Submarine volcanic activity and giant amygdale formation along the Panama island arc as a precursor to 6000-year-old agate exploitation on Pedro González Island

Abstract An extensive deposit of agate occurs in Pedro González Island in the Gulf of Panama. Previous archaeological research showed that the agate was exploited between 6200 and 5600 cal BP to make stone tools found at the oldest known Preceramic human settlement in the Pearl Island archipelago. We constrain here the origin and geological context of the agate through a geological and geochemical study of the island. We show that it includes primary volcanic breccias, lavas, and tuffaceous marine deposits with sedimentary conglomerates and debris flow deposits, which we define as the Pedro González Formation. This formation records submarine to subaerial volcanic activity along an island arc during the Oligo-Miocene, confirming previous regional models that favour progressive emergence of the isthmus in the early Miocene. The igneous rocks have an extreme tholeiitic character that is interpreted to reflect magmatic cessation in eastern Panama during the early Miocene. The agate is hosted in andesitic lavas in unusually large amygdales up to 20–40 cm in diameter, as well as small amygdales (0.1–1.0 cm) in a bimodal distribution, and in veins. The large size of the agates made them suitable for tool manufacture. Field evidence suggests that the formation of large amygdales resulted from subaqueous lava–sediment interaction, in which water released from unconsolidated tuffaceous deposits at the base of lava flows rose through the lavas, coalesced, and accumulated below the chilled lava top, with subsequent hydrothermal mineralization. These amygdales could therefore be regarded as an unusual result of combined peperitic and hydrothermal processes.
Genotypic variability of grain phytic acid, mineral bioavailability, and their relation to foliar Zn application

ABSTRACT Phytic acid (PA) is the most prevalent storage form of grain phosphorus (P) and acts as an anti-nutrient by lowering mineral bioavailability. Genotypic variation of grain PA and its relation to mineral bioavailability, and their nutritional fortification potential with zinc (Zn) supply has not been fully investigated in pigmented rice. Here, we compared the differences in grain PA concentration and mineral bioavailability among 13 pigmented rice (red, yellow, and green rice) and six non-pigmented rice cultivars (three common white rice and their corresponding low-PA (lpa) mutant). Pigmented rice was enriched with micronutrients, especially Zn and Fe, on an average of 39.1 and 44.8 mg kg-1 as compared with 31.9 and 33.1 mg kg-1 in non-pigmented rice respectively. The lpa cultivars showed the highest bioavailability for most of the minerals. However, no significant difference was observed for mineral bioavailability between pigmented and common white rice, owing to higher anti-nutritional PA in pigmented rice (9.25 g kg-1) than in common white rice (8.29 g kg-1). However, a large difference in grain PA was found among green rice (11.19 g kg-1), yellow rice (9.82 g kg-1) and red rice (8.56 g kg-1) cultivars. Therefore, foliar Zn was used to investigate PA concentration and Zn bioavailability. Foliar Zn application increased grain Zn but decreased grain PA concentration, which ultimately increased grain Zn bioavailability. Zn application had a remarkable effect on Zn bioavailability for red rice (an average of 82%) as compared with common white rice (48%). These findings could provide helpful knowledge for pigmented rice fortification.
QUANTIFYING AND MANAGING THE INFLUENCE OF MAINTENANCE ACTIONS ON THE SURVIVABILITY OF MESH- RESTORABLE NETWORKS

Summary – In an extensive quickly growing DWDM transport network the frequency of in-service upgrades or other required maintenance activity may be high. We are therefore interested in defining, quantifying and managing the theoretical risk that a “maintenance outage” may have for the rest of a meshrestorable network. The point of view is of putting one span in maintenance and then asking, if a failure occurs to another span while in the maintenance state, what is the risk of incomplete restoration? In ring networks, the corresponding exposure to failure is contained within the specific ring involved. But the price for this containment is the 100% redundancy of rings and that the risk is of 100% restorability loss on other spans when in a maintenance state. We find that mesh networks exhibit a more distributed risk field, but much lower risk magnitudes. In over 2500 trials with a mesh equivalent of roll-to-prote ction as the maintenance model no other span sustained over 70% theoretical loss of restorability and 99.6% of the time the theoretical risk to restorability was < 50%. This gives an important operational advantage in support of priority service paths. We give a procedure for calculating the ‘theoretical risk field’ of a given maintenance action in a mesh-restorable network. We then study the effects of various mesh-network design differences on the extent and magnitude of the theoretical risk field. We produce results for a worst-case (“equivalent to failure”) model for maintenance and the mesh equivalent of “roll to protection” in rings. The basic methods can be adapted for other maintenance models or models of the restoration process or adapted to handle multiple maintenance scenarios. The work is aimed at understanding and managing the effects of maintenance in a mesh-restorable network and ultimately providing new operational and design capabilities for future mesh-based network planning and operations systems.
Application of ultrasound markers measured at different time points of COH cycle in the prediction of ovarian response for individualised ovulation induction

Abstract The purpose of this study was to evaluate the predictive value of ultrasound markers measured at different time points of the controlled ovarian hyperstimulation (COH) cycle on ovarian response and outcome indicators in the IVF-ET cycle. According to the oestrogen level and the number of retrieved oocytes, patients who planned for COH treatment were separated into low-response group, normal and high-response group. The ovarian stromal artery flow parameters on the day of pituitary down-regulation, day 1, day 7, day 10, and the day of hCG injection were collected prospectively. We also have collected the data of cumulus oophorus count on the day of hCG injection by transvaginal sonography. Compared with the low-response group, on the first day of the COH cycle PI, RI, and S/D were lower in the high-response group than they were in the low-response group (p < .05). PSV and EDV were significantly higher in the high-response group than they were in the low-response group (p < .01), and the PSV on the first day of the COH cycle have statistical significance in predicting the number of high-quality embryos. The number of cumulus oophorus on the day of hCG injection has statistical significance in predicting the number of oocytes retrieved and fertilised oocytes. We conclude that the ovarian stromal artery flow parameters on the first day of the COH cycle and cumulus oophorus count on hCG injection day can serve as efficient indicators for an early assessment of ovarian response and individualised ovulation induction. IMPACT STATEMENT What is already known on this subject? AMH, AFC, and the age of the patient are well-known effective parameters for the evaluation of ovarian response, but these are insufficient and full of individual differences. Some researchers have investigated the value of colour Doppler ultrasound and cumulus oophorus in assessing ovarian response, but no definitive conclusion has been reached. What do the results of this study add? The hemodynamic parameters of ovarian stromal artery on the first day of the COH cycle and the number of cumulus oophorus on the day of hCG injection detected by Transvaginal Colour Doppler Sonography (TV-CDS) could be used to predict the ovarian response. What are the implications of these findings for clinical practice and/or further research? Ovarian stromal artery flow parameters and cumulus oophorus detected by TV-CDS can potentially be offered as a complementary parameter for ovarian reserve.
Three Dimensional Movements Of The Upper Cervical Spine

Ten fresh cadaveric whole cervical spine specimens (occiput to C7) were studied using well established techniques to document the movements in flexion, extension, left and right lateral bending and left and right axial rotation. Pure moments of maximum 1.5 newton meters were applied incrementally and three dimensional movements of the bones were recorded using stereophotogrammetry. Each moment was applied individually and in a three load/unload cycles. The motion measurements were made on the third load cycle. Parameters of neutral zone, elastic zone and range of motion were computed. Neutral zones for flexion/extension, right/left lateral bending and right/left axial rotation were respectively: 1.1, 1.5 and 1.6 (occiput-C1); and 3.2, 1.2 and 29.6 degrees (C1-C2). Ranges of motion for flexion, extension, lateral bending (one side) and axial rotation (one side) were respectively: 3.5, 21.0, 5.5 and 7.2 degrees (occiput-Cl joint) and 11.5, 10.9, 6.7 and 38.9 degrees (CI-CZ joint). The highest intervertebral motion in the spine was the axial rotation at the Cl-C2 joint, neutral zone constituting 75% of this motion.
Essential Oils from Zingiber striolatum Diels Attenuate Inflammatory Response and Oxidative Stress through Regulation of MAPK and NF-κB Signaling Pathways

Zingiber striolatum Diels (Z. striolatum), a widely popular vegetable in China, is famous for its medicinal and nutritional values. However, the anti-inflammatory effects of essential oil from Z. striolatum (EOZS) remain unclear. In this study, EOZS from seven regions in China were extracted and analyzed by GC–MS. LPS-induced RAW264.7 cells and 12-O-Tetradecanoylphorbol 13-acetate (TPA)-stimulated mice were used to evaluate the anti-inflammatory effects of EOZS. Results show that 116 compounds were identified in EOZS from seven locations. Samples 2, 4 and 5 showed the best capability on DPPH radical scavenging and NO inhibition. They also significantly reduced the production of ROS, pro-inflammatory cytokines, macrophage morphological changes, migration and phagocytic capability. Transcriptomics revealed MAPK and NF-κB signaling pathways may be involved in the anti-inflammatory mechanism, and the predictions were proven by Western blotting. In TPA-induced mice, EOZS reduced the degree of ear swelling and local immune cell infiltration by blocking the activation of MAPK and NF-κB signaling pathways, which was consistent with the in vitro experimental results. Our research unveils the antioxidant capability and potential molecular mechanism of EOZS in regulating inflammatory response, and suggests the application of EOZS as a natural antioxidant and anti-inflammatory agent in the pharmaceutical and functional food industries.
Modeling the Cyclic Flexural and Shear Response of the R. C. Hollow Box Columns of an Existing Viaduct

The cyclic response of R.C. hollow box columns, constructed as part of a typical single-column bent viaduct, built in the 1970’s in Central Europe, was studied both experimentally and analytically. Moderate displacement ductility capacity (between 3 and 4) was observed regardless of the column construction details, which are nowadays considered inappropriate for seismic regions. Standard analytical flexural models correlated with the experimental results quite well. Shear strength was estimated using the two methods included in the EC8 standards, as well as the method developed at the University of California, San Diego. Quite different results were obtained. The most accurate was the third method.
Difference in Housing Finance Usage and Its Impact on Housing Wealth Inequality in Urban China

With the increasing importance of financial loans in home purchases in urban China, the role of housing loans in the accumulation of housing wealth needs to be unraveled. Using the data from the 2017 China Household Finance Survey (CHFS), this study investigates the use of housing loans and their impact on housing wealth inequality. It has been found that people with higher socioeconomic status and institutional advantages benefit more from housing provident fund loans and are more likely to fully invoke different financing channels to accumulate housing wealth. On the contrary, disadvantaged groups have to resort to costly market-based mortgages to finance their home purchases. This leads them to fall further behind in housing wealth accumulation. The spatial stratification of housing wealth accompanying the urban hierarchy was also observed and found to be closely linked to the type of housing loans. In this increasingly financialized era, relying on financial instruments in the process of household asset accumulation may further amplify the existing wealth inequality among social groups.
Ceftazidime-Avibactam as Salvage Treatment for Infections Due to Carbapenem-Resistant Klebsiella pneumoniae in Liver Transplantation Recipients

Background Ceftazidime-avibactam (CZA) has been approved in vitro activity against carbapenem-resistant K. pneumoniae (CRKP), but the experience for the treatment of CRKP in liver transplantation (LT) recipients was limited, and previous data on its efficacy in this setting are lacking. Methods LT recipients with CRKP infection who received CZA treatment were reviewed retrospectively, microbiological and clinical response, adverse events were also assessed. The primary outcome was 30-day mortality after CZA administration. Results CZA was used in 21 LT recipients (including 4 pediatric patients) with CRKP infections after failure with other antimicrobials. CZA was administered as monotherapy in 4 patients. Median time from the onset of CRKP infection until the initiation of CZA treatment was 2 days (IQR, 1–6.5), and the median treatment duration was 12 days (IQR, 8.5–18.5). The mortality at 14 days, 30 days and all-cause was 28.6%, 38.1% and 42.9%, respectively. In adult patients, clinical response of 14 days and 30 days was 70.6% (12/17) and 58.8% (10/17), respectively, while in pediatric patients the 14-day and 30-day clinical response were both 75%, respectively. The relapse rate during the treatment developed in 3 patients after 30 days with the cessation of CZA monotherapy. CZA resistance was not detected in any case and 3 (3/21, 14.3%) patients developed acute kidney injury related to uncontrolled infection. Conclusion CZA shows promising results, even in monotherapy, for the treatment of patients with severe infections due to carbapenem-resistant K. pneumoniae among LT recipients. The emergence of resistance to CZA was not observed.
Interrelation between Qai’lullah, Blue Light Exposure and Neurocognitive Performances: A Short Review

Qai’lullah or napping is a phenomenon that is widely practiced in the world. Islam advocates mid-day napping as it is primarily practiced by the Prophet Muhammad (pbuh). Scientists and scholars also acknowledge the benefits beyond this practice after various research and studies done. Hence, this article emphasizes topic of sleep in Islamic insight, their stages of sleeps according to Quran and the practiced of Qai’lullah or mid-day napping. The high-energy blue light exposure from the natural source, Sun and also digital screens reported reduce visual contrast and affect the sharpness and clarity by creating glares lead to mental and physical fatigue. Thus, a short nap in the mid-afternoon helps to boost memory, lift our mood, and improve job performance. The effect associated with qai’lullah are also being reviewed including improved the neurocognitive performance, alertness, recover the loss night sleep and enhanced the quality and increased memory consolidation in people.
Dynamic Gravity Model for Hurricane Evacuation Planning

The paper presents a dynamic gravity model to estimate time-dependent origin–destination (O-D) trip tables for hurricane evacuation with survey data from Hurricane Floyd in South Carolina in 1999. The objective is to test whether a dynamic gravity model with a revised impedance function can be used successfully to model hurricane evacuation destination choice. A static gravity model is used to estimate dynamic O-D matrices on the basis of which the dynamic gravity model is subsequently calibrated, because the dynamic O-D movement observed from the survey data is too sparse to allow estimation of the dynamic gravity model. The static gravity model was developed with a combined impedance function and describes evacuees' travel behavior. The model was estimated through a chi-square minimization process. The model was found to produce a trip length distribution that was statistically significantly similar to observed values. A time-dependent travel demand was estimated on the basis of a sequential logit model. With the trip distribution from the static gravity model and an expansion factor, time-dependent O-D trip tables were computed. Dynamic traffic assignment was then performed to provide time-dependent O-D travel costs. The static gravity model was extended into a time-dependent version in which the time-dependent travel cost, distance from the projected path of the hurricane to the destination, and remaining accommodation at the destination feature in the formulation. The model is solved by ordinary least-squares regression after transformation. The time-dependent gravity model was found to perform well by comparison of predicted and observed trip length distributions.
Exploring the Diverse Immune and Genetic Landscape of Psoriatic Arthritis

Psoriatic arthritis (PsA) is characterized by delays in diagnosis and modest effect of treatment in terms of joint response. An understanding of molecular pathomechanisms may aid in developing diagnostic and prognostic models. Genetic susceptibility (e.g., HLA class I genes, IL-23-related genes) can be responsible for the pattern of psoriatic manifestations and affinity for tissue involvement. Gene expression analysis indicates an inflammatory profile that is distinct for PsA, but disparate across tissues. This has clinical implications, as for example, dual blockade of IL-17A and IL-17F can lead to superior clinical effects if there is differential expression of IL-17 receptors in tissues. Structural and functional impairment of barrier tissue, including host-microbiome interactions, may be the source of immune activation. Interplay between different cell populations of innate and adaptive immunity is emerging, potentially providing a link between the transition of skin-to-joint disease. Th17 subsets, IL-17A, IL-17F and IL-23 are crucial in PsA pathogenesis, with both clinical and experimental evidence suggesting a differential molecular landscape in cutaneous and articular compartments.
A NOVEL FOAMY COLLAGEN AS A DURAL SUBSTITUTE

This study developed an innovative foamy collagen dural substitute. The foamy collagen was prepared by mixing collagen hydrogel and high-pressure oxygen in a stainless steel bottle as a container. A foamy collagen with 101 ± 43 μm in pore size and 50.5 ± 5.1% in porosity formed after release from the container. In the results of the in vitro degradation experiment, foamy collagen degraded slower than the commercially available DuraGen treated with 5 units/mL of collagenase solution. DuraGen degraded completely within three hours and foamy collagen had 39.2% (mean) of its original mass remaining 24 h after immersing in collagenase solution. The oxygen bubble structure was immobilized by the collagen fibrillogenesis and remained intact 3 and 7 days after subcutaneous implantation of the foamy collagen in rats, without any escape or merge of the oxygen bubbles. Fibrous tissue proliferated along the porous structure from the edge of the foamy collagen according to the histology analysis of subcutaneous implantation experiment in rats. The results of in vivo rabbit duraplasty experiment showed that the regenerated dura in foamy collagen group was thicker than that in DuraGen group, and was comparable to the native dura mater, without causing any adverse effects, such as intracranial pressure increase or cerebrospinal fluid leakage.
Learning to deliver service‐enhanced public infrastructure: balancing contractual and relational capabilities

Public agencies in construction increasingly involve the private sector in the provision of various public goods and services. With the extension of private sector involvement, public agencies are confronted with the need to acquire new capabilities. The results of two comparative case studies from the UK and the Netherlands show that the level and focus of capability learning change over time. Public agencies follow different learning trajectories and need to address the dynamic character of the learning in order to successfully employ (a) contractual and (b) relational capabilities in their exchange relationships.
Examining the relationship between the unique work experiences and cultural orientations of police officers

ABSTRACT The current study builds upon limited prior research that has assessed the relationship between elements of police culture and a host of unique officer work experiences (e.g. tenure, assigned shift and area, the number of shifts and areas worked, supervisory experience, specialized unit assignment). The sample consists of survey data from over 700 officers from a large police department in the western United States. The results demonstrated that while officers’ assigned shift and area had little effect, a number of other experiences were influential. Officers who had worked a greater number of shifts in their career were more likely to view policing as dangerous; and patrol officers were more likely to view management negatively. Further, specialized unit officers were less likely to view citizens negatively and less oriented toward order-maintenance or community policing than their patrol counterparts. Importantly, experience as measured simply by the number of years on the job, as opposed to other unique work experiences, showed that more senior officers were less likely to view citizens negatively and believe crime fighting should be a top priority, but more likely to view top management through a negative lens. We conclude by reviewing several implications and directions for future research.
