amplitude of oVEMP have shown moderate-to-excellent reliability of amplitude. This would theoretically render the frequency tuning of oVEMP susceptible to variations across multiple recordings. This being the case, erroneous conclusions regarding the presence of Ménière's disease could be made if the frequency tuning varies between recordings. However, there is no published report regarding the test–retest reliability of frequency tuning measure of oVEMP even in healthy individuals, to the best of our knowledge. Therefore, this study aimed to study the test–retest reliability of frequency tuning of oVEMP in healthy individuals.MethodThe study included 20 healthy adults in the age range of 18–25 years. All participants underwent oVEMP recording in 4 different sessions, with each session consisting of oVEMP recording for octave and midoctave tone-burst frequencies from 250 to 2000 Hz.ResultsThe results revealed no significant difference in frequency tuning of oVEMP among the sessions (p> .05). The intraclass correlation coefficient for frequency tuning data was found to be .857.ConclusionThe frequency tuning of oVEMP has excellent test–retest reliability and therefore lends itself to applications requiring multiple sessions of recording.
Magnetic field vector ambiguity resolution in a quiescent prominence observed on two consecutive days
Authors: Kalewicz T. , Bommier V. 
Published: August 2019

Context. Magnetic field vector measurements are always ambiguous, that is, two or more field vectors are solutions of the observed polarisation.
Aims. The aim of the present paper is to solve the ambiguity by comparing the ambiguous field vectors obtained in the same prominence observed on two consecutive days. The effect of the solar rotation is to modify the scattering angle of the prominence radiation, which modifies the symmetry of the ambiguous solutions. This method, which is a kind of tomography, was successfully applied in the past to the average magnetic field vector of 20 prominences observed at the Pic du Midi. The aim of the present paper is to apply this method to a prominence observed with spatial resolution at the THÉMIS telescope (European site at Izaña, Tenerife Island).
Methods. The magnetic field vector is measured by interpretation of the Hanle effect observed in the He I D3 5875.6 Å line, within the horizontal field vector hypothesis for simplicity. The ambiguity is first solved by comparing the two pairs of solutions obtained for a “big pixel” determined by averaging the observed Stokes parameters in a large region at the prominence centre. Each pixel is then disambiguated by selecting the closest solution in a propagation from the prominence centre to the prominence boundary.
Results. The results previously obtained on averaged prominences are all recovered. The polarity is found to be inverse with a small angle of about −21° between the magnetic field vector and the long axis of the filament. The magnetic field strength of about 6 G is found to slightly increase with height, as previously observed. The new result is the observed decrease with height, of the absolute value of the angle between the magnetic field vector and the long axis of the filament.
Conclusions. This result is in excellent agreement with prominence magnetohydrodynamical models.

Aims. We aim at detecting water vapor in the atmosphere of the hot Jupiter HD 209458 b and perform a multi-band study in the near infrared with CARMENES.
Methods. The water vapor absorption lines from the atmosphere of the planet are Doppler-shifted due to the large change in its radial velocity during transit. This shift is of the order of tens of km s−1, whilst the Earth’s telluric and the stellar lines can be considered quasi-static. We took advantage of this shift to remove the telluric and stellar lines using SYSREM, which performs a principal component analysis including proper error propagation. The residual spectra contain the signal from thousands of planetary molecular lines well below the noise level. We retrieve the information from those lines by cross-correlating the residual spectra with models of the atmospheric absorption of the planet.
Results. We find a cross-correlation signal with a signal-to-noise ratio (S/N) of 6.4, revealing H2O in HD 209458 b. We obtain a net blueshift of the signal of –5.2 −1.3+2.6 km s−1 that, despite the large error bars, is a firm indication of day- to night-side winds at the terminator of this hot Jupiter. Additionally, we performed a multi-band study for the detection of H2O individually from the three near infrared bands covered by CARMENES. We detect H2O from its 0.96–1.06 μm band with a S/N of 5.8, and also find hints of a detection from the 1.06–1.26 μm band, with a low S/N of 2.8. No clear planetary signal is found from the 1.26–1.62 μm band.
Conclusions. Our significant H2O signal at 0.96–1.06 μm in HD 209458 b represents the first detection of H2O from this band individually, the bluest one to date. The unfavorable observational conditions might be the reason for the inconclusive detection from the stronger 1.15 and 1.4 μm bands. H2O is detected from the 0.96–1.06 μm band in HD 209458 b, but hardly in HD 189733 b, which supports a stronger aerosol extinction in the latter, in line with previous studies. Future data gathered at more stable conditions and with larger S/N at both optical and near-infrared wavelengths could help to characterize the presence of aerosols in HD 209458 b and other planets.
Influence of carbonation on the resistance of concrete structures to chloride penetration and corrosion

Published: August 2019

Chloride-induced corrosion of steel rebar embedded in concrete is one of the major concerns influencing the durability of reinforced concrete structures. It is widely recognized that the carbonation in concrete affects the chloride diffusivity and accelerates the chloride-induced reinforcement corrosion. However, only very limited studies have dealt with this issue in the literature. The presence of service load related cracks also affects the reinforcement corrosion. This study aims to investigate the potential impact of concrete carbonation on the chloride penetration resistance, and degree of corrosion, in RC structures subjected to service related microcracks.The experimental programme involves casting of concrete prisms (100 x 100 x 500 mm) with different water-cement ratios (w/c) of 0.4, 0.5 and 0.6 and with four different crack widths (0, 0.05-0.15 mm, 0.15-0.25 mm and 0.25-0.35 mm). These samples were exposed initially to accelerated carbon dioxide (CO2) environment and then exposed to the accelerated chloride environment. Carbonation depth, chloride penetration, and the degree of corrosion (using half-cell) were experimentally measured. The results indicated that (i): The depth of carbonation increases with the increase in crack width and w/c ratio, (ii) chloride penetration depth in concrete structures increases significantly due to the influence of carbonation and (iii) half-cell corrosion potential increases significantly when carbonated concrete samples are exposed to the chloride environment relative to the uncarbonated concrete samples.

Published: August 2019

Purpose To observe the technical and clinical outcome as well as safety of CT fluoroscopy-guided drain placement in the multimodal clinical complication management of superinfected gastric leakage after sleeve gastrectomy.
Materials and Methods All consecutive patients who underwent CT fluoroscopy-guided drain placement to treat superinfected postoperative leakage after sleeve gastrectomy in our department between 2007 and 2014 were included in this retrospective study. All interventions were performed on a 16- or 128-row CT scanner under intermittent CT fluoroscopy guidance (15–25 mAs, 120 kV). The technical and clinical success rates as well as complications, additional therapies and patient radiation dose were analyzed.
Results 14 patients (mean age: 43.8 ± 11.3 years, mean BMI: 52.9 ± 13.5, 7 women) who underwent a total of 31 CT fluoroscopy-guided drain placement procedures were included. 30 of 31 interventions (96.8 %) were technically successful. 7 patients underwent more than one intervention due to drain obstruction or secondary dislocation or as further treatment. During and after the intervention no procedure-associated complications occurred. In all patients, inflammation parameters decreased within days after the CT-guided intervention. The total interventional dose length product (DLP) was 1561 ± 1035 mGy*cm.
Conclusion CT fluoroscopy-guided drain placement has been shown to be a safe minimally invasive procedure that rarely leads to complications for treating superinfected gastric leakage occurring after sleeve gastrectomy. We assume that operative revisions in a high-risk patient group can be avoided using this procedure.
